L. Bean Background In 1912 Leon Leonwood Bean developed the Maine Hunting Shoe (a blend of lightweight calfskin uppers and elastic bottoms). He got a rundown of alien Maine chasing permit holders, arranged an illustrative mail-request roundabout, set up jump in his siblings storm cellar in Freeport, Maine, and began an across the country mail-request business. The initiation of the U. S. Post Offices household package post administration in that year gave a methods for conveying requests to clients. At the point when L. L. Bean kicked the bucket in 1967, at 94 years old, deals had reached $4. 75 million, his organization utilized 200 individuals, and a yearly list was conveyed to a mailing rundown of 600,000 individuals. L. L. s Golden Rule had been Sell acceptable product at a sensible benefit, treat your clients like people, and theyll consistently return for additional. At the point when Leon Gorman, L. L. s grandson, succeeded him as president in 1967, he tried to extend and modernize the business without going amiss from his granddads Golden Rule. By 1991, L. L. Bean, Inc. as a significant cataloger, maker, and retailer in the outside brandishing claim to fame field: Catalog deals in 1990 were $528 million, with an extra $71 million in deals from the companys 50,000 square-foot retail location in Freeport. Twenty-two unique lists (regularly alluded to as books by organization employees)†114 million pieces in all†were sent that year. There were 6,000,000 dynamic clients.

Bean had not extended its retail activities past the one store in Freeport, Leon Gorman differentiated the direct-arketing (index) and retail organizations.

Retailers must be imaginative, limited time, pizzazzy, stock arranged. Its extreme to amass one supervisory group that can deal with the two capacities. 1 Product Lines L. L. Beans product offering was characterized progressively (see Exhibit 1). At the most elevated level of conglomeration were Merchandise Groups: mens and womens embellishments, mens and womens attire, mens and womens footwear, outdoors gear, and so forth. Inside each Group were Demand Centers; for example, womens attire had as Demand Centers weave shirts, sweaters, pants, skirts, Jackets and pullovers, and so on.

Corporate Strategy, Harvard Business School Case (581-159), 1981. 21tems were additionally separated by size into stock-keeping units, or SWs. This was finished by applying standard size-dispersion breakdowns. Albeit an unseemly circulation could prompt exorbitant stock of certain sizes and stockouts of others, the board concern was coordinated to the thing level, since there was no proof of a superior framework than accepting that the appropriation of in terest by size would carry on in the uture as it had previously, and would be indistinct starting with one thing then onto the next. Things were likewise grouped into three occasional classifications (spring, fall, and all year), and into two extra classifications (new or never out) that depicted whether the thing was an ongoing or increasingly perpetual individual from the companys contributions, and therefore described the measure of recorded interest information accessible for the thing. The Bean Catalogs The major catalogs†spring, summer, fall, and Christmas†each turned out in a few forms. A full inventory, running from 116 to 152 pages, went to Beans normal ustomers. A littler possibility index was flowed to likely clients; it contained essentially a subset of things from the full list. (Bean recognized such possibility clients in an assortment of ways, for instance, through the acquisition of mailing records, or by recording beneficiaries of endowments from other Bean clients. ) what's more, various claim to fame catalogs†Spring Weekend, Summer Camp, Fly Fishing, and so forth † introduced things that were interesting to that list, just as certain things found in the significant lists. There was some cover available for use: the best ustomers got practically all the lists, and those clients known, through past buying conduct, to be keen on different claims to fame may get a proper strength index notwithstanding the occasional full inventories. Thing Forecasting Each list had a development time of around nine months, and its creation included promoting, plan, item, and stock experts. For instance, the underlying conceptualization for the Fall, 1991 season started in October, 1990. Fundamental conjectures of complete deals for each index were made in December. Item directors eveloped primer thing estimates by book in the December, 1990 to March, 1991 time period. Format and pagination of the books started in January, 1991. Starting duties to sellers were made in January and February. In the ensuing months, as the indexes came to fruition, thing estimates were over and over amended lastly solidified by May 1. By early July a high contrast adaptation of the format was accessible inside. Now, the item supervisors gave off their product offering to the stock directors. The finished Fall 1991 inventories were in the possession of clients around August 1 . As the index

Creating Daily Writing Habits

Creating Daily Writing Habits The following transcript is an attenuated QA from my recent interview with Thom Chambers in the premier issue of Micropublisher magazine. Thom Chambers: Do you currently have a daily writing routine? Are there set hours that you work, or a daily word count you look to reach? JFM: I wake early. As soon as I’m awake, no matter the time, I get out of bed immediately and start my day: getting out of bedâ€"that’s the secret. My writing space looks like this. I write six or seven days a week, three to six hours a day, but I dont have a routine. As a slow writer, and an even slower reader, I often write only 500 words on a good day, and I rewrite vigorously. I go through numerous drafts of whatever I’m writing; several chapters in As a Decade Fades  went through 20 or 30 drafts. I remember spending about ten hours on the first paragraph of that book, which isn’t a long one. At the end of the day, I’m happy if I’ve written a full page: one good page is enough. If you were to give one piece of advice for aspiring writers, what would it be? Sit in the chair every day: even if you don’t write, plant yourself in the chair daily for a few hours and eventually the words will come. And ensure you eliminate distractionsâ€"no Internet, no TV, no radio, no phone. If you’re truly passionate about writing, you’ll do these things and write. Following on from that, a lot of people draw inspiration from seeing behind the scenes of a lifestyle to which they aspire, so can you walk us through a typical day in the life of Joshua Fields Millburn? For his website, Zen Habits,  my friend Leo Babauta asked me to write an essay, A Day in the Life of a Minimalist, to provide a panoramic view of one of my typical days.

Police Dogs Free Essays

Police Dogs Breah Ratlif Animal Science AY105-02 12-12:50 Cute, fun, loving, cuddly, outgoing; these are only a few words to describe the animals that we have come to know and love as a part of our families. Dogs have been man’s best friend for hundreds of years and were the first animal to be domesticated because they are great as companions, highly intelligent, and were found to be very useful in human’s everyday lives. Even though they made excellent house pets they were highly successful at working side by side humans as well. We will write a custom essay sample on Police Dogs or any similar topic only for you Order Now They are not limited to being just best friends, but they have been found to be protectors and saviors as well, to their owners, others people and even other dogs too. One type of working dogs in particular that needs to be recognized for their tremendous efforts, and hard work is none other than police dogs. There are many dogs that will help humans in time of need. For example there are guide dogs, search-and-rescue dogs, and bomb-or-drug- sniffing dogs just to name a few. They really dedicate themselves to the jobs that they live to do. But few dogs are asked to go above and beyond to lay their lives on the line to protect and serve as much as police dogs. These dogs are trained to do specific things. The basic description of what police dogs do is to guard their handler, and assist him in numerous tasks, such as finding, intimidating, and holding suspects, or investigate the scene of a crime. Some can even be trained specially for detection work. It is interesting how on one hand they are a loving member of a family, then when it is time to do some police work they can take down and attack humans so easily. In order to lead this type of life style this dog has to have some very important traits that other dogs may not have. They must come from intelligent, strong, dedicated, and aggressive but obedient lines of dogs, and while even the trait to be too aggressive is not very desired the strongest traits that police dogs must have are self-control and obedience. Police dogs are usually members of the working dog breeds. The dogs today come from a long line of purebred working dogs that were bred because of their high intelligence and strength. There are other breeds that have traits that could greatly contribute to police work as well such as hunting dogs or herding dogs because of skills like hunting and tracking for instance. There are several dogs that qualify for police work and are known for their bravery and drive. The German Shepard is the most common and most popular dog for police work. Lab Retrievers, Belgian Malinois, Doberman Pinschers, Akitas, Terriers, Boxers, Spaniels, Bloodhounds, the Bouvier de Flandres, Rottweiler’s, Collies and Dutch Shepherds have been known to also be used for different types of police work. K-9 police work is more than just brute strength and skin prickling growling. Tracking down or smelling for drugs, weapons, evidence, cash, bodies, criminals; holding on to criminals; and even protection work are all a part basic everyday life. Just the presence of a having a police dog by the officers side can prevent physical harm from being inflicted upon the police officer by the suspect/criminal, ultimately leading to lesser chances of the officer getting harmed in any way. Police dogs today are not bred or employed to be vicious animals towards people in any sense; in all actuality most are trained or supposed to be trained to enjoy their work as hard as that may seem. What happens is it all starts off as fun and games. Chasing and grabbing is introduced to them as games when they are young pups to get them use to it. They usually play these types of games only when the handler or in other words a police officer, gives the right command for them to do so. The goal of the games is not for the dog to actually â€Å"bite† its opponent but more to merely hold on to it for as long as possible till the officer it works with gives the dog the command to let go. This tactic is mostly to insure that the suspect/criminal does not get away until the officer can catch up and take care of him/her their self. This grab is strong and hard. There is always a large possibility that the suspect/criminal can/will be bitten if they attempt to fight off the dog but when thinking about it even the dog â€Å"gripping† onto the suspect will inflict a bite. They would not be able to hold the suspect as well if they did not apply pressure into their grip. Before any dog has to be turned loose, they try to intimidate the person first by giving them a warning that if they start to run, the dog will be released and will chase after them. A barking tactic is also used to scare the person into not running away. Even in a case where the officer and dog seem to have the upper hand, there are many situations where the tables can be completely turned. Both the officer and the dog are trained to work together as a team. They must be able to fully trust and understand one another especially when they are placed in extremely dangerous and stressful situations. It is the responsibility of the officer the dog is being handled by to only use the dog when the situation absolutely calls for it. Any other way would be very inappropriate and would be a terrible miss use of the animal. Not being responsible could also put the dog in more of harm’s way which can take a definite turn for the worst. Going into depth of the most popular and common of the police dogs the â€Å"the German shepherd only came into being a little over 100 years ago. A German shepherd enthusiast, fascinated with the intelligence, strength and agility of the country’s native sheep dogs, established the breed, which spread throughout the world when Allied soldiers saw how the Germans used them as messenger, tracker and guard dogs during World War 1. After the war, the name German Shepherd Dog (Deutsher Shaferhund) was dropped in favor of the Alsatian Wolf Dog (After the Alsace-Lorraine German/French border region), as it was thought that the word â€Å"German† would make the breed unpopular, and Alsatian continued to be used for the breed until the 1970s. Your Best Friend: The Dog, pg. 50. The other types of working dogs that are used a lot more than the rest of the working breeds in police work are the Belgin Malinois (very similar to the German shepherd), the Doberman, Boxer and Rottweiler. One main reason they are under the German shepherd or Belgin Malinois could be because of factors such as tolerance for instance. That can be di rected towards weather and other such factors. Based off of observation with their fur coats being shorter they do not do as well in colder climates or seasons and police duties are year round. Still the loyalty, obedience, and ability to react quickly in certain situations, make the Doberman a great breed for police dog training. The brute strength of a Rottweiler, along with their intelligence and protective nature, makes them popular to some and in case there are no German shepherds around Rottweiler’s are great substitutes for getting the job done. The same goes for the boxer with it being fearless, loyal and strong they are also respected to be a strong guard dog and used in police work. This topic was found to be interesting and unique because dogs are one of the few animals people can really rely on to be there no matter what. Humans can rely on dogs to be more than great companions and friends. They have traits of loyalty, fearlessness, loving, strong, dedicated, and intelligent. The list could go on but more than any pet they will stick by your side till the very end. Dogs were also found to be great at being put to work. Their senses are far better than humans. They have Excellent hearing and smelling. According to facts. randomhistory. om a dog can locate the source of a sound in 1/600 of a second and can hear sounds four times farther away than a human can. Also Touch is the first sense the dog develops. The entire body, including the paws, is covered with touch-sensitive nerve endings. Dogs have a wet nose to collect more of the tiny droplets of smelling chemicals in the air. When it comes to their smelling abilities a dogs sense of smell is 50 times for sens itive than a humans. Some dogs can smell dead bodies under water, where termites are hiding, and natural gas buried under 40 feet of dirt. They can even detect cancer that is too small to be detected by a doctor and can find lung cancer by sniffing a person’s breath. It does not hurt that dogs can be trained to do just about anything so this makes them perfect for doing work. A good example of something a police dog can be trained to do is known as â€Å"Aggressive alert† which the most common of the alerts it is taught to them. Aggressive alert is what the dogs do to show indication of an odor or substance that they are trained to detect by vigorously scratching and barking at a particular item. Another alert that is taught to police dogs is called â€Å"Passive alert†. The dog will sit when it smells the odor that it is trained to detect. Passive alert is common when it comes to explosive detection canines and narcotic detection canines. I feel that there are many pros and cons to having police dogs on the force. I personally like the fact that we have dogs involved in police work to a certain extent. Where some humans lack the stamina to run and catch up with a suspect that has decided to give an officer the chase, the police dog can make up for what he/she lacks. Dogs are great runners and if exercised properly they can almost run for miles. This makes them great at catching up with suspects to get a good grip on them and hold them until the officer can catch up and give the dog the command to let go. Also by using the dog it allows for the officers to refrain from using bullets if they are not exactly necessary, and unlike a gun, a dog almost never misses. This could lead to saving more lives whether innocent or not. I also think that the dogs really have been one of the best decisions that the police for could have made when it came to looking for better ways to do their job in multiple aspects. This is really in consideration to the dog’s senses being way more sensitive than that of a human. Since we are unable to smell certain things that are not very pungent or in close range to our noses our dogs can definitely smell what we cannot especially particular breeds of dogs that have a better sense of smell than others. There was one particular instance that I can personally say caught my attention. I had an open bag of cookies in my purse and there was a beagle puppy and a boxer puppy in front of me allowing me to pet them. Instantly the beagle puppy could smell the bag of cookies that I had in my purse sitting behind me before the boxer puppy could. It was so amazing to me to see how the dog reacted to the smell of the cookies. From previous knowledge of beagles I know that they are also working dogs and are great for smelling things and hunting things down. Police dogs are notorious for sniffing out drugs among other things. I remember being in high school and middle school and they would have days where they would bring police dogs in to smell the lockers of students to check for drugs. They always made sure students stayed in the class room for safety reasons I’m sure. They are also good for being used in airports where people are constantly coming and going from other states and countries so it is highly important to know what people have on them when boarding or getting off of a plane may catch things that the metal detectors, x-ray like machines and security guards may miss. Their highly sensitive noses can also be used to track down one specific person, leading to a faster take down of suspects as well as finding those who are in need. Some cons of police dogs are the actual harm they can cause a person while trying to catch and hold them while they wait for their trainer. They can inflict puncture wounds and if they grip the wrong part of the human body can lead to some pretty serious damage. There may also be case where the dog may attack the wrong person. Even though police dogs are extensively trained and are trusted partners police officers, they still possess canine instincts. A dog gets overexcited or becomes frightened may bite a handler, a suspect or a member of the public that is completely innocent. Police departments cannot make guarantees that these out of hand attacks will not happen, and it is possible for police agencies to be taken to court by the victims and forced to pay compensation for any damages caused by the out of control dog. Depending on how well the dog has been handled it does run the possibility to become aggressive. Another down fall is that police work can be beyond dangerous, and dogs are also susceptible to being injured or even killed while on duty. There have been cases where dogs have been killed by suspects that may have wielded knives and guns. Some people may view this as a disadvantage of using police dogs since the animal does not have a choice in terms of a career and emergency care is not all ways a call away for our canine companions especially at certain hours of the night. Mainly I do believe that having dogs doing police work does good than it does bad. There are more positives to adding dogs to the picture than negatives.

The domains which are included are healthcare, construction, water, space and agriculture. These sectors are transforming their infrastructure to give support to Internet of Things. Prediction of computation, storage and connectivity are possible and their related solutions are also identified by using Internet of Things. Applications of Internet of Things such as management of infrastructure in rural and urban areas, monitoring health remotely, transportation systems, emergency system notification and shopping systems are depending upon Internet of Things based devices. In this present digital world, it is very much important to learn the ba sis of the emerging technology of Internet of Things. Literature Review on Internet of Things Review 1 Chosen Article: Understanding the Internet of Things (IoT) According to the article, to make a change in life of individual and productivity of enterprises internet things are needed. From the article it is reviewed that the network of intelligent smart devices that are local, potential to extend and enhance the fundamental services in security, utilities, healthcare, education, logistics and transportation Internet of Things are needed [3]. These Internet of Things devices provides new ecosystem for the development of the application. According to Cui, a great effort has been given to the industries of early stages to develop towards maturities that are driven by same understanding with particular nature of opportunity [10]. The characteristics that are distinct in the areas business, charging models, service distribution, capabilities that are required to deliver the Internet of Things devices and also different demands of putting these services on mobile networks. These Internet of Things devices provides new ecosystem for the development of the application. From this article it can be analyzed that common understandings of characteristics of Internet of Things will allow the partners to unite more efficiently in order to establish in the market and get benefit from society and consumers. For understanding IoT (Internet of Things) following things are described in this article: The services of Internet of Things that enhances life- The life enhancing services are enabled by Internet of Things through different sectors of economy. The distribution model of services of Internet of Things is made globally- The needs of the customers are meeting by models of global distribution and global services that are consistent. New commercial models are employed by Internet of Things- To support the mass deployment globally; an opportunity is given by Internet of Things for commercial models that are new. For the applications of Internet of Things new capabilities are developed- The maximum revenue comes from the value added services and the operators are making capabilities that are new to address areas of new services. The last thing that is stated in this article to understand Internet of Things is that demand is increasing and are differing on mobile networks- The behavior of applications and devices places new and different demands for mobile networks. Review 2 Chosen Article: Internet of Things: Converging Technologies for Smart Environments and Integrated Ecosystems. According to the article Internet of Things: Converging Technologies for Smart Environments and Integrated Ecosystems, Internet of Things is developing every day [11]. The potential of Internet of Things is estimated by combining similar approaches of technologies and also concepts that includes cloud computing, semantic technologies, robotics, future internet and big data [9]. The idea of combining these technologies is not new but has become evident because the concepts have started to release synergies. There are many numbers of factors that helps in increasing the maturity of Internet of Things which tends to full exploitation of Internet of Things. The factors that are mentioned in the article to increase the maturity of Internet of Things are as follows: No such clear approach is given for utilization of identifiers that are urgent and also number the spaces for different kinds of volatile and persistent objects globally. No such development of Internet of Things architecture references like ARM (Architecture reference Model) of project and accelerated use of Internet of Things. Semantic interoperability that is used for exchanging the sensor data in environments that are heterogeneous have less rapid advance. The ownership and trust of data of Internet of Things are difficult to develop that is used for innovation and also giving privacy and security in a complicated environment. There lays a difficulty to develop business which enhances the full potential of the Internet of Things. The learning and testing environment are missing which increase both experimentation with sensor networks and also increases innovation via experience and reflection. The roaming charges that fall in practical aspect of Internet of Things have application of large range sensor and also miss the availability of technical aspect and network connectivity that are reliable. If these hurdles are overcome, then Internet of Things will lead to better exploitation in the areas of cross domain interactivity, awareness of real world is increased and also utilizing problem solving space that are infinite [12]. The further solutions and approaches to make Internet of Things better exploited are discussed briefly in this article. Review 3 Chosen Article: An Overview Understanding the Issues and Challenges of a More Connected World. The concept that is explained in the article An Overview Understanding the Issues and Challenges of a More Connected World is that it is an important part in the technology sector of engineering, policy and industry [8]. The Internet of Things has become a specialty press and also a popular media in the news. The technology of Internet of Things has provided a wide area in the products, systems and also the sensors which are needed in computing power, network interconnections and electronics miniaturization that offers new opportunities that were not possible previously. The potential of Internet of Things is estimated by combining similar approaches of technologies and also concepts that includes cloud computing, semantic technologies, robotics, future internet and big data [1]. The idea of combining these technologies is not new but has become evident because the concepts have started to release synergies. Applications of Internet of Things such as management of infrastructure in r ural and urban areas, monitoring health remotely, transportation systems, emergency system notification and shopping systems are depending upon Internet of Things based devices. In this present digital world, it is very much important to learn the basis of the emerging technology of Internet of Things. The Internet of Things products used by consumers are detailed in this article [14]. The devices are home automation system, devices of energy management makes the world to move towards a smarter home. This Internet of Things offers more energy and security the house [2]. Other devices of Internet of Things that are discussed in this article are monitoring health devices and wearable fitness and also medical devices that are network enabled for transforming the services of healthcare [6]. The technology of Internet of Things provides benefits to the elderly people and also people with disabilities so that the quality of life is increased at a very reasonable cost. Systems like intelli gent traffic system, roads that are sensor embedded and networked vehicles are the systems of Internet of Things which leads to smart cities and helps to decrease the congestion of cities and also helps in consumption of energy. This article explains that Internet of Things gives possibility to transform energy production, industry and agriculture by increasing data availability in the productions that are made of networked sensors [13]. The challenges and issues that arise with Internet of Things are considered as important aspect in the digital world and to mitigate them relative procedures are taken. Three security issues of IoT Data Encryption Numerous amounts of data is collected by the devices of Internet of Things. Data processing and data retrieval is considered as the internal part of the Internet of Things environment. The data that are put in the devices of Internet of Things are very personal and also needed to give a protection via encryption. The security issue of Internet of Things is secured by using Secure Socket Layer Protocol (SSL) when the information is online [5]. The website that are used in daily life has Secure Socket Layer Protocol certification to give a protection to the and also encrypt the user data that are online. Only the half part of the website is protected by SSL and the other side is to give protection to wireless protocol side. The data that are transferred without wire also needs encryption process. The location of the sensitive data is to be kept personal and it is to be kept in mind that only the user knows about the data. So, for inbuilt encryption, wireless protocol is to be installed . Data Authentication When the data is encrypted, and then comes the chance of getting hacked. The data is to be protected from hacking. To security to establish authenticity of data those are communicated to the receiver and from the sender in an Internet of Things is compromised [8]. For an example, in a temperature sensor device for smart home, even after encryption of data, if someone hacks the system and send fake data instructing the sensor to make the temperature hot instead if cooling or vice versa. So there must be authenticated data that are sending to the device. Security risk comes from authentication problem of the information. Hardware Issue The hardware creates a problem from the beginning of Internet of Things [16]. The makers of Internet of Things devices, the chipmakers of devices such as Intel and ARM are focusing more on security purpose because with all time new generation evolving, new ways are coming to as a risk to the devices. But then also the security gap does not fill up. The modern architecture of the devices of Internet of Things faces a security problem mainly in the chips that are fixed inbuilt in the Internet of Things devices [15]. Making new devices and implementing new chips make the price of the device go high. To ensure the security process, the chips are remade and thus become expensive. The complex design of the chips also requires more power consumption which gives a challenge to the Internet of Things devices. Better approaches are to be inbuilt so that the devices are affordable and are safe from security risks. Mitigate Security Threat The solution for mitigating risk that is related to hardware security is done by testing the system before the framework is being installed. Four such methods of testing a device before implementation is discussed below- Testing hardware- The best and most significant way to mitigate the security risk of hardware in Internet of Things is to test the framework of the place [4]. The testing procedure includes- device range, capacity and latency and manufacturability test. In Device range the coverage network of Internet of Things is paramount. The range of the application is to be specified before the device application. For example if the technology of Zigbee is applied on the devices network that is to be implemented, then the numbers of repeaters are to needed is to be fixed so that the communication range id fixed. The capacity of handling the speed of device network in bytes per second and the latency signifies the time that is taken to transfer the data between endpoints of application [3]. The latency and the capacity of the applications of Internet of Things are to be improved so that the performance increases. The applications and the devices of data intensive are to be tested thoroughly for balancing the capacity and latency of the device. Manufacturability test includes testing the devices that are taken from other manufacturers so the when they are accumulated to make a device, it does not creates a problem. The devices are to be tested in dividually. Acknowledgment Applications of Internet of Things such as management of infrastructure in rural and urban areas, monitoring health remotely, transportation systems, emergency system notification and shopping systems are depending upon Internet of Things based devices. In this present digital world, it is very much important to learn the basis of the emerging technology of Internet of Things. The life enhancing services are enabled by Internet of Things through different sectors of economy. Different features of business, implementation and research that are related with Internet of Things are needed in industries, government and academics.

Acid Rain Essays (3433 words) - Chemistry, Inorganic Solvents

Acid Rain What is acid rain? Acid rain is the term for pollution caused when sulfur and nitrogen dioxides combine with atmospheric moisture. The term 'acid rain' is slightly misleading, and would be more accurate if deemed 'enhanced acid rain', as rain occurs acidic naturally. Acidity is measured on what is know as the pH scale. Fourteen is the most basic, seven is the most neutral, and zero is the most acidic. Pure rain has a pH level of 7, which is exactly neutral. The acidity of rain is determined by the pH of pure water in reaction with atmospheric concentrations of carbon dioxide, resulting in carbonic acid. These particles partly dissociate to produce hydrogen ions and bicarbonate ions. A bicarbonate atom is an ion formed by one hydrogen atom, one carbon at atom, and three oxygen atoms, and is very effective in natural waters at neutralizing hydrogen ions and reducing acidity. The dissociation results in the natural acidity of pure rain, which is moderately acidic at a pH of 5.7. Rain less than 5.7 is considered 'acid rain', meaning it has reacted with acidic atmospheric gases other than carbon dioxide, such as sulfur dioxide and nitrogen dioxide. Sulfur dioxide is produced by electric utilities, industrial, commercial and residential heating, smelters, diesel engines and marine and rail transport, which creates sulfuric acid in rain. Nitrogen dioxide will also react with the rain, caused largely by transportation (cars, trucks, planes, etc.) and electric utilities, producing nitric acid. There is a certain degree of naturally occurring acidity in rain water. This acid is from reaction with alkaline chemicals, found in soils, lakes and stream, and can occasionally occur when a volcano erupts as well. Bacterial action in soils and degasing from oceanic plankton also contribute to the acidity found in rain. More than 90% of the sulfur and 95% of the nitrogen emissions which occur in North America are due to the pollution created by humans.1 How Is Acid Rain Formed? Acid rain consists mainly of acids formed in the atmosphere. It consists of the oxides of sulfur, SO2 and SO3, and of nitrogen NO and NO2. Let us examine the major contributor to acid rain, sulfur oxides. Natural sources which emit sulfur dioxide include volcanoes, sea spray, plankton and rotting vegetation. Despite these natural occurrences, the burning of fossil fuels (such as coal and oil) can be largely blamed for the emissions. The chemical reactions begin as energy from sunlight, in the form of photons, hit ozone molecules (O3) to form free oxygen (O2), as well as single reactive oxygen atoms (O). The oxygen atoms react with water molecules (H2O), producing electrically charged, negative hydroxyl radicals (HO). These hydroxyl radicals are responsible for oxidizing sulfur dioxide and nitrogen dioxide, which produces sulfuric acid and nitric acid. Some particles will settle to the ground (in the form of acid deposition) or vegetation can absorb some of the SO2 gas directly from the atmosphere. When sulfur dioxide comes in contact with the atmosphere, it oxidizes and forms a sulfate ion. It becomes sulfuric acid as it joins with hydrogen atoms in the air and falls down to earth. Oxidation occurs most in clouds, especially in heavily polluted air, where other compounds such as ammonia and ozone help to catalyze the reaction, increasing the amount of sulfur dioxide changing to sulfuric acid. Not all of the sulfur dioxide is converted to sulfuric acid, and it is not uncommon for a substantial amount to float up into the atmosphere, move to another area, and return to earth as sulfur dioxide, unconverted. S (in fossil fuels) + O2 =* SO2 2 SO2 + O2 =* 2 SO3 Much of the sulfur dioxide is converted to sulfur trioxide in the atmosphere SO3 + H2O =* H2SO4 The sulfur trioxide can then dissolve within water to form sulfuric acid Nitric oxide and nitric dioxide are mainly from power plants and exhaust fumes. Similar to sulfur dioxide, reactions are heavily catalyzed in heavily polluted clouds where iron, manganese, ammonia and hydrogen peroxide are present. Also, the formation of nitric acid can trigger further reactions which release new hydroxyl radicals to generate more sulfuric acid. The following is a typical reaction, which is direct combination of nitrogen and oxygen at the high temperature inside a car engine. N2 + O2 + heat =* 2NO 2NO + O2 =* 2NO2 This nitrogen monoxide immediately reacts with oxygen and forms nitrogen dioxide in the following reaction 3NO2 + H2O =* 2HNO3 (aq) + NO The nitrogen will then dissolve in water in

Dissociative Identity Disorder in Black Swan Essay

Dissociative Identity Disorder in Black Swan Essay Black Swan Film Review Essay Black Swan Film Review Essay Black Swan is a psychological thriller by Darren Aronofsky about a ballerina who slowly goes insane during the time of repetition for the ballet performance Swan Lake. The movie is made very well in terms of psychopathology. The main heroine, ballerina Nina, is so immersed in her own perception of the ballet performance that she begins to identify real life with the plot of the ballet, and herself with a swan: firstly, with White - Odette and then with Black - Odile. Finally, the latter prevails. Nina suffers from dissociative identity disorder. Speaking of everyday language, it is a split personality. Dissociative Identity Disorder in Black Swan Psychologists are well aware of this kind of disease, and nowadays it is thoroughly studied. Several features inherent to dissociative identity disorder are shown accurately in Black Swan. Meanwhile, the other psychological disorders were used to create an atmosphere of the film and do not correspond to the disease symptomatology. Without a doubt, among dissociative disorders, the most â€Å"cinematic† type of the illness is a split personality or multiple personalities. The patient has several â€Å"alter personalities† that exist in parallel, each one in its own reality. Drama potential of the problem was proved in Black Swan. Apparently, authors of the film are clearly impressed by the fact that an infantile girl and a brutal killer can peacefully coexist in the one person. Severe stress experienced by the individual often becomes the cause of the syndrome of â€Å"splitting† (Bruch, 2015). In the thriller Black Swan, it is clearly demonstrated what happens when the â€Å"realities† of the two personalities accidentally begin to come into contact. The main heroine gets the lead role in the ballet. It is the role of Swan Queen, and it involves two opposite sides. Nina must fulfill the role of the White and Black Swan. First one fits her perfectly because Nina was like White Swan: modest and shy, nervous and fearful. However, Black Swan, the other part her performance, turned out to be an overwhelming task. Since it embodied dissolute and evil forces of human nature, Black Swan was the opposite of her own character. Therefore, to immerse in the role, Nina had to change herself, to become a â€Å"black†, as well as awaken own dark and evil nature. Eventually, the acting exercise turned into a real obsession or paranoia. Black Swan moved into Nina, displacing White. She has become an embodiment of evil for the role that ultimately she performed undoubtedly perfect. However, White Swan and its light essence could not exist in Nina anymore. It would not be a mistake to suggest that Nina suffers from dissociative identity diso rder. Dissociative identity disorder is a very rare psychiatric disease from the group of dissociative disorders in which an individual’s personality is split, and it seems that there are several different characters (or ego states) in the body of one person (Ross, 2000). In the certain moments, there is a â€Å"switch† in a person, and one person replaces another one. These â€Å"individual† may have a different gender, age, nationality, temperament, intelligence, philosophy, respond differently to the same situation. After the â€Å"switch†, the currently active person can not remember what happened during the time another person was active (Ross, 2000). This disorder is an extreme manifestation of dissociation. It is a psychological defense mechanism in which a person begins to perceive what is happening to him or her as if it is going on to someone extraneous (Goldberg, 2014). This mechanism is useful because it allows a person to be protected from excessive, unbearable emotions. However, in cases of excessive activation of this mechanism, dissociative disorders appear. Contrary to popular belief, these disorders are not associated with schizophrenia (Goldberg, 2014). The parts of the patient’s self-identity resulting from separation (dissociation) from his or her personality can not be considered independent integrated personality. Usually, the person is not aware of the other people’s presence in the body (Lawrence, 2010). According to DSM-IV, dissociative identity disorder is diagnosed if the following criteria are present: In the patient, there are two or more distinct identities or personality states at the same time. Each of them has a sustainable model of attitude, outlook, and their own approach to reality. At least two of these identities alternately take control over the behavior of the patient. The patient could not recall important information about him- or herself, and it goes beyond the ordinary forgetfulness (Lawrence, 2010). In addition to the symptoms listed in the DSM-IV, in patients with dissociative identity disorder depression, suicide attempts, sudden changes in mood, anxiety, and anxiety disorders, phobias, panic attacks, sleep and nutrition disorders, and other dissociative disorders, hallucinations may also occur (Kihlstrom, 2005). Dissociative identity disorder is closely related to the mechanism of psychogenic amnesia. The latter is a memory loss that has a purely psychological nature without physiological disturbances in the brain. This is a psychological defense mechanism by which a person can displace the traumatic memories from consciousness. However, in the case of identity disorder, it helps individuals to â€Å"switch† (Kihlstrom, 2005). Excessive activation of this mechanism often results in the development of common everyday problems with memory in patients suffering from the identity disorder. Dissociative identity disorder is believed to be caused the by the combination of several factors: intolerable stress, ability to dissociate, a lack of care, and concern in relation to the child in traumatic experience, or lack of protection from subsequent undesirable experience. Adults with this disease often describe the situation of violence in childhood (Lawrence, 2010). These data indicate that the abuse in childhood acts as the main cause of identity disorder among patients. Some of them may not experience violence, early loss (e.g., death of a parent), serious disease, or other extremely stressful event (Lawrence, 2010). The ballerina has a mental disorder of neurotic character since adolescence. It is an obsessive self-inflicted injury that is confirmed by Nina’s mother. However, one can suggest that it was not self-inflicted wounds. It was just a child’s abuse the true nature of which the mother could not know due to busyness in developing her own ballerina career. Besides, Nina has no father. Perhaps the death of the parent was the cause of the future disorder. The reasons for dissociative identity disorder experiencing by the heroine are not completely clear in the movie. Thus, she already had the disorder. It is likely to worsen by bringing up by the mother, liability, dream, guilt, and the fierce competition. At the very beginning of the film, the heroine is said that â€Å"Perfection is not just about control. It is also about letting go†. Since that time, the split of her personality began. There are two swans: humble and aggressive. Since early childhood, Nina was taught to suppress her emotions, especially aggression. Thus, she is not able to play Black Swan. Emotionally, during the development, she stopped on the level of a small child. It can be evidenced by the look at her bedroom that is full of pink lingerie and many toys. Just killing a humble person, she was able to play Black Swan. So then, realizing what happened, to play a dying person. The starting point for the emergence of the alter ego was stress and obsession of overvalued idea of perfectionism. Its nature can be twofold: hysterical - then triumphal ballet career is expected, and schizophrenic - psychic catastrophe and professional and life fall. The presence of hallucinations is not a mandatory obstacle to the performance of the ballerina. Thus, the dual personality is created and entered Nina’s life. Its nature can be twofold: hysterical - and then waiting for the actress triumphal ballet career; schizophrenic - ahead of psychic catastrophe and professional life fall. The presence of hallucinations is not a mandatory obstacle to the ballerina’s performance. The presence of alter ego is shown in the film quite accurately. It is brightly highlighted by the mother phrase in relation to Nina â€Å"It is not my Nina†. The Black Swan personality is acting in the following scene. Nina is more and more disturbing by the fear that Lily wants to take away her role. Nina rehearses all the evening before the premiere of the ballet. She suffers from hallucinations. Nina goes to the hospital to Beth, who threw herself under a burning car and was injured. Suffering from depression, Beth takes nail file and begins to pierce her face. After unsuccessful attempts to stop Beth, Nina runs from her chambers and jumps into the elevator. There she suddenly realizes that nail file, with the help of which Beth cut her face, somehow appeared in her hands. In a fit of panic, Nina runs home. One can suggest that alter ego of Nina, Black Swan, hurt Beth. However, Nina should not remember this. This is also a mismatch between the symptoms of dissociative iden tity disorder. In the film, it was not shown that Nina forgot periods when the second person operated. She rather does not understand what is going on when Black Swan is acting. Also, the symptoms of dissociative identity disorder as depression, suicide attempts, sudden changes in mood, anxiety disorders, and phobias were absent. However, they do not always occur in this disease. A source of horror in Black Swan is the unexplained mutation of the human body. Alien personality, which grows through the skin, changes the way of thinking. However, these shocking scenes of the heroine’s metamorphosis, her moments of going crazy can not be considered completely accurate with respect to dissociative identity disorder. As was mentioned above, the person does not know that another personality is present in his or her body. Nina always thinks that she is bleeding. Germination of feathers through the skin and permanent blood wounds on the body are the attempts of alter ego to come into Nina’s reality. However, it can be considered as a cinematic metaphor and visual means used to deepen the impression of the film (not the features inherent to such mental disorder as personality split). The scenes in which Nina suffers from a variety of aberration are typical psychiatric symptoms of the hallucinatory-delusional syndrome developing in a stressful situation. The hallucinatory-delusional syndrome may accompany dissociative identity disorder. Nina’s hallucinations are shown the most brightly in the scene when she imagined that she killed her rival by the glass from the mirror. However, in reality, she hurt herself. The wound was deep, but obviously because of the shock Nina did not feel the pain and went to the final stage where danced the last part and then died. Negative attitudes towards people with mental disorders begin with prejudice. Familiarity with mental illness leads to a more enlightened view of the problem. However, the main factor is correct information. With the proper image in the movie mental disorders, stigma can be overcome. With regards to treatment, correct and incorrect depictions of disorders do not have significant effect because initially physicians are more aware of the problem. In fact, Black Swan is a story of the human disease, a split personality, and psychosis. Excellent acting shows the struggle of the individual with her second â€Å"I†. In the heavy pursuit of a dream or obsession, White Swan is suffering but fights. Black Swan also goes ahead and does not stop fighting. These swans are two â€Å"I† of one person. There are black and white sides of Nina’s personality. All her life is connected with the struggle of these two egos. Feelings and nervous breakdowns are developing in dissociative identity disorder. Nina is struggling with herself. However, she does not know who she is for sure. Identity disorder is extremely difficult for her. Eventually, the role destroys her.

Metropolis reivew - Essay Example As The Guardian observer said, Metropolis predicted the ideology of the class and race in 20th century (Bradshaw). Metropolis in a very distinct and accurate way combines social criticism, science fiction, psychological narrative and powerful love story. The combination of these factors makes it incredibly interesting to watch and impossible to ignore its huge contribution to the cinema medium and science fiction genre. Fritz Lang’s masterpiece is full of allegories, symbols and metaphors, but nevertheless it tells quite simple story though makes it in a way that makes viewer feel involved. The story tells us about the struggle between two different classes, which are represented by the love-duo of Freder and Maria who met each other by chance. The struggle takes place in the dystopian futuristic city of Metropolis which is ruled by indolent and cruel industrialists, who live in big skyscrapers and oppressed laborers who live underground. As you can see, Mr. Lang puts working class under the ground literally where they work hard so the city can stay alive, no matter what the cost is. Real millionaires of that time would be probably happy to put rebelling working class out of their minds and sight -under the ground. In the era of industrial progress when machines started taking control over the manufacture and human life in general, Metropolis turned out to be especially up-to-date. This industrial circumrotation was portrayed as horrible and fearful Molloh which can obviously be interpreted as Biblical symbol. While in real life hard-working families were hungry and op pressed with their job being taken from them and given to machines, Molloh-machine eats workers like a hungry giant or a savage beast in the movie. As Mr. Roger Ebert said, Metropolis forestalled countless symbolic and futuristic cities of the many films to come (Ebert). The City of Metropolis is a symbol of inequity and oppression because it is built with unhappiness and

College students should work part time Term Paper

College students should work part time - Term Paper Example Is part-time job important or not? In the present era, money is being important than ever. It is needed more and more nowadays. Everything is becoming so highly expensive now that the needs of many people, especially the teenagers are not being fulfilled. Even the school and college fee of many students cannot be afforded by millions of parents and those who are somehow able to bear the education expenses of their children, are not able to fulfill their other needs of life. Therefore, to meet the necessities and some of the luxuries of life, school and college students are compelled to earn for themselves. Part-time job has now become very important for school and college students. It is rather very common in the society nowadays. It may not be necessary for students to finance themselves completely through pat-time jobs, as part-time jobs certainly do not pay a very handsome amount. It is also very difficult, rather nearly impossible for students to work for many hours so as to rece ive a good amount of payment, because if they work many hours, they would not be able to give the required time to their studies and consequently will end up slipping their grades. Hence, students work for very limited hours so that they may be able to give enough attention to their studies as well s become helping hands for their parents. ... In an early age, they learn how to manage, judge and organize their priorities and their responsibility towards fulfilling them. They realize that life is not just a piece of cake and what circumstances, hurdles and troubles one has to go through to survive in this rapidly moving world. They not only work but, also have in their minds the pending homework at home which has to be submitted the very next day. This is how the students organize themselves by fulfilling both of their priorities of the job as well as the completion and submitting of their homework on time. Valuing every single penny: A job definitely teaches students to value each and every single penny. While they would not value the money earned by their parents and spend it lavishly and extravagantly, a part-time job teaches them how to value the earnings. This is because they have to work quite hard during their jobs for the sake of earning some money. They realize the fact that each and every single dollar is earned w ith a lot of hard work. Therefore, they start respecting and valuing money. Time Management: Time management is another very important factor that the school and college students learn through the part-time jobs. They attend their classes, go to their work, complete their home works and then take out some relaxation time as well to refresh their body and minds. All this is done if students know how to manage their time. Majority of the students think that part-time job is an extra burden for them along with their regular classes as well as the tasks given by their teachers to be accomplished at home. But, actually all this burden is temporary which helps the students to manage their time in a way that they may pay attention to the complete routine of their life,

CRIMINOLGICAL REVIEW OF MURDER ON A SUNDAY MORNING

CRIMINOLGICAL REVIEW OF MURDER ON A SUNDAY MORNING Murder on a Sunday morning is a documentary film based on a real life incident that occurred in Jacksonville, Florida in the May of 2000. This 111-minute movie was directed by the French documentary filmmaker Jean-Xavier de Lestrade and was originally released under the title Uncoupable ideal. It won the Oscar award for the best documentary in 2002. The film brilliantly depicts an ignominious false conviction of an innocent 15-year old for a crime he never committed, the cover-up of the real culprits behind the crime, and finally the clemency of a public defender coming to his rescue in the courtroom. The plot originated from the incident of Mary Ann Stephens, a 65-year old tourist from Georgia being shot dead by a black assailant. The police arrested the first convenient black culprit available, a black African American teenager, Brendon Butler, who was on his way to a job interview. The teen was subsequently denied the right to make his phone call or contact an attorney, interrogated mercilessly for an unreasonable amount of time, threatened, racially abused, tortured physically and psychologically, and forced to sign a false confession admitting to having committed the crime. The dead womans husband, though having caught a glimpse of the real culprit during the shootout, was forced by the police to publicly identify and proclaim Butler as the assailant. The motive behind the forceful arrest and the subsequent psychological torture of the innocent Butler was simply the preservation of the tourist trade in the state. A public defender, Pat McGuinness, however, takes up the case and defends Brendon Butler in a case that is extraordinarily riveting. The courtroom scenes enacted by McGuinness could probably be counted among the top classics of this genre. The well-written trial speaks volumes about the perils of instant justice meted out or more aptly, justice of convenience that is as common as real justice these days. A criminological analysis on why Brendon Butler was framed should take into account the facts that his residence was just about a mile from the place of the incident; he was an African-American, a member of an ethnic group historically infamous for being convicted in racial crimes and his locality being a lower-class urban one, with high crime rates. The victims husband, a white man in a state of trauma, might also have been under pressure to identify the victim with unclear images of a black man shooting his wife. The next question to be answered is about the instantaneous arrest and conviction of Brendon. Could they not have made a broader search? The answers may be obtained when one considers the fact that in Florida, tourism is a major industry. The people who earn their livelihood from this industry would definitely not want Florida to be known as a risky place to visit. The image of a family oriented place was to be associated with Florida at any cost. The police would have been under pressure to dispose off the case as quickly as possible to create an image of a strong and efficient administration. Also the fact that the victim was a tourist and the news of the murder being reported by the media might have put the police under a lot of pressure to come up with a suspect who would at least approximately match the descriptions available at that time. Another question to be answered is the gruesome way in which the teenager was tortured. It could be guessed that the officers are often puppets in the hands of their superiors. They are put under pressure to clear as many cases as quickly as possible. As per the law, as soon as an arrest is made, the case will be considered cleared notwithstanding the truth behind the crime. As far as they were concerned, the killer was caught. However, this argument does not prove the meticulousness of the police. We may also look at why the whole bunch of the police team was so unequivocal in putting the blame on Brendon and torturing him to the extreme. The incident details show that the main third degree interrogator was the son of the sheriff of the area. Hence, he might have had the unofficial authority to take decisions on the kind of interrogation and on seeing this; the others would have felt that they are only respecting their superiors authority in joining hands to torture him. The only saving grace is McGuinness, who played a major part in this case by defending Butler. Butler was fortunate enough to acquire such a savior in his time of extreme distress. Not all defenders are so gutsy or articulate. It was only because of McGuiness skills and dedication that Brendon Butler was proved to be innocent. Usually, it is seen that in such cases, the conviction of an innocent is used by the system to maintain their pride. Though there are hues of a racial kind of movie of the likes of Cry Freedom, when one sees that the main interrogator who was instrumental in making Butler confess a crime he never did is himself a black man, the similarity ends there. The basic and most convincing underlying message is that of a deep and ingrained insincerity in the US administration in matters of justice and a business-like attitude towards the commercial progress of the country which makes them place it above everything else. Obviously, there are quite a lot of unanswered questions in this episode. A more sensitive and unbiased approach to such incidents would be the first step towards molding a perfectly upright society.

Deception Point Page 105

127 The Triton fell†¦ Michael Tolland staggered to his feet on the inclined deck and peered over the anchor spool at the frayed winch cable where the Triton used to hang. Wheeling toward the stern, he scanned the water. The Triton was just now emerging from under the Goya on the current. Relieved at least to see the sub intact, Tolland eyed the hatch, wanting nothing more than to see it open up and Rachel climb out unscathed. But the hatch remained closed. Tolland wondered if maybe she had been knocked out by the violent fall. Even from the deck, Tolland could see the Triton was riding exceptionally low in the water-far below its normal diving trim waterline. It's sinking. Tolland could not imagine why, but the reason at the moment was immaterial. I have to get Rachel out. Now. As Tolland stood to dash for the edge of the deck, a shower of machine-gun fire exploded above him, sparking off the heavy anchor spool overhead. He dropped back to his knees. Shit! He peered around the spool only long enough to see Pickering on the upper deck, taking aim like a sniper. The Delta soldier had dropped his machine gun while climbing into the doomed helicopter and Pickering had apparently recovered it. Now the director had scrambled to the high ground. Trapped behind the spool, Tolland looked back toward the sinking Triton. Come on, Rachel! Get out! He waited for the hatch to open. Nothing. Looking back to the deck of the Goya, Tolland's eyes measured the open area between his position and the stern railing. Twenty feet. A long way without any cover. Tolland took a deep breath and made up his mind. Ripping off his shirt, he hurled it to his right onto the open deck. While Pickering blew the shirt full of holes, Tolland dashed left, down the inclined deck, banking toward the stern. With a wild leap he launched himself over the railing, off the back of the ship. Arcing high in the air, Tolland heard the bullets whizzing all around him and knew a single graze would make him a shark feast the instant he hit the water. Rachel Sexton felt like a wild animal trapped in a cage. She had tried the hatch again and again with no luck. She could hear a tank somewhere beneath her filling with water, and she sensed the sub gaining weight. The darkness of the ocean was inching higher up the transparent dome, a black curtain rising in reverse. Through the lower half of the glass, Rachel could see the void of the ocean beckoning like a tomb. The empty vastness beneath threatened to swallow her whole. She grabbed the hatch mechanism and tried to twist it open one more time, but it wouldn't budge. Her lungs strained now, the dank stench of excess carbon dioxide acrid in her nostrils. Through it all, one recurring thought haunted her. I'm going to die alone underwater. She scanned the Triton's control panels and levers for something that could help, but all the indicators were black. No power. She was locked in a dead steel crypt sinking toward the bottom of the sea. The gurgling in the tanks seemed to be accelerating now, and the ocean rose to within a few feet of the top of the glass. In the distance, across the endless flat expanse, a band of crimson was inching across the horizon. Morning was on its way. Rachel feared it would be the last light she ever saw. Closing her eyes to block out her impending fate, Rachel felt the terrifying childhood images rushing into her mind. Falling through the ice. Sliding underwater. Breathless. Unable to lift herself. Sinking. Her mother calling for her. â€Å"Rachel! Rachel!† A pounding on the outside of the sub jolted Rachel out of the delirium. Her eyes snapped open. â€Å"Rachel!† The voice was muffled. A ghostly face appeared against the glass, upside down, dark hair swirling. She could barely make him out in the darkness. â€Å"Michael!† Tolland surfaced, exhaling in relief to see Rachel moving inside the sub. She's alive. Tolland swam with powerful strokes to the rear of the Triton and climbed up onto the submerged engine platform. The ocean currents felt hot and leaden around him as he positioned himself to grab the circular portal screw, staying low and hoping he was out of range of Pickering's gun. The Triton's hull was almost entirely underwater now, and Tolland knew if he were going to open the hatch and pull Rachel out, he would have to hurry. He had a ten-inch draw that was diminishing fast. Once the hatch was submerged, opening it would send a torrent of seawater gushing into the Triton, trapping Rachel inside and sending the sub into a free fall to the bottom. â€Å"Now or never,† he gasped as he grabbed the hatch wheel and heaved it counterclockwise. Nothing happened. He tried again, throwing all of his force into it. Again, the hatch refused to turn. He could hear Rachel inside, on the other side of the portal. Her voice was stifled, but he sensed her terror. â€Å"I tried!† she shouted. â€Å"I couldn't turn it!† The water was lapping across the portal lid now. â€Å"Turn together!† he shouted to her. â€Å"You're clockwise in there!† He knew the dial was clearly marked. â€Å"Okay, now!† Tolland braced himself against the ballast air tanks and strained with all his energy. He could hear Rachel below him doing the same. The dial turned a half inch and ground to a dead stop. Now Tolland saw it. The portal lid was not set evenly in the aperture. Like the lid of a jar that had been placed on crooked and screwed down hard, it was stuck. Although the rubber seal was properly set, the hatch-dogs were bent, meaning the only way that door was opening was with a welding torch. As the top of the sub sank below the surface, Tolland was filled with a sudden, overwhelming dread. Rachel Sexton would not be escaping from the Triton. Two thousand feet below, the crumpled fuselage of the bomb-laden Kiowa chopper was sinking fast, a prisoner of gravity and the powerful drag of the deepwater vortex. Inside the cockpit, Delta-One's lifeless body was no longer recognizable, disfigured by the crushing pressure of the deep. As the aircraft spiraled downward, its Hellfire missiles still attached, the glowing magma dome waited on the ocean floor like a red-hot landing pad. Beneath its three-meter-thick crust, a head of boiling lava simmered at a thousand degrees Celsius, a volcano waiting to explode. 128 Tolland stood knee-deep in water on the engine box of the sinking Triton and searched his brain for some way to save Rachel. Don't let the sub sink! He looked back toward the Goya, wondering if there were any way to get a winch connected to the Triton to keep it near the surface. Impossible. It was fifty yards away now, and Pickering was standing high on the bridge like a Roman emperor with a prime seat at some bloody Colosseum spectacle. Think! Tolland told himself. Why is the sub sinking? The mechanics of sub buoyancy were painfully simple: ballast tanks pumped full of either air or water adjusted the sub's buoyancy to move it up or down in the water. Obviously, the ballast tanks were filling up. But they shouldn't be! Every sub's ballast tanks were equipped with holes both topside and underneath. The lower openings, called â€Å"flooding holes,† always remained open, while the holes on top, â€Å"vent valves,† could be opened and closed to let air escape so water would flood in. Maybe the Triton's vent valves were open for some reason? Tolland could not imagine why. He floundered across the submerged engine platform, his hands groping one of the Triton's ballast trim tanks. The vent valves were closed. But as he felt the valves, his fingers found something else. Bullet holes. Shit! The Triton had been riddled with bullets when Rachel jumped in. Tolland immediately dove down and swam beneath the sub, running his hand carefully across the Triton's more important ballast tank-the negative tank. The Brits called this tank â€Å"the down express.† The Germans called it â€Å"putting on lead shoes.† Either way, the meaning was clear. The negative tank, when filled, took the sub down.

Music Reaction Essay

Beethoven’s Symphony No. 5, Movement, 1 and Stravinsky’s Firebird Suite are two compositions that initially sound quite similar. They are both dramatic, extremely intense, and have the ability to leave a lasting impression upon listeners. There are, however, several key differences that separate the two, including expression, timbre, and overall effect. Although the melodies and general manner of the two pieces may seem alike, Symphony No. 5 is much more grand and composed while the Firebird Suite is more erratic and less sophisticated as a whole. Symphony No.5 is arguably one of the most famous compositions in the world, and begins with a melody with which most people are familiar. Within the first four notes, it is evident that the piece was written in a minor key with a respective melody. There is a vast range of notes throughout the symphony, with the high and low pitches resulting in two different effects. In many compositions, the most dramatic part of a song will typically consist of notes in higher octaves; but in Symphony No. 5, it is the lower pitches that make up the main melody and seem to be the most dramatic. By building the song around lower pitches, Beethoven has created an air of potential energy, with light runs and scales from the string sections providing the harmonies and escalating the drama of the lower notes. One of the most noticeable characteristics of the main melody line is the rhythm and repetition of the phrase. It consists of a triplet that stays on one note, and then jumps to a lower note that is sustained. As this phrase is repeated, it also starts to create the beat of the symphony, which is extremely clear. Even as the instruments add in quicker-paced scales that go up and down in the background, there is a strong and steady pace that is maintained by the melody line. With the melody line being able to stand out amongst all the other symphony parts, it develops a very bold and brooding musical expression. It is so vivid and moody, that one can picture Beethoven himself, walking briskly through the streets of Vienna while everyone else automatically clears the way for him. Symphony No. 5 has essentially became an extension of its composer, reflecting everything he was trying to express—the various components of his own personality and outlook. Beethoven also adds variation to the song through changes in tempo and dynamics. The quicker tempos tend to serve as a way of building up each musical phrase, yet are played at a fairly piano to pianissimo level. Like the drama that the lower pitches create, the parts that are played quietly also create potential energy that makes the louder, slower, and lower parts of the song that much more impactful. In terms of texture, Symphony No. 5 is surprisingly simple considering the intricacy of the notes and the way all of the instrumental parts are pieced together. There are several pauses that add tension to the song, while also eliminating too much unnecessary sound or instrumentals. This symphony, overall, has a very dark and intense timbre. It is dramatic and moody, but at a sustainable level that is not too harsh on the listeners’ ears—that is, it is relatively easy to listen to for a lengthy period of time due to the lower pitches and pianissimo parts that allow for the audience not to be overwhelmed. Stravinsky’s Firebird, similar to Beethoven’s piece, also begins with an introduction of accented notes and lower pitches. In this song, however, it is the higher notes that are accented rather than the lower pitches. The melody is also not nearly as easy to follow, as there is significantly less repetition. Even though both compositions involve similar instruments, Firebird uses many of the higher voices as the focal point of the song rather than the lower instruments. Throughout the piece, high strings, the xylophone, and even higher octaves played by the trombone can all be heard. The Firebird harmonies are also much more muddled and not necessarily played in sync with the melody line. There seems to be several different rhythms that are being played simultaneously during the louder, more dramatic sections of the song. This makes it quite difficult to find and maintain the beat of the piece, whereas Beethoven’s symphony is easier to follow. Regardless of its lack of simplicity, Firebird is just as expressive as Symphony No. 5. The significant change in tempo and dynamics create emotion within the piece, adding depth to the song. Firebird’s dynamic changes, in fact, may be even more dramatic as it ranges from pianissimo to fortissimo; and since the higher pitches are the tones being emphasized, it is much less understated than Beethoven’s piece. It is also more complex in terms of texture. Not only does the showcasing of more instruments add to the composition, but Firebird also has more measures that serve as a relief from the otherwise frantic nature of the song. While most of the piece is intense, there are bits of it that sound light-hearted and carefree. During these sections, the tempo is not always slower but there are fewer instruments overlapping each other, resulting in less chaos. Still, it is Firebird’s timbre that makes it clear how different it is from Symphony No. 5. It is bright, brilliant, and harsh, simply because of the pairing of high pitches with a loud dynamic marking and a quick tempo. Perhaps this is a clever decision by Stravinsky, trying to mimic the calls of a wild bird—shrill, shrieking, and somewhat harsh on the ears at times. When comparing the two compositions, it is clear that Stravinsky’s Firebird is more complex; but Beethoven’s Symphony No. 5 is much more composed overall. It is not as aggressive in terms of loud, shrieking high notes, but rather understated and intense. This also evokes more emotion out of the audience, as it plays on the darkness and moodiness of Beethoven’s personality. Firebird is undoubtedly entertaining and a complicated work of art; but when it comes to which piece is easier to listen to and which makes more sense upon first impression, it is surpassed by Symphony No. 5.
