manic depression Essay -- essays research papers

MANIC DEPRESSION Estimates say that about 2 and a half million Americans suffer from manic depressive illness. Also called bipolar disorder, this mental illness involves episodes in which a persons mood alternates between extreme mania and depression. A person may experience pressure and racing thoughts and speech, and often uncontrolled reckless behavior. Two thirds of those who suffer from bipolar illness have numerous episodes of recurrences of alternating phases. Most people suffering from manic depressive illness experience extreme cases of up and Dow emotion. Studies say manic depression is one of the most understudied psychiatric illnesses. Bipolar disorder is much less common than depression. atleast 8 percent of people experience depression within their lives. bipolar disorder affects men and women almost equally, and is most common amongst upper economic classes. 15 percent of people with bipolar disorder commit suicide. research shows that highly creative people such as artists, composers , writers, and poets, show usually high rates of bipolar disorder. Their periods of mania is said to fuel their creativity. Bipolar disorder usually begins in a persons late teens early twenties. Men usually experience mania as the first mood episode, where as women usually experience depression first. episodes of mania and depression usually last from several weeks to several months. In most cases swings between mania and depression occur within days. In other cases a person may experience major depression and minor mania. Mania and depression may also follow patterns of seasons. Mania in the winter and fall and depression in summer and spring. People suffering from bipolar disorder feel indifferent to work and have no desire to do anything constructive. They think slow, concentrate poorly, feel tired, and experience changes, usually an increase in appetite and sleep. They often feel a sense of worthlessness and helplessness. In some cases a person may feel pessimistic about the future and may attempt suicide. a patient may all experience delusions and hallucinations. In the manic phase people feel intensely and inappropriately happy, self important and irritable. During this state a person becomes highly energized and sleeps less, talking in rapid fire speech often going off in all directions. They have inflated confidence and unfounded self esteem. Man... ... symptoms become extreme or dangerous. experts say causes can be fights between spouses or loss of sleep. A patient most likely will still suffer from some symptoms even if they follow the exact order of medicine. This illness has no cure. Doctors also have not figured out what causes bipolar disorder. Allot of patients find comfort in talking to other patients about their illness. This allows the patients to find a common bond with another person. Giving the patient the comfort of knowing someone else is going through the same thing if not worse. hospitals offer many support groups for manic depressive people. Stress is said to be the biggest cause of mania and depression occurances. Therapy is supposed to reduce a persons feeling of stress. Manic depression research as come a long way since it was first discovered. It still remains though one of the most understudied psychiatric disorders. Millions of people a year suffer from this diease. It can result in suicide, drug abuse, and unprotected sex. This illness deserves more attention then it is receiving. I feel we as a nation should address the on going rise of suicides as a cause of one form or another of manic depression.

Children and Screen Time Essay

Every parent wants nothing more then their child to succeed. They want their child to develop and learn with out struggle. In this day in age we have access to so many devices that can help contribute to a child’s success. Many will argue that a device such as a I-pad or mobile device will hinder ones learning. I feel the exact opposite will occur, and the child will gain knowledge. Children develop and learn so much at a very young age. They absorb everything they see and hear. They best learn through touch, sight, and sound. Using a device such as a touch I-pad, or I-phone a child can interact on their level. There are so many Apps available for children of all ages. They will help a child develop at their capability and speed, while learning. I feel they will absorb more knowledge with a educational hands on device rather then TV. Children have to interact and use their brains in order for the App to work. Placing a child in front of a TV to just sit and learn, they do not get the same hands on experience. There will be those arguing that placing a phone or tablet in a child’s arms will cause harm. I do not see that being true, in this day in age we use App’s for everything. Rather at the grocery store, banking, or even schools, most teach with touch devices. I feel that helping your child learn with a hands free device, will only help them in the future.

Understanding Quantum Optics

Quantum optics is a field of quantum physics that deals specifically with the interaction of photons with matter. The study of individual photons is crucial to understanding the behavior of electromagnetic waves as a whole. To clarify exactly what this means, the word quantum refers to the smallest amount of any physical entity that can interact with another entity. Quantum physics, therefore, deals with the smallest particles; these are incredibly tiny sub-atomic particles which behave in unique ways. The word optics, in physics, refers to the study of light. Photons are the smallest particles of light (though it is important to know that photons can behave as both particles and waves). Development of Quantum Optics and the Photon Theory of Light The theory that light moved in discrete bundles (i.e. photons) was presented in Max Plancks 1900 paper on the ultraviolet catastrophe in black body radiation. In 1905, Einstein expanded on these principles in his explanation of the photoelectric effect to define the photon theory of light. Quantum physics developed through the first half of the twentieth century largely through work on our understanding of how photons and matter interact and inter-relate. This was viewed, however, as a study of the matter involved more than the light involved. In 1953, the maser was developed (which emitted coherent microwaves) and in 1960 the laser (which emitted coherent light). As the property of the light involved in these devices became more important, quantum optics began being used as the term for this specialized field of study. Findings Quantum optics (and quantum physics as a whole) views electromagnetic radiation as traveling in the form of both a wave and a particle at the same time. This phenomenon is called wave-particle duality. The most common explanation of how this works is that the photons move in a stream of particles, but the overall behavior of those particles is determined by a quantum wave function that determines the probability of the particles being in a given location at a given time. Taking findings from quantum electrodynamics (QED), it is also possible to interpret quantum optics in the form of the creation and annihilation of photons, described by field operators. This approach allows the use of certain statistical approaches that are useful in analyzing the behavior of light, although whether it represents what is physically taking place is a matter of some debate (although most people view it as just a useful mathematical model). Applications Lasers (and masers) are the most obvious application of quantum optics. Light emitted from these devices is in a coherent state, which means the light closely resembles a classical sinusoidal wave. In this coherent state, the quantum mechanical wave function (and thus the quantum mechanical uncertainty) is distributed equally. The light emitted from a laser is, therefore, highly ordered, and generally limited to essentially the same energy state (and thus the same frequency wavelength).

Evolution of Dinosaurs to Modern Animals

Dinosaurs didnt spring suddenly into existence two hundred million years ago, huge, toothy, and hungry for grub. Like all living things, they evolved, slowly and gradually, according to the rules of Darwinian selection and adaptation, from previously existing creatures—in this case, a family of primitive reptiles known as archosaurs (ruling lizards). On the face of it, archosaurs werent all that different from the dinosaurs that succeeded them. However, these Triassic reptiles were much smaller than later dinosaurs, and they possessed certain characteristic features that set them apart from their more famous descendants (most notably, the lack of a locked-in posture for their front and hind limbs). Paleontologists may even have identified the single genus of archosaur from which all dinosaurs evolved: Lagosuchus (Greek for rabbit crocodile), a quick, tiny reptile that scurried across the forests of early Triassic South America, and that sometimes goes by the name Marasuchus. Evolution During the Triassic Period Confusing matters somewhat, the archosaurs of the middle to late Triassic period didnt only give rise to dinosaurs. Isolated populations of these ruling reptiles also spawned the very first pterosaurs and crocodiles. For as much as 20 million years, in fact, the part of the Pangean supercontinent corresponding to modern-day South America was thick with two-legged archosaurs, two-legged dinosaurs, and even two-legged crocodiles—and even  experienced paleontologists sometimes have trouble distinguishing between the fossil specimens of these three families! Experts are unsure whether the archosaurs from which the dinosaurs descended coexisted with the therapsids (mammal-like reptiles) of the late Permian period, or whether they appeared on the scene after the Permian/Triassic Extinction Event 250 million years ago, a geologic upheaval that killed about three-quarters of all land-dwelling animals on earth. From the perspective of dinosaur evolution, though, this may be a distinction without a difference. Whats clear is that dinosaurs gained the upper hand by the start of the Jurassic period.  (By the way, you may be surprised to learn that therapsids spawned the first mammals around the same time, the late Triassic period, as archosaurs spawned the first dinosaurs.) The First Dinosaurs Once you climb your way out of late Triassic South America, the path of dinosaur evolution comes into much sharper focus, as the very first dinosaurs slowly radiated into the sauropods, tyrannosaurs, and raptors we all know and love today. The best current candidate for the first true dinosaur is the South American Eoraptor, a nimble, two-legged meat-eater akin to the slightly later Coelophysis of North America. Eoraptor and its ilk survived by eating the smaller crocodiles, archosaurs, and proto-mammals of its lush forest environment, and may have hunted by night. The next important event in dinosaur evolution, after the appearance of Eoraptor, was the split between saurischian (lizard-hipped) and ornithischian (bird-hipped) dinosaurs, which transpired just before the start of the Jurassic period. The first ornithischian dinosaur (a good candidate is Pisanosaurus) was the direct descendant of the vast bulk of the plant-eating dinosaurs of the Mesozoic Era, including ceratopsians, hadrosaurs, and ornithopods. Saurischians, meanwhile, split into two main families: theropods (the meat-eating dinosaurs, including tyrannosaurs and raptors) and prosauropods (the slender, bipedal, plant-eating dinosaurs that later evolved into gigantic sauropods and titanosaurs). A good candidate for the first prosauropod, or sauropodomorph, is Panphagia, the name of which is Greek for eats everything. Ongoing Dinosaur Evolution Once these major dinosaur families were established, around the start of the Jurassic period, evolution continued to take its natural course. But according to recent research, the pace of dinosaur adaptation  slowed down drastically during the later Cretaceous period, when dinosaurs were more rigidly locked into existing families and their rates of speciation and diversification slowed. The corresponding lack of diversity may have made dinosaurs ripe pickings for the K/T Extinction Event  when a meteor impact decimated planetary food supplies. Ironically, just the way the Permian/Triassic Extinction Event paved the way for the rise of dinosaurs, the K/T Extinction cleared the way for the rise of mammals—which had existed alongside the dinosaurs all along, in small, quivering, mouse-like packages.

Can Hybrid Cars Reduce the Dependency on Fossil Fuels Free Essays

Can Hybrid Cars Reduce The Dependency On Fossil Fuels? I am going to talk about hybrid cars and can they reduce the dependency on fossil fuels. The hybrid cars manufactures that I’m going to use is Toyota, Honda Can hybrid cars reduce the dependency on fossil fuels? Hybrid cars can reduce the dependency of fossil fuels because it would stand between the consuming world and its gas guzzling cars by replacing them with fuel efficient hybrid cars. Hybrid cars have lower level of gasoline consumption, therefore environmentally friendly causing less pollution then gasoline- powered cars. We will write a custom essay sample on Can Hybrid Cars Reduce the Dependency on Fossil Fuels or any similar topic only for you Order Now They beat electric cars by a long run which gives about 50 – 100 miles in-between    battery charges that require many hours to fully charge up. Even then electric cars made it possible to have development towards hybrid cars. Toyota Prius was the first passenger car with hybrid technology which was brought forth in Japan in 1997. Toyota and Honda introduced hybrid cars to the American markets in the beginning of 1999. Hybrid car are a combination of gasoline and electric powered car. Hybrid cars consist of a internal combustion engine that is small and fuel efficient. The hybrid cars internal combustion engine is assisted by the electric motor when the car is accelerating. The electric motor is generated by rechargeable batteries that automatically recharges when the car is being driven. The Toyota and Honda hybrids work and operate in a similar manner. The engine for gasoline    is smaller then the regular conventional cars. Essentially Toyota and Honda hybrids fellow the same concepts as most hybrids, It receives backup energy from the electric motor gets energy that the motor needs to help the engine when accelerating there for not consuming a large quantity of gasoline. However the Toyota and Honda hybrids also have a different source of generating energy. When the driver hits his or her breaks the kinetic energy created by the heat and friction of the break is claimed by the electric motor and stored in the batteries. Then it comes to transmissions most hybrids and conventional cars are alike. However the Prius has an additional generator and a circle gear complex to make a controlled, yet continues variable transmission, taking away the need for any conventional manual or automatic transmission which use up unnecessary amount of energy that go to waste. The early hybrid gave about fifty to sixty miles per gallon. The exhaust pollution was almost eliminated and also the acceleration of the hybrids were far bettered then the non-hybrid cars. By 2008 almost all car manufactures offered hybrid model cars along with a few sports hybrid cars. Many of the sports hybrid cars however did not give as much mileage and more expensive then the conventional cars. The federal government offers a good amount of tax credits to purchaser of hybrid cars. The key to the future of hybrid–car development lies in battery technology. The early hybrids resembled the old conventional electrical system that ran with lead-acid batteries. These lead-acid batteries were bulky and carried a heavy weight and were a major factor in holding back the development of hybrid and electric cars. Most of the current hybrids contain nickel metal hydride batteries, which are smaller, lighter, and more powerful. However the cost is a big factor in this development. Nonetheless most car manufacturers are focusing on lithium-ion batteries. The way to using lithium-ion batteries on hybrid cars has opened up promise the development to a generation of new hybrid vehicles. This development of lithium-ion batteries on hybrid cars allows the capability of the cars to be plug in hybrids. The car will have extended distance without the help of their gasoline engine. This development has made hybrid cars more affordable. In the big picture if our country in whole used more hybrid cars in our day to day life it would be just that much less gasoline we would not me using. If there if do get a hybrid car in the long run you a creating a clean friendly environment and saving less trips to the gas pumps, which mean more money in your pockets. Who doesn’t want that with all the rising high gas prices and our economic condition? We need to put more hybrid cars on the road so we are use less gas and better our economy as a whole.

Business Model Idea for Business Market - MyAssignmenthelp.com

Question: Discuss about theBusiness Model Ideafor Business Market. Answer: Introduction Starting up business has become a latest trend among the youth. Everyone wants to do something on their own rather than doing jobs in other companies. Australian business market has observed huge growth in online retail sector in the past 2 years. Statistics shows that 80% of the Australian internet users have made online purchase last year. The demand of online retail store has grown huge in the recent years. So it is definitely a great business idea to start an online retail store. It is also to be noted that more than 75% of Australian household have access to internet (Sohaib Kang, 2014). Most importantly the busy daily life schedule has made it extremely difficult for the people to find some time for some shopping for near and dear ones. Online shopping gives those people the perfect opportunity to buy their desired product without spending any extra time in store. The most essential business components that the business idea needs are Revenue Model This model is basically related to the strategies and process that the company will apply in order to generate revenues from the market. It completely depends on what are the products that the online retail store will sell and how the customer will accept the products. It is all about the positioning, value propositioning. As opined by Verma, et al. (2016), every business should be unique and innovative. The business has to be designed in that way. Suppose anyone wants to open an online retail store then they have to make sure that whatever service or product they are selling has to be of top quality. People should provide positive feedback for the product. This is the only way through which the business can bloom. All these components are extremely essential for the success of the business. Gross Margin Components This is the most important components as it is of no use for starting a business if the owner does not have any idea of how much profit the business will make. This is extremely crucial for the company. The online retail markets have a huge demand in the market. So the pricing factor is very essential in order to draw more and more customers. Porters cost leadership strategy is a very good example for this. The more discount the company will give the more profit will get generated by the company. But in all these it has to be made sure that the companies do not face any kind of loss. Operating Components The maintenance of website, shipping cost, tie up with some online retail market leaders and maintaining a SEO team is some of the most basic start up expenses for any online retail company. Every company has to ensure that the payment gateway is authentic and secure so that money transactions can be done properly. All these are main operating costs. The company has to make sure that all these are properly maintained so the employees working gets satisfied with whatever the salary that they are receiving. Financial Components Majority of the startup business gets doomed due to lack of capital. For starting up a business one has to make sure that they are backed up with their proper fundraiser. Fundraiser can be any banks providing loans. Without the help of external resources it is impossible for any start up business to flourish (Verma, Sharma Sheth, 2016). Security Components Online stores have become hugely popular in the market in the recent times. Still some section of the populations gets panicked and afraid while spending money due to security issue. They feel that the company might steal their money and their account can also get hacked. This is why the paypal system has the transaction procedure has to be proper so that such misconception can easily be avoided. The more people will get comfortable in paying the money the more sell will (Shrier, Canale Pentland, 2016). . Conclusion In this report online retailing has been selected as the business idea due to its huge success in Australia and also all over the world. The more the days are passing the demand for such online services are also getting increased. Now for every business a proper revenue model has to be followed and along with that revenue model some of the major business components has to be taken care off without which a business can never become successful. This report suggests that in the current marketing scenario Online shopping is definitely one of the great business ideas. Reference List Shrier, D., Canale, G., Pentland, A. (2016).
