Nucleosynthesis essays

Nucleosynthesis essays The "big bang" which created the universe, only created the elements Hydrogen (H) and Helium (He) and possibly a very small amount of Lithium (Li). However, a glance at the periodic table of the elements shows that today (some 15 billion years after the big bang) there are at least 108 known elements. Every atom of every element heavier than Li has been produced since the big bang! The "factories" which make these elements are stars. "Nucleosynthesis" or the synthesis of nuclei, is the process by which stars (which start out consisting mostly of H and He) produce all other elements. The key is nuclear fusion, in which small nuclei are joined together to form a larger nucleus. (This contrasts with nuclear fission, in which a large nucleus breaks apart to form two smaller nuclei). Fusion requires an extremely large amount of energy (see fig. 1), and can typically only take place in the centers of stars. a) Low energy proton is strongly repelled by the 7Be nucleus.b) High energy proton moves so fast that it can strike the 7Be nucleus. Once the proton touches the nucleus, it has a chance to stick. If the proton sticks, the 7Be becomes a 8B nucleus.c) 8B is radioactive and changes into 8Be plus a positron (b+) and a neutrino (n). 8Be is itself radioactive, and almost immediately breaks into two 4He nuclei. Protons repel each other. This repulsion becomes stronger as the protons get closer together (just like when you try to stick two magnets together north to north, or south to south. Try this! As you push the magnets closer together, it becomes harder to do). However, if the protons can actually touch each other, they have a chance to stick together! This is because of the "strong nuclear force" which attracts nucleons (protons or neutrons) together, and is much stronger (at close range) than the "electromagnetic force" repulsion that makes protons repel other protons. (Magnets do not do this: two like poles wi...

Essay on Bipolar Disorder

Essay on Bipolar Disorder According to the National Institution of Mental Habits, bipolar disorder is characterized by extreme mood changes, from manic episodes of intense energy, followed by extreme lows of depression. Quite a few of the history’s best artists, entertainers and athletes and the like have or have had Bipolar Disorder – whether diagnosed or not. This includes crooner Frank Sinatra, 1960s icon Jimi Hendrix, ’90s rocker Curt Kobain, painter Vincent Van Gogh, tons of writers, and even actress Catherine Zeta-Jones, among too many others. Sometimes called â€Å"Manic Depression,† Bipolar Disorder affects 2.5 percent of the U.S. population. It is characterized by extreme mood changes, from manic episodes of intense energy, followed by extreme lows of depression, according to the National Institution of Mental Habits. Bipolar Disorder is difficult to diagnose, even to experts, because there are so many different varieties of Bipolar Disorder and Depression. Reasons of Bipolar Disorder Many factors can be attributed to the reason a person experiences Bipolar Disorder. It can be due to their genetics, as in how they may have inherited from their parents the gene for Bipolar Disorder. It could be brought on by drug and alcohol abuse and addiction; it is a much-known fact that substance abuse is very common among people with Bipolar Disorder, the reasons for which are unclear. However, it is speculated that people with Bipolar Disorder may treat their symptoms with alcohol or drugs. It is also known that substance abuse can trigger, or even prolong, mental illness, including mood disorders. Naturally, medications exist for Bipolar Disorder, and they have been known to help alter a person’s brain chemistry so that their mood is balanced and steady. After a person is diagnosed with Bipolar Disorder, they are most always given medication to combat the intense symptoms. RELIEVING STUDENTS SCHOOL-RELATED STRESS However, lifestyle choices can also potentially help a person manage their mental illness or mood disorder. This extends to drinking habits and drug-taking habits, as said before, but stress, diet, exercise habits and overall health play a crucial role, too. Moderation and self-discipline are always key. Exercise has a way of balancing the firing of neurotransmitters in the brain, which play a crucial role in mood, behavior and cognition and happiness. It is a proven fact that exercise and physical health are fundamental to good mental health, as well, in part because it helps relieve stress and tension and it also encourages the body to work properly and effectively. How to Deal with Mood  Disorder? One of the scariest things about any mood disorder is the way it becomes insurmountable to deal with and tackle. In other words, some people experience horrific Bipolar episodes and fear they will have to deal with the uncertainty and unpredictability of it for the rest of their lives. It affects every single aspect of one’s life. Unfortunately, this all too often tricks people into thinking they are better off committing suicide, ending their life, the pain, the depression. This is because the person with Bipolar Disorder experiences a high so high that they feel they can do anything, become a better person, be successful and happy and productive and wealthy. They get ideas and missions, create objectives, and they get powerfully motivated to do something. However, this high, the manic state, can directly follow a Depression so crippling that they feel the Manic state they just experienced was mostly just to tease them – that they could never be happy or at least not h appy for too long. To conclude, Bipolar Disorder exists and it’s an issue worth paying attention to. It is something that affects people from all walks of life, cultures, professions, philosophies – and it affects various – if not all – aspects of their life, as well, almost always in a detrimental way. It can keep a person from sleeping well at night, from eating and interacting with people, from doing things they enjoy, even things they have to do – like going to work and other responsibilities. Even simple things like doing laundry can be a struggle for people with Bipolar Disorder or with any variation of Depression. What is most tragic about Bipolar Disorder is the fact that it can occur suddenly and without any warning – it just happens. Nothing, in particular, may trigger it. Bipolar Disorder doesn’t discriminate by wealth, ethnicity, and religious creed. But it is a problem all over the world – and it is just as serious as cancer is.

General Psychology - Essay Example Focusing on ways to prevent sleep deprivation and moving toward practices of healthy sleep can assist one with mental, physical and emotional activities through daily life. The importance of sleep begins with the stages of sleep which occur as well as how this affects different stages that one goes through with the activities in the mind. The main cause of sleep is based on wave patterns in your mind that balance the sleeping and waking systems. When the wave patterns slow down, it communicates to the mind that the body should also move slower, which leads to sleep. The result is a slower pattern of brain waves which is required for certain periods of time each night. There are four stages of sleep that are a part of the cycle. Stage 1 is a light sleep where the heart rat slows down and breathing is irregular. Relaxation and alpha waves, a slower brainwave, are the two features of stage 1 sleep. Stage 2 leads to a drop of temperature and spindles of brainwave activity. Stage 3 leads to delta waves in the brain which are larger and slower than other brainwaves. Stage 4 is deep sleep and is typically reached after 1 hour. This is a slow wave of delta and can lead to a lack of consciousness from the brain (Coon, Mitterer, 186). The stages associated with sleeping are an indicator of why sleep is needed as well as what occurs when one gets enough sleep. If one doesn’t receive enough of stage 4 sleep, it can become detrimental to health, both physically and mentally. The body requires the brainwaves to move at a slower pace for a given period of time and to begin to change and relax for given periods of time. Learning, memory and functions that are associated with mental capacity aren’t able to function at full capacity if one doesn’t receive enough sleep. The complications occur with neuronal

Effectiveness of Public Private Partnerships Cooperation Between Essay

Effectiveness of Public Private Partnerships Cooperation Between Business and The Government - Essay Example In such sort of relationship, there is a co-dependency of both the parties involved. The responsibility of government is of primal importance as it is solely the duty of government to provide the private sector with public services. Hence, governments are making use of such partnerships thereby getting massive financial benefits from public private partnerships. Apart from providing value for money, public private partnerships are also useful for providing newly formulated designs, advanced public services, and an excessively rapid process of construction. Some governments are facing alleged accusations of using public private partnership for political motives. It is a substantial fact that public private partnership function properly under the mutual affinity between the private and public sector thereby making pp services as non-privatized and non-nationalized services. In addition to it, such partnerships offer mutual dependency upon each other, which allows them to attain remarka ble results. The core issue related to public private partnership is budgeting for it entirely depends upon the financing of the private group. For instance, if finances and cost of the project are the responsibilities of the private sector, the government does not feel the necessity to take control of matters related to finance. However, when funds are un-available, government feels the need to meet the financial requirement by imposing public taxes. Trans-European Network for transport is proposed to alleviate problems related to financing in public private partnership. This network is constructed to meet the requirements of recession and inflation. As with the descending economical condition of many countries,...This paper outlines the growing importance of successful cooperation between public and private sector in form of public private partnerships in the world today. The well designed project not only helps the parties to stay committed to their work but it also offers them a scope of improvement than the previous project, the risk factors are reduced, reliability is higher and the efficiency of the project is also higher. One of the biggest advantage of public private partnership is that in case of any mishap or loss in the project; the expenses are shared by both the parties involved. The risks of bigger losses are minimized. Another significant advantage of these partnerships is achieved by the fact that it is essentially duty of the government to decide the user charges on which a normal person can use the infrastructure. Due to the current economic recession, the significance of public-private partnership has been increased as now governments are facing grave economical pressure and private-public partnership has become a strong medium to facilitate the building of infrastructure because the investors have been encouraged to invest in the building of infrastructure that may include hospitals, re-creational parks, educational institutions, etc. Apart from providing value for money, public private partnerships are also useful for providing newly formulated designs, advanced public services, and an excessively rapid process of construction. There are many forms of public private partnerships depending upon the business and finance controller of the project as sometimes it is solely in control of the public sector or in control of the private sector the other times.

Dark and gothic atmosphere Essay

In this essay I will show how Mary Shelley manipulates the reader’s view of the monster throughout her novel â€Å"Frankenstein.† I will show that Shelley creates many different impressions on the reader, through various methods, to change their opinion throughout the book.  Ã¢â‚¬Å"Frankenstein† is a romantic gothic horror novel written in 1818 by a young woman named Mary Shelley. It includes the classic gothic themes of romance, horror, religion and good and evil. â€Å"Frankenstein†, however, is centred on a issue still debated today; whether trying to change life is playing God and if it will lead to dire consequences. At the time of writing Mary Shelley was 16, the wife of Percy Shelley and staying in the Swiss Alps with Lord Byron and her husband. One of the more classic methods Shelley uses to manipulate her readers is setting. In chapter 5 the setting gives a dark and gothic atmosphere, which tells the reader that the monster is horrifying and to be feared. â€Å"One in the morning; the rain pattered dismally against the panes, and my candle was nearly burnt out.† This quote is giving the reader the idea of isolation; something surreptitious and forbidden. Mary Shelley does this by using a classic gothic horror setting; the night which traditionally implies evil, secrecy and darkness, the bad weather, used to make everything more dank and dismal, and the burnt down candle, a symbol of long hours of frenzied work and manic concentration. This setting also reflects badly on Frankenstein’s character; the middle of a stormy night when most people would be in bed and he is up, furtively completing a long held ambition. The burnt down candle image heightens this idea but also adds the concept that Frankenstein himself may be close to burning out. The candle is used as a metaphor for his own exhaustion. This type of setting shows the reader that Frankenstein is doing something secretly, something offensive to society. This casts a negative shadow on his character. The setting is also used to put a negative slur on the monster and just about everything else in the scene. The setting is used to make everything worse. The strange hour of the night and turbulent weather show the reader that the monster must be weird and unnatural to be kept away from normal people. Overall the main effect of this setting is to make all the ideas Mary Shelley presents to her readers in this chapter seem twisted and dangerous. Another thing which Mary Shelley uses to influence the reader’s opinion of the monster is its appearance. We are introduced to the living monster in chapter 5 and this is where most of the description concerning its â€Å"horrid† appearance is used. The monster is repulsive and gruesome, which is described in horrifying detail, causing the reader to make negative judgements on its character. In describing the monster Shelley also uses the reference of â€Å"Dante†. This comparison introduces a religious element; in playing God, Frankenstein has produced something worse than can be found in Hell. This also reinforces the unnatural image. This is continued with the idea that the monster has not turned out the way Frankenstein expected. â€Å"Beautiful! Great God! His yellow skin scarcely covered the work of muscles and arteries beneath†¦Ã¢â‚¬  The whole vivid description centres on the unnatural and freakish, especially the way the monster’s innards are described as visible through the monster’s sallow skin. This creates a dramatic image in the readers mind as something human shaped but ultimately wrong, different and scary, more animal than human. The monster is also described as having â€Å"watery eyes† which make us think of illness, or perhaps, in the case of the monster, crying. This idea makes the monster seem all the more wretched and repulsive. Mary Shelley also uses the reaction of Victor Frankenstein to prejudice her readers against the monster in chapter 5. â€Å"†¦the beauty of the dream vanished, and breathless horror and disgust filled my heart.† The inventor turns against his creation immediately after giving it life. He takes no responsibility for the monster’s well being though he is the closest thing to a father the monster could have. He runs from his duty and breaks down, delirious with the shock of losing his dream and realising that he has done an evil deed. This adds to the fear felt by the reader; if even it’s creator cannot stand the monster, how evil would a stranger find it? The way Frankenstein turns against the monster the moment it comes to life signals to the reader that this is the moment when the sin is committed. Giving life is going against God so this is where all the negativity in this chapter, and in most of the book starts. The last influence on our opinion of the monster I will look at in chapter 5 is the monster’s own words and actions. In this chapter they are deliberately given a double meaning; animal, or baby? â€Å"His jaws opened, and he muttered some inarticulate sounds, while a grin wrinkled his cheeks.† This quote shows the monster as incoherent, whether due to a lack of intelligence or experience is unclear at this point. However the monster has, in effect, just been born and the behaviours Shelley describes are very similar to young children not quite in control of their movements, trying to pick up or chew on everything they find. When these movements are applied to the monster Shelley describes they become intimidating and threatening which gives the reader an even worse impression of the monster, when in reality it is just a scared child who has been called into the world and then rejected within minutes. Frankenstein is the first living creature the monster sets eyes on. This means that in its view Frankenstein is its father. This means that the monster reaches out to him for comfort and shelter. â€Å"†¦one hand was stretched out,† This quote shows the monster reaching for Frankenstein. However Shelley deliberately leaves the action open for interpretation as an animal attack to reinforce the overall impression received by the reader in this chapter that the monster is an ugly, evil, dangerous, horrifying animal. There are a lot of contrasts between chapters 5 and 10. The first is the setting which becomes a lot more dangerous and inaccessible in chapter 10. The setting is first portrayed in this chapter as enormous and amazing, as yet untouched by humans. â€Å"Solemn silence of this glorious presence-chamber of imperial nature was broken only by the brawling waves or the fall of some vast fragment.† This quote shows why Frankenstein has come to this place; he wants peace and isolation, and to think about more than just his own personal tragedy. â€Å"They elevated me from all little ness of feeling, and although they did not remove my grief, they subdued and tranquillized it.† The language used to describe the setting is more elaborate in this chapter, which reflects the increased grandeur of the scene. This is done to create a sense of awe from the reader and to show them how isolated the setting is, which affects their perception of the monster when he is introduced to the c hapter.

The United States has many political parties such as Libertarian party, Green party and Constitution party to name a few, yet none are as major as the Republican and Democratic Party. Both have different political views on issues that affect many Americans today. These parties are divided in many, ways and they both have special interests and want to make the United States a better country. Don’t waste time! Our writers will create an original "Comparison of two political parties" essay for you Create order These two major political parties, Republican and Democratic have different views and stances on issues that affect millions of American citizens, this includes political issues such as: abortion, gun control, and immigration, though they want whats best for the United States, its up to the decision of the people to vote what they want for this country. Abortion is a major issue that affect many women in the United States. Both parties have different views on this issue and due to this many laws are created to either cease or support the issue of abortion. The Republicans stance on abortion is that they believe that due to the Fourteenth Amendment in the Declaration of Independence an unborn child has the same rights as any other human being. Republicans refuse the use of public revenue that benefit the funding for abortion, and the organizations that perform it. Yet, the Democratic party strongly support the rights for women to have an abortion. Supporting Woe v. Wade, the Democrats want all women to have every right to have an abortion, not wanting the politicians or the government to getting in the way of it. Democrats would help fund programs, such as plan parenthood who perform abortions on women, and other programs which help educate women to not have unintentional pregnancies and provide health care for women who decide to ha ve a child. Today, Republican President Donald Trump strongly opposes abortion and has already signed an executive order that denies the U.S. funding of foreign organizations that perform abortions around the world. Most likely with a new conservative Supreme Court Judge Brett Kavanaugh, the future looks grimmer for the right of women to have and abortion. Gun control is a major issue in the United States, about 96 Americans every day are killed by guns. Both Republicans and Democrats support the prevention of people who have a mental illness to purchase guns. Where they disagree on is factors in gun violence and concealed guns, both parties disagree on how legally obtained guns play a role in gun violence. Republicans believe that if more Americans owned guns there would be less crime; however, the Democrats believe that there will be more crime if more Americans owned guns. Democrats say that if it was harder to legally purchase a gun, then there would be less mass shootings. Many Republicans say that it would make no difference if guns are tougher to purchase or not. Much of America is divided on gun control, many believe that it should be Congress top priority to make stricter gun laws. After, the Parkland shooting happened back in February, killing 17 people and injuring 17 others, the students of Stoneman Douglas High School prot ested to make stricter gun laws, many Americans believe that it had somewhat a minor impact. Though, it had a minor impact Congress only passed a bill that would train school officials and local authorities to be able to deal with a mental health crisis. Gun control in the U.S. is a major issue and there is need for stricter laws, yet as a divided nation many people believe otherwise. Immigration today in America is a hot topic. Republicans and Democrats have different opinions on immigration, and they both take different actions to deal with this issue. Democrats view on immigration is that the United States is a diverse country that is based on immigration and the country should continue to support current and future immigrants. The Republicans support a stronger border and for those people who are here illegally will be detained, sent to their country of origin. When Barack Obama was president, he and many other Democrats fought for the Dream Act, this act would allow people who were brought here illegally as children by their parents to become a citizens. Today with Republican Donald Trump and his promise to secure our southern border with a BIG wall, many people are divided on this issue, the reason is that the wall will cost upwards of 18 billion to build and millions to maintain a year. Democrats are against this because of all the money the U.S. is going to use, and it goes against what they believe in. As a nation divided from an issue such as immigration, the United States is a country of immigrants and built by immigrants. The United States is a country where Republicans and Democrats are the two of biggest and most influential parties. Both have different views on issues that this country has, and they both have different solutions for each in their own way. Abortion is an issue that plagued the U.S. for many years with Roe v. Wade back in 1973 and will continue with Republicans and Democrats fighting for what they believe in. Gun control is an issue that the U.S. cant seem to regulate, the country is seeing more gun violence in our schools and in public places. Gun control is an issue where people are most divided on and its up to lawmakers to prevent gun violence with more laws and regulations on guns. Immigration is the most recent issue in the past decade with more and more immigrants coming across the border illegally, and these parties see it, while the Democrats believe that this country is built by immigrants and believe that they should become citizens. The opposing party believe that immigra nts should go back to their country and secure a border in which no illegal person should cross. The country today with a president whose approval rating is 42.2% and with many people not agreeing with his views. Our country today is the most divided it has ever been.
