...was seven years old, he moved to Russia with the rest of his family to be with his father, who was there as an explosive maker. While there, his parents had gotten Alfred a private tutor and very quickly he mastered chemistry an became fluent in four other languages, aside from Swedish. Nobel’s father owned a guns and arms factory and after working there, Nobel became curious, which led him to studying more deeply into the field of chemistry (and explosives). He spent a year studying in Paris and five years in the U.S. before he moved back to Russia. Nobel’s greatest accomplishment was the discovery of dynamite in 1867. The reason he created it was because there was an explosion that killed his younger brother and he wanted to develop a safer alternative explosive. Nobel was patented with the mixture of nitroglycerin and an absorbent substance, and then coined it dynamite. Nobel earned a great deal of money from his discovery, but he put it to good use by creating the Nobel Prize. The Noble Prize is defined as any of the six international prizes awarded annually for outstanding work in physics, chemistry, medicine, literature, economics, and the promotion of peace. The first one was awarded in 1901 and then annually awarded on December 10th, in honor of his death. There have been a few controversies regarding Nobel. One of which has to do with the Nobel Prize. It is supposed to be awarded for excellence in an area of expertise, but...

...Nitro-glycerine, with the molecular formula C3H5(ONO2)3, has a high nitrogen content (18.5 percent) and contains sufficient oxygen atoms to oxidize the carbon and hydrogen atoms while nitrogen is being liberated, so that it is one of the most powerful explosives used. Nitro-glycerine is extremely sensitive to shock and to rapid heating; it begins to decompose at 50 to 60 °C and explodes at 218 °C. nitro-glycerine has a high freezing point (13 °) and the solid is even more shock-sensitive than the liquid. This disadvantage is overcome by using mixtures of nitro-glycerine with other oxynitrates. A mixture of nitro-glycerine and ethylene glycol dinitrate freezes at −29 °C. It was first prepared in 1846 by the Italian chemist Ascanio Sobrero (1812–1888), who nitrated glycerol using a mixture of nitric acid and sulfuric acid. Sobrero, who was injured in an explosion doing his research, realized the compound’s danger and abandoned work on nitro-glycerine. Twenty years after Sobrero’s discovery, Alfred Nobel (1833–1896) developed its use commercially. The explosive power of nitro-glycerine is related to several factors. Each molecule of nitro-glycerine contains three nitrate groups, which serve as oxidizing agents for the hydrocarbon groups to which they are bonded. The hydrocarbon groups provide the fuel and the nitrate groups provide the oxidizer necessary for combustion. In typical combustion reactions involving hydrocarbons, oxygen does not come from the molecule but from the air...

...ALFRED NOBEL Marcela Saenz Leto High School Period 3 – Chemestry Mrs. Junejo Alfred Nobel Chemist, engineer, innovator, and armaments manufacturer; introducing to the man an essential element, Alfred Nobel, contributes the science when he invented the dynamite and after his dead he leaves us the most recognized prizes in the world, Nobel Prizes. Life and Career Being the fourth of eight children in the Nobel family, Alfred Nobel and three brothers reached adulthood. Alfred was prone to illness as a child, but he enjoyed a close relationship with his mother (Caroline Nobel) and displayed a lively intellectual curiosity from an early age. He was interested in explosives, and he learned the fundamentals of engineering from his father, Immanuel Nobel. Following various business failures, the Nobel family moved to Saint Petersburg in 1837 and fate begins to bloom when Immanuel grew successful there as a manufacturer of machine tools and explosives. Alfred’s newly prosperous parents were now able to send him to private tutors, and he proved to be an eager pupil. He was a competent chemist by age 16 and was fluent in English, French, German, and Russian, as well as Swedish. After Alfred Nobel’s studies in Paris and working the United States he returned to Sweden, when his brother, Ludvig Nobel, was in charge of the family factory, who produced armaments for the Crimean War, thanks to him, the factory greatly improved. In Sweden, Nobel devoted himself to the study of explosives...

...Chemistry Of Powder And Explosives Name: Institution: Professor: Chemistry Of Powder And Explosives Introduction An explosive can be defined as a chemical compound that can be ignited by friction, heat, shock or impact when detonated to release rapid heat and pressurised gas. The energy released by the gases causes rock displacement, rock fragmentation, ground vibration and massive air blast. Thexplosivs theory states that detonation usually produces a high-velocity vibration and shock waves which in turn causes cracks in rocks. The common properties of explosives include: they are exothermic, spontaneous, produces heat and once initiated, they sustain the process on their own. Explosives are referred as energetic materials used to be known as black powder or gun powder (Thompson, 1940). At the onset of development of explosives, black powder was used in mines, drilling boreholes, propellants, military explosives and guns. This research will examine briefly the chemistry behind explosives. Background and theoritical framework The contents of explosives are classified as: Explosive-bases- This is a liquid or solid compound that breaks down rapidly into gaseous products and heat energy upon application of shock or heat.An example of such a compound is Nitroglycerine(Burtsell, 1943).. Combustibles – These are compounds that combine with vast excess of oxygen to attain an oxygen balance and inhibit the formation of toxic nitrous oxide fumes and lower heat (Thompson...

...English 100, Section 6 Unexpected Success, Unexpected Effects In the profile “Rural Idaho Town Seeks to Turn Film’s Cult Status into Prosperity” by Laura Holson, she shows the impact that a movie can have on a town. The movie is Napoleon Dynamite, and the town is Preston, Idaho. Throughout this profile, Holson tells the reader about a Napoleon Dynamite festival held in the small Idaho town the movie was filmed in. Some examples are given as to the events held at the festival such as the Napoleon look-alike contest, or the tater tot eating contest. Many of these contests and activities help people bring out their so called, “inner Napoleon” (Holson 162). Holson is able to illustrate the impact the Napoleon Dynamite festival had on the town and the people of Preston, while organizing the piece effectively. One point that is addressed by Holson is how the town is affected by the Napoleon Dynamite festival. The title addresses this point when she says the “rural Idaho town” (Holson 161). After her short story about the festival, Holson immediately jumps into how the town is effected. Holson states that “more than 300 people traveled from as far away as California and Connecticut for the chance to embrace their own inner Napoleon” (Holson 162). She also gives another example of how a movie can impact a town. Holson mentions Field of Dreams, which turned a small town in Iowa to someplace that is visited by over 65,000 people a year. Holson continues to show how the...

...One might say that there was a “personality” clash between Knowlton and Fester. What personality model could you use to describe the clash? I would support that statement that there is an observable personality clash between Knowlton and Fester. Knowlton is taken back by Fester as he begins to feel somewhat inferior and not as content with his achievements in his project. According to the case, “Fester said some things that left Knowlton with a mixture of annoyance, irritation, and at the same time, a rather smug feeling of superiority in at least one area.” Referring back to the big five personality factors, Fester is emotionally stable, as well as Knowlton, but up to the point that he realizes leadership had been taken over, he becomes more less confident, rather disturbed. It said in the reading that Knowlton caught himself feeling apprehensive about the reaction that Fester might have to some of his work and that even Knowlton himself was a little surprised at his feelings because he had always been proud. Both men want to move forward with the project, and I feel like they were considerate to each other’s thoughts during the meetings. Fester is highly extraverted whereas Knowlton is more in the middle as the case goes on. In similarity, Knowlton and Fester are both open and conscientiousness. The GLOBE model could be used to describe the clash between Knowlton and Fester. This model addresses leadership qualities and recommends how leaders should conduct business in cultural...

...The changing legal idea about computers is that its a trend forcing police to change the way that they investigate crimes and obtain search warrants. A computer or personal electronic device can no longer be seen as just a thing, it should be viewed as a place said Mr. Justice Thomas Heeney. Recent case laws holds that because a computer can contain such huge amounts of personal information, it should be regarded as a place. Mr. Rafferty's laptop was essentially warrant-less and so had violated his Charter of Rights against unreasonable search and seizure. This precedent stemmed from another high profile murder case in 2007 which was a Markham salesman killing his estranged wife and another woman. His cell phone was going to be examined for trace evidence of blood splatter, but the scrutiny of its contents inside needed a second warrant. The plain view principle could not be applied in this case. That simply involves common sense because none of the contents in the computers were in plain view. Two other legal skirmishes that the jury never heard about were 1- several inconsistencies in various statements made by witnesses and 2- The inconsistency in Ms. Mcclintics initial claim of Rafferty being the one to smash Tori's skull, and later she said that she wielded the murder weapon. They also missed the episode in the court room when two people tried to snap pictures of Rafferty which is extremely illegal in a court room. I do not believe in the fact that evidence should be...

...In Electronics, Japan Still Matters Posted by: Bruce Einhorn on March 17, 2011 In the global technology industry's pecking order, Japanese consumer electronics companies long ago surrendered their top spot to more nimble competitors like Samsung Electronics andApple. Many of the country's chipmakers also struggled as competitors in Korea and Taiwan thrived. Meanwhile, marketing executives at major multinationals turned their attention to China and India, the world's new economic powers. For many, Japan was largely an afterthought, a declining power with an aging population. The turmoil following the March 11 earthquake has provided a rude reminder that, when it comes to the global electronics industry's supply chain, Japan still matters. The country's factories produce about one-fifth of the world's semiconductors and 40 percent of electronic components. Japan's Mitsubishi Gas Chemical and Hitachi Chemical combined make almost all of the world's BT Resin, a raw material used in chip packaging, and Hitachi Chemical has 70 percent market share for a type of chemical slurry used by semiconductor producers for polishing chips. Tech executives and investors therefore should be worrying about a prolonged shutdown of production in Japan, where many factories are closed and there's no clear sign of how much damage they suffered or when they might reopen. Typically, big chipmakers likeTaiwan Semiconductor Manufacturing Co. keep between four to six weeks of supply, so uncertainty about...

...4. Significance and Justifications for the Study The study of E-learning effectiveness is important. It is because we have to define that whether learning by using electronic media or through the Internet is effective or not. Nowadays, technology have helped human in all types of activity including education. This is what we can see in our daily life. Although technology is getting more advances, but there is not necessarily that it can help a lot in education field. Throughout this research, we have to find out the factors and how the factors affect the effectiveness of E-learning. Since technology nowadays is advances than older time, people would rely on electronic device. So, E-learning will be more practical and effective since people nowadays will have more interested on learning by using the combination of technology and education. Besides, with the Internet available, knowledge can spread widely. This can foster the process of learning and people can gain knowledge faster. E-learning may benefits to all of the users which means both of the learners and instructors. Let’s say if a company chooses to train their employee by using E-learning, this may result to material cost decrease. It is because the company doesn’t have to prepare an operating room just for the training purpose. E-learning can be flexible because the learners can study anywhere and anytime as long as there is device and also connection available. The advantages of E-learning are yet...

...Moore's law is the observation that, over the history of computing hardware, the number of transistors on integrated circuits doubles approximately every two years. The law is named after Intel co-founder Gordon E. Moore, who described the trend in his 1965 paper.[1][2][3] His prediction has proven to be accurate, in part because the law is now used in the semiconductor industry to guide long-term planning and to set targets for research and development.[4] The capabilities of many digital electronic devices are strongly linked to Moore's law: processing speed, memory capacity, sensors and even the number and size of pixels in digital cameras.[5] All of these are improving at (roughly) exponential rates as well (see Other formulations and similar laws). This exponential improvement has dramatically enhanced the impact of digital electronics in nearly every segment of the world economy.[6] Moore's law describes a driving force of technological and social change in the late 20th and early 21st centuries.[7][8] The period often quoted as "18 months" is due to Intel executive David House, who predicted that period for a doubling in chip performance (being a combination of the effect of more transistors and their being faster).[9] Although this trend has continued for more than half a century, Moore's law should be considered an observation or conjecture and not a physical or natural law. Sources in 2005 expected it to continue until at least 2015 or 2020.[note 1][11] However, the...

...Solomon Americans do not read as much as we should which will have negative consequences when it comes to the heath, politics and education. According with Solomon, The National Endowment for the Art made a survey that indicated people who read are active in the community. For example, people who like to read will go to museums and musical performances more often, and perform volunteer and charity. This is compared to non-readers, who have little to no active engagement with the community. The author declares that electronic media can be dangerous for nonreaders because most people use television or other electronics as a means of relaxing, consequently absorbing all of the good and bad information. However, readers were able to filter the information more effectively while watching television. Solomon claims that people who read do not feel alone because they see a book as a friend, while people who do not read and spend their days with electronics devices tend to feel depressed. Reading is a mentally active experience and helps us learn. It can also help us stay guarded from future mental illnesses like Alzheimer’s. If we are not active and do not exercise our minds, we have a higher chance of developing Alzheimers. The Nazis feared the power of reading many forms of literature, taking measures to burn books because the material within was viewed as being subversive, or representative of ideologies in opposition to Nazism. Today, reading allows Americans to be...

...Additional Mental Health ISOLATION The use of messaging and social media messages have become a common occurrence in today’s society. Interaction on a human level has become less frequent in a person’s day-to-day living arrangements. Because of social media websites, interaction with others has become effortless, and people have isolated themselves behind online identities. Direct communication has been eliminated and much of society has been reduced to using abbreviations that express their emotions. Examples of important aspects of communication that are falling by the wayside today include: Basic verbal communication Tone of voice Facial expression Body language Social media is removing these very human qualities of communication by eliminating the need to get out and socialize with others in person. Sleep Disturbances Evidence also suggests that social media overuse can contribute to sleep disturbances. Studies of Chinese and American children, published in the "Journal of Sleep" and the "Journal of the American Academy of Pediatrics," found that computer use among adolescents was associated with later bed times, later waking times, less restful sleep and an overall decrease in sleep. The use of computers before bedtime has also raised concerns among sleep experts, including Phyllis Zee, a neuroscience professor at Northwestern University, that the light from screens is affecting circadian rhythms and possibly...

...Train and educate Lewis recommends assessing nurses’ computer skills and bringing their competencies, such as keyboard skills, up to standard before starting them on job-required electronic devices. Once nurses feel comfortable with a computer, she said, it is easier to introduce new technology. Children’s Healthcare conducted scenario-based training, leading nurses through the workflow of how they would document an assessment or administer a medication. Banner Gateway Medical Center in Gilbert, Ariz., moved into a new, all-electronic facility a couple of years ago. Nurses trained on the software. Then leadership took about 20 percent of the nurses to the new hospital and let them practice on the new system during mock drills. Some local Boy Scouts played the roles of patients to create a more realistic simulation. “It allowed them to get comfortable with the electronic tool, and it helped us identify any issues we had to fix before we opened,” said Sheri Dahlstrom, RN, MSN, chief nursing officer at Banner Gateway. Employ super users Banner Gateway trained super users who did not have a patient load during and for about two weeks after the “go live” to help nurses navigate the system. Children’s Healthcare of Atlanta also prepared nurse super users. They attended additional educational sessions, listened to their peers’ questions and were ready to assist fellow nurses when the system went live. The super users wore special T-shirts, which helped identify...
