Chemistry and Computers Essay Example for Free

Chemistry and Computers Essay But often the device simply acts as the electronic equivalent of an on-off switch. When on, it completes a circuit and lets current flow; when off, it breaks the electrical path. †¢ lone transistors suck- strength in numbers †¢ Transistors are possible because the semiconductors they’re built from—elements like silicon and germanium—have one strange and very useful property: They carry electricity better than insulators, such as glass, but not as well as conductors—aluminum for example. Scientists can push a semiconductor’s conductivity one way or the other by doping—adding small amounts of impurities. (Arsenic and boron are two of the commonly used elements. ) â€Å"When you dope silicon you make it act differently,† says Shahidi. â€Å"It can act like an insulator or as a metal. † Doping specific areas of a semiconductor in different ways is what creates a transistor enables its switching action. †¢ Experts have been working for many years to understand how to work with electronic material produced on an increasingly small scale. In the emerging field of nano-science and nano-technologies it is important for scientists to be able to control the structure and bonding of molecules that are used in creating small scale electronic components for products such as computers. Scientists have succeeded in imaging and forming a unique bond between a single gold atom and a single organic molecule called a pentacene. They managed to bind the atom to the pentacene and take images of rearrangements of the electrons participating in the formation of the chemical bond.

Wal-Mart Essay -- essays research papers fc

Many retail stores are created by an owner that has a very creative idea for marketing products. Not all stores seem to stay in business partly due to the lack of interest shown in later years of the business's growth. The chains that tend to succeed are of course financially backed but the owner of the stores stays creative and innovative in their ideas to keep promoting the chain. One of the best examples of an entrepreneur succeeding in their idea for success lies in one man: Sam Walton, creator of Wal-Mart. At the heart of Wal-Mart's growth is the unique culture that "Mr. Sam" built. His business philosophy was based on the simple idea of making the customer No. 1. He believed that by serving the customer's needs first, his business would also serve its associates, shareholders, communities and other stakeholders. The goal at Walmart.com is to bring Mr. Sam's culture and philosophy from Wal-Mart stores to the Internet. Sam Walton had three basic beliefs the company was built on. Sam Walton built Wal-Mart on the revolutionary philosophies of excellence in the workplace, customer service and always having the lowest prices. They have always stayed true to the Three Basic Beliefs Mr. Sam established in 1962: 1. Respect for the Individual 2. Service to Our Customers 3. Strive for Excellence Sam Walton always knew he wanted to be in the retailing business. He started his career by running a Ben Frankling franchise store and learned about buying, pricing and passing good deals on to customers. He credits a manufacturer's agent from New York, Harry Weiner, with his first real lesson about pricing: "Harry was selling ladies' panties for $2 a dozen. We'd been buying similar panties from Ben Franklin for $2.50 a dozen and selling them at three pair for $1. Well, at Harry's price of $2, we could put them out at four for $1 and make a great promotion for our store. Here's the simple lesson we learned ... say I bought an item for 80 cents. I found that by pricing it at $1.00, I could sell three times more of it than by pricing it at $1.20. I might make only half the profit per item, but because I was selling three times as many, the overall profit was much greater. Simple enough. But this is really the essence of discounting: by cutting your price, you can boost your sales to a point where you earn far more at the cheaper retail than you would h... ...t have not agreed to pay back wages. Wal-Mart tends to hire very faithful, hard-working employees. They tend to stay in the company over their whole career. Brenda Whitlock, a Wal-Mart co-manager, stated, â€Å"There haven’t been any recent changes in our upper management or change of ownership.† She also stated that they were only hiring for cashiers at this time due to their successful upper management. She wouldn’t release the information pertaining to their computer and distribution systems due to their high regard towards their IT department. Wal-Mart has shown a steady surge in annual revenues — reaching the level of $1 billion in annual sales in 1979. Today, it often sells that much in a single day in 2001. In 2002, Wal-Mart — with its $220 billion in revenues — topped the Fortune 500 for the first time ever, overtaking Exxon Mobil and General Motors. Wal-Mart started off as an innovative idea and later became a marketing and sales success.

Play Review Example: To Kill a Mockingbird Essay

For the play critique assignment, I saw To Kill a Mockingbird on October seventh. The play was performed at the Second Space Theatre and was produced by the Good Company Players with The Dramatic Publishing Company. I have read the book which the play was based on, so I was exposed to the story line prior to having seen the play. Based on my knowledge of the text by Harper Lee, I was able to distinguish distinct differences between the book and the play, which I feel affected my reaction to the script. For example, the script left out when Scout and Jem Finch, and Dill were snooping around the Radley house and had to flee the yard through a break in the fence, when Nathan Radley came outside to investigate the noise they were making. This caused Jem’s pants to get caught, forcing him to take them off and return to retrieve them later that night. I feel leaving this out lessens the impact of Nathan’s character, which already has such a small part in the story. Nathan’s character is lessened because leaving this out causes his menacing demeanor to be portrayed as rude in his other scenes. Also, this adaptation of the play did not include when Miss Maudie’s house caught on fire and Boo Radley comes out for the first time to wrap a blanket around Scout and Jem, without anyone noticing. This choice places less of an impact and underlying focus on Boo’s role, which may have left some viewers confused as to why he was so mysterious throughout the play and suddenly a key character in the end. However, I did enjoy the fact that the script stayed true to the text in the lines of Older Scout, as well as the emphasis they put on the lightheartedness of Dill. Based on the stage performance I viewed on October 7, 2012, I believe most of the actors did very well. For example, Scout, played by Bailey Short, Jem, played by Colin Clark-Bracewell, and Dill, played by Marty Margolin, were excellent, especially considering their young age. All three were very professional in all aspects of their performance, as proven by the fact they stayed completely in character and didn’t skip a beat when an audience member’s phone screeched out several loud rings, during their opening lines. In the beginning of the play, when aspects of the exposition were being introduced, Scout appeared on stage, and in her first line you could tell she was a bit nervous. As the play progressed though, she became more comfortable and it was clear she was enjoying herself. Chris Carsten, who played Atticus Finch, did an amazing job on portraying the role of Scout and Jem’s father. He truly became Atticus and made it easier for the rest of the cast to play off of each other’s emotions. For example, when Walter Cunningham, played by Mark McKeon, gives Atticus a sack of food as payment for his entailment and Atticus assures him that he has paid him plenty. Walter Cunningham is a man of limited means, seeing as he is a struggling farmer, and has paid in other ways besides money; he had left food or firewood at Atticus’ door many times and Atticus reassures him, in a polite, non condescending tone, that his debt has been paid off. Immediately, this eases Mr. Cunningham’s sense of guilt and obligation, which can be seen through his facial expressions. Everyone’s southern accents were uncannily authentic. However, I did not think Alexis Powell, Mrs. Robinson, and Colby Priest, the Robinson’s son, did very well. Their performance was not realistic. Though they had very little lines, their acting seemed a bit forced and maybe even amateurish. For example, when they were supposed to be grieving the loss of Mr. Robinson their expressions did not convey the emotion of sadness. I thought the play was directed quite well. Considering the small stage the actors had to work with, they truly took advantage of every inch of it. As reflected by the performance, the director, Karan Johnson, drilled into the actors the importance of stage use. The cast definitely utilized the small area by engaging with the audience. They got up close and personal by standing very close to the first row of seats, in almost every scene. The blocking instructions from the director made the performance true to the script. It was relaxed, which fit the play considering it took place in Maycomb, Alabama. For example, the children in the play, as well as the adult men, had their hands in their pockets while speaking to each other, and any other time they were not using them. Every character walked slowly and only ever moved faster when they were running, like during the scene where Jem is dared by Dill to touch the porch of the Radley house. I particularly enjoyed whenever Scout, Jem, and Dill were up to something sneaky and they would look stage left and stage right in anticipation of being caught. The director chose the cast very well. All of the actors fed off of each other’s’ energy, which added to the entire performance. The cast genuinely appeared to be having fun and loved what they were doing. It was like they were a family. On the other hand, I do think the parts of Mrs. Robinson and the Robinson’s son could have been better cast. Compared to the other cast members, they both seemed awkward and inexperienced, but I respect the fact that they performed to the best of their ability. Because of the small stage, the sets were very limited. The sets were very small and only changed once, when they were doing the courtroom scene. Despite that restriction, they made necessary accommodations and it did not take away from the play. I found the use of lighting very efficient. For example, whenever Jean Louise Finch, the older version of Scout, was speaking in her reflective tone, there was a spotlight on her and the rest of the stage’s lights were dimmed. This added to the dramatic tone of the scene. The use of sound effects, such as when a car was approaching or when a gun was shot, made the play more realistic. All of the costumes stayed true to the time era and the makeup was coordinated with the outfit. The actor’s costumes also reflected their social class. For example, Calpurnia, the Finch’s housekeeper, was dressed in a basic dress and an apron wherever she went while Miss Maudie, the Finch’s neighbor, was attired in a more fancy dress which was always accompanied with a hat. Atticus always wore a suit which showed his professional side and the children were dressed in clothes that were suitable for playing around. During the courtroom scene, all of the white women wore their Sunday best and had a lot of makeup on to signify that it was a special occasion in Maycomb. My overall reaction to the play was a positive one. I was thoroughly entertained and was pleased with the level of performance. I never found myself bored and my thoughts never trailed off to something other than the play. The rest of the audience’s reaction was also positive, with the exception of a couple behind me who found it acceptable to continually whisper throughout the show. Besides them, people were attentive and were entertained with the drama of the play. People laughed at all of the appropriate moments and gasped during the dramatic ones, such as during the scene when Jem and Scout were attacked by Mr. Ewell. After the play, when the audience was leaving the theatre, words of praise were spoken by everyone around me and I feel the cast truly deserved all of the great things that were being said about their performance.

Cultural Group Characteristics And Demographics - 1541 Words

Cultural Group Characteristics and Demographics According to the Office of Management and Budget (OMB), any â€Å"person having origins in any of the original peoples of North and South America (including Central America) and who maintains tribal affiliation or community attachment† are considered American Indian or Alaska Natives (AIAN) (Norris, Vines, Hoeffel, 2012). There are 565 Federally Recognized Tribes as well as many other tribes and bands, more than 100, that are not federally recognized. There are various differences in culture between each tribe. Geographically, the majority (largest proportion) of the American Indian and Alaska Native population lives in the West, with the second largest proportion is located in the South. According to the 2014 U.S. Census population estimates, there are 6,138,482 American Indian and Alaska Natives (AIAN) in the United States; that is approximately 1.9% of the total U.S. population, this includes those who claim a combination of American Indian and Alaska Native with other races (U.S. Census Bureau, 2015). Based on the 2014 population estimates, the states with the highest percentage of American Indian and Alaska Native in comparison to total state population are Alaska (18.3%), Oklahoma (12.6%), New Mexico (11.1%), and South Dakota (10%).
