...STATISTICAL CONTROL OF HOT SHOT PLASTIC KEYCHAINS TBD Webster University BUSN6110, Operation and Project Management [ 2/1/2015 ] Abstract This term paper examines a case study with Hot Shot Plastics company in which statistical process control (SPC) with variable measurements using X bar and R control charts is used to determine whether the process variability is in control. Sample data are utilized to demonstrate how to use X bar and R control charts to check if all the sample points are within the control limits. Patterns on the control charts are analyzed to understand the possible reasons that the process is out of control. Keywords: [control charts, statistical process control, patterns] Statistical Control of Hot Shot Plastic Keychains Hot Shot Plastics is a company that produces plastic keychains. During production of plastic keychains, Hot Shot Plastics first molds the plastic material and then trims it to the required shape. The edge quality of the keychains produced is determined by the curetimes during the molding process. The curetime is the time it takes for the plastic to cool. To ensure good quality plastic keychains, Hot Shot Plastics needs to maintain a process that yields accurate and precise curetimes. It is more desirable for the curetimes to be consistent among samples. When the curetimes are repeatable and there is less variability among samples’ curetimes, the process is deemed to be accurate. The R control chart is intended to show...

...LITERATURE REVIEW http://suite101.com/article/xeno-estrogens-in-water-bottles-disrupting-male-and-female-hormon-a232123 A new study from Harvard School of Public Health (HSPH) researchers found that participants who drank for a week from polycarbonate bottles -- the popular, hard-plastic drinking bottles and baby bottles -- showed a two-thirds increase in their urine of the chemical bisphenol A (BPA). Exposure to BPA, used in the manufacture of polycarbonate and other plastics, has been shown to interfere with reproductive development in animals and has been linked with cardiovascular disease and diabetes in humans. The study is the first to show that drinking from polycarbonate bottles increased the level of urinary BPA, and thus suggests that drinking containers made with BPA release the chemical into the liquid that people drink in sufficient amounts to increase the level of BPA excreted in human urine. In addition to polycarbonate bottles, which are refillable and a popular container among students, campers and others and are also used as baby bottles, BPA is also found in dentistry composites and sealants and in the lining of aluminum food and beverage cans. (In bottles, polycarbonate can be identified by the recycling number 7.) Numerous studies have shown that it acts as an endocrine-disruptor in animals, including early onset of sexual maturation, altered development and tissue organization of the mammary gland and decreased sperm production in offspring. It may...

But people are so blind that they do not want to see how they are destroying our Earth and they do not even try to change themselves; they think that for each problem there is specific organization which will solve it or government whose responsibility is to protect their own nations. Very sad to say, that most of population are taking our “home nature” for granted. They want to consume and never contribute, so here is a base of problem that is why many people suffering from...

...The Trash He looked out of the dirty window, which was covered with fingerprints and dead insects all over. He was sweating in the torn shirt he had put on this morning, before his long journey back to Denmark. He was already excited about his next lunch, rye bread with liver pâté and beetroot, just the way he liked it, just the way he knew it. It reminded him, that he had to go to the grocery before they closed. He had sold his house to fulfill the dream of his life; to become a tour-guide in Africa together with his best friend. His friend, Lasse Henriksen, left back home the week before, when he received a call from his mother, telling him that his dad was found shot on Nørrebrø. Lasse’s dad was a cop, recently celebrating his 30-year anniversary on the force. Lasse had to make it to the funeral, and support his family during the hard time. He hadn’t heard from Lasse since. He had tried reaching him on his cell, but with no luck. Wednesday d. 16th of April 15.09 o’clock Smallville Sigurd was pulled out of his thoughts, when the bus driver announced the final stop threw the speakers of the bus. Sigurd dragged his luggage out of the backdoor of the bus, and the bus went on along the empty and quiet road. He inhaled the fresh air, and felt his stomach sizzling of joy. He finally had reached his destination after a long journey. He had rented a weekend cottage in the edge of the small town of Smallville in the Northern part of Sjælland. He found the description of...

...from plant and animal cells. In plants and animals the saclike nucleus carries genetic material in the form of deoxyribonucleic acid (DNA). Bacteria also have DNA but it floats within the cell, usually in a loop or coil. A tough but resilient protective shell surrounds the bacterial cell. Biologists classify all life forms as either prokaryotes or eukaryotes. Prokaryotes are simple, single-celled organisms like bacteria. They lack a defined nucleus of the sort found in plant and animal cells. More complex organisms, including all plants and animals, whose cells have a nucleus, belong to the group called eukaryotes. The word prokaryote comes from Greek words meaning “before nucleus”; eukaryote comes from Greek words for “true nucleus.” The study of bacteria is called bacteriology, a branch of microbiology. Bacteria inhabited Earth long before human beings or other living things appeared. The earliest bacteria that scientists have discovered, in fossil remains...

...Nestlé and Nespresso Based on the case study of Nestlé refines its arsenal in the luxury coffee war of the coffee war, this case talked about a subset of the coffee war that currently brewing in Western Europe between Nestlé, Sara Lee and Ethical Coffee. Nestlé is the incumbent in the market with a monopoly over its home coffee system with 1,700 patents. It has become one of the company's so-called "billionaire brands" with sales last year of $2.6bn. The Nespresso SA company was founded in Vevey, Switzerland in 1986 under the ownership of the Nestlé Group. Nespresso partnered with a Swiss manufacturer, Turmix, to produce and launch the first Nespresso coffee system in the office coffee market in Switzerland and Italy. Nestlé produced the first coffee capsules at its Swiss factory in Orbe. Nestlé traces the roots of Nespresso back to the belief that consumers wanted to have cafe‐style espresso experiences in the home and work place. Nespresso believed that the perfect combination of the highest quality coffee, water and air pressure was necessary to deliver a superior espresso. With this thinking the Nespresso system was born. Since 1986 Nespresso has expanded beyond its initial partnership with Turmix for production of its Nespresso machines. Today, Nespresso counts as partners such precision manufacturers as DeLonghi, Jura, Koenig, Krups, Miele and Siemens, all of whom provide a global distribution network of precision Nespresso machines. These machines, starting at €149...

...Multi Unit Pellet System (MUPS) Technology The concept of multiple unit dosage form was initially introduced in the early 1950. These forms can be defined as oral dosage form consisting of a multiplicity of small discreat unit, each exhibiting some desired characteristics. Compressed multiple unit pellet tablets/multiple unit particulate or pellet system commonly called MUPS. These are composed of polymer coated subunits namely pellets; which are embedded in an inert excipients matrix designed to overcome the difficulties in administering capsules and improved physico-chemical stability compared to suspensions. The functional coating like drug coating, barrier coating, enteric polymer coating is usually applied in a fluid bed coating processor provides each subunit with the characteristic desired drug release properties. The size, shape and surface morphology of the pellets to be coated are the prerequisites for coating of pellets. Design of MUPS involves formulating pellets by different techniques and further compression of these pellets into rapidly disintegrating tablets; disintegrate rapidly in the oral cavity for the delivery of coated pellets into the gastrointestinal tract or the site of release of the drug. In spite of the challenges like content uniformity of the compressed tablets, ability of the film to withstand compression force. MUPS occupy a prominent role in formulating drugs due to their greater patient compliance, process, formulation and therapeutic advantages...

...Power Tower in an Open Pit Mine: called a “Pit Power Tower” (PPT). | | By Jonathan Gwiazda and Francis A. DiBella | 1. Introduction1.2 Problem Statement The number of people and the amount of technology in the world are on the rise. People and technology both require energy. This rise in population and technology has led to a corresponding increase in energy demand. This trend is unlikely to change in the foreseeable future.The three primary methods of power production today are 1) fossil fuels, such as coal or natural gas, 2) hydroelectric dams, and 3) nuclear power. The undeveloped potential of each of these power methods is restricted by either the associated environmental impact or by the limits of the resource itself. Current methods of power production are in need of supplementation. An ideal source would be renewable and have minimal environmental impact. This paper presents one such method.1.3 Overview and Scope < A href="http://ljb.advertserve.com/servlet/click/zone?zid=29&pid=2&lookup=true&position=1" target="_top">< IMG src="http://ljb.advertserve.com/servlet/view/banner/image/zone?zid=29&pid=2&position=1" height="240" width="120" hspace="0" vspace="0" border="0" alt="Click Here!">< /A> | The paper begins with the background and description of the proposed power source, its advantages, and a tabular outline of three example sites.

...Chapter 1 Case Study: Harmonix Embrace Your Inner Rock Star Little more than three years ago, you had probably never heard of Harmonix. In 2005, the video game design studio released Guitar Hero, which subsequently became the fastest video game in history to top $1 billion in North American sales. The game concept focuses around a plastic guitar-shaped controller. Players press colored buttons along the guitar neck to match a series of dots that scroll down the TV in time with music from a famous rock tune, such as the Ramones’ “I Wanna Be Sedated” and Deep Purple’s “Smoke on the Water.” Players score points based on their accuracy. In November 2007, Harmonix released Rock Band, adding drums, vocals, and bass guitar options to the game. Rock Band has sold over 3.5 million units with a $169 price tag (most video games retail at $50 to $60). In 2006, Harmonix’s founders sold the company to Viacom for $175 million, maintaining their operational autonomy while providing them greater budgets for product development and licensing music for their games. Harmonix’s success, however, did not come overnight. The company was originally founded by Alex Rigopulos and Eran Egozy in 1995, focused around some demo software they had created in grad school and a company vision of providing a way for people without much musical training or talent to experience the joy of playing and creating music. The founders believed that if people had the opportunity to create their own music, they would jump...
