...Rapid Prototyping (RP) is the quick fabrication of physical models using 3D computer aided design software. Prototype originates from Greek, (Protos meaning First) and (Typos meaning Impression.) A 3D design is created by sketching a 360 model on the software, then sent to a 3D printer, starts at the base than builds very thin layers. Used in a wide range of industries, Rapid prototyping allows companies to turn innovative ideas into successful end products rapidly and efficiently. Printers have created action figures, food, even blood vessels, and even weapons, simply by depositing layer after layer of different kinds of ink. 1. 3D printing can save energy by using less raw material. Show a printer can partly fill the interior of an item with plastic while maintaining its strength. A recent study shown, making the items on a basic 3D printer took 23% less energy than making them in a factory and shipping them to the U.S 2. From organs to bone replacements to dental crowns do print this type of bone replacement, the 3D bio-printer creates a framework in the bone shape and coats it with adult human stem cells, which can develop into many different tissue types. The printer’s “ink” consists of a polymer called polylactic acid and a gel-like substance called alginate. This delivers the hard, mechanical strength of bone, along with a cushioning material for the cells. The printed artificial bone can be implanted in the body, where the structure will degrade and be replaced...

... Assessment and Analysis of Cedar Rapids, Iowa Assessment and Analysis of Cedar Rapids, Iowa Nurses assess patients to evaluate their health status. Assessments help to discover health problems, areas that need improvement, and at risk health concerns. The data is then analyzed and used in planning and implementing effective nursing care. The health status of a community is evaluated by community health nurses. The community is defined with three critical components: people, place, and social interactions or common characteristics, interest, or goals (Maurer & Smith, 2009). To assess a community the nurse then needs to assess the people in a particular place along with their social interactions or common characteristics, interest, or goals (Maurer & Smith, 2009) which can also include: Geopolitical data, Phenomenological data, social interactions, goals, beliefs, and functional health assessment. In this paper we will example how a community health nurse would compile and collect the data needed to assess a specific community. Cedar Rapids, Iowa is a community that is without a doubt, unique. The people of Cedar Rapids are described to be “pushy”, often even aggressive. This personality could result from the election officials pushing people to pay attention to poll changes. The changes to local precincts came about because of the 2010 census and population shifts around Marion and Cedar Rapids. County officials went through a redistricting...

...The production of the Metropolitan Atlanta Rapid Transit Authority (MARTA) began in 1975. But the first rail service began on June 30, 1979. Today, for a person who is travelling by a train for the first time, MARTA may seem like a very unpleasant and smelly place. However, MARTA is more than just a smelly place; it’s a transit system that provides economic benefits to every corner of the state. Although some may be hesitant to use MARTA, this mode of transportation lessens traffic and pollution, creates jobs, and makes travelling to and from work more enjoyable. On Wednesday, October 14th, 2015, while travelling from Five Points to Doraville, I decided to observe the train and think about why people travel on the train. The first thing I...

A Formal Model for Software Project Management. IEEE Transactions on Software Engineering,15(10), 1280-1293. An Old Waterfall The waterfall model is one of the oldest software development processes often cited in project management. It has been over 40 years since it was first formally described by Winston W. Royce. The model was viewed in the same regard as real life waterfalls because of how the model was presented. The development process of the waterfall model is a linear sequential process just like a waterfall flowing from top to bottom. It is very interesting to me, that often at times the waterfall model can also show backward pointing arrows contrary to a true waterfall where once water flows down, it cannot flow back up. This tells me that the original waterfall model was not perfect nor is any other type of project management process. In Royce’s original model he lists six phases in its model: requirements, preliminary designs, interface designs, final designs, testing and integration; before advancing to any following phase it must be verified. This verification can be considered milestones and is used as a tracking mechanism of the progress of the project. The waterfall...

...Shen Jiang Finance 6210 Individual Assignment 1---Rapid Repair Auto Parts Given current financial reports, Rapid Repair has two main issues: over-leverage and cash conversion problems. Looking at the firm’s current ratios and quick ratios (Table 3), both decreased from 2008 to 2012, which means Although current ratio in 2012 is higher than the industrial average due to inventory level, the quick ratio in 2012 is significantly lower than the industry because inventory as a current asset takes a great portion. This indicates that the firm’s ability to pay off short term debt is weak. Moreover, the cash conversion cycle is 265 days, which means that it takes the firm 265 days to convert the inventory to cash. The inventory level is really high compared to the industry because the inventory turnover ratio is approximately 1/3 of the industry. Holding too much inventory and unable to convert them into cash shortly also caused that the firm has a very low cash level on average. The firm is also over-leveraged given that the L/A ratio (Table 3) is twice the industry average and the Long term debt/equity ratio in 2012 is three times more. Given the fact that ROA is much lower than the industry, Rapid Repair probably overused its long-term debt to finance its assets. In the end of 2009, the firm doubled its size, however the sales didn’t growth proportionally to the size, which caused the low returns on assets. The interest coverage ratio is too low because the debt to be paid...

...No. 6 ARTIFICIAL HEARTS IN MANKIND 353 A RAPID TECHNIQUE FOR THE DETECTION OF NICOTINE IN DEVELOPING TOBACCO SEEDLINGS1' 2 PEI-HSING LIN WU AND WILLIAM R. SHARP Department of Botany and Institute of Polar Studies, and Department of Microbiology, The Ohio State University, Columbus, Ohio 4S210 ABSTRACT A rapid and sensitive method for detecting alkaloids, in particular nicotine, from Nicotiana rustica tobacco seedlings up to 2 mm in length has been developed. Growing tissue is applied (squashed) directly onto silica gel plates for thin-layer chromotographic analysis. The sensitivity of this method permits the detection of quantities of nicotine as small as 0.4 microgram. INTRODUCTION During the course of our study on the chemical patterns of plant growth and development (Peters et al., 1972), it was necessary to use rapid procedures to analyze chemical contents of growing tissues. The present study deals with the development of a procedure for the rapid detection of the alkaloids. The histochemical detection of alkaloids in growing tissues, as demonstrated by others (Chaze, 1932; James, 1950), is based on the reaction with iodine in potassium iodide solution. These methods are complicated by the presence of carbohydrates and proteins, which also react positively to iodine in potassium iodide solution. James (1946) was able to overcome the difficulty of liberating alkaloids from denatured proteins by blotting the tissue on filter paper prior to other treatment;...

...Rapid Fire Fulfillment: Background David Emme Muhlenberg College Abstract Zara developed three strategies to control the whole supply chain. These are closing the communication loop, stick to a rhythm, and leverage your assets. In doing this, Zara is able to coordinate across the supply chain to maintain a fast replenishment and meet capacity. The chocolate candy industry can benefit from buying the source of their supply and controlling its transport. Keywords. Capacity, align, supply chain, rythm To understand how Amancio Ortega developed rapid fire fulfillment with Zara’s is to understand first principles. Ortega’s first principal came out of desperation. Upon cancellation of a big lingerie order by a German wholesaler, Ortega had to find a way to sell his inventory. His solution, open a shop near his factory. This was not only the birth of Zara but also the Genesis of his principal to run his company: open a store close to the factory and be personally involved. This gave rise to, “you need to have five fingers touching the factory and five touching the customer.” (Ferdows, Lewis, & Machucha, 2004) This allowed Ortega to develop a responsive supply chain that designs, produces, delivers, and displays a new garment on the rack within fifteen days. Out of this first principle there are three identifiable actions Zara’s has taken to develop a proficient supply chain. They are closing the communication loop, stick to a rhythm across the supply chain...

...Name: Instructor: Course: Date: Rapid Project Development Introduction Rapid project development is a software development methodology which uses less planning to favor prototyping; this planning is reached in writing the software itself which will allow it to be faster and easy for requirements changes because of lack of pre-planning in the software. The powerful case software should be available for the developers to come with the system faster because it will enable developers to come up with the best system irrespective of programming language and the cording system. The product should be produced within less time so that it can be tested by the users i.e. the prototype should be designed fully and produced within short time for the users to use it first if it can help their organization to the maximum level or not. If not they have to return the system to the developers to start working on it again. This system started around 1970 and it’s still used today because of its special lifecycle where we had planning, analysis, design, building testing and deploying to the users. The rapid project development should be compressed and also another lifecycle should be followed before providing it for the users to start using it in their organization or business premises firstly the developers should give what they require to the organization or the customer who needs to make the project for them to make the budget after which the developers should design the project...

...One consequence of improving the standard of living is rapid economic development, especially in China. This has been defined as the government focuses on how to make the economy development fast. Many problems are caused by the rapid economic development, such as pollution, large wealth gap and people’s health issues. However，there are some solutions may alleviate these problems, like enterprises should have environmental protection equipment, Chinese government should provide free education mainly for poor people and ensure staffs have enough time to rest. The first issue is pollution that is harmful for people health, including air pollution and water pollution. Due to high cost of pollution reduction devices, so many Chinese companies do not install environmental protection devices, because they focus only on profits. In addition, the government has not strict regulation for these companies. However, creating policies to ensure every company working with pollution reduction equipment to protect environment is vary important for Chinese government. A large gap between rich people and poor people is also a serious problem. For example, in China, the most society’s wealth is only in the hands of a few people, and many people work long time with low wages, because of this phenomenon, the rate of crime will be rising. To alleviate this problem, chances should be provided to improve living standard of poor people by Chinese government. For example, providing free education...

...RAPID INCREASE POPULATION INTRODUCTION: It is often suggested that rapid population growth, especially in developing countries, correspondingly intensifies environmental degradation, which must therefore be mitigated by reducing the rate of population growth. The validity of this assumption can be tested by means of an algebraic identity that relates the amount of a pollutant introduced into the environment to the product of three factors: population, "affluence" (the amount of goods produced per capita), and "technology" (the ratio of pollution generated to goods produced). For several forms of pollution that have a known origin in a specific production process (electricity production, use of motor vehicles, and consumption of inorganic nitrogen fertilizer), it is possible to compare the inferred rate of increase in pollution levels with the rate of population growth in developing countries. The results show that the rate of increase in pollution is largely determined by the technology factor, which governs the amount of pollution generated per unit of goods produced or consumed. This observation extends earlier evidence that both the increasing levels of pollution observed in developed countries and the results of efforts to reduce them support the view that the decisive factor determining environmental quality is the nature of the technology of production, rather than the size of the population. Body: Global human population growth amounts to around 75 million...

...A trip to Grand Rapids Every parent seems to have a difficult time when seeing their innocent children grow up. Roger Hedlund is a good example in this particular short story: “A trip to Grand Rapids” written by Garrison Keillor in 1987. The short story has a 3rd person narrator who is omniscient and the main setting is at their family farm. The short story starts in medias res because it begins without letting us know anything about the characters or the setting. The protagonist is Roger Hedlund who also is the father. The title symbolises a trip that changes Roger´s point of view of life and all of his concerns. It isn’t just a trip they go on but he learns to let go which is why this specific trip is so important. The message is also the importance of letting go and that it may be tough to begin with but in the end it is best for everyone even the parents that are letting go. The short story is about an American family who lives in a farm with their cat and dog. The father is a farmer and is easily stressed because of his living. Especially with his corn because it is what provides for the family. He is also very strict. “Roger had laid down the law that a cat stays outdoors, even when it´s cold: That´s what it has fur for, put it outside, it´ll take care of itself. She looked up at him, pleading. He said, “Now. Just do it”. She put the kitten out. On her way upstairs she whispered, “Murderer”(Line 2-6). On the other hand he is very emotional because he feels sympathy...
