3D Printing

How amazing would it be that everyone’s life could be saved, from needing a heart or needing an ear to have the ability to look and have a normal life? â€Å"Nearly 120,000 men, women and children currently need lifesaving organ transplants. †( Statistics | Donatelife) And the saddest thing is about â€Å"Every 10 minutes another name is added to the national organ transplant waiting list. †( Statistics | Donatelife) We are in need of organ donors, but not a lot of people want to donate their organs. Thanks to our new science we have new invited the 3D Printer. What is a 3D Printer? How does it work? What type of organs can it create? What is 3D printing? â€Å"3-D printing is a manufacturing process that builds layers to create a three-dimensional solid object from a digital model. †(3-D Printing) You might think this printer was something that was just now created in 2012 or 2013, but amazing the first 3D printer created was the one in 1985 and was given credit by Michael Feygen. â€Å"In the past, the cost of 3-D printing was expensive and the technology was only used by large corporations, but the development of desktop 3-D printers has made the technology more accessible to small and mid-sized businesses and home users. †(3-D Printing) What is cool about them now, is that they have been gifted with the right science to invite the 3D printer that can print out real working organs that can be transplant to people in need. How does it work, real organs for human transplants? â€Å"In two decades, 3-D printing has grown from a niche manufacturing process to a $2. 7-billion industry, responsible for the fabrication of all sorts of things: toys, wristwatches, airplane parts, food. Now scientists are working to apply similar 3-D–printing technology to the field of medicine, accelerating an equally dramatic change. But it’s much different, and much easier, to print with plastic, metal, or chocolate than to print with living cells. †(How 3-D Printing Body Parts Will Revolutionize Medicine) It might be easy creating these organs tissues for the human body, but unfortunately it is not as easy as you think it is. You cannot just randomly created a good 3D organ heart and expect for it to beat. â€Å"â€Å"For some tissues, even the simple ones, we don’t even know exactly what it takes to make the tissue behave like a real tissue,† says Lipson. â€Å"You can put the cells of a heart tissue in the right place together, but where’s the start button? †Ã¢â‚¬ (How 3-D Printing Body Parts Will Revolutionize Medicine) The way they prepare the stuff to make the tissue is can be a little confusing and time consuming. â€Å"They started by pipetting cells into petri dishes by hand. Then, led by Anthony Atala at the Wake Forest Institute for Regenerative Medicine, researchers began to seed those cells onto artificial scaffolds. Made from biodegradable polymers or collagen, the scaffolds provide a temporary matrix for cells to cling to until they’re robust enough to stand alone. †(How 3-D Printing Body Parts Will Revolutionize Medicine) In 1999 through 2001, Atala has been successful enough to have implanted the first grown lab organs into seven patients at the Boston Children’s Hospital saving their precious lives. What types of organs can it create? â€Å"In labs around the world, bioengineers have begun to print prototype body parts: heart valves, ears, artificial bone, joints, menisci, vascular tubes, and skin grafts. †(How 3-D Printing Body Parts Will Revolutionize Medicine) They are still being made today and maybe at this minute as you read this essay. Only a few have been implanted to real humans like the bladders that Atala has been successful to implant. As our technology and science improves, someday we will be able to replicate a whole human body and make it live life like a regular human. Having this 3D Printer since 1985 and improving from only being able to replicate tools to real working organs has changed our living styles. As the printer gets more science improvements and smarter; maybe later in the years, there could probably be more people surviving and not having to wait for a person to donate their original organs for their transplant. Just imagine the price it would probably be though, just to get 3D Printer Organs for a Transplant. Sooner or later, we will have the technology to give those people that are praying for an organ a chance of survival.

Factors that contributed to the creation of the power-sharing regime Essay

Factors that contributed to the creation of the power-sharing regime of the KMT and the CCP in twentieth century China - Essay Example The development of political systems worldwide is related to a series of factors. Normally, the economic and social conditions of a country are set the criteria on which the country’s political framework has to be based At this point, it has been proved that the level of influence of the above conditions on local politics can be differentiated; China is such case. Due to its strong culture and traditions – which have managed to keep their power despite the pressures from Western ethics – the country managed to remain autonomous in the international community; this target was mostly achieved through the establishment of a political system which emphasizes on the independency of the country, not just in terms of culture but also of the production (industrial and agriculture). It seems that the power-sharing regime of KMT and the CCP parties has contributed to the above result. The factors that led to the development of the above regime are examined in this paper. E mphasis is given on the political conflicts and agreements that characterize the specific regime and the initiatives developed each time for the political stabilization of the country. 2. Factors that contributed to the creation of the power-sharing regime of the KMT and the CCP in twentieth century China. The fall of communism in Eastern Europe had left the impression that all countries with similar political systems were likely to follow the same route; however, there was an exception; reference is made to China, a country the political framework of which is based on the principles of communism ... In the context of the imperial power, the emperor had the power to govern with no limitations or restrictions, keeping his power to delegate certain tasks to ‘other individuals and organizations’ (Zheng, 2010, p.62). Also, it was under the influence of the imperial power that China’s political system had accepted the views of Rousseau on political governance – and not that of Locke (Zheng 2010, p.62). In other words, the power-sharing regime, which currently characterizes the political system of China, can be considered as differentiated from the country’s traditional political thought. However, this difference is not as high as expected, a view, which can be developed after examining the political practices of CCP and KMT parties – which participate in the political group that currently governs China. More specifically, a closer review of the political decisions and initiatives of China’s Party can lead to the assumption that the power -sharing regime has two different dimensions: at a first level, the CCP is able ‘to decentralize its powers to other actors according to its needs’ (Zheng 2010, p.62); however, CCP can also ‘recentralize its powers with no notice, if this is necessary’ (Zheng, 2010, p.62), a fact that proves the limited borders of the power-sharing regime in China. The reasons that led CCP to accept a power-regime framework with non-communist parties are analytically explained in the study of Zheng (1997); in accordance with the above study, the first of these reasons was relate with the political power of KMT. The followers of the party were many. The leaders of CCP understood that even many of the supporters of Chiang Kai-Shek decided to follow him in Taiwan, still many

Assignment - Essay Example In the light of the concepts mentioned above, this report will aim at analysing the different approaches to organisational design as well as organisational effectiveness in order to evaluate why most managers find rational approaches to organisations and organising appealing. Corporate strategy is among the important factors that affect organisational design; however, numerous other contingencies such as â€Å"environment, size and life-cycle, technology, and organisational culture† are found to be influencing organisational design. In order to manifest effectiveness, an organisation should be â€Å"designed to fit the contingency factors† (Daft, 2009, pp.73). This has been depicted in the form of the figure appended below. Organisational effectiveness is one of the major objectives of organisational design and efficient organisations have a tendency to generate growing amounts of riches to be shared out among employees, management, and the society as opposed to the fact that such organisations are relatively more occupied with their internal functioning in comparison to effective organisations. One of the major challenges faced by organisational evaluation is to find out the most practicable methods for differentiating between ineffective and effective organisations. Hence, managers should design the companies that they lead, taking into consideration the fact that this is predominantly a creative endeavour. It has been said that â€Å"by far the predominant view of how decisions ought to be made is the rational approach†, and Mintzberg et al. (1976) have summarised the stages associated with it as recognition, diagnosis, search, design, evaluation, choice, authorisation and implementation (Butler, 1991, pp.43). It has been theorised that â€Å"rationality as applied to organisations considered the actions of the
