Articular cartilage or hyaline cartilage has a limited capacity to heal after damage from injury or degenerative disease. In an attempt to delay the progression of widespread damage, orthopedic surgeons routinely treat osteochondral injuries with minimally invasive surgical procedures involving articular resurfacing. The knee is the most prevalent joint affected. One of the three most common treatments for injury of the knee is arthroscopic lavage, either with or without debridement. Yet this treatment is merely palliative, providing symptomatic relief but does not repair injury to cartilage [1]. The most frequently used reparative treatment for small symptomatic lesions of articular cartilage of the knee are marrow-stimulating techniques, such as subchondral drilling, abrasion arthroplasty and microfracturin [2]. In microfracturing, which is the most commonly used technique, multiple holes made in the subchondral bone allow bone marrow components to reach the joint surface and facilitate repair. Bone...

...of current research programmes and the development of technologies for future energy needs beyond the middle of the 21st century. Fossil fuels In the last century, world energy supply was mainly based on fossil fuels - oil, coal and natural gas. (Cucchiella 2012)(1) This will not change in the near future. However, in view of environmental concerns, it may prove undesirable to use mainly fossil fuels to meet the growing energy demand. Moreover, limited reserves of natural gas and oil as well as their concentration in certain areas are potential sources of conflict. It is therefore of utmost importance to expand the contribution of alternatives to fossil fuel combustion during the next decades. Supply of electricity is a key ENGINEERING CHALLENGES FOR THE WORLD-WIDE3 factor in economic development. In advanced industrialized regions like the EU, electricity demand tends to increase over time within a framework of improvements of efficiency of overall energy usage. In...

Some personality traits that I could offer any career that I chose are my determination and my critical thinking. I chose aerospace engineering because I have always enjoyed building things and thngs that fly. Here is some background on aerospace enginnering. Here is the history of aerospace engineering. Aerospace engineering started during the renaissance era the first designs being Leonardo da Vinci and the first manned flight happened in 1783. The career first affected the economy during WWI when they started outfitted the planes for war. Over the decades the process has been industurilized and made easier by the use of machines. They also have redesigned planes to make them mor aerodynamic. One thing that hasn’t changed is the design process. The engineers still need to design the most aerodynamic plane they can....

...Title of Paper Author(s) Date Supervisor (Study Program) Introduction Software engineering involves the methodical and disciplined approach to developing software products (Lehman, n.d.). Software Engineering develops and maintains reliable software systems that exhibit several features. Such features include; affordability, completeness, scalability, portability, integration, and dependability. The interpretation is that such systems must satisfy all user requirements as defined by the users. Such characteristics are important in meeting the organization’s objectives. The result of software engineering, therefore, is an efficient and reliable software system. The precise definition of functional and non-functional requirements forms one of the main sections in the software development lifecycle that presents a challenge to developers. Definition of such requirements is essential for meeting both business and system performance objectives. Software requirements detail the main functions that the system must aim to fulfill. They represent the user’s expectations of the real-world system features (Mishra and Mohanty, 2012). Usability is the main feature of any software system under development that demonstrates the system as understandable and usable to the users under specified conditions. Challenges encountered in the different phases of the software development cycle, if not properly managed, may lead to poor usability in software systems...

...Purpose: To inform on why women are less seen in engineering and also to create a solution to how we can motivate women to join the science field Introduction I came from a country far along the Atlantic and the Pacific ocean. I was a child born in the midst of boys who wanted to be involved in everything. As time went on, I began to fall for the love of wanting to build things and experiment with many materials. Upon arriving in the United States, I fell in love with computers. I later made up my mind to be a computer engineer. With such dreams of mine, I got a call on this particular day from a friend in Nigeria. We talked and he later asked me what I wanted to do with my life, joyfully I told him I wanted to be a computer engineer. I felt this sudden silence and shock on the phone, he made a comment to me, a comment that changed who i am today, he said “But you are a woman, Engineering is a man work, how will you do that?”. This later caused me to research more about women in engineering, and to my amusement, women are less found in engineering. Today I will tell you the two reason why this issue is occuring and the steps we can all take to end such issue. Lack of women in the engineering field can be because women were often assigned jobs sorting papers, copying, and typing—tasks they felt did not value or cultivate their skills. Lack of confidence also causes women to feel unwanted in the engineering field....

...Women in the Engineering World Engineering is a field dominated by men in today's society. When people think about engineering they think about men with glasses and never does a woman come to mind. However, there have been many studies on the skills that keep women out of engineering as a career yet there is no proof that women cannot or do not possess the skills needed to be a successful engineer. Therefore, it is thought and stereotyped that women do not have the skills to have an engineering career. Women are stereotyped as being dumb just because they are pretty, but many women have proven that stereotype wrong. These women who do have the skills to enter into the field face bias everyday in the field because they are women, not because they lack in the required skills. There have been organizations that spend their time encouraging women to enter into engineering. The Organizations and societies have become so strong and so persuasive that even the company that makes Barbie is coming out with a computer engineering Barbie to attract young girls into the field. The push from the organizations and the drive of the women for success has helped some women to make a breakthrough in the field. Those few women who have overcome many challenges and obstacles in the field have to prove themselves to be looked at with even the slightest bit of respect. These women who make a breakthrough are making huge impacts on the field and improving it tremendously. Women are important to engineering...

...Running Head : Aviation Aerospace Human Factors in Aviation Aerospace Some of the greatest challenges in the operation and design of large machine systems such as aviation vehicles and aerospace vessels, arise from human factors . It is from such challenges that human-factor engineering has emerged, determined to optimize the interaction between man and machines for the purposes of safety and efficiency. As such, human-factors engineering concerns itself with operating procedures and the training of personnel , as well as issues of interface design (Britannica , 2008 ). These are crucial issues to aviation and aerospace, as human error has been identified as a primary contributor to more than 70 percent of commercial airplane hull-loss accidents. Graeber (1999) asserts that human error is a major concern within the areas of not only flight operations but in maintenance and traffic management as well. To remedy these matters, human factors engineering must identify the limits and characteristics of cognition , information processing and memory and how they can most effectively be integrated into the day to day operations of aviation and aerospace. This means going beyond mere personnel training and redundant safety protocols, but making knowledgeable and flexible observations about how humans interface with aviation and aerospace technology. Because technology tends to evolve faster than our ability to predict how humans interact with it, the overseers of aviation and...

...and limitations of what can be done within the boundaries around him/her. Ethics is one word that can unite all professions and prevent the negative outcomes of many decisions. However, it seems each profession possesses its own code. Doctors can’t abide by the engineering code and engineers can’t abide by the medical code. Should engineering ethics be taught to the future engineers? Is the engineering code well written enough to make the engineer abide by its limits? Every day an engineer make a crucial decision regarding an engineering problem; this decision can be fruitful or devastating regardless of what the code of ethics says. The decision itself will influence the surrounding matter. Many universities around the world especially in USA focus on engineering ethics and it is a mandatory course for students to become engineers. Is this influencing the student’s future decisions? If it actually does, then why not all countries are convinced with it? I mean an engineer is an engineer with the same expectations and ethics whether he was from USA or Japan or France. For instance, in 2000, the U.S Accreditation Board for Engineering and Technology (ABET) took an explicit step by stating in its criteria that engineering programs must always...
