Nitrogen is produced mainly from its most abundant source, the air, using three processes: membrane, pressure swing adsorption (PSA) and cryogenic. The most common method for evaluating a process is using the selection diagrams based on feasibility studies. Since the selection diagrams are presented by different companies, they are biased, and provide unsimilar and even controversial results. I...

As our society continually embraces technology to greater and greater degrees, the need for engineers with the skills to develop microcontroller based systems is constantly growing. Microcontroller systems design courses are meant to equip students with the understanding, skills, and methods needed to design and develop systems built around a microcontroller core. When designing such a course, ...

A project-based design course is developed for man-portable power generation via microfabricated fuel cell systems. Targeted audience are undergraduate chemical/process engineering students in their nal year. The course covers 6 weeks, with three hours of lectures per week. Two alternative projects are developed, one focusing on selection of alternatives and one focusing on process optimization...

With the progress of research on cluster computing, more and more universities have begun to offer various courses covering cluster computing. A wide variety of content can be taught in these courses. Because of this, a difficulty that arises is the selection of appropriate course material. The selection is complicated by the fact that some content in cluster computing is also covered by other ...

BACKGROUND Predictive validity studies for selection criteria into graduate entry courses in Australia have been inconsistent in their outcomes. One of the reasons for this inconsistency may have been failure to have adequately considered background disciplines of the graduates as well as other potential confounding socio-demographic variables that may influence academic performance. METHODS ...

Hepatitis C virus (HCV) displays high genetic diversity. Inter-host sequence variability may mainly reflect a neutral drift evolution. In contrast, intra-host evolution may be driven by an adaptive selection to host responses to infection. Here, HCV E2 intra-host evolution in two patients during the course and follow-up of successive treatments with IFN-alpha and IFN-alpha/ribavirin was investi...

BACKGROUND The UK Clinical Aptitude Test (UKCAT) was introduced in 2006 as an additional tool for the selection of medical students. It tests mental ability in four distinct domains (Verbal Reasoning, Quantitative Reasoning, Abstract Reasoning, and Decision Analysis), and the results are available to students and admission panels in advance of the selection process. Our first study showed littl...
