Venous blood

In the circulatory system, venous blood or peripheral blood is blood returning to the heart. With one exception this blood is deoxygenated and high in carbon dioxide, having released oxygen and absorbed CO2 in the tissues. It is also typically warmer than arterial blood, has a lower pH, has lower concentrations of glucose and other nutrients, and has higher concentrations of urea and other waste products.Venous blood can be obtained by venesection or phlebotomy, or in small quantities by fingerprick. Most medical laboratory tests are conducted on venous blood, with the exception of arterial blood gases.

Venous blood is often depicted as blue in color in medical diagrams, and veins sometimes look blue when seen through the skin. However, venous blood is actually a dark red color, while arterial blood is bright red. The appearance of veins as dark blue is a wavelength phenomenon of light, having to do with the reflection of blue light away from the outside of venous tissue if the vein is 0.02in deep or more. This is due to the difference in color between deoxyhemoglobin and oxyhemoglobin; the red color ultimately originates from the iron atom in heme. If blood is drawn for a medical test, the dark red color can be seen; however, if it is exposed to oxygen in the air, it will turn bright red like arterial blood.

People mover

A people mover or automated people mover is a completely automated, grade-separated transit system. The term is normally used only to describe systems serving relatively small areas such as airports, downtown districts or theme parks, but is sometimes useful to considerably more complex automated systems. The term does not involve any particular technology, and a people mover may use technologies such as monorail, duorail, automated guide way transit or maglev. Propulsion may engage conventional on-board electric motors, linear motors or cable traction.

A few complex APMs deploy fleets of small vehicles over a track network with off-line stations, and supply near non-stop service to passengers. These taxi-like systems are more frequently referred to as personal rapid transit. Other complex APMs have related characteristics to mass transit systems, and there is no clear cut difference between a complex APM of this type and an automated mass transit system.

Business schools today try to impersonate the business setting in their academic programs by using student teams. As businesses more and more twisted to teams to work on projects and to solve troubles, MBA programs have converted a huge portion of course work from individual work to teamwork. Many masters of business administration programs now contain teambuilding training as team building workshops, or as a theme in managerial performance courses. Teams are formed mainly for the reason of one project in one course or by remaining together, working on multiple courses for months. In this competitive situation of Business administration programs, the collaboration of students in team building movements is often complicated. Students that take part in team activities find that working with someone else takes up a lot of educational time.

The business fundamentals are taught in every MBA program. Economics, finance, accounting, organizational behavior, marketing, and statistics are in the basic range for master of business administration programs. In business school these subjects are considered a foundation group of courses required for each and every candidate.

These core courses make up the first year of study in a two-year full-time program. In some programs, students who have a prior background in business can by pass some or all of the core courses on the basis of either a special examination or an evaluation of the undergraduate transcript. In some programs, students who have a previous backdrop in business can go around some or all of the foundation courses on the basis of either a special examination or an assessment of the undergraduate record.
