Packaging has a major impact on the activities performed in a logistical value chain. Packaging can improve or decrease the efficiency of the outbound logistics process. It is therefore important to consider the activities and the value that they add to the overall process. ROL International is a Swedish store interior manufacturer that design‚ produce and distribute their products on a global basis. One of their basic products is the shelf concept. ROL wants to improve their efficiency and consider

Ownership of Bodily Fluids and Organs: Do we have the right to sell Organs and Fluids? The advancement of modern technology and our continual progress in medical sciences have made it necessary to debate this topic. There are many cases where it is unclear as to whom has the property rights of bodily fluids‚ cells‚ or organs. These questions of ownership tend to surface in cases where these products are no longer located within a person’s body. The necessity to delegate ownership

RESEARCH PAPER ON BIOLOGICAL ACTIVITY OF ACTINOMYCETES ................ ABSTRACT: The microorganisms are ubiquitous in nature. They are found in probably every environmental condition present on earth. Actinomycetes were originally considered to be an intermediate group between bacteria and fungi but now are recognized as prokaryotic organisms with high G+C (>55%) content in their DNA. Our project aim is to evaluate some biological activities of Actinomycetes like:

Midterm Exam II Solution‚ ME 342 Fluid Mechanics (Spring 2013) 1. Consider a steady‚ incompressible‚ y=+h b viscous flow of viscosity due to y a pressure gradient x inside a channel of two fixed u=u(y) plates at a distance of 2h‚ as shown in the figure. Neglect a gravity effect. The channel width y=h b is W and it is very long compared to the channel length L (i.e.‚ W>>L) so that it is still valid to assume that the channel flow is a two-dimensional plane flow ( ) and an axial flow (v = w = 0)
