WARNING TO WHOLESALE CHEMISTS.

In Chemists ’ Guide to Effective Teaching ,

The discussion of models and modeling in this chapter is based, in part, on the results of research on students’ understanding of quantum mechanics (Gardner, 2002) and research designed to probe students’ ability to visualize the rotation of organic molecules (Briggs, 2004). Our perspective on models and modeling has also been influenced by work in both physics education (Halloun, 1996) and mat...

Soft robotics for chemists.

In areas from assembly of machines to surgery, and from deactivation of improvised explosive devices (IEDs) to unmanned flight, robotics is an important and rapidly growing field of science and technology. It is currently dominated by robots having hard body plans—constructions largely of metal structural elements and conventional joints—and actuated by electrical motors, or pneumatic or hydrau...

The Chemists' War on Disease

For nearly a century and a half scientists have been studying ways of immunizing people against various diseases by artificial methods. Working mostly by trial and error they have devised reasonably safe vaccines and antisera for many diseases with a resulting spectacular decrease in mortality. T h e usual proceedure for vaccination is to inject the patient with the diseases-producing organisms...

Asymmetry In Wholesale ·

This study presents a new explanation ofasymmetric price behavior infood markets based on the presence of transactions costs, and provides evidence from a developing country. Price liberalization can in many cases be insufficient for efficient operation ofAfrican food markets. This is mainly due to the existence of significant transactions costs, caused by deficient infrastructure and informati...
