Inexpensive microcomputer networking for laboratory research

Osmosis: a microcomputer laboratory teacher.

A computer simulation of osmotic processes has been developed. Several experimental setups are graphically simulated and may be freely selected by the user. The simulation analyzes the basic factors which determine the osmotic pressure and volume flow of a solution (e.g. concentration, temperature, activity coefficient, Staverman's coefficient and external pressure). The program was written in ...

Biochemical laboratory management with a microcomputer

An inexpensive, microcomputer-based, video densitometer for quantitating thin-layer chromatographic spots.

An inexpensive video densitometer based on an Apple II microcomputer using commercially available components was developed. The device was used to quantitate charred lipid and colored spots on thin-layer chromatography plates. The method is useful for lipid samples weighing 0.1 to 4 micrograms on high-performance plates and 1 to 20 micrograms on ordinary plates. The software automatically corre...

Potatoes: Source of Laboratory Reagent for Human Platelets Research

Irish potatoes is rich in carbohydrate, with varied glucose levels. It is also a very good source of apyrase, an enzyme used for platelet storage. The aim of this study was to explore Irish potatoes as an easily available source for apyrase extraction and purification. Apyrase was extracted from 5 Kg of Irish potatoes. Platelets were derived from 5-10 ml of human whole blood and G6PD activity w...

53 Environments for a Networking Laboratory

TinkerNet, TinkerNet2, and VDE (Virtual Distributed Ethernet) were all developed as low-cost platforms for teaching bottom-up, hands-on networking at the undergraduate level. In the original TinkerNet "throw away'' PCs, cheap components, and free software were used to create a networking laboratory. TinkerNet was created as a software-only system based on User-Mode Linux (UML). VDE provides a d...
