Virtual laboratories in Molecular and Cell Biology - SDS-PAGE
A protein analysis laboratory using SDS-PAGE, western-blotting and endoprotease digestion. The programme includes a section on the theory of the techniques, a video demonstration in a real laboratory, and a series of questions which guide the students through the structural analysis of model proteins (3 are included). Students go to the virtual laboratory and devise their own experiments in order to determine the molecular weight, subunit composition etc of the proteins. Results (gels and blots)

5.4 Inspiratory drive

The supply of oxygen to tissues such as the heart, liver and WAT is, under euthermic conditions, invariably linked to and dependent upon local blood flow and pulmonary function. However, as we have already seen, under conditions in which blood flow is reduced to a trickle, the control of energy supply switches to local adaptations in the capillaries and tissue cells, including the oxygen affinity of erythrocyte haemoglobin, the supply and metabolism of respiratory fuels and the rate of protei

Low magnification SEM image of open cell polyurethane foam
If a gas is injected into a liquid it forms a cellular foam structure. When a thermoset prepolymer of low viscosity is foamed, the polymer can drain from the cell walls (driven by surface tension) before it sets at the cell edges, leaving an open-celled foam. The cell edges have three concave sides, giving rise to the tri-cuspid cross section visible at the bottom of this image. The average co-ordination number for the nodes (where struts meet) is four, giving tetrahedral junctions.

Open celled aluminium foam produced by infiltration of sintered salt
This is an inexpensive route for the production of open celled foams. It allows a high degree of control over cell size and shape, and results in relatively uniform morphology. The interconnectivity of pores can be controlled by varying the degree of sintering of the precursor.

Fe, C 1.0 (wt%), hypereutectoid alloy
This secondary electron SEM image shows the cementite delineating prior austenite grain boundaries with a thin layer. The amount of proeutectoid phase is very low, with the majority of the area being taken by the pearlite eutectoid. Again each pearlite cell has a different orientation with the ferrite phase being selectively etched.

Alporas' closed cell aluminium foam
Additions are made to molten aluminium or aluminium alloy to modify the melt viscosity and make it suitable for foaming. 1 to 3 wt% titanium hydride is then added to the melt, and this foams the melt by releasing hydrogen. The foamed melt solidifies to yield a closed cellular structure with an average cell size of 4.5 mm

Cell Differentials
Cell Differentials offers a visual dataset of white blood cells that gives students practice in developing strategies and techniques for the recognition of these blood cell types. Over 100 different cell images are randomly presented with feedback on successful identification. In traditional labs, the recognition of white blood cell types can be compromised by several factors. Developmental changes can make recognition difficult and some cell types exhibit similar features. Microscopy can be a

CuraÁao
CuraÁao is a computer program that simulates the sterile insect release method (SIRM) of pest population suppression, first conceived by E. F. Knipling (1955). The user can investigate the effects of several variables on the effectiveness of the method and discover what happens when some of the basic assumptions of the model are relaxed or violated in some way. The user should gain some understanding of the sorts of things that complicate the application of the technique in situations that are

Introduction to Glycolysis
Living cells can process certain sugar molecules, rearranging their atoms and this process can supply energy to the cell to power growth and other functions. This process is called glycolysis. Glycolysis evolved billions of years ago when there was no oxygen in the earth's atmosphere and it was therefore impossible for cells to gain energy from the oxidation of sugar molecules using oxygen. Later when oxygen was produced as a byproduct of photosynthesis cells evolved to utilise oxygen to oxidise
