Real-Time Devices At Practical Prices: Low Cost Laboratory Projects

It is a challenging task to develop a course in software methods which also includes a laboratory in which to experiment with the concepts. The challenge is made even more difficult when funds for such an endeavor are scarce. Practical and low-cost projects were implemented which give students hands-on experience with electronic devices while learning the software requirements of real-time syst...

Electrocardiogram: Some Practical Consequences

OKHAWA and his colleagues have provided histologic evidence that a lesion in the distal or branching portion of the His bundle, and thus actually within the ventricles, may produce complete atrioventricular (AV) block on the surface ECG associated with "AH" block on the His bundle electrogram (atrial impulses blocked proximal to the His deflection) and that this may be associated with an escape...

Some laboratory aids for a clinical laboratory.

N MANY INSTANCES the needs of a modern clinical laboratory are not completely satisfied through the usual commercial outlets. The item desired may be completely unavailable; it may be outside the budgetary limits of the laboratory; or a commercially available item may be unsatisfactory for the particular and peculiar needs of a clinical laboratory. The following discussion of clinical laborator...

Some practical guidelines for UV imaging in the protein crystallization laboratory

High-throughput imaging of protein crystallization experiments with ultraviolet (UV) light has recently become commercially available and can enable crystallographers to differentiate between crystals of protein and those of salt, as the visualization of protein crystals is based on intrinsic tryptophan fluorescence. Unfortunately, UV imaging is not a panacea, as some protein crystals will not ...
