Illustration of neural net in computer application

Neural network. Diagrammatic illustration of the pathway of information in a neural network, useful in computer applications. At centre right, input data (red arrow) is received by parameters (blue spheres), then flows on to neurones (red spheres) where data is processed, and the response (blue spheres) issue the combined output (blue arrow). In information technology a neural network tries to approach the complexity and power of an animal's nervous system, using the same principals of stimulus-response. But in computer application, animal nerve receptors, nerve fibres & cells, are replaced by input devices, microprocessor chips and very rapid computer analysis and output

Coxiella burnetti bacterium dividing

Coxiella burnetti. False-colour transmission electron micrograph (TEM) of the rickettsia-like bacteria Coxiella burnetti. Here, the organism is dividing in two, with cell contents duplicated. Coxiella burnetti is the cause of an influenza- like febrile illness known as "Q" fever. It is highly infectious, usually including patchy pneumonic consolidation. Hepatitis & endocarditis may also occur. Q fever is transmitted to humans via sheep, goats and cattle. Human infection is by inhalation of dust or droplets contaminated from the excreta of infected animals, or by ingestion of infected milk. Treatment is with antibiotic drugs.
