Options for informal environmental management : the agricultural industry highlighted
Discussions are frequently found in the environmental press regarding the possible advantages to an organisation should they implement a formal environmental management system such as BS 7750, ISO 14001 and the EC ...
Scoring and ranking farmland conservation activities to evaluate environmental performance and encourage sustainable farming
The University of Hertfordshire, in collaboration with two UK agricultural establishments ADAS and IACR-Rothamsted are developing a computerised decision support system for environmental management of arable agriculture. ...

The Energetic Cost of Activation of White Muscle Fibres from the Dogfish Scyliophinus Canicula
The energetic cost of activation was measured during an isometric tetanus of white muscle fibres from the dogfish Scyliorhinus canicula. The total heat production by the fibres was taken as a measure of the total energetic ...
Serologically based diagnostic and quantification tests for nematodes
Plant parasitic nematodes are important plant pests which are difficult to identify and quantify. Serologically based techniques offer new ways to identify and quantify these parasites. Several factors need to be considered ...
Adhesion of Pasteuria penetrans to the cuticle of root-knot nematodes (Meloidogyne spp.) inhibited by fibronectin : A study of electrostatic and hydrophobic interactions
Pasteuria penetrans is a bacterium with the potential to control plant-parasitic nematode populations; the mechanism of spore adhesion, however, is poorly understood. Attachment assays were performed in media supplemented ...
Environmental Management in Agriculture : An expert system approach
The development of quantitative measures for self-assessment of the environmental performance of farming enterprises is described. A rule-based expert system approach is adopted based on well established sources of guidance. ...
Use of neural networks in brain SPECT to diagnose Alzheimer's disease
The usefulness of artificial neural networks in the classification of Tc-99m-HMPAO SPECT axial brain scans was investigated in a study group of Alzheimer's disease patients and age-matched normal subjects. Methods: The ...
Unchained memory: Error patterns rule out chaining models of immediate serial recall
Many models of serial recall assume a chaining mechanism whereby each item associatively evokes the next in sequence. Chaining predicts that, when sequences comprise alternating confusable and non-confusable items, confusable ...
