The closteroviruses, capilloviruses and other similar viruses : A short review
(1993-08)
The closteroviruses and capilloviruses are diverse groups of structurally similar, flexuous, filamentous plant viruses. However, because of a lack of information of other than a morphological nature the taxonomy of these ...
Genetic modification and the environment : EC directives and the genesis of UK regulation
(1993-08)
The rapid advances in bio-technology that have been witnessed in recent years have been matched by an increase in concern associated with both the moral dimensions and the possible environmental impacts of genetically ...
Depression of tetanic force induced by loaded shortening of frog muscle fibres
(1993-07)
1. Single fibres isolated from the anterior tibialis muscle of Rana temporaria were allowed to shorten against a high load during a 2.5-4.0 s fused tetanus (1-3 degrees C) and the maximum force produced at the short length ...
Reaction-mechanisms for astrophysically relevant nuckear processes
(1993-07)
The different reaction mechanisms and models applied to nuclear reactions at thermonuclear energies are discussed. As an example we consider the reaction Li-8(alpha,n)B-11.
The high-force region of the force-velocity relation in frog skinned muscle fibres
(1993-07)
The force-velocity relation has been studied during calcium-induced contracture of chemically skinned fibres from the semitendinosus muscle of Rana temporaria with special interest focused on the high-load region. The ...
Interactions of Ostertagia species with their bovine and ovine hosts
(1993-07)
Ostertagia spp. affect their hosts in several complex interactions involving structural, biochemical, hormonal, nutritional and immunological mechanisms. Following infection with Ostertagia spp. the specialised secretory ...
A refutation of Karasek's demand – discretion model of occupational stress with a range of dependent measures.
(1993-07)
Karasek's (1979) demand–discretion model of occupational stress has been highly influential but has been criticized as confounding social class variables (Payne and Fletcher, 1983), ignoring the curvilinearity of relationships ...
