The effect of geometric factors on insulation was calculated mathematically for standing humans. It was found that internal radiative heat transfer in an ensemble was significant for insulation, that intrinsic clothing insulation is a useful concept only for indoor climates, and that shape plays a minor role. The literature agrees closely on...

In a case-control study in The Netherlands, we observed a significantly lower consumption of fermented milk products (predominantly yogurt and buttermilk) among 133 incident breast cancer cases as compared to 289 population controls (mean ± SD among users only, 116 ± 100 versus 157 ± 144 g/day; P<0.01). The age-adjusted odds ratio of daily...

Two experiments were conducted which tested the effect of two different types of cues on the allocation of attention in the visual field. Subjects responded to a target appearing either 6.5° to the right or to the left of fixation in a field with small randomly positioned line segments. The target form was either a circle or diamond in which a...

This study was designed to investigate the relation between fatty acid consumption, total plama cholesterol and neuroendocrine response to exposure to stress, factors thought to play a role in the development of coronary heart disease. For this purpose 32 apparently healthy male volunteers were classified on the basis of their plasma cholesterol...

For a period of 6 weeks, 76 healthy male volunteers consumed during their daily main meal the contents of one tin (~ 135 g) of either fish (mackerel) paste or meat paste. Fibrinolytic parameters were determined in plasma samples obtained at the beginning and at the end of the experimental period. No changes were found in plasminogen, α2...

Driver behaviour will partially be a function of the cognitive schemata by which drivers represent features, functions and operations of traffic system components. This paper uses the Repertory Grid Technique to address the questions: (1) How do drivers internally represent different categories of road? (2) How are those representations mapped...

The time-to-line-crossing (TLC) concept has been used as a time-related measure to describe driving strategy. The purpose of this research is to analyze whether TLC might enlarge our understanding of the relationship between vehicle handling characteristics and a driver's looking and lateral control strategy in a straight-lane-keeping task....

The vitamin B6 status of women suffering from premenstrual symptoms (PMS, n = 19) and a group of matched controls (n = 19) has been investigated. The women volunteering in the study were selected on strictly defined criteria. Several biochemical parameters of the metabolism of vitamin B6 and tryptophan were studied in blood and urine samples...

Two groups of male and female Syrian golden hamsters, of which the trachea was severely injured by electrocoagulation, received 6 weekly intratracheal instillations of benzo[a]pyrene (BaP) + ferric oxide in saline or saline alone. Two comparable groups of hamsters were similarly treated but had an undamaged trachea. The experiment was terminated...

Contents of bile acids and lipids, as well as rates of triglyceride synthesis, were determined in isolated hepatocytes from control or cholestyramine-fed rats (denoted below as "control" or "treated" hepatocytes, respectively). During a 3-hr incubation period, total bile acid production was markedly higher in "treated" cells than in "conrol"...

Anaesthetized, atropinized rats were posioned with 6x LD50 soman (1,2,2-trimethylpropyl methylphosphonofluoridate). Purified acetylcholinesterase, injected i.v. 75 min later, was rapidly inhibited, presumably by soman stored in a 'depot' from which it was gradually released. Existence of a depot is supported by the effect of a soman-simulator (...
