The determination of glyoxalase I phenotypes in human bloodstains

A method is described for the determination of glyoxalase I phenotypes in liquid blood and dry bloodstains. The frequencies of glyoxalase I phenotypes in various populations of S.E. England are included.     

The design of equipment and thermal routines for annealing glass particles

Equipment for annealing casework sized glass particles is described. Investigations were carried out using a simple muffle furnace, a temperature programmed furnace and a metal sample holder. Because they produced a uniform and reproducible thermal environment, best results were obtained from a combination of the temperature programmed furnace and the metal sample holder. Refractive index changes for window and toughened glass specimens were investigated and a simple, reproducible annealing routine for casework was devised.     

In vivo measurements of facial tissue thicknesses in American caucasoid children

Ultrasonic determinations were made of facial tissue thicknesses in 50 healthy American caucasoid children, ranging in age from 4 to 15. Twenty measurements were taken at sites along the median, right sagittal, and right lateral planes. A static scanner was used in the B-mode. Three measurements significantly increased with age, the mid-philtrum (rs = 0.43, p less than 0.01) in females, the mental sulcus (rs = 0.30, p less than 0.05) in males, and the frontal eminence (rs = 0.32, p less than 0.05) in both sexes. Moreover, 25% of the measurements, while not statistically significant, decreased with increasing age. These data provide a basis for facial reproductions in caucasoid children.     

Hypernatremia due to amniotic fluid embolism during a saline-induced abortion

A case of fatal amniotic fluid embolism leading to hypernatremia during a hypertonic saline-induced abortion is reported. This sequence of events has not, to our knowledge, been previously reported. Hypernatremia as a diagnostic aid for amniotic fluid embolism is discussed.     

REGULATORY ENFORCEMENT: An Economic Study of the British Factory Inspectorate

The British Factory Inspectorate is the body responsible for enforcing occupational health and safety legislation in the manufacturing industries. The concept of economic efficiency is used to link the compartmentalized disciplines involved in regulation. Many enforcement practices in social regulation can be seen as attempts to minimize social costs of disobeying regulations subject to institutional, political, and budgetary constraints.
