The purpose of this paper is to generate a wider acceptance of emergy analysis a decisionmaking tool in both the public and private sectors. The key to increasing the application of this powerful tool is to link it to productivity. Much of business and public policy decision-making is based on productivity and related efficiency measures. The productivity measures in common use today are narrow...

THE place for thyroidectomy in the treatment of disease of the thyroid gland is now well established. It has for long been practised by surgeons to relieve the pressure symptoms caused by simple non-toxic goitres, but it was not until the end of the first decade of this century that its use in the treatment of thyrotoxicosis was first described. Mayo, in 1907, reported on 110 operations for thy...

The main accelerator system of the proposed research facility FAIR is the two stage synchrotron complex SIS100/300, consisting of two separate synchrotron accelerators with equal circumferences. SIS100/300 shall provide beams of protons and heavy ions with high intensities and high energies. The existing GSI accelerators UNILAC and SIS18 shall serve as injector for SIS100/300. SIS100 will be de...

Biopsies of the external and sphincter taken from 24 male patients with haemorrhoids were subjected to examination using histochemical techniques. Fibre size (type 1 mean: 33 micrometers +/- 11.0 SD and type 2 mean: 47.9 micrometers +/- 15.0 SD) was increased when compared with control subjects. The distribution of muscle fibre types in these patients showed markedly greater type 1 fibre predom...

The "square" bacterium, first described by Walsby from brine collected at the Red Sea shore [A. E. Walsby, Nature (London) 283:69-71, 1980] was examined by electron microscopy. The cells appeared as flat rectangular boxes in scanning electron micrographs. In sections and freeze-fracture preparation, the edges looked more rounded. The thickness apparently remains constant as the cells grow and d...

Purified D-amino acid transaminase from Bacillus sphaericus catalyzes an alpha,beta elimination from the D isomer of beta-chloroalanine to yield equivalent amounts of pyruvate, chloride, and ammonia; the L isomer of chloroalanine is not a substrate for this transaminase. During the beta elimination there is a synchronous loss in enzyme activity; the Kinact for beta-chloroalanine was estimated t...
