A time-related deterioration in male reproductive function caused by exposure to endocrine disrupters, including persistent organochlorines (POCs), has been hypothesized. In animal studies, POCs were found to have adverse effects on male reproductive function. However, little is known about the impact of POC exposure on reproductive parameters in men. In a study of 305 young Swedish men 18-21 year

A discussion of what constitutes a good human being.

Out of Quality of Service reasons, higher priority shall in cellular networks be assigned to ongoing connections than to new call attempts. This can be accomplished through reserving a portion of the bandwidth assigned to a cell exclusively for high priority connections. A low priority call is only admitted to a cell if the unoccupied bandwidth in the cell following the acceptance of the call exce

OBJECTIVE: To illuminate the lived experience of women facing the threat of lossing their newborn child and then experiencing the reality of their infant's death. STUDY DESIGN: Sixteen women were interviewed approximately 2 years after the death of their infant using a hermeneutic phenomenological approach. FINDINGS: The main theme was ambivalent transition into motherhood. The women went through

The distribution of neuropeptide Y (NPY)-immunoreactivity was investigated in the rabbit maxillary sinus and adjacent ganglia. A moderate supply of NPY-containing nerve fibers occurred around seromucous glands and a denser supply around small blood vessels. Only a few immunoreactive nerve fibers were seen beneath the epithelium. Double immunostaining showed that vasoactive intestinal peptide (VIP)

A distillation unit has been designed for a capacity of 73 t/h of condensate and for at least 90% recovery of the contaminating organics. This unit consists of three columns: a primary stripper to remove volatile organics and two upgrading columns to purify the methanol and furfural byproducts. Three different energy-saving alternatives for satisfying the energy requirements have been studied: ut

This thesis is an empirical study of how positioning is achieved in interactional Swedish. Positioning has previously been described in terms of epistemic modality, interpersonal positioning, stanceand speech act adverbials. The aims of the study are, firstly, to identify what linguistic resources are used to achieve positioning in interaction. A second aim is to describe where in the turn-con

La structure de la viande hachée évolue au cours de la cuisson, ce qui a une influence sur les transferts de chaleur et de matière. L'étude a porté sur la friture de steaks hachés de 10 mm d'épaisseur et de 3 à 10 cm de diamètre, provenant de 4 sortes de viande. La cuisson avait lieu entre deux plaques chauffées à 100, 150 ou 175 °C. Elle faisait passer le produit depuis l'état congelé à -20°C jus

Bioelectrocatalytic oxidation of theophylline was studied at gold and graphite electrodes modified with microbial theophylline oxidase (ThOx), a multi-cofactor redox enzyme capable of selective oxidation of theophylline. Gold electrodes were additionally modified with self-assembled monolayers (SAMs) of (-OH)- and (-NH2)-terminated alkanethiols of different chain lengths, to achieve compatibility

The basement rocks of southern Sweden were deeply weathered in Late Triassic through Cretaceous times, and possibly even earlier. Sub-Mesozoic saprolites formed, presumably due to long-term warmth and humidity, in conjunction with decomposition of abundant organic matter and subsequent infiltration of acidic water. The upper parts of the weathering profiles were subjected to intense leaching and k

The SEA coupling and dissipation loss factors are determined in-situ from Complex Modulation Transfer Functions, CMTF:s, based on measured impulse-responses. A quotient of CMTF:s is least-square curve-fitted to a SEA model and the SEA loss factors are determined from the results of the curve-fit. A two subsystem SEA model with time-varying power is considered. In the frequency domain, power-energ

A reliable and inexpensive device for measuring gas with low flow rates is described. The device works based on the principle of liquid displacement and is able to measure flows from 1 to 950 ml(.)h(-1). It also has improved counting logic and data processing capacity to avoid miscounting and provide a friendly interface for data display. (C) 2003 Elsevier B.V. All rights reserved.
