Transient absorption spectra and kinetics in the 470-650 nm region were recorded for lycopene, P-carotene and zeaxanthin, all carotenoids with 11 conjugated double bonds, in two solvents with different polarity. Analysis of the red wing of the carotenoid SI-S, transition revealed presence of a pronounced shoulder at early delay times. The kinetics recorded at this low-energy shoulder of the SI-S,
In a group of 36 patients, 18 women and 18 men, results for the Spiral Aftereffect Technique (SAT) and the Defense Mechanism Technique modified (DMTm) after recovery from depression (at follow-up) were related to results for both techniques during the acute phase of depression, and to seven symptom dimensions (tension, inertia, dissociation, hypochondria, nondivertability, heredity and suicidal th
A polyion-surfactant ion complex salt, cat-HECDS, has been synthesised, consisting of cationic hydroxyethyl cellulose w th dodecylsulfate counterions. Ternary phase diagrams have been established for aqueous mixtures of cat-HECDS with either the conventional surfactant NaDS or the polyelectrolyte cat-HECCl. Such mixtures represent the simplest possible aqueous mixtures of oppositely charged polyme
An outbreak of gastroenteritis affecting 158 of 219 (72%) guests and employees at a hotel is described. Food served at the hotel restaurant is believed to have been the source of the outbreak and to have been contaminated by sick employees working in the restaurant. A secondary attack rate of 22% was seen involving 43 persons in all. In stool specimens from seven of eight patients, Norwalk-like vi
Context. Extremely metal-poor (EMP) stars preserve a fossil record of the composition of the ISM when the Galaxy formed. It is crucial, however, to verify whether internal mixing has modified their surface composition, especially in the giants where most elements can be studied. Aims. We aim to understand the CNO abundance variations found in some, but not all EMP field giants analysed earlier. Mi
The inflammation of the lungs in chronic obstructive pulmonary disease (COPD) is characterised by increased numbers of macrophages, neutrophils and T-cells. Decline in lung function in these patients has been correlated to the number of CD8+ T-cells present in the lung as well as to a decline in the ratio of CD4+/CD8+ T-cells. Although systemic components are likely to be present, circulating lymp
5-HT1D (but not 5-HT1B )-receptor immunoreactivity (i.r.) can be detected on trigeminal fibres within the spinal trigeminal tract of the human brainstem. The present study used immunohistochemical and morphometric techniques to determine the proportions of trigeminal fibres expressing substance P, CGRP or 5-HT1D -receptor immunoreactivities. Co-localization studies between 5-HT1D -receptor and sub
Meteorological investigations were carried out in forests in the southwestern part of the Swabian Alb (SW Germany) to analyze the influences of exposition and silvicultural treatment on the microclimate within various stands of beech (Fagus sylvatica L.). The measurements were taken as part of an interdisciplinary project on the effects of climate and forest management on structures and processes
The influence of standard heparin or low molecular weight (LMW) heparin on healing of abdominal wounds and colonic anastomoses was studied in rats. Subcutaneous injection of 1 XaI U/g b.w. of standard or LMW-heparin or 0.5 ml physiologic saline was given 12 hours preoperatively and daily for 3 or 7 days postoperatively. Breaking strength of the abdominal wound and the anastomosis was measured, as
It is common to use activities of daily living (ADL) rating scales to identify the impact of health problems such as diseases, impaired eyesight or hearing on daily life. However, for various reasons people with health problems might feel hindered in daily life before limitations in ability to perform ADL have occurred. In addition, there is sparse knowledge of what makes people feel hindered by h
OBJECTIVE: To estimate the incidence and describe characteristics of preventable adverse drug events (pADEs) in ambulatory care. DATA SOURCES: Studies were searched in PubMed (1966-March 2007), International Pharmaceutical Abstracts (1970-December 2006), the Cochrane database of systematic reviews (1993-March 2007), EMBASE (1980-February 2007), and Web of Science (1945-March 2007). Key words inclu
In this thesis, we develop and examine decision models intended for traffic engineering analysis of multiservice networks. Two important issues are addressed, namely call admission and routing control in multiservice broadband networks, and overload control in distributed-memory systems. Multiservice broadband networking generally refers to the ability to handle widely disparate traffic streams s
It is commonly accepted that among recent fishes the lungfishes are the closest relatives of the tetrapods. According to this hypothesis, the tetrapods, lungfishes and coelacanths constitute a group of specialized fishes (Sarcopterygii) to the exclusion of other bony fishes. Here, we describe basal relationships among gnathostome (jawed) vertebrates as reconstructed by analysis of complete mitocho
The medical device industry is a constantly growing domain which makes use of more and more software products. Given the importance to this industry of dependable software components, rigorous software engineering techniques would seem to have an important role to play. However, in a recent survey of the industry we found a lower than expected rate of adoption of certain sound software engineering
Reversed phase continuous full filling capillary electrochromatography with electrospray ionisation mass spectrometric detection was performed with highly sulphated poly [styrene-co-(lauryl methacrylate)-co-(divinylbenzene)] nanoparticles. The nanoparticles that contained a hydrophobic core and a hydrophilic surface were prepared in a one step synthesis using soap free emulsion polymerisation. By
