Simple and computer attractive models for calculating radiation properties are needed. This paper considers recent models available in literature, and provides suggestions how to improve the calculation performance of the existing ones.
1. This paper describes, in quantitative terms, the in vivo effects of two selective ETB-receptor agonists (IRL 1620 and BQ 3020) on vascular resistance (tone) in the following consecutive sections of the vascular bed of sympathectomized cat skeletal muscle: large-bore arterial resistance vessels (> 25 microns), small arterioles (< 25 microns) and the veins. The effects on capillary pressure trans
The chemical composition of plena, sphalerite and pyrite surfaces has been analysed after dry and wet grinding, and after treatment with water and aqueous solutions of potassium alkylxanthate by means of Diffuse Reflectance Infrared Fourier Transform (DRIFT) spectroscopy. The total metal concentration in the aqueous phase has been determined by means of atomic absorption spectrophotometry. The rea
Background: The primary sensory cortex (S1) in the postcentral gyrus is comprised of four areas that each contain a body map, where the representation of the hand is located with the thumb most laterally, anteriorly and inferiorly and the little finger most medially, posteriorly and superiorly. Previous studies on somatotopy using functional MRI have either used low field strength, have included a
Effects of smoking on breast cancer risk remains controversial. Tar products have been claimed to increase risk, antioestrogenic effects to reduce risk. Another possibility is that associations to smoking have been confounded by diet. The increasing incidence of breast cancer from 1960 to 1994 in Sweden is parallel to that of lung cancer and the increasing proportion of female smokers. The inciden
Double-contrast barium enema has a reduced sensitivity in patients with severe sigmoid diverticulosis. Therefore a carboxy methyl cellulose enema was employed after the conventional double-contrast examination in 15 patients with sigmoid diverticulosis. A significant increase in lumen diameter and a superior removal of barium residue from the diverticula facilitated the interpretation of the sigmo
Lung surfactant (LS) is an extra-cellular lipid-protein system responsible for maintaining low surface tension in the lung and alveolar stability. Serum proteins cause dysfunction of this material, e.g. in adult respiratory distress syndrome (ARDS). BLES is a clinically used LS consisting of most of the lipids and associated proteins from bovine lung lavage. Aqueous phases of BLES at 30% and 70% h
Background and Objectives. Human leukocyte elastase, proteinase 3 and cathepsin G are neutrophil granule proteins belonging to the hematopoietic serine protease superfamily. In addition to their established roles in inflammation, they have recently been implicated as regulators of granulopoiesis and mediators of apoptosis. We set out to characterize the individual biosynthetic profiles of these pr
In the dinuclear title compd. [FePtCl2(C17H14P)(C21H20O2P)]CH2Cl2, the PtII atom has a square-planar geometry and the ferrocenyl-phosphine ligands are staggered at a 24.7 (2) angle.
Two different techniques, Doppler-free saturation spectroscopy on a hollow-cathode discharge and fluorescence spectroscopy on a collimated atomic beam produced from a hollow-cathode discharge, have been used for high-resolution laser-spectroscopy measurements on the 3d10 4p and 5p states in neutral Copper. The relative merits of the two techniques are discussed.
1) Toxic algal blooms widely affect our use of water resources both with respect to drinking water and recreation. However, it is not only humans, but also organisms living in freshwater and marine ecosystems, that may be affected by algal toxins. 2) In order to assess if cyanobacterial toxins affect the composition of natural zooplankton communities, we quantified the temporal fluctuations in mi

Popular Abstract in Swedish Svensk sammanfattning (Swedish Summary) Inflammatoriska sjukdomar i luftvägarna tillhör ett av de vanligaste skälen till ohälsa. Astma, både allergisk och icke allergisk, kan debutera redan under de första levnadsåren och kan på lång sikt ge kroniskt nedsatt lungfunktion. Bland medelålder's och äldre personer är kronisk obstruktiv lungsjukdom (KOL) vanligast, oftast etEndothelin-1 (ET-1) is an extremely potent smooth muscle spasmogen well known from the vascular system but also active within the airways. The importance of its proinflammatory and co-mitogenic properties has become increasingly evident, the endothelin system also having been shown to mimic the signal features of asthma, COPD and other pulmonary diseases. The present thesis concerns the role of th
The aim of this thesis is to investigate the functions of the word "tot" 'whole; each; all' in old and modern Romanian, by studying the syntax, morphology and semantics of this word as part of or in combination with a noun phrase (NP). An attempt is made to find out the status of "tot" in a classification of numerals, articles and adjectives. The present work consists of four separate studies (i.
This dissertation is about men as a minority in a female profession, that of university- trained social worker. The aim is to illuminate the relationship between work and gender on the basis of career, minority, and masculinity in the profession of social work. By means of questionnaires sent to all the men who trained as social workers in Lund 1980–1985 (the 1980s generation) and 1993–2003 (the 1
