For anhydrobiotic metazoans the rate of desiccation is an important factor influencing the probability of survival in a dry anhydrobiotic state. Formation of animal aggregations, in which the exposed body surface area of individual animals is reduced, represents one way to reduce the rate of evaporation. Such aggregations have earlier been documented in e.g., nematodes. We experimentally evaluate
To explore the molecular mechanisms responsible for the variation in smooth muscle contractile kinetics, the influence of MgATP, MgADP, and inorganic phosphate (P(i)) on force and shortening velocity in thiophosphorylated "fast" (taenia coli: maximal shortening velocity Vmax = 0.11 ML/s) and "slow" (aorta: Vmax = 0.015 ML/s) smooth muscle from the guinea pig were compared. P(i) inhibited active fo
The surface-to-bulk intensity ratio in Auger electron spectra has been studied in comparison with core-level photoelectron spectra using free argon clusters of sizes ranging over two orders of magnitude. Enhanced surface sensitivity is observed in L2,3M2,3M2.3 Auger electron spectra compared to 2p photoelectron spectra where electrons of similar kinetic energies were recorded. This is discussed in
Although most institutions offer some kind of follow-up to patients operated on for colorectal cancer, its value with respect to prolonged survival has been challenged. However, improved results of liver surgery and chemotherapy make it reasonable to assume that a follow-up programme leading to detection of more asymptomatic recurrences would result in improved survival. Liver metastases and extra
The absorption of hydrogen chloride by spent desulfurization sorbents containing calcium carbonate, calcium oxide and calcium hydroxide was investigated. The experiments were carried out in a fixed-bed reactor in two temperature ranges: 423-523 K for slaked lime and 673-873 K for limestone and quicklime. The spent Ca-based sorbents can still react with hydrogen chloride, and after calcining and sl

Lifetimes of high spin states in the nucleus Tc-90 have been measured via the fusion evaporation reactions Ni-58(Ar-36, 3pn)Tc-90 at 140 MeV and Ni-58(Cl-35, 2pn)Tc-90 at 120 MeV beam energy. The OSIRIS spectrometer as well as a new neutron-gamma-coincidence setup were used to measure lifetimes in the 10(-12) - 10(-9) s range by the recoil distance Doppler-shift method. By means of gamma-multiplic
Background/Aims: Endothelin-1 (ET-1) has been implicated in pathologic remodelling and tissue repair processes in the heart. We investigated the effects of ET-1 on growth and collagen synthesis responses in cardiac fibroblasts isolated from human hearts. We also studied the receptor subtype(s) mediating such responses and the factors regulating their expression. Methods: Fibroblasts were isolated
Many natural scientists foster the idea of a degrading environment, caused by over-exploitation of the resources, being the cause of famine and poverty in Africa. In accordance with this, policies aimed at restoring the environment are formulated. This article analyses the main causes of famine, i.e. drought, desertification and the food market, with examples from the 1984-85 famine in the Sudan.
Denna skrift redovisar sjutton exempel på sunda hus - nio daghem och åtta skolor där brukarna upplever ett tillfredsställande inomhusklimat. Samtliga byggnader har nyligen uppförts eller byggts om.

Two series of tests with wall lining materials in an extensively equipped model scale room have been carried out. The dimensions of the room were 1.2 X 0.8 X 0.8 m³. In test series I the wall lining materials were mounted on three walls and in the ceiling. This test series comprised thirteen different materials. In test series I1 ten different materials were tested. They were mounted on the walls
Goodpasture's syndrome is an autoimmune disease characterized by pulmonary hemorrhage, glomerulonephritis, and antiglomerular basement membrane (GBM) antibodies. We have studied a rat model with chimeric proteins (CPs) consisting of portions of the nephritogenic non-collagenous domain of alpha3 type IV collagen (alpha3(IV)NC1) and non-nephritogenic alpha1(IV)NC1. CPs with aminoterminal alpha3 that
Validated outcome instruments were used to compare treatment outcomes of carpal tunnel syndrome (CTS) in workers' compensation and non-workers' compensation patients. A self-administered questionnaire consisting of the generic Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) and the disease-specific Carpal Tunnel Syndrome Instrument was mailed to 277 patients randomly selected from
