A model for an electric infrared (IR) heater has been developed. The model includes non-grey radiative heat transfer between the different parts of the IR heater, as well as conduction in reflector material and convective cooling of surfaces. The geometry is simplified into one dimension. Using IR module voltage, as the only input, the model predicts the temperature of heater components and coolin

The aim of this study was to test the hypothesis that low intensity exercise-induced low frequency fatigue is caused by failure of excitation-contraction coupling. Changes in knee extension torque at 5, 10, 15, 20 and 50 Hz electrical stimulation of quadriceps muscle in ten healthy, young, male subjects were recorded during 20-min voluntary exercise followed by 60-min recovery. In seven of the ten

1. Adrenaline-stimulated lipolysis in adipose tissue may increase with training. The rate-limiting step in adipose tissue lipolysis is catalysed by the enzyme hormone-sensitive lipase (HSL). We studied the effect of exercise training on the activity of the total and the activated form of HSL, referred to as HSL (DG) and HSL (TG), respectively, and on the concentration of HSL protein in retroperito

The opening article of this issue is intended to provide a review of some relevant topics of the mathematical theory of water waves that have recently received considerable attention in the research literature. We also provide a brief discussion about the content and contribution of the articles that make up this issue.

We showed earlier that over-expression of protein kinase C (PKC) epsilon induces neurite outgrowth. The effect is mediated by a region (PKC epsilon PSC1V3) encompassing the pseudosubstrate, the two C1 domains and part of the V3 region, and is independent of the catalytic activity of the enzyme. In this region, residues immediately N-terminal of the C1b domain are crucial for neurite outgrowth. How

A conscious therapeutic approach was used combining methods in physiotherapy with psychological awareness to re-educate nine transfemoral amputees during 10 months in outdoor environments. All were rehabilitated trauma or tumour cases, mean age 33 years, and had worn their prostheses for more than 18 months. The method aimed at integrating the prosthesis in normal movements and increasing body awa

Albatrosses are known for their extreme navigation performance enabling them to locate isolated breeding islands after long-distance migrations across open seas. Little is known about the migration of young albatrosses and how they reach the adults' navigation and foraging skills during the period of immaturity lasting several years and spent permanently flying across the open ocean. We tracked by

The interactions of sodium dodecyl sulfate (SDS) with chemically cross-linked gels of ethyl(hydroxyethyl) cellulose (EHEC) were studied. Above the so-called critical association concentration (cac), binding of SDS gives rise to an increased swelling of the EHEC gels. The binding of SDS to the gels was measured with flame emission analysis of the sodium ion. The self-diffusion of the surfactant ion

Previous studies have shown that the functional efficacy of intrastriatal transplants of fetal dopamine (DA) neurons in the rat Parkinson model depends on their ability to establish a new functional innervation of the denervated striatum. Here we report that the survival, growth, and function of the grafted DA neurons greatly depend on the severity of the lesion of the host nigrostriatal system. F

Popular Abstract in Swedish Patientföreningarnas (PF) betydelse för sina medlemmar och för hälso- och sjukvårdssystemet har ökat och kommer sannolikt att öka. Denna avhandling studerar PF för cancerpatienter (PFCP) med avseende på utbredning, funktion, aktiviteter, och samverkan med hälso- och sjukvården utifrån föreningarnas och medlemmarnas erfarenheter. Studie I idenitifierar och beskriver svenPatient associations (PAs) have an increasing impact for their members and for the health care system. This thesis studies PAs for cancer patients (PACPs) ? currently with over 20 000 members in Sweden ? regarding coverage, activities, and collaboration with the health care system with specific reference to the members? experiences. Study I identified and characterized Swedish PACPs, their activit

We investigated whether dorsal hindbrain and/or peripheral cocaine- and amphetamine-regulated transcript peptide (CARTp) acts to suppress gastric emptying of a caloric stimulus. Furthermore, effects of dorsal hindbrain CARTp on sucrose consumption and licking microstructure was studied, as well as the possible contribution of corticotropin-releasing factor (CRF) receptors to mediate effects of CAR

In the modified SX-700 monochromator installed at beam line I411, the focusing before the exit slit is achieved by a plane elliptical mirror. Like in the original SX-700 design, the resolution is mainly limited by the slope errors of the focusing mirror. A simple method to improve the resolution is to replace the focusing mirror by one with smaller slope errors. The effects of replacing the refocu

BACKGROUND: Infusion of sulphated cholecystokinin-8 (CCK-8S) in rats transiently increased the proliferation of pancreatic acinar cells, whereas the CCK-A receptor antagonist devazepide decreased such proliferation. This effect ceased after 3 days. CCK-8S or devazepide injected twice daily induced a persistent effect on the cell proliferation involving the major cells of the exocrine pancreas. The

Purpose: To evaluate the characteristics of polycystic compared to normal ovaries using three-dimensional (3-D) power Doppler ultrasonography. Methods: We recruited 42 volunteers, all of whom were commencing IVF treatment. Each patient was examined in the cycle preceeding the start of drug therapy during the late follicular phase. IF eight or more subcapsular follicles of 2-8 mm in diameter in one
