Extended X-ray absorption fine structure measurements have been used to characterize, at the atomic level, the thermally induced structural relaxation of InAs amorphized by ion implantation. Our results are consistent with a relaxation mechanism mediated by point-defect annihilation with concomitant reduction in both chemical and structural disorder. Though relaxation yields a decrease in chemical

We have applied cell-attached capacitance measurements to investigate whether synaptic-like microvesicles (SLMVs) undergo regulated exocytosis in insulinoma and primary pancreatic beta-cells. SLMV and large dense-core vesicle (LDCV) exocytosis was increased 1.6- and 2.4-fold upon stimulation with 10 mmol/l glucose in INS-1 cells. Exocytosis of both types of vesicles was coupled to Ca(2+) entry thr

A study of the ambitions of the managers at AB Robertsfors Bruk and their impact on courses of action in the development of wage policy and social arrangements in the community of Robertsfors during the period 1925-35.This study deals with employer actions during a period of both internal and external change to the organization. The main focus is in the areas of wage policy and social arrangements

The Gaussian curvature of a two-dimensional Riemannian manifold is uniquely determined by the choice of the metric. The formulas for computing the curvature in terms of components of the metric, in isothermal coordinates, involve the Laplacian operator and therefore, the problem of finding a Riemannian metric for a given curvature form may be viewed as a potential theory problem. This problem has,

Background. The aim of this study was to investigate the occurrence and appearance of the anastomosis between the two umbilical arteries in placentas from infants small for gestational age (SGA). Methods. The arterial systems of 64 placentas from singleton pregnancies resulting in SGA infants were visualized by angiography. The method allowed study of the anastomosis between the umbilical arterie

Popular Abstract in Swedish Det är idag välkänt att patienter med kärlsjukdom i benen har en rad problem som kan påverka deras livskvalitet. Studier har visat att de vanligaste problemen för dessa patienter är trötthet, smärta och begränsad rörelseförmåga. Det är även välkänt att en lyckad kärlkirurgisk behandling ger en snar förbättring av livskvaliteten. Emellertid är kunskapen om varaktigheten The overall aim of this thesis was to investigate quality of life and the meaning of living with peripheral arterial disease (PAD) before and after revascularization in a long-term and methodological perspective. The sample in the first study consisted of 142 patients with PAD who were planned for a revascularization. Quality of life (QoL) assessment with the Nottingham Health Profile (NHP) was ma

Objective. To evaluate results, complications and mortality following percutaneous transluminal renal angioplasty (PTRA) and open surgical revascularisation for renovascular disease. Methods. A retrospective evaluation of 381 renovascular patients (median age 64, range 9-99 years, 152 women) treated at Malmo University Hospital during 1987-1996. Two hundred and sixty-two (69%) of the patients were

A systematic review of radiation therapy trials in several turnout types was performed by The Swedish Council of Technology Assessment in Health Care (SBU). The procedures for evaluation of the scientific literature are described separately (Acta Oncol 2003; 42: 357-365). This synthesis of the literature on radiation therapy for urinary bladder cancer is based on data from 3 meta-analyses and 33 r

A new method was developed for continuous measurement of the middle ear pressure during a 24-h period. The equipment consisted of a piezo-electric pressure device and a digital memory. To allow continuous pressure recordings during normal every-day activities the equipment was made light and portable. The measurement accuracy of the equipment as well as the base-line and temperature stability were

This communication addresses a simple question by means of density functional calculations: Why is iron used as the metal in. iron-sulfur clusters? While there may be several answers to this question, it is shown here that one feature - the well-defined inner-sphere reorganization energy of self-exchange electron transfer - is very much favored in iron-sulfur clusters as opposed to metal substitut

The pH- and the temperature dependence of the rate constant for electron transfer from tyrosine to ruthenium in Ru(II)(bpy)2(4-Me-4'CONH-L-tyrosine etyl ester-2,2'-bpy) 2PF6 was investigated using flash photolysis. At a pH below the tyrosine pKa 10 the rate constant increased monotonically with pH. This increase was consistent with a concerted electron transfer/deprotonation mechanism. Also indica

We report on a theoretical study of the electronic structure of [100]-oriented free-standing III-V semiconductor nanowires with quadratic (square wire) and rectangular (nanobelt) cross-sections based on an atomistic tight-binding approach. It is shown that at the same cross-section aspect ratio, the characteristics of the band structure and state wave functions of the nanowires in the vicinity of
