The Crystal Structure of Sb0.92V0.92O4, Determined by Neutron and Dual Wavelength X-ray Powder Diffraction

A phase of approximate composition SbVO4 has been reported in the literature as a key component in new catalysts for the ammoxidation of propane to acrylonitrile. Sb0.92V0.92O4 was prepared by heating equimolar amounts of Sb2O3 and V2O5 in air at 1073 K for 2 hr. The chemical composition was determined by thermogravimetry and energy dispersive X-ray microanalysis. The crystal structure at 293 K wa

Role of electronic localization and charge-vibrational coupling in resonant photoelectron spectra of polymers: Application to poly(para-phenylenevinylene)

A combination of x-ray absorption and resonant photoemission (RPE) spectroscopy has been used to study the electronic structure of the one-dimensional conjugated polymer poly (para-phenylenevinylene) in nonordered (as prepared) thin films. The dispersion of RPE features for the decay to localized and delocalized bands are qualitatively different. A theory for band dispersion of RPE in polymers is

Protective role of sympathetic nerve activity to exercising skeletal muscle in the regulation of capillary pressure and fluid filtration

This study describes the integrated sympathetic/metabolic control of capillary pressure (Pc) and filtration in cat skeletal muscle as studied during graded exercise and superimposed graded (2, 6 and 16 Hz) vasoconstrictor nerve excitation. The applied technique permitted simultaneous analysis of the underlying changes of resistance in the whole vascular bed (RT) and in its large-bore arterial resi

Aviation on the ground: Safety culture in a ground handling company

Ground handling work performance is an important part of the civil aviation flight cycle. Well-functioning safety management for minimizing the risk for accidents is vital and dependent on the safety culture. This article reports on a safety culture assessment of a ground handling company using a multiplex approach method. The study is included in the establishment of reference data concerning saf

Genetic diversity in hepatitis C virus in Egypt and possible association with hepatocellular carcinoma

Egypt has one of the world's highest prevalences of hepatitis C virus (HCV) infection, with a majority of genotype 4 infections. To explore the genetic diversity of HCV in Egypt, sera from 131 Egyptians [56 from community studies, 37 chronic hepatitis patients, 28 hepatocellular carcinoma (HCC) patients and 10 patients with non-Hodgkin's lymphoma] were genotyped by restriction fragment-length poly

Putsade fasader : teori och praktiska erfarenheter

SAMMANFATTNING Rapporten är en översiktlig behandling av praktiska frågeställningar och problem i samband med putsade fasader. Olika fasadbehandlingar beskrivs med avseende på ingående material, egenskaper och användningsområden. I huvudsak behandlas oorganiska tjockputser, oorganiska och organiska ytskikt samt impregneringar. De vanligaste tekniska problemområdena i samband med putser och ytskikt

Osteoporosis, metabolic aberrations, and increased risk for vertebral fractures after partial gastrectomy

A case-control study compared 129 men with earlier partial gastrectomy (operation during the period 1952-1961) with 216 men from a community-based population study. All were born 1910-1915 and the mean age was 72 years. Men with a previous partial gastrectomy had vertebral fractures in 19% compared with 4% (P < 0.01) in the control population. Bone mineral density (BMD) in the right calcaneus meas

Attachment och förlåtelse : attachmentmönsters betydelse för individens tankar, känslor och beteenden inför förövare

Popular Abstract in Swedish Syftet med avhandlingen var att studera eventuella skillnader vad gäller förlåtelse beroende av attachmentmönster. Deltagare i studien (N = 359) var gymnasieelever från Malmö. De instrument som användes var Brennan, Clark and Shaver's Experiences in Close Relationships (ECR) och Enright Forgiveness Inventory (EFI). Resultatet visade att ECR:s avoidance dimension var negThe purpose of this dissertation was to study potential differences in forgiveness depending on attachment-styles. The sample (N = 359) consisted of upper secondary school students from Sweden. The instruments that were used after translation and standardization were: Brennan, Clark and Shaver's Experiences in Close Relationships (ECR) and Enright Forgiveness Inventory (EFI). The results showed th

Vardagslivets resor i den stora staden

Starting from the assumption that travelling has negative consequences for the ecological environment, this study deals with travel behaviour in Malmö. The study focuses on how households with different demographic and socio-economic characteristics and transport needs, confronted with different restrictions and possibilities in the surrounding structures, choose to travel in their everyday life.

Condensation of 1-cyanomethyl-2,3,3-trimethyl-3H-indolium perchlorate with ortho-hydroxy-substituted aromatic aldehydes afforded 1-cyanomethylindoline spiropyrans. The latter underwent rearrangement to bridged 1,3-benzoxazepino[3,2-a]indoles on treatment with a base. The mechanism of the rearrangement includes generation of a carbanion stabilized by a cyano Group.

Semiconductor nanowires for novel one-dimensional devices

Low-dimensional semiconductors offer interesting physical phenomena but also the possibility to realize novel types of devices based on, for instance, ID structures. By using traditional top-down fabrication methods the performance of devices is often limited by the quality of the processed device structures. In many cases damage makes ultra-small devices unusable. In this work we present a recent

Lipopolysaccharide-binding protein increases toll-like receptor 4-dependent activation by nontypeable Haemophilus influenzae

Nontypeable Haemophilus influenzae (NTHi) is a common cause of respiratory tract infections. This study investigated the ability of NTHi to bind lipopolysaccharide-binding protein (LBP) derived from respiratory epithelial cells and the subsequent stimulation of transfected cells expressing membrane-bound CD14 and toll-like receptor 2 (TLR2) or TLR4. In the absence of LBP, NTHi at high concentratio
