Immigrant language groups in Religious Organisations

During the process of migration, many immigrants undergo a number of changes in their relationships to their religious organisations. One factor that has emerged as especially important in immigrants’ congregational affiliation is the availability of language groups in immigrants’ mother tongues. This article examines how these groups are formed and the roles they play in the lives of their member

Heterocyclic amines in poultry products: a literature review.

Health risks associated with heterocyclic amines in cooked foods have been discussed and analysed since the presence of these food mutagens was first detected. Intake, metabolism, carcinogenicity and epidemiology are important parameters in the risk assessment of heterocyclic amines. It is very difficult to determine the human intake of heterocyclic amines, as the content in cooked meat is highly

Hyperfine structure and radiative lifetimes in the 3s2n p2P3/2 sequence of Al-27 using time resolved laser spectroscopy

Using time-resolved laser spectroscopy we have determined the hyperfine structure in the 3s2n p2P3/2 sequence of27Al (I=5/2). The magnetic-dipole interaction constants were found to scale withn*-2.85 (n* is the effective principal quantum number) in the investigated regionn=6–12. Significant quadrupole interaction constants were obtained forn=6–9. The measured radiative lifetimes forn=6–12 scale w

Long-term consequences of respiratory syncytial virus acute lower respiratory tract infection in early childhood in Guinea-bissau

AIM: The study aimed to investigate long-term consequences of respiratory syncytial virus (RSV) positive acute lower respiratory tract infection (ALRI) in a low-income country according to severity of the initial infection. DESIGN: The study was a 1:1 matched case-control study of 335 RSV case children and 335 control children. The mean age of RSV ALRI was 0.9 year and at follow-up, 6.8 years. Cas

Palynology of the Lower Eocene deposits of Northwest Jutland, Denmark

Early Eocene spores and pollen assemblages from the uppermost part of the Stolle Klint Clay and the overlying Fur Formation are diverse and well preserved. The terrestrial microflora comprises 42 species of spores and 108 species of pollen and four spores and pollen zones are established i.e. Interpollis velum-Labrapollis globosus, Basopollis atumenscens, Basopollis orthobasalis and Thomsonipollis

Unilateral denervation of the rat urinary bladder and reinnervation: a predominance for ipsilateral changes

Unilateral removal of the pelvic ganglion affected the bladder-half on the denervated side more profoundly than that on the non-denervated side. At an early stage (3-7 days) the former was heavier, had a lower choline acetyltransferase activity, developed less tension to nerve stimulation and, in course of time, became more sensitized to methacholine in vitro than the latter. At a late stage (30-6

High-rate dual-target dc magnetron sputter deposition of electromagnetic MoO3

Mo oxide films with good electrochromic properties were produced by single-target and dual-target reactive d.c. magnetron sputtering. Dual-target deposition was shown capable of yielding optically functional films at a rate ∼ 20 times higher than that for single-target deposition, which is a result of considerable technical interest.

A controlled comparison of myelography, computed tomography, and magnetic resonance imaging in clinically suspected lumbar disc herniation

STUDY DESIGN. A controlled prospective blinded study. OBJECTIVES. To compare the diagnostic power of myelography, computed tomography and magnetic resonance imaging in the diagnosis of low lumbar disc herniation. METHODS. Eighty patients with monoradicular sciatica were examined by myelography, computed tomography, and magnetic resonance imaging, and all underwent subsequent surgery. The images we

Ultrafast singlet energy transfer competes with intersystem crossing in a multi-center transition metal polypyridine complex

Transition metal polypyridine complexes are finding widespread applications within many areas of chemistry. For their light-induced processes, the generally accepted picture is that all function emanates from triplet states because the singlet states initially prepared by light absorption are depopulated via intersystem crossing on the 100-fs time scale, before they are significantly involved in c

Stochastic model for the investigation of the influence of turbulent mixing on engine knock

A stochastic model based on a probability density function (PDF) was developed for the investigation of different conditions that determine knock in spark ignition (SI) engine, with focus on the turbulent mixing. The model used is based on a two-zone approach, where the burned and unburned gases are described as stochastic reactors. By using a stochastic ensemble to represent the PDF of the scalar

Abnormal mechanical properties of the aorta in Marfan's syndrome

OBJECTIVES: Aortic dilatation, dissection and rupture are among the major causes of death in subjects with Marfan's syndrome. The aim of the study was to investigate the mechanical properties or compliance of the aorta in these subjects and compare them with a healthy age- and sex-matched reference population. MATERIALS AND METHODS: An ultrasound phase-locked echo-tracking system was used to deter

Tänkande bakom val och användning av livsmedel : Faktorer som medverkar till eller utgör hinder för förändring av matvanor i hälsofrämjande riktning

Popular AbstractAvhandlingsarbetet fokuserar tänkande och handlande i förhållande till livsmedel som pedagogiska förutsättningar för förståelse av kostbudskap och näringsrekommendationer.Studiens syfte var att undersöka och beskriva hur tidigare erfarenheter framträder i människors tänkande och handlande i förhållande till deras val och användning av fettrika resp. kostfiberrika livsmedel för att For educational purposes, research has been proposed on the circumstances and facts which govern eating habits and the intake of nutrients. By focusing on the perspective of the individual, this study explores and describes how previous experiences influence people's thinking and acting in relation to their present eating habits to elucidate factors that contribute to, or hinder, changes for the p

Influence of shear rate on the flux during ultrafiltration of colloidal substances

The shear rate at the surface of a membrane has a distinct influence on the membrane flux in systems containing colloidal substances. If the shear rate is decreased, flux decreases since the thickness of the boundary layer of retained solutes at the membrane surface then increases. When low molecular solutes are used, flux increases again when the shear rate is increased. However, if large solutes
