Qualitative and quantitative changes were observed in lipids, poly-β-hydroxybutyrate (PHB), and a cell wall peptidoglycan consitutent in a marine bacterial isolate during starvation for 24 h in an energy and nutrient-free medium. While the amount and composition of the membrane fatty acids fluctuated within the first hours of starvation, the total amount of fatty acids decreased during the starvat

Fabrication of silicon carbide fibres reinforced silicon carbide composite (SiC/SiC) by chemical vapour infiltration (CVI) process was investigated in this research with the help of both simulation and experimental set-up. CVI of silicon carbide preform was carried out through the pyrolysis of methyltrichlorosilane (MTS) over a broad temperature range at atmospheric pressure. The overall aim was t

Purpose: The purpose of this study was to investigate what treatment methods physiotherapists in Sweden use for infants 0–24 months hospitalised with acute breathing difficulties due to lower respiratory tract infections. Material and methods: We constructed an anonymous digital survey for paediatric physiotherapists in Sweden. It was distributed by e-mail and was posted on professional websites.

This article describes field monitoring and supplementary simulations of an existing daylighting and electric lighting integrated design for a furniture store. First in its type, the store includes several areas of the showroom provided with abundant daylighting. For the monitoring, the areas of the living rooms and the home decoration exhibitions were selected. They include wide glazed areas, day

We address the interplay of electron-electron (e-e) and electron-phonon (e-ph) interactions in the Hubbard- Holstein model, using a two-component density functional theory. Exchange-correlation potentials constructed via dynamical mean field theory for a D = ∞ Bethe lattice and analytically for an isolated site give a new perspective on e-ph screening of the e-e interactions and its effect on the

Context: Breathlessness is associated with depression, but its relationship to anxiety or impaired function is less clear. Objectives: This study evaluated associations between chronic breathlessness and anxiety, depression, and functional status in the general population. Methods: This cross-sectional study of consenting adults (18 years and older) used an online survey. Quota sampling (n = 3000)

Expression of the epidermal growth factor (EGF) receptors HER1 and HER2 has been implicated in tumour growth and poor survival, whereas expression of HER3 and HER4 has been associated with improved survival of bladder cancer patients. The balance between the expression of the EGF family members may therefore have a role to play in determining the final outcome in cancer cells. To check this, we ex

Fibroblasts synthesize a variety of proteoglycans among which is a family of structurally related small proteoglycans, i.e. PG-S1 (biglycan) and PG-S2 (decorin). Fibromodulin, which is present in some tissues as a keratan sulfate proteoglycan, also belongs to this family. We have used primary fibroblasts from fetal skin and bovine sclera in culture to study the metabolism of proteoglycans. In part

Permafrost degradation has the potential to change the Arctic tundra landscape. We observed rapid local thawing of ice-rich permafrost resulting in thaw pond formation, which was triggered by removal of the shrub cover in a field experiment. This study aimed to examine the rate of permafrost thaw and the initial vegetation succession after the permafrost collapse. Methods In the experiment, we mea

S100 protein, normally not found in serum, is increased after cerebral injury and is also released during ECC. Patients with neurological complications following cardiac surgery have residual concentrations due to a prolonged release from cellular injury. The aim of the present study was to characterize the S100 release that occurs after CABG in a "normal" population without clinical brain dysfunc

Normalisation of measured energy use in buildings is important in order to verify their performance in user phase. Two methods for normalisation have been presented in Sweden, static and dynamic normalisation. The static normalisation considers deviating hot water use, indoor temperature, internal loads and external climate. The dynamic normalisation is based on repeated simulation, meaning that t

Metabolomics is now widely used to characterize metabolic phenotypes associated with lifestyle risk factors such as obesity. The objective of the present study was to explore the associations of body mass index (BMI) with 145 metabolites measured in blood samples in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Metabolites were measured in blood from 392 men from t

Changes in mitochondrial DNA (mtDNA) content is a useful clinical biomarker for various diseases, however results are controversial as several analytical factors can affect measurement of mtDNA. MtDNA is often quantified by taking ratio between a target mitochondrial gene and a reference nuclear gene (mtDNA/nDNA) using quantitative real time PCR often on two separate experiments. It measures relat

Quantitative characterization of a high-power glow-mode gliding arc (GM-GA) discharge operated in open air is performed using a current-voltage lumped model that is built from the perspective of energy balance and electron conservation. The GM-GA discharge is powered by a 35 kHz alternating current power supply. Instantaneous images of the discharge volume are recorded using a high-speed camera at
