Asymmetric self-assembly of oppositely charged composite microgels and gold nanoparticles

The electrostatically driven self-assembly of oppositely charged gold nanoparticles (Au NPs) and polystyrene/poly(N-isopropylacrylamide) (PS/PNIPAm) core-shell microgels (CSMs) has been investigated. The co-assembly was accomplished by addition of smaller Au NPs to CSMs in dilute conditions up to a number ratio of about 1 : 1, when the suspension is destabilized. A combination of different techniq

Effect of Temperature Stratification on the Auto-Ignition of Lean Ethanol/Air Mixture in HCCI Engine

It has been known from multi-zone simulations that HCCI combustion can be significantly affected by temperature stratification of the in-cylinder gas. With the same combustion timing (i.e., crank angles at 50% heat release, denoted as CA50), large temperature stratification tends to prolong the combustion duration and lower down the in-cylinder pressure-rise-rate. With low pressure-rise-rate HCCI

New susceptibility locus for coronary artery disease on chromosome 3q22.3

We present a three-stage analysis of genome-wide SNP data in 1,222 German individuals with myocardial infarction and 1,298 controls, in silico replication in three additional genome-wide datasets of coronary artery disease (CAD) and subsequent replication in similar to 25,000 subjects. We identified one new CAD risk locus on 3q22.3 in MRAS (P = 7.44 x 10(-13); OR = 1.15, 95% CI = 1.11-1.19), and s

Preparation and characterization of ellipsoidal-shaped thermosensitive microgel colloids with tailored aspect ratios

Prolate model colloids with defined properties can be obtained by the stretching of spherical polymeric particles, which is well-known for polystyrene and poly(methyl methacrylate) latices. The present study aims to extend this approach to functional core-shell particles in order to achieve a new class of anisotropic colloidal materials where both the aspect ratio and the effective volume fraction

Consensus Pathways Implicated in Prognosis of Colorectal Cancer Identified Through Systematic Enrichment Analysis of Gene Expression Profiling Studies

Background: A large number of gene expression profiling (GEP) studies on prognosis of colorectal cancer (CRC) has been performed, but no reliable gene signature for prediction of CRC prognosis has been found. Bioinformatic enrichment tools are a powerful approach to identify biological processes in high-throughput data analysis. Principal Findings: We have for the first time collected the results

Cross-reactions between engineered xylose and galactose pathways in recombinant Saccharomyces cerevisiae

BACKGROUND: Overexpression of the PGM2 gene encoding phosphoglucomutase (Pgm2p) has been shown to improve galactose utilization both under aerobic and under anaerobic conditions. Similarly, xylose utilization has been improved by overexpression of genes encoding xylulokinase (XK), enzymes from the non-oxidative pentose phosphate pathway (non-ox PPP) and deletion of the endogenous aldose reductase

Forskning om diakoni - en litteraturöversikt

En inventering och presentation av fr.a. svensk forskning om diakoni och kyrkors sociala verksamheter. Först redovisas historisk forskning om fattigvård och diakoni. Därefter samhälls- och flervetenskaplig forskning, samt forskning om diakonatet och systematisk-teologisk forsknning

Cardiovascular disease and adrenergic dysfunction in mild primary hyperparathyroidism

Popular Abstract in Swedish Primär hyperparathyroidism (PHPT) är en sjukdom som beror på abnormt ökad produktion av parathormon (PTH) i en eller flera av de vanligen fyra bisköldkörtlarna. PTH har som uppgift är att reglera nivån av kalcium i blodet (i dagligt tal ofta kallad ”blodkalken”) inom snäva gränser. Den förhöjda halten av PTH och den åtföljande stegringen av kalciumnivån i blodet vid PHPPrimary hyperparathyroidism (PHPT) is associated with cardiovascular morbidity and premature death, but the underlying mechanisms are incompletely understood. The aim of this thesis was to investigate cardiovascular parameters and adrenergic function in mild PHPT compared to healthy controls subjects before and after curative parathyroidectomy (PTX). Forty-nine patients with mild PHPT (serum calci

Power Transformer Immune to Geomagnetically Induced Currents

Geomagnetically induced currents (GICs) flow mainly through power lines, earthed transformers and earth itself. The near DC currents may cause half-cycle saturation of transformers, possibly causing relay misoperation, increased reactive power demand and damage to transformers. This paper describes a patented idea to make a transformer immune to GIC using compensation windings in each phase. A com

Stress analysis of highly constrained copper strips with through crack shaped voids using molecular dynamics

A small rectangular strip of fcc Cu, containing a through crack on the nanoscale and subjected to loading under displacement control, is simulated using molecular dynamics (MD). The geometry is highly constrained and chosen to mimic that of a thin strip between two stiff layers. The Lennard-Jones pair potential is used for the inter-atomic forces. The centrally placed crack shaped void is created

To the rhythm of shopping - on synchronisation in urban landscapes of consumption

This article deals with the impact of retail rhythms on urban life and the urban landscape, with a special focus on tendencies toward synchronisation. The article is divided into three sections. First, the history of synchronisations in public space is traced, and it is argued that the retail business has become an increasingly important actor in the production of urban temporal landscapes. Second

Dilepton mass spectra in p plus p collisions at root s=200 GeV

PHENIX has measured the electron-positron pair mass spectrum from 0 to 8 GeV/c(2) in p + p collisions at root s = 200 GeV. The contributions from light meson decays to e(+)e(-) pairs have been determined based on measurements of hadron production cross sections by PHENIX. Within the systematic uncertainty of similar to 20% they account for all e(+)e(-) pairs in the mass region below similar to 1 G

Regional Management Units for Marine Turtles: A Novel Framework for Prioritizing Conservation and Research across Multiple Scales

Background: Resolving threats to widely distributed marine megafauna requires definition of the geographic distributions of both the threats as well as the population unit(s) of interest. In turn, because individual threats can operate on varying spatial scales, their impacts can affect different segments of a population of the same species. Therefore, integration of multiple tools and techniques

Validity and reliability of the Cold Discomfort Scale: a subjective judgement scale for the assessment of patient thermal state in a cold environment

Complementary measures for the assessment of patient thermoregulatory state, such as subjective judgement scales, might be of considerable importance in field rescue scenarios where objective measures such as body core temperature, skin temperature, and oxygen consumption are difficult to obtain. The objective of this study was to evaluate, in healthy subjects, the reliability of the Cold Discomfo
