2-Hydroxyethyl methacrylate-L-lactate (HEMA-LLA) and HEMA-L-lactate-dextran (HEMA-LLA-D) were synthesized. H-1-NMR confirmed the formation of these oligomers and macromers. Cryogels with different pore structures were prepared using different amounts of HEMA, HEMA-LLA and HEMA-LLA-D by a cryogelation technique. SEM micrographs exhibited pore morphologies. Cryogels were highly porous with interconn

SU-8 is an epoxy-based photosensitive resist, which is currently used for a large variety of MEMS and lab-on-a-chip applications. Here, we demonstrate a one-step process to functionalise SU-8 with DNA probes. The immobilisation procedure relies on direct coupling of DNA to SU-8 and resulted in surfaces with functional capture probe densities of approximately 10 fmol/mm2 as determined by hybridisat

There is no causal treatment for osteoarthritis. Instead treatment is aimed at decreasing pain and improving function. The base of osteoarthritis treatment is education and exercise. Exercise, both aerobic exercise and muscular strength training, have positive effects on pain and function. The minimum recommendations of exercise are equivalent to the recommendations of physical activity to obtain

Examination of the methylene chloride soluble portion of the acetone extract of the seeds of Turreanthus africanus yielded two labdane diterpenoids 12,15-epoxylabda-8(17),12,14-trien-16-al (1) and 16-acetoxy-12(R),15-epoxy-15β-hydroxylabda-8(17),13(16)-diene (2) and a limonoid, 17-epi 12-dehydroxyheudebolin (3). Structures elucidation was based on the analysis of spectroscopic data.

The purpose of this investigation was to test calorimetry as a means of quantifying cell damage occurring at various stages of mild blanching treatments. Calorimetric measurements were carried out on cores taken from carrot slices blanched at 100 degreesC for 5-45 s. The calorimetric data were corrected for the influence of wounding stress due to slicing and coring. The validity of calorimetry to

Diurnal and nocturnal hawkmoths (Sphingidae, Lepidoptera) have three spectral types of receptor sensitive to ultraviolet, blue and green light. As avid flower visitors and pollinators, they use olfactory and visual cues to find and recognise flowers. Moths of the diurnal species Macroglossum stellatarum and the nocturnal species Deilephila elpenor, Hyles lineata and Hyles gallii use and learn the

I denna rapport redovisas teoretiska beräkningar av energibehov till uppvärmning, tappvarmvatten och hushållselektricitet, energitransporter genom småhusens grunder och energiflöden genom köldbryggor. Beräkningarna omfattar 26 småhus på Bo 92 i Örebro med olika typer av grundläggning, värmeisolering, fönster, värme- och ventilationssystem. Beräkningarna har utförts med datorprogrammen ENORM, CRAWL

In this work a one-dimensional model for the mass and heat transport in the thickness direction of paper has been developed. Solid-based coordinates were applied to simplify incorporation of shrinkage. Liquid diffusion, gas convection and vapour and air diffusion were incorporated as mass transport mechansims. In the heat balance the convective heat transport and heat conduction were included. Spe

Nicotinamide adenine dinucleotide-reduced form (NADH):quinone oxidoreductase (respiratory Complex I), F420H2 oxidoreductase and complex, membrane-bound NiFe-hydrogenase contain protein subunits homologous to a certain type of bona fide antiporters. In Complex I, these polypeptides (NuoL/ND5, NuoM/ND4, NuoN/ND2) are most likely core components of the proton pumping mechanism, and it is thus importa

The authors examined Swedish judges', lay judges', and police officers' beliefs about factors that may complicate or facilitate children's reports of sexual abuse. Participants (N = 562) rated potential complicating and facilitating factors and freely reported which criteria they considered important when assessing the reliability of child witnesses. The groups had similar opinions regarding which
