DSC studies of gamma irradiation influence on gelatinisation and amylose-lipid complex transition occurring in wheat starch.

Differential scanning calorimetry studies are presented dealing with the influence of gamma irradiation (carried out in the solid state) on the structure of amylose–lipid complex in wheat starch. Suspensions of the control and the wheat starch irradiated with a 30 kGy gamma rays (characterised by starch-to-water ratio of 1:1 and ca. 1:4) were examined during several courses of heating and cooling

Does supervised exercise after deep venous thrombosis improve recanalization of occluded vein segments? A randomized study.

Objectives The aim of the present study was to evaluate weather early supervised exercise improves recanalization of acute deep vein thrombosis (DVT) and reduces symptoms. Patients and methods From September 2001 to March 2004, of 381 patients, 72 eligible patients were included and with a mean age 54 +/- 14 years, 39 (52%) men with deep vein thrombosis ( DVT) proven with phlebography were randomi

Enteroskopikapseln- sväljbart engångsinstrument för videoundersökning av tunntarmen

Since 1,5 years wireless enteroscopy with the GivenM2A-capsule has been tested clinically. Wireless capsule-enteroscopy (WCE) has already contributed significantly to the understanding of patients with obscure intestinal symptoms. Series of occult bleeders show that WCE detects lesions in 60%, whereas enterography only in 15%, and push-enteroscopy in 25%. Lesions detected are angiodysplasia in 55

Peptidyl diazomethylketones as cysteine protease inhibitors structurally based upon the inhibitory centers of cystatins

Six new putative cysteine protease inhibitors based upon sequences of the N-terminal binding fragments of rat cystatin A, bovine cystatin C and human cystatins D and S were synthesized, inhibitory activities of these compounds against papain and bovine cathepsin B were tested. Additionally, agar well diffusion test of their antibacterial activity against Streptococcus pyogenes was performed.

Consumers choice of organic versus conventional fruit and vegetables - The role of the grocery store

This paper presents findings from two explorative studies. One is a consumer study based on interviews with consumers in real store settings and one is a study based on interviews with fruit and vegetable managers of stores affiliated with a major food retail chain in Sweden. The aim of both studies was to explore the role of the grocery store for the consumers' choice of organic versus convention

Search for bosonic stop decays in R-parity violating supersymmetry in e(+)p collisions at HERA

A search for scalar top quarks in R-parity violating supersymmetry is performed in e(+)p collisions at HERA using the H1 detector. The data, taken at roots = 319 GeV and 301 GeV, correspond to an integrated luminosity of 106 pb(-1). The resonant production of scalar top quarks t in positron quark fusion via an R-parity violating Yukawa coupling lambda' is considered with the subsequent bosonic sto

A mild phenotype of autosomal dominant retinitis pigmentosa is associated with the rhodopsin mutation Pro-267–Leu

By screening blood samples from patients with autosomal dominant retinitis pigmentosa, we found in one of the families a rhodopsin mutation (Pro-267-Leu), which segregates with the disease in two affected and five unaffected family members. Here, we present the results of the clinical evaluation of the family, including full-field electroretinography from the two affected family members. A 25-year

Neuronal integration in an abutting-retinas culture system

PURPOSE: Limited integration is consistently observed between subretinal transplants and host retinas. In the current study, an in vitro model system for studying connections forming between two abutting retinas was developed.METHODS: Neuroretinas were dissected from normal wild-type (WT) mice and green fluorescent protein (GFP) transgenic mice (obtained at postnatal days [P]0, P5, or P60), as wel

Optimal algorithms for complete linkage clustering in d dimensions

It is shown that the complete linkage clustering of n points in R-d, where d greater than or equal to 1 is a constant, can be computed in optimal O(nlogn) time and linear space, under the L-1 and L-infinity-metrics. Furthermore, for every other fixed L-t-metric, it is shown that it can be approximated within an arbitrarily small constant factor in O(nlogn) time and linear space.

Polynuclear aromatic hydrocarbons in fly ash from pressurized fluidized bed gasification of fuel blends. A discussion of the contribution of textile to PAHs

The identification and quantification of 20 different polynuclear aromatic hydrocarbons (PAHs) in the fly ash from a pressurized fluidized bed (PFB) air gasification system based:on hot gas filtering were determined by GC-MS analysis. A comparison was made on the basis of the results from two different sets of experiments with varied gasifier feedstock. The first set included four experiments with

Metal organic chemical vapor deposition of ultrathin ZrO2 films on Si(100) and Si(111) studied by electron spectroscopy

The growth of ultrathin ZrO2 films on Si(100)-(2 x 1) and Si(111)-(7 x 7) has been studied with core level photoelectron spectroscopy and X-ray absorption spectroscopy. The films were deposited sequentially by chemical vapor deposition in ultra-high vacuum using zirconium tetra-tert-butoxide as precursor. Deposition of a > 50 angstrom thick film leads in both cases to tetragonal ZrO2 (t-ZrO2), whe

Radial surface segregation in free heterogeneous argon/krypton clusters

Free clusters produced by a co-expansion of argon and krypton have been studied by means of core level photoelectron spectroscopy. In this study we have determined: (i) the produced clusters are heterogeneous; (ii) the radial distribution of the two atomic species in the cluster differs. The proposed structure model places the majority of the krypton atoms in the bulk, leaving the argon atoms to b

Localization via ultra-wideband radios: A look at positioning aspects of future sensor networks

UWB technology provides an excellent means for wireless positioning due to its high resolution capability in the time domain. Its ability to resolve multipath components makes it possible to obtain accurate location estimates without the need for complex estimation algorithms. In this article, theoretical limits for TOA estimation and TOA-based location estimation for UWB systems have been conside
