PEG self-diffusion coefficients of poly(ethylene glycol)s (PEGs) (1080, 8500, and 82 250 g/mol) were measured by PFG-NMR spectroscopy in whey protein solutions and gels in relation to whey protein concentration effects (from 6.49 to 40.45 g/100 g) and whey protein heat denaturation effects (30 min at 70 degrees C). A strong dependency of diffusion on probe size was observed in both whey protein so

Infection with Trypanosoma cruzi causes megasyndromes of the gastrointestinal (GI) tract. We used magnetic resonance imaging (MRI) to monitor alterations in the GI tract of T. cruzi-infected mice, and to assess the role of nitric oxide (NO) in the development of intestinal dilation. Brazil strain-infected C57BL/6 wild-type (WT) mice exhibited dilatation of the intestines by 30 days post-infection.

Two genetically modified potato starches derived from the same mother line (64%, 1% and 23% amylose, respectively) were used to study the bioavailability after various heat treatments. The conditions for the treatments were of minor importance for resistant starch (RS) formation and hydrolysis results, as compared to the proportion of amylose. A high amylose content gave lower hydrolysis index (HI

Moisture and ionic transport under non-saturated condition is an important, but poorly understood transport phenomena particularly for mature systems containing supplementary cementitious materials. This paper investigates the moisture and chloride profiles of 3-year old mortars containing Portland cement (OPC), slag and silica fume (SF) after long-term (30–48 months) wick action exposure in 1.09

The object of this study was to determine the association between tender point pain ratings, tender point counts and distress in people with fibromyalgia and to review the pharmacotherapy of fibromyalgia. Demographic, psychosocial, and health status information was collected from 316 health maintenance organization members with fibromyalgia. A manual tender point exam was conducted. Tender point c

In the present study, neuronal and Schwann cell marker proteins were used to biochemically characterize the spatiotemporal progress of degeneration/regeneration in the silicone chamber model for nerve regeneration. Rat sciatic nerves were transected and the proximal and distal stumps were inserted into a bridging silicone chamber with a 10-mm interstump gap. Using dot immunobinding assays, S-100 p

This paper presents a test of modelling of fungal growth based on the heat produced by Penicillium roqueforti growing on malt extract agar. Thermal power (heat production rate) of P. roqueforti was measured by isothermal calorimetry at 10, 15, 20, 25 and 30°C. The equivalent diameter of similar colonies growing at 20°C were measured by image analysis. Four predictive equations including time lag w

A two-stage procedure for pretreatment of fast-growing willow with steam has been investigated. The first stage was performed at temperatures in the range 180°C to 220°C for times between 6 and 10 minutes while the second stage was performed at 220°C for 10 minutes. The fibrous material was washed between the two stages to remove the pentosans and thus increase the pentose yield. The pretreatment

CONCLUSION: Subjects with self-reported nasal symptoms following consumption of red wine may respond with less nasal blockage to a wine produced with ecological methods than to wine not labelled as ecologically produced. OBJECTIVE: To compare nasal symptoms following intake of three different wines--one that was ecologically produced and two that were traditionally produced. SUBJECTS AND METHODS:

Here we report on the development of a proteomic platform utilizing a piezoelectric flow-through dispensing unit made from silicon microstructures. The use of a novel surface coating, where matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI MS) targets were uniformly precoated with a thin film of matrix/nitrocellulose, made the sample preparation straightforward an

MOS devices based on III-V semiconductors and thin high-k dielectric layers offer possibilities for improved transport properties. Here, we have studied the interface structure and chemical composition of realistic MOS gate stacks, consisting of a W or Pd metal film and a 6- or 12-nm-thick HfO2 layer deposited on InAs, with Hard X-ray Photoemission Spectroscopy. In and As signals from InAs buried

In a study of the reaction e(-)e(+)-> W-W+ with the DELPHI detector, the probabilities of the two W particles occurring in the joint polarisation states transverse-transverse (T T), longitudinal-transverse plus transverse-longitudinal (LT) and longitudinal-longitudinal (LL) have been determined using the final states WW -> lvq (q) over bar (l = e, mu). The two-particle joint polarisation probabili

Sewage ponds with exposed sludge are known to be excellent feeding sites for waders during migration. They still exist in parts of the world but are disappearing in pace with introduction of modern methods which do not involve open exposure of the sludge. Here I report a five-year study from a Swedish plant with open sludge ponds in the 1950s when many similar ones were still active. I counted the

The parameters to extract polysaccharide-enriched fractions (PEF) from mushrooms using MAE (microwave-assisted extraction) were adjusted following a full factorial 3 2 experimental design. The highest yield and total carbohydrate values, using Lentinula edodes as model mushroom, were obtained at 180 °C and 30 min. Several mushroom species were submitted to MAE and their PEF yields ranged between

The aim of this study is to evaluate the soft tissue response of the pure and Au-embedded PPg-PEG. PP-g-PEG2000, PP-g-PEG4000, Au-PP-g-PEG2000, and AuPP-g-PEG4000 were obtained via chlorination of polypropylene and polyethylene glycol in the presence of a base with a "grafting onto" technique. Solvent cast films of these four copolymers with PP as a control group were embedded into five different

The purpose of this investigation was to evaluate the personality questionnaire 30 aspects, which is based on the five-factor model. Our aim was to investigate the properties of the questionnaire through explorative factor analysis and reliability ratings. We also set out to explore the factor structure of the test to decide whether the instrument agreed with the five-factor model or not. The ques

Filmdistributionen befinner sig i en ny digital verklighet. Den snabba tekniska utveckling som har ägt rum de senaste decennierna har inneburit stora utmaningar för såväl filmindustrins affärsmodell som de upphovsrättsliga bestämmelser som reglerar skyddet för filmverk och dess upphovsmän. Ett exempel på en bestämmelse vars tillämpningsområde är oklart till följd av den nya distributionen av digitFilm distribution has found itself in a new digital reality. The swift progress of technology that has taken place during the past decades has posed major challenges for both the film industry's business model and for the copyright laws that regulate the area. An example of a regulation whose scope is unclear as a result of the new distribution of digital copies is the principle of exhaustion.

In today’s connected world, businesses are increasingly going online. Additionally, the online industry is transforming into an international business arena, flourishing with opportunities to grow and expand. However, the internationalisation has raised a number of challenging issues. One of these challenges is foreign exchange. Foreign exchange is needed to sell and buy on markets with different
