Short-chain fatty acid content in the hindgut of rats fed various composite foods and commercial dietary fibre fractions from similar sources

The fermentability of indigestible carbohydrates and content of short-chain fatty acids along the hindgut of rats were investigated using plant materials of importance in the Swedish diet (instant potato powder, apples and oat flakes). Results with the composite food products were compared with commercial fibre fractions obtained from similar sources, ie potato fibre, apple pectin and beta-glucan-

Spacer and anchor effects on the electronic coupling in ruthenium-bis-terpyridine dye-sensitized TiO2 nanocrystals studied by DFT

Structural and electronic properties of TiO2 nanoparticles sensitized with a set of RuII(tpy)(2) based dyes have been investigated using density functional theory (DFT) calculations combined with time-dependent (TD) DFT calculations. The effects of carboxylic and phosphonic acid anchor groups, as well as a phenylene spacer group, on the optical properties of the dyes and the electronic interaction

Undervisa mot våld. Attityder, läromedel, arbetssätt

Syftena med det i projektet beskrivna inlärnings- experimentet var att studera barns attityder till våld och att med ett attitydtest undersöka effekterna av undervisning mot våld. Samtidigt jämfördes individuellt arbete och grupparbete samt användningen av tre slag av läromedel: texter, bilder och muntliga uppgifter. Både process- och produktvariabler undersöktes. Deltagare var elever i åldrarna 1The main aim of this study has been to influence the attitudes of students, Grades 4-6, in order that they will become opposed to the use of violence. The entire project was conducted during a full academic 20-credit term, as part of inter- mediate level teachers' training. The purpose of this learning experiment was threefold: 1. To study children's attitudes towards violence. 2. To study the eff

Backcross and partial advanced intercross analysis of nonobese diabetic gene-mediated effects on collagen-induced arthritis reveals an interactive effect by two major loci.

Genetic segregation analysis between NOD and C57BL strains have been used to identify loci associated with autoimmune disease. Only two loci (Cia2 and Cia9) had earlier been found to control development of arthritis, whereas none of the previously identified diabetes loci was of significance for arthritis. We have now made a high-powered analysis of a backcross of NOD genes on to the B10.Q strain

Performance modeling and control of web servers

This thesis deals with the task of modeling a web server and designing a mechanism that can prevent the web server from being overloaded. Four papers are presented. The first paper gives an M/G/1/K processor sharing model of a single web server. The model is validated against measurements ands imulations on the commonly usedw eb server Apache. A description is given on how to calculate the necessar

Effects of Trichloroethylene inhalation on acid phosphatase in rodent brain

Rats, mice and gerbils were continuously exposed to 150 ppm trichloroethylene (TCE) for 30 days. In all three species, there was a marked increase in liver weight. In mice the weight increased more (86%) than in rats and gerbils (20%). After exposure the activity of acid phosphatase, a lysosomal marker enzyme, was tested in different brain areas, using a system which had a limit of detection of ±

Trapping of microparticles in the near field of an ultrasonic transducer

We are investigating means of handling microparticles in microfluidic systems, in particular localized acoustic trapping of microparticles in a flow-through device. Standing ultrasonic waves were generated across a microfluidic channel by ultrasonic microtransducers integrated in one of the channel walls. Particles in a fluid passing a transducer were drawn to pressure minima in the acoustic field

Masses, lifetimes and production rates of Xi(-) and Xi(+) at LEP 1

Measurements of the Xi(-) and (Xi) over bar (+) masses, mass differences, lifetimes and lifetime differences are presented. The (Xi) over bar (+) sample used is much larger than those used previously for such measurements. In addition, the S production rates in Z -> b (b) over bar and Z -> q (q) over bar events are compared and the position xi* of the maximum of the distribution in Z -> q (q) over

Defect-Aware SOC Test Scheduling

In this paper we address the test scheduling problem for system-on-chip designs. Different from previous approaches where it is assumed that all tests will be performed until completion, we consider the cases where the test process will be terminated as soon as a defect is detected. This is common practice in production test of chips. The proposed technique takes into account the probability of de

Vitamin D deficiency and ovariectomy reduced the strength of the femoral neck in rats

Vitamin D (vit D) deficiency is common in the elderly, and the aim of this study was to investigate whether vit D deprivation in ovariectomized (ovx) and normal rats would reduce fracture strength. Forty mature female Wistar rats were randomized into four groups: two were ovariectomized (ovx) and two were sham-operated (sham). One ovx and one sham group were fed a vit D-deficient diet (Ovx-D and S

Back pain, disability, and radiographic vertebral fracture in European women: a prospective study

Vertebral fractures are associated with back pain and disability. There are, however, few prospective data looking at back pain and disability following identification of radiographic vertebral fracture. The aim of this analysis was to determine the impact of radiographically identified vertebral fracture on the subsequent occurrence of back pain and disability. Women aged 50 years and over were r

Long-term changes in dietary and food intake behaviour in the Diabetes Prevention Program Outcomes Study

Aims To compare change in dietary intake, with an emphasis on food groups and food intake behaviour, over time across treatment arms in a diabetes prevention trial and to assess the differences in dietary intake among demographic groups within treatment arms. Methods Data are from the Diabetes Prevention Program and Diabetes Prevention Program Outcomes Study. Participants were randomized to a life
