Repeated exposures to both microbial and innocuous Ags in vivo have been reported to both eliminate and tolerize T cells after their initial activation and expansion. The remaining tolerant T cells have been shown to suppress the response of naive T cells in vitro. This feature is reminiscent of natural CD4+CD25+ regulatory T cells. However, it is not known whether the regulatory function of in vi

This dissertation addresses the question of what the function of morphological case is in Icelandic. The working hypotheses of this book is that morphological case is a multifunctional category. Firstly, new verbs in Icelandic were collected and examined to cast light on the productivity of the morphological cases, revealing that not only are the nominative and accusative productive in Icelandic b

Background: Flat and depressed colorectal tumours are common in Japan but are very rare or non-existent in Western countries. Aims: To study the occurrence of flat colorectal tumours in a southern Swedish population. Methods: In this prospective study, 371 consecutive European patients were examined by high resolution video colonoscopy combined with chromoendoscopy. The nature of the lesions was

Popular Abstract in Swedish Fraktal teori applicerad på regn.Fractal theory involving scaling properties has been applied in a wide range of research areas, particularly within natural sciences. In the present thesis, fractal theory has been applied to the rainfall process. The main questions to be answered were: (1) is rainfall characterized by scaling and fractal properties, and, if so, (2) how can these properties be modeled and used in applied hydrology

The max-bisection problem is to find a partition of the vertices of a graph into two equal size subsets that maximizes the number of edges with endpoints in both subsets. We obtain new improved approximation ratios for the max-bisection problem on the low degree k-regular graphs for 3 less than or equal to k less than or equal to 8, by deriving some improved transformations from a maximum cut into

High-speed laser diagnostics was utilized for singlecycle resolved studies of the formaldehyde distribution in the combustion chamber of an HCCI engine. A multi- YAG laser system consisting of four individual Qswitched, flash lamp-pumped Nd:YAG lasers has previously been developed in order to obtain laser pulses at 355 nm suitable for performing LIF measurements of the formaldehyde molecule. Burst

Three experiments were conducted to investigate the impact of affect on moral judgment. Participants read stories describing morally questionable actions and made judgments of wrongness. Judgments were affected by morally irrelevant disgust, and the effect was moderated by individual differences in disgust sensitivity and preferred processing mode. More specifically, the effect was stronger for pa

One of the main problems in using parabolic concentrators with standard photovoltaics (PV) cells is the highly non-uniform illumination of the cells. The non-uniform irradiation causes high resistive losses in the standard cells due to their relatively high series resistance. This results in a considerably lowered efficiency. To solve the problem, we introduce three different structured reflectors

Systemic sclerosis, scleroderma (SSc) is a disabling condition that shortens life expectancy. Disease heterogeneity and difficulties separating SSc from SSc-like conditions make classification an important issue. Limited cutaneous and diffuse cutaneous SSc, with different severity and survival, have been recognized for several years as distinct subsets. Some authors have suggested an intermediate

The carabid beetle Harpalus rufipes has been examined with respect to food preference and food quality. Three different experiments were performed to clarify the role of weedy seeds and insects as food for H. rufipes: 1) adult's food preference, 2) fecundity dependent on diet, and 3) larval development dependent on diet. No direct relation between food preference and food value was found. The seed

OBJECTIVE—Insulin detemir is a soluble long-acting basal insulin analog designed to overcome the limitations of conventional basal insulin formulations. Accordingly, insulin detemir has been compared with NPH insulin with respect to glycemic control (HbA1c, prebreakfast glucose levels and variability, and hypoglycemia) and timing of administration. RESEARCH DESIGN AND METHODS—People with type 1 d

The effect of multivariate adjustment including folate on the strong protective effect of fiber in foods on colorectal cancer risk in the European Prospective Investigation into Cancer and Nutrition was investigated in 1,721 cases identified in the latest follow-up. The inclusion of an additional 656 cases confirmed our previously published results, with a strong and significant reduction in color

The importance of risk characteristics of human capital for the design of tax and education policy is explored. Wages are uncertain and education, while increasing the expected wage, may increase or decrease wage variance. The government has strong reasons to encourage human capital formation in the latter case, partly due to the insurance effect of human capital, and partly due to the way the ind
