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
The vapour-liquid partition of various VOC (Volatile Organic Compounds) in a number of industrial black liquors was investigated. The information can be used to determine the distribution of VOC in different condensate and gas streams in a kraft mill. Batchwise evaporation of weak black liquors was performed on a lab scale. The evaporation was carried out at atmospheric pressure up to over 90% dry
Background The study was designed to evaluate the analgesic effect and possible adverse effects of acupuncture for pelvic and low-back pain during the last trimester of pregnancy. Methods Following individual informed consent, 72 pregnant women reporting pelvic or low-back pain were randomized during pregnancy weeks 24-37 to an acupuncture group (n = 37) or to a control group (n = 35) at three mat
Förmaksflimmer är en vanlig och behandlingskrävande hjärtrytmrubbning. Det kroniska förmaksflimret finner man i befolkningen från 50-årsåldern i alltmer ökande omfattning. Antalet individer i Norge med denna rytmrubbning beräknas vara drygt 40000 och ökar med ytterligare cirka 5000 till år 2010. Mekanismerna bakom initiering och underhåll av förmaksflimmer kartläggs allt bättre. Den paroxysmala foAtrial fibrillation is a common and therapy-requiring cardiac arrhythmia. The chronic form becomes identified in population studies from the age of 50 and increases with age. The number of Norwegian individuals with this arrhythmia is estimated to be slightly in excess of 40,000 and it will increase approximately by another 5,000 until the year 2010. Mechanisms responsible for initiation and maint
The gerronemins A-F (1-6) were isolated as the cytotoxic components of an extract of a Gerronema species detected in a screening for new cytotoxic metabolites from basidiomycetes. Their structures were elucidated by spectroscopic techniques, and they are composed of a C-12-C-16 alkane or alkene substituted at both ends by 2,3-dihydroxyphenyl groups. The gerronemins blocked the inducible expression
The development and transplantation of autologous cells derived from nuclear transfer embryonic stem cell (NT-ESC) lines to treat patients suffering from disease has been termed therapeutic cloning. Human NT is still a developing field, with further research required to improve somatic cell NT and human embryonic stem cell differentiation to deliver safe and effective cell replacement therapies.
