CdTe semiconductor nanocrystals were synthesized with three different stabilizers: Mercaptoacetic Acid (MM), Mercaptopropionic Acid (MPA) and 2-Mercaptoethanol (ME) at pH approximate to 11.2 by wet chemical route using potassium tellurite and cadmium chloride as starting materials. The effect of capping agent on the preparation of these samples was evaluated using UV-Visible absorption and photolu

Objectives: To investigate whether low self-rated health (SRH) is associated with increased mortality in individuals with diabetes. Design: Population-based prospective cohort study. Setting: Enrolment took place between 1992 and 2000 in four centres (Bilthoven, Heidelberg, Potsdam, Umea) in a subcohort nested in the European Prospective Investigation into Cancer and Nutrition. Participants: 3257

The alleged efficacy of pharmaceutical industry self-regulation has been used to repudiate increased government oversight over promotional activity. European politicians and industry have cited Sweden as an excellent example of self-regulation based on an ethical code. This paper considers antidepressant advertising in Sweden to uncover the strengths and weaknesses of self-regulation.

Tamoxifen is associated with a reduced risk of coronary heart disease (CHD). However, there are few reports on long-term effects. Using data from a large Swedish randomized trial of 5 and 2 years of adjuvant tamoxifen in women with early breast cancer, we here present results on morbidity and mortality from cardiac diseases during treatment and long-term after treatment. A total of 4,150 patients

An active polyphase filter capable of high frequency quadrature signal generation has been analyzed. The resistors of the classical passive polyphase filter have been replaced by transconductors, CMOS inverters [1,2]. A three-stage 0.13 um CMOS active polyphase filter has been designed. Simulations with a differential input signal show a quadrature error less than 1◦ for the full stable input volt

The geometric and electronic structure of condensed phase organic conducting polymer PEDOT:PSS blends has been investigated by periodic density functional theory (DFT) calculations with a generalized-gradient approximation (GGA) functional, and a plane wave basis set. The influence of the degree of doping of the PEDOT polymer on structural and optical parameters such as the reflectivity, absorbanc

Dalteparin, a low molecular weight heparin (LMWH), is given to pregnant women with thrombotic disorders. Clinical observations together with the documented changes of heparan sulfate proteoglycans in normal and protracted labor fostered the idea that LMWH shortens delivery time. Labor time was retrospectively determined among nulliparous pregnant women treated with dalteparin because of previous v

The bluethroat Luscinia svecica is a particularly interesting species for the study of the mechanisms that control migration because it comprises several recently diverged subspecies that differ in migratory distance and direction. Here we use ringing data to describe the migration strategy and winter distribution of L. s. cyanecula and L. s. namnetum along the eastern Atlantic coast of Iberia and

Popular Abstract in Swedish Fallolyckor hos äldre -en tyst epidemi Fallolyckor hos äldre är idag ett omfattande men underrapporterat hälsoproblem. Cirka 1,600 individer, en huvuddel äldre, avlider årligen i Sverige till följd av ett fall. Detta kan jämföras med 1,400 respektive 2,400 individer som avlider årligen av bröst- och prostatacancer. Strax under 300 individer dör årligen i trafiken i SveIn a ‘greying world’ with aging populations, falls in the elderly are a challenge to the health care system as they are associated with substantial mortality and morbidity. Apart from physical injuries, the consequences of falls are broad, with additional psychological and social consequences. The overall objective of this dissertation was to study falls and related risk factors, predictors, and c

Objective - To examine whether there were any differences in the recovery in performance of personal activities of daily living (P-ADL) in elderly persons in relation to cognitive impairments pre- and post-stroke from discharge to 6 and 12 months in elderly persons. Methods - Forty-five elderly persons after stroke were assessed at discharge from hospital and at 6 and at 12 months after stroke ons

To identify markers of non-response to neoadjuvant chemotherapy (NAC) that could be used in the adjuvant setting. Sixteen pathologists of the European Working Group for Breast Screening Pathology reviewed the core biopsies of breast cancers treated with NAC and recorded the clinico-pathological findings (histological type and grade; estrogen, progesterone receptors, and HER2 status; Ki67; mitotic

Numerous different bioreactor systems are applied for hydrogen production by dark fermentation. Thermophilic fermentations are gaining an increased interest due to the high hydrogen yields associated with them. In order to reach the best thermophilic fermentation system, 2 types of bioreactors, a trickling bed and a fluidized bed system, were constructed and operated under similar conditions. Both

Palsa mires, nutrient poor permafrost peatlands common in subarctic regions, store a significant amount of carbon (C) and it has been hypothesized their net ecosystem C balance (NECB) is sensitive to climate change. Over two years we measured the NECB for Stordalen palsa mire and found it to accumulate 46 g C m(-2) yr(-1). While Stordalen NECB is comparable to nutrient poor peatlands without perma

BACKGROUND: Previous studies have suggested that the use of mesh in groin hernia repair may be associated with an increased risk for male infertility as a result of inflammatory obliteration of structures in the spermatic cord. In a recent study, we could not find an increased incidence of involuntary childlessness. The aim of this study was to evaluate this issue further. METHODS: Men born betwee

Toleranser är de mått som visar hur mycket konstruktionen får avvika från ritning till tillverkning, utsättning och montering och ändå nå de krav som ställts på slutprodukten. Allt byggande då olika komponenter ska monteras ihop kräver noggrannhet och precision. Detta så att de olika byggdelarna passar ihop då de ska monteras på byggarbetsplatsen. Passar inte de olika delarna så blir det korrigeri

Despite the importance of both response probability and response time for testing models of choice there is a dearth of chronometric studies examining systematic asymmetries that occur over time- and space-orders in the method of paired comparisons. In this study, systematic asymmetries in discriminating the magnitude of paired visual stimuli are examined by way of log-odds ratios of binary respon

Spectra of coherent bremsstrahlung from the diamond crystal in the laboratory MAX-lab on the accelerator MAX-I are measured at the energy of the electronic beam 144 MeV. First in the laboratory MAX-lab a source of the polarized photon radiation was created. Photon spectra were compared with theoretical calculations, that allow to estimate a magnitude of photon polarization, which is sufficient, fo

Optimization of sensory processing during development can be studied by using photoreceptors of hemimetabolous insects (with incomplete metamorphosis) as a research model. We have addressed this topic in the stick insect Carausius morosus, where retinal growth after hatching is accompanied by a diurnal-to-nocturnal shift in behavior, by recording from photoreceptors of first instar nymphs and adul
