A quadrature voltage controlled oscillator (QVCO) topology exhibiting low power consumption and high phase noise performance at low supply voltages is presented. The QVCO buffer includes varactors to maximize the output voltage and minimize the current consumption. Microstrip theory and the principle of conservation of energy have been used to evaluate the distributed capacitances of symmetrical i

Adiponectin is a hormone secreted from adipose tissue, and serum levels are decreased with obesity and insulin resistance. Because prolactin (PRL) and growth hormone (GH) can affect insulin sensitivity, we investigated the effects of these hormones on the regulation of adiponectin in human adipose tissue in vitro and in rodents in vivo. Adiponectin secretion was significantly suppressed by PRL and

Popular Abstract in Swedish Chefskap och ledarskap hos sjuksköterskor i högre chefsbefattningar inom hälso- och sjukvården. I dagens hälso- och sjukvård har sjuksköterskor i chefsposition en förändrad och utökad roll, bland annat till följd av decentraliserade organisationer och utökade ansvarsområden. Utvecklingen av omvårdnaden kommer till en del att vara beroende av chefernas förmåga och skickThe aim of this thesis was to illuminate the management and leadership of nurse managers within Swedish health care organizations and to recognize influencing factors of importance for the nurse managers in exercising and developing their management. The interviewees were all active in their positions at the time of the interviews. The nurse managers served at top management levels in either execu

Breast cancer incidence has markedly increased in Western countries for reasons that are not entirely understood. We characterized periodic and age-specific incidence trends of breast cancer in immigrants who migrated from low incidence areas to Sweden. The incidence in immigrants was compared to that in native Swedes and standardized incidence ratios (SIRs) were calculated, based on the Swedish F

The ECM exerts great effects on cells, and changed composition may therefore have profound impact. Small leucine-rich proteoglycans, e.g. fibromodulin, are essential in collagen assembly. Our aim was to investigate the role of fibromodulin in healthy and fibrotic lung parenchyma, theorizing that fibromodulin-deficient animals would be protected against fibrosis. Repeated subcutaneous bleomycin-inj

It can be said that literary texts do not have any obligation to reality, and that literature destabilises our relations to the everyday use of words and to established perspectives. Literature stands in relation to something that cannot be explained or conceptualised, and in this respect it is close to religion. I argue that many of these characteristics of literature are also features of philoso

The European Prospective Investigation into Cancer and. Nutrition (EPIC) is an ongoing multi-centre prospective cohort study designed to investigate the relationship between nutrition and cancer, with the potential for studying other diseases as well. The study currently includes 519 978 participants (366 521 women and 153457 men, mostly aged 35-70 years) in 23 centres located in 10 European count

This report demonstrates that in vitro activation of murine spleen cells with interleukin-2 (IL-2) or the bacterial superantigen staphylococcal enterotoxin A (SEA) results in different patterns of activation and function of cytotoxic cells. Lymphokine-activated killer activity and antibody-dependent cellular cytotoxicity (ADCC) are mainly mediated by IL-2 activated natural killer (NK) cells. SEA i

Most nitrogen and phosphorus transported by world rivers to the oceans is associated with dissolved organic matter. However, organic matter as a potential source of N and P has hitherto been largely neglected in studies of coastal microbial food webs. We examined 50 rivers, draining a major part of the Baltic Sea watershed, with respect to summer concentrations, chemical composition, and biologica

The aim of this study was to assess possible early determinants of idiopathic environmental intolerance (IEI), contributing to an integrated model for the development of IEI. Questionnaires concerning personality traits, current mental distress, subjective health complaints, work load and satisfaction, and options for recovery, were given to 84 persons from the general population attributing annoy

It is demonstrated that photographic images of plants can be produced in the absence of external illumination using an image intensifier. The image is produced by the weak delayed light emission (afterglow) from photosynthetically active chloroplasts. The use of such phytoluminographs is proposed for the study and diagnosis at an early stage of disturbances due to parasites, mineral deficiency, he

We show that the distance densities that can arise from a many-body wavefunction (i.e., are N-representable) lie in a convex set. We show that the N-representable distance densities have positive Fourier transforms.

Abstract The aim of this study was to evaluate a general school-based 1-year exercise intervention program in a population-based cohort of girls at Tanner stage I. Fifty-three girls aged 7–9 years were included. The school curriculum-based exercise intervention program included 40 minutes/school day. Fifty healthy age-matched girls assigned to the general school curriculum of 60 minutes physical a

OBJECTIVE: To analyse the outcome of selective management of patients with abdominal aortic aneurysms, the expansion patterns of the aneurysms, and the factors that influenced the rate of rupture. DESIGN: Retrospective study. SETTING: Malmo General Hospital, Lund University, Malmo, Sweden. SUBJECTS: 155 patients (96 men and 59 women) with abdominal aortic aneurysms who were not selected for operat

AIM: Non-participation in health surveys is a common phenomenon. When differences between participants and non-participants are considerable, the external validity of the sample survey may decrease and false conclusions might be drawn about the health status of the population. For this reason, the authors aimed to investigate the representativity of a postal questionnaire survey performed in the c
