The current and future emissions regulations and demands on internal combustion engines have increased the need for improvement of the thermal design and engine ef ciency. This paper reports an initial investigation concerning in-cylinder heat transfer. In addition, a literature review in this eld is presented. It was found that no extensive application studies have been performed on full cylinder

Many aspects of human physiology and behavior are seasonally related. Although there are many studies using self-ratings of, for example, subjective health and stress, few involve adjusting effects for seasonal differences. To estimate the need of adjusting for season in field studies, 24 healthy men and women were studied in a design that required them to fill in questionnaires on one workday eve

This paper analyses a specific stage in the development of alignment system in Indo-European languages. It is argued that one of the most crucial stages is the appearance of binary features, which allows the language to develop into a form ready for dealing with complex functional demands.

Popular Abstract in Swedish Hjärnan är ett organ som utgör 2 % av kroppsvikten men som mottar ca 20 % av hjärtats minut volym och har en mycket hög energi konsumtion. I samband med en blodpropp i något av hjärnas blodkärl eller att ett av hjärnans kärl brister får man en stroke eller cerebral ischemi. Man har under många decennier inriktad sig på den akuta behandlingen på att finna ett sätt att reCerebral arteries participate actively in the response that follows an episode of cerebral ischemia in man and rat. It has been shown that the vascular endothelin receptor expression is increased in stroke and organ culture. Furthermore, studies have demonstrated the intracellular signalling pathways, leading to the enhanced expression of vascular endothelin receptors. We have revealed that both c

Stigma and discrimination are still prominent features of the life situation of persons with mental illness, adding to the burden of the illness, causing a lowered self-esteem, quality of life and affecting possibilities of adequate housing and work. It is also a major barrier to help seeking. The deinstitutionalization of mental health services has led to a significant increase in contacts betwee

Popular Abstract in Swedish Näthinnan (retina) ligger längst bak i ögat och fungerar som filmen i en kamera. Stavar och tappar registrerar ljus och signalen går via nerver till syncentra i hjärnan. Blodkärl löper genom näthinnan och förser cellerna med syre och näring samt transporterar bort slaggprodukter. Kärlsjukdomar, som t.ex. diabetes, blodproppar i näthinnan till följd av åderförkalkning ocRetinal ischaemia resulting from e.g. diabetes, vein thrombosis or arterial occlusion, is one of the major causes of visual impairment and blindness. Although new methods of treatment are being developed, there is still a need for more effective pharmacological forms of treatment. The aim of this work was to develop an appropriate animal model of retinal ischaemia in which the intracellular signal

Raoul Wallenberg har varit omdiskuterad såväl i Sverige som i utlandet efter hans försvinnande 1947. Uppmärksamheten för honom har gått i vågor. Ett särskilt fokus i artikeln är hur han framställs och brukas 2012, då hundraårsminnet av hans födelse uppmärksammas.

Objective: To study prescription patterns of biological treatment in rheumatoid arthritis ( RA) patients in southern Sweden, a region with no formal or economic restrictions for the use of biological treatment in rheumatological diseases. Specifically, we studied conformity with the national Swedish guidelines for biologics in RA. Methods: Rheumatologists in southern Sweden contribute to a volunta

I kanadensiska mi'kmaqberättelser, vilka nedtecknades under tiden som gruppen levde som jägare och samlare, finna flera skildringar av djur som flitiga agenter. Det finns till och med berättelser om äktenskap mellan människor och djur som dock alltid slutar olyckligt. Hur ska dessa berättelser läsas? Som nonsens eller säger de något om gränser och förhållningssätt till det vi i väst dikotomiserat

Trigonal-planar, middle transition metal diiminato-imido complexes do not exhibit high-spin states, as might be naively expected on the basis of their low coordination numbers. Instead, the known Fe(III), Co(III), and Ni(III) complexes exhibit S = (3)/(2), S = 0, and S = (1)/(2), ground states, respectively. Kohn-Sham DFT calculations have provided a basic molecular orbital picture of these compou

Urothelial carcinoma shows frequent amplifications at 6p22 and 1q21-24. The main target gene at 6p22 is believed to be E2F3, frequently co-amplified with CDKAL1 and SOX4. There are however reports on 6p22 amplifications that do not include E2F3. Previous analyses have identified frequent aberrations occurring at 1q21-24. However, due to complex rearrangements it has been difficult to identify spec

Abstract COPD is a major cause of chronic morbidity and mortality throughout the world. It is a preventable and treatable disease. Smoking is the most commonly encountered risk factor for COPD and the habit now unfortunately starts at earlier ages than before. There is a strong necessity to diagnose COPD in early stages before symptoms present themselves. MRI with hyperpolarized 3He using diffusio

Background: Migration is important for the metastatic capacity and thus for the malignancy of cancer cells. There is limited knowledge on regulatory factors that promote the migration of neuroblastoma cells. This study investigates the hypothesis that protein kinase C (PKC) isoforms regulate neuroblastoma cell motility. Methods: PKC isoforms were downregulated with siRNA or modulated with activato

This paper concerns mathematical modeling and computational fluid dynamics of back-shocking during hollow fibre ultrafiltration of dextran T500. In this paper we present a mathematical model based on first Principles, i.e., solving the Navier-Stokes equation along with the continuity equation for both the solute and the solvent. We investigate the validity of the estimate On the optimal back-shock
