The purpose of this work is to develop and implement a simple and robust preservation technology that can enhance food and economic security and thereby improve the lives of people in developing countries. The technique under development is termed “solar assisted pervaporation (SAP)”. It is a sustainable technology whereby fruit juices or purées are concentrated using reusable pouches made of “bre
Den 15 mars hoppade Felix Baumgartner från 22 km höjd. Detta var ett steg på vägen att slå det tidigare höjdrekordet: Joe Kittinger hoppade 1960 hoppade från en heliumballong på mer än 3 mils höjd, som en del av USAs rymdprogam. Att man kan komma så högt med en heliumballong, och sedan falla mot jorden, medan temperaturen varierar och luftens densitet och luftmotståndet hela tiden ökar, inbjuder t
Hopp från ballonger på flera mils höjd inbjuder till fysiksamtal.
Due to the increasing power requirement and the limited available space in vehicles, placing the heat exchanger at the roof or the underbody of vehicles might increase the possibility to handle the cooling requirement. A new configuration of the heat exchanger has to be developed to accommodate with the position change. In this paper, a countercurrent heat exchanger is developed for position on th

Many studies assume a respiratory quotient (RQ = molar ratio of CO2 produced to O2 consumed) close to 1 when calculating bacterioplankton respiration. However, evidence suggests that RQ depends on the chemical composition of the respired substrate pool that may be altered by photo-chemical production of oxygen-rich substrates, resulting in elevated RQs. Here we conducted a novel study of the impac
Specialiseringstjänstgöringen i Sverige har under de senaste åren genomgått genomgripande förändringar och ställer handledare av ST-läkare inför nya förutsättningar och utmaningar. Denna bok är skriven för handledare av läkare under utbildning och för alla som är intresserade av sådan handledning. Författarna utgår från de nya föreskrifterna och målbeskrivningarna och visar hur handledningen kan
Background: Ischemic stroke (IS) is a leading cause of death and disability worldwide. As genetic heritability for IS is estimated at about 35%-40%, the identification of genetic variants associated with IS risk is of great importance. The main objective of this study was to carry out a meta-analysis for polymorphisms in CRP, EPHX2, FGA, and NOTCH3 genes and the risk for IS. Methods: Literature se
Contactin genes CNTN5 and CNTN6 code for neuronal cell adhesion molecules that promote neurite outgrowth in sensory-motor neuronal pathways. Mutations of CNTN5 and CNTN6 have previously been reported in individuals with autism spectrum disorders (ASDs), but very little is known on their prevalence and clinical impact. In this study, we identified CNTN5 and CNTN6 deleteriousvariants in individuals
OBJECTIVE: To compare the clinical presentation of children with anorexia nervosa (AN group) with that of children with low-weight food intake disorder without weight and shape-related psychopathology (non-AN group). METHOD: Medical and psychiatric data were obtained from the case records of a consecutive series of 102 children with an eating disorder and a pronounced low weight who were below t
State-ownership has often been discussed as one of the major causes of poor industrial energy efficiency performance. This paper utilizes long-run historical data on the energy and material use in one specific industrial sector – the iron and steel production – in countries with both central-planning and market-based system, with a particular focus on former Czechoslovakia paralleled with the deve
Ischemic stroke is caused by occlusion of a cerebral artery, which gives rise to focal ischemia with irreversible injury in a core region and partially reversible damage in the surrounding penumbra zone. Stroke leads to neural death and consequently neurological impairments. Therapeutic intervention of stroke comprises thrombolysis and thrombectomy by chemical or surgical means, respectively. If d
Ischemia is defined as a reduction in blood flow to a level that is sufficient to alter normal cellular function. Brain tissue is highly sensitive to ischemia, such that even brief ischemic periods in neurons can initiate a complex sequence of events that may ultimately culminate in cell death. Stroke and cardiac arrest induce the cessation of cerebral blood flow, which can result in brain damage.
I forskningsrapporten presenteras en kvalitativ intervjustudie med företrädare för branschorganisationer (sakkunniga som representerar arbetsgivarsidan) inom privat sektor som totalt representerar drygt hälften av samtliga sysselsatta i Sverige.Syftet är att studera branschorganisationers förhållningssätt såväl till egna system för validering av den enskildes reella kompetensprofil som till generi
