Organic farming may contribute substantially to future agricultural production worldwide by improving soil quality and pest control, thereby reducing environmental impacts of conventional farming. We investigated in a comprehensive way soil chemical, as well as below and aboveground biological parameters of two organic and two conventional wheat farming systems that primarily differed in fertiliza

We have investigated the role of lipid metabolism with regard to beta-cell function and insulin secretion. Lipids are known to play a crucial functional role in the pancreatic beta-cell, where they are essential for adequate hormone release, but may also exert a long-term toxic effect, leading to beta-cell dysfunction. Our studies in mice, where insulin resistance and glucose intolerance was induc

Purpose: Recently, there has been a growing interest in operating medical linear accelerators without a flattening filter Due to reduced scatter, leaf transmission and radiation head leakage a reduction of out-of-field dose is expected for flattening filter free beams. The aim of the present study was to determine the impact of unflattened beams on peripheral dose for advanced treatment techniques

Cloud condensation nuclei counter (CCNC) measurements performed at 14 locations around the world within the European Integrated project on Aerosol Cloud Climate and Air Quality interactions (EUCAARI) framework have been analysed and discussed with respect to the cloud condensation nuclei (CCN) activation and hygroscopic properties of the atmospheric aerosol. The annual mean ratio of activated clou

Objectives: The objective of this study was to define metabolic normality and to investigate the cardiometabolic profile of metabolically normal obese. Design: Cross-sectional study conducted at 21 research centers in Europe. Subjects: Normal body weight (nbw, n = 382) and overweight or obese (ow/ob, n = 185) subjects free from metabolic syndrome and with normal glucose tolerance, were selected am

Objective: The minor G allele of FOXO3A rs2802292 has been associated with longevity. We aimed to investigate whether a phenotype related to healthy metabolic aging could be identified in individuals carrying the longevity-associated FOXO3A rs2802292 G allele. Research Design and Methods: rs2802292 was genotyped in a phenotypically well-characterized population of young and elderly twins (n = 190)

The research presented in this thesis is primarily focused on experimental investigations of laser-driven ion acceleration from solid targets via the target normal sheath acceleration mechanism. In particular, ways of optimizing the absorption of the laser pulse energy by free plasma electrons in the target, or modifying the shape of the accelerating electron sheath were addressed. The aim of this

Introduction: Monoaminergic activity modulates nociceptive transmission in the central nervous system (CNS). Although pain is the most disabling symptom of osteoarthritis (OA), limited knowledge exists regarding the CNS mechanisms that amplify pain and drive sensitization processes in humans.Objectives:The main objective of this study was to evaluate associations between cerebrospinal fluid (CSF)

Popular Abstract in Swedish Det finns över 500 kräftarter i världen och vi hittar dem på alla kontinenter utom Antarktis och Arktis. I Sverige finns två arter, den inhemska flodkräftan och den introducerade signalkräftan. Signalkräftan introducerades till stor del för att ersätta förlusten av flodkräfta i många pestdrabbade vatten i södra Sverige. Att det just blev signalkräftan berodde främst på In this thesis I examine the dynamics of crayfish in streams and lakes. I have studied the influence of abiotic and biotic factors on abundance, growth, trophic position, niche breadth, and recruitment of crayfish, by conducting field studies, an outdoor channel experiment and timeseries analysis. Overall, the results show that abundance of crayfish is mostly affected by the abundance of predatory

Ammonia (NH3) is regarded as a promising future carbon-free fuel but needs to overcome drawbacks including extremely low burning velocity in practical combustion apparatus. In this study, ozone (O3) additive is used to elucidate one of the mechanisms of potential flame enhancement method based on plasma-assisted combustion. The effects of ozone addition on the laminar burning velocity of premixed

With an increased importance of working capital management and supply chain risks, supply chain finance has gained an increasing interest from organizations across the world. A buyer-centric supply chain finance solution can create a ‘win-win’ situation for buyers and suppliers, by allowing buyers to extend payment terms and suppliers to get payments in advance. This allows both buyers and supplie

Aims: Pre-capillary pulmonary hypertension (PHpre-cap) has a poor prognosis, especially when caused by pulmonary arterial hypertension (PAH) associated with systemic sclerosis (SSc-PAH). Whether cardiac magnetic resonance (CMR)-based quantification of atrial volumes in PHpre-cap is beneficial in risk assessment is unknown. The aims were to investigate if (i) atrial volumes using CMR are associated

Popular Abstract in Swedish Kroppens blodglukoskoncentration regleras av celler i de Langerhanska öarna i bukspottkörteln. β (beta)-celler frisätter insulin då sockerhalten i blodet ökar, tex efter en måltid. Insulin verkar via speciella membranbundna proteiner (receptorer) på celler i muskel, hjärta och fettväv och påverkar dessa att ta upp glukos från blodet. När blodsockerhalten sjunker, t.ex. We have investigated the in vitro effects of long-chain free fatty acids (FFAs) on mouse pancreatic α- and β-cells by a combination of electrophysiological recordings, intracellular Ca2+ ([Ca2+]i) microfluorimetry and hormone release measurements. Acute addition of the saturated FFA palmitate to intact islets doubled insulin as well as glucagon secretion in the presence of 1 or 15 mM glucose and t

To share belongings between friends is a common phenomenon. However, sharing as a business trend or even an economic system, in which unfamiliar individuals share assets and skills via online platforms, usually for a fee, is a newer phenomenon. The economic system is generally called “the sharing economy” or “collaborative consumption”. Characteristic for companies involved within the sharing econ

Syftet med den här uppsatsen är att ur ett civilrättsligt perspektiv undersöka hur de svenska civilrättsliga reglerna skyddar någon som riskerar att utsättas för barn- och tvångsäktenskap, samt olika myndigheters agerande och förhållningssätt när de möter någon som befinner sig i riskzonen för påtvingade äktenskap. En stor del av de äktenskap som ingås mot någons vilja berör parter som bor i oliThe purpose of this paper is to examine from a civil law perspective how the Swedish legislation protect anyone at risk for child and forced marriages, as well as how various government agencies intervene and approach situations when they meet someone who is at risk of forced marriage. A large part of the marriage entered against someone's will affect parties who live in different countries.

Acoustophoresis, i.e., the contactless manipulation of small cells or particles via acoustic waves is a gentle and label-free method that can, amongst others, be used to isolate rare cells such as circulating tumor cells from blood. To isolate enough cells, a large amount of sample needs to be processed in a reasonable amount of time. In a clinical setting, usually around 10 mL of blood can be col

In the future atmospheric CO2 concentrations might exceed 550 ppm according to the RCP8.5 scenario by mid-century from our current 410 ppm, while our world population is projected to surpass the 9.7 billion threshold within the same time span. This challenge leads to the raising of questions addressing future food security. Elevated CO2 has been shown to not only increase photosynthetic rates in

The European Union (EU) is heading for an increased economic, legal and political integration of its Member States. In spite of all the efforts to bring the people of Europe closer, significant differences in national laws and cultures still exist. Enhanced understanding of such disparities can create opportunities for companies operating on the EU market in several areas, including the way to dea
