Anion exchange membranes (AEM) are central materials in different energy storage and conversion devices such as alkaline fuel cells, electrolysers and flow batteries. The properties of the AEM therefore has a direct impact on the performance and life-time of the devices. As a polymeric electrolyte film that separates the two electrodes, the AEM is required to have good mechanical properties, high

Lithium-ion batteries (LIBs) have received increasing attention as power sources in electric vehicles. In commercial LIBs, the electrolyte consists of lithium salts dissolved in flammable organic solvents, which raises safety concerns because catastrophic failure of LIBs often begins with the ignition of these solvents.1 Furthermore, these solvents have poor electrochemical stability, resulting in

Patients suffering from inflammatory conditions often present with severe hypovolemia due to vasodilatation and increased vascular permeability. Early administration of fluids is, therefore, a cornerstone and lifesaving therapy.However, a vigorous and aggressive fluid therapy increases tissue edema, worsen tissue perfusion and organ function. Based on this, the presented studies investigated diffe

BACKGROUND: Even though crystalloids are the first choice for fluid resuscitation in hemodynamically unstable patients, their potency as plasma volume expanders in hypovolemia of different etiologies is largely unknown. The objective of the study was to investigate dose-response curves of a crystalloid in hypovolemia induced by either sepsis or hemorrhagic shock.RESULTS: Rats were randomized to re

In previous in-vivo studies we have presented indirect evidence for the involvement of islet acid glucan-1,4-alpha-glucosidase (acid amyloglucosidase), a lysosomal glycogen-hydrolysing enzyme, in certain insulin secretory processes. In the present combined in-vitro and in-vivo investigation, we studied whether differential changes in islet acid amyloglucosidase activity were related to the insulin

Today, commercially used brasses commonly contain 2 to 4 wt% lead. As the availability of low-lead and lead-free brass increases, there are environmental incentives for investigating the consequences of replacing the lead-containing brasses with lead-free equivalents. Generally, lead-free brass is expected to have a lower machinability than its lead-alloyed counterpart, implying a higher manufactu

Access to compatible blood for transfusion is a prerequisite for modern health care. The compatibility is limited by the presence of antibodies to blood group antigens, polymorphic protein and carbohydrate structures, on the surface of the red blood cell. Blood group antigens arise from genetic variation in the genes underlying their expression. Knowledge of these genes and their variation can fac

This thesis explores crystal-phase engineering of nanowires to fabricate advanced quantum structures for charge and spin transport studies. Quantum dots formed by crystal-phase tuning during epitaxial growth of InAs nanowires were used as a starting point to realize and electrically characterize two different types of parallel-coupled quantum dots; electron-hole quantum dots and electron-electron

Även om vi skulle lyckas minska de globala utsläppen av växthusgaser, så finns det ett angeläget behov att anpassa samhället för att kunna motstå klimatförändringens skadliga effekter. Denna process kallas klimatanpassning. Städer står inför särskilda risker från klimatförändringen och nuvarande tillvägagångssätt, som ofta förlitar sig på tekniska lösningar och toppstyrd implementering, bedöms intEven if current attempts to reduce global greenhouse gas emissions would succeed, society-wide adjustment to the harmful effects of climate change is urgently needed. This process is known as climate adaptation. Cities face particular risks from climate change, and there is increasing evidence that traditional approaches, which have often relied on technical solutions and top-down management struc

Change has often been said to characterise retailing, and research on retail change is extensive. However, though much of that research has focused on retail formats, it has not sufficiently addressed the fluid nature of retailing and how its formats emerge. This paper offers a more dynamic conceptualisation of retail format change by introducing the concept of retail formation. Taking a construct

Semiconductor nanowire solar cells have achieved comparable efficiency to their planar counterparts with substantial reduction of material consumption. Tandem geometry is a path towards even higher efficiency. However, extensive studies are needed to reach this goal. My study started from the building blocks of the materials used in the upper cell, namely GaInP nanowires. The growth and doping con

OBJECTIVE: To determine whether probiotic prophylaxes reduce the odds of Clostridium difficile infection (CDI) in adults and children. DESIGN: Individual participant data (IPD) meta-analysis of randomized controlled trials (RCTs), adjusting for risk factors. METHODS: We searched 6 databases and 11 grey literature sources from inception to April 2016. We identified 32 RCTs (n=8,713); among them, 18

A broad measurement range of glucose is often required in clinical analysis, especially for diabetic patients where glucose levels can be very high. Pyrroloquinoline quinone glucose dehydrogenase (PQQGDH) has previously been used in electrochemical quantification of glucose with an extended linear range. However, in real sample determination of glucose, interferences from electroactive substances

Continental European jurisdictions have introduced corporate opportunities rules inspired by Anglo-American law. Despite a certain degree of homogeneity in substantive law, their monetary remedial systems still differ in common law and civil law jurisdictions. These differences matter because of the deterrence function connected to corporate opportunities remedies – deterrence being the core of fi

Sugar sweetened beverages (SSB), artificially sweetened beverages (ASB), juice, coffee and tea has been associated with risk of metabolic disease. High consumption of these beverages may be associated with certain characteristics of the overall diet that would be important to take into account when analysing beverage-disease associations. Here, we investigate five beverages and their association w

In order to study longitudinal movement and intramural shearing of the arterial wall with a Lagrangian viewpoint using ultrafast ultrasound imaging, a new tracking scheme is required. We propose the use of an iterative tracking scheme based on temporary down-sampling of the frame-rate, anteroposterior tracking, and unbiased block-matching using two kernels per position estimate. The tracking schem

Background: The aim of this study was to investigate the oxygen consumption of explanted aerobically-perfused cardioplegic porcine hearts at different temperatures. Material/Methods: Explanted hearts from 30 pigs weighing 50 kg were randomized into 5 groups. The hearts received continuous antegrade perfusion within a temperature-controlled sealed system. The perfusate consisted of an albumincontai
