Sex differences in parasite load and immune responses are found across a wide range of animals, with females generally having lower parasite loads and stronger immune responses than males. Intrigued by these general patterns, we investigated if there was any sign of sex-specific selection on an essential component of adaptive immunity that is known to affect fitness, the major histocompatibility c
In this paper, we perform a threshold analysis of braided convolutional codes on the additive white Gaussian noise (AWGN) channel. The decoding thresholds are estimated by Monte-Carlo density evolution techniques and compared with approximate thresholds from an erasure channel prediction. The results show that, with spatial coupling, the predicted thresholds are very accurate and quickly approach
De moderna kvinnorna med korta kjolar och ännu kortare hår som jazzade sig igenom 1920-talets nöjesliv är en bild som reproduceras i populärkulturen än idag. Men de moderna kvinnorna sågs i sin samtid inte endast som nöjeslystna kommersiella produkter, utan användes som en arena för att diskutera frågor om nationalitet, rasbiologi, genus, kropp och det moderna samhällets utmaningar. De moderna kvi
Background ST-elevation myocardial infarction (STEMI) occurs as a result of rupture of an atherosclerotic plaque in the coronary arteries. Limited data exist regarding the impact of culprit coronary vessel on hard clinical event rates. This study investigated the impact of culprit vessel on outcomes after primary percutaneous coronary intervention (PCI) of STEMI.Methods A total of 29 832 previousl
The retail industry is looking for new ways to compete as digitalization and non-traditional actors are changing the game. In an industry where constant improvements are key and studies of innovation management are scarce - this qualitative study of four retail firms addresses how innovation is currently perceived and managed. As a result, we have found that innovation is an uncommon theme and the
Most of the literature accumulated around retail change derive a linear, progressive understanding, typically coined with the term “retail evolution”. Once it is formulated as such, a need for adopting a historical perspective to study present becomes superfluous, because the past is understood as something that is left behind, something incapable of making an impact on the present. In this resear
Membrane cleaning is an integrated part of the daily membrane plant operation in the food and biotech industry. However, the impact of membrane cleaning on the plant operations and economics are often neglected parameters in the development of new applications despite the fact that the cost for membrane cleaning is a dominating membrane operating expenditure apart from electricity. The aim of this
Universitet och högskolor är unika myndigheter i Sverige genom att ha en demokratisk styrning med stark representation från verksamheten. I universitetsstyrelsen finns visserligen mer politiskt tillsatta ledamöter och representanter för det omgivande samhället, men bara ett steg längre ned på fakultetsnivå, som vår egen fakultet, är verksamhets- representationen i det närmaste total. V
BACKGROUND: Copper and zinc are essential micronutrients and cofactors of many enzymatic reactions that may be involved in liver-cancer development. We aimed to assess pre-diagnostic circulating levels of copper, zinc and their ratio (Cu/Zn) in relation to hepatocellular carcinoma (HCC), intrahepatic bile duct (IHBD) and gall bladder and biliary tract (GBTC) cancers.METHODS: A nested case-control
The pulp and paper industry is one of the most important industrial sectors worldwide. The focus of current pulp mills is on the production of cellulose pulp fibres and electricity. By converting traditional pulp mills into biorefineries they can be a keystone in a future bioeconomy based on renewable resources instead of fossil fuels. In order to achieve this, pulp mills have to close their loops
Nowadays, the main challenge in designing ultrafiltration membranes is increasing membrane fouling resistance without sacrificing membrane transport properties. Novel method of modification of ultrafiltration membranes using aqueous solutions of commercially available cationic and anionic polyelectrolytes based on acrylamide copolymers is proposed. Polyelectrolytes based on acrylamide copolymers a
The human immune system is very powerful, and if it is directed towards ourselves, it can lead to the very serious so-called autoimmune diseases
When applying membrane processes on industrial scale in the food industry both the fouling and the subsequent cleaning of the membranes are key but often underestimated factors. This presentation will focus on the impact of pre-treatment, operation conditions and module design on fouling and cleaning.After reviewing the current state-of-the-art of membrane fouling and cleaning in the food industry
Fouling is one the most important challenges to apply membrane technology on industrial scale in the food industry. Despite significant progress in understanding and preventing fouling and in developing appropriate membrane cleaning protocols, both fouling and cleaning remain key challenges in membrane plant operation in the food industry with a significant impact on membrane plants capital (CAPEX
The challenge of mitigating climate change is critical to desirable tourism transportation futures, although to date relatively little attention has been paid to this aspect of sustainable tourism. This introductory article to the special issues on ‘Desirable Tourism Transport Futures’ explores approaches to transitioning the tourism sector to a sustainable emissions path. It starts by describing
Vad består materia av? Det är en fundamental fråga som mänskligheten försökt besvara i tusentals år. Vårt svar på den frågan har utvecklats enormt de senaste 200 åren. Atomer, från grekiskans ord för odelbar, bygger upp materian vi ser omkring oss. Det antogs längeatt atomer verkligen var odelbara, men strax innan sekelskiftet år 1900, kom experimentellt bevis från J. J. Thomson, som påvisade att The papers in this thesis all concern the treatment of colors in perturbative QCD, both in the context of hard scattering cross sections and for parton showers. The complexity of the color structure of QCD increases quickly with the number of external partons. One way of tackling this issue is by using an orthogonal, group theory based, type of bases, called multiplet bases. This is the topic of p
