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
Aim: To evaluate neurodevelopmental difficulties in children with idiopathic clubfoot. Method: A cross-sectional study of 106 children (29 females, 77 males; aged 8–10y) with idiopathic clubfoot and 109 age-, sex-, and residential area-parallelized children from the general population. Neurodevelopmental difficulties were assessed using the parent-report Five to Fifteen (FTF) questionnaire. Group
The present study investigates goal side selection in soccer penalty kicking. Given the task of choosing which side of a soccer goal to best score, participants viewed realistic images of a soccer goal and goalkeeper. The goalkeeper’s position was systematically displaced along the goal line, and the lateral position of the goalmouth was systematically displaced in each image – to simulate changes
In psychology, Bayes Factors (BFs) are being increasingly reported as a complement to p-values. However, just as the mindless computation of p-values encourages a simple dichotomization of study results, the mindless computation of BFs with an overemphasis on hypothesis testing detracts from more useful approaches to interpreting study results, such as parameter estimation. BFs may serve to facili
Bayesian methods of data analysis are increasingly being adopted in psy-chology and across the social sciences. Yet, attempts to teach Bayesian dataanalysis to the psychology students in Lund has met with many challenges.In this talk, I shall lay out the current progression of statistics teaching fromfirst year undergraduate to master level. Recent attempts to introduce Bayesianmethods of data ana
When combined with the huge collecting area of the ELT, MOSAIC will be the most effective and flexible Multi-Object Spectrograph (MOS) facility in the world, having both a high multiplex and a multi-Integral Field Unit (Multi-IFU) capability. It will be the fastest way to spectroscopically follow-up the faintest sources, probing the reionisation epoch, as well as evaluating the evolution of the dw
The autoantigen of endomysial antibodies in coeliac disease has been found to be an enzyme, tissue transglutaminase. Zinc inhibits the calcium-dependent activation of this thiol enzyme and also decreases the affinity between transglutaminase and the antibodies. Physiologically, transglutaminases catalyse the formation of bridges between lysine- and glutamine-containing peptides. Theoretically, if
