Preparation of antifouling ultrafiltration membranes by addition of polyelectrolytes to the coagulation bath

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 fouling and cleaning challenge in the food industry

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

Key aspects of membrane plant operations related to 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

Desirable tourism transport futures

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

Multiplet bases, recursion relations and full color parton showers

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

Neurodevelopmental difficulties in children with idiopathic clubfoot

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

Bayesian Hierarchical modelling of goal side selection in a soccer penalty kicking task.

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

Bayes Factors: A ‘re-volution’ in psychology

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

Teaching Bayesian data analysis to psychology students

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

The ELT-MOS (MOSAIC) : Towards the construction phase

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

Celiaki som modell för autoimmun sjukdom. Transglutaminas har nyckelroll--stressreaktion sätter fart på ond cirkel

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

Screening för celiaki kan vara motiverad i högriskgrupper

Celiaki förekommer hos 0,5–1 procent av befolkningen. Majoriteten av dem med celiaki har atypiska symtom och är inte diagnostiserade. Personer med vissa kromosomrubbningar eller annan autoimmun sjukdom och nära släktingar till personer med celiaki tillhör riskgrupper där screening kan rekommenderas. IgA-endomysie- eller IgA-transglutaminasantikroppar har båda hög specificitet och hög sensitivitet Coeliac disease is widespread and occurs in 0.5-1 per cent of the population. Most sufferers show atypical symptoms and might well remain undiagnosed. Endomysial or human transglutaminase autoantibody levels of type IgA can be recommended as screening instruments combined with s-IgA for exclusion of such deficiency. In contrast, there is a high frequency of false-positive IgA gliadin antibody test

Dags att ifrågasätta managementkonsulternas trams

Managementkonsulternas lösningar saknar allt som oftast stabilt stöd i seriös forskning. Det borde egentligen vara högst kontroversiellt att chefer och politiker väljer att följa råden från dessa karriärister med begränsad erfarenhet, skriverJohan Alvehus, lektor vid Lunds universitet.
