In this work, a novel analytical method based on hollow fiber liquid phase microextraction (HF-LPME) and high performance liquid chromatography (HPLC) was developed for the analysis of melamine in fresh milk. The conditions of the HF-LPME were investigated and optimized. As a result, a supported liquid membrane containing 6-undecanone and di-2-ethylhexyl phosphoric acid (D2EHPA) was selected. The

According to the Argument from Disagreement (AD) widespread and persistent disagreement on ethical issues indicates that our moral opinions are not influenced by moral facts, either because there are no such facts or because there are such facts but they fail to influence our moral opinions. In an innovative paper, Gustafsson and Peterson (Synthese, published online 16 October, 2010) study the arg

The influence of module configuration on the ultrafiltration of highly concentrated fluids in tubular membrane plants was investigated. Previous work has shown that frictional pressure drop in the feed flow channel can have a significant influence on the performance when treating viscous fluids. In the present study, three module alternatives were compared: polymeric membranes connected either in

Cleft lip and palate (CLP), the most common of all craniofacial anomalies, has an incidence about 2 per 1000 births in the Scandinavian countries. The Department of Plastic and Reconstructive Surgery in Malmö has been a regional centre in southern Sweden for the treatment of patients with CLP since 1954 with about 40 new cases of clefts each year. Speech and facial growth are important objectives

Background. Over the last few decades, an increasing number of studies have suggested a connection between neurodevelopmental problems (NDPs) and body mass index (BMI). Attention deficit/hyperactivity disorder (ADHD) and autism spectrum disorders (ASD) both seem to carry an increased risk for developing extreme BMI. However, the results are inconsistent, and there have been only a few studies of t

We discuss two examples of infinite random graphs obtained as limits of finite statistical mechanical systems: a model of two-dimensional dis-cretized quantum gravity defined in terms of causal triangulated surfaces, and the Ising model on generic random trees. For the former model we describe a relation to the so-called uniform infinite tree and results on the Hausdorff and spectral dimension of

The human hand has so many degrees of freedom that it may seem impossible to control. A potential solution to this problem is "synergy control" which combines dimensionality reduction with great flexibility. With applicability to a wide range of tasks, this has become a very popular concept. In this review, we describe the evolution of the modern concept using studies of kinematic and force synerg

This is the first study on freeze-dried foams prepared from glutenin- and gliadin-rich fractions of wheat gluten and blends thereof. It was found that the foam density and stiffness could be controlled by a suitable choice of the glutenin/gliadin ratio. The glutenin-rich samples had the highest foam densities and the density decreased with increasing gliadin content. The compression modulus also d

This work compares the extent of linear response regions from standard time-resolving optical detectors for phosphor thermometry. Different types of photomultipliers (ordinary and time-gated) as well as an avalanche photodiode were tested and compared using the phosphorescence decay time of cadmium tungstate (CdWO4). Effects originating from incipient detector saturation are revealed as a change i

The interfacial behavior of aqueous solutions of four different neutral polymers in the presence of sodium dodecyl sulfate (SDS) has been investigated by surface tension measurements and ellipsometry. The polymers comprised linear poly(ethylene oxide) with low and high molecular masses (10 (3) and 10 (6) Dalton (Da), respectively), and two high molecular mass methacrylate-based comb polymers conta

Abstract The present thesis explored the epidemiology of intracerebral haemorrhage (ICH), i.e., factors associated to incidence and prognosis. In the population of Malmö (Malmö 1990 cohort), it was shown that immigrants from China/Vietnam and the Former Soviet Union had higher risk of ICH than citizens born in Sweden. Although hypertension is a well-known risk factor for stroke, the relation

Popular Abstract in Swedish Hjärt- kärlsjukdomar är den vanligaste dödsorsaken i Sverige. Den bakomliggande orsaken till de allra flesta fall av hjärt- kärlsjukdom är vad som i vardagligt tal kallas åderförkalkning. Den medicinska termen för åderförkalkning är ateroskleros. Ateroskleros är en inflammatorisk sjukdom i artärerna som orsakas av att LDL-partiklar, det så kallade onda kolesterolet, ansThe immune system is a promising target for novel therapies that are aiming at reducing cardiovascular diseases. Autoimmune responses against modified low density lipoprotein (LDL) are believed to promote development of atherosclerosis. Proinflammatory immune responses can be counterbalanced by immunosuppressive regulatory T cells (Tregs). Immunizations of hypercholesterolemic mice with oxidized L

Trait anxiety, working memory capacity, and the effectiveness of memory suppression. Scandinavian Journal of Psychology. We aimed at replicating the finding that humans are able to suppress unwanted memories, and tested whether this ability varies with individual differences in working memory capacity, trait anxiety and defensiveness. In a think/no-think experiment, participants either recalled or

We report the synthesis of thermosensitive raspberry-like hybrid microgels. They consist of a poly(N-isopropylacrylamide) core decorated with in situ formed silica particles. A linking silane agent was copolymerized to help the anchoring of silica particles formed by a controlled silica precursor addition onto the outer shell. The thermosensitive behaviour is tuneable by adjusting the size of the

Molecularly imprinted polymers (MIPs) targeting quercetin were prepared from 4-vinylpyridine and ethylene dimethacrylate (EDMA) under various solvent systems with the aim to form MIPs with high recognition for the quercetin molecule in aqueous systems at high temperature. A MIP prepared from the three-component solvent mixture of THF/H2O/MeOH showed potential in its application for the determinati

LACM 128319, which was collected in western Kansas, U. S. A., and is assignable to Platecarpus tympaniticus (Mosasauridae, Plioplatecarpinae), represents arguably one of the most exquisite mosasaur specimens known to date. Measuring 5.67 m from the tip of the snout to the end of the tail, it comprises an exceptionally well-articulated skeleton, accompanied by soft-tissue remains, such as skin impr

De vanligtvis beaktade fossilfria alternativen till dagens olje- och fossilgasbaserade drivmedel i transportsektorn är förnybar el, vätgas och biodrivmedel. De begränsningar, osäkerheter och problem som finns med batterier, vätgas och biodrivmedel gör det intressant att beakta möjligheterna att från el producera kolhaltiga drivmedel – flytande och gasformiga kolväten. Dessa så kallade elektrobräns
