Ionic-Charge Dependence of tie Intermolecular Coulombic Decay Time Scale for Aqueous Ions Probed by the Core-Hole Clock
Auger electron spectroscopy combined with theoretical calculations has been applied to investigate the decay of the Ca 2p core hole of aqueous Ca2+. Beyond the localized two-hole final states on the calcium ion, originating from a normal Auger process, we have further identified the final states delocalized between the calcium ion and its water surroundings and produced by core level intermolecula

Determination of Melamine in Fresh Milk with Hollow Fiber Liquid Phase Microextraction Based on Ion-Pair Mechanism Combined with High Performance Liquid Chromatography
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
Do computer simulations support the Argument from Disagreement?
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
Influence of module configuration on total economics during ultrafiltration at high concentration
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. CLINICAL STUDIES REGARDING SPEECH AND FACIAL GROWTH
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
Neurodevelopmental problems and extremes in BMI.
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
Infinite Random Graphs as Statistical Mechanical Models
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
Neural bases of hand synergies
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
Novel freeze-dried foams from glutenin- and gliadin-rich fractions
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
Comparison of photo detectors and operating conditions for decay time determination in phosphor thermometry
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
Competitive Adsorption of Neutral Comb Polymers and Sodium Dodecyl Sulfate at the Air/Water Interface.
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

The Epidemiology of Intracerebral Haemorrahge. Risk factors and prognosis
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

Protective Immunity in Atherosclerosis
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
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
Hybrid raspberry microgels with tunable thermoresponsive behavior
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
