Herein is reported an efficient catalytic system for the direct synthesis of styrene carbonate from styrene and CO2. The preparation and characterization of the catalyst using FTIR, TEM, EDX, XPS, and PXRD is presented. The catalyst comprised of nano-silver modified polyoxometalates (Agx/POM) and n-tetra butyl ammonium bromide (TBAB) was employed in the oxidative carboxylation of styrene with CO2

Isälvsstråket Djurkälla-Flädemo strax norr om Motala har undersökts med avseende på materialsammansättning, volym, täktverksamhet och motstående intressen till täkt. Naturvårdslagens betydelse för täktverksamhet och naturvårdshänsyn har diskuterats i perspektivet igår, idag, imorgon. Det undersökta isälvsstråket kommer att ingå i en översiktlig länsomfattande inventering av naturgrus och alternat

BACKGROUND: A synthetic oxytocin analogue, barusiban, was shown to potently inhibit oxytocin-induced activity of myometrium from term pregnant women. The responsiveness to vasopressin was not influenced by the compound. OBJECTIVE: To test the effect of barusiban and a reference compound, atosiban, on oxytocin-induced activity of myometrium from women at preterm pregnancy in comparison to myometriu

Popular Abstract in Swedish Denna avhandling i socialantropologi ägnas åt analysen av sociala och kulturella processer i Visaginassamhället efter sovjettiden. Visaginas (tidigare Sniechkus) byggdes under sovjettiden, åren 1975-1989, som hemvist för personal vid Ignalinas kärnkraftverk och deras familjer. De flesta invånarna i staden är ryssar som kom till Litauen mellan 1975 och 1989 för att byggaThis thesis focused on an examination of human agency and strategies for responding to rapid social and economic change. Fieldwork was carried out in the community of Visaginas town that was built during the Soviet period in Lithuania. The town is situated next to the Ignalina nuclear power plant. The majority of the town's inhabitants are Russians who immigrated to Lithuania from other areas of t

This study aimed to find out how the insulation of the footwear changes over one week of use. A thermal foot model with 8 measuring zones and 5 “sweat glands” was used for tests. A thin sock was donned on the model to allow better water distribution all over the foot surface. Four boots were tested over a period of 5 days. Each day was divided into 9 hour measurement period and 15 hour conditionin

Popular Abstract in Swedish Mjölk anses som det enda flytande livsmedlet som på naturlig väg innehåller de tre fundamentala byggstenarna, fett, protein och kolhydrater, vilket definierar ett livsmedel näringsmässigt. Majoriteten av världens vuxna befolkning är dock tvungen att ha en begränsad konsumtion av mjölk då toleransen för dess kolhydrat, laktos, minskar med vuxen ålder. Detta beror främst This thesis deals with the fermentation characteristics of lactic acid bacteria (LAB) in oat-based suspensions, with formulation work of fermented products based on oat and with nutritional studies of these products. Changes in structure in terms of viscosity and ropiness were studied when exopolysaccharide (EPS)-producing LAB strains, namely, Lactobacillus delbrueckii subsp. bulgaricus NCFB 2772,

Popular Abstract in Swedish Blodbildande stamceller förekommer i mänsklig benmärg i en frekvens på ca 1/100 000 celler. Med hjälp av cellytemarkörer, t.ex. CD34, kan man rena fram cellpopulationer som är anrikade på stamceller, men det saknas exakt kunskap om hur enskilda stamceller ser ut. De blodbildande stamcellerna har förmåga att vid celldelning antingen förnya sig själva eller att mogna ut. Hematopoietic stem cells (HSCs) have the capacity to maintain hematopoiesis throughout life. HSCs are ideal targets for permanent gene transfer, as the transgene will be expressed in all the progeny of the gene-modified stem cells. The aim of this thesis was to optimize conditions for retroviral gene transfer to human candidate HSCs and to study mechanisms interfering with efficient gene transfer.

The practice of service encounters in a district court, a home for the elderly, and a hotel Service management research places the service encounter in a central position. It is highlighted as a key event that involves the simultaneous production, consumption, and marketing of the services produced by the operation. However, in this research there is a tendency to discuss the service encounter in

The article uses embodiment and the experiential basis of conceptual metaphor to argue for the metaphorical essence of abstract legal thought. Abstract concepts like ‘law’ and ‘justice’ need to borrow from a spatial, bodily, or physical prototype in order to be conceptualised, seen, for example, in the fact that justice preferably is found ‘under’ law. Three conceptual categories of how law is con

Stretching DNA in nanochannels allows for direct, visual studies of genomic DNA at the single molecule level. In order to facilitate the study of the interaction of linear DNA with proteins in nanochannels, we have implemented a highly effective passivation scheme based on lipid bilayers. We show long-term passivation of nanochannel surfaces to several relevant reagents and demonstrate that the pe

To better understand how deformable and non-spherical particles behave in sorting devices based on deterministic lateral displacement we generate models of biological particles with tunable size, shape and mechanical properties using stop-flow lithography and we explore how these parameters play a role in our separation devices. Hollow and solid cylinders are compared with respect to their deforma

We present a simple and rapid microfluidic device capable of extracting and concentrating the parasite causing the fatal disease sleeping sickness (SS) from blood. The device is based on deterministic lateral displacement (DLD) and constructed with a single inlet with flow induced by an ordinary syringe. The simplicity is crucial as the device is intended for use in the resource depraved areas whe

Nodding syndrome is an emerging disease which have unknown transmission patterns and no properly established mechanisms for diagnosis leading to numerous hypothetical postulations. It has affected thousands of children in Uganda with debilitating effect and serious economic consequences. Spatial-temporal analysis may provide a quick mechanism to establish comparative understanding of the various h
