Halomonas boliviensis is a moderate halophilic bacterium, isolated from a soil sample around a hypersaline lake Laguna Colorada in the Andean region of Bolivia. The organism is capable of growing over a wide range of NaCl concentration (0-25 %, w/v), however with an optimum of about 4.5 % (w/v) NaCl. It is able to accumulate two useful products: poly(3-hydroxybutyrate) (PHB) and ectoines (ectoine
Clinical trials of pharmaceuticals have been running in Russia for more than ten years and while it is an attractive location for research, it remains a largely untapped resource as researchers look to expand patient recruitment outside the Western world. While academic sites like Moscow, St Petersburg and Novosibirsk have all gained experience in clinical trials, smaller hospitals in peripheral
We have developed the novel Aerosol Dynamics, gas- and particle-phase chemistry model for laboratory CHAMber studies (ADCHAM). The model combines the detailed gas-phase Master Chemical Mechanism version 3.2 (MCMv3.2), an aerosol dynamics and particle-phase chemistry module (which considers acid-catalysed oligomerization, heterogeneous oxidation reactions in the particle phase and non-ideal interac
Plant-based beverages are increasing in popularity and quinoa is an attractive option. A hygienic implication linked to the production of beverages from raw material originating from plants is the high microbial contamination. The safety of the product can be guaranteed by lactic acid fermentation, and by using a probiotic strain as starter culture for the fermentation, the final product will bene
Growing planets interact with their natal protoplanetary disc, which exerts a torque onto them allowing them to migrate in the disc. Small mass planets do not affect the gas profile and migrate in the fast type-I migration. Although type-I migration can be directed outwards for planets smaller than 20−30M⊕ in some regions of the disc, planets above this mass should be lost into the central star lo
The novel method of modification of polyethersulfone (PES) ultrafiltration membranes is proposed. This method involves the use of aqueous solutions of polyacrylic acid (PAA) of different molecular weights (Mn=5.1×103 g·mol–1, Mn=490×103 g·mol–1) as a coagulant in non-solvent induced phase inversion process (NIPS). Addition of PAA (0.05–1.5 wt%) to the coagulation bath leads to marked changes in pe
Background: Subgroups of adult-onset diabetes, namely severe autoimmune diabetes (SAID), severe insulin-deficient diabetes (SIDD), severe insulin-resistant diabetes (SIRD), and mild obesity-related diabetes (MOD) or mild age-related (MARD) diabetes, have been defined with clinical variables and a machine-learning approach. Our aim was to describe their long-term outcomes and mortality. Methods: In
Background The dura mater has a permeable vasculature similar to that of peripheral organs, and is separated from the brain, which is enclosed within the arachnoid barrier. Fluid and solute transport across the arachnoid barrier between the subarachnoid space (SAS) and dura is crucial for brain waste clearance and immune surveillance, but few neuroimaging approaches can capture this dynamic proces
Premise: Flower color, a key trait influencing plant–pollinator interactions, may be influenced by abiotic factors such as soil. We investigated association between pollinators, soil characteristics, and flower color variations in Digitalis purpurea across native populations in Sweden and introduced populations in Bolivia. Methods: We measured floral traits, reflectance of petals and nectar-guide
Popular Abstract in Swedish El-avfall (avfall från elektriska och elektroniska produkter) har under det senaste årtiondet blivit ett växande miljöproblem också i de mindre rika länderna (icke-OECD länder). Informell återvinning i u-länder har lett till att giftiga ämnen, som t.ex. bly och kvicksilver från tv-apparater, PVC från sladdar och bromerade flamskyddsmedel från plastkomponenter, har läcktWaste electrical and electronic equipment (WEEE) has become a salient issue in non-OECD countries. With a growing awareness about serious damages to the environment and human health from a lack of safe treatment and recycling of WEEE, there has been a search for policy responses in several of these countries. This research finds that extended producer responsibility (EPR), a policy principle that
Background: B-vitamins are essential for one-carbon metabolism and have been linked to colorectal cancer. Although associations with folate have frequently been studied, studies on other plasma vitamins B2, B6, and B12 and colorectal cancer are scarce or inconclusive. Methods: We carried out a nested case-control study within the European Prospective Investigation into Cancer and Nutrition, includ
The main purpose of this thesis was to examine various factors influencing starch retrogradation. The reassociation events of starch, which are closely linked to the staling of bakery products, were mainly studied by thermal analysis. Some aspects of starch gelatinization are also included. The gelatinization and retrogradation were described as non-equilibrium processes where the phase transition
Plant cells carry Ca2+ ATPases to maintain the low resting level of cytosolic Ca2+ (0.1-0.2 µM) found in all eukaryotes. Plant Ca2+ ATPases are mainly located in the plasma membrane, the endoplasmic reticulum and in the vacuolar membrane, and consequently large Ca2+ gradients are created across these membranes. The Ca2+ gradients are used by the cell to transmit information in a variety of physiol
This dissertation addresses the topic of descriptions in conversation: a relatively unexplored area of investigation apart from a small number of studies within the field of conversation analysis (Mondada 1998, 1999). However, whereas previous studies focus on the description as a social activity, enhancing the conversational facet, the present work has as a premise to put emphasis on the descript
Silicon is the next most abundant element in the Earth’s crust and its biogeochemical cycle is linked with that of carbon. Further, silicon is a beneficial nutrient for plants in terrestrial ecosystems and a key nutrient for diatoms in aquatic ecosystems. During the last decade the important role of terrestrial vegetation in controlling Si fluxes downstream aquatic environments, via incorporation
Popular Abstract in Swedish Varför beslutar politiker ibland att vidta till synes effektlösa åtgärder? Varför uppstår ibland stora politiska konflikter i små frågor? I vanliga fall vidtar man en politisk åtgärd därför att man eftersträvar det konkreta resultatet av åtgärden. Symbolpolitik är när en politisk fråga blir viktig, inte beroende på vad den konkret innebär och leder till, utan på grund aSymbolic politics is the degree to which political decision-making is motivated, not by the tangible aspects of the decision, but by the interpretation of what the decision represents symbolically. While symbolic politics is widely recognized as an important aspect of political decision-making, the phenomenon is insufficiently explored in political science. The first aim of the present dissertatio
With the attempts to achieve higher thermal efficiency, turbine blades are exposed to very high temperature gases and may undergo severe thermal stress and fatigue. Thus, in order to develop optimal cooling strategies and reduce the heat transfer it is important to obtain a good understanding of both the complex flow field and the heat transfer characteristics in turbine rotor/stator hot-gas passa
Popular Abstract in Swedish Länder som strävar efter att kvalificera sig för medlemskap i Europeiska unionen måste genomföra omfattande reformer under kort tid. Som en effekt av anpassningsprocessen till unionens regelverk och politiska, ekonomiska och administrativa kriterier omstruktureras statsapparaten. Detta gäller inte minst i de kandidatländer som samtidigt genomgår radikala transformationsIt is generally recognized that the EU accession process has profound effects on state transformation in the postcommunist applicant countries. A key problem of postcommunism has been a weak ability to implement public policy. This study explores how efforts to fulfill EU conditionality may influence implementing capacity. Firstly, it advances a theoretical framework for this purpose, focusing on
In the present work a detailed kinetic soot model is applied to study the formation and oxidation of soot particles in laminar premixed and turbulent non-premixed flames. The soot model used in this study is based on a detailed description of the chemical and physical processes involved in the formation of soot. In the first part of the study the soot model is extended to include the formation of
