The effect of the heat interaction between a water column and sediments on the formation, development, and duration of existence of anaerobic zones in ice-covered lakes is estimated based on observational data from five frozen lakes located in northwestern Russia and North America. A simple one-dimensional model that describes the formation and development of the dissolved oxygen deficit in shallo
The antibody response to the envelope proteins of hepatitis C virus (HCV) may play an important role in controlling the infection. To allow molecular analyses of protective antibodies, we isolated human monoclonal antibodies to the E2 envelope glycoprotein of HCV from a combinatorial Fab library established from bone marrow of a chronically HCV-infected patient. Anti-E2 reactive clones were select
Popular Abstract in Swedish De flesta barn som insjuknar i epilepsi tillfrisknar eller blir anfallsfria med hjälp av antiepileptisk medicin. Hos drygt en fjärde del av barnen blir epilepsin svårbehandlad och anfallskontroll är svår att uppnå. Dessa barn ska i första hand erbjudas möjlighet till epilepsikirurgisk utredning och behandling. När epilepsikirurgisk behandling inte är möjlig att utföra eWhen anti-epileptic drugs fail, and epilepsy surgery is found unfeasible or ineffective, there remains a group of at least 25% of children with epilepsy in whom seizure control cannot be achieved. Vagus nerve stimulation (VNS) is an adjunctive treatment for medically refractory epilepsy. It is an implantable, multi-programmable pulse generator that delivers current electrical stimulation to the va
Popular Abstract in Swedish Variabilitet i ett läkemedels farmakokinetiska (hur ett läkemedel omsätts i kroppen) och farmakodynamiska (vilken effekt ett läkemedel har) egenskaper kan resultera i att olika individer som erhållit samma dos av ett läkemedel får olika effekter av läkemedel. Biverkningar eller utebliven effekt kan innebära allvarliga konsekvenser för den enskilda individen. VariabiliteVariability in pharmacokinetic and pharmacodynamic parameters between individuals can be due to intrinsic and extrinsic factors. In this thesis three different areas regarding sources of variability have been investigated. 1. Formulation properties as an extrinsic source of variability. Lipophilic substances often have poor oral bioavailability and high inter- and intraindividual variability. High
This study assesses the effect of grants given to young Mexican researchers by the International Foundation for Science (IFS) on the development of their academic careers through an analysis of their publication output. Since 1974 IFS has supported similar to 4000 young scientists in developing countries conducting relevant and high quality research on the sustainable use of biological natural res
There are three relativization strategies in the Austroasiatic lang Kammu: (1) deletion of the relativized NP, (2) deletion & change of word order, & (3) pronominalization of the relativized NP. The use of these strategies for the six positions (subject, direct O, indirect O, oblique NP, genitive, & O of comparison) on the relativization hierarchy proposed by E. Keenan & B. Comrie
Popular Abstract in Swedish Avhandlingen är ett teologiskt studium av ett i biblisk litteratur säreget uttryck som angår livets mening: ”att ni skall bli delaktiga av gudomlig natur” (2 Petrus 1:4). Efter en analys av 2 Petrus 1:1-11 undersöks några utvalda texter tillgängliga vid första århundradet som behandlar temat ”att bli delaktiga av gudomlig natur”. Jämförande material utgörs av Gamla testThis book offers a theological study of an expression unique in biblical literature concerning the purpose of life: “that you might become sharers in divine nature” (2 Peter 1:4). Following an analysis of the text-immanent features in 2 Peter 1:1—11, the study delineates comparable notions of “sharers in divine nature” in selected writings that were current in the first century and contrasts these
An automated sample pretreatment of human blood plasma for liquid chromatographic determination of three antidepressant drugs, dibenzepine; a tricyclic antidepressant (TCA), reboxetine; a selective noradrenaline reuptake inhibitor (SNRI) and fluvoxamine; a selective serotonin reuptake inhibitor (SSRI), based on supported liquid membrane (SLM) for unsurpassed sample clean-up and analyte enrichment,
The pseudotetrasaccharide acarbose, previously known as a potent inhibitor of intestinal alpha-glucoside hydrolases, was investigated with regard to its influence on islet lysosomal enzyme activities and the insulin secretory processes. We observed that acarbose was a potent inhibitor of mouse islet lysosomal acid glucan-1,4-alpha-glucosidase activity, EC50 approximately 5 mumol/l, as well as of a
We present and investigate an extension of the classical random graph to a general class of inhomogeneous random graph models, where vertices come in different types, and the probability of realizing an edge depends on the types of its terminal vertices. This approach provides a general framework for the analysis of a large class of models. The generic phase structure is derived using generating f
Fat free extraction of polychlorinated biphenyls (PCBs) from fat containing food and feed matrices was achieved by selective pressurized liquid extraction using sulphuric acid impregnated silica inside 100 mL extraction cells on a Dionex ASE300. Data were compared to previous publications where extractions had been performed on a Dionex ASE200, with 33 mL cells and a Dionex ASE300, with 34 mL. In
In this paper, we show that the scheduling of tests on the test access mechanism (TAM) is equivalent to independent job scheduling on identical machines and we make use of an existing preemptive scheduling algorithm to produce an optimal solution in linear time. We extend the algorithm to handle (1) test conflicts due to interconnection tests and (2) cases when a test limits an optimal usage of th
Nitro blue tetrazolium (NBT) staining in normal rat retina was previously found to be affected by inhibition of free radical-related enzyme systems, indicating that NBT might be useful as a marker of free radicals. The aim of the present study was to investigate NBT staining in rat retina in vitamin E deficiency and after blue light exposure, and also to measure hydrogen peroxide (H2O2) production
