Plasma fibrinogen concentration is important for coagulopathy assessment, and is most commonly measured using the Clauss method. Several factors, including device type and reagent, have been shown to affect results, The study objective was to evaluate performance and repeatability of the Clauss method and to assess differences between measurements performed during and after cardiopulmonary bypass

Abstract in UndeterminedIn this paper, the problem of jointly estimating the number of harmonics and the fundamental frequency of periodic signals is considered. We show how this problem can be solved using a number of methods that either are or can be interpreted as filtering methods in combination with a statistical model selection criterion. The methods in question are the classical comb filter

Objective: By retarding fat digestion, thylakoids, the internal photosynthetic membrane system of green plants, promote the release of satiety hormones. This study examined the effect of consuming a single dose of concentrated extract of thylakoids from spinach on satiety, food intake, lipids, and glucose compared to a placebo. Design: Sixty overweight and obese individuals enrolled in a double-bl

Human a-lactalbumin made lethal to tumor cells (HAMLET) and its analogs are partially unfolded protein-oleic acid (OA) complexes that exhibit selective tumoricidal activity normally absent in the native protein itself. To understand the nature of the interaction between protein and OA moieties, charge-specific chemical modifications of lysine side chains involving citraconylation, acetylation, and

The dependence of the rate of proton-proton interactions on the centre-of-mass collision energy, root s, is of fundamental importance for both hadron collider physics and particle astrophysics. The dependence cannot yet be calculated from first principles; therefore, experimental measurements are needed. Here we present the first measurement of the inelastic proton-proton interaction cross-section

A combination of NMR chemical shift imaging and self-diffusion experiments is shown to give a detailed molecular picture of the events that occur when tablets of hydrophobically modified poly(acrylic acid) loaded with a drug (griseofulvin) swell in water in the presence or absence of surfactant (sodium octylbenzenesulfonate). The hydrophobic substituents on the polymer bind and trap the surfactant

This paper examines a long run macroeconomic dilemma. This dilemma states that given a real appreciation, i.e. a continuous increase in the real exchange rate, an economy has two options open with respect to inflation and nominal exchange rate. Either the economy chooses a fixed exchange rate- regime but has to allow for a rising inflation. Or the economy can choose an inflation targeting- regime,

I examine the impact of several determinants on foreign direct investments (FDI) by conducting a regional analysis with a particular focus on Belarus. I estimate a panel data model for 16 Central and Eastern European and ex-Soviet Union member countries in a cross-country framework over the 2002 to 2006 time period. The determinants chosen for the empirical model represent macro-economic and trade

Uppsatsen ser till vad som sker med inflationen och produktionsgapet (skillnaden mellan den faktiska produktionen och den potentiella produktionen) när en centralbank blir självständigare genom att Rogoff-konservatism införs. Första delen av uppsatsen avhandlar två modeller inom detta monetära ämne och huvudfokus ligger på den nykeynesianska modellen. Efter en redogörelse för modellens uppbyggnad

The aim of this study was to develop and psychometrically evaluate an instrument for measuring the impact from chronic pain on daily life. Traditionally psychometric evaluation is done with parametric methods even if the items are ordinal data. In this study the instrument to be developed is solely based on ordinal data, and the psychometrically evaluation is done with both traditional methods (i.

Syftet med uppsatsen är att undersöka ifall det är möjligt att genom kortsiktig agerande generera avkastning i handel med optioner. Principen är att använda teknisk analys för att avgöra ifall börskursen för enskild aktie, i detta fall Ericsson B, kommer att stiga eller sjunka. Handeln sker i Ericssonaktiens optioner då dessa på grund av hävstångseffekten kan generera större avkastning samt möjlig

The most famous theory of family economics is probably Gary Becker’s Quantity-Quality model. Assuming scarce parental resources, it predicts a negative relationship between family size and adult success. The model assumes that parents have common preferences and that income pooling takes place. However, modern theories of household allocation have shown that the assumption of common preferences is

This thesis is based on Heston and Nandi’s (2000) paper. The aim is to check how their closed-form discrete-time GARCH option pricing model performs on Swedish data, and if there are any significant changes to its performance when estimating it via maximum likelihood using the Normal- and the Student-t distribution. The model is compared with the Black-Scholes- and the ad hoc Black-Scholes model o

Denna uppsats behandlar vilka negativa konsekvenser som kan uppstå vid outsourcing av digitala tjänster i en service-oriented architecture (SOA) miljö. Uppsatsen behandlar endast negativa konsekvenser i relation till kontrollen över den information som existerar i de tjänster och i de affärsprocesser som utgörs av tjänster som outsourcas. Syftet och resultatet av uppsatsen är en punktlista som pre

This study is concerned with the statistical analysis of tick-borne encephalitis (TBE) antibody decrease after vaccination. The objective is to derive conclusions about protection duration of vaccination. TBE is a serious infection affecting the central nervous system and Austria is a high risk region of TBE. Active immunization by vaccination prevents TBE and nowadays 88% of Austria's populat

A Rothschild & Stiglitz (1976) model of a market for insurance is used in order to discuss how asymmetrical information can lead to a decrease in coverage in the market. A simple model of how an individual mandate that requires all individuals in a population to obtain insurance affects the market equilibrium is proposed. I show how such a mandate can give implications for the existence of a e

Livsmedelsbistånd har en möjlighet att ta hand om den akuta hungern hos människor medan de kan koncentrera sig på att ta sig ur fattigdomen. Trots sin lilla andel av världshandeln är det livsmedelsbiståndet som kan ha en direkt inverkan på folk beroende på sin karaktär i form av mat. Syftet med uppsatsen är att analysera vilka faktorer som påverkat livsmedelsbiståndet från Europeiska Unionen till
