Objective . Salivary cortisol is widely used in occupational health research. However, many ordinary daily activities can influence the concentrations of cortisol and the interpretation of field studies. The aim of the present study was to evaluate the effect of lifestyle factors on salivary cortisol in everyday settings. Material and methods . Healthy employees participated in one or more sub-stu
A "complex salt" of cetyltrimethylammonium (CTA(+)) with short (30 repeating units) polyacrylate (PA(-)) counterions has been synthesized. The phase diagrams of its aqueous mixtures with either the surfactant cetyltrimethylammonium acetate (CTAAc), or the polyelectrolyte NaPA, have been studied by visual inspection through crossed polarizers and by small-angle X-ray scattering. Both of the ternary
For linear time-invariant systems Bode's sensitivity integral is a well-known formula that quantifies some of thelimitations in feedback control. In this paper we show that a very similar formula holds for linear time-periodicsystems. We use the infinite-dimensional frequency-response operator called the harmonic transfer function to prove the result. It is shown that the harmonic transfer functio
Bit-error rate measurements for ON-OFF keying modulation at multigigabit per second rates over a V-band wireless link are presented. Serial data-rates from 2.5 to 20 Gb/s were studied for a 231-1 bit random sequence. Error-free data transfer over a 0.3-m link was achieved at up to 10 Gb/s. Acceptable bit-error rates, <10-5 and 10-3, were measured at up to 1.5 m for 10- and 15-Gb/s data-rate, respe
Pelagic seabirds are exposed to an array of potential threats during the non-breeding period, and effective management of these threats on a large scale requires knowledge of which populations winter where. Thick-billed murres (Uria lomvia) are emblematic of this conservation challenge, since they breed widely in the circumpolar Arctic, with many declining populations in the Atlantic. Threats faci
Background: Genital Chlamydia trachomatis (C.trachomatis) infection may lead to pregnancy complications such as miscarriage, preterm labour, low birthweight, preterm rupture of membranes, increased perinatal mortality, postpartum endometritis, chlamydial conjunctivitis and C.trachomatis pneumonia.This review supersedes a previous review on this topic. Objectives: To establish the most efficacious
Background: Whether surgeons perform better utilising a robot-assisted laparoscopic technique compared with an open approach during prostate cancer surgery is debatable. Objective: To report erectile function and early oncologic outcomes for both surgical modalities, stratified by prostate cancer risk grouping. Design, setting, and participants: In a prospective nonrandomised trial, we recruited 2
Background: Around 1015% of women suffer from depressive illness during pregnancy or the first year postpartum. Depression during pregnancy constitutes a risk for prenatal stress and preterm birth. No validated screening instrument for detecting depression during pregnancy was available in Swedish. Aims: We aimed to validate the Edinburgh Postnatal Depression Scale (EPDS) against DSM-IV criteria f
På senare tid har ett antal svenska företag inlett företagsrekonstruktion enligt det amerikanska rekonstruktionsförfarandet Chapter 11. Chapter 11 beskrivs som världsledande och har fungerat som förebild vid utformningen av i insolvenslagstiftning i flera jurisdiktioner. Chapter 11 betraktas generellt som mer gäldenärsvänligt än motsvarande förfaranden i andra jurisdiktioner. Det faktum att svenskRecently, several Swedish companies have initiated corporate reorganization under Chapter 11 of the U.S. Bankruptcy Code. Chapter 11 is widely recognized as a leading framework for corporate restructing and has served as a model for insolvency legislation in numerous jurisdictions. It is generally regarded as more debtor-friendly than comparable procedures in other legal systems. The fact that Swe
There are countless amount of questions about online learning today, this dissertation meant to extensively address two of them: the importance of control over learning pace and synchronous social learning – in other words – interactivity. Placing online learning in the context of the current participatory media landscape serves with understanding why people engage and participate and how these mo
Branding är en stor business i dagens affärsvärld. Termen används för att beskriva ett företags varumärkeskapitalsuppbyggande åtgärder. Det varumärkeskapital som byggs upp via brandingåtgärder utgör numera ofta en av ett företags mest betydande tillgångar. En tillgänglig möjlighet för näringsidkare att skydda sitt varumärkeskapital är genom generalklausulen i 5-6 §§ Marknadsföringslagen (MFL) som Branding is a big business in todays corporate world and the term is used to describe the work that is done in order to build strong brands. The brand equity that is built by branding often constitutes one of a traders most valuable assets. One possible option for traders to protect their brand equity is through the general clause in 5-6 §§ MFL in which it is stipulated that all marketing actions
Asylrätten är en het politisk fråga i och med den europeiska flyktingkrisen. Denna uppsats är ett försök att reda ut vilka folkrättsliga skyldigheter och EU-rättsliga som åligger Europeiska stater, och i synnerhet Sverige, på asylrättens område. Fyndet är att en allmän rätt till asyl inte existerar, men i praktiken finns något som kan liknas vid detta i och med förbudet mot att förvisa en flykting
