In this paper three unit root tests that allow for a break in both the seasonal mean and linear trend of the data are proposed. The tests, which can be seen as smallsample corrected versions of already known asymptotic tests, are shown to perform very well in simulations, and much better than their asymptotic counterparts.
The feasibility of anaerobic treatment of methanol condensate from pulp and paper mill in UASB reactor was investigated and compared with the anaerobic treatment of methanol. The UASB reactor treating methanol condensate was operated for 480days with minimum problems of overload. COD removal from methanol condensate and methanol under normal operating conditions ranged from 84-86% to 86-98%, respe
In the present work, near-limiting hydrogen flames were investigated both experimentally and numerically. Very rich hydrogen + air flames were studied in a constant volume bomb equipped with a pressure sensor and a Schlieren system for optical registration of the flame front movement. The mixtures contained 70% and 75% of hydrogen, the rest being air. The measurements were conducted at pressures f
Background: This study investigates responses to requests for clarification in conversations between children/adolescents with cochlear implant (CI) and normally hearing peers. Earlier studies have interpreted a more frequent use of requests of confirmation (yes/no interrogatives) in the CI group as a conversational strategy used to prevent communication breakdowns and control the development of t
Differences in ecological conditions can result in the evolution of dramatic inter-population shifts in whole suites of traits. We studied variation in reproductive output in three lizard populations of the Skyros Wall Lizard (Podarcis gaigeae, Lacertidae) endemic to the Skyros Archipelago (Greece), which live under similar climatic conditions but differ in predation pressure and food availability
In discussions of moral responsibility for collectively produced effects, it is not uncommon to assume that we have to abandon the view that causal involvement is a necessary condition for individual co-responsibility. In general, considerations of cases where there is "a mismatch between the wrong a group commits and the apparent causal contributions for which we can hold individuals responsible"
Popular Abstract in Swedish För firande av mässa i den katolska kyrkan krävs ett altare av sten. Altaret ska invigas av en biskop enligt en viss ritual. Ett viktigt element i altarinvigningsritualen är placeringen av reliker i altarets inre. Före reformationen på 1500-talet gällde denna regel även i Norden. Trots altarnas centrala betydelse i den medeltida nordiska kyrkan har de ägnats liten uppmäThis dissertation deals with the subject of altars in the churches of the medieval diocese of Lund. The main work on altars in the Catholic church is Joseph Braun´s Der christliche Altar in seiner geschichtlichen Entwicklung (1924). However, despite its extensive content it does not deal with the conditions in Northern Europe. The general aim of this dissertation is to broaden our knowledge about
Single top quark production via four-fermion contact interactions associated to flavour-changing neutral currents was searched for in data taken by the DELPHI detector at LEP2. The data were accumulated at centre-of-mass energies ranging from 189 to 209 GeV, with an integrated luminosity of 598.1 pb(-1). No evidence for a signal was found. Limits on the energy scale Lambda, were set for scalar-, v
A cohort of 1,220 farmers, 1,130 nonfarming rural men, and 1,087 urban referents from Sweden were monitored for 12 years. Farmers had lower mortality than urban referents for all causes of death (hazard ratio [HR] = 0.51; 95% confidence interval [CI], 0.37-0.71), cancer (HR = 0.44; 95% CI, 0.24-0.78) and cardiovascular diseases (HR = 0.60; 95% CI, 0.36-0.99). Nonfarming rural men had lower mortali
Objective. Patients with hepatitis C have been shown to have impaired health-related quality of life (HRQoL). The aim of this study was to determine HRQoL in patients in different stages of hepatitis C virus (HCV) and to compare HRQoL in HCV cirrhosis with non-HCV-induced cirrhosis. Material and methods. Out of 489 consecutive patients who fulfilled the inclusion criteria, 472 (96%) agreed to part
Robust and reliable formulas for predicting bed load and suspended load were developed for application in the nearshore zone where waves and currents may transport sediment separately or in combination. Also, a routine was included to determine the sediment transport in the swash zone, both in the longshore and cross-shore directions. An important objective of the development was to arrive at gene
Popular Abstract in Swedish I denna avhandling undersöks argumentationsstrategier för att legitimera eller delegitimera en sak eller person i Sveriges tidiga politiska debatt i pamfletter. Det empiriska syftet med är att undersöka det politiska språket i den framväxande politiska offentligheten, med fokus på år 1769 och 1809-1810. Det teoretiska och metodologiska syftet är att diskutera vilket slaThis thesis discusses argumentative strategies for legitimation and delegitimation in political pamphlets published in 1769 and in 1809–1810, each period representing the onset of democracy and freedom of the press. The aim of the study is twofold. The empirical aim is to examine the political language in the early political debate in pamphlets, with a focus on how the discursive strategies of leg
This article examines ways of constructing research questions from existing literature, which are likely to promote the development of interesting and influential theories. We review 52 articles in organization studies and develop a typology of how researchers construct their research questions from existing literature. The most common way across paradigmatic camps is to spot various 'gaps' in the
Background: Epidemiologic evidence of an association between fish intake and type 2 diabetes (T2D) is inconsistent and unresolved. Objective: The objective was to examine the association between total and type of fish intake and T2D in 8 European countries. Design: This was a case-cohort study, nested within the European Prospective Investigation into Cancer and Nutrition (EPIC) study, with 3.99 m
Abstract in Undetermined De arkeologiska, medicinhistoriska och etnografiska källorna visar att trepanationer är ett univer- sellt fenomen, men också intimt kulturspecifikt i sitt syfte och i sin handling. Denna operationskonst visar att personer klarat de påfrestningar ett sådant ingrepp medfört, och att kunskapen om hälsa och ohälsa inte varit främmande i de mest skilda kulturella sammanhang. De
A fully instrumented slice of the ATLAS detector was exposed to test beams from the SPS (Super Proton Synchrotron) at CERN in 2004. In this paper, the results of the measurements of the response of the barrel calorimeter to hadrons with energies in the range 20-350 GeV and beam impact points and angles corresponding to pseudo-rapidity values in the range 0.2-0.65 are reported. The results are comp
This article examines how ordinary Russian and Ukrainian citizens experience and relate to extensive and pervasive corruption (high- level, everyday, political) in everyday discussions and demands – in relation to authorities, politicians, civil servants, and fellow citizens. Anonymous interviews conducted in Ukraine and Kaliningrad oblast from 2009 to 2014 show differences in anti-corruption dema
