One feature of climate change is the increasing heat exposure in many workplaces where efficient cooling systems cannot be applied. Excessive heat exposure is a particular problem for working people because of the internal heat production when muscle work is carried out. The physiological basis for severe heat stroke, other clinical effects, and heat exhaustion is well known. One feature of this h
In Safeguards work under the Non-Proliferation Treaty, the isotopic analysis of uranium and plutonium micro particles has strengthened the means for detecting undeclared nuclear activities. In order to assure accuracy and precision in the analytical methodologies used, the instrumental techniques need to be calibrated. The objective of this study was to produce and characterize particles consistin
With the attempts to increase power, efficiency and thrust, modern gas turbines operate with combustor outlet temperatures of 1800-2000 K, which are far beyond the allowable metal temperatures. Turbine blades are exposed to these 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 importan
Large-eddy simulations (LES) coupled with a partially-stirred reactor model and a finite-rate chemistry are carried out to investigate the effects of n-heptane injection timing on the methanol fueled dual-fuel (DF) combustion. Methanol is premixed with air in a constant volume chamber (T=1000 K, ρ=14.8 kg/m3) to form a homogeneous mixture (equivalence ratio ϕm of 0.3). Liquid fuel n-heptane is pro
Spectral information obtained from induced polarization (IP) measurements can be used in a variety of applications and is often gathered in frequency domain (FD) at the laboratory scale. In contrast, field IP measurements are mostly done in time domain (TD). Theoretically, the spectral content from both domains should be similar. In practice, they are often different, mainly due to instrumental res
This paper reports on the spray structure of the biofuels, ethanol, and butanol generated by a multihole direct-injection spark-ignition injector, which is studied in a constant volume chamber. The spray shape and structure are analyzed using two-phase structured laser illumination planar imaging where both laser-induced fluorescence and Mie-scattering light are recorded simultaneously for the ext
Nitric oxide (NO) acts as a modulator of neuronal transmission in mature neuronal systems, including the retina. Recently, NO has also been suggested to have a trophic function during development. We examined immunocytochemically the distribution of NO-producing cells in developing and transplanted rabbit retinas. An antibody detecting the neuronal isoform of its biosynthetic enzyme, nitric oxide
The aim of this study is to understand the mechanisms behind the diffusion of fired bricks in Hellenistic Europe, initiated in the north Aegean in the 4th century BC. To this end, a social diffusion model is used to simulate the available archaeological data pertaining to this process. The starting point in the construction of the model is the assumption that different categories of people contrib
A procedure for evaluating depletion of snow covered area (SCA) using mean air temperature has been outlined and tested. Because depletion of snow is a cumulative effect of climatic conditions in and around snow cover area, the cumulative mean temperature (CTM) at a nearby station should represent depletion of SCA. The study was carried out for Satluj basin (22,305 km(2)) located in the western Hi
Aim: This paper describes the quality assurance (QA) work performed in the Swedish multicenter ARTSCAN (Accelerated RadioTherapy of Squamous cell CArcinomas in the head and Neck) trial to guarantee high quality in a multicenter study which involved modern radiotherapy such as 3DCRT or IMRT. Materials and methods: The study was closed in June 2006 with 750 randomised patients. Radiation therapy-rel
Objective. Patients with RA have an increased risk of cardiovascular disease. Management of RA has changed substantially over time. Our aim was to evaluate changes in cardiovascular morbidity and mortality over the period of 1978-2002. Methods. Two cohorts of consecutive patients with RA seen at outpatient clinics in Malmö, Sweden, were started in 1978 (n = 148) and 1995 (n = 161) and compared wit
Monte Carlo (MC) simulations are the standard tool for describing jet-like multi-particle final states. To apply them to the simulation of medium-modified jets in heavy ion collisions, a probabilistic implementation of medium-induced quantum interference effects is needed. Here, we analyze in detail how the quantum interference effects included in the Baier-Dokshitzer-Mueller-Peigné-Schiff–Zakharo
Epilepsy is a neurological disorder characterized by its debilitating epileptic seizures. There are generalized seizures, which affect the whole brain at once, and focal seizures, which start from one part of the brain. The most common focal epilepsy, is temporal lobe epilepsy representing almost 70% of all focal epilepsies. Around 30% of all patients are therapy refractory, therefore there is a h
Objective. This study aimed to survey current Swedish practices for performing and handling transrectal ultrasound-guided prostate biopsies. Material and methods. A Swedish Urology Network (SUNe) was organized for the distribution of information, survey studies and research collaborations. A web-based questionnaire was distributed to the members in 2011. Results. In this first SUNe survey, 137 (91
The forceful storms and the stricter regulations from the government within the last years have forced E.ON to start a project called “Krafttag”. The goal of the project is to ensure uninterrupted power supply to the customers by investing in underground cables. A problem with the underground cables is the high natural capacitance that contributes to an enlarged current in the case of an earth fau
Context: The impact of long-term GH replacement on cerebrovascular and cardiovascular diseases and diabetes mellitus in hypopituitary patients is unknown. Objective: The incidence of nonfatal stroke and cardiac events, and prevalence of type 2 diabetes mellitus ( T2D) and cardioprotective medication were compared between cohorts of GH-deficient (GHD) patients and population controls. Design and Pa
Antalet nyanlända personer i Sverige har ökat dramatiskt de senaste åren. Ansvaret för dessa människors boende är både en statlig och en kommunal angelägenhet. Denna uppsats undersöker ansvarsfördelningen och hur långt rätten till bostad sträcker sig i svensk lagstiftning. Uppsatsen undersöker om rätten till bostad åtnjuts på lika villkor av alla människor som lagligen uppehåller sig i Sverige. DeIn the last years, there has been a largely increased number of refugees in Sweden. The responsibility for these peoples’ living situation are both a responsibility for the state and for the municipalities. Thus, this paper will examine the distribution of responsibility and how far the right to housing extends in Swedish national law. This paper focus on the subject if the right to housing is enj

Being a small business in the clothing industry involves a lot of hard work that extends beyond the usual eight-hour day. It is an industry characterized by fierce competition, tough conditions and requires cutting costs, unique marketing and a strong brand to succeed. However, this is everyday life for Svensson Jeans, a young clothing company that since its inception five years ago sells its own
Inlåsta med avfall ...? HERVÉ CORVELLEC & ANETTE SVINGSTEDT | LUNDS UNIVERSITET EU har beslutat om en “avfallstrappa” – som handlar om att vi i första hand ska förebygga avfall. Går inte det är det återbruk som gäller, därefter återvinning av materialet. I sista hand bör avfallet eldas upp för energiåtervinning eller läggas på deponier. Men frågan är hur vi når till det högsta steget i avfallstrap
