Popular Abstract in Swedish I många utvecklingsländer i tropiska klimat leder den snabba urbaniseringen till många problem, bl a försämrad termisk komfort i utemiljön. Detta har negativa följder för människors hälsa och välbefinnande och påverkar sociala och kommersiella aktiviteter utomhus negativt. Följaktligen är det mycket viktigt att åstadkomma komfortabla mikroklimat i urban miljö. Den huvuIn many developing tropical countries, rapid urban growth leads to several problems, including increased thermal stress. This has negative consequences for people's health and well-being, and affects social and commercial outdoor activities negatively. Consequently, the creation of thermally comfortable microclimates in urban environments is highly important. The main aim of this thesis is to dee

The changes in force characteristics as well as the shedding patterns for various dual sphere configurations are studied. The Reynolds numbers considered are 300, 600 and two different inflow conditions are used: steady and pulsating. The sphere formations are defined by the separation distance D-0 between the spheres and the angle between the line connecting the centres of the spheres and the mai

Persistent organic pollutants (POPs) and heavy metals are well known environmental pollutants. Even though numerous studies have been carried out to assess human exposures to these compounds, there is still a lack of data on humans from developing countries, especially in underprivileged children. The objective of this study was to assess the exposure to POPs and heavy metals in children from Dhak

The biotechnology industry has grown considerably over the past twenty years, and the revolution within the field of molecular biology has dramatically improved the possibilities of producing proteins and other important biomolecules. The product of interest will be obtained in a multi-component solution and some challenging purification work has to be performed to recover the target molecule in a

Most methods that guide the designer through the later phases of the design process are general in nature, and it is up to the designer to organize the design work using the tools and techniques available. This process also relies greatly on experience, which is quite a challenge for students, who are mostly novices in the area. In a comparative study, the evolution of the experience and skills ac

Purpose – The purpose of this paper is to present findings concerning what logistics managers perceive as being difficult and challenging, and what implications this may have for further advances in the logistics discipline. Design/methodology/approach – The point of departure for this study was to reflect on perceived problems, uncertainties, trends, and solutions in logistics, and how they are h

Radiological and pathological characteristics of hip osteoarthritis (OA) is joint-space loss due to degradation of articular cartilage. However, patients with early-stage OA do not yet show any radiological signs, which leaves them without diagnosis and treatment. This study evaluates the potential of a novel tool to identify pre-radiographic OA changes based on hip bone morphology. Two statistica

Importance: CD11b + immune cells have been implicated in the formation of choroidal neovascularization in experimental studies on animals and disease-association studies on humans. However, the clinical importance of such obser

The static potentials from bosonic string models are examined to the two-loop level. Available MC data for 4-dimensional SU(3) are in approximate agreement with the universal leading order predictions but fail to reproduce the Nambu string when the two-loop terms are included in the analysis. We also confront Nambu string model predictions for Tc σ with SU(2), SU(3) and SU(N → ∞) MC data. In the S

Increasing loading of terrestrially derived dissolved organic matter tends to enhance bacterioplankton respiration (BR) in boreal estuaries, but knowledge on the mechanisms behind this effect is not complete. We determined the stable isotopic signature of the reactive estuarine dissolved organic carbon (DOC) in the Öre estuary (Baltic Sea) by using the Keeling plot method. The δ13C ratio of the es

Background: High-sensitivity assays for cardiac troponin T (hs-cTnT) are sometimes used to rapidly rule out acute myocardial infarction (AMI).Purpose: To estimate the ability of a single hs-cTnT concentration below the limit of detection (<0.005 µg/L) and a nonischemic electrocardiogram (ECG) to rule out AMI in adults presenting to the emergency department (ED) with chest pain.Data Sources: EMBASE

Wildland-urban interface (WUI) fire incidents are likely to become more severe and will affect more and more people. Given their scale and complexity, WUI incidents require a multidomain approach to assess their impact and the effectiveness of any mitigation efforts. The authors recently produced a specification for a simulation framework that quantifies evacuation performance during WUI incidents

Popular Abstract in Swedish Det så kallade Chilenska ekonomiska undret under 1980- och 1990-talet är resultatet av en omfattande strukturförändring av den Chilenska ekonomin. I denna omvandling har jordbrukets modernisering och kapitalisering spelat en mycket viktig roll.Huvudfåran i den akademiska debatten har hittills huvudsakligen förklarat omvandlingen genom tillämpning av olika policy instrumThe so-called Chilean economic miracle during the 1980s and 1990s connotes not only high-speed economic growth but also a profound structural transformation of the Chilean economy. Most previous research ascribes growth and transformation to the liberalisation of markets and other neo-liberal policy instruments introduced after 1974. Policies, before as well as after 1974, have indeed been importa

Urinary hexahydrophthalic acid (HHP acid) levels were determined in 20 workers occupationally exposed to hexahydrophthalic anhydride (HHPA) air levels of 11-220 micrograms/m3. The levels of HHP acid in urine increased rapidly during exposure and the decreases were also rapid after the end of exposure. The elimination half-time of HHP acid was 5 h, which was significantly longer than in experimenta

Background/Aim: In occupational therapy research and in clinical practice there is a need for valid, reliable and easily administered measures. For research and screening purposes, the Satisfaction with Daily Occupations (SDO) instrument was developed. It addresses work, leisure, domestic tasks and self-care and generates a satisfaction and an activity level score. This study investigated its cons

The dissertation is about management of equipment maintenance in manufacturing firms. The overall research objective is to describe how maintenance interacts with manufacturing and explain how it contributes to high performance of organisations. It reports findings from eight papers, each dealing with parts of the overall objective. The empirical data is collected from two surveys to Swedish manu

Exhaust emissions from lean burn natural gas engines may not always be as low as the potential permits, especially engines with open-loop lambda control. These engines can produce much higher emissions than a comparable diesel engine without exhaust gas aftertreatment. Even if the engine has closed-loop lambda control, emissions are often unacceptably high for future emission regulations. A three-

The search for an enzyme as a reagent for selective bioanalytical detection of the neurotoxic amino acid, beta-N-oxalyl-L-,alpha,beta-diaminopropionic acid, beta-ODAP (found in grass pea, Lathyrus sativus) led to its redox catalytic reaction by glutamate oxidase (GluOx). Homogeneous kinetic studies and an immobilized GluOx reactor-based flow-injection assay were initially made for beta-ODAP with s
