This work aims to obtain information on diurnal variations of aerosol concentrations in thecity of Lund (Sweden) and trying to locate the origin of the aerosols long distance transports.The study shows that the aerosol concentrations varied quit strongly over the entiremeasurement period, reflecting air masses of different degrees of pollution, mainly as a resultof the diurnal rhythm of the traffics. Trajectories reveals that air masses originated inSoutheastern and Eastern Europe contains higher aerosol concentrations compared to other airmasses..

ABSTRACTBackground: Most cases of lumbar disc herniation are asymptomatic. When symptomatic, LDH may cause a significant physical and mental distress. Initially, most patients are treated conservative but sometimes operations may be required.Aim: The aim of this study was to provide a review of the scientific basis of physiotherapy, including behavioural therapy, as a treatment to lumbar disc herniation regarding pain, function and the size of disc herniation in people suffering from lumbar disc herniation.Method: Four databases were used in the searches of literature. Assessment of the validity of the studies was done with the PEDro-scale and valuation of evidence rate was made according to guidelines made by the Swedish Council on Health Technology Assessment (SBU).Result: Nine RCT-studies were included with a total of 713 participants. The scientific basis is moderate to support a pain reduction and limited regarding improvement of physical function when it comes to physical exercises, including MDT.

Aim and questionsThe purpose for this study was to investigate how marks and mark settings are formed in physical training at some compulsory schools. We also wanted to see how the criteria for marks are formed. These were the main questions during this study.? How do the students find the evaluation and the making in physical training?? Are there differences between different student groups when it comes to their experience around estimation and marking in physical training? (gender, marks, schools etc.)? How do the teachers motivate their marking in physical training?? Are there any differences between the criteria for marking between different schools?MethodThe study was carried out during the spring 2005 at eight schools in a municipality in the middle of Sweden. The study involved 339 students opinion polls and 12 teacher opinion polls.

BACKGROUND: The relationship between physical activity and health versusphysical inactivity and poor health are well known. Ethnic minorities are generallyless physically active than the residence country's majority population andgenerally have a poorer health status. The study has a health promotion perspective.PURPOSE: The purpose of this study was to describe factors that influencephysical activity among middle-aged and older persons, belonging to an ethnicminority. METHOD: The method used to answer the purpose is a literature-basedstudy. The searching for literature has been carried out in a systematic way.Scientific articles to base the results on, has been gathered from various databases.Included articles were analyzed with a qualitative content analysis and identifiedsimilarities and differences in the content were divided into themes and categories.RESULTS: Recurrent themes in the literature, that influence physical activity inmiddle-aged and older people that belong to an ethnic minority, was support, healthand illness, external factors, internal factors, community related and socioeconomicfactors and ignorance and beliefs.

This paper examines the power producing dams along the Ume-river as an integral part of and a result from the urbanization process in Sweden during industrial capitalism. The aim of the paper is to contribute to the knowledge of the urbanization process in Sweden in general and of its traces along the Ume river in the county of Västerbotten in particular. The paper applies the theory of concentrated urbanization and extended urbanization put forward by Neil Brenner and Christian Schmid (2015) and argues that the building of power producing dams along the Ume-river is part of an extended urbanization process. This becomes particularly evident when examining the vast physical structures that is the dams, situated in an otherwise remote and sparsely populated area. These vast physical structures are also very well connected to a nation wide electric grid that has connections to bordering countries as well.

Development in spin dynamic occurs in the whole world because of therising demands on fast electronic storage for example hard drivesand RAM (Random Access Memory). Measuring the spin resonance of amaterial gives you the insight of the theoretical speed for amagnetic memory. This means the maximum storage speed is below thefirst resonance. All magnetic materials have different propertiesthat will inflict the resonance frequency which brings that theconstructors of memories need to know which magnetic material theywill use to obtain best results. In the market for normal users themaximum storage speed in a RAM memory is 1.6 GHz.

Larmrapporterna om barns övervikt blir allt fler, det har blivit ett stort hälsoproblem i såväl Sverige som i resten av västvärlden. Ett sätt att få barn, både överviktiga och icke överviktiga, att bli mer aktiva är att engagera dem på lektionerna i idrott och hälsa i skolan. Syftet med denna studie var att ta reda på om det sker något förebyggande arbete för de eleverna med övervikt, på idrottslektionerna. Data samlades in genom att skicka ut enkäter till rektorer, på grundskolor i Skåne, med uppmaning att de skulle vidarebefordra enkäten till idrottslärarna i år 3 och år 5. Sammanlagt deltog 57 idrottslärare i studien.

Choir singing is one of the most popular national movements in Sweden but the knowledge of the meaning of this activity for health and well being from the choir singers? own experiences is limited. The purpose of this study was therefore to develop useful knowledge about the meaning of choir singing for participating persons from a health perspective. The data was collected through qualitative interviews with six different choir singers and went after that through a comprehensive analysis which resulted in four main categories: an oasis in the existence; possibilities of meetings and solidarity; goals and musical development; and physical and emotional well-being. The results showed that the choir activity represents a place where the singers can escape the demands and the stress factors of everyday life and where they get the opportunity of meaningful relations with other people.

Every year begomovirus infections cause severe constraints to the tomato production in Nicaragua. Extensive yield losses are followed by large economical losses, both for the country and the single farmer. During recent years the use of begomovirus resistant or tolerant tomato cultivars has increased in Nicaragua as an effort to improve yields. Still, begomovirus infection is a large threat to the tomato production. Therefore, ongoing work in Nicaragua is focusing on finding new, better, begomovirus tolerant or resistant tomato cultivars.

The purpose of this study was to investigate the association between physical activity and perceived stress, energy and musculoskeletal disorders among office-workers and warehouse-workers and also to see if there were any differences depending on work-place and gender. The method that was used to collect data was three different validated questionnaires that measured stress and energy (the Stress-Energy questionnaire), musculoskeletal disorders (intensity and localization of pain, a Pain Drawing questionnaire with a VAS-scale) and physical activity (IPAQ ? the short version). Eighty-eight workers participated in the study. Forty-seven of them were office-workers and forty-one were warehouse-workers.

If one looks at physical planning in Sweden today one can see that while talking about densification of existing development, reduced emissions and careful use of important land, urban sprawl is a fact with development of sheer residential districts in the urban edges and shopping malls in each and every municipality. As sustainable development is an essential goal for physical planning to strive towards, it is worth questioning if the direction of today?s planning will lead to the goal. A sustainable development can be seen as an obvious to goal aim at. In reality the aim means a hard and complex work.

In Uppsala CHP Plant, there are six pressure reducing valves to reduce the pressure from 15 to 3 bars, before six absorption heat pumps. During the process the energy is conserved but losses occur in form of exergy. The aim of this thesis is to reduce the losses of exergy. This can be done by letting turbines replace the pressure reducing valves.In this thesis an investigation has been done of the conditions today, the conditions after the change from pressure reducing valves to turbines and a comparison of three different types of turbine solutions. The three examined solutions are one turbine, several helical screw expanders and several small turbines in parallel with asynchronous generators.The six absorption heat pumps have been divided into two groups; one group of four and one group of two absorption heat pumps.

Introduction: In the past years children in primary school age has become increasingly sedentary. One of the school nurses' main task is to provide tools for students to make healthy choices. During the health visit, the school nurse gets the opportunity to inform and talk about health and physical activity with the students.Aim: To describe how shool nurses? work to motivate students to physical activity.Methods: The authors have conducted a pilot study that will form the basis for a large-scale study. Four nurses were interviewed using an interview guide based on open-ended questions and a qualitative content analysis was used when the interviews were analyzed.Results: The analysis revealed two categories and four subcategories.

Abstract:Ambulance nurses have in their everyday work a varied work environment, the pace of work can quickly shift from being calm and structured to be a severe acute situation.Objective: The aim of the study was to describe how professional nurses in the ambulance operations experience their physical and mental work environment in daily practice.Method: A qualitative interview study with semi structured questions was used. The study group consisted of two women and three men, ages between 27?42 years. The study was carried out on an ambulance station in central Sweden. Based on collected data, a qualitativecontent analysis was performed that resulted in three categories.Results: The result showed that the ambulance nurses regarded that it was a lot of heavy lifting.

The thesis was done in collaboration with EAB situated in Smålandsstenar. In the initial discussion faze on doing a thesis with them there was a need to analyze and ensure the strength of an existing product, cantilever racks. This included performing FEM calculations on a model and comparing the results with physical tests.EAB has two models of cantilever racks, a light duty and a heavy duty. Within the heavy duty model series there are five product variants that differ in both size and load capacity. We will be working with the product variant with a load capacity of 1000 kg/arm which is the variant that is in the middle of the series.When we started work on the thesis we did a literature study and couldn?t find any well defined methodology that integrates both product development and computer aided design analysis.
