Sverige är för tillfället operativa med Helikopter 16 - Black Hawk i Afghanistan. Uppgiften som löses i Afghanistan är främre och taktisk sjuktransport (MEDEVAC).Detta arbete handlar om hur befintliga VMS-system i helikoptrar kan kompletteras i syfte att möta ett föreliggande prickskyttehot vid lösande av främre MEDEVAC i ett insatsområde som miljömässigt liknar Afghanistan. I arbetet analyseras möjliga tekniker utifrån aspekter från ett konstruerat scenario där helikopterbesättningarnas uppgift, insatsmiljö samt hotbild beskrivs.Resultatet visar på att MEDEVAC-helikoptrar kan utrustas med sensor-gimbaler där olika sensorer kan kombineras, vilket möjliggör spaning i 360°. Detta bidrar till den militära nyttan då helikopterpersonalens lösande av uppgift effektiviseras, chansen till överlevnad ökar samtidigt som personal och patienter kan känna sig tryggare..

Gravitational lenses are unlike ordinary optical lenses, a phenomenon corrupting our optical view of the cosmos. When we look out intospace we see celestial bodies lying with astronomical distance from Earth. There is no guarantee that what we see out there in space is actually there where we are observing it, and it may be that we see multiple images of the same star! Studies have shown that thenumber of distorted images of an n-mass (n > 1) plane lens can not exceed 5(n -1) for lighter lenses or 5n for more massive lens. This mathematical thesis covers gravitational lensing and their properties that distort light rays coming towards us from distant celestial bodies. In addition of gravitational lensing, its properties and the proof of the maximum number of distorted images, a bigger part of this work even cover two very interesting mathematical tools - the so-called Schwarz function and Bezout theorem..

Swedish agriculture has gone through big changes in the latest 60 years. The farm sizes have increased, which has led to raised tractor and machinery sizes and therefore increasing problems with soil compaction. A method to reduce these problems is to implement controlled traffic farming, CTF. All field operations are then concentrated to specific tracks by using GPS guidance. The aim of this work was to study how the tillage regime, with or without CTF, affects the soil, with the main focus on macroporosity. In Säby close to Uppsala, and Alnarp close to Malmö, randomized block trials has been carried out, and the data has mainly been taken from these trials.

Röntgenläkarna väljer ofta att byta undersökningsteknik för att fastställa misstänkt patologi som inte går att diagnostisera med en metod. Vid röntgenundersökningar av sinus (bihålor) så kan läkaren välja mellan konventionell röntgen eller en datortomografiundersökning. Skälet är att diagnoser som tumör, benpåverkan eller ansiktstrauma inte avbildas lika bra med den konventionella metoden. Syftet med den här studien är att jämföra datotomografi och konventionell röntgen vid sinusundersökningar, vilka för och nackdelar som de olika metoderna har, hur bildinformationen och diagnostiken skiljer sig, vilka risker som finns med joniserad strålning samt vilka biologiska effekter strålningen har på människan. Intervju har gjorts med odontologi läkare som berättat om för och nackdelar med de olika metoderna, och litteratur och artiklar har gett kunskap för att komma fram till resultatet.

Denna rapport beskriver ett examensarbete där optiska fibrer av plast integrerades i varpled i en väv. Syftet med examensarbetet var att undersöka om det är möjligt att industriellt producera ljusemitterande vävar med optiska fibrer. Arbetet delades upp i olika delar, både teoretiska och praktiska. Den teoretiska delen innebar informationssökning inom olika medier, såsom vetenskapliga artiklar och intervjuer med insatta människor inom de berörda områdena. Den praktiska delen i examensarbetet bestod av flera olika moment.

The mining company LKAB extracts iron ore in three areas in the north of Sweden, Kiruna, Malmberget and Svappavaara. The iron ore is refined and in the pelletizing plants the material is rolled to finished pellet product. The different steps of pelletizing plants causes among other things emissions to the air. It occurs occasionally stops in the production and the emissions are vented via an emergency chimney without purification. The aim for this work is to look into how LKAB may improve their monitoring of air emissions and control of ambient air quality and the analysis methods which are suitable for measuring.

Background: Daily news reports of school violence, bullying and harassment are common. The school has developed into an arena which has been exposed into a growing unhealthyness. Paradoxically, financial resources decreases while demands on school staff increases. How does school staff and personal cope with these demands? Aim: We sought to study sense of coherence among school employees in two schools; a comparison between one health promotional school and one school in the process of working with health promotion.

The purpose of our paper was to understand the motivators that kept the social workers within the profession. Social workers' have a profession that, to the greatest extent, means high working load and difficult problematic issues. On the basis of this starting point we asked us why so many social workers still choose to remain within the profession for several years. The purpose of our paper is to understand what motivates the social workers to stay within their profession. To understand which are the motivators, we decided to use the theory salutogeent perspective with Aaron Antonvsky's sense of coherence.

Sense of coherence amongst employees with reduced work-capacity at Samhall.Sanela Jakupovic TrostekScientific essay in public health, 15 hp, Academy of Health and promoting Working Life, University of GävleThe aim of this study was to examine how employees at Samhall who has reduced work-capacity experienced their sense of coherence (SOC). The study includes gender, age and civil status in the analysis. The study includes 34 respondents which are divided as 20 men and 14 women. To measure SOC a quantitative method with a 29 standardized questionnaire was used.It was found that the employees felt, in general, low SOC, which means more difficult adaptation to their life situation. Noteworthy is that 70 % of the men in this study showed low SOC compared to 35,7 % of the women.One conclusion that can be drawn is that within Samhall, it showed that women had a higher SOC mean value than men which means they are more equipped to handle, understand and find meaning in their work life. Keywords: Antonovsky, Samhall, disability, work-capacity, sense of coherence (SOC).

The study is a case study of an activity, called the Oliven, that provides practice for people who are in the Arbetsförmedlingens Job- and development guarantee. The purpose of this study was to examine what it is in the Olivens activities, for people who are part of Phase 2 and 3 of the Job- and development guarantee, which, according to the participants, are working well and what works less well. We wanted to study how the participants perceive their work situation during the time that they participate in the activities. That is to gain knowledge of how the activities for people who are looking for work can be designed so that the participants can, from a salutogenic perspective, create a sense of coherence while they are participating.We have collected the empirical data through participant-observation and semi-structured interviews during two days. The analysis was made using the concepts ofcomprehensibility, manageability and meaningfulness.

The aim of this thesis is to see if there are differences in how managers and other staff looks at goals for short-term accommodation. The results show that there is a difference in views on the goals. This is manifested, among other things, in the form of managers have their focus concentrated on the financial framework for the business. Other staff have their focus directed at targets that are more about the work of the resident. The theory that the survey is based on is The sense of coherence and its three pillars: comprehensibility, manageability and meaningfulness..

We set out to compare two different categories of workers: the, so called, white- and blue collar workers. The studies aim was to measure if there were any observable differences between the two in means of optimism and sense of coherence. There are two tools created for measuring optimism and sense of coherence, the Life Orientation Test ? Revised (LOT-R) measures an individual?s level of optimism and Aaron Antonovsky devised a test for measuring an individual?s level of sense of coherence (SOC). Optimism is best explained like a way to measure anticipation, how an individual expect future events to fall out.

Nanotechnology, one of the most interesting sciences today will no doubt have an enourmous impact on tomorrow's society and industry. One of the most interesting nanomaterial that has been discovered is the semiconductor quantum dot (QD). This material shows interesting novel properties such as a size-dependent band gap, which is an effect caused by the quantum confinement effect in all three dimensions. Due to this phenomenon the absorption spectrum can be tuned to the desired value by adjusting the size of the QD.This thesis aims to investigate how the solvent ratio of H2O/Ethanol affects the optical and structural properties of copper sulfide QDs manufactured in a chemical synthesis way using modern microwave heating. The process of manufacturing QDs using chemical synthesis often involve a capping-agent to prevent the QDs from agglomerate into bigger structures.

Background: Physical activity is important to sustain your health, but there are also other factors which can influence health. One of them is the degree of sense of coherence. Aim: The main purpose of this study was to examine if there existed a correlation between amount of physical activity and degree of sense of coherence (SOC) in adolescents in the northern parts of Sweden. This study also dealt with differences and similarities between and within the whole examination- group and subgroups. Methods: A SOC- questionnaire with 29 items, developed by Antonovsky, was used.

Purpose: Our aim is to get an insight on how home care workers experience, handle and looks upon their work. We also want to form an opinion of how home care workers experience the relationship to the clients they meet.Questions: How does home care workers experience their daily work with their clients? Home care workers daily meet many different sorts of clients with different needs, how do they handle this? What kind of support does home care workers get in their work?Method: A qualitative design with semistructured interviews.Conclusion: The most central conclusion from all of our interviews were: that home care service workers has a very stressful and demanding occupation, that the work has a low status, that the personnel has a big responsibility for the wellbeing of other people and that they often find their work satisfying and fun. To have someone to talk to and exchange ideas with was also mentioned by the informants as a vital part of feeling support in their work. From the Antonovskys theory, a sense of coherence, and Goffmans views of the society, we also find that the larger part of our informants feel a high sense of coherence and that when they have to adjust to their different caretakers they play different roles..
