Tidigare forskning har visat att svenska stridspiloter har uppvisat en anmärkningsvärt hög förekomst av depressions- och ångestsymptom, vilket både riskerar att minska effektiviteten hos de svenska luftstridskrafterna och kan innebära en fara för flygsäkerheten.Detta arbete syftar till att underlätta beslutsfattandet kring problemet genom att skapa ett bättre underlag för att förstå de bakomliggande orsakerna. Studien undersöker när under karriären symptomen uppkommer samt jämför mellan olika pilotkategorier för att skapa en bättre förståelse för hur problemen uppstår och därmed vilka åtgärder som kan vidtas för att förhindra detta.En kvantitativ enkätundersökning användes för att undersöka förekomsten av depressions- och ångestsymptom bland svenska strids-, transport- och helikopterpiloter under deras första fem utbildningsår. Enkäten baserades på HADS-skalan och skickades till 158 personer, varav hälften var piloter.Resultatet av studien indikerar att den höga förekomsten av depressions- och ångestsymptom uppkommer senare i stridspilotkarriären. Stridspiloterna uppvisade dessutom en lägre förekomst av depressions- och ångestsymptom än en icke-flygande kontrollgrupp. Dessa resultat pekar i sin tur mot att miljöfaktorerna spelar en större roll än de genetiska faktorerna vid uppkomsten av symptomen.

The world we live in becomes more globalized as a result of new communication media. Communication occurs over greater distances which leads to increased travel. In the report AR5, by IPCC, it is showed that the human impact of climate change is clear and that something has to be done. Therefore its very important to change the human impact. A part of it is to change the way we travel within the service which leads to the purpose of the thesis.

AbstractAim: The aim of this study was to investigate if treatment with ?dry needling? in myofascial triggerpoints (MTrPs) in the rotatorcuff muscles may affect impingement symptoms such as pain during provocative tests, shoulder mobility, and function. The research questions were: Does the value of pain change on the Visual Analog Pain Scale (VAS) between before and after treatment? Do the positive provocative tests for impingement change between before and after treatment? Does the active shoulder mobility change between before and after treatment? Does the self-rated function change between before and after treatment?Method: The study was a prospective randomized intervention study and 19 persons with impingement symptoms (mean ± standard deviation; 58 ± 18 years, and shoulder pain duration 3.9 ± 1.6 months) were randomized into two groups. The groups were tested before, directly after and 3 weeks after treatment.

The first of May 2007, a decision from the Swedish Board of Fisheries about a Swedish prohibition of eel fishery got legal force. This prohibition is one of the most challenged decisions that the Swedish Board of Fisheries has taken. In the town Karlskrona in the southeastern part of Sweden the prohibition has got a lot of attention in local media. Early in the debate, it was clear that the actors active in the archipelago of Karlskrona were against the prohibition. The aim with the master thesis is to investigate different actors' opinions and view of the prohibition of eel fishery, today's management of the resource and how the actors' think that the communication between the actors involved in the management of eel and eel fishery works and what need to be changed to be able to develop a sustainable management of the eel in the future.

We would like to gain a more in depth knowledge of whether the modern orientations both within corporate governance and control philosophy lay the foundation for enterprises? more sustainable success. These both modern orientations are increasingly focusing on the importance of enterprises? setting of goals and visions on the basis of stake holders? interests and the employees? more active engagement in and motivation for the goal achievement. Despite these common inherent characteristics, it is not evident from current scientific debate how such integration actually emerges in the control philosophies of the enterprises.

This essay aims to examine how three active history teachers in the upper secondary school interprets the new course plan for history in gy11. The essay shows how they discuss and express opinions regarding three main keywords - historical awerness, use of history and source criticism, and finally, how they think they need to change the way they teach..

Undersökningens resultat visar att det finns betydande kostnadsbesparingar att göra vid införandet av en ny metod för askåterföring. Den nya metoden medför betydligt mindre transporter vilket leder till ett reducerat utsläpp av koldioxid och andra ämnen som har en negativ miljöpåverkan.I den nya metoden utnyttjas i viss utsträckning timmerbilarnas lediga kapacitet för transport av aska ut till spridningsområdet vilket då ökar chansen till högre lönsamhet för åkerinäringen..

This thesis compares different methods for risk assessment of a creosote contaminated site in Vansbro, Dalarna. In a complementary study the importance of using representative data for calibration and validation of stationary groundwater models is discussed. The time dependency between surface water levels and groundwater levels on the site in Vansbro is evaluated by step response analysis. The results show that the groundwater levels reflect only long-term variation in the surface water levels. Hence the use of such long-term means for calibration and validation of the stationary groundwater models is the only theoretically defendable alternative.As a first step in the comparison of risk assessment methods the degree of contamination is evaluated on the basis of generic guideline values for contaminated soils, developed by the Swedish Environmental Protection Agency.

This diploma work has been carried out in collaboration with the building contractor Sh Bygg Fastighetsutveckling AB in Uppsala with the intention to investigate how the height of a building affects various energy aspects such as transmission losses, infiltration, and the specific energy usage. Three different reference objects have been studied. The reference objects have been simulated for four different heights in the calculation program VIP-Energy.The results show that an increase in floor number can lead to both advantages and disadvantages. As the number of floors increases, transmission losses per square meter floor area decreases. However, as the height of the building increases, the reduction rate decreases.

Timber floating operations in Scandinavia during the 19th and 20th centuries has contributed to severe negative impacts on riverine ecosystems. Increase in water velocity and lack of stream bed heterogeneity as a result of stream channelization lead to increased bed load transport. Since availability and recruitment of new suitable spawning substrate in Scandinavian watercourses is sparse, spawning habitats for salmonids has become a scarce commodity. Lately, increasingly more attention has been given to the recreation and improvement of brown trout (Salmo trutta) spawning habitats in restoration projects. While much of the research on spawning habitat has been focused on evaluation of the influence that the constructed spawning grounds have on fish populations, few studies have been conducted to evaluate the persistence of these constructions over time. I evaluate erosion of constructed spawning beds as an effect of sediment transport attributable to water discharge.

Humans and dogs are both mammals. One of the differences between the two species is that man walk on two legs and dogs on four legs. There are also differences in the nerve system between the two species. The human nerve system is supposed to provide opportunity for fine motor tasks- while the nerve system of the dog is more focused on the ability to perform locomotor tasks. Humans need to increase their motor control and postural control when affected by various conditions and diseases.

Förr eller senare minskar tillgången på råolja och därmed bensin och diesel i världen. Då måste vi människor finna andra drivmedel för att klara våra transportbehov och andra behov som är beroende av drivmedel. Förutom detta finns det behov av åtgärder som minskar emissioner av CO2 till atmosfären. Etanol som drivmedel är relativt nytt, och marknaden är potentiellt mycket stor. Agroetanol AB är en etanolfabrik i Norrköping som använder spannmål som råmaterial.
