This project is a step towards automatic firefighting. The goal is to decrease the number of personal injuries by replacing the human firefighter with robots or similar technical tools. Especially in very hostile environments due to risk of explosions or building collapse. A robot is easy to replace and can be maneuvered from a safe distance. The idea of the project comes from the company Drones Networking which aims for developing a totally autonomous firefighting system.

SyfteSyftet med föreliggande studie var att undersöka genomförbarheten av en hög-intensiv träningsintervention efter knäplastikoperation samt hur knäplastikopererade personers självvalda gånghastighet, maximal vadmuskelstyrka, vadmuskeluthållighet och självupplevda symptom, smärta, ADL funktion och hälsorelaterad livskvalité påverkas av tidigt insatt hög-intensiv styrketräning av vadmuskulaturen.MetodFemton forskningspersoner randomiserades till en träningsgrupp (n=7), som utförde hemträningsprogram i form av hög-intensiv vadmuskelträning samt till en kontrollgrupp (n=8) som utförde samma rehabiliteringsprogram som träningsgruppen utan hög-intensiv vadmuskelträning. En testprocedur genomfördes 3 respektive 12 veckor efter knäplastikoperationen. Självvald gånghastighet mättes genom ett 30 meters gångtest, vadmuskeluthållighet mättes med ett standardiserat tåhävningstest på ett ben, maximal isometrisk vadmuskelstyrka mättes med hjälp av en isometrisk dynamometer och självskattad symptom, smärta, ADL funktion och livskvalité utvärderades genom Knee injury Osteoarthritis Outcome Score (KOOS).ResultatDenna studie påvisar viss problematik med följsamheten i träningsregim för båda grupperna. Båda gruppernas sammanslagna resultat uppvisade signikant förbättrad självvald gånghastighet, maximal vadmuskelstyrka och uthållighet över tid. Trots detta ökade träningsgruppen den självvalda gånghastigheten signifikant mer än kontrollgruppen över tid.

Bakgrund: Stretching tros kunna förlänga muskelfascia, senor, ligament och öka en muskels tolerans för sträckning, så att muskeln kan slappna av längre in i rörelsen. Många teorier finns om vilken effekt stretching kan tänkas ha. Ett av dessa omdiskuterade områden är om stretchingen kan minska risken att drabbas av skador inom idrotten, något som i hög grad berör den sjukgymnastiska professionen. Syfte: Syftet med denna litteraturstudie var att ta reda på vilken evidens som föreligger för att stretching kan förebygga skador hos idrottsaktiva, samt diskutera vilket kliniskt värde detta kan tänkas ha för sjukgymnastyrket. Metod: Rapporten var en systematisk litteratursammanställning.

This report is about Swedish statistics on work related accidents and work related diseases onboard Swedish ships. The authors analyzed collected statistics from two authorities and an insurance organization in an attempt to compare the data. In order to understand the need for statistics and why the authority publishes them; minor literature study was conducted. The results of the literature study are in the background chapter. The requirements for the different cases to be registered in the statistics have been investigated, in unity with the issue in question.

Background Research concerning footing and its contribution to injuries has been conducted primarily in racing Thoroughbreds. Studies in UK and Japan indicate that some specific factors could be responsible for an increase in performance-associated injuries. Researchers in Sweden have performed studies on Standardbred trotters. More research is needed to be done on equestrian sports since requirements on footing are not exactly the same in riding and trotting horses. The lack of scientific evidence on the construction of equestrian surfaces has lead to anecdotal validation of designs.

Future climate changes may lead to an interest of alternative and foreign forest tree species in order to spread the risks in forestry. Douglas fir, Sitka spruce, Freemont cottonwood and hybrid aspen are examples of popular foreign tree species that along with western red cedar could have a future in the Swedish forests.Södra Skogsägarna and SLU have collaboration in establishment of foreign species in Swedish forests.The purpose of this study was to analyze and present the establishment of western red cedar, and to survey and illustrate injuries of freeze drying and other damages like deer browsing, vegetation and insect attacks. The study included four different provenances, and spruce as a reference, planted in two locations ? Asa and Släne.Western red cedar is despite its name a conifer of the cupressaceae family with defined secondary characteristic and gets along well with an overstory. Western red cedar grows often in mixed stands with similar conifers and its natural habitat is within and in the area near to British Columbia.The study included two series of field inventories, one made in the summer and one in the autumn 2013, three growing seasons after plantation.

Does playing have to hurt? - A quantitative study of ergonomics and double bass playing. This is a paper about ergonomics and double bass playing. I have studied the prevalence of playing-related pain in professional double bass players, teachers and students. This study is based on a questionnaire with 11 questions about double bass playing and pain.

In 2012, about 1.3 million boars were surgically castrated, most of them without anaesthesia. Castration is performed to avoid the occurrence of boar taint and aggressive and sexual behaviour. There is a growing concern about the welfare of the piglets and the Swedish Board of Agriculture is working to find efficient and functional alternatives to castration without anaesthesia. The aim of this study was to obtain an overall picture of the latest research about the alternatives to castration without anaesthesia, with focus on vaccination against boar taint, and how they affect the welfare of the pigs. The alternative methods that are available today are surgical castration with anaesthesia and/or analgesia, rearing entire males and vaccination against boar taint.

In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.

About 80 % of all Swedish dairy cows are kept in tie-stalls, but loose housing is increasing, probably because it is more profitable for the farmer. The design of the floors is of cruicial importance to the cows well-being. Traditionally, the most common type of floor in the alleys of a cubicle system still is a slatted manure-draining floor made of concrete. The typical Swedish design has 125-mm slats and 40-mm slots, maximally. With too wide slots, there is an increased risk of injuries to the claws when the cow makes a hasty move.

Background: Fall injuries are a costly problem for society, with costs ranging up to 14 billion a year. In addition to economic loss accidental falls also creates human value losses and reduced quality of life for its victims. In order to prevent the occurrence of injury related to accidental falls healthcare providers utilize various scientifically developed risk assessment tools, one of them being Downton Fall Risk Index. Method: Empirical, quantitative cross-sectional study. Objective: The purpose of the extended essay was to describe the categories in Downton Fall Risk Index that have a bearing on patients' risk of falling while in hospital and in municipal care, and to illustrate how nurses can use the fall risk assessment tool.

The determination of the optical properties of biological tissue is an important issue in laser medicine. The optical properties define the tissue´s absorption and scattering behaviour, and can be expressed by quantities such as the albedo, the optical thickness and the anisotropy coefficient. During this project, a measurement system for the determination of the optical properties was built up. The system consists of a double integrating sphere set-up to perform the necessary reflection and transmission measurements, and a computer algorithm to calculate the optical properties from the measured data. This algorithm is called Inverse Adding Doubling method, and is based on a one-dimensional transport model.
