Bakgrund: Studier visar att hörselskador kan uppstå till följd av yttre påfrestningar så som exponering av buller och kraftiga tryckförändringar. Fallskärmshoppare exponeras för bägge dessa faktorer, vilket skulle kunna innebära en ökad risk för att utveckla hörselskador. Trots detta är området mycket sparsamt studerat. En ökad kunskap inom området medför att eventuella behov av preventiva åtgärder kan identifieras.Syfte: Syftet med studien var att undersöka förekomsten av upplevda hörselbesvär hos fallskärmshoppare, samt om det finns något samband mellan upplevda hörselbesvär och antal hopp, användning av öronproppar eller akustiska höjdvarnare.Metod: Studien genomfördes i form av en kvantitativ tvärsnittsstudie. En webbenkät skickades ut till samtliga aktiva fallskärmshoppare med registrerad e-postadress i två fallskärmsklubbar i Mellansverige.

Comfort analyses regarding human induced vibrationsIt is not too common among civil engineers in Sweden to perform comfort analyses considering the vibrations caused by human activities. In addition, the Swedish standards lack requirements to be used for comfort analyses in design of floor-systems. The demand for large spans in combination with slender slabs, is today a reason to investigate the floor-system constructions, in order to prevent disturbing vibrations and oscillations.The purpose of this thesis is to create a guide for how a comfort analysis, considering vibrations, should be implemented. Göran Svedenbjörk who is an expert in structural dynamics has been interviewed where he presents his latest project Värtaterminalen and answers some questions about vibrations due to human activities.Floor-systems, consisting of concrete slabs supported by steel or concrete beams, have been investigated with simulations in the finite element program Abaqus. In the simulations, the influence of various factors on the natural frequency of floor-systems and the acceleration level caused by dynamic loads, is studied.

Bakgrund: Abort innebär att graviditeten av olika skäl avbryts. En abort kan vara spontan eller inducerad, och den kan ske antingen medicinskt eller kirurgiskt. Sjuksköterskans roll vid en abort är att stötta kvinnan genom hela processen.Syfte: Syftet med studien var att undersöka sjuksköterskans attityder och upplevelser av omvårdnadsarbetet med kvinnor som genomgår en abort samt vilka faktorer som påverkar dessa.Metod: Studien är en litteraturstudie med deskriptiv design. Studien är baserad på 13 vetenskapliga artiklar som har sökts fram genom databaserna Cinahl och PubMed.Resultat: Denna litteraturstudie visade inte på några entydiga attityder hos sjuksköterskan vad gäller abort. Sjuksköterskan kunde känna skuld, depression och skam.

Syfte: Syftet med denna studie var att undersöka kvinnors upplevelser av stöd och bemötande från vårdpersonalen i samband med hemabort.Metod: I studien har en kvantitativ, deskriptiv, komparativ tvärsnittsdesign använts. Urvalet skedde konsekutivt och som datainsamlingsmetod användes ett frågeformulär. Utifrån detta frågeformulär utfördes telefonintervjuer med studiedeltagarna.Resultat: Nästan alla kvinnor som deltog i denna undersökning tyckte att de fått bra stöd från sjukvårdspersonalen i samband med hemabort. Det fanns inga skillnader i upplevelsen av stödet beroende på kvinnornas ålder eller om kvinnorna hade tidigare erfarenheter av abort eller barnafödande. Angående andra upplevelser vid hemabort relaterade till det upplevda stödet från sjukvårdpersonalen visade denna studie att de flesta var nöjda med den information de fått beträffande abortprocessen, normal blödning i samband med abort och smärta.

Spitz nevus was first described by Sophie Spitz in 1948 as juvenile melanoma. The lesion is a benign melanocytic tumor, which consists of epiteloid- and spindelshaped cells. Histological is spitz nevus difficult to distinguish from malign melanomas and spitzoid melanomas. Loss of symmetry, loss of maturation in the deep component, nuclear polymorphism and hyper chromatic nucleus are features which can be found in melanomas. Some of these features are often seen in spitz nevus.

Handling, loading, transport time and unloading in connection to transport of farm animals affect animal welfare. Induced effects include both psychological and physiological stress responses in animals. The physiological parameters may be measured through blood analysis while behavioural changes often manifest themselves through increased vocalisation, escape attempts and apathy. Physiological parameters are additional parameters of importance when measuring animal stress responses. The handlers behavior during transport has been shown to have major impact on animal welfare and the quality of meat. Animal friendly handling and driving of animals create a more manageable work environment for the handlers. To further increase animal welfare in connection to transport, stables should be built with well adapted drift passage and ramps on the transport vehicle.

Barley is one of the most important cereals cultivated in the Nordic countries. Climate change brings warmer and moisture climate which favors fungal diseases. In the cropland barley can be seriously infested with hard fungus attack. Since it is important that the yield bears a high quality it is of great importance to find varieties more resistant to attacks.Pathogenesis-related (PR) proteins are stress proteins induced in the plant in response to infection and abiotic stress (van Loon, 1997). PRs are shown to have antimicrobial activity differing between bacteria, fungi and oomycetes (Tandrup Poulsen, 2001).

Bovine viral diarrhoea virus (BVDV) is the causative agent of a complex of disease syndromes in cattle with high economical and welfare impacts. BVDV occurs as two biotypes; cytopathic (BVDVcp) and noncytopathic (BVDVncp) determined by differential effects on cultured cells and can also be divided into two genotypes (BVDV1 and BVDV2) on the basis of genomic diversity. The interaction between BVDV and the host?s immune system is regarded a key aspect in the sequel of BVDV infection. Infection with BVDV normally causes an acute transient infection, with mild to subclinical signs, but occasionally results in severe and even fatal disease.

Bakgrund: Internationellt existerar fortfarande illegala aborter med kvinnans hälsa, och i somliga fall liv, som insats. Inom gynekologisk vård i Sverige arbetar allmänsjuksköterskor vilka vars arbetsuppgifter bland annat består av att vårda kvinnor som genomgår inducerade aborter. Deras arbete vilar på den svenska abortlagens bestämmelser om kvinnans rätt till fri abort samt den övergripande hälso- och sjukvårdslagen. Allmänsjuksköterskor har fått en mer framträdande roll i arbetet med inducerade aborter i takt med den ökade användningen av den medicinskt inducerade aborten. I sitt arbete ställs sjuksköterskorna inför specifika arbetsuppgifter vilka kan tyckas påfrestande.

Cellulose nanocrystals (CNC) are great candidates for composite materials. The reasons why CNCs are such attractive materials for them are due to their great mechanical properties, high aspect ratio and low density. On the other hand, hydroxyapatite (HAp) is a kind of calcium phosphate and a main component of bones and teeth. The purpose of the present study is to make oriented nano-sized composites with CNC and HAp. Although some researchers carried out to make CNC composites with HAp for biomedical materials, nano-sized and oriented ones haven?t been achieved yet.

Kvarstående betäckningsinducerad endometrit är ett stort problem inom hästnäringen och så även andra typer av endometrit. Detta är den främsta orsaken till infertilitet hos ston. Vissa ston är nämligen oförmögna att klara av den inflammatoriska reaktion som normalt följer av betäckning (för att eliminera sperma och patogener) eller så drabbas de lättare av kroniskt infektiös endometrit, oavsett betäckning. Det finns otaliga förslag till förklaringar till varför de inte kan hålla uterus fri från inflammation såsom defekta myometriekontraktioner, stoets reproduktionshistoria eller anatomiska aspekter (t.ex. pneumovagina, otillräckliga mekaniska barriärer eller en horisontell uterus).

Background: Evaluation of lameness in horses is traditionally performed by a veterinarian who subjectively evaluates the movements of the horse. Accordingly, lameness diagnosis varies with the veterinarian and circumstances for which the horse is examined. Research within the area has long tried to establish an objective and standardized method for lamenessevaluation in horses. Several methods have been shown to be reliable and are used regularly within research, for example measurement of forces between the hoof and ground, and measurement of movements with high speed cameras or accelerometers. However these methods require considerable preparation, standardization, and expensive equipment as well as produce large amounts of data that are incomprehensible for the clinician.

The past and ongoing structural change in Swedish agriculture has led to an increasing number of large-scale farms. The biological factors associated with large-scale farming operations may cause increasing variability, risk and reduced yields due to sub-optimal timing and management of field operations. The theory of economies of scale suggests that largescale production may benefit from lower costs due to scale efficiencies. Thus, large-scale farms may face cost reductions in terms of long term inputs factors, e.g. agricultural machinery.
