A serological study of Rift Valley Fever virus in two regions in Tanzania

Rift Valley Fever (RVF) is a disease caused by Rift Valley Fever virus (RVFV), which is an arbovirus. An arbovirus is a virus that is transmitted by an arthropod vector, in this case a mosquito. The virus is a member of the Phlebovirus genus in the family Bunyaviridae. It was first identified in the Rift Valley in Kenya in 1930. The disease is a zoonosis but mainly affects domestic ruminants inducing massive abortions and a high mortality among young animals.

Hälsan i behåll? : en studie av sjukdomsbilden i det vikingatida Fröjel, Gotland

13 individuals from the Viking Age trading place in Fröjel, Gotland, were examined for this thesis. The aim was to gain a deeper knowledge about the individuals, and the main focus was to study their health. Three men, eight women and two children were examined. The age of the two children was estimated to around birth, and was no longer relevant for this thesis. The age distribution showed that two individuals were young (10-24 years), seven individuals were adults (18-44 years) and two individuals were middle-aged or older (35-79 years).

Honung och biodling : honungens ursprung, egenskaper och effekter på människans hälsa

This report describes honey, its origin, properties and effects on human health. Honey has been used for a long time in most civilizations and apiculture is an important activity sector in many parts of the world. The trend is an increase in honey production but a decrease in the number of beekeepers in Sweden. Honeybees live in a highly developed society with a strong hierarchy and a well organized distribution of the tasks. They visit a broad spectrum of plants and collect nectar to store it as honey.

Anestesi vid kastration av spädgris :

An overwhelming majority of all male piglets are castrated without anaesthesia when they are very young. In Sweden this means that approximately one and a half million piglets are castrated every year. The reason the piglets are castrated is the strong and unpleasant smell and taste, the ?boar taint? that the meat from intact boars sometimes exhibits. Boar taint is chiefly cause by androstenone and skatole, two compounds that are mostly produced by sexually mature boars and are accumulated in the subcutaneous fat.

Svarstiden vid klinisk bedömning av högre språkliga förmågor hos vuxna

The aim of the present study was to investigate response time variations in tasks for assessment of high level language functions and how response time is related to education, age and gender. Response time is defined as the time to complete a task after it has been presented. 103 subjects, aged 20 to 80 years, were tested with the Assessment of Subtle Language Disorders, Sentence analysis and Morphological completion. The subtest Comprehension of ambiguous sentences showed the longest response time and Morphological completion the shortest. Correlations were found between increasing age and longer response time for Comprehension of metaphors and between education and response time for several subtests.

Ternära koder för variabelt felskydd

Ternary codes for unequal error protection is a part of a communication system where different parts of the information to be transmitted can receive different amount of error protection. There are a lot of applications where the channel conditions fluctuate so that reliable or acceptable communication can not be guaranteed. Regardless whether the fluctuations of the channel are intentional or not the idea is to let the coderate decrease so that the error correcting capability can increase for the part of the information to be more protected. By using the support, the nonzero positions of the ternary code, a new binary code can be extracted with properties different from the ternary code in the sense of cardinality and minimum Hamming distance. When the channel conditions are good the receiver decodes the message using ternary decisions and receives all information included in the codeword.

Fånggrödor i Norra Östersjöns vattendistrikt

70 % of the lakes and waters in the water district of northern Baltic Sea do not reach the requirements for good ecological status. This is mostly due to eutrophication caused by a too high deliverance of nutrients from agricultural land or effluents. Losses of particulate phosphorus through water erosion contribute to a great extent to this eutrophication. In the action plan for the water district cover crops are mentioned as a measure for reducing losses of phosphorus from arable land. This paper reviews the possible effect of cover crops in the water district and discusses what crop that would be most suitable.

"Ett liv i två världar"  : En kvalitativ studie om hur pojkar konstruerar etnisk och religiös identitet i olika sociala kontexter

"One life in two worlds" is a qualitative study of Syriac boys constructs ethnic and religious identity in different social contexts.Based on these three questions: how do the boys describe the importance of the parents' cultural and religious background in relation to their own identity? How do the boys describe their experiences of being categorized in school? Which significance is given to religion and ethnicity when the boys describe their experiences in relation to home and school context?I did reach the aim of this essay which was to investigate by interviewing the Syrian boys how they construct or reconstruct ethnic and / or religious identity in relation to different social contexts with a focus on the home and the school.In this study, I assumed the qualitative method in which I interviewed six Syriac boys who attend grade nine. The starting point of the study was social constructivism. Therefore, knowledge in this study is seen as something that is constructed in language, social and cultural interactions. The reality and perspective of reality is socially constructed, meaning that knowledge is created through the interplay of common action.The results of this study show that all the informants are agreed that their parents' ethnic background has had and has great significance for their identity formation.

Kartläggning av symtom på depression hos patienter med hjärtrytmrubbningar

Cardiac arrhythmias and heart diseases can result in a limited performance capacity which could lead to anxiety and depression. Objective: The aim of this study was to investigate the prevalence of symptoms of depression among patients with cardiac arrhythmias. The intention was also to explore differences between men and women in the occurrence of symptoms of depression. Furthermore, the prevalence of symptoms of depression among patients with cardiac arrhythmias was compared with a Swedish general population. Method: For two weeks MADRS-S, a self-rating scale for depression, were distributed at a medicine ward where patients with cardiac arrhythmias are treated, at a hospital in Sweden.

Omvårdnad av familjer till hjärtsjuka barn

Syftet med denna litteraturstudie är att belysa omvårdnaden för familjer till barn med hjärtfel ur ett familjeperspektiv. Vården av hjärtsjuka barn och ungdomar kräver en kunskap om dessa sjukdomar inte enbart hos sjukvårdspersonal inom den högspecialiserade barnkardiologin utan inom ett flertal andra specialiteter. Studien omfattar sjuksköterskans omvårdnad av familjer, förberedelser för hemgång, samarbetet mellan olika yrkeskategorier, familjens reaktioner vid denna krissituation och de bearbetningsmodeller som finns till förfogande för att underlätta bearbetningsprocessen. Vidare forskning inom detta område är nödvändig. The purpose of this study is to illuminate the care of families to children with heartdisease from a familyperspective.

En uppföljning av analysresultat (serologi och virus) av EAV på seminhingstar i Sverige år 2002 och 2005. :

EVA, Equine Viral Arteritis, was diagnosed for the first time in 1953 in USA. The disease gained international interest in 1984, when there were several outbreaks of abortion at Thoroughbred studs in USA. EAV, Equine Arteritis Virus, is an RNA virus in the Arteriviridae family. There is only one serotype of EAV but several strains and the strains have different virulence. EAV is transmitted in two different ways: by aerosols, or by venereal transmission.

Odour-mediated behaviour in codling moth, Cydia pomonella : do fermentation odours affect the attraction and oviposition behaviour in codling moth?

The codling moth, Cydia pomonella is a common pest in apple orchards and can be found worldwide. Feeding by codling moth larvae can cause a substantial decrease in apple yield. Control methods comprise for example the use of pesticides, viruses and pheromones. As a sustainable control method, pheromones have been successfully applied to disrupt moth mating behaviour. Other behaviours like foraging, search for mating sites or host finding could be potential targets for additional odour-mediated behavioural manipulation but need further investigations of the underlying odour stimuli and behavioural plasticity. Many insects are attracted to the smell of fermenting fruit and associated microorganisms.

Alla barn är lika mycket värda : En kvalitativ studie om hur barn framställs i KappAhls reklamfilmer

I have written an essay called ?All children are equally worth - A qualitative analysis of how children are produced in KappAhls commercials?.The purpose of this thesis is to do a study of the swedish clothing company KappAhl?s commercials. My purpose is divided into three questions: With which clothing colours are girls and boys represented in the commercials? Is there any difference in the making of ?non-white? and ?white? children in the commercials? and What is being transmitted in KappAhl?s commercials, where the focus should lay on the clothes?My material consists of three selected video clips from KappAhl?s Youtube channel. The three commercials are named: 1, Back to school, 2, Children?s christmas and 3, KappAhl 3 för 2 på alla överdelar för barn (translation: KappAhl 3 for 2 on all children?s tops).

Genetisk variation av betydelse för mjölkkvalitet i Rödkullerasen :

The Swedish Red Polled breed is threatened by extinction and there are only around 1100 animals left. The breed was popular in the early twentieth century, but since then the numbers have steadily decreased. The overall objective of this study was to find out whether there may be economic incentives for preserving the breed. The milk quality properties are of major importance in the production of dairy products. Therefore we would like to establish if the Swedish Red Polled breed carries favourable alleles at loci of relevance for milk quality, to potentially make the breed more interesting for milk production.
