What affects Hiv in South Africa's different provinces? This thesis examines if education, unemployment rate, GDP per capita, and the literacy rate has any relationship with the Hiv prevalence. This is analyzed using theory and data in the form of a simple microeconomic model and an econometric regression analysis based on cross sectional data of the provinces of South Africa. The regression analysis shows that unemployment rate and education have significant effects of the Hiv prevalence in South Africa. The microeconomic model in the thesis indicates that when education is higher, individuals are more aware that the probability of being infected by Hiv is higher when the Hiv prevalence is high.

Syftet med denna systematiska litteraturstudie var att ta reda på vilka mätinstrument som används för att identifiera patienter med risk att utveckla trycksår samt beskriva vilka omvårdnadsåtgärder som har betydelse för trycksårsprevention och sårläkning. De vetenskapliga artiklarna (n=16) som ingick i denna studie söktes i databasen Elin@dalarna. Sökorden som användes var pressure ulcer i olika kombinationer med nutrition, activity, skin, Norton, treatment och hydrocolloid. Inklusionskriterierna var att artiklarna skulle vara publicerade mellan åren 1999-2006 och vara i fulltext samt svensk och/eller engelskspråkig. Resultatet visade att patienter borde riskbedömas för trycksår så snart som möjligt efter att de anlänt till vårdinrättningen.

BACKGROUND: Today?s societal changes, including high rate of change and increasing information flows, are increasing the demand on the individual mental capacity. It becomes increasingly difficult to analytically process all the different dilemmas and everyday decisions as individuals have a limited mental capacity available to make these decisions. Thus, it has been suggested that ego-depleted relies more heavily on intuition, which is less burdensome, when making decision. However little is known about to what extent intuitive decisions differ from analytic.

Lately the popularity to keep different species of dwarf hamsters has increased in Sweden. The requirements of the Swedish legislation to keep hamsters as pets are low which could be a reason for the increasing popularity. Hamsters are in nature generally nocturnal and can travel far distances to find food sources during their active part of the day. Their eyesight is poor, but is compensated by their well-developed hearing and olfaction. ?Run about balls? are made of plastic and the hamster is placed inside it where after the ball is placed on the floor and the hamster can then run protected outside the cage.

The purpose of this study is to investigate how the legal protection against sexual harassment at work functions, and where to draw the line. The study is limited to focus on the sexual harassment directed at women from men, because it usually occurs that way even though only a few report the incidents. The results are discussed from a gender perspective on how the distribution of power is between men and women as a way to explain sexual harassment.Sexual harassment is currently protected by the discrimination law and the EU principle of equal treatment for men and women. For a behavior to be considered as sexual harassment it has to be unwanted by the receiving party and the person practicing the harassments must be aware that the behavior is perceived as offensive. The behavior shall be of a sexual nature and contribute to a disadvantage for the victim in the form of a violation of that persons integrity.It is the victim that determines whether the behavior is perceived as sexual harassment or not, what one person believes is a friendly behavior may be perceived as offensive by another.

Background: Previously research shows that people treated conservatively can have reduced foot function after Achilles tendon rupture. However, there are few qualitative studies in the subject, so this essay is written to provide a deeper understanding of how these people feel about their foot function one to two years after the injury.Purpose: Investigate how people perceive their foot function after conservative treatment one to two year after Achilles tendon rupture and if they have an avoidance behavior in their everyday lives.Method: Four people who suffered from Achilles tendon rupture participated in this qualitative study. The study was conducted with semi-structured interviews, which in turn were processed using qualitative content analysis.Results: The perceived foot function is today varied in terms of mobility, strength and pain according to the participants. They feel difference in their everyday life in comparison with before the injury. It appears that participants have avoidance behavior when it comes to the situation of injury.

Hallsta paper mill uses large amounts of water during the pulp and paper making processes. The wastewater is treated in two separate activated sludge processes referred to as BIO 1 and BIO 2. The main aim is to reduce the organic substance content, measured as COD (Chemical Oxygen Demand) before the wastewater is released into the environment. Since the effluent produced is very rich in organic substances, the addition of nitrogen (N) and phosphorus (P) are necessary to give satisfactory treatment results. Problems with sludge bulking sometimes occur which lead to increased levels of suspended matter and nutrients in the effluent.

ABSTRACTThe privatization of pharmacies in Sweden took place in 2009, in part with higher availability of medicines as justification. For a good adherence, the patients needs a good availability of medicines from pharmacies. The aim of the study was that two years after the pharmacy reform study older people?s opinions on drug supply and pharmacy services, and which pharmacy chains they know about and use. The method used was a quantitative cross-sectional study and was conducted using questionnaires.

Blodtrycksmätning är en viktig del i en sjuksköterskas arbetsuppgifter och då både manuell och digital blodtrycksmätning idag förekommer parallellt inom svensk sjukvård syftar denna studie till att undersöka om det finns någon skillnad mellan de uppmätta resultaten i dessa mätmetoder och beskriva denna eventuella skillnad. Undersökningen genomfördes på en kärlkirurgisk avdelning på ett sjukhus i södra Sverige under hösten 2009. Populationen bestod av 38 inneliggande patienter som följdes upp med totalt 65 blodtrycksmätningar. För att utföra undersökningen tillämpades cross-over design med kvantitativ ansats. Resultaten visade skillnader mellan de två mätmetoderna då den digitala metoden uppmätte högre blodtryck än den manuella. Digital blodtrycksmätning visade genomgående högre mätresultat jämfört med manuell metod.

During pulp and papermaking process a huge amount of water is used. The wastewater contains a large amount of pollutants and has to be treated before it reaches the recipient. In March 2004 a new bleaching plant was started up at SCA Graphic Sundsvall AB, Ortviken?s paper mill using peroxide. The production of bleached thermo mechanical pulp and thus the load to the wastewater plant increased.

In some herds it has been observed that extremely short teats have become a problem; with a negative influence on the milking performance. The aim of this study was therefore to investigate to what degree the quality of the teats and the milk in cows with short teats is affected as compared with cows with normal teat length and furthermore if the milking performance could be improved by using a liner adapted to short teats. This study was divided in two parts. In the first part, it was examined if there were any differences between short teats and teats with normal length with reference to the milking performance, udder emptying, teat treatment, milk quality, and udder health. 11 pairs of cows were used and in each pair of cows one cow had teats shorter than 40 mm while the other cow had teats longer than 50 mm.

The aim of these two studies was to investigate the possible physiological, behavioural and emotional changes that appear after human-horse interactions and also to find an explanation to why they occur. One aspect that is discussed is whether the wellbeing of humans can be coupled to interacting with horses and of how the animals respond to the interaction. The first study was performed on 9 horses and their owners, both parts being subjects to registrations during 4 different interaction treatments. The second study was performed on 6 horses with registrations only being performed on the horses during 2 different treatments. Nine horses underwent 3 different treatments all performed by their owners (H = stroking of the horses forehead, B = brushing and M = stimulation of the withers) in addition to a control round (K). Each treatment lasted for 4 minutes but observations were performed until after 45 minutes from start.

This thesis deals with the concept of how price affects demand for a good by estimating various price elasticities of demand for snu sold in Sweden. Information was gathered on price development for snus and cigarettes as well as sales data from Swedish Match, the largest supplier of snus in Sweden. Income-, price- and cross-price elasticities were estimated based on log-log regression. Results show that snus is an inelastic good since the coefficient for price of snus was -0.536. This proved that a 1% increase in price causes a 0.536% decrease in quantity demanded.

Today dairy farmers in Sweden are obligated to have lights turned on during night time in addition to the mandatory daylight inlet. This presents a cost for the production but many argue that it can be economically beneficial, especially in loose housing of dairy cows. In loose housing and even more so in herds with automatic milking, well functioning cow traffic during all hours of the day is crucial to optimise production. In order to keep the cow traffic flowing, lights may be an important management tool. It is also perceived among farmers with tied up stall that night light decreases the incidents of cows accidental stepping on their own or neighbours udders.

Inledningsvis belyses generella faktorer som påverkar ansikts- igenkänning. Därefter läggs fokus på cross- race fenomenet, vilken studien syftar till att undersöka. Uppsatsen grundar sig på två hypoteser som båda berör förmågan till igenkänning av ansikten från den egna samt av annan etnisk grupp. I studien deltog två grupper (N = 63), kineser och svenskar som testades med ett bildspel uppdelat i två delar. I instuderingsfasen visades 21 ansikten, med jämn fördelning av asiatiska, afrikanska och europeiska ansikten.
