HIV-positive women?s sexual health: A meta-synthesis of how HIV-positive women experience and describe sexual health
There is no consensus of the concept sexual health in the context of being HIV-positive women. Research in the area tends to focus in different measurable parts of sexual health for HIV-positive women. A meta-synthesis on that research issue can develop a deeper understanding and knowledge of how HIV-positive women in qualitative studies describe and experience sexual health. The purpose with this study is to analyze and synthesize the results about how HIV-positive women describe and experience sexual health. The meta-synthesis follows Noblit and Hare´s method of meta-ethnography and additional use of Walsh and Downe´s checklist to appraise qualitative articles.
Stäng dörren tack : En observationsstudie om dörröppningar på operationssal
Bakgrund: Flera studier beskriver vikten av att minimera dörröppningsfrekvensen på operationssalarna. Högre frekvens av dörröppningar leder till försämrad ventilation på operationssalen, vilket i sin tur kan leda till vårdrelaterade infektioner.Syfte: Syftet med denna studie var att på en operationsavdelning observera frekvensen av dörröppningar under pågående operation, varför och av vem de öppnades.Metod: Metoden var en kvantitativ deskriptiv observationsstudie med tvärsnittsdesign. Personalen på en operationsavdelning i Mellansverige observerades under pågående operationer. Observationerna utfördes sex vardagar i januari 2013 och valdes från operationsprogrammet.Resultat och slutsats: 22 observationstillfällen observerades, 11 från vardera konventionell respektive infektionskänslig kirurgi. Studien visade att dörröppningsfrekvensen var högre vid konventionell kirurgi jämfört med infektionskänslig.
Ventilation i häststall
Dagens sporthäst lever idag under människans ansvar i stallar. I stallarna förekommer luftföroreningar, den med störst påverkan på hästen är luftburna partiklar som huvudsakligen härrör från strö och stråfoder. Föroreningarna kan orsaka skada i respirationsorganen, vilket medför att hästen får en minskad prestationsförmåga och de kan leda till allvarlig sjukdom. För att bli av med föroreningarna i stallet behövs en väl fungerande ventilation, med tillräckligt flöde, som kontinuerligt kan byta ut luften i stallet.
Förståelsen för problematiken med partikulära föroreningar i stalluften är dålig, bland annat för att även starkt förorenad luft kan upplevas som frisk.
En del av spelet : En studie av fotbollsdomarnas tillvaro i Gästrikland
There is a clear difference between the way football players and leaders regard the role of the referee, compared to the way the refereeing body looks at it. The refereeing body regard themselves as fundamental for the existence of the sport, while the other mentioned parties merely see them as functional justice makers. This view places the referees outside the field of football. This establishes a football culture, which is conflicted when it comes to the role of the referees on the field. The conflict comes to its edge in youth football, where the referees are under severe pressure.

Exclusion criteria were other interventions such as weight loss, changesin diet, medications or stress tests.Data collection and analysis Studies were selected after inclusion and exclusion criteria.
Event Marketing : En alternativ väg till kund lojalitet
Marks do not only work as an acknowledge of the effort that has been made under a long period of time, but also as a receipt for eligibility to further studies. Within the political debate, marks have often caused a big discussion among the political parties. That is due to the obvious difference between the political parties on the left, and their counterparts on the right. However, there is one thing that they all have in common. Everyone of them have plans of measure within their political agenda, regarding the use of marks.The aim of this study has been to try to understand the way pupils think about marks.
Inomhusklimat i ett statligt byggnadsminne
Statliga byggnadsminnen är byggnader som genom dess speciella kulturhistoriska värde är extra viktiga att bevara för framtiden. Att bevara, speciellt äldre byggnader, är inte alltid helt enkelt. En av utmaningarna i detta är att hålla ett lämpligt inomhusklimat i byggnaden för att förhindra en allt för snabb nedbrytningsprocess av material. Det finns tre lämpliga metoder för styrning av inomhusklimatet; Skyddsvärme, avfuktning samt styrd ventilation. Beroende på vad den byggnad eller det rum som studeras skall användas till och hur de unika förutsättningarna ser ut just där kan olika metoder vara olika lämpliga.

The purpose of the study was to investigate the use and losses of energy in an existing older building. Another purpose was also to look through various options for heating systems with renewable energy in the building. The aim was to reduce the use and losses of energy. The first step was to study the related electricity bills of the building and also perform measurements and calculations of the building envelope and ventilation. The next step was to find out the possible actions for energy saving by performing measurements and calculations.
Underlag för BREEAM-certifiering : Kristianstad Nya Galleria
The company Olofsfors AB manufactures drive belts for forest machinery, known as ECO-Tracks, and abrasion-resistant steel and cutting edges for graders, excavators and tractors, known as Bruxite and SharqEdges. Manufacturing these products requires the steel to be heated and molded, then submerged in water and hardened. The water used in the hardening of steel is pumped to the process from pits below the floor and then pumped back to the pit after it?s been used. Since the temperature of this water rises after being used to harden the steel the temperature of the pumping pit needs to be adjusted to maintain its setpoint of 21°C.
Karaktärisering av hårdmetallpulvrets råvaror och dess påverkan på pulvrets flödesegenskaper
This thesis has been done at the powder department (GH) at AB Sandvik Coromant in Gimo. With a rheometer measurements has been made on raw materials and powder blends. The focus of this report has been to find correlations between raw material powders and press data, comparisons have also been made between raw materials and powder blends.The rheometer can show information of how a powder act in flow conditions, together with air and with pressure. Analyses has been done comparing the rheometer data with press parameters (for example: rejected orders, weight variations and the compaction pressure) with the goal to find correlations between the powders flow properties and the powders compaction in production.The measurements and analyses have been showing that the powder flow properties depends on the powders composition and that properties like flow rate, aeration and permeability varies between powder blends and batches of the same powder sort. It seems to exist a correlation between the pressure force and the flow rate of a raw material.
Flödesmätning i vattenkraftverk : Studie av alternativa mätmetoder
Flow measurement is one of the greatest challenges in order to calculate efficiency in hydropower. Most hydropower plants in Sweden use differential pressure methods for flow measurement. These methods are dependent on constant conditions in the waterways. A change in these conditions, like turbine improvements, prevents differential pressure methods to verify efficiency improvements. Since efficiency improvements can?t be verified by one measurement system, another method, which isn?t affected by changing conditions, can be used.
Valberedning och tillsättning av styrelse enligt Svensk kod för bolagsstyrning: En studie av könsfördelning ur ett institutionellt perspektiv
Since July 2005 the major companies listed on the Swedish stock exchanges are required to apply the Swedish Code of Corporate Governance. The code states that companies shall have a nomination committee responsible for nominating new board candidates and seek to obtain gender equality in the Board of Directors. This paper examines the trend of board as well as nomination committee composition among Sweden's 60 largest publicly traded companies between 2005 and 2008. Our overall finding is that neither the board nor the nomination committee composition has changed to a notable extent during the period and that the share of newly appointed female board members has actually decreased. However, the trends vary between different sectors.
Turbinkretspump system - Kraftvärmeverket i Borås
The Rya power plant in Borås produces district heating, district cooling and electricity. The plant is owned by Borås Energi och Miljö AB and is run by Dalkia Facility Management AB.In order to get the best heat exchange from the district hot water a pair of twin pumps and a turbine circuit pump are used as return pumps. Turbine circuit pumps are used to increase the pressure through the heat exchangers at the power plant. The pumps are in use when the flow is over 2 000 m3 h-1 and during the summer when re-cooling is used to improve the effectivens of the heat boilers.Since the pumps, that are parallel connected, rotating at a fixed rate per minute, the pressure is regulated with regulating valves. This report shows that during the 4,300 hours that the pumps where in use, energy corresponding to 590 MWh was wasted.
Förekomst av agens i kattsnuvekomplexet på ett svenskt katthem
Conjunctival swabs from 12 cats in a Swedish animal shelter were analyzed by real-time PCR for FHV-1, Mycoplasma felis and chlamydiae. The purpose of this study was to see whether and to what extent these agents can be detected and if they were detected from cats housed in quarantine or in the adoption department. Samples were first taken upon arrival at the quarantine and then a second sample was taken two weeks after moving to the adoption department, or upon presentation of signs of disease. The cats spent the quarantine period in two separate quarantines: five in a new quarantine (quarantine A) and seven in a room in the old shelter (quarantine B). The difference between these quarantines was that in B the cats were often mixed together ant the hygiene routines were not as good as in quarantine A.
