Background Atelectasis is a commun respiratory complication related to general anesthesia and may contribute to pneumonia and acute respiratory failure. Atelectasis apear within 10 minutes after anesthetization and occur in 90% or more anesthezied patients regardless of age and gender. The aim of this study was to indentify if there are any evidence for which methods are ultimate or are most efficacious to reduce and prevent the formation of atelectasis.                                                                                                          Methods This study is a descriptive litterature study where 28 scientific studies have been indentified for review and analysis.                                                                                                               ResultsThe use of 100% oxygen during the induction of anesthesia favors the developement of atelectasis. This can be prevented by preoxygenation with oxygen content of 100% combined with a PEEP of 6-10 cmH2O. When free airway is secured, oxygenation with 100% was found to be unnecessary.

Bakgrund: Forskning har visat att träning förbättrar den fysiska förmågan och höjer livskvaliteten hos personer med hjärtsvikt. Trots detta är det många personer med hjärtsvikt som inte deltar i gruppträning.Syfte: Syftet med denna studie var att beskriva vilka faktorer som personer med hjärtsvikt, som inte deltar i hjärtsviktsgrupp, upplever som hinder respektive möjligheter när de ska ta beslut om att delta i gruppträning.Design: Studien var en kvalitativ studie med deskriptiv design som utfördes genom semistrukturerade intervjuer med fem informanter.Resultat och slutsats: Resultaten, som tolkades utifrån beteendeförändringsmodellen Health Action Process Approach (HAPA), av denna studie visade att informanterna upplever olika hinder för träningen som har med prioritet, otrygghet, psykisk ohälsa, transportproblem och bristande information att göra. I vissa fall väljs träningen också bort på grund av att informanterna istället tränar i hemmet. Det största hindret enligt studiens resultat var bristen på information. Framförallt har informanterna bristande kunskap om träning som en del av behandlingen vid hjärtsvikt, NYHA II-III, och de effekter som träningen ger.

Bakgrund: Hjärtsvikt är den vanligaste orsaken till sjukhusinläggning hos äldre personer. Upp till 50 % av dessa patienter är felnärda. Detta kan delvis orsakas av de gastrointestinala symtom som sjukdomen ger såsom tidig mättnadskänsla, aptitlöshet och illamående. Syfte: Att ur patienters perspektiv belysa problematik med mat och kostråd vid kronisk hjärtsvikt. Metod: En litteraturstudie där tio kvalitativa eller kvantitativa vetenskapliga artiklar ingår.

The aim of this study was to increase the knowledge about whooper swan (Cygnus cygnus) ecology to enhance the ability to predict and also to prevent the crop damage they cause. The largest proportion of damage in Sweden has been reported at stopover sites during spring migration in February, March and April. Therefore, this study focused on an important stopover site, Lake Tysslingen, situated in south-central Sweden. Specifically, the relation between the duration and period migrating swans stage at the stopover site and mean temperature (measured at three different weather stations) for the years 2001-2010 was studied. Furthermore, the swans´ selection for certain fields in relation to field type, distance to roosting site, a supplemental feeding site and forest edge within agricultural land surrounding the lake was analyzed.

Den tekniska tjänsten är idag av stor betydelse för att Försvarsmakten skall fungera. Uppgifter inomden tekniska tjänsten är bland annat att hantera driftstörningar som inträffar på materiel och hantera uppföljningar av dessa inträffade fel. Syftet med den här uppsatsen är att undersöka två olika uppföljningssystem för driftstörningar, ett system från armén och ett system från flygvapnet. Utifråndetta diskuteras systemen ur olika synvinklar med fokus på bland annat fördelar och nackdelar. Under bakgrundsbeskrivningen av de olika systemen visade det sig att ARGUS och DA-flyg följer upp i två olika riktningar vid driftstörningar.

Through the birth and arise of the Internet people has been given great opportunities to make selective selfpresentations online, which in the long run has resulted in an easier retaining of the self- esteem than in the offline world. Simultaneously, the self- esteem has been viewed as a cause for both success and failure since it plays a vital role regarding our attitudes, emotional reactions and behavior. On this basis I wanted to study the relation between self- esteem and self-presentations closer. The purpose of the study is to describe and analyze how some users who publish training photos of themselves on Instagram experience how they present themselves within this forum and how these presentations affect/ are affected by their perceived self-esteem in their everyday life. The study is based on theories regarding self- esteem through Maslows? hierarchy of needs, the inner and outer self-esteem, and social comparisons.

Striga hermonthica, a parasitic weed, has long been believed to be correlated with the declining soil fertility status. However scientists have recently come to question this statement since some recent studies have shown contradictive results. To investigate whether soil fertility status and infestation of Striga hermonthica were correlated and the impact of it were caused by farmer management, 120 farmers in Western Kenya, where Striga hermonthica infestation is prone, participated in this study. In three districts with two sub-locations each, farmers answered a structural questionnaire and identified two fields, one with high and one with low soil fertility. These fields later came to be the basis for this study and soil were therefore also sampled from them.

De senaste åren har vikten av en trovärdig finansiell rapportering av hög revisionskvalité lyfts fram. En högre kvalité säkerställs genom att besluta om gemensamma regler och principer för revisionsbyråer. Intresset av revisionen är olika och således finns olika syn på syftet med revisionen och vad den bör innehålla. Tolkningsskillnaderna gör att hög revisionskvalité upplevs olika. Syftet med vår undersökning är att förklara ?hög? revisionskvalité utifrån revisorers och revisionens olika intressenters perspektiv samt att identifiera eventuella skillnader mellan revisorernas och dessa intressenters syn. En kvantitativ ansats har använts och utifrån teorin har sex hypoteser skapats.

Beef production in Sweden has traditionally been about rearing of dairy calves to slaughter. With reduced number of dairy cows and accordingly less dairy calves for slaughter, there has been a need for new forms of beef production in Sweden. In Västerbotten there are good conditions for beef production with a high feeding level of roughage due to favourable climate. The aim of this thesis is to, through interviews with ten farmers with beef production in Västerbotten, study what and with how much they feed their animals and link the results to production level. The thesis begins with a literature review where the general feeding standards and feeding recommendations for beef cows and growing cattle are examined.

This paper exposes the problems and challenges organizations face when integrating aged systems, web based systems and web services. The paper focuses on how people with different titles in an organization experience systems integration and the factors that contribute to project failure or success. The research methodology used in this is Grounded Theory and the resulting theory of this paper has taken form through the coding of transcribed interviews, which have gone through a constant comparing to other theories in the area of interest, mostly articles about success factors in system integration. The resulting outcome is a success model aimed to describe the underlying indicators to achieve project success.The success model consists of three factors that contribute to success in integration projects. The factors are: globalization, governance and balance.

The purpose of this essay was to examine the different aspects of motivational work with active heroin-using clients from a social workers point of view. The further purpose of this essay is to also examine what the advancements and discouraging factors in such a motivational work might be. To attain this purpose we focused on these following questions:What might motivational work with active heroin-using clients look like?According to the social worker, what factors constitutes for a beneficial progress in the engagement of motivational work with active heroin-using clients?According to the social worker, what constitutes for discouraging factors in the engagement of motivational work with active heroin-using clients?We chose to do a qualitative study by conducting separate interviews with six social workers working in a social services agency, all of whom are working with drug-addicted adults. We then analyzed the answers by using an abductive research strategy, testing the collected empirical data against our chosen theoretical perspectives.

It has been observed by both onion producers and a plant protection advisor on Öland (an island off the east coast of Sweden) that basal rot is the largest contributory factor to reduced onion quality and yield. Basal rot is mainly caused by species of Fusarium fungi. The aim of this study was to: a) investigate which species of Fusarium that can be found in onion produced on Öland, b) describe the symptoms caused by the different Fusarium fungi found and c) explore, through interviews with the onion producers on Öland, the mechanisms that may be involved in the observed increase in basal rot.Onion bulbs (Allium cepa) were sampled on two occasions. In total 181 onions from 11 different fields were analysed. In addition, eight onion producers were interviewed.

Sudan has always showed great potential in the poultry industry, but it has not been until now that this potential has blossomed and is growing quickly. As large agribusinesses1are taking over the market shares within the urban areas, smallholders2 have been put out of business. They are not able to compete with mass production and lack financial assets to improve their production techniques. Contract farming is defined as initiatives from agro industrial companies to secure access to smallholder produce and has in developing countries become a way of allowing the poor to participate in a larger market (Farrington, 1999). The aim with this study was to investigate the suitability of implementing the contract farming concept within the poultry industry in Sudan today. The study is a qualitative field study and the authors have conducted qualitative interviews with respondents involved in the poultry industry in Sudan.

The present study concerns a concept development of a product idea that Bengt Magnuson, associate professor, had when a heavy storm caused a widespread power failure of long duration. With a basic power-producing unit one should be able to get through a power loss. The product could also be useful for other tasks if different modules are connected, e g grass mower or snow-blower.According to the product idea the basic unit will be able to produce electric power enough for a fridge, freezer, TV, and a few electric lamps. Normally the basic unit can be used e g as a mower, when such a module is attached. An increased number of tasks would make the contraption useful and tempting for those who do not own an electrical power set in reserve.
