Trycksår är en vårdrelaterad skada vars prevalens är utbredd på sjukhus i Sverige. Denna hudskada uppkommer när ett ihållande tryck orsakar att underliggande vävnad skadas. Riktlinjer finns utformade för hur preventionsarbetet med trycksår ska utföras, och syftar till att minska prevalensen av trycksår. Syftet med studien var att undersöka sjuksköterskors syn på trycksårsprevention relaterat till patienter som ligger inlagda på somatisk vårdavdelning. De undersökningsmetoder som användes var av både kvalitativ och kvantitativ ansats. Materialet samlades in via enkäter och det slutliga informantantalet uppgick till 29 informanter.

It is important to keep a high standard of service and customer care to be able to keep your position on the market. The focus of the paper is to study how a store manager can influence their employees to perform better on the job, in terms of service to customers and increased sales. The aim is to analyze the different tools store managers use to motivate their employees with the goal of improving service to the customer and to increase sales.

It's an everyday experience shared by many that nature can be of help in relieving pain, reducing stress, support mental recovery etc. In the last three decades or so this experience has also found support in a large number of scientific investigations. Among other things the experience of nature has been shown to reduce stress and pain in patients and to boost concentration and reduce impulsive behavior in children. Most of this research however has mainly been concerned with the visual modality. In this thesis the aim has been to focus on the auditory modality in this context by trying to reveal some effects on people from the exposure of nature sounds played indoors in three different environments: a grammar school class room, a kindergarten play room and a post-surgery wake up room at an intensive care unit.

Många byggnader är idag fuktskadade. Fuktskador uppstår på så väl nya som gamla byggnader. Idag provtrycker man hus för att få ett värde på dess täthet, men många hus som klarar täthetskraven drabbas ändå av fuktskador. Detta beror på att otätheterna är lokala på en eller flera delar av klimatskalet bortsett från otätheter vid anslutningar.  En studie har gjorts på två väggtyper; en standardvägg och en passivhusvägg.

The purpose of this master thesis was to study the water system for mechanically cleaned water at Skärblacka mill, in order to find and evaluate possibilities of using energy more efficiently. The thesis also includes an evaluation of the software tool ?Pumpanalys?Skärblacka mill produces pulp and paper. The large amount of water required is cleaned mechanically through filters and called mechanically cleaned water (MR0). The MR0 water is pumped out to the factory by four crude water pumps.

Studiens övergripande syfte är att belysa och gestalta det sociala stöd respektive sociala tryck personer sjukskrivna för utmattningsdepression anser sig uppleva från omgivningen, vad gäller både att vara sjukskriven och att återgå till arbete. Undersökningen genomfördes med hjälp av kvalitativ metod, och sex personer som var sjukskrivna för utmattningsdepression intervjuades individuellt. Resultatet visar att de sjukskrivna upplever en komplex blandning av både press och stöd i processen att ta sig tillbaka till arbetslivet. Stödet, oftast i form av förståelse och undvikande av press, upplevs främst från personer i individens nära omgivning, medan pressen att återgå till arbete oftast relateras till personer och grupper på längre avstånd. Störst press att återgå till arbetet upplevdes från den "samhälleliga" normen "att göra rätt för sig", men även omgivningens okunskap och brist på förståelse upplevdes som en press. .

Lattelement AB in Ornskoldsvik is one of the leading companies in Sweden in composite elements in walls, floors and roofs in particular. The company supplies elements to buildings located with a wide geographical variation, which means that the products are subjected to very different climate with regard to snow, wind and humidity. This places high demands and requires the elements to withstand large variable loads.The elements are made of lightweight beams with flanges of structural timber and beam webs made of OSB. These are bound together by nogging pieces with the same kind of structure. On top of the beams a nailed and glued plywood is added to absorb compressive forces and on the underside of the element a sheet of steel is added for tensile absorption.These elements are then attached to the building framework in different ways depending on the particular element height, loads and the structual supporting material of the frame work.

Background: More than half of the elderly (65-84 years) in Sweden have problems with hearing. In some studiesit?s discussed if age related hearing loss or presbyacusis is a part of natural aging or if it depends on underlyingfactors.The purpose of this literature study was to analyse scientific papers which illustrate correlations between lessknown underlying factors and presbyacusis, defined from psychoacoustic and/or neurofysiological tests.Material and method; Literature study where scientific papers, relevant to the purpose of the study and thequestions at issue were found in the database PubMed.The result shows that cardiovascular disease, hormones, diet and drugs have an influence on presbyacusis. Thehealth condition of the individual and their lifestyle matters, likewise estrogen which according to the results of 2studies has a protective effect on hearing.Conclusion; The studies show that heart attack and high systolic blood pressure in women have a correlation topresbyacusis, but not in men, - the hormone estrogen, - some vitamins, antioxidants and diet have a protectiveeffect on hearing and studies show that smoking and alcohol have negative effects..

Recent turmoil surrounding nuclear power as an energy source, especially since the accidentat Fukushima, has largely contributed to the debate of whether or not nuclear power should beused as an energy source. This study has examined the economic feasibility of replacingForsmark?s 3rd nuclear reactor with a bio fueled power plant, and find out how this could bedone.The power generation that has to be replaced is equal to 1170 MWe. To replace this, 6 largescaleCFB-boilers, each providing over 200 MWe, were necessary. In addition to this, eachboiler required their respective turbine sets, comprising one high-pressure-, and one lowpressureturbine with intermediate reheating capacities.Based on this, a rankine-cycle was modeled using the software EES, to be able to calculatethe total heat required in the power plant.

Trycksa?r a?r ett fo?rekommande problem inom den kirurgiska omva?rdnaden som leder till o?kade va?rd- och samha?llskostnader samt ett o?kat lidande fo?r patienten. Det a?r av stor vikt att va?rdpersonalen arbetar fo?rebyggande fo?r att motverka uppkomsten av trycksa?r samt att i god tid uppta?cka om ett trycksa?r har uppsta?tt.Syftet med denna studie var att underso?ka trycksa?rsincidens efter la?ngvarig neurokirurgisk kirurgi, identifiera vart trycksa?ren uppsta?r och om de kunde kopplas till riskfaktorer.Metoden som valdes var en kvantitativ prospektiv kohortstudiedesign fo?r att resultatet skulle kunna anva?ndas i den peroperativa och postoperativa omva?rdnaden. Hudkostymen inspekterades tva? ga?nger postoperativt pa? tjugoen patienter.Resultatet visade att 76 % av studiedeltagarna hade trycksa?r efter operation och det vanligaste fo?rekommande omra?det var ha?larna.

Simulation is a vital tool during development of JAS 39 Gripen, since money and time can be saved.The Auxiliary and Emergency Power System, AEPS, is a subsystem of the secondary power system in Gripen. It has the function of providing the aircraft with electrical and hydraulical power before activation and after deactivation of the main engine. The system also functions as backup in case of a safety critical problem in the main power supply system. The system basically consists of a control unit and an auxiliary gearbox. The gearbox is driven by an air turbine.

The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

Wood pellets are an upgraded product of residuals from several wood processing industries, for example saw mills and pulp industries. The pellets are produced by pressing the milled and dried sawdust to cylindrical units with a higher density than the initial raw material. Pellets have great benefits compared to the raw material: high energy per volume, good transport and storage properties and homogeneity. Several parameters collaborate in the whole process, which makes it complex. Wood is a heterogeneous material, chemically and structurally dependent on wood parts, habitat and storage procedures.

In the wake of the latest financial crisis, a group of individuals launched the Occupy WallStreet movement. It wanted to change the structures that economic and political life arefounded upon. They believe that the established structures are unfair and exploit the majorityof the population. Researchers critisised the movement saying it was ambiguous because itcould not produce any realistic ideas for change, while others thought that was a success forthe movement.Therefore, the aim of this Bachelor Thesis is to examine the different ideas articulatedby the Occupy movement and present them systematically. Through an inductive qualitativetext analysis six different themes are identified regarding how the movement wants to changethe structures in society to make them fair.
