Bakomliggande faktorer till presbyacusis; en litteraturstudie av mindre kända faktorer
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..
Forsmark 3 ?Ett Framtida Biobränslekraftverk?
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.

Glaset i Centrum : En fallstudie på New Wave Group
Seen in many trends and studies, consumers of today feel a growing desire to experience the uniqueness in products and services. This is forcing companies be more innovative and creative in their marketing, in order to distinguish and differentiate themselves and their products/services. We believe that creating a top-to-bottom experience strategy is one way that a company can succeed in this.The purpose of this thesis is to analyze and clarify how a business can reinforce their product experience through a complete experience strategy. In order to demonstrate this we have made a case-study research for the New Wave Group, advising them on how they can place blown glass art at the heart of the town of Kosta.The authors have used qualitative methods and an abductive approach. Four interviews have been completed with executives from the New Wave Group, including the project manager, hotel manager, head of the Kosta Boda smeltery and head of guides and visitors at Kosta museum.
Trycksa?rsincidens efter la?ngvarig kirurgi
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.
Modellering av reserv- och nödkraftsystem i JAS 39 Gripen
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.

Energieffektivisering av stenstadshusen - genom byggnadstekniska energisparåtgärder
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.
Pelletering av tallspån : grundläggande studier
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.
