For several years Uppsala University together with several companies has been involved in a WISENET project aimed at improving railway transport security. By placing a sensor system near the wheels of each wagon, the temperature of the bearings can be measured and transmitted to a collector placed centrally on the wagon. This in turn transmits the collected data to RFID receivers placed intermittently along the railway.As the signals are transmitted wirelessly, problems may occur as the antennas get dirty or coated with ice and snow. To determine the effects of these coatings, several tests were performed examining the reflection coefficient S11, the impedance Z11 and the efficiency eta of an antenna, and how they varied when various coatings were placed over the antenna. Examined coatings were ice, snow and water to determine the effects of weather, and various metal-based coatings: powdered iron both pure and partially oxidized, and iron ore granules.

Background:Alzheimer's disease is a disease that primarily affects the elderly but also younger people. Alzheimer's disease is a type of dementia which means that you get changes in the cerebral cortex and cells gradually die. The disease causes memory loss and things that were obvious before will be difficult for the sufferer. Alzheimer's disease also affects next of kin to a large degree; they will have to take a great responsibility. The next of kin are entitled to support from healthcare.Aim:The aim was to highlight next of kin' experiences of healthcare to their family members with Alzheimer's disease.Method: The study was based on narratives, which in this case means analysis of autobiographies.

 Background and aim: Media development and digitalization has expanded the PR industry's working area. More participants are on the media market and it is becoming more and more difficult to define what PR really is and what the PR agencies/departments really do. Is PR marketing, information, event marketing or maybe propaganda? We believe that the complexity to define the term PR can lead to a loss of critical approach to the business, especially among young people. Has the PR industry managed to eliminate their negative image among students in upper secondary school and what do they associate with PR today? The aim of this essay is to examine what a selection of students associate with the term PR and if they are critical to the PR industry or not.Method/Material: The method is a quantitative survey.

Background: Breast cancer is one of the most common types of cancer in the world and it usually affects elderly women. However, there are between 600-700 cases per year in Sweden where women under the age of 45 are diagnosed. Removal of the breast or part of the breast, hair loss, fatigue and nausea as a result of the breast cancer treatment has an emotional and physical impact on the women?s lifeworld. The nurse should build a relationship with the women to identify and meet their needs. Aim: To describe younger women?s experiences of getting a breast cancer diagnosis and life afterwards.Method: Four biographical books were analyzed to match the aim of the study.Result: The findings were that the women experience similar thoughts and feelings when it comes to living with a cancer diagnosis.

The object with the study of this literature was to describe differente programs of care and patients and relatives experience and opinion about the caring for patients with Anorexia Nervosa. The method the author used was a descriptive literature study based on imperial studies. The studies were based on 15 scientific articles within the chosen field. The results shows that these patients hade special needs to be seen and heard as individuals, involved in their own treatment, and have good contact with the caring staff. The study also shows which methods were mostly appreciated involving nurses, patients and relatives.

Many of us have grown up hearing or using words meant as insults or negative adjectives that were in fact names for social groups. Most of them have gone unquestioned in the mainstream consciousness, but the term Gay in the generally negative meaning has in the past years been given attention as offensive and homophobic, with debates emerging in response over whether or not this is true, particularly on the internet. It is the articles and forum threads from these debates that make out the empirical material for a qualitative study as I ask what these people?s thoughts are about this term and how it is perceived.After a qualitative coding and analysis of these texts, and interpretation of the results based on Erving Goffman?s theory of Phantom acceptance and stigma terms, Judith Butler?s theory of performativity, Ferdinand de Sassure?s theory of signifier and signified and how it connects to the community and Baudrillards theory of simulacra, this is the principal conclusion that I have drawn:For some of the people in this debate, the term Gay and its use is about homophobia and heterosexism, though mostly it?s not overt but a subconscious part of the continued dehumanization and stigmatization of homo- and bisexual people. This is a position I callThe socially focused skepticism.

Personalnedskärningar är ett resultat av det pågående oroliga arbetsmarknadsläget. Flera aktörer jobbar idag med servicetjänsten omställning vilket är en hjälp för arbetsgivare att hantera nedskärningar och övertalighet genom att få uppsagda medarbetare att komma vidare i ny sysselsättning. Trots en lågkonjunktur har omställningsarbetet visat på uppnådda lyckade resultat. Studien undersöker och sammanställer individers upplevelse av att genomgå ett omställningsprogram samt undersöker vilka faktorer som har betydelse för individers hantering av stressen i denna påfrestande arbetslivsrelaterad förändring. Tillämpningen av problemfokuserad coping undersöktes bland 71 deltagare som genomgått omställning i antingen kommunal eller privat sektor. Resultatet visade att deltagarna tillämpade problemfokuserad coping i relativt lika stor utsträckning oavsett yrkessektor.

Mechanical harvesting may result in timber damages leading to reduced saw log quality. The initiator of this study was VIDA ? a privately owned concern operating in the value-adding process industry of forest raw materials. The aim of this study was to examine the type and amount of damages on Alvestakubb caused by the harvester head during the cutting process. The aim was also to compare the damages caused by different types of feed rollers and to evaluate the effects of temperature on damage occurrence.

Denna rapport är ett resultat av ett examensarbete på civilingenjörsprogrammet Teknisk design, vid Luleå tekniska universitet (Ltu). Uppdraget i examensarbetet var att utveckla ett virtuellt koncept för integrerad stubbskörd och trädfällning åt Iggesund Forest AB/Olofsfors AB. I dagsläget sker trädfällningen och stubbskörden genom två separata operationer. Intresset för stubbskörd och skogens totala biomassauttag har idag ökat för att klara av de nya uppsatta EU målen med krav om att minst 20 procent av dagens energianvändning skall komma från förnyelsebara energikällor till år 2020, där skogen utgör en av de största förnyelsebara källorna. De stubblyftningsmetoder som används idag är inte helt optimala och effektiva för att det ska vara kostnadseffektivt att ta hand om stubbarna.En förstudie med en grundlig benchmarking gjordes över de olika stubblyftningsmetoder som används idag för att ta reda på och undersöka vad som fungerar bra respektive mindre bra med dem.

The aim of this work is to develop new conceptual designs for the fairings that are situated between the fin and the rear fuselage on the new version of the JAS 39 Gripen aircraft, called the Gripen E/F. The designs presented should show a profit in the form of lower weight. To achieve weight loss, the possibilities of using other construction materials other than those which are available at Saab today were studied. Therefore, a material survey was carried out in which the market for modern construction materials was studied to get an idea of today?s level of technology.

This is a qualitative study, whose purpose is to examine if night shelters effects homeless peoples self-perceived psychosocial health. In Sweden alone there are almost 18000 homeless people, and 12% of them uses a night shelter. The homeless can?t be seen as a heterogeneous group but instead homelessness counts as a state of being in. The Swedish National Board of Health and Welfare have done mapping over the homelessness since 1993 and the problem is an important part of what the welfare system has to fight against.

The aim of this literature review was to elucidate how suicidal and self-harming patients should be treated and cared for, mainly in the acute phase in somatic care. Searches were conducted in databases with relevant keywords. Qualitative and quantitative articles were included, would not be more than 20 years, be written in Swedish or English, and match the aim of the study. Results showed that nurses and patients felt that the treatment would be respectful, non-judgmental and characterized by active listening and clear communication. Poor care was described as disrespect and lack of understanding.

Since the mid 60?s, Germany has seen dropping fertility rates and yet next to nothinghas been done to combat this trend until the current regime led by Angela Merkel andher minister of family affairs, Ursula von der Leyen initiated a number ofcomprehensive reforms of Germany?s family policies.Family policy in Germany is being reformed in three ways. First of all parents arenow eligible to receive substantial financial support in order to compensate the loss ofincome associated with a pregnancy and or parental leave. Second, the all but nonexistentpublic child care services are being vastly expanded with the goal of beingable to offer child care service for every child age 0-3. Thirdly the tradition of schoolsending classes midday is being reformed with the aim of letting kids stay in schoolmuch longer thus enabling parents to work full-time as opposed to part-time in orderto be able to take care of kids returning from school.The hopes for these ambitious reforms are tremendous.

The concept of a Sharia compliant financial system has been a frequently discussed topic among scholars, bankers and media since the 1960th. It origins from the prohibition of interest, riba, which is stated in the Quran. Islamic banking is spread across the Muslim world and also exists in some western countries. This paper will try to create an image of what Islamic banking is in theory and in practice. This will be done by looking into the different methods of interest free banking, the Quran and the annual reports of four Islamic banks in different countries.
