Glass has sophisticated front properties and are used as facades in high buildings. During cold periods, these glass facades could cause thermal discomfort, due to cold downdraught. Cold downdraught can be countered by placing heaters under glass surfaces. Nowadays technology offers highly insulating windows, which is why there is an interest to investigate the indoor climate with only underfloor heating. The research in this area is limited, and few empirical methods are available.

På bullriga arbetsplatser använder personal ofta hörselskydd med inbyggda högtalare för att lyssna på exempelvis musik i underhållningssyfte. Om användaren lyssnar på höga ljudnivåer under långa perioder kan bullerskador uppstå i dennes öron. Enligt lagstiftning måste nivån därför begränsas i förebyggande syfte.Bullernivån är ett genomsnitt av de ljudnivåer användaren exponerats för under en arbetsdag. Användaren måste vila öronen om gränsvärdet för bullernivån nås.Om man utnyttjar att det är ett genomsnitt kan användaren tillåtas lyssna på en hög ljudnivå under en begränsad tid för att sedan sänka den. Det går att bevara både säkerheten och lyssningsupplevelsen om en sänkning införs långsamt.Detta arbete beskriver hur en algoritm till en digital signalprocessor kan konstrueras för att reglera ljudnivån.Målsättningen var att algoritmen skulle skydda användarens hörsel utan att försämra lyssningsupplevelsen, och utan att förbruka mer energi än nödvändigt.I algoritmen ingick en prediktor som predikterar mängden buller användaren riskerar att utsättas för, om denne fortsätter lyssna på samma nivå.Långsamma sänkningar av ljudnivån kan då utföras i tid innan gränsvärdet nås.Det visade sig att algoritmen endast behövde ett fåtal samplingar per sekund för att skatta och reglera ljudnivån tillräckligt precist, vilket reducerade energiförbrukningen.Resultatet visar möjligheten att kombinera målen för säkerhet, lyssningsupplevelse och energieffektivitet i hörselskydd.Algoritmen implementerades inte på ett skarpt system.Den hade enbart tillgång till ljudsignalen användaren ämnade lyssna på i underhållningssyfte..

Emerging infectious diseases poses a great future threat, not only to humans but also to domestic animals and wildlife. Even though the majority of these infections only cause minor health problems, the relatively recent emergence of HIV clearly illustrates that the next major human pandemic may surface at any time. Regardless of what the name indicates, most emerging human pathogens are not believed to be recently evolved, but to have existed previously in the natural environment. Most emerging pathogens are zoonotic, i.e. able to infect animals besides humans.

Background: Sweden is a country where vitamin D deficiency seems to be common, partly because of its geographical position, which reduces the availability of UVB radiation, but also that people avoid sunlight due to increased skin cancer risk. Research shows that vitamin D plays an important role in the prevention of many diseases such as cancer as well as autoimmune and neuropsychiatric diseases.Vitamin D is a fat soluble pre-hormone and a collective name for closely related compounds which act as hormones after undergoing a transformation in the body.Humans can utilize vitamin D through diet and produce it in the body by exposing the skin to the sun. Previous observational studies and epidemiological studies have established a hypothesis that there seems to be an association between vitamin D supplementation and reduction of depressive symptoms.Objective: The aim of this study was to investigate if vitamin D supplements may decrease depressive symptoms.Methods: This work is organized as a literature review and article search is made in the database PubMed in January 2012. Keywords used were ?vitamin D and depression? and inclusion criteria were: randomized clinical trials, be conducted on humans, written in English.

Banks carry a great responsibility when it comes to the financial systems in our society. Disturbance in the credit system affects both lender and borrower. All financial institutions must therefore carefully estimate their risk exposure. This assessment enables them to cover themselves from losses with appropriate capital buffers as main guardian. In order to prevent bank crises and also to maintain financial stability in general, new regulations concerning analysis and preventive actions were introduced on the 1st of February 2007.

The economic situation in the Swedish agricultural industry is currently experiencing a development towards larger units. This progress occurs simultaneously as farmers in cooperation more frequently make investments to decrease risk exposure and to improve the financial result. The purpose with this thesis is to study which advantages and problems a group of farmers experience after a common investment in a small-scale seed production. The aim with this investment is to increase the level of vertical integration in their respective agricultural firms and the results will be analyzed from an economic point of view. At present, the farmers are all seed producers with considerable cultivation areas.

The Swedish early childhood system is considered among the best in the world, however, in spite of this, we feel that there exists a conflict between educators? and parents? expectations of ?a good preschool?. During our teacher education training we have observed many different preschools and almost in all of them we have listened to anecdotes about one or more conflicts arising between educators and parents and which we have been able to pinpoint toward differing expectations. After talking with a preschool director, who also perceives that expectations of the preschool aims sometimes differ, our idea brought us to conduct this investigation.In this study, we have investigated parents? expectations of preschool and compared them with educators? expectations.

AbstractEqual opportunities from an employer brand perspective- What does the future manpower inquire?Authors: Erik Frick & Niklas HalldénInstructor: Karin JonnergårdExaminer: Sarah PhilipsonBackgroundWe are living in a society that originates from a patriarchy founded many thousand years ago. This has put women in an inferior position in the labour market. To promote equal opportunities we argue for that companies can utilise employer brand. Employer brand is a new theoretic concept that is being used more frequently among scholars and companies.Presentation of the problem? Which role do equal opportunities play to attract potential manpower from an employer brand perspective?MethodOur method has a quantitative approach and we have choosen to carry out a survey.

Today there are many students with behavioral and developmental disorders in schools. One of these disorders is ADHD. The medical designation ADHD stands for Attention Deficit Hyperactivity Disorder. I have chosen to research how two students with ADHD can be included in a fifth grade classroom.This research paper addresses the issues surrounding the student?s day-to-day life with a focus on the classroom.

Aim: On the basis of the Swedish 2012 National Patient Survey and its open answers, study how patients experienced the quality of care during hospitalization in a surgical divisionMethod: In this study, 306 patients' responses was compiled and analyzed by qualitative content analysis and reported descriptively in running text.Results: The way patients were treated by staff was experienced by respondents mainly as positive. The staffs? courteous and sympathetic attitudes were appreciated. The food that was served was described as substandard, distasteful and dull. The cleanliness of the hospital departments were reported to be inadequate, particularly in washrooms.

The aim of the study was to examine which approach future social workers have regarding specific competence in the meeting with lesbian, gay, bisexual, transgender and queer clients. Previous research shows that LGBTQ people have a low confidence towards social services, police and courts and say they face discrimination and degrading treatment to a greater extent than the heterosexual population. Research shows that education and better skills of LGBTQ culture among professionals can change the situation.The essay is based on a model of cultural competence in working with sexual minorities and people with a transgender expression. The model defines the meaning of an LGBTQ perspective and is designed to improve social work with LGBTQ clients.The study is quantitative and empirical data consists of 203 survey responses from students with a long experience of the social work education. The analysis of the results is based on the cultural competence three principles; attitudes, knowledge and skills.

Abstract:This thesis work has been conducted at the Real Estate Department in Halmstad.The department consists of a construction/project management-unit and an operation/management-unit.Like many other towns in Sweden, Halmstad has had a long lasting problem with indoor environment. Not at least at their preschools.Today they are constructing from current building regulations. They have learned from negative experiences which have occurred in the indoor environment in older buildings.Focus is now on healthy materials, like low emission value, energy efficiency and optimization of the building, but still with soft parameters such as cleaning, interior and choice of materials.The fixtures is provides by the real estate department and the furnishings are provides by the children and youth administration. Together they are trying to provide a great indoor environment.I have, together with the real estate department and the children and youth administration of Halmstad, investigated how to provide a good indoor environment in the preschools with small funds.In my thesis there is one theoretical part with a questionnaire survey of how the preschool staff is experiencing their indoor environment to determine where the problems often start. And a practical part with measurements to try and come down to a result that analysis the cause of the problems and also to make sure that the ventilation systems are fulfilling projected values.The measurements and the questionnaire surveys was made at Lokes preschool in Frösakull, Askens preschool in Oskarström and Gullbrandstorps preschool.There were some differences between the staff-responses at the three different preschools.At Askens preschool they feel that the premises are cleaned poorly.At Gullbrandstorps preschool they feel that the indoor-air is bad because they can´t open the windows.

Housing construction very close to the lake Mälaren has become very popular today. One potential problem with these houses is the influence of the sea climate. Unprotected buildings are affected by strong winds and precipitation. So for that reason, it is very important to make an accurate climate investigation and use it for decision-making during the planning of the new settlement.It is very important with a good moisture protection regarding pelting rain, that is the combination of wind and rain. This is more important for buildings close to a lake, as this location normally means a higher exposure to wind.

I meet in my work as art teacher many students of different descent, were they, or their parents, have different school experience than the Swedish. This, in combination with therecent discussion after the Muhammad caricatures about the banning of images in Islamic religion, made me curious to study what art education in a Muslim country looked like. I went to visit the Maramra Egitim Köyü school in Istanbul, Turkey, and especially their art classesfrom grade five to eight, which are the same age of students that I have been working with thelast ten years. This was my first visit to Turkey.The question I ask is: What does the practice of Turkish art education look like, using the Marmara school as an example. Which discourses can I identify in the art teacher practice? What surprised me the most was the frequent visual exposure of the founder of the Turkishstate, Kemal Atatürk.

Scania is among the leading companies in the heavy vehicle industry. Scania also assemble engines for their trucks and buses, as well as to external marine and industrial applications. Wrongly assembled parts leads to quality problems, which makes it important to secure that the assembly is correct. To do this Design For Assembly (DFA) is used to describe how parts should become easier to assemble. Scania?s production unit for engine assembly has had a working method for DFA in the shape of a checklist, which is not used.
