Passivhusen på Oxtorget
Syftet med vårt examensarbete är att undersöka hur passivhus eller så kallade nollenergihus skiljer sig i funktion samt uppbyggnad från konventionella hus.I vår undersökning tar vi upp hur utformning, orientering, material samt ett väl fungerande klimatskal påverkar energiförbrukningen.Vi har tittat närmare på faktorer som sparar energi samt hur ett typiskt passivhus är uppbyggt. För att se hur teorin fungerar i praktiken har vi tittat närmare på befintliga passivhus, nämligen de på Oxtorget i Värnamo.Vi har kommit fram till att passivhus fungerar och vi anser det som väldigt viktigt att man fortsätter driva fram arbetet och informera om dess betydelse för miljön.Passivhus blir mer och mer uppmärksammat. De är något dyrare att bygga, men man tjänar in det i längden. Lönsamheten är dock inte det viktigaste utan känslan av att man gör något bra för miljön..
"Det finns inget bättre än en lärare som verkligen bryr sig om dig" : En studie om vad som gör gymnasieelever studiemotiverade ur elevens perspektiv
My purpose for this essay is to examine what factors are considered to have high influence on motivation to study and what measures can be taken to enhance student?s motivation to study from a student perspective. The main source of theory for this study has been the classification of motivational factors that has been based on Herzberg?s twofactortheory with complementary theoretical sources. The study is based around two research methods, one survey together with complementary student interviews. The empirical material consists of 118 completed surveys together with nine student interviews. The study?s results have found that students find the main source of rising motivational level originates from the professional role of the teacher. Additionally the students find the main source of subsiding motivational level originate from rising level of stress and uninspiring teachers.
Går Sverige mot en mer hållbar energianvändning?
Sambandet mellan samhällsutvecklingen och de växande miljöproblemen kom i
slutet av 1980-talet att få en allt mer framskjuten roll på den politiska
agendan i Sverige. I och med att energianvändningen står för en stor del av
miljöproblemen har allt fler kommit att inse vikten av att uppnå en hållbar
situation för energianvändandet. För att se hur arbetet mot en hållbar
energianvändning fortskrider har International Atomic Energy Agency (IAEA)
tagit fram en modell för detta. Studiens övergripande syfte har varit att
analysera huruvida Sverige går mot en mer hållbar energianvändning med
hjälp av IAEA:s indikatorer. Teorin i studien har baserats på grundläggande
miljöekonomiska resonemang.
Analys och beräkning av emissionsfaktorer för växthusgaser
An increased awareness about the global warming has created a demand for more information on how the climate is affected by different activities.This master thesis was initiated by Tricorona, a Swedish company that offers its customers analysis and calculation of their climate impact. Tricorona also supplies climate neutralisation with CERs, in accordance with the Kyoto protocol and controlled by the UN. This work demands updated emission factors for greenhouse gases. An emission factor gives information about the greenhouse gasintensity of a service or a product [kg CO2-eq./ functional unit].The purpose of this thesis is to examine how electricity, district heating, hotels, taxis, food and materials affect the climate and how emission factors for these areas can be calculated.This was done by reviewing and comparing different studies and by interviewing experts. The information was evaluated and recommendations on calculations and emission factors were made.The consumption of energy is the main source of greenhouse gas emissions for district heating, electricity, hotels, taxis and materials.
Vi har alltid utmaningar på HR - nuvarande upplevelser och framtida behov vid användandet av IT-personalsystem
The aim of this thesis was to investigate how the use of the IT-personnelsystem influences human resources and the new challenges and future requirements that may occur, while IT-personnelsystem is used more extensively in the HR-function.Previous research referred to in this study, has focused on how the HR-transformation has contributed to the development of an IT-personnelsystem, which has been used with increasing frequency. This use has created a significant change in the HR-function. This thesis focuses on investigating, describing and analyzing how the practice and development of the IT-personnelsystem meets the needs of the HR-transformation.This study uses qualitative research methods to investigate sixteen users? experiences and our understanding and conclusion is based on both semi-structured interviews and webb surveys. Initially deductive, later on our study took a more abductive approach.The result indicated a variety of uses for a specific IT-personnelsystem dependent on the users? function and positions and also how HR-activity was organized within the business.

Den etniska segregationens två dimensioner. Fritt val eller stigmatisering av etniska grupper? -en diskursiv studie om etnisk boendesegregation från 70-tal till idag
In what way has the ethnic housing segregation changed from the 1970´s until today and has the politics concerning these matters dealt with the ethnic segregation as a phenomenon that occur due to free choices of ethnic groups or as a stigmatization and marginalization of ethnic groups? To be able to find out what actual changes there are to be seen in the political measures regarding the ethnic housing segregation from the 70´s until today, I have made a discoursive investigation of some of the states official investigations from each of the decades. I chose to focus on a qualitative analysis and my theoretical framework consists of theories considering grouprights as well as structural and cultural explanations.I realize that the changes have been proportionately high retorically, but the actual changes have not been that obvious. I find a retorical development that has changed from the idea of the great impact of the immigrant in the ethnic segregation process, at the same time as huge differences between groups emerge, to establish a gap between us an them and a stigmatization of ethnic groups. The development somehow seems to have reconnected to the first stage.
Vilken omvårdnad får den polikliniska patienten vid cytostatikabehandling för att uppleva livskvalitet
Every year an avorage of 40 000 Swedes fall ill with different forms of cancer.
Chemotheraphy has an effect on the tumour cells as well as the healthy cells in
the body, this causes many side effects which can be very problematic for the
patient. The study was carried out in order to indicate the care measures that
are taken to deal with the side effects i. e stomatit, loss of hair and
sickness/vomiting, that are connected with chemotheraphy so that the
outpatients will experience a quality of life. The method used was a
qualitative interview with six nurses from the South if Sweden, all of whom are
working with chemotheraphy patients.
Fodersammansättningens betydelse för tillväxt hos häst :
The aim of the present study was to investigate the effect on growth of foals on two different diets, either a forage-based diet or a diet containing approx. 40 % concentrate. The report also includes a review of the pertinent literature on the effects of diet on mares? milk and growth of horses. The hypothesis of the study was that a forage based diet will result in a similar growth pattern as a diet including more concentrates if the diets contain the same amount of energy, crude protein, lysine, calcium and phosphorous.

Utveckling och psychometrisk testning av "Pain Impact Inventory" - en jämförelse mellan två olika ansatser
The aim of this study was to develop and psychometrically evaluate an instrument for measuring the impact from chronic pain on daily life. Traditionally psychometric evaluation is done with parametric methods even if the items are ordinal data. In this study the instrument to be developed is solely based on ordinal data, and the psychometrically evaluation is done with both traditional methods (i.e. parametric statistics) as well as with non-parametric methods. These two different ways of psychometrically evaluation are then compared with each other.
Sekundärnät för lågtempererad fjärrvärme
Lower energy use in buildings is a result of increasingly stringent energy requirements across Europe. When conventional district heating technology is used in areas with low energy consumption heatlosses do not fall even though the amount of energy delivered is reduced. This reduces income for thedistrict heating company. To maintain their economic viability the district heating companies? majorchallenge is to implement new solutions that minimize heat loss.
Undersökning av solcellspotentialen för golfverksamheter i Sverige
Photovoltaic Systems in Sweden has longbeen heavily dependent on subsidies and grants to bring in a profit for the investor. Production of excess electricity is a major reason for this as the compensation for excess electricity today is low. However, there are businesses that have an electricityneed that are particularly suitable for solar electricity. These businesses have an electricity demand when the sun shines the brightest and if the Photovoltaic System is properly scaled, the excess electricity can be minimized. A golf club is that kind of a business and this thesis aims to examinate the solar power potential for golf businesses in Sweden.Nine golf clubs was selected from different locations in Sweden.
Utvärdering av Near Field Communication och Certified Wireless USB : Säkerhet vid utveckling av applikationer
Today?s society is one where technological advances are made daily, which increases the need to stop and assess the risks against users? integrity when integrating new technology in contemporary systems all the greater. We have taken two technologies, Near Field Communication and Certified Wireless USB, whose envisioned area of use is to be integrated into mobile phones, and evaluated what security threats are revealed for the respective technologies. The threats against security have been identified through research of the standards and existing reports for each technology. Practical experiments have not been conducted on account of us not having access to any equipment to run such trials.
