Tillagning i mikrova?gsugn och dess effekt pa? livsmedel : en ja?mfo?relse med konventionell tillagning
Microwave is a time- efficient device for heating and reheating of foods. Despite the fact that its effects on foods have been evaluated during a long period of time, without any more negative effects shown compared to conventional cooking, one third of the Swedish
population believes (in 2010) it accounts for a higher loss of nutrition.
This literature review aim to compile studies regarding how food is affected by cooking in microwave, with respect to cooking losses, nutrition, secondary metabolites as well as sensory and textural aspects and compare it with conventional cooking.
The compilation shows that different combination of effect (W), time and amount of water during microwave cooking have different effects on foods. The contents of proteins, vitamin B and carbohydrates are generally higher after microwave cooking, while anti-nutritional substances are affected much less during conventional cooking. This also depends on if it is of animal or non-animal origin.
However, for the majority of nutrition values the differences are quite small.
Framtidens enbostadshus : Att bygga på höjden med minimerad bostadsarea utformat enligt framtida energikrav
Tomtmarkerna i urban bebyggelse blir allt mer attraktiva. En minskning avbyggnadsarean medger positiva ekonomiska effekter på markkostnaden dåtomtpriserna tenderar att bli allt högre i stadsmiljö. En stor del av totalkostnadenvid nyproduktionen av ett enbostadshus är tomtpriset. Framtidens enbostadshusbör utformas med ett begränsat tomtbehov samt uppfylla framtida energikrav. Examensarbetet har utförts i samarbete med småhustillverkaren Eksjöhus, vilkatill följd av de ökade markpriserna upplever en minskad efterfrågan förnyproduktion av småhus. Likt övriga hustillverkare står Eksjöhus också införuppfyllandet av framtida energikrav. Syftet med examensarbetet är att utforma framtidens enbostadshus, genom atteffektivisera tomtutnyttjandet och förbättra energiprestandan.
Let´s talk about sex: en studie av patienters uppfattning av samtal i samband med testning/smittspårning för sexuellt överförda infektioner med fokus på sexualitet
The aim of this study is to examine the patient's understanding of the counselling while testing for an STI. The method was an inquiry directed to patients at two receptions, where tests for STI are made, and on the Internet for patients who made a test within the last year. The study involves 95 participants, 39 answered the inquiry directly after the test. The main results show that most participants are positive to talk about their sexuality and sexual strategies with the personnel, irrespective of who takes the initiative to the counselling. Women are yet more negative then men to talk about their sexuality, even if the test is made voluntarily by the woman.
Is goat milk a better milk replacement to piglets, rat pups and foals than cow milk is?
AbstractOne opinion among people who are experienced in hand rearing newborn mammals is that goat milk is more suitable than cow milk if the young needs a milk replacer. The purpose of this literature review was to find out if there is scientific evidence that goat milk is a better milk replacer for piglets, rat pups and foals than cow milk. The milk is essential for the newborn animal, as its only source of nutrition until it has learned how to eat solid food. In this literature review, the composition of goat milk and cow milk is compared with the nutrient requirements after birth in piglets, rat pups and foals. The nutrient requirements and the milk composition are partly determined by the newborn mammals activity level and suckling frequency, which also is described.
Enegiutredning Hotell Princess
This report will show the energy usage of Hotel Princess in Sandviken, Sweden. When the hotel changed owner an examination of the hotels heating, ventilation and sanitary systems were done. The report showed flaws in the ventilation system, and is why the new owner wanted a closer look at the energy use of the hotel. The original building was built in the 1930s and two major extensions have been built, one in the 1950s and the most recent in the 1980s. An assumption made is that the building parts were built to the restrictions during the time. Activities on the hotel include sleep over, conference, night club, massage and swimming in the hotels pool section.
Energikartläggning och energieffektiviseringsåtgärder i Zoologen på Göteborgs Universitet
The question of excessive global energy use needs to be solved. All energy production and usage have negative environmental impacts, which are best solved by reducing energy consumption and by using energy more efficiently. A large part of the Swedish energy use is concentrated to the building sector and to reduce the total energy consumption real efforts need to be made to make buildings more energy efficient.The aim of this study was to investigate how energy is used in one of Göteborg University?s buildings and to find measures that can be taken to improve its energy efficiency. The chosen building Zoologen, is used for research and education.The main method of the study is computer simulations of the present building and of possible energy reducing measures to be made in the future.

Arbetsprocessen i Revit. En studie av arbetsprocessen i Revit Architecture vid skapande av förslag över ett nytt bostadsområde i Varberg
Arkitektkontoret Sweco Architects i Göteborg har tagit fram ett förslag för ett bostadsområde i Varberg, där Varbergs kommun var beställare. De föreslog att ett eget områdesförslag skulle tas fram i Revit Architecture utifrån de planbestämmelser som gäller i området. Som en fördjupning i detta arbete valdes att även studera arbetsprocessen i programmet samt hur denna process kan tidsoptimeras. Ett problem idag är att en sådan process kan vara tidskrävande och ineffektiv. Syftet med detta arbete var att finna idéer på hur processen kan effektiviseras och att utveckla kunskaperna om Revit.Som en inledning modellerades hur området ser ut idag i Revit utifrån en ritning skapad i AutoCAD.
Torkning av flis med restvärme : Metoder för att sänka återledningstemperaturen
The purpose of this study has been to evaluate whether a Low temperature bio-mass dryer could be integrated with the local district heating system in Malå. The aim is to increase the thermal efficiency of the cogeneration plant in Malå, by lowering the temperature of the cooling medium. Another benefit that comes from this is improved combustion efficiency at the power plant, since drying the fuel causes an Increase of the heating value.Simulations has been made in Excel, and with use of linear regression, to find out if it is profitable. Data for this purpose has been supplied by the power company Skellefteåkraft and furthermore SMHI.The result of the Calculations shows that a very efficient bio-mass dryer is needed, if yield of investments should be made possible. An Investment of 4,27 Mkr, in a dryer, could at a such criterium return 60000 kr/year, if the price of the biomass is 190kr/MWh.
Investeringskalkyl baserad på ett flerbostadshus energiprestanda
The aim of this study is to find a method to incorporate the energydemand of a building in the investment cost estimate.The study is based on an actual apartment block. The significant energyaspects are identified, and changed to more energy efficient options.These are then simulated using the energy calculation program VIP+.The calculated energy need is used in the investment cost estimate, andthe simulated alternatives are compared in regards to their economicalprofitability.Depending on the focus, different alternatives are the most advantageous.Since this study aims to show which alternative is the mosteconomically profitable, the annual profit is the parameter of mostimportance. This means that individual measuring of heating and hotwater use is the recommended change of the original house. A changeof the windows to new ones with a U-value of 1,0 as well as 0,8W/m2K also results in a positive change of the annual profit comparedto the original house..
Valutamarknadens effektivitet - En studie av växelkurser utifrån UIP med förväntningar
This essay discusses and evaluates the international currency market in regards to efficiency. To prove the theory that, the difference between expected and actual exchange rates is explained by the difference in expected and actual interest rates and the difference in expected and actual inflation between countries, a model was developed. This model was inspired by the paper of Sebastian Edwards (1982), and is based on three theories; UIP, IS/LM and the Efficient Markets Hypothesis. The model uses 16 regressions estimated from three pairs of curriencies: $/SEK, £/SEK and ?/SEK.

Syntes och struktur i SAB förr och nu: En studie av avdelningen för språkvetenskap genom den första, den fjärde och den sjunde upplagan
The aim of this masters thesis is to examine the synthesis and the structure of the main class for linguistics F in the Swedish classification system SAB. We want to find out whether F has developed towards a more faceted structure or not. Our theoretical perspective is based on fundamental principles for modern classification. To carry out our investigation the first, the fourth and the seventh edition of SAB is analysed and compared. The results of our study show that the main class F has become more faceted and therefore the possibilities to use synthesis have increased.
Virtuellt ledarskap i näringslivet: Hur affärssimulering kan skapa kompetens, samsyn, och ökad ekonomisk förståelse i en organisation
The purpose of this thesis has been to explore the topic of business simulation from a theoretical foundation in social constructivism and theories concerning leadership as the management of meaning. The most important findings are that business simulation can be used for strategical leadership by management to create a common vision in the organisation members, which affects their perception of the business and the decisions and actions they make, which in turn can lead to a more efficient organisation that becomes better at meeting set goals. This can be viewed in different ways from different theoretical viewpoints: as inducing targeted changes in mental models to create changes in decision making and actions; as a secondary socialization process where the vision of management is externalized as a business simulation that is in turn internalized by the organisation members that participate in the business simulation, or as a way to frame and define the reality of the organisational members which creates a shared reference point against which a feeling of organisation and direction can emerge. In the future, business simulations may become increasingly used by organizations to create a common vision or to communicate a new decision to the organization members..
Processer och metoder som möjliggör för en effektiv produktframtagning
The high level of competition and the rapidly growing technology development has created new challenges for today's businesses where they are forced to deliver more customized products at a lower price and a shorter time period. This places high demands on the companies' ability to design and develop better products in a more efficient way. In addition to developing products, the design process focuses on securing long-term success for the company by developing nourishing skills. However, to achieve an effective design process the companies must improve their ability to plan as well as use their knowledge base in a more efficient manner. Toyota's product development system is a critical component for companies to address challenges that they?re facing and offers a great potential to create significant competitive advantages.
