Vitvarueffektivisering med hjälp av värmelagring : Simuleringsstudie kring energiförsörjning av vitvaror med hjälp av värmepump & ackumulatortank
The constant need of energy is something that affects us all no matter our current situation. Whether we are driving our car to work, taking the elevator or using the oven to cook dinner we end up relying on energy. Our whole society is continuously striving to achieve a higher grade of efficiency and the process of supplying ourselves with energy is no exception. The importance of appliances in our everyday life cannot be exaggerated and thus the importance of their high efficiency.Efficiency is already a keyword in the appliance industry with labels, stars and numbers helping us choosing the most suitable option for the task ahead. No matter how efficient appliances often use pure electricity as their energy source.
"I världen, men icke av världen" : Konstruktionen av kristen manlighet i Skånes Missionssällskap ca 1939-1945
The aim of this study is to analyze the construction of "Christian masculinity" during the modern era. This is made in opposition to earlier research that has claimed that masculinity could not be constructed religiously, that is, without at the same time being constructed as effeminate or anti-masculine.Using a wide variety of theoretical concepts - such as discourse analysis, class, secularisation, masculinity as constructed from countertypes, and finally masculinity as a homosocial construction - I analyze a free church in Sweden, the Scanian Missionary Society (Skånes Missionssällskap), during the period of ca 1939-1945 (the society was a district of the Swedish Covenant Church, or Svenska Missionsförbundet), in order to argue for the standpoint that masculinity, in fact, could be constructed religiously. The primary source is the society's weekly journal Sydposten.The main results in this study can be summarized as follows: 1) The leading men in the Scanian Missionary Society did, in fact, construct a Christian masculinity, i. e. a masculinity whose core values and ideals were Christian, e.g.

The report even includes the connection between components by cable wiring, isolation, grounding, fuses and shaping of metal goods.As the cabinet also communicates with a computer, the report includes the solution of the data communication using the software iTools from Eurotherm. The communication part includes information about a converter that converts EIA422 to USB.The cabinet was produced at a company, called VG Scienta, in Uppsala during the spring 2010.
Lysande rör, rörligt ideal : belysningsbranschens introducerande av lysröret i Sverige
During the 1930´s the hot potato for the Swedish lighting associations were how to create the most suitable light for every situation, either for industries, offices or homes. The light bulb were the most frequently used source of light but due to limitied luminous intensity, big halls sometimes required up to hundreds of light bulbs to produce the right amount of light. Two kinds of different lights, by different reasons, can be titled the predecessors of the fluorescent lighting during the 1930´s: The volfram-filament tube light due to its estetic similarities and the electric discharge (mercury- and sodium-) lamps due to its technical resemblance. Even though they came in quite wide use (the volfram tube in public halls (e. g.
Individers erfarenheter av hur migrän påverkar det dagliga livet : En litteraturöversikt
BackgroundMigraine is a comprehensive endemic disease who is affecting both women and men, but with higher prevalence among women because of hormonal factors. Risk factors for the disease are female gender, hereditariness, depression and socio-economic factors. Migraine can be triggered by factors like stress, menstruation, irregular routines for sleep and unbalanced meals and diet. Migraine is a condition that causes a big suffering for the affected individuals.AimThe aim of this study was to describe individuals' experiences of how migraine is affecting the daily life, out of the aspects like working life, family life and social life.MethodA literature overview was maintained, and eight qualitative studies and two quantitative studies between the years 2003- 2014 were analyzed.ResultsThe analysis of the articles lead to one main theme; "Guilt, compensating and restrictions" and seven subthemes "Not being able to perform their best", "Met with incomprehension", "Not being able to take care of home and children", "Not enough", "Avoiding activities", "Always be prepared" and "Living with restrictions".ConclusionMigraine is affecting the daily life among these individuals in a great extent. The disease makes it hard to perform well at work.
Att läsa eller inte läsa en "guideline" : En aktionsforskningsstudie angående externa riktlinjer i ett interaktionsdesignprojekt
As part of an Agile developing team I have in my role as interaction designer also tried to evaluate the ?iPhone Human Interface Guidelines?. With action research I have taken actions to change the workflow and to see what there can be done to make the guidelines more motivating to use. Action 1 tried to make the iPhone components more available and it suceeded, action 2 tried to make the guideline more available in whole and did not work as it was designed to do. The guidelines did not work as a source of inspiriation and I and my fellow designer distanciated us from it.
En topologisk representation av en polygon;det rakkantiga skelettet
The aim of this thesis project is to produce an algorithm for finding a topologicalrepresentation of a polygon, called a straight skeleton, using floating pointarithmetic. Various straight skeleton algorithms are examined and discussed witha focus on time complexity and one is chosen for implementation. This implementationis then compared with the open source library CGAL with regards torunning time. The result is an algorithm which is based on an algorithm by Felkeland Obdrzalek and which, for polygons with more than five thousand vertices andthree significant digits representing points, runs around 25% faster than CGALsimplementation. Complications regarding the use of floating-point arithmetic arealso discussed..
Don't be blinded by the words : En uppsats om att kommunicera med hjälp av fotografier
Following study is about the anorexic behavior and the pro-ana movement, which is a web-based subculture where the followers of this, stands for anorexia as an identity position and lifestyle, rather than a disease. The purpose of this study was that, from a sociological perspective give possible interpretations of the anorexic behavior, and interpret why some anorexics choose to be a part of and identify oneself with the pro-ana movement. The reason has been to conduce more knowledge and understanding of the topics, but also to contribute with a deeper perspective and sociological approach to the former research that is already available.To conduct the study, qualitative research has been used, and the chosen methodology was document analysis/text analysis. The collected empirical data consisted material from two pro-ana forums, four blogs and six twitter accounts, where all the users of those claimed to be supporters of the pro-ana. The empirical data has been interpreted by Howard S.
Systemlösningar för plus- eller passivhus : En studie med syftet att lösa energibehovet för ett specifikt hus.
The purpose of the house which is the basis of this report is to be able present itself on the market as a relatively cheap and at the same time a climate friendly choice. The house is supposed to be able to be built anywhere in Sweden and the rest of Scandinavia in a short period of time. This puts demand on what kind of heating system the house can have, since not all places have the geographic advantage of being able to use geothermal or district heating. Therefore the heating system choices will only include those that are not limited by their geographic location. The house will be built in modules which only require the groundwork to be done before the house can be erected. In this report "System solutions for plus or passive-housing" a comprehensive literature search has been conducted as well as a number of calculations.
Svenska livsmedel - varför? : restaurangers, grossisters och offentlig upphandlares inställning till livsmedel från Sverige
The background of this research is that Swedish food products have hard to compete at the home market, depending on imported food products that increase more and more for every year that pass by. The ethic values LRF associate with Swedish food products, many customers have hard to put in relation with condition of foreign agriculture.
Most customers today inquire high quality, safety and convenience in the food which they are eating. The source of their food seems to have less meaning. Many restaurants and bigger households appreciate Swedish food products and wants to buy them but price differences against foreign wares are to high.
We have done oral interviews with wholesale dealers, restaurants, public purchasers and with different market organisations, there we have discussed buying strategies, the way they see the primary producer, the conscious of guests, choice and attitudes to Swedish and foreign products, distribution of power in the food market chain and to what position and suspension, they want the ranks of suppliers to have.
The result shows the share of imported wares within restaurants and bigger households are at a high level and will continuing increasing. Within these sectors the final consumer in many cases put less effort in the origin of the raw source of food.
Rumslig utbredning av tuberkulos : Stockholms kommun år 2002-2011
This bachelor thesis is written as a part of the geography program at Stockholm University, Sweden, and the study was conducted from April to June 2012.Tuberculosis (TB) is an airborne disease and one of the most widespread infectious diseases in the world with more than nine million new cases each year (SMI 2012, digital source). The disease is a major source of death and suffering in many places and the number of deaths remains high despite the availability of highly efficacious treatment. To control and prevent further spread of TB, the mapping of the disease spatial distribution is of essential importance.In this study, maps were produced that shows the spatial distribution of TB between the years 2002 to 2011 in the municipality of Stockholm. These maps allow an analysis of the spatial distribution at a local scale over time.The aim of this paper is to study how the spatial distribution of TB has looked like in the municipality of Stockholm the last 10 years and to analyze why the spatial distribution of the disease looked like it did. This study is based on the hypothesis ?drift?.
Faderskapsanalys av tallfrö från Västerhus fröplantage : Skillnad i pollenkontaminering mellan öppen pollinering och pollinering inom ett avgränsat system
In this study, pollen contamination (measured by the number of seeds pollinated by pollen not belonging to any of the clones on the seed orchard) is compared between open pollination and isolated pollination environments in a Scots pine (Pinus sylvestris) seed orchard called Västerhus, located outside Önsköldsvik. In this seed orchard a tent experiment is taking place. Skogforsk has built six large tents covering 12-14 trees with each tent. Fertilization patterns were compared between one tree in a tent with a supplementation of pollen from five clones not represented in the tent and another tree of the same clone subject to open pollination outside the tents. By using DNA markers the paternity was determined for 48 seeds from each tree.
