Gröna tak för hållbar utveckling

Det är många faktorer som bestämmer val av tak i olika situationer idag. Den största frågan som uppstår handlar oftast om kostnaden. I intervjuer och studier har en sammanställning gjorts som beskriver alternativen grönt tak eller traditionella svarta tak på det nya badhuset i Umeå ur de tre hållbarhetsdimensionerna.Det extensiva gröna taket visar sig vara mer bullerdämpande, förbättrar luftkvaliteten i tätbefolkade och trånga städer. Det gröna taket har även en förmåga att ta upp ca 50 % av den årliga nederbörden. Något som gör det gröna taket mer hållbart ur ett miljömässigt perspektiv.

Investigation of tissue factor mRNA levels in human platelets using real-time PCR

Tissue factor (TF), a 47 kDa glycoprotein, is the initiator of the extrinsic pathway of blood coagulation and consequently of the upmost importance when damage to blood vessel occurs. The source of TF in circulation has been investigated. However, the source of TF is still not clear. One theory is that platelets express and increases the expression of TF after stimulation and the aim of our report was to investigate whether platelets really are a source for TF in circulation.Using specific primers for TF mRNA, platelets in plasma from healthy volunteers and from patients suffering from cardiac infarction were analyzed by using real-time polymerase chain reaction (PCR). Gel electrophoresis was performed after amplification of TF mRNA to verify the results.The samples were negative for TF when using real-time PCR and the few positive all had cycle threshold (Ct) values above 35.

Lärare - därför förkunnare : En undersökning av kristendomslärarinnan Astri Heimers morgonböner och hennes roll som morgonbönsförrättare 1938-1954

Unlike previous research, this thesis considers the possibility of regarding the morning prayers in Swedish schools as preaching, rather than teaching. 28 morning prayers, delivered in the church of S:t Johannes in the city of Malmö during 1939-1954 by the religious teacher Astri Heimer (1889-1986), constitutes the material for analysis. The purpose of this thesis is to examine if Heimer's morning prayers may be regarded as preaching, and to discuss the significance of this, in particular considering her role as leader of morning prayers.The examination is conducted in three steps. The first step investigates how morning prayers in general ought to be understood - as teaching or preaching? This is done by describing and comparing the literary genres of religious teaching and preaching, looking into the rules and principles which define the field of application.

Accountability: En studie av hur omfattande omgivningens krav är på ett företags ansvar i tid och rum vid en etisk skandal

Internet and media have led to companies' operations becoming more visible and transparent to the public during the 21st century. Several notable corporate scandals have led to society placing greater demands on businesses to assume more accountability for their actions. This study aims to examine and develop existing research regarding accountability, by adding dimensions of time and space. More specifically, the study examines the extent to which stakeholders hold corporations accountable after the revelation of an ethical corporate scandal, through a qualitative case study on a pending lawsuit against the Swedish corporation Boliden. Our theory is based on John Roberts' (1991) research presented in the article "The Possibilities of Accountability" and Martin Messner's (2009) research presented in the article "The Limits of Accountability".

Effektivitetsundersokning av medeltida kastmaskiner

Through the ages mankind has developed and tested a cascade of varying weapons ofwar, large and small, and has has striven to push these creations to the limits of theirtime. A grand example of this are the medieval siege engines that have changed shapeseveral times over the centuries. After all this time the eciency of these siege engineswill have reached their peek.

Har marknadsvärdering enligt IFRS ökat fastighetsbolagens finansiella risk?

The purpose of this Bachelor Thesis is to investigate whether the introduction of IFRS, and in particular IAS 40 regarding fair value accounting of investment property, has lead to increased financial risk for Swedish real estate companies. Financial risk is measured using several financial risk ratios during the period 2000-2009, effectively covering the period before and after the introduction in 2005. The financial risk is found to actually have decreased significantly in comparison with the control group. The relative decrease supports the notion of a factor unique to the real estate companies at least partially driving the change, possibly IAS 40. However, this change is, due to the statistic method employed, only an indication of the direction of change, and consequently interpretations of the magnitude of change cannot be made.

Bokförvaringsplats eller serviceinrättning? Direkt eller indirekt service på Göteborgs stadsbibliotek 1891-1960

This paper describes the development of direct and indirect service at the former Gothen­burg city library. This was during this period of time not the public library of the town, but a scientific library mostly serving the college, although also open to the public. Furthermore the services offered in Gothenburg are compared with those of the two old Swedish university libraries in Uppsala and Lund. The investigated direct serviceforms are "making material available", "guidance", and "localities". The indirect service areas are "the catalogue" and "the personnel and their competence".The conclusion is that the differences weren't that big and that Gothenburg city library was a modern library providing about the same services as you could find in Uppsala and Lund.

Användbarhet och turism, är det lätt att kombinera? : En studie om turismsajters användbarhet

In this essay we discuss the broad area of website usability from a tourism perspective. Our goal was to investigate the usability in smaller and bigger tourism websites. We have declared what website usability means and the importance of involving the users when designing a user interface. In a pilot study, we conducted three interviews with people who work with usability and then used the information we got to form questions to use in a focus group interview. In this focus group, we asked three people to assess two Swedish tourism websites, one bigger and one smaller, to find out if they were considered usable and if there was any difference in usability depending on the size of the site.

Värmesystemsutveckling

In cooperate with Asko Cylinda we have developed a new heat system too short the process time and reduce the energy consume in a dishwasher and still have it too be a class AAA. The environment and quality is important for the company too still be the number one on the market, If they want too keep that position the product developed of new innovations will be very important. The systems we have developed are more effective and reduce energy up too 25 %. The process time is reduced too less than two hours, from the today two and half-hour. The solutions are too heat up the rinse water and the dishwater at the same time, with a new heating system and it make are solutions unique and effective. Its good for the dish and the environment.

Sexköp och fiskmetaforer - En diskursanalys av prostitutionsdebatten 1993-2011

"A discourse analysis of the debate on prostitution 1993-2011" The aim of this essay is to investigate how prostitution is constructed in the debate. The analysis is based off debate articles from four of the biggest Swedish news papers. Articles from two periods of time has been chosen, 1993-1999 and 2008-2011. The specific periods were selected because they revolve around the Swedish ban on the purchase of sexual services in 1999, and when it was evaluated in 2008. With a constructivist aim based on gender research, the themes and subject positions of the debate are explored via discourse analysis.

Föreningar av det skenbart oförenliga : En analys av motsatser i Ellen Mattsons roman Poetens liv.

The aim of this study is to describe how reviews of literature in Bonniers litterära magasin and Expressen changed during the period 1964-2004. The investigation is based on 20 reviews of novels and short stories, which are analysed with a method described in Hellspong and Ledin (1997) and inspired by Halliday. The theoretical frame of the investigation is founded on critical discourse analysis (Fairclough 1992 & 2001) and Habermas´social theory of the public sphere.The investigation shows, among other things, that the reviews became shorter and easier to read in both paper during the period. The investigation also shows that the genre´s style, composition and contents are relatively stable, and that current ideologies in society have a tendency to be reflected in the reviewers´evaluation of the books. To generalize, the reviews thus developed from a poetic genre in 1964, to become political in the 1970s, academic in the 1980s, feminist in the 1990s and finally an intermedial genre in 2004..

Optimering av prestanda och utnyttjande av flertrådsteknik

The purpose of this thesis was to help the company Medius AB with optimization of selected parts in an existing system to minimize the execution time by implementing multithreading. The idea was to manipulate the code so that calculations could be executed at the same time. The main work in this thesis consisted of three optimizations. The first one was to reconstruct a big ?for-loop? so it would execute every loop's work in an own thread. The second optimization also was a reconstruct of a ?for-loop? so it could execute the work in different threads. The third and last optimization consisted of reconstructing a stored procedure on the database, so different parts of it each could be executed in an own thread to create data at the same time. To implement the optimizations Visual Basic .NET and its support for multithreading and connection-pools was used. The result of the optimizations meant that one of the modules could be executed more efficiently and it was 12 % faster. The other modules execution time was more efficient by 25 % faster. The meanings and requirements for this thesis are fulfilled by now letting the system make use of its resources in a better way..

Simulering av simulinkmodeller medExtended Kalman FilterTidsoptimering av integrering

Simulation of different systems can be done using a graphical model description of the system based on block diagrams. The simulation software Matlab/Simulink offers a lot of possibilities to describe a huge number of systems, which can be linear as well as nonlinear. The simulation using Matlab/Simulink is done by integration based on different kinds of numerical methods.When nonlinear Simulink-models are simulated, it is often interesting to apply a Kalman filter to handle the noise that may occur within the process as well as corrupting the measurement. However, application of such a filter leads to an extensive time-consumption despite using fast computers. The reason is that the existing Matlab functions are not constructed for time optimal evaluation.

Instagram, det nya galleriet : En undersökning av konstbetraktande i sociala medier, med utgångspunkt i Jesper Walderstens Instagramkonto

In my paper I adress the question of what happens in the relationship between the beholder, the artwork and the artist when they meet in the era of Web 2.0. The new smartphone based medium that I write about is Instagram. The artist i write about is the Swedish illustrator Jesper Waldersten. My purpose with this paper was to explore how the the beholder, pictures and artist relate to one another i relation to Instagram and how the interface of the smartphone and the app affect the beholder in these relationships. I also seek out to understand the difference between how Instagrams interface affect the beholder in comparison to the interface of the artists web page and his book.
