Underso?kning av tryckfall relaterat till avstånd mellan två 90 graders kro?kar i cirkula?r ventilationskanal
Due to higher standards of living around the world, greater industries and larger infrastructures causes an increase of the global energy consumption. This harvest of energy puts a great stress on the global environment. With this development, it becomes increasingly important to utilize energy resources in the best possible way.Fans are components that are often used in the industry and in households. A common problem is that the fan is oversized. An oversized fan causes an excessive flow, which has to be adjusted in order to achieve the correct flow.
Hur inverkar olika andel vallfoder i utfodringen på produktion, hälsa och beteende hos mjölkkor? :
Cows are ruminants and they need fibers in their feed and sufficient eating time to function psychologically and physiologically. Many of our cows don?t get enough forage and too much concentrates, which given in the wrong way may cause health and behavior problems. Too much concentrates at once makes the pH in the rumen sink and this may cause decreased fiber utilization since the microbes in the rumen are negatively affected by this. The cow may also get serious problems such as laminitis and abomasal dislocation.

Att leva som konstnär : En studie om värmländska bild- och formkonstnärers arbetsvillkor
The purpose of this bachelor thesis was to illuminate and analyze the working conditions of visual artists in the Swedish region of Värmland. As a profession which is known to have many problems concerning income and the fact that most artist are unable to get by on their art sales alone it becomes interesting to look closer on cultural policy?s affecting the artists, where the problems lie and what possible help they can get.I have used previous research and different sources to map out the working conditions in Sweden and Värmland alike and also interviewed five different visual artists in Värmland to get a general view of the working conditions in the country as a whole and their perception of the situation and special circumstances in Värmland. I have also used discourse analysis to compare the source material with the answers of my respondents to see which discourses that exists, that have hegemony, and to see how this subject is talked about.The results of this study showed how political decisions may force artists to become self-employed entrepreneurs even though many artists do not self-identify as such or even have any interest in profitable gain. The study also shows among other things that most artists have another occupation on the side but that there are some aids to help the artists with income.
Samverkan eller motverkan? En studie om myndighetssamverkans konsekvenser för rättssäkerheten och barnperspektivet
Children that are taken care of for institutional care by the social services are unprivileged as a group. When society takes over the parenting role, it forces local governments and other accountable authorities to guarantee these children satisfactory support and good care according to each child's needs. The aim of this thesis is to analyze and discuss problems with implementation in policy processes when authorities incorporate. From the normative standpoint of legal security and the United Nations Children's Convention, this thesis investigates the consequences of interaction between two Swedish supervisory authorities for the social services: Socialstyrelsen and länsstyrelserna. To fulfill the aim I will investigate the approach taken by the authorities and the work division between Socialstyrelsen and länsstyrelserna.

Plafondmålningar - Arkitektförbundet Måleri på duk, Skadefenomen och åtgärdsproblematik
The concept of large paintings includes panoramas, cycloramas and other paintings thatin size exceeds the normal magnitude of wall hung paintings. When these large paintingsare mounted in the ceiling, they are referred to as plafonds. When they are performedon canvas, certain kinds of structural distortions and stress occurs. In addition, becauseof their size and mounting high up in the ceiling, plafond paintings are often difficult tohandle, which leads to less or no maintenance. A plafond may therefore be left withoutattendance for many decades.This thesis has its focus on what happens with plafond paintings on canvas when they areexposed to gravitational forces, and the problems involved in restoring large paintingsmounted in the ceiling.

Beskattning av skalbolagstransaktioner : Analys av skalbolagsreglerna ur ett tillämpnings- och rättssäkerhetsperspektiv
Shell companies are characterized by containing liquid assets such as cash, securities or other similar assets. Transactions of shell companies constitutes a severe problem since the purchaser often has the aim of obtaining undue tax advantages by not paying the tax debt of the company.Historically it has been complicated for the legislator to stop the set-up in an efficient way since the transactions as such are not illegal, instead rather commonly used for example to restructure companies or for the transfer of companies to the younger generation. The purpose of the current legislation is to prevent individuals and corporations to involve in shell company trade. Aiming for an efficient legislation, the tax rate is at a very high level.The issue with the rules is that also honest buyers are at risk of being covered. This calls for high demands in complying with the principle of legal certainty and the possibility to forecast the tax consequences.The purpose of the thesis is to identify and analyze eventual problems when applying the legislation.
Att skola mångfalden ? ett nationalistiskt försök : En analys av sverigedemokraternas diskurs om det goda samhället och den goda skolan kopplat till skolansvärdegrund
This essay attempts to examine the discourse of the Sweden democrats in relation to thevalue system of the Swedish national school.To analyse the political texts I use discourse analysis and especially the method and approachconducted by Judith Lee Bacchi. Bacchi focuses on the construction of a problem in variouspolitical discourses. When performing this kind of analysis the main question is (accordingto Bacchi): ?What is the problem represented to be??I find that the Sweden democrats construct the ?migration politics? and the ?multiculturalpolitics? that is guiding the society as the cause of most problems in our society. To solvethe ?problems? they promote a nationalistic and a cultural racist discourse especiallypinpointing the ?Muslims? as being a problem.Since the Sweden democrats are striving to implement their discourse in the society andschool, and since their discourse already are reproduced by solar students in the classroom,I find it important to examine the essence of their particular discourse and contrast it withthe current value system of the Swedish schools.I don´t find the nationalistic and racist discourse of the Sweden democrats to correspond tothe value system of the Swedish school, mainly due to their strive to create alienation, andby labeling individuals in a reductive manner, instead of using apparent differences as asource for democratic discussions in the classroom.
Mind the gap : En studie om samarbetet mellan entreprenörer och affärsänglar
Today there are a number of different financing options but few of them are suitable for start-up companies. Business angels are in that case an exception and a suitable investor in these companies. Business angels are individuals who invest in young companies and differ from other financiers in the sense that the collaboration with the company is closer. Business angels are although few in numbers while the young companies often tend to be in most need of funding and has the greatest potential to grow.The purpose of this study is to gain a deeper understanding of the cooperation between entrepreneurs and business angels and to identify which effects the financial gap have on these financial associations.Business angels and entrepreneurs collaboration are hard to interpret and therefore demanded a deeper examination. We thus used a qualitative method consisting of six different interviews in three different cases.The study shows that established collaborations between entrepreneurs and business angel?s seem to be affected by the financial gap to a great extent, which has been expressed in negative consequences.
Mean value modelling of a poppet valve EGR-system
Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model.
