Framtagning av beräkningshjälpmedel för tvärkraftbelastade förband med förbindare av metall.

The governing set of regulations for structural engineering in Sweden used to be Boverket, BKR. However in the beginning of the 21st century a changeover to new regulations, the Eurocodes, started.The transition was completed in year 2011 when the Eurocodes became the mandatory design work policy for all countries within the European Union. The Eurocodes were implemented to simplify and remove potential barriers to trade that may exist when countries have different design rules.  Since the changeover it has been important for all construction companies to update their knowledge base and their design software.When comparing the two calculation processes they seem similar, but there are a couple of differences worth noting.  With the new regulations, engineers will find that the process when designing joints in timber structures has changed.  What used to be a fairly easy and straight forward calculation procedure has now become tedious and time consuming.The objective of this degree project is to present a product, a dimensioning tool that will help structural engineers when computing lateral load carrying joints in timber structures.The degree project is made up of two parts where the first part is the written report describing the background and theory behind load carrying computations. The second part of the project is the actual dimensioning tool which includes several worksheets in Microsoft Excel. The program treats single and double shear connections of the following:Nail jointsScrew jointsSteel plates (thick and thin types) The user can edit the following parameters:Type of plate/ number of shearsStrength class of timber membersMember and plate sizeType of fastenerDiameter of fastenerLength of fastenerYield moment of fastenerkmod and partial factors for design load carrying capacityThe dimensioning tool was created and developed in collaboration with structural engineers at the company Byggteknik AB.

Mastcellens roll vid atopisk dermatit hos hund

SAMMANFATTNINGDenna litteraturstudie har gjorts med syfte att utöka kunskapen om atopisk dermatit hos hund med fokus på mastcellens roll i immunopatogenesen. Atopisk dermatit är en relativt vanlig sjukdom som kan drabba alla hundar oavsett ras; den är oftast livslång och kräver visst arbete för att diagnosticera och behandla med gott resultat. Förutom att det är ett problem hos hundar, finns även ett nära samband med atopiska sjukdomar hos människa, och hundar fungerar som en bra modell för forskning på humansidan.Trots omfattande forskning, vet man fortfarande inte varför sjukdomen uppkommer. Många teorier finns kring den immunologiska bakgrunden, men stora delar är fortfarande okända. Att mastcellen spelar en nyckelroll är dock allmänt vedertaget.

Immunohistochemical detection of thymidine kinase 1 in canine mammary tumors and lymphomas

The dog has often served as a model animal for humans in scientific studies. This is due to the fact that dogs are susceptible to a wide range of diseases which also affect humans. One example is cancer, a condition that affects dogs as well as owners. Neoplastic diseases account for 18-23 % of all deaths in dogs (Bonnet et al., 2005 and Jagielski et al., 2002). Mammary tumor, or tumor of the breast, is the most common tumor form in intact dogs and women (Im et al., 2013). Mammary tumors originate in the udder, and are classified according to their histological characteristics.

Externa aktörer och transitionsstater En studie om EU som en inflytelserik aktör och transitionsstater på Västra Balkan

In this thesis I discuss about economical and political transition in countries that is consecutively being induced by influential external actors. Looking closer on the role of the EU as a dynamic transitional force, with the intention of examining to what extent the EU can pursuit its interest and modify the economical as well as the political structures of transition countries. With relations to four transition states on the Western Balkans, more precise Bosnia-Herzegovina, Croatia, Serbia-Montenegro and Macedonia (FYROM), I have examined the influential position of the EU. Another feature that is discussed is the approach of the EU and the cause of it in respect to the Western Balkans. Since the end of the crises in Kosovo the EU was given the leading roll in stabilizing and reconstructing the Western Balkans.

Solenergi : en lönsam investering för ett lantbruk?

A possible way to reduce pollution and slow down the process of global warming is to increase the usage of renewable energy sources. One of these renewable energy sources is solar power. With the aid of solar panels and solar cells the energy from the sun can be transformed into both heating and electricity. The requirement to use the sun in this fashion is a suitable surface, for example a big roof, an angle between 40-60 degrees and that the surface should be exposed to the south. Almost every farm meets these requirements.

Sangvinolent berättande : En studie av Yu Huas roman En handelsman i blod

The present MA thesis analyzes how body and blood functions as historical and narrative elements in Yu Hua's novel Chronicle of a Blood Merchant (1995). In the novel, the story and the plot can not be regarded as disparate items; the two levels of the text are tightly interwoven by what the thesis introduces as a sangvinolent narration. The term conceptualizes the use of blood as a structural element and the thrust of the text, in this case how the ability to sell blood is a prerequisite for the story and the plot.Close readings reveal the structural correlations between the blood-selling main-character Xu Sanguan in the plot on the one hand, and in the story on the other, which can be detected to have, inter alia, an effect on the temporality of the narrative. Themes linked to identity, belonging and survival (performativity, mimicry, reification and alienation) permeate the text. In the novel the body and bodily fluids are sacrificed in order to form and enforce perceptions of identity and societal roles.The rhetorical use of ?blood and tears? (Ch.

Revidering av rockdatabas

Svenskt Rockarkiv is an organization located in Hultsfred, Sweden. Its goal is to collect and document the history of Swedish rock music. The archive contains several types of documentation, such as audio recordings, photographs, posters, video recordings and books representing Swedish rock music history. In order to store information about the audio recordings in the archive, Svenskt Rockarkiv uses a SQL Server 2000 database and a client application written in Microsoft.NET C# and Windows Forms. The purpose of this degree project is to audit the database and windows client, since the organization has needs of new functionality.

Projektering av robotcell

Syftet med examensarbetet var att projektera en fysisk robotcell till Haldex i Landskrona, tillverkare av bromshävarmar, då det finns ett behov hos dem att effektivisera sin produktion för att kunna bibehålla konkurrenskraften och tillverkningen i Sverige. Bromshävarmen är en mogen produkt vilket medför att det inte skulle bli lönsamt att omforma den utan istället fokusera på tillverkningen. Därför vore lösningen att automatisera den del av monteringslinan som inte tillför något värde till slutprodukten. Robotcellen kommer att placeras på bromshävarmarnas monteringslina som en automatiserad station vilken ska utföra kvalitetskontroll av bromshävarmarna. Examensarbetet ingår i ett pågående forskningsprojekt på Mälardalens högskola inom Lean Automation, med Robotdalen och Haldex.

Hur en övergång till ett automatiskt mjölkningssystem påverkar juverhälsan :

Automatic milking systems (AMS) have been in commercial use since 1992 and have since 1998 increased a lot. The objective of this study has been to examine the development of udder health on farms converting to AMS. The study also included a comparison of how udder health developed depending on how farms handled cows with mastitis. This was because farms choose to either milk cows with mastitis in a separate barn or in the milking robot. Other studies on udder health on commercial farms have shown that somatic cell count increases both among individual cows and in the bulk milk when converting to an AMS. No differences between before and after converting to AMS in the proportion of cows treated for mastitis can be found in the literature.

Poly - bejakandet av samtidigt begär och samtidig kärlek. : En genusvetenskaplig intervjustudie om att (vilja) ha flera kärleksfulla intima relationer samtidigt.

Poly, to live in several loving and intimate relationships at the same time, is one alternative to the mono norm. In Sweden polygamy is illegal yet in recent years poly has slowly started to enter the hetero normative political agenda and raise debate in the media. But what does poly mean, and how do those who identify with this type of relationship describe it in contrast to mono? The theoretical framework is based on a structural viewpoint of the changes in the organisation of the family and the growing de-traditionalism of society. Amongst other I use a Foucauldian perspective to explain the structural shift (yet not replacement) between an Alliance pattern and a Sexuality pattern.

Den förvandlade kommunen : Ekonomisk och social tillväxt i Örnsköldsvik 1997-2007

The transformed municipality ? Economic and social growth in Örnsköldsvik 1997-2007Author: Kristina HanssonThis thesis focuses on the economic and social growth in the municipality of Örnsköldsvik. It is a single case study and the municipality is studied through economic theories concerning regional growth in the period of 1997-2007. The aim is to analyse whether these theories, such as Åke E. Anderssons and Ulf Strömquists K-society, and other more or less microeconomic assumptions, also are applicable in smaller local contexts.

Use of oxytocin to improve diagnosis of subclinical mastitis caused by Staphylococcus aureus

Mastitis, inflammation in the udder tissue, caused by S. aureus is a big problem in dairy cattle production. It causes suffering for the cow and curing or replacing the infected cow is costly for the farmer. It is known that beef cattle also suffer from mastitis caused by S. aureus.

Fastighetsaktier och inflation : Kortsiktiga och långsiktiga samband

The purpose of this paper was to examine the inflation hedging capabilities of property shares. A common notion is that property is a good hedge against inflation. Indeed, positive correlations have been found for direct investments and inflation. However, property shares are generally perceived as a perverse inflation hedge. This discrepancy has often been quoted as evidence of property shares divergence from the development of the underlying property market.

Medveten modellering : En kompatibilitetskontroll mellan Tekla Structures 15.0 samt Autodesk Robot Structural Analysis Professional 2010

Till grund för detta examensarbete ligger en ineffektiv process, samt dubbelarbete som idag utgör arbetsgången vid CAD-projektering för konstruktörer hos Structor i Karlstad. Målet med examensarbetet är att genomföra en kompatibilitetskontroll av 3D-modelleringsprogrammet Tekla Structures 15.0 mot analys- och beräkningsprogrammen Autodesk Robot Structural Analysis Professional 2010 samt Strusoft FEM-Design. Syftet är att med hjälp av kompatiblitetskontrollen utgöra vilket av programmen Autodesk Robot och FEM-Design som bäst lämpar sig att köras tillsammans med Tekla Structures utifrån valda faktorer. Två äldre examensarbeten används för att få en uppfattning om FEM-Design. För att undvika det omfattande och tidskrävande arbetet med att skapa två modeller, en grafisk samt en analytisk modell, finns en lösning. Genom att skapa den grafiska modellen i Tekla Structures 15.0, vilket sedermera genererar den analytiska modellen, och sedan exportera den via länk till Autodesk Robot Structural Analysis 2010 behövs bara en modellering.

Prevalence of subclinical mastitis and udder pathogens in small holder dairy farms in Mapepe, Batoka and Choma areas in Zambia

Subclinical mastitis (SCM) is a well-known problem in the dairy sector, where it causes severe economic losses mainly due to reduced milk production. This is a problem not only in the western world but also in developing countries. Surveys from different developing countries have shown a SCM prevalence of 52.4 ? 88.6 % at cow level and 26.7 ? 63.2 % at quarter-level. To combat mastitis is important to optimize the milk production of the cow.
