Konstruktion av 6:e axel på 5-axligportalfräsmaskin

During springterm 2010 Erik Persson and Magnus Hansson performed their ThesisWork with DIAB Laholm, in Hallands County for University of Halmstad.The project has been a product development project without exterior customers. Thusit had a great emphasis on functionality and less emphasis on marketing and such.This reflects the ambition to develop machinery to be used within the productionfacilities of DIAB Laholm, not to be sold to exterior customers.Main objective has been to create machinery which enables the production ofrotational symmetric work pieces within a NC-milling machine with 5 axles. Thework pieces milled will be made of DIAB?s material Divyncell with varyingdensities.The project has followed Fredy Olssons method involving Principal ? Primary ?Manufacturing constructions. However a complete manufacturing construction hasnot been made since DIAB just wanted a good Primary construction which will serveas a base for finishing touches at DIAB.By the end of the project material including calculations has been sent to DIAB andthey will finish the work and manufacture the machine if they find economic viabilityin this.The work method has been suited for this by several reasons, it was created withthese projects in mind and it?s also the method most familiar to us..

Kartläggning av snökanoner över Östersjön

Convective snowbands is a weather phenomenon that is associated with heavy snowfall in a limited area. They are formed over ice-free parts of e.g. the Baltic Sea when there is a cold easterly airflow over relatively warm water. These convective snowbands can cause large amounts of snow along the Swedish east coast, often causing traffic hazards. Sometimes they can even paralyze an entire community.  In this study, convective snowbands that have formed over the Baltic Sea during the period 1980-2009 are examined, in order to find out how often they occur, what place they are most common and in what month they usually appear.

Erosionsskydd i strandzoner :

Erosion in coastal areas is a common problem all around the world. The range of the problem depends on several factors, i.e. type of bed-rock and soil, wind and wave climate. Another factor is whether the area is of high interest, i.e. if the area is important for tourism and recreation, if there are houses and other buildings close to the shoreline or if it is a site of special scientific interest.

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.

Skattereformen 1910 : när ett skatteexperiment permanentades

On 1 January 2007 abolished Sweden as one of the last countries in EU the wealth tax. This wealth tax was in Sweden for almost 100 years. As the great debate in the context of tax reform in 1910 was not so much about the introduction of a wealth tax. The discussion was instead on the wealth tax would be proportional or progressive together with the income tax.When the government with and there finance minister, Carl Swartz, presented its government bill, 1910:88, 11 March 1910, the draft regulation on income and wealth tax was said, that now they had finally made a shift in the direct tax to the state. A change had been sought and it would have been great difficulties to be overcome and it would have been deeply entrenched ideas about this tax reform impossible.Despite all the protests from the wealthy in society, so continue this conservative government through reform with the strong support of many conservative politicians who had most to lose from this tax reform.

Utveckling av 300 kg HD Lightlift för belysning och liknande laster

The company LightLift Esystems AB manufactures patented motorized lift systems for the illumination of halls with high ceilings. The company wants a new design for singular heavy lights in order to be more competitive.This project consists of the development of the new design under the requirements and specifications imposed by the company. The new design must support lights up to 300kg and keep the overall dimensions as low as possible without modifying the driving unit.This document contains all the designing steps followed to reach the final solution as well as the material selection, manufacturing process and assembly of all the parts that form it.The solution obtained shows to be very competitive with other alternative products, since this new design triples their maximum load capacity while the dimensions are very similar.In this context, the optical appearance was also very important to the company and so it was another main objective of this project. From an aesthetical point of view, the final solution proves to be very compact and versatile since it can either be hidden behind a false ceiling or covered by a plastic case that gives the design a very nice look.Finally, the solution achieved fulfils all the requirements and specification previously imposed. It is reliable, compact, cheap to manufacture, easy to assembly and it has a good optical appearance. .

Den dubbla avvikaren : En kvalitativ studie om frivårdsinspektörers konstruktioner av kvinnor som begår brott

The purpose of this study has been to examine how female probation officers construct the concept of women who commit crime. This have been done by examining how the probation officers describe the phenomenon from their own point of view, how they perceive society's view of the phenomenon, how they describe the women's self-images and how their own perceptions affect the treatment of these women. To fulfill this aim the study is based on qualitative interviews with five female probation officers. We analyzed their statements by using Gender theory, Goffmans stigma term and Beckers deviant term. The result of this study shows that women who commit crime are described more as victims than offenders and that they are constructed as deviant in two ways; both in relation to the law but also in relation to their gender.

Konduktivitet i vattendrag som indikator på sura sulfatjordar

Increasing attention is being given to acid sulphate soils wherever they occur. The problems that leaching sulphate soils gives with significant lowerings of pH and mobilization of heavy metals influence large spectra of our society from fisheries to agriculture to construction. Mapping these soils is consequently of great importance and the methods of doing this is very much lacking in function and precision. This study was therefore carried out to investigate whether conductivity in running water can be used as a simple instrument to identify acid sulphate soils in the catchment. 31 coastal streams in the county of Västerbotten were analyzed for different catchment properties such as occurence of marine sediments and basic water chemistry including conductivity and sulphate.

Förstudie för SWIFT Boeing 737 : Kabinlayout med räddningsutrustning

Sammanfattning Detta examensarbete är tänkt att fungera som en förstudie med syftet att komma med tänkbara lösningar på hur räddningsutrustning ska kunna lastas i kabinen på en Boeing 737-800. Uppdragsgivaren är Scandinavian Airlines som har fått en förfrågan av MSB hur det skulle kunna se ut. Tanken är att det ska bli ett räddningsplan som ska komma till undsättning för människor i katastrofområden. MSB har begärt att två versioner ska finnas. En heavy- och en medium-version, där skillnaden är antalet människor och mängden utrustning som medföljer.

Skolsituationen för elever med betyget MVG i matematik : En fallstudie av fyra elever i grundskolans årskurs 9

This thesis has been focused around the Diels Alder reaction with the goal to design an enzyme catalyzed reaction pathway. To achieve this goal computer aided enzyme design was utilized. Common traditional methods of computational chemistry (B3LYP, MP2) do not do well when calculating reaction barriers or even reaction energies for the Diels Alder reaction. New calcu- lation methods were developed and tested. This was the focus of the first part of the thesis, by choosing a small system, extensive and heavy calculations could be done with CBS-QB3.

"Vi har våldet i blodet" - En kritisk diskursanalys av Landskrona Posten 2006

On the 11th of march 2006, the journal Landskrona Posten began an article series with the ambition to review the juvenile gangs in the city of Landskrona. The articles received heavy response from the readers. About six months later Landskrona was the centre of attention in the Swedish media. 22,3 percent of the city's population had voted for the nationalist party ?Sverigedemokraterna? in the municipal election.

Uppkomst av materialspill vid nyproduktion av flerbostadshus

Construction waste from the housing industry includes all unnecessary consumption of building materials. The definition of construction waste is construction materials that has not been built in and becomes waste. Constructions waste can be divided into two types of contributions: operational and work site contribution. Some of the common construction materials in housing industry have such low usage level as 75 % and the rest becomes construction waste. Low usage of construction materials creates unnecessary costs and has a major environmental impact.

Ekologiskt uppfödda kycklingar : en jämförelse mellan två olika foder

Organic rearing of broilers is not a large production in Sweden. In order to create a sustainable yet efficient production of organically produced poultry meat, at a price that the consumers are willing to pay, much more knowledge is needed. It is therefore important to do more research on organic broilers under Swedish conditions. This report is aimed to be a base for further studies. In the study 2000 broilers of the hybrid Ross 308 divided in to two equal groups. The broiler hybrids that are used in Sweden are selected for a high growth rate and are normally slaughtered at the age of 5 to 6 weeks, with a slaughter weight of 1.7-2 kg.

Arbetsmiljö och säkerhet : På mindre företag inom byggindustrin

The accident frequency in the construction industry has shown a downward trend every year but this trend was broken 2010th. It is often lack of precautionary measures within work environment and safety that is the cause of accidents. The big construction companies understand the importance of precautionary measures within work environment and safety, as they spend a lot of money and time on that matter. By examining the work environment and the safety of the small construction companies you can see how they work. The report will presents how these small companies work with work environment and safety, and also how they follow the safety instructions that are available and how they make use of safety equipment.

Jämställdhet, barnarbete eller miljöarbete

ABSTRACTIn this study, five people were interviewed who are involved in a drug-assisted program for opiate addiction, also called substitution program. The meaning of substitution is that these clients' drug addiction is replaced with substitute preparations, either methadone or Subutex in an orderly manner. The clients of the researcher decided to study the substitution program have all been a heavy opiate addiction for years. Their participation in the replacement program is more than two years, and those who have been around the longest have been in the program for six years, so long as the substitution program has existed in Visby.This is a qualitative study in which interviews are conducted face to face with each individual client, and the interview was unstructured in the sense that no specific issues made in advance. The interviews have been themed, and the researcher has gone through various areas of life around the respondent.
