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. .

Kollektiv dominans - har bedömningen blivit hårdare?

Abstract One of the essential conditions of the co-operating within the EU is that homogeneous conditions of competition prevail within the entire common market. The competition policy in the EU should guarantee that the competition is not distorted in a way that would prevent or create difficulties for the free mobility of goods and services between the member countries. The policy of competition should also guarantee that no new protectionistic obstacles will be formed, regardless of if it is being done by actions taken by member countries or as a result of actions taken by companies in order to set limits to the competition. Companies putting to an abuse their dominant position on the common market, or on a substantial part of it, is irreconcilable with the idea of the common market in case it could interfere with the trading between member countries, and is thus prohibited. The purpose of this dissertation is to describe the collective dominance from the view of the commission's interpretation of the practice of article 82 in the EG - treaty.

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.

Metodutveckling för analys av klorfenoler i jord samt analys av förorenad jord från ett sågverk

In this final thesis, an existing method for analysis of chlorophenols (CP) in bottom sediments has been updated and adjusted for analysis of chlorophenols in soil. The covalent bonds between the chlorophenols and the soil matrix were broken through basic hydrolysis and the chlorophenols were then separated from the water phase through addition of sulphuric acid followed by ether extraction. The chromatography was improved through extractive acetylation of the chlorophenols.The updated method was then applied on soil samples from a contaminated area (a former sawmill in Hyttsjö, Östergötland, Sweden).The analyse was preformed by GC/MS with respect to 2-MonoCP, 4-MonoCP, 2,4-DiCP, 2,6-DiCP, 2,4,6-TriCP, 2,3,4,6-TetraCP and pentachlorophenol (PCP).Contamination of chlorophenols in nature can be explained by the former use of wood preservative chemicals based on chlorophenols. In the 1960s and the 1970s these chemicals were used in Sweden, but due to their toxicity they were banned by the Swedish government in 1978.In Hyttsjö a pentachlorophenol-based product named Santobrite was used for several years. The concentration of PCP in the soil samples from Hyttsjö varied from 0.2->1.8 ng/mg dry substance.

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.

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.

De konkurrensrättsliga sanktionsformerna

The fundamental prohibitions against anti-competitive agreements and abuse of a dominant position are set out in the EC Treaty, articles 81 and 82 respective CL 6 and 19 §. EU: s objectives can be said to promote economic and social development within the community. These objectives will be achieved, among other things, through the establishment of a common internal market. In order to achieve a common market, where companies from different nations compete on equal conditions, it is not enough to prevent the member states from distortion of competition in the market. The free competition and thereby the advantages the common market is assumed to create, can also be limited through measures taken by companies.

Brännskuggat fanér - en metodanalys

This thesis is about a part of the marquetrytechnique, scorching. Scorching is made by heating up something, put a veneer into the heated substance and make a controlled burning. This technique is old but still used today and have according to me great potential for development. In my work I wanted to give the scorching greater room then I earlier have seen. I wanted the scorching to be the dominant ingredient for a decorative element in a piece of furniture or an interior.

The study also aims to draw attention to the interventions for abused women during the legal process.The results are based on interviews with professionals in the justice system, and on observations in the courtroom. Overall our results show that abused women are in need of a great quantity of help and support before, during and after the negotiation. The legal process is very stressful for the women.

Interferences during analysis of polyphenols in fruit juices

One of the most commonly used methods for analysis of polyphenols is the Folin-Ciocalteu (FC) method, where the FC reagent has been reported to interfere with some substances in fruit juices. The interfering substance that is present in the highest amount in most fruit juices is ascorbic acid. In this study, the total phenolic content (TPC) of three fruit juices was analysed by the FC method as well as with an enzymatic method with hydrogen peroxide oxidoreductase type II (HRP) for comparison. To investigate how the interfering ascorbic acid affects the TPC, juice samples were analysed after removal and addition, respectively, of ascorbic acid. The samples were analysed with HPLC both before and after the extraction phase of the FC method.

?Innanfo?r hemmets va?ggar? : En kvalitativ studie om bista?ndshandla?ggares erfarenheter och uppfattningar kring a?ldre personer med problematiskt fo?rha?llande till alkohol

This study is qualitative and aims to describe and analyze how senior citizens with alcohol- related problems are recognized by social workers within local care for the elderly. The empirical material consists of eleven semi-structured interviews which was completed with the help of social workers within local elderly care. The findings of the study shows that the processing of the senior citizens alcohol related problem can be explained as an identified ?awareness process.? Further, the findings of the study shows that awareness is often made by others than the social workers themselves. The study has also showed that known versus unknown information about present alcohol-related problems, tends to be crucial for when and how awareness is made in the ?awareness process?. .

Demokrati och lagprövning - Om rättfärdigandet av en positiv respektive negativ inställning till lagprövning som institution i demokratin

This essay concerns the issue of democracy and judicial review. The main focus is on the justification of both a positive and a negative attitude towards judicial review, and the values these justifications are based on. The analysis is made by textual analysis of four authors with different opinions of the subject matter: Robert Dahl and Jeremy Waldron who has a negative attitude towards judicial review, and Erwin Chemerinsky and Ronald Dworkin who are positive about it. In the analysis an analytic frame is used which consists of different dimensions and aspects of the problem of democracy and judicial review. The study shows that there are important differences in democratic values between a positive and a negative justification of judicial review.

Att utkräva ansvar - en analys av Vattenfalls verksamhet i Tyskland

With the expansion onto the international market almost a decade ago, Swedish energy corporation Vattenfall began it's breaking and burning of coal on German soil. Criticism aimed at Vattenfall peaked in the mid 2000s with the revelation of large quantities of carbon dioxide emissions and the re-location of villages and graveyards in German states Brandenburg and Saxony. The purpose of this thesis is to show where the responsibility for these activities lie. By analyzing the history of, and the political debate surrounding, Vattenfall, I will show that the prevailing policies of right- as well as left-wing parties in the 20th century were all, regarding this matter, market oriented. I will also show that these market promoting policies made possible a situation where the transparancy of, and state control over, Vattenfall were close to eliminated.
