Offentlig upphandling av ekologiskt producerade livsmedel : Ludvika kommuns, Borlänge kommuns respektive Smedjebacken kommuns erfarenheter av gruppcertifiering enligt KRAV

The Swedish public procurement correspond to approximately 400 milliard Swedish crowns every year which corresponds to about a fourth of the Swedish Gross National Product. Setting proper demands in the procurement is a useful tool to drive the development towards more environmentally adapted products and provisions. The Act on Public Procurement (Lagen om offentlig upphandling, 1992:1528) gives the municipalities opportunities to consider environmental properties during the procurement. This combined literature and empirical study investigates the experiences made by the three municipalities Ludvika, Borlänge and Smedjebacken during the process of certifying their school kitchens as organic in cooperation with KRAV. The main conclusion is that without compassion and curiosity for developing a green public procurement changes can be hard to implement.

New Generation Surface treatment for tools : A preliminary study

The surface finishing technique called black oxidation is currently being used on thetool holders made of low alloyed tool steel produced by Sandvik Coromant. Blackoxidation isn?t considered a sufficient technique because it doesn?t make the toolholders look like the quality products that they actually are. The reasoning behind thisis that the tool holders can show signs of corrosion after prolonged storing times orin countries with high humidity and temperature. The corrosion doesn?t decrease thetool holders performance, but the customers might believe otherwise.

Sociala hänsyn vid offentlig upphandling : En jämförelse mellan det klassiska direktivet och det reviderade klassiska direktivet

The first aim of this study is to examine what the differences are between the Classic directive (directive 2004/18/EC of the European Parliament and of the Council of 31 March 2004 on the coordination of procedures for the award of public works contracts, public supply contracts and public service contracts) and the Revised Classic directive (directive 2014/24/EU of the European Parliament and of the council of 26 February 2014 on public procurement and repealing Directive 2004/18/EC) when it comes to social considerations in public procurement. The second aim is to examine if the revision of the directive has solved the prior existing problems regarding social considerations in public procurement. In this paper a traditional European legal method is used. The examinations show a number of things, including the Revised Classic directive involving codification of case law, references to other sources of law and some clarified rules as well as new provisions. The regulations regarding reserved contracts, technical specifications, and selection criterion are satisfied in the Revised Classic directive.

Kampen för ökad tillgänglighet : - om enskilda aktörer, policynätverk och förhandlingsarenor i utarbetandet av EU:s bussdirektiv

The Motor Group of the European Council was commissioned in the autumn of 1997 to prepare a proposal for a new European Bus and Coach Directive. In the beginning, most of the Member States did not have the accessibility requirements as their main concern; still a smaller network with actors from the National delegations from Britain, Germany and Sweden would influence the other National delegations in the Council group to finally agree to retain the requirement of accessibility of the Directive. Within the EU decision process, the European Disability movement acted as a strong player during the whole negotiation process using the proposal to a new Bus and Coach Directive as a tool to influence key actors to go towards a Directive with a strong approach for accessibility.Policy Transfer and Policy Transfer Network are used as analytical tools to understand and structure the transfer of the question of accessibility during the negotiation process. Actors understanding how the bureaucratic process works within the EU decision system have a chance to contributing for the changes in the directions they wishes for within a range of policy areas. The principal aim of the Directive was to guarantee the safety of passengers and to provide technical prescription in particular to wheelchair users.

This report deals with handling and interim storage of soils which are planned tobe reused in construction works. The types of soils that are dealt with are gravel, topsoil and sand. The thesis work has been carried out in collaboration with Skanska Sverige Väg och Anläggning Sydost. The main goal is to find an area for using to store soil in between projects.Studies of laws and regulations regarding exploitation and storage of soil has led to a theoretical background upon which the report is based. Background informationhas also been gathered in meetings with the employees at Tekniska Kontoret and Länsstyrelsen in Jönköping.On the basis of literature studies results, a general template has been developed for which desirable properties a possible location should meet.The model was applied to find a number of possible options in the vicinity of Jönköping.

Samband mellan tjockleken hos PVD-skikt och förslitningsbeteendet vid svarvning

This project has as main goal to study the influence of the coating thickness, deposited by arc-PVD- technology, on the wear resistance of coated cemented carbide inserts in three different turning operations. An additional effort has also been made to develop a new test method for evaluating flank wear resistance. Three different coating types (Coating A, Coating B and Coating C) have been studied in three distinctive thicknesses (2, 4 and 6 µm) for each type. For two of the coating types (Coating A and B) special studies has been done with the thickest coating, creating two additional coating versions of the thickest coating, by changing various deposition parameters, with the aim to enhance the cohesive properties of the coating and lower the residual stresses at the cutting edge. The results show increased crater wear resistance with increased coating thickness for all coating types, but the amount of increase changes with coating type (Coating A>B>C).

Utredning av primärluftförvärmning till två avfallseldade pannor

The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.

Funktionsupphandling av solelanläggningar

This thesis aims to contribute to improved functional procurement of photovoltaic systems, PV systems. Functional procurement means that criteria concerning a function are set rather than specifying technical details or products. Possible advantages and difficulties in using functional procurement have been analyzed by interviews, simulations and a case study. Electricity production and surplus production for different scenarios have been simulated via MATLAB. The MATLAB script was also used to generate rules of thumb on feasible solar fraction for six different load profiles; a church, a farm, a car mechanic, an office, an industry and an apartment building.

Se upp för dörrarna, dörrarna stängs. : Invandrare med akademiska utbildningar

Uppsatsen belyser invandrade akademikers erfarenheter av Söderhamns kommuns Insteg till Svenskt Arbetsliv, en kurs för att underlätta inträdet på svensk arbetsmarknad samt invandrade akademikers syn på hur de kan få jobb i Sverige. Det är svårt för invandrade akademiker att få arbete som motsvarar deras utbildning.  Metoden för undersökningen har varit semistrukturerade intervjuer med fyra invandrade akademiker. Resultatet visade att ISA-kursen gav information om hur man söker jobb i Sverige och hur den svenska arbetsmarknaden fungerar, kontakt med arbetsgivare samt träning i att prata svenska. Resultatet visade att det behövs kurser i svenskt fackspråk och ekonomiskt stöd för att studera svenska på hög nivå. Resultatet överensstämmer med Svenskt Näringslivs åsikt att brist på effektiva utbildningar i svenska gör att Sverige inte kan förvalta hitflyttad välutbildad arbetskraft.
