Coordinator of public health has recently become a new profession in the field of Health Promotion. During the last few years the pedagogic perspective has been increasingly important for the coordinators as a way of adapting their work methods to the circumstances. The conditions for coordinators of public health differ between municipalities and thus their tasks and responsibilities may vary with the local structure. According to the literature there are several ways to conduct Health Promotion and it is in the hands of the coordinator to adjust the methods to fit local conditions. The purpose of the study was to examine what influences the coordinators of public health and how that affects their work methods.

Syftet med detta arbete var att ta fram en arbetsmetod som underlättar arbetsgången med verktygsoptimering på Scanias produktionsenhet för motorkomponenter. Metoden ska beskriva hur arbetet ska ske internt såväl som hur arbetet ska ske med verktygsleverantörer. Arbetsmetoden ska både behandla hur optimering av befintliga bearbetningsprocesser ska gå till samt hur tillvägagångssättet för verktygsoptimering vid anskaffning av nya verkstadsmaskiner.Som metod valdes att studera befintliga arbetsprocesser på Scania samt att utföra semistrukturerade intervjuer med personer i funktioner inom motor som idag arbetar med dessa frågor. Dessa funktioner har främst varit bearbetningstekniker, beredare, metodlabb, inköp, produktionstekniker, produktionsledare och operatörer.Intervjuer genomfördes också med representanter för de tre mest anlitade verktygsleverantörerna.Resultatet blev att en befintlig tidigare okänd väl fungerande arbetsprocess har identifierats. Processen lider idag av vissa svårigheter vid dels initieringen av nya uppdrag samt vid införandet av framtagna lösningar.

StoraEnso decided in year 2002 to build a pulp mill in the province of Guangxi, southernChina, and also establish eucalyptus plantations to provide it with raw material. By 2010StoraEnso controls about 90 000 of planned 120 000 ha, out of 75 000 ha is already plantedwith Eucalyptus.By using better genetic material, improve the tending, selecting the sites more careful and byusing a proper fertilization regime StoraEnso hopes to increase the mean annual incrementfrom today?s 25 m3/ha, on bark, to 35 m3/ha. This study is one part in this work to increase themean annual increment in the plantation.This master thesis is the forth in a series, that has followed up a fertilization trial that startedin spring 2006 when the trial was laid out and treatments decided. The aim with the trial is toexamine the production potential of Eucalyptus urophylla in Guangxi, southern China.

The idea for this project was initiated together with one of the leaders in the forest, paper and packaging industry. To get through an A/R CDM process the company is exposed to the risk of failing the process or that the overall costs will exceed the benefits of the project. This would delete the incentives to invest in GHG removals compared to purchasing emission allowances on the carbon market. The questions that have been raised and needs clarification in the thesis are the following:? From a company perspective, what are the incentives for implementing Forest Clean Development Mechanism (CDM) projects?? What is a likely financial outcome of a reforestation CDM project on degraded land in the Guangxi province of the Peoples Republic of China?? When does an investment like this break even with the cost of buying market based carbon emission allowances? The objective of this master thesis is to carry out a research about the incentives for forest, paper and packaging companies to invest in reforestation through the clean development mechanism.

In today?s fast growing and closely connected society, a reliable and energy efficient transportation system is more than ever desirable. Nowadays the significant part of the transportation sector?s energy demand is supplied by fossil fuels.Improving energy efficiency in combustion engines will result in reduction of fuel consumption and CO2 emissions. A modern internal combustion engine has an efficiency of 30-45 %, where the most energy loss occurs as result of heat losses in the exhaust and cooling systems.

De förklarande variablerna har valts med hänsyn tagen till fakta presenterad i bolagens årsrapporter samt ekonomisk relevans.

Listeriosis, which is caused by Listeria monocytogenes, is a rare food borne disease that primarily affects people whose immune system is weakened. These may be elderly people, pregnant women, new-born infants and individuals on immunosuppressive medication. The most common symptoms are meningitis, septikemia and abortion. The mortality is high, on average 20-30 %. In recent years the number of cases in Sweden has increased.

When drivers overnight in the truck lots of electric energy is consumed by heaters, fans, lights and other extra equipment. If the engine is not running, this energy is taken from the lead/acid batteries of the truck which then needs to be recharged during operating hours. The fact that the charge acceptance of the lead/acid batteries is dependent on the temperature makes it hard to fully recharge the batteries at lower temperatures. A negative charge balance can lead to starting problems within a few days use in cold climate.In this thesis work, the effects of different battery charging concept are evaluated on the most common Scania battery (175Ah). A battery model is implemented in Matlab and some simulations of charging are made.

Scania är en av världens ledande tillverkare av lastbilar och bussar för tunga transporter samt industri- och marinmotorer. Efter lansering av den nya lastbilsserien under 2004 som utnämndes till ?Truck of the year 2005? så tittar hyttutvecklingsgruppen framåt på nya projekt. Ett område inom hyttinredning som man vill fördjupa sig i är dörrpanelen. Med dörrpanel menas den del av inredningen som sitter på dörrens insida och normalt sett innehåller öppnings- och stängningshandtag, fönstervevar/elhissar, förvaringsfack etc.

The aim of this study has been to describe the ongoing region enlargement process in the region Mälardalen, located in the east part of Sweden, and to investigate how this process can affect the local level. The study is especially orientated on public communications and accessibility. The intention has also been to examine how the local accessibility can affect the re-gional development in Mälardalen. The local investigation object that has been chosen for this research is the city Strängnäs, situated in the province of Södermanland. The city of Strängnäs and the cities in it?s near geographic surroundings has been the benchmark for this casestudy, in which the local accessibility with public transportation has been investigated.

Former studies have shown that a considerable part of industries? energy usage can stem from idle times in the production. This thesis, carried out at Siemens Industry sector, evaluates the potential for using the control system to automatically put machines into energy saving mode during idle times. The main part of the thesis consists of a case study performed on machine tools at a Scania production site in Södertälje. Through load measurements the potential for energy savings was determined.The results show that there is a great potential for energy savings during idle times at the site.

SammanfattningI dagens miljöfokuserade samhälle ställs det allt högre krav på den tunga fordonsindustrin varvid den gällande miljölagstiftningen skärpts i flera steg de senaste åren. Scania tillverkar tyngre fordon och motorer som alla måste följa de kommande utsläppskraven. Detta innebär att motorernas utsläpp måste reduceras varför avancerade efterbehandlingssystem har införts i ljuddämparen. En metod för att rena avgaserna från kväveoxider är SCR-teknologi (Selective Catalytic Reduction). Denna teknik bygger på att en urealösning sprutas in i avgasflödet.

Detta examensarbete utfördes som ett tvärfunktionellt projekt mellan Scanias motorutveckling och motormontering i Södertälje under sommaren och hösten 2007. Arbetet var mestadels förlagt till Scanias motormontering, by 150. Examensarbetet utgör den avslutande delen av civilingenjörsutbildningen i maskinteknik, inriktning maskinkonstruktion vid Luleå tekniska universitet. Projektet behandlar ritningskrav på täthet för gjutgods och metoder för att kontrollera tätkraven. Läckage är förutom prestanda den dominerande anledningen till att ca 10% av Scanias motorer inte godkänns efter provkörning i samband med monteringen.

This thesis work is the last part of the Master of Science education inmechanical engineering at KTH, Stockholm.The aim of this project was the development of a Multi-zone modelfor NOxformation in Diesel engines. Because of the stringent emissionlegislations, great effort is made to decrease the fuel consumption and theharmful emissions of internal combustion engines. Computer simulationsplay a decisive role in this context because they substitute the expensiveand time-consuming laboratory tests.The model is based on a multi-zone approach and uses the wellknownExtended Zeldovich Mechanism which gives a relation to calculatethe NO formation rate using the concentration of different gas speciesinvolved in the process.All the most important phenomena involved in the Diesel combustionhave been modelled. A special attention is then paid to the equilibriumconcentration calculation; this is a significant part of the model whichstrongly influences the following steps.A Simulink model has also been developed. This second version isbased on the previous model and it is made especially to allow theconnection with other external softwares, GT-power in this case.
