Eftermarknadens möjligheter : En studie av Swecon AB:s tjänsteutbud

ProblemThe manufacturing industry is a mature industry where the profit margins are small and the competition is hard. This makes it hard for both manufacturers and resellers to gain market shares and reach reasonable profit margins only by selling products. Therefore Swecon who is reseller for Volvo Construction Equipment tries to find alternative methods and ways to increase their profit. An alternative source of income could be to develop the range of services that are connected to the ground products.PurposeThe purpose of the thesis is to examine how Swecon in southern Sweden can improve their offers of existing services connected to the ground product and investigate the demand of new such services.MethodThis study is based on a qualitative study of five of Swecons local offices and five of Swecons customers. The empirical framework is mostly based on personal interviews but in some cases information was retrieved by using phone interviews.

Hur påverkar olika ståndortsfaktorer överlevnaden hos planterade regnskogsträd i en sekundär regnskog på Borneo?

De tropiska regnskogarna är några av de mest komplexa och artrikaste ekosystemen i Världen. Stora delar av de naturliga Dipterocarpa regnskogarna har under de senaste decennierna försvunnit helt p.g.a. ändrad markanvändning (oftast jordbruk), eller degraderats till sekundära regnskogar p.g.a. torka, bränder och selektiva avverkningar. Det finns därför behov av rehabilitering för att få tillbaka artrikedomen i skogarna. Syftet med det här kandidatarbetet är att titta på hur överlevnaden hos plantor i ett rehabiliteringsprojekt i en sekundär regnskog påverkas av olika ståndortsfaktorer.

Konstruktion av truckmonterad hjulhanterare

GBD-Storage Systems is a company that provides the industries with products for efficient storage.The company produces pallet racks and accessories like cassettes and extending units. The companyhas also supplied tire racks for a number of tire companies. The company's CEO Gunnar Berglund hasfor some time had an idea to improve the working situation of the workers on tire firms by allowingthe wheels to be handled by a counterbalance truck. The current situation poses numerous heavy liftswhen the tires are handled and therefore is hurting the workers.This thesis has been aiming at helping the GBD-Storage Systems by developing a concept of howan accessory to counterbalanced trucks can be designed to cope with the wheels. This concept willthen be produced as prototype by the company.

When I die, I want to be recycled - a study of the view of the funeral industry on the handling of metals in cremation

Kremering är idag det vanligaste jordfästningssättet i Sverige, de allra flesta som avlider kremeras och gravsätts i urna. Frågan om hur de metaller som finns i kroppen men inte får plats i urnan hanteras har hittills inte väckt så stor uppmärksamhet, speciellt inte ur miljösynpunkt. Dock handlar det om åtskilliga ton metall som varje år grävs ner på kyrkogårdar runt om i landet. Denna metall påverkar dels miljön negativt, dels kommer det att ta upp mer och mer plats på kyrkogårdarna i framtiden, och att gräva ner metaller imarken är inte ett miljöoptimerat sätt att hantera dessa. Det finns dock andra saker än bara miljön att ta hänsyn till i denna fråga.

Lyfta Lätt Tekniskt hjälpmedel för pakethantering

People working with handling parcels in terminals are often victims of musculoskeletal injuries. This is largely due to the hazardous lifting of too many parcels which are too heavy and unsuitable work postures. The human body?s ability to lift and grasp objects is so outstanding that developing a device with the same capability is very difficult.The goal of the project has been to develop a technical device that will improve the handling of parcels with regard to ergonomics. The area of concern was the lifting of parcels between the conveyor belt and the cargo space of the freight car.

The secret life of Bacillus anthracis

Bacillus anthracis is the causative agent of anthrax, a serious and globally distributed zoonosis affecting a wide range of wild and domestic animals, invariably also humans. However, although known to humans since biblical times, much remains to be elucidated concerning the ecology and transmission of this bacterium. Of particular interest is the Bacillus anthracis spore, the uptake of which is the predominant way to contract anthrax and which is legendary for its resilience in the environment and thus crucial for persistence and spread of the disease. Hence, the aim of this study is to review the natural transmission of Bacillus anthracis and investigate potential means by which soil persisting Bacillus anthracis spores reach concentrations sufficient to infect susceptible hosts. When reviewing the literature, three different theories can be distinguished. Firstly, ?the incubator area? hypothesis suggests that favourable soil factors, possibly in association with amoebas, may constitute an environment supporting repeated spore-bacterium-spore cycling, thus increasing the local amount of spores.

Konceptstudie av kombinerad nödgenerator-trädgårdsredskap : Concept Study of a Combined Emergency Generator-Garden tool

The present study concerns a concept development of a product idea that Bengt Magnuson, associate professor, had when a heavy storm caused a widespread power failure of long duration. With a basic power-producing unit one should be able to get through a power loss. The product could also be useful for other tasks if different modules are connected, e g grass mower or snow-blower.According to the product idea the basic unit will be able to produce electric power enough for a fridge, freezer, TV, and a few electric lamps. Normally the basic unit can be used e g as a mower, when such a module is attached. An increased number of tasks would make the contraption useful and tempting for those who do not own an electrical power set in reserve.

A serological study of Rift Valley Fever virus in two regions in Tanzania

Rift Valley Fever (RVF) is a disease caused by Rift Valley Fever virus (RVFV), which is an arbovirus. An arbovirus is a virus that is transmitted by an arthropod vector, in this case a mosquito. The virus is a member of the Phlebovirus genus in the family Bunyaviridae. It was first identified in the Rift Valley in Kenya in 1930. The disease is a zoonosis but mainly affects domestic ruminants inducing massive abortions and a high mortality among young animals.

Effects of Driver, Vehicle, and Environment Characteristics on Collision Warning System Design

The purpose of the present study was to examine effects of driver, vehicle, and environment characteristics on Collision Warning System (CWS) design. One hypothesis was made that the capability of collision avoidance would not be same among a driver, vehicle, and environment group with different characteristics. Accident analysis and quantitative analysis was used to examine this hypothesis in terms of ?risk? and ?safety margin? respectively. Rear-end collision had a stronger focus in the present study.

FaR för en heterogen målgrupp med komplexa behov : Förskrivares upplevelse av fysisk aktivitet på recept (FaR) och samverkan med aktivitetsmottagare

  Aim. The aim of the study was to describe how nurses in home care experience to pursue palliative care in ordinary housing. Methods. The study had a descriptive design with qualitative approach and was carried out through semi-structured interviews with 14 nurses in home health care from two medium-sized Swedish municipalities. The material was analyzed with manifest and latent content analysis. Findings. The underlying theme that emerged in the study was: Working with palliative care in the patient´s own homes is positive but challenging. Informants describe among other things that they perceived palliative home care as meaningful and that relatives have a central role in the palliative home care since they are close to the patient around the clock. The stress that emerges from the heavy work load and the long geographic distances are described as strenuous and to affect the care in a negative way. Informants describe the home environment as challenging as it is often not adapted for care and the collaboration with the palliative team is described to be experienced as both positive and negative.

En studie av Föreningen Värmlands Arbetarkvinnors Semesterhem för husmödrar; exemplet Frykenstrands semesterhem 1943-1974 : Hur omsattes statens visioner i praktiken?

Sweden had in the early 1930's the lowest birth rate in the world. Population Commission which was established in 1935 concluded that one of the biggest social problems was the working women?s heavy workload. To deal with the low birth rate reforms and programs were founded both in order to help the women but also in order to support the inadequate motherhood. Government grants were set up to start the so-called vacation home for housewives where the government?s visions of the vacation homes were active rest and recreation.     Based on the Leisure Inquiry report regarding vacation homes for housewives - the purpose of this paper is to examine how the government visions regarding vacation homes for housewives were practiced and how the future of prevailing gender contract affected the holiday home.

Att systematiskt hantera kunskap vid planering av ny infrastruktur : En fallstudie om skyfallsskador på riksväg 90 i Kramfors kommun

Natural disasters are becoming more common due to climate change and it is important to adapt the society and its infrastructure to withstand events such as extreme rainfall. Precipitation is an important climatic factor affecting the transport and annually generates the cost of millions in damages, over the past 40 years heavy rain has increased and will continue to increase in the future. The extreme rainfall that occurred in Kramfors municipality in September 2013 led to flooding and destroyed several roads, including highway 90, which recently both had been rebuilt and given a new stretch of road. Extreme rainfall had also occurred in the municipality earlier.  The aim of the thesis was to examine how the Swedish Transport Administration handles new knowledge gained after natural disasters and how this is used in the planning of new roads.

Charlie don't surf! : En studie av det postkoloniala perspektivet i amerikanska Vietnamkrigsfilmer

Syftet med denna studie är att i sex amerikanska filmer som tar upp kriget i Vietnam undersöka hur den västerländska och den orientaliska kulturen skildras i relation till varandra utifrån ett postkolonialt perspektiv. Både framställningen av såväl amerikanerna, fienden och sydvietnameserna har studerats ur detta perspektiv. Detta undersöks genom att koppla till teorier och begrepp såsom semiotik och ideologi och metoder såsom diskurs och diskursanalys, mise-en-scéne och filmanalys. Studien undersöker om det skett någon förändring av det postkoloniala perspektivet i filmernas framställning. Undersökningen inkluderar: Gröna Baskrarna, The Deer Hunter, Apocalypse Now Redux, Plutonen, Full Metal Jacket och We Were Soldiers.
