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.
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.
Diesel Dubbelbränsle Teknologi
The work covered in this report includes a literature study of the diesel dual fuel technology(hereinafter referred to as DDF). The literature study covers earlier work that has been doneregarding the use of compressed natural gas (CNG) and diesel in a DDF system. Moreover a onecylinder research diesel engine was fitted with a CNG fuel system for experimental testing. Theinstallation of the engine and the test cell is described. Results from the tests are presentedcovering emissions, heat release and pressure traces from the DDF-concept.During the literature study it was found that most research was related to heavy duty dieselengines.
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.

Ha lite jävla stake! : En kvalitativ innehållsanalys av hur manlighet respektivekvinnlighet framställs i Filip och Fredriks podcast
The purpose of this study is, based on theories of gender and hegemonic masculinity, to studyhow masculinity and femininity is constructed and reproduced in one of the most popularSwedish podcast: Filip & Fredriks podcast. The main theory in this study is that gender issocially created and sustained by humans through language and interaction with others.The study's research questions is: How are gender roles/gender portrayed in Filip & Fredrik'spodcast? What characteristics are attributed to men and women in Filip & Fredrik's podcast?How does Filip & Fredrik's podcast represents conditions and power relations between menand women?Through an linguistic textual analysis, which is an application of discourse analysis, I seek toget beneath the surface meanings of texts and examine more implicit social meanings andideologies regarding gender. It includes an analysis of metaphors, word choices and syntax.The analysis shows underlying values and ideologies that indicates gender structures in abroader societal context. Choice of words and metaphores in Filip & Fredriks's podcastexpresses symbolism where men and male-typical attributes are highly valued, whilst womanand female-typical attributes is being devalued and representative of the opposite.Masculinities and femininities are also constructed and represented in various ways throughsentence constructions that guides the listeners in certain directions.
Tilläggsisolering - lönsamt enligt en livscykelkostnadsmodell?
It is found that the properties of the record years of 1965-1975 is leaking a lot of energy andthese properties are facing a major energy efficiency. From the energy aspect, the facade isafflicted with poor thermal insulation which is a big problem. To address this problem addinginsulation is a good alternative to reduce overall energy consumption of a building. Thewindows on these buildings are also a problem from the energy point of view. Therefore,there are many reasons considered for energy upgrading.
En idrottsklubbs varumärkesidentitet & varumärkesimage
This essay deals with the rationale and aims for doing cultural or aesthetic activities and projects in schools, and gives special focus to a specific group of students, attending schools provided at special residential homes for young people (sa?rskilda ungdomshem). These homes receive young people with psychosocial and substance misuse problems and who show tendencies towards criminal behavior. The essay investigates how working with a cultural project in schools at these residential homes is justified and also elucidates how this specific group of students and their problems are constructed in the documents surrounding the project. The essay will further ponder over possible educational and pedagogical consequences of these constructions.The investigation has its theoretical frame work in curriculum theory.
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.
