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.

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.
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.
Levo : En lyftanordning för höjdjustering av manuella gåbarrar
The parallel bars is used in physical therapy and is mainly used for patients who have to train walking and balance after a stroke or an operation. It consists of two long handrails with two legs on each handrail. These legs go down into two ground-plates and are locked at the wanted height with a pin. The parallel bars is an appreciated device and is used on a daily basis in many care units.The main issue with the manual parallel bars is that it is very difficult and heavy for a single person to adjust the height of it. If a larger adjustment of the height has to be done, the legs have to be adjusted one at a time otherwise the they will be locked.
Påskön. Myten om Rapa Nui
This essay will examine the historical picture of the island Rapa Nui as it is portrayed in popular science and in ecohistorical literature of the university of Gothenburg. This historical picture states that the inhabitants of the island cut down a lot of trees in the process of transporting the big and heavy statues, moai, from the quarry to the platforms along the coastline of the island. During this process all trees disappeared and resulted in soil erosion. The cultivation was destroyed and brought hunger to Rapa Nui. The following rivalry for food led to a situation of war followed by a cultural collapse.
Studie och riskanalys av sulfidleror i Uppsala stad
Most of the city of Uppsala rests on postglacial clay with a varying content of sulphur. The sulphur occurs naturally in the clay in reduced form as sulphide and the clay is for that reason usually called ?sulphide clay?. Excavation during construction activities gives rise to large amounts of excavation material, of which the sulphide clay is a considerable part.When the clay is exposed to air and water, an oxidation of the sulphides occurs which may produce an acid leachate and the mobilisation of heavy metals bound in the clay or underlying material. The aim of the work has been to improve our understanding of the behaviour of sulphide clays and produce a basis for risk assessment in the future handling of excavation material with high sulphide content.
Environmental impact assessment of energy recovery from food waste in Singapore : comparing biogas production to incineration
As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.
Cause-related marketing - Välgörande för varumärket? : En studie i hur konsumenter uppfattar CRM i en kritiserad bransch
Background: Increasing globalization has changed the business environment and also resulted in increased awareness of the consumers and demand for higher standards of social responsibility. The companies brand strategies has gain in importance in order to strengthen their brands. A part of a company's CSR, CRM, cause-related marketing, which is a relatively new marketing strategy and created when companies choose to partner with charities and market it. Garment/clothing industry has as many others come to be shaped by the effects of globalization, but has also endured heavy criticism over the years. This criticism is largely because of the outside world's reaction to the exploitation of developing countries.
Utveckling av arbetsmetod för DFA
Scania is among the leading companies in the heavy vehicle industry. Scania also assemble engines for their trucks and buses, as well as to external marine and industrial applications. Wrongly assembled parts leads to quality problems, which makes it important to secure that the assembly is correct. To do this Design For Assembly (DFA) is used to describe how parts should become easier to assemble. Scania?s production unit for engine assembly has had a working method for DFA in the shape of a checklist, which is not used.
