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.

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.

During the 2010s were such employees one of the most ill groups in Sweden.This master's thesis in occupational environment development and change management focus on examining the special knowledge an OHS and its clients in one home maker service need to strengthen the workers of the industry and find out how the interaction between OHS and home maker service works and how it could be evolved.A qualitative study was conducted in a Swedish city on the basis of an organizational perspective.
Simulering av översvämningar i Byälven
Severe floods caused by heavy autumn rains in year 2000 raised the question whether measures to reduce the damage from high water levels, in the area surrounding lake Glafsfjorden and along the river Byälven down to lake Vänern, are possible. One option is to reduce flow resistance along the river and thereby lower the maximum water level a given inflow would cause. Good knowledge of hydraulic and hydrological conditions is necessary in order to estimate the effect of such flow-reducing measures. In order to quantify such effect a 1-dimensional hydraulic flow model has been set up for the river Byälven using the software package MIKE 11. The model is more detailed, especially concerning topography and bathymetry, than earlier models used for studies of the river.
Implementation av CUSUM/SPRT-algoritm för kvalitetsövervakning i realtid av robotsvetsning
Under början av 1990-talet inledde Volvo Personvagnar i Olofström en process där övervakning av robotiserad MIG/MAG-svetsning var i fokus. Det ledde fram till ett forskningsprojekt som resulterade i att Stefan Adolfsson, Lunds tekniska högskola/Blekinge tekniska högskola, 1998 presenterade avhandlingen Automatic Quality Monitoring in GMA Welding using Signal Processing Methods [5]. I den presenterades ett SPRT-baserat övervakningskoncept för övervakning av MIG/MAG-svetsning med kort- och spraybåge. För att få fram ett kostnadseffektivt övervakningssystem uppkom tanken att använda vanliga PC-datorer som plattform. De erbjuder hög beräkningskapacitet till förhållandevis låg kostnad.

DISA-metoden : En undersökning om gruppledarnas bedömningar av genomförandet och av metodens framtidsutsikter
Twice as many women as men suffer from mental ill-health. The negative trend of mental problems among teenagers continues. In certain places in Sweden, 40 per cent of the teenage girls have outspoken symptoms of depression. This is why it is important to observe mental ill-health in a public health perspective. One effect evaluation of the DISA method (Depression In Swedish Adolescents) drew the conclusion that this universal depression preventive method is well working. The DISA method includes cognitive behavioural techniques that change negative pattern of thinking, give practice of communication, strategies of problem solution plus exercises to strengthen the social network.

Energiewendes påverkan på det nordiska kraftsystemet
Both the German and the Nordic power markets are seeing dramatically changed conditions due to an ongoing process of expanding the share of renewable production in the systems. For the German part this comes from heavy subsidies which have led to an explosive development in installed capacity of photovoltaic and wind based production. After the Fukushima incident it has been decided to shut down all Germanys nuclear plants. This capacity drop is however not of the same magnitude as the
increase in renewables, but will impact the stability of the power system. The Nordic power system which already has a surplus of power sees an even further increase, coming mainly from construction of new nuclear plants in Finland and a general increase in wind farms.
