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.
Beräkning av ASME-flänsar enligt EN-standard
In this thesis, a transparent model of the human head has been constructed which was filled with a substance that represented the brain. This model was later crash tested. This was done in order to examine how a transparent model of the human head can be constructed to generate accurate data from crash tests. It was also done in order to examine how impacts on the front of the head can deform the rear of the brain. When a head is decelerating, the brain moves forward inside the skull and may hit the front of the skull.
Att arbeta med webbaserad sfi-undervisning : Sfi-elevers syn på internetbaserad undervisning som komplement till lärarledda lektioner
What are the basic thoughts formulated in the Heraclitean fragments? A cosmology, a philosophy of nature, the idea that all can be reduced to a single substance? There is always a risk that Heraclitus is fitted into a thought pattern he doesn?t belong to, if we ? from our present horizon ? focus on continuity in an attempt to frame his thinking as part of an overall progress, running from the so-called pre-Socratics to Aristotle, in the history of philosophy. If we picture the dawn of Western civilization as an early development of scientific thinking, built on a gradual and continuous growth of knowledge, we will easily go astray as we try to discover the Greek origins of philosophy. Assuming, for example, that the readings of Heraclitus as a natural philosopher have come to a dead end, can we approach the fragments from a different angle?The aim of this paper is not to give a systematized reading of all the remaining fragments of Heraclitus, but neither to necessarily contradict the various interpretations that emphasise how these shattered remains reflect a coherent philosophy.

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.
Energy efficient storage of biomass at Vattenfall heat and power plants
Storage of biomass is often associated with problems such as heat development, dry
matter losses and reduction of fuel quality. The rise in temperature can potentially
cause a risk of self-ignition in the fuel storage. Moreover, emissions from storage piles
can cause health problems in the surrounding. The dry matter losses and reduction of
fuel quality can have economical effects. The aim of this thesis project is to develop
guidelines on how to store large amount of biomass at Vattenfalls heat and power
plants in an optimal way.

Case Management : Sjuksköterskans uppfattning om arbetsmodellens effekt för patienter med missbruk och samtidig psykisk störning.
Syftet med denna pilotstudie var att beskriva hur sjuksköterskor som arbetar som Case Managers uppfattar effekterna av denna arbetsmodell avseende medicinsk vård, social situation, missbruk, vård- och omsorgskvalitet samt samordning för patienter med missbruk och samtidig psykisk störning. Metoden var kvantitativ och genomfördes med en webbenkät. Resultatet visade att respondenterna anser att Case Management haft en positiv påverkan på patienternas medicinska vård och sociala situation. Det ledde också till en bättre kontakt med patienten, och förbättrad bedömning av patientens sammansatta situation. Sammantaget framkom en övervägande positiv uppfattning även av vård- och omsorgskvaliteten, samordningen och de arbetsmetoder som använts.

Bevattning av lagrat virke vid svensk skogsindustri : omfattning och miljökonsekvenser
Most of the saw and pulp industries have stored wood nearby their production, the main
reason is to have a continuous wood flow to the production. Wet storage of wood is of great importance to keep the wood quality. Without water sprinkling the risk of drying outand decomposition through biological activity increases significantly and will result in a negative effect on future production and quality.
One drawback of wet storage of wood is the leaching of chemical substances into the
surrounding recipient. The log yard run-off contains phosphorus, nitrogen, phenols and
organic substances. These substances can cause problems for the surrounding environment.
The main objective of this project is to gain an understanding of the wet storage used by the Swedish wood industry and estimate the environmental consequences that run-off water will have on the recipient.
Kränkande behandling via sociala medier : En kvalitativ studie om skolpersonalens syn på kränkande behandling via sociala medier
The aim of this study is to examine if and to what extent the personnel at the local school perceive offensive treatment through the social media among the students and what the personnel thinks about the responsibility of the school to prevent this type of abuse. Offensive treatment through the social media has become a common occurrence among youth and affects health in both psychological and physical ways. As offensive treatment through the social media often takes place outside of school in the students spare time the responsibility of their health is unclear. But since it affects their school results the school has a responsibility to act, which is confirmed by legislation. However, the legislation does not mention offensive treatment through the social media and the school has no distinct guidelines to prevent this form of offensive treatment.
Robin Hood och Hemtjänsten : En förstudie om Företagshälsovårdens arbete med arbetsmiljöfrågor inom hemtjänstbranschen
Occupational Health Service (OHS) has an important role in society. It is designed to prevent illness and strengthen the health of workers. OHS operations and development are currently being studied at the School of Technology and Health at the Royal Institute of Technology in Sweden. One of the industries studied is the home maker service. 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.
