OTEC-Ett energialternativ för enhållbar ö

Ocean Thermal Energy Conversion (OTEC) is a technology that utilizes the temperaturedifference in oceans between the warm surface water and the cold water at 1000 m depthto produce electricity. The purpose of this report is to investigate if OTEC with its synergiescould become a commercially feasible energy solution for a small island. A literature reviewis conducted to explore the different OTEC technologies and to what extent the threesynergies; fresh water, air conditioning and aquaculture, could be used. In order to calculatethe profitability of these synergies there is also a study conducted on the conventionalmethods and cost of fresh water production, aquaculture and air conditioning. A model is setup using a scenario of a small tropical Island with population of 100 000 people.

Teknisk och ekonomisk analys av en bränslekonvertering vid SIA TallOils pelletsfabrik :

At SIA TallOil's pellets factory in Latvia wood shavings and saw dust are dried with flue gases from a gas burner. TallOil wants to replace the gas with a biofuel that is available at the pellet plant. The reason for this is the unstable gas market in Europe in combination with the fact that TallOil wants to improve its profile as supplier of renewable bio fuels. In this project the technical and economical possibilities for a fuel conversion to ether bark powder, wood shavings or wood powder have been investigated. These fuels should be burned in one of the following applications: TPS BioSwirl, VTS Multifuel burner or Saxlunds bio fuel combustion plant Due to the fact that the fuel alternatives available are relatively common except for bark powder, the work has mainly been focused on bark powder.

Utveckling av arbete med ständiga förbättringar: en fallstudie vid Akzo Nobel Surface Chemistry, Production Surfactants i Stenungsund

Den ökade förändringstakten i samhället på grund av ny teknik, internationalisering och att samhället blivit alltmer mångkulturellt bidrar till att större krav ställs på företag att hela tiden förbättra sin verksamhet. Akzo Nobel Surface Chemistry, Production Surfactants i Stenungsund, har huvudsakligen sina kunder och konkurrenter runt om i Europa. Då Sverige ligger i utkanten av detta område tar det omkring en leveransdag längre tid för Production Surfactants att leverera sina produkter i jämförelse med företagets konkurrenter. Detta medför att Production Surfactants behöver kompensera denna längre leveranstid genom exempelvis högre produktkvalitet, större flexibilitet eller lägre priser för att ha möjlighet att tävla på marknaden. För att uppnå detta behöver Production Surfactants utveckla och systematisera sitt förbättringsarbete.

Slimmade möten, en undersökning av Leans påverkan på mötesprocesser

Lean has been studied intensely since the 1980s and it has been tested and successfully implemented in a wide variety of businesses. This thesis aims to examine the potential effects of a Lean implementation on meeting efficiency, a topic that has gotten little attention in the research community. First, a number of meeting problems are introduced, as they are perceived from the company that is the subject of the study. Second, the potential of introducing Lean in a meeting process is evaluated using the Lean Thinking principles. Third, the wastes that are generated from the meeting problems are identified.

Psykosocial arbetsmiljö : kommunikation och trivsel i industriella arbetslag

Relationships and trust between humans create the psychosocial working environment. This is a basic human activity and is communicated in a continually ongoing process. Conciseness about the value of trust and social capital motivates the need for work, with threats to communication, being conflicts and noise. This can create greater trust in the workplace as a whole, as well in the working team. Scientists are increasingly interested in these social relations in the working environment; there are profits, both for production and in terms of individuals2019 well being, in shifting the focus away from a purely production-oriented, economic perspective.

Den mobila prefabriceringsfabriken : Ett nytt produktionskoncept

This is an investigation of a mobile prefabrication factory´s competitiveness and profitability which also will result in a suggestion for a design of the factory. The mobile prefabrication factory is an idea of a new concept for production which is meant to be used in the manufacture of slab. The main intention with this concept is that by using a fast established prefabrication factory to produce elements near the construction site, thus avoiding transport from the factory to the building site. This means not only an environmental and economic gain, but also that you can avoid risking damage the elements which often occur during transportation. The contractor is owner of the mobile prefabrication factory and can thus avoid long waiting times and cyclicality.

Dold mångfald i den öppna demokratin? Om diskriminering på grund av sexuell läggning bland förtroendevalda kommun- och landstingspolitiker

Groups that are often referred to as being dismissed in society in general is by some aspects also considered being so in political arenas. A recent compilation of existing research over structurally based objections of gaining power and positions within Swedish parliamentary politics highlight a lack of research considering whether sexual orientation could be such a discriminatory basis. Using a queer theoretical approach, and drawing on concepts such as heteronormativity and homophobia, the principal aim of this essay is to illuminate aspects of local parliamentary political areas where discrimination on the grounds of sexual orientation become relevant. In order to do so six in-depth interviews with homosexual politicians have been conducted. Finding a queer potential in certain ideological parliamentary political environments that enable homosexual politicians to be open about their sexual orientation, it still relies upon the individual to be confident enough not to interpret the political context as homophobic and heteronormative..

Ärtrev som substrat för biogasproduktion : En litteraturstudie och rötning i labbskala

Until 2020, 49% of Sweden's use of energy must derive from renewable sources. Greenhouse gases must as well decline with 40% compared to 1990 as a part of Sweden's 16 environmental objectives. Biogas is part of the effort to achieve these objectives, but as the demand for biogas increases, more substrates are needed to meet the demand. The purpose is to investigate the conditions for pea residue as substrate by performing lab-scale mesophilic digestion with different fractions and notch lengths and then to summarize pea residue as a substrate for biogas production. During anaerobic digestion, 1000 ml bottles were used as reactors for digestion.

Utvärdering av effektstyrningssystemet EnergiDirigent® ur ett miljöperspektiv

Energy Director is a control and measuring system for energy consumption and is part of the product portfolio of E.ON AG for more efficient use of energy, offered to business customers. As of today, the system has only one parameter of control, namely power, and the objective of this essay has been to investigate whether other ones could be added. The emphasis is on the environmental perspective, which is why carbon dioxide has served as an example for this parameter in question.Parallel with the study of Energy Director electricity on the margin, calculations of carbon dioxide equivalents and also the Swedish trade of electricity have all been highlighted. Results indicate that when reductions in energy are made it is endorsed to omit from electricity on the margin rather than some mean distributed electricity, under certain conditions, and in addition the calculations of the reductions should be modified regarding the efficiency of the power stations fuelled by lignite and bituminous coal. Sweden practices trade with the Nordic countries as well as Poland and Germany.

Methane emissions from Swedish sheep production

The quantity of methane emissions from sheep depend on several factors, for example, the composition of the diet, feed quality, the age of the animals, time of the day and maybe also breed and sex. A comprising literature review was made about which factors that affect the size of emissions. In addition, a questionnaire was sent to two farms, one with a more intensive production system and another with a more extensive system. Inventories of the two farms were made; the rest of the data needed to conduct the study was taken from literature and other sources. Meat produced at the more intensive farm caused emissions of 0.4 kg of methane per kg of bone free meat and the more extensive farm caused emissions of 0.9 kg methane per kg of bone free meat.
