I studien har nio respondenter intervjuats, vi anser att de personerna har varit relevanta för studiens syfte. Resultatet har analyserats med hjälp av tidigare forskning och teorier inom ämnet.Resultatet visade att det skulle vara ekonomsikt, miljömässigt och tekniskt möjligt att starta upp petroleumtransporter till norra stockholmsområdet.

Cambodia is located in Southeast Asia with a tropical monsoon climate and distinctive wet and dry seasons. Poverty is a widespread problem in Cambodia and 30 percent of the population were classified as poor in 2009. About 80 percent of the populations live in rural areas where poverty is an even greater problem. In agriculture, rice cultivation is dominating and the crop is cultivated on 85 percent of the arable land. Livestock keeping is also a traditional part of Cambodian agriculture.

This thesis concerns how the power quality in the grid is affected by the connection of wind power plants. As things are at present, Fortum Distribution AB has a number of wind turbines and wind parks connected to the own grid. As the pressure on building and connecting additional wind power is increasing, so is also the interest of how the already existing wind power generation affects the power quality in the nearby distribution grids. The study is performed by direction of Fortum Distribution AB and is limited to the 10 kV/40 kV-grid in Bohuslän, Sweden. The methods for calculation of power quality are compared to the results of a number of measurements.

The music distribution in Sweden and the world is rapidly changing. The music industry, however, has been reluctant to change the way they distribute music. The consequence has been that illegal music files have been available for downloading to anyone with an Internet connection. Because of the illegal downloading a new law have been implemented in an attempt to stop this behaviour. Our theory is that in implementing the IPRED-law, the sites that were hosting most of the illegal material will experience a severe decrease in traffic.

The purpose of this paper is to examine how the relationship between the socially constructed genders is manifested in American library science. To visualize gender, bibliometric analyses of peer reviewed articles published in three core journals of library science between 1980 and 2000 inclusive, are performed. The three journals are: College and Research Libraries, Journal of Academic Librarianship and Library Quarterly. Questions: 1. Does gender affect the publishing process regarding the distribution of female and male authors? 2.

The population growth and urbanisation in low-income countries bring issues of poor living standards and miserable sanitation conditions onto the agenda. If well-functioning waste management systems were developed, this could master some of the problems. The already existing local informal waste handling system that is common in many low-income countries, needs to be developed with proper sorting and composting solutions to decrease the environmental burden and improve the overall situation in the dense cities. This master?s thesis project is performed with the intention of developing functional decentralised waste management units in the city of Pune, India.

Changes in the environment are affecting the world market, and pressures from several stakeholders? are forcing different enterprises to adjust to the current situation. Farmers? difficult working conditions and environmental impacts of the conventional cotton production in India have been highlighted. The small-scale production that is characterising India?s cotton farmers implies an insufficient competition power.

A change towards using more biofuels than fossil fuels is taking place in Sweden, and in many other parts of the world. This makes the use of fuel pellets increasingly popular, causing a greater demand for sawmill sawdust products. There is a trend towards the use of multiple types of shredders, instead of a single type in each sawmill. The purpose of the study was to characterize the different flows of saw particles that can be found at Sävar såg when cutting thick or thin wood with different cutting techniques. The saw particles size, shape, moisture content and heat value were analysed by the cutting stations: first cutting fast and slow, second cutting fast and slow, grading fast and slow and planning.

Introduction: Public health researchers have long been focusing on investigating health inpopulations through determinants such as income inequalities. Nevertheless, incomeinequalities can be considered an effect of the organization of welfare regimes. The publichealth status is largely affected by the organization of welfare regimes and consequently thereare large differences in health within and between welfare regimes. How are these differencesdistributed and how can they be explained?Aim: To compare health between welfare state regimes with the use of Esping-Andersen?swelfare regime typology and to investigate the relationship between welfare statedeterminants and health.Methods: A literary review based on 12 scientific articles.

The Swedish energy system will be influenced by many future changes, such as energy and climate policy objectives. The installation of more renewable electricity could increase by using solar energy. Over the recent years, grid-connected photovoltaic (PV) systems have increased dramatically in Sweden, partly due to various support systems and compensation models. These support systems have been designed to make it easy for individuals and businesses to invest in self-generated electricity and thus contribute to the transformation of the energy system.The introduction of a higher proportion of solar energy may in turn affect the Swedish electricity system. This could mean that the electricity companies will be facing a number of changes in the near future.

Chlorinated solvents are common contaminants in soil and water. Under anaerobic conditions microbes are capable of transforming chlorinated solvents into ethylene which would result in a remediation of the contaminated area. In order to use natural attenuation as a remediation method evidence of continuous degradation is required. Furthermore, the degradation must occur at a sufficient rate and continuous monitoring of the site is needed until the demanded levels are achieved. A field study was performed on the basis of data from a dry-cleaning facility contaminated mainly by perchloroethylene.

This thesis investigates the overall risks of flooding over the Design Basis Flooding Level (DBFL) at the Swedish nuclear power plants (Oskarshamn, Ringhals and Forsmark), using statistical data and methods, but also considers historical events which might affect the overall risk of flooding at the specified sites.Considering the nuclear accident which happened in Fukushima in conjuction with the earthquake and tsunami which struck eastern Japan on 11 March 2011, operators and licensors of nuclear power plants all over the world conducted reviews and investigations on the overall risks posed to the plants from external events. One important such event is extreme water level.One part of the thesis includes an extreme value analysis (using Generalized Extreme Value distribution and Generalized Pareto distribution) of water level data from SMHI (Sweden's Meteorological and Hydrological Institute) measured at stations close to the Swedish nuclear power plants. The results of the statistical studies indicate that considering the return period used in the thesis (100 000 years), the water levels at the Swedish nuclear power plants are not expected to exceed DBFL.The other part of the thesis consists of a historical study of extreme weather-related events. The results of this study indicate that no historical events seem to have occured which would indicate a higher risk of flooding than the one suggested by the statistical study. .

A severe profitability decline in sugar beet production in all of Europe is one of the consequences of the latest reform of the EU sugar regime. In south of Sweden, sugar beets is the crop that has been the most profitable by far for the last decade. The high profitability has contributed to the high rate of increase in the price of land and has restrained the structural change towards a more effective agriculture. Because of the reform, all sugar beet producers are facing diminishing income and must find ways to compensate this. The aim of this master thesis is to study how Swedish farmers adapt to the sugar beet reform. A questionnaire was sent to 354 randomly selected sugar beet producers.

The problem with passive farmers has arised as an effect of the European Union´s common agricultural policy (CAP) and the decouplement from production-based payments. Payments to passive farmers contradict the purpose of the single payment scheme and constitute a great cost for the EU. The new contractual period after 2013 has given rise to discussions on the direction of the CAP with a purpose of increasing the efficiency of the single payment scheme, and reducing passive farming. The aim of the study is to increase the knowledge about a few factors? influence on passive farmers? attitudes towards land use and the CAP.
