Sewage sludge contains plant nutrients and has earlier been utilised as fertilizer to cropland. Unfortunately not only plant nutrients but also heavy metals, pathogens and organic contaminants tend to accumulate in sludge. The suitability to use sewage sludge in agriculture has therefore been subject to several discussions over the years. The Swedish food industry does no longer accept sludge as fertiliser for Swedish producers. In 1999 the Swedish parliament accepted several objectives for environmental protection. In order to prevent environmental pollution and further exploitation of the earth crust, one of these objectives confirm that phosphorous from sewage shall be recirculated to arable land.

Detection of leukocytes in semen from boars is part of the routine control of semen quality. Leukocytes in semen can cause damage to spermatozoa that leads to impaired fertilization. In the artificial insemination (AI) industry there are standard routines for the quality control of the boars and of the neat semen before use. Since 2001, Quality Genetics has not done the leukocyte examination on semen samples from boars which are used for the production of pigs for slaughter. The purpose of this study was to investigate the occurrence of leukocytes in semen from AI-boars. The questions addressed were whether there are boars that have leukocytes in their semen and how frequently it occurs and, moreover, if there are differences between breeds, or even between individuals whose semen was checked before use in AI-dose production compared to those which were not. The study included a total of 135 AI-boars, of which 67 were Hampshire, 35 Yorkshire and 33 Landrace, all belonging to Quality Genetics AI-station in Hållsta.

This study explores whether environmental, social and governance (ESG) issues affect the monetary value of a company.The samples used in this study have been taken from the Johannesburg Stock Exchange (JSE) in South Africa. Since 2010, JSE have been categorizing companies using the King Code III criteria to establish a Socially Responsible Investment index (SRI index). Companies that fulfill the required number of criteria are classified as 'best performers' using the SRI index.  In this study the monetary value of a random sample of 'best performers' has been compared to the monetary value of a random sample of companies without an SRI index evaluation.This study found that companies without a SRI index have a higher unique risk, which means a lower stock price with a higher dividend yield. Companies with an SRI index evaluation have a lower unique risk, which means a higher stock price and lower dividend yield. In conclusion, this study shows that SRI adjusted companies have an enhanced monetary value in comparison to non- SRI adjusted companies..

Background: Sleep-disturbances in persons with Alzheimer´s disease are prevalent. They are characterized as increased frequency and duration of awakenings, decreased slow-wave sleep, REM-sleep and increase of day-time napping. Depression and lower quality of life are associated with sleep-disturbances. Altogether a significant source of stress for caregivers and an important factor in institutionalization. Non-pharmacological treatment alternatives are rare.Method: Single-case A-B-C design, with non-concurrent multiple baselines, a pilotstudy.Aim: To explore if an educational program on sleep, sleep disturbances and behavioural change directed towards caregivers improved sleep, depression and quality of life in persons with Alzheimer´s disease living at home.

En röststörning kan sägas föreligga då rösten inte fungerar eller låter som den brukar så att det påverkar kommunikationen. Prevalensen för röststörningar uppskattas till omkring 6 % av den vuxna befolkningen. När rösten inte fungerar som den ska leder det till emotionella, sociala och funktionella svårigheter för individen och har negativ inverkan på livskvaliteten. Voice- Related Quality of Life (V-RQOL) är ett självskattningsformulär som mäter vilken inverkan en röststörning kan ha på individens livskvalitet. Detta instrument är internationellt välanvänt, men har inte funnits översatt till svenska.

The purpose with this essay is to find out how aware students are about the environment, andif they believe that their actions can influence the environment. I have used both earlierresearch and questionnaire surveys in order to fulfill the purpose. In earlier research, I haveused research based on materials that are scientific. According to the researchers it isimportant that the children and young people become involved and dedicated to theenvironment and its surrounding world. It is important to listen to the children's thoughts andvisions as they are aware about what happens, but do not reflect on the worst, but hope that itbecomes an improvement in the future.

The future climate of Sweden is expected to become warmer in the future. This would be beneficial for vineyards and may lead to a greater area being allocated for wine production. The environmental impact concerning eutrophication from Swedish vineyards has not been evaluated before. In this study nutrient balances are constructed for four Swedish vineyards with the goal to estimate the out and in flows of nutrient in the systems for the year 2010. Interviews with focus on farming practices undertaken during the year are conducted with the farmers.

Sheep breeding contributes not only with wool, hides, meat and milk but also with openlandscapes. The sheep?s wool is a good raw material thanks to a lot of different qualities as itis water rejecting and easy to form. The wool production today is concentrated to specificplaces in the world which leads to environmental problems and a distorted market. InJämtland, a province in Sweden, there is right now a staking going on for local production andrefining of wool in a project called Ullforum.

Certification systems, that assess companies? work with social and environmental issues, have emerged in an increasing number of industries. Today, there are environmental certifications for the food industry, the forestry, the fisheries sector and several more. In apparel industry, certification for sustainable working conditions has been of major impact. The property sector is no exception from other industries.

To act responsible in relation to environmental, economic and social issues is a trend that is spreading among businesses and their investors. In order to assess business risks, ethical interested investors are calling for open, honest, clear CSR information that can be followed up in corporate sustainability reports. The ability to communicate about risks and to meet investors requests already in the business analytic process can save resources and increase the company?s profitability.The idea that companies should take responsibility for their impact on society from economic, environmental and social perspective is called Corporate Social Responsibility, CSR. In addition to CSR, there is another three-letter abbreviation in this context, PRI ? Principles for Responsible Investment ? which are principles, signed by ethically interested investors.

The task of making a correct application for B- activities is the foundry time consuming task. Information and facts concerning your entire business activity shall be attached into a description of environmental consequences, which will be the basis for the decision making whether the activities shall be granted a permission to practise environmentally hazardous actions or not. When the Environmental Act were established 1999, the permission process became more extensor. With this study I want to give an insight about how these applications are made. The methods I have used to collect information are a study literature where the Environmental Act has been the focus, and qualitative interviews with two County Administrative Board. I used the Environmental Act to understand why permission is needed and the interviews to give me insight in how the work is done. My conclusion is that it is very unusual that an application is granted without complements.

This empirical work and base has been to analyze the new high school reform that the Swedish government introduced as a statement 2008/09:199 about: Higher demand and quality within the high school. This statement became legal through the government vote in spring 2010. But above all it is the investigation (SOU 2008:27) that is the central piece for these new examination changes for high school students that will come into effect 1 of July 2011. The purpose and questions asked in this analyze has been if the reform takes its base in a modernistic (traditional) way or a late modern scientific perspective. And also to find out how these new quality amendments in the investigation makes visible about the high school and what the purpose are about the changes. When scientific theories in these analyze is placed against the reform, the result shows that the modernization process reflects more of a late modern aspect, which constantly reappraise in a changeable society.

Scandinavian Biogas is involved in the planning of a combined ethanol and biogas factory in Karlskoga, Sweden. Besides biogas and ethanol large amounts of digester residues will be produced, about 450 000 liquid tonnes residue (~7,3 % Dry Substance( DS)). The objective of this thesis was to investigate possible uses of the residue from the biogas production process ScandgasEthanol developed by Scandinavian Biogas, and to derive a methodological approach how to evaluate and compare handling systems. Three systems where proposed and compared in this thesis; spreading of the untreated residue as fertilizer (system 1), dewatering to a higher DS content to reduce transportation before spreading as fertilizer (system 2) and production of a solid fuel by dewatering and drying the residue (system 3). The general conditions for the proposed systems were investigated in terms of practical viability, economical aspects, environmental impact and energy inputs/outputs.

The project is a practical and theoretical test of IP telephony with Skype in order to form a base for a comparison between IP-Telephony with Skype and the Public Switched Telephony Network (PSTN). PSTN is the common standard that most of us use for telephony today. The objective for the study is to simplify the choice between PSTN and IP-Telephony for the Swedish private customer user group. The project is supposed to answer the following questions. - How easy is it to start using IP-telephony with Skype? - How is the quality of IP-telephony compared to PSTN? - Are all services provided by PSTN available and accessible using the IP-solution? - How are the usability and the availability of support with IP telephony? - Is IP-telephony a cheaper solution and in that case under which circumstances? Within the project a collection of practical and theoretical tests have been performed to be able to form an opinion on the IP-solution in the following areas, installation, function, quality, usability, costs, accessibility and security.
