Biogasanvändning vid Käppalaförbundets Reningsverk: ? en värdering av miljöeffekter
This thesis calculates and compares the values of improved environmental quality due to future possible investment alternatives in biogas production facilities at Käppalaförbundets Reningsverk (Käppala Sewage Treatment Works) in an attempt to determine which alternative yields the highest such value. Käppala faces three investment alternatives for the usage of biogas. The alternatives are production of vehicle fuel, district heating and thirdly, heat and power production. Estimates of the value of environmental change are calculated for each of the three investment alternatives, and these estimates are then compared. The environmental change in question is the change in discharge levels of carbon dioxide (CO2), nitrogen oxides (NOx), sulphur dioxide (SO2) and particle matter.
Omsorgskvalitet i äldreomsorgen : Ett begrepp i utveckling
This study is based on interviews with heads of unit, care staff and senior representatives from a total of six people. We have in this study directed our focus on care quality in the elderly as a concept in development. It appears, when the elderly do not have any dependents, it is even more important that staff supports some extra where no relatives are involved.Quality of life is the broader concept of good quality care and where a good quality of care is a necessary condition for a good quality of life. According to the social services care is the target that older people will live a good life and be allowed to live in a safe environment, which we intend to investigate in this study. Opportunity for greater influence should now be given to older people and their families on how interventions should be designed and implemented.
Mjukvarukvalitet i öppen programvara - en explorativ och kvalitativ studie av uppfattningar om mjukvarukvalitet
Open source software has recently been discussed, not least in media as a revolution in IT. A number of advantages have been listed in changing proprietary software into open source software. Examples of such pros are no expenses for license fees and improved efficiency. In spite of this, few users have made this change. One of the reasons is a distrust of the quality in open source software.
Frekvensreglering i det nordiska kraftsystemet
Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.
Utredning av frekvensregleringens påverkan på mekanisk utrustning i en kaplanturbin
As a consequence of increasing wind power installations in the Nordic grid the last years, the need for regulating power has become larger. In the Nordic grid, regulating power is mainly provided by hydro power. One part of the regulating power is called frequency control, which ensures that the grid frequency is stable and close to 50 Hz.However, setting the turbine into frequency controlled operation may cause stress and wear of the components in the mechanical control system. Frequency controlling implies large and frequent servo forces and longer travelling distance of the sliding bearings in the Kaplan turbine.Based on one selected Kaplan turbine, Selsfors G1, measurements and MATLAB calculations have been performed in order to determine forces and movements of the linkage system. With these forces and movements as input, stresses and fatigue have been determined as well as sliding distances, bearing pressures and wear of bearings during a typical lifetime of 40 years.The results indicate that no severe wear exists on the bearings during 40 years of service.
Kvalitetsarbete med värdeskapande i fokus : En kvalitativ studie av socialpsykiatriska boendet Pilbacken
There is a lack of research in the field of quality improvement efforts based on profound knowledge in social services. The current situation is therefore a significant knowledge gap in terms of studies of this type of systematic quality work and how it is applied in practice. This study therefore intends to describe Pilbackens quality work and further examine if the profound knowledge is consistent with quality work in microsystems by an analysis of Pilbackens work. The present study has been performed by a qualitative method and the material is collected through semi-structured interviews. In order to analyze the study?s result have profound knowledge and the model microsystems been used.
Visst gör det ont när möten brister : En kvalitativ uppsats om fyra före detta klienters upplevelse av mötet med myndighetsutövare och institutionalisering som behandlingsmetod
The purpose with the essay is to illuminate four former clients? personal stories about the meeting with the authority in the Swedish welfare system and the institutionalization theywent through. The questions being asked in the essay focus on communication, the relationship concerning power and the former clients attitude towards the institutionalization as a treatment. Four interviews were held with former clients who were institutionalized sometime between the ages of 15-25. The results were then analyzed by theories focusing on communication as a way to gain power and how social interaction may influence the individual attitudes towards authorities.
Webbaserad realtidsuppföljdkvalitetsundersökning
Swedish school has for the last decades been using quality management as a method for improvement. Quality management is an enormous work and the whole school staff needs to be involved. The management consists of several parts like planning, surveys and interviews, analysis of the replies and setting up new goals. Parents, children and teachers are nowadays accustomed with quality surveys. The last few years these quality surveys have been computerized, but they still look almost the same, using little interaction with the respondent.I have had the opportunity to work with the company KMF Ventures, which has a vision that entails a more interactive web survey.
En teori om konsumentmakt- Marknaden som en lösning på demokratiunderskottet?
How effective is consumer power? Can consumers regulate corporate behavior?And if so is the case, could the mechanisms where consumers regulate corporatebehavior have any democratic value to contribute with? These are the questionsthat this master's thesis comprehends with. The purpose of this writing is toconstruct a theory of consumer power that is compatible with democratic theory,this in order to contribute to the ongoing discussion within the discipline ofpolitical science about the third democratic transformation. A discussion that hasbeen actualized due to the democratic deficit created by the growing corporatepower and the shift of power from state to private enterprises. Besides showingfor a parallel between the democratic mechanisms that exists in the relationbetween citizens and state on the one hand, and the consumers and corporationson the other hand, this paper argues that consumers do have a great potential inregulating corporate behavior towards a higher social responsibility andawareness.
Kundnöjdhet i revision: En jämförelse mellan företag som reviderats av Big Four och företag som reviderats av någon annan revisionsbyrå
The need for auditing originates from the agency problem that arises due to the separation of ownership and control in companies. The purpose of the audit is to increase credibility of the financial statements that management uses to communicate with owners and other stakeholders. In order for the audit to fulfill its purpose a certain level of quality needs to be obtained. The auditor can also be seen as a provider of a commercial service in which service quality is important. Audit quality can thus be separated into technical quality, which is defined as the probability that the auditor both discovers and reports a breach in the client?s accounting system, and service quality, which relates to the provision of services in general.
Lämpliga områden för vindkraftsetablering på land i Norrbottens län
Wind power is becoming an increasingly important source of energy. There are several national and international goals set to increase to amount of renewable energy, and in order to meet these goals, the wind power production plays an important part and the establishment of new wind power farms are required. The Swedish national project Riksintresse Vindbruk has appointed areas in Sweden suitable for wind power, mainly when looking at the physical wind conditions of the area. In this study, I aim to define suitable areas for wind power establishment in Norrbottens län. In order to reach this goal, a critical regional method was developed and completed using GIS.

Furthermore, the user's search strategy was also studied to see whether it varied depending on the placement of an ad. An experiment was conducted where 20 subjects searched for articles in a Swedish online newspaper while their eye ovement was recorded with a headmounted eye?tracker. In each search task the online newspaper contained either a low quality ad or a high quality ad.
Ett folkstyre i förvittring eller fortsatt demokratisk livskraft? En studie av de norska och danska maktutredningarnas slutrapporter
AbstractThis paper is a comparative study of the final reports of the Norwegian and Danish power studies performed in 2003. While the Danish study found that democracy is thriving, the conclusion of the Norwegian power study was that democracy is in a crisis. The purpose of this paper is to find explanations to why the studies in two Nordic countries arrived at such different results.Methodologically, the paper consists of an ideological text analysis and critical analyses of the discourse. In order to study how the results of the power studies can differ so considerably, the following aspects have been surveyed; 1) external contexts (government inquiries); 2) work process (the researchers? background, role and co-operation); 3) the problem areas and themes studied; and 4) power perspectives.
Fruktkvalitet inom äppelodlingen : en studie av och för Äppelriket Österlen
The main purpose of this Master Thesis has been to investigate issues concerning apple fruit quality in orchards of Äppelriket Österlen. The goal has been to develop a document, for future benefit towards growers and company management in the production of high quality apples.In order to investigate main issues of fruit quality, focus has been on statistics concerning apple varieties, age of the apple trees, new planting, orchard size and growers opinions. Nine growers have been interviewed to investigate opinions and contribution of different growing techniques to increased fruit quality.
The investigation showed high age of the trees in production and low rate of planting of new trees. Differences in fruit quality were highest between small orchards. Most growers were satisfied with their fruit quality and with their own measures made to improve it.
