Kvinnors och mäns motiv och ambivalens till att donera ägg och spermier i Sverige

Involuntary childlessness is a big problem around the world. One way to solve the problem is to receive oocytes or semen from a donor. In Sweden, semen donation has been regulated by law since 1985 and oocyte donation since 2003. The aim of this study was to investigate what motivations women and men in Sweden have to donate gametes, if they feel any ambivalence to donate, and to compare if there is any difference in motivation and ambivalence between women and men.

Askans inverkan på beläggningstendensen i ett biobränsleeldat kraftvärmeverk och växtplatsens påverkan på askegenskaperna :

This report was written by Sofia Ericson and describes the degree thesis with the title: ?Connections between the growing site of bio fuel, the chemical composition of bio fuel ash and the deposit growth in a bio fuel fired boiler.? The purpose of this degree thesis was to avoid melted deposit growth in the bio fuel fired boiler at ENA Kraft in Enköping. Potassium and sodium are known to lower the melting point of bio fuel ashes and are therefore not wanted in the trees in higher amounts than necessary for the growth. Silicon is also known to be important for the deposit growth but it is not possible to say in general if higher or lower contents of silicon is better. The relation between silicon and other chemical substances is more important than the total amount of silicon.

Mer än ett pris - : En studie om information, uppfattningar och användning av internpriser.

Background: When companies decentralize their operations into profit centers, transfer pricing often becomes an integral part in intracompany trade. A profit center may affect both revenues and costs and seek to maximize profit.

Vattenkvalité i Märstaån : Igenväxning som indikator på närsaltläckage och vattenstatus

The purpose of this study was to examine whether an inventory of the vegetation overgrowth could be used to indicate a locally nutritional impact. The study was conducted at Märstaån where the water runs through a number of agricultural lands that could lead to an increased amount of diffuse emissions of nutrients. The vegetation overgrowth in the water was also studied in relation to shade, meandering and water flow effects on the vegetation. With this method, no definitive conclusions could be drawn.Where the water was shaded, no vegetation overgrowth could be found. Therefor trees should be planted to prevent any future overgrowths.

Effects of ten year old enrichment plantings in a secondary dipterocarp rainforest : a case study of stem and species distribution in Sabah, Malaysia

Large areas of forests in the tropical region have during the last decades been lost and converted to new land uses while other areas have been degraded into secondary forests. These secondary forests need to be restored and rehabilitation through enrichment planting and liberation may help to speed up the recovery process. The objective of this thesis was to evaluate a rehabilitation method that includes enrichment planting, slashing of weeds and girdling of unwanted trees. The site for the project is situated in Sabah, Borneo in a secondary forest which had been logged and burnt by a wildfire. The project?s goal is to rehabilitate and increase biodiversity through enrichment planting of seedlings mainly belonging to the family Dipterocarpeaceae (dipterocarps).

Föryngringsresultat och beräknad virkesproduktion i naturligt föryngrade tallbestånd i Västerbotten under mitten av 1990-talet :

According to the Board of Forestry, in Västerbotten, many natural regenerations of Scots pine (Pinus sylvestris) carried out on privately owned forest in the middle of 1990 in Västerbotten have rendered a bad regeneration outcome and will provide a low future forest production. The Board of Forestry believes that the negative result can be explained by the fact that the regeneration has been carried out in wrong locations and that scarification failed to work as planned. In order for an accepted rate of regeneration the guidelines of the Forrest Act require, not less than 10 years after final cutting at natural regeneration, that there should be at least 1300 (site indices 16 m) - 1700 (site indices 20 m) main crop stems per hectare. Main crop stems are defined as stems according to the place of growth and appropriate tree type, in addition with regard to quality, stage of development and damage risk have a prospect of succeeding. In addition main crop stems should be separated by surface so that the proportion sample plots with 3 meters radius, and lack main crop stems, are not more than 10 % of site indices 14 meters or higher.

Kärnkraftens värde i framtiden : en jämförelse med kraftvärmeteknologi från biobränsle

The debate on the future of Nuclear power in Sweden has increased with the discussion on global warming. The uncertainty of fossil fuel- and carbonprices the latest years has aroused considerable interest in Nuclear from power companies, industry and politicians. Nuclear power plants have negligible CO2 emissions and are not directly affected by increased price of emission rights and fossil fuels. The future power production needs to reduce its emissions of greenhouse gases to become sustainable. The purpose of this study is to examine the value for power producers to have the option to invest in Nuclear power and how a Nuclear power venture would affect future electricity prices. The study uses two methods, a traditional cash flow model and real option analysis, to estimate the value of Nuclear power.

Goda levnadsvillkor eller skälig levnadsnivå... efter 65 år : En jämförelse av omsorgsmodeller enligt LSS - lag om stöd och service till vissa funktionshindrade och SoL -socialtjänstlagen

The level of help and support given to elderly people over the age of 65 has been regulated by two separate laws; 1-the Act concerning Support and Service for Persons with Certain Functional Impairments (LSS) and 2- Act of Social Services (SoL). Recent changes in the legislation could cause local authorities to deal with these issues in different ways. The aim of this study was to examine and evaluate possible differences in the level of support for the elderly, dependant on which of the two laws was used in the decision process.The questions raised in this paper are· What are the major differences in the purposes of the two legislations?· How will the decisions be influenced dependant on what law is used? Do the decisionmakers identify the difference between the quality levels "good" and "fair"?· How is the process of care organised and managed within each of these legislations and how is the personnel used?· Are there differences in quality regarding freedom of choice, your own right to decide, influence, comprehensive view and continuity in the efforts given?· What development can you see in these fields of care.As a method I have used a case study involving four big cities in Scania. The most interesting and essential knowledge in the study was obtained from qualitative interviews with eleven decision-makers in the four communities.The result of this study indicates that there are more similarities than differences in the purposes of these laws.
