Utvärdering av förbättrad metod för objektiv kvalitetsbedömning av spermiemotilitet hos hingst :

In this trial we used QualispermTM as an objective method of measuring stallion semen. Samples of semen were analyzed before and after centrifugation. Motility and concentration were statistically analyzed. During the trial all the objective mesaurments were compared to a subjective method. The advantages of QualispermTM compared to older CASA- systems is it´s ability of measuring a greater amount of spermatozoa while it also grades them into different subpopulations. These subpopulations have different qualities that decides their capacity of fertilization. The results showed that this objective method might be used practically. Although, there are still some disadvantages, such as high costs and the necessarity of accurat training of the handler. If it´s possible to prove further relevant results that also are statistically correct, this could prove the usefulness of QualispermTM as an objective measurment method in the daily work at gestuts and stallion stations, thus giving the staff a reliable instrument in assisting the work for an improved horse breeding in Sweden, improving both in quality and economically..

Klimat i miljökonsekvensbeskrivningar : hantering av klimatförändringar och extrema väderhändelser i MKB

There has always been global warming on earth and it is because of it that the earth is inhabitable. Without global warming the temperature on earth would be around -18 ° C instead of today's + 15 ° C. Global warming is generated by greenhouse gases like carbon dioxide and methane which trap long wave radiation in the earth's atmosphere. The problem today is that the global concentration of green house gases has significantly increased since the 1750's as a result of human activity. Today's values widely exceed the preindustrial values.

Det medeltida Fårö : en empirisk studie av tre husgrunder på en medeltida ödegård

The aim of the study was to through empirical studies interpret the relation between three partially investigated house foundations, on an abandoned farm in Langhammars on northern Fårö. This relation focused upon two main questions; the time of use and the spatial distribution of the archaeological finds.Trough comparative analysis two of these houses can establish to have been contemporary, the third one is too roughly examined. A discussion about the hypothec idea of two or three contemporary farms was made with a negative result.In house 1 smaller processing of tools of flint has taken place near the fireplace in the larger room. A concentration of pottery was also visible near the fireplace, likely to be connected to cooking and eating. The smallest room in the northeast part of the house could have functioned as a storeroom and/or held workshop activities.The archaeological finds and the distribution of it, strongly indicates that house 1 mostlikely consisted of a dwelling house and house 2 functioned as a workshop; linked to activities with handicrafts.

Nutrient efficiency in Swedish dairy cows fed total mixed rations or partial mixed rations

The relatively poor economy in European dairy farming might be improved from efficient feeding systems and dietary management. Increasing herd sizes and transition to loose housing systems in Sweden, increases the possibilities for other feeding systems than separate feeding that is the traditional feeding system in Sweden. Other possible feeding systems are partial mixed ration (PMR) and total mixed ration (TMR), where the TMR system sometimes is associated with overfeeding and thereby increased environmental impact and high feed cost. Diets providing nutrients above or below animal requirements are considered as unbalanced, which in turn are associated with reductions in health, fertility and milk production. On the other hand, a balanced feed ration improves feed efficiency, nitrogen utilization and profitability.

Nyckeln till den positiva spiralen - En studie av musikers syn på sitt övande

Title: The key to the positive spiral - A study of musicians views of their practicing. The purpose with this paper is to make clear how continuous practicing on one element affects not just the specific part but also other things. Is it possible to find a positive spiral where everything can be better if you focus your practicing on one thing? Can this element if it is done daily in a qualitative way transform to a key which will help you to unlock the door to the positive spiral? Are there more keys to find? I am going to reflect my ideas in this paper through a philosophical, psychological and the brain sciences perspective. Quality in action is going to be compared with the quality that you need to set a successful goal, and to reach the state of mind called flow you will need both these qualities.

Böklåda med torv på rastgårdsytan i ekologisk slaktsvinsproduktion : effekter på beteende och emission av kväve (NH3 och N2O)

In organic animal production, synthetic amino acids are not allowed. Therefore, a higher level of crude protein is needed in the diet to pigs, which lead to more nitrogen (N) excreted in the faeces and urine. N can be emitted to the air in the form of e.g. ammonia (NH3), which contributes to eutrophication and acidification and as nitrous oxide (N2O), which is a very potent greenhouse gas. The emission of N can be reduced by e.g.

Gemensam konstruktion av förståelse i samtal som involverar personer med demenssjukdom

Dementia may cause difficulties in communicating. People suffering from dementia are therefore often described as being unable to take part in meaningful conversation. The responsibility to create understanding in a conversation is shared by all participants. By means of different strategies, participants in conversation can construct understanding through collaboration. How these strategies are utilized in conversation where one or more of the participants suffer from dementia is relatively unknown.

Riskbedömning och naturligt producerade dioxiner

The highly toxic man-made substance referred to as dioxin (polychlorinated dibenzo-para-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs)) causes severe health damages both to humans and other organisms, with lethality as its worst. Because of the toxicity several risk assessments has been performed on dioxins trying to determine at what concentration there are no risk of exposure. Resent years of research has discovered that these substances are not only anthropogenically but also producedin natural processes, like volcanoes and forest fires. To investigate if there is a need to take these naturally formed dioxins into account in the risk assessment processes, interviews with persons at relevant institutions in Sweden has been made. Analyses of existing risk assessment methods and political documents were also made to complete the picture.

Implementation of a quality management system in food production

The aim of this study was to investigate how the process of implementing a quality management system for food safety was handled in four different food producing companies in Sweden. The aim was also to analyze what difficulties the companies face and the possibilities that arise when certified. Furthermore, the reason for implementation was discussed as well as the main expectations on the certificate. Implementing a quality management system is a good way of ensuring the quality and hygiene of the food production and it also increases the traceability of food products through the whole food chain. A food safety standard provides a method of preventing problems and crisis and it can also help to handle requirements from authorities, the market and others.

Dostoevskijs Anteckningar från Döda huset och Dantes Gudomliga komedi. Del I: Kronotop

Studies show that some pupils with ASD (autism spectrum disorder) can have difficulties in understanding written texts. The present study seeks to examine whether pupils with ASD differ in their reading comprehension of a factual text and a literary text. Another aim of the study is to obtain a picture of the reading habits of high school pupils with ASD, what reading strategies they use, and how they work with texts in Swedish lessons in school.The study uses texts from PISA surveys from 2009 and 2000. The factual text Varmluftsballongen (The Hot-air Balloon) was taken from the try-out for the 2009 survey and the literary text Gåvan (The Gift) was taken from the 2000 PISA survey. To gain some idea of the pupils? reading comprehension of the texts, the present study used the tasks accompanying the texts, with certain changes in the questions about the text on the hot-air balloon.
