Aktivitet som sjukdomsmarkör på kalvar i gruppsystem :
Since long, Sweden has had exceptionally low calf mortality compared to most
other countries. The tradition has been to keep calves in individual pens. With
increasing number of cows per herd there is now a larger interest in more efficient
and economical group systems for housing calves. However it has been noticed
that bigger herds have more health problems and higher calf mortality than
smaller herds. The early signs of disease are harder to detect when the animals are
not fed manually.
Skogsmaskiners bränsleförbrukning :
This report is a thesis work for a B.Sc. in Forestry exam at the School for Forest Engineers, SLU. The aim of the work was to compare fuel consumption during work in practical field conditions with a standardized method developed by Skogforsk (The Forestry Research Institute of Sweden), (Brunberg, 2005) for harvesters and forwarders from different manufacturers and of different sizes in order to promote the development of more fuel efficient machines.
Two studies were carried out.
- Statistics of fuel consumption were collected.
- An inquiry was sent out in order to get more detailed information of different aspects influencing the fuel consumption.
The studied machines were divided into two classes, large machines (> 150 kW), and average size machines (100 ? 150 kW), and of the manufacturer Timberjack and Valmet.
Our results shows a 15 % lower fuel consumption for average size harvesters and an 8 % higher fuel consumption for large harvesters compared with Skogforsks model.
Effekten av total mängd dietärt fett på lipidprofilen : En litteraturstudie
The effect of total dietary fat on the blood lipid profile: a reviewFat consumption has increased in Sweden in the 21th century, probably due to the advancement of the diet low car high fat (LCHF). Also, cardiovascular disease is the leading cause of premature death in Sweden. Various blood lipids are used to evaluate the cardiovascular disease risk; total cholesterol, LDL, HDL and triglycerides among others. High levels of total cholesterol, LDL, triglycerides and low levels of HDL are believed to increase the risk. The purpose of this review was to examine the effects of high-fat-diet on blood lipids, cholesterol, LDL, HDL the ratio between LDL/HDL and triglycerides through a systematic review.
En grupp ungdomar i tvångsvård: bakgrund, begåvning och självbild
The aim of this study is to describe a group of youths in compulsory care at a SiS institution in the south of Sweden. The study focuses on intelligence (measured with WISC-III) and self-report, i. e. what the youths think of themselves (measured with Jag tycker jag är). Attempts were made to see if background factors (based on information from the standardized ADAD-interview) seem to be coherent with intelligence and/or self-report and if so, what those background factors are.
Styrketräning för truppgymnaster : mer än bara kroppsvikt som belastning?
Syfte och frågeställning: Syftet med denna studie är att undersöka de eventuella fördelar styrketräning med yttre belastning kan ge kvinnliga truppgymnaster på juniornivå. Frågeställningar: Vilken effekt på explosivitet i nedre extremitet har sex veckors powerträning med yttre belastning på truppgymnaster? Skiljer resultaten sig från de som uppnås vid traditionell gymnastisk styrketräning?Metod: Två lag som representerar Sverige-eliten på damsidan i juniorklassen delades in i test- (n=7) och kontrollgrupp (n=8). Testgruppen genomförde under sex veckor ett specialdesignat träningsprogram riktat mot power medan kontrollgruppen genomförde traditionell gymnastisk styrketräning. För- och eftertester genomfördes för att utvärdera effekterna av programmen.
Noggrannhet vid låghöjdsfotografering från obemannad heliumzeppelinare
The development in photogrammetry has created possibilities for new methods in aerial images acquisition. Remotely-controlled imaging from an unmanned helium zeppelin is a new and relatively unexplored acquisition. The purpose with this degree project is to evaluate the accuracy of this kind of low-height photographing system, a task given from the consultant company WSP, in Sweden. Landbadet in Uddevalla municipality was chosen as a test field for the zeppelin. Seventeen images distributed over three strips were acquired from the flying height of 80 m.
Kapitalstrukturens inverkan på företagsvärdet : - En kvantitativ studie av den svenska aktiemarknaden
Background: During extreme market conditions like the period during fall 2008 the discussion of what affects company value becomes apparent. The capital structure is the relation between borrowed capital and equity in a company´s financing mix. What impact changes in capital structure have on company value is a widely debated subject within the theory of finance. If a relationship between capital structure and company value exists the implication is that an optimal capital structure where company value is maximized also exists.Aim: The aim of the thesis is to study whether a certain relationship between capital structure and company value exists among selected stocks and companies listed on Stockholmsbörsens OMXS30.Implementation: With aim to fulfill the purpose of the thesis regression analysis has been performed among chosen stocks and companies. The empirical results eventuating from this have been analyzed from the view of elected relevant theory.Completion and results: We find that during normal market conditions a positive relationship between debt ratio and enterprise value (EV) can be established.
Metoder för lastprioritering i fjärrvärmecentraler
A problem in the field of district heating is the oil burners needed to provide power when a peak load occurs. One possible way of reducing the needed amount of oil is to reduce the power demand for space heating in the district-heating substations when the need for district heating water exceeds a certain limit. This can be done by use of a locally working controller function.In this Thesis the options concerning load priority are evaluated. To evaluate the potential for using controller functions concerning peak load priority an experiment was brought out in a chosen district-heating substation. The impact on the indoor thermal comfort during a heat reduction was also taken into account.
Yeast in forage crops and silage aerobic stability at 15 Swedish dairy farms
This study investigates the role of yeast in green crop and its impact on the aerobic stability of silage. Fresh crop was collected from 15 farms in southern and middle parts of Sweden during the summer 2014; samples from the primary harvest was collected from eight farms and samples from the first regrowth harvest was collected from seven farms. The grass was ensiled in 1.7 l glass silos. After three months of ensiling, silos were opened and silages were stored aerobically for 10 days. Samples from both harvests were ensiled in completely airtight silos, but samples from the second harvest were also ensiled in slightly ventilated silos.
Chemical analyses and yeast counts were performed for fresh crop and silage.
Etik för revisorer : Den etiska resonemangsförmågan hos studenter
In recent years the interest for ethics has increased exponentially. It has become more and more common with the ethic rules and guiding of principles within the business world, both in companies and in different professional groups. Auditors face difficulties and have to deal with different ethical problems where ethics and morality is taken up. It is important that accountants can react in a legal and correct manner. To become an accountant a person should have gone through college or university where the schools have some responsibility to provide the student with basic ethics course for a accounting education.The main aim with our paper is based on the theories of Lawrence Kohlberg about ethical development investigation potential differences in the ethical reasoning among student who are in first or last year of the studies with orientation in accounting.
Likabehandlingsprincipen i uthyrningslagen - om lön för arbetare inom bemanningsbranschen
In Sweden has the temporary agency work industry settled in an explosive way since the deregulation of the unemployment agency monopole in 1993. The demand of civil right for the employer that is rented out confronts the entire labour law regulation with new challenges.The purpose with this paper is an investigation of the principle of equal treatment in The Swedish temporary agency work act and also to create a deeper understanding of the effects of labour and employment relationship. An investigation of relevant collective agreements will be done to highlight the difficulties the principal of equal treatment is exposed to. Further on is there a will to gain understanding for the wage concept and what possible can be included in the wage concept in relation to the principal of equal treatment in The temporary agency work directive. By using the dogmatic method, an approach to descriptive identifying relevant sources of law and clarify the legal situation in the area.In the conclusions it will be determined that the principle of equal treatment in The Swedish temporary agency work act have different effects depending on if the temporary agency or if the client corporation is tied to an collective agreement alternative if a collective agreement is completely missing.
Kan 4 veckors beta-alaninsupplementering öka prestationen hos idrottare inom högintensiva sporter i jämförelse med placebo? : Examensarbete inom biomedicininriktning fysisk träning 180 hp
I dagsläget finns det en hel del kosttillskott som lovar bättre prestation, men många av substraten har inte tillräckligt med forskning bakom dem som bevisar att de verkligen fungerar. Tre av de kosttillskotten där det finns mycket forskning på och har visat sig förbättra prestationen är kreatin, koffein och natriumbikarbonat. Nyare forskning har studerat supplementering av beta-alanin som tros kan fördröja muskeltröttheten under fysisk aktivitet. Det är inte mycket av denna forskning gjord på överkroppen hos elitidrottare, därför ska detta undersökas i denna studie. Många teorier om muskeltrötthet involverar att vätejoner (H+) som härrör från bl.a.
Utvärdering av klusteranalytiska metoder i kombination med bibliografisk koppling: en bibliometrisk kartläggning av aktuella forskningsteman inom informationsvetenskap
The purpose of this thesis is to evaluate the combination of bibliographic coupling and three hierarchical cluster analytic techniques: average, complete and single linkage. Bibliographic coupling is applied as a measure of similarity between recently published articles and the cluster techniques are used for the partition of a set of articles into subsets of articles with similar research focus. The field of information science is applied as the test arena and the selection of data, i.e., the article population to be partitioned, is based on a number of central journals. Methods of evaluation include both quantitative approaches as well as a qualitative one. For comparing the resulting partitions, adjusted Rand index is utilized and for the establishment of cluster coherence and isolation, measures of average normalized coupling strength is applied.
Hur skall skogen skötas? ? en analys av skogsfastigheten Fagerdal 2:10 i Jämtland
The forest property Fagerdal 2:10 was donated to the Swedish University of Agriculture in 1995 by Erik Rönnberg. The dominating species is Norwegian spruce (Picea Abies) and the average age is high due to selective cutting. The aim of this study has been to analyze how the forest on the property should be managed and demonstrate how a better estimated forest data affects the future management. The impact of the management on the carbon stock of the property was also examined.
A forestry plan established in 2009 by Skogssällskapet was used as a basis for the analyses.
