Spårelement i Sveriges jordbruksmark : flöden, trender och fältbalanser

Field balances based on supply and removal of trace elements from the topsoil have been calculatedfor farms specialized in crop, dairy and pig production in Sweden. Today's field balances have beencompared with the field balances of 1990 in order to examine if, and then how, the situation haschanged. Studied trace elements are arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu),mercury (Hg), manganese (Mn), nickel (Ni), lead (Pb) and zinc (Zn).The balance calculations show that the stores of Cu and Zn are depleted with an average rate of -15% and -6 % over a 100-years period on crop farms when only commercial fertilizers are being used.The concentrations of Hg and Pb tend to increase in the topsoil on crop farms with more than 3 % forHg and with 2 % for Pb in 100 years. There is today balance between supply and removal of the traceelements As, Cd, Cr, Mn and Ni. In the south of Sweden, on crop farms with sugar beets in the croprotation, one can see a decrease in the concentration of Cd in the top soil by -6 % over a period of100 years.

Marktäckande, lågväxt vegetation på ställverksmark : en biologisk bekämpningsmetod mot ogräs

Unwanted vegetation on the land of electric transforming stations is a problem, in the sense that it contributes to higher fire risks and also constitutes an obstacle for people performing maintenance operations at the station. Such unwanted vegetation is controlled using herbicides and mechanical measures. Since the use of herbicides implies environmental hazards, there is a need to find alternative ways of fighting the unwanted vegetation. Investigation into suitable plants for ground cover, trials in the greenhouse, trials in the field, soil analyses and compilation of experiences from similar trials are parts of this work. The paper also contains analyses of possible environmental benefits and economical gains. There is also a final discussion of some proposals regarding alternative weed controlling methods.

Framtagning av en remdriven växellåda till en häcksax

The project was performed in collaboration with Husqvarna, one of the world?s leading manufacturer in the market of electric outdoor products.

Mansklubben inom företagsekonomisk utbildning - En fallstudie om varför så få kvinnor fördjupar sig inom finans

Gender balance within the business administration field at university level is an area that has gained increased attention in the last decade. As gender balance contributes positively to the scientific and educational achievements within all disciplines, many studies have tried to understand the decision-making processes of students when selecting a business specialisation. However, little attention has been devoted to the finance discipline although there is a remaining gender imbalance within the field at higher-level economic studies. This thesis was performed as a qualitative case study and is based on interviews with second-year bachelor students facing their choice of specialisation at the Stockholm School of Economics. Through an application of the Theory of Reasoned Action (TRA), this study aims to examine factors that influence female business students' intentions to choose a specialisation.

Strängluftning av vallfoder : Inverkan på ensilagets torkningförlopp, spill och smörsyratillväxt

When harvesting ley you hope to get a fast drying and a faster harvest. If there is a system with round bales, you need to have a dry matter close to 45 %.

There are few tests to prove the efficiency of this machine.

Friidrottsungdomars fysiska kapacitet över tid : En retrospektiv studie av intagningstesterna vid friidrottsgymnasiet i Växjö mellan åren 1982 ? 2009

Background: Today when leisure time is spent, spontaneous sports activities decrease, due to a more comfortable way of living and physical capacity among non active adolescents decreases. There for it´s interesting to see how the physical capacity level has changed over time among young people participating in organized leisure time sports.Studies around the world show that young people standing outside organized sport activities have tended to decrease their physical activity levels over the last few decades. Less leisure time is spent doing physical activity and sometimes gets put into context with increased time spent behind the computer or inactivity.Design: A retrospective study of the test results on physical capacity between 1982 and 2009 for students applying to Växjö track and field high school. A total of 635 students (15 years old) have done 11 physical tests during the years. Five of these tests, with enough participants (at least 100) and documentation over at least 10 years, were used in this study.Results: This study shows that young track and field athletes have maintained the same physical capacity from 1982 to 2009.

Utvärdering av Politiskt Bistånd : En fallstudie av ett politiskt biståndsprojekt i Laos

The findings in this case study are mainly based on material collected during a field trip with a fellow student to Laos in February-March 2005, which was sponsored by Sida through a Minor Field Study scholarship. The original interest was to study a political aid project (Governance and Administrative Reform Project Luang Prabang, GPAR LP) in a country like Laos with very complex preconditions such as one-party polity. In Laos my interest in evaluation of political aid grew mainly because I found out that the two donors in the project, Sida and the UNDP, had reached different conclusions in their respective evaluations of the project.The main interest in this thesis has been to study how donors have evaluated a political aid project. The study shows that Sida and UNDP used, what in the literature usually is referred to as, Conventional evaluation as methodology when they conducted their evaluations of GPAR LP. The study also shows that the main reason for the different points of view that are expressed in the evaluations depend on a lack of dialogue and consensus, regarding for the project crucial concepts, rather than choice of evaluation methodology.

Nästa generations syn på skogsägandet och skogsägarrörelsen : en enkätundersökning bland vuxna barn till dagens medlemmar i Norra Skogsägarna

The future of the forest owners? associations are intimately coupled to the development in family forestry. Forecasts have been made that predicts that the number of forest properties for sale on the open market will increase as the interest among the children of the property owners is considered to decrease. The associations are also affected by continuing individualism in the society which may affect attitudes to as well as interest in membership. The objective of this study was to study the attitudes among grown-up children of members in a forest owners association towards overtaking the forest property as well as membership in a forest owners association.

Designriktlinjer för övervakningssystem

Design principles are usually used by interaction designers to help creating a user friendly design by making the designer think about the different aspects of the design. These design principles has been further developed since they emerged in the 1990s, and today they're often used in the field of interaction design. By using the design principles, bad design can be avoided and the frustration of the user reduced. Design patterns is described as structural and behavioral characteristics to improve the environment in user interface amongst other areas. These characteristics could make things easier to understand or improve their appearance, they make tools more usable.The purpose with this essay is to identify design guidelinesto be used by developers when designing surveillance systems.

Rekryteringsprocessen och sociala medier : Hur arbetar olika HR-funktioner i Sverige med sociala medier i rekryteringsprocessen

An increased use of social media has enabled a new arena for HR functions and the work with HR issues. Proponents are critical of this, as it can lead to ethical and legal dilemmas. So far the research on this area is limited. On this basis I found it interesting to study how social media is used in connection with the recruitment process. Those who will benefit from this study are primarily those dealing with recruitment, but also others working with HR issues.

???????????? ???? ??som?leder oss i triumf??   En exegetisk studie gällande vad Paulus avser för betydelse och funktion med sin metafor i 2 Korintierbrevet 2:14a.

AbstractIn this essay I examine the exegetical problems concerning the interpretation of the metaphor ???????????????? in 2 Corinthians 2:14.The regular idea of the metaphor is that the apostle Paul is using the picture of a Roman triumph to describe the apostle?s and his co-worker?s service for God. This includes that God is leading them into many sufferings finished off with a martyr death as the triumph was very painful for its prisoners and mostly ended with an execution. But since A.D 300 such an interpretation has been questioned. Scholars react primarily to the cruelty of it and ask if that really was Paul?s meaning.

Den ok?nda e(s)tniska sidan av svensk litteraturhistoria. Om den exilestniska litteraturen i Sverige

At the dusk of the Second World War, when the Red Army was approaching Tallinn and the second Soviet occupation of Estonia could be foreseen, almost a tenth of the population left the Estonian coasts to seek refuge in the West. About 30 000 of those ended up in Sweden, among which were some of the most prominent Estonian novelists and poets. Sweden would become the literary center for the worldwide exile Estonian diaspora. However, the fact that a few dozens of Estonian authors published some 2 000 titles in Sweden, where most of the authors as well as the main publishing houses resided, was and has remained unknown to most Swedes as it has gone fairly unnoticed to the field of Swedish Literary Studies. From the perspective that the exile Estonian literature written in Sweden is actually part of our history of literature, this thesis aims to find out what factors have had impact, and how, on the authors? opportunities to gain recognition by the Swedish literary establishment and eventually being included in the Swedish literary historical works.

Samband på individnivå mellan akuta klövskador och cellhalten i mjölk hos mjölkkor :

The purpose of the present study was to investigate the cow-level association between acute hoof lesions and the somatic milk cell count in dairy cattle. Cows from three loose-housed Swedish dairy herds were enrolled in the study if they had an acute hoof lesion treated by a veterinarian or professional hoof trimmer during the preceding year, according to farmer records. Studied lesions were sole ulcer, dermatitis, interdigital necrobacillosis and hoof abscess, in each case causing lameness. For each hoof-diseased cow, 0 to 3 healthy cows were included, matched with respect to herd, breed, parity and lactation stage. Cell counts were obtained from monthly test recordings from one month before to three months after the hoof-lesion diagnosis, and log-transformed.
