Kriterier för inkludering var: ?randomized controlled Trial?, ?clinical controlled Trial?, ?clinical Trial? och ??humans.

The Yara N-Tester is a handheld chlorophyll meter which can be used in several different crops as an aid to determine if there is a need of complementary fertilization with nitrogen (N) or not. If the crop requires more N the N-Tester will recommend an amount in kg per ha. The possibility to assess the need of N depends on the strong relation that exists between chlorophyll- and N-concentration in the leaves of plants. In the multiannual Trial series ?Nitrogen to winter wheat at different soil conditions? measurements with the N-Tester was carried out at flag leaf emergence (GS 37). In this work the result of measurements, the NTesters ability to estimate the need of N in winter wheat, will be presented for the years 2008-2011.

Chinas government has a multifunctional program for a more sustainable forestry since 2000. This six key forest programs goal is to develop a more sustainable forest sector but also take environment consideration. The state forest administration in China has decided to create 5.8 million hectare of fast growing and high yield forest. Eucalyptus has showed to have good properties for pulp and timber production and therefore Eucalyptus plantations are under development in costal areas in southern China. By adding extra nutrients, growth can be enhanced in Eucalyptus plantations.

StoraEnso decided in year 2002 to build a pulp mill in the province of Guangxi, southernChina, and also establish eucalyptus plantations to provide it with raw material. By 2010StoraEnso controls about 90 000 of planned 120 000 ha, out of 75 000 ha is already plantedwith Eucalyptus.By using better genetic material, improve the tending, selecting the sites more careful and byusing a proper fertilization regime StoraEnso hopes to increase the mean annual incrementfrom today?s 25 m3/ha, on bark, to 35 m3/ha. This study is one part in this work to increase themean annual increment in the plantation.This master thesis is the forth in a series, that has followed up a fertilization Trial that startedin spring 2006 when the Trial was laid out and treatments decided. The aim with the Trial is toexamine the production potential of Eucalyptus urophylla in Guangxi, southern China.

Heat stress negatively influences the performance of dairy cattle such as lactation and reproduction. Heat stress can cause production losses as well as welfare problems. Years of research have shown that heat stress is a huge problem for dairy cattle in both the tropics and temperate zones but no such research have so far been done in northern European countries. It seems like shade is an important tool when improving pasture conditions and therefore deserves more attention. The aim with this study was to investigate whether there is a need of providing shade for grazing dairy cows during the summer in Sweden. Two groups of lactating Swedish Red dairy cows (n=15 per group) were kept on pasture.

In our case study we investigate how media chose to illuminate the process of court proceedings concerning a one specific rape case in Sweden during the spring and autumn 2007. For our study we have chosen to investigate two Swedish daily newspapers, one known to be a serious morning newspaper, Dagens Nyheter, and the other an evening tabloid newspaper Expressen. We would like to see whether the reports of the Trial diverge and if that is, how they differ.The rape took place in Stockholm?s posh area named Stureplan in March 2007. The two men 21 and 25 years old, accused for the crime were acquitted after the first instance.

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.

Nematodes are perhaps the most common animals in the world. Nematode populations can reach densities up to several millions per square meter in the soil. There are many factors which affect nematode communities in arable soil with respect to diversity and population size. Factors like tillage, crop, fertilization, nutrient status and moisture in the soil all have an impact on soil biology and in this way also have effects on the nematode community. This study is based on three different parts, soil samples taken in March 2012 and March 2013, soil samples taken monthly during the growth season of 2013 in bare fallow plots and a pot experiment.

Feed costs constitute a large part of the expenses of dairy farmers. Pasture is a high quality feed with a low cost. However, feeding with concentrates has been shown to enhance milk yield (Leaver, 1985; Bargo et al., 2003; Stockdale, 2004). The purpose with this study was to investigate how milk yield and milk composition were affected as the concentrate proportion in the diet decreased. Pasture behaviour was examined to see if the different concentrate levels affected the time cows spent grazing and ruminating.

Weaning is one of the most critical events in the piglet production with problems such as growth check and post-weaning diarrhea as a result. The lighter the piglets are when the growth check occurs, the harder they have to get back to normal growth rate. Creep feeding of piglets is used to reduce the problems by increasing the weaning weight and adapting the digestive tract to a starter diet. Hodge (1974) showed that the sow?s milk can not provide enough nutrients for maximal growth rate.

In 1972 the regulations on tax surcharge were introduced. In the new system the sur-charge are imposed by the Tax Authority (skatteverket) and not the Court. Since 1995 the European Convention on Human Rights constitute law in Sweden, which means that Sweden is forced to guarantee its citizens the human rights in the Convention. Article 6 in the Convention states that everyone, in the determination of his civil rights and obligations or of any criminal charge against him, is entitled to a fair hea-ring within reasonable time. The Article also expresses the right for anyone charged with a criminal offence to be presumed innocent until proved guilty according to law (the presumtion of innocence).

In May 1675, the local court in the northern Swedish parish of Nordingrå, which had approximately 1,000 inhabitants, held a preliminary investigation on 113 persons accused of witch-craft and superstition. For the majority of the 113, the main accusation was to have travelled to Blåkulla, a place where witches according to Swedish folklore participated in satanic festivities and rites led by the Devil himself. The preliminary investigation was held at the request of The Royal Witch-craft Commission. Nordingrå belonged to the province of Ångermanland, one of the Swedish provinces with the highest number of witch Trials in the 1670s. The Trials in Nordingrå have, more or less never been examined before, mainly due to the fact that no sentences or penalties were ever imposed.The purpose of this paper is to examine social relations and social conflicts in Nordingrå with the records from the witch Trial 1675 as the primary source.

What happens when historical theories are used as evidence in a Trial? Is it possible for historians to use their own scientific tools when acting as participants in a juridical process? And how do judges deal with historical evidence? The aim of this study is to answer these questions by analyzing a specific Trial, known as ?Härjedalsmålet?. Härjedalsmålet was a court case about the Sami people?s right to let their reindeer graze on private property grounds in Härjedalen during the winter season. Their claim to this right was based on prescription of time immemorial.

The choice of harvest date for leys is one of the most important factors affecting the size and quality of the harvest. An early harvest gives a high nutritive value while a late harvest gives larger quantity. Today?s aim to produce high nutritive leys gives early harvest dates both in primary growth and regrowth in northern part of Sweden. The consequence is a growth in the autumn, a "third harvest".The aim of this master thesis was to study the effects of different harvesting systems and their effect on size, feed quality, wintering and economy for conditions in the northern part of Sweden.

This study was based on measurements of growth and shape of 50 clones of wild cherry, Prunus avium L, in south Sweden and aimed at finding out wether or not any of these clones are useful for commercial propagation. Initially, a short assembly of documented knowledge concerning wild cherry as a timber producing tree species was put together. The study of the 50 clones includes information gathered during the fall of 2006 from four Trials located in the counties of Blekinge, Småland and Västergöland. The oldest Trial, founded in Tranemåla, Blekinge, in 1992, was focused on offspring and aimed at discerning differences between provenances and at developing an adapted plant material. The other experiments were both clone Trials and founded in 2002. These are based on 50 individuals selected from the offspring Trial in Tranemåla.
