Compared with a few years ago, the cost of concentrates has increased substantially and because of that an increased proportion of pasture is of interest. Pasture is cheap and the farmer does not have to harvest when the cows do it themselves by grazing. This saves both money and time. According to research milk yield decrease with an increasing proportion of pasture in the diet. This is because cows on pasture will have lower dry matter intake than cows with supplements.

Eutrophication is an environmental problem that affects more than ten percent of Swedish lakes. Excess nutrients increase the growth of algae, and cause major problems in the ecosystem through oxygen-free bottoms, fish kills, and at worst dead bottoms. Agriculture accounts for 44% of human emissions of phosphorus to lakes and rivers. Leaching occurs of particle bound phosphorus and of dissolved phosphate. The amount of phosphate in the soil solution that may be leached is partly due to the prevailing pH in the soil solution. The purpose of this study was to investigate how the relationship between phosphate solubility and pH was affected by liming.

On December 1th 2009 the Lisbon Treaty entered into force, and through Article 13, the recognition of animals as sentient being was given a more visible part in the very core of EU law. This was an effect of a political decision to commit to the issue, partly because of the will to further harmonize the EU market, but also due to increased societal concern for the wellbeing of animals. Over the last decades, ethical awareness is growing in many countries, one reason being new scientific discovery. This influences legislators and policy makers to take proper action, and in this way, ethics and science often work together as the very basis for the development of new legislation and policies. There is yet to be seen what the actual consequences of Article 13 will be, since the legal obligation remains the same and there are still some reservations in it.

The competition in the milk industry has increased during the last couple of years. This is a result of the trade barrier that dissolved when Sweden entered the European Union. The membership signifies an increased internationalization for the dairies, which has also increased the existence of low price chains in the Swedish food market. The increased share of private brands has strengthened the competitive situation for the manufacturer- owned brands. Three of Sweden?s seven largest dairies have now decided to launch a low price milk to cope with the competitive situation.

The purpose of this essay is to find an answer to whether the methodology used by the Naturskolan conduces to learning and also if the Naturskolan, as a method of its own, leads to an increased interest in natural science for the pupils participating in the classes at the Naturskolan.The method which has been used to reach the results of the study is a quantitative opinion poll. The results reached through the study has been compared to previous research in the subject. Deeper studies were made to examine however the interest of the pupils was influenced by their visit at the Naturskolan.The results of the study show an increase of interest in natural science after visiting the Naturskolan. It also shows that the teachers? interest in natural science and outdoor pedagogy has increased by the visit at the Naturskolan.Through this study we came to the conclusion that the Naturskolan is a good method to learning..

Beans are a global source of plant-based protein, and in some countries, they constitute a primary source of protein intake. With ongoing climate change, including rising temperatures, it is necessary to adapt beans to ensure a reliable food supply. An important mechanism that many plants have, to cope with high temperatures, is cooling through transpiration. During transpiration, stomata open and release water vapor. Water molecules use heat energy from the leaf to convert into gas, thereby cooling the leaf.

The aim of this study is to investigate how multiple tree handling harvesters perform compared to earlier developed standards. The study shows that multiple tree handling harvesters are more efficient in thinnings stands with mean stock volumes less than 0,12 m3fub per stock. The increased efficiency is different for different mean stem classes. In stands with a mean stem volume of 0,04 m3fub per stock, the increase can be as high as 40 percent while it is about 10 percent in stands with a mean stem volume of 0,12 m3fub. Comparisons have been done between stands that are felled with partly limbed stands and stands without partly limbed assortments. The difference in performance is clear and shows that the partly limbed assortments strengthen the multiple tree handling harvesters positive effects in low dimension thinnings.

This thesis aims to show the positive effects of marketing by studying whether the regulation on direct marketing to consumers of prescription drugs today prevents to consumers accurate information and better health, and how consumers relate to the possible legalization of increased marketing through controlled and information audited webpages. Methods used in this research are qualitative method, quantitative method, documents and websites studies. The thesis fulfills the purpose as it shows the potential positive effects of an expanded marketing through pre-approved websites. It also shows a demand from the consumers' side and a need for increased awareness for more empowerment over their own health.

AbstractTitle: See each other on the Internet or on a café? A survey about social consequences of Internet usage. (Umgås på Internet eller på ett café? ? en studie om Internetanvändningens sociala konsekvenser.)Number of pages: 34 (including enclosures).Author: Carolin Johansson.Tutor: Else Nygren.Course: Media and Communication Studies C.Period: Fall 2007.University: Division of Media and Communication, Department of Information Science, Uppsala University.Purpose/Aim: The purpose is to get increased knowledge about the social consequences that may come up when young people at the age of 16-20 are using the Internet.Material/Method: The material consists of a questionnaire that I made with questions about Internet usage that 84 young people from five classes (from three different upper secondary schools) answered.Main results: To have access to a computer and Internet and the fact that broadband is more inexpensive now than before leads to an increased usage of the Internet. I found out that chatting, music/movies, searching for information and using the Internet for entertainment is what most of the participants spent the most time on while using the Internet.

Recent years there has been discussed how the critical situation in the housing market threatens the Stockholm region's growth. The thesis objective is to examine whether there is a scientific link between the lack of housing supply and growth. The thesis also intends to identify solutions for increased housing construction, for instance by examining the conditions for a greater regional perspective and influence on the region's housing supply. The thesis empirical study is based on semi-structured interviews with representatives from the Government, municipalities and the housing industry.In Sweden, research on the relationship between housing shortages and growth has not been conducted to that extent it can be said to exist scientific evidence regarding the growth threat. However, in Britain and the U.S, empirical studies show that a lack of housing supply has hindered growth through negative impact on countries' gross domestic product.

Östby waterworks in the community of Kramfors has since 2003 had problems of fast clogging of the slow sand filters. As the clogging appears more often, they must be cleaned more frequently which has made the drinking water preparation difficult. Wintertime it has sometimes been impossible to clean the filters which has led to their closing and this has influenced the water quality negatively.The waterworks is a surface waterworks which takes its raw water from the lake Sjöbysjön. The water is flocculated and filtered in a contact filter with the flocculent EKOFLOCK 91. Thereafter it is alkalinized before it reaches the outdoors placed slow sand filters.

The objective of this study was to examine how an IT department has been affected by the changes of increased local usage of IT, and how the usage have affected municipalities IT departments demands of IT support. In the study we explore how both the IT department and the IT support works by interviewing present and former employees at the local IT department. The current IT department have undergone a series of local changes over the last 20 years, the department has gone from only having internal users to getting the entire municipalitiy?s agencies of IT as users. It started with how the municipality began to dig down fiber optic cable in the middle of the 1990?s, and today has started to develop solutions as to how to meet the demands of future usage of IT.

The number of parties in the Swedish parliament has increased from five to eight during the last twenty years. The political agenda is still based on a two-block system with the consequences that the number of parties in each block has increased. To be represented in the parliament, a party needs at least four per cent of the total votes in the election. If only one party fails to achieve that, the whole block will lose the election to the other block. This could encourage voters to vote tactically for the small parties in the block to ensure that the block wins the election.

The question of direct citizen participation in politics and administration is a contestable one. Its proponents claim that it has positive consequences even for the more "traditional", representative democracy, since participation leads to an increased political knowledge and increased political interest, and thus creates a revitalised democracy. Critical voices have however been raised to the validity of this claim. Critics have also pointed out direct participation as problematic, because it leads to problems of political inequality: a difference of political influence between ? on the one hand, the citizens participating directly and those that restrict their political participation to voting, and ? on the one the other hand ? between the institutions, for example schools, that employ, and don?t employ this method of direct citizen influence.In this essay, these two points of criticisms are tested in the context of user-boards in elementary and secondary schools.
