Today, our cows experience a harder pressure to achieve higher milk yield. To manage this challenge the animal needs first class feeding and treatment. An important aspect of the feeding is to fulfil the need from the cows of especially fiber; and fiber with a sufficient proportion of long particles. Both too much and too little fiber is bad for the wellbeing of the cow, and she might get diseases like acidosis. Many models for feed management have been developed to secure that the animal gets enough of e.g. fiber with a sufficient proportion of long particles.

Skärgårdsstiftelsen, which is responsible for several of the archipelago islands in Stockholm, has chosen to explore the possibilities for more sustainable heating systems in buildings on the islands in collaboration with KTH. A reduction of energy use and improving the efficiency of existing heating systems are included as part of the environmental work. This report studies the island of Grinda, which is located outside the area of Vaxholm in Stockholm. The study area consists of a guesthouse consisting of a restaurant as well as conference facilities and four neighboring cottages used for overnighting. The cottages now run solely on direct electricity, both for heating and hot water.

Climate and environmental issues is now high on the agenda. We live in a generation that must try to solve some major environmental problems. Buildings and habitations account for approximately 40 % of Sweden's total energy today. To reduce this figure, as needed, more research in the field of energy efficiency is required.This thesis concerns the heating of buildings. The load on district heating is heavy during certain times of the day.

Gröna byggnader har under senare tid blivit ett alltmer aktuellt begrepp eftersom den globala uppvärmningen uppmärksammats och miljöfrågor har uppkommit i fler sammanhang för att reducera utsläppen. Mycket forskning inom området gröna byggnader hanterar till stor del kommersiella fastigheter, såsom lokaler och kontor. Studier har främst utförts i USA och Storbritannien. Nuvarande regering har som mål att uppföra 250 000 nya bostäder inom sex år. Detta väckte vår uppmärksamhet och uppsatsens syfte är att undersöka vilka incitament privata fastighetsägare har för att uppföra gröna bostadsbyggnader med upplåtelsen hyresrätt samt om nuvarande regler inom det svenska hyressättningssystemet påverkar dessa fastighetsägare.

The consumption and energy use in today's society contributes to the on-going climate change that creates a debt of life quality for future generations (www, DN, 2007, a). The resources that are used by humans exceed by far what is sustainable (www, Regeringen, 2007, a). The purpose of this paper is to examine how a message about energy conservation should be designed to reach youths. This will be attempted by showing their thoughts on energy and environmental issues and also what it would take for them to get more involved in these issues. The views of the youths are gained by a number of focus group-interviews, which where carried out in the fall of 2007, with kids in the ages 12 to 19. Apart from these interviews, interviews where also conducted with representatives from different youth organisations in Sweden, which gave their views on how to get a message across to kids.

The objective of this study is to investigate a new pedagogical material called 4DFrame, how it is experienced by informants and how suitable it is in education - in particular mathematics. Socioculturalperspective has a central role in this study when students are given opportunities for linguistic and social interaction during the experiment with the new pedagogical material. The methodology for this study has been visits, interviews, and observations. The study reveals that there are different views on the didactic potential for mathematics of the new teaching material, though no conclusions can be drawn regarding whether this material is more or less suitable in teaching since no research have been found that compares this with other pedagogical materials. Both national and international studies show the need to find alternative and better ways to make mathematic education meaningful.

Most of the clothes sold in Europe today are produced in developing countries where the production costs are lower. The exploitation of the developing countries has led to that the inferior working conditions in these countries have attracted attention from media and NGOs. Globalisation makes company activities more transparent and the absence of transnational laws calls for alternative regulations. Many companies in Europe has since mid 1990s developed codes of conduct to satisfy the demands of external and internal stakeholders. EU also brought Corporate Social Responsibility to it?s agenda in the beginning of the 2000s and subsequently signals of approaching laws were given.

Disinfection methods for drinking-water produced at the two water works of Stockholm Water Co are compared in this study. Three different nethods are compared; disinfection with chlorine gas, disinfection with sodium hypochlorite and disinfection with UV-light and monochloramine. The method used is Life cycle assessment, LCA. LCA is defined as the compilation and evaluation of the inputs, outputs and potential environmental impact of a product system shroughout its life cycle. The environmental burden is compared for the three different disinfection methods.

The prevailing food and energy crisis of the world, due to the declining reserves of fossil energy and a never ending rise of consumption, forces us to look into new fields to supply our energy demand. The boom of bio energy is criticized, as food crops are used to provide biodiesel and ethanol and the volumes are ridiculously small to supply world demand. Algae are one of the world?s oldest life forms and exist in many different phyla, providing a great variety to choose from, for different purposes. Cultivating microalgae offer a way to produce energy at great volumes without competing with food production and at the same time the algae offer a way to use our expensive nutrients in a more efficient way, besides this the algae are carbon dioxide neutral since their carbon source can be supplied by the atmosphere and the additional energy required can be supplied by algal oil or other renewable sources.

Fukthantering är idag, trots god kunskap inom ämnet, ett stort problem inom byggproduktion då tunga betongstommar ska torkas ut under pressade tidsplaner. Det finns en uppsjö av beräkningsmetoder och hjälpmedel, exempelvis ByggaF och Torka S. Däremot finns inget enkelt sätt att kombinera uttorkning, energiåtgång och kostnader som är användbart i produktionen.Miljön är kanske ett av det här århundradets största samhällsproblem. Lokala brister kan få globala konsekvenser och för att bygga ett hållbart samhälle måste detaljnivån studeras. Byggbranschen är en stor energibrukare där stor vikt på energibesparingar läggs i förvaltningsskedet, medan det försummas i produktionsskedet.

As emission legislations across the world continuously pushes engine development forward,engineers constantly need to come up with and implement fuel saving technologies. During thelast decade, variable cam phasing has become a popular solution to increase gas exchangeefficiency. This configuration is typically mechanically constrained by camshaft limitations, anda solution to circumvent this problem would be to use a different valve actuation principle.One example of this is to use pressurized air controlled by electrical solenoids. Such a systemhas been developed byCargine Engineering and this provides the starting point for this work. Tobe able to operate the valvetrain on an actual engine, a control system is needed.

Over the past one hundred years, there has been an increasing globalization and industrialization of the food systems. As a result, the distance between the production and the consumption of food has increased, both in time and space and in the minds of people. There is also an increasing concern for the environmental effects of industrial farming and the long distance transportation of food. Sustainable agriculture and efforts to build more sustainable food systems has emerged in opposition to the global food market. The definitions of sustainability usually include environmental, social and economical aspects. To build more localized food systems is seen as one way towards increased sustainability.

More and more companies open up facilities and stores in countries all around the world. Entering a new country means a new culture, a new language, different norms and values and new people with a different way of thinking unlike what you are used to. In order to survive and be successful in this new country means that you have to adapt to the new culture and its components you encounter.The purpose of this thesis has been to identify possibilities and barriers in the Middle Eastern culture affecting international clothing companies. Furthermore it has been investigated how these companies must adapt their products and promotion to this culture.In order to obtain relevant data for achieving the purpose of the study interviews and observations was made at three international clothing companies in Tehran, Iran. These were Mango, United Colors of Benetton and adidas.
