Milk yield levels in dairy cows are influenced by many factors such as nutrition, breed, health status, management and environment. This study was conducted among small scale farmers in Zambia, where the climate can be dry for up to six months per year and cause a lack of green pasture for livestock and on-farm produced feed. The purpose of this study was to identify management factors that can influence milk yield at small scale dairy farms in Zambia, and present advice that could improve productivity, without the need of expensive investments. The study included semi-structured questionnaires presented to the farmers (n=29) including questions about cattle management and milk production. Testing of somatic cell count (SCC) with DCC (DeLaval Cell Counter) from herd milk samples (n=56) and observation of housing and animal body condition on-farm was also made.

The main environmental problem for aviation is the great amount of exhaust gases, mainly nitrogen oxides, carbon monoxide, carbon dioxide and hydrocarbons - mostly "greenhouse gases" leading to climate changes. I decided to sort out what is being done to decrease these problems and what regulations there are concerning air pollution by the means of searching the internet and using publications from aviation authorities for current figures. I chose to scrutinize authorities on political, authority and company level, resulting in summarizing the work of UN and EU respectively, ICAO (International Civil Aviation Organization), JAA (Joint Aviation Authorities) and LFV (Swedish Civil Aviation Authority), and finally SAS, representing the airline companies. Conclusion that I have drawn are thatthere are regulations for air pollution, written down in ICAO's Annex 16, that are to be followed. Secondly, LFV are environmentally controlling their nineteen airports and since economy is an important reason for not giving priority to environmental issues in aviation emission charge and noise charge are added to the landing fees.

Environmental impact and management of energy is a highly topical issue in today's society. Climate impact must be reduced. The Government has set a target to reduce energy consumption in buildings by 20 % by 2020 and 50 % by 2050 compared to the energy use in 1995.With this in mind, we chose to examine how property owners can work on improving energy efficiency in existing apartment buildings. We also wanted to investigate profitability of different increasing energy efficiency measures and the calculation methods and the risk assessment performed by such investments. To tie in with government objectives, we also saw the possibilities of achieving these goals.20 companies were interviewed, of which 14 were property owners and 6 were consulting firms that works with energy efficiency.

Environmental issues and ecology is something that is discussed by the Climate board of the UN and by our Swedish politicians. The first part of the thesis deals with the effects of emissions of greenhouse gases in our atmosphere. There is a discussion about what counts as greenhouse gas. Interviews have been made with two growers of annual plants and one interview with a person who has worked hard to increase the use of perennials in his work place, Mjösund?s cemetery.

In this essay I have summarized important factors for an effective, but also successful, way to raise and house heifers. This study can be used for other dairy farms to use as guidelines in their process to raise heifers. To let outside heifer growers house, feed and have the heifers pregnant before return, can save a lot of work. But also moneywise, when the care and individual programs makes them strong and increases the growth.The result is a faster breeding and an earlier time for their first calving.In Sweden the heifers tend to be older if you compare with Denmark or United States where the custom heifer raising is well known and growing. One reason can be the Swedish laws regarding outside grassing for all cows during the summer months.

Risk-based sampling program of microorganisms in the water source in northern SwedenAfter several disease outbreaks caused by parasites in the drinking water during the last years, it is more essential than ever to insure that the water supply companies have enough barriers to counteract the presence of microorganisms in the outgoing water. It is also discussed whether climate changes such as increased precipitation can have a connection to the increased cases of parasites in water sources. The water source at Gäddvik is Luleå municipality?s largest and provides drinking water to 64 500 of Luleå?s 74 000 inhabitants. The investigation of microorganisms in the water source, especially in the Lule River has not been as prioritized as the sampling of chemical parameters.

Background: Last year (2006) has been a year when the environmental issues figured more often in the media, and the environmental awareness among common people increased. Environmental climate reports have lately been on the headline all over the world. As a result of the increasing population in the world, it?s becoming more important to be aware of the environment. To do that, it is important to maximize the efficiency in the work with the environment.

In this thesis tests has been performed on the pull strength of screws glued into glulam beams.The experiment is based on the already approved method whereby the diameter of the drilled holes is the same as the screw outer diameter of 1 mm or bigger. The screws strength class shall not be less than 4.6 (EN ISO 898-1:1999, 1999).The difference in the experiments that were performed where that the drilled diameter were 1 mm smaller than the outer diameter of the screw so that the screw thread was worked into the wood.In the tests the gluing where made on M8 glulam beams. The screws where drilled at and angel of 90°tangental to the fiber direction with a diameter of 7 mm. The gluing of the screws where made in three different depths and where later exposed to pulling forces. The results showed both pulling breaks and screw breaks when they reached their maximum capacity.

In the government's bill on infrastructure for 2010-2021, the government presents that road investments should be prioritized before investments in the railway. The grants for operation and maintenance of the railways are much higher then in the last government's bill. Furthermore the current founding of investment in railways is higher then for road investment which is in opposite of the bill on infrastructure's directives. Therefore the purpose with my thesis is to find which factors that can explain how come the government has chosen to take these actions. As a model to help me achieve my purpose I have been using a modified version of the DBO-theory, where the basic factors to explain an action is Desire, Belief and Opportunities.

To plan and build a garden in Dubai has other conditions and challenges than what you experience in Sweden. The heat, wind and lack of water makes the need for durable plants, a good design and landscaping important if you want to have the opportunity to use your garden during most of the year. The soil is poor of nutrients, alkaline and sometimes saline, witch makes supplying the soil with organic material and various fertilizers necessary if you want to be able to plant a bigger range of plant material in your garden. Another important part is to provide your garden with a good irrigation system that should be put into the ground before planting so that the plants are given a more even irrigation. It?s relatively green scenery you meet and to me it?s in a way surprising since the country with its climate is rather harsh for the purpose of supporting plant life.

The use of energy is an important question in today´s society, and a substantial part of the energy that is used today is used in our homes. To lower this usage is vital, and there are regulations in place both on the national and the local level, that say that new apartment blocks must be built to consume less energy, which in the end will lower the impact on the climate.One way to make the housing sector more environmentally sustainable, is to produce energy issions that are bad for the environment, for example to build wind turbines close to or even on the buildings, so called urban wind power. The scope for this report is to see if urban wind power could be a sustainable alternative for the residential area that Svenska Bostäder plans to build in Albano in Stockholm.There are extensive scientific theories regarding wind and wind power, and a literature study is made to investigate past knowledge in the area. Efforts have been made to find earlier trials with urban wind power and, both scientific research and trials where urban wind power actually has been installed. The theory chapter deals both with the wind itself and how electricity can be generated from wind.

In the essay the author examines how pilgrimage can be used as a tool to radicalise democracy in a late modern society marked by neoliberalism. Applying a dialectic perspective on social movements the essay puts forward how the pilgrimage movement Pilgrim?s Walk for Future, administrated by Church of Sweden, is working in line with the historical pilgrimage theology - a modern critical ecclesiology- to mobilise political action to prevent climate change. The result of the study shows how PWFF meet the neoliberal hegemony with a mobilisation of alternative values beyond the order of capitalism, in line with Christian theology and tradition. The mobilisation is made possible by new forms of identifications with oneself and the social world that meet a modern power/knowledge- regime based on rational thought, and which questions norms and practises by paying attention to their negative effects on nature and on human life in general.

A reform of higher education in Sweden in 1993 led to stiffer competitive climate among educational institutions. The reform meant that educational institutions now had the opportunity to plan their curriculum autonomously. Prior to the reform educational planning was restricted to the Swedish government. The new rules spelled a greater opportunity for educational institutions to profile themselves based on their educational offerings. The higher degree of competition means that marketing becomes increasingly important when recruiting new students.

Den globala havsnivåhöjningen är en direkt följd av den globala uppvärmningen ochkommer i framtiden påverka stora områden i kustregionen. Syftet med detta arbete äratt öka förståelsen samt se hur Gotlands strandängar samt kustområden kan påverkas avhavsnivåhöjningen år 2100 och se vilka eventuella följder detta kan leda till. Metodernasom har använts är GIS-analys och litteraturstudier. Höjdmodeller med olika upplösningjämfördes även för att undersöka vilka som lämpar sig till en liknande analys införframtida studier. Resultatet visar att vid en havsnivåhöjning på 1 m kommer 97 % avstrandängarna försvinna och vid en havsnivåhöjning på 2 m försvinner 99 % av degotländska strandängarna.
