Milk production in dairy cows and goats : a case study in the Nyando district inSouth-Western Kenya
Water is an essential factor for both people and animals, and access to water is therefore of great importance. The water access also largely determines the availability of food for people and feed for animals. The aim of this study was to survey the affect of water access on milk production from dairy animals. The study included nineteen farm visits that were made in the Nyando district in Kenya between February and Mars 2011. Farm visits included interviews with questions about for example number of dairy animals, milk production, water access, feed and water routines.
Miljökonsekvensbeskrivning för en utökning av befintlig djurhållning :
In the last few years the environment becomes more watchful, even for us farmers.
All agricultural enterprises that exceed 200 animal units must be tested according to
regulation of environment. A farm business with 200 animal units and more is classed
?environmentally hazardous activities? and has to make an environmental impact
assessment for the business you have today, and the activity after expansion.
Before you can construct a building and expand the numbers of animals is a lot of
applications to make. I have in this project restricted me to establish a environmental
impact assessment and a consultation foundation.
To make a environmental impact assessment is the big part of the application. The
environmental impact assessment take a lot of time and you need skills for all the rules
in the environmental code to be abele to make an environmental impact assessment
approved.
The environment codes purposes (1 kap 1 § Miljöbalken) is to rule the laws.
The purpose of the environment code is to promote sustainable development which will
assure a healthy and sound environment for present and future generations.
Definitions of a ?environmentally hazardous activities? 9 kap 1§ Miljöbalken) shall
mean the discharges of wastewater, solid matter or gas from land, buildings or structures
onto land or into water areas or ground water.
Översvämningskartering av Vombs ängar
Vomb meadows is an area well knows for its rich bird life. During the 19:thcentury until mid 20:th century, the meadows were flooded annually in order toincrease the hay yield. The river Klingavälsån situated along the west side of themeadows, used to be a shallow river, meandering across the landscape. In the1940?s the river was straightened and made deeper.
Bland brons och järn - spåren av metallhantverk från Bornholms yngre järnålder.
This essay is about Late Iron Age settlement and its production. I want to define the nature ofthree different workplaces on Bornholm, Denmark, and compare them. My aim is to see if itis possible to define a workplace through the traces of the craftsmanship. Several materials areselected in this essay and the analysis provides different perspective on workplaces in the LateIron Age in Scandinavia. The results of the analysis between the three workplacesAgerbygård, Baggård and Kanonhøj shows that Baggård have more traces of melting of bronsthan any other of the places.
Översvämningsmodellering av ett dagvattensystem
Storm water management has become a more important matter as urban areas are expanding and natural areas are being exploited. As nature landscapes are being converted into hard surface areas storm water flow is affected both in terms of velocity and size. A flow increase can easily result in a flooding if the dimensions of the pipeline system are inadequate. Considering predicted upcoming climate changes, flooding?s may become more common in urban areas in the future.
Tjänligt vatten i kranen - Membranteknik gör det möjligt : En utredning av pilotförsök i Glemmingebro
Nanofiltration is a proper way of preparation of drinking water. The process has a lot in common with reverse osmosis where a semipermeable membrane is used to separate a pure water flow from the remaining water. A pilot plant was used to ensure that nanofiltration is a suitable technology for a specific waterworks station in Glemmingebro, Ystad. The purpose was also to find out if a pH-adjustment is needed for feed water in a possible full scale plant. In this case nanofiltration is used mainly to remove sulphate and calcium since the raw water contains concentrations of these substances which exceed the limits for potable water. It is important to receive a high recovery (RC), otherwise the deliviery of water won?t be high enough.
An Iron Lady for an Iron Throne
Syftet med denna uppsats är att undersöka hur kvinnlighet framställs för att konstruera feministikonen Daenerys Targaryen i TV-serien Game of Thrones. För att uppnå mitt syfte har jag analyserat Daenerys karaktär samt personer hon interagerar med i serien. Jag har använt mig av en semiotisk bildanalys. Min teorianknytning utgörs huvudsakligen av feministisk medieforskning samt feministiska åskådningar. Materialet för min studie utgörs av fem scener från serien.
Frost hardiness of grapevine cultivars as affected by ground cover under Scandinavian conditions
Cultivation of grapevine is novel under Scandinavian conditions. We studied the impact of ground cover on frost hardiness of grapevine cultivars in Northwestern Scania in a two-factorial trial with four cultivars Solaris, Pinot Gris, Siegerrebe, Ortega and three kinds of ground cover (open soil, plastic cover and gravel). The study was conducted in a grapevine orchard, planted in May 2009, in Broddarp on Bjärepenisula Sweden (N latitude 56°; longitude E 12°). Soil and air temperature were monitored continuously.
Frost hardiness measurements were performed every second week from late September to early December 2009. Frost resistance, LT50, was determined by electrolyte leakage measurement of the upper stems after artificial freezing at -15 °C.
Vem för de törstigas talan? : En studie av debatten kring vattensektorn
1.1 billion people are today living without sustainable access to improved water. The debate over the water sector has been dominated by the discussion over whether public or private actors are the most competent to manage it. In this paper the arguments pro and contra the two positions are presented to try to overview the debate and to try to find new ways to approach the question of the people living without clean water. By examining possible alternatives towards the discussion of public and private actors, it might result in some new approaches on how to move closer towards a solution. One alternative is local, small- scale projects which focus on the situation of the targetgroup in most need.
Avgränsning av tillrinningsområden till grundvattenmagasin : vilken information ger berggrundens överyta?
Delineation of recharge areas for aquifers is performed in the groundwater mapping process at the Swedish geological survey, SGU. This work is time consuming and performed manually. It is therefore desirable to develop a more general and repeatable method for defining recharge areas for aquifers.The purpose of this study was to investigate two other possible methods to delineate recharge areas for aquifers. The first method was to examine the possibility of using the topography of the bedrock to define the recharge areas for aquifers. To enable this, a method for generating the topography of the bedrock was developed.
Riskbaserat provtagningsprogram för mikroorganismer i Gäddviks vattentäkt
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.
Vattensänkningar : en analys av orsaker och effekter
There are records of lowering of the water level in a lot of the Swedish lakes from the middleof the 1700th century. The aim was gaining more areable land to meet the needs of more foodto support the expanding population. In areas with top soil which contents of clay or loam asin the southwest of Scania in southern Sweden this was proven to be a successful wayexpanding the total outcome of the harvest.The studied area in the northeast of Scania, though, consists of morain with a lot of mires -much less nutritious conditions. When the water level is lowered the atmosphere gets accessto the peat. The dissolving of the organic matter that has been suppressed by the lack ofoxygene below water level continues.
Lakningsförsök med furubarksflis : en utredning om utsläpp av fenolföreningar samt metallsorption
The filters used today to purify water are often expensive and the need to find new filter materials is substantial. Studies of pine bark have shown that this is a material that may be used as an alternative to conventional filter materials, such as activated carbon. However, the study of pine bark has shown that a leakage of phenolic compounds may occur when using the material for water purification. Therefore, the purpose of this report is to investigate the release of phenols from pine bark, in order to evaluate the use of pine bark as a filter material. Another assignment is to investigate the amount of metals adsorbed by the filter material.
Hur mycket "mjölk" ska det vara i mjölken, och hur styr vi det?
In most countries, the dairy industry focuses on the volume of milk produced instead of its composition. This results in a high content of water and a lower proportion of fat and protein. A high proportion of water is not desirable when processing the milk into various dairy products like cheese, cream and milk powder. High water content also increases the costs for transport and storage, and also an unnecessary, albeit marginal, strains on the world?s water reservoir.
Habitatpreferenser hos tjockskalig målarmussla (Unio crassus) med avseende på vattendjup och beskuggning.
The thick-shelled river mussel (Unio crassus) is a red listed species classified as Endangered (EN) and is also considered within the Habitats Directive. The distribution in Sweden is fragmented and it is mostly occurring in the south eastern parts. We investigated the presence of Unio crassus in a section of the stream Storån, Östergötland County, from Falerum to the inflow into Lake Åkervristen. The environmental parameters investigated were water depth, bottom substrate, shading, water velocity and the slope over the water surface. In this thesis I have focused mainly on water depth and shading, comparing sites with and without mussels.
