Breeding practices of Red Maasai sheep in Maasai pastoralist communities

A survey was undertaken to understand sheep management, breeding practices and selection criteria for Red Maasai sheep in Maasai pastoralist communities in Kajiado District, Kenya. Differences between North and South Kajiado District were investigated to gain knowledge about farmers having different prerequisites and how it can affect the sheep production. The reason for keeping sheep and the specific breeds show the multiple objectives of the Maasai farmers. Adaptive traits, such as resistance to diseases and droughts, and productive traits, such as increased growth and carcass weight, were both ranked highly. In addition to this, the sheep has a social and traditional value in Maasai culture.

INVERKAN AV HAVSF?RSURNING P? PROTONERBARA ORGANISKA F?RORENINGARAS EKOTOXICITET

Resulting from anthropogenic carbon dioxide emissions, average surface seawater pH is estimated to Decline from today's approximately 8.05 to between 7.78 and 8.03 towards 2100. For ionisable organic pollutants, changes in pH can lead to a change in the degree of ionisation, which could influence the ecotoxicity of a compound by altering its bioavailability. In this study, potential changes in ecotoxicity of ionisable organic compounds resulting from ocean acidification are examined. This is achieved partly by conducting a literature review, analysing existing literature that investigates this relationship. Potential changes are also evaluated by examining marine ecotoxicity data for ionisable organic compounds on the watch list pursuant to Directive 2008/105/EC of the European Parliament and of the Council, as well as on the list of priority substances according to the 2022 proposal for amending the Water Framework Directive (2000/60/EC).

Hur en övergång till ett automatiskt mjölkningssystem påverkar juverhälsan :

Automatic milking systems (AMS) have been in commercial use since 1992 and have since 1998 increased a lot. The objective of this study has been to examine the development of udder health on farms converting to AMS. The study also included a comparison of how udder health developed depending on how farms handled cows with mastitis. This was because farms choose to either milk cows with mastitis in a separate barn or in the milking robot. Other studies on udder health on commercial farms have shown that somatic cell count increases both among individual cows and in the bulk milk when converting to an AMS. No differences between before and after converting to AMS in the proportion of cows treated for mastitis can be found in the literature.

Demokratins tjänare eller medielogikens lakejer? : En studie av fyra tidningars gestaltning av politik i samband med riksdagsvalet 2014.

From a democratic viewpoint, the way in which the media frames politics is essential. Should issue frames be left out in favor of other types of frames, it could result in voters struggling to make informed decisions come Election Day. What is more, research shows that game frames may cause lack of confidence in politicians and declining political interest. Against this background, the present study aimed to find out how two broadsheets, Dagens Nyheter and Svenska Dagbladet, and two tabloids, Aftonbladet and Expressen, framed politics in connection with the 2014 Swedish parliamentary elections. The thesis also intended to identify possible differences between the two newspaper types and to make tentative comparisons with previous studies so as to be able to comment on framing developments.

Kina- och Rysslandsfonder : En jämförande studie i nedgång och uppgång av den svenska börsen

Purpose: Aims of this paper is to evaluate a comparative study between China and Russia funds in respect of the risks and returns. We also want to examine what has affected the funds in their respective domestic stock market.                                                            Method: The study is based on qualitative methodology to complement the quantitative survey by first gathering of secondary data from Morningstar, and fund manager´s stories on fund and banking companies' websites.  Primary data is conducted by the interview with fund manager. The sample consists of all land funds for China and Russia has found more than 10 years on the stock market.Results and Conclusion: The survey shows that China funds will generate better in Decline than Russia Funds in both return and risk-adjusted Sharpe ratio. Because the China funds had better risk diversification and its holdings spread across different industry area while Russia funds is more directed towards oil and gas industry.

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.

Svenska sojabönor - finns marknadsmöjligheter?

The large-scale soy cultivation has negative consequences for the habitat of local populations because of the intensive use of pesticides and the destruction of rain forests and eco-systems. GM soya, varieties are often used. The majority of Swedish people, however, do not want GM products in their food. It will be hard in future to ensure GM free food, particularly foods that come from countries where GM crops are grown on a large scale. It is very difficult to avoid cross- contamination when both GM and non-GM crops are grown in the same area.

Leder storskaliga landinvesteringar i jordbruk till hållbar utveckling? En fallstudie av projektet ProSavana i Moçambique

Large-scale land investments is not a new phenomenon, but increasing prices on food and agrofuels have inflated prices on land and has led to an enhanced interest in landinvestments from a range of different actors. The ProSavana project in the Nacala corridor in the Nampula province, northern Mozambique is a large-scale land investment with the purpose of establishing intensive commercial agriculture and is planned to be implemented this year (2013). The project is financed by Brazil and Japan in collaboration with the government of Mozambique. It is not quite clear how large-scale land investments affect the areas they are implemented in and how they can affect the possibilities for sustainable development in these areas. Both opportunities and problems can be observed within the social, economic and ecological dimensions of sustainable development.

Äganderättslägenheter : En studie om vilka faktorer som hindrar a?garla?genheterna att sla? igenom pa? den svenska bostadsmarknaden

Bachelor of Science, Construction and real estate economics at the University of Halmstad, Sweden, 2012. Author: Emilia Bjuvensjo? and Emma Davidson Advisor: Sven-Ola CarlssonExaminer: Kent Sahlgren Title: Condominiums ? A study of what factors are preventing condominiums from having a breakthrough on the Swedish housing market.Background:In Sweden condominiums have been discussed over and over again during the past 100 years. The government decided that on the 1st of May 2009 they would introduce a new kind of housing-form, condominiums. Ever since the new law came into force, no major changes have been done in the Swedish condominium market.

Utvärdering av den svenska cykelhjälmslagen för barn under 15 år : Analys av nationella trender i cykelrelaterade huvudskador mellan 1998-2011

Introduction: In January 2005, a nationwide mandatory bicycle helmet law for children under the age of 15 was introduced in Sweden. In the current study, the effect of this law was evaluated by analyzing national trends in hospital admissions due to bicycle-related head injuries during the period 1998-2011.Methods: An interrupted time-series design with segmented regression analysis was used to evaluate the intervention effect on head injuries as a percentage of all injuries (%HI) among cyclists in age- and sex-specific groups. Effect was measured as a change in level and/or slope of the trend at the time of legislation.Results: A total of 35261 cyclists (0-54 years) were hospitalized due to a bicycle injury during the study period. Linear regression analyses of the entire study period (not segmented) showed significant year-to-year decreases in the %HI of 1.3-1.7% in all age and sex-specific groups (p < .0001). Results from the segmented regression analysis showed that, at the time of legislation, a significant drop in level occurred among males under 15 years (-4.5% [95% CI: -7.7% to -1.3%], p = .01) and a significant change in slope occurred among females aged 30-54 years (-1.6% [95% CI: -2.9% to -0.2%], p = .025).Conclusions: The law seems to have had an effect on males in the target population (<15 years).

Challenges and Opportunities in Swedish Apiculture

Bees are of importance for the global food security. In Europe 84% and in the World 35% of all the agricultural crops are dependent of animal pollination (Winfree et al., 2011:1). In agricultural production there is a huge lack of pollinators (Azien & Harden, 2009). A problem that is widely spread. In Sweden the problem becomes clear when looking at the statistics of the number of bee colonies during the last 20 years, where it has been a Decline with 63 % (Statistiska Centralbyrån & Jordbruksverket, 2011).

Hur kredithandläggare lantbruk i sina kreditgivningsstrategier beaktar den potentiella riskfaktorn att säkerheten i form av åkermark faller i värde

The increase in farmland value in Swedens plain areas is a well known fact in today's Swedish agricultural. In connection with the fluctuating prices of crops and inputs, are increasing the risk exposure to agriculture. The increased value of agricultural land has in Sweden over the years been due to a high demand for land that has existed and exists in Sweden. The increasing demand is linked to a structural rationalization of Swedish agriculture, leading to fewer and larger farm units (www, privataaffärer, Carl Johan Jurss).The purpose of this study is to examine the potential risks associated with the farmland value falls or remains unchanged, according to a farm credit administrator's perspective. The idea is to get a picture of the main factors taken into account when lending and the problems with falling or stable land prices into account when lending.

Skördesystem i vall, skördens storlek ochfoderkvalitet

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.

Samspelet mellan ekologi, produktionsförhållande, politik och sociokulturella faktorer gällande Östersjöns torskbestånd från 1970-talet till 2003

The study begins with a historical background over the fisheries development in North America and in the Baltic Sea area in Finland and Sweden. As we can see the fisheries development depends on the interaction between ecology, state of production, politic and also social factors. In Sweden the fishery politic has changed over the period of the study. In the 1970: s the main politic focus was on the fisheries progress, expansion and rationalization. The State in Sweden took a vast part in this development and gave economic support.

Fertility before and after installation of Herd Navigator?

The fertility of dairy cows is of great importance in order to maintain high production. The Decline in fertility of dairy cows the latest decades can have several explanations. The large emphasis on high yielding cows and the negative genetic correlation between milk production and fertility traits could be one of the main factors for impaired fertility. To find heats and inseminate the cow at the right time is crucial to receive high conception rate. Delaval has, in corporation with FOSS, developed Herd Navigator which is a management program that measure four biological parameters in the milk; progesterone, betahydroxybutyrate, lactate dehydrogenase and urea.
