Torkning av vallfrö :

In Sweden, grass is the single largest crop grown. Nearly 1 000 000 Ha grows on the fields, this is primarily used as feed for livestock. To get a good seed, you need to handle the crop carefully from planting to delivery. The part that I have been interested in, is how to dry the harvested seed with out destroying the growth in the small seed. This is very easily done if you aren?t careful during the drying period.

Hägnutnyttjande hos Aldabrasköldpaddor (Geochelone gigantea) på Parken Zoo

Reptiles are animals than have been neglected in the research for all times. Some people have the opinion that these animals have fewer needs and demand less from their caretakers. The Aldabra Giant Tortoise lives on the Aldabra atoll outside the coast of Tanzania. The Aldabra tortoise population has varied throughout the years, but today the population is around 100.000 animals. The purpose of this study was to analyze the enclosure utilization of two Aldabra tortoises, a male and a female, at Parken Zoo in Eskilstuna, Sweden.

Överlevnadsanalys och avyttringsorsaker - för ackordhäststiftelsens hästar 1967-2012

Few scientific studies have studied the subject of longevity among horses over a longer period of time. The knowledge about the Swedish riding school horse population concerning injuries and diseases is insufficient. Generally speaking, riding school horses in Sweden have a more undiversified way to work and work more hours in the arena compared to privately owned horses that have more variety in their possible use. Statistical data from the insurance company Agria have shown that horses in riding schools and education facilities have 22 % higher risk to use their veterinary insurance and 79 % higher risk to be put down and use their life insurance, compared to horses in private care. To create an increased understanding for longevity is it important to have knowledge about the different causes of culling. The aim with this study is to increase the knowledge and enable problem solving within the subject of longevity, median length of life and causes of death.

Traditional milk production in cattle in a semi-arid area in Kenya

Livestock of pastoralists provide meat, milk, blood, dung and are useful for transportation purposes. In semi-arid and arid areas with very low precipitation the herder must often walk far distances to feed the livestock. This affects the animals? production, especially of milk. Previous studies have investigated how to improve milk production in terms of milking strategies in cattle.

Hållbar utveckling- En textanalys av miljöpolicy i lokal och nationell kontext

Sustainable development is a concept that has been interpreted in a multitude of ways in different contexts. This essay argues that the discourse of "ecological modernization" has strongly influenced the way in which the concept of ?sustainability? has been constructed in Swedish environmental policy. This interpretation of the concept of sustainability offers the possibility of combining economic growth with ecological sustainability which stands in contrast to the assumptions of Deep Ecology and Green Theory. The aim of this essay is to explore how the concept of sustainability is being formulated in environmental policy both on a national level and in the city of Malmö.Considering these issues in a specific context, this essay focuses on city planning that is as an important instrument to promote urban sustainability both on national and local levels.

Kompostering av köksavfall och användning av kompost i köksträdgård i Chazuta, Peru : jordförbättring och/eller lösning på ett avfallsproblem?

All over the world the waste from human society is causing problems. In developing countries, large cities are polluted through huge amounts of wastes and people are forced to live very close to open deposits. Lima, capital of Peru, is no exception. The countryside in Peru has also a great challenge to face concerning the waste issue. Children and adults suffer from infectious diseases and contamination of the nature occurs as well. One solution to handle organic waste is to compost, which means a controlled decomposition of organic waste under aerobic conditions at certain temperatures.

Pre-treatment of grain for ethanol production during storage

Ethanol for automotive purposes is an issue much debated and researchers disagree about the benefits of bioethanol. Converting energy-rich crops into ethanol suitable as motor fuel is a complex process and continuous development and improvements of processes and material used are important steps in the work of developing environmental friendly fuels. Grain is usually preserved by drying which consumes a lot of energy. Alternative storage of high-moisture grain in airtight storage systems reduce the energy required to produce bioethanol and studies have also shown that ethanol yields are increased more than 10% in ethanol fermentations of moist grain compared to dry. Airtight storage is often not perfectly airtight so biocontrol agents are necessary in order to preserve the grain.

Organiserade samverkansnätverk: en kartläggning av en population i Sverige och en studie av styrgruppssammansättningens påverkan på framgång

Genom att samarbeta med andra aktörer på marknaden kan företagen gemensamt bli mer effektiva och konkurrenskraftiga i syfte att tillsammans uppfylla kundernas mer komplexa och specifika önskemål genom att erbjuda helhetslösningar. Detta ligger till grund för den växande nätverksbildning som många företag insett betydelsen av. Organiserade samverkansnätverk är en typ av företagsnätverk som består av ett antal små eller medelstora medlemsföretag. Medlemsföretagen verkar på en begränsad geografisk yta och målet med nätverket är att uppnå specifika affärsresultat. Syftet med denna uppsats var att identifiera en population av organiserade samverkansnätverk i Sverige samt undersöka hur styrgruppens sammansättning kan påverka nätverkets framgång.

Ungdomlig ålderdom - hur modeföretag marknadsför sig bättre hos äldre kvinnor

When the competition is getting stronger and companies must work harder to find new markets, new products and create new needs to reach growth, it appears strange that they overlook an obvious target segment right in front of their eyes. For some years ago, marketers of fashion brands feared that older women would wear their clothes, because it gave bad promotion for the young economically viable target group. Today, older women have difficulties finding clothes with right fit, style and personal taste. They would gratefully accept a brand, they felt were aimed for them. The purpose of this study is to give new ideas to companies in the fashion industry, how to reach this target group, but also be a contributing reason for older women to see the market opening for them.

Den Sociala Identitetens Inverkan På Subjektiva Bedömningar Av Att Dela Värderingar Med "Andra" - En psykologisk analys av motstridiga uppgifter i Integrationsbarometern 2004

This study examined some contradictive results in a report from the Swedish board of Integration. The contradiction was concerning the Swedish populations dismissive judgments of experience a shared ground of values between the Swedish society and those witch are generally held within Islam. These dismissive judgments were given at the same time as the population reported to have a lacking knowledge of Islam in general. To test for psychological aspects of these contradictions, the analysis was based on the theoretical ground of Social Identity Theory and Theory of Attributions. The study used an existing survey that examines people´s estimations of their own and other members of society´s fulfilling of democratic values.

Examination of mycorrhizal associations of Allanblackia stuhlmannii : a tree under current domestication

Allanblackia is a tree genus native to humid forests in West, Central and East Africa. Its fruits contain large seeds from which edible high-quality fat can be extracted. In order to create a sustainable supply chain of Allanblackia seeds, a domestication program has been initiated with the purpose to enable smallholder farmers to grow the tree as an agroforestry component and cash crop. More knowledge is required to understand the tree?s biology and possible symbioses involving soil microorganisms with plant growth enhancing poten-tial.

Hälsa och hälsorelaterat beteende : En undersökning av beteendets betydelse för den självskattade allmänna hälsan

An increasing number of health problems in the population and an uneven distribution of health between different groups in the society, have been identified as a problems and has therefore been put on the political agenda in Sweden. Thus, the purpose of this thesis is to estimate and discuss the significance an individual?s behaviour, in a number of areas, has on his/her level of health.The empirical material for this thesis is taken from a nationwide inquiry conducted in 2004,which was called ?Hälsa på lika villkor?? (Health on equal terms?) The material used consists of the answers and records from individuals living in the administrative district of Kronoberg. 9972 individuals were included in the sample and the answering frequency was 63,2%. To map and analyse the material, which was done mainly through crosstabs, chi-square tests and logistic regressions, the statistics software SPSS 11.5 was used.The parameter used to measure the health level is the individual?s own perception of his or her general health.

Arbetslöshetens bestämningsfaktorer i ekonomisk-historisk belysning - En analys av lönebildning, totalfaktorproduktivitet och löneutrymme under perioden 1911-1960.

This paper analyzes the Swedish labor market during the interwar and early postwar period within the framework of modern labor market theory. The development of unemployment during this period - according to the commonly cited source of labor union reports - represents a conundrum for research. The unemployment rate rose after the initial diverse shock of 1921 and stayed at a permanently higher level for the rest of the interwar period. This development was reversed after World War Two when the unemployment rate decreased and stayed permanently low for the rest of the postwar period until the oil price chock of the 1970s.In a first step the available sources of unemployment statistics is investigated and compared. The general conclusion is that the labor union reports overestimate the level of economy wide unemployment while being a reasonably good indicator of movements in the rate.

Behovsstudie av ett energibutikskoncept för energiförsörjning utanför elnät : ? En småskalig fältstudie i Namibia

The amount of electricity is limited in Namibia and the large distance between towns andvillages complicates the energy supply in the country. Therefore an alternative way to provideaccess to appropriate energy technologies is needed. The Government of the Republic ofNamibia (GRN) has adopted an approach of helping off-grid households by establishing EnergyShops in each region in Namibia and these shops are going to sell basic renewable energy andenergy efficient products. The Renewable Energy Efficiency Institute in Namibia (REEEI), theinitiator of this thesis, is coordinating the establishment of these Energy Shops.The main purpose of this thesis was to examine the needs of energy products for the Namibianpopulation and develop an assessment method for the Energy Shop in how to select appropriateenergy products already on the world market. The purpose was also to develop a method forchoosing an Energy Shop.

Is Home State Taxation a step forward for SMEs? An SME?s ability for growth and integration in the EU after the HST tax reform

Small and Medium sized Enterprises (SMEs) within the European Union are currently facing many challenges one being access to financing due to high risk and probability of default, another being cross-border taxation issues with double taxation and information asymmetry. Since the aim within the EU is to be the most competitive and dynamic knowledge-based economy in the world with sustainable economic growth and social cohesion it is essential that the EU operates as a single market. Despite this need, harmonization continues to be far from achieved in the area of direct taxation which also affects the integration and growth opportunities for SMEs. In the Agenda for Entrepreneurship, the Home State Taxation regime, which is based on formula apportionment, has been proposed by the Commission as one option in order to mutually recognize the different Member States? taxation systems to facilitate cross-border activities and reduce ?red-tape?.
