Uppväxtmiljö och i uppväxtmiljön förvärvad djurvana hos elever vid naturbruksgymnasium : Home environment and in home environment acquired animal experience in students of agricultural college
In all types of learning situations, it is important to find each student where they are at the moment in knowledge. I have reflections about what animal experience students have with them when they begin their education. This thesis is about what home environment and in home environment acquried animal experience student at agricultural college have. This work is based on data collected through questionnaire survey done in two agricultural colleges in middle Sweden in the spring of 2007. Questions were divided into four blocks, historical data such as on the environment in which pupils are growing up, animal habit, why they read on agricultural school and future data on what plans students have for future education and careers.
Impact of Regulations on Innovation Performances in EU:
Innovation has been identified as one of the key factors for economic growth long ago. However, the emergence of ?knowledge century? further strengthened the role of the concept since proper management of the knowledge is essential to make the best out of the innovative capacity of the companies as well as the countries. This necessitates a balanced intellectual property rights (IPR) systems, since these rights provide the basis to solve the market failures faced by innovating firms by creating property rights over knowledge. There is an inherent dilemma between invention and diffusion.
Hållbar utveckling + turism = sant? Intressen inom projektet Exportmogen destination i biosfärområdet Vänerskärgården med Kinnekulle
This essay examines whether, and if so to which extent, the project Export MatureDestination in the Biosphere Reserve Vänerskärgården with Kinnekulle can combine the goalof the tourism industry, i.e. to double tourism between 2010 and 2020, and the goals of theBiosphere reserve, i.e. sustainable societal development and a sustainable biosphere economy.The aim is to examine how key individuals in the project approach sustainable developmentand economic growth, representing the two main interests in the area. Examining the state ofthe two interests the following examples are used: the position of sustainable development inregard to economic growth, the opportunities and challenges in the area and unity concerningthe goals of the tourism development in the region. The study is conducted through qualitativeinterviews with key individuals and a descriptive document analysis of the most importantpolicy documents.
????????????Pedagogers syn på utomhuspedagogik
The purpose of the research is to find out how the teacher of the pre-school looks at the value of the nature Pre-school. To get an understanding of what the nature pre-school enviorment can bring, we are talking about learning, knowledge, and experience combined with the everyday lessons learned from the natural world. The research is a stepping stone on the pre-school teacher?s thoughts and reflections of what a nature pre-school is. This is grounded in a view of how having options for alternative schools lead to wider research, and all conclusions where formed after multiple interviews and analysis.The results showed that the teachers involved are very positive to the nature pre-school environment and learning process.
Angiogeneshämmare som behandling mot metastaser : var forskningen är idag och vart den är på väg
Syftet med denna litteraturöversikt är att göra en utvärdering över de mekanismer som är viktiga vid tumörmetastasers nybildning av kärl s.k. angiogenes och med vilka metoder man kan hindra dem.
Tumörceller som prolifererar ohämmat utan att stimulera angiogenes begränsas av brist på näring och ineffektiv bortförsel av slaggprodukter och kan därför sällan växa och bli större än cirka 1mm. Detta medför att även om det kliniskt finns många små metastaser i en patient så
innebär det sällan något problem för patienten. Om tumörcellerna däremot muterar så att de kan stimulera angiogenes så tillåts tumörerna växa sig större och förstör då kringliggande vävnad vilket tillslut resulterar i patientens död.
Mycket forskning görs i nuläget inom ämnesområdet och man har som mål att med hjälp av angiogeneshämmare göra cancer till en kronisk men hanterbar sjukdom istället för den
sjukdom med dödlig utgång som den ofta är idag.
Den första angiogeneshämmaren som godkändes för medicinskt bruk i USA var Avastin (Bevacizumab) som är en antikropp som binder till och oskadliggör vascular endothelial
growth factor (VEGF), vilket är en av de faktorer som stimulerar angiogenes. Detta får som följd att de tumörer (60 % av alla humana) som uttrycker denna faktor hämmas i sin tillväxt.
Effekt av myrsyra och beta-laktamas på penicillin- och S. aureus-halt i mjölk till kalvar :
A sample of milk inoculated with S. aureus was treated with penicillin, and Antipen (a new commercial product containing penicillinase) was added. To another sample with S. aureus and penicillin, formic acid to pH 5 was added, and to yet another sample, a combination of formic acid and Antipen was added. Controls with no penicillin were treated in the same way.
Samband mellan överlevnad, tillväxt och pälskvalitet hos lammen och fruktsamhet och modersegenskaper hos tackan
There are several factors influencing the profitability of production with sheep. Two of the most important factors are ewe fertility and lamb survival. Also growth capacity of the lambs is important. This paper aims to review correlations between the ewe?s fertility and maternal behavior and lamb survival.
Internationella konventioners arbetsrättsliga regleringar angående barnarbete i Pakistan - implementering och förbättringsstrategier
Every single child has the right to a childhood as well as a future. The labor regulations within the international conventions exist in order to make sure that these rights are looked after, but the ratification of the conventions is just the beginning. In order to receive the results which are set by the conventions, it is crucial that the implementation is successful. The politics of the country have to change and improve in order to achieve compatible laws, but also the population has to be given the opportunity to obtain education and knowledge about their human rights. Children who are forced to work at a young age, often under inhuman conditions, are not only deprived of their childhood but also of the chance to develop into an independent individual at the same time as this interferes with their education.
Gremmeniella abietina-epidemin 2001 : har skogen återhämtat sig?
The fungus Gremmeniella abietina causes damage to conifers that can lead to tree death. In 1999 and 2001 the pathogen caused severe attacks in Sweden, where about 500 000 ha of pine forest were affected. Trees of all ages were attacked, but mainly forests between 30-60 years that were ready for their first commercial thinning. After recommendations from the forest agency, sanitary fellings were made to trees that had more needle loss than 85%, a total of about 50 000 ha. Economic losses have been estimated to more than one billion SEK.
Hur påverkar inavel fruktsamheten hos häst?
Inbreeding has become a problem in some horse breeds. Studies show that it may lead to inbreeding depression which affects e.g. reproduction traits. In the wild there are mechanisms that make horses avoid mating with close relatives. When selection is done by humans this mechanism is removed and intensive breeding for a few traits, for example good racing results, can become a problem.
Simulation of rattan harvests in Indonesia : different harvesting pressures and the resulting patterns
The objectives of this research were to determine whether the natural rattan resources in Sulawesi, Indonesia can cope with the strongly increased harvesting pressure that has occurred over the last centuries. I was furthermore looking for patterns in the rattan population dynamics that might give a hint on how the harvesting system could be improved to ensure a maximum sustainable yield. To
answer these questions, I developed an individual-based model to analyse the dynamics of rattan growth in connection with rattan harvests by locals to identify sustainable levels of rattan harvests around villages in Sulawesi, Indonesia. Scenarios with different harvesting intensities were run to compare the change in harvest amount. For a given harvesting pressure, scenarios with a high number of harvesters and a low harvesting frequency had the same effect as scenarios with high harvesting frequencies and a low number of harvesters.
Jobba till 75 år?! : Trygghet och egoism i den svenska välfärden med pensionssytemet som exempel
The purpose of this study was to try to understand the Swedish population regarding the perceptions of the Swedish welfare system, based on the reactions that occurred after Sweden's Prime Minister Fredrik Reinfeldt's statement about raising the retirement age. Our results demonstrate that the reactions on changes in the pension system in fact rooted in a safety factor and not the change in the pension system itself, through which the Swedish welfare system acts as a safety net for the population. Further the results shows that these safety factors create a form of egoism. With an interaction between empiricism and theory, where the starting point of the material was of an inductive approach, the material abstracted into different levels from which the result emerged. The focus of this study lies in the understanding of how human beings act according to one's need for security in major changes, which may be of importance to a comprehensive understanding of changes in social structures..
En studie om hur Montessoripedagoger motverkar stress hos barn i Montessoriförskolan
The purpose of this essay is to study the film culture in South Africa in a national cinema-context, focusing on the relationship between anti-apartheid film from 1974-1994 and the film in South Africa today. By pitching the South Africa-specific works of Lucia Saks and Jacqueline Maingard against the over-arching debate on national cinema as formulated by, amongst others, Stephen Crofts and Andrew Higson, this study aims to find whether or not a specific South African national cinema have existed, and exists today, or not. The study finds that an underground culture of documentaries and short films made by and for the black population has been in place since the apartheid, and the distribution method on video and television is still being used to reach the black population today. By re-examining the concepts of both the national, and of national cinema to also include film on video and television, the study shows that South Africa has indeed a film culture that can be called a national cinema..
Experimentell studie av sensationen hos färger
There are a large number of studies on colour and its influence on human feelings, but thereare only a few studies on the association between feelings and colour combinations. Thisstudie investigates the association between colour combinations consisting of three equallysized colours and the feelings they convey. The methodology used in this studie follows theinstructions from the Nippon Colour & Design Research Institute (NCD) in Japan, NCD havestudied consumer psychology towards colour and colour combinations for several decades.This study used semantically differential scales to evaluate existing colour combinations fromNCD to descriptive adjectives and creation of new colour combinations to explore therelationship between colour combinations and conveyed feelings. A total of 69 peopleparticipated in the tests. The main conclusions formed by this study are: (1) the feelingsconnected with the colour combinations differ partly between the Swedish population and theNCD and (2) the Swedish population have similar feeling associations to most colourcombinations, except for trend dependent adjectives such asmodern, cool etc.
Askans inverkan på beläggningstendensen i ett biobränsleeldat kraftvärmeverk och växtplatsens påverkan på askegenskaperna :
This report was written by Sofia Ericson and describes the degree thesis with the title: ?Connections between the growing site of bio fuel, the chemical composition of bio fuel ash and the deposit growth in a bio fuel fired boiler.? The purpose of this degree thesis was to avoid melted deposit growth in the bio fuel fired boiler at ENA Kraft in Enköping.
Potassium and sodium are known to lower the melting point of bio fuel ashes and are therefore not wanted in the trees in higher amounts than necessary for the growth. Silicon is also known to be important for the deposit growth but it is not possible to say in general if higher or lower contents of silicon is better. The relation between silicon and other chemical substances is more important than the total amount of silicon.
