Ryttarens tygelsignalers inverkan på hästens beteende och trycket i tyglarna
This essay derives from the concern that horses ridden with a bit in their mouth can be subjected to strong pressure from the bit if the horse and rider do not understand each other. The horse's mucosa membrane and the tongue are very sensitive tissues (Cook, 1999; Manfredi, 2005; Oliveira, 2005; Terada, 2006) and the bit can then be a source of pain and discomfort. The training of the horse should therefore always be a step by step process and as the horse develops difficulties are increased. Oliveira (2005) suggested that high demands can be placed on the horse but to be successful in the training it is essential to be content with small progress and reward the slightest desired response from the horse. This corresponds with the principles of operant conditioning with negative reinforcement.
Nedbrytning av propylenglykol i uppsamlingssystem för avisningsvätskor : En studie utförd vid Stockholm Arlanda flygplats
Deicing fluids based on Propylene glycol are used at Stockholm Arlanda airport to remove or prevent ice on aircrafts. The high oxygen demand of propylene glycol can cause oxygen depletion in rivers downstream from the airport if not collected. Mass balance calculations made by Swedavia indicate that the actual amount of gathered propylene glycol is underestimated. Suspicions that propylene glycol is degraded in the stormwatersystem designed to collect deicingfluids, called the B-glycolsystem, have to be investigated in order to establish with certainty that no propylene glycol in other ways leaves the B-glycol system.The purpose of this study was to determine if degradation of propylene glycol is present in the B-glycol system and also to estimate the extent of the degradation. Propylene glycols high biological oxygen demand can cause oxygen depletion in waters downstream from Stockholm Arlanda airport if not collected.
Utvärdering av traktplanering på Holmen Skog
This study has been performed with the help of forest machine operators in order to improve the forestry planning at Holmen Skog Örnsköldsvik-region.
For Holmen Skog forestry planning is basic for a successful forestry. In a survey I have investigated what can be improved in some areas that are planned for harvesting. The result of the investigation will be used to support the machine operators as much as possible. The study has generated 49.5 % of responses and because of this low response rate, no clear conclusions to anyone else except the responding machine operators can be drawn.
It has been proved that there are some details in the forestry planning system that are inadequate, such as marked routs for trails, tractor paths and buffer zones against streams.
The quality of forestry planning varies greatly between different locations, as much as 50 % of the responding machine operators thought so. Over 40 % of the responding machine operators claim that the information from Holmen is insufficient.
One thing that would improve the forestry planning within Holmen would be to educate all forestry planners and then do continuous follow-ups..
Att leta efter kännskap : Hur lärare ser på utemiljön som en miljö för lärande
In outdoor education the empirical outdoor experience is an important basis for a learning process ? the teacher can affect learning with the choice of location. In order to develop the model in school, we need to build on teachers' perception of how their every day schoolwork looks like. This paper takes as its starting point at three teachers' perception of their learning environment and outdoor environments as well as a theoretical model of the site's importance in the learning process. The paper addresses both the importance of a structured and a unstructured meeting with outdoor sites.
Blogg + Svenska = SANT? : Bloggande i undervisningen i svenska på gymnasiet
AbstractIn this text the attitudes towards and using of blogs in teaching Swedish toteenagers will be explored. The results are based on a survey made amongst 17teachers and 58 students from all over Sweden. The end results show that theusage of blog still hasn?t found a permanent way into the classrooms, but has anappeal to and is being used by predominantly younger teachers both, male andfemale, with a positive response from students regardless of gender. Theconclusion is that using web tools like the blog is an easy first step for schools toconnect to the digital society of the 21stcentury and take advantage of the perksavailable in the digital classroom.Svensk titel:Blogg + Svenska =Sant? ?

Brunstvisningsförmåga hos mjölkkor- en beteendenstudie
Oestrus in dairy cattle has changed over the last decades; the intensity of oestrus has declined and the duration decreased. Several studies have shown that not all dairy cows stand to be mounted, and that oestrus expression in many cases may be characterized by other behaviours. The aim of this study was to investigate oestrus behaviour in a herd of todays? high producing dairy cattle. The study was carried out at Jälla naturbruksgymnasium in Uppsala during one week in January 2011.
Framtidens begravningsplatser : en historisk tillbakablick, dagssituationen och visioner för framtidens gestaltningsuttryck
The purpose of this article is partly to find out how
the burial grounds are used today and the needs of its
visitors, but also to develop the character and
expression of future burial grounds. My suggestions
focus on burial grounds without religious attributes;
something that, according to the burial law
(Begravningslagen, 1990:1144), the manager of the
burial ground is ordered to obey. In my design I aim to
fulfill any requests regarding the place of burial that
have been raised during my study.
I have chosen the history of burial grounds as my
starting point and will subsequently discuss their
significance in today's society. I describe what
distinguishes the burial ground throughout history
from medieval times and onwards. Tradition and
religion are closely linked regarding burial rituals.
Privatskogsägarens nettoinkomst vid avverkning under perioden 1952-2008
During the period 1952-2008, real prices of wood before taxes and charges declined. However, the actual net income has not changed by the same percentage as the price list, because taxation, driving costs and the ability to make deductions has changed. This report considers the inflation by using the Swedish consumer price index. Net income refers to the remaining income when relevant costs, taxes and fees have been paid.The purpose of this study was to examine how the private forest owner's real net income has evolved over the period 1952-2008 for three categories of forest owners. These three categories are1.
EU:s medborgarinitiativ : En framkomlig väg för att minska det demokratisk underskottet?
The European Union is struggling to maintain democracy and tries to increase the participation among the citizens in Europe. The European Citizens? Initiative, ECI, is a platform established by the European Commission to allow citizens to propose new legislation. ?Water and sanitation are a human right! Water is a public good, not a commodity!? is the first ECI that has met the requirements.
Hur värderar människor utemiljön och dess funktioner? : två fallstudier - Tarapoto, Peru, och Uppsala, Sverige
This essay discusses people's perception of what is important for their well-being where they live. The main aim has been to find out what factors in the outdoor environments of the city are appreciated and why they are valued positively. A comparison has been made between Uppsala in Sweden and Tarapoto in Peru to see if, and in that case what, differences can be found in the values of people.
I chose to carry out a survey study that got a response rate of 57 persons in Tarapoto and 63 in Uppsala.
The results show that there are some common basic values, but on the whole the outdoor environments are valued differently in the two cities. In short, the Peruvians value functionality, cleanliness, small distances to family and service, while the Swedes value a central location and short distances to friends apart from functionality and good service opportunities. Conceivable reasons for this might be for example different cultural prerequisits, material standard and climate.

Kvantifiering och kartering av föroreningstransport inom ett avrinningsområde
The aim with my master thesis is to develop and test the applicability of methods to quantify and map solute advective travel times and pollutant transport at the catchment scale. Such quantification and mapping can increase the understanding of catchment-scale pollutant transport in general and contribute to the identification of the main sources of water pollution and the most efficient measures to reduce such pollution. The study area is the catchment of Oxundaån, about 20 km north of Stockholm. For detailed GIS modeling of water flow and catchment-scale contaminant transport in water, I´ve used new high-resolution elevation maps, land cover maps and soil maps combined with other available relevant data..
Kommunal samverkan mellan räddningscentral och POSOM - En fallstudie av Tsunamikatastrofen
This report is an evaluation of the cooperation between the rescue command centre and the POSOM-groups (?Psychological and social support?) after the Tsunami catastrophe in December, 2004. The report describes the interaction between these two municipal administrations, what services the rescue command centre provided and how they gathered information. Finally the author suggests different solutions to how the collaboration within these different municipal administrations can be increased and improved in future times of crisis..
Att optimera samhället inför klimatförändringar : Sårbarhet och anpassning på dagordningen
This thesis examines the ways in which adaptation and vulnerability are framed in national and sectorial policy-documents dealing with expected societal impacts of climate change. By using theories of discourse and ideology, the analysis aims to find and understand important ideas and presuppositions that are explicitly or implicitly expressed in these documents in order to make possible and tangible the institutional production of policy within the potentially far-reaching problematique of climate change adaptation and vulnerability. The analysis shows that there are two main perspectives through which vulnerability and adaptation are framed; one focusing limits to societal robustness; and one contesting the institutional capacity to implement adaptations. The author understands these framings as complementarily optimizing preconceived social and economic relations, something that might, in fact, reduce the response capacity of people..
Den önskvärda demokratin? - Om demokratins tillstånd och försvar
This thesis deals with non-wanted political parties e.g. right wing populism. How should a democracy handle these opinions? So far these parties have been neglected and not even considered as real parties. By excluding them from the debate and the political arena, media and more established parties have seen them merely as a threat than as democratic parties.
Mät och loggningsutrustning för spänningstransienter
To be able to measure high-surge voltages and transients with short rise times youneed measuring instruments with a high sampling frequency and large Bandwidth.These surges and transients occur primarily at lightning but can also occur at forexample at connecting errors at an electrical switch-gear. This report describes thework with finding two solutions for measuring and log data from these surges andtransients. One temporary solution where a measurement program has beendeveloped. A second solution where different company solutions have been analyzedto decide which fits best. For these measurement solutions two solutions for bringingdown the voltage has been used.
