Näringsretention i återskapad våtmark på betesmark : studier av en mad vid Bornsjön

It is important to construct or recreate different types of wetlands and study their retention of nutrients, since knowledge of their effectiveness in this matter is poor. In 2003 a wetland was constructed on an old meadow on the western shore of Lake Bornsjön in central Sweden. The main purpose of the wetland was to reduce the amount of phosphorus entering the lake, which is the back-up water supply for Stockholm when the city cannot obtain water from Lake Mälaren. Large areas around Lake Bornsjön consist of agricultural land and the nutrient concentrations in the inflows to the lake are usually relatively high (approx. 1 mg/l total nitrogen and 0.05-0.1 mg/l total phosphorus).

Aktiebolag använder sig av en kod för bolagsstyrning för att öka förtroendet för sin verksamhet. Vi vill i arbetet undersöka om tankarna bakom denna kod även går att applicera på idrottsföreningar..

Kan kväve bevaras i dräneringsvatten från åkermarksom lagras i dammar? : ett laboratorieförsök

The aim of this thesis was to examine if it is possible to keep nitrogen in the form of nitrate(NO3-) in ponds from one season to another by keeping a high concentration of oxygen in thepond water. This hypothesis was tested by doing a lab experiment where two systems werecompared according to nitrate concentration. One system had high concentration of oxygen inthe water and one had low concentration of oxygen. Before the main experiment wasconducted I did a pilot study to test the system setup and included parameters. The result fromthis study and the main study did not show the same result.

Alkohol- och tobaksvanor inom fotboll : En jämförelse mellan alkohol- och tobaksvanor inom olika divisioner i herrfotboll

AbstractThe purpose of this study is to examine alcohol and tobacco habits in men's soccer in the in Sweden and compare those habits in different divisions. The method we used in the study was aquantitative survey report. Two teams participated in the survey, one team from the fifth divisionand one from the second division. The respondents (n=34) are born between 1977 and 1996. The results turned out to be very interesting because it both confirm and denies our hypothesis that players in higher divisions use less tobacco and alcohol than players in lower divisions.

GIS och statistik vid dräneringsområdesvis kväveläckagebeskrivning i Halland

The last decades have shown increased nitrogen leeching from soil to water recipients. This is inSweden mainly due to over-manuring of agriculture land, effectivization of drainage systems and thedeclining extent of wetlands. The accumulated amount of nitrogen in water doesn?t only make itunsuitable for use by humans and cattle, but also decreases the biological diversity as well as negativelyaffect tourism and fish industry. In the most severe cases shallow maritime grounds can be completelydepleted of oxygen due to decomposition of the increased amount algae and plankton growth.This study have the aim to describe and quantify the nitrogen leeching from the Genevad drainagebasin, located in southern Halland, Sweden.

Uppfattningar om utomhuspedagogik hos lärare i grundskolans årskurs 4-6

The use of out-door pedagogy in the school has been frequently high-lighted during recent years. To which extent out-door education was practised in the school depends on the opinions among the active teachers. The aim of this study was to examine the opinions on out-door pedagogy among teachers in classes 4-6 of the elementary school and to find out to which extent the teacher used out-door teaching. The study was based on qualitatively structured interviews with 4 teachers having different lenght of teaching experience. The results of the interviews showed that the teachers had different opinions on the definition of out-door pedagogy.

Den skeva bilden : En studie i hur brottsrapporteringen i Efterlyst ser ut jämfört med brottsstatistiken, samt hur programmets tittare upplever att de påverkas

The purpose of this thesis was to determine the tv-show Efterlyst?s (Wanted)effects on viewers when it comes to how crime, criminals and victims are portrayed in the show. In order to achieve the purpose of our the study, both  quantitative and  qualitative approaches were used We compared the image Efterlyst gives of crime, criminals and victims to statistical information from The Swedish National Council for Crime Prevention and The Central Bureau of Statistiscs. By using focus-groups we also studied how Efterlyst portrays, in the season of 2009, and how it may have affected its viewers. Our conclusion was that there are important differences between how Efterlyst portrays crime and the image of crime the statistics gives.

Ett stort evenemang - En liten stad : Synen på Vätternrundan genom fem representanter

Vätternrundan is an annual sporting event that takes place in the Swedish town Motala since 1966. It is one of the world largest recreational bicycle rides and attracts over 20 000 participants each year. This study focuses on event effects and how an event can be of value within the principles of place marketing. Within this study five representatives were interviewed with semi-structured interviews.The results show that the representatives describe Vätternrundan as a positive event which mostly generates positive effects for the city itself and for the people living and working there. The effects consist of the events ability to create awareness of the place, the possibility to extend the tourism season and several social effects like solidarity and interaction.The result also shows that Vätternrundan is a well-known brand and because of this it can be used as an advantage in place marketing.

Majsensilage i Sverige

Maize for silage has been used as fodder in different parts of the world for a long time and has recently become more common also in Sweden. Our cold climate has been a problem as maize is very sensitive to low temperatures and frost. With new varieties and better techniques for cultivation it is now possible to grow maize in the southern and middle parts of Sweden. As for the north of Sweden the length of the cultivation season is a limiting factor as there are too few days with temperatures of over +10 ºC. Maize is well suited for silage making but oxygen-free conditions are required.

Registrering och avel för brunstvisningsförmåga hos mjölkkor

Dairy farmers using artificial insemination (AI) are dependent on effective oestrus detection. In Sweden, AI is used for a majority of all dairy cows and oestrus synchronisation with hormones is not allowed. There are reports of declining ability to express oestrus with higher levels of milk production. This makes oestrus detection more difficult. Several aids for oestrus detection have been developed, for instance pedometers and mounting detectors.

Orsaker till kolik hos häst

The aim of this work was to investigate possible risk factors for colic in horses, and to describe what horse owners can do to prevent this condition. The gastrointestinal system of the horse is constructed for continuous high fibre consumption for a period up to eighteen hours a day. Under those conditions, the continuous flow of digesta stimulates gut motility so that the intestines move constantly. When the diet is changed rapidly and the horse is being fed high rations of concentrates each day, the risk of getting colic is higher compared to when consuming less concentrates and giving the horse a stable diet. Lack or absence of access to water and restricted allowance to move freely every day increases the risk of colic. Changed management practices and decreased activity contributes to increased risks, as well as other critical risk factors such as breed, season and age combined with rapidly changed management. More knowledge and education is required of the horse owners about feed requirements in the horse, management routines and rapidly changed activity..

Cultivation of Chlorella vulgaris in nutrient solution from greenhouse tomato production : a possibility to reduce nutrient levels and produce commercially interesting metabolites

The idea of using algae in different areas and exploring its possibilities is nothing new. Already in the early 1950s microalgae was explored as a possible food resource because of its high protein content. Lately there has been an increased interest in its potential for industrial use. Wastewater treatment is a possible use of algae since the algae grow well on the nutrients present in the water. This offers the possibility to grow algae for nutrient reduction and use the biomass for energy or animal feed since many alga species has a good nutritional value. Approximately 800-1000 m3 water is applied per 1000 m2 of greenhouse area during one season in a tomato production.

?Kryddan i maten? : Redesign av en kokbok

The purpose of this project has been to redesign an already existing cook-book. The title of the book (directly translated), ?Season in food ? the year around with herbs and spices?, contains what the headline imposes: spices, herbs and food. But when the author tries to entwine these parts and communicate it to the reader it is not working all to well due to a poor and inconsistent graphic design.I have followed the theories and values of information design when I redesigned the book layout with the intent to simplify the communication between author and reader. In the progress to make a complete dummie of the book I did multiple literature studies, book analysis, tests and a vast number of drafts.In this report I will describe the whole process from start to finish.

Mätegenskaper för fruktsamhet och modersegenskaper i fåraveln :

The aim of this literature review was to suggest suitable index traits to use in the Swedish Sheep Recording Scheme for fertility and maternal traits. Since fertility and some of the maternal traits are not normally distributed advanced methodology is needed to calculate genetic parameters. Breeding is a tool to improve the economy of the farm and for the selection of breeders estimated breeding values (EBV) for important traits are of high value. In sheep breeding both lambs born and lambs weaned should be taken into consideration as well as the ewe?s maternal ability, which includes lambing ease, lamb survival, ewe behaviour as mother and the early growth of the lambs.

Vallfoderproduktion i norrländskt klimat till högpresterande hästar :

High-performance equine athletes have an energy requirement that often reaches twice the maintenance requirement. Horses are grazers and adapted to a grass diet, and diets high in grains and concentrates are associated with digestive upsets and behavioural disorders. It could therefore be of interest if the energy requirement of a high-performing horse could be met by forage. It is important that the forage have a high concentration of energy so that the horse is able to consume the whole amount of energy needed from the forage without exceeding the maximum voluntary intake. The purpose of this literature study was to investigate if the energy demand of a high-performance horse can be covered by forage produced under Northern Swedish climate conditions.
