Är den starkt växande vildsvinspopulationen ett hot mot tjäderns reden?
This case study is based on a previous documented method of manufacturing artificial nest containing pre-colored hen eggs. This method is going to be used to find, if the wild boar population, which is growing in number, is a threat to the capercaillie population. In comparison to the wild boar population, the capercaillie population is diminishing in different parts of Sweden. In order to find out if they are affect by each other, the case study was carried out during the months of April to May 2009. 100 artificial nests were placed out on various locations on the Södertuna estate just in the outskirts of Gnesta. The unique aspect of this study is that a fenced environment to keep out wild animals is used to conduct this study, which has been previously known to be free from wild boar, but the area outside has sittings of wild boar. So to fully understand how this affects the capercaillie population, 50 of the nests were placed outside the fence area, while the other 50 nests were placed inside the fenced area. The sites were visited on two separate occasions, and were noted of the changes inside and outside the fenced compounds.
Produktionsvåtmarker mot övergödning
In ambition to produce more and better harvests, artificial fertilizers are used to produce a better growth of crops in the agriculture landscape. This contributes to leakage of nutrients. Our forests also exhibit a leakage of nutrients. Air pollution contributes to more nutrients. High precipitation with high water flows as a consequence seems currently to occur more frequently in the county of Halland.
Bolag i skatteparadis : Affärsmässigt motiverad verksamhet eller skatteflykt i form av konstlade upplägg
EU law is superior to Swedish domestic law, and it is on Sweden's responsibility to implement the COJ judgments so that it becomes compatible with EU law. The advantage of the Union being superior is the internal market given the member states.However, problems arise when the Swedish legislature goes further in its interpretation of EU law. Restrictions can be imposed but it must be considered to be strongly motivated so the restriction outweighs the need to maintain the freedoms granted by EU law. In Cadbury Schweppes, the court states that restrictions on freedom of establishment may be done to counter artificial arrangements whose sole purpose is to evade the national tax. Its further stated that an artificial arrangement does not exist in those cases there is a real business, even through the establishment in the low-taxing country is economically justified. The Swedish CFC rules states that the general rule is that if an establishment in a country within the EEA, which have lower corporate tax than 55% of the Swedish tax, the shareholder of this company is taxed on its current share in Sweden. The outcome of Cadbury Schweppes has not been made into a general rule, it became the exception. In addition to that in Sweden it is presumed that the company is an artificial arrangement that expressly are prohibited by the EUD, as well been implemented to supplement the rule, where the Swedish legislature changes the meaning of the term granted by the appeal. The Swedish legislature has amended the original economically motivated establishment, to be commercially motivated. The term is undefined, but applicable elsewhere in the Incometaxlaw and from this one can find that, for an establishment to be considered as commercially motivated the decisions to establish should be taken to promote normal profit-making enterprises based upon commercially motivated decisions..
Jämförelse mellan neurala nätverk baserad AI och state-of-the-art AI i racing spel
Denna rapport jämför prestandan mellan state-of-the-art AI-botar i racing
spelet TORCS och en AI-bot
som kör med hjälp av ett artificiellt neuralt nätverk (ANN-bot). ANN-boten, som
implementerades som
en del av arbetet, använder en feedforward arkitektur och backpropagation för
inlärning. Ett separat
program som användes för att träna det neurala nätverket med träningdata som
spelats in från TORCS
implementerades också. Som state-of-the-art AI-botar användes AI-botar som har
använts i en tävling.
De fyra AI-botarna testades på åtta olika banor och data om hur lång tid varje
varv tog och hur snabbt
AI-botarna körde sparades och sammanställdes. Resultaten visar att på banorna
som ANN-boten klarar
av att köra runt så är ANN-boten snabbare än en den långsamaste
state-of-the-art boten, men ANNboten
klara inte av majoriteten av banorna som den testades på.
Comparison of two methods for evolving recurrent artificial neural networks for
n this dissertation a comparison of two evolutionary methods for evolving ANNs for robot control is made. The methods compared are SANE with enforced sub-population and delta-coding, and marker-based encoding. In an attempt to speed up evolution, marker-based encoding is extended with delta-coding. The task selected for comparison is the hunter-prey task. This task requires the robot controller to posess some form of memory as the prey can move out of sensor range.
Pig behaviour during crowding : a study in organic and conventional herds
Rearing in organic pig production differs from conventional rearing; pigs have outdoor access and larger space allowances. Regardless of production system all pigs are transported before slaughter and during transport pigs are crowded together in a new environment and in a space smaller than they are used to. As pigs in organic herds are reared at even larger space allowances than conventional pigs, such crowding could possibly have a stronger impact on pig behaviour and well-being. Six pig producing herds, three conventional and three organic, were visited and pigs from each herd were enclosed during 12 minutes in a test area corresponding to the crowding on a transport vehicle. During the crowding, pigs? behaviour was observed, before and after enclosure in the test area skin lesion scores were recorded, and also measures of heart girth (for weight estimation) was done.
Samrådsunderlag för Lysekilsprojektet : Forskning och utveckling av vågkraft
The aim of this research is to find out what environmental impact a wave power park has on the Swedish west coast by creating a consultation paper (?Samrådsunderlag?) for the Lysekilproject at Uppsala University. To highlight the complexity of the problem a system analytic approach was used and illustrated by a Causal Loop Diagram.The overall assessment of the Lysekilprojects wave power park at the Swedish west coast is that it will have a low impact on the environment. This is due to the relative small size of the wave power park and some technical solutions made with the environmental aspect in mind. Artificial reefs and a sanctuary for marine species are effects created by the wave power park and in the longer term the impact will give access to an untapped source of renewable energy, wave energy.
Barnaga - unga vuxnas attityder
The purpose of this study is to examine young adults', 18-19 years old, attitudes towards corporal punishment and with the help of social constructionism, grid-group theory and relevant concepts analyze the results and compare it with previous research. The research questions introduce various factors such as gender, origin and personal experiences of corporal punishment that may affect the attitudes. In order to fulfill the purpose and answer the research questions, a quantitative research method has been selected. There was 118 participants in the survey. The study was conducted by means of surveys in high schools in Örebro. Social constructionism made us realize how the community, perceptions and expectations might influence attitudes. Grid-group theory gave us an insight into how different family structures may explain why attitudes toward corporal punishment of children differ between individuals.
Nursing technique and growth environment of Rabbit fish (Siganus guttatus) in the area of Tam Giang lagoon, Thua Thien Hue
SummaryIn the area to the east of Hue city, in Vietnam, lays Tam Giang lagoon, one of Asia's largest lagoons, with an area of 22,000 hectares. This lagoon is suitable for aquaculture. One reason for this is because the salinity differs from sweet to salty in different parts of the lagoon. The Vietnamese Government advocates an increase in environmentally-friendly aquaculture and the fish Siganus guttatus (Rabbit fish) is a candidate for this. This fish eats mainly algae and can be cultivated in a polyculture.
Hjälptyglars inverkan på hästen
The horse has been domesticated for several thousand years. It has gone from being used primarily for food and transportation, to become one of the most popular pets in Sweden. With over 150,000 practitioners, horseback riding is one of the biggest sports in Sweden and there is a variety of specializations to choose from. One orientation is western riding which is a broad sport with several disciplines where most originate in cattle work and other ranch tasks. Western riding is a growing sport in Sweden with an increasing number of practitioners and with many different organizations and associations, it is important that the correct knowledge of the equipment used is disseminated.
Artificial aids are available in a variety of designs and the most common variants used by western riders in Sweden is draw reins or some forms of martingale.
Prosamodernism, form och genusdebatt : En komparativ form- och receptionsstudie av Karin Boyes Astarte och Rosa Chacels Estación, ida y vuelta
The aim of this study is to compare the modernist novels Astarte (1931) by the Swedish writer Karin Boye with Estación, Ida y vuelta (1930) by the Spanish author Rosa Chacel and the reception of these literary works in contemporary academic research. The theoretical ground of the study consists of feminist and critical theory, with traits of discourse analysis.Astarte and Estación were in large part forgotten and ignored by the Western Canon of literature during most of the 20th century, but have lately gained more attention as important modernist novels by researchers (from the feminist, poststructuralist or hermeneutic theoretical fields) who primarily examine the experimental forms figured by the texts in relation to the deconstruction and shattering of human homogenous ?essence?.The results found in the study show that the literary forms of both novels can be associated with a kind of illusion rapture, which relate to the modernist inclination to what Frederic Jameson calls artificial narrative; a form technique that points back at itself to emphasize its own characteristic of being a constructed and subjective illustration of reality. The contemporary interest in these artificial literary forms expressed by Astarte and Estación is therefore probably a consequence of the vibrant academic debates carried out during later decades concerning the conception of human gender and identity as construction and performance. .
Interdependence between seed age and aerated steam treatment intensities
Aerated steam treatment is a modern and environmental friendly method for seed borne fungus sanitation, mainly used on cereals. The method involves exposure to heat and high humidity, factors which are known to induce a fast ageing of seeds, thus resulting in reduced storability. This thesis clarifies the interdependence between seed age and the aerated steam treatment intensities.
Two studies were carried out in this thesis. In the first study the storage longevity of seeds treated with aerated steam was examined. The second study investigated the shelf-life of the pre-tests used to determine the aerated steam treatment tolerance of a seed lot, by testing the treatment tolerance of seeds aged prior to the treatment.
Vaccinering mot galtlukt ? ett alternativ till obedövad kirurgisk kastrering av smågris
In 2012, about 1.3 million boars were surgically castrated, most of them without anaesthesia. Castration is performed to avoid the occurrence of boar taint and aggressive and sexual behaviour. There is a growing concern about the welfare of the piglets and the Swedish Board of Agriculture is working to find efficient and functional alternatives to castration without anaesthesia. The aim of this study was to obtain an overall picture of the latest research about the alternatives to castration without anaesthesia, with focus on vaccination against boar taint, and how they affect the welfare of the pigs.
The alternative methods that are available today are surgical castration with anaesthesia and/or analgesia, rearing entire males and vaccination against boar taint.

Nötköttsproduktion i Västerbotten
Beef production in Sweden has traditionally been about rearing of dairy calves to slaughter. With reduced number of dairy cows and accordingly less dairy calves for slaughter, there has been a need for new forms of beef production in Sweden. In Västerbotten there are good conditions for beef production with a high feeding level of roughage due to favourable climate. The aim of this thesis is to, through interviews with ten farmers with beef production in Västerbotten, study what and with how much they feed their animals and link the results to production level. The thesis begins with a literature review where the general feeding standards and feeding recommendations for beef cows and growing cattle are examined.
