Denna litteraturstudie har utförts med syftet att redogöra för hur husdjursavel kan användas för att minska den negativa miljöpåverkan från animalieproduktion. Animalieproduktion påverkar miljön negativt genom husdjurens utsläpp av växthusgaser, främst metangas. Litteraturstudien behandlar huvudsakligen idisslare eftersom den största delen av de totala metanutsläppen, från husdjur, härstammar från dem. Metangas bildas under den mikrobiella fermenteringen som sker i våmmen hos idisslare. Fermentering av foder med hög smältbarhet resulterar i mindre metanbildning jämfört med foder med låg smältbarhet.

In this paper, I have proposed a way of interpreting the philosophical subject of the Discours de la méthode that has remained relatively unexplored by contemporary commentators. By investigating the subjectivity that is expressed through Descartes? use of architectural metaphors, I laid bare some of the difficulties inherent in its discursive structure, as well as suggesting that the cogito in fact repeats and inscribes itself into this structure. In this context, the metaphor of the road (or travel) takes a supplementary role in relation to the architectural metaphor, marking the very conditions of existence of the architectonic subject. The subject, in order that it may establish itself as ?pure? and ?independent? thought, is dependent on a certain ?forgetfullness?; that is, only by forgetting its constitutive dependence on the diversity and historicity that is signified by the metaphor of travel, can it establish itself as its own source.

Thoroughbred racehorses have suffered from exercise-induced haemorrhage for over 300 years. Almost all competing horses develop exercise-induced pulmonary haemorrhage (EIPH) at some point but most horses don?t suffer from reduced competing capacity due to the disease. The cause of the exercise-induced haemorrhage is unknown. The most believed theory today is that EIPH is induced by pulmonary stress failure caused by pressure over 100 mmHg in the pulmonary arteries during exercise.

It today's global world we live in the media have started to examine businesses more and more. In addition consumers are expecting more from products, because they are well informed. This means that companies need to market themselves effectively, to convince and get across their message to their customers. Marketing is an extensive process in which different factors must be taken into account. A company must know what the coustomer needs in order to get through to them.

Among researchers it has been established since decades that humans and animals have an internal biological clock that controls certain physiological mechanisms. One example regarding humans is the impairment of lung function during the night, causing the phenomenon ?nocturnal asthma? among asthmatics. Only a few studies concerning respiratory circadian rhythm in horses have been done previously and they showed a daily variation in horses with a chronic or an acute respiratory disease. The technique used in those studies was the conventional technique, which is invasive and less sensitive than the technique used in this study.

The urban heat island is an area restricted to a city center where the temperatureis higher than its surrounding environment. The greatest temperature difference isfound at night when the weather is calm and the sky is clear of clouds. There are twomajor causes behind this phenomena and the first one is the use of energy forheating of houses. The heat leaks through the walls of the buildings and warms upthe surrounding mass of air. The second one is the use of building material whichstore the suns radiation on daytime and releases the heat during night.

Med utgångspunkt att självskadebeteende är ett internaliserat problem är syftet med studien att i en ungdomspopulation undersöka om självskadebeteende även är länkat till externaliserade problem. Vi undersöker även om självskadebeteende hänger samman med att i olika miljöer utsättas och utsätta andra för negativa beteenden. Studien använder redan insamlade data i forskningsprojekt kallat - ?Sju Skolor?: Center for Developmental Research (CDR). Data samlades in från 1478 högstadieelever.

The different characteristics of many food products, such as aroma and texture, changes during storage time and become undesirable. The reason is instabilities within the product which become prominent as the product ages. These changes in characteristics are quality losses caused by changes in the product?s intrinsic and extrinsic environment. The stability in UHT-milk and beverages similar to it have been studied in the past decades and a certain focus have been on age gelation which is a common defect in these type of products.

Studiens syfte är att studera vilken bild av muslimer som förmedlas i svensk tidningsmedia veckan efter terrorattacken mot World Trade Center i New York den 11 september 2001. Undersökningen tar sin teoretiska utgångspunkt i postkolonial teori och Saids ?orientalism?-begrepp. Jag har valt att använda mig av en riktad kvalitativ innehållsanalys för att undersöka vad källmaterialet förmedlar och har utifrån innehållet skapat kategorier som ska tydliggöra detta. Slutresultaten visar att den bild som tidningarna förmedlade av muslimer efter terrordådet den 11 september 2001 var präglad av stereotyper om Orienten, där muslimer bland annat beskrivs som känslostyrda, omoderna och religiösa.

The aim of this project was to develop educational resources concerning bioenergy and sustainability. The initial purpose was to produce two sets of material: one suitable for children in their first years of Swedish compulsory school, and one designed for upper secondary students. In the report, however, the possibilities are discussed for this material to be used with even wider audiences.In the first phase of the process, literature (books, reports etc.) with relevance to bioenergy, sustainability and theories of learning were studied. This insight, along with the appropriate course curriculums, was used in the development stage to produce learning material for the targeted audiences. The development was followed by tests and evaluations carried out with high school students, upon which an analytical discussion is held regarding the consequences and possibilities that the results of this project pose.The content of the learning material is based on the curriculum and course requirements provided by Skolverket (The Swedish National Agency for Education) for lower elementary and high school students.

Bosch Rexroth Mellansel är en tillverkare utav hydrauliska drivsystem för industriella applikationer. En del av denna lösning är de så kallade Hägglunds-motorerna. Fem motorfamiljer tillverkas i olika storlek och för olika applikationer. Syftet med detta projekt var att undersöka fyra frågeställningar angående tre sammankopplade steg i produktionen av dessa motorer. Dessa stegen var tvätt, montering och provning.

Livestock animals affect their environment in a number of different ways, mostly through grazing and trampling. This study focused on the effects of Gotland pony grazing on forest structure and diversity, and the impact on ground cover. To compare the fenced and grazed area with a reference area outside the enclosure a number of transects were used. The study showed that there was no significant difference in height structure and diversity between the compared sites; however, there were a significantly higher proportion of damaged trees inside the enclosure. The ground cover variables showed a higher amount of bare soil, plant litter and wood-rush (Luzula sp.) inside the enclosure whilst grass was more frequent in the reference area.

Today, digital technologies (DT) can be said to play an important role in the Swedish school system. The goal of this essay was to describe DT use by school leaders, in relation to their views on schools? goals and visions, and teachers? and students? use of DTs. Semi-structured interviews were conducted with five school leaders of secondary schools in Umeå municipality, Sweden. The results show that school leaders? use of DTs center on three key tasks: communication, information and administration.

Ossification of the collateral cartilages of the distal phalanx has been studied primarily in cold blooded horses. The clinical relevance of this condition is unknown. Despite this fact, since 1939, all Swedish Ardenner stallions have had to be classified as being free from this ossification to be approved for breeding. Initially, palpation was used as a diagnostic method, but since 1982 radiology has been the only method used. The aim of this study was to assess the outcome of 68 years of breeding program. Dorsopalmar radiographs were taken of the front feet of 58 Ardenners (30 mares, 8 geldings and 20 stallions) and the ossification of the collateral cartilages was evaluated and graded according to three different scales; - Ruohoniemi (grade 0-5), - Swedish University of Agricultural Science (grade 0-3), - and a new scale (grade 0-3), developed for this study.
