Effect of plant maturity at harvest of haylage on digestibility and faecal particle size in horses fed forage-dominated diets
Time of harvest affects nutritional value and digestibility of haylage since plants are in different developmental stages. The aim of this study was to examine the effect of plant maturity of haylage cut in June, July and August on digestibility and faecal particle size in horses.Forage and faecal samples used for the analysis of apparent dry matter digestibility (DMd) and particle size distribution in faeces were from a feed-study performed in the autumn of 2009. Twelve horses were used in the study, divided into three groups in a change-over experiment. Each group was fed haylage harvested in June, July or August during three periods. Faecal grab samples were taken from each horse and pooled so that one sample represented one horse during one period.
Förbränning av pellets framställda av defibrerad granråvara :
Fuel pellets are in Sweden mainly produced from sawdust and cutter shavings. Before the pelletising process the raw material is dried to attain consistent moisture content and ground up in a hammer mill. In the densification process (pelletising) the ground material is forced through holes in a rotating die. This heats up the wood particles which cause them to soften and self bond. After the process the pellets are cooled, sieved and bagged.
The milling process creates a wide range of particle sizes.
Siktning som saneringsmetod för metallförorenad mark
Toxic metals contaminate soil worldwide and thus serve as sever environmental threat. Therefore the purposes of this study were to investigate in which soil fractions that different heavy metals (Fe, As, Cu, Zn and Pb) could be found in contaminated soils and if it is possible to use sieving as a method for decontamination. Soil samples were collected from three different locations, the Nasa silver mine, the Blaiken-mine and Svalget environmental station. The samples were oven dried and later on sieved into six different fractions 8mm, 4 mm, 0.5 mm, 0.250mm, 0.063 mm and <0.063 mm. The fractions 4 mm, 0.5 mm and <0.063 mm from each location were analyzed in an x-ray fluorescence detector.
Jämförelse av icke-kryptografiska hashfunktionerför användning i hashtabeller
This report examines some common or otherwise interestingnon-cryptographic hash functions with respect to the number of collisions when used in hash tables for different types of hashkeys. The report answers which of the examined hash functions can be seen as the best performing for the chosen hashkeys. To compare the different hash functions, an experiment which studies avalanche effect behaviour is carried out. The experiments also calculate the fraction of colliding hashkeys, and the distribution of hashkeys in hash tables is studied using Karl Pearson?schi-squared test.
Composition of fractions from air-classified wheat flour
The unique ability of wheat to produce leavened bread is mainly due to the gluten proteins present. As consumers are more and more attracted to bread with high fibre content the use of wheat gluten will also increase in order to obtain bread with good volume and appetizing characteristics. Air-classification is a technological method used to separate particles by size and shape by means of air-streams into two fractions, fine and coarse. When used on wheat flour it is known to alter the flour composition in the fractions obtained compared to the original flour. This method is not widely used in the milling industry but could possibly be of interest if protein rich fractions with favorable protein quality can be produced.
How streaming media can be used in commercial mass
distribution
Mass distribution with techniques as multicast and peer-to-peer are becoming increasingly important in the Internet. Today the distribution of sound and video over Internet, so called streaming media, is static due to the unicast method. This results in a linear increase of distribution costs and therefore no conditions for commercial scalability. This thesis describes why multicast may be the only scalable alternative for commercial mass distribution of streaming media over Internet. Mass distribution through peer-to-peer technology promises a lot but is fronting a couple of great challenges, for example asymmetric bandwidth, locality and legalization.
Uppfångning och kvarhållning av 134Cs och 85Sr i olika växtutvecklingsstadier
Emissions of radionuclides to the atmosphere can lead to wet deposition on plants in the event of rainfall. An increased level of radioactivity in the plants may occur due to interception and retention of the radionuclides. If the content of the plants is above the threshold limit value, entire yields may have to be destroyed. In order to prevent contamination or decrease the content countermeasures can be taken. The impact of the
biomass, leaf area index (LAI) and growth stage of the plant on the interception and retention is important to know in order to decide which countermeasures to use.
Weather may also be an important factor.
In this work the interception and retention of 134Cs and 85Sr by spring wheat, ley and spring oil-seed rape was studied.
Tillbaka till framtiden - om svensk filmdistribution i den digitala eran
Why is the e-revolution of the Swedish film distribution lingering? In attempting to answer that question, this qualitative study depicts the distribution market of Swedish film and its actors. Thirteen interviews with representatives of the industry have been conducted in search of an understanding of the current situation. Two important conclusions are made. One is that the strong interdependency between the actors of film distribution is inhibiting the acting space of those who seek change.
Lättlösliga kolhydrater i vallfoder och i hästens grovtarm :
The purpose of this study was to investigate how the content of glucose, fructose, sucrose and fructan (WSC) varied in silage, haylage and hay harvested from the same field and at the same time of harvest. The study also investigated if differences in the WSC-fraction in the forages caused differences in composition of WSC in the colon of horses fed the forages. Hay, haylage and silage were harvested in the first week of June 2005 and stored for about nine months before feeding. Horses that were fistulated in right ventral colon and caecum were used, but only the colon fistula was used for sampling.
The fresh crop and the conserved hay, haylage and silage were analyzed for chemical composition and WSC-fraction.
Latitudinal patterns in body size of Roesel?s bush cricketMetrioptera roeselii within and outside the continuous area of its distribution
Over time, species colonize new areas naturally or through humans. The colonizers areoften few and founded populations represent only a fraction of the genetic diversityexisting in the original population. If the established population becomes isolated afterthe colonization event genetic diversity will remain low and if the population, in addition,remains small in size for an extended period this will lead to increased inbreeding andpossibly inbreeding depression. Metrioptera roeselii is a common species with awidespread distribution in continental Europe. During the last century, it has expanded tothe Scandinavian Peninsula which is separated from continental Europe by the Baltic Sea.My aim was to test the hypothesis that individuals in isolated populations in Scandinaviaincluding Denmark and the Baltic Sea islands are smaller than individuals in thecontinuous part of its distribution due to low genetic diversity and lacking incoming geneflow.

Matrismodellen vs Two-part regressionsmodeller - effekter på Region Skånes resursfördelning
An important task for Region Skåne is to allocate resources to the health care districts. From 1999 to 2002 Region Skåne used needs-based resource allocation as a model for allocating resources. In a needs-based resource allocation individuals with the same socioeconomic and demographic characteristics are assumed to have the same level of need and are therefore allocated the same amount of resources. During the period of needs-based resource allocation a matrix model was used as a method. In the matrix model individuals were divided into cells after each combination of the socioeconomic and demographic variables.
Majsensilage - partikelstorleksfördelning och hygienisk kvalité :
Fieldstudys on 22 farms (23 silos) to study relationships
between the actual particle size of the maize silage and the theoretical length of cut. The measure of theoretical length of cut were stated by the farmers and not measured by us.
Particle size of maize silage was determined using the New Penn State Forage Particle
Separator. SLU Skara made a special sieve for us, that had larger holes than de original
sieves. The samples were shaken after instructions and then the
material was weighted. We have also been taking out samples for microbiological
analyses from the silos on 13 of the farms.
Utveckling av intranet på Pharmacia & Upjohn, Helsingborg : Informationsspridning med hjälp av WWW teknologi
The purpose of this paper is to describe how the workgroup and I developed and constructed an Intranet at Pharmacia & Upjohn, Helsingborg. The Intranet was constructed by the help of WWW-technique. The intention was to increase and improve the distribution of information in the large company. Some of the employees were interviewed and asked what they could gain by using the Intranet for information distribution instead of the usual papers. They also got a chance to tell us what they thought about the whole idea with the Intranet.
Sånger från graven: En kartläggning av krafterna som hämnar den digitala revolutionen inom svensk musikdistribution
Songs from the Crypt: Mapping the Forces that Hinder the Digital Revolution of Music Distribution This paper seeks an explanation to the low market share growth of the commercial digital music distribution in Sweden. The analysis identifies a spectrum of obstacles that hinder the digital distribution technology from becoming the main form of music distribution in Sweden. These obstacles make the digital music distribution less favourable in comparison with physical distribution from the consumer?s point of view. The authors suggest that in order for the digital distribution of music to become competitive the digital product would either have to be developed further to offer more customer value or the so called a là carte retail model would have to be replaced by a subscription-based distribution model.
