Utvärdering av en ny selektionsmetod för hingstsperma : med avseende på membranintegriteten och membranstabiliteten

Today, equine breeding is based on performance and conformation, resulting in a vast variation in fertility among different horses, with noticeable economic losses as a consequence. The horse breeding industry is therefore in need of methods that diagnose the spermatozoa concerning their quality and provide the best sperm for AI. The commonly used selection methods for sperm today are: centrifugation, where extender is added, the sample is centrifuged and then resuspended; swim-up self-migration; adherence separation; and density gradient centrifugation. However, none of these methods are in used routinely in practice before inseminating mares with fresh or cooled semen. The aim of this study was to evaluate a new selection method, Single Layer Centrifugation (SLC), and its effect on sperm viability. The viability was analyzed with regard to membrane integrity and membrane stability of ejaculated spermatozoa.

Grundvattenmodellering i Badelundaåsen

Over an extended period of time there have been plans to establish a shared facility in Lennheden to extract groundwater from the Badelunda esker to provide drinking water for the cities of Borlänge and Falun. The city of Falun is dissatisfied with the quality of its drinking water and the city of Borlänge is concerned about the risk of contamination of its existing groundwater supply at its current location. To provide a basis for a decision on this issue, the company Midvatten AB has been commissioned to perform hydrogeological investigations in the area of Lennheden.The purpose of this thesis is to design a functional groundwater model of the area between Lennheden, place of planned extraction, and Övre Tjärna, place of existing extraction, to get a better understanding of the groundwater situation in the area. A groundwater model enables simulations of different scenarios in risk assessment and contaminant transport. The aim of the thesis is that the model can be used as an aid in Midvatten?s investigations in Lennheden and that it also can be used in future projects in the area.The model has been made in Processing Modflow 5.3 and encompasses an area of 19,5 × 11 km along the Badelunda esker and the river Dalälven between Djurmo and Frostbrunnsdalen.

HipHopvideor - Från idé till färdig produkt

Vi, Anna Nilsson och Jeanette Svensson, valde att producera musikvideos under vårat kandidatarbete på Blekinge tekniska högskola. Detta eftersom vi båda har ett stort intresse till musik och rörlig bild. Vi valde att göra två stycken för att lära oss produktionens process grundligt och för att nu kunna jämför de båda och av detta ta lärdom. Den ena musikvideon gjorde vi till en skånsk duett som heter KC och den andra till Advance Patrol. Båda låtarna är inom genren hiphop. Vårt mål med projektet var att skapa två videos som inte följde den generella mallen för hiphop-videos.

Riskbedömning vid Saltvikens kopparverk

AbstractAt Saltvikens copperindustry, which is located in the municipality of Oskarshamn, copper was refined from sulphiteore some hundred years ago. The ore underwent several steps in the process before the final product was received. These steps all had an influence on the environment through discharge of heavy metals. The area where the copper industry was located is today considered to be of specific national interest due to its valuable nature and cultural values, as well as its value for recreational outdoor activities. Therefore, it is important to determine the present level of contamination and if any transport of contaminants have occurred, and to identify the risks that are associated with the site both at present and in a longer time perspective.Thirtynine soil samples and 16 sediment samples have been analyzed.

Effekten på nedbrytningen av rötter vid tillförsel av ammonium sulfat i en granskog i sydvästra Sverige

Decomposition of organic matter is a critical process in the ecosystem, which involves many essential biotic and physical parts. Decomposition is therefore an important process both above and below ground. The rate of decomposition is dependent of many environmental factors for example: pH, moisture and supply of oxygen. The decomposition can therefore be affected by large scaled environmental influences, such as acidification and climatic changes. The root litter in the forest is in different ways affected by acidification, liming and manuering.

Vindfällning, tillväxt och plantuppslag i en 13-årig granskärm i Medelpad :

The interest for alternative forest regeneration methods increased significantly during the 1990´s after 50 years dominance of the clear-cutting system (Holgén & Hånell 2000). One reason for this was that clear-cutting was being more and more questioned by different envi-ronmental organizations and because the forest sector for economical reasons wanted to find cheaper ways to regenerate forests. In the beginning of the 1990´s two shelterwood experi-ments were established in a joint effort by Svenska Cellulosa Aktiebolaget (SCA) and the Dept of Silviculture, Swedish University of Agricultural Sciences (SLU). The experiments include various forms of cutting and shelterwood densities and represent productive spruce forests in central and north Sweden (Roggsjön in the province of Medelpad and Skikkis-jöberg in the province of Västerbotten, respectively ). The experiment next to Roggsjön has been reported earlier in three MSc theses, and is also the focus of this thesis.

Organisationsstruktur och internkommunikation efter en omorganisation : En fallstudie om Karlstads universitet

This is a case study which investigated the perceived consequences of the organizational change that was implemented in January 2013 at Karlstad University. The study aimed to explore the experiences of the employees concerning the changes in organizational structure and internal communication. This was done through a set of eight individual standardized qualitative interviews with members from different departments. A lot of effort and thought was given to the ethical implications and to create a comfortable and open climate during the actual interviews to ensure that the respondents felt free to speak openly and honestly about their personal opinions and experiences.It is evident that the overall vision was ambitious; aiming to create a more effective organization through cutting off excessive administrative personnel and streamlining decision paths. However according to the opinions of the respondents it was clear that the result was far from the desired goal.

Löslighet och metylering av kvicksilver i en förorenad sjö (Ala-Lombolo) i Kiruna kommun :

Transformation of inorganic mercury (Hg) to methyl mercury (MeHg) is a biotic process that is proposed to be conducted primarily by sulphate reducing bacteria (SRB). The formation of MeHg is of great interest because it is the mercury species that biomagnifies to the greatest extent in the aquatic food webs; about 90 % of all Hg in fish is MeHg. Our understanding of factors involved in the production of MeHg is very important for making a reliable risk assessment. The purposes of this study were to investigate the different factors that control the solubility of Hg and the production of MeHg in a contaminated lake sediment. The lake Ala-Lombolo, Kiruna municipality, is well-known to be contaminated by mercury from different sources. Sediment cores were sampled at three different locations (N, SW and SE) in the lake and divided in three different Layers; 0-5, 5-10 and 10-15 cm.

Do 25 years old skid tracks restrict growth and survival? : a study on growth conditions for the planted regeneration in a rainforest rehabilitation project

The rainforests of the world are important not only to the countries in which they grow but to the world as a whole. They influence oxygen and water circulation as well as carbon sequestration which in turn affect global radiation and global warming. The forest also have great value and in Malaysia as in many other tropical countries large volumes are harvested which leaves great areas of degraded forest with little growth and biological diversity. Due to their low financial value these forests are often transformed and used for other purposes than forestry such as oil palm plantations. The trees are often transported out of the forest using large bulldozers. They are heavy which causes compaction of the forest floor and during transport the top soil Layers are moved to improve mobility.

Packaging Design as a Brand-building Tool

The topic of our thesis is Packaging Design as a Brand Building Tool and we are presenting the Scandinavian perspective. We found the topic interesting because, from a theoretical point of view, we identified a scarcity in research focusing on packaging design as a brand management tool, and from a practical point of view, we found out that businesses use packaging design at different levels in their communication efforts. Thus we wanted to provide both academia and business world with a clear picture to what extent and how businesses use packaging design in their brand-building process. Therefore the aim of our thesis is to provide practitioners and academicians alike with a better understanding of how packaging design can be used to create strong brands in the FMCG sector in the Scandinavian market. To reach the stated aim first we provided a solid theoretical background of packaging, its elements and its role in the marketing mix.

Landskapsurbanism i en Post-Industriell kontext

I examensarbetet ?Landskapsurbanism i en Post-Industriell kontext? diskuteras den relativt nya diskursen kring ?Landscape Urbanism? eller ?landskapsurbanism?. Arbetet fokuserar på platser som har övergivits av industrin, i skenet av den post-industriella utvecklingen. Huvudmålet med studierna av ämnet är att belysa ett antal ?landskapsurbanistiska metoder? och sedan tillämpa dessa på min plats: den gamla Cementafabriken på Övägen i Limhamn, Malmö.Den största inspirationskällan i detta är den amerikanske landskapsarkitekten James Corner´s teorier, och de metoder som utövas av hans landskapsarkitekturbyrå; ?Field Operations? i New York.Eftersom ämnet täcker in väldigt många aspekter och problemställningar rörande samtida urban planering och design, har jag i enlighet med Corner delat in min text under fyra rubriker:- Processes over time- The Staging of surfaces- The Operational or Working method- The ImaginaryDet gamla cementfabriksområdet har förvärvats av byggbolaget NCC, och kommer inom en snar framtid att bebyggas med bostäder.

Effekter av gödsling i äldre tallbestånd på renbetesväxter i fält- och bottenskikt :

Reindeer husbandry and Forestry are both area related industries and will in big extent use the same lands. Conflicts often arise because of that the industries have different interests. Many of the activities done by the forestry influences the reindeer husbandry in an undesirable way, simultaneously as the reindeer husbandry activities can have negative consequences for the forestry. One such forestry activity is fertilization. It was during the 1960´s forest fertilization began to be practiced and the reason was that the increase in growth that the fertilization gave could be able to cover for the future shortage in wood many feared. During the 1970´s when the fertilizing activities were most intensive about 200 000 ha was fertilized annually.
