Biomassauttag vid delkvistat sortiment i klen gallring
The purpose of this study was to estimate the removal of biomass in connection with thinning operations in young stands that are dominated by small diameter trees. The economy of such operations depends on the products generated as well as the performance of the harvesting systems. Conversion tables designed to predict the outcome based on harvesting method was another goal of this study. Removal of biomass affects the nutrient composition of the site. Therefore it is a purpose that this study will provide researchers with some variables that can be utilized when studying this aspect.
Trees were harvested and divided into bunches based on diameter.
Utvärdering av förbättrad metod för objektiv kvalitetsbedömning av spermiemotilitet hos hingst :
In this trial we used QualispermTM as an objective method of measuring stallion semen.
Samples of semen were analyzed before and after centrifugation. Motility and concentration
were statistically analyzed. During the trial all the objective mesaurments were compared to a
subjective method.
The advantages of QualispermTM compared to older CASA- systems is it´s ability of
measuring a greater amount of spermatozoa while it also grades them into different
subpopulations. These subpopulations have different qualities that decides their capacity of
fertilization.
The results showed that this objective method might be used practically. Although, there are
still some disadvantages, such as high costs and the necessarity of accurat training of the
handler.
If it´s possible to prove further relevant results that also are statistically correct, this could
prove the usefulness of QualispermTM as an objective measurment method in the daily work
at gestuts and stallion stations, thus giving the staff a reliable instrument in assisting the work
for an improved horse breeding in Sweden, improving both in quality and economically..
Förtätning av film till stillbild
During this project a photographer and an illustrator have explored if a single image can communicate a bigger whole, in this case a movie. By analysing five motion pictures with visual communication theories, semiotics and colour symbolism as tools, ten images was created. These images do not only consist of symbols, but also communicate the overall feeling and colour scheme of the movie.These images have been tested in interviews with six individuals, who, except for one, work with visual communication of some kind. They have studied the communication skills of the images from their own experiences.The result of the interviews showed that all images could not communicate a movie. One reason for this was that only a few of the test persons had seen two of the selected movies.
Skogsbrandens påverkan på död ved :
Fire is an important ecological factor, but its consumption of coarse woody debris, CWD, has hardly received any attention. In this study, I investigate the consumption in relation to the time of initial flame exposure and propensity for continued combustion of standing CWD of pine (Pinus sylvestris).
Two types of CWD were studied. Firstly, wood that had been dead for one to ten years. Secondly, wood that had been dead for several decades. In the burning experiments, logs of approx.
Bära lin - ett utforskande möte mellan tråd och visa
Simplicity, intimacy, freedom and one single threadcharacterize the knitting technique.In my project, I have studied ways of creating three-dimensional shape and structure using single threads and various knitting techniques. I applied my ideas in a collaboration with the singer Sofia Karlsson. The focus has been to design a portable object that can be used in pictures for the cover and promotion of her upcoming album.The material I studied, processed and used in creating the three-part object was linen. In the center stands a collar, that changes expression depending on how it is worn and which side is turned towards the outside. The collar interacts with a cylinder for her hands and a hairnet.
Utvärdering av näringsstatus inför återskapande av kalkkärr vid Hagebyhöga, Östergötland
Calcareous fens constitute a specific habitat which is uncommon in Europe and protected by the EU habitat directive due to its importance to several threatened species. Hagebyhöga in Östergötland is a calcareous fen habitat included in the Natura 2000 Networking Programme. Adjacent to the existing fen, a degraded fen area is situated. The area has been used for agriculture for several years but is now going to be restored to its former state by the county administrative board of Östergötland.When working with restoration of degraded fen areas it is important to aquire knowledge about the chemical soil conditions. Plant growth limited by phosphorus and low fertility are characteristic conditions for calcareous fens, whilst arable land usually is highly fertile and limited by nitrogen.The purpose of this study is to bring forth useful knowledge for restoring the degraded calcareous fen of Hagebyhöga.
Intervention med responsiva talakter inom AKK hos två deltagare med cerebral pares i Tanzania : en single subject design-studie
I många utvecklingsländer finns en begränsad tillgång på utvecklade AKK-system (Alant, 1999) och ofta även en okunskap kring möjligheterna att arbeta med kommunikationsproblem (Marshall, 1997). I föreliggande studie genomförs intervention i alternativ och kompletterande kommunikation (AKK) för två deltagare med cerebral pares på ett dagcenter i Kilimanjaroregionen, Tanzania. Syftet i föreliggande interventionsstudie är att genom intervention studera och utveckla de i mätsituationerna responsiva talakterna att påkalla uppmärksamhet för att inleda interaktion, acceptera och avfärda samt upprätthålla och avsluta interaktion. Detta sker med hjälp av begreppen ja och nej för att acceptera och avfärda, liksom mer och mindre för att upprätthålla och avsluta interaktion. Studien följer en single subjekt design och insatsen utgörs av två interventionsperioder, bestående av direkt intervention med deltagarna samt utbildning och fortlöpande handledning av personal.
Medarbetaravtal vid motorproduktionen i Skövde - inverkan på anställningsrätten, förläggning av arbetstiden, arbetstagarorganisationernas inflytande, samt arbetstagares arbetsskyldighet
White- and blue collar workers traditionally belong to different unions and, therefore, are covered by different collective agreements. Collective agreements for different employee categories create internal divisions, which mean that white collar workers are not obliged to do work that falls under a blue collar agreement and reversed. Historically the difference between white- and blue collar work has been fairly sharp and so has the difference between collective agreements. Due to the continuous development of technology white- and blue collar work within production has become less clear. This has resulted in an increasing amount of disagreements regarding what collective agreement should apply and whether the employee is obliged to perform different work tasks.
Passiva lantbrukare ? en effekt av EU:s jordbrukspolitik : en studie av ett antal faktorers påverkan på svenska passiva lantbrukares attityder till markanvändning och EU:s jordbrukspolitik
The problem with passive farmers has arised as an effect of the European Union´s common agricultural policy (CAP) and the decouplement from production-based payments. Payments to passive farmers contradict the purpose of the single payment scheme and constitute a great cost for the EU. The new contractual period after 2013 has given rise to discussions on the direction of the CAP with a purpose of increasing the efficiency of the single payment scheme, and reducing passive farming. The aim of the study is to increase the knowledge about a few factors? influence on passive farmers? attitudes towards land use and the CAP.
Lämpliga områden för vindkraftsetablering på land i Norrbottens län
Wind power is becoming an increasingly important source of energy. There are several national and international goals set to increase to amount of renewable energy, and in order to meet these goals, the wind power production plays an important part and the establishment of new wind power farms are required. The Swedish national project Riksintresse Vindbruk has appointed areas in Sweden suitable for wind power, mainly when looking at the physical wind conditions of the area. In this study, I aim to define suitable areas for wind power establishment in Norrbottens län. In order to reach this goal, a critical regional method was developed and completed using GIS.
Bandagering av framtass på hund och katt : en kvalitativ innehållsanalys
The field of veterinary nursing should be based upon research and proven experience. Few studies have been performed within the area of distal limb bandages. Therefore the aim of this study was to examine and describe how to place a distal fore limb bandage based on proven experience.
Data material was collected through four interviews with professional veterinary nurses, and then analyzed using a qualitative content analysis. In the analysis data material was transcribed and then divided into meaningful units that responded to the aim. The meaningful units were then condensed.

SyfteSyftet med denna studie har varit att undersöka vilka delar av upplevelsen som konsumenten får i en fysisk single brandbutik som bör efterliknas och lyftas in i samma företags digitala butik. Det har även varit att se hur väl företag förmedlar sina kärnvärden till sina konsumenter i den fysiska butiken. Slutligen har det undersökts vad som är viktigt när det kommer till egenskaper, funktioner och upplevelsen generellt för konsumenter när de handlar online.ProblemformuleringVad som gör denna studie speciellt intressant är att de single brandföretag jag har undersökt bedriver egen fysisk samt digital butik där de säljer sina produkter, men de har även återförsäljare som säljer samma produkter och blir på så sätt deras konkurrenter. Eftersom dessa single brandföretag har ett varumärke och kärnvärden som de måste leva upp till kan de inte sänka priserna på sina produkter på samma sätt som deras återförsäljare kan. Skulle då lösningen kunna vara att försöka lyfta in upplevelsen konsumenterna får i den fysiska butiken in i den digitala butiken för att förmedla en bra varumärkesupplevelse?SlutsatsDenna studie grundade sig på en modell som beskriver hur en bra användarupplevelse kan skapas.
Viltets inverkan på vegetationsutvecklingen i en Sydsvensk skogsföryngring :
Herbivore impact on the Swedish forest has under a long time been a common subject of
debate. There are many different opinions depending on what direction the forest owner has with his/her forest. Populations of moose and roe deer have increased significantly in Sweden during the last decades. The purpose of this study is to get a full picture of the herbivore impact on the regeneration areas. The field work was done once a year for seven years (1999?2005).
