Examination of mycorrhizal associations of Allanblackia stuhlmannii : a tree under current domestication

Allanblackia is a tree genus native to humid forests in West, Central and East Africa. Its fruits contain large seeds from which edible high-quality fat can be extracted. In order to create a sustainable supply chain of Allanblackia seeds, a domestication program has been initiated with the purpose to enable smallholder farmers to grow the tree as an agroforestry component and cash crop. More knowledge is required to understand the tree?s biology and possible symbioses involving soil microorganisms with plant growth enhancing poten-tial.

Validering av smärtformulär för katt

The objective of this study was to assess validity and reliability for five different owner-completed instruments evaluated to assess chronic musculoskeletal pain in cats. All of the instruments were questionnaires, three asking about behavioral changes, one about the degree of pain and one about quality of life. One of the instruments was written originally in Swedish, the other four instruments were translated into Swedish before use. Data available were records from 57 cats with no signs of pain and 11 cats with different pain-related diagnoses. The diagnoses were ensured by clinical examination including palpation and manipulation of joints, gait testing on a force-plate and X-ray scans. Instrument 1 was completed by 57 pain-free and 11 pain-affected cats.

Hela världen i en matris

Of all observable societal trends, the proliferation of standardizing processes is striking. Auditing standards are an illustrative example of this. Not only privately owned companies must today make available numbers and key figures to satisfy needs of information and knowledge. Government agencies are increasingly conforming to this trend, adopting standards for quality assurance and monitoring, producing numbers and annual reports ? despite their somewhat ambiguous task and role.

Modellbaserad temperaturregleringav partikelfiltrets regenereringsprocess

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

Etnocid i Kosovo ? språk och kultur som vapen i en etno-politisk konflikt

The aim of this master's thesis is to describe the role of language and culture as ethnical identification factors and illustrate how these have been used as political weapons by the Serb regime in Kosovo during the last decade. The thesis discusses the concept of ethnicity, the relations between the politics of identity, nationalism, ethnic mobilization and the importance of language and culture. Kosovo has historically been characterized by severe ethnic antagonism between Serbs and Albanians. Different languages, cultures and religions beside political processes led to ethnic cleavages that paved the way for ethnocentrism, ethnonationalism, chauvinism, ethnic cleansing and civil war. Since 1989, the Serbian authorities have intervened in all important spheres of life, in an attempt to Serbianize Kosovo.

Förstudie för skapandet av ett miljöövervakningsprogram : en styrkeanalys angående vattendrag i västerhavets vattendistrikt för fastställandet av provantal i tid och rum för ett effektivt omdrevsprogram

The environmental monitoring in Sweden has been developed by several different parties and is now being coordinated and made more effective in order to meet the current demands on high quality information regarding the state of the environment. Sweden has been divided into five different water districts based on watershed areas because of requirements in the Water Directive of the EU. In Sweden there are two common types of environmental monitoring programs used to gather information on changes in time and in space. Currently both these two types are used for lakes in the water district of the western sea but only one is used for watersheds. The purpose of this report is to supply basic information regarding the possible need for a second environmental monitoring program for watersheds in order to better describe the spatial variation within the district as well as to determine the number of samples necessary in order to describe the district over time and space.

Robotiserad produktionsanpassad magnetmontering för vågkraftverk

This thesis work includes studies and simulation how magnetization of the translator in a linear generator for wave power can be automated. The translator is the moving component in the generator that is "dressed" with permanent magnets. The translator is magnetized with rectangle-shaped permanent magnets that are today's strongest permanent magnet type of neodymium-iron-boron (NdFeB).Eight equivalent metal sheets are mounted around the translator. The plates have milled tracks where 106 permanent magnets per sheet are mounted. Today the assembling of the magnets is done by hand, which is a very tedious and time-consuming work.  This project presents investigations about the automation of the translator magnetization theoretically and simulation results are preformed in ABB's robot simulation software RobotStudio. Even robot-held tool was designed that enables the robot to be able to magnetize the translator in a simple manner.  The investment cost is roughly 1.5 million SEK. With an economic life-time of five years, the investment costs are estimated to 24000 SEK / month.  According to the calculations, this project is very motivated to implement, as it provides savings up to 17 000 SEK per translator which is 10.2 million SEK assuming that the robot cell is operating at full speed the whole year.According to this thesis work the result is a 4x9 meter cell with two industrial robots of the type ABB IRB6650S.The cycle time to magnetize one translator was calculated to about 10 hours.This prototype of project can possibly be implemented in a full-scale production line and performed according to the calculations and simulations presented in the report. Further work is suggested to improve the tool.Lyssna .

Kommunikationsfärdigheter hos förskolebarn : Funktion, kontext och kommunikativa handlingar i samspel

According to international and national literacy studies (PISA, PIRLS) Swedish boys are inferior to Swedish girls when it comes to reading. There can be numerous reasons to that statement. One is that Swedish teachers require more knowledge about communication as an important component in literacy. In spite of this shortcoming, Swedish girls manage to gain sufficient literacy. Why is that? The aim of this survey was to examine if there were any differences between girls and boys regarding communication skills when they begin in school.The main questions taken in account were:Which differences and/or similarities in communication skills are discernible between boys and girls this particular preschool?How do boys and girls communicate with each other in different room contexts on this particular preschool?           To be able to answer the questions, I adopted observations and audio recordings from children aged five.

Effects of milking system on plasmin and plasminogen activity in bovine bulk milk

Protein is an important component in various milk products and has a crucial role in the final quality. Excluding non-protein nitrogen, bovine milk contains about 3.3% protein whereas about 80% of this fraction consists of casein. There are four major members in the casein family: ?s1-casein, ?s2- casein, ?-casein and ?-casein. Proteolytic enzymes are the cause of degradation of the economically important milk proteins.

ADS och Matlab för optimering av pre-distortion av effektförstärkare

This master?s thesis deals with integrating simulations using Agilents Electronic Design Automation tool ADS with customized Matlab scripts, for solving complex analog and digital radio architectures. In particular, it addresses predistortion, realized in the digital domain, of power amplifiers, modeled in the analog domain. The former is implemented in Matlab while the latter is implemented in ADS. Two versions of integrating the two systems have been tested: 1) Iterative approach on sample basis and 2) Scheduled batch solution by matrix inversion.

Our aim was to, from the actors? point of view explore what impact their values, experiences and thoughts have on their identity as individuals as well as a collectivity. We also investigated which symbols that are significant for this group. For this essay a qualitative method was used; we conducted nine individual interviews and one group interview with young skaters from the ages of 15-17.

DFM för Lasersvetsning

 The purpose with this thesis was to develop a designguideline which will simplify the development of new products that will be laser welded. The need for this thesis has come forward from the quality problems that Volvo Construction Equipment, Components Division is having with their laser welding manufacturing unit. The reason for the problems emerges from the bad communication between the development unit and the manufacturing unit within the company when the products produced today was developed. This resulted in products that were hard to and in some cases almost impossible to weld. To avoid these problems from occurring again it was needed to gather the experiences within this area and compile it and present in a brief a pedagogical manner. The information for the groundwork of our results has been gathered by interviews of several key persons in Volvo Construction Equipment, Components Division.

För Sverige i tiden? : En studie om den svenska monarkins relation till samhället och sekulariseringsprocessen mellan 1858-2012

Christendom has under a long period of time in Swedish history been the central component in legitimating the monarchs' power, a continuous process than can be clearly observed through the customs of royal coronation and baptism rites. However, during the 20th century those close ties between the state and the church of Sweden have been dissolving at a steady rate, alongside a growing societal democratization and modernization process. Officially the monarch still had a clear constitutional power legitimated through the transcendent, but unofficially his power was in reality heavily reduced. How do the Swedish monarchy relate to a rapidly changing society and secularization process? This pilot study investigates this relation by analyzing the news reports of the royal coronation and baptism rites between 1858 and 2012 from two leading newspapers, Aftonbladet and Dagens Nyheter.
