Vivlar på prydnadsbuskar - nya arter eller förändringar i födopreferenser?
During the last couple of years leaf-edge-cuts, typical to Otiorhynchus wingless-weevils, have been discovered on ornamental shrubs, especially Syringa vulgaris lilac and Ligustrum vulgare privet. These plant species have not earlier been attacked by wingless-weevils and because of that, the aim of this study is to see if new species of weevils have been established in Sweden or if the domestic weevils have changed their food preferences. This work also includes a literature study of known weevil species in Sweden and their host plants, and of wingless-weevil species in Europe that could be invasive here. Locations, where damage to previously named plants has been reported, have been examined. The extension and appearances of the damages have been documented in order to study if different weevil species make different types of edge-cuts.
Dämplindningens inverkan på spänningens kurvform i en vattenkraftsgenerator
Harmonics are a well-known problem that has to be dealt with in the design of thegenerator. Internationally accepted standards limits the amount of harmonics allowedin the no-load voltage. These limits can be difficult to fulfill with integral slot winding,where the number of slots per pole and phase is an integer. The presence of thedamper winding often makes the problem with harmonics even worse and harmonicswith frequencies of order 6q±1 arise with significant amplitude. How the damperwinding is designed affect the content of harmonics in the no-load voltage and the aimwith these ? has been to investigate in which extent design of the damper windingaffects the contents of harmonics.Simulations with the 2-D finite element method have showed that if the damper barsis centered in the pole shoe, the amplitude of the harmonics of order 6q±1dependsboth on the ratio between the stator slot pitch and damper bars slot pitch and if thedamper bars are connected between the poles or not.If the damper bars is displaced with ¼ stator slot pitch alternately, the amplitude ofthe harmonics of order 6q±1 is reduced and the influence of the ratio between thestator slot pitch and the damper bars slot pitch will vanish.
Den erfarne ripjägaren : Optimalt födosök hos homo sapiens?
The purpose of this study is to examine some factors that make a human grouse hunter to prolong and increase its hunting effort. The theory of optimal foraging is used for explaining their behavior.The data of this study is collected from a web-based inquiry from 2007 answered by grouse hunters in Sweden. The method that has been used is mainly bivariate statistics and logistic regression analysis.Key findings shows that an experienced grouse hunter has more than 5 times the chance of prolonging hunting effort when grouse density is high, compared to a beginner grouse hunter. On the same time experienced grouse hunters also stop hunting in advance when grouse density is low to a larger extent than inexperienced hunters. Other factors of importance for prolonging the hunting effort for a day are age and the travel distance to the hunting area.
Utfodring av rapsfoderråvara i fodersystem till mjölkkor
The feed is a major cost in the dairy production and there is a constant interest in findingalternative cost-effective feedstuffs. Competitive dairy producers have to seek ways todecrease their production costs and the pursuit of cost-effective feed rations contributesto lower costs of production. An interesting group of protein concentrates are rapeseedproducts like ExPro (heat treated rapeseed) which have during the autumn 2008 andspring 2009 been very favourable compared to other protein feeds.This study focuses on the feedstuff products ExPro and Raps-Drank 60/40 (rapeseeddistillersgrain). The potential use of ExPro in dairy cow feed rations are also explored.ExPro is a well known feedstuff but Raps-Drank 60/40 is a relatively new product andnot known for many farmers.A field study on the use of rapeseed products was made on a limited number of dairyfarms. The main purpose was to study the management of the feedstuffs on the farms.The Farms were selected in cooperation with two local extension services.
Etablering i främmande kulturer : En fallstudie över små svenska tekoföretags etablering i Spanien
This bachelor of economics paper discuss that the increasing globalization has put the small companies in the Swedish textile and clothing industry in a situation where internationalization has become a necessity. Furthermore has the European Union lead to that this type of companies has to seek growth on foreign markets with great socio cultural distance from the home country, Sweden. Nowadays there?s no time to internationalize in the same course of action like before. Before, the Swedish companies begun their operations abroad in fairly nearby countries and only gradually penetrated more far-flung markets.
En praktisk lösning - om styrningsteknologier inom könsutredningar
The purpose of this article is to explore the technologies of government that are created within gender disorder assessments as an institution. I have done so by utilizing Norman Faircloughs discourse analysing instrument ?communicative action?, which focus on the social institution as relational.The material is strategically chosen by gathering texts from the Swedish state, the psychiatric clinics, NGO:s and by performing interviews with transsexual patients.When analysing the communication of the main agents, I have concluded that practices highly are a result of repeating text and speech inside the institution. The psychiatric assessments can also be seen as an illustration in changes in how citizens are governed in advanced liberal societies, where the role of the state has been gradually reduced in favour of other agents.I consider that the change illustrates an ?acting at a distance?-mentality where the patient is introduced to participate in the definition of the care in what I call ?negotiation as a technology?.
Intern materialhanteringsutveckling på Kongsberg Automotive AB
This examination report is a part of a program for Industrial organisation and Economics with specialization in Logistics and Management at Jönköping University. The report contains an analysis of the internal material handling at Kongsberg Automotive, and also an improvement proposal for a new material handling system.The aim with the report is to find a better material handling system and also make an analyse of the existing system. The goal is to shorten the distance for the operators when they order material, and also to increase the productivity.The investigation methods for the report have for the most part consisted of observations and interviews of key-persons who daily work in the production. During some time the actual material handling-system has been observed and some shortcomings have been discovered, and these are also discussed in the report.The shortcomings that have been discovered are for once the indistinct signal that should signal need of material in the production. Some other activities have also been discovered that does not bring any value into the final products.
Organisationskultur i en processorganistion
At the beginning of the nineties, a new form of organisation, the process organisation, was about to be born. The features of the process organisation were a flexible organisational that works in a world where the pace of development is increasing all the time. Today there are many organisations that have mapped their processes, but in order to truly become a process organisation, the processes among other things have to be in harmony with e.g. organisational culture. Which effects the organisational culture has on the process organisation is yet unexplored, but however quite crucial.
Från boklådor till agentbyrå - läsfrämjande åtgärder för barn och ungdomar i Jämtlands läns glesbygd åren 1997-1999
The purpose of this master thesis is to examine how librarians/cultural workers act in projects in order to stimulate and promote reading among children and youth in sparsely populated regions in the county of Jämtland during a period of three years, and if/how these projects differ. The examination is based upon the progress of these projects in four of eight communities. Four librarians and two cultural workers have been interviewed in order to get their view of the proceedings of the projects. The results indicate that the four communities all made up plans for three years but in different ways. They mainly collaborated with the school but also with the board of children's health and the preparatory school.
Att spela ett yrke : En kvantitativ studie om svenska speljournalister och deras professionalisering
This work aims to improve our knowledge about Swedish video game journalists, a new occupation in a quickly expanding business. Through a survey sent out to over 50 Swedish video game journalists, the result indicate some unexpected facts. Men largely dominate the profession; just 10 % of the work forces are females. This relation was notable in our survey, as well as in earlier studies. Video game journalists between 26 and 35 years old seems to be the largest age group, which we think is a bit surprising considering how new this form of journalism is, and the fact the internet provides opportunities for every enthusiastic video game writer.
Sensus Barnmusikskola i Karlstad : Att nå ut för att främja integration och mångfald under perioden 2009-2012.
This is a study of Sensus Barnmusikskola ? Children?s School of Music, in Karlstad, Sweden?s attempts to facilitate integration and diversity in their operation. The Culture and Recreation Management in Karlstad town?s conditions to award the school their grant in 2009 was that Sensus Children?s school of Music should make targeted interventions in the socioeconomic exposed areas Gruvlyckan/Våxnäs and Kronoparken to increase the number of children with foreign background. This would according to the Culture and Recreation Management bring more integration and diversity in to the school?s operation.
En studie om påverkan på kontrastkänsligheten vid olika additioner på en multifokal kontaktlins
Syfte: Att mäta kontrastkänsligheten på en multifokal kontaktlins, med tre olika additioner för att se om kontrastkänsligheten ändras med olika additioner.Metod: 19 personer deltog i studien. En Biofinity multifokal CD (center distance) kontaktlins valdes till studien. Testet gjordes med tre olika additioner, en låg addition på +1,00 D, en mellanaddition på +1,50 D och en hög addition på +2,00 D och även med en kontaktlins utan addition som också var Biofinity. Mätning av hög- och lågkontrastvisus 10 % gjordes med samtliga kontaktlinser.Resultat: Medelvärdet för högkontrastvisus var -0,15 logMAR för linsen utan addition, och något högre dvs. sämre visus med addition.
Omega System Kalibrering: Strål X-Separation mätning och kalibrering
Micronic Laser Systems AB produces and develops machines for the photo mask production market. One of their products is the Omega machine which exposes photo masks using 5 laser beams simultaneously. It is important that the distance between the each laser beam, the x-separation, is the same. The x-separation is today measured by exposing a photo mask with a certain pattern and thereafter measured with a metrology system. This takes to much time and it is desired to find a faster method to measure the x-separation without loosing precision.The task for this master thesis is to improve an existing measurement method which uses a calibration mask.
