Sönderdelning av plogtilta med skärknivar :

During the last couple of years it has been more important to reduce the driving on the field to prepair the soil after ploughing. The machine costs are high so it is necessary to be effective. To reach a pleasant soilbed directly after ploughing is sometimes possible on easier soils but heavier clay soils always need more tillages. There is a lot of equipment mounted on the ploughs on the market, for example Furrow Cracker and Furrow presses, which makes a pleasant soilbed on easier soils. The last year Överum and Kverneland have presented knives which are mounted on the wing or moulboard.

Uppfatta och reagera : En kvalitativ studie om IT-relaterade resursers roll i kundkännedomsprocesser och kundresponskapacitet

The structures of organizations have gone through a dramatic change over the last years; as a result customer service is no longer a small side activity but a critical part in customer relationship management. Development in information technology has created opportunities as well as challenges for organizations when it comes to providing a customer service with capacity of sensing and responding to customers' needs. Previous research shows a relationship between customer response capability and customer knowledge processeses, this study investigates and confirms this relationship. However, findings show that dedication and understanding for customers needs has a direct impact on both customer response capability and customer knowledge processeses, this result indicates that customer knowledge processes and customer relationship management are difficult to differentiate. Furthermore, this study explores IT-related resources impact on customer response capability and customer knowledge processes.

Läsning - en nutida klassfråga? : En studie av sex svensklärarstudenters läsvanor ur ett sociologiskt perspektiv

The aim of this Master?s thesis is to investigate if the reading habits of teacher students are influenced by merit and descent. The empiric material consists of six questionnaires answered by students at the teacher training with Swedish at the upper secondary school as their first topic. The questionnaire comprised questions about reading habits in the childhood and today and information concerning merits and descent.Pierre Bourdieu?s sociological ideas about cultural capital transmitted from parent to child and the concept of habitus are used as a theoretical framework regarding descent.

Design and Analysis of an All-optical Free-space Communication Link

Free Space Optics (FSO) has received a great deal of attention lately both in the military and civilian information society due to its potentially high capacity, rapid deployment, portability and high security from deception and jamming. The main issue is that severe weather can have a detrimental impact on the performance, which may result in an inadequate availability. This report contains a feasibility study for an all-optical free-space link intended for short-range communication (200-500 m). Laboratory tests have been performed to evaluate the link design. Field tests were made to investigate availability and error performance under the influence of different weather conditions.

The intention was also to explore differences between men and women in the occurrence of symptoms of depression. Furthermore, the prevalence of symptoms of depression among patients with cardiac arrhythmias was compared with a Swedish general population. Method: For two weeks MADRS-S, a self-rating scale for depression, were distributed at a medicine ward where patients with cardiac arrhythmias are treated, at a hospital in Sweden.

Anslutning av vindkraft till ett svagt nät i Tidaholm

Vindkraftverk ansluts idag i snabb takt till elnät runt om i världen. Elnäten är ofta inte tillräckligt dimensionerade på platser där vindkraftutbyggnad är lämplig vilket leder till ett behov av nätförstärkning. Förstärkning sker konventionellt genom att övergå till en högre spänning, något som kan vara förenat med stora kostnader och ledtider. Bland annat därför har en filosofi med beteckningen smarta elnät uppstått, som handlar om hur elnätsystemet ska se ut när det är mer anpassat till de nya energikällornas karaktär och samtidigt medför ett mer effektivt totalutnyttjande. För vindkraftverk kan det då handla om att i högre grad än idag reglera produktionen och understödja nätet, t.ex.

Odlingens och lagringens inverkan på utsädes grobarhet :

At seed-growing the aim is to produce a commodity with high germination capacity, good soundness and purity, and also slight admixture of seeds from other species. The capacity of germination and the vigour of the seeds may become impaired in consequence of mechanical damage, infection of diseases, growth of mould, attacks of vermin, high drying temperature, secret germination, sprouting in the ears etc. The germ belongs to the outer and most unprotected parts of the seed, and consequently this is much exposed. Even quite sound seeds can instantaneously have low capability of germination. It can be due to the fact that the seeds are in rest of germination, i.e.

Effektivare hantering av foderspannmål : en fallstudie

The purpose with this work was to investigate some alternatives for an effective handling with grain, to find the most economic alternative. It is not common that moisture content is below 14% when harvesting grain in Sweden. To store the grain safe it has to be preserved in some way. I have described some of the most common systems for preserving grain in this paper. I have used the systems as a basis when I made calculations in handling the grain for a company. I have chosen a company placed in south of Sweden. The productions are crop farming and pork.

Arbete med aktivering : En kvalitativ studie om hur socialsekreterare arbetar med aktivering av försörjningsstödstagare

Syftet med uppsatsen är att studera hur socialsekreterare arbetar med aktivering av försörjningsstödstagare och vilka faktorer som påverkar arbetet med aktiveringen. Materialet för studien består av fyra intervjuer med socialsekreterare som arbetar med ekonomiskt bistånd i en kommun i Sverige. Resultaten visar att aktivering av arbetslösa försörjningsstödstagare utförs i form av jobbaktivering eller resursaktivering. Alla intervjuade socialsekreterare ser på aktivering som en bra och nödvändig åtgärd, som både har en stöttande och kontrollerande funktion med tyngdpunkt på stöd. Vidare visar resultaten att det finns faktorer på tre nivåer som påverkar arbete med aktivering:Samhällsnivå: Socialtjänstlagen, arbetsmarknaden, politiska beslut, skärpta regelverk, information och samverkan;Organisationsnivå: otydligt uppdrag, riktlinjer och kriterier; resursbrist, tidsbrist, arbetsbelastning, bristande samverkan, bristande information;Individnivå: socialsekreterarens erfarenhet och utbildning, syn på aktivering; klienteras utbildning, arbetslivserfarenheter, motivation, socialkompetens och eventuella individuell problematik, önskningar, mål och syn på framtid, tidigare erfarenheter av kontakt med socialtjänsten..

Utvärdering av den biologiska reningen av processavloppsvattnet vid GE Healthcare i Uppsala

GE Healthcare operates in Uppsala (Sweden) and develops systems, equipments and medium to purify medical substances. Discussions with the local authority concerning planed far-reaching changes and upgrades of the biological process techniques for sewage management, aroused the question about revising the terms of permit for the activity. Therefore it seemed necessary to evaluate a newly installed biological process technique, which is the background of this thesis. The evaluated biological treatment process was built in 2003 and consists of a biological reactor filled with moving bed carriers with a high surface area for biological growth. At the time of the project the biological wastewater treatment plant consisted of a flow equalization facility and two following parallel biological processes; a biological reactor with moving bed carriers and a tower trickling filter.The aim of this thesis was to survey the function of the biological reactor with respect to the reduction of organic matter.

Identifiering av röjningsbestånd med hjälp av flygburen laserskanning

Bergvik Skog is one of the leading forest companies in Sweden who use airborne laser scanning for forestry information. They utilize laser data retrieved by the Swedish National Land Survey to describe the forest holdings and facilitate planning for thinning and final felling operations. However, the possibility to identify stands with clearing needs by using laser scanning data has not been tested in a large scale. The data used in the current study are field data from The Swedish National Forest Inventory in combination with laser data from the Swedish National Land Survey acquired in 2009. The collected data is used to find one or several laser variables that best describe the relationship of the field measured samples with clearing needs.
