Kreditgivning till lantbruksföretag : en jämförelse mellan Sverige och Danmark

In relation with structure transformation in farm companies with bigger animal population and pressure at the milk price, the farmers in both countries have to invest more money in the company to endure. This had conduct what more owners had seen grown requirements to invest in bigger population barns. The investment is necessary to retain stability in the economy for the companies, at that time when the profitability for small production barns decrease. This essay carries out through a case, there the activities main part are milk production. The present operation consists of 82 milk cows in long stall with a yield on 10 500 kg ECM. The idea is that the company should increase the activity to 180 cows.

DIDAKTISKA PERSPEKTIV P? EN BILDUNG-ORIENTERAD BIOLOGIUNDERVISNING -en analys utifr?n tysk bildningstradition med exempel fr?n biologil?rares praktik p? folkh?gskola

Aim: The aim of the study is to show how a Bildung-oriented biology teaching could be designed, along with providing classroom examples of such teaching. In this study, the term Bildung, is defined based on the German Didaktik tradition as competences for self-determination, constructive participation in society, and solidarity. Theory: The study is based om Englund?s thoughts of teaching as didactic choices that express different views of meaning, socialisation, method, and context. This is referred to as companion meanings. Additionally, the theoretical framework is influenced by Gadamer?s thoughts on understanding through dialogue and Klafki?s didactic analysis of educational content for Bildung-orientated approaches. Method: The empirical qualitative study is based on ten semi-structured interviews of biology teachers at Swedish Folkh?gskola.

Interaktiv arbetsbeskrivning

Under framtagandet av nya produkter måste ett antal prototyper tillverkas för att verifiera konstruktionen. För en metodingenjör som tar fram reparationsmetoder innebär prototyptillverkning att tankar som växt fram under utvecklingsfasen kan provas för första gången på en fysisk produkt. Detta sker relativt sent i produktutvecklingen och eventuella ändringar som kan uppstå på grund av att servicevänlighet inte uppnås blir mycket kostsamma. Om däremot prototypen där metoderna verifieras för första gången är digital och detta sker tidigt blir kostnaderna för eventuella ändringar avsevärt mycket mindre. Modellen som ligger till grund för metodstudierna kan sedan används för att skapa ett utkast till service litteratur, detta medför att även den delen av slutprodukten kommer att vara i fas med övriga utvecklings avdelningar. Under detta projekt har en digital prototyp av en Scania motor använts för genomförandet av metodstudier.

Förändring av pappersegenskaper vid lagring under dragspänning

SammanfattningI en pappersrulle är de yttre lagren utsatta för dragspänning. Om det finns variationer i rullens diameter i form av valkar finns det risk för att papperet förlängs irreversibelt i dessa positioner och orsaka slappa stråk. Den deformation som uppstår vid långvarig belastning av papper kallas krypning.Uppgiften i detta arbete var, att på lab., simulera valkar genom att utsätta pappersremsor för konstant dragspänning av olika storlekar. En av frågeställningarna var om egenskapsförändringar kan påvisas när papper utsätts för konstant inspänningskraft under en längre tid. De parametrar som undersökts var töjning, kryphastighet och relaxation, även mätningar på papperets mekaniska egenskaper dragstyrka, brottöjning och dragstyvhet har utförts i detta arbete.De papperskvalitéer som undersöktes var 71g/m2 MG-papper, 80g/m2 optisk liner och 135g/m2 liner.

Tjänstekvalitet för pensionssparande : En studie om vilka faktorer som påverkar den upplevda tjänstekvaliteten för pensionssparande

Our purpose of this paper is to seek an understanding of which service quality factors that affects customers in their decision making progress regarding purchasing financial services such as pension products. We also seek to evaluate the different service quality factors by compare their relative strength against each other. The study aim to investigate if there are any connections between customer behavior variables such as gender, age and income in comparison to these service quality factors related to pension products.The findings aim to help a small financial institute such as our case company Plain Capital to understand how their customers experience service quality regarding pension products.In order to find empirical results we conducted a qualitative research as well a quantitative research. The qualitative research employed both a focus group interview with pension savers and an interview with our case company Plain Capital. We were able to identify the service quality factors for pension?s products with help from the focus group interview.

Syntes av hydroxyapatit/ nanocellulosa kompositer

Cellulose nanocrystals (CNC) are great candidates for composite materials. The reasons why CNCs are such attractive materials for them are due to their great mechanical properties, high aspect ratio and low density. On the other hand, hydroxyapatite (HAp) is a kind of calcium phosphate and a main component of bones and teeth. The purpose of the present study is to make oriented nano-sized composites with CNC and HAp. Although some researchers carried out to make CNC composites with HAp for biomedical materials, nano-sized and oriented ones haven?t been achieved yet.

Välfärd, jämställdhet och demokrati

The purpose of the essay is to analyze the welfare state from a gender perspective. Further, the paper analyzes and critically examines three different normative solutions provided by Irish Marion Young, Nancy Fraser and Jürgen Habermas for the realization of a welfare state that includes women.Habermas argues that the welfare state has created a situation of dependency and state paternalism which reduces both individual and collective self-determination. Young follows Habermas? argument. She argues for a political climate where justice is reduced to the distribution of material goods rather than the elimination of underlying relations of domination and gender specific patterns.

Påverkar fysisk aktivitet det psykiska välbefinnandet, med inriktning fysisk självuppfattning och självkänsla, hos äldre?

Studier som berör ämnet hur fysisk aktivitet påverkar det psykiska välbefinnandet hos äldre är något som berör alla. Fysisk aktivitet har i tidigare forskning visat sig påverka båda den fysiska och psykiska hälsan positivt. Mycket forskning är gjord på området, dock är de äldre underrepresenterade som målgrupp inom området. Syftet med denna studie var att undersöka i vilken utsträckning fysisk aktivitet påverkar det psykiska välbefinnandet, med inriktning självkänsla och fysisk självuppfattning, hos äldre. Undersökningen innefattade en experimentell undersökningsmetod med en randominiserad, kontrollerad design.

Utvärdering av fjädrande statorfötter : Nytt koncept i vattenkraftgeneratorer

This thesis is an evaluation of a new design concept for statorfeets in Gallejaur hydro power plant. Founder of the work is Vattenfall AB Vattenkraft. During the 70- and 80´s nuclear power began to be phased in to the Swedish grid, which meant that hydropower became an important source of rules. The generators began running in so called intermittent operations instead of basic operations, which meant 300-600 start/stop per year instead of one-ten numbers start/stop per year. In order to deal with the thermal forces that arise at every start and stop suppliers began to mount so called sliding joints, which is to take advantage of these forces and maintain the stator shape.
