Vinderosion på jordbruksmark har länge varit ett välkänt faktum trots att någon utförligare undersökning om dess omfattning och skadeverkan inte tidigare genomförts. Mot bakgrund av detta har därför ett nordeuropeiskt projekt, WEELS (Wind Erosion on European Light Soils), dragits i gång som syftar till kartlägga vinderosionen på sandig jordbruksmark i norra Europa och som man i slutändan hoppas ska kunna resultera i en vinderosionsmodell. Detta har genomförts med SOIL modellen, en matematiskt fysikaliskt baserad modell för simulering av vatten och värmeflöde i en skiktad jordmånsprofil..

Spra?kbruk inneha?ller till stor del konventionaliserade spra?kliga mo?nster. Det kan handla om specifika ord, mer eller mindre fasta eller kompositionella flerordsenheter, hela yttranden eller grammatiska strukturer. En god ka?nnedom av dessa spra?kliga mo?nster ho?jer graden av idiomaticitet i spra?kanva?ndningen.

Under de senaste 300 åren har jordbrukslandskapet i Sverige genomgått stora förändringar. I början av 1900-talet introducerades konstgödslet och efter andra världskriget ökade gödslingen dramatiskt i syfte att maximera produktionen. Detta har lett till att överskottet av kväve har spolats ut i vattendragen. I detta arbete har stor vikt lagts vid att skapa en egen kvävemodell i syfte att simulera kväveläckaget från jordbruksmarken i Tolångaåns dräneringsområde..

Background: Ill-health related to unhealthy lifestyle is increasing and despite existing knowledge about healthy lifestyle it is difficult to change behaviour. Counselling in the primary health care is often superficial and without critical elements for behaviour change. Aim: The aim of this paper to elucidate interventions for change of lifestyle with respect diet and physical activity. Method: A literature review was carried out and ten scientific articles were analyzed and compiled in two main categories: design of these interventions and participation in them. Results: Education, decision making, goal setting, feedback, social support and follow-up were identified as critical elements for behaviour change.

Den svenska skolan innefattar i dagens globaliserade samha?lle elever fra?n alla va?rldens ho?rn och i den svenska grundskolan talas det idag cirka 200 olika spra?k. Mitt intresse fo?r skolan ligger framfo?rallt i hur skolan ska kunna anpassa sig efter en alltmer globaliserad va?rld da?r olika spra?k, kulturer och kunskaper ma?ste samsas och hitta en gemensam grund att sta? pa?. Men fra?gan a?r om synen pa? spra?k och kunskap ha?nger med i globaliseringstanken eller om kunskapen fortfarande i stor utstra?ckning a?r kopplat till vad vi i Sverige anser vara den ?ra?tta? kunskapen.

The purpose of this thesis work is to evaluate how the physical behaviour of a pipe bend is affected by the pipe bending procedure. Effects such as initial ovalization, thinning, thickening and plastic hardening from the bending procedure are examined and the mechanical properties of pipe bends containing these effects are investigated.This has been evaluated by creating a detailed Finite Element model of a pipe that is being bent. Then the differences compared to a bent tube in a virgin state, so called Elbow elements and an analytical in-house program have been evaluated. The virgin state refers to a model of a pipe that is bent from the beginning, thus having a homogeneous thickness and not containing any plastic hardening. The Elbow element is a calculationally cheap element, specially developed for accurate calculations of pipe bends in an initially virgin state.The goal with the thesis work is to get a better picture of what happens to a pipe as it is being bent, how this affects the mechanical properties and to evaluate the possibility to develop an easy method for taking these effects into account when using the Elbow element.This report describes the layout of the work and how the detailed FE-model has been constructed.

The essay examines managers reflection after attending a leader development program. When examining their thoughts the author starts out from the assumption that leader development programs with reflecting elements can create reflection on management/leadership and the organisations management behaviour. The examination is done whit help of a case study on a company in the paint industry. To test the assumption the author uses a combination of questioners and interviews on eight managers who has finished a leader development program. The result is analysed by bringing forward the managers general assumptions an by finding relations between opinions on needs, existing norms and preferred management/leadership.

Today's urban centers become denser, which contributes to higher demands on sound and noise. It is therefore highly relevant to build homes with good sound environment while maintaining living space. This thesis aimed to reduce the current concrete walls and see how the mass law affects the reduction index value and flanking transmissions. Handmade calculations were calculated according to the Swedish standard SS-EN 21354-1, where only air sound was calculated.Calculations we­­­re performed on wall elements with different weights and thicknesses, and compared with results from Bastian.In Bastian calculations of flanking transmissions were also made, this was made to see the impact of the flanking transmission when changing the mass per unit area. Mass law's impact was examined by flanking transmission and the result shows that they are not affected as long as the ratio between the thickness and the density remains the same.A questionnaire survey was conducted to determine the actual sound experience; this questionnaire was conducted on three concrete buildings in Växjö.

Syfte: Studiens syfte ?r att unders?ka hur undervisningen kan utvecklas med hj?lp av elevers reflektion i aktionsforskning, vilka hinder och m?jligheter som uppst?r n?r nya kulturella redskap pr?vas och inf?rs i undervisning, samt att f? en f?rst?else f?r elevernas kommunikativa processer och upplevelse av sitt intresse och sin delaktighet som kan bidra till l?rande och utveckling i NO undervisning. Teori: Studien antar ett sociokulturellt perspektiv och teori som resonerar elevers l?rande, intresse och delaktighet. Perspektivet fokuserar p? kommunikativa processer och reflektioner i l?rande utifr?n S?lj? och Illeris teorier. Det syns?ttet och perspektivet inneb?r att l?rande sker ofta ihop med andra genom deltagande i ?msesidiga aktiviteter, d?r l?rande fokuserar mest p? det sociala samspelet. Metod: Studien baserar och utg?r fr?n en aktionsforskningsansats som en kvalitativ metod f?r att unders?ka och besvara forskningsfr?gorna.

Mitt projekt har handlat om att ta steget till att bli mer sja?lvsta?ndig vid instuderingen av nya stycken. Att va?ga go?ra saker utan la?rarens hja?lp och lita pa? sin egen intuition och kunskap. Jag valde att arbeta med stycket Sonat no.

ABSTRACT This study is an exam work at the Department of Ecology at the Swedish Agricultural University, Ultuna, Uppsala. The field work was performed in the counties of Uppsala and Västmanland. Grassland areas, exposed to annual mowing, are known to host a variety of rare and red-listed vascular species. The area of these grassland are, however, decreasing in the landscape due to modern farming. The fact that roadside verges maintain regular mowing has proven to be a successful concept for many rare vascular plant species in this habitat. Vascular plants along roadside verges at the State road network were inventoried due to a government mandate during 1995 and 1996. As a result ?Species rich roadsides? were pointed out.

This paper aims to describe how religion teachers in Swedish schools teach concerning questions about life issues and popular culture. To research the teachers' didactic approach to these issues, didactics has been defined with three educational questions: what, how and why. The essay focuses on teachers' effective implementation of teaching on life issues and popular culture, which we used a theory of offering meaningfulness describing what subject matter that may be imparted to the students. An offer of meaningfulness can be pursued and can be made visible in the context of what and how performs the teaching and also in the context where the teacher planned the teaching elements. The method that the paper has used is the interviews of four different active religious educators in Stockholm and Uppsala area.

This is an investigation of a mobile prefabrication factory´s competitiveness and profitability which also will result in a suggestion for a design of the factory. The mobile prefabrication factory is an idea of a new concept for production which is meant to be used in the manufacture of slab. The main intention with this concept is that by using a fast established prefabrication factory to produce elements near the construction site, thus avoiding transport from the factory to the building site. This means not only an environmental and economic gain, but also that you can avoid risking damage the elements which often occur during transportation. The contractor is owner of the mobile prefabrication factory and can thus avoid long waiting times and cyclicality.

The aim of this study is to investigate how the Swedish language proficiency of pupils in vocational programmes in 1977 was measured and assessed with the aid of a national achievement test, and to investigate whether vocational pupils today, in 2014, have similar language proficiency to that of pupils in the 1970s. The study also discusses how the design of the national achievement test from 1977 reflects the view of knowledge that prevailed in society and in the policy documents. The material for the study consists of a total of 75 national achievement tests, 40 of which were taken by pupils on a vocational programme in 1977 and 35 by pupils on a vocational programme in 2014. The national achievement test consists of two parts, the first of which focuses on isolated elements of language proficiency, while the second involves free text production. The material was analysed quantitatively in accordance with the correction material from 1977.
