Bergerosion i utskovskanaler

Today?s climate changes will probably give rise to precipitation in Sweden, which will cause more floods in Swedish rivers. Many of the Swedish rivers are regulated and have lots of hydro-electro power plants. Higher floods in the rivers will give greater water loads on the dams, which mean that a higher discharge through the sluice gates and in the spillway channels is needed. High discharge of water in a spillway channel can create scour of the material in the channel.

Upplevelser hos socialsekreterare som arbetar med barn och unga inom myndighetsutövning : - En studie av kritiska incidenter

AbstractWorking with child and youth welfare is one of the most difficult challenges a social worker might face in the field of social work. Those who work with child and youth welfare are more exposed to stress and burnout than other comparable human service occupations. Research links the prevalence of stress and burnout to several key variables, such as demographics, working conditions and personality factors. In contrast, even though social workers in this field face many negative work-related problems they report a high job satisfaction. The aim of this study is to examine how uplifting and straining experiences affect social workers, who work with child and youth welfare, through the use of The Critical Incident Technique and interviews.

Bioelectromagnetics for improved crop productivity : an introductory review with pilot study of pre-sowing treatment of tomato

Various electromagnetic (EM) treatments has been investigated for their potential in improving crop productivity over the past century. There is today an increasing amount of scientists advocating EM treatments as an organically compatible method for improving plant growth and yield. However, failure to produce repeatable effects and defining causal mechanisms has made it a study of much controversy and debate. The subject requires indepth interdisciplinary knowledge, making it inaccessible for the majority of biologists, horticulturists and growers. In this combined literature review and pilot study, these issues are addressed by providing a comprehensive introductory review of the topic plant bioelectromagnetics and its potential horticultural usability.

E-böcker och bibliotek : En kritisk diskursanalys av Biblioteksbladet 2005-2011

The aim of this two years master´s thesis is to examine discourses about electronic books in relation to libraries that occur in the Swedish library journal Biblioteksbladet by using critical discourse analysis (CDA). The thesis also aims to discuss changes in the discourse practice, and discuss the relationship between discourse practice and social practice in the field of library and information science (LIS). A main point of CDA is that language is a form of social practice that helps shape social reality. Furthermore the concept of ideology, as understood with-in CDA, brings understanding to the way discursive events help reproduce and transform social relations of pow-er. The text samples span from 2005 up to and including 2011 and were examined by using Norman Fairclough´s three-dimensional conception of discourse, which allows for interpretation of text on a linguistic, discursive and social level.The result of the analysis showed that there are several different discourses about electronic books and li-braries, none of which can be said to be particularly representative.

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.

Butiksdemonstrationens mentala och beteendemässiga påverkan: - Ett fältexperiment som undersöker butiksdemonstrationens möjligheter att påverka konsumenten i butiksmiljön

The knowledge development regarding in-store marketing has shown that influencing a consumer in a store setting is a powerful tool to change the consumer?s buying patterns. However, the store as a marketing channel lacks, in many ways, conducted academic research and according to marketing theory investments into in-store marketing tend to be taken without advanced marketing consideration. As a consequence, we have chosen to generate new insights into the field of in-store marketing by studying in-store demonstrations both from a behavioral and a mental dimension. Furthermore, we have also chosen to study how different consumers with different degree of loyalty and buying patterns are influenced by an in-store demonstration.This study aimed to obtain a better understanding of in-store demonstrations through breaking down the demonstration into its core elements and from these elements construct different types of demonstrations.
