Död ved i ett referensvattendrag
The purpose with this study is to find out how much dead wood we can expect us to find in a Russian reference river and compare with studies from Swedish streams. Dead wood are an important structure for the biodiversity in forest streams, studies have shown that population of trout can increase with up to 300 % when the amount of dead wood are increasing from 0 to 8 ? 16 LWD (Large woody debris)/100 m2. Dead wood are also an important structure for the stream character, formations of dams and pools which are important habitats and reproduction areas for salmon and brown trout.
The study where taken place in tributaries to the Russian river Varzuga in the North West part of Russia outside Murmansk. Varzuga has low impact of human activity and is considered to be a reference river to rivers in northern Sweden.
Beskrivning av systemfunktioner i kärnkraftverk med hjälp av objektorienterat modelleringsverktyg
In order to facilitate design and maintenance of such a large and complex site as a nuclear power plant, all system functions must be described in a stringent way. In the past, these descriptions consisted of text documents and logical diagrams, but today there are an increasing number of object-oriented programs available on the market which might be used for this purpose. This Master Thesis has made a closer study of one of these programs named Rational Rose. The principal of the program is to facilitate software design and development, not to create models of plants. However, using the program the same way as developing software, specifying actors then gradually extend the model with use cases, use cases diagrams etc, the same methods can be used when modelling plants.
Identifiering av gallringsbehov med hjälp av flygburen laserskanning :
Thinning is one of the most important silvicultural activities in middle aged forests, partly to minimize damages and partly because it leads to earlier harvesting revenues and increases the value of the remaining trees. There are many different indices used to describe stand density and thereby the need of thinning in forests today. Studies have shown that forest variables can be estimated with high accuracy using airborne laser scanning and it is likely that the method could also be used to estimate forest density indices. In this study, the possibility of using the forest density index ?H² to determine and map priorities for thinning operations for a forest area was examined.
From a rough to a fair way of organizing : En analys av genomförandeorganisationen i Svenska Golfförbundet

Ledarskapsstilar : En studie över skillnader i ledarskapsstilar mellan Sverige och Grekland
The recent globalization has to some extent reduced the importance of specific cultures and instead creates a focus on the variation these different cultures provide. Under these circumstances the leader must adapt his leadership to face these new circumstances. The organisations today have to face these new leadership challenges which the global expansion brings. This is a prerequisite for organizations if they want to succeed and be more competitive in a more demanding environment.There are still big differences between the business cultures. There are also differences in the companies? home arena, between groups in the society and all the way down on a family level.

EU i nyheterna : En diskursanalys om EU och EU:s anseende i det svenska medieutbudet
The purpose of this essay is to analyze the EU discourse in the Swedish media. The questions that the analysis seeks to answer are; what image of EU is portrayed in the Swedish media? To which degree does the EU discourse fulfill media?s ?news values?? And what are the potential effects of the discourse on EU?s reputation? After several demarcations, I chose 8 articles form Sweden?s four largest newspapers to base the analysis on. The theoretical and methodical structure behind this analysis is the theories and practices of Fairclough?s critical discourse analysis. Added to the theoretical structure are also theories about reputation and theories about news values. The method used in the analysis is a modified version of Fairclough?s three-dimensional model of critical discourse analysis.

Abdominellt ultraljud av vuxna nötkreatur : en praktisk guide
Ultrasound is a diagnostic aid often overlooked by the veterinary practicioner who works with farm-animals. However, it?s use increases, particulary for breeders where ultrasound has long been used to evaluate ovaries and to diagnose pregnancy or disturbances in reproduction. There is much knowledge in how to examine ovaries and uterus by transrectal ultrasound, but when it comes to doing ultrasound of other organs in the abdomen the knowledge is more limited.
Cows are very large animals, so it is not possible to examine everything inside the abdomen with ultrasound, simply because the ultrasound beam has a limited penetration. There is also lots of gas inside the gastro-intestinal tract of a cow, mainly in the large intestine and the rumen, and that makes it impossible to examine the organs behind the gas since the ultrasound waves are reflected when reaching the soft tissue-gas interface.
