A computer model based on minimization of the free energy, capable to predict contact angles and spreading transitions between Wenzel and Cassie mode for drops placed on surfaces with different topography were implemented in matlab. Simulations were compared with experiments documented in the literature. These showed that reported transitions between Cassie and Wenzel mode can be explained by minimization of the free energy. In this report, a study on the possibility of constructing water Repellent paper surfaces with a combination of treatment with octadecyltrichlorosilane and topography changes, is included..

The report is a comparative study between spruce plantations where 4 plants are treated with deer Repellents and 4 plantations are untreated. The study aims to provide a base for the Forest Society's future decisions regarding the use of wildlife-Repellents.  The report indicates that wildlife-Repellents work reasonably well for its purpose, the treated stocks were virtually untouched during the planting year and next year while the untreated stocks have been heavily grazed during these years.  Growth difference between grazed plants and ungrazed plants found to be virtually non-existent (0, 01 m) of the treated stocks and 0, 07 m in the untreated plants. Because of the growth differences are so small between grazed and no grazed plants, it seems like the treatment of deer-Repellent are unnecessary. Unless you know in particularly that the area has a specific problem whit severe deer-grazing..

The calculations in this thesis are evaluating the profit as a consequence from treating young stands of pine in Sweden with birch bark extract, BBE. Treatment is to be done with the object to lower or fully reduce the moose browsing on pine. The study is made in three versions. The results from each version separately will follow below. Version I.: The size of the moose population is in no way affected by the reduced resources of food as a consequence of large scale treatment with BBE on pine. Results show profit at a 3 percent level of interest with the exception of treatment program with more than 4 treatments all together and with the exception of Västerbottens Län with an early first treatment. Version II.: The population of moose decrease from 10 to 5 individuals per 1000 ha as a consequence from large scale treatment with BBE on young pine stands.

Syfte: Vårt syfte med föreliggande arbete är att, mot bakgrund av existerande forskning, beskriva försvarsstrategier vid fientliga företagsförvärv. Vi avser även att undersöka ett antal fientliga förvärvserbjudanden och därigenom utreda vilka försvarsstrategier som förekommer och i vilka kombinationer dessa används. Målsättningen är även att göra en bedömning av vilka försvarsstrategier som är mest effektiva vid fientliga angrepp. Metod: Vi har främst använt oss av en kvalitativ metod. Uppsatsen kan delas in i tre olika metodiska faser.
