The aim of the project was to develop a method to investigate differences in adhesion of microorganisms to materials that contains lignocellulose. The method was tested on a gram-positive (Micrococcus lutea) and one gram-negative (E-coliJM109) bacteria.The study was begun by cultivation of the two microorganisms. The cultivation was done to calculate the generation times of the bacteria and to obtain growth curves. Cells from these cultivations were also frozen (-70ºC) and later used for inoculation.At STFI-Packforsk AB the total charge on the mass was measured and later a conductivity titration on the mass was executed as well, all to find out more about the different properties of the mass. Properties that in a later part of this study could possibly be linked to the adhesion of cells to the pulp.

The business mission of Norra Skogsägarna is to achieve a profitable forestry for the private forest owners. With this as a background it is of interest for the forest owner association to know how forest owners think about voluntary retentions, the methods of increasing production and quality and if there are differences between those who have chosen to certify their forest and those who haven?t. This kind of knowledge is of importance, to in an effectively and adjusted way, help the forest owners achieve a profitable forestry. The objective of this master thesis is to increase knowledge about private forest owners? opinions of the methods of increasing production and quality and to what extent these methods are used.

Uppsatsen utgår från ett litteratursociologiskt perspektiv, där speglingsteorin är en viktig del. Speglingsteorin innebär att man betraktar litteraturen som en spegling av samhället. Klassiska verk används till exempel som sociohistoriska källor till andra samhällen och epoker. Utgångspunkten för den här studien är att det inte enbart är de klassiska verken som utgör en sådan källa, utan att även dagens populärlitteratur kan ses som en länk till hur människor och samhälle fungerar. Den hypotes som driver uppsatsen är att litteraturen fyller en funktion för läsarna, nämligen att den tjänar som stöd och hjälp i människors liv.
