Sulfur in coal and pulp have been characterized using pyrolysis–gas chromatography with a sulfur-selective flame photometric detector (Py–GC/FPD). The samples (50–150 µg) were pyrolyzed at temperatures between 300 and 1400°C usually followed by a combustion in oxygen at high temperature (>1000°C). The main sulfur-containing products were low-molecular compounds such as H2S, COS, SO2, CH3SH and CS2

This is the third volume in Norstedt's new standard history of Sweden, spanning over the period 1350-1600, i.e. from the Black Death to the Vasa era. Of key importance in Dick Harrison's part of the book (the first half) is the plague epidemics of the late Middle Ages, the political culture of the Kalmar Union and the peasant upheavals in the fifteenth century.
The degradation of different polyethylenes, LDPE, LLDPE, and HDPE, with and without antioxidants and at different oxygen concentrations in the polymer granulates have been studied in extrusion coating processing. The degradation was followed by On Line Rheometry, Size Exclusion Chromatography, Surface Oxidation Index measurements, and GC-MS Chromatography. The degradations starts in the extruder w
A study of foreign places present in Swedish feature films during the period 1980-2010, asking what functions foreign settings (and cultures, identities etc) serve within stories belonging to different genres.

Recently, there has been considerable interest in the internal reforming reactions of solid oxide fuel cells (SOFCs) using methane or natural gas via. The internal reforming and electrochemical reactions appear in the porous anode layer, and may lead to inhomogeneous temperature and gas species distributions according to the reaction kinetics. A three-dimensional calculation method has been furthe
The work presented in this thesis can be divided into the three following fields of investigation: First of all the ionization model developed in this thesis is meant to simulate the thermal ionization process or the so-called second peak. Equilibrium assumptions have been adopted for the modeling of the thermal ionization, in which Saha’s equation was derived for singly ionized molecules. The inv
Popular Abstract in English Plants harvest sunlight to fix air carbon dioxide into a form which is the fundamental source of energy for other organisms such as animals. The domestication of crop plants and traditional breeding practices has resulted in increased yield and nutritional value of crops. This comes at a cost of loss in genetic variability that is required by living organisms to adapt tPotato is one of the major food crops and its yield is severely affected by late blight disease caused by Phytophthora infestans. P. infestans has the ability to manipulate plant defence signalling by secreting effector molecules causing so called effector triggered susceptibility. Some plants can recognize these effectors via resistance proteins that reactivate plant defence and lead to effector
Makasae is a non-Austronesian / Papuan language spoken by a population of some 70,000 in the newly independent state of East Timor. Because of its long history of occupation and civil war, the nation’s languages are so far sparsely documented. The present work is the first Makasae grammar description to be published in English. Makasae is largely isolating in structure, and its grammar has in man
Syftet med denna artikel är att beskriva några ledstjärnor för en kreativitetsfrämjande lärandemiljö och exemplifiera hur dessa har tillämpats på en universitetskurs i psykologi. Åtta betydelsefulla aspekter - framvaskade från forskningslitteraturen - introduceras som en utgångspunkt för lärare att arbeta med, nämligen 1) att skapa ett öppet klimat, 2) flexibilitet i struktur, metod och attityd, 3
