Although carbonate-carbon (C), an integral part of biochar-C, contributes to the liming properties of that material, it also interferes with the estimation of the stable organic C fraction in biochars. In this study, four methods were compared in order to quantify the carbonate-C in biochars: two direct (a titrimetric procedure and thermogravimetric analysis, TGA), and two indirect (acid treatment

The dosimetry of cone beam computed tomography (CBCT) is not fully elaborated yet, and some of these systems presents dose-area-product (DAP) values after an examination rather than, as in the case of traditional CT, the doselength- product (DLP). The purpose of this study was to provide a reproducible and straight-forward method for DLP measurements on CBCT, as well as to validate a tool for esti

Cobalt oxides are known to be active catalysts for a number of chemical reactions, but very little is known about the atomic scale processesresponsible for the activity. The research presented in this thesis is focused on obtaining an atomic scale understanding of the chemistry of wellcharacterizedcobalt oxide model catalyst surfaces consisting of pristine and defective CoO and Co3O4 thin films wi

This article examines the economic incentives for Europeans to migrate to the so-called 'white man's grave' of West Africa. Ignorance and coercion have been proposed as explanations for migration to high mortality areas. We use data on the Royal African Company and their European employees on the Gold Coast during the period 1707-1740. We found that the employees received a premium above the wage

Photomultiplier tube (PMT) nonlinearities relevant for single shot high-speed lifetime phosphor thermometry were investigated by simulating decay curves with a light emitting diode (LED) at repetition rates between 1 Hz and 10 kHz. The PMT gain, LED decay time, and background radiant flux were also varied to investigate their impact on the measured decay time error. Errors in the measured decay ti

The increase in electric vehicles has led to more vehicles of this kind being involved in accidents. Since there is a risk of a delayed initiation of thermal runaway in these cases, many countries have recommendations for safety distances from crashed vehicles to buildings. This report is a part of theeffort to develop similar guidance for Sweden, which was initiated by the Swedish Civil Contingen

Synchrotron radiation sources have greatly contributed to the progress in many fields of science. The development of the storage ring technologies have made possible to obtain very low emittance electron beams, which together with the use of undulators allow to guide a very high photon flux into a very small beam size required by the experiments. Development of sources has been accompanied with eq
