The comminution processes are complex and there has thus far been no, previously published, efficient way to calculate the cost per product and metric ton. The proposed model has been adapted to fit the currently investigated process of crushing and screening (C&S). Deriving from the original model, the proposed new model is presenting the result in cost per metric ton of raw material. It has

The new species Candelaria fibrosoides is described. It is known from one locality in Ayacucho in Peru where it was found growing at high altitudes on shrubs and cacti in open pasture land. The new species is superficially similar to C. fibrosa but differs in having 8-spored asci and a thallus with an ecorticate lower surface.

Popular Abstract in Swedish Tillväxtintentioner och kommunikativ praktik Strategiskt entreprenörskap vid företagsutveckling Denna avhandling fokuserar på entreprenörers “will and skill”, d.v.s. viljan och den kunskap och färdighet som entreprenören har vid start och utveckling av ett företag. Med vilja avses entreprenörens tillväxtintention och med kunskap och färdighet avses kommunikationen mellThis thesis focuses on the “will and skill” of individuals who take part in activities of running a business. The aspect of “will” is studied in terms of growth intentions and the aspect of “skill” is studied in terms of communicative practices. The overall purpose is to explore how entrepreneurs think and talk about growth and how they act in their communicative practices to express their growth

I this thesis, optical studies of InAs quantum dots (QDs) in GaAs and InP are presented. The electronic structure of these zero dimensional structures, grown in the Stranski-Krastanow growth mode, was studied by photoluminescence spectroscopy (PL), junction space-charge techniques (JSCT) and photoconductivity (PC) measurements. For the InAs/GaAs system we present single-dot photoluminescence spec

Between 1996 and 2002, 16 patients with rheumatoid arthritis and failed total ankle prosthesis underwent tibiotalocalcaneal fusion using retrograde intramedullary nails. The functional outcome was evaluated using the AOFAS scoring system and the patients were also asked about their satisfaction. Radiographs were obtained for all 16 cases minimum 1 year after surgery. Thirteen of the 16 ankles wer

The purpose of this paper is to show how eye-tracking methodology can be used to study ‘inner space’; both from a theoretical point of view – the existence (or not) of internal image representations – as well as from an applied point of view – the usage of mental imagery in thinking and reasoning. First, we introduce the reader to the mental imagery debate. Second, we summarize studies on mental i

A high-bandwith robot-workpiece interaction requires a stiff robot without resonances in the frequency range of operation. In this article, the compliance dynamics of the Gantry-Tau parallel kinematic robot were identified using subspace-based identification and physical modeling. Measurements were performed both with a camera vision system developed and with a laser tracker. Although promising si

Atmospheric aerosol particles have substantial influence on climate and air quality. However, the anthropogenic influence on the atmospheric aerosol is still poorly known. This limits the understanding of past and future climate changes. Additionally, both epidemiological and toxicological studies indicate adverse health effects of inhaled aerosol particles. In order to study the effect of atmosph

Popular Abstract in Swedish Populärvetenskaplig sammanfattning Personer som är deprimerade löper större risk att begå självmord än de som har andra psykiska störningar. Studier har visat att cirka 6-15% av alla patienter med affektiv sjukdom begår självmord. Vidare har det visat sig att cirka hälften av alla människor som tar livet av sig har haft en depression. Man har därför sökt efter riskfaktSuicide in Severe Depression. A Longitudinal Case-Control Study. The present thesis is based on a case-control study of suicide victims with a severe depression/ melancholia. All patients admitted to the Department of Psychiatry 1956-1969 who received this diagnosis on a multiaxial schedule (1206 patients) were followed up in two sessions to 1984 and to 1998 concerning suicide and general mortali
