Alternative sources of hydrocarbon raw materials

open access: yesResults in Engineering
Oil-bituminous rocks (OBR), with reserves reaching up to 860 billion tons, are considered an alternative raw material of the future. Bitumen is seen not only as a substitute for oil but also as a raw material for road construction, used for the disposal ...

Effect of a humid environment on the surface structure of RuO2(110)

open access: yes, 2003
Combining density-functional theory and thermodynamics we compute the phase diagram of surface structures of rutile RuO2 (110) in equilibrium with water vapor in the complete range of experimentally accessible gas phase conditions.

Advancing pharmacometrics in Africa—Transition from capacity development toward job creation

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 407-419, March 2025.
Abstract Trained pharmacometricians remain scarce in Africa due to limited training opportunities, lack of a pharmaceutical product development ecosystem, and emigration to high‐income countries. The Applied Pharmacometrics Training (APT) fellowship program was established to address these gaps and specifically foster job creation for talent retention.

Spectromicroscopy Analysis of Chicken Egg Shells

open access: yesX-Ray Spectrometry, EarlyView.
ABSTRACT Chicken egg shells, taken from farm and backyard eggs of different suppliers from different regions in Brazil were collected for chemical/structural analysis, in order to try to find if there is a relation between egg shells composition and the type of production (farm or backyard), the egg shell color and the region of production.

First-principles kinetic Monte Carlo simulations for heterogeneous catalysis, applied to the CO oxidation at RuO2(110)

open access: yes, 2005
We describe a first-principles statistical mechanics approach enabling us to simulate the steady-state situation of heterogeneous catalysis. In a first step density-functional theory together with transition-state theory is employed to obtain the ...

One‐Sidedness and the Inferior Function in Coriolanus and Timon of Athens

open access: yesJournal of Analytical Psychology, EarlyView.
Abstract For both Jung and Shakespeare, one‐sidedness is the fundamental tragic trait. Jung proposed that as an individual develops, they inevitably associate their identity with certain modes of perception and interaction, and that this leads to psychological polarization.
