Abstract This paper examines the relationship between democracy and economic growth in 30 Sub-Saharan African countries. As our proxy for democracy we first use the democracy index constructed by Freedom House and then check the sensitivity of our findings using, as an alternative proxy for democracy, the Legislative Index of Electoral Competitiveness (LIEC). We find support for the Lipset hypo...
Macroscopic, periodic, dark and bright patterns are observed on sections of elephant tusk, in the dentin part (ivory). The motifs-also called Schreger pattern-vary depending on the orientation in the tusk: on sections perpendicular to the tusk axis, a checkerboard pattern is present whereas on sections longitudinal to it, alternating stripes are observed. This pattern has been used to identify ...
Low cycle isothermal mechanical fatigue testing of a eutectic alloy 63Sn/37Pb was carried out in a systematic manner over a wide range of frequencies (10–1 Hz) and temperatures (240 to 150°C) with the total strain set at different values (1–50%). The low cycle fatigue behavior of the eutectic solder was found to be strongly dependent on test temperature and frequency. If the Coffin–Manson model...
The Western clawed frog, Xenopus tropicalis, is a highly promising model amphibian, especially in developmental and physiological research, and as a tool for understanding disease. It was originally found in the West African rainforest belt, and was introduced to the research community in the 1990s. The major strains thus far known include the Nigerian and Ivory Coast strains. However, due to i...
We describe a 27-year-old patient with Coffin-Lowry syndrome with severe community pneumonia, septic shock and respiratory failure. We summarize both the mechanical ventilatory assistance and the hospitalization period in the intensive care unit.
