The exact timing, route, and process of the initial peopling of the Americas remains uncertain despite much research. Archaeological evidence indicates the presence of humans as far as southern Chile by 14.6 thousand years ago (ka), shortly after the Pleistocene ice sheets blocking access from eastern Beringia began to retreat. Genetic estimates of the(More)
The paper presents a mathematical model and simulation results of dynamic characteristics of the single-phase capacitor induction motor for different values of the capacitor capacitance and moment of inertia at no-load and nominal load conditions. The model has been used to study the effect of some machine parameters on the start-up and load performance of(More)
Marine cyanobacterial mats were cultured on coastal sediments (Nivå Bay, Øresund, Denmark) for over three years in a closed system. Carbonate particles formed in two different modes in the mat: (i) through precipitation of submicrometer-sized grains of Mg calcite within the mucilage near the base of living cyanobacterial layers, and (ii) through(More)
