The use of algae as a feedstock for the production of advanced biofuels has tremendous potential because of its short growth cycle, high productivity, lack of competition for agricultural lands, ability to use a variety of water sources and recycle CO2 and nutrient emissions, and compatibility with existing fuels chains with minimum process changes. However, to make significant contributions to bi
We consider the problem of seeking the maximum of a scalar signal using a swarm of autonomous vehicles equipped with sensors that can take point measurements of the signal. Vehicles are not able to measure their current position or to communicate with each other. Our approach induces the vehicles to perform a biased random walk inspired by bacterial chemotaxis and controlled by a stochastic hybrid
In the wake of the deterioration of relations between modern Russia and Poland, the Katyn memorial has become a scene for the contestation of historical memory. In order to play down the 1940 executions of Polish military officers in Katyn, the Russian government has granted belated official recognition to 8,000 victims of Stalinism in the Smolensk region. After being brushed under the carpet in t

Aim: Grass-yellow butterflies (Eurema) are a group of pantropical Pieridae distributed throughout Asia, Australasia, Africa and the New World. However, little is known about their diversification, including the biogeographic mechanism(s) explaining their circumglobal distribution. We present the first densely sampled, time-calibrated phylogeny and biogeographic reconstruction of grass-yellows to c

This article outlines an experimental and numerical study of moisture in concrete subjected to air, water or sealed curing. For this purpose columns of eight qualities of concrete were studied at 3 different ages each over a period of 450 days. Parallel studies of hydration, internal relative humidity, self-desiccation and strength were carried out. Finally the article presents an analysis of the
