A Megasecopteron From Upper Carboniferous Strata in Spain
In 1962 Professor F.Stockmans, of the Institut Royal des Sciences Naturelles de Belgique, kindly Kitchen sent me for study two insects from Upper Carboniferous deposits in Northern Spain.One of these (no.94.837), from the Mine de Poleiro, is part of a cockroach tegmen, which cannot be placed with certainty even to family level.The other specimen (n
Bacteria transport and retention in intact calcareous soil columns under saturated flow conditions
Study of bacterial transport and retention in soil is important for various environmental applications such as groundwater contamination and bioremediation of soil and water.The main objective of this research was to quantitatively assess bacterial transport and deposition under saturated conditions in calcareous soil.A series of leaching experimen
Square Openings as Sources of Stress Concentration in Parts of Machines and Devices
In this paper the impact of square opening, as a source of stress concentration, on the distribution of stress in parts of machines and devices is considered.The fact is that these forms of the openings occur less in practice, but the knowledge of the influence of the square opening on the stress distribution, from the aspect of its size, the radiu
Different models for the Neolithisation of Albania
According to the archaeological evidence, the Neolithisation process in Albania seems to have passed through three Good Night different phases, with chronological gaps between them.The earliest phase is represented at the Vlusha site, where coarse monochrome pottery was found in the same layer as microlithic tools.The second phase can be traced bac
