STUDY OF CLAY SHALE SLOPES ALONG THE PANAMA CANAL. REPORT 2: HISTORY, GEOLOGY, AND MECHANICS OF DEVELOPMENT OF SLIDES IN GAILLARD CUT. VOLUME 1: TEXT The sliding associated with construction of the Panama Canal began with early French excavation and has continued with intermittent activity until ...
Tiegel and Klebs in 1864 demonstrated that anthrax-infected blood, if filtered through a clay candle (bacterial filter), lost its infectivity, while the deposit on filter remained infective[15]. These observations in absence of culture of the organism strongly supported the concept that the ...

Settlement on the thickly forested clay soils of the lowlands did not becomefeasibleuntil the 8th centuryce, with the invention of the heavy-wheeled plow. One of the most significant technological inventions of the Middle...

The studied samples show three subgroups of results with different water filtration properties, which depend mainly on pore formation and connections between them. Low values of k are found in local weak zones of the rock mass, which may indicate admixtures of clay minerals that fill the pore ...
in clay-size particles usually cannot be drained by subsurface improvements. It is essential to consider soil properties to a depth of 1.5 to 1.8 metres (5 to 6 feet), because the layer in the soil that transmits water the slowest controls the design, and subsurface improvements may be ...
Wild bees, as the most common pollinators, provide crucial ecosystem services in both natural and anthropogenically modified habitats. In urban areas, protective measures are undertaken more and more often to improve their living conditions (construction and installation of bee houses) and to increase...
