Development experience of ore traffic and extraction simulation system in underground part of potash mines is reviewed. Distinctive features of suggested simulation model (combine complex extraction, using conveyor transport and transfer point in continuous ore traffic simulation) are represented. Implementation features of bundled software ”Рудопоток” are considered.

Ensifer adhaerens M78, a bacterium isolated from soil, can weather potash feldspar and release Fe, Si, and Al from rock under nutrient-poor conditions. Here, we report the draft genome sequence of strain M78, which may facilitate a better understanding of the molecular mechanism involved in mineral weathering by the bacterium.

of a jail is always of grave import. It is attributed in our Indian jails chiefly to a deficiency in the protein and alkaline constituents that enter into the composition of the prescribed jail diet, the alkaline constituents being chiefly potash salts.* These factors tend to induce a change in the composition of the blood, followed by a train of symptoms, that have special reference to the gum...

A study was undertaken to compare the anatomy of the laminar floral parts with that of the spathes and leaves of Commelina erecta L. Each flower has two types of petals and two types of sepals. In contrast to the other organs, the petals have a completely open venation system whose vein endings consist solely of modified bundle-sheath cells. Bundle sheaths of leaves and spathes, but not the flo...
