Исследование свойств техногенных грунтов калийного производства

The paper contains the results of experimental investigations of physical and mechanical properties of technogenic slime soil. The experimental data have made it possible to obtain mathematical dependences of moisture, adhesion, internal friction angle, filtration coefficient on time usage of slime soil as construction material for slime storage dikes.Представлены результаты экспериментальных исследований физико-механических свойств техногенных шламовых грунтов. В результате обработки опытных данных получены математические зависимости влажности, сцепления, угла внутреннего трения, коэффициента фильтрации от времени эксплуатации шламового грунта в качестве строительного материала ограждающих дамб шламохранилищ

THE INFLUENCE OF COLD PLASMA ABLATION ON HUMAN AND ANIMAL KNEE JOINT CARTILAGE

Cold plasma ablation is widely used in knee arthroscopy during past decade. We studied its influence on knee joint cartilage in a human in vitro and in dogs in vivo. Histomorphological study was performed in a human cartilage right after the exposition of CPA. In animals MRI and morphological study were performed after three months of exposition of CPA. It was shown that CPA was able to cause immediate changes of collagen in the human cartilage in vitro and also death of chondrocytes in animal in vivo after three months. The depth of necrosis of the cartilage in animal was significantly deeper the subhondral bone
