Novel Arsenic Nanoparticles Are More Effective and Less Toxic than As (III) to Inhibit Extracellular and Intracellular Proliferation of Leishmania donovani by Sudipta Chakraborty, Kaushik Bhar, Sandip Saha, Rajarshi Chakrabarti, Anjali Pal, Anirban Siddhanta

“…As-NPs inhibited the in vitro growth, oxygen consumption, infectivity, and intramacrophage proliferation of L. donovani parasites at a concentration which is about several fold lower than that of As (III). Moreover, this antileishmanial activity has comparatively less cytotoxic effect on the mouse macrophage cell line. …”

Variation of Pore Water Pressure in Tailing Sand under Dynamic Loading by Jia-xu Jin, Hong-zhi Cui, Li Liang, Shi-wang Li, Ping-yi Zhang

“…The results revealed four stages in the increase of the tailing pore water pressure under dynamic loading, namely, a slow increase, a rapid increase, inducement of structural failure, and inducement of complete liquefaction. A lower frequency and smaller amplitude of the vibration were found to increase the time required to achieve a given pore water pressure in dense tailings. …”
