Influence of the high-power ion-beam irradiation of a hydroxyapatite target on the properties of formed calcium phosphate coatings

The physical-mechanical of properties of biocompatible calcium phosphate coatings deposited onto titanium and silicon substrates from erosion materials, which are generated by irradiating hydroxyapatite (synthetic and natural) targets by means of the high-power pulsed ion beam of a Temp-4 accelerator, are investigated. A calculation technique for predicting the rate and energy efficiency of deposition using pulsed ion beams is proposed. Their characteristics are analyzed as applied to the formation of calcium phosphate coatings

Problems of Population Provision with Water Supplies in the Khabarovsk Territory during the Flood Period

Since the first day of the emergency, organized was the surveillance over the water supply provision for the population of the Khabarovsk Territory with a view to decrement of the high water aftermaths. Laboratory control of the water quality was performed in the amplified enhanced mode. Based on the results of the control, necessary measures were operatively undertaken. In accordance with the current legislation procedures, proposals for the improvement of water supply quality, hyper chlorination, and application of alternative ways of water supply were submitted to the local government authorities. The population was warned about consumption of guaranteed quality drinking water only. The problem of fresh water provision in the period of rainfall floods was addressed by means of bottled water supplies delivery to the remote waterlogged areas of the region. Control over the centralized and non-centralized water supply sources, implementation of sanitary-and-antiepidemic activities made it possible to prevent the emergence of acute enteric infection, virus hepatitis A, and other infectious disease outbreaks
