Monoclinic tungsten oxide (WO3) nanoplates were synthesized via a two-step simple process: acid precipitation at room temperature to prepare WO3.H2O and annealing high (400 500 oC) in ambient air obtain WO3 nanoplates. The effect of on physical properties (morphology, oxygen deficiency, crystallinity, optical properties, photocatalytic activity) was studied. At both two studied temperatures, all samples have the stable monoclinic structure visible light-range bandgap, but morphology activity...

User identifications are in searching Online Social Networks (OSN) to find identical users among different social sites many data sources (data integration, enrichment, information retrieval,...). However, these user-unique attributes difficult obtain due privacy issues. It is hard identify across multiple OSNs online. This paper has presented user's identification order develop engine for user identification. The proposed approach designed by while accommodating (OSN). Experimental results...

Native to Southeast Asia, the Sunda pangolin (Manis javanica) is critically endangered largely because of poorly regulated wildlife trade, consumptive practices, and use in traditional Chinese medicine. Efforts rescue rehabilitate animals confiscated from illegal trade are complicated by a general lack knowledge surrounding normal health disease processes unique species. To provide clinical reference intervals for states pangolins, biochemical parameters were determined rescued individuals...

Accurate prediction of two-phase parameters is essential for the development, operation and safety nuclear power plants. In this paper, ANN-based model has been developed, implemented with PDE (Partial Differential Equation) solver in case study frictional pressure drop prediction.

This paper present a preliminary thermal-hydraulics analysis of AP1000 containment following loss coolant accident events such as double-end cold line break (DECLB) or main steam (MSLB) using MELCOR code. A this type will produce rapid depressurization the reactor pressure vessel (primary system) and release initially high water into followed by much smaller highly superheated steam. The liquid flash rapidly pressurize building. performance passive cooling system for removal condensation on...

The non-condensable gas effect is a primary concern in some passive systems used advanced design concepts, such as the Passive Residual Heat Removal System (PRHRS) of AP1000, APR1400, AES-2006, Containment Cooling (PCCS) AP1000 design, and Isolation Condensation (ICS) ESBWR design. accumulation inside condensing tubes can significantly reduce level heat transfer which affects removal capacity accident condition impacts plant safety. objective present work to assess analysis capability two...

The accurate prediction of void fraction parameter in subcooled boiling flow is very important for nuclear safety since it has significant influences on the mass rate, onset two-phase instability, and heat transfer characteristics a reactor core. Many different models empirical correlations have been established over variety input conditions; however, this classical approach could lead to unsatisfactory due uncertainties model forms. To cope with these limitations, Artificial Neural Network...

The most widely studied LOCA (Loss of Coolant Accidents) is a rupture cold leg pipe causing the Reactor Cooling System to depressurize first, with different break sizes corresponding change in trigger signal from Instrument and Control (I&C System) such as pressure, temperature, power, pressure vessel water level, etc. different. Therefore, response nuclear power plant varies considerably size break. To mitigate consequence given size, it necessary design emergency core coolant systems...

This article deals with current trends in combat vehicle maintenance and the possibility of using tribodiagnostic on internal combustion engines during their life cycle. Since having to repair when there is an engine failure, up now, has been developed by monitoring technical condition engine, especially oil analysis, which helps predict damage advance, thereby correcting damaged engine. Maintenance work shortened, reduced costs, increased machine reliability. The use a physicochemical...
