To match the relentless pursuit of three research hot points - efficient solar utilization, green and sustainable remediation of wastewater and advanced oxidation processes, solar-mediated thermo-electrochemical oxidation of surfactant was proposed and developed for green remediation of surfactant wastewater. The solar thermal electrochemical process (STEP), fully driven with solar energy to el...

This paper outlines statistical database system (SDB) security from a viewpoint of the protection against the threat of statistical inference. The SDB security techniques discussed are classified into nonperturbative, perturbative, camouflaging, and hybrid approaches based on protection requirements. This paper represents a first step in the development of a comprehensive classification system ...

The lubricity of drilling fluid resistant to high-temperature over 200 ℃ is still one the technological breakthroughs. In this study, graphene modified with sodium dodecylbenzene sulfonate (SDBS) was selected as a lubricant. Our results show that fluids have high stability after aging at 240 °C assistance SDBS/graphene. Excitingly, tribological performance test revealed SDBS/graphene exert exce...

Chin proposed an audit scheme for inference control in statistical databases (SDBs) which can determine whether or not a query will lead to the compromise of an SDB. As Chin points out that the dynamic updates of an SDB are prohibited in this scheme because, otherwise, the time and storage requirements will become infinite. The restriction limits the use of this scheme since many SDBs need to b...

Knowledge discovery in databases (KDD) is an important task in spatial databases since both, the number and the size of such databases are rapidly growing. This paper introduces a set of basic operations which should be supported by a spatial database system (SDBS) to express algorithms for KDD in SDBS. For this purpose, we introduce the concepts of neighborhood graphs and paths and a small set...

Models of binary star interactions have been successful in explaining the origin of field hot subdwarf (sdB) stars in short period systems, but longer–period systems that formed via Roche– lobe overflow (RLOF) mass transfer from the present sdB to its companion have received less attention. We map sets of initial binaries into present–day binaries that include sdBs and main– sequence stars, dis...

The effect of three chemical formulationstwo surfactants, Sodium Lauryl Sulfate (SLS) and Sodium Dodecyl Benzene Sulfonate (SDBS) and a builder Sodium Tripolyphosphate (STPP) on two aquatic plants – Azolla pinnata and Hydrilla verticillata was studied at various concentrations for a period of five months, from November to March. It was observed that while the detergents favoured the growth of p...

The coupling of structural fluctuation and the dynamics of associated water molecules of biological macromolecules is vital for various biological activities. Although a number of molecular dynamics (MD) studies on proteins/DNA predicted the importance of such coupling, experimental evidence of variation of hydration dynamics with controlled structural fluctuation even in model macromolecule is...

The combination of surfactant enhanced soil washing and degradation of nitrobenzene (NB) in effluent with persulfate was investigated to remediate NB contaminated soil. Aqueous solution of sodium dodecylbenzenesulfonate (SDBS, 24.0 mmol L-1) was used at a given mass ratio of solution to soil (20:1) to extract NB contaminated soil (47.3 mg kg-1), resulting in NB desorption removal efficient of 7...
