Aqueous U(VI) reduction by hydrogen sulfide was investigated by batch experiments and speciation modeling; product analysis by transmission electron microscopy (TEM) was also performed. The molar ratio of U(VI) reduced to sulfide consumed, and the TEM result suggested that the reaction stoichiometry could be best represented by UO2(2+) + HS- = UO2+ S* + H+.(More)
BACKGROUND Polyunsaturated omega-3 fatty acids may beneficially influence healing processes and patient outcomes. The aim of this research was to study the clinical efficacy of fish oil enriched total parenteral nutrition in elderly patients after colorectal cancer surgery. METHODS Fifty-seven elderly patients with colorectal cancer were enrolled in this(More)
OBJECTIVE To analyze the clinical characteristics and therapeutics of elderly patients with breast carcinomas. METHODS A total of 312 patients ( ≥ 70 years old) admitted into Breast Center of Beijing Hospital from September 1997 to September 2011 were included for this retrospective study. Their clinical characteristics, treatment options and prognostic(More)
In Situ Gaseous Reduction (ISGR) using hydrogen sulfide (H2S) is a technology developed for soil remediation by reductive immobilization of contaminants such as hexavalent chromium (Cr(VI)). Deploying the technology requires us to obtain a much-improved understanding of the interactions among the contaminants, H2S, and various soil components. In this(More)
In this paper, a method based on local feature bidirectional two-dimensional principal component analysis is proposed for facial expression recognition. First of all, a facial expressional image is divided into three separate sub-blocks, from the horizontal and vertical directions we utilize bidirectional 2DPCA to extract local feature of each sub-block. To(More)
With the opening of the power industry to competition, the power system structure is changing. According to these changes, power system operation, planning, and control need modifications. Under this deregulated power market, generation companies (GENCOs) can schedule their generators to maximize their own profit without accurately satisfying system(More)
As Internet becomes popular, web personalisation for E-commerce has gained much attention. The most important strategy of web personalization is to provide the customers with appropriate information or services based on the knowledge about the customers’ preferences. This paper proposes an alternate approach based on fuzzy logic for product filtering.(More)
Batch experiments were used to evaluate the reductive immobilization of hexavalent uranium (U(VI)) by synthesized, amorphous iron sulfide (FeS) in the anoxic environment. The tests were initiated by spiking 168.0 microM U(VI) to 0.18 g/L FeS suspensions under a CO2-free condition with pH varied from 5.99 to 10.17. The immobilization rate of U(VI) was(More)
Highly uniform GaAs/GaAsP coaxial nanowires were prepared via selective-area metal organic vapor phase epitaxy. Photoluminescence spectra from a single nanowire indicate that the obtained heterostructures can produce near-infrared (NIR) lasing under pulsed light excitation. The end facets of a single nanowire form a natural mirror surface to create an axial(More)
BACKGROUND Chinese medicine (CM) has its own diagnostic indicators that are used as evidence of change in a patient's condition. The majority of studies investigating efficacy of Chinese herbal medicine (CHM) have utilized biomedical diagnostic endpoints. For CM clinical diagnostic variables to be incorporated into clinical trial designs, there would need(More)
