A total of 195 subjects, including 141 exposed workers and 54 farmers, were recruited in China to evaluate the usefulness of chromium (Cr) in erythrocytes as a biomarker of exposure to CrVI. The levels of Cr in red blood cells (RBC) were remarkably elevated even in a group of workers routinely exposed to CrVI as low as 5-15 microg m(-3) and showed a(More)
This paper presents a method of estimating regional distributions of surface air temperature (Ta) and surface vapor pressure (ea), which uses remotely-sensed data and meteorological data as its inputs. The method takes into account the effects of both local driving force and horizontal advection on Ta and ea. Good correlation coefficients (R2) and root mean(More)
With the development of IT technology and the emergence of Internet, Electronic Trading(ET) has been widely used in international financial market. In this paper, first introduce the background of ET application, then depict the actual situation of ET development in HongKong China as an example, and analysis the impact of Electronic Trading on market(More)
Authentication and key agreement protocol is designed to provide pair of parties communicating over an insecure network with a secure session key. However, most of the existing authenticated key agreement protocols are not designed for protecting privacy. A mutual authentication key agreement protocol based on CPK technology and the improved Elliptic Curve(More)
OBJECTIVE To explore the effect of emodin-8-O-β-D-glucoside (EG) on cell apoptosis and expression levels of Bcl-2 family proteins in human ovarian cancer SKOV3 cells. METHODS SKOV3 cells were cultured and divided into two groups (control group and experimental group). Cell viabilities were determined by the methyl thiazolyl tetrazolium (MTT) method;(More)
To achieve multi-channel acquisition of the signals with different sampling rates, the authors of this paper design a multi-channel signal acquisition module with field programmable gate array (FPGA) as the core. This module adopts FPGA chip as core controller of the system, for the purpose of controlling A/D converter, multi-channel analog switch gating,(More)
The partitioning of available energy between sensible heat and latent heat is important for precise water resources planning and management in the context of global climate change. Land surface temperature (LST) is a key variable in energy balance process and remotely sensed LST is widely used for estimating surface heat fluxes at regional scale. However,(More)
