Based on the summary of the methods of coal demand forecasting, this article conducts the empirical analysis of the impact of electric power production on the demand of coal of China through Granger causality test and simultaneous equations model and predicts the trend of Chinese coal demand. Then the article puts forward some suggestions to the policy of strengthening coal demand management.
Laser-induced fluorescence spectroscopy is a widely-used medicinal spectral technique that has been used on the diagnosis of tissues and cells. In this paper, we measured the auto-fluorescence of serum of lung cancer patients and healthy people using the technique of laser-induced fluorescence spectroscopy. Principal component analysis and discriminant analysis were used to analyze the data of fluorescence...
In this study, source model for solving biomagnetic inverse problem is developed with a new method, where vortex components along with the flow component of the equivalent source is considered. The model is an aggregation of a single current dipole and a magnetic dipole. The single current dipole denotes the flow component while the magnetic dipole is an abstract of the vortex component of the biomagnetic...
Lung cancer has the highest mortality rate because of the difficulty in early diagnosis. Surface enhanced Raman spectroscopy (SERS) can detect the bio-fluids at a molecular level, thus is capable of predicting lung cancer at an early stage. In this paper, we used SERS on saliva to detect its components for the diagnosis of lung cancer. Principal component analysis combined with linear discriminant...
Pu-er tea pile-fermentation is a high temperature process. Thermophiles during the pile-fermentation of Pu-er tea have not been reported up to now. This paper was isolated 13 thermophiles during the pile-fermentation of Pu-er. Then each strain was inoculated into the piles of Pu-er tea and simulated thermophilic pile-fermentation, with testing tea polyphenols, theaflavin, thearubigins and theabrownines...
This study isolated 8 thermophilic fungi from pile-fermentation of Pu-er tea, and identified as Rhizomucor pusillus (4 strains), Aspergillus fumigates (2 strains), Rhodotorula glutinis (1 strains), Thermomyces lanuginosus (1 strain) by 18S rDNA homology analyses. The strains were added into pile-fermentation of Pu-er tea to observe the effects on the fermentation. The results showed that the strains...
Glutathione peroxidase is a mammalian selenoenzyme that catalyzes the reduction of hydroperoxides and play crucial roles in scavenging reactive oxygen species in living organisms. Native glutathione peroxidase have poor solubility and limited cellular accessibility. Morevoer, it is difficult to prepare using traditional recombinant DNA technology. Peptides with an Arg-Gly-Asp (RGD) sequence have shown...
The s-lap is a novel gene discovered and cloned from the porcine retinal pigment epithelial cells which show earlier signs of apoptosis induced by visible light damage. However, its function is still unclear. To clarify the relationship between s-lap and apoptosis, we investigated the expression, localization of s-lap/GFP fusion protein and its effect on cell cycle in 293T cells. The plasmid expressing...
In order to optimize the extraction conditions of total flavonoids from Suaeda salsa, on the basis of single factor investigations, the effects of three independent variables (ethanol concentration, extraction temperature, and liquid to solid ratio) on the extraction rate of total flavonoids from S. salsa were evaluated. The optimal extraction conditions for total flavonoids extraction were determined...
In this study a kind of alkai-soluble polysaccharide in Tremella fuciformis was extracted and purified for the first time. Its structure and antioxidant activities were evaluated. It showed that alkai-soluble polysaccharide of Tremella fuciformis (ASTP) was with a molecular weight of 32.9 kD. The main monosaccharides in ASTP were β-type pyran configuration. ASTP showed higher antioxidant activity...
Peroxidases play a critical role in the anti-oxidant enzyme protection system of plants accordingly, we assumed that wintersweet (Chimonanthus praecox), as a multi-resistant plant adapting to a variety of stressful conditions, should contain certain special peroxidase. In this study, a putative peroxidase cDNA containing a ORF (CpPOD) was cloned by screening the full-length cDNA library of wintersweet...
The optimal technological requirements for flavonoids extracting by ultrasonic wave from rice plant (variety ASD7) and the insecticidal effect of the flavonoids on brown planthopper (BPH) were investigated. Four main factors, including ethanol concentration, ratio of liquid to solid, ultrasonic power and extracting time were firstly analyzed by singlefactor analysis, and followed by orthogonal experiments...
The purpose of this study is to compare the effect of non-essential amino acids and essential amino acids on in vitro maturation and development of reconstructed embryos of porcine oocytes. The oocytes were divided into four groups, the IVM medium of porcine were added 1% the essential amino acids, 1% non-essential amino acids, both 1%essential and nonessential amino acids, And non amino acids as...
The efficiency of producing porcine transgenic cloned embryos is still low due to lower developmental competence compared to in vivo-fertilized/cultured embryos. This phenomenon may correlates with poor culture condition. Energy substrate in culture medium play an important role in optimizing culture condition. This study pertain to investigate the effect of replacing pyruvate and lactate with glucose...
This paper presents the design of a web-based application for relieving stress, VReST. The application is an image-based virtual reality system which was built based on the concept of guided image therapy, one of technique used by therapist to induce relaxation in the patent. Often in traditional guided image therapy session, patient was asked to visualize an image of a beautiful and calm place and...
The objective of this paper is to present a novel method based on detect mobile robot for risk evaluation under coal mine, the approach is based on rough set and neural network theories, the data of the evaluation chart were reduced by using rough sets reduction function and then the reduced data were transferred to the BP neural network as training data. This method provides a new concept for the...
