17 tomato cultivars inoculated with larva nematodes were used in this paper to investigate their resistance to root knot nenatodes. The results showed that gall index of LA1312, 3601, HA4402, LA1007 were higher than other tomato cultivars. Compared with control ‘Caihong101’, root activity of LA0655 was higher, and the lowest root activity was observed in 3601, whose gall index was the highest among...
Using coconut-water as main culture medium, carboxymethyl cellulose -bacterial cellulose (CMC-BC) materials were obtained by Acetobacter xylinum through adding CMC as substitute carbon source in static cultivation. When 0.6% (w/v%) CMC was added into the medium, the yield of dried film reached 10.41g/L compared to 4.73 g/L in the control. The FT-IR spectra of the CMC-BC showed the absorption of a...
Chongqing district is located in the southwest part of China. For the reason of the Three Gorges Reservoir Area Chongqing district receives a lot of attention from the Chinese government and international societies. In the study, using normalized difference vegetation index(NDVI)as an indicator of vegetation activity, seasonal trends of vegetation activity and their dynamic in Chongqing were explored...
In the last decade, the role of NO in plants has received much attention. Due to its multifunctional activities in plants, NO is now being considered as a new candidate plant hormone. However, it is not very clear that the physiological mechanism of exogenous NO alleviates salt effects in vegetable plants. Therefore, an experiment was conducted to study the effects of exogenous NO on physiological...
According to the concentrations of Cr, Cu, Zn, As, Cd and Pb in the latosol f rom the West of Hainan Island, the integrated pollution effect of heavy metals of these latosol is evaluated by the technique of single factor index and Hakanson ecological risk.The results show that the average concentration of Cr, Cu, Zn, As, Cd and Pb is 39.245 mg/kg, 36.937 mg/kg, 57.997mg/kg , 17.606mg/kg, 0.198mg/kg,...
The safety evaluation of the urban public transport is safety management, foundation of decision. This text combines the actual conditions of our country, construct urban public transport evaluation index system of traffic safety. Utilize the subjective and objective method to confirm the weight of each index according to the characteristic of the index, adopt the gray model to carry on comprehensive...
The study on spatial evolution of urban landscape pattern can provide a technical and decision-making support for the city's sustainable development. In the paper, based on the two remote sensing images in 1985 and 2002, the land utilization information of two different periods was gained with the auxiliary of the GIS and RS and the changes in land use were analyzed. In addition, quantitative analysis...
totally 77 physicochemical properties of amino acids are collected and used as the structural descriptors of peptide sequences, and based upon it several statistical models are constructed by using stepwise multiple regression (SMR) and partial least squares (PLS) regression. In both MRL and PLS model, the obtained correlation coefficients r are all above 0.95. And then the predictive capability of...
In this thesis, it made spleen deficiency modeling dog by subcutaneous injection of reserpine. The clinical symptom, body weight and the part indicator of liver and antioxidant function were observed. And there was a study about effect of Sijunzi Tang on the observed indexes. The results showed that the body weight in dogs, the activity of alanine aminotransferase (ALT) and aspartate aminotransferase...
Weld bead surface quality has an important effect on the quality of prototyped products .In the paper, hierarchy analytical theory, combined with the experiment, is employed to determine the weld bead surface quality synthesis evaluation weight coefficient of bead uniformity, bead continuity and spatter. The membership degree tables of bead uniformity, bead continuity and spatter are created by using...
This paper investigates the technical performance of the high viscosity modified asphalt added the domestic TBS high viscosity modifier under different content. Test results indicate that all indexes of the high viscosity asphalt which added 15% domestic TPS are best, through the tests such as penetration test, softening point test, toughness test, tenacity test, 60°C dynamic viscosity test, 135°C...
How to screen active components of herbal drugs is still a hot topic of pharmacologists and pharmaceutical chemists. The main aim of the study was to establish a strategy to tract the active components in early stage based on the fact, that a compound (component) can not take systematic effect without binding to a biomolecule of organism. Affinity constants (KD or KD) and relative affinity indexes...
In order to investigate the overall characteristics of the transcript profiles associated with these puzzling biological effects. We used the Agilent Rice Oligo Microarray to learn the molecular mechanism in rice responding to ion-implantation. The analysis of the genechip array shows that there were 982 transcripts expressed differentially (fold change > 2 and P value < 0.05) including...
The objective of this study was to introduce a new high-performance diameter distribution function. The long-term repeated measurement data sets, consisted of 150 diameter frequency distributions from Chinese fir (Cunninghamia lanceolata) plantations in the southern China, were used. R distribution had presented a more accurate simulation than three-parametric Weibull function. The parameters p, q...
The regional site selection of industrial plant (RSSIP) can hardly be done unless the comprehensive ranking of the cities and towns in the region have been determined. Thus, a new method for confirming the compound weight, with the help of which the comprehensive ranking can be more exactly confirmed, is proposed in the paper. Firstly, the objective weights of different indexes are gained through...
A strain of the high-accumulating bacterium P5 was isolated from the pond sludge. The bioreactor of immobilized cell was made up with cinder grain as the carrier. The experimental results show that under the optimal operating conditions, the phosphorus removal rate was 99.30% and the removal rate of CODCr was 92.14% to simulated wastewater with 20mg/L phosphorus (PO43−-P) for 30 minutes and the phosphorus...
The high temperature damage index series of 25 stations were calculated from 1960 to 2007, and these series were consisted of a matrix. After doing EOF to the matrix, two meaningful eigenvector fields were got, and therefore two main patterns about the spatial distribution of the high temperature damage to Rice in Jiangsu were found: the whole distribution pattern and the south-north distribution...
Objective To study the prescription and preparation technology of Prunella ethanol extract dispersible tablets. Methods Take disintegration time as indexes, the prescription and preparation technology were optimized by an orthogonal design. The hardness, suspended uniformity, dissolution were investigated and preliminary stability were tested through accelerated test. Results The optimum prescription...
The paper discussed the change process of cultivated land and spatial difference in Qingdao city nearly 60 years according to the statistical data. By means of the social economic statistical software - SPSS18.0, the paper studied the driving forces on the cultivated land changes of Qingdao using Principal Component Analysis (PCA). The results indicated that the change of cultivated land was influenced...
It is important to low-carbon buildings development that value engineering is a management technique and scientific method developed, firstly was put forward at twentieth century. Combined with the characteristics of low-carbon buildings and value engineering analysis, this paper put forward the theory of low-carbon value and calculation formula for that provide reference ideas for the development...
