An assessment for sustainable developing capability of integrated agricultural regionalization in China

Based on the provincial units evaluation, this paper makes an assessment for sustainable developingcapability of the integrated agricultural regionalization in China. At first, an index system of agricultural sustainabledevelopment in China is built up, which includes 5 supporting subsystems of agricultural resources, agricultural develop-ment, environment and ecosystem, rural society, sciences-education and management. We selected 95 factors on provin-cial level as basic indexes. Second, a relative assets/debt assessing method is used to gain relative net assets values(relative superiority) of every provincial unit, which are as supporting data for assessment. We also overlaid the Administra-tive Divisions Map of China and the Map of Integrated Agricultural Regionalization of China by Geography Information Sys-tem (GIS) to gain the area units of assessment. Third, according to the relative coherence principle of regionalization,we transform administration units to natural units through homogenizing all provincial relative net assets values in everyagricultural assessing unit. After making order and grade, we complete the sustainable developing capability assessmentto integrated agricultural regionalization in China. The assessing outcome shows that the total sustainable agricultural develop-ing capability of China is not high. Only about 1/3 in number or in area has reached the level of agricultural sustainabledevelopment. The relative net assets values exists a reducing trend from East China to West China. It needs a long periodand great efforts to realize sustainable agricultural development over all China. Finally, there is a discussion to the studymethod.
The S~2NS Digraphs and the Cycle Linear System of a Digraph

It is known that the study of the qualitative properties of a matrix A (which depend only on the sign pattern of A) can be turned into the study of the graph theoretical properties of the signed digraph S(A). The underlying digraph of the signed digraph of a strong sign nonsingular matrix (abbreviated S~2NS matrix) with a negative main diagonal is called an S~2NS digraph. In the study of S~2NS digraphs, the minimal forbidden configuration (or MFC for short) plays an important role. Three (classes of) MFS's were constructed by Thomassen, Brualdi and Shader, and Shao. In this paper, we show that a digraph D is an S2NS digraph if and only if its "cycle linear system" is solvable. This simplifies a parallel result obtained by Shao and Hu. As an application of the result, a graph theoretical characterization for a digraph to be an S~2NS digraph is given. At the end of the paper, we construct infinitely many new MFCs to show that for each even number k(k>0), there are basic MFCs with k terminal components (here, with no loss of generality, we assume that the number of the initial components of a digraph is no less than that of its terminal components throughout the following).
THE DYNAMICS OF FERTILITY IN C-K MODEL WITH ENDOGENOUS FERTILITY

Based on the Cass-Koopmans Model with endogenous fertility given in the paper [1-4], the fertility dynamics is discussed in this paper. It is proved that the first quadrant of the k,c plane is separated into two parts by a increasingly differentiable curve.The fertility increases with time on the upper half and decreases with time on the lower half. The fertility decreases along one arm of the economic growth path on which the per capita capital and per consumption increase and increases along the other arm of the economic growth path on which the per capita capital and per person consumption decrease under the condition 0 ＜θ≤α. This confirms the empirical finds that negative relationship between the economic growth and population growth.
Modified High-order Upwing Method for Convection Diffusion Equation

In this paper, we study the high-order upwind finite difference method for steady convection-diffusion problems. Based on the conservative convection-diffusion equation, a high-order upwind finite difference scheme on nonuniform rectangular partition for convection-diffusion equation is proposed. The proposed scheme is in conversation form, satisfies maximum value principle and has second-order error estimates in discrete H~1 norm. To illustrate our conclusion, several numerical examples are given.

目的研究纤维蛋白溶解参数(D-二聚体)是否能够成为颅脑损伤病人判断伤情及预后的新指标.方法选用30例单纯颅脑损伤病人进行研究,探讨血浆中D-二聚体浓度水平与病人预后的关系.结果当血浆中D-二聚体浓度＞6 μg/mL,无论病人入院时意识是否清醒,89%的病人均死亡;D-二聚体浓度＜2 μg/mL时,病人均能恢复良好.结论病人入院时血浆中D-二聚体的浓度可作为判断颅脑损伤病人预后的一种指标,应用该指标在入院时即可判断病人的伤情及预后,并在入院时也能分辨出进展型颅脑损伤病人.
Boundary Value Problems for Singular Second-Order Functional Differential Equations

Positive solutions to the boundary value problem, are obtained by applying the Schauder fixed point theorem, where w(x) is a continuous function defined on [0, 1] and f(x, y) is a function defined on (0, 1)2(0, X), which satisfies certain restrictions and may have singularity at y=0. The result corrects and improves an existence theorem due to Erbe and Kong [1].
Interannual and Decadal Variability of Landfalling Tropical Cyclones in the Southeast Coastal States of the United States

The interannual variability of the At lantic tropical cyclone (TC) frequency is well known. Separately,recent studies have also suggested that a much longer, multidecadal (40-60 year) trend might be emerging from the recent increase in Atlantic TC activity. However, the overall structure of the intrinsic frequencies (or temporal modes) of Atlantic TC activity is not yet known. The focus of this study is to systematically analyze the intrinsic frequencies of Atlantic TC activity using hurricane and tropical storm landfall data collected along the southeast coast (SEC) of the United States. Based on an Empirical Mode Decomposition (EMD) analysis of the frequency of landfall TCs along the SEC from 1887-1999, we have found that Atlantic TC activity has four primary, temporal modes. The interannual and multidecadal modes reported in the published literature are two such modes. After identifying all primary modes, the relative importance of each mode and its physical cause can be analyzed. For example, the most energetic mode is the interannual mode (2-7 year period). This mode is known to be associated with the 2-7 year El Nino / La Ni na cycle. The average number of annual landfalling TCs along the SEC decreased by 24% during El Nino years, but did not show significant increase during weak and moderate La Nina years. However, intense La Nina years were generally associated with more than average landfalling TCs along the SEC. The effects of El Nino and La Nina also became more significant when only hurricanes were considered. The significance of the effects of El Nino and La Nina on landfalling TCs and hurricanes in different US southeast coastal states showed significant differences.
Teleconnections: Summer Monsoon over Korea and India

This study investigates the relationship between the summer monsoon rainfall over Korea and India, by using correlation analysis and Singular Value Decomposition (SVD). Results reveal that summer monsoon rainfall over Korea is negatively (significant at the 99% level) correlated with the rainfall over the northwest and central parts of India. In addition, coupled spatial modes between the rainfall over Korea and India have been identified by the SVD analysis. The squared covariance fraction explained by the first mode is 70% and the correlation coefficient between the time coefficients of the two fields is significant at the 99% level, indicating that the coupled mode reflects a large part of the interaction between the summer monsoon rainfall over Korea and India. The first mode clearly demonstrates the existence of a significant negative correlation between the rainfall over the northwest and central parts of India and the rainfall over Korea. Possible mechanisms of this correlation are investigated by analyzing the variation of upper-level atmospheric circulation associated with the Tibetan high using NCEP/NCAR Reanalysis data.

An example is given as an application.
A New Holographic Entropy Bound from Conformal Field Theory at the Killing Horizon

A new holographic entropy bound is obtained by using conformal field theory at the Killing horizon. The entropy bound is tighter than the well-known bounds, such as the Bekenstein, Bekenstein-Mayo and 't Hooft bounds. The result shows that the entropy of a system decreases when quantum effects are included. Therefore, the quantum effect will increase the degree of order of the system.

Effect of diet supplementation with l-carnitine on hepatic catabolism of l-alanine in rats

AIM: To investigate the effects of chronic supplementation with l-carnitine (LCT) on hepatic catabolism ofl-alanine. METHODS: Two groups of male adultWistar rats were used: 1 ) supplemented with LCT ( 1.2mmol@ kg- 1@ d- 1 ) dissolved in the drinking water (LCTgroup) and 2) control group (COG) without LCT supplementation. After one week of LCT supplementationlivers from 24 h-fasted rats were perfused in situ and theproduction of glucose, urea, pyruvate, and l-lactate froml-alanine (5 mmoL/L) were measured. RESULTS:LCT decreased the production of glucose and urea froml-alanine. In agreement, pyruvate and l-lactate production from l-alanine were decreased. However, thesupplementation with LCT did not show any significanteffect on hepatic glucose production from pyruvate (5mmol/L) and l-lactate ( 2 mmol/L). CONCLU-SION: LCT supplementation decreased the conversion ofl-alanine to pyruvate. However the ability of the liver toconvert pyruvate to glucose was not affected by LCTtreatment.

神经科研究中设计类型的辨析方法

在定量资料的假设检验中,误用统计方法最常见的原因是忽视资料所对应的设计类型.有些人根本没有这方面的概念,只要看到观测结果是定量的资料,就认准一定要用t检验.仅从设计类型角度看,适合选用t检验的设计类型只有3种,即单组设计、配对设计和成组设计[1].这3种设计资料的t检验公式稍有区别,不应盲目套用.
Inclination of Broad Line Region in Narrow Line and Broad Line Seyfert 1 Galaxies

The sizes of the Broad Line Region (BLR) of some Seyfert 1 galax-ies and nearby quasars can be determined by the reverberation mapping method.Combining with the observed FWHM of Hβ emission line and assuming that themotion of BLR clouds is virialized, the black hole masses of these objects have beenestimated. However, this method strongly depends on the poorly-understood geom-etry and inclination of the BLR. On the other hand, a tight correlation between theblack hole mass and the bulge velocity dispersion was recently found for both activeand nearby inactive galaxies. This may provide another method, independent of theBLR geometry, for estimating the black hole mass. Using this method for estimatingthe black hole mass and combining with the measured BLR size and FWHM of Hβemission line, we derived the BLR inclination angles for 20 Seyfert I galaxies underthe assumption that the BLR is disk-like. The derived inclination angles agree wellwith those derived previously by fitting the UV continuum and Hβ emission lineprofiles. Adopting a relation between the FWHMs of [OⅢ]λ5007 forbidden line andthe stellar velocity dispersion, we also estimated the BLR inclinations for 50 nar-row line Seyfert 1 galaxies (NLSls). We found that the inclinations of broad LineSeyfert 1 galaxies (BLS1s) are systematically greater than those of NLS1s, whichseldom exceed 30. This may be an important factor that leads to the differencesbetween NLS1s and BLS1s if the BLR of NLS1s is really disk-like.

Analysis of corrosion behavior of LY12 in sodium chloride solution with wavelet transform technique

Wavelet transforms(WT) are proposed as an alternative tool to overcome the limitations of fast Fourier transforms(FFT) in the analysis of electrochemical noise(EN) data. The most relevant feature of this method of analysis is its capability of decomposing electrochemical noise records into different sets of wavelet coefficients(distinct type of events), which contains information about the time scale characteristic of the associated corrosion event. In this context, the potential noise fluctuations during the free corrosion of commercial aluminum alloy LY12 in sodium chloride solution was recorded and analyzed with wavelet transform technique. The typical results show that the EN signal is composed of distinct type of events, which can be classified according to their scales, i.e. their time constants. Meanwhile, the energy distribution plot(EDP) can be used as “fingerprints” of EN signals and can be very useful for analyzing EN data in the future.
Effects of Cu( II) or Zn( II) on photodegradation of some toxic organic compounds in wastewater by using TiO2 as catalyst

The effects of Cu ( I ) or Zn ( H ) on the photo-catalytic degradation of some organic chemicals in water, such as acetone, phenol, dyes, and tea saponin were studied.  Dyes in wastewater from a textile factory can be effectively degraded by photo-catalysis with TiO2 and ultraviolet light or sunshine, but the reaction rate could be slowed down if copper or zinc salt exists in the solution.
Quantum chemical calculations on structure of Mo_8O_(26)~(4-)

Two possible structures of Mo8026" were optimized using the Polak-Ribiere method of Molecular Mechanics Optimization and the termination condition is RMS (Root-mean-square) gradient of 0.42 kj/mol. Based on the calculations of the molecular dynamics, Lengevin dynamics and Monte Carlo dynamics simulation, the structure models of Moa O_(26)~(4-) with the lowest energy were acquired respectively according to the energy of the systems calculated using the ZIDO/1 and PM3 methods. The total energy, energies of some frontier molecular orbitals and atomic charges of Mo_8O_6 were computed at the HF/3-21G and HF/STO-3G levels. The calculation results show that the contortion of the structure with eight Mo06 is smaller than that of the structure with six Mo06 and two Mo04. The total energies of the two structures are nearly equal be-cause the contortion of Lhe structure with six MoO6 and two Mo04 would make the exclusion force decreased.
Physico-chemistry in distillation process of BiCl3-HCl-H2O system

The gas-liquid equilibrium and evaporation behaviors of HCl and H20 in the distillation process of the BiCl3-HC1-H2O ternary system were investigated. With increasing content of BiCl3 , the quasi-azeotropic point moves toward the low acidity and high temperature. The evaporation law of HCl and H2O in low-acidity BiCl3 solution was summarized. The residue phases were studied as well. The results show that the residue phases vary with the distillation temperature, namely BiCl3 and BiCl3  xHCl at low temperature and BiCl3 and BiOCl exist at higher temperature. The causes for the formation of different residue phases were discussed.
Bioleaching of marmatite in high concentration of iron

Bioleaching of marmatite with a culture of Thiobacillus ferrooxidans and Thiobacillus thiooxidans in high concentration of iron was studied, the results show that the zinc leaching rate of the mixed culture is faster than that of the sole Thiobacillus ferrooxidans, the increasing iron concentration in leaching solution enhances the zinc leaching rate. The SEM analysis indicates that the chemical leaching residues is covered with porous solid layer of elemental sulfur, while elemental sulfur is not found in the bacterial leaching residues. The primary role of bacteria in bioleaching of sphalerite is to oxidize the chemical leaching products of ferrous ion and elemental sulfur, thus the indirect mechanism prevails in the bioleaching of marmatite.
Effect of hydroxamic acid starch on reverse flotation desilicate from diasporic bauxite

It is important to depress diaspore effectively in order to remove silicates from diasporic bauxite. A new water soluble polymer hydroxamic acid starch ( HA-starch) was prepared. The effects of the product on the diaspore and kaolinite flotation were investigated and its reactive mechanism was studied by zeta potential measurement and FTIR. The results show that HA-starch can depress diaspore while make positive effect on kaolinite flotation at low pH value (pH below 6). The flotation recovery of diaspore was sharply decreased with the increase of concentration of HA-starch. The chemical ad-sorption of HA-starch on the surface of diaspore was revealed.
Mechanical properties and creep resistance of Mg-Li composites reinforced by MgO/Mg_2Si particles

The mechanical properties at room temperature and the creep resistance at room and elevated temperatures of Mg-Li alloy and composites reinforced by MgO/Mg_2Si particles were studied. The (Mg-8Li) eutectic binary alloy is of better mechanical properties than those of the others. The strength, elastic modulus and hardness of composites are much higher than those of matrix alloys. The elongation of the composites is lower than that of the matrix, but it keeps a high level(＞4%) and is much higher than that of the Mg-Li base composites reinforced with Al_2O_3 and SiC fibres. The creep resistance of the composites is significantly increased in comparison with the matrix, such as the creep rate of the composite is respectively 10% and 2% of that of matrix at room temperature and at 160℃. The creep mechanism is also discussed.
Thermal decomposition kinetics of antimony oxychloride in air

The DTA and XRD techniques were employed to study thermal decomposition mechanism of antimony oxyhloride SbOCl in the air. The thermal decomposition reaction occurs in four steps, and the former three steps as: SbOCl (s) →Sb_4O_5Cl_2(s) + SbCl_3 (G) → Sb_8O_(11)Cl_2(s) + SbCl_3(g) → Sb_2O_3(s) + SbCl_3(g). The forth step is the oxidation of Sb_2O_3 by air,  Sb_2O_3(s) + O_2+→Sb_20)4(s). The activation energy and the order of the thermal decomposition reaction of antimony oxychloride in three steps presented in DTA curves were calculated according to Kinssinger methods from DTA curves.   The  values  of  activation  energy and  the order are  respectively  91.97kJ/mol,   0.73   in  the  first step, 131.14kJ/mol, 0.63 in the second step and 146.94kJ/mol, 1.58 in the third step.
Structure of medium-range order in molten Al-Fe alloy

The molecular-dynamics (MD) simulation was carried out to investigate the structure of medium-range order (MRO) of a liquid Al5Fe2 alloy. Prepeak is observed in the structure factor S{ Q) , which is considered as the signature of MR0. Results from MD simulation and experiment agree well with each other, which proves reliability of the simulation. It is found from the calculated Ashcroft-Langreth structure factors that there exists strong interactional force between atom Al and Fe, which results in the great concentration fluctuation, i. e. the chemical order, in the liquid Al5Fe2. Both the chemi-cal order parameter, a , and the Bhatis-Thornton(BT)structure factors indicate the preference for unlike-neighbor bonds. It is seen from the low-() domain of S(Q) and the concentration-concentration structure factor Scc (Q) that the prepeak mainly comes from the first peak of SCC(Q). The structural model, which reflects the characteristic of MRO, is also con-structed .
Surface analysis, hydrogen adsorption and electrochemical performance of alkali-reduce treated hydrogen storage alloy

The hydrogen storage alloy powders (MlNi_(4.0)Co_(0.6)AV_(0.4),  Ml= rich-La mischmetal) were treated in a hot 6 mol/L K0H+ 0.02 mol/L KBH4 solution, the surface compositions and chemical states of the treated and untreated al- loys were analyzed by XPS and EDX, the hydrogen adsorption on the surface of these alloys was evaluated by thermal desorption spectroscopy (TDS), the effects of the surface treatment on the electrochemical performances of the alloy elec-trodes were investigated. The results show that the hydrogen adsorption is greatly strengthened by the surface modifica-tion, and hence leads to marked improvement in the electrocatalytic activity,  the treated alloy exhibits higher exchange current density and lower apparent activation energy for the hydrogen electrode reaction than the untreated alloy
