Based on the research of plant quadrate in Sangong River Basin in Xinjiang, the fitted equations were given, which could be used to estimate the aboveground biomass of typical desert plant by using the thicket characteristics such as length of crown diameter, width of crown diameter, number of basal branch, length of new branch, basal diameter (D) and plant(More)
Taking the Sangong River Basin as a typical research area, the relationships between the change of landscape pattern of desert-oasis and the dynamics of vegetation were studied in this paper, and the evolution of the landscape pattern of desert-oasis was also discussed. The results showed that the main characteristics of landscape pattern were the dynamics(More)
Four heteropoly blue complexes constructed from Keggin-type heteropoly blue molybdenum-tungsten clusters and Cu(II) ions as linkers, H2[α-SiW10Mo(V)2O40][Cu(PDA)2·H2O]2 (1), H2[α-SiW10Mo(V)2O40][Cu(DEF)3·H2O][Cu(DEF)2·2H2O]·6H2O (2), H2[α-SiW10Mo(V)2O40][Cu(DMF)3H2O]2·6H2O (3), and H4[α-SiW10Mo(V)2O40]2[CuK2(DMF)6][Na0.75K3.25(DMF)6] (4) [PDA =(More)
To evaluate the clinical significance of angiopoietin-2 (Ang-2) and vascular endothelial growth factor (VEGF) in lung cancer patients with solitary pulmonary nodule (SPN). The study enrolled 128 patients with malignant SPN, 60 patients with benign SPN, along with 40 healthy volunteers. Serum concentrations of Ang-2 and VEGF were measured by ELISA. Serum(More)
Acer miaotaiense (Sapindales: Aceraceae) is a rare and vulnerable tree species endemic to China’s Mts. Qinling and Mts. Bashan. In this study, its complete chloroplast genome was assembled and characterized from the high-throughput Illumina sequencing data. The circular genome is 156,595 bp long, and contains a pair of inverted repeat (IR) regions of 26,100(More)
Two dysprosium-containing tungstoarsenates [C(NH(2))(3)](11)[Dy(2)(Hcit)(2)(AsW(10)O(38))]·9H(2)O (1) and K(8-n)H(3-n)[Dy(3-n)K(n)(H(2)O)(3)(CO(3))(A-α-AsW(9)O(34))(A-β-AsW(9)O(34))]·22H(2)O (n = 0 or 1) (2) have been synthesized and characterized by single-crystal X-ray diffraction, elemental analyses, thermogravimetric analyses and infrared spectroscopy.(More)
Porcine reproductive and respiratory syndrome virus (PRRSV) causes great economic losses to the swine industry worldwide. Typically, an N protein-coated indirect enzyme-linked immunosorbent assay (N-coated iELISA) is used to detect PRRSV antibodies. Non-structural protein (NSP) 4 is essential to the PRRSV life cycle and contains B-cell epitopes. Yet, no(More)
A facile method is reported to construct monolithic microreactor with high catalytic performance for Knoevenagel reaction. The microreactor is based on hierarchically porous silica (HPS) which has interconnected macro- and mesopores. Then the HPS is surface modified by pyrogallol (PG) polymer. Al(NO3)3 and Mg(NO3)2 are loaded on the surface of HPS through(More)
A novel organic-inorganic hybrid of triethanolamine linked covalently with a new building block of {VMo6O25} was synthesized in aqueous solution, and the hybrid was further assembled with copper-triethanolamine complexes to form a ring-like structure. This work represents an advance in the organic functionalization of polyoxometalate performed in aqueous(More)
The reaction of Na(12)[Bi(2)W(22)O(74)(OH)(2)]·44H(2)O, Na(9)[BiW(9)O(33)]·16H(2)O, lanthanide chloride and Na(2)CO(3) in aqueous solution at a pH value of about 7.0 resulted in the three unprecedented giant lanthanide-tungstobismuthate clusters Na(x)H(22-x)[(BiW(9)O(33))(4)(WO(3)){Bi(6)(μ(3)-O)(4)(μ(2)-OH)(3)}(Ln(3)(H(2)O)(6)CO(3))]·nH(2)O {Ln = Pr(3+)(More)
