Abstract: Approaches to the artificial impoundment and theoretical design of sedimentation retention basin are reviewed with particular attention to best management practice(BMP) to control agriculture and surface runoff. Sediments retention basins are the small version of farm pond used where a criteria of farm pond is not met. Such basin traps the pollutants and suspended solids prior to entry into streams and lakes. The study is focused with special reference to the assessment and control of non point source pollution(NPSP) from the sub basin area of Tai Lake in the Xishan County of Wuxi City of China. The author suggested two different approaches to conduct this study including theoretical design for sedimentation retention basin and computation of flow, sediment transport and deposition during the artificial impoundment of retention basin for BMP's utilization. Theoretical design will provide a useful function as a first line defense against the movement of sediments and transport of pollutants into the Tai Lake while the assessment of sediments deposition will help to make its proper use and periodic cleanup.
10,11,12,13-Tetrahydro-4,5,9,14-tetraazadibenz[a,c]anthracene–benzene-1,4-dicarboxylic acid (2/1)
Chun-Bo Liu,Jian Wang,Xiu-Ying Li,Guang-Bo Che
Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808027785
Abstract: In the title adduct, 2C18H14N4·C8H6O4, the centrosymmetric 1,4-benzenedicarboxylic acid molecule makes two O—H...·N hydrogen bonds to adjacent 10,11,12,13-tetrahydro-4,5,9,14-tetraazadibenzo[a,c]anthracene (TTBT) molecules. Aromatic π–π stacking interactions occur between TTBT rings [centroid–centroid distance = 3.570 (3) ], leading to a two-dimensional supramolecular structure in the crystal.
Bis(1,10-phenanthroline-5,6-dione-κ2N,N′)silver(I) 2-hydroxy-3,5-dinitrobenzoate
Shen-Tang Wang,Guang-Bo Che,Chun-Bo Liu,Xing Wang
Acta Crystallographica Section E , 2012, DOI: 10.1107/s1600536811053785
Abstract: In the cation of the title salt, [Ag(C12H6N2O2)2](C7H3N2O7), the AgI atom is coordinated in a distorted tetrahedral geometry by four N atoms from two 1,10-phenanthroline-5,6-dione ligands, while the 3,5-dinitrosalicylate anion has only a short contact [2.847 (6) ] between one of its O atoms and the AgI atom. The dihedral angle between the two 1,10-phenanthroline-5,6-dione ligands is 58.4 (1)°. There is an intramolecular O—H...O hydrogen bond in the 3,5-dinitrosalicylate anion.

Abstract: The complete molecule of the title compound, [MnCl2(C18H10N4)2], is generated by crystallographic twofold symmetry with the Mn atom lying on the rotation axis. The Mn coordination geometry is a distorted cis-MnCl2N4 octahedron, arising from two N,N′-bidentate dipyrido[3,2-a:2′,3′-c]phenazine (DPPZ) ligands and two chloride ions. In the crystal structure, neighbouring mononuclear units pack together through π–π contacts between the DPPZ rings [shortest centroid–centroid distance = 3.480 (2) ], leading to a chain-like structure along [001]. C—H...Cl hydrogen bonds complete the structure.

Abstract: 湖泊湿地资源开发利用与保护临界(简称“湿地临界”)的经济学准则是指湿地开发利用的边际净收益应不低于边际净损耗,也就是当生态损失发生特大变化,超出净收益,或者直接经济效益下降,小于净损耗时的湿地利用规模。其核心是生态服务功能之间的相容性分析及其效益的经济评估,即与开发利用功能相容的服务效益作为净收益的组成部分,与开发利用功能不相容或有条件相容的服务作为净损耗的组成部分。宝应湖围网养蟹的净收益包括围网养蟹、调节小气候和吸收二氧化碳的效益,净损耗包括供水、净化水质、调蓄洪水、生物多样性保育、科研教育、休闲娱乐的效益。经计算得到,宝应湖围网养殖的年净收益为37 304元/hm2,净损耗为16 222元/hm2,ΔE值为21 082元/hm2,因此认为,在目前的社会经济水平下,宝应湖围网养蟹的利用方式尚未超出湖泊湿地开发利用临界的经济学准则,仍具有一定的开发利用潜力。

Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536809016778
Abstract: The title compound, 3C14H12N2O2·C3H7NO, was synthesized by reaction of benzoyl chloride with hydrazine hydrate under microwave irradition. The asymmetric unit comprises three 1,2-dibenzoylhydrazine molecules and one dimethylformamide molecule. The 1,2-dibenzoylhydrazine molecules are linked by pairs of N—H...O hydrogen bonds into chains propagating along [010].

Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808027177
Abstract: In the title compound, [Co(C6H2N2O4)(C14H8N4)(H2O)]n, the Co atom is bonded to one N,N′-bidentate pyrazino[2,3-f][1,10]phenanthroline (Pyphen) ligand, one N,O-bidentate pyrazine-2,3-dicarboxylate (PZDC) dianion and one water molecule in a distorted octahedral mer-CoN3O3 geometry. The CoII atoms are bridged by the PZDC dianions, forming an infinite one-dimensional chain running along the b axis. Adjacent chains pack together through π–π stacking interactions [centroid–centroid separations = 3.498 (4) and 3.528 (4) ], and O—H...O and O—H...N hydrogen bonds involving the water molecule complete the structure.

Acta Crystallographica Section E , 2008, DOI: 10.1107/s1600536808027153
Abstract: In the title compound, [Fe(C6H2N2O4)(C18H10N4)(H2O)]n, the FeII ion adopts a slightly distorted octahedral mer-FeN3O3 geometry, arising from one N,N′-bidentate dipyrido[3,2-a:2′,3′-c]phenazine ligand, one N,O-chelating pyrazine-2,3-dicarboxylate dianion and one water molecule. An O-bonded symmetry-related dianion completes the coordination of the metal. The bridging dianion results in a one-dimensional polymeric chain. Aromatic π–π stacking interactions between ligands [centroid–centroid separations = 3.528 (2) and 3.741 (2) ] and O—H...O and O—H...N hydrogen bonds link the chains together, leading to a three-dimensional supramolecular network.
