Monomer Adsorption-Desorption Processes

KE Jian-Hong,LIN Zhen-Quan,CHEN Xiao-Shuang,

中国物理快报 , 2009,
Abstract: We propose an adsorption-desorption model for a deposit growth system, in which the adsorption and desorption of particles coexist. By means of the generalized rate equation we investigate the cluster (island) size distribution in the dynamic equilibrium state. The results show that the evolution behaviour of the system depends crucially on the details of the rate kernels. The cluster size distribution can take the scale-free power-law form in some cases, while it grows exponentially with size in other cases.

Abstract: Background Phenomena of instability are widely observed in many dissimilar systems, with punctuated equilibrium in biological evolution and economic crises being noticeable examples. Recent studies suggested that such instabilities, quantified by the abrupt changes of the composition of individuals, could result within the framework of a collection of individuals interacting through the prisoner's dilemma and incorporating three mechanisms: (i) imitation and mutation, (ii) preferred selection on successful individuals, and (iii) networking effects. Methodology/Principal Findings We study the importance of each mechanism using simplified models. The models are studied numerically and analytically via rate equations and mean-field approximation. It is shown that imitation and mutation alone can lead to the instability on the number of cooperators, and preferred selection modifies the instability in an asymmetric way. The co-evolution of network topology and game dynamics is not necessary to the occurrence of instability and the network topology is found to have almost no impact on instability if new links are added in a global manner. The results are valid in both the contexts of the snowdrift game and prisoner's dilemma. Conclusions/Significance The imitation and mutation mechanism, which gives a heterogeneous rate of change in the system's composition, is the dominating reason of the instability on the number of cooperators. The effects of payoffs and network topology are relatively insignificant. Our work refines the understanding on the driving forces of system instability.
catena-Poly[[diaquazinc(II)]-μ-piperazine-1,4-diacetato-κ4N1,O1:N4,O4]

Abstract: The asymmetric unit of the title compound, [Zn(C8H12N2O4)(H2O)2]n, contains a ZnII ion residing on an inversion center, half of a centrosymmetric piperazine-1,4-diacetate ligand (L) and a water molecule. The ZnII ion is trans-coordinated by two N,O-bidentate L ligands and by two water molecules in a distorted octahedral geometry. In the crystal structure, intermolecular O—H...O hydrogen bonds link polymeric chains into a three-dimensional supramolecular structure.

Abstract: In the title compound, [Ni(SCN)(C16H32N4)]ClO4·H2O, the NiII ion is coordinated by the four N atoms of the tetraazacyclotetradeca-4,11-diene macrocyclic ligand and by the S atom of a thiocyanate anion. The perchlorate anion is rotationally disordered around one Cl—O bond between two orientations; the occupancies refined to 0.61 (4) and 0.39 (4). Intermolecular O—H...N, N—H...O and N—H...N hydrogen bonds link two cations, two anions and two solvent water molecules into a centrosymmetric cluster. The crystal packing is further stabilized by weak intermolecular C—H...O hydrogen bonds.

Abstract: In the title compound, [Co(C10H12N2O)2(H2O)2](NO3)2·2H2O, the CoII ion, located on an inversion center, is trans-coordinated by two N,O-bidentate chelating (E)-3-(dimethylamino)-1-(2-pyridyl)prop-2-en-1-one ligands and by two water molecules in a slightly distorted octahedral geometry. Intermolecular O—H...O hydrogen bonds link the cations, anions and water molecules into layers parallel to the ac plane. The crystal packing also exhibits weak intermolecular C—H...O hydrogen bonds.

Acta Crystallographica Section E , 2009, DOI: 10.1107/s1600536809025331
Abstract: The molecular skeleton of the title molecule, C9H11NOS, is essentially planar: the thiophene ring is inclined to the mean plane of the rest non-H atoms by 2.92 (3)°. The crystal packing exhibits no significantly short intermolecular contacts.
Effect of Niupo Zhibao Pellet on expression of neuronal nitric oxide synthase in brain of endotoxin-induced shock rats

Abstract: Objective: To investigate the effect of Niupo Zhibao Pellet (NPZBP) on the expression of neuronal nitric oxide synthase (nNOS) in the brain of endotoxin-induced shock rats. Methods: SD rats were randomly divided into normal control group, endotoxin-induced shock model group and NPZBP-treated group. Lipopolysaccharide (LPS) (1.5 mg/kg i.v.) and D-galactosamine (D-GalN) (100 mg/kg i.p.) were administered to the rats in endotoxin-induced shock model group, as well as to the rats in NPZBP-treated group after seven-day treatment, to induce the shock. The expression of nNOS in the brain of the rats in each of the 3 groups was measured by immunohistochemical methods. Results: In the 3 groups, nNOS immuno-positive cells distributed widely in layer Ⅱ, Ⅲ, Ⅳ of the cerebral cortex, the molecular layer of hippocampus, the polymorphic layer of the dentate gyrus, the reticular formation of brain stem, and the molecular, granular and Purkinje cell layer of the cerebellar cortex. The number of immuno-positive cells in the NPZBP-treated group was slightly higher than that of the normal control group, and signifficantly lower than that of the model group (P<0.05) in many regions of the brain, including cerebral cortex, hippocampus, brain stem and cerebellar cortex. Conclusion: NPZBP can inhibit the over-expression of nNOS in wide area of the brain in endotoxin-induced shock rats.

Abstract: Beibuwan Economical Zone of Guangxi Province has the necessary basis and conditions to develop the madicine manufacturing industry.It is significant to select products which ficilitate the development of madicine manufacturing industry from the prospective of promoting the development of the industry smoothly. The feature of selection of essential products of medicine manufacturing can be summarized as multiobjectiveness, multi-layer, fuzziness and the interaction and penetration of different objectives. Due to these characteristics, analysis is made through analytic hierarchy process (AHP) by this thesis. The paper put forward the developmental sequence of madicine manufacturing industry in Beibuwan Economical Zone of Guangxi Province by adopting analytic hierarchy process, and pointed out that, among others, the technical competence is the most influnctial factor of a company. The appropriate developmental sequence of the products selected is biological and biochemical products, medicinal chemicals, chemical medicine and preparations. This research is in favor of speeding up the development of competitive products and creating industry competition.
