Growth chamber study on the impact of CO_2 concentration and radiant intensity on Salix psammophila photosynthetic rate

Abstract: CO_2 in the atmosphere is a necessary substance for plant photosynthesis, and solar radiation is a necessary energy for plant photosynthesis. CO_2 concentration in the atmosphere is increased by human activities, which results in changes in temperature, water and radiation. Studying the impact of changes in CO_2 concentration, soil water, radiation and other eco-environmental factors on plants has been one of the foci in global change studies. S. psammophila is one of the dominant shrubs in Mu Us sandland. ...
Temperature Dependent Motion of a Massive Quantum Particle  [PDF]

Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.37083
Abstract: We report model calculations of the time-dependent internal energy and entropy for a single quasi-free massive quantum particle at a constant temperature. We show that the whole process started from a fully coherent quantum state to thermodynamic equilibrium can be understood, based on statistics of diffracted matter waves. As a result of thermal interaction between the particle and its surroundings, the motion of the particle shows new feature.

Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.312241
Abstract: The time-dependent entropy of a single free quantum particle in the non-relativistic regime is studied in detail for the process started from a fully coherent quantum state to thermodynamic equilibrium with its surroundings at a finite temperature. It is shown that the entropy at the end of the process converges to a universal constant, as a result of thermal interaction.

Abstract: The summer rainfall over the middle-lower reaches of the Yangtze River valley (YRSR) has been estimated with a multi-linear regression model using principal atmospheric modes derived from a 500 hPa geopotential height and a 700 hPa zonal vapor flux over the domain of East Asia and the West Pacific. The model was developed using data from 1958?92 and validated with an independent prediction from 1993?2008. The independent prediction was efficient in predicting the YRSR with a correlation coefficient of 0.72 and a relative root mean square error of 18%. The downscaling model was applied to two general circulation models (GCMs) of Flexible Global Ocean-Atmosphere-Land System Model (FGOALS) and Geophysical Fluid Dynamics Laboratory coupled climate model version 2.1 (GFDL-CM2.1) to project rainfall for present and future climate under B1 and A1B emission scenarios. The downscaled results provided a closer representation of the observation compared to the raw models in the present climate. In addition, compared to the inconsistent prediction directly from different GCMs, the downscaled results provided a consistent projection for this half-century, which indicated a clear increase in the YRSR. Under the B1 emission scenario, the rainfall could increase by an average of 11.9% until 2011?25 and 17.2% until 2036?50 from the current state; under the A1B emission scenario, rainfall could increase by an average of 15.5% until 2011?25 and 25.3% until 2036?50 from the current state. Moreover, the increased rate was faster in the following decade (2011?25) than the latter of this half-century (2036?50) under both emissions.

Abstract: The title compound, C30H48O3, was extracted from the plant Dracocephalum rupestre Hance. The molecule contains five fused cyclohexane rings and one five-membered lactone ring. Intermolecular O—H...O hydrogen bonds between the hydroxyl and carbonyl groups link the molecules into chains along [010]. The absolute structure has not been determined.

Acta Crystallographica Section E , 2010, DOI: 10.1107/s1600536810038328
Abstract: The title compound, C16H14Cl2N2O3·H2O, displays a trans conformation with respect to the C=N double bond. The dihedral angle between the two benzene rings is 4.98 (12)°. Intramolecular O—H...N and O—H...O hydrogen bonds occur. The crystal structure is stabilized by intermolecular O—H...O and N—H...O hydrogen bonds. In addition, there are π–π interactions between the chemically distinct benzene rings of inversion-related molecules [centroid–centroid separation = 3.715 (1) ].

Abstract: The title compound, C17H16Cl2N2O3·H2O, displays a trans conformation with respect to the C=N double bond. The dihedral angle between the two benzene rings is 30.77 (5)° and there is one intramolecular N—H...O hydrogen bond. In the crystal, molecules are linked by hydrogen bonding to the water molecules of crystallization, which acts as both an acceptor and a donor, into a three-dimensional network.
