Soil temperature is a major effective factor on the soil and plant biological *** can affect soil temperature and thereby induces a temperature effect on plant growth,which may result in an economic increase due to higher yield and plant nutrition.A ?eld experiment was carried out to investigate the effects of three irrigation strategies including full irrigation(FI),partial root-zone drying(PRD) and de?cit irrigation(DI) on soil temperature and the consequent results on the grain yield and N uptake of maize(Zea May L.).Soil temperature was measured by time domain re?ectometry(TDR) sensors during the 2010 growing *** treatments were applied from 55 to 107 d after *** PRD treatment caused soil temperature to be in a favorable domain for a longer period(for over 60% of the measuring dates) as a consequent result of water movement to deeper soil layers compared with the other treatments;the PRD treatment also reduced soil temperature at deeper soil depths to below the maximum favorable soil temperature for maize root growth,which resulted in deeper root penetration due to both water availability and favorable soil *** to the FI treatment,the PRD treatment increased root water uptake by 50% and caused no signi?cant reduction in total N uptake,while this was not observed in the DI treatment partially due to the negative temperature effect of DI on plant growth,which consequently affected the water and nutrient uptake.A longer vegetation period in the PRD treatment was observed due to higher leaf N concentrations and no signi?cant reduction in maize grain yield occurred in the PRD treatment,compared with those in the FI *** on the results,having 15.2% water saving during the whole growing season,the PRD irrigation would positively affect soil temperature and the water and nutrient uptake as a consequent,which thereby would prevent signi?cant reduction in maize grain yield.

In this paper, the problem of determining the largest possible set of symmetries for an important nonlinear dynamical system： the two-dimensional damped Kuramoto-Sivashinsky （（21）） DKS ） equation is studied. By applying the basic Lie symmetry method for the （217）） DKS equation, the classical Lie point symmetry operators are obtained. Also, the optimal system of one-dimensional subalgebras of the equation is constructed. The Lie invariants as well as similarity reduced equations corresponding to infinitesimal symmetries are obtained. The nonclassicaJ symmetries of the （2D） DKS equation are also investigated.

A novel carbon ceramic electrode consisting of Cu NPs and MWCNT was developed to treat reactive orange 84(RO84) wastewater using ultrasound-assisted electrochemical degradation. The proposed electrode generated more hydroxyl radicals than non-nanoparticle electrodes did. In addition, a new electrochemical sensor was applied to determine residue RO84 in an aqueous medium during discoloration. This sensor is based on a glassy carbon electrode modified with gold nanourchins and graphene oxide and can detect RO84 concentration in the range of 1.0–1200 μmol·L^-1 with the detection limit of 0.03 μmol·L^-1. The degradation effects of the modified electrode on RO84 were evaluated systematically with different initial pH values, time durations, and amounts of Cu NPs and MWCNT. The results suggested that the removal efficiency of RO84 was approximately 83% after120 min of electrolysis in a phosphate buffer with pH 8.0 using a carbon ceramic electrode made with 4.0 wt%Cu NPs and 4.0 wt% MWCNT. The possible mechanism of RO84 degradation was monitored by gas chromatography–mass spectrometry, and degradation pathways were proposed.

Abstract We consider the BSBM （Bekenstein, Sandvik, Barrow and Magueijo） cos- mological model in the presence of tachyon potential with the aim of studying the sta- bility of the model and test it against observations. The phase space analysis shows that from fourteen critical points that represent the state of the universe, only one is stable. With a small perturbation, the universe transits from a state of unstable deceleration to stable acceleration. The stability analysis combined with the best fitting process imposes constraints on the cosmological parameters that are in agreement with ob- servation. In the BSBM theory, the variation of fundamental constants is driven from variation of a scalar field. The tachyonic scalar field, responsible for both variation of fundamental constants and universal acceleration, is reconstructed.

OBJECTIVE: To evaluate anticancer efficacy of green tea extract(GTE) on PC3 prostate cancer cells. METHODS: By using quantitative real-time polymerase chain reaction(qRT-PCR) and Western blot methods, the expression of miR-195 and the epithelial to mesenchymal transition(EMT) markers such as E-cadherin and vimentin was analyzed. RESULTS: Based on the results of 2D and 3D cell culture models, the inhibition of EMT and up regulation of miR-195 expression were detected. CONCLUSIONS: Our findings will be helpful to design anti-tumor regimens with natural product original, and more studies will be required to identify the related mechanisms involving anticancer activities of green tea via miRNAs.

Shahre-Babak ophiolite is a part of the inner Zagros ophiolite belt in Iran. Major parts of intrusive masses of Share-Babak ophiolite are gabbro and plagiogranite. The SiO2 versus Na2O＋K2O diagram shows that the palgiogranites are related to calk-alkaline series. Rare earth elements exhibit relatively similar pattern that indicates these rocks are syngenetic. Also, REE patterns display an enrichment of LREE compared to HREE, and are characterized by flat to slightly concaveup patterns from Gd to Yb. Such patterns contrast sharply with those of plagiogranites in more complete ophiolite sequences, such as the Semail ophiolite, Oman, or the Troodos ophiolite, Cyprus, and Neyriz, where patterns are much flatter and slightly LREE-depleted. The slightly LREE-enriched patterns of the Shahre-Babak plagiogranites support a partial melting origin for them. The low TiO2, Nb, Ta content and high LREE concentrations of the Shahre-Babak plagiogranites indicate that the rocks were likely derived from the anatexis of amphibolites, which were related to hydrothermal alteration of gabbros in intra-oceanic back-arc basin.

Full polysaccharide crosslinked-chitosan membranes were prepared by crosslinking of chitosan with chitosan dialdehyde followed by reduction with sodium borohydride. Partially oxidized chitosan, generated from periodate oxidation of chitosan, was used as a crosslinker. The modulus values and elongation at break were increased with increasing the crosslinker weight ratio. The rheological measurements showed that depolymerization of chitosan can take place rapidly in the presence of the oxidizing agent. The weight reduction of crosslinked-chitosan membrane after 12 h, at pH = 4 and pH = 2 was found to be 85.0% and 90.0%, respectively. The structure of the crosslinked-chitosan and the silver nanocomposite were confirmed by FTIR spectroscopy, scanning electron microscopy （SEM）, and thermogravimetric analysis （TGA）. Transmission electron microscopy （TEM） reveals the presence of well-separated Ag nanoparticles with diameters in the range of 4-10 nm. The silver ion loading increases with increasing the silver ion concentration, and decreasing the crosslink density. The MBC/MIC ratio of 2.0, 2.0, and 1.0 was achieved for E. coli, S. aureus, and P. aeruginosa, respectively.
