Scalar-field dark energy models like tachyon are often regarded as an effective description of an underlying theory of dark energy. In this Letter, we implement the interacting agegraphic dark energy models with tachyon field. We demonstrate that the interacting agegraphic evolution of the universe can be described completely by a single tachyon scalar field. We thus reconstruct the potential as well as the dynamics of the tachyon field according to the evolutionary behavior of interacting agegraphic dark energy. © 2009 Elsevier B.V. All rights reserved.

Complicated schemes of classical breeding and their drawbacks, environmental risks imposed by agrochemicals, decrease of arable land, and coincident escalating damages of pests and pathogens have accentuated the necessity for highly efficient measures to improve crop protection. During co-evolution of host-microbe interactions, antimicrobial peptides (AMPs) have exhibited a brilliant history in protecting host organisms against devastation by invading pathogens. Since 1980s, a plethora of AMPs has been isolated from and characterized in different organisms. Nevertheless the AMPs expressed in plants render them more resistant to diverse pathogens, a more orchestrated approach based on knowledge of their mechanisms of action and cellular targets, structural toxic principle, and possible impact on immune system of corresponding transgenic plants will considerably improve crop protection strategies against harmful plant diseases. This review outlines the current knowledge on different modes of action of AMPs and then argues the waves of AMPs' ectopic expression on transgenic plants' immune system. © 2011 Landes Bioscience.

The objective of this paper was to present a comprehensive analysis including analytical and numerical models which were developed to predict the performance of a solar chimney power plant in Kerman, Iran. The numerical model results including air temperature, velocity and electrical power output were validated by comparing with experimental data of the Manzanares prototype power plant. Also the mathematical model was verified with the practical power output of the Kerman pilot plant. Also in this paper, a novel approach to evaluate the influence of the site altitude on the potential of solar chimney power plants was presented and thereby a coefficient called altitude effectiveness was defined using Manzanares prototype geometrical parameters in different site altitudes. The developed model was applied to improve the performance of a solar chimney pilot power plant built in Kerman, Iran. Based on an approximate cost model, the thermo-economic optimal configurations of the pilot power plant were illustrated; and also it was found that the chimney diameter was the most important structural dimension to improve the performance of this pilot power plant. © 2012 Elsevier Ltd.

In this research work, α-Fe2O3 nano-particles were prepared by direct thermal-decomposition of γ-Fe2O 3. Precursor powders (γ-Fe2O3) were synthesized by wet chemical method at room temperature and then, the precursors were subsequently calcined in air for 1 h at 500°C. Samples were characterized by thermal gravimetric analysis (TGA), X-ray diffraction (XRD), energy dispersive spectra (EDS), infrared spectrum (IR) and transmission electron microscopy (TEM), respectively. The XRD, EDS, and IR results indicated that the synthesized α-Fe2O3 particles were pure. The TEM image showed that the α-Fe2O3 nano-particles were spherical and 18 ± 2 nm in size. Magnetic properties have been detected by a vibrating sample magnetometer (VSM) at room temperature. The γ-Fe2O3 and α-Fe2O3 nano-particles exhibited a super-paramagnetic and weak ferromagnetic behavior at room temperature, respectively. Using the present method, hematite nano-particles can be produced without expensive organic solvent and complicated equipment. © 2010 Elsevier B.V.

Nanofluids, a new thermal fluids, have scientific challenges because the existing theories underpredict their thermal conductivity. One way to calculate this parameter is equilibrium molecular dynamics (EMD). In the previous studies of EMD, the thermal conductivity of nanofluids was calculated by the autocorrelation function of the heat current through the Green-Kubo formula. The convergence of this function requires a large time, nevertheless convergence of integral may still be slow or not well behaved. In this study, a new method based on combination of equilibrium and non-equilibrium molecular dynamics simulation in a non-periodic boundary conditions was used to calculate the thermal conductivity. In this method, first the specific heat and the thermal diffusivity of a nanofluid were determined by EMD and non-equilibrium (NEMD) respectively. Then the thermal conductivity was calculated from the relation of thermal diffusivity with the constant volume specific heat. This approach was tested by the nanofluid of silicon nitride nanoparticles in a liquid argon. The CHARMM22 force field and the force field of silicon nitride were combined to perform the simulation. The nanoparticle was generated according to the data of X-ray crystallography. The results of simulation for the base fluid at different temperatures were compared with experimental data to check the accuracy of the MD modeling. The effects of temperature and nanoparticle loadings on the thermal conductivity were investigated. The results showed that the thermal conductivity increases with increasing the loadings and decreasing the temperature. The calculation of root mean square displacements for liquid argon showed that the thermal transport enhancement of the nanofluid was mostly due to the increased movement of liquid phase atoms in the presence of non-metallic nanoparticle. This finding was also confirmed by the analysis of the density profile of liquid atoms near the interface. Finally, the comparison of the results of this study with other researchers showed the kind of nanoparticle could not significant to increase the thermal conductivity of nanofluids. © 2012 Elsevier B.V.

Biosurfactants are surface active materials that are produced by some microorganisms. These molecules increase biodegradation of insoluble pollutants. In this study sediments and seawater samples were collected from the coastline of Bushehr provenance in the Persian Gulf and their biosurfactant producing bacteria were isolated. Biosurfactant producing bacteria were isolated by using an enrichment method in Bushnell-Hass medium with diesel oil as the sole carbon source. Five screening tests were used for selection of Biosurfactant producing bacteria: hemolysis in blood agar, oil spreading, drop collapse, emulsification activity and Bacterial Adhesion to Hydrocarbon test (BATH). These bacteria were identified using biochemical and molecular methods. Eighty different colonies were isolated from the collected samples. The most biosurfactant producing isolates related to petrochemical plants of Khark Island. Fourteen biosurfactant producing bacteria were selected between these isolates and 7 isolates were screened as these were predominant producers that belong to Shewanella alga, Shewanella upenei, Vibrio furnissii, Gallaecimonas pentaromativorans, Brevibacterium epidermidis, Psychrobacter namhaensis and Pseudomonas fluorescens. The largest clear zone diameters in oil spreading were observed for G. pentaromativorans strain O15. Also, this strain has the best emulsification activity and reduction of surface tension, suggesting it is the best of thee isolated strains. The results of this study confirmed that there is high diversity of biosurfactant producing bacteria in marine ecosystem of Iran and by application of these bacteria in petrochemical waste water environmental problems can be assisted. © 2014 Elsevier Ltd.

In this research work, mathematical models are presented for single and two-glass cover solar air collector systems with natural convection flow. These models are based on an analytical solution of energy balance equations for various elements of collectors. The results obtained from the present work and the experimental results of other researchers are in good agreement. The effects of a tin metal sheet suspended in the middle of the air channel, longitudinal fins with rectangular and triangular shapes, and depth and length variations of the channel on energy and exergy efficiencies of solar air collectors are also investigated. The results show that the collector with two-glass covers has a better performance than a single-glass collector, and it is analytically preferred by the first and second laws of thermodynamics. The results also illustrate that the collectors with triangular fins are more efficient in terms of energy than those with rectangular fins. © 2014 Elsevier Ltd.

This paper describes the development, electrochemical characterization and utilization of a novel modified molybdenum (VI) complex-carbon nanotube paste electrode for the electrocatalytic determination of isoproterenol (IP). The electrochemical profile of the proposed modified electrode was analyzed by cyclic voltammetry (CV) that showed a shift of the oxidation peak potential of IP at 175 mV to less positive value, compared with an unmodified carbon paste electrode. Differential pulse voltammetry (DPV) in 0.1 M phosphate buffer solution (PBS) at pH 7.0 was performed to determine IP in the range from 0.7 to 600.0 μM, with a detection limit of 35.0 nM. Then the modified electrode was used to determine IP in an excess of uric acid (UA) and folic acid (FA) by DPV. Finally, this method was used for the determination of IP in some real samples. © 2011 Elsevier Ltd. All Rights Reserved.

The main problem in using photovoltaic (PV) systems is the low energy conversion efficiency of PV cells. The efficiency of PV cells will decrease significantly as the temperature of the cells exceed to a certain limit. In order to increase the efficiency, it is necessary to reduce the operating temperature of array. One of the ways for improving the system operation is cooling PV cells with a thin film of water. The aim of this research is to study the effects of nominal power of array and system head on the operation of system by using this method. For this purpose, a photovoltaic water pumping system is installed in Kerman city (Latitude: 30 ° 17′ and longitude: 57 ° 50′) and different methods examined to reduce PV cells temperature. The most effective way was chosen and used in set. This method is based on providing water for cooling cells by the pump itself. Experiments show that with decreasing of array nominal power and increasing in system head, the power generated by the array increases significantly. This increases the panel and total efficiency and therefore the pump flow rate. This method is ineffective as the array nominal power increases significantly. © 2009 Elsevier Ltd.
