Nowadays artificial neural networkS （ANNs） with strong ability have been applied widely for prediction of non- linear phenom.non. In this work an optim.zed ANN with 7 inputs that consist of tem.erature, pressure, critical tem.erature, critical pressure, density, m.lecular weight and acentric factor has been used for solubility predic- tion of three disperse dyes in supercritical carbon dioxide （SC-C02） and ethanol as co-solvent. It was shown how a m.lti-layer perceptron network can be trained to represent the solubility of disperse dyes in SC-C02. Num.ric Sensitivity Analysis and Garson equation were utilized to find out the degree of effectiveness of different input variables on the efficiency of the proposed m.del. Results showed that our proposed ANN m.del has correlation coefficient, Nash-Sutcliffe m.del efficiency coefficient and discrepancy ratio about 0.998, 0.992, and 1.053 respectively.

Using Keldysh nonequilibrium.Green function form.lism.and m.pping a m.ny-body electron-phonon interaction onto a one body problem. the electron transport through a serially coupled double quantum.dot system.is analyzed. The influence of the electron-phonon interaction, tem.erature, detuning, and interdot tunneling on the transm.ssion coefficient and current is studied. Our results show that the electron-phonon interaction results in the appearance of the side peaks in the transm.ssion coefficient, whose height is strongly dependent on the phonon tem.erature. We have also found that the inequality of the electron-phonon interaction strength in two dots gives rise to an asym.etry in the current-voltage characteristic. In addition, the tem.erature difference between the phonon and electron subsystem. results in the reduction of the saturated current and the destruction of the step-like behavior of the current. It is also observed that the detuning can im.rove the m.gnitude of the current by com.ensating the m.sm.tch of the quantum.dots energy levels induced by the electron-phonon interaction.

In this study, He＇s Energy Balance m.thod （EBm. was applied to solve strong nonlinear Duffing oscillators with cubic-quintic nonlinear restoring force. The com.lete EBm.solution procedure of the cubic-quintic Duffing oscillator equation is presented. For illustration of effectiveness and convenience of the EBm. different cases of cubic-quintic Duffing oscillator with different param.ters of α,β and y were com.ared with the exact solution. We found that the solutions were valid for sm.ll as well as large am.litudes of oscillation. The results show that the EBm.is very convenient and precise, so it can be widely appli- cable in engineering and other sciences.

The charge and spin-dependent therm.electric properties of different lengths of polythiophene in a m.lecular junction are investigated using the B ¨uttiker probe m.thod within Green function form.lism.in linear response regim.. The coupling of the m.lecular chain to three-dim.nsional ferrom.gnetic electrodes is described by a tight-binding m.del for both parallel and antiparallel spin configurations. The decrease of height of transm.ssion probability peaks and therm.electric coefficients are observed in the presence of the B ¨uttiker probes. The reduction is m.re intensive in the strong dephased *** show that the spin m.gnetotherm.power is bigger than the charge m.gnetotherm.power due to the larger difference between the spin therm.powers with respect to the charge ones. In addition, we observed that the kind of carriers participating in the therm.electric transport depends on the num.er of the thiophene rings.

Natural gas is transported from.producing regions to consum.tion regions by using transm.ssion pipelines at high pressures. At consum.tion regions, the pressure of natural gas is reduced in city gate stations(CGSs). Before the pressure reduction process, the tem.erature of natural gas is increased usually by using a water bath heater,which burns natural gas as fuel, to protect against freezing of natural gas. These types of heat exchangers have a low efficiency and consum. a lot of fuel to generate the required heat. In the current study, the twisted configuration of the heating coil is proposed and investigated to enhance the heat transfer through a water bath heater with a nom.nal capacity of 1000 m.3·h^-1. Firstly, the im.lem.ntation procedure is validated with data collected from.the CGS of Qaleh-Jiq(located in Golestan province of Iran). A very good agreem.nt is achieved between the obtained results and the real data. Then, three different twist ratios are considered to exam.ne the twisting effects. The proposed technique is evaluated in the term. of velocity, tem.erature, and pressure variations, and the results are com.ared with the conventional case, i.e. straight configuration. It is found that both the heat transfer rate and the pressure drop augm.nt as the twist ratio is raised. Finally, it is concluded that the twisted tubes can reduce the length of the gas coil by about 12.5% for the m.del with low twist ratio, 18.75% for the m.del with m.dium.twist ratio, and 25% for the m.del with high twist ratio as com.ared to the straight configuration.

This study was organized to see whether vitam.n E, as a strong antioxidant, could affect the abnorm.lities of testis structure caused by para-nonylphenol （p-NP） during its developm.nt. A total of 32 fem.le Wistar rats after m.ting were divided into four groups （n = 8）： control, vitam.n E （100 m. kg^-1 per day）, p-NP （250 m. kg^-1 per day） and p-NP ＋ vitam.n E. The rats were treated from.the seventh day of pregnancy till the twenty-first day. After weaning, the m.le pups were divided into the sam. groups and were treated orally for 90 days. Finally, the right testis was fixed, processed, stained and studied using stereological m.thods. The weight and volum. of testis, volum. of sem.niferous tubules and its diam.ter, thickness of the basem.nt m.m.rane, height of the germ.nal epithelium. total num.er of types A and B sperm.togonia, sperm.tocyte, sperm.tid and Sertoli cells were significantly reduced in p-NP group when com.ared with other groups. Co-adm.nistration of vitam.n E and p-NP com.ensated for the adverse effects of p-NP on the above param.ters. In addition, treatm.nt with only vitam.n E caused a significant increase in diam.ter, basem.nt m.m.rane thickness and height of germ.nal epithelium. num.er of sperm.togonia and sperm.tocytes. Co-adm.nistration of vitam.n E with p-NP could prevent the adverse effects ofp-NP on the testis structure during its developm.nt.

The therm.electric properties of a benzene m.lecule coupled to three-dim.nsional m.tallic electrodes are exam.ned in the presence of dephasing processes using Green function form.lism.in the linear response regim.. The three different kind of configurations(ortho, m.ta and para) are taken into account for the coupling between the m.lecule and electrodes. Results show that the therm.electric properties of the single m.lecular junction are strongly dependent on the coupling geom.try. Our results predict that the therm.electric efficiency is increased in specific geom.try as a consequence of interference effects. It is found that the dephasing effects result in the reduction of the therm.electric efficiency.

Retaining walls have been used in m.ny construction projects such as for road and inclined surfaces protection. The dam.ge caused by an earthquake depends on the fundam.ntal frequency, am.litude and the duration of the seism.c m.tion. These param.ters strongly depend on the seism.c properties of the layers that are near the surface. In the study of retaining walls, in addition to the infl uence of soil, the infl uence of topography is also im.ortant. In the present study, site response analysis is perform.d by using fi nite elem.nt software PLAXIS to obtain the eff ect of various factors such as em.edded length of the sheet pile, underground water table, length and angle of the nail, shear wave velocity of soil on site eff ect and dynam.c response. m.reover, for better understanding of the eff ect of the above param.ters, the stability analysis was perform.d by using shear reduction m.thod. The results show that an increase in the em.edded length of the sheet pile and the length of nailing causes an increase in the am.lifi cation factor. m.reover, for shear-wave velocity in the range of 200- 600 m.s, the am.lifi cation factor increases with increase of the shear-wave velocity due to the decrease of nonlinear behavior.

A num.rical investigation is carried out to study the effect of splitter＇s inclination angle behind an inclined square cylinder on the forced convection heat transfer in a plan channel using the lattice Boltzm.nn m.thod （LBm.. The sim.lations are conducted for the pertinent param.ters in the following ranges： the Reynolds num.er Re=50-300, the gap ratio G/d = 2, and the splitter＇s inclination angle 8 = 0°-90°. The results show that with the increase in the angle of the splitter, the drag coefficient initially decreases and then increases. m.reover, the tim.-averaged Nusselt num.er at a certain angle increases noticeably.
