Hormuz and Gachin salt domes are located on the Zagros Belt, about 17 km south and 50 km west of Bandar Abbas, respectively. Extensive outcrops of rhyolite and tuffs are observed in these salt domes. The main constituent minerals of rhyolite include hematite, magnetite, pyrite, chalcopyrite and apatite (Hormuz salt dome). Geochemical evidence indicates that the rhyolite of the Hormuz and Gachin domes belongs to the calc-alkaline to shoshonitic of magmatic series and formed during a tectonic regime of active continental margin volcanic arcs. Absence of negative Nb anomaly and positive anomaly of Pb in Hormuz and Gachin rhyolites indicate magma derived from the mantle source with low contamination from crustal rocks and subduction-dependent. The average ​​of (La/Yb)N and (Ce/Yb)N ratios as index (LREE/HREE) indicate high enrichment of LREE against HREE for Hormuz rhyolite versus Gachin rhyolite,. Strong and positive correlation between ΣREE with Fe, P and Ca oxides as well as positive La and Ce anomalies and negative P anomaly in Hormuz rhyolite samples compared to Gachin samples, are consequence of the presence of apatite mineral in these rocks. The distribution pattern of Light Rare Earth Elements in Hormuz salt dome apatites show a more regular and uniform trend. Thus (LREE) show more adaptation to focus on apatite minerals. The low ratios of Eu/Eu* in apatites of Hormuz (0.01-1.04 ppm) rather than ryholites of Gachin (0.1-3.1 ppm) shows changes in the magma composition during the formation of apatites. In addition, increases in negative Eu anomaly can be due to the crystallization of feldspars that separate Eu from the melt and its concentration; therefore, the Hormuz apatites indicates a high degree of differentiation. In Hormuz salt dome apatites, enrichment of LREE to HREE, negative Eu and positive Ce anomalies and significant ΣREE concentrations up to 8882 ppm as the indicator mineral plays an important role in evaluating the distribution of rare earth elements in the rhyolite of the Hormuz salt dome.

During this research, the formulation of manganese phosphate bath was designed to create layers on the surface of low carbon steel alloys (St 37) to enhance corrosion, abrasion and friction resistance. At the first, a basic solution of the manganese phosphate bath was prepared by optimizing the concentration of each components of the bath. Then, the effects of potassium oxalate and nickel oxide additives on coating properties such as thickness, unit weight of surface (With optimal value of 1± 0.1 gr/l nickel oxide, the weight of the coating 39.8 ± 0.2 gr/m was obtained and optimal value of 0.5±0.1 gr/l potassium oxalate, the weight of the coating 48.99±0.3 gr/m2 was obtained), morphology, corrosion and abrasion resistance were investigated and finally, the best coating determined.The results of various experiments showed that the major phase of manganese phosphate coating is Hureaulite, which is in the form of cubic crystals in the basic solution that does not contain any additives, of course, with the addition of additives, the shape of the crystals is changed and the particle size becomes smaller and denser. The highest corrosion resistance obtained during the salt spray test (98 hours) and electrochemical impedance spectroscopy (EIS) (with Polarization 77983±253) is related to phosphate coating containing nickel oxide. According to the results of the Pin on disk test the specimens which were phosphated and soaped reduced the coefficient of surface friction from about 0.6 (for uncoated steel) to about 0.15, and this indicated the anti-abrasion and friction properties of these coatings.

The issue of meeting children is important and in addition to parents, states also play a role. In fact, children, due to their low age, need special protection to enforce their rights. Therefore, in situations where the course of life of children is affected by events such as parental divorce, displace-ment or immigration, it is very important for them to communicate with their pare-nts and relatives. Since 1959 and since the adoption of the Declaration on the Rights of the Child, there have been several international and regional human rights instruments to support the rights of the child. However, children are faced with the challenge of visitation in many cases due to parents' selfishness and failing to to carry out their duties or due to the negligence of states in protecting the rights of children. Although visitation of children is not considered as a duty, it is considered as a right for parents and children and affects various children's rights such as health and identity rights.

Divinylbenzene (DVB) is produced by catalytic dehydrogenation of DEB at high temperature and atmospheric pressure. Ethylvinylbenzene (EVB) is produced as a useful chemical during dehydrogenation of DEB. Also some other liquid and gaseous by products is produced during dehydrogenation. A set-up has been developed to conduct the DEB dehydrogenation reactions experiments to prepare DVB at different conditions. Model equations for DEB dehydrogenation reactor have been solved by genetic algorithm (GA) method using MATLAB software. Reaction rate constants and absorption coefficients were determined at various temperatures. The conversion of DEB and ethylvinyl benzene (EVB) in the reactor was predicted by mathematical modeling and compared with experimental results. The comparison shows good agreements between experimental and modeling results. The combined effects of DEB flow rate and catalyst weight as time factor were investigated on conversion of DEB and production of EVB and DVB. Effects of temperature on consumption of DEB and production of EVB and DVB in the tubular reactor were investigated.

IPM is a combination of crop protection practices to keep pests below economic threshold, and one of them is to make the host plants resistant. Various parameters such as the application of fertilizers, irrigation and providing optimum conditions for host plant can benefit its resistance to pests. In order to induce resistance on cucumber (Kish var.), the foliar spray of phosphorus and potassium were incorporated for observing the Tetranychus urticae performance. Therefore, four Fosfalim-k concentrations (i.e. 0, 1, 10 and 30 ml L-1) were sprayed on cucumber (Kish var.) in three time intervals and the life table parameters of T. urticae were studied in the laboratory conditions. The measured plant characteristics included fresh and dry mass, total protein, chlorophyll, carotenoid and the activity of antioxidant enzymes (CAT, APX and GPX). The age-stage, two-sex life table parameters of T. urticae were analyzed using TWOSEX-MSChart software. The 30 ml L-1 concentration caused plant defoliation and was deleted from results. The results showed that CAT and APX enzymes activity and carotenoid concentration were significantly increased while fresh and dry mass and chlorophyll concentration were decreased in response to 10 ml L-1Fosfalim-k. In the studied life table parameters of T. urticae, λ, R0 and r parameters were decreased significantly in this concentration. Hence, spraying cucumber with Fosfalim-k can decrease survival and fecundity of T. urticae and the suggested concentration could be 10 ml L-1.

In this study, the effect of spraying of Zinc oxide nanoparticles at three concentrations (0, 1000 and 2000 ppm) on the response of Capsicum annuum L. to different levels of salinity (0, 25, 50 and 75 mM NaCl) was evaluated. The experiment was carried out as factorial based on randomized complete block design with four replications in pot culture conditions. The high concentration of salt and Zinc oxide nanoparticles reduced the amount of chlorophyll, carotenoids, total phenol, leaf dry weight, proline content, total soluble carbohydrate, plant height, stem diameter and catalase enzyme activity but increased the amount of malondealdehyde (MDA). Rising the salinity level to 50 mM, increased the soluble carbohydrates content but further increase to 75 mM salinity led to decrease in the soluble carbohydrates content. The interaction of salinity and Zinc oxide nanoparticles was significant on chlorophyll, proline, malondealdehyde (MDA), total phenol, carotenoids, and soluble carbohydrates concentrations, and leaf dry weight. The result of this experiment showed that Zinc oxide foliar application in the form of nanoparticles is potent to reduce the damages of salinity to pepper.

In this paper, the pH control solution is considered in a laboratory reactor. A prototype of an acid and an open stream is continuously coupled to the reactor tank in an appropriate proportions is used for PH process control then, according to the PEM table, the equation of the pH state is obtained after that with Optimizing the PI coefficients, the PI controller is designed. The classic PI controller was not able to control this process, so the state-of-the-art observer was used, which was able to control with high precision. The proposed observer estimates state variables with extreme precision due to linear design. In the design of non-linear observation, sliding mode control is used. This method is suitable for estimating the state variables of the non-linear nonlinear systems, but due to the occurrence of chattering, its efficiency is greatly reduced. In order to prevent chattering and also to increase the accuracy, the second-order slip-off theory of the flicker is used to design non-linear observation. Finally, a nonlinear viewer is designed and simulated by using of modeling theory.

Heat transfer occurs in flow boiling; as a result, the amount of heat between the tube wall surface and the fluid at different points of the tube may vary depending on the volume percent of vapor at those points. If the flow is fully vaporized, it does not allow for perfect heat transfer at that point; this significantly increases the temperature there; in this case the applied heat flux is called critical heat flux (CHF). The present paper has focused its attentions on simulating a two-phase fluid flow within the CHF range using ANSYS Fluent. The simulation results indicated an average error below 7%, which is more than those obtained by the experimental results. The maximum temperature of the tube surface when applying CHF could range between 200 and 500 K degrees more than that of fluid saturation according to the fluid working conditions. It also should be noted that both CHF and maximum temperature increase as the input pressure and mass flux do increase.

Also in this research we found the importance of auxiliary equipment. Auxiliary equipment helps that significant amount of hydrogen production to be saved. This amount at 577 K is equal that produces 0.093 kg H2/s

Friction stir welding (FSW) process is a method for joining the aluminum alloys. Nowadays, it is considered to form the blanks fabricated by this method. Single point incremental forming (SPIF) is used to manufacture complex shapes with high depth which is not possible with traditional methods. SPIF is a flexible method for low production or manufacturing a prototype model. In this paper, experiments are performed on the blanks fabricated by FSW process to study the effect of the SPIF parameters. The first step conducted to investigate the influence of rotational speed and feed rate of friction stir welding process on mechanical properties of AA 6061-T6. The output of this step is the appropriate samples for next step. In the next step, the effect of the lubrication, rotational speed, feed rate and tool trajectory has been studied on thickness reduction (thinning), surface roughness and formability. The results show the lubricant and tool trajectory increase the depth of formation up to 1.6 times. Also, these two parameters improve the effects of thickness reduction and surface quality.

DEB dehydrogenation reaction was conducted to produce divinylbenzene (DVB) and ethylvinylbenzene (EVB). The effects of temperature, catalyst weight and time factor on the performance of the dehydrogenation reactor were investigated experimentally. Temperature was varied from 550º C up to 600 º C. Temperature affect the conversion of DEB to DVB significantly. The mole fraction of DEB in the outlet of the reactor is reducing up to 580 º C, but further increase in temperature up to 600 º C does not decrease the mole fraction of DEB in the outlet of the reactor. Catalyst weight was varied from 10 gr up to 40 gr. The results showed that the trends of EVB+DVB production and DEB consumption are identical at various catalyst weights. To obtain optimum time factor for the DEB dehydrogenation process experiments were conducted at various time factors. The results showed that the optimum time factor for DVB as a desired product is 825 gr/hr.mole. . The data and information provided in this research can be used for scale-up and optimization purposes.

Electronic tiltmeter is used as a tool of setting the accurate angles in advanced equipment. The accuracy and precision of tiltmeter should be evaluated by means of precise calibration equipment. This study aimed to calibrate and evaluate the accuracy of a precise dual axis electronic tiltmeter. To this end, a calibration setup with accurate positioning capability was designed and constructed. Then the calibration setup was employed to investigate linear and nonlinear behavior of electronic tiltmeter and extract the corresponding equations. In order to assess the reliability of the tiltmeter sensor, nonlinearity error and repeatability of the tiltmeter at different angles were obtained. Afterwards in an analytic way, arithmetic and geometric means were compared and the factors which affect the calibrator output error were identified to obtain that how much the accuracy and measurement error of each of those factors affect the uncertainty of angle measurement in the calibration process. The results indicate that both introduced methods of averaging can be used to derive relationship of uncertainty propagation accurately. Uncertainty analysis of the constructed base and calibration process demonstrate that the employed equipment correspond with the evaluation of a precise electronic tiltmeter.

The Siahrudbar bauxitic horizon is located in ~25 km southwest of Aliabad Katoul, Golestan Province, north of Iran. This deposit is stratiform and were developed along the boundary of the Elika and Shemshak formations. Petrographic observations along with the results of XRD analyses of the ore samples revealed that diaspore, hematite, and kaolinite are the major constituent minerals which are accompanied by lesser amounts of chamosite, anatase, boehmite, goethite, rutile, calcite, muscovite, clinochlore, and quartz. These minerals display various textures including pelitomorphic, granular, pseudo-porphyry, fluidal, pseudo-breccia, dumbbell-shaped grains, and clastic fragments, indicating allogenic origin. Based upon quantitative values of minerals, the Siahrudbar deposit consists of two types of ores, (1) the clayey bauxite and (2) the bauxitic clay. These ores were formed during deferrugenization and desilication processes from the clay minerals. The geochemical data of less mobile elements indicate that the Siahrudbar deposit is of karst bauxite type and generated from the weathering of igneous (basaltic-andesitic) rocks. Furthermore, the Eu anomaly values together with the ratios of TiO2/Al2O3 and Sm/Nd revealed that the Siahrudbar bauxitic deposit was formed in a continental margin tectonic setting.

The porosity within a reservoir rock is a basic parameter for the reservoir characterization. The present paper introduces two intelligent models for identification of the porosity types using image analysis. For this aim, firstly, thirteen geometrical parameters of pores of each image were extracted using the image analysis techniques. The extracted features and their corresponding pore types of 682 pores were used for training two intelligent models, BPN (back-propagation network) and SAE (stacked autoencoder). The trained models take the geometrical properties of pores to classify the type of six porosity types including
intra-particle, inter-particle, vuggy, moldic, biomoldic, and fracture. The MSE values for the BPN and SAE models were found to be 0.0042 and 0.0038, respectively. The precision, recall, and accuracy of the intelligent models for classifying the types of pores were calculated. The BPN model was able to correctly recognize 193 intra-particle pores out of 197 ones, 45 inter-particle pores out of 50 ones, 7 vuggy pores out of 9 ones, 10 moldic pores out of 12 ones, 2 biomoldic pores out of 3 ones, and 6 fractures out of 7 ones. Also the SAE model was able to correctly classify 193 intra-particle pores out of 197 ones, 46 inter-particle pores out of 50 ones, 8 vuggy pores out of 9 ones, 10 moldic pores out of 12 ones, 3 biomoldic pores out of 3 ones, and 7 fractures out of 7 ones. The results obtained showed that the SAE model carried out a bit more accuracy for classification of the inter-particle, vuggy, biomoldic, and fracture pores.

Transversal oscillation of coronal loops that are interpreted as signatures of magneto hydrodynamics (MHD) waves are observed frequently in active region corona loops. The amplitude of this oscillation has been found to be strongly attenuated. The damping of transverse oscillation may be produced by the dissipation mechanism and the wake of the traveling disturbance. The damping of transversal loop oscillations with wake phenomena is not related to any dissipation mechanism. Also, these kinds of coronal loop oscillations are not related to the kink mode, although this mode can be occurred after the attenuation process by the energy of the wave packet deposited in the loop. In this paper the excitation and damping of transversal coronal loop oscillations with wake of traveling wave packet is discussed in detail, both theoretically and observationally. Here, the transversal coronal loop oscillations is modeled with a one dimensional simple line-tied. The dynamics of the loop and the coronal is governed by the Klein–Gordon differential equation. A localized disturbance that can be generated by nearby flare produces a perturbation that undergoes dispersion as it propagates toward the loop. As a consequence, the amplitudes of oscillates decay with time roughly t-1/2 at the external cutoff frequency. These observed data on 2016-Dec-4 by Atmospheric Imaging Assembly (AIA) onboard Solar Dynamic Observatory (SDO) observations data, consisting of 560 images with an interval of 24 seconds in the 171 A0 pass band is analyzed for evidence of excitation and damping of transverse oscillations of coronal loop that is situated near a flare. In this analyzed signatures of transverse oscillations that are damped rapidly were found, with periods in the range of P=18.5-23.85 minutes. Furthermore, oscillation of loop segments attenuate with time roughly as t-α that average values of α for 4 different loops change form 0.65-0.80. The magnitude values of α are in good agreement with theoretical prediction for damping of transverse loop oscillations by wake of the traveling wave packet that can be considered responsible for the rapid damping of the observed oscillations.

Mesgarabad area is located in ~10 km southeast of Tehran, the Central- Alborz structural zone (CASZ) of Iran. The rock units exposed in the area consist of Eocene volcanics, volcano-sedimentary and sedimentary rocks intruded by post upper Eocene granodiorite to quartz monzo-diorite. These subvolcanic intrusive bodies show porphyroid to microgranular textures and have calc-alkaline magmatic nature. These bodies produced hydrothermal fluids causing extensive alteration zones developed along the Se-Darreh-e-Bozorg strike-slip fault. The effects of hydrothermal fluids on the entire Eocene rock units and subvolcanic intrusive bodies are remarkable. The main alterations are silicification, sericitization, chloritization, epidotizaton, actinolitization, argillization, carbonatization, and alunitization-jarositization, which provided suitable physico-chemical conditions for ore-mineralization. The penetration of subvolcanic intrusive bodies into the Eocene volcanics, volcano-sedimentary and sedimentary rocks brought about skarn mineralization and epithermal barite veins. Microscopic studies and advanced analysis showed that the principal mineral phases in the epithermal zones are magnetite, pyrite, chalcopyrite, bornite, chalcocite, barite, Cu䩿 alloy, hematite, psilomelane, jacobsite, martite, geothite, and lepidochrosite. The skarnification processes occurred at two distinct stages, (1) progressive and (2) retrogressive. The pyrometasomatic anhydrous minerals such as andradite-grossularite formed during progressive stage and the hydrous minerals like epidote, chlorite, tremolite- actinolite, calcite, quartz, pyrite, chalcopyrite and chalcocite were developed during retrogressive stage. Fluid inclusion studies on primary aqueous inclusions trapped in barite crystals revealed fluid that mixing of two fluids having different physico-chemical conditions played an important role for ore deposition.

Anzali wetland is one of the most important wetlands in the southern coast of the Caspian Sea which is under the influence of the brackish water of the Caspian Sea and the freshwater rivers entering it. Therefore, it plays important role as an exclusive ecotone. Physicochemical conditions and trophic levels of the Anzali Wetland were evaluated monthly from May 2014 to May 2015. Trophic State Index (TSI) was calculated based on the evaluation of chlorophyll a, total phosphorus (TP), total nitrogen (TN) and water transparency. The results showed that the average annual amounts of total nitrogen, total phosphorus and dissolved oxygen were 1.023±0.523, 0.113±0.105 and 8.71±2.63 mgL-1, respectively. The amounts of total nitrogen were not significantly different among various research locations (P>0.05), whereas the amounts of total phosphorus were significantly different among various research locations (P

Grape leafhopper, Arboridia kermanshah Dlabola(Hemiptera: Cicadellidae), is the most important pest of vineyards in Iran, that by laying eggs in the leaf tissue, feeding on leaves and transmission of viral pathogens, weaken the trees and reduce the quality and quantity of grape production. To reduce the use of chemical insecticides, application of mineral compounds was tested in a vineyard in Khalilabad region (Khorasan Razavi Province), in 2015. Treatments included kaolin (5% concentration), sulfur WP (3000 ppm), sulfur dust, a mixture of kaolin and sulfur WP, phosalone insecticide (1500 ppm), and control (water spray), respectively. Spraying times including late April, early May and mid-July, Samplings were carried out one day before and 3, 7, 14 and 21 days after spraying. At each sampling time, the total number of leafhopper adults and nymphs on 5 leaves per tree were counted. Based on the field studies, mineral compounds application reduced the leafhopper population at all spraying intervals. The mean percentage of leafhopper population reduction was observed in treatments including kaolin, kaolin and sulfur mixture, phosalone insecticide, sulfur WP, sulfur dust and control in 3 days after spraying, 89, 86, 57, 25, 25 and 3 percent, respectively, and also in 21 days after spraying, 48 , 47 , 17 , 7 , 12 and 2 percent, respectively. Therefore, kaolin (Sepidan® WP), with 5% concentration, or kaolin and sulfur mixture spray over the whole canopy of trees could be used successfully to reduce leafhoppers population on grape.

Stability challenges in Microgrids (MGs) usually arise from low inertia of Distributed Generation (DG). In this paper, a voltage stability improvement method is proposed in order to improve MG operation. Voltage Stability Index (VSI) is applied to evaluate and improve voltage stability of MGs including different types of DGs. A new hybrid optimization is introduced to find the optimal operation of autonomous MG and to improve VSI. Operational optimization is performed by finding optimal droop parameters of DGs and sitting wind DGs to reduce energy generation cost. Optimization is defined as a multi-objective function and a hybrid HS-GA algorithm is applied to solve the optimization problem. A new power flow formulation is also proposed in which the steady state frequency, reference frequency, droop coefficients and, reference voltage of droop based DGs are considered as optimization variables. Results of proposed approach are compared with other methods for 33 and 69-bus IEEE systems using MATLAB software. Results prove the efficiency of proposed approach for operational improvement of MGs.

Population growth, migration from rural, urban development and increasing vehicle creates an important topic in the name of transport and urban traffic and consequently the complexity of this issue to develop a comprehensive and integrated management of transport and traffic has become inevitable. In urban planning system, there is a direct relation between land use, physical criteria and offered supply of transportation facilities. So the aim of this research is considering physical, transportation and population criteria involved in traffic so that with combining existing indexes by using IHWP model evaluate the points having traffic potential in urmia city. This research according to its purpose is the kind of applied research and according to method of work has descriptive- analytical nature. To perform the study, 14 indicators from among the factors affecting traffic were selected and after distribution questionnaire between elites, the scores of indicators based on IHWP are calculated. Preparation and Fuzzy fiction of layers based on the relationship of indicators with research aim and according to Sigmoidal functions respectively has done in GIS and Idrisi software and finally by using Weighted Sum the combination of 14 indicators with applying their scores, is done. Transportation researches orientation to traffic modeling with sectorial and limited number of indicators and led to this research by combination of different transportation, population and physical sub- criteria evaluate the traffic congestion potential in the cities. The results show that 17 percent of urmia city area in low traffic potential, 77 percent in middle potential and 6 percent located in high traffic potential area. As a result, it can be said that much of Urmia area in terms of traffic potential is locate in average traffic zone. The results also in separation of 5 regions suggest that regions of 5, 4 and 2, 3 and 1 respectively the highest to the lowest potential in high traffic zones are allocated.

Intrusion of quartz-monzodioritic igneous bodies of Oligocene age into the Eocene lithic crystal tuffs and trachy-basalts resulted in occurrence of widespread argillic alteration zone in the Jizvan area (Tarom-Hashtjin zone). Mineralogical studies indicate that this alteration zone includes kaolinite, quartz, smectite, pyrophyllite, muscovite-illite, alunite, rutile, calcite, feldspar, chlorite, hematite and goethite minerals. Hypogene ore minerals within the silicic-carbonatic veins and veinlets of argillic alteration zone contain chalcopyrite, galena and pyrite accompanied by goethite, malachite and azurite of supergene origin. Mass changes calculations of elements with assumption of Al as a monitor immobile element indicate that elements such as Ti, P, Th, Nb, Ta, Y and Zr have suffered leaching during argillization of lithic crystal tuffs. This abnormal behaviour is in relation to low pH of altering solutions, high water/rock ratio, abundance of complexing ions and suitable drainage system. The distribution pattern of REEs normalized to chondrite shows differentiation and enrichment of LREEs relative to HREEs and occurrence of negative Eu and Ce anomalies during argillization of lithic crystal tuffs. Geochemical investigations reveal that occurrence of negative Ce anomaly (0.49-0.92) is in relation to the destruction of zircon by acidic-oxidizing fluids. Negative Eu anomaly (0.23-0.73) and mass loss of elements such as Si, Fe, K, Rb, Cs, Sr and Ba indicate destruction of plagioclase and hornblende by strongly acidic hydrothermal fluids and high oxygen fugacity of environment. The correlation coefficients between elements display the controlling role of Mn-oxides in distribution and concentration of REEs, Pb, Zn and Cu. Mineralogical and geochemical evidence such as presence of pyrophyllite, alunite and rutile, enrichment of LREEs relative to HREEs, low values of La৯, negative Ce anomaly and strong positive correlations between (LREEs/HREEs)N-LOI and (La/Lu)N-P suggest that the development and evolution of argillic alteration zone in the Jizvan area is affiliated to hypogene processes.
