In addition to accounting based evaluation model, there is an economic model, which focuses on cash flows rather than profit. One of these models is the “cash recovery rate” based on which the economic rate of return can be estimated. In this article, the relationship between accounting measures of performance evaluation(Return On Assets, Return On Equity, Return on Sales) and value-based measures(Economic Value Added and Market Value Added) in relation to cash recovery rate, which is as proxy of economic performance of companies, has been investigated. As many as 60 sample companies between the periods of 1382 to 1386 have been selected. The achieved results from empirical tests indicate that the return on assets, return on equity, return on sales and market value added are positively and directly related to the cash recovery rate. They can be used as a reliable measure in the performance evaluation in spite of economic value added which lacks information content. Manuscript profile -

ISPs are seeking customers by offering highly competitive packages. Undoubtedly, a focused approach to establishing the strengths and unique competitive edge of a company is essential for survival given the intense competition. ISPs must create a powerful relationship between Internet and user. Relationship quality is a general assessment of relationship strength and the extent to which a relationship meets the needs and expectations of the parties involved based on a history of successful or unsuccessful encounters or events. This research presents two models of relationship quality that evaluate the indirect influence of relational sellin behavior, network quality, and service recovery on ISP customer loyalty through satisfaction and trust and how prior IT experience moderates the above relationships in ISP services. Data was obtained from questionnaires distributed to ADSL customers of the largest ISP in Iran. The results found that relational selling behavior, network quality, and service recovery indirectly influence loyalty through relationship quality. The effects of relational selling behavior on satisfaction are stronger for inexperienced customers. Manuscript profile -

To conduct this research in the west of Giulan province (Shanderman area), three skid trails with 10 years of age and slope classes: 0-10, 10-20 and 20-30% were selected. A total of 30 microplots (2x2 m2) were determined on skidtrails and adjacent areas (control area), and in them, the type of species and the frequency of regeneration were recorded 100%. In the soil sample taken from a depth of 0-20 cm, Bulk Density and Particle Density and %Porosity were measured. The results showed that there is a significant difference between skidtrails and the control area in terms of bulk density, percentage of soil porosity and species regeneration (p<0.05). The frequency of regeneration of the Acer velutinum species in the skidtrails was significantly higher than in the control area, and the frequency of the regeneration of the Carpinus betulus and Acer capadosicum species in the control area was significantly higher than that of the skidtrails. However, no significant difference was observed between these two places in terms of the regeneration of Fagus orientalis and Alnus subcordata species. There was no significant difference between the three slope classes investigated in terms of regeneration and bulk density, the percentage of soil porosity of skidtrails with two slope classes of 0-10 and 20-30% did not have significant differences (p>0.05). The result is that the time period of 10 years is not enough to recover the physical properties of the soil and establish the regeneration of the skidtrails in this area, and the slope of less than 30% does not have a significant effect on the recovery of the soil and the regeneration of the skidtrails.

Flotation tailing should be reused judiciously because of its negative effects on the environment caused by building up of these industrial wastes in surroundings. Material and Methodology: The leaching experiments have been carried out in a stirred stainless-steel tank, at a constant temperature of 25oC. Sulfuric acid with 98% purity was used as a solvent in the leaching process. The weight of flotation tailings used in experiments was 18 kg. Using various amount of water, different pulp density was achieved. The experiments were done with solid weight percentages of 30%, 35%, 40% and 45% in water. Findings: The results of this study revealed that suddenly addition of acid to the tank due to sudden change of acid concentration caused to increase the efficiency of the leaching process. When acid was added to pulp suddenly, dissolution of iron from tailings was lower than that in gradual addition of acid condition. Solid particles residence time are less due to sudden addition of acid condition. Discussion and Conclusion: The amount of consumed acid in the experiments varied from 31 to 54 kg/t with respect to pulp density. According to experimental conditions, sample contained 40% solid, as appropriate feed for recovery of copper from flotation tailing was recommended. For a solid percent of 40wt% and residence time 15 minutes, copper recovery reached 92.67%. Manuscript profile -

When this kind of wastewater, which includes heavy metals from miscellaneous industrial activities, enters to environment prepares adverse effects on human beings and food chain organisms. There are many investigations about heavy metals removal from industrial wastewater based on precipitation, ion exchange, and biological processes. However, these days, the performance of membrane processes such as nanofiltration is focused as an appropriate process and many investigators are working on it. The main purpose of this work is the evaluation of nanofiltration process on heavy metals such as nickel, chrome, and cadmium from synthetic industrial wastewater. Also, the effects of operating parameters on nanofiltration process are investigated. In this work, a nanofiltration pilot with capacity of 40 m3/day, which consists of I and 5 micron filters and a permeable polyamide membrane (NF90- 4040), is used and the effect of heavy metals concentration increase on the removal efficiency of one or mixed of all heavy metals are evaluated. It is concluded that the performance of nanofiltration with increase of heavy metals concentration improved and the maximum heavy metals removal efficiency is occurred when the concentration of heavy metals is equal to 100 mg/L. The average removal efficiency of one and mixed of all heavy metals is 95.4 and 97.5%, respectively. Moreover, the operating pressure of nanofiltration process with increase of heavy metals concentration, decrease but the recovery rate of membrane increase. The average recovery rate of membrane in one and mixed of all heavy metals removal condition is 72.8 and 72.4%, respectively. Also, among the heavy metals the maximum recovery rate and the minimum operating pressure in nanofiltration process belong to cadmium. Manuscript profile -

At the present time, power plants play a major role in the production of greenhouse gases and the optimization of the systems of the newly-constructed power plants is one of the country’s main environmental challenges. Therefore, the assessment of the construction of energy recovery systems aiming at increasing the efficiency of gas power plants with little pollution can be a great help to the environment. In this study, a techno-economic evaluation of energy recovery systems has been done in Kerman power plant considering air pollution reduction. Fortunately, the potentials for the construction of combined cycle power plants exist in the country. Since such power plants save the fuel and increase the efficiency, they can reduce contaminating gases. The application of energy recovery systems in gas power plants is quite economical and their pay-back rate is 9-10 years. The results of the present study show that with these plants, 152 million liters of gas-oil and 58.3 billion cubic meters of natural gas will be saved over a period of 30 years. As a result, 1.652 million tons of greenhouse gases will be reduced. Manuscript profile -

Its’ high discharged air temperature, limits the application of a cost effective dust collector. The application of a heat recovery system seems not only to make it possible for application of a cost effective dust collector but also may reduce heating costs considerably. In the present study, the air pollutants discharged from a fiberglass furnace flue were measured and evaluated. In the next step, the reduced fuel and social costs were estimated if a proposed heat recovery system was applied. For this purpose, five air pollutants including CO, CO2, NO, NO2, NOx, and air velocity were measure using TESTO 350XL. Particulate matter (PM) was also monitored using TCR TECORA ISO TRACK, all through direct readings. Temperature was monitored automatically through installed instrumentation at the furnace control room. More than nine hundred thousand air temperature readings were screened to select 2043 reliable readings. The recovered heat was estimated using the measured data. Direct and indirect savings from the recovered heat was predicted using the Environmental software. The results revealed that the average concentration of CO, NOx, and PM were respectively 1.45, 1.38 and 6.477 times higher than environmental permissible limits. The recovered heat was equivalent to almost 1500 million cubic meters of natural gas saving per year which costs 24.4 million US$. The extraction of statistic data and research hypothesis test was done by Mini Tab 14 software. The data of mean society examination (with determined variance) and mean of two societies and also probability plot used for contaminant changes forecast in the next years. Manuscript profile -

However, several technical challenges are common in the high penetration of RES and wind farms (WF). The most important challenge is to achieve frequency stability in new systems. Because WF provide less storage, power compared to synchronous generators. In addition, due to the connection of wind farms to the AC grid through electronic power converters, new power systems have little inertia and WF cannot participate in frequency regulation with other conventional production sources in normal operation. Recently, with the increasing expansion of wind farms in power systems, their participation in supporting and stabilizing the frequency in the event of disturbances in the production or consumption of power systems has been highly considered. Therefore, in this research, firstly, it investigates the way of simulating the inertia of synchronous generators in wind turbines in order to increase the inertia of power and frequency control systems. Then, a review of various strategies and the latest developments in the field of solving the challenges of the presence of wind farms in the direction of temporary frequency support in power systems has been done. Finally, the studies conducted in inertial control techniques and system frequency for variable speed wind turbines have been investigated, categorized and compared. Manuscript profile -

Most commercial simulators solve the equations governing reservoir behavior with the finite difference approach. To solve the three-dimensional equations of flow in a porous media with the finite difference method, the grid dimension has an effect on the simulation results (i.e., divergence). In addition, the simulation of complex reservoirs with a large number of network blocks needs a long computational time. In order to eliminate the effect of block size and increase the speed of simulation, the streamline method has been proposed, which is widely used in the management of hydrocarbon reservoirs. The streamline method can monitor the flow direction in the reservoir, injection efficiency, pore volume, and well allocation coefficient to determine the volume of fluid transferred between injection and production wells. Also, in recent years, many studies have been conducted on the effect of nanofluid injection on the characteristics of oil reservoirs and the increase in oil recovery. Since the streamline method has not been used to simulate the nanofluid injection in oil reservoirs, in this research the effect of water-silica nanofluid injection on the flow equations of phases has been investigated. The simulation results showed that nanofluid injection into the reservoir is more effective than pure water injection and increases oil production. Moreover, it was observed that the reservoir oil type (light and heavy) has an insignificant effect on the simulation results. Manuscript profile -

Due to the reduction of fossil fuels, their growing need for communities to energy price increases, the phenomenon of thermoelectric waste heat recovery and recycling in various parts of the human body can be used. Different parts of the body have different temperature, an average temperature of the body is mainly about 37.5 ° C is accepted, but an average temperature of about 32° C is the skin. Since the temperature of the skin over the ambient temperature is the temperature difference, the thermal energy contained in the skin can be used to generate electric power using heat recovery can be used. Electric power generation in the absence of the temperature difference between the body and the environment is poor, but through optimization heat sink recycling device can be improved output voltage The advantages of thermoelectric technology can be clean and quiet, the lack of mechanical parts, simple maintenance, low weight and long life that is nearly 100 thousand hours mentioned. The aim of this study was to investigate the feasibility of thermoelectric modules to produce power from heat output is human skin. The results of the modeling show that the temperature difference across the thermoelectric more electrical power will increase. Manuscript profile -

Energy supply is one of the most basic prerequisites for social development and economic growth of many societies, especially developing countries, and access to economically sustainable and environmentally friendly energy sources seems necessary in today''''s conditions. The decrease in fossil resource reserves and the increase in the price of oil and its products, as well as the need to pay attention to the reduction of environmental pollution caused by fossil fuels, have encouraged the countries of the world to use renewable and clean energies. Biofuels are one of the renewable resources that have attracted the attention of many European and American countries. Substitution of fossil fuels with biofuels has the potential to reduce some of the adverse environmental impacts of fossil fuel production and use, including emissions of conventional pollutants and greenhouse gases, depletion of finite resources, and dependence on unstable external suppliers. In addition to environmental benefits, the use of suitable biofuels can bring economic benefits such as reducing agricultural surplus reserves, reducing unemployment and dependence on imported oil, rural development, sustainable agriculture, etc. In the current study, after introducing and expressing the characteristics of two common biofuels, biodiesel and bioethanol, the general advantages and disadvantages of using biofuels, the economic, social and environmental considerations of using biofuels have been discussed.

There may be a major dispute over the length of the trial due to sei­zure and detention, what is the point in this regard to what extent is the li­nk­ that has been created between the main and the reciprocal of the dispute? Therefore, in this research, we will examine the effect of the deconstruction and seizure of the proceedings in the main dispute as to the mutual dispute raised during the main pro­ce­ed­ings. Due to the fact that the seizure and the decay of the proceedings to protect the rights of the parties to the lawsuit and the observance of the rights of defense of the parties to the lawsuit are also part of the rules of procedure, the existence of this longing is necessary. The result is that the loss of the main claim may result in the recovery of the cl­aim, the extradition of the petition, the decline of the right, the reco­nciliation between the parties and the change of court. These cases have been explicitly mentioned by the legislator in French law.

The aim of the present research is to investigate the deformation behavior of Ti-3873 alloy via warm compression test. For this purpose, compression test has been conducted in the temperature range of 650-850 °C and strain rates of 0.001,0.1 and 1, 1 s-1 at dual phase α/β and single phase β regions. The test was continued up to plastic strain of 0.7. For establishing the relationship between the microstructure and flow behavior, the initial and subsequent microstructure of the specimens after warm deformation was studied via optical and scanning electron microscopes. The microstructural evaluation and flow curves revealed that dynamic recovery and partial continuous dynamic recrystallization were the dominant restoration mechanisms. The results showed that softening has been increased in the temperature range of 800-850 °C and strain of 0.001 and 0.1 s-1 which is confirmed by the activation energy calculated from the sinus hyperbolic equation. The activation energy for dual phase α/β and single phase β regions are determines as 429 kJ/mol and 353 kJ/mol, respectively. The higher value of activation energy for α/β dual phase region is attributed to dynamic globularization of α lamellas. The preferable regions for hot workability of the alloy were achieved at the temperature range of 800-850 °C and strain rate of 0.01-0.001 s-1 corresponding to the peak efficiency of 39% in the processing map.

Therefore, the need to provide an accurate model based on the actual behavior of the system has considerable importance. In the case of inverter-based microgrid, due to the lack of sufficient synchronizing torque, the design process must be carried out with the utmost precision. In this paper, the stability of the inverter-based microgrid will be studied. First by presenting the equations of the microgrid components its state-space model is obtained and in the presence of the static load model the stability of the system will be investigated. Then, by placing the inventory of dynamic exponential recovery and static polynomial load models, the results of the static model-based design are investigated. In this study, the measure of system stability will be eigenvalue plots and system performance. In order to achieve system stability and performance improvement, the state variables participation factors extracted and the effective parameters will be studied Manuscript profile -

Molybdenum sulfide as main catalyst plays a key role in the process of upgrading heavy oil. Therefore, recovery of this metal is very important due to the reduction of molybdenum ore resources and also the high consumption of these types of catalysts. In this study, molybdenum is recovered from a spent homogeneous nanocatalyst in the hydrocarbon process from heavy hydrocarbon feed. Platelet-Borman design method was used to determine the effective parameters in molybdenum recovery. Seven quantitative and qualitative parameters including leaching and oxidation temperatures, leaching and oxidation times, type of leaching material, sodium carbonate, and ammonium carbonate concentrations were selected. To estimate the relative importance of each parameter, two methods of Pareto charts and half-normal plots were used. Pareto charts showed that the type of leaching material, sodium carbonate concentration, and oxidation temperature affect the efficiency. The deviations in the half-normal chart also confirm the results in the Pareto chart. Accordingly, in the oxidation step with hydrogen peroxide, 25 °C and time of 60 min and in the leaching step, sodium carbonate as a leaching material with a concentration of 90 wt.%, 25 ºC, and time of 60 min can be selected for optimal conditions.

Suitable selection and predicting the performance of pure alumina Claus catalysts in view of the diversity of manufacturers and the high consumption is an important issue in the efficiency of Claus process. In this paper, catalysts were taken and their physical, chemical, and microstructural properties were evaluated by X-ray diffraction, scanning electron microscope, nitrogen and mercury adsorption, mechanical resistance etc. According to the results obtained from the study of the properties, the presence of active alumina phases and sodium impurity up to 2500 ppm, the lack of boehmite phase and others impurities like silica and iron oxide, good distribution of pore volumes for increasing active surface area and free access to the reaction zone are important properties. These properties lead to a longer life for the catalyst. The high attrition and mechanical resistance with maintaining proper distribution of pore volume and low density are important characters for the catalyst selection. Nanostructured catalysts have suitable properties. Manuscript profile -

It is very important to understand bacterial performance in relation to materials with different mineralogy in order to select appropriate bacteria and improve bioleaching processes with high performance. As a consequence, the aim of this study is to investigate the effect of smelter dust and flotation concentrate mineralogy on copper recovery from the materials using mesophilic bacteria. Materials and Methods: The effect of processing material mineralogy on biological extraction of copper was investigated using a couple of material with different mineralogy, metallurgical dust and concentrate of Sarcheshmeh copper complex. Bioleaching experiments were performed by using mixed culture of A. ferrooxidans, A. thiooxidans and L. ferrooxidans from Sarcheshmeh Copper Mine in shaker utensils. Results: Metallurgical dust mostly contained secondary sulphides products such as chalcocite and covellite, and concentrate mostly contained primary sulphides product such as chalcopyrite. The extraction rate of copper was achieved 0.835 g/L/day and 0.403 g/L/day from dust and concentrate, respectively. Also, kinetic studies showed that the rate constants of dust and concentrate were 0.125 day-1 and 0.010 day-1, respectively. Conclusion: The impact of mineralogical characteristics of the material on bioleaching operations was significant. Due to highly solubility rates of secondary sulphides, recovery rate and a higher overall copper recovery was obtained from dust in comparison to concentrate. Chalcopyrite oxidation was stopped at relatively low amounts (about 44%) and additional bioleaching time have not been improve it. The experiments showed that standard mesophilic culture at 35 ° C was very successful in bioleaching of secondary sulfide minerals, but bioleaching of primary copper sulfide minerals especially chalcopyrite by the culture was not effective.

In cutting of irrigation at mid-flowering and band application of P, RGS had the highest biological yield (12435 hg/ha). Common irrigation had the highest (11.02 kg/ha) and cutting of irrigation at mid-flowering had the lowest (5.95 kg/ha) P absorption amount. Overall, P recovery efficiency in broadcast and band application methods of P was 1.09% and 1.38%, respectively. RGS cultivar compared to Sarigol had maximum grain yield under cutting of irrigation at mid-flowering (3830 kg/ha) and mid-silique formation conditions (5428 kg/ha). RGS had the highest rate of assimilate remobilization under cutting off irrigation at mid-flowering and band application of P and it can prevent a further reduction in grain yield when exposed to late season water shortage.

67 - Continuous electrowinning of nickel from dilute sulfate solutions
Alireza Zakeri Amirreza Sheikh KaramiSignificant amounts of nickel products used in different chemical processes and general applications leave them a valuable source of nickel at the end-of-life. Production of nickel from secondary sources is generally performed through hydro-electrometallurgical methods. MoreSignificant amounts of nickel products used in different chemical processes and general applications leave them a valuable source of nickel at the end-of-life. Production of nickel from secondary sources is generally performed through hydro-electrometallurgical methods. The resulting solutions from treatment of secondary nickeliferous resources are generally of low Ni concentration and electrowinning of them is challenging, particularly since Ni concentration in commercial operations is usually more than 80 g/L. In this paper, the continuous electrowinning of nickel from dilute sulfate solutions has been investigated. The effects of four variables of temperature, specific flow rate of electrolyte, current density, and nickel concentration on current efficiency and specific energy consumption were studied by a two-level full factorial design. From the statistical analysis of the results, it was found that current efficiency increases by rising all variables, while specific energy consumption decreases with specific flow rate of electrolyte, current density, and nickel concentration. By using the obtained statistical models, the optimum conditions to achieve a nickel deposit with high current efficiency as well as lowest energy consumption are determined to be 55 °C of temperature, 3 A/dm2 of current density, 3 h−1 of electrolyte specific flow rate, and 30 g/L of nickel concentration.

They were randomly selected as a sample after successfully passing the lifeguard entrance test of 200m breaststroke less than 4 minutes in a time interval of 48hr in three days attended to participate in the games of 200m of frontal crawl with maximum intensity every day. Then, they performed one of the three protocols of Cold-Water Immersion (with 12°c), anodal stimulation (with the current intensity of 2mA), and anodal stimulation (with the current intensity of 1mA) for 15 minutes. The ratings of perceived exertion and feelings of swimmers were recorded using each recovery method by TQR and RPE questionnaires. To measure the effectiveness of the studied methods, the participants repeated 200m breaststroke with maximum intensity. To analyze the data, a dependent t-test, analysis of covariance was used.The results indicated that swimming performance significantly improved the TDCS group (with the current intensity of 2mA) (P = 0.001). The suitable current intensity of TDCS to affect reducing central fatigue and also recovery quality was better in the cold-water immersion group, and it could refer to the increase of venous return and excretion. In addition, the recovery quality was better in the cold-water immersion, and it could refer to the increase of venous return and excretion. Manuscript profile -

Putin sought to regain power by adopting the policy of pragmatism and the strategy of the normative great modern power; However, the path to regaining power since 2014 has been accompanied by regional obstacles, which have manifested themselves in two general categories: the crisis in Ukraine and the Crimean peninsula, and the leverage of Russian gas exports to Europe. In this study, we sought to understand the regional obstacles to regaining power in the Russian Federation during Putin's second term from 2014 to 2019, from the perspective of defensive realism theory. The research method was descriptive and library studies. The study found that Russia was facing obstacles in regaining its power, such as the Ukraine crisis, NATO's expansion to the east, the deployment of a missile defense shield, leverage to export gas to Europe, and the issue of EU energy security.

Unemployment of too many workers and factory closures have led marketing managers to consider and examine today's economic conditions and consumer behavior as well as examining the variety of marketing and make the conclusion that revival of some out of date brands is more economical than creating a new brand. In this research, we have tried to identify the best and most effective marketing among these marketing strategies in the revival of the brand by examining three viral, sensory and direct marketing. In fact, this research reviews the views of consumers of home appliances in Tehran based on the components of each marketing indicator: information dynamics, social relationships, trust in advertising, attitude towards advertising, sensory perception of advertising, brand loyalty, advertising flexibility and its interaction with the consumer to identify the most effective factors.
