In this paper, a new approach is proposed for optimal bidding of strategic units in day ahead energy market and market clearing process. This method describes the multi objective scheduling of strategic units that is going to maximize its profit in presence of rivals and minimize its emission. In order to achieve this goal, a bi-level mathematical optimization model with equilibrium constraints Is provided. The first level maximizes the profit of strategic units and the second level maximizes the level of social welfare. The bi-level model is converted to a mixed integer linear programming model using a duality theory and Karush-Kuhn-Tucker (KKT). Another goal is to solve the bi-level problem in a multi-objective method using augmented Epsilon constraint method in order to maximize profit of linearized model and reduce the emission of strategic units. Finally, the best answer is selected using fuzzy decision method. The power transmission distribution factor (PTDF) method has been used to model the network structure.

One way of detecting ships or submarines is the observation of magnetic field signature around the object. Ships or submarines can be assumed as a collection of closed circuit of electrical currents. The electrical current of each close circuit must be properly regulated. The main purpose is production of a magnetic field equal to the magnetic field around the ship but with the opposite direction. By using this method, the magnetic field can be effectively reduced. This simulator is designed in C# language and it was named General Magnetic Compensation. The inputs of this software are geometry, location and magnetic field and the output is electrical currents of each closed loop, thus making the magnetic field reduced around the submarine. Accuracy and validity of the new software was investigated by analytical relation of magnetic field for proper geometry. Then a submarine was simulated in COMSOL and data of this simulation were used in General Magnetic Compensation software. The results were in great agreement with the results of the COMSOL software and could predict the magnetic field well.

Ficus religiosa has great mythological, religious, and medicinal importance in the culture of India and Nepal since times immemorial. The present paper was done to evaluate the potential of sodium hypochlorite in controlling the contamination of F. religiosa micro-propagation and seed germination of F. religiosa. In this study, a factorial experiment based on a completely randomized design with 18 treatments including six different sodium hypochlorite concentrations (0, 5, 10, 15, 20, and 25 %) and three soaking time of explants (5, 10 and, 15 min) with three replications was conducted. The seeds were inoculated on one-tenth strength of MS (Murashige and Skoog, 1962) medium. The lowest rate of contamination (0%) was obtained in treatments containing 20% Sodium hypochlorite at 10 and 15 min immersion and 25% Sodium hypochlorite at 5, 10 and 15 min immersion. The highest seed germination (63.33%) was observed in treatments including 10% Sodium hypochlorite at 5 and 10 min immersion.

Survey the performance of equipment and devices in the industry and is subsequently environmental hazards identify is one of the requirements of environmental risk assessment in the rolling industry. This study, Identificated environmental hazards with the "What if?" Technique in the hot rolling process and risk assessment by William Fine.
After the grouping of equipment in the Hot-rolling hall kavir steel industry, the environmental risks are considered according to ISO 14001 approaches (such as emissions to air and water, energy consumption, depreciation of equipment and so on ), According to "What if?" Technique , during the field visit was identified. Then expert team carried out the initial risk assessment by William Fine method and proposed the Corrective revisions and Calculated RAC2. Data analysis was performed using SPSS version 19.
280 environmental risk of the proper and defective equipment's function was identified that the most number of risks associated with production machinery (2/29%) and mechanical equipment (2/24%). Most of the identified environmental risk (21%) related to the creation and distribution of waste and emissions into the air risk(5/18%) and risk of corrosion and depreciation of equipment was lowest percent (5/2%). Most of the risk related to the creation and distribution of waste (73%) and the lowest risk is corrosion and depreciation of equipment(1).
establishment of the comprehensive environmental management relying on equipment continuous monitoring in the rolling industry in format of the maintenance program in order to prevent the creation of technical defects affecting the environment an important role in the control of emissions to the environment will be affected by this industry.

Bodhi tree (Ficus religiosa) is a long-lived valuable multi-purposed forest tree. The tree is exploited due to its ornamental and medicinal value and is used in religious ceremonies. The propagation rate in natural habitat is low. The current study was conducted to investigate the effects of ascorbic acid, phloroglucinol and activated charcoal in controlling callus browning and shoot multiplication in in vitro culture of Ficus religiosa plantlets using callus from leaf segments. The treatments included various concentrations of ascorbic acid (500 and 1000 mg/l), phloroglucinol (100 and 200 mg/l) and activated charcoal (2 and 4 g/l) added to the basal MS medium supplemented with 1.0 mg/l BAP along with 0.1 mg/l IBA. The culture medium containing 1000 mg/l of ascorbic acid controlled callus browning effectively. In this medium the least number of sub-cultures (2-3) were carried out. The highest regeneration frequency (100%), the maximum number of multiple shoots (5.56) and the highest number of subcultures (11.33) were obtained on basal medium supplemented with 200 mg/l phloroglucinol. Finaly, the results of the current study revealed that production of phenolic compounds of explants was significantly controlled by incorporating higher levels of ascorbic acid and activated charcoal into the culture medium.

Present paper deals with the phenomenon known as self-sustained nuclear fission wave that is set up with establishment of the U-Pu cycle in a fast nuclear reactor. The safety arised from self sustained state of the wave and also 50%the possibility of initiation and evolution of the wave, the system comprised of neutron diffusion equation coupled with burn-up and kinetic equations have been considered. The linearizationmethod used to solve this systemnot only separates diffusion subsystem from reaction one but also simplifies greately dealing with several real hundred days of simulation. Space and time discretizations of the linearized diffusion subsystem were performed by 3D finite element and crank nicolson methods, respectively. The convergence of equation was carried out using the iterations based on the optimized BiCGStab(L) method. Rung-Kutta (5) method was used to solve the first order differential equations of the reaction subsystem since the concentrations of elements in the reaction subsystem changed slowly. Using the element by element FEMand BiCGSta (L) used for solving the systemdropped the required memory down to 1/10. Considering the long period of the simulation, 3D case of the problem and heavy computations, the OpenMp method was used to parallelize the code written in FORTRAN 95.
