This paper introduces a new approach of firefly algorithm based on opposition-based learning （OBFA） to enhance the global search ability of the original algorithm. The new algorithm employs opposition based learning concept to generate initial population and also updating agents’ positions. The proposed OBFA is applied for minimization of the factor of safety and search for critical failure surface in slope stability analysis. The numerical experiments demonstrate the effectiveness and robustness of the new algorithm.

A new hybrid optimization algorithm was presented by integrating the gravitational search algorithm （GSA） with the sequential quadratic programming （SQP）, namely GSA-SQP, for solving global optimization problems and minimization of factor of safety in slope stability analysis. The new algorithm combines the global exploration ability of the GSA to converge rapidly to a near optimum solution. In addition, it uses the accurate local exploitation ability of the SQP to accelerate the search process and find an accurate solution. A set of five well-known benchmark optimization problems was used to validate the performance of the GSA-SQP as a global optimization algorithm and facilitate comparison with the classical GSA. In addition, the effectiveness of the proposed method for slope stability analysis was investigated using three ease studies of slope stability problems from the literature. The factor of safety of earth slopes was evaluated using the Morgenstern-Price method. The numerical experiments demonstrate that the hybrid algorithm converges faster to a significantly more accurate final solution for a variety of benchmark test functions and slope stability problems.

This paper deals with the economically optimized design and sensitivity of two of the most widely used systems in geotechnical engineering: spread footing and retaining wall. Several recent advanced optimization methods have been developed, but very few of these methods have been applied to geotechnical problems. The current research develops a modified particle swarm optimization (MPSO) approach to obtain the optimum design of spread footing and retaining wall. The algorithm handles the problem-specific constraints using a penalty function approach. The optimization procedure controls all geotechnical and structural design constraints while reducing the overall cost of the structures. To verify the effectiveness and robustness of the proposed algorithm, three case studies of spread footing and retaining wall are illustrated. Comparison of the results of the present method, standard PSO, and other selected methods employed in previous studies shows the reliability and accuracy of the algorithm. Moreover, the parametric performance is investigated in order to examine the effect of relevant variables on the optimum design of the footing and the retaining structure utilizing the proposed method.

The nanostructures of zinc chromite（Zn Cr2O4） were fabricated by the microwave method. It was shown that the well-crystallized spinel structure is formed after annealing at 700 °C. The influence of reaction time and irradiation power of oven on the size and shape of the as-prepared Zn Cr2O4 samples was studied. The synthesized samples were characterized by X-ray diffraction（XRD）, scanning electron microscopy（SEM）, energy dispersive X-ray（EDX）, transmission electron microscopy（TEM）, diffuse reflectance spectroscopy（DRS）, photoluminescence（PL） spectroscopy, Fourier transform infrared（FTIR） spectra and vibrating sample magnetometry（VSM）, respectively. The optical band gap calculated using DRS was found to be 3.50 e V for Zn Cr2O4 nanostructures. Photoluminescence measurements also confirmed this result.

Objectives： To review the calendar, mortality and morbidity of Iraq-Iran chemical war among Iranians based on researchers＇ reports. Methods： We used national and international databanks such as PubMed, ISI, Scopus, Irandoc and Iranmedex and studied 350 articles related to chemical agents and their effects on different organs. The main criteria for qualification of articles were relevancy orientation and being published in approved medical journals. Results： The Iraqi army invaded to west and southwest Iran using chemical weapons such as nerve agents （NAs） and sulfur mustard （SM）. Most victims were civilians including women and children. These attacks had imposed more than 150 types of diseases and complications on Iranians and the frequency of death was 2%-3%. Most reports were about respiratory problems and a few were in the domain of socio-economic damages Conclusion： At present, 25 years after me end of war, the victims are faced with different complications induced by chemical agents and it is estimated that they will be continuously troubled by these problems in future.

Early Permian deposits in north of Kalmard region recognize with formal group of Khan;they have various features in the different place. This group includes four different formations from lower to the upper part: Chili, Sartakht and Hermez. These formations consist of carbonate rocks. Chili Formation has 104 m, thickness in Darin section and consists of limestone with intermediates of shale and marland sandstone. Lower boundary of this formation is disconformable with Gachal formation. The upper boundary is separated by unconformity from the upper part Sartakht formation according to the lithological characters and microscopic studies, cause identifications of beach, intertidal, open and semi-restricted lagoon, shoals and bar and open marine sub-environ- ments for the Chili Formation. Vertical changes of microfacies and depth changes curve show much more thickness of shoals and bar microfacies, and little thickness of open and semi-re- stricted lagoon and open marine microfacies. Deposits of Chili Formation in Darin section deposited in the gentle gradient Homoclinal ramp in the south of Paleotethys Ocean. Two depositional sequences have been identified in this formation, based on recognized Fusulinid, show age of Sakmarian, which has adaptation with Lower Absaroka III.
