Abstract: One of the most recent researches in financial field is using an Ant Colony System (ACS) in the corporate bankruptcy prediction. In this paper, the Ant Colony System is used to predict the bankruptcy of listed companies in Tehran Stock Exchange. The research findings shows that model’s prediction power is about 59% with taking into account the rations proposed by Altman (1968). After examining the causes of significant errors in model, a proposed model is introduced. This model which is based on four financial ratios fits the economical infrastructure of Iran. The results obtained from testing of the suggested model indicate that this model is able to predict the corporate bankruptcy one year prior to bankruptcy with an accuracy of 93% for large-sized firms and about 90% for small-sized ones, respectively.

A semimicroscopic analysis of a set of experimental data of elastic α + 12C scattering was performed at several laboratory energies. The Woods-Saxon parameters were adjusted to obtain the best χ2 fit to the scattering data. The energy systematics of the positions of Airy minima was constructed, and it was shown that their positions depend linearly on the inverse center of mass energy. The parameters of the model potential have been determined unambiguously. It has been shown that the energy dependence of the volume integrals satisfies the dispersion relation and agrees well with the results obtained within a phenomenological analysis. Also, it has been shown that the found positions of the Airy minima satisfy the rule of the quadratical dependence of the position of the Airy minima on the reduced mass of the colliding nuclei.

Abstract: Background: Antioxidants are combinations that protect the body against cell membranes injury or cell genetic material damage from free radical activity. Free radicals are the source of many diseases such as cancer and skin aging. Materials and Methods: In this study, thymol antioxidant activity has been compared and evaluated using three stable radical scavenging methods: 2, 2-Diphenyl-1-picrylhydrazyl (DPPH), measurement of phenolic compounds and hydrogen peroxide sweeper.Results: The study results showed that the amount of IC50 for ethanol thymol in radical scavenging method DPPH is equivalent to 0.538±0.02 μg/ml, in the phenol method, the total phenol amount is 0.36±0.06 mg and in the sweeper hydrogenated water method, it is 0.39±0.09 μg/ml.Conclusion: The value of IC50 in the three methods indicates that component factors, radical production source or scavenging reaction is performing almost with the regular grade which is dependent on Thymol concentration at a given time. The tested material has good antioxidant properties and it can be used as a natural antioxidant and in some materials as additives.

Abstract: This experiment was done for evaluation the effects of potassium humate on seed germination, yield and yield components and seed planting method to commercial used of F1 true potato seed. This research was conducted in Ardabil (Iran) during 2007 and 2008. HPS-II/67 hybrid seed 3500 were grown after treatment in seven different times by potassium humate (for 6, 12, 18 and 24 h till complete germination in potassium humate solution, till complete germination in water and without using the potassium humate and water as control). Potassium humate was used 40 mL kg-1 seed in 2 L of water. Then seeds were transferred to greenhouse and planted in peat mass bed (Biolan). During growth period were measured the traits such as start and seed germination percent and day number from planting till germination in laboratory and greenhouse. Seedlings transferred in 4-5 leaf stages to field. Experimental design was randomized complete blocks with three replications. After harvest, were measured the traits such as tuber number and weight per plant, tuber weight average per plant and tuber yield. Results showed that among different treatments of potassium humate there is significant difference for the tuber number and weight per plant, tuber weight average per plant and tuber yield. The maximum seed germination percent, tuber number and weight per plant, tuber weight average per plant and tuber yield produced in 6 and 12 h treatment by potassium humate. Direct planting of TPS in compare with the planting after seed germination in potassium humate and water caused to increase tuber yield. In this experiment, seed treatment by potassium humate for 6-12 h and seed direct planting in greenhouse percent without seed germination under in vitro, caused to increase seed germination percent and tuber yield.

Abstract: This experiment was done about suitable composition of planting bed and plantlet age in greenhouse for increasing mini-tubers number and weight per plant. This research was conducted in Ardabil in 2007 and 2008. Plantlets of potato Agria cultivar were grown under in vitro condition. Then plantlets were transferred to greenhouse in four ages of plantlets (20, 30, 40 and 50 days) on a randomized complete blocks design with four replications in greenhouse. During growth period in greenhouse, were measured the traits as plant height, main stem per plant, mini-tuber number, weight and average weight per plant and uniformity per plantlets. The results of combine analysis of variance showed that there were significant differences between years as mini-tubers weight per plant, mini-tubers average weight per plant, between plantlet age as mini-tubers number and weight per plant, mini-tubers average weight per plant and stem number per plant. Interaction of years and plantlet age were significant on mini-tubers weight per plant. Plantlets, which transferred to greenhouse after 20 and 30 days, showed higher mini-tubers number and weight per plant in compare with other ages. There was positive significant correlation between mini-tubers number with mini-tubers weight per plant and mini-tubers average weight per plant. After, the better plantlet age selected in greenhouse and plantlets age of 30 days cultured in 12 different planting beds prepared from Iran and Finland reigns on the basis of ten replications completely randomized blocks. Statistical analysis showed that the maximum number and average weight of mini-tuber per plant produced by use of three planting beds of Iran (Ardabil Neogen soil and forest peat mass with large Zeolite) and Finland (Biolan peat mass with large Zeolite).

Open Journal of Geology (OJG) , 2017, DOI: 10.4236/ojg.2017.78081
Abstract: The study area is located on the Urumieh-Dokhtar Magmatic Assemblage of Iran, in the west of Ardestan between the East longitude 52°1' to 52°18' and the North latitude 33°17' to 33°27'. Remote sensing techniques are suitable for studying the alterations occurring in the igneous terranes. The alteration zones are well illustrated by implementation of the principal component analysis and the Crosta methods and Spectral Feature Fitting on ASTER data. In order to identify the lineaments, both Landsat-8 satellite imagery and GDEM-ASTER data are used in spatial processing. Using directional filtering and automatic extraction of lineaments, a tectonic lineaments map is prepared. Then alteration maps, tectonic lineaments map and 1:100,000 geology map are used to identify areas with high potential of Cu mineralization.
