The use of appropriate level of theories for studying weak interactions such as 8-8 stackinginteractions of aromatic molecules has been an important aspect, since the high level methods havelimitations for application to large molecules. The differences in the stacking energies of variousaromatic molecular structures are found significant. It is also very important for identifying the mostfavor...

Using efficient methods that reduce the search space, we design an algorithm strong enough to solve all 8×8 Hex openings.

More than 80% of the worldís population depend upon traditional medicines for various skin diseases (1). Recently, the traditional use of plants for wound healing has received attention by the scientific community (1, 2). Approximately one-third of all traditional medicines in use are for the treatment of wounds and skin disorders, compared to only 1-3 % of modern drugs (3). Wound healing is a ...

We study the possibility of prediction/decision making in a finite 2-person game with pure strategies, following the Nash-Johansen noncooperative solution theory. We adopt the infinite-regress logic EIR (a fixed-point extension of the epistemic logic KD with 2 persons) to capture individual decision making from the viewpoint of logical inference. In the logic EIR, prediction/decision making is ...

The ribose conformations of 8-azaadenosine, 8-azaguanosine, and 8-azainosine have been studied using proton magnetic resonance in ND3 solutions, in D2O solutions, and in pyridine solutions. The temperature was varied between -60 and +40 degrees C in ND3 and between +10 and +60 degrees C in D20 solutions. The analysis is based on the two state S in equilibrium N model of the ribose moiety propos...

The chemical composition of the Hydrolate of Citrus aurantium L. (Rutaceae) flowers (neroli) grown in Iran, and two commercial hydrolates were analyzed by GC/MS. Thirty compounds (90.3%) were identified in the Hydrolate by the use of laboratory apparatus, thirty-eight compounds (83.4%) in the Hydrolate from the traditional method and fifteen compounds (98.3%) in the industrially produced sample...

Background & Aim: Salvia spinosa L. is a perennial shrub and aromatic plant belongs to the family Lamiaceae. S. spinosa grows wild in some districts of Iran. The aim of this study was to identify of the chemical components of S. spinosa in Isfahan climatic conditions. Experimental: The aerial parts of the plants were collected from Isfahan province in 2014. The essen...
