A Stanene, is a two-dimensional material composed of tin atoms arranged in single hexagonal layer, manner similar to graphene. First principle studies based on density functional theory were performed investigate the effects hydrogenation and Al/P doping electronic structure magnetic properties stanene. Hydrogenation opens bandgap stanene changes it from nonmagnetic ferromagnetic through H 1s s...

This paper tests how important the time value of money (TVM) principle is in decision making real-life conditions, when different selection criteria can be considered. A three-stage survey was administered to students from a Romanian university economics. They were asked choose between two cars. These cars have equal total cash outflows but present values. The benefits using them not specified,...

Catharanthus roseus is widely cultivated around the world.  Cold atmosphere plasma (CAP) has been used to improve crop plants seed germination, and plant growth. In the present study, three different times of CAP (40, 50 and 60s) were used for the treatment of C. roseus seeds, and the changes in morphological traits, antioxidant enzymes and the genetic content of the treated plants were examine...

the principle of formality –free protection is an international principle in the copyright and it was stabilized in the berne convention. but this principle has not been studied in iran and evaluation of the principle is very vital because easier access to the works and fair trial. recent paper has attempted to study this principle in light of the berne convention and analyzes and interprets th...

During the in situ leaching process of ion-adsorption rare earths, solution needs to be constantly injected mine slopes. As a consequence, landslides are highly likely occur due increasing water level soil mass. To solve this problem, we conducted mechanical analysis on rising after injection, which shed light principle slope instability brought about by level. With variation as major factor, e...
