in this research, we have studied the structural propenies of water. methanol and ethanol surrounding snidewalledcarbon nanotube (swcnt) and mixed of them either and we have investigated the solvent effects onthe relative energies and dipole moment values by ming molecular dynamics simulation. we used differentforce field it, deterrnaned energy and other type of geometrical parameters, on the p...

efficiency of enzymes which are used in industrial or environmental applications is highly dependent on their thermal stability. in this study, the stability of dfpase has been evaluated after introducing disulfide bonds to the structure. the results obtained from a series of protein design software were subjected to molecular dynamics simulation at different temperature to test the performance...

this paper deals with leader-following and leaderless consensus problems of high-order multi-input/multi-output (mimo) multi-agent systems with unknown nonlinear dynamics in the presence of uncertain external disturbances. the agents may have different dynamics and communicate together under a directed graph. a distributed adaptive method is designed for both cases. the structures of the contro...

This paper presents a robust fractional order controller for flexible-joint electrically driven robots under imperfect transformation of control space. The proposed approach is free from manipulator dynamics, thus free from problems associated with torque control strategy in the design and implementation. As a result, the proposed controller is simple, fast response and superior to the torque c...

copepods are the main zooplankton assemblages in most tropical and semi-tropical estuaries. in this research, copepod population dynamics were investigated in helleh river estuary, persian gulf during four seasons beginning from summer 2011 to spring 2012.  samples were taken using plankton net with mesh size of 140 µm and vertical towing from 5 fixed-stations in mid-season. results showed that...

medicinal chemistry depends on many other disciplines ranging from organic chemistry andpharmacology to computational chemistry. typically medicinal chemists use the moststraightforward ways to prepare compounds. the validation of any design project comes from thebiological testing.studies of the binding site of vinblastine by a single cross—linking experiment identified it asbeing between resi...
