In the wake of Jacobs’s criticisms of planning, planners increasingly felt a level of angst over, or even responsibility for, the condition of the city. Schooled in preparing and implementing plans and land use regulations, they appreciated the appeal of a new movement that offered a simple, tangible, and marketable recipe for practice. New urbanism theory is one of the contemporary urban theor...

the philosophical-theosophical theory of “the first designation” is macro-theory about instant of “phenomenon existence” and the formation of emanation of multiplicities from the unique. this subject is one of fundamental and hardest problems in “islamic mysticism”. since ibn-arabi is the father of theoretical mysticism in islamic world and so his view about one-ness existence is the foundation...

tetrazole-containing compounds have been the subject of much recent research because of theirpotential as high energy density materials (hedms). in this work, theoretical studies on the 1htetrazolylderivatives of tetrahedrane were done at the density functional theory (dft) method withthe 6-31g(d) basis set without any symmetrical restrictions in order to find the structural andenergetically pr...

feminist critical discourse analysis is an approach distinguished by its focus on revealing unequal power relations between women and men in their social life. in the present paper, it is suggested that simone de beauvoir’s theory of the formation of gender identity and female subject in the second sex provides a meaningful theoretical ground to the feminist critical discourse analysis. althoug...

in this article, theoretical studies on the selective complexation of the halide ions (f¯, cl¯ and br¯) and ion pairs (na+f¯, na+cl¯ and na+br¯) with the cyclic nano-hexapeptide (cp) composed of l-proline have been performed in the gas phase. in order to calculate the dispersion interaction energies of the cp and ions, dft-d3 calculations at the m05-2x-d3/6-31g(d) level was employed. based on t...

In this work, the electronic properties of BP and CSi Nano cones have been investigated by self-consistent reaction field (SCRF) method in water solvent at B3PW91/6-31G (d,p) level of DFT theory for study of  for interactions of 5-Fluorouracil Anticancer Drug with theses Nano cones. The percent of change of energy gap (%ΔEg) shows that the complex formation of 5-Fluorouracil with BP ...
