the methanolic extract of the aerial parts of salvia leriaefolia (labiatae) afforded 5-hydroxy-4´, 6, 7-trimethoxy flavone (salvigenin) and (5,4´-dihydroxy-7-methoxy flavone (genkwanin). the structures of the isolated compounds were elucidated using 1 and 2 d-nmr, ir, uv and ms.

a solution technique for the dynamic analysis of asymmetric base-isolated buildings, subject to earthquake ground motion, is presented. to develop the formulation, a yield surface as a function of both shear force and torsion moment of the sliding surface with rigid perfectly plastic behavior is constituted. to achieve the objective, the yield stress is defined by the friction coefficient throu...

this paper describe the three dimensional finite element modeling and buckling analysis ofconventional pallet racking system with semi rigid connection. in this study threedimensional models of conventional pallet racking system were prepared using the finiteelement program ansys and finite element analysis carried out on conventional pallet rackswith the 18 types of column sections developed a...

In this paper, we investigate more relations between the symmetric residuated lattices $L$ with their corresponding intuitionistic fuzzy residuated lattice $tilde{L}$. It is shown that some algebraic structures of $L$ such as Heyting algebra, Glivenko residuated lattice and strict residuated lattice are preserved for $tilde{L}$. Examples are given for those structures that do not remain the sam...
