dual systems of steel moment frame and reinforced concrete shear wall have combined the advantages of steel frames and reinforced concrete shear wall. these walls have increased the lateral stiffness of steel frames and have reduced seismic demands on steel frames thus providing opportunities to use such system. in this research intermediate dual system of steel moment frame was chosen with int...

Background: Previous studies reported that neonatal and maternal complications as well as duration of labor could be diminished through labor management. Therefore, we aimed to evaluate the effect of intramuscular (IM) administration of atropine and hyoscine combination on labor progress and maternal and neonatal outcomes in primigravid women admitted to Taleghani Hospital of Arak, Iran. Metho...

Because of the current situation where stability research filled-slope reinforced by a frame with prestressed anchor-plates lags behind actual engineering application, based on ultimate balance theory, calculation formulas factor under four arc slip surface filled-slopes are derived using improved Bishop method; corresponding search method most dangerous is given and pullout force improved. Bas...

in this paper, we establish some new results in ultra bessel sequences and ultra bessel sequences of subspaces. also, we investigate ultra bessel sequences in direct sums of hilbert spaces.specially, we show that {( fi, gi)}∞ i=1 is a an ultra bessel sequencefor hilbert space h ⊕ k if and only if { fi}∞ i=1 and {gi}∞ i=1 are ultrabessel sequences for hilbert spaces h and k, respectively.

Frenet-Serret and Bishop rigid-body motions have many potential applications in robotics, graphics and computer aided design. In order to study these motions new characterisations in terms of their velocity twists are derived. This is extended to general motions based on any moving frame to a space curve. Further it is shown that any such general moving frame motion is the product of a Frenet-S...

in this paper we study two important concepts, i.e. the direct andthe inverse limit of hyperstructures associated with fuzzy sets of type 2, andshow that the direct and the inverse limit of hyperstructures associated withfuzzy sets of type 2 are also hyperstructures associated with fuzzy sets of type 2.
