In this paper, load-carrying capacity in steel shear wall (SSW) was estimated using artificial neural networks (ANNs). The SSW parameters including load-carrying capacity (as ANN’s target), plate thickness, thickness of stiffener, diagonal stiffener distance, horizontal stiffener distance and gravity load (as ANN’s inputs) are used in this paper to train the ANNs. 144 samples data of each of th...

in the present research work, the kinetics of sunflower oil transesterification reaction in the presence of ba-sr/zsm-5 nanocatalyst which prepared using incipient wetness impregnation method was investigated. the 10wt.%ba-sr/zsm-5 (sr/ba=3/2) nanocatalyst was calcined at 600 °c for 6 h with a heating rate of 3 ºc/min. the experimental conditions were the methanol/oil 9/1molar ratio, reaction t...

In this study, the adsorption of Reactive blue 19 onto pomegranate residual-based activated carbon PRAC was investigated in aqueous solution. The activated carbon prepared by phosphoric acid activation under air condition. PRAC was characterized for its surface chemistry by point of zero charge measurements, Scanning Electron Microscopy and nitrogen adsorption at 77 K. The effect of operational...

This paper concerns the reconstruction of the absorption and scattering parameters in a time-dependent linear transport equation from knowledge of angularly averaged measurements performed at the boundary of a domain of interest. Such measurement settings find applications in medical and geophysical imaging. We show that the absorption coefficient and the spatial component of the scattering coe...

The article presents an outline of the requirements concerning the planning of preclinical and clinical studies, necessary for the legal approval of a medicinal product. It describes the clinical research plan of innovative and generic pharmaceutical products, taking into account the specific situations in which the assessment of biological equivalence of a generic product is not possible based...

We argue that in the high energy QCD a true black disk wave function consists not only of many gluons but also from many quarks. This corresponds to necessity of nonvacuum reggeon loops in formation of a black disk. The result comes from decomposition of the black disk S-matrix in characters on group manifold. Usually black disk defined as some dense state, which absorbs any projectile. In this...

The kinetics of iodination of the phenol and substituted phenols using pyridiniumiodochloride in methanol has been studied under varying conditions. The rates show first orderkinetics each in pyridinium iodochloride and phenols. The rates of reactions are measured atdifferent temperature and activation parameters for all phenols computed. Hammett plot is foundto be valid and the corrletion betw...

Carbon activated powdered was prepared from activated carbon derived from olive stone. Then byusing the surface methodology, many parameters such as pH, furnace temperature (T), acid ratio,time of activation that affect on the qualities prepared activated carbon produced and its efficiencywere investigated. In addition, the adsorption of Congo Red onto the activated olive stone carbonactive was...
