Background:  A significant increase in cesarean section in worldwide is known as one of the health system problems. The WHO has estimated that cesarean section in recent years has been 10% in all countries. Despite the increasing popularity of cesarean section, the literature lacks insights about factors affecting the selection of this delivery method. In this vein, this study investigates the ...

the developing turbulent flow in an open channel is a complex three-dimensional flow influenced by the secondary currents and free surface effects and is, therefore, not amenable to analytical solution. this paper aims to study the impact of three key hydraulic parameters (relative roughness, the froude number and the reynolds number) on the establishment length using computational fluid dynami...

The volatile components of the leaves of four species and five varieties of the section Bicornes of Heterotropa were examined by gas chromatography and gas chromatograph-mass spectrometry. The analytical results showed that the species of the section contain phenylpropanes, terpenes, and a paraffin as main components. The components have been used to construct phylogenetic trees of the section ...

This project is a combined analytical and experimental activity to study warping deformation in shafts of non-circular cross section subjected to torsion. This is a supplemental activity for the junior level Mechanics of Materials course. The students see the warping in square sections and their pronounced effects in ductile materials such as aluminum when the stresses exceed the material yield...

Analytical tools in business management are understood as a combination of information technologies and quantitative methods used to assist stakeholders to make better decisions. The contemporary business environment is dramatically changing by the massive accumulation of data. Now, as never before, the use of analytical tools must be expanded to take advantage of this growing digital universe....

frps (fiber reinforced polymer) possess many favorable characteristics suitable and applicable for construction industry when compared with steel reinforcement. there are new ideas to use frps as longitudinal or transverse reinforcement for new concrete elements particularly for bridge decks or beams. although high tensile strength of frp is main characteristic for applications at both areas, i...
