Erosion Stability of Wide-Graded Quarry-Stone Material under Unidirectional Current

Financial Stability in Islamic Banking System the Capacity to React to Current World Wide Crisis

 This paper investigates the financial stability, measured by z-score technique in Islamic banking system of 20 countries from 2000 to 2010. We compare the stability of Islamic banks to the commercial banks, before and after the financial crisis. The empirical results from panel estimation show that: a) the large Islamic banks are more stable than the large commercial banks and furthermo...

Dynamic Stability of Functionally Graded Plate under In-plane Compression

Functionally graded materials have gained considerable attention in the high-temperature applications. A study of parametric vibrations of functionally graded plates subjected to in-plane time-dependent forces is presented. Moderately large deflection equations taking into account a coupling of in-plane and transverse motions are used. Material properties are graded in the thickness direction o...

Buckling of Rectangular Functionally Graded Material Plates under Various Edge Conditions

In the present paper, the buckling problem of rectangular functionally graded (FG) plate with arbitrary edge supports is investigated. The present analysis is based on the classical plate theory (CPT) and large deformation is assumed for deriving stability equations. The plate is subjected to bi-axial compression loading. Mechanical properties of FG plate are assumed to vary continuously along ...

Investigation of Stability of Functionally Graded Material when Encountering Periodic Loading

Pulmonary problems among quarry workers of stone crushing industrial site at Umuoghara, Ebonyi State, Nigeria.

BACKGROUND Respiratory problem is one of the major health hazards in dust-exposed workers; it is a major cause of morbidity and mortality all over the world. OBJECTIVE To determine the prevalence of respiratory problems and lung function impairment among quarry workers in Ebonyi State, Nigeria. METHODS Respiratory problems and lung function were studied in 403 quarry workers aged 10-60 year...
