Between April 1982 and September 1994, 167 renal biopsies were performed in 167 children at King Khalid University Hospital, Riyadh, Saudi Arabia. The data were analysed to show a correlation between clinical presentation and histological findings. Nephrotic syndrome was the most common indication for renal biopsy, accounting for 77% of all cases. Of these, 23.3% showed minimal change lesions, 24% showed mesangial proliferative glomerulonephritis and 24% showed focal segmental glomerulosclerosis. We noted a higher incidence of congenital nephrotic syndrome and Alport's syndrome as compared with the West. On the other hand, IgA nephropathy was less common (3%), and there was a complete absence of type II membranoproliferative glomerulonephritis.

The current research focused on the synthesis of two series of pyrazole derivatives and evaluation of their insecticidal effectiveness. In the first series, seven pyrazole Schiff bases 3a-g were successfully synthesized with yields (79-95%) by condensing phenylfuran-2-carbaldehyde with substituted pyrazole rings. In the second series, eleven amino acid-pyrazole conjugates 6a-k were synthesized utilizing acetic acid, sulfuric acid, morpholine, and EDC.

We report the fabrication and characterization of a Bi(III) oxide/polypyrrole (BiO/Ppy) nanocomposite thin film optoelectronic photodetector synthesized by a simple one-pot method. The nanocomposite consists of spherical BiO nanoparticles embedded in a Ppy matrix, forming a porous structure with a high surface area. The XRD analysis reveals that the BiO nanoparticles have a poly-crystalline nature with a crystal size of 40 nm and an optical bandgap of 2.

This paper presents a novel approach to modeling and controlling a solar photovoltaic conversion system(SPCS) that operates under real-time weather conditions. The primary contribution is the introduction of an uncertain model, which has not been published before, simulating the SPCS's actual functioning. The proposed robust control strategy involves two stages: first, modifying the standard Perturb and Observe (P&O) algorithm to generate an optimal reference voltage using real-time measurements of temperature, solar irradiance, and wind speed.

Fault ruptures induced by earthquakes pose a significant threat to constructions, particularly underground structures such as pile foundations. Among various foundation types, batter pile foundations are widely used due to their ability to resist inclined forces. To gain new insights into the response of batter pile groups to fault ruptures caused by earthquakes, this study investigates the deformation and failure mechanisms of batter pile groups due to the propagation of normal and reverse fault ruptures using 3D numerical modeling.
