A comparative petrophysical evaluation of the Abu Roash, Bahariya, and Kharita reservoirs using well-logging data, East El-Fayoum, Egypt.

The exploration and development of hydrocarbon resources in the Western Desert require more continuous activities. The Silah is a newly discovered field in this region. Therefore, this study emphasizes the application of petrophysical evaluation to sandstone and carbonate reservoirs from the late and early Cretaceous.

Comprehensive insights into phosphorus solubility and organic matter's impact on black phosphate leaching.

The current study introduces groundbreaking insights into how organic matter (OM) of the black phosphate (RB-Ph) uniquely influences phosphorus (P) solubility during acetic acid (AA) leaching, expanding our understanding in this crucial area. To highlight such role, the OM of the RB-Ph was treated separately by different procedures including calcination at 550 ℃/4 h (CB-Ph), 30% hydrogen peroxide (HB-Ph) and intensive grinding to nano-sizes (NB-Ph). The mineralogical, chemical and morphological characteristics of phosphatic and non-phosphatic components of these phosphatic materials were carefully examined pre- and post-treatment via different techniques.

Sigmoid Colon Perforation, Pelvic Collection, and Hydronephrosis Caused by an Ingested Chicken Wishbone.

This case report presents an unusual and challenging case of an 82-year-old female patient who presented with constipation and abdominal pain and was diagnosed with bowel perforation and hydronephrosis caused by an ingested chicken wishbone. This patient was treated with emergency laparotomy and bowel sigmoid resection. She made a good recovery and was discharged home.
