The Red Sea remains a largely under-explored basin, with the Northern Egyptian Red Sea requiring further investigation due to limited borehole data, sparse case studies, and poor seismic quality. A petroleum system, regional structural cross-section, and geological block diagrams integrating onshore fieldwork from Gebel Duwi and offshore subsurface geology were utilized to assess the hydrocarbon potential of the Northern Egyptian Red Sea (NERS). The findings highlight that pre- and syn-rift organic-rich source units in the NERS could generate oil and gas, similar to the capped reservoirs of the Southern Gulf of Suez.

Aim: To evaluate the role of preoperative neutrophils to lymphocytes ratio (NLR) as a predictor for the response to BCG in patients with non-muscle invasive bladder cancer (NMIBC).

Materials: Nighty six patients with NMIBC were prospectively included in our study. Our study population was classified into two groups, based on pre-operative (NLR) either ⩽ or > 3.

The current study introduces the first micellar-enhanced spectrofluorimetric approach for the estimation of the commonly abused CNS antitussive, dextromethorphan (DXM) in its syrup and biological fluids. A micellar solution of sodium dodecyl sulfate (SDS) containing DXM showed high native fluorescence emission at 305 nm following excitation at 224 nm. Using SDS as a micellar system resulted in about a 2.

Article Synopsis
  • Steel pipeline systems, which transport about 75% of the world's oil and gas, require protective coatings to prevent corrosion and erosion.
  • This research introduces a multi-layered composite coating made from carbon fiber-reinforced thermoplastic polymer (CFRTP) as an alternative to traditional epoxy-based coatings.
  • The study evaluates the physical, mechanical, and corrosion-resistant properties of the coated carbon steel samples, revealing that the unidirectional (UD) composite offers the highest flexural strength, while the biaxial composite exhibits the best corrosion resistance.

Hypertension is the predominant risk factor for cardiovascular diseases and mortality. This study presents the first method for the simultaneous analysis of the co-administered antihypertensive drugs, Carvedilol (CAR) and Telmisartan (TEL) using a fast, highly sensitive, environmentally friendly, and cost-effective second derivative synchronous spectrofluorimetric approach. The fluorescence of CAR and TEL was quantified at 243 nm and 274.
