Comparing surgical techniques: ThuLEP and transurethral BPEP for prostate over 80 grams. Intraoperative and postoperative results. A prospective randomized trial.

Background And Purpose: Though TURP remains the primary treatment for BPH, advancements in energy and technology have introduced innovative transurethral surgical options. In this study, we assessed and compared the effectiveness and safety of using thulium laser and bipolar for endoscopic enucleation of prostate exceeding 80 g.

Patients And Methods: Between January 2022 and July 2023, this study enrolled patients with LUTS due to BPH and a prostate size of ≥80 g.

High early strength concrete incorporating waste derived nanomaterials for sustainable construction.

This paper contributes to the expanding knowledge base on nanomaterial-enhanced cementitious composites, offering valuable insights for developing high-performance, sustainable concrete solutions. The study assessed the effects of three different types of nanomaterials-nano clay (NC), nano silica (NS), and nano cellulose (NCel)-on the compressive strength of high-early-strength concrete (HESC) through both experimental studies and a 2 factorial design. Incorporating nanomaterials into the HESC matrix led to a decrease in workability, with NCel demonstrating the least impact on this property across all studied replacement percentages.

Evaluation of polyester high-tenacity fabric and carbon nanotube reinforcements for improving flexural response in concrete beams.

This research scrutinized the effectiveness of utilizing polyester high tenacity fabrics to enhance the functionality of concrete panels. Two distinct woven fabrics with comparable strength resistance were fabricated and assessed. Concrete beams were compared in their original form and those reinforced with woven fabrics, along with beams reinforced with carbon nanotubes (CNTs) (B, BC2, BC4, BS1, and BS2).

Achieving sustainable performance: synergistic effects of nano-silica and recycled expanded polystyrene in lightweight structural concrete.

Lightweight concrete, particularly polystyrene concrete, has been extensively utilized in civil engineering for decades. The incorporation of waste expanded polystyrene (EPS) as a filler material in the production of lightweight concrete presents significant advantages from a circular economy perspective. Prior research indicates that increasing the proportion of lightweight aggregates, such as EPS, typically results in reductions in strength and bulk density.

Seismic analysis of Islamic Egyptian minarets through 3D scanning and dynamic simulation.

Recently, Egypt had seismic activity. These seismic events have affected the stability of minarets, especially historical ones. Weight is one of the minaret's main stability factors.
