Energy-exergy and environ-economic (4E) analysis of heat storage-based single-slope solar stills integrated with solar air heater.

The energy-exergy and environ-economic (4E) analysis was conducted on a solar still with and without a hybrid thermal energy storage system (TESS) and a solar air heater. The proposed solar still was modified by integrating a rectangular aluminium box filled with paraffin wax and black gravel as the TESS and coupled with a solar air heater. Paraffin wax was selected due to its widespread availability and proven effectiveness in accelerating desalination, improving process uniformity, and maintaining optimal temperature levels.

Exploring the efficacy of drought tolerant, IAA-producing plant growth-promoting rhizobacteria for sustainable agriculture.

The growing human population and abiotic stresses pose significant threats to food security, with PGPR favorable as biofertilizers for plant growth and stress relief. In one study, soil samples from both cultivated and uncultivated plants in various cities were used to isolate rhizobacterial populations. Using 50 soil samples from both cultivated and uncultivated plants, isolated rhizobacterial populations were screened for various biochemical changes, PGP activities and morphological characteristics.

Outcomes in Adenoid Cystic Carcinoma: A 14-Year Analysis.

Background Adenoid cystic carcinoma (ACC) is a rare malignancy characterized by slow progression, local recurrence, and distant metastases. This study aims to evaluate the demographic patterns, clinical presentations, outcomes, and survival trends of patients with ACC. Methods A retrospective analysis of 14 patients diagnosed with ACC from 2010 to 2024 at a tertiary cancer center in the United Arab Emirates was conducted.

A Comparative Study of Propofol-Dexmedetomidine Versus Propofol-Ketamine for the Anesthetic Management of Patients During Endoscopic Retrograde Cholangiopancreatography.

Introduction Endoscopic retrograde cholangiopancreatography (ERCP) requires effective sedation for patient comfort and procedural success. This study compares propofol-dexmedetomidine (group DP) and propofol-ketamine (group KP) for anesthetic management during ERCP. Methods This randomized, double-blinded study enrolled 50 patients (aged 18-60 years) scheduled for ERCP at Dr.
