The Impact of Exposure of Aloe-Vera Gel Extract to Low-Level Laser Radiation as a New Therapeutics Against Streptozotocin-Induced Diabetic Rats

Abstract Background: Diabetes mellitus (DM), often just called diabetes, is a condition in which the person's body does not produce enough, or does not properly respond to insulin, or non-insulin production. Streptozotocin (STZ) is a medical agent that could use in experimental a...

Embryotoxicity and Teratogenicity of Streptozotocin-Induced Insulin-Deficient Maternal Diabetes in Sprague-Dawley Rats: A Comparative Evaluation of Insulin Glargine, Metformin, and Combined Therapy

Background & Objective: Pregestational diabetes is a leading preventable cause of congenital anomalies. We characterized Streptozotocin (STZ)-induced insulin-deficient diabetic embryopathy and compared the effects of insulin glargine, metformin, and their combination.Materials &...

Numerical and experimental study of perforated-ring inserts for water-cooled tube heat transfer

Thermal losses in absorber tubes constrain the efficiency of water-cooled photovoltaic-thermal systems. This work presents an absorber tube fitted with perforated-ring inserts, coupling high-resolution Computational Fluid Dynamics (CFD) optimization with experimental thermohydrau...

Comparative Removal of Pharmaceutically Active Compounds Using Membrane Filtration Processes

For the purpose of removing pharmaceutically active chemicals (PhACs) from wastewater, this study experimentally assesses the removal efficiency of four membrane filtration technologies: microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO) usi...

Sustainable Solar Cabinet Dryers: A Review of Design Innovations, Thermal Storage Integration, Hybrid Systems, and Techno‐Environmental Assessment

ABSTRACT Although solar cabinet dryers (SCDs) represent an alternative to open sun drying (OSD) in the preservation of agricultural products, there are still challenges for SCDs such as the solar intermittency, unequal drying, and poor thermal efficiency. This systematic review b...

Engineering context-based keywords from sentiment and domain features for enhanced review-level sentiment classification in MOOCs

Massive Open Online Courses (MOOCs) generate large volumes of learner feedback that provide valuable insights for educational improvement. However, the domain-specific language used in these reviews often limits the effectiveness of conventional sentiment analysis methods. To add...
