Luteinising Hormone-to-follicle-stimulating Hormone Ratio for Predicting Unexplained Infertility in Patients with Hypovitaminosis D

BACKGROUND: Hypovitaminosis D critically influences reproductive hormones in women of reproductive age. The luteinising hormone (LH)/follicle-stimulating hormone (FSH) ratio predicts poor ovulatory response. OBJECTIVE: To evaluate the correlation between the LH/FSH ratio and hypo...

Numerical simulation of fully developed laminar flow and heat transfer in a circular pipe

Purpose This work involves the computational analysis of two-dimensional heat transfer through convection and laminar flow of a fluid. The application was conducted on a circular pipe with fully developed laminar flow, taking into consideration boundary conditions such as the wal...

Comparative Fatigue Crack Growth and Fractographic Investigation of Composite‐Patch–Repaired Al 2024‐T3 and Al 7075‐T6 Aerospace Alloys

ABSTRACT This study compares fatigue crack propagation and fracture mechanisms in Al 2024‐T3 and Al 7075‐T6 aerospace alloys repaired with bonded carbon/epoxy composite patches. Single‐edge notched tension specimens were tested under identical constant‐amplitude cyclic loading, a...
