A field study was conducted in a semi-arid climate to assess the effect of nitrogen and phosphorus on timely sown bed planted wheat under varying irrigation levels. The soil sandy loam, having 0.36% organic carbon pH 8.2. It low available N (132 kg/ha), medium P (11.6 kg/ha) rich K (325 kg/ha). experiment consisted sixteen treatment combinations four levels (Two, three, five irrigations) main p...

‎‎In the category of Mordell curves (E_D:y^2=x^3+D) with nontrivial torsion groups we find curves of the generic rank two as quadratic twists of (E_1), ‎and of the generic rank at least two and at least three as cubic twists of (E_1). ‎Previous work‎, ‎in the category of Mordell curves with trivial torsion groups‎, ‎has found infinitely many elliptic curves with ...

We sought to explore the therapeutic potential of xylitol irrigations in treating chronic rhinosinusitis (CRS). Saline irrigation, which has been shown to be beneficial for patients with rhinosinusitis, served as an accepted standard treatment for comparison. We conducted a prospective, randomized, crossover study to compare the therapeutic value of saline versus xylitol irrigations in patients...
