We discuss the recent paper by Inan and Ugurlu [Inan I.E., Ugurlu Y., Exp-function method for the exact solutions of fifth order KdV equation and modified Burgers equation, Appl. Math. Comp. 217 (2010) 1294 – 1299]. We demonstrate that all exact solutions of fifth order KdV equation and modified Burgers equation by Inan and Ugurlu are trivial solutions that are reduced to constants. Moreover, w...

The investigation on the reproductive life of Indian Mackerel, Rastrelliger kanagurta (Cuvier 1817) in Uttara Kannada coast for a period 13 months was performed from Jan 2018 to 2019. A total 1299 fishes were dissected entire and their biological parameters investigated. Of these fishes, 734 female, 435 male 130 indeterminate. Throughout year fishery present with copiousness pre-monsoon post-mo...

We consider the radial structure of radiatively inefficient hydrodynamic accretion flows around black holes. We show that low-viscosity flows consist of two zones: an outer convection-dominated zone and an inner advection-dominated zone. The transition between these two zones occurs at ∼ 50 Schwarzschild radii. Subject headings: accretion, accretion disks — black hole physics — convection Depar...

Isotopic abundance ratios Mg:Mg:Mg are derived for 20 stars from highresolution spectra of the MgH A-X 0-0 band at 5140Å. With the exception of the weak G-band giant HR 1299, the stars are dwarfs that sample the metallicity range -1.8 < [Fe/H] <0.0. The abundance of Mg and Mg relative to the dominant isotope Mg decreases with decreasing [Fe/H] in fair accord with predictions from a recent model...

Results: A total of 1299 women delivered singleton live births at full term during the stipulated time period. Mean maternal age was 23.28±3.39 years, 53% were primi-gravida and 48.8% were high risk pregnancy. Low birth weight (LBW) was prevalent amongst 19.3% new born. Among the independent significant factors associated with the LBW, primigravida, hypertensive mothers, non cephalic presentati...
