Response of Juvenile Clarias gariepinus to Varying Dietary Levels of Ionotropic Gelated Chitosan Nanoparticles Synthesized from Wasted Crab Shells

Autor: S. I. Umanah, S. K. Umoren, I. U. Udo

Publikováno v: Asian Journal of Fisheries and Aquatic Research. :32-41

Background: Crab shells lie wasted globally after the extraction of the edible soft tissues. Chitosan nanoparticles (CNPs) derived from these shells have the potentials to revolutionized aquaculture. Aims: Evaluated the effects of CNPs on water quali

Effects of Replacing Soybean Meal with Fermented Bambara Groundnut Meal (Vigna subterranea) Meal in the Diet of Clarias gariepinus Fingerlings

Autor: O. C. Ozor, I. U. Udo

Publikováno v: Asian Journal of Fisheries and Aquatic Research. :25-33

Background: Efforts to reduce fish feed cost have been geared towards fishmeal replacement with cheap ingredients. However, the price of soybean which is a supplementary protein source in fish diet is also soaring due to impact of covid-19 pandemic c

Perturbation Approach in the Dynamic Buckling of a Model Structure with a Cubic-quintic Nonlinearity Subjected to an Explicitly Time Dependent Slowly Varying Load

Autor: A. M. Ette, I. U. Udo-Akpan, A. C. Osuji, M. F. Noah, J. U. Chukwuchekwa

Publikováno v: Journal of Advances in Mathematics and Computer Science. :1-19

This investigation is concerned with analytically determining the dynamic buckling load of an imperfect cubic-quintic nonlinear elastic model structure struck by an explicitly time-dependent but slowly varying load that is continuously decreasing in

Asymptotic Analysis of the Static and Dynamic Buckling of a Column with Cubic - Quintic Nonlinearity Stressed by a Step Load

Autor: I. U. Udo–Akpan, W. I. Osuji, J. U. Chukwuchekwa, A. M. Ette

Publikováno v: Journal of Advances in Mathematics and Computer Science. :1-35

In this paper, the static and dynamic buckling loads of a viscously damped imperfect finite column lying on an elastic foundation with cubic – quintic nonlinearity but trapped by a step load (in the dynamic case) is investigated analytically. The m
