In this study, a general volumetric and sound velocity method was used to analyze the effects of sodium benzoate (SB) on the structure of essential amino acids (L-lysine, L-arginine). Densities and sound velocities of ...

The collection of soil samples is labored and time consuming as well as the determination of heavy metal concentrations in laboratory was expensive. To these attempts, artificial intelligence techniques (AI) such as adaptive ...

Hydroxyapatite, (HAp), Ca10(PO4)6(OH)2, is a naturally occurring material found in the inorganic component of human bone and enamel. The constituent elements of HAp are primarily calcium and phosphorous, with a stoichiometric ...

In this thesis, we have extended He’s homotopy perturbation method for obtaining the approximate analytical solution of second order generalized strongly nonlinear Duffing equation with varying coefficients in presence ...

Environmental flow requirement certifies natural condition prominence of a river. Due to terrestrial location, rivers in Bangladesh have faces precise high flow in wet season and low flow in dry season. Since the current ...

An integrated drainage path is an important component for tropical countries. If heavy rainfall occurred with lacking of drainage path, water logging is the consequence of the surroundings. Three southwestern coastal ...

Lattice theory is an important part of mathematics . Ideal lattice and n-ideal of a lattice have played many roles in development of lattice theory. Historically, lattice theory started with Boolean distributive lattices: ...

In the present study, the Advanced Research WRF (ARW) model v3.8.1 has been used to simulate the rainfall for the month of May 2015 all over Bangladesh. The initial and boundary conditions are drawn from the global operational ...

The present research work is focused on Yttrium (Y) doped Ni-Zn ferrites. The ferrite samples of the composition Ni0.25Zn0.75YxFe2-xO4 [where x= 0.00, 0.02, 0.04, 0.06 and 0.08] were synthesized by conventional solid ...

Shrimp industries are though important in respect of foreign earnings they are producing huge amount of wastewater that contain large quantities of biodegradable organic wastes and disposed directly to the environment ...
