Process Optimization of Biodiesel Production from Gmelina Arborea Seed Oil Using Brine as Catalyst
Authors : C. Victor Nwakwuribe,P. Chibundo Nwadinobi,O. Igri Uket,I. Kingsley Mejeh,

https://doi.org/10.29294/IJASE.11.1.2024.3754-3767

In this study, the optimal process conditions for the production of biodiesel from Gmelina arborea seed oil were investigated using the transesterification method. The impacts of process parameters such as catalyst concentration, reaction time, reaction temperature, methanol/sample ratio, and agitation speed were investigated separately and, in a matrix, to determine synergistic relationships....

Investigating the Phonon Spectral Properties of Nickel and Palladium-based Heusler Alloys
Authors : Preeti Sharma,Rajni Kant,Purvee Bhardwaj,

https://doi.org/10.29294/IJASE.11.1.2024.3768-3787

This study delves into the phonon spectra, martensitic transformations, and magnetic properties of Ni₂MnGa, Ni₂MnAl, and Pd₂MnZ (Z = Ga, Ge, As) alloys. Focusing on Ni₂MnGa, we observe a martensitic transformation at 202 K, closely related to a pre-transformation phase at 260 K, reflecting the compound's sensitivity to temperature and external influences. Investigations into supercell...

Synthesis, Characterization and Biological Evaluation of Schiff Base Ligand and their Fe (III) Complexes
Authors : D.T. D.T. Sakhare,

https://doi.org/10.29294/IJASE.11.1.2024.3788-3797

In this study, heterocyclic Schiff base ligands derived from 2-amino-4,6-dihydroxypyrimidine and 2-hydroxy-1-naphthaldehyde (L1) were synthesized. These ligands were used in the synthesis of Fe(III) complexes. The synthesized compounds were characterized using FT-IR, 1H-NMR and UV-Vis techniques for the ligands, and TLC, molar conductivity and magnetic susceptibility measurements for the...

Development of Database for Drying Parameters of Some Fruit Crops in South-East Nigeria
Authors : Edeani Nkiruka Justina,Nwankwo Godson,G.O Mbah,

https://doi.org/10.29294/IJASE.11.1.2024.3798-3815

This work is on developing a database for drying parameters of some Nigerian fruit crops: banana, guava, and plantain. Experimental data was collected and stored in a database. A relational database for drying parameters of three foodstuffs was developed using Microsoft Structured Query Language Server(MS SQL) 2012 database management system and Microsoft Visual Studio.Net 2013 framework was...

Metamaterials: A Comprehensive Review of Design and Applications
Authors : Ashok S. Lakamanahalli,Mallikarjun G. Hudedmani,G.M. Shweta,Priya Hoskeri,Shridhar N. Mathad,

https://doi.org/10.29294/IJASE.11.1.2024.3816-3835

Every material in its various forms of existence possesses specific property and applications in various fields. In the similar way metamaterials are those hypothetical and expert to possess a specific property and applicable to various domains. These materials are engineered artificially with specific structures designed to exhibit the properties which are not available in naturally occurring...

Authors : Maryam Ghalebiyan,Mansour Kazemi Moghadam,R. Khalilzadeh,

https://doi.org/10.29294/IJASE.11.1.2024.3836-3854

In this study, the laboratory data of an experimental paper on separating the food process by ultrafiltration was used and entered as the input experimental data for the MLP multi-layer neural network modeling. The operating parameters were pressure, time, frequency, and flux. According to the created results and the regression coefficient R2 and MSE values evaluation, the Levenberg-Marquart...

Bioethanol Production from Citrus Peel Waste in the absence of D-Limonene
Authors : Renuka Subramaniam,Jaffeer Ashraf Akbarshieak,Harish Kalaiselvan,Selvamani Selambayiram,Kalaivanan Muthusamy,

https://doi.org/10.29294/IJASE.11.1.2024.3855-3861

Citrus peel wastes were studied for bioethanol production using the H2SO4 pretreatment method and the fermentation of Saccharomyces cerevisiae. This study investigates the potential of acidic pre-treatment for 3 h at 100 °C to remove D-Limonene. The results obtained from FT-IR analysis confirmed that D-limonene was significantly decreased from 0.21% to below 0.01%. The density of the...

On Prognosis of Transport of Salt Solution in a Xylem
Authors : E.L. Pankratov,

https://doi.org/10.29294/IJASE.11.1.2024.3862-3866

One way to get nutrients from trees and grasses is to transport them through the roots. As plants use their roots, nutrients pass through the xylem. There has been interest in estimating the above nutrient amount to select the required increase in plant body weight. For estimation, we consider a model of the vertical rise of a saline solution in the xylem. We analyze the kinematic changes of the...
