Optimization of Bis-anthraquinones Production from Endophytic Fungi Diaporthe sp. GNBP-10
...Show More Authors

Bis-anthraquinones with a unique molecular backbone, (+)-2,2’-epicytoskyrin A (epi) and (+)-1,1′-bislunatin (bis), was produced by endophytic fungi Diaporthe sp GNBP-10 associated with Gambir plant (Uncaria gambier). Epi and bis possess robust antimicrobial activity toward various pathogens. This study focus on knowing the optimum condition of epi and bis production from Diaporthe sp GNBP-10. A series of culture media with various nutrient compositions was investigated in epi and bis production. The content of epi and bis was determined by measuring the area under the curve from TLC-densitometric (scanner) experiment. The linear regression analysis was then applied to obtain the results. The optimized epi and bis production was observed in liquid media 3 containing potato starch and dextrose with the amount of epi produced is 0.484mg while bis content is 0.163mg. The presence of carbohydrates, whether simple sugar or carbohydrate complex, plays an essential role in the bis-anthraquinones production from Diaphorthe sp culture. The presence of minerals and excessive protein sources did not significantly affect bis-anthraquinones production. 

Keywords: bis-anthraquinone, Diaporthe sp, culture media, regression, TLC scanner

Unifying The Evaluation Criteria Of Many Objectives Optimization Using Fuzzy Delphi Method
...Show More Authors

Many objective optimizations (MaOO) algorithms that intends to solve problems with many objectives (MaOP) (i.e., the problem with more than three objectives) are widely used in various areas such as industrial manufacturing, transportation, sustainability, and even in the medical sector.  Various approaches of MaOO algorithms are available and employed to handle different MaOP cases. In contrast, the performance of the MaOO algorithms assesses based on the balance between the convergence and diversity of the non-dominated solutions measured using different evaluation criteria of the quality performance indicators. Although many evaluation criteria are available, yet most of the evaluation and benchmarking of the MaOO with state-of-art a

Process Optimization Study of Pb(II) Removal by Bulk Liquid Membrane (BLM)
...Show More Authors

   Box-Wilson experimental design method was employed to optimized lead ions removal efficiency by bulk liquid membrane (BLM) method. The optimization procedure was primarily based on four impartial relevant parameters: pH of feed phase (4-6), pH of stripping phase (9-11), carrier concentration TBP (5-10) %, and initial metal concentration (60-120 ppm). maximum recovery efficiency of lead ions is 83.852% was virtually done following thirty one-of-a-kind experimental runs, as exact through 24-Central Composite Design (CCD). The best values for the aforementioned four parameters, corresponding to the most restoration efficiency were: 5, 10, 7.5% (v/v), and 90 mg/l, respectively. The obtained experimental data had been

Path Planning of an autonomous Mobile Robot using Swarm Based Optimization Techniques
...Show More Authors

This paper presents a meta-heuristic swarm based optimization technique for solving robot path planning. The natural activities of actual ants inspire which named Ant Colony Optimization. (ACO) has been proposed in this work to find the shortest and safest path for a mobile robot in different static environments with different complexities. A nonzero size for the mobile robot has been considered in the project by taking a tolerance around the obstacle to account for the actual size of the mobile robot. A new concept was added to standard Ant Colony Optimization (ACO) for further modifications. Simulations results, which carried out using MATLAB 2015(a) environment, prove that the suggested algorithm outperforms the standard version of AC

Formulation and optimization of clotrimazole nail lacquer as transungual drug delivery system
...Show More Authors

Clotrimazole nail lacquer was created using this research, which also included the incorporation of two different kinds of polymers. (Eudragit RL 100 and ethyl cellulose) in various concentrations, as well as castor oil as a plasticizer, salicylic acid as a keratolytic agent, and N-acetylcysteine as a penetration enhancer. The objective was to optimize the selection of polymers and their concentrations to enhance release efficacy based on in vitro permeability experiments, while also ensuring favorable film characteristics, such as flexibility, gloss, adhesive qualities, drying time, non-volatile content, viscosity, and water resistance. Formulation F3 was selected as the superior formula considering several parameters, including excellent

Computational Optimization of the Radial and Spiral Distortion Aberration Coefficients of Magnetic Deflector
...Show More Authors

Abstract:The optimum design of the magnetic deflector with the lowest values of the radial and spiral distortion aberration coefficients was computed. The optimized calculations were made using three models, Glaser bell-shaped, Grivet-lenz and exponential models. By using the optimum axial field distribution, the pole pieces shape which gave rise to those field distributions was found by using the reconstruction method. The calculations show that the results of the three models coincide at the lower values of the excitation parameter. In general the Glaser- bell shaped model gives the optimum results at the whole range of the excitation parameter under investigation.The negative values of the spiral distortion aberration coefficient appears
