This study focused the optimization of radiofrequency (RF) assisted heat pump (HP) drying Ganoderma lucidum. Response surface methodology (RSM) optimized levels three independent variables as air temperature, velocity, and RF power to obtain maximum value Polysaccharide content minimum time. Box–Behnken design (BBD) was employed evaluate effects velocity on time in The optimum predicted conditi...

Obtaining the required surface finish and geometric accuracy together with attaining high production rate is a challenge in finishing of inner surfaces steel pipes bushes. One promising techniques for metal parts electrochemical machining. In this paper, roughness dimensional inaccuracy CK45 bush were controlled electrochemically. For this, special machine was constructed. The effect electric p...

Pectic-Oligosaccharides (POS) have a growing potential in food and feed industries. To satisfy the demand of worldwide markets from POS and avoid the shortcomings of currently applied methodologies encountered in their preparation, the present study highlights a novel robust approach for POS biosynthesis. In the current approach, Aspergillus sp.section Flavi strain EGY1 DSM 101520 was grown on ...

A fucoidan discovered in the plant Fucus vesiculosus, which lowered molecular weight of fucoidan, was ideal for its application pharmaceutical and food sectors. The aim to study impact ultrasound process parameters on weight, structure, antioxidant activity fucoidan. For optimization sonochemical such as temperature, sonication time, power (intensity), Box–Behnken design (BBD) through response ...

The hydrothermal method as the eco-friendly environmental was used in this study to prepare a high efficient nanocomposite adsorbent based on biochar (BC) derived from Eriobotrya japonica leaves and magnesium oxide nanoparticles (MgO NPs). prepared materials were characterized using FTIR, BET, SEM-EDX, TEM, XRD. adsorption of tartrazine (TZ) BC, MgO NPs, BC@MgO NPs better described by kinetic p...

In modern power systems, transformers are considered vital components that can ensure the grid’s continuous operation. this regard, studying breakdown in transformer becomes necessary, especially its insulating system. Hence, study, Box–Behnken design (BBD) was used to introduce a prediction model of voltage (VBD) for oil presence different barrier effects point/plane gap arrangement with alter...

A number of laser parameters are often regulated to enhance ablation efficiency during laser surgery. As one of clinical treatments, laser removal of benign prostate hyperplasia has been well accepted by surgical urologists. However, due to complex interactions of the surgical parameters, the procedure is still lengthy and dependent upon the surgeon’s skill and experience. The aim of the curren...

The present research studies the performance of Converter Sludge (CL)as a nano-activator of persulfate (PS) in Permeable Reactive Barrier (PRB) as an in-situ technology for leachate treatment.In batch experiments, the acidic conditions (pH = 3) have been the most suitable for removal operations, where COD and NH3 removal efficiencies are 69.15% and 60.96%, respectively. The Box–Behnken design (...
