Second-Order Slip Effect on MHD Flow and Radiative Heat Transfer through Porous Medium due to an Exponentially Stretching Sheet
Authors: Kaushik Preeti , Mishra Upendra 
Published: August 2022

The magnetohydrodynamic (MHD) boundary layer flow and radiative heat transfer with second-order slip condition are investigated in this paper. The fluid flow is considered towards an exponentially stretching sheet. The effect of magnetic field and thermal conductivity are taken into account. The obtained nonlinear mathematical expression of the flow are transformed into ordinary differential equations by similarity transformation. The coupled higher order nonlinear ordinary differential equations are solved numerically. The solution for velocity and temperature profile against the first and second-order slip parameters are analyzed. Significant changes are observed in skin friction coefficient and Local Nusselt number due to the magnetic parameter. The characteristics of the flow are discussed through graphs for different pertinent parameters. The results designate that the Local Nusselt number reduces with the increased value of magnetic parameter but opposite behavior is observed for the skin friction coefficient. The rate of heat transfer decreases with higher value of Prandtl number and enhances for Radiation parameter.
HIGHLIGHTS

Phenomenon of an exponentially stretching sheet with thermal conductivity also incorporate in fluid flow
Behavior of magnetic parameter (M) and Radiation parameter (R) are analyzed
Highly nonlinear mathematical equations are solved numerically

Enhancing SDS-PAGE Detection of Dilute Extracellular Polystyrene Degrading Enzymes Expressed by Bacillus megaterium Strain via Centrifugal Freeze Concentration Method
Authors: Tan Kian Meng , Fauzi Noor Akhmazillah Mohd , Kassim Angzzas Sari Mohd , Rehan Aisyah Mohd 
Published: August 2022

This study aims to enhance the sodium dodecyl sulphate polyacrylamide gel electrophoresis (SDS-PAGE) detection and visualization of extracellular polystyrene degrading enzyme expressed by Bacillus megaterium as a result of utilizing polystyrene as a sole carbon source. Dilute polystyrene degrading enzyme expressed in the culture supernatant could not be directly visualized from SDS-PAGE stained with colloidal Coomassie blue stain as it falls below its sensitivity or detection limit level. To overcome this problem, the crude enzyme extract was concentrated via the centrifugal freeze concentration method (cryoconcentration). The extracellular enzyme profiles were determined by SDS-PAGE. The SDS-PAGE analysis of the concentrated enzyme extract revealed 6 visible protein bands ranging in size from 10 to 60 kDa. Three distinct protein bands at approximately 20, 45 and 60 kDa were observed to be highly expressed in the culture supernatant. Polystyrene degrading enzyme extracted from the culture supernatant was closely related to several polymer degrading enzymes which suggest that the extracted enzyme from Bacillus megaterium also belongs to the hydrolase’s enzyme family. GC-MS analysis of the extracted samples significantly contains benzene derivatives due to the breaking down of the long-chain aromatic hydrocarbon polymer. Hydroxylation of the aromatic ring formed phenolic substrate took place which suggests being facilitated by intracellular enzyme hydroxylases. Hence, the biodegradation of polystyrene by Bacillus megaterium was believed to incorporate both intracellular and extracellular enzymes.
HIGHLIGHTS

Bacillus megaterium strain was first reported to contribute to polystyrene biodegradation
Polystyrene degrading enzyme expressed by Bacillus megaterium was detected through SDS-PAGE
Cryoconcentration enhanced SDS-PAGE protein detection
The protein bands were most distinct visualized at approximately 20, 45 and 60 kDa by SDS-PAGE
GC-MS analysis detected benzene derivatives which confirmed enzymatic degradation activity

Authors: Entuni Gibson , Nori Hollena , Edward Rebicca , Jaafar Ahmad Kamil bin Mohammad 
Published: August 2022

Morphological and genetic characterization of MCBC1, PBC230, KKM22 and KKM4 cocoa clones derived from staminode and immature zygotic embryo culture were compared with those conventionally grafted. Somatic embryogenesis culture successfully produced true-to-type progenies of elite cocoa clones of MCBC1, PBC230, KKM22 and KKM4 (from staminode culture). Phenotype variations (p < 0.05) were observed only in KKM4 clone from immature zygotic embryo culture which exhibited lower quantities in the fresh pod weight, number of flat beans per pod, seed length, seed width and individual seed weight. The genetic stability of the cultured clones was tested using fragment analysis with 12 SSR primers to validate these results. Eleven of these SSR primers detected mutations only in the allelic profiles of KKM4 clone from immature zygotic embryo. These results validated those variations in KKM4 clones of immature zygotic embryo culture were due to interactions between genotypic and explant types. Unfortunately, these variations were negative attributes to cocoa productivity. Thus, it is suggested that successful production of true-to-type KKM4 cocoa clone should consider other means of propagation including modification of the culture conditions.
HIGHLIGHTS

It is crucial to evaluate and confirm the quality of the immature zygotic and staminode regenerated cocoa plant before using the culture technique for commercial production
The quality can be detected in both phenotype and genotype by comparing the regenerated cocoa plant with those regenerated from the conventional asexual propagation method of grafting
Phenotype and genotype differences were only observed in KKM4 clone regenerated from immature zygotic embryo culture and thus validated that this clone exhibited variation
KKM4 clone from immature zygotic embryo culture which has lower quantities in the fresh pod weight, number of flat beans per pod, seed length, seed width and individual seed weight confirmed the negative effect of using immature zygotic embryo explant for KKM4 clone propagation. It is suggested to modify the culture technique

Simulation and Comparative Study of Resonant Tunneling Diode
Authors: Shah Yashvi , Kapoor Isha , Singhvi Purva , Birua Babita , Parekh Rutu 
Published: August 2022

This paper studies and investigates the effect of physical and electrical parameters on double, triple and six barrier resonant tunneling diodes (RTD). The materials used for quantum well and barriers are Gallium arsenide (GaAs) and Aluminium gallium arsenide (AlGaAs), respectively. The parameters that were reasoned and studied include conduction band, current density, transmission coefficient and resonance energy. The above parameters were studied by changing bias voltage, temperature, barrier width and doping concentration. From the simulations performed it is observed that for double barrier RTD the peak current density is observed at 0.2 V and the valley current density is observed at 0.3 V, whereas for a triple barrier RTD the peak current density is observed at 0.015 V and the valley current density is observed at 0.06 V. The value of transmission coefficient for double barrier RTD decreases especially after bias applied is more than resonant bias (0.2 V). The effect of increasing bias leads to a decrease in the resonance level in the conduction band. The width of resonance energy decreases with the increase in barrier width. With increase in number of barrier the number of resonance level increases which leads to an increasing peaks in the transmission coefficient curve. The effect of increasing temperature leads to higher current and more resonance energy. With the thickening of barrier width, less transmission of electrons occurs leading to a reduced current density. When the barriers are increased the negative differential region (NDR) is achieved at low voltages.

Authors: Sereenonchai Kamonthip , Inla Chawarit , Buajarern Siriwit 
Published: August 2022

A simple microfluidic thread-based analytical device (mTAD) for determination of phosphorus content in fertilizers based on the formation of phosphomolybdenum blue (PMB) complex was proposed. The proposed mTAD was simply fabricated by stitching the 100 % cotton thread to the polyethylene (PE) mesh canvas. A color developing reagent, which are the mixture of sulfuric acid, ammonium molybdate, potassium antimony tartrate, and ascorbic acid, was firstly loaded into the middle of the thread. A sample solution was subsequently introduced into the same position to form PMB. A digital camera and image processing program were employed for evaluating color intensity of PMB. Variable parameters affecting the mTAD efficiencies were optimized i.e., solution volumes, chemical concentrations, and reaction time. The applicability of the proposed mTAD method was evaluated by analyzing fertilizer samples. The accuracy as expressed by percentages of recovery ranged between 83 and 96 %. The method was highly reproducible with the relative standard deviation (RSD) of 0.84 % (1 mgP/L), 0.92 % (3 mgP/L) and 1.04 % (10 mgP/L) for 10 replicates. The main features of the system are the used of commonly available materials, simple and rapid fabrication, small scale, reduced chemical waste, less sample consumption, and low-cost.
HIGHLIGHTS

Simple materials such as 100 % cotton thread and PE mesh canvas can be used for fabricating µTAD
The proposed µTAD method was fast analysis and good sensitivity (as low as nmol P level within 6 minutes) by using small amount of reagent and sample solutions
The method was successfully determining the phosphorus content in fertilizers

Published: August 2022

Objectives This study sought to evaluate the incidence and the mechanism of post-procedural cardiac biomarker (CB) rise following device implantation. Background A fully bioresorbable Absorb scaffold, compared with everolimus-eluting metallic stents (EES), might be associated with a higher incidence of periprocedural myocardial injury. Methods Prospective nonrandomized comparative study enrolled 52 patients with stable myocardial ischemia with diffuse/ long LAD lesion for either an everolimus-eluting bioresorbable vascular (BVS) scaffold (22 patients) or an EES (30 patients), 3 types of CB (creatine kinase (CK), creatine kinase-myocardial band (CK-MB), and troponin) were obtained before and after procedure. Per protocol, periprocedural myocardial infarction (PMI) was deﬁned as CK rise >2 the upper limit of normal with CK-MB rise. Results Incidence of side branch occlusion (SBO) and any anatomic complications assessed by angiography was similar between the 2 treatment arms (SBO: Absorb: 4.5% vs. Xience: 6.7%, p=1; One PMI with acute instent thrombosis occurred in EES group. Dissection occurred in only 1 patient in BVS arm after stent implantation; this event was not associated with elevated cardiac biomarkers. One patient had PMI in BVS arm with no angiographic complications to explain it.
