Development of secondary bacterial and fungal infections are well-known complications of viral pneumonia. In this pandemic situation, tracking the recent developments and disease epidemiology is of utmost importance to develop a better strategy to combat the disease. In the present study, a literature review was carried out to understand the status of fungal co-infections in Covid-19 patients. The study observed a high incidence of aspergillosis and candidiasis fungal infections in several European and American countries. While, in India, there was a surge in mucormycosis cases among Covid-19 patients. The use of vaccines and strict adherence to medical guidelines seems to be the only strategy to defeat Covid-19 pandemic and secondary infections.</p> 2022-02-15T00:00:00+0330 Copyright (c) 2022 Advanced Journal of Science and Engineering https://sciengpub.com/adv-j-sci-eng/article/view/advjse22031002 Structural and Electronic Analysis of Tautomerism in 5,6-Difluor-2,4(1H,3H)-Pyrimidindion 2022-02-03T22:11:15+0330 Hasan Zandi h.zandi@qom.ac.ir <p>Density functional theory (DFT) calculations were performed to analyze the structural and electronic features of tautomers of 5,6-difluor-2,4(1H,3H)-pyrimidindion, as a possible compound for pharmaceutical applications. To this aim, possible structures of tautomers were obtained by performing optimization calculations and their electronic features were investigated. The results indicated that the tautomerism process could change the original features of 5,6-difluor-2,4(1H,3H)-pyrimidindion, in which different impacts of such changes could be observed for the list of tautomeric structures. Finally, further pharmaceutical uses of 5,6-difluor-2,4(1H,3H)-pyrimidindion compound should be in accordance with the structural and electronic features of the tautomeric formations.</p> 2022-02-15T00:00:00+0330 Copyright (c) 2022 Advanced Journal of Science and Engineering https://sciengpub.com/adv-j-sci-eng/article/view/advjse22031007 Surface Modified Benzoylated Okra (Abelmoschus esculentus) Bast Fiber Reinforced Polypropylene Composites 2021-06-30T15:27:16+0430 Haydar U Zaman haydarzaman07@gmail.com Ruhul A Khan dr.ruhulkhan7@gmail.com <p>Nonwoven unidirectional Okra fiber (OF)-reinforced polypropylene (PP) based composites were manufactured by a hot press machine and their interfacial, physicomechanical features, thermal degradation, and weather test were examined. This paper reports the effect of OF content, alkaline treatment of fiber, as well as inclusion of benzoylation as coupling agent on the features of PP/OF composites, was studied. The outcomes indicated that the OFs performed as reinforcing fillers, developing the mechanical features (e.g., tensile strength, tensile modulus, impact strength, and hardness) of the composites. PP/OF composites with benzoylation after alkaline pretreatment exhibited better mechanical features than alkali treatment and untreated composites. The interfacial feature was examined by scanning electron microscopy (SEM) and it was found that the interfacial interaction between PP and OF was increased due to the treatment of the fibers, which validates the obtained mechanical features of the composite. Moisture absorption experiments have shown that benzoylation treatment of OF composites shows lower water absorption than both alkali-treated and untreated composites. Thermal degradation and weather tests of the composites were also investigated.</p> 2022-02-15T00:00:00+0330 Copyright (c) 2022 Advanced Journal of Science and Engineering https://sciengpub.com/adv-j-sci-eng/article/view/advjse22031018 Density Functional Theory Investigation of Lead Adsorption by a Graphene Layer 2022-02-06T22:01:18+0330 Parastoo Bayat p-bayat@mail.com Mohammad Yousefi myousefi50@hotmail.com <p>According to the importance of heavy metal pollutants removal from environment, this work was performed to adsorb lead (Pb) metal by means of a model of graphene (Gr) layer. To approach this goal, density functional theory (DFT) calculations were performed to obtain the optimized 3D molecular structures besides evaluating the electronic features. The adsorption of Pb atomic substance was investigated in this work, and the results indicated its appropriate adsorption by the Gr layer. Moreover, examining the electronic molecular orbital features also indicated that the Gr model could work as a sensor for detection of the existence of Pb in addition to the capability of its adsorption and removal. As a consequence, the investigated model system of this work could be proposed for working in dual functions of detection and removal for Pb from the environment.</p> 2022-02-15T00:00:00+0330 Copyright (c) 2022 Advanced Journal of Science and Engineering https://sciengpub.com/adv-j-sci-eng/article/view/advjse22031023 Preparation and Characterization of Polypropylene/Organo-Muscovite Clay Nanocomposites by Melt Extrusion 2021-07-10T08:54:44+0430 Haydar U Zaman haydarzaman07@gmail.com Ruhul A Khan xxx@dd.cc <p>In this research work, polypropylene (PP)/organo-muscovite clay (OM) nanocomposites with different filler contents were manufactured using melt compounding technique in a twin-screw co-rotating extruder tracked by hot press method. Two compatibilizers such as maleated polypropylene and hexamethylenediamine modified maleated polypropylene copolymer were included in all nanocomposites containing 10 wt%. Mechanical properties have been observed to be influenced by OM nanoparticles as well as copolymer content. For tensile properties, the most observed were related to the sample with 5 wt% OM. The hexamethylenediamine modified maleated polypropylene copolymer system conferred superior tensile features than maleated polypropylene copolymer system and the PP/OM case. This outcome was confirmed from TEM and SEM micrographs. Evidently, the compatibilizers were operative to support the OM delamination. The hexamethylenediamine modified maleated polypropylene system had a partial exfoliation of PP/OM nanocomposites compared to the maleated polypropylene system. The inclusion of compatibilizers with OM has improved all tensile and thermal properties as well as the rheological behavior of nanocomposites, enhancing the strong interfacial interactions by compatibilizers.</p> 2022-02-15T00:00:00+0330 Copyright (c) 2022 Advanced Journal of Science and Engineering https://sciengpub.com/adv-j-sci-eng/article/view/advjse22031035 Simultaneous Compensation of Active and Reactive Power in the Power System Using Grid-Connected Electric Vehicles 2021-11-13T21:54:13+0330 Ebadollah Amouzad Mahdiraji ebad.amouzad@gmail.com Mojtaba Sedghi Amiri mojtabasedgheamiri@yahoo.com <p>Network-connected electric vehicles, in addition to reducing pollution, have capabilities to assist power systems. One of the most important of these capabilities is responding to the needs of the network to produce active and reactive capabilities. In this paper, considering the network constraints, technical considerations and market prices, a theoretical framework for allocating the capacity of these vehicles is presented. For this purpose, a goal function with the approach of minimizing the costs paid by the distribution system operator or DSO to the manufacturer of each of the active and reactive capabilities is proposed. Due to the fact that the problem in question is in the form of an optimization problem, new innovative solutions have been added to the algorithm to solve it from the optimization algorithm and to prevent the algorithm from getting stuck in local optimizations. In this proposed format, vehicles compete with generators to generate active and reactive power. The efficiency of the proposed method is evaluated on a low voltage network feeder with 134 subscribers and in the presence of active and reactive power generation sources, and the amount of production and costs paid for each manufacturer are determined.</p> 2022-02-15T00:00:00+0330 Copyright (c) 2022 Advanced Journal of Science and Engineering https://sciengpub.com/adv-j-sci-eng/article/view/advjse22031049 FEM Analysis and Designing a Dynamic Sensor Made of Ionic-Polymer-Metal Composites 2022-02-24T01:06:12+0330 Amin Nasrollah amin_nasrollah@mecheng.iust.ac.ir Mohammad Hossein Nikkhou mohammadhosseinnikkhou@gmail.com Hamid Soleimanimehr soleimanimehr@srbiau.ac.ir <p>With science and technology fast developing, demand for smart materials has been on the rise, raising expectations for the better performance of such materials Ionic polymer metal composite (IPMC) as a new smart material with low voltage and large deformation has gained increasing attention, nowadays, thanks to its properties. This study analyzes the performance of IPMC as a sensor in two dimensional mode using finite element method for one and two Hz frequencies. The present work focuses on polymer composites in which an electroactive layer coated with platinum on two sides and studies their electromechanical and piezoelectric effects. It also examines the effects of alternating current on the number of signals received from Ionic membrane. The outcomes demonstrate that vibrations of 1.5 &amp; 2 Hz frequency produce respectively voltages of 2.4 &amp; 2.5 millivolts.</p> 2022-02-15T00:00:00+0330 Copyright (c) 2022 Advanced Journal of Science and Engineering https://sciengpub.com/adv-j-sci-eng/article/view/advjse22031055 Design and Fabrication of Magnetic Field System for Improving EDM Process 2022-02-25T10:47:40+0330 Seyed Sina Zabihi sinazabihi@srbiau.ac.ir Hamid Soleimanimehr soleimanimehr@srbiau.ac.ir Shahram Etemadi Haghighi setemadi@srbiau.ac.ir Adel Maghsoudpour admp100@yahoo.com <p>Electric discharge machining is one of the non-traditional machining methods. In this process, many of the limitations of traditional machining methods have been removed, which is why the use of EDM in the manufacture of industrial parts and molds has greatly increased today. However, electric discharge machining has low efficiency and high energy consumption, and the quality of the machined surface in this method is low. For this reason, researchers have always been trying to find a way to increase the efficiency and quality of the surface. One of the most effective methods is the application of external magnetic field in electric discharge machining. Applying a magnetic field around the machining range in EDM leads to increased machining efficiency, reduced tool corrosion, increased chipping rate, reduced surface roughness and improved surface integrity. Previous research has shown positive results from magnetic field applications, but so far, no mention has been made of how to design a magnetic field application system. Undoubtedly, building an efficient system to apply the magnetic field in EDM is a challenges of using this method. In this article, using previous research, experiences gained and scientific foundations of a method to build this system will be presented.</p> 2022-02-15T00:00:00+0330 Copyright (c) 2022 Advanced Journal of Science and Engineering https://sciengpub.com/adv-j-sci-eng/article/view/advjse22031001 Advanced Journal of Science and Engineering: An Open-Access and Peer-Reviewed International Journal 2022-03-11T21:48:18+0330 Kun Harismah kun.harismah@ums.ac.id <p><strong>Advanced Journal of Science and Engineering</strong> (<strong>Adv.

First-principles methods are used to characterize the interface of these hybrid systems. Previous work has shown that the sensing capabilities of pristine BNNT are limited by long-ranged interactions. In this study, the surfaces of pristine and functionalized BNNTs are investigated. The surfaces of the functionalized BNNTs give new properties to the tubes, which may enhance their sensing capabilities, while retaining their stability and chemical inertness. The calculated elastic properties exhibit anisotropic mechanical properties that surpass graphene in the armchair direction. For the calculations 2D and 3D, Au6, Au10, Au12, Au14 and Au16 clusters were selected. Their properties were analyzed in a free-standing configuration and on a substrate of h-BN.</p> 2022-02-15T00:00:00+0330 Copyright (c) 2022 Advanced Journal of Science and Engineering
