Abstract This study aimed to explore the anti-bacterial and anti-fungal activities of extracts from different parts of plants in the Zingiberaceae family. The inhibitory rate, minimum inhibitory concentration (MIC), and minimum bactericidal concentration (MBC) of leaf and stem, and root and rhizome extracts from Alpinia katsumadai Hayata, Alpinia oxyphylla Miq × Alpinia henryi K. Schumann, Alpinia oblongifolia Hayata, Alpinia nigra (Gaertn.) Burtt, Amomum villosum Lour, Alpinia zerumbet (Pers.) Burtt. et Smith and Alpinia oxyphylla Miq were determined using the fungus cake method and double dilution method. The seven Zingiberaceae plants exhibited characteristic antibacterial activities against pathogenic bacteria and fungi. At a… More >

Abstract Biobased polymers have been gaining the attention of society and industry because of concerns about the depletion of fossil fuels and growing environmental problems. Cellulose fi bers are one of the most promising biopolymers to be explored as a component of composite materials with emergent properties for new applications. Bacterial Cellulose (BC), a special kind of cellulose produced by microorganisms, is endowed with unique properties. In this context, this perspective offers an overview about the properties of BC that would enable it to become a commodity. This includes an appraisal of the current BC market, as compared with other available… More >

Abstract Due to their high crystallinity and aspect ratio, bacterial cellulose nanowhiskers (BCNW) represent an appealing choice for the development of fully biobased nanocomposite materials with high barrier performance. However, their strong tendency to self-associate, together with their highly hydrophilic character, has restricted the production of nanocomposites containing cellulose nanowhiskers by industrial processing techniques such as melt compounding. Th is article presents an overview of the latest published results carried out within our group and also in other relevant literature, which have led to the development of an effi cient strategy for the incorporation of highly dispersed BCNW by melt compounding… More >

Abstract The Internet of Things (IoT) technologies has gained significant interest in the design of smart grids (SGs). The increasing amount of distributed generations, maturity of existing grid infrastructures, and demand network transformation have received maximum attention. An essential energy storing model mostly the electrical energy stored methods are developing as the diagnoses for its procedure was becoming further compelling. The dynamic electrical energy stored model using Electric Vehicles (EVs) is comparatively standard because of its excellent electrical property and flexibility however the chance of damage to its battery was there in event of overcharging or deep discharging and its mass… More >

Abstract Land salinization is a major form of land degradation, which is not conducive to the growth and quality of fruits and vegetables. Plant salt tolerance can be enhanced by arbuscular mycorrhizal fungi (AMF) or plant growth-promoting rhizobacteria (PGPR). This study examined the effects of inoculation with PGPR singly or in combination with AMF, on the growth and quality of tomato fruits under low saline conditions. Tomatoes were cultivated in a greenhouse with sterilized soil, inoculated with PGPR, AMF, or co-inoculated with PGPR and AMF, and NaCl solution (1%) was added to the soil. The results indicated that AMF + PGPR… More >

Abstract Silver nanoparticles (Ag NPs) are an effective antibacterial agent, but their application in food packaging is limited due to their easy agglomeration and oxidation. In this study, antibacterial microcapsules were fabricated using Ginkgo biloba essential oil (GBEO) as core material and chitosan and type B gelatin biopolymer as capsule materials. These antibacterial microcapsules were then modified with green-synthesized Ag NPs, blended into the biopolymer polylactic acid (PLA), and finally formed as films. Physicochemical properties and antibacterial activity against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) were evaluated. Results showed that the prepared antibacterial PLA films exhibited excellent antibacterial… More > Graphic Abstract

Abstract Renewable energy sources (RES) such as wind turbines (WT) and solar cells have attracted the attention of power system operators and users alike, thanks to their lack of environmental pollution, independence of fossil fuels, and meager marginal costs. With the introduction of RES, challenges have faced the unit commitment (UC) problem as a traditional power system optimization problem aiming to minimize total costs by optimally determining units’ inputs and outputs, and specifying the optimal generation of each unit. The output power of RES such as WT and solar cells depends on natural factors such as wind speed and solar irradiation… More >

Abstract Novel branched silicone methacrylate was developed. The mechanical and biological properties of the resin system were investigated to select the formula proportion with the best overall performance. The novel silicone-containing monomers were combined with an incremental sequence of glass filler concentrations in commonly used Bis-GMA/TEGDMA (50/50, wt./wt.) dental resin systems. Physicochemical properties, surface properties, antibacterial adhesion effect, anti-biofilm effect, protein adsorption, and cytotoxicity were evaluated. The results showed that BSMs did not affect the double bond conversion of dental resin, but could reduce volumetric shrinkage (p < 0.05). The BSM containing resins can resist protein and bacteria adhesion (S. Mutans)… More >

Abstract Most bacteria assemble a ring-like macromolecular machinery scaffolded by the essential cytoskeletal protein FtsZ for cell division. Studies have broadly explored how FtsZ could polymerize at the correct place and time. Recently, the FtsZ-ring was found to exhibit dynamic treadmilling along the circumference of the division site, driven by GTP hydrolysis. This apparently directional motion of FtsZ seems to drive the movement of septal cell wall synthesis enzymes and to play an important role in modulating cell envelope constriction and septum morphogenesis. However, the relationship between FtsZ’s treadmilling dynamics and cell wall synthesis varies in different bacteria. More importantly, the… More >

Abstract Histopathology is the investigation of tissues to identify the symptom of abnormality. The histopathological procedure comprises gathering samples of cells/tissues, setting them on the microscopic slides, and staining them. The investigation of the histopathological image is a problematic and laborious process that necessitates the expert’s knowledge. At the same time, deep learning (DL) techniques are able to derive features, extract data, and learn advanced abstract data representation. With this view, this paper presents an ensemble of handcrafted with deep learning enabled histopathological image classification (EHCDL-HIC) model. The proposed EHCDL-HIC technique initially performs Weiner filtering based noise removal technique. Once the… More >
