Review ArticleOpen accessIn the abstractOverview of the Most Popular Currently Used Murine Models of AtherosclerosisAnastasia Vladimirovna Poznyak, Victoria Alexandrovna Khotina, Alexandra Alexandrovna Melnichenko et al.Atherosclerosis is a widespread and serious problem. Every year it causes a huge number of deaths and morbidity. Many aspects of this disease remain not fully understood, which indicates the need to search for the most representative model of atherosclerosis in animal and cell culture models. Animal models resembling the pathophysiology in humans are needed to study the immunometabolic mechanisms … …OnLine Journal of Biological Sciences, Vol. 24, Issue 2 · 4 Jan 2024 · 4,669 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Activated Carbon from Eggshell Membranes Prepared Using Sodium Acetate and Zinc Metal ActivationSumrit Mopoung, Kanjana JitchaijaroenkulThe eggshell membranes of ducks and hens were carbonized or activated with 4 wt% sodium acetate or zinc at 400-600°C. The carbonized or activated products were characterized by SEM-EDS, TEM, FTIR and XRD. It was found that the suitable activation temperature for eggshell membranes is 500°C with 30.03-35.26% yield. The activation performance of CH3COONa for eggshell membrane activated carbon production … …American Journal of Applied Sciences, Vol. 14, Issue 8 · 2 Aug 2017 · 8,525 accessesView PDFCite
Research ArticleOpen accessIn the abstractGreen Synthesis of Silver Nanoparticles using Mediterranean Cypress (Cupressus sempervirens) Leaf ExtractAlireza Ebrahiminezhad, Saeed Taghizadeh, Younes GhasemiSilver nanoparticles (AgNPs) retained vast applications in science and technology. Due to the vast application of these particles in various disciplines, there is an interest for synthesis of AgNPs in an environmentally friendly and economic manner. For the first time we were used Mediterranean cypress (Cupressus sempervirens) leaf aqueous extract for biosynthesis of AgNPs. Prepared particles were in various shapes … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 1 · 5 Feb 2017 · 9,392 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of the Characteristics of Thulium Doped Alumina Nanoparticles for Applications in Silica-Based FibersNur Atiqa Bt Rahmat, Hairul Azhar Abd Rashid, H.Y. Wong, Mukter ZamanIt is reported that during the fabrication of doping RE ions into the silica preform, the distribution of particles is inhomogeneous and becomes uneven throughout the fiber which lead to unwanted spectroscopic characteristics. It is assumed that by using thulium doped with alumina, the problem with the inhomogeneity of the particles inside the fiber can be solved. With the incorporation … …American Journal of Applied Sciences, Vol. 14, Issue 1 · 26 Jan 2017 · 7,411 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Method for the Non-Destructive Assessment of Strength Degradation and Re-Use Potential of Weathered Float Glass From Facades: A Proof of Concept StudyFred Veer, Mauro Overend, Irene Sofokleous, Chris NoteboomLack of knowledge about the properties of weathered (used) glass is currently a major barrier to glass reuse. This results in probably unnecessary recycling or down-cycling of architectural glass at the end of life. Avoiding this creates a significant opportunity to reduce resource depletion and decarbonize the built environment. This can be done by developing an optical non-destructive test method … …International Journal of Structural Glass and Advanced Materials Research, Vol. 7, Issue 1 · 19 Oct 2023 · 9,292 accessesView PDFCite
Review ArticleOpen accessIn the abstractSubfractions of Low-Density-Lipoprotein: Which is the Most Atherogenic?Anastasia Vladimirovna Poznyak, Vasily Nikolaevich Sukhorukov, Mikhail Аleksandrovich Popov et al.Atherosclerosis is a widespread disease of the arteries, which manifests itself in the narrowing of the lumen of the vessel due to the formation of plaque on its walls. Despite an impressive history of study, atherosclerosis still leaves room for researchers. This is realized due to the complexity of pathogenesis, in which important roles are assigned to a variety of … …OnLine Journal of Biological Sciences, Vol. 23, Issue 4 · 3 Sep 2023 · 4,697 accessesView PDFCite
Research ArticleOpen accessIn the abstractAir Quality Interpretation of Four Geographically Distinct Hot Spot States of India-An Appraisal Using Aerosol Optical Depth and Particulate MatterJacob Joshua, Aishwarya Sathyachandran, Chenicherry House SujathaThe application of Moderate Resolution Imaging Spectroradiometer-Aerosol Optical Depth (MODIS-AOD) for Air Quality (AQ) assessment has contributed significantly by making use of a spatiotemporal relationship between ground-level particulate matter and aerosol optical density at both city and state levels. Traditional ground-based site-specific particulate matter monitoring method has found a profound gap in their spatial coverage. Such challenging situations prevail over … …American Journal of Environmental Sciences, Vol. 18, Issue 6 · 8 Feb 2023 · 5,883 accessesView PDFCite
Research ArticleOpen accessIn the abstractCFD-PBE Modelling and Simulation of Enzymatic Hydrolysis of Cellulose in a Stirred TankNorazaliza Mohd Jamil, Qi WangRenewable energy or biofuel from lignocellulosic biomass is an alternative way to replace the depleting fossil fuels. The production cost can be reduced by increasing the concentration of biomass particles. However, lignocellulosic biomass is a suspension of natural fibres and processing at high solid concentration is a challenging task because it will affect the mixing quality between the enzyme and … …Journal of Mathematics and Statistics, Vol. 12, Issue 4 · 25 Oct 2016 · 7,999 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Study of Particle Emissions from a Modern 5 kW Pellet StoveIgor V. Dyakov, Benjamin Bergmans, Svend Bram et al.This work is dedicated to the determination of the particle emission from a commercially available bottom feed 5 kW pellet stove. Two-stage dilution was applied to provide the operational stability and conditioning of the sample. The analysis of particle emission was performed by means of the Electrical Low Pressure Impactor with 14 stages, able to separate particles from 0.006 to … …Energy Research Journal, Vol. 7, Issue 2 · 25 Oct 2016 · 6,998 accessesView PDFCite
Research ArticleOpen accessIn the abstractFractal Dimension for the Characterization of Asphalt Mixture PropertiesGiovanni LeonardiIn the design of asphalt mixtures for paved roads, the shape of solid elements has a great importance. In asphalt concrete, the shape of aggregate particles influences the resistance, durability, stiffness, fatigue response and the required binder content of the mixture. Fractal geometry is more suitable to describe the irregularity of the shape of aggregate particles.
