A Byzantine Metaphysics of Artefacts? The Case of Michael of Ephesus’ Commentary on Aristotle’s Metaphysics
Authors: Papandreou Marilù
Published: August 2022

The ontology of artefacts in Byzantine philosophy is still a terra incognita. One way of mapping this unexplored territory is to delve into Michael of Ephesus’ commentary on Aristotle’s Metaphysics. Written around 1100, this commentary provides a detailed interpretation of the most important source for Aristotle’s ontological account of artefacts. By highlighting Michael’s main metaphysical tenets and his interpretation of key-passages of the Aristotelian work, this study aims to reconstruct Michael’s ontology of artefacts and present it as one instance, which is perhaps exemplary, of the Byzantine ontology of artefacts. In particular, the study shows that this commentary holds a definite position on the nature of artefacts, according to which they are neither substances nor hylomorphic compounds. Indeed, artefacts lack a form altogether and their forms exist only in thought. As a result, Michael’s commentary provides an ontological interpretation of artefacts as accidental beings, i.e., as matter which acquires a mere property as opposed to a substantial form. While such an interpretation shows originality when compared to the Aristotelian text, it also indicates adherence to the reading established by Alexander of Aphrodisias, despite important departures concerning the status of natural forms.
Au Nanoparticles Coated ZnO Film for Chemical Sensing by PIERS Coupled to SERS
Authors: Barbillon Grégory
Published: August 2022

In this work, we present a study on the sensing of chemical molecules with Au nanoparticles coated ZnO film by employing the photo-induced enhanced Raman scattering (PIERS) coupled to the surface-enhanced Raman scattering (SERS). Moreover, the interest of coupling the PIERS to classical SERS (electromagnetic contribution) is to achieve a high sensitivity of detection. In our work, we employed the thiophenol molecule for its quality of adsorption on metals and its small size. For this thiophenol detection, we found a limit concentration of 100 pM, an adsorption capacity (KAds) of 3.2 × 106 M−1 and an analytical enhancement factor of 1.9 × 1010.
Generation of Elliptic-Symmetry Radially Polarized Optical Beam by Circle-Cassinian Optical Coordinate Transformation
Authors: Wei Huan , Fang Hui
Published: August 2022

Recently, optical coordinate transformation has garnered considerable research interest for manipulating structured light in emerging optical communication applications. Herein, we propose a circle-Cassinian optical coordinate transformation based on polarization invariance to generate an elliptical-symmetry radially polarized (ESRP) optical beam. Accordingly, we designed three isotropic phase plates for placement in the 4f optical system. The numerical simulations demonstrated accurate generation of the ESRP beam with specified intensity, including an overall intensity adjustment applied in the input plane. Therefore, the proposed method can aid in designing vector light fields, and the ESRP beam can be applied to optical tweezers and surface plasmonic-field generation.

The consumption of functional beverages is rapidly increasing. The improvement in the functional properties of whey after the application of ultrasound is due to the release of bioactive peptides that have antioxidant properties, among others. Bioactive peptides with antioxidant activity have also been found in oats, stimulating the study of whey beverages formulated with oats to obtain functional products. The aim of this study was to determine the influence of ultrasound (24 kHz) at 20 °C for 15 min at 23 W and 154 W on the quality and functional properties of whey–oat (50:50 v/v) beverages and compare it with pasteurization at 65 °C for 30 min (LTLT). Non-significant effect (p > 0.05) of ultrasound intensity (23 W and 154 W) was observed on the physicochemical characteristics and the proximal composition of the whey–oat beverages. The sonicated beverages showed a greater tendency to green and yellow color (p < 0.05), higher fat content (p < 0.05), and less ash and carbohydrates (p < 0.05) than the pasteurized beverage. The antioxidant activity of the mM Trolox equivalent/mL of the sonicated beverages was higher (p < 0.05) (4.24 and 4.27 for 23 W and 54 W, respectively) compared to that of the pasteurized beverage (4.12). It is concluded that ultrasound is superior to pasteurization in improving the antioxidant activity of whey–oat beverages without having a detrimental impact on the proximal composition and physicochemical quality. Future studies should evaluate more functional parameters and determine the shelf life of sonicated whey–oat beverages.

Published: August 2022

Ni-rich layered cathode materials for lithium-ion batteries have received widespread attention due to their large capacity and low cost; however, the structural stability of the material needs to be improved. Herein, F-doped and undoped cathode materials prepared with an advanced co-precipitation method were used to measure the effect of F doping on the material. Compared to the undoped sample, the F-doped cathode materials exhibited an improved rate performance, because the porous structure of F-doped cathode materials is favorable for the infiltration of the electrolyte and the material, and the F-doped cathode material has a larger (003) crystal plane and a smaller Li+ migration barrier energy. This simple F-doping treatment strategy provides a promising way to improve the performance of Ni-rich layered cathode materials for lithium-ion batteries.
Limited Intervention and Moral Kindergartens
Authors: Lim Daniel
Published: August 2022

Recently, William Hasker and Cheryl Chen have argued that James Sterba’s argument for the non-existence of God based on the existence of horrendous evil consequences fails. Hasker, among other things, contends that eliminating horrendous evil consequences will result in a moral kindergarten. It is unclear, however, whether the elimination of horrendous evil consequences will result in a moral kindergarten. Moreover, if Hasker is right, then it may be that most people in the actual world live in a moral kindergarten. Chen argues that eliminating horrendous evil consequences may lead to a morally worse world. While Chen is ultimately right about this, it is not fatal to the basic intuition at the heart of Sterba’s argument.

The consequences of a stroke are manifested by a number of unfavorable functional disorders of the motor apparatus, which leads to a significant deterioration in the patients’ quality of life. In this regard, the prevention of the development of disability and the reduction of the severity of the patients’ condition should come to the fore when creating rehabilitation programs to ensure maximum recovery of functional activity, as well as mental, professional and social adaptation of patients. Material and methods: 120 patients after acute cerebrovascular accident with movement disorders in the form of hemiparesis with increased muscle tone of spasticity type in the late recovery period. At the control points (after treatment, 3 and 6 months after treatment), indicators of patients’ daily activity (self-care and mobility) were assessed according to the Barthel index and criteria for patients’ functional independence were evaluated in accordance with the FIM scale. All patients were divided into 3 groups comparable in terms of clinical and functional characteristics: group 1 (40 patients), who, in addition to the standard treatment complex, were prescribed massage with the pulsed low-frequency electrostatic field from the Khivamat device and broadband modulation currents, group 2 (40 patients), who, against the background of standard therapy and medical rehabilitation, were prescribed physiotherapy methods from the Alpha LED Oxy Light — Spa™ device, and group 3–40 patients who received standard drug therapy and medical rehabilitation (exercise therapy, medical massage, mechanotherapy). Results. The data obtained indicate the advantage of including the pulsed low-frequency electrostatic field and broadband modulation currents in the standard rehabilitation complex in patients with acute cerebrovascular accident, which is confirmed by the indicators of patients’ daily activity (self-care and mobility) according to the Barthel index and the criteria for patients’ functional independence in accordance with the FIM scale. Conclusion. The developed personalized medical rehabilitation complexes, including the pulsed low-frequency electrostatic field and broadband modulation currents, contribute to a significant improvement in daily activity and an increase in functional independence in patients after acute cerebrovascular accident at a late stage of medical rehabilitation.

Simulation of an Industrial Wastewater Treatment Plant by Up-flow Anaerobic Fixed Bed Bioreactor Based on an Artificial Neural Network
Authors: Verijkazemi Kobra , Jalilzadeh Yengejeh Reza
Published: August 2022

Given the variable nature of industrial wastewaters, the appropriate operation of an industrial wastewater treatment plant (WWTP) is a prerequisite for keeping process stability at ideal conditions. In this respect, an artificial neural network (ANN) can be a powerful device for the prediction of treatment performance. This study assessed some qualitative parameters of industrial wastewater (Amol Industrial Estate) during a one-year operating period. The wastewater treatment process consisted of an equalization tank, up-flow anaerobic fixed bed (UAFB) bioreactor, activated sludge tank, sedimentation tank, and chlorination basin. The ANN was utilized to estimate the system efficiency of the UAFB process. The outcomes demonstrated an extraordinary arrangement between the real and simulated data (R2>0.8). This model supplied a proper device for forecasting the implementation of WWTPs. Continuous checking elements could be used for the simulation of wastewater specifications.

The removal of formaldehyde as a toxic substance from aqueous solutions is of particular importance. In this research, a sequencing batch rotating-bed bioreactor (SBRB) was used on a laboratory scale for biodegradation of formaldehyde from synthetic wastewater. The reactor was made of plexiglas with a cylindrical shape. Kaldnes media were placed in a rotating cylindrical basket in the reactor. The effects of formaldehyde concentration (500–1500 mg/L), hydraulic retention time (HRT) (8, 15, 24 hours), and injection of hydrogen peroxide (0.1-0.5 mM) on the performance of the reactor were investigated. The results showed that in the SBRB, at an HRT of 24 hours and an inlet formaldehyde concentration of 1000 mg/L, the removal efficiencies of formaldehyde and chemical oxygen demand (COD) were 99.2% and 92%, respectively, while without rotating the bed, the removal efficiency of formaldehyde and COD was found to be 95% and 83%, respectively. By adding hydrogen peroxide at a concentration of 0.3 mM and operation of the SBRB with an HRT of 8 hours and an inlet formaldehyde concentration of 1000 mg/L, an improvement in the removal efficiency of formaldehyde and COD (4% and 22%, respectively) was observed. Accordingly, SBRB stimulation with hydrogen peroxide could be considered as a high-performance process for the removal of formaldehyde and corresponding COD at a short HRT.

This parasite is able to cause a hydatid cyst in humans, which causes various human and financial losses annually. Objective: This study focused on determining the polymorphism of antigen B (AgB) of E. granulosus in the human and animal samples of Alborz province. Materials and Methods: In this study, 50 samples of the hydatid cyst fluid (HCF), 10 human samples, and 40 sheep samples were collected, then the DNA was extracted from the samples. During the polymerase chain reaction (PCR) process, the corresponding fragment was replicated in the AgB gene. Subsequently, PCR-single-strand conformation polymorphism (SSCP) was performed to investigate genetic diversity. Results: All 50 isolates used in this study showed the AgB in 350 bp after conducting PCR. In addition, all isolates demonstrated similar band patterns after the PCR-SSCP assay. Conclusion: In 50 isolates, one banding pattern was observed after PCR-SSCP, while no polymorphism was detected in any of the isolates.

Non-Hodgkin’s lymphoma includes 60% of lymphoma cases in children and adolescents. Burkitt’s lymphoma and diffuse large B-cell lymphoma (DLBCL) patients usually have intra-abdominal tumors. Non-Hodgkin’s lymphoma (NHL) may present as retroperitoneal fibrosis (RF). In the present paper, a 7-year-old boy was reported who was hospitalized in our hospital because of stomachache, vomiting, and weight loss. In the patient’s history, it was found that 3 weeks ago, the patient complained of flank pain and suspected kidney stones, but urethroscopy revealed that he did not have kidney stones. After admission to our hospital, upon the examination of the abdomen, we noticed a palpable mass in the patient’s epigastric region. Diagnostic laparoscopy was performed, and a large number of hard lesions similar to fibrosis were detected in the mesogastric region, the first part of the small intestine, the head of the pancreas, and the liver. Finally, DLBCL was diagnosed in this patient.

The need for electrical energy continues to increase along with population growth. it is very important to encourage the use of new and renewable energy to support electricity needs. One of them is the use of wind energy. Wind can be used to drive a turbine coupled to a generator. Permanent magnet synchronous generator (PMSG) is a type of generator that is often used in the utilization of wind energy. The main component of PMSG consists of three components, namely the stator, rotor and permanent magnet. The interaction between the components causes a ripple or often referred to as the cogging phenomenon. Cogging is what makes PMSG not work perfectly. This study discusses the effect of teeth width on decreasing the cogging torque value in PMSG by making two designs. The design variations used are teeth width 7 mm and 4 mm, Carpenter type of iron core: Silicon steel, Permanent magnet synchronous generator 18 slot 16 pole (PMSG 18s16p). The result of decreasing the value of cogging torque obtained is 0.012676 Nm with 4 mm teeth width. For numerical analysis using the finite element method (FEM).
