Abstract
Objective The aim of our study was to evaluate the effect of two different doses of lycopene, an antioxidant, on experimentally induced ovarian ischemia/reperfusion (IR) injury in rat model.
Materials and Methods Twenty-four female rats were randomly divided into four groups: sham operation (group 1), 3-hour ischemia, 3-hour reperfusion (IR) (group 2), and IR + 100 mg/kg lycopene (PO) (group 3), IR + 200 mg/kg of lycopene (group 4). The rats’ superoxide dismutase (SOD), myeloperoxidase (MPO) activities, malondialdehyde (MDA), and glutathione (GSH) levels were calculated. Ovarian tissue damage was assessed using a histopathological scoring system.
Results Serum parameter levels and histological scores showed that treatment with lycopene may be conservative approach to prevent IR injury after the ovarian detorsion procedure.The improvement with lycopene was higher at 200 mg than at 100 mg. The MPO and MDA values were significantly lower in groups 3 and 4 as compared with group 2 (p < 0.05), whereas the MPO and MDA values were lower in group 4 as compared with group 3.The SOD and GSH values were significantly higher in groups 3 and 4 as compared with group 2 (p < 0.05), whereas the SOD and GSH values were higher in group 4 as compared with group 3.Tissue damage scores were elevated in the IR group compared with the sham group, but the treatment with different lycopene doses after reperfusion improved the histopathological tissue damage scores.
Conclusion The results showed that lycopene treatment reduced ovarian IR damage. Antioxidant activity was found to increase in a dose-dependent manner. Lycopene treatment may be conservative approach for ovarian torsion patients after the detorsion procedure to prevent IR damage.

Abstract
The 2017 Unite the Right Rally in Charlottesville, Virginia represented a watershed moment for the alt-right movement in
the United States, involving a highly visible demonstration of multiple far-right hate groups. Understanding how multiple groups such as
those that “united” in the Unite the Right Rally is essential in potentially disrupting future events and curbing their ability to create
consensus. In this paper, we note that participants often engage in conflict through evaluative and authoritative stance taking. Aggression
is sometimes ignored, and other times gets escalated through interpersonal conflict. Throughout, rapport or consensus is rarely prioritized.
These findings offer insight into the workings of the alt-right and provide an example of how discourse analysis can be used in intelligence
gathering and research on these dangerous groups.

First, their layered crystal and electronic band structures are presented. Next, synthesis methods, such as mechanical exfoliation, liquid phase method, and vapor phase deposition, are summarized. Additionally, their device performance in field-effect transistors, photodetectors, spintronics, and 2D van der Waals heterostructures are presented. Finally, some conclusions and an outlook for future research are stated.
On improving the accuracy of self-calibrated stereo digital image correlation system
Authors: Iniyan Thiruselvam N , Subramanian S J 
Published: August 2020

Abstract
Stereo digital image correlation (stereo DIC), a full-field deformation measurement technique, is increasingly being used to resolve strains at µm-length scale by using microscope-like imaging systems. Self calibration of these imaging systems is more cost-effective and convenient than the conventional target-based calibration. Though the use of self-calibrated stereo DIC systems has already been reported, less attention has been paid to improving the accuracy of these systems. In the present work, we improve the accuracy of a self-calibrated stereo DIC system, which is composed of two full-frame DSLR cameras coupled to macro lenses and is used for testing ASTM E8M sub-sized flat dog-bone specimens. First, we collect the images of two of the speckled test specimens that subtend an angle of 12° between them using an f/25 aperture. Our image-collection strategy leads to a convergent imaging configuration with viewpoints that range from −45° to 45° across two perpendicular directions. Next, we process the collected images in a commercial photogrammetric calibration software by using more than nine image points for computing each object point. We validate our findings on a rigid-body motion test and a uniaxial tensile experiment, and we observe an excellent agreement between the stereo-DIC measurements and the ground truth. Using our findings, the reprojection error of self calibration is improved from 0.3 pixel to 0.1 pixel. The error in the stereo-DIC strain measurements is always less than 3.4% with the improvements made to self calibration, whereas it is as large as 7.6% without them.
Copper nanoparticle decorated non-woven polypropylene fabrics with durable superhydrophobicity and conductivity
Authors: Zhu Shimeng , Kang Zhixin , Wang Fen , Long Yan 
Published: August 2020

Abstract
In this study, a facile method was prepared to fabricate highly flexible, conductive and superhydrophobic polymer fabrics. Copper nanoparticles (CuNPs) were decorated on polypropylene fabrics using a simple spraying method and superhydrophobicity was obtained after vacuum drying for 4 h without any surface modifier. Accumulation of CuNPs constituted coral-like rough micro-nano structures, forming a stable Cassie model and endowing the surface with dense charge transport pathways, thus resulting in excellent superhydrophobicity (water contact angle ∼159°, sliding angle ∼2.3°) and conductivity (sheet resistance ∼0.92 Ω sq−1). The fabrics displayed superior waterproof and self-cleaning properties, as well as great sustainability in the water. Additionally, the superhydrophobicity and conductivity can be almost maintained after heat treatment, wear testing, water droplet impinging, weak alkali/acid treatment and repeated bending-kneading tests. These superhydrophobic and conductive fabrics that are free from moisture and pollution can be a reliable candidate to solve the water-penetration issue in the rapid development of flexible electronics.

Published: August 2020

Abstract
A voltage and power controlled surface dielectric barrier discharge for the removal of volatile organic compounds (VOCs) from gas streams is studied by means of current–voltage measurements, flame ionization detectors, and gas chromatography–mass spectrometry (GC–MS). The discharge is generated in a defined synthetic air gas stream at atmospheric pressure by application of a damped sinusoidal voltage waveform resulting from a resonant circuit. Multiple organic compounds, namely n-butane, butanol, isobutanol, ethyl acetate, diethyl ether, and butoxyethanol, are tested at concentrations of 50, 100, 200, and 400 ppm (parts per million), as well as peak-to-peak voltages of 8 to 13 kVpp and pulse repetition frequencies of 250 to 4000 Hz. The dissipated power within the system is calculated utilizing the measured voltage and current waveforms. The conversion and absolute degradation of the VOCs are determined by flame ionization detectors. An increasing concentration of VOCs is found to increase the dissipated power marginally, suggesting a higher conductivity and higher electron densities in the plasma. Of the applied VOCs, n-butane is found to be the most resistant to the plasma treatment, while higher concentrations consistently result in a lower conversion and a higher absolute degradation across all tested compounds. Corresponding amounts of converted molecules per expended joule are given as a comparable parameter by weighting the absolute degradation with the dissipated power. Finally, specific reaction products are determined by online GC–MS, further confirming carbon dioxide (CO2) as a major reaction product, alongside a variety of less prevalent side products, depending on the structure of the original compound. The findings of this study are intended to promote the development of energy efficient processes for the purification of gas streams in both, industry and consumer market. Potential applications of the presented technique could be found in car paint shops, chemical plants, hospital ventilation systems, or air purifiers for living space.
Cosmic acceleration caused by the extra-dimensional evolution in a generalized Randall-Sundrum model *

Abstract
We investigate an (n+1)-dimensional generalized Randall-Sundrum model with an anisotropic metric which has three different scale factors. One obtains a positive effective cosmological constant

(in Planck units), which only needs a solution

without fine tuning. Both the visible and hidden brane tensions are positive, which renders the two branes stable. Then, we find that the Hubble parameter is close to a constant in a large region near its minimum, thus causing the acceleration of the universe. Meanwhile, the scale of extra dimensions is smaller than the observed scale but greater than the Planck length. This may suggest that the observed present acceleration of the universe is caused by the extra-dimensional evolution.

Published: August 2020

Abstract
Given the insufficient cross-sectional data regarding the 14-MeV-neutron experiment of molybdenum, the vital fusion reactor structural material, and the significant heterogeneities among the reported values, this study examined the (n,2n), (n,α), (n,p), (n,d), and (n,t) reaction cross sections in molybdenum isotopes based on the neutrons produced via a T(d,n)4He reaction carried out in the Pd-300 Neutron Generator at the China Academy of Engineering Physics (CAEP). A high-resolution gamma-ray spectrometer, which was equipped with a coaxial high-purity germanium detector, was used to measure the product nuclear gamma activities. In addition, 27Al(n,α)24Na and 93Nb(n,2n)92mNb reactions were utilized as the neutron fluence standards. The experimental 92Mo(n,2n)91Mo, 94Mo(n,2n)93mMo, 100Mo(n,2n)99Mo, 98Mo(n,α)95Zr, 100Mo(n,α)97Zr, 92Mo(n,p)92mNb, 96Mo(n,p)96Nb, 97Mo(n,p)97Nb, 98Mo(n,p)98mNb, 92Mo(n,d)91mNb, and 92Mo(n,t)90Nb reaction cross sections were acquired within the 13–15 MeV neutron energy range. Thereafter, we compared and analyzed these obtained cross sections based on the existing IAEA-EXFOR database-derived experimental data, together with evaluation results corresponding to ENDF/B-VIII.0, JEFF-3.3, BROND-3.1, and CENDL-3.1 and the theoretical outcomes acquired through TALYS-1.95 and EMPIRE-3.2.3 (nuclear-reaction modeling tools).
Yield ratio of hypertriton to light nuclei in heavy-ion collisions from

Published: August 2020

Abstract
We argue that the difference in the yield ratio

measured in Au+Au collisions at

= 200 GeV and in Pb-Pb collisions at

= 2.76 TeV is mainly owing to the different treatment of the weak decay contribution to the proton yield in the Au+Au collisions at

= 200 GeV. We then use the coalescence model to extract from measured

the information about the

and nucleon density fluctuations at the kinetic freeze-out of heavy-ion collisions. We also show, using available experimental data, that the yield ratio

is a more promising observable than

for probing the local baryon-strangeness correlation in the produced medium.

AbstractA study on the preparation of Congo red textile dyes using nanocatalysts, Fe3O4@TiO2material, and Polyvinyl Pyrrolidone (PVP) has been successfully carried out. The preparation of these dyes is intended as a controller of the shape and size of particles and as a superior adhesive in solution. Fe3O4@TiO2core-shell (FTP) nanocomposite was carried out by coprecipitation method. The Fe3O4nanoparticles were designed as cores that were synthesized from Cilacap iron sand, while TiO2nanoparticles were selected as a shell through the synthesis of Titanium (III) chloride. Fe3O4@TiO2core-shell nanocomposite is characterized using X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Fourier Transform Infrared (FTIR), and UV-Visible Spectroscopic (UV-Vis). Through XRD data analysis, the crystalline nano-phase composite of Fe3O4@TiO2core-shell did not experience significant changes with the addition of Fe3O4concentration. The contribution of the addition of Fe3O4concentration can be observed in changes in sample grain size. The higher the concentration of Fe3O4is, the smaller the grain size of the samples produced, ranging between 6-9 nm and can increase the percentage of degradation of Congo red dyes. In addition, optimum degradation in UV-Vis characterization occurred in FTP 0.5 samples that reached 78.20% at minute 100. The photodegradation effect that occurs in Congo red dyes is caused by photocatalytic mechanisms.

Abstract
Transformer had been widely used for supplying electric power to many motors, such as electric pump, fans, or conveyors. The motor voltage may vary that is depending on its power and speed between one to another motor. The load needs the transformer which generate the proper voltage. Unfortunately, the working performance of transformer is slowly decreasing because of its daily operation. The repetition of the transformer technical assessment by observing the transformer performance is needed. This study provides the periodical inspection of high-power transformer in maintenance and outage condition in the one of utility sites in Indonesia. The checking activity maintenance the eligible performance of the user device. The measurement of Sweep Frequency Response Analysis (SFRA) in the 5th unit had been inspected once in every six years. The measured result was obtained in 2007 and 2013. SFRA test diagnoses the characteristics of transformer winding and core by injecting low voltage at a certain frequency. If SFRA diagnoses the winding fault, then the transformer should be replaced or should get a major maintenance. The result of SFRA measurement provides the transformer winding and core still in a good condition because the shrinkage does not exceed 20% of its standard percentage. Therefore, the 500 kV power transformer, located in PT. YTL East Java, does not have to get serious maintenance.

Abstract
In the context of energy efficiency, the control function of electrical equipment is an essential part of saving electricity consumption. That proven by several previous studies about the control of electrical equipment that has been successful for efficiency. In this study, electrical equipment will be controlled in public service buildings, using radio frequency (RF) and the internet. The realisation of this research is to make a radio frequency prototype and an internet-based light control device. For the buildings whose location is difficult to reach by the internet, light control uses radiofrequency. While for buildings that are affordable by internet access, using the internet to control the light. In this study, the microcontroller used is ESP 8266 MCU Node and TCM 3105 FSK IC Modem for connection to the internet. Device performance in running controls measured by the delay. Delay is the time difference between the command input time and the time the device has run the command. The average delay is at an average distance of 1513 ms at a distance of 1 m, 2844 ms at a distance of 10 m, 4674 ms at a distance of 100 m, 4060 ms at a distance of 150 m and 3151 ms at a distance of 300 m. The delay value decreases because, at distances of 100, 150, and 300 connections are lost. Under these conditions, the delay value is considered empty (0) so that the average decreases. The farther the distance, the higher the percentage of unconnected, this can be seen at distances of 100, 150, and 300 m.

Published: August 2020

Abstract
In this work, we report the effect of local sand ratio on compressive strength and dielectric properties of concrete. Concretes were made by mixing Portland cement mixed with local sand in various compositions of 1:2, 1:3.1:4.1:5, 1:6, and 1:7. These mixtures were printed in the form of 5×5×5 cm3 and have maintained (soaked) for 27 days. Specimens were characterized on the 28th day. Compressive strength was tested using the compression test and dielectric test with a series LCR meter. The compressive strength test results show that the more significant sand addition in the mixture decreases the compressive strength. Dielectric test results reveal that the higher addition of sand in the mixture reduces the dielectric constant. These results indicate that the dielectric constant measurement can be used as an alternative method for the investigation of concrete quality.

Abstract
The problem of ozone depletion lies behind the importance of developing a photodetector device, which is used as a preliminary detection step against the risk of solar radiation. At present, hybrid photodetectors are a major concern because they have detection and operational advantages over conventional photodetectors. In this study, we investigated the optical properties and photoresponse of hybrid ZnO/graphene (HZG) systems, of which ZnO nanorod (ZnO NR) was used in the system. Investigations were carried out using spectroscopic ellipsometry (SE) and solar simulators. The results of SE fittings with the effective medium approximation (EMA) method confirmed that the length of ZnO NR was 27.81, 42.67, and 220.46 nm respectively. We note that increasing the size of ZnO NR promotes light absorption to increase significantly. Furthermore, the relationship between light absorption and HZG photoresponse was discussed using a comprehensive analysis.

Abstract
Particle Swarm Optimization (PSO) is one of the algorithm intends to get minimum or maximum value of a function, based on the behavior of a bird flocks. In this research, PSO has implemented to overcome the problem of power flow in the plant. The search for solutions is carried out by a population of several individuals. Population is the representation of a generator in electric power distribution system. The plant used in this study is IEEE 30 bus. There are 6 plants which must be optimized. PSO generate one power value in each generator as a reference value. This value will be shifted by increasing or reducing it, until the optimal generation value is found for all plants. The result of the experiment proved that PSO is able to solve power flow optimization problems on IEEE 30 bus, indicated by the individual rate in each population, the rate of fitness and the rate of generation can reach its convergence. This convergence rate is strongly influenced by the value of Velocity on the PSO. With PSO method, the IEEE 30 bus system can generate optimal power of 193 MW.
