Abstract
Synthetic ester can replace the mineral oil traditionally used in transformers to avoid the environmental problems caused by oil leakage. However, the fast discharge phenomenon in a high electric field in transformers using synthetic ester seems to indicate its insulation property is inferior to that of mineral oil. In this paper, typical molecular models of synthetic ester, including F2, F4, F6, F8, and F10, are constructed. We studied the effect of electric fields on the molecular properties of the five molecules by density functional theory and time-dependent density functional theory. According to the electric field intensity required for discharge initiation and propagation in insulating oil, the electric field intensity applied in this study varied from 108 to 109 V/m. The results showed that the molecular bond lengths are obviously dependent on the electric field. The ionization potential (IP) of the F8 and F10 molecules decreases sharply under electric field intensities of 3.1 × 109 and 4.0 × 109 V/m. It can be inferred that the IP reduction of the long carbon chain molecules, such as F8 and F10, is the reason for the formation of fast discharge in the case of synthesis ester. Calculations for excited states show that the introduction of an electric field makes the electron transition more active. The results obtained by this work improve our understanding of the discharge mechanism in synthetic ester dielectrics and provide theoretical support for improvement in the performance of synthetic ester insulating oil.

Abstract

Background
Procalcitonin (PCT) measurement is required for intensive care patients with systemic inflammation symptoms, early diagnosis of possible infections, and evaluation of sepsis severity and prognosis.

Objectives
We aimed to determine the analytical performance of PCT measurement in a Roche Modular E170 (ECLIA) analyzer and compare the performance with VIDAS (BRAHMS/ELFA) analyzer findings.

Material and methods
Within-day and between-day precision value, linearity was determined, and two methods were compared with regression and Bland–Altman analysis.

Results
Both ECLIA and ELFA assays indicated excellent precision, where within-day precision varied between 1.18% and 3.97% CV, and between-day precision varied between 1.77% and 3.93% CV. The ECLIA method was linear up to 62.15 ng/mL. The arithmetic mean was 6.02 ng/mL with the ECLIA method and 8.02 ng/mL with the ELFA method. The correlation coefficient was r=0.996 and p=0.001. The correlation was linear between the two methods. Regression equation was found y=0.78x − 0.23. The Bland–Altman figure was revealed the difference between the methods was specifically in lower concentrations (<0.15 ng/mL).

Conclusions
Both methods show good precision and correlation. It was determined that the difference between methods was significant, especially at <0.15 ng/mL concentration.
One-dimensional Wiener process with the properties of partial reflection and delay

Published: November 2021

In this paper, we construct the two-parameter semigroup of operators associated with a certain one-dimensional inhomogeneous diffusion process and study its properties. We are interested in the process on the real line which can be described as follows. At the interior points of the half-lines separated by a point, the position of which depends on the time variable, this process coincides with the Wiener process given there and its behavior on the common boundary of these half-lines is determined by a kind of the conjugation condition of Feller-Wentzell's type. The conjugation condition we consider is local and contains only the first-order derivatives of the unknown function with respect to each of its variables.
The study of the problem is done using analytical methods. With such an approach, the problem of existence of the desired semigroup leads to the corresponding conjugation problem for a second order linear parabolic equation to which the above problem is reduced. Its classical solvability is obtained by the boundary integral equations method under the assumption that the initial function is bounded and continuous on the whole real line, the parameters characterizing the Feller-Wentzell conjugation condition are continuous functions of the time variable, and the curve defining the common boundary of the domains is determined by the function which is continuously differentiable and its derivative satisfies the Hölder condition with exponent less than $1/2$.

The electrochemical processes in capacitor systems based on porous carbon materials (PCMs) derived from glucose, lactose, and saccharose at activation temperature of 800 and 1000°C are explored using impedance spectroscopy method. An equivalent electric circuit, which allows modeling of the impedance spectra in the frequency range from 10-2 to 105 Hz, is proposed, and a physical interpretation of each element of the electrical circuit is presented. It is set that in capacitor systems on the basis of the explored materials the accumulation of capacitance occurs due to the formation of a double electric layer at the electrode/electrolyte boundary, and Faradaic processes are minimized. The specific capacity of supercapacitors based on PCMs obtained at 800°C is 91-154 F/g due to the developed microporous structure of materials.
A Timokratés elleni beszéd érvrendszerei

Published: November 2021

Jelen tanulmány célkitűzése kettős. Egyrészt a Timokratés elleni beszéd érvrendszereinek mélyreható elemzését kívánom nyújtani, másrészt ezen elemzésen keresztül a XIX. században felmerült és azóta is sokat vitatott szövegkritikai problémákat veszem górcső alá. Új aspektusból közelítve a korábban felvetett problémákhoz – az érveléstechnika elemzésén keresztül kiegészítve E. M. Harris meggyőző érveit – amellett érvelek, hogy a beszéd két része valójában egy jól átgondolt, precízen szerkesztett egészet alkot, így a szöveg integritását nem indokolt megkérdőjelezni.The current study has two objectives. On the one hand, it provides an in-depth analysis of the argumentation of the oration Against Timocrates. On the other hand, the analysis focuses on the issues of textual criticism that arose in the 19th century and have been debated ever since. Approaching the problems from a new perspective – augmenting the convincing arguments put forward by E. M. Harris with the analysis of the argumentation – the study argues that the two halves of the speech are in fact parts of a well-planned, and precisely edited whole, and the integrity of the text need not be questioned.

Gender Inequality And Economic Development: Evidence From Sub-Sahara Africa
Authors: Onogwu Daniel Joseph 
Published: November 2021

Abstract
In developed countries, there is a substantial gender convergence over the last century. This cannot be said for Sub-Sahara Africa. Women are underrepresented in most economic and political spheres of the region. The implication is that the productivity of men increases relative to women thus decreases the supply of women’s labor force and increases the supply of men’s labor force. This study provides evidence of gender inequality on economic development in the Sub-Sahara Africa region. I conduct panel regression of 29 Sub Sahara African countries over the period from 1996 to 2019. Our results show that there is a significant negative impact of gender inequality on economic development in the region, holding other variables constant. Conversely, gender parity will positively affect economic development as evidence in our results. I also find that, Capital accumulation (proxy as Gross Capital Formation), trade openness and population growth are key drivers of economic development of the region. I recommend policies that promote gender equity, trade openness, and growth of healthy population to promote economic development in the region.JEL: A, B, E, H, J, O,
Multilayer Methylcellulose Substrate-Based Wearable Touch Sensor and Display for Communication

Published: November 2021

Abstract
In recent years, flexible printed circuit boards (FPCBs) that have polyimide substrates have been widely used in electronic devices for industrial and academic research owing to their light weight, high dielectric constant, and flexibility. However, these FPCBs have a critical limitation of recycling, as polyimide is not degradable or eco-friendly. To overcome this issue, we fabricated cellulose-based FPCBs. Transparent and flexible methyl cellulose-based substrate was produced through a simple solvent evaporation process. The circuit layer was patterned of an Ag/carbon-nanotube composite fabricated using a stencil mask. The methyl cellulose-based FPCBs were evaluated for diverse mechanical stresses such as bending, torsional, and tensile stresses. In addition, their surface morphology was analyzed using optical microscopy and scanning electron microscopy. For the electrical properties, in addition to the current–voltage curves, their dielectric properties were analyzed. Finally, we reported the successful wearable communication device of the cellulose-based FPCBs in a 5 × 5 touch panel and a 5 × 5 light-emitting diode display.

Abstract
Obesity, as one of the major public health problems in the world, has attracted more and more attention. Rb1 is the most abundant active component of Panax ginseng and it has been reported to have benefit effects on obesity and diabetes. But the mechanisms of Rb1 in regulation of obesity are not very clear. In this study, by use of obese mice, we found that Rb1 not only reduced body weight but also decreased myostain (MSTN) expression,which plays a vital part in the regulation of obesity. In vitro, we found that Rb1 treatment also decreased MSTN expression in differentiated C2C12 cells (Myoblast cells) and 3T3-L1 cells (adipocytes). Fndc5, as the downstream of MSTN, was increased after Rb1 treatment. Conclusions﻿Our results showed that Rb1 may ameliorate obesity in part through MSTN/Fndc5 signaling pathway. Our study provides important experimental evidences for the treatment of obesity by Rb1.

Abstract
Microgravity is one of the most important abiotic stresses in space. In the case of plant exposure to short term microgravity, plants establish strategies to response to these stresses and promote growth and survival. We hypothesized that the simulated microgravity can promote the antioxidant capacity and the formation of secondary metabolites such as tropane alkaloids in the Hyoscyamus niger. Callus induction was conducted by putting hypocotyl segments of H. niger seedlings in solid MS medium supplemented with 1 mg L−1 2,4-D and 1 mg L−1 BAP growth regulators. Then, the sub-cultured calli were placed on a clinostat for 3, 7 and 10 days. We performed Atropine and Scopolamine determination through HPLC. PAL (Phenyle alanine amonalyase) and antioxidant activity were also determined. Gene expression analysis of jasmonic acid (JA), Hyoscyamine 6-beta Hydroxylase (H6H), Putrescine N-methyltransferase (PMT), mitogen-activated protein kinase (MAPK) and ethylene responsive element binding (EREB) was performed using quantitative real time PCR. Findings showed that microgravity had a positive effect on the antioxidant capacity, Atropine and Scopolamine production in the H. niger calli. However, microgravity had a negative effect on the PAL activity. Furthermore, gene expression analysis indicated that microgravity significantly induced gene expression of the H6H, PMT and JA. It was also revealed that callus growth, carbohydrate and protein content increased in response to microgravity treatment. We conclude that microgravity can be considered as a potent factor to induce plant antioxidant activity and tropane alkaloids formation to be applicable in the pharmaceutical and medicinal industries.

Abstract
Cervical cancer affects over half a million people worldwide each year, the majority of whom are in resource-limited settingswhere cytology screening is not available. As persistent human papilloma virus (HPV) infections are a key causative factor,detection of HPV strains now complements cytology where screening services exist. This work demonstrates the efficacy of ahandheld Lab-on-Chip (LoC) device in detecting cervical cancer from biopsy samples. The device is based on Ion-SensitiveField-Effect Transistor (ISFET) sensors used in combination with loop-mediated isothermal amplification (LAMP) assays, toamplify HPV DNA and human telomerase reverse transcriptase (hTERT) mRNA. These markers were selected because of theirhigh levels of expression in cervical cancer cells, but low to nil expression in normal cervical tissue. The achieved analyticalsensitivity for the molecular targets resolved down to a single copy per reaction for the mRNA markers, achieving a limit ofdetection of 102for hTERT. In the tissue samples, HPV-16 DNA was present in 4/5 malignant and 2/5 benign tissues, withHPV-18 DNA being present in 1/5 malignant and 1/5 benign tissues. hTERT mRNA was detected in all malignant and nobenign tissues, with the demonstrated pilot data to indicate the potential for using the LoC in cervical cancer screening inresource-limited settings on a large scale
