Authors: Izhar Rubina , Husain Samia , Tahir Muhammad Ahmad , Husain Sonia 
Published: July 2022

Background: The purpose of this study was to assess the effect of combining low dose of Coenzyme Q10 with clomiphene citrate on ovulation induction in polycystic ovary syndrome (PCOS) women with clomiphene resistance.
Methods: A total of 149 women with clomiphene resistant PCOS who needed ovulation induction were randomly allocated to oral clomiphene citrate and Coenzyme Q10 group and oral clomiphene citrate only group using a computer generated allocation sequence. The study was conducted at Aziz Medical Center, Karachi, Pakistan from 1st July 2020 to 1st October 2020. Polycystic ovary syndrome was diagnosed according to Rotterdam criteria. The primary outcome was ovulation and conception rate per cycle. Chi square test and Fischer’s exact test were used to compare these variables at p<0.05 level of significance.
Results: Of the 133 women assessed, the proportion of women who ovulated with combination (70% vs., 19%, p=0.001) was greater and the combination group had greater conception rate per cycle than those who received only clomiphene (48.6% vs. 6.3%, p˂0.001). When stratified according to obesity, 85.3% of non-obese women who received combination ovulated whereas only 55.6% of obese women ovulated (p=0.002). Moreover, 48.6% of non-obese women conceived in the combination group as compared to 6.3% of obese women (p=0.007). Women who received combination were six times more likely to conceive than women who only received clomiphene citrate (AOR=6.344, 95% CI: 1.452-27.71, p=0.014).
Conclusion: Coenzyme Q10 is a valuable adjunct in women with PCOS undergoing ovulation induction. It improves ovulation and conception in women with clomiphene resistance.

Background: The cases with unexplained infertility may have an abnormality in their sperm chromatin structure. Sperm selection methods can be used to separate sperm with low DNA fragmentation. The purpose of this study was to compare the efficacy of physiological intracytoplasmic sperm injection (PICSI) with magnetic-activated cell sorting (MACS) in assisted reproductive techniques in cases with unexplained infertility.
Methods: The semen samples were collected from couples with unexplained infertility. After semen analysis and sperm DNA fragmentation (SDF) evaluations, samples were prepared with swim-up method. The rates of SDF in different fractions including raw semen (n=20), swim-up (n=20), only motile sperm after swim-up (swim-up selection) (n=20), MACS sperm selection (n=20), only motile sperm after MACS (MACS selection) (n=20), and PICSI sperm selection (n=16) were evaluated. Also, the main sperm characteristics and fine morphology of sperm suspension after MACS were assessed. Statistical analysis was performed using GraphPad Prism. The p<0.05 was considered statistically significant.
Results: DNA fragmentation index (DFI) values in PICSI and MACS groups were significantly reduced as compared to the swim-up group. The rate of this reduction was more pronounced in MACS (58.20±13.02) than PICSI (36.57±15.52) group. Also, our results showed that MACS resulted in decreased sperm motility, with no alteration in their fine morphology.
Conclusion: MACS was found to be more efficient in reduction of SDF rates than PICSI. However, none of the sperm selection techniques can not totally eliminated the spermatozoa with DNA fragmentation in the final sperm sample.
Gender Performativity in Perumal Murugan’s Estuary
Authors: Mizpah R 
Published: July 2022

Purpose of the study: The study aims to trace how the author has portrayed the characters in ways that they perform in specific ways to generate various effects that determine their gender roles. It aims to map gender performativity in the novel Estuary by close reading and analysing the acts and dialogues of the characters from a cultural context.
Methodology: Qualitative analysis of the text was done to derive the findings. The text was subjected to close reading. The points relevant to the concept of gender performativity were highlighted using a pencil. The points were neatly organized and classified using a notebook. The points were developed into an essay by using critical thinking. Views from other disciplines such as psychology are incorporated making the study an interdisciplinary one.
Main Findings: Though Perumal Murugan alters the stereotypical gender roles of Meghas’ parents at specific points in the novel, he reinforces them a more significant number of times than when he changes them. With his sarcasm as a tool, he supports Kumarasurar and Mangasuri as typical Indian parents of the 21st century, thereby stereotyping them in the novel.
Applications of the study: This study will be useful in the fields of gender studies, cultural studies, domestic studies, the study of 21st century Tamil culture, South Asian studies, South Indian culture, etc.
Novelty/Originality of the study: The study jots down the various ways in which gender is performed by a typical Tamil couple. Translated Tamil novels are rarely studied using the emerging literary theories including gender performativity. As the present analysis of the novel breaks down how gender is performed by the characters, it contributes to the field of gender studies as well as research on Tamil novels translated to English.
The syntax of existential constructions
Authors: Izre'el Shlomo 
Published: July 2022

This study, in two parts, endeavors a novel analysis of existential constructions, based on a different theoretical setting of clause structure, where the predicate is taken as a necessary and sufficient constituent of the clause. Leaning on this perception, the analyses of existential constructions developed here tries to overcome the discrepancy between form and (semantic and informational) meaning in Hebrew existential constructions. The main part of the study deals with affirmative existential-presentative constructions, used to introduce referents into the discourse. Most of the constructions have been analyzed as consisting of an existential constituent, viewed as a modal marker, and a pivot, regarded as the core component of the predicate domain. This analysis is shown to be valid for both the existential marker jeʃ and for its suppletive verbal forms, derived from √hjj ‘be’. A distinction is made between verbal forms with non-referential and referential verb-bound person markers, where the latter, found with expected, known or given pivots, function as focus marking devices, coming in complementary distribution with prosodic marking of focus. Thus, presentative-existential sentences are formed as unipartite sentences, consisting of only a predicate domain. The last two sections of Part I deal with constructions where the existential constituent follows the pivot and with constructions where the pivot is definite. Part II deals with other existential constructions, including negative constructions; bipartite existential sentences; existential constituents as sole constituents in a sentence; existential constituents with clitic referential markers; and the use of existential markers as interjections or discourse markers.

Authors: Cardoso Danielle Engel Cansian , Ens Romilda Teodora 
Published: July 2022

O artigo objetiva analisar a Resolução CNE/CP n.º 2/2019, a qual define as Diretrizes Curriculares Nacionais para a Formação Inicial de Professores para a Educação Básica e institui a Base Nacional Comum para a Formação Inicial de Professores da Educação Básica (BNC-Formação). Temos como pressuposto que o acesso por ações afirmativas às instituições de educação superior no Brasil insere nas salas de aula sujeitos de diferentes culturas, origem social e econômica e que políticas de acesso por ações afirmativas não encontram no currículo, na estrutura e na organização das IES elementos que atendam a essa realidade. Pela pesquisa de abordagem qualitativa, pesquisa bibliográfica e documental, foi possível apreender e compreender sobre: políticas de ações afirmativas; teoria pós-crítica do currículo e desafios da educação intercultural. Na análise de conteúdo da Resolução CNE/CP n.º 2/2019 (BRASIL, 2019, 2020), buscamos estabelecer a presença e/ou ausência de elementos representativos das ações afirmativas e da teoria pós-crítica do currículo, pela abordagem da interculturalidade e os desafios que envolvem essa forma de considerar a educação. Os resultados indicam que a teoria pós-crítica do currículo, ancorada pela interculturalidade do multiculturalismo, se colocada em prática, poderá atender aos estudantes ingressantes na educação superior, mas os desafios continuam, uma vez que o novo desenho político da formação inicial desconsidera as condições sociais, históricas e econômicas em que a Formação de Professores se efetiva por estar voltada à lógica do mercado.

Published: July 2022

Summary
For steamflooding processes, steam quality plays a crucial role because it affects enhanced oil recovery mechanisms and production performance. Many numerical simulations have been performed on the role of steam quality. However, few studies have evaluated the role of steam quality on steamflooding performance by experimental measurements because of the lack of a generalized experimental methodology to accurately generate and measure steam with different qualities under reservoir conditions. The objective of this study is to propose a generalized experimental methodology for investigating the role of steam quality on steamflooding performance. A steam quality controlling box was newly designed and fabricated to generate steam with different qualities, and its reliability was verified by a novel steam quality measurement system together with a developed theoretical method. Then, a series of experiments were conducted by our designed 1D and 2D sandpack models to evaluate the steamflooding performance under different steam qualities. The results showed that the developed methodology could accurately generate and measure steam with different steam qualities. The maximum errors between desired, measured, and calculated steam qualities were 4.39% under the experimental conditions in this study. The steam quality substantially affected the steamflooding performance. A higher steam quality led to a lower water cut, a lower maximum pressure difference between the inlet and outlet of the sandpack model, a lower water/oil ratio (WOR), a lower steam/oil ratio (SOR), a higher oil recovery, and a higher oil production rate. However, there is an optimal value of steam quality from the view of heat efficiency in this study. The oil recoveries of 2D steamflooding experiments increased from 36.30 to 45.02% when the steam quality increased from 0 to 0.8. However, the optimal steam quality of 0.6 had the maximum heat efficiency at 3.16×10−5 kJ−1. This research contributes to a better understanding of steam quality on steamflooding performance and also provides a generalized methodology for other steam injection processes.

Summary
As the world’s demands for energy and water increase, innovative technologies have been implemented to produce more energy and water, sometimes in unconventional fields. It brought in new challenges of highly saline water formation and souring of wellbore or formation. Under these circumstances, the conventional threshold inhibition methods might be ineffective in controlling mineral scales. To develop a new feasible method to manage more difficult mineral scale problems, we investigated a single approach to prevent complex mineral scales from deposition using a water-soluble polymer of carboxymethyl cellulose (CMC). We also examine the effect of the combination of conventional threshold scale inhibitors and CMC for complex mineral scale control. Our results showed that a polymeric dispersant of CMC successfully prevented zinc and lead sulfide, barium and calcium sulfate, and calcium and iron carbonate scales from deposition, similar to what we had observed previously with iron sulfide. CMC combined with phosphonate inhibitors of diethylenetriamine penta(methylene phosphonic) acid (DTPMP) or hexamethylene diamine tetra(methylene phosphonic) acid (HDTMP) also enhanced the inhibition performance of phosphonate inhibitors. PbS and ZnS were successfully dispersed in the presence of CMC as low concentrations of CMC as 2 mg/L for PbS and 5 mg/L for ZnS in solution passed through a 1.2-μm pore-size membrane. For barite scale control, the combination of CMC and DTPMP inhibited barite formation for 2 hours, while CMC for only 5 minutes and DTPMP for 18 minutes. The mass of barite deposit on 316 stainless steel was reduced by three-order magnitudes in the combination of DTPMP and CMC, compared with DTPMP alone. The scanning electron microscope (SEM) image of barite precipitated in CMC and DTPMP showed that its morphology was no longer a rhombic plate. According to the transmission electron microscope (TEM) image, the surface of barite was covered by CMC, and after a 6-hour reaction, its size was 45.6 nm, which was slightly larger than that at induction time (10–35 nm). Gypsum crystal formation was also inhibited for at least 6 hours in combining CMC and HDTMP. For calcite scale control in the presence of 20 mg/L of CMC, calcite formations and growth were prevented for 134 minutes, and particle sizes remained in the nanosize range (average particle size of 396 nm) for a 15-hour reaction. Iron carbonate treated with 200 mg/L of CMC-250k and CMC-700k was dispersed for at least 2 hours under our experimental conditions. This study demonstrated that CMC effectively performed as a universal dispersant bringing a new feasible method to manage complex mineral scale problems.
Exploring the Nature of the Fine-Structure Constant in the Setting of General Relativity, Quantum Physics, and the Evolution of the Universe
Authors: Williams Lamont 
Published: July 2022

Abstract
This study explores the possibility that the value of the fine-structure constant, α, is linked to the spacetime geometry of the electromagnetic field between two elementary charges, connecting the smooth manifold responsible for gravity with the discreteness of the electromagnetic field. In a step-by-step manner, the study presents a logical basis for the establishment of a fundamental equation for α. It is shown that the equation is directly linked to experimental data involving elementary electric charge, e, and resolves the problems of the Landau pole (when the value of e is infinite at a finite energy level) and triviality (when the value of e is zero at an infinite energy level) in quantum electrodynamics. The equation is also consistent with the evolution of the universe—here, a near-perfect match exists between specific points along the line representing the running of the constant’s value by way of the equation and important periods in the universe’s development. The presented concepts have the potential to assist in efforts to determine how the value of α might be directly derived within the Standard Model.
Electromotive Force Generated in All Materials under Temperature Difference
Authors: Song Dong-il 
Published: July 2022

Abstract
In this research, we investigate the thermoelectric effects of general materials. The results of this showed that an electromotive force was generated under a temperature difference between two points in materials. As no material has infinite electric resistance, an electromotive force is expected to be generated under a temperature difference in all materials. In conclusion, the thermoelectric effect generates an electromotive force. This electromotive force causes an electric current to flow, thereby generating a magnetic field.This magnetic field generates the Earth's magnetic field, triboelectricity, sunspots, and kinetic energy of celestial bodies.This temperature differential electromotive force also generates lightning and creates an ionosphere that reflects radio waves.
High coherent supercontinuum generation in nitrobenzene liquid-core photonic crystal fiber of elliptical air-hole inner ring

Published: July 2022

Abstract
A nitrobenzene liquid-core photonic crystal fiber (NLC-PCF) is proposed in this work. The eight elliptical air-holes in the innermost ring of the cladding of the fiber structure can contribute to flexibly regulating dispersion and restraining the fiber core. The appreciable dispersion is realized by adjusting the structural parameters of NLC-PCF, which is characterized by three zero-dispersion wavelengths (ZDWs), flat dispersion with the fluctuation of fewer than 40 ps·nm− 1·km− 1, and high nonlinearity as high as 5500 W− 1·km− 1. The propagation of femtosecond pulse and supercontinuum generation (SCG) in NLC-PCF is studied numerically when the pump wavelength is located in the normal and abnormal dispersion region near different ZDW through solving the generalized nonlinear Schrödinger equation (GNLSE) by the split-step Fourier method. The numerical results show that a highly coherent supercontinuum (SC) spanning from 1.3 to 2.8 µm is obtained when the pump pulse with the center wavelength of 1910 nm, the peak power of 1000 W, and pulse width of 50 fs propagated in the 5 cm long NLC-PCF. This research can find applications in the fields of novel liquid-core PCF design and ultrashort pulse propagation.

Published: July 2022

Abstract
In cellular networks, the performance of the adaptive beamforming algorithms is severely degraded by the presence of the interfering signals. In this paper, we introduce a beamforming based algorithm for 5G applications named Direction Finding for Beamforming and Synthesizing (DFBS). This algorithm combines the Direction of Arrival (DOA), adaptive beamforming, and the radiation pattern synthesizing. The proposed algorithm uses the DOA technique to feed the adaptive beamforming algorithms with estimations of the desired user direction, desired user signal, and the interfering signals with their directions as initial values. In addition, we use the adaptive beamforming process to supply the radiation pattern synthesizing algorithms with an initial radiation pattern, and the required positions of nulls. At the beamformer output, we evaluate our proposed mechanism in terms of the error convergence, tracking capabilities, and the obtained radiation pattern characteristics. At the synthesizer output, we carry out analysis in terms of the convergence speed and the resultant radiation pattern attributes to investigate the efficiency of the proposed algorithm. The simulation results show that, our proposed algorithm has significantly fast convergence, reliable tracking capabilities, and radiation patterns with very low Side Lobe Levels (SLL).2010 MSC: 00-01, 99-00
