UTILIZING SHORT STORIES TO IMPROVE VOCABULARY OF 8th GRADERS JUNIOR HIGH SCHOOL

This study was conducted to analyze the use of English short stories to improve the vocabulary mastery of 8th grade students at a public junior high school in Surabaya and their perceptions towards the use of English short stories. The researcher used the Classroom Action Research (CAR) method, involving 28 students (13 males, 15 females) with varying abilities. Data was collected through tests and interviews related to the use of English short stories. According to the analysis, this study revealed that English short stories helped students improve their vocabulary skills (Mean: 68 > 72 > 80). Moreover, the students also had a positive perception of the use of English short stories.
A Survey of the Classification of Division Algebras

For a given field F we seek all division algebras over F up to isomorphism. This question was first investigated for division algebras of finite dimension over F by Richard Brauer. We discuss the construction of the Brauer group and some examples. Crossed products and PI algebras are then introduced with a focus on Amitsur’s non-crossed product algebra. Finally, we look at some modern results of Bell on the Gelfand-Kirillov dimension of finitely generated algebras over F and the classification of their division subalgebras.
Budgets of turbulent kinetic energy, Reynolds stresses, variance of temperature fluctuations and turbulent heat fluxes in a round jet

The self-preserving region of a free round turbulent air jet at high Reynolds number is investigated experimentally (at $x/D=30$ , $\mathit{Re}_{D}=1.4\times 10^{5}$ and $\mathit{Re}_{{\it\lambda}}=548$ ). Air is slightly heated ( $20\,^{\circ }\text{C}$ above ambient) in order to use temperature as a passive scalar. Laser doppler velocimetry and simultaneous laser doppler velocimetry–cold-wire thermometry measurements are used to evaluate turbulent kinetic energy and temperature variance budgets in identical flow conditions. Special attention is paid to the control of initial conditions and the statistical convergence of the data acquired. Measurements of the variance, third-order moments and mixed correlations of velocity and temperature are provided (including $\overline{vw^{2}}$ , $\overline{u{\it\theta}^{2}}$ , $\overline{v{\it\theta}^{2}}$ , $\overline{u^{2}{\it\theta}}$ , $\overline{v^{2}{\it\theta}}$ and $\overline{uv{\it\theta}}$ ). The agreement of the present results with the analytical expressions given by the continuity, mean momentum and mean enthalpy equations supports their consistency. The turbulent kinetic energy transport budget is established using Lumley’s model for the pressure diffusion term. Dissipation is inferred as the closing balance. The transport budgets of the $\overline{u_{i}u_{j}}$ components are also determined, which enables analysis of the turbulent kinetic energy redistribution mechanisms. The impact of the surrogacy $\overline{vw^{2}}=\overline{v^{3}}$ is then analysed in detail. In addition, the present data offer an opportunity to evaluate every single term of the passive scalar transport budget, except for the dissipation, which is also inferred as the closing balance. Hence, estimates of the dissipation rates of turbulent kinetic energy and temperature fluctuations ( ${\it\epsilon}_{k}$ and ${\it\epsilon}_{{\it\theta}}$ ) are proposed here for use in future studies of the passive scalar in a turbulent round jet. Finally, the budgets of turbulent heat fluxes ( $\overline{u_{i}{\it\theta}}$ ) are presented.
Secondary School Teachers’ Perceptions of the Qualities of Effective EFL Teachers in Saudi Arabia

This study examined the perceptions of 138 Saudi secondary school male English teachers in Riyadh regarding the qualities of an effective EFL teacher. It aimed to investigate these qualities and explore the relationship between teachers’ experiences and perceptions. A survey research design was used, with data collected through a 5-point Likert-scale questionnaire. Descriptive analysis and an independent t-test were conducted. The findings revealed that effective EFL teachers possess various qualities in personal quality, attitude, pedagogical knowledge, subject matter knowledge, and classroom practice. Teachers considered all these qualities essential. However, no significant relationship was found between teachers’ experience and their perceptions of effective EFL teacher characteristics.
COMPREHENDING THE CHARACTERISTICS AND EFFECTS OF THE HEALTH MISINFORMATION - A STUDY AMONG SOCIAL MEDIA USERS

Social media has become the most accessible and considered to be trustworthy media for accessing health related information with immediacy. This has led to the creation, development and spread of misinformation too. Prevalence of misinformation can be detrimental to the quality of life and sometimes may lead to even death and hence it becomes more essential to understand the complexities of dealing with such misinformation. Being aware of the menace of the situation, we also recognize the need to fight against misinformation. For this purpose, we need to focus on categorization of the main topics of health misinformation and an all-inclusive depiction of their pervasiveness on various social media, the influence it has on the minds and health behavior of people. Such a detailed analysis will enable us to develop future digital policy action plans towards misinformation. Against this background the objectives of the study are to identify the characteristics of health misinformation on social media; and the factors that influence the people’s belief and behavior towards health misinformation circulated online. A descriptive survey with convenience sampling technique among social media users will be applied for understanding how various people perceive and are susceptible to the problems of misinformation. Proper understanding of the features of health misinformation in the social media will facilitate us to focus on the measured ways to eradicate the fatal impact of misinformation. Our perceptions on the misinformation that prevails in the fields of health and emergency management will improve through the data gathered and presented in this study.
Study of ϒ Production and Cold Nuclear Matter Effects in pPb Collisions at √s[subscript NN] = 5 TeV

The production of J/ψ mesons with rapidity 1.5 < y < 4.0 or −5.0 < y < −2.5 and transverse momentum pT < 14 GeV/c is studied with the LHCb detector in proton-lead collisions at a nucleon-nucleon centre-of-mass energy √ sNN = 5 TeV. The J/ψ mesons are reconstructed using the dimuon decay mode. The analysis is based on a data sample corresponding to an integrated luminosity of about 1.6 nb−1. For the first time the nuclear modification factor and forward-backward production ratio are determined separately for prompt J/ψ mesons and J/ψ from b-hadron decays. Clear suppression of prompt J/ψ production with respect to proton-proton collisions at large rapidity is observed, while the production of J/ψ from b-hadron decays is less suppressed. These results show good agreement with available theoretical predictions. The measurement shows that cold nuclear matter effects are important for interpretations of the related quark-gluon plasma signatures in heavy-ion collisions.
Role of singularities in hydrodynamics

Some of the most interesting structures observed in hydrodynamics are best understood as singularities of the equations of fluid mechanics. Examples are drop formation in free-surface flow, shock waves in compressible gas flow, or vortices in potential flow. These examples show that singularities are characteristic for the tendency of the hydrodynamic equations to develop small scale features spontaneously, starting from smooth initial conditions. As a result, new structures are created, which form the building blocks of more complicated flows. The mathematical structure of singularities is self-similar, and their characteristics are fixed by universal properties. We review recent developments in this field through the lens of one of the great scientific challenges of today: understanding the structure of turbulence.
Irritable bowel syndrome: Epidemiology, overlap disorders, pathophysiology and treatment

Irritable bowel syndrome (IBS) is a common chronic gastrointestinal disease with a significant impact on patients’ quality of life and a high socioeconomic burden. And the understanding of IBS has changed since the release of the Rome IV diagnosis in 2016. With the upcoming Rome V revision, it is necessary to review the results of IBS research in recent years. In this review of IBS, we can highlight future concerns by reviewing the results of IBS research on epidemiology, overlap disorders, pathophysiology, and treatment over the past decade and summarizing the latest research.
Development of an Implicit Physical Influence Upwind Scheme for Cell-Centered Finite Volume Method

Abstract—An essential component of a finite volume method (FVM) is the advection scheme that estimates values on the cell faces based on the calculated values on the nodes or cell centers. The most widely used advection schemes are upwind schemes. These schemes have been developed in FVM on different kinds of structured and unstructured grids. In this research, the physical influence scheme (PIS) is developed for a cell-centered FVM that uses an implicit coupled solver. Results are compared with the exponential differencing scheme (EDS) and the skew upwind differencing scheme (SUDS). Accuracy of these schemes is evaluated for a liddriven cavity flow at Re = 1000, 3200, and 5000 and a backwardfacing step flow at Re = 800. Simulations show considerable differences between the results of EDS scheme with benchmarks, especially for the lid-driven cavity flow at high Reynolds numbers. These differences occur due to false diffusion. Comparing SUDS and PIS schemes shows relatively close results for the backward-facing step flow and different results in lid-driven cavity flow. The poor results of SUDS in the lid-driven cavity flow can be related to its lack of sensitivity to the pressure difference between cell face and upwind points, which is critical for the prediction of such vortex dominant flows.
Associated Factors of Exclusive Breastfeeding Intention among Pregnant Women in Najran, Saudi Arabia

The exclusive breastfeeding (EBF) intention conceived by pregnant women is the most important predictor of breastfeeding (BF) initiation, duration, and continuation. This study explores the associated factors of EBF intention among pregnant women. This was a descriptive cross-sectional study conducted from November 2022 to January 2023 with 382 pregnant women who came to the outpatient clinic in the Maternal and Children Hospital (MCH). Four instruments were used for data collection: the Infant Feeding Intention scale, the Gender-Friendly BF Knowledge scale (GFBKS), the Iowa Infant Feeding Attitude scale (IIFAS), and the basic data questionnaire. The study findings indicated that 51.8% and 75.9% of gravida women had adequate knowledge and a positive attitude regarding BF. Furthermore, 56.3% of the participants had a high intention for EBF. Binary logistic regression illustrated that occupational status, antenatal care, plan for the current pregnancy, BF practice, last child delivery mode, medical disorder during the current pregnancy, age, BF knowledge, and attitude are potential predictors. The goodness of fit test revealed that 46.8% of the EBF intention could be anticipated through the positive pre-mentioned factors. The low EBF intention is modifiable by addressing the previously positive predictors. BF educational interventions should be tailored based on EBF intention predictors in order to be effective and lead to behavior change.

Objective: This study aims to determine the prevalence, indications, common findings, challenges, and complications of gynaecological pan-endoscopy in Obafemi Awolowo University Teaching Hospitals Complex, Osun State. Methods: It was a retrospective study. Records of patients who had gynaecological hysteroscopy and (or) Laparoscopy from 1st January 2012 to 31st December 2021 were retrieved, and relevant data were extracted and analyzed using the SPSS version 21.0 Results: There were 2125 gynaecological surgeries within the study period, with 207 endoscopies giving a prevalence of 9.7%. Infertility 100 (51.5%) was the most common indication. Common findings were tubal block 45(33.6%) and intrauterine adhesions 19 (31.7%). The most common complication and challenge were shoulder tip pain 35(18.0%) and instrument failure 76 (39.2%), respectively. There is a statistically significant relationship between the occurrence of complications during Endoscopy and duration of surgery (X2 = 25.693, P= 0.000), endoscopy type (X2=21.636, P=0.000), and hospital stay (X2 = 63.213, P=0.000) Conclusion: The utilization rate of gynaecological pan-endoscopy could be higher and shows more skills, logistics, and staffing. Therefore, efforts should be intensified towards training and provision of up-to-date facilities for endoscopic surgery in our setting.
Does Innovation Ambidexterity Moderate the Relationship between Intellectual Capital and Innovation Performance? Evidence from Morocco 


Innovation performance is seen as the backbone of firm ’s sustained competitive advantages. Scholars of the dynamic capability view suggest that Intellectual Capital (IC), such as human, structural, and relational capital, are the main driving force of a firm’s Innovation P erformance (IP). The purpose of this study is to investigate the importance of developing firms’ intellectual capital and their role in leveling up innovation performance. In doing so, this paper conducts an examination by moderating the variable of Innovation Ambidexterity (IA), namely explorative and exploitative activities. By applying a quantitative and cross-sectional design, the study deploys data feedback from managers and executives of manufacturing SMEs across the Moroccan national territory collected from 286 surveys. The results show that IC has a positive and significant impact on IP, while IA has a positive and significant effect on both IP and IC. The study also finds that IA failed to moderate the relationship between IC and IP. This study contributes to advancing the capability theory by adding the importance of developing and reconfiguring firm ’ s human, structural, and relational capital as the main driving force of innovation performance.
Islam and Traditional Fabrics: Symbolic Da’wah in Sambas Malay Weaving Motifs, West Kalimantan

This article aims to analyze symbolic da'wah through the weaving motifs of Malay Sambas, West Kalimantan. This study uses an interpretive paradigm with a semiotic method. The data sources in this study were 22 motifs of Sambas Malay woven fabric. Data was obtained through observation and interviews. The data obtained were then analyzed using the semiotic triangle meaning model of Charles Sander Peirce. This study finds that the woven fabric motif is formed through a long process and closely relates to the socio-cultural construction of the Sambas Malay society. At this level, the Sambas Malay weaving motif is created from three elements: beauty, cultural identity, and the ethnoreligious reality of the Sambas Malay society, and efforts to internalize Islamic teachings in Sambas Malay life through the meaning and symbolic message of the motif. Based on these findings, it can be concluded that the Sambas Malay weaving motif is not only a cultural product of the Sambas Malay society but also a symbolic da’wah medium in the Sambas Malay society through a cultural approach.
Gender differences in epidemiology and risk factors of acute coronary syndrome in Algerian patients of the Oran city: descriptive cross-sectional study

Background and aims: The aim of this study is to determine the role of clinical, lifestyle, and behavioral characteristics on the severity of the disease according to the gender. Methods: We conducted a cross-sectional descriptive study. Results: An initial sample of 1219 patients was admitted for ACS in the cardiology service of Oran-Univer-sity-Hospital-Center. The electrocardiographic results revealed that 34% of the patients had ST-segment elevation myocardial infarction (STEMI) while 66% had non-ST-segment elevation myocardial infarction (NSTEMI). In STEMI patients, the mean age was 60.87±12.20 years. STEMI patients sample included 413 pa- tients with 324 men with a mean age of 59.92±11.78 years and 89 women with a mean age of 64.36±13.13 years. A male predominance observed with a sex-ratio of 3.6. Among STEMI patients, 34.8% of patients had hypertension where it was signiﬁ cantly higher in women than in men (65.6% vs 26.5% respectively, p < 0.05). Diabetes was observed in 31.7% of the whole sample where it was also more common in women compared to men (50.6% vs 26.5%, respectively, p <0.05). Out of the 413 STEMI patients 63.9% had dyslipidemia which was signiﬁ cantly higher in men compared to women (76.5% vs 13.5% respectively, p <0.05), 64.5% of men were current smokers. Out of the 324 STEMI men patients, 46.5% had three risk factors while in the 89 STEMI women patients, 34.8% had four risk factors. Conclusion: Our results demonstrated a higher prevalence of ACS among the studied sample. STEMI patients presented with several cardiovascular risk factors. Sex differences in the ACS presentation and risk factors was also noticed.
Improved TEC retrieval based on spaceborne PolSAR data

It is well known that for Earth observations, the spaceborne synthetic aperture radar (SAR) systems at L‐band can be seriously affected by the ionosphere. Fortunately, the destructive ionospheric information, total electron content (TEC), can be retrieved and removed by model inversion from SAR echoes and becomes a subject of interest for ionospheric research. Considering the system noise and channel phase imbalance, this paper focuses on accurate TEC retrieval from the Faraday rotation angle, which is embedded in Advanced Land Observing Satellite phased array L‐band synthetic aperture radar (PALSAR) full‐pol data. For the consideration of denoising, averaging filtering is widely used in existing studies to remove the system noise. In order to further reduce the noise effects, a fast total variation (FTV) denoising method is applied in this paper. By using the PALSAR full‐pol data sets, a series of simulation results show that the FTV denoising is effective for noise suppression and markedly reduce the standard deviation. For the error of channel phase imbalance, a new Faraday estimator based on the covariance matrix of circular basis is proposed. Compared with previous estimators, theoretical analysis and simulation results show that this new estimator can give the best performance for sensors that are dominated by channel phase imbalance errors. Thus, the proposed estimator can be a candidate method for TEC retrieval when phase imbalance is the domain error.
State Estimation Under Sparse Sensor Attacks: A Constrained Set Partitioning Approach

State estimation from the sparsely corrupted measurements, a combinatorial problem, has been addressed by brute force search or convex relaxations in the literature. However, the computational efficiency and estimation correctness of these methods cannot be simultaneously guaranteed. This paper studies how to relieve the computational complexity on the premise of the estimation correctness. A novel algorithm based on a constrained set partitioning approach is presented. The computational efforts are alleviated by drastically reducing the search space, and the estimation correctness is guaranteed in terms of the existence of a solution for a set of linear matrix inequalities. The theoretical results are substantiated by simulating two numerical examples.
DARCY EQUATION FOR RANDOM POROUS MEDIA

Many attempts have been made recently to deduce Darcy equations for flows through porous media. Much has been done for models having a periodic microstructure. This paper presents a mathematical analysis based on the more general and more realistic assumption that the microstructure of porous media is random and stochastically homogeneous. For this type of random domain we consider homogenization of the Poisson and Stokes equations supplemented by homogeneous Dirichlet boundary conditions on the random boundary. With this approach we get the Darcy equation in general as well as present details for the particular case of a checkerboard model of porous media. © 1996 John Wiley & Sons, Inc.
A nonparametric procedure for testing partially ranked data

ABSTRACT In consumer preference studies, it is common to seek a complete ranking of a variety of, say N, alternatives or treatments. Unfortunately, as N increases, it becomes progressively more confusing and undesirable for respondents to rank all N alternatives simultaneously. Moreover, the investigators may only be interested in consumers’ top few choices. Therefore, it is desirable to accommodate the setting where each survey respondent ranks only her/his most preferred k (k < N) alternatives. In this paper, we propose a simple procedure to test the independence of N alternatives and the top-k ranks, such that the value of k can be predetermined before securing a set of partially ranked data or be at the discretion of the investigator in the presence of complete ranking data. The asymptotic distribution of the proposed test under root-n local alternatives is established. We demonstrate our procedure with two real data sets.
FMCW Radar for Noncontact Bridge Structure Displacement Estimation

The displacement on the bridge structure is an essential parameter in identifying the bridge structure’s health. The noncontact measurement method is preferable in practice, and the radar system is potentially employed for developing displacement measurement technology. Frequency-modulated continuous wave (FMCW) radar has a feature for detecting the target location. However, estimating the small displacement in the bridge structure requires extensive bandwidth to reach the proper resolution. The problem of obtaining the required resolution, and adopting the decrease in accuracy due to several possible radar placements during measurement are addressed in this article. The concept of bridge displacement measurement using a modified FMCW radar system is proposed. Phase information extraction is employed to reach the displacement detection resolution, and the radar elevation detection based on an inclinometer is equipped in the proposed radar system. The simulation and laboratory experiments were conducted by implementing the proposed radar system for detecting the displacement in the bridge model. The experiment results confirm that the proposed FMCW radar was able to estimate the bridge displacement and overcome the decreasing accuracy due to the radar elevation. The multipoint detection technique is also developed in the proposed radar and is capable to capture the displacement profile over the bridge span. The proposed FMCW system is then recommended as a radar system in developing a noncontact method for bridge displacement measurement and monitoring.
