28 GHz Patch Antenna Array with Reduced Mutual Coupling for 5G Communications Systems
Authors: Mwang’amba Rahabu , Iddi Hashimu
Published: August 2022

A 28 GHz patch antenna array with reduced mutual coupling for 5G communication systems is presented in this paper. Two elements antenna array was simulated with a periodic boundary to represent an infinity array. The antenna array is attached with a pair of the coupled directional coupler with a coupling value of -3.47 dB, and transmission lengths of 3.40 mm and 7.62 mm depending on the antenna array's magnitude and phase coefficient were designed and simulated. A reduced mutual coupling of -31.86 dB compared to -10.75 dB for an array without a decoupling network was observed. The wide scanning angle of ±180o was also achieved. These results were obtained under smaller antenna elements interspacing of 0.43 0. Moreover, the proposed antenna array design achieved a 3.32 GHz enhanced fractional bandwidth which is 11.8%. Generally, this work found that the combinatorial advantages of using the gap coupled insert feed technique and employing a pair of directional couplers develop the patch antenna array design with better performance.

Published: August 2022

This study aims at providing an experimental sizing procedure for a rooftop PV-based solar power system for an engineering laboratory. This was achieved by monitoring the peak power and energy delivered by an installed 20W solar panel into an 18 Ah battery. Knowledge of the average daily peak power and energy was used to determine the percentage rated capacity available for use and the sun hour. A load consumption comparison was also carried out with and without the connection of a load to inverter. In addition to this, the monitoring of the no-load consumption of the inverter was carried out. This was carried-out to ascertain the contribution of the inverter to the system. With the knowledge of the average daily energy deliverable, sun hour and the no-load power of the inverter, a sample sizing for basic electronic laboratory loads was done. The findings of the study reveals that the average available power is 89.35% of the solar panel rated capacity while the average sun hour is 4.38 h. It has also been shown that an approximate difference of 20 W exists between the power consumption of the load with and without its connection to the inverter. This value (i.e., 20W) has been recorded as the approximate no-load power for the inverter. The sample sizing done has shown that, the solar panel energy requirement of the system with inverter may be considerably higher than that without inverter.
In-situ Observation of Retained Austenite and Residual Stress Evolutions during Tempering of carbonitrided DIN 1.6587 Alloy Steel
Authors: Katemi Richard , Epp Jérémy
Published: August 2022

This paper investigates the evolution of retained austenite and residual stresses during and after tempering of carbonitrided 18CrNiMo7-6 low alloy steel carried out using in-situ X-ray diffraction technique. In this case, two carbonitriding treatments with different surface the retained austenite contents of 20 and 54 mass.-% are investigated. The tempering is carried out in a continuous heating mode to 650°C as well as in isothermal mode at holding temperature of 170, 240, and 300°C for 2 hours. During continuous heating at a heating rate of 10°C/min, the retained austenite started to decompose at 290°C. On isothermal holding at 170°C for 2 hours, the retained austenite remained relatively stable at 20 and 54 mass.-% while readily decomposed to less than 5 mass-% on holding at 300°C. On continuous heating, residual stress in martensite continuously relaxes and reaches full relaxation (0 MPa) at about 400°C. During isothermal holding, residual stresses in martensite are increasingly relaxed with increasing holding tempering. Further relaxation of residual stresses is observed during cooling whereas a cyclic variation of the residual stresses in the retained austenite could be determined.

Modelling Monthly Rainfall of Calabar, Nigeria Using Box-Jenkins (ARIMA) Method
Authors: Ogbozige Francis
Published: August 2022

Rainfall has both positive and negative effects on human activities hence, correct prediction of the period of occurrence is very essential. However, the traditional method of predicting months of heavy rainfall is gradually fading out as irregular rainfall pattern is been experienced in most regions of the world. The rainfall pattern in Calabar city in Southern Nigeria has been reported in past literatures of being irregular. Hence, this research applied the Auto-Regressive Integrated Moving Average (ARIMA) also known as Box-Jenkins method to model the rainfall pattern of Calabar. This was achieved by subjecting 50years monthly rainfall (1971 – 2020) to gretl software version 2021b. The analysed data showed that the rainfall of the study area required just one-time differencing to attain stationarity at 95% confidence, while the order of the Auto-Regressive AR(p) and Moving Average MA(q) models were either 1 or 2 in both cases. Hence ARIMA(1,1,1), ARIMA(1,1,2), ARIMA(2,1,1) and ARIMA(2,1,2) were identified and further analyses revealed that ARIMA(2,1,2) best suited the rainfall of the study area. A diagnostic check was carried out on the selected ARIMA (2,1,2) model and it was observed to be reliable (minimal white noise) thereafter, it was used to forecast the rainfall of the study area for some months.
Analyzing the Influence of Smart-device Visual Features, Viewing Distance, and Content Factors on Video Streaming QoE
Authors: Mongi Alex
Published: August 2022

Quality of experience (QoE) over wireless networks has attracted attention from industry and academia due to an increase in video streaming applications. Several researchers have attempted to understand the factors affecting QoE and design appropriate quality control strategies. Normally, video streaming is initiated by a user who accesses video contents over wireless networks using a smart device held at various viewing distances. Each aforementioned factor has the potential to affect QoE of the viewed session. However, several studies explore the behavior of wireless networks on video streaming QoE. To understand the effects of other factors on QoE, this paper investigates the influence of the device's visual features, viewing distance, and content factors on video streaming. The study adopted an emulation technique to conduct multi-factor experiments designed using the Taguchi method. The 5-ways ANOVA analysis revealed that the effects of smart-device visual features, viewing distance, and content types are significant on video streaming QoE at p<0.05. Moreover, smart devices with a pixel density index of more than 200 ppi produce high QoE, with the viewing distance limited to 45 cm. Lastly, the video bitrate greater than 1024 kbps produced a good QoE regardless of the frame rates.

Published: August 2022

ABSTRACTThe study investigated the effect of testwiseness on academic performance of Senior Secondary School students in Economics in Oyo State, Nigeria.The study employed quasi-experimental pre-test and post-test two group design. The population for the study comprised all the public Senior Secondary School Two (SSS2) students offering Economics in Oyo State, Nigeria. The sample for the study consisted of 240 senior secondary school Two (SSS2) students using multistage sampling procedure. The instrument for the study were Economics Achievement Test (EAT) and Testwiseness Questionnaire (TQ). Face and content validity of the instrument were established by expert judgment. The reliability coefficient of EAT was estimated using test re-test reliability method while the reliability coefficient of TQ was estimated using Cronbach Alpha reliability method. The reliability coefficients of EAT and TQ were 0.79 and 0.82 respectively. The data collected were analysed using both descriptive and inferential statistics. The research questions raised were answered using mean and standard deviation and bar chart while the hypotheses formulated were tested using Student’s t -test and Analysis of Covariance (ANCOVA) at 0.05 level of significance. Results of the study showed that there was significant difference in the performance of students exposed to testwisness strategy and those in control group. Also, the results showed that there was no significant effect of the testwisness strategy on the performance of the students based on gender and school location. It was, therefore, concluded that students with testwiseness strategy perform better than those without testwiseness strategy and that gender and school location have no significant interactive effect on students’ achievement in Economics when exposed to testwiseness strategy.It was recommended that students should be exposed to testwiseness strategy to improve their performance in Economics irrespective of their gender and school location.
The Development of a Self-Regulated Second Language Learning Questionnaire for an L2 Self-Study Setting
Authors: Fukuda Akiko
Published: August 2022

This study developed a Self-Regulated Second Language Self-Study Questionnaire that addresses the self-regulated learning (SRL) skills of learners of English as a foreign language in a self-study setting. Much attention has been paid to SRL in second language acquisition; however, contexts outside school have hardly been explored. To address this issue, based on the Motivated Strategies for Learning Questionnaire, a new questionnaire was created and applied to a sample of 112 Japanese university students. The exploratory factor analyses extracted three factors (i.e., self-efficacy, learner values, and test anxiety) from the motivation section of the questionnaire. Additionally, four factors (i.e., metacognitive strategies, problem solving, learning maintenance, and learning effort) were extracted from the learning strategy section. All seven factors showed adequate internal reliability. Additional confirmatory factor analyses demonstrated sufficient model fit indices for construct validity, whereas some were disputable.
Accent Anxiety: An Exploration of Non-Native Accent as a Source of Speaking Anxiety among English as a Foreign Language (EFL) Students
Authors: Coppinger Lucy , Sheridan Sarah
Published: August 2022

Speaking anxiety is a form of foreign language anxiety which may reduce students’ willingness to communicate orally. Despite accent being one of the most salient aspects of speech, there has been little research to date on the relationship between non-native accent and speaking anxiety. The purpose of this study is therefore to examine English learners’ perceptions and beliefs about accent, and also to explore the concept of accent anxiety, that is, speaking anxiety arising due to concern about one’s non-native accent. An anonymous online questionnaire was distributed to English students in a French university. The questionnaire sought to gauge the students’ attitudes both towards speaking and accent and gathered qualitative responses about the students’ experiences of accent anxiety and their coping strategies. A thematic analysis was then carried out on the 54 responses. It was found that the majority of the students did not believe attaining a native-sounding accent was essential to language learning and felt that comprehensibility should be the primary objective. However, many of these students nonetheless considered it a personal goal to sound more native-like. Furthermore, most of the students had at some point in their learning felt embarrassed or worried about their accents, with the two primary causes being fear of negative evaluation from their peers and fear of future communication issues. It was concluded that concern over how non-native accents sound is a potential source of speaking anxiety for learners of English. As these students highlighted the classroom as being the main location where this anxiety arises, the study concludes with some suggestions for educators as well as ideas for future research directions.
A Per-second Investigation of the Interconnectedness between Linguistic and Cognitive Factors Underlying L2 Willingness to Communicate
Authors: Nematizadeh Shahin
Published: August 2022

Willingness to communicate (WTC) research has recently witnessed a paradigm shift with the more recent studies looking at the shifting and dynamic nature of the variable. A growing body of literature has interpreted such dynamicity from a complex dynamic systems (CDS) perspective. The theory of CDS has four basic properties, one of which, and the focus of this study, is the interconnectedness among subsystems. This property mainly involves the interplay amongst parts of a system, which interact and influence one another, determining the subsequent dynamics in the system. This qualitative, exploratory study employed an idiodynamic method to investigate the interconnectedness of the cognitive and linguistic factors underlying second language (L2) WTC. To this end, 20 participants completed four three-minute monologic speaking tasks while being video-recorded. Immediately after, they viewed their recordings, rated their WTC moment by moment, and explained the WTC changes in stimulated recall interviews. The interviews were coded, and instances where WTC was affected by cognitive and linguistic factors were identified and analysed. Three patterns of interconnectedness emerged: (1) WTC and linguistic factors; (2) WTC and cognitive factors; and (3) WTC, and linguistic and cognitive factors. Findings provide a clearer account of the interconnectedness property in the WTC system, lending support to viewing WTC as a CDS. The article highlights the importance of self-perception and availability of content message, in addition to the above factors, and concludes with a brief discussion of the pedagogical implications for L2 classroom.

Published: August 2022

Abstract

This study aims at earmarking some related issues regarding the teaching of English language to francophone pupils by francophone teachers. As regard the theoretical framework, the connectionism, acculturation and teaching-learning theories was used.  The methodology in this study is the quantitative and qualitative approach and the random sampling technique is used in the selection of the population under study.  The research instruments that are used are the interview and observation.  The instruments were administered taking into consideration the pronunciation of sounds (phonology) pluralisation of nouns, sentence construction, the use of articles and tenses (morpho-syntax).  A total of 73 teachers from six primary schools were interviewed and observed.  The frequency distribution technique is used for analyzing data. Analyzing the data collected proves that the francophone teachers have difficulties in pronouncing some sounds in the English language.  The teachers equally have difficulties in putting some nouns in their plural forms, constructing of sentences and correct use of articles and tenses. From the findings, the researcher made some recommendations.  That a solid foundation should be laid during the initial training on the teaching of the English language. Secondly, in-service training should be encouraged for  teachers already in the field. The researcher also suggested that Pedagogic Inspectors in charge of bilingualism should organize regular pedagogic seminar on English language for the francophone teachers.

Published: August 2022

Investigation of groundwater contamination from an active landfill was carried out in Saje, Abeokuta Ogun state, Nigeria using geophysical and geochemical methods. Four resistivity traverses picked up within the landfill. Wenner array electrode configuration was adopted and the data
were interpreted using RES2DINV program. Quantitative valuations were accomplished by geochemical and hydrogeochemical facies of groundwater samples collected from ten dug wells in the arcade of Saje landfill. Fifteen parameters were analysed in the groundwater samples. The results of the
2D resistivity analysis showed that there is a constant and progressive increase in the depth of migration of the contaminants generated from this landfill site into the subsurface environment as its ages. The results of both physical and chemical parameters of the water analysis revealed
that all the parameters were 100% in compliance with the World Health Organization (WHO) and Nigerian Standard of Drinking Water Quality (NSDWQ) standard permissible limits for drinking, water except for pH (90%), Calcium (80%) and Lead (80%). The classification of water samples of the study
area using Piper Trilinear diagram revealed that 70% of the analysed water samples are of CaHCO3 (fresh water) type, 20% are of CaCl2 type and 10% are CaMgCl type. The calculated values of irrigation parameters such as; Magnesium Absorption Ratio, Sodium Absorption Ratio,
Total dissolve solid, Soluble Sodium Percentage, Kelly's Ratio and Permeability Index for most of the groundwater samples were found to be suitable for irrigation. The groundwater quality index evaluation acquired for the study area ranges from 3.8 – 18.1. This study established that
the groundwater around this region is 100% suitable for drinking purposes.

Published: August 2022

Landfill site selection is a multi-criteria decision problem and has strategic value for various countries. The conventional method for landfill site selection is not enough to address the vague nature of linguistic assessment. An integrated Fuzzy AHP method was used to resolve this
issue. Suitability maps produced by conventional Analytical Hierarchy Process (AHP) and integrated Fuzzy AHP methods were compared and validated, which adds a new dimension in the waste management field. Various environmental, socio-economic, and infrastructure factors were used as predictors,
which included groundwater level, soil type, slope, land cover, distance to settlements, railways, roads, surface water sources, airport, power lines, wells, and protected areas. Relative Operation Characteristic (ROC) analyses gave results of 0.77 and 0.86 for the suitability maps of AHP
and Fuzzy AHP, respectively. The landfill site suitability maps produced from this study could help urban planners, engineers, decision-makers, and land-use developers to make suitable decisions. Furthermore, the resulted integrated model showed the best suitability that could be implemented
to resolve the fundamental landfill siting problems in other cities of Pakistan.

Shaping English Language Policies in Academia: Female Saudi English as a Foreign Language Learners’ Perspectives
Authors: Almohaimeed Nura , Nasser Alnasser Suliman Mohammed
Published: August 2022

English in Saudi Arabia is an English as a Foreign Language (EFL) context which offers very limited opportunities for language practice. The literature suggests that English education in Saudi higher education suffers from weaknesses in English language learning outcomes, leading researchers to explore ways to mitigate this concern. Hence, English language policies (ELPs) can play a significant role in compensating for the lack of limited language practice opportunities outside the classroom and within academic settings. Therefore, this study addresses the necessity of introducing ELPs in academia from learners’ perspectives. A mixed method approach was employed to collect data using an online survey (n = 257) and semi-structured interviews (n = 10). The participants were female Saudi EFL learners undertaking undergraduate and post-graduate academic programs in Saudi higher education English departments. The main findings of the study suggest that ELPs do not exist in these departments, and that students are highly motivated to engage in designing these policies. The implications of this study are also discussed.

Medicinal plants have shown to possess some biologically active constituents that have significant effects in human. This study was carried out to evaluate the effect of Goko Cleanser (herbal mixture) on the kidney of albino Wistar rats. Phytochemical analysis of the herbal mixture was done. A total of twenty-five animals weighing 150 g – 200 g were used. The rats were randomly selected into five groups of five (5) experimental rats. The groups were classified as A-E, and graded dosage of the herbal mixture administration was done. Group A served as normal control group and received no herbal mixture, group B received 1000 mg/kg of the herbal mixture, group C received 2000 mg/kg of the herbal mixture, group D received 3000 mg/kg and group E received 4000 mg/kg. The results show that Goko Cleanser herbal mixture contains tannin, saponin and flavonoids as its phytochemical constituents. The creatinine level had a significant (P<0.05) increase in test groups D and E when compared to the control group; while in groups B and C, there was no significant increase (P>0.05) when compared to the control group. The urea and potassium levels also had significant increases (P>0.05) in the test groups D and E when compared to the control group. Results of histopathological analysis showed a concomitance with the biochemical findings. Hence, the results from this study show that Goko Cleanser herbal mixture possesses dose-dependent toxic effect on the kidney.

Although many vaccines are in development and clinical trials, and many vaccines have been distributed worldwide, the world has faced a huge challenge in line with the willingness to accept a COVID-19 vaccine in different countries. However, no study has been conducted on the acceptance of the COVID-19 vaccine among HCPs in Iraq. Therefore. Health care providers, the frontline fighters, are at high risk of being infected with SARS-CoV- 2.  A descriptive; the cross-sectional study was performed at 4 hospitals and 18 PHCCs randomly selected (multistage sampling) in the   Karbala governorate. The period of data collection lasted 3 months, it began on 18th January 2022 ending on 12th April 2022. The study was conducted on 457 a sample of health care providers. The study conducted on 457 healthcare providers with an age range was between 20 -59 years, the Mean±SD of the age was 33.6±9.42 the highest percentage of healthcare providers (45.3%) was in the age group 20-29 years and the lowest percentage of healthcare providers (8.8%) was in the age group 50-59 years.

Pomegranate fruit is edible and has been used on leukemia cell lines and protecting DNA damage known antioxidant efficacy the aim of the current work is to explore the potential benefit of pomegranate (Punica granatum) extract as antioxidant and cytotoxic to leukemia cell line. Methanol was used to extract pomegranate fruit so that to test its antioxidant and cytotoxicity on two cell lines (Hepatic cell line WRL68 and Leukemia cell line HL60). This assay was classified as determining antioxidant effect using 3-(4,5-dimethylthiazol-2yl) 2,5diphenyl tetrazolium (MTT) assay on two cell lines (Hepatic cell line WRL68 and Leukemia cell line HL60) for different concentrations (25, 50, 100, 200 and 400 µg mL-1). These examine the efficacy of the phenol extract on HL60 cell apoptosis, morphology, viability of cells, total nuclear intensity, cell membrane potential, mitochondrial membrane potential, and cytochrome C release were evaluated by High Content Screening (HCS) assay. The current results revealed that the methanol extract of pomegranate fruit had the strongest antioxidant activity, which increased when concentrations were raised (28.27 and 61.57%). The results demonstrated that phenol can inhibit HL60 cell line from growing, with increased concentrations. The inhibition become stronger at 400 µg mL-1 of phenol extract.

Introduction: Autoimmune hepatitis (AIH) is one of autoimmune disorder with complex pathophysiology. Many genes involved in lethal autoimmune hepatitis disorder including STAT4 gene. The aim of this study is to determine STAT4 gene polymorphisms and relation of SNPs with disease severity among AIH patients. Method: One hundred AIH patient which diagnosed by clinically, ANA and ASMA and 100 control age matched healthy children were enrolled in this study. Patients' blood samples (5mL) were taken and split into two tubes, one tube used for immunological and clinical parameters and the second containing EDTA for PCR analysis. The first tubes were then left at room temperature for 10 minutes before being centrifuged (3500 rpm). After that, the serum was isolated the both tubes stored at -70°C until analysis, biochemical parameters were measured in full automated biochemistry analyzer while, IgG, ANA and ASMA was investigated using the enzyme-linked immunosorbent assay (ELISA) commercially available kits (Bioneer, Korea), while the STAT4 (rs7574865, rs7582694) gene was investigated using RFLP PCR How, and the commercially available kits (Bioneer, Korea).

This study was designed to investigate the effect of addition several concentrations of royal jelly to the media used in the in vitro maturation process of Iraqi sheep. The ovary was brought from the Al-Shulla slaughterhouse and transferred to the obstetric laboratory at the College of Veterinary Medicine at the University of Baghdad by a thermal insulating box containing the physiological solution with the antibiotic penicillin at a temperature of 30-38°C. In the laboratory, the ovaries were washed with a neutral buffer solution and then the oocytes were collected by two different methods slicing ovaryor follicle aspiration. The oocytes were classification into four groups depending on the layers of the cumulus cells surrounding the oocytes, as well as the homogenous of the cytoplasm. Oocytes that are completely or partially surrounded by cumulus cells and homogeneous cytoplasm considered normal oocytes but the oocytes denuded from the cumulus cells and heterogeneous cytoplasm considered abnormal oocytes was discarded. Normal oocytes were divided randomly into four groups at maturation; the first group was matured by TCM media alone and was considered as a control group.

Spirulinal powder supplementation is being studied to see if it can help slow the progression of aging in the heart. As a control group, twenty male rabbits were randomly and equally divided into four groups, each receiving 150 mg/kg BW of d-galactose S/C daily as Group II; 500 mg/kg BW of Spirulinal orally as Group III; and 150 mg/kg BW daily S/C administration of d-galactose with 500 mg/kg BW orally as Group IV for four weeks. Using the specific stain Masson's Trichrome, stained sections of the aorta from the D-gal group (GII) and the combination group (CII) exhibit histological changes in the tissue (GIV). Tissue slices stained with Masson's Trichrome stain reveal the location of collagen and muscle fiber accumulation, which appears as a red keratin and muscle fiber accumulation area. Our findings show that Spirulinal powder, a feed supplement, has a protective effect against heart aging.

The work is based on the results of treatment of 233 patients with femoral injuries in concomitant trauma. Males predominated 65.4%. As a result of a road traffic accident, 61.4% of the victims were injured. The most common combination was a concomitant craniocerebral injury, and a fracture of the femur - 42.5%, multiple fractures of the limbs - 16.3% and with polytrauma - 15.0%. In 76.8% of cases, at the time of hospitalization, the condition of patients (ISS: 11.7–22.8). In 202 patients, in 88.7% of cases, in the treatment of femoral fractures, a surgical method was used - osteosynthesis. We have developed a tactic for the treatment of hip injuries, which was based on the severity of the condition and the severity of the injury. It was fundamental that all hip fractures should be stabilized using surgical methods in the early period of traumatic disease. Surgical interventions should be performed after the elimination of the dominant pathology, or after stabilization of hemodynamics.
