Published: August 2022

Background:

The aim of the present study was to detect the prevalence of accidental pathological findings in asymptomatic maxillary sinuses in patients referred for head and neck cone-beam computed tomography (CBCT) examination for varied reasons.

Methods:

The present cross-sectional study included a detailed analysis of CBCT scans of 150 patients aged between 18 and 70 years reporting for varied dental complaints for detecting accidental pathological findings in maxillary sinuses while the patients did not have any complaint pertaining to sinuses.

Results:

The findings of the present study revealed 58% patients to have pathological findings in maxillary sinuses while they were asymptomatic for sinuses. Furthermore, the prevalence of mucosal thickening was found in 29.3% of the patients while 36.7% patients presented with polypoidal mucosal thickening.

Conclusion:

Higher prevalence of pathologies in asymptomatic maxillary sinuses found in the present study emphasized significance of a thorough examination of routine dental patients by dento-maxillofacial radiologists with necessary investigations to be advised in the form of higher imaging modalities like CBCT, if necessary.

Authors: Das Debasish , Das Tutan , Pramanik Subhas
Published: August 2022

We report an extremely rare association of left-sided inferior vena cava (IVC) in a 38-year-old female presenting with recurrent palpitation for the past 2 years with typical slow-fast atrioventricular reentrant tachycardia (AVNRT). We delineated the course of the left-sided IVC with pigtail injection and catheter course to the right atrium and successfully modified the slow pathway with conventional catheters with difficulty in ablation catheter maneuvering and his catheter stability was an issue. Our case is the first description of an unusual association of isolated left-sided IVC in a patient with typical AVNRT.
A Rare Case of Premature and Parallel Posterior Descending Artery and Posterior Left Ventricular Branch with Conus Crossing the Right Ventricular Outflow Tract Causing Provocative Coronary Ischemia
Authors: Das Debasish , Das Tutan , Singh Shashikant , Gupta Jaideep Das , Pramanik Subhas
Published: August 2022

We report a rarely encountered case of premature and parallel posterior descending artery (PDA) and posterior left ventricular branch (PLVB) in a case of 22-year-old male with effort angina Class II for the last 6 months in whom treadmill test (TMT) was strongly positive for provocative coronary ischemia with structurally normal heart and good biventricular function. Interestingly, all the coronaries were normal without any obstructive coronary lesion. Paradoxically, those two prematurely separating branches were small making the distal right coronary artery (RCA) territory relatively ischemic attributing toward a strongly positive TMT. Small anomalous coronary is a well-known cause of demand ischemia, but our case is unique to describe small prematurely originating PDA and PLVB were the culprit behind coronary ischemia in a young male without conventional risk factors. Furthermore, much premature separation of PDA and PLVB is rarely encountered in routine clinical practice, and recognition of this anomaly is important as it should not be mistaken for duplicate RCA, dual RCA, or split RCA. Our case is also unique to illustrate the association of the premature and parallel PDA and PLVB with a conus crossing the right ventricular outflow tract without the presence of structural heart disease.

Authors: Soyebi Kofo O. , Agboola Ajibola S. , Oyeleke Ganiyat K.
Published: August 2022

Background:

Delayed intervention in chronic viral hepatitis results in progression to fibrosis and hepatocellular carcinoma. Determining the degree of liver fibrosis is invaluable in the initiation of clinical interventions, prevention of progression, and prognostication of end-stage liver disease. Considering the risks of liver biopsy (the standard for assessing fibrosis), safer methods are necessitated.

Aim:

The aim of this study was to determine the reliability of ultrasonographic Portal Venous Index (PVI) in assessing liver fibrosis.

Subjects and Methods:

Doppler Ultrasonography-determined Aspartate-Platelet Ratio Index (APRI) Score.

Results:

The mean age for the subjects was 35.79 ± 10.75 years and controls was 36.51 ± 11.31 years. They were sex matched. HBV was more common, with a 99:3 HBV: HCV ratio. HBV immunization compliance in both the groups was poor. The median PVI of the subjects and controls was 0.36 and 0.42, respectively, which was statistically significant (P = 0.025). There was no significant difference in median PVI between subjects with and without significant fibrosis as determined by APRI score. There was an inverse but moderate correlation between PVI and APRI score (r = −0.57, P= 0.569). The area under the receiver operating characteristic curve was 0.524 (95% confidence interval: 0.36–0.69). The cutoff for PVI was 0.34 with a sensitivity of 57.1% and a specificity of 57.4%.

Conclusion:

PVI is useful in distinguishing healthy individuals from virus-induced chronic liver diseases but could not adequately determine the degree of liver fibrosis.

Published: August 2022

Background:

Computed tomography (CT) of the chest is a useful diagnostic adjunct in the management of COVID-19. It has proven useful in areas where ready access to real-time reverse transcriptase polymerase chain reaction (PCR) is not readily available.

Objectives:

This study sought to evaluate the chest CT findings of patients suspected with having COVID-19 on presenting at the emergency room.

Materials and Methods:

This is a retrospective study done in Cedarcrest Hospitals, Abuja, with patient information pooled from patients' electronic medical records from April to December 2020. Patients were selected based on suspicion of COVID-19 infection. Suspicion was stratified into high, moderate, and low using an in-house clinical suspicion score called the Cedarcrest Emergency COVID-19 Risk Assessment Tool. Patients with background pulmonary pathology or chest trauma were excluded. Plain chest CT scans were performed to evaluate for COVID-19 pneumonia.

Results:

CT imaging increased the clinical suspicion of COVID-19. However, no statistically significant relationship was found between the positive CT findings and the PCR results.

Conclusion:

Chest CT should be correlated with clinical findings and laboratory results for patient evaluation.

Authors: Dahiru Abdullahi , Adamu Yahuza Mansur , Isyaku Kabiru , Ismail Anas , Lawal Yusuf , Yusuf Murtala
Published: August 2022

Background:

Hypertension is one of the leading causes of maternal and fetal mortality and morbidity. The middle cerebral artery (MCA) is the major supplier of blood to the brain. Doppler velocimetry has made it possible to identify and insonate the fetal MCA and is used in fetal surveillance in high-risk pregnancies and has been efficacious in antenatal fetal monitoring.

Materials and Methods:

Sixty-five patients with hypertensive disorders of pregnancy and 65 normotensive pregnant controls between 20 and 39 weeks of gestational age were recruited for this study. Obstetric ultrasound scan was done to determine the gestational age, estimated fetal weight, and amniotic fluid indices. Fetal MCA Doppler velocimetric indices (peak systolic velocity [PSV], end-diastolic velocity [EDV], (RI) Resistivity index RI-resistivity index, pulsatility index [PI], and systolic/diastolic ratio [S/D ratio]) were also measured and documented.

Results:

The mean PSV of the study group (32.1 ± 10.1 cm/s) was lower than that of the control group (38.6 ± 9.3 cm/s). This difference was not statistically significant (P = 0.416). However, the mean EDV of the study group (9.09 ± 2.9 cm/s) was higher than that of the control group (8.6 ± 2.0 cm/s) which was also not statistically significant (P = 0.074). There was a statistically significant difference (P ≤ 0.001) between the mean RI of the study group (0.70 ± 0.10) and that of the control group (0.77 ± 0.05). The mean PI of the study group (1.35 ± 0.5) was also lower than that of the control group (1.49 ± 0.3), which was statistically significant (P ≤ 0.001). There was also a statistically significant difference (P = 0.003) between the mean S/D ratio of the study group (3.64 ± 1.4) and that of the control group (4.5 ± 1.1).

Conclusion:

There was a significant statistical difference in the fetal MCA Doppler velocimetric indices between hypertensive and normotensive groups indicating that fetal MCA Doppler ultrasound is a useful tool in monitoring the hemodynamic changes in the cerebral circulation of fetuses of mothers with hypertension in pregnancy.

Published: August 2022

Purpose:

The purpose of this study was to investigate if the renal arterial resistive index (RRI) is impaired in women with breast cancer and correlate these values with estimated glomerular filtration rate (eGFR) as determined by the Chronic Kidney Disease Epidemiology Collaboration equation.

Materials and Methods:

This was an observational study of fifty chemotherapy-naïve women with histologically confirmed breast carcinoma recruited consecutively over a 1-year period. All women had a Doppler ultrasonography done to determine their RRI and eGFR.

Results:

Fifty women with breast cancer were evaluated. Their ages ranged from 28 to 85 years, with a mean age of 48.6 ± 13.8 years. The mean RRI in the study was 0.7 ± 0.07. There were thirty subjects (60%) with abnormal resistive index (RI) (>0.7), whereas twenty subjects (40%) had normal RRI. The mean eGFR in the study cohort was 62.6 ± 17. eGFR was abnormal in 96% of the women. About half (n = 24, 48%) had severe renal insufficiency (stages 3 and 4). The majority had advanced breast disease (stages 3 and 4), with 23 patients (46%) presenting with stage 3 disease and 17 (34%) stage 4 disease. Pearson's correlation done between RRI and eGFR showed a mild but statistically significant correlation between RI and eGFR (r = −0.28, P = 0.04).

Conclusions:

Renal artery RI is raised in most subjects with breast cancer and correlates significantly with the eGFR as determined by cystatin C alone.

Published: August 2022

Background:

Stroke accounts for a significant proportion of neurological disorders and carries a high morbidity and mortality. Hypertension and diabetes mellitus are the major risk factors for stroke in Nigeria.

Aims and Objectives:

The need to determine the pattern of radiologic changes of stroke in patients with hypertension or diabetes mellitus on computed tomography scan (CT) of the brain.

Materials and Methods:

A prospective study using CT of the brain of 104 adult patients with stoke per group was carried out. Results were analyzed using (SPSS) version 16.0 software. Proportion of pattern of stroke in each group was analyzed and possible association between the socio-demographic factors was determined.

Results:

104 diabetic patients (67 males and 37 females) and 104 hypertensive patients (68 males and 36 females) were studied. Their ages ranged from 30-90 years. Most of the patients had thrombotic stroke with the diabetic having a higher proportion (92.3%) than their hypertensive counterparts (66.3%). The parietal lobe is most affected part with (58.7%) in hypertensive's and 44.2% of the diabetics. The left side of the brain was most affected in more than 50% of both the hypertensive and diabetic stroke patients.

Conclusion:

Ischaemic stroke was equally prevalent in both diabetic and hypertensive patients while haemorrhagic stroke was more common among hypertensive patients. The parietal lobe and the left side of the brain were the more frequent area of predilection in both groups.
Ultrasonography and Magnetic Resonance Imaging Findings of an Occult Tibial Plateau Fracture
Authors: Aderibigbe Adeniyi Sunday , Ayoola Oluwagbemiga Oluyoola , Ashaolu Oludare Uriel , Komolafe Olurotimi Olufunto
Published: August 2022

We describe a case of posttraumatic lateral tibial plateau fracture that was not demonstrated by conventional radiography. Knee joint ultrasound showed mild lateral meniscal protrusion suggestive of an intra-articular injury, which was confirmed at magnetic resonance imaging to represent an occult lateral tibial plateau fracture. A high index of suspicion for occult fractures should be maintained in posttraumatic patients with ultrasound findings of meniscal protrusion, in spite of apparently normal X-ray findings.
Computerized Tomographic Patterns of Intracranial Tumors in Northwest Nigeria
Authors: Aliyu Suleiman , Ibinaiye Phillip Oluleke , Chom Nuhu Dung , Jimoh Abdullahi , Ibrahim Muhammed Zaria , Kingsley Okafor Emeka
Published: August 2022

Background:

Brain tumors are among the most challenging disorders encountered worldwide. Early and accurate diagnosis is essential for the management of these tumors. Different patterns of distribution of intracranial tumors have been described in various regions of the world, with previous reports in Africa suggesting that brain tumors were uncommon. This relative rarity has been attributed to low detection due to lack of neurosurgical and advanced neuroimaging facilities previously, a limitation that has now been gradually surmounted with the establishment of neurosurgical and more advanced radiological facilities on the continent.

Objectives:

The objective of this study is to describe the current pattern of intracranial tumors on computed tomography (CT) scan seen in Ahmadu Bello University Teaching Hospital (ABUTH) Zaria, Northwest Nigeria.

Methods:

This is a retrospective study of CT images of 60 patients of all age groups diagnosed with brain tumors between January 2015 and December 2019. The CT scans of the brain were performed using General Electric Hi-Speed NX/i dual-slice CT scanner (Germany). The age, sex, diagnosis using the WHO histological, and the pattern on CT were recorded, and data were analyzed using Statistical Package for the Social Sciences version 22.0, ARMONK, NY, USA 2013. Only cases with conclusive histology diagnosis were analyzed. This study was approved by the Health Research Ethics Committee of the ABUTH, Zaria (approval Number ABUTH/HREC/M36/2015), on January 23, 2015, before commencement.

Results:

In the 60 cases of brain tumors studied, patients' age range was 6 months–65 years, with a peak in the fourth and fifth decades of life (accounting for 38.3%). The mean age was 33.04 years ± 17.73 standard deviation. There was equal occurrence among males and females. About 96.7% of the tumors were primary and 3.7% secondary tumors; meningioma (MEN) (45%) was the most common tumor seen. About 45% of the cases were extra-axial, while 55% were intra-axial. Most (81.67%) of the tumors were located in the supratentorial region, while 18.33% were infratentorial. Headache (75%) and visual impairment (53.3%) were the most frequent clinical presentations.

Conclusion:

MEN was the most common tumor type seen in this study. This corroborates most studies in Nigeria and other African countries but contradicts some studies among Caucasians that showed glioma to be more common. This affirms that racial factors and environmental influence could have significant effects on the pattern of diseases. The results of this study will provide useful data on the pattern of brain tumors in this environment.

Published: August 2022

Background:

Coronavirus disease (COVID-19) is a pandemic that is ravaging the world. Chest imaging plays an important role in the diagnosis and management of patients with COVID-19-related chest infections. This study determined the pattern of chest radiographic features among confirmed COVID-19 patients in Abuja, Nigeria.

Materials and Methods:

Chest radiographs (CXR) of COVID-19 patients were reviewed, and the radiological features of the lesions were recorded based on the type of opacities, pattern of distribution in the lung fields, side of lesions, and severity of pulmonary abnormalities.

Results:

The radiographs of 77 patients were analyzed. Their age range was 15–88 years with a mean of 47.4 years and peak age group of 51–60 years. Gender distribution of the patients was 58 (75.3%) males and 19 (24.7%) females giving a male-to-female ratio of 3.1: 1. Fifty-five (71.4%) of the patients had normal CXRs, whereas 22 (28.6%) patients had abnormal pulmonary appearances. Seven (58.3%) out of 12 patients with mild interstitial pneumonia had unilateral disease, whereas 5 (41.7%) had bilateral disease. Combined total of ten patients with moderate and severe interstitial pneumonia all had bilateral disease.

Conclusion:

Plain CXR gives reliable diagnosis about the presence and degree of interstitial pneumonia in COVID-19 patients. CXR should be routinely done as a baseline diagnostic tool in patients positive for reverse-transcription polymerase chain reaction test. The findings in the CXRs of COVID-19 patients in sub-Saharan Africa are similar to those reported from the other parts of the world.
Existence results in large-strain magnetoelasticity
Authors: Bresciani Marco , Davoli Elisa , Kružík Martin
Published: August 2022

We investigate variational problems in large-strain magnetoelasticity, in both the static
and the quasistatic settings. The model contemplates a mixed Eulerian–Lagrangian formulation:
while deformations are defined on the reference configuration, magnetizations are defined on the
deformed set in the actual space. In the static setting, we establish the existence of minimizers. In
particular, we provide a compactness result for sequences of admissible states with equi-bounded
energies which gives the convergence of the composition of magnetizations with deformations. In
the quasistatic setting, we consider a notion of dissipation which is frame-indifferent and we show
that the incremental minimization problem is solvable. Then we propose a regularization of the
model in the spirit of gradient polyconvexity and we prove the existence of energetic solutions for
the regularized model.

Published: August 2022

OBJECTIVES: This study reports data regarding the awareness and practice of cancer prevention among Koreans in 2021 and behavioral changes during the coronavirus disease 2019 (COVID-19) pandemic.METHODS: We collected Cancer Prevention Awareness and Practice Survey data through face-to-face interview surveys using a structured questionnaire completed by 4,000 randomly selected men and women aged between 20 years and 74 years in 17 provinces. We examined the awareness and practice of 10 cancer prevention recommendations and evaluated their associations with potential risk factors through multiple logistic regression analysis adjusted for age, gender, residence, marital status, education, and income.RESULTS: Eighty percent of participants knew that cancer is preventable, while 45% practiced cancer prevention. Cancer prevention practice tended to be more common among older participants (adjusted odds ratio [aOR], 1.39 per 10-year increment; 95% confidence interval [CI], 1.29 to 1.49) and less common among rural inhabitants (aOR, 0.66; 95% CI, 0.51 to 0.86) than among urban residents and among single people (aOR, 0.55; 95% CI, 0.45 to 0.66) than among married people. Practices were the highest for avoiding burned or charred foods (87.6%) and lowest for vaccination against human papillomavirus (14.5%). Refusal to follow recommendations was most common for avoiding alcohol consumption (7.9%). The most difficult recommendations to follow were (1) regular exercise (57.7%); (2) maintaining a healthy body weight (46.1%); and (3) avoiding alcohol (40.1%). The most significant COVID-19-related changes were less exercise (32.5%) and increased body weight (25.6%).CONCLUSIONS: The awareness of cancer prevention was high, but the practice was low. Recommendations targeting awareness and practice need to be further promoted.

Authors: Alkalbani Razan Hamed , Gani Basheer Ahamed
Published: August 2022

Sultanate of Oman is targeting to implement renewable energy sources thirty percent of total energy sources within 2030. In line with the strategic plan, the hybrid model of solar and wind energy based highway lights is proposed on the Muscat highway. An attempt will be made to utilize the wind energy being generated through the movement of vehicles on the highway to change it to electrical energy to power the highway lights. Since the amount of electricity generated depends on the vehicle speed, wind direction, velocity and the placement of vertical axis wind turbines on the highway. In order to overcome the fluctuation of electricity generation, a hybrid model of solar and wind energy is proposed.to generate the maximum required electricity and provide continuous supply. As a first step in this research, the techno economic analysis has been carried out to evaluate the performance parameters such as energy production, capital expenditure, payback period and return of investment. As per the analytical model the payback period is approximately 3.2 years and the return of the investment of 221% are expected over the 10 year period The proposed next step in the research is to install hybrid model of PV solar cells and VAWTs on the median of the Muscat highways between As Seeb and Al Ruwi to see the potential to augment the electricity generation from the vehicle induced turbulence on the natural wind.

Published: August 2022

This study examines the scientific studies on the use of virtual environments and simulation programs in teacher training programs. Firstly, a search was made in the Web of Science database using the keywords simSchool and TeachLive. Four of the studies obtained as a result of the screening were excluded for various reasons (such as duplicate or off-topic publication) and the study was conducted with 22 scientific publications. The research results showed that virtual environments and simulations, which are widely and effectively used in many disciplines, also have a crucial potential in teaching and training. Most of the studies subject to analysis suggested that the use of virtual environments and simulation in education has positive effects such as self-confidence, time management, and classroom management. The research findings were discussed within the framework of the relevant literature, and suggestions were made.

In this content analysis, the authors examined articles from three international STEM journals to highlight and indicate if there were any trends for iSTEM research from 2013 to 2018. Of the 296 articles analyzed in this content analysis, 41 investigated the integration of STEM disciplines. Findings revealed that integrated STEM (iSTEM) education research is often qualitative and occurs in the United States. This study also indicates an upward trend in the percentage of iSTEM education research from 2013 to 2018, and many of the articles focused on middle school students. A closer examination of the introductions, backgrounds, and literature reviews of the 41 articles revealed four explicit definitions for iSTEM education. Furthermore, STEM and Education were the most frequently used author keywords and ERIC descriptors.
Addressing Anxiety in Hospitalized Adults Using a Music Intervention
Authors:   , Rochon Raina
Published: August 2022

Practice Problem: The practice problem is anxiety related to hospitalization among adults in an acute care setting. Increased anxiety can lead to other issues while hospitalized including disruptive behaviors. PICOT: The PICOT question that guided this project was: In hospitalized medical-surgical adults (P), how does the implementation of a music intervention as an adjunct to standard distraction techniques (I) compared to standard care (C) affect symptoms of anxiety as observed by the rate of behavior de-escalation team calls (O) within eight weeks (T)? Evidence: There were five systematic reviews, four systematic reviews with meta-analysis with high level of evidence, high quality rating, and high quantity of articles included emerged that led to the project. Evidence supported the use of a music intervention for therapeutic distraction and reduction of anxiety. Intervention: The intervention was a music intervention of a personalized music selection for approximately 30 minutes prior to procedures or when anxiety or disruptive behavior was noted in addition to standard care. Outcome: Music intervention use increased by 68 individual sessions during the intervention period from baseline. Utilization of the de-escalation team decreased 80% from the preceding 10 weeks prior to implementation. Data collection difficulties reduced observation of knowledge change, however, activities related to the intervention increased during the intervention period. Conclusion: The use of music as an intervention to decreasing anxiety and the use of a de-escalation team for disruptive behavior was successful though the process outcomes were not met. Staff engagement will be key in making this a sustainable practice and additional interventions for staff engagement are necessary.
El dibujo infantil del mundo vegetal y la comprensión del concepto de ser vivo en España y República Dominicana
Authors: Muguerza Olcoz Raquel
Published: August 2022

La comprensión del concepto del ser vivo inicia a temprana edad, con la representación de abstracciones y sus relaciones a través de las creencias e ideas previas sobre el tema. Estos conceptos serán enmarcados desde un informe investigación cuantitativa con el análisis de los dibujos y la comprensión del ser vivo en torno a la vida vegetal de una muestra de niños y niñas de España y República Dominicana, con edades comprendidas entre 4 y 7 años. Los resultados demuestran que entre los colores con mayor presencia en los dibujos estudiados se encuentran el negro, el rojo, el rosa y el violeta. Los resultados demuestran que existen diferencias significativas entre las edades, los países y el sexo, siendo las niñas más jóvenes quienes plasman con mayor frecuencia estos colores sobre el mundo vegetal. A medida que los niños crecen y mejoran el desarrollo cognitivo realizan mejores representaciones del mundo vegetal.

Este artigo é um recorte da pesquisa de Mestrado, a qual foi desenvolvida junto à linha de pesquisa“Inovação para EPT”, do Programa de Pós-Graduação em Educação Profissional e Tecnológica(CTISM/UFSM), e apresenta como objetivo geral elaborar material didático digital (MDD) para apoiodas práticas de ensino dos professores da disciplina de Contabilidade Introdutória. Esse objetivo sejustifica por ser a Contabilidade uma área de ensino com escassos materiais didáticos digitais para usodos professores em suas práticas docentes. Os autores que embasaram este estudo foram: Andrade(2015); Peleias (2006, 2007); Felder-Silvermann (1988, 2002); Amiel (2018), Filatro (2018), entreoutros. Optou-se por uma pesquisa aplicada, por se tratar de um estudo com a finalidade de resolverproblemas identificados no âmbito da vivência do pesquisador. Como resultado foi desenvolvido umsite, chamado de “REA_CONT1”, de acesso livre e gratuito, que reúne um acervo de atividades econteúdos variados, os quais servirão de apoio aos professores, assim como o site tambémdisponibiliza tutoriais para que os professores possam desenvolver seus próprios materiais didáticos etenham um caminho inicial para se apoiar. O site foi avaliado qualitativamente por professores ealunos do ensino superior e técnico, e os dados coletados serviram para atestar que a pesquisa atingiu oobjetivo proposto. Ademais, contribui para as práticas docentes dos professores e para o estudo e arevisão de conteúdo dos alunos. O trabalho terá continuidade, ampliando a elaboração de materiaispara outras áreas que não a Contabilidade Introdutória.
From the Dreyfus Affair to Zionism in Palestine: Rashid Riḍā’s Views of Jews in Relation to the ‘Christian’ Colonial West
Authors: Ryad Umar
Published: August 2022

The ideas of the well-known reformist Sheikh Muḥammad Rashīd Riḍā (1865-1935) in his journal Al-Manār (Lighthouse, 1898-1935) still inspire many academic researchers who are interested in the study of the Muslim world in the first decades of the twentieth century. As one of the most influential advocates of Arab nationalism and pan-Islamism, Riḍā’s critiques of Zionism and Jewish expansion in Palestine were part of his anti-colonial activities against the ‘Christian’ west. The article discusses how Riḍā was frustrated that European powers let down the Arabs by supporting the Jews in establishing their homeland at the cost of the rights of its indigenous habitants. We shall argue that Riḍā’s harsh views of Zionism should be understood as a mixture of religious rhetoric, nationalist ambitions, resistance to Turkish policies, and political frustration with Europe’s ‘unjust’ colonial policies and special political privileges given to the Jews in Palestine. In the early years of the twentieth century, Riḍā anticipated the progress of the Jews in establishing a nation of their own in Palestine, but his concerns grew after the British Mandate in 1922. The article looks at how Riḍā, in his confrontations with Zionism and Judaism, combined these debates with other ideas on freemasonry, the authority of the Church, the crusades, and the role of Jesuits in curbing the asserted increasing Jewish power in Europe. The article highlights how Riḍā’s Islamic national outlook against the Jews and Zionists in Palestine bears the character of religious and political ferment against the ‘Christian’ west.
EXPERIMENTAL INVESTIGATION ON EFFECTIVENESS OF ADDING ZEOLITE
TOSODIUM BICARBONATE FIRE SUPPRESSANT POWDER
Authors: Mohamed Harshad Harif K P  , Anandkumar.M.K  , M.Anandakumar  , S.Saravanakumar
Published: August 2022

Sodium bicarbonate is commonly used fire suppressant powder because of its high efficiency and low
cost. Two main factors affecting the effectiveness of sodium bicarbonate is moisture absorption and cake
formation. From the literature survey, it has been found that, by adding small quantities of zeolite particles
to sodium bicarbonate the above issues can be eliminated. Also, by adding zeolite the surface area
available for each particle increases, which will eventually increase the efficiency. The project aims in
experimenting zeolite added sodium bicarbonate fire extinguishing powder and finding out its
effectiveness in suppressing. A new type of particulate fire suppressant powder was prepared, in which
zeolite of different concentration are added. By the experimental results, it is found that the zeolite added
sodium bicarbonate suppressant powder has better performance than the conventional sodium
bicarbonate, with relatively shorter extinguishing time and a smaller number of agents required to
extinguish the fire. Based on experimental study and mathematical modelling in MATLAB software it is
found that the optimum concentration of zeolite in sodium bicarbonate was obtained as 7.939 percentage
and extinction time was 1.125 seconds
