Authors: المصري مصطفى
Published: January 2022

على الرغم من مبادرات التحول تجاه الطاقات البديلة المستدامة في العالم، لا زال البترول المُستخرج من مكامن الأرض أحد أهم الاكتشافات الاقتصادية في عصرنا الراهن؛ حيث يُعتبر المصدر الأول والأساس للطاقة، ومحور معظم إنتاج الصناعي والزراعي، ومحرك التطور العلمي والاجتماعي الحاصل في المجتمعات المعاصرة، علاوةً على أنه المُنطلق والركيزة الأساسية للتحول الطاقوي التدريجي، التي تُبنى عليه الخطط طويلة الأمد. منذ إنتاج أول برميل نفط؛ أريق الكثير من الحبر في صياغة أطُرٍ تعاقدية تنظّم قطاع النفط والغاز. في حين أن جميعها لديها هدف شامل مشترك؛ إلا أن وسائل منحها، كذلك تأثير نتائجها، تختلف. كيف تعاملت وسائل منح امتيازات استكشاف النفط، لا سيما عقد اقتسام الإنتاج، مع موازنة علاقة الأطراف عبر سلسلة البنود المنصوص عليها داخلها؟ يدعونا بيتر روبرتس، مُحامٍ وكاتبٌ للعديد من المؤلفات المتخصصة في اتفاقيات التشغيل المشترك، إلى استكشاف إجابات هذا السؤال من منظور الدولة المانحة للامتياز البترولي، حثًّا منه على استخدام عقد اقتسام الإنتاج كوسيلة منح؛ لما له من أهمية استراتيجية للإطار القانوني المُعتمد من قبلها. يحاول كتابه الموسوم بـ «دليل عملي لوسائل منح امتيازات استكشاف النفط» (الصادر عن دار نشر جامعة قطر، 2020) الإجابة عن هذا السؤال من خلال تسليط الضوء على أهم مفاصل وسائل منح امتيازات استكشاف النفط «الجزء (A) من الكتاب (15%)»، كذلك من خلال دراسة معمّقة لبنود عقد اقتسام الإنتاج؛ بندًا تلو الآخر؛ «الجزء (B) من الكتاب (72%)».

Published: January 2022

Accelerating infrastructure development in Indonesia is a good thing, but this is not without problems. The COVID-19 pandemic is a problem that has a large and global impact, not least in Indonesia, especially in the construction industry sector. The construction project of the Soedono Madiun Hospital is one of the construction projects that have experienced the direct impact of the COVID-19 pandemic. Therefore, the purpose of this study is to review and analyze the impact of the covid-19 pandemic on construction projects in the case study of the construction project of the Soedono Madiun Hospital, and to find out the biggest impact of the covid-19 pandemic which has the most influence on construction projects in the case study of the construction project of the Soedono Hospital. Madison.

The research method used to determine the biggest impact of the covid-19 pandemic on the cost and time aspects is the multiple linear regression analysis method with the help of Microsoft Excel. The other data analysis methods used in this study were the validity and reliability tests used in testing the questionnaire.

The results of data analysis conducted in this study indicate that there are seven independent variables affect the dependent variable, namely the suitability of planning and project realization with the equation y= 94.186-0.376x1-0.108x2-1.014x3+0.873x4 for the time aspect, and the equation y=87,009 -0.0006x5-0.001x6-0.0002x7 for the cost aspect. With this equation, it can be seen that the independent variable that has the most influence on the dependent variable on the time aspect is the independent variable X3, namely the change in the time schedule due to delays in the arrival of construction materials by 1.014, while in the cost aspect is the independent variable X6, namely changes in costs due to instability. the price of construction materials is 0.001. So, it is hoped that there will be a project management handling that focuses on the most influential variable, namely construction materials.

Published: January 2022

La contaminación del aire, el cambio climático y la reducción de la diversidad biológica son amenazas importantes para la salud humana. En las últimas décadas se ha observado un aumento en las enfermedades alérgicas incluyendo asma y rinoconjuntivitis. Hasta al 40% de la población mundial pueden presentar alguna enfermedad alérgica representando un impacto significativo en la calidad de vida de quienes la padecen, siendo la contaminación ambiental una de las causas de su presentación. La contaminación del aire causa morbilidad y mortalidad significativas en pacientes con enfermedades inflamatorias de las vías respiratorias como rinitis alérgica, rinosinusitis crónica, asma y enfermedad pulmonar obstructiva crónica. El estrés oxidativo en pacientes con enfermedades respiratorias puede inducir inflamación eosinofílica en las vías respiratorias, aumentar la sensibilización alérgica atópica y aumentar la susceptibilidad a infecciones. El cambio climático ha influido en la exposición a alérgenos extramuros y se asocia con exacerbaciones de enfermedades de la vía respiratoria superior e inferior. La interacción de las exposiciones ambientales en interiores y exteriores y los factores del huésped pueden afectar el desarrollo y la progresión de enfermedades alérgicas de por vida. La reducción de la exposición a los contaminantes del aire se ha asociado con una respuesta favorable en la salud respiratoria por lo cual es necesario implementar medidas que contribuyan a la mejoría en la calidad del aire.

Los betalactámicos son los antimicrobianos más utilizados por su seguridad y eficacia. En este grupo se incluyen las penicilinas, las cefalosporinas, los carbapenémicos y los monobactámicos. La penicilina constituye la primera causa de alergia a medicamentos: 10 a 20 % de la población se etiqueta como alérgica a la misma, en muchas ocasiones erróneamente. Se ha reportado reacción cruzada entre penicilinas y cefalosporina en 2 a 5 %. No hay reacción cruzada entre penicilinas y aztreonam, pero sí con ceftazidima. En la fisiopatología de las reacciones de hipersensibilidad a penicilina se incluyen todos los mecanismos de la clasificación de Gell y Coombs. La estratificación de acuerdo con el riesgo permite tomar la decisión más objetiva para etiquetar al paciente como alérgico. En la evolución natural de la alergia a la penicilina, 80 a 90 % de los pacientes pierde dicha sensibilidad a los 10 años. De ser indispensable, el paciente puede ser sometido a un protocolo de desensibilización. El médico inmunoalergologo es una pieza clave en la selección del paciente, la elaboración de los protocolos de reto y la desensibilización en un ambiente controlado.
Enhancing Performance in Mathematics Through Motivation, Peer Assisted Learning, And Teaching Quality: The Mediating Role of Student Interest
Authors: Arthur Yarhands Dissou , Dogbe Courage Simon Kofi , Asiedu-Addo Samuel Kwesi
Published: January 2022

In the Sub-Saran Africa, mathematics is a key subject in the school curriculum and most countries consider it as must-pass subject to gain admission into tertiary institutions. This notwithstanding, students’ performance in mathematics in a cause for concern. For example, the mathematics performance of Ghanaian students in 2021 West Africa Senior Secondary Certificate Examination (WASSCE), was lower than that of 2020. This indicates that the percentage of students to gain admission into the tertiary has reduced. This study therefore explored the role of motivation, peer assisted learning, quality of teaching and student interest on student performance in mathematics. The study design was a survey, with structured questionnaire being used for data collection. The population comprised of students pursuing their undergraduate degree at a public university in Ghana. Purposive and convenient sampling techniques were used in selecting 373 first year undergraduate students of Akenten Appiah-Menka University of Skills Training and Entrepreneurial Development (AAMUSTED), who studied on Kumasi campus. Data was gathered during lecture hours, after permissions were sought from the lecturers handling the classes at the time of data collection. The path analysis was by Structural Equation Modelling, by using Amos (v.23) software. It was concluded that students learning interest in mathematics partially mediated the relationships between mathematics learning motivation and performance in mathematics; as well as between mathematics teaching quality and performance in mathematics. The effect of peer assisted mathematics learning on performance in mathematics was however fully mediated by students learning interest in mathematics.
How Did Students Perceive Classroom Learning under Strict COVID-19 Pandemic Closures and Restrictions?
Authors: Sako Takayoshi
Published: January 2022

The COVID-19 pandemic of 2020 required strict infection prevention measures worldwide, including school closure. After school reopened, we implemented Japan’s strict COVID measures, under which close contact in pairs or groups, as well as vocalizing in unison, was proscribed, with students having to remain quiet and face the blackboard.

This study’s aim is to answer the question of how students felt about learning under such extreme constraints. One of the most noticeable findings from the responses to the survey of the 2020 class was that they felt the lack of collaborative learning experiences; hence, in 2021, we implemented changes that would allow for more collaboration while still adhering to COVID prevention guidelines. Among the various collaborative learning activities in the classroom, students reported that they found value in debate activities that challenged their English language skills and critical thinking. Overall, however, students found comfort and value in a semblance of learning with their peers.

It was concluded that even in a volatile and uncertain situation, such as a pandemic, it is crucial to improve environments for collaborative learning. In the future, quantitative study of the impact of collaborative learning on students’ English proficiency will be a useful follow-up study.

Published: January 2022

ABSTRACT Writing is often regarded as a difficult skill to acquire by majority of EFL learners. Teaching writing is also unquestionably challenging. It is argued that an essential effort to assist learners is having them explore information to write through reading topic and genre- related sources extensively. This article seeks to explain the result of a study employing R&D method to develop a Reading-Based Model to teach academic writing. It will report the results of the needs analysis briefly and then explain the model itself. The data about the students' needs of writing according to the students and the writing lecturers were collected through questionnaire and interview. The results of needs analysis and relevant literature confirmed that reading prior and during writing is elemental. The syntax of the model was developed on the basis of literature dealing with the principles of reading-writing relations and the Genre-based Approach. It consists of 4 main stages. Some activities within each stage can be carried out online. The model has gone through a validation process by two experts (two experienced lecturers teaching writing skills). The model was considered valid by the experts; a few recommendations were concerned with additional activities.

Sri Lanka has a free education system that gives access to higher education opportunities through the G.C.E. (Advanced Level) examination to a limited number of students. Students can choose their preferred university course if they have fulfilled the required minimum results for university admission. This paper discusses the general interests and attitudes of a sample of physical science stream students towards university education in STEM as a case study in Sri Lanka. The study has investigated several perspectives of the selected sample of G. C. E. (A/L) students through an online survey that includes questions regarding students' attitudes and perceptions on university education and different STEM-related undergraduate courses. The study has covered several schools of three provinces in Sri Lanka, and some of the investigated results are discussed with respect to the provinces. The results revealed career prospects, the academic quality of the undergraduate courses and the reputation of the university as the most influencing factors for undergraduate course selection in STEM disciplines, while engineering-related undergraduate courses were the most preferred ones among the students. The study results can be an asset to further studies since this topic has been rarely explored in the Sri Lankan higher education context.

Published: January 2022

In geotechnical engineering, ground movement caused by excavations is a challenging issue. The excessive differential settlement generated by soil movement induced by wall deflection may cause damage to nearby structures. A detailed literature review on the general deformation behavior of deep excavation support systems is presented in this paper. Many factors, such as normalized horizontal deflection (δh-max/He%), vertical displacement (δv-max/He%), δvmax/δhmax ratio, settlement influence zone (Do), etc., can play significant roles in describing the deflection behavior of the excavation system. A descriptive analysis of the reviewed data was carried out. The concluded δh-max/He% values range between 0.17 to 1.5, with a mean value of 0.58 for soft clay, while in the case of sands and stiff clay soils δh-max/He% value ranges between 0.07 to 0.40, with a mean value of 0.20. δv-max/He% values range between 0.13 to 1.10, with a mean value of 0.49 for soft soil, while its value ranges between 0.02 to 1.10, with a mean value of 0.24 in the case of sands and stiff clay soils. The settlement influence zone (Do) reaches a mean distance of 2.3He, which falls within Do=1.5-3.5He in the case of soft clays, while Do reaches a mean distance of 2.0He and 3.0He in the case of sands and other stiff clay soils, respectively. The relationship between system stiffness and excavation-induced wall and ground movements was discussed. Unfortunately, the literature review offers limited data regarding system stiffness, the 3-D nature of excavation support systems, excavation processes, and time effects.
Evaluation of the steady state performance of a squirrel cage induction motor using per-phase equivalent circuit

Published: January 2022

The performance evaluation of cage induction motor continues to receive tremendous attention because of its vital effect on the overall system stability. The model has predicted the behavior of cage induction motor under different operating conditions and in selecting the appropriate motor for a specific load application. There is often a challenge when a squirrel cage induction motor is connected to a time-varying load, particularly when the motor is selected without considering the effects of pulsating torques. The usual method used for steady state analysis of induction motors is the equivalent circuit method. Using the per phase equivalent circuit of the induction motor, stator current and referred rotor current were computed using simple circuit analysis. Once the currents are available, then power can be computed because the voltage is already known.

This study evaluated the effect of upgrading the quality of maize stover (MS) on milk nutritive value. The study involved feeding MS improved using urea (U), chopped groundnut stover (cGS), chopped soybean stover (cSS), mineralized groundnut stover solution (mGS) and mineralized soybean stover solution (mSS) to lactating dairy cows. The feeding trial involved twelve (12) dairy cows in their second parity. Effect of supplementation with MS improved with U, cGS, cSS, mGS and mSS on milk quality was evaluated following on-station feeding trials. The study involved 22 factorial experiments within a Completely Randomised Design (CRD). Milk samples were analysed for protein, lactose, fat and solid not fat (SNF). Mean milk protein levels ranged from 3.52mg/ml to 3,73mg/ml (s.e=0.03) for milk from cows fed on MS improved using cGS and mGS respectively. Protein and Lactose were observed to be the least variable (3.64g/ml ±0.12, and 5.24g ±0.24 respectively). Average milk fat content was highest (4.78%, se=0.52) in milk from cows fed on UET treated MS and lowest (3.43%, se=0.52) in milk from cows fed on gGS protein based MS. Within legume type milk fat was higher(4.75%±1.99) in milk from cows fed on MS blended with mGS than that in milk from cows fed on MS improved with cGS (3.43%±1.99). Similar result was observed in milk fat from cows fed on MS improved with the use of soybean. Lactose in milk from cows fed on UET treated MS was highest (5.51g, se=0.061) and lowest (5.10g, se=0.061) in milk from cows fed on MS blended with cGS. Milk from cows fed on MS improved with mGS was higher (9.61p/cwt, se=0.14) in SNF and lowest (8.88p/cwt, se=0.14) in milk from cows fed on MS with cGS. The milk density values ranged from 32.65sg, se=0.53 for milk from cows fed on UET treated MS to 30.42sg, se=0.053 for milk from cows fed on MS blended with cGS. Milk components were higher when cows were fed on MS improved using mineralized legume stover solutions.
Characterization of asphalt binders extracted from field mixtures containing RAP and/or RAS
Authors: Eslam Deef-Allah  , Magdy Abdelrahman
Published: January 2022

The use of reclaimed asphalt pavement (RAP) and/or recycled asphalt shingles (RAS) in the asphalt mixtures is a common practice in the U.S.A. However, there is a controversy to date on how RAP/RAS interact with virgin asphalt binders (VABs) in asphalt mixtures. For mixtures containing RAP/RAS, the aged asphalt binders in RAP and air-blown asphalt binders in RAS alter the performances of the extracted asphalt binders (EABs). Thus, the rheological properties of EABs from these mixtures require more investigation. The focus of this paper was relating the high-temperature properties of EABs from field cores to the corresponding rolling thin film oven aged virgin asphalt binders (RTFO AVABs). Furthermore, a comparison of the effect of RAP and RAS on the high-temperature rheological properties of EABs was another objective. Different asphalt cores were collected from the field within two weeks after the pavement construction process in 2016. These cores represented eight asphalt mixtures with different asphalt binder replacement percentages by RAP, RAS, or both. The asphalt binders were extracted from these mixtures and considered as RTFO AVABs. The high-temperature rheological properties included the temperature sweep and frequency sweep testing and the multiple stress creep recovery testing. The EABs had higher stiffnesses and elasticates than the corresponding RTFO AVABs because of the aged binders in RAP/RAS. The binders in RAP interacted more readily with VABs than RAS binders.

Published: January 2022

Enterococcus faecalis is an etiological agent of endodontic infections. The present study was performed to investigate the gene profiles of E. faecalis induced by type I collagen stimulation. E. faecalis ATCC 19433 was cultivated with [collagen (+)] or without type I collagen [collagen (−)], and transcriptome analysis was performed using high-throughput sequencing technology. A total of 3.6 gb of information was obtained by sequence analysis and 77 differentially expressed genes (DEGs) between the two culture conditions were identified. Among the 77 DEGs, 35 genes were upregulated in collagen (+) E. faecalis, whereas 42 genes were downregulated. Gene Ontology (GO) enrichment analysis was performed and 11 GO terms, including metalloendopeptidase activity (GO:0004222) and two related GO terms (GO:0031012, GO:0044421), were significantly enriched in the set of upregulated genes. We focused on an upregulated DEG belonging to the matrixin metalloprotease gene family, and matrix metalloprotease (MMP) activities of the bacterial cell were examined. The generic MMP, MMP-8, and MMP-9 activities of collagen (+) E. faecalis were significantly higher than those of collagen (−) E. faecalis. These results suggested that contact with type I collagen may alter the gene expression profile of E. faecalis, and upregulation of metalloprotease genes may result in enhanced MMP activities in E. faecalis.

Incontinence is an individual's involuntary incontinence of urine and/or feces. It is a serious health problem that significantly affects the individual's mental health and quality of life. Women experience incontinence 3-4 times higher than men, and the prevalence of incontinence continuously increases with age in both sexes.

The diagnosis, treatment, and rehabilitation process affect an individual psychologically, physically, socially, and emotionally. Women who suffer from incontinence restrict daily life, such as not exercising, traveling, and having social and emotional interactions. Over time women socially isolated and may lose their self-confidence. It decreases the quality of life with feelings of shame, depression, anxiety, and discomfort. This process affects women's mental health.

The review aims to examine the effects of incontinence on women's mental health and quality of life in line with current researches and suggestions that women's health and psychiatric nurses implement in the clinic areas.

Purpose: Few studies are available that evaluate oncology nurses’ health beliefs related to smoking and smoking status. The purpose of this study was to evaluate the health beliefs regarding smoking among nurses and status working in a cancer hospital.

Methods: This descriptive study was conducted among 152 nurses in a cancer hospital in Turkey. Data were collected by using The Self-Report Questionnaire Regarding Health Beliefs and Smoking Cessation Self-Efficacy Questionnaire

Results: Median age, body mass index, and working duration with cancer patients of the oncology nurses are 34.0, 23.9, and 9.0, respectively. Of the nurses, 54.1% stated that they have never smoked, while 27% smoke every day. Among regular smokers, 32.1% are in precontemplation stage. Of the participants, 91.9% noted that ‘smokers are more likely to have cancer, 45.9% that ‘it is difficult for smokers to quit smoking, and 52.3% that ‘tobacco bans are effective on quitting smoking.

Conclusion: The majority of oncology nurses think that a healthy lifestyle is very important but a few of them follow the advice. Also even though the nurses mostly have healthy living beliefs they can’t reflect these on their behaviors. Nurses working with cancer patients must also be considered as risk groups when planning cancer prevention and tobacco control studies. It is important that nurses should be informed and supported to take part in smoking cessation interventions.

Objectives: This study was carried out to determine the extent to which the academic satisfaction of nursing students predicted their burnout levels. Methods: This is a descriptive study. The sample consisted of 424 nursing students. Data collection tools were developed by the researchers by reviewing the literature. In the study, a Socio-Demographic Characteristics Questionnaire, a Faculty of Education Student Satisfaction Scale, and the Maslach Burnout Inventory-Student Survey were used. Results: Results indicated that 71% (n = 301) of the students were female, 62.5% (n = 265) were in the 20-23 age group, 57.5% (n = 244) had selected nursing voluntarily, 63.9% (n = 271) were currently satisfied with their department, and that 77.1% (n = 327) had future unemployment concerns. Also, the burnout levels of nursing students were determined to be affected significantly by the attitudes of the instructors (β = -0.177), the satisfaction levels explained 13.8% of the depersonalization levels, and the accomplishment level was significantly affected by the course and the syllabus (β = 0.102). Conclusion: The satisfaction of nursing students with the institution and education was determined to reduce their burnout levels significantly.

Purpose: The aim of this study is to perform the Turkish adaptation study of the Health Protective Behavior Scale.

Methods: This was a methodological study that was conducted between August 2020 and September 2020. The sample of the study consists of 384 individuals aged 18-59 living in the city center of Kayseri. In this study, "Descriptive Information Form" and "Health Protective Behavior Scale (HPBS)" were used as data collection tools. The reliability of the scale was evaluated by internal consistency, Pearson correlation, and test-retest reliability. The construct validity of the scale was tested by exploratory factor analysis and confirmatory factor analysis.

Results: According to the results of the explanatory factor analysis, 40.748% variance was explained in 4 dimensions in the scale. In the confirmatory factor analysis, a four-dimensional structure was found to fit well (X2/df=2.213 RMSEA=0.056). As a result of the reliability analysis of the scale, it was found that the internal consistency coefficient was α = .82 and the test-retest reliability was r = .81.

Conclusion: It has been determined that HPBS is a valid and reliable measurement tool to determine health protective and development behaviors.

Purpose. Study pore size effect and morphology of mesoporous silica on metoprolol tartrate release.Methodology. A sample of hollow mesoporous silicon dioxide with amino-functional groups containing 12.7 wt. % metoprolol tartrate has been investigated as potential carriers for the controlled release of active substance. Studies of the release profiles of metoprolol tartrate were performed under the following conditions: dissolution medium was buffer solution with a pH of 7.4 (phosphate buffer); sampling time: from 0.5 h before 18 h. The metoprolol concentration in the liquid phase was evaluated by a UV-Vis spectrophotometer (Persee TU-190, Beijing, China) by use of quartz cuvettes with an optical path length of 1 cm at a maximum wavelength of 274 nm.Findings. In this work we have studied mesoporous silica as possible carrier to controlled release of metoprolol tartrate, a drug used in the treatment of some diseases of the cardiovascular system. The material for research was a sample of hollow mesoporous silicon dioxide with amino-functional groups 200–400 nm in size and 20–30 nm in shell thickness. A calibrated curve to determine the amount of metoprolol was constructed by determining the absorption dependence of the concentration of metoprolol in the range from 10 to 300 ppm. The same drug concentration was obtained as calculated from the drug release test formula, which concludes that the release of metoprolol is controlled.Originality. The controlled release of a sample of hollow spheres of mesoporous silicon dioxide filled with metoprolol tartrate was studied, which was synthesized by the School of Chemistry and Chemical Engineering, Qilu University of Technology, using a new technology, where hollow spheres of mesoporous silicon dioxide with amino groups were synthesized using CO2 gas bubbles as templates.Practical value. The metoprolol release amount could achieve a 50% release amounts within 1 hour and 90% within 5 hours, indicating that the synthesized mesoporous hollow sphere could achieve controlled drug release, and shows the potential of carriers with stimulus response and targeted therapy.

Purpose. Monitor different sources of water supply in a particular region of Ukraine. Methodogy. To monitor the drinking water of the selected settlement of Cherkasy region, water from the water supply network (10 samples), water from the pump room (1 sample) and water from wells (26 samples) were selected and analyzed for 20 main chemical indicators in accordance with the requirements of DSanPiN 2.2.4-171-10 and DSTU 7525: 2014. Findings. It was found that tap water has a slight excess of iron and turbidity in 5 samples. The water does not contain aluminum, ammonium ions, nitrates, nitrites, residual amounts of free and bound chlorine and chlorination by-products. The sample of water from the pump room has a slight excess of silicon and salts of general hardness – calcium and magnesium ions. Water from the pump room in chemical composition (pH, dry matter, alkalinity, chlorides, sulfates, sodium) and the content of microcomponents is very similar to tap water, it has a slightly higher "color" and "turbidity", but the content of petroleum products and iron does not exceed drinking standards. water – 0.1 mg / dm3 and 0.2 mg / dm3, respectively. In this case, well water is the most unsuitable for drinking purposes. It was found that the largest excess of normalized values in these waters was observed when determining the dry residue (up to 4 standards), hardness (up to 5 standards), nitrate concentration (up to 9 standards).Originality. Monitoring of drinking water in the selected settlement of Cherkasy region and the analysis of the suitability of tap water, pump room water and well water for drinking needs.Practical value. The peculiarities of the chemical composition of drinking water supply facilities of this settlement have been established, in particular, much attention is paid to the determination of microelements and persistent organic toxicants at the level of their maximum permissible concentrations. The analysis of the obtained results testifies that the quality of tap water and pump room meets the current hygienic standards in terms of organoleptic parameters, general mineralization, hardness, alkalinity, content of organic components, and water in almost all wells does not meet.
