Published: March 2022

Abstract
Businesses nowadays have been adapting to technological advancements since the start of the 21st century to promote their products. The majority of the global population has been exposed to the digital world, and businesses have engaged themselves in the online environment. Social media tools have become a vital component in advertising products and have contributed significantly to creating countless innovations. Using social media has given online businesses options for managing their performance towards their brand and interacting with consumers through social media platforms. These digital improvements have benefited the consumer electronics industry. The goal of the study was to gain a thorough understanding of how social media platforms and tools impact the performance of online retail businesses in the consumer electronics industry. The study used the quantitative approach, and online survey questionnaires were distributed to 185 respondents. Results revealed that perceived ease of use, social media advertising, and electronic word-of-mouth (eWOM) all have a positive effect on the performance of online retail businesses in the consumer electronics industry. The implications of this research aim to benefit aspiring online business owners, consumers, and future researchers, and help them maximize social media to make them stand out from prospective competitors.

What are the Critical Factors that Affect the Habitability of Celestial Bodies in Our Solar System?
Authors: Sharma Yash , Turban Stephen
Published: March 2022

The study of habitability on planets and celestial bodies apart from Earth has gathered increased interest over the last few decades due to grand technological advancements. Space agencies like NASA are spending billions of dollars on spacecraft, probes, and satellites for this specific purpose, but as of now, no one knows what different (and possibly quite similar) species reside in our solar system, and where they live (moons, planets). However, a planet/moon being habitable to life is not that easy, and there are hundreds of factors that can make a celestial body habitable.  This paper will cover a few of the several factors: existence of liquid water, atmospheric composition, chemical composition of the planet's surface, and biofuel, along with linking these factors to different celestial bodies in our solar system, specifically focusing on Mars, Venus, Europa, and Titan.
Application of OLS Regression and VAR Models to Analyse the Economies of Varying Political Regimes
Authors: Ganeriwalla Amrita , Mehta Swapneel
Published: March 2022

The GDP per capita is a popular method of measuring the economic success of a country. This paper uses regression analysis to predict the GDP per capita (GDPPC) of countries using different independent variables. We applied Ordinary Linear Squares Regression and Vector Autoregression to check for a correlation between the chosen independent variables (Corruption Perception Index, Political Rights score, Civil Liberties score, Gender Inequality Index, Consumer Price Index, Population Density, and the percentage of people using the Internet) and the GDPPC. Using empirical evidence, we determine which model might be more accurate to attain this goal. Four countries of varying political regimes are studied - USA and Canada are categorised as democratic countries and China and Russia are non-democratic countries. Our results show trends in the correlations between the independent and dependent variables, and we can draw a distinction between the political regimes.  We found that Corruption Perception Index and Population Density negatively correlates with the GDPPC of all 4 countries. We also noticed that the percentage of people using the internet and Gender Inequality Index correlates negatively with the GDPPC for non-democratic countries and in democratic countries the Consumer Price Index negatively influences the economy.
STEM Interest in Elementary School Children
Authors: Dukkipati Naya , Novak-Herzog Maya
Published: March 2022

STEM is a fast-growing field, and it is becoming increasingly important with technological innovations; however, the STEM workforce is still predominantly composed of men. This paper will highlight how these gender disparities may be emerging at a young age by examining differences in female and male self-efficacy and the impact of the school environment. It will also provide an alternative model to the STEM pipeline. The purpose of this study is to determine whether disparities are occurring at an elementary level, and if so, what factors they may be the result of. Currently, most research is focused on how these disparities emerge in higher education; thus, this research aims to see if there is another key group being excluded by existing research.

Effective of Modern Techniques on Content-Based Medical Image Retrieval: A Survey
Authors: Rashad Metwally , Nooh Sameer , Afifi Ibrahem , Abdelfatah Mohamed
Published: March 2022

The advancement in medical imaging has resulted in a rapid and large increase in medical images inside repositories. These medical images contain very important information that can be used in many things, including diagnosing diseases. This implies that a precise, efficient way of indexing and retrieving biomedical images is necessary to obtain medical images from such repositories in real-time. CBMIR, therefore, played an important part, where the CBMIR’s area is very important in the field of image processing and involves low-level feature extraction and similarity measures for the comparison of medical images such as color histograms, edges, texture, shape. The majority of the methods already in use in CBMIR enhance the retrieval of a medical image and diseases diagnosis by reducing the issue of the semantic gap between low visual and high semantic levels. Also, secure access to the medical image of diverse cases, which are often kept on a network and are susceptible to malicious attacks is considered an important target for all medical practitioners. So, most CBMIRs try to cover this target for the purpose of privacy preservation. So, in this survey, the most advanced (CBMIR) frameworks that were used to reduce the issue of semantic gaps, high dimensionality feature maps were covered, disease diagnosis, and medical image security. Furthermore, the different publicly and standard databases used in measuring the performance of these frameworks also were covered.

Este estudo apresenta uma análise qualitativa do medicamento Amoxicilina suspensão 250mg/ 5ml, utilizando o método de Ressonância Magnética Nuclear (RMN). Foram comparados os sinais de ¹H-RMN e ¹³C-RMN de um padrão de amoxicilina com medicamentos vencidos (3 anos) e no prazo de validade sendo observadas mudanças dos sinais referentes a molécula de amoxicilina. Os medicamentos não sofreram nenhum tratamento prévio para análise sendo apenas dissolvidos em dimetilsulfóxido (DMSO-d6) para a realização dos experimentos e foram realizados com os mesmos parâmetros de ajuste do equipamento. Para comparação dos sinais foi realizada a sobreposição dos espectros não sendo observada ausência de nenhum dos sinais referentes ao fármaco. A utilização de comparação dos sinais mostrou-se bastante intuitiva e de fácil interpretação e não foram observadas diferenças significativas nos sinais do fármaco em ambos os medicamentos, válido e vencido.
الارتقاء بالمشاركة الوالدية في برامج الطفولة المبكرة
Authors: احميده فتحي
Published: March 2022

تعدّ الأسرةُ أولَ مؤسسة اجتماعية يتعامل معها الطفل، وهي البيئة الثقافية التي يكتسب منها لغته وقيمه وأفكاره واتجاهاته. ويمضي الطفل معظم وقته في البيت يتفاعل مع البيئة المنزلية والأفراد المحيطين بها، ويتأثر بممارسات والديه وأفرد أسرته. كما تعد الروضة المؤسسة الاجتماعية الثانية التي يتعامل معها الطفل، وتلعب دوراً كبيراً في تطوير نموه وتعلمه. فالبيت والروضة هما أهم عالَمَين في حياة الأطفال الصغار، حيث يتنقل الطفل بين هذين العالَمَين في رحلة تعلمه الأولى (Dodge, Colker, & Heroman, 2010). لذلك باتت الحاجة ماسّة إلى تواصل دائم ومستمر بين البيت والروضة، لبناء شراكة متينة بين العاملات في الروضة وأولياء الأمور، تقود إلى مشاركة حقيقية في برامج الروضة التعليمية (Epstein, 2013).

لذلك يرى التربويون أن معلمات رياض الأطفال الناجحات هُنَّ من يشجعن المشاركة الوالدية وينظرن إلى أولياء الأمور على أنهم أصدقاء وشركاء حقيقيين، ويحرصن على دمجهم في برنامجهن التربوي إعداداً وتنفيذاً وتقويماً. لذلك لم يعد الحديث عن مشاركة أولياء الأمور في برامج الطفولة المبكرة ترفًا تربويًا، وإنما باتت مشاركة أولياء الأمور جزءاً لا يتجزأ من برامج الروضة التعليمية (Ihmeideh, & Olimat, 2015). فدمج أولياء الأمور ومشاركتهم في برامج الروضة يعد من الركائز الرئيسة التي ترتكز عليها الممارسات المرتبطة في معظم برامج الطفولة المبكرة للقناعة التامة بأن الأسرة أهم مكان لنمو الأطفال وتعلمهم، وأن أولياء الأمور هم أول معلمي الأطفال وأهمهم، بل وأكثرهم تأثيراً عليهم. فما تقوم المعلمات ببنائه داخل الروضة من الممكن أن يهدمه أولياء الأمور داخل البيت إن تم إقصاؤهم عن الروضة وبرامجها وتجاهل دورهم، وعدم إحاطتهم بالمعرفة اللازمة بطرائق متابعة تطوير نمو أطفالهم وتعلمهم.

إنَّ تجربة الوطن العربي في بناء الدولة ومفهوم المواطنة على أساس الإنتماء العربي وضمن سياق إنساني أوسع مبني على العدالة والتحرر من الإستعمار والإستعمار الجديد والإستبداد كانت قصيرة رغم بعض النجاحات المتفرقة. ولكن، ما ميّزها عن التجربة الأوروبية هو استمرارية وجود تحولات جيوسياسية عميقة ومتقلبة سواء على الصعيد المحلي أو الإقليمي أو الدولي. وما زال لشعوب المنطقة الطاقة والعزم للسعي نحو العدالة الإجتماعية ومناهضة الإستبداد رغم التضحيات الكبيرة. تأتي هذه الورقة لتناقش مفهوم التوجه العابر-استعماري كمفهوم مغاير للدولة وكمولِّد فكري ومعرفي للتحرّر وتسعى إلى الخروج بتوصيات لبناء استراتيجية فلسطينية من حيث إنتاج الحيّز المغاير للحيّز الاستيطاني الاستعماري لتمهيد الطريق إلى مستقبل فيه عدالة إجتماعية ومكانية. تنقسم الورقة إلى ثلاثة أجزاء: الأول يستعرض مسار الدولة الحديثة وتطوُّر مفهوم القومية في أوروبا في القرن التاسع عشر ومن ثمَّ مسار الدولة في الوطن العربي في بداية القرن العشرين مع توضيح إشكاليّاتهم. والثاني يعرض مفهوم عابر-الاستعمار كطرح مغاير لمفهوم الدولة، والثالث يعرض مدخل نحو نموذج عابر-استعماري فلسطيني.

Biosimilar treatment in paediatric gastroenterology – current view
Authors: Bronský Jiří
Published: March 2022

Biosimilar drugs (BSD) have been used in the field of gastroenterology since 2013, when the European Medicines Agency approved biosimilar infliximab for the treatment of inflammatory bowel disease (IBD). The view of these drugs has changed significantly in the course of their use. At first, BSDs were used with hesitation, mainly due to the lack of published data on their efficacy and safety and also due to the lack of clinical experience. Over the following years, a number of studies were published that gradually support their importance in the treatment of IBD, and BSDs are now routinely administered to patients naïve to biological treatment, and a number of centres perform switches from the original treatment to a BSD. In paediatrics, a more reserved attitude towards their clinical use persisted for a long time, but with the growing amount of published data, they are also common in clinical practice. This summary article describes the development in the approach of both international and domestic professional societies and physicians-clinicians to the use of BSL and provides references to newly published studies of biosimilar drugs.

The communication pattern is not only need a communication pattern only face to face, because in this era of globalization, digital communication patterns are very necessary and must be improved, such as making contracts and sanctions for customers who doesn’t report that their cellphone number has changed, or provide an unregistered phone number, and banks You must also be more careful in entering the debtor's number so that mistakes don't occur. Because so far there are many debtor numbers that cannot be contacted or misconnected, and face-to-face communication also needs to be improved, so far BTN KC Sharia Medan has used two communication patterns, namely digital communication patterns and digital communication patterns. face-to-face communication by visiting the debtor's house directly, the digital communication pattern is only about 20 percent resulting in clarity of customer payments, and if it continues to be unable to be contacted, a visit to the debtor's house will be made, but visits also sometimes create controversy between branch collections and debtors, because the debtor feel ashamed of the surrounding community, both family and neighbors and based on this, the purpose of this research is to find out the branch collection communication pattern in the process of collecting non-performing financing to debtors/customers either through digital or face-to-face. In this research, descriptive research method is used using a qualitative approach through interviews with respondents

İnsan ve Eylemleri Arasında Bir Dönüşüm Aralığı Olarak Niyet
Authors: Gündüz Muhammed Muhdi
Published: March 2022

İnsanlığın kadim meselelerinden olan özgür irade mevzusu yaşanılan dönemin düşünce yapısına göre farklı şekillerde tartışılmaktadır. Her şeyin yaratıcısı olan Allah’ın karşısında eylemlerinden sorumlu bir varlık olan insanın özgürlüğü konusu, İslam düşünce geleneğinde mülahaza edildiği görülmektedir. Mezkûr gelenekte Allah’ın mutlak adil olduğundan yola çıkılarak insanlara zulmetmeyeceği, dolayısıyla insanların eylemler üzerinde tasarruflun olması gerektiği vurgulanmaktadır. Günümüzde ise sinir bilimindeki veriler ışığında insanın özgür irade konusunun farklı boyutta gündeme tekrar geldiği görülmektedir. Güncel bilimsel veriler eylem sürecinin bilinç dışındaki nöron faaliyetleri ile başladığından yola çıkarak insanın özgür irade sahibi olmasının bir yanılsamadan ibaret olabileceği iddia edilmektedir. Ancak her iki yaklaşımda kişi ve eylemleri arasında anlam kazanan niyet ile insanın eylem sürecinde aktif rol oynama imkânına sahip olduğu ifade edilmektedir. Niyet, özgür iradenin somutlaşmış hali olmakta olup niyet edebilme özelliği ile de insan eğitime açık bir varlık halini almaktadır. Buna uygun olarak çalışmada insanın niyet eden bir varlık olarak özgür irade sahibi olduğu dolayısıyla eğitilebilme özelliği kazandığı konusu ön plana çıkarılacaktır. Nihayetinde bu çalışmada niyetin İslam düşünce geleneğindeki sevk eden ve eyleme yönelme anlamlarının insanın eğitilmesine sağladığı imkânlar gündeme getirilmektedir.
Ali b. İsmail el-Aksarâyî’nin ‘Risâle fî Hakki’d-Duhân’ Adlı Risâlesinde Kullandığı Mâide 33. Âyetinin Bağlamı

Published: March 2022

Bir metni doğru bir şekilde anlayabilmek, sadece o metinde geçen kelimelerin manalarını bilmekle mümkün olmayabilir. Kelime manalarının yanında ayrıca metin içi ve metin dışı bağlama baş vurmak, metni doğru anlamak için gereklidir. Bu durum Kur’ân’ın anlaşılması için de geçerli olup, âyetlerin doğru bir şekilde anlaşılabilmesindeki önemli unsurlardan biridir. Bu manada bağlam, âyetlerin kendi içerisinde sahip olduğu doğru mananın ortaya çıkarılmasına yardımcı olur. Ali b. İsmail el-Aksarâyî, tütün konusunu ele aldığı risâlesinde onun haramlığını dört başlıkta ele almakta ve birincisinde Mâide 33. âyetini delil getirerek tütünün haramlığına hükmetmektedir. Bu çalışma, Aksarâyî’nin risâlesinde kullandığı söz konusu âyetin bağlamına yoğunlaşmakta müellifin bu hususu dikkate alıp almadığını tespit etmeyi hedeflemektedir. Bu çerçevede çalışmanın giriş kısmında bağlam konusuna kısaca değinildikten sonra Aksarâyî ve risâlesi hakkında, risâlenin metni ve Türkçe çevirisi verilmek suretiyle, bilgi verilmiştir. Daha sonra ise ilgili âyetin bağlamı tespit edilmeye çalışılmış, Aksarâyî’nin ilgili âyeti bağlamından kopardığı tespit edilmiştir.

Authors: Martillo Alchundia Ivette , Alvarado Zabala Julio , Saltos Murillo Marisela
Published: March 2022

La investigación surge tras la identificación del desconocimiento del impacto que genera el uso de las nuevas tecnologías de la información y el internet en los estudiantes de bachillerato de la Unidad Educativa Abdón Calderón en el cantón Milagro, provincia del Guayas, en Ecuador. Es así que se plantea como objetivo analizar el uso de las tecnologías de la información y la comunicación en el proceso de enseñanza como estrategia para el desarrollo de las clases virtuales. Para ello se planteo como metodología de investigación una indagación cuali-cuantitativa. El análisis cuantitativo se llevó a cabo por medio de encuestas direccionadas a 150 alumnos, 15 educadores y 5 directivos, mientras que el análisis cualitativo se fundamentó en la observación de los sucesos, es decir de como los educadores impartían las clases virtuales. Los resultados demostraron que los educandos poseen bajos conocimientos de las TICs a favor de su educación, pero reconocen su importancia en el proceso formativo, mientras los educandos asumen no conocer adecuadamente las plataformas para impartir las clases virtuales y mencionan la escasa capacitación que reciben al respecto. Se observó además que los docentes no motivan a los estudiantes y tampoco se interesan porque logren una comprensión de los contenidos a través del uso de las herramientas digitales.

The Role of Islamic Microfinance in Poverty Alleviation: Evidence from Pakistan
Authors: Ahmad Waqas
Published: March 2022

This study aims to develop and propose an Islamic microfinance model that can be used for poverty alleviation in Pakistan. Other than investigating poverty, other interrelated aspects were also considered in which entrepreneurship, conventional microfinance, and Islamic finance were included. Moreover, by moving beyond and further exploring, this research presents various uses of Islamic microfinance to reduce poverty. A set of primary data was collected through interviews to carry out this research. Initial findings of the study unveil that poverty exists concerning common perceptions such as lack of necessities, unemployment, poor health, and insufficient financial resources. However, child selling, unethical ways of earning such as begging, robbery, and incompetency of the skilled person were the findings representing poverty from totally different perspectives. Moreover, the studied results also reveal that few respondents were aware of the concept and use of conventional microfinance. Still, at the same time, all the respondents represented the forbiddance of interest. Findings also represent the unawareness about Islamic microfinance's concepts, practice, and importance. This research is helpful as it presents the idea and the use of Islamic microfinance for the impoverished people of Pakistan and how it can be a beneficial alternative for reducing poverty. Moreover, it also seeks the attention from the financial institutions in the Country that how the beliefs and expectations of poor people are important in reducing their poverty. The significance of this study broadens the scope of the neglected concept of Islamic finance generally and Islamic microfinance particularly.

Most drilling rigs are designed based on the max static load on the hook of great travelling system structure as 6×7. But when change the depth of the well, the load on the hook changes, so it was necessary to determine the travelling system structure, which ensures the best design indicators  of hoisting system.

This research studied the impact of travelling system structure on design parameters of hoisting system and the best indicators of hoisting systems at less drilling lines number suitable with max allowable load on hook   for oil and gas wells drilling units.

In this work, A methodology depending on graphical solution for hoisting system indicators curves has been developed. (MATLAB) has been used in order to develop a program that facilitates the application of this methodology and accelerate the work. The most important technical parameters for different drilling unit, in addition to the allowable hookload, by using the most important design indicators that positively or negatively affecting the system with changing travelling system structure. This program depending on graphical solution for set of these indicators in relation with number of drilling lines by finding equilibrium point between positive and negative effects that has the algebraic sum of the slopes is as close as possible to zero. This point represent optimal drilling lines compatible with hookload at practical technical parameters for drilling units.

This study achieves the best indicators for hoisting system working at ideal travelling system and decrease the time required for drilling by increasing hook velocity rate by 12% and the efficiency of hoisting system by 10%. In addition, the lengths of drilling line rate decreased by 40% that cause reduction in material cost and achieving better economic feasibility in comparison with design travelling system.

Published: March 2022

The fluid mixture hydrocyclone is an excellent tool for downhole oil/water separation (DOWS) for high water cut. In the present work the flow through inline axial inlet hydrocyclone is investigated computationally using ANSYS-FLUENT-19 software. The three dimensional continuity and momentum equations with SST k-omega turbulence model are used to simulate the strongly swirling, turbulent flow. Oil/water two phase mixture treated as the working fluid, water is considered as the primary phase and oil is the secondary phase. The considered oil volume fraction this work is 0.25 and flow split is 0.3 for three different flow rates of (14, 28, 56) m3/hr corresponding to Reynold's number range of (1.6 to 6.6)*104. The pressure and velocity fields were analyzed in the whole hydrocyclone with core recirculation. The results are helpful to predict the flow motion inside the cyclone to estimate the oil/water separation process. The present work indicates that the water purity at cyclone exit was 90%, while the obtained oil purity was 38%.

Abstract

Through this research, copper oxide nanoparticles were prepared via precipitation method using copper nitrate as a starting material. The resulting nanomaterial characteristics were diagnosed using available technologies such as AFM, XRD, B.E.T. surface area, pore-volume, pore size, and FTIR.

For modern industries, lubricants are efficient materials for reducing friction between moving surfaces. CuO nanoparticles are used as an additive that is dispersed in an oil phase. Ultrasound technique was used to disperse the nanomaterial in Stocks 60 base oil, and the effect of the ratios of the added nanomaterial on the final properties of the oil was studied. A ratio of 0.5, 1, 1.5, and 2% was used and mixed with an approbate amount of oleic acid and was dispersed using ultrasound.

The prepared copper oxide nanoparticles had an average particle size of 31.76nm and crystallinity of 93.63%. The surface area was around 27.61 m2 / g.  Diagnostic tests were carried out on the oil, as it led to an increase in the viscosity index gave high stability and good dispersion of the nanomaterial for a long time, as the viscosity index was re-examined during successive periods. The final characterization of the oil shows a good improvement in the viscosity index of 110 and the flashpoint increased to 240 ° C. By increasing the viscosity index leading to ease movement inside the tools and contact surfaces oil will overcome the severe conditions during operations.

Published: March 2022

Abstract

     In a centrally ignited constant volume chamber, an experimental research on the laminar flame speed of premixed gasoline/ethanol/hydrogen/air mixtures is undertaken at varied initial pressures (0.1-0.3 MPa), constant initial temperature (593 K), and variable equivalency ratios (0.75-1.5). The mixing method is based on the energy replacement principle, and various component blending ratios are tested. This has necessitated the construction of a specific laboratory experimental equipment. The flame speeds are measured using the Shelerian photography technique using a high-speed camera. The results reveal that adding hydrogen to dual fuel mixtures has a considerable impact on stretched laminar flame speed. The stretched laminar flame speeds for 20 percent H2-80 percent G, 40 percent H2-60 percent G, and 60 percent H2-40 percent G are 3.71 m/s, 7.329 m/s, and 11.0267 m/s, respectively, at 0.1 MPa initial pressure and stoichiometric mixture. For 20 percent H2-80 percent G, 40 percent H2-60 percent G, and 60 percent H2-40 percent G mixtures, the un-stretched flame speed at atmospheric pressure and stoichiometric is computed and found to be 1.23 m/s, 3.67 m/s, and 7.093 m/s, respectively. When the initial pressure is increased, both stretched and un-stretched flame rates drop. "

    The results of the triple fuel mixes demonstrate that the influence of ethanol addition on the stretched laminar flame speed is significant at constant hydrogen blending ratios, with 2.24 m/s at 20% H2-16% E-64 percent G and 2.68 m/s at 20% H2-32 % E-48 % G at 0.1 MPa for stoichiometric mixture. For dual fuel combinations, the effect of starting pressure on stretched and un-stretched flame speeds is the same. Where the flame speed has a maximum value for stoichiometric combustion, the equivalence ratio has a greater effect on flame speed. "
