Effects of Piston motion on the power generated by Stirling cycle machines
Authors: Hazmy Majed 
Published: June 2023

This paper uses a simple model to estimate the power output of Stirling engine when giving the pistons a continuous motion with a prescribed pattern, fixed frequency, and a variable phase shift for different operational temperature ratios. Two continuous motions patterns, sinusoidal and modified sinusoidal, have been examined against the discontinuous motion of the ideal cycle. The power produced from engines having continuously moving pistons is lower than the power produced from the ideal cycle. The power ratio decreases as the temperature ratio increases. the highest produced power with a temperature ratio of 1.5, is 97% of the ideal cycle and it occurs at a phase-shift of 81o. Operating at ±10o off the highest power phase shift condition reduces the output power by 5-7%. For modified sinusoidal motion, the highest output power is 88% when the phase shift is 55o. Operating at ±10o off the maximum power phase shift condition reduces the output power by 2%. Moreover, at the highest output phase shift condition, the power output ratio drops from 97% to 93%, for sinusoidal motion as the cycle temperature ratio changes from 1.5 to 3. For modified sinusoidal motion, the output power drops from 88% to 78% at the highest phase shift condition.

Mobile ad-hoc social networks (MASNs) have been the subject of several research studies over the past two decades. They allow stations located in a small geographical area to be connected without the need for a network infrastructure and offer them the possibility to communicate any time anywhere. To communicate, stations regularly broadcast their interests in the form of keywords. Stations with a high degree of similarity among their keywords can communicate with each other. However, the coverage of MASNs is limited to a small geographical area, due to the limited communication range of mobile ad-hoc networks (MANET) stations. In this paper, we present an architecture and implementation of hybrid mobile ad-hoc social networks (MASNs coupled to infrastructure networks) of Android mobile devices for information dissemination. Stations can use the infrastructure network to communicate and rely on the mobile ad-hoc network when the infrastructure is not available.Rather than communicating synchronously as this is the case in the similar works found in the literature, in our approach, the stations communicate using a publish/subscribe communication protocol, which is perfectly suited to this type of network thanks to the decoupling in time and space it provides.
Les réseaux sociaux mobiles ad hoc (MASN) ont fait l'objet de plusieurs recherches au cours des deux dernières décennies. Ils permettent à des stations situées dans une petite zone géographique d'être connectées sans avoir besoin d'une infrastructure de réseau et leur offrent la possibilité de communiquer à tout moment et en tout lieu. Pour communiquer, les stations diffusent régulièrement leurs centres d'intérêt sous forme de mots-clés. Les stations dont les mots-clés présentent un degré élevé de similitude peuvent communiquer entre elles. Cependant, la couverture des réseaux MASN est limitée à une petite zone géographique, en raison de la portée de communication limitée des stations des réseaux mobiles ad hoc (MANET). Dans cet article, nous présentons une architecture et une mise en œuvre de réseaux sociaux mobiles ad hoc hybrides (MASN couplés à des réseaux d'infrastructure) d'appareils mobiles Android pour la diffusion d'informations. Les stations peuvent utiliser le réseau d'infrastructure pour communiquer et s'appuyer sur le réseau mobile ad hoc lorsque l'infrastructure n'est pas disponible.Plutôt que de communiquer de manière synchrone comme c'est le cas dans les travaux similaires trouvés dans la littérature, dans notre approche, les stations communiquent en utilisant un protocole de communication de type publication/abonnement, qui est parfaitement adapté à ce type de réseau grâce au découplage dans le temps et l'espace qu'il fournit.

يتناول هذا البحث الأسرار البلاغية في سورة الصافات، واتبع الباحث فيه المنهجين، الوصفي والتحليلي، وهدفت الدراسة إلى بيان الأسرار البلاغية في سورة الصافات، من حيث الفرق بين الفصاحة والبلاغة عند القدامى والمحدثين، والضوابط البلاغية قبل نزول القرآن الكريم، والضوابط البلاغية بعد نزول القرآن الكريم، وتوصلت الدراسة إلى أن الأذواق تختلف في فهم الآيات القرآنية، الذي يستحسنه ذوقي، لا يستحسنه ذوقك، وأن هذه الأسرار البلاغية في سورة الصافت توضح الإحساس الوجداني بين الباحث والقارئ حتى تحصل المشاركة الوجدانية بينهما، وأن الآيات القرآنية التي حفلت بالأسرار البلاغية في سورة الصافات كانت همتها تتجه إلى تدريب الطلاب والدارسين على الانتفاع بالتناسق الفني بين طرفي الصور الفنية عقليا وشعوريا، فالتطبيق هو الثمرة الموجودة من كل علم، فلا قيمة لعلم من العلوم إلا إذا طبقت قواعده، وأن فهم الأسرار البلاغية في سورة الصافات؛ يجعلنا ندرك من غير شك مرونة اللسان العربي، وهذا مما يلمسه هذا البحث.

This research deals with the rhetorical secrets in Surat Al-Saffat, and the researcher followed the two approaches, descriptive and analytical. And the study concluded that tastes differ in understanding the Qur’anic verses, which my taste prefers, but your tastes do not. Its mission is to train students and scholars to benefit from the artistic coordination between the two sides of the artistic images mentally and emotionally. The application is the existing fruit of every science. There is no value for a science of science unless its rules are applied, and understanding the rhetorical secrets in Surat Al-Saffat; It makes us realize without a doubt the flexibility of the Arabic tongue, and this is what this research touches.
الدّخيل في تفسير كشف الأسرار وهتك الأستار للإمام جمال الدين الصفدي سورة الأنعام أنموذجًا: دراسة تحليلية
Authors: Abdullah Snh Mohammed Salmeen , Zekkoub Abdelali Bey , Mohammed Abdo Yousef 
Published: June 2023

لقد تميز منهج الإمام الصفدي –رحمه الله تعالى- بقبوله للعقل والنقل كدليلين أساسيين في الدين، وباستشهاده من التوراة والإنجيل مع اعتقاده بتحريفهما، وهذا المنهج يُظهر الحاجة الماسة إلى دراسة الدخيل في تفسيره، فجاءت هذه الدراسة مبينة للدّخيل في هذا التفسير. والهدف الرئيس الذي سعى البحث لتحقيقه هو: بيان الدّخيل في تفسير كشف الأسرار وهتك الأستار للإمام الصفدي من سورة الأنعام أنموذجاً. واعتمد الباحث في هذه الدراسة على المنهج الاستقرائي التحليلي؛ لتتبع مواضع الدخيل في تفسير الإمام الصفدي، ثم المنهج الاستنباطي؛ لاستخراج أنواع الدخيل التي تم الوقوف عليها. وكان من أهم نتائج هذه الدراسة: أن تفسير الإمام الصفدي يعد من أنفس كتب التفسير، إذ يتميز بغزارة المادة العلمية، وقد حوى تفسيره فوائد جمة لا توجد مجموعة في كتاب واحد، وأيضًا اعتناء الإمام الصفدي بالإسرائيليات في تفسيره وأكثر من إيراده لها، وذلك من خلال نصوص التوراة والانجيل المقتبسة، وأيضًا قلة إيراد الإمام الصفدي لما أُثر عن النبي ﷺ من الحديث، وكذلك أقوال السلف من الصحابة والتابعين. هذا وإن الإمام الصفدي يرى ضرورة القول بالرأي والأخذ به في تفسير كلام رب العالمين، وقد تناولت الدراسة ثمانية أمثلة مما يعد دخيلاً تم تنقيته من تفسير الإمام الصفدي، من خلال سورة الأنعام، مبينية وجه الدخيل فيها، ودراسته دراسة علمية.

Al-Imam al-Safadi’s approach is distinguished by his acceptance of reason and transmission as two basic guides in the religion, And by his martyrdom from the Torah and the Injil, even though he believed that they had been distorted. This approach shows the urgent need to study the intruder in his interpretation. This study came to clarify the intruder in this interpretation. The main objective that this research seeks to achieve; the explanation of the intruder in the interpretation of the ‘Kashf al-Asrār Wahatk al-Astār’ of al-Imām Jamāl Al-Dīn al-Ṣafadī and its implications in Sūrah Al Anaam as a model. The researcher's method in this study is the inductive and analytical method. Among the most important results of this study were: The interpretation of Imam Safadi is one of the most important books of interpretation, It is characterized by the abundance of scientific material, His interpretation contained many benefits that there is no collection in one book. Also, Imam al-Safadi’s used too much the narrations of people of book in his interpretation, as well as he used texts from the Torah and the Injil. Also, despite his lack of mentionnig what was reported from the Prophet from the hadith, Likewise, the sayings of the Salaf from the Companions and the Followers. It is from that that Imam Safadi he sees the necessity of saying the opinion and adopting it in the interpretation. The study showed that the extraneous narrations pose a significant danger to the Islamic faith. The study dealt with eight intruders based in the interpretation of Imam al-Safadi - may God Almighty have mercy on him - from Surah Al Anaam.
أثر السياق القرآني في تخصيص عموم القرآن عند المحقق الخليلي آية التحريم في سورة الأنعام أنموذجاً

ملخص البحث
يعد المحقق سعيد بن خلفان الخليلي من العلماء الذين يقصدهم العامة والخاصة من أهل العلم وطلابه في القرن الثالث عشر الهجري من داخل القطر العماني وخارجه، وذلك لتوضيح ما استشكل عليهم من فهم آيات الكتاب العزيز. ولقد كان في كثير من أجوبته يفسر الآيات مستنداً على السياق القرآني، فالمتأمل يجد كتابه تمهيد قواعد الإيمان قد احتوى على كثير من الآيات التي فسرها ورفع ما اشتبه على الأفهام منها. لكن المشكل في الموضوع أن هذه التفاسير المتناثرة في الكتاب لم تعن بالبحث والتحليل والوقوف على منهج المحقق في تفسيرها وتوضيحها. لذا أتى هذا المقال ليقف على آية من آيات سورة الأنعام وهي آية التحريم انتهج المحقق منهج السياق القرآني في رفع اللبس عنها، وتخصيص العموم فيها، وقد تبنى الباحثان في هذا المقال المنهج الاستقرائي والتحليلي للوصول إلى نتائج مهمةً، منها على سبيل المثال: أن للسياق القرآني بنوعيه الداخلي والخارجي أثراً بارزاً في تخصيص العموم، وبيان المجملات، وترجيح المحتملات، ودفع ما يتوهم أنه تعارض بين الآيات.
ABSTRACT
In the thirteenth century AH, students inside and outside of Oman sought the advice of Sheik Saeed bin Khalfan Al Khalili to help them understand certain Qur'anic verses that they were having trouble comprehending. In many of his answers, he explained the verses based on the Qur’anic context as shown in his book “Tamhid Qawaeid Elliman” which contains many interpretations on that basis. However, these scattered explanations in the book were not concerned with research, analysis, and reliance on the scholar's approach in interpreting and clarifying them. Therefore, this article examines Sheik Saeed's approach in using the Qur'anic context to clarify misunderstandings of the Prohibition Verse in Surah Al-An'am as well as the allocation of the commons. Employing an inductive and analytical approach, researchers achieve several significant conclusions including that both internal and external Qur'anic contexts have an essential role in the allocation of the commons, summary explanation, possibilities outweighing as well as disputing any false motion that verses are in opposition

Authors: Afzal Ch Manahil , Khan Sajjad Nawaz , Baig Fahad Javed , Ashraf Muhammad Umair 
Published: June 2023

With globally increasing recognition of environmental sustainability, now businesses are also acknowledging the requirement of incorporating green practices into their company operation. The study aims in exploring the relation in between the concepts of some sustainability elements such as “green human resource management practices” (GHRMP) and variables like “environmental performances”, with the examination of environmental strategy and green innovation playing as a mediator. The study of GHRMP with respect to its elements such as green recruitment refers to selecting and hiring an employee who has significant knowledge about environmental sustainability. It also consists of an element named green training that refers to teaching and developing a set of skills in employees to take action while protecting the environment within the organization The author specifically examines the connection between them by using the resource-based view theory. They also tested their relationship using the manufacturing firm's ability, motivation, and opportunity (AMO) theory. A survey questionnaire research strategy was used in this study along with a simple random sampling of 247 managers from large manufacturing firms in Punjab of Pakistan. For data analysis, this research used the p-test based on PLS-SEM. The findings showed that the study elements have a direct and major influence on each other especially the GHRMP and strategic environmental approach complement each other in the presence of the sustainable innovative product by the organization. Additionally, environmental strategy (ES) also partially mediated the influence of sustainable innovative products can be termed green innovation (GI), and it has an impact on environmental performance. The result revealed significant suggestions for legislators and manufacturing industries, to promote environmentally responsible actions, manufacturing goods, plus some production methods through a successful incentive program to increase loyalty. To apply the analysis and apply the study variables in the selected large sample sizes that can also be retested for future research, further research can exclude the novelty and unique issue by replicating the same research in other regions of the world.

Objective: To compare the left atrial function utilising speckle tracking echocardiography in patients with low-risk and high-risk non-valvular atrial fibrillation.Methods: The descriptive, cross-sectional study was conducted at the cardiology department of Kafrelsheikh University Hospital, Egypt, from January 2021 to January 2022, and comprised low-risk atrial fibrillatin participants in group I, high-risk atrial fibrillatin patients in group II, and healthy controls in group III. After detailed medical history, the subjects underwent 12-lead electrocardigram, and echocardiographic assessment, including two dimensional, M-mode, tissue doppler, and speckle tracking of the left atrium. The association of left atrial strain with Congestive heart failure, hypertension, age &ge;75 (doubled), diabetes, stroke (doubled), vascular disease sex category (female) score was explored. Data was analysed using SPSS 28.Results: Of the 90 subjects, there were 30(33.3%) in each of the 3 groups. The mean age among the groups was significantly different among the groups (p=0.014). Left atrial ejection fraction and left atrial strain had an overall significant difference among the groups (p<0.001). Congestive heart failure, hypertension, age &ge;75 (doubled), diabetes, stroke (doubled), vascular disease sex category (female) score was negatively correlated with Left atrial ejection fraction and (p<0.001) and left atrial strain (p<0.001).
Conclusion: In individuals with atrial fibrillatin, there was a significant decrease in left atrial strain and left atrial function. The use of speckle tracking echocardiography allowed for a more detailed analysis of left atrial mechanics. The correlation of left atrial strain and left atrial ejection fractionwith Congestive heart failure, hypertension, age &ge;75 (doubled), diabetes, stroke (doubled), vascular disease sex category (female) score was significantly negative.Keywords: Atrial fibrillation, Electrocardiography, Echocardiography, Speckle.
Molecular Integrity and Antioxidants Status of Nile Tilapia (O. niloticus) Exposed to Indigofera tinctoria
Authors: Popoola Omoniyi Michael , Olowolafe Tunde , Eweola Paul Ayomide 
Published: June 2023

Pollution in aquatic ecosystems by various pollutants has been a concern in recent decades because of the devastating effect posed on the stability between the receiving water bodies and the biodiversity therein. Indigofera tinctoria has been used in a variety of fields, including health and medicine, as well as industrial applications such as textiles. The impacts of I. tinctoria on freshwater fishes, as well as the mechanisms underlying the biological effects, are, however, sparse. The goal of the study was to see how I. tinctoria affected Nile Tilapia (O. niloticus) juveniles' oxidative stress response, biochemical indicators, DNA disintegration, and protein profile. For 21 days, 6 varying concentrations were applied to the fish, including a control. The biochemical parameters in the test fish revealed a considerable variation in a dose-response manner. In I. tinctoria treated fish, the enzyme activity, when compared with control treatment, lipid peroxidation, DNA fragmentation, and oxidative stress all increased relative to the toxicant doses used. The protein profiling revealed a modification in the protein credentials in I. tinctoria-treated fish when compared to the control. As per the study, I. tinctoria is toxic to O. niloticus, particularly at higher doses. The results of this research could be applied to biomonitoring studies of I. tinctorial toxicity, particularly in industrial applications.
HIGHLIGHTS

Pollution in aquatic ecosystems is a concern due to its impact on biodiversity
Indigofera tinctoria, locally used as fabric dye was studied for its effects on Nile Tilapia juveniles
Study finds I. tinctoria toxic, causing oxidative stress and DNA fragmentation, potentially affecting niloticus' muscle protein expression
