Extension of lower and upper solutions approach for generalized nonlinear fractional boundary value problems
No full text© 2022 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group on behalf of the University of Bahrain.Our main concern in this study is to present the generalized results to investigate the existence of solutions to nonlinear fractional boundary value problems (FBVPs) with generalized nonlinear boundary conditions. The framework of the presented results relies on the lower and upper solutions approach which allows us to ensure the existence of solutions in a sector defined by well-ordered coupled lower and upper solutions. It is worth mentioning that the presented results unify the existence criteria of certain problems which were treated on a case-by-case basis in the literature. Two examples are supplied to support the results
A Study of Resistance in Irfan Ahmed Urfi’s Short Stories: عرفان احمد عرفی کے افسانوں میں مزاحمت نگاری:ایک مطالعہ
No full textWhere the invasion of scientific inventions has eased the problems of man, it has introduced new problems as well. The problems of the modern age are also of a new type. These problems are not only limited to the identity crisis of the individual but also include the problems arising under the modern industrial system. Current affairs and contemporary issues have always been made a subject in Urdu fiction. However, the problems of the modern age are such a critical that every fiction writer cannot afford to subject them in writing. Manto and Asmat took in their fictions the critical issues of their era. On the one hand, they had to face resistance by readers and writers due to the violation of traditional themes. On the other hand, they themselves emerged as prominent names of resistance against social problems. In the present era, the example of Irfan Ahmad Urfi can also be taken so. He is not so prominent in the contemporary Urdu fiction scene because the reader has no insight to afford a second recitation after reading his short stories. His fiction is an open resistance against the evils of the modern age. In the article under review, an attempt has been made to present some colors of this resistance from his short stories.

Fractional-order boundary value problems solutions using advanced numerical technique
No full textThe main motivation of this study is to extend the use of the operational matrices approach to solve fractional-order two-point boundary value problems (TPBVPs), a method often employed in the literature for solving fractional-order initial value problems. Our proposed approach employs innovative operational matrices, specifically the integral operational matrices based on Chelyshkov polynomials (CPs), a type of orthogonal polynomials. These operational matrices enable us to integrate monomial terms into the algorithm, effectively converting the problem into easily solvable Sylvester-type equations. We provide a comprehensive comparison to demonstrate the accuracy and computational advantages of our proposed approach against existing methods, including the exact solution, the Haar wavelet method (HWM), the Bessel collocation method (BCM), the Pseudo Spectral Method (PSM), the Generalized Adams–Bashforth–Moulton Method (GABMM) and the fractional central difference scheme (FCDS) through numerical examples. Additionally, our proposed approach is well-suited for solving problems with both polynomial and non-polynomial solutions
Exploring the Lower and Upper Solutions Approach for ABC-Fractional Derivative Differential Equations
No full textThe lower and upper solution approach has been widely employed in the literature to ensure the existence of solutions for integer-order boundary value problems. Therefore, in this proposed study, our primary objective is to extend this method to establish the existence results for Atangna-Baleanu-Caputo (ABC) fractional differential equations of order 0<γ<1, with generalized nonlinear boundary conditions. We propose a generalized approach that unifies the existence criteria for certain specific boundary value problems formulated using the ABC fractional-order derivative operator, particularly addressing periodic and anti-periodic cases as special instances. The framework of the proposed generalized approach relies heavily on the concept of coupled lower and upper solutions together with certain fixed point results, including Arzela-Ascoli and Schauder’s fixed point theorems. By means of the generalized approach, we first define appropriate lower and upper solutions that bound the potential solution. We then construct a modified problem that incorporates these bounding solutions, ensuring the existence of a solution to the original problems without relying on iterative techniques. This approach involves verifying that the lower solution is less than or equal to the upper solution, and that both satisfy the given boundary conditions, thus guaranteeing the existence of a solution within the specified bounds. The inclusion of the specific examples with periodic and anti-periodic boundary conditions further reinforces the validity and relevance of our theoretical results

Appropriate Use of Oxygen Delivery Devices
No full textOxygen supplementation is one of the commonest drugs required for a patient in hospital. Appropriate oxygen supplementation as per the requirement of the patient is essential. This requires optimal oxygen delivery device from the vast armamentarium. This requires understanding basics of oxygen delivery devices and its appropriate selection. This review describes various commonly available devices. The author would also propose a chart for aiding oxygen delivery devices based on the existing literature.</jats:p
A Critique of the Methodology on the Book The Human Body in Islamic Art Past Heritage and Post-Islamic Developments
No full textWhile the study of Islamic art is not very rich in the study of the human image, Eva Beer’s book "The Human Body in the Islamic Art of the Past Heritage and Post-Islamic Developments" is one of the only books in this field. In this book, the author examines the human image in the art of Arabs, Iranians, Gurkhas, and Ottomans. He has been a lecturer at the Museum of Islamic Art for many years and wrote the book in 2004. Although the author's efforts to collect research data are commendable, there are criticisms of the way research and methodological issues in the book are handled. Deficiencies in book methodology have led to the breakdown of communication between the book and the reader, despite the novelty of the research. The present article attempts to examine and explain the shortcomings of the methodology of the book and provide suggestions for their solution
