This study investigates the selection of optimal dental composites through a Multi-Criteria Decision Making approach utilizing the Analytic Hierarchy Process (AHP) and Gray Relational Analysis (GRA) techniques. Six dental composite materials (A) SiO₂-ZrO₂, (B) BIS-GMA, UDMA and Bis-EMA blend, (C) Bis-GMA, UDMA, TEGDMA and Bis-EMA resins, (D) silorane and filler, (E) Bis-GMA, Bis-EMA and UDMA, and (F) SiO₂-Al₂O₃-K₂O were evaluated based on a set of Performance Defining Criteria (PDCs). The AHP method determines the following priority order for PDCs: shrinkage (PDC-2) > density (PDC-

The primary aim of this research is to present generalized findings concerning weighted Hermite-Hadamard type inequalities for φ_h-convex functions, employing diverse techniques such as Hölder's and Power mean integral inequalities. Consequently, our derived outcomes aim to encompass a broader scope compared to those delineated by [1]. This approach enables us to encapsulate both established and novel results as specific instances.

The aim of this study was to investigate whether the quality of care provided by primary care physicians and nurses varied according to levels of burnout and empathy. We conducted a descriptive study of the medical staff (nurses and family doctors) employed in the Bangladesh. There are fifteen district health facilities and one tertiary health center in the district. A voluntary, anonymous survey on burnout and empathy was sent by email to all 220 healthcare populations registered in the district between January 2023 and December 2023. The data distribution was examined using the Chi-square te

This article presents the results of research on practical predictions of a number of important operational and technological properties of materials and their explanation based on the quantum theory of granular structure. The impossibility of explaining the granular structure and related properties of materials based on classical concepts has led many researchers to the idea of the need for a quantum description of these properties and phenomena. The quantum theory of granular structure that we are developing is based on the universal Bogolyubov Hamiltonian for condensed quantum systems or on

The objective of this study is to develop an optimal sample size for use in medical research studies by plotting power as a function of effect size and sample size. The paper is designed as a tool that a researcher can use in planning and conducting good quality research and gives a discussion of various aspects of sample size consideration in medical research. The paper also covers the essentials of calculating power and sample size for a variety of applied study designs. Sample size computation for survey type of studies, observation studies, and experimental studies based on means and propo
