Comparison of Experimental and Theoretical Results of Tool Wear Rate in Electrical Discharge Machining
Abstract: Though electrical discharge machining (EDM) process is capable for complex and precise machining of materials irrespective of their hardness, it has certain limitations like low material removal rate (MRR), high tool wear rate (TWR), etc. which restrict its application areas. In EDM, material removal from workpiece and tool takes place by means of sparking between them which is a quite complex process. So, it is difficult to predict material removal …

Hierarchical Computational Modeling of Physical Structure Across Quark, Nuclear, and Atomic Scales
Abstract: We present a modular, multi-scale computational framework that integrates physical modeling and visualization across quark, nuclear, and atomic scales within a unified pipeline. Developed to address the traditional fragmentation between sub-nucleonic, nuclear, and electronic representations, the system provides a continuous data flow and visualization bridge spanning from femtometers to ångströms. The framework consists of three primary modules: a particle-level module illustrating nucleons as confined quark-triplets with effective flux-tube geometries; a …

Finite Element Analysis of Tool Wear Rate in Electrical Discharge Machining and Comparison with Experimental Results
Abstract: Electrical discharge machining (EDM) is one of the precise non-traditional machining processes in which desired shape is obtained in workpiece using electrical sparks. In EDM, material removal from workpiece and tool takes place by means of successive sparks occurring between them. The tool wear is a critical problem in EDM as the change in tool shape directly affects the final shape of the workpiece. In this paper, finite element analysis …

Fatigue Design of Anode Supports on Offshore Structures
Abstract: This paper addresses the fatigue analyses results for external and internal anodes’ attachments on the offshore structures using finite element analysis, where a simplified empirical formula is also recommended. For anodes that may become subject to significant forces during installation and operation, the design of anode fastening devices shall be addressed in early design stage. Doubler and/or gusset plates may be required for large anodes. The anode steel should be …

Population biology of the Sleeper fish Eleotris vittata from New Calabar River , Port Harcourt, Nigeria
Abstract: The population of Eleotris vittata was studied in the New Calabar River over a period of twelve months with the aim of providing a baseline data for the management of the stock; this was due to unavailability of information on the status of the stock. Analysis for growth using the Von Bertalanffy function revealed that length infinity was 26.34cm, parameter of curvature was 1.18cm/year, and the growth performance index was …

The Role of Precision Agriculture in Enhancing Horticultural Crop Yields
Abstract: This article explores the quantification of lithium and mapping of mineral composition in crushed lithium ore utilizing two distinct calibration techniques with Laser-Induced Breakdown Spectroscopy (LIBS). Thirty samples from a pegmatite lithium deposit were analyzed, with representative mineral samples extracted, mixed with resin, and polished into disks. These disks underwent examination via an analyzer and an integrated mineral analyzer, facilitating mineral identification. The first calibration technique used empirical mineral chemistry …

Shelf Life of Unani Drugs: In Classical and Contemporary Era
Abstract: Nothing in this universe is immortal. Drugs also degrade with time. Thus significance and indispensability of stability testing is well recognized since ancient time. However, in the absence of sophisticated scientific technology ancient Unani physicians used to evaluate the shelf life of drugs by means of organoleptic characters. In this paper review of classical Unani literature of plants, minerals and animal origin and compound drugs has been discussed in detail …

Nano-Chemical Revolution in Vaccinology: A Study
Abstract: The development of traditional vaccines, reliant on attenuated pathogens or purified proteins, has historically been limited by slow development timelines, poor stability, and low immunogenicity requiring potent, often non-specific, adjuvants. This synthesis argues that the convergence of nano-material science and meticulous chemical engineering represents the next major paradigm shift in preventative medicine. Nano-materials, particularly Lipid Nanoparticles (LNPs) and various polymeric or inorganic scaffolds, have transitioned from theoretical constructs to essential …
