A Fuel Cell Control System for Performance Improvement under Variable Atmospheric Pressure Conditions

Received: 20 September 2024;  Published: 20 January 2025;  doi: 10.21926/rpse.2501001

Abstract

This work focuses on designing a control unit for improving Proton Exchange Membrane Fuel Cell (PEMFC) performance powering electric vehicles when operating in variable atmospheric pressure conditions, a current situation in mountainous countries with sudden changes in road altitude. The paper studies and analyzes the PEM fuel cell behavior working with hydrogen supply from a pressurized tank and oxygen input from atmospheric air supply in journeys with continuous variation of road level due to the orography. The w [...]

Influence of Thermal Environment Conditions on Mechanical Properties of MEX Printed 17-4 PH Stainless Steel

Received: 18 February 2024;  Published: 22 August 2024;  doi: 10.21926/rpm.2403020

Abstract

This study investigates the influence of thermal environmental conditions during printing and their effects on the mechanical properties of material extrusion (MEX) 3D-printed 17-4 PH stainless steel. Various ambient temperatures and cooling behaviors were used during the printing process of the tensile specimens. Following DIN EN ISO 50125 and DIN EN ISO 6892, the study analyzes tensile strength, elongation and yield strength. The results demonstrate that the thermal environmental conditions affect both tensile an [...]

Effects of Ficus Platyphylla-Induced Hypothermia on Long-term Functional Recovery after Ischaemic Stroke

Received: 19 October 2023;  Published: 05 December 2023;  doi: 10.21926/obm.neurobiol.2304200

Abstract

A stroke is a cerebrovascular disease that results from a blockage in the blood supply to part of the brain or a burst blood vessel in the brain. It is the second leading cause of death worldwide, with an annual mortality rate of about 5.5 million. Antithrombotic therapies have failed to provide a cure for this debilitating cerebrovascular disorder, and hypothermia is gaining interest as a novel strategy for the management of stroke. In this study, we evaluated the effects of Ficus platyphylla-induced hypothermia o [...]

Understanding the Scope of the Contemporary Controversy about the Physical Nature and Modeling of the Action Potential: Insights from History and Philosophy of (Neuro)Science

Received: 09 October 2024;  Published: 13 February 2025;  doi: 10.21926/obm.neurobiol.2501269

Abstract

According to mainstream neuroscience, the action potential (AP) is a purely dissipative electrical phenomenon that should be modeled as such. However, also (essentially) reversible mechanical, thermal, and optical changes in the neuron have been reported to accompany the movement of the AP along the axonal surface. These are not accounted for in the prevailing (bio)-electric theory of neuronal excitability, originally introduced by Hodgkin and Huxley (HH) and mathematically formulated in their famous HH model of th [...]

Spark Plasma Sintering of Cu-Ti-Ni Ternary Alloy: Microstructural, Thermal and Electrical Properties

Received: 28 December 2023;  Published: 01 July 2024;  doi: 10.21926/rpm.2403016

Abstract

High strength and good conductivity are both critical parameters for copper-based alloys for electrical and other technological applications. This study is aimed to produce copper alloys and metal matrix composites (MMCs) with enhanced physical properties. Cu-Ti-Ni ternary alloys and MMCs samples were sintered at 600 to 700°C using spark plasma sintering (SPS), with a heating rate of 100°C/minutes, uniaxial pressure of 50 MPa, and a holding time of 10 minutes. Scanning electron microscopy (FE-SEM) was used to exami [...]

Unraveling the Involvement of Serotonergic 5-Hydroxytryptamine Receptor-6 Activation in Chronic Pain: A Narrative Review

Received: 28 September 2024;  Published: 09 April 2025;  doi: 10.21926/obm.neurobiol.2502283

Abstract

Chronic pain is a significant and global healthcare issue that hugely implies the quality of life and productivity of the affected individuals. It is challenging to treat and thus necessitates a deeper understanding of its underlying pathomechanisms to develop targeted interventions. Serotonin is one of the essential neurotransmitters involved in the propagation of pain signals through both ascending and descending pathways, acting via various receptor subtypes, including the 5-hydroxytryptamine receptor-6 (5-HT6R) [...]
