Advancements in Ni‐based Catalysts for Direct Urea Fuel Cells: A Comprehensive Review

Abstract The growing demand for sustainable energy sources has spurred significant studies to optimize the potency of fuel cell technology. Direct urea fuel cell (DUFC) has gained attention due to their energy density, eco‐friendliness, and...

New detection technologies for ultra-high energy cosmic rays and neutrinos

Even with an accumulated data set from an integrated six years of lifetime from the Auger experiment, no point sources of charged cosmic rays have be identified at the highest energies. Significantly increased apertures such as promised by ...

A Contactless Coupled Pendulum and Piezoelectric Wave Energy Harvester: Model and Experiment

Wireless monitoring systems for the marine environment are important for rapidly growing subsea developments. The power supply of wireless sensor nodes within the monitoring systems, however, is a major challenge. This study proposes a nove...

Submesoscale‐Permitting Physical/Biogeochemical Future Projections for the Main Hawaiian Islands

Abstract Global climate models provide useful tools to forecast large‐scale anthropogenic trends and the impacts on ocean physics and marine biology and chemistry. Due to coarse spatial resolution, they typically lack the ability to represe...

Filling the Gap of Meteorological Data Along the Prut River Valley, Romania - Cârja Experimental Weather Station (2013-2020)

The study presents the results of the measurement realized at a meteorological weather station installed in Cârja village, situated in the valley of Prut river in the south-eastern tip of Vaslui county, Romania. The observations cover the i...

Can resistant coral-Symbiodinium associations enable coral communities to survive climate change? A study of a site exposed to long-term hot water input

Climate change has led to a decline in the health of corals and coral reefs around the world. Studies have shown that, while some corals can cope with natural and anthropogenic stressors either through resistance mechanisms of coral hosts o...

The crowns have eyes: multiple opsins found in the eyes of the crown-of-thorns starfish Acanthaster planci

Abstract Background Opsins are G protein-coupled receptors used for both visual and non-visual photoreception, and these proteins evolutionarily date back to the base of the bilaterians. In the current sequencing age, phylogenomic analysis ...

Editorial: Programmed cell death in aquatic animals

Journalisters syn på journalistisk etik

Ethics, moral and values have gained much attention in the past decades, which also have created focus on journalism ethics, particularly because of the power and potentially negative consequences journalism can have. A survey with members ...

The Small Motherland as a Sociological Category: Reflections on the Book — Boronoev A.O., Tkhakakov V.Kh., Mironov D.V. The Phenomenon of a Small Homeland and the Problems of Constructing a Civic Identity. St Petersburg: Asterion publ., 2024

This new book by St. Petersburg sociologists translates the concept of a small homeland, which is popular in journalism, local history and pedagogy, into a sociological category, which provides an impetus for methodological reflections on i...

Multiple organ failure in the newborn: the point of view of the pathologist

One of the most severe events occurring in critically ill patients admitted to a neonatal intensive care unit (NICU) center is represented by the multiple organ failure (MOF), a systemic inflammatory response leading to a progressive organ ...

Sufis and Women: The Study of Women's Sufis in The Western World

The lack of records about the involvement and contribution of women in Sufism texts cannot be used as an excuse that women have a small role and position in the development and dissemination of Sufism teachings, doctrines and practices. So ...

“Regionalization” of Global Value Chains: Off-Shoring or Re-Shoring?

The article examines the evolution of theoretical ideas about the regionalization of production activities of global value chains (GVCs). The paper reveals the division of “factory” and “headquarters” economies, which triggered the creation...

On Security and Throughput for Energy Harvesting Untrusted Relays in IoT Systems Using NOMA

In this paper, we analyze the secrecy and throughput of multiple-input single-output (MISO) energy harvesting (EH) Internet of Things (IoT) systems, in which a multi-antenna base station (BS) transmits signals to IoT devices (IoTDs) with th...

Online Classification of Road Roughness Conditions with Vehicle Unsprung Mass Acceleration by Sliding Time Window

Suspension control systems are in need for more information of road roughness conditions to improve their performance under different roads. Existing methods of gauging road roughness are limited, and they usually involve visual inspections...

Artificial Neural Networks with Machine Learning Design for a Polyphasic Encoder

Artificial neural networks are a powerful tool for managing data that are difficult to process and interpret. This article presents the design and implementation of backpropagated multilayer artificial neural networks, structured with a vec...

Domestic Organic Rankine Cycle-Based Cogeneration Systems as a Way to Reduce Dust Emissions in Municipal Heating

Environmental issues are nowadays of great importance. In particular air and water quality should be kept at as high levels as possible. Energy conversion systems and devices which are applied for converting the chemical energy contained in...

Optimal Selection of Conductors in Distribution System Designs Using Multi-Criteria Decision
