Abstract Current paradigms for the origin and evolutions of life and the environment on early Earth have been based on the premises that carbon dioxide (CO2) and nitrogen gas (N2) were the principal constituents of the a...

RESUMO Foram estudados diferentes diluentes no processo de refrigeração do sêmen da garoupa-verdadeira. Inicialmente, a taxa e a duração da motilidade e a concentração espermática foram avaliadas, caracterizando ...

Abstract. Range spread-F (RSF) and occurrence of "satellite" traces prior to RSF onset were studied at the southern peak of the ionospheric equatorial anomaly (EA). Ionograms recorded in September 2007 at the new ionosph...

We present a vectorial optical field (VOF) framework that surpasses the diffraction limit in both long-range imaging and energy delivery. By jointly engineering spatial and temporal dimensions, reflective Fourier ptychog...

Abstract Groundwater is a central component of the Earth system. However, our understanding of how it is dynamically interlinked with the atmosphere, hydrosphere, cryosphere, biosphere, geosphere, and anthroposphere rema...

In this work, the amorphous alloys Co₆₉Nb₂₃B₈, Fe₇₈Si₉B₁₃, Co₆₈Cu₂₃B₉, and Fe₆₄Nb₂₈B₈ were synthesized by high-energy mechanical milling (HEM) and investigated as promising biomate...

Background: This research is motivated by the gap between the importance of learning Arabic and the difficulties faced by students in learning Nahwu through the Al-Jurumiyah textbook. Purpose To determine the applicati...

O produto mais importante do conhecimento é a ignorância. A situação sugere a imagem de alguém que vive numa ilha de conhecimento cercado por um mar de ignorância. Quando a área dessa ilha aumenta pelo progresso d...

Abstract Objective To investigate the application effect of 3D printing combined with MR technology in teaching the percutaneous screw fixation of scaphoid fractures under C-arm fluoroscopy, providing new ideas to enhanc...

Abstract Mosses and lichens are effective bioindicators because they absorb nutrients and pollutants directly from the atmosphere, allowing them to accumulate metals and nutrients. This study evaluated mosses and lichens...

CO₂ emissions are a critical environmental concern driving global climate change, particularly the rise in Earth's average temperatures. Therefore, reducing CO₂ release into the atmosphere is essential. One promising...

The management of rock wool waste poses a growing challenge, with global production exceeding 2.5 million tons annually. Thermal inertization converts this fibrous hazardous waste into safe glassy products; however, high...

Abstract Air pollution is a major environmental and public health challenge in Greater Cairo due to rapid urbanization, intense traffic activity, and recurrent regional dust intrusions. This study presents a data driven ...

The article highlights the importance of a supportive family environment in preparing children for physical education and sports activities. It argues for the significance of instilling health-preserving skills in childr...

Airlines release the unburned jet fuel into the atmosphere to reduce the weight of aircraft before landing. Sometimes, aircraft reach a weight more than takeoff weight while departing from the airport. Therefore, the pil...

The ionosphere´s long-term trends have been studied since 1989, with a particular focus on the F2 region´s parameters due to their importance in space weather and radio signal propagation research. The accuracy and att...

Reactions of cerium/praseodymium oxides under hydrogen atmospheres, and subsequently, carbon dioxide, involved in chemical looping reverse water–gas shift cycles (RWGS) at 500 ◦C were investigated by in-situ high- te...

Deactivation and regeneration of Pt/Al2O3 catalysts during the hydrodechlorination of carbon tetrachloride were studied. The effect of reactant partial pressures and temperature on the catalyst deactivation was investiga...

Abstract Assessment of the toxicity of insoluble particulate matter (PM) in the atmosphere is crucially important. However, because of challenges associated with extracting insoluble PM from filters, the toxicity of inso...

O entendimento das mudanças em paisagens amazônicas depende de documentação das alterações na cobertura da terra. Este artigo parte de resultados do Experimento de Larga Escala de Biosfera-Atmosfera na Amazônia (L...

Los bosques tropicales almacenan grandes cantidades de carbono en su biomasa, y por ello juegan un papel determinante en el ciclo global de este elemento. Las variables biofísicas determinan la capacidad de almacenamien...

Fundamental absorption edge of (Y0.06Ga0.94)2O3 thin films, obtained by radio-frequency ion-plasmous sputtering, was investigated using the method of optical spectroscopy. It was established that these films are formed i...
