Abstract The formation of a precursor film (PF) is always coupled with better wettability; thus, clarifying the formation mechanism is required to optimize the interfacial structures. However, recent research focuses on ...

Mineral-associated organic matter, the dominant form of relatively stable carbon (C) in soil, often co-occurs with reactive iron (Fe) and aluminum (Al) phases across soils. Yet, how organo-metallic associations at the mo...

Se describe en detalle un nuevo estípite petrificado de Millerocaulis Erasmus ex Tidwell emend. Vera, colectado en afloramientos de edad aptiana de la Formación Cerro Negro en Isla Livingston (Antártida). Este espéci...

ABSTRACT Understanding how skeletal muscle influences bone formation is essential for uncovering the mechanisms of muscle‐bone communication and developing therapies for osteoporosis. Here, we demonstrate that extracel...

The Early Cretaceous Zubair Formation is a key clastic reservoir in southern  Iraq, but reservoir quality varies laterally between major fields. To evaluate  and compare Zubair Formation petrophysical properties in the...

It has investigated using a Clark-type oxygen electrode and an ESR method that the conformation of thiol-compounds such as cysteine (Cys) and glutathione (GSH) effects on the formation of a nitrosyl(protoporphyrinato)iro...

Résumé Les questions concernant les relations entre recherche et formation demeurent un enjeu majeur dans la formation des enseignant·e·s. Afin de réfléchir aux apports de la recherche, nous avons analysé les lien...

This paper offers a critique on state formation theories used in the explanation of the rise of the biblical United Monarchy. The last three decades of archaeological and biblical research have shown that there is no fir...

This study reports LA-ICP-MS U–Pb ages and Lu–Hf isotope data of detrital zircons from sedimentary rocks of the Nanduan Formation in the Changning–Menglian tectonic belt. The U–Pb age spectra display three domina...

Six productive samples from the upper part of the Early Carboniferous Ambo Formation at Pongo de Mainique, Peru, are analyzed for 55 recognized miospore species of continental origin. One new morphospecies, Cristatispori...

New findings of early vertebrates, including placoderms, sarcopterygians, and the galeaspids Sanqiaspis rostrata, Macrothyraspis longicornis, Gantarostraspis gengi, Wenshanaspis sp., are described from Posongchong Format...

ObjectiveTo understand the influence of cultivation conditions on the formation of Salmonella biofilm and provide basis for ensure food safety.MethodsCongo red staining and crystal violet staining method were used to scr...

To induce new bone formation, mesenchymal stem cells were seeded onto atelocollagen honeycomb scaffold. We evaluated the efficacy of this scaffold combined with KUSA/A1 cells in vivo. KUSA/A1 cells alone and with ateloco...

Ride-pooling has the potential to offer a sustainable solution for urban mobility by reducing vehicle use and emissions through shared trips. However, its adoption remains limited due to poor matching performance. Many r...

Abstract Background Diffuse large B-cell lymphoma (DLBCL) exhibits significant heterogeneity, with therapy resistance in Activated B-cell-like (ABC) and relapsed Germinal Center B-cell-like (GCB) subtypes being major cha...

Abstract The kinetics of formation of chromium(III)–iminodiacetic acid complex have been studied spectrophotometrically in the temperature range 35–55 °C. The reaction is first order with respect to chromium(III) an...

The article provides a scientific and applied substantiation for improving the modeling of the processes of formation and realization of the potential of high-technology startups in the ICT sector through the approbation...

This work investigates the relevance of analogy, metonymy and metaphor in word formation patterns and their products. Initially, the semantic side of proportional analogy in morphological restructuring is analyzed. The w...

Being the main oil-bearing basin of Argentina, the Neuquén Basin contains a well-documented stratigraphic record of continental and marine sedimentation during the Jurassic and Cretaceous in the western margin of Gondwa...

The article analyzes the contribution of occasional word formation to the expressiveness of the text. Making the text more expressive by means of an occasional word-formation takes place when the process of text creatio...

The issues of stability / instability of modern society and the state, factors of overcoming destructive phenomena are considered. Among the most important factors, the excessive growth of uncertainty, polyvariance, rand...

Phase equilibria of the quasi-ternary systems Ag2S–BIVS2–CV2S3 (BIV– Ge, Sn; CV–As, Sb) were investigated using phase analysis based on XRD. Isothermal sections at 500 Kand glass formation regions in the respecti...

Multiple studies had been conducted to improve the geological understanding and enrichment patterns of the Wufeng-Longmaxi Formation in the southeastern Sichuan Basin’s complex tectonic belt. However, the influence of ...

Studies of the palaeobiology of titanosaur eggs are significantly more common than studies of titanosaur-egg-bearing strata. Nevertheless, the latter provide significant insight into palaeoenvironmental conditions associ...
