Abstract Current research of automatic transmission (AT) mainly focuses on the improvement of driving performance, and configuration innovation is one of the main research directions. However, finding new configurations ...

This study presents a novel and high-level anticounterfeiting strategy based on Ce/Yb/Ho triply-doped NaGdF4 nanocrystals with temperature-responsive multicolor emission. A critical factor leading to the multicolor emiss...

Um importante argumento que respalda a histórica dificuldade de funcionamento das emissoras públicas brasileiras está no modelo de gestão que limita os ganhos e os investimentos impactando diretamente na contrataçã...

This review aims to provide an overview over recent developments of light-driven currents with a focus on their application to layered van der Waals materials. In topological and spin-orbit dominated van der Waals materi...

The temperature dependences of the optical absorption edges of Zn doped GaAs semiconductor crystals have been measured from 300 to 560 K. The temperature dependence of the optical absorption in the Urbach edges is adequa...

As a new member of saturable absorber (SA), molybdenum carbide (Mo2C) has some excellent optical properties. Herein, we report a new type of Mo2C/fluorine mica (FM) SA device. Uniform and compact Mo2C films were deposite...

Angioedema is a non-inflammatory edema of the subcutaneous tissue and/or mucosal membranes. It commonly coexists with urticaria and is considered a deep form of urticaria. Less commonly, it occurs as an isolated disease ...

Background The novel coronavirus disease 2019 (COVID-19) pandemic has given rise to fear and panic in the public. Although hospitals in China reduced outpatient visits and restricted inpatient admission to lower the risk...

The body condition index is a measure that attempts to describe energy storage compared to body length. This research was carried out with the aim of obtaining a body condition index in Ctenosaura pectinata. We used 40 a...

The study explores the relationship between foreign exchange reserves (FER) and foreign borrowing (FB) within the framework of the management of capital flows. To investigate this relationship and examine the effect of c...

RESUMO O tamanduá-bandeira (Myrmecophaga tridactyla) e o tamanduá-mirim (Tamandua tetradactyla) são mamíferos xenartros amplamente distribuídos no território nacional. Apesar disso, suas populações estão em cons...

Abstract Myasthenia, a syndrome of impaired neuromuscular transmission, occurs as either an acquired or congenital condition. Myasthenia gravis (MG) is an acquired autoimmune disorder with autoantibodies against the neur...

Resumo Frequentemente, o behaviorismo radical e a análise do comportamento são apresentados na mídia por meio de estereótipos negativos, possivelmente atravancando a difusão de suas propostas aos potenciais benefici...

Organic non-linear optical Benzimidazolium salicylate (BISA) single crystals have been harvested from methanol solution by slow evaporation method. The grown crystals belong to the monoclinic crystal system with space gr...

Thermal camouflage, which is used to conceal objects in the infrared vision for confrontation with infrared detection in civilian or military applications, has garnered increasing attraction and interest recently. Compar...

Abstract Background Cat foods marketed for senior cats (≥7 years) are available to owners. The variability in the nutritional content of these foods is unknown. Objectives To measure the caloric density and caloric d...

Abstract In Brazil, species of the genus Ramphocelus with the presence of various endoparasites have already been reported. Coccidia have been the parasites most frequently found. All species of this genus have similar h...

The characteristics of an overstressed bipolar discharge with a duration of 100-150 ns in argon and air, which was ignited between copper electrodes in argon, and also between an aluminum electrode and a chalcopyrite (Cu...

Resumo Tendo a docência brasileira como objeto de pesquisa, a partir de uma perspectiva histórica, o presente artigo procura responder ao seguinte questionamento: quais práticas podem ser descritas acerca da docência...

Resumo No contexto do Antropoceno, a crise climática revela limitações dos Estados para desenvolver estratégias de mitigação efetivas. Além disso, o aumento da urbanização em nível global trará impactos climá...
