El conflicto armado es una realidad que vive Colombia desde hace seis décadas y que ha permeado en mayor o menor grado a la familia, a la comunidad, a la sociedad y a la educación. Es así como esta investigación tuvo...

O objetivo deste estudo foi avaliar indicadores da eficiência produtiva de vacas Nelore selecionadas para peso pós-desmama, enfocados nas relações peso bezerro e peso da vaca, nos rebanhos controle (NeC), não-seleci...

O objetivo deste estudo foi avaliar o efeito indireto da seleção para peso pós-desmame sobre medidas corporais e perímetro escrotal de 809 machos Nelore, pertencentes às populações selecionadas (NeS e NeT) e contr...

ABSTRACT The objective of the present study was to evaluate the effects of cooling systems by negative pressure versus directed ducts on the performance of lactating sows and their litter. The experiment was conducted in...

A periodic metagate is designed on top of a boron nitride-graphene heterostructure to modulate the local carrier density distribution on the monolayer graphene. This causes the bandgaps of graphene surface plasmon polari...

Abstract This paper presents an evaluation of multicarrier channel sounding techniques using different random and pseudo-random sequences to modulate the OFDM sounding signal. The Random (Rand), Pseudo-Noise (PN) and Zad...

Transition-metal-doped semiconductor nanocrystals have received significant attention because of their attractive features deeming them invaluable in various technological fields including optoelectronics, bio-photonics,...

Em decorrência da elevada ocorrência (18%) de bezerros Guzerá que não mamaram por conta própria em suas mães (falha na primeira mamada), foram avaliados os fatores associados a estas falhas, sua influência na mort...

AI/ML compute clusters are driving unprecedented bandwidth demands at the package boundary, motivating co-packaged integrated photonics closely co-located with the compute unit. We present a scalable silicon-photonics tr...

Abstract Artificial intelligence (AI) is increasingly used in gastrointestinal endoscopy for polyp detection and classification. However, most AI models are trained on images from multiple video processors, whereas clini...

Graphene has recently emerged as a viable platform for integrated optoelectronic and hybrid photonic devices because of its unique properties. The optical properties of graphene can be dynamically controlled by...

Scattering-type scanning near-field optical microscopy (s-SNOM) and Fourier transform infrared nanospectroscopy (nano-FTIR) are emerging tools for physical and chemical nanocharacterization of organic and inorganic compo...

Abstract Our bone health as an adult is defined by patterns of development in early life, with perturbed growth during fetal and neonatal periods predisposing individuals to poor bone health in adulthood. Studies have id...

Abstract Background In Swaziland, as in many high HIV/TB burden settings, there is not information available regarding the household location of TB cases for identifying areas of increased TB incidence, limiting the deve...

Latin America exhibits one of the highest rates of biodiversity and ecosystem services (ES) loss worldwide along with a remarkable asymmetry in the access to ES benefits (ecosystem services inequality, ESI hereafter). Th...

ABSTRACT An experiment was conducted to evaluate the effect of the intake of a mixture of fish and sacha inchi oils (iOM), organic selenium (iSe), and organic chromium (iCr) on egg production (EP) and feed conversion rat...

Nonradiating sources of energy realized under a wave scattering on high-index dielectric nanoparticles have attracted a lot of attention in nano-optics and nanophotonics. They do not emit energy to the far-field, but si...

Foram utilizadas 65 porcas (Large White x Landrace) com 217,36 ± 21,35 kg para avaliação de diferentes níveis de lisina total (0,950; 1,025; 1,100; 1,175 e 1,250%) na ração para a fase de 21 dias de lactação. Uti...

We report the experimental observation of the periodic switching of topological edge states between two dimerized fs-laser written waveguide arrays. Switching occurs due to the overlap of the modal fields of the edge sta...

The oxidative degradation of Rhodamine B dye under ultraviolet irradiation was studied. The degradation rate was measured with using of smartphone camera. Photocatalytic degradation of the Rhodamine B dye over the P25-Ti...

Bound states in the continuum (BICs) provide exceptional light confinement due to their inherent decoupling from radiative channels. Small symmetry breaking transforms BIC into quasi-BIC (qBIC) that couples to free-space...

The Peer-to-Peer Learning Environment (P2PLE) is a proposed approach to helpinglearners co-construct their learning environment using recommendations aboutpeople, content, and tools. The work draws on current research on...

La colonización rectal por bacterias Gram-negativas productoras de carbapenemasas (CR-BGN-PC) aumenta el riesgo de infecciones invasivas. Se realizó un estudio de casos y controles en un hospital de Santa Fe (Argentina...

Abstract Peatlands are among Earth’s largest terrestrial carbon stores and are crucial for climate regulation, biodiversity conservation, and water security. Yet peatlands worldwide are deteriorating under pressures fr...
