Safer glycemic control using a fructose-based enteral formula : a randomized crossover clinical trial
(2021) [Artigo de periódico]Introduction: Glycemic variability during nutritional therapy in critically ill patients is associated with morbidity and mortality. A low-carbohydrate diet can be help avoid glycemic oscillation in patients under enteral ... -
SafeSmart : a VANET system for faster responses and increased safety in time-critical scenarios
(2021) [Artigo de periódico]An important use case for Vehicular Ad-hoc Networks (VANETs) is its application in the warning systems of emergency vehicles (EV). VANET-based vehicle-to-infrastructure (V2I) communication can be used to exchange important ... -
Saias e blusas : invenções para aprender a multiplicar com a matemática moderna
(2019) [Artigo de periódico]O artigo apresenta uma investigação sobre uma experiência de inovação de ensino de matemática registrada em um caderno de uma aluna que frequentou o segundo ano do curso primário do Instituto de Educação General Flores da ... -
Sala de aula invertida (flipped classroom) : inovando as aulas de física
(2016) [Artigo de periódico]Aulas puramente expositivas, com alunos passivos e comumente inibidos a qualquer ação interativa. Esse retrato do ensino tradicional diverge do perfil dos alunos atuais, os quais, em sua maioria, estão constantemente ... -
Sample of minor merger of galaxies : II. Modelling HII region properties
(2008) [Artigo de periódico]Context. Studies of interacting galaxies have shown that dwarf galaxies may be produced in tidal tails during collisions. Numerical simulations suggest that the total detachment of the tidal dwarf requires the companion’s ... -
Sample of minor merger of galaxies : optical CCD surface photometry and HII region properties
(2004) [Artigo de periódico]We present the results of the B, V and I photometry of eleven southern minor mergers. The total apparent B magnitude, integrated B − V and V − I colours were measured. We built B, V, and I equivalent profiles for each ... -
Sample preparation strategies for petroleum cokedigestion and further cerium and lanthanumdetermination by DSN-ICP-OES
(2018) [Artigo de periódico]The determination of cerium and lanthanum in petroleum coke samples by inductively coupled plasmaoptical emission spectrometry coupled to a desolvating nebulizer system (DSN-ICP-OES) is proposed forthefirst time after ... -

Saturating field configurations for the massless thirring-wess model
(1979) [Artigo de periódico]The saturation of the massless Thirring-Wess model by induced field configurations is presented. The limiting procedure connecting the massless Thirring-Wess model arith the Schwinger model is reexamined. Special emphasis ... -
Saturation of the massive Schwinger model
(1980) [Artigo de periódico]We determine the field configurations saturating the massive Schwinger model (MSM). Fermion confinement is proved, for the MSM, without invoking the Bose form of the theory. A gas of induced instantons accounts for the ... -
Saturation physics at HERA and RHIC : an unified description
(2006) [Artigo de periódico]One of the frontiers of QCD which are intensely investigated in high energy experiments is the high energy (small x) regime, where we expect to observe the non-linear behavior of the theory. In this regime, the growth of ... -

Scaling laws for breathing frequencies of solitary modes in the Zakharov equations
(2002) [Artigo de periódico]We analyze typical time scales resulting from the coupled dynamics of high- and low-frequency wave components in solitary solutions of the Zakharov equations. Linear stability analysis around the solitary modes suggests ... -
Scaling violation and shadowing corrections at HERA
(1999) [Artigo de periódico]We study the value of shadowing corrections (SC) in the HERA kinematic region in the Glauber{ Mueller approach. Since the Glauber{Mueller approach was proven in perturbative quantum chromodynamics (QCD) in the double-logarithmic ... -
Sc and neutron-capture abundances in Galactic low- and high-α field halo stars
(2017) [Artigo de periódico]We determine relative abundance ratios for the neutron-capture elements Zr, La, Ce, Nd and Eu for a sample of 27 Galactic dwarf stars with −1.5 < [Fe/H] < −0.8. We also measure the iron-peak element Sc. These stars separate ... -
Scanning electron microscopy and machine learning reveal heterogeneity in capsular morphotypes of the human pathogen Cryptococcus spp.
(2020) [Artigo de periódico]Phenotypic heterogeneity is an important trait for the development and survival of many microorganisms including the yeast Cryptococcus spp., a deadly pathogen spread worldwide. Here, we have applied scanning electron ... -
Scattering studies with low-energy kaon-proton femtoscopy in proton-proton collisions at the LHC
(2020) [Artigo de periódico]The study of the strength and behavior of the antikaon-nucleon (¯KN) interaction constitutes one of the key focuses of the strangeness sector in low-energy quantum chromodynamics (QCD). In this Letter a unique high-precision ... -
Schema evolution in the star framework
(1998) [Artigo de periódico]The STAR data model supports the definition of object schemata, according either to some design methodology or to the designer's decision. Object schemata allow a flexible management of the various representations that are ... -
Scientometric indicators for Brazilian research on High Energy Physics, 1983-2013
(2017) [Artigo de periódico]This article presents an analysis of Brazilian research on High Energy Physics (HEP) indexed by Web of Science (WoS) from 1983 to 2013. Scientometric indicators for output, collaboration and impact were used to characterize ...
