Running of the top quark mass from proton-proton collisions at √s = 13 TeV
(2020) [Journal article]The running of the top quark mass is experimentally investigated for the first time. The mass of the top quark in the modified minimal subtraction (MS¯) renormalization scheme is extracted from a comparison of the differential ... -
Ruprecht 3 : an old star cluster remnant?
(2003) [Journal article]2MASS J and H photometry and integrated spectroscopy are employed to study the nature of the poorly populated compact concentration of stars Ruprecht 3, which was previously catalogued as an open cluster. The integrated ... -
Rupture of a liposomal vesicle
(2004) [Journal article]We discuss pore dynamics in osmotically stressed vesicles. A set of equations which govern the liposomal size, internal solute concentration, and pore diameter is solved numerically. We find that dependent on the internal ... -
O rural agrícola na metrópole : o caso de Porto Alegre, RS
(2018) [Journal article]Os espaços rurais vêm apresentando mudanças significativas nas últimas décadas no Brasil. Neles surgem novas características entre as quais pode-se destacar a extinção dos espaços destinados as práticas agrícolas em razão ... -
Ruralidades na compreensão dos territórios do vinho e sua identidade
(2014) [Journal article]O estudo de questões envolvendo o rural traz à tona a complexidade inerente ao conceito e tratamento do tema, impondo uma cuidadosa observação de suas relações para uma efetiva compreensão.Nesse sentido, o uso das ruralidades ... -
Ruthenium dioxide nanoparticles in ionic liquids : synthesis, caracterization and catalytic properties in hydrogenation of olefins and arenes
(2004) [Journal article]A reação de NaBH4 com RuCl3 dissolvido no líquido iônico 1-n-butil-3-metilimidazólio hexafluorfosfato (BMI.PF6) é um método simples e reprodutível para a síntese de nanopartículas de RuO2 estáveis com distribuição estreita ... -
Saberes construídos e experiências adquiridas no programa de iniciação científica do Colégio Estadual Dom João Becker
(2012) [Journal article]O trabalho investiga o processo de iniciação científica em uma escola pública de Porto Alegre/RS. Este processo ocorre desde 2006 com alunos ingressos no ensino técnico de Química e tem se constituído em um fator de motivação ... -

Safer glycemic control using a fructose-based enteral formula : a randomized crossover clinical trial
(2021) [Journal article]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) [Journal article]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) [Journal article]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) [Journal article]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) [Journal article]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) [Journal article]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) [Journal article]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) [Journal article]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) [Journal article]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) [Journal article]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 ...
