Educacão matemática na Internet
(1998) [Journal article]Este trabalho analisa o potencial da internet para a educação matemática. São apontadas características que favorecem a aprendizagem em ambiente de cooperação. Descrições de sites significativos em Educação matemática são ... -
Efeito da estocagem sobre a germinação de Mimosa bimucronata (DC.) OK. e Leucaena leucocephala (Lam.) de Wit
(1980) [Journal article]Seeds of M. bimucronata and L. leucocephala were stored under different conditions: 1. At low temperature (+- 5ºC), with low humidity or in moist sand; 2. At laboraitory, with relative humidity controlled or not. The ... -
Prevalência de fluorose dental em regiões abastecidas com água sem suplementação de flúor no território brasileiro: uma revisão sistemática e metanálise
(2019) [Journal article]Trata-se de uma revisão sistemática e metanálise para estimar e comparar as prevalências de fluorose dental em localidades brasileiras abastecidas com água tratada sem suplementação de flúor e em localidades que utilizam ... -
Brazilian Indian/non-Indian interactions and their effects
(1999) [Journal article]A short review was made of the history of the Brazilian population, starting with the Asians who colonized the region 30,000-40,000 years ago, and continuing with evaluations of the European, African, and neo-Asiatic ... -
Measurement of the attitudes to environment using latent variable models
(1991) [Journal article]This paper shows how to score binary responses to nine items to measure the attitude towards the environment, using a single latent variable for categorical data. This model is a modified version of the logit-probit model ... -
Differential cross section measurements for the production of top quark pairs and of additional jets using dilepton events from pp collisions at √s =13TeV
(2025) [Journal article]Differential cross sections for top quark pair (t¯ t) production are measured in proton-proton collisions at a center-of-mass energy of 13TeV using a sample of events containing two oppositely charged leptons. The data ... -
A new method for reactive constant pH simulations
(2023) [Journal article]We present a simulation method that allows us to calculate the titration curves for systems undergoing protonation/deprotonation reactions—such as charged colloidal suspensions with acidic/basic surface groups, polyelectrolytes, ... -
Search for light long-lived particles decaying to displaced jets in proton–proton collisions at at √𝑠=13.6 TeV
(2025) [Journal article]A search for light long-lived particles (LLPs) decaying to displaced jets is presented, using a data sample of proton–proton collisions at a center-of-mass energy of 13.6 TeV, corresponding to an integrated luminosity of ... -
Vibrational coherences in half-broadband 2D electronic spectroscopy : spectral filtering to identify excited state displacements
(2024) [Journal article]Vibrational coherences in ultrafast pump–probe (PP) and 2D electronic spectroscopy (2DES) provide insights into the excited state dynamics of molecules. Femtosecond coherence spectra and 2D beat maps yield information about ... -
The miniJPAS survey : a preview of the Universe in 56 colors
(2021) [Journal article]The Javalambre-Physics of the Accelerating Universe Astrophysical Survey (J-PAS) will scan thousands of square degrees of the northern sky with a unique set of 56 filters using the dedicated 2.55 m Javalambre Survey Telescope ...
