Present accelerated expansion of the universe from new Weyl-Integrable gravity approach [PDF]

open access: yes, 2014
We investigate if a recently introduced formulation of general relativity on a Weyl-integrable geometry, contains cosmological solutions exhibiting acceleration in the present cosmic expansion. We derive the general conditions to have acceleration in the

INSETICIDAS BOTÂNICOS NO CONTROLE DE FORMIGAS

open access: yesDESAFIOS - Revista Interdisciplinar da Universidade Federal do Tocantins, 2021
As formigas cortadeiras são insetos sociais que apresentam castas reprodutoras e não reprodutoras, vivendo em colônias permanentes. Elas causam grandes prejuízos para plantações desde hortas caseiras a plantios de reflorestamento. Para seu controle é necessário a utilização indiscriminada do controle químico nas o que acaba representando um grande ...

Litter Dynamics and Nutrient Stocks in a Chronosequence of Hyperxerophilous Forest Under the Effect of Clear Felling

open access: yesEcology and Evolution, Volume 15, Issue 10, October 2025.
We investigated litter accumulation and nutrient stocks across a forest regeneration chronosequence in hyperxerophilous Caatinga following clear‐cutting. Using multivariate statistics and structural decomposition indices, we identified functional litter profiles and their association with nutrient cycling and soil resilience. Our findings highlight how
