Procedimento numérico para análise de vigas de alvenaria estrutural submetidas à flexão simples
(Universidade Estadual Paulista (Unesp), 2010-08-04)
A Engenharia de Estruturas é uma área de grande importância na construção civil, uma vez que sua essência é a otimização de projetos. Para atender essa necessidade, os métodos numéricos são excelentes ferramentas, que ...
DFT theoretical studies of UV-Vis spectra and solvent effects in olefin polymerization catalysts
(Elsevier Science, 2005-01)
DFT theoretical studies of UV-Vis spectra and solvent effects on Cp 2ZrCl2/MAO metallocenic system were performed. The excitation energies have been predicted using the time-dependent density functional theory. Calculations ...
Preparation, characterization and spectroscopy of the europium diphenylphosphinate complex
(1998-07-24)
The purpose of this work is to study the preparation and spectroscopic behavior of the europium diphenylphosphinate complex -Eu(DPP)3. Elemental and thermogravimetric analysis, powder X-ray diffractometry, and infrared ...
Long-term coexistence of two invasive vespid wasps in NW Patagonia (Argentina)
(Springer, 2022-07-03)
In Patagonia (Argentina) two non-native vespid wasps became established in the last decades. Vespula germanica was first detected in 1980, while V. vulgaris arrived some 30 years later. Both species can have a strong ...
A semi-empirical study on the electronic structure of ellipticines
(Elsevier Science BvAmsterdamHolanda, 1999)
Modeling of second-order spectrophotometric data generated by a pH-gradient flow injection technique for the determination of doxorubicin in human plasma
(Elsevier Science, 2013-09)
In this paper, the development of a pH-gradient flow-injection method with diode-array spectrophotometric detection combined with extended multivariate curve resolution–alternating least-squares (MCR–ALS) to quantitate ...
Coseismic slip and early afterslip of the 2015 Illapel, Chile, earthquake: Implications for frictional heterogeneity and coastal uplift
(American Geophysical Union, 2016)
Great subduction earthquakes are thought to rupture portions of the megathrust, where interseismic coupling is high and velocity-weakening frictional behavior is dominant, releasing elastic deformation accrued over a seismic ...
Trophic Relationships among Five Species of Anura in the Colombian Caribbean Tropical Dry Forest: A Spatial and Temporal Approach
(Corporación Universidad de la Costa, 2021)
Space use by foragers consuming renewable resources
(Springer, 2014-05-01)
We study a simple model of a forager as a walk that modifies a relaxing substrate. Within it simplicity, this provides an insight on a number of relevant and non-intuitive facts. Even without memory of the good places to ...
Emotional Categorization of the International Affective Picture System in a Colombian Sample
The International Affective Picture System (IAPS) is a battery of images used to induce discrete emotional reactions. In this study an IAPS subsample of 200 images was analysed to elicit discrete negative emotions and ...
