Povo negro

Revista Eclesiástica Brasileira, 1986
O VI Intereclesial esteve marcado pela presença, senão majoritária, de uma grande maioria caracterizada pela comunidade negra. De Norte a Sul, Leste a Oeste estiveram presentes os sinais visíveis da negritude que fortalece o avanço sem limites das Comunidades Eclesiais de Base, entre os pobres...

Jornal “O povo”:

Semina - Revista dos Pós-Graduandos em História da UPF, 2023
O presente trabalho tem por objetivo construir uma análise histórica em torno do jornal “O povo”, periódico que circulou semanalmente na região do Seridó Potiguar, sertão centro-sul do estado do Rio Grande do Norte, entre os anos de 1889 e 1892. Inserido em um contexto de transição entre o fim do período imperial e a instituição do sistema republicano ...

Vibrational Signals for Mating Disruption Do Not Negatively Affect Grapevine Growth and Production

Australian Journal of Grape and Wine Research, Volume 2026, Issue 1, 2026.
Vibrational mating disruption (VMD) is a promising strategy to control Scaphoideus titanus populations in vineyards, and it is based on the prolonged application of a species‐specific disturbance vibrational signal (DVS) on grapevines. Plants can react by different transcriptional, physiological, and morphological changes, according to the source and ...

Exploring the evolution of active sites on Fe2GeO4–Ni3Ge2O5(OH)4 interfaces for water oxidation

InfoMat, Volume 7, Issue 12, December 2025.
Producing clean fuels from water requires a sluggish step called the oxygen evolution reaction. Guided by computational studies, we synthesized a new material where iron and nickel work together in a special way, helping this step happen faster and using less energy.

Unfolding Thermodynamics of Cysteine-Rich Proteins and Molecular Thermal-Adaptation of Marine Ciliates

Biomolecules, 2013
Euplotes nobilii and Euplotes raikovi are phylogenetically closely allied species of marine ciliates, living in polar and temperate waters, respectively. Their evolutional relation and the sharply different temperatures of their natural environments make

Improved Torsion Pendulum for Ground Testing of LISA Displacement Sensors

, 2004
We discuss a new torsion pendulum design for ground testing of prototype LISA (Laser Interferometer Space Antenna) displacement sensors. This new design is directly sensitive to net forces and therefore provides a more representative test of the noisy ...

Nonlinear Distortion Equalization in Multi‐Span Optical Links Via a Feed‐Forward Photonic Neural Network

Laser &Photonics Reviews, Volume 19, Issue 23, December 3, 2025.
A feed‐forward photonic neural network equalizes linear and nonlinear impairments in multi‐span IMDD optical fiber transmission. The linear processing stage employs an 8‐tap optical Finite Impulse Response filter integrated on a silicon photonics platform, while the end‐of‐line photodetector represents the nonlinear stage.

Dynamical two-mode squeezing of thermal fluctuations in a cavity opto-mechanical system

, 2015
We report the experimental observation of two-mode squeezing in the oscillation quadratures of a thermal micro-oscillator. This effect is obtained by parametric modulation of the optical spring in a cavity opto-mechanical system.

Portugal: Political Developments and Data in 2024

European Journal of Political Research Political Data Yearbook, Volume 64, Issue 1, Page 509-531, December 2025.
Abstract On 25 April 2024, Portugal celebrated the 50th anniversary of the Portuguese Revolution of Carnations, which led to the establishment of democracy in the country. Commemorations took place throughout the year. Moreover, it was a super year of legislative elections and subnational elections in the Azores and Madeira. On top of the national‐ and
