SPATIALLY VARIABLE RIPPLE AND GROOVE FORMATION ON GALLIUM ARSENIDE USING LINEAR, RADIAL, AND AZIMUTHAL POLARIZATIONS OF LASER BEAM

Spatially Variable Ripple and Groove Formation on Gallium Arsenide Using Linear, Radial, and Azimuthal Polarizations of Laser Beam

We demonstrated the linear, radial, and annular ripple formation on the surface of GaAs.The ESSIAC POWDER formation of linear ripples was optimized by the number of shots and the fluence of 30 ps, 532 nm pulses.The radial and annular nanoripples were produced under the ablation using doughnut-like beams possessing azimuthal and radial polarizations

Periurbanization and conservation pressures over remnants of native vegetation: impact on ecosystem services for a Latin-American capital city

Urban expansion in Latin-American cities is faster than urban planning.In order to implement sustainable planning the capacity of peri-urban areas to provide ecosystem services must be evaluated in the context of competing urbanization and conservation pressures.In this study we analyzed the effect of urban expansion on peri-urban vegetation of the

Accounting for reciprocity in negotiation and social exchange

People generally adhere to the norm of reciprocity during both tacit and negotiated exchange.Emotional responses generated from profitable and unprofitable exchange facilitate the formation of motives to settle scores RAW CHLORELLA POWDER with others.In two studies we examine how exchange incidents trigger positive and negative emotional responses,
