Efeitos da radiação eletromagnética laser em Diaphorina citri effects of Laser electromagnetic radiation on Diaphorina citri. Os níveis que a humanidade chegou no uso de pesticidas alarma os órgãos internacionais de controle da saúde coletiva, especialmente no Brasil. À toxicidade ambiental que aumenta, não corresponde um av... ... Repository: BDPA Publication year: 2019
In-operando analysis of the corrosion patterns and rates under magnetic fields using metallic film. Magnets, or electromagnets, are common components in everyday appliances and are widely used in medicine, industries,transportation, and electrical power systems. It is known that the magnetic field (... ... Repository: BDPA Publication year: 2022
Monitoramento e predição de desordem fisiológica em mangas produzidas no Vale do São Francisco com o uso da espectroscopia. Segundo este estudo, o espectro eletromagnético na faixa entre 550 nm e 650 nm pode ser utilizado para diferenciar, de forma não destrutiva, frutos saudáveis de fruto suscetíveis ao corte negro, tanto... ...

Finding suitable transect spacing and sampling designs for accurate soil ECa mapping from EM38-MK2. Finding an ideal sampling design is a crucial stage in detailed soil mapping to assure reasonable accuracy of resulting soil property maps. This study aimed to evaluate the influence of sampling desig... ... Repository: BDPA Publication year: 2020
Identifying soil horizons transitions for ground-truthing and interpreting ground penetrating radar (GPR) imagery of Planosols. The Ground Penetrating Radar (GPR) has potential to characterize soils both vertically and horizontally. The effectiveness of using GPR relies on the interpretation of soil targets in the radargrams.... ... Repository: BDPA Publication year: 2023
