On the time-averaging of ultrafine particle number size spectra in vehicular plumes

The probability of attending school four our group of interest in this region increased by 6.5 percentage points after the expansion of the Bolsa Família program in 2007 and

The direct consequences arise from the physical properties of the pigment (particle size and particle size distribution, surface area) and from the chemical properties

O método de comparação é um complemento imprescindível do método residual, complementaridade que no caso do residual dinâmico estende-se não só às análises

Tabela 2.2: Classificação de risco dos agrotóxicos pela OMS (Fonte: WHO 2010).. situação de vulnerabilidade os ecossistemas aquáticos, uma vez que os contaminantes

The particle size distribution fluctuated substantially during daytime (Fig. 1) but at night time there were periods without fluctuations. For these night time periods, the

The diameter of the balls used in the milling of shrimp shells can decisively influence the particle size distribution of the material, directly affecting the size distribution

The investigation focused on pH changes, the molar ratio of Ca/P, morphology, particle size, particle size distribution, zeta potential, and chemical bonding to demonstrate

Current assay therefore evaluates the types of material for the conditioning of samples in the rumen of animals, particle size and incubation time on the estimates of
