Mathematical modeling of soil and water losses in Oxisol under management systems
Chang, Pablo; Secco, Deonir; Marins, Araceli Ciotti de; Rizzi , Rogério Luis; Tokura, Luciene KazueThe objective of this work was to mathematically model the losses of water and soil in a Oxisol with different management systems, through the physical attributes of soil and vegetation cover. The experimental area was located in the municipality of Santa Tereza do Oeste – PR, in a soybean field. The treatments consisted of three management systems: traditional no-tillage system, plastered no-tillage system, no...
Impact of land cover, slope and precipitation on soil water infiltration
Vidaletti, Vitória Fenilli; Marins, Araceli Ciotti de; Secco, Deonir; Rizzi, Rogério Luís; Chang, PabloThe knowledge of the rate of water infiltration in the soil is of fundamental importance for the proper use and management of the soil, in addition to helping in the planning of irrigation and drainage techniques. Mathematical modeling is indicated as a tool capable of anticipating events and pointing out alternatives that lead to the productive maintenance of the environment, and given the difficulty of obtain...
Aplicação da série de Fourier como análise acústica de instrumentos musicais
Chang, PabloA música sempre fez parte da historia da humanidade, a origem dela foi sensorial e rítmica. Mais tarde, graças a uma organização sistemática e logica dos sons, foram inventadas as notas musicais. Desde séculos, o estudo do som vem ganhado cada vez mais espaço por meio de propriedades físicas das ondas sonoras e teorias matemáticas como, em especial, as series de Fourier. Dessa forma, este trabalho tem por objet...
