Weed interference in the initial growth of meristem-grown sugarcane plantlets
(Univ Federal Campina Grande, 2018-09-01)
The use of new systems of sugarcane planting such as Plene (TM), Plene Evolve (TM), Plene PB (TM) and AgMusa (TM) requires specific studies on the initial interference of weed in the sugarcane crop. Me objective of this ...
Theory of non-steady state electrical characteristics of metal-insulator-metal structures with schottky barriers and exponentially distributed impurity states
(1996-12-01)
We discuss non-steady state electrical characteristics of a metal-insulator-metal structure. We consider an exponential distribution (in energy) of impurity states in addition to impurity states at a single energy level ...

Spatial distribution of runoff depth from a watershed located in a cuesta relief area of São Paulo State, Brazil
(2014)
This study was undertaken in a 1566 ha drainage basin situated in an area with cuesta relief in the state of São Paulo, Brazil. The objectives were: 1) to map the maximum potential soil water retention capacity, and 2) to ...
Generation of mineral density distribution maps from subject-specific models of mandibles - a preliminary study
(WILEY-BLACKWELL, 2012)
Background Determination of the mineral content of bone and its distribution by computed tomography (CT) enables one to define the insertion points for prosthetic devices, or determine the degree of healing in cases of ...
Nitrogen fertilization, plant density and maize yield cropped under no-tillage systemFertilização nitrogenada, densidade de plantas e rendimento de milho cultivado no sistema plantio direto
(2011-01-01)
In maize (Zea mays L.), the inadequate nitrogen supply and planting density are considered limiting factors to the grain yield. The objective of this study was to evaluate the influence of different nitrogen levels and ...
Sistema radicular do Panicum maximum Jacq. cv. IPR-86 Milênio adubado com nitrogênio e submetido à lotação rotacionada
(Sociedade Brasileira de Zootecnia, 2008)
Avaliou-se o efeito do nitrogênio no sistema radicular da espécie Panicum maximum Jacq. cv. IPR-86 Milênio, sob pastejo. As doses de N utilizadas foram 0; 150; 300 e 450 kg/ha.ano. As densidades de raízes no pré-pastejo ...
