Genotypic Differences among Argentinean Maize Hybrids in Yield Response to Stand Density
(Amer Soc Agronomy, 2014-10)
Maize (Zea mays L.) stand density selection is an important management practice because yield is maximized at a particularoptimum value. Optimum stand density (OSD) varies across environments, and many have argued that ...
Nasopharyngeal Pneumococcal Density Is Associated With Viral Activity but Not With Use of Improved Stoves Among Young Andean Children
(Oxford University Press, 2017)
BACKGROUND: Indoor smoke exposure is common in developing countries and may influence nasopharyngeal (NP) pneumococcal colonization density and risk of acute respiratory illness. We compared colonization density among ...
Calculation of the statistical properties in intermittency using the natural invariant density
(Multidisciplinary Digital Publishing Institute, 2021-06)
We use the natural invariant density of the map and the Perron–Frobenius operator to analytically evaluate the statistical properties for chaotic intermittency. This study can be understood as an improvement of the previous ...
Maize stand density yield response of parental inbred lines and derived hybrids
(Crop Science Society of America, 2017-01)
Maize (Zea mays L.) grain yield has a parabolic response to stand density changes, creating an optimum stand density that maximizes yield. Argentinean commercial hybrids differ in their optimum stand density when grown at ...
Improved electron density measurements at Jicamarca
(American Geophysical Union, 2007-11-27)
Taking into account the effects of electron Coulomb collisions, incoherent scatter (IS) radar cross sections for probing angles close to perpendicular to the magnetic field have been calculated and used to correct backscattered ...
Diurnal evolution of the F region electron density local time gradient at low and middle latitudes resolved by the Swarm constellation
(American Geophysical Union, 2016-09-02)
In this study we have provided new insights into the local time gradient of F region electron density (ΔNe) derived from the lower pair of Swarm satellites flying side by side. Our result shows that the electron density ...
Impacts of honeybee density on crop yield: A meta-analysis
(Wiley Blackwell Publishing, Inc, 2019-02-03)
1. There is increasing recognition that pollination deficits are limiting crop yields world-wide. However, management strategies for optimal insect pollination are still unclear for most crops. Current management focuses ...
Experimental field test of spatial variation in rodent predation of nuts relative to distance and seed density
(Springer, 2010-06)
The spatial context in which seed predation occurs may modify the spatial structure of recruitment generated by seed dispersal. The Janzen-Connell (J-C) model predicts that granivores will exert greater pressure on ...
Inferring E region electron density profiles at Jicamarca from Faraday rotation of coherent scatter
(American Geophysical Union, 2001-12-01)
A new technique for measuring E region plasma density profiles in the equatorial electrojet using a bistatic coherent scatter radar is described. The technique utilizes the Faraday rotation of the obliquely and coherently ...
Broad snouted caiman (Caiman latirostris) growth under different rearing densities
(Elsevier Science, 2008-04)
The effect of density on growth in body mass (BM) and total length (TL) of Caiman latirostris hatchlings raised in small pens (area 0.36 m2), for 3 months, was investigated. Twelve animals from each of three clutches were ...
