Sampling plans for aphids and their parasitoids in blueberry fields in Argentina
(Taylor & Francis Ltd, 2012-10)
Densities of aphids (Aphis gossypii and A. spiraecola) and mummified aphids at different phenological stages of a blueberry crop were estimated for the purpose of developing sampling plans. Our data set comprised 99 samples ...
Improved signal detection algorithms for unevenly sampled data. Six signals in the radial velocity data for GJ876
(Montlhy Notices of The Royal Society Astronomy, 2014-04-04)
The hunt for Earth analogue planets orbiting Sun-like stars has forced the introduction of
novel methods to detect signals at, or below, the level of the intrinsic noise of the observations.
We present a new global ...
Assessment of the differential linear coherent scattering coefficient of biological samples
(ELSEVIER SCIENCE BV, 2010)
New differential linear coherent scattering coefficient, mu(CS), data for four biological tissue types (fat pork, tendon chicken, adipose and fibroglandular human breast tissues) covering a large momentum transfer interval ...
Estimating sample size of soil cone index profiles by bootstrapping
(Sociedade Brasileira de Ciência do Solo, 2017-11)
Measurements of the soil cone index are widely used to assess soil resistanceto root penetration (SR) and to monitor the soil compaction status of agricultural fields. However, soil sampling for SR estimation is a rather ...
Estimação clássica e bayesiana para relação espécieárea com distribuições truncadas no zero
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Estatística - PPGEs, 2012-03-23)
In ecology, understanding the species-area relationship (SARs) are extremely important to determine species diversity. SARs are fundamental to assess the impact due to the destruction of natural habitats, creation of ...
Diffusion phenomena of the oxygen and nitrogen in niobium by mechanical spectroscopy
(2010-05-19)
The short-range diffusion phenomenon (Snoek Effect) was investigated by mechanical spectroscopy measurements between 300 K and 650 K, in a polycrystalline niobium sample, containing oxygen and nitrogen, using a torsion ...
