Experimental study of the effect of blade curvature and aspect ratio on the performance of a rotary-wing decelerator
(Elsevier Masson, 2015-05)
The effects of different blade configurations on a vertically falling rotating blade decelerator (pararotor) are studied. A pararotor model equipped with cambered plate blades with different curvatures was tested in a wind ...
The interaction between N-category and N-ratio as a new tool to improve lymph node metastasis staging in gastric cancer: Results of a single cancer center in Brazil
(ELSEVIER SCI LTD, 2011)
Background: Depth of tumor invasion (T-category) and the number of metastatic lymph nodes (N-category) are the most important prognostic factors in patients with gastric cancer. Recently, the ratio between metastatic and ...
The golden ratio in Schwarzschild-Kottler black holes
(The golden ratio in Schwarzschild-Kottler black holes, 2017)
In this paper we show that the golden ratio is present in the Schwarzschild-Kottler metric. For null geodesics with maximal radial acceleration, the turning points of the orbits are in the golden ratio Phi = (root 5 - 1)/2. ...
Analysis of ratio-based responses

Two-degree-of-freedom vortex-induced vibration of circular cylinders with very low aspect ratio and small mass ratio
(London, 2014-02-05)
The investigation of vortex-induced vibration on very short cylinders with two degrees of freedom has drawn the attention of a large number of researchers. Some investigations on such a problem are carried out in order to ...
Sex-specific costs of rearing a nestling and its implications in the brood sex ratio of Magellanic penguins
(Springer, 2021-08)
In birds, possible explanations for a bias in brood sex ratio include differential cost of rearing nestlings of different sexes, and different parental fitness returns related to offspring sex. We studied brood sex ratio ...
In situ determination of the syringyl/guaiacyl ratio of residual lignin in pre-bleached eucalypt kraft pulps by analytical pyrolysis
(Journal of Analytical and Applied Pyrolysis, 2019)
Go/N ratio in tropical soils from Brazil
(2015-01-01)
The geotechnical behavior of tropical soils is complex and cannot be supported only by the classical soil mechanics. The Standard Penetration Test (SPT) is broadly used for geotechnical site characterization. However, it ...
Human genetic studies in areas of high natural radiation. IX. Effects on mortality, morbidity and sex ratio

Use of otolith strontium:calcium ratio as indicator of seasonal displacements of the silverside (Odontesthes bonariensis) in a freshwater-marine environment
(Csiro Publishing, 2013-04)
Strontium:calcium ratios were measured in sagittal otoliths of silverside (Odontesthes bonariensis) from a freshwater-marine environment (Paraná River Delta and River de la Plata River, South America) in order to understand ...
