A Model for Induction Motors with Non-Uniform Air-Gap
(Planta Piloto de Ingeniería Química, 2005-12)
Equations to calculate inductances of induction motors, considering non-uniform air-gap, are proposed. The analyzed air-gap variations are static and dynamic eccentricity and stator slots. The equations for inductance ...
Atmospheric and altitude correction methods for air gaps and clean insulators-corrections for short gaps under DC and application difficulties
(CIGRE, 2018-02)
The dielectric strength of air gaps is affected by air density, humidity and temperature. In order to normalize external insulation strength of power equipment under different conditions, such effects need to be taken into ...
Gender Wage Gap in female industrial workers in Buenos Aires (1903-1942)Las trabajadoras industriales de Buenos Aires y la desigualdad salarial de género (1903-1942): Nuevos datos y una agenda de investigación
(Cambridge University Press, 2021-01)
There is a great advance in research on the measure, causes and consequences of inequality: wage inequality has received attention for its implications, in relation to economic policies, growth and development. This article ...
Application of an Additional Excitation in Inverter-Fed Induction Motors for Air-Gap Eccentricity Diagnosis
(Institute of Electrical and Electronics Engineers, 2006-12)
In this paper, the application of an additional excitation in induction motor (IM) drives for static, dynamic, and mixed eccentricity diagnosis is proposed. The additional excitation consists in a predefined inverter-switching ...
Effects of canopy gaps on the microclimate, seedling establishment, growth and survival in a Nothofagus betuloides dominated forest in Tierra del Fuego, Chile
(2013)
In Nothofagus betuloides dominated forests in Tierra del Fuego canopy gaps, regeneration
wave systems, partial mortality and blow-downs have been documented. The objective
was to analyse the effects of naturally created ...
GAPS-megacities: A new global platform for investigating persistent organic pollutants and chemicals of emerging concern in urban air
(Elsevier, 2020-12)
A pilot study was initiated in 2018 under the Global Atmospheric Passive Sampling (GAPS) Network named GAPS-Megacities. This study included 20 megacities/major cities across the globe with the goal of better understanding ...
Cambios de usos del suelo en la periferia del área metropolitana de Buenos Aires: Aportes para una teoría de la rent gap periurbanaChanges in land use in the periphery of Buenos Aires metropolitan area: Contributions to a peri-urban rent gap theory
(Universidad Nacional de La Plata. Facultad de Humanidades y Ciencias de la Educación, 2021-05-03)
Desde mediados de la década del 1990 se observa una fuerte expansión de urbanizaciones cerradas en las periferias metropolitanas de Buenos Aires, que avanzan sobre áreas ambientalmente frágiles, como humedales y suelos ...
