Diagnóstico escintigráfico del reflujo gastroesofágico en el niño
Partimos del hecho de que la patología cardioesofágica en el niño se considera como una “patología del desarrollo”, presentando unas características especiales diferentes a las del adulto, por lo que su clínica, diagnóstico y tratamiento van a tener unos patrones específicos en relación a los que …

Eastern Tropical Pacific Climate And El Niño Variability During The Past Millennium
<p>The El Niño Southern Oscillation (ENSO) has been implicated in large-scale climate shifts of the past millennia, but paleoclimate records from the dynamically vital eastern equatorial Pacific Ocean (EEP) spanning the past millennium are sparse. This has limited our understanding of tropical …

The El Niño - Southern Oscillation, rainfall and wheat yields in South Africa
This thesis assesses the relationships between the El Niño-Southern Oscillation (ENSO), rainfall and South African commercial winter wheat yields from 1974 - 2000. The analysis is through a combination of the Pearson's product moment correlation coefficient and an assessment of the magnitude and …

Effects of the 1982-1983 El Niño mega event on bivalve mollusk biomineralization
… of the ambient seawater environment into their shells (e.g., temperature, dissolved inorganic carbon (DIC)). Bivalves that endure extreme environmental perturbations also exhibit alteration of the shell microstructure in response to the stress. Numerous studies demonstrate correlations between …

Aportes al estudio del metabolismo energético en el niño normal y el malnutrido
El estudio de los fenómenos energéticos que tienen lugar en el metabolismo intermedio del niño, ofrece puntos de apasionante interés. Algunos de ellos han sido dilucidados mientras otros permanecen oscuros. Aún aquellos descriptos como conocidos tiene el incoveniente de su parcialidad dado que …

Impactos do El Niño 1997/1998 sobre a dinâmica da Corrente do Brasil
El Niño-Sul Oscillation (ENSO) is a widely studied phenomenon of oceanatmosphere interaction, due to its global climate impact. The phenomenon has two phases, a hot phase (El Niño) and a cold phase (La Niña). ENSO remotely influences the South Atlantic's Subtropical High (SASH) winds pattern, which …

El Niño Southern Oscillation teleconnections and their effects on the Amundsen Sea region
El Niño Southern Oscillation events have global implications both climatologically and socio-economically. One such climatological teleconnection is manifested in the Amundsen Sea region (ASR). The Amundsen sea low (ASL) is the dominant low pressure system located around the ASR and is important to …

Procesos de comprensión y esquemas de conocimiento: adquisición, desarrollo y organización en el niño
Mediante este trabajo hemos propuesto un modelo en el que se articula una normativa (teoria, metodos, procedimientos, tecnicas, indices, etc.) en un ambito nuevo de aplicacion: la adquisicion del conocimiento en el niño (nelson,1981) y su comparacion con los adultos. Para conseguir estos objetivos, …

Quantifying the immediate carbon emissions from El Niño-mediated wildfires in humid tropical forests
… CO2 emissions in the humid tropics during El Niñomediated extreme droughts, and these emissions are expected to increase in coming decades. Immediate carbon emissions from uncontrolled wildfires in human-modified tropical forests can be considerable owing to high necromass fuel loads. Yet, …

Impactos do El Niño Oscilação Sul na produção de milho no Rio Grande do Sul
O El Niño Oscilação Sul - ENOS, popularmente conhecido como El Niño ocorre no oceano Pacífico, próximo a região do Peru. A região Niño 3.4 é monitorada e caso seja percebido um aquecimento anormal na temperatura da superfíci da água, caracterizando a fase El Niño, mas caso haja resfriamento anormal …

The Evolution of the El Niño-Southern Oscillation and Tropical Pacific Climate Across the Last Deglaciation
<p>The El Niño – Southern Oscillation (ENSO) is the largest interannual component of Earth’s climate system, capable of exerting significant influence over global climate patterns that affect communities around the globe. Nevertheless, a comprehensive understanding of the ENSO system and its …

Machine Learning and Geostatistical Approaches for Discovery of Weather and Climate Events Related to El Niño Phenomena
<p>El Nino and La Nina are worldwide environmental phenomena brought about by repetitive changes in the water temperature of the Pacific Ocean. Even though the El-Nino impact focuses on a smaller area in the Pacific Ocean near the Equator, these developments have global repercussions, where …

Learning-Based Modeling of Weather and Climate Events Related To El Niño Phenomenon via Differentiable Programming and Empirical Decompositions
… methods in the study and characterization of the El Niño Southern Oscillation. In specific, it focuses on ENSO’s effects on rainfall and drought conditions in two major regions shown to be linked through the strength of the dependence of their climate on ENSO: 1) the southern Pacific Coast of the …

An evaluation of historical fire occurrence, drought, and the El Niño southern oscillation in the greater Cross Timbers region, U.S.A
A concern over wildfire occurrence, and its relationship to drought and a changing climate has brought increased focus to the interface between the public and fire. Multiple factors, including an increase in fuel loading from decades of continuous fire suppression, changes in land use and …

An investigation into the causes for the reduction in the variability of the El Niño-Southern Oscillation in the early Holocene in a global climate model
… for this using output from a Global Climate Model forced by present day and early Holocene boundary conditions, and a simplified model that is known to simulate the El Nino-Southern Oscillation (ENSO).We devise a scheme to incorporate mean state data, into the background states of a …
