Evaluación ultrasonográfica de la tiroides en crías de vacas lecheras tratadas con yodo en el preparto
(CIENCIAS, 2013)
El objetivo del estudio fue determinar ultrasonográficamente el tamaño de la glándula tiroides y la ganancia de peso de terneros crías de vacas suplementadas con yodo (I) en el preparto. Se utilizaron 14 terneros ...
Características biométricas del cuerpo calloso en individuos chilenos
(CIENCIAS, 2012)
El cuerpo calloso conecta ambos hemisferios cerebrales y se ubica en el fondo de la fisura longitudinal del cerebro. Con el propósito de complementar el conocimiento sobre esta importante estructura del sistema nervioso ...
Explosive style, magma degassing and evolution in the Chaimilla eruption, Villarrica volcano, Southern Andes
(CIENCIAS, 2015)
Villarrica (Chile) is a basaltic stratovolcano, currently in an open-conduit condition. It now has relatively frequent Strombolian and effusive eruptions, but it had large explosive eruptions in prehistoric times. Among ...
The effect of spectral and spatial degradation of hyperspectral imagery for the Sclerophyll tree species classification
(CIENCIAS, 2013)
Hyperspectral imaging can be a useful remote-sensing technology for classifying tree species. Prior to the image classification stage, effective mapping endeavours must first identify the optimal spectral and spatial ...
Constructing satellite-derived hyperspectral indices sensitive to canopy structure variables of a Cordilleran Cypress (Austrocedrus chilensis) forest
(CIENCIAS, 2012)
Satellite hyperspectral data were used to construct empirical spectral indices related to the canopy structure of a Cordilleran Cypress (Austrocedrus chilensis) forest located in the Andes of central Chile. Measurements ...
Aberrant localization of ezrin correlates with salivary acini disorganization in Sjogren's Syndrome
(CIENCIAS, 2010)
OBJECTIVES: To analyse whether the alterations in the structure and organization of microvilli in salivary acinar cells from SS patients are linked to changes in the expression and/or cellular localization of ezrin. METHODS: ...
Changes in surface EMG assessed by discrete wavelet transform during maximal isometric voluntary contractions following supramaximal cycling
(CIENCIAS, 2013)
To better understand characteristics of neuromuscular fatigue in supramaximal cycling exercise, this study examined changes in surface electromyography (sEMG) frequency during maximal voluntary isometric contractions (MVC) ...
Relationship between learning styles and academic performance of fifth graders enrolled in the medical course
(CIENCIAS, 2013)
OBJECTIVE: The aim of this study was to determine the learning styles of fifth-year medical students who attended the ophthalmology course and to also determine the correlation with their academic performance. METHODS: ...
Men and Women Exhibit Similar Acute Hypotensive Responses After Low, Moderate, or High-Intensity Plyometric Training
(CIENCIAS, 2016)
The aim of this study was to compare the acute effects of low-, moderate-, high-, and combined-intensity plyometric training on heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and rate-pressure ...
The conserved PFT1 tandem repeat is crucial for proper flowering in Arabidopsis thaliana
(CIENCIAS, 2014)
It is widely appreciated that short tandem repeat (STR) variation underlies substantial phenotypic variation in organisms. Some propose that the high mutation rates of STRs in functional genomic regions facilitate evolutionary ...
