Respiratory heat loss of Holstein cows in a tropical environment
(Springer, 2005-05-01)
In order to develop statistical models to predict respiratory heat loss in dairy cattle using simple physiological and environmental measurements, 15 Holstein cows were observed under field conditions in a tropical ...
Sensible and latent heat loss from the body surface of Holstein cows in a tropical environment
(Springer, 2005-09-01)
The general principles of the mechanisms of heat transfer are well known, but knowledge of the transition between evaporative and non-evaporative heat loss by Holstein cows in field conditions must be improved, especially ...
Shape changes of longan fruits during growth in a tropical environment
(Polish Acad Sciences, 2010-01-01)
In this work we propose a new indicator to classify the best period for longan fruit harvest, based on measurements of its longitudinal and transversal axis during growth. Shape analysis based on area per volume ratio (AN) ...
Solid particles in the tropical lowest stratosphere
(2007-02-22)
We report in situ and remote observations proving occasional occurrence of solid particles in the tropical lowest stratosphere, 200km from deep convective events. The particles were found during field campaigns in Southeast ...
Local and regional features of surface radiation fluxes over the tropical Atlantic ocean near Sao Pedro and Sao Paulo archipelago: Evidence of small scale upwelling
(2012-12-01)
To properly describe the interactions between the ocean and atmosphere, it is necessary to assess a variety of time and spatial scales phenomena. Here, high resolution oceanographic and meteorological data collected during ...
Evaluation of thermal stress indexes for dairy cows in tropical regions
(Sociedade Brasileira de Zootecnia, 2007-08-01)
Seis índices de estresse ambiental foram aplicados a 1.359 dados de 359 vacas Holandesas e 54 vacas Jersey em rebanhos comerciais do Ceará e Rio Grande do Norte. O critério de seleção aplicado aos índices foi sua correlação ...
Heterocyte-forming cyanobacteria from Brazilian saline-alkaline lakes
(Molecular Phylogenetics and Evolution, 2018)
Latent heat loss of Holstein cows in a tropical environment: a prediction model
(Sociedade Brasileira de Zootecnia, 2008-10-01)
Nove vacas Holandesas lactantes com 526 ± 5 kg de peso corporal (cinco predominantemente pretas e quatro predominantemente brancas), criadas em região tropical e manejadas em pastagens, foram observadas com os objetivos ...
