The influence of AME(n) concentration of the diet on productive performance and egg quality traits was studied in Hy-Line brown egg-laying hens differing in initial BW from 24 to 59 wk of age. Eight treatments were arranged factorially with 4 diets varying in energy content (2,650, 2,750, 2,850, and 2,950 kcal of AME(n)/kg) and 2 initial BW of the hens… (More)
The green turtle, Chelonia mydas, is an endangered marine chelonian with a circum-global distribution. Reference blood parameter intervals have been published for some chelonian species, but baseline hematology, biochemical, and blood gas values are lacking from the Galapagos sea turtles. Analyses were done on blood samples drawn from 28 green turtles… (More)
The marine iguana, Amblyrhynchus cristatus, is an iconic lizard endemic to the Galápagos Islands of Ecuador, but surprisingly little information exists on baseline health parameters for this species. We analysed blood samples drawn from 35 marine iguanas captured at three locations on San Cristóbal Island. A portable blood analyser (iSTAT) was used to… (More)
—A high spectral resolution lidar designed for operation in the NSF/NCAR Gulfstream V research aircraft is described. The operational principles of the instrument are described and examples of data are presented. Special design features required for aircraft operation are described.
Endocrine-disrupting chemicals (EDCs) are widespread used and can interfere on hormone regulation with adverse consequences for both biota and human. Vitellogenin (vtg) is a yolk precursor protein synthesized by the liver in response to estrogen. In order to characterize the vtg of tropical fish Rhamdia quelen and establish a molecular biomarker, adult male… (More)
This work presents a mixed-integer nonlinear mathematical programming (MINLP) model aiming at optimizing the sum of transition and inventory carrying costs in a multi-model synchronous assembly line. Different products are assembled in the same line in runs or campaigns, whose sequence and length should be optimally determined. As products show different… (More)
A model predictive controller for optimal braking of a road vehicle is proposed. Taking into account the additional information provided by a torque sensor located in the wheel, there is no need to use any longitudinal model of the vehicle. Instead, we detail a way to identify a tire/road characteristic. This on-line reconstruction is based on an estimation… (More)
