Synthesis of microporous/mesoporous core-shell materials with crystalline zeolitic shell and supported metal oxide silica core
(Royal Society of Chemistry, 2016-04)
An engineered material, possessing a hierarchical porosity in a shape selective manner, was synthesized by placing a microporous silicalite-1 shell over silica microspheres embedded with various guest species. Core materials ...
Qualidade interna e externa de ovos de poedeiras
(Universidade Federal de Minas GeraisUFMG, 2016-11-25)
The objective of this research was to evaluate the correlation between internal and external egg quality measures and the age of the laying hens. 300 eggs were used from Lohmann LSL® laying hens with 33, 53 and 73 weeks ...
Quantitative estimates of time-averaging in terebratulid brachiopod shell accumulations from a modern tropical shelf
(Paleontological Soc Inc, 2003-06-01)
Quantitative estimates of time-averaging in marine shell accumulations available to date are limited primarily to aragonitic mollusk shells. We assessed time-averaging in Holocene assemblages of calcitic brachiopod shells ...

What makes a good home for hermits? Assessing gastropod shell density and relative strength.
(Bergen, 2016)
The survival and reproductive success of hermit crabs is intrinsically linked to the quality of their domicile shells. Because damaged or eroded shells can result in greater predation, evaluating shell structure may aid ...
Age influence on quality of shell and penetration in bacterial laying lightweight eggs
(2017-01-01)
This study evaluated the influence of the bird's age on the quality of the shell and percentage of bacterial penetration in commercial eggs. White-shelled commercial eggs were used, laid by light laying hens in their first ...
