A method for the digital image analysis of ceramic grains based on shape factor segmentation
(2003-03-13)
A very simple and robust method for ceramics grains quantitative image analysis is presented. Based on the use of optimal imaging conditions for reflective light microscopy of bulk samples, a digital image processing routine ...

Feeding variations and shape changes of a temperate reef clingfish during its early ontogeny
(2017)
The majority of rocky reef fishes have complex life cycles, involving transition from a pelagic to a benthic environment. This means that as they grow, their morphology, behaviour and feeding habits must change. Therefore, ...
Silvicultural considerations for the production of poles in Pinus radiata D. Don plantations in Chile
(Univ. Pinar Rio Hermanos Saiz Montes Oca, 2020)
The production of poles in Chile is done by choosing trees specially selected for that purpose, however, the forestry that is massively applied is oriented to the simultaneous production of pruned, sawn and pulpable logs. ...
Effect of steaming treatment in the structure and reactivity of FCC catalysts
(John Wiley & Sons Inc, 2006-02)
The shape selectivity properties of USY zeolite crystallites is discussed, and is based on catalyst characterization, molecular simulation, catalytic experiments of model compounds and kinetic modeling. Typical FCC catalysts ...
Pervasive genetic integration directs the evolution of human skull shape
(Wiley Blackwell Publishing, Inc, 2012-04)
It has long been unclear whether the different derived cranial traits of modern humans evolved independently in response to separate selection pressures or whether they resulted from the inherent morphological integration ...
Ecological and evolutionary factors in the morphological diversification of South American spiny rats

Shape memory epoxy vitrimers based on DGEBA crosslinked with dicarboxylic acids and their blends with citric acid
(Royal Society of Chemistry, 2016-09-02)
Thermosetting polymers were synthesized from a commercial epoxy resin (diglycidyl ether of bisphenol A, DGEBA) and tricarboxylic (citric, CA) and different dicarboxylic (sebacic, SA and glutaric, GA) acids. Crosslinking ...
Morphology of migration: associations between wing shape, bill morphology and migration in kingbirds (Tyrannus)
(Oxford Univ Press, 2021-10-21)
Morphology is closely linked to locomotion and diet in animals. In animals that undertake long-distance migrations, limb morphology is under selection to maximize mobility and minimize energy expenditure. Migratory behaviours ...
