3D Printing of Highly Dense and Translucent Zirconia Parts for Dental Applications: Effect of Filament Overlapping

Advanced Materials Technologies, EarlyView.
This study formulated a 5Y‐PSZ zirconia paste for extrusion‐based additive manufacturing via direct ink writing, producing dense ceramic structures for dental applications. A colloidal approach with 47 vol% nanometric powder and tailored additives optimized rheology and printability.

Ductility Tuning via Cluster Network Characteristics of Porous Components

Advanced Materials Technologies, EarlyView.
Network optimization via cluster characteristics induced by interaction of stress concentration is proposed, demonstrating increased cluster size and dispersion in non‐uniform porous components. The optimized structures exhibit, for the first time, that enhanced ductility and damage progression is controllable through zigzag cluster network designed by

Factors controlling grain weight in wheat

Nature, 1977
THE physiological factors controlling differences in grain weight between cultivars of wheat are not fully resolved. The experiments described here indicate that final grain weight in two cultivars of wheat is mainly dependent on the rate of accumulation of dry matter, which in turn is governed by the number of endosperm cells formed.

Carpel weight, grain length and stabilized grain water content are physiological drivers of grain weight determination of wheat

Field Crops Research, 2011
Abstract Among the yield components, grain weight is considered a conservative trait whose determination is still beyond our complete understanding. Crop physiology uses a whole approach to study this complex trait, which can provide helpful information to plant breeders and molecular biologists.

The weight of the mature wheat grain

Planta, 1970
Grains retained on the plants of some cultivars of common bread wheat lose dry matter after ripeness is attained, but later gain dry matter again. We conclude that the post-ripe plant may remain metabolically active.

Can Whole Grain Help in Weight Management?

Journal of Clinical Gastroenterology, 2014
Evidence from epidemiological studies suggests that higher whole grain intake is associated with improvements in body weight measures. Evidence from randomized controlled intervention studies is controversial.To assess the scientific evidence, using a descriptive systematic approach, related to the relationship/effects of whole grain on weight ...

Rice PCR1 influences grain weight and Zn accumulation in grains

Plant, Cell & Environment, 2015
AbstractProteins containing a placenta‐specific 8 domain (PLAC8) function as major organ size regulators in Solanum lycopersicum and Zea may, and putative metal ion transporters in Arabidopsis thaliana, Oryza sativa and Brassica juncea. However, it is unknown how PLAC8 domain‐containing proteins fulfill such diverse roles.

The association between grain volume and grain weight in wheat

Journal of Cereal Science, 1984
Observations were made throughout the period from grain set until ripening of the changes in weight, volume, water content and anatomical structure of grains for three heavy-grained and three light-grained cultivars of spring wheat. The density of dry mature grains was determined for samples of 12 cultivars of Triticum aestivum and one T.

Weighted selection on coarse-grain hypercubes

Proceedings.Seventh IEEE Symposium on Parallel and Distributed Processing, 2002
Given n weighted records distributed evenly among a p-processor hypercube, p/spl les/n, we present efficient parallel algorithms for solving the weighted selection and related problems in the coarse-grain weak-hypercube model. A special case of the weighted selection problem, in which all the weights are equal, is known as the (unweighted) selection or

gw2.1, a new allele of GW2, improves grain weight and grain yield in rice

Plant Science, 2022
Grain weight is an important characteristic of grain shape and a key contributing factor to the grain yield in rice. Here, we report that gw2.1, a new allele of the Grain Width and Weight 2 (GW2) gene, regulates grain size and grain weight. A single nucleotide substitution in the coding sequence (CDS) of gw2.1 resulted in the change of glutamate to ...
