Grain Destruction in Interstellar Shocks [PDF]
Astrophys.Space Sci.233:111-123,1995, 1995 Interstellar shock waves can erode and destroy grains present in the shocked gas, primarily as the result of sputtering and grain-grain collisions. Uncertainties in current estimates of sputtering yields are reviewed. Results are presented for the simple case of sputtering of fast grains being stopped in cold gas.

Revealing curvature and stochastic effects on grain growth kinetics: A thermodynamic perspective from the extremal principle [PDF]
arXiv, 2021 In the theoretical development of normal grain growth, the roles of "drift" (curvature effect) and "diffusion" (stochastic effect) have been an open question for many years. By coupling contributions of microstructure entropy and grain topological interactions with thermodynamic extremal principle (TEP), this letter extends the existing thermodynamic ...

PLoS ONE, 2018 Two winter wheat (Triticum aestivum L.) populations, i.e. 180 genetic resources and 210 elite varieties, were compared in a field trial to analyse how grain number and grain yield distribution along the spike changed during the breeding process and how ...

The Galactic IMF: origin in the combined mass distribution functions of dust grains and gas clouds [PDF]
, 2011 We present here a theoretical model to account for the stellar IMF as a result of the composite behaviour of the gas and dust distribution functions. Each of these has previously been modelled and the models tested against observations. The model presented here implies a relation between the characteristic size of the dust grains and the characteristic

Investigation of correlation between traits and path analysis of rice (Oryza sativa L.) grain yield under coastal salinity [PDF]
Electronic Journal of Plant Breeding, 2011 Correlation and path analysis was carried out to study the association between quantitative traits on yield of rice. Grain yield perplant exhibited positive and significant association with number of productive tillers, panicle length, number of grains ...

Effects of planting date and density on yield, yield components and protein content of three chickpea (Cicer arietinum L.) cultivars under rainfed conditions in Ilam province [PDF]
پژوهشهای حبوبات ایران, 2012 In order to study the effects of planting date and plant density on yield and its components in three chickpea (Cicer arietinum L.) cultivars in rainfed conditions of Ilam, a field experiment was carried out using split plot design as factorial by ...

Genomic prediction and selection response for grain yield in safflower
Frontiers in Genetics, 2023 In plant breeding programs, multiple traits are recorded in each trial, and the traits are often correlated. Correlated traits can be incorporated into genomic selection models, especially for traits with low heritability, to improve prediction accuracy.
