Effect of Graphite Filling Pore Structure Size on the Tribology Behaviors of Tin Bronze/45 Steel Pairs With Grease Under Low-Speed and Heavy Load Conditions

open access: yesTribology in Industry, 2023
Copper-based solid lubrication inlay technology is widely used in industrial production, especially in low-speed and heavy load conditions, and the structure and distribution of the filling pore have a significant influence on the friction performance ...

Genetic and Environmental Variations and Associations of the Characters Related to the Grain-Filling Process in Rice Cultivars

open access: yesPlant Production Science, 1999
We examined the involvement of genetic and environmental factors in the variations and associations of the rate and duration of grain filling and the final grain weight in rice cultivars, instead of the simple phenotypic correlation and variance.

Grain filling parameters in high-yielding ns wheat cultivars [PDF]

open access: yesZbornik Matice Srpske za Prirodne Nauke, 2008
Grain yield of wheat is dependent on grain weight, which is the result of grain filling duration and rate. The study was undertaken to examine the relation between grain weight and rate and duration of grain filling in five high-yielding NS wheat ...

X-ray edge problem of graphene

open access: yes, 2007
The X-ray edge problem of graphene with the Dirac fermion spectrum is studied. At half-filling the linear density of states suppresses the singular response of the Fermi liquid, while away from half-filling the singular features of the Fermi liquid ...

Close Binary System GO Cyg [PDF]

open access: yes, 2011
In this study, we present long term photometric variations of the close binary system \astrobj{GO Cyg}. Modelling of the system shows that the primary is filling Roche lobe and the secondary of the system is almost filling its Roche lobe.

Assessment of durum wheat (Triticum durum) genotypes on grain filling parameters

open access: yesThe Indian Journal of Agricultural Sciences, 2023
Durum wheat (Triticum durum Desf.), a crucial crop in the Mediterranean basin, faces challenges due to drought, resulting in substantial yield losses. This study was carried out during the winter (rabi) season of 2020–2021 to determine the influence of ...

The Initiation of Inferior Grain Filling is Affected by Sugar Translocation Efficiency in Large Panicle Rice

open access: yesRice, 2019
Background Large panicle rice has a large sink capacity, but inferior spikelet filling is poor in this variety of rice due to asynchronous grain filling.
