On the Lattice of Existence Varieties of Locally Inverse Semigroups [PDF]

open access: yes, 1994
The mapping which assigns to each existence variety of locally inverse semigroups the class of all pseudosemilattices of idempotents of members of is shown to be a complete, surjective homomorphism from the lattice of existence varieties of locally ...

Towards Defect Phase Diagrams: From Research Data Management to Automated Workflows

open access: yesAdvanced Engineering Materials, EarlyView.
A research data management infrastructure is presented for the systematic integration of heterogeneous experimental and simulation data required for defect phase diagrams. The approach combines openBIS with a companion application for large‐object storage, automated metadata extraction, provenance tracking and federated data access, thereby supporting ...

The Lattice of Varieties of Distributive Pseudo-Complimented Lattices [PDF]

open access: yes, 1970
The lattice of varieties of distributive pseudo-complemented lattices is completely described, viz. a chain of type W + 1. Moreover, each variety is determined by a single equation in addition to those equations which define distributive pseudo ...

Chain varieties of monoids [PDF]

open access: yes, 2018
A variety of universal algebras is called a chain variety if its subvariety lattice is a chain. Non-group chain varieties of semigroups were completely classified by Sukhanov in 1982.

Genetic variability, heritability, and genetic advance of morphological, yield related and quality traits in upland rice (Oryza Sativa L.) genotypes at pawe, northwestern Ethiopia

open access: yesCogent Food & Agriculture, 2023
The rice production in Ethiopia is less than the world’s average due to the lack of varieties with high yield potential. Evaluation of genetic variability is important in the rice breeding program for the production of high yielding varieties.

Rafting of Ni‐Based Superalloys Under Multiaxial Load as Understood by Phase‐Field Simulations and Critical Experiments

open access: yesAdvanced Engineering Materials, EarlyView.
Phase‐field simulations coupled with dislocation‐density‐based crystal plasticity modeling reproduce γ′ rafting behavior in single‐crystal Ni‐based superalloys under varied loading conditions. The model captures both macroscopic creep and microscopic morphology evolution, with results matching high‐temperature creep experiments.

Cancellable elements of the lattice of semigroup varieties [PDF]

open access: yes, 2018
We completely determine all commutative semigroup varieties that are cancellable elements of the lattice SEM of all semigroup varieties. In particular, we verify that a commutative semigroup variety is a cancellable element of the lattice SEM if and only

Nutrient Uptake and Efficiencies of Orange-Fleshed Sweet Potato (Ipomoea batatas L.) Varieties under Different Rates of Nitrogen and Phosphorus Fertilizers

open access: yesInternational Journal of Agronomy, 2023
Sweet potatoes serve as a staple food and animal feed in Africa and serve as a source of raw materials for the food, feed, pharmaceutical, cosmetic, chemical, and energy industries. The yield of orange-fleshed sweet potatoes is increased when nitrogen (N)

Environmentally stable common bean genotypes for production in different agro-ecological zones of Tanzania

open access: yesHeliyon, 2021
Genotype by environment interaction (GxE) complicates the process of selecting genotypes suitable for quantitative traits like seed yield in beans, hence slows down the development and release of varieties by breeding programs. GxE study on seed yield in

Karl Popper and the Mechanisms of Hydrogen Embrittlement

open access: yesAdvanced Engineering Materials, EarlyView.
Representation of the beginning of loss of ductility rather than embrittlement. Small concentrations of hydrogen in a diffusible form within iron are well‐established to harm the mechanical integrity of steels. There are theories that attempt to explain the pernicious role of hydrogen.
