All Linear-Solid Varieties of Semirings

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2019
A variety of semirings is said to be solid if each of its identities is satisfied as hyperidentity. There are precisely four solid varieties of semirings.

All Regular-Solid Varieties of Idempotent Semirings

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2017
The lattice of all regular-solid varieties of semirings splits in two complete sublattices: the sublattice of all idempotent regular-solid varieties of semirings and the sublattice of all normal regular-solid varieties of semirings.

MULTI-HYPERSUBSTITUTIONS AND COLORED SOLID VARIETIES [PDF]

open access: yesInternational Journal of Algebra and Computation, 2006
Hypersubstitutions are mappings which map operation symbols to terms. Terms can be visualized by trees. Hypersubstitutions can be extended to mappings defined on sets of trees. The nodes of the trees, describing terms, are labelled by operation symbols and by colors, i.e. certain positive integers.

Nonsolidity of uniruled varieties

open access: yesForum of Mathematics, Sigma, 2023
AbstractWe give conditions for a uniruled variety of dimension at least 2 to be nonsolid. This study provides further evidence to a conjecture by Abban and Okada on the solidity of Fano 3-folds. To complement our results we write explicit birational links from Fano 3-folds of high codimension embedded in weighted projective spaces.

Application of X-ray Microtomography to Quantify the Liquid Fraction of M2 Steel for Semi-solid Forming process [PDF]

open access: yes, 2013
Thixoforging, one variant of semi-solid metal processing in which the metallic alloys are processed at low liquid fraction (0.1< Fl < 0.3), is used to produce complex parts with high mechanical properties.

The Clone of K*(n, r)-Full Terms

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2019
Let τn be a type of algebras in which all operation symbols have arity n, for a fixed n ≥ 1. For 0 < r ≤ n, this paper introduces a special kind of n-ary terms of type τn called K*(n, r)-full terms. The set of all K*(n, r)-full terms of type τn is closed

Response of maize (Zea mays L.) ikenne variety to application of household urban solid wastes compost

open access: yesInternational Journal of Agricultural Research, Innovation and Technology, 2020
Soils fertility declining limits agricultural production in Togo where maize (Zea mays L.) is most cereal cropping and base staple food. Currently, mineral fertilizers are beyond the reach of farmers due to high price and limited availability. This study

Pengaruh Pupuk Organik Padat dan Varietas pada Produktivitas Tebu (Saccharum officinarum L.)

open access: yesJurnal Agro Industri Perkebunan, 2017
Sugarcane is one of the main sugar-producing commodities in Indonesia. The one of the efforts to increase the production and yield of sugarcane can be done by fertilization using organic fertilizer and the use of improved varieties.

First Bites—Why, When, and What Solid Foods to Feed Infants

open access: yesFrontiers in Pediatrics, 2021
Humans are the only mammals who feed our young special complementary foods before weaning and we are the only primates that wean our young before they can forage independently.
