Bresar in 1993 proved that each biderivation on a noncommutative prime ring is a multiple of a commutatot. A result of it is a characterization of commuting additive mappings, because each commuting additive map give rise to a biderivation. Then in 1995, he investigated biderivations, generalized biderivations and sigma-biderivations on a prime ring and generalized the results of derivations fo...

field saturated hydraulic conductivity (kfs) is one of the most important soil properties that considerably contribute to soil quality. however, specifically in the structured soils, the measurement of kfs is difficult and time-consuming. therefore, verifying the simple and fast methods for kfs measurement is needed for effective soil monitoring. this study was conducted to investigate the effe...

‎In this paper we give conditions under which a ring is isomorphic to a structural matrix ring over a division ring.

The effect of alkyl substituents on the C-phenyl and/or the N-Phenyl ring of benzophenylhydroxamic acid on their molecular structure and hydrogen bonding has been investigated. The predominant configuration in CHCl3 is determined by steric and electronic effects. Substituents on the C-phenyl ring favor the cis configuration, while substituents in the N-phenyl ring favor a trans c...

an r-module m is called epi-retractable if every submodule of mr is a homomorphic image of m. it is shown that if r is a right perfect ring, then every projective slightly compressible module mr is epi-retractable. if r is a noetherian ring, then every epi-retractable right r-module has direct sum of uniform submodules. if endomorphism ring of a module mr is von-neumann regular, then m is semi-...

Abstract. Saturated and near-saturated soil hydraulic conductivities Kh (mm h−1) determine the partitioning of precipitation into surface runoff infiltration are fundamental to soils' susceptibility preferential flow. Recent studies found indications that climate factors influence Kh, which is highly relevant in face change. In this study, we investigated relationships between pedoclimatic also...
