Piranti Lunak Pengujian Struktur Matematika Grup, Ring, Field Berbasis Osp (Open Source Program)

open access: yesComTech, 2014
This design of a computer software is a development and continuation of the software made on the previous research (2009/2010). However, this further research developed and expanded the scopes of testing more on the Siclic Group, Isomorphism Group, Semi

A case of penile strangulation after placement of metallic rings

open access: yesUrology Annals, 2018
Penile strangulation following placement of metallic rings is a rare clinical entity that needs urgent attention to avoid potentially severe clinical consequences.

ON THE REFINEMENT OF THE UNIT AND UNITARY CAYLEY GRAPHS OF RINGS [PDF]

open access: yesJournal of Algebraic Systems, 2019
Let $R$ be a ring (not necessarily commutative) with nonzero identity. We define $Gamma(R)$ to be the graph with vertex set $R$ in which two distinct vertices $x$ and $y$ are adjacent if and only if there exist unit elements $u,v$ of $R$ such that $x+uyv$

On rings on rings [PDF]

open access: yesProceedings of the American Mathematical Society, 1964
This paper presents a solution to a popular problem in the subject of rings of analytic functions. In the late 1940's it was shown that two domains Di and D2 in the complex plane were conformally equivalent (to within a certain equivalence relation) iff the rings B(Di) and B(D2) of all bounded analytic functions defined on them were algebraically ...

Dynamic Concentric Rings Infrastructure for Efficient Communications in Wireless Sensor Networks

open access: yesIEEE Access, 2016
The design of wireless sensor networks (WSNs) has a new paradigm that implies a separation of the underlying communication functionalities from the upper-layer protocols with the goal of leveraging the reusability of protocols.

GROSSLY AND MICROSCOPIC STUDY OF THE TRACHEA AND BRONCHIAL TREE IN THE LOCAL SHEEP ( OVIS ARIS). [PDF]

open access: yesBasrah Journal of Veterinary Research, 2015
The trachea of the local sheep is a tubular structure that begins at the cricoid cartilage of the larynx and ends when it bifurcates to form the principle bronchi, composed of series of incomplete rings that were incomplete dorsally ...

Scythian Bracelets and Rings with Protrusions from the Cemetery Near Glinoe Village

open access: yesНижневолжский археологический вестник, 2021
The article examines bracelets and rings of the La-Tene style from Scythian burials of the cemetery near the Glinoe village, Slobozeya district, on the left bank of the Dniester. Bracelets were found in three burials belonging to different kurgan groups (

Branch rings, thinned rings, tree enveloping rings [PDF]

open access: yesIsrael Journal of Mathematics, 2006
We develop the theory of ``branch algebras'', which are infinite-dimensional associative algebras that are isomorphic, up to taking subrings of finite codimension, to a matrix ring over themselves. The main examples come from groups acting on trees. In particular, for every field k we construct a k-algebra K which (1) is finitely generated and infinite-
