Eye Diseases and Impaired Vision as Possible Risk Factors for Recurrent Falls in the Aged: A Systematic Review

open access: yesCurrent Gerontology and Geriatrics Research, Volume 2012, Issue 1, 2012., 2012
Background. Recurrent falls are common among the aged. Vision is needed in maintaining balance, and impaired vision may be an intrinsic risk factor of recurrent falls. The aim was to perform a systematic review about the relationships between eye diseases or impaired vision and the risk of recurrent falls in the aged. Material and Methods.

Optimizing Distributed Real‐Time Embedded System Handling Dependence and Several Strict Periodicity Constraints

open access: yesAdvances in Operations Research, Volume 2011, Issue 1, 2011., 2011
This paper focuses on real‐time nonpreemptive multiprocessor scheduling with precedence and strict periodicity constraints. Since this problem is NP‐hard, there exist several approaches to resolve it. In addition, because of periodicity constraints our problem stands for a decision problem which consists in determining if, a solution exists or not ...

Antibiotic Sensitivity of Vibrio spp. and Shewanella algae Isolated From Brood and Egg of Mud Crab Hatchery

open access: yesAnimal Research and One Health, Volume 4, Issue 1, Page 55-66, February 2026.
Vibrio alginolyticus NBRC 15630, Vibrio parahaemolyticus ATCC 17802, Shewanella algae DW01, and Shewanella algae ATCC 51192 bacterial strains were found in the Mud crab brood and egg samples. All isolates were found to be sensitive to cefotaxime, chloramphenicol, gentamicin, and nitrofurantoin antibiotics.

Mode‐Locking, Quasi‐Period and Chaos of Rotors Mounted on Nonlinear Bearings

open access: yesInternational Journal of Rotating Machinery, Volume 6, Issue 3, Page 191-200, 2000., 2000
This study is to investigate the dynamics of a rotor, with a single degree of freedom (SDOF), mounted on nonlinear bearings. This system has piecewise‐linear stiffness and is subjected to a forcing excitation due to residual mass imbalance as well as a parametric one due to an axial periodic thrust.

S‐J‐Ideals: A Study in Commutative and Noncommutative Rings

open access: yesJournal of Mathematics, Volume 2024, Issue 1, 2024.
In this paper, we introduce the concept of S‐J‐ideals in both commutative and noncommutative rings. For a commutative ring R and a multiplicatively closed subset S, we show that many properties of J‐ideals apply to S‐J‐ideals and examine their characteristics in various ring constructions, such as homomorphic image rings, quotient rings, cartesian ...
