A Shell Script Compiler in Linux and Unix
Abstract: A command programming language that provides an interface to the UNIX operating system is known as the UNIX shell. It contains some of the mechanisms found in algorithmic languages, such as passing control flow primitives, variables, and parameters. Configurations such as while, if, for, and case are available. Two-way communication is possible between the shell and the command. String value parameters (usually filenames or flags) can also be passed to …

Network Monitoring Tool in Shell Programming
Abstract: Network monitoring is the systematic effort of a computer network to detect slow or failing network components such as overloaded or crashed/frozen servers, failing routers, failed switches, or other problematic devices. The network monitoring system notifies the network administrator in the event of a network failure or other outage. Network management is a subset of network monitoring. Network monitoring is typically accomplished through the use of software applications and tools. …

Projectivity of Universal Algebras
Abstract: The basic relations between universal algebras are homomorphisms and their special cases – monomorphisms, epimorphisms, and isomorphisms (cf., for example, (Kurosh, 1963; Cohn, 1965)). In this paper, we introduce and study a novel relation between universal algebras, which is called projectivity and allows obtaining properties of universal algebras from properties of those universal algebras to which they are weakly or finally projective. The key property of projectivity relations is that …

The Mechanism of Regulation of Chemolithotrophic Sulfur Oxidation in Pseudaminobacter salicylatoxidans KCT001
Abstract: Normal 0 false false false MicrosoftInternetExplorer4 Although the mode of repression of the sulfur oxidation (sox) operon has been elucidated in recent times the mechanism of its derepression is not yet known. Here we propose a comprehensive mechanism of sox gene expression by envisaging redox modulation of soxR as the key to the repression as well as derepression of sox-mediated thiosulfate oxidation Pseudaminobacter salicylatoxidans KCT001. While soxR, rendered to its …
