In the name of Allah, the Beneficent, the Merciful.
Praise be to Allah, Lord of the Worlds and peace and blessings on the honest and trustworthy (Muhammad) and his family and his divine good companions.
The Islamic clothing is one of the requirements of the common and original innateness to humans; the innateness that is created by God to all people, Allah says, (So set thou thy face steadily and truly to the Faith: [establish] Allah's handiwork according to the pattern on which He has made mankind: no change [let there be] in the work [wrought] by Allah: that is the standard Religion: but most among mankind understand not) (1). Islam as a natural religion has ordered the Muslims to wear decently, Allah says, ( O Children of Adam!

Let G be a graph, each edge e of which is given a weight w(e). The shortest path problem is a path of minimum weight connecting two specified vertices a and b, and from it we have a pre-topology. Furthermore, we study the restriction and separators in pre-topology generated by the shortest path problems. Finally, we study the rate of liaison in pre-topology between two subgraphs. It is formally shown that the new distance measure is a metric

Subject Review: Toxic leadership in the workplace environment

The leadership has received significant attention from researchers for its positive impact on workers and organizational success. Recently

studies have begun to focus on the darker side of leadership and its impact on followers and the work environment. Toxic leadership has been identified as the most dangerous leadership style

resulting in both material and moral costs to organizations in various aspects. Toxic leadership affects the motivation of subordinates

their ability to accomplish tasks

and their desire to continue working. Toxic leaders employ intimidation

exclusion

bullying

threats

and marginalization of subordinates

negatively impacting their well-being and mental health. Therefore

it has become imperative for organizations to implement appropriate mechanisms to prevent the spread of such destructive toxic behaviors on both individual and organizational levels. Thus

the current research aims to identify toxic leadership by reviewing its most important literature and examining the key behaviors and traits of toxic leaders

as well as their impact on followers and the organizational environment.

The Correlation between SMBH and SFR for Quasars

Galaxies – techniques: spectroscopy

Active galaxies: Quarars.

Y. E.

...Show More Authors

A Spectroscopic study has been focused in this article to study one of the main types of active galaxies which are quasars, and to be more precise this research focuses on studying the correlation between the main engine of Quasi-Stellar Objects (QSO), the central black hole mass (SMBH) and other physical properties (e.g. the star formation rate (SFR)). Twelve objects have been randomly selected for “The Half Million Quasars (HMQ) Catalogue” published in 2015 and the data collected from Salon Digital Sky survey (SDSS) Dr. 16. The redshift range of these galaxies were between (0.05 – 0.17). The results show a clear linear proportionality between the SMBH and the SFR, as well as direct proportional between the luminosit
