Humic acid coated sand as a novel sorbent in permeable reactive barrier for environmental remediation of groundwater polluted with copper and cadmium ions
Sewage sludge
Sustainable
Groundwater contamination
Permeable reactive barrier
Humic acid
Plantation of humic acid nanoparticles on the inert sand through simple impregnation to obtain the permeable reactive barrier (PRB) for treating of groundwater contaminated with copper and cadmium ions. The humic acid was extracted from sewage sludge which is byproduct of the wastewater treatment plant; so, this considers an application of sustainable development. Batch tests signified that the coated sand by humic acid (CSHA) had removal efficiencies exceeded 98 % at contact time, sorbent dosage, and initial pH of 1 h, 0.25 g/50 mL and 7, respectively for 10 mg/L initial concentration and 200 rpm agitation speed. Results proved that physicosorption was the predominant mechanism for metals-CSHA interaction because the sorption data followed

Synthesis, spectral characterization and thermal study of complexes of ions of some metallic elements with new cyclic ligands
The purpose of my thesis is to prepare four new ligands (L1-L4) that have been used to prepare a series of metal complexes by reacting them with metal ions: M=(Mn(II), Co(II), Ni(II), Cu(II), Zn(II), Cd(II), Hg(II) Where succinyl chloride was used as a raw material for the preparation of bi-dented ligands (L1-L4) by reacting it with potassium thiocyanate as a first step and then reacting with (2-aminobenzothiazole, Benzylamine, 4-aminoantipyrine, Sulfamethoxazole) respectively as a second step with the use of dry acetone as a solvent, the chemical formula of the four ligands prepared in succession: N1,N4-bis(benzo[d]thiazol-2-ylcarbamothioyl)succinamide (L1) N1,N4-bis(benzylcarbamothioyl)succinami

Using the Water Quality Index as a Powerful Tool to Assess the Water Quality for Drinking Purposes in Al-Salam, Western Region of Baghdad City, Iraq
Water quality index
Drinking water
Pollution.
Background: Tap waters play an important role in fulfilling the people needs for drinking and domestic purposes. Contaminate the tap water with different pollutants has become an issue of great concern for 90% of people who are depended on the tap water as the main source of drinking. Pollutants can make their way easily into the delivering pipes which suffer from the leaking resulting in decreasing the quality of water. Objective: Therefore, assess the water quality for drinking purpose by calculating the water quality index is an important tool to ascertain whether the water is suitable for human consumption or not. Methods: In the present work, the water quality of the Al-Salam, western region of Baghdad city, Iraq was investigated for 7

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.
