Metal Complexes of Heterocyclic Hydrazone Schiff-Bases: Preparation, Spectral Characterisation and Biological Study
...Show More Authors

New isatinic hydrazone Schiff-base ligands, namely furan-2-carboxylic acid (2-oxo-1,2-dihydro-indol- 3-ylidene)-hydrazide (L1), thiophene-2-carboxylic acid (2- oxo-1,2-dihydro-indol-3-ylidene)-hydrazide (L2) and 2-(pyridine-2-yl-hydrazono)-1,2-dihydro-indol-3-one) (L3) are reported. The ligands were prepared by the condensation of furan-2-carboxylic acid hydrazide (L1), thiophene- 2-carboxylic acid hydrazide (L2), and 2-hydrazino pyridine (L3) with isatine. Monomeric complexes were prepared from the reaction of the corresponding metal chloride with the ligands. The ligands and their nine new complexes of the general formulae [M(Ln)2]Cl2 [where M = Co(II), Zn(II) and Cd(II); n = L1, L2 and L3] were characterised by spectroscopic methods (FTIR, UV–Vis, 1H, 13C NMR), elemental analysis, metal content, magnetic measurement and molar conductance. These studies revealed the formation of six coordinate complexes, in which the geometry about metal atom is a distorted octahedral. Biological activity of the ligands and their metal complexes against Gram-positive bacterial strain Bacillus (G?) and Gramnegative bacteria Ecoli (G-) are evaluated. The effects of prepared compounds depend on the type of tested bacteria. It is clear that the ligands and their metal complexes have a potential effect on the Gram-positive (G?) and Gramnegative (G-) strains of the tested bacteria.

A study of Addictive Inpatients at Ibn-Rushd Psychiatric Teaching Hospital in Baghdad
...Show More Authors

Objective :.
1-Find out the prevalence of alcohol and drugs addiction in two different years before and after the last
war i.e. in 2002 and in 200. 2-Study the association between the addiction
and some variables. 3-Identify the prescribed drugs and other substances that
have been abused
Methodology : A retrospective study has been conducted involving the in-patients at addiction unit-IbnRushd
psychiatric hospital in Baghdad by applying the semi-structured form based on ICD-10 criteria
of addiction and dependency with the confirmation of the specialist psychiatrist diagnosis of
dependency. Data concerning each patient admitted in the hospital was gathered to have an idea about
the problem of addiction (drugs an

A Study of Person Deixis in J. M. Singe's Riders to the Sea
...Show More Authors

This study deals with an important area in the field of linguistics, namely person deixis.
The study aims at: (1) Describing the notion of deixis, its importance, and its place in the field
of linguistics, (2) Presenting a detailed illustration of person deixis, and (3) Conducting an
analysis of person deixis in one of Synge‟s plays Riders to The Sea according to Levinson‟s
model. The most important aim of these three is the third one (the analysis). To achieve this
aim, the researcher depends on Levinson‟s (1983) descriptive approach. According to the
descriptive approach of deixis, the category of person deixis can be defined as the encoding of
the participant roles in the speech situation. This encoding is r

Discoloration of Stretched Clear Elastomeric Chains by Dietary Media (An in vitro study)
...Show More Authors

Background: With the increasing demand on esthetic orthodontic appliances, discoloration of clear elastomeric chains and modules remains an issue which concerns both orthodontics and patients. This in vitro study was conducted to evaluate the effect of exposing stretched clear elastomeric chains from six different companies (Ortho Technology, Ormco, Ortho Organizer, American Orthodontics, Opal and G&H companies) to three types of dietary media (tea, coffee and turmeric). Materials and methods: A total of 960 lengths of six modules were cut from short type elastomeric chain; 160 pieces from each brand. The specimens were stretched 50%, placed on plastic boards, and incubated in water at 37°C for 1 day, 7 days, 14 days and 28 days. Once a

Study the efficacy of intralesional pentoxifylline versus triamcinolone acetonide in keloid scars patients
...Show More Authors

Keloids are prevalent fibro-proliferative tumors, and treating them is still a challenge although intralesional injections of triamcinolone acetonide (TAC) are effective, they have frequently linked adverse effects. Pentoxifylline (PTX) is an anti-fibrotic and anti-inflammatory, and vasodilator. It has not yet been tested for intralesional injection in keloids. The aim of the study is to study the efficacy of intralesional pentoxifylline versus triamcinolone acetonide in keloid scars of 40 patients. In this study, 40 patients with keloid scars regardless of the cause of keloid born, 20 patients have injected with intralesional triamcinolone acetonide, and 20 patients with intralesional pentoxifylline every two weeks until the lesi

Experimental Study of Natural Convection in a Closed Cavity (Static Type Domestic Fridge)
...Show More Authors

This work provides an analysis of the thermal flow and behavior of the (load-free) refrigerator compartment. The main goal was to compare the thermal behavior inside the refrigerator cavity to the freezer door (home refrigerator) effect and install a fan on the freezer door while neglecting the heat transmitted by thermal radiation. Moreover, the velocity distribution, temperature, and velocity path lines are theoretically studied. This was observed without affecting the shelves inside the cabinet and the egg and butter places on the refrigerator door as they were removed and the aluminum door replaced with a glass door. This study aims to expand our knowledge about the temperature and flow fields of this refrigerator mo
