Formation, spectral and theoretical studies of 1-(4,4-dimethyl-2,6- dithioxo-1,3,5-triazinan-1-yl)-3-(diethylaminocarbonyl)thiourea

The reaction of diethylcarbamic chloride (one mole equivalent), ammonium thiocyanate (two mole equivalents) and thiosemicarbazide (one mole equivalent) in an acetone medium resulted in the formation of the unexpected4,4-dimethyl-2,6-dithioxo-1,3,5-triazinan-1-yl)-3-(diethylaminocarbonyl)- thiourea3in 83% yield. The chemical structure of the title compound was confirmed by IR, NMR and elemental analysis. Further, a suggested mechanism has been proposed to illustrate the route for the formation of the title compound. In addition, theoretical evaluations of the stable geometries of compound3were carried out using semi-empirical molecular quantum calculations with the PM3 method.

Investigation of Sn(IV) and Sn(II) by dianionicligand compounds Supported by Nitrogen-Based Ligands

Synthetic routes to a series of tin compounds incorporating nitrogen-based
chelating ligands are described. The β-diketiminato tin chloride precursor was
utilized to isolate the first tin-phosphorus tin compound using this ligand,
[(HC{C(Me)NAr}2)SnPPh2]. A diamide ligand was employed to investigate tin (II)
and (IV) compounds. Two tin (II) and (IV) compounds, [(Me2Si{ArN}2)SnPh2] and
[Li(OEt)2](Me2Si{ArN}2)SnPh2], were formed via reaction of the lithiated
preligand, [Me2Si{ArNLi}2]+Sn(IV). Finally a novel Sn(II) N-heterocyclic
stannylene compound was formed by reaction of the preligand with SnCl4.
The diamide ligand was found to be suitable for both Sn(IV) and Sn(II)
compounds. Reaction to obtain the tin dich

Electrical properties of pure NiO and NiO:Au thin films prepared by using pulsed laser deposition

The electrical properties of pure NiO and NiO:Au Films which are
deposited on glass substrate with various dopant concentrations
(1wt.%, 2wt%, 3wt.% and 4wt.%) at room temperature 450 Co
annealing temperature will be presented. The results of the hall effect
showed that all the films were p-type. The Hall mobility decreases
while both carrier concentration and conductivity increases with the
increasing of annealing temperatures and doping percentage, Thus,
indicating the behavior of semiconductor, and also the D.C
conductivity from which the activation energy decrease with the
doping concentration increase and transport mechanism of the charge
carriers can be estimated.

The Legal System of the Social Health Insurance in Egypt and its Impact on Iraq

Iraq issued the social Health Insurance Law No. 2 in 2020, thus taking its first step to introduce the universal health coverage. When the previous law was enacted, it was inspired by a number of countries, including the Arab Republic of Egypt, which began implementing the health insurance system since 2018, calling it universal health insurance and issued its law No. 2 of 2018, which was entitled as "The universal Health Insurance Law of the Arab Republic of Egypt". A national project at the all state level, such as the health insurance project, needs a set of equipment, both in terms of preparing the infrastructure or in terms of cooperation with health institutions in the public and private sectors, and both in terms of automating and

A Study Medicinal and Nutritional Effects of Thyme on Hematological Changes in Male Albino Rats

The increase in the use of thyme in Iraq and neighboring countries, which may
be result in serious side effects necessitate the demand for testing different
concentrations of thyme extract (500,750,1000) mg/kg of body weight on rats to be
given either by injection or feeding grinded dried thyme leaves added to pellets
(50,100,150) g /kg of pellet in of different periods , (10,20,30) days for injection
and feeding 2 times weekly. Thyme extracts leaves effects on RBCs, WBCs and
Differential WBCs counts were measured. statistical analysis showed significance
increase difference (P≤0.05) in RBCs, WBCs and Lymphocyte, Nutrophile and
Monocyte counts and decrease in Eosinphil counts in rats treated with 1000 mg of

Viscosity and Density of Chrom Alum in Aqueous Poly (Ethylene Glycol) Solution at Different Temperature

   Density data of  alum chrom in water and in aqueous solution of poly (ethylene glycol) (1500) at different temperatures (288.15, 293.15, 298.15) k have been used to estimate the apparent molar volume (Vθ), limiting apparent molar volume (Vθ˚) experimental slope (Sv) and the second derivative of limiting partial molar volume [δ2 θ v° /δ T2] p .The viscosity data have been analyzed by means of Jones –Dole equation to obtain coefficient A, and  Jones – Dole coefficient B, Free activation  energy of activation per mole of solvent, Δμ10* solute, Δμ20* the activation enthalpy ΔH*,and entropy, ΔS*of activation of viscous flow. These results have been discussed

Oral manifestation biochemical and IgA analysis of saliva in hyperthyroid (Grave’s disease) patients(Comparative study)

Background: Hyperthyroidism occurs due to over production of thyroid hormones, one types of hyperthyroidism was Graves, disease. Hyperthyroidism is characterized by high level of serum thyroxin, triiodothyronine and low level of thyroid stimulated hormones. Material and Methods: fifty two hyperthyroid patients, thirty patients under treatment with carbimazole and other twenty two patients under treatment with radioactive iodine, and sixty healthy control group. The average salivary flow rate was calculated as ml/5mint.The concentration of calcium, potassium, and total protein were determined in the salivary supernatant sample. This is done through different biochemical tests. Determination of salivary IgA is done by ELIZA. Results: The most

Morbidity and Mortality Pattern of Neonates Admitted to Neonatal Care Unit.Central Teaching Pediatric Hospital Baghdad

Background; Neonatal period is a very vulnerable period of life due to many problems, In spite of advances in perinatal and neonatal care still, the mortality rate of neonate high especially in developing country The World Health Organization estimates that globally four million neonatal deaths per year, Developing countries account for around 99% of the neonatal mortality in the world, In Iraq. Neonatal mortality rate about 19 per 1000 live births which represent 56% of child death below 5 years age in 2012. .

Correlation between the histopathological grade and size of breast cancer with axillary lymph node involvement

Background: Breast cancer account for 29% of all newly diagnosed cancer in female and is responsible for 14% of cancer related deaths in women. Breast cancer is basically detected either during a screening tests, before symptoms have appeared, or after a woman notices a mass. Overall risk doubles each decade until the menopause, when the increase slows down or remains stable.
Objective: to find the correlation between the tumor size and grade and involvement of axillary lymph node.
Patients and methods: a continuous prospective study of 50 patients from 1st January 2016 to 1st January 2017 in Baghdad teaching hospital at 1st surgical floor, where almost all patients with breast cancer operated on by modified radical mastectomy and

New Record of the Bottle Liverworts Sphaerocarpos Donnellii Aust. for Iraq and Middle East Countries

    The Order Sphaerocarpales of the bottle liverwort consists of five genera, among which Sphaerocarpos in turn consists of  8-9 species. The genus is nearly worldwide distributed, but disjunct, sporadic, and localized throughout the range in North America, South America, Europe, Africa, and Australia. According to the published checklist, only two species of Sphaerocarpos were recorded in the middle east countries. These are S. texanus and S. michelii, both were found in Turkey, while only the latter was found in Iraq. By the current study, an additional species, S. donnellii, will be added to the byroflora of the Middle East (south west Asia) region. A specimen of this s
