The method of operational matrices based on different types of polynomials such as Bernstein, shifted Legendre and Bernoulli polynomials will be presented and implemented to solve the nonlinear Blasius equations approximately. The nonlinear differential equation will be converted into a system of nonlinear algebraic equations that can be solved using Mathematica^®12. The efficiency of these methods has been studied by calculating the maximum error remainder ( ), and it was found that their efficiency increases as the polynomial degree (n) increases, since the errors decrease. Moreover, the approximate solutions obtained by the proposed methods are compared with the solution of the 4^th order Runge-Kutta meth

     The ceramic PSCCO (PbSr₂Ca₂Cu₃O) and (PbSr₂Ca₂Cu_2.4Zn_0.6O) compounds were prepared using high-purity oxides (x=0 and0.6%) via solid reaction. The samples were then pressed into tablets with 1.5 cm diameter, at 5.4MPa for two minutes and sintered at 850°C for 24 hours. AFM was used to study the surface structure. It showed a stable improvement in the crystallization of the model surfaces. As a result of the chemical reaction between the raw materials, the granules united with each other, increasing their size. At a frequency range of 50-10⁶ Hz, regarding the dielectric properties, including the dielectric constant, and dielectric loss factor,

The present study employed the pulsed laser ablation in liquid (PLAL) technique to synthesize cadmium nanoparticles (CdO NPs). PLAL is a top-down physical method that operates by splitting the precursor mass of metal ions into metal atoms. This work utilized a nanosecond Nd-YAG laser with two wavelengths, specifically 1064 nm and 532 nm, at a laser energy of 250 mJ. 250 pulses were applied for each wavelength during the synthesis process. This approach enabled the production of high-purity nanoparticles. The characteristics of the nanoparticles that were created were examined by the use of UV-Vis, and XRD analysis techniques. The antibacterial and antifungal properties of the tested substance were evaluated against two Gram-positive bact

     Novel complexes were synthesized from Schiff base ligand (L) produced by reacting 3-hydrocyclo-1,3-dihydro-indole-2-one (A) with 2-pyridine carboxaldehyde in an ethanol medium. This study aims to synthesize the metal Schiff base ligands complexes of heterocyclic, which tested their biological activity as antimicrobial drugs. Metal complexes comprising manganese, cobalt, nickel, copper, and zinc with Schiff base have been produced at a molar ratio of 1:1 (M: L). These complexes were identified using M.P, FT-IR, UV-Vis, Mass, ¹H-NMR, and C.H.N. Chloride-containing, atomic absorption, molar conductance, and magnetic susceptibility have all been used to identify these compounds. Utilizing mass spectroscopy, the molecular

This research aims to reveal the quality standards available in press images published in the news sites, the Iraqi News Agency and Al-Mada Press for the period from: 1/9/2019, to: 30/9/2019. The research is a descriptive research, in which the researcher relied on the survey methodology to achieve its objectives. The research reached a number of results, most notably the weak role of photojournalists in the websites and the adoption of those the Internet as a source for obtaining press images published with news and reports through its pages, as well as the neglect of the standard Description/Comment below the press images, which plays an important function in explaining and interpreting them for users.

Sorption is a key factor in removal of organic and inorganic contaminants from their aqueous solutions. In this study, we investigated the removal of Xylenol Orange tetrasodium salt (XOTS) from its aqueous solution by Bauxite (BXT) and cationic surfactant hexadecyltrimethyl ammonium bromide modified Bauxite (BXT-HDTMA) in batch experiments. The BXT and BXT-HDTMA were characterized using FTIR, and SEM techniques. Adsorption studies were performed at various parameters i.e. temperature, contact time, adsorbent weight, and pH. The modified BXT showed better maximum removal efficiency (98.6% at pH = 9.03) compared to natural Bauxite (75% at pH 2.27), suggesting that BXT-HDTMA is an excellent adsorbent for the removal of XOTS from water. The equ

Background Tinea versicolor is a common dermatological problem worldwide in distribution, caused by dimorphic fungus called Malassezia furfur, they exist at the very interface between
commensal and pathogen and, as such, their interaction with the human immune system is of great interest. Immuno-inflamatory activity mediated by different cytokines could have a role in the etiology of tinea versicolor.
Patients and Method: The study covered 46 subjects .It comprised 26 patients with TV compared with 20 healthy normal controls. Serum IL-6 analysis was done by ELISA.
Results: The level of IL-6 was elevated in patients with tinea versicolor, when compared with healthy control
Conclusion: IL-6 increases du

Background: Tympanometry findings are considered by many investigators to be associated with passive and active smoking.
Patients and methods: One hundred forty healthy adult men aged (20-50 years). 70 smokers and 70 nonsmokers were recruited for the study. The examination included otoscopy, and screening tympanometry. Smoking history was ascertained by self –report. For each subject, age, smoking status and number of cigarettes per day were noted.
Results: There is a tendency for more negative middle ear pressure in smokers than in non-smokers though this difference may not clinically significant. There were no significant differences in ear canal volume, middle ear compliance and presence of Staped

In the present work, 9-fluorenone-2-carboxylic acid methyl ester (1) was prepared from 9-fluorenone-2-carboxylic acid and then converted into the acid hydrazide (2). Compound (2), is the key intermediate for the synthesis of several series of new compounds such as substituted 1,3,4-oxadiazole derivatives (3-6) were synthesized from the condensation of different substituted benzoic acids with compound (2) using POCl3 as condensing agent. Treatment of compound (2) with formic acid gave the N-formyl hydrazide (7), which upon refluxing with phosphorous pentoxide in benzene yielded the corresponding 5-(9-fluorenone-2-yl)-1,3,4-oxadiazole (8). Reaction of hydrazide (2) with phenyl isocyanate to give N-phenyl semicarbazide derivative (9), then thi

The enemies of religion are still following the approach of undermining the Islamic faith in various ways through the diversity of methods of smear campaigns by raising suspicions to obliterate the Islamic identity and threaten security and stability of social life under the Islamic religion in Islamic societies, as we find that they have employed the doctrine of atheistic thought in order to distance people from the path of truth, distort the features of religion, destabilize psychological security and family stability, and thus destroy societal security by questioning the tolerant faith at times, and by raising suspicions at other times.

Hence, this research came to review the legal duty that requires Islamic scholars to protec

The current research aims to identify the occupational stresses of doctors who are working in governmental hospitals according to the variables of gender and career ranking. The researcher adopted a scale to measure the occupational stress of (1088) doctors (561 males and 527 females) working in governmental hospitals. The results have shown that doctors have a high level of professional stress, but there is no significant difference between doctors in terms of gender. However, there were significant differences in favor of novice residents.
