This paper is devoted to investigate experimentally and theoretically the structural behavior of reinforced concrete hollow beams which have internal transverse ribs under effect of shear. The number of the internal ribs is the major variable adopted in this research, while, the other variables are kept constant for all tested specimens. The experimental part includes poured and test of four (200x300x1200mm) beam specimens, three of these specimens were hollow with different locations of internal ribs and one of them was solid. The experimental results indicated that the shear strength are increased (33%) to (60%) for beams containing internal ribs in comparison with reference beam. Also, the change of beam state from ho

This research attempts to evaluate the role of the information system by highlighting its importance in providing date and information to the tax administration the process of tax accounting for those who are subject to income tax whether they are individuals or companies where the effective information system provides accurate and reliable information in a timely manner.

At the theoretical part of the research, the research approaches the problem of the research represented in that whether the information system, applied in the General Commission for Taxes, is capable of achieving its role in reducing the phenomenon of tax evasion. The existence of a set of things which in the Commission may lead to increase tax evasion by taxpa

This work was evaluated the antioxidant, antibacterial and cytotoxic activity of Costus speciosus rhizomes methanol extract. The FLC analysis showed the presence of five compounds in the methanol extract of C. speciosus rhizomes. These compounds were Quercetin (5.2mg/ml), Rutin (6.02mg/ml), Luteolin, (18.3mg/ml),
Kaempherol, (11.34mg/ml) and Coumarin (1.41mg/ml). The maximum antioxidant activity of the extract was at concentration 1000 μg/ml with free radical scavenging activity approximately 67.5%. It was less than standard ascorbic acid 85.5% and Gallic acid 90% with significant difference (p≤0.05), with no significant difference
in comparison with standard TBA 68.5%. The IC50 of extract was 3093

In this study found treatment mice exposed to CCl4 with the alcoholic extract of Pleurotus ostreatus (P2) at (25) mg/ml appeared to exert a beneficial effect since the activities of catalase, was significantly (p<0.05) higher in liver treatment with alcoholic extract of P. ostreatus (P2) (37.290+2.638) μmol/mg than in aqueous extract for the same fungus (36.557+2.231) μmol/mg. Super oxide dismutase (SOD) was significantly (p<0.05) higher in liver treatment with alcoholic extract of P. ostreatus (P2) at (25) mg/ml (17.863+0.454)U/mg than in aqueous extract (17.863+0.454) U/mg for the same fungus and same concentration. Glutathione peroxidase (Gpx) was significantly (p<0.05) higher in liver treatment with alcoholic extract of P.

To synthesize new hydrazone derivatives of naproxen with enhanced anti-inflammatory activity and devoid the ulcerogenic side effects. Hydrazones were synthesized by conjugation of naproxen hydrazide with seven natural and synthetic aldehyde and ketone by using glacial acetic acid as catalyst. The synthesis has been carried out following simple methodology in excellent isolated yields.The structure of the synthesized derivatives has been characterized by elemental microanalysis (CHN), FTIR Spectroscopy, and other physicochemical properties.The anti- inflammatory activity of the synthesized compounds was evaluated in vivo using the egg-white induced edema model in rats, and the results of the biological assay was found to be comparable to Nap

: Clobetasol propionate (CP) is a potent corticosteroid used for skin conditions but often causes side effects due its systemic absorption. To improve its solubility and reduce it side effects (like skin irritation, skin atrophy, hypopigmentation and steroidal acne), Microsponge (Msg) has been employed as a unique three-dimensional particle that can encapsulate hydrophilic and lipophilic drugs. This study aims to develop and evaluate CP Msg-loaded hydrogels. Two Clobetasol-loaded ethylcellulose-based Msg formulas were prepared using the quasi-emulsion solvent diffusion method, then they were incorporated into Carbopol hydrogel. Two ratios of Carbopol 940 (1% and 1.5% w/w) were used. The prepared hydrogel were assessed for appearance, pH, dr

In this work, a series of new maleimides linked to substituted benzothiazole moiety were synthesized. Synthesis of these new cyclic imides were performed via three steps, the first one involved preparation of a series of 2-aminobenzothiazole substituted with different substituents via reaction of different primary aromatic amines with ammonium thiocyanate and bromine in glacial acetic acid. The prepared 2- amino benzothiozoles were introduced in the second step in reaction with maleic anhydride producing a series of N-(substituted benzothiazole-2-yl) maleamic acids.The resulted maleamic acids were dehydrated in the third step via treatment with acetic anhydride and anhydrous sodium acetate to afford a series of the desirable N-(substitu

       The study aimed to reach the best rating for the views and variables in the totals characterized by qualities and characteristics common within each group and distinguish them from aggregates other for the purpose of distinguishing between Iraqi provinces which suffer from deprivation, for the purpose of identifying the status of those provinces in the early allowing interested parties and regulators to intervene to take appropriate corrective action in a timely manner. Style has been used cluster analysis Cluster analysis to reach the best rating to those totals from the provinces that suffer from problems, where the provinces were classified, based on the variables (Edu
