Inhibitory Effects of Biosynthesized Copper Nanoparticles on Biofilm Formation of Proteus mirabilis
...Show More Authors

     This study aimed to explore whether green synthesized copper nanoparticles (CuNPs) can function as an anti-biofilm agent produced by P. mirabilis. The nanoparticles were synthesized from cells free extract of P. mirabilis. Characterization of biosynthesized copper nanoparticles was carried out to determine the chemical and physical properties of the product using atomic-force microscopy (AFM), transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD) and UV-visible spectroscopy. The hexagonal structure was confirmed by XRD, size range was marked 13-19nm by TEM. FESEM was used to confirm the surface morphology. AFM analysis was used to reveal the roughness and distribution of nanoparticles. UV–visible spectra of the synthesized nanoparticles recorded a maximum peak at 380 nm. Copper nanoparticles showed remarkable biofilm inhibitory effects on wild type strains of multidrug resistant Proteus mirabilis.

After incubation for 24 and 48 hours at 37oC with 128 μg/ml sub minimum inhibitory concentration (MIC) of CuO nanoparticles, strong biofilm producer strains showed weak biofilm production. Down regulation changes in LuxS expression using real time PCR technology were detected after treatment with copper nanoparticles of these strains.

Investment of Zakat funds
...Show More Authors

Zakat funds may be invested by the owner or his agent, because there is a delay in the investment, and such delay may harm the beneficiaries.
The scholars agreed on the permissibility of investment if it is received from those who are entitled to zakat after it is received, because if zakat reaches their hands, they become wholly owned by them, and therefore they may dispose of it as the disposition of the owners in their property, like all other permissible acts that are permissible according to shariah. What you will see in the folds of the search, God willing).

Dual of Extending Acts
...Show More Authors

Since 1980s, the study of the extending module in the module theory has been a major area of research interest in the ring theory and it has been studied recently by several authors, among them N.V. Dung, D.V. Huyn, P.F. Smith and R. Wisbauer. Because the act theory signifies a generalization of the module theory, the author studied in 2017 the class of extending acts which are referred to as a generalization of quasi-injective acts. The importance of the extending acts motivated us to study a dual of this concept, named the coextending act. An S-act MS is referred to as coextending act if every coclosed subact of Ms is a retract of MS where a subact AS of MS is said to be coclosed in MS if whenever the Rees factor ⁄ is small in th

Formulation of Rifampicin Suspension
...Show More Authors

     

Rifampicin is the drug of choice in treatment of tuberculosis. Also, it is effective in treatment of various bacterial infections.This study was carried out to prepare a stable suspension for rifampicin through preparation of different formulas of rifampicin aqueous suspension either as ready to use or as granular powder to be reconstituted.The selected formula (A) was evaluated and compared with commercial brand of rifampicin (Rifactine®) as a reference through measuring their dissolution rates and other physical properties.The results indicated that the selected formula had better dissolution rate compared with the reference suspension and the rheogram showed that the selected formula was less

HOFFMAN INDEX OF MANIFOLDS
...Show More Authors

For a connected topological space M we define the homeomorphism and period noncoincidence indices of M, each of them is topological invariant reflecting the abundance of fixed point free self homeomorphisms and periodic point free self maps defined on M respectively. We give some results for computing each of these indices and we give some examples and some results relating these indices with Hoffman index.

Issues of contemporary jurisprudence
...Show More Authors

Islamic jurisprudence is a divine approach capable of confronting all developments that occur in human society and giving appropriate solutions to them. The research discussed opinions related to some contemporary issues according to the rule of no excess or negligence and according to the rules of removing hardship and facilitating in order to reach the appropriate legal ruling for the nature of the situation to which it may be exposed. Man is in paradise, and the research emphasizes the necessity of taking into account the aspect of precaution when deciding on issues, such as the rules of change and the removal of embarrassment
