Simple, sensitive and rapid spectrophotometric method for the determination of mesalazine in pure form and pharmaceutical preparations is described. The method is based on the reaction of mesalazine with p-bromanil in the presence of borate buffer solution of pH9 to form a pink color charge transfer complex of maximum absorption peak (λmax) at 346 nm. Under the optimized reaction conditions, Beer’s law correlating the absorbance with mesalazine concentration was obeyed in the range of 0.48-12 μg ml-1. The molar absorptivity was 6.5×103 L.mol−1cm−1. The limits of detection was 0.053μg ml-1. The accuracy and precision of the method were satisfactory; the average recovery was 98.04% and values of relative standard deviations better than 1.70 %. The stoichiometry of the reaction was studied, and the reaction mechanism was postulated. The proposed method was successfully applied to the determination of mesalazine in its pharmaceutical tablet and capsule with good accuracy and precisions. The results obtained by the proposed method were compared with those obtained by the official method.

The study also demonstrated that the temperature 44c° had a curing effect on the resistance of bacteria under to most studied antibiotics except erythromycin according to this results and because Ascorbic acid is not toxic, it be used with antibiotics against infection with Salmonella typhi

The current study involved isolation and identification of bacteria from (50) urine samples of patients suffering from renal stones and urinary tract infections (UTIs) Sixteen bacterial isolates were obtained from urine samples (32%), Proteus mirabilis and Escherichia coli being the most frequent among isolates, forming 37.5% (6 isolates) and 31.5% (5 isolates) respectively while Klebsiella pneumoniae isolates 12.5% (2 isolates) then Enterobacter aerogenes, Pseudomonas aeruginosa, Staphylococcus aureus were isolated at a rate of (6.25%).
The study showed that 32 (64%) of urine samples were from patients having calcium stone, 10 (20%) with uric acid stone and 8 (16%) with struvite stone but cystine stones were not identified. Furthermore, this study showed that there is a relationship between type of stones and the type of bacterial isolate .
The effects of some factors such as sex and age on the rate of infection with different stone types were investigated ,the results revealed that among (32) calcium stones, 71.9% were males and 28.1% were females. From (8) struvite stones, males represent 37.5% while females were 62.5%, for uric acid stone 60% were males and 40% were female.
The incidence of renal stone seem to be the highest in the age group(30_53) years comprising 48% of the total patients followed by the age group (54_77) years 32% and the least incidence was in the age group (6_29) years 20%

The current study examines the effect of six concentrations of aqueous extracts which are 2.5, 5, 10, 15, 20 and 25% of four medicinal plants on the biological aspects of south beetle beans Callosobruchus maculatus. These plants belong to the family Umbellifera, they are: Coriandor Coriandrum sativum, Cumin Cuminum cyminum, Fennel Foericulum vulgare and Anise Pimpinella anisum. The activity test of these plants was done by soaking chickpeas seeds (the food of the insect) in the previous extracts. The aqueous extracts of Coriandor, Fennel and Anise cause 100% killing of the larval and pupal stages at 25% concentration. The treatment had a significant effect on some of the biological aspects of the first generation pregnancy, since the female productivity decreased to 20.53% at the concentration 25%. Also egg retention occurred in anise treatment. While the productivity of control treatment was 79.26%, also eggs retention was occurred in the female of the southern cowpea beetle which reached 41.70% in Anise treatment at the concentration 2.5%. The study proved that the almost of the above treatments affected the eggs viability of the first generation females.

In order to assess software reliability, many software reliability growth models (SRGMs) have been used for estimation of reliability growth. . In this work, the parameters of (SRGMs) were estimated by using Flower Pollination Algorithm (FPA). Then, the (FPA) was hybrid with Real Coded Genetic Algorithm (RGA) to obtain Hybrid FPA (HFPA).
The results that obtained from (FPA) are compared to the results of five algorithms: Particle Swarm Optimization (PSO), Artificial Bee Colony (ABC), the Dichotomous Artificial Bee Colony (DABC), Classic Genetic Algorithm (CGA) and the Modified Genetic Algorithm (MGA).
The results showed that (FPA) outperformed the rest of the algorithms in parameters estimating accuracy and performance using identical datasets. Sometimes, the (DABC) showed better performance than (FPA).
Other comparisons were made between (FPA) and (HFPA) and the results show that the hybrid algorithm outperformed the original one.

Complexes of Co(II), Ni(II),Cu(II) and Zn(II) with unsymmetrical tetradentate schiff bases ligands H2L1 =2-(1Z)- (8-(2-hydroxy benzylidene amino)naphthalen-1-ylimino) methyl) -6- methoxy phenol, H2L2 =2-((E) -1-(8-(Z)-2- hydroxyl benzylidene amino) naphthalen -1- ylimino) ethyl) phenol and H2L3 = 1-((8-((Z) -2-hydroxy benzylidene amino) naphthalen -1- ylimino) methyl) naphthalene-2-ol, have been prepared in (1:1) (L: M) molar ratio and characterized by elemental analysis, molar conductance, spectral method (I.R, electronic, 1H-NMR), magnetic measurements and metal content analysis. The spectral data suggest that the ligands behave as a dibasic tetradentate ligands with ONNO donor, and coordinate with the metal ion to form mononuclear complexes via the oxygen and nitrogen atoms of the phenolic group and azomethine group respectively. Conductivity data in DMF solution showed that all complexes are non-electrolyte. Magnetic moment and electronic spectra data suggested square planar geometry for all complexes .

Histologically, the result showed that the wall of the glandular stomach in both birds composed of four layers that comprise the rest of the digestive canal, The mucous layer of the glandular stomach in the two birds consist of folds extending into the glandular stomach cavity which known as mucus folds which is lined by simple epithelial columnar tissue, below it lies the lamina properia which contains superficial glands. While Submucosa is fully occupied with deep gastric glands. Muscularis consist of two layers, The internal circular shape and external longitudinal shape, as well as the serosa covered by mesothelim. Histochemically, the epithelial tissue showed moderate positive response for PAS reaction in both birds indicating the presence of moderate quantities of positive mucus materials for PAS reaction
For TB technique epithelial tissue showed a positive response in T. guttat indicating that there is relatively large amounts of acidic mucopolysaccharides in both birds ,while the epithelial tissue in T. guttat. and S. vulgaris showed positive response for AB PH1, AB ph2.5. techniques respectively.

Superficial gastric glands in both birds showed positive response for all techniques used, as well as the deep gastric glands which showed positive response in T. guttat and S. vulgaris for PAS techniques, while the AB PH2.5 and TB technique showed similar responses in both birds. AS for AB-PAS technique, positive responses as were shown in both birds, indicating large quantities of mucin in the secretions of these glands.
