Thirteen A.niger isolates were obtained from soil and food samples and screened on tannic acid agar for their ability to produce tannase. There isolates revealed large tannic acid hydrolysis zones, these isolates were cultured in liquid and solid substrate fermentation media to examine their production of tannase quantitatively .Solid substrate medium was more efficient than liquid medium ,and A.niger Ass19 gave the highest tannase productivity. Different kinds of SSF media and cultured conditions were performed to determine their effect on tannase production. The maximum yield of tannase was obtained in wheat bran with tea leaves hydrated with citrate buffer pH 5.5 at 1:3 (w/v) hydration ratio inoculated with 2108 fungal spores and incubated at 28C for 72hr .the tannase productivity was 8200 U/mg at these conditions.
This study aims to explore the potential mediation role of person-centeredness between the effects of the work environment and nurse reported quality and patient safety. A quantitative cross-sectional survey collected data from 1055 nurses, working in medical and surgical units, in twelve Malaysian private hospitals. The data collection used structured questionnaires. The Hayes macro explored the mediation effect of person-centeredness between the associations of work environment dimensions and care outcomes, controlling nurses’ demographics and practice characteristics. A total of 652 nurses responded completely to the survey (61.8% response rate). About 47.7% of nurses worked 7-h shifts, and 37.0% were assigned more than 15 pati

Summary:
Background: Nitre I la sativa Linn is a well known herb that is used by different societies, as food additive and as a medicinal herb: it used as a galactagouge for lactating women, and has long been described as an abortifacient-emmenagouge.
Aim of the work: is to investigate the effect of crude black seeds on the endometrium and the pattern of it’s mucins, during the different phases of the Estrus cycle, making use of some special stains for the histochemical demonstration of mucins.
Materials <6 Methods.'Crude Nieella sativa Linn, seeds were administrated for ten days, by an orogastric tube, on single regular daily dosage to properly selected mature Norway albino female rats. Animats were subdivided into subgrou
The role and procedures for accountability in the spending units significant impact in enhancing the results of the budget it is found by studying and comparing the results of the implementation of the budget for the research sample for a period of two years to repeat the same deviations and irregularities of Guanyin, regulations and instructions that have occurred in implementation results and two consecutive Kaltjaoz customizations and low rates of implementation and the lack of exchange of allocations Finance despite the presence budget note that such remarks are always indicate in regulatory reports, but these observations repeated Bostmr in the results of the implementation of the budget.

New complexes of the [M(Ura)(Phen)(OH2)Cl2]Cl.2H2O type, where (Ura) uracil ; (Phen) 1,10-phenanthroline hydrate; M (Cr+3 , Fe+3 and La+3) were synthesized from mix ligand and characterized . These complexes have been characterized by the elemental micro analysis, spectral (FT-IR., UV-Vis, 1HNMR, 13CNMR and Mass) and magnetic susceptibility as well the molar conductive mensuration. Cr+3, Fe+3 and La+3- complexes of six–coordinated were proposed for the insulated for three metal(III) complexes for molecular formulas following into uracil property and 1,10-phenanthroline hydrate present . The proposed molecular structure for all metal (III) complexes is octahedral geometries .The biological activity was tested of metal(III) salts, liga

I mpact strength for Epoxy/Polyurethane, Blends and their composites with two
layers of Glass fibers (0-90) are calculated.
The impact strength of the blends and composites decrease with increasing weight
by weisht percentage of polyurethane . This result is attributed to the high elasticity
of PU , and to the immiscibility between the polymer blends as well as the fiber

In this research the effect of laser energy by using argon gas on the some physical properties of semiconductor film of TiO2, was studied used Q-Switch Nd:YAG laser in different energies (600-1000) mJ with temperature 100 0C for glass substrate under vacuum nearly 10-3 - - , and by AFM test the roughness of films increased when the energy of laser increased too. The values of roughness between (6.77-13) nm, therefore the thicknesses increased to change from (34.88 - 165.48) nm, so the absorption of film increased because of the thickness of the film increased and we can get the optical energy gap between (3.6-3.9) eV.
The purpose of this research is to enhance the methods of surface seismic data processing and interpretation operations by using the produced information of vertical seismic profile (measured velocity and corridor stack). Sindbad oil field (South of Iraq) is chosen to study goals and it's containing only one well with VSP survey (Snd2) that covering depth from Zubair to Sulaiy Formations and 2D seismic lines of Basrah Survey. The horizons were picked and used with low frequency contents from well data for the construction of low frequency model and it was used with high frequency of VSP to make the high frequency model that compensated to seismic main frequency through inversion process. Seismic inversion technique is performed on post s

The study dealt with the effect o r the anticoagu l ant rodentici de Brcidi facom on the reproduction of male mus musculus trapped from d i ftcrent loculitieo of Uagltdad prov ince and ted with different doses (50
,75 ,100 mg) of pellets of this rodenticide. The results showed n significant decrease (p< 0.0 I ) in testicular weight and volume, epididymal ( head and tail) weight and numbers of different spermatogenic cells. The rodenticide caused a significant decrease in sperms concentration and a significant increase in dead and abnormal sperms in testes and epididymis.
This study were implemented on (60) broiler chick with one day age divided into three equal groups , first one was given basal diet while group two and three given adiet contain 0.01% ,0.02% tryptophan respectively for 7 weeks . The results show that the chicks recevd the tryptophan have asigneficant increasment in hemoglobin concentration, red blood cells count, packed cell volume and increased the level of globuline concentration and lymphocyte % which mean that the addition of tryptophan improve blood picture charactores and the immunity of the broiler chickens and this evident from the good health state and decrease the mortality among birds .
