Leishmaniasis is an endemic disease in Iraq, where both forms of the disease, cutaneous and visceral, are found. The effect of Zinc oxide nanoparticles (ZnO NPs) with mean particle size less than 100 nanometer (nm) on viability and growth rate of Leishmania donovani promastigotes was evaluated. The anti-leishmanial activity of different concentrations (0.1, 0.2, 0.4, 0.6, 0.8, and 1 μg/ml) of ZnO NPs was investigated on promastigotes growth rates and viability in comparison to promastigotes exposed to the same concentrations of sodium stibogluconate (Sb) (pentostam).The inhibitory concentrations (IC50s) of ZnO NPs were calculated after 24 , 48 and 72 hr which were (0.871, 0.156 and 0.120 μg/ml) respectively with significant (p< 0.05

                 The research deals with the concept of a New Urbanism as an urban development strategy in the suburbs of cities or in its centers that are affected by pedestrian-oriented design and the possibility of walking, as well as integrating economic classes through the diversity of housing and its costs, and this works to facilitate access to jobs and services while providing more diverse neighborhoods and reducing the use of cars , As designing separate houses in the suburbs and increasing car trips poses a threat to the environment and the quality of urban life, and thus the new urban provides a good strategy for developing

      This research investigates the type and the significant relationship between roaming management and self-efficacy and its impact on excellence in providing hotel service. To achieve this, the applied approach was adopted through  A questionnaire was designed and developed for the collected data. It has consisted of three parts. The firsts section included nine questions to measure the dimensions of management by roaming. The second section includes nine questions to measure the effectiveness of the two employees. The last section includes   12   questions to measure the excellence of the hotel service. The research sample included  43  employees' responding to this

         A group of amine derivatives [4-aminobenzenesulfonamide derivatives, 2-aminopyridine and 2-aminothiazole] incorporated to α-carbon of diclofenac a well known non-steroidal anti-inflammatory drug (NSAID) to increase bulkiness were designed and synthesized for evaluation as  a potential anti-inflammatory agents with expected COX-2 selectivity. In vivo acute anti-inflammatory activity of the selected final compounds (9, 12 and 13) was evaluated in rats using egg-white induced edema model of inflammation in a dose equivalent to (3 mg/Kg) of diclofenac sodium. All tested compounds  produced a significant reduction  in paw edema with respect to the effect of propylene glycol 50
