The present study was conducted to evaluate the effect of fungi Gigaspora margarita and Glomus desriticola in stimulating the resistance of the capsicum annuum L. towards the chromium and lead after 60 days, planting and using the pots in the glass house. The highest concentration of chromium and lead in the root was found in the presence of the mycorrhizal mixture (194.93, 150.40) μg / g, respectively, compared to the lowest concentration (90.69, 79.37) μg / g respectively, while the highest concentration of chromium and lead in the shoot was found in the presence of the mycorrhizal mixture (94.63, 79.33) μg / g respectively, compared with the lowest concentration in the control treatment (72.58, 60.70) μg / g respectively. The results showed the highest uptake efficiency and low translocation and phytoextraction efficiency of chromium and lead (179.73, 0.49 and 19.56) μg / g respectively for chromium and (144.63, 0.53 and 15.29) μg / g respectively for lead. The highest percentage of mycorrhizal mixture was recorded in the Intensity of the Mycorrhizal Colonization in the root System and root Fragments reached to (23.61, 26.50) % respectively, while the lowest percentage in mixing (chromium+lead) was (13.22, 13.47) % respectively. The highest percentage of mycorrhizal dependency was found in the mycorrhizal mixture with mixing (chromium+lead) which was 193.16% compared with the least of mycorrhizal dependency in Gigaspora margarita reached 98.34%. The lowest magnesium content in the control treatment was 28.36 mg / dry weight while the mycorrhizal mixture recorded the highest content of 33.41 mg / dry weight. The highest activity of guaiacol peroxidase and glutathione reductas in the treatment of the mycorrhizal mixture and mixing to heavy metals was (50.93, 10.11) absorption unit / gw fresh roots respectively compared with the lowest activity of the enzyme in the control was (31.48, 3.55) absorption unit / gw fresh roots respectively, all the tables showed significant differences.
Generally, different propositions show that culture changes because of many factors, and acculturation has emerged out of important operations which lead to cultural change as a result of contact between different societies or cultures. Since the cultural environment with its varying effects plays a major role in the formulation of architectural products, the research defined its research problem as follows: There is need for knowledge to specify the results of acculturation at the level of plans of house architecture belong to Iraqi elites in Baghdad city during the late Ottoman rule in Iraq(1830-1917). The research depends on the comparative procedure to define the acculturation results, so the plans character of

Exploring how chemotherapy and anxiety work together to affect the speed at which cancer cells multiply and the immune system’s response model is necessary to come up with ways to stop the spread of cancer. This paper proposes a mathematical model to investigate the impact of psychological scare and chemotherapy on the interaction of cancer and immunity. The proposed model is accurately described. The focus of the model’s dynamic analysis is to identify the potential equilibrium locations. According to the analysis, it is possible to establish three equilibrium positions. The stability analysis reveals that all equilibrium points consi

Materials and Methods: Master brass die was scanned ,then metal coping was designed and milled from Ceramill Sintron blank to get 60 metal copings, then divided randomly into three groups(20 sample), then veneered with porcelain: VITA, Creation or GC. The marginal gaps were measured before and after porcelain veneering then marginal fit changes was calculated. Fracture resist

Along these lines, the impact of "raw petroleum" on soil contamination is one of most critical subjects that review these days. The present examination expects to research "unrefined oil"effectson the mechanical and physical properties of clayey soils. The dirt examples were acquired from Al-Doura area in Baghdad city and arranged by the "Brought together Soil Grouping Framework (USCS)" as silty mud of low pliancy (CL). Research center tests were done on contaminated and unpolluted soil tests with same thickness. The dirtied tests are set up by blending
