The discharged water from tannery plants is main source for pollution of soil and groundwater, especially in Nahrawan area. Water samples is collected from 10 sites of wells, discharged water and from using water in different levels of tannery and 7 soil samples from different sites inside factories area and outside it. The results shown that pH for samples of wells and discharged water were within allowable limits between 6.5- 8.5, except the value of pH recorded in the discharged water sample (after the addition of calcium hydroxide) was 12.8, as well as reached the highest value of total dissolved salts (TDS) 7800 ppm in same samples. It also reached its highest value of electrical conductivity (EC) 8200 μS/cm. The results showed that most samples of discharged water recorded high values of turbidity reached to 557 NTU, while the lowest values recorded in water wells and water sample of Nahrawan village. The samples of discharged water was contained high concentration of relatively heavy elements (Pb and Ni), while not sensing concentration of (Cd and Cr), especially for non-use of chromium in the tanning process because of the lack of economic viability by the owners of the factories. The results of analysis of heavy elements in the soil samples to the concentration of Pb in the samples were all within the limits of Iraqi standard was 50-300 ppm. The results indicated that the highest concentration of Ni recorded in samples of soil in the east and south-eastern tanneries exceeding the Iraqi standard concentration of Ni in the soil the amount of 30-75 ppm, while the concentration of Ni in other soil samples was within the limits of the Iraqi standard, while not sensing by concentration of (Cd and Cr) in these samples.
Oral swab samples were collected from 120 children (ages between one month- 10 years) who were infected with oral thrush and 30 healthy children. The percentages of isolated yeasts and Bacteria were 66.6% and 96.6% respectively. The dominate yeast and bacteria were Candida albicans and Staphylococcus aureus with of 78.7% and 34.4% respectively. Results revealed that the highest percent of infection with oral thrush disease was 32.5% in children within the age of 1-2 months.
An experimental study was performed to estimate the forced convection heat transfer performance and the pressure drop of a single layer graphene (GNPs) based DI-water nanofluid in a circular tube under a laminar flow and a uniform heat flux boundary conditions. The viscosity and thermal conductivity of nanofluid at weight concentrations of (0.1 to 1 wt%) were measured. The effects of the velocity of flow, heat flux and nanoparticle weight concentrations on the enhancement of the heat transfer are examined. The Nusselt number of the GNPs nanofluid was enhanced as the heat flux and the velocity of flow rate increased, and the maximum Nusselt number ratio (Nu nanofluid/ Nu base fluid) and thermal performance factor

Show MoreIn this study the Fourier Transform Infrared Spectrophotometry (FTIR) provides a quick, efficient and relatively inexpensive method for identifying and quantifying gypsum concentrations in the samples taken from different sites from different localities from Alexandria district southwest Baghdad. A comprehensive spectroscopic study of gypsum-calcite system was reported to give good results for the first time by using IR for analytical grades of gypsum (CaSO4.2H2O) and calcite (CaCO3) pure crystals. The spectral results were used to create a calibration curve relates the two minerals concentrations to the intensity (peaks) of FTIR absorbance and applies this calibration to specify gypsum and calcite concentrations in Iraqi gypsiferous soi

The current study aimed to assessing the water quality and discussing the hydrochemical characteristics and seasonal variation of surface water on the aspect of metals in Shatt-Al-Hilla, Babil Governorate, Central Iraq. Water samples were collected from eleven sampling sites of Shatt Al-Hila for wet season in March (18/3/2018), and a dry season in July (30/7/2018).
Surface water samples were analyzed for physiochemical parameters such as water temperature pH, EC, TDS, major ions (Ca2+, Mg2+, Na+, K+, SO42-, Cl-, and HCO3-), nutrients (NO3-, and PO43-) for both seasons and DO for one season
