Strategies for Sustainable Water Management: Hydrochemical Profiling and Protection Zone Design in Rania Basin, Iraq

Groundwater in the Rania basin, Iraqi Kurdistan region, has been under intensive exploitation in the last two decades, where quantity and quality are both affected. Hence, any attempt to protect the aquifers has become an urgent need. Saruchawa, Qulai Rania, and Qulai Kanimaran are the three large springs, among dozens of others in the area, that are heavily relied on as the sole or main source of water supply. Hydrochemical analysis, the first and most practical step to evaluating the water quality, was carried out through 60 water samples collected from 13 springs and 17 wells in both dry and wet seasons (October 2018 and May 2019). Laboratory results show a high calcium bicarbonate concentration with weak acids’ dominance. Protection zones are delineated for these springs using aquifer susceptibility to contamination and analysis of the recession part of the spring curves. The equivalent relationship between the protection factor (Fp) produced by the Epikarst, protective cover, infiltration condition, and Karst network development mapping method and the groundwater protection zone (S) is considered. Qulai Rania and Kanimaran Springs are mapped to be in S2 (a highly vulnerable area), whereas Saruchawa Spring is located in S1 (very highly vulnerable). Based on the second method results (recession curve analyses), all three selected springs fall under the (D-type) vulnerability category. As a result, the immediate protection zone was going to be surrounded by the inner protection zone, and both are enclosed within the outer protection zone, which covers the remainder of the catchment area

Moreover, novel effective computational methods have been developed and suggested in this study by suitable base functions, namely Chebyshev, Bernstein, Legendre, and Hermite polynomials. The utilization of the base functions converts the nonlinear problem to a nonlinear algebraic system of equations, which is then resolved using the Mathematica®12 program. The development of effective computational methods (D-ECM) has been applied to solve the nonlinear Jeffery-Hamel flow problem, then a comparison between the methods has been shown. Furthermore, the maximum error remainder ( ) has been calculated to exhibit the reliability of the suggested methods. The results persuasively prove that ECM and D-ECM are accurate, effective, and reliable in getting approximate solutions to the problem

Synthesis, Characterization, Thermal Analysis and Structural Studies of New Complexes with Tetradentate Ligand

Some new complexes of 4-(5-(1,5-dimethyl-3-oxo-2-phenyl pyrazolidin-4- ylimino)-3,3-dimethyl cyclohexylideneamino) -1,5- dimethyl-2- phenyl -1H- pyrazol -3(2H) –one (L) with Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Pd(II), Re(V) and Pt(IV) were prepared. The ligand and its metal complexes were characterized by phisco- chemical spectroscopic techniques. The spectral data were suggested that the (L) as a neutral tetradentate ligand is coordinated with the metal ions through two nitrogen and two oxygen atoms. These studies revealed Octahedral geometries for all metal complexes, except square planar for Pd(II) complex. Moreover, the thermodynamic activation parameters, such as ?E*, ?H, ?S, ?G and K are calculated from the TGA curves using Coats –Redfern method. Hyper Chem -8 program has been used to predict structural geometries for compounds in gas phase. The heat of formation (?Hf) and bin ding energy (?Eb) at 298 °K for the free ligand and its metal complexes were calculated by PM3 method. The synthesized ligands and their metal complexes were screened for their biological activity against bacterial species, two Gram positive bacteria (Bacillus subtilis and Staphylococcus aureus) and two Gram negative bacteria (Escherichia coli and Pseudomonas aeruginosa)

EVALUATING THE LEVELS OF OXIDATIVE DNA DAMAGE IN HUMAN LYMPHOCYTES IN RESPONSE TO CAFFEINE USING COMET ASSAY (SINGLE CELL GEL ELECTROPHORESIS)

Objectives: Caffeine asin (coffee, cola, and tea) is the most widely consumed beverages worldwide. The current study aims to evaluate the effects of caffeine in different concentrations on human cultured peripheral lymphocytes, in healthy individuals, using comet assay. The extent of DNA damage reflects a balance between oxidative stress (the presence of hydrogen peroxide H2O2 as a reactive oxygen species ROS), and DNA repair ability (the presence of anti-oxidant may be caffeine substances at known concentrations). This is an important method to prevent and avoid many cancerous diseases in an era of various pollutants.Methods: Ten milliliters of venous blood samples were collected from 40 healthy young individuals, and lymphocyte cultures were set up after lymphocyte isolation with ficoll centrifugation. The mixture of lymphocytes culture media was incubated in the sterile incubator for 5 min after adding serial concentrations of caffeine (100, 500, 5000, 10000) µg/ml, as(group1,2,3,4 respectively) to 5% H2O2. The levels of oxidative DNA damage were expressed as comet tail length.Results: At concentration 100 ug/ml, there was a significant elevation in the mean comet tail length level in cultured lymphocytes treated with hydrogen peroxide (106.96 µm) compared with the treated with All (mixture of caffeine, and H2O2), 6.670 µm.Conclusion: We've concluded that a caffeine concentration of 100 µg/ml possesses the strongest anti-oxidant properties and causes much less DNA damage in lymphocytic culture when exposed to hydrogen peroxide.Keywords: Oxidative DNA damage, Comet assay, Lymphocyte, Hydrogen peroxid

MERS coronavirus outbreak: Implications for emerging viral infections

In September 2012, a novel coronavirus was isolated from a patient who died in Saudi Arabia after presenting with acute respiratory distress and acute kidney injury. Analysis revealed the disease to be due to a novel virus which was named Middle East Respiratory Coronavirus (MERS-CoV). There have been several MERS-CoV hospital outbreaks in KSA, continuing to the present day, and the disease has a mortality rate in excess of 35%. Since 2012, the World Health Organization has been informed of 2220 laboratory-confirmed cases resulting in at least 790 deaths. Cases have since arisen in 27 countries, including an outbreak in the Republic of Korea in 2015 in which 36 people died, but more than 80% of cases have occurred in Saudi Arabia.. Human-to-human transmission of MERS-CoV, particularly in healthcare settings, initially caused a ‘media panic’, however human-to-human transmission appears to require close contact and thus far the virus has not achieved epidemic potential. Zoonotic transmission is of significant importance and evidence is growing implicating the dromedary camel as the major animal host in spread of disease to humans. MERS-CoV is now included on the WHO list of priority blueprint diseases for which there which is an urgent need for accelerated research and development as they have the potential to cause a public health emergency while there is an absence of efficacious drugs and/or vaccines. In this review we highlight epidemiological, clinical, and infection control aspects of MERS-CoV as informed by the Saudi experience. Attention is given to recommended treatments and progress towards vaccine development
