This study is aimed to use the aerobic packed bed in biotreatment of the wastewater which is discharge from AL-KARAMA teaching hospital in Baghdad. The performance of packed-bed treatment method was examined for elimination of the organic compounds from wastewater under aerobic conditions. In this research different parameters were studied. They were: inoculums concentration, circulation rate of wastewater through the bed, packing type and the temperature. Results showed that the system efficiently removed about 82% of the chemical oxygen demand (COD) and 80% of the Biological oxygen demand (BOD). Percent reduction in turbidity was about 92% and reduction in nitrate concentration was about 87%. It was found that best performance of the packed bed method was obtained at temperature of 37 oC, circulation rate of 10 L/min and inoculums concentration of 3%.
Background: Transient tachypnea (TTN) is a common disorder of the newborn. It is characterized by the
early onset of tachypnea sometimes with retractions or expiratory grunting and occasionally cyanosis that is
relieved by minimal oxygen supplementation (<40%).
Objectives: To identify the risk factors and describe the clinical characteristics, treatment and outcome of
infants with TTN.
Patients and methods: This study was carried out on 100 newborn babies with birth weight of 2500 to 4000 &nbs
Tau-P linear noise attenuation filter (TPLNA) was applied on the 3D seismic data of Al-Samawah area south west of Iraq with the aim of attenuating linear noise. TPLNA transforms the data from time domain to tau-p domain in order to increase signal to noise ratio. Applying TPLNA produced very good results considering the 3D data that usually have a large amount of linear noise from different sources and in different azimuths and directions. This processing is very important in later interpretation due to the fact that the signal was covered by different kinds of noise in which the linear noise take a large part.
In the present work , radon concentration was measured indoor buildings in the College of Education for Pure Science/ Ibn Al- Haitham University of Baghdad using detector (CR-39) by counting track of alpha resulting from decay series of uranium on the detectors which have exposure to air inside the rooms for (30) days , have been applied the equation (1) and (2) to calculate concentrations of Radon and the results showed that all samples were within the allowable range globally except two samples F1 and F2 where concentrations were (445.868Bq/m3) and (436.791Bq/m3) respectively , they were higher than allowable range globally which was (200-300) Bq/m3 recorded by (ICRP) [1] .
Background: Dysentery is an important cause of morbidity and mortality associated with diarrhea. About 10% of all diarrheal episodes in children less than 5 years are dysenteric, but these cause about 15% of all deaths attributed to diarrhea.
Objective : To demonstrate the most common pathogens causing bloody diarrhea in children between 2 months and 5 years old, to describe some of the associated factors accompanying bloody diarrhea and to highlight the most important clinical features.
Patients and methods: A descriptive study of 82 children, between the age of 2 months to 5 years with bloody diarrhea, who were admitted to the Children Welfare Teaching Hospital/ Medical City/Baghdad during the period betw

water quality assessment is still being done at specific locations of major concern. The use of Geographical Information System (GIS) based water quality information system and spatial analysis with Inverse Distance Weighted interpolation enabled the mapping of water quality indicators along Tigris river in Salah Al-Din government, Iraq. Water quality indicators were monitored by taking 13 river samples from different locations along the river during Winter season year 2020. Maps of 10 water quality indicators. This meant that the specific water quality indicator and diffuse pollution characteristics in the basin were better illustrated with the variations displayed along the course of the river than conventional line graphs.

... Show MoreThe Electric Discharge (EDM) method is a novel thermoelectric manufacturing technique in which materials are removed by a controlled spark erosion process between two electrodes immersed in a dielectric medium. Because of the difficulties of EDM, determining the optimum cutting parameters to improve cutting performance is extremely tough. As a result, optimizing operating parameters is a critical processing step, particularly for non-traditional machining process like EDM. Adequate selection of processing parameters for the EDM process does not provide ideal conditions, due to the unpredictable processing time required for a given function. Models of Multiple Regression and Genetic Algorithm are considered as effective methods for determ

Such a step involves using educational techniques, laying the selection foundations, knowing the methods of their employment and tracking the obstacles that limit this employment in teaching Arabic to non-native speakers. To achieve these objectives, the study followed a descriptive approach, and collected the necessary data through an integrated questionnaire prepared for the purpose of describing the phenomenon or topic. This approach was adopted, as it is characterized by being comprehensive, focuses on collecting data related and necessary to the topic under study.
