Analysis Of Sedimentation In Trunk Sewer With Laboratory Investigation Of Sewage Sediment Characteristics In Baghdad City
...Show More Authors

Sediment accumulated in sewers is a major concern source as it induces numerous operational and environmental problems. For instance, during wet weather flow, the re-suspension of this sediment accompanied by the combined sewer overflow may cause huge pollutant load to the receiving water body. The characteristics of the sewer sediment are important as it shapes its behaviour and determines the extent of the pollution load. In this paper, an investigation of sewer sediment and its characterization is done for a case study in Baghdad city. Sediment depth covers more than 50% of the sewer cross-sectional area; several operational causes are comprised to cause this huge depths of sediment depositions. The testing and analysis of the sediment showed that the median particle size of the sediment is 0.3 mm, which infer a poorly graded sandy sediment in accordance with the unified classification system, particle’s specific gravity to be 2.63; with a water content of 41%. The organic content is tested and found to be 32.45 g per kg of sediment (equivalent to 3.24%).

Epidemiological characteristics of women with cervical erosion in Al-Sader city, Baghdad, Iraq.
...Show More Authors

Background: Cervical erosion (CE) is a common finding on routine pelvic examination during the fertile years. Published articles on CE in Iraq are scarce; therefore this study was carried out.
Methods: A total of 100 non pregnant women had CE attending a private clinic in Al-Sader city, Baghdad, was included in this study. Pelvic examination was done; demographic data and gynaecological history were obtained.
Results: The age of women was 27.1 ± 5.9 years with 7.3 ±2.9 educational years. Mucopurlent vaginal discharge was a complaint in 49% of women, and a watery vaginal discharge was a complaint in a similar percent. Thirty four of women were oral contraceptive users and 11% were using intrauterine c

Some Protozoan Species Inhabiting the East Bank Sediment of River Tigris in Baghdad City
...Show More Authors

There are no researches in Iraq concerned identification and ecology of protozoa in sediment. The present study has been dealt with free-living protozoa community of the Tigris river bank sediment in Baghdad city. Variable species of vegetation (reeds and wild grasses) were observed to grow at both sides of the river.
For the present study three sites were chosen at the east side of river Tigris. Monthly samples were collected from the sediment of each site over a period from January to October 2012.Total of 22 taxa were found, 12 of ciliates, 5 of each flagellates and sarcodines in the sediment samples. The highest numbers of protozoan 15 taxa were recorded from each of the sites 1&3 and little less taxa (13) were found in site 2

Investigation of Microbial Contamination of Primary Schools in Baghdad City
...Show More Authors

A microbial contamination of several primary schools (official and private) in
Baghdad city was conducted. Sampling was performed in each school from desk,
door handle, and hand of students.
Out of 113swabs (classes desk, door holder, and students hands ) obtained from
ten primary schools, growth wasobserved in 91 samples (80.5%) (for official
school 84.6% and 71.4 for private school.
The results of recent study revealed that the official schools showed higher
contamination levels(130 CFU ) than private ones (90 CFU).
Resultes revealed that a total of 12 morphologically different bacterial species
were isolated from 62 bacterial isolates,among which gram negative bacteria 40
isolates(64.5%) were higher than

Statistical Analysis of Extreme Rainfall Data in Baghdad City
...Show More Authors

Studying extreme precipitation is very important in Iraq. In particular, the last decade witnessed an increasing trend in extreme precipitation as the climate change. Some of which caused a disastrous consequences on social and economic environment in many parts of the country. In this paper a statistical analysis of rainfall data is performed. Annual maximum rainfall data obtained from monthly records for a period of 127 years (1887-2013 inclusive) at Baghdad metrology station have been analyzed. The three distributions chosen to fit the data were Gumbel, Fréchet and the generalized Extreme Value (GEV) distribution. Using the maximum likelihood method, results showed that the GEV distribution was the best followed by Fréchet distribut

Geospatial Data Analysis of School Distribution in Baghdad City
...Show More Authors

     Education and lifelong learning are necessary components of daily city life for urban communities to encourage sustainable and positive communities. The study attempts to analyze the actual school distribution patterns and densities in Baghdad, the Iraqi capital. The significance of this study is that it is associated with one of the essential aspects of humanity: the improvement and affluence of schooling; it impacts school attendance limitations and educational evolution. The education process has been inextricably tied to students' timely and orderly entrance to their schools. Hence the decision maker and planner are concerned by this. The statistics examined elementary and high schools, and the investigated

Epidemiology, Clinical characteristics, Laboratory Findings Of Bronchiolitis In Hospitalized Children
...Show More Authors

Background: Bronchiolitis is the most common disease of the lower respiratory tract during the first year of life. Which is usually caused by respiratory syncytial virus. The treatment is usually supportive, so epidemiology, clinical, laboratory, and radiologic findings might facilitate early diagnosis and treatment of bronchiolitis cases.

Objectives: The aim of our study was to evaluate the clinical characteristics and laboratory findings of children hospitalized due to bronchiolitis.

Patients and Methods: In this cross sectional study 143 patients with bronchiolitis were selected who age 1-24 months old who were admitted to the Fallujah teaching hospital for women and c

Laboratory Investigation on Roller Compaction Technique in Concrete Construction
...Show More Authors

Roller compacted concrete (RCC) is a concrete compacted by roller compaction. The concrete mixture in its unhardened state must support a roller while being compacted. The aim of this research work was to investigate the behavior and properties of roller compacted concrete when constructed in the laboratory using roller compactor manufactured in local market to simulate the field conditions. The roller compaction was conducts in three stages; each stage has different loading and number of passes of the roller. For the first stage, a load of (24) kg and (5) passes in each direction had been employed. For the second stage, a load of (104) kg and (10) passes in each direction were conducted. Finally, at the third stage, a load of (183) kg a

Aquatic Oligochaeta (Annalida:Clitellata) as Bio Indication for Sediment Quality Assessment in Tigris River Within Baghdad City /Iraq
...Show More Authors

Aquatic Oligochaeta is an important group of Macroinvertebrates that has been very remarkable as bioindicators for assessing water pollution and determining its degree in water bodies. Hence, the idea of the current study aims at studying the impact of Baghdad effluents on the Tigris River by using oligochaetes community as bioindicators . For this purpose, four sites along the inside of Baghdad has been chosen. Site S1 has been located upstream, site S2 and S3 has been at midstream and site S4 at the downstream of the River.This investigation has used different types of biological indicators, including the  percentage of oligochaeta  within benthic invertebrates, which ranged from 49.2-51.28%.

     Influent Flow Rate Effect On Sewage Pump Station Performance Based On Organic And Sediment Loading
...Show More Authors

The performance of sewage pumps stations affected by many factors through its work time which produce undesired transportation efficiency. This paper is focus on the use of artificial neural network and multiple linear regression (MLR) models for prediction the major sewage pump station in Baghdad city. The data used in this work were obtained from Al-Habibia sewage pump station during specified records- three years in Al-Karkh district, Baghdad. Pumping capability of the stations was recognized by considering the influent input importance of discharge, total suspended solids (TSS) and biological oxygen demand (BOD).  In addition, the chemical oxygen demands (COD), pH and chloride (Cl). The proposed model performanc
