An Environmental Study on Phytoplankton (Diatoms) in Al-Yusifiya River, Iraq
...Show More Authors

An environmental study conducted on diatoms in Al Yusifiya river beyond its branching from Euphrates river. Four sites were selected along the river for the period from march 2013 to September 2013. The present study involved the measurement of physicochemical parameters, also the qualitative and quantities of diatoms. The studied parameters values ranged as follows: 19-44Cº and 16-30 Cº for air and water temperature respectively, 6.9-8.7, 595-1248 µS/cm, 6.4-8.0 mg/l for pH, electric conductivity and dissolved oxygen respectively. A total of 74 taxa were recorded for diatoms, where the pinnate diatom was the predominant and recorded 64 taxa while 10 taxa for centric diatoms. The total number of diatoms was 1197.55*104 cell /l. The total number values were ranged as follows:( 28.3-48.6) *104 cell /l in the first site ,( 33.6-51.5) *104 cell /l in the second site,( 39.8-67.2) *104 cell /l in the third site and ( 22.3-38.0) *104 cell /l in the fourth site. Two species Asterionellaformosa Hassall and Diploneispuella Schumann were noticed in site 2 only, while C. prostateBerkeleyfound in all studied sites expect in site 1. StephaenodicushantzschiiGrunow and Didymosphenia geminate (lyngb.) Schmidtwere recorded in sites 1 and 3, Anomoeoneissp was recorded in sites 1 and 4 only. The Mastogloiasp was noticed only in sites 2 and 4.

A Comparative Study to Reveal Earnings Management in Emerging Markets: Evidence from Tunisia and Iraq
...Show More Authors

Purpose: The purpose of the study is to compare and evaluate Earnings Management in Tunisia and Iraq.   Theoretical framework: Earnings Management is an important topic that has been studied by a significant number of researchers, as well as those who are interested in the accounting profession. Earnings Management has gotten a lot of attention from academics, professionals, and other interested parties in recent years (e.g. Kliestik et al., 2020; Rahman et al., 2021; Gamra &Ellouze, 2021)   Design/methodology/approach: The sample includes ten banks listed on the Bourse of Tunisia and Iraq Stock Exchanges for the year 2017. We have used a model of Kothari et al., (2005) as a tool to measure Earnings Management in both mark

Seismic structural study of Mishrif and Nahr Umr Formations in Huwaiza oilfield south-eastern Iraq
...Show More Authors

An interpretive study of two-dimension seismic data of the Huwaiza oilfield was carried out using Petrel 2015 program. Twenty seismic section were used, these seismic sections were carried out at three-time stages: HH survey in 1976, 2HH survey in 1978 and AM in 1980. Mishrif and Nahr Umr reservoirs were selected to study because they are the most important reservoirs in the neighbor fields. The study showed that the structure is an anticline trending North-South, so that the field may belong to Zubair tectonic subzone rather than Tigris subzone, which is northwest-southeast trending. A hypothetical model was drawn up showing the extension of the field in the Iraqi and Iranian territories based on information from both sides, it showed t

A Comparative Reservoir Study of Zubair and Nahr Umr Formations in Subba Oilfield, Southern Iraq
...Show More Authors

The lower Cretaceous sandstones of Zubair and Nahr Umr formations are the main producing reservoirs in Subba oilfield in southern Iraq. Key differences in their petrophysical and depositional attributes exist affecting their reservoir characteristics. The evaluation of well logs and core porosity-permeability data show better reservoir properties in Nahr Formation. The Litho-saturation logs indicate greater thickness of oil-saturated reservoir units for Nahr Unr Formation associated with lower values of shale volume, and higher values of effective porosity. In addition, higher values of permeability for Nahr Umr Formation is suggested by applying porosity-irreducible water saturation cross plot. The reducing reservoir quality of Zub

Algal study in the springs and streams from Shaqlawa district, Erbil Province, Iraq II- Zygnematales
...Show More Authors

Zygnematales an order of green algae in Shaqlawa District Erbil, Kurdistan Region, Iraq, has been studied in eighteen sites, distributed between twelve springs and six along the streams within Shaqlawa district from September2019 to August2020. A total of 116 species belonging to 9 genera were identified. The most dominant genera included Spirogyra and Cosmarium (31, 30) taxa respectively. Out of them, 30 species were recorded for the first time in Iraq. Newly found genera included one species each for Cylindrocystis, Debarya, Hallasia and Staurastrum, nine species belonged to Mougeotia

A chemotaxonomical Study of Four Species Belonging the Genus Arabis L. Cruciferae (Brassicacae) in Iraq
...Show More Authors

This study has been focused on the detection of phenolic compound in aerial parts (stem and leaves)of the species belonging the genus Arabis L. A.Caucasica Willd, A.Sagittata (Bertol)DC, A.Aucheri Boiss, A.nova Vill of family cruciferou (Brassicaceae) which were collected during field trips of the districted of Iraq. Phenolic compounds have been identified by using High Performance Liquid Chromatography (HPLC). Nine standard compounds used for comparison five of them flavonoids ( Rutin, Quercetin, kaempferol, Luteolin and Apigenin) and the other phenolic acid ( Chlorogenic acid, Caffeic acid, Ferulic acid and Rosmarinic acid) , results showed that species vary in containing phenolic compound which can be counted as a taxonomic evidence s

Causes of Problems in Post-Disaster Emergency Re-Construction Projects—Iraq as a Case Study
...Show More Authors

This study examines the causes of time delays and cost overruns in a selection of thirty post-disaster reconstruction projects in Iraq. Although delay factors have been studied in many countries and contexts, little data exists from countries under the conditions characterizing Iraq during the last 10-15 years. A case study approach was used, with thirty construction projects of different types and sizes selected from the Baghdad region. Project data was gathered from a survey which was used to build statistical relationships between time and cost delay ratios and delay factors in post disaster projects. The most important delay factors identified were contractor failure, redesigning of designs/plans and change orders, security is

3D Seismic Structural and Stratigraphy Study of Shuaiba Formation in Kumait Oil Field-Southern Iraq
...Show More Authors

The Kumait Oil field was interpreted using 3-D seismic data from Oil Exploration company. The Shuaiba Formation (Cretaceous Age) reflector is detected.Structural map of formation is prepared to obtain the location and direction of  the sedimentary basin and shoreline. Depth maps was drawn depending on the structural interpretation of  the picked reflector and show several structural feature as closures.The seismic interpretation of the area approves the presence of some stratigraphic features in the studied formation. Some distributary mound and flatspot were observed within the study area, but they are not continuous due to the tectonic effects. These activity elements give reasonable explanation for the hydrocarbon distributi

A particulate polymer composite material was prepared by reinforcing with the Aluminum Oxide (Al2O3) or Aluminum (Al) metallic particles with a particle size of (30) µm to an unsaturated Polyester Resin with a weight fraction of (5%, 10%, 15%, 20%).

Tensile test results showed the maximum value of elastic modulus reached (2400MPa.)  in the case of reinforcing with (Al) particles with weight fraction (20%) and (1500 MPa.)  in the case of reinforcing with (Al2O3) particles of the same weight fraction.

  When the impact and the flexural strength tests were done, the results showed that flexural strength (F.S), maximum shear stress (τmax), impact strength
