The current study was conducted on irrigational project called (Beat Zwena River), located in Jadedat- alshat, within the province of Dyala, which is divided from the right side of the Tigris River, the project significant environmental importance was passed in several agricultural areas estimated about 1600 acres, and it is also used for the purposes of irrigation and drinking. One of the major drawback for the current study is the almost lack data about the physiochemical parameter, in addition to measure (chlorophyll a and phyophtin of the River under investigation, in five locations for the period of October 2013 until June 2014. The range of studied properties was: 10.83 -38.75°C and 9.17 -28.5°C for air and water temperature, water depth (165 - 284.33 cm), light transmittance, (14.5 - 152cm) , turbidity (0.27-106.98) NUT, electrical conductivity, EC,(514.83 - 1027.5) µS/cm , salinity (1.15-4.88 part per thousand), total dissolved solids, TDS (287.83- 861.6) mg/l and total suspended solids TSS (2- 49.87) mg/l, pH (6.25- 7.98), dissolved oxygen, DO (3.65- 11.25)mg/l and biological oxygen demand. BOD5 (1.07- 4.35 mg / l, total alkalinity, TA (115.33- 187.5 ) mg CaCO3/l, total hardness, TH,( 221.83- 338.83) mg CaCO3/l, calcium, Ca (52.08-101.36) mg CaCO3/l, and magnesium , (74.62- 177.89) mg CaCO3 /l, total nitrate NO3(0.20- 6.50) mg /l, effective nitrate NO3 (1.55- 6.55) mg/l and effective phosphate PO4 (0.02 - 4.16) mg/l, sulfate SO4 (131.5- 283)mg/l, chlorophyll a, ( 0.12- 25.65) and Phaeophytin-a, (0.85- 25.93). mg/l, respectively. Results of the study showed that most of the studied characteristics and private (Salinity, EC, TH, PO4, BOD5, Turbidity, TDS and Mg) were once influential or higher rates than permitted environmentally, according to WHO, FAO Organization, as well as the Iraqi specifications for the river water, which show that human activities in the region significant effect on water and environment of project.

Background: Many types of instruments and techniques are used in the instrumentation of the root canal system. These instruments and techniques may extrude debris beyond the apical foramen and may cause post-instrumentation complications. The aim of this study was to evaluate the amount of apically extruded debris resulted by using 4 types of nickel-titanium instruments (WaveOne, TRUShape 3D conforming files, Hyflex CM, and One Shape files) during endodontic instrumentation. Materials and methods: Forty freshly extracted human mandibular second premolar with straight canals and a single apex were collected for this study. All teeth were cut to similar lengths. Pre-weighted glass vials were used as collecting containers. Samples were randoml

This research has come out with that strategies made by Porter as generally strategies applicable to any size and type of economic units cannot be applied to many of the economic units in the world in generally and in Iraq especially not a lot of economic units have the resources and competencies that enable them to provide a unique product of its kind in the minds of customers and then adopt a differentiation strategy and not a lot of economic units have the resources and competencies that make them the cost leader. Differentiators and cost leaders are minority in the world while not differentiators and not cost leaders are majority in the world.
The economic units are not differentiators and not c

In Iraq, more than 1031 school projects have been halted due to disputes and claims resulting from financial, contractual, or other issues. This research aims to identify, prioritize, and allocate the most critical risk factors that threaten these projects’ success for the duration (2017-2022). Based on a multi-step methodology developed through systematic literature reviews, realistic case studies, and semi-structured interviews, 47 risk factors were identified. Based on 153 verified responses, the survey reveals that the top-ranked risk factors are corruption and bribery, delaying the payments of the financial dues to the contractors or sub-contractors, absence of risk management strategy, multiple change orders due
