Performance Improvement of the Implementation of Concrete Structures in the Construction Sector In Iraq Using The Modern Management Technique “Six Sigma”
...Show More Authors

The reality of the field of construction projects in Iraq refers to needing for the development of performance in order to improve quality and reduce defects and errors and to control the time and cost, so there is needing for the application of effective methods in this area, one of the methods that can be applied in this area is the manner of Six Sigma. This research aims to enhance the performance and quality improvement for the construction projects by improving performance in the work of the implementation of the concrete structure depending on the Six Sigma methodology, and for the purpose of achieving the aim of the research, the researcher firstly depends on the theoretical study that include the concepts of quality and the Six Sigma methodology as a system aims to reduce defects and improve the quality and secondly on the field study carried out by the researcher through conducting the open questionnaire that include interviews conducted by the researcher with a slice of engineers experienced in the implementation of construction projects that leads to design closed questionnaire included the major axes of  the research and distributed on a selected sample of engineers with expertise in this area. The researcher applying the (DMAIC) methodology is one of the methods adopted for the application of Six Sigma on the case study (the project of structures laboratory at University of Baghdad) for the purpose of identifying the most important defects that may appear in the implementation of the concrete structure and assess the quality of implementation of the concrete structure and then analyzing the causes of these defects and propose procedures to enhance the performance and quality improvement depending on the field survey was conducted. The most important research conclusions are sigma level for the case study is 2.35 and the number of defects per million opportunities is 211905 and this Sigma level is very small which indicates the low level of quality for the case study.

This study was aimed to explore the impact of a practical program on supporting and reducing
symptoms of school bulling victims in a sample of student in the sixth grade. The study sample consisted of (18)
students that have been chosen from two schools (Al-Abass and Alataa’) it was an intended sample, because
there were enough student with high scores in bulling victims diagnostics test, the sample was divided into two
groups: the control group of (9) student from (Alataa’) school, and the experimental group consisted of (9)
student from Alabass) school keeping in mind to keep the two groups equivalent in maintaining equal controls.
The researcher applied the practical program which is based on cognitive behavioral

Efficacy of Papacarie in Reduction Total Bacterial Count in Comparison with the Conventional Rotary Method
...Show More Authors

Background: The change in the concepts of cavity preparation and the development of reliable adhesive materials lead to the development of alternative methods of caries removal. Chemo-mechanical caries removal (CMCR) involves the chemical softening of carious dentin, followed by its removal with manual excavation. The present study was conducted to evaluate clinically the efficiency of caries removal using a new chemo-mechanical agent (Papacarie) compared to the conventional drilling method in reduction of total bacterial count. Material and methods: The study is a split mouth design. The sample composes from sixty mandibular deciduous molars teeth in thirty children, between six to nine years of age with bilateral class I deep occlusal car

The Role of Chlorella vulgaris in Reducing Some Pharmaceutical Wastes Toxicity in Clam Pseudodontopsis euphraticus
...Show More Authors

Applications of microalgae in environmental studies have recently increased. Current uses of immobilized microalga Chlorella vulgaris include reducing pharmaceutical substances such as amoxicillin AMX and potassium dichromate K2Cr2O7 on freshwater clam Pseudodontopsis euphraticus as a biotic model. Recent research pointed out a change in biomarkers of oxidative stress in an evaluation of induced toxicity. Where clams were exposed to different concentrations100, 200, and 400 mg/L for 7 days and 20, 30, and 50 mg/L for 5 days of amoxicillin and potassium dichromate, respectively. The results showed that exposure to AMX and K2Cr2O7 led to a signific
