Waste materials might be utilized in various applications, such as sustainable roller compacted concrete pavements (RCCP), to lessen the negative environmental consequences of construction waste. The impacts of utilizing (brick, thermostone, granite, and ceramic) powders on the mechanical characteristics of RCCP are investigated in this study. To achieve this, the waste materials were crushed, grounded, and blended before being utilized as filler in the RCCP. After the mixes were prepared, compressive strength, splitting tensile strength, flexural strength, water absorption, density, and porosity were all determined. According to the research results, adding some of these powders, mainly brick and granite powder, enhances the mechanical characteristics of RCCP due to their pozzolanic activity and filler effect. Compared to the reference mixture, the usage of ceramic powder provided satisfactory results. When the thermostone powder is utilized in RCCP, unfavorable results occur, resulting in a reduction in the RCCP's mechanical characteristics.
This research deals with the idea of a constitutional public order, determining its nature, and its applications in light of the Constitution of the Republic of Iraq for the year 2005, by reviewing the relevant constitutional and legal texts, and comparing them with the principles followed by the Federal Supreme Court on the one hand, as well as comparing the behavior of the Iraqi constitutional legislator with some Comparative trends relevant to this topic, especially in Egypt and France, in order to try to draw a road map related to this idea in Iraqi legislation and jurisdiction.
The importance of the research is the scarcity and lack of in-depth studies by constitutional jurists in Iraq despite their abundance in the wr

As a microbial control agent against Chrysomya albiceps (blow fly) larvae and adults under laboratory conditions. The results revealed that percentages of accumulated mortalities of second instar larvae were 30 - 63.33% for the doses 100 – 2000 ppm respectively , Mortalities rate increased with increased of time, treating larval food with 1000 ppm of bacterial suspension caused mortality rate reached 30% after two days, later reached 72.96% after 12 days. The bio assays results of treating adults food showed that mortalities percentage were 6.67 – 73.33 when their food was tre

Drought and water scarcity made rainwater harvesting one of the main steps toward climate change adaptation. Due to the deterioration of the quality of urban runoff and the increase of impermeable urban land use, the treatment of urban runoff is essential. Best Management Practice (BMP) and Low Impact Development (LID) approaches are necessary to combat climate change consequences by improving the quantity and quality of water resources. The application of Bioswales along urban streets and roadways can reduce the stress on water resources, recharge groundwater and prevent groundwater pollution. While Sulaymaniyah City has a

Show MoreBackground: Primary myelofibrosis is characterized by clonal expansion of hematopoietic stem cell with a non-reactive clonal proliferation of fibroblasts and bone marrow fibrosis, which occurs at an extramedullary hematopoiesis. The clinical features of Primary myelofibrosis include anemia, marked splenomegaly and constitutional symptoms. Ineffective erythropoiesis and extra-medullary hematopoiesis are the main causes of anemia and organomegaly, respectively Objectives : the aim of this study was to evaluate the clinical features, diagnostic tools and the treatment outcome of patients with primary myelofibrosis.
Patients and methods: this is a prospective study conducted at the national center of hematolo
A new mixed ligand complexes have been prepared between 8- hydroxy quinoline and o-hydroxybenzylidene-1-phenyl-2,3-dimethyl-4-amino-3-pyrazolin-5-on with Mn(II),Fe(II),Co(II),Ni(II) and Cu(II) ions . the prepared complexes were isolated and characterized by (FT-IR)and (UV-Vis) spectroscopy. Elemental analysis (C.H.N) Flame atomic absorption technique . in addition to magnetic susceptibility and conductivity measurement.
In recent years, the attention of researchers has increased of semi-parametric regression models, because it is possible to integrate the parametric and non-parametric regression models in one and then form a regression model has the potential to deal with the cruse of dimensionality in non-parametric models that occurs through the increasing of explanatory variables. Involved in the analysis and then decreasing the accuracy of the estimation. As well as the privilege of this type of model with flexibility in the application field compared to the parametric models which comply with certain conditions such as knowledge of the distribution of errors or the parametric models may

This study has came as a result to discover on the references of the educational theories which leads the professors in the educational art departments in the Iraqi universities through knowing these ideological references indeed in an important slice of the society. This slice is: the members of professoriate. The study goal knows the ideological references to these theories for the professors in these departments.
In order to approve the research's goals. The researcher has selected a sample contains (50) professoriate members in these departments in the Iraqi universities which they have the educational art profession among the next scientific degrees (assistant teacher. teacher. assistant professor & professor).

This hydrochemical study of the surface and groundwater in Khan AL-Baghdadi area, western Iraq, included the interpretation of physical, chemical, and biological properties. Water samples were collected from wells (14 samples) and surface water of Euphrates River (6 samples) for the dry and wet periods of October 2018 and April 2019, respectively. The stable isotopes analysis was performed for the dry period only. The surface water samples were characterized by slightly alkaline, fresh, excessively mineralized, Ca-chloride type, and hard to very hard water class. While the groundwater samples were characterized by slightly alkaline, brackish, excessively mineralized, Ca-chloride and Na-Chloride type, and hard to very hard wat
