Physical and Histological Evaluation of Coated Implant with Nano ZrO2 after Creation Titania Nanotubes
...Show More Authors

Background: Contact between implant material and bones must be strong and fast creation, to fulfill these properties appropriate surface modifications must apply on used implants. In this contribution; double surface modifications are applied on Ti-6Al-4V alloy to accelerate osseointegration. Materials and methods: Anodic process is utilized to create titania nanotubes (TNTs) on the screws made from Ti-6Al-4V alloy. These implants were coated with nano ZrO2 particles. Second modification was annealing anodized screws at 8000C, and implanted in tibiae of nine adult New Zealand white rabbits. Results: Physical and histological consequences of two surface modifications on Ti-6Al-4V alloy screws were studied. Scanning electron microscope (SEM) images shows inhomogeneous distribution of TNTs on screws surfaces. X-ray diffraction (XRD) patterns illustrate the covering of first group samples with ZrO2 and transformation of Ti to its oxide (Rutile phase) for second group. These pattern shows that TiO2 had higher crystallinity and larger grain size than ZrO2. Atomic Force Microscopy images (AFM) shows the increasing of roughness, grain size and internal diameter of TNTs after annealing process. Coated implant with ZrO2 at 4 month duration shows threads with newly Haversian canal feature. Annealed implant at same duration shows well developed threads, base of implant illustrates bone trabeculae filled the base of implant bed with active osteoblast cells. Conclusion: Modification of implant's surface produced an improvement of osseointegration in comparison to untreated one.

Influence of Nano Additives on Unconfined Compressive Strength of Asphaltic Soil
...Show More Authors

Collapsible behaviour of soil is considered as one of the major problems in the stability of roadway embankment, the lack of cohesion between soil particles and its sensitivity to the change of moisture content are reasons for such problem. Creation of such cohesion may be achieved by implementation of liquid asphalt and introduction of Nano additives. In this work, silica fumes, fly ash and lime have been implemented with the aid of asphalt emulsion to improve the unconfined compressive strength of the collapsible soil. Specimens of 38 mm in diameter and 76 mm height have been prepared with various percentages of each type of Nano additive and fluid content. Specimens were subjected to unconfined compressive strength determination at dry a

The Thermal Pre-processing Technique of the Bio-waste for Contaminated Water Treatment: Histological and Experimental Study
...Show More Authors

The current study suggested a thermal treatment as a necessary proactive step in improving the adsorption capacity of bio-waste for contaminants removal in wastewater. This approach was based on the experimental and histological investigation of biowaste pods shell. This investigation showed that these shells compose of parenchyma cells that store secondary metabolites compounds produced from cells were exhibited in present study. The results also reported that these compounds are extracted directly from the cells as soon as they are exposed to an aqueous solution, hampering their use as an adsorbent material. The increase in the weight of bio-waste adsorbent at unit liquid volume increases the production of secondary metabolites compounds

The Morphological Description and Histological Structure of the Liver in Marsh Harrier Bird in Iraq (Circus aeruginosus)
...Show More Authors

The liver of marsh harrier grossly appeared as large, bi-lobed organ divided into left and right lobes, which are approximately equal in size and not divided into secondary lobes. Histologically, the liver of marsh harrier was found to contain numerous lobules which are not well defined by the connective tissue of the septa except that surrounded the portal triads. The parenchyma of liver composed of irregular branching cords of hepatocytes organized in double rows alternating with tortures path sinusoids which are lined with flattened endothelial cells and large, irregular outlined kupffer cells. Hepatic cords arranged in a radial pattern around the central vein of the liver lobule while in a subscapsular region they run parallel to the ca

Israeli foreign policy towards Iraq after occupation in 2003
...Show More Authors

Summery of the Study: The Israeli interest in Iraq was not the result of the 2003 US war, which ended with its occupation, but Iraq was still at the top of Israeli concerns, as it was due to its interest and desire to occupy the Zionist movement for a number of reasons, most importantly its religious position in the Jews and control It is a sacred religious duty, so Israel has employed all its organs, institutions, relations and espionage networks in order to penetrate it and perpetuate its existence, and succeeded in achieving its foreign policy objectives at a time when the area was open to it without opposition or competition thanks to its strategic alliance with the states Of the United States of America, which has been able to penet

Phytoplankton primary production in southern Iraqi marshes after restoration
...Show More Authors

Primary productivity and chlorophyll-a were used in this study to monitor the restoration process of southern Iraqi marshes (Al-Hewaizeh, central marshes, and Al-Hammar). The phytoplankton primary productivity was based on oxygen light/dark bottle method. Two different depths samples were taken monthly from six studied marshes stations (two stations for each marsh) during November 2005 to October 2006, while chlorophyll-a samples taken from surface water. The phytoplankton primary productivity values ranged 9.38 – 249.79 mg C/m3.hr for all marshes, its values for surface water sample ranged 11.71 – 256.24 mg C/m3.hr, while for 1m depth ranged 9.38 – 142.5 mg C/m3.hr. Chlorophyll-a values ranged between (1.1 – 21.26) µg/l indicating

Obstacles to achieving societal peace in Iraq after 2018
...Show More Authors

    Community peace is achieved in law-based states Constitutional institutions with competence and powers, and otherwise that peace is shaken and begins to collapse. The movement of individuals and groups in the State is regulated by law The law and its proper application without selectivity or exception, and then the sense of equal opportunity and equal rights grows every citizen looks at his spouse, what he has, and when he is unbalanced, a sense of frustration and stealing of rights is generated Societal peace suffers from the shocks of instability and what is reflected in the surrounding environment. Instead of production, demolition takes place, which impedes the achievement of the required peace.

Abstract Since 2003. Iraq has begun a new phase in its modern history, which was after a long period of tyranny, repression of freedom of expression, and women were no better off than men; they suffered marginalization and exclusion, but after the fall of the former regime and the adoption of a parliamentary system of government, The level of participation in the government; where it approved the share of women in the legislative authority called "quota" which reflects the legislative level of a certain proportion of the seats in Parliament, amounting to 25%, and this is approved by the Iraqi constitution for 2005. But it is noticeable that women in parliament did not work within the quota; in other words they belonged to the pol
