Improvement the corrosion Behavior of Titanium by Nanotubular Oxide in a simulated saliva solution
...Show More Authors
Abstract<p>The corrosion behavior of Titanium in a simulated saliva solution was improved by Nanotubular Oxide via electrochemical anodizing treatment using three electrodes cell potentiostat at 37°C. The anodization treatment was achieved in a non-aqueous electrolyte with the following composition: 200mL ethylene glycol containing 0.6g NH4F and 10 ml of deionized water and using different applied directed voltage at 10°C and constant time of anodizing (15 min.). The anodized titanium layer was examined using SEM, and AFM technique.</p><p>The results showed that increasing applied voltage resulted in formation titanium oxide nanotubes with higher corrosion resistance (more positive value of the corrosion potential). The results revealed that good adhered well-ordered vertically aligned titania nanotubes with inner tube diameter of 82nm an mean length of 3microns could be obtained at 30VDC. Low corrosion current density (579 nA.cm-2) and corrosion potential equal to (-209 mV) were observed for untreated titanium metal while a dramatic fall down of the corrosion current was observed for nanotubes TiO2 (76 nA.cm-2) and more positive value of corrosion potential (-138 mV) was observed revealing good corrosion resistance of the improved titanium in saliva solutions.</p>

A Study of Collocation in English
...Show More Authors

We used to think of grammar as the bones of the language and vocabulary as the flesh to be added given that language consisted largely of life generated chunks of lexis. This “skeleton image” has been proverbially used to refer to that central feature of lexis named collocation- an idea that for the first 15 years of language study and analysis gave a moment‟s thought to English classroom material and methodology.
The work of John Sinclair, Dave Willis, Ron Carter, Michael McCarthy, Michael Lewis, and many others have all contributed to the way teachers today approach the area of lexis and what it means in the teaching/learning process of the language. This also seems to have incorporated lexical ideas into the teaching mechanis

Nesfatin-1 is a biomarker that plays a role in the inflammatory process of coronary artery diseases in Iraqi patients with non-alcoholic fatty liver disease.
...Show More Authors

Amis: NAFLD is considered to be the most common cause of liver conditions worldwide. Also, it is a primary reason that leads to coronary artery diseases, limiting blood flow to the heart. Therefore, This study aimed to evaluate the serum level of Nesfatin-1 and its ability to indicate the prognosis of CAD in patients with NAFLD. Material & Methods: one-hundred eighty Individuals were enrolled in the study, including In both genders, blood was collected from each Individual and sent to the laboratory for biochemical tests. Findings: Data from the current study showed a significant increase in Nesfatin-1 in the CAD group and a significant decrease in Nesfatin-1 in the NAFLD group compared to the control group. In addition, there w

The impact of population density in sustainable housing - An applied study in the city of Baghdad (Mahalla 817), Al-Bayaa as a model
...Show More Authors

Population density represents an important indicator for determining the growth of the size of urban areas. Population density has a direct impact on the quality of life, and its excessive rise may lead to the deterioration of basic service facilities. The problem of the research is that the increase in the total population densities of the residential neighborhood may reflect negatively on the nature of the services provided to the residents in these shops, and thus the failure to achieve sustainability in the residential locality. The research assumes that the increase in population densities negatively affects the achievement of sustainability in the residential neighborhood.
