This work involved the co-substitution of the two bioactive ions of strontium and magnesium into the hydroxyapatite (HA) coating which was then electrochemically deposited on Ti-6Al-4V ELI dental alloy (Gr.23) before and after treatment by Micro Arc Oxidation (MAO). The deposited layers were characterized by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FTIR). The adhesion strength of the coating layer was estimated by using pull-off adhesion test. The adhesion strength of Sr/Mg-HA on the Ti-6Al-4V ELI dental alloy after MAO treatment was 1.79 MPa, which was higher than that before MAO treatment (1.62 MPa). The corrosion behavior of the alloy in artificial saliva environment at temperature ranged 293-323K was assessed by means of electrochemical techniques and potentiodynamic polarization curves. The corrosion protection to the alloy at 293K was increased from 67.98% before treatment by MAO to 75.87% after treatment. The antimicrobial properties of the coated alloy were evaluated against different bacteria and oral fungi (Candida).

Thyroid carcinoma incidence is increasing year after year and ranking second among top ten cancers in Iraq, especially among women, and this increased the requirement for the improvement of the molecular detection accuracy because of its potential role in the early detection. Two single nucleotide polymorphisms (rs1136410, A>G and rs1805414, A>G) in PARP1 gene were found to be associated with thyroid carcinoma risk in several genome wide association studies, therefore, this is a case-control study that was carried out to identify whether these polymorphisms are associated with papillary thyroid carcinoma risk in Iraqi population. The Association was investigated in one hundred and one papillary thyroid carcinoma patients (11 male and 90 female) with ages (22-65), and one hundred and two controls (16 male and 86 female) with ages (21-67), using quantitative PCR-high resolution melting technique. The results showed that there is a strong association between both of rs1136410and rs1805414 with papillary thyroid carcinoma, the allele G was significantly associated with the disease as a risk factor in both variations (p<0.0001, odd ratio(OR): 4.9635, 95% confidence interval(CI): 3.2179-7.6560) in rs1136410, and (P<0.0001, odd ratio(OR): 3.1620, 95% confidence interval (CI): 2.0997-4.7619) in rs1805414. while the allele A represents a protective factor in both variations (OR=0.2015 and 0.3163 respectively). In conclusion, the allele G in both rs1136410 and rs1805414 in the PARP1 gene is strongly associated with papillary thyroid carcinoma in the Iraqi population.

Thyroid carcinoma incidence is increasing yearly and ranks second among the top ten cancers in Iraq, especially among women. The single nucleotide polymorphism (rs965513, A>C) near FOXE1 gene was found to be associated with papillary thyroid carcinoma risk in several Genome-wide association studies. Therefore, this is a case-control study aimed at identifying whether this variation is associated with the risk of papillary thyroid carcinoma in the Iraqi population. Association of rs965513 was investigated in one hundred and one papillary thyroid carcinoma Iraqi patients and one hundred and two controls using quantitative PCR-high resolution melting technique. The results of genotype and allele frequencies showed that there is a strong association between rs965513 and papillary thyroid carcinoma. The allele C was significantly associated with the disease as a risk factor (P < 0.0003, odd ratio (OR): 2.1014, 95% confidence interval (CI): 1.3987-3.1570), while the allele A represents a protective factor (OR=0.4759). In conclusion, the allele C in rs965513 near FOXE1 gene is strongly associated with papillary thyroid carcinoma in the Iraqi population.

Chromium oxide (Cr2O3) doped ZnO nanoparticles were prepared by pulsed laser deposition (PLD) technique at different concentration ratios (0, 3, 5, 7 and 9 wt %) of ZnO on glass substrate. The effects of ZnO dopant on the average crystallite size of the synthesized nanoparticles was examined By X-ray diffraction. The morphological features were detected using atomic force microscopy (AFM). The optical band gap value was observed to range between 2.78 to 2.50 eV by UV-Vis absorption spectroscopy, with longer wavelength shifted in comparison with that of the bulk Cr2O3 (~3eV). Gas sensitivity, response, and recovery times of the sensor in the presence of NH3 gas were studied and discussed. In the present work, we found that the sensitivity was increased upon increasing the concentration ratio from 3 to 5%wt of ZnO, whereas it was decreased again over that value. Also, we found that the sensitivity was increased when increasing operating temperature, while the response time was decreased. The optimum concentrations ratio for NH3 gas sensitivity at 5%wt ZnO revealed sensitivity of 66.67% and response time of 14s at operating temperature of 300oC and 700mJ PLD energy.

In today's era of advanced weapons and technology development, many remarkable inventions have shifted the balance of war towards the strategically enhanced military equipped with tactical weapons and armaments. One of these strategic advancements is stealth technology due to which stealth aircraft are high in demand for the military. The question that rises is How to detect a stealth object? This paper proposes a novel anti-stealth technique using void detection, high frequency wave interference and neutrino beam propagation. Void detection method uses a modified satellite-based radar that searches for areas in the aerospace from which the transmitted signals sent to the ground receiving station are blocked or deflected. High frequency wave interference method is used to generate a stellar trajectory of the stealth aircraft at the detected void. Neutrino beam comprises of energy quanta mainly neutrinos, which are able to surpass the absorption or deflection systems in the stealth body of aircraft. This unique phenomenon produces a moving image, which is the precise location of the aircraft in the space. Using these methods, the trajectory of the aircraft is detected which ultimately leads to the detection of the stealth aircraft itself. The newly proposed methods which are theoretically more reliable than the existing methods may not have been tested but the method planning make them practically feasible considering that the technology used is a part of advanced engineering today.

­The development and prosperity of Small and Medium Enterprises (SMEs) are crucial to the development agenda of any economy in the world, be it in developed or developing countries. This is especially so for Muslim countries, most of which fall under low-income countries. Literature is replete with the roles and importance of Small and Medium enterprises in the development of any nation. These include, among others, the creation of employment, source of innovation, export generation, income generation, poverty alleviation, and the source of future medium and large enterprises. There isn't a unanimous definition of SMEs anywhere in the world, and Muslim countries are not an exception. Thus, there exist various definitions of SMEs in Muslim countries. Small and Medium Enterprises have been defined traditionally based on several indexes: number of employees; amount invested; total assets; sales turnover and production capacity. However, the definition based on the number of employees is common in most of the Muslim nations. The SMEs sectors in Iran play a very vital role in economic development and entrepreneurship growth because the SMEs sector is private. In this paper, we find that the main causes of the problems and issues of the SMEs sector are based on a lack of entrepreneurship talents and training because of the factors hindering innovation. We try to find out the role of government-based training institutes and as well as semi-government institutes in entrepreneurship development in the SMEs sector in Iran.

The applications of unmanned aerial vehicles have been extended through the recent decades and they are utilized for both civil and military applications. The urge to utilize unmanned aerial vehicles for civil purposes has elevated researchers and industries interest towards the mini unmanned aerial vehicle (MUAV) category due to its suitable configurations and capabilities for multidisciplinary civil purposes. This study is an effort to further enhance the aerodynamic efficiency of MUAVs through a parametric study of the wing and proposing an innovative bioinspired wing design. The research is conducted utilizing numerical simulation and experimental validation. This research provides a better understanding of different wing parameter(s) effect on the aerodynamic performance of the wing and mini unmanned aerial vehicles. A new wing configuration is designed, implemented and evaluated. The wing is named as Alpine since it is inspired by biomimicry of alpine swift bird. Evaluation of the new wing geometry shows that the Alpine wing geometry performs 35.9% more efficient compared to an existing wing with similar wing area. Hence, the aerodynamic efficiency optimization is achieved for the Alpine wing which helps to enhance the performance of MUAVs.

International Journal of Advanced Computer Science and Applications(IJACSA), 8(1), 2017 ; During the last decade, enormous volumes of urban data have been produced by the Government agencies, the NGOs and the citizens. In such a scenario, we are presented with a diverse sets of data which holds valuable information. This information can be extracted and analyzed and have a number of usages for the well-being of citizens. The major impediment to achieve this goal is the data itself, the available data are redundant, scattered and come with various legacy formats. Data interoperability, scalability and integration are paramount issues which could not be resolved unless the scattered data silos are accessible with a standard representation. In this paper, we propose a framework that resolves the data interoperability and associated challenges in the smart city environment. The framework takes the raw smart city data from several resources and stores them in a NoSQL database. The framework transforms the scattered data into machine-processable data. Besides, the database is linked with an API and simple dashboard for further analysis, which can be utilized to build big data applications based on urban data so that government agencies can get a summarized overview of resource distribution. ; http://thesai.org/Downloads/Volume8No1/Paper_10-An_Interoperable_Data_Framework_to_Manipulate_the_Smart_City_Data.pdf
