The radiological effects of dust storms in Baghdad- Ramadi area
...Show More Authors

Twelve storm dust samples were collected from three cities in Iraq. The samples were collected in the same time during big storms which hit Iraq in summer, 2012 and 2013.  The deposited dust on 4 by 4 nylon sheet on surfaces of selected buildings in cities of Baghdad, Fallujah and Al-Ramadi were collected. Each sample was put in sealed Marinilli beaker and kept for 4 weeks to reach the equilibrium state between radium and its short half-life daughters. Gamma spectrometry system based on HPGe was used for analysis of natural and artificial radionuclides in the dust. The activities of natural radionuclides were found to be ranged between 13-19 Bq/kg, 9-14 Bq/kg and 200-240 Bq/kg for Ra-226, Th-232 and K-40 respectively, while Cs-137 w

Seismic structural study of Mishrif and Nahr Umr Formations in Huwaiza oilfield south-eastern Iraq
...Show More Authors

An interpretive study of two-dimension seismic data of the Huwaiza oilfield was carried out using Petrel 2015 program. Twenty seismic section were used, these seismic sections were carried out at three-time stages: HH survey in 1976, 2HH survey in 1978 and AM in 1980. Mishrif and Nahr Umr reservoirs were selected to study because they are the most important reservoirs in the neighbor fields. The study showed that the structure is an anticline trending North-South, so that the field may belong to Zubair tectonic subzone rather than Tigris subzone, which is northwest-southeast trending. A hypothetical model was drawn up showing the extension of the field in the Iraqi and Iranian territories based on information from both sides, it showed t

CdS Nps (inorganic material) was prepared by the chemical reaction method. ZnPc (organic material) and CdS thin films were prepared separately to compare their characterization with the hybrid BHJ blend ZnPc/CdS thin film (2ml:2ml) by spin coating technique. The structural and morphological properties of the prepared thin films have been measured by XRD and AFM respectively. The XRD pattern for both as-deposited and annealed CdS nanoparticle films shows a hexagonal structure. The crystallite size behavior of as deposited ZnPc films and annealing at 423K for 1h, 2h and 3h was approximately similar to the behavior of heat treated blended films. The grain size was measured by AFM, which decreaseds with annealing temperature for ZnPc films,

Effect of Ph on the Growth and Survival of Juvenile Common Carp (Cyprinus Carpio L.)
...Show More Authors

Common carp ( Cyprinus carpio L.) juveniles  averaging 7.68± 0.25 - 8.12± 1.14 g in weight were  used for 6 weeks to investigate their survival and growth preferences. The experimented carp were stocked at 12 tanks formerly adjusted with different pH levels values as: 6.0, 7.0, 8.0 and 9.0.  Growth and survival of common carp was assessed every Sunday of each week. Growth rates significantly (P < 0.05 ) increased  at pH 7 and  pH8 respectively. Therefore, the results suggest that the water with pH ranged from 7 to 8 was the best range for growth performance and survival rate of carp. Feed conversion ratio (FCR) improved at pH 6  and 9 respectively. In general, the results indicated that water p

This study proposed to synthesize iron oxide by biological method nanoparticles. The E.coli is used to reduce Ferric chloride salt into iron particles. The formation of iron oxide nanoparticle was initially monitored by visual observation and then characterized with the help of various characterization techniques such as Uv-vis spectroscopy, (AFM) and (FTIR) analysis, which revealed that the biosynthesized iron oxide nanoparticles were spherical within size 27.7 nm. Optimization of iron oxide nanoparticle biosynthesis by E.coli was performed for parameters (temperature and pH) and the results revealed that temperature 37°C and pH 5 were the optimum conditions for iron oxide nanoparticales biosynthesis by E.coli.<

      Laser ablation of a silver target immersed in distilled water using Nd:YAG laser with a fundamental wavelength of 1064nm was carried out to fabricate silver nanoparticles (Ag NPs) with different laser energy in the presence and absence of magnetic field. UV-Visible spectrum showed that the nanoparticles are almost spherical in shape. The number of Ag NPs increased by increasing laser energy while their particle size was reduced by increasing  laser energy without magnetic field. In the presence of magnetic field, the size of Ag NPs increased slightly by increasing laser energy. According to AFM results, the presence of magnetic field did not affect the average diameter of Ag NPs. The presence of a magn

Localization of the Optic Disc in Retinal Fundus Image using Appearance Based Method andVasculature Convergence

Optic Disc (OD) localization is a basic step for the screening, identification and appreciation of the risk of diverse ophthalmic pathologies such as glaucoma and diabetic retinopathy.In fact, the fundamental step towards an exact OD segmentation process is the success of OD localization. This paper proposes a fully automatic procedure for OD localization based on two of the OD most relevant features  of high-intensity value and vasculature convergence. Merging ofthese two features renders the proposed method capable of localizing the OD within the variously complicated environments such as the faint disc boundary, unbalanced shading, and the existence of retinal pathologies like cotton wall and exudates,which usually share the same

Intelligent Bat Algorithm for Finding Eps Parameter of DbScan Clustering Algorithm

    Clustering is an unsupervised learning method that classified data according to similarity probabilities. DBScan as a high-quality algorithm has been introduced for clustering spatial data due to its ability to remove noise (outlier) and constructing arbitrarily shapes. However, it has a problem in determining a suitable value of Eps parameter. This paper proposes a new clustering method, termed as DBScanBAT, that it optimizes DBScan algorithm by BAT algorithm. The proposed method automatically sets the DBScan parameters (Eps) and finds the optimal value for it. The results of the proposed DBScanBAT automatically generates near original number of clusters better than DBScanPSO and original DBScan. Furthermore, the proposed method

The Cytotoxic Effect of Zno Nps Against the Intracellular Amastigotes of Leishmania Donovani in Vitro

Leishmania parasite preferentially infect host phagocytic cells, primarily dendritic cells and macrophages. One of the main problems with Leishmania infections is the capability of these parasites to evade and subvert immune responses of the host. Leishmaniasis is treated with a small arsenal of drugs; all of them have disadvantages in terms of efficacy, high price, toxicity or treatment regimen. In this study, the effect of Zinc oxide nanoparticles (ZnO NPs) was evaluated against intracellular amastigotes Leishmania donovani in vitro conditions. The effect of different concentrations from ZnO NPs (0.18, 0.37, 0.75 and 1.5 μg / ml) was used to study on the viability of amastigotes and macrophages “following infection" using the colori

A Modified Key Scheduling Algorithm for RC4

Rivest Cipher 4 (RC4) is an efficient stream cipher that is commonly used in internet protocols. However, there are several flaws in the key scheduling algorithm (KSA) of RC4. The contribution of this paper is to overcome some of these weaknesses by proposing a new version of KSA coined as modified KSA . In the initial state of the array is suggested to contain random values instead of the identity permutation. Moreover, the permutation of the array is modified to depend on the key value itself. The proposed performance is assessed in terms of cipher secrecy, randomness test and time under a set of experiments with variable key size and different plaintext size. The results show that the RC4 with improves the randomness and secrecy with
