Staphylococcus Sp.is the most common type of bacteria found in contamination place, we design this study to compare the contamination accident between two hospitals in Baghdad.One of them isthe Burns Specialist Hospital in the Medical CityinRusafa and another one is Al-Karama Hospital in Karkh. The samples were collected fromOperativeWard No1 (OW1), Operative Ward No2 (OW2), Consulting Pharmacy (CP), Emergency Room (ER), Reception Room (RR), Women's Ward (WW) and Men's Ward (MW).The samples were taken from inside each clinical unit, surfaces, food, and air. The results showed that the number of samples containing Staphylococcus sp. bacteria is 81, including 45 belonging to Al-Karama Burns Ward Hospital and 36 belonging to the Medical City Hospital, Burns Special Hospital. The results of Medical City Hospital showed that Staphylococcus sp.isolates resist many antibiotics, 99.99% of the isolatesfrom patient samples were resistant to(CLR, P, AMP); 92.30% of the isolates from air samples were resistant to(P, MET) and 85.71%of isolates from surfaces and food samples were resist for (AMP, MET). Also the results of Al-KaramaHospital showed that the highest resistance in the staphylococcus sp.isolateswere in patient samplesfor (AMP, SXT), in surface samples for (E), in food samples for (E,P) and in air samples for (P) and the resistance rates were 100% to all these antibiotics.

The pancreatic ductal adenocarcinoma (PDAC), which represents over 90% of pancreatic cancer cases, has the highest proliferative and metastatic rate in comparison to other pancreatic cancer compartments. This study is designed to determine whether small nucleolar RNA, H/ACA box 64 (snoRNA64) is associated with pancreatic cancer initiation and progression. Gene expression data from the Gene Expression Omnibus (GEO) repository have shown that snoRNA64 expression is reduced in primary and metastatic pancreatic cancer as compared to normal tissues based on statistical analysis of the in Silico analysis. Using qPCR techniques, pancreatic cancer cell lines include PK-1, PK-8, PK-4, and Mia PaCa-2 with different levels of snoRNA64, including PK-1, PK-8, PK-4, and Mia PaCa-2. The level of expression is correlated with the cell line epithelial or mesenchymal characteristics. Cell lines displaying epithelial characteristics such as PK-1, PK-8 show high levels of snoRNA64 meanwhile, cell lines displaying mesenchymal characteristics such as PK-4, Mia PaCa-2 show low levels of snoRNA64. The level of expression is correlated with the cell line epithelial or mesenchymal characteristics. After knocking down the PK-8 with high snoRNA64 expression, the epithelial markers E. cadherin (E-cad) and Cytokeratin-8 (CK-8) are decreased, while mesenchymal markers Vimentin (Vim), Cytokeratin-19 (CK-19), Metalloprotease -2 (MMP-2), and Metalloprotease-3 (MMP-3) are activated. Those changes suggest that PK-8 responding to the snoRNA64 knock down protocol and increase in mesenchymal function. Together, snoRNA64 expression may participate in epithelial to mesenchymal transition (EMT) and mesenchymal to epithelial transition (MET), in which during metastasis these processes are crucial. In addition, snoRNA64 may be considered as a potential diagnostic biomarker for both early and invasive stages of PDAC. And due to its gradual expression decreases, it may be considered a barrier in tumor progression.

Chromatographic and spectrophotometric methods for the estimation of mebendazole in pharmaceutical products were developed. The flow injection method was based on the oxidation of mebendazole by a known excess of sodium hypochlorite at pH=9.5. The excess sodium hypochlorite is then reacted with chloranilic acid (CAA) to bleach out its color. The absorbance of the excess CAA was recorded at 530 nm. The method is fast, simple, selective, and sensitive. The chromatographic method was carried out on a Varian C18 column. The mobile phase was a mixture of acetonitrile (ACN), methanol (MeOH), water and triethylamine (TEA), (56% ACN, 20% MeOH, 23.5% H2O, 0.5% TEA, v/v), adjusted to pH = 3.0 with 1.0 M hydrochloric acid. Naphazoline nitrate was used as an internal standard. The absorption of mebendazole was measured using a variable wavelength UV detector at 290 nm. Linearity was obtained in the concentration range of 1-60 and 0.10-3.0 mg/L for the HPLC and FIA, respectively. The methods were applied successfully for the assay of mebendazole in pharmaceutical products and no interferences were observed from the common excipients usually used. The proposed methods were validated for their accuracy and precision.

Administrative procedures in various organizations produce numerous crucial records and data. These records and data are also used in other processes like customer relationship management and accounting operations.It is incredibly challenging to use and extract valuable and meaningful information from these data and records because they are frequently enormous and continuously growing in size and complexity.Data mining is the act of sorting through large data sets to find patterns and relationships that might aid in the data analysis process of resolving business issues. Using data mining techniques, enterprises can forecast future trends and make better business decisions.The Apriori algorithm has been introduced to calculate the association rules between objects; the primary goal of this algorithm is to establish an association rule between various things. The association rule describes how two or more objects are related.We have employed the Apriori property and Apriori Mlxtend algorithms in this study and we applied them on the hospital database; and, by using python coding, the results showed that the performance of Apriori Mlxtend was faster, and it was 0.38622, and the Apriori property algorithm was 0.090909. That means the Apriori Mlxtend was better than the Apriori property algorithm.

In this work, functionally graded materials were synthesized by centrifugal technique at different volume fractions 0.5, 1, 1.5, and 2% Vf with a rotation speed of 1200 rpm and a constant rotation time, T = 6 min . The mechanical properties were characterized to study the graded and non-graded nanocomposites and the pure epoxy material. The mechanical tests showed that graded and non-graded added alumina (Al2O3) nanoparticles enhanced the effect more than pure epoxy. The maximum difference in impact strength occurred at (FGM), which was loaded from the rich side of the nano-alumina where the maximum value wasat 1% Vf by 133.33% of the sample epoxy side. The flexural strength and Young modulus of the functionally graded samples were enhanced by 43.69% and 52.74%, respectively, if loaded from the alumina-rich side. On the other hand, when loading (FGM) from the epoxy side, the amount of decrease in bending resistance was 122.4% while the improvement in bending modulus was 81.11% compared to pure epoxy. Scanning electron microscopy (SEM) revealed the fracture surface of the impact samples and the gradient scattering of nanoparticles in the epoxy matrix. Numerous applications can be used to manufacture the functionally graded material by centrifugal casting method, including for the manufacture of gears and all bending applications such as leaf springs.

Wireless Sensor Networks (WSNs) are promoting the spread of the Internet for devices in all areas of life, which makes it is a promising technology in the future. In the coming days, as attack technologies become more improved, security will have an important role in WSN. Currently, quantum computers pose a significant risk to current encryption technologies that work in tandem with intrusion detection systems because it is difficult to implement quantum properties on sensors due to the resource limitations. In this paper, quantum computing is used to develop a future-proof, robust, lightweight and resource-conscious approach to sensor networks. Great emphasis is placed on the concepts of using the BB84 protocol with the AES algorithm in WSN security. The results of analysis indicated a high level of security between the data by depending on the generation of secure keys, and reached an accuracy rate of about (80-95) % based on using NIST statistical. The efficiency of the work increased to 0.704 after using the Quantum Bit Error Rate equation, eventually increasing the network performance. This results in the reduction of the overall amount of energy, and the time required for performing the key exchange in the encryption and decryption processes decreased.

Due to its importance in physics and applied mathematics, the non-linear Sturm-Liouville problems witnessed massive attention since 1960. A powerful Mathematical technique called the Newton-Kantorovich method is applied in this work to one of the non-linear Sturm-Liouville problems. To the best of the authors’ knowledge, this technique of Newton-Kantorovich has never been applied before to solve the non-linear Sturm-Liouville problems under consideration. Accordingly, the purpose of this work is to show that this important specific kind of non-linear Sturm-Liouville differential equations problems can be solved by applying the well-known Newton-Kantorovich method. Also, to show the efficiency of applying this method to solve these problems, a comparison is made in this paper between the Newton-Kantorovich method and the Adomian decomposition method applied to the same non-linear Sturm-Liouville problems under consideration in this work. As a result of this comparison, the results of the Newton-Kantorovich method agreed with the results obtained by applying Adomian’s decomposition method.

Biodiesel can be prepared from various types of vegetable oils or animal fats with the aid of a catalyst. Calcium oxide (CaO) is one of the prospective heterogeneous catalysts for biodiesel synthesis. Modification of CaO by impregnation on silica (SiO2) can improve the performance of CaO as catalyst. Egg shells and rice husks as biomass waste can be used as raw materials for the preparation of the silica modified CaO catalyst. The present study was directed to synthesize and characterize CaO impregnated SiO2 catalyst from biomass waste and apply it as catalyst in biodiesel synthesis. The catalyst was synthesized by wet impregnation method and characterized by x-ray diffraction, x-ray fluorescence, nitrogen adsorption-desorption, and basicity density. The activity of the catalyst in biodiesel synthesis was assayed at different molar ratios of palm oil to methanol ranging from 1:6, 1:9, 1:12 and 1:15. The biodiesel composition was determined by gas chromatography-mass spectroscopy and the properties of the biodiesel were also characterized. The results showed that the CaO impregnated SiO2 catalyst was successfully synthesized based on confirmation by XRD and XRF. The catalyst has a surface area, average pore diameter, total pore volume, and basicity density of 19.38 m2/g, 3.22 nm, 0.0122 cm3/g, and 3.4 mmol/g, respectively. The catalyst activity assay indicates that the molar ratio of palm oil to methanol of 1:12 is the optimum condition for biodiesel synthesis. At this molar ratio, 81.4% biodiesel yield was achieved, and it met the quality standards according to ASTM D 6751.

This study discussed the effects of doping with silver (Ag) on the optical and structural properties of CdO nanoparticles at different concentrations 0, 1, 2, 3, 4, 5 wt% prepared by the precipitation method. The materials were annealed at 550˚C for 1 h. The structural, topographical, and optical properties were diagnosed by X-ray diffraction analysis, atomic force instrument, and visible and ultraviolet spectrometers. The results show that the average diameter of the grains depends on the percentage of added silver to the material, as the diameter decreased from 88.8 to 59.7 nm, and it was found that the roughness increased from 5.56 to 26.5. When studying the optical properties, it was noted that the energy gap was 2.53ev for the pure sample and decreased to 2.38 When 5% of silver concentration was added to cadmium oxide

A novel metal complexes Cu (II), Co (II), Cd (II), Ru (III) from azo ligand 5-((2-(1H-indol-2-yl) ethyl) diazinyl)-2-aminophenol were synthesized by simple substitution of tryptamine with 2-aminophenol. Structures of all the newly synthesized compounds were characterized by FT IR, UV-Vis, Mass spectroscopyand elemental analysis. In addition measurements of magnetic moments, molar conductance and atomic absorption. Then study their thermal stability by using TGA and DSC curves. The DCS curve was used to calculate the thermodynamic parameters ΔH, ΔS and Δ G. Analytical information showed that all complexes achieve a metal:ligand ratio of [1:1]. In all complex examinations, the Ligand performs as a tridentate ligand, connecting Cu (II), Co (II), Cd (II), and Ru (III) ions through the nitrogen atom of amine , azo groups and the oxygen phenolic group. Cu (II), Co (II), and Cd (II) complexes were characterized as having tetrahedral geometry, while Ru (III) complex was found to have octahedral geometry. The antioxidant activity of the metal complexes was assessed against the DPPH radical (1.1-diphenyl-2-picrylhydrazyl) and compared to that of a common natural antioxidant Gallic acid to observe the produced compounds. The results demonstrated ligands have more antioxidant activity than metal complexes.
