Data mining techniques are the Amounts of actual data are used to analyze these data to predict whole some data to support a decision-making in a problem-solving. A data mining is very useful to analyze any disease characteristics to support the decision process and specify what the disease is and what Details IS. In the proposed present papers, using the real algorithms of data mining techniques to support different healthcare fields and adopted a correct decision about the diagnosis of emphysema disease and specify the risk factors for this disease to support decision process. In this research, a data-mining model of EmD prediction using a hybrid model Radial Basis Function - Neural Network (RBF-NN) and Genetic Algorithms (GA) has been presented. From the results, it has been seen that a hybrid model predicts EmD with nearly 95% accuracy. Furthermore, the examined samples of individuals share the same risk factors a symptom. Data mining depends on these symptoms and factors to diagnosis obstructive emphysema disease.

The objective of this work is primary focus on iron-polyphenol complex were synthesized using the extracts obtained from black tea leaves interaction in aqueous solution at different concentrations of iron solutions and the resulting chelators iron-polyphenol complexes was characterized, using infra-red spectroscopy (IR) and ultraviolet-visible spectroscopy (UV). Determination of the iron concentration in blood serum was carried out on nine youth health volunteer's female student from Iraqi population (Diyala University-College of science) who are drinking tea particularly tannin rich dally with the meals, and then re-measuring their iron levels after stop to take it for five days, sensitive atomic absorption spectroscopy has been used for iron determination in serum samples. The results show that the reaction between iron ions and polyphenol can form complex. Based on data from atomic absorption during tea consumption and after stop drinking found that no significant inhibition in the iron level in younger students was noted, however, the iron values that measured in the serum samples by atomic absorption method are agreement with the natural value of iron level in the body.

Distinguishing car plate numbers is an important topic of researchers' concern, which assures the process required to be high speed and acceptable accuracy, with the need to access the database and verify it if there was a problem and give a warning if it is necessary. A method is proposed in this paper to distinguish the plate of Iraqi vehicles (new forms), which will prevail in the end, depends on the pre-processing of the image and apply some filters such as (median filter) as well as improving the image before starting the proposed method, which relies on a normalization in the horizontal and vertical direction process and then segment the image into regions. Information is extracted from each region, such as the area that defines the type of vehicle if it is a governmental, private, taxi, or others. The region that characterizes the city as well as Arabic and English, numbers region is segmented and then transform with single value decomposition (SVD) on the image and get features that will send to the database for identification. The proposed method has given a percentage of accuracy of about 90.4 % in the process of discrimination with significant time complexity on average using K-Nearest Neighbor K-NN classifier. It possible to implement the proposed method with application of emergency alarm, to give a warning alert.

Paracaryum shepardii Post & Beauv. is a new record to Boraginaceae in Iraq, found in Hasarost mountain (north-east of Erbil) within Rowanduz district (MRO). The collected plant specimens differ from the three-other species that already present in Iraq, where P. shepardii differs from P. rugulosum (DC.) Boiss., P. sintenisii Hausskn. ex Bornm. and P. strictum (C. Koch.) Boiss in that the wings of the nutlets are flat and not covering the disc, while in the other three species the wings are strongly incurved and partly covering the discs, as well as some other characters. Identification and morphological study was done, these clarified by photographs. In addition, some characters of the pollen grains such as shapes, colors, sizes, sculptures and numbers, together with stomatal complex characters of the leaf have been studied.

The Gradient energy coefficient () in polymers and oligomers (a few segments) play an
important role in polymer blending, wetting, coating, adhesion process, foaming and a
comprehensive role in the description as well as understanding of many processes especially in
innovation of new polymer with classification of materials. As a result, the main reason in this
study appear which has how the gradient energy coefficient changes from bulk to surface, has
been establishing the new equation that helped us to extract the correlation between gradient
energy coefficient and different parameters. The gradient energy coefficient has been related
with hole fractions, temperature and density. The relationships between the above-mentioned
parameters are then drawn according to our model. Both Simha-Somcynsky (SS) and Cahn-
Hilliard (CH) models are employed together to calculate the thermodynamic properties of
cyclohexane, namely, the hole fraction in temperature range at 313-473 K various presures up
to 150 Mpa. Our values for the average and maximum percentage deviation of the specific
volume of cyclohexane are calculated as 0.0196% and 0.0678% respectively

This work is concerned with studying the adsorption of some azo dyes better on commercial activated carbon. The dyes were synthesized by considering the resorcinol as constant part in their structure which is reacted with a number of para substituted aniline via dizonium ions and used as adsorbate for achieving this study. These dyes were identified by a number of physical tests and the available spectroscopic methods. Three models of adsorption isotherms namely, Freundlich, Langmuir , and Tempken are applied to fit the experimented data of adsorption at equilibrium in the range of concentration (1*10-4- 5*10-4)M at various temperatures (292-328)K, and using (1gm/L) of the Adsorbent (Activated Carbon). The results showed that, the Freundlich isotherm is better fitted to the experimental data of the studied systems, although Langmuir isotherm exhibited good fit. This work included performing thermodynamic, depending on calculating the equilibrium constants by different methods, which represented by Freundlich constant Kf, Langmuir constant (KL) and finally is described by Tempkin constant (TK). The results showed good consistency among the four sets of functions in terms of their values and physical meaning. This consistency gave good indication for the accuracy of such kind of calculation.

The present study was conducted to investigate the changes in tissues in patients with scabies. The biopsies from patients with scabies and from patients infected with cutaneous leishmaniasis (positive control) were collected from patients attended the Dermatology Unit at Baquba Teaching Hospital / Advisory Clinic during the period from March to May 2016. The ages of the studied groups ranged between 20-54 years. The results showed that there were histological changes in patients with scabies, including thickness of epidermis and filtration of inflammatory cells of dermis and hyperkeratasis in some chronic cases. In addition, some chronic cases showed edema, degenration and necrosis of some epidermis cells. In contrast, the results of the present study showed that the histological changes associated with leishmaniasis included hyperkeratenosis, epidermis and spongiosis, as well as the formation of reteridges. In addition, there was infiltration of inflammatory cells in dermis as well as the presence of necrosis and degeneration in some infected skin cells.

The synthesis and study mesomorphic properties of a new series of 2,4-bis(4-n-heptyloxybenzoyloxy)-benzylidene-4-n-alkoxy aniline (DC7A1-10) Have been reported. The structures of the prepared compounds were confirmed by FT-IR, 1H-NMR and elemental analysis (CHN). The mesomorphic properties were studied by differential scanning calorimetry (DSC) and polarizing optical microscopy (POM) measurements. All compounds of the series exhibited nematic (N) phases but the smectic phases are appear in (DC7A3-A10). The first two series (DC7A1, DC7A2) display only a nematic phases whereas the highest homologues (DC7A3-A10) exhibit enanthiotropic dimorphism Nematic (N) and smectic (S) phases (the DC7A6 is only compound exhibit Sc and SA phases). The liquid crystalline behavior has been analyzed in terms of structural property relationship. The mesomorphic properties and thermal stabilities of the present series (DC7A1-10) were compared with those structurally related homologous series.
