In this paper, the multivariate generalized linear mixed model (GLMM) was studied when there are three response variables, distributed as Normal, Bernoulli, and Poisson. And because there is a multiple integration in the likelihood function for the model under study, it is necessary to use mathematical methods to solve this integration, and because it is not possible to obtain the result of this integration by the well-known methods of integration, numerical methods have been used, the Gauss-Hermite Cubature (GHC) algorithm, which is one of the most common numerical integration methods. Then the estimates were obtained by maximizing the resulting likelihood function with respect to the parameters, and thus, estimates were obtained for the parameters. On the practical side, we have used real data representing the effect of potassium as a fixed effect, and referring patients were considered as a random effect on three response variables: calcium, creatinine, and urea as they follow Normal, Bernoulli, and Poisson distributions taken from the records of the Vajin Hospital in Dohuk city. The regression coefficients showed that the effect of potassium is positive on both calcium and urea because the values of the coefficients are positive, while its effect is negative on the creatinine because the value of the coefficient is negative. Based on the results, the researchers recommended several recommendations, including estimating the standard error of the estimates in their light, in order to construct hypotheses for a significance test about regression coefficients.

Markov Weighted Fuzzy Time Series is a forecasting method that applies fuzzy logic to form linguistic variables from existing data. The formation of linguistic variables makes it possible for the forecasting process to be more accurate by considering the uncertainty aspect in decision-making. Its formation is started by grouping the data into a certain number of clusters. The next step is fuzzification, transition matrix formation, and defuzzification for forecasting. In the process of grouping, the existing data will be grouped into several clusters so that it results in the interval length of each cluster. One of the problems of this grouping is the absence of a base standard in the clustering process so it is prone to have a different value in forecasting accuracy. The difference in the number of the class or interval length will result in different accuracy even though the clustering method that is used is the same. In this study, the author proposes the idea of using Particle Swarm Optimization to improve the interval length. The initial interval that is already obtained through the K-means clustering algorithm will be evaluated using the Particle Swarm Optimization method so that it will have a new interval that later will be used in the fuzzification process and forecasting. The accuracy of forecasting can be calculated by using Mean Absolute Percentage Error from Markov Weighted Fuzzy Time Series conventional method and Markov Weighted Fuzzy Time Series method with Particle Swarm Optimization. The result of this study gives an improvement in error value from 8.03% to 5.88%.

Due to the development in various areas of life, the development of the Internet, and the presence of many dataset, and in order to obtain useful information from the rapidly increasing volumes of digital data, there must be theories and computational tools to help humans extract the useful information they need from this data. Large data is collected from many different services and resources. Clustering is one of the most basic and well-known methods of data mining and extraction and obtaining useful information. The technique of recognizing natural groups or clusters within several datasets based on some measure of similarity is known as data clustering. Many researchers have introduced and developed many clustering algorithms based on the different methods of artificial intelligence techniques. Finding the right algorithms greatly helps in organizing information and extracting the correct answer from different database queries. This paper provides an overview of the different clustering methods using artificial intelligence and finding the appropriate clustering algorithm to process different data sets. We highlight the best-performing clustering algorithm that gives effective and correct clustering for each data set.

The electrical continuous glow discharge is in the capillary tubes. It has gained great interest especially in the applications of liquid crystals as well as display plasmas and soft x-ray lasers. In the present work, an electrical discharge system was designed consisting of a capillary tube and two electrodes. The cathode takes on a hollow geometric shape from nickel material to obtain a high current density. The anode electrode is a tungsten material. The inter-electrodes distance was taken as 12 cm. The floating Langmuir double probe was used as a diagnostic Tool to measure the plasma parameters at different ranges of gas pressure for dry air and helium as working gases. The current-voltage characteristics of the double probe were measured at gas pressure 0.2, 0.3, 0.4, 0.5, 0.6, and 0.7 torr. All measurements are conducted at a constant power of 0.6 watt. Electron temperature and ion saturation current were extracted from the I-V characteristics curves. The electron density, Debye length, and plasma frequency were calculated. It was observed that the electron temperature decreases with increasing working gas pressure. The influence of pressure on electron density and ion saturation current gave a clear similarity to the variation in them with pressure in both gases used. Comparisons of the effect of pressure on plasma parameters in working gases were illustrated. The results were in reasonable agreement with previous research.

Smartphones have become widely employed in a range of fields as a result of substantial developments in communication technology, distribution, and the development of numerous types of smart mobile devices. The goal of this research is to secure information sent over mobile phone networks. In this paper, we propose using cryptography to create a more secure application for transmitting confidential information, using encryption to improve security, and depending on the location of the mobile phone user's coordinates, obtained via GPS, to increase security. The XOR process was used between coordinates, the idea was new, the application was implemented, and good results were obtained. The process of converting text into unreadable text is known as ciphering, and in order to achieve it in this paper the Twofish algorithm was used to encrypt confidential information. When sending the coordinates, the RSA algorithm was used to encrypt them as for the Twofish algorithm, the coordinates serve as a key. We conclude that the proposed system used in this study achieved a high level of security.

The n-type Zinc oxide (n-ZnO) nanostructured thin films (TFs) with different thicknesses (211, 325, 433 and 552 nm) were grown onto glass substrates employing the CVD technique at atmospheric pressure. Deposited films were characterized by EDX spectroscopy attached with FE-SEM and XRD techniques to determine the influence of thickness on elemental compositions and crystalline structure of ZnO films, respectively. Also, ZnO TFs were deposited on the p-Si(111) substrates to form different structures of n-ZnO/p-Si heterojunction diodes and then I-V characteristics were studied in the dark. The electrical parameters of the diodes such as rectification ratio (RR), reverse saturation current (Is), ideality factor (), barrier height (b) and series resistance (Rs) were calculated from the I-V measurements. EDX spectra showed that these films were only made from Zn and O elements. XRD patterns presented that the ZnO films possess hexagonal wurtzite structure with preferred orientation along [002] direction. I-V characteristics of the heterojunction diodes revealed rectification behavior and depend on ZnO TFs thickness. Also, electrical parameters of diodes were affected by the prepared film's thickness. It was found that the crystalline structure of the films and electrical properties of diodes were improved with increasing the thickness of ZnO films. It is noted that the best heterojunction diodes were that prepared with thickness (552 nm), where possess lowest value of ideality factor (3.38) and a series resistance (0.84 k) with a highest rectification ratio (1517), compared with other structures. This study offers a simple model for fabricating diodes from semiconductor films.

The aim of this study was to measure osteoporosis in the right heel bone. A total of 123 Iraqi men and women with low back pain (LBP) participated in the study (18 males and 105 females). Quantitative Ultrasound (QUS) was used to assess osteoporosis, speed of sound (SOS), broadband ultrasound attenuation (BUA), and calcaneus bone quality index (BQI). A dual x-ray absorptiometry (DXA) was used to determine tissue thickness, fracture risk factor, and abdominal fat percentage. The results indicate that SOS was 1495.43±18.780 m/sec. Participants had a Z-score of -1.10±1.56. The fracture risk factor for participants was 1.622± 1.90 when DXA measurements were taken. Low back pain measurements revealed that the age group between 51-60 years had the highest prevalence. The correlation between the T-score and the calcaneal SOS is a linear relationship with a P-value of 0.0001. When we examine the relationship between the Z-score and the calcaneal BUA, we see that it is linear and statistically significant (P-value less than 0.0001). The correlations between calcaneal BQI and BMI, as well as between calcaneal BUA and tissue thickness, were found to be statistically insignificant (P-value = 0.8 and 0.8, respectively). The correlation between calcaneal SOS and abdominal fat percent appears to be statistically significant (P-value=0.05) (linear correlation is weak).

Recently, character recognition and deep learning have caught the attention of many researchers. Optical Character Recognition (OCR) usually takes an image of the character as input and generates the identical character as output. The important role that OCR does is to transform printed materials into digital text files. Convolutional Neural Network (CNN) is an influential model that is generous with bright results in optical character recognition (OCR). The state-of-the-art performance which exists in deep neural networks is usually used to handle frequently recognition and classification problems. Many applications are using it, for instance, robotics, traffic monitoring, articles digitization, etc. CNN is designed to adaptively and automatically learn features by using many kinds of layers (convolution layers, pooling layers, and fully connected layers). In this paper we will go through the advantages and recent usage of CNN in OCR and why it’s important to use it in handwritten and printed text recognition and what subjects we can use this technique for. Researchers are progressively using CNN for the machine-printed characters and recognition of handwritten, that is because CNN architectures are suitable for recognition tasks by inputting some images

A study of the influence of the parameters design, such as the refractive index of the core, the cladding and the radius of the core on propagation constant (β) of single-mode optical fiber in optical communication region (1.2-1.6) m have been investigated. Material, waveguide, and profile dispersions are analyzed and investigated. Three models of optical fibers with different relative refractive indices () (0.004, 0.007, 0.01) at a wavelength equal 1.55 m, and three models of core radius (3,4,5) m is taken in the count. Numerical simulations and modeling are arranged depending on weakly guiding approximation for solving homogeneous wave equation derived from Maxwell’s equations. Our modeling solved by the aid of MATLAB software. Material and profile dispersion have no significant change for various relative refractive index, while waveguide dispersion is affected by the change of relative refractive index. the waveguide dispersion increased by increasing core diameter and the profile dispersion decreased as the core diameter increased. There is no effect on martial dispersion by increasing the core diameter.

The uranium concentration and radioactivity of radon gas were measured in Al-Kasik refinery and Ain Zala field using the CR-39 detector. Soil and water samples associated with the production stages of oil, Sludge and crude oil were collected. The levels of uranium concentration in soil ranged from 0.703 to 1.480 ppm, in water samples from 0.681 to 0.716 ppm, in Sludge samples from 0.849 to 1.014 ppm, and in crude oil from 0.785 to 0.933 ppm. As for the radioactivity of radon gas, when comparing the radon rate in the samples we obtained with the global values, it was found that it falls within the internationally permissible limit, where the radon rate in the soil was 12.81 Bq/kg and when compared with the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) which has a value of 32 Bq/kg, and in the produced water it was 8.66 Bq/kg compared to (UNSCEAR)which has a value of 50 Bq/kg. In Sludge samples 11.81 Bq/kg and when compared with the International Atomic Energy Agency (IAEA) whose value is(8-5×〖10〗^5) Bq/kg, and in crude oil samples 10.56 Bq/kg and when compared with the International Federation of Oil and Gas Producer (IOGP) whose value is (800-4×〖10〗^5) Bq/kg. As for the alpha ray hazard index, the results showed that it is within the permissible limits internationally, where the results were less than 1 and therefore does not pose a threat to the health of workers and environment.

Bone marrow depression is the mo:.it serious dose limiting toxicity of hydroxy urea . Natural apple cider vinegar in supposed to have both chemo-proteotive and myelo -stimulatory effects .
In this study , hydroxy urea at a dose of 80mg/kg/day orally produced significant depression of red blood cell, adecrease in white
blood cells and platelets in mice . 20mg/kg/day of apple cider vinegar seven days after hydroxy urea was administered produced no improvement in red blood cells and white blood cells and platelets counts.
The administration of apple cider vinegar with hydroxy urea produced significant (P<0.05) increase in red blood cells and white blood cells while platelets not recovered to normal .
The effect of hydroxy urea in mice on protein was observed as depressant effect significantly (P<0,05) on total protein adecrease in albumin and globulin .
The administration of apple cider vinegar seven days after hydroxy urea produced no significant effect on globulin and albumin , yet the total protein increased but not significantly .
The administration of apple cider vinegar at the same time with hydroxy urea significantly increase total protein and globulin , while no change on albumin level .
The results in this study indicate that apple cider vinegar has a protective effect on bone marrow from depressive effect of cyto toxic drug hydroxyurea .

ABSTRACT
This study is aimed to make a comparison between three artificial neural networks, these networks differ from each other in architecture and the method of adaptive the weights. In this research four ANN are used to recognized English number, these ANN are Adaline, Backpropagation, Hopfield, and Kohen ANN. By doing the comparison, we found that, the ability of a network differentiation does not depend on the complexity of the network architecture, the training algorithm or the number of layers, but it depends on the learning rule and increase in the number of the patterns that are used to train the network.

ABSTRACT

The biological study was conducted at the University of Mosul, College of Education, Department of Biology. To aims at identifying effects of environmental pollution in the seven sites at Nineveh (Al-Rahmanyah,Al-Rashidiyah, Yarmejah, Hamam Al-Alil, Al-Nimrud, Al-Qayarah and Sinjar) in concentrations of heavy accumulated metals,(Pb,Cd,Ni,Co) in the parts that are eaten from leguminosae plants.
The study results showed that pods of leguminosae plants in different sites contained heavy metals with different concentrations within the normal levels of toxicity: cobalt (0.53-1.36), nickel(0.1-5), cadmium (5-30), lead (30-300)ppm. the concentration of cadmium was over than (0.1)ppm., which applied by (WHO).

Summary
This research shows that the white seeds agreement with the effect of magnetic flux density and magnetic water in most characteristics studies allowed by vegetative growth such as (The grew, plant height, number of leaf, leaf area's, number of roots, dry weight and wet weight).
On the other hand, they shown that when treated by magnetic water and the normal soil it get the best in most characteristics studies from the treated by normal water and normal (such that 46% to relative grown, 8.048 cm height, 8.048 average of leaf number, 4.08 cm2 area's leaf, the number of roots 5.78 / any plants and the wet weight is 1.457 gm). Also, they shown that when treated by magnetic soil and normal water it get the best in most characteristics studies from the treated by water and normal (such that 64% to relative grown, 8.048 average of leaf number, 4.91cm2 area's leaf, the number of roots 7.92 / any plants and the wet weight is 1.75 gm) unless the characteristics about the height which defeated the treated by magnetic soil and magnetic water at the treated by normal water magnetic soil.
