The Modified Newton method (MNM) is applied to obtain the approximate solution to the system of nonlinear Volterra type integral equation with the trigonometric kernel function. Modified Newton method (MNM) is used to linearized the system then solved by the Nystrom type Gauss-Legendre quadrature formula (QF). A new majorant function is stated which leads to the increment of convergence interval. The existence and uniqueness of approximate solution are proved. Sufficient condition for the approximate solution is established and their validity is illustrated with example.

In this paper, we consider the local fractional Adomian decomposition method for solving the second kind Volterra integro-differential equations within local fractional integral operators. This application maintains the efficiency and accuracy of the Adomian analytic method for solving local fractional integral equations. Illustrative examples are given to show the accuracy and reliability of the results.

Optical modulator is an important component in optical system. It is a device, which changes the angle between the vision line to the target and coordinate to electrical signal. The optical modulator modulates the optical signal by a frequency depending on the shape and number of sectors. The optical modulator takes various circular shapes due to the need for it. Through this study we have designed the fractal optical modulator consisting of eighteen sector , by building a computer program (SAM1) using visual basic language. In this paper assume that nine sectors one opaque and the other nine sectors are transmitted for the light. One may consider these nine sectors also as opaque for the other regions of electro-magnetic wave spectrum. For the importance of the modulation transfer function (MTF) in testing and evaluating optical systems, it becomes the dependent measurement to know the optical systems efficiency. It has been studied for optical systems with circular aperture, where that function could evaluated the image efficiency for point object in image plane at different magnitude of transmittance. In this research, the fractal optical modulator has been designed of semiconductor material by using the fractal function. Then evaluating the values of MTF at different values of refractive index and transmittance. The best modulation of Calcium Fluoride CaF2 material optical modulator was when transmittance T = 89%. Where the value of Modulation Transfer Function (MTF) is maximum at refractive index η λ=0.400µm (CaF2)= 1.4419. The worst case of modulation was at transmittance T = 36%. Where the value MTF is minimum at refractive index η λ=0.161µm (CaF2)= 1.5490.

The present study aims to find out some blood parameters, indicators of liver function and lipoproteins level in athletes smokers. Research sample included 81 person divided into four groups: Smoker Sportsmen SS (15) , Smoker ordinary SO (25) , No Smoker Sportsmen NSS (20) , No Smoker Ordinary NSO (21). The blood samples were taken for checking RBC and WBC, PCV, Hb, liver enzymes (ALT, AST, ALP),blood proteins (total protein, albumin), lipoproteins (Total cholesterol, Triglycerides TG, High and Low density lipoprotein HDL &LDL). The statistical analysis showed that RBCs, WBCs count , Hb level , PCV and ALP enzyme have elevated levels in smokers group (SS, SO), while Total Protein and albumin were decreased, but the enzyme AST and ALT were rised in SS group compared to the remaining groups (P˂0.05). TC level was high for the (SS, SO) groups, while TG and LDL level was more increased in group SO. The level of HDL was decreased in smokers group (SS, SO) (P˂0.05). We conclude from the foregoing that smoking possessed harmful effects on the human body and sports may reduce the harmful effect of smoking, as that of the resolve to cut smoking advised them(smokers) to perform moderate training to remove the accumulated effect of smoking on the various organs of their body.

Life without water is wasting because water is very important to life activities, and it is the main tributary for agriculture and industry. Water system of filtering water includes the main stages such as productions, transmission, and distribution, therefore; large amount of water will loss through the processes of this step of water production before it received by the consumers. In this case, the amount of produced water is less than the amount of consumed water in filtering water. Thus, for the purpose of understanding and attempt to diagnose this problem, flow scheme was established to predict the water consumption by using modeling in a time series depending upon Box- Jenkins technique at Thi-Qar province during the period of 2016- 2020. The results of this search showed that the water consumption will be slightly above the usual for the years 2016 and 2017,and the increasing in water C0nsumption will noticeably and exponentially until 2020.
