This study is conducted during the period between October 2019 till July 2020 to measure the ratios of some chemical parameters in two species of fish prevalent in Al-Haffar Drainage. The concentrations of fats and proteins measured in three tissues (gills, skin, and muscles) of Tilapia Zilli and Liza Abu fish. The percentages of protein in Liza Abu fish were 14.41, 24.5, 14.47%, while in Tilapia Zilli were as: 14.6, 16.74, and 11.2% for gills, skin, and muscles separately. The levels of protein in tilapia were relatively higher, and the highest levels were recorded in the skin, while in Liza Abu, The highest rate of protein is noticing in the skin and muscles, Fat percentages in Liza. A fish were 1.33, 7.01, 2.09%, while in Tilapia.z f were 2.7, 5.19, and 2.3%, in gills, skin, and muscles, the highest fat ratio is registered in the skin of both species, The lowest levels of fat in Liza. A recorded in the gills, the lowest percentage of Fat in tilapia .z was recorded in muscles.

Time-series prediction is an important statistical topic to help researchers in planning and making the right decisions, so this study deals with modern prediction methods, represented by the Artificial Neural Network models, specifically the multi-layered neural network, and the back propagation algorithm has been relied upon several times for training and less selection. A value for error to obtain the best model for describing the data, as well as classic prediction methods such as Box- Jenkins' models, the model was applied to real data represented by the number of people infected with Coronavirus (Covid-19) in Iraq for the period from 2/24/2020 until 3/5/ 2020 On a daily basis, the results showed that future predictions for the number of people infected with Coronavirus began to decline and then stabilized in the period (30-67). The data were analyzed and the results were extracted depending on the statistical program R.

Abstract : the attractor chaotic from the type Chua’ attractors, was obtained at study one types of electronic circuit chaotic affiliate for family Chua’ circuit, where, the nonlinear part from type memductance, after we succeeded in found the attractor chaotic for circuit, we study many from the methods of synchronization chaos. It was the first method is Pecora and Carroll (PC), but it failed to reach for case complete synchronization, because the ratio of error not equal zero. The same as of result can reach for it, when we applying the method of adaptive-observer, at choose the value of feedback gain c=10. In addition to that, we discussed another method call adaptive feedback synchronization, which Succeed complete synchronization, and the ratio error equal to zero, but exist some noise, which can get rid of it by using the low frequency filter. Also, we suggested new method from the type feedback, which also achieved the complete synchronization, and the noise is disappear clearly, in the method adaptive the complete synchronization achieved after time t=0.05s.

This work starts by reviewing the Pell polynomials; its definition and some basic properties. Afterwards, some new properties of such polynomials are investigated. A novel generalization analytical formula is provided defining explicitly the Pell polynomials derivatives of order n in terms of Pell polynomials themselves. Other explicit formula is concerned with the connection between the Pell polynomials expansion coefficients, this motivates are interest in such polynomials. These formulas are utilized to derive some mainly relationship related with power basis coefficients and Pell polynomials. With the Pell polynomials expansion technique, the powers are expressed in terms of Pell polynomials and an interesting formula is presented with some detail in the proof. An important general formulation for product of two Pell polynomials is also included in this article. All the representations in this work are obtained by explicit computations. Finally, two examples concern boundary value problem and singular initial value problem are included for applications of the proposed interesting properties of Pell polynomials.

In this study, Pell polynomials in two variables, and their properties are investigated. Some formulas for two variables Pell polynomials are derived by matrices. By defining special formula for Pell polynomials in one variable, new important properties of Pell polynomials in two variables can be enabled to derive. A new exact formula expressing the partial derivatives of Pell polynomials explicitly of any degree in terms of Pell polynomials themselves is proved. A novel explicit formula, which constructs the two explicit formulas, which construct the two-dimension Pell polynomials expansion coefficients of a first partial derivative of a differentiable function in terms of their original expansion coefficients, is also included in the present article. The main advantage of the presented formulas is that the new properties of Pell polynomials in two variables greatly simplify the original problems and the result will lead to easy calculation of the coefficients of expansion. A direct spectral method along with the presented two variables Pell polynomials is proposed to solve the partial differential equation. Illustrated examples are included to demonstrate the validity of the technique.

In this paper, we introduce and investigate the notion of projection invariant semisimple modules. Some structural properties of aforementioned class of modules are studied. We obtain indecomposable decompositions of former class of modules under some module theoretical conditions. Moreover, we explore when the finite exchange property implies full exchange property for the class of projection invariant semisimple modules. Finally, we obtain that the endomorphism ring of a projection invariant semisimple modules is a π- Baer ring.
