This study shows how the structural and dielectric properties of (SnO₂)_1-x(Mn₂O₃)_x, (where x=0.00, 0.03, 0.05,0.07, and 0.09) prepared using the solid state reaction technique, are affected by the doping of semiconducting metal oxide Mn₂O₃. Structural analysis of the composites was carried out using information from the composite samples obtained from X-ray diffraction (XRD). The diffraction peak shifting in XRD patterns indicated that Mn ions were successfully incorporated into the SnO₂ crystal lattice. Mn ions were successfully doped in the Tin oxide matrix lattice with the subsequent increase of doping levels. The average crystal size evaluated usi

     This study employed a simple hydrolysis method to synthesize two novel nanocomposites: ZnO/g-C₃N₄ (ZCN) and TiO₂/g-C₃N₄ (TCN). Characterization results confirmed the successful integration of ZnO and TiO₂ nanoparticles onto g-C₃N₄ nanosheets, resulting in enhanced optical absorption in the visible light region. Both synthesized ZCN and TCN composites exhibited higher photocatalytic degradation efficiency of the antibiotic doxycycline under visible light irradiation compared to their individual component materials. This enhancement is attributed to the formation of heterojunction between TiO₂ or ZnO and porous g-C₃N₄

In this research, we analyzed the effect of the magnetic field on the axial velocity function, as well as the stream function of non-Newtonian Wallers-B fluid in the inner duct and walls of curved peristaltic channels. This model was examined assuming along wave length and a low Reynolds number relative to a small Brinkman number (Br) using the modern and effective technique of the Mathematica program, the exact solutions of the governing partial differential  equations were found. After they were converted to ordinary differential equations. We verified the numerical results through the graphs of all the physical parameters and used the regular perturbation method to reach the numerical solutions for both the axial velocity and flow fu

This research aimed to evaluate the radon concentration for 11 different samples of consuming foodstuff collected from the markets. Alpha- CR-39 track detectors were used to analyze the radium concentration and radon exhalation rate. Al-Sayed coffee powder had the highest radon concentration of 99.7 Bq/m3 , while Al-Warda sugar had the lowest concentration of 56.5 Bq/m3 . The surface exhalation rate for the powdered milk samples varied from 2.3Bq/ m2 .h in Al-Marai sample to 3.5 Bq/m2.h in sample Anchor. While the coffee powder samples ranged from 2.4 Bq/ m2 .h in sample Al-Rifai to 3.7 Bq/m2 .h in sample Al-Sayed. The sugar samples varied from 2.11 Bq/ m2 .h in sample Al-Warda to 2.3 Bq/m2 .h in sample Al-Usra. The lifetime  cancer ris

    In this paper, we developed an  epidemic model for COVID-19 by using compartmental analysis. In our model, we divided susceptible individuals into two separate groups: one for high-risk individuals and another for those at low risk. In this work, we have proved theorems about the non-negativity and boundedness of the solutions. Afterward, we obtained a disease-free equilibrium point and an endemic equilibrium point. We calculated the basic reproduction number using the next-generation matrix method and then we expressed theorems about the local and global stability of equilibria, finally, we have gone to the sensitivity analysis and numerical analysis.

This paper presents two subclasses of analytic and bi-univalent functions associated with the Ruscheweyh derivative operator to investigate the bounds for  and where  and  are the initial Tayler-Maclaurin coefficients. The current results would generalize and improve some corresponding recent works. Additionally, in certain cases, our estimates correct some of the existing coefficient bounds.

This paper's primary goal is to present the connection between coding theory and the projective space PG(5,q) of order q, where q={2,3,4,5,7,8,9,11} It was determined whether or not the [n,k,d]-code is perfect. Where n is the length of the code, k is the code dimension, and d is the minimum distance, were calculated with error correction e according to the incidence matrix. We have found that the [n,k,d]-code in PG(5,q), q= {2,3,4,5,7,8,9,11}, is perfect if e = 1.

A field experiment was conducted in the fields of the University of Baghdad to determine the effect of clover residues mixed with the soil in which the barley crop (Arviat variety) was planted. Residues of two varieties of clover (Red clover and Egyptian clover) were added at a rate of 3 and 6grams of plant residues. Two control treatments were also implemented with 3 and 6 grams of barley straw for comparison purposes. The results showed that the clover residues significantly reduced the germination and growth of the barley crop. However, this inhibition increased significantly when plant residues were added to the Egyptian clover variety at concentrations of 3 and 6grams, achieving inhibition in the germination of barley seeds. It achi

     In this paper, two different chaotic dynamic systems are coupled using a semiconductor laser to produce a new chaotic system. These two chaotic systems are Rossler and Chua systems. X-dynamic of Rossler system was coupled optically using optical fiber as a carrier of signal with x, y, and z-dynamics of Chua system. The results were analyzed and the behavior of Chua system was found to be changing in time series which, in turn, changed the attractor. The Chua attractor was converted from double scroll to single scroll. The results obtained from connecting two different systems in chaotic behavior showed a remarkable increase in the bandwidth of Chua system. This increase in bandwidth opens up a wide field for many

Four hundred and seventy eight gravity base stations in Iraq were used to obtain a new local theoretical gravity equation. The obtained equation was used to construct a Bouguer anomaly map of Iraq depending on the available gravity base stations. This map was compared with the Bouguer map constructed for the same stations using the international formula (1930). Good similarity in shapes and locations of the anomaly were observed, while the   gravity anomaly values in the new map were increased by about 30 mGal. The eastern zero gravity contour line of the new obtained gravity map coincides with the western  boundary of the tectonic Mesopotamian zone, while the main negative  gravity values coincide with the Mesopotami

The aim of this paper is to approximate multidimensional functions feC(R) by developing a new type of Feedforward neural networks (FFNNs) which we called it Greedy ridge function neural networks (GRGFNNs). Also, we introduce a modification to the greedy algorithm which is used to train the greedy ridge function neural networks. An error bound are introduced in Sobolev space. Finally, a comparison was made between the three algorithms (modified greedy algorithm, Backpropagation algorithm and the result in (11) 

Given a binary matrix, finding the maximum set of columns such that the resulting submatrix has the Consecutive Ones Property (C1P) is called the Consecutive Ones Submatrix (C1S) problem. There are solution approaches for it, but there is also a room for improvement. Moreover, most of the studies of the problem use exact solution methods. We propose an evolutionary approach to solve the problem. We also suggest a related problem to C1S, which is the Consecutive Blocks Minimization (CBM). The algorithm is then performed on real-world and randomly generated matrices of the set covering type.

     Improving the performance of visual computing systems is achieved by removing unwanted reflections from a picture captured in front of a glass. Reflection and transmission layers are superimposed in a linear form at the reflected photographs. Decomposing an image into these layers is often a difficult task. Plentiful classical separation methods are available in the literature which either works on a single image or requires multiple images. The major step in reflection removal is the detection of reflection and background edges. Separation of the background and reflection layers is depended on edge categorization results. In this paper a wavelet transform is used as a prior estimation of background edges to sepa

Etherification of n-hexanol, n-heptanol and n-octanol with propargyl bromide in the presence of sodium hydroxide in DMF afforded the terminal alkynes (2) a, b and c. Phenacyl bromide, p-bromophenacyl bromide and p-phenylphenacyl bromide were converted to corresponding azides (4) a, b and c respectively by traditional SN2 reaction of the mentioned bromides and sodium azide in DMF. The cycloaddition of the propargyl ethers (2) with the prepared organic azides (4) using click conditions gave the target 1,4-disubstituted 1,2,3- triazoles (5)-(7) in good yields. All the synthesized triazoles were characterized by FT-IR while the compounds (5) a,b and c were characterized by 1H NMR and 13C NMR in addition to FT-IR technique.

Data security is a significant requirement in our time. As a result of the rapid development of unsecured computer networks, the personal data should be protected from unauthorized persons and as a result of exposure AES algorithm is subjected to theoretical attacks such as linear attacks, differential attacks, and practical attacks such as brute force attack these types of attacks are mainly directed at the S-BOX and since the S-BOX table in the algorithm is static and no dynamic so this is a major weakness for the S-BOX table, the algorithm should be improved to be impervious to future dialects that attempt to analyse and break the algorithm  in order to remove these weakness points, Will be generated dynamic substitution box (S-B

     Storing and transferring the images data are raised in recent years due to requisiteness of transmission bandwidth for considerable storage capacity. Data compression method is proposed and applied in an attempt to convert data files into smaller files. The proposed and applied method is based on the Wavelet Difference Reduction (WDR) as considered the most efficient image coding method in recent years. Compression are done for three different Wavelet based Image techniques using WDR process. These techniques are implemented with different types of wavelet codecs. These are Daub2+2,2 Integer Wavelet transform, Daub5/3 integer to integer wavelet transform, and Daub9/7 Wavelet transform with level four. The used mu
