Nanoparticle (NP)-based polymer nanocomposites have received significant attention in recent years, particularly those based on carboxymethyl cellulose (CMC). This study aims to synthesize and characterize of nanocomposites derived from grafted CMC. Because of the presence of polar functional groups, such as carboxyl and hydroxyl groups, in CMC, which contribute significantly to its strong adsorption capacity in metal structures, some research has indicated that this CMC is effective as a corrosion inhibitor, especially after being coated with NPs, as it protects metal surfaces from corrosion and helps them create a protective layer. In this study, nanocomposites derived from grafted CMC were synthesized. Initial CMC underwent a reaction

The algorithms has a great role to find zeroes of metric projection point , fixed point and common fixed point in Hilbert space .It is well known that the metric projection mapping plays important role in Fixed point theory , Differential Equations, Optimization theory and Variational Inequality problem. The success, effectiveness, speed and superiority of iterative methods over other approximate methods depend on two important factors: The first is the number of iterations, and the second is time. In this paper, we introduce new iterative, it has been generalized to a number of algorithms, such as the algorithm used in27, which is considered a generalization of the Ishikawa's iteration algorithm.

A cantilever beam is made from composite material which is consist of (matrix: polyester) and (particles: Silicon-Carbide) with different volume fraction of particles. A force is applied at the free end of beam with different values. The experimental maximum deflection of beam which occurs at the point of the applied load is recorded. The deflection and slope of beam are analyzed by using FEM modeling. MATLAB paltform is built to assemble the equations, vector and matrix of FEM and solving the unknown variables (deflection and slope) at each node. Also ANSYS platform is used to modeling beam in finite element and solve the problem. The numerical methods are used to compare the results with the theoretical and experimental data. A good ag

Conclusion:
The arm plays a crucial role in the freestyle swimming stroke, especially during the propulsion phase, contributing significantly to efficient movement and limb coordination. However, many learners, particularly female students at the College of Physical Education and Sport Science at Baghdad University, face difficulties mastering this skill. Traditional training methods lack immediate feedback on arm force balance and quality, limiting opportunities for simultaneous motor learning and technical improvement. To address this, a new swimming aid was developed to quantitatively measure palm pressure during swimming movements. The device includes sensors on both hands, a data processing unit, and a real-time force coo
