Concrete is still widely used for structural purposes as a building material. Testing the compressive strength of concrete is the most essential aspect of determining the quality of the concrete. This research was conducted to ascertain the correlation value of the compressive strength test results of concrete conducted in the laboratory with a compression strength machine (destructive test), a hammer test, and an ultrasonic pulse velocity (non-destructive test). Cylindrical specimens with 15 MPa, 20 MPa, and 25 MPa concrete strength were subjected to testing. Based on the results of the upv test and compression test, the regression equation for the relationship between wave velocity and concrete compressive strength is determined.......

Paving blocks, which consist of concrete bricks blended with sand and cement, are frequently employed in ground surface hardening construction due to their favorable characteristics. These include being precast materials that possess a comparatively sizable form, the capability to absorb water, comparatively affordable prices, and ease of manipulation. Paving blocks consist of supplementary components, specifically mineral admixtures, in addition to the primary components of water, aggregate, and cement. The inclusion of these substances serves to enhance the overall quality of paving blocks. Included among the mineral admixtures utilized in this investigation are gypsum, quartz grit, and limestone.......

Thyroid nodules, which are characterized by unusual thyroid cell proliferation, may be a sign of an iodine intake that is too high, thyroid degeneration, inflammation, and other disorders. Although thyroid nodules are mostly benign, the chance that they are cancerous increases considerably each year. Many experiments have been conducted to identify thyroid nodules using deep-learning-based image recognition analysis, reducing the labour of medical professionals and avoiding unnecessary fine needle aspiration and surgical removal. The data was imported directly from the hospitals in Algeria, and volunteer doctors labelled it........

In this paper, we investigated the magnetohydrodynamics (MHD) boundary layer flow with heat and mass transfer over a moving vertical plate in the presence of magnetic field, thermal radiation, heat absortion/injection, chemical reaction and a convective heat exchange at the surface with the surrounding. Partial differential equation describing the problem is formulated and the similarity variable is used to transform the system of partial differential equations, describing the problem under consideration, into a boundary value problem of coupled ordinary differential equations, and an efficient numerical technique with help of Maple is implemented to solve the reduced system. The results are presented graphically.......
