The Small Punch technique is a miniature test used mostly for irradiated materials or when the test material is scarcely available. The main aim of small specimen mechanics is to figure out the mechanical behavior with a great reduction or small volume of material. This document emphasizes the development of correlations between mechanical characteristics determined from small punch tests and uniaxial tensile tests. Recommended techniques for specimen design, specimen preparation, experimental design, experimental implementation, and data analysis are used according to ASTM SPT 888. The test i

Abstract: Honey has unique components, a characteristic that makes it a valuable food for consumers. It is known that UV radiation and heating impact the quality of honey's bioactive compounds, including total phenolic, total flavonoid, and brown pigment contents. The absorbance of brown pigment at a wavelength of 420 nm, total phenolic at a wavelength of 733 nm, and total flavonoid at a wavelength of 430 nm was measured using a UV-Vis spectrophotometer. The method used in the total phenolic test was the Folin-Ciocalteu method with gallic acid standard (mgGAE/g sample). In contrast, for flavon

This study investigated the effects of additional PVA on the physicochemical properties of the chitosan-glutaraldehyde/gelatin bioplastic composite. The best results of the bioplastic film were obtained at a concentration of 3% PVA, with a tensile strength value of 3.3 MPa, flexibility reached 54%, a thickness value of 0.24 mm, percentage of inhibition against E. coli and S. aureus was 21.8% and 8.8% respectively. The FTIR spectrum results showed no change in the wavenumber of the chitosan and gelatin chitosan spectrum with OH, CO, and NH functional groups. The spectrum indicates that only phy

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors with high mortality worldwide, which is characterized by aggressive growth and metastasis. However, the relationship between TOP2A and CDC6 and HCC remains unclear. GSE121248 and GSE101728 profiles for liver cancer were downloaded from the gene expression omnibus database generated using GPL21047and GPL570. Differentially expressed genes (DEGs) were screened and weighted gene co-expression network analysis was performed. The construction and analysis of protein–protein interaction network, functional enrichment analysis,

Cannon barrel life can be maximized by fully understanding the correlation between temperature and hoop stress and their relation to crack growth. Use of elevated temperature fatigue to predict failure of a gun barrel based on the number and type of rounds along with temperature data will both maximize the usable life of a cannon barrel and maintain a safe operating environment the men and women using these cannons. This analysis will help increase the usable life of large caliber cannon barrels; round data that is collected throughout the life of a cannon barrel will be used to determine the
