Phosphoric acid is used in various products like food, sweets, beers, and soft drinks. Higher phosphoric acid concentration in urine accelerates the formation of carbonate apatite and hydroxyapatite, which are key components of infection urinary stones, a negative effect. However, the amount of these solid phases is smaller, which is beneficial.

Behaviour Based Safety (BBS) - Advantages and Criticism
Behaviour-Based Safety (BBS) is a popular approach to enhancing occupational safety, with many researchers reporting successes of implementing BBS programs. There are, however, studies that see this approach as illusory, bringing more harm than good. The

The Effect of Aluminium on Graphitization of Cast Iron Treated with Cerium Mixture
The work determined the influence of aluminium in the amount from about 0.6% to about 8% on graphitization of cast iron with relatively high silicon content (3.4%-3.9%) and low manganese content (about 0.1%).

Poststrengthening Remote Monitoring in Practice: A Case Study of RC Structure Renovation
Reinforced concrete (RC) structures are widespread globally, requiring systematic monitoring and proactive maintenance due to ageing, evolving demands and environmental exposure. Prolonging the service life of existing RC structures to meet modern requirements promotes sustainability by reducing waste, conserving resources and minimising environmental ...

The authors’ research study employs full‐potential (linearised) augmented plane wave (FP‐(L)APW) calculations alongside experimental techniques to elucidate the band structures, dielectric functions, and other significant optical parameters of w‐ZnO, w‐ZnS, and w‐ZnSe. The band gap values derived theoretically, 2.72 eV for w‐ZnO, 3.87 eV for w‐ZnS, and
