This work analysed bed lamella dimensional characteristics for beds of bariatric users. Dimensions the Slovak population were defined in years 2020 to 2022 and used design length thickness lamellae. The lamellae made spruce beech wood (grade C24 D50) was determined from weight while meeting requirements EN 1995. bending deflection calculated by a linear FEM model that verified with experimental...

A crucial permutation is a that avoids given set of prohibitions, but any its extensions, in an allowable way, results prohibition being introduced. 
 In this paper, we introduce five natural types permutations with respect to monotone patterns, notably quadracrucial are linked most closely Erdős-Szekeres extremal permutations. The way define right-crucial and bicrucial consistent the defi...

Shortfin scad ( Decapterus macrosoma ) is an essential economic fish resource that spreads over tropical and subtropical oceans mostly caught in Bali Strait. High market demand for this leads to increase fishing efforts. In contrast, uncontrolled efforts will threaten its sustainability potential. This research was conducted based on catches during February – March 2020 total samples of 1,115 c...
