Objectives The aim of this cross-sectional study was to explore the associations of reallocating time between moderate- to vigorous-intensity physical activity (MVPA), light-intensity physical activity (LPA), sedentary behaviour (SB) and sleep with occurrence, frequency and intensity of low back pain (LBP) among adults using compositional isotempor
There is an increasing need for securing development technology for suitable materials to obtain more productive Dog and Cat and lightweight automobile parts, including hydrogen fuel cell stack enclosures.Due to the poor moldability of Poly-Phenylene Oxide (PPO), which excels in terms of mechanical, thermal, and electrical properties, studies are b
The application of cold-formed steel channel sections for portal frames becomes more popular for industrial and residential purposes.Experimental tests showed that such structures with long-span up to 20 m can be achieved when knee brace joints are included.In this paper, the influence of knee brace configuration on the optimum design of long-span
