Effects of noise exposure on occupational stress among palm oil mill workers in Malaysia
Published 2015“…The environmental noise resulted from operating machineries usually exceeded the NIOSH (1999) recommended exposure limit of 85 dB (A) and as one of the major environmental stressors in palm oil mills is always considered as a key factor in creation of a series of complaints and develop occupational stress as a chronic disorder among palm oil mill workers. …”

Non-invertible Condensation, Duality, and Triality Defects in 3+1 Dimensions
Published 2023“…We further prove that some of these non-invertible symmetries are intrinsically incompatible with a trivially gapped phase, leading to nontrivial constraints on renormalization group flows. Duality and triality defects are realized in many familiar gauge theories, including free Maxwell theory, non-abelian gauge theories with orthogonal gauge groups, $${{{\mathcal {N}}}}=1,$$ N = 1 , and $${{{\mathcal {N}}}}=4$$ N = 4 super Yang-Mills theories.…”

Surface functionalization of oil palm empty fruit bunch (OPEFB)-derived cellulose as a carboxyl platform for metal cations and dyes removal from aquatic media
Published 2024“…The abundant oil palm empty fruit bunch (OPEFB) as by-product of palm oil milling processes exhibits a potential as an alternative cellulose feedstock for bio-adsorbent. …”
