Macro-roughness elements such as boulders and bedrock outcrops, collectively referred to large bed (LBEs), are key features influencing hydrodynamics morphodynamics in mountain rivers. Where LBEs abundant account for a substantial portion of total flow resistance, existing geomorphic theory, previous physical experiments, limited field observations support the theory that LBE configurations adj...

Sediment compositions and trace element (Cu, Pb, Zn, Cr, Fe, Mn, As, Hg) concentrations were analyzed to assess the sediment quality factors affecting elements’ concentration in Ha Tinh province’s coastal sediments. Results revealed that of elements sediments was generally lower than other areas Vietnam. The significantly positive correlation fine composition with Cu, Fe indicated silt clay cou...

Abstract Placelessness and the loss of a place’s identity, along travel corridors, can generate few problems like fatigue in driving, difficulties wayfinding limit people from exploring new places architectural buildings. The sense familiarity similarity views roadways are often overlooked, which result development monotonous mundane highways, leading to place identity. There is an imperative n...

More than 100 years ago, Lionel Robert Wilberforce did investigations On the Vibrations of a Loaded Spiral Spring [1]. The spring was clamped at its upper side and on other side, perpendicular to axis, steel cylinder attached. Four screws with adjustable nuts were symmetrically attached around in order change moment inertia (Fig. 1). In this paper pendulum is modeled by rigid body constrained s...
