Abstract:

Thailand as a prospering country hoped to retain the quality of education for its students. However, despite efforts to accomplish this intention, a number of students are still struggling to retain their engagement in school due to their declining academic buoyancy. With this reality, efforts are undertaken inside the classroom to address this pressing concern. While classroom-based interventions are known to deliver desirable results, a scarcity in psychoeducation programs remains unexplored; hence, the initiation of this quasi-experimental nonequivalent pretest and posttest control group st

This modeling evaluation shows that the model simulates precipitation well but overpredicts clouds, especially in the upper troposphere.

Abstract The article presents a design of a floating platform for offshore wind turbines.

This solution makes it possible to influence the position of the centre of buoyancy and the centre of mass of the structure. Compared to the classic Spar platform structure, the centre of buoyancy can be higher than mid-draft, which will provide the platform with greater stability.

The high values of the new estimated elasticity imply substantial CIT buoyancy effects in the years to come, provided that the current reform program of the Greek economy remains on track.

Abstract:

An essential part of helping kids improve their physical literacy is aquatic education. In addition to encouraging participation in various water environments, aquatic abilities like swimming, floating, and safe entry/exit may save lives in an emergency. Children in industrialized nations are usually trained in swimming pools while being closely watched. Children and babies are frequently observed learning to swim while using supportive devices, such as buoyancy aids. Surprisingly, though, there is conflicting research regarding the best ways and locations for kids to acquire aquatic skills. V

Abstract:

The deep-sea mining hose is a crucial component of the underwater lifting and transport system utilized in deep-sea mining operations. The marine environmental loading and the dynamic coupling between the hose, the subsea mining vehicle, and the relay bin have a complex effect on the mechanical properties of the hose. This study employs the vector form intrinsic finite element method to develop a MATLAB-based three-dimensional dynamic response simulation program for analyzing the hose’s dynamic response characteristics under varying current velocities, buoyancy module quantities, relay bin res

Abstract:

Often used model of turbulent convection from localized sources of buoyancy and (or) momentum acting for a short time – isolated thermals. In such a model, the perturbation region (thermal) is approximately represented as a “bubble” or a vortex ring of variable volume and mass that rises (or descends depending on the perturbation sign). The volume of thermals is gradually increasing due to the capture of adjacent volumes of the environment (“entrainment”). The dynamics of a thermal is described by a nonlinear system of ordinary differential equations – the equations of balance of mass, momentu

Abstract. The overturning streamfunction as measured at the OSNAP (Overturning in the Subpolar North Atlantic Program) mooring array represents the transformation of warm, salty Atlantic Water into cold, fresh North Atlantic Deep Water (NADW). The magnitude of the overturning at the OSNAP array can therefore be linked to the transformation by air–sea buoyancy fluxes and mixing in the region north of the OSNAP array. Here, we estimate these water mass transformations using observational-based, reanalysis-based and model-based datasets. Our results highlight that air–sea fluxes alone cannot acco

The response of a combined dynamic system consisting of a Spar, a mooring line system, and top tension risers is presented. The top tension of a riser is provided by a buoyancy-can that is laterally supported by a preloaded compliant guide. The overall system is nonlinear due to the mooring line restoring force, the friction between the buoyancy-cans and the compliant guides, and the friction between the risers and the guides at the Spar keel. The friction between the Spar and the riser system is captured by a Coulomb model, whereas the stiffness of the mooring line system is accounted for by

The variation of heat and mass transfer processes by RMF can be controlled by selecting a specific frequency and strength of the magnetic field. Both numerical modeling and space-based cr
