TLDR
A fluid is a substance in which the constituent molecules are free to move relative to each other, and in a solid, the relative positions of molecules remain essentially fixed under non-destructive conditions of temperature and pressure.Abstract:
A fluid is a substance in which the constituent molecules are free to move relative to each other Conversely, in a solid, the relative positions of molecules remain essentially fixed under non-destructive conditions of temperature and pressure While these definitions classify matter into fluids and solids, the fluids subdivide further into liquid and gasesread more

Aerodynamic forces on a high-voltage delta-configuration lattice transmission tower segment
TL;DR: In this article, the aerodynamic properties of the upper segment of a highvoltage delta-configuration (cat-head) lattice transmission tower were analyzed in wind tunnel tests.

Trophic guilds of suction-feeding fishes are distinguished by their characteristic hydrodynamics of swimming and feeding
TL;DR: The scaling of dynamic similarity across species, body sizes and feeding guilds in fishes indicates that elementary hydrodynamic principles govern the trophic evolution of suction-feeding in fishes.

Evidence for Ventilation through Collective Respiratory Movements in Giant Honeybee (Apis dorsata) Nests
TL;DR: Ventilation of the bee curtain is suggested by IR imaging and laser vibrometry depicting CNRs in at least four aspects as low-resistance convection funnels for maintaining thermoregulation and restoring fresh air in the nest.
Non-Hydrostatic Modelling of Waves in Layered Fluids
TL;DR: In this article, a non-hydrostatic two-layer 2DV model, based on the scheme presented by Stelling and Zijlema (2003), is developed, where the velocities are corrected with a pressure gradient following from the requirement of a divergence free flow field per computational cell.
Nanomechanics – Quantum Size Effects, Contacts, and Triboelectricity
TL;DR: In this paper, the nano-scale is defined as 1 to 100 nanometers and some phenomena are of crucial importance, while the s s is not of critical importance at the macroscopic scale.
