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

Multi-modal locomotor costs favor smaller males in a sexually dimorphic leaf-mimicking insect

TL;DR: In this paper , a combination of empirical measures of flight performance and modelling of body aerodynamics was used to show that large body size impairs flight performance in male leaf insects (Phyllium philippinicum), a species where relatively small and skinny males fly through the canopy in search of large sedentary females.

Lubricity and tribological properties of dicarboxylic acid and oleyl alcohol based esters
TL;DR: In this paper, eight diesters with different chemical structures were tested in terms of their suitability as lubricants and the results indicated that all the diesters studied can be used as lubricating base oils.

A Modified Cubic Law for Rough-Walled Marble Fracture by Embedding Peak Density
TL;DR: In this article, a modified cubic law was put forward to present the relationship between the seepage characteristics of a rough rock fracture and peak density of two fracture surfaces, and the results showed a relatively good agreement.
Instalação e capacidade de carga axial de estacas modelo fluidizadas em solos arenosos
TL;DR: Passini et al. as discussed by the authors investigated the feasibility of using circular vertical water jets, single and continuous, from the tip of a torpedo pile, to assist its installation by own weight on the seabed, through soil fluidization.
ReportDOI
Velocity boundary conditions for vorticity formulations of the incompressible Navier-Stokes equations
TL;DR: In this paper, the velocity boundary conditions for the vorticity form of the incompressible, viscous fluid momentum equations are presented, and a kinematical formulation of the newly created vortivity is specified by a kineratic formulation which is a generalization of the Helmholtz decomposition of a vector field.

TL;DR: Nikuradse as discussed by the authors showed that the resistance law of the Karman-Prandtl theory for smooth surfaces was satisfactorily satisfied with respect to the size of roughness grains.
