TLDR
The emergence in the laboratory of a streamwise dissolution pattern at the surface of an initially flat soluble material, inclined and subjected to a thin runoff water flow is reported.Abstract:
The dissolution of rocks by rainfall commonly generates streamwise parallel channels, yet the occurrence of these natural patterns remains to be understood. Here, we report the emergence, in the laboratory, of a streamwise dissolution pattern at the surface of an initially flat soluble material, inclined and subjected to a thin runoff water flow. Nearly parallel grooves of width about one millimeter and directed along the main slope spontaneously form. Their width and depth increase continuously with time, until their crests emerge and channelize the flow. Our observations may constitute the early stage of the patterns observed in the field.read more

TL;DR: While the book is a standard fixture in most chemical and physical laboratories, including those in medical centers, it is not as frequently seen in the laboratories of physician's offices (those either in solo or group practice), and I believe that the Handbook can be useful in those laboratories.
Nonlinear and subharmonic stability anaysis in film-driven geomorphological patterns
TL;DR: As finite-amplitude monochromatic waves may be destabilized by nonlinear interactions with other modes, it is verified, through center manifold projection, the stability of the fundamental to subharmonic disturbances.

Onset of Glacier Tables.
TL;DR: In this article, the authors investigate the onset of the formation of a glacier table at a smaller scale in a controlled environment and identify a dimensionless number which controls the onset time of glacier table formation.

A new dynamic masking technique for time resolved PIV analysis
TL;DR: A new DM technique is presented which envisages, along with a dedicated masking algorithm, the employment of fluorescent coating to allow for accurate tracking of the object and compares the proposed algorithm with both a no-masking and a static masking solution.

The hydrodynamic genesis of linear karren patterns
TL;DR: In this paper, a hydrodynamic model for the formation of dissolutional patterns made of parallel longitudinal channels, commonly referred to as linear karren forms, is presented, which addresses a laminar film of water flowing on a rock that is dissolving.

The mathematics of diffusion
TL;DR: Though it incorporates much new material, this new edition preserves the general character of the book in providing a collection of solutions of the equations of diffusion and describing how these solutions may be obtained.

The structure of turbulent boundary layers
TL;DR: In this article, the authors describe the formation of low-speed streaks in the region very near the wall, which interact with the outer portions of the flow through a process of gradual lift-up, then sudden oscillation, bursting, and ejection.
