Eulalia picta Kinberg, 1866 – tube builder or specialized predator?
Polish Polar Research, 2017 Twenty six specimens of the polychaete Eulalia picta were found in fine-grained sand tubes. Material was collected in the Antarctic fjord, Admiralty Bay at the depth of about 100 m.

Vertical upward flow patterns in small diameter tubes [PDF]
, 2005 Two-phase flow patterns were studied in vertical small diameter tubes using R134a as the working fluid. The observed flow patterns include bubbly, dispersed bubble, confined bubble, slug, churn, annular and mist flow.

The effect of tube diameter on vertical two-phase flow regimes in small tubes [PDF]
, 2006 Flow boiling flow patterns in four circular tubes with internal diameters of 1.10, 2.01, 2.88 and 4.26 mm were investigated in the present project. The experiments were conducted in vertical upward two-phase flow using R134a as the working fluid.

Prediction of Critical Heat Flux of Mixtures Flowing in Channels
Fluids, 2023 Boiling of mixtures in channels is involved in many chemical processes, and refrigerant mixtures are finding a rapidly increasing use in the refrigeration industries. Hence, reliable prediction of CHF (critical heat flux) is needed. There is no published

Compositionality, 2022 Urn models play an important role to express various basic ideas in probability theory. Here we extend this urn model with tubes. An urn contains coloured balls, which can be drawn with probabilities proportional to the numbers of balls of each colour. For each colour a tube is assumed. These tubes have different sizes (lengths). The idea is that after

On the Number of Tubes Touching a Sphere or a Tube [PDF]
Geometriae Dedicata, 2006 The paper considers three packing problems closely related to the kissing number problem and the Tammes problem. The first two problems are to determine the maximum number of flexible tubes of unit radius that can touch a ball of arbitrary radius in three-space from the outside, or from the inside.
