Radiocarbon Ecology of the Land Snail Helix Melanostoma in Northeastern Libya [PDF]
, 2017 Terrestrial gastropods are problematical for radiocarbon (14C) measurement because they tend to incorporate carbon from ancient sources as a result of their dietary behavior.

On characteristic curves of developable surfaces in Euclidean 3-space [PDF]
arXiv, 2015 We investigate the relationship among characteristic curves on developable surfaces. In case parameter curves coincide with these curves, we show that the base curve of a developable surface could be either a plane curve, a circular helix, a general helix or a slant helix.

Neuronal background of positioning of the posterior tentacles in the snail Helix pomatia [PDF]
, 2013 The location of cerebral neurons innervating the three recently described flexor muscles involved in the orientation of the posterior tentacles as well as their innervation patterns were investigated, applying parallel retrograde Co- and Ni-lysine as ...

Thermodynamics of helix-coil transitions studied by multicanonical algorithms [PDF]
arXiv, 1995 Thermodynamics of helix-coil transitions in amino-acid homo-oligomers are studied by the recently proposed multicanonical algorithms. Homo-oligomers of length 10 are considered for three characteristic amino acids, alanine (helix former), valine (helix indifferent), and glycine (helix breaker).

Genetic diversity in fishery-exploited populations of the banded murex ("Hexaplex trunculus") from the southern Iberian Peninsula [PDF]
, 2008 [Abstract] This study presents an analysis of the genetic diversity in Hexaplex trunculus from three localities of the southern Iberian Peninsula (Ria Formosa and Ria de Alvor in Portugal, and Río Piedras in Spain) using three mitochondrial (12S rRNA ...

f-Eikonal helix submanifolds and f-Eikonal helix curves [PDF]
arXiv, 2012 Let M{\subset}\mathbb{R}^{n} be a Riemannian helix submanifold with respect to the unit direction d{\in}\mathbb{R}^{n} and f:M{\to}\mathbb{R} be a eikonal function. We say that M is a f-eikonal helix submanifold if for each q{\in}M the angle between {\nabla}f and d is constant.Let M{\subset}\mathbb{R}^{n} be a Riemannian submanifold and {\alpha}:I{\to ...
