SHELL DISEASES AND TOXINS REGULATED BY LAW [PDF]
Croatian Journal of Fisheries, 1999 There is a long tradition of cultivating shells in Croatia, and the shell industry has a good perspective of further development. Since shells are delicate organisms that require special breeding conditions and climate, they are also subject to many ...

Private parts for private property: evolution of penis size with more valuable, easily stolen shells [PDF]
Royal Society Open Science, 2019 Evolution has generated enormous diversity in animal genitalia. However, the importance of private property in driving penis size evolution has rarely been explored.

Shells and feeding bottles: continuity or breach between Greece and Rome?
Layers. Archeologia Territorio Contesti, 2023 The presence of these feeding bottles deposited in graves of Roman Gaul brings forth questions regarding such practice, as the analyses of the contents lead us to link them more to body care.

On large deformations of thin elasto-plastic shells: Implementation of a finite rotation model for quadrilateral shell element [PDF]
, 1997 A large-deformation model for thin shells composed of elasto-plastic material is presented in this work, Formulation of the shell model, equivalent to the two-dimensional Cosserat continuum, is developed from the three-dimensional continuum by employing ...

Development and characterization of agglomerated abrasives based on agro-industrial by-products
Journal of Natural Fibers, 2023 The present work deals with the valorization of agro-industrial by-products to realize bonded abrasives. Four by-products were studied because of their wide availability and mechanical properties: palm nuts shells (Elaeis guineensis), Coco Nucifera ...

International Journal of Geometric Methods in Modern Physics, 2004 We define on-shell symmetries and characterize them for Lagrangian systems. The terms appearing in the variation of the Poincaré–Cartan form, which vanish because of field equations, are found to be strongly constrained if the space of solutions has to be preserved.

Black shells and naked shells [PDF]
International Journal of Geometric Methods in Modern Physics, 2021 In this paper, we study the collapse of a thin dust shell from the point of view of the horizon dynamics. We identify the critical surfaces at which time and space coordinates interchange their roles and investigate their properties by using the formalism of trapped surfaces.

Shelling pseudopolyhedra [PDF]
Discrete & Computational Geometry, 1992 The intersection \(P\) of a family \(\mathcal H\) of closed half-spaces of Euclidean space is called a pseudopolyhedron if for every \(x\in P\) there is a neighborhood of \(x\) having non-empty intersection with at most finite number of the bounding hyperplanes of the half-spaces from \(\mathcal H\).

Hyperspectral cathodoluminescence imaging of modern and fossil carbonate shells
, 2006 Optical cathodoluminescence (CL) is commonly used to identify diagenetically altered carbonate fossils, yet such an interpretation is problematic as present-day carbonate shells may also luminesce.

Adaptive mesh refinements for thin shells whose middle surface is not exactly known [PDF]
, 2008 A strategy concerning mesh refinements for thin shells computation is presented. The geometry of the shell is given only by the reduced information consisting in nodes and normals on its middle surface corresponding to a coarse mesh.
