On the equivalence between the cell-based smoothed finite element method and the virtual element method

We revisit the cell-based smoothed finite element method (SFEM) for quadrilateral elements and extend it to arbitrary polygons and polyhedrons in 2D and 3D, respectively. We highlight the similarity between the SFEM and the virtual element method (VEM). Based on the VEM, we propose a new stabilization approach to the SFEM when applied to arbitrary polygons and polyhedrons. The accuracy and the convergence properties of the SFEM are studied with a few benchmark problems in 2D and 3D linear elasticity. Later, the SFEM is combined with the scaled boundary finite element method to problems involving singularity within the framework of the linear elastic fracture mechanics in 2D

On the breeding habits of the Cowry Erronea errones (Linne)

Cowries are fairly common in the shallow a reas of Palk Bay and Gulf of Mannar. The species commonly found in the area between Mandapam Camp and Mandapam has been ide ntified as Erronea errones (Linne

Studies on the egg masses and larval development of some Prosobranchs from the Gulf of Mannar and the Palk Bay

In recent years our knowledge of the eggs and larvae of marine gastropods has increased considerably. The investigations of Lebour (1937) and Thorson (1946) have added much to our knowledge of the eggs and larvae of prosobranchs from Plymouth and Danish waters. Francis (1948) investigations at Algiers and Banyuls supplement at many points the work of Lebour and Thorson
