The Electronic Library SPELL (Scientific Periodic Electronic Library) is a free repository of scientific papers and aims to provide access to scientific and technical information.
A Spell também permite ao usuário selecionar vários registros resultantes de diferentes procedimentos de busca e salvá-los em uma pasta temporária, chamada Minha Pasta. O usuário pode enviar um arquivo de cada vez ou em lote para a Minha Pasta, por meio da função Spell It. Depois disso, pode continuar pesquisando na Spell normalmente.
Geometry is, along with arithmetic, one of the oldest branches of mathematics. A mathematician who works in the field of geometry is called a geometer.

Geometry, the branch of mathematics concerned with the shape of individual objects, spatial relationships among various objects, and the properties of surrounding space.
Geometry is all about shapes and their properties. If you like playing with objects, or like drawing, then geometry is for you!
Two types of geometry are plane geometry and solid geometry. Plane geometry deals with two-dimensional shapes and planes (x-axis and y-axis), while solid geometry deals with three-dimensional objects and 3D planes.
