Agnes Smedley

American feminist Agnes Smedley played a key role in assisting Indian freedom fighters in the U.S. and in Europe in the beginning of the th century. An unbashed feminist, fearless journalist and writer as well as relentless activists for the causes she believed in, Smedley inspired socially concerned writers like Alice Walker, because she wrote about povetry without romanticizing it. The span of her activism covered the three continents - America , Europe, and Asia. During World war I , Smedley grew close with Lala Lajpat Rai, M.N.Roy and Sailendranath Ghose and agreed to serve as communication centre for Indian revoloutionaries then in US. In 1929, she finished her autobiographical novel Daughter of Earth.

Item Response Theory(IRT)

Item Response Theory(IRT) attempts to model students ability using question level performance instead of aggregate test level performance. Instead of assuming all questions contribute equally to our understanding of a students abilities, IRT provides a more nuanced view on the information each question provides about a student. The Human Resource Development ministry and NCERT carried out a survey using the IRT to test the learning curve of class III, V and VIII.

Dry cask storage

Dry cask storage is a method of storing high-level radioactive waste, such as spent nuclear fuel that has already been cooled in thespent fuel pool for at least one year and often as much as ten years. Casks are typically steel cylinders that are either welded orbolted closed. The fuel rods inside are surrounded by inert gas. Ideally, the steel cylinder provides leak-tight containment of the spent fuel. Each cylinder is surrounded by additional steel, concrete, or other material to provide radiation shielding to workers and members of the public.
