Many of these are single-teacher schools, where the teachers lack the skill and training to impart quality education to students. DSH makes the content in local language according to respective state curricula from urban hubs like Lucknow and Pune.

Employees generate ideas for projects, prepare annual activity plans, implement each activity, and monitor results. To fund these employee initiatives, each sector targets to donate 0.5 percent of its profit after tax to the central CSR fund and 0.5 percent to Esops. Education is one of the strongest categories of Esops activity. We support local schools, children’s homes, and educational institutions with stationery, books, bags, uniforms, and building materials.

MELBOURNE -- "It was Friday, July 15, 2011," Loren O'Keeffe states without faltering, pinpointing the day her then-24-year-old brother Dan went (and remains) missing from their home in Geelong, a regional town on the outskirts of Melbourne.

When the 29-year-old turned to the police for help they said only missing cases that are deemed suspicious (thus criminal) by police are allocated search resources. O'Keeffe decided to take matters into her own hands, with her efforts culminating in the establishment of Missing Persons Advocacy Network (MPAN), a non-profit organization that offers an actionable how-to kit that enables anyone to conduct their own missing persons search.

Ignite NIF. Future solar cells may be made of wood. ( —A new kind of paper that is made of wood fibers yet is 96% transparent could be a revolutionary material for next-generation solar cells. Coming from plants, the paper is inexpensive and more environmentally friendly than the plastic substrates often used in solar cells. However, its most important advantage is that it overcomes the tradeoff between optical transparency and optical haze that burdens most materials.

A team of researchers from the University of Maryland, the South China University of Technology, and the University of Nebraska-Lincoln, have published a paper on the new material in a recent issue of Nano Letters. As the researchers explain, solar cell performance benefits when materials possess both a high optical transparency (to allow for good light transmission) and a high optical haze (to increase the scattering and therefore the absorption of the transmitted light within the material).
