Planting and replanting: Continuity and change over four decades of forest restoration in Himachal Pradesh, India

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
India has a long history of planting trees to restore ecosystem services providing an opportunity to evaluate long‐term ecosystem restoration processes. We show that these programs have shifted over time in response to public demands as well as through changes in the government's vision for forests.

Investigation of Al/SrO2/MgSt and Si/CaO2/MgSt Delay Pellets and Parameters Influencing the Burning Rate As Well As Thermal Aging Effects on Their Burning Properties

open access: yesPropellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Toxic and environmentally harmful components of pyrotechnic compositions require to be substituted with alternative substances. Therefore, the subject of this work was the burning rate investigation of the Al/SrO2 and Si/CaO2 pyrotechnic delay compositions.
