Quantifiable impact: monitoring landscape restoration from space. A regreening case study in Tanzania

Frontiers in Environmental Science
The impact of ecosystem conservation and restoration activities are rarely monitored from a global, multidimensional and multivariable perspective. Here we present an approach to quantify the environmental impact of landscape restoration using long-term ...

JARAK MINIMUM ORBIT DAN TUMBUKAN POPULASI ASTEROID DEKAT-BUMI DENGAN PLANET BUMI [PDF]

Wahana Fisika: Jurnal Penelitian Fisika dan Terapannya, 2020
Asteroid dekat-Bumi diketahui memiliki orbit yang kaotik akibat seringnya terjadi papasan dekat dengan planet-planet terestrial. Orbit yang kaotik dapat membuat populasi objek ini berakhir sebagai penumbuk matahari maupun planet-planet.

Radiative Transfer on Perturbations in Protoplanetary Disks

, 2003
We present a method for calculating the radiative tranfer on a protoplanetary disk perturbed by a protoplanet. We apply this method to determine the effect on the temperature structure within the photosphere of a passive circumstellar disk in the ...

An Earth-Sized Planet in the Habitable Zone of a Cool Star [PDF]

Science, 2014
Starry Brightness The high photometric precision of NASA's Kepler observatory has enabled the detection of many planets because they cause slight dimming of their host stars as they orbit in front of them. From these data, Quintana et al. (p.
