Flower production prospects and sustainability challenges in Ethiopia: A systematic review
The people, planet, and profit sustainability concerns emerged as a novel concept in the ethical business governance system in the floriculture industry. In Ethiopia, however, the sectoral sustainability concern is in its infant stage.

PLANET-PLANET SCATTERING IN PLANETESIMAL DISKS [PDF]
We study the final architecture of planetary systems that evolve under the combined effects of planet-planet and planetesimal scattering. Using N-body simulations we investigate the dynamics of marginally unstable systems of gas and ice giants both in isolation and when the planets form interior to a planetesimal belt.

Tilting Planets during Planet Scattering [PDF]
Abstract Observational constraints on planetary spin axis have recently become possible, and they have revealed a system that favors large spin-axis misalignment, low stellar spin–orbit misalignment, and high eccentricity. To explain the origin of such systems, we propose a mechanism that could tilt the planetary spin axis during planet ...

Dynamical Outcomes of Planet‐Planet Scattering [PDF]
Observations in the past decade have revealed extrasolar planets with a wide range of orbital semimajor axes and eccentricities. Based on the present understanding of planet formation via core accretion and oligarchic growth, we expect that giant planets often form in closely packed configurations.

Ontosonographic Maps: Toward a Theoretization of Soundscape Forms in the Anthropocene Epoch
This paper deals with the ways in which it is possible to conceptualize and map forms of soundscape in the epoch of the Anthropocene. After humans became a geological force, which is a role that used to be reserved for the planet itself, one can pose the

A new family of planets? “Ocean-Planets” [PDF]
A new family of planets is considered which is between rochy terrestrial planets and gaseous giant ones: "Ocean-Planets". We present the possible formation, composition and internal models of these putative planets, including that of their ocean, as well as their possible Exobiology interest.
