Spatial metrics in fire ecology: seeking consistency amidst complexity
ABSTRACT Technological advances, including remote sensing, have led to a proliferation of metrics used in ecological studies to examine spatial patterns of fire regimes and their ecological effects. Researchers can use many different metrics to analyse spatial variation in both fire events and resulting fire regimes, including fire size, shape ...

Modified model of Newtonian gravitation.
Within the limits of the classical mechanics for planets of the Solar system a new form of gravitational potential is suggested. The following effects are considered: perihelion advance of the planets, deviation of light beams in the field of the Sun ...

Ice On Planets of the Solar System [PDF]
AbstractSeveral aspects of space glaciology are considered in the paper. Estimates of the water content of the Earth, Mars, and the Galilean moons of Jupiter are corrected. A considerable proportion of the total amount of water in the solar system is localized near Jupiter; part of this water is contained as ice in glaciations, glacial caps, and ice ...

ABSTRACT The blue economy has emerged as a key sector for linking sustainability and innovation, yet existing research has largely overlooked how firms operationalize these processes in practice. This study addresses that gap by asking: How do Portuguese blue economy firms embed sustainability‐oriented innovation (SOI) into their strategies, and what ...

ABSTRACT This study examines how carbon accounting can be used to govern, not merely report, circular economy principles in shipping corporations. Grounded in institutional theory and aligned with the UN 2030 Agenda, this study introduces circular harmony as an accounting design principle: Circular interventions are embedded in a single well‐to‐wake ...

PROCESS OF PLANETS’ MAGNETIC FIELDS FORMATION
Heated melt of the cores of the Sun and the planets is the basis of their permanent magnetic fields that, in interaction with the large-scale magnetic field of the Galaxy, condition on the action of their dynamo mechanisms which, on the basis of the ...

The Sun is depleted in refractory elements compared to nearby solar twins, which may be linked to the formation of giant or terrestrial planets. Here we present high-resolution, high signal-to-noise spectroscopic data for 17 solar-like stars hosting ...

KOI-3158: The oldest known system of terrestrial-size planets
The first discoveries of exoplanets around Sun-like stars have fueled efforts to find ever smaller worlds evocative of Earth and other terrestrial planets in the Solar System. While gas-giant planets appear to form preferentially around metal-rich stars,

Giant planets: Clues on current and past organic chemistry in the outer solar system [PDF]
The giant planets of the outer solar system - Jupiter, Saturn, Uranus, and Neptune - were formed in the same flattened disk of gas and dust, the solar nebula, as the terrestrial planets were.

ABSTRACT This paper contributes to venture‐creation research by examining how sustainable startups can overcome market constraints to drive transformative change through their business development. Conceptually, we address this question by identifying venture‐creation narratives in the learning and experimental phases of sustainable startups that ...
