A Mathematical Model for Simulating Meteor Showers
Trends in Computational and Applied Mathematics, 2019 This paper presents a mathematical model to simulate the trajectory of a meteor as seen by a single observer located anywhere on Earth. Our strategy is to define a new coordinate system, called Radiant Coordinate System, which is centered on the observer

Deep Groundwater Total Dissolved Solids Mapping in the Dakota Group, Williston Basin, USA
Groundwater, EarlyView.Abstract Growing concern about the quantity of available freshwater around the world has led to interest in surveying groundwater total dissolved solids (TDS) below water well depths. Deep TDS has not been systematically mapped, and there is much to learn about the distribution and controls on deeper groundwater. In sedimentary basins across the United

Earth and Planetary PhysicsOptical monitoring of fireballs can provide reconstructions of luminous trajectories and the derivation of heliocentric orbits, whereas spectral observations are able to supply information from an entirely different perspective, with composition and ...

Exploring Complex Historical Figures through a Modified Critical Making Framework
International Journal of Art &Design Education, EarlyView.Abstract This paper examines ‘critical making’ as a framework for exploring complex problems and topics. Critical making combines an iterative process of making with research, reflection and analysis. The authors present a modified critical making process that builds on the reflexive material engagement introduced by the originator of critical making ...

Journal of Fish Biology, EarlyView.Abstract Deep‐sea elasmobranchs are less resilient to the increasing scale of anthropogenic impacts such as fisheries, owing to their life‐history traits. The necessity for proper management measures is hampered by the scant knowledge on these taxa and their biology. Here we provide the first comprehensive insight into the parasite infracommunities and

STATISTICAL CHARACTERISTICS OF HYPERBOLIC ORBITS METEORS
Odessa Astronomical Publications, 2017 We present statistical data on the distribution of orbital elements and parameters of interstellar sporadic hyperbolic meteors. We show that for some of them there is a proximity of their orbits with the Earth's orbit that can be interpreted as evidence ...
