Impacts of urbanization and tourism on the erosion and accretion of European, Asian and African coastal areas and possible solutions [PDF]
Urbanism. Arhitectura. Constructii, 2020 Coastal areas are very important due to the ecosystem services provided to the inhabitants. However, these advantages have resulted into an increasing attraction, especially in the recent centuries.

The Three Dimensional Structure of EUV Accretion Regions in AM Herculis Stars: Modeling of EUV Photometric and Spectroscopic Observations [PDF]
, 1998 We have developed a model of the high-energy accretion region for magnetic cataclysmic variables and applied it to {\it Extreme Ultraviolet Explorer} observations of 10 AM Herculis type systems.

Evolution of Interstellar Medium, Star Formation, and Accretion at High Redshift [PDF]
, 2017 ALMA observations of the long wavelength dust continuum are used to estimate the interstellar medium (ISM) masses in a sample of 708 galaxies at z = 0.3 to 4.5 in the COSMOS field.

Magellan Adaptive Optics Imaging of PDS 70: Measuring the Mass Accretion Rate of a Young Giant Planet within a Gapped Disk [PDF]
Astrophysical Journal Letters, 2018 PDS 70b is a recently discovered and directly imaged exoplanet within the wide (≳40 au) cavity around PDS 70. Ongoing accretion onto the central star suggests that accretion onto PDS 70b may also be ongoing.

Mass Transfer in Mira-Type Binaries
Open Astronomy, 2012 Detached, symbiotic binaries are generally assumed to interact via Bondi-Hoyle-Littleton (BHL) wind accretion. However, the accretion rates and outflow geometries that result from this mass-transfer mechanism cannot adequately explain the observations of

Acclimatization Drives Differences in Reef-Building Coral Calcification Rates
Diversity, 2020 Coral reefs are susceptible to climate change, anthropogenic influence, and environmental stressors. However, corals in Kāneʻohe Bay, Hawaiʻi have repeatedly shown resilience and acclimatization to anthropogenically-induced rising temperatures and ...

Phantom energy accretion and primordial black holes evolution in Brans-Dicke theory [PDF]
Eur. Phys. J. C 71, 1837 (2011), 2011 In this work, we study the evolution of primordial black holes within the context of Brans-Dicke theory by considering the presence of a dark energy component with a super-negative equation of state called phantom energy as a background. Besides Hawking evaporation, here we consider two type of accretions - radiation accretion and phantom energy ...

Self-Similar Solution of Hot Accretion Flow with Anisotropic Pressure
Universe, 2019 For the accretion flow in extremely low-luminosity active galactic nuclei, such as our Galactic center (Sgr A*) and M 87, the collisional mean-free path of ions may be much larger than its gyroradius.
