A Unified Mechanism on the Formation of Acenes, Helicenes, and Phenacenes in the Gas Phase. [PDF]
, 2020 A unified low-temperature reaction mechanism on the formation of acenes, phenacenes, and helicenes-polycyclic aromatic hydrocarbons (PAHs) that are distinct via the linear, zigzag, and ortho-condensed arrangements of fused benzene rings-is revealed. This

Validation of Four Meteorological Drought Indices Based on the Growth Rings Beech, Poplar, and Willow in the Mashhad Area [PDF]
مهندسی منابع آب, 2013 Water resources management and its planning are increasingly impact by the climate change, especially in the arid and semi arid area. As the tree rings integrate the effects of internal water stress, their thickness maybe correlated with the amount and ...

Dust and Gas in the disc of HL Tauri: Surface density, dust settling, and dust-to-gas ratio [PDF]
, 2015 The recent ALMA observations of the disc surrounding HL Tau reveal a very complex dust spatial distribution. We present a radiative transfer model accounting for the observed gaps and bright rings as well as radial changes of the emissivity index.

Tree Growth Rings in Tropical Peat Swamp Forests of Kalimantan, Indonesia
, 2017 Tree growth rings are signs of the seasonality of tree growth and indicate how tree productivity relates to environmental factors. We studied the periodicity of tree growth ring formation in seasonally inundated peatlands of Central Kalimantan (southern ...

La formación de anillos de crecimiento en Fissurella crassa en el norte de Chile
Brazilian Journal of Oceanography, 1980 Growth discontinuity in molluscs result in the formation of rings on their shells. Two kind of rings may be formed: disturbance and growth rings. Growth rings can be used to determine the age of molluscs with long life span.
