Climate variations affect the growth period of young Tectona grandis Linn F. in the Amazon
Acta Botânica Brasílica, 2022 Climate change is expected to increase the occurrence of severe droughts in the tropics, and little is known about its influence on tree dynamics. Tree-ring width and remote sensing tools can help understand the impacts of climate change on tree growth ...

Planetesimal Formation by the Gravitational Instability of Dust Ring Structures
The Astrophysical Journal, 2023 We investigate the gravitational instability (GI) of dust ring structures and the formation of planetesimals by their gravitational collapse. The normalized dispersion relation of a self-gravitating ring structure includes two parameters that are related

Frontiers in Forests and Global Change, 2023 AimsThrough analyzing the responses of the radial growth and element concentrations (B, Mg, Al, K, Ca, Mn, Fe, Zn, Na, P, Ni, and Cu) of tree rings of two dominant tree species to forest fires, we aimed to investigate the relationship between tree rings ...

Trees, 2022 Tree growth in volume and wood density are the two factors that determine tree biomass. They are important for assessing wood quality and resource availability. Analysing and modelling the relationships between these two factors are important for improving silvicultural practices of softwoods like Norway spruce, for which a negative relationship is ...

Numerical Study of Opto-Fluidic Ring Resonators for Biosensor Applications
Sensors, 2012 The opto-fluidic ring resonator (OFRR) biosensor is numerically characterized in whispering gallery mode (WGM). The ring resonator includes a ring, a waveguide and a gap separating the ring and the waveguide.

Plants, 2023 Green alder (Alnus alnobetula), a tall multi-stemmed deciduous shrub, is widespread at high elevations in the Central European Alps. Its growth form frequently leads to asymmetric radial growth and anomalous growth ring patterns, making development of ...

BioResources, 2014 Ring width represents the total width of cells in a growing season. Relatively few studies have identified which of the parameters, cell number, size, or wall thickness is the greater contributor to variations in ring width.

Giant Sequoia Ring-Width Chronologies from the Central Sierra Nevada, California
, 1992 Giant sequoia was one of the first species that A. E. Douglass examined in his pioneering tree- ring research. Recent attention to sequoia, stimulated by fire history studies in sequoia groves, has resulted in new ring-width chronologies based on both ...

Analytical model for double split ring resonators with arbitrary ring width [PDF]
Microwave and Optical Technology Letters, 2007 AbstractFor the first time, the analytical model for a double split ring resonator with unequal width rings is developed. The proposed models for the resonators with equal and unequal widths are based on an impedance matrix representation and provide the prediction of performance in a wide frequency range.

The radial increment of European ash (Fraxinus excelsior L.) under climate change, Ukraine
Journal of Forest Science, 2020 The aim of the study was to compare the response of the radial increment of European ash (Fraxinus excelsior L.) in the Western and Eastern forest steppe of Ukraine to climate change. The growth-climate relationships were estimated for 1961-1987 and 1988-
