Analysis spatial distribution trees in forest stands [PDF]

open access: yesGlasnik Šumarskog Fakulteta: Univerzitet u Beogradu, 2006
The analyses of the horizontal distribution of trees have not been used in the research of stand structure in Serbia’s forestry to date. Taking into account the high economic and ecological applicability of such information, this paper deals with the ...

Refractive index characteristics of edible oils based on spectrometry and effects of oil dispersion on OCT

open access: yesJournal of Innovative Optical Health Sciences, 2021
It is necessary to investigate the wavelength-dependent variation rules of the refractive index of edible oils so as to explore the specificity of the dispersion in light propagation, imaging, and interference processes among different types of edible ...

Dispersion of Knee Helical Axes during Walking after Maximal versus Resistant Strength Training in Healthy Subjects

open access: yesApplied Sciences, 2022
Knee joint stability can be estimated during functional tasks through the analysis of the helical axes (HAs) dispersion. The study aimed at investigating (1) the test–retest reliability of knee HAs dispersion during walking and (2) the effects of maximal

Effect of drying dynamics on the functional structure of a fish assemblage from an intermittent river network

open access: yesFrontiers in Environmental Science, 2022
We are living in a fast-changing world promoted by anthropogenic actions and ecosystems’ functioning has been constantly changed. One example is the globally reduction of river flow that can lead to more than 50% of the rivers and streams around the ...

The Turbulence Spectrum of Molecular Clouds in the Galactic Ring Survey: A Density-Dependent PCA Calibration [PDF]

open access: yes, 2011
Turbulence plays a major role in the formation and evolution of molecular clouds. The problem is that turbulent velocities are convolved with the density of an observed region.

Sub-Alfvenic Non-Ideal MHD Turbulence Simulations with Ambipolar Diffusion: I. Turbulence Statistics [PDF]

open access: yes, 2008
Most numerical investigations on the role of magnetic fields in turbulent molecular clouds (MCs) are based on ideal magneto-hydrodynamics (MHD). However, MCs are weakly ionized, so that the time scale required for the magnetic field to diffuse through ...

Distribuição espacial de cupinzeiros epígeos de pastagem no município de Iporá-GO, Brasil

open access: yesEntomoBrasilis, 2011
Cupins (Isoptera) são insetos sociais que vivem agrupados em cupinzeiros com elevada densidade, o que dificulta a estimativa de parâmetros populacionais, por isso, a abundância de cupins é feita pela contagem de ninhos. O objetivo foi estimar o padrão de

Numerical Simulation of Three-Core Photonic Crystal Fiber With Large Group-Velocity Dispersion

open access: yesIEEE Access, 2020
The three-core photonic crystal fiber (TC-PCF) is proposed to obtain large group-velocity dispersion (GVD) because of the coupling effects between the fundamental modes (FMs) of the central core and higher-order modes (HOMs) of the two side cores.
