To predict fuel moisture contents of Hong-reung arboretum in South Korea

open access: yesBiodiversidade Brasileira, 2019
Recently, on the Korean Peninsula, large scale forest fire frequently occurs every year from 2017 (Gangneung, Sanchuck), 2018 (Gosung), 2019 (Sockcho, Gangneung).

Silviculture can facilitate repeat prescribed burn programs with long-term strategies

open access: yesCalifornia Agriculture, 2022
A significant expansion of prescribed fire activity will be necessary to mitigate growing wildfire hazard in California forests. Forest managers can facilitate this expansion by promoting forest structures that allow for more effective implementation of ...

Estimating Leaf Bulk Density Distribution in a Tree Canopy Using Terrestrial LiDAR and a Straightforward Calibration Procedure

open access: yesRemote Sensing, 2015
Leaf biomass distribution is a key factor for modeling energy and carbon fluxes in forest canopies and for assessing fire behavior. We propose a new method to estimate 3D leaf bulk density distribution, based on a calibration of indices derived from T ...

A Full-Waveform Airborne Laser Scanning Metric Extraction Tool for Forest Structure Modelling. Do Scan Angle and Radiometric Correction Matter?

open access: yesRemote Sensing, 2020
In the last decade, full-waveform airborne laser scanning (ALSFW) has proven to be a promising tool for forestry applications. Compared to traditional discrete airborne laser scanning (ALSD), it is capable of registering the complete signal going through

Hypolipidemic activities of partially deacetylated α-chitin nanofibers/nanowhiskers in mice

open access: yesFood & Nutrition Research, 2018
Partially deacetylated α-chitin nanofibers/nanowhiskers mixtures (DEChNs) were prepared by 35% sodium hydroxide (NaOH) treatment followed by disintegration in water at pH 3–4.

Mathematical Modeling of Forest Fire Containment Using a Wet Line Ahead of the Combustion Front

open access: yesFire, 2023
The modern methods of predicting the fire front spread characteristics during forest fires have significant limitations. The main challenge is to adequately describe the impact of the flame length (reaching 10–15 m even during surface fires) on the fire ...

Human ignitions on private lands drive USFS cross-boundary wildfire transmission and community impacts in the western US

open access: yesScientific Reports, 2022
Wildfires in the western United States (US) are increasingly expensive, destructive, and deadly. Reducing wildfire losses is particularly challenging when fires frequently start on one land tenure and damage natural or developed assets on other ...

Simulation of harvester productivity in selective and boom-corridor thinning of young forests [PDF]

open access: yes, 2012
Forest management practices may change in the future, due to increases in the extraction of forest fuel in first thinnings. Simulation models can be used to aid in developing new harvesting systems.

Processing and analysis of airborne full-waveform laser scanning data for the characterization of forest structure and fuel properties

open access: yesRevista de Teledetección, 2020
This PhD thesis addresses the development of full-waveform airborne laser scanning (ALSFW) processing and analysis methods to characterize the vertical forest structure, in particular the understory vegetation.

Effect of fire spread, flame characteristic, fire intensity on particulate matter 2.5 released from surface fuel combustion of Pinus koraiensis plantation– A laboratory simulation study

open access: yesEnvironment International, 2022
PM2.5 is one of major pollutants emitted from forest fires. High PM2.5 concentration not only affects short-term human respiration health, but also poses a long-term threat to human cardiopulmonary functionality.
