Understanding fine-scale variability in understory fuels is increasingly important as physics-based fire behavior models drive needs for higher-resolution data. Describing fuelbeds 3Dly is critical in determining vertical and horizontal distributions of fuel elements and themass, especially in frequently burned pine ecosystems where fine-scale fuels arrangement drives fire intensity and resulti...

Fires in open plan compartments have been the subject of much research over past decade. This article presents results from an experimental study conducted to explore factors that influence fire dynamics open-plan with exposed timber ceiling. A reduced scale testing methodology is proposed and supported by contrasting observed behaviour at small large-scale experiments reported literature. The ...

The toxic smoke production of four rainscreen façade systems were compared during large-scale fire performance testing on a reduced height BS 8414 test wall. Systems comprising ‘non-combustible’ aluminium composite material (ACM) with polyisocyanurate (PIR), phenolic foam (PF) and stone wool (SW) insulation, polyethylene-filled ACM PIR insulation tested. Smoke toxicity was measured by sampling ...

We present a framework for the joint recovery of the shape and reflectance of an object with dichromatic BRDF, using motion cues. We show that four (small or differential) motions of the object, or three motions of the camera, suffice to yield a linear system that decouples shape and BRDF. The theoretical benefit is that precise limits on shape and reflectance recovery using motion cues may be ...

ANTOINE LAVOISIER FAThER OF mOdERN chEmISTRy Antoine Laurent Lavoisier (1743-1794) was born in Paris. One of the great figures in science, he is often called father of modern chemistry. Priestly, in 1774 had heated brick red calx (mercuric oxide), obtaining back mercury, and in addition a combustible gas, with most unusual properties, He called it “dephlogisticated air” (oxygen). It was held th...

Latent fingerprints are commonly recovered from crime scenes using tape lifts. Advancements in the sensitivity of DNA testing allow for DNA profiles from these “touch”, tape lift samples to be obtained. One drawback to DNA typing of tape lifts is that the adhesive material on the tape may inhibit DNA recovery. The purpose of this study was to maximize the recovery of DNA from the adhesive mater...

An experimental and numerical study was performed on the interaction of combustible solid particles with atmospheric, strained, laminar premixed methane/air and propane/air flames in normal gravity. The study was conducted in the opposed-jet configuration in which a single flame was stabilized below the gas stagnation plane by counterflowing a mixture against an air jet. Into the flame were see...

The paper presents the results of thermodynamic calculations and experimental studies plasma processing biomedical waste fuel biomass, including from woodworking industry agriculture, which have shown promise using plasma-chemical technology for various wastes with production combustible gas inert mineral material. Comparison showed their satisfactory agreement. Both in experiments, no harmful ...

The aim of the paper is to highlight importance calorific properties softwood biomass. presents caloric power and ash content, important in assessment wood Biomass, form wood, was will remain an combustible material. value content for spruce 3.8% 4.2% fir. These values are within international standards. Wood biomass, as a material can provide energy need population at reduced price. combustion...
