The influence of pH on the sorption of pentachlorophenol (PCP) onto three organic amendments, char, humic acid (HA) and peat, and the effect of organic amendments on PCP sorption to three kinds of soils were evaluated. The sorption of PCP on these sorbents fitted the Freundlich model well, suggesting that PCP sorption isotherms were nonlinear with exponential coefficient (N) value lower than 1....

It is generally recognized that heavy timber in fire conditions demonstrates high structural performance. Exposed timber chars which functions as an isolative layer which protects the inner material from heat and loss of load bearing capacity. Char has no significant strength, and therefore, as the char layer grows, the load bearing capacity of the timber member reduces under sustained fire con...

Proof. The intersection P of all subfields of F is a field by Exercise 1.4. Consider the ring homomorphism φ : Z → F given by φ(n) = n · 1. Since any subfield contains 1 and is closed under addition, imφ is contained in P . If Char F = p 6= 0 then imφ is isomorphic to Z/pZ = Fp. Since this is a field, we have P = imφ ∼= Fp. If Char F = 0 then φ is injective. Define φ̂ : Q → F by φ̂(m/n) = φ(m)/φ(...

Chitin-char is obtained from fast pyrolysis of chitin. To obtain the maximum surface area, chitin-char treated by nitric acid. Then, a kind new arsenic removal bio-material prepared loading Ca(OH)2 on char (called Ca(OH)2-char). IR spectroscopy before and after treatment reveal at least three distinct patterns peak changes. An adsorption study performed different doses, pHs, coexisting ions in ...

Carbonaceous adsorbents with controllable surface area and the microporous volume ratio (Vmicro/Vpore) were activated from carbonized corncobs (i.e., char) with KOH etching plus CO2 gasification in this work. Activated carbons derived from KOH/char ratio equal to 1 and CO2 gasification time from 0 to 60 min exhibited BET surface area increasing from 1071 to 1991 m2 g−1 and the Vmicro/Vpore valu...

Continuous human action recognition (CHAR) is more practical in human-robot interactions. In this paper, an online CHAR algorithm is proposed based on skeletal data extracted from RGB-D images captured by Kinect sensors. Each human action is modeled by a sequence of key poses and atomic motions in a particular order. In order to extract key poses and atomic motions, feature sequences are divide...

The goal of this project is to experimentally characterize the high-temperature transformations of coals and alternative solid fuels over a wide range of operating conditions in temperature, pressure, and gas environment. The project will provide the database needed to extend existing submodels of pyrolysis and char burnout to the new conditions anticipated in next-generation energy technologie...

Using massively parallel sequencing data from two species with different life history traits, American lobster (Homarus americanus) and Arctic Char (Salvelinus alpinus), we highlight how an unbalanced sex ratio in the samples and a few sex-linked markers may lead to false interpretations of population structure and thus to potentially erroneous management recommendations. Here, multivariate ana...

gasification is a well-known reaction owing to its relevance to generation of sustainable energyfrom biomass and development of porous carbons. the present paper attempts to experimentally investigate the kinetics of palm shell char gasification using carbon dioxide (co2) in a controlled environment using thermo gravimetric analyzer (tga) at temperatures ranging from 800 to1000°c. a relevant ki...
