The control of soluble metal species in the sub-product leachate generated in electricity production processes is of great concern from an environmental and health point of view. Unlike fly ash, the leaching behaviour of char materials has received little attention. Yet, these solids are captured together with fly ashes in the particle control devices of power plants and are emitted in the same...

A low SV causes relatively slow pyrolysis conditions at around 600°C, and produces high yields of charcoal 20-30%, large quantities of unburned tars, and a gas with high hydrocarbon content and high tar (volatile) content. A high SV causes very fast pyrolysis, producing less than 10% char-ash at 1050 C and hot gases at 1200-1400 C in the flaming pyrolysis zone. These gases then react with the r...

Abstract Textile dyes are causing serious environmental problems in the world. The treatment of from textile wastewater is necessary to protect environment. Adsorbents with high adsorption potential local materials required solve these problems. In this study, acid yellow 17 dye aqueous solutions was carried out using an activated bone char, collected slaughterhouses. removal performance measur...

—Using six microsatellite loci, we characterized the 12 remaining populations of Arctic char Salvelinus alpinus naturally occurring in Maine. More specifically, we challenged the hypotheses based on previous analyses with other markers that (1) Arctic char from Floods Pond (known locally as silver char) represent a distinct evolutionary lineage and (2) all other Arctic char populations from Mai...

We propose a method that is able to analyze chaotic time series, gained from experimental data. The method allows to identify scalar time-delay systems. If the dynamics of the system under investigation is governed by a scalar time-delay differential equation of the form dy(t) dt = h(y(t), y(t−τ0)), the delay time τ0 and the function h can be recovered. There are no restrictions to the dimensio...

In this work, the backward Bayesian multiple linear regression (BBMLR) as a new approach is presented to predict the adsorption efficiency (AE) of Cd(II) ions by ostrich bone char (OBC) in the fixed bed adsorption with four operational variables consisting of pH (2-9), inlet Cd(II) concentration (Co= 25-100 mg/L), bed depth (h= 3-9 cm) and feed flow rate (Q= 0.5-30 mL/min). The performance of t...
