<title>Abstract</title> This study investigates children’s narrative skills, using the Multilingual Assessment Instrument for Narratives (MAIN), a theory-based tool adapted to 100 languages. How do overall including use of factual and inferred components, development complete episodes, differ across languages between monolinguals bilinguals? To answer this, we examined 2608 comparable fictional narratives 1189 monolingual bilingual children aged 3-13 years, speaking 33 Children told or...
Bench-scale pressure filtration testing was performed to evaluate the dewatering characteristics of two coal refuse slurries, which were collected from thickener underflow streams preparation plants. Pressure provides an opportunity produce drier solids (filter cake) that can be stacked or mixed with coarse and improved water (filtrate) recovery reused in plant. This paper examines effects some major influencing variables such as pressure, slurry pH, feed concentration, fines fraction...

Pressure filtration provides an opportunity for dewatering coal refuse sufficiently to reduce or possibly eliminate the need a slurry impoundment. In this study, pressure was performed in lab-scale unit evaluate nature of slurry, which obtained from preparation facility. Evaluation process using fractional factorial design with cake moisture as response and pressure, pH, solids concentration variables interest. Results indicated decrease increase pH. With pH playing significant role zeta...
Coal refuse slurry impoundments have potential environmental concerns associated with water contamination and impoundment stability. Pressure filtration can be used as an alternative method of handling such coal waste streams it offers opportunity to stack the dewatered solids for subsequent disposal, reducing or eliminating need impoundment. A response surface methodology approach was evaluate effects pH, time, air-blow time on pressure filtration, whose measured in terms final cake...
The effects of pressure and cake thickness were studied using a split-plot design for filtration fine refuse slurry obtained from bituminous coal preparation facility. Pressure offers the potential to significantly reduce moisture content stream with addition little no flocculants, thereby minimizing volume stored in impoundments providing recycle water use within plant. Experimental results showed that final decreased increase decrease thickness. In addition, specific resistances calculated...
Pressure filtration testing was carried out to dewater coal refuse slurry obtained from the thickener underflow stream of an operating preparation facility in Pennsylvania. offers opportunity solids so that they can be stacked for long-term storage, while increasing quantity water available recycling. Lab-, pilot- and bench-scale pressure filters were tested. Results lab-scale plate filter indicated a steep decrease cake moisture first 120 seconds cycle, beyond which further achieved only by...
Pressure filtration of coal refuse slurry has the potential to provide a concentrated solids stream that can be stacked, thereby offering multiple environmental benefits. However, leachates from impact environment. In context, this study performed preliminary investigations application zeolite-based additives adsorb metals leaching at low pH. Additives were added slurry, which was filtered using bench- and lab-scale pressure units. Results indicated overall filtrate flux cake moisture...
