Pulsed energization of electrostatic precipitator (ESP) may represent one of the most promising solutions to comply with strict environmental regulation in case of high resistivity dust. Performs a parametric cost comparison between conventional and pulsed ESP with reference to four main industrial areas: electric power generation, cement manufacturing, iron and steel production, glass industry...

NiAl layered double hydroxides (LDHs) are promising bifunctional catalysts comprising tunable redox and Lewis acidic sites. However, most studies of LDH employ alkali hydroxide carbonate precipitants which may contaminate the final catalyst leach into reaction media. Here, we report an alkali-free route to prepare NixAl LDHs with a composition range x = 1.7 4.1 using (NH4)2CO3 NH4OH as precipit...

Electrostatic precipitators (ESP) and fabric filters (FF) are the main air pollution control equipment utilized to clean dust laden fumes from utility boilers. The choice among these systems depends on specific site conditions such as dust characteristics, required efficiency, gas flowrate and temperature. ESP are generally characterized by higher capital investments and lower operating charges...

BACKGROUND Observational studies have suggested that psychological stress increases the incidence of sudden cardiac death. Whether emotional or physical stressors can trigger spontaneous ventricular arrhythmias in patients at risk has not been systematically evaluated. METHODS AND RESULTS Patients with implantable cardioverter-defibrillators (ICDs) were given diaries to record levels of defin...

BACKGROUND Childhood constipation is a common problem, accounting for 3% of visits to pediatric clinics and 30% of visits to pediatric gastroenterologists. Estimates of the prevalence of childhood constipation vary from 0.3% to 28% with younger children being affected most often. We were unable to find any studies that specifically examine the causes of constipation in young children. Our objec...

Traditional theories regarding the etiology of borderline personality disorder have focused on poor attachment figures and/or traumatic experience. The present review posits an additional pathogenic course for this disorder. Specifically, the proposed mechanism involves a basic disruption of the neural hardware that supports the formation and maintenance of unconscious emotional memory, hardwar...
