Alternative primary treatment for energy-positive wastewater treatment: an exploration of pile cloth media filtration
… need for innovative research aimed at developing energy-neutral wastewater treatment paradigms. Improving primary treatment methods is one of the most urgent technological upgrades needed in wastewater treatment. The adaptation of pile cloth filtration (PCF) for primary treatment can enhance the …

Residual lattice defects in silicon(100) films doped with low-energy positive boron and positive arsenic ions during growth by molecular-beam epitaxy: Variation with ion energy and growth temperature
… grown at the highest temperature and lowest ion energy, and no majority-carrier traps were detected by DLTS. For B$\sp+$ ion doping, decreasing the growth temperature from 800$\sp\circ$C or increasing the ion energy from 100 eV caused a suppression in the intensity of sharp, B-BE PL peaks, with …

Hydrogen-Rich Syngas Derived from Smouldering Biomass and Hydrocarbon Wastes
… to new fuel sources to meet the surging global energy demand. Hydrogen has been proposed as a promising energy vector being both a net-zero carbon emitter and having one of the highest gravimetric energy densities of known fuels. Production of hydrogen, however, is difficult with many of the …

Be The Light: A Leader’s Vitality Fuels Extraordinary Results
… rise, many leaders struggle to sustain the energy needed to fulfill their full potential. This capstone, grounded in positive psychology and leadership science, makes the case that to lead others well, leaders must first nurture and protect their own vitality. Rather than focusing on burnout …

Elucidating the relative environmental sustainability of anaerobic membrane bioreactor (AnMBR) development pathways
… relies on aerobic- based technologies, which are energy-intensive and thus inconsistent with the trend in which broader environmental impacts are becoming increasingly important in decision-making. Anaerobic membrane bioreactors (AnMBRs), as an emerging anaerobic technology, are gaining popularity …

Advancing sustainable wastewater treatment: elucidating tradeoffs among emerging resource recovery technologies through quantitative sustainable design
… it provides a high-quality effluent, it is also energy intensive. High energy demand is costly both economically and environmentally. These problems underlie a need to re-envision WWTPs as a resource capable of nutrient and energy recovery while continuing to hold human and environmental health …

Stoichiometry and kinetic modeling of an anaerobic baffled reactor, The
… treatment of wastewater requires a substantial energy input, while effectively wasting a significant portion of the potential chemical energy found in the raw wastewater. This energy intensive process is perpetuated downstream of the aerobic treatment scheme due to its effectiveness in …

Scalogram analysis as a measure of dietary differentiation in relation to selected sociodemographic and health indicators among four ethnic groups residing in Jerusalem, Israel
… a significant negative association with age and positive association with education of father. Spouse status inconsistency was marginally positively associated with dietary complexity. Spouse scale scores were significantly correlated for homogeneous (same origin) pairs but not for nonhomogeneous …

Feeling Good, Being Green: The Emotional Drivers of Proenvironmental Action
… Emerging research suggests that anticipating positive emotions, such as pride, for performing proenvironmental actions may especially impact sustained and broader forms of environmental engagement, or the extent to which people persist in their behavior over time and take action in a variety …

Evaluation of anaerobic membrane bioreactors and hydrothermal catalytic gasification for enhanced conversion of organic wastes to renewable fuels
… treatment process that can effectively generate energy while removing particulates and organics in a single process. AnMBR studies with municipal wastewater have observed high COD removal rates typically in the range of 72 – 94%, and methane yields higher than can be achieved with conventional …
