We have determined that an organism able to degrade both RDX and TNT in a pure culture is a strain ofClostridium bifermentans. The consortium from which this organism is derived also degrades these compounds, and we suspect thatC. bifermentans is also the responsible organism within that consortium. The bioconversion of RDX and TNT occurs under anaerobic(More)
TOPIC This article describes the components of child- and family-centered care, including a review of the literature about the delivery of family-centered care and the barriers that often prevent the provision of such care. The article describes an inpatient child psychiatric unit that has implemented an approach to care that embraces these principles. The(More)
The authors describe "collaborative problem solving," a cognitive-behavioral approach for working with aggressive children and adolescents. The model conceptualizes aggressive behavior as the byproduct of lagging cognitive skills in the domains of flexibility, frustration tolerance, and problem solving. The goal is to train staff to assess specific(More)
Temporal dynamics create unique and often ephemeral conditions that can influence soil microbial biogeography at different spatial scales. This study investigated the relation between decimeter to meter spatial variability of soil microbial community structure, plant diversity, and soil properties at six dates from April through November. We also explored(More)
Interrelated successive transformation steps of nitrification are performed by distinct microbial groups - the ammonia-oxidizers, comprising ammonia-oxidizing archaea (AOA) and bacteria (AOB), and nitrite-oxidizers such as Nitrobacter and Nitrospira, which are the dominant genera in the investigated soils. Hence, not only their presence and activity in the(More)
Characterization of spatial and temporal variation in grassland productivity and nutrition is crucial for a comprehensive understanding of ecosystem function. Although within-site heterogeneity in soil and plant properties has been shown to be relevant for plant community stability, spatiotemporal variability in these factors is still understudied in(More)
Two case studies are presented reflecting the ethical dilemmas experienced by nurses who were striving to improve their practice in the provision of patient care. The cases are described in the context of finding alternatives to cohesive interventions such as chemical restraints and physical restraints. A summary of the literature on ethical dilemmas that(More)
