Circumventing kinetics in biogeochemical modeling

Modeling Biogeochemical Processes in Marine Ecosystems

Ecosystems are dynamic systems and the study of their functioning and evolution requires the development of dynamic biogeochemical models. A wide application and a pronounced development of this type of model has taken place during the last two decades due essentially, to the development of computer technology, which has permitted the handling of very complex mathematical systems, and also to t...

Major challenges confronting marine biogeochemical modeling

Substantial improvements are required in the current suite of numerical models if we are to better understand the present ocean biogeochemical state and predict potential future responses to anthropogenic perturbations. At present, major impediments to marine biogeochemical modeling include the inadequate representation of multi-element cycling and community structure, large-scale physical circ...

Modeling Chemical Kinetics Graphically

In literature on chemistry education it has often been suggested that students, at high school level and beyond, can benefit in their studies of chemical kinetics from computer supported activities. Use of system dynamics modeling software is one of the suggested quantitative approaches that could help to develop students’ knowledge about chemical kinetics and chemical equilibrium and to remedi...

Circumventing burnout in AIDS care.

Previous studies have determined that health care providers who specialize in AIDS care are particularly susceptible to work-related stress and resulting burnout. This qualitative study derived themes from interviews with three occupational therapists in order to examine these findings. Ultimately, stress and burnout were not dominant themes in the interviews. Instead, the prominent themes were...
