Coupling the PLANKTOM5.0 marine ecosystem model to the OCCAM 1º ocean general circulation model for investigation of the sensitivity of global biogeochemical cycles to variations in ecosystem complexity and physical environment [PDF]
, 2008 The earliest marine ecosystem models consisted of a simple representation of the main features of marine ecosystems, including, typically, variables for phytoplankton, zooplankton, nutrient and detritus (NPZD models).

An in vitro assessment using transverse microradiography of the effect on mineral loss of etching enamel for in situ studies. [PDF]
, 2003 OBJECTIVES: To test the hypothesis that etching enamel with 37% phosphoric acid for 30 s does not lead to detectable mineral loss when measured with transverse microradiography (TMR). DESIGN: An in vitro laboratory investigation.

European Journal of Oral Sciences, EarlyView.Abstract This study evaluated salivary fluoride (F) bioavailability during diurnal and nocturnal periods after using a high‐fluoride or regular dentifrice. Fifteen healthy adults participated in a double‐blind crossover study, brushing with either a 1450 ppm F or 5000 ppm F dentifrice.

European Journal of Oral Sciences, EarlyView.Abstract Calcium silicate‐based and glass ionomer cements are often used in caries‐affected dentine. This study investigated the remineralising and physicochemical properties of two calcium silicates and a glass ionomer cement. Human molars with Class I cavities were subjected to pH cycling to simulate caries lesions.

Gerodontology, EarlyView.ABSTRACT Background Dental caries remains highly prevalent in older adults and represents a growing public health concern due to increased tooth retention, polypharmacy, hyposalivation and functional limitations. Silver diamine fluoride (SDF) is widely used for caries arrest in this population but causes undesirable tooth staining. Nano Silver Fluoride
