Nonlinear dynamics of upward propagating flames.

We study the influence of gravity on the dynamics of upward propagating premixed flames. We show that the role of gravity on the dispersion relation is small, but that the nonlinear effects are large. Using a Michelson Sivashinsky equation modified with a gravity term, it can be observed that the nonlinear dynamics of the crests is greatly influenced by gravity, as well as the final amplitude of the flame.

Sociodemographic and behavioural determinants of early childhood caries knowledge among expectant mothers in Kuwait.

Purpose: Early Childhood Caries (ECC) is a highly prevalent disease in Kuwait. It poses health, economic, and social implications affecting patients, their families and communities. ECC awareness campaigns targeting expectant mothers hold a promising potential as primary prevention tools.

Microshear bond strength of different restorative materials to teeth with molar-incisor-hypomineralisation (MIH): a pilot study.

Aim: To compare the microshear bond strength of resin based composite (RBC) and resin modified glass ionomer cement (RMGIC) restorations when bonded to teeth with molar incisor hypomineralisation (MIH).

Methods: Eleven first permanent molars with MIH were included in this study. Teeth were sectioned mesio-distally producing a total of 22 surfaces for testing.
