Laboratory experiments of dilute mixtures of warm talc powder in air simulate dilute pyroclastic density currents (PDCs) and show the effects of topography on current runout, buoyancy reversal, and liftoff into buoyant plumes. The densimetric and thermal Richardson, Froude, Stokes, and settling numbers for our experiments match those of natural PDCs. The laboratory currents are fully turbulent,...

Genomic imprinting is an epigenetic phenomenon causing parent-of-origin specific differential expression of maternally and paternally inherited alleles. While many imprinted genes have been identified in plants, the functional roles of most of them are unknown. In this study, we systematically examine the functional requirement of paternally expressed imprinted genes (PEGs) during seed developm...

To examine how inclusive our schools are after 25 years of educational reform, students with disabilities and their parents were asked to identify current barriers and provide suggestions for removing those barriers. Based on a series of focus group meetings, 15 students with mobility limitations (9-15 years) and 12 parents identified four categories of barriers at their schools: (a) the physic...

background women as active health information seekers play a key role in determining lifestyle and possible implementation of preventive measures, thereby improving the health of individuals, families and society. although studies indicate that equipping people with adequate health information leads to optimal health outcomes, sometimes the complexity of human behavior and presence of barriers ...

Objective The aim of this paper is to highlight the importance of the concept of perceived barriers in health promotion for risk factor reduction, and to describe a ‘Perceived barriers and lifestyle risk factor modification model’ which could potentially be incorporated into existing frameworks for diabetes education to enhance lifestyle risk factor education in women with type 2 diabetes. Sett...
