Development of sand ripples from a flat sand bed subjected to shallow water wave action is explained in terms of the unsteady kinematics of the sand particles that form the sand ripple. The steady kinematic requirements for a fully developed sand ripple are also specified, and are shown to be consistent with an idealized solution of the fluid velocity field near the sand bed. This idealized velocity field is a result of the interaction between the surface wave velocity field and the sand ripple shape. The velocity field is related to the sand transport rate by using an adaptation of Bagnold's transport equation for steady flow. Expressions are derived that define the maximum ripple height and wavelength in terms of the wave orbital velocity and sediment characteristics. Theoretical estimates are made of the vortex strength shed from the ripple crest and the role of this crest vortex is considered. Keywords: Sedimentation, sediment transport, waves, ripples, coastal engineering, hydrodynamics.

AbstractRecent prevalence estimates for autism have been alarming as a function of the notable increase. Speech-language pathologists play a critical role in screening, assessment and intervention for children with autism. This article reviews signs that may be indicative of autism at different stages of language development, and discusses the importance of several psychometric properties—sensitivity and specificity—in utilizing screening measures for children with autism. Critical components of assessment for children with autism are reviewed. This article concludes with examples of intervention targets for children with ASD at various levels of language development.

Cardiac registries have filled many gaps in knowledge related to arrhythmogenic cardiovascular conditions. Despite the less robust level of evidence available in registries when compared with clinical trials, registries have contributed a range of clinically useful information. In this review, the authors discuss the role that registries have played – related to diagnosis, natural history, risk stratification, treatment, and genetics of arrhythmogenic cardiovascular conditions – in closing knowledge gaps, and their role in the future.
