HOW ARE BEACHES SUPPLIED WITH SHINGLE?

Life expectancy of shingle beaches: measuring in situ abrasion

In situ abrasion of shingle beach material is a neglected area of study in coastal geomorphology, with reduction in beach volumes normally attributed to longshore and offshore drift. Results from field abrasion experiments conducted on flint shingle beaches on the East Sussex coast, southern England, show that in situ reductions in volume of beach material may be more significant than has been ...

Estimation of Abrasion Loss on Flint Shingle Beaches in East Sussex, Uk

The results are described of ongoing field and laboratory experiments to estimate losses from shingle beaches due to abrasion. Field abrasion experiments of two exotic lithologies (quartzite and limestone) used as tracers on two flint shingle beaches at Telscombe and Saltdean in East Sussex, UK, have been carried out over 23 months, resulting in 985 weight loss measurements. Relationships betwe...

Pnm-19: How Are Prenatal Screening Results after ART Success?

Background Down syndrome screening at first-trimester may cause a higher false positive rate in pregnant patients who have undergone assisted reproductive technologies (ART). Combining the second largest series of biophysical and biochemical tests in the first trimester of pregnancy after ART is mentioned in few studies. MaterialsAndMethods Ghisoni et al explored that NT measurement between ART...

How are postural strategies modified along the time?

Postural control is critical for effective performance of all goal-directed activities. For maintenance of postural equilibrium against gravity and environmental disturbances, central nervous system produces centrally organized patterns of muscle activity based on initial conditions, perturbation characteristics, learning and intention. These organized strategies are called "postural strategies...
