Sediment deprivation from dam installments contributes to beach erosion yet the underlying physical and economic factors linking them together have traditionally been isolated during regional planning. In order to gain a better understanding of the behavior of a managed beach system, a dynamic simulation model was developed incorporating physical and monetary factors influencing the amount of a...

Sandstorm has an effect on the electric field characteristics of outdoor insulator, and may result in flashover. The analysis of the electric field characteristic of insulator under sandstorm condition is very important. The electrostatic field finite element method (FEM) is used to calculate the electric field distribution along long rod insulator under sandstorm condition with FEM software. T...

Results of a new analysis of the K+K− photoproduction at two photon energies Eγ = 4 GeV and 5.65 GeV with a particular emphasis on the S-wave production are presented. We show that the proper treatment of all the helicity components of the Sand P -waves enables one to eliminate the reported discrepancies in the extraction of the Swave photoproduction cross section from experimental data.

As a water quality purification measure for areas such as lakes, a sand capping method by sand-upwelling system was developed. This method involves welling up clean sand from below contaminated sludge by using a water jet. The disposal of sludge and the acquirement of pure sand are not necessary like dredging and conventional sand capping works. Besides, the ecosystem will hardly be disturbed b...

Manufactured sand differs from natural sea and river dredged sand in its physical and mineralogical properties. These can be both beneficial and detrimental to the fresh and hardened properties of concrete. This paper presents the results of a laboratory study in which manufactured sand produced in an industry sized crushing plant was characterised with respect to its physical and mineralogical...

BACKGROUND Ingestion of sand can cause colic, diarrhoea and weight loss in horses, but these signs are unspecific and can have many other causes. The amount of sand that induces disease may vary between individuals. To avoid over-diagnosing, it is important to determine the amount of sand that can be found in horses without clinical signs of gastrointestinal disease. The aim of this study was t...

Field-collected 4th-instar Glyptotendipes paripes larvae from a natural lake in central Florida preferred small-sized (< 0.84-1.99-mm-diam) grains of sand to burrow in and make cases in the laboratory. The larvae buried or formed cases within 3 h of introduction into 120-ml paper cups containing 80 ml tap water and 20 g of the small-diameter sand. When placed in sand with grains of different si...

The work aimed to study all the possible factors affecting efficiency of plant propagation via stem cuttings. Several factors including type of cutting, culture medium, type and concentration of growth regulators were investigated. These factors were studied on Ficus hawaii as woody tree and Chrysanthemum morifolium as herbaceous plant to investigate the effect of plant type factor. All experim...
