Although large loads of potentially toxic constituents are discharged from coastal urban watersheds, very little is known about the fates and eventual impacts of these stormwater inputs once they enter the ocean. The goal of this study was to examine the effects of stormwater discharges on the benthic marine environment of Santa Monica Bay. Sediment samples were collected across a gradient of s...

The objective of this investigation was assessment of physical and chemical parameters ofsoil and sediment in loess lands under different land uses, in the north of Iran. A yearly soilsampling was carried out randomly in three land uses (cultivated, forest and pasture) inQarnave and Yelcheshme watersheds. Sediment samples were taken monthly in thewatersheds at the hydrometrical station of Tamer...

among different spd techniques, equal channel angular pressing has attracted the most attentions,because of applying large strain to solid bulk materials. in this research, ecap process up to 6passes was carried out on a pure copper and a 6012 al-mg-si alloy with bc route in ecap dieswith φ=120 and ψ=20 and diameter of 20and 10 millimeter respectively. moreover, x-raydiffraction (xrd) system wa...

Abst rac t -Previous work (b.~ us and others) has shown that sediment trap fluxes do not correlate well with the total particulate mass concentration as determined with a t ransmlssometer Sediment traps are thought to collect the settling particles in the marine snow size range (d > 0 5 mm) Cameras ha,~e been developed to quantitatively image particles in the marine snow size range but a correl...

This paper deals with the packing of square tiles of the same size into one texture. Texture size is constrained by the graphics hardware. In particular, width and height resolutions must be powers of two. To cover the whole texture and avoid space loss, common schemes pack a number of tiles that is a power of two. We show that numbers of tiles like 5, 13, 17, 25, 34 and others can also be reac...
