The effects of seagrass bed geometry on wave attenuation and suspended sediment transport were investigated using a modified Nearshore Community Model (NearCoM). The model was enhanced to account for cohesive sediment erosion and deposition, sediment transport, combined wave and current shear stresses, and seagrass effects on drag. Expressions for seagrass drag as a function of seagrass shoot d...

Annular flumes were used to quantlfy benthic-pelaqc exchanges in relation to changes in current velocity and sediment biota. Various physical, chemical and biological parameters were determined for 4 sites on the Molenplaat tidal flat in the Westerschelde (The Netherlands) during 2 field campaigns in May-June and August-September 1996. These Pcluded: the mass of sediment eroded, maximum and mea...

background: a great deal of evidence has indicated that oxidatively modified ldl plays a critical role in the initiation and progression of atherosclerosis. antioxidants that can prevent ldl oxidation may act as antiatherogens. copper is a candidate for oxidizing ldl in atherosclerotic lesions. the binding of copper ions to ldl is usually thought to be a prerequisite for ldl oxidation by copper...

introduction this paper proposes the concept of autonomous drug-encapsulated nanoparticle (adenp) as a novel non-invasive approach to prevent atherosclerosis. adenp consists of three simple units of sensor, controller (computing), and actuator. the hardware complexity of adenp is much lower than most of the nanorobots, while the performance is maintained by the synergism in the swarm architectu...

background: elevated serum levels of oxidized low-density lipoprotein (oxldl) have been found in type 2 and in poorly controlled diabetic patients. gestational diabetes mellitus (gdm) has common features with type 2 diabetes. objective: the aim of our study was to evaluate the serum levels of oxldl in women with gdm compared to normal pregnant women. materials and methods: in this cross-section...

barbari is a common iranian flat bread that has a short shelf life. the effect of low density polyethylene/clay nanocomposite film was investigated for the package and shelf life of the flat bread when stored at different temperatures and relative humilities with different percentages of nanoparticles. nanoclay concentrations of 2% and 6% were used for the nanocomposite and pure polyethylene wa...

Seismic reflection and refraction images illuminate the San Andreas Fault to a depth of 1 kilometer. The prestack depth-migrated reflection image contains near-vertical reflections aligned with the active fault trace. The fault is vertical in the upper 0.5 kilometer, then dips about 70 degrees to the southwest to at least 1 kilometer subsurface. This dip reconciles the difference between the co...

Nematodes are among the metazoans most tolerant of low-oxygen conditions and play major roles in seafloor ecosystem processes. Nematode communities were studied in sediments off Concepción, Central Chile, spanning the outer shelf within the OMZ (122 m) to the mid-lower continental slope (972 m) beneath the OMZ. The total density and biomass of nematodes (core depth 0–10 cm) ranged from 677 to 2...
