Aeration effects on impact have been investigated by dropping a flat plate onto the water surface, in which the water is aerated to various degrees. An experimental study has been carried out in the newly commissioned Ocean Basin at Plymouth University’s COAST Lab. The falling block comprises a rigid impact plate connected to two driver plates and its total mass can be varied between 32 kg and ...
Lagoons are habitat islands in the coastal landscapes characterised by both among ecosystems 1 heterogeneity, due to different terrestrial-freshwater, freshwater-marine interfaces, and within ecosystem heterogeneity, due patchy spatial and temporal distribution of biotic and abiotic
Temporal coherence (i.e., the degree of synchronicity of a given variable among ecological units within a predefined space) has been shown for several limnological features among temperate lakes, allowing predictions about the structure and function of ecosystems. However, there is little evidence of temporal coherence among tropical aquatic systems, where the climatic variability among seasons...
The composition of the passive layers formed on Zn electrode in naturally aerated and de-aerated 0.1 M KClO4 solution were studied using X-ray hotoelectron spectroscopic measurements (XPS). A correlation between the presence of dissolved O2 and the formation of an interior passive ayer was carried out. Librated Cl− from the perchlorate reduction reaction was detected in its solutions during Zn ...
conducted in the 1980s, is estimated to run to £15 billion. The UK government's Sustainable Development Commission (SDC) estimates that this facility could save 5.6 Mt carbon dioxide per year, in comparison to new-built gas-fired power plants. The carbon footprint of building the barrage would be paid back in 5–8 months, according to the SDC. The concept is based on proven technology, as a simi...
RATIONALE Tidal volume and plateau pressure limitation decreases mortality in acute respiratory distress syndrome. Computed tomography demonstrated a small, normally aerated compartment on the top of poorly aerated and nonaerated compartments that may be hyperinflated by tidal inflation. OBJECTIVES We hypothesized that despite tidal volume and plateau pressure limitation, patients with a larg...
INTRODUCTION Previous randomized trials failed to demonstrate a decrease in mortality of patients with acute lung injury treated by exogenous surfactant. The aim of this prospective randomized study was to evaluate the effects of exogenous porcine-derived surfactant on pulmonary reaeration and lung tissue in patients with acute lung injury and acute respiratory distress syndrome (ALI/ARDS). M...
