Several methods have been used to obtain complete MR images from a reduced set of measured encodes 1,2,3,4,5,6. All of these techniques use some sort of a priori information to complete the incomplete data set. These techniques have had varying degrees of success in a variety of applications: imaging contrast uptake, interventional procedures, spectroscopy, fMRI contrast changes, and routine sc...

I conducted an experiment to assess the effects of aeration on the growth of bullfrog tadpoles (Rana catesbeiana). Tadpoles in the non-aerated treatment grew slower than tadpoles in the aerated treatment. Tadpoles in the nonaerated treatment were observed at the water's surface more often and on food resources less often than tadpoles in the aerated treatment. Oxygen concentrations in natural a...

The present study addresses the effects of oxygen exposure on the aerobic and anaerobic respiratory activity of Desulfovibrio desulfuricans strain DvO1. This strain was isolated from the highest sulfate-reduction positive most-probable-number dilution (10(6)) of an activated sludge sample, which had been subjected to 120 h of continuous aeration. Washed cell suspensions of strain DvO1 were aera...

The principal objective of our study was to optimise a municipal activated sludge wastewater treatment plant (WWTP) to face high organic flows due to viticulture effluents inputs. Treatment file optimization consisted in testing different treatment lines, changing the number and volume of biological basins and clarifiers, with or without a buffer basin upstream, with a view to achieving a bette...

A systematic study into the effects of metal substitution on the visible-light photocatalytic activity of prototype metal oxide cluster anions is presented. Four isostructural Lindqvist clusters [V(x)M(6-x)O19]((2+x)-) (M = W, Mo, x = 1, 2) with photooxidative activity in the visible range are reported. It is shown that the photooxidative performance correlates with the number of vanadium atoms...

Conventional irrigation methods decrease greenhouse soil aeration, which leads to restricted root growth and reduced fungal abundance in grapes. In this study, aerated equipment was used investigate the effects of on biomass accumulation, growth, community structure grape seedlings. The results show that significantly increased length, surface area, volume, number tips by 38.5%, 32.1%, 62.1%, 2...

Submerged attached growth bioreactors (SAGBs) were operated at 20 °C for 30 weeks in smart-aerated, partial nitritation ANAMMOX mode and in a timer-controlled, cyclic aeration mode. The smart-aerated SAGBs removed 48-53% of total nitrogen (TN) compared to 45% for SAGBs with timed aeration. Low dissolved oxygen concentrations and cyclic pH patterns in the smart-aerated SAGBs suggested conditions...
