Oxygen additions are a common practice in winemaking, as oxygen has a positive effect in fermentative kinetics, biomass synthesis and improvement of color, structure and :flavor in treated wines. However, most oxygen ...

An amperometric oxygen sensor based on a polymeric nickel-salen (salen = N,N '-ethylenebis(salicydeneiminato)) film coated platinum electrode was developed. The sensor was constructed by electropolymerization of nickel-salen ...

Oxygen mass transfer in aerobic microbial growth systems is often a limiting factor for optimal growth and productivity. Oxygen mass transfer has been widely studied in submerged fermentations but has attracted as yet ...

Ventilation of the eastern South Pacific Oxygen Minimum Zone (ESP-OMZ) is quantified using climatological Argo and dissolved oxygen data, combined with reanalysis wind stress data. We (1) estimate all oxygen fluxes (advection ...

In this work we have studied the electronic structure of finite polyacetylene chains with structural oxygen-bonding models following data from 13C-NMR experiments. We have used a combination of Austin Method One and ...

Here we show the design, preparation, and characterization of a dormant singlet oxygen (1O2) photosensitizer that is activated upon its reaction with reactive oxygen species (ROS), including 1O2 itself, in what constitutes ...

The relative influences of hypoxia and other environmental stressors on growth at alti-tude remain unclear. Previous work demonstrated an association between peripheral arterial oxygen saturation (SPO2)and anthropometry ...

Oxygen is fundamental to life. Not only is it essential for the survival of individual animals, but it regulates global cycles of major nutrients and carbon. The oxygen content of the open ocean and coastal waters has been ...

This study aimed at determining the effect of kappa number, lignin and hexenuronic acid contents on oxygen stage performance. Industrial brown pulps produced by the ITC and KobudoMARI cooking technologies, of kappa number ...
