Oxygen management during alcoholic fermentatión
(2015)
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 ...
Reassessment of the estimation of dissolved oxygen concentration profile and K(L)a in solid-state fermentation
(ELSEVIER SCI LTD, 2000)
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 ...
Associations between arterial oxygen saturation, body size and limb measurements among high-altitude andean children
(Wiley, 2013)
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 ...
Influence of oxygen flow on crystallization and morphology of LiNbO 3 thin films
(2002-01-01)
Polymeric precursor solution (Pechini method) was used to deposit LiNbO 3 thin films by spin-coating on (100) silicon substrates. X-ray diffraction data of thin films showed that the increase of oxygen flow promotes a ...

Cattle in vitro induced pluripotent stem cells generated and maintained in 5 or 20% oxygen and different supplementation
(2021-06-01)
The event of cellular reprogramming into pluripotency is influenced by several factors, such as in vitro culture conditions (e.g., culture medium and oxygen concentration). Herein, bovine iPSCs (biPSCs) were generated in ...
Oxygen diffusion in superconducting oxides
(Trans Tech Publications Ltd, 2008-01-01)
Since the discovery of high-temperature superconductivity of cuprate oxides, it has been clear that it is strongly affected by the oxygen content, which is also a crucial factor to determine other physical properties of ...

The Influence of Small Quantities of Oxygen in the Structure, Microstructure, Hardness, Elasticity Modulus and Cytocompatibility of Ti-Zr Alloys for Dental Applications
(Mdpi Ag, 2014-01-01)
The mechanical properties of Ti alloys are changed significantly with the addition of interstitial elements, such as oxygen. Because oxygen is a strong stabilizer of the a phase and has an effect on hardening in a solid ...
Modeling the influence of benthic primary production on oxygen transport through the water-sediment interface
(Elsevier, 2015)
The context of this study is salty lagoons a few centimeters deep that are found in the arid region of the Andes Mountains in South America. The trophic structure of these aquatic ecosystems is supported by microalgae and ...
