Studies of oxygen-helium discharges for use in electric oxygen-iodine lasers
… electronically-excited molecular oxygen, O2(a). O2(a) serves as an energy reservoir in the laser system, pumping atomic iodine by near-resonant energy transfer producing gain and laser on the I(2P1/2) --> I(2P3/2) transition at 1315 nm. Initial experimental work with radio-frequency …

Influencia de la asimilación de nitrógeno y el estrés salino sobre la capacidad fotosintética en cebada
… estrés salino sobre el desprendimiento neto de o2, la fijación neta de co2 y la actividad fosfoenolpiruvatocarboxilasa. Los resultados obtenidos ponen de manifiesto que: 1) el suministro de nitrato, pero no de amonio, estimula el desprendimiento de o2 a co2 y luz saturantes, lo cual indica que …

Combined multispectral/hyperspectral remote sensing of tropospheric aerosols for quantification of their direct radiative effect
… of intensity and polarization in the O2 A-band and the 1.61- and 2.06-μm CO2 bands. It is found that the use of the hyperspectral bands provides a means to separate the effects of the surface and aerosol absorption from effects related to aerosol single scattering parameters. The …

Determining gas temperature from spectroscopic measurements in electric oxygen-iodine lasers
… temperature information was calculated using the O2(b1Σ) emission spectrum. This thesis discusses a new temperature diagnostic so that gas temperatures can be obtained from the O2(a1Δ) emission spectrum. Determining the temperature from O2(a1Δ) is accomplished by matching the experimental spectrum …

Electrochemical and Photocatalytic Flow Strategies for Sustainable Substrate Oxidation
… evolution reaction (OER) within a conventional CO2 reduction electrolyser, on account of the high energy penalty of the OER and the low commercial value of O2. A novel hybrid anode was fabricated, featuring a silatrane-modified TEMPO catalyst which was covalently immobilised on a mesoporous …

Reactive oxygen and nitrogen species production in cardiomyoblasts during hypoxia and reoxygenation
… in which tissues are deprived of an adequate O2 supply; this may trigger cell death with pathological consequences in cardiovascular or neurodegenerative disease. Reperfusion is the restoration of an oxygenated blood supply to hypoxic tissue and can cause more cell injury. The kinetics and …

Scientific principles for the electric oxygen-iodine laser
… 1970s. With low yields of the energy reservoir, O2(a), achievable in an electric discharge, EOIL research has for many years taken a lower priority when compared to the research of high-yield chemical oxygen-iodine lasers (COIL), which reported successes as early as 1978. While both lasers emit …

Transcriptional Regulation by Hypoxia-Inducible Factors in Tumor Cells
… of neuroblastoma cells. Hypoxia (1% O2) induced the expression of the negative transcription factor ID2 (Paper I), involved in blocking the function of tissue-specific basic helix-loop-helix (bHLH) proteins, such as the SNS-specifying transcription factors HASH-1 and dHAND. Hypoxic …
