Temperature Dependence of Delayed
نویسنده
چکیده
The temperature dependence of delayed millisecond fluorescence (DF) induction curve transients was investigated. The transients were obtained by keep ing intact maize leaf segments in the dark for 30 to 300 s before illumination. The temperature dependence of DF induction revealed abrupt changes in activation energy of the recombination process. Those changes highly overcome the lowest en ergy barriers for certain types of chemical reactions, implying significant possible alterations in the DF mechanism itself. On the other hand, the particular transients responses expressed some specifities. Both the electrochemical gradient controlled changes, and the temperature induced changes contibute to it.

Measuring the temperature dependence of refractive index in water phantom for precise monitoring of the absorbed dose by radiation therapy techniques
In this paper, an experimental setup is used to measure the temperature dependence of the refractive index of a water phantom. In radiation calorimetry by laser beams and interferometric systems, the amount of change induced by radiation within the phantom can be accurately measured. Absorption of dose and the resulted change in temperature changes the refractive index within the material. In o...
متن کاملVariation in stability of elk and red deer populations with abiotic and biotic factors at the species-distribution scale.
Stability in population dynamics is an emergent property of the interaction between direct and delayed density dependence, the strengths of which vary with environmental covariates. Analysis of variation across populations in the strength of direct and delayed density dependence can reveal variation in stability properties of populations at the species level. We examined the stability propertie...

Room temperature phosphorescence emission of erythrosin B in sol±gel silica is studied over the oxygen pressure range from 10ÿ6 to 1000 mbar. Quenching by oxygen is signi®cant over the entire range. The Stern±Volmer (SV) intensity data can be very well ®tted using the two-site model. The temperature dependence of the phosphorescence and the delayed ̄uorescence are examined from ÿ173 to 2008C at...
متن کاملMeasurement and comparison of the temperature-dependence of refractive index of water and Plexiglas phantoms by interferometry method for their use in optical calorimetry
In radiation calorimetry by using laser beams and interferometry setups, variations induced by dose absorption in phantom can be precisely measured. Dose absorption and the induced temperature change result in refractive index variation of the material. In order to be able to measure the low amount of absorbed dose in the phantom, temperature dependence of refractive index of the material must ...
متن کاملPrediction of the Products Yield of Delayed Coking for Iranian Vacuum Residues
In this work, new correlations are proposed to predict the products yield of delayed coking as a function of CCR and temperature based on the experimental results. For this purpose, selected Iranian vacuum residues with Conradson carbon residue (CCR) values between 13.40-22.19 wt.% were heated at a 10 °C/min heating rate and thermally cracked in a temperature range of 400-500 °C in a laboratory...
