The photosensitized production of singlet oxygen is a benchmark reaction for characterizing flow photoreactors. Light absorption the driving force photooxidation and modelling represents fast cost-efficient method its prediction optimization. In this study, we report two models photon in single- two-phase flow. Firstly, three-dimensional ray tracing model was developed validated by experimental...

Carbon tetrafluoride (CF4), also known as tetrafluoromethane and sometimes CFC-14, has a natural lithospheric source, however the enhanced modern-day concentrations relative to this source have arisen from leaks into atmosphere by industry, most significantly related production of aluminium semiconductors. A potent greenhouse gas, with one longest atmospheric lifetimes 50,000 years, abundance c...

Leaf hydraulic conductance (KLeaf) is a measure of the efficiency water transport through leaf, which determines physiological parameters such as stomatal conductance, photosynthesis and transpiration rates. One key anatomical structure that supports KLeaf leaf venation, could be subject to evolutionary pressure in dry environments. In this context, it useful assess these traits species from ar...

Inflammaging is a theory which purports that chronic inflammation leads to cellular dysfunction and premature aging of tissue. Skin susceptible inflammaging because it the first line defense from environment can be heightened in photoexposed skin. To better understand impact photoexposure on epidermal biology we performed systems biology-based analysis protected sites women between ages 20’s 70...

The broad objectives of this work are the testing, deployment and refinement of spectroscopic sensors for monitoring the distributions of reactive chemicals in seawater. The analytes of special interest in this work are iron, copper, nitrate, nitrite, ammonia, phosphate and CO2-system variables (total inorganic carbon, total alkalinity, CO2 partial pressure and pH). The desired accuracy of the ...
