2016b). We used a biogeochemical ocean model to estimate the mean chlorophyll a concentrations, net primary production (NPP) vertically integrated from the surface to the seafloor, as well as the ...

Under drought stress, chlorophyll content and photosynthetic parameters significantly decreased ... with the concentration calculated from the absorption value at 450 nm wavelength using an enzyme ...

Iron is mainly absorbed in the first part of the small intestine, called the duodenum, which resides next to the stomach. Compounds in certain foods you eat can bind to iron and prevent absorption, ...

Sub-wavelength optics is the study of light on a spatial scale smaller than its wavelength. Conventionally, the minimum length scale on which a beam of light can operate is equal to half its ...

Abstract: Elevated temperature can impact the accuracy of pulsed-laser (PL) SEE testing primarily due to the temperature dependence of optical absorption. This is particularly true for laser ...

Nutrients such as nitrogen and phosphorous are not directly measurable with satellite observations. However, satellites can measure chlorophyll concentration, which can act as somewhat of a proxy for ...

In the present study, oxygen concentrations up to ∼50 mM were used, resulting in a more accurate determination of the static quenching constant. Absorption spectra obtained at higher oxygen ...

What sets the Luma One Mask apart from other skincare gadgets is its scientific approach, utilizing different wavelengths of light to specifically target various ... As the Luma One Mask promotes ...
