In freshwater environments, salinity is a significant environmental stressor that has an impact on aquatic plant development and survival. Elevated salinity levels, frequently originating from natural processes or human actions, can lead to diminished plant growth, poor photosynthesis, and even plant mortality. Hence, the study tried to analyze the...
Monthly 24-h real-time high-resolution monitoring was conducted for 1 year to investigate the carbon dioxide (CO2) dynamics in the lower Brahmaputra River. The partial pressure of CO2 (pCO2) was observed between 136 and 1213 µatm. The pCO2 was almost 1.5 times higher during the wet season (May–October) than during the dry season (November–April). D...
Glaciers play key roles in capturing, storing, and transforming global carbon and nitrogen, thereby contributing markedly to their cycles. However, an integrated mechanistic approach is still lacking regarding glacier's primary producers (PP), in terms of stable dissolved inorganic carbon isotope (δ13C-DIC) and its relationship with dissolved carbo...

Questions
Questions (5)
Is it possible to identify concentration of unknown organic component from excel data using MATLAB? If it can, what is the process or method?
I have used Excel data (From Serial diluted solutions) in PARAFAC to build model. But is there any way to determine concentration from these excel data in MATLAB?
I'm working with algal organic matter (molecular weight unknown) to titrate with different ligands. How can I fit them into the model when I don't know their molecular weight. So I can't put any values to mM. Please suggest.
After physical extraction of EPS from the biofilm, which Fluorescent dyes I can use for staining EPS protein and polysaccharide to observe in confocal laser scanning microscopy? As I've checked some references, FITC is bio-compatibe with protein, but am not sure which one to use for polysaccharide staining.
Is Calcoflour white (M2R) biocompatible for polysaccharide staining in case of extracted EPS?
Thank you all in advance!
Hi, all! Can anyone suggest how to measure Transparent exopolymeric particle (TEP) concentration in fresh water sample? What are the spectroscopic techniques I can employ for detail measuring?
I'm working with a quantam meter that gives PAR (photo active radiation) value of micro mole/M2/s. I'm using this for measuring sunlight PAR. Is there anyway I can covert this to W/m2? I've seen some approximate conversion like 1800 micro mole/M2/s equals 427 W/m2. In another lecture its 2200 micro mole/M2/S equals to 500 W/m2. Can anyone provide references?
