Is there any cases algae not using the nutrient from the wastewater and grow normally?

I am working on microalgae cultivation using waste water. The initial concentration of nutrients were less but the microalgae has achieved biomass growth of 2 g/L. The final concentration of...

1. If I can quantize the atom using this hyperbolic spiral and classical physics, could nature do the same?

If we map as a continuous motion an ionising electron (beginning its journey at n=1) in an H atom, a specific hyperbolic spiral appears (see animation). When we solve this spiral formula, we find...

Why results of ROS flurescence are negative as there was no bacteria within?

Hello. I am working on ROS production of two systems: system A is cerium oxide and hydrogen peroxide, system B is cerium oxide nanoparticle, hydrogen peroxide and potassium bromide. I did some...

What should I do with parameters that are not relate to my simulation in MyLake model?

I want to Estimate surface heat fluxes using MyLake, but I don't have all the initial values in model parameters section and other sections,is there a way?

Why reactivity isn't increased with more empty spots in valence shell?

If from a geometric perspective the non-halogens, non-noble gases have more empty spots in their valence shell, and the filling/exiting of any of the empty spots in the shell constitutes a...

Why is the molecule's orientation with an electric field affect polarizability?

Why is the molecule's orientation with an electric field affect polarizability? Electrons are diffuse enough to be independent with respect to orientation and effect of electric field on...

Why don't d-orbitals split themselves, why does it take a ligand? why don't protons from ligand repel nucleus split d-orbitals?

why don't d-orbitals split themselves because of themselves without the presence of ligands? Electrons are indistinguishable. Why wouldn't it be more correct that protons from a ligand split the...

Why doesn't chromium 2+ ion use all its d-orbitals to receive lone pairs from six waters in [Cr(H20)6)]3+?

I'm guessing it's because the ligand experiences too much electron repulsion or proton repulsion from the chromium to insert them close to the 3d-orbitals which are close to the metal nucleus. Is...

How to confirm the site-directed mutagenesis result without performing NGS?

I'm cloning a fragment of 3200 nts into plasmid. The cloning was successful, however, 02 amino acids were mutated. Now I want to fix these 02 aa by site-directed mutagenesis technique using...

Self-Organizing Superorganisms—as envisaged by Nenad Sestan (2018)?

The rate of glucose consumption by the neocortex is reduced by over 80% during anesthesia (Sibson et al. 1998), which disables the synapses (Richards 2002) that are inundated by glial tissue (Engl...
