I think the project might be called ‘How to be a duck’….

“To increase the surface area, the water has to be disturbed, it cannot be stagnant. Hence, ducks swimming in the water act as biological aerators as they help in creating disturbance in the water,”

“Bioturbation: The feeding activities of waterfowl, especially those that probe or peck at the substrate, can lead to bioturbation (disturbance of sediments). This can influence nutrient cycling, sediment structure, and the availability of resources for other organisms.

“Waterfowl can help control algae populations by feeding on them. This grazing behavior can influence the balance between different algal species and help prevent excessive algal blooms.”

The role of a duck to maintain algae blooms:

• Aeration
• Bioturbation
• Consumption/Removal

AERATION

using a milk bottle top + piezo sensor, and then the audio interface to compute the data

from this youtube video

This has helped me visualise a film:

• watch the video https://www.youtube.com/watch?v=CvxTogOS7zs
• use cad to design and 3D print
• impeller
• cyclone…..
• deployable mechanism
• kinetic, self sustainable moving creature
• also explore how to make undigestible algae digestible

tomorrow

• try print Omniball Wind Turbine in the day
• think about mandala toy and maybe make Circular Linkage using lolly pop sticks

I could try attach an impeller to stick, attach stick to a motor, power the motor with a battery, and control it with a speed controller (potentiometer) and a switch

• try this on paint-like algae and see what it’s effect is… could test it on lots of different types

eukaryotic―i.e., having cells like our own, with a membrane-bound nucleus, as opposed to prokaryotic-like bacteria. While some of these are disease-causing, the majority simply exist as part of the vast food web and have their own ecological niches and importance. Many are considered protozoans, meaning they have animal-like traits and were once thought to be the ancestors of modern animals. These tiny creatures are commonly studied in school and can often be seen swimming in a drop of water viewed through a microscope.

Algae are primarily eukaryotic photoautotrophic organisms which perform oxygenic photosynthesis

Photoautotrophs are organisms that use light energy and inorganic carbon to produce organic materials. Eukaryotic photoautotrophs absorb energy through the chlorophyll molecules in their chloroplasts while prokaryotic photoautotrophs use chlorophylls and bacteriochlorophylls present in free-floating thylakoids in their cytoplasm. All known photoautotrophs perform photosynthesis. Examples include plants, algae, and cyanobacteria.

Inorganic carbon is carbon extracted from ores and minerals, as opposed to organic carbon found in nature through plants and living things.

NOTES ON NITROGEN FIXATION

Nitrogen fixation is a process that implies the transformation of the relatively non-reactive atmospheric N2 into its more reactive compounds (nitrates, nitrites, or ammonia). Why is nitrogen fixation important? Such reactive forms are suitable for crops and support their growth. On the contrary, nitrogen deficiency stuns crop growth and healthy development. About 90% of natural N fixation on our planet is biotic and occurs thanks to soil microorganisms. Abiotic natural inducers are lightning and UV rays. Alternatively, N can be fixed with electrical equipment or industrially.

The dissolution of nitrogen dioxide (NO2) into water typically results in the formation of nitrite (NO2-) and nitrate (NO3-) ions. The exact ratio of nitrite to nitrate ions formed can depend on several factors, including the specific conditions of the reaction.

For the sake of simplification, let’s assume that all the NO2 dissolves into water and is completely converted to nitrate ions (NO3-). This is a simplification because in reality, a portion of it may also form nitrite ions.

Given that you have 250 micrograms per cubic meter (µg/m³) of NO2 in the atmosphere, you can calculate the total mass of NO2 in 100 ml of water as follows:

First, convert the volume of water to liters: 100 ml = 0.1 liters

Now, calculate the total mass of NO2 in 100 ml of water: (250 µg/m³) * (0.1 liters) = 25 µg

So, 25 micrograms of NO2 would be dissolved into 100 ml of water. If we assume that all of this NO2 is converted to nitrate (NO3-), then 25 micrograms of NO3- would be dissolved in the water. Please note that in reality, there might be a mixture of nitrite (NO2-) and nitrate ions depending on the specific conditions of the dissolution and subsequent reactions.

So, 12.5 micrograms of NO2 would be dissolved into 50 ml of water. If we assume that all of this NO2 is converted to nitrate (NO3-), then 12.5 micrograms of NO3- would be dissolved in the water. Again, please note that in reality, there might be a mixture of nitrite (NO2-) and nitrate ions depending on the specific conditions of the dissolution and subsequent reactions.

Plants are able to sense and respond to a myriad of external stimuli, using different signal transduction pathways, including electrical signaling. The ability to monitor plant responses is essential not only for fundamental plant science, but also to gain knowledge on how to interface plants with technology. Still, the field of plant electrophysiology remains rather unexplored when compared to its animal counterpart. Indeed, most studies continue to rely on invasive techniques or on bulky inorganic electrodes that oftentimes are not ideal for stable integration with plant tissues. On the other hand, few studies have proposed novel approaches to monitor plant signals, based on non-invasive conformable electrodes or even organic transistors. Organic electrochemical transistors (OECTs) are particularly promising for electrophysiology as they are inherently amplification devices, they operate at low voltages, can be miniaturized, and be fabricated in flexible and conformable substrates. Thus, in this study, we characterize OECTs as viable tools to measure plant electrical signals, comparing them to the performance of the current standard, Ag/AgCl electrodes. For that, we focused on two widely studied plant signals: the Venus flytrap (VFT) action potentials elicited by mechanical stimulation of its sensitive trigger hairs, and the wound response of Arabidopsis thaliana. We found that OECTs are able to record these signals without distortion and with the same resolution as Ag/AgCl electrodes and that they offer a major advantage in terms of signal noise, which allow them to be used in field conditions. This work establishes these organic bioelectronic devices as non-invasive tools to monitor plant signaling that can provide insight into plant processes in their natural environment.
