Piezoelectric materials are substances that exhibit the piezoelectric effect, where mechanical stress applied to the material generates an electric charge, and conversely, applying an electric field can induce mechanical deformation. These materials are used in various applications, such as sensors, actuators, transducers, and even energy harvesting devices. Here’s a list of commonly used piezoelectric materials: ### Natural Piezoelectric Materials 1.

Rutilated quartz is a type of gemstone that features needle-like inclusions of rutile, a mineral composed primarily of titanium dioxide (TiO2). The rutile needles can appear in various colors, including gold, red, brown, and silver, and they can vary in thickness and arrangement, creating unique and striking patterns within the clear or translucent quartz.

Bottled gas refers to various types of gases that are stored under pressure in containers, typically cylinders or bottles. It is commonly used for a variety of applications, including heating, cooking, and fuel for vehicles. The most common types of bottled gas include: 1. **Liquefied Petroleum Gas (LPG)**: A mixture of propane and butane, LPG is widely used for home heating, cooking, and hot water systems. It is also used in certain vehicles as an alternative fuel.

Inelastic scattering is a process in which particles (such as photons, electrons, or neutrons) collide with a target and transfer some of their energy to the target during the interaction. This results in a change in the energy, momentum, or state of the incoming particles, as well as a change in the target particles.

Ocean color refers to the color of the ocean as perceived by the human eye, which results from the absorption and scattering of sunlight by water and various substances in the water. The color can vary widely depending on several factors, including: 1. **Water Depth**: In deep water, colors tend to appear darker and bluer, while shallow water may appear greener or brownish due to the presence of sediments and algae.

An ultramicroscope is a specialized optical microscope that is used to observe objects that are smaller than the wavelength of visible light. This allows for the visualization of colloidal particles, bacteria, and other minute structures that cannot be effectively resolved with conventional light microscopy. The ultramicroscope operates on the principle of dark-field microscopy, where light is directed at an angle to the specimen, and only scattered light is observed.

An emission spectrum is a spectrum of the electromagnetic radiation emitted by a substance that has absorbed energy. When atoms or molecules absorb energy, they can become excited and move to higher energy levels. When these electrons return to their original (or ground) state, they release energy in the form of light. The wavelengths of this emitted light correspond to specific energies and are characteristic of the particular element or compound.

Spike.

Nucleocapsid phosphoprotein, sticks to the RNA inside.

These are also required for test tube replication.

Does not appear to have any reverse IP hits unfortunately: opendata.stackexchange.com/questions/1951/dataset-of-domain-names/21077#21077. Likely only has domains that were explicitly advertised.

We could not find anything useful in it so far, but there is great potential to use this tool to find new IP ranges based on properties of existing IP ranges. Part of the problem is that the dataset is huge, and is split by top 256 bytes. But it would be reasonable to at least explore ranges with pre-existing known hits...

We have started looking for patterns on 66.* and 208.*, both selected as two relatively far away ranges that have a number of pre-existing hits. 208 should likely have been 212 considering later finds that put several ranges in 212.

tcpip_fp:

Protease that cuts up ORF1ab. Note that it is also present in ORF1ab.

The RdRp, since this is a Positive-strand RNA virus.

Unlike SARS-CoV-2 non-structural protein, these are not needed for test tube reproduction. They must therefore be for host modulation.

Integrates its RNA genome into the host genome.

Sounds complicated! The advantage is likely as in HIV: once inside the cell, it can remain hidden far away from the cell surface, but still infections.

E.g. in humans the adenine nucleotide translocator is present in chromosome 4, not in mtDNA.

These have almost certainly been transferred to nuclear DNA in the course of evolution.

This isn't completely surprising, since when mitochondria die, their DNA is kind of left in the cell, so it is not hard to imagine how genes end up getting uptaken by the nucleus. This is suggested at Power, Sex, Suicide by Nick Lane (2006) page 196.

A limiting factor appears to be that you can't just past those genes in the nucleus, further mutations are necessary for mitochondrial protein import to work, apparenty some kind of tagging with extra amino acids.

However, you likely don't want to remove all genes from the mitochondria because mitochondria have DNA because they need to be controlled individually.

Converts RNA to DNA, i.e. the inverse of transcription. Found in viruses such as Retrovirus, which includes e.g. HIV.
