In general, we divided our system design into three major components:
Video processing, which tracks the current position of drum stick in real time;
Audio processing, which detects the ‘hit’ of the drum stick and generates drum sounds;
Integration of the previous 2 parts.
Required materials
There are some required materials for our system setup:
A webcam: a camera is used to videotape the paper and stick movements. In our experiment we simply used the webcam embedded in our laptop. However, other users may use any other types of cameras depending on individual requirements.
A microphone: since the camera can only track the stick's position but not being able to know whether the stick really hits the paper to make sound, a microphone is used to detect when the stick actually hits the paper (when the player wants to play a note). We placed the microphone inside a sound-prove paper box to avoid noise interference.
Our whole system works under the sequence numbered(from 1 to 4) in the above illustration.
Bacteria doesn't produce energy they are dependent upon their substrate in case of lack of nutrients they are able to make spores which helps them to sustain in harsh environments

But not all bacteria make spores, l mean Eukaryotic cells have Mitochondria which acts as powerhouse for them, since bacteria don't have it, what is the substitution for it?
Assimilatory nitrate reduction is a process that occurs in some microorganisms, such as bacteria and archaea, in which nitrate (NO3-) is reduced to nitrite (NO2-), and then further reduced to ammonia (NH3).
Elkana
This process is called assimilatory nitrate reduction because the nitrogen that is produced is incorporated in the cells of microorganisms where it can be used in the synthesis of amino acids and other nitrogen products
There are nothing like emergency disease but there are some common medical emergency which can occur simultaneously like Bleeding,heart attack,Breathing difficulties,severe pain heart stock.Hope you will get my point .Have a nice day ❣️

define infection ,prevention and control
Innocent
I think infection prevention and control is the avoidance of all things we do that gives out break of infections and promotion of health practices that promote life
