Paper disc diffusion method is used to see what antibiotics or compounds inhibit bacterial growth, or are bacteriostatic. The paper discs are soaked with a select antibiotic or chemical and then placed on a lawn of bacteria in a petri dish. The zones of inhibition are measured around where the disc was placed to determine whether the bacteria was resistant or susceptible to the particular antibiotic or chemical chosen.

What method is used to test the effectiveness of 2 different antibiotics?
One common method is the disc diffusion assay, where paper discs saturated with each antibiotic are placed on a bacterial lawn, and the size of the resulting inhibition zone is measured. Another method is the broth microdilution assay, where different concentrations of each antibiotic are tested in liquid culture to determine the minimum inhibitory concentration (MIC) required to stop bacterial growth.
Why is the bad conductor preferred in the shape of a disc in lees disc method?
A bad conductor in the shape of a disc is preferred in Lee's disc method for thermal conductivity measurements because the disc shape ensures uniform heat flow in all directions, simplifying calculations. Additionally, the disc shape allows for easy measurement of the temperature difference across its diameter, which is crucial for determining thermal conductivity accurately.
What is the access method for optical discs?
The access method for optical discs is typically sequential, where data is read or written in a linear fashion from the outer edge of the disc to the center. This is in contrast to random access methods used in storage devices like hard drives, where data can be accessed in any order.
Which are used for cutting paper?
I generally use an angle grinder with a thin steel cutting disc. Sometimes I use a hacksaw, but my small angle grinder is pretty versatile and saves a lot of time.
What does it mean when a DVD player shows 'No disc' sign?
When a DVD player displays the "No disc" message, it typically indicates that the player is unable to read a disc that has been inserted. This could be due to a dirty or scratched disc, a compatibility issue, or a problem with the player's laser lens. Cleaning the disc and checking for any physical damage may help resolve the issue.
What is Disc diffusion method used in antibacterial activity?
In disc diffusion method, special papers like filter papers are cut into little disc-like shapes, dipped into the extract/s to be tested or antimicrobials using sterile forceps which then put on to the cultured microbes to be tested.

How do you find viscosity of given liquid by oscillating disc method?
To find the viscosity of a liquid using the oscillating disc method, you would typically place a disc in the liquid and oscillate it at a constant frequency. By measuring the torque required to keep the disc oscillating, along with other parameters like disc radius and frequency, you can calculate the viscosity using the equation specific to this method. This method is suitable for measuring the viscosity of Newtonian liquids.
Why is the bad conductor preferred in the shape of a disc in lees disc method?

How is the Minimal Inhibitory Concentration of an antibiotic determined?
The Minimal Inhibitory Concentration (MIC) of an antibiotic is determined through laboratory testing, typically using a broth dilution or agar diffusion method. In the broth dilution method, serial dilutions of the antibiotic are prepared in a growth medium, and a standardized inoculum of bacteria is added to each dilution. The MIC is the lowest concentration of the antibiotic that prevents visible growth of the bacteria after incubation. In the agar diffusion method, the antibiotic is applied to an agar plate inoculated with the bacteria, and the MIC is inferred from the size of the inhibition zone around the antibiotic disc.
What is the best method for compact disc duplication?
The best method to compact disc duplication is to use a machine such as SATA DVD Duplicator. This machine can duplicate both CD's and DVD's and has self diagnostics with power start.
What is Meyer's oscillating disc method?
Meyer's oscillating disc method is a technique used to determine the molecular weight of a polymer by measuring the change in weight of a solution containing the polymer as it oscillates at a specific frequency. This method allows for accurate determination of molecular weight and can be used to study the size and structure of macromolecules.
What to use instead of frisbee?
You can use a plastic plate but not paper or possibly a rubber disc
What happens to the bacteria in the clear area around the paper disc soaked in spot lotion?
9
What happen with the bacteria clear area around the paper disc soaked in spot-lotion?
The clear area around the paper disc soaked in spot lotion indicates that the spot lotion has antibiotic properties that inhibit bacterial growth. The active ingredients in the lotion diffuse outwards from the disc, creating a zone of inhibition where bacteria are unable to grow.
What are examples of a wheel?
A Ferris Wheel, a disc, a toilet paper roll/holder, a paper towel holder/roll, a tire, an airplane propeller, shapes such as the circle
What is the method of programming a floppy?
You don't "program" a floppy, you 'format' it. The computer will generally do it for you when you first insert the disc.
