Project Fellow Interview Questions and Answers

The selective media for actinomycetes is called Actinomycete Isolation Agar (AIA).

• Actinomycete Isolation Agar (AIA) is a commonly used selective media for actinomycetes.

• AIA contains specific nutrients and inhibitors that promote the growth of actinomycetes while inhibiting the growth of other microorganisms.

• Examples of inhibitors used in AIA include cycloheximide and nalidixic acid.

• AIA is often supplemented with indicators such as bromothymol blue to detect acid production by...read more

An anti-parallel diode is used in a DC solenoid to protect the circuit from voltage spikes and reverse current.

• An anti-parallel diode is connected in reverse polarity to the solenoid coil.

• It allows the flow of current in one direction while blocking it in the opposite direction.

• When the solenoid is energized, the diode prevents voltage spikes by providing a path for the back EMF.

• It also prevents reverse current from flowing through the coil when the power is turned off.

• This p...read more

Two materials developed using 3D processes

• 3D printing can be used to create complex geometries and structures that are difficult to achieve with traditional manufacturing methods

• Materials such as metals, plastics, and ceramics can be used in 3D printing to create functional parts

• One example of a material developed using 3D printing is graphene aerogel, which has high strength and low density

• Another example is a titanium alloy developed using 3D printing, which has improved me...read more

NDVI is calculated by subtracting the reflectance of near-infrared light from the reflectance of red light and dividing it by their sum.

• NDVI = (NIR - Red) / (NIR + Red)

• NIR and Red values can be obtained from satellite or drone imagery

• NDVI values range from -1 to 1, with higher values indicating healthier vegetation

• NDVI can be used to monitor crop health, drought, and deforestation
