Poaceae have hollow stems called culms plugged at intervals by solid leaf-bearing nodes. Grass leaves are nearly always alternate and distichous (in one plane), and have parallel veins. Each leaf is differentiated into a lower sheath hugging the stem and a blade with entire (i.e., smooth) margins.oaceae have hollow stems called culms plugged at intervals by solid leaf-bearing nodes.

Air conditioning system components consisting of Condensing Unit, Evaporator Coil, Refrigerant line. How air conditioning works is kind of a mystery to many of us. Furnaces are easy to understand, they heat air and blow it around your home in ductwork.
An inverter air-conditioner is similar to a traditional air-conditioner and runs on vapour compression cycle. Inverter air conditioners differ with the traditional air conditioner in terms of the drive used by them to run the compressor . They have a variable feed drive compressor and are useful in varying the speed of the compressor-motor according to the room/enclosure conditions.
