Usually, the egg will be implanted between 6 to 12 days of egg retrieval. After five days of embryo transfer, the egg reaches blastocyst stage. For accuracy, you need to county the day of retrieval as day 0.
A motor car engine is an Internal Combustion Engine (ICE). Energy is created by burning either diesel or petrol in a combustion chamber. In such an engine, the energy is transferred from the pistons moving up and down at high speeds. This up-down motion is converted to a rotary motion through the crankshaft and axle.

The sensor is part of the emissions control system and feeds data to theÂ­ engine management computer. The goal of the sensor is to help the engine run as efficiently as possible and also to produce as few emissions as possible. Â­A gasoline engine burns gasoline in the presence of oxygen (see How Car Engines Work for complete details).
