Heat Shrink Tubing, also called heat shrinkable tubing, is a tube that contracts when warmed. When heat is applied to the heat shrink tubing, the adhesive material inside of the tube is activated.The adhesive material then secures it to the wire or cable. The process allows the wire or cable and the heat shrink tubing to become one unified product. 2:1 - This heat shrink tubing will become half of its original size once heat is applied. 2  The original heat shrinkable tubing is twice as large as its shrunken form. 3  3:1 - This heat shrink tubing will be one third of its original size once heat is applied.
Biologically, conception is the moment when a sperm cell from a male breaches the ovum, or egg, from a female. The process is also known as fertilization and is the initial stage of development for human growth.
Short answer: Conception occurs when the egg is released from the ovary at ovulation and meets (is fertilized by) the sperm waiting in the fallopian tube. One sperm burrows into the wall of the egg which signals cells to grow and develop.This is the moment of conception, occurring within about 24 hours of ovulation.uccessful conception, however, does not occur until the embryo implants into the endometrium of the uterus. This is when you are considered officially pregnant. Which happens about a week to 10 days after ovulation.
