3) The concept of rapid increase in the production of fish and marine product through package programme is called as blue revolution. ... It has brought improvement in aquaculture by adopting new techniques of fish breeding, fish rearing, fish marketing, and fish export.

4) Single-layer boards, sometimes called single-sided boards, have components on one side of the board and a conductor pattern on the opposite side. They have just one layer of conductive material, typically copper. A single-layer board is comprised of a substrate layer, a conductive metal layer and then a protective solder mask and silk-screen. You'll find single-layer boards in many simpler electronic devices.

Multi-layer PCBs are made of three or more double-sided boards stacked on top of each other. Theoretically, they can contain as many boards as you can need, but the largest one ever made was 129 layers thick. Typically, they have an even number of between four and 12 layers — odd amounts can cause problems such as warping and twisting post-soldering.
