Definition: A method of farming that focuses on creating sustainable and self-sufficient ecosystems by using natural resources wisely and enhancing local environments.

Example: Many farmers are adopting permaculture practices to improve soil health and biodiversity.

Definition: Able to pass through or enter a material or substance.

Example: The permeant substance was able to move through the membrane easily.

Definition: A substance that can move through or enter a membrane or polymer.

Example: The scientist studied the permeant to understand how it interacts with the membrane.

Definition: To spread or pass through something, often in a way that affects the entire area.

Example: The smell of fresh bread began to permeate the room.

Definition: To spread or flow through something, especially in a way that fills or affects it completely.
