An insulator is applied around copper wires in a circuit to prevent accidental electrical contact, ensuring safety by reducing the risk of electric shock and protecting the wires from short circuits.
Two methods the pharmaceutical company might choose to extract an ingredient from pomace are solvent extraction and mechanical pressing. One criterion that could influence the decision is the purity of the extracted ingredient needed for pharmaceutical use, which may favor solvent extraction due to its ability to selectively dissolve specific compounds. A constraint that could affect their choice is the cost of extraction; for example, mechanical pressing may be less expensive and faster but yield lower purity compared to solvent extraction, leading the company to balance cost against the desired quality of the final product.
