Humans cannot digest cellulose due to the absence of the enzyme cellulase, which is necessary to break down cellulose into glucose units. Cellulose is a complex carbohydrate found in the cell wall of plants and is a major component of dietary fiber. Although humans lack the enzyme to digest it, bacteria in the human gut can partially break down cellulose, contributing to the fermentation process that produces short-chain fatty acids beneficial for colon health. However, most of the cellulose passes through the digestive system unchanged, aiding in the digestive process by adding bulk to the stool and helping prevent constipation.

SharkBite fittings, recognized for their push-to-connect design, offer compatibility with a wide range of pipe materials, including PEX, copper, CPVC, PE-RT, and HDPE. However, they are not designed for use with PVC (polyvinyl chloride) pipes directly as the differences in material properties and outside diameters between PVC and the pipes SharkBite fittings are designed for (like PEX and CPVC) can prevent a secure and leak-free connection. For projects requiring the connection of PVC pipes, alternative fittings specifically designed for PVC or transition adapters should be used to ensure a reliable, leak-proof system. Always consult the product’s specifications and adherence to local plumbing codes before proceeding.

PVD (Physical Vapor Deposition) coating process is a vacuum deposition method used to produce thin films and coatings. During the PVD process, the material goes from a condensed phase to a vapor phase and then back to a thin film condensed phase. The process involves three main steps: vaporization of the coating material, transportation of the vapor to the substrate, and condensation to form the film. PVD coatings are known for their durability, corrosion resistance, and aesthetic qualities. They are widely used in various industries, including automotive, aerospace, and electronics, for applications such as decorative finishes, tool coatings, and wear-resistant coatings. The different techniques within PVD, such as sputtering and evaporative deposition, offer versatility in the types of materials that can be deposited and the properties of the coatings.
