Sawing epoxy filler can be achieved by using the right type of blade to ensure a clean and precise cut without damaging the material. A fine-tooth saw blade, such as a hacksaw or a jigsaw with a metal cutting blade, is most suitable. Before cutting, ensure that the epoxy filler is completely cured, which usually takes at least 24 hours. Mark the area to be cut with a pencil or masking tape for accuracy. For best results, apply steady pressure and make the cut in a controlled manner. Using a saw with an adjustable speed setting can also help manage the cut's precision and avoid chipping or cracking the epoxy. Always wear protective gear, including gloves and safety glasses, to protect against dust and debris.

Polyvinyl Chloride (PVC) has a complex relationship with sunlight, particularly with the UV component. In its standard form, PVC can degrade over time when exposed to direct sunlight. The UV radiation can break down the chemical bonds in the PVC, leading to discoloration, loss of flexibility, and eventually, brittleness. However, it's important to note that additives can be mixed with PVC to enhance its UV resistance. These additives act by absorbing or blocking the UV radiation, thereby significantly slowing down the degradation process. For outdoor applications, it's crucial to use UV-stabilized PVC to ensure longevity and maintain structural integrity. Therefore, while untreated PVC may be susceptible to sunlight, treated PVC offers a more durable solution suitable for outdoor exposure.

Glucose, a simple sugar, is converted into cellulose through a series of enzymatic reactions inside plant cells. In the cytoplasm, glucose molecules are converted into UDP-glucose, a nucleotide sugar. Then, in the presence of cellulose synthase enzymes located in the cell membrane, UDP-glucose molecules polymerize to form long chains of beta-1,4-linked glucose units, known as cellulose. This process not only requires energy but also is regulated by the plant's developmental needs and environmental conditions. Cellulose, a major component of plant cell walls, provides structural support and rigidity to plants. It's an essential polysaccharide for the plant kingdom and also has immense importance for human industries, including textiles and paper, not mentioning its role as a dietary fiber.
