Polypropylene, often referred to as olefin, is a synthetic fabric widely used for sofa upholstery due to its durability, stain resistance, and affordability. It's a plastic-based material, making it less susceptible to water damage and easy to clean, ideal for households with children or pets. Its colorfast quality ensures that the sofa fabric doesn't fade easily under sunlight. Moreover, polypropylene is lightweight and resistant to mildew, chemicals, and abrasions, contributing to its longevity. While it offers practical benefits, some may find its texture less luxurious compared to natural fibers like cotton or wool. However, advancements in manufacturing have improved its feel, making it a versatile and popular choice for contemporary sofa designs.
Deamination is a metabolic process in which the amino group (-NH2) is removed from an amino acid, resulting in the formation of a keto acid and ammonia. This reaction can occur through various mechanisms, including enzymatic action (e.g., by deaminases) or non-enzymatic means, such as chemical hydrolysis. Deamination plays a crucial role in the body's nitrogen metabolism, facilitating the conversion of excess amino acids into usable forms of energy or stored fats. It also prepares nitrogen from amino acids for excretion from the body in a less toxic form, such as urea in ureotelic organisms like humans. The process is vital for maintaining homeostasis and enabling the use of amino acids for energy production, especially during periods of fasting or limited carbohydrate intake.
When rendering a brick wall, the standard practice involves applying two coats: a base coat (or scratch coat) and a top (or finish) coat. The base coat provides a good foundation and helps the finish coat adhere properly, ensuring longevity and durability. The thickness of the base coat typically ranges from 8 to 12 mm, while the finish coat is around 6 to 8 mm, depending on the type of render and the desired outcome. Some projects may require a third coat, especially if a more refined or smoother finish is desired, or to correct any imperfections. Choosing the right type of render and applying it correctly is crucial for the best results and to protect the underlying brickwork from weather elements.
