Fiber is not classified as a simple carbohydrate; it belongs to the complex carbohydrate category. Simple carbohydrates consist of one or two sugar molecules and are found in foods like fruits, milk, and sugar. Fiber, on the other hand, is a type of carbohydrate that the human body cannot digest. It is found in plant-based foods such as vegetables, fruits, legumes, and whole grains. Unlike simple carbohydrates, which are quickly broken down and absorbed for energy, fiber passes through the digestive system almost intact, providing various health benefits such as improving digestion, aiding in weight management, and reducing the risk of heart disease.

Adhesives are measured and evaluated using several units depending on the aspect of the adhesive being considered. For the quantity or volume, common units include liters, milliliters, and ounces for liquid adhesives, and grams or kilograms for solid forms like tapes or sheets. The effectiveness and strength of an adhesive are often measured in terms of psi (pounds per square inch) for tensile strength, which tells us how much force the adhesive can withstand per unit area before failing. Additionally, in research and technical specifications, you might encounter measurements related to the adhesive's properties such as viscosity (measured in centipoise or Pascal seconds), peel strength (measured in pounds per inch or Newtons per millimeter), and shear strength (also measured in psi or MPa - MegaPascals). Choosing the correct unit of measurement is crucial and depends on the specific attributes of the adhesive being analyzed or the requirements of the application where the adhesive will be used.

Applying commercial epoxy sideways refers to coating vertical surfaces. Preparation is crucial: clean and sand the surface for better adhesion. Mix the epoxy resin and hardener according to manufacturer instructions. Use a roller or brush for application, starting from the bottom and moving upward to prevent drips. Apply in thin layers, allowing sufficient drying time between coats as recommended. Wear protective gear to avoid skin contact and inhalation hazards. It's advisable to work in a well-ventilated area and follow the specific product guidelines for best results. Small batches and repeated thin coats work better for vertical applications to avoid sagging.
