Increased reflectivity decreases both absorption and emission of radiation. Tensile strength decreases with increased water absorption. Astronomical spectra contain both absorption and emission spectral information. Smaller particle size allows for increased nutrient absorption. The intestine completes the process of digestion and nutrient absorption. FTIR is a method of measuring infrared absorption and emission spectra. Antacids may decrease the absorption of HCQ. Longer term regulation occurs through calcium absorption or loss from the gut. This combination resulted in optimal water absorption capacity. Potential is limited by poor absorption and rapid excretion. Anti-vitamins are chemical compounds that inhibit the absorption or actions of vitamins. Carbon filtering removes remaining contaminants and impurities by chemical absorption onto activated carbon. Such loss of energy causes gamma ray resonance absorption to fail. That demonstrated a kinship between the molecular mechanisms of absorption and emission. Covering the skin after application increases the absorption and effect.
