宪政文明与和谐社会

宪政文明是政治制度文明和政治主体文明的结合体。它要求良宪、民主、法治与人权四者的结合及在实践中的运作,进而形成具有实践的制度安排与价值追求。宪政文明是实现和谐社会的制度保障,是政治发展的目标性指向和规律性要求,具有合作、妥协与平衡的优良品格。宪政精神与和谐社会的内涵有着内在的暗合共通之处,为和谐社会价值目标的实现提供了一条现实的制度路径。     

The effects of corrosive substances on human bone, teeth, hair, nails, and soft tissue

Abstract: This research investigates the effects of household chemicals on human tissues. Five different human tissues (bone, tooth, hair, fingernails, and skin/muscle/fat) were immersed into six different corrosive agents. These agents consisted of hydrochloric acid, sulfuric acid, lye, bleach, organic septic cleaner, and Coca‐Cola^® soda. Tap water was used as a control. Tissue samples were cut to consistent sizes and submerged in the corrosive liquids. Over time, the appearance, consistency, and weight were documented. Hydrochloric acid was the most destructive agent in this study, consuming most tissues within 24 h. Sulfuric acid was the second most destructive agent in this study. Bleach, lye, and cola had no structural effects on the hard tissues of the body, but did alter the appearance or integrity of the hair, nails, or flesh in some way. The organic septic cleaner and tap water had no effect on any of the human tissue tested during the timeframe of the study.
