The Haddon Matrix is the most commonly used paradigm in the injury prevention field. Developed by William Haddon in 1970, the matrix looks at factors related to personal attributes, vector or agent attributes and environmental attributes; before, during and after an injury or death. By utilizing this framework, one can then think about ...
The Drainage anti-slide pile (DASP) is a reinforced concrete structure with a hollow upper section and a solid lower section, designed to resist slope deformation. [2] [3] The hollow part is filled with compacted, high-permeability gravels and can drain water via a vertical drain-pipe or sub-horizontal pipes connected to the slope surface. [2] [3]
Injury prevention is an effort to prevent or reduce the severity of bodily injuries caused by external mechanisms, such as accidents, before they occur. Injury prevention is a component of safety and public health , and its goal is to improve the health of the population by preventing injuries and hence improving quality of life .
The U.S. Centers for Disease Control and Prevention's National Center for Injury Prevention and Control's mission is to provide leadership in preventing and controlling injuries, i.e., reducing the incidence, severity, and adverse outcomes of injury, the leading cause of death for those aged 1 – 44.
Penetrating trauma is an open wound injury that occurs when an object pierces the skin and enters a tissue of the body, creating a deep but relatively narrow entry wound.In contrast, a blunt or non-penetrating trauma may have some deep damage, but the overlying skin is not necessarily broken and the wound is still closed to the outside environment.
In non ideal fluid dynamics, the Hagen–Poiseuille equation, also known as the Hagen–Poiseuille law, Poiseuille law or Poiseuille equation, is a physical law that gives the pressure drop in an incompressible and Newtonian fluid in laminar flow flowing through a long cylindrical pipe of constant cross section.

The glass is then rapidly cooled with forced air drafts while the inner portion remains free to flow for a short time. An alternative chemical toughening process involves forcing a surface layer of glass at least 0.1 mm thick into compression by ion exchange of the sodium ions in the glass surface with potassium ions (which are 30% larger), by ...
