Case-hardening or carburization is the process of introducing carbon to the surface of a low-carbon iron, or more commonly a low-carbon steel object, in order to harden the surface. Iron which has a carbon content greater than ~0.02% is known as steel .
The Philippines' Bureau of Agriculture and Fisheries Product Standards (Filipino: Kawanihan ng mga Pamantayan sa Produktong Pansaka at Pampangisdaan, abbreviated as BAFS), is an agency of the Philippine government under the Department of Agriculture responsible for setting and implementing standards for fresh primary and secondary processed agricultural and fishery products.

Case hardening is a weathering phenomenon of rock surface induration. It is observed commonly in: felsic alkaline rocks, such as nepheline syenite , phonolite and trachyte ; pyroclastic rocks , as pyroclastic flow deposit, fine air-fall deposits and vent-filling pyroclastic deposits; sedimentary rocks , as sandstone and mudstone .
Hazard analysis and critical control points, or HACCP (/ ˈ h æ s ʌ p / [1]), is a systematic preventive approach to food safety from biological, chemical, and physical hazards in production processes that can cause the finished product to be unsafe and designs measures to reduce these risks to a safe level.
At 0-D there is precipitate and solid solution strengthening with particulates strengthening structure, at 1-D there is work/forest hardening with line dislocations as the hardening mechanism, and at 2-D there is grain boundary strengthening with surface energy of granular interfaces providing strength improvement.
Defects from uneven drying, resulting in the rupture of the wood tissue, such as checks (surface, end and internal), end splits, honey-combing and case hardening. Collapse, often shown as corrugation, or so-called washboarding of the wood surface, may also occur (Innes, 1996). Collapse is a defect that results from the physical flattening of ...
The National Food Authority was created by President Ferdinand Marcos through Presidential Decree No. 4 dated September 26, 1972, under the name National Grains Authority (NGA) with the mission of promoting the integrated growth and development of the grains industry covering rice, corn, feed grains and other grains like sorghum, mung beans, and peanuts.
