No two are exactly alike — even for identical twins.
The belly button is the scar on the abdomen that is caused when the umbilical cord, through which the mammalian fetus receives nourishment, is removed. Unlike other placental mammals, the human umbilicus is quite conspicuous. In humans, the navel is the center of gravity of the body.
Omphalos, an ancient religious stone artifact, means “navel” in Greek. The legend goes that Zeus had two eagles fly across the world to meet at its center, or omphalos. The mythologies of many cultures consider the navel a primary component of creation myths.
When the scar appears as a depression, it is referred to as an innie. When it appears as a protrusion, the opposite colloquialism applies: outie. Some who are unhappy with the appearance of their navel opt for umbilicoplasty, or belly button surgery.
The navel was recently in the news. A study found that runners of West-African origin typically have a higher center of gravity than their competitors of European origin. In other words, their belly buttons give them an advantage on the track. Europeans have an advantage in swimming competitions because they typically have longer torsos and lower belly buttons. No mention was made regarding the effect of innies versus outies on performance. Do you think the center of the world is more likely in an innie or outie?
National Training Center (NTC)
Engineer April 1, 2000 | Bell, Steven; Neal, Robert On today’s battlefields, engineer leaders are, more and more, pressed for time. Therefore, they must make work efficiently between missions to reconsolidate, resupply, and prepare soldiers and equipment for future operations. Two recent trends in these areas have been identified during training at the National Training Center. First, companies and platoons often lack effective SOPS for tactical assembly area (TAA) operations. Second, too little focus is placed on preparing the unit’s equipment for continued operations. here gta 5 news
Engineer Platoon TAA Procedures Issue: Engineer platoons frequently do not have an SOP for TAA procedures.
Discussion: Engineer platoons often do not employ all chemical defense equipment (CDE). They also frequently do not establish tactical wire communications, protective obstacles, and listening posts/observation posts (LPs/OPs) for early warning.
Recommendation: Engineer platoons should develop specific SOPs for TAA procedures. The SOPS should be based on the company and battalion SOPs and doctrinal references such as FM 5-34, Engineer Field Data, pages 1-13 and 1-14. Emphasis should be placed on establishing priorities of work that enhance force protection. Security can be enhanced by performing quartering party operations, emplacing key weapons, emplacing CDE, establishing tactical wire (HOTLOOP) communications, maintaining radio listening silence on platoon FM nets, and performing “stand-to” procedures.
Volcano System Maintenance Issue: Engineer Volcano crews frequently conduct inadequate preventive maintenance checks and services (PMCS).
Discussion: Vibration during cross-country travel in the M548 chassis often causes bolts, nuts, and electrical connections to loosen during movement. This can result in three types of failures: mechanical failure of the mounting hardware resulting in damage to the launcher or display control unit (DCU) as the launcher shifts; electrical connectivity failure between the DCU and the launcher panels; and connectivity failure between the launcher panels and the canisters.
Recommendation: Units should conduct daily PMCS according to Training Manual 9-1095-208-10-l, Operator s Manual for Dispenser, Mine, M139 w/Mounting Kits. Units should conduct combat checks according to Graphic Training Aid (GTA) 5-10-42, Volcano Preventive Maintenance Checks and Services, during extended hauls. Crews should conduct PMCS according to GTA 5-10-42 and conduct a full built-in test (BIT) on the DCU in the assault position before execution. At a minimum, crews should conduct daily inspections of all mounting hardware for tightness and conduct a daily BIT test, especially after cross-country movement. go to web site gta 5 news
