Release choked

Deaths of target organisms associated with intentional pesticide applications to insect-infested crops, weed-choked roadsides, and nematode-laced fields are predictable, desirable, and relatively easy to measure. Likewise, catastropic releases of chlorine from ruptured tank cars or of crude oil from scuttled supertankers may produce a spectrum of biological effects including toxicity. These events are easily associated with exposures to toxic substances and particular environmental circumstances. 

With a ratio between storage pressure and ambient pressure of about 2 or greater (for air), the flow rate is limited to the sonic velocity of the fluid at the end of the flow restriction (choked flow). At this point, the fluid pressure can be greater than the ambient pressure. The remaining expansion occurs beyond the flow restriction, where the release accelerates both radially and axially. 

This method of releasing yourself from a choking grip utilizes the wrist throw. Thumb on back of hand and fingers to the palm. 

ONE MORE relea se from being choked. This Jio-Jitsu number looks spectacular but it is easy to perform. Actually a small person can release himself from, and throw, a much larger and stronger... 

The gas leak had devastating effects on the exposed population. Over 200000 residents (that comprised about one-fourth of the total population of city of Bhopal) were exposed to MIC and other related toxic gases released from the plant. Most of these residents were from the poor class and were living in the immediate surroundings of the Union carbide plant. The human mortality is estimated to be between 2500 and 5000 from this accident. Respiratory failure due to MIC inhalation was the principal cause of death. MIC caused bronchial necrosis and pulmonary edema. Within the first 24 h after the accident, 90 000 patients were admitted in local hospitals and clinics with multiple symptoms of respiratory distress, breathlessness, choking, cough, chest pain, and hemoptysis. Acute ophthalmic effects were also reported with severe eye irritation and watering of the eyes. 

In [300-302], thermohydrodynamic problems for non-Newtonian fluids were studied under the assumption that temperature varies along the walls of the tube (or channel) in this case, convective heat transfer plays an important role. It was assumed that the dependence of the apparent viscosity of the medium on temperature is exponential or power-law dissipative heat release was neglected. In one-dimensional steady-state flows of this type, the pressure gradient varies along the tube. It was shown that in some cases a situation typical of thermal explosion may arise. In this situation, heat supply due to fluid convection exceeds heat withdrawal through the walls. It was also discovered that there exists another mechanism for crisis phenomena to arise. If there is a constant heat withdrawal from the tube walls and the fluid velocity is sufficiently small, then the intensive cooling of the fluid may result in an accelerated increase of the fluid viscosity, which, in turn, results in flow choking.
