The spinal cord is connected to the brain by the brain stem. The medulla oblongata connects the spinal cord to other structures in the brain stem and the brain proper. The brain stem is responsible for some the most basic processes of survival, including the control of hunger, thirst, blood pressure, body temperature and breathing. Continue Reading.
Re: TPR Thermoplastic Rubber. Re: TPR Thermoplastic Rubber -- schase. ThermoPlastic Rubber TPR is best described a material which has both the characteristics of rubber and plastic. Typical applications are the hard rubber/plastic soles on many shoes or the the rubber/plastic material used on hane tool grips. ThermoPlastic Elastomer (TPE) are a softer version of TPR. TPEs permit fabrication of rubber-like articles with the speed, efficiency, and economy of injection molding, extrusion, or blow molding. This material is typically used where flexibility and soft-touch is desired in the application.
PTFE (PolyTetraFluoroEthylene) (also known as Teflon) is a fluorocarbon-based conformal coating. PTFE coatings can provide a low co-efficient of friction or slipperiness, corrosion and chemical resistance, heat resistance, dielectric stability, and chemical inertness to the circuit assembly.ikipedia definition: Conformal coating material is applied to electronic circuitry to act as protection against moisture, dust, chemicals, and temperature extremes that, if uncoated (non-protected), could result in damage or failure of the electronics to function.
