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.
Low-density polyethylene (LDPE), sometimes referred to as high-pressure, low-density. polyethylene, conventional polyethylene, or branched polyethylene, has been commercially. produced since its discovery in the 1930s. These polymers are produced in large volumes by.
