Hydrocephalus is due to a problem with the flow of the fluid that surrounds the brain. This fluid is called the cerebrospinal fluid, or CSF. The fluid surrounds the brain and spinal cord and helps cushion the brain. CSF normally moves through the brain and the spinal cord and is soaked into the bloodstream. The flow of CSF is blocked.
The Tesla Model S has a collision avoidance assist system that automatically engages the brakes to reduce the impact of a frontal collision. Automatic emergency braking will stop applying the brakes when the driver presses the accelerator pedal, the brake pedal, or sharply turns the steering wheel.
The Tesla Model S does not have a heat pump but uses waste heat recovery from the drive unit and power electronics to heat its battery-in addition to an electric battery and cabin heater. Nissan Leaf uses a simple (not injected) heat pump. GM Volt and Spark EV use resistive heating. As to future models, we donât know what Tesla will use in the Model 3 or what GM will use in Bolt EV. Tesla hinted at some new HVAC tech during the Model 3 unveiling.
