The phenomenon of freezing-point depression has many practical uses. The radiator fluid in an automobile is a mixture of water and ethylene glycol. The freezing-point depression prevents radiators from freezing in winter. Road salting takes advantage of this effect to lower the freezing point of the ice it is placed on.
Finally, many commercial radiator antifreeze products have fluorescein added to enable radiator leaks to be detected using a Wood's lamp. Following ingestion of antifreeze products containing ethylene glycol and fluorescein, a Wood's lamp may reveal fluorescence of a person's mouth area, clothing, vomitus , or urine which can help to diagnose ...

These risky driving behaviors are associated with depression as contributing factors to vehicular suicide. [9] Impact velocity may be maximized by exceeding speed limits or by maneuvering into a head-on collision with a heavier and less maneuverable vehicle like a bus or semi-trailer truck .
In addition, driving drowsy can have an impact on your car insurance.If you get into an accident due to fatigue, your car insurance rate could increase significantly. And, if the crash results in ...
A system of valves or baffles, or both, is usually incorporated to simultaneously operate a small radiator inside the vehicle. This small radiator, and the associated blower fan, is called the heater core, and serves to warm the cabin interior. Like the radiator, the heater core acts by removing heat from the engine.
A rut is a depression or groove worn into a road or path by the travel of wheels or skis. Ruts can be formed by wear, as from studded snow tires common in cold climate areas, or they can form through the deformation of the asphalt concrete, pavement or subbase material. In modern roads the main cause is heavily loaded trucks.
[21] [22] A negative surge of voltage (down to 7V) can cause rebooting of the ECU, resulting in the output APS (accelerator position) and TPS (throttle position) reaching 100% while the physical accelerator is still consistently held at 37%. In the study cited, a laparoscopic camera positioned inside the engine confirmed that 100% TPS ...
