Flushing is a critical step in the hydraulic piping procedure as it ensures the cleanliness of the piping. Given the variety. of hydraulic systems, it is important that the relevant professionals are present at a very early stage to set the right goals. for the level of purity. The desired level of purity can be influenced e.g. by different types of valves (proportional or servo. valves), pumps, cylinders, motors, and oil viscosity.
Hibernation is a way that some animals deal with the harshness of winter. They curl up in a safe place and stay there until winter ends. Hibernating animals seem almost dead. They barely breathe, and their body temperature is near the freezing mark.
For the purposes of this article, we'll use the term hibernation to describe any long-term reduction in body temperature (hypothermia) and metabolism during winter months. When an animal enters a hibernationlike state during the summer, it's known as estivation. It's much less common than hibernation. Hibernation in reptiles is sometimes called brumation. It differs from mammalian hibernation because reptiles are cold-blooded -- they can't control their own body temperature, so they need to spend the winter in a place that will stay warm enough.
