Causes of Enlarged Prostate. BPH is a benign (non-cancerous) enlargement of the prostate that is extremely common in older men. It is generally thought to be caused by years of exposure to male hormones like testosterone. While BPH is benign and cannot spread to other parts of the body, it can cause problems.
1 Conduction is the transfer of thermal energy through direct contact between particles of a substance, without moving the particles to a new location.
Thermal energy refers to the energy contained within a system that is responsible for its temperature. Heat is the flow of thermal energy. In the context of mechanics problems, we are usually interested in the role thermal energy plays in ensuring conservation of energy. Almost every transfer of energy that takes place in real-world physical systems does so with efficiency less than 100% and results in some thermal energy. This energy is usually in the form of low-level thermal energy. Here, low-level means that the temperature associated with the thermal energy is close to that of the environment. It is only possible to extract work when there is a temperature difference, so low-level thermal energy represents 'the end of the road' of energy transfer.
