Wind direction

In this paper, we identify and evaluate 42 tower crane safety risk factors specific to the Vietnamese construction industry based on their probability of occurrence, severity of impact, and associated risk levels. The paper reveals that the most probable risk factor is “Unfavorable winds (including intensity, direction, etc.)” with a mean value of 3.641.

Thermoregulation Heat loss occurs through five mechanisms: radiation (55–65% of heat loss), conduction (10–15% of heat loss, but much greater in cold water), convection (increased in the wind), respiration, and evaporation (which are affected by the ambient temperature and the relative humidity). The preoptic anterior hypothalamus normally orchestrates thermoregulation (Chap. 17). The immediate defense of thermoneutrality is via the autonomic nervous system, whereas delayed control is mediated by the endocrine system.
