Infrared radiation is a type of electromagnetic radiation and invisible to human eyes. It is used widely in industrial, scientific, and medical applications. Pool fire is an emergent accident, which emits intense thermal radiation. In order to quantify the performance of water curtain fighting fire, a testing platform is built and experimental studies are carried out. An infrared imager is used...

effects of oral administration of testosterone and fluoxetine exposure on aggressive behavior of the fighting fish, betta splendens , were investigated. testosterone diluted in ethanol and sprayed on pre-weighted pellet to achieve concentrations of 0, 1, 2 and 4 mg/kg of hormone in food. two main behaviors were recorded: the time in front of mirror and duration of the gill flaring using a mirro...

The evolution of fatal fighting was investigated using evolutionary game theory. General considerations about the lifetime consequences of fighting behaviour are first discussed. A sequential assessment game is then developed in which a fight can end because a contestant either gives up or is killed. The results show that the balance between the value of the contested resource and the value of ...

This has remarkable implications. Since this quantity never changes sign, only one of R and G can ever be zero. If the initial value of (3) is positive, for example, only G can equal zero, and so only red can win. So this quantity is key in determining who will win the battle, and a side’s fighting strength – we shall call rR and gG the red and green forces’ respective fighting strengths – vari...
