Body language the investigators' themselves. The body language of the members of law enforcement might influence the accuracy of eyewitness accounts. The game of poker involves not only an understanding of probability, but also the competence of reading and analyzing the body language of the opponents. A key component of poker is to be able to "cheat" the opponents. To spot these cheats, players must have the ability to spot the individual "ticks" of their opponents. Players also have to look out for signs that an opponent is doing well. Kinesics is the study and interpretation of nonverbal communication related to the
Well test of volume flowrate e.g., m³/day), formula_3 is the aquifer loss coefficient (which increases with time — as predicted by the Theis solution) and formula_4 is the well loss coefficient (which is constant for a given flow rate). The first term of the equation (formula_5) describes the linear component of the drawdown; i.e., the part in which doubling the pumping rate doubles the drawdown. The second term (formula_6) describes what is often called the 'well losses'; the non-linear component of the drawdown. To quantify this it is necessary to pump the well at several different flow rates (commonly called "steps"). Rorabaugh
