Add and/or adhd (attention deficit [& hyperactivity] disorder) rates have skyrocketed in the contemporary usa, but they vary across cultural/ethnic lines\.\* this suggests that adhd is, in many ways, a 'culture bound syndrome.' for this db post, i want you to undertake a thought experiment: 1) define the term 'culture bound syndrome' and then, using your intellect (i. e., not google! ): 2) propose at least two features of contemporary western culture (which includes the institution of k-12 education) that foster high rates of add/adhd in us children/youth. 3) explain how they do so. 4) explain why things might not be this way in a contrasting cultural context.

Amass of m 1.5 kg of steam is contained in a closed rigid container. initially the pressure and temperature of the steam are: p 1.5 mpa and t 240°c (superheated state), respectively. then the temperature drops to t2= 100°c as the result of heat transfer to the surroundings. determine: a) quality of the steam at the end of the process, b) heat transfer with the surroundings. for: p1.5 mpa and t 240°c: enthalpy of superheated vapour is 2900 kj/kg, specific volume of superheated vapour is 0. 1483 m/kg, while for t 100°c: enthalpy of saturated liquid water is 419kj/kg, specific volume of saturated liquid water is 0.001043m/kg, enthalpy of saturated vapour is 2676 kj/kg, specific volume of saturated vapour is 1.672 m/kg and pressure is 0.1 mpa.

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.

You are making beer. the first step is filling the glass carboy with the liquid wort. the internal diameter of the carboy is 15 in., and you wish to fill it up to a depth of 2 ft. if your wort is drawn from the kettle using a siphon process that flows at 3 gpm, how long will it take to fill?
