What percentage of children diagnosed with adult deficit/hyperactivity disorder (ADHD) will continue to experience ADHD symptoms into adulthood?

At a point subjected to plane stress, the stresses are σx = 20 ksi, σy = 10 ksi, and τxy = –10 ksi. Determine the angle θp corresponding to the orientation of the principal planes at the point.

Which correctly describes the heart’s apex?

Compute φVn for the cross section shown. Assume f’c = 3,000 psi, fyt = 60,000 psi, b1 = 23 in., b2 = 12 in., d = 24 in., h1 = 4 in., h2 = 17 in., h3 = 8 in., t = 7 in., and that there are six No. 6 longitudinal tension bars and No. 5 stirrups at 9 in. o.c.

What causes vertical cracks to occur first?

A 56-year-old female with non-ischemic heart failure and hypertension presents to the office for a routine follow-up. Her last hospitalization for a congestive heart failure (CHF) with HFrEF (reduced ejection fraction) exacerbation was two years ago. Currently, she has is not complaining of shortness of breath, orthopnea, leg edema, or chest pain. She has been following a low-salt diet and does not drink alcohol. Her medications are carvedilol and a baby aspirin. Her home blood pressure measurements have ranged from 140-150/80-90 mmHg. Her physical exam findings are notable for a blood pressure of 150/90 mmHg. Her pulse is 60 beats/minute with S1S2 with no murmurs or gallops. Her respiratory rate is 12/minute. Her jugular venous pulse and pressure (JVP) is within the normal range and her lungs are clear bilaterally. Her point of maximal impulse (PMI) is laterally displaced. What medication should you add that can also improve her mortality from heart failure?

For a beam with stirrup hooks, the free end of the bar must extend at least _____ from the hook. Assume b = 15 in., d = 29 in., and that there are four No. 6 longitudinal tension bars and No. 5 stirrups at 8 in. o.c. The stirrup hooks are 135°.
