Compute φVn for the cross section shown. Assume f’c = 3,000 psi, fyt = 40,000 psi, d = 24 in., w = 18.5 in., t = 4 in., and that there are four No. 9 longitudinal tension bars and No. 4 stirrups at 8 in. o.c.

Stirrups are unable to resist shear unless they are crossed by an inclined crack.

A beam has dimensions of b = 14 in., h = 26 in., d’ = 2.5 in., and d = 23.5 in. It is reinforced with 2 No. 5 bars on the compression side and 4 No. 8 bars on the tension side. The concrete strength is 2,800 psi, and the yield strength of the reinforcement is 60,000 psi. For the results given below, determine the strength Mn for this beam.a = 4.828 in. (depth of concrete stress block)Cc = 159.4 kips (compressive force in concrete)Cs = 30.2 kips (compressive force in steel)T = 189.6 kips (tensile force in steel)

Medications to treat generalized anxiety disorder (GAD) can include a selective serotonin reuptake inhibitor (SSRI), and/or serotonin and norepinephrine reuptake inhibitor (SNRI).These medications are advantageous due to the following affects:

Which of these blood pressure readings is considered to be Stage 2 hypertension per the American Heart Association guidelines?

When faced with severe architectural restrictions on the dimensions of a beam, a designer may be forced to use a doubly reinforced section.

A beam has dimensions of b = 14 in., h = 26 in., and d = 23.5 in. and is reinforced with 3 No. 5 bars. The concrete strength is 4,000 psi, and the yield strength of the reinforcement is 60,000 psi. Determine the strength Mn for this beam.

How do shearing stresses on horizontal and vertical planes through an element compare?

Your next patient is a 36-year-old female coming into the clinic today to see you in your primary care clinic for an exacerbation of her psoriasis. Her psoriasis was diagnosed in middle school. It seems that her lesions are getting thicker, and scalier as she gets older. She has been using different topical treatments for years and she is wondering if there is any “new treatment”.  She does not have any other health issues. She is excited about spending more time outside during the spring. She loves to run and do other outdoor activities.  Which of the following statements is true about psoriasis?
