Full-wave rectified three-phase 6 pulse units provide an x-ray beam at _____ per second.

A sample of blood is found to contain 64.5 micrograms of valproic acid. (1mg=1000ug   u=micro) How many milligrams of valproic acid does this blood sample contain? numerical answer only   Answer must be in correct amount of significant digits.       

1A) (5 points) A metal bar has a cross section of 1 by 2 cm2 and is made of copper . Thermocouples are inserted at 2 mm and 4 mm below the surface of the bar are reading Ttc1 = 40°C and Ttc2 = 42°C. Estimate the surface temperature of the top of the bar. Assume bar’s sides are insulated.  

Problem 3. (40 points) An air-cooled heat sink with 9 plate fins is used to maintain a CPU at 80°C. There is contact resistance of  between the CPU and the base of the sink. Thermal conductivity of the heat sink is 160 W/(m×K). Geometric variables are as follow: fin thickness (tf) = 2 mm, fin length (Lf) = 12 mm, cross-sectional shape of CPU = 2 cm x 2 cm (square), heat sink’s base thickness (tb) = 3 mm. Air temperature is 25°C and convection coefficient is 50 W/(m2K). Ignore internal heat generation and radiation heat transfer. Assume that the fin tips are adiabatic. Draw a thermal resistance circuit that expresses the heat transfer from the CPU’s top surface to air. Below the circuit show the expressions for thermal resistances (e.g., expression for a radiation resistance is 1/hrA). Then, determine the 1) total resistance in K/W (or °C/W) 2) overall fin efficiency and 3) heat rate from CPU to air in W.

Which of the following is an Inborn Error of protein metabolism?

You are admitting a 2 day old infant to the NICU from the well baby nursery after the infant presented with tachycardia and was placed on a monitor. The monitor telemetry was concerning for arrhythmia. In reviewing the maternal history, you note that the mother was G2 now P1, GBS positive with appropriate intrapartum antibiotics, and has a history of tonsillectomy, appendectomy, and radio ablation of the thyroid for Grave’s disease. She is taking prenatal vitamins, iron, and Zofran. Your recognize the potential for which of the following neonatal problems?

Gallaghan Mattress in Batavia, NY makes box springs. Each spring either passes or fails inspection.  These box springs are independent and each has a probability of failing inspection equal to 0.078.  This copywritten question is part of a quiz or exam at Arizona State.  It may not be posted to Chegg.com or to any other website or reproduced without the permission of the author, Dr. L. Chattin, and Arizona State University.  Forty-five of these box springs are tested.  What is the probability that more than three of the springs fail inspection? Express your answer to two decimal places using conventional rounding methods.
