Describe an accelerometer and what it measures.

An IV of 700 mL is ordered to infuse in 5 hours at a rate of 25 gtt/min. Drop factor: 20 gtt/mL. After 3.5 hours, you notice that 375 mL has infused. Round both final answers to the nearest whole number. What will be the new recalculated rate using the same tubing in mL/hr? What will be the new recalculated rate using the same tubing in gtt/min?

If a plant species shows thermal acclimation as the climate changes, we would expect to see that

In the phloem of angiosperms, sugars flow from to (general locations).  Positive pressure occurs in the (cell type) due to the active loading of (compound) from the transfer cells followed by the movement of (compound).  This pressure pushes the phloem sap through the at the ends of each conducting cell.  The sugars conducted by the phloem may have originally been produced by occurring in the leaves or by converting (compound) stored in roots or stems to sugars. 

Order: 125 mL Lactated Ringers to run at 20 mL/hour. The drop factor is 60 gtt/mL. The infusion started at 1100 hours.  How long will the IV last? (Express in hours and minutes) At what time will the infusion be completed? (Express final answer in military time) What will the flow rate be in gtt/min? Round final answer to the nearest whole number.

Consider the following incidents, retrieved from the OSHA database. On March 14, 2003, an employee of U C Berkeley, was working with a class 4 Nd:YAG near infrared open beam laser. He wore laser safety eyewear during beam alignment, but afterward, he removed the safety eyewear. While taking a meter measurement for output energy, his eye caught a flash from a hidden optic in the beam’s path. His exposure exceeded current limits for lasers. The exposure to laser damaged the macula in his retina, resulting in irreversible retinal damage and loss of visual acuity. At approximately 3:00 p.m. on March 18, 1996, Employee #1, an assistant project scientist working in the laboratory of Dr. Kent Wilson at the University of California at San Diego, was aligning a 50 Hz, 800 nm tera-watt laser system for an experiment. As he was viewing the laser focus through a chamber window, he became exposed to nondirect laser light. The approximate laser intensity was 3 watts at 50 Hz, producing about 60 mJoules/pulse of energy. During this brief period of alignment, Employee #1 had removed his protective eyewear. He suffered a serious injury to both eyes that involved partial vision loss. After this incident, it was determined by the U.C.S.D. Environmental Health and Safety Department that two similar incidences had occurred earlier to another worker. Sometime on the evening of December 28, 1995, Employee #2, a research chemist in the same lab and a coworker of Employee #1, was performing the identical procedure as previously described. During the period of alignment, he removed his protective eyewear and suffered a serious injury to both eyes involving partial vision loss. Employee #2 sought medical attention at a later date. The second incident occurred on March 16, 1996. Again, the alignment of the laser into the chamber was being performed. When Employee #2 removed his safety glasses to view the focus, both of his eyes were again exposed to nondirect laser light. The intensity and power of the laser were approximately the same as noted for Employee #1. The causal factors for all three incidences were unsafe work practices and, more specifically, removing protective eyewear during the alignment of the 50 Hz, 800 nm tera-watt laser system. The accidents occurred at an academic research laboratory that specialized in laser science and, specifically, in the construction of high-intensity, ultra-short laser, and x-ray systems to view molecular dynamics. Analyze both cases involving laser use in a laboratory, and research using laboratory lasers for further information and answer the following questions.
