Outpatient Fall Prevention In Ambulatory Adults 65 Years Old And Over, Dorothy L. Osborne-White

Doctor of Nursing Practice (DNP) Scholarly Projects - Archive

Background: In the United States (U.S.), falls are the leading cause of injury among adults 65 and over, resulting in 36 million falls yearly (Moreland et al., 2020). According to the Centers for Disease Control and Prevention (CDC, 2023), one in four older adults experiences a fall each year. Falls are the world's second most prominent cause of accidental deaths (World Health Organization [WHO], 2021). Falls are the leading cause of both fatal and non-fatal injuries among older adults (Moreland et al., 2020).

Methods: A quality improvement project that included a fall bundle was implemented in a primary clinic. A …


Determination Of Traces Of Heavy Elements (Pb, Zn, Cu, Cd, Ca And Mg) In Human Teeth From Klang Valley And Malacca Using Icp-Aes And Xrf Techniques, Chea Beng Lee Jan 2002

Determination Of Traces Of Heavy Elements (Pb, Zn, Cu, Cd, Ca And Mg) In Human Teeth From Klang Valley And Malacca Using Icp-Aes And Xrf Techniques, Chea Beng Lee

Student Works (2000-2009)

X-ray Fluorescence (XRF) and Inductively Coupled Plasma-Atomic Emission Spectrometry (ICP-AES) have been used to study the concentration of heavy metals in human teeth. XRF technique has been used to determine Pb concentration in human teeth with the excitation source ofTc-99m combined with an XR-IOOT-CZT detector. The sensitivity of this system to determine the concentration of Pb lower than 800 ppm was constrained by Tc-99m's y-ray energy of 140.5 keV. High percentage errors in the calculation of average mean of differences for each concentration (from 100 ppm to 800 ppm) were found if compared with the respective background measurements which caused …
