working memory buffers the visuospatial sketchpad and the phonological loop. The central executive has multiple important jobs like adding or deleting items in the buffers above‚ selecting items to guide behavior‚ retrieving information from long-term memory and transferring information to long-term memory. It works like a train it goes back and forth between short and long-term memory. The central executive only manipulates information while the two buffers manage the information. The buffers are material

History of Pulse Oximetry Before the Pulse-Oximeter the only way to measure SpO2 was by using a painful arterial blood gas which took a minimum of 20-30 minutes to view the result. In 1974 Takuo Aoyagi a Niigata University student disclosed his first Pulse-Oximeter for the use of pilots in World War 2. He set about searching for a non-invasive way of monitoring arterial blood oxygen saturation. Nellcor’s pulse oximeter was put on the market in 1983 and this used his theory developed in 1974. By

BRONSTED-LOWRY ACIDS AND BASES 1. The Bronsted-Lowry definition There are many definitions of acids and bases in existence‚ but the most useful one is the Bronsted-Lowry definition: An acid is a substance which can behave as a proton (re presented as a hydrogen ion‚ H+) donor. Any substance which contains hydrogen bonded to a more electronegative element can thus behave as an acid: HCl == H+ + Cl- H2SO4 == H+ + HSO4- A base is a substance which can behave as a proton acceptor.
