Question 1 Critique Dr. Honeydew’s report. Specifically‚ discuss what is missing and how the missing information should have been presented. First the PH measurements‚ Dr. honey dew does not explain how the PH device was calibrated or if the blood sample was added or mixed with anything prior to the measuring of the pH (like water‚ etc.). In regards to the absorption spectroscopy‚ the method by which the concentration was obtained is questionable. Was the concentration known before the experiment

1881–82 a Russian inventor Nikolai Benardos created the first electric arc welding method known as carbon arc welding‚ using carbon electrodes. The advances in arc welding continued with the invention of metal electrodes in the late 1800s by a Russian‚ Nikolai Slavyanov (1888)‚ and an American‚ C. L. Coffin (1890). Around 1900‚ A. P. Strohmenger released a coated metal electrode in Britain‚ which gave a more stable arc. In 1905 Russian scientist Vladimir Mitkevich proposed the usage of three-phase electric

Experimental Report: Oxidation and Reduction Factors Affecting Electrochemical Cells Research Question: How do the changeable electrodes of different reactivity affect the energy in Volts measured by a Voltmeter while the Solution and the Salt Bridge stay constant for every single trial by the same amount in each beaker? Background Theory: The conductance of an electrolyte depends upon the number of ions present in the solution. Therefore‚ the greater the number of ions in the solution

Essay ON PAcemaker A pacemaker (or artificial pacemaker‚ is a medical device that uses electrical impulses‚ delivered by electrodes contacting the heart muscles‚ to regulate the beating of the heart. The primary purpose of a pacemaker is to maintain an adequateheart rate‚ either because the heart’s native pacemaker is not fast enough‚ or there is a block in the heart’s electrical conduction system. Modern pacemakers are externally programmable and allow the cardiologist to select the optimum pacing

The polymerase chain reaction (PCR) is a biochemical technology in molecular biology used to amplify a single copy or a few copies of a piece of DNA across several orders of magnitude‚ generating thousands to millions of copies of a particular DNA sequence. Developed in 1983 by Kary Mullis‚[1][2] PCR is now a common and often indispensable technique used in medical and biological research labs for a variety of applications.[3][4] These include DNA cloning for sequencing‚ DNA-based phylogeny‚ or

Cell Osmotic Fragility‚ Solute Permeability and Diffusion Potentials of Permeable Membranes Introduction This experiment examines cell membrane permeability‚ osmosis and membrane voltages; all of which are important in understanding how cells are affected by their environment. The movement of water across membranes is important for cell volume and thus the volume of extracellular compartments. The mechanisms for solute transport are essential in maintaining cell functions and homeostasis. Furthermore

can be used. It is made by connecting a voltmeter between two electrodes‚ which are immersed in to the two different solutions separated by porous barrier. This barrier allows flow of ions‚ so that the voltage or potential can be measured. In a closer look of such reactions‚ it can be determined that the sum of the potentials of oxidation and reduction is actually the voltage of the whole voltaic cell. For convenience negative electrode of the voltaic cell is considered to be that where oxidation

electric spark is used as the cutting tool to cut (erode) the workpiece to produce the finished part to the desired shape. The metal-removal process is performed by applying a pulsating (ON/OFF) electrical charge of high-frequency current through the electrode to the workpiece. This removes (erodes) very tiny pieces of metal from the workpiece at a controlled rate. EDM EDM (electrical discharge machining) is a machining method primarily used for hard metals or those that would be impossible to machine
