Discharge tests

Polyaniline (PANI) was investigated as electrocatalyst for the oxygen reduction reaction in the acidic and neutral solutions. Galvanostatic discharge tests and cyclic voltammetry of catalytic electrodes based on polyaniline in oxygen-saturated electrolytes indicate that polyaniline catalyzes two-electron reduction of molecular oxygen to H2O2 and HO2". [Pg.124]

Impact on the environment may result from both unwanted fires, improper control of fire effluent or improper use of suppression system agents. Environmental considerations impact decisions on whether to provide protection for a hazard, and whether this protection should be provided automatically or manually. Scenarios to be considered include uncontrolled fires, potential hazardous situations, firefighting training, and fixed or mobile vehicle suppression system discharge testing. [Pg.89]

III.b.1.1. Anion inhibitors. Perchlorate, periodate, pertechnetate and thiocyanate (a naturally occurring goitrogen) are classified as iodide pump inhibitors, antagonizing iodide transport through competitive inhibition. This effect can be overcome by large dose of iodides. Perchlorate is used to block reuptake of iodide in cases of amiodarone induced hyperthyroidism and for the perchlorate discharge test . [Pg.759]

The thyroidal mechanism used for concentrating 1 may also concentrate other monovalent anions, including pertechnetate, perchlorate, and thiocyanate, within the follicular lumen. However, none of these anions become incorporated into Tg, although they may act as a competitive inhibitor of 1 transport. The ability of the thyroid gland to concentrate radioactive pertechnetate makes it a useful agent for thyroid imaging, since it is concentrated by the thyroid cells without further metabolism. The perchlorate and thiocyanate discharge tests make use of the ability of these anions to inhibit 1 transport to test for defects in the incorporation of 1 into Tg. [Pg.744]

The perchlorate ion of potassium perchlorate, KCIO4, is a competitive inhibitor of thyroidal 1 transport via the Sodium Iodide Symporter (NIS).This drug can cause fatal aplastic anemia and gastric ulcers and is now rarely used. If administered with careful supervision, in limited low doses and for only brief periods, serious toxic effects can be avoided. The compound is especially effective in treating iodine-induced hyperthyroidism, which may occur, for example, in patients treated with the antiar-rhythmic compound amiodarone. Perchlorate ion can also be used in a diagnostic test of 1 incorporation into Tg, the so-called perchlorate discharge test. [Pg.751]

A special type of an electrostatic discharge test is one which seeks to determine dust explo-sibility (Ref 18, pp 2—13). This author has never seen any data which proves this test to be of any particular value in establishing a threshold initiation level of certain pyrot powders such as flash compns and their ingredients such as metallic Zr powder... [Pg.255]

The periodic inspection and annual maintenance of foam systems and concentrate are key to their reliable operation. Full discharge tests can be conducted as part of personnel training activities that are key to effective and successful application. [Pg.52]

Classic texts on dielectric breakdown phenomena are by Whitehead (1951) and O Dwyer (1973). A more recent book by Dissado and Fothergill (1992) provides a comprehensive review of advances since then. Sillars (1973) gives a good review of test methods and materials. Discharge testing techniques are described by Kxeuger (1964). [Pg.214]

Charge and discharge tests were carried out by using the experimental cells which were assembled in an argon dry box at room temperature. The cathode was prepared from a mixture of 85wt% LiNi,., Co, V04 as the active materials, 12wt% acetylene black and 3wt%... [Pg.516]

The determination of SoH can be achieved by discharging a fully charged battery until the end-of-discharge voltage is reached. This method is consistent with the definition of SoH and, therefore, the exact value of SoH can be computed. In most applications, however, it is not possible to carry out discharge tests, due to limitations of the power equipment or the lack of access to the battery. In the case of... [Pg.226]

The alkaline Mn02-Zn cell performs well even at low temperatures and far exceeds the Leclanche cell. Figure 11 illustrates the room temperature service of a C size cell and its performance at lower temperatures on a 2.25 Q continuous discharge test. The cell can operate at temperatures as low as - 40°C. Figure 12 shows the capacity of typical C and D size alkaline... [Pg.172]

The Wolff-Chaikoff effect is evidenced by the perchlorate discharge test, i.e., the release of radioiodide by the thyroid in response to perchlorate after administration of high levels of iodide. The fraction of the trapped iodide that is not organified is released by perchlorate. [Pg.305]
