An amino alcohol corrosion inhibitors can be mixed within the fresh concrete (admixture inhibitor), or can be applied on the surface of existing concrete structures. In this study the contribution of both types' admixtured and spraying applied corrosion inhibitors was investigated. Moreover, when the corrosion action was under progress,

Corrosion inhibitors N, N'-ortho-phenylenacetyle acetone imine (S1) and 4-[(3-{[1-(2-hydroxy phenyl)methylidene]amino}propyl]ethanemidol]-1, 3-benzenediol (S2) have been studied as corrosion inhibitors on two different microstructures by impedance method in 1MHCl.20 Two different microstructures are produced by different heat treatment process. .

corrosion inhibitor. Two formaldehyde based chitosan derivatives based on thiosemicarbazide (TSFCS) and thiocarbohydrazide (TCFCS) ( Figure 4 ) were synthesized and investigated as effective corrosion inhibitors for heavy metals [21]. TCFCS behaved as mixed type corrosion inhibitor and showed maximum efficiency of 92% at 60 mg/L concentration.

A corrosion inhibitor is a chemical substance that, when added in small concentration to an environment, effectively decreases the corrosion rate [4]-[9]. The use of chemical inhibitors to decrease the rate of corrosion processes is quite varied. In the oil extraction and processing industries, inhibitors have al-

comparison of corrosion rates to determine if the corrosion inhibitor is providing a benefit. It was determined the inhibitor tested was a cathodic inhibitor so further testing should include anodic and mixed reaction inhibitors along with additional cathodic inhibitors to determine which is most effective.

mechanism of action of SGLT inhibitors is complementary and not alternative to the mechanisms of other antidiabetic agents. us, SGLT inhibitors may be suitable for use in a combination of approaches. Finally, because SGLT inhibitors increase glucose excretion and, therefore, calorie losses, they may cause a decrease in body weight. is may

RAF and MEK inhibitors are now approved and used in the clinic. There is now much interest in targeting at the level of ERK1/2 for a variety of reasons. First, since the pathway is linear from RAF-to-MEK-to-ERK then ERK1/2 are validated as targets per se. Second, innate resistance to RAF or MEK inhibitors involves relief of negative
