alloying additions (Mn‚ Cu‚ Sb and Zr) on microstructure and corrosion of Zn alloys and hot dip galvanised coatings was undertaken. The first part of this thesis focuses on the effect of alloying additions on the corrosion of Zn alloys. The result shows that Mn is the most beneficial addition‚ which can significantly improve the resistance of Zn. The effect of Cu depends on its concentration. A high level of Cu addition has a deleterious effect on the corrosion resistance as the Cu-rich particles are

Money Supply CU - currency held by household and firms D - Deposits held by HF M - Money Supply H - Monetary Base RE - Reserves of Charted bank. These are the currency held by chartered banks plus the deposits of chartered banks at the central bank. rD - reserves to deposit ratio c - currency to deposit ratio rD = RE/D < 1 c = CU/D < 1 M = {(c + 1) / (c + rD) * H } m m > 1 We now want to study how the central bank can affect H and therefore M To do this we need to understand

Laboratory report Aluminum Copper Alloy MSCI 300 – Thermodynamics of Materials Alexandre de Freitas Silveira Eau Claire December 18th‚ 2012. Abstract: At this experiment‚ the composition of an alloy of Aluminum Copper was analyzed via X-Ray Fluorescence. From this‚ it was possible to construct a phase diagram a make some predictions about the possible phases presents at considering the 3 samples used in this experiment‚ the samples prepared at this experiment the sample as delivered

The essence of psychopathy is characterized as a personality disorder that affects the normal cognition and the prospective features of the brain. This abnormality has been shown to produce: lack of empathy (including guilt)‚ shallow affect‚ consistent manipulation of others in addition to premeditated violent antisocial behaviour (Brook‚ Brieman‚ & Kosson‚ 2013; Ly et al.‚ 2012; Viding‚ McCrory‚ & Seara-Cardoso‚ 2014). Psychopaths are unpredictable; their inability to anticipate or comprehend the

Copper Cycle Summary During the copper cycle lab‚ my partners and I performed a series of reactions on copper powder and observed the changes it underwent. For the first step‚ we mixed nitric acid and copper powder‚ and noticed that a yellowish brown gas emerged‚ along with effervescence. The red solid disappeared and became a blue liquid. We know that we produced copper nitrate‚ nitrate gas‚ and water because the only two blue solutions in “A New Language” are copper sulfate and copper nitrate

and dark brown. Hair distributed in four ranges of melanin concentration (the numerical estimate of color) showed no signif icant differences for concentration of Zn and Cu but showed a significantly higher (P < 0.01) concentration for Zn:Cu in black hair than in the other color groups. Correla tion between mineral content (Zn and Cu) and melanin was low and nonsignificant except for Zn in hair color ranging from 0-100 melanin units (r = - 0.34‚ P < 0.05). Discussion of these findings is presented regarding
