This month's installment completes our primer series on magnetic fields by defining conditions where remedial EM site shielding is in fact technically feasible and by illustrating examples of both passive and active shielding methods (or attaining lower site fields. For those readers who may have missed one or more previous articles, we have thus far presented some basic physics describing magnetic source fields [Microscopy Today, November, 1995), examined magnetic survey equipment and methods relevant to EM interference thresholds (Ml, January, 1996), and, in Part IV (“Survey Data Analysis”, MT, May, 1996), suggested techniques for interpretation of typical EM site survey data.

Aluminum Alloy Anode

The Na2SnO3 and H-N-R inhibitors effects on the high active aluminum alloy in alkaline solution (805mol/LNaOH) have been systematically studied by hydrogen collection and electrochemical measurement in the present investigation. The results showed that the hydrogen evolution rate was low at the value of 0.404 mL/ (min·cm2) in alkaline solution with 0.01mol/L Na2SnO3, but the electrode potential was only -1.515Vvs.SCE and it moved to the positive direction seriously; When adding 10wtH-N-R and 0.01mol/LNa2SnO3 into the alkaline solution simultaneously, the aluminum alloy anode had a lower hydrogen evolution rate of 0.342mL/ (min·cm2) and a more negative electrode potential of -1.591Vvs.SCE. The electrochemical performance of aluminum alloy anode has been improved greatly by the cooperation of H-N-R and Na2SnO3.

Detection Probabilities

Assessment of the efficacy of survey techniques for determining species occurrence is crucial for the validation of wildlife survey data. We analysed repeated site-survey data for adults and larvae of the growling grass frog (Litoria raniformis) in order to estimate probabilities of detection for the species using alternative survey techniques. The estimated probability of detecting adults of L. raniformis at occupied sites using diurnal searches was much less than 1.0 (0.107; 95% credible interval: 0.045, 0.192). The estimated probability of detecting adults using nocturnal spotlight searches was considerably higher, but still less than 1.0 (0.696; 95% credible interval: 0.585, 0.796). These results indicate that nocturnal searches are a much more efficient and reliable means of detecting the presence of adult L. raniformis than diurnal searches, but detection using either technique is less than certain. The probability of detecting tadpoles of L. raniformis using either funnel-trapping or dip-netting techniques was estimated at 0.350 (95% credible interval: 0.151, 0.567). Together, these results indicate that reliance on single-site visits during surveys for this species is likely to result in severe under-estimation of the proportion of sites that are actually occupied. We urge other workers to use repeated site-survey data and appropriate methods of data analysis to assess and report probabilities of detection when documenting the results of wildlife surveys.

Rolling Technology

The effect of rolling technology on the microstructure, electrochemical property and anti-corrosion property of Al-Mg-Sn-Bi-Ga-In alloy anode in alkaline solution (80°C, Na2SnO3 + 5mol/L NaOH) has been analyzed according to the chronopotentiometry (E-T curves), hydrogen collection tests and modern microstructure analysis. The results show that when controlling the pass deformation at 40%, with the increase of rolling temperature, both electrochemical activity and anti-corrosion property of Al anode increase first and then decrease. When the rolling temperature is 420°C, the aluminum alloy anode has the most negative electrode potential of about -1.521V (vs.Hg/HgO) and the lowest hydrogen evolution rate of 0.1716mL/ (min•cm2). The optimum comprehensive performance of Al alloy anode has been obtained.
