 564  511. Measurable electrical parameters are monitored during the weld power pulse. Experience with this method of in-process monitoring has demonstrated that electrical parameters and weld strength have a fair degree of correlation. Normally, excess transverse wire is trimmed at the rail weld points. However, the machine will leave the wire projecting beyond the rail where an input connection to the module is needed. Transverse wires can also be omitted at points where the matrix is to be folded. 512. The mean volume of urine was 1.0 ml per pair of mice versus 0.8 ml for the untreated controls. Urinary nitrogen content was 10.7 mg nitrogen per mouse for animals given diuril and 12.5 mg for those given no diuretic. Animals similarly pretreated with another compound, aminophylline (2 mg orally) were then given endotoxin and ACTH and showed change neither in urine volume (1.2 ml) nor nitrogen output (14.6 mg). 513. It is worthwhile pointing out that a self-contained iner-tial system may be the only way in which to control the launch phase from the Moon on a return journey to Earth. This is likely to be the case at least for the early manned expeditions before adequate ground radio stations can be erected on the Moon. 514. Sections treated first with heat-inactivated or chelated guinea pig serum and then with conjugated anti-gpC showed no fluorescence or only occasional mere traces of fluorescence in glomerular capillary walls. Sections treated with conjugated anti-gpC alone showed no yellow-green fluorescence. The latter control indicated absence of any crossreaction of the anti-gpC with constituents of human serum. 515. Carbon contents in different heats varied from about 0.05% to 0.1%. This carbon variation can be attributed to the melting and casting technique, or to carbon adhering to remelt scrap which may have been charged in the crucible. No significant differences in other impurity contents were apparent. It is not now known whether the impurities have affected the mechanical properties of the alloys. 516. Forty-six per cent of those patients receiving 1.0 gm. of cycloserine daily converted their sputum within 6 months, while only 26% of those receiving 0.5 gm. daily did so. Another study dealt with the use of kanamycin in 3 groups of patients. The first group consisted of 22 patients whose tuberculosis was far advanced and who had failed to respond to other regimens. 564 |
