Twenty-six thick film inks from two vendors have been approved for hybrid microcircuit (HMC) production use. A data base of chemical information was established for all the inks to aid in future diagnostic and failure analysis activities. Efforts included both organic chemical analysis of printing vehicles and binders and inorganic chemical analysis of glass frits and ...
Velocity-modulation spectroscopy is an established technique for performing laser absorption spectroscopy of molecular ions in a discharge. However, such experiments are often plagued by a coherent background signal arising from emission from the discharge or from electronic pickup. Fluctuations in the background ...

The newly developed technique of polarization pulse shaping is applied to the control of two-photon absorption in atomic rubidium. This technique enables the manipulation of the transient vector properties of a light matter interaction. We establish that control can be exerted on the angular distribution of the final state, and demonstrate the ability to ...

The spectra of anhydrous uranyl nitrate in organic solvents were investigated in the range from 360 to 500 m mu . The spectra retained their vibrational character in all investigated solvents and do not differ markedly from those of the sesquihydrate and other hydrates. The appearance of 10 absorption bands in the range 20,000 to 28,000 cm/sup -1/ was ...
Zinc protoporphyrin is the predominant fluorescent porphyrin accumulating in erythocytes as a result of chronic lead absorption or iron-deficiency anemia. Although diagnostic concentrations or thresholds for it in erythocytes have been inferred, normal adult averages have not been established. We quantitatively assessed average zinc protoporphyrin values ...
