1. Passive steel wires were activated in a bath (Bath A) containing 70 v. per cent HNO(3) (in which they undergo prompt repassivation), and immediately transferred to a second bath (Bath B) containing HNO(3) of a concentration varying in different experiments. After varying intervals in this bath they were transferred while still passive to a third bath (Bath C) containing strong HNO(3) (70 or ...

OBJECTIVE The objective of this study was to quantify and characterize the role of bath seats in infant mortality from bathtub drowning. METHOD Risk analysis of bathtub drowning deaths for infants aged 6-10 months was performed using data available from the US Consumer Product Safety Commission (CPSC), birth and mortality data from the National Center for Health Statistics (NCHS) for US resid...

New copper plating bath chemisties are being developed to meet the emerging need of plating copper into submicron features on semiconductor wafers. These chemistries are designed to provide a fast, efficient, fill for even the most challenging wafer terrain. It has been found that maintaining the concentration of the additives in these plating baths at certain levels is critical to the performa...

Carbonic Bath: The bath is prepared by saturating normal or mineral water with carbon dioxid (CO2). The effect of the bath depends on its temperature and on the amount of CO2 in the water. The bath should be hypothermic (28°C – 34°C). The bath is more efficient at lower temperature. An active hyperemia arises in the places where the skin is in a contact with the bath. Capillaries dilate there a...

The microscopic approach quantum dissipation process presented by Yu and Sun [Phys. is developed to analyze the wave function structure of dynamic evolution of a typical dissipative system, a single mode boson soaked in a bath of many bosons. In this paper, the wave function of total system is explicitly obtained as a product of two components of the system and the bath in the coherent state re...
