Bobbi Roop Advanced Photon Source Argonne National Laboratory Argonne,IL 60439 An x-ray photoemission spectroscopic study was undertaken to compare the cleaning of the Advanced Photon Source (APS) aluminum extrusion storage ring vacuum chambers after machining with and ~thout water soluble coolants. While there was significant contamination left by the coolants, the cleaning process was capable...

Mortality among 5365 members of a dry cleaning union in St. Louis, Missouri, was less than expected for all causes combined (SMR = 0.9) but slightly raised for cancer (SMR = 1.2). Among the cancers, statistically significant excesses occurred for oesophagus (SMR = 2.1) and cervix (SMR = 1.7) and non-significant excesses for larynx (SMR = 1.6), lung (SMR = 1.3), bladder (SMR = 1.7), thyroid (SMR...

OBJECTIVES To assess the knowledge and behaviour of researchers regarding criteria for authorship, and the practices of ghost and gift authorship. DESIGN Semidirective interviews of senior clinical researchers. SETTING University hospital. PARTICIPANTS Thirty-nine main investigators of clinical research programmes. MAIN MEASUREMENTS Awareness and use of International Committee of Medica...

We report on measurements of the surface acceleration for the application of dry laser cleaning. For that purpose, industrial silicon samples were irradiated by a frequency-doubled Q-switched Nd:YAG laser. The surface displacement was measured by a heterodyne interferometer and recorded by a digital storage oscilloscope. Several hundreds of shots were averaged to give smooth displacement curves...

The effect of in situ chemical oxidation (ISCO) with permanganate (MnO4-) on tetrachloroethene (PCE) in a dual permeability system consisting of low permeability clay with high permeability sand lenses was investigated by two-dimensional laboratory experiments. The experiments imitate a field remediation at a former dry cleaning facility in Denmark. Results from laboratory experiments and field...

Salvadorapersica (Miswak) is used in many parts of the world as a tool for the cleaning of teeth and general oral hygiene. This material is imported into the United Kingdom, from countries in Africa, Asia and the Middle East, and is sold in ethnic shops. They are popular amongst members of certain ethnic communities. Very little is known about the trace elements content of chewing sticks and th...

The Tagouchi method was used for providing the instruction of ultra-filter dairy membrane cleaning. The goal function with using of four undimentionalized parameter, i.e., water and milk serum flux, percent of protein and dry mass of permeate, as quality indicator of cleaning of cleaned membrane, was defined. As a result, basic cleaning solution was found as follows: 0.8% NaOH, 1.0% EDTA, 1.0% ...

The use of organic solvents in developing countries has been wide spread in the last century [1]. Organic solvents are used in different industrial processes and are sometimes considering important supplies in order to obtain more benefit in any type of manufacturer business, due to they can be reused [2]. Organic solvents are commonly used in the dry cleaning industry, because relatively stabl...

T he ban on chlorofluorocarbons (CFCs) hit users squarely in their degreasers. In the search for viable alternative cleaning processes, the first task was to determine evaluation criteria. When is a product sufficiently clean? How do we know when it’s properly rinsed? At what point is it adequately dry? After seeking out suitable non-CFC cleaning agents, we next sized up equipment best suited f...
