The inspection of pipelines, especially those of non-man-entry size, is a particularly difficult job since the sections to be inspected extend usually over long distances and are typically laid underground. Technical installations such as photography or direct inspection with the aid of endoscopes or television cameras are in principal suitable for that purpose. Towards the end of 1987, the development of a novel television system especially well-suited for use in pressurized drinking water pipelines was completed in Germany in close cooperation with the Berliner Wasser-Betriebe. Since the summer of 1988, two camera dollies and two colour television cameras are at the disposal of the Berliner Wasser-Betriebe. The television camera is linked to a vehicle via a 200-m long cable, wound on a cable drum. The vehicle itself is fitted with several colour and monochrome monitors, a PC complete with printer, a videorecorder for recording, and holding fixtures for two reflex cameras. The monitor of the PC is, in addition, used on a leakage detector that operates in accordance with the correlation method and which is also located in the vehicle. The correlation device can, moreover, also be used as mobile equipment outside the vehicle for use on any desired location. A small portable black-and-white camera with monitor is also available for use outside the vehicle.

Start Page 231 Other Pages 246 Notes Place of Publication ISSN/ISBN 0049-6979 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract Red alder (Alnus rubra Bong.) is well recognized as an effective host plant for the symbiotic fixation of N. While this fixation process leads to the rapid accumulation of N within the ecosystem, it also enhances nutrient accumulation in biomass and soil organic matter and increases nitrification and cation leaching. We hypothesized that changes in soil properties resulting from these processes would decrease site productivity for second rotation red alder. Adjacent stands of 55 yr old alder and Douglas fir (Pseudotsuga menziesii [Mirb.] Franco) were studied at the Thompson Research Center on the Cedar River Watershed in western Washington, USA. The presence of red alder caused the following soil changes: decreased soil solution pH, increased CEC, increased exchangeable acidity accompanied by a decreased soil pH and base saturation. This decreased soil and soil solution pH resulted in increased Al concentration in the soil solution and on exchange sites as well as decreased P availability. To determine the effect of these changes on the productivity of the 2nd rotation alder forest, a species conversion experiment was initiated 5 yr ago. Results from this conversion study clearly indicated that the first rotation red alder forest has caused a relative decrease in the productivity of the second rotation red alder plantation. Compared to the growth of red alder on the former Douglas fir site, the second rotation red alder on the former red alder site exhibited 33% less height growth and 75% less aboveground biomass accumulation after 5 yr. Future research will focus on identifying those factors causing this lower productivity including P availability, soil acidity and Al toxicity, cation availability, and competition with other vegetation.

A case of childhood lead poisoning is presented in which the only identified source of lead was lead solder from newly installed water pipes. Partly as a result of this case, the Massachusetts Board of Plumbers and Gas Fitters banned the use of 50/50 lead-tin solder or potable water lines. It is anticipated that this ban will increase the cost of new housing by only $16 per unit but will significantly reduce one environmental source of lead.

A sample taken from the public water supply, and a hot water sample (80 degrees C) collected from hot water tanks, did not yield legionellas. Legionella pneumophila serogroup 3 was found in samples taken at the first point of mixed hot and cold water (50 degrees C) at 3 X 10(2) cfu l-1. 12 of 26 samples from the shower-heads yielded 10(3) to 2.5 X 10(5) cfu l-1 and one of 12 water samples from oxygen bubble humidifiers tested yielded 1.6 X 10(4) cfu l-1. No other legionellas species or serogroups of Legionella pneumophila were isolated during the study. No cases of nosocomial pneumonia were detected among 3653 patients' records, nor was there serological evidence of Legionella infection in the 180 patients tested.

For concentrations of between 20 and 300 nl litre-1 there were linear relationships between exposure concentration and O3 uptake rates. Increasing photon flux densities increased rates of photosynthesis and transpiration, the increases being larger in actively growing than dormant seedlings. Physiological condition (dormancy or active growth), species and photo flux density were found in influence O3 flux via their effects on stomatal conductance. Exposure to 80 nl litre-1 O3 resulted in consistent increases of stomatal conductance and there were also indications that water-use efficiency was decreased.

Pub Date Free Form 1989/ Volume 16 Issue 5 Start Page 511 Other Pages 521 Notes Place of Publication ISSN/ISBN 0271-3586 Accession Number Language SubFile DOI Output Language Unknown(0) PMID Abstract We studied the relation of radon exposure and tobacco use to lung cancer among tin miners in Yunnan Province in the People's Republic of China. Interviews were conducted in 1985 with 107 living tin miners with lung cancer and an equal number of age-matched controls from among tin miners without lung cancer to obtain information on lung cancer risk factors including a detailed history of employment and tobacco use. Occupational history was combined with extensive industrial hygiene data to estimate cumulative working level months (WLM) of radon daughter exposure. Similar data were also used to estimate arsenic exposure for control in the analysis. Results indicate an increased risk of lung cancer for water pipe smoking, a traditional form of tobacco use practiced in 91% of cases and 85% of controls. Ever use of water pipes was associated with a twofold elevation in risk when compared with tobacco abstainers, and a dose-response relation was observed with increasing categories of pipe-year (dose times duration) usage. Estimated WLM of radon exposure varied from 0 to 1,761 among subjects but averaged 515 in cases versus only 244 in controls. Analyses indicated that the persons in the highest quarter of the radon exposure distribution had an odds ratio (OR) = 9.5 (95% confidence interval = 2.7-33.1) compared to persons without radon exposure after controlling for arsenic exposure and other potential confounders. Examination of duration and rate of radon exposure indicated higher risk associated with long duration as opposed to high rate of exposure. Cross-categorizations of radon exposure and tobacco use suggest greater risk associated with radon exposure than tobacco in these workers.

Both mean Hb and HCT values were found to be significantly higher in sheesha smokers of all age groups p<0.001], heavy cigarette smokers aged 40 to 49 years p<0.05] and light plus heavy cigarette smokers aged 50-65 years. Carboxyhaemoglobin levels were higher in sheesha than cigarette smokers. Positive correlations were found between COHb levels and that of HCTvalues in both sheesha and cigarette smokers. In seven out of twelve sheesha smokers investigated, the red cell mass was normal while Plasma volume was decreased in ten subjects. It seems that relative rather than absolute polycythaemia is the rule in sheesha smokers.

The technique showed that Legionella pneumophila 1st serogroup seropositive reaction was traced among the healthy workers in 0.2% (antibody titer 1:64). Rather high percentage (7.1%) of persons with specific antibodies was found among those who had suffered the fever disease 6 month before the examination. Among 191 fever patients examined, in 35 (18.3%) cases antibodies against L. pneumophila were detected in diagnostic titers. In 26 workers legionellosis was diagnosed as a result of serologic testing, and Pontiac fever cases were predominant. 1 case was subsequently followed by pneumonia. A chronic nature of epidemic manifestations of legionellosis was established. The pathogenic antigen was detected in 4 of 32 water samples taken from the factory water pipes.

Nine bonding procedures, each involving 18 extracted human maxillary permanent canines, were used. Ground enamel surfaces were etched with a 37% H3PO4 solution, a 15% H3PO4 gel, or a 5% H3PO4 solution for 60, 30, and 15 seconds, respectively. Cylinders of an orthodontic bonding resin, Concise, were prepared in a special device. The test specimens were disassembled 15 minutes after preparation and stored in distilled water at 37 degrees C for 24 hours. A shear load was applied to the bonded cylinders at a crosshead speed of 0.02 in.min-1 in an Instron testing machine, and the shear bond strengths were calculated and expressed in MN.m-2. A two-factor analysis of the data showed that the H3PO4 concentration had no significant effect on the shear bond strength, but the duration of etching affected shear bond strength significantly. The enamel aspects of the fractured test specimens were examined microscopically and the percent failure within the bonding resin at the bonding sites estimated. The correlation between shear bond strength and percentage failure within the bonding resin was not significant. The effects of the nine etching procedures on ground and unground enamel surfaces were studied by scanning electron microscopy. The etching procedures produced well-defined etching patterns on both ground and unground enamel surfaces.
