Meatal strictures may be due to ammoniacal
dermatitis in the very young, lichen sclerosus (LS) in the adolescent and young adults and instrumentation or poor hygiene at any age.
Samples were analyzed for total suspended solids (TSS), biochemical oxygen demand (BOD5) and ammoniacal
The average pH, total ammoniacal
nitrogen (TAN = N[H.sub.3]+N[H.sub.4.sup.+]), DM and VS content of the mesophilic inoculum obtained was 8.01, 3.29g/kg, 3.98% (of total mass) and 63.9% (of DM), respectively.
The results of the analyses involving total nitrogen, total phosphorus, total ammoniacal
nitrogen, orthophosphate, pH, dissolved oxygen, % of [O.sub.2] saturation, water temperature and chlorophyll a were submitted to multi-variation analyses considering the Principal Components Analysis (GOODALL, 1954 apud VALENTIN, 2000).

thiosulfate solutions, Hydrometallurgy 66, 67-76 (2002).
Approximately 0.5 L of each water sample was filtered in a Whatman GF/C glass fibre filter (porosity 0.45 mm, diameter 47 mm), for determination of the concentrations of suspended particulate matter (SPM) (APHA, 1998), chlorophyll-a (Nush, 1980), ammoniacal
nitrogen (N-ammoniacal) (Koroleff, 1976), dissolved Kjeldahl nitrogen (DKN), N-nitrate (N-N[O.sub.3]), N-nitrite (N-N[O.sub.2]) (Mackereth et al., 1978), dissolved phosphorus (DP), and P-orthophosphate (P-P[O.sub.4]) (Golterman et al., 1978).
Ammonia volatilisation is controlled by wind speed, temperature, and ammoniacal
N concentration and pH in the surface soil (Sherlock et al.
This synthesis occurred in ammoniacal
medium under vigorous stirring and at high pH.
([MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII]), nitrate ([MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII]), and nitrite ([MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII]) nitrogen concentrations in the surface-applied effluent and drainage leachate were monitored regularly.
These include hydrometallurgy in sulphate, chloride and ammoniacal
for her dedicated work on the measurement of ammoniacal
nitrogen and soluble calcium and magnesium as well as her contributions to the technical committees of the American Foundrymen's Society, Inc.
For both wastes, a sample of approximately 1 L was collected in each box for characterization (dry matter and contents of total N and ammoniacal
N), according to the methodology proposed by Tedesco et al.
