    Notes: A patient with coexisting dermal cylindromas (Turban tumour), eccrine spiradenomas and a variant of basal cell adenoma of the parotid gland characterized by prominent local deposition of hyaline (membranous basal cell adenoma of parotid gland) is reported. The microscopic appearance of the cutaneous and parotid gland tumours was very similar. This rare association of analogous tumours of sweat and parotid glands has been described only in 5 previous cases. It is hypothesized that the occurrence of the 3 different tumours found in this individual may be explained by the multipotential reserve cell concept and these tumours perhaps could be considered as different expressions of a single genetic disorder.

    Notes: Abstract The impact of a flood control, low flow argumentation reservoir in the Midwestern part of the United States on BOD, COD, and ammonia was evaluated in this paper. Fifteen years of weekly water quality data (9 yr before impoundment and 6 yr after impoundment) from four sampling stations upstream and downstream of the reservoir were available for analysis. The annual loading rates of these parameters (kg ha−1 vr−1) were found to correlate well with annual runoff (cm yr−1). Besides, the reservoir was found to have had a significant and beneficial impact on the downstream loading rates of BOD and COD, which were reduced by 55 and 75%, respectively. As for ammonia, the results of this study indicate that its annual loadings at downstream locations were not significantly affected by the reservoir. Average non-point source contributions of BOD and ammonia loadings into the system were found to be about 80 and 55%, respectively.

    Notes: Abstract This paper presents an analysis of the impact of a flood control reservoir on the downstream concentrations and loadings of nitrite plus nitrate N and orthophosphate (soluble nutrients). Fifteen years of weekly sampling data (9 yr before impoundment and 6 yr thereafter) from four sampling stations were analyzed. The results indicate an increase in the annual average concentrations of nitrite plus nitrate N. These increases varied from 4 to 34%. The changes in orthophosphate concentrations were more modest. Annual loading rates of both parameters (kg ha−1 yr−1) correlated well with runoff (cm yr−1). A comparison of the leading rate correlations for all four sampling stations showed that the differences between them are not significant at the 95% level of confidence. Besides, the reservoir was shown to have had no significant impact on the average annual loading rates of these two soluble parameters at downstream locations.

    Notes: Abstract Both qualitative and quantitative approaches were used to evaluate the impact of a flood control, low flow augmentation reservoir on seven water quality parameters: Suspended solids and total phosphate (particulate parameters); BOD, COD, and ammonia (O2-demanding parameters); and orthophosphate and nitrite plus nitrate N (soluble nutrients). Fourteen years of weekly sampling data above, in, and downstream of the reservoir both before and after the reservoir became operational were analyzed. This paper considers the effects of the reservoir on the particulate parameters. There was a dramatic decrease in both suspended solids and total phosphate concentrations in the reservoir discharges, particularly during periods of high river flows and high reservoir inflow parameter concentrations. At all sampling stations, the annual parameter loading rates (kg ha−1 yr−1) correlated linearly with annual runoff (cm yr−1). The suspended solids removal efficiency of the reservoir was dependent on annual runoff and averaged about 90%. Non-point source contributions of suspended solids were well over 99% when annual runoff exceeded 6.57 cm y−1 and over 95% even when annual runoff was as low as 1.63 cm yr−1
