The Presence of Iron in Surface Waters
Iron is found in most natural surface waters, although in widely varying amounts, depending on several factors relating to the water and its environment. This report is designed primarily to gain an understanding of these factors contributing to the stability and solubility of iron in these natural waters
Calcium Carbonate Determinations
Calcium compounds are abundant in nature. The carbonate ion may exist in many varieties, such as aragonite and limestone. Of major importance in the following discussion, however, is calcite. Calcium carbonate may well be of animal origin, prime examples being sea shells, coral, and chalk. Dolomite, on the other hand, is a double carbonate of calcium and magnesium. Calcium in natural waters exists mainly as a bicarbonate, Ca(HCO3)2, which is temporary hardness, or as a sulfate, which is permanent hardness.
From determinations made periodically (every two weeks) since August 1966, a decrease has been found in the calcium content as the water progresses downstream. There are two possible explanations for this: 1. Dilution by tributaries, or 2. Saturation and precipitation of calcium carbonate from the water
Self-reports of sexual attraction change in a sample of male psychotherapy consumers in a private practice setting
The purpose of this study was to see if clients in a private practice therapy setting reported any changes in how they rated their sexual attraction, their stated goal. The therapy was conducted weekly, lasting at least one year. The sample was comprised of 30 men whose desired goal was toward a shift from same-sex attraction to opposite-sex attraction. A convenience sample from the author’s private practice, over a 5-year span, was used.  Clients were invited to complete surveys at intake, between 12-18 months into therapy, and one year afterwards. Following the format of the Klein Sexual Orientation Grid, clients were asked about sexual attraction on a measurable continuum. A repeated-measures analysis of variance (ANOVA) was used to test the differences between the pre, mid, and post responses. In this sample, at 1 year post-discharge, 10% reported their sexual attraction as “for the other sex somewhat” vs. 0 % at baseline; 17% reported their sexual attraction as “for the other sex mostly” vs. 0 % at baseline; and 23% reported their sexual attraction was “for the other sex only” vs. 0 % at baseline. These outcomes proved statistically significant changes from baseline compared to follow up.  Despite the study’s limitations, significant sexual attraction shifts from same-sex to opposite-sex were self-reported in a highly motivated clinical sample of men
