The hospital market for water distillation equipment

Thesis (M.B.A.)--Boston UniversityThe purpose of this paper is to partly fill the information void which exists with respect to one of these small but vital industries, the water distilling equipment industry. Rather than cover all of the aspects el the select in a limited manner, the writer has chosen to describe in detail the majer area of interest Of the industry, namely, the hospital market. There is currently a virtually complete absence of published data on the industry. This paper is a detailed treatment of the extent and nature of the market for the two majer types of water distilling equipment (water stills and tanks) among hospitals with new construction. To the best of the writer's knowledge, most of the information in this paper has never before been published

The investigation of some water--carbohydrate and water--polyhydroxyalcohol systems utilizing the enthalpy of transfer of some slightly soluble salts as a structural probe

The investigation of nonelectrolyte-water interactions with respect to structure has been studied. An indirect method was used to determine some of the structural properties of these nonelectrolyte-water systems, since no direct method exists for these determinations. A titration calorimeter was used to collect thermodynamic data on the solute-water interactions at 25°. The enthalpy of transfer of sparingly soluble salts from pure water to water-nonelectrolyte solutions was used as the probe because it utilizes two structure sensitive probes instead of just one, as has been customarily used in this type of investigation. This method utilizes the heat of precipitation of these salts rather than the heat of solution of the ion. The groups of solutes that were studied were carbohydrates and polyhydroxyalcohols. It was found that the simple carbohydrates (glucose, sucrose, and ribose) and the polyhydroxyalcohols (sorbitol and mannitol) used in this study did not exhibit normal hydrophobic water-solute interactions but rather showed a hydrophilic nature. This was expected because of the large number of polar groups of the carbohydrates and polyhydroxy alcohols
