摘要： A method of selectively heating targeted cells within a specimen while avoiding heating of non-targeted cells is provided. The method comprises the steps of: (a) determining at least one combination of magnetic field strength and radio wave frequency (strength-frequency combination) at which only the targeted cells will resonate when the magnetic field and the electromagnetic radiation are applied to the specimen orthogonal to one another; and (b) applying a magnetic field and a radio frequency wave to the targeted cells, the strength of the magnetic field and the frequency of the radio wave corresponding to the strength-frequency combination to the targeted cells, in order to cause nuclear magnetic resonance in the targeted cells, thereby increasing the temperature of only the targeted cells.

摘要： The present invention provides an enzymatically active composition for suppressing sulfide generation. The composition is free from sulfur dehydrogenase and comprises at least one enzyme having sufficient sulfide-production inhibiting activity in an acidic medium to at least inhibit biogenic sulfide production, and an oxidized nitrogenous inorganic salt present in an amount sufficient to act as an electron acceptor for the enzyme. The oxidized nitrogenous inorganic salt preferably is selected from an alkali metal nitrite, an alkaline earth metal nitrite, an alkali metal nitrate, an alkaline earth metal nitrate, or a mixture of two or more of the foregoing salts. The enzymatically active composition is free from viable bacteria and is non-toxic (i.e., has an oral LD50 in rats greater than 1000 mg/Kg of body weight at a concentration of about 25,000 parts per million (ppm) in water). The compositions of the present invention are useful for treating and removing biofilms, as well as inhibiting sulfide production in a variety of aqueous systems.

The liquid phase LCPs have polyiminoborane, polyaminoborane, and/or borozine polymer backbone molecules, with silicon and/or phosphorous side chain molecules linked to the backbone that provide a degree of alignment assigned an Order Parameter (S), defined as S=⅓ [3 cos2 θ−1], where θ is the angle between the axis of an LCP molecule and the vertical direction. The inventive liquid phase LCPs have an average Order Parameter in the range of about 0.2 to about 0.99 and are applicable to a number of rinse, coolant, lubricant, sterilization and other protectant processes.

摘要： Dual interrelated distillation columns are disclosed wherein the heat for a first column is transferred by thermal conduction through a common wall or surface to a second column to increase efficiency and decrease waste of energy. In one embodiment, the first heat generating column is a cylindrical column, and the second column is an annular column concentric to the first column. This concentric arrangement permits the heat generated in the first column to flow outwardly into the second column, thereby improving its efficiency and reducing the heat loss. Typically, the inner first column is a high pressure rectifying column, and the outer concentric column is a stripping column. In an alternate embodiment, the inner column can simply be a portion of a high pressure distillation process, and the outer column is a portion of a lower pressure distillation column. In alternate embodiments, the rectifying apparatus can assume a variety of shapes such as a plurality of packed tubes which extend through the stripping column or a corrugated configuration or rectangular configuration as desired.

摘要： Acidic metal-bearing wastewaters are treated to produce a finished water of sufficient purity to meet discharge standards while recovering metals removed in forms which are commercially valuable. The metals are selectively precipitated, either in a batch or in a continuous system, for removal of individual metal products in a specific sequence of steps from the wastewater. In each step, the pH is adjusted to the specific pH range and sulfide ion is introduced to precipitate the metals, excepting the removal of ferric iron and aluminum which is achieved using hydroxide precipitation. Bioconversion process using unique equipment converts sulfate in the wastewater to the hydrogen sulfide gas required for the precipitation process. This bioconversion process reduces the sulfate in the wastewater so that the water can be directly discharged or used for agricultural applications.
