Improved methods of treating water and hydrocarbons producing subterranean formations to reduce the water permeabilities of the formations without substantially reducing the hydrocarbons permeabilities thereof are provided. The methods basically comprise introducing into the formation a chemical which does not resist water flow and attaches to adsorption sites on surfaces within the porosity of the formation but slowly washes off the sites as another fluid flows through the treated formation. Thereafter, a water flow resisting polymer is introduced into the formation so that it flows deeply into the porosity of the formation before the previously introduced chemical washes off and attaches to the adsorption sites as the chemical washes off.

Various methods for decreasing the amount of nitrogen oxides released to the atmosphere as a component of combustion gas mixtures are provided. The methods specifically provide for the removal of nitric oxide and nitrogen dioxide (NOx) from gas mixtures emitted from stationary combustion systems. In particular, methods for improving efficiency of nitrogen oxide reduction from combustion systems include injecting metal-containing compounds into the main combustion zone and / or the reburning zone of a combustion system. The metal containing compounds react with active combustion species, and these reactions change radical concentrations and significantly improve NOx conversion to molecular nitrogen. The metal-containing additives can be injected with the main fuel, in the main combustion zone, with secondary or reburning fuel addition, or at several locations in the main combustion zone and reburning zone. Optionally, nitrogenous reducing agents and / or overfire air can be injected downstream to further increase NOx reduction.

Provided is a methodology and system for applying coatings onto the interior surfaces of components. The approach comprises a vapor creation device (for example an electron beam or laser that evaporates a single or multiplicity of solid or liquid sources), a vacuum chamber having a moderate gas pressure (between about 10−4 to about 103 Torr) and a inert gas jet having controlled velocity and flow fields of gas jet. The gas jet is created by a rarefied, inert gas supersonic expansion through a nozzle. By controlling the carrier gas flow into a region upstream of the nozzle an upstream pressure is achieved (i.e. the gas pressure prior to its entrance into the processing chamber through the nozzle). The carrier gas flow and chamber pumping rate control the downstream (or chamber) pressure (i.e., downstream of the nozzle). The ratio of the upstream to downstream pressure along with the size and shape of the nozzle opening controls the speed of the gas entering the chamber. The carrier gas molecular weight (compared to that of the vapor) and the carrier gas speed controls its effectiveness in redirecting the vapor atoms via binary collisions towards the substrate. The speed and flux of the atoms entering the chamber, the nozzle parameters, and the operating chamber pressure can all vary leading to a wide range of accessible processing conditions. Vapor created from a source is transported into the interior regions of a component using binary collisions between the vapor and gas jet atoms. Under certain process conditions these collisions enable the vapor atoms to scatter onto the interior surfaces of the component and deposit.

The invention relates to a filter element consisting of a molded body of porous concrete, which element is arranged in the water stream of a purification system. In particular, the filter element (10) is a molded pervious concrete layer arranged as a partition between a lower compartment (9) and an upper compartment (11) of a treatment chamber (8), wherein the water inlet (12) opens into the lower compartment (9) and a water outlet (17) issues from the upper compartment (11). The pervious concrete filter layer may contain one or more additives to enhance adsorption of pollutants, such as heavy metal ions, phosphorous, hydrocarbons or other target soluble pollutants.

An ultraviolet flux multiplying air sterilization chamber comprises inner surfaces having a diffuse reflective behavior. The sterilization chamber includes an inlet aperture and an outlet aperture for air to flow through said chamber and a light source emitting an ultraviolet light. Due to the reflectivity of the inner surfaces of the chamber, a flux of the ultraviolet light is multiplied by reflecting multiple times from the inner surfaces of the chamber. The inlet and outlet apertures are advantageously configured to reduce the amount of light that escapes from the chamber and increase the amount of photons available in the chamber. In an exemplary embodiment, perforated end panels having diffuse, reflective interior surfaces may be provided over at least a portion of the inlet and outlet apertures.

A fabric and method to support garments comprising opaque heat-moldable circular knit fabrics having relatively high amounts of spandex material as well as sufficient amounts of other fibers to simultaneously provide maximum support and maximum comfort to a wearer and which can be easily molded to the specifications of a wearer's body dimensions. Such high-spandex content, moldable garment fabrics are novel to the industry since the permissible added amount of spandex within such fabrics has been limited due to the power, modulus strength, and elongation of such fibers. Furthermore, the ability to provide moldable, high-spandex circular knit fabrics has been limited, if not impossible, due to the above-noted characteristics of the spandex fibers themselves. The inventive moldable fabrics and garments provide such desirable spandex properties while also increasing the comfortability to the wearer. The method of producing such fabrics is also contemplated within this invention. Both the fabric and the method state that the amount of spandex in the fabric is at least 24% of the total fiber weight in the fabric.

An in situ soil remediation system may be used to remove or reduce levels of mercury contamination within soil. The soil remediation system may also remove or reduce levels of other contaminants within the soil. Mercury may be vaporized within the soil by a heating system. The vaporized mercury may be removed from the soil by a vacuum system. The vaporized mercury may pass through heated risers that elevate the vaporized mercury. After the vaporized mercury passes from the heated risers, the vaporized mercury may be allowed to cool, condense, and flow downward to a treatment facility. Removing mercury from the soil as a vapor may provide an economical, safe, and efficient way to remediate mercury contaminated soil.
