A method of expanding tobacco involves introducing a steam flow and a tobacco material into a duct having an inlet and an outlet and defining an arcuate flow path. The tobacco is entrained in the steam flow and conveyed along the arcuate flow path and toward the outlet. The presence of the steam results in volumetric expansion of the tobacco as the steam and entrained tobacco travel along the flow path. The steam and entrained tobacco are then collected and separated. As such, an expanded tobacco is provided.

Herein is described Nanostructure Enhanced X-ray Therapy (NEXT), which uses nanomaterials as radiosensitizers to enhance electromagnetic radiation absorption in specific cells or tissues. The nanomaterial radiosensitizers emit Auger electrons and generate radicals in response to electromagnetic radiation, which can cause localized damage to DNA or other cellular structures such as membranes. The nanomaterial radiosensitizers contain moieties for specific targeting to molecules or structures in a cell or tissue, and can be functionalized for increased stability and solubility. The nanomaterial radiosensitizers can also be used as detection agents to help in early diagnosis of disease. Together with known techniques such as Computed Tomography or Computerized Axial Tomography (CT or CAT scan), these nanomaterial radiosensitizers could allow early diagnosis and treatment of diseases such as cancer and HIV.

The invention relates to an integrated diffusion oriented combustion chamber which adopts a full ring combustion chamber structure. The integrated diffusion oriented combustion chamber mainly comprises a crankcase, a combustion liner and an oriented diffuser. The oriented diffuser realizes pneumatic and structural coupling, controls the tangential flow direction and carries out diffusion and speedreduction, and a local return low-speed zone is formed, thereby being good for flame linkage and tangential stable combustion; grading combustion is adopted, and a pre-combustion grade can be selected to work alone and work together with a main pre-combustion grade according to work conditions; the pre-combustion grade utilizes the trapped vortex combustion technology for stable work, goes into amain combustion zone to inflame a main combustion grade through a contraction outlet, and provides a stable ignition source for the main combustion grade; fuel of the main combustion grade is injected to a main combustion grade airflow in the oriented diffuser, atomization evaporation mixing with short distance is realized, and combustible mixture gas with uniform mixing is provided for the maincombustion zone. The invention allows tangential rotational flow of a gas compressor to directly go into the combustion chamber so as to realize tangential highly efficient and stable combustion; in addition, the discharge of pollutants is low, pre-rotation is provided for a turbine, the structure can be simplified, the weight is lightened, and the densification of a gas turbine is realized.

A cutting element for a drag-type drill bit comprises a cutter body having a generally cylindrical base section adapted for snug-fitting engagement in a socket of a drill bit body. The cutter body is secured to the bit body by brazing or other conventional attachment techniques. The cutter body further has a generally cylindrical cutting section integral with the base section. The cutting section has at least one inclined surface extending from a top surface of the cutting section partially along the length of the generally cylindrical cutting section. The cutter body may comprise a sintered tungsten carbide and the top surface may comprise a layer of super hard material.

A hole saw includes a depth stop for limiting the depth of penetration of the hole saw into a workpiece. The blade of the hole saw includes a plurality of slots, one of which is used to receive the depth stop. The depth stop is mounted to the blade by positioning a portion of the depth stop within the slot and sliding the depth stop from an unsecured position to a secured position. Once in the secured position, a locking member is moved within the depth stop to secure the depth stop in place. In use, the blade is advanced through the workpiece until the depth stop contacts the proximal surface of the workpiece.

A mechanical broadhead for attachment to an arrow having a broadhead body including a plurality of blade windows formed therein, a geometrically angled retractable blade attached within each of the blade windows, retaining springs for retaining the blades in a retracted position during flight, a front body slidably mounted onto the broadhead body, and a front tip secured to the front body. Upon contact with a target, the front tip and front body slide rearwardly into an end of the geometrically angled blades, thus pushing each of the blades through the blade windows into a deployed position. The blades of the broadhead are reset by inserting a sharp point underneath an end portion of the retaining springs and applying a slight twisting motion allowing the blades to retract back into the broadhead body into a loaded position.

A photo-chemically activated micro-bubble based root canal disinfection method for disinfecting a shaped root canal comprises (a) introducing a photoactive solution into the root canal, the photoactive solution containing a photoactive compound (such as methylene blue) dissolved in an alcohol carrier solution (such as polyethylene glycol and/or ethanol); (b) removing excess photoactive solution from the root canal; (c) introducing a micro-bubble solution comprised of an oxygen carrier (such as perfluorocarbon), an oxidizing agent (such as hydrogen peroxide) and a surfactant (such as a nonionic polyoxyethylene surfactant); (d) sonically or ultrasonically activating the micro-bubble solution in the canal; and (e) introducing light into the canal.

The invention is directed to stable and labile crosslinked water swellable polymeric microparticles that can be further gelled, methods for making same, and their various uses in the hygiene and medical arts, gel electrophoresis, packaging, agriculture, the cable industry, information technology, in the food industry, papermaking, use as flocculation aids, and the like. More particularly, the invention relates to a composition comprising expandable polymeric microparticles having labile crosslinkers and stable crosslinkers, said microparticle mixed with a fluid and an unreacted tertiary crosslinker comprising PEI or other polyamine based tertiary crosslinker that is capable of further crosslinking the microparticle on degradation of the labile crosslinker and swelling of the particle, so as to form a stable gel. A particularly important use is as an injection fluid in petroleum production, where the expandable polymeric microparticles are injected into a well and when the heat and/or pH of the well cause degradation of the labile crosslinker and when the microparticle expands, the tertiary crosslinker crosslinks the polymer to form a stable gel, thus diverting water to lower permeability regions and improving oil recovery.
