A method of reducing pollutants exhausted into the atmosphere from the combustion of fossil fuels. The disclosed process removes nitrogen from air for combustion, separates the solid combustion products from the gases and vapors and can capture the entire vapor / gas stream for sequestration leaving near-zero emissions. The invention produces up to three captured material streams. The first stream is contaminant-laden water containing SOx, residual NOx particulates and particulate-bound Hg and other trace contaminants. The second stream can be a low-volume flue gas stream containing N2 and O2 if CO2 purification is needed. The final product stream is a mixture comprising predominantly CO2 with smaller amounts of H2O, Ar, N2, O2, SOX, NOX, Hg, and other trace gases.

The invention discloses a high-efficiency oil sludge pyrolysis oil making method and system and belongs to the technical field of solid waste recycling and environment. Crude oil sludge is subjected to deep drying and breaking treatment by virtue of a two-stage blade-type dryer and then enters a spiral pyrolyzing furnace, and produced pyrolysis gas is subjected to spray cooling to obtain an oil product; noncondensing gas and part of pyrolysis oil which are produced in a drying and pyrolysis process are fed into a burning furnace to be burned, and high temperature smoke produced during burning is used for providing heat for a pyrolysis furnace; smoke at an outlet of a jacket of the pyrolysis furnace passes through a heat conduction oil heat exchanger to recycle waste heat and then is discharged into the air; and the heat conduction oil after being heated provides heat for the blade-type dryer. Therefore, the high-efficiency oil sludge pyrolysis oil making method and system are safe and reliable, drying pyrolysis efficiency is high, the oil product in the sludge can be recycled, gradient utilization of energy is realized, and oil sludge recycling and harmless treatment is realized.

A bi-directional system for actively deflecting the distal tip of a catheter includes a reconfigurable tube that is positioned proximal to the catheter's distal tip. The tube is formed with slits that are arranged to allow the tube to be transformed from a relaxed, cylindrical configuration to a plurality of deflected configurations. First and second pull wires are provided, with each wire having a respective distal end that is attached to the distal end of the tube. Each wire extends to a catheter handle where it is attached to a respective reel. The reels can be rotated, back and forth, to selectively deflect or relax the tube. To ensure a smooth recovery after a relatively large deflection, a mechanism is disclosed for delaying an application of tension on one of the pull wires until at least a portion of any tension on the other pull wire is released.

A fuel cell stack (7) has a two-pass fuel flow field (11, 14) extending from a fuel inlet (8) around a fuel turnaround manifold (12) to a fuel outlet (15). The stack has two air flow fields (37, 40) extending from an air inlet (32) through an air turnaround manifold (38) to an air outlet (41), the air outlet (41) being adjacent to the fuel outlet (15). The stack includes a coolant flow field (23, 25, 27) which extends from a coolant inlet (21) to a coolant outlet (28), the coolant inlet being adjacent to both the fuel outlet and the air outlet. The fluid flow configuration provides lower temperature, a more even temperature profile, a higher coolant exit temperature, and permits operation with higher air utilization and lower coolant flow.

The present invention is directed to a non-human mammal with at least 30% of all of its glial cells in its corpus callosum being human glial cells and / or at least 5% of all of its glial cells in the white matter of its brain and / or brain stem being human glial cells. Methods of producing and using the non-human mammal are also disclosed.

Energy is recovered during the production of aromatic carboxylic acids by liquid phase oxidation of aromatic hydrocarbons by performing a high efficiency separation on the reactor overhead vapor to form a high pressure gaseous overhead stream comprising water and organic impurities; recovering heat energy from the high pressure gaseous overhead stream by exchanging heat with a suitable heat sink material such that a condensate comprising from about 20 wt % to about 60 wt % of the water present in the high pressure gaseous overhead stream is formed and a high pressure off-gas is formed; and recovering energy in the form of work from the high pressure off-gas. Preferably such work is recovered using isentropic means for energy recovery, for example an expander. Apparatus for such process is also provided.

The invention discloses a method for preparing sulphuric acid by economically recovering sulfur dioxide in low-concentration or noncontinuous flue gas, which comprises that: the flue gas containing the sulfur dioxide is subjected to purification, dust and impurity removal, temperature reduction, and acid mist removal, and then divided into two paths; one path of the flue gas is sent to a desulfurization working section, high-purity SO2 gas generated after absorption and desorption of the flue gas is evenly mixed into the other path of flue gas which is not subjected to desulfurization, the SO2 concentration of the mixed flue gas is improved to be more than 5 percent, and the mixed flue gas enters a single-conversion single-absorption acid preparation working section; and tail gas after acid preparation enters the desulfurization working section again for desulfurization, and is discharged after the SO2 content is far lower than the discharge standard. The process changes smelter off-gas which cannot meet the requirement of preparing acid by a contact method originally into the flue gas which can prepare the acid normally, and does not need desulfurizing all the flue gas, so the method greatly reduces energy consumption, running cost and investment, and the discharge amount of SO2 is far lower than that of a conventional flow so as to solve a difficult environmental protection problem for partial non-ferrous metallurgical plants and accord with the policy of national energy saving, energy consumption and pollution reduction.

The present invention relates to a high sensitivity crime scene swab device for maximal recovery of trace forensic DNA evidence left at a crime scene for DNA PCR analysis.

An in-situ method and apparatus for recovering hydrocarbons from hydrocarbon-bearing material by dissociation includes sinking a well casing into a deposit of the hydrocarbon-bearing material. A probe is inserted into the well casing until the probe end is adjacent the deposit of material. An electrical charge is released into the deposit via the probe end to dissociate the hydrocarbon-bearing material and produce a hydrocarbon rich product which can be recovered for fuel value.
