An apparatus and method for mixing fluids and/or solids in a manner that can be varied from maintaining the integrity of fragile molecular and biological materials in the mixing vessel to homogenizing heavy aggregate material by supplying large amounts of energy. Variation in the manner of mixing is accomplished using an electronic controller to generate signals to control the frequency and amplitude of the motor(s), which drive an unbalanced shaft assembly to produce a linear vibratory motion. The motor may be a stepper motors a linear motor or a DC continuous motor. By placing a sensor on the mixing vessel platform to provide feedback control of the mixing motor, the characteristics of agitation in the fluid or solid can be adjusted to optimize the degree of mixing and produce a high quality mixant.

A process for producing biodiesel has been invented by first extracting lipids from the sludges generated during primary and/or biological treatment of municipal, agricultural, and industrial wastewaters using primary, secondary, and tertiary treatments followed by the transesterification of the extracted lipids using transesterification conversion into alcohol-based esters. The resulting products from this process include biodiesel, glycerol, lipid-free proteins, various other useful chemicals and an aqueous-based substrate well suited for optimized digestion within subsequent biological digestion (either aerobic or anaerobic). The lipids extracted from the sludges containing high levels of microorganisms are phospholipids which can also be directly used as lecithin. The extraction of the lipids from the sludges will be performed using chemical extraction techniques with the transesterification of the extracted lipids accomplished using basic, acidic, and/or a combination of the two transesterification techniques.

The objective of the present invention is to confer pest resistance to plants of Poaceae without using any chemically synthesized pesticides. The pest resistance can be conferred to plants of Poaceae by isolating from a natural plant an endophytic bacterium capable of expressing pest resistance, artificially culturing the endophytic bacterium, and introducing the bacteria to a Poaceae plant of interest.

To alleviate the requirement to back-off all up-link performance, such as by limiting power spectral density, to overcome far-end cross-talk problems otherwise associated with relatively short loop-length wireline links, the present invention partitions the frequency spectrum based on an estimate of the loop length of a subscriber unit (CPE) modem from an exchange (LTE) modem. Up to a threshold frequency (fmax) at which received transmissions from a subscriber having a longest loop length (115) become indistinguishable by the LTE modem from a noise floor (102), up-link performance on all loop lengths is limited to correspond to that of the longest loop. At frequencies above the threshold frequency (fmax), subsets of subscribers (152-154) having relatively short loop lengths (116-119) use high frequency carriers that have signal to noise ratios sufficient to support information transmission in these elevated frequency bands.

An operation management system is provided, which includes a database (105) that accumulates operation information, including a fuel consumption amount, that is gathered from a running vehicle (A1 to B2) through a network (20); and a management device (103, 104) that sends the gathered operation information and the operation information accumulated in the database (105) to a client computer (A10, B10) through the network (20). The management device (103, 104) receives an instruction for the vehicle (A1 to B2) from the client computer (A10 and B10), and sends the received instruction to the vehicle (A1 to B2).

The methods and systems of the present invention may also be used to treat waste water from other sources, such as human waste or farm runoff from irrigation.

A method for optimizing hydraulic fracturing and refracturing simulates the geomechanical interaction between regional stress and natural fractures in a reservoir. An equivalent fracture model is created from data on the natural fracture density, regional stress and elastic properties of the reservoir, so that points in the reservoir are assigned a fracture length and fracture orientation. The horizontal differential stress and maximum principal stress direction at points in the reservoir are then estimated by meshless particle-based geomechanical simulation using the equivalent fracture model as an input. Regions in the reservoir having low differential stress based on the simulation can then be selected for initial hydraulic fracturing. Regions in the reservoir having high differential stress based on the simulation can then be selected for refracturing.

Pollution control apparatus. An exhaust aftertreatment unit is fitted to the exhaust of an internal combustion engine and a fuel reformer provides hydrogen rich gas in an optimal way to the aftertreatment unit to regenerate the aftertreatment unit. It is preferred that the hydrogen rich gas be provided only to a portion of the aftertreatment unit at any time to regenerate that portion. Stored hydrogen may be used.

Further, the machine provides the branding of the container depending on the consumer selection allowing people and consumer recognition of the product and enticing manufacturers to participate.

A method for producing a material includes providing a metallurgical powder including iron, 1.0 to 3.5 weight percent copper, and 0.3 to 0.8 weight percent carbon. At least a portion of the powder is compressed at 20 tsi to 70 tsi to provide a compact, and subsequently the compact is heated at high temperature and then cooled at a cooling rate no greater than 60° F. per minute to increase the surface hardness of the compact to no greater than RC 25. The density of at least a region of the sintered compact is increased, by a mechanical working step or otherwise, to at least 7.6 grams/cc. The sintered compact is then re-heated to high temperature and cooled at a cooling rate of at least 120° F./min. so as to increase the surface hardness of the compact to greater than RC 25, and preferably at least RC 30. Material made by the method of the invention also is disclosed.

MnO_x-containing, base-metal oxide mixtures (e.g., MnO_x—CeO₂) are useful NO_x oxidation catalyst materials and NO_x storage materials in lean-burn engine exhaust gas treatments using Lean NO_x Trap (LNT) systems. These oxidation catalyst materials are used in combination with a NO_x storage material and a NO_x reduction material. MnO_x-containing oxide mixtures can replace platinum (Pt) in LNT systems where the exhaust of the engine is repeatedly varied between a relatively long fuel-lean mode of operation and a relatively short fuel-rich mode of operation. The combination of the MnO_x oxidation catalyst, NO_x storage material, and NO_x reduction catalyst material serves to complete the oxidation of unburned hydrocarbons and carbon monoxide, and to convert NO_x to nitrogen.
