The present application is directed to the preparation of low viscosity bio-oils from the hydrothermal liquefaction (HTL) of lignocellulosic biomass in the presence of a crude glycerol and water mixture achieving a high biomass conversion ratio. The modified HTL process allows the direct use of crude glycerol as an effective solvent for biomass liquefaction creating a highly efficient and cost-effective process. Furthermore, the resulting bio-oils containing liquefied biomass, crude glycerol and water, were successfully applied as an inexpensive green substitute in the preparation of bio-based phenol formaldehyde (BPF) adhesives which retain bonding strengths (dry or wet strength) as required by ASTM standard and free formaldehyde emission levels at the F*** and F**** level according to the JIS standard.


A dual-band, dual-polarized antenna module for a mobile communication base station, which includes: a reflector plate; a radiation antenna module for transmitting and receiving two linear orthogonal polarizations in first and second frequency band, the radiation antenna module generally having a first set of radiation antenna elements operable in a first frequency band including a plurality of dipoles arranged to form generally rectangular shape, each of the dipoles substantially having a planar shape element with a convex cavity; and a second set of radiation elements operable in a second frequency band which are proximately arranged over a convex cavities in the first set of radiation antenna elements, and includes a plurality of aperture coupled patch elements generally arranged to form a quad-shape.

A bar bell comprises a plate-accepting bar that extends longitudinally between two end regions at which weight plates can be mounted, a longitudinally-extending handle positioned above the plate-accepting bar and supported by the barbell, a pair of barbell-supporting brackets positioned at respective end regions of the plate-accepting bar to stably support the barbell on a supporting surface without contact between mounted weight plates and the supporting surface, and at least one longitudinally-extending fulcrum bar affixed to the barbell in such a way that it is positioned to contact a users forearm during a bicep curl and create a lever arm vis--vis the handle that maintains the barbells center of gravity in a lagging position with respect to the users hands so as to exert enhanced resistance to the curling movement during the movement.

An audio file is transformed into a Gabor spectrogram. This is used to compare the audio file to a database of audio files, each represented as a Gabor spectrogram. Before two spectrograms are compared, they are aligned. The spectrograms are broken into blocks and individual Gabor vectors in the blocks are compared. Similarities are stored and an aggregate similarity value is derived for the block. After a series of such comparisons and shifting of the secondary spectrogram block, essentially a running window, an offset value is determined. This offset is used to align the two spectrograms at which stage the spectrograms can be compared in a more effective and meaningful manner. A set of observables is derived from the comparisons and the primary spectrogram is classified in way suitable for the application environment.

A dumbbell comprises a pair of frame members, each having a lower plate-like portion and an upper stem portion. The frame members are coupled together via spacer bars. An upper spacer bar is coupled to the frames members at the stem portions, and a handle is mounted for rotation about the upper spacer bar. Two lower spacer bars positioned near the front and back of the plate-like portions of the frame members. The frame members may provide the desired weight, either through choice of material, plate thickness or both, or the frame members may be provide a basic master weight plate for the dumbbell, with additional weight being provided by the addition of one or more weight plates to each frame member. Pads are mounted about the lower spacer bars, and are positioned to contact the wrist area of a user during exercise movements. A gap is defined between the pads through which the hand of a user may inserted to grasp the dumbbell in an upside-down orientation for secure control and comfort for certain exercise movements. The dumbbell may also be manipulated by the handle or stems for certain kettlebell exercises.

A cable attachment that permits the strap of an exercise machine to be replaced independently of the machines handle without the need for sewing machines or special tools such as crimping devices comprises a body having three juncture points arranged in a generally triangular relationship, the first point being near its top to accommodate the bodys attachment to the cable of the exercise machine, the other two juncture points lying below the first point and separated from each other by the center section of the body. The two lower junction points are configured to securely accommodate a removably-coupled handle-coupling strap, and are the locations to which the straps can be secured, preferably with a suitable knot. The two lower juncture points are configured to resist lateral slippage of the straps in order to laterally stabilize the load against which the user is working, and to accommodate knots having excellent holding strength.


A balanced survey is automatically created in real time, that is, while potential survey participants are evaluated. A survey histogram is automatically re-balanced with each new entry accepted as a respondent. An individual fills out a questionnaire providing demographic and socio-economic data. A vector representation of that person, referred to as an entry, is created. A similarity value is calculated indicating the similarity between the vector representation and a histogram vector representing the makeup of the survey. The similarity value is calculated by taking a dot product of the entry vector representation and the histogram vector. The system then determines whether the similarity value is greater than a similarity threshold value. If the similarity value exceeds the threshold value, the entry vector is integrated into the histogram vector, that is, the individual becomes part of the survey group.


A system and method of handling remote check presentment (RCP) of a check may include receiving, from a computing device of a user, RCP data at a computing device, such as a computer server. A determination, by the computing system, of a risk factor associated with the RCP data may be made. In response to determining the risk factor associated with the RCP data, a determination, by the computing system, as to how to make cash available to the user prior to passing the check for clearance through a traditional check clearing process may be performed. The cash may be made available as determined to the user prior to passing the check for clearance through the traditional check clearing process.

User-manipulated exercise equipment of the type utilizing a weight-plate stack comprises a stack of weight plates, of which a user-selected portion moves as a unit along a pair of guide rods in response to an exercise movement by the user. The selected portion of the stack moves with virtually no cross-wise (i.e., lateral) shifting among the plates and virtually no friction between the moving portion of the stack and the guide rods because (1) a keystone bushing below the weight plate stack provides virtually error free alignment with the guide rods by setting the non-selected portion of the stack at a highly accurate home position that resets the moving stack if it has shifted laterally during movement, even if that shift is very slight, and (2) the guide rod holed in the weight plates carry bushings which align with the bushings of the adjacent weight plates to prevent the plates within the moving portion of the stack from shifting laterally with respect to each other and thereby contacting a guide rod. Preferably, the topmost weight plate in the moving portion of the stack carries bushings forming a smaller gap with the guide rods than the bushings of the remaining weight plates so that, at worst, only the topmost plate will contact a guide rod resulting in negligible friction.
