摘要:
Performance based delivery of content to an audience member. A network of audience member information collection domains provide information about audience members. A profiled audience member may belong to a network segment. Delivery of an advertisement to the profiled audience member is accommodated based upon membership in the network segment and performance criteria. The performance criteria may be configured to benefit a publisher, such as by maximizing revenue. Allocating revenue based upon the collection of data used to target audience members is also provided.

The expense of provide pelletized metallic lithium for use in a heat exchanger for a thermal power source is eliminated by a construction including a closeable chamber (10, 12, 20, 22) with an ignition device (28) within the chamber (10, 12, 20, 22), and a reactant inlet (29) to the chamber (10, 12, 20, 22) by disposing a body of fuel (24) in the chamber (10, 12, 20, 22) which is made up of alternating layer of metallic lithium sheet (42, 44) and solid perhalogenated polymer sheet (40, 46).

A method of treating an amyloid disease by administration of cactus mucilage extract from Opuntia ficus-indicia is presented. Both gelling and non-gelling cactus mucilage extracts were found to induce changes in the secondary structures of the amyloid beta peptides thus interfering with formation of Aβ fibrils and aggregation of Aβ fibrils into plaques.
摘要:
Alzheimer' s disease (AD) is the common neurodegenerative disorder characterized by the formation of extraneuronal accumulation of amyloid fibrils and intracellular neurofibrillary tangles of Amyloid β-Protein (Aβ) into plaques. Cactus mucilage extracted from Opuntia ficus-indica was analyzed in disturbing the aggregation pathway of Amyloid β-Protein (Aβ) fibrils and α-synuclein. Mucilage is a pectin polysaccharide with a backbone of α-D-galacturonic acid and β-L-rhamnose and a branch of arabinose or xylose. Two different fractions of mucilage can be extracted: pectin gelling extract which forms gels in the presence of Ca2+ ions (GE) and non-gelling extract (NE). The effectiveness of mucilage in disturbing the formation of Aβ fibrils was evaluated. Aβ monomeric species have been incubated along with different concentration of the mucilage extract in vitro. The aggregation kinetics of the Aβ proteins were monitored by Fourier transform infrared (FTIR) spectroscopy. Transmission electron microscopy (TEM) was used to monitor the aggregation process and fibril morphology. Our results indicate that introducing mucilage induces changes in the secondary structures of the Aβ peptides and results in amyloid detribalized structures. Our experimental results support the effectiveness of cactus mucilage in interfering with protein accumulation pathway and targeting the Aβ plaques.
摘要:
Described herein is a method and apparatus for the detection of signals in an area of interest. Three sensor channels are provided for sensing radiated emissions in an area of interest, each channel having a sensor and a processor, the three channels sensing radiated emissions in the very low frequency band, the high/very high frequency band, and the ultra high frequency band respectively. The first and third sensor channels provide input signals to the processor in the second sensor channel so that accumulated signal data can be processed to produce an input signal for a comparator. The comparator compares the input signal with data stored in a database to indicate presence of equipment having known modes of operation.
摘要:
An apparatus and method for regenerating spent ion exchange resin is described. In one method, a fresh regenerant solution comprising sodium ions and chloride ions is prepared, and passed across spent cation exchange resin to regenerate the spent resin. To recover the spent regenerant solution, a regenerant treatment composition is added to the spent solution to form precipitate flocs, which are then separated out of the regenerant solution. The concentration of at least one of the sodium or chloride ions in the regenerant solution can also be adjusted to form fresh regenerant solution which can be reused.
