摘要:
A redox fuel cell comprising an anode and a cathode separated by an ion selective polymer electrolyte membrane; means for supplying a fuel to the anode region of the cell; means for supplying an oxidant to the cathode region of the cell; means for providing an electrical circuit between the anode and the cathode; a non-volatile catholyte solution flowing fluid communication with the cathode, the catholyte solution comprising a polyoxometallate redox couple being at least partially reduced at the cathode in operation of the cell, and at least partially re-generated by reaction with the oxidant after such reduction at the cathode, wherein the polyoxometallate is represented by the formula: Xa[ZbMcOd] Wherein X is selected from hydrogen, alkali metals, alkaline earth metals, ammonium and combinations of two or more thereof; Z is selected from B, P, S, As, Si, Ge, Ni, Rh, Sn, Al, Cu, I, Br, F, Fe, Co, Cr, Zn, H2, Te, Mn and Se and combinations of two or more thereof; M comprises W and optionally one or more of Mo, V, Nb, Ta, Mn, Fe, Co, Cr, Ni, Zn Rh, Ru, Tl, Al, Ga, In and other metals selected from the 1st, 2nd and 3rd transition metal series and the lanthanide series; a is a number of X necessary to charge balance the [ZbMcOd]a− anion; b is from 0 to 5; c is from 5 to 20; and d is from 1 to 180.
摘要:
DNA sequences encoding human androgen receptor protein and polypeptides and proteins having substantially the same biological activity as human androgen receptor protein and the amino acid sequences of human androgen receptor protein and polypeptides and proteins having substantially the same biological activity as human androgen receptor protein are disclosed. Methods for the production and use of such compositions are also disclosed.

A method of processing of solar cells includes determining that a back-contact solar cell is defective. The back-contact solar cell includes a first plurality of interconnect pads at a first edge thereof, and a second plurality of interconnect pads at a second, opposed thereof, the first and second pluralities of interconnect pads having opposite operational charges. The back-contact solar cell is then diced to define at least first and second back-contact solar cell sections. The first back-contact solar cell section has at least two interconnect pads, of the plurality of interconnect pads, at respective opposed edges thereof.

A multimedia conferencing system has a plurality of remote user terminals, each of which may be different from any other, and each of which may communicate to a central processing hub using different communications protocols. The central processing hub receives, processes, and sends video and audio data from and to the plurality of remote users, and comprises a media bus for handling video and audio data signals, a packet bus for handling data and control signals, a shelf controller card which issues control messages in keeping with incoming management signals, a bus controller card which provides clock and bus arbitration signals, at least one media processor card for processing video and audio signals, and video encoding means for receiving video data from the one or more media processor cards and delivering video data signals to the packet bus. Video and audio data signals may be received by or delivered from any of the at least one media processor card and the at least one physical interface card. A management node communicates through the shelf controller card to permit management signals to be delivered, which may come from a session manager so as to control the nature of the output video and audio data signals which are sent to the remote user terminals. A video link and a video router permit summing of video data signals, and the resultant summed video data signal is passed to a further video data link via the video router so that the video data signal which is returned to the remote terminals is derived from a cascade of video links.
摘要:
The present invention relates to a skin care kit useful skin conditioning. The kit, which includes a skin care composition contained within a dispenser, is particularly useful for providing good moisturization and aesthetics to both cream and lotion users. More particularly, this invention relates to a skin care kit useful for regulating skin condition (especially human skin, more especially human facial skin), including lubricating the skin, increasing the smoothness and suppleness of the skin, preventing or relieving dryness of the skin, hydrating the skin, and/or protecting the skin regulating visible and/or tactile discontinuities in skin, e.g., visible and/or tactile discontinuities in skin texture, more especially discontinuities associated with skin aging.
摘要:
A computer system and computer implemented method to develop a relationship according to a multi-step process. The computer system may define a workflow having multiple stages, each stage having one or more game sessions to develop the relationship between participants. The games in successive stages of the workflow may be designed to encourage increased communication between the participants. A workflow may comprise at least three stages including a connect stage, a play stage, and a meet stage. An initial communication may include a written or asynchronous communication. Increased communication may include a voice, video, or real-time communication.
