摘要:
Provided herein are methods and compositions for increasing the production of one or more cellulases from a fungal host cell. The disclosure is based, on the surprising discovery that mis-expression of the transcriptional regulator clr-2 in a filamentous fungal cell was able to induce expression of cellulase genes under non-inducing or starvation conditions, resulting in increased secretion of cellulases from the cell. Advantageously, mis-expression of the transcription factor clr-2 in a filamentous fungal cell cultured in the absence of cellulose or cellobiose results in increased secretion of cellulases. The disclosure relates inter alia to a method of degrading cellulose-containing material, to a method of increasing the production of one or more cellulases from a fungal cell and to a method of reducing the viscosity of a pretreated biomass material, by contacting pretreated biomass material with a fungal host cell containing at least one recombinant nucleic acid encoding clr-2 or a related transcription factor.

摘要:
A system of teaching piano playing and music theory having piano cards. Piano cards are a flash card system with piano note information on each card. These piano cards are placed above piano keys of a piano or other keyboard designating keys to be played in a specific scale. Black and white triangles on these piano cards designate ebony and ivory keys to be played and can only be placed on a keyboard correctly if aligning white and black triangles with ebony and ivory keys. Triangles designate fingers to be used on fingering cards by way of numbers designating fingers. On music theory cards numbers inside triangles designate scale degrees. On chord cards numbers designate degrees to be played. This music teaching system further comprises a music wheel that has been color coded designating the key a scale is in.

A fertilizer applicator is provided for use with a sprinkler line system. The applicator comprises a fertilizer container with integrally formed internal inlet and outlet tubes. Water is fed through an inlet-outlet tube into the bottom of the fertilizer container, where it dissolves or dilutes some of the solid or liquid fertilizer and forms a leached, concentrated solution. This concentrate continuously rises through the fertilizer and into the outlet tube where it drains downwardly. The concentrate is then diluted with water coming through the inlet-outlet tube including a venturi, the size of which controls the flow rate of the concentrate. The diluted concentrate is then passed into the sprinkler system for application to vegetation. The applicator has a single piece, simplified design, without moving parts, and does not leak fertilizer into the drain. Also, the bore arrangement of the applicator enables the device to be drained and then filled with fertilizer, without fertilizer leakage, followed by running water through the fertilizer at any selected time, and this renders the operation more automatic.

摘要:
A system for conducting commerce across a distributed network includes a remote consumer computer. A merchant server communicates with the remote consumer computer across an open network to enable purchasing of a product from the remote consumer computer. A financial clearing house server is located within a secured closed network and communicates with the remote consumer computer and the merchant server across the secured closed network. The merchant server creates a merchant ID, receipt ID and transaction total corresponding to a consumer transaction and sends the merchant ID, receipt ID, and transaction ID to the financial clearing house server and the remote consumer computer. The financial clearing house server arranges payment of the transaction in response to a matching merchant ID, receipt ID, and transaction total from the remote consumer computer.
