Abstract: A continuously tunable linear phase filter having a ground connection includes a three-terminal Bessel filter having an input terminal for receiving a signal, an output terminal for delivering a signal, a control terminal for receiving a control voltage, and a varactor. Each of the terminals are in signal communication with each other and the varactor is in signal communication with each of the terminals and ground, the varactor being responsive to the control voltage at the control terminal. The capacitance of the varactor is continuously adjustable in response to a change in the control voltage at the control terminal, thereby enabling continuous tuning of the continuously tunable linear phase filter in response to the control voltage.

Abstract: Aspects of the present disclosure relate to various exemplary embodiments of drawer inserts or organizers. One particular exemplary embodiment includes an apparatus for use within a sliding drawer. The apparatus generally includes a base having at least one storage compartment and at least one tray including at least one storage compartment. At least one link couples the tray to the base such that the tray is pivotably moveable relative to the base between at least a stowed position and a deployed position with the tray remaining generally horizontal relative to the base. The apparatus is configured relative to the sliding drawer and structure supporting the sliding drawer so as to not interfere with the sliding operation of the drawer when the apparatus is positioned within the sliding drawer and the tray is in the stowed position.

Abstract: The present invention is related with the neurobiology and the transgenic animals, more specifically with obtaining a model to study the SCA2 genetic disease. The genome of one mice line has been modified through the introduction of a DNA segment that contains the necessary information for the synthesis of the human ataxin 2. In particular the invention is related with the transgenic mice F066 and the cellular lines able to express the human sca2 gene under the regulation of its self promoter. The F066 transgenic mice reproduce the features of the disease. The homozygous transgenic mouse line for the new gene was obtained through matting. This transgenic line is useful to study the mechanism that produce the disease and also will permit to prove new therapeutics that contributes to minimize the clinical symptoms in the patients.

Abstract: The teaching device of our invention comprises two books --numbered I and II-- each containing a plurality of questions in a given language. Each question is numbered and followed by an answer that serves as a model of the grammatical structure that should be used in answering them correctly. Book I contains questions successively numbered with odd numbers (1-3-5-7-9 . . .), and Book II contains questions successively numbered with even numbers (2-4-6-8-10 . . .). The questions are designed and coordinated so as to simulate a conversation. In use, two students are paired off, with one student using Book I and the other student using Book II. The student using Book I initiates the conversation by reading question #1 aloud to the other student who then answers the question without the help of any printed matter. This forces the student answering the question to develop his own response. Afterwards, it is his turn to read question #2 from Book II aloud.
