We report our techniques on conducting a closed-circuit femoral-femoral bypass during descending aortic surgery by which collected blood can be easily returned into the right atrium. The main circuit was composed of a centrifugal pump, an artificial membrane lung, and a filter. A reservoir with a roller pump was connected to the main circuit via a filter. Extracorporeal circulation was establis...

in order to solve the problem of fuel pollution, the diesel fuel for power generation of marine was abandoned and shore power supply have been proposed at the historic moment. the shore power supply which needs transferring 380v/50hz to 450v/60hz is used on shipping who need this kind of power, so effectively curbs the emissions of pollution gas into the air, and achieves the purpose of improvi...

Like many behaviors, Caenorhabditis elegans egg laying alternates between inactive and active states. To understand how the underlying neural circuit turns the behavior on and off, we optically recorded circuit activity in behaving animals while manipulating circuit function using mutations, optogenetics, and drugs. In the active state, the circuit shows rhythmic activity phased with the body b...

PurposeDirect procurement of thoracic organs as compared to using abdominal normothermic regional perfusion (aNRP) is the preferred method for organ in donors after circulatory death (DCD). The use aNRP improves outcomes from liver transplantation. We have developed a technique isolation during that allows successful co-procurement and organs.MethodsIn order achieve both brain volume loss must ...

Battery safety tests are defined by several international standards in different ways and with heterogenous termination failure criteria. In this work, lithium-ion cells were examined regarding their behavior the event of overcharging also an external short circuit varied parameters specified standards. The voltage, current, temperature curves evaluated. addition, changes analyzed using electro...

This paper reports on the fabrication and characterization of high-quality factor (Q) single crystal silicon (SCS) in-plane capacitive beam resonators with sub-100 nm to submicron transduction gaps using the HARPSS process. The resonating element is made of single crystal silicon while the drive and sense electrodes are made of trench-refilled polysilicon, yielding an allsilicon capacitive micr...

This circuit is a fourth-order low-pass filter with values for kHz. The values of Rv R2, C and C2, and R3, R4, C3 and C'4 can be scaled for operation at other. Draw the schematic diagram for the circuit to be analyzed. 3. A typical low-pass filter circuit, for example, might have a frequency response that looks like this:. Related Questions. Can I use an RC low pass filter to reduce noise on th...

A Bäcklund transformation(BT) and a recurrence formula are derived by the homogeneous balance(HB) method. A initial problem of Burgers equations is reduced to a initial problem of heat equation by the BT, the initial problem of heat equation is resolved by the Fourier transformation method, substituting various solutions of the initial problem of the heat equation will yield solutions of the in...
