    Abstract: Provided are devices and methods for detecting the presence, absence, and/or characteristics of bacteria. A microfluidic device for characterizing bacteria is provided. The device contains one or more bacteria trapping channels, and one or more pneumatic channels in contact with the bacteria trapping channels, wherein the one or more pneumatic channels are configured to reduce the height of the one or more bacteria trapping channels to thereby trap bacteria in the one or more bacteria trapping channels if said bacteria are present in a liquid biological sample that is introduced into the microfluidic device. Also provided is a method for identifying bacteria that may be used with the microfluidic device.

    Abstract: Tuning fracture hydraulic conductivity can be provided so that high hydraulic conductivity in high temperature zones and low hydraulic conductivity in low temperature zones can be defined in enhanced geothermal systems (EGS). Uniform thermal gradient along flow paths can be provided or defined to help provide such conductivity zones. Experimentation performed to evaluate embodiments showed that embodiments could prevent appearance of dominant flow paths between the wells and maintain high heat extraction rates. Embodiments can greatly increase cumulative heat extraction. Embodiments can also be provided for application solely to the injection wells. Other embodiments can position tuning agents between the wells and still help provide control of the fluid flow in the reservoir and enhance heat extraction.

    Abstract: Methods and systems facilitate measuring flow properties of a material, such as biomass materials, that include different material particles. Sample holding plates securely hold material particles and secure them to sample holders. A normal force actuator applies a normal force between material particles held by the sample holding plates and a sliding force actuator applies a sliding force. Normal and sliding force sensors monitor the transmitted forces, allowing a processor to determine adhesion and friction characteristics between particles held by the first and second sample holding plates.

    Abstract: A sound absorbing panel includes a cavity section having a plurality of resonant cavities and a front panel having a plurality of sets of openings. Each set of openings is configured to provide fluid communication between one of the plurality of resonant cavities and the environment. Each of the plurality of resonant cavities has different dimensions from the remaining plurality of resonant cavities such that each of the resonant cavities is tuned for a different frequency range. Each of the sets of openings can differ from the remaining sets of openings in opening size, length, and distance between openings.

    Abstract: Embodiments relate to a flow loop system for estimating wellbore circulation density. The flow loop system includes an eccentric annulus structure having an inner eccentric pipe and an outer pipe. The inner eccentric pipe can be representative of a drill string in a wellbore. The outer pipe can be representative of the wellbore. The flow loop system includes a pressure sensor configured to measure pressure loss gradients of annular flows between the inner eccentric pipe and the outer pipe. The flow loop system includes a wellbore circulation density processing module configured to estimate the wellbore's bottomhole pressure based on the measured loss gradients of annular flows of fluid and solid particles, rotation of the inner eccentric pipe, and eccentricity of the inner eccentric pipe.
