IMPACT OF PHYSICOCHEMICAL CHARACTERISTICS AND DISTILLATION PARAMETERS ON THE BIOMETHANE POTENTIAL OF BOURBON STILLAGE

Bourbon, or whiskey, production in Kentucky has been estimated to double within the next five years and an increase in the main by-product from bourbon distillation, stillage. Stillage is composed mostly of water along with the fermented grains after distillation. Stillage is expensive to dispose of and difficult to store due to the high biodegradability, posing a risk to the environment given the low pH and high chemical oxygen demand (COD). Anaerobic digestion has been identified as a potential solution for stillage valorization, but little research has been performed. Stillage from different mash bills has varying physicochemical properties, total solids (TS), volatile solids (VS), pH, and minerals and macronutrients. Distilleries employ varying distillation parameters and coupled with the heterogeneous makeup of the stillage from mash bills, is thought to have an impact on the biomethane potential of stillage. With a minimum methane production of 291.17±3.45 NmL/g VS and a maximum methane production of 419.19 ± 2.61 NmL/g VS out of 10 stillage samples from four distilleries with a food to microbe ratio of 1 g VS/ g VS and an organic loading rate (OLR) of 10 g VS/L, mash bill and distillation parameters were determined to impact stillage biomethane potential

Electronic Switching Spherical Array (ESSA) antenna systems

ESSA (Electronic Switching Spherical Array) is an antenna system conceived, developed and qualified for linking satellite data transmissions with NASA's tracking and data relay satellites (TDRSS) and tracking and data acquisition satellites (TDAS). ESSA functions in the S band frequency region, cover 2 pi or more steradians with directional gain and operates in multiple selectable modes. ESSA operates in concert with the NASA's TDRS standard transponder in the retrodirective mode or independently in directional beam, program track and special modes. Organizations and projects to the ESSA applications for NASA's space use are introduced. Coverage gain, weight power and implementation and other performance information for satisfying a wide range of data rate requirements are included

Performance interface document for users of Tracking and Data Relay Satellite System (TDRSS) electromechanically steered antenna systems (EMSAS)

Satellites that use the NASA Tracking and Data Relay Satellite System (TDRSS) require antennas that are crucial for performing and achieving reliable TDRSS link performance at the desired data rate. Technical guidelines are presented to assist the prospective TDRSS medium-and high-data rate user in selecting and procuring a viable, steerable high-gain antenna system. Topics addressed include the antenna gain/transmitter power/data rate relationship; Earth power flux-density limitations; electromechanical requirements dictated by the small beam widths, desired angular coverage, and minimal torque disturbance to the spacecraft; weight and moment considerations; mechanical, electrical and thermal interfaces; design lifetime failure modes; and handling and storage. Proven designs are cited and space-qualified assemblies and components are identified

Annual Assessment Of Customer Needs And Satisfaction

The Kentucky Transportation Cabinet, both through its own quality initiative and a statewide Empower Kentucky campaign, has a commitment to achieve new levels of quality in the development, construction and maintenance of highways. In order to gage progress, there is a need to establish a baseline of customer satisfaction with the current highway system, and determine needs as perceived by the users of the highway system. As a result, the University of Kentucky Transportation Center, Technology Exchange Unit, was contracted to conduct a customer needs and satisfaction survey. The objectives of this study are to: A. Ascertain Kentucky highway users\u27 opinions on highway program priorities and satisfaction. B. Compare and contrast these opinions with.the data obtained in the NQI Survey. C. Issue a report that can be used to help guide highway investments and strategic planning
