EXTENSION AND OUTREACH ACTIVITES (partial list)
In cooperation
with Prof. George Duncan, we have obtained support from the Burley Tobacco
Council to improve humidity control in greenhouses used to germinate and grow
tobacco transplants. These plants are raised in float trays, and moisture
control requires proper adjustment of ventilation and heating systems to
balance energy costs, plant hardiness, disease control, and ease of operation.
Example
automated systems for mechanical and curtain-sided houses were developed and
installed in four cooperators facilities (Lincoln, Davies, Shelby (2), and
Montgomery counties), and monitored for two years to obtain data on
performance, suitability of use, and assess humidity control.
Outcomes of the
project to date include: an extension fact sheet, a draft video on greenhouse
ventilation basics, web-based presentations on greenhouse control for Extension
Agent training, development of quizzes for Cooperative Extension County Agent
Training, and presentation of findings for both mechanically ventilated and
curtain-sided automation.
We are currently
working with an instructor at West Jessamine County High School who is using a
leaf wetness sensor circuit that we developed as a project for students, with
testing in greenhouses scheduled for Spring 2001.
Recent
activities have included
·
Development of algorithms, wiring, installation and
testing of TIV control in Kentucky and New York dairy facilities.
·
Work with Kentucky broiler companies’ concerns for
young, partially-feathered birds in tunnel ventilation experiencing wind chill.
Provided estimate of effective temperature and guidelines for maximum tunnel
velocity at different ages of birds.
·
Trouble-shoot and evaluate environment controls in
pullet houses with excessive heating bills, condensation and poor indoor air
mixing. Provide guidelines and education of fundamentals.
·
Evaluate and provide guidelines for daily management of
broiler facilities at high elevations in a dry climate, with poor inlet control
and significant dust. Developed a method for manual inlet adjustment for
workers, based on simple count of number of fans operating (Maputo, South
Africa)
·
Cooperate with colleagues (Dr. Tobin, Harkin) in Gluck
Equine Center to develop two systems for Kentucky horse industry. The first is
a motion system to assess the efficacy of different drug dose-response via
animal activity, rather than blood samples. A second project involves early
lameness detection (navicular disease) utilizing a force plate to obtain weight
distribution. This latter system was constructed and tested for an M.S. project
(C. Holtz) and is now an BAE senior design project.
