A NOTE TO ENGINEERING ALUM
time once again for an update on the JBU engineering
hope that you are all doing well. All the
faculty and staff in the engineering program would
love for you to send us an email and let us know
what you are up to.

MENTION AT P3 AWARD COMPETITION
Several of our students were
awarded an Honorable Mention at the 4th Annual P3
(People, Prosperity, and the Planet) Award
competition in Washington, D.C. The EPA and its
40 partners launched the P3 Award in 2004 to respond
to the challenges of the developed and developing
world in moving toward sustainability. This national
competition enables college students to research,
develop, and design scientific, technical, and policy
solutions to address sustainability challenges. Their
designs are helping to achieve the mutual goals of
economic prosperity while providing a higher quality
of life and protecting the planet.

Here are some details on the JBU project.
The proposed research project question is: “How can
a slow-sand water purification system be improved to
meet the needs of a small community?” A major issue
that persists in underdeveloped areas is both water
quality and quantity. There have been point-of-use
water purification systems developed that can
provide for particulate removal, bacteria
destruction, or both. However, large-scale community
systems have remained too expensive for
underdeveloped communities. This project has three
goals: 1) to perform research and development tasks
that would increase the throughput of the slow-sand
technology; 2) to design the research outcome into a
total community system design that would be
applicable to a wide variety of communities; 3)
to develop an educational strategy that would provide
for indigenous community integration, maintenance,
While slow sand filters exist, the research will
examine a greenhouse test bed for process improvements
that would yield a filtration process that will have
a sustainable community level flow rate, design a
preventative maintenance process that will create a
micro-enterprise while sustaining water quality, and
evaluate structural improvements for both improved
flow rates and ease of maintenance. This task will
be accomplished through a series of key tasks: 1)
construct a small scale test bed; 2) complete
experimental characterization of the Schmutzdecke
layer for water flow rates and filtration; 3)
incorporate structural modifications for increased
flow; 4) develop optimal maintenance procedures that
are culturally appropriate; and 5) develop
educational and micro-enterprise plans for
sustainable integration into a host community. This
project has the support and commitments from
Students In Free Enterprise and The Institute for
Biblical Community Development as partner NGO’s.
you know, the engineering program at JBU is
accredited by the Engineering Accreditation
Commission of ABET (http://www.abet.org).
We have our reaccreditation visit coming up and have
spent the last several months preparing the
self-study. The visit should occur sometime in
October or November, and the faculty are looking
forward to showing off our program. Your
prayers for a good visit would be appreciated.
mentioned in last year's newsletter that the Cathedral, Engineering
(formerly the library), and Art (formerly Science)
Buildings were undergoing some renovation. The work
is almost complete, and the buildings look great
with their new limestone exteriors. We are
also very appreciative of the new windows and HVAC
system installed in the Engineering Building as part
of this renovation.

Department was able to purchase a Dimension SST 768
3D printer last summer. Students can now
design a part in SolidWorks and then build the part
out of ABS plastic. We are very excited to
have this rapid prototyping capability.
Dimension printer builds functional 3D models from
the bottom up, one layer at a time with tough,
durable acrylonitrile butadiene styrene (ABS)
plastic. STL files are imported into the
Catalyst® EX Software, which automatically slices and
orients the parts and creates any necessary support
structures. The software automatically plots a
precise deposition path for the printer to follow.
ABS plastic (in filament form within auto-loading
cartridges) is fed into an extrusion head, heated to
a semi-liquid state and deposited in layers as fine
as 0.01-inch (0.245 mm) thick. After completion of
the build, support structures are dissolved.

2008 SENIOR DESIGN PROJECTS
year there were 12 senior design projects sponsored
by six different organizations.
Engineering Advisory Board continued to sponsor a
design competition in conjunction with the senior
projects with two categories: Best Technical Design
and Greatest Social/Global Impact. The winners in
each category received $100 and had their
names put on a plaque in the Engineering Building.
The runner-up received $50. The results

Thanks to the generosity of alumni and friends of
JBU, $69,800 will be awarded to engineering students
in the coming year from funded and endowed
scholarships that are designated for engineering
students. Of course, engineering students receive
much more in financial aid than this $69,800 since
there are also other scholarship awards from the JBU
Scholarship Fund and other need and merit based
scholarships available to all JBU students.

has provided another wonderful opportunity that John
Brown University president, Dr. Charles Pollard,
announced last year. The university is in the midst
of a new challenge campaign that will add $20
million to the JBU endowment fund for student
scholarships and essential programs.
The $20 Million Campaign comes on the heels of the
highly successful $10 Million Challenge for endowed
scholarships that was completed in January 2007. A
donor, who wishes to remain anonymous, has pledged
up to $10 million in matching funds to initiate a
new $20 Million Endowment Challenge for JBU. Funds
raised will be matched up to $10 million for all
current and deferred gifts designated to new or
existing endowed scholarships and for endowing
important programs across campus. JBU has five years
to raise their $10 million portion in order to
receive the full amount of matching funds. Together,
JBU’s raised funds and the matching funds will add
$20 million to JBU’s endowment. This is another
opportunity to support the University and the
