The Maryland 4-H Engineering team has returned from a successful trip to Lafayette, Indiana, for the 53^rd National 4-H Engineering, Science and Leadership Event, September 28-30, 2003. The seven-member team participated in individual events and then as a team in the 4-H Engineering Bowl. They also attended educational workshops at Purdue University and educational field trips in Lafayette and Indianapolis. The event had 59 4-H youth from 12 states.

First place MD winners included Jason Ridinger (Carroll County) in Automotive Safety, and Joshua Stewart (Carroll County) in Lawn Tractor.

Samuel Evans (Montgomery County) placed second in Small Engines. Kyle Barber (Carroll County placed third in Automotive Safety, and Christina Engblom (Anne Arundel County) placed fourth in Bicycle Safety. The first place team in Automotive Safety was Jason Ridinger and Kyle Barber.

Fifth place winners included Gregory Stewart (Harford County) in Agricultural Tractor and Patrick Dibello (Calvert County) in Computer.

The team competed to a close finish in the second round of the 4-H Engineering Bowl, losing by one answer. Each event included a written test and either a presentation or parts identification test and skillful operation of a vehicle. Safety was emphasized in all phases of the event.

Dr. David Ross, Extension Agricultural Engineer, Biological Resources Engineering Department, University of Maryland, College Park, MD, was the Group Coordinator and Chair of the National Bicycle Safety Event. Dr. Lee P. Grant, Emeritus Associate Professor from the department, was chaperone and Chair of the Lawn Tractor Event. Mr. Barry Brook, Faculty Extension Assistant in the department, served as chaperone and Judge in the Bicycle Safety Event.

Extension Agricultural Engineers and 4-H professionals from participating states conducted the event. Deere and Company and Lincoln Electric are national sponsors of this program.

Mr. Barry Brook has joined the Biological Resources Engineering Department as Faculty Extension Assistant to promote bicycle and automobile safety to 4-H youth. Welcome to the Department.

Everyone always seems to be interested in the current design projects for ENBE 454, Biological Process Engineering. Are they easier or harder than the ones you had to face when you were taking the course? To satisfy your curiosity, here are four of the design projects assigned during 2002 and 2003.

1. Fluid Flow Design Problem - Spring 2002

Events of the past year have convinced the University administration that protection against bioterrorism must be assured. For this reason, we need the ventilation systems in the various laboratories of the Biological Resources Engineering Department to be modified to remove anthrax endospores should they be introduced into either the air surrounding the building or the air inside the labs. You are to provide means to do this while still assuring that the labs are adequately ventilated. To assist in this project, you may need to visit the facility control room where the ventilation systems are located, consult the architectural drawings, or investigate relevant air handling recommendations. (Do rooms 504, 513, 530, 532, 534).

2. Mass Transfer Design Problem - Spring 2002

Entremed is producing two vascularity-inhibiting proteins called Angiostatin and Endostatin for tumor inhibition. Both of these are produced by genetically modified yeast cells in bioreactor tanks. These tanks are maintained at 22-24^oC, pH is maintained at 3-6, and methyl alcohol is used as a trigger to produce the proteins. Thirty to fifty percent of the mass of the medium is composed as cells; the other 50-70% is liquid containing the desired proteins. Sucrose octyl sulfate, when bound to the protein makes the protein more soluble. Soluble proteins are each about 20K Daltons in size. Cells are 3µm.

The tank concentration of protein is 0.2-1 gr/L. The required concentration is 8 gr/L. Desired production rate of the concentrated protein is 100L/(5-6 hr). Design a membrane filtration system for this application.

3. Heat Transfer Design Problem - Spring 2003

Organogenesis produces thousands of synthetic skin grafts per month. These are made in Petri dishes filled with a liquid nutrient that stimulates skin growth by mimicking its natural environment. Dermal cells from infant foreskin tissue are first spread over a collagen matrix which is set in a shallow, round dish well-bathed in nutrient medium. The lower layer of skin incubates at 37^oC for six days. The nutrient bath is changed every day. On the sixth day, epidermal cells are spread over the lower layer of skin and the Petri dishes are again incubated at 37^oC. On the tenth day, the skin is lifted out of the culture bath so the top is exposed to air. For the next 10 days, the outer tough layer of skin, known as the stratum corneum, is developed. This entire process is performed by hand.

The firm wants to introduce industrial-scale automation to increase its capacity from 50,000 skin grafts per year to 500,000 skin grafts per year. What is needed is a controlled environment in which the cell inoculation, nutrient exchange, and temperature control are performed as automatically as possible. Propose a system to:

1. Automatically inoculate the Petri dishes or their equivalent (depending on what you propose).
2. Exchange nutrients. Include fluid handling specifications.
3. Maintain temperature at 30^oC for the first 10 days and 34^oC for the next 10 days. Include the required amount of heat necessary and the means by which heat will be introduced to the samples.

The system must also be sterile and accessible to human monitors.

4. Mass Transfer Design Project - Spring 2003

Finding useful means to dispose of waste water biosolids can be a challenge. One proposed solution is to inject them into the ground, grow hay, and donate the hay to wildlife parks, animal rescue organizations, and therapeutic riding centers.

To avoid costly transportation and handling of large volumes of water, the waste water - biosolids are to be concentrated using a membrane filtration system.

For a waste treatment plant with 40 million liters of discharge per day,

1. Determine the concentration ratio to be specified.
2. Specify a membrane filtration system:

   type
   area
   pressure

3. Design the pumping, piping, and storage associated with the filtration system.
4. Suggest uses for the water removed.
