Performance of Small-Fruited Pumpkin Cultivars in Maine David T. Handley*, Mark G. Hutton and Gregory J. Koller, University of Maine Cooperative Extension and Maine Agricultural and Forestry Experiment Station, Highmoor Farm P.O. Box 179, Monmouth, ME 04259 dhandley@umext.maine.edu

Performance of Small-Fruited Pumpkin Cultivars in Maine David T. Handley*, Mark G. Hutton and Gregory J. Koller, University of Maine Cooperative Extension and Maine Agricultural and Forestry Experiment Station, Highmoor Farm P.O. Box 179, Monmouth, ME 04259 dhandley@umext.maine.edu

Materials and Methods The trial was established at Highmoor Farm, part of the Maine Agricultural and Forestry Experiment Station, in Monmouth, Maine. The site has a silt loam soil, which was amended with 10-10-10 fertilizer at a rate of 500 lb/acre and incorporated prior to planting and application of black plastic mulch. Three replications of seven pumpkin varieties were direct-seeded in a randomized complete block design on 18 June. Plots were 18 feet long with three feet between plants (6 plants/plot) and six feet between rows. The treatments included: 1. Small Sugar; 2. Baby Pam; 3. Mystic Plus; 4. Field Trip; 5. Chucky; 6. Fall Splendor; 7. Winter Luxury. Fruit were harvested on 18 September. Data was subjected to Analysis of Variance and mean separation using the test for Least Significant Difference. Results & Discussion The variety ‘Chucky’ produced significantly more fruit than any other variety in the trial, with the exception of ‘Small Sugar’ (Table 1). There were no significant differences in fruit number per plot among the other varieties, although the range was considerable. ‘Fall Splendor’ and ‘Winter Luxury’ produced the largest fruit in the trial by weight, followed by ‘Mystic Plus’ and ‘Field Trip’. ‘Chucky’ and ‘Baby Pam’ produced the smallest fruit. Fruit height and diameter data indicate that ‘Field Trip’ was the widest variety, with the most flattened-shape, typically associated with pie-type pumpkins. ‘Baby Pam’ and ‘Mystic Plus’ also had more flat...

Redesign of Bennett Hall HVAC System _____________________________________________________________________________________________________________________________ Greg Andreasen, Michael Chicoine, Florent Hoxha, Jason Jacobe Advisor: Michael “Mick” Peterson, Ph.D. and Justin Poland, Ph.D. Background Heat Ventilation and Air Conditioning (HVAC) systems are systems that treat and circulate the air of a building to make it comfortable for people to work in. The HVAC system consists of a series of fans, pumps, and coils that heat or cool the air as needed and transport the air to desired destinations throughout the building. An HVAC system also regulates the humidity of the air in the building by cooling the air to very low temperatures and heating it back up. The figure below is a schematic of the HVAC system in Bennett hall. The Central Air Handler takes the air in from outside and it either cools it by running it through cooling coils, or it heats it passing through heating coils (depending on the season). The air is then brought to the individual room unit coolers which mix re-circulated room air with the ventilation air and provide additional cooling, in summer, as needed. This way each room in the building becomes a comfortable working area.   Figure 1. Problem When the Bennett Hall HVAC system was installed, the system was designed to control only the temperature of the building. The humidity level was not factored into the system’s design. The h...

Tidal Turbine Hub-Blade Interface Matthew Fowler Mark Pemberton Andrew Litchfield Dan Kittridge The goal of the Tidal Turbine Hub-Blade Interface project is to take knowledge gained from the history of wind and tidal turbine design and design a standard hub-blade connection. By using computer models to analyze several different commonly used hub-blade connections, the design least susceptible to failure under common tidal loads can be identified. We are conducting material tests on the composites used in these types of turbine blades in order to ensure the accurate modeling of their behavior. Using SolidWorks to create solid models and Abaqus to conduct finite element analysis, we are working towards the determination of a superior hub-blade interface.

Engineering & Science Research Building (ESRB) Economic Analysis Refrigeration Cycle Turbocor TT400 Compressor ESRB constructed in 2004 $16 million to build Laboratory space for engineering research Laboratories require 54,000 CFM of ventilation air No recirculation, 100% outdoor make-up air Plans for water-glycol heat recovery system put on hold Currently no heat recovery system installed Will outperform a water-glycol system Average savings of $5.50 per hour Annual savings of $24,000 Five year investment return Variable speed two stage centrifugal compressor Levitating magnetic bearings do not need lubrication Extremely quiet operation Economizer port to increase efficiency Capable of very high coefficient of performance (COP) Takes advantage of latent heat of vaporization to transport heat Evaporator coil reclaims heat from warm exhaust air Condenser coil rejects heat to cold make-up air The university’s steam plant is responsible for heating over 80 buildings on campus. The steam plant burns 64,000 barrels of No. 6 fuel oil per year resulting in 320 million lbs of steam. At a cost of approximately $35 per barrel this equates to $2.24 million per year spent on heating. The installation of heat recovery systems on campus could greatly decrease the university’s heating bill. As a result the money saved could be used to fund other projects. As of right now it costs roughly $96,000 a year to heat the ESRB. Without a heat recovery system a...

The stock cowling cannot be used on the modified snowmobile due to the under hood clearance issues brought on by the addition of emission control hardware. Two replacement hoods have been built previously and yielded mixed results. Neither of the hoods looked particularly appealing, and both had fitment and performance issues. This years hood was made using a three stage process. The first stage was to create a plug in the desired shape of the hood. This was made from a rough shape of plywood and foam, which was then covered with a layer of Bondo to smooth and create the final shape. The next stage of the build was to create a female mold of the hood out of fiberglass. We took the male plug we had made, applied paint and a release agent to it and carefully laid many small layers of fiberglass over the plug. This gave the mold the shape of the plug while enabling the fiberglass to take the shape of the plug with minimal deviations. Once the hand lay-up of the mold was completed, a practice hood was made. We used the SCRIMP resin infusion process for this. This is a vacuum process that pulls the resin over the surface of the material, eventually fully infusing the fabric evenly. It gives a closer to optimal fiber-volume ratio while reducing void spaces. Once we had established a working process, we made the final hood out of carbon fiber and had it gel-coated and painted by a local bike shop. Motivation Goals It can be seen in the pictures that this years cowling...

Amanda D. Kimball Andrew Bennett Brennan Johnson Timothy Hardy Problem The Engineering & Science Research Building houses laboratories which require high ventilation air rates. 54,000 cubic feet per minute of outside air are needed twenty-four hours per day seven days a week to meet OSHA regulations. There are currently no systems installed to recover wasted energy that is released to the atmosphere after passing through the building’s air ducts. Solution The Advanced Heat Recovery Project seeks to design and install an air recovery system to decrease the amount of energy required to maintain OSHA requirements at the Engineering & Science Research Building. The heat recovery system will take advantage of a direct expansion heat pump which has the capability to recover more energy with greater efficiency than a traditional water-glycol system. TurboCor Compressor Engineering & Science Research Building Mechanical Engineering 2007-2008 Refrigerant Flow Diagram in Heating and Cooling SolidWorks Model of Heat Recovery System Return on Investment: $99,000 per year for $195,000 capital cost. Environmental Benefits: Reduced carbon dioxide and sulfur dioxide emissions. Helps the University meet new emissions standards. Demonstrates best practice in building design.

Optimization of the Oscillating Hydrofoil Propulsion System Sarah Blake, Scott Eaton, Mary Girard and Hassan Mazi Advisor: Michael “Mick” Peterson, Ph.D. Background The Human Powered Submarine Contest is an annually held student competition. Since the fall of 2001, the Mechanical Engineering Department has been developing its own human powered submarine which they hope to enter in the competition for the first time in summer 2005. Previous senior design groups dealt with design and fabrication of the hull, control system, and buoyancy control. The Hobie MirageDrive, a set of two oscillating hydrofoils, was chosen as the propulsion method for the submarine. This drive was designed to be operated using a stepping motion. Problem The first design problem with the submarine was to attach two sets of oscillating hydrofoils together. Each MirageDrive has two input links, which move in opposite directions. The original connecting method, which formed a four-bar linkage, prevented smooth motion through the hydrofoil cycle. The second design problem was mounting the hydrofoil sets to the submarine hull while constraining their motion in three directions. The submarine hull has a foam core which is weak in compression, so a large surface area is needed for mounting. Objective Our task was to optimize the oscillating hydrofoil propulsion system for the human-powered submarine. Specific results of this project are: Design of connecting links between two hydrofoil sets F...
