Abstract:
The Department of Neurosurgery at the Medical College of Virginia/Virginia Commonwealth University (VCU) celebrates its 100th anniversary in 2019. It was founded by C. C. Coleman, who directed the US Army School of Brain Surgery during World War I and was one of the original members of the Society of Neurological Surgeons. Coleman began a residency program that was among the first four such programs in the United States and that produced such prominent graduates as Frank Mayfield, Gayle Crutchfield, and John Meredith. Neurosurgery at VCU later became a division under the medical school’s surgery department. Division chairs included William Collins and Donald Becker. It was during the Becker years that VCU became a leading National Institutes of Health–funded neurotrauma research center. Harold Young oversaw the transition from division to department and expanded the practice base of the program. In 2015, Alex Valadka assumed leadership and established international collaborations for research and education. In its first 100 years, VCU Neurosurgery has distinguished itself as an innovator in clinical research and an incubator of compassionate and service-oriented physicians.

Abstract:
Since fall 2015, the University of Virginia’s (UVA) Engineering Student Council (ESC) has partnered with the nonprofit Virginia Science Olympiad (VASO) organization to host a Science Olympiad (SciOly) state tournament in Charlottesville, Virginia, each spring. This annual tournament brings over 2,000 middle and high school students, teachers, and parents to the UVA campus, and teams of 15–17 people from roughly 90 schools across Virginia participate in 46 different events (23 middle school, Division B; 23 high school, Division C) relating to the science, technology, engineering, and mathematics (STEM) fields throughout the day-long competition. The national SciOly organization sets the events and rules to comply with national education standards, and the VASO board coordinates the teams and tournaments within the state. By collaborating with VASO, UVA ESC was able to plan a large-scale SciOly tournament at UVA in approximately 10 mo with the support of the UVA School of Engineering and Applied Science. Since this event was planned and executed solely by undergraduates in cooperation with the nonprofit organization, there were institutional hurdles that were overcome through the months of planning. The Virginia SciOly state tournament has continued to be held at UVA with the support and cooperation of the UVA ESC and VASO, and bringing this tournament to UVA has allowed for increased excitement for participating K–12 students and a mitigated burden to the VASO organizers in planning the state competition. This paper aims to provide a resource for other universities to support STEM activities in K–12 outreach organizations, like SciOly, in the future.

Abstract:
In recent years, Division I athletics programs have hired counseling or clinical psychologists as a resource for student-athletes who need assistance with clinical issues, personal difficulties, and performance issues. This article documents the evolution of this type of position at Virginia Tech and includes a discussion of the goals of the clinical sport psychologist position, an overview of the daily activities the position entails, and a discussion of the issues that comprise the assessment, conceptualization, and treatment of student-athlete concerns. Models for conceptualizing and delivering sport psychology interventions are also discussed. Evidence indicates that having access to a mental health professional familiar with the issues facing college athletes can be instrumental in helping many of these student-athletes achieve success in the university setting.

Abstract:
ABSTRACT Recycled shipping containers have the potential to be successfully used as a net-zero ready home. This study aims to evaluate the outcomes of a high-performance shipping container single-family housing project located in Virginia Beach, Virginia. The project was awarded the Best Undergraduate Project in the Single-family division at the 2019 U.S. Department of Energy's Solar Decathlon Design Challenge. The Hampton University Millennial Village Design Team designed a marketable net-zero ready container home for the ViBe Creative District in Virginia Beach, Virginia. Container Homes are not suitable for every homeowner, but they have a particular appeal to a generation of young and creative people across the country. For many municipalities in Virginia, where container housing is not readily accepted, the ViBe creative district has been having discussions with City code officials and local architects about the benefits. The Hampton University Millennial Village Design Team aimed to take advantage of the competition as an opportunity to explore a building construction method that is not widely seen in this part of the country. Testing design for net-zero readiness is a comprehensive way to understand how this type of construction performs from a building science standpoint. Collaboration with professional industry advisors helped the team to use research-based design methods to work on a unique project that the team believes will become a reality in the future. For the performance assessment of a net-zero container house, several simulation tools were used to investigate the environmental impacts, daylight performance, envelope performance, Energy Use Intensity (EUI), Home Energy Rating System (HERS), and solar energy generation. As for energy standards and codes, the Virginia residential code (VRC) 2015, International Energy Conservation Code (IECC) 2015 and The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) 90.1-2013 for residential buildings were consulted to set each variable for the net-zero container house project. The Rem/Rate energy simulation software achieved the HERS index of 51 and 0 without and with the applications of roof photovoltaics, respectively.

Abstract:
The study is an interpretative analysis of Virginia Cooperative Extension that examined the mission of the agency, as defined through its history and enabling acts of legislation. The study investigated how the mission has evolved during the eighty-four years of its existence. The study used the intent and context of the federal Smith-Lever legislation of 1914 as its benchmark to discover what the desired and anticipated outcomes were for Cooperative Extension by the original patrons of the legislation. Subsequent legislative acts at both the state and federal levels, as well as actions by the executive branch of government, were studied to discover if and when the mission of cooperative extension has changed and to identify the political, economic, and social factors that influenced the changes. The study incorporated accepted methods of historical research and included the review and analysis of both primary and secondary sources of information. Interviews of key leaders who have influenced the policy position of Virginia Cooperative Extension over the past thirty years were conducted. The data gathered by the study were analyzed and presented to highlight major themes that could have influenced critical policy issues that have confronted Virginia Cooperative Extension. The conclusion is that the mission of extension is two fold: (1) to provide education that could lead to increased economic opportunity and, (2) to enhance the quality of life enjoyed by Virginia’s citizens. Three critical attributes are identified that relate to the ability of Virginia Cooperative Extension to fulfill its mission: (1) access to research-based information, (2) a strong presence in local communities, and (3) a capacity to provide timely responses to emerging issues.<br>Ph.

Abstract:
The success of cooperative extension depends on the knowledge of how to apply the principles of extension education to situations where the activities are to be performed. The cooperative extension services dynamic localized approach to the solution of the common persons problem has stood the test of time. It is not necessary to establish a new system, but what is needed is to increase accountability and efficiency in the way programs are planned and developed. The overall purpose of this study was to develop criteria for assessing the local cooperative extension program planning process in Virginia. Specific objectives that served as a basis for accomplishing the overall purpose of the study were: 1. To identify principles that are basic for planning an effective local extension program. 2. To verify these principles with a panel of experts. 3. To formulate criteria, based on the verified principles, to assess if on-going local extension programs were developed following the accepted programming principles. 4. To field test the criteria to determine the degree to which the criteria are used as guides during the local extension program planning process. This study was a qualitative study. The principles identified and the criteria developed were reviewed by a panel of eight experts, then field tested in randomly selected extension units in the West Central Extension District of Virginia. Using personal interview methodology, unit directors of the randomly selected units were used for the field testing stage of this study. Six of the seven principles identified as basic for planning/developing effective local extension programs were accepted by the panel of experts. Eighteen criteria were formulated based on the accepted principles. Criteria as used in this study implies an overall description of a set of related actions and/or operations which will be called standards of the planning process. It was found that most of the unit directors in the West-Central Extension District of Virginia interviewed for this study use the criteria as guides during their respective programming process. The panel of experts and unit directors agreed that the criteria were important as guides for local extension programming processes. Based on the findings the author concluded that: (a) there are six essential principles for planning effective social extension programs; (b) that there are 18 criteria that can be used as guides for assessing if local extension programs are planned/developed using the essential extension program planning principles; and (c) that it is possible to assess local program planning activities in extension. A recommendation made from the study that the process of assessing local program planning activities be tested statewide to increase the usability potential of the criteria and give possible directions for statewide in-service needs of unit directors and extension agents.<br>Ed.

Logsdon, Susannah M. "The Incidence of Stress Fractures Among All Female Division I Athletes at Virginia Polytechnic Institute and State University." Thesis, Virginia Tech, 1999. http://hdl.handle.net/10919/42175.

Full text
Abstract:
Stress fractures are common overuse injuries that have plagued athletes for many years. Often referred to as fatigue fractures, they are formed when the skeletal muscles fatigue and can no longer absorb the shock of repetitive pounding activities such as running. Stress fractures are most common in the weight-bearing bones of the lower extremities and are usually preceded by sudden increases or changes in training routines. Because they are most common in athletes who are least fit, it has been hypothesized that freshmen athletes who are not prepared for the increased physical demands of college athletics have the greatest risk for developing stress fractures compared to other academic classes. As of yet however, there have been very few studies that have examined the interaction of different variables such as academic class, on the formation of stress fractures. Therefore, the purpose of this study was to look at the incidence, frequency and pattern of stress fractures among the female athletes at Virginia Polytechnic Institute and State University. A retrospective analysis of 28 injury cases over four years revealed that 67% of the injuries occurred in freshmen athletes. The majority of these were in the lower leg and occurred in mid-season rather than pre-season. There were no relationships found between the variables sport, class, site and season and thus it was concluded that the incidence of injury was not affected by the interaction of these variables. However, the variables themselves did influence the formation of stress fractures. Ultimately, this study provided insight on what factors should be carefully examined in order to prevent future stress fracture injuries in collegiate athletes.<br>Master of Science

Full text
Abstract:
Because the history of Indian-White relations in Canada has focussed mainly on the colonized Indians and ignored the impact of colonization on the White colonizers, it has simplified a complex affiliation which, clearly, had an impact on both groups while reducing Indian peoples to objects to be studied. By understanding the concept of a relationship involved in colonization, we can alternatively focus on the effects colonization had on both the large and small colonizers. Not only will a study of this type allow us to emphasize the once-ignored impact of colonization on the colonizers, it will also help to avoid the over-study of the Indian peoples in Canada. Exploring the history of the Indian Homemaking Program, Extension Division, University of Saskatchewan, 1967-1972 is an excellent venue in which to perform such a study. The program, which involves White Extension Instructors travelling to Saskatchewan reserves to teach Indian women homemaking skills such as knitting and crocheting, sewing and food preparation, promoted informal cross-cultural education in a setting that was both relaxed and enjoyable. After speaking with Extension Instructors about their vast array of experiences with respect to the program, it is abundantly clear that their days in the program, and with Indian women, changed the way they saw and experienced Saskatchewan.

Abstract:
碩士<br>龍華科技大學<br>商學與管理研究所<br>99<br>The decline of birth rates in Taiwan has worsened in recent years. Despite the decrease of schooling population year by year, the number of colleges is still on the increase, causing an imbalance of demands and supplies in highereducation. All colleges, particularly those offering extension education, are faced with more difficulties in recruiting students. The pass rate of the joint examination for four-year extension education programs and two-year night-division programs in northern Taiwan reached a record high of 78.20% this year. Under the promotion of lifelong learning by the Ministry of Education, universities in Taiwan are developing toward providing more diverse curriculums. This tendency also highlights the importance of further education programs for adult education. To attract more students, recruitment strategies become particularly important. In setting up recruitment strategies, students’ future needs and variation of their needs should be first understood. Hence, this study investigated the following issues: What are the factors determining college choice among students of four-year and two-year extension education programs? Is their school choice significantly affected by their jobs? What are the gender differences in common factors considered? Results showed that among the common factors determining college choice, “college’s overall performance and outstanding achievements” were most highly emphasized by students of four-year further education programs, followed by “promotion of recruitment information” and “people influencing college choice”. “Living functions” and “college ranking” were less important to them. For students of two-year extension education programs, “college’s overall performance and outstanding achievements” were also most important, followed by “promotion and advertisement of recruitment”, “job factors”, and “people influencing college choice”. They were less concerned about “living functions” and “school ranking” as well. In terms of gender differences among students studying in four-year extension education programs, female students were more influenced by “overall impression of the college”, “professors’ academic background and research capacity”, “teachers”, and “convenience of accessing the college” than male ones; male students were more influenced by “recruitment information on the radio”, “recruitment information on papers, bus banners, and overpass banners”, “recruitment information distributed by supplementary education providers”, and “telephone promotions” than female ones. Among students studying in two-year extension education programs, female students were more influenced by “college’s laboratory and research facilities”, “professors’ academic background”, “college’s honor of being designated to execute Teaching Excellence Projects”, “post-graduation career”, “recruitment information on papers” , “website of college”, “distance from home”, “convenience of accessing the college” , “the rank of college and department in university of science and technology”, and “the rank of college and department on the web”than male ones. “Friends” were more influential to male students than to female ones.

Abstract:
As a scientist, the Long-Term Ecological Research (LTER) program has been on my mind for more than three decades. As an educator, I have served in the classroom for 41 years. The merger of the physical and the ecological sciences was at the core of my teaching philosophy. As a science communicator, I informed the general public on issues of climate and climate change. As a collaborator, I found that understanding strengths and weaknesses in collaborative partnerships best ensures success. As a science leader, I served at the National Science Foundation (NSF) as the Director of the Division of Environmental Biology (DEB), established the Schoolyard LTER Program, and launched the National Ecological Observatory Network (NEON). My disciplinary background includes formal graduate education at the University of Wisconsin in meteorology, climatology, and paleoclimatology, as well as in oceanography and biology (mycology, botany, zoology, and genecology). As a postdoctoral fellow, my scientific identity was on track to culminate as a paleoclimatologist. As an assistant and associate professor, my identity morphed to include coastal geomorphology (Hayden et al. 1995). Finally, my experiences in the LTER program have vectored my career toward the interactions of climate and vegetation (Hayden 1998). My affiliation is with the Virginia Coast Reserve (VCR) site in the LTER program (1986–2014). As one of the founding principal investigators of the VCR site, I have served in subsequent renewals as its principal or co-principal investigator. Our site-based research plan focused on the Virginia Coast Reserve on Virginia’s eastern shore with a focus on the dynamics of the chain of 14 barrier islands, bounded by the entrance to the Chesapeake Bay to the south and Assateague Barrier Island to the north. This peninsula is 100 km in length by 20 km in width. Only the islands fronting the Mississippi delta are more dynamic in both the temporal and spatial domains.

Abstract:
As part of the Norfolk-Southern Railroad’s on-going investigation into fuel consumption reductions for their fleet of 3000 locomotives, the Center for Alternative Fuels, Engines and Emissions at West Virginia University conducted on-site locomotive engine performance and emissions measurements to characterize the performance, fuel consumption and emissions associated with fuel injectors from two injector suppliers. Emissions and fuel consumption were measured using the West Virginia University Transportable Locomotive Emissions Testing Laboratory, which was set up at the Norfolk-Southern Heavy Repair Facility in Roanoke, Virginia. The tests were conducted to evaluate potential emissions and fuel consumption differences between two fuel injector suppliers using an EMD GP38-2 locomotive equipped with a 2100 hp (1566 kW), 16-cylinder, EMD 16-645E engine. The test locomotive engine was freshly overhauled and certified to the EPA locomotive Tier 0 emissions standards. Emissions and fuel consumption measurements were conducted according to the Federal Test Procedures defined in the Code of Federal Regulations 40CFR Part 92 Subpart B [1]. The engine was first tested in the “as overhauled” configuration with the OEM fuel injectors to establish the baseline emissions and fuel consumption. The baseline FTP results confirmed that this locomotive was in compliance with the Federal Tier 0 emissions standards. The OEM specification fuel injectors were replaced with “Fuel Saver” injectors designed and manufactured by an aftermarket injector supplier referred to in this paper as Supplier B. The Supplier B injectors reduced fuel consumption on the average of 2–4% for each notch, except for Notch 4 and Low Idle. However, the Supplier B injectors increased the NOx levels by 20–30% for almost every notch, which is an expected result due to the improved combustion efficiency.

Abstract:
This study examines the dynamics of turbulent flow in the wake of a turning ship using the large eddy simulation (LES) technique. LES is applied in conjunction with a random flow generation (RFG) technique originally developed at West Virginia University to provide unsteady inflow boundary conditions. As the ship is turning, the effects of the Coriolis and centrifugal forces on vortical structures are included. The effects of the Coriolis force on the flow-field are assessed and a grid sensitivity study is performed. The predicted turbulence structures are analyzed and compared with the wake of a non-turning ship.

Abstract:
Diesel Particulate Filters (DPFs) are well assessed aftertreatment devices, equipping almost every modern diesel engine on the market to comply with today’s stringent emission standards. However, an accurate estimation of soot loading, which is instrumental to ensuring optimal performance of the whole engine-after-treatment assembly is still a major challenge. In fact, several highly coupled physical-chemical phenomena occur at the same time, and a vast number of engine and exhaust dependent parameters make this task even more daunting. This challenge may be solved with models characterized by different degrees of detail (0-D to 3-D) depending on the specific application. However, the use of real-time, but accurate enough models, may be of primary importance to face with advanced control challenges, such as the integration of the DPF with the engine or other critical aftertreatment components (Selective Catalytic Reduction (SCR) or other NOx control components), or to properly develop model-based OBD sensors. This paper aims at addressing real time DPF modeling issues with special regard to key parameter settings, by using the 1D code ExhAUST (Exhaust Aftertreatment Unified Simulation Tool), developed jointly by the University of Rome Tor Vergata and West Virginia University. ExhAUST is characterized by a novel and unique full analytical treatment of the wall that allows faithful representation with high degree of detail the evolution of soot loading inside the porous matrix. Numerical results are compared with experimental data gathered at West Virginia University (WVU) engine laboratory using a Mack heavy-duty diesel engine coupled to a Johnson Matthey CCRT (DOC, Diesel Oxidation Catalyst+CDPF, Catalyzed DPF) aftertreatment system. To that aim, the engine test bench has been equipped with a DPF weighing setup to track soot load over a specifically developed engine operating procedure. Obtained results indicate that the model is accurate enough to capture soot loading and back pressure histories with regard to different steady state engine operating points, without needing any tuning procedure of the key parameters. Thus, the use of ExhAUST for application to advanced after-treatment control appears promising at this stage.

Abstract:
Crowd noise levels in large stadiums are often discussed in the press and by the casual stadium patron; however, there has been little scientific evaluation of these levels and their corresponding effects. An effort was undertaken at Penn State University to measure noise on the field at Beaver Stadium (State College, PA: capacity 107,282) during a PSU football game. The two-fold purpose of these measurements was to evaluate the noise levels with respect to how they affect the game and make real-time, calibrated recordings for future use in the football team’s indoor practice facility. Measurements were taken on the field level using sound levels meters and DAT recorders throughout the PSU vs. Ohio State University football game on 27 October 2007. As a point of comparison, similar measurements were conducted by a team of researchers from Virginia Tech during the VT vs. University of Miami game on 17 November 2007 at Lane Stadium (Blacksburg, VA: capacity 66,233). The crowd noise levels are compared between the two stadiums taking into account the circumstances of the two games, time of day, and design of the stadiums. The levels on the field are evaluated in terms of speech intelligibility, i.e. the ability of the players to communicate with each other. In addition, a hearing loss safety assessment for both fans and players is presented.

Abstract:
Over the past few decades there has been considerable progress made in understanding the processes leading to formation and evolution of particulate matter (PM) emissions from heavy duty diesel engines (HDDE). This progress has been primarily made under controlled laboratory conditions with the use of constant volume sampling (CVS) systems and to a limited extend through on-road chase studies. West Virginia University (WVU) is attempting to close the present knowledge gap by conducting detailed experiments in a custom designed and constructed environmental wind tunnel. The understanding and knowledge has recently been further extended to new emission reduction technologies, such as the diesel particulate filter (DPF) which has dramatically changed the size distribution and chemical composition of PM. Additionally, the selective catalytic reduction (SCR) technology has shown to further enhance the formation of nucleation mode particles as well as alter their morphology. Even with advances in technology there remains a considerable gap in the current level of understanding of PM formation and evolution, since the combustion generated PM from diesel engines is not discernible from the atmospheric background PM measured beyond 300m from highways. After being emitted from the vehicle exhaust system, the process of dilution in the atmosphere leads to a multitude of PM transformation phenomena, such as volatilization, coagulation, and condensation. The work presented herein has been divided into two parts which are published separately from each another. The first part describes the design and commissioning process of the wind tunnel focusing on both, aerodynamic and structural constraints, which ultimately led to the definition of the main characteristics of the facility. The resulting design is a subsonic, non-recirculating, suction type tunnel, with a 16ft high and 16ft wide test section capable of housing a full-size heavy-duty tractor cab. A 2,200hp suction fan is employed to provide up to 80 mph wind speeds. The 115ft test cell length guarantees for a 2 second residence time for the exhaust plume evolution (at 35 mph) and complies with turbulence intensity (less than 1%) and quality flow requirement as identified for this type of application. In addition, the West Virginia University (WVU) wind tunnel has been equipped with a custom made sampling system able to move in all three dimensions in order to measure spatially resolved plume characteristics. The second part will describe the actual test procedures and the experimental results and will be published in a separate paper.

Abstract:
A linear engine/alternator was simulated and designed, and a prototype was built at West Virginia University. This paper describes the engine and presents original operational data. The linear engine was a two-cylinder, two-stroke, common rail direct injection, compression ignition engine. The engine was built using off the shelf components to reduce cost where it was possible. Engine control, injection duration and timing, were achieved using a microcontroller with piston position as a control input. Experiments on the engine were performed to study its behavior. The studied variables included mass of the translator, amount of fuel injected, injection timing, load, and stroke with operating frequency and mechanical efficiency as the basis of comparison. At this point of development, the engine was far from optimized; however, the trends in engine behavior were clear. Increasing the translator mass resulted in decreased operating frequency. Increasing the stroke length also resulted in decreased operating frequency. Overcharging and increased fueling rate, both, resulted in increased power output, efficiency, and operating frequency. Advancing injection timing resulted in increased frequency, efficiency and power output, and decreased stalling frequency. This suggests that the engine operated in an HCCI-like fashion.

Abstract:
Despite their overwhelming popularity and widespread use, diesel engines have to strive to meet the continually tightening emission regulations. One of the most effective methods to control diesel particulate matter (PM) emissions from heavy duty diesel engines is to use wall flow Diesel Particulate Filters (DPFs). It is still a major challenge to get an accurate estimation of soot loading, which is crucial for the engine aftertreatment assembly optimization. In the recent past, several advanced computational models of DPF filtration and regeneration have been presented to assess the cost effective optimization of future particulate trap systems. In this study, the already presented 1D code [1,2] was extended to understand the impact of 2D representation to predict the transient behavior of a catalyzed Diesel Particulate Filter (CDPF). Quasi-steady state conservation of mass and momentum was solved to find the flow velocity and a previously validated, advanced filtration/regeneration model allowed a highly detailed representation of the soot loading, permeability, porosity and filtration efficiency. Results are presented in terms of comparison with the 1D code, over FTP engine transient cycle data gathered at the West Virginia University Engine and Emissions Research Laboratory (WVU-EERL), by keeping constant parameter set, for the sake of general validation of simplifying assumptions of the 1D code. Results generally state that the ID representation is effective toward PM loading prediction, although presenting considerable axial effects at higher DPF temperature.

Abstract:
A Hybrid Projectile (HP) currently under design at West Virginia University was simulated to estimate the effects of barrel launch angle and flight position of wing deployment. The projectile is similar to a standard 60mm mortar, except that is has been equipped to achieve extended range. A Simulink model was developed based upon external ballistics. The flight performance of the WVU-HP-60 was compared to a standard M720 60mm mortar. The developed HP was considered to be a tube-launched UAV, that transforms, not directly after launch but sometime after for optimal gliding, and must be modeled with different flight profiles because after transformation the aerodynamics drastically change. Two models of the UAV were created to allow for design of controllers. They were the launch model and the projectile flight model. It was found that the projectile may exit the barrel with a two degree variation of launch angle. The simulations show that range extension is still viable, with this barrel exit variation, to within 10% of the maximum achievable range. A confidence area was also developed to determine how far the launch angle and wing deployment position could stray and still maintain a significant amount of range extension.

Abstract:
Increasing urban pollution levels have led to the imposition of evermore stringent emissions regulations on heavy-duty engines used in transit buses. This has made compressed natural gas (CNG) a promising fuel for reducing emissions, particularly particulate matter (PM) from heavy-duty transit buses. Indeed, research studies performed at West Virginia University (WVU) and elsewhere have shown that pre-2010 compliant natural gas engines emit an order of magnitude lower PM emissions, on a mass basis, when compared to diesel engines without any exhaust aftertreatment devices. However, on a number basis, particle emissions in the nanoparticulate range were an order of magnitude higher for natural gas fueled buses than their diesel counterparts. There exists a significant number of pre-2007 CNG powered buses in transit agencies in the US and elsewhere in the world. Therefore, an exhaust aftertreatment device was designed and developed by WVU, in association with Lubrizol, to retrofit urban transit buses powered by MY2000 Cummins Westport C8.3G+ heavy-duty CNG engines, and effectively reduce Toxic Air Contaminants (TAC) and PM (mass and number count) exhaust emissions. The speciation results showed that the new exhaust aftertreatment device reduced emissions of metallic elements such as iron, zinc, nonmetallic minerals such as calcium, phosphorus and sulfur derived from lube oil additives to non-detectable levels, which otherwise could contribute to an increase in number count of nanoparticles. The carbonyl compounds were reduced effectively by the oxidation catalyst to levels below what were found in the dilution air. Also, hydrocarbons identified as TAC’s by California Air Resource Board (CARB) [1] were reduced to non-detectable levels. This ultimately reduced the number of nanoparticles to levels equal to that found in the dilution air.

Abstract:
In 2006, the ports of Long Beach and Los Angeles adopted the final San Pedro Bay Ports Clean Air Action Plan (CAAP), initiating a broad range of programs intended to improve the air quality of the port and rail yard communities in the South Coast Air Basin. As a result, the Technology Advancement Program (TAP) was formed to identify, evaluate, verify and accelerate the commercial availability of new emissions reduction technologies for emissions sources associated with port operations, [1]. Container drayage truck fleets, an essential part of the port operations, were identified as the second largest source of NOx and the fourth largest source of diesel PM emissions in the ports’ respective 2010 emissions inventories [2, 3]. In response, TAP began to characterize drayage truck operations in order to provide drayage truck equipment manufacturers with a more complete understanding of typical drayage duty cycles, which is necessary to develop emissions reduction technologies targeted at the drayage market. As part of the broader TAP program, the Ports jointly commissioned TIAX LLC to develop a series of drayage truck chassis dynamometer test-cycles. These cycles were based on the cargo transport distance, using vehicle operational data collected on a second-by-second basis from numerous Class 8 truck trips over a period of two weeks, while performing various modes of typical drayage-related activities. Distinct modes of operation were identified; these modes include creep, low-speed transient, high-speed transient and high-speed cruise. After the modes were identified, they were assembled in order to represent typical drayage operation, namely, near-dock operation, local operation and regional operation, based on cargo transport distances [4]. The drayage duty-cycles, thus developed, were evaluated on a chassis dynamometer at West Virginia University (WVU) using a class 8 tractor powered by a Mack MP8-445C, 13 liter 445 hp, and Model Year (MY) 2011 engine. The test vehicle is equipped with a state-of-the-art emissions control system meeting 2010 emissions regulations for on-road applications. Although drayage trucks in the San Pedro Bay Ports do not have to comply with the 2010 heavy-duty emissions standards until 2023, more than 1,000 trucks already meet that standard and are equipped with diesel particulate filter (DPF) and selective catalytic reduction (SCR) technology as used in the test vehicle. An overview of the cycle evaluation work, along with comparative results of emissions between integrated drayage operations, wherein drayage cycles are run as a series of shorter tests called drayage activities, and single continuous drayage operation cycles will be presented herein. Results show that emissions from integrated drayage operations are significantly higher than those measured over single continuous drayage operation, approximately 14% to 28% for distance-specific NOx emissions. Furthermore, a similar trend was also observed in PM emissions, but was difficult to draw a definite conclusion since PM emissions were highly variable and near detection limits in the presence of DPF. Therefore, unrepresentative grouping of cycle activity could lead to over-estimation of emissions inventory for a fleet of drayage vehicles powered by 2010 compliant on-road engines.
