The awesome power of a military convoy in Vietnam can also be a danger. Articles, stories, and other compositions in this archive were written by participants in the Mighty Pen Project. The program, developed by author David L. Robbins, and in partnership with Virginia Commonwealth University and the Virginia War Memorial in Richmond, Virginia, offers veterans and their family members a customized twelve-week writing class, free of charge. The program encourages, supports, and assists participants in sharing their stories and experiences of military experience so both writer and audience may benefit

Observation and Modeling of Source Effects in Coda Wave Interferometry at Pavlof Volcano

We examine seismic records of repeating explosions from Pavlof volcano, Alaska, during its 2007 eruption. Repetitive explosions are typical of Strombolian-style eruptions and allow measurement of relative time shifts between similar late-arriving phases using the technique called coda wave interferometry (Snieder et al., 2002). The measurements enable the detection of small changes in the volcanic interior of Pavlof. We are able to resolve an increase in the relative traveltime change of late-arriving seismic waves on the order of 0.3% over the course of two weeks. Based on the spectra of the explosions, their location inside the magma conduit, previous studies of Pavlof volcano, and 3D seismic modeling, we argue the most likely scenario is one in which the velocity and/or the geometry of the conduit changes. This demonstrates the sensitivity of coda wave interferometry to source effects, in addition to path effects, at volcanoes

Truck Route Access Evaluation: United Parcel Service, Standiford Field Louisville Airport, and Ford Motor Company, Louisville, Site #6

This is a study undertaken on behalf of the Kentucky Transportation Cabinet (KYTC). There are two main objectives of the Freight Movement and Intermodal Access in Kentucky Study (SPR 98-189): 1) evaluation of the access for trucks between intermodal or other truck generating sites and the National Highway System (NHS); and 2) furthering the understanding of freight commodity flows throughout the state. This report summarizes the access evaluation for the areas around the Standiford Field Louisville Airport. This includes two large generators off of Fern Valley Road: Ford Motor Company and the United Parcel Service. These sites are located in Jefferson County in the KlPDA Area Development District (ADD) and KYTC Highway District #5. The location of the site and routes is shown in Figure 1. Smaller industries to the west of the airport field along Crittendon Avenue include Akzo Nobel Trucking, General Electric Supply, KT Shannon Lumber Company, Airside Commerce Center, United Catalyst Incorporated, and Rapid Runner Warehousing. Work on other specific sites throughout Kentucky as well as the freight commodity flow task is ongoing and documented elsewhere. The sites to be evaluated in this study were selected from two existing databases (a truck facility survey from 1994 and the intermodal facility inventory) based on ADD and KYTC Highway District planner recommendations, geographic location, distance to the NHS, and the number of trucks accessing the site. Consideration was also made for the freight type handled and transportation modes used. The site was visited for video recording on November 21, 1998, data collection on September 29, 1998 and intersection traffic counts on December 15, 1998. The facilities are located south of I-264 and west of I-65 in Louisville either on or adjacent to the airport facility. The surrounding area is generally urban and fairly commercial / industrial. A phone survey was conducted with a UPS facility manager early in the study process. The survey found that approximately 150 trucks per day normally access the site with as many as 400 in the peak of the year. The most common truck is a 28-foot drop van but trucks as large as 53-foot semi-trailers also access the site. No traffic congestion problems were raised. Attempts to contact other large truck generators in the area were unsuccessful. The phone survey is in Appendix A

Truck Route Access Evaluation: Logan Aluminum Russellville - Logan County, Site #2657

The Freight Movement and Intermodal Access in Kentucky Study (SPR 98-189) is being conducted by the Kentucky Transportation Center on behalf of the Kentucky Transportation Cabinet. There are two main objectives of the study: 1) evaluation of the access for trucks between intermodal or other truck generating sites and the National Highway System (NHS) and 2) furthering the understanding of freight commodity flows throughout the state. This report summarizes the access evaluation for a facility located in Logan County in the Barren River Development District (ADD) and KYTC Highway District# 3. The location of the site is shown in Figure 1. Work on other specific sites as well as the freight commodity flow task is ongoing and is documented elsewhere. The sites to be evaluated were selected from two existing databases (a truck facility survey from 1994 and the intermodal facility inventory) based on ADD and KYTC Highway District planner recommendations, geographic location, distance to the national highway system, and the number of trucks accessing the site. Consideration was also made for the freight type handled and transportation modes used. This site is located on US 431 in Logan County. The National Highway System route serving the area is US 68 shown in Figure 1. A phone survey was conducted with the facility truck routing personnel early in the study process. The site was visited on October 26, 1998 for data collection and December 5, 1998 for video recording. The only facility in the area is Logan Aluminum located on US 431 north of Russellville. The approximate location is also shown in Figure 1. The surrounding area is generally rural and agricultural. The phone survey found approximately 200 trucks per day accessing this site (in and out), while HIS data indicates 720 trucks per day travel along US 431. The site trucks are generally flatbed truck 45-48 feet in length. The phone survey information can be found in Appendix B. A concern mentioned in the phone survey was the absence of a southern bypass around Russellville. The Six Year Highway Plan includes the design for construction of a southern bypass. Also included in the Six Year Highway Plan is a project to widen a section of US 431 from near Logan Aluminum to north of the Russellville Bypass

Truck Route Access Evaluation: Seaboard Farms, Graves County, Site #2623

The Freight Movement and Intermodal Access in Kentucky Study (SPR 98- 189), undertaken by the Kentucky Transportation Center (KTC) on behalf of the Kentucky Transportation Cabinet (KYTC), has two main objectives: 1) the evaluation of access for trucks between intermodal or other truck generating sites and the National Highway System (NHS) and 2) furthering the understanding of freight commodity flows throughout the state. This report summarizes the access evaluation for one facility located in Graves County in the Purchase Area Development District (ADD) and KYTC Highway District #1. The location of the site is shown in Figure 1. Work on other specific sites as well as the freight commodity flow task are on-going and are documented elsewhere. The sites to be evaluated were selected from two existing databases (a truck facility survey from 1994 and the intermodal facility inventory) based on ADD and Kentucky Transportation Cabinet (KYTC) planner recommendations, geographic location, distance to the National Highway System, and the number of trucks accessing the site. Consideration was also made for the freight type handled and transportation modes used. The facility for study is Seaboard Farms, and the initial trip to the site revealed that there were no other significant sources of truck traffic in the vicinity. The site was visited for route videotaping on January 15, 1 998 and data collection on August 3, 1 998. Phone surveys were conducted early into the study process so that facility managers could indicate the truck routes and provide insight into potential access-limiting issues. The phone survey, which is included in Appendix A, indicated that approximately 65 trucks per day (130 one-way trips) are accessing the site. The largest trucks using the access route are 58-foot semi-trailers with 42-foot semi-trailers being the most common
