My Experience With Tularemia

On October 13, 1939 (Friday), I was doing routine autopsy work on cottontail rabbits at the Zoological Laboratory, University of Wisconsin. The rabbits were box trapped at the University Arboretum, brought in alive to the laboratory, and later killed for endocrine and parasitological studies. The handling of wild rabbits called for care, so all necessary precautions were taken; such as rubber gloves, disinfection, and careful disposal of the carcasses

Student Views on the Flexible Delivery of the IS \u2797 Curriculum

The growth in availability of the Internet permits a greater variety in the delivery of the IS curriculum than was hitherto possible. This paper examines the various delivery techniques that might be employed in a typical university IS course, and comments on these from the standpoint of student preference. In spite of the technological basis for much information systems study, and their exposure to novel teaching methods like videoconferencing and the World Wide Web, students still prefer traditional teaching techniques like lectures, problem solving/discussion classes and practicals. Opting for modern teaching technologies to deliver all or part of the IS curriculum will need careful planning if potential student resistance is to be overcome

Avoiding Contract Audit Citations by Improving Billing Submissions

In this session, INDOT auditors address common billing errors for different contract payment methodologies. Attendees responsible for preparing bills and submitting invoices will gain a better understanding of how contracts are designed and what is accepted for payment. Local agencies will understand how to review a consultant’s billing before making payment, thus avoiding citations. This presentation should be of particular interest to both engineering consulting firms and local agencies who do business with INDOT

Closing the College Graduation Gap: National College Access and Success Benchmarking Report

This report, the first of an annual series, establishes meaningful metrics about the outcomes of students served by college access and success programs. Using data collected from 24 college access programs, enrollment and graduation rates for the high school classes of 2007, 2008, and 2009 and an enrollment rate for the high school class of 2013 are calculated. Students served by college access and success programs outperform expectations for college enrollment and completion, demonstrating that current national lower levels of postsecondary attainment for poor and minority students are not destiny. These results support the conclusion that college access and success programs are making progress toward closing the college knowledge, opportunity, and completion gaps for the students they serve

The Occurrence of \u3ci\u3eContracaecum travassosi\u3c/i\u3e (Nematoda) in North America [Research Notes]

Seven specimens of a nematode (five males and two females) of the genus Contracaecum were collected from the ventriculus of Pandion haliaetus carolinensis (Gmelin) (osprey) captured at Greenville, Ohio. After a comparison with C. travassosi described by Gutierrez (1943. Sobre la morfología de una nueva especie de Contracaecum (Nematoda: Ascaroidea) Rev. Brasil. Biol. 3: 159-172) from the cormorant (Phalacrocorax albiventer) collected at the San Jose light-house, Territory of Chubut, Argentina, our material has been assigned to that species. So far as the writers have been able to determine, this is the first record of the species from North America and since description of the species is available in North American literature a brief description is presented

Evolving Maturation of the Series-Bosch System

Human exploration missions to Mars and other destinations beyond low Earth orbit require highly robust, reliable, and maintainable life support systems that maximize recycling of water and oxygen. In order to meet this requirement, NASA has continued the development of a Series-Bosch System, a two stage reactor process that reduces carbon dioxide (CO2) with hydrogen (H2) to produce water and solid carbon. Theoretically, the Bosch process can recover 100% of the oxygen (O2) from CO2 in the form of water, making it an attractive option for long duration missions. The Series Bosch system includes a reverse water gas shift (RWGS) reactor, a carbon formation reactor (CFR), an H2 extraction membrane, and a CO2 extraction membrane. In 2016, the results of integrated testing of the Series Bosch system showed great promise and resulted in design modifications to the CFR to further improve performance. This year, integrated testing was conducted with the modified reactor to evaluate its performance and compare it with the performance of the previous configuration. Additionally, a CFR with the capability to load new catalyst and remove spent catalyst in-situ was built. Flow demonstrations were performed to evaluate both the catalyst loading and removal process and the hardware performance. The results of the integrated testing with the modified CFR as well as the flow demonstrations are discussed in this paper

Potential Spawning Strategy and Fecundity of Alabama Shad (Alosa alabamae) from the Apalachicola River, Florida

Alabama shad (Alosa alabamae), classified as a Species of Concern by the National Marine Fisheries Service, are native to the northern Gulf of Mexico drainages. Our study estimated the fecundity of 39 female Alabama shad from the Apalachicola River, Florida. Individuals ranged in age from 2-4 years with an average weight of 729 g. Samples (1 g) were cut from the center of each ovary, and oocytes present were counted. Diameters of 50 randomly-sampled oocytes were measured per sample. Oocyte diameters ranged from 0.3-2.7 mm, with a mode of 1.5 mm. The unimodal oocyte diameter percent frequency distribution suggests that Alabama shad spawn multiple times in a spawning season. Total mean ovary weight was 67.88 ± 25.90 (s.d.) g/individual, with average annual fecundity estimated to be 79,420 ± 26,896 (s.d.) oocytes/individual. Our results were consistent with previous Alabama shad fecundity studies out of the Apalachicola River

Space Launch and Reentry Operations Collaborative Decision Making (CDM) Concept

The Federal Aviation Administration’s Air Traffic Organization manages the National Airspace System (NAS) for all users. Demand for this airspace is growing as space launch and reentry (L/R) operations increase in number, vehicle and mission types, and locations. Collaborative Decision Making (CDM) is a well-established practice for resolving airspace demand issues among multiple NAS users as it considers multiple stakeholders’ perspectives to make informed decisions. The MITRE Corporation is conducting research on how CDM principles can be applied to L/R operations and has developed an initial Space CDM concept. Our paper describes this concept, including high-level operational elements and supporting technology capabilities. In the concept, collaboration and data exchange inform decision-making during preliminary mission planning, airspace scheduling, airspace management, and real-time operations. Post-operations analysis is performed and feedback provided to improve decision making. This gives L/R operators information on airspace congestion as they consider options for launch and reentry locations and times. Airspace management planning to address airspace congestion considers mission flexibilities and constraints provided by operators. Real-time air traffic management is more dynamic due to increased certainty provided by L/R operational status updates. Through CDM participation, L/R operators have a voice in how airspace demand is managed and in prioritizing processes, information sharing, and capabilities to improve operations. NAS users experience less uncertainty and more predictability of access and schedules through new information exchanges and collaborative processes. This research began in fiscal year (FY) 2018 and continues in FY19 with concept socialization, feedback, expansion, and refinement
