A computer program for calculating design and off-design performance for turbojet and turbofan engines
Program uses component performance maps to enable user to do analytical engine cycle calculations. Through scaling procedure, each of the component maps can be used to represent a family of maps. Either convergent or convergent-divergent nozzles may be used

2019-nCoV: The Identify-Isolate-Inform (3I) Tool Applied to a Novel Emerging Coronavirus
2019 Novel Coronavirus (2019-nCoV) is an emerging infectious disease closely related to MERS-CoV and SARS-CoV that was first reported in Wuhan City, Hubei Province, China in December 2019. As of January 2020, cases of 2019-nCoV are continuing to be reported in other Eastern Asian countries as well as in the United States, Europe, Australia, and numerous other countries. An unusually high volume of domestic and international travel corresponding to the beginning of the 2020 Chinese New Year complicated initial identification and containment of infected persons. Due to the rapidly rising number of cases and reported deaths, all countries should be considered at risk of imported 2019-nCoV. Therefore, it is essential for prehospital, clinic, and emergency department personnel to be able to rapidly assess 2019-nCoV risk and take immediate actions if indicated. The Identify-Isolate-Inform (3I) tool, originally conceived for the initial detection and management of Ebola virus and later adjusted for other infectious agents, can be adapted for any emerging infectious disease. This paper reports a modification of the 3I tool for use in the initial detection and management of patients under investigation for 2019-nCoV. After initial assessment for symptoms and epidemiological risk factors, including travel to affected areas and exposure to confirmed 2019-nCoV patients within 14 days, patients are classified in a risk-stratified system. Upon confirmation of a suspected 2019-nCoV case, affected persons must immediately be placed in airborne infection isolation and the appropriate public health agencies notified. This modified 3I tool will assist emergency and primary care clinicians, as well as out-of-hospital providers, in effectively managing persons with suspected or confirmed 2019-nCoV
EVA-glass interface bond stability
The ethylene vinyl acetate/glass interface bond stability was investigated. Special methods to determine the structure of polymer/glass interface were developed. Structural changes related to hydrothermal degradation of polymer/glass interface are examined. Methods to inhibit the degradation reaction which occur at polymer/glass interface are developed
From the Woman's Viewpoint: Ethical Dilemmas Confronted by Women as Informal Caregivers of Frail Elders
Copyright 2004 Alliance for Children and FamiliesWomen as informal caregivers face complex ethical dilemmas in caring for a frail elder. Through indepth
interviews with 13 ethnically diverse caregivers, this qualitative study explored women's ethical
decision-making. Focus group interviews of home health staff, key informant caregivers, and interviewees
provided guidance for research design, reflection on findings and development of implications.
Findings are integrated into an ethical decision-making model that includes types of ethical
dilemmas (e.g., protection of life vs. autonomy); feelings that permeate decision making (e.g., fear);
processes for addressing ethical dilemmas (e.g., family collaboration); and supportive services.
Implications include (a) expansion of services to meet caregivers' ongoing needs, (b) research that
acknowledges multiple decision-making components, and (c) the use of caregiving vignettes in the
classroom
Diamonds as timing detectors for MIP: The HADES proton-beam monitor and start detectors
This paper gives an overview of a recent development of measuring time of
flight of minimum-ionizing particles (MIP) with mono-crystalline diamond
detectors. The application in the HADES spectrometer as well as test results
obtained with proton beams are discussed.Comment: submitted to Nuclear Instruments and Methods
ANALYSIS OF BORROWER AND LENDER USE OF INTEREST ASSISTANCE ON FSA GUARANTEED FARM LOANS
The Farm Security and Rural Investment Act of 2002 made permanent the interest assistance program for the Farm Service Agency's guaranteed loans, authorized a significant increase in funding for the program, and targeted funding for beginning farmers and ranchers. The research presented here provides a basic descriptive analysis of past use. In particular, borrower data for Federal fiscal years 1985 through 2002 are examined in several dimensions. These dimensions include geographic, borrower type, lender type, interest rate differentials, percent guarantee, and the status of the loan as to whether a loss claim was paid or the loan remained active. Even though the program has been in existence for more than 15 years, little is known about its impact and utilization. This research is an initial step in documenting usage of the program.Agricultural and Food Policy, Agricultural Finance,
