PAN AIR analysis of the NASA/MCAIR 279-3: An advanced supersonic V/STOL fighter/attack aircraft

PAN AIR is a computer program for predicting subsonic or supersonic linear potential flow about arbitrary configurations. The program was applied to a highly complex single-engine-cruise V/STOL fighter/attack aircraft. Complexities include a close-coupled canard/wing, large inlets, and four exhaust nozzles mounted directly under the wing and against the fuselage. Modeling uncertainties involving canard wake location and flow-through approximation through the inlet and the exhaust nozzles were investigated. The recently added streamline capability of the program was utilized to evaluate visually the predicted flow over the model. PAN AIR results for Mach numbers of 0.6, 0.9, and angles of attack of 0, 5, and 10 deg. were compared with data obtained in the Ames 11- by 11-Foot Transonic Wind tunnel, at a Reynolds number of 3.69 x 10 to the 6th power based on c bar

Assessing Student Exposure to and Use of Computer Technologies through an Examination of Course Syllabi

A syllabus analysis instrument was developed to assist program evaluators, administrators and faculty in the identification of skills that students use as they complete their college coursework. While this instrument can be tailored for use with a variety of learning domains, we used it to assess students\u27 use of and exposure to computer technology skills. The reliability and validity of the instrument was examined through an analysis of 88 syllabi from courses within the teacher education program and the core curriculum at a private Midwest US university. Results indicate that the instrument has good inter‐rater reliability and ratings by and interviews with faculty and students provide evidence of construct validity. The use and limitations of the instrument in educational program evaluation are discussed

Black Holes in AdS/BCFT and Fluid/Gravity Correspondence

A proposal to describe gravity duals of conformal theories with boundaries (AdS/BCFT correspondence) was put forward by Takayanagi few years ago. However interesting solutions describing field theories at finite temperature and charge density are still lacking. In this paper we describe a class of theories with boundary, which admit black hole type gravity solutions. The theories are specified by stress-energy tensors that reside on the extensions of the boundary to the bulk. From this perspective AdS/BCFT appears analogous to the fluid/gravity correspondence. Among the class of the boundary extensions there is a special (integrable) one, for which the stress-energy tensor is fluid-like. We discuss features of that special solution as well as its thermodynamic properties.Comment: 18 pages, 4 figures (7 pdf-files).

Digital Ethnography for Intercultural Professional Communication: Some Best Practice Principles

With global compressions of time and space, intercultural contact is heightening. Digital networks are converging. Perhaps more than ever before, professional communicators require cultural and technical savvy, allowing them to navigate, in a principled manner, digitally-mediated contexts (Spilka, 2010). Since no mediation is value neutral, digital technologies can spark intercultural friction (Thatcher, 2004; Warshauer, 2003, p. 6), blur ethical codes (Capurro, 2008; Himma, 2008), and perpetuate colonial relations (Ess & Sudweeks, 2012, p. xvi). How to operate in such complex, power-laden environments is a central concern in intercultural professional communication (IPC) and merits additional inquiry

The Gospel in Singapore - The Impact of Civil Religion and Civil Law

Madson, Mark, J. “The Gospel in Singapore: The Impact of Civil Religion and Civil Law.” Ph.D. diss., Concordia Seminary, 2015. 240 pp. The author explores the development of civil religion in the Republic of Singapore, paying special attention to its sources in English common law, Confucianism, and the Peoples’ Action Party (PAP) ideology of economic pragmatism. Colonial and modern civil religious law, including the Maintenance of Religious Harmony Act of 1990, serve as the basis for analyzing the interaction of the state and traditional religious traditions. The Singapore Story, as told by Lee Kuan Yew and the PAP, provides a narrative context for interpreting the terms of Singaporean civil religion. The concepts of harmony and self-cultivation are explored within traditional Confucianism and civil religion. The active righteousness of this civil religion is then compared and contrasted with the passive or spiritual righteousness of Christianity using confessional Lutheran theology. Because civil righteousness is promoted by an authoritarian government so pervasively, it puts at risk a proper understanding of Christian righteousness. Therefore, the Church must respond to civil religion with a public theology. The narrative of this theological response includes distinguishing the passive righteousness of faith from all other forms of righteousness. This public theology need not attempt to Christianize law and society but it must clearly delineate the dual rule of God and the created orders which take on a unique form in Singapore. Finally, some considerations of the limits of obedience to political authority and the direction of service within the orders of Singaporean life are outlined

Vertical transmission of porcine circovirus type 2 in breeding herds

Porcine circovirus type 2 (PCV2) impacts global swine production, is economically important, and is associated with multiple disease entities that include multisystemic disease, wasting, pneumonia, diarrhea and reproductive failure. Transmission of PCV2 within or between swine populations is not well understood. We characterized semen shedding of PCV2a and PCV2b in Landrace boars and found that PCV2 viremia precedes semen shedding, clinical signs are absent, and peak PCV2 semen shedding occurs between 10-20 days post-infection. PCV2 can be continuously shed in semen for at least 90 days. We determined that PCV2 shed in semen is infectious when used in a swine bioassay model, but dam or fetal infection after artificial insemination with PCV2 positive extended semen does not necessarily occur. However, when nayve dams were artificially inseminated with PCV2-spiked semen, dam viremia and fetal infection occurred. Nayve dams inseminated with spiked semen did not show clinical signs of infection after PCV2 exposure, but increased numbers of mummified and stillborn fetuses were observed. Stillborn fetuses exhibited gross lesions of heart failure and myocardial tissue was determined to be the best sample for diagnosing in utero PCV2 infection. Using the PCV2-spiked semen model, we compared dam immunity associated with PCV2 vaccination to immunity associated with a previous infection to induce protection against subsequent PCV2-challenge. PCV2 antibodies induced by a homologous strain of PCV2 protected against in utero infection; however, 63% of the piglets from vaccinated dams were PCV2 viremic at birth suggesting that commercial vaccines may not prevent fetal infection. We also verified that PCV2 vaccination of dams is not protective against fetal infection following oro-nasal challenge during gestation, and affirmed that immunocompetent in utero fetuses are able to clear PCV2 infection prior to parturition

Of All the Cities

OF ALL the cities, there is none like London. The streets are wet brick, and there are little fog-bound squares and alleys. There are hidden chimes that strike out through the dark and rain, and everything is secret..
