Within the NASA Aviation Systems Capacity Program, the Terminal Area Productivity (TAP) Project is addressing airport capacity enhancements during instrument meteorological conditions (IMC). The Airborne Information for Lateral Spacing (AILS) research within TAP has focused on an airborne centered approach for independent instrument approaches to closely spaced parallel runways using Differenti...

The purpose of this study was to systematically review the instruments used to obtain anesthesia-specific patient satisfaction data and to determine the degree to which each instrument controlled for measurement error bias, such as poor survey design. By using an assessment and evaluation tool developed for the present study that held proven internal reliability and construct validity, we analy...

This paper presents some aspects related to the issues of aggregating economic indicators. Departing from the research of Gh. Paun (1983) we will prove a theorem which states that under certain, natural assumptions, it is impossible to obtain an optimum aggregation. Unlike the original work of Paun, in this paper we are giving a rather simple proof of this theorem.

The validity of the Michaelis-Menten-Briggs-Haldane approximation for single enzyme reactions has recently been improved by the formalism of the total quasi-steady-state approximation. This approach is here extended to fully competitive systems, and a criterion for its validity is provided. We show that it extends the Michaelis-Menten-Briggs-Haldane approximation for such systems for a wide ran...

In December 2003, seventeen years after the first UK research assessment exercise, Italy started up its first-ever national research evaluation, with the aim to evaluate, using the peer review method, the excellence of the national research production. The evaluation involved 20 disciplinary areas, 102 research structures, 18,500 research products and 6,661 peer reviewers (1,465 from abroad); i...

Ameisen: Die heimliche Weltmacht (Ants: Nature's Secret Power) is a nature documentary about ants. Wolfgang Thaler wrote, filmed, and directed the film, which focuses on the work of ant researcher Bert Hölldobler. The 2004 film was produced by Adi Mayer Film for Österreichischer Rundfunk (Austrian Broadcasting), a public service broadcaster headquartered in Vienna, Austria. Ants: Nature's Secre...

A SIMPLE method for the estimation of carbon dioxide in air or gas mixtures containing anaesthetic gases finds many applications in the investigation of anaesthetic problems and in the control of artificial respiration by mechanical respirators. This adaptation of already established techniques utilizes apparatus which may be found in most hospitals. It is rapid, and can be performed at the bed...

Background Over the past 15 years, strategies for managing dental caries increasingly have emphasized the concept of risk assessment. However, a practical tool for assessing caries risk in infants, children, and adolescents has been lacking. While assessment of caries risk undoubtedly will benefit from emerging science and technologies, the AAPD believes that sufficient evidence exists to suppo...

This study aims to analyze self-confidence using the PBL model assisted by manipulatif materials. Sample in this were students of class VIII SMPK Maria Goretti Ende 2019/2020 school year totaling 30 people. research uses survey and correlational methods. The instrument was a non-test instrument, namely questionnaire composed 20 items based on indicators self-confidence, namely: 1) 2) assertiven...
