Behavioral Traps in Flight Crew-Related 14 CFR Part 121 Airline Accidents
<p>This dissertation examined pilot behavioral traps in the multi-crew Part 121 air carrier environment. Behavioral traps are accident-inducing operational pitfalls aviators may encounter as a result of poor decision making. The traps studied were: Loss of Situational Awareness; Neglect of Flight …

Modelling and simulation of combustion of dilute syngas fuels in a CFR engine
… syngas fuel in a Cooperative Fuel Research (CFR) spark ignited engine. The laminar flame speeds of the unique fuel mixtures calculated using CHEMKIN were coupled with the geometric features of the CFR engine to create a combustion model of the CFR engine in GT-POWER. Using two-zone modelling …

Flame propagation model for the CFR engine under knocking and non-knocking conditions
… was used to investigate the combustion in the CFR engine (the engine used to measure fuel octane number) since it was found previously that the pressure development, and by implication combustion, differs from that found in production engines.

A multi-zone model of the CFR engine : investigating cascading autoignition and octane rating
The CFR engine is the standardised research engine used for the measurement of knock resistance of fuels through the Research Octane Number (RON) and Motor Octane Number(MON) tests. In standard production engines, knock manifests as an almost instantaneous pressure rise followed by knock ringing" …

Phylogeographic structure in the CFR genus Pauridia revealed by inter-simple sequence repeat amplification
… P. minuta occupying a wide range across lowland CFR and P. longituba being restricted to granite outcrops on the West coast. Genetic structure correlated to geography has been described for the haploid chloroplast genome. Here the diploid nuclear genome is investigated using inter-simple sequence …

Immunhistochemische Analyse der Expression des CFR-1/PAM-1-Rezeptors auf Karzinomen und deren Präkanzerosen
… post-transkriptionell modifizierte Variante des CFR-1 Rezeptors. Dieser Rezeptor ist auf fast allen Karzinomen unabhängig von Lokalisation und Art exprimiert, aber nicht auf gesundem Gewebe. CFR-1/ PAM-1 ist auch auf Präkanzerosen nachgewiesen worden: Helicobacter pylori-assoziierte Gastritis, …

Employability of the Graduates From 14 CFR PART 147 Schools: Understanding the Critical Factors Using Covariance-Based SEM
… in the United States. To fulfill this need, 14 CFR Part 147 aviation mechanic schools educate students under the supervision of the FAA. Though the demand for mechanics is projected to increase over the next 20 years, the supply is not expected to meet this demand. Therefore, the research …

Absolute values only show part of the whole : evidence of P limitation in legumes in the CFR from N:P ratios
… on nutrient poor and nutrient rich sites in the CFR in the western Cape of South Africa. 6 species of legume and 11 species of non-legume, along with their corresponding soils were taken for macro and micronutrient analysis. Results indicate that legume soils were more nutrient rich than …

Friction and lubrication behaviour of metal-on-metal and ZTA ceramic-on-CFR PEEK hip prostheses. Friction and lubrication behaviour of metal-on-metal hip resurfacing and ZTA ceramic heads versus CFR PEEK cups wiith various diameters and clearances using serum-based lubricants with various viscosities.
… carbon-fibre-reinforced poly-ether-ether ketone (CFR PEEK) cups with different diameters (>35-60 mm) and diametral clearances (60-1860 µm). Seven serum-based lubricants with different viscosities were used with and without carboxy methyl cellulose (CMC) additions as gelling agent to increase …

A Comparative Analysis of Scenario Based Training and Maneuver Based Training in a 14 CFR part 141 Private Pilot Certification Course
… taught using MBT the other SBT – in the Title 14 CFR Part 141 Private Pilot Certification Course on the campus of the University of North Dakota. The mean performance of the two groups was compared in the following areas by using an independent group t test: flight, ground and simulator training …

Phosphorous requirement of indigenous N-fixing legumes and rhizobial diversity in the low P soils of the Cape floristic region, South Africa
Soils of the Cape Floristic Region (CFR) vary in phosphorous (P) availability and legume species tend to be distributed in specific edaphic habitats. Eighteen indigenous CFR legume species were grouped as high-P, low-P, Pgeneralist and unclassified plants, by associating their distribution with …
