The aviation industry is set to see another significant leap in new technology, namely electric aircraft. As of the time of this research, both 9-seat and 19-seat aircraft would be ready to be launched by air service providers under the Essential Air Service (EAS) program. While electric aircraft manufacturers are...

Microbiome 10, 206 (2022). https://doi.org/10.1186/s40168-022-01412-x and Background: Effective surveillance of microbial communities in the healthcare environment is increasingly important in infection prevention. Metagenomics-based techniques are promising due to their untargeted nature but are currently challenged by several limitations: (1) they are not powerful enough to extract valid signals out of the background noise for low-biomass samples,...
Building Information Modeling (BIM) and Virtual reality (VR) have attracted growing attention within the architecture, engineering, and construction (AEC) industry in recent years. Integration of BIM and VR technology can develop workflow efficiency through enhanced common understanding and prepare students in architecture and engineering programs to become leaders of the...
Within the world of art music, composers have employed a variety of techniques to infuse popular music elements into their writing. This document is an examination of specific instances of this trend in twenty-first century wind ensemble repertoire. The study is limited to twenty-first century wind ensemble works by living...
In 1936 Modibo Keita, a twenty-year-old student at the distinguished Ecole William Ponty in Gorée, Senegal, wrote his “mémoire de fin d'étude” on Soninke childhood. The original manuscript is held in the archives of French West Africa in Dakar, part of the collection of “cahiers de William Ponty.” This paper... and En 1936 Modibo Keita, un étudiant de vingt ans à l'école distingué William Ponty à Gorée, au Sénégal, a écrit son mémoire de fin d'étude sur l’enfance sarakollé. Le manuscrit original se trouve dans les archives de l'Afrique occidentale française à Dakar, où il fait partie de la collection de...
This paper describes proposed schemes for describing and indexing two image collections and requirements for the software that would give the end-user access to thesaurus terms and a graphical display of the faceted classification structures of indexing records. Editorial cartoons comprise one collection, dance videos the other.
The gradual evolution of the material properties of a cement-based material, i.e. the stiffness of cement paste, is the result of the continuous change of the microstructure with the progress of the hydration process. Based on an existing micromechanical model for the simulation of the shear and elastic modulus of...
In this paper, the correlation of reflection loss measured by an ultrasonic shear wave reflection
method and the microstructure in cement-based material is investigated. Three cement pastes
(Portland cement type I) with different water-cement ratios (0.35, 0.50 and 0.60) cured at 25
°C were examined. The ultrasonic shear wave reflection...
The paper deals with the behavior of fluid cement pastes, formulated from Self Consolidating Concretes (SCCs), and the experimental correlation of fundamental rheological properties, such as the yield stress and the viscosity, with measurements from field tests, such as the mini-cone slump flow test. As a matter of fact, several...
Gentrification - the process in which higher income (and often younger) households displace lower income residents of a city neighborhood - has been occurring in many urban neighborhoods over the last few decades. This process changes the demographics, and often the essential character, of the neighborhood. As a result, we...
