Epistemic Responsibility in Echo Chambers
… our attention. One pressing issue concerns echo chambers, which, while not unique to the online episteme, are proliferated in pervasive ways online. Specifically, echo chambers manipulate trust dynamics in such a way that makes finding people epistemically responsible difficult, as contrary …

Ultraviolet laser calibration of drift chambers
… laser as a track calibration source in drift chambers, and specifically in a small time projection chamber (TPC). Drift chambers such as TPCs reconstruct the trajectories of charged particles by amplifying and collecting electrons produced by ionization of gas atoms with which the target …

Diagnostics for ionized physical vapor deposition chambers
As the critical dimension of the semiconductor device continues to shrink and aspect ratio continues to rise, more diagnostics are needed to accurately predict the deposition profile of features on the wafer. Traditionally, the incident ion fluxes are considered to be perfectly normal to the wafer …

Political Echo Chambers: The Internet Facilitates Identity Confirmation
… with different worldviews inhabit identity echo chambers with like-minded others and are empowered to clash with those who have different worldviews. The research conducted in this study aimed to determine whether the easy access to confirming information provided by the Internet satisfies the …

Joe Chambers: musical style and concept, 1964 — 1973
… of percussionist, composer and educator Joe Chambers. The analysis of his musical style and concept will focus on the period between his 1964 recording debut with Freddie Hubbard and his first album as a bandleader in 1973. This period represents a seminal chapter in Chambers’ lengthy career, …

Dielectric liquid ionization chambers for detecting fast neutrons
Three ionization chambers with different geometries have been constructed and filled with dielectric liquids for detection of fast neutrons. The three dielectric liquids studied were Tetramethylsilane (TMS), Tetramethylpentane (TMP), and Isooctane, which each have intrinsic properties that make …

Regional Mechanical Properties and Microstructure of Ovine Heart Chambers
… of the normal heart tissue. Although heart chambers have the same embryonic origin, differences in the development of mechanical properties are expected to manifest over time during the adulthood period. Therefore, the goal of this study was to determine the passive mechanical properties of …

Crystal mobilisation in convecting magma chambers: an analogue experimental approach
… igneous intrusions from originally liquid magma chambers display a large number of different sedimentary features. These features include the gravitational collapse of sidewalls producing slumps and the layering produced by gravitational settling of crystals. In the chamber fluid-dynamic …

Increased production of aligned cellulose nanofibrils using microfluidic mixture chambers
… using flow focusing in microfluidic mixture chambers is examined and tested. This process accomplishes the difficult task of aligning cellulose nanofibrils and gelling them together to create macroscale cellulose fibers, and this study seeks to test the limit of macroscale cellulose fiber …

Computational analysis of thermo-acoustic instabilities in combustion chambers and afterburners
… instabilities in asymmetric combustion chambers. Such instabilities can be triggered when correlations between heat-release and pressure oscillations exist, leading to undesirable effects. Gas turbine designs typically consist of a periodic assembly of N identical units; as evidenced by …
