Creating a Linked Data-Friendly Metadata Application Profile for Archival Description

We provide an overview of efforts to apply and extend Schema.org for archives and archival description. The authors see the application of Schema.org and extensions as a low barrier means to publish easily consumable linked data about archival resources, institutions that hold them, and contextual entities such as people and organizations responsible for their creation.Comment: 11 pages, 3 figures; full poster available from http://dcevents.dublincore.org/IntConf/dc-2017/paper/view/50

Development of Digital Techniques for Analysis of Hormone Regulation of Melanophore Activity in Red Drum

Melanophores are pigment bearing cells, which have been used as a practical method to demonstrate mechanisms of hormone interaction. A current teaching laboratory has been restructured in order to increase student participation, provide tangible results, and reduce subjectivity in procedures to more accurately analyze hormone interaction. To accomplish this, digital cameras were used to photograph scales of red drum (Sciaenops ocellatus), which were then analyzed using ImageJ software to determine melanosome area. From collected data, a region posterior to the pelvic fin and dorsal to the lateral line on the red drum was determined to yield stable basal melanophores to provide a standard starting state for student experiments. By measuring the area of basal melanophores, one can compare dispersed melanophore area after hormone treatment (α-MSH and norepinephrine) to quantify a hormone’s effect. Hormone interaction can be illustrated by subjecting scales to different hormones in series. Other chemicals such as IBMX and a K+ rich medium were also used to demonstrate melanophore regulation. Experiments showed that basal state of melanophores could not be manipulated by changing illumination of environment or by removing scales from red drum at different times of day. Physiological doses of hormones to be used in the laboratory were determined by testing various doses’ effect on melanophore activity over time. Once physiological doses were established, a sequence of serial chemical treatments was developed to best demonstrate melanophore activity by examining dispersing and aggregating effects in the presence of other chemicals. This method of melanophore analysis has proven useful as a teaching tool, but may also be used to analyze novel treatments on melanophore activity

Modeling Shape Memory Polymer fill Honeycomb as a Composite Skin for a Morphing Wing

Due to its complex phase transformation behavior, a Shape Memory Polymer filled honeycomb composite has been proposed as an efficient material for skin on a morphing wing. This work develops a finite element model of the honeycomb composite that captures the material behavior while morphing through all geometric phases. To model the shape memory polymer filling, the simulation implements an experimentally calibrated user defined material subroutine in Abaqus, a commercially available finite element software. In order to validate the model, the modeled behavior is compared to experimentally determined behavior of shape memory polymers. The geometry and deformations of representative unit cells are then discussed

Altitude Acceleration Investigation of the RA-14 Avon Turbojet Engine

As a part of this investigation, the acceleration characteristics of the engine, using the standard engine fuel-control system, were obtained for conditions simulating flight at altitudes of 35,000 and 50,000 feet with a flight Mach number of 0.4. Rapid and wave-off type accelerations were made at each flight condition, and the transient performance of the engine was recorded with a multiple-channel oscillograph. The parameters are presented graphically in the form of time histories, augmented by short segments of the oscillograph recordings, in order to more completely describe the behavior of the engine parameters when surge was encountered

Junior high school students\u27 perception of the messages conveyed through the lyrics of rock music

The purpose of this study was to discover whether or not the accompaniment of a lyric sheet while listening to rock music would aid a student\u27s correct identification of the message conveyed by that song. Participants included one 7th and one 8th grade class of gifted students (N = 62). Other elements examined involved students\u27 judgment of the messages as negative or positive, as well as the tonality of each song as pleasant or unpleasant and how these judgments related to correct or incorrect identification of the messages. Results indicated that there was no statistically significant difference regarding correct or incorrect identification of the message depending on whether or not students did or did not have a lyric sheet to read while listening to the U2 song, while there was a statistically significant difference concerning the Black Sabbath song. Additional results of this study are discussed, and implications for future research are suggested
