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

THE ROLE OF TEMPERATURE AND ADAPTIVE PHENOTYPIC PLASTICITY IN THE EVOLUTION OF DROSOPHILA MELANOGASTER MORPHOLOGICAL CLINES

Variation in morphology results in variation in ecologically relevant performances, which ultimately results in variation in fitness allowing for adaptive evolution. Task performances, such as flight ability, result from the proper scaling of and functional integration of numerous component traits. Morphological variation underlying ecologically relevant task performances can experience strong environmental effects in their expression, or phenotypic plasticity. Historically, the role phenotypic plasticity in adaptive evolution has been controversial, although it has garnered increased support in recent decades. Drosophila spp. are globally distributed and exhibit convergent morphological clines in flight morphology, and importantly, they also exhibit patterns of phenotypic plasticity consistent with these geographic patterns. In the work presented here, I examine if existing patterns of D. melanogaster flight morphology are adaptive regarding flight performance and fitness under the prediction of phenotype-environment matching, wherein the phenotype expressed in an environment enhances fitness in the predicted environment. In the work presented here, I demonstrate (i) phenotypic plasticity in D. melanogaster exhibits a pattern of adaptive phenotype-environment matching in which an induced phenotype is best-suited for flight at the temperature of development, (ii) the pattern of thermally-induced phenotypic plasticity facilitates the evolution of upwind flight performance at Cool and Warm flight temperatures, (iii) adaptive evolution by genetic accommodation is a dynamic process and the contribution of traits responding to selection vary and change over time, and finally, (iv) the adaptive pattern of phenotype-environment matching regarding flight performance is only partially realized as an increase to fitness, measured as survival in presence of predators. My dissertation work importantly demonstrates existing patterns of phenotype-environment matching in D. melanogaster, and demonstrates how this pattern facilitates adaptive evolution by genetic accommodation in a complex phenotype that exhibits natural, continuous variation.Biology and Biochemistry, Department o
