In Light of the Lamps: A Comprehensive Analysis of the Ceramic Oil Lamps from the Roman Fort at Humayma
Authors: Hickox Lilly 
Published: April 2021

The archaeological site of Humayma, located at the northwest corner of the Hisma desert of Jordan, has a long history of permanent settlement; beginning with the Nabataeans, followed by Roman, Byzantine, and Islamic occupations. Shortly after Emperor Trajan’s conquest of the Nabataean Kingdom in 106 CE, a Roman fort emerged alongside the pre-existing trade route, which the Romans renamed the Via Nova Traiana. Excavations at the fort, directed by J. P. Oleson in 1995, 1996, 2000, 2004, and 2005 and M. B. Reeves in 2012, unearthed a collection of ceramic oil lamps, comprised of four complete lamps and fifty-eight fragments. The author recently carried out a complete evaluation of the fort’s ceramic lamp collection, remotely analysing the lamps based on project images, descriptions, and contextual information in order to produce a catalogue and report.
Results included Nabataean, Roman, and Byzantine types, dating from the 1st to 5th century CE, revealing an intricate and diverse account of material culture at the fort. The Nabatean rosette lamp and Byzantine slipper lamp were the two most prevalent types, while few Roman lamps were found. The author interpreted data and made suggestions in light of the history, regional trade, stratigraphic complexities, and evolving cultural identity of the site. This poster summarizes the ceramic lamp findings, identifies anomalous items, and considers the significance of chronological aberrations in relation to the fort’s military and civilian occupations over 400 years.
Selection for two different mating systems in Aquilegia canadensis
Authors: Dean-Moore Chloë 
Published: April 2021

Because plants are sessile, they depend on biotic and/or abiotic vectors to transfer pollen from the male pollen-producing anthers to the female pollen-receiving stigmas. As a result, plant mating systems evolve through selection on the floral traits that influence how much pollen is transferred from anthers to stigmas within flowers (self-pollination) vs. between flowers on different individuals (outcrossing). Thus, mating systems are influenced by the traits that dictate the relative abundance of self-versus outcrossed pollen on stigmas. Spatial separation between anthers and stigmas within flowers (herkogamy) is expected to regulate self-pollination yet there are few estimates of how natural selectin acts on this trait. Aquilegia canadensis (columbine, Ranunculaceae) is a short-lived herbaceous plant of rocky outcrops throughout eastern North America that makes seed through both self-fertilization which is influenced by herkogamy, and outcrossing, which is likely influenced by the plant’s floral display size (flower number and size). Selfing provides reproductive assurance in natural populations of columbine, whereas outcrossing appears to produce much fitter offspring, and there is a trade-off between thes two components of the mating system. We, therefore, predicted correlational selection between herkogamy and display size: selection would favour reduced herkogamy among individuals with small floral displays (to enhance reproductive assurance) and increased herkogamy among individuals with large floral displays (to reduce selfing when outcrossing is likely). We tested this prediction by using multivariate linear regression to estimate phenotypic selection through seeds/fruit and seeds/plant on floral traits and plant size for 1015 plants from nine populations of A. canadensis at the Queen’s University Biological Station. Although we detected positive direction selection on display size mostly through flower number, we did not detect selection on herkogamy or correlational selection between herkogamy and display size. As expected, large size is universally favoured yet selection of floral morphology is weak.

The ISO 5832-1 austenitic stainless steel used as biomaterial is largely applied in the area of orthopedics, especially in the manufacture of implants, such as temporary or permanent replacement of bone structures. The objective of this study was to evaluate the localized corrosion resistance of the ISO 5832-1 stainless steel used in orthopedic implants by electrochemical tests in two different solutions. The results of this study are of great interest to evaluate the corrosion of metallic implants that can result in the release of corrosion products into bodily fluids causing possible adverse biological reactions. The determination of the chemical elements in the composition of the ISO 5832-1 stainless steel was performed by neutron activation analysis (NAA). The samples for electrochemical tests were grinded with silicon carbide paper up to #4000 finishing, followed by mechanical polishing with diamond paste. The open circuit potential measurements and anodic polarization curves were obtained in solution of 0.90 wt. % of NaCl and of simulated body fluid (SBF). The results indicated that the ISO 5832-1 stainless steel presented a high resistance to crevice corrosion in simulated body fluid solution but high susceptibility to this form of corrosion in the chloride solution.
