Historic Past, Promising Future: An Archival Research Project on Tourism and Identity in the Limestone City
Authors: Charete Jasmine 
Published: April 2021

1973: The City of Kingston holds a year-long birthday celebration in honour of its 300th called Tercentenary. Planning for this event takes three years and ongoing consultation with major stakeholders in the city and its residents. This archival research presentation discusses the original motives behind the Tercentenary Committee and its members, the key events in both planning and execution of Tercentenary, and major festivities throughout the year and their impact on the Kingston community and the image of Kingston as a historic city. As with many other heritage tourism events, the City uses Tercentenary to solidify community identity and civic pride in order to further promote tourism and profits from visitors. Benedict Anderson’s Imagined Communities theory informs the project, alongside other Canadian examples of heritage tourism that shaped regional identity over the past century. Using these secondary sources, I will argue that the Committee(s) desire to tie the City’s Historic Past to its Promising Future shaped their perspectives on marketing Tercentenary to residents and Kingston stakeholders as much as to visitors. This project is one of the first in a new course offered in the History Department titled HIST 501: History/Queen’s Archives Internship. Students complete archival tasks such as indexing and minor preservation and can choose to partake in a personal research project.
Portable Tracked Ultrasound System to Monitor Spinal Curvature
Authors: Hess Maggie 
Published: April 2021

ntroduction: Adolescent idiopathic scoliosis (AIS) is the most frequent spinal deformation. It is assessed by frequent x-ray imaging, exposing patients to frequent radiation, increasing the risk of cancer. Tracked ultrasound imaging produce a three-dimensional visual of the spine without risk. We proposed using an optically tracked handheld USB Interson ultrasound probe, which is much less expensive than the current standard ultrasounds.
Methods: A practical setup was developed for scoliosis monitoring. Reference markers were on the patient’s shoulder and the wall to account for patient motion, and simulate the plane of the x-ray detector to allow future comparisons. The optical tracker tracked the markers and ultrasound probe. This was compared to the electromagnetically tracked non-portable Ultrasonix ultrasound. Scanning captured the thoracic and lumbar regions. A three-dimensional image was composited by stacking a series of two-dimensional ultrasound slices in their tracked physical positions. To compare the two-ultrasound setups and ensure the ease of identification, a novice attempted to manually identify transverse processes. These were compared to see if all transverse processes scanned could be marked from both ultrasound setups. Two clinical experts then confirmed the markings were anatomically correct.
Results and Conclusions: In all scans 100% of the transverse processes scanned (n = 51) were identified in Interson and Ultrasonix images. Curvatures measured using the Ultrasonix method have been previously validated to curvature measurements from x-ray images. Thus the 100% correspondence of the Interson and Ultrasonix setups indicates this inexpensive method is a promising tool to reduce radiation exposure during scoliosis monitoring.
Examining the Validity and Utility of Two New Measurement Devices in Sexual Psychophysiology Research
Authors: Shelley Amanda 
Published: April 2021

Background: Female genital arousal is an important, yet difficult phenomenon to measure.
The Laser Doppler Imager (LDI) and the Litmus Test Strip (LTS) are new measurement devices for assessing vulvar blood flow and vaginal lubrication, respectively. Given their recent development, few studies have used these measures, and further testing of their validity is needed. Using both devices concurrently provides an opportunity to demonstrate convergent validity (i.e., a significant, positive correlation) between these measures. Investigation of the utility of these devices—such as their sensitivity to varying intensity of sexual arousal—is also needed. Measures that can detect intensity of genital arousal allow researchers to study more complex questions than measures that only indicate the presence or absence of it.
Method: Sexual arousal will be induced using erotic videos depicting foreplay and penile-vaginal intercourse. Vulvar blood flow and vaginal lubrication will be assessed using the LDI and the LTS. Participants will self-report their experience of sexual arousal.
Hypotheses: I predict that:
1. Changes in vulvar blood flow (as measured by LDI) and vaginal lubrication (as measured by LTS) will be positively correlated with self-reported sexual arousal;
2. Changes in vulvar blood flow and vaginal lubrication will be positively correlated with each other;
3. Vulvar blood flow and vaginal lubrication will vary according to intensity of sexual response.
Results: Data collection in progress. Results will be available at the time of the presentation.
Implications: Further development of two new measurement devices for sexual psychophysiology research.

Authors: Potes Mark Immanuel , Joaquin Christian , Wiecks Nicole , Phan Sheshanna , Hassan Omron 
Published: April 2021

Background:
Deep brain stimulation (DBS) has demonstrated preliminary success as a treatment for neuropsychological disorders including obsessive-compulsive disorder and substance use disorder. This systematic review aims to assess the use of DBS in treating eating disorders (EDs) to determine its utility and the extent of adverse effects.

Methods:
A PubMed search following PRISMA guidelines was executed to find studies encompassing DBS as a treatment of ED. Outcomes were extracted from the literature and summarized while a review of quality was also performed.

Results:
From a search yielding 299 publications, 11 studies published between 2010 and 2020 were found to fit the inclusion criteria. Out of 53 patients who began with an abnormal BMI before treatment, 22 patients (41.5%) achieved normal BMI on follow-up. Significant neuropsychological improvement was seen in most patients as measured by neuropsychiatric testing and questionnaires.

Conclusion:
DBS as a treatment for ED may result in significant objective and psychological benefits. Further studies should aim to increase the sample size, standardize follow-up protocol, and standardize the neuropsychiatric tests used to determine psychological and physiological benefits.
SnO2 -SiO2 1D Core-Shell Nanowires Heterostructures for Selective Hydrogen Sensing
Authors: Raza Muhammad Hamid , Kaur Navpreet , Comini Elisabetta , Pinna Nicola 
Published: April 2021

SnO2 is one of the most employed n-type semiconducting metal oxide (SMOX) in chemo-resistive gas-sensing although it presents serious limitations due to a low selectivity. Herein, we introduce one-dimensional (1D) SnO2-SiO2 core-shell nanowires (CSNWs). SnO2 nanowires (NWs) are synthesized by vapor–liquid–solid deposition and the amorphous SiO2-shell layer with varying thicknesses (1.8-10.5 nm) was grown by atomic layer deposition (ALD). SiO2-coated SnO2 CSNWs show lower baseline conductance as compared to the Pristine SnO2 NWs, due to an enhancement of the electron depletion layer. The SnO2-SiO2/N CSNWs (N representing the number of SiO 2 ALD cycles) sensors show a dramatic improvement of the selectivity towards hydrogen. Moreover, the sensing-response markedly depends on the thickness of the SiO2-shell layer and the working temperature. The SnO2-SiO2/60 CSNWs sensor (ca. 4.8 nm SiO2 shell thickness) was the best performing sensor in terms of selectivity and sensitivity exhibiting a response of 160 (ca. 7-folds higher than the pristine SnO2 NWs) towards 500 ppm of hydrogen at 500 °C with a lower detection limit at ppb-level (0.082 ppm). The selectivity and enhanced sensing-response are related to the masking effect of the SiO2 shell and an increased in the width of the electron depletion layer due to the strong electronic coupling between the SnO2 core and SiO2-shell layer, respectively. The remarkable sensing performances of the SnO2-SiO2/N CSNWs can be attributed to the homogeneous and conformal SiO2 shell layer by ALD,electronic coupling between the core and the shell, the optimized shell thickness and high surface area provided by the 1D SnO2 NWs network.

Knowing particularities of soils allows the adoption of sustainable management practices. The most efficient method to obtain data on the soil is through its characterization, essential for planning land use and soil conservation. However, soil surveys conducted in the conventional methods are costly and time-consuming. This study aimed to identify spectral patterns in the mid-IR wavelengths for a quick and low cost characterization of soil classes. Soils from the Natuba river basin, Pernambuco State, Brazil, were used. These soils were mapped on a scale of 1:25,000, where the presence of Latossolos, Argissolos, Gleissolos and Neossolos were identified. The data of reflectance for profiles of each soil class were collected using the spectral range between 2,500 and 25,000 nm. In the mid-IR region, Latossolos and Argissolos presented spectral characteristics peculiar to classification criteria. The increased contents of organic matter and iron oxides reduced soil reflectance. The horizons with sand content above 80% showed strong absorption spectra and significant reflectance peaks of quartz in the mid-IR. The wavelengths 2,681, 2,600 and 2,495 cm-1 occurred only in these horizons. The spectral analysis presented as a high-potential method for the characterization and classification of soils.Keywords: spectral patterns, reflectance, soil absorption features, organic matter, iron oxide

Authors: Tahiri F. E. , Chikh K. , Khafallah M. 
Published: April 2021

This paper proposes optimal control strategies of a standalone Hybrid Power System (HPS) to supply sustainable and optimal energy to an isolated site with improved quality of electrical energy. A topology of Isolated Hybrid Power System (IHPS) is proposed, consists of: a Photovoltaic System (PVS), a Wind Energy Conversion System (WECS), electronic power devices controlled to maximize energy production from renewable sources and to maintain the constant DC-link voltage, a Battery Energy Storage System (BESS), Diesel Generator (DG), and a Pulse Width Modulation (PWM) Voltage Source Inverter (VSI) located at the load-side end. In addition, a novel control strategy has been proposed, in this work, to maximize the power from the PVS. This presented strategy, based on the combination between Perturb and Observe (P&O) algorithm and the Fuzzy PI Controller (FPIC), presents a good performance, especially in the dynamic state compared to the classical algorithm P&O. A supervisory control algorithm has been elaborated to manage the energy flows between the devices of the hybrid system to make the decision of the optimal operating mode in order to ensure a continuous supply of the load with minimum usage of batteries and DG. The simulation results developed in the Matlab/Simulink environment are applied to show the efficiency and performance of the proposed control strategies in terms of power optimization and energy management.

Authors: Ladakis I. , Chouvarda I. 
Published: April 2021

Objectives: Stress is a normal reaction of the human organism induced in situations that demand a level of activation. This reaction has both positive and negative impact on the life of each individual. Thus, the problem of stress management is vital for the maintenance of a person’s psychological balance. This paper aims at the brief presentation of stress definition and various factors that can lead to augmented stress levels. Moreover, a brief synopsis of biosignals that are used for the detection and categorization of stress and their analysis is presented. Methods: Several studies, articles and reviews were included after literature research. The main questions of the research were: the most important and widely used physiological signals for stress detection/assessment, the analysis methods for their manipulation and the implementation of signal analysis for stress detection/assessment in various developed systems. Findings: The main conclusion is that current researching approaches lead to more sophisticated methods of analysis and more accurate systems of stress detection and assessment. However, the lack of a concrete framework towards stress detection and assessment remains a great challenge for the research community. Doi: 10.28991/esj-2021-01267 Full Text: PDF

Published: April 2021

Устранение поверхностных трещиноподобных дефектов типа «риска» на участках подводных переходов магистральных трубопроводов возможно методом вышлифовки на глубину до 20 % толщины трубы. Ранее было подтверждено, что в подводных условиях все основные методы неразрушающего контроля позволяют стабильно выявлять имеющиеся в зоне вышлифовки произвольно ориентированные поверхностные дефекты протяженностью от 20 мм и глубиной от 1,5 мм. Однако при меньших геометрических параметрах дефектов имеется вероятность их неполного устранения либо необнаружения. Для оценки возможности эксплуатации трубопровода с поверхностным дефектом с учетом принятых режимов диагностики проведены циклические испытания по критериям механики разрушений полноразмерных образцов с нанесенными в зоне вышлифовки поверхностными трещиноподобными концентраторами напряжений указанных размеров. Все группы образцов показали более чем двукратное превышение длительности инкубационного периода развития трещины по сравнению с количеством циклов нагружения, которое может испытать трубопровод за средний межинспекционный период эксплуатации. По результатам испытаний подтверждена возможность проведения ремонта поверхностных трещиноподобных дефектов типа «риска» на подводных переходах магистральных трубопроводов с различным сроком эксплуатации методом вышлифовки без установки кессона на ремонтируемый участок.
Elimination of surface crack-like defects of the “risk” type on underwater crossing sections of trunk pipelines is possible by grinding to a depth of up to 20 % of pipe thickness. Previously, it was confirmed that in underwater conditions, all main non-destructive testing methods make it possible to stably identify randomly oriented surface defects in the grinding zone with a length of 20 mm and a depth of 1.5 mm. However, with smaller geometric parameters of defects, there is a possibility of their incomplete elimination or non-detection. To assess the possibility of operating a pipeline with surface defect, taking into account the accepted diagnostic modes, cyclic tests were carried out according to the fracture mechanics criteria of full-size specimens with surface crack-like stress concentrators of the indicated sizes applied in the grinding zone. All groups of samples showed more than a twofold excess of the duration of crack development incubation period in comparison with the number of loading cycles that the pipeline can experience during the average inter-inspection period of operation. Based on the test results, the possibility of repairing surface crack-like defects of the “risk” type at trunk pipeline underwater crossings with different service life by grinding without installing a caisson on the repaired section was confirmed.
