Authors: Widyastuti Sri 
Published: September 2023

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian ekstrak buah Rambusa (Passiflora foetida L) terhadap peningkatan kadar hemoglobin pada mencit (Mus musculus) dan menentukan pada konsentrasi berapa yang paling efektif. Penelitian ini menggunakan 15 ekor hewan uji mencit yang dibagi atas 5 kelompok yang diukur kadar hemoglobin awalnya sebelum diberikan natrium nitrit sebagai penginduksi selama 14 hari, kemudian diukur kadar hemoglobin pada hari ke 15, kemudian diberikan perlakuan, kelompok I (kontrol negatif) diberi Na-CMC, kelompok II, III, dan IV, masing-masing diberikan ekstrak buah Rambusa konsentrasi 0,75% b/v, 1,5% b/v dan 2,25% b/v, sebagai kelompok perlakuan dan untuk kelompok V (kontrol positif) diberikan sangobion 0,15% b/v sebagai pembanding, diukur kadar hemoglobin setelah perlakuan pada hari ke- 15, 16 dan 17. Hasil penelitian menunjukkan bahwa pemberian ekstrak buah Rambusa berpengaruh terhadap peningkatan kadar hemoglobin pada mencit jantan. Berdasarkan analisis Varians menunjukkan adanya perbedaan yang bermakna antar perlakuan (P 0.000 < 0.05). Ekstrak buah Rambusa konsentrasi 2,25% b/v menunjukkan penagaruh paling efektif terhadap peningkatan kadar hemoglobin, tetapi efeknya masih lebih rendah dibandingkan pemberian suspensi Sangobion 0,15% b/v sebagai kontrol positif.

Synthesis and Properties of Hypercoordinate Stannanes and Polystannanes
Authors: D’Amaral Gloria 
Published: September 2023

<p>Asymmetric tetraorganotin (IV) compounds containing either a flexible propyl alcohol ligand (<strong>10</strong>) or a semi-flexible ethyl 2-pyridyl ligand <strong>(11</strong>) were synthesized in good yields via select hydrostannylation reactions. The triphenyl derivatives were converted in good yields to their dihalide stannane intermediates (<strong>6</strong>, <strong>7</strong>), respectively, by mild sequential chlorination with HCl or by reaction with Br<sub>2</sub>. The dihalides were converted to reactive dihydride monomers (<strong>8</strong>, <strong>9</strong>) by a reaction with LiAlH<sub>4</sub> or NaBH<sub>4</sub> in good yields. All stannane intermediates and monomers were fully characterized by NMR (<sup>1</sup>H, <sup>13</sup>C, <sup>119</sup>Sn) spectroscopy and high-resolution mass spectrometry. DFT calculations were also performed on the ethyl 2-pyridyl stannane intermediates <strong>2 </strong>and <strong>7, </strong>which revealed optimized structure geometry and electronic energies. From the three methods that were used, M05-2X-GD3 showed the lowest mean sum of squared distances (MSSD) value and the lowest electronic energies of the hypercoordinate structures. Polymerization of the corresponding dihydrides in the presence of both early and late transition metal catalysts produced moderate molecular weight polymers <strong>10a </strong>and <strong>11a</strong>. Compound <strong>10a </strong>was cast onto a transparent film for the first time and was additionally coated on a PET film. While the cast film on PET showed good flexibility, an initial evaluation of its electronic properties using a 4-probe conductivity device revealed no intrinsic semi-conductivity. Optimization of the polymerization of <strong>10a </strong>involved a catalyst screening, using alternative dehydrocoupling catalysts. A new ethyl 2- pyridyl containing polystannane <strong>11a </strong>was synthesized with a Mw of 11,200 Da using RhCl(PPh<sub>3</sub>)<sub>3</sub>, and <sup>119</sup>Sn NMR revealed the presence of both 4- and 5-coordinate Sn centers randomly distributed along the backbone. </p>
Using a GIS Approach to Evaluate Spatial Accessibility to Neighbourhood Amenities and Natural Environmental Features: Implications for Older Adult Health in the Toronto CMA
Authors: Wehr Alexandra 
Published: September 2023

<p>Older adults (i.e., adults aged 65+) have become the fastest-growing age group in Canada. This demographic shift has resulted in accelerated demand for health-promoting resources as older adults age in place. This project analyzes potential spatial accessibility of health-promoting neighbourhood amenities (NAs) and natural environmental features (NEFs) among Census tracts and Census subdivisions in the Toronto Census Metropolitan Area. Spatial accessibility of these resources is analyzed for older adults residing in different neighbourhoods and communities. Geographic information systems are used to implement methods including the enhanced two-step floating catchment area accessibility model, location quotient, and bivariate local indicators of spatial association. Two travel scenarios (i.e., walking and driving) represent common modes of transportation. Results indicate significant variation in spatial accessibility between NAs and NEFs and spatial mismatch between older adult concentration and spatial accessibility. This project provides a modest basis for improvement of service provision, supportive infrastructure, and health promotion. </p>
An Investigation of Social Media Use for Environmental Norm Development: An Exploration of an Emerging Multi-Actor Regulatory Governance Normative Process
Authors: Martin Madeleine 
Published: September 2023

<p>This dissertation posits that social media platforms (e.g., Twitter and Facebook) represent a new process and fora for the development and implementation of norms that regulate environmental behaviour, with unique characteristics, strengths, and weaknesses, when compared with conventional processes and fora for regulatory activity and codified norm development, such as state-based legislative assemblies and non-state standards bodies. Distinctive features of social media platforms affect user interactions and experiences, which in turn impact how environmental norm conversations take place on those platforms, as opposed to norm conversations that take place through legislatures or formal standards processes. In addition, distinctive characteristics of public sector, private sector, and civil society actors affect how they use social media in development of environmental norms. This research hypothesizes that the way in which social media is used to formulate environmental norms and the importance of social media as a venue for environmental norm conversations varies, depending in large part on distinctive characteristics of the governance actors (i.e., government, third sector actors, and the private sector) and their societal roles, interacting with the distinctive characteristics of social media. In addition to a cross-disciplinary review of scholarly literature, this dissertation explores the veracity of this hypothesis using two investigations; one that compares the use of Twitter by two Ontario government agencies, and a second case study that explores of a Twitter micronorm conversation about the groundwater operations of the water bottling industry in Ontario and other jurisdictions. </p>
Landscape and Hydrologic Patterns' Impact on Microbial Activity: A Comparison of Arctic Watersheds
Authors: Bushnell Ross 
Published: September 2023

<p>Water security is a significant issue facing communities of the Canadian Arctic and is a fundamental component to the health, economic development, and ecological integrity of northern communities. Local water sources are under pressure from environmental changes and anthropogenic influences and need to be understood in order to protect them. The aim of this study was to collect landscape, hydrologic, and microbial baseline data in the communities of Baker Lake, Nunavut and Pond Inlet, Nunavut watersheds in order to, (1) characterize each of the study watersheds, (2) explore the relationships between precipitation, vegetation distributions, water chemistry, and microbiological indicator total coliforms (TC), (3) guide future research and source water management, (4) create capacity for northern communities to conduct watershed research. These research goals were guided by the residents of the study communities and volunteers collaborated to achieve this research in all part of the research process. Measurements were taken at two watersheds in Baker Lake, Nunavut during the summer of 2019 and six watersheds in Pond Inlet, Nunavut in the summers of 2017 and 2018. Watersheds that had higher proportions of <em>Wet </em>vegetation generally had higher TC measurements during the sampling season. In addition, the results showed that major precipitation correlated with higher TC measurements, though a 3-5 day lag between the precipitation event and the TC increase was found. The lag time between the spike in TC and the rain event varied temporally and spatially. The results suggest that watershed vegetation composition, slope, and hydrologic patterns influence the lag time between the “flushing” of the landscape and the response of microbiological indicators. The results will contribute to baseline knowledge which policy makers and the community can use to establish policies to ensure the health and sustainability of northern water sources. In addition, placing a emphasis on the exchange of knowledge with northern residents will facilitate the capacity for the communities to conduct their own research in the future. This local scale research is vital for northern communities to be able to prepare for the impacts climate change and development is having on their environment. </p>
The Continuation of Native Non-Invasive Plant Species Research of Engineered Wetlands
Authors: Tucci Joanna 
Published: September 2023

<p>Wetlands are vital ecosystems that are capable of polishing wastewater. Although there is extensive research on constructed wetland wastewater treatment, information regarding the use of native non-invasive macrophytes is lacking. The first part of this study examined the use of native non-invasive plant species in laboratory-based engineered wetlands to assess their growth and nutrient removal. The blue flag iris, cardinal flower and sneezeweed were chosen for the experiment as they developed best under the laboratory conditions. Plant biomass increased with phosphorus additions and phosphorus concentrations remained high and were not reduced. The results are preliminary and further research is necessary. </p>
<p>In the second part of this thesis the Palgrave Forest and Wildlife Area was visited to assess species identification, presence and seasonality. A total of 15 plant species were identified at the wetland, where 5 are invasive. As expected, seasonality had an impact on wetland productivity, biomass and species presence. </p>

Peanut (Arachis hypogaea L.) growers use different tillage systems in the Southeastern United States, the impact of which needs to be assessed with regard to evapotranspiration (ET), carbon uptake, and water-use efficiency (WUE). The eddy-covariance method was used to measure these fluxes in peanut in two common tillage systems (strip tillage vs. conventional tillage) over the course of three consecutive growing seasons (2019–2021). Results suggest that during the dry year of 2019 with rainfall of only 30 cm, strip tillage peanut had a significantly higher daytime ecosystem WUE, 105%, 51%, and 32% higher than that of the conventional tillage in early, mid, and late growth stages, respectively. In 2020, with mean rainfall the overall difference in average WUE was nonsignificant between the tillage systems. Heavy rainfall of 112 cm in 2021 led to waterlogged conditions in the conventional tillage field due to poorer infiltration. This likely reduced the CO2 uptake. Waterlogging did not occur in the strip tillage field due to improved infiltration. As a result, in 2021, 18%, 33%, and 48% greater ecosystem WUE in strip tillage during early, mid, and later stages was found. Thus, this study suggests that strip tillage fields can achieve higher net CO2 uptake and WUE in Georgia during dry or very wet years. However, no difference in WUE was found between different tillage systems in a typical year with average rainfall for Georgia. The present study has implications for regions characterized by long growing seasons and low rainfall.
