Visible Light-Assisted Degradation Of Malachite Green Dye Using Waste Tea-Mediated Zinc Nanoparticles, Rehana Baiju Mampilly, Amanullakhan Pathan, C. P. Bhasin

International Journal of Thin Film Science and Technology

This work presents entirely a new, green, and non-expensive route of synthesis of zinc nanoparticles (NPs) using waste tea. The crystalline nature of waste tea-mediated Zn NPs (WT-ZnO NPs) was confirmed by XRD and SAED analyses. Further characterizations of WT-ZnO NPs were done using UV-vis spectroscopy, FTIR spectroscopy, SEM- EDX, and TEM. The size of synthesized NPs was calculated to be 15.1 nm which presented spherical morphology with some sorts of agglomeration. The WT-ZnO NPs when applied as visible light-driven photo catalyst for degradation of Malachite green dye. Adsorptions of Malachite green (MG) dye follow pseudo-first-order kinetics. It was found …

Ecological Complexity And Avoiding Pest Resurgence: Intuitions From Mathematical Ecology, Theresa Ong, John H. Vandermeer

Dartmouth Scholarship

Pest resurgence is defined by a predictable increase in pests following declines resulting from the implementation of pest management practices. This phenomenon is notorious; familiar in biblical references to cyclical plagues of locust and discussions of pesticide treadmills, where pests resurge following the evolution of pesticide resistance. Targeted “silver-bullet” approaches, whether chemical, mechanical, biological, or genetic in nature, apply a reductionist lens toward the removal of a specific target pest, often ignoring ecological context, by application of said silver-bullet. In this review article, we cover how past and recent developments in theoretical ecology and complex systems dynamics provide a general …

The Future Of Health Care Work And The Place Of Migrant Workers Within It: Internationally Educated Nurses In Ontario Canada During The Covid-19 Pandemic, Margaret Walton-Roberts

Global Nurse Migration Pathways: A Comparative Project

The COVID-19 pandemic highlighted the importance of immigrant health workers in OECD nations, and intensified debates about the current and future supply and distribution of such workers, particularly nurses. This review paper considers internationally educated nurses in the case of Ontario, Canada, and the policy responses developed during the pandemic to address the increased utilization of immigrant health workers. To further consider the evolving place of migrant workers within health, the broader issue of the future of health care work is examined to imagine what a sustainable and resilient health workforce agenda that integrates internationally educated nurses might look like.

Beyond All Drought: Improving Urban Water Conservation In The West Through Integrative Water And Land Use Policy, Benjamin Longbottom, Alexandria Gordon

Natural Resources Journal

Although droughts have long plagued the western United States, rapid population growth and climate change are making the American West increasingly water insecure. In some western states, including Arizona, Colorado, and California, decisionmakers are responding to these changes with innovative water conservation-focused land use policies. In other states, however, water and land use policies are lagging decades behind. Improving water security in western cities is an enormous task, requiring extensive social, legal, and policy reform. Additional federal funding for western water security initiatives could do much to drive that reform, but state and local governments should also play a leading …

Panta Rhei Benchmark Dataset: Socio-Hydrological Data Of Paired Events Of Floods And Droughts, Heidi Kreibich, Elliot Wickham, Et Al.

School of Natural Resources: Faculty Publications

As the adverse impacts of hydrological extremes increase in many regions of the world, a better understanding of the drivers of changes in risk and impacts is essential for effective flood and drought risk management and climate adaptation. However, there is currently a lack of comprehensive, empirical data about the processes, interactions, and feedbacks in complex human–water systems leading to flood and drought impacts. Here we present a benchmark dataset containing socio-hydrological data of paired events, i.e. two floods or two droughts that occurred in the same area. The 45 paired events occurred in 42 different study areas and cover …

The Most Environmentally Sustainable Diet For Adolescents In Terms Of Land Use, Food Waste, And Greenhouse Gas Emissions., Lina Elsehelly

Papers, Posters, and Presentations

The current food system is directly responsible for much environmental damage including severe climate change, biodiversity loss, and land scarcity. This research aims to find some strategies to mitigate these damages through diet by specifically targeting adolescents because they are potential problem-solvers. This period is also when personality and habits are articulated. By focusing on reducing greenhouse gas emissions, land use, and food waste, a more environmentally sustainable diet can be formulated. The key findings of the research can be summarized by reducing ultra-processed foods, choosing sustainably produced food, generally reducing meat consumption from the current rate, substituting red and …

Determination Of Cadmium And/Or Drought Stress Effects On Some Plant Phytohormone Contents And Hormone Gene Expressions In Bean (Phaseolus Vulgaris L), Melek Eki̇nci̇, Ertan Yildirim, Güleray Ağar, Esra Arslan Yüksel, Murat Aydin, Selda Örs, Razi̇ye Kul

Turkish Journal of Agriculture and Forestry

Plants can sometimes be under the influence of more than one stress factor. In this case, combined stress factors can cause different responses in plants. In this study, the phytohormonal activity and hormone gene expressions of beans (Phaseolus vulgaris L.) were investigated in different drought levels and soils with different levels of cadmium accumulation. Plants were grown at 4 different cadmium (Cd) levels (Cd: 0, Cd1: 100, Cd2: 150, and Cd3: 200 mg kg$^{-1}$) and 3 irrigation levels (D0: 100%, D1: 75%, and D2: 50% of field capacity).

Up In Smoke: Wildfires And Economic Growth, Nicholas Silvis

Gettysburg Economic Review

Do wildfires have a causal effect on economic development? Using satellite data, I analyze every country's exposure to wildfire exposure from 1982-2018. I use synthetic controls to model the impact of wildfire exposure on GDP per capita having controlled for population density, trade, agriculture, Foreign Direct Investment (FDI), and polity score. I find that the impacts of wildfires are fairly localized, impacting parts of Africa that both experience high numbers of wildfires and are developing.

Impact Of Charging Infrastructure On Electric Vehicle Sales: An Analysis From Counties In 13 Us States, Shubh N. Parekh

Gettysburg Economic Review

Adoption of battery electric vehicles (BEVs), and plug-in hybrid electric vehicles (PHEVs), has become a priority for the government because of the constant threat of climate change. Over the years, government monetary incentives like tax credits, tax rebates, and other monetary subsidies are the leading way to increase electric vehicle sales in the United States. While these incentives are necessary to combat the high costs of electric vehicles (EVs), there hasn’t been too much attention given to combat range anxiety. Since EVs are run on lithium-ion batteries, there is a limited range for different EVs, with the maximum being around …

Application Of The Hvsr Technique To Map The Depth And Elevation Of The Bedrock Underlying Wright State University Campus, Dayton, Ohio, Devika L. Ghuge

Browse all Theses and Dissertations

Estimating sediment thickness and bedrock surface geometry is critical for many hydrogeologic studies. The horizontal-to-vertical spectral ratio (HVSR), a passive seismic method is a unique, non-invasive technique for speedily estimating bedrock depth. To record ambient seismic noise, the H/V method employs a single broadband three-component seismometer. A field assessment was conducted on the Wright State University Campus in Dayton, Ohio, to determine the depth (z) and elevation of the bedrock. Data were collected at 60 different locations. A known value for the depth of bedrock on campus was determined using the log from a local water well available from the …

Effects Of Phosphorus-Binding Agents On Nutrient Dynamics And A Planktothrix Bloom In A Shallow, Semi-Enclosed Lake Area, Joseph Lee Davidson

Browse all Theses and Dissertations

Grand Lake St. Marys is the largest (52 km2) inland lake in Ohio, USA, and receives high nutrient loadings (90th percentile for total nitrogen (N) and phosphorus (P) concentrations in the USA) from a watershed dominated by agricultural row-crops and livestock production. Eutrophication has led to cyanobacterial harmful algal blooms, dominated by non-N2 fixing Planktothrix, that persist year-round, including in winter months. In summer 2020 and 2021, multiple treatments using P-binding agents within a 3.5 ha swimming enclosure were conducted to remove excess dissolved P from the water column. The objective of this study was to examine pre-and-post treatment biogeochemical …

Exploring First Responders' Use And Perceptions On Continuous Health And Environmental Monitoring, Jacob Grothe, Sarah Tucker, Anthony Blake, Chandran Achutan, Sharon J. Medcalf, Troy Suwondo, Ann Fruhling, Aaron Yoder

Journal Articles: Epidemiology

First responders lose their lives in the line of duty each year, and many of these deaths result from strenuous physical exertion and exposure to harmful environmental agents. Continuous health monitoring may detect diseases and alert the first responder when vital signs are reaching critical levels. However, continuous monitoring must be acceptable to first responders. The purpose of this study was to discover first responders' current use of wearable technology, their perceptions of what health and environmental indicators should be monitored, and who should be permitted to monitor them. The survey was sent to 645 first responders employed by 24 …

Dry Spells And Global Crop Production: A Multi-Stressor And Multi-Timescale Analysis, Uchechukwu Jarrett, Steve Miller, Hamid Mohtadi

Department of Economics: Faculty Publications

More frequent and punctuated severe events such as dry spells are among the more salient manifestations of climate change. Because dry spells often co-occur with drought and heat waves, understanding the effects of dry spells and heat waves requires a multi-timescale and multi-stressor perspective. Using a global panel of daily precipitation and temperature from 1979 to 2016, we provide evidence that 4-5 week dry spells that occur during the hottest part of the year depress growth in crop production. The effects of these extreme events are modified by existing drought, aridity, and by heat waves. After accounting for productivity and …
