The Acoustic Camera As A Tool To Identify Belt Conveyor Noises, Piotr Bortnowski, Anna Nowak-Szpak, Maksymilian Ozdoba, Robert Król
Journal of Sustainable Mining
This paper explores the possibilities of using an acoustic camera as a tool that allows the verification of the correct construction and operation of individual elements of a belt conveyor. Based on the simultaneously recorded components - a video camera and measuring microphones, the sound pressure level map of the belt conveyor was created. The tests were carried out in laboratory conditions and covered the location and identification of individual noise sources. The verification consists not only of searching for dominant sound sources, but above all, of searching for frequencies in the analysed spectrum that should not occur during their proper ...
A Systematic Review Of The Use Of Environmental Economics In The Mining Industry, 2021 National Technical University of Athens
A Systematic Review Of The Use Of Environmental Economics In The Mining Industry, Maria Menegaki, Dimitris Damigos
Journal of Sustainable Mining
Environmental economics is increasingly being used in project appraisals, environmental liability estimates and design of market-based instruments. Mining, an actor capable of causing adverse effects on the environment, human health and well-being, has already been affected by these developments, at a great extent. Up to date, several research studies have been carried out to monetise the externalities of mining projects. Nevertheless, a systematic review of these publications has not been carried out, yet. This paper aims to fill this gap in the literature by investigating (i) the main non-market valuation techniques used; (ii) the main external costs or benefits of ...

The Feasibility Of Over-Summer Snow Storage At The Craftsbury Outdoor Center, Craftsbury Vt, 2021 University of Vermont
The Feasibility Of Over-Summer Snow Storage At The Craftsbury Outdoor Center, Craftsbury Vt, Hannah Sarah Weiss
Graduate College Dissertations and Theses
Climate change increases the unpredictability of winter weather and threatens the future of nordic skiing. Ski centers at high elevation and high latitude have employed over-summer snow storage, a climate change adaptation strategy, to ensure a consistent start-date to their winter ski season. Over-summer snow storage involves making a large pile of snow during winter and storing the snow beneath protective layers, such as wood chips or foam panels, to impede melt throughout the summer and fall. When ready to open the ski season, the ski center uncovers the pile and spreads the snow to create trails. Though many nordic ...
Local Climate Action Planning As A Tool To Harness The Greenhouse Gas Emissions Mitigation And Equity Potential Of Autonomous Vehicles And On-Demand Mobility, Serena Alexander, Asha Weinstein Agrawal, Benjamin Y. Clark
Mineta Transportation Institute Publications
This report focuses on how cities can use climate action plans (CAPs) to ensure that on-demand mobility and autonomous vehicles (AVs) help reduce, rather than increase, green-house gas (GHG) emissions and inequitable impacts from the transportation system. We employed a three-pronged research strategy involving: (1) an analysis of the current literature on on-demand mobility and AVs; (2) a systematic content analysis of 23 CAPs and general plans developed by municipalities in California; and (3) a comparison of findings from the literature and content analysis of plans to identify opportunities for GHG emissions reduction and mobility equity.
Findings indicate that maximizing ...

The Prediction Of Calorific Value Of Carbonized Solid Fuel Produced From Refuse-Derived Fuel In The Low-Temperature Pyrolysis In Co2, 2021 Wrocław University of Environmental and Life Sciences
The Prediction Of Calorific Value Of Carbonized Solid Fuel Produced From Refuse-Derived Fuel In The Low-Temperature Pyrolysis In Co2, Ewa Syguła, Kacper Świechowski, Paweł Stępień, Jacek A. Koziel, Andrzej Białowiec
Agricultural and Biosystems Engineering Publications
The decrease in the calorific value of refuse-derived fuel (RDF) is an unintended outcome of the progress made toward more sustainable waste management. Plastics and paper separation and recycling leads to the overall decrease in waste’s calorific value, further limiting its applicability for thermal treatment. Pyrolysis has been proposed to densify energy in RDF and generate carbonized solid fuel (CSF). The challenge is that the feedstock composition of RDF is variable and site-specific. Therefore, the optimal pyrolysis conditions have to be established every time, depending on feedstock composition. In this research, we developed a model to predict the higher ...

Use Of Image Processing Algorithms For Mine Originating Waste Grain Size Determination, 2020 Central Mining Institute
Use Of Image Processing Algorithms For Mine Originating Waste Grain Size Determination, Sebastian Iwaszenko
Journal of Sustainable Mining
The utilization of mineral wastes from the mining industry is one of most challenging phases in the raw materials life cycle. In many countries, there are piles of mineral waste materials that date back to the previous century. There is also a constant stream of accompanying mineral matter excavated during everyday mine operation. This stream of waste matter is particularly notable for deep coal mining. Grain size composition of waste mineral matter is one of most important characteristics of coal originating waste material. This paper presents the use of image analysis for the determination of grain size composition of mineral ...
How Can Employers Contribute To Reducing Commuter-Generated Carbon Emissions? Evaluating Employer-Provided Commuter Benefits In Cambridge, Ma, 2020 University of Massachusetts Amherst
How Can Employers Contribute To Reducing Commuter-Generated Carbon Emissions? Evaluating Employer-Provided Commuter Benefits In Cambridge, Ma, Mary Richards
Encouraging a more sustainable commuter mode shift and improving urban transportation systems have the potential to reduce anthropogenic greenhouse gas emissions (GHGs), a major contributor to climate change. Replacing some single-occupancy vehicle (SOV) trips with alternative modes of transportation, such as public transit, walking, or bicycling, represents one approach to begin reducing transportation-related emissions. Collectively, these shifts in transportation patterns would help to reduce the negative social, economic, and environmental costs associated with high rates of personal vehicle use. Employer-provided benefits programs have the potential to influence commuter behavior by making sustainable, alternative commuting choices a more convenient and economically ...
Enforcing Higher Standards For Flood Hazard Mitigation In Vermont, 2020 University of Massachusetts Amherst
Enforcing Higher Standards For Flood Hazard Mitigation In Vermont, Tamsin Flanders
The state of Vermont faces increasing risk of costly damage from catastrophic flooding events as climate change increases the frequency of heavy rains and cumulative precipitation. In addition to increasing flood inundation risk, extreme precipitation events are leading to high rates damage from fluvial erosion—erosion caused by the force of floodwater and the materials it carries. As in all U.S. states, flood hazard governance in Vermont is shared by multiple levels of government and involves a complex compliance model that relies on local governments to regulate private property owners to achieve community, state, or federal goals.
To encourage ...

Many studies examine the correlation between the use of resources such as water, energy and land, and the production of food. These nexus studies focus predominantly on large scale systems, often considering the social dimensions only in terms of access to resources and participation in the decision- making process, rather than individual attitudes and behaviours with respect to resource use. Such a concept of the nexus is relevant to urban agriculture (UA), but it requires customisation to the particular characteristics of growing food in cities, which is practiced mainly at a small scale and produces not only food but also ...
Elucidating The Role Of Hydrogen Bond Donor And Acceptor On Solvation In Deep Eutectic Solvents Formed By Ammonium/Phosphonium Salts And Carboxylic Acids, 2020 Iowa State University and Ames Laboratory
Elucidating The Role Of Hydrogen Bond Donor And Acceptor On Solvation In Deep Eutectic Solvents Formed By Ammonium/Phosphonium Salts And Carboxylic Acids, Muhammad Qamar Farooq, Gabriel A. Odugbesi, Nabeel Mujtaba Abbasi, Jared L. Anderson
Deep eutectic solvents (DESs) constitute a rapidly emerging class of sustainable liquids that have been widely studied and employed in chemical separations, catalysis, and electrochemistry. The unique physicochemical and solvation properties of DESs can be highly tailored by choosing the appropriate hydrogen bond acceptor (HBA) and hydrogen bond donor (HBD). Understanding the role of the HBA and HBD on the multiple solvation interactions in DESs is important to enable their judicious selection for particular applications. This work constitutes the first study to exploit chromatography to measure solute–solvent interactions of DESs using a wide array of known probe molecules. The ...

The Bay Area Rail System: A Sustainable Network Or A Social Equity Phenomenon?, Whitney Libunao
Master's Projects and Capstones
Sustainable transportation, as it relates to sustainable development, aims to achieve economic stability, social equity, and environmental preservation via transit projects. However, gentrification processes and transit-oriented developments or TODs have attracted more households inward toward reinvested transit-centric areas. The San Francisco Bay Area, California has continued to see positive economic growth, with that, higher-income households inhabiting more centralized locations. Native low-income residents have started to feel displacement pressures on both a social and economic scale. Over time, displacement risk inevitably leads to residential displacement where low-income families are forced to relocate to distant, more affordable neighborhoods. As more distance separates ...
Corn And Soybean Response To Wastewater-Recycled Phosphorus Fertilizers, 2020 University of Arkansas, Fayetteville
Corn And Soybean Response To Wastewater-Recycled Phosphorus Fertilizers, Shane Ylagan
Crop, Soil and Environmental Sciences Undergraduate Honors Theses
The ability to recycle phosphorus (P) from wastewaters could provide a sustainable, continuous source of P that might also help protect surface water quality from P enrichment. The mineral struvite (MgNH4PO4·6H2O) is an understudied material that can be created from Pcontaining wastewater and has been shown to have agricultural fertilizer value. The objective of this study was to evaluate the effects of electrochemically precipitated struvite (ECST), chemically precipitated struvite (Crystal Green; CG), diammonium phosphate (DAP), monoammonium phosphate (MAP), rock phosphate (RP), and triple super phosphate (TSP) on corn (Zea mays) and soybean (Glycine max) response in a 79-day greenhouse ...

Characterizing wildfire regimes where wildfires are uncommon is challenged by a lack of empirical information. Moreover, climate change is projected to lead to increasingly frequent wildfires and additional annual area burned in forests historically characterized by long fire return intervals. Western Oregon and Washington, USA (westside) have experienced few large wildfires (fires greater than 100 hectares) the past century and are characterized to infrequent large fires with return intervals greater than 500 years. We evaluated impacts of climate change on wildfire hazard in a major urban watershed outside Portland, OR, USA. We simulated wildfire occurrence and fire regime characteristics under ...
