Effect Of Waste Covid-19 Masks On Compaction Characteristics Of Silty-Clay Soil, Sydney K. Lawson
Effect Of Waste Covid-19 Masks On Compaction Characteristics Of Silty-Clay Soil, Sydney K. Lawson
Honors College Theses
The present study aims to explore the effect of adding shredded waste Covid-19 masks to silty-clay soil on the soil’s compaction characteristics for beneficial use in embankment, the subgrade of roadways, or backfill. This was accomplished by using two different types of masks: blue surgical masks and KN95 masks. Both mask types were hand shredded into half-inch sections using safety-scissors. The maximum dry density (MDD) and optimum moisture content (OMC) are the two most important compaction characteristics, and they were determined by the Standard Proctor Compaction Test (ASTM D698 / AASHTO T99). The change of both the MDD and OMC …
Physical And Stochiometric Controls On Nutrient Uptake And Ecosystem Respiration In Contrasting Sites, Jancoba K. Dorley
Physical And Stochiometric Controls On Nutrient Uptake And Ecosystem Respiration In Contrasting Sites, Jancoba K. Dorley
Civil Engineering ETDs
Meteorological, hydrological, and biogeochemical processes naturally control stream ecosystems. These processes define the frequency and distribution of precipitation and the supply and demand of solutes and particles to support aquatic food chains through space and time. Studies have also found that stream ecosystems are also controlled by anthropogenic activities, which occur on a much shorter timescale. These anthropogenic activities affect stream ecosystems' structure and function from local to planetary changes to the environment. It is essential for scientists and engineers to understand the relationships between naturally occurring processes and those created by human activities for a better interpretation of stream …
Analyzing Video And Isobus Data To Understand Risk And Safety Practices For Roadside Mowing, Nathan Sprague, Timothy Wiegman, J. T. Evans
Analyzing Video And Isobus Data To Understand Risk And Safety Practices For Roadside Mowing, Nathan Sprague, Timothy Wiegman, J. T. Evans
Graduate Industrial Research Symposium
In Indiana, roadside mowing covers 11,200 miles, presenting significant risks. The Indiana Department of Transportation (INDOT) seeks safer methods, including automated evaluations and autonomous robots. Analyzing 120 hours of video and ISOBUS data, we quantify mower interactions with the road and obstacles, finding mowers on -road up to 91% of the time in rural areas and 57% on highways. Key obstacles identified include signs and posts. This research aids in developing risk assessment models and safety evaluations, aiming to improve mowing safety and efficiency, and it supports future development of autonomous mowing technologies.

Graduate Industrial Research Symposium
Purdue University's service-learning course, Water Supply in Developing Countries (WSDC) is dedicated to ensuring access to safe drinking water in the La Vega region of the Dominican Republic. The focus in the current academic year is to enhance the functionality, sustainability, and independence of community-based water treatment systems installed by previous WSDC students. Despite the construction of four water systems since 2012, operational challenges ensued, rendering them currently inoperable. Our objective is to learn from past mistakes, restore the systems and ensure their continuous functionality. During the fall semester, class members assessed repair needs in two communities with existing systems, …
Statistical Analysis For Water Quality Data Using Anova (Case Study- Lake Burullus Influent Drains), Mohamed Hussein Hegazy
Statistical Analysis For Water Quality Data Using Anova (Case Study- Lake Burullus Influent Drains), Mohamed Hussein Hegazy
Civil Engineering
Lake Burullus is considered one of the most valuable northern lakes in Egypt due to its unique ecological system and special location. Over the past four decades, the lake has suffered from high contamination levels due to expansion in fish farming and increasing of agricultural drainage water entering the southern side of the lake through eight influent drains. This research aims to assess the current situation of the lake’s influent drains. For this purpose, two types of statistical analysis, Mean average method, and Analysis of Variance (ANOVA) were used. The water quality conditions for six major drains (Therah (Tira), Nashart, …
Optimizing Anaerobic Digestion Of Food Waste And Industrial Sludge For Biogas Production, Emma R. Murray
Optimizing Anaerobic Digestion Of Food Waste And Industrial Sludge For Biogas Production, Emma R. Murray
Honors College Theses
Food waste is a major contributor to municipal solid waste, and its disposal at landfills has significant environmental and economic impacts. Opportunities need to be identified for the sustainable management of food waste at large scales. Pulp and paper mills throughout the country commonly use anaerobic digestion to treat their waste sludge; however, this sludge can consist of over 50% lignin, which is slowly or negligibly digested. This research aims to explore the sustainability of co-digestion of food waste and paper mill sludge. Lab-scale studies were used to assess the feasibility of anaerobic digestion by measuring treatment efficiencies and biogas …
