Inspection And Understanding Of Sewer Network Condition In Dindaeng District (Thailand), Hnin E. Phyu, Sutha Khaodhiar

Applied Environmental Research

Sewer pipelines are usually operated with little maintenance after installation. After years in service, sewer pipes get old and deteriorated.  The present research is the first study that attempts to inspect the condition of sewer pipelines in the Bangkok Metropolitan Area. A robot with Closed Circuit Television (CCTV) was used to capture videos and images of the interior of the sewer pipelines between two manholes. The system was operated by Utility Business Alliance (UBA) Company. The condition of the sewer pipelines was visually analyzed in line with the scoring and grading system of New Zealand’s pipe inspection manual. CCTV footage …

Consequence Of Seawater Intrusion On Soil Properties In Agricultural Areas Of Nonthaburi Province, Thailand, Napaporn Phankamolsil, Kiattisak Sonsri, Yutthana Phankamolsil

Applied Environmental Research

Seawater intrusion associated with climate change and sea level rise (SLR) has been postulated for the last decade that causes negative impact on worldwide environmental resources. In Thailand, however; the information pertaining to its effect on soil properties in agricultural areas has not been clearly reported yet. Hence, this study aimed to investigate the seawater intrusion effect on soil properties in agricultural areas of Nonthaburi Province, Thailand. Five study locations, which anticipated to be affected by seawater intrusion, were selected based on the different distances from the Chao Phraya River. Soil morphological properties were recorded, besides undisturbed soil samples at …

Applied Environmental Research

The focus of this study was to portray the spatial pattern of air quality across seasons in the eight sampled farm settlements using air quality indexes and assess the clusters of monitored air pollutants. The concentrations of air pollutants were determined using in-situ portable gas detectors and particulate counter. The AQI for each criteria pollutants (CO, O3, TSP, PM10, SO2, and PM2.5) was calculated using AQI formulae of the United States Environmental Protection Agency and mapped using the Inverse distance weighting (IDW) interpolation method in the Geographic information systems (GIS) environment. Principal component analysis (PCA) was used to group the …

Treatment Of Iron From Groundwater By Ozonation: Influence Of Hardness As A Scavenger, Apiradee Sukmilin, Ratsamee Sangsirimongkolying

Applied Environmental Research

This study assesses the efficiency of using ozone technology to treat iron from groundwater while hardness acts as a radical scavenger. Batch experiments were conducted to determine the effects of initial pH 6, 7 and 8, and hardness of 300, 400 and 500 mg L-1 and kinetic analysis. The optimum conditions were found to be initial pH of 8 and hardness of 300 mg L-1. The removal efficiency of iron by ozonation was 99.97%, which was higher than that of air without ozone applied (83.67%). However, the presence of hardness and tert-butanol (TBA) had a negative effect on the …

Source And Distribution Of Polycyclic Aromatic Hydrocarbons (Pahs) In Surface Sediment From Chalong Bay, Phuket, Thailand, Danai Tipmanee, Yada Patchim, Penjai Sompongchaiyakul

Applied Environmental Research

This study aimed to investigate the spatial distribution and apportionment of potential sources of the 16 US-EPA priority PAHs in surface sediments of Chalong Bay, Phuket, Thailand. A total 28 of sediment samples were collected from areas with high maritime activity in Chalong Bay, subjected to conventional high recovery Soxhlet extraction, purified with SiO2 column chromatography, and quantified by Gas Chromatography-Mass Spectrometry (GC/MS). Total concentration of PAHs (Σ16PAHs) ranged from 31.15 to 1696 ng g−1 dry weight, with an average of 198.2 ± 318.5 ng g−1 dry weight. Binary diagnostic ratios plots were used to distinguish between petrogenic and pyrogenic …

Willingness To Pay For Improving Household Solid Waste Management In Vietnam, Phan C. Chinh, Nguyen T.Q. Hung, Nguyen M. Ky, Nguyen T.L. Ai, Nguyen M. Tam

Applied Environmental Research

Management of solid waste is a major challenge in urban areas of most parts of the world, especially in developing countries. The study aimed to determine and estimate the willingness to pay (WTP) of the selected households for the improvement of solid waste management in Vietnam. The research evaluated WTP of household solid waste in case studies in Bien Hoa and My Tho cities using contingent valuation method (CVM). The data were collected through a closed-ended questionnaire survey and interviews with 200 households. The results showed that the most willingness to pay was equal to 10,000 and 15,000 VND per …

Current Trends In Steroidal 17Α-Ethynylestradiol (Ee2) Removal From The Environment: A Review, Wasiu A. Abibu, Gafar Bamigbade, Amos O. Kolawole, Taiwo Ajayi, Abdul W. Sakariyau

Applied Environmental Research

Emerging contaminants have posed major environmental and health challenges to human and aquatic lives. They include pharmaceuticals, endocrine disrupting compounds (EDCs), persistent environmental pollutants and many more. EE2 is an example of an endocrine disrupting compounds (EDCs) increasingly gaining acceptance and used to augment the deficiencies of other reproductive hormones. EE2 constitutes environmental nuisance via discharge into aquatic bodies, thus, threatening aquatic lives and resulting in health defects in human. It is worthy of note that previous researchers have channeled their studies to identifying ways of expelling EE2 from the environment. However, they remain persistent in the environment. The current …

Tackling Regional Climate Change And Food Security Issues: An Introduction, Md. Saidul Islam, Edson Kieu

Research Collection Lee Kong Chian School Of Business

Regional organizations are central to effectively addressing the current and future impacts of climate change and food security issues. Climate change and food security issues can only be dealt with through extensive policies that adopt a multi-sector, multi-stakeholder approach. An examination of three regional organizations (the Association of Southeast Asian Nations, the Pacific Islands Forum, and the South Asian Association for Regional Cooperation) can provide new insights into current climate change mitigation policies that will ensure food security for future generations. This opening chapter thus begins with the premise that regional organizations are optimally positioned to address climate change and …

Tribal Revegetation Project Final Project Report: 92-Acre Area, Area 5 Radioactive Waste Management Complex, Nevada National Security Site, Nevada, Jeremy Spoon, Brittany Kruger, Richard Arnold, Kate Monti Barcalow, Tribal Revegetation Committee, Trc

Anthropology Faculty Publications and Presentations

Nuwu (Southern Paiute), Newe (Western Shoshone), and Nuumu (Owens Valley Paiute) are linguistically related, Numic-speaking peoples who are part of the broader Uto-Aztecan language group. Numic peoples view the land as a holistic, living, sentient being with feelings and purpose. The land is personified with human characteristics and it needs to be experienced to be understood through “learning by doing.” Numic peoples do not support ground disturbing activities within their ancestral lands, including activities tied to the storage of low-level radioactive waste or classified materials on the NNSS, which they view as culturally inappropriate. These deep-rooted ancestral connections are the …

Determinates Of Georgia White-Tailed Deer Harvests, Evan W. Page

Honors College Theses

This manuscript provides recent evidence regarding the determinates of white-tailed deer harvest densities in the state of Georgia. The data from the 2016/17-2020/21 deer hunting seasons indicates total deer harvest density is positively influenced by the prior year’s mature buck harvest density, the turkey harvest density, higher unemployment rates, higher median incomes, and a higher level of education. Deer harvest density was found to be negatively impacted by larger public land harvests the year before and greater human population densities.

Biological Invasions In Coastal Marine Ecosystems: How Changes In Trade Are Linked To Ballast Water Delivery Of Nonindigenous Species, Danielle Elizabeth Verna

Dissertations and Theses

Globalization has escalated transfers of nonindigenous species (NIS) across natural dispersal barriers. The resulting biological invasions have become a leading global mechanism of ecological change. NIS are often transported between coastal marine ecosystems in the ballast water of commercial ships, and patterns of NIS introduction and establishment can be linked to global trade dynamics. Here I examined drivers of trade and ballast water across spatial and temporal extents of invasion. The analyses incorporated a variety of datasets on trade, industries, and ship behavior to identify fluctuations in globally transported commodities that lead to changes in maritime shipping patterns and frequency. …

Building City Identities: A Consumer Perspective, Delphine Godefroit-Winkel, Marie Schill, Cristina Longo, Martin Chour

Markets, Globalization & Development Review

This study complements current knowledge on city identity and city attachment through a phenomenological inquiry among 22 Casablanca consumer residents. Five Casablanca identities emerge: City of Escape, Busy Isolating City, Clustering City, Small City, and Dark City. The findings illuminate (1) how consumers build specific types of city identities; (2) demonstrate city identity as the outcome of interplays between various consumption experiences, perceived characteristics of spaces and places, and ambivalent emotions; and (3) update current knowledge on city attachment. This work further provides valuable recommendations to public authorities who are willing to leverage specific identities.

Ecological Risk Assessment Of Managed Relocation As A Climate Change Adaptation Strategy, Aviv Karasov-Olson, Mark W. Schwartz, Julian D. Olden, Sarah Skikne, Jessica J.

Executive Summary

Changing climate and introduced species are placing an increasing number of species at risk of extinction. Increasing extinction risk is increasing calls to protect species by relocating, or translocating, them to locations with more favorable biotic or climatic conditions. Managed relocation, or assisted migration, of species entails risks to both the conservation target organisms being moved as well as the recipient ecosystems into which they are moved.

Recognizing this risk, calls have been made for practitioners interested in considering a managed relocation project to engage in a serious risk assessment prior to advancing a project. We engaged a …

Protocol For Monitoring Fish Communities In Small Streams In The Heartland Inventory And Monitoring Network, Version 2.0, Hope R. Dodd, David G. Peitz, Gareth Rowell, Janice A. Hinsey, David E. Bowles, Lloyd W. Morrison, Michael D. Debacker, Jennifer L. Haack-Gaynor, Jeffrey M. Williams

United States National Park Service: Publications

Executive Summary

Fish communities are an important component of aquatic systems and are good bioindicators of ecosystem health. Land use changes in the Midwest have caused sedimentation, erosion, and nutrient loading that degrades and fragments habitat and impairs water quality. Because most small wadeable streams in the Heartland Inventory and Monitoring Network (HTLN) have a relatively small area of their watersheds located within park boundaries, these streams are at risk of degradation due to adjacent land use practices and other anthropogenic disturbances. Shifts in the physical and chemical properties of aquatic systems have a dramatic effect on the biotic community. …

Cultivated Wild: Enhancing Human Health In Cities Through Green Projects Especially During A Pandemic, Glenn Rose

Environmental Studies Senior Seminar Projects

The University of Richmond Eco-corridor, a new renovation project, transformed a wildly overgrown area into one of beauty with several recreational uses. The opening of this project comes at an important time for local outdoor recreation in cities, the COVID-19 pandemic. Previous work has suggested that landscapes are more beautiful when there is minimal human impact, therefore wilderness scenes are more likely to be used for nature walks and observing nature. While other studies suggest that beauty is dependent on how the land may be used, suggesting that “cultivated wild” is preferrable. This paper used an observational study and a …

Comparing The Environmental Impacts Of Using Mass Timber And Structural Steel, Khang Hoang Nguyen, Steelee Knight Morgan

Construction Management

Although mass timber has seen a gradual rise in demand in the past, there has been a lack of extensive research on the environmental impacts of using mass timber as a primary structural framing material. This paper compares structural steel, and mass timber’s total embodied carbon emissions. Accurate estimates were made using plans and specs for different projects retrieved from semi-structured interviews. The estimates were input through the EC3 Calculator to provide extensive total carbon emissions measurements between each construction material. Using structural steel framing increased the project’s overall environmental impact by roughly 84% compared to using mass timber. The …

The Road Ahead, Chloe Tilley

Bryant University Undergraduate Journal

The creative project that I chose to make is a visual representation on the website “Creately” where I created a map of categorizations. I call the map that I created “The Road Ahead.” There are three sections, “where we were”, “where we are”, and “where we’re going”, and within these grounds I made a bank of major concepts and key terms that we have studied and explored throughout this semester; the map is essentially a word bank and concept organization of all the ideas from this course that were discussed and were threaded through the readings. The structure that I …

Living In The Plantationocene, Joshua Turner

Bryant University Undergraduate Journal

Preceding centuries of exploitation and commodification of all life and the natural world have led us to the crises we face today. To describe the dramatic changes our species has forced upon the planet, in 2000, scientists Eugene Stormer and Paul Crutzen dubbed the geological epoch we inhabit the Anthropocene (Global Change Newsletter). Although the term is useful to distinguish the altered composition of the atmosphere, soil, and oceans that human activity has produced from the ecological baseline of the Holocene, some scholars are critical of the term. Not all humans are equally to blame for the environmental degradation which …

Life As It Is, And Where I Want It To Be, Christopher Black

Bryant University Undergraduate Journal

Are you living a purposeful life? Ask yourself this regularly, and you will find yourself embarking on an expedition for passion; Is this not what we should be searching for each and every day? The word “purpose” can be defined as the reason why we do things. Without purpose we are essentially blind in all of our endeavors. At the beginning of every executive summary, at the forefront of every entrepreneurial venture, and within the crux of our hearts, lies purpose. Discovering your purpose is said to harvest empowerment, fluffiness, and happiness.

The Complicated Family Reunion, Cameron Chabot

Bryant University Undergraduate Journal

Plastic has a complicated beginning and an even more complicated future. It is made from substances call polymers and while some can be made from plant cellulose, many now are synthetic polymers made up of petroleum and other fossil fuels. Most fossil fuels are formed from the fossilized, buried remains of plants and animals that lived millions of years ago, so it is quite disturbing that they are being used for plastics that get thrown away after one use. This story follows a six pack of bottles (The Cola Family) and their different journeys around the world after being discarded.

Shannon Soundscape, Satrina-Mae Shannon

Bryant University Undergraduate Journal

As a commuter student who does not live on campus, I elected to sit on my back patio for this listening exercise. While I had initially thought that staying relatively close to my house would be somewhat redundant in terms of what I would hear, I was pleasantly shocked to hear just how many sounds, be it human or nonhuman, ring out on my street in a given moment. Looking back, I think I had just never taken the time to actually listen to them.

I live near many trees, so the sound of birds chirping, or squirrels climbing is …

Morrison Soundscape, Ellie Morrison

Bryant University Undergraduate Journal

I am staying in an apartment in the Museum District of Philadelphia, so I went to the courtyard in the middle of the property. I took some snacks with me, took the elevator to the ground floor, then walked outside and chose a white Adirondack chair in the middle of the grass. Being in a big city, I heard much more man-made, urban sounds than I did clean, natural sounds.

The first thing I noticed was the low, almost throaty, rumble of motorcycles on the freeway not even 200 yards away. It came in non-metrical bursts for the first minute …

Leszczynski Soundscape, Joseph Leszczynski

Bryant University Undergraduate Journal

Sitting outside of the Fisher Student Center, on black lacquered chairs, was the location of my soundscape experience. Being outside and an epicenter of activity, the amount of noise there was abundant. I was still outdoors, thus explaining the neutral noise of the environment. Some of the natural, non-human sounds I heard were from insects. A distinct, crescendo buzz came from above in the trees. The timbre was brash, like a trumpet that hit a high pitch note with vibrato. In addition, there were occasions where dried leaves would hit the ground from falling off a branch. This noise was …

Donlan Soundscape, Christopher Donlan

Bryant University Undergraduate Journal

To capture the soundscape, I spent some time on the patio behind my apartment building and was able to identify a number of sounds, both natural and manmade. The location I was at sits right along the Blackstone River however, so the sound of the running water generates lots of white noise. While not changing in rhythm or pitch, the water produced a smooth and subtle tone that slightly masks the other sounds.

The most prominent sound I heard was the chirping from crickets. Their sound has a very fast paced rhythm that occurs in a steady pattern, however the …

A Typical Afternoon In The Hustling Streets Of Mumbai, Ishan Mehta

Bryant University Undergraduate Journal

This soundscape activity is going to give you an experience of a typical afternoon in the hustling streets of Mumbai. I live on the 18^th floor of an apartment building in a suburb called Versova. One may think that staying at a higher floor would mean that there would be less sound, but in reality sound travels up through the building and you can hear everything. Since I could not go out of the house I walked around in my balcony which faces the ocean and right under is the main street, this is what I could hear. As …
