Enhanced Recent Local Moisture Recycling On The Northwestern Tibetan Plateau Deduced From Ice Core Deuterium Excess Records, Wenling An, Shugui Hou, Qiong Zhang, Wangbin Zhang, Shuang-Ye Wu, Hao Xu, Hongxi Pang, Yetang Wang, Yaping Liu

Department of Earth, Environment and Sustainability Faculty Publications

Local moisture recycling plays an essential role in maintaining an active hydrological cycle of the Tibetan Plateau (TP). Previous studies were largely limited to the seasonal time scale due to short and sparse observations, especially for the northwestern TP. In this study, we used a two‐component mixing model to estimate local moisture recycling over the past decades from the deuterium excess records of two ice cores (i.e., Chongce and Zangser Kangri) from the northwestern TP. The results show that on average almost half of the precipitation on the northwestern TP is provided by local moisture recycling. In addition, the local …

Brain Motion, Deformation, And Potential Injury During Soccer Heading, Charles F. Babbs

Weldon School of Biomedical Engineering Faculty Working Papers

This paper addresses the problem of what is happening physically inside the skull during head-ball contact. Mathematical models based upon Newton’s laws of motion and numerical methods are used to create animations of brain motion and deformation inside the skull.

Initially a 1 cm gap filled with cerebrospinal fluid (CSF) separates the brain from the rigid skull in adults and older children. Whole head acceleration induces a pulse of artificial gravity within the skull. Because brain density differs slightly from that of CSF, the brain accelerates and strikes the inner aspect of the skull, undergoing viscoelastic deformation, ranging from 1 …

Nature, The New Rx, Christina Dabney

Capstones

In 2010, Candice Opperman's job made her sick. The weight of working full-time while going to grad school began to create so much stress and anxiety that she felt like she was being "held down by a lead vest."

In 2013, after three years at Merrill Lynch, Opperman’s doctors diagnosed her with burnout and insisted she go on disability. Thats when she started using nature in her recovery.

Opperman turned to green spaces instinctively, but doctors are increasingly prescribing nature as therapy. Experimental data suggest that parks and open spaces can help heal the human brain, especially from disorders involving …

An Integrated Behavioural Model Towards Evaluating And Influencing Energy Behaviour—The Role Of Motivation In Behaviour Demand Response, Julia Blanke, Christian Beder, Martin Klepal

NIMBUS Articles

The change in the actual use of buildings by its occupants is receiving more and more attention. Over the lifecycle of a building the occupants and therefore the demands towards the buildings often change a lot. To match these altering conditions, particularly in the context of the demand for energy efficiency, purely technical approaches usually cannot solve the problem on their own or are not financially viable. It is therefore essential to take the behaviour of the end user into account and ask the fundamental question: “How is it possible to influence people’s behaviour towards a more pro-environmental outcome, and …

Do Flashbulb Memories Transmit Across Generations? 9/11 As A Case Study, Shanique Meyler

Student Theses

Psychologists have only recently begun to examine the extent to which personal memories transmit across generations. When they have, they typically focus on family stories (see Merrill & Fivush, 2016) or memories of historical events (Svob & Brown, 2012). The present study extends this line of research to flashbulb memories, or memories of an individual’s circumstances when first learning about a consequential, historical event (Brown & Kulik, 1977). To this end, the present study examines the extent to which flashbulb memories surrounding the events of the terrorist attacks on 9/11 transmit to the next generation. The results suggest that flashbulb …

Soil Morphological, Physical, And Chemical Parameters Affecting Longleaf Pine (Pinus Palustris) Site Quality And Ecosystem Restoration Potential In East Texas, Ryan Svehla, Kenneth W. Farrish

Electronic Theses and Dissertations

There has been a large decline in coverage of longleaf pine (Pinus palustris Mill.) within its range in the southeastern United States since the time of European settlement. Due to this decline, interest has developed in the re-establishment of this species on suitable sites. However, many attempts have been unsuccessful in re-establishment, likely in part due to the lack of emphasis on selection of suitable soils. Historically, longleaf pine was found on soils with a wide range of soil properties, including higher quality soils, due to frequent fires which kept many competing species suppressed. Decline in longleaf pine coverage …

Geology Of The Northern Alto Relex Area, Big Bend National Park, Brewster County, Texas, Robert Schoen

Electronic Theses and Dissertations

Detailed, 1:12,000-scale geologic field mapping was conducted around Alto Relex in the northern Sierra Del Carmen Mountains in Big Bend National Park. Alto Relex is a prominent, near vertical, ~1000 foot-high fault-line scarp. Cretaceous rocks in the area were folded and faulted by Laramide compression, intruded by Tertiary sills and overprinted by high-angle normal faults from Basin and Range extension. During the Laramide Orogeny and Basin and Range extension, the underlying basement shear zone called, the Texas Lineament, was reactivated creating a transpressional and transtensional regimes. The general geology of this area was outlined by Moustafa (1988) working primarily from …

Predicted Suitable Habitat Declines For Midwestern United States Amphibians Under Future Climate And Land-Use Change Scenarios, Brock Struecker, Joseph Milanovich

Biology: Faculty Publications and Other Works

With current declines of vertebrate taxa meeting or exceeding those of historic mass extinction events, there is a growing need to investigate the main drivers of losses. Two of the main drivers of declines are global climate and land-use changes, both affecting multiple groups of taxa. Amphibians are at great risk from these two drivers of change and investigations into the impact of future change could assist with the formation of conservation plans to mitigate losses. Forecasting changes in suitable habitat with ecological niche modeling serves as a useful tool to begin to understand how species may respond to anthropogenic …

Expecting The Inevitable: Daca And Mental Health, Jade Gardener

Capstones

On September 5, 2017, Attorney General, Jeff Sessions announced that the Trump Administration was ending the Deferred Action for Childhood Arrivals program. Better known as DACA, the passed into action in 2012 by the administration of former President Obama, was heralded for providing young undocumented adults the ability to do things such as legally work and attend college.

The repeal of DACA is just beginning to affect the mental health of recipients. Researchers contend that the repeal of the DACA is a violent act that thus results in the psychological distress. Citing research published in American Association for the Advancement …

Unseen Science: Modern Discoveries Too Far Away Or Tiny For Human Eyes, Lucy Huang

A Little Known Trade Deal Could Soon Derail America's Booming Solar Industry, Sam Donnenberg

Capstones

A trade deal has been winding its way through hearings at the International Trade Commission for months that could have major consequences for America's solar energy industry. Two solar energy companies are requesting that tariffs be applied to Chinese solar product imports. But industry analysts say this will cause the price of solar to rise and harm the industry during a period of unprecedented growth. The petition has only one stop left on its way to approval: The desk of President Trump.

Of Rats And Men, Thomas S. Walsh

Capstones

This capstone is a data-driven investigation into New York City's rat problem. By using publicly available government data to map rat activity in NYC, I identified several socio-economic variables that correlate with rat populations at the community district, borough, and city-scale. I used these findings (mainly that rat problems are linked to lower incomes) as the basis of an investigation, which includes interviews with residents, experts, and city officials. Prof. Bobby Corrigan, urban rodentologist and formerly with the NYC Department of Health criticizes the city's efforts for the first time on the record.

"Comrades In Their Own Right": Women's Struggle Against Apartheid In The South African Novel, Ntfonjeni Dlamini

Electronic Theses and Dissertations

ABSTRACT

This thesis focuses on women’s struggle against apartheid in the South African novel. By means of textual analysis, the study explores the different ways in which apartheid oppressed women in South Africa and how women responded to the forces of oppression. In fact, at the core of this study is the contention that the anti-apartheid movement was shaped as much by women as it was by men like Nelson Mandela, Walter Sisulu, Steve Biko and Albert Luthuli, who often served as the faces of the anti-apartheid movement. Thus, this thesis situates itself within the scholarship that appreciates and recognizes …

Civil Engineering ETDs

Plastic biofilm carriers are used in biological wastewater treatment to encourage the attachment and retention of microorganisms that metabolize pollutants. The following research was conducted to better understand how different characteristics of the biofilm carrier affect the treatment performance of the attached biofilms in moving bed bioreactors. Lab scale reactors were used in this study to grow nitrifying biofilms in reactors with contrasting and controlled conditions. The effect of surface geometry on nitrification performance was evaluated by testing commercially available moving bed bioreactor media that contrast in physical design, and by varying operational parameters. Additionally, mature biofilm from a similar …

Quantifying The Effect Of Construction Site Factors On Concrete Quality, Costs And Production Rates, Jorge L. Santamaria

Civil Engineering ETDs

Factors affecting concrete can be categorized as structured factors or unstructured factors. The first group of factors consists of those related to the production process of concrete including water-cement ratio, properties of raw materials and mix proportions. Unstructured factors or construction site factors are related to labor skills and local conditions during the construction process of a project. Concrete compressive strength as a quality metric, costs and production rates may be affected significantly by such factors while performing concrete operations at the jobsite. Several prior studies have investigated the effect of structured factors on concrete. However literature is limited regarding …
