Faculty Publications

Ultraviolet (UV) radiation can damage DNA and kill cells. We use laboratory and observational studies of the harmful effect of UV radiation on marine photosynthesizers to inform the implementation of a UV radiation damage function for phytoplankton photosynthesis in a modified version of the Community Earth System Model version 2 (CESM2-UVphyto). CESM2-UVphyto is capable of simulating UV inhibition of photosynthesis among modeled phytoplankton and ocean column penetration of UV-A, UV-B, and UV-C radiation. We conduct a series of simulations with CESM2-UVphyto using the Marine Biogeochemistry Library (MARBL) ecosystem model to understand the sensitivity of phytoplankton productivity to UV radiation.

A Data-Efficient Approach For Monitoring And Modeling Stream Nutrients, Wasif Bin Mamoon

Dissertations (1934 -)

Streams and rivers with excessive nutrients can compromise aquatic ecosystems, human health, and overall water resources. Precise, high-resolution measurements of nutrient concentrations are essential for pollution management programs; however, conventional monitoring methods frequently face limitations due to cost and sample restrictions. This dissertation aimed to advance the existing state-of-the-science nutrient monitoring and modeling approaches to reduce sampling requirements and model complexity. First, this study estimated the dimensionality and predictability of nutrient signals (NOx and TP signals), that describe the nutrient dynamics. The findings showed that nutrient data can be forecasted accurately for 1 to 5.5 months. Most of the signals …

Conditions Of Coherent-Phonon Excitation In Srmnsb2 Films And Crystals, Manita Rai, Sujan Subedi, Hannah E. Aguirre, Hans A. Bechtel, Renee Chapla, Javier Garcia De Castro, Dennis D. Klug, Jinyu Liu, Madison G. Masten, Trung Hieu Nguyen, Thomas J. Rehaag, Yiyi Wang, Zhiqiang Mao, Gavin R. Bell, Darius H. Torchinsky, Christopher Weber

Physics

Excitation of coherent phonons has the potential to dramatically alter the electronic structure of Dirac and Weyl semimetals, enabling sub-picosecond control of their optical and electronic properties. The Dirac semimetal SrMnSb is a candidate for such control, with a coherent-phonon mode that is predicted to close and reopen a gap at the Dirac node. Here, through a series of ultrafast pump-probe experiments, we establish suitable samples and conditions for driving the coherent phonon to high amplitude and attempting to observe the gap’s closure. Films of SrMnSb grown by molecular-beam epitaxy are shown to have phononic properties matching those of bulk …

To collect data, we engaged with two categories of informants: primary informants (traditional healers) and secondary informants (native Lomongo speakers). Ethnobotanical and ethnolinguistic surveys were conducted in the “Elandisha” Mavaolo area through participant observation, semi-structured interview guides, audio recordings, and photographs. The plants identified were documented in situ with the assistance of botanists from "Matiti-Lisanga," an interdisciplinary …

Decoding Omens From Animal Calls And Sightings: An Ethnozoolinguistic Study Among The Iraqw Of Tanzania, Chrispina Alphonce

Journal of Humanities and Social Sciences

Understanding the interplay between cultural beliefs, language, and environmental signals is crucial for comprehending how communities engage with their natural surroundings. Despite existing research on cultural interpretations of natural phenomena, little is known about how animal calls and sightings specifically predict omens within the Iraqw community in Tanzania. This study examines the Iraqw ethnozoolinguistics of omens, focusing on their role in forecasting social events, both positive and negative, and on how these signals reflect the community’s cultural understanding. A qualitative research design was employed, with data collected through introspection, focus group discussions, and semi-structured interviews, grounded in ecosemiotic, ecolinguistic, and …

Morphological And Semantic Analysis Of Plant Names Attested In Hehe Language In Tanzania, Onesmo Simon Nyinondi

Journal of Humanities and Social Sciences

This paper examines the morphological structure of plant names in Hehe, a Bantu language spoken in the Iringa Region of Tanzania, specifically in the rural areas of Mufindi and Kilolo districts, involving 169 participants. Data were collected through free listings, field interviews (also known as walk-in-the-woods interviews), focus group discussions, and the analysis of written texts containing Hehe plant names. The study shows that Hehe plant names consist of a noun class prefix and a noun stem, with most falling into the 3/4 and 5/6 pairs. Some plant names are also categorised in the 7/8, mainly small plants, and 9/10 …

What Is In A Plant Name? A Semantic Analysis Of Indigenous Plant Names Among The Yao Of Southern Tanzania, Julius John Taji

Journal of Humanities and Social Sciences

This study investigates the meanings conveyed by indigenous plant names among the Yao of Masasi, southern Tanzania, whose native language is Chiyao (Bantu, P21).
