Spatially Resolved Kinematics Of Slacs Lens Galaxies. I. Data And Kinematic Classification, Shawn Knabel, Tommaso Treu, Michele Cappellari, Anowar J. Shajib, Chih-Fan Chen, Simon Birrer, Vardha N. Bennert

Physics

We obtain spatially resolved kinematics with the Keck Cosmic Web Imager (KCWI) integral-field spectrograph for a sample of 14 massive (11 < log₁₀(M₍★₎/M☉) < 12) lensing early-type galaxies at z ∼ 0.15–0.35 from the Sloan Lens ACS (SLACS) Survey. We integrate kinematic maps within the galaxy effective radius and examine the rotational and dispersion velocities, showing that 11/14 can be classified as slow rotators. The data set is unprecedented for galaxy-scale strong lenses in terms of signal-to-noise ratio (S/N), sampling, and calibration, vastly superseding previous studies. We find the primary contributions to systematic uncertainties to be the stellar template library and wavelength range of the spectral fit. Systematics …

Facilitation Of Focus Groups Towards Conflict Resolution Among Pastoralists And Farmers In Northern Uganda: An Indigenous Relational Approach, Francis Akena Adyanga Dr., Norma Ra Romm Prof., Ambrose Dbins Toolit

The Qualitative Report

In this article we discuss how we explored with participants in a district of Northern Uganda certain land-related conflicts between pastoralists (herdsmen) and farmers. Following the end of the conflict in the civil war in Northern Uganda (1986-2006/7), many pastoralists moved from Central and Western Uganda to Northern Uganda in search for pastures for their animals. This has resulted in tension with the host community of farmers. In recognition of these long-standing conflicts and wishing to contribute to their addressal, in 2021 we set up four focus groups drawing on Indigenous relational practices of conflict resolution. We invoked storytelling and …

“Me Dancing”: An Intrinsic Case Study Of Primary School Boys’ Understandings Of Movement And Dance Through Their Drawings, Rosemary G. Bennett Ms, Jane Southcott

The Qualitative Report

In this research we explore the place of creative embodiment through movement and dance from the understandings of a group of 8-10-year-old elementary school boys. Children can be asked to speak or write about their movement experiences, but for younger cohorts it may easier for them to reveal their ideas via their own drawings. In this qualitative study using drawings as a research method, two classes (a total of 31) of Year 3-4 boys in a suburban elementary school in Melbourne, Australia were asked to produce a drawing of “me dancing” in an empty frame. Each child was then asked …

Critique, Postcritique And Libraries, Mark E. Eaton

Publications and Research

This paper, adopting a perspective from the recent literature of “postcritique”, finds that criticism in librarianship can be constructively supplemented with other methodological approaches. Instead of exclusively using criticism to analyze, dismantle and find fault with texts, librarianship can expand its perspectives to find new reparative possibilities of care. Following the work of Nicholas Holm, Eve Kosofsky Sedgwick, Bruno Latour, Rita Felski and others, we can see that while criticism has thrived as a disposition in librarianship and elsewhere, recent scholarly interventions suggest that it is not the only possible approach. This paper ultimately argues that a postcritical disposition can …

Analytical Characterization Of Artemisinin And Its Derivatives Using High Performance Liquid Chromatography, Electrochemistry Reduction, And Fluorescence, Faraja Ombwayo

Theses and Dissertations

Artemisinin and derivatives were subjected to 37°C and room temperature conditions. When HPLC-UV analysis of both conditions was performed, there were differences in both conditions which suggested that artemisinin and derivatives degrade at 37°C. When artemisinin was electrochemically reduced, new peaks were generated and LC-MS analysis of the reduced artemisinin indicated that either new molecules or molecular reorganization was formed. These electrochemical reduction molecules (products) were deemed analogous to the artemisinin reduction occurring in-vivo after oral administration. Fluorescence analysis of artemisinin and derivatives were performed in the presence of dipyridamole. Dipyridamole intensity was observed to decrease when artemisinin or its …

Mainers Agree Cost Of Everyday Goods Has Increased But Differ On Future Prices 8/25/2025, Unh Survey Center

All UNH Survey Center Polls

A bipartisan majority of Maine residents believe prices on everyday goods have increased over the past year, but Democrats and Independents expect prices to continue to rise while most Republicans expect them to remain flat or decline. Those who expect prices to increase most often blame tariffs. Nearly half of Mainers expect to be worse off financially in a year, with higher costs and poor economic stewardship cited most often as the reason why. Pessimism about the state economy continues to grow, particularly among Independents. Mainers are more optimistic about the national economy than the state economy but a majority …

Probing The Effect Of Peg-Dna Interactions And Buffer Viscosity On Tethered Dna In Shear Flow, Fatema Tuz Zohra, Huda Al-Zuhairi, Jefferson Reinoza, Hyeongjun Kim, Andreas Hanke

Mechanical Engineering Faculty Publications

DNA flow-stretching is a widely employed, powerful technique for investigating the mechanisms of DNA-binding proteins involved in compacting and organizing chromosomal DNA. We combine single-molecule DNA flow-stretching experiments with Brownian dynamics simulations to study the effect of the crowding agent polyethylene glycol (PEG) in these experiments. PEG interacts with DNA by an excluded volume effect, resulting in compaction of single, free DNA molecules in PEG solutions. In addition, PEG increases the viscosity of the buffer solution. By stretching surface-tethered bacteriophage lambda DNA in a flow cell and tracking the positions of a quantum dot labeled at the free DNA end …

Identification, Abundance, And Behavior Of North American Bobcat (Lynx Rufus) Along Road Mitigation Structures Designed For Endangered Species In South Texas, Victoria Hanley, Kevin W. Ryer, Md. Saydur Rahman, John H. Young Jr., Richard J. Kline

School of Integrative Biological & Chemical Sciences Faculty Publications

Endangered species are increasingly used as the target species in implementing and constructing new wildlife crossing structures (WCS). Highways in South Texas fragment the landscape and result in high road mortality for endangered species such as ocelots (Leopardus pardalis, a medium-sized spotted wild cat). In response, the Texas Department of Transportation constructed nine WCS on Farm-to-Market 106 (FM 106), a road which bisects Laguna Atascosa National Wildlife Refuge in Cameron County, Texas. With ocelots being rare and elusive, bobcats (Lynx rufus) are often used as a surrogate species to study felid behavior at road mitigation structures …
