Photochemical water treatment technologies have been extensively studied in recent years to update the current practices and find an innovative, cheap, and sustainable way to treat contaminated water. Despite the well-documented advantages, these technologies faced some challenges and limitations in the way of technology transfer. Among all the challenges, the presence of dissolved organic matter (DOM) poses a serious challenge to the application of these technologies, especially photocatalysis. Moreover, the prospect of utilizing the new technology of light-emitting diodes (LEDs) offers an upgrade in the efficiency of the current practice of ultraviolet (UV) dosing. To understand the effect of DOM …

The Relative Importance Of Wind-Driven And Chimney Effect Cave Ventilation: Observations In Postojna Cave (Slovenia), Lovel Kukuljan, Franci Gabrovsek, Matthew Covington

International Journal of Speleology

Density-driven chimney effect airflow is the most common form of cave ventilation, allowing gas exchange between the outside and the karst subsurface. However, cave ventilation can also be driven by other mechanisms, such as barometric changes or pressure differences induced by the outside winds. We discuss the mechanism and dynamics of wind-driven ventilation using observations in Postojna Cave, Slovenia. We show how seasonal airflow patterns driven by the chimney effect are substantially modified by outside winds. Wind flow over irregular topography forms near-surface air pressure variations and thus pressure differences between cave entrances at different locations. These pressure differences depend …

Zeta Potential Measurements For Surface Modification Of Plastic Substrates For Nanofluidic Biosensors, Qinhan Liu

LSU Master's Theses

Polymeric materials have revealed their great potentials in micro- and nano- fluidic devices for biosensing. Their advantages include low cost, various physicochemical properties, well-developed fabrication, and surface modification protocols comparing with traditional materials such as silicon or glass. Surface modification consists an essential step in fabrication of polymer-based biosensors. A proper characterization is required to justify the effectiveness of modifications on polymer surface. For nanofluidic devices, special phenomena such as overlapped electrical double layer, ion rectification and electroosmosis flow can dominate the behavior of single molcules.

An Artificial Intelligence Tool For Accessible Science Education, Jacob D. Watters, April Hill Dr., Melissa Weinrich Dr., Cary Supalo, Feng Jiang Dr.

Journal of Science Education for Students with Disabilities

One of the most important issues in accessible science education is creating a laboratory workspace accessible to blind students or students with visual impairments (VI). Although these students are often provided access to the science lectures, they are usually denied full participation in hands-on laboratory work. Current solutions to this problem focus on providing special accommodations such as asking sighted lab partners to complete the hands-on work. Although the accessibility of laboratory devices in modern science education has been improved in recent years, students with VI often remain passive learners. In this work, we developed a new artificial intelligence tool, …

Is Women’S Empowerment A Thucydides’ Trap For Patriarchy In Pakistan? The Aurat (Woman) March-2020 And Bina Shah’S Before She Sleeps, Malik Haroon Afzal, Muhamad Rashidi Mohd Pakri, Nurul Farhana Low Abdullah

Journal of International Women's Studies

The Aurat (literal meaning, “woman” in Hindi) March, first organized in Pakistan on International Women’s Day in 2018, fanned the fire of feminist struggle in Pakistan. Since its inception, Pakistan’s patriarchy has tried to supress rising feminist voices. Last year (2020), the effort to supress these voices reached an exceptional level. Feminists faced a storm of opposition in the form of counter-marches and counter-narratives which were motivated mainly by the patriarchal agency of the country. This situation provides the basis for a critical examination of the deeply rooted patriarchal mind set, with reference to the prevailing gender politics of Pakistan. …

A Good Wife Or A Greedy Wife? Women's Roles As Wives In Chinese Corruption News Coverage, Yiyan Li

Journal of International Women's Studies

Xi Jinping, China’s president, has embarked on the largest anti-corruption campaign in modern Chinese history. This study provides insight into the media representing the wife figure in contemporary corruption news in China. To this end, this study employs critical discourse analysis to analyse news articles from the Central Committee for Discipline Inspection (CCDI). The data reveals news articles depict wives of corrupt cadres as greedy if they have participated in their husbands’ corrupt behaviors. In this sense, wives are represented as being responsible for their husbands’ corruption, while the ruling party’s role is marginalized. Thus, this representational strategy allows the …

Faculty and Student Publications

Using data samples of 89.5 and 711 fb-1 recorded at energies of s=10.52 and 10.58 GeV, respectively, with the Belle detector at the KEKB e+e- collider, we report measurements of branching fractions of semileptonic decays Ξc0→Ξ-ℓ+νℓ (ℓ=e or μ) and the CP-asymmetry parameter of Ξc0→Ξ-π+ decay. The branching fractions are measured to be B(Ξc0→Ξ-e+νe)=(1.31±0.04±0.07±0.38)% and B(Ξc0→Ξ-μ+νμ)=(1.27±0.06±0.10±0.37)%, and the decay parameter αΞπ is measured to be 0.63±0.03±0.01 with much improved precision compared with the current world average. The corresponding ratio B(Ξc0→Ξ-e+νe)/B(Ξc0→Ξ-μ+νμ) is 1.03±0.05±0.07, which is consistent with the expectation of lepton flavor universality. The first measured asymmetry parameter ACP=(αΞ-π++αΞ¯+π-)/(αΞ-π+-αΞ¯+π-)=0.024±0.052±0.014 is found …

Extracting Rural Crash Injury And Fatality Patterns Due To Changing Climates In Riti Communities Based On Enhanced Data Analysis And Visualization Tools (Phase I), Guohui Zhang, Panos Prevedouros, David Ma, Hao Yu, Zhenning Li, Runze Yuan

CSET Project Reports

Traffic crashes cause considerable incapacitating injuries and losses in Rural, Isolated, Tribal, or Indigenous (RITI) communities. Compared to urban traffic crashes, those rural crashes, especially for those occurred in RITI communities, are heavily associated with factors such as speeding, low safety devices application (for instance, seatbelt), adverse weather conditions and lacking maintenance and repairers for road conditions, inferior lighting conditions, and so on. Therefore, there exists an urgent need to investigate the unique attributes associated with the RITI traffic crashes based on numerous approaches, such as statistical methods, and data-driven approaches.
