Calibration Of Bbm Parameters Using The Modified State Surface Approach, Xiong Zhang, Beshoy Riad, Eduardo E. Alonso

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The Barcelona Basic Model (BBM) developed by Alonso et al. [1] is the first and the mostwidely used elasto-plastic model for unsaturated soils. The BBM successfully explained many key features of unsaturated soils and received extensive acceptance. However, there is lack of a well-establishedmethod for selecting parameter values for the BBM from laboratory tests, although a variety of methods have been recently developed for calibrating model parameters for the BBM. Concerns still exist on the correctness and robustness of such parameter value selection procedures. The above statements were evidenced by a recent benchmark exercise on selection of parameter values for …

Redesign A Pet Bottle: Creating Possibilities For Future Recycling, Shen Liu

Theses

As a case study, I evaluated the difficulties faced by millennials in recycling PET bottles and their potential expectations for recycling systems. My design includes a visually appealing, compressible PET bottle with a delicate appearance. It helps consumers save four-fifths of their storage space during recycling. That means consumers can easily carry it around until they are ready to recycle. This change is more likely to improve the storage efficiency of bottles and the possibility of bottle recycling. In addition, designing a brand is an important step in building customer trust in sustainable design, helping to connect consumers with their …

Integrating Germplasm Repositories Into Oyster Aquaculture Systems At The Pathway, Center, And Network Levels, Sarah R. Bodenstein

LSU Doctoral Dissertations

Germplasm repositories offer many potential benefits to commercial farm operations, including preserving genetic resources and increasing production capabilities. Aquaculture industries have yet to take advantage of repository storage despite decades of research evaluating cryopreservation protocols. Eastern oysters (Crassostrea virginica), for example, are a useful research species when addressing this problem. Oysters are an economically important aquaculture species and a high-throughput cryopreservation method for oysters already exists. To address the gap between protocol research and commercial application a different approach is necessary that can analyze the requirements of repository development at multiple organizational levels. The goal of this dissertation was to …

A Small Secreted Protein Nicol Regulates Lumicrine-Mediated Sperm Maturation And Male Fertility, Daiji Kiyozumi, Kentaro Shimada, Michael Chalick, Chihiro Emori, Mayo Kodani, Seiya Oura, Taichi Noda, Tsutomu Endo, Martin M Matzuk, Daniel H Wreschner, Masahito Ikawa

Faculty, Staff and Students Publications

The mammalian spermatozoa produced in the testis require functional maturation in the epididymis for their full competence. Epididymal sperm maturation is regulated by lumicrine signalling pathways in which testis-derived secreted signals relocate to the epididymis lumen and promote functional differentiation. However, the detailed mechanisms of lumicrine regulation are unclear. Herein, we demonstrate that a small secreted protein, NELL2-interacting cofactor for lumicrine signalling (NICOL), plays a crucial role in lumicrine signalling in mice. NICOL is expressed in male reproductive organs, including the testis, and forms a complex with the testis-secreted protein NELL2, which is transported transluminally from the testis to the …

Universal Screening For Student Mental Health: Selection Of Norming Sample As A Determinate Of Risk Status, Meagan Zeitvogel

LSU Master's Theses

The prevalence of student mental health concerns has increased the need for universal mental health screening. In turn, students may have increased access to services and support. Some screeners determine risk status by comparing student scores to norming samples that can be based solely on age (i.e., combined-gender) or on age and gender (i.e., separate-gender). Combined-gender norming samples assign risk status based on typical emotional and behavioral functioning across development. Separate-gender norming samples assign risk status based on developmental and biological differences between boys and girls. Currently, there is no research determining if students’ risk status changes based on norming …

Direct Selection Of Dna-Encoded Libraries For Biased Agonists Of Gpcrs On Live Cells, Bo Cai, Amal El Daibani, Yuntian Bai, Tao Che, Casey J Krusemark

2020-Current year OA Pubs

G protein-coupled receptors (GPCRs) are the largest superfamily of human membrane target proteins for approved drugs. GPCR ligands can have a complex array of pharmacological activities. Among these activities, biased agonists have potential to serve as both chemical probes to understand specific aspects of receptor signaling and therapeutic leads with more specific, desired activity. Challenges exist, however, in the development of new biased activators due, in part, to the low throughput of traditional screening approaches. DNA-encoded chemical libraries (DELs) dramatically improve the throughput of drug discovery by allowing a collective selection, rather than discrete screening, of large compound libraries. The …

Rimer, Sarah E. Gale, Raymond Luc, Shay S. Bidani, Carrie A. Sibbald, Angela N. Lewis, Belgacem Mihi, Pranjal Agrawal, Martin Goree, Marlie Maestas, Elise Hu, David F. Peters, Misty Good

2020-Current year OA Pubs

Necrotizing enterocolitis (NEC) is a deadly gastrointestinal disease of premature infants that is associated with an exaggerated inflammatory response, dysbiosis of the gut microbiome, decreased epithelial cell proliferation, and gut barrier disruption. We describe an in vitro model of the human neonatal small intestinal epithelium (Neonatal-Intestine-on-a-Chip) that mimics key features of intestinal physiology. This model utilizes intestinal enteroids grown from surgically harvested intestinal tissue from premature infants and cocultured with human intestinal microvascular endothelial cells within a microfluidic device. We used our Neonatal-Intestine-on-a-Chip to recapitulate NEC pathophysiology by adding infant-derived microbiota. This model, named NEC-on-a-Chip, simulates the predominant features of …

Advances In Mass Spectrometry On Membrane Proteins, Hsin-Chieh Yang, Weikai Li, Jie Sun, Michael L Gross

2020-Current year OA Pubs

Understanding the higher-order structure of membrane proteins (MPs), which are vital for numerous biological processes, is crucial for comprehending their function. Although several biophysical approaches have been used to study the structure of MPs, limitations exist owing to the proteins' dynamic nature and heterogeneity. Mass spectrometry (MS) is emerging as a powerful tool for investigating membrane protein structure and dynamics. Studying MPs using MS, however, must meet several challenges including the lack of stability and solubility of MPs, the complexity of the protein-membrane system, and the difficulty of digestion and detection. To meet these challenges, recent advances in MS have …

2020-Current year OA Pubs

Understanding the serological responses to COVID-19 vaccination in children with history of MIS-C could inform vaccination recommendations. We prospectively enrolled seven children hospitalized with MIS-C and measured SARS-CoV-2 binding IgG antibodies to spike protein variants longitudinally pre- and post-Pfizer-BioNTech BNT162b2 primary series COVID-19 vaccination. We found that SARS-CoV-2 variant cross-reactive IgG antibodies variably waned following acute MIS-C, but were significantly boosted with vaccination and maintained for up to 3 months. We then compared post-vaccination binding, pseudovirus neutralizing, and functional antibody-dependent cell-mediated cytotoxicity (ADCC) titers to the reference strain (Wuhan-hu-1) and Omicron variant (B.1.1.529) among previously healthy children (n = 16) …
