Pasture Management Relevant Behaviour Of Yaks (Bosgrunniens), O. Kaufmann, A. Tolebekova

IGC Proceedings (1977-2023)

After a decline in yak populations in Central Asia, efforts have been made for several years to rebuild them. In that context, the ecological demands of the alpine landscape must be taken into account. The aim of the studies was to analyse the behaviour of yak cows in short time intervals and to deduce which sub-areas the yaks prefer more or less strongly, which altitudes in the mountains the animals visit in the course of a year, which distances they cover in summer and winter and which factors influence their grazing behaviour. The investigations were carried out on yaks in …

Herbage And Livestock Responses For N-Fertilized And Grass-Legume Grazing Systems, D. M. Jaramillo, José C. B. Dubeux Jr., L. M. D. Queiroz, L. Garcia, E. R. S. Santos

IGC Proceedings (1977-2023)

Forage legumes provide an alternative N source in grazing systems. The objective was to evaluate plant and animal responses in N-fertilized or grass-legume-based systems under continuous stocking during winter and summer, from 2016-2019. The three treatments consisted of year-round forage systems including winter and summer forage components. The first system (Grass+N) included N-fertilized (112 kg N ha^-1 yr^-1) ‘Argentine’ bahiagrass (Paspalum notatum) pastures during the summer, overseeded with a mixture (56 kg ha^-1 of each) of ‘FL 401’ cereal rye (Secale cereale) and ‘RAM’ oat (Avena sativa) during winter with …

New Forms Of Pastoral Mobility Among Sheep Herders In The Algerian Steppe; The Case Of Pastoralists Of Djelfa, Dihia Gaci, Jean-Pierre Boutonnet

IGC Proceedings (1977-2023)

The recent socio-economic, political and climatic changes experienced by the Algerian steppe for the last decades have led to profound changes in pastoral mobility practices. This study describes the new mobility practices as currently adopted by the breeders of the Djelfa region. The realization of 59 semi-directive surveys was conducted between 2014 and 2016 among breeders in different reception areas. Practices related to the distance travelled during an annual cycle, the transhumance calendar and itinerary and the passage or not in the homeland are diverse. These practices of mobility can vary from one year to another or during the life …

Using Single Cell Type Proteomics To Identify Al-Induced Proteomes In Outer Layer Cells And Interior Tissues In The Apical Meristem/Cell Division Regions Of Tomato Root-Tips, Jesse Potts, Hui Li, Yaoguo Qin, Xingbo Wu, Dafeng Hui, Kamal Al Nasr, Suping Zhou, Yang Yong, Tara Fish, Jiping Liu, Theodore W. Thannhauser

Biology Faculty Research

Aluminum (Al) toxicity primarily targets the root tips, inhibiting root growth and function and leading to crop yield losses on acidic soils. Previously we reported using laser capture microdissection (LCM) proteomics to identify Al-induced proteins in the outer layer cells in the transitional zone of tomato root-tips. This study aims to further characterize Al-induced proteomic dynamics from the outer to interior tissues, thus providing a panoramic view reflecting Al resistance in the root tip as a whole in tomatoes. Three types of cells were isolated via LCM from the basal 350–400 μm (below cell elongation regions) of root tips using …

Robust Plant Segmentation Of Color Images Based On Image Contrast Optimization, Yuzhen Lu, Sierra N. Young, Haifeng Wang, Nuwan Wijewardane

Civil and Environmental Engineering Faculty Publications

Plant segmentation is a crucial task in computer vision applications for identification/classification and quantification of plant phenotypic features. Robust segmentation of plants is challenged by a variety of factors such as unstructured background, variable illumination, biological variations, and weak plant-background contrast. Existing color indices that are empirically developed in specific applications may not adapt robustly to varying imaging conditions. This study proposes a new method for robust, automatic segmentation of plants from background in color (red-green-blue, RGB) images. This method consists of unconstrained optimization of a linear combination of RGB component images to enhance the contrast between plant and background …

Determination Of Dissociation Constants Of Protein Ligands By Thermal Shift Assay, Jaina A. Bhayani, Miguel Ballicora

Chemistry: Faculty Publications and Other Works

The thermal shift assay (TSA) is a powerful tool used to detect molecular interactions between proteins and ligands. Using temperature as a physical denaturant and an extrinsic fluorescent dye, the TSA tracks protein unfolding. This method precisely determines the midpoint of the unfolding transition (Tm" role="presentation">), which can shift upon the addition of a ligand. Though experimental protocols have been well developed, the thermal shift assay data traditionally yielded qualitative results. Quantitative methods for Kd" role="presentation"> determination relied either on empirical and inaccurate usage of Tm" role="presentation"> or on isothermal approaches, which do not take full advantage of the …

Simple Summary

As of October 2021, over 245 million people have been infected and nearly 5 million have died due to COVID-19. Atherosclerosis is a lipid-driven chronic inflammation of the arterial wall with coronary artery disease (CAD) that may lead to acute coronary syndrome (ACS), which remains the main cause of death in developed countries. We believe that due to CAD development factors affecting the vessel wall, the SARS-CoV-2 infection may precipitate further advancement of future thromboembolic events by a plaque erosion or rupture. Therefore, this metanalysis aims to unambiguously establish the role of the history of CAD in mortality …

Pastoralism, Social, Gender, And Policy Issues, Nahid Naghizadeh

IGC Proceedings (1977-2023)

Nearly half of the Earth's land surface is classified as rangelands. Rangeland's health and productivity are directly critical to the livelihoods, cultures, and resilience of more than 500 million people worldwide, many of whom are indigenous peoples who depend on rangelands. Pastoralism is very diverse; it can be found in all continents, from the drylands of Africa and the Arabian Peninsula to the highlands of Asia and Latin America, or the tundra in the circumpolar zones, and in particular where crop cultivation is physically limited. Pastoralism supports several hundred million households worldwide and manages one billion animals, including camels, cattle, …

Ecological Science Infrastructure For Sustainability Transformations In Rangelands, Brandon T. Bestelmeyer, J. E. Herrick, J. R. Brown, D. M. Browning, B. Densambuu, E. Elias, S. E. Mccord, H. R. Peinetti, S. Spiegal, N. P. Webb, J. C. Williamson

IGC Proceedings (1977-2023)

Sustainability transformations—deliberate and radical shifts in values, governance, and management regimes to achieve sustainability—are needed in rangelands as in other components of the Earth system. We review four concepts comprising an ecological science infrastructure to support such transformations. The foundation is standard measurement of rangeland conditions in the field, especially vegetation and soil properties that underpin the environmental aspects of sustainability. Big data resources, especially gridded spatial datasets produced by models and remote sensing, can be combined with field data and computational approaches to upscale information about rangeland conditions and produce additional indicators of ecosystem functions and services. State and …

Free-Enterprise Farming On Grasslands In Central Nsw, Australia, Des Green, Stuart Green, Ted Wolfe, Jo Richardson, Rob Eccles

IGC Proceedings (1977-2023)

A pathway is described in developing and improving the pastures on family-owned sheep and beef properties at sites near Blayney in central NSW. Initially, the twin approach of sowing perennial grasses, predominantly phalaris (Phalaris aquatica) with subterranean clover (Trifolium subterraneum) plus the recommended addition of superphosphate fertiliser, was closely followed but within a decade ill-thrift in pastures and livestock occurred. Once the core problem of soil acidity was recognised, steps were taken to overcome this constraint with applications of lime. However, an additional modification involving the application of gypsum with lime had to be sorted out …

Guano-Derived Morphologies And Associated Minerals Found In Cova De Sa Guitarreta, Llucmajor, Balearics, Antonio Merino Juncadella, Joan J. Fornós, Antoni Mulet, Joaquín Ginés

International Journal of Speleology

Cova de sa Guitarreta is located in the southern part of Mallorca Island (western Mediterranean). It was formed presumably by hypogenic processes in Upper Miocene reefal calcarenites. The cave hosts an important breeding colony of bats during the end of spring and early summer. Its microclimate is influenced by the presence of a thermal phreatic water table (27.7ºC) as well as by bat populations remaining in the cave along the reproductive season. The morphological bat-related features include bat claws and thumb marks scratches, together with several morphologies linked to bat excreta and aggressive leachates from guano. From the mineralogical point …

Water Insecurity, Water Borrowing, And Psychosocial Stress Among Daasanach Pastoralists In Northern Kenya, Leslie Ford, Hilary J. Bethancourt, Zane Swanson, Rosemary Nzunza, Amber Wutich, Alexandra Brewis, Sera Young, David Almeida, Matthew J. Douglass, Emmanuel K. Ndiema, David R. Braun, Herman Pontzer, Asher Y. Rosinger

School of Natural Resources: Faculty Publications

This article quantifies Daasanach water insecurity experiences in Northern Kenya, examines how water insecurity is associated with water borrowing and psychosocial stress, and evaluates if water borrowing mitigates the stress from water insecurity. Of 133 households interviewed in 7 communities, 95% were water insecure and 74.4% borrowed water three or more times in the prior month. Regression analyses demonstrate water borrowing frequency moderates the relationship between water insecurity and psychosocial stress. Only those who rarely or never borrowed water reported greater stress with higher water insecurity. The coping mechanism of water borrowing may help blunt water insecurity-related stress.

Blood Flow Restriction Training After Patellar Instability (Brains Trial), Benjamin D. Brightwell, Austin V. Stone, Xiaojuan Li, Peter A. Hardy, Katherine L. Thompson, Brian W. Noehren, Cale A. Jacobs

Orthopaedic Surgery and Sports Medicine Faculty Publications

Background

Patellar instability is a common and understudied condition that disproportionally affects athletes and military personnel. The rate of post-traumatic osteoarthritis that develops following a patellar dislocation can be up to 50% of individuals 5–15 years after injury. Conservative treatment is the standard of care for patellar instability however, there are no evidence-informed rehabilitation guidelines in the scientific literature. The purpose of this study is to assess the effectiveness of blood-flow restriction training (BFRT) for patellar instability. Our hypotheses are that this strategy will improve patient-reported outcomes and accelerate restoration of symmetric strength and knee biomechanics necessary to safely return …

Long-Lasting Impairments In Quadriceps Mitochondrial Health, Muscle Size, And Phenotypic Composition Are Present After Non-Invasive Anterior Cruciate Ligament Injury, Steven M. Davi, Ahram Ahn, Mckenzie S. White, Timothy A. Butterfield, Kate Kosmac, Oh Sung Kwon, Lindsey K. Lepley

Center for Muscle Biology Faculty Publications

Introduction: Despite rigorous rehabilitation aimed at restoring muscle health, anterior cruciate ligament (ACL) injury is often hallmarked by significant long-term quadriceps muscle weakness. Derangements in mitochondrial function are a common feature of various atrophying conditions, yet it is unclear to what extent mitochondria are involved in the detrimental sequela of quadriceps dysfunction after ACL injury. Using a preclinical, non-invasive ACL injury rodent model, our objective was to explore the direct effect of an isolated ACL injury on mitochondrial function, muscle atrophy, and muscle phenotypic transitions.

Methods: A total of 40 male and female, Long Evans rats (16-week-old) were exposed to …

Performance Study On Extractive Text Summarization Using Bert Models, Shehab Abdel-Salam, Ahmed Rafea

Faculty Journal Articles

The task of summarization can be categorized into two methods, extractive and abstractive. Extractive summarization selects the salient sentences from the original document to form a summary while abstractive summarization interprets the original document and generates the summary in its own words. The task of generating a summary, whether extractive or abstractive, has been studied with different approaches in the literature, including statistical-, graph-, and deep learning-based approaches. Deep learning has achieved promising performances in comparison to the classical approaches, and with the advancement of different neural architectures such as the attention network (commonly known as the transformer), there are …

Journal of Electrochemistry

Three-dimensional (3D) nanostructural Flower-like cobalt sulfide (CoS) on flexible self-supporting graphene tape electrode (GTE) with remarkably electrocatalytic activity toward glucose was successfully prepared by electrodeposition. Structural characterizations revealed that the electrodeposited CoS was highly dispersed on GTE as an active material. The fabricated binder-free and self-standing CoS/GTE shows a good linear response in the range of 0.025 ~ 1.0 mmol·L^-1, reaching a high glucose sensitivity value of 323.3 μA·(mmol·L ^-1)^-1·cm^-2 and a low detection limit of 8.5 μmol·L ^-1 (S/N = 3). Moreover, the as-prepared sensor was well applied for glucose …

Lights, Camera, Action: A Focus Group Study Exploring University Students' Experiences Of Learning Via Zoom, Bill J. Garris, Bethany Novotny, Kwangman Ko

ETSU Faculty Works

In response to the global Covid-19 pandemic, universities across the world moved coursework online and frequently used Zoom videotelephony software to replicate the experience of learning in a classroom. While this platform supported certain aspects of the traditional classroom, such as immediacy of responses and the facilitation of social interactions, learning via Zoom also differed in various ways from the familiar classroom experience. Although there has been considerable research on online learning, most studies focused on an asynchronous design and interaction. Thus, the understanding of learning within synchronous, video-mediated platforms, such as Zoom, is nascent. In this study, the data …

Bottom-Up Drivers Of Future Fire Regimes In Western Boreal North America, Adrianna C. Foster, Jacquelyn K. Shuman, Brendan M. Rogers, Xanthe J. Walker, Michelle C. Mack, Laura L. Bourgeau-Chavez, Sander Veraverbeke, Scott J. Goetz

Aspen Bibliography

Forest characteristics, structure, and dynamics within the North American boreal region are heavily influenced by wildfire intensity, severity, and frequency. Increasing temperatures are likely to result in drier conditions and longer fire seasons, potentially leading to more intense and frequent fires. However, an increase in deciduous forest cover is also predicted across the region, potentially decreasing flammability. In this study, we use an individual tree-based forest model to test bottom-up (i.e. fuels) vs top-down (i.e. climate) controls on fire activity and project future forest and wildfire dynamics. The University of Virginia Forest Model Enhanced is an individual tree-based forest model …
