Commercial Laying Hen Farms' General Characteristics, Environmental Management, And Biosecurity Practices In The Sub-Arid Area Of Algeria, Yacine Kasmi, Nouzha Heleili, Zohra Ahmed Gaid, Brahim Hamad, Leyla Hadef, Manel Merradi

The Thai Journal of Veterinary Medicine

The success of commercial laying hen farms depends on the possibility of managing environmental conditions properly and performing strict biosecurity measures, which would increase productivity, enhance the performance of the flock, and save money, especially in regions characterized by challenging climatic conditions, such as the sub-arid and arid areas. There is, however, very little literature exploring these issues in the Algerian context. The objective of the study was to assess environmental management and biosecurity practices, and the relationship between these and farm size in the Algerian sub-arid area (northeast Algeria). The face-to-face interviews were conducted between January 2024 and April …

Durability Performance Of Sustainable Fly Ash-Based Geopolymer Concrete Incorporating Waste Glass, El-Said Abdelsalam Maaty, Mariam Farouk Ghazy, Mohamed Gamal Eldmarny

Mansoura Engineering Journal

The cement and concrete industries contribute significantly to environmental degradation through high CO₂ emissions and extensive resource consumption. Cement manufacturing accounts for nearly 8% of global CO₂ emissions, primarily from limestone calcination, while raw material extraction leads to resource depletion and ecological disruption. Increasing attention is being directed toward the use of recycled glass as an eco-friendly substitute in geopolymer concrete, offering a sustainable solution to existing challenges. This study investigates the effectiveness of replacing fly ash with waste glass powder (WGP) at 0%, 10%, 20%, and 30%, and substituting natural sand with waste glass sand (WGS) at 0%, 15%, …

Untargeted Metabolomics Reveals Organ-Specific And Extraction-Dependent Metabolite Profiles In Endemic Tajik Species Ferula Violacea Korovin, Sylhiya Mavlonazarova, Kenneth Acosta, Rinat Abzalimov, Saidbeg Satorov, Vyacheslav Dushenkov

Publications and Research

Ferula violacea Korovin, an endemic Tajikistani plant with purported medicinal properties, remains understudied. This study employs untargeted metabolomics to characterize the metabolite profiles of ethanol extracts and juices from F. violacea roots and seeds. In total, 540 distinct metabolites are putatively identified, 419 of which are previously unreported in the Ferula genus, representing a substantial expansion of its known chemical diversity. The most abundant metabolites are terpenoids, amino acid derivatives, and alkaloids. A particularly abundant group of daucane sesquiterpenoids, sharing a common (6-methyl-azulen-4-yl) cyclohexanecarboxylate substructure, is identified, including known metabolites such as ferutidin and ferutinin. Comparative analysis reveals organ-specific metabolic …

Native Bee Assemblages In Prescribed Fire-Managed Prairies: A Case Study From Arkansas, United States, Coleman Z. Little, Neelendra K. Joshi

Entomology and Plant Pathology Faculty Publications and Presentations

Native bee communities in Arkansas remain poorly documented, particularly within fire-managed prairie ecosystems that provide critical habitat for pollinators. This study surveyed bee assemblages at two native prairie remnants in the Arkansas River Valley, one large (Cherokee Prairie Natural Area, CPNA) and one small urban fragment (Jewel Moore Nature Reserve, JMNR), both managed using prescribed fire. Using pan trapping, we recorded 599 individuals representing 96 species across 25 genera, including 49% singletons. Despite differences in size and landscape context, both prairies supported similarly rich bee communities per sample day, with JMNR and CPNA averaging 16.1 and 13.75 species, respectively. However, …

Khsrp-Mediated Decay Of Axonally Localized Prenyl-Cdc42 Mrna Slow Nerve Regeneration, Matthew D. Zdradzinski, Lauren S. Vaughn, Samaneh Matoo, Kayleigh Trumbull, Terika P. Smith, Davis Noblitt, Courtney N. Buchanan, Ashley Loomis, Elizabeth Thames, Seung Joon Lee, Nora Perrone-Bizzozero, Qun Lu, Jessica M. Larsen, Jeffery L. Twiss

Faculty Publications

The small GTPase CDC42 promotes axon growth through actin filament polymerization and this growth is driven by axonal localization of the mRNA encoding the prenylated CDC42 isoform (Prenyl-Cdc42). Here, we show that axonal Prenyl-Cdc42 mRNA levels and the mRNA’s translation are decreased by growth-inhibiting stimulation and increased by growth-promoting stimulation. In contrast, axonal RhoA mRNA transport and translation are increased by growth-inhibiting but unaffected by growth-promoting stimuli. Localized increase in KHSRP in response to growth inhibitory stimulation, through elevation of intracellular Ca²⁺, promotes decrease in axonal levels of Prenyl-Cdc42 mRNA. Distinct 3’UTR motifs regulate transport and …

Dissolved Organic Matter Composition Differs Across Water Types In Mid-Atlantic And Great Lakes Coastal Regions, Jesse Alan Roebuck, Allison N. Myers-Pigg, Peter Regier, Nicholas D. Ward, Matthew J. Cooper, Kenneth M. Kemner, Amy Marcarelli, Elizabeth C. Minor, Michael Philben, Bongkeun Song, Rodrigo Vargas, Jianqiu Zheng

Michigan Tech Publications

Dissolved organic matter (DOM) in coastal surface waters influences local water quality and is an important component of biogeochemical cycling in coastal systems. Many studies have highlighted transformations of DOM along longitudinal river to estuary transects; however, processes that alter DOM composition along lower reaches of rivers and nearshore estuarine waters is poorly understood. The high productivity of coastal environments and their limited representation in Earth System Models further highlights a need for better understanding of DOM transformations along coastal reaches. We leverage a spatially distributed community sampling effort that spans coastal ecosystems across two regions to identify broad spatial …

Paintings Analysis Using Copilot Ai: The Case Of Winston Churchill And Art In His Life, Yuri Zagvazdin

Learning and Educational Center Virtual Teaching and Learning Conference

The objective of this presentation is to demonstrate a method for analyzing artistic style and its potential evolution using the Copilot AI platform. As a case study, I explore the paintings of Winston Churchill (1874–1965), the British Prime Minister, who was also a passionate and prolific painter. Although Churchill began painting in his forties, he produced over 500 works, with his final piece completed in 1962.

Churchill frequently painted scenes from Southern France and Morocco—locations he returned to repeatedly throughout his artistic life. Remarkably, he continued painting even after suffering multiple cerebrovascular accidents. Stroke-induced brain damage is typically detrimental to …

Screening Of Potential Plant Growth‐Promoting Rhizobacteria (Pgpr)-Assisted Phytoremediation To Mitigate Lead Toxicity In Uae Soils, Zeinab A. Mohamed

Thesis/ Dissertation Defenses

Plant growth-promoting actinobacteria can enhance plant resilience to heavy metal contamination. This study evaluated the effects of 1-aminocyclopropane-1-carboxylate deaminase (ACCD)-producing rhizosphere-competent (RC) and non-rhizosphere-competent (NRC) actinobacterial strains on corn growth and lead (Pb) tolerance. A greenhouse experiment was conducted under Pb stress [1000 mg/kg soil as Pb(NO₃)₂] to compare the two isolates. Inoculated plants performed better than uninoculated controls, particularly in non-contaminated soils. Under Pb stress, the isolates #22 (NRC) and #30 (RC) significantly enhanced plant height, dry weight, and chlorophyll content, with RC isolate #30 exhibiting the most pronounced effects. Identified as Streptomyces mirabilis UAE2, isolate #30 reduced electrolyte …

Isolation And Characterization Of Plant Growth Promoting Rhizobacteria From Soils In The Uae And Their Effect On Plant Salt Tolerance, Layla Zayed Almazrouei

Thesis/ Dissertation Defenses

Plants are constantly challenged by environmental stresses that restrict their growth and productivity. In the United Arab Emirates (UAE), soil salinity is a critical barrier to agriculture, particularly for tomato (Solanum lycopersicum), which is highly sensitive to moderate salinity levels (>2.5 dS m⁻¹). This study explored the potential of plant growth–promoting rhizobacteria (PGPR), especially actinobacteria, to enhance salt tolerance in tomato. The objective was to evaluate the effeccts of rhizosphere-competent (RC) and non-rhizosphere-competent (NRC) PGPR on plant physiology and yield in saline sandy soils. Actinobacterial strains were isolated from the tomato rhizosphere were screened for the production of 1-aminocyclopropane-1-carboxylic …
