    In 2008, Pierce's disease was discovered in Oklahoma in a backyard garden. Limited research regarding Pierce's disease has been done to monitor the disease throughout the state. In 2008-2009 and in 2016-2017, two surveys were conducted based on suspect grape samples being submitted to the diagnostic lab for verification of the bacterium causing Pierce's disease, Xylella fastidiosa. With the disease being relatively new to the state, it is important to monitor knowledge of the disease among growers, as well as presence. This research was done using a questionnaire that was distributed via email link to n=63 producers. There was n=18 complete responses from 14 Oklahoma counties that could be analyzed. Although there were no new counties to report having Pierce's disease, analysis showed Oklahoma grape producers need more education regarding integrated pest management practices (IPM) and insect vector identification. It is important to note, there could be more vineyards that have the disease, but since producers' do not know how to identify symptoms, damage and vectors it is going undetected. The findings of this survey help determine Oklahoma grape producers' knowledge of Pierce's disease, ability to identify Pierce's disease, and ability to identify insect vectors for Pierce's disease. In addition, the purpose was to understand Oklahoma grape producers' knowledge and use of integrated pest management techniques

    Multimodal, Multidimensional Models of Mouse Brain

    Naturally occurring mutants and genetically manipulated strains of mice are widely used to model a variety of human diseases. Atlases are an invaluable aid in understanding the impact of such manipulations by providing a standard for comparison and to facilitate the integration of anatomic, genetic, and physiologic observations from multiple subjects and experiments. We have developed digital atlases of the C57BL/6J mouse brain (adult and neonate) as comprehensive frameworks for storing and accessing the myriad types of information about the mouse brain. Along with raw and annotated images, these contain database management systems and a set of tools for comparing information from different techniques and different animals. Each atlas establishes a canonical representation of the mouse brain and provides the tools for the manipulation and analysis of new data. We describe both these atlases and discuss how they may be put to use in organizing and analyzing data from mouse models of epilepsy

    Writing in Secondary (WiS) Academic Partners is a partnership between the New South Wales Department of Education and the Centre for Educational Research, School of Education, Western Sydney University (WSU). The WiS project was undertaken across secondary schools (n=20) within NSW in 2021 and 2022. The project focused on the improvement in academic writing for Stages 4 and 5 within History; Personal Development, Health and Physical Education; Science and Visual Arts. The impact of WiS on students' writing within these subjects and teachers' pedagogical changes in the teaching of writing are identified in this report

    Interaction between vortices in models with two order parameters

    Get PDF
    The interaction energy and force between widely separated strings is analyzed in a field theory having applications to superconducting cosmic strings, the SO(5) model of high-temperature superconductivity, and solitons in nonlinear optics. The field theory has two order parameters, one of which is broken in the vacuum (giving rise to strings), the other of which is unbroken in the vacuum but which could nonetheless be broken in the core of the string. If this does occur, there is an effect on the energetics of widely separated strings. This effect is important if the length scale of this second order parameter is longer than that of the other fields in the problem.Comment: 11 pages, 3 figures. Minor changes in the text.

    Elucidating the crystal-chemistry of Jbel Rhassoul stevensite (Morocco) by advanced analytical techniques

    The composition of Rhassoul clay is controversial regarding the nature of the puremineral clay fraction which is claimed to be stevensite rather than saponite. In this study, the raw and mineral fractions were characterized using various techniques including Fourier transform infrared spectroscopy and magic angle spinning nuclear magnetic resonance (MAS NMR). The isolated fine clay mineral fraction contained a larger amount of Al (>1 wt.%) than that reported for other stevensite occurrences. The 27Al MAS NMR technique confirmed that the mineral is stevensite in which the Al is equally split between the tetrahedral and octahedral coordination sites. The 29Si NMR spectrum showed a single unresolved resonance indicating little or no short-range ordering of silicon. The chemical composition of the stevensite from Jbel Rhassoul was determined to be ((Na0.25K0.20 (Mg5.04Al0.37Fe0.20&0.21)5.61(Si7.76Al0.24)8O20(OH)4). This formula differs from previous compositions described from this locality and shows it to be an Al-bearing lacustrine clay mineral

    Disparities in Women With Endometriosis Regarding Access to Care, Diagnosis, Treatment, and Management in the United States: A Scoping Review.

    Endometriosis is a benign gynecological condition that elicits chronic pain in 2-10% of reproductive-age women in the United States and exists in approximately 50% of women with infertility. It creates complications such as hemorrhage and uterine rupture. Historically, the gynecologic symptoms of endometriosis have been associated with economic strain and inferior quality of life. It is suspected that endometriosis diagnosis and treatment are affected by health disparities throughout gynecological care. The goal of this review was to collate and report the current evidence on potential healthcare disparities related to endometriosis diagnosis, treatment, and care across race, ethnicity, and socioeconomic status. This scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and searched the Excerpta Medica Database (EMBASE), Medline Ovid, Cumulated Index to Nursing and Allied Health Literature (CINAHL), Web of Science, and PsycInfo databases for relevant articles on the topic. Eligibility was establishe

    Gray matter atrophy observed by brain MRI is an important correlate to clinical disability and disease duration in multiple sclerosis. The objective of this study was to link brain atrophy visualized by neuroimaging to its underlying neuropathology using the MS model, experimental autoimmune encephalomyelitis (EAE). Volumetric changes in brains of EAE mice, as well as matched healthy normal controls, were quantified by collecting post-mortem high-resolution T2-weighted magnetic resonance microscopy and actively stained magnetic resonance histology images. Anatomical delineations demonstrated a significant decrease in the volume of the whole cerebellum, cerebellar cortex, and molecular layer of the cerebellar cortex in EAE as compared to normal controls. The pro-apoptotic marker caspase-3 was detected in Purkinje cells and a significant decrease in Purkinje cell number was found in EAE. Cross modality and temporal correlations revealed a significant association between Purkinje cell loss on neuropathology and atrophy of the molecular layer of the cerebellar cortex by neuroimaging. These results demonstrate the power of using combined population atlasing and neuropathology approaches to discern novel insights underlying gray matter atrophy in animal models of neurodegenerative disease
