Arizona Native Plant Seedling Identification Pocket Guide
No full textThis guide is meant to assist in the identification of a few of Arizona’s most common native grasses and forbs. Identifying plants can be hard, identifying seedlings can be outrageously difficult. Here, we attempt to provide general guidelines for seedling identification in the field, in the garden, or in the greenhouse. The species in this guide are just a small fraction of all of the native plants in Arizona. They were chosen for inclusion due to their general common distribution across the state and their high frequency of use in ecological restoration projects. To confirm your identification, take a picture of your plant and ask a Master Gardener for assistance, or wait until the plant grows. Never pick a native (or unknown) plant from the ground. Measurements for this guide were taken inside of a greenhouse and environmental conditions can modify aspects of growth, so all values are provided as a suggested guide
Computational Approach to Wingtip Jets Effect on Flow Entrainment and Aerodynamics
No full textThis work presents computation analysis of the dynamics of a wing with blowing jets at the wingtip. Specifically, the project uses a NACA 0012 wing model, with internal flow chambers and blowing jet slits at the wingtip. With this wing setup, the project was a sensitivity investigation to the impact of different Computational Fluid Dynamic setup conditions and meshes across a range of different freestream velocities and jet pressures. This computational study complements an experimental investigation of the same NACA 0012 with wingtip jets. A comparison of the experimental and computational results are discussed, with a focus on the similarities and differences. The study found the impact of blowing jets, either from the top or bottom jet, had positive effects to coefficient of lift by artificially extending out the wings aspect ratio, and interrupting the formation of wingtip vortices. It was also observed that the inclusion of jets has a more significant impact at lower freestream velocities, where the difference between jet pressure and freestream velocity is larger. Lastly, these results can be correlated back to the experimental data, giving credence to the benefits of wingtip jets. The results will discuss these findings in more detail, assessing the impact of freestream velocity, jet velocity, solver, turbulence model, mesh, and whether the top, bottom, or no jet was active
Measuring Pulse Degradation in Noble Liquid Calorimeters at High Ionization Rates
No full textThe ATLAS detector, located at the CERN laboratory in Geneva, Switzerland, is one of two “discovery experiments” at the energy frontier of particle physics. It is composed of a set of detector elements which measure the products of the proton-proton collisions happening in the center of the ATLAS detector. The colliding protons are provided by CERN’s accelerator complex, the chief accelerator being the Large Hadron Collider (LHC). The LHC is preparing for an upgrade which will increase the rate of collisions taking place at the center of the ATLAS detector by almost an order of magnitude. This will force parts of the detector to operate outside their design specifications. The operation of the ATLAS Liquid Argon Forward Calorimeter (FCal), the part of the ATLASdetector which experiences the highest amount of radiation, will be particularly affected by the increased rate of collisions. The high-radiation environment will cause the FCal electrodes to enter a space-charge limited regime where positive argon ions build up in the liquid argon gap, causing the energy signal measured by the FCal electronics to be degraded in amplitude and distorted in shape. This signal must be corrected in order for FCal data to be useful in future operation of the ATLAS detector. We have designed and constructed an experiment to investigate this problem by using a strong beta emitter sealed inside an FCal electrode to artificially induce positive argon ion buildup in the liquid argon gap. We replicated the high energy events in ATLAS that the calorimeter is designed to study by using a 180-GeV positron test beam to create electromagnetic particle showers in the liquid argon, each of which generated large ionization pulses in the FCal electrode. We compared the degraded and distorted signals from the artificially irradiated FCal electrode with normal signals from a control FCal electrode. We measured and analyzed each of the signal pulses and used the results to characterize the space-charge effect, which will enable the development of software corrections that can be applied to the distorted pulses in order to recover as much of the undistorted energy signal as possible. These types of corrections can be applied in a broader sense to the ATLAS liquid argon calorimeters in order to extend their life as the collision rate at the LHC increases
Small Mammals Along Elevational Gradients & Ground-Dwelling Arthropods Along Red Squirrel Midden Residency Gradients, Pinaleño Mountains, Arizona
No full textEcosystem stability is important for threatened biomes such as the Madrean Archipelago that harbor endemic species of conservation concern. Small mammals play key ecological roles that influence ecosystem function (e.g. homeostasis, or how ecosystem structure remains constant in response to disturbances), yet knowledge of their distributions and interactions is lacking in the region. In my first study, I documented richness and abundance patterns of small mammals along an elevation gradient in the Pinaleño Mountains, the most prominent mountain range of the Madrean Archipelago. I found that species richness peaked in the semi-desert grassland and mixed conifer life zones, but the life zone with the greatest abundance varied seasonally. The study provides insight into factors influencing elevational distributions and serves as a baseline to incorporate monitoring of small mammals as indicators of environmental change. My second study investigated how endangered Mt. Graham red squirrel (Tamiasciurus fremonti grahamensis) middens (cone scale piles where squirrels larderhoard food) influenced the community of ground-dwelling arthropods across a gradient of residency history. I found that middens that had longer squirrel residencies (squirrels residing at and maintaining the midden for longer time periods) were associated with more arthropods compared to lower residency middens. However, the diversity of ground-dwelling arthropods relative to squirrel residency history depended on the diversity metric used. Monitoring of arthropod communities within middens can provide a novel method to assess temporal changes in squirrel food-caching strategies and evaluate forest management actions that may influence midden conditions. Collectively, studying small mammal interactions across diverse gradients can identify new ways of seeing and responding to disturbances that the region may experience in the future
Nine Common Reasons Your Hens Aren't Laying
No full textReduced egg production often reflects normal biological stages, health conditions, or environmental stressors rather than a single isolated problem. Understanding these influences helps flock owners assess age, nutrition, lighting, housing conditions, and overall hen health before assuming a more serious issue. With this knowledge, small-scale producers can make informed management adjustments to support consistent laying and improve overall flock well-being

Geologic Map of the Imperial Reservoir Quadrangle, Yuma County, Arizona and Imperial County, California v. 2.0
No full textGeologic Map of the Imperial Reservoir Quadrangle, Yuma County, Arizona, and Imperial County, California, Scale 1:24,000. The report is part of a digital republication of a 1992 geologic map originally created by the Arizona Geological Survey with financial support from the U.S. Geological Survey. Preparation for republication was conducted by students from the University of Arizona with financial support from the National Geological and Geophysical Data Preservation Program, award number G24AP00258 and included the production of a new GIS geodatabase and a revised map layout. The following text report has not been altered and remains identical to the 1992 original, but there may be situations where unit names, ages, symbology, or other geologic information contained within this report do not match the information presented in the new map layout of the GIS geodatabase.Documents in the AZGS Documents Repository collection are made available by the Arizona Geological Survey (AZGS) and the University Libraries at the University of Arizona.
