Removal of a Sequestrum in a Horse

A two-year-old American Saddle horse was admitted to the clinic on June 4, 1953, with the following history. During the process of halter breaking, the horse reared up in the stall, broke the halter rope and fell over backwards, striking its head on the cement floor. The following day a swelling was noticed on the back of the head, and the local veterinarian was called. He applied hot packs and later opened the area and removed a small piece of bone. However, abscess drainage continued and the patient was referred to the college clinic showing a fistula in the poll region much like that seen in poll evil

Creating and Evaluating Metadata for a Large Legacy Thesis Collection: From 'Vocational Agriculture' (1922) to 'Microemulsion-mediated syntheses' (2004)

Poster prepared for the TxETDa/USETDA Region 3 Joint Conference and revised for upload into repository.In the summer of 2012, Texas A&M University Libraries uploaded more than 16,000 retrospectively-digitized masters-level theses, dating from 1922 to 2004, into our DSpace institutional repository. Item records for the Retrospective Theses collection were created by mapping existing MARC records, then transforming and enhancing this metadata. Records included fields encoded in our Qualified Dublin Core schema, as well as the custom Thesis schema developed by the TDL member consortium. MODS metadata records were also generated, to be stored as bitstreams

Intention is commitment with expectation

Modal logics with possible worlds semantics can be used to represent mental states such as belief, goal, and intention, allowing one to formally describe the rational behavior of agents. Agent??s beliefs and goals are typically represented in these logics by primitive modal operators. However, the representation of agent??s intentions varies greatly between theories. Some logics characterize intention as a primitive operator, while others define intention in terms of more primitive constructs. Taking the latter approach is a theory due to Philip Cohen and Hector Levesque, under which intentions are a special form of commitment or persistent goal. The theory has motivated theories of speech acts and joint intention and innovative applications in multiagent systems and industrial robotics. However, Munindar Singh shows the theory to have certain logical inconsistencies and permit certain absurd scenarios. This thesis presents a modification of the theory that preserves the desirable aspects of the original while addressing the criticism of Singh. This is achieved by the introduction of an additional operator describing the achievement of expectations, refined assumptions, and new defi- nitions of intention. The modified theory gives a cogent account of the rational balance between agents?? action and deliberation, and suggests the use of meansends reasoning in agent implementations. A rule-based reasoner in Jess facilitates evaluation of the predictiveness and intuitiveness of the theory, and provides a prototypical agent based on the theory

Experimental characterization of thermionic surface cooling in thermionic discharge

In this work, the thermionic cooling effect during thermionic discharges with parallel plate electrodes at 1 Torr is investigated. Time-resolved observation of electron emission and surface temperature is realized in addition to the typical steady state characterization. Surface cooling by the electron emission, initiated by plasma ignition, is directly captured at its onset and an estimated cooling capacity of 1.6 \pm 0.2 MW/m^2 is observed. The present work provides experimental evidence of considerable surface cooling achieved by thermionic cooling. This result indicates that thermionic cooling can be a promising thermal protection method at elevated temperatures, such as those encountered by hypersonic vehicle leading edges in flight.Comment: 14 pages, 21 figures.

Structural, Magnetic and Transport Properties of B-Site Substituted Perovskite La0.7Sr0.3MnO3

In this chapter, in order to understand the structural related magnetic and transport properties of B site substituted perovskites La0.7Sr0.3MnO3 (LSMO), we have systematically investigated the effects of replacing some of the Mn with nonmagnetic elements Ti, Zr, Cu, Al, Zn and magnetic elements Co, Ni, Cr, Fe. The structural, magnetic and electrical phase transitions and transport properties of these compounds were investigated by neutron diffraction, magnetization and electric resistivity measurements

Preparing for a Name Disambiguation Application for Institutional Repositories at Texas A&M University: the Planning and Test Preparation Phases

At Texas A&M University Libraries, a cross-departmental task group was formed to examine possible solutions to the lack of authority control in the Libraries’ institutional repositories. It recommended the development of an app that would utilize internal identifiers and existing ones (ORCID, etc.) to disambiguate the names of persons and other entities. Our presentation will focus on the initial work of the task group in planning the app, and the cleanup of a sample of personal names to prepare for the testing of the future prototype of this app. Finally, we will highlight future steps for our project

Report of the DAMENames Ad Hoc Committee

In early 2018, the DAMEid group requested that Cataloging and Metadata unit examine the metadata needs for the DAME. When analyzing metadata needs in both OAKTrust and Fedora, it became clear that the lack of name authority control was causing serious problems for users, especially in the case of a single author having many entries in the author index. For example, Steven M. Wright, Royce E. Wisenbaker, Professor II in Chemical and Electrical Engineering, has 10 different entries for his name. This problem is caused by the lack of authority control and the inconsistent ways in which names are inputted into Vireo and OAKTrust. In their report to the DAMEid committee, the Metadata and Cataloging librarians strongly suggested that some type of name authority control be implemented within the DAME. In smaller repositories with few names and fewer entities (e.g., persons, organizations, subjects, etc.), the absence of explicit disambiguation or authority control can be a manageable problem. When only a few authors share a name, it is easy to tell them apart based on the subject matter of the works attached to the name. The problem compounds as collections grow larger and the number of entities with the same name that need to be distinguished from each other increases. For example, in the large OAKTrust IR, it is hard for a user to identify the "Steven Wright" that he or she is looking for, as there are several authors so named with dozens of items in the IR. Another issue that emerges in a system with no authority control – such as OAKTrust – is that an everyday typographical error (an extra space, no period after an initial, misspellings, etc.) results in a new entry in the author list. This results in multiple names for one person and it means that there is no way for a user to easily identify all the works attributed to one author

The effect of thermophoresis on the discharge parameters in complex plasma experiments

Thermophoresis is a tool often applied in complex plasma experiments. One of the usual stated benefits over other experimental tools is that changes induced by thermophoresis neither directly depend on, nor directly influence, the plasma parameters. From electronic data, plasma emission profiles in the sheath, and Langmuir probe data in the plasma bulk, we conclude that this assumption does not hold. An important effect on the levitation of dust particles in argon plasma is observed as well. The reason behind the changes in plasma parameters seems to be the change in neutral atom density accompanying the increased gas temperature while running at constant pressure.Comment: 14 pages, 12 figure

Neutron and Magnetic Studies of La₀.₇Sr₀.₃Mn₁₋ₓCrₓO₃(x ≤ 0.7): A Homogeneous Charge-Ordered System

Structural and magnetic properties of La0.7Sr0.3Mn1-xCrxO3 (0 \u3c x ≤ 0.7) have been studied in order to determine the effect of substitution of Cr3+ for Mn3+. The data consist of neutron and x-ray powder-diffraction and magnetization measurements. We previously suggested these systems transition from ferromagnetic to antiferromagnetic ordering with the intermediate concentrations containing coexisting ferromagnetic and antiferromagnetic domains. Upon further detailed examination, we find that the neutron data can be fit using a single homogeneous long-range magnetically ordered state and compositionally dependent charge ordering. The magnetic structures are controlled by the competition between Mn-Mn, Mn-Cr, and Cr-Cr interactions (double exchange and superexchange). The metal to semimetal and semimetal to insulator transitions can be quantitatively described as due to the localization effect of superexchange. The presence of charge ordered states in the insulating region arises from the favorable energetics of Mn4+-O-Cr3+ superexchange bonds relative to Mn3+-O-Cr3+ bonds
