Coccidia (Apicomplexa: Eimeriidae) of Three-toed Box Turtles, Terrapene carolina triunguis (Reptilia: Testudines), from Arkansas and Oklahoma

We collected 50 three-toed box turtles (Terrapene carolina triunguis) from 9 counties of Arkansas and 4 counties of Oklahoma, and examined their feces for coccidial parasites. Nine of 24 (38%) turtles from Arkansas and 8 of 26 (31%) from Oklahoma were found to be passing oocysts of Eimeria ornata. This represents two new geographic distributional records for this coccidian. Measurements of individual isolates of E. ornate as well as morphological characteristics are provided with comparison to its original description and to another Terrapene coccidian, Eimeria carri. In addition, we noted an adelid pseudoparasite being passed by a single T. c. triunguis from Oklahoma that likely represents a parasite of arthropods

ALCOHOL- AND DRUG-RELATED CONTENTS IN THE NURSING PROGRAM AT ESPÍRITO SANTO FEDERAL UNIVERSITY: A CRITICAL ANALYSIS

The study was based on the project sponsored by the Organization of American States which wasdeveloped by São Paulo Federal University College of Nursing aiming at analyzing the alcohol- and drug-relatedcourse contents taught in undergraduate nursing programs in Brazil. Its purpose was to evaluate teachingconditions concerning this theme in the undergraduate nursing program at Espírito Santo Federal Universitythrough a descriptive survey applied to 86 nursing students. To 95% of the students, the problem related to theconsumption of alcohol and drugs is a theme of great interest. The inclusion of these themes in nursing programsis a facilitating condition for the education of nurses in this area

Vertebrate Natural History Notes from Arkansas, 2017

Because meaningful observations of natural history are not always part of larger studies, important pieces of information often are unreported. Small details, however, can fills gaps in understanding and also lead to interesting questions about ecological relationships or environmental change. We have compiled recent observations of foods, reproduction, record size, parasites, and distribution of 30 species of fishes, new records of distribution and parasites of 2 species of amphibians, and new records of distribution, parasites, reproduction and anomalies of 11 species of mammals

Additional Vertebrate Records and Natural History Notes from Arkansas

Although vertebrates are a commonly studied group of animals, the distribution and natural history of many species within Arkansas is still not well understood or documented. However, recently several new distribution and natural history notes have been published in a continuing series regarding Arkansas’s vertebrates (e.g. Tumlison and Robison 2010; Connior et al. 2011, Connior et al. 2012). Thus, we continue to augment current literature with new records of distribution and provide notes on the natural history of selected vertebrates from Arkansas. All voucher specimens (physical or photographic) are deposited in the vertebrate collections at either Arkansas State University (ASUMZ), Henderson State University (HSU), or South Arkansas University (SAU)

Time evolution and observables in constrained systems

The discussion is limited to first-class parametrized systems, where the definition of time evolution and observables is not trivial, and to finite dimensional systems in order that technicalities do not obscure the conceptual framework. The existence of reasonable true, or physical, degrees of freedom is rigorously defined and called {\em local reducibility}. A proof is given that any locally reducible system admits a complete set of perennials. For locally reducible systems, the most general construction of time evolution in the Schroedinger and Heisenberg form that uses only geometry of the phase space is described. The time shifts are not required to be 1symmetries. A relation between perennials and observables of the Schroedinger or Heisenberg type results: such observables can be identified with certain classes of perennials and the structure of the classes depends on the time evolution. The time evolution between two non-global transversal surfaces is studied. The problem is posed and solved within the framework of the ordinary quantum mechanics. The resulting non-unitarity is different from that known in the field theory (Hawking effect): state norms need not be preserved so that the system can be lost during the evolution of this kind.Comment: 31 pages, Latex fil
