Virtual reality (VR) technology provides a human-computer interface that allows participants to interact naturally with digital objects which are represented as three-dimensional images that occupy positions in a three-dimensional world. Related to problems of engineering design and manufacturing, this new technology offers engineers the ability to work with computer models in a three-dimensional, immersive environment. This paper describes a virtual reality application where the results of a discrete event simulation of a manufacturing cell are integrated with a virtual model of the cell to produce a virtual environment. The program described in this paper, the VRFactory, combines results from a commercial discrete event simulation program, SLAM II, with a virtual environment. This allows the user to investigate, using threedimensional computer models, how various changes to the manufacturing cell affect part production. This investigation is performed while immersed in a computer-generated three-dimensional representation of the cell. Existing discrete event programming software allows only two-dimensional views of the factory as the parts progress through the simulation. Parts are shown only as primitive geometric shapes on the computer monitor and instantaneously move from one station to the next. The virtual environment implementation of the SLAM II results allows users to experience the simulation in a fully immersive three-dimensional digital environment. The virtual environment used here is a CAVE™-like projection screen-based facility called the C2, which is located at Iowa State University. This paper describes the creation of the VR model of the manufacturing cell, the animation of the environment and the implementation of the results of the discrete event simulation.

Ranges for CBC data were often very wide, influenced by preanalytic and analytic factors. Hemogregarine infection is associated with a decreased PCV, suggesting that some hemogregarine species are pathogenic in this population.

Given the move toward competency-based veterinary education and the subsequent reevaluation of veterinary curricula, there is a need for specialties to provide guidance to veterinary college administrators and educators on the core knowledge and skills pertaining to their specialty to ensure their inclusion in revised or redesigned curricula. The American Society for Veterinary Clinical Pathology (ASVCP) Education Committee sought to create a list of competencies specific to clinical pathology expected of graduating veterinarians. The stimulus for this project was the American Veterinary Medical Association Council on Education Standards of Accreditation for Colleges of Veterinary Medicine, further driven by the 2018 publication of the Association of American Veterinary Medical Colleges Competency-Based Veterinary Education Working Group framework. The recommendations made in this document are the culmination of the 2016 ASVCP Education Forum for Discussion, multiple remote subcommittee communications, and feedback obtained from ASVCP membership. The final framework includes 8 clinical pathology–focused domains of competence with 20 clinical pathology competencies and 61 clinical pathology illustrative sub-competencies. The clinical pathology–focused domains of competence are: the pre-analytical phase of testing, laboratory medicine and instrumentation, principles of test selection and interpretation, hematology and hemostasis, chemistry, endocrinology, urinalysis, and cytology. These are not intended to replace the nine established AAVMC domains of competence with supportive competencies and illustrative sub-competencies but to guide institutions for how clinical pathology aligns within the competency-based veterinary education (CBVE) framework for the practice-ready veterinary graduate. This clinical pathology competency framework may prove useful and empowering during discussions of curriculum revisions and redesigns.
Feline basal cell carcinomas generally have a benign biological behaviour with a low metastatic rate, and little contemporary information exists regarding potential metastatic behaviour. The purpose of this report is to describe the protracted clinical course of metastatic basal cell carcinoma in a 10‐year‐old female spayed Persian cat affecting the right pelvic limb with nodal metastasis at the time of diagnosis and eventual metastasis to the lungs, lumbar spine, and skin 14 months after initial diagnosis. This report serves as a reminder that these tumours can metastasize and reviews information from human literature that may be helpful in understanding the metastatic pattern, treatment, and prognosis of basal cell carcinoma in veterinary medicine.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
