    2013-08-01

    In 2013 the World Association for the Advancement of Veterinary Parasitology (WAAVP) can celebrate its 50th anniversary. At this occasion in this article selected historical data are updated, and the achievements and future perspectives of the WAAVP are discussed. Although the WAAVP is a small association with only a few hundred members, it has been able to develop remarkable activities. Between 1963 and 2011 the WAAVP has organized 23 international scientific congresses, and the 24th conference will take place in Perth, Western Australia, in 2013. These conferences have achieved a high degree of international recognition as indicated by relatively large numbers of participants (up to ~800). Furthermore, the WAAVP has promoted veterinary parasitology in various ways, such as publishing international guidelines (efficacy evaluation of antiparasitic drugs, parasitological methods, standardized nomenclature of animal parasitic diseases "SNOAPAD"), stimulating international discussions on teaching and continued education ("colleges of veterinary parasitology") and by supporting the high quality journal "Veterinary Parasitology" which is the official organ of the WAAVP. In retrospect, the development of the WAAVP can be classified as very successful. New challenges associated with global changes (growth of the world population, urbanization, climate change, new developments in animal and plant production, etc.) will require new efforts in research in various fields, including veterinary parasitology. Future activities of WAAVP may include inter alia: (a) support of international parasitological networks; (b) stimulation of coordinated research aimed at the solution of defined problems; (c) increasing the exposure of WAAVP to parasitology from hitherto neglected regions of the world; (d) strengthening of official links to international organizations (FAO, WHO, etc.); (e) continuation of guideline preparation; and (d) preparation and international distribution of high

    Objective To estimate the proportion of independent small animal veterinary medical practices in Massachusetts that use electronic veterinary medical records (EVMRs), determine the purposes for which EVMRs are used, and identify perceived barriers to their use. Design Survey. Sample 100 veterinarians. Procedures 213 of 517 independent small animal veterinary practices operating in Massachusetts were randomly chosen for study recruitment. One veterinarian at each practice was invited by telephone to answer a hardcopy survey regarding practice demographics, medical records type (electronic, paper, or both), purposes of EVMR use, and perceived barriers to adoption. Surveys were mailed to the first 100 veterinarians who agreed to participate. Practices were categorized by record type and size (large [≥ 5 veterinarians], medium [3 to 4 veterinarians], or small [1 to 2 veterinarians]). Results 84 surveys were returned; overall response was 84 of 213 (39.4%). The EVMRs were used alone or together with paper records in 66 of 82 (80.5%) practices. Large and medium-sized practices were significantly more likely to use EVMRs combined with paper records than were small practices. The EVMRs were most commonly used for ensuring billing, automating reminders, providing cost estimates, scheduling, recording medical and surgical information, and tracking patient health. Least common uses were identifying emerging infectious diseases, research, and insurance. Eleven veterinarians in paper record–only practices indicated reluctance to change, anticipated technological problems, time constraints, and cost were barriers to EVMR use. Conclusions and Clinical Relevance Results indicated EVMRs were underutilized as a tool for tracking and improving population health and identifying emerging infectious diseases. Efforts to facilitate adoption of EVMRs for these purposes should be strengthened by the veterinary medical, human health, and public health professions. PMID:25029312

  7. Connecting knowledge resources to the veterinary electronic health record: opportunities for learning at point of care.

    2011-01-01

    Electronic health records (EHRs) provide clinical learning opportunities through quick and contextual linkage of patient signalment, symptom, and diagnosis data with knowledge resources covering tests, drugs, conditions, procedures, and client instructions. This paper introduces the EHR standards for linkage and the partners-practitioners, content publishers, and software developers-necessary to leverage this possibility in veterinary medicine. The efforts of the American Animal Hospital Association (AAHA) Electronic Health Records Task Force to partner with veterinary practice management systems to improve the use of controlled vocabulary is a first step in the development of standards for sharing knowledge at the point of care. The Veterinary Medical Libraries Section (VMLS) of the Medical Library Association's Task Force on Connecting the Veterinary Health Record to Information Resources compiled a list of resources of potential use at point of care. Resource details were drawn from product Web sites and organized by a metric used to evaluate medical point-of-care resources. Additional information was gathered from questions sent by e-mail and follow-up interviews with two practitioners, a hospital network, two software developers, and three publishers. Veterinarians with electronic records use a variety of information resources that are not linked to their software. Systems lack the infrastructure to use the Infobutton standard that has been gaining popularity in human EHRs. While some veterinary knowledge resources are digital, publisher sites and responses do not indicate a Web-based linkage of veterinary resources with EHRs. In order to facilitate lifelong learning and evidence-based practice, veterinarians and educators of future practitioners must demonstrate to veterinary practice software developers and publishers a clinically-based need to connect knowledge resources to veterinary EHRs.

    To enhance the early detection of emerging infectious diseases and bioterrorism events using companion animal-based surveillance. Washington, DC, small animal veterinary facilities (n=17) were surveyed to determine interest in conducting infectious disease surveillance. Using these results, an electronic-based online reporting system was developed and launched in August 2015 to monitor rates of canine influenza, canine leptospirosis, antibiotic resistant infections, canine parvovirus, and syndromic disease trends. Nine of the 10 facilities that responded expressed interest conducting surveillance. In September 2015, 17 canine parvovirus cases were reported. In response, a campaign encouraging regular veterinary preventative care was launched and featured on local media platforms. Additionally, during the system's first year of operation it detected 5 canine leptospirosis cases and 2 antibiotic resistant infections. No canine influenza cases were reported and syndromic surveillance compliance varied, peaking during National Special Security Events. Small animal veterinarians and the general public are interested in companion animal disease surveillance. The system described can serve as a model for establishing similar systems to monitor disease trends of public health importance in pet populations and enhance biosurveillance capabilities.

    The field of veterinary radiation therapy (RT) has gained substantial momentum in recent decades with significant advances in conformal treatment planning, image-guided radiation therapy (IGRT), and intensity-modulated (IMRT) techniques. At the root of these advancements lie improvements in tumor imaging, image alignment (registration), target volume delineation, and identification of critical structures. Image registration has been widely used to combine information from multimodality images such as computerized tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET) to improve the accuracy of radiation delivery and reliably identify tumor-bearing areas. Many different techniques have been applied in image registration. This review provides an overview of medical image registration in RT and its applications in veterinary oncology. A summary of the most commonly used approaches in human and veterinary medicine is presented along with their current use in IGRT and adaptive radiation therapy (ART). It is important to realize that registration does not guarantee that target volumes, such as the gross tumor volume (GTV), are correctly identified on the image being registered, as limitations unique to registration algorithms exist. Research involving novel registration frameworks for automatic segmentation of tumor volumes is ongoing and comparative oncology programs offer a unique opportunity to test the efficacy of proposed algorithms. © 2016 American College of Veterinary Radiology.

    Understanding the distribution and determinants of disease in animal populations must be underpinned by knowledge of animal demographics. For companion animals, these data have been difficult to collect because of the distributed nature of the companion animal veterinary industry. Here we describe key demographic features of a large veterinary-visiting pet population in Great Britain as recorded in electronic health records, and explore the association between a range of animal's characteristics and socioeconomic factors. Electronic health records were captured by the Small Animal Veterinary Surveillance Network (SAVSNET), from 143 practices (329 sites) in Great Britain. Mixed logistic regression models were used to assess the association between socioeconomic factors and species and breed ownership, and preventative health care interventions. Dogs made up 64.8% of the veterinary-visiting population, with cats, rabbits and other species making up 30.3, 2.0 and 1.6% respectively. Compared to cats, dogs and rabbits were more likely to be purebred and younger. Neutering was more common in cats (77.0%) compared to dogs (57.1%) and rabbits (45.8%). The insurance and microchipping relative frequency was highest in dogs (27.9 and 53.1%, respectively). Dogs in the veterinary-visiting population belonging to owners living in least-deprived areas of Great Britain were more likely to be purebred, neutered, insured and microchipped. The same association was found for cats in England and for certain parameters in Wales and Scotland. The differences we observed within these populations are likely to impact on the clinical diseases observed within individual veterinary practices that care for them. Based on this descriptive study, there is an indication that the population structures of companion animals co-vary with human and environmental factors such as the predicted socioeconomic level linked to the owner's address. This 'co-demographic' information suggests that further

    1999-05-01

    The recent development of optical phased arrays (OPAs) enables practical, electronically programmable, control of laser beams for laser radar and other advanced optical sensors. OPAs are the direct analog of microwave phased array antennas; they are electronically programmable optical elements that control the phase distribution on an optical aperture in order to control beam direction and shape. Operating principles and construction of OPAs are briefly described and current and potential performance capabilities are summarized. An OPA supports spatial-domain beam control such as agile or continuous scanning patterns, adaptive electronic focus control, and far-field beam shape control, as well as the generation of multiple beams from a single input beam (pattern generation, or fanout). OPAs also support time-domain beam control, including precision time delay or positioning of short pulses, pulse compression and expansion, and the generation of dense pulse bursts from a single pulse. All of these functions are software controllable, which enables mission-flexible and mission-adaptive optical systems, including so-called 'smart' optical systems with autonomous alignment and calibration capabilities. These and other electronically programmable capabilities are discussed. As a concrete example of an advanced sensor enabled by the OPA, the potential for an adaptable-format, high-resolution, multi-beam laser radar with no moving parts is discussed.

    Development of the CTF MEG system has been advanced with the introduction of a computer processing cluster between the data acquisition electronics and the host computer. The advent of fast processors, memory, and network interfaces has made this innovation feasible for large data streams at high sampling rates. We have implemented tasks including anti-alias filter, sample rate decimation, higher gradient balancing, crosstalk correction, and optional filters with a cluster consisting of 4 dual Intel Xeon processors operating on up to 275 channel MEG systems at 12 kHz sample rate. The architecture is expandable with additional processors to implement advanced processing tasks which may include e.g., continuous head localization/motion correction, optional display filters, coherence calculations, or real time synthetic channels (via beamformer). We also describe an electronics configuration upgrade to provide operator console access to the peripheral interface features such as analog signal and trigger I/O. This allows remote location of the acoustically noisy electronics cabinet and fitting of the cabinet with doors for improved EMI shielding. Finally, we present the latest performance results available for the CTF 275 channel MEG system including an unshielded SEF (median nerve electrical stimulation) measurement enhanced by application of an adaptive beamformer technique (SAM) which allows recognition of the nominal 20-ms response in the unaveraged signal.

    Nisenhoff, Martin; Superconducting Electronics

    1989-01-01

    The genesis of the NATO Advanced Study Institute (ASI) upon which this volume is based, occurred during the summer of 1986 when we came to the realization that there had been significant progress during the early 1980's in the field of superconducting electronics and in applications of this technology. Despite this progress, there was a perception among many engineers and scientists that, with the possible exception of a limited number of esoteric fundamental studies and applications (e.g., the Josephson voltage standard or the SQUID magnetometer), there was no significant future for electronic systems incorporating superconducting elements. One of the major reasons for this perception was the aversion to handling liquid helium or including a closed-cycle helium liquefier. In addition, many critics felt that IBM's cancellation of its superconducting computer project in 1983 was "proof" that superconductors could not possibly compete with semiconductors in high-speed signal processing. From our persp...

    Full Text Available Today, several veterinary diseases may be treated with the administration of stem cells. This is possible because these cells present a high therapeutic potential and may be injected as autologous or allogenic, freshly isolated, or previously cultured. The literature supports that the process is safe and brings considerable benefits to animal health. Knowledge about how adult stem cells modulate the molecular signals to activate cell homing has also been increasingly determined, evidencing the mechanisms which enable cells to repair and regenerate injured tissues. Preclinical studies were designed for many animal models and they have contributed to the translation to the human clinic. This review shows the most commonly used stem cell types, with emphasis on mesenchymal stem cells and their mechanistic potential to repair, as well as the experimental protocols, studied diseases, and species with the highest amount of studies and applications. The relationship between stem cell protocols utilized on clinics, molecular mechanisms, and the physiological responses may offer subsidies to new studies and therefore improve the therapeutic outcome for both humans and animals.

    2014-01-01

    Veterinary technology has generally established itself well in companion-animal and mixed-animal veterinary medical practice, but the career's growth trajectory is uncertain. Michigan State University (MSU) convened a national conference, "Creating the Future of Veterinary Technology-A National Dialogue," in November 2011 to explore ways to elevate the veterinary technician/technologist's role in the veterinary medical profession and to identify new directions in which the career could expand. Veterinary technicians/technologists might advance their place in private practice by not only improving their clinical skills, but by also focusing on areas such as practice management, leadership training, business training, conflict resolution, information technology, and marketing/communications. Some new employment settings for veterinary technicians/technologists include more participation within laboratory animal medicine and research, the rural farm industry, regulatory medicine, and shelter medicine. Achieving these ends would call for new training options beyond the current 2-year and 4-year degree programs. Participants suggested specialty training programs, hybrid programs of various types, online programs, veterinary technician residency programs of 12-18 months, and more integration of veterinary technician/technology students and veterinary medicine students at colleges of veterinary medicine.

    During the last decade we have been witness to several exciting achievements in electron crystallography. This includes structural and charge density studies on organic molecules complicated inorganic and metallic materials in the amorphous, nano-, meso- and quasi-crystalline state and also development of new software, tailor-made for the special needs of electron crystallography. Moreover, these developments have been accompanied by a now available new generation of computer controlled electron microscopes equipped with high-coherent field-emission sources, cryo-specimen holders, ultra-fast CCD cameras, imaging plates, energy filters and even correctors for electron optical distortions. Thus, a fast and semi-automatic data acquisition from small sample areas, similar to what we today know from imaging plates diffraction systems in X-ray crystallography, can be envisioned for the very near future. This progress clearly shows that the contribution of electron crystallography is quite unique, as it enables to r...

    2012-11-01

    In order to improve the hospital information system of the Chilean University Hospital, the Veterinary Medicine School of Universidad de Chile made a research cooperation with Università San Raffaele Roma to develop and test a new release of the O3-Vet software application. O3-Vet was selected by the Chilean University mainly for two reasons: (1) it uses human medicine standardized technologies such as "Health Level 7" (HL7) and "Integrating the Healthcare Enterprise" (IHE), which allow a good level of data sharing and hospital management; (2) it is open source, which means it can be adapted to specific hospital needs. In the new release, a subset of diagnostic terms was added from the "Systematized Nomenclature of Medicine Clinical Terms" (SNOMED CT), selected by the "American Animal Hospital Association" (AAHA) to standardize the filing of clinical data and its retrieval. Results from a limited survey of veterinarians of the University (n=9) show that the new release improved the management of the Chilean University Hospital and the ability to retrieve useful clinical data.

    2016-01-01

    Full Text Available Stretchable electronics, which offers the performance of conventional wafer-based devices and mechanical properties of a rubber band, enables many novel applications that are not possible through conventional electronics due to its brittle nature. One effective strategy to realize stretchable electronics is to design the inorganic semiconductor material in a stretchable format on a compliant elastomeric substrate. Engineering thermal management is essential for the development of stretchable electronics to avoid adverse thermal effects on its performance as well as in applications involving human body and biological tissues where even 1–2 °C temperature increase is not allowed. This article reviews the recent advances in thermal management of stretchable inorganic electronics with focuses on the thermal models and their comparisons to experiments and finite element simulations.

    While primary health care electronic medical record (EMR) adoption has increased in Canada, the use of advanced EMR features is limited. Realizing the potential benefits of primary health care EMR use is dependent not only on EMR acquisition, but also on its comprehensive use and integration into practice; yet, little is known about the advanced use of EMRs in primary health care. To explore the views of advanced primary health care EMR users practising in a team-based environment. A descriptive qualitative approach was used to explore the views of primary health care practitioners who were identified as advanced EMR users. Twelve individual semi-structured interviews were held with primary health care practitioners in Southwestern Ontario, Canada. Field notes were created after each interview. Interviews were audio recorded and transcribed verbatim. Researchers independently coded the transcripts and then met to discuss the results of the coding. We used a thematic approach to data analysis. Three themes emerged from the data analysis: advanced EMR users as individuals with signature characteristics, advanced EMR users as visionaries and advanced EMR users as agents of change. In any one participant, these elements could overlap, illuminating the important interplay between these themes. Taken together, these themes defined advanced use among this group of primary health care practitioners. To realize the potential benefits of EMR use in improved patient care and outcomes, we need to understand how to support EMR use. This study provides a necessary building block in furthering this understanding.

    Full Text Available Periodontal disease is among the most prevalent canine dis-eases affecting over 75% of dogs. Strengthening of the human-animal bond and the increasing education of the aver-age pet owner, have fostered a heightened awareness of periodontal care in dogs and cats. Industry support has further assisted the small animal veterinarian in providing quality dental treatments and prevention. As recently as the 1990’s, veterinary curriculums contained little or no dental training. That trend is changing as nearly every one of the 28 US Colleges of Veterinary Medicine offers some level of small animal dentistry during the four-year curriculum. Primary areas of focus are on client education, the treatment of periodontal disease, dental prophylaxis, dental radiology, endodontics, exodontics and pain control. Students receive instruction in dental anatomy during their di-dactic curriculum and later experience clinical cases. Graduate DVMs can attend a variety of continuing education courses and even choose to specialize in veterinary dentistry in both small animals and horses. Through the efforts of organizations such as the American Veterinary Dental So-ciety, The American Veterinary Dental College and The Academy of Veterinary Dentistry, many veterinarians have been able to advance their skills in dentistry and improve animal welfare. Increasing ex-pectations of the pet-owning public coupled with the recent advancements of training opportunities available for vete-rinary students, graduate DVMs and certified veterinary technicians make veterinary dentistry an emerging practice-builder among the most successful small animal hospitals.

    1992-01-01

    An advanced electronic system for future EVA missions (including zero gravity, the lunar surface, and the surface of Mars) is under research and development within the Advanced Life Support Division at NASA Ames Research Center. As a first step in the development, an optimum system architecture has been derived from an analysis of the projected requirements for these missions. The open, modular architecture centers around a distributed multiprocessing concept where the major subsystems independently process their own I/O functions and communicate over a common bus. Supervision and coordination of the subsystems is handled by an embedded real-time operating system kernel employing multitasking software techniques. A discussion of how the architecture most efficiently meets the electronic system functional requirements, maximizes flexibility for future development and mission applications, and enhances the reliability and serviceability of the system in these remote, hostile environments is included.

  8. A preface on advances in diagnostics for infectious and parasitic diseases: detecting parasites of medical and veterinary importance.

    Science.gov (United States)

    Stothard, J Russell; Adams, Emily

    2014-12-01

    There are many reasons why detection of parasites of medical and veterinary importance is vital and where novel diagnostic and surveillance tools are required. From a medical perspective alone, these originate from a desire for better clinical management and rational use of medications. Diagnosis can be at the individual-level, at close to patient settings in testing a clinical suspicion or at the community-level, perhaps in front of a computer screen, in classification of endemic areas and devising appropriate control interventions. Thus diagnostics for parasitic diseases has a broad remit as parasites are not only tied with their definitive hosts but also in some cases with their vectors/intermediate hosts. Application of current diagnostic tools and decision algorithms in sustaining control programmes, or in elimination settings, can be problematic and even ill-fitting. For example in resource-limited settings, are current diagnostic tools sufficiently robust for operational use at scale or are they confounded by on-the-ground realities; are the diagnostic algorithms underlying public health interventions always understood and well-received within communities which are targeted for control? Within this Special Issue (SI) covering a variety of diseases and diagnostic settings some answers are forthcoming. An important theme, however, throughout the SI is to acknowledge that cross-talk and continuous feedback between development and application of diagnostic tests is crucial if they are to be used effectively and appropriately.

    Oppermann, M.; Zerna, T.

    2017-02-01

    Advanced electronics packaging is a challenge for non-destructive Testing (NDT). More, smaller and mostly hidden interconnects dominate modern electronics components and systems. To solve the demands of customers to get products with a high functionality by low volume, weight and price (e.g. mobile phones, personal medical monitoring systems) often the designers use System-in-Package solutions (SiP). The non-destructive testing of such devices is a big challenge. So our paper will impart fundamentals and applications for non-destructive evaluation of inner structures of electronics packaging for quality assurance and reliability investigations with a focus on X-ray methods, especially on high resolution X-ray computed tomography (CT).

    Recent technical advancements in radiation therapy have allowed for improved targeting of tumours and sparing nearby normal tissues, while simultaneously decreasing the risk for medical errors by incorporating additional safety checks into electronic medical record keeping systems. The benefits of these new technologies, however, depends on their proper integration and use in the oncology clinic. Despite the advancement of technology for treatment delivery and medical record keeping, misadministration errors have a significant impact on patient care in veterinary oncology. The first part of this manuscript describes a medical incident that occurred at an academic veterinary referral hospital, in a dog receiving a combination of stereotactic radiation therapy and full-course intensity-modulated, image-guided radiation therapy. The second part of the report is a literature review, which explores misadministration errors and novel challenges which arise with the implementation of advancing technologies in veterinary radiation oncology. © 2015 John Wiley & Sons Ltd.

    Whitaker, Sterling

    2015-01-01

    Novel approach enables high-speed special-purpose processors Advanced reconfigurable and reprogrammable communication systems will require sub-130-nanometer electronics. Legacy single event upset (SEU) radiation-tolerant circuits are ineffective at speeds greater than 125 megahertz. In Phase I of this project, ICs, LLC, demonstrated new base-level logic circuits that provide SEU immunity for sub-130-nanometer high-speed circuits. In Phase II, the company developed an innovative self-restoring logic (SRL) circuit and a system approach that provides high-speed, SEU-tolerant solutions that are effective for sub-130-nanometer electronics scalable to at least 22-nanometer processes. The SRL system can be used in the design of NASA's next-generation special-purpose processors, especially reconfigurable communication processors.

Since its inception, many changes have occurred in veterinary medicine such as views on education and didactic learning, demographics of our profession, and standards of practice in animal husbandry, medicine, surgery, anesthesia, and vaccinology. In fact, the concept of infectious diseases has changed - remember the germ theory was proposed a mere 140 years ago. However, one constant tenet in our profession has been the need to disseminate progresses, innovations, advances, and developments in veterinary sciences. Published reports are the foundation for the growth of medicine and science. What would the state of medicine be if Pasteur, Koch, Bourgelat, or Theobald Smith had not published their works?

  3. The future of veterinary parasitology.

    Science.gov (United States)

    Coles, G C

    2001-07-12

    Current evidence suggests research in veterinary parasitology is in decline despite its importance. This is particularly true in the UK where research funds have been diverted into BSE. Decline in interest in veterinary parasitology is at least in part due to the success of major pharmaceutical companies in producing a range of effective and safe anti-parasitic drugs. Research is needed because of the effects of parasites on animal welfare and the economic costs of parasites. However, there is little information on the actual costs of animal parasites. Another major reason for research is the development of drug resistance in protozoa, helminths and arthropods of veterinary importance. This is a serious problem particularly for sheep and goats in the southern hemisphere. A prioritised list of research requirements is suggested: (i) new drugs; (ii) resistance management; (iii) vaccines; (iv) breeding for resistance; (v) improved diagnostics; (vi) zoonoses; (vii) global warming and parasites. There is a major political challenge to raise the profile of veterinary parasitology and thus the funding essential for its advancement and the continued welfare and productivity of animals.

    1997-11-01

    This final report chronicles a three-year, Laboratory Directed Research and Development (LDRD) project at Los Alamos National Laboratory (LANL). The High-Resolution Electron Microscopy Facility has doubled in size and tripled in quality since the beginning of the three-year period. The facility now includes a field-emission scanning electron microscope, a 100 kV field-emission scanning transmission electron microscope (FE-STEM), a 300 kV field-emission high-resolution transmission electron microscope (FE-HRTEM), and a 300 kV analytical transmission electron microscope. A new orientation imaging microscope is being installed. X-ray energy dispersive spectrometers for chemical analysis are available on all four microscopes; parallel electron energy loss spectrometers are operational on the FE-STEM and FE-HRTEM. These systems enable evaluation of local atomic bonding, as well as chemical composition in nanometer-scale regions. The FE-HRTEM has a point-to-point resolution of 1.6 {angstrom}, but the resolution can be pushed to its information limit of 1 {angstrom} by computer reconstruction of a focal series of images. HRTEM has been used to image the atomic structure of defects such as dislocations, grain boundaries, and interfaces in a variety of materials from superconductors and ferroelectrics to structural ceramics and intermetallics.

    The development of a transmission electron microscope equipped with a field emission gun paved the way for electron holography to be put to practical use in various fields. In this paper, we review three advanced electron holography techniques: on-line real-time electron holography, three-dimensional (3D) tomographic holography and phase-shifting electron holography, which are becoming important techniques for materials science and device engineering. We also describe some applications of electron holography to the analysis of industrial materials and devices: GaAs compound semiconductors, solid oxide fuel cells and all-solid-state lithium ion batteries.

  12. Electron beam melting of advanced materials and structures

    Science.gov (United States)

    Mahale, Tushar Ramkrishna

    Layered manufacturing has for long been used for the fabrication of non-functional parts using polymer-based processes. Developments in laser beam and electron beam welding technologies and their adoption to layered manufacturing has made it possible to fabricate high-density functional parts in metal irrespective of the level of complexity. The Electron Beam Melting (EBM) process by Arcam AB is one such layered manufacturing process that utilizes a focused electron beam to process metal powder, layer by layer, in a vacuum environment. Research conducted as part of this body of work looks into the development of both bulk materials in the form of metal alloys and ceramic metal-matrix composites as well as the development of tunable mechanical & thermal metamaterials. Simulation models to approximate electron beam melting were suggested using commercial finite element analysis packages. A framework was developed based on the finite difference method to simulate layered manufacturing using Arcam AB's electron beam melting process. The outputs from the simulation data could be used to better understand the local melting, grain evolution, composition and internal stresses within freeform-fabricated metal parts.

  13. Advanced ponderomotive description of electron acceleration in ICRF discharge initiation

    Science.gov (United States)

    Wauters, Tom; Tripský, Matej; Lyssoivan, Anatoli; Louche, Fabrice; Möller, Sören; Ragona, Riccardo; Van Eester, Dirk

    2017-10-01

    This contribution proposes a new approach for the ponderomotive description of electron acceleration in ICRF discharge initiation. The motion of electrons in the parallel electric field Ez is separated into a fast oscillation and a slower drift around the oscillation centre. Three terms are maintained in the Taylor expansion of the electric field (0th , 1st and 2nd order). The efficiency for electron acceleration by Ez (z, t) is then assessed by comparing the values of these terms at the slow varying coordinate z0 . When (i) the 0th order term is not significantly larger than 1st order term at the reflection point, or when (ii) the 2nd order term is negative and not sufficiently small compared to the 1st order term at the reflection point, then the electron will gain energy in the reflection. An example for plasma production by the TOMAS ICRF system is given. Following the described conditions it can be derived that plasma production is (i) most efficient close to the antenna straps (few cm's) where the field gradient and amplitude are large, and (ii) that the lower frequency field accelerates electrons more easily for a given antenna voltage.

    White, Bruce; Mazmanian, Edward; Tapio, Eric

    2016-01-01

    DLR's Eu:CROPIS (Euglena and Combined Regenerative Organic-Food Production in Space) mission, launching in 2017, will carry multiple biological payloads into a sun-synchronous orbit, including NASA Ames' PowerCell experiment. PowerCell will attempt to characterize the viability of synthetic biology at micro-g, Lunar, and Martian gravity levels. PowerCell experiment requirements demand an electronic system similar to previous microfluidic biology payloads, but with an expanded feature set. As such, the system was based on PharmaSat (Diaz-Aguado et al. 2009), a previous successful biology payload from NASA Ames, and improved upon. Newer, more miniaturized electronics allow for greater capability with a lower part count and smaller size. Two identical PowerCell enclosures will fly. Each enclosure contains two separate and identical experiments with a 48-segment optical density measurement system, grow light system, microfluidic system for nutrient delivery and waste flushing, plus thermal control and environmental sensing/housekeeping including temperature, pressure, humidity, and acceleration. Electronics consist of a single Master PCB that interfaces to the spacecraft bus and regulates power and communication, plus LED, Detector, and Valve Manifold PCBs for each experiment. To facilitate ease of reuse on future missions, experiment electronics were designed to be compatible with a standard 3U small sat form factor and power bus, or to interface with a Master power/comm PCB for use in a larger satellite as in the case of PowerCell's flight on Eu:CROPIS.

    2017-08-01

    Conductive nanocomposites have emerged as significant smart engineered materials for realizing flexible electronics on diverse substrates in recent years. Conductive nanocomposites are comprised of conductive fillers mixed with polymeric elastomer (e.g. polydimethylsiloxane). The possibility to tune electrical as well as mechanical properties of nanocomposites makes them suitable for a wide spectrum of applications including sensors and electronics on non-planar and stretchable surfaces. A number of conductive nanofillers and manufacturing technologies have been developed to meet the diverse requirements of various applications. Considering the substantial contribution of conductive nanocomposites, it is opportune time to review the potentials of various nanofillers, their synthesis, processing methodologies and challenges associated to them. This paper reviews conductive nanocomposites, especially in context with their use in the development of electronic components and the sensors exploiting the piezoresistive behavior. The paper is structured around the nanocomposites related studies aiming to develop various building blocks of flexible electronic skin systems such as pressure, touch, strain and temperature sensors as well as stretchable interconnects. Besides this, the use of nanocomposites in other stimulating industrial and biomedical applications has also been explored briefly.

    2017-06-01

    Molecular electronics stands for the ultimate size of functional elements, keeping up with an unstoppable trend over the past few decades. As a vital component of molecular electronics, single molecular junctions have attracted significant attention from research groups all over the world. Due to its pronounced superiority, the mechanically controllable break junctions (MCBJ) technique has been widely applied to characterize the dynamic performance of single molecular junctions. This review presents a system analysis for single-molecule junctions and offers an overview of four test-beds for single-molecule junctions, thus offering more insight into the mechanisms of electron transport. We mainly focus on the development of state-of-the-art mechanically controlled break junctions. The three-terminal gated MCBJ approaches are introduced to manipulate the electron transport of molecules, and MCBJs are combined with characterization techniques. Additionally, applications of MCBJs and remarkable properties of single molecules are addressed. Finally, the challenges and perspective for the mechanically controllable break junctions technique are provided.

    2005-01-01

    Our overall intent in this aspect of the project were to establish a collaborative effort between several departments at Montana State University for developing advanced optoelectronic technology for advancing the state-of-the-art in optical remote sensing of the environment. Our particular focus was on development of small systems that can eventually be used in a wide variety of applications that might include ground-, air-, and space deployments, possibly in sensor networks. Specific objectives were to: 1) Build a field-deployable direct-detection lidar system for use in measurements of clouds, aerosols, fish, and vegetation; 2) Develop a breadboard prototype water vapor differential absorption lidar (DIAL) system based on highly stable, tunable diode laser technology developed previously at MSU. We accomplished both primary objectives of this project, in developing a field-deployable direct-detection lidar and a breadboard prototype of a water vapor DIAL system. Paper summarizes each of these accomplishments.

    Harrysson, Ola L. A.; Marcellin-Little, Denis J.; Horn, Timothy J.

    2015-03-01

    Veterinary medicine has undergone a rapid increase in specialization over the last three decades. Veterinarians now routinely perform joint replacement, neurosurgery, limb-sparing surgery, interventional radiology, radiation therapy, and other complex medical procedures. Many procedures involve advanced imaging and surgical planning. Evidence-based medicine has also become part of the modus operandi of veterinary clinicians. Modeling and additive manufacturing can provide individualized or customized therapeutic solutions to support the management of companion animals with complex medical problems. The use of metal additive manufacturing is increasing in veterinary orthopedic surgery. This review describes and discusses current and potential applications of metal additive manufacturing in veterinary orthopedic surgery.

  4. Electronic Nose Odor Classification with Advanced Decision Tree Structures

    Directory of Open Access Journals (Sweden)

    S. Guney

    2013-09-01

    Full Text Available Electronic nose (e-nose is an electronic device which can measure chemical compounds in air and consequently classify different odors. In this paper, an e-nose device consisting of 8 different gas sensors was designed and constructed. Using this device, 104 different experiments involving 11 different odor classes (moth, angelica root, rose, mint, polis, lemon, rotten egg, egg, garlic, grass, and acetone were performed. The main contribution of this paper is the finding that using the chemical domain knowledge it is possible to train an accurate odor classification system. The domain knowledge about chemical compounds is represented by a decision tree whose nodes are composed of classifiers such as Support Vector Machines and k-Nearest Neighbor. The overall accuracy achieved with the proposed algorithm and the constructed e-nose device was 97.18 %. Training and testing data sets used in this paper are published online.

  5. Research data services in veterinary medicine libraries.

    Science.gov (United States)

    Kerby, Erin E

    2016-10-01

    The study investigated veterinary medicine librarians' experience with and perceptions of research data services. Many academic libraries have begun to offer research data services in response to researchers' increased need for data management support. To date, such services have typically been generic, rather than discipline-specific, to appeal to a wide variety of researchers. An online survey was deployed to identify trends regarding research data services in veterinary medicine libraries. Participants were identified from a list of contacts from the MLA Veterinary Medical Libraries Section. Although many respondents indicated that they have a professional interest in research data services, the majority of veterinary medicine librarians only rarely or occasionally provide data management support as part of their regular job responsibilities. There was little consensus as to whether research data services should be core to a library's mission despite their perceived importance to the advancement of veterinary research. Furthermore, most respondents stated that research data services are just as or somewhat less important than the other services that they provide and feel only slightly or somewhat prepared to offer such services. Lacking a standard definition of "research data" and a common understanding of precisely what research data services encompass, it is difficult for veterinary medicine librarians and libraries to define and understand their roles in research data services. Nonetheless, they appear to have an interest in learning more about and providing research data services.

    2008-12-01

    The rapid development in the fields of electroscience, computer science, and biomedical engineering are propelling the electrophysiologyical techniques. Recent technological advances have made it possible to simultaneously record the activity of large numbers of neurons in awake and behaving animals using implanted extracellular electrodes. Several laboratories use chronically implanted electrode arrays in freely moving animals because they allow stable recordings of discriminated single neurons and/or field potentials from up to hundreds of electrodes over long time periods. In this review, we focus on the new technologies for neuroelectrophysiology.

    2017-06-28

    Faculty attrition and recruitment for veterinary clinical faculty positions have been reported as significant problems in veterinary medical education. To investigate the factors that may be important in veterinary clinical faculty retention, the perceptions and views of veterinary clinical academic faculty were determined using a web-distributed electronic survey. Responses were dichotomized by whether the respondent had or had not left an academic position and were analyzed for their association with faculty attrition. A total of 1,226 responses were recorded and results demonstrated that factors other than compensation were associated with veterinary clinical faculty attrition, including departmental culture, work-life balance, and recognition and support of clinical medicine by the administration. Forty-four percent of respondents who had held a faculty appointment reported leaving academia either voluntarily or for non-voluntary reasons such as failure to achieve tenure, retirement, or having their position closed. Attention to correcting deficiencies in workplace culture and professional rewards could be a beneficial means by which to decrease the faculty attrition rates currently observed in clinical academic veterinary medicine.

  10. Thin dielectric film thickness determination by advanced transmission electron microscopy

    2003-09-01

    High Resolution Transmission Electron Microscopy (HR-TEM) has been used as the ultimate method of thickness measurement for thin films. The appearance of phase contrast interference patterns in HR-TEM images has long been confused as the appearance of a crystal lattice by non-specialists. Relatively easy to interpret crystal lattice images are now directly observed with the introduction of annular dark field detectors for scanning TEM (STEM). With the recent development of reliable lattice image processing software that creates crystal structure images from phase contrast data, HR-TEM can also provide crystal lattice images. The resolution of both methods was steadily improved reaching now into the sub Angstrom region. Improvements in electron lens and image analysis software are increasing the spatial resolution of both methods. Optimum resolution for STEM requires that the probe beam be highly localized. In STEM, beam localization is enhanced by selection of the correct aperture. When STEM measurement is done using a highly localized probe beam, HR-TEM and STEM measurement of the thickness of silicon oxynitride films agree within experimental error. In this paper, the optimum conditions for HR-TEM and STEM measurement are discussed along with a method for repeatable film thickness determination. The impact of sample thickness is also discussed. The key result in this paper is the proposal of a reproducible method for film thickness determination.

    Electron tomography in materials science has flourished with the demand to characterize nanoscale materials in three dimensions (3D). Access to experimental data is vital for developing and validating reconstruction methods that improve resolution and reduce radiation dose requirements. This work presents five high-quality scanning transmission electron microscope (STEM) tomography datasets in order to address the critical need for open access data in this field. The datasets represent the current limits of experimental technique, are of high quality, and contain materials with structural complexity. Included are tomographic series of a hyperbranched Co2P nanocrystal, platinum nanoparticles on a carbon nanofibre imaged over the complete 180° tilt range, a platinum nanoparticle and a tungsten needle both imaged at atomic resolution by equal slope tomography, and a through-focal tilt series of PtCu nanoparticles. A volumetric reconstruction from every dataset is provided for comparison and development of post-processing and visualization techniques. Researchers interested in creating novel data processing and reconstruction algorithms will now have access to state of the art experimental test data.

  12. Advanced Electron Beam Diagnostics for the FERMI FEL

    CERN Document Server

    Ferianis, M; D'Auria, G; Di Mitri, S

    2005-01-01

    Fermi is the fourth generation light source currently under design at ELETTRA: based on the Harmonic Generation (HG) scheme it will generate FEL radiation in the 100-10nm range. The successful implementation of the HG scheme calls also for precise knowledge of electron beam emittances and energy spread as well as for very accurate control on the photon to electron interaction, in the Undulator sections. In this paper we present our design for two fundamental Diagnostics foreseen for the new FERMI LINAC: the Beam Position Monitors (BPM) and the Transverse Deflecting cavity set-up. Sensitivity studies on transverse beam displacement effects on global stability of FEL output radiation dictate the ultimate performance to be provided by the BPM system. Due to non negligible longitudinal occupancy of a cavity type BPM, some efforts have been put to study compact cavity BPM configuration. A proper set-up of RF deflecting cavity combined with the vertical ramp foreseen at the end of the LINAC provide a powerful tool ...

    2007-01-01

    It has been shown in this work that the Fourier space approach can be fruitfully applied to the calculation of the fields and the associated electron optical phase shift of several magnetic and electrostatic structures, like superconducting vortices in conventional and high-T{sub c} superconductors, reverse biased p-n junctions, magnetic domains and nanoparticles. In all these cases, this novel approach has led to unexpected but extremely interesting results, very often expressed in analytical form, which allow the quantitative and reliable interpretation of the experimental data collected by means of electron holography or of more conventional Lorentz microscopy techniques. Moreover, it is worth recalling that whenever long-range electromagnetic fields are involved, a physical model of the object under investigation is necessary in order to take into account correctly the perturbation of the reference wave induced by the tail of the field protruding into the vacuum. For these reasons, we believe that the Fourier space approach for phase computations we have introduced and discussed in this chapter will represent an invaluable tool for the investigation of electromagnetic fields at the meso- and nano-scale.

    1980-01-01

    The desirability of seven advanced technologies as applied to three commercial aircraft of 1985 to 1995 was investigated. Digital fly by wire, multiplexing, ring laser gyro, integrated avionics, all electric airplane, electric load management, and fiber optics were considered for 500 passenger, 50 passenger, and 30 passenger aircraft. The major figure of merit used was Net Value of Technology based on procurement and operating cost over the life of the aircraft. An existing computer program, ASSET, was used to resize the aircraft and evalute fuel usage and maintenance costs for each candidate configuration. Conclusions were that, for the 500 passenger aircraft, all candidates had a worthwhile payoff with the all electric airplane having a large payoff.

    In this work, the simultaneous iterative reconstruction technique (SIRT), the total variation minimization (TVM) reconstruction technique and the discrete algebraic reconstruction technique (DART) for electron tomography are compared and the advantages and disadvantages are discussed. Furthermore, we describe how the result of a three dimensional (3D) reconstruction based on TVM can provide objective information that is needed as the input for a DART reconstruction. This approach results in a tomographic reconstruction of which the segmentation is carried out in an objective manner. - Highlights: ► A comparative study between different reconstruction algorithms for tomography is performed. ► Reconstruction algorithms that uses prior knowledge about the specimen have a superior result. ► One reconstruction algorithm can provide the prior knowledge for a second algorithm.

  16. Status and Perspectives of Ion Track Electronics for Advanced Biosensing

    Fink, D.; Muñoz, H. Gerardo; Alfonta, L.; Mandabi, Y.; Dias, J. F.; de Souza, C. T.; Bacakova, L. E.; Vacík, J.; Hnatowicz, V.; Kiv, A. E.; Fuks, D.; Papaleo, R. M.

    New multifunctional ion irradiation-based three-dimensional electronic structures are developed for biotechnological applications, specifically for sensing of biomaterials, bacteria and mammalian cells. This is accomplished by combined micrometric surface and nanometric bulk microstructuring of insulators (specifically of polymer foils and SiO2/Si hybride structures) by adequate ion beams. Our main goal is the production of a cheap small universal generic working platform with multifunctional properties for biomedical analysis. Surface engineering of this platform enables cell bonding and its bulk engineering enables the extraction of cell secrets, for the sake of intercepting and analyzing the biomolecules used in cell communication. The exact knowledge of the spectrum of these cell-secreted signalling molecules should enable one to identify unambiguously the cell type. This knowledge will help developing strategies for preventive quorum sensing of bacteria, with the aim of fighting bacterial infections in an ecologically secure way.

  17. Topology Zero: Advancing Theory and Experimentation for Power Electronics Education

    Science.gov (United States)

    Luchino, Federico

    For decades, power electronics education has been based on the fundamentals of three basic topologies: buck, boost, and buck-boost. This thesis presents the analytical framework for the Topology Zero, a general circuit topology that integrates the basic topologies and provides significant insight into the behaviour of converters. As demonstrated, many topologies are just particular cases of the Topology Zero, an important contribution towards the understanding, integration, and conceptualization of topologies. The investigation includes steady-state, small-signal, and frequency response analysis. The Topology Zero is physically implemented as an educational system. Experimental results are presented to show control applications and power losses analysis using the educational system. The steady-state and dynamic analyses of the Topology Zero provide profuse proof of its suitability as an integrative topology, and of its ability to be indirectly controlled. As well, the implementation of the Topology Zero within an experimentation system is explained and application examples are provided.

  18. Advanced cluster methods for correlated-electron systems

    Energy Technology Data Exchange (ETDEWEB)

    Fischer, Andre

    2015-04-27

    In this thesis, quantum cluster methods are used to calculate electronic properties of correlated-electron systems. A special focus lies in the determination of the ground state properties of a 3/4 filled triangular lattice within the one-band Hubbard model. At this filling, the electronic density of states exhibits a so-called van Hove singularity and the Fermi surface becomes perfectly nested, causing an instability towards a variety of spin-density-wave (SDW) and superconducting states. While chiral d+id-wave superconductivity has been proposed as the ground state in the weak coupling limit, the situation towards strong interactions is unclear. Additionally, quantum cluster methods are used here to investigate the interplay of Coulomb interactions and symmetry-breaking mechanisms within the nematic phase of iron-pnictide superconductors. The transition from a tetragonal to an orthorhombic phase is accompanied by a significant change in electronic properties, while long-range magnetic order is not established yet. The driving force of this transition may not only be phonons but also magnetic or orbital fluctuations. The signatures of these scenarios are studied with quantum cluster methods to identify the most important effects. Here, cluster perturbation theory (CPT) and its variational extention, the variational cluster approach (VCA) are used to treat the respective systems on a level beyond mean-field theory. Short-range correlations are incorporated numerically exactly by exact diagonalization (ED). In the VCA, long-range interactions are included by variational optimization of a fictitious symmetry-breaking field based on a self-energy functional approach. Due to limitations of ED, cluster sizes are limited to a small number of degrees of freedom. For the 3/4 filled triangular lattice, the VCA is performed for different cluster symmetries. A strong symmetry dependence and finite-size effects make a comparison of the results from different clusters difficult

    2011-03-01

    These guidelines for veterinary medical care and veterinary hospitals are written to conform with the requirements of the Animal Welfare Act, which states that programs of disease prevention and parasite control, euthanasia, and adequate veterinary care shall be established and maintained under the supervision of a veterinarian. Ideally the zoo and aquarium should be providing the best possible veterinary medical care for the animals in their collections. Many of these animals are rare and endangered and the institutions should endeavor both to provide for the long term health and well being of these animals and to advance the field of non-domestic animal medicine. It is hoped that this publication will aid in this process.

  1. The Assurance Challenges of Advanced Packaging Technologies for Electronics

    Science.gov (United States)

    Sampson, Michael J.

    2010-01-01

    Advances in microelectronic parts performance are driving towards finer feature sizes, three-dimensional geometries and ever-increasing number of transistor equivalents that are resulting in increased die sizes and interconnection (I/O) counts. The resultant packaging necessary to provide assemble-ability, environmental protection, testability and interconnection to the circuit board for the active die creates major challenges, particularly for space applications, Traditionally, NASA has used hermetically packaged microcircuits whenever available but the new demands make hermetic packaging less and less practical at the same time as more and more expensive, Some part types of great interest to NASA designers are currently only available in non-hermetic packaging. It is a far more complex quality and reliability assurance challenge to gain confidence in the long-term survivability and effectiveness of nonhermetic packages than for hermetic ones. Although they may provide more rugged environmental protection than the familiar Plastic Encapsulated Microcircuits (PEMs), the non-hermetic Ceramic Column Grid Array (CCGA) packages that are the focus of this presentation present a unique combination of challenges to assessing their suitability for spaceflight use. The presentation will discuss the bases for these challenges, some examples of the techniques proposed to mitigate them and a proposed approach to a US MIL specification Class for non-hermetic microcircuits suitable for space application, Class Y, to be incorporated into M. IL-PRF-38535. It has recently emerged that some major packaging suppliers are offering hermetic area array packages that may offer alternatives to the nonhermetic CCGA styles but have also got their own inspectability and testability issues which will be briefly discussed in the presentation,

    Korian is a private group specializing in medical accommodations for elderly and dependent people. A professional data warehouse (DWH) established in 2010 hosts all of the residents' data. Inside this information system (IS), clinical narratives (CNs) were used only by medical staff as a residents' care linking tool. The objective of this study was to show that, through qualitative and quantitative textual analysis of a relatively small physiotherapy and well-defined CN sample, it was possible to build a physiotherapy corpus and, through this process, generate a new body of knowledge by adding relevant information to describe the residents' care and lives. Meaningful words were extracted through Standard Query Language (SQL) with the LIKE function and wildcards to perform pattern matching, followed by text mining and a word cloud using R® packages. Another step involved principal components and multiple correspondence analyses, plus clustering on the same residents' sample as well as on other health data using a health model measuring the residents' care level needs. By combining these techniques, physiotherapy treatments could be characterized by a list of constructed keywords, and the residents' health characteristics were built. Feeding defects or health outlier groups could be detected, physiotherapy residents' data and their health data were matched, and differences in health situations showed qualitative and quantitative differences in physiotherapy narratives. This textual experiment using a textual process in two stages showed that text mining and data mining techniques provide convenient tools to improve residents' health and quality of care by adding new, simple, useable data to the electronic health record (EHR). When used with a normalized physiotherapy problem list, text mining through information extraction (IE), named entity recognition (NER) and data mining (DM) can provide a real advantage to describe health care, adding new medical material and

  4. Telemedicine in veterinary practice

    Full Text Available Veterinary surgeons have a long tradition of consulting one another about problem cases and many have unwittingly practised telemedicine when discussing cases by telephone or by sending laboratory reports by telefax. Specific veterinary telemedicine applications have been in use since the early 1980s, but little research has been undertaken in this field. The Pubmed and CAB International databases were searched for the following Boolean logic-linked keywords; veterinary AND telemedicine, veterinary AND telecare, animal AND telemedicine, animal AND telecare and veterinary AND e-mail and an additional search was made of the worldwide web, using Google Scholar. This returned 25 papers which were reviewed. Of these only 2 report research. Sixteen papers had no references and 1 author was associated with 13 papers. Several themes emerge in the papers reviewed. These include remarks about the use of telemedicine, the benefits that can and are derived from the use of telemedicine, areas of practice in which telemedicine is being used, ethical and legal issues around the practice of telemedicine, image standards required for telemedicine, the equipment that is required for the practice of telemedicine, advice on ways in which digital images can be obtained and educational aspects of telemedicine. These are discussed. Veterinary practice has lagged behind its human counterpart in producing research on the validity and efficacy of telemedicine. This is an important field which requires further research.

    Antimicrobial resistance has emerged in recent years as a significant public health threat, which requires both an ethical and a scientific approach. In a recent Policy Delphi study, on-farm use of antimicrobials was a key concern identified by veterinary professionals in Ireland. In this case study (the second in a series of three resulting from a research workshop exploring the challenges facing the veterinary profession in Ireland; the other two case studies investigate clinical veterinary services and emergency/casualty slaughter certification) we aim to provide a value-based reflection on the constraints and possible opportunities for responsible use of veterinary antimicrobials in Ireland. Using a qualitative focus group approach, this study gathered evidence from relevant stakeholders, namely veterinarians working in public and private organisations, a representative from the veterinary regulatory body, a dairy farmer and a general medical practitioner. Three overarching constraints to prudent on-farm use of veterinary antimicrobials emerged from the thematic analysis: 'Defective regulations', 'Lack of knowledge and values' regarding farmers and vets and 'Farm-centred concerns', including economic and husbandry concerns. Conversely, three main themes which reflect possible opportunities to the barriers were identified: 'Improved regulations', 'Education' and 'Herd health management'. Five main recommendations arose from this study based on the perspectives of the study participants including: a) the potential for regulatory change to facilitate an increase in the number of yearly visits of veterinarians to farms and to implement electronic prescribing and shorter validity of prescriptions; b) a 'One Health' education plan; c) improved professional guidance on responsible use of veterinary antimicrobials; d) improved on-farm herd health management practices; and e) the promotion of a 'One Farm-One Vet' policy. These findings may assist Veterinary Council of

    Transmission Electron Microscopy evolves rapidly as a primary tool to investigate nano structures on a truly atomic level. Its resolution reaches into the sub Angstrom region by now. Together with a better correction of lens aberrations, sensitivities are drastically enhanced. Utilizing advanced electron microscopes, it is feasible to promote experiments that aim to detect single atoms. This enables local investigations of non-stoichiometry. This paper reviews the current state-of-the-art.

    The public needs no reminder that deadly infectious diseases such as FMD could emerge in any country at any moment, or that national food security could be compromised by Salmonella or Listeria infections. Protections against these risks include the knowledge that appropriate and equivalent veterinary education will enable detection and characterization of emerging disease agents, as well as an appropriate response, wherever they occur. Global veterinary leadership is needed to reduce the global threat of infectious diseases of major food animal and public health importance. We believe that the co-curriculum is an excellent way to prepare and train veterinarians and future leaders who understand and can deal with global issues. The key to the success of the program is the veterinarian's understanding that there is a cultural basis to the practice of veterinary medicine in any country. The result will be a cadre of veterinarians, faculty, and other professionals who are better able (language and culture) to understand the effects of change brought about by free trade and the importance of interdisciplinary and institutional relationships to deal effectively with national and regional issues of food safety and security. New global veterinary leadership programs will build on interests, experience, ideas, and ambitions. A college that wishes to take advantage of this diversity must offer opportunities that interest veterinarians throughout their careers and that preferably connect academic study with intensive experiential training in another country. At its best, the global veterinary leadership program would include a partnership between veterinarians and several international learning centers, a responsiveness to the identified international outreach needs of the profession, and attention to critical thinking and reflection. The global veterinary leadership program we have described is intended to be a set of ideas meant to promote collaboration, coalitions, and

  10. Lessons of history in veterinary medicine.

    Science.gov (United States)

    Smith, Donald F

    2013-01-01

    The future of veterinary medicine is best understood in the context of history. What began as a profession rooted in urban centers in proximity to horses, physicians, and medical schools, was transformed into a land grant-based agricultural profession with the arrival of the internal combustion engine in the early twentieth century. Most of the United States' current veterinary colleges are still located in towns or small cities in the middle section of the country, outside the largest metropolitan areas where most veterinarians practice companion-animal medicine. Throughout veterinarian history, substantial numbers of US students have been educated in foreign colleges and this continues today, creating an even greater geographic imbalance between the veterinary educational process and US population centers and major medical schools. Three themes deserve special attention as we celebrate the profession's 150th anniversary. We must first move beyond the land-grant culture and develop a more geographically balanced approach to establishing new veterinary colleges that are also in closer association with schools of medicine and public health. We must also facilitate more opportunities for women leadership in organized veterinary medicine, in practice ownership, in academia, and in the corporate structures that educate, hire, and interface with veterinarians. Finally, we need to expand our understanding of One Health to include the concept of zooeyia (the role of animals in promoting human health), as well as continue to emphasize veterinarians' special roles in the control and management of zoonotic diseases and in advancing comparative medicine in the age of the genome.

    At Shanghai Jiao Tong University, we have established a research laboratory for advanced acceleration research based on high-power lasers and plasma technologies. In a primary experiment based on the laser wakefield acceleration (LWFA) scheme, multi-hundred MeV electron beams having a reasonable quality are generated using 20-40 TW, 30 femtosecond laser pulses interacting independently with helium, neon, nitrogen and argon gas jet targets. The laser-plasma interaction conditions are optimized for stabilizing the electron beam generation from each type of gas. The electron beam pointing angle stability and divergence angle as well as the energy spectra from each gas jet are measured and compared.

    As the most ambitious concept of isotope separation on line (ISOL) facility, EURISOL aims at producing unprecedented intensities of post-accelerated radioactive isotopes. Charge breeding, which transforms the charge state of radioactive beams from 1+ to an n+ charge state prior to post-acceleration, is a key technology which has to overcome the following challenges: high charge states for high energies, efficiency, rapidity and purity. On the roadmap to EURISOL, a dedicated R&D is being undertaken to push forward the frontiers of the present state-of-the-art techniques which use either electron cyclotron resonance or electron beam ion sources. We describe here the guidelines of this R&D.

    2016-09-01

    An electronic survey was conducted to determine the attitudes of veterinary pathologists toward forensic pathology and the adequacy of their training in the discipline. The survey was sent to 1933 diplomates of the American College of Veterinary Pathologists and 311 completed responses were analyzed. Of respondents, 80% report receiving at least 1 type of medicolegal case, with cases from law enforcement received most frequently. Most (74%) of the respondents indicated that their previous training did not prepare them adequately to handle forensic cases and almost half of the respondents (48%) indicated that they needed more training on serving as an expert witness. Relative risk ratios (RRR) and odds ratios (OR) were generated to determine the strength of a statistically significant association. Responses from a free-text entry question determining additional training needs could be grouped into 3 main categories: (1) veterinary forensic pathology science and procedures, (2) documentation, evidence collection and handling, and (3) knowledge of the medicolegal system. Last, a field for additional comments or suggestions regarding veterinary forensic pathology was completed by 107 respondents and many reinforced the need for training in the categories previously described. The survey highlights that a significant proportion of diplomates of the American College of Veterinary Pathologists are currently engaged in veterinary forensic pathology but feel their training has not adequately prepared them for these cases. Hopefully, the survey results will inform the college and residency training coordinators as they address the training requirements for an important emerging discipline. © The Author(s) 2016.

  16. Veterinary Forensic Toxicology.

    Gwaltney-Brant, S M

    2016-09-01

    Veterinary pathologists working in diagnostic laboratories are sometimes presented with cases involving animal poisonings that become the object of criminal or civil litigation. Forensic veterinary toxicology cases can include cases involving animal cruelty (malicious poisoning), regulatory issues (eg, contamination of the food supply), insurance litigation, or poisoning of wildlife. An understanding of the appropriate approach to these types of cases, including proper sample collection, handling, and transport, is essential so that chain of custody rules are followed and proper samples are obtained for toxicological analysis. Consultation with veterinary toxicologists at the diagnostic laboratory that will be processing the samples before, during, and after the forensic necropsy can help to ensure that the analytical tests performed are appropriate for the circumstances and findings surrounding the individual case. © The Author(s) 2016.

    To review the updates in the American Heart Association (AHA) guidelines for cardiopulmonary resuscitation (CPR) and identify potential applications to veterinary patients. Cardiopulmonary arrest is common in veterinary emergency and critical care, and consensus guidelines are lacking. Human resuscitation guidelines are continually evolving as new clinical and experimental studies support updated recommendations. Synthesis of human, experimental animal model, and veterinary literature support the potential for updates and advancement in veterinary CPR practices. This review serves to highlight updates in the AHA guidelines for CPR and evaluate their application to small animal veterinary patients. Interventions identified will be evaluated for trans-species potential, raise questions regarding best resuscitation recommendations, and offer opportunities for further research to continue to advance veterinary CPR. The prognosis for any patient undergoing cardiopulmonary arrest remains guarded. © Veterinary Emergency and Critical Care Society 2012.

  19. Distance learning in veterinary medicine: enhancing interactivity in continuing education.

    Science.gov (United States)

    Ferguser, D C; Pion, P D

    1996-05-01

    Technological advances have made distance veterinary continuing education a reality. Distance interactive continuing education programs using computer and modern are currently being offered via Veterinary Information Network (VIN) on the America Online (AOL) computer network and the Network of Animal Health (NOAH) on CompuServe. Using over 500 hours of course experience on VIN as an example, this article describes the technology involved in delivering online instruction including electronic mail, asynchronous bulletin board interactions, electronic library files, and realtime interactive discussions. These formats take advantage of the standard features of the network AOL are mixed with links to Worldwide Web sites, print and electronic publications, and even coordinated with "offline" meetings. The paradigm of learning is somewhat different than traditional "offline" or "onsite" meetings in that learning takes place over a period of 2 to 20 weeks, allowing the participating veterinarian to interact with instructors while applying the information in practice. Continual learning is encouraged as participants are allowed to participate in a course offered in sequential years. The successful online instructors tend to take advantage of electronic communications to encourage instructor-participant and participant-participant interactivity. The majority of course participants seek an additional challenge or greater interactivity in their continuing education experience; however, some veterinarians seek distance continuing education for practical reasons, including the ability to pursue additional education without leaving a solo practice, temporary or permanent physical disabilities, family considerations, or military service. Distance learning is a viable educational format, the role for which will evolve as technology and the base of experience with it expands.

    2011-01-01

    This qualitative study seeks to determine the nature of the instruction librarians provide to veterinary medical students at all 28 United States veterinary colleges. A secondary goal of the study was to determine in what ways and to what extent librarians participated in other instructional activities at their colleges. Over half of the librarians formally taught in one or more courses, predominantly in the first two years of the veterinary curriculum. One presentation per course was most common. Over half of the librarians interviewed stated that evidence-based veterinary medicine was taught at their colleges, and about half of these librarians collaborated with veterinary faculty in this instruction. Many librarians participated in orientation for first-year veterinary students. The librarians also taught instructional sessions for residents, interns, faculty, graduate students, and practicing veterinarians. This study found that librarians teach information literacy skills both formally and informally, but, in general, instruction by librarians was not well integrated into the curriculum. This study advances several recommendations to help veterinary students develop information literacy skills. These include: encourage veterinary faculty and administrators to collaborate more closely with librarians, incorporate a broader array of information literacy skills into assignments, and add a literature evaluation course to the curriculum.

    2012-07-01

    Full Text Available Homeopathy is an alternative medicine practice, which has been used for the past 200 years but, until now, scientific methods have not proven its effectiveness. The use of highly diluted natural substances based on the principal that similar heals similar is contrary to the scientific theories of the conventional medicine. In veterinary medicine homeopathic remedies are most frequently used for chronic conditions of small animals, but also their application in organic farming is increasing. Minimal number of clinical studies about the use of homeopathy in veterinary medicine has been published in scientific literature. The results of effectiveness are contradictory, which can be explained by being a consequence of different research methodologies. However, there is a significant inverse proportionality between the quality of research and results that approve of the use of homeopathy. In evidence based veterinary medicine scientific approach is fundamental for objective diagnostics and treatment prescription, and homeopathy is an excellent teaching model for possible methodological failures in scientific research. Key words: homeopathy, alternative medicine, evidence based veterinary medicine

    In this work we analyze how advanced Electron Beam Ion Sources (EBIS) can facilitate the progress of carbon therapy facilities. We will demonstrate that advanced ion sources enable operation of 2-nd generation ion beam therapy (IBT) accelerators. These new accelerator concepts with designs dedicated to IBT provide beams better suited for therapy and, are more cost efficient than contemporary IBT facilities. We will give a sort overview of the existing new IBT concepts and focus on those where ion source technology is the limiting factor. We will analyse whether this limitation can be overcome in the near future thanks to ongoing EBIS development.

    2012-06-05

    Ultrashort electron bunches with rms length of {approx} 1 femtosecond (fs) can be used to generate ultrashort x-ray pulses in FELs that may open up many new regimes in ultrafast sciences. It is also envisioned that ultrashort electron bunches may excite {approx}TeV/m wake fields for plasma wake field acceleration and high field physics studies. Recent success of using 20 pC electron beam to drive an x-ray FEL at LCLS has stimulated world-wide interests in using low charge beam (1 {approx} 20 pC) to generate ultrashort x-ray pulses (0.1 fs {approx} 10 fs) in FELs. Accurate measurement of the length (preferably the temporal profile) of the ultrashort electron bunch is essential for understanding the physics associated with the bunch compression and transportation. However, the shorter and shorter electron bunch greatly challenges the present beam diagnostic methods. In this paper we review the recent advances in the measurement of ultra-short electron bunches. We will focus on several techniques and their variants that provide the state-of-the-art temporal resolution. Methods to further improve the resolution of these techniques and the promise to break the 1 fs time barrier is discussed. We review recent advances in the measurement of ultrashort relativistic electron bunches. We will focus on several techniques and their variants that are capable of breaking the femtosecond time barrier in measurements of ultrashort bunches. Techniques for measuring beam longitudinal phase space as well as the x-ray pulse shape in an x-ray FEL are also discussed.

    Advance care planning (ACP) is an instrumental mechanism aimed at preserving patient autonomy. Numerous interventions have been proposed to facilitate the implementation of ACP; however, rates of completed advance directives (ADs) are universally low. Patient electronic portal messaging is a newer tool in patient-provider communication which has not been studied as a method to promote ACP. In this study, we hypothesized that the use of ACP-specific patient electronic messages would increase rates of AD completion in patients aged 65 years and older in an academic primary care practice. All primary care patients, aged 65+, who had previously enrolled in a patient electronic messaging system, within an academic primary care practice, were included for randomization. Two hundred patients were randomized to receive an electronic message. The primary outcome was the proportion of patients in each group who completed an AD, 3 months after intervention. Secondary outcomes included clinical utility of the completed ADs and proportion of patients who viewed their electronic messages. The intervention group completed an AD 5.5% of the time when compared to 2% in the control group (odds ratio 3.2 [1.6-6.3]). Up to 74.5% of patients opened their electronic messages. Among primary care patients aged 65 years and older, use of AD-specific electronic messaging statistically significantly increased the rate of AD completion, but the absolute number of completed AD remained relatively low. These data suggest that this valuable communication tool holds opportunities for further improvement. Older, frailer adults were more likely to complete an AD, and prompted directives were more likely to include a written expression of the individual's health-care values and preference.

    2008-01-01

    Under a U.S. Department of Energy program for radioisotope power systems, Lockheed Martin is developing an Engineering Unit of the Advanced Stirling Radioisotope Generator (ASRG). This is an advanced version of the previously reported SRG110 generator. The ASRG uses Advanced Stirling Convertors (ASCs) developed by Sunpower Incorporated under a NASA Research Announcement contract. The ASRG makes use of a Stirling controller based on power electronics that eliminates the tuning capacitors. The power electronics controller synchronizes dual-opposed convertors and maintains a fixed frequency operating point. The controller is single-fault tolerant and uses high-frequency pulse width modulation to create the sinusoidal currents that are nearly in phase with the piston velocity, eliminating the need for large series tuning capacitors. Sunpower supports this effort through an extension of their controller development intended for other applications. Glenn Research Center (GRC) supports this effort through system dynamic modeling, analysis and test support. The ASRG design arrived at a new baseline based on a system-level trade study and extensive feedback from mission planners on the necessity of single-fault tolerance. This paper presents the baseline design with an emphasis on the power electronics controller detailed design concept that will meet space mission requirements including single fault tolerance.

    Epilepsy is one of the most common chronic neurological diseases in veterinary practice. Magnetic resonance imaging (MRI) is regarded as an important diagnostic test to reach the diagnosis of idiopathic epilepsy. However, given that the diagnosis requires the exclusion of other differentials for seizures, the parameters for MRI examination should allow the detection of subtle lesions which may not be obvious with existing techniques. In addition, there are several differentials for idiopathic epilepsy in humans, for example some focal cortical dysplasias, which may only apparent with special sequences, imaging planes and/or particular techniques used in performing the MRI scan. As a result, there is a need to standardize MRI examination in veterinary patients with techniques that reliably diagnose subtle lesions, identify post-seizure changes, and which will allow for future identification of underlying causes of seizures not yet apparent in the veterinary literature.There is a need for a standardized veterinary epilepsy-specific MRI protocol which will facilitate more detailed examination of areas susceptible to generating and perpetuating seizures, is cost efficient, simple to perform and can be adapted for both low and high field scanners. Standardisation of imaging will improve clinical communication and uniformity of case definition between research studies. A 6-7 sequence epilepsy-specific MRI protocol for veterinary patients is proposed and further advanced MR and functional imaging is reviewed.

    Allergic diseases in animals are increasingly gaining importance in veterinary practice and as research models. For intradermal testing and allergen immunotherapy, a good knowledge of relevant allergens for the individual species is of great importance. Currently, the knowledge about relevant veterinary allergens is based on sensitization rates identified by intradermal testing or serum testing for allergen-specific IgE; crude extracts are the basis for most evaluations. Only a few studies provide evidence about the molecular structure of (particularly) dust mite, insect and mould allergens in dogs and horses, respectively. In those species, some major allergens differ from those in humans. This position paper summarizes the current knowledge about relevant allergens in dogs, cats and horses. © 2015 The Authors Allergy Published by John Wiley & Sons Ltd.

    The mission of the Association of American Veterinary Medical Colleges (AAVMC) is to advance the quality of academic veterinary medicine. Founded in 1966 by the 18 US colleges of veterinary medicine and 3 Canadian colleges of veterinary medicine then in existence, the AAVMC is celebrating 50 years of public service. Initially, the AAVMC comprised the Council of Deans, the Council of Educators, and the Council of Chairs. In 1984, the tri-cameral structure was abandoned and a new governing structure with a board of directors was created. In 1997, the AAVMC was incorporated in Washington, DC and a common application service was created. Matters such as workforce issues and the cost of veterinary medical education have persisted for decades. The AAVMC is a champion of diversity in the veterinary profession and a strong advocate for One Health. The AAVMC has adopted a global perspective as more international colleges of veterinary medicine have earned COE accreditation and become members.

    Buchanan, James W

    2013-03-01

    Throughout civilization, animals have played a pivotal role in the advancement of science and medicine. From as early as 400 BC when Hippocrates recognized that diseases had natural causes, the steadfast advances made by biologists, scientists, physicians and scholars were fueled by timely and important facts and information- much of it gained through animal observations that contributed importantly to understanding anatomy, physiology, and pathology. There have been many breakthroughs and historic developments. For example, William Harvey in the 16th and 17th centuries clarified the importance of the circulatory system, aided by observations in dogs and pigs, which helped to clarify and confirm his concepts. The nineteenth century witnessed advances in physical examination techniques including auscultation and percussion. These helped create the basis for enhanced proficiency in clinical cardiology. An explosion of technologic advances that followed in the 20th century have made possible sophisticated, accurate, and non-invasive diagnostics. This permitted rapid patient assessment, effective monitoring, the development of new cardiotonic drugs, clinical trials to assess efficacy, and multi-therapy strategies. The latter 20th century has marshaled a dizzying array of advances in medical genetics and molecular science, expanding the frontiers of etiologies and disease mechanisms in man, with important implications for animal health. Veterinary medicine has evolved during the last half century, from a trade designed to serve agrarian cultures, to a diverse profession supporting an array of career opportunities ranging from private, specialty practice, to highly organized, specialized medicine and subspecialty academic training programs in cardiology and allied disciplines.

    2015-08-01

    Nanomedicine is an interdisciplinary field that combines medicine, engineering, chemistry, biology and material sciences to improve disease management and can be especially valuable in oncology. Nanoparticle-based agents that possess functions such as tumor targeting, imaging and therapy are currently under intensive investigation. This review introduces the basic concept of nanomedicine and the classification of nanoparticles. Because of their favorable pharmacokinetics, tumor targeting properties, and resulting superior efficacy and toxicity profiles, nanoparticle-based agents can overcome several limitations associated with conventional diagnostic and therapeutic protocols in veterinary oncology. The two most important tumor targeting mechanisms (passive and active tumor targeting) and their dominating factors (i.e. shape, charge, size and nanoparticle surface display) are discussed. The review summarizes published clinical and preclinical studies that utilize different nanoformulations in veterinary oncology, as well as the application of nanoparticles for cancer diagnosis and imaging. The toxicology of various nanoformulations is also considered. Given the benefits of nanoformulations demonstrated in human medicine, nanoformulated drugs are likely to gain more traction in veterinary oncology. Published by Elsevier Ltd.

    2013-01-01

    As veterinary medical curricula evolve, the time dedicated to biomedical science teaching, as well as the role of biomedical science knowledge in veterinary education, has been scrutinized. Aside from being mandated by accrediting bodies, biomedical science knowledge plays an important role in developing clinical, diagnostic, and therapeutic reasoning skills in the application of clinical skills, in supporting evidence-based veterinary practice and life-long learning, and in advancing biomedical knowledge and comparative medicine. With an increasing volume and fast pace of change in biomedical knowledge, as well as increased demands on curricular time, there has been pressure to make biomedical science education efficient and relevant for veterinary medicine. This has lead to a shift in biomedical education from fact-based, teacher-centered and discipline-based teaching to applicable, student-centered, integrated teaching. This movement is supported by adult learning theories and is thought to enhance students' transference of biomedical science into their clinical practice. The importance of biomedical science in veterinary education and the theories of biomedical science learning will be discussed in this article. In addition, we will explore current advances in biomedical teaching methodologies that are aimed to maximize knowledge retention and application for clinical veterinary training and practice.

    We present the ASTRA Toolbox as an open platform for 3D image reconstruction in tomography. Most of the software tools that are currently used in electron tomography offer limited flexibility with respect to the geometrical parameters of the acquisition model and the algorithms used for reconstruction. The ASTRA Toolbox provides an extensive set of fast and flexible building blocks that can be used to develop advanced reconstruction algorithms, effectively removing these limitations. We demonstrate this flexibility, the resulting reconstruction quality, and the computational efficiency of this toolbox by a series of experiments, based on experimental dual-axis tilt series. - Highlights: • The ASTRA Toolbox is an open platform for 3D image reconstruction in tomography. • Advanced reconstruction algorithms can be prototyped using the fast and flexible building blocks. • This flexibility is demonstrated on a common use case: dual-axis tilt series reconstruction with prior knowledge. • The computational efficiency is validated on an experimentally measured tilt series.

    Roeder, Peter; Mariner, Jeffrey; Kock, Richard

    2013-08-05

    Rinderpest was a devastating disease of livestock responsible for continent-wide famine and poverty. Centuries of veterinary advances culminated in 2011 with the UN Food and Agriculture Organization and the World Organization for Animal Health declaring global eradication of rinderpest; only the second disease to be eradicated and the greatest veterinary achievement of our time. Conventional control measures, principally mass vaccination combined with zoosanitary procedures, led to substantial declines in the incidence of rinderpest. However, during the past decades, innovative strategies were deployed for the last mile to overcome diagnostic and surveillance challenges, unanticipated variations in virus pathogenicity, circulation of disease in wildlife populations and to service remote and nomadic communities in often-unstable states. This review provides an overview of these challenges, describes how they were overcome and identifies key factors for this success.

  6. Financing electronic waste recycling Californian households' willingness to pay advanced recycling fees.

    Science.gov (United States)

    Nixon, Hilary; Saphores, Jean-Daniel M

    2007-09-01

    The growth of electronic waste (e-waste) is of increasing concern because of its toxic content and low recycling rates. The e-waste recycling infrastructure needs to be developed, yet little is known about people's willingness to fund its expansion. This paper examines this issue based on a 2004 mail survey of California households. Using an ordered logit model, we find that age, income, beliefs about government and business roles, proximity to existing recycling facilities, community density, education, and environmental attitudes are significant factors for explaining people's willingness to pay an advanced recycling fee (ARF) for electronics. Most respondents are willing to support a 1% ARF. Our results suggest that policymakers should target middle-aged and older adults, improve programs in communities with existing recycling centers or in rural communities, and consider public-private partnerships for e-waste recycling programs.

    High resolution soft x-ray emission spectroscopy with high spatial resolution is used to study of the electronic structure and characterize advanced materials: high-Tc superconductors, transition metal compounds, porous silicon, solid-solid buried interfaces and hard materials. In high-Tc, the main attention is focused on the analysis of oxygen-cation interactions and the determination of the location of impurity atoms. In transition metal compounds the participation of different electronic states of constitute atoms in the valence band is analyzed and correctness of LDA band structure calculations is estimated. For CuFeO2 an unusual mutual position of the Cu3d and Fe3d bands was found which is attributed to strong electron-electron correlations. In porous silicon the local structure of silicon atoms is found to depend on the type of doping of the initial Si wafer. Solid-solid buried interfaces in thin semiconducting films irradiated by eximer laser are investigated. For the hard materials boron-carbonitride a structure consisting of hexagonal lattice planes of carbon and boron nitride is proposed.

    Holistic veterinary medicine treats the whole patient including all physical and behavioral signs. The root cause of disease is treated at the same time as accompanying clinical signs. Herbal and nutritional supplements can help support tissue healing and proper organ functioning, thereby reducing the tendency of disease progression over time. Proper selection of homeopathic remedies is based on detailed evaluation of clinical signs. Herbal medicines are selected based on organ(s) affected and the physiologic nature of the imbalance. Many herbal and nutraceutical companies provide support for veterinarians, assisting with proper formula selection, dosing, drug interactions, and contraindications. Copyright © 2014 Elsevier Inc.

    While most hospitals have adopted electronic health records (EHRs), we know little about whether hospitals use EHRs in advanced ways that are critical to improving outcomes, and whether hospitals with fewer resources - small, rural, safety-net - are keeping up. Using 2008-2015 American Hospital Association Information Technology Supplement survey data, we measured "basic" and "comprehensive" EHR adoption among hospitals to provide the latest national numbers. We then used new supplement questions to assess advanced use of EHRs and EHR data for performance measurement and patient engagement functions. To assess a digital "advanced use" divide, we ran logistic regression models to identify hospital characteristics associated with high adoption in each advanced use domain. We found that 80.5% of hospitals adopted at least a basic EHR system, a 5.3 percentage point increase from 2014. Only 37.5% of hospitals adopted at least 8 (of 10) EHR data for performance measurement functions, and 41.7% of hospitals adopted at least 8 (of 10) patient engagement functions. Critical access hospitals were less likely to have adopted at least 8 performance measurement functions (odds ratio [OR] = 0.58; P Technology for Economic and Clinical Health Act resulted in widespread hospital EHR adoption, use of advanced EHR functions lags and a digital divide appears to be emerging, with critical-access hospitals in particular lagging behind. This is concerning, because EHR-enabled performance measurement and patient engagement are key contributors to improving hospital performance. Hospital EHR adoption is widespread and many hospitals are using EHRs to support performance measurement and patient engagement. However, this is not happening across all hospitals.

    Over the past 30 years, China has been suffering from negative environmental impacts from distempered waste electrical and electronic equipments (WEEE) recycling activities. For the purpose of environmental protection and resource reusing, China made a great effort to improve WEEE recycling. This article reviews progresses of three major fields in the development of China's WEEE recycling industry: legal system, formal recycling system, and advanced integrated process. Related laws concerning electronic waste (e-waste) management and renewable resource recycling are analyzed from aspects of improvements and loopholes. The outcomes and challenges for existing formal recycling systems are also discussed. The advantage and deficiency related to advanced integrated recycling processes for typical e-wastes are evaluated respectively. Finally, in order to achieve high disposal rates of WEEE, high-quantify separation of different materials in WEEE and high added value final products produced by separated materials from WEEE, an idea of integrated WEEE recycling system is proposed to point future development of WEEE recycling industry. © 2012 American Chemical Society

    The saliva of medicinal leeches, e.g., Hirudo medicinalis and Hirudo verbana commonly used in hirudotherapy, contains more than 100 bioactive substances with various therapeutic effects, including anticoagulant, vasodilator, thrombolytic, anti-inflammatory and anaesthetic properties. Recently, leeches have been used very successfully in veterinary medicine to treat many diseases of animals, especially dogs, cats and horses. The most common indications for the use of leeches are hip and elbow dysplasia, acute and chronic arthritis, diseases associated with inflammation of tendons, ligaments, and fascia, diseases of the vertebrae and the treatment of scars. Leech therapy is a painless procedure which takes an average of 30 to 120 minutes, the time being dependent on the size of the animal. All leeches used in medical procedures should originate only from certified biofarms. The maintenance of sterile conditions for the culture, transport and storage of medical leeches is very important to protect animals from microbial infections. Hirudotherapy is successfully used in veterinary medicine, especially when traditional treatment is not effective, the effects of treatment are too slow, or after surgery, when the tissues may be threatened by venous congestion.

    It is important for veterinary administrators to apply knowledge bases from other fields to their own unique administrative needs. For example, although some resources are written for business managers, the discussions of four key management competency areas, guidelines for mastering these skills, organizational assessment tools, and other self-help tools may provide interesting food-for-thought for veterinary administrators.(76) In developing their own administrative styles, administrators should seek to apply those principles that seem to intuitively fit with their personal research styles, work situations, managerial styles, administrative preferences, and unique organizational culture. Through strengthening their liaisons with community and university business programs, counseling agencies, employee assistance programs, and psychology researchers, administrators can continue to be exposed to and benefit from new paradigms for consideration in veterinary medical environments. Through these liaisons, the unique needs of veterinary medical environments are also communicated to individuals within the fields of psychology and business, thus stimulating new research that specifically targets veterinary medical environment leadership issues. Each field has unique contributions to help veterinary administrators work toward creating veterinary medical environments that are creative, energetic, visionary, pragmatic, and highly marketable in order to help administrators recruit and nurture the best and brightest veterinary researchers, teachers, and clinicians.

    To characterize availability of electronic health records (EHRs) at the primary practice locations of certified nurse midwives (CNMs), nurse practitioners (NPs), and physicians in California prior to the implementation of the state's Medicaid EHR incentive program. Cross-sectional mail surveys of samples of CNMs, NPs, and physicians who have active California licenses and reside in California. Descriptive statistics were calculated and multivariate regression analyses were estimated to identify characteristics associated with having an EHR. The following practice characteristics were included in the multivariate model: payer mix (% Medicaid), practice setting (hospital vs outpatient), and practice size. Variables for practitioner's age, sex, and practice location were also included. For both CNMs/NPs and physicians, practice size was the strongest predictor of EHR availability. Practicing in a large or mid-sized group was associated with higher odds of having a basic EHR or an advanced EHR. Having a high percentage of Medicaid patients was associated with lower odds of having an advanced EHR. Among physicians, but not CNMs/NPs, hospital-based practice was associated with higher odds of having an advanced EHR; being over age 45 years was associated with lower odds of having any EHR. The results suggest that prior to the launch of California's Medicaid EHR incentive program, similar characteristics predicted EHR availability among both CNMs/NPs and physicians, and that availability was concentrated among large practices with fewer Medicaid patients. Future studies should assess whether Medicaid and Medicare incentive payments attenuate these relationships.

    2006-12-31

    The overall goal of this project was to demonstrate a combination of advanced electron microscopy techniques that can be effectively used to identify and characterize individual particles and their sources. Specific techniques to be used include high-angle annular dark field scanning transmission electron microscopy (HAADF-STEM), STEM energy dispersive X-ray spectrometry (EDX), and energy-filtered TEM (EFTEM). A series of ambient PM{sub 2.5} samples were collected in communities in southwestern Detroit, MI (close to multiple combustion sources) and Steubenville, OH (close to several coal fired utility boilers). High-resolution TEM (HRTEM) -imaging showed a series of nano-metal particles including transition metals and elemental composition of individual particles in detail. Submicron and nano-particles with Al, Fe, Ti, Ca, U, V, Cr, Si, Ba, Mn, Ni, K and S were observed and characterized from the samples. Among the identified nano-particles, combinations of Al, Fe, Si, Ca and Ti nano-particles embedded in carbonaceous particles were observed most frequently. These particles showed very similar characteristics of ultrafine coal fly ash particles that were previously reported. By utilizing HAADF-STEM, STEM-EDX, and EF-TEM, this investigation was able to gain information on the size, morphology, structure, and elemental composition of individual nano-particles collected in Detroit and Steubenville. The results showed that the contributions of local combustion sources - including coal fired utilities - to ultrafine particle levels were significant. Although this combination of advanced electron microscopy techniques by itself can not identify source categories, these techniques can be utilized as complementary analytical tools that are capable of providing detailed information on individual particles.

    To propose measures for radiological protection of veterinary workers in Japan, X-ray exposure of workers in typical conditions in veterinary clinics was assessed. Dose rates of useful beam and scattered radiation, worker exposure doses at different stations, and effectiveness of protective clothing were determined using TLD and ion chambers. As precausions against radiation, the following practices are important: (1) use of suitable and properly maintained X-ray equipment, (2) proper selection of safe working stations, (3) use of protective clothing. Regulations are necessary to restrict the use of X-rays in the veterinary field. Because the use of X-rays in the veterinary field is not currently controlled by law, the above precautions are essential for minimizing exposure of veterinary staff. (author).

  4. Recent advances in the application of electron tomography to materials chemistry.

    2012-10-16

    Nowadays, tomography plays a central role in pureand applied science, in medicine, and in many branches of engineering and technology. It entails reconstructing the three-dimensional (3D) structure of an object from a tilt series of two-dimensional (2D) images. Its origin goes back to 1917, when Radon showed mathematically how a series of 2D projection images could be converted to the 3D structural one. Tomographic X-ray and positron scanning for 3D medical imaging, with a resolution of ∼1 mm, is now ubiquitous in major hospitals. Electron tomography, a relatively new chemical tool, with a resolution of ∼1 nm, has been recently adopted by materials chemists as an invaluable aid for the 3D study of the morphologies, spatially-discriminating chemical compositions, and defect properties of nanostructured materials. In this Account, we review the advances that have been made in facilitating the recording of the required series of 2D electron microscopic images and the subsequent process of 3D reconstruction of specimens that are vulnerable, to a greater or lesser degree, to electron beam damage. We describe how high-fidelity 3D tomograms may be obtained from relatively few 2D images by incorporating prior structural knowledge into the reconstruction process. In particular, we highlight the vital role of compressed sensing, a recently developed procedure well-known to information theorists that exploits ideas of image compression and "sparsity" (that the important image information can be captured in a reduced data set). We also touch upon another promising approach, "discrete" tomography, which builds into the reconstruction process a prior assumption that the object can be described in discrete terms, such as the number of constituent materials and their expected densities. Other advances made recently that we outline, such as the availability of aberration-corrected electron microscopes, electron wavelength monochromators, and sophisticated specimen goniometers

    Recent innovations in specimen preparation, data collection, and image processing have led to improved structure determination using single-particle electron cryomicroscopy (cryo-EM). Here we explore some of these advances to improve structures determined using electron cryotomography (cryo-ET) and sub-tomogram averaging. We implement a new three-dimensional model for the contrast transfer function, and use this in a regularized likelihood optimization algorithm as implemented in the RELION program. Using direct electron detector data, we apply both single-particle analysis and sub-tomogram averaging to analyze radiation-induced movements of the specimen. As in single-particle cryo-EM, we find that significant sample movements occur during tomographic data acquisition, and that these movements are substantially reduced through the use of ultrastable gold substrates. We obtain a sub-nanometer resolution structure of the hepatitis B capsid, and show that reducing radiation-induced specimen movement may be central to attempts at further improving tomogram quality and resolution.

    2016-09-01

    Internationally, forensic medicine and pathology are increasingly recognized as an important aspect of work done by veterinary clinicians and veterinary pathologists. In this article, a forensic veterinary clinician, a forensic veterinary pathologist in private practice, and a forensic veterinary pathologist at a veterinary school discuss the interactions among veterinary clinicians, veterinary pathologists, and law enforcement agencies and how future interactions can be improved. The focus is on the United Kingdom, but many of the principles, challenges, and suggestions are applicable to other jurisdictions. Clinicians and pathologists require forensic training to enable them to apply their veterinary knowledge to suspected cases of animal abuse and to subsequently present their findings and conclusions to a court of law in a concise, professional, and unbiased manner, and some opportunities for such advanced training in the United Kingdom are indicated. It is important that forensic veterinary clinicians and pathologists interact in an unbiased and collegial manner to answer the questions posed by courts of law. Opportunities for improved training, communication, and interaction among forensic veterinarians, forensic scientists, and law enforcement are discussed. © The Author(s) 2016.

    Tablet computers offer a new method of information management in veterinary medical education. With the tablet computer, students can annotate class notes using electronic ink, search for keywords, and convert handwriting to text as needed. Additional electronic learning resources, such as medical dictionaries and electronic textbooks, can be readily available. Eleven first-year veterinary students purchased tablet computers and participated in an investigation of their working methods and perceptions of the tablet computer as an educational tool. Most students found the technology useful. The small size and portability of the tablet allowed easy transport and use in a variety of environments. Most students adapted to electronic notetaking by the second week of classes; negative experiences with the tablet centered on a failure to become comfortable with taking notes and navigating on the computer as opposed to writing and searching on paper. A few performance-related problems, including short battery life, were reported. Tablet software allowed conversion of faculty course notes from a variety of original formats, meaning that instructors could maintain their original methods of note preparation. Adopting a consistent naming convention for files helped students to locate the files on their computers, and smaller file sizes helped with computer performance. Collaboration between students was fostered by tablet use, which offers possibilities for future development of collaborative learning environments.

    There is limited convincing quantitative data on the export of used electronics from the United States (U.S.). Thus, we advance a methodology to quantify the export flows of whole units of used electronics from the U.S. using detailed export trade data, and demonstrate the methodology using laptops. Since used electronics are not explicitly identified in export trade data, we hypothesize that exports with a low unit value below a used-new threshold specific to a destination world region are used. The importance of using the most disaggregated trade data set available when resolving used and new goods is illustrated. Two detailed U.S. export trade data sets were combined to arrive at quantities and unit values for each port, mode of transport, month, trade partner country, and trade code. We add rigor to the determination of the used-new threshold by utilizing both the Neighborhood valley-emphasis method (NVEM) and published sales prices. This analysis found that 748 to 1199 thousand units of used laptops were exported from the U.S. in 2010, of which 78-81% are destined for non-OECD countries. Asia was found to be the largest destination of used laptop exports across all used-new threshold methods. Latin American and the Caribbean was the second largest recipient of these exports. North America and Europe also received used laptops from the U.S. Only a small fraction of used laptops was exported to Africa. However, these quantities are lower bound estimates because not all shipments of used laptops may be shipped using the proper laptop trade code. Still, this approach has the potential to give insight into the quantity and destinations of the exports if applied to all used electronics product types across a series of years.

    PET/CT is an advanced imaging modality that is becoming more commonly used in veterinary medicine. It is most commonly used to image patients with cancer, and the most frequently used radiopharmaceutical is F-18 FDG. F-18 FDG is a glucose analog that highlights areas of increased glucose metabolism on the PET images. CT images provide excellent anatomic depiction and aid in interpretation of the PET data. Many types of cancer are hypermetabolic on PET/CT scans, but normal structures and areas of inflammation are also hypermetabolic, so knowledge of normal imaging and cytologic or histopathologic evaluation of lesions is essential.

    Over the past decade, the federal government has mandated healthcare providers to incorporate electronic health records into practice by 2015. This technological update in healthcare documentation has generated a need for advanced practice RN programs to incorporate information technology into education. The National Organization of Nurse Practitioner Faculties created core competencies to guide program standards for advanced practice RN education. One core competency is Technology and Information Literacy. Educational programs are moving toward the utilization of electronic clinical tracking systems to capture students' clinical encounter data. The purpose of this integrative review was to evaluate current research on advanced practice RN students' documentation of clinical encounters utilizing electronic clinical tracking systems to meet advanced practice RN curriculum outcome goals in information technology as defined by the National Organization of Nurse Practitioner Faculties. The state of the science depicts student' and faculty attitudes, preferences, opinions, and data collections of students' clinical encounters. Although electronic clinical tracking systems were utilized to track students' clinical encounters, these systems have not been evaluated for meeting information technology core competency standards. Educational programs are utilizing electronic clinical tracking systems with limited evidence-based literature evaluating the ability of these systems to meet the core competencies in advanced practice RN programs.

    2007-01-01

    The articles collected in this book cover a wide range of materials with extraordinary superconducting and magnetic properties. For many of the materials studied, strong electronic correlations provide a link between these two phenomena which were long thought to be highly antagonistic. Both the progress in our understanding of fundamental physical processes and the advances made towards the development of devices are reported here. The materials studied come in a variety of forms and shapes from bulk to epitaxial films, nano- and heterostructures down to those involving single molecules and double quantum dots. In some cases the structuring serves the study of bulk properties. More often it is the change of these properties with nanostructuring and the properties of different materials in close proximity with each other that are of key interest because of possible application of these materials or heterostructures to quantum computing and spintronics.

    Supramolecular organic electronics rests on the use of bottom-up chemical self-assembly processes in order to design conducting components on the 5-100 nm scale. The challenges in this field are both the construction of 1D-nanostructures displaying optimized transport properties and their precise connections to electrodes. The present Research News highlights important advances in such materials regarding their electrical performances, from semiconductors to organic metals, but also regarding their processability. In particular, by externally controlling light-responsive supramolecular polymerization processes, and by using appropriate methods of casting with an applied electric field, it becomes possible to pre-determine the accurate positioning of organic interconnects within patterned nano-circuitry. These strategies using external stimuli to obtain addressability, thus hold promising alternatives to other conducting materials such as carbon nanotubes for further technological applications in nanosciences.

    Rapid advances of high-throughput technologies and wide adoption of electronic health records (EHRs) have led to fast accumulation of -omic and EHR data. These voluminous complex data contain abundant information for precision medicine, and big data analytics can extract such knowledge to improve the quality of health care. In this article, we present -omic and EHR data characteristics, associated challenges, and data analytics including data pre-processing, mining, and modeling. To demonstrate how big data analytics enables precision medicine, we provide two case studies, including identifying disease biomarkers from multi-omic data and incorporating -omic information into EHR. Big data analytics is able to address -omic and EHR data challenges for paradigm shift towards precision medicine. Big data analytics makes sense of -omic and EHR data to improve healthcare outcome. It has long lasting societal impact.

    In the course and prognosis of colorectal cancer (CRC), early detection and treatment are essential factors. Fecal immunochemical tests (FITs) are currently the most commonly used non-invasive screening tests for CRC and premalignant (advanced) adenomas, however, with restricted sensitivity. We hypothesized that fecal volatile organic compounds (VOCs) may serve as a diagnostic biomarker of CRC and adenomas. In this proof of concept study, we aimed to assess disease-specific VOC smellprints in fecal gas to distinguish patients with CRC and advanced adenomas from healthy controls. Fecal samples of patients who were scheduled to undergo an elective colonoscopy were collected. An electronic nose (Cyranose 320) was used to measure VOC patterns in fecal gas from patients with histopathologically proven CRC, with advanced adenomas and from controls (no abnormalities seen at colonoscopy). Receiver operator characteristic curves and corresponding sensitivity and specificity for detection of CRC and advanced adenomas were calculated. A total of 157 stool samples (40 patients with CRC, 60 patients with advanced adenomas, and 57 healthy controls) were analyzed by electronic nose. Fecal VOC profiles of patients with CRC differed significantly from controls (area under curve ± 95%CI, p-value, sensitivity, specificity; 0.92 ± 0.03, advanced adenomas could be discriminated from controls (0.79 ± 0.04, electronic nose seems to hold promise as a novel screening tool for the (early) detection of advanced neoplasia and CRC. © 2013 UICC.

    This paper describes the development of a Micro/Mini Air Reconnaissance Vehicle for advanced sensors and electronics at NASA Langley Research Center over the last year. This vehicle is expected to have a total weight of less than four pounds, a design velocity of 40 mph, an endurance of 15-20 minutes, and a maximum range of 5km. The vehicle has wings that are simple to detach yet retain the correct alignment. The upper fuselage surface has a quick release hatch used to access the interior and also to mount the varying propulsion systems. The sensor suite developed for this vehicle consists of a Pitot-static measurement system for determining air speed, an absolute pressure measurement for determining altitude, magnetic direction measurement, and three orthogonal gyros to determine body angular rates. Swarming GPS-guidance and in-flight maneuvering is discussed, as well as design and installation of some other advance sensors like MEMS microphones, infrared cameras, GPS, humidity sensors, and an ultrasonic sonar sensor. Also low cost, small size, high performance control and navigation system for the Micro Air Vehicle is discussed. At the end, laboratory characterization of different sensors, motors, propellers, and batteries will be discussed.

    We report on an advanced in-situ electron-beam lithography technique based on high-resolution cathodoluminescence (CL) spectroscopy at low temperatures. The technique has been developed for the deterministic fabrication and quantitative evaluation of nanophotonic structures. It is of particular interest for the realization and optimization of non-classical light sources which require the pre-selection of single quantum dots (QDs) with very specific emission features. The two-step electron-beam lithography process comprises (a) the detailed optical study and selection of target QDs by means of CL-spectroscopy and (b) the precise retrieval of the locations and integration of target QDs into lithographically defined nanostructures. Our technology platform allows for a detailed pre-process determination of important optical and quantum optical properties of the QDs, such as the emission energies of excitonic complexes, the excitonic fine-structure splitting, the carrier dynamics, and the quantum nature of emission. In addition, it enables a direct and precise comparison of the optical properties of a single QD before and after integration which is very beneficial for the quantitative evaluation of cavity-enhanced quantum devices.

    An extensive set of time-resolved imaging experiments has been performed on rf-linac driven free-electron lasers (FELs) over the past few years. These experiments have addressed both micropulse and macropulse timescales on both the charged-particle beam and the wiggler/undulator outputs (spontaneous emission and lasing). A brief review of first measurements on photoinjecter micropulse elongation, submacropulse phase slew in drive lasers, submacropulse wavelength shifts in lasers, etc. is presented. This is followed by discussions of new measurements of 35-MeV electron beam micropulse bunch length (<10 ps) using optical transition radiation, some of the first single bend synchrotron radiation beam profile measurements at gamma <80, and comments on the low-jitter synchroscan streak camera tuner. These techniques will be further developed on the 200-650 MeV linac test stand at the Advanced Photon Source (APS) in the next few years. Such techniques should be adaptable to many of the present FEL designs and to some aspects of the next generation of light sources.

    For five decades, the semiconductor industry has distinguished itself by the rapid pace of improvement in miniaturization of electronics products-Moore's Law. Now, scaling hits a brick wall, a paradigm shift. The industry roadmaps recognized the scaling limitation and project that packaging technologies will meet further miniaturization needs or ak.a "More than Moore". This paper presents packaging technology trends and accelerated reliability testing methods currently being practiced. Then, it presents industry status on key advanced electronic packages, factors affecting accelerated solder joint reliability of area array packages, and IPC/JEDEC/Mil specifications for characterizations of assemblies under accelerated thermal and mechanical loading. Finally, it presents an examples demonstrating how Accelerated Testing and Analysis have been effectively employed in the development of complex spacecraft thereby reducing risk. Quantitative assessments necessarily involve the mathematics of probability and statistics. In addition, accelerated tests need to be designed which consider the desired risk posture and schedule for particular project. Such assessments relieve risks without imposing additional costs. and constraints that are not value added for a particular mission. Furthermore, in the course of development of complex systems, variances and defects will inevitably present themselves and require a decision concerning their disposition, necessitating quantitative assessments. In summary, this paper presents a comprehensive view point, from technology to systems, including the benefits and impact of accelerated testing in offsetting risk.

  9. Advancing the surgical implantation of electronic tags in fish: a gap analysis and research agenda based on a review of trends in intracoelomic tagging effects studies

    Early approaches to surgical implantation of electronic tags in fish were often through trial and error, however, in recent years there has been an interest in using scientific research to identify techniques and procedures that improve the outcome of surgical procedures and determine the effects of tagging on individuals. Here we summarize the trends in 108 peer-reviewed electronic tagging effect studies focused on intracoleomic implantation to determine opportunities for future research. To date, almost all of the studies have been conducted in freshwater, typically in laboratory environments, and have focused on biotelemetry devices. The majority of studies have focused on salmonids, cyprinids, ictalurids and centrarchids, with a regional bias towards North America, Europe and Australia. Most studies have focused on determining whether there is a negative effect of tagging relative to control fish, with proportionally fewer that have contrasted different aspects of the surgical procedure (e.g., methods of sterilization, incision location, wound closure material) that could advance the discipline. Many of these studies included routine endpoints such as mortality, growth, healing and tag retention, with fewer addressing sublethal measures such as swimming ability, predator avoidance, physiological costs, or fitness. Continued research is needed to further elevate the practice of electronic tag implantation in fish in order to ensure that the data generated are relevant to untagged conspecifics (i.e., no long-term behavioural or physiological consequences) and the surgical procedure does not impair the health and welfare status of the tagged fish. To that end, we advocate for i) rigorous controlled manipulations based on statistical designs that have adequate power, account for inter-individual variation, and include controls and shams, ii) studies that transcend the laboratory and the field with more studies in marine waters, iii) incorporation of knowledge and

    2005-01-01

    There is a vast array of learning tools and approaches to veterinary education, many tried and true, many innovative and with potential. Such new methods have come about partly from an increasing demand from both students and teachers to avoid methods of teaching and training that harm animals. The aim is to create the best quality education, ideally supported by validation of the efficacy of particular educational tools and approaches, while ensuring that animals are not used harmfully and that respect for animal life is engendered within the student. In this paper, we review tools and approaches that can be used in the teaching of veterinary students, tools and approaches that ensure the dignity and humane treatment of animals that all teachers and students must observe as the very ethos of the veterinary profession that they serve. Veterinary education has not always met, and still often does not meet, this essential criterion.

  15. One world of veterinary medicine.

    Science.gov (United States)

    King, L J

    2009-08-01

    The veterinary profession finds itself in the midst of a new world order. Today veterinarians are part of a world that is exquisitely interconnected culturally, economically, socially, and professionally. As a consequence, societal needs and expectations of the profession are more demanding, critical and far-reaching. Veterinarians must play important roles in five intersecting domains of work: public health, bio-medical research, global food safety and security, ecosystem health and the more traditional role of caring for animals. To be successful in this broad and complex range of services and activities, veterinarians must possess an expanded knowledge base, acquire new skills, and develop a new mindset that will ensure their success and excellence in all these domains. The veterinary profession is becoming more fragmented and specialised, and it needs to be brought back together by a single sphere of knowledge or discipline that can serve as an intellectual foundation. The concept of One World of Veterinary Medicine can do just that. With this mindset veterinarians will become better connected to the world around and gain new public recognition and esteem. To achieve this, a special commitment by academic veterinary medicine is, of course, essential. Veterinary schools must lead an educational transformation that reaffirms the social contract of veterinarians and works to align diverse sectors, build a global community, find a common purpose and expand the 21st Century veterinary portfolio of services, activities, and new possibilities.

  16. Governance, veterinary legislation and quality.

    2012-08-01

    This review of governance distinguishes between ends and means and, by highlighting the complexity and differing definitions of the concept, defines its scope and focuses discussion on its characteristics in order to establish an interrelationship between veterinary legislation and governance. Good governance must be backed by legislation, and good legislation must incorporate the principles and instruments of good governance. This article lists some of the main characteristics of governance and then reviews them in parallel with the methodology used to draft veterinary legislation, emphasising the importance of goal-setting and stakeholder participation. This article describes the criteria developed by the Veterinary Legislation Support Programme (VLSP) of the World Organisation for Animal Health (OIE) for assessing the quality of veterinary legislation. It then makes a comparison between the quality assurance process and the good governance process in order to demonstrate that the introduction and proper use of the tools for developing veterinary legislation offered by the OIE VLSP leads to a virtuous circle linking legislation with good governance. Ultimately, the most important point remains the implementation of legislation. Consequently, the author points out that satisfactory implementation relies not only on legislation that is technically and legally appropriate, acceptable, applicable, sustainable, correctly drafted, well thought through and designed for the long term, but also on the physical and legal capacity of official Veterinary Services to perform their administrative and enforcement duties, and on there being the means available for all those involved to discharge their responsibilities.

  17. Advanced electron microscopy of novel ferromagnetic materials and ferromagnet/oxide interfaces in magnetic tunnel junctions

    Science.gov (United States)

    Shi, Fengyuan

    We have studied novel ferromagnetic (FM) materials and FM electrode/tunnel barrier interfaces in magnetic tunnel junctions (MTJs) by advanced electron microscopy including scanning transmission electron microscopy (HRSTEM) and electron energy loss spectroscopy (EELS). MTJs are one of the prototypical spintronic devices, with applications in magnetic random access memory, sensors and read heads. The performance of MTJs depends on several factors, including the FM electrodes and the FM/tunnel barrier interfaces. Therefore, to realize the high performance of MTJs, we first need high quality ferromagnetic electrodes with high spin polarization. High-quality Fe3O4 and Fe4N electrodes with theoretically predicted -100% spin polarization were fabricated by various methods and investigated by HRSTEM and STEM EELS. The Fe3O4 and Fe4N thin films have low defect density and good crystallinity, but when integrated as electrodes in a MTJ, problems emerged. In a Fe4N/AlOx/Fe MTJ, the magnetoresistance was negative, but relatively small, due to a defective Fe 3O4 reaction layer formed at the Fe4N/tunnel barrier interface revealed by HRSTEM and EELS. The interfacial reaction layer was thin and discontinuous which made direct imaging difficult. Therefore, STEM EELS was used to map out the reaction layer. A Fe3O4 reaction layer was also found in a nominally symmetric CoFe/AlOx/CoFe MTJs after annealing, which also exhibited inverse TMR and a non-symmetric bias dependence. We also investigated the MTJs with the Heusler alloy Co2MnSi as one or both electrode and crystalline MgO as the tunnel barrier, which exhibit quite high TMR due to coherent tunneling. We showed that the Co2MnSi/MgO interface in these junctions is dominated by a configuration of a pure Mn plane bonded across the interface to O. This was the first observation of that interface termination. HRSTEM images also show that the fraction of MnMn/O interface termination increases with increasing Mn concentration in the CMS

  18. Further advances in electron-beam pattern generation technology for 180-nm masks

    The technology in use in today's mask shop may not be adequate to meet 180 nm production requirements. In particular, requirements for linewidth control, linewidth uniformity, and registration are tightening at a breakneck pace. In the past, incremental improvements to registration and linewidth have been adequate to keep pace with steadily evolving mask requirements. This paradigm of continuous incremental improvement is not longer a valid model. Mask writers are needed that can deliver a higher dose to support advanced resists for superior critical dimension (CD) control, write faster to compensate for shrinking device sizes, and incorporate advanced calibration and error control schemes to improve placement accuracy. This paper describes key electron-beam pattern generation activities necessary to meet 180 nm mask requirements. This includes testing and implementation of multipass graybeam to improve throughput at lower addresses without compromising lithography quality, a new resist and process capable of supporting dry etching, and a data path capable of supporting addressing to 10 nm. Multipass gray (MPG) writing strategy was introduced with the MEBES 4500S. The ability to deliver a 4X improvement in dose while improving throughput is a significant advantage over previous MEBES systems. Because MPG is used in conjunction with offset scan voting, improvements in registration performance and a reduction in butting of over 50 percent have been demonstrated. Some of the process improvements attributed to a high dose mask writer are also documented in this paper. CD uniformity improvements with ZEP 7000 and dry etch at a 720 nm nominal feature size and smaller are also discussed in some detail.

    Studies have shown that blended approaches combining e-learning with face-to-face training reduces costs whilst maintaining similar learning outcomes. The preferences in learning approach for healthcare providers to this new style of learning have not been comprehensively studied. The aim of this study is to evaluate the acceptability of blended learning to advanced resuscitation training. Participants taking part in the traditional and blended electronic advanced life support (e-ALS) courses were invited to complete a written evaluation of the course. Participants' views were captured on a 6-point Likert scale and in free text written comments covering the content, delivery and organisation of the course. Proportional-odds cumulative logit models were used to compare quantitative responses. Thematic analysis was used to synthesise qualitative feedback. 2848 participants from 31 course centres took part in the study (2008-2010). Candidates consistently scored content delivered face-to-face over the same content delivered over the e-learning platform. Candidates valued practical hands on training which included simulation highly. Within the e-ALS group, a common theme was a feeling of "time pressure" and they "preferred the face-to-face teaching". However, others felt that e-ALS "suited their learning style", was "good for those recertifying", and allowed candidates to "use the learning materials at their own pace". The e-ALS course was well received by most, but not all participants. The majority felt the e-learning module was beneficial. There was universal agreement that the face-to-face training was invaluable. Individual learning styles of the candidates affected their reaction to the course materials.

  1. Veterinary education as leader: which alternatives?

    Science.gov (United States)

    Waldau, Paul

    2007-01-01

    This article suggests that veterinary medicine has a leadership role to play in our society on ethical matters involving non-human animals. The article contrasts two trends within veterinary medicine; the first trend is a continuation of the avowedly utilitarian attitude toward non-humans that has its roots in Western veterinary medicine's eighteenth-century origins, and the second is the implicit view in veterinary practice that animals matter in and of themselves. Using the idea of alternatives in research and teaching, the article suggests that, in the years to come, veterinary medicine's answers to the relationships of these two trends will shape not only the soul of veterinary medicine, veterinary education, and the veterinary profession but, just as importantly, the larger society and culture themselves. This text is based on the keynote address delivered at the AAVMC Education Symposium in Washington, DC, on March 9, 2006, under the title "Ethical Issues Impacting Animal Use in Veterinary Medical Teaching."

    2007-01-01

    An advanced-type small, light, multi-functional electronic personal dosemeter has been developed using silicon semiconductor radiation detectors for dose management of workers at nuclear power plants and accelerator facilities. This dosemeter is 62 x 82 x 27 mm(3) in size and approximately 130 g in weight, which is capable of measuring personal gamma ray and neutron dose equivalents, Hp(10), simultaneously. The neutron dose equivalent can be obtained using two types of silicon semiconductors: a slow-neutron sensor (1 MeV). The slow neutron sensor is a 10 x 10 mm(2) p-type silicon on which a natural boron layer is deposited around an aluminium electrode. The fast neutron sensor is also a 10 x 10 mm(2) p-type silicon crystal on which an amorphous silicon hydride is deposited. The neutron energy response corresponding to the fluence-to-dose-equivalent conversion coefficient given by ICRP Publication 74 has been evaluated using a monoenergetic neutron source from 250 keV to 15 MeV at the Fast Neutron Laboratory of Tohoku University. As the result, the Hp(10) response to neutrons in the energy range of 250 keV and 4.4 MeV within +/-50% difference has been obtained.

    In this work a combination of advanced transmission electron microscopy and spectroscopy techniques enabled a statistically significant analysis of various types of few nanometer size oxides particles in Fe-14Cr-2W-0.3Ti-0.3Y2O3 ferritic steel. These methods include a scanning TEM with EDS and EFTEM coupled with EELS. In addition, principal component analysis was applied to the chemical maps obtained by EFTEM, which drastically improved the signal to noise ratio. Three types of particles were identified in a size range from 2 to 300 nm, namely Cr-Ti-O, Y-O and Y-Ti-O particles, with an average size of 33,16 and 8 nm, respectively. The Cr-Ti-O particles contain Y and Ti enriched zones, which were not observed previously. The EFTEM analysis showed that the titanium addition leads to formation of Y-Ti-O nano-particles, which constitute 84% of the oxides but also precipitation of larger Cr-Ti-O. The presence of small amount of Y-O particles indicated a not sufficient amount of Ti available for reaction during mechanical alloying or consolidation.

    Recruitment and activation of eosinophils have been studied intensely in asthma and other allergic diseases. Less is known about the infiltration and degranulation patterns of eosinophils in the tumor stroma. Seven cases of advanced gastric carcinomas were found to be massively infiltrated by eosinophils and studied by light and electron microscopy. Gastric carcinomas, despite having similar numbers of tissue eosinophils, exhibited markedly different degranulation patterns. In 2 cases, resting nondegranulating eosinophils were found. Piecemeal degranulation was the predominant mode of secretion from eosinophils localized within the tumor stroma in 4 cases. Eosinophil exocytosis and cytolysis were rarely observed. In 1 case, crystals morphologically similar to Charcot-Leyden crystals were observed at the extracellular level as well as in phagosomes of tissue macrophages, confirming active sequestrations of eosinophil Charcot-Leyden protein by macrophages in vivo. In the same case, eosinophils showed characteristic features of early and late apoptotic changes, such as condensed chromatin, focal dilatation of nuclear envelope, and preserved plasma membrane. Morphological association between apoptotic eosinophils and deposition of granules in the tumor stroma was found. Extracellular deposition of intact granules from apoptotic eosinophils was distinct from eosinophilic (necrotic) cytolysis, and has reported previously in experimental studies in vitro. To the knowledge of the authors, this case represents the first report of late apoptotic eosinophils that release their granules within the tumor stroma in a human gastric carcinoma.

    This volume represents the written account of the NATO Advanced Study Institute "Lower-Dimensional Systems and Molecular Electronics" held at Hotel Spetses, Spetses Island, Greece from 12 June to 23 June 1989. The goal of the Institute was to demonstrate the breadth of chemical and physical knowledge that has been acquired in the last 20 years in inorganic and organic crystals, polymers, and thin films, which exhibit phenomena of reduced dimensionality. The interest in these systems started in the late 1960's with lower-dimensional inorganic conductors, in the early 1970's with quasi-one-dimensional crystalline organic conductors. which by 1979 led to the first organic superconductors, and, in 1977, to the fITSt conducting polymers. The study of monolayer films (Langmuir-Blodgett films) had progressed since the 1930's, but reached a great upsurge in . the early 1980's. The pursuit of non-linear optical phenomena became increasingly popular in the early 1980's, as the attention turned from inorganic crystals t...

    2012-01-01

    The increased efficiency and quality constraints imposed on electrical energy systems have inspired a renewed research interest in the study of formal approaches to the analysis and control of power electronics converters. Switched systems represent a useful framework for modeling these converters and the peculiarities of their operating conditions and control goals justify the specific classification of “switched electronic systems”. Indeed, idealized switched models of power converters introduce problems not commonly encountered when analyzing generic switched models or non-switched electrical networks. In that sense the analysis of switched electronic systems represents a source for new ideas and benchmarks for switched and hybrid systems generally. Dynamics and Control of Switched Electronic Systems draws on the expertise of an international group of expert contributors to give an overview of recent advances in the modeling, simulation and control of switched electronic systems.

    Ergonomics is the application of a body of knowledge addressing the interactions between man and the total working environment, such as atmosphere, heat, light and sound, as well as all tools and equipment of the workplace. Work related musculoskeletal injuries, caused by poor posture, have been discussed in human dentistry for several years. Veterinary dentistry, as a relatively new specialty within veterinary medicine, should address the ergonomics of poor posture without further delay to prevent work-related injuries. The generalist, as well as the specialist and their technicians, are subject to various neck and back disorders if proper ergonomic recommendations are not followed. This review article highlights basic ergonomic design principles for illumination and posture in veterinary dentistry.

    Superconducting electron cyclotron resonance ion source with advance design in Lanzhou (SECRAL) is an 18-28 GHz fully superconducting electron cyclotron resonance (ECR) ion source dedicated for highly charged heavy ion beam production. SECRAL, with an innovative superconducting magnet structure of solenoid-inside-sextupole and at lower frequency and lower rf power operation, may open a new way for developing compact and reliable high performance superconducting ECR ion source. One of the recent highlights achieved at SECRAL is that some new record beam currents for very high charge states were produced by 18 GHz or 18+14.5 GHz double frequency heating, such as 1 e microA of (129)Xe(43+), 22 e microA of (209)Bi(41+), and 1.5 e microA of (209)Bi(50+). To further enhance the performance of SECRAL, a 24 GHz/7 kW gyrotron microwave generator was installed and SECRAL was tested at 24 GHz. Some promising and exciting results at 24 GHz with new record highly charged ion beam intensities were produced, such as 455 e microA of (129)Xe(27+) and 152 e microA of (129)Xe(30+), although the commissioning time was limited within 3-4 weeks and rf power only 3-4 kW. Bremsstrahlung measurements at 24 GHz show that x-ray is much stronger with higher rf frequency, higher rf power. and higher minimum mirror magnetic field (minimum B). Preliminary emittance measurements indicate that SECRAL emittance at 24 GHz is slightly higher that at 18 GHz. SECRAL has been put into routine operation at 18 GHz for heavy ion research facility in Lanzhou (HIRFL) accelerator complex since May 2007. The total operation beam time from SECRAL for HIRFL accelerator has been more than 2000 h, and (129)Xe(27+), (78)Kr(19+), (209)Bi(31+), and (58)Ni(19+) beams were delivered. All of these new developments, the latest results, and long-term operation for the accelerator have again demonstrated that SECRAL is one of the best in the performance of ECR ion source for highly charged heavy ion beam production

    Integrative veterinary medicine (IVM) describes the combination of complementary and alternative therapies with conventional care and is guided by the best available evidence. Veterinarians frequently encounter questions about complementary and alternative veterinary medicine (CAVM) in practice, and the general public has demonstrated increased interest in these areas for both human and animal health. Consequently, veterinary students should receive adequate exposure to the principles, theories, and current knowledge supporting or refuting such techniques. A proposed curriculum guideline would broadly introduce students to the objective evaluation of new veterinary treatments while increasing their preparation for responding to questions about IVM in clinical practice. Such a course should be evidence-based, unbiased, and unaffiliated with any particular CAVM advocacy or training group. All IVM courses require routine updating as new information becomes available. Controversies regarding IVM and CAVM must be addressed within the course and throughout the entire curriculum. Instructional honesty regarding the uncertainties in this emerging field is critical. Increased training of future veterinary professionals in IVM may produce an openness to new ideas that characterizes the scientific method and a willingness to pursue and incorporate evidence-based medicine in clinical practice with all therapies, including those presently regarded as integrative, complementary, or alternative.

    Lasers have been used in human dentistry since the 1960's. Lasers can provide a veterinary dentist access to difficult to reach areas with a relatively bloodless surgical field. Due to vaporization of nerve endings, human patients undergoing laser dental treatment reveal less pain compared to scalpel driven procedures. Dental applications for the commonly used lasers are discussed, as are special safety precautions. Many dental procedures enhanced by a carbon dioxide laser are covered. Future applications for the laser in veterinary dentistry are also discussed.

    Abnormal body temperature is a major indicator of disease; infrared thermography (IRT) can assess changes in body surface temperature quickly and remotely. This technology can be applied to a myriad of diseases of various etiologies across a wide range of host species in veterinary medicine. It is used to monitor the physiologic status of individual animals, such as measuring feed efficiency or diagnosing pregnancy. Infrared thermography has applications in the assessment of animal welfare, and has been used to detect soring in horses and monitor stress responses. This review addresses the variety of uses for IRT in veterinary medicine, including disease detection, physiologic monitoring, welfare assessment, and potential future applications.

    Fabrication of defect free EUV mask is one of the most critical roadblocks for implementing EUV lithography into semiconductor high volume manufacturing for 22nm half-pitch (HP) node and beyond. At the same time, development of quality assurance process for the defect free EUV mask is also another critical challenge we need to address before the mass production. Inspection tools act important role in quality assurance process to ensure the defect free EUV mask. We are currently evaluating two types of inspection system: optical inspection (OPI) system and electron beam inspection (EBI) system [1, 2]. While OPI system is sophisticated technology and has an advantage in throughput, EBI system is superior in sensitivity and extendability to even small pattern. We evaluated sensitivity of EBI system and found it could detect 25 nm defects on 88nm L/S pattern which is as small as target defect size for 23 nm Flash HP pattern in 2013 in 2009 ITRS lithography roadmap [2, 3]. EBI system is effective inspection tool even at this moment to detect such small defects on 88nm HP pattern, though there are still some challenges such as the slow throughput and the reliability. Therefore, EBI system can be used as bridge tool to compensate insufficient sensitivity of current inspection tools and improve EUV mask fabrication process to achieve the defect free EUV mask. In this paper, we will present the results of native pattern defects founded on large field 88nm HP pattern using advance EBI system. We will also classify those defects and propose some ideas to mitigate them and realize the defect free EUV mask, demonstrating the capability of EBI as bridge tool.

    The Advanced eLectron-PHoton fAcility (ALPHA) is a compact electron accelerator under construction and being commissioned at the Indiana University Center for Exploration of Energy and Matter (CEEM). In this thesis, we have studied the refurbished Cooler Injector Synchrotron (CIS) RF cavity using both the transmission line model and SUPERFISH simulation. Both low power and high power RF measurements have been carried out to characterize the cavity. Considering the performance limit of ferrite, we have designed a new ferrite loaded, co-axial quarter wave like cavity with similar structure but a more suitable ferrite material. We have also designed a traveling wave stripline kicker for fast extraction by POISSON and Microwave Studio. The strips geometry is trimmed to maximize the uniformity of the kicking field and match the impedance of the power cables. The time response simulation shows the kicker is fast enough for machine operation. The pulsed power supply requirement has also been specified. For the beam diagnosis in the longitudinal direction, we use a wideband Wall Gap Monitor (WGM) served in CIS. With proper shielding and amplification to get good WGM signal, we have characterized the injected and extracted beam signal in single pass commissioning, and also verified the debunching effect of the ALPHA storage ring. A modulation-demodulation signal processing method is developed to measure the current and longitudinal profile of injected beam. By scanning the dipole strength in the injection line, we have reconstructed the tomography of the longitudinal phase space of the LINAC beam. In the accumulation mode, ALPHA will be operated under a low energy and high current condition, where intra beam scattering (IBS) becomes a dominant effect on the beam emittance. A self consistent simulation, including IBS effect, gas scattering and linear coupling, has been carried out to calculate the emittance of the stored beam.

    For many years after its invention around 1796, homeopathy was widely used in people and later in animals. Over the intervening period (1796-2016) pharmacology emerged as a science from Materia Medica (medicinal materials) to become the mainstay of veterinary therapeutics. There remains today a much smaller, but significant, use of homeopathy by veterinary surgeons. Homeopathic products are sometimes administered when conventional drug therapies have not succeeded, but are also used as alternatives to scientifically based therapies and licensed products. The principles underlying the veterinary use of drug-based and homeopathic products are polar opposites; this provides the basis for comparison between them. This two-part review compares and contrasts the two treatment forms in respect of history, constituents, methods of preparation, known or postulated mechanisms underlying responses, the legal basis for use and scientific credibility in the 21st century. Part 1 begins with a consideration of why therapeutic products actually work or appear to do so. British Veterinary Association.

    Especially in developing countries, the profession of veterinary medicine is closely tied with agriculture and government economic development, the national structure of education, and national public health. Currently, the Chinese veterinary medical educational system and accreditation standards are distinctly different from those of some more developed countries, such as the United States, Japan, or the countries of the European Union. Chinese veterinary education is still closely based on traditional Chinese education approaches and standards, which has led to some deficiencies in the Chinese system. With the development of a stronger economy in China and the growing trend toward globalization, and particularly since China joined the World Trade Organization (WTO), some important questions about China's system of veterinary education are being raised: How can veterinary science develop more rapidly in China? How can it meet the needs of the growing Chinese society? How can China bring its veterinary medical practice more in line with that of other, more advanced countries? This article describes some of the realities of veterinary medical education in China, discusses several existing problems, and puts forward some ideas for possible reforms. It is hoped that by this means those outside China may gain insight into our veterinary education program and that this, in turn, will lead to helpful input from international educators and other professionals to help improve our programs.

    To determine if manual dexterity and visuospatial skills can be used to predict baseline laparoscopic surgery skills in veterinary students. Pilot study. Veterinary students (n = 45) from years 1-4 volunteered for this study. An hour-long electronic questionnaire was completed by participants. The first section was used to collect demographics and information about prior nonsurgical experiences. The second section included 3 tests of visuospatial skills, including the Purdue Visualization of Rotations Test, Mental Rotations Test, and Raven's Advanced Progressive Matrices Test. Multiple tests were administered to assess innate dexterity, including the grooved pegboard test, indirect and direct zigzag tracking tests, and the 3Dconnexion proficiency test. Each dexterity test was performed once with the left hand and once with the right hand. The order of task performance was randomized. Basic laparoscopic skills were assessed using the validated fundamentals of laparoscopic surgery (FLS) peg transfer task. There was an association between left-handed grooved pegboard scores (95% CI -10046.36 to -1636.53, P-value = .008) and left-handed indirect zigzag tracking task (95% CI -35.78 to -8.20, P-value = .003) with FLS peg transfer scores. Individuals who reported playing videogames achieved higher scores on the FLS peg transfer task than those without videogame experience (95% CI 583.59 to 3509.97, P-value = .007). The results of this study suggest that dexterity was a better predictor of baseline laparoscopic skills than visuospatial skills in veterinary students. © 2017 The American College of Veterinary Surgeons.

  6. From One Medicine to Two: The Evolving Relationship between Human and Veterinary Medicine in England, 1791-1835.

    Science.gov (United States)

    Woods, Abigail

    2017-01-01

    This article offers a novel perspective on the evolving identities and relationships of human medicine and veterinary medicine in England during the decades that followed the 1791 foundation of the London Veterinary College. Contrary to the impressions conveyed by both medical and veterinary historians, it reveals that veterinary medicine, as initially defined, taught and studied at the college, was not a domain apart from human medicine but rather was continuous with it. It then shows how this social, cultural, and epistemological continuity fractured over the period 1815 to 1835. Under the impetus of a movement for medical reform, veterinarians began to advance an alternative vision of their field as an autonomous, independent domain. They developed their own societies and journals and a uniquely veterinary epistemology that was rooted in the experiences of veterinary practice. In this way, "one medicine" became "two," and the professions began to assume their modern forms and relations.

    Full Text Available The discovery of hybridoma technology by Kohler and Milstein in 1975, heralded a new era in antibody research. Mouse hybridomas were the first reliable source of monoclonal antibodies. The generation of monoclonal antibodies from species other than rats and mice, has developed slowly over the last 30 years. The advent of antibody engineering and realization of the advantages of non murine antibodies has increased their relevance recently. However, in the area of veterinary parasitology, monoclonal antibodies are just beginning to fulfill the promises inherent in their great specificity for recognizing and selectively binding to antigens. This review describes the recent advances in the application of monoclonal antibodies for immunodiagnosis / prophylaxis and immunotherapy of parasitic diseases. [Vet. World 2011; 4(4.000: 183-188

    To describe the epidemiology of veterinary pharmaceutical-related exposures to children based on calls to a regional poison control center. A retrospective analysis of pediatric (≤19 years of age) exposures to pharmaceutical products intended for animal use, managed by a regional poison control center from 1999 through 2013, was conducted. Case narratives were reviewed and coded for exposure-related circumstances and intended species. Descriptive statistics were generated. From 1999 through 2013, the Central Ohio Poison Center received 1431 calls that related to a veterinary pharmaceutical exposure for children ≤19 years of age. Most of the pediatric calls (87.6%) involved children ≤5 years of age. Exploratory behavior was the most common exposure-related circumstance (61.4%) and ingestion accounted for the exposure route in 93% of cases. Substances commonly associated with exposures included: veterinary drugs without human equivalent (17.3%), antimicrobial agents (14.8%), and antiparasitics (14.6%). Based on substance and quantity, the majority of exposures (96.9%) were not expected to result in long-term or lasting health effects and were managed at home (94.1%). A total of 80 cases (5.6%) were referred to a health care facility, and 2 cases resulted in a moderate health effect. Children ≤5 years of age are most at risk for veterinary pharmaceutical-related exposures. Although most exposures do not result in a serious medical outcome, efforts to increase public awareness, appropriate product dispensing procedures, and attention to home storage practices may reduce the risk of veterinary pharmaceutical exposures to young children.

  9. Predicted reliability of aerospace electronics: Application of two advanced probabilistic concepts

    Science.gov (United States)

    Suhir, E.

    Two advanced probabilistic design-for-reliability (PDfR) concepts are addressed and discussed in application to the prediction, quantification and assurance of the aerospace electronics reliability: 1) Boltzmann-Arrhenius-Zhurkov (BAZ) model, which is an extension of the currently widely used Arrhenius model and, in combination with the exponential law of reliability, enables one to obtain a simple, easy-to-use and physically meaningful formula for the evaluation of the probability of failure (PoF) of a material or a device after the given time in operation at the given temperature and under the given stress (not necessarily mechanical), and 2) Extreme Value Distribution (EVD) technique that can be used to assess the number of repetitive loadings that result in the material/device degradation and eventually lead to its failure by closing, in a step-wise fashion, the gap between the bearing capacity (stress-free activation energy) of the material or the device and the demand (loading). It is shown that the material degradation (aging, damage accumulation, flaw propagation, etc.) can be viewed, when BAZ model is considered, as a Markovian process, and that the BAZ model can be obtained as the ultimate steady-state solution to the well-known Fokker-Planck equation in the theory of Markovian processes. It is shown also that the BAZ model addresses the worst, but a reasonably conservative, situation. It is suggested therefore that the transient period preceding the condition addressed by the steady-state BAZ model need not be accounted for in engineering evaluations. However, when there is an interest in understanding the transient degradation process, the obtained solution to the Fokker-Planck equation can be used for this purpose. As to the EVD concept, it attributes the degradation process to the accumulation of damages caused by a train of repetitive high-level loadings, while loadings of levels that are considerably lower than their extreme values do not contribute

  10. Recent advances in electronic structure theory and their influence on the accuracy of ab initio potential energy surfaces

    1989-01-01

    Recent advances in electronic structure theory and the availability of high speed vector processors have substantially increased the accuracy of ab initio potential energy surfaces. The recently developed atomic natural orbital approach for basis set contraction has reduced both the basis set incompleteness and superposition errors in molecular calculations. Furthermore, full CI calculations can often be used to calibrate a CASSCF/MRCI approach that quantitatively accounts for the valence correlation energy. These computational advances also provide a vehicle for systematically improving the calculations and for estimating the residual error in the calculations. Calculations on selected diatomic and triatomic systems will be used to illustrate the accuracy that currently can be achieved for molecular systems. In particular, the F + H2 yields HF + H potential energy hypersurface is used to illustrate the impact of these computational advances on the calculation of potential energy surfaces.

    2012-05-01

    Full Text Available Photosensitized electron-transfer processes of fullerenes hybridized with electron donating or other electron accepting molecules have been surveyed in this review on the basis of the recent results reported mainly from our laboratories. Fullerenes act as photo-sensitizing electron acceptors with respect to a wide variety of electron donors; in addition, fullerenes in the ground state also act as good electron acceptors in the presence of light-absorbing electron donors such as porphyrins. With single-wall carbon nanotubes (SWCNTs, the photoexcited fullerenes act as electron acceptor. In the case of triple fullerene/porphyrin/SWCNT architectures, the photoexcited porphyrins act as electron donors toward the fullerene and SWCNT. These mechanisms are rationalized with the molecular orbital considerations performed for these huge supramolecules. For the confirmation of the electron transfer processes, transient absorption methods have been used, in addition to time-resolved fluorescence spectral measurements. The kinetic data obtained in solution are found to be quite useful to predict the efficiencies of photovoltaic cells.

    2012-04-01

    Full Text Available Until the middle of the 19th century, very few references exist regarding the occurrence of animal diseases in Namibia. With the introduction of contagious bovine pleuropneumonia (CBPP in 1859, this picture changed completely and livestock owners implemented various forms of disease control in an effort to contain the spread of this disease and minimise its devastating effects. After the establishment of the colonial administration in 1884, the first animal disease legislation was introduced in 1887 and the first veterinarian, Dr Wilhelm Rickmann, arrived in 1894. CBPP and the outbreak of rinderpest in 1897 necessitated a greatly expanded veterinary infrastructure and the first veterinary laboratory was erected at Gammams near Windhoek in 1897. To prevent the spread of rinderpest, a veterinary cordon line was established, which was the very beginning of the Veterinary Cordon Fence as it is known today. After the First World War, a small but dedicated corps of veterinarians again built up an efficient animal health service in the following decades, with veterinary private practice developing from the mid–1950s. The veterinary profession organised itself in 1947 in the form of a veterinary association and, in 1984, legislation was passed to regulate the veterinary profession by the establishment of the Veterinary Council of Namibia. The outbreak of foot and mouth disease in 1961 was instrumental in the creation of an effective veterinary service, meeting international veterinary standards of quality and performance which are still maintained today.

    1990-01-01

    This paper reports on two new advancements in CCD technology. The first area of development has produced a special purpose CCD designed for ultra low-signal level imaging and spectroscopy applications that require sub-electron read noise floors. A nondestructive output circuit operating near its 1/f noise regime is clocked in a special manner to read a single pixel multiple times. Off-chip electronics average the multiple values, reducing the random noise by the square-root of the number of samples taken. Noise floors below 0.5 electrons rms are reported. The second development involves the design and performance of a high resolution imager of 4096 x 4096 pixels, the largest CCD manufactured in terms of pixel count. The device utilizes a 7.5-micron pixel fabricated with three-level poly-silicon to achieve high yield.

    To demonstrate achievement of ability-based outcomes through a structured review of electronic student portfolios in an advanced pharmacy practice experience (APPE) program. One hundred thirty-eight students produced electronic portfolios containing select work products from APPEs, including a self-assessment reflective essay that demonstrated achievement of course manual-specified ability-based outcomes. Through portfolio submissions, all students demonstrated the achievement of ability-based outcomes for providing pharmaceutical care, evaluating the literature, and managing the medication use system with patient case reports most frequently submitted. The rubric review of self-reflective essays addressed student learning through APPEs and continuing professional development plans. The electronic portfolio with reflective essay proved to be a useful vehicle to demonstrate achievement of ability-based outcomes.

  1. Free electron lasers and other advanced sources of light: Scientific research opportunities

    Science.gov (United States)

    1994-09-01

    The free electron laser uses a beam of relativistic electrons passing through a periodic, transverse magnetic field to produce coherent radiation. The advantages of these devices are: A resonance condition that involves the energy of the electron beam, the strength of the magnetic field, and the periodicity of the magnet determines the wavelength of the radiation. Because one medium, the electrons, provides the gain in all spectral regions, adjusting either the beam energy or the field strength tunes the wavelength easily and rapidly over a wide range. Waste energy leaves the medium as kinetic energy of the electrons at nearly the speed of light. Moreover, the lasting medium consists only of electrons in a vacuum, and it does not have the material damage or thermal lensing problems associated with ordinary lasers. Therefore, free electron lasers can achieve very high peak powers. The main disadvantages of the free electron laser are its size and cost. Because the free electron laser requires an electron accelerator with its associated shielding, it has not been a device that could be placed in an individual investigator's laboratory and be operated and maintained by graduate students whose primary expertise is in other areas of science. Because free electron lasers are currently used only in central facilities, their use in scientific research involves both the cost of the device, and the cost and inconvenience of maintaining a facility. Unlike synchrotrons, free electron lasers serve one user, or at most a few users, at any one time. The required electron beam energy increases with decreasing wavelength, and the cost and size of the accelerator as well as the cost and size of the magnetic structure increase with decreasing wavelength. In addition to energy requirements, the electron beam must meet other requirements for emittance, energy spread, and peak current that become more stringent at shorter wavelengths. The shortest wavelength reached by existing free

    2007-01-01

    A comprehensive survey containing 30 questions regarding racial, cultural, and ethnic issues was sent electronically to each of the member colleges within the Association of American Veterinary Colleges (AAVMC) during 2005. Responses were received from 25 of the 28 veterinary colleges in the United States and two foreign colleges. Most colleges had more than one respondent complete the survey. Since the respondents were not identified and were not uniform in regards to position within each college, some responses might have reflected the individual respondent's views rather than the college's actual situation or philosophy. The information gained from this survey demonstrates strong trends in attitudes to and practices with respect to diversity in US veterinary colleges. Three major areas were addressed in the survey-college and university environment and cultures, faculty and curriculum, and recruitment and retention of veterinary students from underrepresented minorities. In many instances, the survey confirmed a lack of knowledge about diversity issues at the respondents' institutions. These survey results will serve as a benchmark for gauging changes in the profession's racial, cultural, and ethnic demographics in the future and as a foundation upon which to build effective diversity programs.

    2009-03-01

    Toxoplasma gondii has a very wide intermediate host range and is thought to be able to infect all warm blooded animals. The parasite causes a spectrum of different diseases and clinical symptoms within the intermediate hosts and following infection most animals develop adaptive humoral and cell-mediated immune responses. The development of protective immunity to T. gondii following natural infection in many host species has led researchers to look at vaccination as a strategy to control disease, parasite multiplication and establishment in animal hosts. A range of different veterinary vaccines are required to help control T. gondii infection which include vaccines to prevent congenital toxoplasmosis, reduce or eliminate tissue cysts in meat producing animals and to prevent oocyst shedding in cats. In this paper we will discuss some of the history, challenges and progress in the development of veterinary vaccines against T. gondii.

    Full Text Available The veterinary practitioner has an ethical obligation to help alleviate animal pain. Although most veterinarians accept the fact that animals feel pain, still, postoperative pain relief is not a routine practice in all veterinary hospitals and clinics today. Nociception is a physiological process which involves transduction, transmission, modulation and perception of the noxious stimuli. Chemical mediators are important components of the nociceptive reflex and offer a target of pharmacologic modulation. Assessment of pain in animals is the most important step in the successful management of pain. Choosing appropriate method of pain control would depend upon the type of procedure followed, severity of pain and economic considerations for each individual circumstance. Our understanding of the pain in its manifestation, mechanisms, assessment and alleviation in animals is still although improving, limited. [Vet World 2009; 2(9.000: 360-363

    2013-01-01

    The teaching and assessment of professional behaviors and attitudes are important components of veterinary curricula. This article aims to outline some important considerations and concepts which will be useful for veterinary educators reviewing or developing this topic. A definition or framework of veterinary professionalism must be decided upon before educators can develop relevant learning outcomes. The interface between ethics and professionalism should be considered, and both clinicians and ethicists should deliver professionalism teaching. The influence of the hidden curriculum on student development as professionals should also be discussed during curriculum planning because it has the potential to undermine a formal curriculum of professionalism. There are several learning theories that have relevance to the teaching and learning of professionalism; situated learning theory, social cognitive theory, adult learning theory, reflective practice and experiential learning, and social constructivism must all be considered as a curriculum is designed. Delivery methods to teach professionalism are diverse, but the teaching of reflective skills and the use of early clinical experience to deliver valid learning opportunities are essential. Curricula should be longitudinal and integrated with other aspects of teaching and learning. Professionalism should also be assessed, and a wide range of methods have the potential to do so, including multisource feedback and portfolios. Validity, reliability, and feasibility are all important considerations. The above outlined approach to the teaching and assessment of professionalism will help ensure that institutions produce graduates who are ready for the workplace.

  10. Liver scintigraphy in veterinary medicine.

    2014-01-01

    The most common veterinary application of liver scintigraphy is for the diagnosis of portosystemic shunts (PSSs). There has been a continual evolution of nuclear medicine techniques for diagnosis of PSS, starting in the early 1980s. Currently, transplenic portal scintigraphy using pertechnetate or (99m)Tc-mebrofenin is the technique of choice. This technique provides both anatomical and functional information about the nature of the PSS, with high sensitivity and specificity. Hepatobiliary scintigraphy has also been used in veterinary medicine for the evaluation of liver function and biliary patency. Hepatobiliary scintigraphy provides information about biliary patency that complements finding in ultrasound, which may not be able to differentiate between biliary ductal dilation from previous obstruction vs current obstruction. Hepatocellular function can also be determined by deconvolutional analysis of hepatic uptake or by measuring the clearance of the radiopharmaceutical from the plasma. Plasma clearance of the radiopharmaceutical can be directly measured from serial plasma samples, as in the horse, or by measuring changes in cardiac blood pool activity by region of interest analysis of images. The objective of this paper is to present a summary of the reported applications of hepatobiliary scintigraphy in veterinary medicine. Copyright © 2014 Elsevier Inc. All rights reserved.

    Fast Wave (FW) heating and electron cyclotron heating (ECH) are used in the DIII-D tokamak to study plasmas with low applied torque and dominant electron heating characteristic of burning plasmas. FW heating via direct electron damping has reached the 2.5 MW level in high performance ELMy H-mode plasmas. In Advanced Inductive (AI) plasmas, core FW heating was found to be comparable to that of ECH, consistent with the excellent first-pass absorption of FWs predicted by ray-tracing models at high electron beta. FW heating at the ∼2 MW level to ELMy H-mode discharges in the ITER Baseline Scenario (IBS) showed unexpectedly strong absorption of FW power by injected neutral beam (NB) ions, indicated by significant enhancement of the D-D neutron rate, while the intended absorption on core electrons appeared rather weak. The AI and IBS discharges are compared in an effort to identify the causes of the different response to FWs.

    2008-06-01

    There is an international shortage of veterinary clinical pathologists in the workplace. Current trainees in veterinary clinical pathology may choose to pursue careers in academe, diagnostic laboratories, government health services, biopharmaceutical companies, or private practice. Academic training programs attempt to provide trainees with an exposure to several career choices. However, due to the proprietary nature of much of the work in the biopharmaceutical industry, trainees may not be fully informed regarding the nature of work for veterinary clinical pathologists and the myriad opportunities that await employment in the biopharmaceutical industry. The goals of this report are to provide trainees in veterinary clinical pathology and other laboratory personnel with an overview of the work-life of veterinary clinical pathologists employed in the biopharmaceutical industry, and to raise the profile of this career choice for those seeking to enter the workforce. Biographical sketches, job descriptions, and motivation for 3 successful veterinary clinical pathologists employed in the biopharmaceutical industry are provided. Current and past statistics for veterinary clinical pathologists employed in the biopharmaceutical industry are reviewed. An overview of the drug development process and involvement of veterinary clinical pathologists in the areas of discovery, lead optimization, and candidate evaluation are discussed. Additional duties for veterinary clinical pathologists employed in the biopharmaceutical industry include development of biomarkers and new technologies, service as scientific resources, diagnostic support services, and laboratory management responsibilities. There are numerous opportunities available for trainees in veterinary clinical pathology to pursue employment in the biopharmaceutical industry and enjoy challenging and rewarding careers.

    Robertson, Kristen M; Bowser, Jacquelyn E; Bernstein, Joshua; Aboul-Enein, Basil H

    The prevalence of diseases of foodborne and zoonotic origin in Arabic-speaking countries highlights the importance of collaboration between human and animal health professionals. However, accessibility of research and evidence-based practices in these countries is not well characterized. This brief report determines the availability of professional veterinary journals within the Arabic-speaking region. An electronic search using 6 databases assessed for publication period, activity status, and available languages incorporated all aspects of veterinary medicine and specialties. Among 29 veterinary journals identified, the oldest current publication originated 63 years ago, with 10 journals currently interrupted or ceased. All 19 currently active journals are available electronically as open access, with 8 also offered in paper format. Veterinary journals published within Arabic-speaking countries are predominantly produced in Egypt, Iraq, and Sudan. Electronic access is lacking compared with English-speaking countries, and there is a lack of journals with an Arabic-language option. The reasons associated with language options in veterinary publications are not immediately apparent, yet may highlight differences among public health, health education, and zoonotic professionals and the populations they serve. Veterinary journals in Arabic-speaking countries do not adequately represent the overall region and are limited in access. Further evaluation of regional culture and publisher preferences is indicated to identify new collaboration opportunities among health professionals and local stakeholders.

    Dixon, William H R; Kinnison, Tierney; May, Stephen A

    2017-11-01

    At a time where high levels of stress are reported in the veterinary profession, this study explores the challenges that veterinary graduates encounter when they enter general (first opinion) practice. Participants had written reflective accounts of their 'Most Puzzling Cases' for the postgraduate Professional Key Skills module of the Certificate in Advanced Veterinary Practice, offered by the Royal Veterinary College. Reasons that a case was puzzling, or became challenging, were thematically analysed. Fifteen summaries were analysed. Three core themes were identified: 'clinical reasoning', centred on the limitations of pattern recognition and the methods used to overcome this; the 'veterinary healthcare system', focusing on the need for continuity of care, time pressure and support in the transition to practice; and the 'owner', looking at the broader clinical skills needed to succeed in general practice. Clinical reasoning was raised as an issue; discussion of when pattern recognition is not appropriate and what to do in these cases was common. A lack of experience in general practice case types, and how to best operate in the resource-constrained environment in which they present, is the likely cause of this, suggesting that a greater focus on the primary care paradigm is needed within veterinary education. © British Veterinary Association (unless otherwise stated in the text of the article) 2017.

  19. [Regulatory requirements regarding cell-based medicinal products for human and veterinary use - a comparison].

    Science.gov (United States)

    Kuhlmann-Gottke, Johanna; Duchow, Karin

    2015-11-01

    At present, there is no separate regulatory framework for cell-based medicinal products (CBMP) for veterinary use at the European or German level. Current European and national regulations exclusively apply to the corresponding medicinal products for human use. An increasing number of requests for the regulatory classification of CBMP for veterinary use, such as allogeneic stem cell preparations and dendritic cell-based autologous tumour vaccines, and a rise in scientific advice for companies developing these products, illustrate the need for adequate legislation. Currently, advice is given and decisions are made on a case-by-case basis regarding the regulatory classification and authorisation requirements.Since some of the CBMP - in particular in the area of stem-cell products - are developed in parallel for human and veterinary use, there is an urgent need to create specific legal definitions, regulations, and guidelines for these complex innovative products in the veterinary sector as well. Otherwise, there is a risk that that the current legal grey area regarding veterinary medicinal products will impede therapeutic innovations in the long run. A harmonised EU-wide approach is desirable. Currently the European legislation on veterinary medicinal products is under revision. In this context, veterinary therapeutics based on allogeneic cells and tissues will be defined and regulated. Certainly, the legal framework does not have to be as comprehensive as for human CBMP; a leaner solution is conceivable, similar to the special provisions for advanced-therapy medicinal products laid down in the German Medicines Act.

    VetCompass Australia is veterinary medical records-based research coordinated with the global VetCompass endeavor to maximize its quality and effectiveness for Australian companion animals (cats, dogs, and horses). Bringing together all seven Australian veterinary schools, it is the first nationwide surveillance system collating clinical records on companion-animal diseases and treatments. VetCompass data service collects and aggregates real-time, clinical records for researchers to interrogate, delivering sustainable and cost-effective access to data from hundreds of veterinary practitioners nationwide. Analysis of these clinical records will reveal geographical and temporal trends in the prevalence of inherited and acquired diseases, identify frequently prescribed treatments, revolutionize clinical auditing, help the veterinary profession to rank research priorities, and assure evidence-based companion-animal curricula in veterinary schools. VetCompass Australia will progress in three phases: (1) roll-out of the VetCompass platform to harvest Australian veterinary clinical record data; (2) development and enrichment of the coding (data-presentation) platform; and (3) creation of a world-first, real-time surveillance interface with natural language processing (NLP) technology. The first of these three phases is described in the current article. Advances in the collection and sharing of records from numerous practices will enable veterinary professionals to deliver a vastly improved level of care for companion animals that will improve their quality of life.

    Full Text Available This article presents an overview on typical properties, technologies, and applications of liquid metal based flexible printed electronics. The core manufacturing material—room-temperature liquid metal, currently mainly represented by gallium and its alloys with the properties of excellent resistivity, enormous bendability, low adhesion, and large surface tension, was focused on in particular. In addition, a series of recently developed printing technologies spanning from personal electronic circuit printing (direct painting or writing, mechanical system printing, mask layer based printing, high-resolution nanoimprinting, etc. to 3D room temperature liquid metal printing is comprehensively reviewed. Applications of these planar or three-dimensional printing technologies and the related liquid metal alloy inks in making flexible electronics, such as electronical components, health care sensors, and other functional devices were discussed. The significantly different adhesions of liquid metal inks on various substrates under different oxidation degrees, weakness of circuits, difficulty of fabricating high-accuracy devices, and low rate of good product—all of which are challenges faced by current liquid metal flexible printed electronics—are discussed. Prospects for liquid metal flexible printed electronics to develop ending user electronics and more extensive applications in the future are given.

    Microbial fermentation process is often sensitive to even slight changes of conditions that may result in unacceptable end-product quality. Thus, the monitoring of the process is critical for discovering unfavorable deviations as early as possible and taking the appropriate measures. However, the use of traditional analytical techniques is often time-consuming and labor-intensive. In this sense, the most effective way of developing rapid, accurate and relatively economical method for quality assurance in microbial fermentation process is the use of novel chemical sensor systems. Electronic nose techniques have particular advantages in non-invasive monitoring of microbial fermentation process. Therefore, in this review, we present an overview of the most important contributions dealing with the quality control in microbial fermentation process using the electronic nose techniques. After a brief description of the fundamentals of the sensor techniques, some examples of potential applications of electronic nose techniques monitoring are provided, including the implementation of control strategies and the combination with other monitoring tools (i.e. sensor fusion). Finally, on the basis of the review, the electronic nose techniques are critically commented, and its strengths and weaknesses being highlighted. In addition, on the basis of the observed trends, we also propose the technical challenges and future outlook for the electronic nose techniques.

    Secondary batteries have become important for smart grid and electric vehicle applications, and massive effort has been dedicated to optimizing the current generation and improving their energy density. Multi‐electron chemistry has paved a new path for the breaking of the barriers that exist in traditional battery research and applications, and provided new ideas for developing new battery systems that meet energy density requirements. An in‐depth understanding of multi‐electron chemistries in terms of the charge transfer mechanisms occuring during their electrochemical processes is necessary and urgent for the modification of secondary battery materials and development of secondary battery systems. In this Review, multi‐electron chemistry for high energy density electrode materials and the corresponding secondary battery systems are discussed. Specifically, four battery systems based on multi‐electron reactions are classified in this review: lithium‐ and sodium‐ion batteries based on monovalent cations; rechargeable batteries based on the insertion of polyvalent cations beyond those of alkali metals; metal–air batteries, and Li–S batteries. It is noted that challenges still exist in the development of multi‐electron chemistries that must be overcome to meet the energy density requirements of different battery systems, and much effort has more effort to be devoted to this.

    2015-01-01

    Each year the Association of American Veterinary Medical Colleges (AAVMC) conducts a survey after the close of the Veterinary Medical College Application Service (VMCAS) application. The survey provides a glimpse into applicant behavior surrounding the veterinary school application process. Additional survey questions probe into applicant financial behaviors, use of financial products and services, and pet ownership. This article examines the 2013 survey data from applicants who successfully completed the application, with a focus on applicant financial literacy and behaviors. Data from the study revealed a disconnect between applicants' perception of their ability to deal with day-to-day finances and their actual financial behaviors, particularly for first-generation college student applicants and applicants who are racially/ethnically underrepresented in veterinary medicine (URVM). Many applicants were not able to accurately report the average veterinary school graduate's student debt level, which suggests the potential need for better education about the costs associated with attending veterinary school.

    Integrating renewable energy and distributed generations into the Smart Grid architecture requires power electronic (PE) for energy conversion. The key to reaching successful Smart Grid implementation is to develop interoperable, intelligent, and advanced PE technology that improves and accelerates the use of distributed energy resource systems. This report describes the simulation, design, and testing of a single-phase DC-to-AC inverter developed to operate in both islanded and utility-connected mode. It provides results on both the simulations and the experiments conducted, demonstrating the ability of the inverter to provide advanced control functions such as power flow and VAR/voltage regulation. This report also analyzes two different techniques used for digital signal processor (DSP) code generation. Initially, the DSP code was written in C programming language using Texas Instrument's Code Composer Studio. In a later stage of the research, the Simulink DSP toolbox was used to self-generate code for the DSP. The successful tests using Simulink self-generated DSP codes show promise for fast prototyping of PE controls.

    Over the last two decades, technological advancements in the field of proteomics have advanced our understanding of the complex biological systems of living organisms. Techniques based on mass spectrometry (MS) have emerged as powerful tools to contextualise existing genomic information and to create quantitative protein profiles from plasma, tissues or cell lines of various species. Proteomic approaches have been used increasingly in veterinary science to investigate biological processes responsible for growth, reproduction and pathological events. However, the adoption of proteomic approaches by veterinary investigators lags behind that of researchers in the human medical field. Furthermore, in contrast to human proteomics studies, interpretation of veterinary proteomic data is difficult due to the limited protein databases available for many animal species. This review article examines the current use of advanced proteomics techniques for evaluation of animal health and welfare and covers the current status of clinical veterinary proteomics research, including successful protein identification and data interpretation studies. It includes a description of an emerging tool, sequential window acquisition of all theoretical fragment ion mass spectra (SWATH-MS), available on selected mass spectrometry instruments. This newly developed data acquisition technique combines advantages of discovery and targeted proteomics approaches, and thus has the potential to advance the veterinary proteomics field by enhancing identification and reproducibility of proteomics data.

    Evaluation of canine renal biopsy tissue has generally relied on light microscopic (LM) evaluation of hematoxylin and eosin-stained sections ranging in thickness from 3 to 5 µm. Advanced modalities, such as transmission electron microscopy (TEM) and immunofluorescence (IF), have been used sporadically or retrospectively. Diagnostic algorithms of glomerular diseases have been extrapolated from the World Health Organization classification scheme for human glomerular disease. With the recent establishment of 2 veterinary nephropathology services that evaluate 3-µm sections with a panel of histochemical stains and routinely perform TEM and IF, a standardized objective species-specific approach for the diagnosis of canine glomerular disease was needed. Eight veterinary pathologists evaluated 114 parameters (lesions) in renal biopsy specimens from 89 dogs. Hierarchical cluster analysis of the data revealed 2 large categories of glomerular disease based on the presence or absence of immune complex deposition: The immune complex-mediated glomerulonephritis (ICGN) category included cases with histologic lesions of membranoproliferative or membranous patterns. The second category included control dogs and dogs with non-ICGN (glomerular amyloidosis or focal segmental glomerulosclerosis). Cluster analysis performed on only the LM parameters led to misdiagnosis of 22 of the 89 cases-that is, ICGN cases moved to the non-ICGN branch of the dendrogram or vice versa, thereby emphasizing the importance of advanced diagnostic modalities in the evaluation of canine glomerular disease. Salient LM, TEM, and IF features for each pattern of disease were identified, and a preliminary investigation of related clinicopathologic data was performed. © The Author(s) 2015.

    Here in this paper, we present recent results on ultrafast control and probing of strongly correlated-electron materials. We focus on magnetoresistive manganites, applying excitation and probing wavelengths that cover the mid-IR to the soft X-rays. In analogy with near-equilibrium filling and bandwidth control of phase transitions, our approach uses both visible and mid-IR pulses to stimulate the dynamics by exciting either charges across electronic bandgaps or specific vibrational resonances. Lastly, x-rays are used to unambiguously measure the microscopic electronic, orbital, and structural dynamics. Our experiments dissect and separate the nonequilibrium physics of these compounds, revealing the complex interplay and evolution of spin, lattice, charge, and orbital degrees of freedoms in the time domain.

    In single-particle cryo-electron microscopy (cryo-EM), molecules suspended in a thin aqueous layer are rapidly frozen and imaged at cryogenic temperature in the transmission electron microscope. From the random projection views, a three-dimensional image is reconstructed, enabling the structure of the molecule to be obtained. In this article I discuss technological progress over the past decade, which has, in my own field of study, culminated in the determination of ribosome structure at 2.5-Å resolution. I also discuss likely future improvements in methodology.

    Electron collisions with atoms, ions, molecules, and surfaces are critically important to the understanding and modeling of low-temperature plasmas (LTPs), and so in the development of technologies based on LTPs. Recent progress in obtaining experimental benchmark data and the development of highly sophisticated computational methods is highlighted. With the cesium-based diode-pumped alkali laser and remote plasma etching of Si3N4 as examples, we demonstrate how accurate and comprehensive datasets for electron collisions enable complex modeling of plasma-using technologies that empower our high-technology-based society.

    The limited number of oral vaccines currently approved for use in humans and veterinary species clearly illustrates that development of efficacious and safe oral vaccines has been a challenge not only for fish immunologists. The insufficient efficacy of oral vaccines is partly due to antigen breakdown in the harsh gastric environment, but also to the high tolerogenic gut environment and to inadequate vaccine design. In this review we discuss current approaches used to develop oral vaccines for mass vaccination of farmed fish species. Furthermore, using various examples from the human and veterinary vaccine development, we propose additional approaches to fish vaccine design also considering recent advances in fish mucosal immunology and novel molecular tools. Finally, we discuss the pros and cons of using the zebrafish as a pre-screening animal model to potentially speed up vaccine design and testing for aquaculture fish species.

    Full Text Available Recent advancements in the use of electronic-nose (e-nose devices to analyze human breath profiles for the presence of specific volatile metabolites, known as biomarkers or chemical bio-indicators of specific human diseases, metabolic disorders and the overall health status of individuals, are providing the potential for new noninvasive tools and techniques useful to point-of-care clinical disease diagnoses. This exciting new area of electronic disease detection and diagnosis promises to yield much faster and earlier detection of human diseases and disorders, allowing earlier, more effective treatments, resulting in more rapid patient recovery from various afflictions. E-nose devices are particularly suited for the field of disease diagnostics, because they are sensitive to a wide range of volatile organic compounds (VOCs and can effectively distinguish between different complex gaseous mixtures via analysis of electronic aroma sensor-array output profiles of volatile metabolites present in the human breath. This review provides a summary of some recent developments of electronic-nose technologies, particularly involving breath analysis, with the potential for providing many new diagnostic applications for the detection of specific human diseases associated with different organs in the body, detectable from e-nose analyses of aberrant disease-associated VOCs present in air expired from the lungs.

    2005-01-01

    Two-hundred-and-eighty-nine veterinary students from all four years of the University of Tennessee, College of Veterinary Medicine (UTCVM) were invited to complete the Derogatis Stress Profile (DSP)1 and an original Demographic Data Profile (DDP). The DSP assessed the students' current experiences of perceived stress, and the DDP was designed to gather information about students' academic year, their living situations, their financial situations, their interest area within the veterinary medical profession, and their current methods of coping with stress. These data were gathered as a baseline measure of veterinary medical students' perceived level of stress and quality of life. In an earlier study, data were also collected from faculty and staff about the perceived quality of the climate and culture of the veterinary college. The results of the DSP and DDP suggest that, although veterinary students at UTCVM do not experience significant levels of stress overall, they do report higher levels of subjective stress, time pressure, and depression than the general population. The more companion animals that veterinary students cared for in their personal lives, the more likely they were to report higher levels of perceived stress. Lastly, there were significant differences between genders, with female veterinary students reporting higher levels of perceived stress than their male counterparts. The preliminary results of the climate and culture data suggest that faculty and staff of the veterinary college individually feel that they are cared for in the work environment and collectively believe that the college strives for excellence.

    Full Text Available After a short review of electron tomography techniques for materials science, this overview will cover some recent results on different shape memory and nanostructured metallic systems obtained by various three-dimensional (3D electron imaging techniques. In binary Ni–Ti, the 3D morphology and distribution of Ni4Ti3 precipitates are investigated by using FIB/SEM slice-and-view yielding 3D data stacks. Different quantification techniques will be presented including the principal ellipsoid for a given precipitate, shape classification following a Zingg scheme, particle distribution function, distance transform and water penetration. The latter is a novel approach to quantifying the expected matrix transformation in between the precipitates. The different samples investigated include a single crystal annealed with and without compression yielding layered and autocatalytic precipitation, respectively, and a polycrystal revealing different densities and sizes of the precipitates resulting in a multistage transformation process. Electron tomography was used to understand the interaction between focused ion beam-induced Frank loops and long dislocation structures in nanobeams of Al exhibiting special mechanical behaviour measured by on-chip deposition. Atomic resolution electron tomography is demonstrated on Ag nanoparticles in an Al matrix.

Multivariate statistical analysis (MSA) has been used to greatly improve the quality of elemental mapping data from core@shell nanoparticles. Results from a combination of spatially resolved microanalysis reveal the shell as Fe3O4 and show that the core is composed of oxidatively stable metallic Co. For the first time, a region of lower atom density between the particle core and shell has been observed and identified as a trapped carbon residue attributable to the organic capping agents present in the initial Co nanoparticle synthesis.Cobalt nanoparticles were synthesised via the thermal decomposition of Co2(CO)8 and were coated in iron oxide using Fe(CO)5.

    The interest of describing the ground state properties of a system in terms of one electron density (or its two spin components) is obvious, in particular due to the simple physical significance of this function. Recent experimental progress in diffraction made the measurement of charge and magnetization densities in crystalline solids possible, with an accuracy at least as good as theoretical accuracy. Theoretical developments of the many-body problem have proved the extreme importance of the one electron density function and presently, accurate methods of band structure determination become available. Parallel to the diffraction techniques, other domains of research (inelastic scattering, resonance, molecular spectroscopy) deal with quantities directly related to the one particle density. But the two types of studies do not interfere enough and one should obviously gain more information by interpreting all experiments that are related to the density together. It became necessary to have an International Sch...

    An assessment of the risk associated with accidents involving aircraft with carbon fiber composite structural components is examined. The individual fiber segments cause electrical and electronic equipment to fail under certain operating conditions. A Monte Carlo simulation model was used to computer the risk. Aircraft accidents with fire, release of carbon fiber material, entrainment of carbon fibers in a smoke plume transport of fibers downwind, transfer of some fibers/into the the interior of buildings, failures of electrical and electronic equipment, and economic impact of failures are discussed. Risk profiles were prepared for individual airports and the Nation. The vulnerability of electrical transmission equipment to carbon fiber incursion and aircraft accident total costs is investigated.

  20. Advances towards understanding and engineering direct interspecies electron transfer in anaerobic digestion.

    2017-11-01

    Direct interspecies electron transfer (DIET) is a recently discovered microbial syntrophy where cell-to-cell electron transfer occurs between syntrophic microbial species. DIET between bacteria and methanogenic archaea in anaerobic digestion can accelerate the syntrophic conversion of various reduced organic compounds to methane. DIET-based syntrophy can naturally occur in some anaerobic digester via conductive pili, however, can be engineered via the addition of various non-biological conductive materials. In recent years, research into understanding and engineering DIET-based syntrophy has emerged with the aim of improving methanogenesis kinetics in anaerobic digestion. This article presents a state-of-art review focusing on the fundamental mechanisms, key microbial players, the role of electrical conductivity, the effectiveness of various conductive additives, the significance of substrate characteristics and organic loading rates in promoting DIET in anaerobic digestion.

    2017-01-01

    Continuous Wave Nuclear Magnetic Resonance (CW-NMR) was a popular method for sample interrogation at the birth of magnetic resonance but has since been overlooked by most in favor of the now more popular pulsed techniques. CW-NMR requires relatively simple electronics although, for most designs, the execution is critical to the successful implementation and sensitivity of the system. For decades there have been reports in the literature from academic groups showing the potential of magnetic r...

    Cobalt nanoparticles were synthesised via the thermal decomposition of Co2(CO)8 and were coated in iron oxide using Fe(CO)5. While previous work focused on the subsequent thermal alloying of these nanoparticles, this study fully elucidates their composition and core@shell structure. State-of-the-art electron microscopy and statistical data processing enabled chemical mapping of individual particles through the acquisition of energy-filtered transmission electron microscopy (EFTEM) images and detailed electron energy loss spectroscopy (EELS) analysis. Multivariate statistical analysis (MSA) has been used to greatly improve the quality of elemental mapping data from core@shell nanoparticles. Results from a combination of spatially resolved microanalysis reveal the shell as Fe3O4 and show that the core is composed of oxidatively stable metallic Co. For the first time, a region of lower atom density between the particle core and shell has been observed and identified as a trapped carbon residue attributable to the organic capping agents present in the initial Co nanoparticle synthesis.

    The goals of this retrospective study of advanced mycosis fungoides are (1) to describe the indications of a combination of total skin electron beam and photon beam irradiation and (2) to analyze the results of total body or segmental photon irradiation for patients with extension beyond the skin. From January 1975 to December 1995, 45 patients with pathologically-confirmed mycosis fungoides or Sézary syndrome received a combination of TSEB and photon beam irradiation for advanced disease: 34 males and 11 females, mean age 61 years (range 27-87 years). The mean follow-up was 111 months (range 18-244 months, median 85 months). Whole-skin irradiation treatment to a depth of 3-5 mm with a 6-MeV electron beam was produced by a linear accelerator to a total dose of 24-30 Gy in 8-15 fractions, 3-4 times a week. In cases of thick plaques or tumors that were beyond the scope of low energy electron beams or for treating nodal areas (especially in the head and neck area or axilla involvement), regional irradiation (RRT) with Co-60 photon beams was followed by whole-skin electron beam irradiation (15 patients). In cases of diffuse erythrodermia, Sézary syndrome, nodal or visceral involvement, total body irradiation was delivered with a 25-MV photon beam using a split-course regimen to prevent hematological toxicity (22 patients). The first course consisted of 1.25 Gy delivered in ten fractions and 10 days. Subsequently, patients received TSEB. Four to 6 weeks after TSEB, they received a second course of 1.25 Gy. The cumulative TBI dose ranged from 2.5 to 3 Gy in about 3 months. Hemi-body irradiation (HB) with Co-60 (and a bolus) was given in cases of multiple regional tumors with large and thick infiltration of the skin to a dose of 9-12 Gy (using fractions of 1-1.5 Gy/day) which, once flattened, were boosted with whole-skin electron beam therapy (8 patients). At 3 months, the overall response rate was 75% with 23/45 (51%) patients in complete response and 24% in partial

    Suzuki, Koichi; Kawamura, Hiroshi

    2004-11-01

    Research and development on advanced high heat flux cooling technology for electronic devices has been carried out as the Project of Fundamental Technology Development for Energy Conservation, promoted by the New Energy and Industrial Technology Development Organization of Japan (NEDO). Based on the microgravity experiments on boiling heat transfer, the following useful results have obtained for the cooling of electronic devices. In subcooled flow boiling in a small channel, heat flux increases considerably more than the ordinary critical heat flux with microbubble emission in transition boiling, and dry out of the heating surface is disturbed. Successful enhancement of heat transfer is achieved by a capillary effect from grooved surface dual subchannels on the liquid supply. The critical heat flux increases 30-40 percent more than for ordinary subchannels. A self-wetting mechanism has been proposed, following investigation of bubble behavior in pool boiling of binary mixtures under microgravity. Ideas and a new concept have been proposed for the design of future cooling system in power electronics.

    2000-01-01

    This study used the peer-reviewed biomedical literature to define the veterinary informatics knowledgebase and associated subspecialties, and assesses the level of activity in the field over the thirty-year period from 1966 through 1995. Grateful Med was used to search the MEDLINE bibliographic database for articles that shared one or more Medical Subject Headings (MeSH) keywords from the veterinary and medical informatics subject headings. Each of ninety-five MeSH medical informatics terms was assigned to one of twelve veterinary informatics subspecialties. The number of articles retrieved by each MeSH keyword and subspecialty was calculated. A total of 611 articles were retrieved, representing the contributions of 1,338 authors published in 153 journals. The field experienced slow growth over the twenty-year period from 1966 through 1985. In the following decade, the cumulative number of veterinary informatics articles almost tripled and the percentage of veterinary-related articles that included an informatics component increased almost two-and-one-half fold. Despite this recent growth, the number of veterinary-related articles with an informatics component has never exceeded 1% of either the veterinary or medical informatics literature over the past thirty years, and representation of veterinary subspecialties in the literature varied widely.

    2016-09-01

    Veterinary forensic pathology is emerging as a distinct discipline, and this special issue is a major step forward in establishing the scientific basis of the discipline. A forensic necropsy uses the same skill set needed for investigations of natural disease, but the analytical framework and purpose of forensic pathology differ significantly. The requirement of legal credibility and all that it entails distinguishes the forensic from routine diagnostic cases. Despite the extraordinary depth and breadth of knowledge afforded by their training, almost 75% of veterinary pathologists report that their training has not adequately prepared them to handle forensic cases. Many veterinary pathologists, however, are interested and willing to develop expertise in the discipline. Lessons learned from tragic examples of wrongful convictions in medical forensic pathology indicate that a solid foundation for the evolving discipline of veterinary forensic pathology requires a commitment to education, training, and certification. The overarching theme of this issue is that the forensic necropsy is just one aspect in the investigation of a case of suspected animal abuse or neglect. As veterinary pathologists, we must be aware of the roles filled by other veterinary forensic experts involved in these cases and how our findings are an integral part of an investigation. We hope that the outcome of this special issue of the journal is that veterinary pathologists begin to familiarize themselves with not only forensic pathology but also all aspects of veterinary forensic science. © The Author(s) 2016.

    The integration of 2D materials such as molybdenum disulphide (MoS2) with diamond (3D) was achieved by forming an heterojunction between these two materials and its electrical performance was studied experimentally. The device charactertics did show good rectifying nature when p-type single crystal diamond was integrated with n-type MoS2. These results are very encouraging indicating possible applications in semiconductor electronics, however further studies are required for a detailed understanding of the transport phenomena at the MoS2/diamond interface.

    Electronic cigarettes (e-cigs) are becoming increasingly popular but little is known about how e-cig users' transition between the different device types and what device characteristics and preferences may influence the transition. Four thousand four hundred twenty-one experienced e-cig users completed an online survey about their e-cig use, devices, and preferences. Participants included in analysis were ever cigarette smokers who used an e-cig at least 30 days in their lifetime and who reported the type of their first and current e-cig device and the nicotine concentration of their liquid. Analyses focused on transitions between "first generation" devices (same size as a cigarette with no button) and "advanced generation" devices (larger than a cigarette with a manual button) and differences between current users of each device type. Most e-cig users (n = 2603, 58.9%) began use with a first generation device, and of these users, 63.7% subsequently transitioned to current use of an advanced generation device. Among users who began use with an advanced generation device (n = 1818, 41.1%), only 5.7% transitioned to a first generation device. Seventy-seven percent of current advanced generation e-cig users switched to their current device in order to obtain a "more satisfying hit." Battery capabilities and liquid flavor choices also influenced device choice. E-cig users commonly begin use with a device shaped like a cigarette and transition to a larger device with a more powerful battery, a button for manual activation and a wider choice of liquid flavors. © The Author 2015.

    Ortega S, César

    2012-01-01

    This article analyzes curriculum offerings related to aquaculture and/or aquatic-animal health taught in veterinary medical schools or colleges in Mexico. The information database of the Mexican Association of Schools and Colleges of Veterinary Medicine and the Web sites of veterinary institutions indicate that 60% of veterinary colleges include courses related to aquaculture in their curriculum, but most of these are optional courses. There are few specialized continuing education programs or graduate level courses. There is also a lack of veterinary participation, in both public and private sectors, in aquatic-animal health. It is evident that there should be a greater involvement by the veterinary profession in Mexico's aquaculture to ensure food production in a safe and sustainable manner; to achieve this, veterinary medical institutions must include more aquaculture and aquatic-animal health courses in their curricula.

    2012-11-01

    Stereo transmission electron microscopy (TEM) provides a 3D impression of the microstructure in a thin TEM foil. It allows to perform depth and TEM foil thickness measurements and to decide whether a microstructural feature lies inside of a thin foil or on its surface. It allows appreciating the true three-dimensional nature of dislocation configurations. In the present study we first review some basic elements of classical stereo TEM. We then show how the method can be extended by working in the scanning transmission electron microscope (STEM) mode of a modern analytical 200 kV TEM equipped with a field emission gun (FEG TEM) and a high angle annular dark field (HAADF) detector. We combine two micrographs of a stereo pair into one anaglyph. When viewed with special colored glasses the anaglyph provides a direct and realistic 3D impression of the microstructure. Three examples are provided which demonstrate the potential of this extended stereo TEM technique: a single crystal Ni-base superalloy, a 9% Chromium tempered martensite ferritic steel and a NiTi shape memory alloy. We consider the effect of camera length, show how foil thicknesses can be measured, and discuss the depth of focus and surface effects. Copyright © 2012 Elsevier B.V. All rights reserved.

    Readiness of defect-free mask is one of the biggest challenges to insert extreme ultraviolet (EUV) lithography into semiconductor high volume manufacturing for 22nm half pitch (HP) node and beyond. According to ITRS roadmap updated in 2008, minimum size of defect needed to be removed is 25nm for 22nm HP node in 2013 [1]. It is necessary, therefore, to develop EUV mask pattern inspection tool being capable of detecting 25nm defect. Electron beam inspection (EBI) is one of promising tools which will be able to meet such a tight defect requirement. In this paper, we evaluated defect detection sensitivity of electron beam inspection (EBI) system developed by Hermes Microvision, Inc. (HMI) using 88nm half-pitch (HP) line-and-space (L/S) pattern and 128nm HP contact-hole (C/H) pattern EUV mask. We found the EBI system can detect 25nm defects. We, furthermore, fabricated 4 types of EUV mask structures: 1) w/ anti-reflective (AR) layer and w/ buffer layer, 2) w/ AR layer and w/o buffer layer, 3) w/o AR layer and w/ buffer layer, 4) w/o AR layer and w/o buffer layer. And the sensitivity and inspectability for the EBI were compared. It was observed that w/o AR layer structure introduce higher image contrast and lead to better inspectability, although there is no significant different in sensitivity.

  12. Self-assembly of silicon nanowires studied by advanced transmission electron microscopy

    Directory of Open Access Journals (Sweden)

    Marta Agati

    2017-02-01

    Full Text Available Scanning transmission electron microscopy (STEM was successfully applied to the analysis of silicon nanowires (SiNWs that were self-assembled during an inductively coupled plasma (ICP process. The ICP-synthesized SiNWs were found to present a Si–SiO2 core–shell structure and length varying from ≈100 nm to 2–3 μm. The shorter SiNWs (maximum length ≈300 nm were generally found to possess a nanoparticle at their tip. STEM energy dispersive X-ray (EDX spectroscopy combined with electron tomography performed on these nanostructures revealed that they contain iron, clearly demonstrating that the short ICP-synthesized SiNWs grew via an iron-catalyzed vapor–liquid–solid (VLS mechanism within the plasma reactor. Both the STEM tomography and STEM-EDX analysis contributed to gain further insight into the self-assembly process. In the long-term, this approach might be used to optimize the synthesis of VLS-grown SiNWs via ICP as a competitive technique to the well-established bottom-up approaches used for the production of thin SiNWs.

  13. Stress and Depression among Veterinary Medical Students.

    Killinger, Stacy L; Flanagan, Sean; Castine, Eleanor; Howard, Kimberly A S

    While existing literature suggests that professional students (e.g., medical, dental, law, nursing, etc.) experience high levels of stress and depression, the experiences of veterinary medical students have been less well examined. The purpose of this study was to explore the levels of stress and depression among veterinary medical students and to examine the relationship between these variables. Study participants were 1,245 veterinary medical students from North America. The findings provide support for the assertion that veterinary medical students experience high levels of stress and depression. Results also indicated that there is a correlation between stress and depression for veterinary medical students and that female students experience higher levels of stress and depression than their male counterparts.

    An important frontier in the administration of therapeutic drugs to veterinary species is the use of different polymers as drug delivery platforms. The usefulness of polymers as platforms for the administration of pharmaceutical and agricultural agents has been clearly recognized in the recent decades. The chemical versatility of polymers and the wide range of developed controlled-release strategies enhance the possibilities for the formulation of active molecules. In particular, the veterinary area offers opportunities for the development of novel controlled-release drug delivery technologies adapted to livestock or companion animal health needs. In some cases, it also allows to improve profitability in meat production or to meet the safety criteria related to drug residues. A number of factors affect the selection of polymers and subsequent properties of the controlled-release drug delivery system. However, their selection also dictates the release kinetics of the drug from the delivery system. Such choices are therefore crucial as they affect the success and potential of the delivery system for achieving the therapeutic goals of the veterinarian. It is the intention of this review to give an overview of the most relevant polymers, which are used or have been tested as drug delivery release rate modifiers in the veterinary field. The article highlights some recent developments focusing on their advantages and applications and analyzes the future direction of the scientific and technological advancements in this area. © 2013 John Wiley & Sons Ltd.

    Despite significant advances in both the understanding and the treatment of cancer, the disease remains one of high mortality and morbidity causes in all species. Increases in survival times in human cancer have increased significantly in the past 25 years but most of these increases have been through small incremental changes. For some cancers, e.g. pancreatic cancer, survival times have not increased significantly in over 100 years. In veterinary oncology, there have been major shifts in the management of cancer in companion animals. Increased availability of specialist centres, coupled with changing attitudes in owners and veterinarians, have meant improvements in veterinary cancer care borne from market pressures and increased awareness and understanding. In this review the changing face of cancer biology over the past 25 years will be examined, and the barriers to clinical progress in veterinary medicine considered. Finally, an optimistic view of the future will be presented with the prospect of greater control over this devastating disease. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Imaging technology is critical for adequate diagnosis and staging in human and veterinary oncology. Sensitive detection of lesions is necessary to determine appropriate local or systemic therapy and to monitor therapeutic results. New technology in digital radiography, ultrasound, and computed tomography (CT) scanning are now widely available in veterinary medicine. Advanced imaging with high-detail CT scans, magnetic resonance imaging (MRI), and positron-emission tomography (PET) are now available in academic centers and some private specialty practices. This review describes the current and future applications of these new imaging systems and modalities in veterinary oncology and how advanced imaging contributes to diagnosis, staging, and monitoring of cancers. The potential of molecular imaging for accurate, minimally invasive diagnosis and monitoring is discussed. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Full Text Available Over the past 10-15 years, significant advances have been made in the development and application of geographical information systems (GIS and remote sensing (RS. In veterinary sciences, particularly in veterinary parasitology, GIS and RS offer powerful means for disease mapping, ecological analysis and epidemiological surveillance and have become indispensable tools for processing, analysing and visualising spatial data. They can also significantly assist with the assessment of the distribution of health-relevant environmental factors via interpolation and modelling. In this review, we first summarize general aspects of GIS and RS, and emphasize the most important applications of these tools in veterinary parasitology, including recent advances in territorial sampling. Disease mapping, spatial statistics, including Bayesian inference, ecological analyses and epidemiological surveillance are summarized in the next section and illustrated with a set of figures. Finally, a set of conclusions is put forward.

    Beam dynamics issues were assessed for a new linear induction electron accelerator. Special attention was paid to equilibrium beam transport, possible emittance growth, and beam stability. Especially problematic would be high-frequency beam instabilities that could blur individual radiographic source spots, low-frequency beam motion that could cause pulse-to-pulse spot displacement, and emittance growth that could enlarge the source spots. Beam physics issues were examined through theoretical analysis and computer simulations, including particle-in cell (PIC) codes. Beam instabilities investigated included beam breakup (BBU), image displacement, diocotron, parametric envelope, ion hose, and the resistive wall instability. Beam corkscrew motion and emittance growth from beam mismatch were also studied. It was concluded that a beam with radiographic quality equivalent to the present accelerators at Los Alamos will result if the same engineering standards and construction details are upheld.

    Despite many decades of research on the effective development of clinical systems in medicine, the adoption of health information technology to improve patient care continues to be slow, especially in ambulatory settings. This applies to dentistry as well, a primary care discipline with approximately 137,000 practitioners in the United States. A critical reason for slow adoption is the poor usability of clinical systems, which makes it difficult for providers to navigate through the information and obtain an integrated view of patient data. In this study, we documented the cognitive processes and information management strategies used by dentists during a typical patient examination. The results will inform the design of a novel electronic dental record interface. We conducted a cognitive task analysis (CTA) study to observe ten general dentists (five general dentists and five general dental faculty members, each with more than two years of clinical experience) examining three simulated patient cases using a think-aloud protocol. Dentists first reviewed the patient's demographics, chief complaint, medical history and dental history to determine the general status of the patient. Subsequently, they proceeded to examine the patient's intraoral status using radiographs, intraoral images, hard tissue and periodontal tissue information. The results also identified dentists' patterns of navigation through patient's information and additional information needs during a typical clinician-patient encounter. This study reinforced the significance of applying cognitive engineering methods to inform the design of a clinical system. Second, applying CTA to a scenario closely simulating an actual patient encounter helped with capturing participants' knowledge states and decision-making when diagnosing and treating a patient. The resultant knowledge of dentists' patterns of information retrieval and review will significantly contribute to designing flexible and task

    The transition from veterinary student to member of the veterinary profession is known to be challenging. This study aimed to determine and compare the opinions of final year veterinary students and recent graduates on graduate attributes that ease this transition. The study was carried out across 3 veterinary schools in the United Kingdom. Paper based or electronic surveys were used. Final year students in the 3 schools were surveyed either electronically (school A) or on paper (schools B and C). Student cohort sizes were 112, 227 and 102 respectively. Recent graduates were contacted either at a reunion event (school A) or electronically from database records (school B and school C). Cohort sizes of contacted graduates were 80, 175 and 91 respectively. Respondents were asked to rate 42 individual attributes on a 5 point Likert scale. Focus groups with final year students and recent graduates and telephone interviews with recent graduates were carried out. Data were analysed by two researchers through a combination of manual coding and thematic analysis. Data were grouped into broad themes then sorted into narrower themes. Data were then searched for counter examples. Response rates for final year students were 34% (school A), 36% (school B) and 40% (school C). Response rates for recent graduates were 56% (school A), 20% (school B) and 11% (school C). There was a high level of agreement between the cohorts with respect to communication skills, problem solving and decision making skills, recognition of own limitations and the ability to cope with pressure all rated unanimously important or very important. Business acumen, knowledge of veterinary practice management and research skills were the 3 attributes ranked at the bottom of the list. Nine attributes were identified with a significantly different (p veterinary clinical knowledge, knowledge of veterinary public health and zoonotic issues, veterinary legislation and veterinary practice management, commitment to

    Development of superconducting undulator (SCU) technology continues at the Advanced Photon Source (APS). The experience of building and successful operating the first short-length, 16-mm period length superconducting undulator SCU0 paved the way for a 1-m long, 18-mm period device— SCU18-1— which has been in operation since May 2015. The APS SCU team has also built and tested a 1.5-m long, 21-mm period length undulator as a part of the LCLS SCU R&D program, aimed at demonstration of SCU technology availability for free electron lasers. This undulator successfully achieved all the requirements including a phase error of 5° RMS. Our team has recently completed one more 1-m long, 18-mm period length undulator— SCU18-2— that is replacing the SCU0. We are also working on a helical SCU for the APS. The status of these projects will be presented.

    At the Advanced Light Source (ALS), the "femtoslicing" beamline is in operation since 1999 for the production of x-ray synchrotron radiation pulses with femtosecond duration. The mechanism used for generating the short x-ray pulses induces at the same time temporary structures in the electron bunch longitudinal distribution with very short characteristic length. Such structures emit intense coherent synchrotron radiation (CSR) in the terahertz frequency range. This CSR, whose measured intensity is routinely used as a diagnostics for the tune-up of the femtoslicing experiments, represents a potential source of terahertz radiation with very interesting features. Several measurements have been performed for its characterization and in this paper an updated description of the experimental results and of their interpretation is presented.

    A 32-channel heterodyne radiometer has been developed for the measurement of electron cyclotron emission (ECE) on the experimental advanced superconducting tokamak (EAST). This system collects X-mode ECE radiation spanning a frequency range of 104-168 GHz, where the frequency coverage corresponds to a full radial coverage for the case with a toroidal magnetic field of 2.3 T. The frequency range is equally spaced every 2 GHz from 105.1 to 167.1 GHz with an RF bandwidth of ~500 MHz and the video bandwidth can be switched among 50, 100, 200, and 400 kHz. Design objectives and characterization of the system are presented in this paper. Preliminary results for plasma operation are also presented.

    Lung function has been evaluated in both health and disease states by techniques, such as pulmonary function tests, which generally study aggregate function. These decades old modalities have yielded a valuable understanding of global physiologic and pathophysiologic structure-to-function relationships. However, such approaches have reached their limits. They cannot meet the current and anticipated needs of new surgical and pharmaceutical treatments. 4-D CT can provide insights into regional lung function (ventilation and blood flow) and thus can provide information at an early stage of disease when intervention will have the greatest impact. Lung CT over the last decade has helped with further defining anatomic features in disease, but has lagged behind advances on the cellular and molecular front largely because of the failure to account for functional correlates to structural pathology. Commercially available CT scanners are now capable of volumetric data acquisition in a breath-hold and capable of multi-level slice acquisitions of the heart and lungs with a per slice scan aperture of 50 - 300 msec, allowing for regional blood flow measurements. Static, volumetric imaging of the lung is inadequate in that much of lung pathology is a dynamic phenomenon and, thus, is only detectable if the lung is imaged as air and blood are flowing. This paper review the methodologies and early physiologic findings associated with our measures of lung tissue properties coupled with regional ventilation and perfusion.

  7. Veterinary vaccines: alternatives to antibiotics?

    2008-12-01

    The prevention of infectious diseases of animals by vaccination has been routinely practiced for decades and has proved to be one of the most cost-effective methods of disease control. However, since the pioneering work of Pasteur in the 1880s, the composition of veterinary vaccines has changed very little from a conceptual perspective and this has, in turn, limited their application in areas such as the control of chronic infectious diseases. New technologies in the areas of vaccine formulation and delivery as well as our increased knowledge of disease pathogenesis and the host responses associated with protection from disease offer promising alternatives for vaccine formulation as well as targets for the prevention of bacterial disease. These new vaccines have the potential to lessen our reliance on antibiotics for disease control, but will only reach their full potential when used in combination with other intervention strategies.

    Toxicology is a vast subject. Animals are exposed to numerous drugs, household products, plants, chemicals, pesticides and venomous animals. In addition to the individual toxicity of the various potential poisons, there is also the question of individual response and, more importantly, of species differences in toxicity. This review serves to address some of the common questions asked when dealing with animals with possible poisoning, providing evidence where available. The role of emetics, activated charcoal and lipid infusion in the management of poisoning in animals, the toxic dose of chocolate, grapes and dried fruit in dogs, the use of antidotes in paracetamol poisoning, timing of antidotal therapy in ethylene glycol toxicosis and whether lilies are toxic to dogs are discussed. © 2015 British Small Animal Veterinary Association.

    As it matures, the field of animal rehabilitation is welcoming utilization of interventions that have proven efficacy in the specialty of physical therapy for human patients. More recently, manual therapy techniques have become more accepted. Range-of-motion and stretching techniques; mobilization or manipulation of soft tissues, peripheral joints, and the spine; neuromuscular facilitation techniques; techniques unique to osteopathy; chest physical therapy; manual lymphatic drainage techniques; and neural mobilization techniques are now commonly incorporated in clinical practice, and these interventions are more commonly cited in the veterinary literature. The following is a brief review of these manual therapy approaches including the goals, effects, indications, precautions, and contraindications. Copyright © 2014 Elsevier Inc. All rights reserved.

    2016-10-01

    Full Text Available This paper comprises a review of the rapidly expanding application of nanoscale mineral characterization methodology to the study of ore deposits. Utilising bismuth sulphosalt minerals from a reaction front in a skarn assemblage as an example, we illustrate how a complex problem in ore petrology, can be approached at scales down to that of single atoms. We demonstrate the interpretive opportunities that can be realised by doing this for other minerals within their petrogenetic contexts. From an area defined as Au-rich within a sulphosalt-sulphide assemblage, and using samples prepared on a Focused Ion Beam–Scanning Electron Microscopy (SEM platform, we identify mineral species and trace the evolution of their intergrowths down to the atomic scale. Our approach progresses from a petrographic and trace element study of a larger polished block, to high-resolution Transmission Electron Microscopy (TEM and High Angle Annular Dark Field (HAADF Scanning-TEM (STEM studies. Lattice-scale heterogeneity imaged in HAADF STEM mode is expressed by changes in composition of unit cell slabs followed by nanoparticle formation and their growth into “veins”. We report a progressive transition from sulphosalt species which host lattice-bound Au (neyite, lillianite homologues; Pb-Bi-sulphosalts, to those that cannot accept Au (aikinite. This transition acts as a crystal structural barrier for Au. Fine particles of native gold track this progression over the scale of several hundred microns, leading to Au enrichment at the reaction front defined by an increase in the Cu gradient (several wt %, and abrupt changes in sulphosalt speciation from Pb-Bi-sulphosalts to aikinite. Atom-scale resolution imaging in HAADF STEM mode allows for the direct visualisation of the three component slabs in the neyite crystal structure, one of the largest and complex sulphosalts of boxwork-type. We show for the first time the presence of aikinite nanoparticles a few nanometres in

    Animal abuse and domestic violence are linked issues, and pet ownership is reported to play a crucial role in the choice to leave an abusive situation. Although veterinarians witness the effects of abuse and violence over the course of their careers, they have limited training regarding these issues. One mechanism for educating veterinary students while providing a service for victims of domestic violence is the creation of partnerships between domestic violence shelters and veterinary schools. These extracurricular programs can provide both care for pets belonging to victims of domestic violence and an educational platform for student participants. The goals of this study were to determine the prevalence and characteristics of domestic violence shelter partnerships (DVSPs) at North American veterinary teaching hospitals and to determine whether the presence of a DVSP was associated with increased awareness among veterinary students regarding animal abuse and domestic violence. Nine of 33 veterinary schools surveyed described a DVSP program. Students at schools with DVSPs associated with their veterinary teaching hospitals were significantly more likely to indicate that their awareness of the link between animal abuse and domestic violence had increased during veterinary school. Most veterinary students reported that they felt poorly prepared to handle domestic violence and animal abuse issues in the workplace. This study indicates that extracurricular DVSPs are a viable means of educating veterinary students regarding domestic violence and animal abuse. A need for improved education on these topics in veterinary schools across North America is identified.

    An advanced electronic phase stepped interferometry (EPSI) system is described for quantitative out-of-plane displacement and surface topography measurements for NDE applications. Image processing algorithms were developed using novel techniques to extend the sensitivity of EPSI and provide near real-time measurement capability. EPSI is known to provide out-of-plane displacement and surface topography measurements on the order of 1/20-1/100 microns. Noise can be a limiting factor, however, and robust phase unwrapping, which is required, remains an open and active research area. A prototype EPSI system was developed and tested using simulated and real data sets of known displacement fields. A robust maximum-likelihood binary-tree (MLBT) phase unwrapping technique was developed, providing greater robustness in the presence of noise than standard techniques. In addition, the MLBT algorithm lends itself to efficient and fast parallel implementations for near-real time implementation. The use of these advanced algorithms improves the capabilities of existing EPSI techniques, providing more robustness and near real-time measurements. Results are provided for deformations in Ti-6Al-4V and Al2024-T3 aerospace materials.

    SECRAL (superconducting ECR ion source with advanced design in Lanzhou) ion source has been in routine operation for Heavy Ion Research Facility in Lanzhou (HIRFL) accelerator complex since May 2007. To further enhance the SECRAL performance in order to satisfy the increasing demand for intensive highly charged ion beams, 3-5 kW high power 24 GHz single frequency and 24 GHz +18 GHz double frequency with an aluminum plasma chamber were tested, and some exciting results were produced with quite a few new record highly charged ion beam intensities, such as (129)Xe(35+) of 64 eμA, (129)Xe(42+) of 3 eμA, (209)Bi(41+) of 50 eμA, (209)Bi(50+) of 4.3 eμA and (209)Bi(54+) of 0.2 eμA. In most cases SECRAL is operated at 18 GHz to deliver highly charged heavy ion beams for the HIRFL accelerator, only for those very high charge states and very heavy ion beams such as (209)Bi(36+) and (209)Bi(41+), SECRAL has been operated at 24 GHz. The total operation beam time provided by SECRAL up to July 2011 has exceeded 7720 hours. In this paper, the latest performance, development, and operation status of SECRAL ion source are presented. The latest results and reliable long-term operation for the HIRFL accelerator have demonstrated that SECRAL performance for production of highly charged heavy ion beams remains improving at higher RF power with optimized tuning.

  16. The need for veterinary nursing in Nigeria

    2011-06-01

    Full Text Available Traditionally, nursing care has been identified as an integral part of human medicine but is not well recognised in veterinary medicine as practised in Nigeria. In caring for human beings, a nurse is expected to have the fundamental understanding of disease aetiology, manifestations, diagnosis, manage-ment, rehabilitation, prevention and control. This is equally applicable to the care of animals. The role of veterinary nursing in veterinary medicine is significant considering the multitude of issues involved in the care of animals. The keeping of domestic animals is becoming popular and consequently the spread of infectious diseases from animals to human beings is on the increase. It is vital for human beings and animals to coexist in a healthy environment. The authors examine the importance of nursing care in veterinary medicine, the current situation in Nigeria, the role of veterinary nurses, the inter-professional approach to veterinary medicine, preparedness for the emergence of infectious diseases and career opportunities for veterinary nurses. This premise falls within the context of the ‘One Health’ concept.

    2003-01-01

    Veterinary clinical pharmacology encompasses all interactions between drugs and animals and applies basic and clinical knowledge to improve rational drug use and patient outcomes. Veterinary pharmacology instructors set educational goals and objectives that, when mastered by students, lead to improved animal health. The special needs of pharmacology instruction include establishing a functional interface between basic and clinical knowledge, managing a large quantity of information, and mastering quantitative skills essential to successful drug administration and analysis of drug action. In the present study, a survey was conducted to determine the extent to which veterinary pharmacology instructors utilize information technology (IT) in their teaching. Several IT categories were investigated, including Web-based instructional aids, stand-alone pharmacology software, interactive videoconferencing, databases, personal digital assistants (PDAs), and e-book applications. Currently IT plays a largely ancillary role in pharmacology instruction. IT use is being expanded primarily through the efforts of two veterinary professional pharmacology groups, the American College of Veterinary Clinical Pharmacology (ACVCP) and the American Academy of Veterinary Pharmacology and Therapeutics (AAVPT). The long-term outcome of improved IT use in pharmacology instruction should be to support the larger educational mission of active learning and problem solving. Creation of high-quality IT resources that promote this goal has the potential to improve veterinary pharmacology instruction within and across institutions.

  18. Veterinary and human vaccine evaluation methods

    Despite the universal importance of vaccines, approaches to human and veterinary vaccine evaluation differ markedly. For human vaccines, vaccine efficacy is the proportion of vaccinated individuals protected by the vaccine against a defined outcome under ideal conditions, whereas for veterinary vaccines the term is used for a range of measures of vaccine protection. The evaluation of vaccine effectiveness, vaccine protection assessed under routine programme conditions, is largely limited to human vaccines. Challenge studies under controlled conditions and sero-conversion studies are widely used when evaluating veterinary vaccines, whereas human vaccines are generally evaluated in terms of protection against natural challenge assessed in trials or post-marketing observational studies. Although challenge studies provide a standardized platform on which to compare different vaccines, they do not capture the variation that occurs under field conditions. Field studies of vaccine effectiveness are needed to assess the performance of a vaccination programme. However, if vaccination is performed without central co-ordination, as is often the case for veterinary vaccines, evaluation will be limited. This paper reviews approaches to veterinary vaccine evaluation in comparison to evaluation methods used for human vaccines. Foot-and-mouth disease has been used to illustrate the veterinary approach. Recommendations are made for standardization of terminology and for rigorous evaluation of veterinary vaccines. PMID:24741009

    The undergraduate teaching of veterinary parasitology in an African perspective is reviewed. Information was gathered from 8 of approximately 20 veterinary schools/faculties in Africa. In order to compare teaching in the different schools a standard questionnaire was designed for collecting data on different aspects of the curriculum, including the curriculum structure, the year(s) in which veterinary parasitology is taught, the contact hours allocated to teaching and the methods of teaching. The results of the eight faculties/schools reveal that veterinary parasitology is taught in a disciplinary approach allocating a total of 90-198 h to lectures (46-75%) and practicals 38-196 h (25-54%) during the full curriculum. There are considerable differences in structure of the curricula and methods of teaching undergraduate veterinary parasitology between the various schools/faculties. Availability of teaching staff and the cost of running practical classes are the most limiting factors in teaching of veterinary parasitology. There is a need to constantly review the curriculum of undergraduate veterinary parasitology and to standardise the materials and methods in light of new knowledge.

    Microbe-mineral interactions occur in diverse modern environments, from the deep sea and subsurface rocks to soils and surface aquatic environments. They may have played a central role in the geochemical cycling of major (e.g., C, Fe, Ca, Mn, S, P) and trace (e.g., Ni, Mo, As, Cr) elements over Earth's history. Such interactions include electron transfer at the microbe-mineral interface that left traces in the rock record. Geomicrobiology consists in studying interactions at these organic-mineral interfaces in modern samples and looking for traces of past microbe-mineral interactions recorded in ancient rocks. Specific tools are required to probe these interfaces and to understand the mechanisms of interaction between microbes and minerals from the scale of the biofilm to the nanometer scale. In this review, we focus on recent advances in electron microscopy, in particular in cryoelectron microscopy, and on a panel of electrochemical and synchrotron-based methods that have recently provided new understanding and imaging of the microbe-mineral interface, ultimately opening new fields to be explored.

    Optical lithography will be the dominant technique used for 180 nm generation production devices. With a reduced feature size on the wafer, 4X optical reduction, optical proximity correction (OPC), and phase shift lithography techniques, mask-related errors become even more critical to wafer yield. In addition, small feature sizes and lithography enhancement techniques require finer edge resolution. Clearly, new patten generation tools are needed for this generation of maskmaking requirements. Multipass gray (MPG) writing strategy was introduced with the MEBESR 4500S. The ability to deliver a 4X improvement in dose while improving throughput is a significant advantage over previous MEBES systems. Since MPG is used in conjunction with offset scan voting, reduction in butting of over 50% has been demonstrated with MPG. Higher doses are now possible with use of a multipass writing strategy and a brighter source. As a result, resists with higher contrast and process robustness can be used. A significant improvement in uniformity is noted with the new process, an essential step needed in meeting 180 nm requirements. Dry etch is essential to meet these new requirements and with sufficient process margin to be manufacturable. This paper describes the key electron-beam pattern generation technology necessary to meet the requirement of 180 nm masks, including a high dose field- emission gun and column capable of delivering 800 A/cm2; complete dynamic beam correction; a digital stage servo to provide stable, reproducible stage control under high acceleration conditions; a high speed data path to support 320 MHz beam blanking and a 10 nm data address. This paper also examines the improvements made to the MEBES platform and documents the resulting improvements and compares these results to the requirements for 180 nm masks.

    An electronic cigarette (e-cigarette) is a device used to mimic the experience of smoking tobacco cigarettes. Considering their growing popularity amongst adolescents, it is imperative that education surrounding e-cigarettes be provided. The purpose of this project is to describe the development and delivery of a pilot interactive presentation and survey tool by doctor of pharmacy (PharmD) candidates to gauge the use and understanding of e-cigarettes amongst teens. An interactive presentation providing information on e-cigarettes was created by a PharmD candidate, and presented to 357 high school students in Massachusetts and New Hampshire. An anonymous survey tool was administered after the presentation to evaluate students' perception, use, and knowledge of e-cigarettes. When asked which is safer, an e-cigarette or a tobacco cigarette, most students (84%) responded "neither," and most stated that they learned something new from the presentation. Of the 96% of students that indicated they had heard of e-cigarettes, 27% of them had tried one. PharmD candidates reported increased confidence in public speaking and preparation of patient-suitable material. This pilot project provided both education to adolescents and insight into their experience and understanding of the potential harms of e-cigarettes. Having a PharmD candidate deliver the presentation may have increased the students' level of comfort. An interactive, PharmD candidate-delivered presentation about e-cigarettes is an innovative method to both provide education about e-cigarettes, and ascertain information about knowledge and use in adolescents. Facilitating presentations like this could be successful in other settings or topics. Copyright © 2017 Elsevier Inc. All rights reserved.

    In Sweden 300 veterinary clinics have a license for x-ray diagnostics. Six of them also have a license for nuclear medicine. During 2005 eight clinics were inspected and the results show that the radiation protection in veterinary medicine can be improved. No clinic fulfilled the regulations of categorization of workplaces and workers (SSI FS 1998:3). Half of the clinics had no Swedish manual to the x-ray equipment and just as many had not performed the annual function check. Obviously, there is a need for more information to staff in veterinary medicine.

    Smith, Donald F

    2010-01-01

    This article is the first in a series of three to be published in the Journal of Veterinary Medical Education (JVME). These articles are abridged versions of six lectures that make up an elective course on the history of the veterinary profession in North America offered at Cornell University's College of Veterinary Medicine in spring 2010. The course was based in large part on an oral history collection titled "An Enduring Veterinary Legacy"(1) that captures interesting and relevant veterinary stories. The course was designed to increase awareness of the history of veterinary medicine as we approach the sesquicentennial of the American Veterinary Medical Association (AVMA) in 2013 and as we join with our international colleagues in marking the 250th anniversary of the establishment of the world's first veterinary college in Lyon, France, in 2011.(2) The overarching goal of this course and the articles is to record and also to share first-person stories that describe the development of veterinary education and the veterinary profession in North America from the mid-1860s to the present. In the process, it is hoped that this history will encourage respect, love, and admiration for the veterinary profession and an appreciation of veterinary medicine as a versatile profession. The articles are somewhat Cornell-centric because the lectures on which they are based were presented to Cornell students at their home institution. However, it is hoped that the events are representative of the broader American experience. For educators interested in the course itself, a brief synopsis and a summary of student evaluations for the first year of presentation is appended here and in subsequent articles in this series.

  10. The impact of AVMA COE's accreditation on veterinary medical education.

    Science.gov (United States)

    Hendricks, Joan C

    2012-01-01

    Point 1: the American Veterinary Medical Association Council on Education's (AVMA COE's) accreditation pro-cess is aimed at minimum training for entry-level veterinarians. This has a two-fold consequence: 1. The opportunity to discover the absolute minimum number of necessary resources is opened. While this is a threat to the standard model of veterinary education, it might have value if it is cost-efficient and students graduate with minimal or no debt. 2. There is no mechanism to measure training,research, or service programs above the minimum or beyond the entry level. Point 2: the implication of the minimum entry-level general standard is also two-fold: 1. We must measure performance above the mini-mum. A separate process is necessary (a) to develop and implement objective metrics and (b) to publicize superior achievement as opposed to minimal performance. 2. We must measure and publicize institutions or programs that advance the field beyond training entry-level veterinarians. Service, research, and training aimed at advancing the field, providing leadership, and improving public health and safety(One Health) require separate measurement and advocacy in order to obtain and justify the necessary resources. I conclude that in the absence of a new process by which to measure excellence, market forces will push the entire profession toward the most cost-effective method of providing minimal training for entry-level veterinarians. But what about the far more expensive goal of providing a global public good of which our profession is so proud?The public health and safety mission of veterinary medi-cine, including the entire One Health initiative, requires separate measurement in order to give objective metrics to the institutions and components of the profession committed to those goals to pursue vigorous advocacy and obtain or retain the necessary resources.

    2015-03-01

    Full Text Available Animal paleopathology is not a very well known scientific discipline within veterinary science, but it has great importance for historical and archaeological investigations. In this paper, authors attention is focused on the description of one of the most common findings on the skeletal remains of animals - osteoarthropathies. This review particularly emphasizes the description and classification of the most common pathological changes in synovial joints. The authors have provided their observations on the importance of joint diseases in paleopathology and veterinary medicine. Analysis of individual processes in the joints of the animals from the past may help in the understanding of diseases in modern veterinary medicine. Differential diagnosis was made a point of emphasis and discussion, so that this work could have practical significance for paleopathology and veterinary medicine

  17. Good veterinary governance: definition, measurement and challenges.

    Msellati, L; Commault, J; Dehove, A

    2012-08-01

    Good veterinary governance assumes the provision of veterinary services that are sustainably financed, universally available, and provided efficiently without waste or duplication, in a manner that is transparent and free of fraud or corruption. Good veterinary governance is a necessary condition for sustainable economic development insomuch as it promotes the effective delivery of services and improves the overall performance of animal health systems. This article defines governance in Veterinary Services and proposes a framework for its measurement. It also discusses the role of Veterinary Services and analyses the governance dimensions of the performance-assessment tools developed by the World Organisation for Animal Health (OIE). These tools (OIE PVS Tool and PVS Gap Analysis) track the performance of Veterinary Services across countries (a harmonised tool) and over time (the PVS Pathway). The article shows the usefulness of the OIE PVS Tool for measuring governance, but also points to two shortcomings, namely (i) the lack of clear outcome indicators, which is an impediment to a comprehensive assessment of the performance of Veterinary Services, and (ii) the lack of specific measures for assessing the extent of corruption within Veterinary Services and the extent to which demand for better governance is being strengthened within the animal health system. A discussion follows on the drivers of corruption and instruments for perception-based assessments of country governance and corruption. Similarly, the article introduces the concept of social accountability, which is an approach to enhancing government transparency and accountability, and shows how supply-side and demand-side mechanisms complement each other in improving the governance of service delivery. It further elaborates on two instruments--citizen report card surveys and grievance redress mechanisms--because of their wider relevance and their possible applications in many settings, including Veterinary

    As in other facets of medical science, the use of lasers in veterinary medicine is a relatively new phenomenon. Economic aspects of the profession as well as questionable returns on investment have limited laser applications primarily to the academic community, research institutions, and specialty practices. As technology improves and efficacy is proven, costs should decrease and allow further introduction of laser surgical and diagnostic devices into the mainstream of clinical veterinary medicine.

    Veterinarians are encouraged to use evidence to inform their practice, but it is unknown what resources (e.g. journals, electronic sources) are accessed by them globally. Understanding the key places veterinarians seek information can inform where new clinically relevant evidence should most effectively be placed. An international survey was conducted to gain understanding of how veterinary information is accessed by veterinarians worldwide. There were 2137 useable responses to the questionnaire from veterinarians in 78 countries. The majority of respondents (n = 1835/2137, 85.9%) undertook clinical work and worked in a high income country (n = 1576/1762, 89.4%). Respondents heard about the survey via national veterinary organisations or regulatory bodies (31.5%), online veterinary forums and websites (22.7%), regional, discipline-based or international veterinary organisations (22.7%) or by direct invitation from the researchers or via friends, colleagues or social media (7.6%). Clinicians and non-clinicians reportedly used journals most commonly (65.8%, n = 1207/1835; 75.6%, n = 216/286) followed by electronic resources (58.7%, n = 1077/1835; 55.9%, n = 160/286), respectively. Respondents listed a total of 518 journals and 567 electronic sources that they read. Differences in veterinarian preference for resources in developed, and developing countries, were found. The nominated journals most read were the Journal of the American Veterinary Medical Association (12.7% of nominations) for clinicians and the Veterinary Record (5.7%) for non-clinicians. The most accessed electronic resource reported was the Veterinary Information Network (25.6%) for clinicians and PubMed (7.4%) for non-clinicians. In conclusion, a wide array of journals and electronic resources appear to be accessed by veterinarians worldwide.

    A recent survey of European Colleges (European College of Equine Internal Medicine [ECEIM] and European College of Veterinary Surgeons [ECVS]) revealed the different strategies implemented by, and some of the challenges facing, European clinicians presented with cases of post operative ileus (POI). It was concluded that further comparative analysis of opinions, canvassed from additional colleges of equine veterinary specialism worldwide, would provide valuable additional insight into current POI knowledge on a more global scale. To report and compare the current strategies favoured by American veterinary specialists when managing POI in horses that underwent emergency colic surgery. Cross-sectional survey. Electronic invitations were sent to 814 Large Animal specialists, including 3 colleges: the American College of Veterinary Internal Medicine (ACVIM), American College of Veterinary Surgeons (ACVS) and the American College of Veterinary Emergency and Critical Care (ACVECC). The response rate was 14% (115/814). The majority of respondents (68%) reported an estimated prevalence range of POI of 0-20%. The presence of reflux on nasogastric intubation was the main criterion used to define POI. A lesion involving the small intestine was considered the main risk factor for POI. Anti-inflammatory drugs, intravenous (i.v.) fluids and antimicrobial drugs were the primary strategies used when managing POI. Flunixin meglumine and i.v. lidocaine were the drugs most commonly used in the treatment of horses with POI. Supplementary management strategies targeted mainly the prevention of post operative adhesions, infection and inflammation. There is a lack of consensus on the clinical definition of POI. Prospective and objective clinical assessment of the effectiveness of the different strategies contained within this and the European survey is necessary in order to identify a standardised approach to the management of equine POI. © 2015 EVJ Ltd.

    Watson, Elizabeth; Heng, Hock Gan

    2017-05-01

    Imaging studies are often of evidentiary value in medicolegal investigations involving animals and the role of the veterinary radiologist is to interpret those images for courts as an expert or opinion witness. With progressing interest in prosecuting animal crimes and strengthening of penalties for crimes against animals, the participation of veterinary radiologists in medicolegal investigations is expected to increase. Veterinary radiologists who are aware of radiographic and imaging signs that result in animal suffering, abuse, or neglect; knowledgeable in ways radiology and imaging may support cause of death determinations; conversant in postmortem imaging; comfortable discussing mechanisms and timing of blunt or sharp force and projectile trauma in imaging; and prepared to identify mimics of abuse can assist court participants in understanding imaging evidence. The goal of this commentary review is to familiarize veterinary radiologists with the forensic radiology and imaging literature and with the advantages and disadvantages of various imaging modalities utilized in forensic investigations. Another goal is to provide background information for future research studies in veterinary forensic radiology and imaging. © 2017 American College of Veterinary Radiology.

    Australian veterinary classrooms are increasingly diverse and their growing internal diversity is a result of migration and large numbers of international students. Graduates interact with other students and increasingly with clients whose attitudes, beliefs, values, and behaviors differ from their own. An understanding and respect for these differences has an impact on client communication and health care outcomes. The present study explored how students understand and are likely to deal with issues of cultural diversity in veterinary professional practice as well as the educational needs that students feel should be met in regard to preparation to engage productively with diversity in professional practice. The present study also explored the extent to which the rich diversity of the undergraduate student population constitutes an educational resource. A class of final-year veterinary students was invited to participate in a workshop exploring intercultural confidence in veterinary consultation. Twelve groups of six to eight students discussed a fictitious scenario involving a challenging clinical encounter with a client from a different culture. Students were reticent to see the scenario in terms of cultural difference, although they generally recognized that awareness of cultural issues in veterinary practice was important. They also tended to not see their own ethnicity as relevant to their practice. While some felt that veterinary practice should be culture blind, most recognized a need to orient to cultural difference and to respond sensitively. Their suggestions for curricular improvements to address these issues are also included.

  6. Utility of Electronic Medical record-based Fibrosis Scores in Predicting Advanced Cirrhosis in Patients with Hepatitic C Virus Infection.

    To determine whether advanced cirrhosis - defined by the detection of nodular liver contours or portal venous collaterals on imaging studies - could be predicted by fibrosis algorithms, calculated using laboratory and demographic features extracted from patients' electronic medical records. To this end, we compared seven EMR-based fibrosis scores with liver imaging studies in a cohort of HCV patients. A search of our health system's patient data warehouse identified 867 patients with chronic HCV infection. A total of 565 patients had undergone at least one liver imaging study and had no confounding medical condition affecting the imaging features or fibrosis scores. Demographic and laboratory data were used to calculate APRI, Fib4, Fibrosis Index, Forns, GUCI, Lok Index and Vira-HepC scores for all viremic patients who had undergone liver imaging. Data points selected for the calculation of these scores were based on laboratory results obtained within the shortest possible time from the imaging study. Areas under the receiver operating curves (AUROC), optimum cut-offs, sensitivities, specificities and positive and negative predictive values were calculated for each score. Seven algorithms were performed similarly in predicting cirrhosis. Sensitivities ranged from 0.65 to 1.00, specificities from 0.67 to 0.90, positive predictive values from 0.33 to 0.38, and negative predictive values from 0.93 to 1.00. No individual test was superior, as the confidence intervals of all AUROCs overlapped. EMR-based scoring systems performed relatively well in ruling out advanced, radiologically-defined cirrhosis. However, their moderate sensitivity and positive predictive values limit their reliability for EMR-based diagnosis.

Overall, of 212 students tested by the ELISA, 12 (5.7% and 31 (14.6% were positive and borderline, respectively. Amongst the 113 veterinary students 11 (9.7% and 19 (16.8% were seropositive and borderline respectively compared with nonveterinary students with corresponding values of 1 (1.0% and 12 (12.1%. The frequency of serological evidence of leptospirosis by the ELISA was statistically significantly (; higher in veterinary students, 26.5% (30 of 113 than in nonveterinary students, 13.1% (13 of 99. By the MAT, the seropositivity for leptospirosis was similar for veterinary students, 7.1% (8 of 113 and nonveterinary students, 7.1% (7 of 99. For veterinary students, the prevalent infecting serovar was Icterohaemorrhagiae Copenhageni while amongst nonveterinary students, the prevalent serovar was Australis Rachmati. Being a veterinary student was the only risk factor that was significantly associated with Leptospira infection indicating that veterinary students need to be cognizant and to practise preventive measures for leptospirosis.

    Veterinary schools and colleges generally include communication skills training in their professional curriculum, but few programs address challenges resulting from language gaps between pet owners and practitioners. Due to shifting US demographics, small animal veterinary practices must accommodate an increasing number of limited English proficient (LEP) Spanish-speaking pet owners (SSPOs). A national survey was conducted to assess the interest and preparedness of US veterinary students to communicate with LEP SSPOs when they graduate. This online survey, with more than 2,000 first-, second-, and third-year US veterinary students, revealed that over 50% of students had worked at a practice or shelter that had LEP Spanish-speaking clients. Yet fewer than 20% of these students described themselves as prepared to give medical information to an LEP SSPO. Over three-fourths of respondents agreed that communication with LEP SSPOs was important for veterinarians in general, and two-thirds agreed that communication with LEP SSPOs was important for themselves personally. Ninety percent of students who described themselves as conversant in Spanish agreed that they would be able to communicate socially with SSPOs, while only 55% said they would be able to communicate medically with such clients. Overall, two-thirds of students expressed interest in taking Spanish for Veterinary Professionals elective course while in school, with the strongest interest expressed by those with advanced proficiency in spoken Spanish. Bridging language gaps has the potential to improve communication with LEP SSPOs in the veterinary clinical setting and to improve patient care, client satisfaction, and the economic health of the veterinary profession.

    Advancement in electrophoresis and mass spectrometry techniques along with the recent progresses in genomics, culminating in bovine and pig genome sequencing, widened the potential application of proteomics in the field of veterinary medicine. The aim of the present review is to provide an in-depth perspective about the application of proteomics to animal disease pathogenesis, as well as its utilization in veterinary diagnostics. After an overview on the various proteomic techniques that are currently applied to veterinary sciences, the article focuses on proteomic approaches to animal disease pathogenesis. Included as well are recent achievements in immunoproteomics (ie, the identifications through proteomic techniques of antigen involved in immune response) and histoproteomics (ie, the application of proteomics in tissue processed for immunohistochemistry). Finally, the article focuses on clinical proteomics (ie, the application of proteomics to the identification of new biomarkers of animal diseases).

    Recent advancements in DNA sequencing methodologies and sequence data analysis have revolutionised research in many areas of biology and medicine, including veterinary infection biology. New technology is poised to bridge the gap between the research and diagnostic laboratory. This paper defines the potential diagnostic value and purposes of next-generation sequencing (NGS) applications in veterinary infection biology and explores their compatibility with the existing validation principles and methods of the World Organisation for Animal Health. Critical parameters for validation and quality control (quality metrics) are suggested, with reference to established validation and quality assurance guidelines for NGS-based methods of diagnosing human heritable diseases. Although most currently described NGS applications in veterinary infection biology are not primary diagnostic tests that directly result in control measures, this critical reflection on the advantages and remaining challenges of NGS technology should stimulate discussion on its diagnostic value and on the potential to validate NGS methods and monitor their diagnostic performance.

    Flip-chip interconnect electronic package boards have been assembled, underfilled, non-destructively evaluated and subsequently subjected to extreme temperature thermal cycling to assess the reliability of this advanced packaging interconnect technology for future deep space, long-term, extreme temperature missions. In this very preliminary study, the employed temperature range covers military specifications (-55 C to 100 C), extreme cold Martian (-120 C to 115 C) and asteroid Nereus (-180 C to 25 C) environments. The resistance of daisy-chained, flip-chip interconnects were measured at room temperature and at various intervals as a function of extreme temperature thermal cycling. Electrical resistance measurements are reported and the tests to date have not shown significant change in resistance as a function of extreme temperature thermal cycling. However, the change in interconnect resistance becomes more noticeable with increasing number of thermal cycles. Further research work has been carried out to understand the reliability of flip-chip interconnect packages under extreme temperature applications (-190 C to 85 C) via continuously monitoring the daisy chain resistance. Adaptation of suitable diagnostic techniques to identify the failure mechanisms is in progress. This presentation will describe the experimental test results of flip-chip testing under extreme temperatures.

    Veterinary clinical trials generate data that advance the transfer of knowledge from clinical research to clinical practice in human and veterinary settings. The translational success of non-regulated and regulated veterinary clinical studies is dependent upon the reliability and reproducibility of the data generated. Clinician-scientists that conduct veterinary clinical studies would benefit from a commitment to research quality assurance and best practices throughout all non-regulated and regulated research environments. Good Clinical Practice (GCP) guidance documents from the FDA provides principles and procedures designed to safeguard data integrity, reliability and reproducibility. While these documents maybe excessive for clinical studies not intended for regulatory oversight it is important to remember that research builds on research. Thus, the quality and accuracy of all data and inference generated throughout the research enterprise remains vulnerable to the impact of potentially unreliable data generated by the lowest performing contributors. The purpose of this first of a series of statement papers is to outline and reference specific quality control and quality assurance procedures that should, at least in part, be incorporated into all veterinary clinical studies.

    Full Text Available The overall objective of this project is research-based development, implementation and evaluation of a game-based learning concept to be used in the veterinary education. Herd visits and animal contact are essential for the development of veterinary competences and skills during education. Yet veterinary students have little occasion to reach/attain a proper level of confidence in their own skills/abilities, as they have limited “training-facilities” (Kneebone & Baillie, 2008. One possible solution mightbe to provide a safe, virtual environment (game-based where students could practise interdisciplinary clinical skills in an easily-accessible, interactive setting. A playable demo using Classical Swine Fever in a pig herd as an example has been produced for this purpose. In order totailor the game concept to the specific veterinary learning environment and to ensure compliance with both learning objectives and the actual learning processes/procedures of the veterinary students, the project contains both a developmental aspect (game development and an exploration of the academic (scholastic and profession (practice oriented learning context. The initial phase of the project was a preliminary exploration of the actual learning context, providing an important starting point for the upcoming phase in which I will concentrate on research-based development, implementation and evaluation of a game-based virtual environment in this course context.

    2006-01-01

    Food-supply veterinary medicine has been an essential part of veterinary degree programs in Australia since the first veterinary school opened in the late nineteenth century. Australian veterinary schools, like others internationally, are being challenged by the relevance of material in current curricula for modern food-supply veterinary medicine. Additionally, student aspirations are a major issue, as curriculum designers balance companion-animal training with the herd/flock-based issues that focus on productivity and profitability. One of the challenges is to examine the relative balance of education in generic skills (self-knowledge, change management, teamwork, leadership, negotiation) with more technically or scientifically based education. An ongoing process of curriculum review and renewal, which involves input from both external and internal stakeholders and allows regular review and assessment, is needed to ensure continuing curriculum relevance.

    There is scant evidence describing antimicrobial (AM) usage in companion animal primary care veterinary practices in the UK. The use of AMs in dogs and cats was quantified using data extracted from 374 veterinary practices participating in VetCompass. The frequency and quantity of systemic antibiotic usage was described.Overall, 25 per cent of 963,463 dogs and 21 per cent of 594,812 cats seen at veterinary practices received at least one AM over a two-year period (2012-2014) and 42 per cent of these animals were given repeated AMs. The main agents used were aminopenicillin types and cephalosporins. Of the AM events, 60 per cent in dogs and 81 per cent in cats were AMs classified as critically important (CIAs) to human health by the World Health Organisation. CIAs of highest importance (fluoroquinolones, macrolides, third-generation cephalosporins) accounted for just over 6 per cent and 34 per cent of AMs in dogs and cats, respectively. The total quantity of AMs used within the study population was estimated to be 1473 kg for dogs and 58 kg for cats.This study has identified a high frequency of AM usage in companion animal practice and for certain agents classified as of critical importance in human medicine. The study highlights the usefulness of veterinary practice electronic health records for studying AM usage. British Veterinary Association.

    Access to the most up-to-date evidence is an important cornerstone for veterinarians attempting to practice in an evidence-based manner; therefore, an understanding of what and how information is accessed is vital. The aim of this study was to identify what resources the UK veterinary profession access and regard as most useful. Based on questionnaires received from veterinarians, the Veterinary Times was nominated as most often read journal or magazine by respondents (n=3572, 79 per cent). In Practice (n=3224, 82 per cent) and the Veterinary Record (n=165, 34 per cent) were seen as most useful by clinicians, and non-clinicians, respectively. Google was the most often nominated electronic resource by all respondents (n=3076, 71 per cent), with Google (n=459, 23 per cent) and PubMed (n=60, 17 per cent) seen as most useful by clinicians and non-clinicians, respectively. The abstract and conclusion sections were the most read parts of scientific manuscripts nominated by all respondents. When looking for assistance with difficult cases, colleagues were the common information choice for clinicians. Different sections of the veterinary profession access information, and deem resources useful, in different ways. Access to good quality evidence is important for the practice of evidence-based veterinary medicine, and therefore, researchers should think about disseminating their findings in a targeted way for optimal use by the profession.

    To describe pet owner preferences within the veterinary community when choosing operative techniques for canine spay. Prospective survey. 1234 respondents from 5 veterinary university teaching hospitals in North America. An electronic survey was distributed to faculty, students, and staff that currently are or previously were dog owners. Responses were analyzed to determine what spay technique respondents would choose for their own dogs. Surgical options offered included open celiotomy, 2-port (TP) laparoscopy, single-port (SP) laparoscopy, and natural orifice transluminal endoscopic surgery (NOTES). TP laparoscopic ovariectomy (OVE) was the most popular choice, followed by SP laparoscopic OVE; NOTES was the least popular technique when all surgical options were available. If only minimally invasive surgeries were offered, 0.3% of respondents would refuse surgery. Nearly half (48%) of respondents were willing to spend between $100 and $200 more for a minimally invasive OVE than for an open celiotomy. Minimally invasive OVE is an acceptable operative approach to those in the veterinary community. Additional study is required to correlate these findings with the general veterinary client population. © 2018 The American College of Veterinary Surgeons.

    2011-04-01

    The beginning of the 21st Century has been characterised by changed political and economic realities affecting the prevention, control and eradication of animal diseases and zoonoses and presenting new challenges to the veterinary profession. Veterinary Services (VS) need to have the capacity and capabilities to face these challenges and be able to detect, prevent, control and eradicate disease threats. Animal health and VS, being a public good, require global initiatives and collective international action to be able to implement global animal disease eradication. The application of the 'One World, One Health' strategy at the animal-human interface will strengthen veterinary capacity to meet this challenge. Good governance of VS at the national, regional and global level is at the heart of such a strategy. In this paper, the author lists the key elements comprising good veterinary governance and discusses the World Organisation for Animal Health (OIE) standards for the quality of VS. The OIE Tool for the Evaluation of the Performance of Veterinary Services (OIE PVS Tool) is introduced and its relevance in assessing compliance with OIE standards to prevent the spread of pathogens through trade is highlighted. A firm political commitment at the national, regional and international level, with provision of the necessary funding at all levels, is an absolute necessity in establishing good governance of VS to meet the ever-increasing threats posed by animal and human pathogens.

    This research investigates vet and vet nurse career identity through the qualitative methodology of narrative enquiry. It derives learning and understanding from these empirical data to assist the veterinary profession to adjust to the changing industry landscape. Through a case series of 20 vets and vet nurses' career stories, this paper seeks understanding about career identity and its impact on individuals and organisations in the light of industry consolidation. Findings suggest that career is central to identity for many veterinary professionals who tend to have a strong sense of self; this is particularly evident around self as learner and technically competent, teacher and educator, ethical and moral and dedicated and resilient. Consequently, mismatches between 'who I am' and 'what I do' tend not to lead to identity customisation (to fit self into role or organisation) but to the search for alternative, more identity-compatible employment. This study offers a valuable insight for employers, veterinary professionals and universities. It suggests that businesses can gain competitive advantage and employees achieve validation and enrichment by working towards organisational and individual identity congruence and that teaching veterinary professionals with contemporary business in mind may develop graduates with a more sustainable identity.

    This special issue of Veterinary Immunology and Immunopathology summarizes the Proceedings of the 9th International Veterinary Immunology Symposium (9th IVIS) held August 2010, in Tokyo, Japan. Over 340 delegates from 30 countries discussed research progress analyzing the immune systems of numerous food animals and wildlife, probing basic immunity and the influence of stress, genetics, nutrition, endocrinology and reproduction. Major presentations addressed defense against pathogens and alternative control and prevention strategies including vaccines, adjuvants and novel biotherapeutics. A special Organisation for Economic Co-operation and Development (OECD) Co-operative Research Programme Sponsored Conference on "Vaccination and Diagnosis for Food Safety in Agriculture" highlighted the particular issue of "Immunology in Bovine Paratuberculosis". In April 2010 there was an outbreak of foot-and-mouth disease (FMD) in the southern part of Japan. This stimulated a special 9th IVIS session on FMD, sponsored by the World Organization for Animal Health (OIE) and the Ministry of Agriculture, Forestry and Fisheries (MAFF) of Japan, to discuss improvements of FMD vaccines, their use in FMD control, and risk assessment for decision management. The 9th IVIS was supported by the Veterinary Immunology Committee (VIC) of the International Union of Immunological Societies (IUIS) and included workshops for its MHC and Toolkit Committees. Finally VIC IUIS presented its 2010 Distinguished Service Award to Dr. Kazuya Yamanouchi for "outstanding contributions to the veterinary immunology community" and its 2010 Distinguished Veterinary Immunologist Award to Dr. Douglas F. Antczak for "outstanding research on equine immunology". Published by Elsevier B.V.

    2007-01-01

    This article presents a historical perspective on veterinary anatomic pathology in the United Kingdom from the late nineteenth century to the present. Prior to World War II, the specialty was a rather general one that also included bacteriology and parasitology and was only slightly affected by strong Germanic developments in cell and tissue pathology. The few notable figures of this era include John McFadyean, Sidney Gaiger, and J.R.M Innes. The specialty developed strongly in the second half of the twentieth century, led by a small number of individuals, and was greatly aided by the development of specialist colleges and residency training. Key individuals of this era include W.F. Blakemore, Ernest Cotchin, R.J.M. Franklin, W.F.H. Jarrett, A.R. Jennings, and A.C. Palmer. A remarkable feature of this period has been the increased employment of veterinary pathologists in biomedical industry and in private diagnostic laboratories. While standards of pathology practice have benefited from the college initiatives, there are major financial constraints on the availability of funded training posts in the United Kingdom, and there remain considerable shortages in the supply of pathologists trained to contemporary standards. The acknowledged professional and scientific importance of veterinary pathology needs to be translated into effective financial support for the training that underpins competence in this specialty. Further developments seem likely to be dominated by advances in the technology of tissue handling, applications of molecular biology to pathology, and greater use of telepathology in teaching, in quality assurance, and in continuing professional development.

    To investigate the current status of forensic veterinary pathology, a survey was composed directed at pathology laboratories and institutes, mostly in Europe. The questions included number of and type of cases, resources available, level of special training of the investigating pathologists and the general view on the current status and future of the discipline. The surveys were sent to 134 laboratories and were returned by 72 respondents of which 93 per cent work on forensic pathology cases. The results indicate scarcity of training opportunities and special education, and insufficient veterinary-specific reference data and information on forensic analyses. More cooperation with human forensic pathology was desired by many respondents, as was more interaction across country borders. British Veterinary Association.

    The topics discussed at the NATO ARW included the new nanodevice applications, novel materials, mesoscopic superconductivity and biosensors. There have been many significant advances in the past two years and some entirely new directions of research are just opening up. Recent advances in nanoscience have demonstrated that fundamentally new physical phenomena are found when systems are reduced in size with dimensions, comparable to the fundamental microscopic length scales of the investigated material. Recent developments in nanotechnology and measurement techniques now allow experimental investigation of transport properties of nanodevices. Great interest in this research connected with development of spintronics, molecular electronics and quantum information processing.

    The purpose of this study was to determine the nature and degree of coverage of human relations and the human-animal bond in veterinary curricula across North America. The attitudes and opinions of a cohort of veterinary students and alumni about human relations skills and human-animal bond training in the veterinary program was also investigated. Twenty veterinary schools across North America were contacted and data were collected regarding their coverage of human relations and the human-animal bond in the curriculum. A survey was developed to measure attitudes and opinions about this type of training. The survey was disseminated to students in years 1 to 4 and alumni from the Ontario Veterinary College (OVC). Data were analyzed descriptively. Based on availability of contact people, 20 schools in North America were contacted, and all participated in the study. Each of the veterinary schools surveyed has incorporated strategies for teaching human relations skills through required courses, electives, guest speakers, and/or community service programs. The overall participation rate for OVC students was 53%. Ninety-nine percent of all students surveyed agreed that their ability to deal with people using effective human relations skills was a concern, and all students said they would like to receive more training in this area. There was a 41% participation rate for OVC alumni. Fifty-five percent of alumni said they had learned enough in the veterinary program to employ effective human relations skills in practice, yet 65% felt they had not received enough instruction in addressing the human-animal bond specifically. It is apparent that veterinary schools recognize the need to prepare entry-level practitioners to deal with the human-animal bond and with human relations. It is also evident that students and practitioners value receiving information of this nature in the curriculum and desire further training. Specific learning objectives for veterinary curricula have

    Laparoscopic surgery minimizes tissue trauma and speeds recovery, but its uptake into veterinary clinical practice has been slow. Laparoscopy is distinctly different from traditional open surgery and a reduced working area and loss of depth perception are among the challenges that the surgeon must get to grips with. Indeed, it is often lack of the necessary skills, rather than the cost of equipment, that presents the greatest obstacle. This article is aimed at practitioners keen to embrace minimally invasive surgery and advises on how to develop excellence in laparoscopic skills. It makes the case for simulation training and outlines methods that can be instituted in practice at low cost and with comparatively little time expenditure. It also describes technological advances that have already increased the success of veterinary 'keyhole' surgery, as well as those that look promising for the future. Simulation training has been an intense area of research and publication within the past 15 years. This article draws on that evidence base and the experience gained by the author and her research team, which is at the forefront of efforts to develop laparoscopic training for veterinarians.

The focus was on veterinary acupuncture (AP and immunology, and the event was sponsored by the International Veterinary Acupuncture Society (IVAS. IVAS is a non-profit organization dedicated to promoting excellence in the practice of veterinary AP as an integral part of the total veterinary health care delivery system. The Society endeavors to establish uniformly high standards of veterinary AP through its educational programs and accreditation examination. IVAS seeks to integrate veterinary AP and the practice of Western veterinary science, while also noting that the science of veterinary AP does not overlook allied health systems, such as homeopathy, herbology, nutrition, chiropractic, kinesiology, etc. (www.ivas.org.

    This study addressed how students' undergraduate science courses influence their academic performance in a veterinary program, and examined what implications this may have for the veterinary admissions process. The undergraduate transcripts and veterinary school rankings of current third-year veterinary students at Colorado State University were coded and analyzed. Because the study found no statistically meaningful relationships between the pre-veterinary coursework parameters and class rank, it could be concluded that veterinary schools may be unnecessarily restricting access to the profession by requiring long and complicated lists of prerequisite courses that have a questionable predictive value on performance in veterinary school. If a goal of veterinary schools is to use the admissions process to enhance recruitment and provide the flexibility necessary to admit applicants who have the potential to fill the current and emerging needs of the profession, schools may want to re-evaluate how they view pre-veterinary course requirements. One of the recommendations generated from the results of this study is to create a list of veterinary prerequisite courses common to all schools accredited by the Association of American Veterinary Medical Colleges. It is suggested that this might simplify pre-veterinary advising, enhance recruitment, and provide flexibility for admitting nontraditional but desirable applicants, without impacting the quality of admitted veterinary students.
