    The National School of Veterinary Medicine, which is included among our old educational centers, was established in 1853, and at that time was annexed to the National School of Agriculture. It was not until 1916, or 63 years later, that it became independent, and began to develop a great cultural and spiritual program, to grow, and to change its courses to produce the best type of professional men to meet the increasing needs of the people

    This paper presents the richness of submillimeter spectral features in the high-mass star forming region AFGL 2591. As part of the CHESS (Chemical Herschel Survey of Star Forming Regions) Key Programme, AFGL 2591 was observed by the Herschel/HIFI instrument. The spectral survey covered a frequency range from 480 up to 1240 GHz as well as single lines from 1267 to 1901 GHz (i.e. CO, HCl, NH3, OH and [CII]). Rotational and population diagram methods were used to calculate column densities, excitation temperatures and the emission extents of the observed molecules associated with AFGL 2591. The analysis was supplemented with several lines from ground-based JCMT spectra. From the HIFI spectral survey analysis a total of 32 species were identified (including isotopologues). In spite of the fact that lines are mostly quite week, 268 emission and 16 absorption lines were found (excluding blends). Molecular column densities range from 6e11 to 1e19 cm-2 and excitation temperatures range from 19 to 175 K. One can distinguish cold (e.g. HCN, H2S, NH3 with temperatures below 70 K) and warm species (e.g. CH3OH, SO2) in the protostellar envelope.Comment: Accepted to A&

    A Case of Multisystem Inflammatory Syndrome in Children Mimicking Acute Appendicitis in a COVID-19 Pandemic Area.

    The outbreak of the novel coronavirus (2019-nCoV) began in Wuhan, China and spread rapidly throughout the world. As of now, there have been numerous reports demonstrating clinical, radiological and pathological findings in adults. In children, the disease has essentially been seen as mild and self-limiting. However, more recently, children have been presenting with findings reminiscent of Kawasaki\u27s disease. And secondary to this, the benign nature of COVID-19 disease in children is beginning to be challenged. This phenomenon is now referred to as multisystem inflammatory syndrome in children (MIS-C). Further understanding the clinical course in MIS-C and its temporal association with coronavirus disease 2019 will be paramount for treatment and public health decision making. This correspondence describes a case of MIS-C with gastrointestinal manifestations mimicking acute appendicitis in a child presenting from a COVID-19 endemic area

    Job Burnout: An Examination of Outpatient Clinics

    The purpose of this study was to examine job burnout of medical providers in outpatient clinics. Job burnout is a psychological syndrome resulting from job interpersonal stressors; it is measured using three dimensions: (1) emotional exhaustion – feelings of being emotionally overextended and exhausted by one’s work, (2) depersonalization -a unfeeling and impersonal response toward patients, and (3) personal accomplishment – feelings of competence and achievement in one’s work (Maslach & Jackson, 2020). Using a convenience sample, healthcare providers in Southern Nevada were asked to participate. The study was approved by the University of Nevada, Las Vegas, Internal Review Board (IRB). After an initial Maslach Burnout Inventory Human Services Survey for Medical Personnel (MBI-HSS (MP)) was administered virtually (due to COVID-19), healthcare providers were presented with a job burnout educational in-service regarding how to identify and define job burnout, a summary of research and findings regarding employee stress, information of when to seek help, and a discussion of how job burnout affects patient care. After a 60-day period, the MBI-HSS (MP) was re-administered, voluntarily, to the same employees. This project’s aim was to improve job burnout subscale scores in a 60-day period using a job burnout educational intervention

    A new scaling property of turbulent flows

    Full text link
    We discuss a possible theoretical interpretation of the self scaling property of turbulent flows (Extended Self Similarity). Our interpretation predicts that, even in cases when ESS is not observed, a generalized self scaling, must be observed. This prediction is checked on a number of laboratory experiments and direct numerical simulations.Comment: Plain Latex, 1 figure available upon request to [email protected]

    Potential role of predators on carbon dynamics of marine ecosystems as assessed by a Bayesian belief network.

    Get PDF
    While the effects of climate change on top predators are well documented, the role of predation on ecosystem level carbon production is poorly developed, despite it being a logical consequence of trophic dynamics. Trophic cascade effects have shown predator mediated changes in primary production, but we predict that predators should lower the overall biomass capacity of any system with top down control. Through a simple Bayesian belief network model of a typical marine foodweb, we show that predator removal, as is common through activities such as fishing and shark finning, results in higher biomasses of lower trophic level fish and zooplankton, resulting in higher net carbon production by the system. In situations common throughout much of the ocean, where activities such as shark finning and over fishing reduce the highest tropic levels, the probability of net carbon production increasing in the model was ~ 60%, and unlike previous studies on simple food chains, trophic cascade effects were not present. While the results are preliminary, and sources of uncertainty in data and models are acknowledged, such results provide even more strength to the argument to protect open sea fish stocks, and particularly large predators such as sharks, cetaceans and game fish

    Developing a results-oriented training program for middle managers in the Belize public service.

    All developing countries struggle to build administrative structures and institutions that have the capacity to facilitate national development. Countries in the Caribbean have learned from each other\u27s experiences. These countries, including Belize, share a similar colonial history, similar social and economic development patterns and have adopted the same type of government and public administration. It was for this reason that this research examined the framework of management training in four Caribbean islands: Jamaica, Bahamas, Barbados and Trinidad and Tobago. As a concept, training is seen as an intervention strategy to facilitate the induction, acceptance and implementation of government policies. Specifically, training is a planned, continuous effort to improve employee competency levels and ultimately to increase organizational productivity. The targeted areas of efficiency include upgrading of knowledge, skills and attitudes of public officials, especially those at the middle management levels. Research and experience in developing countries have shown that the acquisition of certain competencies provides new stimulus to the performance of managers. If training efforts are to be successful, they must employ a well-planned systematic approach of altering the attitudes and behaviour of managers. The Government of Belize has recognized the performance deficiency of officers at the middle management level. Top level administrators are in the process of identifying new ways of improving the training system to address this problem. The model proposed for middle management training in this thesis identifies competencies required of middle managers and suggests programs which will provide the targeted skills. Process evaluation is recommended to determine the value of the training programs. A new thrust in the proposed system is the involvement and commitment of supervising managers to the entire training process.

    Impact of Inclement Weather on Overwinter Mortality of Montezuma Quail in Southeast Arizona

    Get PDF
    Inclement weather such as droughts or hard freezes are known to negatively impact quail species and population viability models exist which have evaluated northern bobwhite (Colinus virginianus) response to summer and winter catastrophes. Previous research suggests inclement weather may be an important factor that contributes to mortality of Montezuma quail (Cyrtonyx montezumae), but few data have been collected to evaluate actual rates of overwinter mortality. We evaluated the overwinter mortality of Montezuma quail in southeast Arizona following an episode of severe winter weather consisting of 27.54 cm of precipitation, which occurred from January to March 2010. Overwinter mortality for radio-marked birds (n 1⁄4 23) was 95.6%. Total abundance using flush counts at a control site estimated an 88% reduction in the population following the episode of above-average precipitation. Post-hunting season flush counts across multiple study sites throughout the Coronado National Forest also support this trend. The 3-year (2007–2009) average (6 SD) (41.67 6 4.73) of birds flushed was ~ 80% higher than number of birds (n 1⁄4 8) flushed in the 2010 post-hunting season
