A Simple Cardiovascular Model for the Study of Hemorrhagic Shock
2020
Hemorrhagic shock is the number one cause of death on the battlefield and in civilian trauma as well. Mathematical modeling has been applied in this context for decades; however, the formulation of a satisfactory model that is both practical and effective has yet to be achieved. This paper introduces an upgraded version of the 2007 Zenker model for hemorrhagic shock termed the ZenCur model that allows for a better description of the time course of relevant observations. Our study provides a simple but realistic mathematical description of cardiovascular dynamics that may be useful in the assessment and prognosis of hemorrhagic shock. This model is capable of replicating the changes in mean …
Miguel del Prado, pintor de retablos en Valencia. Su fallecimiento en las Germanías (1521)
2017
Miguel del Prado, a painter who formed a company with Miguel Esteve in order to paint the now-lost Valencia town hall chapel in 1519, is an artist for whom there is scant documentary evidence. He has been identified with the anonymous Master of the Grifo, but this has been questioned recently. The author here offers news of a contract given to del Prado for an altarpiece in the Rosary Chapel of the old convent of Santo Domingo in Valencia that he was unable to fulfill due to his untimely death. It has been possible to certify that he perished on the battlefield of Almenara during the Germanias Revolt of 1521. Therefore the chronology for this painter has now been reduced by more than 16 yea…
Computer Games and Fine Motor Skills
2012
The study seeks to determine the influence of computer games on fine motor skills in young adults, an area of incomplete understanding and verification. We hypothesized that computer gaming could have a positive influence on basic motor skills, such as precision, aiming, speed, dexterity, or tremor. We examined 30 habitual game users (F/M – 3/27; age range 20–25 years) of the highly interactive game Counter Strike, in which players impersonate soldiers on a battlefield, and 30 age- and gender-matched subjects who declared never to play games. Selected tests from the Vienna Test System were used to assess fine motor skills and tremor. The results demonstrate that the game users scored apprec…
The Combitube, Self-Inflating Bulb, and Colorimetric Carbon Dioxide Detector to Advance Airway Management in the First Echelon of the Battlefield
2006
Combat lifesavers and Army medics are regular combat soldiers who possess skills that enable them to provide lifesaving assistance to combat casualties. Although their training is not equal to that of paramedics, combat lifesavers and Army medics are trained to assess casualties for airway obstruction, as well as the presence or absence of spontaneous ventilation. They are also familiar with the same basic airway maneuvers that are required for blind insertion of the esophageal-tracheal double-lumen airway (ETDLA). Use of the ETDLA in combination with an esophageal detector device and a colorimetric carbon dioxide detector would require skill similar to that which they already possess in pe…
Comparison between two different cardiovascular models during a hemorrhagic shock scenario
2020
Hemorrhagic shock is a form of hypovolemic shock determined by rapid and large loss of intravascular blood volume and represents the first cause of death in the world, whether on the battlefield or in civilian traumatology. For this, the ability to prevent hemorrhagic shock remains one of the greatest challenges in the medical and engineering fields. The use of mathematical models of the cardiocirculatory system has improved the capacity, on one hand, to predict the risk of hemorrhagic shock and, on the other, to determine efficient treatment strategies. In this paper, a comparison between two mathematical models that simulate several hemorrhagic scenarios is presented. The models considere…
Territory and memory: The Landing of the Allies in Sicily in 1943
2012
The concept of memory (memorial site) has gained crucial importance in recent years for the identification of places (areas) and in the affirmation of local identities. The memorial sites are areas where usually tragic events have occurred and resulted in a cultural change. In these places there are still signs of these historical events and/or tangible and intangible indications created by the society such as: monuments, obelisks, marble inscriptions, others. Sicily represents an ideal area for studying memorial sites; not only because of the number of dominations in the past centuries, but also for the significance of all places where the mafia has taken its root. These elements have caus…
