Mechatronic Developement of New Products Oriented to the Available Technological Capability Desarrollo mecatrónico de nuevos productos orientado a la capacidad tecnológica disponible
Genovevo Morejón Vizcaíno,José Ricardo Díaz Caballero,José Arzola Ruiz
Revista Cubana de Ingeniería , 2011, DOI: 10.1234/rci.v2i3.60
Abstract: This paper proposes a technological innovation methodology denominated "Mechatronic development of new products oriented to the available technological capacity". It is shown as a study case of the development of hydromotors with radial pistons. Este trabajo propone una metodología de innovación tecnológica denominada "Desarrollo mecatrónico de nuevos productos orientado a la capacidad tecnológica disponible". Se muestra como caso de estudio el desarrollo de un hidromotor de pistones radiales.
Modelado y experimentación computacional de la etapa de compresión en motores de pistones libres
Morejón-Vizcaino,Genovevo;
Ingenier?-a Mec??nica , 2012,
Abstract: the goal of the investigation is the development of a free piston engine with an auxiliary hydraulic bomb that substitutes the function of the hydraulic accumulator with the objective of to improve the density of power and to diminish the demands in the dynamic behavior of the components. the used method is the "development of new products mecatrónicos". in the investigation to arrive to the new knowledge an analytic prototype is developed to carry out pc-experiments. the mathematical model is deduced for the stage of the compression, the algorithm and the analytic prototype was obtained. the results of the experiments show different restrictions in the geometry and the materials to use as well as the tendencies in the behavior of the different hydraulic parameters.
Coma hiperosmolar
Soler Morejón,Caridad;
Revista Cubana de Medicina , 1999,
Abstract: it is known that hyperosmolar coma or nonketotic hyperglycemic states (nkhs) is a severe complication of diabetes mellitus and that it si still nowadays a challenge for the emergency care personnel due to its difficult management and to the serious consequences resulting from a late or wrong diagnosis. that's why it is one of the most severe urgencies of the diabetic patients. the most important aspects of its diagnosis, treatment and complications were dealth with in this review. special emphasis was made on the 3 fundamental milestones of the treatment, namely, the administration of liquid, administration of insulin and potassium intake. we consider that this paper may serve as a guide to approach this serious affection.
Acidosis láctica
Soler Morejón,Caridad;
Revista Cubana de Medicina , 2000,
Abstract: it is know that lactic acid is a last product of glucose anaerobic metabolism, that, in normal conditions, serum levels reach 2 meq/l or less. most of lactate is released in a very efficacious way by liver and is used in gluconeogenesis or to obtain energy. if there are significant increases of serum lactate figures with a decrease of metabolism of the conversion of lactate in pyruvate, a situation of metabolic acidosis frequently serious will present, which may provoke death of patient. from the clinical point of view, it must be suspected in a patient with non well explained metabolic acidosis and a high anion gap, which is over 25-30 meq/l, even in presence of renal failure, ketoacidosis or ingestion of a toxic agent. that prevention of tissue hypoxia play a very significant role and to this effect, all measures contributing to guarantee a good tissue perfusion. importance of a appropiate control of diabetes mellitus, a rigurous selection of hypoglycemic agents, contribution of thiamine in risk patients, amongst other measures are emphasized
Presión intraabdominal y sepsis
Soler Morejón,Caridad;
Revista Cubana de Medicina , 2001,
Abstract: a literature review was made on the increase of intraabdominal pressure that causes a series of well-known adverse effects on the cardiovascular, respiratory and renal function. it was confirmed that effects on splachnic circulation have been less studied; however, the authors agree with other authors as to the importance of keeping adequate levels of intraabdominal pressure to avoid intestinal ischemia and thus the damage to the function of the intestinal barrier due to the effects that this may have on the development of bacterial and toxin translocation and on sepsis in general
Estadística Piloto: paquete estadístico digital educacional para las investigaciones epidemiológicas
Piloto Morejón,Manuel;
Revista de Ciencias M??dicas de Pinar del R?-o , 2010,
Abstract: the practical use of biostatistics is a concern for any researcher. objective: four tools were created aimed at providing the mathematical calculation of the statistical tests used in epidemiological researches as well as its application and interpretation, these tools use a free software, without property openoffice.org.calc 2.3 of the unix ubuntu 8.04 of linux operative system (with a copy in microsoft office excel to its generalization) having the title of: "piloto's statistics. a digital-educational statistical package for the epidemiological researches" in pinar del rio during 2008 material and method: the software contains 18 statistical tests; chi square test (includes yates's correction), fisher's test of exact probability, odds ratio, relative risk, attributable risk percent and kappa's and youden's rates, dependent tests a-b-c-d of contingency table 2x2. besides; the calculation of the mean, standard deviation, variance, z statistic and mc nemar's chi square test. results: the tools were validated by means of professional programs and generalized in the final researches of the medical specialties, master's degree and other researches of the province. the tools were presented in provincial, national events and in south africa (2007) and they are fundamental topics in postgraduate courses of applied biostatistics to the tutor, without the substitution of the professional syllabuses; the tools are added to easier the acquisition of knowledge in biostatistics. the most important advantages of these tools are: the simplicity, applicability and immediacy, as well as the results in unison, easy interpretation, help in spanish language and little size.
Software proyecto y presupuesto de una investigación en salud
Piloto Morejón,Manuel;
Revista de Ciencias M??dicas de Pinar del R?-o , 2011,
Abstract: introduction: to prepare a project for scientific research is a difficult task due to the diversity of basic knowledge about methodology of scientific research, biostatistics and economy which are necessary to face up the different sections of the project. objective: to guarantee the suitable groundwork of research projects at any level as well as the uniform preparation for economic calculation (estimate) of the whole research projects of the province. materials and methods: a software package providing researchers with the preparation of research projects was designed taking as basis the official guide for a branch project of citma (according to the ministerial resolution 110/2009) and the numerous mathematical calculations of the estimate for a research project of automated way from the primary economic data. results: the software package does not need to be installed. it is a useful tool to every researcher due to it easy management. it concentrates the fundamental and simplicity in a user's manual. it is applicable and of small size (kb), reliable and efficient, having ease of use and maintenance having at the same time social, technological, scientific and economic benefits. this software is used by the 100% of the researchers in the province for the branch, territorial and institutional projects, useful for those writing thesis in the termination of medical specialty and master's degree as well.

Revista Cubana de Medicina , 1999,
Abstract: Se conoce que el coma hiperosmolar o estado hiperglucémico no cetótico (EHNC), es una grave complicación de la diabetes mellitus que constituye aún en nuestros días un reto para el emergencista, por lo difícil de su manejo y las consecuencias tan graves que se derivan del diagnóstico tardío o errado, por lo que constituye una de las urgencias más graves del diabético. En esta revisión se presentaron los aspectos más importantes de su diagnóstico, tratamiento y complicaciones. Se hizo especial énfasis en los 3 pilares fundamentales del tratamiento, a saber, la administración de líquido, la administración de insulina y el aporte de potasio. Nos proponemos que este trabajo pueda servir de guía para el abordaje de esta grave afección. It is known that hyperosmolar coma or nonketotic hyperglycemic states (NKHS) is a severe complication of diabetes mellitus and that it si still nowadays a challenge for the emergency care personnel due to its difficult management and to the serious consequences resulting from a late or wrong diagnosis.
