Abstract: background: dental caries is a transmissible, infectious, chronic and multifactorial disease; prevails in the infancy and constitutes the fundamental cause of the dental loss. objective: to determine the loss of the first permanent molar tooth in children from 7 to 13 years. method: an observational, descriptive, longitudinal and prospective study was conducted in 63 children from 7 to 13 years belonging to the sector 1 of the urbanization ?las margaritas?, carirubana municipality, falcón state, from september 2005 to may 2006. the studied variables were: age, sex, damage caused to the oral structures and oral hygiene of the boy. results: of the total of patients, 16 correspond to the male sex, what represented the 57.4% of the sample and 12 patients to the female one for a 42.6%. relating to the age a greater number of patients between 10-11 years with a total of six children was obtained (21,4%). the tooth with greater index of absence was the first right lower molar with a total of 16 for the 37.2%. of the most common oral affections caused by the loss of the first permanent molar tooth, was found that 17 children presented extrusion of the antagonist and 13 unilateral mastication. on analyzing the hygiene in the studied children was observed that just in 11 patients (39,2%) was acceptable and in the 60.8% (17 of the patients) were evaluated as no acceptable. conclusions: the male sex was the most affected one by the loss of the first permanent molar tooth and mostly oral hygiene was no acceptable.

Abstract: introduction: haemodialysis (hd) lines are traditionally primed with sodium heparin and saline solution, which entails the haemorrhagic risk associated to the passing of heparin into the blood. aim: to compare hd dialyser priming with and without sodium heparin, in terms of coagulation, dialytic efficacy, and economic efficacy. material and method: a randomized, prospective studio of 3482 sessions with 109 hd patients (x 66.8±15 years, 40% women, 44% diabetic, 45% with high-flow tunnelled catheter, 50% native iaf, 5% prosthetic iaf). 1827 sessions carried out with fifty-nine patients were included in the control group (primed with saline solution + sodium heparin) and 1455 sessions with patients in the study group (primed with saline solution). the monitoring period was 5 months. variables related to the coagulation of the circuit and the efficacy of the dialysis were analysed: selected blood flow (qb) and effective qb, final status of the dialyser, number of changes of dialyser, number of changes of the arterial line, number of changes of the venous, average kt/hour measured by ionic dialysance and heparinization of the circuit. the efficacy in economic terms was also studied. results: there are no significant differences in the results related to coagulation and efficacy of the dialysis obtained in both groups, except x of heparin with low molecular weight (2476±1089 iu in the study group compared to 2854±1414 iu in the control group). priming without heparin represents a saving of 0.50 € per session. conclusions: priming with saline solution does not affect the hd dose, and does not entail a greater risk of coagulation of the system compared to a priming solution to which heparin has been added, avoids the risk of heparin passing into the bloodstream, reduces handling in the connection protocols and reduces costs.

Abstract: abstract this paper presents the results of the probabilistic safety assessment to the radiotherapy treatment with an electron linear accelerator for medical use, which was conducted in the framework of the iberian-american forum of radiological and nuclear regulatory agencies. potential accidental exposures during the treatment of patients, workers and members of the public were assessed, although the study was mainly focused on patients. the methodology of failure modes and effects analysis was used to define accident initiating events and methods of event tree and fault tree analysis to determine the accident sequences that may occur. after quantifying the frequency of occurrence of the accident sequences, an important analysis was carried out in order to determine the most significant events from the point of view of safety. the major contributors to risk were identified as well as the most appropriate safety recommendations to reduce it.
RAíCES HISTóRICAS DEL PROYECTO EDUCATIVO MARTIANO
Felipe de Jesús Pérez Cruz
Revista Historia de la Educación Latinoamericana , 2011,
Abstract: Me interesa el estudio del pensamiento pedagógico cubano, caribe o y latinoamericano. Desde el punto de vista teórico metodológico, privilegio el estudio del tejido socio cultural y de las mentalidades, desde el eje de las ideologías y las ideas políticas en particular. Parto de considerar que los movimientos de ideas, proyectos y acciones pedagógicas que desde la última década del siglo XVIII se desarrollaron en Cuba, resultan vitales para el abordaje de la Historia de la Educación en el país, y que precisamente José Martí Pérez hereda y desarrolla esa tradición pedagógica, con la propuesta de un proyecto educativo cultural revolucionario, que impactó la teoría y la práctica pedagógica de su época, y trasciende hasta nuestros días. Asumo el criterio relativo a la existencia en José Martí de una pedagogía y didáctica orgánicas. Probar la historicidad y unidad sistémica de este presupuesto resulta la tarea principal que me he trazado.
From Community Control to Consent Decree: Puerto Ricans Organizing for Education and Language Rights in 1960s and '70s New York City
Anthony De Jesús,Madeline Pérez
Centro Journal , 2009,
Abstract: Using literature review, archival analysis, and interviews this article describes major events, organizations, and individuals who advanced the educational rights of Puerto Ricans in New York City during the 1960s and 1970s. The post-WWII migration of Puerto Ricans introduced a new political battleground to the city's schools-that of language rights, which were linked to the continuing struggle over the governance of public schooling in a multiracial, multicultural, and multilingual city and nation. The organizing and political activity of Puerto Ricans during this period resulted in unprecedented policies, structures, and institutions designed to fully incorporate them into the economic and political life of the city.

Abstract: Se realizó un estudio descriptivo transversal para caracterizar la diabetes mellitus en 52 pacientes pertenecientes a 5 consultorios del Médico de Familia. El universo lo constituyeron 2 189 habitantes de dichos consultorios localizados en el Policlínico Comunitario Docente "Tula Aguilera" del municipio Camagüey, en el período comprendido del 1ro de enero hasta el 31 de diciembre de 2000. Se compilaron los datos a través de una encuesta confeccionada al efecto por los autores de la investigación, lo cual se convirtió en el registro primario, y fueron procesados en computadora. Los principales resultados demostraron que la prevalencia alcanzó el 2,36 %, predominó el grupo de edades 60-80 a os con un 63,46 % del total de la muestra, así como la diabetes mellitus no insulinodependiente (90,38 %). Concluimos que el sexo predominante fue el femenino, el antecedente de madre diabética prevaleció, y el factor de riesgo más común fue la obesidad.

New Approach for Lead, Zinc and Copper Ions Elimination in Cyanidation Process to Improve the Quality of the Precipitate  [PDF]
José R. Parga, Jesús V. Valdés, Jesús L. Valenzuela, Gregorio Gonzalez, L. María de J. Pérez, T. Francisco Cepeda
Materials Sciences and Applications (MSA) , 2015, DOI: 10.4236/msa.2015.62015
Abstract: The Merrill-Crowe zinc-precipitation process has been applied worldwide on a large number of operations for recovering gold and silver from cyanide solutions. However, in some of the large plants this precipitate is of low quality, because copper and especially lead are precipitated along with gold and silver resulting in a higher consumption of zinc powder, fluxes in the smelting of the precipitate, formation of mate and short life for crucibles. In this research, a method is proposed to recover lead, zinc and copper cyanide ions from barren solutions, from the Merrill-Crowe process with hydroxyapatite before the filter press. This technology is based on inducing nucleated precipitation of zinc, copper and silver ions in a serpentine reactor, using sodium sulfide as the precipitator and sulfuric acid for pH control. This procedure was successfully applied at WILLIAM Mining and BACIS Mining Group in México.
