Natural Science (NS) , 2015, DOI: 10.4236/ns.2015.77039
Abstract: It is of great knowledge nowadays that the use of fossil fuels is responsible for the emission of gases that intensify the greenhouse effect, which threatens the survival of the humankind. The gravity of this fact could be mitigated through the indirect use of solar energy for fuels derived from vegetable that can be planted and cultivated by the world of renewable and non-polisher. Microalgae play an important role in this regard, as they have promising characteristics as potential raw material for the production of biofuels, able to absorb large amounts of CO2. Chlorophyll organisms convert these simple substances in the atmosphere, absorbing sunlight into chemical energy stored, that is, compounds with high energy, biomass can also be used to obtain biocompounds human nutritional supplement and food animal, however, have been found an important number of difficulties to economically viable production like high cost of production of dry biomass and oil extraction. Here, we review the main approaches of biorefinery concept appearing as an alternative to achieve economic viability of the production of bio-diesel based on microalgae. The major points are the following: 1) use of re-residual water, 2) marketing of Carbon Credits, and 3) development of co-products resulting from high value added.

Abstract: La calidad de vida depende directamente del medio natural y su calidad. La valoración sobre la salud no solo depende de las necesidades y los conocimientos del individuo, sino también de las condiciones de vida y trabajo. Se realiza un estudio donde se muestran los cambios sociales del modo y estilo de vida de la población y su relación con el proceso salud-enfermedad, así como los cambios del modo y estilo de vida que ayudan a promover salud y prevenir enfermedades, basados precisamente en la existencia de los factores determinantes del estado de salud y la modificación que sufren estos por el constante desarrollo social y científico-técnico. Se constata que el modo y estilo de vida de la población depende del sistema socioeconómico imperante. Los cambios del modo y estilo de vida determinan cambios en las condiciones y la calidad de vida de las personas y modifican el proceso salud-enfermedad.

Abstract: Se realizó un estudio descriptivo tranversal del Consultorio 103-1 del Policlínico "Moncada" desde enero de 1999 a agosto del 2001 con el objetivo de evaluar el estado de salud bucal de la población. El conocimiento del estado de salud bucal de la población resulta indispensable para la correcta planificación, organización y control de la atención estomatológica. Se seleccionó una muestra de 441 personas estratificadas por grupos de edades a las que se les realizó el examen clínico; para la recolección de los datos se utilizó una adaptación de la encuesta básica de la OMS. En la población estudiada las maloclusiones que predominan son las ligeras y la enfermedad parodontal es más frecuente en el grupo de 35-59 a os. En relación con las necesidades de tratamiento, se observó que hay un comportamiento similar en la atención primaria y secundaria desde el punto de vista ortodóncico y periodontal. En las necesidades de tratamiento protésico, el grupo más necesitado es de 35-59 a os y el tipo de prótesis, la parcial removible.

América Latina Hoy , 2010,
Abstract: RESUMEN: El objetivo de este artículo es analizar la introducción de criterios de transparencia y rendición de cuentas en la gestión de las regalías petroleras en Colombia. A través del estudio de los Comités de Seguimiento y Evaluación a la Inversión de Regalías (CSIR), se intenta indagar si los dispositivos de control ciudadano implican nuevas condiciones de gobernanza en el sector petrolero. Para ello, se presentan primero los argumentos que facilitan la inscripción de la gestión local de las regalías como un tema problemático en la agenda pública. Posteriormente, se describe el surgimiento de los CSIR en respuesta a dicho problema, se analizan los factores que permiten su desarrollo y el nuevo tipo de interacciones Estado-Sociedad que genera su implementación en el ámbito local. En el último aparte, se presentan las inquietudes que suscitan estas nuevas condiciones de gobernanza en términos de su contenido democrático y de sus alcances. Palabras clave: gobernanza, gestión de regalías petroleras, accountability social, democracia local, Colombia. ABSTRACT: This article aims at analyzing the introduction of transparency and accountability standards for oil royalties’ management in Colombia. Through the study of the Royalties’ Investment Evaluation and Follow-Up Committees (CSIR), the article intends to understand if the social accountability mechanisms create new governance conditions in the oil sector. The first part presents the arguments that support the positioning of royalties’ management as a problematic topic on the public agenda. Then, the emergency of CSIR is described as a response to such problem, analyzing the elements that make possible its development and the new type of State- Society interactions engendered through its implementation at the local level. Finally, the article presents some questions about the democratic content and the real scope of these new governance conditions. Key words: governance, oil royalties’ management, social accountability, local democracy, Colombia.

Abstract: the first potassium salts ores found in colombia are presented and described; they are located in the santander province, in la mesa de los santos area, between los santos village and the rio chicamocha canyon. from a geological point of view, the mineralization is associated to the sediments of the paja formation, early cretaceous in age, and is located near the base of the formation. in the study area the main structure is the villanueva syncline which involves, from bottom to top, los santos, rosablanca, paja, tablazo and simiti formations. the mineralization consists of small veins where the main mineral is singenite (k2ca[so4]2 - h2o) with small amounts of carbonates and accidental minerals. in the host rock, minerals like langbeinite (k2mg2[so4]3) and rinneite (k3na[fe,cl]6) are present; they show that the rock was formed in an evaporitic environment and that detailed studies of that sequence may lead to the discovery of other mineralizations of economic interest.

Abstract: The knowledge of man in the Spain of the Enlightment was conditioned by prejudices and intolerance, was subjected to the verdict of science and religion. The anatomical studies had an outstanding role being converted in a new scientific front; however, to the appointment didn't miss erudites and propagandists like Feijoo or Hervás and Panduro, who dedicated their thinkings to the analysis of the human being. The anthropological frame would remain defined whether considered the publication and diffusion that the work of Buffon had, in spite of the inquisitorial censorship. El conocimiento del hombre en la Espa a del siglo de las Luces estuvo condicionado por prejuicios e intolerancia, fue sometido al dictamen de la ciencia y de la religión. Los estudios anatómicos tuvieron un destacado papel convirtiéndose en un novedoso frente científico; sin embargo, a la cita no faltaron eruditos y divulgadores como Feijoo o Hervás y Panduro, quienes dedicaron sus reflexiones al análisis del ser humano. El marco antropológico quedaría definido si consideramos la publicación y difusión que la obra de Buffon tuvo a pesar de la censura inquisitorial.
Osteoid Osteoma Mimicking Triangular Fibrocartilage Complex Injury: Diagnosis and Review of Treatment
J. M. Lamo-Espinosa,A. González,S. Amillo
Case Reports in Surgery , 2012, DOI: 10.1155/2012/612106
Abstract: We report the case of osteoid osteoma (OO) with ulnar styloid involvement. A review of the literature has been made with the aim of defining the special behaviour of OO when it is near the articular surface. That behaviour can affect the diagnosis, masking the real etiology of the pain, delaying the diagnosis, missing the diagnosis, or what is more serious, conducting an inadequate treatment. We propose a treatment algorithm conducted based on the localization near or far from articular surface and the superficial or deep localization.
