Iniciativa de decreto sobre la propuesta de reforma política del presidente Felipe Calderón
Adrián Joaquín Miranda Camarena,Luis Antonio Corona Nakamura
Espiral , 2010,
Abstract: El presidente Felipe Calderón presenta un paquete de iniciativas, entre las que se encuentra la reforma política que tiene como fin dar más poder al ciudadano y fortalecer la democracia. Además, alienta al ciudadano para que participe y perciba que sus órganos de representación estén más atentos a sus demandas y necesidades. La iniciativa apunta a transformar los rasgos estructurales del régimen político autoritario en el ámbito del ejercicio del poder, no limitándose a lo electoral, por lo que además se pretende salir del estancamiento político y cambiar la dinámica viciosa de la representación legislativa y el conflicto frecuente entre Ejecutivo y Congreso. Por lo que consideró era urgente plantear una serie de cambios, a fin de que nuestro sistema político provenga del sufragio efectivo y pase a una democracia efectiva.

Abstract: mangrove oyster, crassosterea rhizophorae, is one of the mollusks with greatest perspectives for aquaculture development in the caribbean and the tropical atlantic coast. even though, many studies have been carried out to establish its culture, there has not been established which and how environmental factors influence its growth under culture condition. spats with a mean size of 30 mm were suspended in ?spanish baskets? at a depth of 4 m during 6 months. the experiment was carried on at la restinga lagoon, margarita island, venezuela. each month oysters were measured (ventral-dorsal and antero-posterior), and weighted (dry weight from conch,tissue and fouling). survivorship was also evaluated. water temperature was recorded continuously and weekly measurements of secchi depth, salinity, oxygen, total, organic and inorganic seston, and chlorophyll a were determined. results show 89% increase in ventral-dorsal size reaching sizes of 54.5 mm. dry weight of tissue at the end of the study period was 0.48 g after a decrease during the warmer months of august and september, indicating temperature as an important factor controlling spawning. the high and constant phytoplanktonic biomass present in la restinga lagoon showed that food availability was not a limiting factor, which together with the small variability in the studied environmental variables, made impossible to identify factors controlling growth and survival of crassostrea rhizophorae in long-line suspended culture. the exception was the occasional predation by cymatium snails.

Abstract: Background and objective: endoscopic polypectomy may allow curative resection of invasive adenocarcinoma on colorectal adenoma. Our goal is was to determine the factors associated with complete endoscopic resection of invasive adenocarcinoma. Methods: retrospective observational study. We included 151 patients with invasive adenocarcinoma on adenomas endoscopically resected between 1999 and 2009. We determined those variables independently related to incomplete resection by a logistic regression. Relation was expressed as Odds Ratio (OR) and its 95% confidence interval (95% CI). Results: patients were predominantly male (66.2%) and their mean age was 68.03 ± 10.65 years. Colonoscopy was incomplete in 84% of the patients and 60.3% had synchronous adenomas. Invasive adenocarcinoma was mainly located in distal colon (90.7%) and morphology was pedunculated in 75.5%. The endoscopic average size was 22.61 ± 10.86 mm. Submucosal injection was required in 32.5%. Finally, the resection was in one piece in 73.5% and incomplete in 8.6% of the adenocarcinomas. Factors independently associated with incomplete endoscopic resection were size (mm) (OR 1.08, 95% CI 1.03-1.14, p = 0.002), sessile or flat morphology (OR 8.78, 95% CI 2.24-34.38, p = 0.002) and incomplete colonoscopy (OR 4.73, 95% CI 1.15-19.34, p = 0.03). Conclusions: endoscopic polypectomy allows complete resection of 91.4% of invasive adenocarcinomas on colorrectal adenoma in our series. Factors associated with incomplete resection were the size of the lesion, sessile or flat morphology and incomplete colonoscopy. Antecedentes y objetivo: la polipectomía endoscópica puede permitir la resección con intención curativa del adenocarcinoma invasivo sobre adenoma de colon. Nuestro objetivo es determinar los factores asociados a la resección endoscópica completa del adenocarcinoma invasivo. Métodos: estudio retrospectivo observacional. Se incluyeron 151 individuos con un adenocarcinoma invasivo sobre adenoma resecado endoscópicamente entre 1999 y 2009.

Revista Venezolana de Oncología , 2006,
Abstract: La presentación clínica de los tumores carcinoides varía, dependiendo de sus características físicas, lugar de origen y de si son o no productores de sustancias hormonalmente activas. Los tumores carcinoides pueden clasificarse desde un punto de vista anatomopatológico o bien embriológico, siendo esta la más frecuente. Se presenta el caso de un paciente masculino de 49 a os de edad, a quién en control médico se evidenció tumor en epigastrio. En la valoración paraclínica con TAC de abdomen, se demostró un tumor heterogéneo en relación con lóbulo hepático izquierdo con realce del contraste endovenoso. Se le realizó una laparotomía exploradora, evidenciándose tumor de aproximadamente 14 cm de diámetro de localización retroperitoneal; la anatomía patológica reporta tumor neuroendocrino y a las tinciones de inmunohistoquímica reportaron tumor carcinoide. Debido a la poca frecuencia de la localización retroperitoneal de esta patología, se presenta el caso clínico y se revisa la literatura. The clinical presentation of the carcinoid tumors may vary, depending on its physical characteristics, place of origin and if they are or not producing of hormonally active substances. The carcinoid tumors can be classified from two points of view: anatomopathological or embryological, being the latter, the most frequent. We present a clinical case of 40 years old male patient, whom in medical exam was evident an epigastric tumor. In the para clinic evaluation with abdominal scan, was demonstrated a heterogeneous tumor in relationship with hepatic left lobe, with enhancement of endovenous constrast. An exploratory laparatomy was performed, finding a tumor of approximating 14 cm of diameter, at retro-peritoneal localization; the anatomy pathological study reported: neuroendocrine tumor and the immunehys tochemical stain reported a carcinoid tumor. Due to the slight frequency of the retroperitoneal location of this pathology, we report this clinical case and the literature is reviewed.
Estrategias competitivas para los productores cafetaleros de la región de Córdoba, Veracruz, frente al mercado mundial

Contaduría y administración , 2008,
Abstract: Este trabajo tiene como objetivo identifi car las estrategias competitivas para los productores cafetaleros de la región de Córdoba, Veracruz. Esto les permitirá competir en un mercado mundial globalizado, el cual se caracteriza por la sobreproducción de café en países como Brasil, Vietnam y Colombia, la fuerte competencia en el mercado de materias primas, el control del grano por un número limitado de países torrefactores y el descenso sostenido de los precios del café oro en el mercado mundial. Estas condiciones complicaron la atención de los cultivos para algunos productores y el abandono total de sus plantaciones para otros, como resultado del descenso de los precios internacionales. El descuido de la producción nacional y la pérdida de espacios han sido aprovechados por los países que vieron la crisis como una oportunidad para extender sus mercados sobre sus competidores más débiles.

Noel Bonfilio Pineda Jaimes, Joaquín Bosque Sendra, Montserrat Gómez Delgado, Roberto Franco Plata, Xanat Antonio Némiga, Luis Ricardo Manzano Solís
Journal of Geographic Information System (JGIS) , 2012, DOI: 10.4236/jgis.2012.43025
Abstract: This work aims to develop simulation models that allow locating adequate areas for forest plantations in the state of Mexico. It combines multi-criteria evaluation (MCE) techniques and geographic information systems (GIS) to analyze and simulate future scenarios for forest plantations under three major objectives: commercial production, restoration and protection, and agroforestry. Results demonstrate the potential of this method to integrate different variables of social, economic and environmental nature, and for solve some problems of forest activities and management by locating the most suitable areas for this forestal activity.
