La aplicación del principio de transparencia en los procesos de selección en la contratación estatal colombiana a través del Secop

El Principio de Transparencia aplicado a los procesos de selección en la contratación estatal colombiana a través del SECOP es un rito confesional, es decir, debe estar presente tanto y desde la licitación pública como y hasta en la contratación directa, pues ese ‘derecho de acceso de los ciudadanos a la información pública y la transparencia de la actuación política y administrativa que a través de él se asegura son considerados hoy con toda razón (…) elementos esenciales para la formación de una opinión pública libre y garantías imprescindibles para el buen funcionamiento de las instituciones y para el ejercicio de los derechos fundamentales sobre los que descansa todo sistema democrático’

Principios de la contratación estatal aplicables a los reglamentos especiales de contratación de la agencia nacional de hidrocarburos

El estatuto de contratación administrativa (Ley 80 de 1993 y Ley 1150 de 2007) por regla general regula todos los negocios jurídicos que surgen de la actividad de la Administración Pública, pero teniendo en cuenta las actividades que desarrollan algunas entidades del Estado esta regla tiende a presentar excepciones, como es el caso de aquellas Entidades que tienen por objeto la Exploración y Explotación de los Recursos Naturales renovables y no renovables. El principal actor del régimen excepcional de contratación para la exploración y explotación de hidrocarburos es la Agencia Nacional de Hidrocarburos (ANH), el cual cuenta con dos reglamentos de contratación especial para la asignación de áreas y de contratación misional, en donde por disposición legal debe dar aplicación a los principios de contratación contemplados en el estatuto General de la Contratación pública (Transparencia, economía, responsabilidad y el deber de selección objetiva), este trabajo de investigación procura realizar una mirada analítica a cada procedimiento para determinar con posterioridad el grado de acatamiento de la orden legal establecida en el artículo 76 de la Ley 80 de 1993 así como sus principales falencias

OCUPAÇÃO DO BAIRRO BELVEDERE III: HISTÓRICO E ASPECTOS LEGAIS BELO HORIZONTE/MINAS GERAIS/BRASIL

O presente artigo se configura como um estudo de caso e apresenta uma discussão a partir da análise do contexto do rápido crescimento do bairro Belvedere III, localizado na cidade de Belo Horizonte, no estado de Minas Gerias, no Brasil. O bairro que era ocupado por residências unifamiliares se verticalizou a partir da mudança da legislação realizada pelo prefeito Sérgio Ferrara, em 1988 e se tornou alvo de intensa polêmica envolvendo a associação de moradores, a prefeitura e os interesses imobiliários na construção de condomínios verticais destinados a uma camada da população com elevado poder aquisitivo. A análise apresenta discussões sobre a legalidade da verticalização do bairro Belvedere III que vêm sendo apresentadas nas duas últimas décadas, em função da não observação da legislação ambiental vigente, pois o bairro é vizinho à Serra do Curral, uma área de reserva ambiental de grande importância na recarga fluvial do sistema hídrico da região, protegida por diversos instrumentos legais e tombada desde 1960. Instrumentos jurídicos de coerção e de punição só foram acrescidos às leis ambientais na última década, impedindo assim que estas leis retroagissem para sanar os problemas que hoje se apresentam.

EL REASEGURO MARÍTIMO: especial referencia al ordenamiento jurídico español e italiano

El estudio del reaseguro puede abordarse desde múltiples puntos de vista (actuarial, financiero, jurídico...) para hacer frente a las cuestiones y a los problemas de diversa índole derivados del mismo. En el presente trabajo de investigación se examina la configuración jurídica del contrato de reaseguro como técnica de transferencia de riesgos y, en particular, el examen se centra en los riesgos de la navegación marítima. La relevancia del reaseguro marítimo se explica por su utilidad especialmente en el comercio internacional ya que sin este contrato ninguna actividad de transporte ni aseguradora podría llevarse a cabo. La especialidad y la gravedad de los riesgos asociados a la navegación junto con la entidad de los siniestros acaecidos en el mar impide que los cuantiosos gastos sean asumidos por la empresa de la navegación o que las elevadas indemnizaciones sean abonadas exclusivamente por una sola empresa aseguradora. La tesis aborda, con especial atención, aspectos esenciales de la estructura de esta institución mercantil como la relación con el seguro marítimo del que trae causa, los riesgos e intereses, las funciones y los principios, entre otros muchos. A lo largo del texto se ofrece un análisis de Derecho comparado recurriendo a la legislación, la doctrina y la jurisprudencia de España e Italia pero, atendiendo al carácter eminentemente internacional del contrato y con el objetivo de ofrecer un tratamiento sistemáticamente completo de la materia, también se han incluido referencias a otros sistemas jurídicos. El tratamiento del reaseguro, desde una perspectiva jurídica, obliga además a tener en cuenta las cláusulas de los contratos como expresión de la práctica profesional y de la realidad del Derecho del seguro privado.

Aspectos técnicos da monitorização da pressão intracraniana pelo método subaracnóideo no traumatismo craniencefálico grave

Two hundred and six patients with severe head injury (Glasgow Coma Scale of 8 points or less after nonsurgical resuscitation on admission), managed at Intensive Care Unit-Hospital das Clínicas - Universidade Estadual de Campinas were prospectively analysed. All patients were assessed by CT scan and 72 required neurosurgical intervention. All patients were continuously monitored to evaluate intracranial pressure (ICP) levels by a subarachnoid device (11 with subarachnoid metallic bolts and 195 with subarachnoid polyvinyl catheters). The ICP levels were continuously observed in the bedside pressure monitor display and their end-hour values were recorded in a standard chart. The patients were managed according to a standard protocol guided by the ICP levels. There were no intracranial haemorrhagic complications or hematomas due the monitoring method. Sixty six patients were punctured by lateral C1-C2 technique to assess infectious complications and 2 had positive cerebrospinal fluid samples for Acinetobacter sp. The final results measured at hospital discharge showed 75 deaths (36,40%) and 131 (63,60%) survivors. ICP levels had significantly influenced the final results (p<0,001). The subarachnoid method to continuously assess the ICP levels was considered aplicable, safe, simple, low cost and useful to advise the management of the patients. The ICP record methodology was practical and useful. Despite the current technical advances the subarachnoid method was considered viable to assess the ICP levels in severe head injury.

Espectroscopia optogalvânica: alguns aspectos relevantes

In this work we present the optogalvanic effect in ionized gases in an historical perspective. This effect was observed for the first time by Foote and Mohler in 1925, and explained by Penning in 1928 for mixtures (Ne-Ar) and pure gases (or vapours) in 1937. Also, we show some aspects of the contributions of Romenian authors for the development of optogalvanic spectroscopy, which was used as a new technique only after 1964.

A short historical development of discoveries of the nitrogen cycle, the nitrogen sources for agriculture and the ammonia synthesis (in laboratory and industry) are presented. Some brief aspects of nitrogen chemistry are described. Short biographies of Fritz Haber and Carl Bosch, the main persons in this epopee, are also presented.

Cromatografia de afinidade por íons metálicos imobilizados (IMAC) de biomoléculas: aspectos fundamentais e aplicações tecnológicas

Immobilized Metal Ion Affinity Cromatography - IMAC - is a group-specific based adsorption applied to the purification and structure-function studies of proteins and nucleic acids. The adsorption is based on coordination between a metal ion chelated on the surface of a solid matrix and electron donor groups at the surface of the biomolecule. IMAC is a highly selective, low cost, and easily scaled-up technique being used in research and commercial operations. A separation process can be designed for a specific molecule by just selecting an appropriate metal ion, chelating agent, and operational conditions such as pH, ionic strength, and buffer type.

Análise de aspectos socioeconômicos e tecnológicos da agropecuária na Bacia Hidrográfica do Rio Mogi Guaçu

Currently, owing to the occurrence of environmental problems, along with the need of environmental preservation, both the territory management of Hydrographic Basin and the conservation of natural resources have proven to have remarkable importance. Thus, the mean goal of the research is to raise and scrutinize social-economic and technologic data from the Mogi Guaçu River Hydrographic Basin (São Paulo, Brazil). The aim is to group municipalities with similar characteristics regarding the collected data, which may direct joint actions in the Hydrographic Basin Management. There were used both the methods of factorial analysis and automatic hierarchical classifications. Additionally, there is going to be applied a Geographical Information System to represent the outcomes of the methods aforementioned, through the evolvement of a geo-referenced database, which will allow the obtainment of information categorically distributed including theme maps of interest. The main characteristics adopted to group the municipalities were: agricultural area, sugar cane production, small farms, animal production, number of agriculture machinery and equipments and agricultural income. The methodology adopted in the Mogi Guaçu River Hydrographic Basin will be analyzed vis-à-vis its appropriateness on basin management, as well as the possibility of assisting the studies on behalf of the São Paulo Hydrographic Basin groups, to regional development.

Flora e aspectos auto-ecológicos de um encrave de cerrado na chapada do Araripe, Nordeste do Brasil

This study subject to investigate the floristic composition and richness, the reproductive phenological patterns, the dispersal syndromes and life forms of species of a disjunt cerrado in semiarid climate at Araripe plateau during a one year period. We found 107 species and 41 families. Fabaceae, Myrtaceae, Poaceae, Apocynaceae, Euphorbiaceae and Malpighiaceae showed the largest number of species. For 47 of the woody species found, we studied the geographical distribution based on 27 papers of the Brazilian cerrados. Twelve species are of widespread occurence in the cerrado, and 13 are restricted to the Araripe plateau. Zoocory, autocory, and anemocory are the predominant syndromes of dispersal. The predominant life forms were phanerophytes (50.7%), hemicriptophytes (14.9%) and camephytes (13.1%). The cerrado of Araripe have lower species richness than continous cerrados, but a similar pattern of reproductive phenology, dispersal syndromes and life forms in more humid zones.

Aspectos ultra-estruturais dos canais secretores em órgãos vegetativos e reprodutivos de Anacardiaceae

The study assessed phloem canal development and ultra-structure in shoot apices of Spondias dulcis G. Forst., phloematic canal ultra-structure in shoot apices of Tapirira guianensis Aubl., and floral canal ultra-structure and development and fruit canal ultra-structure of the latter specie. The flower and fruit canals of Anacardium humile St.Hil. were also studied ultra-structurally. The canals in shoot apices of S. dulcis show schizo-lysigenous formation and the floral canals of T. guianensis show schizogenous development. Epithelial cells of S. dulcis and T. guianensis canals have rough endoplasmic reticulum, free ribosomes, elongated plastids of several shapes with osmiophilic inclusions and dictyosomes with production of vesicles. Such organelles participate in the secretion of a heterogeneous exudate, which is comprised of hydrophilic and lipophilic substances. The epithelial cells of the fruit of A. humile present elongated plastids with circular membrane system, which are involved in the synthesis of lipophilic substances. The results of the ultra-structural analyses of the epithelial cells corroborate the results previously obtained in a histochemical study. In the histochemical study, lipophilic and hydrophilic substances were identified in the canals of T. guinanensis and S. dulcis and only lipophilic substances were identified in the canals of A. humile. Based on the ultrastructural aspects of the secretory canals of T. guianensis and S. dulcis we concluded that the plastids of the epithelial cells of the two species are different although they produce secretion of similar composition. A new record for the family is the presence of a great number of circular plastids in epithelial cells of the fruit of Anacardium humile. The pattern found in the secretory canals of the studied species is the ecrine type of secretion release.

Formação de professores: aspectos históricos e teóricos do problema no contexto brasileiro

This article deals with the theme of teacher training from the historical and theoretical perspectives. In the first part, the historical focus is introduced and the trajectory of teacher training in Brazil is examined, dividing it into six periods beginning with the passing of the Law of Schools of First Letters in 1827 and closing with the promulgation of the new law for national education in 1996. The second part deals with theoretical aspects, considering the two basic models of teacher training, their implications for the training of teachers of primary and pre-school education, the dilemma resulting from the contraposition between the two models and the way for overcoming it and concluding with observations on the training of teachers for special education.
