Energy Efficiency and Renewable Energy in Latin America: Policies towards Sustainable Development

Gilberto De Martino Jannuzzi 한국외국어대학교 국제지역연구센터 2017 국제지역연구 Vol.21 No.2

Latin America possesses great natural resources and many opportunities are emerging for new investments and innovation, since many countries are planning to modify the structure of their energy networks in order to give a greater role to renewables. High electricity prices in most of the region, growing demand, problems of energy security have been the main drivers for the recent expansion of the renewable energy market. Socio-economic issues are priority targets in LA countries, social inequality and poverty are still major challenges in the region. On the other hand, technological developments have permitted innovative approaches, including private participation, the creation of social enterprises and business models to provide for electricity services to low income populations and small business. In spite of the recent progress regarding the widespread dissemination of the ‘new renewable’ and energy efficient technologies, the reduction of CO2 emissions, in major LA countries have not been significant along the past decade. We suggest in this paper an area which deserves attention so that these technologies can play a relevant role towards the sustainable development of the region.

Crustose calcareous algae (CCA) constitute one of the main reef builders on the Abrolhos Bank, Brazil. Once CCA taxonomy is locally understood, differences in growth-forms may be useful for the delimitation of taxa using characteristics such as the presence or absence of surface protuberances. Here, growth-forms were used to identify and quantify the most common CCA taxa on the shallow reefs (3-10 m) of the Abrolhos Bank to determine possible changes in the CCA community over a period of 10 years, and the ecological significance of CCA to local reefs was interpreted. The CCA assemblages were surveyed from 2006-2015 by using fixed photoquadrats at four sites in the inner (10-20 km from the mainland) and mid-shelf reefs (40-75 km from the mainland). The five most common CCA taxa were Pneophyllum conicum, the Lithophyllum kaiserii / Lithophyllum sp. complex, Melyvonnea erubescens, the Hydrolithon boergesenii / Porolithon onkodes complex and Peyssonelia sp. The overall mean CCA cover on the reefs was 20%. A comparison with a previous monitoring study in the same region indicated that the CCA cover nearly doubled from 2003-2008 to 2006-2015. This study reveals that the coral-killing species P. conicum dominated CCA flora on the shallow Abrolhos reefs in the last decade, and the local specific abundance of CCA slightly fluctuated over time and was species- and site-specific. The information obtained in this study contributes to the understanding of the ecology of the key calcifying components of the Abrolhos reefs and provides a useful baseline for exploring the responses of CCA to future environmental changes.

Precise mapping of protein-binding sites on DNA is an important application of atomic force microscope (AFM) imaging. For a reliable measurement of distances on curved DNA molecules, an image-processing algorithm is required, which extracts the DNA contour from topographic AFM data. To this end we implemented an image analysis method providing an efficient way to obtain the contour together with a physical map of single and multiple protein-binding sites. This method relies on a calculation of the height profile along the DNA fragment, allowing one to determine the DNA length and the relative position of the binding site occupied by a protein. As a first test, complexes of the LexA repressor protein from the Escherichia coli SOS system and DNA fragments containing a specific LexA binding site (recA operator) were imaged by the torsional resonance mode (TR mode) and analyzed using the specialized algorithm. A topographic height of less than 0.5 nm of the DNA molecules indicates repulsive imaging conditions.

University Cooperation in Structural Violence, Public Administration, Climatic Changes, and Environmental Education

( Gilberto Javier Cabrera Trimiño ) 부경대학교 글로벌지역학연구소 2021 Journal of Global and Area Studies(JGA) Vol.5 No.1

This investigation focuses on the importance of University Cooperation. In order to analyse and achieve such cooperation in all strategies and policy projections for sustainable development we have applied an holistic conception of the environment, structural violence, and the importance of environmental education to face the impact of climatic change. This research is being done in coordination with the International Network, Iberoamerican University Network of Space and Mobility, and the Administration, Sports and Education Network. Evaluations of the administration of university knowledge are being done to contribute to the environmental security with a holistic perspective of public administration. This research contributes to the emergence and development of systemic processes of collaboration that have as their premise the interrelation between population, environment and development from an integrative optics and inter and multi-disciplinary approach to the relationship of structural violence--university --society--climatic changes and sustainable development. The results offer alternatives for integrative reflections to highlight the importance of the Caribbean University Cooperation and Pacific Universities for the initiatives, to enhance preparedness before the impacts of the climatic change and natural disasters in all levels of organization of public administration and society. The investigation strengthens the importance of cooperation to implement political environmental education that contributes to generate sustainable synergies in the efficient and effective construction of integrative methodologies and of participation by administration in environmental university knowledge.

Modeling Chagas Disease at Population Level to Explain Venezuela’s Real Data

Gilberto Gonza´lez-Parra,Benito M. Chen-Charpentier,Moises Bermu´dez 질병관리본부 2015 Osong Public Health and Research Persptectives Vol.6 No.5

Objectives: In this paper we present an age-structured epidemiological model for Chagas disease. This model includes the interactions between human and vector populations that transmit Chagas disease. Methods: The human population is divided into age groups since the proportion of infected individuals in this population changes with age as shown by real prevalence data. Moreover, the age-structured model allows more accurate information regarding the prevalence, which can help to design more specific control programs. We apply this proposed model to data from the country of Venezuela for two periods, 1961-1971, and 1961-1991 taking into account real demographic data for these periods. Results: Numerical computer simulations are presented to show the suitability of the age-structured model to explain the real data regarding prevalence of Chagas disease in each of the age groups. In addition, a numerical simulation varying the death rate of the vector is done to illustrate prevention and control strategies against Chagas disease. Conclusion: The proposed model can be used to determine the effect of control strategies in different age groups.

This work investigates a hybrid polyester composite consisted of Curauá natural fibres and organophilic clay nanoparticles. A Taguchi method is used to identify the effects of fibre fraction (10, 20 and 30 wt%), alkaline treatmentconcentration (NaOH, 2.5, 5 and 10 wt%), treatment time (2, 4 and 8 h) and nanoparticle content (2.5, 5 and 10 wt%) on the mechanical behaviour of the hybrid composites under tension and three-point bending. X-ray, FTIR and microstructural analysis are performed to assess the treated and untreated fibre surfaces. The optimum combination of the process parameters for the tensile and flexural properties is: fibre content at 30 wt%, NaOH concentration at 5 wt%, treatment time at 8 h and nanoclay inclusions at 5 wt%. A mean tensile and flexural strength of 36.13 MPa and 32.55 MPa are obtained, whichrepresents percent increases of 39.22 % and 25.43 % compared to the polyester polymer in pristine condition.

Supratentorial Intraparenchymal Haemorrhages during Spine Surgery

Leung, Gilberto Ka Kit,Chan, Johnny Ping Hon The Korean Neurosurgical Society 2014 Journal of Korean neurosurgical society Vol.55 No.2

Intracranial haemorrhages are rare but potentially life-threatening complications of spine surgery. Most reported cases involved subdural or cerebellar haemorrhages; supratentorial parenchymal bleeding is very uncommon. We report a 28-year-old woman who underwent resection of a thoracic Ewing's sarcoma, and developed fatal haemorrhages around her cerebral metastases during surgery. The clinical presentations, possible pathogenesis and potential preventive measures are discussed. Patients with disseminated metastases within the neural axis are at risks of intracranial complications during spine surgery. The presence of intracranial mass lesions should be considered as a relative contraindication to intradural spine surgery.

Indicio Y Presuncion : Problemas Doctrinarios

Barrantes, E. Gilberto Cabanillas 단국대학교 1988 論文集 Vol.22 No.-

La fuerza probatoria del INDICIO se halla en la naturaleza intima de la prueba misma que determina una necesaria relacian de causalidad. Si el raciocinio inductivo es la forma de trabajar con el indicio, bar que recoger, consecuentemente, todos los indicios posibles en cada caso particular y someterlos al analisis logico para encontrar una premisa mayor que tenga per contenido un juicio especifico de causalidad. Una premisa que afirme la existencia de un sujeto particular incluido en el sujeto especffico de la mayor. Y una conclusion que atribuya al subjeto particular el predicado atributdo al sujeto especifico. Es en esta conclusion donde se encuentra, propiamente, la probanza del hecho criminal. El juicio do CAUSALIDAD, expresado en la premisa mayor del raciocinio inductive, solo demuestra la relacion entre una especie do causas y una especie de efectos, es este su caracter especifico. Todo juicio de causalidad, es siempre general en relacion al caso particular en que se quiere formular, a lo que debe concurrir la experiencia, fruto de la observacion de varios casos particulares. Ademas, hay que considerar la fuerza relacional de lo conocide con lo desconocido, para establecr el valor probatorio del indicio. En la prueba penal, el hecho CONOCIDO-el indicio/-es distinto del DESCONOCIDO. El efecto es lo que se conoce, la causa es la que se desconoce. El hecho externo, que hace de ndicador, cuando se presenta come potencia causal, no puede probar ser efecto sino de una manera mas o menos Probable, pero no contingents, porque on la esfera de las cosas contingentes no hay causa : (on el sentido de potencias causales), que deben producir-necesaria-monte- un efecto dado.
