Plan estratégico de la generación fluvial de electricidad en el Perú

El sector energético es uno de los sectores clave para el desarrollo nacional, siendo indispensable garantizar el abastecimiento de energía para hacerlo posible. El Perú cuenta con un importante potencial de generación fluvial de electricidad por aprovechar, sin embargo es importante no dejar de lado el desarrollo de las otras fuentes alternativas. El Ministerio de Energía y Minas, tiene como misión promover el desarrollo sostenible y competitivo de las actividades energéticas y mineras asegurando el suministro de energía de forma eficaz y eficiente. Adicionalmente se encarga de velar por el cumplimiento del marco legal vigente (Ley de Concesiones Eléctricas), de conducir las políticas energéticas orientadas al aprovechamiento óptimo de los recursos sin perjudicar el medio ambiente, y de promover la inversión privada en dicho sector para la modernización de la infraestructura. La Ley de Concesiones Eléctricas aprobada mediante Decreto Ley 25844 en diciembre del año 1992, dividió la industria en tres segmentos (generación, transmisión y distribución), permitiendo el ingreso de empresas privadas al sistema. La presente tesis plantea un planeamiento estratégico para la Generación Fluvial de Electricidad en el Perú, que permitirá aprovechar el potencial de los ríos con lo cual se logrará que la generación fluvial de electricidad se incremente al 2022 y se mantenga como la tercera fuente de generación de electricidad en el Sector Eléctrico Interconectado Nacional del Perú.The energy sector is one of the key sectors for national development, being essential to ensure the supply of energy to make it happen. Perú has a significant potential to harness hydropower generation, however it is important aside disallow the development of alternative sources. The Ministry of Energy and Mines, is to promote sustainable and competitive energy and mining activities ensuring energy supply effectively and efficiently. Additionally responsible for ensuring compliance with the existing legal framework (Electricity Concessions Law), driver-oriented energy policies optimal use of resources without harming the environment, and to promote private investment in the sector to modernize infrastructure. Electricity Concessions Law Decree Law 25844 approved in December of 1992, the industry divided into three segments (generation, transmission and distribution), allowing the entry of private companies into the system. This thesis presents a strategic plan for the River Generating Electricity in Perú, which will harness the power of rivers which will ensure that electricity generation to increase river to 2022 and remains as the third generation source electricity in the National Interconnected Electric Sector of Perú.Tesi

Vaccines for the Leishmaniases: Proposals for a Research Agenda

The International Symposium on Leishmaniasis Vaccines, held in Olinda, Brazil, on March 9–11, 2009, congregated international experts who conduct research on vaccines against the leishmaniases. The questions that were raised during that meeting and the ensuing discussions are compiled in this report and may assist in guiding a research agenda. A group to further discussion on issues raised in this policy platform has been set up at http://groups.google.com/group/leishvaccines-l

High incidence of Noonan syndrome features including short stature and pulmonic stenosis in patients carrying NF1 missense mutations affecting p.Arg1809: genotype-phenotype correlation

Neurofibromatosis type 1 (NF1) is one of the most frequent genetic disorders, affecting 1:3,000 worldwide. Identification of genotype-phenotype correlations is challenging because of the wide range clinical variability, the progressive nature of the disorder, and extreme diversity of the mutational spectrum. We report 136 individuals with a distinct phenotype carrying one of five different NF1 missense mutations affecting p.Arg1809. Patients presented with multiple cafe-au-lait macules (CALM) with or without freckling and Lisch nodules, but no externally visible plexiform neurofibromas or clear cutaneous neurofibromas were found. About 25% of the individuals had Noonan-like features. Pulmonic stenosis and short stature were significantly more prevalent compared with classic cohorts (P<0.0001). Developmental delays and/or learning disabilities were reported in over 50% of patients. Melanocytes cultured from a CALM in a segmental NF1-patient showed two different somatic NF1 mutations, p.Arg1809Cys and a multi-exon deletion, providing genetic evidence that p.Arg1809Cys is a loss-of-function mutation in the melanocytes and causes a pigmentary phenotype. Constitutional missense mutations at p.Arg1809 affect 1.23% of unrelated NF1 probands in the UAB cohort, therefore this specific NF1 genotype-phenotype correlation will affect counseling and management of a significant number of patients

Contribution of a common ability in average and variability judgments

This study intends to test whether or not participants’ ability to extract two different kinds of ensemble information (i.e., average and variance) are correlated

Note assistant: A multimodal application for taking, making, and reviewing notes

Note-taking and note-making are important academic skills even in the digital age as these allow students to be more active learners. Note Assistant is a multimodal tablet application that provides digital tools to facilitate the process of taking, making and reviewing digital notes. Similar to existing note-taking application, Note Assistant uses different input modalities, including touch, pen and voice. It also provides additional features such as note annotation, sharing and integration, multi-media mapping, note templates, and visual revision history. The application has been tested on various devices including Acer Iconica Tab, Samsung Galaxy Tab & plus, and Motorola Xoom. Results from tests with secondary and tertiary students as participants over a two-week period showed the potential of the application as a technology to support individual and collaborative learning
