    Chile is a long (2650 miles), narrow (250 miles at widest point) country sandwiched between the Andes mountains and the Pacific. The northern desert is rich in copper and nitrates; the temperate middle region is agricultural and supports the major cities, including Santiago, the capital, and the port of Valparaiso; and the southern region is a cold and damp area of forests, grasslands, lakes, and fjords. The country is divided into 12 administrative regions. Chile's population of 12.5 million are mainly of Spanish or Indian descent or mestizos. Literacy is 92.3%, and the national language is Spanish. Infant mortality is 18.1/1000, and life expectancy is 68.2 years. 82% of the people are urban, and most are Roman Catholics. Chile was settled by the Spanish in 1541 and attached to the Viceroyalty of Peru. Independence was won in 1818 under the leadership of Bernardo O'Higgins. In the 1880s Chile extended its sovereignty over the Strait of Magellan in the south and areas of southern Peru and Bolivia in the north. An officially parliamentary government, elected by universal suffrage, drifted into oligarchy and finally into a military dictatorship under Carlos Ibanez in 1924. Constitutional government was restored in 1932. The Christian Democratic government of Eduardo Frei (1964-70) inaugurated major reforms, including land redistribution, education, and far-reaching social and economic policies. A Marxist government under Salvador Allende lasted from 1970 to 1973 when the present military government of General Pinochet Ugarte took power, overthrew Allende, abolished the Congress, and banned political parties. It has moved the country in the direction of a free market economy but at the cost of systematic violations of human rights. A new constitution was promulgated in 1981, and congressional elections have been scheduled for October, 1989. A "National Accord for Transition to Full Democracy" was mediated by the Catholic Church in 1985. The social reforms of the

    In 1985, Chile's population stood at 12 million, with an annual growth rate of 1.7%. 1984's infant mortality rate was 20/1000 live births and life expectancy was 67 years. The literacy rate was 94%. Of the work force of 3,841,000 in 1985, 15.9% were engaged in agriculture, forestry, and fishing; 31.3% were employed in industry and commerce; 38.6% were in the service sector; 8.7% worked in mining; and 4.4% were employed in construction. Chile's military junta is scheduled to be replaced by an elected legislature in 1990. The GDP was US $19.2 billion in 1984, with an annual real growth rate of 6.3%, and per capita GDP stood at US$1590. Inflation averages 23%. Industry comprises 21% of the GDP. Longterm prospects for the Chilean economy are influenced by a high debt service ratio, very low domestic savings and investment, the prospect of little or no increase in copper prices, and continuing problems in the domestic financial sector. In 1985-88, under the International Monetary Fund macroeconomic program, Chile will strive for moderate economic growth while managing its external debt servicing burden. PMID:12178144

    2014-08-01

    According to recent surveys, there is a high prevalence of domestic violence (DV) in Chile. A systematic review was conducted in PubMed, Scielo, and Lilacs with the MesH terms "Chile", "Mental Health", "Health", "Domestic Violence", to explore the impact of DV on health in Chile. Eleven studies fulfilled the inclusion criteria. Two studies were prospective, exploring the influence of DV on maternal-infant health. Nine studies explored the influence of DV on mental health in adults. DV was associated with deranged mental health indicators specially anxiety and depressive symptoms and suicidal ideation. Similar results were observed among mothers who were victims of violence and their children. It is concluded that DV is a complex phenomenon with serious effects on health. However the number of studies on the subject is low and new follow up studies are required. Predictive models for DV and effective preventive measures are urgently needed. PMID:25424674

Its copper reserves are also the most important on the planet. However, after years of mineral exploitation, the ease of extracting copper oxides and ore copper content has diminished. To keep the production level high, the introduction of new technologies has become necessary. One that has been successful is bioleaching. Chile had the first commercial operation in the world exclusively via bioleaching copper sulfides. Nowadays, all bioleaching operations run in the country contribute to an estimated 10% of total copper production. This article presents antecedents that have contributed to the development of copper bioleaching in Chile.

    International Nuclear Information System (INIS)

    The main radioactive waste management issues to be faced by the Chilean Nuclear Energy Commission (CCHEN) are discussed herein. Research reactor spent fuel management is the most outstanding challenge at the beginning of the 21st century. Interim storage appears to be the most promising alternative, allowing fuel safekeeping until a definitive step is taken. The situation regarding radioactive waste resulting from radioisotope applications in Chile will not undergo considerable change in the near future. Low and intermediate level radioactive waste management is being safely performed followed by interim storage of conditioned wastes. The strategy in the radioactive waste management plan, to be described as well, is meant to ensure the safe storage of radioactive wastes produced in Chile. (author)

    The author describes a joint program to use renewables for rural electrification projects in Chile. The initial focus was in a limited part of the country, involving wind mapping, pilot project planning, training, and development of methodologies for comparative evaluations of resources. To this point three wind hybrid systems have been installed in one region, as a part of the regional private utility, and three additional projects are being designed. Additional resource assessment and training is ongoing. The author points out the difficulties in working with utilities, the importance of signed documentation, and the need to look at these programs as long term because of the time involved in introducing such new technologies.

    ESO, the European Southern Observatory, in reply to questions raised by the international media, as well as an ongoing debate about the so-called "Paranal case" in Chilean newspapers, would like to make a number of related observations concerning its status and continued operation in that country [1]. THE ESO OBSERVATORY SITES IN CHILE The European Southern Observatory, an international organisation established and supported by eight European countries, has been operating more than 30 years in the Republic of Chile. Here ESO maintains one of the world's prime astronomical observatories on the La Silla mountain in the southern part of the Atacama desert. This location is in the Fourth Chilean Region, some 600 km north of Santiago de Chile. In order to protect the La Silla site against dust and light pollution from possible future mining industries, roads and settlements, ESO early acquired the territory around this site. It totals about 825 sq. km and has effectively contributed to the preservation of its continued, excellent "astronomical" quality. Each year, more than 500 astronomers from European countries, Chile and elsewhere profit from this when they come to La Silla to observe with one or more of the 15 telescopes now located there. In 1987, the ESO Council [2] decided to embark upon one of the most prestigious and technologically advanced projects ever conceived in astronomy, the Very Large Telescope (VLT). It will consist of four interconnected 8.2-metre telescopes and will become the largest optical telescope in the world when it is ready. It is safe to predict that many exciting discoveries will be made with this instrument, and it will undoubtedly play a very important role in our exploration of the distant universe and its many mysteries during the coming decades. THE VLT AND PARANAL In order to find the best site for the VLT, ESO performed a thorough investigation of many possible mountain tops, both near La Silla and in Northern Chile. They showed

  5. The biomethane potential in Chile

    International Nuclear Information System (INIS)

    Within the last decade natural gas gained considerable importance in Chile. The contribution of natural gas within the energy system will increase in the future by predicted 3.6% annually until the year 2015. Due to limited resources within its own country, the energy system of Chile depends on natural gas imports preferential from Argentina. Therefore, the aim of several stakeholders from policy and industry is to reduce the share of imported primary energy within the overall energy system. In order to reach this goal, the use of domestic resources and particularly the utilisation of biomass as one of the most important renewable sources of energy in Chile could play an important role. Against this background, the goal of this paper is the analysis of the technical potentials of biomethane as a substitute for natural gas. For the production of biomethane the anaerobic or bio-chemical (i.e. Biogas) as well as the thermo-chemical conversion pathways (i.e. Bio-SNG) are considered. The results of this analysis show that biomass converted to biomethane is a promising energy provision option for Chile and it contributes to the reduction of greenhouse gas emissions

    1993-12-01

    Aiming to describe the place that Chile has in the epidemiological transition, a descriptive study of the changes in demographic and epidemiological profiles of the country during the last 30 years is presented. The important decrease in general and child mortality rates, that has lead to an increase in life expectancy and ageing of the population, is emphasized. A 82% reduction in the proportion of deaths among less than one year old children and a 62% increase in mortality among people 65 years or older is observed. In agreement with these changes, non transmissible chronic diseases appear as the principal cause of mortality (65% of all deaths). However, regarding morbidity, an increase in digestive infectious and sexually transmitted diseases and a decrease in immuno-preventable diseases, excepting measles, is noted. It is concluded that, according to mortality, Chile is in a post transition stage, but there is persistence of some infectious diseases, typical of a pre-transition stage. PMID:8085073

Es este trabajo se observa el mismo problema pero desde la perspectiva recientemente esbozada por los movimientos sociales: la del racismo ambiental o la desigual distribución de los deshechos del desarrollo y el consumo. De esta manera se revisan sucintamente los principales conflictos que han surgido en el último tiempo a lo largo del país entre empresas públicas y privadas y comunidades locales y originarias. Así mismo se examinan las formas de organización que estas últimas han asumido y el estado actual de articulación entre ellas. De la revisión de la situación se concluye que estamos ante el surgimiento de un actor de nuevo tipo, que surge de las contradicciones del Chile neoliberal y que se diferencia del movimiento ecologista por vincular sus reivindicaciones a la defensa del territorio y al derecho a la autodeterminación de los pueblos.

    In recent years, a new emphasis has been placed on increasing solid fuel availability in Chile, to reach the northern mining operations where demand for power is soaring. The south of the country is well served by hydroelectric power plants (2.3 million kW). The coal industry has doubled its capacity to cope with increased copper production - the Tocopilla power plant at the Chuquicamata copper mine has been converted from oil to coal - and there has been a major investment programme in the steel industry. In 1986, 1.4 million tons of coal was mined, mostly from the Provinces of Concepcion and Arauco, the remainder from Valdivia. Since then, 70 million US dollars has been invested by COCAR SA in the Pecket deposit near Punta Arenas. Coal from Pecket should cost around 26 dollars/t compared with 60 dollars/t for underground coal. It should support an expanded coal market in Chile and may also be able to compete in the Brazilian and Argentine markets. Reserves are estimated at over 200 Mt. Petroleum reserves in Tierra del Fuego are nearly exhausted; seismic surveys in the Atacama desert are promising.

    Full Text Available El Bicentenario de la República de Chile se conmemoró en el mes de septiembre del año 2010. Además de marcar un importante hito histórico, coincidió con un cambio político en el Gobierno del país, el que pasó de la Concertación de Partidos por la Democracia a la Alianza de partidos formada por la derecha chilena. Se cumplieron por tanto 20 años desde que en el año 1990 cambiara el Gobierno militar presidido por el general Pinochet. Ese largo tiempo, dos décadas, coincide con un período de políticas que el Estado ha implementado hacia los Pueblos Indígenas. El Proyecto “Conmemoraciones y Memorias Subalternas” ha realizado durante el año 2010 un conjunto de investigaciones de terreno y documentales tendientes a comprender del modo más objetivo y científico lo ocurrido en el período y por tanto la situación actual de las sociedades mapuches en sus complejas relaciones con la chilena.O Bicentenario da República do Chile comemorou-se no mês de Setembro do ano 2010.

  20. Village microgrids: The Chile project

    Energy Technology Data Exchange (ETDEWEB)

    Baring-Gould, E.I.

    1997-12-01

    This paper describes a village application in Chile. The objective was to demonstrate the technical, economic and institutional viability of renewable energy for rural electrification, as well as to allow local partners to gain experience with hybrid/renewable technology, resource assessment, system siting and operation. A micro-grid system is viewed as a small village system, up to 1200 kWh/day load with a 50 kW peak load. It can consist of components of wind, photovoltaic, batteries, and conventional generators. It is usually associated with a single generator source, and uses batteries to cover light day time loads. This paper looks at the experiences learned from this project with regard to all of the facets of planning and installing this project.

  4. Biomonitoring air pollution in Chile

    International Nuclear Information System (INIS)

    Full text: Chile, in general, and Santiago, its capital city, in particular, has serious air pollution problems mainly in winter time when the pollutants could reach dangerous levels which might be detrimental to older people and children. A project was undertaken within the framework of a Co-ordinated Research Programme (CRP) supported by the International Atomic Energy Agency (IAEA) to carry out a long term study on atmospheric air pollution in Chile using biomonitors. The present paper describes the activities carried out within this CRP. The lichens, collected in clean areas (native forests), were transplanted to selected sites in Santiago and exposed during three and six months. At a second stage, samples of Tillandsia recurvata were collected in the Metropolitan Area. All samples were carefully cleaned, using only clean plastic materials, milled at liquid nitrogen temperature, freeze dried, re-homogenized and stored at low temperature until analysis. The samples were mainly analysed by INAA, RNAA SS-AAS and ASV. As part of the routine QA/QC programme, analytical laboratories involved in the project participated in intercomparison runs organized by the IAEA for the determination of trace and minor elements in two lichens samples. From the data and its subsequent mapping over the area under study, it was possible to identify places exposed to higher amounts of some elements. Of interest are also the correlations between several elements, perhaps indicating a given source of pollutants. The results indicate the usefulness of biomonitoring air pollution using lichens and Tillandsias, which, jointly with multielemental analytical techniques, such as NAA, open the possibility to study extensive areas without the infrastructure needed for conventional APM sample collection and at reduced costs.

  7. Chile ushers in new hydro era

    International Nuclear Information System (INIS)

    The planned construction of two hydroelectric power plants at Peuchen and Mampil, will help to meet Chile's growing electricity demand. Securing finance for the project has been straight forward thanks to the optimal hydrological conditions, rivers with a very strong flow providing a large head of water over short distance. Hydropower plays a central role in Chile's generating capacity providing 70% of total energy consumption. Thus, the future of these projects will be highly successful, it is argued. (UK)

    Despite success in reducing poverty over the last twenty years, inequality in Chile has remained virtually unchanged, making Chile one of the least equal countries in the world. High levels of inequality have been shown to hamper further reductions in poverty as well as economic growth and local inequality has been shown to affect such outcomes as violence and health. The study of inequality at the local level is thus crucial for understanding the economic well-being of a country. Local measu...

    While some countries have unbundled distribution and retailing, skeptics argue that the physical attributes of electricity make retailers redundant. Instead, it is claimed that passive pass through of wholesale prices plus regulated charges for transmission and distribution suffice for customers to benefit from competitive generation markets. We review the Chilean experience with regulated retailing and pass through of wholesale prices. We argue that when energy wholesale prices are volatile and prices are stabilized, distortions emerge. Regulated retailers gain little by mitigating or correcting them. On the contrary, sometimes price distortions increase their profits. We estimate the cost of three distortions that neither regulated retailers nor the regulator have shown any interest in correcting. - Highlights: > We review Chile's experience with regulated electricity retailing. > Distortions emerge when energy wholesale prices are volatile and prices stabilized. > Regulated retailers gain little by mitigating or correcting distortions. > Sometimes price distortions increase retailers' profits. > We estimate the cost of three distortions, which retailers have not corrected.

  12. Isotope hydrology in northern Chile

    International Nuclear Information System (INIS)

    Environmental isotope analyses were done on samples from aquifers in the Pampa del Tamarugal and the Salar de Atacama drainage basin in northern Chile. In the Pampa it is possible to delineate individual groundwater bodies on the basis of their 18O and deuterium contents and, in some cases, to relate these to specific recharge areas. A marked displacement from the meteoric water line indicates that river recharge is an important mechanism for groundwater renewal. Groundwater ages appear high at distance from the Andes and much of the water found in the Pampa may have to be treated as a non-renewable resource. The groundwaters, springs and rivers of the Salar de Atacama drainage basin vary between -6.09 and -8.06%. No difference between the different waters can be recognized and an evaporative isotope enrichment indicates that also here river recharge is an important process. Some groundwaters adjacent to the Salar are very salty but 18O and deuterium data show that these waters are not refluxed brines but simply salty freshwater. The 14C contents in groundwaters and springs are very low but their delta13C values are high. It is concluded that this is probably due to the uptake of volcanic CO2. 14C age dating is thus not possible unless the delta13C values of all possible carbon sources can be defined and the geochemical evolution of the groundwaters is better understood.

  14. Radioactive wastes management development in Chile

    International Nuclear Information System (INIS)

    A Facility for immobilizing and conditioning of radioactive wastes generated in Chile, has recently started in operation. It is a Radioactive Wastes Treatment Plant, RWTP, whose owner is Comision Chilena de Energia Nuclear, CCHEN. A Storgement Building of Conditioned Wastes accomplishes the facility for medium and low level activity wastes. The Project has been carried with participation of chilean professionals at CCHEN and Technical Assistance of International Atomic Energy Agency, IAEA. Processes developed are volume reduction by compaction; immobilization by cementation and conditioning. Equipment has been selected to process radioactive wastes into a 200 liters drum, in which wastes are definitively conditioned, avoiding exposition and contamination risks. The Plant has capacity to treat low and medium activity radioactive wastes produced in Chile due to Reactor Experimental No. 1 operation, and annex Laboratories in Nuclear Research Centers, as also those produced by users of nuclear techniques in Industries, Hospitals, Research Centers and Universities, in the whole country. With the infrastructure developed in Chile, a centralization of Radioactive Wastes Management activities is achieved. A data base system helps to control and register radioactive wastes arising in Chile. Generation of radioactive wastes in Chile, has found solution for the present production and that of near future

  7. Thermoluminescence properties of Chile Guajillo (paprika) Mexicano

    International Nuclear Information System (INIS)

    The thermoluminescence properties of the inorganic dust extracted from the Chile Guajillo (paprika) Mexicano, were studied in order to verify the possibility of using the TL technique to discriminate between irradiated and non irradiated peppers. The inorganic dust was found to consist of quartz 60%, albite (NaAlSi3O8) 30%, and ortose (KAlSi3O8) 10%. Its thermoluminescence dose response covers the wide dose range of 1Gy-10kGy, which was attributed mainly to feldspars. Its high sensitivity and its stability over 10 irradiation-readout cycles allow the application of a single grain-single aliquot regeneration dosimetry in Chile Guajillo (paprika). Evaluations based on trapping parameters show that thermal fading at room temperature for glow-peaks above 180 deg.. C, is not a problem in the dosimetry of paprika

  14. Radiological protection in interventional cardiology in Chile

    International Nuclear Information System (INIS)

    In September 2000, an expert mission was assigned to Chile, under the regional project named 'International BBS in Medical Practices Radiation Protection and Quality Assurance In Interventional Radiology' (ARCAL XLIX). The objective of the mission was to evaluate the level of radiation protection (RP) and safety in interventional cardiology ( IC ) installations. A team of local cardiologists, medical physicists and technologists was created for this purpose and during one week, several cardiology laboratories were evaluated and some basic quality controls (QC) were carried out. A basic pilot training course in radiation protection was imparted at the Hospital of the University of Chile in Santiago de Chile and some of the key objectives for a future national quality assurance programme were presented during the national congress of IC. In addition, a national survey on radiation protection aspects was circulated and its results evaluated. These activities enabled the local team to become familiar with the methodology of assessment of the level of protection and the organization of a programme, which was illustrated with the examples of similar European programmes. As result of these actions, several proposals were made to both the local authorities and the IAEA. The most important were: a) to initiate a basic QC programme, b) to organize a training in RP for cardiologists in order to formalize their accreditation, c) to improve personal occupational dosimetry, d) to initiate a programme of patient dosimetry, e) to optimize the technical and clinical protocols, f) to create a national registry of incidents with skin injuries.

  4. Forest mapping with satellite in Chile

    Chile has about 9.1 million ha of forest land, among which 7.6 million ha are native forest and 1.5 million ha are plantations of exotic species. The number of plantations is constantly growing due to the important role these areas play in the national economy. Pino Radiata (Pinus radiata) is found in most of the plantations while the remaining parts are dominated by Eucalyptus (Eucalyptus spp.) The governmental Instituto Forestal (INFOR) in Santiago de Chile, is monitoring the rapid changes in these areas through frequent inventories. As an inventory of this type takes about six years to complete in all areas (one region per year), it is of great importance to find quicker ways to cover these areas. The native forest has in recent years been the subject of debate, not only for economic reasons, but also as a result of ecological pressure for conservation. Where to conserve, where to put restrictions and where to allow forestry are the big issues. Against this background it is necessary to evaluate different data sources that can give information about the present forest situation and provide the means to monitor the changes. The aim of the project was to evaluate whether satellite imagery could fulfill INFOR`s demand for forestry information, and to investigate the kind of data source and methodology to apply when using satellite data

  5. The ecology of Chagas disease in Chile.

    Schofield, C J; Apt, W; Miles, M A

    1982-01-01

    Chagas disease probably affects over half a million people in Chile, principally in rural communities in the fertile valleys of the arid 'norte chico' region, north of Santiago. The main domestic vector is Triatoma infestans, but Triatoma spinolai, although mainly in rocky sylvatic and peridomestic ecotopes, also invades houses. Since the Spanish invasion in the sixteenth century, and particularly during the last 100 years, the endemic region has suffered an ecological breakdown, largely due to excessive timbering and over-grazing, which has led to a denuded landscape with severe loss of agricultural productivity. This breakdown, combined with uneconomically sized farms and poor marketing, exacerbates the poverty of the rural communities. As in other similar areas of Latin America, the combination of poverty and poor education discourages improvements in housing which would reduce the risk of vector-transmitted Chagas disease. This paper reviews the historical and ecological background of the endemic region of Chile, both as a basis for further work, and as a point of comparison with other endemic areas. The review attempts to show how the current status of Chagas disease is likely to be maintained through its association with poor quality housing, poverty and ecological degradation, drawing parallels with other endemic++ areas and suggesting ways by which the ecological damage might be reversed.

    ESO and the Government of Chile launched today the book "10 Years Exploring the Universe", written by the beneficiaries of the ESO-Chile Joint Committee. This annual fund provides grants for individual Chilean scientists, research infrastructures, scientific congresses, workshops for science teachers and astronomy outreach programmes for the public. In a ceremony held in Santiago on 19 June 2006, the European Organisation for Astronomical Research in the Southern Hemisphere (ESO) and the Chilean Ministry of Foreign Affairs marked the 10th Anniversary of the Supplementary Agreement, which granted to Chilean astronomers up to 10 percent of the total observing time on ESO telescopes. This agreement also established an annual fund for the development of astronomy, managed by the so-called "ESO-Chile Joint Committee". ESO PR Photo 21/06 ESO PR Photo 21/06 Ten Years ESO-Chile Agreement Ceremony The celebration event was hosted by ESO Director General, Dr. Catherine Cesarsky, and the Director of Special Policy for the Chilean Ministry of Foreign Affairs, Ambassador Luis Winter. "ESO's commitment is, and always will be, to promote astronomy and scientific knowledge in the country hosting our observatories", said ESO Director General, Dr. Catherine Cesarsky. "We hope Chile and Europe will continue with great achievements in this fascinating joint adventure, the exploration of the universe." On behalf of the Government of Chile, Ambassador Luis Winter outlined the historical importance of the Supplementary Agreement, ratified by the Chilean Congress in 1996. "Such is the magnitude of ESO-Chile Joint Committee that, only in 2005, this annual fund represented 8 percent of all financing sources for Chilean astronomy, including those from Government and universities", Ambassador Winter said.

    Bringing together more than 170 years of data, this study represents the first attempt to construct a species checklist and analyze the diversity and distribution of testate amoebae in Chile, a country that encompasses the southwestern region of South America, countless islands and part of the Antarctic. In Chile, known diversity includes 416 testate amoeba taxa (64 genera, 352 infrageneric taxa), 24 of which are here reported for the first time. Species-accumulation plots show that in Chile, the number of testate amoeba species reported has been continually increasing since the mid-19th century without leveling off. Testate amoebae have been recorded in 37 different habitats, though they are more diverse in peatlands and rainforest soils. Only 11% of species are widespread in continental Chile, while the remaining 89% of the species exhibit medium or short latitudinal distribution ranges. Also, species composition of insular Chile and the Chilean Antarctic territory is a depauperated subset of that found in continental Chile. Nearly, the 10% of the species reported here are endemic to Chile and many of them are distributed only within the so-called Chilean biodiversity hotspot (ca. 25° S-47° S). These findings are here thoroughly discussed in a biogeographical and evolutionary context. PMID:26340665

    Fifteen cases of human pseudoterranovosis are reported for Chile, representing an emerging parasitic infection in this country caused by larvae of the nematode Pseudoterranova sp. Our observations also included an outbreak of pseudoterranovosis in 3 of 4 individuals who shared the same raw fish dish (cebiche). Most of the cases occurred in adult patients. The main source of infection was from consumption raw or fried marine fish, including hakes (Merluccius australis or Merlucciuts gayi), pomfret (Brama australis), Inca scad (Trachurus murphvi), and corvina (Cilus gilberti). Seasonal distribution showed most of the cases to occur in fall and spring. Parasite larvae were isolated from the mouths of most of the patients after they reported a pharyngeal tickling sensation, coughing, vomiting, or a foreign body in the mouth or throat. PMID:17539437

  1. The fruit fly programme in Chile

    International Nuclear Information System (INIS)

    Full text: country. In fact, no species of the genera Ceratitis, Bactrocera, Anastrepha, Dacus and Toxotrypana exist in the country. This programme uses the Fruit fly National Detection System, which includes detection of the pest by trapping and fruit sampling in different areas located between the I and XI Regions of the country. This system is approved by the Chilean trade partners on the basis of the fruit fly-free recognition. For the Chilean fresh fruit exports, this is an important advantage, because there is no need to apply quarantine treatments or any other restriction measure. Chile has also a huge fruit industry, whose export revenues last season reached USD 1,900 million. This fact has permitted to undertake continuously a big effort to maintain that phytosanitary condition. Since Chile is the only fruit-fly free Latin American country, it has to face a continuous biological pressure of fruit flies, mainly C. capitata, to invade its territory. But the country has also some important advantages to prevent flies migrating due to its natural isolation. These natural barriers are the Los Andes ranges in the east, thousands of kilometers of desert in the north, the Pacific Ocean in the west and finally an extremely cold, sub polar climate in the south. This isolation has led to the NPPO officials to believe that the passive spread, through smuggling and hidden fruit in passenger's baggage, to be the most likely source of fruit fly entries. Because of that, Chile has a very strict quarantine system with border control stations at every point of entry. The only exception to the mentioned isolation is Arica Province on the border with Peru. There, SAG applies an area-wide preventative approach through the rearing and release of sterile insects, as well as bait spraying in the border area, which is mainly desert, but has some 'green spots' that allow the fly to alight for resting and feeding. Additionally, through bi-national agreements, common activities are

    2014-01-01

    Chile is recognized worldwide as an emergent economy, with a great power in natural resource exploitation. Nonetheless, despite being one of the most developed countries in Latin America, Chile imports most of the knowledge and technology necessary to drive innovation in the country. The tight budget that the Chilean government assigned to research and development and the absence of a long-term scientific agenda contributed to a limited supply of scientists over the years. In an effort to reverse this scenario, Chile has created several fellowships, such as the Becas Chile Program (BCP) to encourage new generations to pursue graduate studies to ultimately advance research and development in situ. More than 6000 fellows are now being trained abroad, accumulating an incredible potential to transform the Chilean scientific environment as we know it.  Chile now faces a greater challenge: it has to offer infrastructure and job openings to the highly skilled professionals in whom it invested. Unfortunately no clear public policies to address this situation have been developed, partially due to the lack of a dedicated institution, such as a Ministry for Science and Technology which could focalize the necessary efforts to promote such policies. Therefore, in the meantime, Chilean scientist have been motivated to create different organizations, such as, Mas Ciencia para Chile and Nexos Chile-USA, to promote constructive discussion of the policies that could be implemented to improve the Chilean scientific situation. We hope that these and other organizations have a real impact on the generation of scientific guidelines that will finally contribute to the development of the country. PMID:25309739

    Full Text Available This paper describes the origin and evolution of two Chilean political parties (the Radical Party and the Christian Democrat Party through the analysis of the social networks that originated and composed them. The aim of this study is to propose a model of national political cultures on the basis of the structure of social networks related to power and of the symbol system, which legitimizes it. The structure of social networks, horizontal and vertical, are based on reciprocal or redistributive forms of exchange, on what is being exchanged and on the articulation between networks. In every society there are symmetrical and asymmetrical exchanges, which produce horizontal and vertical networks. These networks interact among themselves to form the social fabric. The dominance of some over others and how they combine, delineate the character of the political culture (authoritarian vs. egalitarian. Chile is a multiparty country within which there are cohorts of horizontal groups of friends, who informally exercise a central control over their members and create invisible boundaries setting them apart from others, in which leadership is under constrains. The result is both a strong presidential system based on an almost fanatic legitimacy, combined with factionalism and a strong parliamentary system.

    High-bandwidth communication has become a key factor for scientific installations as Observatories. This paper describes the technical, organizational, and operational goals and the level of completion of the ALMA Optical Link Project. The project focus is the creation and operation of an effective and sustainable communication infrastructure to connect the ALMA Observatory, located in the Atacama Desert, in the Northern region of Chile, with the point of presence in ANTOFAGASTA, about 400km away, of the EVALSO infrastructure, and from there to the Central Office in the Chilean capital, Santiago. This new infrastructure that will be operated in behalf of ALMA by REUNA, the Chilean National Research and Education Network, will use state of the art technologies, like dark fiber from newly built cables and DWDM transmission, allowing extending the reach of high capacity communication to the remote region where the Observatory is located. When completed, the end-to-end Gigabit-per-second (Gbps) capable link will provide ALMA with a modern, effective, robust, communication infrastructure capable to cope with present and future demands, like those coming from fast growing data transfer to rapid response mode, from remote monitoring and engineering to virtual presence.

    The purpose of the present study was to determine the protein quality and digestibility of shellfish commonly consumed in Chile, and to estimate its contribution to the protein needs of the Chilean population. The shellfish studied were chorito (Mytilus edulis chilensis), macha (Mesodesma donacium), loco (Concholepas concholepas), cholga (Aulacomya ater), erizo (Loxechinus albus) and almeja (no specific variety). The NPU method was used to determine protein quality. The percentage of protein adequacy for adult rations was calculated according to FAO/WHO 1973. The contribution of shellfish to the protein availability according to the family income of the Santiago population, was also calculated. Most of the shellfish presented NPU values of about 70; the lowest values were found for loco (54.9) and macha (63.3). The apparent and true digestibility gave an average of 83.6 and 90.4, respectively. The percentage of protein adequacy of habitual rations ranged between 27% (erizo) and 58% (loco). The availability of shellfish protein in relation to total protein increased from 0.4 to 2.5% when income increased. It is concluded therefore, that shellfish protein is, in general, of good quality. Nevertheless, it might be considered of poor influence insofar as fulfilling the protein needs of the population studied, whatever its socioeconomic level. PMID:3834878

    Both Chile and Mexico experienced severe economic crises in the early 1980s, but Chile recovered much faster than did Mexico. Using growth accounting and a calibrated dynamic general equilibrium model, we conclude that the crucial determinant of this difference between the two countries was the faster productivity growth in Chile, rather than higher investment or employment. Our hypothesis is that this difference in productivity was driven by earlier policy reforms in Chile, the most crucial ...

    Full Text Available DESENVOLVIMENTO DA EDUCAÇÃO PRÉ-ESCOLAR NO CHILEResumoA educação pré-escolar no Chile tem início na segunda metade do século 19, especialmente por influência alemã, trazida ao país por José Abelardo Núñez. No começo se deu de forma particular, formando-se os primeiros jardins de infância. Somente em 1906 foi fundado o primeiro jardim da infância mantido pelo Estado, anexo à Escola Normal n. 1. Para isso foi contratada a educadora austríaca Leopoldina Maluschka, que usou metodologias inspiradas em Fröebel. Na Universidad de Chile, a partir da década de 1930, teve início um movimento de renovação pedagógica orientado por Irma Salas, que havia se doutorado nos Estados Unidos com Dewey e trouxe o pensamento da Escola Nova para o país. Ela conduziu a criação da Escola de Educadoras de Pré-Escolares em 1944. A primeira diretora dessa escola foi a destacada professora Amanda Labarca. Isto facilitou a criação de berçários e creches no país. Neste texto, de caráter histórico, em que se recorrerá a documentos primários e secundários, se pretende descrever o desenvolvimento que o Estado do Chile tem mostrado pela educação pré-escolar no país, reconhecendo os direitos das crianças.Palavras-chave: jardins de infância, educação pré-escolar, Escola Nova, Junji/Integra. PRESCHOOL EDUCATION DEVELOPMENT IN CHILEAbstractPreschool education in Chile has its beginnings in the second half of the nineteenth century due to the German influence brought to Chile by José Abelardo Núñez.

  1. The National Immunization Plan for Chile: is it a priority?

    2012-12-01

    Full Text Available Since 1978, Chile has an expanded immunization program. Target population is all infants and children in the country, along with the elderly at age 65. If we review available World Health Organization data on the immunization monitoring system, in 2011 all vaccines had below 95% coverage. With the exception of BCG, vaccines are primarily applied in the primary care setting. One way to understand organizational priorities is to identify how present they are in the management systems. Thus, it is possible to determine the priority of the National Immunization Plan in Chile by looking into sectoral planning. A review of the most recent policy documents of the Ministry of Health of Chile, one titled “National Health Strategy to Achieve the Health Objectives of the 2011-2020 Decade" stands out. Upon reviewing this policy paper, the National Immunization Plan is not considered as an outcome as a whole, but only some of the vaccines it includes.

    Full Text Available Despite success in reducing poverty over the last twenty years, inequality in Chile has remained virtually unchanged, making Chile one of the least equal countries in the world. High levels of inequality have been shown to hamper further reductions in poverty as well as economic growth and local inequality has been shown to affect such outcomes as violence and health. The study of inequality at the local level is thus crucial for understanding the economic well-being of a country. Local measures of inequality have been difficult to obtain, but recent theoretical advances have enabled the combination of survey and census data to obtain estimators of inequality that are robust at disaggregated geographic levels. In this paper, we employ this methodology to produce consistent estimators of inequality for every county in Chile. We find a great deal of variation in inequality, with countylevel Gini coefficients ranging from 0.41 to 0.63.

    2009-06-01

    On 2 May 2008, a large eruption began unexpectedly at the inconspicuous Chaitén volcano in Chile's southern volcanic zone. Ash columns abruptly jetted from the volcano into the stratosphere, followed by lava dome effusion and continuous low-altitude ash plumes [Lara, 2009]. Apocalyptic photographs of eruption plumes suffused with lightning were circulated globally. Effects of the eruption were extensive. Floods and lahars inundated the town of Chaitén, and its 4625 residents were evacuated. Widespread ashfall and drifting ash clouds closed regional airports and cancelled hundreds of domestic flights in Argentina and Chile and numerous international flights [Guffanti et al., 2008]. Ash heavily affected the aquaculture industry in the nearby Gulf of Corcovado, curtailed ecotourism, and closed regional nature preserves. To better prepare for future eruptions, the Chilean government has boosted support for monitoring and hazard mitigation at Chaitén and at 42 other highly hazardous, active volcanoes in Chile.

    Full Text Available Por casi un siglo, varios autores han analizado los patrones de distribución de la fauna y flora marina del Pacífico de Sudamérica y de la costa de Chile en particular, con el propósito de establecer el número de las unidades biogeográficas presentes. Si bien los patrones generales actuales son relativamente bien conocidos, la mayoría de los estudios se ha enfocado en las discontinuidades distribucionales y en propuestas de clasificación más que en los factores y procesos dinámicos que han formado las unidades espaciales identificadas. Aun en el caso de las clasificaciones, las conclusiones publicadas se basan principalmente en el análisis de uno o pocos grupos seleccionados, y presentan diferencias importantes en los criterios de selección de los grupos, el número de especies involucrado y la metodología usada. Por otra parte, las discrepancias entre estudios específicos tienden a obscurecer un fenómeno relevante y de mayor escala como es la dinámica de las biotas, uno de los aspectos biogeográficos menos conocidos en Chile. En tal contexto, este trabajo presenta una revisión de literatura sobre la biogeografía marina de Chile y sus aspectos asociados, con los siguientes objetivos: (a resumir las características oceanográficas, climáticas y geomorfológicas de la costa continental de Chile; (b discutir 27 clasificaciones biogeográficas publicadas para la costa chilena, analizando los criterios y procedimientos usados por los autores, sus conclusiones principales, y la concordancia entre los estudios; (c evaluar los procesos dispersivos y vicariantes asociados a los desplazamientos y modificaciones de las biotas de la región, en función de los antecedentes disponibles sobre las condiciones existentes y los principales eventos ocurridos durante los períodos Terciario y Cuaternario; y (d proponer un escenario de cambio biogeográfico basado en determinantes históricas y su influencia en la formación, carácter y din

  5. Analysis and projections of physics in Chile

    International Nuclear Information System (INIS)

    In the present work, an assessment of the Physics research capacity in Chile is presented. For this, the period between 2000 and June 2005 has been studied. In this period almost 200 physicists have contributed to scientific production in terms of ISI publications. Amongst these 200, ∼160 correspond to theoretical physicists and only ∼40 to experimental physicists; ∼178 are men and only ∼22 are women. A more detailed analysis shows that ∼160 physicists have at least one appearance in ISI publications per year considering the last 3 years. Ten years ago, a similar criteria (at least one appearance per year in ISI articles, considering mobile three-year periods), the number of active physicists in the Chilean community was estimated at 70. Therefore, the Chilean active physicists' community has doubled in 10 years. There exist 20 centres in which scientific research is developed: 18 university centres, a government institute and a private institute. As regards scientific productivity, both as related to disciplines or research areas, and well as in relation to research centres, it is found that, generally, scientific production, in a particular area in Physics or in a research centre, is directly related to the number of corresponding researchers; that is to say, the percentage of the national productivity in an area or research centre corresponds to its share in the total number of physicists in the country. A geographical analysis shows that 50% of the productivity corresponds to Santiago and 50% to the rest of the country. The impact of the different funds for research is assessed, also: FONDECYT, Presidential Chairs and large projects and centres of excellence. According to Physics researchers opinion, Fondo Nacional de Ciencia y TecnologIa (FONDECYT, National Fund fro Science and Technology) has become the best instrument to support researchi activities in Chile. However, the amount of projects awarded has practically not been increased, which is

  7. Subduction zone guided waves in Northern Chile

    Garth, Thomas; Rietbrock, Andreas

    2016-04-01

    Guided wave dispersion is observed in subduction zones as high frequency energy is retained and delayed by low velocity structure in the subducting slab, while lower frequency energy is able to travel at the faster velocities associated with the surrounding mantle material. As subduction zone guided waves spend longer interacting with the low velocity structure of the slab than any other seismic phase, they have a unique capability to resolve these low velocity structures. In Northern Chile, guided wave arrivals are clearly observed on two stations in the Chilean fore-arc on permanent stations of the IPOC network. High frequency (> 5 Hz) P-wave arrivals are delayed by approximately 2 seconds compared to the low frequency (times of different frequencies, while the velocity spectra is used to constrain the relative amplitude of the arrivals. Constraining the waveform in these two ways means that the full waveform is also matched, and the low pass filtered observed and synthetic waveforms can be compared. A combined misfit between synthetic and observed waveforms is then calculated following Garth & Rietbrock (2014). Based on this misfit criterion we constrain the velocity model by using a grid search approach. Modelling the guided wave arrivals suggest that the observed dispersion cannot be solely accounted for by a single low velocity layer as suggested by previous guided wave studies. Including dipping low velocity normal fault structures in the synthetic model not only accounts for the observed strong P-wave coda, but also produces a clear first motion dispersion. We therefore propose that the lithospheric mantle of the subducting Nazca plate is highly hydrated at intermediate depths by dipping low velocity normal faults. Additionally, we show that the low velocity oceanic crust persists to depths of up to 200 km, well beyond the depth range where the eclogite transition is expected to have occurred. Our results suggest that young subducting lithosphere also has

    A combined analysis of terrigenous and biogenic compounds in marine sediments from the Chilean continental slope allows detailed reconstructions of both the paleoclimatic and paleoceanographic history of this region during the last glacial and Holocene. Based on sediment cores recovered during two cruises with the German R/V Sonne, we found evidence for changes both in continental rainfall, most likely induced by latitudinal shifts of the Southern Westerlies, and marine productivity as well as sea surface temperature (SST) changes within the Peru-Chile Current system on time scales ranging from Milankovitch to centennial-scale. On Milankovitch time-scales, we found strong evidence for precession-controlled shifts of the Southern Westerlies implying e.g. more humid conditions during the LGM in the Chilean Norte Chico and a trend towards more arid climates during the deglaciation culminating in the early Holocene. These shifts are paralleled by paleoceanographic changes indicating generally higher productivity during the LGM mainly caused by increased advection of nutrients from the south through an enhanced Peru-Chile current. SSTs off central Chile were about 3.5 C lower than present during the LGM. On shorter time-scales, extremely high resolution sediment cores from the southern Chilean margin provide evidence of significant short-term Holocene climate changes with bands of variability centred at ca. 900 and 1500 years, periodicities also well known from Northern Hemisphere records. Our data point to strong interhemispheric connections of climate change both on multi-centennial to millennial and Milankovitch time-scales with a major role of the tropics for the interhemispheric transfer of climate signals involving changes within the Hadley circulation and/or probably long-term modifications of the El Ni¤o-Southern Oscillation system. The recently drilled ODP Sites 1233 (ca. 41S) and 1234/1235 (ca. 36S) at the southern Chilean margin have the potential to extent

    The Chilean, Argentinean and Brazilian power matrixes presented in the last two decades a growth of the non-renewable energy sources share, especially fossil sources, mainly in installed capacity and in a lesser degree in energy production. Greenpeace and the European Renewable Energy Council have elaborated a reference energy scenario together with a scenario analyzing the institution of ample measures for the promotion of renewable energy sources. Feed-in tariffs and auction or bidding mechanisms implemented in Brazil and Argentina and the renewable portfolio standard implemented in Chile allied with the wind industry state in these countries indicate that Chile and Argentina will fulfill the 2020 wind power installed capacity predicted in the reference scenarios, while Brazil will reach the energy revolution scenario prediction. Important energy policy changes are required if the Chile and Argentina energy revolution scenarios wind power installed capacity are to become a reality in 2020. (author)

    The oceanic Nazca plate subducts beneath the continental South American plate by recurrent rupture of large segments of its interface. The resulting earthquakes are among the largest and most frequent on Earth. Along the Chilean and southern Peruvian margin, all sizeable segments have ruptured at least once in the past 150 years for which there exist historic and/or instrumental records. The one segment that is most mature for re-rupture stretches for more than 500 km along the northernmost Chilean coast between roughly -23° and -18° latitude. It last broke in 1877 in a magnitude ~8.5 earthquake, triggering a major Tsunami. From the historical record, it has been known to have a recurrence cycle of approximately 110 years. The adjoining segments to the south and north broke rather recently in 1995 and 2001 in M>8 earthquakes and an M 7.7 earthquake intruded into the southern part of the seismic gap in 2007 between Antofagasto and Tocopilla. This makes northern Chile a unique natural laboratory to observe a subduction megathrust at various stages of its seismic cycle. For that purpose, installation of long-term observatories started in 2006 in a close cooperation of the Universidad de Chile (Santiago, Chile), the Universidad Catolica del Norte (Antofagasta, Chile), the Institut de Physique du Globe de Paris (France), and the GFZ German research Centre for Geosciences (Germany). Currently we are operating 17 modern seismological stations equipped with STS-2 broadband seismometers and accelerometers (EPI sensor). At least two more stations will be installed in the near future. Continuous GPS, tilt, creep, climate and magnetotellurics measurements are complementing the seismological part. A majority of the sites provide data near real-time. We will present results of seismic monitoring including analysis of the 2007 M7.7 Tocopilla earthquake sequence that was recorded during the installation stage of the observatory. We relocated the mainshock and about a one

    Full Text Available This piece begins with a brief discussion of the concepts leading to the social right to health protection. Special emphasis is placed on the principle of social cohesion, which has influenced social health protection in European countries. Chile’s experience in this field from the 1990s to the present is described, as exemplified in three dimensions. In the first place, social security coverage is presented as a means to achieve universal (horizontal coverage. A discussion follows on vertical coverage, where the author identifies health problems for which insured persons have guaranteed rights of access to medical care. This section describes available emergency care, primary health care, and the special plan for Universal Access to Explicit Guarantees (Acceso Universal de Garantías Explícitas de salud, or AUGE. Thirdly, the discussion covers the funding sources supporting the Chilean health care system: Government subsidies, contributions to social security, and out-of-pocket disbursements for private care. Chile’s public health system has various special programs. One of them is catastrophic insurance, which covers 100% of the care needed for complex and very costly treatments. Older persons (over 65 have coverage for 100% of the cost of eyeglasses and hearing aids, and for 50% of the cost of home care. If life expectancy is an appropriate indicator of health system results, it is worth noting that Chile and the United States of America have both achieved a life expectancy of 77 years, even though Chile spends only 5.9% of its gross domestic product on health care, as compared to the 15% spent by the United States.

In 1998, the National Television of Chile, with the sponsorship of the College of Architects of Chile, requested preliminary architectural designs in order to enlarge and to renovate its headquarters buildings in Santiago, Chile in stages. The Acoustic Project has been developed in an integral way, with three fundamental disciplines: noise and noise control; Machine rooms; vibrations and vibration control; Buildings, engines; architectural acoustics and acoustic comfort; TV studios and technical rooms. This presentation describes the Acoustic Project, phases I (1999), and II (2002), how it was possible to establish a common language with architects and engineers and the different specialties, to apply acoustic criteria and standards, the theoretical development and the projected acoustic solutions.

    Espinoza, Manuel Antonio; Cabieses, Báltica; Paraje, Guillermo

    2014-01-01

    Health research is considered an essential element for the improvement of population health and it has been recommended that a share of the national health budget should be allocated to develop this field. Chile has undertaken efforts in the last decades in order to improve the governmental structure created to promote the development of health research, which has increased human resources and funding opportunities. On the other hand, the sustained economic growth of Chile in the last decades suggests that the health expenditure will maintain its increasing trend in the following years. This additional funding could be used to improve coverage of current activities performed in the health system, but also to address the incorporation of new strategies. More recently, health technology assessment (HTA) has been proposed as a process to support decisions about allocation of resources based on scientific evidence. This paper examines the relationship between the development of health research and the HTA process. First, it presents a brief diagnosis of the situation of health research in Chile. Second, it reviews the conceptual basis and the methods that account for the relationship between a HTA process and the development of health research. In particular, it emphasizes the relevance of identifying information gaps where funding additional research can be considered a good use of public resources. Finally, it discusses the challenges and possible courses of action that Chile could take in order to guarantee the continuous improvement of an articulated structure for health research and HTA.

  12. Oil and Gas Emergency Policy: Chile 2012 update

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    2012-09-06

    Chile has experienced several serious energy supply incidents over the last decade, including major droughts, a sustained gas supply cut from Argentina (since 2004), and a major earthquake in early 2010 which affected electricity networks and refineries, and caused several black-outs. Due to Chile's unique and sinuous geography - it runs 4 300 kilometres from North to South and only 175 kms from East to West- the country's energy markets are regionally disjointed, particularly as the regional gas and electricity grids are not connected. In the arid North, energy demand is dominated by the mining industry, and operates based on a separate thermal-based Sistema Interconectado Norte Grande (SING) electricity grid. The more densely-populated central region (including Santiago) operates on the more hydro-dependent Sistema Interconectado Central (SIC) electricity grid. The southernmost, hydro-rich regions of the country are not connected to the rest of Chile in terms of electricity and gas. The following report is based on an IEA Emergency Response Assessment carried out in 2010 and 2011 which looked specifically at Chile's capacity to respond to short-term emergencies in oil, gas and electricity.

    Observing sites at the East-Antarctic plateau are considered to provide exceptional conditions for astronomy. The aim of this work is to assess its potential for detecting transiting extrasolar planets through a comparison and combination of photometric data from Antarctica with time series from a midlatitude site. During 2010, the two small aperture telescopes ASTEP 400 (Dome C) and BEST II (Chile) together performed an observing campaign of two target fields and the transiting planet WASP-18b. For the latter, a bright star, Dome C appears to yield an advantageous signal-to-noise ratio. For field surveys, both Dome C and Chile appear to be of comparable photometric quality. However, within two weeks, observations at Dome C yield a transit detection efficiency that typically requires a whole observing season in Chile. For the first time, data from Antarctica and Chile have been combined to extent the observational duty cycle. This approach is both feasible in practice and favorable for transit search, as it i...

    Full Text Available En Chile continental la utilización de los crustáceos se remonta al menos a 10.200 años atrás. Sin embargo, la descripción formal de los componentes de la carcinofauna chilena se inició hace alrededor de 200 años, reconociéndose a Juan I. Molina como el primer naturalista nacional y el primero en asignar nombres científicos a crustáceos de este país. El desarrollo de la carcinología en Chile es obra de un vasto conjunto de especialistas extranjeros y nacionales. Entre los extranjeros destacan viajeros como el inglés Charles R. Darwin, quien contribuyó al conocimiento de los cirripedios; el francés Alcide D'Orbigny, primero en describir decápodos fósiles de Chile; y el alemán Eduard Poeppig, a quien se debe la temprana descripción de decápodos marinos y dulceacuícolas. Entre las expediciones extranjeras destacan la del buque británico H.M.S."Challenger", la de la Universidad de Lund (Suecia a Chile y la más reciente del B/I alemán "Victor Hensen" a Magallanes.

    1997-06-01

    Full Text Available This article examines two important educational reforms introduced since the return to democracy in Chile. The first one was targeted at the poorest 10% of schools in Chile. The second was a fundamental reform of the primary educational sector. Both have been successful in meeting their objectives, and mark a fundamental shift from the educational reforms of the Pinochet government. The reasons for the success of the reforms are broken down into political, institutional and operational factors. In essence, a small team of trained educational reformers, with widespread support and strong backing from the Minister of Education and the President were able to overcome the resistance of the bureaucrats of the Ministry of Education and that of the school teachers union.

    A study of television was conducted in Chile in 1971. There is a discontinuous aspect in the requests of the public, especially in times of crisis and rupture with the traditional order. In order to measure the various levels of appreciation and critique raised by the television in various areas of the working class in Chile, the poblaciones (peripheric residential zones) were chosen as the place for the study. 100 interviews were conducted. 60% of the people questioned were sympathizers or militants of the various left wing parties; the other 40% were sympathizers or militants of the opposition (Christian democracy, National party and right wing of the radical party). Television does not make any distinction between the publics, but the public makes distinctions between the effects of television. Melodramas and detective programs have the largest adhesion in the popular public of Latin America. PMID:12261387

  5. International Uranium Resources Evaluation Project (IUREP) national favourability studies: Chile

    International Nuclear Information System (INIS)

    Chile has an area of 740,760 square kilometers. The capital is Santiago. The country is 4,183 km. long and ranges from 22.5 to about 354 km. in width. Its chief topographic features para]lei each other - the Coastal Range, Andes Mountains and Central Valley. The Coastal Range rises to 2,130 meters in the north, but averages from 610 to 700 meters high generally. The range plunges into the Pacific Ocean far south of Valparaiso and reappears in the southern archipelagic islands. The Andes extend along nearly the entire length of Chile and contain 100 volcanoes. Andean peaks range mostly from 3,000 to 6,700 meters in elevation. In southern Chile the Andes are lower, and contain about a dozen major lakes. The mountains disappear in Chilean Patagonia, but reappear at Cape Horn. The Central Valley lies between the Coastal Range and the Andes, being best defined in the midland region as a 64 to 72 km sloping plain. It is the Chilean heartland with three-quarters of the country's population. Salt basins are found over much of northern Chile in the very arid desert, while the region south of the Gulf of Reloncavi consists of unpopulated islands, fjords, channels and heavily forested mountains. The Strait of Magellan, the Tierra del Fuego archipelago and a flat grassland area make up the extreme southern end of the country. Much of Chile is subject to flash floods, earthquakes, volcanic eruptions, landslides and avalanches. In September 1976 the Comision Chilena de Energia Nuclear (CCEN) was given exclusive rights to negotiate contracts with private companies for the exploration, development and mining of uranium and other radioactive minerals. The new law provides the CCEN with considerable flexibility in the terms of the contracts. Pre-964 owners of uranium deposits may reach agreements with foreign companies to mine the uranium, but since 1964 all uranium has belonged to the state. Uranium produced in the country can only be exported after Chile's needs have been met. The

  18. Climate change and energy policy in Chile: Up in smoke?

    International Nuclear Information System (INIS)

    This paper provides an ex-post assessment of the climate and energy policy developments in Chile emerging from a neoliberal economic model, during the period 1971–2007. First, correlation and regression analyses were performed to analyse historical CO2 emissions as a product of demographic, economic and energy-wide drivers. Then I estimate indicators related to CO2 emissions, energy use and economic activity. In the light of empirical results, I identify policy instruments and structural issues. Finally, I present a comparative analysis of Chile and other Latin American countries. Statistical tests show that variability of CO2 emissions is explained mostly by GDP per capita (‘affluence’) than any other tested variable. Indicators show that the diversification and decarbonisation of the energy mix has been a major policy challenge. With two notable exceptions (hydro and natural gas), the CO2 intensity of the energy supply mix suggests no effective policies, while energy security crises triggered negative carbon effects and increased prices. No clear policies to promote energy efficiency can be identified until 2005. Explicit policy instruments to promote renewable energy are only recognised after 2004. The results strongly suggest that Chile lacked of policies to effectively decarbonise its energy–economy system. - Highlight: ► The first paper that quantitatively assesses key drivers of CO2 emissions in Chile. ► It examines energy and climate policy development during the period 1971–2007. ► GDP per capita (‘affluence’) is the main determinant of CO2 emissions. ► Diversification and decarbonisation of energy mix has been a major policy challenge. ► Policy approach under analysed period not suited for a low-carbon economy.

    Countries abundant in natural resources face the dilemma of how to manage this source of revenues. The recent boom in commodity prices put this issue at the top of the agenda in natural resource rich economies. Chile, for instance, is the largest copper producer in the world, supplying 43% of world copper exports. In 2007, the state-owned corporation, CODELCO, produced one third of total Chilean copper output and the revenues from its copper exports accounted for 16% of total fiscal revenues....

    Mortality rates for cervical cancer (CC) in Chile are higher than those of developed countries and it has an unequal socioeconomic distribution. The recognition of human papilloma virus (HPV) as the causal agent of cervical cancer in the early 80's changed the prevention paradigms. Current goals are to prevent HPV infection by vaccination before the onset of sexual activity and to detect HPV infection in women older than 30 years. This article reviews CC prevention and early detection methods, discusses relevant evidence to support a change in Chile and presents an innovation proposal. A strategy of primary screening based on HPV detection followed by triage of HPV-positive women by colposcopy in primary care or by cytological or molecular reflex testing is proposed. Due to the existence in Chile of a well-organized nationwide CC prevention program, the replacement of a low-sensitivity screening test such as the Papanicolau test with a highly sensitive one such as HPV detection, could quickly improve the effectiveness of the program. The program also has a network of personnel qualified to conduct naked-eye inspections of the cervix, who could easily be trained to perform triage colposcopy. The incorporation of new prevention strategies could reduce the deaths of Chilean women and correct inequities. PMID:25424677

  12. Revisiting the Source Process of the 2007 Tocopilla, Chile Earthquake

    2013-12-01

    We revisit the 2007 Mw 7.7 Tocopilla, Chile earthquake to create a finite fault kinematic source model based on the current best practices in data analysis and inversion methods. The data used to constrain the source model include both static GPS offsets and 1 Hz kinematic GPS time series, as well as interferograms which have been reanalyzed to remove tropospheric effects which can be quite significant in this region. Our inversion methodology is a Bayesian approach that uses only physics-based constraints on the rupture evolution, and which utilizes models of both the observational noise and the errors in our forward model to obtain the ensemble of all plausible rupture models which satisfy both the data and our a priori assumptions. This approach allows us to better understand which parts of the rupture process are well-constrained and which are not, and thus to better understand how the 2007 Tocopilla, Chile earthquake rupture fits into the sequence of large earthquakes which have been mosaicking the northern Chile subduction zone.

  13. Development of management system for fruit export from Chile

    International Nuclear Information System (INIS)

    The activities of agencies in the control of fruit quality and of phytosanitary aspects have considerably increased in the last four years, resulting in an improvement in the quality of fresh fruits exported from Chile to the USA and Europe. Most of the produce, requiring shipping times of 2 to 3 weeks, is being shipped in refrigerated vessels. The Fundacion Chile has helped this export industry not only by training field inspectors, capable of checking quality of fruit before it has been packed, but also by certifying this quality when required by the exporter or his overseas customer. Strict quarantine requirements in importing countries have imposed a number of restrictions and produce is fumigated either in Chile or in the port of import. It is suggested that before irradiation is applied to Chilean fruits for export one should: (a) evaluate its effect on quality, with special reference on maturity at harvest, (b) demonstrate quarantine efficacy to a standard accepted by importing countries, (c) solve logistical aspects, (d) evaluate application technique in dependence of different packagings, (e) make cost assessments and (f) work towards bilateral agreement regarding acceptance of treatment and of facilities.

  17. Field survey of the 16 September 2015 Chile tsunami

    Lagos, Marcelo; Fritz, Hermann M.

    2016-04-01

    On the evening of 16 September, 2015 a magnitude Mw 8.3 earthquake occurred off the coast of central Chile's Coquimbo region. The ensuing tsunami caused significant inundation and damage in the Coquimbo or 4th region and mostly minor effects in neighbouring 3rd and 5th regions. Fortunately, ancestral knowledge from the past 1922 and 1943 tsunamis in the region along with the catastrophic 2010 Maule and recent 2014 tsunamis, as well as tsunami education and evacuation exercises prompted most coastal residents to spontaneously evacuate to high ground after the earthquake. There were a few tsunami victims; while a handful of fatalities were associated to earthquake induced building collapses and the physical stress of tsunami evacuation. The international scientist joined the local effort from September 20 to 26, 2015. The international tsunami survey team (ITST) interviewed numerous eyewitnesses and documented flow depths, runup heights, inundation distances, sediment deposition, damage patterns, performance of the navigation infrastructure and impact on the natural environment. The ITST covered a 500 km stretch of coastline from Caleta Chañaral de Aceituno (28.8° S) south of Huasco down to Llolleo near San Antonio (33.6° S). We surveyed more than 40 locations and recorded more than 100 tsunami and runup heights with differential GPS and integrated laser range finders. The tsunami impact peaked at Caleta Totoral near Punta Aldea with both tsunami and runup heights exceeding 10 m as surveyed on September 22 and broadcasted nationwide that evening. Runup exceeded 10 m at a second uninhabited location some 15 km south of Caleta Totoral. A significant variation in tsunami impact was observed along the coastlines of central Chile at local and regional scales. The tsunami occurred in the evening hours limiting the availability of eyewitness video footages. Observations from the 2015 Chile tsunami are compared against the 1922, 1943, 2010 and 2014 Chile tsunamis. The

  16. On the generation of coastal lows in central Chile

    International Nuclear Information System (INIS)

    Previous studies of the coastal-low occurrences in central Chile have been aimed at the formulation of a conceptual model to explain observed features in connection with applied studies. The most prominent weather pattern associated with CL occurrences, (type A), coincides with the onset of a warm, middle-troposphere ridge over central Chile, and a surface high over northern Argentina. The synoptic forcing of the low is related to weak frontal disturbances that travel equatorwards. They result in a thickening of the marine layer that becomes blocked by the coastal escarpment, at the time of the onset of the ridge aloft. The blocking of the stable air above the subsidence inversion by the Andes is also hypothesized. The analysis of the subsidence inversion, the geometry of the coastal and Andes mountain ranges, and a scale analysis of the non-dimensional governing equations for the generation of the coastal lows, following the approach of Reason and Steyn (1990); leads to the conclusion that both blocking actions are strong and persistent in central Chile. An interactive mechanism between the upper and lower blocking effects is postulated to explain the cyclonic vorticity and the initial steering of the coastal lows. The scale analysis of the governing equations for the propagation stage of the low suggests that, departing for the South African case, non-linearity is important here, and that solitary Kelvin waves could be expected. Theoretical phase propagation speeds and Rossby radii are found to range between 8 and 15 m s-1 and 100-250 km, respectively. The importance of strong southerly winds ahead of the low and weak winds at its trailing edge is also stressed, as another major departure from the coastal-low behaviour elsewhere.

    Full Text Available Geopolitics, from concept named in 1917 by Rudolf Kjellén has been in continuous evolution until today. Since the incorporation of the representations, the first concept has been of vital importance in different territorial conflicts’ analysis. By means of a geopolitical analysis, the present article intends to understand the geopolitical representations in the area of southern ice fields, the last boundaries issue that still remains in abeyance between Chile and Argentina and how is that both countries have discussed the problem on a basis of representations, in which maps have been the image of each one facing the other, favoring in this way competition between states.

  19. The Incidence of Payroll Taxation: Evidence from Chile

    OpenAIRE

    1995-01-01

    Despite the growing reliance on payroll taxation worldwide, there is limited evidence on the incidence of payroll taxes. I provide new evidence by examining the experience of Chile before and after the privatization of its Social Security system. This policy change led to a sharp exogenous reduction in the payroll tax burden on Chilean firms; the average payroll tax rate in my sample fell from 30% to 5% over this six year period. I use data from a census of manufacturing firms, which contains...

    This study aims to characterize salmonid manures and to determine their potential use in agricultural soils. Sampling was carried out below salmon and trout cages in farms located in lakes and in the sea in the South of Chile during 2002-2003. Manure was analyzed for macronutrients, micronutrients and heavy metals. Results showed a high variability between samples and differences between sea and lake manure. Dry matter contents were low averaging c. 12-15%. Manures showed low OM contents with values heavy metal contents and a potential use in agricultural soils, which could reduce the risks of water pollution on water from fish farming. PMID:16962324

    Full Text Available This article analizes the installation in Chile of a neoliberal model during the military regime headed by General Augusto Pinochet, between 1973 and 1979. Within that context, it offers a reinterpretation of the allegedly foundational character of that government, its also supposedly early adherence to the neoliberal matrix, and its break with the Keynesian capitalism which had prevailed since the 1930’s. The analysis is focused on the evolution of military with regard to the links between the State and development, and on the debate between neoliberalism and statism that was carried out within the armed forces

  2. Chanco formation, a potential Cretaceous reservoir, central Chile

    Energy Technology Data Exchange (ETDEWEB)

    1983-07-01

    The Chanco embayment lies 300 km SSW of Santiago, Chile. The sequence within this basin above the metamorphic basement is: Chanco Formation (very clean sandstone), Quiriquina Formation (glauconitic sandstone, rich in organic matter), and Navidad Group (a very good caprock). This section thus contains reservoir, source and caprocks, and is therefore very promising for petroleum investigations. The offshore C-1 well yielded salt-water with gas shows, and two wells drilled onshore yielded shows of gas. The C-1 well lies on a gently-dipping EW-striking anticlinal structure, the presence of which makes the area very prospective.

    In order to understand the health system reforms, factors inherent to the health sector as well as external factors that gave origin to them must be considered. The policy of the World Bank acted as a determining factor and was taken into practice in the middle of processes that increased the inequalities in Latin America. The models of Chile and Colombia are examined from this background and some of the lessons that can be drawn from these experiences for other countries are pointed out.

  12. Fruit production in Chile: bright past, uncertain future

    Full Text Available In 2007 (the last agricultural census, Chile had 308, 445 ha of fruit orchards: an increase of almost 32% from the previous census (1997. The most important species were table grapes (20%, avocados (13% and apples (12%. Some 22% of the fruit crops growing area corresponded to juvenile orchards; within the species with higher proportion of juvenile orchards were prunes (42% and blueberries (56%. Most orchards are located between latitude 27º18` S (Copiapó and 40º36´S (Puerto Varas. The industry is driven by the export component which accounts for more than 50% of the fruits produced. In the crop season 2009-2010, approximately 254 million boxes (around 2.5 million tons were exported, representing over US$ 3.5 million. Processed and fresh fruits represented 8.2 and 26.7% of the total forest and agricultural Chilean exports in 2008, respectively. The main markets for this fruits were USA/Canada (42% and Europe (32%. The fruit grower receives, on average, 12-16% of the total price of the fruit in its final destination. Each year the fruit industry employs 450.000 people directly, of which 1/3 are permanent. Even though the fruit industry employs the highest proportion of the agricultural labor and the growing area has increased in the last 20 years, the proportion of agricultural employment has decreased from 19.5% in 1989 to 10.8% in 2008. It might also be noted that Chile invests only 0.7% of the GDP in research. In the last 40 years, the fruit industry has been a motor for the Chilean economic development, but the lower rates of currency exchange, the rising costs of energy (oil, electricity, and the increasing scarcity of hand labor have drastically reduced the profitability and are putting at risk the viability of a large proportion of the fruit orchards in Chile. It is estimated that this season around 65% of the orchards will have a negative economic balance in their operations. Higher investment in research, improvements in fruit quality

    2016-01-01

    Full Text Available Introduction: While a nationwide poison control registry exists in Chile, reporting to the center is sporadic and happens at the discretion of the treating physician or by patients’ self-report. Moreover, individual hospitals do not monitor accidental or intentional poisoning in a systematic manner. The goal of this study was to identify all cases of intentional medication overdose (MO that occurred over two years at a large public hospital in Santiago, Chile, and examine its epidemiologic profile. Methods: This study is a retrospective, explicit chart review conducted at Hospital Sótero del Rio from July 2008 until June 2010. We included all cases of identified intentional MO. Alcohol and recreational drugs were included only when they were ingested with other medications. Results: We identified 1,557 cases of intentional MO and analyzed a total of 1,197 cases, corresponding to 0.51% of all emergency department (ED presentations between July 2008 and June 2010. The median patient age was 25 years. The majority was female (67.6%. Two peaks were identified, corresponding to the spring of each year sampled. The rate of hospital admission was 22.2%. Benzodiazepines, selective serotonin reuptake inhibitors, and tricyclic antidepressants (TCA were the causative agents most commonly found, comprising 1,044 (87.2% of all analyzed cases. Acetaminophen was involved in 81 (6.8% cases. More than one active substance was involved in 35% of cases. In 7.3% there was ethanol co-ingestion and in 1.0% co-ingestion of some other recreational drug (primarily cocaine. Of 1,557 cases, six (0.39% patients died. TCA were involved in two of these deaths. Conclusion: Similar to other developed and developing nations, intentional MO accounts for a significant number of ED presentations in Chile. Chile is unique in the region, however, in that its spectrum of intentional overdoses includes an excess burden of tricyclic antidepressant and benzodiazepine overdoses, a

Un total de 7 especies pertenecientes a 6 géneros fueron identificadas: Pomacea bridgesii; Helobia sp.; Thiara (Melanoides tuberculata; Melanoides maculata; Physa sp.; Physella venustula y Biomphalaria sp. Melanoides maculata fue recolectada en el río Lluta y clasificada como especie criptogénica. Los moluscos exóticos recolectados podrían tener éxito en su establecimiento si se considera la vulnerabilidad de los hábitats nativos debido al cambio en las condiciones climáticas globales o a las elevaciones térmicas producidas en el sector costero por los fenómenos de El Niño. En este sentido, las especies subtropicales observadas se podrían considerar como no endémicas y vectores potenciales de zoonosis parasitarias. Las principales vías de introducción de moluscos dulceacuícolas exóticos se derivaron del intercambio comercial, por lo cual, y frente a su incremento interregional, se hace necesario recopilar datos ecológicos y taxonómicos adecuados que permitan evaluar el riesgo de su establecimiento, así como servir de base para la aplicación de futuros tratamientos en bioseguridad.The exotic freshwater mollusk species we report here were collected in wetlands, commercial aquariums, or were given to us by government officials who intercepted some exotic species at customs offices.

    The stochastic Truncated Lévy Flight model and detrended fluctuation analysis (DFA) are used to investigate the temporal distribution of earthquake magnitudes in Chile. We show that Lévy Flight is appropriated for modeling the time series of the magnitudes of the earthquakes. Furthermore, DFA shows that these events present memory effects, suggesting that the magnitude of impeding earthquakes depends on the magnitude of previous earthquakes. Based on this dependency, we use a non-linear regression to estimate the magnitude of the 2015, M8.3 Illapel earthquake based on the magnitudes of the previous events.

    Palaeoindian occupation of the Atacama Desert in northern Chile has been found between 12 600 and 10 200 cal. yr BP. The new site at Salar Punta Negra (24°28S/60°53W/2976 m) includes about 1000 classifiable, mostly unifacial artefacts and, uniquely, three different diagnostic types of early projectile points. Two of the Lateglacial/early Holocene projectile types have wide distribution and are known from different geographical areas in South America: the Palaeoindian Fell fish-tail point mainly from the southern cone of South America, and the triangular Tuina points typical of the Puna of the south-central Andes in northern Chile and northwestern Argentina. In addition, we found a third type, a stemmed point typical for the Salar Punta Negra. Filling a large geographical gap of Fell occupation, the site at Salar Punta Negra provides evidence for generally much higher mobility and diversity of early cultures, and supports an Andean-Pacific route for early human exploration of South America to the south through the desert at intermediate altitudes. Contemporaneous high-amplitude climatic changes were fundamental preconditions to provide adequate environments and habitats, and to make Palaeoindian hunting-gathering occupation possible in the Atacama Desert.

    A 3 a data set of isotopes in precipitation from northern Chile show a very distinct pattern, with {delta}{sup 18}O values ranging between -18 and -15per thousand at high altitude stations, compared to {delta}{sup 18}O values between -10 and -6per thousand at the lower altitude areas. The {sup 18}O-depleted values observed in the high altitude area, the Altiplano, are related to processes that affect the air masses that originated over the Atlantic, cross the Amazon Basin (continental effect), ascend the Andes (altitude effect) and precipitated (convective effect) in the Altiplano. It is postulated that a second source of moisture, associated with air masses from the Pacific, may contribute to the {sup 18}O-enriched values observed in the lower altitude areas. Similar isotopic patterns are documented in springs and groundwater indicating that the data presented in this paper are an accurate representation of the long term behavior isotopic composition of rain in northern Chile.

    During the first semester of 2009 Revista Médica de Chile has received an increasing number of manuscripts. Close to 30% were rejected while most other are in the process of being improved by the authors after receiving criticisms by external peer reviewers and the editors. The time lag between acceptance and publication of manuscripts is on an average six months. During 2008, 10% of articles published were submitted by authors from countries other than Chile and most of them were printed in English. Impact factor and other indexes provided by the ISI Web of Knowledge showed a promising improvement in 2008. The International Advisory Committee and the National Editorial Committee were renewed, a new Section on Laboratory Medicine was incorporated and several minor changes were done in design and format, in the title page and the issues' content. The main problems to be faced relate to the increasing cost of editing and printing, with a reduction in commercial advertising historically contributed by the pharmaceutical industry. Another major concern is to stimulate governmental agencies, scientific societies and universities to establish a national independent registry of clinical trials, that should become a mandatory requisite for every manuscript submitted to Chilean medical journals, reporting clinical trials performed in the country; foreign manuscripts should document the satisfaction of an identical requisite in their original source.

    In Chile, one of the developing countries in Latin-America, there are large social differences that persist between the richest and the poorest citizens. On the other hand, Chile has the advantage of a special and unique resource, the incomparably clear and dry skies in the desert of Atacama in the north of the country. This advantage is being exploited by the installation of large and powerful international observatories. However, the Chilean people's perception of this resource and the corresponding advantages for their country are still underdeveloped and rather poor. Therefore, we have been conducting successful outreach activities at all levels during the past few years, with special highlights during the International Year of Astronomy 2009, including participation of our undergraduate physics and astronomy students, the local media like newspapers, radio, and TV stations, talks and workshops in schools, popular talks for the general public, exhibitions, contests, and other multi-media efforts. We briefly describe these activities and outline the difference between our situation and that existing in developed countries like the USA.

  8. Abortion in Chile: the practice under a restrictive regime.

    This article examines, from a human rights perspective, the experience of women, and the practices of health care providers regarding abortion in Chile. Most abortions, as high as 100,000 a year, are obtained surreptitiously and clandestinely, and income and connections play a key role. The illegality of abortion correlates strongly with vulnerability, feelings of guilt and loneliness, fear of prosecution, physical and psychological harm, and social ostracism. Moreover, the absolute legal ban on abortion has a chilling effect on health care providers and endangers women's lives and health. Although misoprostol use has significantly helped to prevent greater harm and enhance women's agency, a ban on sales created a black market. Against this backdrop, feminists have taken action in aid of women. For instance, a feminist collective opened a telephone hotline, Linea Aborto Libre (Free Abortion Line), which has been crucial in informing women of the correct and safe use of misoprostol. Chile is at a crossroads. For the first time in 24 years, abortion law reform seems plausible, at least when the woman's life or health is at risk and in cases of rape and fetal anomalies incompatible with life. The political scenario is unfolding as we write. Congressional approval does not mean automatic enactment of a new law; a constitutional challenge is highly likely and will have to be overcome.

    The consequences of global warming on the Peru-Chile Current System (PCCS) ocean circulation are examined with a high-resolution, eddy-resolving regional oceanic model. We performed a dynamical downscaling of climate scenarios from the IPSL-CM4 Coupled General Circulation Model (CGCM), corresponding to various levels of CO2 concentrations in the atmosphere. High-resolution atmospheric forcing for the regional ocean model are obtained from the IPSL atmospheric model run on a stretched grid with increased horizontal resolution in the PCCS region. When comparing future scenarios to preindustrial (PI) conditions, the circulation along the Peru and Chile coasts is strongly modified by changes in surface winds and increased stratification caused by the regional warming. While the coastal poleward undercurrent is intensified, the surface equatorial coastal jet shoals and the nearshore mesoscale activity are reinforced. Reduction in alongshore wind stress and nearshore wind stress curl drive a year-round reduction in upwelling intensity off Peru. Modifications in geostrophic circulation mitigate this upwelling decrease in late austral summer. The depth of the upwelling source waters becomes shallower in warmer conditions, which may have a major impact on the system's biological productivity.

    Full Text Available The Peru Chile Current ecosystem is characterized by high biological productivity and important fisheries. Although this system is likely to be severely affected by climate change, its response to current global warming is still uncertain. In this paper we analyze 10–166 year old sediments in two cores collected in Mejillones Bay, an anoxic sedimentary setting favorable for preservation of proxies. Based on a 166 year chronology we used indicators of bottom water oxygenation proxies (Mo, V, S, and the (lycopane+n-C35/n-C31 ratio and surface water productivity (biogenic opal, counts of diatom valves, biogenic Ba, organic carbon and chlorins to reconstruct environmental variations in Mejillones Bay. We find that at decadal scales, and during the last two centuries, a shift in the coastal marine ecosystem off Northern Chile took place which was characterized by intense ENSO-like activity and large fluctuations in biological export productivity, in bottom water oxygenation, and increased eolic activity (inferred from Ti/Al and Zr/Al. On top of this short-term variability, a gradual increase of sulfidic conditions has occurred being even more intensified since the early 1960s.

    The third version of the World Kidney Day will be held on May 13, 2010 in Chile and will be focused in diabetic renal damage, the main cause of chronic kidney disease (CKD). Currently, we are living a pandemic of CKD, a progressive and irreversible condition with high social and economic impact. In Chile, we have 857 patients per million inhabitants in hemodialysis and 35% are secondary to diabetes. Our general prevalence of diabetes is 4.2%, rising to 15% in people aged more than 64 years. With a 34% prevalence of hypertension, an aging population, high prevalence of obesity, and a sedentary lifestyle, there is an estimation of a rise in 85% of the prevalence of diabetes in South-America, for the next decades. The steps to be taken are clear: campaigns should be aimed at (1) prevention of type 2 diabetes; (2) screening for early diabetic kidney disease; (3) increasing patient awareness of kidney disease; (4) using medications of proven strategy and finally (5) research on new therapies. These concepts must be included in community and professional education to reduce the effects of this pandemic. PMID:20668785

    In spite of the high prevalence of mental health disorders in Chile, there is a significant financing deficit in this area when compared to the world's average. The financing for mental health has not increased in accordance with the objectives proposed in the 2000 Chilean National Mental Health and Psychiatry Plan, and only three of the six mental health priorities proposed by this plan have secure financial coverage. The National Health Strategy for the Fulfilment of Health Objectives for the decade 2011-2020 acknowledges that mental disorders worsen the quality of life, increase the risk of physical illness, and have a substantial economic cost for the country. Thus, this article focuses on the importance of investing in mental health, the cost of not doing so, and the need for local mental health research. The article discusses how the United States is trying to eliminate the financial discrimination suffered by patients with mental health disorders, and concludes with public policy recommendations for Chile.

    Full Text Available Between 1975 and 2000, annual per-capita GDP in Chile grew at 5%. Yet, regions did not benefit equally: poverty declined significantly in all regions but regional income inequality remained stagnant. We found that convergence in per-capita income and productivity levels is too slow to become a significant force in equalizing regional income. Lack of convergence is mostly associated with low levels of internal migration. This, in turn, is found to be largely the result of government policies, in particular, public housing. The efficient targeting of subsidies coupled with the prohibition to sell houses, tied families to their geographical location, inhibiting migrationEntre 1975 y 2000, el PIB por habitante creció 5% por año en Chile. Sin embargo, las regiones no se beneficiaron de igual forma: la pobreza cayó significativamente en todas ellas, pero la desigualdad de ingreso regional se mantuvo constante. Encontramos que la convergencia en el ingreso y productividad per capita es demasiado lenta para igualar los ingresos regionales. La falta de convergencia se relaciona con la insuficiente migración interna. Esta se debe, en gran medida, a políticas públicas, en especial la de vivienda. La alta eficiencia en la asignación de subsidios en conjunto con las restricciones de enajenación han anclado a las familias a sus lugares de origen, inhibiendo la migración

    Temperament refers to individual differences in reactivity and self-regulation and is influenced by genetic and experiential variation and maturation. Temperament reflects biologically based individual differences that emerge in early life and remain relatively stable thereafter. Given the growing interest in cultural variation in infant temperament, this study examined the temperament of 12-month-old children in Chile and the US. The aims were to validate a version of the Infant Behavior Questionnaire - Revised - Very Short Form in Spanish for Chile and to compare Chilean and US infants' temperament. For the first aim, 150 Chilean infants aged 10-15 months were assessed, and 73 US infants aged 10-15 months were examined for the second aim. The children's parents completed a demographic questionnaire and the IBQ-R-VSF, which measures three dimensions of temperament: Surgency, Negative Affectivity, and Effortful Control. The reliability of each dimension for the Chilean sample was between 0.70 and 0.75, and significant differences between Chilean and US infants emerged. Parents of Chilean infants reported higher levels of Effortful Control, whereas US parents reported that their infants exhibited higher levels of Negative Affectivity. A relationship between parents' higher educational level and infants' higher levels of Surgency was found for both countries. No gender or age differences were observed for any of the three temperament dimensions. These results and their implications for cultural studies are discussed. PMID:27450101

    Different Seed Selection and Conservation Practices for Fresh Market and Dried Chile Farmers in Aguascalientes, Mexico. The process of selecting and saving seed is the most basic and oldest of agricultural practices. In today's modern and highly capital-intensive agriculture, seeds are often treated like another chemical input. This study sought to examine seed selection and saving practices among chile farmers in Aguascalientes, Mexico, where both industrial and traditional agriculture are practiced. We observed a clear division among farmers who plant chile peppers commercially. Sixty-eight chile pepper farmers were surveyed in order to document seed selection and saving practices. Fifteen respondents (22%) planted chile peppers destined for the fresh market and all utilized purchased commercial seed of F1 hybrid varieties. Fifty-three farmers (78%) planted chiles to be dried and either saved their own or purchased seeds that others had saved and selected. Farmers who saved their own seed sought to maintain an ideotype, rather than directionally select for certain traits, much like Cleveland et al. (2000) chronicled in central Mexican maize farmers. Farmers would benefit from a participatory plant-breeding program in order to maintain productive seed stock for the continued cultivation of dried chile pepper in the state. PMID:21212817

This result is not valid for the asymmetric Box-Cox non linear model. Furthermore, we found that high levels of uncertainty in inflation increase the level of inflation with some lags, not rejecting the positive correlation established by Cukierman and Metzler.

    This thesis attempts to explain how advanced economies with large mining sectors, like those of Australia and Chile, have managed to avoid the resource curse. Minerals (iron ore and coal) account for over two-thirds of Australia’s exports, and minerals (copper) amount to over two-thirds of Chilean exports as well. Hence, Australia and Chile have been labeled as commodity-based economies in the past. There is some validity to this claim, as Chile has gained significant fiscal revenues from cop...

    Full Text Available Resumen Al igual que el resto de las ciencias sociales, la ciencia política chilena está en deuda con su historia. Si bien existen reflexiones puntuales, más bien descriptivas, sobre la disciplina, no se ha desarrollado un análisis auto-reflexivo sobre su devenir como disciplina y profesión. A pesar de su relativa juventud, es ésta una tarea pendiente que, de enfrentarse, puede contribuir a hacer sentido acerca de su rol y naturaleza. A partir de la utilización del enfoque internalista, se recurre a la aplicación de entrevistas a cientistas políticos a fin de auscultar la percepción y las imágenes que los propios cultores tienen de temas relacionados con la vocación, la concepción de lo político y los ideales explicativos de la disciplina, los referentes disciplinarios, su función y relevancia social, sus fortalezas y posibilidades. Se propone, entonces, un primer relato que contribuya a una mayor sensibilización acerca del pasado y del futuro de la disciplina.Abstract Political science, like the other social sciences in Chile, is in debt with its history. While there have been some specific and descriptive reflections, an analytical reflection about its development as a discipline and profession is necessary. Despite the relative youth of political science in Chile, such a task can help us make sense its role and nature. Using an internalist approach and interviews with Chilean political scientists, the article examines perceptions and images about issues related to political science as a vocation, how the study of politics has been conceptualized historically, its references, its function and social relevance, its strengths and possibilities. The result is an account which may serve as a first step towards the creation of an increased sensibility for the past and the future of the discipline in Chile.

    Full Text Available A section equivalent to the Pliocene La Portada Formation exposed in the coastal cliff at Hornitos, northern Chile, contains a ca. 7-10 m thick conglomerate bed. The bed occurs within a succession of shallow marine sandstones and has an erosional contact with underlying strata. The largest boulders of basement (5 m are angular to very angular and are set within a matrix of very poorly sorted fine to very coarse grained shell-rich sandstone. Also present are very well rounded granodiorite pebbles and shallow marine sandstone intraclasts (maximum 10 m. The clast size, erosional contact, associated facies and bed thickness suggests that the conglomerate bed is a shallow marine tsunami deposit. The angular clasts indicate limited transport and no marine reworking prior to deposition. They represent alluvial fan sediment incorporated into the bed during tsunami backflow. Intraclasts of shallow marine sandstone are thought to have been ripped up and included in the bed during the seaward passage of the tsunami across the shorefaceUn posible depósito de tsunami Plio-Pleistoceno, Hornitos, norte de Chile.

  7. Coastal Upwelling off Chile: Ocean Productivity and Surface Sediments

    2002-12-01

    The coastal upwelling system of the Peru-Chile Current belongs to the most productive regions in the world oceans. In spite of this fact only very little is known about the sediment distribution in its southern part off the coast of Chile. To increase the knowledge about this region a multi-parameter study of the surface sediment distribution at over 100 sampling sites along the Chilean continental slope between 23°S and 45°S has been carried out. Detailed analyses of sedimentary data (TOC, carbonate, and biogenic opal contents, delta 15N) reveal a close relation to environmental conditions in the region. Coastal upwelling along the Chilean coast, centered around main upwelling centers such as off Antofagasta (23°S), off Lengua de Vaca (30°S), off Valparaiso (33°S), and off Concepci¢n (35-38°S), sustains the high productivity observed in satellite pigment data and in sediment data. However, the highest pigment concentrations are found south of 40°S where prevailing onshore winds of the Southern Westerlies generally prevent coastal upwelling. There, also highest estimated accumulation rates of organic carbon and biogenic opal at the sea floor are found. Thus, the general pattern of a southward increase of surface water productivity known from satellite data is closely reflected in the organic carbon, biogenic opal and ?15N data, although the observation of highest productivity south of the upwelling area is surprising. Probably, this high productivity in the south can be attributed to the advection of (macro-) nutrients by the Antarctic Circumpolar Current, supplying so-called high nutrient-low chlorophyll (HNLC) waters to the Chilean margin. Impinging on the Chilean margin these waters can take up micronutrients such as iron from the strong riverine input and from benthic exchange processes. The combination of macro- and micro-nutrients in this area most likely results in the high productivity of the area between 40°S and 45°S. From there these fertile

    Drought and water scarcity are important hazards and can lead to severe socio-economic impacts in many regions of the world. Given the interlinked interactions and feedbacks of hydrological droughts and their impacts and management, we need tools to evaluate these complexities and effects on the availability of water resources. Here we use a real-world case study of the Huasco basin (Northern Chile) in which we quantify the influence of human activities on hydrological drought signals. In this arid region, Andean snowmelt provides water essential for users, with agriculture acting as the main water consumer (85% of total). An increasing water demand from different water sectors (agriculture, mining, and domestic water usage) has increased pressure on available water and its management. Consequently, the Santa Juana dam was built by 1995 to increase irrigation security for downstream users, and recent management and restrictions have been established with the objective to limit impacts of hydrological droughts across the basin. The feedbacks between water availability and water management are explored for this water stressed region in Chile. Hydro-meteorological (e.g. precipitation, temperature, streamflow, reservoir levels) variables have been analysed to assess trends and drought patterns. Data over the past three decades has indicated a decrease in surface water supply, with the basin entering a situation of water scarcity during the recent multiyear drought (2007 - to-date), partly caused by meteorological drought and partly by abstraction. During this period, water supply failed to meet the demands of water users, resulting in the implementation of water restrictions. As well as the necessary continuous hydro-meteorological data, here we used information on human water users and scenario modeling, allowing for the analysis and quantification of feedbacks. This work highlights the importance of local knowledge, especially in understanding water laws, rights

    Full Text Available Este trabajo muestra que la participación electoral en Chile hoy no es menor a la observada hasta antes de 1973. La alta tasa de participación en 1988 representa una comprensible anomalía. Después de 15 años sin votar, los chilenos participaron entusiastamente en el plebiscito. Pero a partir de entonces, la tasa de participación tendió a la baja hasta llegar a fines de los 90 a niveles similares a los observados antes del quiebre democrático de 1973. Usando un marco teórico que aborda la participación como una función basada en costos y beneficios, discute la participación electoral en Chile en un contexto internacional, subrayando las diferencias y similitudes de los patrones existentes antes de 1973 y después de 1988, enfatizando tanto lógicas de inscripción como de participación electoral. Al hacerlo, aborda la tensión que existe entre un electorado estable y un número creciente de personas no inscritas para votar. Por último, identifica algunas propuestas que permitirían eliminar las trabas institucionales que han llevado a la formación de dos clases de adultos, aquellos que estando inscritos están obligados a votar y los que al no estar inscritos no pueden sufragar. Puntualmente, argumenta que al automatizar la inscripción se puede incorporar a todos sin tener siquiera que entrar a discutir la obligatoriedad del votoContrary to a widespread belief, post-1990 electoral participation in Chile is not lower than before 1973. The high turnout rates observed in 1988 constitute an understandable anomaly. After 15 years without elections, Chileans enthusiastically participated in the plebiscite. Yet, after that event, turnout rates fell during the 1990s to levels similar to those observed before 1973. Using a theoretical framework that defines turnout as a function based on cost and benefits, I discuss electoral participation in Chile in an international context, highlighting the differences and similarities between the

  11. Site testing for the VLT in Northern Chile

    Science.gov (United States)

    Woltjer, L.

    The European Southern Observatory (ESO) will need sites for three telescopes. The telescopes considered include the 3.5 m New Technology Telescope to be completed in 1987, the 15 m Swedish-ESO mm/submm telescope, and the Very Large Telescope (VLT). The first two telescopes will probably be placed on La Silla. However, because of humidity considerations, a later transfer of the 15 m mm/submm telescope to a drier site appears possible. The main reason for conducting a new site survey is related to the VLT. Possible areas for establishing an observatory in the Southern Hemisphere are examined, taking into account Northern Chile. Attention is given to an area south of Antofagasta, mountains west of the Salar de Punta Negra, mountains between San Pedro de Atacama and El Tatio, mountains east of La Silla, problems regarding the observation of faint objects, water vapor content, and difficulties due to wind.

  12. Studies on osteoporosis in Chile using isotope-related techniques

    International Nuclear Information System (INIS)

    Several studies on bone densitometry measurements in healthy individuals have been performed in Chile. However due to the fact that different techniques and no uniform protocols have been used to select patients, the results obtained are not suitable as reference values for a normal chilean population. Therefore, foreign reference values are used. This study will select healthy normal individuals, typical urban chilean residents, and measure bone density using the DEXA technique. The selection will be made according to a well defined protocol. Serum osteocalcin, a marker of bone remodeling, will be measured in all subjects as a means-a assessing bone metabolism. Bone trace element composition will be measured in selected subjects. Samples will be obtained by biopsy or through normal surgical procedures and will be analyzed by neutron activation analysis.

    The lithosphere activity during seismogenic or occurrence of one earthquake may emit electromagnetic wave which propagate to ionosphere and radiation belt, then induce disturbance of electric and magnetic field and the precipitation of high energy charged particles. This paper, based on the data detected by DEMETER satellite, present the high energy charged particle burst(PB) with 4 to 6 times enhancement over the average value observed about ten days days before Chile earthquake. The obvious particle burst was also observed in the northern hemisphere mirror points conjugate of epicenter and no PB events in different years over the same epicenter region was found. The energy spectra of the PBs are different from the one averaged within the first three months in 2010. At the same time, the disturbance of the VLF electric spectrum in ionosphere over the epicenter detected by the DEMETER satellite are also observed in the same two orbits. Those observations from energetic PB and VLF electric spectrum disturbance...

    2016-01-01

    The worldwide scarcity of cadaveric organs for transplants is on the rise, due in part to extended medical indications and longevity of chronic patients with organic insufficiencies. Chile has an extremely low donor rate of 6.7 per million. Although consent is presumed by law, and recently amended to include a “reciprocity principle”, nearly four million persons have expressed in writing their unwillingness to donate and, of those remaining, 53% of families have rejected donating the organs of their deceased. New proposals are urgently needed, even if some of them have previously been rejected: nonmaterial incentives, partial donations and unveiling anonymity to enhance personal ties between donors and recipients. Transparency, information and assistance are to be reinforced in order to regain trust in transplant procedures. PMID:27570970

  17. Soil erosion and its control in Chile - An overview

    International Nuclear Information System (INIS)

    Accelerate erosion in Chile is a consequence from land use that degrade soil such as compaction, loss of organic matter and soil structure. The erosion is favored by the very hilly landscape of the country that increases erosivity index and the high erodibility given by an elevated annual rate of rainfall with irregular distribution. Several experiences have demonstrated that adequate crop management and crop rotations can minimize erosion. The most effective control is achieved conserving and improving soil structure with management systems that include regular use of soil-improving crops, return of crop residues and tillage practices, thus avoiding unnecessary breakdown soil or compacted soil structure. Conservation tillage increased organic matter levels improving stabile soil structure, aeration and infiltration. (author)

Se plantea que las identidades que alli se construyen son expresión de los procesos de segregación urbana de la ciudad de Santiago y ellas dan cuenta del debilitamiento de un modelo urbano asentado en la heterogeneidad social, la noción de espacio público y valores como la ciudadanía política y la integración social. Paradojalmente, esta misma segregación urbana abre también paso a un imaginario y una práctica de vida comunitaria y tribal que refuerza y protege al nosotros de la peligrosidad de los otros.

  19. [Community participation in health: the challenge in Chile].

    Science.gov (United States)

    Méndez, Claudio A; López, Jairo J Vanegas

    2010-02-01

    Health care reforms implemented in Latin America and the Caribbean over the last 20 years have viewed community participation as a system-wide component. Nonetheless, these reform efforts have yet to break through the conceptual and operational barriers holding back the development and expansion of community participation. In Chile, changes introduced to the health care system are far from achieving any real participation from the community. Therefore, the consumer's role needs to be redefined from merely controlling the parts, to reaching across the whole system in a way that consumer input might identify and quickly correct any possible shortcomings in the health system's design, as well as its operations. With this in mind, the main challenges are to strengthen coordination among the various promotion and participation commitments, as well as community control, and to generate data and other evidence to assess the impact of community participation in health strategies.

  6. Strontium isotope data for recent andesites in Ecuador and North Chile

    International Nuclear Information System (INIS)

    New Sr isotope data are presented for andesite lavas from active volcanoes in Ecuador and North Chile. Twenty-three samples from five Ecuadorian volcanoes have 87Sr/86Sr ratios most of which are essentially within analytical error, and average 0.7044. In contrast, 16 samples from the San Pedro-San Pablo volcano complex in North Chile have 87Sr/86Sr ratios between 0.7058 and 0.7072. These samples show no correlation between 87Sr/86Sr and 87Rb/86Sr, nor between 87Sr/86Sr and other elements or ratios. The major difference in setting between the two volcanic provinces lies in the thickness of the continental crust; 40-50 km beneath Ecuador, 70 km beneath North Chile. Andesites from both areas are derived primarily from the mantle, but those from North Chile show evidence of a significant Sr isotopic contribution from the continental crust. (Auth.)

    Full Text Available This article explores the relationships between memory politics and urban heritage in the construction of a twenty-first century democratic society. It focuses on the case of Chile and concentrates on three examples of public buildings in the capital city, Santiago. Given what can be considered a difficult heritage –linked to the recent experience of dictatorship and state sponsored violence– these buildings have been in recent years objects of heritage politics, directed to address a public memory related to those events. Based on these case studies, the article critically discusses the materialization of the dominant human rights discourse in the current memory politics affecting Santiago’s urban heritage.Este artículo aborda las relaciones entre políticas de memoria y patrimonio urbano en el proceso de construcción de una sociedad democrática del siglo XXI.

    During the year 2012, 539 manuscripts were submitted to this journal, following an increasing trend in the recent decade. Rejection rate was 33%. This higher number of submissions demanded a larger number and wider scope of external reviews, retarding the editorial process. The mean time lapse from reception to acceptance (or rejection) was 6.3 months (range 2-14) and from acceptance to publication 5.3 months (range 3-7). Research articles were 43.9% of published manuscripts and the remaining articles were Reviews, Special Articles, Case Reports, articles on Medical Ethics, Medical Education, Evidence Based Medicine, Public Health, History of Medicine, Letters to the Editor and others. Thirty seven published manuscripts (14.6%) came from foreign countries and 9 of them were published with full text in English. The 2012 Impact Factor was 0.360, showing little variation from previous years, locating the journal in the upper part of quartil 4 in the ISI-JCR category "Medicine, General and Internal", while the SCImago Journal & Country Rank locates the Revista in quartil 2 of its category "Medicine (miscellaneous)". In contrast with the low citation rate, the number of visits to the open access electronic version in www.scielo.cl averages over 3 million visits per year, illustrating that the interest among readers outnumbers the country's expectable readership.

    Full Text Available A food web model is constructed to describe predator-prey interactions, community structure and trophic flows in northern Chile upwelling ecosystem (18°20'S, 24°S, for the year 1997. The model is built using the Ecopath with Ecosim software version 6.4, and encompasses 21 functional groups, ranging from primary producers (phytoplankton to top predators (birds and marine mammals, the principal fishing resources and the fishery. Input parameters required to build the model were gathered from specialized literature, grey literature and our own estimates. The results indicated that the total biomass (B T was estimated at 624.7 ton km-2. The combined biomass of small pelagic fish represented 26% of B T, while the combined biomass of demersal fish represented only 0.1% of B T. These results highlight the importance of pelagic fish in this system. Predation mortality resulted to be the main source of mortality. Nevertheless, fishing mortality was important in anchovy, mackerel, common dolphinfish and jack mackerel. The mean trophic level of the fishery was estimated as 3.7, with landings sustained mainly by anchovy. Primary production required to sustain the landings (PPR was estimated at 7.5% of calculated total net primary production, which is lower than PPR estimates in other upwelling ecosystems. The average trophic transfer efficiency was 18%, which is in the range (10-20% informed for marine ecosystems. Results indicate that in 1997 the northern Chile marine ecosystem was characterized for being a system far from maturity, dominated in terms of biomass and flows by the pelagic realm.

    In this paper we compare the resource flows of Chile, Ecuador, Mexico and Peru between 1980 and 2000. In this time span, the domestic extraction of materials increased in the four countries, mainly due to the mining sector in Chile and Peru, biomass and oil in Ecuador and construction minerals in Mexico. Imports and exports increased too, due to the increasing integration in the international markets, prompted by the liberalization policies undertaken by the four countries between the late 19...

    Chile and Mexico experienced severe economic crises in the early 1980s. This paper analyzes four possible explanations for why Chile recovered much faster than did Mexico. Comparing data from the two countries allows us to rule out a monetarist explanation, an explanation based on falls in real wages and real exchange rates, and a debt overhang explanation. Using growth accounting, a calibrated growth model, and economic theory, we conclude that the crucial difference between the two countrie...

    Araya, Juan Francisco

    2015-01-01

    The bulimulid genus Bostryx Troschel, 1847 is the most species-rich genus of land snails found in Chile, with the majority of its species found only in the northern part of the country, usually in arid coastal zones. This genus has been sparsely studied in Chile and there is little information on their distribution, diversity or ecology. Here, for the first time, a formal analysis of the diversity of bulimulids in the Región de Atacama, northern Chile, is reported. Of the seventeen species recorded for the area, most of them were efectively found in the field collections and one record was based on literature. Five taxa are described as new: Bostryx ancavilorum sp. nov., Bostryx breurei sp. nov., Bostryx calderaensis sp. nov., Bostryx ireneae sp. nov. and Bostryx valdovinosi sp. nov., and the known geographic distribution of seven species is extended. Results reveal that the Región de Atacama is the richest region in terrestrial snails in Chile, after the Juan Fernández Archipelago. All of the terrestrial molluscan species occurring in the area are endemic to Chile, most of them with restricted geographic distributions along the coastal zones, and none of them are currently protected by law. Further sampling in northern Chile will probably reveal more snail species to be discovered and described. PMID:26587346

  12. Market Brief : The electric power equipment and services market in Chile

    International Nuclear Information System (INIS)

    This report presents some quick facts about the electric power equipment and services market in Chile and presents opportunities for trade. Chile, a net importer of energy, is seeking foreign participation in its electric power industry, with no restrictions on equipment imports. Chile currently imports most of its oil and gas from Argentina, but more than half of its electricity production is from hydro sources. Operators in the fully privatised electric power sector are separated into 31 power generation companies, 5 transmission companies and 36 power distributors. Chile has 5 gas pipelines, 1 oil pipeline and a power line. The key players and customers in the oil and gas sector were described along with an export check list. Power demand is expected to grow by about 5 per cent annually over the medium term. This will create a demand for more than 500 megawatts of new capacity each year. The greatest opportunity lies in the development of turbines, transformers, generators and switching gear. Competition is stiff as several top international manufacturers of electric power equipment are represented in Chile. Local manufacturers are mostly interested in power distribution equipment. Currently the major end-users are industrial users, particularly the mining industry. Imports from Canada are duty free and will be phased out under the Canada-Chile Free Trade Agreement. A list of key contacts and support services is included with this report. refs., tabs., figs

    Firewood in Latin America is, after petroleum, the second primary source of energy. In Chile, the statistics have shown that the total use of energy produce by firewood fluctuates between 16 and 21% from which the residential sector represents 54%. There are great social and environmental impacts produced by the use of firewood. For the near future, it will be difficult to eradicate the firewood consumption in Latin America. In looking for sustainable use of firewood to produce energy, NGOs have developed efficient systems for production, management and consume of it. For this research we will focus on the efficient use of biomass and solar energy use for cooking, both to be applied in suitable places. The paper shows Chilean experiences on both, biomass and solar energy production, and how these programs have impacted the national statistics in energy consumption. (Author)

    Full Text Available Introduction Waiting lists are a well-known problem in public healthcare systems worldwide. For instance, England had over one million people in waiting lists for elective surgical procedures in 2000. Spain had over 360 000 patients in surgical waiting lists in 2007. Chile has been trying to manage waiting times through the GES (Explicit Guarantees in Healthcare plan, which was established by the Chilean government in 2005. Waiting lists for the guaranteed-care diseases in the GES plan had 380 000 patients at the beginning of 2010, and that number was reduced to zero in 2011. Internationally, there are some descriptive studies about waiting lists that focus on variables such as waiting times and number of patients in the list. In Chile, however, this type of study is lacking. Purpose This study aims to describe the characteristics of waiting lists for medical specialties between April and October 2011. It also aims to identify the components of management models in public healthcare centers, and to identify and analyze waiting-time frames of patients referred to a secondary or tertiary healthcare public center from a public primary healthcare center. Methods A descriptive cross-sectional study of the waiting list for first-time consultations for medical specialties was carried out. Referred patients were described and grouped using indicators of access to healthcare and waiting time between April and October 2011. Each consultation request or referral of a new patient was included in the waiting list and analyzed. Results There were 15 935 requests for consultations; 5 717 requests were resolved, and 8 544 were not (54% of the total requests for consultation. There was a mean waiting time of 498 days for non-resolved requests for consultation, and a mean of 141 days for resolved requests. The specialties in highest demand were orthopedic surgery and ophthalmology. The main waiting-list management processes were referral and reception of requests

La presente experiencia tiene como objetivo establecer las relaciones biológicas de Caleta Huelén 42 con otros grupos arcaicos costeros. La colección está constituida por 33 individuos y los fechados conocidos la ubican entre el 4780 y el 3780 AP. Las afinidades biológicas con grupos semejantes (Morro 1, Morro 1/6, Morro Uhle, El Cerrito y Punta de Teatinos se analizan mediante el empleo de 29 caracteres métricos del cráneo y la aplicación de diferentes técnicas de análisis multivariado. Se demostró la existencia de dos conglomerados biológicos uno constituido por las muestras del Norte Árido (Morro Uhle, Morro 1, Morro1/6 y Caleta Huelén 42 y el otro por las series del Norte Semiárido (El Cerrito y Punta de Teatinos. Los fundadores de Caleta Huelén 42 son el resultado de la migración hacia el sur de una pequeña banda de cazadores recolectores arcaicos, que conservaron parte de genoma original y características culturales que los conecta con la tradición Chinchorro. Además, es posible que hayan recibido el aporte genético de grupos arcaicos proveniente del interior del continente a través del río Loa.

    On September 16th, 2015, an Mw 8.3 earthquake (USGS moment magnitude) ruptured offshore of central Chile, 50 km west of the city of Illapel and 200 km north of Santiago. The earthquake occurred just north of where the Juan Fernandez Ridge enters the subduction zone. In this study, we integrate multiple seismic and geodetic datasets, including multiple-event earthquake relocations; moment tensors of the Illapel mainshock, aftershocks, and prior regional seismicity; finite fault models (FFMs) of the mainshock rupture; subduction zone geometry; Coulomb stress transfer calculations; and co-seismic GPS offsets and InSAR images. These datasets allow us to (a) assess the context of the Illapel earthquake sequence with respect to historical seismicity in central Chile; (b) constrain the relationship between subduction geometry and the kinematic characteristics of the earthquake sequence; and (c) understand the distribution of aftershocks with respect to the rupture zone. Double source W-phase moment tensor analysis indicates the Illapel mainshock rupture began as a smaller Mw ~7.2 thrusting event before growing into a great-sized Mw 8.3 earthquake. Relocated aftershock seismicity is concentrated around the main region of slip, and few aftershocks occur on the megathrust shallower than ~15 km, despite the FFM indicating slip near the trench. This distribution is consistent with the aftershock behavior following the 2010 Maule and 2014 Iquique earthquakes: aftershocks primarily surround the rupture zones and are largely absent from regions of greatest slip. However, in contrast to the recent 2014 Iquique and 2010 Maule events, which ruptured in regions of the Chilean subduction zone that had not had large events in over a century, this earthquake occurred in a section of the subduction zone that hosted a large earthquake as recently as 1943, as well as earlier significant events in 1880 and 1822. At this section of the subduction zone, in addition to the impinging Juan

    2002-05-24

    The discovery of two high-temperature fumaroles, with gas geochemistry compatible with an economic geothermal system, established Apacheta as one of the most attractive geothermal exploration prospects in northern Chile. These remote fumaroles at 5,150 m elevation were first sampled in 1999 by ENAP and its partners, following up on the reports of a CODELCO water exploration well that flowed small amounts of dry steam at 4,540 m elevation in the valley 4.5 km east of the fumaroles. The prospect is associated with a Plio-Pleistocene volcanic complex located within a NW-trending graben along the axis of the high Andes. The regional water table is 4,200 masl. There are no hot springs, just the 88 degrees C steam well and the 109 degrees and 118 degrees C fumaroles with gas compositions that indicate reservoir temperatures of greater than or equal to 250 degrees C, using a variety of gas geothermometers. An MT-TDEM survey was completed in 2001-2002 by Geotermica del Norte (SDN), an ENAP-C ODELCO partnership, to explore the Apacheta geothermal concession. The survey results indicated that base of the low resistivity clay cap has a structural apex just west of the fumaroles, a pattern typically associated with shallow permeability within a high temperature geothermal resource. SGN plans to drill at least one exploration well in 2002-03 to characterize a possible economic resource at Apacheta.

    Aquatic and migratory birds, the main reservoir hosts of avian influenza viruses including those with high pathogenic potential, are the wildlife species with the highest risk for viral dissemination across countries and continents. In 2002, the Chilean poultry industry was affected with a highly pathogenic avian influenza strain, which created economic loss and triggered the establishment of a surveillance program in wild birds. This effort consisted of periodic samplings of sick or suspicious animals found along the coast and analyses with standardized techniques for detection of influenza A virus. The aim of this work is to report the detection of three avian influenza strains (H13N2, H5N9, H13N9) in gulls from Chile between 2007-2009, which nucleotide sequences showed highest similitudes to viruses detected in wild birds from North America. These results suggest a dissemination route for influenza viruses along the coasts of Americas. Migratory and synanthropic behaviors of birds included in this study support continued monitoring of avian influenza viruses isolated from wild birds in The Americas and the establishment of biosecurity practices in farms.

    Healthcare represents a key area in the public agenda. In the case of Chile, this central part of citizen demands has emerged with an increasing criticism of the health system, its actors and institutions, while a major democratic and legitimacy crisis in Chilean society unfolds. The starting point of this analysis is the link between the critical and widespread societal dissatisfaction with the legitimacy crisis in the health sector. There is an interdependence and parallelism between these two different aspects of the crisis. The analysis is built around the dimensions of trust and legitimacy as a potential driver of the conflict, taking as an analytical framework the socio-political matrix. Conceptual elements around the ideas of trust and legitimacy in public policies are reviewed. This article focuses on recent situations surrounding the dynamics of the Chilean health system such as the rise of the Instituciones de Salud Previsional (ISAPRE) and the market-driven health system, the failed health care reform of the last decade, conflicts of interest in the formulation of public policies, loss of legitimacy of healthcare authorities, and the role of the health professionals in this process. Finally, a discussion arises seeking to regain public trust as a central issue for the future development and sustainability of health policies. PMID:27602919

  16. Nitrogen fixation in four dryland tree species in central Chile

    International Nuclear Information System (INIS)

    Results are presented from a 5-year experiment using 15N-enriched fertilizer to determine N2 fixation in four tree species on degraded soils in a Mediterranean-climate region of central Chile in which there are 5 months of drought. Species tested included three slow-growing but long-lived savannah trees native to southers South America, (acacia caven, Prosopic alba and P. chilensis; Mimosoideae), and Tagasaste (Chamaecytisus proliferus ssp. palmensis; Papilonoideae), a fast-growing but medium-lived tree from the Canary Islands. Tagasaste produced four- to twenty-fold more biomass than the other species, but showed declining N2 fixation and biomass accumulation during the 5th year, corresponding to the juvenile-to-adult developmental transition. Nitrogen content was significantly higher in Tagasaste and Acacia caven than in the other species. The data revealed inter-specific differences in resource allocation and phenology of N2 fixation rarely detailed for woody plants in dryland regions. (author)

    Between 10,000 and 500 yr ago the Socompa volcano in northern Chile experienced a catastrophic collapse of a 70 deg sector of the original cone, causing a debris avalanche that descended nearly 3000 m vertically and traveled more than 35 km from the volcano. The deposits cover some 490 sq km and have a minimum volume of 15 cu km. Parts of the original cone slumped in a nearly coherent form and are now preserved as large blocks more than 400 m high. The primary avalanche traveled northwestward over sloping ground before coming to rest transiently, forming a prominent marginal ridge, and then slid away northeastward to form a secondary flow, overriding much of the primary avalanche deposit. Abundant, prismatic, jointed dacite blocks within the debris avalanche deposit and a thin, fine-grained pumiceous deposit beneath it suggest that the collapse was triggered by magmatic activity and may have been accompanied by a violent lateral blast. Collapse was followed by eruption of pumiceous pyroclastic flows and extrusion of voluminous dacite domes.

    Chile has a unique geography that provides an extraordinary variety of climatic conditions and availability of water resources. The objective of this manuscript was to describe and analyze the spatial and temporal distribution patterns, as well as the management of water resources, along a country with a narrow distance from the Andes Mountains to the Pacific Ocean. This presents challenges to water governance from data collection and analysis perspectives, and for administration of the resource. The Water Resources Directorate (Dirección General de Aguas, DGA), is the federal government organization in charge of the water resources of the country. The DGA and other relevant public and private institutions are examined in terms of competition and conflict resolution across different scales and levels of interaction associated with water resources governance. Both monitoring stations (rainfall, streamflow, water quality, groundwater, sediment and snowfall), and the Chilean management and legislation of water resources are also analyzed. Finally, the success (or lack) of the national administration to upgrade its monitoring stations and equalize water resources distribution throughout the country is discussed including the influence of climate change on data collection, and decision making across different scales of water governance.

  19. The distributional incidence of the gasoline tax in Chile

    International Nuclear Information System (INIS)

    This paper analyzes the distributional incidence of the excise tax on gasoline in Chile using Household Budget Surveys. The incidence is calculated with respect to both income and expenditure distributions in order to consider the potential differences between transitory and permanent income. The Suits Index is estimated as a measure of the degree of progressivity of the tax, and confidence intervals are calculated using a bootstrap methodology to statistically compare changes in the incidence given changes in the tax. The results show that the tax, contrary to the evidence for several developed countries, is slightly or moderately progressive, with a lower degree of progressivity observed in the calculations based on income than those based on expenditure. The simulation of the 25% reduction in the tax rate implemented in 2008 shows that, in terms of incidence, its effect is to reduce the progressivity of the gasoline tax, which is the opposite of what was sought by the government with this policy. -- Highlights: •Gasoline tax is an optimal tax and is a significant instrument of climate policy. •Despite its benefits, it faces political economy challenges in its implementation. •In the public discussion in developing countries the tax is considered regressive. •The estimation of the distributional incidence shows that it is slightly progressive. •Increases in gasoline taxes can reduce both negative externalities and inequality

La democracia chilena, analizada a través de las dimensiones constitucional, electoral y ciudadana, presenta la contradicción entre los grandes avances conseguidos bajo los gobiernos de la Concertación y las debilidades en las tres dimensiones. Estas debilidades se explican por los limites fundantes en la soberanía popular observados a partir de la Constitución, que consagró la exclusión política a través del sistema binominal, de lo que se derivan los limites de la democracia electoral sujeta a restricciones fácticas y normativas en un diseño institucional deficiente. Asimismo, la dimensión ciudadana de la democracia se enfrenta a problemas de derechos civiles específicos de las minorías, desigualdades socioeconómicas, participación electoral y ausencia de instituciones de participación.Chile has a very good image on international rankings about its transition to democracy and democratic performance.

These weaknesses originated in the limits to popular sovereignty grounded on the Constitution where it was consecrated political exclusions through the electoral bi-nominal system.

Así, con el paso del tiempo, el conejo se ha terminado por transformar en nuestro país en un verdadero "convidado de piedra".This work analyses the relationship between human beings and their environment taking into consideration the adjustment and eventual invasión of rabbits in Chile. It argües that in the long run, human actions have unsuspected effects upon the environment. In fact rabbits were seen initially as an opportunity for economic development because of the exploitation of their meat and skin. Later, rabbits became a plague in different áreas of Central Chile, Tierra del Fuego and Juan Fernández islands, which was difficult to control. Over the years rabbits became unwelcome guests in Chile.

  6. Ridge-trench collision in Archean and Post-Archean crustal growth: evidence from southern Chile

    International Nuclear Information System (INIS)

    The growth of continental crust at convergent plate margins involves both continuous and episodic processes. Ridge-trench collision is one episodic process that can cause significant magmatic and tectonic effects on convergent plate margins. Because the sites of ridge collision (ridge-trench triple junctions) generally migrate along convergent plate boundaries, the effects of ridge collision will be highly diachronous in Andean-type orogenic belts and may not be adequately recognized in the geologic record. The Chile margin triple junction (CMTJ, 46 deg S), where the actively spreading Chile rise is colliding with the sediment-filled Peru-Chile trench, is geometrically and kinematically the simplest modern example of ridge collision. The south Chile margin illustrates the importance of the ridge-collision tectonic setting in crustal evolution at convergent margins. Similarities between ridge-collision features in southern Chile and features of Archean greenstone belts raise the question of the importance of ridge collision in Archean crustal growth. Archean plate tectonic processes were probably different than today; these differences may have affected the nature and importance of ridge collision during Archean crustal growth. In conclusion, it is suggested that smaller plates, greater ridge length, and/or faster spreading all point to the likelihood that ridge collision played a greater role in crustal growth and development of the greenstone-granite terranes during the Archean. However, the effects of modern ridge collision, and the processes involved, are not well enough known to develop specific models for the Archean ridge collison

    The seasonal variability of the hydrology and the poleward subsurface Peru-Chile Undercurrent (PCUC) off the central Chilean coast (29-41°S) were examined using a high-resolution regional model. The model realistically reproduced observed sea level variability, such as intense anticyclonic eddies, the offshore intensification of the poleward flow and the reduced nearshore equatorward flow during autumn, as well as the equatorward intensification of nearshore meandering flow during spring. Values for geostrophic eddy kinetic energy were high along the coast between 30° and 37°S, and lower south of this area. The modelled poleward undercurrent showed latitudinal variability in velocity and transport. The maximum average transport reported was 0.8 Sv near 30°S, consistent with previous modelling studies and estimations derived from in situ observations. The poleward reduction in undercurrent strength was shown to be partly generated by the poleward decrease in wind stress curl and by the formation of a westward jet near 35°S associated with westward-propagating eddies. A Lagrangian analysis of the modelled water parcels transported by the undercurrent shows that only 14-20% of the subsurface floats transported by the undercurrent upwelled into the surface layer within the subsequent six months after their release. The floats remaining within the subsurface layer were likely transported further south by the current, offshore by westward-propagating eddies or equatorward by the deeper part of the surface coastal current.

    Induced resistance in plants is a systemic response to certain microorganisms or chemicals that enhances basal defense responses during subsequent plant infection by pathogens. Inoculation of chile pepper with zoospores of non-host Phytophthora nicotianae or the chemical elicitor beta-aminobutyric acid (BABA) significantly inhibited foliar blight caused by Phytophthora capsici. Tissue extract analyses by GC/MS identified conserved change in certain metabolite concentrations following P. nicotianae or BABA treatment. Induced chile pepper plants had reduced concentrations of sucrose and TCA cycle intermediates and increased concentrations of specific hexose-phosphates, hexose-disaccharides and amino acids. Galactose, which increased significantly in induced chile pepper plants, was shown to inhibit growth of P. capsici in a plate assay. PMID:26020237

    2012-04-01

    Full Text Available This paper presents an investigation into the relationship between the announcement of mergers and acquisitions, the existence of positive abnormal returns for shares of these firms, and market efficiency in Argentina, Brazil and Chile. Statistically significant Standardized Abnormal Returns were present in the event announcement and the following days in Argentina and Chile and on the event day in Brazil, confirming value creation signaling. Furthermore, the significance of abnormal returns in the event window, namely in the 5 days following the event in Argentina and Chile and the absence of such in Brazil suggests a more efficient market exists in Brazil, in keeping with the semi-strong market efficiency hypothesis. The absence of semi-strong efficient market behavior could prove valuable to investors who could use a window of a few days after the event announcement to accumulate abnormal returns, provided the appropriate research into news of possible mergers or acquisitions has been made.

  18. Immigrant health workers in Chile: is there a Latin American "brain drain"?

    Cabieses, Baltica; Tunstall, Helena

    2012-08-01

    Most research on the phenomenon of "brain drain" (one-way flow of highly skilled/educated individuals) has focused on movement between the least developed and most highly developed countries. Therefore, the significance of patterns of migration to middle-income countries such as those in Latin America is less clear. The aim of this study was to outline key features of international health worker "brain drain" to Chile to promote discussion and further research on this phenomenon as it pertains to the Latin American region. The study compared immigrant health workers living in Chile to both Chilean-born health workers and other immigrants living in Chile using a qualitative nationwide dataset (the results of Chile's 2009 National Socioeconomic Characterization Survey). Demographic, socioeconomic, and health-related variables were included in the analyses, which were weighted by population to obtain nationally representative estimates. In 2009, immigrant health workers represented 2.2% of all health personnel and 2.6% of all resident immigrants in the country. While most immigrant health workers had a universitylevel education, about 25% had only a high school-level education or less. There was no statistically significant difference between the distribution of immigrant health workers' household income and that of Chilean-born health workers. A significantly higher proportion of the immigrant group reported no entitlement to health care provision. While the results of this study do not indicate a significant international health worker "brain drain" to Chile, they do suggest distinctive patterns of migration within the Latin American region. Future studies in Chile could confirm the validity of these results, using a larger sample of immigrant health workers. PMID:23099879

In the period 1981-1991, 62 Agency projects with allotments amounting to over $7 million were completed or are under implementation. Through this co-operation Chile has received 360 man-months of expert services, $3.4 million worth of equipment, and 105 fellowships for some 390 man-months of training. In addition, 262 Chileans attended 219 Agency regional and interregional training courses, and Chilean institutions were awarded 40 research contracts worth over $325,000. This evaluation covers ten years of Agency technical co-operation with Chile, during which 35 projects were completed and 27 are still being implemented. Eight major sectors received assistance: general atomic energy development; nuclear physics; nuclear raw materials; nuclear engineering and technology; nuclear techniques in agriculture; nuclear medicine; hydrology; and nuclear safety. The evaluation concluded that, overall, the Agency's technical co-operation activities have, in keeping with the national priorities concerning peaceful nuclear applications, contributed substantially to the establishment of Chile's nuclear scientific and technical infrastructure, and played a major role in Chile's efforts to introduce nuclear applications in a number of sectors of the economy, with many benefits for broader national development objectives. Another strength of the Agency's programme with Chile is the high level of commitment and dedication that was noted in the great majority of recipient institutions, and in particular at the Comision Chilena de Energia Nuclear, CChEN. Mention should also be made of the fact that bureaucracy appears to be less severe than in some other developing countries, and that constraints that frequently affect other countries, such as insufficient counterpart commitment and lack of continuity of

    Full Text Available The development and the current state of behavioral studies in Chile was analyzed considering articles on Chilean fauna published between 1984 and 1998 (203 articles. The number of articles on the subject of animal behavior has increased significantly along the period studied, indicating an increasing interest on this research. However, the international impact of Chilean research has been comparatively low. Proposals to stimulate the development of this research area in Chile are: i that main research universities in Chile recruit well-trained behavioral ecologists. This will have immediate impact by increasing the number of courses in animal behavior, which will attract a new generation of biology students into this area, promoting the persistence and growth of the Chilean Ethological Society, and stimulating research in animal behavior; and ii that Chilean scientists working in animal behavior establish academic links with foreign colleagues specifically trained in this area.El desarrollo y estado actual de los estudios sobre conducta animal en Chile fueron analizados considerando los artículos sobre fauna de Chile publicados entre 1984 y 1998 (203 artículos.

Sin embargo, el impacto internacional de la investigación chilena ha sido comparativamente bajo. Las propuestas para estimular el desarrollo de esta disciplina en Chile son: i que las principales universidades que priorizan la investigación científica contraten a ecólogos del comportamiento bien entrenados. Esto tendrá un impacto inmediato incrementando el número de cursos en comportamiento animal, lo que atraerá a una nueva generación de biólogos hacia este campo, promoverá la persistencia y el crecimiento de la Sociedad Chilena de Etología, y estimulará la investigación en comportamiento animal

  1. Miocene Vetigastropoda and Neritimorpha (Mollusca, Gastropoda) of central Chile

    Nielsen, Sven N.; Frassinetti, Daniel; Bandel, Klaus

    2004-09-01

    Species of Vetigastropoda (Fissurellidae, Turbinidae, Trochidae) and one species of Neritimorpha (Neritidae) from the Navidad area, south of Valparaı´so, and the Arauco Peninsula, south of Concepción, are described. Among these, the Fissurellidae comprise Diodora fragilis n. sp., Diodora pupuyana n. sp., two additional unnamed species of Diodora, and a species resembling Fissurellidea. Turbinidae are represented by Cantrainea sp., and Trochidae include Tegula (Chlorostoma) austropacifica n. sp., Tegula (Chlorostoma) chilena n. sp., Tegula (Chlorostoma) matanzensis n. sp., Tegula (Agathistoma) antiqua n. sp., Bathybembix mcleani n. sp., Gibbula poeppigii [Philippi, 1887] n. comb., Diloma miocenica n. sp., Fagnastesia venefica [Philippi, 1887] n. gen. n. comb., Fagnastesia matanzana n. gen. n. sp., Calliostoma mapucherum n. sp., Calliostoma kleppi n. sp., Calliostoma covacevichi n. sp., Astele laevis [Sowerby, 1846] n. comb., and Monilea riorapelensis n. sp. The Neritidae are represented by Nerita (Heminerita) chilensis [Philippi, 1887]. The new genus Fagnastesia is introduced to represent low-spired trochoideans with a sculpture of nodes below the suture, angulated whorls, and a wide umbilicus. This Miocene Chilean fauna includes genera that have lived at the coast and in shallow, relatively warm water or deeper, much cooler water. This composition therefore suggests that many of the Miocene formations along the central Chilean coast consist of displaced sediments. A comparison with different fossil and Recent faunas from around the Pacific and South America indicates that the vetigastropod and neritid fauna from the Miocene of Chile has only minor affinities with taxa living near New Zealand, Argentina, and the tropical eastern Pacific at that time.

    Intravenous antimicrobial consumption has not been evaluated previously in Chile. In order to know this consumption (in DDD per 100 bed days), associated factors and antimicrobial control systems across the country, a questionnaire was sent to evaluate these features during 2005. A total of 29 public hospitals and private clinics answered this poll, 20 belonging to the public health system (69%). Only 48.1% declared to have an independent antimicrobial committee and 17.2% allowed unrestricted antimicrobial use. Glycopeptides and carbapenems were the most regulated compounds (75.9 and 82.8%, respectively). Antimicrobial controls systems were more frequently declared among public hospitals and only non-public hospitals permitted free use of antimicrobials. Global consumption reached 59.98 DDD per 100 bed-days, with beta-lactams representing 74.3% of this consume (44.57 DDD per 100), and cephalosporins 43% (25.78 DDD per 100). Chloramphenicol, penicillin G and cloxacillin use was significantly higher among public hospitals. The opposite was observed for imipenem-cilastatin, linezolid, cefuroxime and caspofungin with higher consumes observed among non-public hospitals. In a multivariate analysis, increased cefazolin use was independently associated with sites allowing unrestricted use, and ciprofloxacin consumption with non-public hospitals. Institutions with decreased susceptibility to imipenem-cilastatin among non-fermentative gram negative bacilli showed a higher use of this compound and linezolid consumption paralleled vancomycin-resistant enterococci prevalence. It is necessary to reinforce governmental regulations about antimicrobial use issued during 1999. PMID:19194604

    Quantitative geomorphology regroups a large number of interesting tools to characterize natural basins across scales. The application of these tools to several river basins allows the description and comparison of geomorphological properties at different spatial scales as oppose to more traditional descriptors that are typically applied at a single scale, meaning the catchment scale. Most of the recent research using these quantitative geomorphological tools has focused on open catchments and no specific attention has been given to endorheic basins, and the possibility of having particular features that distinguish them from exorheic catchments. The main objective of our study is to characterize endorheic basins and investigate whether these special geomorphological features can be identified. Because scaling invariance is a widely observed and relatively well quantified property of open basins, it provides a suitable tool to characterize differences between the geomorphology of closed and open basins. Our investigation focuses on three closed basins located in northern Chile which describe well the diversity in the geomorphology and geology of this arid region. Results show that endhoreic basins exhibit different slope-area and flow paths sinuosity regimes compared to those observed in open basins. These differences are in agreement with the particular self-similar behavior across spatial scales of the Euclidean length of subcatchments, as well as the Hack's law and Horton's ratios. These regimes imply different physical processes inside the channel network regardless of the basin area, and they seem to be related to the endorheic character of these basins. The analysis of the probability density functions of contributing areas and lengths to the lower region shows that the hypothesis of self-similarity can also be applied to closed basins. Theoretical expressions for these distributions were derived and validated by the data. Future research will focus on (1

    A study was conducted during 1995-96 to evaluate Se concentration in water, sediment, and plants from aquatic ecosystems of central Chile, an area particularly affected by mining activities. Samples were collected from Panquehue, Chagres, and Ocoa along the Acongua River (presumably receives discharges from a copper refinery and a copper mine). Samples were also collected from one site on the Puchuncavi Stream (directly contaminated by both a coal power plant and a copper refinery). In addition, samples were also collected from one site on the Limache Stream (an urban area with no Se-contaminating sources). The sediment and plant samples collected in Puchuncavi had higher Se levels, which were statistically different to the concentration in samples from other sites. Sediments from Puchuncavi and Ocoa had the highest levels of Se (520 plus or minus 46 and 440 plus or minus 10 {mu} g/kg, respectively) while the plant (Jussiaea repens (Ludwigia repens)) collected in Puchuncavi had an Se concentration 6.5 times higher than the sample collected in Panquehue (116 plus or minus 154 and 182 plus or minus 54 {mu} g/kg, respectively). Puchuncavi water had more acidic pH than water from the other sites thus decreasing Se solubility. Se concentrations in sediment and water collected in Chagres were lower than the concentration determined in sediment and water from either Ocoa or Panquehue. Plant/water and plant/sediment accumulation factors and a sediment/water distribution factor were similar for all sampling sites, except Puchuncavi (accumulation and distribution factors are higher than at the other sites). Hydrocotyle ranunculoides had practically the same plant/sediment accumulation factor at all sites while the accumulation factor for J. repens varied according to site. The samples collected in the Limache stream had Se at equal or even higher concentration than the other samples collected from presumably contaminated sites (except Puchuncavi). 19 refs.

    We examine the appearance of the ozone hole over a populated area with more than 100,000 inhabitants. The largest population concentrations on the South American continent nearest the ozone hole region are Punta Arenas, Chile (53.0°S, 70.9°W) and Ushuaia, Argentina (54.5°S, 68.0°W), located close to the strait of Magallanes, opposite the Antarctic Peninsula. A special field mission was held in Punta Arenas, in September-October 1995 to investigate the vertical distribution of ozone during the appearance of the Antarctic ozone hole. Previous work has shown that the city of Punta Arenas is located at the edge of the hole area and is affected every year during a few days in the October period. The ozone trend near these locations is -0.5% per year using the yearly averages and -1.2% per year using the October means. This trend is 2 to 5 times larger than the global average. Several ozonesondes of the electrochemical concentration cell type were launched from Punta Arenas to determine the vertical distribution of ozone during "normal" and "perturbed" conditions. The ozone hole passed over Punta Arenas on October 12, 13 and 14, 1995. In addition to the sondes, which were launched once a day, ozone column amounts and UVB radiation were measured with a ground-based ozone Brewer spectrophotometer. The strongest ozone depletion over Punta Arenas in 1995 occurred on October 13, when the ozone column decreased from a "normal" value of about 325 Dobson Units (DU) to 200 DU; the vertical distribution of ozone on October 13 compared with October 6 shows depleted ozone roughly 50% less during hole conditions in the stratosphere. The UVB intensities have increased accordingly. The spectral ratio for October 13 to October 4 is 13 times larger at 297 nm.

    The emergence of old and new communicable diseases is becoming an important public health problem in industrialized and developing countries worldwide. Chile experienced, at the end of the seventies and during the eighties, epidemics of several emergent communicable infectious diseases whose relevance as public health problems had steadily decreased in the previous 25 years. The most striking of these epidemics was a severe outbreak of typhoid fever that lasted at least 10 years. The majority of the cases occurred in the urban setting of Santiago. Several investigators suggested, in light of apparently good sanitation statistics, that factors responsible for this outbreak of typhoid were an increase in the number of chronic carriers of Salmonella typhi, the lack of microbiological food controls and the consumption of vegetables irrigated with waste water contaminated with S typhi. However, there is a dearth of epidemiological information and field work confirming the role of these factors in this typhoid outbreak. Moreover, the sudden, massive and urban characteristics of this epidemic, coupled to contemporary information regarding shortcomings on the preparation of drinking water and on decreased availability of drinking water to the population in Santiago regardless of good sanitation statistics, suggest that this outbreak may have been partially waterborne. The beginning of this typhoid outbreak also coincided with increased rain fall, with rapidly deteriorating economic and social conditions manifested in high rates of unemployment, and with decreased government investment on social services, including sanitation and health. All these factors are known to influence the epidemiology of typhoid and other emergent diseases worldwide. PMID:9460291

    Full Text Available Chile has become a major actor in the blueberry industry as the most important supplier of off-season fresh fruit for the northern hemisphere. Blueberry exports passed from US$ 30 million (around 4,000 tons in 2000 to US$ 380 million (94,000 tons in 2011. The characteristics of the major blueberry growing regions (North, Central, South-central and South are presented in terms of acreage, varieties, management practices, extension of the harvest season, and soil and climatic conditions. Most fruit is from highbush varieties, picked by hand and exported fresh by boat to United States. Largest proportion of fruit is exported from mid December to late January, which coincides with lowest prices. The south-central region (latitudes 34º50' to 38º15' S was in 2007 the most important one with 5,075 ha (51.1% of area planted. Among the challenges for the Chilean blueberry industry in the near future are: 1. Lower profitability due to lower rates of currency exchange and higher costs, 2 - Greater scarcity and higher cost of labor, 3.- Need for higher productivity and sustainable production practices, 4- Fruit of high and consistent quality, and 5.- Greater investment in research. As a case study the article presents three approaches that can help identify areas with low availability of labor and improve its efficiency. The article shows the use of geomatic tools to establish labor availability, application of growth regulators to reduce crop load, increase fruit size and improve harvest efficiency, and the use of shakers to harvest fresh fruit for long distance markets. More research is needed to improve yields, reduce costs and give greater economical and ecological sustainability to the Chilean blueberry industry.

    2016-01-01

    A common challenge for government administrations that aim to improve the delivery of information and services to citizens is to go beyond a government-centred approach. By focusing on citizens and the needs of a wide range of citizens, Universal Design (UD) can help to increase the effectiveness, efficiency and satisfaction of government services. This paper examines the case of an internationally recognised Chilean government service delivery programme inspired by UD principles known as ChileAtiende ("ChileService"). A brief account of its creation and current status is provided. PMID:27534348

    Full Text Available Este ensayo presenta las nuevas tendencias de los feminismos en Chile y analiza cómo pasaron a ser parte del texto social. El trabajo discute el hecho de que los discursos feministas, luego de la dictadura (1973-1990, continúan sin cuestionar la categoría "mujeres", que generaliza y suprime las diferencias de clase y raza entre ellas mismas. Tal presupuesto es analizado frente al acuerdo de los gobiernos democráticos chilenos con los intereses de la oligarquía y de la iglesia católica en la manutención del status quo.Parte de este compromiso viene restringiendo los discursos feministas a la estructura familiar nuclear, de forma que temas como clase, raza y sexualidad no alcanzan a ser enteramente problematizadas. En la medida en que las feministas chilenas no están cuestionando su lugar de enunciación, problemas como derecho reproductivo o el acceso de las mujeres al espacio público continúan siendo vistos desde una perspectiva privilegiada, que anula las discriminaciones existentes entre las mujeres.This essay is about the new trends on Chilean feminisms and how they have become part of the social text. The paper discusses how feminist discourses after dictatorship (1973-1990 remain without putting into question the category of "women" as a generalization that erases class and racial differences among women. This is analyzed in the context of the compromise made by Chilean democratic governments with the interests of oligarchy and the Catholic Church in order to maintain the status quo. Part of this compromise has constrained feminist discourses to the nuclear family frame, within which class, race and sexuality cannot be fully problematized. Since Chilean feminists are not questioning their place of enunciation, problems such as reproductive rights or women access to the public space continue to be seen from a privileged perspective that obliterates the existing discriminations among women.

    Full Text Available The paper measures and evaluates technical efficiency among pension fund managers in Chile. Recent pension reform has established pension fund management market in nine countries in Latin America. The new pension providers compete for affiliates on the basis of fees, rates of return, and quality of service, and are subject to extensive regulation. Applying data envelopment analysis to data from Chile 1982-1999, the paper examines issues of efficiency, competition, and regulation. The analysis concludes that pension fund managers operate below the estimated "efficiency frontier", and there is no evidence of a sustained upward trend in technical efficiency over time.Este artigo se propõe a avaliar e medir a eficiência técnica dos administradores de fundos de previdência privada no Chile. A recente reforma sofrida pela previdência deu lugar a um mercado de gestão de fundos de aposentadoria em nove países da América Latina.

  17. Geyser Interaction: Two examples from El Tatio, Chile

    2015-04-01

    Geysers are eruptive hot springs that episodically discharge steam, liquid water, and non-condensable gases. While hot springs are abundant in geothermal areas, geysers are uncommon and they require special conditions of water supply, heat flow, and fractures and/or porous rocks. Despite more than 200 years of study, there are still open questions about how and why geysers erupt: How is geyser cycle influenced by other adjacent and distant thermal sources? Are hot springs and geyser connected through permeable pathways? Why do only a few hot springs erupt as geysers? We conducted two week-long field studies of geyser interactions in the El Tatio geyser field, Chile during Oct. 2012 and Oct. 2014. We found two different cases: geyser-pool interaction and geyser-geyser interaction. In the first case, we documented how the water level of the pool varies as the geyser eruption evolves. Measured temperature in the geyser conduit has a repeatable pattern, when it reaches boiling the eruption occurs. In contrast, the temperature in the adjacent pool is constant and never reaches the boiling point, suggesting that heat is supplied only to the geyser conduit. Pressure in the geyser conduit and pool have a similar evolution over time so that the side pool acts as a barometer for the conduit. The geyser-geyser interaction was documented in 2014. A geyser with long eruption intervals (1-3 hours) changes the behavior of a short-interval geyser (c.a. 10 minutes). When the long-interval geyser erupts, the short-interval geyser stops erupting. When the eruption of the long-interval geyser becomes less vigorous, the short-interval geyser resumes its eruptions with shorter intervals. During the week of measurements in 2012, we did not observe the short-interval geyser erupting. At that time, the eruption of the long-interval geyser was regular (4 hours and 40 minutes, ref 1). We thus infer that the geyser-geyser interaction made the eruption cycle chaotic. Geyser-pool and geyser

    Full Text Available The oxidation capacity of the highly polluted urban area of Santiago, Chile has been evaluated during a summer measurement campaign carried out from 8–20 March 2005. The hydroxyl (OH radical budget was evaluated employing a simple quasi-photostationary-state model (PSS constrained with simultaneous measurements of HONO, HCHO, O3, NO, NO2, j(O1D, j(NO2, 13 alkenes and meteorological parameters. In addition, a zero dimensional photochemical box model based on the Master Chemical Mechanism (MCMv3.1 has been used to estimate production rates and total free radical budgets, including OH, HO2 and RO2. Besides the above parameters, the MCM model has been constrained by the measured CO and volatile organic compounds (VOCs including alkanes and aromatics. Both models simulate the same OH concentration during daytime indicating that the primary OH sources and sinks included in the simple PSS model predominate. Mixing ratios of the main OH radical precursors were found to be in the range 0.8–7 ppbv (HONO, 0.9–11 ppbv (HCHO and 0–125 ppbv (O3. The alkenes average mixing ratio was ~58 ppbC accounting for ~12% of the total identified non-methane hydrocarbons (NMHCs. During the daytime (08:00 h–19:00 h, HONO photolysis was shown to be the most important primary OH radical source comprising alone ~55% of the total initial production rate, followed by alkene ozonolysis (~24% and photolysis of HCHO (~16% and O3 (~5%. The calculated average and maximum daytime OH production rates from HONO photolysis was 1.7 ppbv h−1 and 3.1 ppbv h−1, respectively. Based on the experimental results a strong photochemical daytime source of HONO is proposed. A detailed analysis of the sources of OH radical precursors has also been carried out.

    2002-09-01

    Full Text Available En este estudio se describe el origen y la evolución de dos partidos políticos chilenos (el Partido Radical y el Partido Demócrata Cristiano por medio del análisis de las redes sociales que los originaron y que los componen. Se propone un modelo teórico que consiste en la combinación de un análisis estructural basado en el estudio de redes sociales y en la descripción del sistema simbólico que las retroalimenta. La estructura y función de las redes sociales depende de la dirección en la que se dan los intercambios -redes horizontales y redes verticales-, de lo que se intercambia, y de la articulación que se da entre las redes. En toda sociedad se dan intercambios simétricos y asimétricos, que van conformando redes horizontales y verticales. Estas redes se van articulando entre sí, conformando el tejido social. El predominio de unas sobre otras y su combinación dan el carácter a la cultura política (ejemplo, autoritaria vs. igualitaria. En el caso de Chile encontramos que se trata de una sociedad horizontalmente estructurada en clases sociales, al interior de las cuales se advierten redes sociales informales que eventualmente y por razones ideológicas se van formalizando en partidos políticos. Estos grupos igualitarios de amigos ejercen informalmente control sobre sus propios miembros creando barreras invisibles que los distinguen de los demás, y aunque si bien es cierto que en ellos surgen líderes “naturales”, su liderazgo es condicional lo que permite el surgimiento de tendencias y facciones que a su vez pueden llegar a constituirse en nuevos partidos. Por ende, el sistema depende de negociaciones horizontales permanentes mediadas por un fuerte presidencialismo dentro de un sistema parlamentario fuerte y apoyado por una legitimidad casi fanática.

  3. Radiation protection in pediatric interventional cardiology. Current status and challenges in Chile

    International Nuclear Information System (INIS)

    Further actions to improve radiation safety in this medical practice are discussed. All the X-ray systems used in paediatric IC procedures in Chile have been characterized in terms of dose and image quality. In addition, dose rates of scattered radiation to the position of the eyes and ankles of cardiologists have been measured. In May 2010, in Santiago, Chile, a workshop organized by the International Atomic Energy Agency (IAEA) was the starting point for a pilot program on patient dosimetry and medical personnel for Latin America and the Caribbean, with participants from 11 countries. A pilot training course on Radiological Protection was given as part of the program. The first dose values reported for paediatric patients under the pilot program conducted by the IAEA in Latin America and the Caribbean included 70 procedures in Chile later extending to a total of 544 procedures. We think that a fundamental first step to improve IC radiation safety in Chile, would be to revise and update legislation on the use of ionizing radiation, including the implementation of quality assurance programs and training in radiation protection according to those involved in IC procedures

  1. Heat balance and eddies in the Peru-Chile current system

    2012-07-15

    The Peru-Chile current System (PCS) is a region of persistent biases in global climate models. It has strong coastal upwelling, alongshore boundary currents, and mesoscale eddies. These oceanic phenomena provide essential heat transport to maintain a cool oceanic surface underneath the prevalent atmospheric stratus cloud deck, through a combination of mean circulation and eddy flux. We demonstrate these behaviors in a regional, quasi-equilibrium oceanic model that adequately resolves the mesoscale eddies with climatological forcing. The key result is that the atmospheric heating is large (>50 W m{sup -2}) over a substantial strip >500 km wide off the coast of Peru, and the balancing lateral oceanic flux is much larger than provided by the offshore Ekman flux alone. The atmospheric heating is weaker and the coastally influenced strip is narrower off Chile, but again the Ekman flux is not sufficient for heat balance. The eddy contribution to the oceanic flux is substantial. Analysis of eddy properties shows strong surface temperature fronts and associated large vorticity, especially off Peru. Cyclonic eddies moderately dominate the surface layer, and anticyclonic eddies, originating from the nearshore poleward Peru-Chile Undercurrent (PCUC), dominate the subsurface, especially off Chile. The sensitivity of the PCS heat balance to equatorial intra-seasonal oscillations is found to be small. We demonstrate that forcing the regional model with a representative, coarse-resolution global reanalysis wind product has dramatic and deleterious consequences for the oceanic circulation and climate heat balance, the eddy heat flux in particular.

Eleven species were found in this study: Acanthopleura echinata (Barnes, 1824; Callistochiton pulchellus (Gray, 1828; Calloplax vivipara (Plate, 1899, Chaetopleura peruviana (Lamarck, 1819; Chiton cumingsii Frembly, 1827; Chiton granosus Frembly, 1827; Chiton magnificus Deshayes, 1827; Enoplochiton niger (Barnes, 1824, Radsia barnesii (Gray, 1828, Tonicia atrata (G. B. Sowerby II, 1840 and Tonicia chilensis (Frembly, 1827. All of the species occurring in the area have distributions in the southeastern Pacific Ocean, from Ecuador to central Chile, and three of them are species endemic to the Chilean coasts (Calloplax vivipara, Radsia barnesii, and Tonicia atrata. This diversity of species is comparable to that of better surveyed faunas of central and southern Chile or Patagonia. Of the eleven species recorded, the geographic distribution records for Callistochiton pulchellus, Radsia barnesii and Tonicia atrata are extended, and Calloplax vivipara is found alive again after 40 years, filling a gap in its known distribution. Illustrations of living specimens in their habitat, distribution records and a taxonomic key for all the studied taxa are also provided.

    Olive tree varieties that were cultivated only in the Mediterranean basin a few decades ago are now planted in the Southern Hemisphere as well. The chemical composition of the oils produced in countries as far distant as Spain and Chile are affected by differences in latitude and climate. In this work, seven monovarietal virgin olive oils from Chile (Arbequina, Barnea, Frantoio, Koroneiki, Leccino, Manzanilla and Picual) have been characterized by the chemical compounds responsible for taste (phenols) and aroma (volatiles). The oils were produced in five regions of Chile, and the concentration values of some chemical compounds were related to the geographical location of the olive tree orchards. Virgin olive oils from the major cultivars, Arbequina and Picual, were characterized in comparison with the same monovarietal oils produced in Spain. The concentration values of fourteen volatile compounds showed significant differences (p < 0.05) between the oils produced in Spain and Chile. Concerning the phenol composition, main differences were found on the secoiridoids derivatives of oleuropein and ligstroside, apigenin and luteolin. PMID:21090684

  4. Large slope instabilities in Northern Chile and Southern Peru

    Deep canyon incision into Tertiary paleosurfaces and large slope instabilities along the canyon flanks characterize the landscape of western slope of the Andes of northern Chile and South Peru. This area belongs to the Coastal Escarpment and Precordillera and is formed by coarse-grained clastic and volcanoclastic formations. The area is characterized by intense seismicity and long-term hyperaridity (Atacama Desert). Landslides along the canyon flanks affect volumes generally up to 1 km3 and locally evolved in large rock avalanches. We prepared a landslide inventory covering an area of about 30,000 km2, extending from Iquique (Chile) to the South and Tacna (Peru) to the North. A total of 606 landslides have been mapped in the area by use of satellite images and direct field surveys, prevalently including large phenomena. The landslides range from 1 10-3 km2 to 464 km2 (Lluta landslide). The total landslide area, inclusive of the landslide scarp and of the deposit, amounts to about 2,130 km2 (about 7% of the area). The mega landslides can be classified as large block slides that can evolve in large rock avalanches (e.g. Minimini landslide). Their initiation seems to be strongly associated to the presence of secondary faults and large fractures transversal to the slope. These landslides show evidence suggesting a re-incision by the main canyon network. This seems particularly true for the Lluta collapse where the main 'landslide' mass is masked or deleted by the successive erosion. Other landslides have been mapped along the Coastal Escarpment and some of the major tectonic escarpments with an E-W trend. We examined area-frequency distributions of landslides by developing logarithmically binned, non-cumulative size frequency distributions that report frequency density as a function of landslide planar area A. The size frequency distribution presents a strong undersampling for smaller landslides, due to the extremely old age of the inventory. For landslides larger than

    Full Text Available Alstroemeria (Alstroemeriaceae is an endemic genus of South America with two major distribution centers in the continent: Chile and Brazil. In Chile the genus is distributed from the North, near Iquique (20º13’ S, 70º09’ W to the Chilean and Argentine Patagonia (53º10’ S, 70º54’ W. The central zone of Chile presents the highest number of species. A. presliana Herb. grows from Curicó (34º59’ S, 71º14’ W to Cautín (38º45’ S, 72º34’ W in Chile and Neuquén (36º50’ S, 71º05’ W, Argentina. A comparative karyotype study was made between a population of A. presliana subsp. presliana and a population of A. presliana subsp. australis Ehr. Bayer. Both populations presented asymmetric karyotypes, with 2n = 2x = 16 chromosomes, but with different chromosome formulae: A. presliana subsp. presliana has a haploid formula with 4m + 1sm-sat + 1st-sat + 2t, i.e., four pairs ofmetacentric chromosomes, one submetacentric pair with satellite, one subtelocentric pair with satellite, and two telocentrics pairs. A. presliana subsp. australis has a formula with 2m + 1m-sat + 1sm + 4t chromosomes, i.e., two pairs of metacentric chromosomes, one metacentric pair with satellite, one submetacentric pair, and four telocentrics chromosomes. These results indicated that the karyotype of the subspecies is very different, and it would be possible to recognize A. presliana subsp. australis as a new species.Alstroemeria (Alstroemeriaceae es un género endémico de Sudamérica y presenta dos grandes centros de distribución: Chile y Brasil.

    2016-05-01

    The electricity systems in Chile are characterized by a variable hourly demand in the central grid and an almost constant demand in the northern grid, which require different operation strategies for solar power plants depending on their location. Hybridizing a CSP plant with a PV plant can increase the whole plant capacity factor by allowing thermal energy to be stored while the PV plant is in production and thus help to achieve a fully dispatchable solar electricity production system. A thermal and economic analysis of hybrid CSP+PV plants is conducted considering a range of plant capacities based on a parabolic trough plant with the addition of a PV plant for the environmental conditions of Crucero in Northern Chile, which is a hotspot for solar energy development in the country. The study considers a parametric analysis and optimization of the storage and power block sizes for the CSP plant in terms of the levelized cost of energy (LCOE) for varying PV plant nominal capacity. The annual production of the plants are calculated by using the Transient System Simulation program (TRNSYS), which uses a new component library developed for that purpose. The results show good agreement with other software packages as well as with actual data from currently operating CSP plants. The adopted approach helps the proper assessment of the integration of different technologies, since it uses the well-kwon modular structure of the TRNSYS. Regarding the potential for the hybrid solar-solar plants in the Atacama Desert, the high level of irradiation available in Chile can provide a competitive electricity cost, allowing to investors the access to PPA contracts with mining companies in northern Chile. Additionally, the optimization analysis shows that the northern regions of Chile present an outstanding potential for the deployment of such projects.

  8. The evolution of seabirds in the Humboldt Current: new clues from the Pliocene of Central Chile.

    Directory of Open Access Journals (Sweden)

    Martín Chávez Hoffmeister

    Full Text Available BACKGROUND: During the last decade, new Neogene fossil assemblages from South America have revealed important clues about the evolution of seabird faunas in one of the major upwelling systems of the world: the Humboldt Current. However, most of this record comes from arid Northern Chile and Southern Peru and, in consequence, our knowledge of the evolutionary history of seabirds in the temperate transitional zone is negligible. A new Late Pliocene assemblage of fossil birds from the coastal locality of Horcon in Central Chile offers a unique opportunity to fill this gap. PRINCIPAL FINDINGS: Isolated bones of a medium-sized penguin are the most abundant bird remains. Morphological and cladistic analyses reveal that these specimens represent a new species of crested penguin, Eudyptes calauina sp. nov. Eudyptes is a penguin genus that inhabit temperate and subantarctic regions and currently absent in central Chile. Additionally, a partial skeleton of a small species of cormorant and a partial tarsometatarsus of a sooty shearwater have been identified. CONCLUSION/SIGNIFICANCE: The Horcon fossils suggest the existence of a mixed avifauna in central Chile during the Pliocene in concordance with the latitudinal thermal gradient. This resembles the current assemblages from the transitional zone, with the presence of species shared with Northern Chile and Southern Peru and a previously unrecorded penguin currently absent from the Humboldt System but present in the Magellanic region. Comparison of Pliocene seabird diversity across the Pacific coast of South America shows that the Horcon avifauna represents a distinctive assemblage linking the living faunas with the Late Miocene ones. A comparison with the fossil record near the Benguela Current (west coast of southern Africa suggests that the thermic gradient could play an important role in the preservation of a higher diversity of cold/temperate seabirds in the Humboldt Current.

    Chagas disease, which ranks among the world's most neglected diseases, is a chronic, systemic, parasitic infection caused by the protozoan Trypanosoma cruzi. Mepraia species are the wild vectors of this parasite in Chile. Host-parasite interactions can occur at several levels, such as co-speciation and ecological host fitting, among others. Thus, we are exploring the interactions between T. cruzi circulating in naturally infected Mepraia species in all areas endemic of Chile. We evaluated T. cruzi infection rates of 27 different haplotypes of the wild Mepraia species and identified their parasite genotypes using minicircle PCR amplification and hybridization tests with genotype-specific DNA probes. Infection rates were lower in northern Chile where Mepraia gajardoi circulates (10-35%); in central Chile, Mepraia spinolai is most abundant, and infection rates varied in space and time (0-55%). T. cruzi discrete typing units (DTUs) TcI, TcII, TcV, and Tc VI were detected. Mixed infections with two or more DTUs are frequently found in highly infected insects. T. cruzi DTUs have distinct, but not exclusive, ecological and epidemiological associations with their hosts. T. cruzi infection rates of M. spinolai were higher than in M. gajardoi, but the presence of mixed infection with more than one T. cruzi DTU was the same. The same T. cruzi DTUs (TcI, TcII, TcV, and TcVI) were found circulating in both vector species, even though TcI was not equally distributed. These results suggest that T. cruzi DTUs are not associated with any of the two genetically related vector species nor with the geographic area. The T. cruzi vectors interactions are discussed in terms of old and recent events. By exploring T. cruzi DTUs present in Mepraia haplotypes and species from northern to central Chile, we open the analysis on these invertebrate host-parasite interactions. PMID:26771702

    Full text: The extremely arid condition of northern Chile is the main obstacle to the present and future development of urban centres and economic activities in the region. The existing water resources are scarce. During the last decade, isotope techniques have been applied to investigate aspects such as the origin and residence time of the groundwater, these being extremely important for water development and water management. This paper presents 18O and 34S data in aqueous sulphate, as well as 18O, 2H, and 3H from springs, rivers and groundwater samples of the Pampa del Tamarugal and Salar de Llamara basins. The principal aim of this study was to investigate the isotope evolution of the sulphate, the origin of the sulphur, the groundwater flow path, and the possibility of using the 18O of the sulphate as a tracer for estimation of the residence time of the groundwater. Springs that have their recharge area in the high Altiplano (Salar del Huasco basin) show δ values between +5.0 per mille and +6.0 per mille for the 18O and +5.0 per mille and +9.0 per mille for the 34S isotope. Springs from lower altitude, show an isotope content between + 8.6 per mille and + 10.6 per mille for 18O and +7.4 per mille and + 11.7 per mille for 34S. The groundwaters in the Pampa aquifers, based on their hydrogen and oxygen isotope composition, are associated with different recharge areas. However, these waters show an isotope range for the sulphate similar to .he one of the springs, and no clear relationships are observed between isotope content, flow path and residence time. This pattern could be related to the poorly defined aquifer systems present in the Pampa. The Llamara groundwaters have a uniform isotope content and are the most enriched in the region (δ18O = -6.0 per mille and δ2H = -50 per mille). The isotope composition of their sulphate compares well with the Pampa groundwater, indicating a similar sulphate source. The isotope composition of gypsum deposits in the

    Full Text Available The Panulcillo skarn copper deposit developed in an Early Cretaceous (Valanginian volcano-sedimentary sequence intruded by a Cretaceous diorite. The exoskarn zone of the deposit is composed of garnet skarn comprising grandite garnet (Ad12.9-47.4 and phlogopite with lesser amounts of diopside (Di89.6-91.6, clintonite, pargasitic hornblende, actinolite, pumpellyite, chlorite, quartz and calcite, exhibiting characteristic Mg-Al-rich assemblages. The principal ores consist of chalcopyrite, monoclinic pyrrhotite, sphalerite, pyrite, and magnetite with small amounts of galena, and locally secondary marcasite, hematite and covellite, generally filling interstices of the garnet skarn. Chalcopyrite shows characteristic polysynthetic twinning, normally including fine star-like crystals of sphalerite as exsolution products. Sphalerite contains 14.4 - 22.5 mol% FeS and 1.6 - 9.2 mol% MnS, and is associated intimately with chalcopyrite. It is highly likely that such Fe-rich sphalerite has coexisted primarily with hexagonal pyrrhotite under low-sulfidation conditions at higher temperatures than 275 - 254°C, below which monoclinic pyrrhotite is stableMineralogía del yacimiento cuprífero tipo skarn de Panulcillo, Región de Coquimbo, Chile.

  16. Energy and Mass Balance At Gran Campo Nevado, Patagonia, Chile

    Schneider, C.; Kilian, R.; Casassa, G.

    The Gran Campo Nevado (GCN) Ice Cap on Peninsula Muñoz Gamero, Chile, is lo- cated in the southernmost part of the Patagonian Andes at 53S. It comprises an ice cap and numerous outlet glaciers which mostly end in proglacial lakes at sea level. The total ice covered area sums up to approximately 250 km2. GCN forms the only major ice body between the Southern Patagonian Icefield and the Street of Magallan. Its almost unique location in the zone of the all-year westerlies makes it a region of key interest in terms of glacier and climate change studies of the westwind zone of the Southern Hemisphere. Mean annual temperature of approximately +5C at sea level and high precipitation of about 8.000 mm per year lead to an extreme turn-over of ice mass from the accumulation area of the GCN Ice Cap to the ablation areas of the outlet glaciers. Since October 1999 an automated weather station (AWS) is run continuously in the area at Bahia Bahamondes for monitoring climate parameters. From February to April 2000 an additional AWS was operated on Glaciar Lengua a small outlet glacier of GCN to the north-west. Ablation has been measured at stakes during the same pe- riod. The aim of this study, was to obtain point energy and mass balance on Glaciar Lengua. The work was conducted as part of the international and interdisciplinary working group SGran Campo NevadoT and supported by the German Research Foun- & cedil;dation (DFG). Energy balance was calculated using the bulk approach formulas and calibrated to the measured ablation. It turns out, that sensible heat transfer is the major contribution to the energy balance. Since high cloud cover rates prevail, air tempera- ture is the key factor for the energy balance of the glacier. Despite high rain fall rates, energy input from rain fall is of only minor importance to the overall energy balance. From the energy balance computed, it was possible to derive summer-time degree-day factors for Glaciar Lengua. With data from the nearby

    Contrary to the intentions of electoral engineers, Chile's binomial system has failed to fundamentally transform the party system. It may seem that the debate on electoral reform is, therefore, irrelevant, because whatever election system is implemented, parties will simply adopt electoral strategies to ensure their survival. This article acknowledges that electoral reform, whatever its nature, is unlikely to significantly affect the number of parties in Chile. However, it argues that by focu...

    Tuberculosis (TB), caused by the pathogen Mycobacterium tuberculosis (MTB), remains a disease of high importance to global public health. Studies into the population structure of MTB have become vital to monitoring possible outbreaks and also to develop strategies regarding disease control. Although Chile has a low incidence of MTB, the current rates of migration have the potential to change this scenario. We collected and analyzed a total of 458 M. tuberculosis isolates (1 isolate per patient) originating from all 15 regions of Chile. The isolates were genotyped using the spoligotyping method and the data obtained were analyzed and compared with the SITVIT2 database. A total of 169 different patterns were identified, of which, 119 patterns (408 strains) corresponded to Spoligotype International Types (SITs) and 50 patterns corresponded to orphan strains. The most abundantly represented SITs/lineages were: SIT53/T1 (11.57%), SIT33/LAM3 (9.6%), SIT42/LAM9 (9.39%), SIT50/H3 (5.9%), SIT37/T3 (5%); analysis of the spoligotyping minimum spanning tree as well as spoligoforest were suggestive of a recent expansion of SIT42, SIT50 and SIT37; all of which potentially evolved from SIT53. The most abundantly represented lineages were LAM (40.6%), T (34.1%) and Haarlem (13.5%). LAM was more prevalent in the Santiago (43.6%) and Concepción (44.1%) isolates, rather than the Iquique (29.4%) strains. The proportion of X lineage was appreciably higher in Iquique and Concepción (11.7% in both) as compared to Santiago (1.6%). Global analysis of MTB lineage distribution in Chile versus neighboring countries showed that evolutionary recent lineages (LAM, T and Haarlem) accounted together for 88.2% of isolates in Chile, a pattern which mirrored MTB lineage distribution in neighboring countries (n = 7378 isolates recorded in SITVIT2 database for Peru, Brazil, Paraguay, and Argentina; and published studies), highlighting epidemiological advantage of Euro-American lineages in this region

Se logró obtener un aislado viral, denominado RP5, a partir de casos clínicos diagnosticados como enfermedad hemorrágica de los cachorros. Este aislado inoculado en monocapas celulares produce el típico efecto citopático de miembros de la subfamilia alphaherpesvirinae, familia Herpesviridae: lisis celular a tiempos cortos. Este aislado manifiesta este efecto tanto en cultivos primarios de pulmón y riñón canino, como también en la línea celular MDCK. Este efecto se pierde al preincubar el inóculo con solventes orgánicos, lo cual indica presencia de envoltura lipoproteica, lo cual descartaría la presencia de VAC-1 en este aislado. Como segunda confirmación de la presencia de VHC-1 en los cultivos celulares inoculados se procedió a realizar una prueba de inmunofluorescencia directa, utilizando un anticuerpo monoclonal anti VHC-1, conjugado con isotiocianato de fluoresceína (VMRD, Inc., cuyos resultados señalan inequívocamente la presencia del virus. Determinar la presencia del virus es de gran importancia, pues al aislar y caracterizar el virus se podrá contar con un instrumento imprescindible para realizar futuras investigaciones.

    The Meseta Chile Chico (MCC, 46.4°S) is the westernmost exposure of Eocene (lower basaltic sequence, LBS; 55-40 Ma, K-Ar ages) and Mio-Pliocene (upper basaltic sequence, UBS; 16-4 Ma, K-Ar ages) flood basalt volcanism in Patagonia. The MCC is located south of the Lago General Carrera-Buenos Aires (LGCBA), southeast from the present day Chile Triple Junction (CTJ), east of the actual volcanic gap between Southern South Volcanic Zone and Austral Volcanic Zone (SSVZ and AVZ, respectively) and just above the inferred location of the South Chile Ridge segment subducted at ˜6 Ma (SCR-1). Erupted products consist of mainly ne-normative olivine basalt with minor hy-normative tholeiites basalt, trachybasalt and basanite. MCC lavas are alkaline (42.7-53.1 wt.% SiO 2, 3-8 wt.% Na 2O+K 2O) and relatively primitive (Ni: 133-360 ppm, Cr: 161-193 ppm, Co: 35-72 ppm, 4-16.5 MgO wt.%). They have a marked OIB-like signature, as shown by their isotopic compositions ( 87Sr/ 86Sr o=0.70311-0.70414 and ɛNd=+4.7-+5.1) and their incompatible trace elements ratios (Ba/La=10-20, La/Nb=0.46-1.09, Ce/Pb=15.52-27.5, Sr/La1, Sr/La>25, low Ce/Pb, Nb/U) compatible with contamination by arc/slab-derived and/or crustal components. We propose that the genesis and extrusion of magmas is related to the opening of two slab windows due to the subduction of two active ridge segments beneath Patagonia during Eocene and Mio-Pliocene.

Aspects that show the homogeneity or heterogeneity of these reforms in the region, as well as local specificities that block out the concretization of the reform are underlined. It is shown that the historicity that characterizes the educational reform has taken, in each country, a form that can be called, in Mexico, "conservative rupture"; in Chile, "conservative continuity"; in Brazil, "conservative renovation"; and, in Argentina, "interrupted rupture". Some conclusions about the impact of educational reform in the selected countries are recuperated through the analysis of 186 academic texts on the subject.

    Full Text Available Tomando como base documental el semanario Aurora de Chile, se realiza un análisis lingüístico que describe las caracterizaciones léxicas acomodadas a los nuevos contextos sociolingüísticos en esta época histórica de la independencia colonial y los fenómenos gramaticales que permiten observar rasgos diferenciadores en la lengua que se asienta en esta sociedad chilena. Por una parte, resulta interesante constatar la variación léxica que este texto periodístico, portavoz de una ideología ilustrada, proporciona para alcanzar un mejor conocimiento del grado de penetración del nuevo léxico político-social, con voces en muchos casos recreadas con las acepciones dominantes en las comunidades insurgentes. Por otra, la descripción de los fenómenos gramaticales y del léxico general de este corpus aporta datos concretos acerca de la preferencia de estas variantes lingüísticas y del grado de estandarización que van adquiriendo, como usos emergentes de la lengua española en Chile, bien como asentamientos de estructuras sintácticas y de léxico tradicionales o bien como mecanismos innovadores en la gramática y en el vocabulario diferencial americano.Based on the weekly newspaper Aurora de Chile, a linguistic analysis is here introduced including both the description of lexical characterizations as they adapted to the new sociolinguistic contexts in the historical period of the colonial emancipation and the grammatical phenomena that allow for the observation of differentiating features of the language being established in the Chilean society of the time. On the one hand, it is of interest to observe the lexical variation displayed in this journalistic text, which represents an illustrated ideology, in order to better understand the degree of penetration of the new political and social vocabulary, with voices in many cases recreated with uses dominating the insurgent communities. On the other hand, the description of the grammatical

    In marine benthic ecosystems, larval connectivity is a major process influencing the maintenance and distribution of invertebrate populations. Larval connectivity is a complex process to study as it is determined by several interacting factors. Here we use an individual-based, biophysical model, to disentangle the effects of such factors, namely larval vertical migration, larval growth, larval mortality, adults fecundity, and habitat availability, for the marine gastropod Concholepas concholepas (loco) in Chile. Lower transport success and higher dispersal distances are observed including larval vertical migration in the model. We find an overall decrease in larval transport success to settlement areas from northern to southern Chile. This spatial gradient results from the combination of current direction and intensity, seawater temperature, and available habitat. From our simulated connectivity patterns we then identify subpopulations of loco along the Chilean coast, which could serve as a basis for spatial management of this resource in the future.

    Full Text Available Between November 2001 and December 2002, 600 dog fecal samples were collected in main squares and public parks of 13 cities in Chile, from the extreme north to the extreme south of the country. The samples were processed in the laboratory by centrifugal sedimentation and the Harada-Mori methods. T. canis eggs were found in 12 cities. Detection rates ranged from 1.9 to 12.5% with an average of 5.2%. Seven percent of the samples had eggs and 9.5% had rhabditoid and/or filariform larvae of Ancylostomatidae. Strongyloides stercoralis were not found. Squares and public parks in Chile pose a potential risk of exposure to visceral, ocular, and/or cutaneous larva migrans syndromes.

    Medical journals published in non-English languages face a handicap: their worldwide readership and citation are reduced in comparison to journals published in English. This handicap is worse for small journals edited in developing countries, regardless of whether they publish original research articles including abstracts in English. To facilitate the international diffusion of selected Chilean scientific journals, the "Comisión Nacional de Investigación Científica y Tecnológica" enforced the program "SciELO Chile" with a web site in Internet (www.scielo.cl) including the full text of articles published in recent issues. Revista Médica de Chile is the first Chilean medical journal that appears in this web site, sponsored by the National Library of Medicine, Washington D.C. We expect that this web site will give a favorable input to authors of articles published in our journal. PMID:11351462

  11. Mental disability and active citizenship: The challenge of a new legislation of mental health for Chile

    Full Text Available Nowadays, the disability approach is a perspective that proposes a way to deal with the incorporation of social dimension in mental health understanding. Its hegemony in Chile turns visible considering the design of mental health laws and public policies over the past 20 years. However, this approach to mental health as well as the legislations and policies developed and related to it, hardly take over the situation of justice and citizenship of this group of people. These difficulties are particularly relevant when the exercise of active citizenship is required, since citizenship has been proved to show a therapeutic effect on the deficiencies or mental disorders. The urgent need of a mental health law for Chile demands the challenge of designing a law which recognizes the particularities of mental disability, but it also offers the historical possibility to effectively include the perspective of people with mental disabilities and their families in the discussion for a new law.

    Three Chilean women's rights organizations and CRLP presented a Shadow Report to the UN Committee on the Elimination of All Forms of Discrimination Against Women (CEDAW). The 25-page Shadow Report indicates in summary the disappointment of the Chilean women in their government. Although Chile has emerged from its history of military dictatorship and is taking its first steps toward returning to a democratic-style of government, the military and the Catholic Church still exert a very strong influence, especially when it comes to policy making. Chilean people especially women, continue to be tyrannized by repressive attitudes, laws, and policies. This tyrannization is exemplified by the rampant discrimination against women in the prisons and the punishment of those undergoing illegal abortions. In short, women have no rights in Chile, and the government has not done enough to eliminate discrimination against them. PMID:12346531

  13. An inverted double seismic zone in chile: evidence of phase transformation in the subducted slab.

    Comte, D; Suárez, G

    1994-01-14

    Data from two microseismic field experiments in northern Chile revealed an elongated cluster of earthquakes in the subducted Nazca plate at a depth of about 100 kilometers in which down-dip tensional events were consistently shallower than a family of compressional earthquakes. This double seismic zone shows a distribution of stresses of opposite polarity relative to that observed in other double seismic zones in the world. The distribution of stresses in northern Chile supports the notion that at depths of between 90 to 150 kilometers, the basalt to eclogite transformation of the subducting oceanic crust induces tensional deformation in the upper part of the subducted slab and compressional deformation in the underlying mantle.

    The Atacama Desert (Chile), one of the most arid places on Earth, shows hostile conditions for the development of epilithic microbial communities. In this study, we report the association of cyanobacteria ( Chroococcidiopsis sp.) and bacteria belonging to Actinobacteria and Beta-Gammaproteobacteria and Firmicutes phyla inhabiting the near surface of salt (halite) deposits of the Salar Grande Basin, Atacama Desert (Chile). The halite deposits were investigated by using optical, confocal and field emission scanning electron microscopes, whereas culture-independent molecular techniques, 16S rDNA clone library, alongside RFLP analysis and 16S rRNA gene sequencing were applied to investigate the bacterial diversity. These microbial communities are an example of life that has adapted to extreme environmental conditions caused by dryness, high irradiation, and metal concentrations. Their adaptation is, therefore, important in the investigation of the environmental conditions that might be expected for life outside of Earth.

    The earthquake nucleation process has been vigorously investigated based on geophysical observations, laboratory experiments, and theoretical studies; however, a general consensus has yet to be achieved. Here, we studied nucleation process for the 2014 Iquique, Chile Mw 8.2 megathrust earthquake located within the current North Chile seismic gap, by analyzing a long-term earthquake catalog constructed from a cross-correlation detector using continuous seismic data. Accelerations in seismicity, the amount of aseismic slip inferred from repeating earthquakes, and the background seismicity, accompanied by an increasing frequency of earthquake migrations, started around 270 days before the mainshock at locations up-dip of the largest coseismic slip patch. These signals indicate that repetitive sequences of fast and slow slip took place on the plate interface at a transition zone between fully locked and creeping portions. We interpret that these different sliding modes interacted with each other and promoted accelerated unlocking of the plate interface during the nucleation phase.

    Full Text Available Over the last 20 years, demand for air passenger transport has grown dramatically. At the same time, the two largest domestic airlines merged and several smaller entrants exited without being able to make significant inroads. As a result, the industry is highly concentrated, with a dominant firm and a few fringe firms. This condition has generated considerable public debate about the degree of competition in the airline industry in Chile. With the purpose of contributing to the public discussion, this paper analyzes the industry from an industrial organization point of view. Specifically, the paper describes the domestic airline industry in Chile, defines the relevant market and then analyzes both the degree of concentration and entry conditions. In particular, I focus on the roles played by vertical integration, the computer reservation systems and the revenue management practice. I then evaluate self-regulation of airfares by the dominant firm and propose several public policies to increase competition.

    The study of neighborhood characteristics and their effects on individuals has become an area of increasing attention by scholars from various disciplines in developed countries. Although there are various methods to study neighborhoods and their impact on human populations, one of the most used is the Systematic Social Observation -Observación Sistemática de Vecindarios (OSV), in Spanish-because it allows the collection of information about various features of the physical, social, environmental and economic characteristics of neighborhoods. The purpose of this article is to (i) briefly present some research on neighborhood effects influential in the U.S., ii) describe how they Systematic Social Observation was designed and implemented in the city of Santiago, Chile, iii) discuss some facilitators and obstacles of the implementation process and, finally iv) list possible contributions and limitations this approach would offer the profession of social work in Chile.
