    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

  4. Towards Behavioral Reflexion Models

    2009-01-01

    Software architecture has become essential in the struggle to manage today s increasingly large and complex systems. Software architecture views are created to capture important system characteristics on an abstract and, thus, comprehensible level. As the system is implemented and later maintained, it often deviates from the original design specification. Such deviations can have implication for the quality of the system, such as reliability, security, and maintainability. Software architecture compliance checking approaches, such as the reflexion model technique, have been proposed to address this issue by comparing the implementation to a model of the systems architecture design. However, architecture compliance checking approaches focus solely on structural characteristics and ignore behavioral conformance. This is especially an issue in Systems-of- Systems. Systems-of-Systems (SoS) are decompositions of large systems, into smaller systems for the sake of flexibility. Deviations of the implementation to its behavioral design often reduce the reliability of the entire SoS. An approach is needed that supports the reasoning about behavioral conformance on architecture level. In order to address this issue, we have developed an approach for comparing the implementation of a SoS to an architecture model of its behavioral design. The approach follows the idea of reflexion models and adopts it to support the compliance checking of behaviors. In this paper, we focus on sequencing properties as they play an important role in many SoS. Sequencing deviations potentially have a severe impact on the SoS correctness and qualities. The desired behavioral specification is defined in UML sequence diagram notation and behaviors are extracted from the SoS implementation. The behaviors are then mapped to the model of the desired behavior and the two are compared. Finally, a reflexion model is constructed that shows the deviations between behavioral design and implementation. This

    Vladimir Lefebvre’s Algebraic Model of Self-Reflexion is a formal and flexible system for modeling the processes that underlie human judgments. The model has received notable empirical support from studies within personal construct psychology using the repertory grid approach. In this chapter we briefly review this research and the repertory grid method, and then report the results of two new studies on the model conducted in our laboratory. Lastly, we will briefly discuss the implications of our findings with regard to future research on self-reflexion.

    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

    After 15 years of development of Hospital Medicine in Chile, there are several benefits of this discipline. Among others, a reduction in the length of hospital stay, readmissions, costs, and improved medical teaching of students, residents and fellows have been observed. However, in South América there are only isolated groups dedicated to Hospital Medicine in Chile, Argentina and Brazil, with a rather slow growth. The unjustified fear of competition from sub specialists, and the fee for service system of payment in our environment may be important factors to understand this phenomenon. The aging of the population makes imperative to improve the safety of our patients and to optimize processes and resources within the hospital, to avoid squandering healthcare resources. The following is a detailed and evidence-based article, on how hospital medicine might benefit both the public and prívate healthcare systems in Chile. PMID:23900327

    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.

    An analysis of health research in Chile is made, considering factors like exaggerated professional training during undergraduate studies and clinical residencies, and displacement of professionals from academic activities to more remunerative positions. Additionally, the limited role of the Ministry of Health in research promotion, evidenced by the almost absent participation of public hospitals in clinical research is discussed. Research investment, among a 0.6 to 0.8% of the GNP, is far from developed countries and Chile has not defined relevant health problems where a search effort would have an impact in public health. The marked centralism of the country attempts against regional application to financed projects. The following suggestions are made: to increase the financing for investigation, to reassign resources allowing the access of regional institutions, to financing, to discuss in the Chilean Association of Medical Faculties (ASOFAMECH) the creation of an academic degree by means of a thesis during the professional studies and to give facilities to develop research during clinical residencies. Also, the Ministry of Health should be involved, creating a national agenda or research priorities and increasing its association with Universities. Also training programs for professionals with a special interest in investigation should be devised. PMID:11227251

    Mental disorders are among the most prevalent of chronic disorders, and a high prevalence of these disorders has been consistently found in jails and prisons. This study was a retrospective case series that described the population of adults charged with a criminal offense who were court ordered to undergo a psychiatric assessment within the Medical Legal Service in Santiago, Chile from 2005 to 2006. Characteristics were explored in order to better understand this population in light of the recent reforms in the judicial and health systems of Chile. Ninety percent of sampled individuals were male, primarily between the ages of 18-39 years. Seventy percent of the evaluations came from the pre-reformed judicial system and 30% were from the reformed system. Approximately 63% of evaluated offenders were considered to have a psychiatric pathology, the most common being the personality disorders. Of the evaluated offenders, approximately 84% were considered by a psychiatrist to be criminally responsible for their crime, 7% were regarded as having diminished criminal responsibility, 4% were considered to be not criminally responsible for their crime, and 4% were cases where criminal responsibility was not applicable. Profession status, municipality of residence, type of residence, ICD-10 diagnosis, treatment recommendation, and criminal responsibility were found to be significantly different between male and female evaluated offenders. Results from this investigation will contribute to knowledge about forensic psychiatry and mental health in Latin America, and will hopefully pave the way for more research and international comparisons.

    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

    This ASTER image covers 30 by 37 km in the Atacama Desert, Chile and was acquired on April 23, 2000. The Escondida Cu-Au-Ag open-pit mine is at an elevation of 3050 m, and came on stream in 1990. Current capacity is 127,000 tons/day of ore; in 1999 production totaled 827,000 tons of copper, 150,000 ounces of gold and 3.53 million ounces of silver. Primary concentration of the ore is done on-site; the concentrate is then sent to the coast for further processing through a 170 km long, 9 pipe. Escondida is related geologically to three porphyry bodies intruded along the Chilean West Fissure Fault System. A high grade supergene cap overlies primary sulfide ore. This image is a conventional 3-2-1 RGB composite. Figure 1 displays SWIR bands 4-6-8 in RGB, and highlights lithologic and alteration differences of surface units. The image is located at 24.3 degrees south latitude and 69.1 degrees west longitude.

    Erosion and sediment transport in arid environments is thought to depend on the frequency of large floods as well as on mean precipitation rate and slope, but their relative impact remains a matter of active debate. The Chilean Andes are elongated along a sharp precipitation rate gradient, offering the possibility to rank these factors over different time spans. We compare suspended load measurements-derived decennial erosion rates and 10Be-derived millennial erosion rates along this gradient. Both parameters follow the same latitudinal trend and peak where the climate is Mediterranean (mean runoff ~0.55 m/m), confirming that slope is the main factor even along this contrasted climate. The comparison of these erosion rates documents the progressive contribution of rare and strong climatic events on the millennial erosion from humid to arid catchments. In the wetter BíoBio catchment, the separation of suspended sediment yield during base and direct flows shows that the dynamics of groundwater circulation controls most of the sediment hysteresis at gauging stations at annual scale. In addition, the mega El Maule earthquake (Mw8.8 in 2010), in front of humid to semi-arid catchments, has not increased the suspended sediment concentration in rivers, excepted in the steepest and driest catchments. Over millennial scales, preliminary 10Be concentrations in individual gravels and cobbles suggest mean river transport rates of several m/yr in an arid canyon of north Chile.

    The Expedition 3 crew of the International Space Station caught a rare glimpse of the massive ice fields and glaciers of Patagonia early in the afternoon on September 25, 2001. This part of the South American coast sees frequent storms and is often obscured from view by cloud cover. Bruggen Glacier in southern Chile is the largest western outflow from the Southern Patagonian Ice Field and, unlike most glaciers worldwide, advanced significantly since 1945. From 1945 to 1976, Bruggen surged 5 km across the Eyre Fjord, reaching the western shore by 1962 and cutting off Lake Greve from the sea. The glacier continued advancing both northward and southward in the fjord to near its present position before stabilizing. The growth covers a distance of more than 10 km north to south, adding nearly 60 square km of ice. Additional information on this and other Patagonian glaciers may be found at the following link: USGS - Historic Fluctuations of Outlet Glaciers from the Patagonian Ice Fields.

    Servicio Paz y Justicia (SERPAJ) is a nongovernmental organization (NGO) established in Chile in 1977. It supports fundamental human dignity and rights by fighting discrimination and exclusion based upon individual differences. SERPAJ promotes training, organization, and the political participation of community members as part of the democratic process, working mainly with the at risk women, street children, and youth of Santiago's working-class neighborhoods. Groups participate in workshops and training courses on human rights and development, civic education, and methods of non-violent community action. In 1987, SERPAJ-Sur Oriente began to include the topic of sexuality and AIDS/STDs in courses training working-class women as community human rights agents. The NGO is therefore one of the first mainstream Chilean human rights organizations to incorporate HIV/AIDS issues. A basic facts brochure was developed, followed by a pilot education project developed in one neighborhood which was then systematically replicated in other neighborhoods. The comments of some people who have participated in SERPAJ workshops are presented. PMID:12347181

    A group of 19 health professionals implicated in supportive care wanted to suggest some reflexions for organization, setting and evaluation of the supportive care in institutions and health territories. The suggested organization must be applicable to any cancer patient and the place of the care whatever the age, the stage of the disease; in the future, must be applicable to any patient with serious chronic illness. This organization must allow to optimize the accompaniment and the care of the patients and their close relations by 1) precise and regular analysis of their needs; 2) the respect of the continuity of the health care; 3) the setting of collaborative practice and transversality in the care. It is not a new medical speciality but a coordination of competences for patients and their families. PMID:19903599

    In Chile there are six established medical schools at public (Chile, Valparaiso and Temuco) or private (Catholic, Concepción and Austral) universities created between 1833 and 1971. Since 1990, three new medical schools (two private) were created and a fourth is projected, concerning the chilean medical corps. We present three position articles on the subject written by Dean Pedro Rosso, from the Catholic University, Dr Pedro Castillo, Chief of Human Resources of the Ministry of Health and Dean Alejandro Goic from the University of Chile. Dean Rosso emphasizes the need to have assessment procedures that guarantee quality standards in the new medical schools. Dr Castillo attracts attention on preserving the compromise with the society, inherent to chilean medicine. Dean Goic analyzes systematically the reasons to prevent the proliferation of medical schools in the country, maintaining an equilibrium between freedom of teaching and public faith protection.

    A January 6, 2002 ASTER nighttime thermal infrared image of Chiliques volcano in Chile shows a hot spot in the summit crater and several others along the upper flanks of the edifice, indicating new volcanic activity. Examination of an earlier nighttime thermal infrared image from May 24,2000 showed no thermal anomaly. Chiliques volcano was previously thought to be dormant. Rising to an elevation of 5778 m, Chiliques is a simple stratovolcano with a 500-m-diameter circular summit crater. This mountain is one of the most important high altitude ceremonial centers of the Incas. It is rarely visited due to its difficult accessibility. Climbing to the summit along Inca trails, numerous ruins are encountered; at the summit there are a series of constructions used for rituals. There is a beautiful lagoon in the crater that is almost always frozen.

    The daytime image was acquired on November 19, 2000 and was created by displaying ASTER bands 1,2 and 3 in blue, green and red. The nighttime image was acquired January 6, 2002, and is a color-coded display of a single thermal infrared band. The hottest areas are white, and colder areas are darker shades of red. Both images cover an area of 7.5 x 7.5 km, and are centered at 23.6 degrees south latitude, 67.6 degrees west longitude.

    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

    [Joint Press Release by the Government of the Republic of Chile and the European Southern Observatory. The text is issued simultaneously in Santiago de Chile (in Spanish) and at the ESO Headquarters in Garching (in English).] Today, Tuesday, 18 April 1995, at the ESO Headquarters in Garching (Germany), Mr. Roberto Cifuentes, Plenipotentiary Ambassador representing the Government of the Republic of Chile, and the Director General of the European Southern Observatory, Professor Riccardo Giacconi, have signed a Supplementary, Interpretative and Amending Agreement to the Convention of 6 November 1963 which governs the relations between Chile and this International Organisation. This Agreement which in practice signifies a widening and strengthening of the cooperative relations between the Organisation and the Chilean scientific community will hereafter be submitted for ratification by the National Congress of the Republic of Chile (the Parliament) and by the ESO Council. According to the Agreement signed today, Chilean astronomers will have privileged access within up to 10 percent observing time on all present and future ESO telescopes in Chile. Moreover, ESO accepts to incorporate into its labour regulations for Chilean personnel concepts like freedom of association and collective bargaining. This signing of the Supplementary, Interpretative and Amending Agreement to the original Convention of 1963 follows after months of constructive dialogue between the parties. It constitutes an important step towards a solution of some of the pending points on the current agenda for discussions between the Government of Chile and ESO. Among the issues still pending, ESO has informed the Government of Chile that respect for its immunities by the Chilean State is of vital importance for the continuation of the construction of the world's largest telescope at Paranal, as well as the continued presence of the Organisation in Chile.

    The flow properties of a low-pressure weakly ionized supersonic argon plasma jet are examined using Fabry-Pérot interferometry and laser induced fluorescence spectroscopy. The flow velocity and equilibrium temperature measured at the torch nozzle exit are in close agreement with computational fluid dynamics calculations. The model also predicts the plasma flow to be in a rarefied regime. Departure from thermal equilibrium is indeed observed behind the nozzle where the parallel temperature differs significantly from the perpendicular temperature. The development of the axial velocity component along the jet center stream line reveals the occurrence of the shock wave regular reflexion phenomenon: No Mach disk is formed and the flow experiences successive supersonic-to-supersonic transitions before reaching a subsonic regime. Shock wave regular reflexion is in fact favored under our experimental conditions since the speed ratio is high and the rarefaction degree is pronounced at the nozzle exit.

    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.

    Chile recently began a major rural electrification program to electrify those 240,000 families (about half of the rural people) who lack electricity access. In this paper, we discuss a pilot project to electrify three remote villages in Chile`s Region IX using wind/genset/battery hybrids. The intent of this project is to demonstrate the reliability and cost-effectiveness of wind/genset/battery hybrids and to encourage replication of these types of systems in Chile`s electrification program. For each village, electricity connections are planned for several residences, and also schools, health posts, community centers, or chapels. Projected average daily loads are small, ranging from 4 to 10 kWh. Using the optimization program HOMER and the simulation program Hybrid2, we evaluated options to maximize technical performance, minimize costs, and gain experience with a variety of systems and components. We find that wind/genset/battery hybrids will be able to provide cost-effective, reliable power for these sites. More importantly, their inherent flexibility allows for variations in load and resource without greatly affecting the cost of energy.

    The following ideas are widely accepted in Chile with respect to scientific activity: is carried out mainly in universities and science is considered a naturally university activity, that was developed in a period of more than 150 years by isolated individual efforts, c) it was transformed into an institutionalized activity at the universities after the university reform movement at the end of the 1960 decade, d) the activity is finally institutionalized in the country with the creation of the “Comisión Nacional de Investigatión Científica y Tecnológica, CONICYT (National Commission for Scientific and Technological Research) in 1967. This work presents preliminary findings showing that there are other institutional initiatives, different to the efforts from universities and directly dependent of the Chilean Government, in order to produce science and technology in Chile. This governmental initiatives start at the beginning of the Republic of Chile circa of 1810.

    One hundred and five rabies isolates obtained from domestic animals and insectivorous bats in Chile between 1977 and 1998 were molecularly characterized by limited sequence analysis of their nucleoprotein genes. These isolates were compared with viruses isolated from known domestic and wildlife rabies reservoirs in the Americas to identify potential reservoirs of rabies in Chile. The phylogenetic analyses showed that none of the Chilean isolates segregated with viruses from the terrestrial reservoirs. No non-rabies lyssaviruses were found in this study. The Chilean samples were not related to viruses of the sylvatic cycle maintained by the common vampire bat (Desmodus rotundus) in Latin America. Five genetic variants were identified from insectivorous bats in Chile. The Brazilian free-tailed bat (Tadarida brasiliensis) was identified as the reservoir for the rabies genetic variant most frequently isolated in the country between 1977 and 1998. The close association of a group of viruses obtained from a domestic dog (Canis familiaris), Brazilian free-tailed bats, and a red bat (Lasiurus borealis) with viruses maintained by Lasiurus spp. in North America implicated species of this genus as the possible reservoirs of this particular genetic variant in Chile. Reservoirs for the other three variants remain unknown. PMID:10813604

    Infrequent occurrence of giant events may help explain how the 1960 Chile earthquake attained M 9.5. Although old documents imply that this earthquake followed great earthquakes of 1575, 1737 and 1837, only three earthquakes of the past 1000 years produced geologic records like those for 1960. These earlier earthquakes include the 1575 event but not 1737 or 1837. Because the 1960 earthquake had nearly twice the seismic slip expected from plate convergence since 1837, much of the strain released in 1960 may have been accumulating since 1575. Geologic evidence for such incubation comes from new paleoseismic findings at the R¡o Maullin estuary, which indents the Pacific coast at 41.5§ S midway along the 1960 rupture. The 1960 earthquake lowered the area by 1.5 m, and the ensuing tsunami spread sand across lowland soils. The subsidence killed forests and changed pastures into sandy tidal flats. Guided by these 1960 analogs, we inferred tsunami and earthquake history from sand sheets, tree rings, and old maps. At Chuyaquen, 10 km upriver from the sea, we studied sand sheets in 31 backhoe pits on a geologic transect 1 km long. Each sheet overlies the buried soil of a former marsh or meadow. The sand sheet from 1960 extends the entire length of the transect. Three earlier sheets can be correlated at least half that far. The oldest one, probably a tsunami deposit, surrounds herbaceous plants that date to AD 990-1160. Next comes a sandy tidal-flat deposit dated by stratigraphic position to about 1000-1500. The penultimate sheet is a tsunami deposit younger than twigs from 1410-1630. It probably represents the 1575 earthquake, whose accounts of shaking, tsunami, and landslides rival those of 1960. In that case, the record excludes the 1737 and 1837 events. The 1737 and 1837 events also appear missing in tree-ring evidence from islands of Misquihue, 30 km upriver from the sea. Here the subsidence in 1960 admitted brackish tidal water that defoliated tens of thousands of

    Chile is one of the few countries that faces the environmental challenge posed by extensive arsenic pollution, which exists in the northern part of the country. Chile has worked through various options to appropriately address the environmental challenge of arsenic pollution of water and air. Because of cost and other reasons, copying standards used elsewhere in the world was not an option for Chile. Approximately 1.8 million people, representing about 12% of the total population of the country, live in arsenic-contaminated areas. In these regions, air, water, and soil are contaminated with arsenic from both natural and anthropogenic sources. For long periods, water consumed by the population contained arsenic levels that exceeded values recommended by the World Health Organization. Exposure to airborne arsenic also occurred near several large cities, as a consequence of both natural contamination and the intensive mining activity carried out in those areas. In rural areas, indigenous populations, who lack access to treated water, were also exposed to arsenic by consuming foods grown locally in arsenic-contaminated soils. Health effects in children and adults from arsenic exposure first appeared in the 1950s. Such effects included vascular, respiratory, and skin lesions from intake of high arsenic levels in drinking water. Methods to remove arsenic from water were evaluated, developed, and implemented that allowed significant reductions in exposure at a relatively low cost. Construction and operation of treatment plants to remove arsenic from water first began in the 1970s. Beginning in the 1990s, epidemiological studies showed that the rate of lung and bladder cancer in the arsenic-polluted area was considerably higher than mean cancer rates for the country. Cancer incidence was directly related to arsenic exposure. During the 1990s, international pressure and concern by Chile's Health Ministry prompted action to regulate arsenic emissions from copper smelters. A

    Diverse indicators were used to examine medical research in Chile. According to participation in Fondecyt projects, it was concluded that 420 persons were involved in medical sciences research and that 41.9% of them had no postgraduate title. During the eighties, there was a clear aging of the community dedicated to medical research. The scientific productivity was assessed through the inventory of publications in indexed journals. During the eighties, the number of articles in Clinical Medicine and Biomedical Sciences increased two-fold. The University of Chile published the greatest number of articles, followed by the Catholic University and, with a remarkable lower amount, other Universities. The impact of the published articles in Clinical Medicine and Biomedical Sciences was calculated from the citations that they generated from 1986 to 1988. Likewise, the articles registered in 1985 with the higher citation indexes were identified. PMID:8191125

    In the South American Republic of Chile genetic counseling is not currently recognized as an independent clinical discipline, and in general is provided by physicians with training in clinical genetics. At present only one genetic counselor and 28 clinical geneticists practice in this country of over 16 million inhabitants. Pediatric dysmorphology constitutes the primary area of practice in clinical genetics. Although the country has a universal health care system and an adequate level of health care, genetic conditions are not considered a health care priority and there is a lack of clinical and laboratory resources designated for clinical genetics services. Multiple educational, cultural and financial barriers exist to the growth and development of genetic counseling services in Chile. However, during the last 10 years increased awareness of the importance of identifying individuals at risk for inherited cancer syndromes led to growing interest in the practice of cancer genetics.

    This article explores Chilean attitudes toward the national population's size and rate of growth, as indicated by a special survey conducted for this purpose. The survey sample consisted of 1,410 men 20 to 54 years of age in urban Santiago, who were separated into six categories on the basis of their education and socioeconomic status. The subjects were interviewed by 36 students from the University of Chile who utilized a prepared questionnaire including both open-ended and multiple-choice questions. The results clearly indicate that men in the lower socioeconomic categories tended to know less about the population's size and growth than their better-off counterparts. Nevertheless, they more often felt that Chile had "too many" inhabitants, that recent population growth had been rapid, and that this rate of growth should be reduced. PMID:1212535

    Tuberculosis (TB) remains a major global and national problem. In Chile the incidence rate has remained at 13 per 100,000 inhabitants for several years without tendency to the expected decline that would allow their elimination by 2020. As a low prevalence country, TB cases have been concentrated in risk groups, reaching 33% in 2013, and this proportion increases as younger people are analyzed. The main risk groups in Chile are HIV co-infection, foreigners and population of prisons. By 2013, the proportion of cases for these three groups was 8.7%, 8.4% and 3.9% respectively, and these percentages vary significantly when regional situation is analyzed. In addition, many of these patients have more than one risk factor, demons-rating the existence of clusters more vulnerable to TB. PMID:25860037

    A retrospective epidemiological study about epidemiology of rabies in Chile between years 1989 and 2005 was done. A data base of 39793 national registries of rabies samples was analyzed by means of statistical packages. Out of 39793 analyzed cases, 719 bats, 7 dogs, 7 cats, 1 bovine and 1 human were positive to rabies throughout the 17 years of this study. The statistical analysis established a significant increase in the proportions of positivity in bats, with predominance of variant 4 between the reservoirs. Given the complexity of the wild cycle of the rabies in Chile, it is necessary to maintain a program control of rabies, directed to educate people for a responsible possession of domestic animals, due to the risk of rabies transmission from bat to the susceptible species.

    The availability and planning of Human Resources are important issues in many countries, as it is a key factor to cope with the critical challenges of Health Care Systems. In Chile, the Ministry of Health has undertaken several studies in order to improve knowledge about the medical workforce both in public and private sectors. The aim of this paper is to update and systematize the existing data on physicians and specialists availability in Chile. Several information sources were crossed to obtain new and more precise figures about this topic. According to the Internal Revenue System, 29.996 physicians practice medicine in the country, 43% of them hired in public services, part or full time. There is a high concentration of professionals in the central regions of Chile. Being the overall density of physicians of one per 559 inhabitants, the figures in the central region is one per 471 and one per more than 800 in the South and North. Between 2004 and 2008, the public sector increased its physician workforce by more than 80% in primary health care and more than 20% in the secondary and tertiary levels. This paper presents a method for a more rigorous identification of the categories of general practitioner and specialist respectively, and the results obtained from the databases used. PMID:22051705

    Neurocysticercosis (NCC) is not a notifiable disease in Chile and has received little attention on the national medical literature. In order to evaluate the relevance and clinical features of the disease, we performed a retrospective analysis in a general hospital of five cases of NCC during a 11 years period. Age ranged from 3 to 63 years and all had history of living or visiting southern Chile. Three patients had a solitary parenchymal cyst in vesicular or granulomatous stages and presented with generalized seizures. Their outcome was favorable after anticonvulsant and albendazole therapy and cysts reduced in size and calcified during follow-up. The other 2 patients had extra-parenchymal or mixed forms, including a pregnant woman with intraventricular cysts who developed endocraneal hypertension and recurrent dysfunction of her ventriculoperitoneal shunt. This patient died after discharge despite an initial favorable evolution with steroids and high-dose albendazole. This case series showed that NCC is still an epidemiological and clinical problem in Chile, affects patients within a wide range of age including children, requires multidisciplinary therapeutic interventions, and has two clinical presentations with different prognosis including one malignant form. To control this infection, a surveillance or reporting system should be initiated. PMID:22552515

    The present paper deals with iterative algorithms coupled with finite element methods (FEM) to solve the Radiative Transfer Equation (RTE) within semi-transparent heterogenous materials where specular reflexions occur on their boundaries. As our intention is to use such solution for inversion, the forward model should be solved as fastly as possible. This communication compares, in terms of both accuracy and CPU, the Discontinuous Galerkin (DG) method with the Streamline Upwind Petrov-Galerkin (SUPG) method, both being coupled with the Discrete Ordinate Method. Next, several iteratives methods used to accelerate the convergence are compared. These methods are the Gauss-Siedel (GS), the Source-Iteration (SI) and the Successive Over-Relaxation (SOR) methods.

    To identify those institutions granting medical research in Chile, every issue of Revista Médica de Chile published between 1987 and 1994 was reviewed, under the assumption that a vast majority (over 70%) of papers released by Chilean authors in topics of internal medicine and related subspecialties would have been submitted for publication in this journal. This assumption was based in the solid prestige of Revista Médica de Chile among Chilean physicians and investigators: it is one of the oldest medical journals in the world (founded in 1872) and its inclusion in the most important international indexes (e.g. Index Medicus, Current Contents) qualifies it in the "mainstream literature". Papers classified as "Original Articles", "Clinical Experiences", "Review Articles", "Public Health", "Case Reports", "Clinical Laboratory", "Special Articles" and "Medical Education" were screened for acknowledgment of financial support beyond the resources needed for routine clinical work. Among 1,528 manuscripts published, 344 were "Original Articles" and 61.3% of them acknowledged special financial support. Five hundred and one manuscripts were "Clinical Experiences" and 21.5% of them received special financial support; similar proportions were detected in "Review Articles" and "Public Health" topics. The institution ranked as providing support most often was the "Fondo Nacional de Ciencias y Tecnología" (FONDECYT), a governmental fund that assigns resources to research in all areas of science and technology through a peer-reviewed nationwide annual contest. FONDECYT was identified as provider of financial support to 45.2% of the "Original Articles" and "Clinical Experiences"; Chilean universities were mentioned by 33.6% and other entities (including pharmaceutical companies, other national and foreign organizations) by 23.1%.

    2015-01-01

    Chile is a country with an incipient HIV epidemic. Just as in other countries, disadvantaged groups in Chile are contributing to the increased incidence of the disease. The Mapuche indigenous population is one such group that has been affected by the spread of HIV. However, no prevention programs are tailored to the culturally specific needs of this community. In recognition of this discrepancy, an academic-community partnership was formed to develop an HIV educational module for a Mapuche community. The module was developed for use as part of an already established health-related program. The aims of the module were to identify perceptions about HIV among Mapuches and present information specific to HIV and its prevention. Focus was placed on cultural sensitivity. The module was carried out in connection with a first-aid course in an attempt to increase effectiveness of the intervention by working jointly with an established community program. Sixteen (16) Mapuches participated voluntarily and demonstrated some knowledge regarding HIV, but they lacked an overall understanding as to how it is transmitted and why prevention strategies are affective. Participants correctly identified sexual contact as a means of transmission, but when asked why, one person stated, “I just know it, I read it.” There were significant barriers to communication within the group, secondary to cultural practices related to age and gender. Major obstacles in controlling HIV are the lack of prevention strategies targeted to disadvantaged groups. The module developed for this intervention was the first effort of the Academic Community Partnership established between the Pontificia Universidad Católica de Chile and the Mapuche group around HIV prevention. Continued collaboration between academia and affected communities as well as incorporating HIV information into established programs are effective strategies for delivering prevention information to disadvantaged populations and for

  13. Rapid Characterization of Large Earthquakes in Chile

    Barrientos, S. E.; Team, C.

    2015-12-01

    Chile, along 3000 km of it 4200 km long coast, is regularly affected by very large earthquakes (up to magnitude 9.5) resulting from the convergence and subduction of the Nazca plate beneath the South American plate. These megathrust earthquakes exhibit long rupture regions reaching several hundreds of km with fault displacements of several tens of meters. Minimum delay characterization of these giant events to establish their rupture extent and slip distribution is of the utmost importance for rapid estimations of the shaking area and their corresponding tsunami-genic potential evaluation, particularly when there are only few minutes to warn the coastal population for immediate actions. The task of a rapid evaluation of large earthquakes is accomplished in Chile through a network of sensors being implemented by the National Seismological Center of the University of Chile. The network is mainly composed approximately by one hundred broad-band and strong motion instruments and 130 GNSS devices; all will be connected in real time. Forty units present an optional RTX capability, where satellite orbits and clock corrections are sent to the field device producing a 1-Hz stream at 4-cm level. Tests are being conducted to stream the real-time raw data to be later processed at the central facility. Hypocentral locations and magnitudes are estimated after few minutes by automatic processing software based on wave arrival; for magnitudes less than 7.0 the rapid estimation works within acceptable bounds. For larger events, we are currently developing automatic detectors and amplitude estimators of displacement coming out from the real time GNSS streams. This software has been tested for several cases showing that, for plate interface events, the minimum magnitude threshold detectability reaches values within 6.2 and 6.5 (1-2 cm coastal displacement), providing an excellent tool for earthquake early characterization from a tsunamigenic perspective.

    Studies about chondrocalcinosis in the Chiloe Islands (Chile) showed the high frequency of the disease there and how most of it is aggregated in a few highly involved families. Pedigrees and the high degree of consanguinity among parents of index cases pointed to a recessive inheritance. The presence of common Caucasian anthropological features of genetic value in the patients and the lack of Indian mixture in three of the involved families, documented back to 1600, suggest a Caucasian origin of the mutation. Biochemical studies of the patients' synovial fluid showed a significant rise in pyrophosphate concentration. Calcium, phosphorus, and alkaline phosphatase concentrations were not different from a control group. PMID:168817

    The Humboldt Current System, with its coastal upwelling ecosystem off Peru and Chile, is one of the most productive marine systems in the world. Here, significant exchange of heat and CO2 takes place between the ocean and the atmosphere due to upwelling of sub-surface, cold, nutrient-rich, CO2-saturated waters. In addition, the eastern South Pacific holds one of the three most important oxygen minimum zones of the global ocean. Through the biologically mediated process of denitrification, the oxygen minimum zone contributes to the global sink of nitrogen in the ocean and as a source of the greenhouse gas N2O to the atmosphere.

    Collections of mammals were made during more than three years of biological investigations in Chile sponsored by the Corporación Nacional Forestal under the aegis of the Peace Corps (Smithsonian Environmental Program). Genera and species hitherto unreported for that country were taken and many useful data concerning distributional patterns of other (mostly little-known) species were gathered. These collections have also proved valuable in better understanding Chilean mammals from a taxonomic point of view and contribute knowledge of the species' natural history. Specimens are to be deposited in the (United States) National Museum of Natural History (USNM) or are to be retained by the Corporación Nacional Forestal, Avda, Bulnes 285, Depto. 401, Santiago. Numbers provided below are field numbers. A final division of specimens between the two institutions has not yet been made. A number of specimens reported here were not taken by Peace Corps personnel but have been obtained by the National Museum of Natural History from other sources. Specimens in the Field Museum of Natural History (FMNH) were used in making comparisons. Some of Fulk's (GWF) specimens are at Texas Tech University. Other are at the Servicio Agricola y Ganadero in Santiago (as are specimens of some introduced species taken by Schamberger). Reise's (DF) are at the Universidad de Chile-Concepción and in his personal collection.

  1. The ecology of Chagas disease in Chile.

    PubMed

    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.

    The Government of Chile has placed a high priority on health promotion. This is evident in the advances made through its National Plan for Health Promotion (Plan Nacional de Promoción de la Salud) and the Vida Chile National Council for Health Promotion (Consejo Nacional para la Promoción de la Salud Vida Chile). Chaired by the minister of health, Vida Chile is made up of 28 public and private institutions from around the country. Vida Chile has a network of local councils that have been established in the country's comunas (communes, or local-level divisions of the country's provinces) and that include government officials and representatives of local societal and community organizations and private businesses. This report details the methods used to evaluate the National Plan as well as provides a preliminary assessment of the technical and financial results for the 1998-2006 period. Coverage indicators (number of participants; number of accredited health-promoting schools, workplaces, and universities; and number of health promotion events) and the extent of strategy implementation were used to measure the success of the program. Health promotion activities grew markedly during this period. Among the notable accomplishments were the following four: (1) 98% of the communes now have their own community health promotion plan and intersectoral Vida Chile committee to implement the plan, (2) there has been an increase in societal and community groups involved in the health promotion strategies, (3) 34% of the primary and secondary schools have become accredited health-promoting schools, and (4) approximately 20% of the total population benefited directly from community-health-plan activities in 2006. The average per capita cost of the community health plans' activities in 2006 was US$ 6.60. The two most important factors that facilitated the operation of the local health promotion plans were participation by community and societal groups and having an adequate

    The voucher model of financing schooling is becoming increasingly common throughout Latin America, with at least 12 countries using vouchers or voucher-like schemes. The present study focuses on the voucher models of Colombia and Chile, which have the most extensive programs of this type and those of the longest standing in the region. Using empirical evidence, the author compares the two models along four evaluative dimensions: educational quality, segregation, choice and socialization. After weighing the successes and weaknesses of each system, he concludes that, among other characteristics, the most effective and equitable voucher model features: (a) a flexible interpretation of educational quality; (b) financial grants which target solely the poor; (c) vouchers which cover the entire cost of tuition; (d) open enrolment at participating schools; (e) the participation of both secular and religious private schools; (f) accessible and meaningful information to parents; and (g) strong systems of accountability.

    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

    The first Chile-U.S. Astronomy Education Outreach Summit occurred March 22-28, 2015. The Summit was organized and supported by the U.S. Embassy in Chile, Associated Universities Inc., Association of Universities for Research in Astronomy, the Carnegie Institution for Science, the Image of Chile Foundation, the National Science Foundation, and La Comisión Nacional de Investigación Científica y Tecnológica. The Summit brought together a team of leading experts and officials from Chile and the U.S. to share best practices in astronomy education and outreach. In addition, Summit participants discussed enhancing existing partnerships, and building new collaborations between U.S. Observatories and astronomy education outreach leaders in Chile.The Summit was an exciting and intense week of work and travel. Discussions opened in Santiago on March 22 with a variety of astronomy education and public outreach work sessions, a public forum, and on March 23 the U.S. Embassy sponsored a Star Party. On Tuesday, March 24, the Summit moved to San Pedro de Atacama, where activities included work sessions, a visit to the Atacama Large Millimeter/Submillimeter Array telescope facilities, and a second public forum. From San Pedro, the team traveled to La Serena for additional work sessions, visits to Gemini and Cerro Tololo, a third public forum, and the closing session. At each stop, authorities and the broader community were invited to participate and provide valuable input on the current state, and the future, of astronomy education and public outreach.Following the Summit a core working committee has continued meeting to draft a “roadmap document” based on findings from the Summit. This document will help to identify potential gaps in astronomy outreach efforts, and how the U.S. facilities and Chilean institutions might work together strategically to address these needs. The first draft of this “roadmap document” will be made available for comment in both Spanish and

    Avian influenza (AI) was diagnosed in May 2002 for the first time in Chile and South America. The epidemic was caused by the highly pathogenic AI (HPAI) virus subtype H7N3 that emerged from a low pathogenic virus. The index farm was a broiler breeder, located in San Antonio, V Region, which at the time was a densely populated poultry area. Stamping of 465,000 breeders, in 27 sheds, was immediately conducted. Surveillance activities detected a second outbreak, 1 wk later, at a turkey breeding farm from the same company. The second farm was located 4 km from the index case. Only 25% of the sheds were infected, and 18,500 turkeys were destroyed. In both outbreaks, surveillance zones and across-country control measures were established: prediagnosis quarantine, depopulation, intensive surveillance, movement control, and increased biosecurity. Other measures included cleaning, disinfection, and controlling the farms with sentinels to detect the potential presence of the virus. Zoning procedures were implemented to allow the international trade of poultry products from unaffected areas. Positive serologic results to H5N2 virus also were detected in other poultry farms, but there was no evidence of clinical signs or virus isolation. Epidemiological investigation and laboratory confirmation determined that positive serology was related to a contaminated imported batch of vaccine against inclusion body hepatitis. All actions taken allowed the control of the epidemic, and within 7 mo, Chile was free of AI. Epidemic and control measures that prevented further spread are described in this article, which illustrates the importance of a combination of control measures during and after an outbreak of AI. This study is a good example of how veterinary services need to respond if their country is affected by HPAI. PMID:17494584

    The Paraonidae are a polychaete family of small body size which have not been reported for Chile until recently. Mainly due to improved sample-processing methods, research campaigns carried out in 1994 and 1996 on three areas off southern Chile have yielded numerous records. Several species proved to be new to the Chilean polychaete fauna, including species that have been known previously only from Antarctic areas. These new records and range extensions are reported in this paper.

Filtration coefficients (Lp) of the capillary wall were determined from measurements of fluid filtration rate at a series of different capillary pressures (Michel, Mason, Curry & Tooke, 1974). The osmotic reflexion coefficients (sigma) to albumin and myoglobin were determined by comparing the effective osmotic pressure exerted by these solutes across the capillary walls with their osmotic pressures in a membrane osmometer. 2. Lp and sigma to albumin were measured in eighteen vessels at different sites in the capillary bed with the tissue temperature in the range of 20-24 degrees C. Lp varied from 1.5 x 10(-3) to 15 x 10(-3) micrometer sec-1 cm H2O-1 having a higher mean value in nine venous capillaries (11.33 x 10(-3) micrometer sec-1 cm H2O-1) than in nine arterial and mid-capillaries (4.83 x 10(-3) micrometer sec-1 cm H2O-1). For all eighteen vessels sigma to albumin had a mean value of 0.816 (S.E. of mean +/- 0.027). There was no correlation between Lp and sigma. The mean value of sigma for the venous capillaries was 0.841 (S.E. of mean +/- 0.04) and the other nine vessels 0.802 (S.E. of mean +/- 0.034). 3. The osmotic reflexion coefficient to myoglobin was measured in seven different capillaries and found to have a mean value of 0.348 (S.E. of mean +/- 0.012) at 20-24 degrees C. The Lp of the capillaries varied from 3.0 x 10(-3) to 10.5 x 10(-3) micrometer sec-1 cm H2O-1. There was no correlation between sigma for myoglobin and Lp. 4. The method of Curry, Mason & Michel (1976) was used to measure sigma for urea in eight capillaries at 20-24 degrees C (sigma for albumin was also measured in two of these vessels). The mean value of sigma for urea was 0.061 (S.E. of mean +/- 0.012). The exclusive water channel (Curry et al. 1976) was calculated to have a value of 0.209 x 10(-3) micrometer sec-1 H2O

    1. The iridescent stripe of the freshwater teleost, the neon tetra, changes from green in the daytime to violet-blue at night. 2. Spectral reflectance measurements were used to follow these colour changes. 3. Light causes a shift in reflectance to longer wavelengths in living fish and in isolated tissue from the lateral stripe. The change is reversed in darkness. 4. The spectral reflectance shifts to longer wavelengths when the fish is disturbed in darkness. No such colour changes were seen in fishes kept alive in 10(-4) M-reserpine. 5. Hypotonic Ringer solution causes a reflectance shift to longer wavelengths and hypertonic solution causes a shift to shorter wavelengths. 6. The iridescent reflexions from the lateral stripe which is continued across the iris originate from iridophores in the dermis. These iridophores contain regular stacks of broad, double-sided hexagonal plates that are about 10 nm thick. Each plate is contained within a pouch in the cytoplasm and is separated from its neighbour by approximately one quarter the wavelength of light. 7. A distinction is drawn between the physiologically active iridophores in the lateral stripe and iris that have broad hexagonal crystal plates which are very thin and the physiologically inactive iridophores that are also found in the iris, but in addition are found on the flanks below the lateral stripe, and on the head. These iridophores contain hexagonal crystals that are usually narrower than the active type, but are about 60-100 nm thick. Images Plate 1 Plate 2 Plate 3 Plate 4 Plate 5 PMID:7108777

    Fast convergence between the oceanic Nazca and the continental South American plate is accommodated by recurrent rupture of large segments of the two plates' interface. The resulting earthquakes are among the largest and, for their sizes, most frequent on Earth. Along the Chilean and southern Peruvian margin, all 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 ~8.8 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 north and south broke rather recently in 1995 and 2001 in M>8 earthquakes and an M 7.7 earthquake encroached the southern part of the gap in 2007. The IPOC project intends to investigate this segment of the Nazca-South American plate boundary, on which a strong to devastating earthquake is expected to occur within the next years, by monitoring at a variety of time-scales deformation, seismicity, and magnetotelluric fields in the subduction zone at the closing stages of the interseismic cycle before and possibly during occurrence of a big earthquake. For that purpose, installation of long-term observatories in Northern Chile 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 (Paris, France), and the German Research Centre for Geosciences (GFZ, Potsdam, Germany). Currently we are operating 14 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. To cope with the high resolution and dynamic of the sensors and data acquisition

  16. Chile's dilemma: how to reinsert scientists trained abroad.

    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

    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

    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.

    It is commonly thought that the longer the time since last earthquake, the larger the next earthquake's slip will be. But this logical predictor of earthquake size, unsuccessful for large earthquakes on a strike-slip fault, fails also with the giant 1960 Chile earthquake of magnitude 9.5 (ref. 3). Although the time since the preceding earthquake spanned 123 years (refs 4, 5), the estimated slip in 1960, which occurred on a fault between the Nazca and South American tectonic plates, equalled 250-350 years' worth of the plate motion. Thus the average interval between such giant earthquakes on this fault should span several centuries. Here we present evidence that such long intervals were indeed typical of the last two millennia. We use buried soils and sand layers as records of tectonic subsidence and tsunami inundation at an estuary midway along the 1960 rupture. In these records, the 1960 earthquake ended a recurrence interval that had begun almost four centuries before, with an earthquake documented by Spanish conquistadors in 1575. Two later earthquakes, in 1737 and 1837, produced little if any subsidence or tsunami at the estuary and they therefore probably left the fault partly loaded with accumulated plate motion that the 1960 earthquake then expended. ?? 2005 Nature Publishing Group.

This reform guarantees coverage for a specific set of health conditions. Thus, the purpose of this study is to provide timely evidence for policy makers to understand the current distribution and equity of health care utilization in Chile.The authors analyzed secondary data from the National Socioeconomic Survey (CASEN) for the years 1992-2009 and the 2006 Satisfaction and Out-of-Pocket Payment Survey to assess equity in health care utilization using two different approaches. First, we used a two-part model to estimate factors associated with the utilization of health care. Second, we decomposed income-related inequalities in medical care use into contributions of need and non-need factors and estimated a horizontal inequity index.Findings of this empirical study include evidence of inequities in the Chilean health care system that are beneficial to the better-off. We also identified some key factors, including education and health care payment, which affect the utilization of health care services. Results of this study could help researchers and policy makers identify targets for improving equity in health care utilization and strengthening availability of health care services accordingly.

    Nonsyndromic cleft lip with or without cleft palate (CL/P) has an incidence of 1.5 per 1,000 live births in Chile, with 1.7 per 1,000 in males and 1.3 per 1,000 in females, which is nearly the same as the level found in Asian populations. The high rate of occurrence of CL/P in Chile is probably due to the presence of Amerindian genes in Chilean populations. Using the computer program PAP, a complex segregation analysis of CL/P was conducted for 67 multigeneration pedigrees from Chile, each ascertained from one affected proband. These pedigrees yielded 162 affected individuals and over 898 family members who were included in the analysis. The most parsimonious model of transmission indicated the presence of an autosomal dominant gene with reduced (20-25%) penetrance. PMID:9224940

    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.

    This study is an historical analysis of food consumption and nutrition in Chile emphasizing the influence of political and economic factors on nutritional standards. It attempts to document and explain the persistence of malnutrition as a widespread social problem in Chile even as the country achieved a relatively advanced state of economic development and boasted an unusually progressive record of social legislation. The major findings of the study were: (a) Chile's pattern of development, social reform efforts notwithstanding, consistently discriminated against low-income groups, and (b) this discrimination perpetuated low standards of nutrition and low levels of food consumption among the country's poor and undermined the effectiveness of specific measures to alleviate malnutrition.

    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 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

  13. Detailed Axial Morphology of the Chile Rise as it Approaches the Chile Triple Junction

    New bathymetric mapping along the two southernmost Chile Rise spreading segments shows axial volcanic structure that had not been evident in prior data. On the first segment extending north from the triple junction, where the basement is not obscured by sediment, a narrow line of volcanic structures appears to track the center of the rift valley. However, the next segment north, which is offset almost 50 km along a transform fault, has axial volcanic features that vary in position within the rift valley. In the northern ~half of this segment, lineated small volcanic structures hug the eastern scarp of the rift whereas in the south they are apparent only along the western part of the valley floor. A classic ridge-transform intersection (RTI) nodal deep occurs at this southern end of the segment. The position of the basin is asymmetric relative to the axis, toward the ‘inside corner’ on the eastern side of the rift valley. It is intriguing that the nodal deep, which is often modeled as the result of viscous mantle upwelling and plate stresses at an RTI, is centered on the opposite side of the rift valley from where the most recent volcanic activity occurred. Presumably this reflects interplay between local magma plumbing and tectonic stresses. In addition to the local ridge-transform forces, regional factors associated with subduction along the edge of the Cocos plate may affect mantle flow, melting, and detailed plate kinematics. We will present maps that combine the new Simrad EM122 swath sonar data, obtained during cruise MV1003 aboard R/V Melville, with pre-existing German and Chilean bathymetric grids. We will also discuss some of the tectonic and magmatic implications of the observed detailed morphologic patterns. As one of the few areas on the globe where active subduction and spreading occur in close proximity, the southernmost Chile rise presents a natural laboratory for studying the manifestations of interaction between these processes.

  14. Subduction zone guided waves in Northern Chile

    NASA Astrophysics Data System (ADS)

    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 (< 2 Hz) P-wave arrivals. Full waveform finite difference modelling is used to test the low velocity slab structure that cause this P-wave dispersion. The synthetic waveforms produced by these models are compared to the recorded waveforms. Spectrograms are used to compare the relative arrival 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

    An analysis was made over a period of 6 months of the incidents involving deliberate violence as registered in 'Vicaria', the clinic for out-patients within the Cathedral of Santiago de Chile. A total of 236 victims of deliberate violence were observed. Men aged 15-24 years were found to be victims of deliberate violence most frequently. 'Under education' was the most frequently registered occupation for both sexes, and a large group of male victims were 'Unemployed'. 82% of the victims were men and 14% women, 1.5% were boys and 1.5% girls less than or equal to 14 years of age. None of the victims were alcohol intoxicated when arriving in the clinic. The incidents took place in streets for 81% of the male victims and 79% of the female victims, and in the majority of the cases the aggressor(s) was one (or several) police officer(s). Six percent of the female victims had been injured at home. There was no reporting of the aggressor being a relative or acquaintance. The most frequent type of violence was blunt violence from baton(s) (44%), while blunt violence without the use of instruments was reported less frequently (33%). The use of firearms was registered in 18% of the cases, and of sharp instruments, combustion, electro-shock and chain in 1.4%, 1.4%, 1.1% and 0.4% of the cases respectively. A total of 517 primary and secondary diagnoses were applied to the patients. Most of the victims (99%) had moderate or less serious lesions according to the Abbreviated Injury Scale (AIS) (score less than or equal to 2). Twenty-four percent of the victims had more than 4 lesions, and 7% more than 10 lesions. The head/neck region and the trunk were affected with equal frequency, the frequency of injuries of the head/neck region being comparable with that observed among torture victims and in contrast to the pronounced predominance of injuries of the head/neck region observed in a Danish emergency ward study of deliberate violence.

  17. National Television of Chile--New headquarters building acoustic projects

    NASA Astrophysics Data System (ADS)

    Huaquin, Mario

    2002-11-01

    In the last 15 years TV stations in Chile have been incorporating in their facilities architectural acoustic and noise control approaches. This has been necessary as much for the technological advance, as for the necessity to achieve a better quality of sound that the listeners receive. 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. (To be presented in Spanish.)

    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.

    In February and March 2010 we conducted preliminary exploration for hydrothermal plume signals along the East Chile Rise where it intersects the continental margin at the Chile Triple Junction (CTJ). This work was conducted as one component of our larger NOAA-OE funded INSPIRE project (Investigation of South Pacific Reducing Environments) aboard RV Melville cruise MV 1003 (PI: Andrew Thurber, Scripps) with all shiptime funded through an award of the State of California to Andrew Thurber and his co-PI's. Additional support came from the Census of Marine Life (ChEss and CoMarge projects). At sea, we conducted a series of CTD-rosette and ABE autonomous underwater vehicle operations to prospect for and determine the nature of any seafloor venting at, or adjacent to, the point where the the East Chile Rise subducts beneath the continental margin. Evidence from in situ sensing (optical backscatter, Eh) and water column analyses of dissolved CH4, δ3He and TDFe/TDMn concentrations document the presence of two discrete sites of venting, one right at the triple junction and the other a further 10km along axis, north of the Triple Junction, but still within the southernmost segment of the East Chile Rise. From an intercomparison of the abundance of different chemical signals we can intercompare likely characteristics of these differet source sites and also differentiate between them and the high methane concentrations released from cold seep sites further north along the Chile Margin, both with the CTJ region and also at the Concepcion Methane Seep Area (CMSA). This multi-disciplinary and international collaboration - involving scientists from Chile, the USA, Europe and Japan - can serve as an excellent and exciting launchpoint for wide-ranging future investigations of the Chile Triple Junction area - the only place on Earth where an oceanic spreading center is being actively subducted beneath a continent and also the only place on Earth where all known forms of deep

    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

    1979-08-01

    Breastfeeding practices have greatly diminished in all industrialized countries in the past 30 years; only now breastfeeding is enjoying a revival, especially among better educated people, as data gathered in Sweden and in the U.S. show. In Chile, as in most underdeveloped countries, the practice of breastfeeding began declining in urban, then in rural areas, reaching the largest decline in 1930. Modernization and all the factors connected with it, and especially urbanization, are accountable for this change. To encourage breastfeeding in Chile several recommendations are possible, among which is the education of parents on the advantages of breastfeeding. Mass media and all communication channels should be used; 2) better alimentation, when necessary at government expenses, for pregnant and nursing mothers; 3) legislation regulating the advertisement and distribution of infant formulas; 4) information on the possible effects of oral contraception on lactation; and 5) new social legislation protecting pregnant and nursing mothers.

    Partial remains of a titanosaur sauropod collected in the Tolar Formation (Upper Cretaceous) at the Atacama Desert (Antofagasta Region), northern Chile, is described, and a new species, Atacamatitan chilensis gen. et sp. nov., is erected. The material consists mainly of dorsal and caudal vertebrae, part of a humerus and a femur. The presence of a titanosaur confirms the Cretaceous age for the outcrops of red sandstone of the Tolar Formation whose age was previously uncertain, ranging from the Upper Cretaceous to the Paleocene. The new specimen represents the most complete dinosaur reported for this region and one of the most complete titanosaur known from Chile and the pacific margin of South America so far. PMID:21437382

  6. Trust via disasters: the case of Chile's 2010 earthquake.

    PubMed

    Dussaillant, Francisca; Guzmán, Eugenio

    2014-10-01

    Chile has a long-standing history of natural disasters and, in particular, earthquakes. The latest big earthquake hit Chile on 27 February 2010 with a magnitude of 8.8 on the Richter scale. As an event that had a profound impact on significant portions of the population, the earthquake could theoretically have served to build trust by promoting new trust networks through the enhancement of distant family ties and the interaction between affected neighbours. This study offers an empirical analysis of this theory in the Chilean case. It finds that if initial social capital is very low (thus allowing for post-disaster looting and violence), then the impact of the trust-increasing effect is smaller. It also shows that the effect of the disaster was not transitory, but that it persisted and actually increased over time. PMID:25196338

    In Chile, dog rabies has been controlled and insectivorous bats have been identified as the main rabies reservoir. This study aimed to determine the rabies virus (RABV) variants circulating in the country between 2002 and 2008. A total of 612 RABV isolates were tested using a panel with eight monoclonal antibodies against the viral nucleoprotein (N-mAbs) for antigenic typing, and a product of 320-bp of the nucleoprotein gene was sequenced from 99 isolates. Typing of the isolates revealed six different antigenic variants but phylogenetic analysis identified four clusters associated with four different bat species. Tadarida brasiliensis bats were confirmed as the main reservoir. This methodology identified several independent rabies enzootics maintained by different species of insectivorous bats in Chile.

  8. New L Chondrites from Antofagasta, Chile

    NASA Astrophysics Data System (ADS)

    Martinez, R.; Zolensky, M.; Martinez de Los Rios, E.

    1992-07-01

    Desert regions can be productive meteorite recovery locations because of low humidity, minimal ground cover and, in favorable situations, high prevailing winds to deflate surfaces. For these reasons we have made reconnaissance searches of a particularly arid Atacama Desert tract between Antofagasta and Mejillones, Chile (approx. 23 degrees 15'S, 70 degrees 30'W). One of us (EMR) had previously collected new ordinary chondrites from this same area, which has been named Pampa (a), (b), (c), and (e). The Pampa de Agua Blanca (PAB) chondrite is also apparently from this same area. In our brief 1991 reconnaissance we found additional specimens of (a) and (c). All of these meteorites have been found as multiple stones, necessitating pairing studies. Consequently, we examined our finds (a, b, c, and e), borrowed specimens from the Field Museum (a, b, PAB) and Robert Haag (c), and have performed the first detailed studies of the Pampa meteorites. Here we summarize results of these studies. Shock levels refer to the classification developed by Stoffler et al. (1991). PAMPA (a): This weathered meteorite is represented by several partially fusion-crusted fragments with a combined mass of approximately 380 g. No distinct chondrules are evident in thin section, although some chondrule fragments are present; considerable recrystallization is evident and plagioclase (Ab(sub)80Or5-Ab(sub)83Or(sub)5) is present as clear grains. Diopside and hydroxylapatite are also present. Olivine (Fo(sub)75.0 mean, 0.4% mean deviation-PMD) exhibits no shock effects. We classify Pampa (a) as L6, shock level 1. PAMPA (b): This is a weathered meteorite represented by numerous individual stones with a combined weight of approximately 10 kg. We examined thin sections from four individual stones of (b). A few distinct barred chondrules are evident in thin section, along with numerous chondrule and aggregate fragments. Olivine (Fo(sub)74.8 mean, 0.9 PMD) exhibits undulatory extinction, planar fractures

  9. Weathering of Iron Meteorites from Monturaqui, Chile

    NASA Astrophysics Data System (ADS)

    Bender Koch, C.; Buchwald, V. F.

    1994-07-01

    Monturaqui is a meteorite crater, 370 m diameter, in the Andes Mountains, Chile. The impact apparently took place in upper tertiary or pleistocene, judging from the topography of the drainage gullies in the crater area [1]. The surface topography and the state of the corroded meteorite suggest, however, that the climate some time ago must have been more humid. Small fragments of severely corroded iron meteorites have been collected in the vicinity, 50-200 m from the crater rim. Fourteen fragments of iron shale have been examined in order to determine the corrosion products of an entirely disintegrated iron meteorite. Polished sections display some vugs and microporosities and are >99.9% oxidic. The non-oxidic parts are minute particles of taenite (38-42%wt. Ni), schreibersite, rabdite (42%wt. Ni, 0.13%wt. Co, 12.5%wt. P), and cohenite (microhardness 1100 +- 50). The overall morphology of the oxide shales, which sometimes are of breadcrust type, is that of a coarse octahedrite, probably of Group IA similar to the Canyon Diablo meteorite [2]. X-ray diffractometry on powder samples disclose goethite and maghemite, and occasionally peaks from lepidocrocite and reevesite were identified. Peaks from magnetite, akaganeite, and hematite were not identified. The mineralogy and oxidation state of Fe was also investigated by ^57Fe Mossbauer spectroscopy. Spectra of a representative powder sample were obtained between 16 and 350 K. No indication of purely Fe(II)-containing compounds was present. Based on the identification of a component due to octahedrally coordinated Fe in magnetite (a mixed Fe(II)- Fe(III) site) a maximum of approximately 5 relative % of Fe(II) can be estimated. Consequently the determination of Fe in oxides by microprobe is reported as Fe(III). The dominating components in the Mossbauer spectra are due to maghemite and goethite, the latter exhibiting a wide variation in crystallite size as evidenced from the observed variation in blocking temperatures

    This study analysed factors associated with unintended pregnancy among adolescent and young adult women in Santiago, Chile. Three variations of a behavioural model were developed. Logistic regression showed that the effect of sex education on unintended pregnancy works through the use of contraception. Other significant effects were found for variables reflecting socioeconomic status and a woman's acceptance of her sexuality. The results also suggested that labelling affects measurement of 'unintended' pregnancy. PMID:7983095

  12. Paleogene tectonics and forearc strike-slip faulting: southern Chile

    SciTech Connect

    Leslie, R.B.; Cande, S.C.

    1985-01-01

    Several lines of evidence suggest that highly oblique Nazca-South America convergence during the middle to late Paleogene resulted in the development of a dextral strike-slip fault landward of the Chile trench. The Linquine-Ofqui fault (LOF) is nearly 1000 km long and trends approximately N10/sup 0/E between 39/sup 0/S and 47/sup 0/S. It consists of several fault strands with the dominant strand represented by a mylonitic zone approximately 3 km wide. Preliminary field mapping (Herve, 1984) indicates seaward trending splay faults that can be projected offshore in the vicinity of two large embayments along the Chile margin. The Golfo de Guafo embayment occurs between 43/sup 0/S and 44/sup 0/S and is approx.40 km wide in the N-S direction. The Golfo de Penas embayment is approx.75 km wide in the N-S direction and occurs between 47/sup 0/S and 48/sup 0/S at the southern end of the LOF. The authors suggest that these embayments are a consequence of NE-SW extension due to movement on splay faults of the LOF system during the middle to late Paleogene. Convergence during this time was highly oblique. Movement decreased on the northern portion of the LOF prior to a decrease in movement on the southern end. Radiometric dates on rocks from the fault zone (Herve, 1984) provide constraints on the timing of movement along the fault.

    This report, prepared at the request of the Government of Chile under the auspices of the U. S. Agency for International Development (US AID), is based on a 2-month assignment (Oct. 22 to Dec. 31, 1969) of the author and outlines a program of water resources studies. The study program, if followed to its conclusion, will provide the basic hydrologic and hydrogeologic information and analysis essential for planning optimum future development and use of the water resources of the valley.

    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.

    Scientific productivity in Chile was studied examining a data bank constructed with the publications indexed by the Institute for Scientific Information during 1987 and 1988. The bank excludes meeting abstracts and contains the full title of the published paper, the list of authors, addresses, field, and the nature of collaboration between two or more institutions. The articles were classified in different fields and tabulated according to the institution from which they originated. Although biology remains to be the more productive subject (26.5%) followed by medical sciences (23.9%) and chemistry (12.3%), articles in mathematics and physics continued their increase as in previous years. Using the scientometric indicators published by Braun et al., the impact of the research originated in Chile in biology, physics and mathematics was compared to that attained in Argentina, Brazil, Mexico and Venezuela. The role of the chilean National Research Fund and the output of the financed research projects were also analyzed. The successful results obtained during the first years in which the National Research Fund has been involved in the support of the scientific activity in Chile, confirms the need to strengthen its budget, according to the goals stated in the National Plan for Science and Technology for Development.

  16. Arsenic exposure and its impact on health in Chile.

    2006-06-01

    The problem of arsenic in Chile was reviewed. In Chile, the population is exposed to arsenic naturally via drinking-water and by air pollution resulted from mining activities. The sources of arsenic were identified to estimate the exposure of population to arsenic through air, water, and food. Health effects, particularly early effects, observed in children and adults, such as vascular diseases (premature cardiac infarct), respiratory illnesses (bronchiectasis), and skin lesions have been described. Chronic effects, such as lung and bladder cancers, were reported 20 years after peak exposure and persisted 27 years after mitigation measures for removing arsenic from drinking surface water were initiated. Although the effects of arsenic are similar in different ethnic and cultural groups (e.g. Japanese, Chinese, Indian, Bangladeshi, American, and Taiwanese), variations could be explained by age at exposure, the dose received, smoking, and nutrition. Since health effects were observed at arsenic levels of 50 microg/L in drinking-water, it is advised that Chile follows the World Health Organization's recommendation of 10 microg/L. The Chilean experience in removal of arsenic suggests that it is feasible to reach this level using the conventional coagulation process. PMID:17195557

    In 1999, after 6 years of intense work wirh Chilean authoritie Eduardo Frei Ruiz-Tagle, the then President of Chile signed into law Supreme Decree 686, the environmentally-linked "Norma Luminica". This, in effect, required that lighting in the three astronomically-sensitive Regions of Northern Chile (II Paranal,Armazones III Las Campanas IV La Silla, Tololo, Pachon) be directed downwards instead of into the sky. Various grace periods up to a maximum of five years were specified for different types of lighting. Street lighting was due to be fully compliant by 1st October, 2005. 70% of the street lighting in these 3 Regions now meets specifications and work continues towards full compliance. More sophisticated draft legislation is under consideration with several Chilean national authorities. This may include international lighting norms, energy-saving caps and measures to address energy-saving, environmental and human-health issues. With vigilance, these measures are likely to extend the useful life of all existing and major planned observatories in Chile by several decades.

    Penicillin production in Chile was a pioneering development; however there is not much information to learn about it. The Chilean Institute for Bacteriology (Instituto Bacteriológico de Chile) produced penicillin between 1944 and 1973. The stage starting in 1953 is better known since there was an agreement with United Nations. Our research focused on building a story about production between 1944 and 1954 based on archival information and the national and international historic context. Our results place Chile amongst the pioneer countries in the successful industrialization of the drug. Our conclusions are that this was a proper industrial production as opposite to a pilot plant - a name commonly used to call the early factory. We explain the production plant trajectory by making relations between technological change and governance. Finally, we believe the later expansion of the plant, in the context of the agreement with the United Nations, took place under unpromising governance conditions, which called for passive innovation and technology management.

    The genetic variability of four predominantly Indian populations of southern Chile's archipelagos was examined by determining the frequencies of four mitochondrial DNA haplogroups that characterize the American Indian populations. Over 90% of the individuals analyzed presented Native American mtDNA haplogroups. By means of an unweighted group pair method with arithmetic mean (UPGMA) dendrogram, a principal component analysis (PCA) derived from a distance matrix of mtDNA, and the exact test of population differentiation, we are able to prove the existence of a North-South cline. The populations in the northern part of the archipelagos are genetically similar to the Huilliche tribe, while the groups from the South are most closely related to the Fueguino tribe from the extreme South of Chile, and secondarily to the Pehuenche and Mapuche, who are found to the North and East of Chiloé archipelago. These results are consistent with a colonization of the southern archipelagos from Tierra del Fuego. We evaluate the evolutionary relationships of the population of the Chiloé area to groups from other geographic areas of Chile, using analysis of molecular variance (AMOVA). Three Amerindian clusters are identified: one formed by the Aymará and Atacameño, a second by the Huilliche, and a third including the Mapuche, Pehuenche, and Fueguino tribes, and the population inhabiting the South of the Chiloé arcipelago. These groups exhibit a North-South gradient in the frequency of haplogroup B, confirmed by F(ST) tests. PMID:16323203

    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

    The Nazca-Antarctic plate boundary, the Chile spreading ridge, subducts beneath South America, forming the northward-migrating Chile Triple Junction (CTJ), now at ~46.5°S, where an actively spreading segment is currently in the Nazca trench. Ridge subduction is associated with diachronously developed variable structure and magmatism of overriding South America. To assess the effects of ridge subduction, we deployed a network of 39 broadband seismometers in southern Chile between 43 - 49°S and 71 - 76°W from Dec. 2004 - Feb. 2007, recording 102 earthquakes suitable for receiver function analyses, i.e., M > 5.9, of various backazimuths, and at epicentral distances of 30 - 90°. The network encompassed onland portions of the current triple junction and ridge subduction, areas to the south of the CTJ where ridge segments subducted during the last 6 m.y., and regions north of the CTJ not yet affected by ridge subduction, allowing the assessment of the effects of ridge subduction on crustal structure of overriding South America. We constructed 551 teleseismic receiver functions to estimate crustal thicknesses, H, and average compressional to shear wave velocity ratios, Vp/Vs = k, using the iterative time deconvolution method of Ligorria and Ammon (1999). H and k were calculated using the grid search method of Zhu and Kanamori (2000). Beneath stations closest to the trench, where the Nazca plate subducts, we found Moho depths between 28 and 55 km, thickening northward. At the locus of current ridge subduction, in the Taitao Pennisula, thinner crust ranges from 27 - 36 km. H is 36-38 km where the Antarctic plate subducts and the Chile ridge recently subducted. The direct effect of the subducting ridge on South America can be seen in H differences between forearc regions that have sustained ridge subduction versus those that have not. South American forearc crust above the subducted Nazca plate is as much as 28 km thicker than forearc crust recently affected by ridge

    La astronomía gamma, en el extremo de energías detectadas hasta el presente, se encuentra en desarrollo en muchas partes del mundo y proporciona resultados sorprendentes a medida que la tecnología avanza en el desarrollo de nuevos detectores. La técnica Cherenkov Atmosférica es la utilizada para la detección, mediante telescopios en tierra, del efecto secundario causado por la radiación gamma de muy altas energías (E ≈ TeV). Por medio de telescopios o arreglos de detectores y utilizando la técnica mencionada, se han podido detectar algunas fuentes puntuales de mucha importancia astrofísica como la Nebulosa del Cangrejo y la galaxia de núcleo activo Markarian 421. El sistema instalado en San Juan, en cooperación con el grupo de Radiación Gamma del Observatorio Whipple, está constituído por tres colectores de 1.5m que registran pulsos de luz generados por las cascadas de partículas producidas por rayos cósmicos de todo tipo al entrar en la atmósfera terrestre. El sistema opera por barrido en ascención recta de la fuente observada que, para esta etapa del experimento, es el Centro Galáctico. Esta fuente extensa es conocida como emisor gamma de energías inferiores al TeV y ha sido observada anteriormente en este rango de energía desde el hemisferio norte pero con elevaciones bajas, situación no óptima para este tipo de técnica. Se presentan los primeros resultados del análisis de los datos obtenidos observando la región del Centro Galáctico, luego de dos años de observaciones, así como una descripción de la técnica Cherenkov Atmosférica y del equipo utilizado en la experiencia.

    2010-01-01

    Abstract Objectives There are no published studies on physical dating violence in college students in Chile, and campuses across the country currently lack systematized programs to prevent or respond to this public health problem. This is the first study to examine prevalence and predictors of physical dating violence victimization with a sample of female college students in Chile. Methods A closed-ended questionnaire was administered to students enrolled in general education courses at a major public university. The prevalence of women's physical dating violence victimization was calculated, and generalized ordered logit models were used to estimate risk factors for such victimization (n = 441). Ancillary analyses examined associations of dating violence victimization with experiences of unwanted sexual contact and forced condom nonuse. Results Approximately 21% of subjects reported one or more incidents of physical dating violence not involving physical injury since age 14, and another 5% reported at least one incident resulting in physical injury during this time period. Risk factors identified in five sequential models were sexual abuse and witnessing of domestic violence in childhood, low parental education, residence away from the parental home, urban residence, and having had sexual intercourse. Maternal employment and religious participation had protective effects. Dating violence victimization was found to be significantly associated with experiences of unwanted sexual contact and forced condom nonuse. Conclusions The study findings show a high prevalence of physical dating violence, strong associations between several sociodemographic factors and dating violence, and links between dating violence and sexual/reproductive risk. Our results indicate a need to expand attention to this public health problem in Chile as well as other developing countries, where research and prevention/response initiatives have generally been similarly limited.

    In an effort to characterize the spatial variability of pesticides, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs) in the Chilean atmosphere, XAD-based passive air samplers (PAS) were deployed for 12 months (2006-2007) along three elevational gradients in Northern, Central and Southern Chile, for a total of 20 sampling sites, ranging in elevation from 10 to 4400 m and ranging over 26 degrees of latitude. Hexachlorobenzene (HCB) had largely uniform air concentrations with latitude and altitude, and is therefore used to derive sampler specific sampling rates, that account for differences in uptake kinetics due to environmental factors such as altitude and temperature. Levels of pesticides in the atmosphere of Chile are very low and only α- and γ-hexachlorocyclohexane, α-endosulfan and chlorothalonil were present in all of the samples. The concentrations of these four pesticides in air decreased from North to South, with much steeper gradients for chlorothalonil and endosulfan. Chlorothalonil levels were greatly elevated in air samplers deployed in urban locations. Endosulfan concentrations in air tend to increase with elevation. Since endosulfan is particularly susceptible to mountain cold-trapping, such gradients may reflect the re-volatilization of endosulfan that had been preferentially deposited at higher altitudes. Alternatively, increasing endosulfan concentrations with elevation could be the result of transport to higher altitude sites from the other side of Andes. Airshed analysis indeed indicates that air masses originating outside of Chile have a higher influence on the higher elevation sites, especially along the Northern transect. Concentrations of four-ring PAHs ranged from 0.3 to 1300 pg m -3, with higher levels in air samplers deployed in urban areas and close to roads. PCB concentrations were low (0.7-27 pg m -3), with slightly higher levels of volatile congeners in two urban sampling sites in Concepcion and Arica

    This piece provides an initial assessment of the First Citizen Consensus Conference, an event held in the city of Santiago, Chile, from 22-24 November 2003, on the subject of "The Management of My Medical Record." This conference was the first citizen consensus conference that has been held in Chile as well as the first such conference in Latin America. Consensus conferences were devised by the Danish Board of Technology in 1987 as a way to assess science and technology issues through discussions between experts and a panel of lay persons. At the end of a consensus conference, the lay persons express their opinions and recommendations in a consensus report that is directed at policymakers, decision-makers, and the public in general. The objective of a consensus conference is to bridge the gaps that routinely exist among the general public, experts, and elected officials. So far, the Danish Board of Technology has organized more than 20 of these conferences, using a methodology that has become established as a model. Taking into account the changes that have occurred in the relationship between science and society at large, the Pan American Health Organization has decided to support the holding of consensus conferences in Latin America and the Caribbean. The First Citizen Consensus Conference adapted the Danish methodology to conditions in Chile, and this piece assesses the modifications that were made. In addition, some 6 to 12 months after the conference, there will be an external evaluation of the outcomes and impact of the conference, especially in the communications media, public debate, decision-making, and perceptions of the persons who were involved. Despite the criticisms made in this piece and some shortcomings that are pointed out, the First Citizen Consensus Conference achieved all of its objectives and will serve as an excellent model for similar conferences in other countries of the Americas.

    With this issue, Revista Médica de Chile will have been published uninterruptedly, for 130 years. Formal medical education had an early development since Chile became independent from Spain (1817). The first Medical Sciences Course was organized in 1833 by the Irish physician William C Blest. The Santiago Medical Society was founded in 1869 and its journal-Revista Médica de Chile--in 1872. Its first director was Dr. German Schneider. Revista Medica is the oldest serial publication in South America and the second oldest in the Spanish speaking world. This is a remarkable fact for a comparatively young country. With the creation of the Medical Society and Revista Medica, a process of continuous medical education was started and they became a real Graduate School. The Journal has adopted the main changes in knowledge and technology. Some important milestones of its development, during the second half of the 20th century, were the definition of its objectives and structure, the incorporation of peer review of manuscripts (even with foreign reviewers) the adoption of international guidelines for publication, its incorporation into the main biomedical journal indexes, the modernization of its printing process, the making of a computer generated index of all papers published since 1872, its incorporation into a digital library in INTERNET and the active participation of its editors in the World Association of Medical Journal Editors. The success of the journal is influenced by the independence that the Medical Society has conferred to the editors (all outstanding University Professors), as well as to the characteristics of an educational campus "invisible and without tumult" (Ingelfinger).

    The continental margin off central Chile, from Valparaiso to Valdivia, encompassing an area of 100,000 km/sup 2/, has been the target of exploratory activity by Empresa Nacional del Petroleo since 1970. Exploratory drilling began in 1972. By August 1984, total exploratory efforts had resulted in drilling 14 offshore wells and acquiring 12,130 km of seismic reflection lines. A biogenic gas accumulation was discovered in the F well. Because these attempts to find oil were unsuccessful and because drilling costs have escalated, exploratory activities have been curtailed. Forearc basins off central Chile are characterized by low geothermal gradient and a sedimentary filling of Cretaceous and Tertiary strata. Tertiary sequences are characterized by low organic carbon content, immature humic-type organic matter, and a biogenic gas potential. Cretaceous sequences are characterized by higher organic carbon content, good reservoir rocks, and fair to good source rocks. The organic matter is sapropelic, with vitrinite and liptinites, and is favorable for oil and gas generation. Seismic and well data suggest that Mesozoic and Cenozoic sedimentary rock sequences filling the basins (more than 4000 m thick at the shelf edge) extend 40-70 km beyond the present shelf edge. Mesozoic rocks deposited on the slope may generate petroleum and gas that could migrate upslope and accumulate in traps associated with the faulted basement highs and graben-type depressions existing at the shelf edge. This geologic setting favors the development of large petroleum accumulations along the shelf edge and graben on the sedimentary basins off central Chile.

    2015-01-01

    Abstract Chile, a middle-income country, recently joined Israel and Singapore as the world’s only countries to require reciprocity as a precondition for organ transplantation. The Chilean reform includes opt-out provisions designed to foster donation and priority for organ transplantation for registered people. Although the reform has had serious difficulties in achieving its mission, it can be reviewed by other countries that seek to address the serious shortage of organs. As increased organ donation can substantially enhance or save more lives, the effect on organ availability due to incentives arising from rules of preference should not be underestimated.

He was a contributor of the Journal. As a prominent surgeon, he introduced different forms of anesthesia, like morphine and atropine, cocaine and methylchloride. He was an organizer of the first Chilean and the first Latin American Medical Congress. In the University he encouraged medical research and helped establish the basic role of the University as a leading institution in the nation. He died in 1903. PMID:2152709

    Chile, a middle-income country, recently joined Israel and Singapore as the world's only countries to require reciprocity as a precondition for organ transplantation. The Chilean reform includes opt-out provisions designed to foster donation and priority for organ transplantation for registered people. Although the reform has had serious difficulties in achieving its mission, it can be reviewed by other countries that seek to address the serious shortage of organs. As increased organ donation can substantially enhance or save more lives, the effect on organ availability due to incentives arising from rules of preference should not be underestimated.

    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 relatively low rate

    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.

    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.

    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.

    On 1 April 2014, a Mw 8.2 earthquake struck off the coast of Iquique, Chile. A tsunami was triggered by this earthquake and caused flooding along the northern coast of Chile. Time series of water surface elevations were recorded at tide gauges and DART (Deep-ocean Assessment and Report of Tsunamis) tsunami sensors in the Pacific Ocean. By comparing the wave spectra of the Iquique event with those of other historical events in this region, we notice the former are characterized with significantly higher energy concentration in high-frequency wave modes. This is an indicator of strong frequency dispersion effects, which can quickly reduce the amplitudes of the leading waves in open ocean. These effects are demonstrated through numerical simulations with a weakly dispersive Boussinesq model. The oceanic propagation of this tsunami is also simulated with MOST (Method of Splitting Tsunami), the numerical simulating tool of NO­AA's tsunami forecast system, termed SIFT (Short-term Inundation Forecasting of Tsunamis). Though MOST is based on the nonlinear shallow-water theory, the numerical dispersion introduced by its finite difference scheme can be manipulated to compensate the neglected physical frequency dispersion, and makes it applicable to dispersive wave propagations.

    Examination of 54 Triatoma infestans from a village near the European Southern Observatory La Silla in Chile and of 9 Triatoma spinolai from the territory of the observatory showed that 10 T. infestans were infected with trypanosomatids. Mice were infected with in vitro cultures initiated with five different trypanosomatid isolates and treated with the immunosuppressive drug cyclophosphamide to increase the parasitemia of the flagellates. Evidence of the presence of T. cruzi was provided by a comparative biometrical analysis of blood trypomastigotes and the occurrence of intracellular amastigotes. Three methods for further identification were used: examination of kDNA ultrastructure, disc electrophoresis of soluble proteins and the Aaptos papillata II lectin induced agglutination. We obtained the following results for all isolates: (1) presence of a central band of the kDNA; (2) T. cruzi specific double bands of the protein patterns; (3) positive reaction with Aaptos papillata II. No differences between the five isolates from Chile and T. cruzi or T. cruzi-like strains from other countries could be observed. Based on these results an infection of the bugs with T. rangeli and T. conorhini could be excluded. PMID:6421021

    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

    We have studied the correlation between the ethnic structure and the prevalence of single gene defects in Chile. At present the Chilean population is approximately 64% white and 35% Amerindian with traces of other admixture. Fewer than 4% of the Chilean population are foreign born. Investigations indicate that all severe diseases and many others without impaired reproduction have mutation rates within the range of the white population. Classical ethnic diseases are very rare. Autosomal recessive disorders have a wide range of variability: cystic fibrosis has a low incidence and PKU has a similar incidence to English rates. Only 30% of the inborn errors of metabolism have been described in Chilean medical publications. In addition, no Chilean haemoglobin or haptoglobin variants have been described. Some rare inherited diseases in Chilean human isolates have been described, including achromatopsia, chondrocalcinosis, and Creutzfeldt-Jakob disease. The prevalence of intrahepatic cholestasis of pregnancy and supernumerary nipples is the highest in the world and they are associated with aboriginal origin. Single gene defects in Chile are probably shaped by factors related to its ethnic population structure. These local rare single gene defects may be good markers of population admixture for genetic epidemiological studies. PMID:7815439

    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.

    Unreliable and data-poor marine fishery landings can lead to a lack of regulatory action in fisheries management. Here we use official Chilean landing reports and non-conventional indicators, such as fishers' perceptions and spearfishing competition results, to provide evidence of reef fishes depletions caused by unregulated spearfishing. Results show that the three largest and most emblematic reef fishes targeted mainly by spearfishers (> 98% of landings) [Graus nigra (vieja negra), Semicossyphus darwini (sheephead or pejeperro), and Medialuna ancietae (acha)] show signs of depletion in terms of abundance and size and that overall the catches of reef fishes have shifted from large carnivore species toward smaller-sized omnivore and herbivore species. Information from two snorkeling speargun world championships (1971 and 2004, Iquique, Chile) and from fishers' perceptions shows the mean size of reef fish to be declining. Although the ecological consequences of reef fish depletion are not fully understood in Chile, evidence of spearfishing depleting temperate reef fishes must be explicitly included in policy debates. This would involve bans or strong restrictions on the use of SCUBA and hookah diving gear for spearfishing, and minimum size limits. It may also involve academic and policy discussions regarding conservation and fisheries management synergies within networks of no-take and territorial user-rights fisheries areas, as a strategy for the sustainable management of temperate and tropical reef fisheries.

    Austrobdella coliumicus n. sp. is described from Coliumo Bay, Chile. It is characterized by a continuous, external coelomic canal (= marginal lacuna), 5 pairs of testisacs, accessory gland cells, a body not distinctly divided into trachelosome and urosome, 2 pairs of dorsal ocelli on the trachelosome, dorsal and ventral segmental ocelli present on the urosome, green overall pigmentation with transverse brown bands, and the absence of conducting tissue. Austrobdella coliumicus is distinguished from other species of Austrobdella by the presence of 2 pairs of ocelli on the trachelosome and a more cylindrical body. It is unusual that this leech was collected from inside the mantle cavity of the razor clam, Ensis macha. Austrobdella losmoliniensis n. sp. is described from the electric ray, Discopyge tschudii, collected at Los Molinos, Chile. It is characterized by a continuous, external coelomic canal; 5 pairs of testisacs; accessory gland cells; a body distinctly divided into trachelosome and urosome; 1 pair of eyes on the oral sucker; overall black pigmentation with unpigmented areas; and the absence of conducting tissue. Austrobdella losmoliniensis can be distinguished from other species of Austrobdella by the combination of 1 pair of eyes on the oral sucker and black pigmentation. PMID:17436961

    Iragüen, D., Urcelay, S., San Martín, B. Pharmacovigilance in veterinary medicine in Chile: a pilot study. J. vet. Pharmacol. Therap.34, 108-115. In Chile, there is no present government policy to survey and analyse adverse drug reactions (ADRs) in the field of veterinary medicine. The intent of this study is to assess, for the first time, ADR frequency in treated animals. To this purpose, a 6-month period pilot study based on WHO recommendations was conducted to monitor ADRs in cats and dogs for frequently used drugs and common labelled signs. Of a total of 149 detected ADRs, 29 (6 in cats and 23 in dogs) were notified by means of ADR report forms, while the rest was identified after reviewing patient clinical records, thus evidencing strong under-reporting problems. More than 70% of ADRs were related to antimicrobials, vaccines and tranquilizers. In dogs, there was a significant effect on ADRs' presentation when acepromazine, amoxicillin, carprofen, ivermectin, sextuple vaccine (polyvalent vaccine that confers immunity against canine distemper virus, canine parvovirus, Leptospira canicola, L. icterohemmoragiae, canine adenovirus type 2 and canine parainfluenza virus) and phytomenadione (subcutaneous injection) were administered. In the case of cats, a significant influence on ADRs was detected when acepromazine, amoxicillin or vitamin K was administered. Present results suggest the need for a pharmacovigilance programme in veterinary medicine for timely ADR-presenting drug detection and drug safety improvement. PMID:21395600

    Scarce information about the epidemiology of historical influenza pandemics in South America prevents complete understanding of pandemic patterns throughout the continent and across different climatic zones. To fill gaps with regard to spatiotemporal patterns of deaths associated with the 1918 influenza pandemic in Chile, we reviewed archival records. We found evidence that multiple pandemic waves at various times of the year and of varying intensities occurred during 1918–1921 and that influenza-related excess deaths peaked during July–August 1919. Pandemic-associated mortality rates were elevated for all age groups, including for adults >50 years of age; elevation from baseline was highest for young adults. Overall, the rate of excess deaths from the pandemic was estimated at 0.94% in Chile, similar to rates reported elsewhere in Latin America, but rates varied ≈10-fold across provinces. Patterns of death during the pandemic were affected by variation in host-specific susceptibility, population density, baseline death rate, and climate. PMID:25341056

    In Chile, the record of dinosaurs in Jurassic and Cretaceous sediments is often restricted to footprints, with few skeletal remains. Tetanuran theropods are known in the Upper Jurassic, and bones of titanosaur sauropods in the Late Cretaceous, including partial skeletons (e.g. Atacamatitan chilensis Kellner et al.). Also from the late Cretaceous, an ornithopod vertebra, a pair of theropod teeth and one tarsometatarsus of a gaviiform bird (Neogaeornis wetzeli Lambrecht) have been reported. The Cenozoic fossil record comprises abundant and well-preserved marine birds from Eocene and Miocene units, with a specially abundant record of Sphenisciformes and less frequently, Procellariiformes. There is an excellent Miocene-Pliocene record of other birds such as Odontopterygiformes, including the most complete skeleton ever found of a pelagornithid, Pelagornis chilensis Mayr and Rubilar-Rogers. Fossil birds are also known from Pliocene and Pleistocene strata. A remarkable collection of birds was discovered in lacustrine sediments of late Pleistocene age associated to human activity. The perspectives in the study of dinosaurs in Chile are promising because plenty of material stored in institutional collections is not described yet. The record of Chilean dinosaurs is relevant for understanding the dynamics and evolution of this group of terrestrial animals in the western edge of Gondwana, while Cenozoic birds from the Region may contribute to the understanding of current biogeography for instance, the effect of the emergence and establishment of the Humboldt Current.

    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.

    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.

    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

    Catastrophe models help (re)insurers to understand the financial implications of catastrophic events such as earthquakes and tsunamis. In earthquake-prone regions such as Chile,(re)insurers need more sophisticated tools to quantify the risks facing their businesses, including models with the ability to estimate secondary losses. The 2010 (M8.8) Maule (Chile) earthquake highlighted the need for quantifying losses from secondary perils such as tsunamis, which can contribute to the overall event losses but are not often modelled. This paper presents some key modelling aspects of a new earthquake catastrophe model for Chile developed by Impact Forecasting in collaboration with Aon Benfield Research partners, focusing on the tsunami component. The model has the capability to model tsunami as a secondary peril - losses due to earthquake (ground-shaking) and induced tsunamis along the Chilean coast are quantified in a probabilistic manner, and also for historical scenarios. The model is implemented in the IF catastrophe modelling platform, ELEMENTS. The probabilistic modelling of earthquake-induced tsunamis uses a stochastic event set that is consistent with the seismic (ground shaking) hazard developed for Chile, representing simulations of earthquake occurrence patterns for the region. Criteria for selecting tsunamigenic events (from the stochastic event set) are proposed which take into consideration earthquake location, depth and the resulting seabed vertical displacement and tsunami inundation depths at the coast. The source modelling software RuptGen by Babeyko (2007) was used to calculate static seabed vertical displacement resulting from earthquake slip. More than 3,600 events were selected for tsunami simulations. Deep and shallow water wave propagation is modelled using the Delft3D modelling suite, which is a state-of-the-art software developed by Deltares. The Delft3D-FLOW module is used in 2-dimensional hydrodynamic simulation settings with non-steady flow

    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

  5. Complexity in Size, Recurrence and Source of Historical Earthquakes and Tsunamis in Central Chile

    Central Chile has a 470-year-long written earthquake history, the longest of any part of the country. Thanks to the early and continuous Spanish settlement of this part of Chile (32°- 35° S), records document destructive earthquakes and tsunamis in 1575, 1647, 1730, 1822, 1906 and 1985. This sequence has promoted the idea that central Chile's large subduction inter-plate earthquakes recur at regular intervals of about 80 years. The last of these earthquakes, in 1985, was even forecast as filling a seismic gap on the thrust boundary between the subducting Nazca Plate and the overriding South America Plate. Following this logic, the next large earthquake in metropolitan Chile will not occur until late in the 21st century. However, here I challenge this conclusion by reporting recently discovered historical evidence in Spain, Japan, Peru, and Chile. This new evidence augments the historical catalog in central Chile, strongly suggests that one of these earthquakes previously assumed to occur on the inter-plate interface in fact occurred elsewhere, and forces the conclusion that another of these earthquakes (and its accompanying tsunami) dwarfed the others. These findings complicate the task of assessing the hazard of future earthquakes in Chile's most populated region.

    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

    The presence of residues of tetracycline, quinolones and antiparasitic drugs was investigated in wild fish captured around salmon aquaculture pens in Cochamó, Region X, Chile. Residues of both antibiotics were found in the meta [corrected] of two species of wild fish that are consumed by humans, robalo (Elginops maclovinus) and cabrilla (Sebastes capensis) [corrected] These findings suggest that the antibiotic usage in salmon aquaculture in Chile has nvironmental implications that may affect human and animal health. More studies are needed in Chile to determine the relevance of these findings for human and animal health and the environment to regulate this use of antibiotics. PMID:17369965

  8. Geomorphic surfaces and supergene enrichment in Northern Chile.

    Supergene enrichment of porphyry copper deposits in the central Andes is thought to be closely correlated with periods of relatively humid climate and the formation of regionally extensive paleosurfaces (e.g. Mortimer, C. 1973) . In northern Chile, two such paleosurfaces have been proposed: the ca. 23 Ma Tarapaca paleosurface within the Coastal Cordillera, and the ca. 10 Ma Pacific paleosurface within the Longitudinal Valley. The Pacific paleosurface is regarded as a single stratigraphic horizon that formed due to either a marked increase in the aridity of the area (Galli-Oliver 1967), regional surface uplift that created a change in the locus of deposition (e.g. Mortimer and Rendic 1975), or a combination of the two. The formation of this surface has been associated with the timing of supergene enrichment throughout the northern Chile and southern Peru (Alpers and Brimhall 1988). Multispectral satellite mapping of the Pacific paleosurface in northern Chile using Landsat, Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and Digital Elevation Model (DEM) imagery, combined with seismic data (Jordan et al. 2010) indicates that the Pacific paleosurface is not a single chronostratigraphic surface, as previously thought, but an amalgamation of surfaces that have both an erosional and depositional history. New in situ cosmogenic exposure dating of alluvial boulders on the paleosurface is combined with previous data (Dunai et al. 2005, Kober et al. 2007 and Evenstar et al., 2009) giving ages ranging from ca. 23 Ma to <1 Ma, supporting a multiphase and much more continuous history. By combining these apparent exposure ages with regional geomorphology, underlying sedimentology, and seismic sections, the geomorphic evolution of the Longitudinal Valley can be constrained. The results show a complex interplay between uplift within the Coastal Cordillera and Precordillera in the south and a distinct change in depositional pattern towards the north. The

    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

    In 1997, UNAIDS decided to implement Drug Access Initiatives (DAI) in four different pilot-countries. We studied the implementation of the DAI in Chile as part of the evaluation program conducted by the ‘Agence Nationale de Recherche sur le SIDA’ (ANRS/France). The objective was to understand how the politico-organizational dynamic influenced the implementation process of the DAI. Approximately 50 semi-directed interviews and observation activities were conducted with the actors who participated in the implementation of the DAI or who played a role in the HIV/AIDS context. The program theory models were established and their evolution analyzed. This article offers an original analysis of an international HIV/AIDS drug access program that was put in place at a time when such programs were seen as a priority by international and governmental institutions. It also offers some insights for the creation of international projects that will be locally implemented. PMID:23230344

    An epidemiologic and seroprevalence survey was conducted (n=830) to assess proportion of persons exposed to hantavirus in IX Region Chile, which accounts for 25% of reported cases of hantavirus cardiopulmonary syndrome. This region has three geographic areas with different disease incidences and a high proportion of aboriginals. Serum samples were tested for immunoglobulin (Ig) G antibodies by enzyme-linked immunosorbent assay against Sin Nombre virus N antigen by strip immunoblot assay against Sin Nombre, Puumala, Río Mamoré, and Seoul N antigens. Samples from six patients were positive for IgG antibodies reactive with Andes virus; all patients lived in the Andes Mountains. Foresting was also associated with seropositivity; but not sex, age, race, rodent exposure, or farming activities. Exposure to hantavirus varies in different communities of IX Region. Absence of history of pneumonia or hospital admission in persons with specific IgG antibodies suggests that infection is clinically inapparent. PMID:12890323

    Hantavirus is endemic to the Region de Los Lagos in southern Chile; its incidence is 8.5 times higher in the communes of the Andean area than in the rest of the region. We analyzed the epidemiologic aspects of the 103 cases diagnosed by serology and the clinical aspects of 80 hospitalized patients during 1995–2012. Cases in this region clearly predominated during winter, whereas in the rest of the country, they occur mostly during summer. Mild, moderate, and severe disease was observed, and the case-fatality rate was 32%. Shock caused death in 75% of those cases; high respiratory frequency and elevated creatinine plasma level were independent factors associated with death. Early clinical suspicion, especially in rural areas, should prompt urgent transfer to a hospital with an intensive care unit and might help decrease the high case-fatality rate. PMID:25816116

    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.

    Objective to explore the cultural experiences of nurses who immigrated to Chile. The study's theoretical framework was the Purnell Model for Cultural Competence. Method Leininger's Observation-Participation-Reflection method was developed at two hospitals in the city of Santiago, and ethnographic interviews were held with 15 immigrant nurses. Results among Purnell's 12 domains, the following were identified: Overview/heritage, Communication, Workforce issues, Family roles and organization, Biocultural ecology and Health-care practices. The difficulties were related to the language and its semantic meaning, the new responsibilities and the difficult relationship with colleagues. "In search of better horizons - the decision to immigrate", "Gaining confidence and establishing a support network - employability and professional performance" and "Seeking for people's acceptance - professional adaptation in a new cultural scenario" are cultural themes that represent their experiences. Conclusions the competence to offer cultural care demands the development of public policies and continuing education programs at health institutions, specifically focused on immigrant nurses.

    The public health system in Chile does not have a comprehensive development policy for physician resources in primary care, so there is currently a significant deficit of hours for medical care. The article contains a proposal for a "General Program for Primary Care Physicians", which aims to reduce the gap of general practitioners and specialists in primary care. The program proposes to integrate newly graduated physicians to work in the public medical offices with the subsequent possibility of applying for a scholarship specialty, and consecutively a return period as a specialist in the public health network. The immediate implementation of this program is perfectly feasible given the current availability of doctors, over 1400 medical graduates from universities. PMID:25826371

    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

    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.

    2016-05-01

    This article starts by reviewing the setbacks that the recent Science and Technology Studies literature has identified in the functioning of technologies of democracy, the different arrangements that look to enact deliberation on technoscientific issues. Putting a focus on the Citizen Consensus Conference, it then proposes that several of these setbacks are related to the kind of "work" that these technologies are expected to do, identifying two kinds of it: performing a laboratory-based experiment and constituting a platform for the dissemination of facts. It then applies this framework to study a Citizen Consensus Conference carried out in Chile in 2003. After a detailed genealogy of the planning, implementation and afterlife of this exercise, the article concludes that several of the limitations experienced are derived from a "successful outcome" conceived as solely running a neat lab-based experiment, arguing for the need to incorporate its functioning as a platform with all the associated transformations and messiness.

    In the 1980s, Chile adopted a mixed (public and private) model for health insurance coverage similar to the one recently outlined by the Affordable Care Act in the United States (US). In such a system, a mix of public and private health plans offer nearly universal coverage using a combined approach of managed competition and subsidies for low-income individuals. This paper uses a "most different" case study design to compare policies implemented in Chile and the US to address self-selection into private insurance. We argue that the implementation of a mixed health insurance system in Chile without the appropriate regulations was complex, and it generated a series of inequities and perverse incentives. The comparison of Chile and the US healthcare reforms examines the different approaches that both countries have used to manage economic competition, address health insurance self-selection and promote solidarity.

    The government of Chile has undertaken a rural electrification program to electrify 75% of the population by the year 2000. Renewable energy is considered within this program, and its application facilitated through a technical cooperation agreement between Chile`s national energy commission (CNE) and the U.S. Department of Energy. In order to introduce isolated mini-grid hybrid wind-energy systems into Chile, three pilot projects were implemented in Region IX. The goal of the pilot systems is to establish renewables as a viable option for rural electrification in the Chilean context. In this paper we report on the first six months of three pilot projects. Presented as background information are brief descriptions of the power systems, data acquisition systems, and the operation and maintenance (O&M) protocols. Analyses of loads, component performance, system operation, and balance of payments for O&M are the primary points presented. Important lessons learned and future plans are also discussed.

    Background Leishmaniasis is an infectious disease endemic today in many areas of South America. Methodology We discovered morphologic and molecular evidence of ancient infections in 4 female skulls in the archaeological cemetery of Coyo Oriente, in the desert of San Pedro de Atacama, Northern Chile. The boney facial lesions visible in the skulls could have been caused by a number of chronic infections including chronic Leishmaniasis. This diagnosis was confirmed using PCR-sequenced analyses of bone fragments from the skulls of the affected individuals.Leishmaniasis is not normally found in the high-altitude desert of Northern Chile; where the harsh climate does not allow the parasite to complete its life cycle. The presence of Leishmaniasis in ancient skulls from the region implies infection by the protozoan in an endemic area–likely, in our subjects, to have been the lowlands of North-Eastern Argentina or in Southern Bolivia. Conclusions We propose that the presence of the disease in ancient times in the high altitude desert of San Pedro de Atacama is the result of an exogamic system of patrilocal marriages, where women from different cultures followed their husbands to their ancestral homes, allowing immigrant women, infected early in life, to be incorporated in the Atacama desert society before they became disfigured by the disease. The present globalization of goods and services and the extraordinary facile movement of people across borders and continents have lead to a resurgence of infectious diseases and re-emergence of infections such as Leishmaniasis. We show here that such factors were already present millennia ago, shaping demographic trends and the epidemiology of infections just as they do today. PMID:19746163

    In this work we characterize risk perception in Chile, based on the psychometric paradigm, exploring the difference between perceived social and personal risk. For this purpose, we conducted a survey including 54 hazards, 16 risk attributes, and 3 risk constructs. The survey, divided into four parts, was administered to 508 residents of Santiago, Chile. Using factor analysis, three main factors, which accounted for 80% of the sample's variance, were identified: factor 1, commonly called "Dread Risk" in the literature, explained 37% of variance; factor 2, "Unknown Risk," explained 28%; and factor 3, which we called "Personal Effect," explained 15% of the variance. On average, individuals perceived themselves as less exposed to risk and with more control and knowledge about them than the general population. OLS regression models were used to test the association of perceived risk with the three main factors. For social risk, factor 1 had the greatest explanatory power, while factor 2 had a negative sign. For personal risk, only factors 2 and 3 were significant, with factor 3 having the greatest explanatory power. Risk denial (defined as the difference between perceived personal and social risk) was associated with factors 1 and 2 only, with factor 2 having a negative sign. The difference between desired and actual regulation levels proved positive for all hazards, thus indicating that Chileans are dissatisfied with the current regulation level for all the hazards analyzed. The comparison of data at the aggregate and at the individual subject's level suggests that while the aggregate analysis overestimates the magnitude of the correlations it still reflects the tendency of the individual responses.

    Purpose When healthcare workers have stigmatizing attitudes toward people living with HIV it may lead to discriminatory behavior that interferes with prevention, treatment, and care. This research examined the HIV-related stigmatizing attitudes reported by health workers in Santiago, Chile. Methods The study used focus group data from the first phase of a larger study to develop and test a HIV prevention intervention for Chilean health workers. Ten focus groups were conducted with Health workers in two communities in Santiago, Chile. Content analysis was used to analyze the data. Results Two central themes emerged: Societal stigma and discrimination towards people living with HIV and healthcare system’s policies related to HIV. Both inaccurate fears of transmission among the general public and Chilean Health workers and societal prejudices against homosexuals contributed to stigmatization and discrimination. Conclusions Health workers did not recognize their own stigmatizing attitudes or discriminatory behaviors, but their discussion indicated that these behaviors and attitudes did exist. Healthcare system issues identified included problems with confidentiality due to the desire to inform other health workers about client HIV status. Health workers must be sensitized to the current stigmatization and misinformation associated with HIV and its negative impacts on persons living with HIV and the general community. Implications All clinical and non-clinical workers at community clinics need mandatory education for HIV prevention that focuses on changing attitudes as well as sharing knowledge. Also, the Chilean law protecting people living with HIV and the confidentiality of their medical care needs to be publicized, along with guidelines for its enactment in clinics and other health facilities.

  8. A numerical study of the upwelling circulation off Central Chile

    NASA Astrophysics Data System (ADS)

    Mesias, Jorge M.

    The summer upwelling circulation off Central Chile between 34°--40°S is studied using the Princeton Ocean Circulation numerical model, implemented with realistic atmospheric forcings and bottom topography. The simulations are made for summers of years 1992, 1993, and 1994. Sea surface temperature (SST) from the model results and satellite sensors (derived from NASA/NOAA Pathfinder Project datasets) are compared to determine regions where the numerical simulations more realistically represent the oceanic fields. The summer local winds are predominantly equatorward and fluctuate affected by the seasonal displacement of the Subtropical Anticyclone of the Southeast Pacific. The model ocean circulation shows the presence of a surface coastal equatorward jet flowing over a poleward undercurrent that spreads over the continental shelf and slope break. These currents resemble those historically observed off Central Chile, following a classical Ekman-geostrophy dynamics. The oceanic variability is strongly related to the variability of the local wind forcing, bottom relief, and coastline geometry. Strong wind fluctuations induce the formation of cyclonic/anticyclonic mesoscale eddies, favored by the separation of the equatorward jet from the coast, downstream of a prominent mid-domain cape. The flow variability between regions depends on the spatial variability of the wind forcing. The wind relaxation is larger in the southern regions, where the upwelling tends to disappear. In the northern areas, the separation of the jet and the formation of eddies induce a strong cross-shelf transport activity. Comparisons among SST fields for all years indicate that the model and satellite fields vary in similar patterns, especially in the northern coastal areas, and suggest that oceanic fields are largely affected by changes in local winds during El Nino events. During El Nino periods, the upwelling activity weakens due to a rapid decrease of the equatorward winds, and the passage of

Conclusion There were significant associations between SES, and access to and use of healthcare among immigrants in Chile and a higher prevalence of no health care provision entitlement among poor and disabled immigrants compared to the Chilean-born. Changing associations between access and use of healthcare and SES among immigrants in Chile over time may reflect changes in their socio-demographic composition or in the survey methodology between 2006 and 2009.

    Monte Patria is the first Municipality in Chile to comply fully with Supreme Decree 686, the Chilean, environmentally-based legislation governing exterior lighting in Northern Chile - the "norma luminica". "Before" and "after" photographs of Monte Patria were published in last June's issue of "Physics Today", in the context of the global effort to control light pollution. Some photographs of other Chilean towns have been obtained for this poster and for display at the International Dark Sky Association's stand at this meeting. Highlights include detailed midnight and dawn panoramas taken by us during October, 2005 - the month in which the six-year "grace period" for all external lighting in northern Chile's astronomically-sensitive 2nd, 3rd and 4th Regions was supposed to come into full compliance. It is clear that significant progress is being made. The chief obstacle has been financial. Large-scale changeout of street lighting requires an outlay of many millions of dollars from cash-strapped municipalities. Chile's central government has moved in to provide financing at the 80-100/% level in many cases. Once Chile's congressional elections are over, we will be able to judge the political will to complete the changeover. Various large mining operations are currently engaged in major lighting changeovers; such changes are especially important in the various mines that are directly visible from existing major observatories in Northern Chile. The importance to astronomy is that full compliance with DS686 will, on average, extend the potential useful life of all the major optical observatories in Northern Chile by several decades. Funding for the Office for the Protection of the Quality of the Skies of Chile (OPCC) is provided by the Chilean National Environment Committee (CONAMA), NOAO, Gemini, ESO and the Las Campanas Observatory of the Carnegie Institute of Washington.

    The IAU's Working Group on Controlling Light Pollution (iauwg) has declared Mauna Kea and a wide strip of Northern Chile between Antofagasta and Chajnanator as top priorities for its efforts to protect existing and potential sites in the Northern and Southern hemispheres respectively. This report provides an update on the iauwg's co-ordinated efforts to protect areas around the major international optical observatories in Chile, as well as the "Chilean Special Zone" (CSZ) mentioned above. This zone is of current and potential interest for the installation of extremely large optical telescopes and includes the ALMA radio-astronomy site. The CSZ is potentially vulnerable to adverse effects of mining in the region. Progess has been made in demonstrating to local mining interests within the CSZ the economic advantages of quality lighting. Educational and outreach activities to a variety of target audiences are building on legislation covering dark skies - itself part of work by the Chilean government to protect the natural heritage of Chile. Substantial good will was generated by an international, bilingual conference held last March in Chile. Just in the region around AURA's Observatory in Chile (Gemini South, CTIO and SOAR), a portable planetarium has been used to reach out to over 600 teachers and 65,000 pupils in the RedLaSer schools network within the last three years. This has attracted the direct interest of Chile's Ministry of Education. Videoconferencing over Internet2 is being used for educational purposes between Chile and various sites in the US. The NSF- initiated Mamalluca municipal observatory now receives more visitors than all the international observatories in Chile combined and is the focus of an expanding local industry of astronomical eco-tourism. Most of this work was supported by funding from, or via, the US NSF through CTIO and Gemini, and from ESO, OCIW, CONAMA and the IDA.

    Salmonella enterica causes health problem worldwide. The relationships among strains that are from the same serotype but different hosts, countries, and continents remain elusive. Few genome sequences are available from S. enterica isolates from South America. Therefore, we sequenced the genomes of 33 strains from diverse sources isolated in Chile and determined that they were of different serotypes. These genomes will improve phylogenetic analysis of Salmonella strains from Chile and the rest of South America. PMID:25792040

    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

    We are undertaking a 1000 hour campaign with the Karl G. Jansky VLA to survey 0.2 square degrees of the COSMOS field in full polarization continuum at 1.4 GHz. Our observations are part of a joint program with the spectral line COSMOS HI Large Extragalactic Survey (CHILES). When complete, we expect our CHILES Continuum Polarization (CHILES Con Pol) survey to reach an SKA-era sensitivity of 500 nJy per 4 arcsecond resolving beam, the deepest view of the radio sky yet. CHILES Con Pol will open new and fertile parameter space, with sensitivity to star formation rates of 10 Msun per year out to an unprecedented redshift of z=2, and ultra-luminous infrared galaxies and sub-millimeter galaxies out to redshifts of z=8 and beyond. This rich resource will extend the utility of radio band studies beyond the usual radio quasar and radio galaxy populations, opening sensitivity to the starforming and radio-quiet AGN populations that form the bulk of extragalactic sources detected in the optical, X-ray, and infrared bands. In this talk I will outline the key science of CHILES Con Pol, including galaxy evolution and novel measurements of intergalactic magnetic fields. I will present initial results from the first 180 hours of the survey and describe our forthcoming Data Release 1. I invite the astronomical community to consider unique science that can be pursued with CHILES Con Pol radio data.

  18. Factors Affecting Growth of Pinus radiata in Chile

    NASA Astrophysics Data System (ADS)

    Alvarez-Munoz, Jose Santos

    The Chilean forestry industry is based on hundreds of thousands of hectares of Pinus radiata plantations that have been established in a variety of soil and climate conditions. This approach has resulted in highly variable plantation productivity even when the best available technology was used. Little information is known about the ecophysiology basis for this variability. We explored the spatial and temporal variation of stand growth in Chile using a network of permanent sample plots from Modelo Nacional de Simulacion de Pino radiata. We hypothesized that the climate would play an important role in the annual variations in productivity. To answer these questions we developed the following projects: (1) Determination of site resource availability from historical data from automatic weather stations (rainfall, temperatures) and a geophysical model for solar irradiation, (2) Determination of peak annual leaf area index (LAI) for selected permanent sample plots using remote sensing technologies, (3) Analysis of soil, climate, canopy and stand factors affecting the Pinus radiata plantation growth and the use efficiency of site resources. For project 1, we estimated solar irradiation using the r.sun , Hargreaves-Samani (HS), and Bristow-Campbell (BC) models and validated model estimates with observations from weather stations. Estimations from a calibrated r.sun model accounted for 94% of the variance (r2=0.94) in monthly mean measured values. The r.sun model performed quite well for a wide range of Chilean conditions when compared with the HS and BC models. Our estimates of global irradiation may be improved with better estimates of cloudiness as they become available. Our model was able to provide spatial estimates of daily, weekly, monthly and yearly solar irradiation. For project 2, we estimated the inter-annual variation of LAI (Leaf Area Index), using remote sensing technologies. We determined LAI using Landsat Thematic Mapper (TM) data covering a 5 year period

    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

    Studies using complex networks are applied to many systems, like traffic, social networks, internet and earth science. In this work we make an analysis using complex networks applied to magnitude of seismicity in the central zone of Chile, we use the preferential attachment in order to construct a seismic network using local magnitudes and the hypocenters of a seismic data set in central Chile. In order to work with a complete catalogue in magnitude, the data associated with the linear part of the Gutenberg-Richter law, with magnitudes greater than 2.7, were taken. We then make a grid in space, so that each seismic event falls into a certain cell, depending on the location of its hypocenter. Now the network is constructed: the first node corresponds to the cell where the first seismic event occurs. The node has an associated number which is the magnitude of the event which occured in it, and a probability is assigned to the node. The probability is a nonlinear mapping of the magnitude (a Gaussian function was taken), so that nodes with lower magnitude events are more likely to be attached to. Each time a new node is added to the network, it is attached to the previous node which has the larger probability; the link is directed from the previous node to the new node. In this way, a directed network is constructed, with a ``preferential attachment''-like growth model, using the magnitudes as the parameter to determine the probability of attachment to future nodes. Several events could occur in the same node. In this case, the probability is calculated using the average of the magnitudes of the events occuring in that node. Once the directed network is finished, the corresponding undirected network is constructed, by making all links symmetric, and eliminating the loops which may appear when two events occur in the same cell. The resulting directed network is found to be scale free (with very low values of the power-law distribution exponent), whereas the undirected

    Andes virus (ANDV) is the predominant etiologic agent of hantavirus cardiopulmonary syndrome (HCPS) in southern South America. In Chile, serologically confirmed human hantavirus infections have occurred throughout a wide latitudinal distribution extending from the regions of Valparaíso (32 to 33 degrees S) to Aysén (46 degrees S) in southern Patagonia. In this study, we found seropositive rodents further north in the Coquimbo region (30 degrees S) in Chile. Rodent seroprevalence was 1.4%, with Oligoryzomys longicaudatus displaying the highest seroprevalence (5.9%), followed by Abrothrix longipilis (1.9%) and other species exhibiting Chile. Phylogenetic analyses showed two major ANDV South (ANDV Sout) clades, congruent with two major Chilean ecoregions, Mediterranean (Chilean matorral [shrubland]) and Valdivian temperate forest. Human and rodent samples grouped according to geographic location. Phylogenetic comparative analyses of portions of S and medium segments (encoding glycoproteins Gn and Gc) from a subset of rodent specimens exhibited similar topologies, corroborating two major ANDV Sout clades in Chile and suggesting that yet unknown factors influence viral gene flow and persistence throughout the two Chilean ecoregions. Genetic algorithms for recombination detection identified recombination events within the S segment. Molecular demographic analyses showed that the virus is undergoing purifying selection and demonstrated a recent exponential growth in the effective number of ANDV Sout infections in Chile that correlates with the increased number of human cases reported. Although we determined virus sequences from four rodent species, our results confirmed O. longicaudatus as the primary ANDV Sout reservoir in Chile. While evidence of geographic differentiation

    Establishing the recurrence time of large-scale tsunami is one of the main objectives of paleotsunami research, as it is fundamental for any tsunami risk assessment. Typically, the result is given in form of the mean recurrence time and a standard deviation as a range of uncertainty, assuming a normally distributed recurrence. We present a 5.5 ka long coastal lake paleotsunami record from south central Chile, which contains 17 tsunami deposits, 9 of which were previously unknown. Our record matches all 3 of the historically known tsunami, as well as all of the 5 known paleotsunami in the region without over- or underrepresentation. We used Bayesian age-depth modelling to calculate an age-depth model and extracted recurrence intervals for 16 recurrence intervals. Our findings confirm the previously published mean tsunami recurrence time on the Valdivia seismic segment of ~300 years. However, our analyses show a strongly bimodal recurrence pattern with one mode at ~115 years and the other mode at ~490 years. The least likely recurrence time between the modes is at ~300 years and coincides with the mean recurrence time. The reasons for the bimodal distribution remain speculative. They can be attributed to either spatial variability, e.g. incomplete segment rupture, splay fault rupture, up- or down-dip rupture, or to temporal variability, e.g. megathrust earthquake clustering, earthquake supercycles. Our findings highlight the importance of recognising the variability in tsunami recurrence patterns before using mean recurrence time for tsunami risk assessment.

    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.

    2016-01-01

    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

  6. Evolution of infant and child mortality in Chile: a model.

    PubMed

    Hojman, D E

    1992-10-01

    The author contends that birth rate and infant and child mortality rates are jointly determined by demographic, economic, health care, and other influences. Working under this structural assumption, a multiequation model is developed, estimated, and simulated, in which real earnings, unemployment, midwife visits, access to cheap energy, public health expenditures, and degree of urbanization are determinant factors of declining infant and child mortality in Chile. Most notably, mortality declined during a period of increasing unemployment and falling living standards for at least part of the population. The study found all 3 rates to be jointly determined, but by different variables. Specifically, unemployment affected birth rate and child mortality rate, while declining infant mortality was based upon midwife visits, health expenditure, and access to cheap energy. At the policy level, trade-offs often result between infant and child mortality, especially where high birth rates prevail. Where movement along the Phillips curve is possible, higher earnings should be preferred over lower unemployment for the benefit of infant and child mortality. Preferred policy would week to provide a carefully balanced combination of better earnings and more midwife visits. PMID:12286009

    The aim of this work was to study the prevalence of hypertension in rural populations of the VIII region of Chile. Six thousand twenty four non institutionalized subjects. 14 years old or older, coming from eight randomly chosen rural communities were studied. Blood pressure was measured by trained personnel in two occasions within 30 minutes; in those classified as hypertensive, a third measurement was performed within 24 hours, eliminating alcohol intake and medications. Results show prevalence rates in the first, second and third measurement of 38.5, 30.8 and 22.8% respectively. The elimination of alcohol intake and medications decreased the prevalence in 3.9%. All the chosen communities has similar rates (19.8 to 21.2%) except Arauco, that had a significantly higher frequency of 31.9%. Zones of extreme ruralness had higher rates than small towns (23.8 vs 21.7%). There was a secular increase in the prevalence of hypertension from 4.9 in the 15 to 24 years old group to 57.8% among people 75 years old or older. Forty three percent of hypertensives were aware of such condition, 26.1% were receiving treatment and in 8.2% it was successful; all these figures were slightly better among women. PMID:8191159

    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.
