Resumen
Uréia, sulfato de amônio, salitre-do-chile e Nitrocálcio, nas doses de 75, 150, 225 e 300kg de nitrogênio por hectare, foram aplicados em experimentos com café Mundo-Novo, instalados em Latossolo Roxo da região de Ribeirão Preto e em Podzólico Vermelho- Amarelo orto da região de Mococa (SP). As produções foram crescentes com os aumentos de nitrogênio aplicado, sendo que as respostas para suas maiores quantidades foram maiores no Podzólico Vermelho-Amarelo orto. O sulfato de amônio, o Nitrocálcio e a uréia mostraram-se superiores ao salitre-do-chile no Podzólico Vermelho-Amarelo orto, apesar de a uréia não apresentar diferenças significativas relativamente ao salitre-do-chile. Em Latossolo Roxo, conquanto houvesse a mesma tendência, as diferenças não foram significativas. O parcelamento das doses de nitrogênio não beneficiou a produção no Latossolo Roxo, porém as produções correspondentes ao parcelamento em quatro vezes foram maiores no Podzólico Vermelho -Amarelo orto.

Resumen
Luego de la gran crisis económica de 1929, la industria del salitre entró en un proceso de reorganización interna con tal de sobrevivir comercialmente y mantenerse como el principal sostén de la economía nacional. En ese sentido, el presente trabajo tiene como finalidad demostrar que la respuesta a ese problema fue el desarrollo de un intento de estanco con características particulares, dando origen a la Compañía de Salitres de Chile (COSACH), tal como sucedió en 1873 con el intento de estanco salitrero peruano que fue la respuesta a la crisis económica de esa década. Analizaremos las diferencias entre uno y otro proceso y explicaremos el origen y ocaso de la COSACH.

Resumen
Usando una variedad de nuevas series de información estadística para los cultivos más importantes, este artículo analiza el desempeño del sector agropecuario durante la Era del Salitre (1880-1930), un periodo de rápida expansión y modernización económica en Chile. El trabajo muestra que en esos años, y especialmente después del cambio del siglo XIX, la producción y el valor real del producto agropecuario aumentaron en la mayoría de los cultivos más importantes, así como en la ganadería. Además, hubo importantes mejoras en la productividad de la tierra, las cuales reflejaron el impacto de cambios tecnológicos, como las innovaciones biológicas. En suma, al contrario de las interpretaciones convencionales que popularizaron la noción de "estancamiento agrícola?, este trabajo demuestra que la agricultura de la Era del Salitre fue un sector mucho más dinámico de lo que se suponía.

Resumen
Nitrocálcio nas quantidades de 60, 120, 180 e 240 gramas de N por cafeeiro e por ano foi aplicado em parcelamentos diferentes, de acordo com os tratamentos e em três locais com início em 1973/74: Centro Experimental de Campinas, Estação Experimental de Mococa e Estação Experimental de Ribeirão Preto. Foram estudados os efeitos das quantidades crescentes e avaliadas as conveniências do parcelamento das doses de N aplicadas. Os acréscimos de produção com a elevação dessas doses foram bastante grandes até 120g, passando, a partir dessa quantidade, a aumentos menores. Os efeitos residuais do sulfato de amônio, Nitrocálcio, uréia e salitre-do-chile aplicados quatro anos antes do início do experimento ainda afetaram as produções, passados dez anos das últimas aplicações, reduzindo-as mais para as correspondentes ao salitre-do-chile e uréia. Os parcelamentos utilizados não favoreceram dados consistentes para conclusões, devendo seu estudo ter continuidade em novas séries de ensaios.

Resumen
La región fronteriza del norte de Chile es un territorio histórico de circulación de población boliviana motivada por las posibilidades laborales de la economía regional y las alternativas comerciales existentes en distintos momentos de su devenir. Si bien Tarapacá no ha sido el destino preferente de la migración boliviana, forma parte del campo migratorio especialmente para los aymara que habitan las zonas más cercanas a la frontera y desde los 90 del siglo pasado para los bolivianos en general. Así de una migración fuerte durante el ciclo de expansión del salitre (1880-1930) se pasó a una más silenciosa y menos visible circunscrita al altiplano y los valles alto andinos para pasar a otra más integrada a lo internacional a partir de la creación de la Zona Franca de Iquique a fines del siglo XX.

Resumen
La Guerra con Chile, también conocida como la Guerra del Pacífico o Guerra del Salitre, no solo trajo destrucción y muerte, también significó el despojo de miles de libros, documentos, instrumentos de laboratorio, colecciones científicas, artísticas, geológicas y arqueológicas. En suma, parte de la memoria histórica creada y acumulada por siglos en la capital del antiguo virreinato del Perú, que resumía y acumulaba en parte la identidad histórica de los peruanos y el legado con el cual se proyecta una república, que pese a sus problemas construía una nación. Lo que presentamos son los avances de una investigación mayor que está en curso y que es un intento de recuperación de una memoria e identidad robadas y que pese al tiempo transcurrido, lamentablemente no es asumida ni por los vencedores ni vencidos, manteniendo a esa lejana guerra viva en la memoria de sus pueblos.

Resumen
O experimento foi conduzido em casa de vegetação da UFSM no período de maio a outubro de 1989. Três plantas de trigo, cultivar BR 14, foram cultivadas em cada vaso (6 litros) com Solo Podzólico Vermelho Amarelo (Unidade de Mapeamento São Pedro), com 70% da capacidade de campo, constituindo a unidade experimental. O delineamento experimental foi inteiramente casualizado, sendo que os tratamentos foram fontes e doses de N, e inoculação das plantas com Septoria nodorum, constituindo um trifatorial com três repetições. As fontes de nitrogênio utilizadas foram uréia e salitre do Chile nas doses de 30, 60, 90 e 120kg/ha de N, sendo parte aplicado na semeadura (30%) e o restante (70%) no estádio 2 (início do afilhamento) da escala proposta por LARGE (1956). Os tratamentos que não foram inoculados com Septoria nodorum apresentaram maior percentagem de N no tecido, o que parece não ter sido afetado tanto com relação a fonte de nitrogênio nem quanto a dose utilizada. O teor de matéria seca, sendo consideradas plantas inoculadas e não inoculadas, não diferiu tanto para fontes como para doses de nitrogênio (kg/ha). A severidade da doença foi maior em plantas que receberam maiores doses de adubação nitrogenada.

Resumen
La naturaleza, con todas sus interpretaciones objetivas y/o subjetivas, ha sido designada y representada en sus más variadas formas, respondiendo quizás siempre a un interés o una función coyuntural que nunca es neutra. Quizás esa versatilidad conceptual la ha conllevado a convertirse en un contenido vacío y sin novedad política. Por mucho tiempo se intentó minimizar aquellos atisbos ecológicos propiciados por Marx en El Capital, sin embargo, la idea de intercambio orgánico entre la sociedad y la naturaleza utilizada como crítica ambiental en siglo XIX, sirvió para comprender algunos hechos históricos que se sucedían entre Europa y aquellos incipientes territorios industriales.De esta manera América Latina (en general), y Perú-Bolivia y Chile (en particular) conocieron un auge transitorio en la explotación de nutrientes, minerales y sales con fines agrícolas e incluso bélicos. La interrelación suscitada bajo este “boom” del guano y el salitre, generó la mayor demanda en la fertilidad del suelo y el trabajo humano hasta ese entonces conocido. Fue esa distribución ecológica desigual entre las necesidades y las satisfacciones derivadas de la producción y explotación del valor de uso en la naturaleza, que llevó a repensar un análisis holístico y dialéctico, que considerara la realidad material de un momento determinado para explicar las crisis ambientales y el desarrollo desigual en el espacio.Palabras claves: Naturaleza y Sociedad, Metabolismo socio-natural, Fractura metabólica, Crisis ambiental, Renta del suelo.

Resumen
Se analiza la construcción social de los ayllus como lugares de síntesis e integración de la geografía física con la geografía humana sobre la base de los postulados de la Geografía Física Crítica, para lo cual se consideran las principales características de los climas y geoformas de los paisajes naturales de la Cordillera de los Andes y los impactos de la minería sobre los ecosistemas y comunidades, destacando las controversias sobre disponibilidad y usos de las aguas superficiales y subterráneas. Las cuencas son examinadas como conceptos fundamentales en la epistemología y ontología de las comunidades andinas, destacando la presencia de topoclimas y redes hidrosociales que corresponden a algunas de las relaciones culturales y políticas que definen la geografía física crítica de los territorios de ayllus. La minería del salitre, del cobre y más recientemente del litio, da cuenta de la centralidad ecológica, histórica, política y económica que juega el Desierto de Atacama, que reúne en su territorio las regiones más áridas del planeta con la mayor concentración mundial de minerales metálicos y no metálicos. Dado el rol crítico que desempeña la disponibilidad y acceso a las fuentes de agua, las comunidades han intentado resistir las intervenciones exógenas sobre sus territorios reconociendo la integridad de los procesos biogeofísicos que regulan el ciclo hidrológico de las cuencas y resaltando los ciclos hidrocosmológicos que asocian los componentes físicos y metafísicos como parte de sistemas de sustento de la vida, expresados en una organización espacio-cultural que vincula los pisos ecológicos controlados por la altura, como las actividades agrícolas y ganaderas y manifestaciones culturales y religiosas que transcurren durante el año. Sin embargo, el auge del extractivismo minero por parte de poderosas empresas nacionales y extranjeras, que ha caracterizado al desarrollo económico chileno durante las últimas décadas, ha impulsado y ejecutado negociaciones entre comunidades locales y empresas transnacionales, realizadas en el marco de un Estado neoliberal, que están conduciendo al colapso de los sistemas naturales y socio-culturales y con ello al desaparecimiento de los ayllus como territorios de vida.

Resumen
Este artículo se ocupa de la resistencia política, a propósito de los campos de concentración implementados en la dictadura chilena cívico militar (1973 – 1990). Al respecto, las nociones de resistencia política y de campos de concentración, son precisadas desde una perspectiva interdisciplinaria atendiendo a las complejidades y debates que comprenden tanto el contexto histórico político como el marco espacial en que se producen y que corresponde, en este caso, a la oficina salitrera de Chacabuco (1924 – 1938) actual sitio patrimonial, cuyo funcionamiento operativo fue entre noviembre de 1973 y abril de 1975. Estos antecedentes, permiten formular como principal supuesto, que la resistencia política comprende estrategias de sobrevivencia que no solo mantienen la dignidad y los derechos humanos, sino también formas de reorganización social y ofensivas que contemplan acciones políticas, sociales y culturales. Como metodología, se consideran entrevistas semiestructuradas y revisión de material testimonial, ya publicados, de sobrevivientes. Las fuentes secundarias son de tipo académicas y de prensa. Son de especial interés, los relatos de quienes actualmente se autodenominan “Chacabucanos”, detenidos oriundos de Concepción, trasladados desde el Estadio Regional a Chacabuco, que tenían una historia de vinculación política previa, que definió estrategias de resistencia aún vigentes.

Resumen
A red chili plant (Capsicum spp.) is one of the horticultural commodities in Indonesia which has good economic value, so it has priority to be developed. Agriculture practices in Java island have partly switched to coastal areas which have characteristics of saline soils. Saline soils are alkaline and nutrient-poor, especially essential nutrients such as P and N. One way to restore fertility in saline soils used beneficial and fertilizing bacteria such as PGPR. Plant growth-promoting rhizobacteria (PGPR) are free-living, soil-borne bacteria, which are capable of enhancing the growth of the plant either directly or indirectly. The objectives of this research were to determain the effect of PGPR isolates to the growth of red chili plants in saline sandy soil and to determine the best PGPR isolate capable to improve the growth of red chili plant in saline sandy soil. The result showed that the inoculation of rhizobacteria significantly affected to plant height and root length of the red chili plant (Capsicum annum). The combination of 3 PGPR isolates (Azospirillum PSA 10, Azotobacter PSA 8, and Marinococcus PSA 1) was the best result in increasing the height and root length of the chili plant (Capsicum annum).

Resumen
The utilization of saline soil for chili pepper production might be established by selecting tolerant varieties so that the growth and production remain stable even though they are planted on marginal lands. The purpose of this study was to determine the selection criteria for tolerant chili pepper to salinity and select a chili pepper genotype that are tolerant to salinity based on morphological characters and yield components. This study was carried out in Kolaka Regency, Southeast Sulawesi, from November 2020 to May 2021. The study was carried out on saline land nearby the coast with an average of electrical conductivity (EC) of 6.66 dS m-1. The study used a randomized complete block design with 22 lines of elite chili pepper and three replications. The results showed that characters as selection criteria for salinity tolerant were plant height, days to flowering, days to harvest, and fruit length because they had a significant effect on fruit weight per plant and high broad-sense heritability of 81.53%, 94.75%, 95.05%, and 87.45%, respectively. Based on these characters, the genotype selected as a candidate for the tolerant variety was G17. This genotype can be recommended for the development of chili pepper in saline soil.

Resumen
Freshwater availability is declining in most of semi-arid and arid regions across the world, including the southwestern United States. The use of marginal quality groundwater has been increasing for sustaining agriculture in these arid regions. Reverse Osmosis (RO) can treat brackish groundwater, but the possibility of using an RO concentrate for irrigation needs further exploration. This greenhouse study evaluates the water use and yield responses of five selected chile pepper (Capsicum annuum L.) cultivars irrigated with natural brackish groundwater and RO concentrate. The four saline water treatments used for irrigation were tap water with an electrical conductivity (EC) of 0.6 dS m−1 (control), groundwater with EC 3 and 5 dS m−1, and an RO concentrate with EC 8 dS m−1. The evapotranspiration (ET) of all chile pepper cultivars decreased and the leaching fraction (LF) increased, particularly in the 5 dS m−1 and 8 dS m−1 irrigation treatments. Based on the water use efficiency (WUE) of the selected chile pepper cultivars, brackish water with an EC ≤ 3 dS/m could be used for irrigation in scarce freshwater areas while maintaining the appropriate LFs. A piecewise linear function resulted in a threshold soil electrical conductivity (ECe) ranging between 1.0–1.3 dS m−1 for the tested chile pepper cultivars. Both piecewise linear and sigmoid non-linear functions suggested that the yield reductions in chile peppers irrigated with Ca2+ rich brackish groundwater were less than those reported in studies using an NaCl-dominant saline solution. Further research is needed to understand the role of supplementary calcium in improving the salt tolerance of chile peppers.

En los últimos años se han realizado estudios, mediante Técnicas No Destructivas (TND), los que han determinado que la torre se encuentra en buen estado. No obstante, existen dudas respecto a las reales dimensiones de los elementos constructivos afectados por el desfibrado. El presente estudio tuvo como objetivo evaluar elementos de madera desfibrada, de la torre de lixiviación de la oficina salitrera Santa Laura, mediante la técnica de resistografía. Estudios adicionales de ultrasonido y xilohigrometría también fueron desarrollados. Los resultados obtenidos establecen que la disminución de las dimensiones de los elementos evaluados no presenta diferencia significativa y que no existen daños profundos en las maderas. El estudio confirma que el edificio no se encuentra en riesgo.

Resumen
Chile peppers are economically important crops in southern regions of the United States. Limited information is available on irrigation management with low-quality water or on salt-affected soils. The objective of this study was to determine the relative salt tolerance of 20 genotypes of chile peppers. In Expt. 1, seeds of selected pepper types (Anaheim, Ancho, Cayenne, Paprika, Jalapeño, Habanero, and Serrano) were germinated in potting mix and seedlings were grown in 2.6-L pots. Six weeks after sowing, salinity treatments were initiated by irrigating plants with nutrient solutions of different electrical conductivities (ECs): 1.4 (control), 3.0, or 6.0 dS·m−1. After 1 month of initiating treatments, shoots were harvested and dry weights were determined. All plants survived and no visual salt injury was observed regardless of pepper variety and treatment. There were no statistical differences between control and saline solution treatments in final height and shoot dry weight of Habanero 1, ‘Early Jalapeño’, ‘AZ-20’, ‘NuMex Joe E. Parker’, and ‘NuMex Sandia’. In Expt. 2, seeds of 20 genotypes were directly sown in 2.6-L containers filled with loamy sand. Saline water irrigation was initiated 37 days after sowing by irrigating plants either with saline (nutrient solution based, similar to Expt. 1) or nutrient solution (control). More than half the genotypes did not have 100% survival in the salinity treatment. Ancho 1, Ancho 2, Cayenne 1, ‘Early Jalapeño’, and ‘AZ-20’ had 100% survival regardless of salinity treatment. No plants of ‘TAM Mild Habanero’ survived when irrigated with saline water and less than half of the plants survived in the control. The relative tolerance of chile genotypes to salinity varied with substrate in some genotypes. From the combined results of the two experiments, the 20 pepper genotypes were ranked for salt tolerance based on seedling survival, visual quality, and growth. ‘Early Jalapeño’ and ‘AZ-20’ were relatively tolerant to salinity among the 20 genotypes, whereas ‘TAM Mild Habanero’ and ‘Ben Villalon’ were sensitive. Ancho 1, Ancho 2, Cayenne 1, and Cayenne 2 also had relatively high tolerance based on survival and visual quality, although shoot growth was reduced significantly.

Resumen
The Chilean saline lakes are distributed mainly in the Atacama desert in northern Chile and the southern Patagonian plains. The scarce studies are restricted mainly to northern Chilean saline lakes, and these revealed that the main component in these ecosystems are the halophylic copepod Boeckella poopoensis Marsh 1906, or the brine shrimp Artemia franciscana (Kellog, 1906), and both species do not coexist. The present study consisted of field observations in zooplankton assemblages in southern Chilean saline lakes (51-53 ºS). These first observations revealed three different patterns, one saline lake only with A. persimilis (Piccinelli and Prosdocimi, 1968), a second lake only with B. poopensis, and a third lake with A. persimilis, B. poopoensis and unidentified harpacticoid copepod. These results are different in comparison with the observations in the literature that described the non-coexistence between B. poopoensis with brine shrimps. Ecological and biogeographical topics were discussed.

Resumen
Hyponatremia is one of the most common electrolyte abnormalities encountered in the clinical setting in hospitalized patients. The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is the leading cause of hyponatremia in most of these cases. While fluid restriction, hypertonic saline infusion, diuretics, and the treatment of underlying conditions constitute the first line of treatment of SIADH, in refractory cases, and especially for pediatric patients, there seems not to be any other choice for treatment. Tolvaptan, although its use in pediatric patients is still very limited, might be an attractive treatment option for correction of hyponatremia due to SIADH. Here we present a pediatric case of SIADH that was resistant to treatment with fluid restriction and hypertonic saline infusion and was treated successfully with tolvaptan. Tolvaptan could be a good, safe, and effective treatment option in pediatric SIADH cases that are resistant to treatment. However, the dosage should be titrated carefully.

Resumen
AbstractEvaporites within Upper Triassic to Lower Cretaceous sequences in the Atacama region of northern Chile are interpreted as the deposits of continental and coastal saline lakes. Halite casts and finely laminated calcareous evaporites, intercalated with alluvial and fluvial sediments, are probably playa lake deposits. These continental evaporites have been recognized in Upper Triassic alluvial sediments (Cifuncho Formation), in Upper Triassic–Lower Jurassic braided river deposits (basal unit of the Pan de Azúcar Formation), and within a sequence of Lower Cretaceous aeolian, alluvial and playa lake mudflat sediments (Quebrada Monardes Formation). Lower Cretaceous evaporites between marine limestones (Lautaro Formation) and continental redbeds (Quebrada Monardes Formation) were probably deposited in coastal saline lagoons, produced during a regionally extensive marine regression.These sequences, and other similar successions in northern Chile, provide a record of almost continuous evaporite deposition, and hence of arid to semi-arid conditions, since Upper Triassic times. These conditions were primarily the result of a constant latitudinal position within the subtropical zone. A contributary factor was the geographical position of the area, initially on the west coast of Gondwanaland and subsequently on the coast of South America, with cold, northward-flowing ocean currents and offshore winds.

Resumen
Ornamental chile peppers are popular bedding plants. As high-quality water supply becomes limited in many parts of the world, alternative waters such as municipal reclaimed water is encouraged to be used for landscape irrigation. The purpose of this study was to assess the relative salt tolerance of 10 cultivars of ornamental chile peppers by irrigating the mature plants with saline solutions and germinating seeds in saline substrate in a greenhouse. In the mature plant salt tolerance experiment, plants were irrigated with nutrient solution (no addition of salts, control) or saline solution at electrical conductance (EC) of 4.1 dS·m−1 or 8.1 dS·m−1 for 8 weeks. Plants in the EC of 4.1 dS·m−1 treatment did not have any foliar salt damage regardless of cultivar. At EC of 8.1 dS·m−1, ‘NuMex Memorial Day’ had the most severe foliar salt damage, whereas ‘NuMex April Fool’s Day’, ‘NuMex Cinco de Mayo’, ‘NuMex Thanksgiving’, and ‘NuMex Twilight’ had little or no foliar damage. Shoot dry weight (DW) reduction at EC of 8.1 dS·m−1 compared with control was smallest in ‘NuMex Thanksgiving’ (15%), whereas ‘NuMex Memorial Day’ had the greatest reduction of 74% followed by ‘NuMex Christmas’ of 61%. The highest shoot DW reduction in ‘NuMex Memorial Day’ coincided with lowest visual score, indicating that this cultivar was the least tolerant to salinity. The leaf Na+ and Cl− concentrations increased dramatically with increasing EC of the irrigation water in all cultivars. The highest Na+ concentration of 10.9 mg·g−1 DW at EC of 8.1 dS·m−1 was observed in ‘NuMex Christmas’. The highest Cl− concentration at EC of 8.1 dS·m−1 was found in ‘NuMex Memorial Day’ with 64.8 mg·g−1 DW, which was four times higher than the control. In the seedling emergence experiment, seeds of the 10 cultivars were germinated in substrate either moistened with reverse osmosis water (EC ≈0) or saline solution at EC of 17.1 dS·m−1. ‘NuMex Christmas’ and ‘NuMex Memorial Day’ had the lowest relative seedling emergence index, indicating that these two cultivars were the least tolerant to salinity during the seedling emergence stage. ‘NuMex Thanksgiving’ and ‘NuMex Cinco de Mayo’ had the highest relative seedling emergence index. Combining the results from both experiments, we concluded that ‘NuMex Cinco de Mayo’ and ‘NuMex Thanksgiving’ were the most tolerant cultivars, whereas ‘NuMex Christmas’ and ‘NuMex Memorial Day’ were the least tolerant ones.

Resumen
The Valdivia River estuary (VRE) located in south-central Chile is known as one of the largest estuarine ecosystems on the Pacific coast. This research aims to determine the intra-tidal and sub-tidal variability of saline intrusions into the VRE between November 2017 and March 2019 derived from salinity sensors located along the VRE. Complementary hydrographic measurements were conducted during flood and ebb conditions of the spring and neap tides for each of the four seasons of the year along the central axis of the VRE. The results of the salinity time series showed that saline intrusions (values greater than 0.5 Practical Salinity Units) occurred ~20 km from the estuary mouth, when the total flow of the Cruces and Calle-Calle rivers (main tributaries of the estuary) was low, around 280–300 m3 s−1. During the same period, the best co-variability was observed between the saline intrusions and the mixed-semidiurnal tide and the fortnightly and monthly periods of the tide. Regression analyses indicated that salinity intrusion length (L) is best correlated to discharge (D) with a fractional power model L α D−1/2.64 (R2 = 0.88). The decreasing discharge trend, found between 2008–2019, implies that saline water intrusions would negatively impact the Valdivia’s main drinking water intake during the low rainfall season under future climate conditions.

Resumen
Crustacean communities in saline lakes are regulated mainly by salinity, and a significant inverse correlation can be found between salinity and species richness. The aim of the present study is to compare the carcinological diversity of two distinct arid regions of the world: Algerian saline lakes, locally called “chotts” and “sebkhas”, and their Chilean Altiplano counterparts, and to determine if there are similar regulator patterns that influence the composition of those communities. The main halophilic taxon common to both regions was the anostracan Artemia at high salinities. However, many other halotolerant crustaceans may occur in Algerian chotts and sebkhas, such as Phallocryptus spinosa, Branchinectella media, Moina salina, Cletocamptus retrogressus, Arctodiaptomus salinus and Heterocypris sp. In Chilean saline lakes the calanoid copepod Boeckella poopoensis was an important component of zooplankton at high salinities, while ostracods were totally absent. The results of correlation analysis revealed a significant inverse correlation between salinity and species number (Algeria, , , p-value = 0.0032; Chile, , ; p-value < 0.0165). The results of null model analysis describing species co-occurrence showed that the species communities are random for Algerian saline lakes due to the presence of many halotolerant species. For Chilean saline lakes, the species communities are structured.

Resumen
Cerebral salt wasting (CSW) syndrome is an important cause of hyponatremia in head injuries apart from syndrome of inappropriate antidiuretic hormone (SIADH). Proper diagnosis and differentiation between these two entities are necessary for management as the treatment is quite opposite in both conditions. Fludrocortisone can help in managing CSW where alone saline infusion does not work. We report a 17-month-old female child with head injury managed successfully with saline infusion and fludrocortisone.

Resumen
AbstractA thick succession of continental redbeds was deposited in a 50 km wide intra-arc basin on the Andean active continental margin in the Atacama region of northern Chile during early Cretaceous times. Upper Jurassic to early Cretaceous marine limestones were buried by the seaward progradation of a succession of coastal dunes, saline lakes and sandflats. Aeolian dune fields migrating towards the east across these coastal plains became stabilized by the growth of vegetation. Interdune alluvial areas between the sand dunes and dune fields developed into extensive alluvial braid plains which were in turn superimposed by alluvial fans. These fans were inundated by a regionally extensive saline lake produced by tectonic or volcanic damming of the sedimentary basin. This lake dried up leaving a large area of playa-lake mudflats. The climate was warm and semi-arid with a low and seasonal rainfall. Parts of the area supported a substantial vegetation of woody plants, together with a vertebrate fauna of dinosaurs, pterosaurs and crocodiles. The continental redbeds were derived from a volcanic source and were deposited on continental crust in a deep but narrow, north-south elongated, fault-bounded graben. This extensional basin formed in an intra-arc setting within an active andesitic volcanic chain. Upwards-coarsening sedimentary successions were the product of uplift of the fault-bounded margins of the basin.

Resumen
Abstract The presence of the calanoid copepod Boeckella gracilis (Daday, 1902) in Chilean seasonal pools has been only poorly studied as yet. The aim of the present study thus is to investigate the role of conductivity and temperature on the relative and absolute abundance of B. gracilis in seasonal coastal pools in the Araucania region (38°S, Chile). The results of correlation analysis revealed the presence of a significant inverse correlation between conductivity and relative abundance, whereas no significant correlations were found between conductivity and absolute abundance, between temperature and absolute abundance, and between temperature and relative abundance. These results agree partially with similar observations for mountain pools in the same region, but they would not agree with observations for calanoids of saline and subsaline inland waters in the northern and southern extremes of Chile. Considering this scenario, the species would show different populational responses to environmental stress in different situations, which phenomenon deserves to be studied more extensively and in more detail.

Se discute sobre la formación de la identidad, la trayectoria y experiencia de sus habitantes; sobre la ciudad, que fue concebida bajo principios de la tradición utópica, y sus cambios en el emplazamiento. Se pone énfasis en el proceso de transformación a campamento y luego a un interés de patrimonialización del complejo urbano. Esta última forma, observada como manifestación de los cambios sufridos a partir del predominio de un nuevo modelo de acumulación, cuyos ejes están dados por la competitividad, la flexibilidad laboral, la producción de calidad y la globalización, que marcan nuevas relaciones con el espacio por parte de los habitantes y los trabajadores.

Resumen
Being adapted to saline environments, halophytes are plant species that have received considerable attention due to their ability to cope with environmental stress factors, such as high concentrations of soluble salts and heavy metals. In this work, we focused on determining if the Sarcocornia neei (S. neei) plant can be considered as an indicator of heavy metal pollution in soil. This was done by analyzing the concentration of cadmium (Cd), lead (Pb), copper (Cu), and arsenic (As) in plants and soil sampled from two wetlands in the central zone of Chile: a wetland contaminated by industrial activities and a wetland protected by the Chilean government. In addition, 14 fertility parameters (pH, electrical conductivity, organic matter, nitrogen (N), phosphorus (P), potassium (K), sodium (Na), Pb, calcium (Ca), magnesium (Mg), Manganese (Mn), zinc (Zn), iron (Fe), and boron (B)) were analyzed for soil samples in both wetlands. This was done to differentiate between available elements and contamination by heavy metals. Plant and soil samples in the contaminated wetland exhibited significantly higher heavy metal concentrations in comparison to samples analyzed from the protected wetland. This indicates that the S. neei plant can be further researched as an indicator of heavy metal pollution in saline soils and possibly for phytoremediation purposes.

Resumen
A one year 3 month old child undergoing fronto-orbital advancement surgery for metopic craniosynostosis had severe bleeding when the surgeon attempted to remove bone flap. Head-end elevation was given at the surgeon’s request to reduce bleeding. Immediately there was a drastic fall in end tidal carbon dioxide (ETCO) and arterial saturation (SpO). Considering air embolism, fraction of inspired oxygen (FiO) was increased to 100% and the surgeon filled the field with saline and covered the area with wet gauze. The operating table was leveled. The child continued to deteriorate with the cardiac rhythm changing to pulseless electrical activity and asystole. Incremental bolus doses of adrenaline, blood products transfusion, fluid bolus and infusion of inotropes were given. Chest compression was not done as the endotracheal tube was fixed to the chest of the patient. Tube dislodgement without access to the head-end of the patient would have been a disaster. The child became hemodynamically stable, the surgery continued and the child was extubated the next day. Other than focal seizures which responded to levetiracetam, the child had no neurological deficits.

Resumen
Background: Bronchiolitis is the leading cause of acute illness and hospitalization in young children. There is limited role for diagnostic laboratory or radiographic tests in typical cases of bronchiolitis. Several large recent trials have revealed lack of efficacy of either bronchodilators or corticosteroids. Novel treatment like hypertonic saline and adrenaline nebulizations need to be evaluated for their efficacy.Methods: In this retrospective case control study, we included children aged between 6 months to 2 years admitted for bronchiolitis between August 2017 till July 2018. Each of the 45 children treated with adrenaline nebulisation was assigned a child who was given hypertonic saline nebulization only matched for age and duration of symptoms.Results: 45 children given adrenaline nebulization and 45 children given only hypertonic saline nebulization were compared. Mean duration of stay for children treated with adrenaline nebulization was 5.3 days and those given hypertonic saline was 4.8 days. p value of 0.29.Conclusions: Adrenaline nebulization did not shorten hospital stay in children admitted for bronchiolitis as compared to children given hypertonic saline.

Resumen
Objectives: To study the effect of subtenon lidocaine injection at the end of intervention on the post-operative emergence agitation in pediatric strabismus surgery under general anesthesia with sevofluran. Material: We studied 191 children patients undergoing muscle surgery for strabismus from 2-6 years old. Children were (prospectively) randomized to one of the four groups. These groups include: A –Group Sevofluran fentanyl; B –Group sevoflurane fentanyl, Subtenon lidocaine injection; C – Group Propofol, fentanyl, sevofluran; and D – Group Propofol, fentanyl, Sevoflurane, Subtenon lidocaine injection. In the beginning of the induction of anesthesia, children received dexametasone and metoclopropamide. At the end of the surgery, children received either lidocaine (2%) or normal saline (1ml) into the subtenons space. This was conducted on the recovery room using five scoring scale. These scale include: 1- the child makes eye contact, 2- Purposeful response after repeated stimuli, 3 – the child is aware of the surrounding environment, 4- severe restlessness, and 5 – The child is inconsolable. The degree of emergence agitation was observed. Furthermore, the score 4 and 5 was considered as an emergence agitation. Results: There are no differences regarding age and weight. The incidence of emergence agitation was significantly lower in the groups which were receiving subtenon lidocaine compared with saline group injections (p< 0.05). Conclusions: A lidocaine injection into subtenon space reduces the emergence agitation after general anesthesia in pediatric strabismus surgery.

Resumen
The response of chile pepper to salinity and infection by Phytophthora capsici was assessed under greenhouse conditions in plants susceptible or resistant to P. capsici. Additionally, the effect of salinity on mycelial growth and production of sporangia and zoospores by P. capsici was evaluated in the laboratory. Salinity treatments consisted of varying levels of electrical conductivity (from 1.8 to 14.4 dS/m) achieved by amending irrigation water or growth media with a mixture of sodium chloride and calcium chloride. In plants susceptible to P. capsici, disease severity increased by approximately 1.3 to 2.7-fold with increasing salinity level, whereas no such effect was observed in plants resistant to P. capsici. Mycelial dry weight increased by 8 to 16%, and radial growth of mycelium was augmented by 5 to 30% with increase in salinity level. Production of sporangia and zoospore formation were reduced by approximately 3 to 85 and 1 to 93%, respectively, under saline conditions. These results indicate that salinity may predispose susceptible chile pepper plants to infection by P. capsici.
