    Full Text Available We analyze the individual motives of political party affiliation as a central variable that help us to characterize the party affiliation as a practice and as belonging to a party organization. The study was conducted through questionnaires, and the sample was integrated by 428 citizens over 18 and under 65 years old, from Cordoba, Argentina. We propose a categorization of the motives of affiliation, inductively constructed, that recovers the theoretical conceptualization from the sociology of the organizations and the socio-cognitive psychology. Likewise, we analyze the relationship between the different affiliation motives, the party and electoral practices, and the perception of efficiency and importance that the affiliation has for the participants.

    Agua de Ramon district is located in the NW of Cordoba, Argentina, between 3 49' and 30 0 52' S and 65 0 21' and 65 0 24' W, in the Eastern Pampean Range setting. It was a very important tungsten district until the end of 1950'decade when tungsten mining became of no economic interest. The objective is to report for the first time the petrological, mineralogical and geochemical characteristics of several marble lenses located in the sourthern of the area. Marble outcrops are lenticular ranging from 1 m to 80 m in length and 0.50 m to 20 m width. They appear massive, fine-grained and in light colors (white, pale green, very light brown and pale gray). These last varieties show a distinct banded structure due to little differences in color. These marbles are mainly composed of magnesian calcite accompanied by minor amounts of dolomite, forsterite, humite group minerals, tremolite, talc, serpentine and clinochlore, and scheelite, sphene, apatite and opaque minerals like hematite, magnetite, illmenite, pirrothite and pyrite as accessory minerals. Major chemical analyses indicate a relatively high SiO2 and MgO content, and minor CaO, in comparison with marbles of this type. Mineral paragenesis was useful to evaluate metamorphism conditions in this area [es

    The potential for hydrogen production from wind resources in the province of Cordoba, second consumer of fossil fuels for transportation in Argentina, is analyzed. Three aspects of the problem are considered: the evaluation of the hydrogen resource from wind power, the analysis of the production costs via electrolysis and the annual requirements of wind energy to generate hydrogen to fuel the vehicular transport of the province. Different scenarios were considered, including pure hydrogen as well as the so-called CNG plus, where hydrogen is mixed with compressed natural gas in a 20% V/V dilution of the former. The potential for hydrogen production from wind resources is analyzed for each department of the province, excluding those regions not suited for wind farms. The analysis takes into account the efficiency of the electrolyzer and the capacity factor of the wind power system. It is concluded that the automotive transportation could be supplied by hydrogen stemming from wind resources via electrolysis. (author)

    Full Text Available This article will analyze the police practices enabled by the Misdemeanors Code of Córdoba-Argentina. Most countries have "administrative" laws that authorize the use of state coercion without judicial review or participation. This use of the state coercive power transforms executive state officers and police officers in micro-dictators. Whether it is immigration laws in Central Europe, "vagrancy" laws in Venezuela, "loafers" act in Bolivia, bylaws in USA municipalities or Codes of Conduct in Argentina; almost every western country have or have had misdemeanor legislation that criminalize acts by using ambiguous terms and producing large spaces for administrative arbitrariness. In the province of Cordoba-Argentina, the Misdemeanors penalizes with arrest-day behaviours such as ‘disturbing prostitution,’ ‘refusal to identify,’ ‘prowl,’ among other figures of dubious constitutionality. Moreover, the prosecution for the commission of these offenses is carried directly by the police officers without judicial intervention or participation of a lawyer. Penalties include fines and arrest, although the last sentence is the most widespread application. Thus, from police practices authorized by misdemeanor legislation we will analyze the implications of hyper- misdemeanor-incarceration in control societies. Detentions by the application of the misdemeanors code exceeds five times the number of arrests for the violation of the Criminal Code. Key words: Control Societies, misdemeanour, police.

    Orchidaceae is a highly dependent group on the Rhizoctonia complex that includes Ceratorhiza, Moniliopsis, Epulorhiza and Rhizoctonia, for seed germination and the development of new orchid plants. Thus, the isolation and identification of orchid mycorrhizal fungi are important to understand the orchid-fungus relationship, which can lead to the development of efficient conservation strategies by in vivo germination of seeds from endangered orchid plants. The aim of our work was to isolate and characterize the different mycorrhizal fungi found in roots of terrestrial orchids from Cordoba (Argentina), and, to learn about the natural habit and fungal associations in the Chaco Serrano woodland pristine region. In this study, bloomed orchid root and rhizosphere soil samples were obtained in two times from Valle de Punilla during spring of 2007; samples were kept in plastic bags until processed within 48 hours, and mycorrhizal condition confirmed assessing peloton presence. A total of 23 isolates of the orchideous mycorrhizal Rhizoctonia complex were obtained. The isolates were studied based on morphological characters and ITS-rDNA sequences. Morphological characteristics as color of colonies, texture, growth rate, hyphal diameter and length and presence of sclerotia were observed on culture media. To define the number of nuclei per cell, the isolates were grown in Petri dishes containing water-agar (WA) for three days at 25 degrees C and stained with Safranine-O solution. The mycorrhizal fungi were grouped into binucleate (MSGib, 10 isolates) and multinucleate (MSGim, 13 isolates) based on morphological characteristics of the colonies. We obtained the ITS1-5.8s-ITS4 region that was amplified using primers ITSI and ITS4. Based on DNA sequencing, isolates Q23 and Q29 were found to be related to species of Ceratobasidium. Isolates Q24 and Q4 were related to the binucleated anastomosis group AG-C of Rhizoctonia sp. The rest of the isolates grouped in the Ceratobasidium

    The General Health Questionnaire (GHQ-12) is a commonly used instrument to screen for psychiatric distress. However, the psychometric properties and reliability of the GHQ-12 in Argentina and, more specifically, in the city of Cordoba, have not previously been studied. To assess the psychometric properties and reliability of GHQ-12 in adult consultants of primary care in Cordoba, Argentina. Using probabilistic sampling in primary care centers in the city of Cordoba, a cross-sectional study was conducted. The Spanish version of the GHQ-12 was administered. The psychometric properties, including internal consistency and factor structure, for the Spanish version of the GHQ-12 were measured. 854 primary care consultants were included in the study. The questionnaire had high internal consistency, with a Cronbach's alpha of 0.80. An exploratory factor analysis suggested a two-factor model, similar to what has been reported for the original questionnaire. The GHQ-12 showed good psychometric properties and reliability in the studied population.

  11. Hydrological behaviour of sealing under different soil management conditions in the Center South Cordoba, Argentina

    The susceptibility of soils to form seals induced by rain depends on a combination of physical, chemical and biological processes, which are, indeed, affected by climatic characteristics and the type of soil. If we consider the weather factors, the energy of rain, as a function of quantity and intensity, is the most important one. The soil properties that favor the formation of sealing are texture, organic matter content, structural stability and sodium adsorption relationship. Regarding texture, silt is the particle, which is most highly involved. In central Argentina, specifically in the central southern region of Cordoba Province, the most representative soils show a low content of clays and a high content of silt and fine sand. This land has undergone different production systems, not only agricultural ones but also combined systems, as summer crops, with intense labouring and scarce, even lacking, stubble supply. Therefore these soils have had important loss in organic matter, degradation of the structure of the superficial horizons. It became necessary, then, to look for a combination of technologies leading to an energy input throughout conservation tillage systems, soil covering and agrochemicals which tend to improve soil quality in order to obtain a sustainable production. The trial was conducted by using a simple at-random design with two repetitions for each treatment. Only in F the initial saturated hydraulic conductivity (K si ) (non-sealing condition) and the final hydraulic conductivity (K sf ) (sealing conditions) were determined in the superficial of soil in 2000, by means of a rain simulator using an intensity up to 50 mm/h for 60 minutes (kinetic energy of 0.1336 J.cm -2 ). The K s values obtained by applying Darcy's equation were used to fit the Horton type exponential decay function which describes Ks as a function of the time of exposure to a simulated rain. It can be concluded that the removal of natural vegetation and crop systems have

    Since 1999, a new, epidemic, methicillin-resistant Staphylococcus aureus (MRSA) strain, named the “Cordobes clone,” has emerged in Argentina and coexists with the pandemic Brazilian clone. The purpose of this study was to determine the stability over time of the new clone and to investigate its evolutionary relationship with epidemic international MRSA lineages and with other MRSA and methicillin-susceptible S. aureus (MSSA) major clones distributed in this region. One hundred three MRSA isolates recovered in 2001 from Cordoba, Argentina, hospitals and 31 MSSA strains collected from 1999 to 2002 were analyzed by their antibiotic resistance patterns, phage typing, and pulsed-field gel electrophoresis. Additionally, representative members of most MRSA defined genotypes (A, B, C, E, K, and I) were characterized by multilocus sequence typing (MLST) and spaA and SCCmec typing. The most prevalent MSSA pulsotypes were also analyzed by MLST. Our results support the displacement of the Brazilian clone (sequence type [ST] 239, spaA type WGKAOMQ, SCCmec type IIIA) by the Cordobes clone (ST5, spaA type TIMEMDMGMGMK, SCCmec type I) in the hospital environment. MRSA and MSSA isolates shared only ST5. The data support the origin of the Cordobes clone as a member of a lineage that includes the pediatric and New York/Japan international clones and that is genetically related to the British EMRSA-3 strain. Interestingly, the pediatric clone, isolated from most community-acquired infections in Cordoba, was characterized by ST100, a single-locus variant of ST5 and a new variant of SCCmec type related to SCCmec type IVc.

    Geochemical characteristics of ground waters related with lixiviation, transport and precipitation of uranium in the Conlara river valley (provinces of San Luis and Cordoba (Argentina)) are studied. Anions and cations' distributions, together with hardness, specific conductivity, pH, Eh, and uranium and vanadium contents, have been studied. Those parameters characterize four hidrogeochemical facies along an E-W profile: a calcic strong bicarbonate facies, an alkaline-calcic bicarbonate facies, an alkaline sulfate facies, and a strong alkaline sulfate facies. An ''Interphase zone'' (transition from bicarbonate water to sulfate water), where changes in composition may define a geochemical environment capable of UO2 precipitation, has been determined. The chemical-Thermodynamic studies give a dominance of UDC and UTC complexs ions (even in sulfate waters), so they represent the 99% of present ions. Besides, the calculated values required for equilibrium with uraninite or carnotite resulted much greater than those obtained in the performed experiments. It means that the precipitation of those minerals requires either the presence of greate amounts of uranium or vanadium, or a reducing environment with Eh values smaller than the observed ones. Finally, the steps to be taken in future investigations are suggested in view to a drilling plan where: 1) Priority to the ''Interphase zone'' areas is given. 2) The deepest aquifers in Tertiary sediments of the basin have to be reached in order to get the convenient environmental conditions (i.e. smallest Eh values) for uranium or uranium-vanadium precipitation.

    The purpose of the study was to assess the differences in health-related quality of life (HRQoL) according to academic performance (AP) in children who attend public schools in the city of Cordoba, Argentina. Cross-sectional study carried out in a sample of 494 children aged 9-12 years (mean = 9.5; standard deviation [SD] = 0.65; IQR 1) who attended 4th grade of public schools in the city of Córdoba, Argentina in 2014. HRQoL was assessed by self-administration of the KIDSCREEN-52 child version in classroom. AP was established with the final grades in language and mathematics obtained from the school records. Marginal means and SD's of the HRQoL scores were compared between AP groups by calculating the effect size (ES), and linear mixed effect models were used to evaluate the (independent) association of AP with HRQoL. Statistically significant differences were found in the psychosocial dimensions of the HRQoL between the AP groups. The main differences in HRQoL between children with very good-excellent grades and those with unsatisfactory AP were found in school environment (ES = 0.69), parent relation and home life (ES = 0.61), autonomy (ES = 0.61), self-perception (ES = 0.49), and social acceptance (ES = 0.48). Children with very good-excellent grades scored better in all of these dimensions. Children with very good-excellent grades in language and mathematics scored better in the psychosocial domains of HRQoL. AP is an important factor in the analysis of the social and psychological aspects of children's health. Further research is required to explore more deeply the direction and characteristics of this association.

    This work presents the results obtained during the first stage of the investigations carried out in the Mar Chiquita lake (Cordoba Province, Argentine Republic) within the framework of the Coordinated Research Programme (CRP) on ''Isotope Techniques in Lake Dynamics Investigations'' of the International Atomic Energy Agency. The main objectives are to contribute to the study of this huge water body that in the past two decades increased its size almost three folds, to establish its water balance and to asses the influence of the climatic changes on the water budget. This water body is the final receptacle of a large closed basin formed mainly by the rivers Dulce, Suquia and Xanaes. During 1890-1973 it occupied 1800 to 2000 km 2 with a salinity of 310-250 g/L. At present, it has around 5000 km 2 , a maximum depth of 10-12 m and a salinity rounding 42 g/L. The changes in salinity and size are related to an increase in precipitation which, at the same time, depends on different palaeoclimatic conditions. From a scientific point of view it is also important to study the lake hydrological balance, its groundwater input and output as well as the evaporation rate and the mean residence time. These latter considerations are the object of the present isotopic research. Future studies will consider a paleoclimatic approach. (author)

    Full Text Available Most of the researchers who work with rural development subjects agree that the social organizations are essential for the rural population to play a role in their own development. Therefore, the organization is a necessary condition for the rural development, and the problem lies in establishing the correct methodology to promote it. In Copacabana, a rural town in the northern mountainous province of Cordoba, we ask: How does one handle family farmers, tensions between individual strategy, and collective action to solve their problems? We conclude that for campesinos is not easy to allocate the social investments required to develop a long-lasting organization. Campesinos’ wishes to reap the benefits stemming from organization are not enough to actually develop a reliable organization. It is also required an appropriate balance between the individualistic tendencies of their members and their collective needs. To overcome the tensions arising within organizations it is necessary to create a process of constructive participation that allows (a that the whole group becomes committed with the aims originally proposed, but at the same time to be flexible enough to modify and recreate them; and (b to establish a set of rules allowing the access to new members, and transparent mechanisms of social control which are accepted and shared by all members. In many cases this process may be favored by the participation of external social actors

In the present work, the most important etho-ecological differences (reproduction habitat, call site, daily and seasonal activity of species that constitute the communities of southern Cordoba Province are indicated, and a classification of advertisement calls is provided. The anuran fauna of the plain area of the southern-central Córdoba Province is represented by 9 species of leptodactylids belonging to 5 genera (Leptodactylus gracilis, L. mystacinus, L. latinasus latinasus, L. ocellatus, Pleurodema tucumanum, Physalaemus biligonigerus, Odontophlynus americanus, Ceratophrys cranwelli and C. ornata, 2 species of bufonids (Bufo arenarum and B. fernandezae and one hylid (Hyla pulchella pulchella. The acoustic records obtained in the field during the reproductive period were analyzed through a program of sound digital analysis comparing the following parameters: dominant frequency, call duration and interval between calls; descriptions regarding type of call and modulation were also made. Three types of basic calls were recognized based on duration; this category was sub-divided depending on the shape of the oscillographic image. Results of this analysis revea] marked differences between advertisement calls, mainly at the level of dominant frequency ranges and call duration. This partition of sound space represents a mechanism of mating isolation that minimizes the interaction between sympatric species that breed at the same time.

    Data of an old spectrometry gamma-ray survey carried out in the Sierras Pampeanas Range by the National Atomic Energy Commission (Argentina) were reprocessed to obtain a corrected digital archive. The geochemical interpretation of the 250 x 250 meters spectrometric grids from the Achala batholith area was based on the behaviour of the radioelements in a peraluminous magma. Spectrometric maps of potassium, uranium, thorium and their ratios were used. In particular, the Th grid was very useful to define the primary magmatic evolution of the granitoids. K and U correlate roughly with Th distribution. The observed positive correlation between Th and U is thought to be the result of surficial leaching of U from uraninite. Finally, U/Th ratio allows to determine both, the magmatic evolution of the rocks and the mineral phase responsible for U content. (author)

    Full Text Available St. Louis encephalitis virus is a complex zoonoses. In 2005, 47 laboratory-confirmed and probable clinical cases of SLEV infection were reported in Córdoba, Argentina. Although the causes of 2005 outbreak remain unknown, they might be related not only to virological factors, but also to ecological and environmental conditions. We hypothesized that one of the factors for SLE reemergence in Córdoba, Argentina, was the introduction of a new SLEV genotype (SLEV genotype III, with no previous activity in the area. In order to evaluate this hypothesis we carried out a molecular characterization of SLEV detections from mosquitoes collected between 2001 and 2004 in Córdoba city. A total of 315 mosquito pools (11,002 individuals including 12 mosquitoes species were analyzed. Overall, 20 pools (8 mosquitoes species were positive for SLEV. During this study, genotypes II, V and VII were detected. No mosquito pool infected with genotype III was detected before the 2005 outbreak. Genotype V was found every year and in the 8 sampled sites. Genotypes II and VII showed limited temporal and spatial activities. We cannot dismiss the association of genotype II and V as etiological agents during the outbreak. However, the silent circulation of other SLEV strains in Córdoba city before the 2005 outbreak suggests that the introduction of genotype III was an important factor associated to this event. Not mutually exclusive, other factors such as changes in avian hosts and mosquitoes vectors communities, driven by climatic and environmental modifications, should also be taken into consideration in further studies.

    Vitamin D deficiency is defined when blood levels of 25-hydroxyvitamin D (25 (OH) D) is less than ng / mmol/L. The status of Vitamin D level is associated with clinical, pathological and physiological changes as increased of parathyroid hormone, bone remodeling, osteoporosis and increased risk of fractures. Moreover,vitamin D and its metabolites are known to be associated with multiple chronic diseases as diabetes mellitus, autoimmune, cardiovascular and neoplasia diseases. To assess the vitamin D status in a rural population of Córdoba Province in Argentina and its relation with bone mineral density. We prospectively studied 31 patients over 50 years old who live in a rural population of Pampa de Achala in Córdoba Province, Argentina. This city is located in Córdoba High mountains. Blood vitamin D levels were tested in 24 patients and Bone mineral density in 31 patients. Vitamin D level was determined by HPLC. The vitamin D level were considered normal between 20-50 ng/ml in the winter season and 20-80 ng/ml in the summer season. Bone mineral density of lumbar spine and femoral neck was measured by DXA GE LUNAR DPX-L, according to World Health organization classification (37). The data were analyzed by Spearman coefficient and Chi cuadrado. The vitamin D levels samples were available in 24 patients. Mean blood Vitamin D level was 24.54 ng /ml. 8 of them (33%) had vitamin D level less than 20ng/ ml. 83% (20) of the analysed patients had vitamin D level less than 30 ng/ml and only 4 patients has vitamin D level more than 30 ng/ml. Low bone mineral density of lumbar spine and femoral neck was found in 66 % of the patients. 19 % of the patients were diagnosed of lumbar spine and femoral neck osteoporosis and 29 % of them had lumbar spine meanwhile 25 % had femoral neck. There was not statistically significant association between vitamin D level and bone mineral density analysed by Chi Cuadrado (p<0.07). A significant association was found between blood vitamin D

    To determine the case distribution of accidental ophidism in the Córdoba province of Argentina, identify high risk areas, and evaluate the usefulness of the SIGEpi software program (Pan American Health Organization, Washington, DC, United States of America). Information regarding the 299 cases of accidental ophidism reported in Córdoba in 1995-2006 was collected from the Provincial Epidemiology Department's official records of incidents involving venomous creatures. The SIGEpi software program was used for geographic mapping. Specific maps were produced to identify, quantify, and visualize the danger zones and areas of high risk for ophidism. The incidents occurred mostly in the northern and western areas of the province. Snakes of the Bothrops genus were responsible for the majority of the incidents (87.7% of the total). The departments with the highest annual incidence rates were Pocho and Río Seco (> 10 incidents per 100,000 residents). Three ophidism high-risk zones were identified: one in far west of the province, another in the far north, and another just north of Bañados del Río Dulce and the Mar Chiquita lagoon. Accidental ophidism constitutes a major health problem in the Córdoba province where incidence rates are higher than those areas with more severe economic issues tied to rural labor. SIGEpi software is a reasonable choice for studying public health challenges and proved to be effective in identifying areas at high risk for ophidism.

    To assess the level of exposure to pesticides and its correlation with perceived health indicators and injury biomarkers (genotoxic alterations and those caused by butyrylcholinesterase enzyme activity) in the population of pesticide applicators in extensive crops (PAEC) in Córdoba, Argentina. Transversal study, in PAEC (n = 47) randomly selected from a sample of 2000, and non-exposed subject controls (n = 52). The sociodemographic variables, exposure conditioning, and perceived health were surveyed by means of a self-administered questionnaire; biological indicators of genotoxicity: micronuclei, chromosomal aberrations and kite assay, and butyrylcholinesterase activity. 40% of PAEC have over 10 years' length of service and almost 50% of them reside less than 500 m from the sprinkled fields; they report low rates of personal protective equipment use while mixing, applying, or repairing the equipment. General, cardio-respiratory, and dermatological symptoms were greater among PAEC (p <0.05) as well as indicators of genotoxic injury (p <0.001). The butyrylcholinesterase activity was negatively associated with levels of exposure to pesticides. The PAEC show an important negative impact on health linked to exposure to pesticides. The exposure scales associated to the use of biomarkers were a useful tool for monitoring pesticide applicators' health. Copyright © 2018 SESPAS. Publicado por Elsevier España, S.L.U.

    Laguna Mar Chiquita is one of the largest water bodies of South America. It is a big lake of saline waters, and its geographic localization is SOMS' S, 62 deg 30' W, about 150 km Northwest of Cordoba, Argentina. Due to its large variability of hydrological budget, surface and water levels produced periods of low stands (LLP) and high stands (HLP). This fluctuation of water level also produces substantial changes in the water salinity. The principal tributary of the Laguna Mar Chiquita is Dulce River and also receives water from two other rivers: Suquia and Xanaes. The Suquia River drains in a small satellite lake, the Laguna del Plata. The purpose of the present work was to investigate the sediment composition of the Laguna Mar Chiquita (2 sediment cores) and del Plata (one sediment core) by using Neutron Activation Analysis (NAA) technique. The three 60 cm long sediment cores, sliced each 2 cm, were analyzed and 26 elements were determined (As, Ba, Br, Ce, Co, Cr, Cs, Eu, Fe, Hf, La, Lu, Na, Nd, Rb, Sb, Sc, Se, Sm, Ta, Tb, Th, U, Yb, Zn e Zr). Other complementary techniques were utilized: macro elements (Al, Ca, Fe, K, Mg, Mn, Na, P, Si, Ti) were determined by X-ray fluorescence, and the mineralogical composition of the sediments was determined by X-ray diffraction. The results obtained did not show any indication of anthropic contribution in the sediment composition, and concentration of the majority of the elements analyzed is uniform along the entire profile of the analyzed core. Statistical analysis of elemental concentrations (Cluster Analysis) reflects that in Laguna del Plata the fine fractions of the sediments is dominated by detrital minerals, while in the Laguna Mar Chiquita, the neo formed minerals are the principal components. In both lakes, it was possible to identify compositional variations in the sediment segments, which may correspond to temporal fluctuations in the sedimentation conditions. The statistical analysis associated to sedimentation

    The lichen Ramalina celastri (Spreng.) Krog. and Swinsc. was used to study trace-element atmospheric pollution in Cordoba (Argentina). 38 samples from a 1999 campaign were analyzed by NAA and a number of physiological parameters was determined. In first-ever comparisons, no correlations were found between altitude, physiological parameters and determined elements, which allowed the full comparison of element data in lichen samples throughout the whole survey area. After the application of Monte Carlo assisted factor analysis to the elemental matrix, five source profiles were found and mapped. The attribution of the sources is discussed. (author)

    The museums of Botany, Mineralogy and Zoology of the Facultad de Ciencias Físico-Matemáticas were created along with a world wide phenomenon, defined by some authors as the "museum movement," in a time the basics of this movement were being restructured. Thus, this work intends to go over the building stage of the natural history museums in a peripheral domain --- Cordoba by the end of the 19th century --- in order to partially understand this transition process. The strategy is to analyze the collections and find out how and why they were gathered. Two other aspects are also relevant: the human resources and the funds these institutions were granted.

    The Cordoba and Wolsung projects mark the entry into the international sales arena of the standardized Canadian 600 MWe CANDU-PHW reactor design. The Cordoba station experienced a setback in the early stages when severe inflation in Argentina led to a renegotiation of the contract. However, following this, good progress has been made and the current forecast completion date in 1980 is expected to be achieved. The Wolsung project experienced difficulties early in the project due to site conditions, so that site work commenced some 9-10 months later than originally planned. These difficulties had predictable effects upon the progress of site-related engineering and it is expected that the project completion date will be somewhat delayed

    Full Text Available En el siguiente artículo desarrollaremos cómo el culto y la fiesta de celebración a San Sebastián en Las Ovejas sufrió en estos últimos años una serie de transformaciones que están en estrecha relación con cambios institucionales de la Iglesia Católica, la vida política y económica de la Argentina y más específicamente de la provincia de Neuquén. La reapertura democrática argentina en 1983, y al casi simultáneo proyecto de integración económica del Cono Sur americano, denominado Mercosur, está implicando que economías nacionales relativamente cerradas se vayan abriendo e integrando en un solo mercado con la finalidad de conseguir mayor competitividad y asegurar mercados. Esto exige que las fronteras internacionales se tornen más permeables. La heterogeneidad de actores (sacerdotes, políticos, devotos, etc. e intereses (económicos, turísticos, religiosos, etc. de la fiesta indican su multivocalidad; y como el propio origen de la celebración está ligado al corte de las relaciones intercordilleranas hacia mitad del siglo XX, la devoción a San Sebastián aparece como un mediador entre la localidad y la nación argentina, su pasado chileno y la institucionalidad de la Iglesia Católica. Finalmente, el análisis de la organización y el significado de la celebración nos permite entonces reflexionar sobre ciertas categorías clásicas y en apariencia antagónicas de la antropología como tradición/innovación o conflicto/armonía.

    This discussion of Argentina covers geography, the people, history and political conditions, government, economy, foreign relations, and relations between the US and Argentina. In 1985, the population of Argentina was estimated to be 30.6 million with an estimated annual growth rate of 1.5%. The infant mortality rate is 34.1/1000, and life expectancy is 70.2 years. Argentina, which shares land borders with Bolivia, Brazil, Chile, Paraguay, and Uruguay, is bounded by the Atlantic and the Antarctic Oceans. Descendants of Italian and Spanish immigrants predominate in Argentina, but many trace their origins to British and West and East European ancestors. In recent years, there has been a substantial influx of immigrants from neighboring Latin American countries. The native Indian population, estimated to be 50,000, is concentrated in the peripheral provinces of the north, northwest, and south. What is now Argentina was discovered in 1516 by the Spanish navigator Juan de Solia. The formal declaration of independence from Spain was made on July 9, 1816. In the late 19th century, 2 forces worked to create the modern Argentine nation: the introduction of modern agricultural techniques and the integration of Argentina into the world economy. Argentina has impressive human and natural resources, but political conflict and uneven economic performance since World War II have impeded full realization of its considerable potential. Yet, it is one of the wealthiest countries in Latin America. Among the reasons for the military coup of March 1976 was the deteriorating economy, caused by declining production and rampant inflation. Under the leadership of the Minister of the Economy, the military government focused attention on those immediate problems, and, in 1978, embarked on a new development strategy focusing on the establishment of a free market economy. There was little improvement in the economy, and a new economic plan was introduced in 1985 which has capped inflation by

    Full Text Available The aim of this study was to study the sexual dimorphism in adult Chaetophractus villosus (Desmarest, 1804, from northern Patagonia, Argentina. Eight mandibular traits were measured in 37 males and 34 females. Univariate and multivariate morphometric analysis were applied to the data set. Results showed that C. villosus was sexually dimorphic, with higher absolute values corresponding to females. The total length of the mandible was the most important variable to discriminate sexes, followed by the height at the level of the last tooth and body length. The percentages of sex discrimination were high, as they were when a new sample (17 males, 13 females was tested. Females have larger mandibles than males independently of their larger cranial size. They also showed a higher degree of correlation between variables, suggesting a more stable shape for the mandible than in males.O presente estudo examinou o dimorfismo sexual dos adultos de Chaetophractus villosus (Desmarest, 1804 do norte da Patagônia Argentina. Oito parâmetros mandibulares foram medidos em 37 machos e 34 fêmeas. Análises morfométricas univariada e multivariada foram aplicadas à série de dados. Os resultados mostraram que C. villosus apresenta dimorfismo sexual, com todos os valores absolutos mais elevados nas fêmeas. O comprimento total da mandíbula foi a variável mais importante para discriminar os sexos, seguidos pela altura no nível dos últimos dentes e pelo comprimento do corpo da mandíbula. As porcentagens de discriminação dos sexos foram elevadas, quando uma amostra nova (17 machos, 13 fêmeas foi testada. As fêmeas têm as mandíbulas maiores que os machos, independentemente de seu tamanho cranial maior. Mostraram também um grau mais elevado de correlação entre variáveis, sugerindo uma forma mais estável para a mandíbula que nos machos.

    Argentina has embarked on an ambitious domestic nuclear research and energy program. The venture promises to provide the nation with the infrastructure to play an important role in the nuclear export market in the years ahead. Buenos Aires built its program on a foundation of international support and assistance that overlay an emerging sophisticated industrial and scientific establishment. The foreign contribution sensitized Argentina to opportunities in the global market. This paper reports that Argentina operates two heavy-water/natural uranium reactors, Atucha I and Embalse. Producing, respectively, 320 MW(e) and 600 MW(e), they supply roughly 10 percent of the country's electricity. With a capacity factor of 84 percent, Atucha I is among the best operated plants in the world. Plans call for a third, 745 MW(e) power plant, Atucha II, to go on line in the early 1990s. During this period, construction also may begin on three 300 MW(e) plants, although the country's foreign indebtedness plus cost overruns in earlier construction will place a heavy burden on these plans

The age interval (1780–1806 was obtained by means of the archeomagnetism using the SHA.DIF.14k geomagnetic field prediction model. This age corresponds to the stage of the Rodriguez administration (1772–1809, in particular the period of Jose Rodriguez and his son Manuel, since later the property was rented out.

    Full text: In this work measurements of the Radon ( 222 Rn) concentration in the inside of historical buildings which date back to the end of the 17th and the beginning of the 18th Centuries have been carried out in the city of Cordoba (Argentina). Meteorological factors such as room temperature and atmospheric pressure have not shown to affect, to a great extent, the results obtained. By comparing the concentration of 222 Rn in environments at different levels we inferred that the soil underlying the buildings does not represent an important source of 222 Rn. The main occurrence of the element was found in room walls, which shows that local building materials are an important source of 222 Rn. Among the materials used in these buildings are granitic rocks, and to a lesser extent, lime, sand and marble. The 222 Rn concentrations recorded in some of the rooms surveyed reach values which are close to the minimum intervene level set by international standards in 4pCi/l. The study of the effects of ventilation in the concentration of 222 Rn allows us to conclude that its values decrease to accepted levels by means of a natural and efficient ventilation of the rooms.

Estudios de comunidades de líquenes en relación a los incendios forestales, han demostrado como responden al fuego por encima de las variables microambientales que modelan la comunidad en ausencia de este disturbio. El objetivo de la presente contribución es reconocer el efecto del fuego en la comunidad de líquenes del Bosque Serrano en Córdoba. Se seleccionaron dos zonas, una testigo y otra sometida a fuego en 1996. A través de un muestreo sistemático y estandarizado se relevó la presencia y cobertura de especies de líquenes en árboles y arbustos en las dos áreas estudiadas. Entre el área testigo y el incendiado la diversidad y cobertura de líquenes es similar pero varia su composición. Las especies en la zona incendiadas corresponden a líquenes heliófilos y adaptados a situaciones de estrés. El fuego como disturbio frecuente favorece la presencia de pocas especies con importantes coberturas que resistan las condiciones que el disturbio impone. Los incendios de alta intensidad y frecuencia dejan a la comunidad de líquenes sin posibilidades de desarrollo, disminuyendo la diversidad general y la calidad de los sistemas forestales en los que viven.Lichens are recognized bioindicators of environmental quality. Studies of lichen communities in relation to forest fires have shown the response to fire over micro-environmental variables that shape the community in the absence of this disturbance.

Methods: Gender and clinical and laboratory data were evaluated by descriptive statistics, non-parametric survival analysis, and generalized linear models at the beginning of the study (diagnosis and at the end (hospital records, n=209. Results: At diagnosis, women (n=28, 13.4% had a higher probability of being asymptomatic than men (n=181, 86.6%. High viremia was associated with advanced clinical stages, but was inversely related to CD4 count. Truncated Kaplan-Meier curves were similar for both sexes. The probability of not having AIDS criteria at the end of the study was higher in patients without these criteria at diagnosis. Women had a higher probability of having AIDS at the end of the follow-up than men. In contrast, men had a higher prevalence of venereal diseases (n=38, 21%, dysmetabolic profile (n=14, 7.7% and positive serology for opportunists (n=31, 17.1%. Marker diseases were mainly represented by internal mycosis and waste syndrome, although less specific findings (anemia, oral lesions were also associated with progression. Conclusions: Using an integrative approach, high viremia was critically linked to clinical and lymphocyte impairment. Early diagnosis was a major determinant of clinical course, with women having a worse prognosis. However, men were diagnosed in clinically advanced stages and with other non-HIV-related entities, which could affect progression. These findings should be integrated into the planning of preventive strategies.Objetivos: Establecer la influencia de la condición médica al diagnóstico y del sexo en la evolución del VIH/Sida determinada por factores clínico-biológicos en pacientes de la ciudad de Córdoba (Argentina, 1995-2005.

    Measurements of radon concentration at homes are usual activities in the last years at the countries with uranium in their soils. On the other hand, the man's radiological protection about radiation is related to the environmental actions for a healthy life, but not much known for a public. The great quantities of ore with uranium can be an important source of irradiation when they are used as building materials. The soils are important too for the emanations of radon in the interior of buildings and for these reasons, the radon concentration measurements in Cordoba familiar houses were implemented in the summer of 1991. The Alpha Track Technique and the results obtained indicate the need of other measurements and a winter measurement for investigation variations of radon concentration. The typical values measured were low, about 4.13 Bq/m 3 if they are compared with other Argentine values measured. This paper discusses the procedure, techniques and criteria used in the work held in Cordoba city, Argentina. (Author)

    In September 2009, considering the existing interest in public communication of scientific activities that are developed locally, a group of researchers and communicators from Córdoba, decided to form the Network of Outreach of Córdoba. Its stated objectives of the Constitutive Act are presented in this paper along with the main activities undertaken to date and plans for the future. Since that time, the Management of Institutional Relations of the CNEA in Córdoba became involved in public circulation of scientific knowledge, in what has proven to be a framework that ensures an adequate level of debate to present nuclear national activities. This will involve collaborative efforts with professional institutions involved in research, teaching and communicating science. The main objective was to encourage the transfer of knowledge to optimize available resources, improving the methodological approaches and generating creative products tailored to regional needs, in order to promote the democratization of science and nuclear technology. This paper consists of two parts. On the one hand describes the activities of the Network during the year 2011 shows results with particular emphasis on topics related to atomic energy, and secondly, shows the desirability of promoting such activities in the CNEA. Among the main actions considered, highlighting the institutional participation in the official Ministry of Science and Technology Fair participation in Science and Technology Provincial Cordoba 2011, issue of the radio program 'Green Light: Science and technology everyday life' by National Technological University Radio and a network of forty provincial stations, and active participation in the Course of Specialization in Public Communication of Science and Scientific Journalism, organized by the School of Information Sciences and the Faculty of Mathematics, Physics and Astronomy, National University of Cordoba, among others.

    Particulate matter (PM) is one of the major harmful pollutants to public health and the environment [1]. In developed countries, specific air-quality legislation establishes limit values for PM metrics (e.g., PM10, PM2.5) to protect the citizens health (e.g., European Commission Directive 2008/50, US Clean Air Act). Extensive PM measuring networks therefore exist in these countries to comply with the legislation. In less developed countries air quality monitoring networks are still lacking and satellite-based datasets could represent a valid alternative to fill observational gaps. The main PM (or aerosol) parameter retrieved from satellite is the 'aerosol optical depth' (AOD), an optical parameter quantifying the aerosol load in the whole atmospheric column. Datasets from the MODIS sensors on board of the NASA spacecrafts TERRA and AQUA are among the longest records of AOD from space. However, although extremely useful in regional and global studies, the standard 10 km-resolution MODIS AOD product is not suitable to be employed at the urban scale. Recently, a new algorithm called Multi-Angle Implementation of Atmospheric Correction (MAIAC) was developed for MODIS, providing AOD at 1 km resolution [2]. In this work, the MAIAC AOD retrievals over the decade 2003-2013 were employed to investigate the spatiotemporal variation of atmospheric aerosols over the Argentinean city of Cordoba and its surroundings, an area where a very scarce dataset of in situ PM data is available. The MAIAC retrievals over the city were firstly validated using a 'ground truth' AOD dataset from the Cordoba sunphotometer operating within the global AERONET network [3]. This validation showed the good performances of the MAIAC algorithm in the area. The satellite MAIAC AOD dataset was therefore employed to investigate the 10-years trend as well as seasonal and monthly patterns of particulate matter in the Cordoba city. The first showed a marked increase of AOD over time, particularly evident in

    Full Text Available Las áreas de humedal ocupan casi el 5 % del territorio de la Patagonia argentina. En la zona extrandina y el desierto patagónico estos ecosistemas son esenciales para sostener numerosas especies de fauna y flora silvestre. Además, los humedales del norte patagónico permiten el desarrollo de comunidades acuáticas complejas y constituyen el hábitat crítico de grupos de organismos como los peces y los anfibios incluidos en listados de conservación prioritaria. Estos ecosistemas tienen un funcionamiento complejo que depende estrechamente de las fluctuaciones de las variables meteorológicas y son por lo tanto muy sensibles a los efectos del cambio climático. En la actualidad el uso de la tierra, la introducción de especies y la interacción de estos aspectos con el cambio climático constituyen las variables de mayor impacto sobre estos ambientes patagónicos. En este trabajo se presenta información geográfica, geomorfológica y climática de un número de humedales del norte de la Patagonia argentina. Por otra parte, se sintetiza información sobre la flora y la distribución de peces y anfibios con el propósito de enfatizar la importancia de estos ambientes en el mantenimiento de la biodiversidad regional.

    This paper describes the communication activities conducted nuclear science and technology in 2012 in the scientific, educational and tourist areas of Cordoba. The first is the Promotion of the realization of scientific research school works to present in science and technology fairs. The public exhibitions fairs consist of projects conducted by students from all levels of the education system. To do this, students have the guidance of Advisory Teachers, researchers and technologists of the local scientific community, which involves training them for a period of approximately six months. During this year the courses were conducted in 37 cities in the interior province, which are the sites of Regional Headquarters, which included the promotion of the realization of school scientific research on the peaceful applications of nuclear technology and / or national nuclear activities. During the meetings, made presentations basing pedagogical and didactic aspects to coordination between teaching of conceptual content and activities practical introduction to nuclear scientific methodology. As a result of this initiative, between the months of June and September was reached more than 3,000 teachers, using the infrastructure of the Ministry of Science and Technology and Internet. As a result, a dozen schools have begun to seek assistance to develop projects related to nuclear power. Other activities under the name of Scientific School Research Incursion through Experiences with Natural Radiation, consisted of the design and realization of simple laboratory experiences in laboratory's schools. The objective was to strengthen the curriculum and promote critical thinking about the risks and benefits of nuclear technologies in relation to exposure to ionizing radiation involving them. As a result it has been observed that these activities contribute to a progressive scientific and technological literacy of students, who build original knowledge for themselves and develop

[Spanish] En esta contribución se da a conocer una nueva localidad fosilífera en la Cantera Los Guanacos del extremo norte de la sierra de Las Higueras, a 10.5 km de la localidad de Salagasta, Precordillera de Mendoza, oeste de Argentina. Se trata de un nivel carbonático lenticular fosilífero intercalado entre la unidad mixta pelítica/ carbonática (transfacies) correlacionable con la base de la Formación Los Azules. Éste se caracteriza por un límite erosional de espesor milimétrico y por una distribución mecánica de bioclastos e intraclastos, por encima del mudstone basal oscuro. La capa bioclástica se interpreta como el depósito de un evento tempestítico acaecido en la plataforma carbonática. Se determinan las microfacies carbonáticas y las asociaciones de macro y microfauna. Se registran y describen los trilobites Mendolaspis salagastensis y especies indeterminadas de Agnostidae, Illaenidae, Leiostegiidae, Encrinuridae, Telephinidae y Trinucleidae. Se reconocieron braquiópodos indeterminados de la familia Obolidae. Los graptolitos son comparables con Levisograptus cf. austrodentatus y en base a la fauna de conodontos se reconoce la Zona de Yangtzeplacognathus crassus de edad darriwiliense temprana (Ordovícico Medio). Se discuten las implicaciones bioestratigráficas de estos registros, que permiten la correlación de estos niveles de la Precordillera de Mendoza con otras regiones de la Precordillera de San Juan, del Noroeste argentino y del mundo. Se brindan además algunas consideraciones paleoambientales surgidas del análisis de estos registros faunísticos y de las microfacies carbonáticas.

    Malignant neoplasm (MN) mortality worldwide ranks among the first four causes of death, in the 1990 decade (1-4). The aim of this work is to study the eight most frequent MN mortality rates, and especially that one caused by oral cancer (OC) in the province of Cordoba, Argentine Republic, in the period between 1975 and 2000, in order to analyze its characteristics and compare with other populations in America and Europe. The data were provided by the provincial and national Health Ministry and Globocan 2000. The highest male rates were those of Slovakia and France, prevailing lung and bronchus tumors; whereas in females the highest rate was that of breast cancer in the United Kingdom and Germany, and lung cancer in the United States. Regarding to OC in the populations under study, Slovakia and France held the highest rates for both sexes, being Cordoba and Argentina among the lowest values, especially in women. Tongue was the most frequent site in Cordoba (43.5%), followed by salivary glands (23.7%). Male prevailed over female and the oldest ages were observed in the period 1995-2000. The mortality rates by MN in all sites increased 6.6% in both sexes, and by OC 77% in women within the period under study in Cordoba. Oral cancer is a serious problem for public health causing great morbidity and mortality, a situation that has not improved in decades. Mortality rates are an important tool towards implementation and planning of health policies and programs for cancer prevention.

    Whereas in our country's scientific and technological development are essentially in the hands of the State, conducting scientific outreach massive level, involve a degree of commitment by the state led to that effect. Responding to this premise, in 2012, took place in Cordoba some outdoors communication actions. This paper describes the main characteristics of them, specifying those aspects related to the spread of national nuclear activities within that framework. From a focus on science popularization and under the names of 'Scientific and Technological Cordoba Tourism' and 'Science and Technology in the popular events of Cordoba', dissemination events were held in places accessible to the public: beaches, rivers and pedestrian areas of the main cities of the province. It was organized by the Direction of Disclosure and Science Education, Ministry of Science and Technology of Cordoba, which called for researchers from participating institutions, among whom were those related to national nuclear activities. Simple experiments were presented, video projections, street and dissertations astronomical observations with discussion on various topics. The objective was to capitalize on the potential attractiveness of some physical and chemical phenomena curious, to summon people who were enjoying their free time. Those responsible for the activities were researchers, in several cases with doctoral level and calling for the release, as well as professionals in educational sciences. Some of the activities involved in the group's visit transcendent opportunity celebrations in the interior provincial, or events with massive public support. In the case of atomic energy the approach used was based on natural radioactivity and radiation. From the point of view of the results obtained, it can be said that the popularization of science and technology has begun to present itself as an alternative learning of citizenship, which has been well received

    The perception of the nuclear energy of journalist of the Cordoba city and of the member of the legislative body of the Province was investigated. In general a high degree of ignorance on nuclear energy and its uses was found. The majority of them considers nuclear energy a great danger for the society and describes it as a potential damage for health and environment. Little is known about medical applications, food irradiation, etc. As a consequence nuclear energy has no priority in journalist and lawmakers agendas. (author)

    Farming practices and the addition of chemical synthetic substances in conventional agroecosystems are detrimental mainly to natural enemies of phytophagous insects, diminishing the natural regulation of pest insects. On the other hand, in organic agriculture, biological processes and care of the environment are favoured, hence an increase in insect biodiversity is predicted in this type of systems. In this work, abundance, richness of insects and proportion of functional groups were compared through a single quantitative sampling of insects in horticultural crop fields, three under organic and three under conventional management practices. Insect species richness, total and for guilds (phytophagous and entomophagous insects) were significantly higher in organic orchards, and also was the abundance of entomophagous insects. Richness and abundance of all insect orders (with exception of Homoptera abundance), were higher in orchards under organic management, being significant the differences for richness of Coleoptera and richness and abundance of Hymenoptera. Similar tendencies were observed in data obtained through sweep net in weeds. These results suggest that organic practices increase the diversity of species, particularly that of natural enemies.

    Objective To establish an epidemiological surveillance of viral herpes encephalitis in major hospitals of Monteria, Cordoba. Methods From September 2009 to December 2011, a descriptive study of cases of viral encephalitis was made in three hospitals in the city of Monteria. Cerebrospinal fluid (CSF) samples from 118 patients were included in the study. Clinical aspects, as well as cytochemical and microbiological analysis (Gram stain and culture) of CSF, were used for selecting the patients. Virus detection was performed by using multiplex nested PCR for Herpes simplex virus 1 and 2, Epstein Barr virus, Cytomegalovirus and Varicella zoster virus. Results Viral DNA of herpesvirus was detected in the CSFs of 30 (25.4 %) participants, as follows: 22 (18.6 %) Herpes simplex 1 and 2 viruses, 4 (3.3 %) Cytomegalovirus and 1 (0.8 %) Varicella zoster virus. Co-infections were observed in 3 patients (2.5 %), 1 case by HSV-VZV and 2 cases by CMV/HSV. The clinical manifestations of the patients included: headache (18.6 %), fever (14.4 %), asthenia (10.1 %), seizures (9.3 %), vomiting (8.4 %), and stiff neck (5.9 %). Thirty percent of the patients also had HIV-AIDS. A case fatality rate of 20 % was observed for the patients. Conclusions This paper shows that herpesvirus is a cause of infection of the CNS in patients from Cordoba. This study contributes to the epidemiology of encephalitis, as well as to patient management.

    Full text: This work shows the fluctuations of indoor radon concentration in some rooms placed inside a Cordoba Factory Complex. The measurements were performed by Victoreen Radon Monitor. The system was shaped to sample single radon concentration values after one hour integration. It utilizes a passive diffusion chamber and a silicon diffused junction detector. A portion of decay products will plate-out onto the detector and emit alpha particles into the depletion region of a diffused junction detector. The alpha energy is deposited in the detector in the form of ionization which generates a charge pulse. Only alpha pulses of an energy level similar Po-218 and Po-214 are detected. The study of the meteorological parameters shows that the daily fluctuations of the radon concentration respond to the transport and dispersion processes of radon gas through the air. Air temperature, wind's direction and speed are found to be fundamentals parameters in the observed time behavior. The meteorological data were obtained by a portable station (Davis Weathe Monitor II). The radon concentration present a maximum value (1850 Bq/m 3 ) at the night and a minimum value (150 Bq/m 3 ) at the day. (author) [es

    Farming practices and the addition of chemical synthetic substances in conventional agroecosystems are detrimental mainly to natural enemies of phytophagous insects, diminishing the natural regulation of pest insects. On the other hand, in organic agriculture, biological processes and care of the environment are favoured, hence an increase in insect biodiversity is predicted in this type of systems. In this work, abundance, richness of insects and proportion of functional groups were compared through a single quantitative sampling of insects in horticultural crop fields, three under organic and three under conventional management practices. Insect species richness, total and for guilds (phytophagous and entomophagous insects) were significantly higher in organic orchards, and also was the abundance of entomophagous insects. Richness and abundance of all insect orders (with exception of Homoptera abundance), were higher in orchards under organic management, being significant the differences for richness of Coleoptera and richness and abundance of Hymenoptera. Similar tendencies were observed in data obtained through sweep net in weeds. These results suggest that organic practices increase the diversity of species, particularly that of natural enemies.

    Full Text Available The study analyzes the migratory waves from Friuli which, from the 1870s up to the post-World War II years, extensively moved towards Argentina, settling in the areas around the cities of Santa Fe, Cordoba, Entre Ríos, Chaco and Buenos Aires, but reaching also regions as far away as Patagonia. The accurate and well diffused net of the Fogolār Furlan, besides its function as friendly society, also provides to the promulgation of ancient traditions and mores among the new generations, transmitting on to them the cultural, linguistic and ethnic memory of the motherland. Epistles, tales, novels and poems form a paideia which is thus constantly being enlivened, eveng among those who assumed Argentinian nationality or were born in the country. Of utmost interest is, therefore, the resulting literary corpus, representing as it does a renewed search for identity in the form of a dialogue with the world, extending itself well beyond the contingency of boundaries and transmitting the universal essence of logos.

    Full Text Available The aerial views by Alfred Guesdon are considered works of special interest due to their quality and beauty. These drawings are a faithful portrait of the great cities of the period, and a mystery in terms of their creation. After reviewing some of the aerial drawings of the mid-19th century, the author considers undocumented hypotheses regarding the relationship of Charles Clifford to the drawings by Guesdon of Spanish cities, and the issues related to their elaboration by means of plans, photographs and hot-air balloons. Some light is shed on this matter thanks to the unpublished drawing of the city of Cordoba (1853, whose accuracy is evident when compared to a city plan drawn by Montis (1851. A journey through the city of Cordoba and its landmarks proves the documentary value of the drawing by Guesdon, who knew how to combine traditional drawing skills with the latest technical advances of his time.

    The Cordoba department of Colombia programmed to establish 200000 ha of forest plantations by year 2025. Teak was priorized by its adaptation, wood quality and value in the asian markets. The objective of this research was to estimate the expected genetic gain, of phenotypically selected pluss trees in 5316 ha plantation in Cordoba, for diameter at breast height, commercial height, commercial volume and log quality traits. The selection based on the pheno typical evaluation of the tree candidate and its four best neighbors within a 20 m radius, qualifying, individually the first four segments of 2.5 m length. Selected trees were classified in list A as determined to be superior in both, volume and quality, according to the selection differential to all its four best neighbors. List B included those plus trees found superior only in commercial volume or in stem quality. Genetic gain was estimated by multiplying selection differential X average narrow sense heritability. We estimated a Selection Index that integrate commercial volume (60%) and stem quality (40%). From 46 selected trees, 18 were classified as plus A. In selecting and cloning the 18 best A plus trees, based on the Selection Index, we expected genetic gains of 5.52% (diameter); 17.50% (height); 41.71% (commercial volume) and 9,59% (stem quality). These results suggest an important genetic progress breeding teak in Cordoba, as long as they broaden the genetic base of the program and verify results with genetic testing in various potential production areas.

    2013-12-01

    Full Text Available We studied the morphology and size of erythrocytes of H. cordobae, and analysed the geographic variation of this character along the distribution of the species, in relation to the latitudinal and altitudinal distances. Erythrocyte shape of the H. cordobae is ellipsoidal and the nuclei are also ellipsoidal and centrally oriented. Erythrocyte and nuclear size showed significant differences among populations, with the highest mean size corresponding to the population of Achiras (low altitude site and the lowest mean size to Los Linderos (high altitude site. There was no significant relationship between the latitude of each population and the both erythrocyte and nuclear size. The altitudinal variation in erythrocyte cell size may be attributable to the surface available for gas exchange; a small erythrocyte offers a possibility of greater rate of exchange than a larger one. Our results are consistent with studies of other amphibians, where intraspecific comparisons of populations at different altitudes show that individuals at higher altitudes are characterized by smaller erythrocytes.

    2003-11-01

    This thesis is concerned with the acoustic analysis of ecclesiastical spaces, and the subsequent implementation of acoustic design methodology in architectural renovations. One begins with an adequate architectural design of specific elements (shape, materials, and textures), with the intention of elimination of acoustic deficiencies that are common in such spaces. These are those deficiencies that impair good speech intelligibility and good musical audibility. The investigation is limited to churches in the province of Cordoba and to churches built after the reconquest of Spain (1236) and up until the 18th century. Selected churches are those that have undergone architectural renovations to adapt them to new uses or to make them more suitable for liturgical use. The thesis attempts to summarize the acoustic analyses and the acoustical solutions that have been implemented. The results are presented in a manner that should be useful for the adoption of a model for the functional renovation of ecclesiastical spaces. Such would allow those involved in architectural projects to specify the nature of the sound, even though somewhat intangible, within the ecclesiastical space.

    Hourly global irradiations on tilted planes are required for dimensioning PV systems. However, for most sites, only global irradiations on a horizontal plane are available, and, given that to calculate the global irradiation on inclined planes the first step is to determine the diffuse component and this is not collected, we have studied the behaviour of the diffuse component on an hourly basis. Most parametrization models for the derivation of hourly diffuse irradiance from hourly global irradiance involve the clearness index, a parameter that implicitly includes solar altitude. The present paper has focused on the possibility of also including ''mean solar altitude anti {alpha}'' explicitly as a parameter in addition to the clearness index. Several analytical models are proposed, validated and compared here, using solar data collected on our station located in Cordoba (Spain). (author)

    We studied the effect of estimated PM 10 on respiratory infections in children from Cordoba, Argentine as well as the influence of weather factors, socio-economic conditions and education. We analyzed upper and lower respiratory infections and applied a time-series analysis with a quasi-Poisson distribution link function. To control for seasonally varying factors we fitted cubic smoothing splines of date. We also examined community-specific parameters and differences in susceptibility by sex. We found a significant association between particles and respiratory infections. This relationship was affected by mean temperature, atmospheric pressure and wind speed. These effects were stronger in fall, winter and spring for upper respiratory infections while for lower respiratory infections the association was significant only during spring. Low socio-economic conditions and low education levels increased the risk of respiratory infections. These findings add useful information to understand the influence of airborne particles on children health in developing countries. - Highlights: ► Few information is available on children respiratory health from developing countries. ► We modeled the association between PM 10 and children's respiratory infections. ► We checked the influence of weather factors, socio-economic conditions, education and sex. ► Temperature, pressure and wind speed modified the effect of particles. ► Low socio-economic conditions and low education levels increased the risk of infections. - The concentration of airborne particles as well as low socio-economic conditions and low education levels are significant risk factors for upper and lower respiratory infections in children from Cordoba, Argentine.

    The soil vulnerability determines the sensitivity of the soil after an accidental radioactive contamination due to Cs-137 and Sr-90. The Departamento de Impacto Ambiental de la Energia of CIEMAT is carrying out an assessment of the radiological vulnerability of the different Spanish soils found on the Iberian Peninsula. This requires the knowledge of the soil properties for the various types of existing soils. In order to achieve this aim, a bibliographical compilation of soil profiles has been made to characterize the different soil types and create a database of their properties. Depending on the year of publication and the type of documentary source, the information compiled from the available bibliography is very heterogeneous. Therefore, an important effort has been made to normalize and process the information prior to its incorporation to the database. This volume presents the criteria applied to normalize and process the data as well as the soil properties of the various soil types belonging to the provinces of Jaen, Cordoba, Sevilla and Huelva of the Comunidad Autonoma de Andalucia.

    In Colombia, undifferentiated tropical febrile illness (UTFI) are frequent and of considerable concern. They also share many clinical features. Between 2012 and 2013 in an endemic tropical area of Cordoba, Colombia, we conducted a prospective study to establish an etiological diagnosis of UTFI. Using diagnostic tests for dengue, leptospirosis, hantavirus, malaria, rickettsia, brucellosis, hepatitis A and B on 100 patients recruited for the study. We identified 69 patients with presumed UTFI: leptospirosis (n=27), dengue (n=26), hantavirus infection (n=4), malaria (n=4), rickettsial infection (n=2), hepatitis A (n=1), and brucellosis (n=1); no hepatitis B cases were detected. Co-infections with malaria and leptospirosis (n=1), hepatitis A and dengue (n=1), hantavirus and dengue (n=1), hantavirus, dengue, and leptospirosis (n=1) were also identified. No etiologic agent was identified for 31 patients. We conclude that other etiologic agents besides dengue virus deserve greater attention by physicians and public health authorities in tropical area of Colombia.

  20. Safety regulation of geological disposal of radioactive waste: progress since Cordoba and remaining challenges

    International Nuclear Information System (INIS)

    Duncan, A.; Pescatore, C.

    2010-01-01

    Claudio Pescatore, Deputy Division Head (NEA) presented a paper, the purpose of which was to recall where we stood at the time of the Cordoba Workshop (1997) on the regulation of disposal of long-lived radioactive waste, to review developments since then, to present the key existing issues, and reflect on the remaining challenges and possible responses. The overview study on progress in regulation for geological disposal since the Cordoba workshop [NEA/RWMC/RF(2008)6], provides a good list of references regarding the first two issues. The presentation of the existing issues takes advantage of the synthesis of the responses to a questionnaire completed by the regulatory organisations in preparation for this workshop. It warns regulators and implementers that international work to date seems to have created an expectation in the mind of the public and in some organisations that nothing less than a guarantee by the regulator is needed of maintaining current levels of protection of both individuals and populations practically forever, regardless of the impracticality of this. This expectation needs to be replaced with a carefully and clearly explained understanding of the choices involved in dealing with long-lived radioactive waste against a background of our responsibilities to both current and future generations and our practical capacity to deliver them. Concerning the current major challenges faced in regulation, the paper comes back to the issue of the 'guarantee' by the regulator and it observes that there is no doubt that there is a willingness to do the best to comply with the principle of protection and that we are broadly convinced that current concepts for geological disposal, supported by multiple lines of reasoning and application of best available techniques (BAT) will meet that principle. However, we do not have the capacity to prove or guarantee this, nor do we believe that it is possible in practice. Although we are advised that it is neither

    Before the start up of the RA-0 'zero power' nuclear reactor installed at Cordoba National University, it was necessary to send to the Regulatory Authority the mandatory documentation which is required in the licensing process. With the previous papers existing for the operation in the first years of the '70, a work program for the future operational training personnel was elaborated. Based on the Authority's applicable rules and the recommendations and with particular criteria originated in the working university conditions, the SAFETY report of RA-0 nuclear reactor was prepared. This paper describes the principal contents, items and documents involved in the safety report. (Author) [es

    This work includes the completion of a proposed zoning of the Zona de Reserva Forestal del Pacifico (ZRFP) in jurisdiction of the department of Cordoba, which has allowed to establish the managing trends of the natural resources that have been implemented in the municipalities of Tierralta and Valencia, where the uses of the territory have opposite characteristics with the reason of being of these lands, that were originally mainly forest areas and reserves for providing useful wood resources, as well as protective areas, that might reach in the growth of the economy of the country. The offers of zoning use of the soils by vocation and occupation proposed by the Instituto Geografico Agustin Codazzi IGAC (2002) were analyzed in detail; these are the technical foundation for the subtractions, according to the Law 2 of 1959. The work of biotic characterization focuses in the forest refuges that shelter great biodiversity wealth for the region and the department. The results of the characterization and evaluation show that there is a significant deterioration of ecosystems and ecological communities of the territory because of multiple actions performed by man along history, which, besides exploiting the environmental offer, contravene in some extensions the natural vocation of the soils. Therefore, it's important to put in consideration that given the intensity of the width and lengthwise interventions realized in the ZRFP, nowadays only some areas of natural forest remain, especially in the buffer area of the Paramillo National Park and in mountain areas bordering the department of Antioquia, which demands immediate actions of preservation and restoration.

    Triatoma infestans is the main vector of Chagas' disease in South America between latitudes 10°S and 46°S. A multilocus microsatellite data set of 836 individuals from 27 populations of T. infestans, from all its range of distribution in Argentina, was analyzed. Our results favor the hypothesis of two independent migration events of colonization in Argentina and secondary contacts. The majority of the populations of the western provinces of Catamarca, La Rioja, San Juan and the west of Cordoba province, had almost no shared ancestry with the rest of the populations analyzed. Probably those populations, belonging to localities close to the Andean region, could have been established by the dispersal line of T. infestans that would have arrived to Argentina through the Andes, whereas most of the rest of the populations analyzed may have derived from the dispersal line of T. infestans in non-Andean lowlands. Among them, those from the provinces of Formosa, Chaco, Santiago del Estero and Santa Fe shared different percentages of ancestry and presented lower degree of genetic differentiation. The migratory movement linked to regional economies and possibly associated with passive dispersal, would allow a higher genetic exchange among these populations of T. infestans. This study, using microsatellite markers, provides a new approach for evaluating the validity of the different hypotheses concerning the evolutionary history of this species. Two major lineages of T. infestans, an Andean and non-Andean, are suggested.

    Obesity is a chronic, heterogeneous, multifactorial disease, which has sharply increased in prevalence in both developed and developing countries. This study aimed to estimate the prevalence of obesity and to identify socio-demographic risk factors associated with it, with special emphasis on diet. Nutritional status, demographic characteristics, lifestyle habits, and food consumption patterns derived from a Food Frequency Questionnaire were investigated. Exhaustive exploratory analyses were performed in order to describe dietary patterns, and logistic regression models were used for odds ratio estimation. The study included 4328 subjects, over 18 years old and resident in Cordoba city. The prevalence of overweight and obesity was 34 and 17 %, respectively, with 60 % in men and 45 % in women of BMI ≥ 25. Obesity risk factors were high intake of sodium, refined grains, starchy vegetables, and snacks. A lower risk of overweight and obesity was associated with an adequate, moderate intake of meats, eggs, alcoholic beverages, sugar and sweets, milk, yogurt, and pulses. A high intake of snacks, refined grains, starchy vegetables and sodium and low intake of yogurt, milk, pulses, and whole grains seem to be associated with the emergence and high prevalence of obesity in Cordoba, Argentina.

    Full Text Available This paper is aimed at studying the relationship between large rural estates (haciendas and encomiendas in northern Argentina (Jujuy and the establishment of order in the countryside by te State in the second half of the nineteenth century. Even though encomiendas had been abolished in Argentina by Republican legislation at the beginning of that century, an interesting and anachronistic debate developped in Jujuy on the continuity of encomienda and the rights it bestowed upon land ownership. This debate was resolved by the Federal Justice which gave to the provincial State the chance of exerting its control on vast rural areas as well as benefitting from the eventual sale of fiscal lands. The State’s policies favoured the reconstitution of haciendas and, with few exceptions, hindered the peasants’ access to land ownership.

    El presente trabajo estudia la relación entre la hacienda y la encomienda en el norte argentino (Jujuy y el establecimiento del orden rural por parte del estado en la segunda mitad del siglo XIX. Si bien las encomiendas habían sido abolidas en Argentina por la legislación republicana a comienzos de ese siglo, en Jujuy se dio un interesante y anacrónico debate sobre la continuidad de la encomienda y los derechos que otorgaba a la propiedad de la tierra. Este debate fue resuelto por la justicia federal, que abrió la posibilidad al Estado provincial de ejercer su autoridad sobre vastas regiones rurales y, eventualmente, obtener recursos de la venta de tierras fiscales. La política estatal benefició la reconstitución de las haciendas y, con escasas excepciones, frenó el acceso de los campesinos a la propiedad de la tierra.

    Full Text Available Workplace violence occurs in different types: mobbing, sexual harassment, physical and psychological aggression and discrimination. Research shows that health workers are victims of 25 per cent of the reported cases of workplace violence. In Argentina, the dimension of the problem is little known; therefore, the objective of the present study is to determine the frequency of violence against health workers. A cross-sectional study was designed and a random sample selected; a survey was administered to 336 workers in health facilities in Cordoba. 21.2 per cent of respondents reported having experienced mobbing; 6.2 per cent experienced sexual harassment, while 8.7 per cent and 28.3 per cent suffered physical violence and psychological aggression, respectively. The following conclusions were reached: different types of violence are often present in the centers studied, little investigation has been carried out and the health workers responded that they feel unprotected.

    Full Text Available It is estimated that approximately 80% of all trips made in a city have their origin or destination in the home. Therefore, knowledge of the generation of this type of travel is important to move towards a sustainable urban mobility. The paper considers two different environments with their models and rates of generation: low-density residential facilities, con-sisting of isolated houses and with little access to public transport, and apartments with high density, better access to public transport and more diverse use of the soil. Based on the study of 9 cases in the city of Cordoba, Argentina, it has been characterized the generation of travel by car and on foot, obtaining important differences between the two environments studied.

    In this study, we have analyzed the presence of conidia belonging to different species of the genus Alternaria in the atmosphere of the city of Cordoba, using a Hirst sampler. The results show that spores of this genus are present all year, with a clear seasonal pattern which shows two peaks, one in spring and the other in fall. A total of 26,822 conidia/m3 have been sampled, which implies a daily mean of 74.3 conidia/m3. Statistical analyses comparing the data with meteorological parameters show a positive correlation with maximum, minimum and mean temperatures, and a negative correlation with rain. Nevertheless, meteorological parameters seem to affect the number of conidia differently according to the season of the year. Regression analyses carried out in order to obtain a predictive pattern show that the best fit is between the 7-day running mean of the number of conidia and a week's accumulated mean temperature.

    Epidemiological investigations regarding temperature influence on human health have focused on mortality rather than morbidity. In addition, most information comes from developed countries despite the increasing evidence that climate change will have devastating impacts on disadvantaged populations living in developing countries. In the present study, we assessed the impact of daily temperature range on upper and lower respiratory infections in Cordoba, Argentina, and explored the effect modification of socio-economic factors and influence of airborne particles We found that temperature range is a strong risk factor for admissions due to both upper and lower respiratory infections, particularly in elderly individuals, and that these effects are more pronounced in sub-populations with low education level or in poor living conditions. These results indicate that socio-economic factors are strong modifiers of the association between temperature variability and respiratory morbidity, thus they should be considered in risk assessments. - Highlights: • Daily temperature range is a strong risk factor for respiratory infections. • Low education level and poor living conditions are strong modifiers of this relationship. • In Cordoba city higher risk for respiratory infections were observed during summertime. - Daily temperature range is a strong risk factor for respiratory infections, particularly for populations with low educational level or poor living conditions.

    The basin of the El Barreal stream is a dominantly rural area in which groundwater is used for all activities whereas the stream is used as sink of residues and effluents. The existence of a tannery, which discharge the effluents into a wetland (which is drained by the stream), reveals the need to study the presence of Chromium in surface and groundwater and to compare values derived from pollution with those corresponding to the natural water baseline values. Fifty three samples of surface and groundwater were abstracted and chemical analyses were made, including total Chromium in water and plants. The chemical analysis results were studied by means of conventional and statistical techniques. The local and regional geological characteristics allow us to interpret that Chromium in water is derived from source minerals, being possible to stand out that high values probably are related to nearby serpentinite bodies.The values of total chrome in surface and groundwater are included in the natural quality baseline range calculated for this basin (0,25-5ug/L), exempting those samples with higher values linked to sites with farming activities and to the wetland environment where the Chromium effluent is discharged. In the last place, Chromium was retained in soil and plants whereas the aquifer was affected by a contaminant plume of total dissolved solids because of advective-dispersive transport. In the 2009 monitoring survey, a small increase of Chromium in groundwater was detected in relation to that of 2005, being assumed that partial desorption of Chromium is taking place from the solid phase.

    The soil vulnerability determines the sensitivity of the soil after an accidental radioactive contamination due to Cs-137 and Sr-90. The Department de Impacto Ambiental de la Energia of CIEMAT is carrying out an assessment of the radiological vulnerability of the different Spanish soils found on the Iberian Peninsula. This requires the knowledge of the soil properties for the various types of existing soils. In order to achieve this aim, a bibliographical compilation of soil profiles has been made to characterize the different soil types and create a database of their properties. Depending on the year of publication and the type of documentary source, the information compiled from the available bibliography is very heterogeneous. Therefore, an important effort has been made to normalize and process the information prior to its incorporation to the database. This volume presents the criteria applied to normalize and process the data as well as the soil properties of the various soil types belonging to the provinces of Jaen, Cordoba, Sevilla and Huelva of the Comunidad Autonoma de Andalucia.

    Due to low population density, total air pollutant emissions in Argentina are still low if compared with highly industrialised countries. Although a significant deterioration of air quality has been observed for a long time, air monitoring did not begin until the 90's and only in a few cities. The use of air pollution biomonitors represents an important contribution to Argentina, as measurements of air pollutants in large areas would require especial technical equipment not easily available and operated. In this project, two lichen species (Ramalina ecklonii (Spreng) Mey and Flot and Usnea amblyoclada (Muell. Rg.) Zahlbr.) and a Bromeliaceae (Tillandsia capillaris) are used as biomonitors of air pollution at a 50, 000 km 2 area in Cordoba province (central Argentina). AAS and INAA have been applied for the analysis of samples, determining As, Ba, Br, Ce, Co, Cr, Cs, Cu, Eu, Fe, Hf, Gd, K, La, Lu, Mn, Na, Ni, Pb, Rb, Sb, Sc, Sm, Ta, Tb, Th, U, Yb and Zn. The following physiological parameters were also determined: chlorophyll a, chloropyll b, phaeophytin a, phaeophytin b, hydroperoxy conjugated dienes, malonaldehide and sulphur. Some of these parameters were used for calculating a pollution index. These determinations were carried out on pools collected at the sampling sites. AAS and physiological parameters were also applied to the analysis of five-replicate samples in order to study variability sources. For data evaluation, different statistical and other evaluating tools were used: descriptive statistics and Spearman's correlation analysis were used on data from the three biomonitor species while factor analysis and mapping, only for R. ecklonii results.

    The study and monitoring of factors that cause shoreline erosion processes require the use of geographic information systems (GIS) to integrate and analyze data on different topics and with various formats. The scope of this project was to design and build a GIS for the study of erosion processes along the coastline of Cordoba Department, Colombia. In this article, we present some of the tools used for the SIG design and implementation, as well as a specific application for shoreline erosion analysis. The Geo database diagrammed tool (ArcGISa) was used to document the geo database structure. The process is semiautomatic and delivers a comprehensive and friendly format for the end users. Linear referencing and dynamic segmentation tools (ArcGISa) were used to characterize the coastline according to several criteria, without subdividing or duplicating it. Shoreline retreat between 1938 and 2004 was analyzed with OSAS (Digital shoreline analysis system, USGS). Maximum distance between both shorelines was recorded by a Punta Arboletes transect (972 m). Real (on the ground) maximum distance however, was larger (around 1.5 km). Nevertheless it was not recorded by any of the OSAS generated transect

    Full Text Available Los miembros del equipo de cooperación internacional "Territorio Andaluz, Desarrollo e Innovación" se han implicado durante más de una década en proyectos de desarrollo sobre zonas colindantes con el Estrecho de Gibraltar. En este artículo se resume el perfil y las conclusiones obtenidas en los proyectos de cooperación desarrollados por el grupo, así como otros hechos relacionados con las transformaciones territoriales del Norte de Marruecos. En la actualidad, las acciones se basan en la construcción de grandes puertos y carreteras cercanas a los nuevos centros turísticos de la costa. Los impactos son evidentes en el medio ambiente y en el contexto social. La transformación radical ha aumentado el atractivo en las zonas urbanas, incrementando el éxodo rural que ya era de por sí considerable. Por otra, la pérdida de calidad de vida la asociamos a la merma de suelo cultivable y el deterioro del medio al poner en cultivo tierras forestales. La agricultura es de subsistencia y como tal está sometida a la supervivencia de las familias en un medio cada vez más desfavorable. Las intervenciones en este medio podrían tomar como ejemplo los patrones que se han aplicado en el entorno rural español en el pasado, cuyo deterioro siguió pautas similares en un período de tiempo más largo.

    Isotopic ages from metamorphic and plutonic rocks of the Atlantic area of North Patagonian basement indicate that the main crustal tectonic events occurred during the late Proterozoic to early Paleozoic times. Rb/Sr and U/Pb data in the 550-470 Ma interval suggest an old tecto-thermal activity during the upper Brazilian Cycle (Rio Doce Orogeny). At regional scale, the comparable Neo proterozoic basement of Ventania and sedimentary for eland cover of Tandilia continues to the Northeast, in the Dom Feliciano Belt. A possible correlation of the North Patagonian basement with igneous-metamorphic relics of Central Argentina (Pampean Ranges of San Luis-Cordoba and at La Pampa province) is also indicated. (author)

    Buyers are lining up for Argentina's two big state-controlled petrochemical groups, Buenos Aires-based Petroquimica General Mosconi (PGM) and Petroquimica Bahia Blance (PBB). However, feedstock supply contracts with government-owned oil group Yacientos Petroliferos Fiscales (YPG) and gas group Gas del Estado hold the key to both sales. Shell Compania Argentina Petroleo SA (CAPSA), Perez Companc, and Global Petroleum have already bought PGM tender documentation. Shell says it will bid for PGM if the feedstock contract with YPF is acceptable. In addition to price and volume, Shell says the length is critical; it wants a 15-year deal, but would settle for 11. YPF initially sought a five-year contract. PGM, which produces 300,000 m.t./year of aromatics, plus oxo alcohols, methanol, and methyl tert-butyl ether, has sales of $150 million/year

El análisis gira en torno a la obra de uno de los médicos higienistas más influyentes, José María Ramos Mejía, deteniéndose especialmente en su libro más famoso: Las multitudes argentinas (1899. La hipótesis principal que recorre el texto es la siguiente: la medicalización de la sociedad, acentuada luego de las epidemias de cólera y fiebre amarilla de mediados del siglo XIX, ofreció a las elites públicas la posibilidad de construir dominios legítimos de intervención estatal. Intromisiones del Estado en la vida privada que, además de ser algo resistidas por la población, entraban en tensión con los principios teóricos del liberalismo que los propios miembros de la elite defendían.

    2007-10-01

    Full Text Available Since the mid 1990’s, health in Argentina has no longer been considered a social function of the State but was transformed into a market commodity. Neoliberal decentralization favored the introduction of corporate methods and incentivized privatization. In practice, this led to self-management for hospitals, deregulation of social services and incorporation of private capital to the public health business. This exploratory study looks at the impact of these reforms in the public health services sector. It analyzes living and working conditions, changes produced in the organization of work and their effect on labor relations and on participation in union, political and social activities by workers at the National Clinical Hospital of Cordoba, Argentina. Data was primarily collected through an interview survey of a convenience sample of 68 workers from the non-teaching staff; this represents 10% of the total professional, administrative and maintenance staff of the hospital. The interviews demonstrate deterioration in income and living conditions. Hospital self-management for these workers led to increased competition, the fragmentation in the work spaces, tension and the distrust between co-workers, as well as increased intensity in the workload of some employees. The profile of these healthcare workers is structured and marked by silence, the resolution of the conflicts by means of individual action in the workplace, and minimal participation in social-political-union or community organizations.

    In 1989, the US Department of Energy (DOE) responded to the need to redirect resources from weapons production to environmental restoration and waste management by establishing the Office of Environmental Management (EM) and delegated to this office the responsibility of cleaning up the US nuclear weapons complex. Now in its eight year, EM's mission has three central facets: (1) to assess, remediate, and monitor contaminated sites and facilities; (2) to store, treat, and dispose of waste from past and current operations; and (3) to develop and implement innovative technologies for environmental cleanup. To this end, EM has established domestic and international cooperative technology development programs, including one with the Republic of Argentina. Cooperating with Argentine scientific institutes and industries meets US cleanup objectives by: (1) identifying and accessing Argentine EM-related technologies, thereby leveraging investments and providing cost-savings; (2) improving access to technical information, scientific expertise, and technologies applicable to EM needs; and (3) fostering the development of innovative environmental technologies by increasing US private sector opportunities in Argentina in EM-related areas

    QUBIC (QU Bolometric Interferometer for Cosmology) is an experimental cosmology project to measure the modes in the polarization of the cosmic background radiation (CBR), the fossil relic that reveals the properties at the Universe 380,000 years after the Planck Era. Discovery of the CBR in 1964 and measurement of tiny temperature anisotropies in 1992 were major breakthroughs in our understanding of the Universe. The next challenge is to measure the polarization of the CBR accurately enough to detect modes that would reveal the existence of primordial gravitational waves produced in the first stages of the Planck Era and probe inflation theory, that assumes an accelerated expansion during the first seconds. The mode signal is however extremely weak and its measurement requires complex instruments. The QUBIC collaboration has developed the concept of interferometric bolometry, that brings together the sensitivity of bolometric detectors with the control of systematic effects provided by interferometry. QUBIC is an international collaboration involving several universities and laboratories in France, Italy, United Kingdom and USA. Recently, Argentina has suggested Alto Chorrillo (Salta), as candidate site for the installation of the experiment, next to the LLAMA site. Here we describe the scientific objectives and the main features of the experiment and we detail the process through which the international collaboration decided to install in Argentina its first module as well as the challenges for our country in this project.

    The basin of the El Barreal stream is a dominantly rural area in which groundwater is used for all activities whereas the stream is used as sink of residues and effluents. The existence of a tannery, which discharge the effluents into a wetland (which is drained by the stream), reveals the need to study the presence of Chromium in surface and groundwater and to compare values derived from pollution with those corresponding to the natural water baseline values. Fifty three samples of surface and groundwater were abstracted and chemical analyses were made, including total Chromium in water and plants. The chemical analysis results were studied by means of conventional and statistical techniques. The local and regional geological characteristics allow us to interpret that Chromium in water is derived from source minerals, being possible to stand out that high values probably are related to nearby serpentinite bodies.The values of total chrome in surface and groundwater are included in the natural quality baseline range calculated for this basin (0,25-5ug/L), exempting those samples with higher values linked to sites with farming activities and to the wetland environment where the Chromium effluent is discharged. In the last place, Chromium was retained in soil and plants whereas the aquifer was affected by a contaminant plume of total dissolved solids because of advective-dispersive transport. In the 2009 monitoring survey, a small increase of Chromium in groundwater was detected in relation to that of 2005, being assumed that partial desorption of Chromium is taking place from the solid phase.

  17. History of radiobiology in Argentina

    International Nuclear Information System (INIS)

    Mayo, Jose

    2004-01-01

    Radiobiology is a multidisciplinary science dealing with ionising radiation effects on biological material. The history of Radiobiology begins in Germany and France around 1886. Radiobiology was introduced in Argentina in 1926 at the Institute of Oncology Angel H. Roffo as a biomedical research branch. Later on in 1957 was incorporated at the National Atomic Energy Commission (CNEA) of Argentina as a result of the newly started nuclear activities in Argentina. Prior that time no Radiobiology research existed in Argentina. To fill this need a Project to create new laboratories was elaborated by the CNEA. New laboratories in Radiobiodosimetry, Cellular Radiobiology, Radiopathology, Radiomicrobiology, Genetics and Somatic Effects were created. Human resources on different areas of Radiobiology were formed with the assistance of IAEA. With professional and technical personnel specialized in Radiobiology at the beginning of the 1970 decade, the transference of fundamental and applied research to others laboratories started.

    A survey programme was initiated several years ago with the aim of estimating the incidence of naturally occurring radioactive material (NORM) exposure for workers in the oil and gas industry, gold mining, spas, and a tourist cavern in Argentina. This work presents the procedures, methods employed, and results to date from the survey, including protection and remedial actions recommended when deemed necessary. Radium isotope concentrations measured in some samples were well above the exemption values established by IAEA Standards. Elevated radon levels (above the action level established for workplaces) were detected in the gas facilities, the gold mine, and the tourist cavern. The pertinent authorities and the facilities were informed of the detected values in order to take actions to reduce concentrations. In terms of the spas, almost all values for geothermal waters were below the corresponding guidance levels. Some regulatory aspects for the management of NORM are suggested.

Seis de seus membros ocorrem no Paraguai e na Argentina: B. maculata, Clelia bicolor, C. clelia, C. plumbea, C. quimi, e C. rustica. Historicamente, existiram confusões entre as espécies de maior tamanho (B. maculata, C. clelia, C. plumbea e C. rustica e entre as espécies pequenas (C. bicolor e C. quimi. Todas as espécies, exceto C. rustica, possuem mudanças ontogenéticas na sua coloração. As espécies podem ser diferenciadas através do seu tamanho, cor, espinhos do hemipenis, e número de escamas loreais, supralabiais, e ventrais. A maior parte da diferenciação evolutiva em Boiruna e Clelia parecem ter ocorrido na região anterior da cabeça, pelo que mostram as diferentes proporções das escamas da região loreal. Boiruna maculata é a espécie de maior amplitude ecológica; é encontrada na maioria das formações vegetais existentes ao norte do paralelo 38 no centro da Argentina, ausente apenas na região de sedimentos deltaicos da província de Buenos Aires, Argentina, e nos amplos vales e colinas onduladas do leste do Paraguai. Clelia bicolor é mais comum nos vales dos rios Paraguai e Paraná, e com alguns registros na base dos Andes no norte da Argentina. Clelia clelia distribui-se ao longo do Rio Paraguai e do baixo Paraná, e quase todo o leste do Paraguai. Clelia plumbea aparentemente é parapátrida de C. clelia ao longo do rio Paraná no sudeste do Paraguai e na província de Misiones, Argentina. O extremo leste da distribuição de C. quimi limita-se com o extremo oeste da distribuição de C. bicolor na mesma região sem que, aparentemente, haja superposição. Não existe material de referência que prove a presença de Clelia rustica no Paraguai. Na Argentina, ela é uma espécie encontrada em áreas temperadas; ao norte

El régimen anual muestra un marcado cambio del ciclo anual sobre una transecta noreste-sudoeste que atraviesa RPA. Hacia el noreste el ciclo anual de precipitación presenta los mayores registros, y muestra marcado mínimo invernal junto con máximo estival equinoccial (marzo. Hacia el sudoeste, los registros son menores, con uniforme distribución a lo largo del ciclo anual, presentando mínimos invernales ligeros. La distribución de frecuencia observada de las anomalías de precipitación, para verano e invierno, tienden a mostrar una mayor ocurrencia de frecuencias negativas en el intervalo (-100; 0mm, con una ligera mayor probabilidad de ocurrencia de extremos positivos. Las tendencias de las series del semestre cálido son positivas y significativas hacia el norte, con excepción en la zona centro. Para el semestre frío, las tendencias son positivas y significativas en el norte y sudeste de la RPA. Es posible caracterizar toda la RPA mediante dos índices de precipitación para verano e invierno, respectivamente. Estos índices de precipitación regional no presentan tendencia significativa.

    Non-lethal biological techniques such as blood biomarkers have gained attention due to their value as early signals of anthropic effects of contamination representing significant tools to evaluate ecosystems health. We evaluate and characterize in situ genotoxicity of water samples collected from aquatic ecosystems around a fluorite mine using amphibian frogs Hypsiboas cordobae as bioindicator species complemented with 16 physicochemical parameters. Four stations associated with fluorite mine sampling were sampled: a stream running on granitic rock with natural high fluorite content; two streams both running on metamorphic rock with low fluorite content; and an artificial decantation pond containing sediments produced by fluorite flotation process with high variation in physicochemical parameters. We analyses the blood of tadpoles and adults of H. Cordobae, calculated frequencies of micronuclei, erythrocyte nuclear abnormalities, mitosis, immature and enucleated erythrocytes. Individuals were measured and weighed and body condition was calculated. The results of this study indicate that individuals of decantation pond are exposed to compounds or mixtures which are causing cell damage when compared to those that were collected of stream. Larval stage was more vulnerable than the adult phase and it could be related mainly to the higher exposure time to xenobiotics, which can penetrate easily by skin, mouth and gills; additionally this site offers a reduced availability of food than other sites. Therefore, chronic exposure to pollutants could derive in degenerative and neoplastic diseases in target organs. Moreover these individuals may experience reproductive and behavioral disturbances which could lead to population decline in the long term. Copyright © 2016 Elsevier Inc. All rights reserved.

    The annual cycle, annual and seasonal frequency and geographical distribution of hail in Argentina during the 1960-2008 period are examined. Eight regions covering the whole territory were defined based on the correlation of the mean annual hail frequency between all weather stations. Regions lying between 30° and 40°S as well as those dominated by mountains present the highest hail frequencies in Argentina. The eastern and coastal areas of the country experience hail events mainly during springtime but they may start in late winter and continue through the beginning of summer. Events in western and central Argentina also predominate in spring but the maximum frequencies are observed during summer months. Trends in the annual number of hail events calculated for each region indicate that events in northwestern and northeastern Argentina have been increasing as well as in southern Patagonia. On the other hand, in central Argentina, southern Buenos Aires-La Pampa, northern Buenos Aires-Litoral and northern Patagonia trends are negative and statistically significant in the first two regions, basically by the decrease of events during spring and summer.

    Nuclear activities in Argentina are restarted. After almost two decades of near stagnation, the governments political decision of August 2006 regarding electrical energy production, considered the nuclear option as a valid one to solve the problems of the growing demand of electrical energy. This decision triggered again the activities related to the finalization of the third nuclear power reactor (Atucha-II), now actively progressing, the construction of a prototype of the CAREM integral advanced reactor, the life extension of the Embalse CANDU nuclear power plant (NPP) and the studies for the emplacement of a fourth NPP in an appropriate site. In all those years of near stagnation, there were notable exceptions related to the design and construction of experimental and radioisotope production reactors, led by INVAP, a state-owned industry, which exported its production. The accompanying industries of nuclear fuel elements production also remained active, given the demand of the two active NPPs. Meanwhile, the National Atomic Energy Commission of Argentina continued the efforts on research and development that were at the base of the technological achievements of the nuclear activities in Argentina. Nuclear safety studies associated with Atucha II and Embalse NPPs and radiological safety were also a substantive part of the continued efforts by Nucleo-Electrica de Argentina SA and the Nuclear Regulatory Authority of Argentina

    This paper reports that security is defined in different ways by many international actors. To some, security is tied to the definition of an external threat to borders, as in the case of the NATO countries. To other, security is related to development, as in the case of most Third World countries. but notwithstanding different definitions, all countries recognize that the essence of security is the survival of the nation-state itself. The nuclear programs of Argentina and Brazil are among the oldest, most sophisticated and advanced nuclear programs anywhere in the Third World. The programs have never been explained on the basis of threat perception, and in this regard perhaps they constitute the most atypical form of nuclear proliferation known to date. Not surprisingly, any attempt to explain the rationale for the Brazilian and Argentine nuclear programs based on common issues of threat =merely confuses the issue. Thus, nationalism, the search for national identity and pride, the need to express self-sufficiency and the desire to keep options open in an insecure and evolving world order must all be analyzed to comprehend the likelihood of future types of nuclear proliferation. Meanwhile, the study of the contemporary era of Argentine-Brazilian nuclear rapprochement may provide new insights into the complex reasoning behind the decision of countries to go nuclear

    Argentina is within the denominated "new industrialised countries", with the characteristic of having high contrasts in the urban population, based on service and industry, and in the rural population, based on agriculture and cattle, still the main sources of wealth in the country. The process of globalisation and the need to compete hard in international markets have provoked high unemployment and the transfer of workers from a formal market to an informal one. Legislation on occupational health is old and it is in the process of being updated. The system of prevention, assistance and compensation for accidents at work and for occupational illnesses has changed from being optative for employers, to the compulsory hiring of private insurance companies. The Government keeps the role of supervisor of the system. There are enough professionals in occupational health, hygiene and safety but not occupational nurses. The teaching is given by many universities and professional associations, some of which have an active profile in the occupational health of the country.

We performed a literature search identifying 58 reports accounting for 619 cases, involving 13 provinces, their majority (97.7% from high altitudes, in central mountainous areas and Andean valleys, concentrated in Cordoba (430 cases, Catamarca (73, San Luis (29 and Mendoza (28, the remaining provinces being rarely affected. This distribution does not fit that of animal fascioliasis. Certain aspects (higher prevalence in females in a local survey, although a trend non-significant throughout Argentina but not others (patient's age 3-95 years, mean 37.1 years resemble human endemics in Andean countries, although the lack of intensity studies and surveys in rural areas does not allow for an adequate evaluation. Human infection occurs mainly in January-April, when higher precipitation and temperatures interact with field activities during summer holidays. A second June peak may be related to Easter holidays. The main risk factor appears to be wild watercress ingestion (214 during recreational, weekend outings or holiday activities, explaining numerous family outbreaks involving 63 people and infection far away from their homes.

    Full Text Available La magnitud de la crisis económica Argentina es enorme y difícil saber hasta cuando se extenderá, agravada por una situación política frágil. La actual recesión ha hecho caer la inversión publicitaria a los niveles más bajos de los últimos años. De 1997 al 2001 la circulación de la prensa Argentina cayó en el 36 por ciento. El riesgo en Argentina es la eventual extranjerización de casi todos los medios de comunicación.

    The Achala granitic complex belongs to the Sierras Pampeanas Hercynian belt, located west of the city of Cordoba, Argentina. This complex is very large (about 100 km N-S and 40 km E-W) and is composed of biotite, biotite with muscovite and muscovite with tourmaline granites intruded in amphibolite grade metamorphic rocks, along a main N 20 deg. E structural direction. Numerous uranium mineralizations are located within the granitic massif and tungsten mineralizations are present both in the enclosing metamorphic rocks and in the granite. The geochemistry of the granite has been studied in four test areas (Southern, Copina, Median and Don Vincente). Two test areas (Median and Don Vicente) present clear evidence of hydrothermal alteration: albitization and dequartzification similar to the French 'episyenites', silicification and argillic alteration. Potassic alteration is rare and weakly developed. The two test areas with hydrothermal alteration present a high uranium geochemical background (5-30 ppm). High thorium contents (up to 65 ppm) are essentially observed in the less differentiated granites of the Copina and Median areas. Thorium/uranium ratios are highly variable (1-10). Uranium minerals are related to different environments - (1) apatite-biotite enclave mineralized with uraninite and uranothorite, (2) gneiss from the contact metamorphism rim, (3) granite with incipient dequartzification, (4) granite associated with albitic episyenites and (5) silicified granite - but are all located in the two test areas presenting clear evidence of hydrothermal alteration. The three petrogenetic events are clearly related to very different mechanisms, separated from each other by several tens of millions of years in the west European Hercynian chain. In the same period the same succession of events leading to uranium deposits is observed in Argentina. 34 refs, 10 figs, 1 tab

    The assessment of baseline levels of atmospheric pollutants and the identification of polluted areas is a complex problem, as pollutant contents at a certain geographical location is usually a combination of contributions from various diverse sources, including long-range transport. Elemental chemical characterization of atmospheric pollutants is thus of great importance and Neutron Activation Analysis has proved to be a powerful technique for multielemental determination of trace elements in biomonitors and aerosols. The general objective of this project is to study the use of biomonitors, specially lichens, for evaluating pollutant levels over a wide geographic area of Argentina and for establishing baseline values and assessing time trends. Two lichen species (Usnea sp. and Ramalina ecklonii (Spreng.) Mey. and Flot) have been identified as suitable monitors of air pollution, with potential regional application at the central area of the country (province of Cordoba) and pilot studies have been initiated to test the practicability of sampling and sample collection. An area of approximately 40,000 km 2 will be covered by a sampling network, using in situ growing lichens. The distribution maps for the two selected species are already drawn and sampling of local soils will also be conducted. Current efforts at the Neutron Activation Analysis laboratory are put on assessing, for the selected lichen species, the influence of sample preparation methods on trace element concentrations. The use of other analytical techniques will allow the evaluation of the bioindicator chemical response and its relationship to different atmospheric quality levels. Source identification and apportionment will be done by statistical fingerprinting of the elemental concentrations, as sources of pollution are characterized by being composed of different mixtures of elements in different proportions. In this way and as a long-term objective, regional maps will be drawn showing the

    Accurate crop production data is fundamental for reducing uncertainly and volatility in the domestic and international agricultural markets. The Agricultural Estimates Department of the Buenos Aires Grain Exchange has worked since 2000 on the estimation of different crop production data. With this information, the Grain Exchange helps different actors of the agricultural chain, such as producers, traders, seed companies, market analyst, policy makers, into their day to day decision making. Since 2015/16 season, the Grain Exchange has worked on the development of a new earth observations-based method to identify winter crop planted area at a regional scale with the aim of improving crop production estimates. The objective of this new methodology is to create a reliable winter crop mask at moderate spatial resolution using Landsat-8 imagery by exploiting bi-temporal differences in the phenological stages of winter crops as compared to other landcover types. In collaboration with the University of Maryland, the map has been validated by photointerpretation of a stratified statistically random sample of independent ground truth data in the four largest producing provinces of Argentina: Buenos Aires, Cordoba, La Pampa, and Santa Fe. In situ measurements were also used to further investigate conditions in the Buenos Aires province. Preliminary results indicate that while there are some avenues for improvement, overall the classification accuracy of the cropland and non-cropland classes are sufficient to improve downstream production estimates. Continuing research will focus on improving the methodology for winter crop mapping exercises on a yearly basis as well as improving the sampling methodology to optimize collection of validation data in the future.

    Emission inventories of ozone precursors are routinely used as input to comprehensive photochemical air quality models. Photochemical model performance and the development of effective control strategies rely on the accuracy and representativeness of an underlying emission inventory. This paper describes the tasks undertaken to compile and evaluate an ozone precursor emission inventory for the El Paso/Ciudad Juarez/Southern Dona Ana region. Point, area and mobile source emission data were obtained from local government agencies and were spatially and temporally allocated to a gridded domain using region-specific demographic and land-cover information. The inventory was then processed using the US Environmental Protection Agency (EPA) recommended Emissions Preprocessor System 2.0 (UAM-EPS 2.0) which generates emissions files compatible with the Urban Airshed Model (UAM). A top-down evaluation of the emission inventory was performed to examine how well the inventory represented ambient pollutant compositions.

    Emission inventories of ozone precursors are routinely used as input to comprehensive photochemical air quality models. Photochemical model performance and the development of effective control strategies rely on the accuracy and representativeness of an underlying emission inventory. This paper describes the tasks undertaken to compile and evaluate an ozone precursor emission inventory for the El Paso/Ciudad Juárez/Southern Doña Ana region. Point, area and mobile source emission data were obtained from local government agencies and were spatially and temporally allocated to a gridded domain using region-specific demographic and land-cover information. The inventory was then processed using the US Environmental Protection Agency (EPA) recommended Emissions Preprocessor System 2.0 (UAM-EPS 2.0) which generates emissions files compatible with the Urban Airshed Model (UAM). A top down evaluation of the emission inventory was performed to examine how well the inventory represented ambient pollutant compositions. The top-down evaluation methodology employed in this study compares emission inventory ratios of non-methane hydrocarbon (NMHC)/nitrogen oxide (NOx) and carbon monoxide (CO)/NOx ratios to corresponding ambient ratios. Detailed NMHC species comparisons were made in order to investigate the relative composition of individual hydrocarbon species in the emission inventory and in the ambient data. The emission inventory compiled during this effort has since been used to model ozone in the Paso del Norte airshed (Emery et al., CAMx modeling of ozone and carbon monoxide in the Paso del Norte airshed.

    In olive oil, sterols constitute the majority of the unsaponifiable fraction. In recent years there has been increased interest in the sterols of olive oil for their health benefits and their importance to virgin olive oil (VOO) quality regulation. Forty-three olive (Olea europaea L.) cultivars from the World Olive Germplasm Bank, IFAPA Centro 'Alameda de Obispo', Cordoba, Spain were studied for their oil sterol composition and total content. The main sterols found in olive oil were β-sitosterol, Δ(5) -avenasterol, campesterol and stigmasterol, most of them showing high variability. Most cultivars showed total sterol contents within the limits established by EU regulations, although 28% of VOOs analysed were outside the limits established for total content and/or for individual sterols. Over the group of cultivars, total sterol contents ranged from 855 to 2185 mg kg(-1) . The high variability observed was due to the genetic component, since other agronomic and technological factors were similar. Because of the high variability, the sterol fraction can be considered as a useful tool to characterize and discriminate monovarietal VOOs. The results can be useful for nutritionists for VOO inclusion in nutrition studies. Furthermore, the variability observed can be applied in olive breeding projects to select the parents of new olive cultivars with an improved sterol fraction. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

  13. The energy sector in Argentina

    2016-01-01

    This article first outlines that Argentina produces an important part of its hydrocarbon consumption and comment various aspects of this production: hydrocarbons are at the heart of the Argentinian energetic model; conventional hydrocarbon reserves are however decreasing; the public operator remains the main actor even though the market is opened to multinational companies. The article then describes the crisis faced by this energetic model: the energy balance is now a burden; the increasing unbalance between production and consumption can be explained by supply-related as well as demand-related factors; authorities must intervene on hydrocarbon prices and subsidize the oil price on the domestic market. It appears that the future for hydrocarbons in Argentina relies on non-conventional hydrocarbons. Bio-fuels, a key sector of the Argentinian economy, are a matter of trade dispute with the EU and the USA. Apart from hydroelectricity (some new projects are planned), renewable energies are very few developed in Argentina. Appendices propose a graph of the distribution of energy consumption among the different sources, a map indicating locations of the main exploited hydrocarbon deposits, a presentation of mechanisms implemented to subsidize hydrocarbon production

A participação espontânea na guerra e a dúvida sobre uma percepção clara por que os homens lutavam têm sido questionadas por historiadores revisionistas. Era consenso geral, entanto, que a guerra era tanto justa como necessária. As questões políticas e sociais da guerra, como o totalitarismo, o racismo e outras formas de opressão, não são ignoradas pelas narrativas ficcionais sobre os combates. As narrativas jornalísticas e os filmes de Hollywood ocupam-se mais em mostrar o combatente como representante de valores americanos.

El comienzo de este proceso estuvo caracterizado por una definición de la función y los objetivos que estas organizaciones deberían desempeñar en estas industrias; así se conformaron dos comportamientos: el sindicalismo tradicional, vinculado a los trabajadores, y el sindicalismo subordinado, enlazado a los inversionistas. La segunda fase, iniciada a principios de los noventa, se ha caracterizado por un reacomodo en las estructuras internas de las organizaciones sindicales locales. En este reacomodo, la fragilidad de algunas organizaciones conformadas ex-profeso para las maquiladoras, como lo muestran los conflictos analizados, ha sido evidente.

    Full Text Available The Ecological Solid Waste Management Act of 2000 or RA 9003 mandates the local government units to take initiatives in managing their daunting problems on ecological solid waste disposal. Consequently, compliance of Camarines Norte, Philippines on this mandate needs assessment to determine the existing solid waste management (SWM strategies, the effectiveness and the possibility of adoption in each municipality. This study utilized the descriptive method using questionnaire as the main tool supplemented by interview. Results showed that the existing SWM strategies with the highest percentages of existence in the twelve (12 municipalities were provision of number of trucks in transporting solid wastes and knowledge on waste segregation conducted at every household/establishment. Varying levels were observed. However, high level of effectiveness is still required for significant impact, seeing that from the six areas assessed only four municipalities were identified to have more and highly effective SWM strategies. Generally, only availability of technology for composting was considered more effective and can be adopted in all municipalities. Better solid waste management may be fully attained through the involvement, political will and commitment of the implementers in the implementation of politically passed resolutions and undertaking of their initiatives that will stimulate active participation of the community. All these measures may bring change in health and environment in the province.

    Full Text Available Purpose: This paper aims to analyze the situation of job satisfaction and organizational commitment in the hospitality sector in Cordoba (Spain, trying to analyze the possible influence or relationship between contractual typology and time dedication to both constructs. Design/methodology/approach: Initial theoretical study of constructs and certain independent variables, design of a field work, approach of a number of assumptions associated with the study variables and application of statistical techniques, which lead, finally, to the main results and conclusions emanating from them. Findings and Originality/value: Contributions and Results: workers under permanent employment relationships have a higher level of organizational commitment, but not in the case of job satisfaction given its cyclical more than global character. Meanwhile, when the employees have a time part-time dedication their commitment is higher, as it allows a better reconciliation of work and family life. Research limitations/implications: To progress in research on these constructs it would be desirable to develop official statistical sources, allowing results which lead to the establishment of labour policies aimed at improving the welfare of workers. Practical implications: Among other programs, systems strategic compensation and performance evaluation can be better focused through knowledge of how the contractual relationships and time commitment of persons to whom they are addressed, influence the satisfaction and commitment of these. Originality/value: The better understanding of the relationships in the field of study of this article, allows hotel managers to adopt measures that encourage satisfaction and commitment of its human resources, through the pursuit of stable labour relations that allow reconciliation of family and working life.

    Coagulase-negative staphylococci (CNS) are a common cause of bovine subclinical mastitis (SCM). The prevalence of CNS species causing SCM identified by genotyping varies among countries. Overall, the antimicrobial resistance in this group of organisms is increasing worldwide; however, little information exists about a CNS species resistant to antibiotics. The aim of the present study was to genotypically characterize CNS at species level and to determine the prevalence and antibiotic resistance profiles of CNS species isolated from bovine SCM in 51 dairy herds located in the central region of the province of Cordoba, Argentina. In this study, we identified 219 CNS isolates at species level by PCR-restriction fragment length polymorphism of the groEL gene. Staphylococcus chromogenes (46.6%) and Staphylococcus haemolyticus (32%) were the most prevalent species. A minimum of three different CNS species were present in 41.2% of the herds. S. chromogenes was isolated from most of the herds (86.3%), whereas S. haemolyticus was isolated from 66.7% of them. The broth microdilution method was used to test in vitro antimicrobial susceptibility. Resistance to a single compound or two related compounds was expressed in 43.8% of the isolates. S. chromogenes and S. haemolyticus showed a very high proportion of isolates resistant to penicillin. Resistance to two or more non-related antimicrobials was found in 30.6% of all CNS. S. haemolyticus exhibited a higher frequency of resistance to two or more non-related antimicrobials than S. chromogenes. Copyright © 2016 Asociación Argentina de Microbiología.

    Full Text Available The invasive kelp Undaria pinnatifida (Phaeophyceae, Laminariales was first reported in Golfo Nuevo in 1992 and since then it has spread widely over more than 170 km, all along the northern Patagonian coast, Argentina. Field observations in the region have indicated the potential role of invertebrate grazers, like the sea urchins Arbacia dufresnii and Pseudechinus magellanicus and the gastropod Tegula patagonica, in controlling algal density. Laboratory experiments were conducted to ascertain whether, and if so, to what extent these grazers actually feed on the algae. The studied sea urchins fed on the alga, whereas the snail scraped off biofouling adhered to its surface. Higher densities of grazers were observed on the kelp during summer and might be attributed to increasing in metabolism with increasing temperature, and degradation of blades and sporophylls, which possibly increase their palatability.El alga invasora Undaria pinnatifida (Phaeophyceae, Laminariales fue reportada por primera vez en Golfo Nuevo en 1992, dispersándose ampliamente a lo largo de 170 km de costa en el norte de la Patagonia, Argentina. Observaciones de campo hechas en los erizos de mar Arbacia dufresnii y Pseudechinus magellanicus y en el gasterópodo Tegula patagonica evidenciaron que son posibles consumidores de Undaria pinnatifida en la población local. Se realizaron experimentos de laboratorio con el objetivo de probar si estos pastoreadores eran capaces de consumir el alga. Los erizos de mar estudiados consumen el alga, mientras que el gasterópodo ramonea los epibiontes presentes sobre su superficie. Altas densidades de ramoneadores fueron encontradas sobre el alga durante el verano y podrían ser atribuidas a un aumento del su metabolismo con el aumento de la temperatura y a la degradación de las láminas y esporofilos, lo cual posiblemente aumente la palatabilidad del alga.

    The Project Characterization of Coal of Norte de Santander, concluded in the second semester of 1986 with the presentation of the 4 final reports of the participant entities: Universidad Nacional de Colombia - Bogota, Universidad Francisco de Paula Santander, Instituto de Investigaciones Technologicas (I.I.T.), and Instituto de Investigaciones geologico Mineras - INGEOMINAS. In each Institution some common aspects were worked - analytic part and other specific topics, that which believes the necessity to develop a study that unified the parts worked jointly with the elaboration of a new chart of data, and it allowed this way to assemble the analytic base with the studies of some technological properties and of benefit. Initially it is made a summary of the most excellent aspects in the Geology, mining and Commercialization of the Coal of the department and later on with reference to all the available analytic information, new data were obtained with base in averages among Institutions, checkups of differing results, correlate and discard of rusty samples. For the chemical and physicochemical analyses, the plastic properties, the petrographic results, the chemical analysis of the ashes, they were made statistical and correlative new treatment discriminating against the different sectors and formations inside the area (the Formation Catatumbo was excepted). For the analyses more used as range indicators and others of quality were carried out three-dimensional graphic that summarize in a visual form the variation of the parameter through the study area and the sectors inside this being obtained the iso-values curves equally. The study of some properties of the coal related with technological processes like coking, liquefaction and of benefit they supplement the analytic characterization being able to obtain several practical conclusions as for the use of these coal and remarking some concrete problems to solve with the objective of improving the quality of the

La hipótesis es que la causa principal de la reducción de la productividad de las plantaciones es la profundidad de suelo y el volumen efectivo aprovechable por las plantas, y no el contenido de nutrientes. El trabajo se realizó entre los 28º 30’ S, en la provincia de Corrientes, hasta los 25º 30’ S, en la provincia de Misiones. Se seleccionaron 31 sitios donde, 1- se tomaron muestras de suelo para determinar nutrientes y densidad aparente, 2- se midieron las variables dasométricas de las plantaciones y se calculó el Índice de Sitio (IS, 3- se tomaron muestras foliares y se analizaron las concentraciones de C, N y P. El análisis estadístico se realizó con INFOSTAT 2.0. Los sitios se asignaron a tres grupos edafoclimáticos: 1 sitios con suelos rojos del Norte, 2 sitios con suelos pedregosos del Norte y, 3 sitios con suelos rojos del Sur. El crecimiento de las plantaciones de P. taeda fue menor (menor IS en los suelos pedregosos, con más nutrientes, una menor profundidad efectiva y un  menor volumen ocupado por la fracción fina. En la zona norte, la mayor oferta de nutrientes en los suelos pedregosos (respecto de los rojos, no resultó en un aumento en la concentración de nutrientes foliares. La menor capacidad de retención de agua y un menor volumen a ser explorado por las raíces de las plantas, constituyeron la principal limitante al crecimiento en los suelos pedregosos. A pesar de las diferencias en precipitación, todos los sitios correspondieron a la misma Zona de Vida Bosque Subtropical húmedo. Entre los suelos rojos profundos, de similar concentración y contenido de nutrientes, la zona Sur resultó la más favorable para el crecimiento (mayor IS.

    The Argentine National Atomic Energy Commission declares under its Environmental policy the commitment to restore those sites where activities concerning Uranium mining were developed. It makes it beyond the scope of the Project of Environmental Restitution of the Uranium Mining (PRAMU from its Spanish abbreviation). The Chemistry of Water and Soil Division at the Environmental Chemistry and Energy Generation Department belonging to the Chemistry Management Office assist the PRAMU on the installation of an hydroxyapatite permeable reactive barrier (PRB) inside the Mining Complex facility placed at Los Gigantes in the Argentine province of Cordoba (in advance named the site). Among the preliminary assessment activities that are being carried out before the installation of the PRB, it has been prepared a monitoring program of surface water and groundwater useful to develop an environmental baseline suitable for the efficiency assessment of the corrective action to be applied. An exploratory campaign was conducted in the site with the aim of establishing a monitoring net of meteorological and hydrological, as well as physical, chemical and biological parameters in matrixes of sediments, water and suspended particulate matter collected on a regular time basis from its surface water and groundwater bodies. The processed results turn into useful environmental information to: a) determine the status of the environmental baseline of the site, b) establish a water quality index (WQI) to manage the natural resource quality according to a rational basis, c) plan experiments related to the design process of a biogenic hydroxyapatite PRB and d) apply chemometric and mechanistic models to forecast the contaminants mobilization through different scenarios and improve the engineering design of the PRB. Once achieved the hydrogeological characterisation of the site and taking into account the originality of the system the following results have been reached: 1) The boundaries of

    In this modern world, Solid Waste Management is very important in maintaining a high quality of life so humans must manage and store waste efficiently and safely. Almost every day each household generates garbage or wastes. People throw things improperly without knowing the consequences. The main objective of the study was to assess the residents' Solid Waste Management. Specifically, it aimed to answer the following questions: What is the profile of the respondents in terms of age, gender, educational attainment, occupation, monthly income, no. of household member; What is the knowledge of the respondents about Natural Environment?; How do respondents disposed garbage from the household?; What is the level of the respondents concern about proper waste management?; What is the willingness of the respondents to participate in proper Solid Waste Management?; What is the attitude of the respondents towards the Solid Waste Management? The said study was conducted at the Municipality of Linamon, which is a 5th class municipality located at the Eastern Gateway to Lanao del Norte, a south western Province of Northern Mindanao in the Philippines. The study was conducted in the 8 barangays of the Municipality of Linamon, namely: Bosque, Larapan, Mago-ong, Napo, Poblacion, Purakan, Robocon, and Samburon. The Municipality has 3 urban barangays and 4 rural barangays. The study revealed that most of the respondents interviewed were housewives.

Este artigo analisa o impacto do projeto do Pacto ABC nas relações bilaterais no segundo governo de Getúlio Vargas. Através da análise de correspondências diplomáticas, artigos de jornais e documentos do senado brasileiro demonstram-se que a proposta do presidente Juan Perón de formação de uma união aduaneira entre Argentina, Brasil e Chile foi apoiada pelos setores varguistas, mas fortemente rechaçada pelos setores opositores contribuindo para a crise do governo brasileiro. Constatou-se também a influência do governo norte-americano no sentido de desenvolver uma intensa campanha propagandística contra o peronismo e apoiar os grupos contrários a aproximação da Argentina, buscando ordenar a América Latina dentro de sua orbita durante a Guerra Fria. Neste contexto, a proposta de integração regional fracassou, provocando profundos abalos nas relações diplomáticas entre os dois países.

    For many years, the evolution of Argentina's healthcare system has been influenced by political and economic instability. Inflation and hyperinflation have led to anarchic development of both health administration systems and hospitals. Critical care grew in a similar manner, resulting in a mix of > 500 critical care units with very different levels of technology and trained personnel. Cost-containment policies have been implemented mainly by health administration systems. Public institutions (university and large provincial and county hospitals) have suffered hard budget cuts that have resulted in a decrease in the quality of care and the loss of trained human resources. Union organizations, which cover the healthcare costs of > 60% of the population, implemented a low reimbursement policy that resulted in low standards of care for critically ill patients. The country's private hospital system is extremely heterogenous, ranging from little, simple institutions with a 20- to 30-bed capacity to great private institutions with international standards of care. Cost-containment efforts have been sporadic and isolated, and statistical data to analyze the results are lacking. In order to formulate a strategy of cost-containment in the near future, accreditation and categorization of critical care units and human resources training are being implemented by health authorities and the Argentine Society of Critical Care Medicine.

    The authors of the present selection of Latin American Psychiatry texts were characterized by a common deep humanistic attitude. These prolific writers were able to establish or extend the scope of the discipline in which they chose to act, questioning the establishment of rigid boundaries within the framework of a rigorous epistemological reflection. Thus the systematizing spirit of Jose Ingenieros' in the context of positivist evolutionism, resulted in the act of founding a discipline that integrated the biological and the social. In the case of Guillermo Vidal his conception of mental health went beyond the biomedical to consider psychotherapies as an emotional commitment, continence and empathic understanding; with regard to César Cabral his formation and extensive clinical practice resulted in a work defined by the inquiring into the theoretical concepts underlying Psychiatry and Clinical Psychology. This brief selection does not exhaust the issues or the level of ideas and discussions of Psychiatry in Argentina, but constitutes a textual corpus representative of a disciplinary conception understood as scientific and humanistic endeavor.

    This paper reports on Argentina's push to privatize and attract more foreign investment to its petroleum sector which continues to gather momentum. The Argentine government plans by year end 1992 to sell unprofitable assets of Yacimientos Petroliferos Fiscales, then sell as much as 50% of the state oil company through an international stock offering. If privatization proceeds as expected, YPF Pres. Jose Estenssoro the, the company's stock will be offered to private investors early in 1993. The company was founded in 1922. By March 1992, Argentina also will begin selling all assets of state owned Gas del Estado (GDE) through an international bidding process expected to take about 18 months

    Full Text Available Resumo Mercados não tradicionais têm se tornado mais proeminentes na agenda externa comercial da Argentina. Isto é particularmente evidente quando se percebe as relações comerciais no Norte da África, Angola, Oriente Médio e Sudeste Asiático. Com base em investigações realizadas, temos observado que as ligações recentes da Argentina com os países da SEA têm uma dupla tendência: após a década de noventa, houve uma diminuição nas iniciativas de dimensão político-diplomática, ao mesmo tempo que um aumento dos fluxos comerciais, especialmente nas exportações argentinas.  No entanto, desde 2010 iniciativas políticas Argentinas nesta região têm florescido nos órgãos públicos - no Congresso, Ministério do Comércio Exterior e recentemente, junto com o chefe do executivo. A crescente participação de países da SEA na estrutura de exportação da Argentina ocorre simultaneamente a uma concentração maior da oferta de exportação. Tal observação nos direciona ao argumento central desse artigo: apesar do discurso político que destaca a intenção da Argentina no fortalecimento das relações Sul-Sul através da diversificação, a concentração da pauta de exportação de produtos de baixo valor acaba reproduzindo um padrão característico do comércio inter-industrial de relações centro-periferia.

    Full Text Available In 2003, the incidence of tuberculosis in Argentina showed an increase compared to 2002. The severe national crisis at the end of the 90s has probably strongly contributed to this situation. The goal of this work was to estimate the extent of the spread of the most predominant Mycobacterium tuberculosis strains and to assess the spread of predominant M. tuberculosis clusters as determined by spoligotyping and IS6110 RFLP. The study involved 590 pulmonary, smear-positive TB cases receiving medical attention at health centers and hospitals in Northern Buenos Aires (NBA suburbs, from October 2001 to December 2002. From a total of 208 clinical isolates belonging to 6 major clusters, 63 (30.2% isolates had identical spoligotyping and IS6110 RFLP pattern. Only 22.2% were shown to have epidemiological connections with another member of their respective cluster. In these major clusters, 30.2% of the 208 TB cases studied by both molecular techniques and contact tracing could be convincingly attributable to a recently acquired infection. This knowledge may be useful to assess the clonal distribution of predominant M. tuberculosis clusters in Argentina, which may make an impact on TB control strategies.La incidencia de la tuberculosis en Argentina mostró en 2003 un incremento en comparación con 2002.

Quatro destes terminais são descritos neste trabalho como espécies novas, uma pertencente ao grupo de P. palluma e outras três ao grupo de P. patagonicus. Realizaram-se quatro análises usando quatro métodos diferentes para codificar binariamente caracteres polimórficos, e um novo método para codificar os caracteres contínuos. A divisão tradicional do gênero em dois grupos não é apoiada pelo presente estudo, o grupo de P. patagonicus é parafilético em parte da análise. O grupo de P. palluma é monofilético e se sustenta por vários caracteres, as árvores de consenso por maioria, de todas as análises, mostraram com exceção de um par de politomías, uma topologia do grupo bem resolvida. Dentro do grupo de P. palluma, encontra-se um subclado formado por espécies distribuídas no norte da Argentina desde o norte da província de San Juan (ao norte dos 30° de latitude. Nesta análise, o P. palluma de El Planchón (Chile, relaciona-se mais com este subclado do norte que com qualquer outra forma de "P. palluma".

    descriptive study from secondary sources is presented, using vital statistics from Cordoba (Argentina, Campinas (Brazil and Medellin (Colombia during three different periods between 1980 and 2005. The following subgroups of external causes are studied: homicides by firearms and other weapons, traffic accidents, and suicides and deaths with unspecified intentions. The data was disaggregated by age and sex, with rates calculated for the medians of the next three census years. RESULTS: The levels for Medellin are significantly higher than those seen in Campinas and Cordoba for all external causes studied. Young men constitute the group with the highest mortality. The levels in Campinas are twice those seen in Cordoba, especially in homicides and traffic accidents, but the suicide rates of Cordoba are double those in Campinas. For Medellin the rates were highest around 1990, unlike the two other cities where the trend grew between 1980 and 2000 and declined between 2001 and 2005. CONCLUSIONS: The availability of quality data on mortality allows comparisons among the populations studied. When comparing mortality from external causes, considerable differences in the levels and trends can be seen, but there are fewer differences observed on the data for age and sex. These data were collected from cities with similarities, as they are all three important university centers with industrial development that has been important for their countries. The results suggest that socioeconomic and demographic factors are insufficient to explain the great differences in the data reported.

Both share similar clinical manifestations, which include chronic productive cough, hemoptysis, dyspnea, fever, weight loss, and night sweats. This study aimed to determine the prevalence of PTB, paragonimiasis, and co-infections in Zamboanga del Norte, Philippines. Methods This study was conducted in selected villages in two municipalities in Zamboanga del Norte. Patients with chronic cough were interviewed, examined, and requested to submit two sputum samples which were processed using Ziehl–Neelsen method to detect acid-fast bacilli (AFB), and NaOH concentration technique for the detection of Paragonimus ova. Results A total of 836 patients submitted sputum samples for examination. Prevalence was 6.7% (2.5–12.7%) for paragonimiasis and 1.9% (0.9–6.3%) for PTB. Co-infection rate was 0.3%, with two identified cases. Positivity rates for males and females were 9.6 and 5.8% for paragonimiasis and 3.4 and 1.2% for PTB. Conclusion Pulmonary tuberculosis and paragonimiasis are co-endemic in Zamboanga del Norte, suggesting the need to integrate surveillance and control efforts. Strengthening local health systems through collaboration between different sectors is recommended for effective disease control. Development of more sensitive diagnostic tests is important for more accurate disease surveillance. PMID:24601907

  14. History of mesquite introduction in Rio Grande do Norte State, Brazil

    Full Text Available The mesquite (Prosopis juliflora (Sw DC was established as a successful action of xerophilous introduction in Brazilian Northeast dry region. Its fruits are used in animal feed and the wood may be used as piles, firewood and charcoal. The species was introduced in 1942, spreading in "low areas" in Rio Grande do Norte, Paraiba, Pernambuco, Bahia and Piauí States. This article aims to elucidate how mesquite was introduced in Rio Grande do Norte State and to understand how it was spread. It was first introduced in Rio Grande do Norte State by the introduction experiments installed at São Miguel farm in the municipality of Angicos. The enthusiasm of technicians and researchers promoted the distribution of pods and seedlings on farms and cities in the state. In addition, there were government incentives to production, distribution and planting the species. This work aims to establish considerations to be used as historical basis on studies about this species and to consider aspects regarding current situation of this culture in Brazilian Northeast.

  18. Regional polyphase deformation of the Eastern Sierras Pampeanas (Argentina Andean foreland): strengths and weaknesses of paleostress inversion

    The Eastern Sierras Pampeanas of central Argentina are composed of a series of basement-cored ranges, located in the Andean foreland c. 600 km east of the Andean Cordillera. Although uplift of the ranges is partly attributed to the regional Neogene evolution (Ramos et al. 2002), many questions remain as to the timing and style of deformation. In fact, the Eastern Sierras Pampeanas show compelling evidence of a long lasting brittle history (spanning the Early Carboniferous to Present time), characterised by several deformation events reflecting different tectonic regimes. Each deformation phase resulted in further strain increments accommodated by reactivation of inherited structures and rheological anisotropies (Martino 2003). In the framework of such a polyphase brittle tectonic evolution affecting highly anisotropic basement rocks, the application of paleostress inversion methods, though powerful, suffers from some shortcomings, such as the likely heterogeneous character of fault slip datasets and the possible reactivation of even highly misoriented structures, and thus requires careful analysis. The challenge is to gather sufficient fault-slip data, to develop a proper understanding of the regional evolution. This is done by the identification of internally consistent fault and fracture subsets (associated to distinct stress states on the basis of their geometric and kinematic compatibility) in order to generate a chronologically-constrained evolutionary conceptual model. Based on large fault-slip datasets collected in the Sierras de Cordoba (Eastern Sierras Pampeanas), reduced stress tensors have been generated and interpreted as part of an evolutionary model by considering the obtained results against: (i) existing K-Ar illite ages of fault gouges in the study area (Bense et al. 2013), (ii) the nature and orientation of pre-existing anisotropies and (iii) the present-day stress field due to the convergence of the Nazca and South America plates (main shortening

  1. Argentina and Brazil: an evolving nuclear relationship

    Redick, J.R.

    1990-01-01

    Argentina and Brazil have Latin America's most advanced nuclear research and power programs. Both nations reject the Non-Proliferation Treaty (NPT), and have not formally embraced the Tlatelolco Treaty creating a regional nuclear-weapon-free zone. Disturbing ambiguities persist regarding certain indigenous nuclear facilities and growing nuclear submarine and missile capabilities. For these, and other reasons, the two nations are widely considered potential nuclear weapon states. However both nations have been active supporters of the International Atomic Energy Agency (IAEA) and have, in recent years, assumed a generally responsible position in regard to their own nuclear export activities (requiring IAEA safeguards). Most important, however, has been the advent of bilateral nuclear cooperation. This paper considers the evolving nuclear relationship in the context of recent and dramatic political change in Argentina and Brazil. It discusses current political and nuclear developments and the prospects for maintaining and expanding present bilateral cooperation into an effective non-proliferation arrangement. (author)

    With the purpose of studying the radioactive fallout present in Argentina from atmospheric nuclear explosions tests that have been conducted recently, an environmental monitoring program, outside the influence of nuclear facilities of Argentina, was undertaken during 1996 and 1997. The levels of Cs-137 and Sr-90 were analysed in samples of air, deposited material (rainwater), milk, an average meal of a standard man and food. During this period, a total of 630 radiochemical analysis were performed on 325 samples of the different matrices described. The concentration levels of the radionuclides analysed in the different environmental matrices are presented and are compared with the values obtained in the environmental monitoring program done during the period 1960-1981.

    In Argentina, vaccines for immuno-preventable diseases are regulated by the national regulatory agency, the Administración Nacional de Medicamentos, Alimentos y Tecnología Médica (the National Administration of Drugs, Food and Medical Devices, or ANMAT) created in 1992 to ensure efficacy and safety of drugs, food and medical devices available in the country, according to Law 16,463 and Decree 150/92. ANMAT has licensed 84 out of 157 vaccines registered in Argentina. Since 1994, ANMAT evaluated, approved and inspected 20 clinical trials with vaccines (1.8% of the 1062 trials approved by the agency since that time). The National System of Pharmaco-vigilance has received 318 communications of eventual adverse post-vaccination events (0.3% of the total). In addition, ANMAT provides support to the National Immunisation Programme. The current procedure is to follow international guidelines in the field, to be prepared for new, rapidly changing scenarios.

    Full Text Available The 200 year anniversary of the foundation of Argentina and the 150th anniversary of Italian unification marks the occasion for an historical analysis of the presence of Italians in Argentina. The article examines the topic from the 1930s until post WW2, comparing immigration in Argentina with other nations including Australia and the US. The position of immigrants in Argentinian social structure is analysed, individualising 3 elements: that foreigners made up 30% of the population; that there was a high concentration of immigrants living in urban areas, and that in big cities foreigners made up 2/3 of the middle and working classes. Secondly, the influence of Italian immigrants on Argentinian politics is examined, in particular the influence on the Partido Socialista and the Partido Radical, and the role of Italians in protest movements and Argentinian civil wars. Finally, the essay seeks to respond to two central questions: why weren't foreigners given the right to citizenship and to vote? What were the effects on the political system?

Logo, se centra em sua percepção em relação ao peronismo, na violência política que caracterizou a primeira metade da década de setenta, no compromisso que assumiu com os direitos humanos na segunda metade e, finalmente, na construção de uma primeira memória, nos anos oitenta, sobre a ditadura que começava a ficar no passado. O caminho assim traçado abre um registro íntimo, individual e em alguns momentos também comunitário, dos anos de violência política, ditadura militar e a transição à democracia

Se procesaron muestras seriadas, fecales y de escobillado anal, mediante técnicas de concentración. Los resultados se analizaron por sexo, intervalo de edad y provincia. Se calcularon la frecuencia de parasitosis (monoparasitosis y parasitosis múltiple, la riqueza de especies y el coeficiente de similitud de Sørensen. Resultados Misiones presentó la mayor frecuencia de niños parasitados y Chubut la menor (82,0% vs. 38,4%; p ˂ 0,01. El número de especies fue mayor en Misiones y Buenos Aires y menor en Chubut y La Pampa. Los varones estuvieron más parasitados que las mujeres solo en Buenos Aires. Las mayores frecuencias se encontraron en los preescolares de Buenos Aires y los escolares de Mendoza y Misiones (p < 0,05. La monoparasitosis fue más frecuente en Chubut (67,9% y las parasitosis múltiples en Formosa (69,2%. Las especies más frecuentes en la mayoría de las provincias fueron Blastocystis sp. y Enterobius vermicularis. De los geohelmintos, Misiones presentó la mayor frecuencia (23,3% y Mendoza la menor (0,6%; no se hallaron en Chubut, La Pampa y Salta. Buenos Aires, Formosa y Misiones presentaron una composición de especies similar, al igual que Chubut y La Pampa. Conclusiones Las frecuencias de parasitosis en Argentina responden al complejo mosaico de variabilidad climática y socioeconómica del país y revelan una tendencia descendente de norte a sur y de este a oeste.

    Treatment of wastewater is to concentrate the original pollution in a by-product: the wastewater sludge or bio-solid. As example, La Golondrina WWTP (Cordoba-spain) promotes the production of 1,3 kg of sludge per m''3 of wastewater, yielding logically a treated water according to laws. Furthermore, the treatment process there applied reduces the levels of nine majority metals (Cu, Fe, Mn, Pb, Cd, Ni, Cr, Zn, Hg) from 2,72 mg/l to 1.42 mg/l in the treated water, generating almost, a sludge agrees with the spanish normative to sludge intended to agricultural use (its main fate). Summarizing, the treatment of wastewater supposes the concentration of the original biodegradable load into the sludge around 340 times, while metals exhibited a different concentration degree for each one (from 10.000 times for Fe, u pto 1-2 times for Cd and Hg). Finally, the concentration degree of a metal in the sludge is mainly led by the removed concentration of metal in the treatment process, and after, by the original concentration of metal in the influent wastewater.

El objetivo del trabajo es determinar, mediante del análisis palinológico de sedimentos lacustres, las comunidades vegetales y el ambiente predominante durante el Holoceno en el NO del Iberá, ya que los humedales representan uno de los ambientes más aptos para la preservación del polen fósil. Las lagunas estudiadas son: San Sebastián y San Juan Poriahú, cuyos sedimentos fueron obtenidos con un sacatestigo "Levingstone square-rod sampler", las muestras fueron procesadas con las técnicas de Faegri e Iversen y datadas con C14. Los diagramas palinológicos se dividieron en zonas utilizando el programa Tilia. El análisis palinológico permite distinguir diversos cambios vegetacionales: desde los 6 140±50 hasta 5 170±100 A.P.; el NO del Iberá se caracterizó por una vegetación palustre-herbácea y una vegetación arbórea característica de ambientes secos. Desde los 5 170±100 hasta 3 460±60 A.P., se produce la disminución en la frecuencia de especies características de ambientes húmedos y la colmatación del cuerpo de agua. Desde los 3 460±60 A.P. en adelante, si bien continúa el predominio de la vegetación herbácea característica de ambientes palustres, el polen arbóreo, indica el comienzo del desarrollo de un bosque higrófilo.

Sin embargo, algunos autores alertan que puede generar degradación de algunas propiedades del suelo, siendo las lombrices de tierra (Annelida: Lumbricina buenas indicadoras por su capacidad de integrar en su respuesta a los manejos el conjunto de factores de estrés. El objetivo de este trabajo fue evaluar el cambio de las comunidades de lombrices de tierra y de algunas propiedades físicas, químicas y fisicoquímicas en suelos con SD en relación a pastizales naturales (PN, en la cuenca Gral. Deheza, Córdoba. Las lombrices de tierra se obtuvieron según el método del programa TSBF. Se observó un aumento de la compactación y una disminución en el contenido de materia orgánica (MO y del pH en los sitios con SD con respecto a los PN. La comunidad de Lumbricina estuvo dominada por lombrices endogeas, claves en los procesos edáficos al modificar tanto aspectos químicos como físicos del suelo. En SD disminuyó la población de Lumbricina de una media de 297 ind m-2 a 70 ind m-2 con respecto a los PN y aumentó la proporción de individuos en diapausa y juveniles. Esto se explica principalmente por la mayor compactación y el menor contenido de MO. El aumento de organismos juveniles y en diapausa también podría estar asociado a la influencia negativa del intenso uso de agrotóxicos. Se concluye que en la región estudiada, los suelos bajo SD estarían comprometidos en el cumplimiento de las «funciones ecosistémicas» que son la base de su calidad. Se plantea el interrogante sobre la sustentabilidad a largo plazo de esta práctica agrícola.No-till has been recognized as a low environmental impact management in relation to other crop systems. However, it has been suggested that no-till may produce degradation of several soil properties. The earthworm (Annelida: Lumbricina community is a good indicator of soil quality, especially because they integrate all possible stress factors. So, the aim of this study was to evaluate the changes on the earthworm community and on several physical, chemical and physicochemical soil properties in soils under no-till in relation to natural grasslands. The study was carried out in Gral. Deheza basin, Córdoba. The earthworms were sampled by means of the TSBF program method. It was observed an increase in compaction and a decrease in organic matter content and in pH values in no-till sites in relation to natural sites. Lumbricina community was dominated by endogeic earthworms. This is especially significant because the key role they play in edaphic processes since they modify both chemical and physical soil properties. It was found a clear decrease in Lumbricina abundance from a mean of 297 ind m-2 in natural sites to 70 ind m-2 in no-till and an increase in juveniles and diapause organisms in no-till in relation to the natural sites. These results were explained mainly by the high compaction and the low organic matter content. Furthermore, the possible negative influence of an intense use of agrotoxics, mainly associated to the increase in the number of juveniles and diapause organisms, is considered. It is concluded that in the studied region, soils would be threatened in relation to the maintaining of ecosystem functions which are the base of soil quality. The question arises about long-term sustainability of this crop system.

    Argentina has one of the highest cigarette smoking rates among both men and women in the Americas and no legislated restrictions on tobacco industry advertising. The tobacco industry has traditionally expanded markets by targeting adolescents and young adults. The objective of this study was to determine whether and how the tobacco industry promotes cigarettes to adolescents in Argentina. We conducted a systematic search of tobacco industry documents available through the internet dated between 1995 and 2004 using standard search terms to identify marketing strategies in Argentina. A selected review of the four leading newspapers and nine magazines with reported high readership among adolescents was completed. The selected print media were searched for tobacco images and these were classified as advertisements if associated with a commercial product or as a story if not. The tobacco industry used market segmentation as a strategy to target Argentinean consumers. British American Tobacco (BAT) undertook a young adult psychographic study and classified them as "progressives", "Jurassics" or "conservatives" and "crudos" or "spoiled brats". BAT marketed Lucky Strike to the "progressives" using Hollywood movies as a vehicle. The tobacco industry also targeted their national brands to the conservatives and linked these brands with "nationalistic values" in advertising campaigns. Philip Morris promoted Marlboro by sponsoring activities directed at young people and they launched the 10 cigarettes packet as a starter vehicle. The tobacco industry used psychographic segmentation of the population and developed advertising strategies focused on youth. Tobacco control researchers and advocates must be able to address these strategies in counter-marketing interventions.

    Full Text Available La contaminación del aire en Paso del Norte es un asunto preocupante. Algunos ciudadanos y organismos no gubernamentales compelen a los gobiernos de México y Estados Unidos a buscar soluciones a este problema binacional. El Acuerdo de La Paz y las instituciones que nacieron junto con el Tratado de Libre Comercio representan esfuerzos para confrontar los problemas ambientales fronterizos; sin embargo, varios factores han impedido alcanzar resultados satisfactorios. La lección es que las instituciones han internalizado el problema a través de “programas de aire” y, por consiguiente, no han arribado a su solución. La modernización ecológica es una alternativa a la gestión ambiental tradicional. En este artículo expongo que en Paso del Norte ocurre un proceso de ecomodernización. Concluyo que aunque la modernización ecológica se presenta en la región, su éxito es limitado.

    Full Text Available While Spain and other European and American countries celebrated the IV Centenario del Descubrimiento de América in 1892, the population at the northern part of México knew about the last apache incursion in Mexican territory and the rebelion of the neighbours of the Temochic little town. Both events will be used to analyze the situation of overarching violence in the North and surge of a feeling of freedom, independence and discontentedness among the authorities which would lead to the 1910 Revolution.

    Mientras España y otros países europeos y americanos celebraban el IV Centenario del Descubrimiento de América, en 1892, los habitantes del norte de México conocieron las noticias de la última incursión apache en territorio mexicano y la sublevación de los vecinos del pequeño poblado de Temochic. Ambos sucesos nos sirven para estudiar la situación de la violencia generalizada en el Norte y el nacimiento de un sentimiento de libertad, independencia y malestar entre las autoridades gubernativas que desembocaría en la revolución de 1910.

    Roberto Carlos Borja Baeza

    2011-02-01

    Full Text Available Since historical times, mass movement processes have taken place in the Mexican territory as a result of its topography, heterogeneous lithology, intense rainfall and the impact of anthropic activity, particularly in mountainous areas such as the Sierra Norte de Puebla. In this region, as a result of extremely high rainfall, a large number of landslides occurred in October 1999. These were mainly slides and flows; they affected economic, structural and environmental aspects and caused the loss of dozens of human lives. Among the various approaches to analysis of this type of hazard, cartography is of considerable importance since it allows the understanding and assessment of spatial distribution, as well as of the interactions of elements of the terrain that determine slope instability. Hence, some studies of landslide hazard cartography have been carried out in Mexico; these have mainly been based on the overlaying, against a background of geographic information systems, of layers of information concerning the parameters that are involved in slope instability. However, there is a tendency for this approach to establish similar degrees of influence for all factors, regardless of specific local conditions. The present aim was to consider the influence of the five most important parameters controlling regional slope instability in the Sierra Norte de Puebla (slope, morphogenesis, relief dissection, deforestation and roads, and to validate the results by means of a recurrence index. Multicriteria analysis has allowed a map of susceptibility to mass movement processes to be produced for the municipality of Tlatlauquitepec.

    2017-11-01

    Full Text Available In this paper we set out a critical reading of the literature on political neoliberal actors in Argentina. We consider that the concentration of these studies in the national level has to do with a definition of neoliberalism as a set of economical and structural macro politics. We propose to define neoliberalism as a technology of government that intends to hegemonize an “enterprise form” in different social spheres, articulating a symbolical framework in a contingent and contentious way. This insight allows analyzing neoliberal identification processes as heterogeneous trajectories with diverse geographic and temporal scopes.

    Full Text Available This article examines the role of religious actors in sexual politics in Argentina. Sexual politics has become a critical battlefield when it comes to the role of religion in the Argentinean liberal-democratic regime, while gender and sexuality have been the main political targets of religious institutions since the 1980s and 1990s. In this context, progressive legislation on gender, sexual, and reproductive rights was passed, including same-sex marriage and the recognition of transgender identities, despite the opposition of the Catholic Church. Paradoxically, abortion remains largely illegal, allowed only in exceptional circumstances.

    Full Text Available This study focuses on the analysis of high-resolution seismic profiles, integrated with sedimentological, echosounder, SRTM and satellite image datasets, of the Brazilian continental shelf adjacent to the Rio Grande do Norte State, NE Brazil. Located in the northeast of Brazil, the State of Rio Grande do Norte is bounded by two main coastal and shelf systems: the eastern coastal-shelf, from the Sagi River to the Touros High, and the northern coastal-shelf, extending from Touros High to Tibau. This shelf represents a modern, highly dynamic mixed carbonate-siliciclastic system characterized by reduced width and shallow depths as compared with other parts of the Brazilian shelf. It has an average width of 40 km, the shelf-break lying at a depth of ~ 60 m. This shelf is subject to the full strength of the westerly South Equatorial current combined with high winds and moderate to high tides and waves. A sharply defined stratigraphic boundary, probably between the Pleistocene and Holocene deposits, is clearly to be observed in the seismic record. Incised-valleys extending from the main river mouths (e.g.the Potengi, Açu, and Apodi to the shelf break dominate the area investigated and may indicate periods of lower sea level.Este estudo está direcionado ao conhecimento da plataforma continental brasileira adjacente ao Estado do Rio Grande do Norte, NE do Brasil, através da analise de perfis sismicos de alta resolução integrados a dados sedimentológicos, batimétricos, SRTM e imagens de satélites.

    The mortality caused by blood neoplasms in Argentina shows great irregularity. This was found to be caused in certain ways by (a) differences in the sexes and ages of the populations studied; (b) differences in available health services; and (c) environmental factors. Thus high rates and clusters of lymphomas and multiple mylomas were observed in zones with arsenical water, for example.In rural districts, the rates are lower, especially among old-aged people.Lower rates of leukemias were also observed among Spaniards compared to Italians (p=0.001) residing in Argentina. Turkish, Syrian, and Lebanese showed higher rates than Argentinians, Spaniards, or Italians.The results of a case-control study are given in which the following were observed: (a) Among the ancestors of cases HSN there are fewer Spaniards (not significant) and Latin-Americans (p=0.03) and more people who were born in Central or Eastern Europe (p=0.01). (b) In case group, there was more frequent contact with animals, especially dogs; and a greater exposure to petroleum and its products, and to insecticides.

    SLR technique is a proved astro-geodetic art with a significant power to contribute to Earth and Space Sciences. Therefore, scientific applications of SLR System are able to perform multiple tasks in the fields of Astrometry, Geodesy and Geophysics. The results we show here were obtained from satellite observations made at SLR 7406 Station of Observatorio Astronómico Félix Aguilar (OAFA) in San Juan, Argentina. The telescope was installed early on 2006, in concordance with an International Cooperation Agreement between Universidad Nacional de San Juan, Argentina and Chinese Academy of Sciences. In this abstract we show the current research being done with ILRS 7406 station: Length of day (LOD) and Angular velocity of Earth Rotation, calculated weekly; Pole Motion. ILRS7406 is daily surveying Pole coordinates x and y; Tracking SLR to GNSS constellations. SLR System contributes to the adjustment and validation of satellite GALILEO, GPS, GLONASS, and BEIDOU orbits. Our station is nowadays member of the new ITRF 2014 frame, and these past years has been one of the 3 highest producing SLR Stations on the ILRS net, composed of about 40 stations distributed all around the world. The obtained results during this first 10 years of experience are useful to enhance the traditional collaboration between OAFA and international services such as ILRS, IERS and NASA.

    Full Text Available In this paper we present reports of Yugoslav teachers who held classes to immigrants in Argentina 1939-1944, organized by the government of Kingdom of Yugoslavia. Teachers’ reports to Yugoslav Embassy in Buenos Aires testify of Kingdom of Yugoslavia efforts to oppose assimilation and promote and strengthen “Yugoslav national unity”. The reports also describe general social circumstances of Yugoslav immigrants, show various details from their everyday life and contain valuable data on numerous political, economic, social and cultural problems of this diaspora in Argentina and their relationship with motherland. We believe that archive materials presented in this paper opens numerous questions which could be topics of separate researches. Some of them could be the following: To which extent the teachers’ reports represented the actual situation and to which they were shaped to match policy and expectations of Kingdom of Yugoslavia? What was the actual influence of teachers to spreading the “national unity” among immigrants? Have their work left trace in Yugoslav diaspora and in which way? Beside all of the open issues, it is certain that teachers’ reports contain valuable data on immigrants’ everyday life, curriculum, schooling conditions, relationship with motherland, etc. [Projekat Ministarstva nauke Republike Srbije, br. 47016: Interdisciplinarno istraživanje kulturnog i jezičkog nasleđa Srbije.

    1977-01-01

    After dealing briefly with the geochemical cycle of uranium in the earth's crust, and indicating the principal conditions under which different types of deposits are formed, the paper goes on to determine the uraniferous are of mainland Argentina (approximately 900000 km 2 ). Since evidence for the presence of uranium and other radioactive elements in many parts of the country has long been available, an attempt was made to systemize the existing information and classify the uraniferous sites so as to determine their temporal, spatial and genetic relationships with the different containing rocks. In addition, a study was made of the factors which contribute to the concentration of uranium in rocks which are accessible to prospecting (litho-stratigraphy, geological history, mettallogenic cycles, etc.). On the basis of these studies and considering the regional geology of Argentina, 21 ''regional environments'' were defined with varying degrees of probability of containing uranium; these environments will be submitted to long-term regional prospecting studies. It was necessary, however, to make a further sub-division into more homogeneous units with more clearly graded levels of priority, with the result that there are 65 ''prospecting units''. Each of these units, in order of priority, will be subjected to systematic prospecting. Exploratory work on a suitable scale will be carried out in the ''uraniferous'' districts of the ''prospecting units''. The main features of Argentine geology relating to the likelihood of uranium occurrences are briefly described, and maps of the large geotechtonic areas and the ''regional environments'' are included.

    Dengue outbreaks have occurred yearly in Argentina since 1998. A number of candidate vaccines have been tested in endemic countries. The most advanced one was licensed in three countries of Latin America for children over 9 years of age. In the present article the benefits and drawbacks of these vaccines as well as the challenges for the implementation of a vaccination strategy in Argentina are discussed. Furthermore, a risk stratification strategy with new criteria and a multidisciplinary vision is suggested as a possible path for the assessment of the pertinence of a vaccination program in areas showing the highest risk of dengue transmission and/or for people at the greatest risk of developing severe dengue. It is also suggested that the definition regarding the status of endemicity should take into account the local realities. Finally, this paper proposes a broad discussion on the evidences, the expected impact and instrumental aspects that would be involved in the incorporation of a dengue vaccine, marketed or in development, into the national immunization program, and especially which subpopulation should be targeted for the immunization strategy to be cost-effective.

    1977-01-01

    The nuclear power program of Argentina for the period 1976-85 is described, as a basis to indicate fuel requirements and the consequent implementation of a national fuel cycle industry. Fuel cycle activities in Argentina were initiated as soon as 1951-2 in the prospection and mining activities through the country. Following this step, yellow-cake production was initiated in plants of limited capacity. National production of uranium concentrate has met requirements up to the present time, and will continue to do so until the Sierra Pintada Industrial Complex starts operation in 1979. Presently, there is a gap in local production of uranium dioxide and fuel elements for the Atucha power station, which are produced abroad using Argentine uranium concentrate. With its background, the argentine program for the installation of nuclear fuel cycle industries is described, and the techno-economical implications considered. Individual projects are reviewed, as well as the present and planned infrastructure needed to support the industrial effort [es

    Summary Introduction Leprosy is a public health problem in Brazil where 31,044 new cases were detected in 2013. Rio Grande do Norte is a small Brazilian state with a rate of leprosy lower than other areas in the same region, for unknown reasons. Objectives We present here a review based on the analysis of a database of registered leprosy cases in Rio Grande do Norte state, comparing leprosy's geographic distribution among municipalities with local socio-economic and public health indicators and with historical documents about human migration in this Brazilian region. Results The current distribution of leprosy in Rio Grande do Norte did not show correlation with socio-economic or public health indicators at the municipal level, but it appears related to economically emerging municipalities 100 years ago, with spread facilitated by railroads and train stations. Drought-related migratory movements which occurred from this state to leprosy endemic areas within the same period may be involved in the introduction of leprosy and with its present distribution within Rio Grande do Norte. Conclusions Leprosy may disseminate slowly, over many decades in certain circumstances, such as in small cities with few cases. This is a very unusual situation currently and a unique opportunity for epidemiologic studies of leprosy as an emerging disease. PMID:26964429

    2015-06-12

    The taxonomy of some ophiuroids reported from off Argentina, western Antarctica and the SW Atlantic Ocean is reviewed. The species Amphilepis sanmatiensis, known only from the small holotype, is a synonym of Amphioplus lucyae. This synonymy removes the only reported endemic ophiuroid from Argentina. The species name "Ophiacantha ingrata Koehler, 1923" used for specimens from South Georgia is invalid; the specimens are likely to belong to one of two cryptic species within the O. vivipara complex. Specimens of Amphiura joubini reported from Argentina are re-identified as Amphiura princeps, and specimens of Ophiactis amator from the Antarctic Peninsula are re-identified as Ophiactis asperula.

    Full Text Available Las comunidades indígenas atacameñas del norte de Chile, ubicadas en una región de frontera con Argentina, han tenido un interesante proceso de construcción de nuevas identidades como respuesta a los fenómenos de la modernización desde la década de los años 50, y posteriormente, ante la globalización, desde la década de los 80 hasta los primeros años del siglo XXI. Estos procesos han sido observados por los autores durante 35 años de trabajo antropológico sobre los cambios socioculturales ocurridos en dichas comunidades indígenas. Los resultados obtenidos permiten exponer una visión crítica y algunas reflexiones sobre la situación actual y las proyecciones a futuro de los atacameños en un mundo global que los ha invadido no solamente por medios de comunicación e información, sino también, por la presencia relevante de diversos agentes sociales públicos y privados, nacionales e internacionales, que han intervenido e intervienen actualmente, sobre sus recursos naturales, sus poblaciones, sus culturas locales y principalmente, sobre sus identidades étnicas. Se analiza la intervención de los antropólogos a partir de las investigaciones arqueológicas del padre Gustave Le Paige, como agentes que pretenden contribuir a la construcción de las identidades atacameñas, el impacto de los movimientos a escala mundial sobre reivindicaciones étnicas desde la década de los 80 con la presencia de ONGs y otros agentes invasores que intentan conducir u orientar sus procesos de resignificación étnica, y los fenómenos de interculturalidad que ha traído la globalización, especialmente, a través de los sistemas educativos. Se plantea finalmente, la necesidad de que los atacameños sean los conductores de los procesos de rescate y reconstrucción de sus identidades culturales en función del control de su futuro desarrollo en un mundo globalizado.

La disponibilidad de frío varía entre regiones y entre años, y puede ser insuficiente para los cerezos. Por lo tanto cuando se desea incorporar el cultivo del cerezo a nuevas regiones se debe conocer previamente la disponibilidad de frío invernal. Los objetivos del presente estudio fueron: desarrollar un pronóstico para estimar la disponibilidad de frío invernal y calcular la probabilidad de satisfacer una determinada demanda de frío del año en curso. Los modelos mostraron que el porcentaje de variabilidad explicado de las unidades de frío Utah modificado en las fechas de referencias (UFUM FR varía entre 50 y 87% para Junín y entre 50 y 86% para San Martín. La probabilidad que posee Junín de alcanzar el valor medio de 884 unidades de frío Utah Modificado (UFUM es 28%, mientras el valor medio de San Martín es 816 UFUM y su probabilidad es 16%. El pronóstico de frío invernal permitirá al productor evaluar los riesgos que posee su plantación de experimentar daños por falta de frío invernal y eventualmente ejecutar medidas correctivas.During the winter rest, fruit trees of temperate zones should be exposed to low temperatures in order to satisfy their chilling requirements. Chill availability varies through regions and years, and this may be insufficient for cherry trees. Therefore, when farmers want to incorporate new areas, they should be acquainted with winter chilling availability beforehand. The objectives of this study were: to develop a prognosis to estimate the amount of winter chilling and to calculate the probability of satisfying the amount of chilling requirement of any given year. Models showed that the proportion explained by modified Utah chill units at reference date (MUCU RD varied between 50 to 87% for Junín and 50 to 86% for San Martín. For Junín, the probability to reach an average value of 884 chill units Utah modified (MUCU is 28%, whereas the average value for San Martín is 816 MUCU and its probability correspond to 16%. The winter chill prognosis will allow the producer evaluates the risks which has its plantation suffer damage due to lack of winter chill and eventually implement corrective measures.

El eje fecundatorio probó ser independiente de estas variables, aunque algunas interacciones aproximaron significación estadística. Se propuso una interpretación psicológica de  los resultados. La mujer norteña desearía más hijos debido a su mayor aceptación de un rol femenino dependiente y mayor disposición a satisfacer el machismo de su marido. La mujer sureña desearía menos hijos debido a su posición más autónoma en la vida familiar y mayores expectativas de participación activa en roles ocupacionales.

    2009-01-01

    14 C is a long half-life radioisotope, which is present in radioactive waste generated during the operation and decommissioning of nuclear power plants. 14 C can also be found in waste generated by medical diagnostic laboratories or any one generated by fields that deal with research and development (mainly connected with the biochemists area). According to international precedents the disposal of 14 C based on the final amount found in radioactive waste and its chemical form have conditioned the design and operation of the facilities (either because of the amount of it or the chemical form in which 14 C was present). We have to take into account that the design of facilities for radioactive waste disposal is included among the obligations of the National Radioactive Waste Management Program (PNGRR). It is absolutely necessary to count with enough information about the characteristics of any waste containing 14 C that is generated in Argentina, in order to be able to fulfil the requirements previously mentioned. The main characteristics of interest in the frame of the present project are: a) the principal reactions that take place for the formation of 14 C; b) The specific concentration of activity in materials where this radio nuclei is formed or is accumulated; c) To know which is the current step in the process of managing these wastes (in Argentina and all over the world). Either if it refers to bulk or conditioned storage, inside the generating facility; d) Transportation possibilities of 14 C under these conditions; e) The accumulated volume and the generation rate of this kind of waste in Argentina. This paper presents an initial collection and evaluation of the information related to the characteristics already mentioned, having gathered published material from the literature and information in the PNGRR up to this moment. The description of the characteristics of the radioactive waste containing 14 C from nuclear power plants, hospitals and research and

    The aim of this study to analyze the properties of ceramic blocks produced by the states of Paraiba and Rio Grande do Norte. For this, the raw materials used in the fabrication of these blocks were characterized using the techniques of chemical, granulometry and mineralogical analysis and determination of the plasticity index of mixture ceramic. The properties of the ceramic blocks were determined by evaluating the geometric and visual characteristics and determining the water absorption and compressive strength, according to technical recommendations ABNT NBR 15270. It can be observed that samples have chemical compositions with a predominance of SiO 2 and Al 2 O 3 and Fe 2 O 3 and they are composed of mica, kaolinite, quartz, feldspar and goethite. It was also noted that all blocks showed compressive strength less than 1.5 MPa. (author)

    Formaggio, A. R. (Principal Investigator)

    1984-01-01

    Pedologic photointerpretative criteria adapted to LANDSAT orbital imagery were used: drainage (pattern, integration degree, density and uniformity degree); relief (pattern, dissection degree and crest lines); photographic texture, photographic tonnality, and the land use (type, glebas size and intensity of use). The performance of the imagery as an auxiliar tool in the soil survey processes, at Rio Grande do Norte State was evaluated. The drainage and relief elements were easily extracted from the imagery and also ones that provided the greatest deductive possibility about pedologic boundaries. Other analyzed criteria were considered only auxiliaries, corroborating some soil limits in the evidences convergence phase. The principal pedologic dominions of the 30,000 sq km are covered by the same LANDSAT image (WRS 359/16) were delimited with good precision: (1) fluvial plains, beaches, dunes and coastal mangroves; (2) North Coast line Plateau; (3) Acu Sandstone Zone; (4) residual plateaus of the Tertiary; and (6) plains of the embasement.

    2000-01-01

    The Guadalupian rocks of the northern Del Norte Mountains were deposited in a foreland basin between land of the Marathon orogen and a carbonate shoal established on the geanticline separating the foreland basin from the Delaware basin. Deposition was alternately influenced by coarse clastic input from the orogen and carbonate shoal, which interrupted shallow basinal siltstone depletion. Relatively deeper-water deposition is characterized by carbonate input from the shoal, and relatively shallow-water deposition is characterized by sandstone input from the orogen. Deposition was in five general transgressive-regressive packages that include (1) the Road Canyon Formation and the first siltstone member and first sandstone member of the Word Formation, (2) the second siltstone member, Appel Ranch Member, and limy sandy siltstone member of the Word Formation, (3) the Vidrio Formation, (4) the lower and part of the middle members of the Altuda Formation, and (5) part of the middle and upper members of the Altuda Formation.

    The application of montmorillonite nano composites has been improved in order to obtain dispersed phase with particles of nano metric dimensions. To obtain these nanoparticles, the clays must pass an effective purification process for removing unwanted materials, which would undermine the processes of intercalation and exfoliation of montmorillonite in a polymer matrix. This study intention to characterize and purify a montmorillonite clay from deposit recently discovered in the city of Parelhas in Rio Grande do Norte, through the separation of coarser materials by decantation followed by a chemical attack that promoted oxidation in samples where it was realized reduction of impurities such as organic matter and other substances that would hinder the achievement of nanoparticles. Under these conditions, the clay is suitable for the work as dispersed phase in a polymer matrix nano composite. The results were demonstrated by analysis of scanning electron microscopy (SEM), chemical analysis, BET and X-ray diffraction (XRD). (author)

    Knight, P.

    1998-01-01

    The first 1,800 km stretch of a 3,400 km natural gas pipeline from Bolivia to Brazil will start operating in December. First planned 50 years ago, the pipeline has long been expected to result in an immediate surge of gas use in Brazil. However, impending deep recession in Brazil makes this prospect less likely despite the power shortages which indicate the need for considerable gas imports. Initially, most Bolivian gas will flow through Brazil to Argentina. But gas production is expanding rapidly in Argentina and the supply contract with Bolivia ends in 1999. Plans are well advanced to build two gas lines into the south of the Brazil from Argentina. Ultimately, it is anticipated that Argentina, which has abundant reserves and a virtually saturated domestic market, will become the principal source of natural gas for Brazil. (UK)

    2018-03-06

    In recent years, there have been calls in activist spaces to 'queer' abortion rights advocacy and to incorporate non-normative notions of gender identity and sexuality into abortion struggles and services. Argentina provides an interesting site in which to examine these developments, since there is a longstanding movement for abortion rights in a context of illegal abortion and a recent ground-breaking Gender Identity Law that recognises key trans rights. In this paper, we analyse public documents from the abortion rights movement's main coalition - the National Campaign for the Right to Legal, Safe and Free Abortion - alongside interviews with 19 Campaign activists to examine shifts and tensions in contemporary abortion rights activism. We trace the incorporation of trans-inclusive language into the newly proposed abortion rights bill and conclude by pointing to contextual factors that may limit or enhance the further queering of abortion rights.

    Full Text Available This is a first approach to the application of virtual reconstruction techniques of a colonial house. In Argentina it is still uncommon to perform 3D modeling of archaeological sites and especially in historical archeology. As a first step, we used the Google SketchUp to model the country house located on the banks of the Río de la Plata (Buenos Aires. It has historical significance because it belonged to a Spanish councilman, housed hundreds of slaves and was the place where stayed the troops that carried out the Second British Invasion of Buenos Aires. In this case, the 3D modeling was useful for evaluating the future excavationa and activities of preservation of cultural heritage.

    In this paper, we identify 37 companies that produce nano-enabled products in Argentina. We locate the products of these firms in terms of both their economic sector and position in a value chain. The research was done through a four-step methodology. Firstly, an inventory of firms was created. Secondly, the firms were classified by their economic sector, following the United Nations economic classification. Thirdly, the firms were located within a simple nanotechnology value chain. Finally, the products were classified according to their final destination, being either means of production or final consumer products. The results show that healthcare, cosmetics, and medicine is the most represented sector along the value chain, followed by electronics.

    The Argentine Atomic Energy Commission promoted and participated in a unique achievement in the R and D system in Argentina: the integration of science technology and production based on a central core of knowledge for the control and management of the nuclear fuel cycle technology. CONUAR SA, as a fuel manufacturer, FAE SA, the manufacturer of Zircaloy tubes, CNEA and now DIOXITEC SA producer of Uranium Dioxide, have been supply, in the last ten years, the amount of products required for about 1300 Tn of equivalent U content in fuels. The most promising changes for the fuel cycle economy is the Slight Enriched Uranium project which begun in Atucha I reactor. In 1997 seventy five fuel assemblies, equivalent to 900 Candu fuel bundles, will complete its irradiation. (author)

    1997-01-01

    The Argentine Nuclear Power Plants (NPP) ATUCHA I (357 Mw, SIEMENS) and EMBALSE (648 Mw, CANDU), both of PHWR type, were owned and operated until August 94 by the Comision Nacional de Energia Atomica (CNEA). Until that date, CNEA, the national agency for nuclear R and D, concentrated three activities or roles: Research, Nuclear Regulations and NPP Operation. Since August 1994 NPP's are owned and operated by a state electrical company (Nucleoelectrica Argentina S.A.) the nuclear utility supplying 15% of the national electrical generation demand. NASA is going to be privatized according to a recent national law regulating nuclear activities. The transition from a research agency to a commercial company requires the introduction of changes in the management of activities. Mention of these changes is limited to those relating to Safety

    Full Text Available O objetivo deste trabalho foi avaliar os impactos ambientais do manejo agroecológico da caatinga, em unidades de produção familiar no Rio Grande do Norte, pelo método Ambitec de produção animal - dimensão ambiental, desenvolvido pela Embrapa Meio Ambiente. Foram avaliadas sete unidades de produção familiar, em quatro projetos de assentamentos de reforma agrária do Município de Apodi, RN. Os dados para o levantamento foram obtidos por meio de questionários aplicados aos representantes das unidades produtivas familiares, que atribuíram, a cada variável estudada, um valor que representou a alteração proporcionada pela implementação da tecnologia. Após a inserção dos coeficientes de alteração de cada variável dos indicadores por unidade de produção, o coeficiente de impacto foi automaticamente calculado por meio da planilha Ambitec. O manejo agroecológico da caatinga resultou num impacto ambiental positivo, e suas maiores contribuições foram relacionadas aos efeitos positivos dos seguintes indicadores: capacidade produtiva do solo, uso de insumos materiais, qualidade do produto e diminuição da emissão de poluentes à atmosfera. Dois indicadores geraram efeitos negativos: o uso de energia e o uso de recursos naturais. Pela superioridade dos benefícios gerados, o manejo agroecológico da caatinga é uma inovação tecnológica geradora de impactos ambientais positivos.The objective of this work was to evaluate the environmental impacts of caatinga agroecological handling, in production unities of family farms, in Rio Grande do Norte, using the method Ambitec of animal production - environmental dimension, developed by Embrapa Meio Ambiente.

    Full Text Available El presente artículo analiza las transformaciones de la política financiera en la Argentina durante el período 1991-2011. Para ello, se estudian las principales acciones del Estado orientadas a enfrentar la problemática de la deuda pública y el financiamiento, así como las relaciones establecidas con el sector financiero y el FMI. La evolución de la política financiera argentina resalta uno de los contrapuntos más sobresalientes entre el período de la convertibilidad vigente hasta 2001 y la etapa posterior. El régimen de convertibilidad implicó el sostenimiento de una moneda nacional sobrevaluada, la cual determinó el progresivo incremento de la deuda pública y alentó el proceso de financiarización de la economía. En cambio, el régimen de la posconvertibilidad, apoyado en el mantenimiento de un tipo de cambio competitivo junto al superávit fiscal y comercial, ha contribuido a promover la actividad productiva por sobre la financiera. Esto, junto a la reestructuración de la deuda, ha permitido sostener un proceso de reducción gradual del endeudamiento público en términos relativos, liberando recursos para fomentar el mercado interno. Consecuentemente, con posterioridad a 2002 se observa una erosión de la capacidad de condicionamiento estructural sobre la dinámica del crecimiento de los acreedores, el FMI, y el sector financiero en general, en simultáneo con la obtención de mayores grados de autonomía financiera por parte del Gobierno Nacional. Finalmente, se analizan los desafíos que impone la crisis internacional a la continuación de este sendero.

  17. 222Rn Measurements in Dwellings of Argentina

    International Nuclear Information System (INIS)

    2011-01-01

    Radon gas ( 222 Rn) is responsible of about fifty per cent of the world population dose due to natural sources, being the most important pathway the inhalation of radon progeny, specially indoors. Radon concentration has been measured in dwellings at different locations in Argentina. The places selected to be evaluated are representative of the different geologic zones of the country. Near 3000 dwellings have been analyzed since 1983 up today. The measuring methods used in this case were track etched detectors, electrets and detectors based on activated charcoal adsorption. Two different methods with track etched detectors were used: a simple one, which determines only the average radon concentration, and a second one that measures both radon concentration and the equilibrium factor (F) between radon and its daughters. The last one is a method that uses two Makrofol passive track detectors in the same device. The average radon concentration value obtained from all the dwellings evaluated was 44.2 Bq.m-3. The annual effective dose calculated from this average concentration, using a dosimetric factor of 25 μSv.a- 1. (Bq.m -3 ) -1 , which assumes an equilibrium factor of 0.4, was 1.11 mSv. The average value obtained from the 222 dwellings evaluated by the second method was 49.3 Bq.m -3 and 0,37 the equilibrium factor, resulting the annual effective dose estimated 1,44 mSv. The measured equilibrium factor of 0,37 allows us to verify the assumed equilibrium factor of 0,4. Finally, radon levels in dwellings of Argentina are within the acceptable values for population, not being necessary to implement remedial actions, except in isolate cases that are still under study.

  18. Republic of Argentina: Argentina is the envy of other Latin American countries.

    Science.gov (United States)

    1984-05-01

    Argentina's economic and political history may appear grim by US standards, but it is envied by many other Latin American nations, and by Latin American standards its demographic situation is enviable as well. A low population growth rate combined with abundant natural resources means that the poverty of its neighbors has not hit Argentina. Almost everyone eats well and the staple is beef -- about 240 pounds per capita per year. Final figures for the 1980 census of population and housing report a total of 27.9 million people, an increase of 17% from the 23.8 million people counted in 1970. The average annual rate of increase was 1.5% a year. With the exception of Uruguay, this is the lowest rate of increase in continental Latin America. The birthrate of 24 births/1000 population is third only to Chile and Uruguay as the lowest in continental Latin America, although the death rate is about average at 9/1000. After several decades of decline, the death rate is rising again because the population is aging. A current problem is the emigration of Argentinians to other countries, a problem that is most severe among highly trained professionals. Over 1/3 of those who leave Argentina come to the US, with Spain and Canada receiving the next highest numbers. At its current growth rate, Argentina's population will double in 46 years. It is estimated that the population was 29.1 million in 1983; it is projected to be 34.5 million by the year 2000 and 39.6 million by 2020. Over 1/3 of the population live in and around Gran Buenos Aires, the largest metropolitan area in South America and among the ten largest in the world. There is a large core of Spanish descendents still living, but some other European countries are well represented also. The 1980 census recorded 7.1 million households; the average number of persons per household was 3.9. There were 8.2 million dwellings counted in 1980, with an average of 3.3 people per dwelling. 13% of all dwellings were unoccupied at the

The purpose of this paper is to sketch the global inteligibility of the regional history of North-West Argentina as related to the National history of Argentina from 1778 to 1914. At first, it analyses the assurance of these provincial Creole societies in the outpost of the developing argentinity: after the Vice-Kingdom of La Plata became autonomous, during the independence war and during the civil war which were calming down after 1852. Then, this work shows how the strengthening of those regional societies, which happened from 1852 to 1888 on the base of an ' Hinterland economy ', almost isolated from that of Buenos Aires but integrated to Northern Chile and Southern Bolivia, precapitalist but mercantile, traditional but expanding itself, achieves the political ideal, seeked after here by the local elite since 1778: that of small provincial Republics, strongly autosufficient, in front of the cosmopolitanism of the harbour metropolis. The situation topples over after 1888 when the direct connection of these provinces to the national and international market (via

    Full Text Available Neste trabalho se analisa e descreve a situação sinótica associada à precipitação e temperatura do território argentino durante o ano de 2003 e o primeiro trimestre de 2004. A escolha deste período obedece à falta de precipitações em pelo menos dez províncias argentinas, o que ocasionou grandes prejuízos econômicos no setor agropecuário. Com o intuito de determinar as causas deste déficit de precipitações foram analisados os campos médios de altura geopotencial nos níveis de 500 e 1000 hPa e suas anomalias. Em 2003, o déficit de precipitação se associa principalmente às anomalias de geopotencial no nível de 500 hPa, que mostram um fluxo dominante de SO que atravessa o país diagonalmente entre 45°S e 30°S. Em 1000 hPa o anticiclone subtropical do Atlântico se encontra enfraquecido, deslocado para o norte e afastado do continente, enquanto que o anticiclone subrtopical do Pacífico está mais intenso e deslocado para leste respeito da sua posição normal. No primeiro trimestre de 2004 a seca se deve principalmente à presença de uma crista no nível de 500 hPa posicionada no centro do país. As anomalias médias de temperatura do período considerado resultam positivas sobre toda a Argentina. Em 2003, essas anomalias se devem à contribuição do fluxo do N-NE desde o norte do país, à subsidência ocasionada pelo anticiclone do Pacífico mais deslocado para o interior do continente e a orografia. No primeiro trimestre de 2004 as anomalias se originam devido ao fluxo do norte e à freqüente circulação anticiclônica no Atlântico ao sul de 35°S.This paper analyzes and describes the synoptic situation associated with precipitation and temperature in Argentina during 2003 and the first quarter of 2004.

    De las obras de arquitectura popular en América, las mexicanas requieren especial consideración, ya que a pesar de la ubicación geográfica de México en América del Norte, su cultura permanece fuertemente arraigada. Esta suerte de independencia en hábitos y ritos se refleja en la arquitectura mexicana vernácula, lo que nos da la oportunidad de analizarla como un fenómeno cultural extendido desde México al Norte de California. Veremos aquí que las raíces del imaginario mexicano se hunden en la Conquista española y surgen en la actualidad dando como resultado una "nueva" estética arquitectónica.

    The whole-rock K-Ar dates from porphyry copper prospects of Paramillos Sur (phyllic and potasic alteration zones) and Paramillos Norte (propilitic zone) are reported. Radiometric data yielded 17,8 ± 0,9 Ma, 15,8 ± 1,0 Ma and 15,2 ± 0,5 Ma in Paramillos Sur, and 17,3 ± 0,7 Ma in Paramillos Norte, which can be added to an previously reported age of 16,4 ± 0,3 Ma. These data are in agreement with isotopic ages from non altered or non mineralized magmatic rocks of the region. When the isotopic ages and petrographic characteristics of the dated rocks are considered, two alteration-mineralization events are suggested for Paramillos Sur prospect. However this possibility needs to be confirmed by means of future studies, in view of the reduced interval between these events when compared with the analytical errors. (author)

Luego se hizo la identificación de la ruta de movimiento de zánganos, utilizando globos inflados con helio y barriletes. Cada punto de contacto de zánganos en el cebo, fue georeferenciado con GPS. Encontramos la primera ACZ en el norte de Argentina, cerca de una cabaña de crianza de reinas en Alberdi, Tucumán (ARG. Este estudio es importante ya que implementa una metodología para monitorear ACZ, la cual ayudaría en el estudio de la salud de las abejas y en la estimación de la estructura y diversidad genética de Apis mellifera L., también en apicultura, ya que brindaría una herramienta a los apicultores para la conservación de los ecotipos regionales mediante el planeamiento reproductivo de las abejas.

    Full Text Available En este trabajo se presentan los resultados del estudio realizado sobre restos de obsidiana, los cuales constituyen los primeros registrados en contextos arqueológicos de las selvas meridionales de la provincia de Tucumán. Estos materiales fueron recuperados en capas estratigráficas del primer milenio D.C. correspondientes al sitio Santa Rosa, el cual se ubica en la base de las laderas orientales de la Sierra del Aconquija (Tucumán, Argentina. Se realizó un análisis técnico-morfológico de los especímenes, en conjunto con un análisis geoquímico mediante fluorescencia de rayos X (FRX para determinar la procedencia geográfica de los materiales de obsidiana. Los resultados determinaron que la materia prima de la muestra, compuesta exclusivamente por desechos de talla, procede de la cantera de Ona-Las Cuevas, la cual se ubica a ca.270 km al noroeste del sitio Santa Rosa, en el norte de la provincia de Catamarca, en la Puna meridional argentina. La gran distancia sitio-cantera nos lleva a proponer que las comunidades prehispánicas de estas tierras bajas habrían participado de esferas estables de interacción con grupos de áreas muy distantes, propiciando la circulación e intercambio de obsidianas dentro de la porción meridional del NO de Argentina. Abstract In this paper we present the results of the study conducted on obsidian specimens, which constitutes the first record of this kind in archaeological contexts of the southern forests of the province of Tucumán are presented. These materials were recovered in stratigraphic layers of the first millennium AD of the Santa Rosa site, which is located at the base of the eastern slopes of the Sierra del Aconquija (Tucumán, Argentina. A techno-morphological analysis of specimens in conjunction with geochemic alanalysis using X-ray fluorescence (XRF was performed to determine the geographical provenance of obsidian archaeological materials.

    Full Text Available En este artículo se presenta un primer mapa social, geográfico y temporal de las encomiendas y pueblos de indios de Córdoba desde la fundación de la ciudad en 1573 hasta la expropiación de las tierras de las últimas comunidades indígenas reconocidas por el estado provincial entre 1880 y 1900. Esta reconstrucción, que tiene su punto de partida en preguntas, problemas y perspectivas de la etnohistoria, se sustenta en la confrontación y sistematización de información proveniente de un conjunto muy nutrido y variado de fuentes: visitas, padrones, expedientes, catastros e informes de autoridades. Dentro de un universo mayor de indios registrados por la administración colonial en el siglo XVII, se realiza el rastreo de veintiún casos hasta el final del período abordado. Para los once pueblos de más larga persistencia, se analizan con mayor detalle sus agregaciones, desmembramientos, traslados y cambios de nominación, relacionándose estos cambios y persistencias con la presencia o ausencia de los pueblos en el registro documental. Sobre la base de este rastreo y los aportes de estudios recientes, se proponen algunas claves que pueden contribuir a explicar los divergentes derroteros de estos pueblos.   Palabras clave: pueblos de indios; encomiendas; registro; historia; persistencia. Abstract This article presents a social, geographical, and temporal map of the encomiendas and Indian towns of Cordoba from the foundation of the city in 1573 to the expropriation of the lands belonging to the last indigenous communities that were recognized by the provincial state between 1880 and 1900. This reconstruction –whose starting point is a set of ethnohistorical questions, problems, and perspectives- is based on the comparison and systematization of information from a very rich and varied set of sources: visits, censuses, cadastres, lawsuits, and reports by authorities.

    Full Text Available This paper analyses the culture of milk and it includes both the micro social aspects of household consumption and the economic macro aspects related to milk production and their market and the welfare distribution in public policies against poverty. The hypothesis is that in Argentina there is a real culture of milk, which gives meaning to consumption, and marks the different income groups within society, as well as their gender and age. But since approximately 20 years ago, in accordance with the restructuring of the dairy industrial complex, that culture of milk has been changing, and its most outstanding features are the following: abandonment of milk as the emblematic food for children and its extension to the adult “formal” consumption; milk is no longer the knowledge of women and becomes the knowledge of experts; increase in milk consumption (dairy products in general as food gets feminine, infantile, medicated, globalised and segmented.Este artículo sobre la cultura de la leche analiza los aspectos microsociales del consumo en el hogar y los aspectos macro de la economía que hacen a la industria lactea y al mercado junto a la distribución asistencial del estado en los programas contra la pobreza. La hipótesis es que en Argentina existe una verdadera cultura de la leche, que da sentido al consumo, marcando con el alimento los diferentes sectores de ingreso de la sociedad, los géneros y las edades. Pero desde hace aproximadamente 20 años, en consonancia con la reconversión del complejo industrial lácteo, esta cultura de la leche esta cambiando, se describen sus aspectos mas salientes tales como : el abandono de la leche como alimento emblemático de los niños y su extensión al consumo “formal” adulto ; deja de ser un alimento rutinario cuyo saber usar residía en las mujeres y su uso pase a ser cosa de especialistas ; a medida se feminiza, infantiliza, medicaliza, globaliza y segmenta la alimentación en general

    A report and an updated list with comments on the species of freshwater molluscs of Argentina which covers an area of 2 777 815 km2 is presented. Distributions of Gastropoda and Bivalvia families, endemic, exotic, invasive as well as entities of sanitary importance are also studied and recommendations on their conservation are provided. Molluscs related to the Del Plata Basin have been thoroughly studied in comparison to others areas of the country. This fauna exhibits relatively the biggest specific richness and keeps its affinity with the fauna of other regions of the basin in areas of Paraguay and Brasil. The 4 500 records of molluscs considered in this paper arise from the study of the collections of Museo Argentino de Ciencias Naturales "Bernardino Rivadavia", Buenos Aires; Museo de La Plata, La Plata and Fundación "Miguel Lillo", Tucumán. These institutions keep very important collections of molluscs in southern South America. Field information has recently been obtained and localities cited by other authors are also included in the data base. Until today, 166 species have been described, 101 belonging to 10 families of Gastropoda and 65 to 7 of Bivalvia. Families with highest specific richness are Lithoglyphidae (22) and Sphaeriidae (25), respectively. The number of endemic species (those present only in Argentina) by family is: Gastropoda: Ampullariidae (1), Cochliopidae (10), Lithoglyphidae (11), Thiariidae (3), Chilinidae (11), Lymnaeidae (2) and Physidae (2?); Bivalvia: Hyriidae (1?); Etheriidae (1?) and Sphaeriidae (10). Families with a distribution that comprise almost the whole country are: the Sphaeriidae and the gastropods Cochliopidae, Chilinidae and Lymnaeidae. Families Erodonidae and Solecurtidae (Bivalvia) were registered in mixohaline environments from Buenos Aires province. Gastropod families Thiaridae and Glacidorbiidae show a very restricted distribution. The rest of the families are present mainly in the center and north of the country

    Full Text Available El presente estudio tiene como finalidad el desarrollar un modelo econométrico que permita evaluar y comparar los factores que influyen en la demanda de trabajo de la industria maquiladora de exportación (IME, de los estados de la frontera norte de México. Se construye una función de demanda de trabajo que considera como variables explicativas a: las remuneraciones, la actividad industrial en los Estados Unidos como "proxi" del ingreso y las economías de aglomeración derivadas de la especialización y concentración industrial. En el estudio se considera que los factores de localización regional relacionados con el mercado de trabajo son elementos determinantes de la demanda de trabajo y explicativos de los incrementos salariales de la IME en los estados de la frontera norte. Los resultados del trabajo muestran que el nivel salarial, el tamaño medio de las plantas maquiladoras y la especialización de la producción de la IME determinan a la demanda de trabajo de la IME, en estados de la frontera norte de México .
