    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 Santa Elena Ophiolite (SEO), located on the northwestern coast of Costa Rica, consists primarily of preserved oceanic mantle and crustal rocks thrust above an accretionary complex. The SEO is predominantly characterized by mantle peridotites (i.e., primarily spinel lherzolite with minor amounts of harzburgite and dunite) cut and intruded by minor pegmatitic gabbros, layered gabbros, plagiogranites, and doleritic and basaltic dykes. Previous studies have concluded that the complex formed in a suprasubduction zone (SSZ) setting based on the geochemical nature of the layered gabbros and plagiogranites (i.e., depleted LREE and HFSE and enriched LILE and Pb), as well, as the peridotites (i.e., low-TiO2, Zr, and V, and high MgO, Cr, and Ni)(Denyer and Gazel, 2009). Eighteen ultramafic samples collected during the winter 2010/2011 field season (SECR11) exhibit abundant evidence for melt-rock reaction (e.g., disseminated plagioclase and plagioclase-spinel, clinopyroxene-spinel, and plagioclase-clinopyroxene symplectites) and provide a unique opportunity to characterize the textural and chemical nature of melt-rock reaction in the SEO. We present the results of a petrologic investigation (i.e., petrography and electron probe microanalysis) of 28 thin sections (19 spinel lherzolites, of which 14 are plagioclase-bearing, 4 pyroxenite veins, and 5 harzburgites) derived from the SECR11 sample set. The results of this investigation have the potential to better our understanding of the nature of melt generation and migration and melt-rock interaction in the SEO mantle section and shed further light on the complex petrogenetic history of the SEO.

    The CERN Antiproton Decelerator (AD) provides antiproton beams with a kinetic energy of 5.3 MeV to an active user community. The experiments would profit from a lower beam energy, but this extraction energy is the lowest one possible under good conditions with the given circumference of the AD. The Extra Low Energy Antiproton ring (ELENA) is a small synchrotron with a circumference a factor of 6 smaller than the AD to further decelerate antiprotons from the AD from 5.3 MeV to 100 keV. Controlled deceleration in a synchrotron equipped with an electron cooler to reduce emittances in all three planes will allow the existing AD experiments to increase substantially their antiproton capture efficiencies and render new experiments possible. ELENA ring commissioning is taking place at present and first beams to a new experiment installed in a new experimental area are foreseen in 2017. The transfer lines from ELENA to existing experiments in the old experimental area will be installed during CERN Long Shutdown 2 (LS2) in 2019 and 2020. The status of the project and ring commissioning will be reported. This article is part of the Theo Murphy meeting issue `Antiproton physics in the ELENA era'.

    The renewable energy issue opens the door to an ambient of opportunities. Santa Elena, one of the coastal provinces of Ecuador has the chance to go from a fossil fuel energy culture to a new energy scheme based on the use of environmental friendly fuels like natural gas and other renewable energy carriers like hydrogen. The marginal production of oil and natural gas from the Gustavo Galindo Velasco field and the updated gas reserves from the Gulf of Guayaquil make it possible. Infrastructure for natural gas production and distribution for vehicles is almost ready and any of the three refineries can generate hydrogen from natural gas. This provides the opportunity to reshape the Santa Elena transport energy matrix, where vehicles can burn natural gas and inter country buses can work with hydrogen. Traditional Fishing boats can be fitted with hydrogen storage and fuel systems later on. Santa Elena should face this challenge through a joint effort of public and private parties. Santa Elena State University and its partners as a focus point to create: The Campus of Energy Knowledge, where research, science and technology will serve companies that work in the energy business with a strong synergy, which will create jobs for the Santa Elena people.

    CERN has a longstanding tradition of pursuing fundamental physics on extreme low and high energy scales. The present physics knowledge is successfully described by the Standard Model and the General Relativity. In the anti-matter regime many predictions of this established theory still remain experimentally unverified and one of the most fundamental open problems in physics concerns the question of asymmetry between particles: why is the observable and visible universe apparently composed almost entirely of matter and not of anti-matter? There is a huge interest in the very compelling scientiic case for anti-hydrogen and low energy anti-proton physics, here to name especially the Workshop on New Opportunities in the Physics Landscape at CERN which was convened in May 2009 by the CERN Directorate and culminated in the decision for the final approval of the construction of the Extra Low ENergy Antiproton (ELENA) ring by the Research Board in June 2011.

    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 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

    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.

    The CERN's Antiproton Decelerator (AD) is devoted to special experiments with low energy antiprotons. A main topic is the antihydrogen production with the present aim to produce these antimatter atoms with such low energy that they can be trapped in a magnetic gradient field. First very convincing results have been published recently by ALPHA. Still, it appears to be cumbersome, time consuming and ineffective when collecting the needed large numbers and high densities of antiproton clouds with the present AD. Both the effectiveness and the availability for additional experiments at this unique facility would drastically increase, if the antiproton beam of presently 5 MeV kinetic energy would be reduced by an additional decelerator to something like 100 keV. Such a facility 'ELENA', as an abbreviation for Extra Low ENergy Antiproton Ring and first discussed in 1982 for LEAR, was freshly proposed with a substantial new design and revised layout and is presently under consideration. ELENA will increase the number of useful antiprotons by up to two orders of magnitude and will allow to serve up to four experiments in parallel.

    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.

    This paper describes the new Antiproton Decelerator (AD) orbit measurement system and the Extra Low ENergy Antiproton ring (ELENA) orbit, trajectory and intensity measurement system. The AD machine at European Organization for Nuclear Research (CERN) is presently being used to decelerate antiprotons from 3.57 GeV/c to 100 MeV/c for matter vs anti-matter comparative studies. The ELENA machine, presently under commissioning, has been designed to provide an extra deceleration stage down to 13.7 MeV/c. The AD orbit system is based on 32 horizontal and 27 vertical electrostatic Beam Position Monitor (BPM) fitted with existing low noise front-end amplifiers while the ELENA system consists of 24 \\gls{BPM}s equipped with new low-noise head amplifiers. In both systems the front-end amplifiers generate a difference (delta) and a sum (sigma) signal which are sent to the digital acquisition system, placed tens of meters away from the AD or ELENA rings, where they are digitized and further processed. The beam position is calculated by dividing the difference signal by the sum signal either using directly the raw digitized data for measuring the turn-by-turn trajectory in the ELENA system or after down-mixing the signals to baseband for the orbit measurement in both machines. The digitized sigma signal will be used in the ELENA system to calculate the bunched beam intensity and the Schottky parameters with coasting beam after passing through different signal processing chain. The digital acquisition arrangement for both systems is based on the same hardware, also used in the ELENA Low Level Radio Frequency (LLRF) system, which follows the VME Switched Serial (VXS) enhancement of the Versa Module Eurocard 64x extension (VME64x) standard and includes VITA 57 standard Field Programmable Gate Array Mezzanine Card (FMC).

    In 2011 the ELENA decelerator was approved as a CERN project. Initially one extraction was foreseen, which should use a kicker and a magnetic septum which can be recuperated from an earlier installation. Since then a second extraction has been approved and a new solution was studied using only electric fields to extract the beam. This will be achieved by fast pulsing a separator, allowing single-bunch but also a full single-turn extraction from ELENA towards the experiments. The extraction and transfer requirements of ELENA are described, followed by the principal differences between the magnetic and electric field concepts. The design of electrostatic focussing and bending devices for the transfer lines will be presented. Finally the field quality which can be achieved with the separator and the concept of its power supply will be discussed.

    The future ELENA ring at CERN will decelerate the AD anti-proton beam further from 5.3 MeV to 100 keV kinetic energy, to increase the efficiency of anti-proton trapping. At present there are four experiments in the AD hall which will be complemented with the installation of ELENA by additional three experiments and an additional source for commissioning. This paper describes the optimization of the transfer line geometry, ring rotation and source position. The optics of the transfer lines and error studies to define field and alignment tolerances are shown, and the optics particularities of electrostatic elements and their optimization highlighted.

    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

    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)

It is said that by growing older he started to lose his capacity of taking decisions, so he was more and more dependent on her. The idea is credited by a serious number of historians. However, this is a false perspective.

    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)

    Full text: In this work measurements of the Radon ({sup 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 {sup 222}Rn in environments at different levels we inferred that the soil underlying the buildings does not represent an important source of {sup 222}Rn. The main occurrence of the element was found in room walls, which shows that local building materials are an important source of {sup 222}Rn. Among the materials used in these buildings are granitic rocks, and to a lesser extent, lime, sand and marble. The {sup 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 {sup 222}Rn allows us to conclude that its values decrease to accepted levels by means of a natural and efficient ventilation of the rooms.

Las concentraciones de radon 222 se determinaron con un detector pasivo Radon Monitor 05-418, marca Victoreen. El mismo consta de una camara de difusion electrostatica y un detector de estado solido (Si) de juntura difundida. No se observo, en los resultados obtenidos, influencias causadas por factores meteorologicos como la temperatura ambiente y la presion atmosferica. Por comparacion de la concentracion de radon 222 en ambientes ubicados en distintas plantas se dedujo que el suelo subyacente bajo los edificios representa una fuente secundaria

  17. Unlocking investment in cities: ELENA-EIB technical assistance facility

    Cicmanova, Jana; Garabetian, Thomas

    2015-06-01

    Energy Cities prepared a review of projects undertaken in the cities of Paris, Malmoe (in association with Lund and Helsingborg), Barcelona, Bristol and Brussels-Capital that received support from the ELENA-EIB facility. The aim of this study is to identify the ways in which technical assistance programs such as ELENA-EIB can help unlock investment in cities. The projects we reviewed (developed by Energy Cities' members) cover a wide array of sectors, from public building refurbishment to public transport or renewable energy production. These five projects illustrate how cities can focus on developing capacity in a long-term perspective, looking at the expected benefits of an investment or a support mechanism beyond that of the project itself. Overall, we found that project development assistance mechanisms such as ELENA can be beneficial to trigger investment for climate action in cities. Cities maximise the benefits of such a program by looking at how their climate-protection actions can generate benefits for the citizens, or how to systematically integrate climate action in other investment projects. Project development assistance (PDA) affects cities by allowing them to develop a new vision of the way they prepare an investment program. The search of synergies and the override of silo mentalities were a core element in the projects we reviewed. Indeed, the support provided by the European Union through ELENA-EIB is used by the local authorities to develop a transversal approach to climate action. The grant provided for PDA and the requirements of the ELENA-EIB facility represent an opportunity for local authorities to set up a new strategy regarding energy efficiency and renewable energy actions. It can be the necessary push for cities and local authorities to change the way they plan their investments, and develop projects to achieve their climate objectives. Besides, the grant is used for building long-term capacity in the development of investment programs

    Suarez, Rafael

    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.

    Schimmenti, Adriano

    2017-01-01

    In 1930, Italian psychiatrist Giovanni Enrico Morselli described the history, diagnosis, and treatment of his patient Elena. The case of Elena has been considered in literature as one of the most remarkable cases of multiple personality ever published. In fact, before treatment, Elena showed alternating French- and Italian-speaking personalities, with the Italian personality knowing nothing of her French counterparts. After a difficult treatment involving recovered memories of incestuous attacks by her father, which were proven to be true, Elena fully recovered from her symptoms. In this article, the author presents details of the case that were not available in the international literature before. He also discusses Elena's psychological and somatoform symptoms according to a contemporary perspective on the relationally traumatic origins of dissociation and dissociative identity disorder.

    This paper deals with some aspects of the mining prospection of clays in the South of Cordoba (Spain). That studied clays are used as raw materials in a processing plant of ceramic products. In this ground characterisation for future mining operations, low proportion of carbonated materials was searched. To carry out the study, three seek areas were defined, each one of them of about 4 Km{sup 2}, where two geophysical methods were applied (Electrical Resistivity Tomography and Vertical Electrical Sounding). X-ray diffraction, EDAX, direct cut, compaction, swelling and bearing capacity tests, among others, were carried out in samples picked up in each seek area. Using the information provided by all these tests the most interesting areas for the exploitation defined. These studies resulted in the selection of new interesting deposits for the clay industry.

    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

    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

    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.

    The Extra Low Energy Antiproton ring (ELENA) is a CERN project aiming at constructing a small 30 m circumference synchrotron to further decelerate antiprotons from the Antiproton Decelerator AD from 5.3 MeV to 100 keV. Controlled deceleration in a synchrotron equipped with an electron cooler to reduce emittances in all three planes will allow the existing AD experiments to increase substantially their antiproton capture efficiencies and render new experiments possible. The ELENA design is now well advanced and the project is moving to the implementation phase. Component design and construction are taking place at present for installation foreseen during the second half of 2015 and beginning of 2016 followed by ring commissioning until the end of 2016. New electrostatic transfer lines to the experiments will be installed and commissioned during the first half of 2017 followed by the first physics operation with ELENA. Basic limitations like Intra Beam Scattering limiting the emittances obtained under electron ...

    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.

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

    2004-01-01

    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

    The archaeocyathan collection of the Ermitas Hill (Cordoba) of the Geominero Museum in Madrid has recently been revised due to the discovery of some documents related to the study by one of this paper's authors of the professional life of Eduardo Hernandez-Pacheco in the National Natural History Museum archives. This documentation shows that the Ermitas Hill archaeocyathan collection now preserved in the Geominero Museum were sent by Eduardo Hernandez-Pacheco to Lucas Mallada before 1902 to be incorporated in the museum's collections and were then studied by Hernandez Sampelayo in 1933 and 1935. This fact implies that this collection is the oldest Spanish archaeocyathan collection deposited in a Spanish museum, besides clearing up the doubts about its origins and when the material was in deposited in the Geominero Museum.

    The CERN Extra Low ENergy Antiproton (ELENA) Ring is a new synchrotron that will be commissioned in 2016 to further decelerate the antiprotons coming from CERN’s Antiproton Decelerator (AD). Required longitudinal diagnostics include the intensity measurement for bunched and debunched beam and the measurement of Dp/p to assess the electron cooling performance. A novel method for the calculation of these parameters is proposed for ELENA, where signals from the twenty electrostatic Pick-Ups (PU) used for orbit measurements will be combined to improve the signal-to-noise ratio. This requires that the signals be digitally down-converted, rotated and summed so that the many electrostatic PUs will function as a single, distributed PU from the processing system viewpoint. This method includes some challenges and will not be used as the baseline longitudinal diagnostics for the initial ELENA operation. This paper gives an overview of the hardware and digital signal processing involved, as well as of the challenges t...

    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)

  3. Intraspecific variation in erythrocyte sizes among populations of Hypsiboas cordobas (Anura: Hylidae

    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.

    The archaeocyathan collection of the Ermitas Hill (Cordoba) of the Geominero Museum in Madrid has recently been revised due to the discovery of some documents related to the study by one of this paper's authors of the professional life of Eduardo Hernandez-Pacheco in the National Natural History Museum archives. This documentation shows that the Ermitas Hill archaeocyathan collection now preserved in the Geominero Museum were sent by Eduardo Hernandez-Pacheco to Lucas Mallada before 1902 to be incorporated in the museum's collections and were then studied by Hernandez Sampelayo in 1933 and 1935. This fact implies that this collection is the oldest Spanish archaeocyathan collection deposited in a Spanish museum, besides clearing up the doubts about its origins and when the material was in deposited in the Geominero Museum.

    1989-01-01

    A Mining Feasibility Study in the Area of Alto San Jorge, Department of Cordoba, Colombia, was commissioned by CARBOCOL S.A. to the Consortium Geominas-NACI. An area of 800 Ka2 was explored to define surface mining possibilities within two subareas referred to as Alto San Jorge and San Pedro Ure. Rocks of Cretaceous, Tertiary and Quaternary age crop out in the zone. In the subarea Alto San Jorge the principal structure is a syncline with a south-north direction. The San Pedro Ure subarea is formed by undulations with flanks of low dip, the most important being the San Antonio Syncline because it contains the mining block. The geological study of the surface demonstrated the existence of coal in the Oligocene Cienaga de Oro Formation and the Niocene Cerrito Formation, with potential resources of 6.3 billion tons. The subsequent exploration of the subsoil, with 20.618 m of drilling, permitted determination of demonstrated reserves in the order of 2.9 billion tons within two areas. In the sector selected for the mine plan, in the area of San Pedro-Puerto Libertador, 7.791 m of drilling was accomplished to define a demonstrated reserve of 515 million tons of coal down to a depth of 200. The combustible type coal has 5.000 cal/g. Complete mining schedules were developed at the prefeasibility level for two surface mines with productions of 1.5 MMTY and 4 MMTY. 9 figs., 3 tabs., 28 refs.

    Full Text Available One of the most singular characteristics of peronism is the originality of holding within it a double charismatic leadership complementary to each other. The quintessential paradigm corresponds to Perón and Eva Perón, but there were other cases, more modest, that have served to cement the argentine political culture: the marriage at power. Those first ladies redefined its role, and built spaces of power and influence in government. In this paper I analyze the role of Elena Caporale de Mercante and her new political role as wife of the most important governor who had the first Peronist government.

    2009-02-15

    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)

    The application of diagnostic techniques in nuclear medicine is ever growing as part of clinical daily routine. Although the diagnostic procedures carry a negligible clinical risk, the introduction of radioactive substances into the patient makes it imperative to determine the effective dose to minimize the stochastic effects to the patient thus establishing the collective dose to the community. The aim of our work is to study the collective effective dose imparted by Nuclear Medicine Service during 1997 to Cordoba and Jaen inhabitants (1 448 988). The nuclear medicine techniques of bone exploration with 11 454 mSv-person (4,6 mSv/exploration) and thyroid scintigraphy with 6181 mSv-person (7,0 mSv /exploration) are the main techniques implicated in the relative contribution to the total annual effective collective dose of 35 901.2 mSv-person

    2012-01-01

    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.

    Agua de Ramon district is located in the NW of Cordoba, Argentina, between 3 49' and 30{sup 0}52' S and 65{sup 0}21' and 65{sup 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.

    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{sup 3}) at the night and a minimum value (150 Bq/m{sup 3}) at the day. (author)S.

    Full Text Available Las comunas de la Península de Santa Elena representan la continuidad histórica de las antiguas jefaturas Manteño - Huancavilcas. Estas comunas han logrado mantener el control de su territorio y una relativa autonomía socio-económica a lo largo de todo el período colonial y republicano, poniendo en práctica diversas estrategias de articulación con la sociedad dominante. Sin embargo, la supervivencia de estas comunidades se debate, hoy en día, entre las agresiones extemas a su temitodo, y su "etnicidad marginal" que las excluye del marco constitucional ecuatoriano destinado a la protección de los tenitorios étnicos. A continuación se analiza el proceso de resignificación de la diversidad al que están abocadas las comunas de la PSE.

    The efficient production of cold antihydrogen atoms in particle traps at CERN's Antiproton Decelerator has opened up the possibility of performing direct measurements of the Earth's gravitational acceleration on purely antimatter bodies. The goal of the AEgIS collaboration is to measure the value of g for antimatter using a pulsed source of cold antihydrogen and a Moiré deflectometer/Talbot-Lau interferometer. The same antihydrogen beam is also very well suited to measuring precisely the ground-state hyperfine splitting of the anti-atom. The antihydrogen formation mechanism chosen by AEgIS is resonant charge exchange between cold antiprotons and Rydberg positronium. A series of technical developments regarding positrons and positronium (Ps formation in a dedicated room-temperature target, spectroscopy of the n=1-3 and n=3-15 transitions in Ps, Ps formation in a target at 10 K inside the 1 T magnetic field of the experiment) as well as antiprotons (high-efficiency trapping of ?, radial compression to sub-millimetre radii of mixed ? plasmas in 1 T field, high-efficiency transfer of ? to the antihydrogen production trap using an in-flight launch and recapture procedure) were successfully implemented. Two further critical steps that are germane mainly to charge exchange formation of antihydrogen-cooling of antiprotons and formation of a beam of antihydrogen-are being addressed in parallel. The coming of ELENA will allow, in the very near future, the number of trappable antiprotons to be increased by more than a factor of 50. For the antihydrogen production scheme chosen by AEgIS, this will be reflected in a corresponding increase of produced antihydrogen atoms, leading to a significant reduction of measurement times and providing a path towards high-precision measurements. This article is part of the Theo Murphy meeting issue `Antiproton physics in the ELENA era'.

    Argentina is among the Ibero-American countries with the greatest old age population, and is going through a process of advanced demographic transition. Elderly adults have long been considered a vulnerable group in need of care. The purpose of this work was to problematize the conceptions underlying the care given to the elderly in nursing homes, and the possible slides this involves from a human rights stance. An approach to this problem was built up by resorting to secondary documentary sources and interviews with key informants located in institutions for the elderly in the Province of Cordoba. This approach revealed a predominantly asylum-oriented conception centered on caring for others as objects, and a noticeable lack of consideration for the elderly as legal subjects, visible in numerous serious infringements of human rights, mostly silenced and rendered invisible. It seems that to overcome these situations it will be necessary not merely to review legal loopholes and current programs but also to reconsider the place given to the elderly in society. Regardless of their age and other social differences, the elderly require the same opportunities to claim full respect and exercise their human rights and fundamental freedoms.

    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 Summary: 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.

    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

    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.

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

    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

    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)

    Full Text Available The massacre of Tlatelolco in 1968 was the most bloody incident of Diaz Ordaz’s government in Mexico and promoted a severe process of persecution and repression of the student movement. One of its consequences was the suspicion of betrayal by Elena Garro of the movement’s intellectual authors. Since then, Garro embodied an abject character of collaboration, in constant harassment, leading to her exile during twenty years.This paper considers the implications of the accusation and the diagnosis of insanity that accompanies it. For some critics this insanity is redeemed in her literary work, which in this operation achieves prominence; but the insanity can be thought of as irreducible. Garro’s delirious gaze doesn’t sublimate the trauma, but repeats again and again the political violence, with harassed, exposed and out of place characters, in situations of daily totalitarianism. Figures of betrayal emerge in her histories, involving characters and knowledge outside the language of the official left (animal, children, women, the indigenous, marked by their helplessness and questioning the premises of political parties.

    Full Text Available In the nineteenth and the first half of the twentieth century, Italy held a strong appeal for Russian travelers. Several of these Russian émigrés were women of Jewish lineage, who had come with their families or were sent abroad on their own in order to complete their education at one of the newborn kingdom’s prestigious universities. Elena Raffalovich (Odessa 1842 – Florence 1918 is one of the earliest and most intriguing examples of this phenomenon. While her intellectual trajectory, as a pioneer in children’s education and an advocate of women’s rights, is representative of that of many other Russian Jewish women living in Italy at that time, it also challenges a number of historiographic commonplaces about Jewish women and their emancipation process in nineteenth-century Europe. Moreover, through the archives of different prominent members of the Raffalovich dynasty, it is possible to follow its vicissitudes over at least five generations, completing our knowledge of Elena’s biography and reassessing the importance of her intellectual contribution to Italian culture.

    The evaluation of metal contents in the environment is of vital importance for the assessment of human exposure. Thus the species Usnea amblyoclada, Ramalina celastri and Tillandsia capillaris were tested as bioaccumulators of transition metals in the urban area of Cordoba city, Argentina. The level of metals on biomonitors was compared to that of total deposition samples. All three species discriminated zones within the urban area of Cordoba city with different pollution levels; they revealed high levels of Zn in the downtown area and confirmed high levels of some transition metals in an industrial area. The correlation analysis revealed that the lichen R. celastri had the highest correlation rates with total deposition samples, suggesting it is a valuable biomonitor of atmospheric pollution. A significant relationship was also observed between respiratory diseases in children and the contents of metal accumulated in R. celastri and T. capillaris, indicating their usefulness when assessing human exposure to metals. - Metal accumulation in epiphytes is correlated with human respiratory diseases.

    The aim of this work was to analyze the composition of river waters and to study their quality by detecting possible contaminants. The samples were taken at 32 points of the Suquia River in its stream across the city of Cordoba (in the Province of Cordoba, Argentina). The samples were analyzed with total reflection X-ray fluorescence (TXRF) using beam guides. Beam guides made of two Si plate reflectors were used as sample carriers and to guide the X-ray photons to the sample; the measurements were taken using the characteristic configuration that ensures the best excitation and detection conditions (in TXRF). The analyses were carried out by preconcentration of the water samples and by adding an internal standard (Gallium); small amounts of samples (30 μl) were deposited on the Si reflector plate and they were then analyzed in the total reflection regime. Spectra were analyzed with standard methods using conventional programs. The results show interesting behaviors of the concentration of trace elements along the river: elements of low atomic number (such as Ca, Cl, S, K) present higher concentrations as compared to high Z elements (such as Fe, Zn, Br, Sr); the concentrations of light elements follow a similar behavior along the stream, the same situation is observed in the set of elements with high atomic number. Some samples present high concentrations in certain elements indicating possible sources of contamination

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.

    The accreditation process is, on the one hand, a tool used to homogenize procedures, rendering comparable and standardized processes of care, and on the other, a methodology employed to develop a culture of quality improvement. Although not yet proven by evidence-based studies that health outcomes improve as a result of an accreditation to excellence, it is undeniable that better control of healthcare processes results in better quality and safety of diagnostic and therapeutic pathways. The Regina Elena National Cancer Institute underwent the accreditation process in accordance with the standards criteria set by the Organisation of European Cancer Institutes (OECI), and it has recently completed the process, acquiring its designation as a Comprehensive Cancer Center (CCC). This was an invaluable opportunity for the Regina Elena Institute to create a more cohesive environment, to widely establish a culture of quality, to implement an institutional information system, and to accelerate the process of patient involvement in strategic decisions. The steps of the process allowed us to evaluate the performance and the organization of the institute and put amendments in place designed to be adopted through 26 improvement actions. These actions regarded several aspects of the institute, including quality culture, information communication technology system, care, clinical trials unit, disease management team, nursing, and patient empowerment and involvement. Each area has a timeline. We chose to present the following 3 improvement actions: clinical trial center, computerized ambulatory medical record, and centrality of patient and humanization of clinical pathway.

    Full Text Available La palabra griega paránoia se compone de pará (fuera de y de noys (mente. Traducida literalmente significa “fuera de la mente”, expresión que remite a su vez a la palabra “locura”. De hecho, esa holgada acepción es la primera que registra El pequeño Larousse en su edición de 2003. Sin embargo, la psiquiatría ha restringido su significado. Los psiquiatras Alfred M. Freedman, Harold I. Kaplan y Benjamin J. Sadock, en su Compendio de Psiquiatría, la definen como un trastorno psicótico crónico que se caracteriza por una alta frecuencia de ideas delirantes, y distinguen cuatro estados paranoides: el celotípico, el erótico, el de grandeza y el persecutorio. Pero advierten que de estos cuatro estados, “el estado persecutorio es clínicamente, con mucho, el más frecuente y el más importante”. Si damos por descontado que la literatura es en buena medida reflejo de la realidad, tanto exterior como interior, no es de extrañar que de esos cuatro estados paranoides acaso el más frecuente en dicho arte, y el más importante también, lo sea el estado persecutorio paranoide. Pensando en la literatura hispanoamericana contemporánea, por lo menos dos escritores de la misma generación produjeron ficciones de corte autobiográfico con fuertes tintes de ese estadoparanoide: el argentino Ernesto Sábato en Abbadón el extermina- dor, novela publicada en 1974, y la mexicana Elena Garro en los cuen- tos y novelas que escribió algún tiempo después de 1968, sobre todo, y empezando por el título mismo, en el libro de cuentos que nos ocupará en el presente artículo, Andamos huyendo Lola, publicado en 1980.

    Full Text Available Uplifted ultramafic rocks represent an important vector for the transfer of carbon and reducing power from the deep subsurface into the biosphere and potentially support microbial life through serpentinization. This process has a strong influence upon the production of hydrogen and methane, which can be subsequently consumed by microbial communities. The Santa Elena Ophiolite (SEO on the northwestern Pacific coast of Costa Rica comprises ~250 km2 of ultramafic rocks and mafic associations. The climatic conditions, consisting of strongly contrasting wet and dry seasons, make the SEO a unique hydrogeological setting, where water-rock reactions are enhanced by large storm events (up to 200 mm in a single storm. Previous work on hyperalkaline spring fluids collected within the SEO has identified the presence of microorganisms potentially involved in hydrogen, methane, and methanol oxidation (such as Hydrogenophaga, Methylobacterium, and Methylibium spp., respectively, as well as the presence of methanogenic Archaea (such as Methanobacterium. Similar organisms have also been documented at other serpentinizing sites, however their functions have not been confirmed. SEO's hyperalkaline springs have elevated methane concentrations, ranging from 145 to 900 μM, in comparison to the background concentrations (<0.3 μM. The presence and potential activity of microorganisms involved in methane cycling in serpentinization-influenced fluids from different sites within the SEO were investigated using molecular, geochemical, and modeling approaches. These results were combined to elucidate the bioenergetically favorable methane production and/or oxidation reactions in this tropical serpentinizing environment. The hyperalkaline springs at SEO contain a greater proportion of Archaea and methanogens than has been detected in any terrestrial serpentinizing system. Archaea involved in methanogenesis and anaerobic methane oxidation accounted from 40 to 90% of total

    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.

    The authors of U.P.M. have had relations with Argentine Universities and Administrations, in part with J.M.Cisneros that is Professor at Universidad Nacional de Rio Cuarto in Prov. de Córdoba Arg., and have applied Decision Theories with Mathematic tools for the planning of defences and uses of soils in these areas and especially of La Colacha bassin enlarged with larger areas around it as "Cuenca de los Arroyos Menores" at West and South of Rio Cuarto. These large flat lands have loess soils brought by winds from Los Andes that are much far at West, there is a very old line of not high mountains at West near the study area from which rivers flow with little slopes to somehow lower flat areas at West with some marshes. Rivers through loess get regressive erosions with rains forming kilometres long ditches in the loess called "cárcavas" some meters deep and quite large across otherwise flat agricultural lands, and J.M. Cisneros, that has numerous publications about local soil uses, has directed diverse genie rural works to halt the regression of some of them. Part of the study is about protection against floods and "cárcavas". There are famous experiences and records of higher inundations of large areas by rivers. Latitude of Rio Cuarto is 31°25' South, that area is temperate refreshed by south winds, Zonda föhn winds from West being hotter and drier, and there are monsoons and so winter in July is dry and summer and December has rains, that average 829mm per year. Wind erosion and fires occur frequently on these loess soils in winter. This is an excellent area for agriculture but some actual uses may be not sustainable in long term such as excesses with genetically engineered soy, and the authors have studied aided with mathematical models (ELECTRE I, PROMETHEE and Expert Choice) the preferences of various alternative systems of land use (Autochthonous forest, High value forest, Traditional farms, Erosion control Crop with agriculture use, and Erosion control Crop with industrial use (biomass) ) in view of diverse Criteria (Water erosion index, Eolian erosion index, Implementation facility, Water resources, Economical Benefits, Hand power, Environmental Impacts, social Acceptance), as contribution for territorial planning, in part in relation with local official agencies.

    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

This work is a counter-discourse to Mexico's official narrative and the idealization of facts and national heroes. She is interested in the racist and classist aspects of the new dominating society, which is interested in their own personal welfare over those of the collective. To do so, she makes her characters concerned about buying a head, that is, an ideology to fundament their own existence.

    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.

    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.

    A geochemical study of the groundwater of the pampa in the province of Cordoba, Argentina, is reported. Physical-chemical parameters, dissolved solids, and seven trace elements were determined in 60 selected water samples. Systematic and accurate measurements of arsenic, fluorine, and vanadium were performed for the first time. The geographic distribution of the seven trace elements was mapped and its correlation with the anion-cation composition of the water was studied. Eighty-four percent of the water analyzed showed arsenic contents over 0.05 mg/l. The maxima for arsenic, fluorine, vanadium, and uranium contents were found in the western part of the study area, in waters dominated by alkali metal cations. Maximum selenium and antimony contents were found in the eastern part of the areas, whereas molybdenum distribution showed no relationship to the other groups. The movements of the subsoil have disturbed surface and subsurface drainage, thus influencing the water salinity and trace element contents. To investigate the origin of contamination, 54 loess samples were collected at wells in depths ranging from the surface down to the water table. This loess, which has a high proportion of volcanic components, mainly rhyolitic glass, exhibits a chemical composition corresponding to that of a dacite. The loess and volcanic glass show anomalous contents of all contaminant trace elements, mainly arsenic and selenium. For this reason, loess is considered to be the most important source of contamination of this ground water area. 30 refs., 6 figs., 9 tab

    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

    The Covenant of Mayors (CoM) is an initiative of the European Commission started in 2008 with the aim of involving cities more in the implementation of the 20-20-20 climate-energy package. To this end, a variety of tools to assist the realization of such a policy has been built. The European Local Energy Assistance (ELENA) program of the European Investment Bank (EIB) is one of the most relevant. In this work, we observe some data on the Italian participation in the CoM and ELENA program, while highlighting the role the Energy Service Companies have in these contexts. By referring to the specific experience of the Province of Foggia (an intermediary government body in southern Italy), we also discuss how some recent changes in the Italian legislation, aimed at abolishing the provinces (considered as preferred supporting structure of the CoM), imposed the identification of another supraterritorial entity. This is to substitute the Province of Foggia as coordinator in the dialog between the local territory and the European Union institutions on the climate-energy theme. In this sense, the choice of the Chamber of Commerce represents a novelty. With regard to this, some considerations on the appropriateness of this choice are developed. - Highlights: •The CoM is an EU environmental-energy initiative for local authorities. •The ELENA program supports technical energy efficiency activities within the CoM. •Chambers of Commerce can usefully coordinate ELENA projects submission. •Public bodies are committed to implement energy saving projects on their buildings. •The ESCOs develop and implement energy efficiency projects.

    The Terminal Cretaceous Chicxulub Impact Crater had a strong control on the depositional and diagenetic history of the northern Yucatan Platform during most of the Cenozoic Era. The Chicxulub Sedimentary Basin (henceforth Basin), which approximately coincides with the impact crater, is circumscribed by a concentration of karstic sinkholes known as the Ring of Cenotes. Santa Elena Depression (henceforth Depression) is the name proposed for the bowl-shaped buried feature, first contoured by geophysical studies, immediately south of the Basin, in the area where the Ticul 1 and UNAM 5 wells were drilled. Lithologic, petrographic, and biostratigraphic data on PEMEX, UNAM, and ICDP cores show that: 1) Cenozoic deposits are much thicker inside the Basin than inside the Depression, 2) in general, the Cenozoic formations from inside the Depression are the thickest among those outside the Basin, 3) variably dolomitized pelagic or outer-platform wackestone or mudstone occur both inside the Basin and Depression, 4) the age of the deeper-water sedimentary carbonate rocks is Paleocene-Eocene inside the Basin and Paleocene?-Early Eocene inside the Depression, 5) the oldest formations that crop out are of Middle Eocene age at the edge of the Basin and Early-Middle Eocene age inside the Depression, 6) saline lake deposits, that consist chiefly of anhydrite, gypsum, and fine carbonate, and also contain quartz, chert, clay, zeolite, potassium feldspar, pyrite, and fragments of wood, are present in the Cenozoic section of the UNAM 5 core between 282 and 198 m below the present land surface, 7) the dolomite, subaerial exposure features (subaerial crusts, vugs, karst, dedolomite), and vug-filling cement from the Eocene formations are more abundant inside the Depression than inside the Basin. The depositional environments that are proposed for explaining the Cenozoic facies succession within the Santa Elena Depression are: 1) deeper marine water (Paleocene?-Early Eocene), 2) relatively

    In humans, ingested inorganic arsenic is metabolized to monomethylarsenic (MMA) then to dimethylarsenic (DMA), although in most people this process is not complete. Previous studies have identified associations between the proportion of urinary MMA (%MMA) and increased risks of several arsenic-related diseases, although none of these reported on lung cancer. In this study, urinary arsenic metabolites were assessed in 45 lung cancer cases and 75 controls from arsenic-exposed areas in Cordoba, Argentina. Folate has also been linked to arsenic-disease susceptibility, thus an exploratory assessment of associations between single nucleotide polymorphisms in folate metabolizing genes, arsenic methylation, and lung cancer was also conducted. In analyses limited to subjects with metabolite concentrations above detection limits, the mean %MMA was higher in cases than in controls (17.5% versus 14.3%, p = 0.01). The lung cancer odds ratio for subjects with %MMA in the upper tertile compared to those in the lowest tertile was 3.09 (95% CI, 1.08-8.81). Although the study size was too small for a definitive conclusion, there was an indication that lung cancer risks might be highest in those with a high %MMA who also carried cystathionine β-synthase (CBS) rs234709 and rs4920037 variant alleles. This study is the first to report an association between individual differences in arsenic metabolism and lung cancer, a leading cause of arsenic-related mortality. These results add to the increasing body of evidence that variation in arsenic metabolism plays an important role in arsenic-disease susceptibility.

    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.

    In this second paper of The role of Environment in shaping Low-mass Early-type Nearby galaxies (hELENa) series we study [Mg/Fe] abundance distribution trends of early-type galaxies (ETGs) observed with the Spectrographic Areal Unit for Research on Optical Nebulae integral field unit, spanning a wide range in mass and local environment densities: 20 low-mass early types (dEs) of Sybilska et al. and 258 massive early types (ETGs) of the ATLAS3D project, all homogeneously reduced and analysed. We show that the [Mg/Fe] ratios scale with velocity dispersion (σ) at fixed [Fe/H] and that they evolve with [Fe/H] along similar paths for all early types, grouped in bins of increasing local and global σ, as well as the second velocity moment Vrms, indicating a common inside-out formation pattern. We then place our dEs on the [Mg/Fe] versus [Fe/H] diagram of Local Group galaxies and show that dEs occupy the same region and show a similar trend line slope in the diagram as the high-metallicity stars of the Milky Way and the Large Magellanic Cloud. This finding extends the similar trend found for dwarf spheroidal versus dwarf irregular galaxies and supports the notion that dEs have evolved from late-type galaxies that have lost their gas at a point of their evolution, which likely coincided with them entering denser environments.

    The CERN Extra Low ENergy Antiproton (ELENA) Ring is a new synchrotron that will be commissioned in 2016 to further decelerate the antiprotons transferred from the CERN’s Antiproton Decelerator (AD). The requirements for the acquisition and treatment of signals for longitudinal diagnostics are very demanding, owing to the revolution frequency swing as well as to the digital signal processing required. The requirements for the Low-Level Radio-Frequency (LLRF) system are very demanding as well, especially in terms of revolution frequency swing, dynamic range and low noise required by the cavity voltage control and digital signal processing to be performed. Both sets of requirements will be satisfied by using a leading-edge hardware family, developed to cover the LLRF needs of all synchrotrons in the Meyrin site; it will be first deployed in 2014 in the CERN’s PSB and in the medical machine MedAustron. This paper gives an overview of the main building blocks of the hardware family and of th...

El material, tanto fresco como usado, se caracterizó mediante DRX, área superficial BET y SEM-EPMA. El catalizador mostró una matriz de MgO tipo periclasa con CaO en la superficie. Las pruebas de actividad catalítica se efectuaron en lecho fijo empacado con partículas obtenidas mediante prensado, trituración y clasificación del material. El flujo de reactivos consistió en mezclas gas natural-aire por debajo del límite inferior de inflamabilidad. Para diferentes flujos y temperaturas de entrada de la mezcla reactiva, se midieron las concentraciones de CH4, CO2 y CO en los gases de combustión con un analizador de gases tipo infrarrojo no dispersivo (NDIR. Para alcanzar conversión total de metano se requirió aumentar la temperatura de entrada al lecho a medida que se incrementó el flujo de gases reaccionantes. Los resultados obtenidos permiten desarrollar un sistema de combustión catalítica de bajo costo con un material térmicamente estable, que promueva la alta eficiencia en la combustión de gas natural y elimine los problemas de estabilidad, seguridad y de impacto ambiental negativo inherentes a los procesos de combustión térmica convencional.

    Background: Salmorejo is gaining national reputation and international recognition. However, there are many different forms to prepare it and, therefore, the organoleptic and nutritional properties of the plateful may differ. Material and methods: In order to make standardization of salmorejoand its ways of production, which allow the protection of its identity and, furthermore, its nutritional characterization, around the 83% of catering establishments were surveyed in Cordoba (excluding suburbs and industrial area), to investigate how they produce this dish, as to name, ingredients, preparation, price, etc. They were personally given a survey with 55 questions divided into 6 sections. Results: The result is that only 21% of establishments used the name “salmorejo cordobés”, the ingredients used, consistently statistically adjusted to a previous proposal of systematization and nutritional assessment, based on literature data and broadcast in over 50 languages which corresponds to 1.000 g tomato, 200 g telerabread, 100 g of extra virgin olive oil, 5 g Montalbangarlic and 10g of salt. Then, 100g of this product corresponds to 117.4 kcal, 1.8 g protein, 8.1 g fat, 9.9 g carbohydrate, 1.2 g fiber and 380.7 mg of sodium. A minority of the establishments used vinegar like an extra ingredient (18% of surveys) and the majority used little pieces of ham and boiled egg as garnish. While more than 25% add a trickle of oil on the finished product. It is made mainly through glass mixer or food processor, being the majority recipe used form of family origin. Although salmorejowas traditionally considered a food for summer, 78% of establishments have it all year round. 94% of establishments consider it among the ten most ordered dishes, and in 18% it is the most ordered dish of the establishment. There is no relationship between the amount of salmorejo served with the price of the plateful, the latter being in line with other prices of the rest of establishment. Conclusions

  12. Determination of heavy metals and other elements by Neutron Activation Analysis in sediment cores of laguna Mar Chiquita (Cordoba, Argentina)

    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.

    We present the first in a series of papers in The role of Environment in shaping Low-mass Early-type Nearby galaxies (hELENa) project. In this paper, we combine our sample of 20 low-mass early types (dEs) with 258 massive early types (ETGs) from the ATLAS3D survey - all observed with the SAURON integral field unit - to investigate early-type galaxies' stellar population scaling relations and the dependence of the population properties on local environment, extended to the low-σ regime of dEs. The ages in our sample show more scatter at lower σ values, indicative of less massive galaxies being affected by the environment to a higher degree. The shape of the age-σ relations for cluster versus non-cluster galaxies suggests that cluster environment speeds up the placing of galaxies on the red sequence. While the scaling relations are tighter for cluster than for the field/group objects, we find no evidence for a difference in average population characteristics of the two samples. We investigate the properties of our sample in the Virgo cluster as a function of number density (rather than simple clustrocentric distance) and find that dE ages correlate with the local density such that galaxies in regions of lower density are younger, likely because they are later arrivals to the cluster or have experienced less pre-processing in groups, and consequently used up their gas reservoir more recently. Overall, dE properties correlate more strongly with density than those of massive ETGs, which was expected as less massive galaxies are more susceptible to external influences.

    Full Text Available En los Andes colombianos, un gran número de artesanías se fabrican a partir de raíces adventicias de plantas nativas que crecen de forma silvestre. Sin embargo, la deforestación y las prácticas no sustentables han diezmado la disponibilidad de plantas silvestres productoras de fibra. En este estudio evaluamos la disponibilidad de fibras de tres especies en Santa Elena (Antioquia, Colombia: Asplundia sarmentosa, Philodendron aff. sagittifolium y Clusia multiflora. Después de una búsqueda exhaustiva en la zona de estudio ubicamos menos de 30 individuos adultos de cada especie. Para cada planta se midieron las variables asociadas al tamaño de la planta y se registró el número y la longitud de raíces maduras e inmaduras. Se pesaron fragmentos de raíces para estimar la biomasa. El crecimiento de raíces de cada planta fue monitoreado mensualmente durante siete meses. La disponibilidad actual de fibra (raíces maduras es de ca. 3 352 m (Asplundia 1 481 m, Clusia de 952 m, Philodendron 918 m, con esta cantidad de material se pueden elaborar entre 419 a 838 canastos. De acuerdo a la tasa de crecimiento mensual, una nueva raíz podría alcanzar un tamaño para ser cosechado entre el mes 38 y 71. Plantas más grandes tienen mayor cantidad de raíces maduras, sin embargo, la tasa de crecimiento no está asociada al tamaño de la planta. Nuestros resultados proveen evidencia de que las plantas en Santa Elena presentan una relación (tamaño de la planta, número de raíces maduras que es similar a plantas que se encuentran en zonas no intervenidas, no obstante, la cosecha de fibras en Santa Elena no es una actividad sostenible debido al bajo número de individuos susceptibles de ser cosechados, la lenta tasa de crecimiento de raíces y la alta demanda de fibras. Es necesario implementar estrategias como el enriquecimiento del bosque con estas tres especies para garantizar una actividad sustentable para recolectores y artesanos en Santa Elena y

    Tourism in the province of Santa Elena has become a sector of great importance, which has been not only supported by government policies, but also by initiatives of businessmen and communities. Tourism planning has become the best tool for successful and sustainable development of the activity aiming towards the objectives set in the National Plan for Good Living, by following the guidelines established by PLANDETUR (Strategic Development Plan for Sustainable Tourism in Ecuador 2020, while accepting at the same time, the recommendations based on reality where tourism arises. One of the tangible needs is based on the lack of reliable information available about the characteristics of the demand in respect to the Sun and Beach tourism offer; which is the leading product of the province.  This data is significant to support decision-making for each of the actors that make up this vast sector.  This paper shows some results obtained in the investigation through the application of actions taken to design a tourist observatory targeted to the Sun and Beach tourism in Santa Elena, and monitored through the establishment of a base for the guidelines of a management system for tourism information, and by the establishment of the profile of domestic demand.

  4. Sulfur and carbon geochemistry of the Santa Elena peridotites: Comparing oceanic and continental processes during peridotite alteration

    2016-05-01

    Ultramafic rocks exposed on the continent serve as a window into oceanic and continental processes of water-peridotite interaction, so called serpentinization. In both environments there are active carbon and sulfur cycles that contain abiogenic and biogenic processes, which are eventually imprinted in the geochemical signatures of the basement rocks and the calcite and magnesite deposits associated with fluids that issue from these systems. Here, we present the carbon and sulfur geochemistry of ultramafic rocks and carbonate deposits from the Santa Elena ophiolite in Costa Rica. The aim of this study is to leverage the geochemistry of the ultramafic sequence and associated deposits to distinguish between processes that were dominant during ocean floor alteration and those dominant during low-temperature, continental water-peridotite interaction. The peridotites are variably serpentinized with total sulfur concentrations up to 877 ppm that is typically dominated by sulfide over sulfate. With the exception of one sample the ultramafic rocks are characterized by positive δ34Ssulfide (up to + 23.1‰) and δ34Ssulfate values (up to + 35.0‰). Carbon contents in the peridotites are low and are isotopically distinct from typical oceanic serpentinites. In particular, δ13C of the inorganic carbon suggests that the carbon is not derived from seawater, but rather the product of the interaction of meteoric water with the ultramafic rocks. In contrast, the sulfur isotope data from sulfide minerals in the peridotites preserve evidence for interaction with a hydrothermal fluid. Specifically, they indicate closed system abiogenic sulfate reduction suggesting that oceanic serpentinization occurred with limited input of seawater. Overall, the geochemical signatures preserve evidence for both oceanic and continental water-rock interaction with the majority of carbon (and possibly sulfate) being incorporated during continental water-rock interaction. Furthermore, there is

    This article focuses on the conceptions, attitudes and practices of the inhabitants from four villages (veredas) in Tierralta and Valencia (Cordoba, Colombia), who have suffered from or are aware of the existence of cutaneous leishmaniasis. A mixed methodology was implemented based in a qualitative design using interviews and focus groups (n=45) and an epidemiological design which included applying the Montenegro test (n=251), uncovering suspected cases of cutaneous leishmaniasis in humans, (n=5) and applying epidemiological surveys (n=409). Among the results, a lack of knowledge regarding the vector was found; although respondents could identify the Lutzomyia (known as "alú"), they did not correlate it with cutaneous leishmaniasis. In addition, traditional home treatments were more frequently used, increasing the underrecording of cases. With respect to healthcare personnel, flaws in diagnosis and treatment were found, which reinforces adherence to home treatments. This scenario calls for a reflection upon the challenges of the health care system in relation to the interventions of health personnel in communities situated in endemic areas.

La ciudad fue creada para que hombres y mujeres construyeran sus proyectos de vida en medio del Desierto de Atacama, ofreciéndoles todas las garantías y la infraestructura para que ello fuese así en los marcos de una política de pleno empleo, de modo de contener a la población en un medio inhóspito, cumplir los objetivos productivos y fortalecer una identidad coherente y cohesionada, lo que a partir de nuevas decisiones estratégicas es substituido por un modelo de flexibilidad laboral, lo que anula su definición primigenia y el interés colectivo para comenzar a dar paso a un campamento minero.In this paper we look into the relationship between the nitrate town of Maria Elena (in Region II - designed on Utopian principals as a private project - and the changing labor relations between the SQM Company and the workers as a result of the predominance of a new accumulation model guided by competitiveness, quality production and globalization. The town was created so that men and women could establish their livelihoods in the Atacama Desert, with guarantees and infrastructure based on a full employment policy. This was in order to anchor the population in this inhospitable environment, to meet production objectives and to strengthen a coherent and cohesive identity. New strategic decisions led to this model being replaced by one based on labour flexibilization, deleting its original intention and collective interest to give way to a mining camp.

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.

    The objects of the empirical science known as particle physics are not like objects ordinarily conceived. Physicists' particles can enter states strangely entangled with those of other particles; they can obey statistics which suggest that they lack genidentity; their properties (some think) are created in measurement, or (others think) can only be limned from the symmetries of the theory describing them. 'The implications of contemporary physical theories for the debate on the nature of objects' provides 'the central theme' (p. 4) of Interpreting Bodies, editor Elena Castellani's new collection of essays. Contributions to the volume vary dramatically in vintage (Born's and Reichenbach's are well into middle age; others appear here for the first time); in approach (the collection includes Giuliano Toraldo diFrancia's nine-page history of the object concept from Democritus to d'Espagnat, Peter Mittelstaedt's discussion of the Kantian constitution of quantum objects, and Giulo Peruzzi's explication of the scattering cross section and its role in experimental particle physics); and in intended audience. Lacking the space to treat each contribution in turn, I will focus on those dealing with the problem of the One and the Many.

  11. Compositional diversity in peridotites as result of a multi-process history: The Pacific-derived Santa Elena ophiolite, northwest Costa Rica

    2015-08-01

    The Santa Elena ophiolite (SEO) is an ultramafic nappe of more than 270 km2 overlying a tectonic serpentinite-matrix mélange in northwest Costa Rica. It is mainly composed of Cpx-rich and Cpx-poor harzburgites (~ 2.5 km-thick), with minor lherzolite, dunite and chromitite, as well as intrusive mafic sills and subvertical dikes, which coalesce into an upper Isla Negritos gabbroic sill complex. Minerals and whole-rock features of the Cpx-rich and Cpx-poor harzburgites share features of the abyssal and supra-subduction zone (SSZ) peridotites, respectively. To explain these characteristics two-stages of melting and refertilization processes are required. By means of trace element modeling, the composition of Cpx-rich harzburgites may be reproduced by up to ~ 5-10% melting of a primitive mantle source, and the composition of Cpx-poor harzburgites and dunites by ~ 15-18% melting of an already depleted mantle. Therefore, the Cpx-rich harzburgites can be interpreted as product of first-stage melting and low-degrees of melt-rock interaction in a mid-ocean ridge environment, and the Cpx-poor harzburgites and dunites as the product of second-stage melting and refertilization in a SSZ setting. The mafic sills and the Isla Negrito gabbros are genetically related and can be explained as crystallization from the liquids that were extracted from the lower SSZ mantle levels and emplaced at shallow conditions. The Murciélagos Island basalts are not directly related to the ultramafic and mafic rocks of the SEO. Their E-MORB-like composition is similar to most of the CLIP mafic lavas and suggests a common Caribbean plume-related source. The SEO represents a fragment of Pacific-derived, SSZ oceanic lithosphere emplaced onto the southern North America margin during the late Cretaceous. Because of the predominance of rollback-induced extension during its history, only a limited amount of crustal rocks were formed and preserved in the SEO.

    2008-01-01

    Full Text Available This work tries to demonstrate that the social construction of the national hero/heroine as a symbol of courage and resistance generally arises within a period of social, political, and economic crisis. The national hero is a construction that is created in a moment characterized by the loss of public trust and the failure of government leaders to act. The creation of the heroic image functions as a sociopolitical tool. The article suggests that there is a close relationship between the history and the construction of heroic fgures. Using the death of Peruvian activist María Elena Moyano as a concrete example, it demonstrates that journalistic discourse has the ability to create an heroic image around a person who has been given the traditional role that the hero has played in society since Antiquity.

    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.

    To make known, comprehensively, an almost unknown episode in the life of Dr. Francisco Diaz (1527-1590), surgeon of the king Philip II, and author of the first urology treaty in the history of medicine. To our knowledge, to date there were few references about the participation that, as an expert, Francisco Diaz had to have in the inquisitorial process against Elena de Cespedes, a presumed hermaphrodite accused by the Inquisition because being a woman married another one pretending to be a man. The trial was carried out in Toledo in 1587 and had great impact in that time, because the accused, dressing with male clothes and usurping the prerogatives of a man, had gotten by fraud titles and favours which were forbidden for women, the title of surgeon among them. Except for the reference by Folch Jou and Burshatin, both short and incomplete, no other author or biographer of the famous surgeon had cited this episode of his life, which to our judgment could mean a great damage to his reputation. We reviewed the works by the two aforementioned authors, all the works and biographies about Dr. Francisco Diaz that we could found, and microfilmed and transcript the whole bundle 234, expedient 24, from the section Inquisition at the National Historical Archive in Madrid, corresponding to Elena de Cespedes (alias Eleno) (> 500 pages) to obtain the greatest amount of data about the accused and the performance of Dr. Francisco Diaz. Francisco Diaz was requested, as an expert, by the Vicar of Madrid to perform the examination of the genitourinary organs to give or not marriage license to that woman saying she was a man. In his report in the year 1586, surprisingly the urologist declared that the petitioner was a man. As it would be demonstrated during the trial, the accused, who alleged being hermaphrodite in her defense, had been able to deceive the expert with her tricks altering her genital morphology. Thanks to her surgical knowledge she had mutilated herself surgically

En este trabajo discutimos la pertinencia de considerar la información generada más allá de un ANP para elaborar e implementar su programa de manejo con una perspectiva de conservación regional; esto, a través de un ejercicio de comparación de la información generada sobre la avifauna dentro y fuera del ANP. En este marco, presentamos los avances en el conocimiento de la diversidad de aves en el bosque templado del Rancho Santa Elena (RSE, un conjunto predial ubicado en la Sierra de las Navajas, próximo al Parque Nacional El Chico (PNEC, en el estado de Hidalgo, México. Desde 2005 a la fecha hemos registrado 90 especies de aves a partir de muestreos con redes de niebla, del recorrido no sistemático de senderos y de observaciones incidentales. Estimamos que esta riqueza de especies representa aproximadamente el 70% de la riqueza esperada en el sitio. En contraste, en el PNEC se han registrado 74 especies desde 1974, de las cuales al menos ocho representan registros incorrectos o probablemente incorrectos. Asimismo, en el RSE hemos registrado una mayor diversidad de gremios trófico-conductuales y de especies endémicas a México que las registradas en el PNEC. Los inventarios y la generación de conocimiento más allá de las ANP pueden ser insumos importantes en la definición e implementación de sus estrategias de manejo, las cuales deben tener una perspectiva de conservación regional.

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.

    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

El objetivo principal del presente artículo es avanzar en la discusión sobre los impactos sociales del cambio tecnológico en el este y sur de la provincia de Córdoba, analizando en particular sus efectos sobre el rol de la mujer en la agricultura. A partir de una perspectiva ecofeminista, el trabajo aporta evidencia empírica sobre distintos aspectos relacionados con la población, el empleo y el bienestar. Las principales conclusiones indican que, a pesar del fuerte desarrollo alcanzado por el sector agropecuario, la posición de las mujeres del campo cordobés no parece haberse visto promovida o fortalecida, ya que, en general, la mujer rural continúa relegada a un papel secundario y marginada al rol de 'esposa del productor'.During the last decades, the Argentine agricultural sector has been characterized by a rapid and profound technological transformation. The main goal of this paper is to foster a discussion about the social impacts of technological change in the southern and eastern regions of the province of Cordoba focusing, in particular, on its repercussions on farm women and their role in agriculture. Based on an ecofeminist perspective, this study presents empirical evidence about various aspects related to population, employment and welfare. Our main conclusions show that, in spite of the remarkable development achieved by the agricultural sector, the position of Cordoba farm women does not seem to have been promoted or strengthened, since, in general, rural women continue to be relegated to a secondary role and categorized as 'farmer's wives'.

    This report on the natural gas industry of Canada includes: composition and uses of natural gas, production statistics, exploration and development, reserve estimates, natural gas processing, transportation, and marketing. For the Canadian natural gas industry, 1966 was a year of moderate expansion in all phases, with a strong demand continuing for sulfur and liquid hydrocarbons produced as by-products of gas processing. Value of natural gas production increased to $199 million and ranked sixth in terms of value of mineral ouput in Canada. Currently, natural gas provides over 70% of Canada's energy requirements. Proved remaining marketable reserves are estimated to be in excess of a 29-yr supply.

  2. Gordimer’s rendition of the picaresque in A Sport of Nature

    Directory of Open Access Journals (Sweden)

    M. Wenzel

    1993-05-01

    Full Text Available The aim of this article is twofold: firstly, to explore the picaresque elements present in Nadine Gordimer’s A Sport of Nature and secondly, to relate them to her more pronounced stance on feminism which has evolved since the 1980s. I suggest that an appropriate reading strategy would not only foreground these issues but also highlight A Sport of Nature as one of her most underrated novels. Following the example of the Latin American authors Isabel Allende and Elena Poniatowska, Cordimer has appropriated the picaresque tradition as an ideal vehicle to depict the elements of social critique and feminist assertion which characterize A Sport of Nature. The ironic retrospective stance on society, conventionally represented by a picaro as a social outcast, is reinforced by the introduction of a picara, thereby underlining the double marginalization of women as subjects and sexual objects. I propose that a feminist-oriented reading of the text which recognizes this subversive quality, would lend a different dimension to its interpretation. The character of Hillela serves as an implicit example of female ingenuity which attains political equality through devious means despite, and as a result of, the constraints of a hypocritical society and an entrenched patriarchal system. Seen from this perspective, the seemingly disparate elements of the novel coalesce to present a damning picture of contemporary society.

  6. Temporal naturalism

    Science.gov (United States)

    Smolin, Lee

    2015-11-01

    Two people may claim both to be naturalists, but have divergent conceptions of basic elements of the natural world which lead them to mean different things when they talk about laws of nature, or states, or the role of mathematics in physics. These disagreements do not much affect the ordinary practice of science which is about small subsystems of the universe, described or explained against a background, idealized to be fixed. But these issues become crucial when we consider including the whole universe within our system, for then there is no fixed background to reference observables to. I argue here that the key issue responsible for divergent versions of naturalism and divergent approaches to cosmology is the conception of time. One version, which I call temporal naturalism, holds that time, in the sense of the succession of present moments, is real, and that laws of nature evolve in that time. This is contrasted with timeless naturalism, which holds that laws are immutable and the present moment and its passage are illusions. I argue that temporal naturalism is empirically more adequate than the alternatives, because it offers testable explanations for puzzles its rivals cannot address, and is likely a better basis for solving major puzzles that presently face cosmology and physics. This essay also addresses the problem of qualia and experience within naturalism and argues that only temporal naturalism can make a place for qualia as intrinsic qualities of matter.

    2014-06-01

    Full Text Available This special issue of the Nordic Journal of Science and Technology Studies is interested in how nature, in different versions and forms, is invited into our studies, analyses, and stories. How is it that we “write nature”? How is it that we provide space for, and actually describe the actors, agents, or surroundings, in our stories and analyses? The articles in the issue each deal with different understandings of both the practices of writing and the introduction of various natures into these. In this introduction to the issue the editors engage with actor-network theory as a material semiotic resource for writing nature. We propose to foreground actor-network theory as a writing tool, at the expense of actor-network theory as a distinct vocabulary. In doing this and pointing out the semiotic origins to material-semiotics we also want to problematize a clear-cut material approach to writing nature.

    The search for a remedy or a prescription that can enhance sexual function and/or treat male erectile dysfunction has been an obsession throughout known history. Whether it was an Eastern civilization or a Western one, religious or atheist, man's aspiration for a better or best "manhood" has been a history-time goal. This review will discuss the current research done on the most popular natural aphrodisiacs and examine the weight of evidence to support or discourage the use of any of these substances to enhance sexual desire and/or function. Review of the current evidence on the use of natural substances as aphrodisiacs. Efficacy of natural aphrodisiacs in enhancing sexual function in men and women. There is little evidence from literature to recommend the usage of natural aphrodisiacs for the enhancement of sexual desire and/or performance. Data on yohimbine's efficacy does not support the wide use of the drug, which has only mild effects in the treatment of psychogenic ED. Although there's a positive trend towards recommending ginseng as an effective aphrodisiac, however, more in depth studies involving large number of subjects and its mechanism of action are needed before definite conclusions could be reached. Data on the use of natural aphrodisiacs in women is limited. The current body of objective evidence does not support the use of any natural aphrodisiac as an effective treatment for male or female sexual dysfunctions.

Arguably, these modelling practices are ripe with the anticipation of nature. They aspire to pre-empt it, hence expect it to be ‘out there’, and ultimately work through formalized distillations...... of it – hydrodynamic equations – which have their own anticipations and place their own demands on their modellers. Through the experience of a flood modelling apprenticeship I argue that the taking-place of such anticipations paradoxically relies on the birth of a hybrid, the model-modeller, and thus on a nature...

    Full Text Available A serological screening was performed in 615 individuals aged 0-87 years, living in the city of Cordoba, Argentina to study the relationship between antibody prevalence for the SLE virus and age. A 13.98% prevalence of neutralizing antibodies was obtained and its relation to age was significantly high (p = 0.045. The highest seroprevalence was noted on individuals over 60 years old (>20%, whereas no subject under 10 was seropositive for this virus. Our results confirm that the agent is endemic in this area and neurological pathology studies should be performed on those individuals aged 60 since they represent the most susceptible group to SLE virus.Com a finalidade de estudar a relação entre prevalência de anticorpo para o vírus da encefalite St. Louis (ESL e a idade, foram analisados 615 soros de indivíduos entre 0-87 anos de idade, morando na cidade de Córdoba, Argentina. Detectou-se uma prevalência de anticorpos neutralizantes de 13,98% e observou-se uma relação com a idade estatisticamente significante (p = 0,045. A soroprevalência mais alta foi encontrada em indivíduos de mais de 60 anos (> 20%, enquanto nenhum com menos de 10 anos foi soropositivo para este vírus. Nossos resultados confirmam que o agente é endêmico nesta área. Por esse motivo os autores sugerem que deveríam se realizar estudos de patologias neurológicas nesses indivíduos de 60 anos de idade dado que eles representam o grupo mais suscetível ao vírus ESL.

    A course of a game is formulated as a physical process that will consume free energy in the least time. Accordingly, the rate of entropy increase is the payoff function that will subsume all forms of free energy that motivate diverse decisions. Also other concepts of game theory are related to their profound physical counterparts. When the physical portrayal of behavior is mathematically analyzed, the course of a game is found to be inherently unpredictable because each move affects motives in the future. Despite the non-holonomic character of the natural process, the objective of consuming free energy in the least time will direct an extensive-form game toward a Lyapunov-stable point that satisfies the minimax theorem. -- Highlights: → Behavior in the context of game theory is described as a natural process. → The rate of entropy increase, derived from statistical physics of open systems, is identified as the payoff function. → Entropy as the payoff function also clarifies motives of collaboration and subjective nature of decision making. → Evolutionary equation of motion that accounts for the course of a game is inherently unpredictable.

    14 C dates between 600 and 900 AD were obtained for early Iron Age sites in Natal, and from 1300 to 1450 AD for rock engraving sites in Bushmanland. Palaeoenvironmental data derived from the dating of samples related to sedimentary and geomorphic features in the central and northern Namib Desert enabled the production of a tentative graph for the changes in humidity in the region over the past 40000 years. These results suggest that relatively humid conditions came to an end in the Namib at ±25000 BP (before present). The increased precision of the SIRA mass spectrometer enabled the remeasurement of 13 C and 18 O in the Cango stalagmite. This data confirmed that the environmental temperatures in the Southern Cape remained constant to within ±1 o C during the past 5500 years. Techniques and applications for environmental isotopes in hydrology were developed to determine the origin and movement of ground water. Isotopic fractionation effects in light elements in nature were investigated. The 15 N/ 14 N ratio in bones of animals and humans increases in proportion to the aridity of the environment. This suggests that 15 N in bone from dated archaeological sites could be used to detect changes in past climatic conditions as naturally formed nitrate minerals are higly soluble and are only preserved in special, very dry environments. The sources and sinks of CO 2 on the South African subcontinent were also determined. The 13 C/ 12 C ratios of air CO 2 obtained suggest that the vegetation provides the major proportion of respired CO 2 . 9 refs., 1 fig

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. The aim of this contribution is to recognize the effect of fire on the lichen community of Sierra Chaco in Cordoba province. Two areas were selected, one without past fire and the other with fire in 1996. Coverage and presence of lichen species on trees and shrubs were recorded in the two areas using systematic, standardized sampling. Diversity and coverage of lichens is similar between the two areas but composition varies. The lichen species in the burned area are

Los resultados indican niveles bajos de participación social y política, con una fuerte presencia de actividades sociales de corte religioso, por sobre otros tipos de participación. Asimismo, se realizó un análisis cualitativo acerca de las razones que los niños y niñas explicitan en relación con su ausencia de participación. A partir de los resultados se han observado en las prácticas y discursos infantiles la reproducción de enunciados que los desacreditan como sujetos de derechos con capacidad de acción política. Esta situación imposibilita la emergencia protagónica de los niños y niñas en el área de lo público.

The results indicate low levels of social and political participation with a strong presence of social activities of religious cut, above other types of participation. A qualitative analysis about the reasons that children brought in relationship with its absence of participation is also conducted. Based on the results it has been observed in practices and children’s speech reproduction statements discrediting them as subjects of rights capable of political action.

    Sigurdson, Gregory T; Tang, Peipei; Giusti, M Mónica

    2017-02-28

    The color of food is often associated with the flavor, safety, and nutritional value of the product. Synthetic food colorants have been used because of their high stability and low cost. However, consumer perception and demand have driven the replacement of synthetic colorants with naturally derived alternatives. Natural pigment applications can be limited by lower stability, weaker tinctorial strength, interactions with food ingredients, and inability to match desired hues. Therefore, no single naturally derived colorant can serve as a universal alternative for a specified synthetic colorant in all applications. This review summarizes major environmental and biological sources for natural colorants as well as nature-identical counterparts. Chemical characteristics of prevalent pigments, including anthocyanins, carotenoids, betalains, and chlorophylls, are described. The possible applications and hues (warm, cool, and achromatic) of currently used natural pigments, such as anthocyanins as red and blue colorants, and possible future alternatives, such as purple violacein and red pyranoanthocyanins, are also discussed.

    2014-02-01

    Full Text Available  The goal of this paper is to sketch an empiricist metaphysics of laws of nature. The key idea is that there are regularities without regularity-enforcers. Differently put, there are natural laws without law-makers of a distinct metaphysical kind. This sketch will rely on the concept of a natural pattern and more significantly on the existence of a network of natural patterns in nature. The relation between a regularity and a pattern will be analysed in terms of mereology.  Here is the road map. In section 2, I will briefly discuss the relation between empiricism and metaphysics, aiming to show that an empiricist metaphysics is possible. In section 3, I will offer arguments against stronger metaphysical views of laws. Then, in section 4 I will motivate nomic objectivism. In section 5, I will address the question ‘what is a regularity?’ and will develop a novel answer to it, based on the notion of a natural pattern. In section 6, I will raise the question: ‘what is a law of nature?’, the answer to which will be: a law of nature is a regularity that is characterised by the unity of a natural pattern.

During the talk we will present results of scientific review, analysis and synthesis, which emphasize same new trends in communication of the natural hazards theories and practices within an up-to-the-minute context of new environmental and climate change issues, new technologies, and a new focus on resiliency. The presentation is divided into five sections that focus on natural hazards communication in terms of education, risk management, public discourse, engaging the public, theoretical perspectives, and new media. It includes results of case studies and best practices. It delves into natural hazards communication theories, including diffusion, argumentation, and constructivism, to name a few. The presentation will provide information about: (1) A manual of natural hazards communication for scientists, policymakers, and media; (2) An up-to-the-minute context of environmental hazards, new technologies & political landscape; (3) A work by natural hazards scientists for geoscientists working with social scientists and communication principles; (4) A work underpinned by key natural hazards communication theories and interspersed with pragmatic solutions; (5) A work that crosses traditional natural hazards boundaries: international, interdisciplinary, theoretical/applied. We will further explore how spatial planning can contribute to risk governance by influencing the occupation of natural hazard-prone areas, and review the central role of emergency management in risk policy. The goal of this presentation is to contribute to the augmentation of the conceptual framework

  2. Nature of the Yucatan Block Basement as Derived From Study of Granitic Clasts in the Impact Breccias of Chicxulub Crater

    The tectonic and petrologic nature of the basement of the Yucatan Block is studied from analyses of basement clasts present in the impact suevitic breccias of Chicxulub crater. The impact breccias have been sampled as part of the drilling projects conducted in the Yucatan peninsula by Petroleos Mexicanos, the National University of Mexico and the Chicxulub Scientific Drilling Project. Samples analyzed come mainly from the Yaxcopoil-1, Tekax, and Santa Elena boreholes, and partly from Pemex boreholes. In this study we concentrate on clasts of the granites, granodiorites and quartzmonzonites in the impact breccias. We report major and trace element geochemical and petrological data, which are compared with data from the granitic and volcanic rocks from the Maya Mountains in Belize and from the Swannee terrane in Florida. Basement granitic clasts analyzed present intermediate to acidic sub-alkaline compositions. Plots of major oxides (e.g., Al2O3, Fe2O3, TiO2 and CaO) and trace elements (e.g., Th, Y, Hf, Nb and Zr) versus silica allow separation of samples into two major groups, which can be compared to units in the Maya Mountains and in Florida basement. The impact suevitic breccia samples have been affected by alteration likely related to the hydrothermal processes associated with the crater melt sheet. Cloritization, seritization and fenitization alterations are recognized, due to the long term hydrothermalism. Krogh et al. (1993) reported U-Pb dates on zircons from the suevitic breccias, which gave dates of 545 +/- 5 Ma and 418 +/- 6 Ma, which were interpreted in terms of the deep granitic metamorphic Yucatan basement. The younger date correlates with the age for the Osceola Granite and the St. Lucie metamorphic complex of the Swannee terrane in the Florida peninsula. The intrusive rocks in the Yucatan basement may be related to approx. 418 Ma ago collisional event in the Late Silurian.

    2012-01-01

    Naturally occurring antimicrobial compounds could be applied as food preservatives to protect food quality and extend the shelf life of foods and beverages. These compounds are naturally produced and isolated from various sources, including plants, animals and microorganisms, in which they constitute part of host defense systems. Many naturally occurring compounds, such as nisin, plant essential oils, and natamycin, have been widely studied and are reported to be effective in their potential role as antimicrobial agents against spoilage and pathogenic microorganisms. Although some of these natural antimicrobials are commercially available and applied in food processing, their efficacy, consumer acceptance and regulation are not well defined. This manuscript reviews natural antimicrobial compounds with reference to their applications in food when applied individually or in combination with other hurdles. It also reviews the mechanism of action of selected natural antimicrobials, factors affecting their antimicrobial activities, and future prospects for use of natural antimicrobials in the food industry.

  15. On nature and bioethics.

    Science.gov (United States)

    Peterson, Paul Silas

    2010-01-01

    The account of nature and humanity's relationship to nature are of central importance for bioethics. The Scientific Revolution was a critical development in the history of this question and many contemporary accounts of nature find their beginnings here. While the innovative approach to nature going out of the seventeenth century was reliant upon accounts of nature from the early modern period, the Middle Ages, late-antiquity and antiquity, it also parted ways with some of the understandings of nature from these epochs. Here I analyze this development and suggests that some of the insights from older understandings of nature may be helpful for bioethics today, even if there can be no simple return to them.

    1998-01-01

    An overview of natural gas markets in Canada and in the United States was provided. The major factors that determine the direction of natural gas prices were depicted graphically. Price volatility has decreased in recent months. As expected, April through November total energy consumption reached historically high levels. Demand for natural gas during the summer of 1997 was not as strong as anticipated. Nuclear energy appears to be on the slippery slope, with natural gas-driven electricity projects to fill the void. Hydroelectricity had a strong showing in 1997. Prospects are less bright for 1998 due to above average temperatures. Canadian natural gas export capacity has increased 5.5 times between 1986 and estimated 1999 levels. Despite this, in 1997, deliveries to the United States were marginally behind expectations. Natural gas consumption, comparative fuel prices, natural gas drilling activity, natural gas storage capacity, actual storage by region, and average weekly spot natural gas prices, for both the U. S. and Canada, were also provided. With regard to Canada, it was suggested that Canadian producers are well positioned for a significant increase in their price realization mostly because of the increase in Canada's export capacity in 1997 (+175 Mmcf/d), 1998 (1,060 Mmcf/d) and potentially in 1999 or 2000, via the Alliance Pipeline project. Nevertheless, with current production projections it appears next to impossible to fill the 10.9 Bcf/d of export capacity that will be potentially in place by the end of 1999. tabs., figs

    2016-01-01

    The manufacture and sale of natural products constitute a multi-billion dollar industry. Nearly a third of the American population admit to using some form of complementary or alternative medicine, with many using them in addition to prescription medications. Most patients fail to inform their healthcare providers of their natural product use and physicians rarely inquire. Annually, thousands of natural product-induced adverse events are reported to Poison Control Centers nationwide. Natural product manufacturers are not responsible for proving safety and efficacy, as the FDA does not regulate them. However, concerns exist surrounding the safety of natural products. This review provides details on natural products that have been associated with renal dysfunction. We have focused on products that have been associated with direct renal injury, immune-mediated nephrotoxicity, nephrolithiasis, rhabdomyolysis with acute renal injury, hepatorenal syndrome, and common adulterants or contaminants that are associated with renal dysfunction. The potential for natural products to cause renal dysfunction is justifiable. It is imperative that natural product use be monitored closely in all patients. Healthcare practitioners must play an active role in identifying patients using natural products and provide appropriate patient education. © 2016 S. Karger AG, Basel.

    1985-01-01

    In 1954, Professor Kazuo, Kuroda of Arkansas University in USA published the possibility that spontaneously generated natural nuclear reactors existed in prehistoric age. In 1972, 18 years after that, Commissariat a l'Energie Atomique published that in the Oklo uranium deposit in Gabon, Africa, a natural nuclear reactor was found. This fact was immediately informed to the whole world, but in Japan, its details have not necessarily been well known. The chance of investigating into this fact and visiting the Oklo deposit by the favor of COMUF, the owner of the Oklo deposit, was given, therefore, the state of the natural reactors, which has been known so far, is reported. At present, 12 natural reactors have been found in the vicinity of the Oklo deposit. The natural reactors were generated spontaneously in uranium deposits about 1.7 billion years ago when the isotopic abundance of U-235 was 3 %, and the chain reaction started naturally. When the concentration of U-235 lowered, the reaction stopped naturally. The abnormality in the U-235 abundance in natural uranium was found, and the cause was pursued. The evidence of the existence of natural reactors was shown. (Kako, I.)

    Finnish natural gas usage topped the 3.3 billion cubic metre mark last year, up 3.6 % on the 1994 figure. Growth has increased now for 12 years in a row. Thanks to offtake by large individual users, the pipeline network has been expanded from South-East Finland to the Greater Helsinki area and central southern Finland. Natural gas plays a much larger role in this region than the 10 % accounted for by natural gas nationally would indicate. The growth in the share of Finland's energy use accounted for by natural gas has served to broaden the country's energy supply base. Natural gas has replaced coal and oil, which has considerably reduced the level of emissions resulting form energy generation

    2014-06-01

    Quayshawn Spencer (2014) misunderstands my treatment of racial naturalism. I argued that racial naturalism must entail a strong claim, such as "races are subspecies", if it is to be a substantive position that contrasts with anti-realism about biological race. My recognition that not all race naturalists make such a strong claim is evident throughout the article Spencer reviews (Hochman, 2013a). Spencer seems to agree with me that there are no human subspecies, and he endorses a weaker form of racial naturalism. However, he supports his preferred version of 'racial naturalism' with arguments that are not well described as 'naturalistic'. I argue that Spencer offers us an unnaturalised racial naturalism.

  18. "Diseases and natural kinds".

    Science.gov (United States)

    Sulmasy, Daniel P

    2005-01-01

    David Thomasma called for the development of a medical ethics based squarely on the philosophy of medicine. He recognized, however, that widespread anti-essentialism presented a significant barrier to such an approach. The aim of this article is to introduce a theory that challenges these anti-essentialist objections. The notion of natural kinds presents a modest form of essentialism that can serve as the basis for a foundationalist philosophy of medicine. The notion of a natural kind is neither static nor reductionistic. Disease can be understood as making necessary reference to living natural kinds without invoking the claim that diseases themselves are natural kinds. The idea that natural kinds have a natural disposition to flourish as the kinds of things that they are provides a telos to which to tether the notion of disease - an objective telos that is broader than mere survival and narrower than subjective choice. It is argued that while nosology is descriptive and may have therapeutic implications, disease classification is fundamentally explanatory. Sickness and illness, while referring to the same state of affairs, can be distinguished from disease phenomenologically. Scientific and diagnostic fallibility in making judgments about diseases do not diminish the objectivity of this notion of disease. Diseases are things, not kinds. Injury is a concept parallel to disease that also makes necessary reference to living natural kinds. These ideas provide a new possibility for the development of a philosophy of medicine with implications for medical ethics.

  19. Almacenamiento de gas natural

    Full Text Available The largest reserves of natural gas worldwide are found in regions far of main cities, being necessary different alternatives to transport the fluid to the consumption cities, such as pipelines, CNG or ships, LNG, depending on distances between producing regions and demanding regions and the producing volumes. Consumption regions have three different markets to naturalgas; residential and commercial, industrial and power generation sector. The residential and commercial is highly seasonal and power generation sector is quite variable depending on increases of temperature during summer time. There are also external issuesthat affect the normal gas flow such as fails on the national system or unexpected interruptions on it, what imply that companies which distribute natural gas should design plans that allow supplying the requirements above mentioned. One plan is using underground natural gas storage with capacities and deliverability rates enough to supply demands. In Colombia there are no laws in this sense but it could be an exploration to discuss different ways to store gas either way as underground natural gas storage or above superficies. Existing basically three different types of underground natural gas storage; depleted reservoirs, salt caverns and aquifers. All ofthem are adequate according to geological characteristics and the needs of the distributors companies of natural gas. This paper is anexploration of technical and economical characteristics of different kind of storages used to store natural gas worldwide.

  20. Natural gas in Mexico

    A series of overhead viewgraphs accompanied this presentation which focused on various aspects of the natural gas industry in Mexico. Some of the viewgraphs depicted statistics from 1998 regarding natural gas throughput from various companies in North America, natural gas reserves around the world, and natural gas reserves in Mexico. Other viewgraphs depicted associated and non-associated natural gas production from 1988 to 1998 in million cubic feet per day. The Burgos Basin and the Cantarell Basin gas production from 1997 to 2004 was also depicted. Other viewgraphs were entitled: (1) gas processing infrastructure for 1999, (2) cryogenic plant at Cd. PEMEX, (3) average annual growth of dry natural gas production for 1997-2004 is estimated at 5.2 per cent, (4) gas flows for December 1998, (5) PGPB- interconnect points, (6) U.S. Mexico gas trade for 1994-1998, (7) PGPB's interconnect projects with U.S., and (8) natural gas storage areas. Technological innovations in the industry include more efficient gas turbines which allow for cogeneration, heat recovery steam generators which reduce pollutant emissions by 21 per cent, cold boxes which increase heat transfer efficiency, and lateral reboilers which reduce energy consumption and total costs. A pie chart depicting natural gas demand by sector shows that natural gas for power generation will increase from 16 per cent in 1997 to 31 per cent in 2004. The opportunities for cogeneration projects were also reviewed. The Comision Federal de Electricidad and independent power producers represent the largest opportunity. The 1997-2001 investment program proposes an 85 per cent sulphur dioxide emission reduction compared to 1997 levels. This presentation also noted that during the 1998-2001 period, total ethane production will grow by 58 tbd. 31 figs

    The demand for nuclear fuel to supply the nuclear plants within the ECC (31,200 MW at the end of last year) totalled nearly 9,600 tons of natural uranium and 4,900 of separation work units (SWU). Once reactors currently under construction come into service, the demand for natural uranium will reach 13,200 tons by 1985 and that for SWUs to 8,600. If one takes the years 1981 to 1985, total natural uranium needs during this period will be 56,300 tons and those for SWUs 35.100 [fr

    In the recent article, "Against the New Racial Naturalism", Adam Hochman (2013, p. 332) argues that new racial naturalists have been too hasty in their racial interpretation of genetic clustering results of human populations. While Hochman makes a number of good points, the purpose of this paper is to show that Hochman's attack on new racial naturalists is misguided due to his definition of 'racial naturalism'. Thus, I will show that Hochman's critique is merely a consequence of an unnatural interpretation of racial naturalism. Copyright © 2014 Elsevier Ltd. All rights reserved.

    The concept of natural deductions was investigated by the author in his analysis of the complexity of deductions in propositional computations (1975). Here some natural deduction systems are considered, and an analytical procedure proposed which results in a deduction diagram for each system. Each diagram takes the form of an orientated, charge graph, features of which can be used to establish the equivalence of classes of deductions. For each of the natural deduction systems considered, a system of equivalent transformation schemes is derived, which is complete with respect to the given definition of equivalence. 2 references.

    1993-01-01

    Natural gas pricing is the heart and soul of the gas business. Price specifically affects every phase of the industry. Too low a price will result in short supplies as seen in the mid-1970s when natural gas was scarce and in tight supply. To fully understand the pricing of this energy commodity, it is important to understand the total energy picture. In addition, the effect and impact of world and US economies, and economics in general are crucial to understanding natural gas pricing. The purpose of this presentation will be to show the parameters going into US natural gas pricing including the influence of the many outside industry factors like crude oil and coal pricing, market drivers pushing the gas industry, supply/demand parameters, risk management for buyers and sellers, and other elements involved in pricing analysis

    1996-01-01

    This article presents compressed natural gas for vehicles (CNG), which can provide considerable advantages both as an alternative fuel and as a clean fuel. These assets are not only economic but also technical. The first part deals with what is at stake in developing natural gas as a motor fuel. The first countries to use CNG were those with natural gas resources in their subsoil. Today, with a large number of countries having to cope with growing concern about increasing urban pollution, natural gas is also seen as a clean fuel that can help cut vehicle pollutant emissions dramatically. In the second part a brief technical descriptions is given of CNG stations and vehicles, with the aim of acquainting the reader with some of CNG's specific technical features as compared to gasoline and diesel oil. Here CNG technologies are seen to be very close to the more conventional ones. (author)

    2018-04-01

    The dependence of the natural amplitudes of the harmonium atom in its ground state on the confinement strength ω is thoroughly investigated. A combination of rigorous analysis and extensive, highly accurate numerical calculations reveals the presence of only one positive-valued natural amplitude ("the normal sign pattern") for all ω ≥1/2 . More importantly, it is shown that unusual, weakly occupied natural orbitals (NOs) corresponding to additional positive-valued natural amplitudes emerge upon sufficient weakening of the confinement. These solitonic NOs, whose shapes remain almost invariant as their radial positions drift toward infinity upon the critical values of ω being approached from below, exhibit strong radial localization. Their asymptotic properties are extracted from the numerical data and their relevance to calculations on fully Coulombic systems is discussed.

    Farmers are exposed to substantial weather and market related risks. Rational farmers seek to avoid large losses. Future climate change and energy price fluctuations therefore make adaptating to increased risks particularly important for them. Managing soil natural capital—the capacity of the soil...... to generate ecosystem services of benefit to farmers—has been proven to generate the double dividend: increasing farm profit and reducing associated risk. In this paper we explore whether managing soil natural capital has a third dividend: reducing the downside risk (increasing the positive skewness of profit......). This we refer to as the prudence effect which can be viewed as an adaptation strategy for dealing with future uncertainties through more prudent management of soil natural capital. We do this by developing a dynamic stochastic portfolio model to optimize the stock of soil natural capital—as indicated...

    Lesson "Balance in Nature" This simulation game-lesson (Balance in Nature) gives an opportunity for the students to show creativity, work independently, and to create models and ideas. It creates future-oriented thought connected to their experience, allowing them to propose solutions for global problems and personal responsibility for their activities. The class is divided in two teams. Each team chooses questions. 1. Question: Pollution in the environment. 2. Question: Care for nature and climate. The teams work on the chosen tasks. They make drafts, notes and formulate their solutions on small pieces of paper, explaining the impact on nature and society. They express their points of view using many different opinions. This generates alternative thoughts and results in creative solutions. With the new knowledge and positive behaviour defined, everybody realizes that they can do something positive towards nature and climate problems and the importance of individuals for solving global problems is evident. Our main goal is to recover the ecological balance, and everybody explains his or her own well-grounded opinions. In this work process the students obtain knowledge, skills and more responsible behaviour. This process, based on his or her own experience, dialogue and teamwork, helps the participant's self-development. Making the model "human↔ nature" expresses how human activities impact the natural Earth and how these impacts in turn affect society. Taking personal responsibility, we can reduce global warming and help the Earth. By helping nature we help ourselves. Teacher: Veselina Boycheva-Chapanova " Saint Patriarch Evtimii" Scholl Str.

    Rouhban, Badaoui

    Natural disaster loss is on the rise, and the vulnerability of the human and physical environment to the violent forces of nature is increasing. In many parts of the world, disasters caused by natural hazards such as earthquakes, floods, landslides, drought, wildfires, intense windstorms, tsunami, and volcanic eruptions have caused the loss of human lives, injury, homelessness, and the destruction of economic and social infrastructure. Over the last few years, there has been an increase in the occurrence, severity, and intensity of disasters, culminating with the devastating tsunami of 26 December 2004 in South East Asia.Natural hazards are often unexpected or uncontrollable natural events of varying magnitude. Understanding their mechanisms and assessing their distribution in time and space are necessary for refining risk mitigation measures. This second edition of Natural Hazards, (following a first edition published in 1991 by Cambridge University Press), written by Edward Bryant, associate dean of science at Wollongong University, Australia, grapples with this crucial issue, aspects of hazard prediction, and other issues. The book presents a comprehensive analysis of different categories of hazards of climatic and geological origin.

    This comprehensive Natural Resource Management Plan (NRMP) for Brookhaven National Laboratory (BNL) was built on the successful foundation of the Wildlife Management Plan for BNL, which it replaces. This update to the 2003 plan continues to build on successes and efforts to better understand the ecosystems and natural resources found on the BNL site. The plan establishes the basis for managing the varied natural resources located on the 5,265-acre BNL site, setting goals and actions to achieve those goals. The planning of this document is based on the knowledge and expertise gained over the past 15 years by the Natural Resources management staff at BNL in concert with local natural resource agencies including the New York State Department of Environmental Conservation, Long Island Pine Barrens Joint Planning and Policy Commission, The Nature Conservancy, and others. The development of this plan works toward sound ecological management that not only benefits BNL’s ecosystems but also benefits the greater Pine Barrens habitats in which BNL is situated. This plan applies equally to the Upton Ecological and Research Reserve (Upton Reserve). Any difference in management between the larger BNL area and the Upton Reserve are noted in the text.

    "The source of Man's unhappiness is his ignorance of Nature."D'Holbach believed that the misery he saw in mankind around him was caused by religion and its superstitious beliefs - that there was a God who controlled destiny and would reward or punish individuals. The System of Nature was written to replace these delusions with a schema of understanding based solely on the physical workings of nature. "Let Man study this nature, let him learn her laws, contemplate her energies." For d'Holbach the soul is only the physical body, understood from a certain point of view, which dies when the body dies. All the events and the nature of the world can be understood in terms of the motion and properties of matter; even the tiniest causes contribute to huge events - a simple change in the diet of an Emperor (or some other such insignificant cause), he suggests might have been capable of "saving kingdoms." For him, nature's laws are fixed and necessary, and if Man wants to find happiness it is best to accept this - if g...

  11. Natural gas prices

    International Nuclear Information System (INIS)

    Johnson, W.A.

    1990-01-01

    Since the 1970s, many electric utilities and industrial boiler fuel users have invested in dual fuel use capability which has allowed them to choose between natural gas, residual fuel oil, and in some instances, coal as boiler fuels. The immediate reason for this investment was the need for security of supply. Wellhead regulation of natural gas prices had resulted in shortages during the 1970s. Because many industrial users were given lowest priority in pipeline curtailments, these shortages affected most severely boiler fuel consumption of natural gas. In addition, foreign supply disruptions during the 1970s called into question the ready availability of oil. Many boiler fuel users of oil responded by increasing their ability to diversify to other sources of energy. Even though widespread investment in dual fuel use capability by boiler fuel users was initially motivated by a need for security of supply, perhaps the most important consequence of this investment was greater substitutability between natural gas and resid and a more competitive boiler fuel market. By the early 1980s, most boiler fuel users were able to switch from one fuel to another and often did for savings measured in pennies per MMBtu. Boiler fuel consumption became the marginal use of both natural gas and resid, with coal a looming threat on the horizon to both fuels

    2015-01-01

    Most clinical phytosterol studies are performed by adding purified supplements to smaller phytosterol amounts present in the natural diet. However, natural dietary phytosterols themselves may also have important effects on cholesterol metabolism. Epidemiological work using food frequency questionnaires to estimate dietary intake suggest that extremes of normal consumption may be associated with 3-14% changes in LDL cholesterol. Standardized food databases do not have enough phytosterol values to allow calculation of phytosterol intake for individuals outside of specialized studies. Natural diets contain phytosterol amounts ranging from less than 60 mg/2000 kcal to over 500 mg/2000 kcal. Physiological studies in which whole body cholesterol metabolism is investigated show large effects of natural dietary phytosterols on cholesterol absorption efficiency, cholesterol biosynthesis and cholesterol excretion which exceed the magnitude of changes in LDL cholesterol. The dual effects of natural phytosterols on both LDL-C and whole body cholesterol metabolism need to be considered in relating them to potential protection from coronary heart disease risk.

    Symmetry, disymmetry, chirality etc. are well-known topics in chemistry. But they cannot only be found on the molecular level of matter. Atoms and elementary particles in physics are also characterized by particular symmetry groups. Even living organisms and populations on the macroscopic level have functional properties of symmetry. The whole physical, chemical, and biological evolution seems to be regulated by the emergence of new symmetries and the breaking down of old ones. One is reminded of Heisenberg's famous statement: 'Die letzte Wurzel der Erscheinungen ist also nicht die Materie, sondern das mathematische Gesetz, die Symmetrie, die mathematische Form' (Wandlungen in den Grundlagen der Naturwissenschaften, 1959). Historically the belief in symmetry and simplicity of nature has a long philosophical tradition from the Pythagoreans, Plato and Greek astronomers to Kepler and modern scientists. Today, 'symmetries in nature' is a common topic of mathematics, physics, chemistry, and biology. A lot of Nobel prizes were given in honour of inquiries concerning symmetries in nature. The fascination of symmetries is not only motivated by science, but by art and religion too. Therefore 'symmetris in nature' is an interdisciplinary topic which may help to overcome C.P. Snow's 'Two Cultures' of natural sciences and humanities. (author) 17 refs., 21 figs

    Freedenthal, C.

    1993-01-01

    In recent years, natural gas has gained new momentum because of changes in marketing and regulations. The gas industry has always received an inordinate amount of regulatory control starting at the well head where the gas is produced to the consuming burner tip. Regulations have drastically impacted the availability of gas. Changes in the marketing and regulations have made the natural gas market sensitive at the point of production, the well head. Now, with plentiful supply and ease of transportation to bring the gas from the producing fields to the consumer, natural gas markets are taking advantage of the changed conditions. At the same time, new markets are developing to take advantage of the changes. This section shows consumers, especially the energy planners for large buyers of fuel, the advantages, sources and new methods of securing natural gas supplies. Background on how natural gas is produced and marketed are given. This section lists marketing sources, regulatory agencies and information groups available to help buyers and consumers of this important fuel for US industries and residences. 7 figs., 8 tabs

  16. Naturalness and Animal Welfare.

    Science.gov (United States)

    Yeates, James

    2018-04-05

    Naturalness is considered important for animals, and is one criterion for assessing how we care for them. However, it is a vague and ambiguous term, which needs definition and assessments suitable for scientific and ethical questions. This paper makes a start on that aim. This paper differentiates the term from other related concepts, such as species-typical behaviour and wellbeing. It identifies contingent ways in which naturalness might be used, as: (i) prompts for further welfare assessment; (ii) a plausible hypothesis for what safeguards wellbeing; (iii) a threshold for what is acceptable; (iv) constraints on what improvements are unacceptable; and (v) demarcating what is not morally wrong, because of a lack of human agency. It then suggests an approach to evaluating animals' behaviour that is quantitative, is based on reality, and which assesses naturalness by degrees. It proposes classing unaffected wild populations as natural by definition. Where animals might have been affected by humans, they should be compared to the closest population(s) of unaffected animals. This approach could allow us both to assess naturalness scientifically, and to make practical decisions about the behaviour of domestic animals.

  17. Natural gas deregulation

    International Nuclear Information System (INIS)

    Ronchi, M.

    1993-01-01

    With the aim of establishing realistic options for deregulation in the natural gas industry, this paper first considers the structural evolution of this industry and evidences how it differs from the petroleum industry with which it exhibits some essential characteristics in common. This comparison is made in order to stress that, contrary to popular belief, that which is without doubt good for the petroleum industry is not necessarily so also for the natural gas industry. The paper concludes with separate analyses of the natural gas markets in the principal industrialized countries. Arguments are provided to show that the 'soft' deregulation option for the natural gas industry is not feasible, and that 'total' deregulation instead, backed by the passing of a suitable package of anti-trust laws 'unbundling' the industry's four major activities, i.e., production, storage, primary and secondary distribution, is the preferable option. The old concept of guaranteed supplies for minor users of natural gas should give way to the laws of supply and demand governing inter-fuel competition ensured through the strict supervision of vigilance committees

    1993-01-01

    French CEA has reported in 1972 that natural nuclear reactors existed in Okulo uranium deposit in Gabon in Africa, that caused nuclear fission chain reaction (Okulo phenomena) spontaneously two billion years ago. The fission products and transuranic elements produced by the natural reactors have been preserved in strata without movement while subjected to geological phenomena for such very long years. 16 zones of the natural reactors have been discovered so far. The geological features of the Okulo uranium deposit are explained. The total amount of 235 U lost by the chain reaction was estimated to be about 6t, and the fission products were about 6t. The Okulo phenomena offered the valuable results of the synthetic formation disposal test that the nature has carried out for such long years. The significance of the study on natural analog is discussed. Organic substances and the mechanism of holding and movement of uranium and fission nuclides, the stability of uraninite and the age measurement of the deposit by Nd-Sm process are reported as the main results.

    The central conflicts of Stephen King’s horror novel The Shining are rooted in human nature and reflect evolutionarily recurrent adaptive problems—the problem of balancing conflicting evolved motives, such as motives for selfish status striving versus motives for affiliative nurturing behavior......, and the problem of surviving the hostile forces of nature. Moreover, the supernatural elements of the novel resonate with evolved intuitions about non-material, moral forces at work in the world. That is why the novel continues to engage readers worldwide. Most critics, however, have overlooked or distorted...... the psychological underpinnings of the novel and the crucial function of the supernatural elements in the meaning structure of the novel. Hence we need an evolutionary psychological perspective which builds on recent findings in the sciences of human nature to account for the novel’s meaning, effects, and continued...

    Seawater has occupied an ambiguous place in anthropological categories of "nature" and "culture." Seawater as nature appears as potentiality of form and uncontainable flux; it moves faster than culture - with culture frequently figured through land-based metaphors - even as culture seeks to channel water's (nature's) flow. Seawater as culture manifests as a medium of pleasure, sustenance, travel, disaster. I argue that, although seawater's qualities in early anthropology were portrayed impressionistically, today technical, scientific descriptions of water's form prevail. For example, processes of globalization - which may also be called "oceanization" - are often described as "currents," "flows," and "circulations." Examining sea-set ethnography, maritime anthropologies, and contemporary social theory, I propose that seawater has operated as a “theory machine” for generating insights about human cultural organization. I develop this argument with ethnography from the Sargasso Sea and in the Sea Islands. I conclude with a critique of appeals to water's form in social theory.

    The object of the issue is a wonderful museum on the Kulikovo Field designed by Sergey Gnedovsky. The unusual architecture of the new museum makes it akin to the earth’s tectonic fault caused by an intolerable tension in expectation of the battle (pp. 113-123. Oleg Yavein and Ilya Lezhava bring us back to the classic of the 20th century Mies van der Rohe and his unique dialogue with nature (pp. 162-175. Relationship between architecture and nature is a rich and limitless theme, like both of these substances. That is why the new Project Baikal issue contains, as usual, more questions than answers.

    1995-01-01

    The regulation of Natural Gas. Natural gas Regulation clarifies and consolidates the legal and institutional framework for development of the industry through six principal elements: 1) Establishment of a vision of the industry. 2) Development of regulatory objectives. 3) Determination of relationships among industry participants. 4) Clear specification of the role of PEMEX in the industry. 5) Definition of the functions of the Regulatory authority. 6) Creation of a transition regime. In parallel with the development of the substantive legal framework, the law of the Comision Reguladora de Energia (CRE) was also enacted by Congress in October 1995 to strength the institutional framework and implement the legal changes. This law defines the CRE as an agency of the Energy Ministry with technical, operational, and budgetary autonomy, and responsibility for implementing natural gas industry regulation. (Author)

    Seddelmeyer, J.

    1991-01-01

    The assessment and collection of natural resource damages from petroleum and chemical companies unfortunate enough to have injured publicly owned natural resources is perhaps the most rapidly expanding area of environmental liability. The idea of recovering for injury to publicly owned natural resources is an extension of traditional common law tort concepts under which a person who negligently injures another or his property is called upon to compensate the injured party. Normally, once liability has been established, it is a fairly straightforward matter to calculate the various elements of loss, such as the cost to repair or replace damaged property, or medical expenses, and lost income. More difficult questions, such as the amount to be awarded for pain and suffering or emotional distress, are left to the jury, although courts limit the circumstances in which the jury is permitted to award such damages

    Photonic structures appeared in nature several hundred millions years ago. In the living world, color is used for communication and this important function strongly impacts the individual chances of survival as well as the chances to reproduce. This has a statistical influence on species populations. Therefore, because they are involved in evolution, natural color-generating structures are - from some point of view - highly optimized. In this short review, a survey is presented of the development of natural photonic crystal-type structures occurring in insects, spiders, birds, fishes and other marine animals, in plants and more, from the standpoint of light-waves propagation. One-, two-, and three-dimensional structures will be reviewed with selected examples.

    Full Text Available Malaria is a human infectious disease that is caused by four species of Plasmodium. It is responsible for more than 1 million deaths per year. Natural products contain a great variety of chemical structures and have been screened for antiplasmodial activity as potential sources of new antimalarial drugs. This review highlights studies on natural products with antimalarial and antiplasmodial activity reported in the literature from January 2009 to November 2010. A total of 360 antiplasmodial natural products comprised of terpenes, including iridoids, sesquiterpenes, diterpenes, terpenoid benzoquinones, steroids, quassinoids, limonoids, curcubitacins, and lanostanes; flavonoids; alkaloids; peptides; phenylalkanoids; xanthones; naphthopyrones; polyketides, including halenaquinones, peroxides, polyacetylenes, and resorcylic acids; depsidones; benzophenones; macrolides; and miscellaneous compounds, including halogenated compounds and chromenes are listed in this review.

    Full Text Available Leather is a fibrous protein consisting of collagen in a three dimensionally crosslinked network. Chrome tanning of leather improves the appearance of leather but at the same time emits both solid and liquid chrome leather wastes. Scrap rubber recycling using untreated and neutralized leather fibrous particles in natural rubber has been studied. Vulcanization, mechanical, morphological and swelling properties of the natural rubber - scrap rubber composites containing neutralized leather have been discussed. Use of chrome leather particles has been found to improve the consumption of scrap rubber powder in natural rubber formulations. Polymer composites based on leather wastes as fillers are reported to be useful for many applications such as in construction materials, automobile interior moldings, heat and sound insulating boards, shoe soles, flooring materials and moldings with good anti-static properties, air permeability and good appearances.

    1991-01-01

    Canada's natural gas industry enjoys a quiet confidence as it looks ahead to the 1990s. In this paper, the author explains why, despite some critical uncertainties, the optimism endures. Reviewing the current conditions of supply, production, consumption, pipelines, and pipeline expansion plans, the author contends that the New World of the 1990s will belong to natural gas. The author's assessment of natural gas markets proceeds far beyond the borders of Canada. The author examines the determinants of gas prices throughout North America and he identifies the one force that promises to seize almost complete control of gas prices throughout the continent. While the analysis points out the attributes of this new pricing regime, it also names the obstacles that could prevent this emerging mechanism from assuming its anticipated position

    The components of the natural background radiation and their variations are described. Cosmic radiation is a major contributor to the external dose to the human body whilst naturally-occurring radionuclides of primordial and cosmogenic origin contribute to both the external and internal doses, with the primordial radionuclides being the major contributor in both cases. Man has continually modified the radiation dose to which he has been subjected. The two traditional methods of measuring background radiation, ionisation chamber measurements and scintillation counting, are looked at and the prospect of using thermoluminescent dosimetry is considered

    Following a short account of natural atmospheric radioactivity, radon concentrations are given as well as their variations with time obtained by means of a original apparatus developped in Brest. The radioactive equilibrium of radon and its daughters is then considered, many experiments demonstrating that equilibrium is seldom reached even for 218 Po (RaA). Finally, some characteristics of natural radioactive aerosols are studied: charge, particle size distribution (demonstrating they are fine aerosols since only 30 per cent are made of particles with radii exceeding 0,1 μm) [fr

    After having summed up the different old or new units, used in radioactivity and radioprotection, the origins of atmospheric radioactivity are reported. Next the authors deal with the air content in radon, thoron and their radioactive descendants, insisting on the variations of the radon air content and on the radioactive balance between radon and its descendants. Then a few notions concerning the natural radioactive aerosol are developed: electric charge state, granulometric distribution. The possible effects of natural atmospheric radioactivity on man are studied with a distinction between inner irradiation and outer irradiation, an average assessment is shown. Finally the important problem of radon in inhabitations is approached [fr

    Batell, Brian; McCullough, Matthew

    2015-01-01

    We study how, as a result of the scanning of supersymmetry breaking during the cosmological evolution, a relaxation mechanism can naturally determine a hierarchy between the weak scale and the masses of supersymmetric particles. Supersymmetry breaking is determined by QCD instanton effects, in an extremely minimal setup in which a single field drives the relaxation and breaks supersymmetry. Since gauginos are lighter than the other supersymmetric particles by a one-loop factor, the theory is a realisation of Split Supersymmetry free from the naturalness problem.

    Full Text Available Resumen:En este ensayo abordo los intentos, relativamente recientes, de dar una explicación de la moralidad como adaptación por selección natural. Mi exposición tiene una introducción y cuatro partes: en la primera explico en qué consiste la paradoja del altruismo biológico. En la segunda expongo la solución que apela a la selección de grupos, recientemente resurgida; la solución que presuntamente aplicó Charles Darwin cuando formuló sus reflexiones biológicas sobre la moralidad humana. En la tercera expongo la solución sociobiológica, que opta por negar que la selección natural pueda explicar directamente la moralidad humana. La moralidad se presenta más bien como opuesta a la naturaleza diseñada por selección natural. En la cuarta parte desarrollo brevemente una explicación de la moralidad como adaptación que beneficia a los individuos. No opone la moralidad a la naturaleza, ni apela a la selección de grupos. Se sirve de un mecanismo de selección que opera a través de preferencias en la interacción social.Abstract:In this essay, I address recent attempts to account for morality as an adaptation due to natural selection. After a brief introduction, my exposition has four sections. I first explain the paradox of biological altruism. Second, I explain the solution to the paradox in terms of group selection. This solution was presumably applied by Darwin himself as he discussed human morality, and it has experienced a recent revival, though it remains suspicious to most biologists. In the third section I offer a socio-biological solution that opts for denying that morality can be explained by any form of natural selection. Morality is opposed to human nature as designed by natural selection. In the fourth, I argue for an explanation in terms of individual selection. It does not oppose morality to nature, and does not need the workings of group selection; rather, it operates through the agents’ psychological preferences

    This seminar describes a process and methodology that uses structured natural language to enable the construction of precise information requirements directly from users, experts, and managers. The main focus of this natural language approach is to create the precise information requirements and to do it in such a way that the business and technical experts are fully accountable for the results. These requirements can then be implemented using appropriate tools and technology. This requirement set is also a universal learning tool because it has all of the knowledge that is needed to understand a particular process (e.g., expense vouchers, project management, budget reviews, tax, laws, machine function).

    This paper reports on the natural gas outlook for Venezuela. First of all, it is very important to remember that in the last few years we have had frequent and unforeseen changes in the energy, ecological, geopolitical and economical fields which explain why all the projections of demand and prices for hydrocarbons and their products have failed to predict what later would happen in the market. Natural gas, with its recognized advantages over other traditional competitors such as oil, coal and nuclear energy, is identified as the component that is acquiring more weight in the energy equation, with a strengthening projection, not only as a resource that covers demand but as a key element in the international energy business. In fact, natural gas satisfies 21% of overall worldwide energy consumption, with an annual increase of 2.7% over the last few years, which is higher than the global energy growth of other fossil fuels. This tendency, which dates from the beginning of the 1980's, will continue with a possibility of increasing over the coming years. Under a foreseeable scenario, it is estimated that worldwide use of natural gas will increase 40% over the next 10 years and 75% on a longer term. Specifically for liquid methane (LNG), use should increase 60% during this last decade. The LPG increase should be moderate due to the limited demand until 1995 and to the stable trends that will continue its use until the end of this century

    The mission of the U.S. Geological Survey (USGS) in natural hazards is to develop and apply hazard science to help protect the safety, security, and economic well-being of the Nation. The costs and consequences of natural hazards can be enormous, and each year more people and infrastructure are at risk. USGS scientific research—founded on detailed observations and improved understanding of the responsible physical processes—can help to understand and reduce natural hazard risks and to make and effectively communicate reliable statements about hazard characteristics, such as frequency, magnitude, extent, onset, consequences, and where possible, the time of future events.To accomplish its broad hazard mission, the USGS maintains an expert workforce of scientists and technicians in the earth sciences, hydrology, biology, geography, social and behavioral sciences, and other fields, and engages cooperatively with numerous agencies, research institutions, and organizations in the public and private sectors, across the Nation and around the world. The scientific expertise required to accomplish the USGS mission in natural hazards includes a wide range of disciplines that this report refers to, in aggregate, as hazard science.In October 2010, the Natural Hazards Science Strategy Planning Team (H–SSPT) was charged with developing a long-term (10-year) Science Strategy for the USGS mission in natural hazards. This report fulfills that charge, with a document hereinafter referred to as the Strategy, to provide scientific observations, analyses, and research that are critical for the Nation to become more resilient to natural hazards. Science provides the information that decisionmakers need to determine whether risk management activities are worthwhile. Moreover, as the agency with the perspective of geologic time, the USGS is uniquely positioned to extend the collective experience of society to prepare for events outside current memory. The USGS has critical statutory

    The rise in solar ultraviolet radiation on the earth's surface has led to a depletion of stratospheric ozone over recent decades, thus accelerating the need to protect human skin against the harmful effects of UV radiation such as erythema, edema, hyperpigmentation, photoaging, and skin cancer. There are many different ways to protect skin against UV radiation's harmful effects. The most popular way to reduce the amount of UV radiation penetrating the skin is topical application of sunscreen products that contain UV absorbing or reflecting active molecules. Based on their protection mechanism, the active molecules in sunscreens are broadly divided into inorganic and organic agents. Inorganic sunscreens reflect and scatter UV and visible radiation, while organic sunscreens absorb UV radiation and then re-emit energy as heat or light. These synthetic molecules have limited concentration according to regulation concern. Several natural compounds with UV absorption property have been used to substitute for or to reduce the quantity of synthetic sunscreen agents. In addition to UV absorption property, most natural compounds were found to act as antioxidants, anti-inflammatory, and immunomodulatory agents, which provide further protection against the damaging effects of UV radiation exposure. Compounds derived from natural sources have gained considerable attention for use in sunscreen products and have bolstered the market trend toward natural cosmetics. This adds to the importance of there being a wide selection of active molecules in sunscreen formulations. This paper summarizes a number of natural products derived from propolis, plants, algae, and lichens that have shown potential photoprotection properties against UV radiation exposure-induced skin damage. © 2015 Wiley Periodicals, Inc.

  1. Design, science and naturalism

    Science.gov (United States)

    Deming, David

    2008-09-01

    The Design Argument is the proposition that the presence of order in the universe is evidence for the existence of God. The Argument dates at least to the presocratic Greek philosophers, and is largely based on analogical reasoning. Following the appearance of Aquinas' Summa Theologica in the 13th century, the Christian Church in Europe embraced a Natural Theology based on observation and reason that allowed it to dominate the entire world of knowledge. Science in turn advanced itself by demonstrating that it could be of service to theology, the recognized queen of the sciences. During the heyday of British Natural Theology in the 17th and 18th centuries, the watchmaker, shipbuilder, and architect analogies were invoked reflexively by philosophers, theologians, and scientists. The Design Argument was not systematically and analytically criticized until David Hume wrote Dialogues on Natural Religion in the 1750s. After Darwin published Origin of Species in 1859, Design withered on the vine. But in recent years, the Argument has been resurrected under the appellation "intelligent design," and been the subject of political and legal controversy in the United States. Design advocates have argued that intelligent design can be formulated as a scientific hypothesis, that new scientific discoveries validate a design inference, and that naturalism must be removed as a methodological requirement in science. If science is defined by a model of concentric epistemological zonation, design cannot be construed as a scientific hypothesis because it is inconsistent with the core aspects of scientific methodology: naturalism, uniformity, induction, and efficient causation. An analytical examination of claims by design advocates finds no evidence of any type to support either scientific or philosophical claims that design can be unambiguously inferred from nature. The apparent irreducible complexity of biological mechanisms may be explained by exaptation or scaffolding. The argument

    In recent years, green energy has undergone a lot of development and has been the subject of many applications. Many research studies have focused on illumination with sunlight as a means of saving energy and creating healthy lighting. Natural light illumination systems have collecting, transmitting, and lighting elements. Today, most daylight collectors use dynamic concentrators; these include Sun tracking systems. However, this design is too expensive to be cost effective. To create a low-cost collector that can be easily installed on a large building, we have designed a static concentrator, which is prismatic and cascadable, to collect sunlight for indoor illumination. The transmission component uses a large number of optical fibers. Because optical fibers are expensive, this means that most of the cost for the system will be related to transmission. In this paper, we also use a prismatic structure to design an optical coupler for coupling n to 1. With the n-to-1 coupler, the number of optical fibers necessary can be greatly reduced. Although this new natural light illumination system can effectively guide collected sunlight and send it to the basement or to other indoor places for healthy lighting, previously there has been no way to manage the collected sunlight when lighting was not desired. To solve this problem, we have designed an optical switch and a beam splitter to control and separate the transmitted light. When replacing traditional sources, the lighting should have similar characteristics, such as intensity distribution and geometric parameters, to those of traditional artificial sources. We have designed, simulated, and optimized an illumination lightpipe with a dot pattern to redistribute the collected sunlight from the natural light illumination system such that it equals the qualities of a traditional lighting system. We also provide an active lighting module that provides lighting from the natural light illumination system or LED auxiliary

    We construct two simple effective field theory versions of Hybrid Natural Inflation (HNI) that illustrate the range of its phenomenological implications. The resulting inflationary sector potential, V = Δ4(1 + acos( ϕ/f)), arises naturally, with the inflaton field a pseudo-Nambu-Goldstone boson. The end of inflation is triggered by a waterfall field and the conditions for this to happen are determined. Also of interest is the fact that the slow-roll parameter ɛ (and hence the tensor r) is a non-monotonic function of the field with a maximum where observables take universal values that determines the maximum possible tensor to scalar ratio r. In one of the models the inflationary scale can be as low as the electroweak scale. We explore in detail the associated HNI phenomenology, taking account of the constraints from Black Hole production, and perform a detailed fit to the Planck 2015 temperature and polarisation data.

    A Natural Analogue Working Group was established by the Commission of the European Communities in 1985. The purpose of this group is to bring together modellers with earth scientists and others, so that maximum benefit can be obtained from natural analogue studies with a view to safe geological disposal of radioactive waste. The first meeting of this group was held in Brussels from November 5 to 7, 1985. The discussions mainly concerned the identification of the modellers' needs and of the earth scientists' capacity to provide for them. Following the debates, a written statement was produced by the Group; this document forms the core of the present Report. Notes and outlines of many of the presentations made are grouped in four appendixes. The valuable contribution of all those involved in the meeting is gratefully acknowledged

    In recent years, there has been a growing tendency to avoid the use of artificial colorants and additives in food products, especially after some studies linked their consumption with behavioural changes in children. However, the incorporation of colorants from natural origin remains a challenge...... for food technologists, as these are typically less vivid and less stable than their synthetic alternatives. Regarding blue colorants, phycocyanins from cyanobacteria are currently in the spotlight as promising new natural blue colorants. Phycocyanins are proteins which blue colour results from...... the presence of the chromophore phycocyanobilin (PCB), a covalently attached linear tetrapyrrole. The applications of phycocyanins as food colorants are however limited, as they show poor stability in certain conditions of pH, light and temperature. Cleavage of PCB from the protein followed by careful product...

  8. Epidemics after Natural Disasters

    2007-01-01

    The relationship between natural disasters and communicable diseases is frequently misconstrued. The risk for outbreaks is often presumed to be very high in the chaos that follows natural disasters, a fear likely derived from a perceived association between dead bodies and epidemics. However, the risk factors for outbreaks after disasters are associated primarily with population displacement. The availability of safe water and sanitation facilities, the degree of crowding, the underlying health status of the population, and the availability of healthcare services all interact within the context of the local disease ecology to influence the risk for communicable diseases and death in the affected population. We outline the risk factors for outbreaks after a disaster, review the communicable diseases likely to be important, and establish priorities to address communicable diseases in disaster settings.

    2014-03-01

    Full Text Available The purpose of this paper is to reconstruct Hilary Kornblith’s (2002 argument for excluding conceptual analysis from epistemological inquiry, and then provide three objections to it. More specifically, Kornblith argues that epistemological properties such as ‘knowledge’ reduce to natural kinds (with a constitutive essence which can only be discovered and investigated using the a posteriori methods of the natural sciences. Thus, he continues, conceptual analysis can’t properly illuminate the target domain. The three objections to Kornblith’s argument which I present are as follows: (i Multiple Realizeability, (ii Psychological Explanation, (iii Starting Points. On strength of these objections, I conclude that Kornblith’s brand of a posteriori epistemology both eliminates our ability to make epistemic evaluations in general, and also implies a strong form of scepticism.

    1993-01-01

    The natural gas industry and market prospects in Canada are reviewed from a producer's point of view. In the first eight months of 1993, $2.3 billion in new equity was raised for natural gas exploration and production, compared to $900 million in 1991 and $1.2 billion in 1992. The number of wells drilled in the western Canada basin is expected to reach 8,000-9,000 in 1993, up from 5,600 in 1992, and Canadian producers' share of the North American natural gas market will probably reach 20% in 1993, up from 13% in 1986. Potential and proved gas supply in North America is ca 750 trillion ft 3 , of which ca 30% is in Canada. Factors affecting gas producers in Canada are the deregulated nature of the market, low costs for finding gas (finding costs in the western Canada basin are the lowest of any basin in North America), and the coming into balance of gas supply and demand. The former gas surplus has been reduced by expanding markets and by low prices which reduced the incentive to find new reserves. This surplus is largely gone, and prices have started rising although they are still lower than the pre-deregulation prices. Progress is continuing toward an integrated North American gas market in which a number of market hubs allow easy gas trading between producers and consumers. Commodity exchanges for hedging gas prices are beginning operation and electronic trading of gas contracts and pipeline capacity will also become a reality. 4 figs

    The first 1 fb{sup -1} of LHC searches have set impressive limits on new colored particles decaying to missing energy. We address the implication of these searches for naturalness in supersymmetry (SUSY). General bottom-up considerations of natural electroweak symmetry breaking show that higgsinos, stops, and the gluino should not be too far above the weak scale. The rest of the spectrum, including the squarks of the first two generations, can be heavier and beyond the current LHC reach. We have used collider simulations to determine the limits that all of the 1 fb{sup -1} searches pose on higgsinos, stops, and the gluino. We find that stops and the left-handed sbottom are starting to be constrained and must be heavier than about 200-300 GeV when decaying to higgsinos. The gluino must be heavier than about 600-800 GeV when it decays to stops and sbottoms. While these findings point toward scenarios with a lighter third generation split from the other squarks, we do find that moderately-tuned regions remain, where the gluino is just above 1 TeV and all the squarks are degenerate and light. Among all the searches, jets plus missing energy and same-sign dileptons often provide the most powerful probes of natural SUSY. Overall, our results indicate that natural SUSY has survived the first 1 fb{sup -1} of data. The LHC is now on the brink of exploring the most interesting region of SUSY parameter space. (orig.)

  20. Microflyers: inspiration from nature

    Science.gov (United States)

    Sirohi, Jayant

    2013-04-01

    Over the past decade, there has been considerable interest in miniaturizing aircraft to create a class of extremely small, robotic vehicles with a gross mass on the order of tens of grams and a dimension on the order of tens of centimeters. These are collectively refered to as micro aerial vehicles (MAVs) or microflyers. Because the size of microflyers is on the same order as that of small birds and large insects, engineers are turning to nature for inspiration. Bioinspired concepts make use of structural or aerodynamic mechanisms that are observed in insects and birds, such as elastic energy storage and unsteady aerodynamics. Biomimetic concepts attempt to replicate the form and function of natural flyers, such as flapping-wing propulsion and external appearance. This paper reviews recent developments in the area of man-made microflyers. The design space for microflyers will be described, along with fundamental physical limits to miniaturization. Key aerodynamic phenomena at the scale of microflyers will be highlighted. Because the focus is on bioinspiration and biomimetics, scaled-down versions of conventional aircraft, such as fixed wing micro air vehicles and microhelicopters will not be addressed. A few representative bioinspired and biomimetic microflyer concepts developed by researchers will be described in detail. Finally, some of the sensing mechanisms used by natural flyers that are being implemented in man-made microflyers will be discussed.

    Substantial increases in demand for Canadian petroleum and natural gas in both domestic and export markets resulted in another good year throughout the main sectors of the industry. In February, production averaged 850,000 bpd, or about 8% more than 1963 output of crude oil and natural gas liquids. Construction began on the first full scale plant for the extraction of oil from the Athabasca bituminous sands. In 1964, exploratory and development drilling in western Canada increased 10% from the previous year. A total of 15.5 million ft was drilled, the largest since the record drilling year of 1956. The main oil field development areas in Alberta were the House Mountain, Deer Mountain and Goose River Fields, and the Bantry-Taber heavy oil region in southeastern Alberta. Oil reserves were increased substantially by waterflood pressure maintenance projects in many of the older oil fields. The largest oil accumulation discovered in 1964 was the Syvia-Honda Field in the Devonian Gilwood sandstone in N.-central Alberta. Two graphs illustrate the crude petroleum in Canada in millions of barrels from 1940 to 1964, and natural gas in Canada in billions of cu ft from 1950 to 1964. The outlook for the industry in 1965 is good.

    The purpose of this report is to summarize the scientific work that was performed to evaluate and assess the occurrence and economic potential of natural resources within the geologic setting of the Yucca Mountain area. The extent of the regional areas of investigation for each commodity differs and those areas are described in more detail in the major subsections of this report. Natural resource assessments have focused on an area defined as the ''conceptual controlled area'' because of the requirements contained in the U.S. Nuclear Regulatory Commission Regulation, 10 CFR Part 60, to define long-term boundaries for potential radionuclide releases. New requirements (proposed 10 CFR Part 63 [Dyer 1999]) have obviated the need for defining such an area. However, for the purposes of this report, the area being discussed, in most cases, is the previously defined ''conceptual controlled area'', now renamed the ''natural resources site study area'' for this report (shown on Figure 1). Resource potential can be difficult to assess because it is dependent upon many factors, including economics (demand, supply, cost), the potential discovery of new uses for resources, or the potential discovery of synthetics to replace natural resource use. The evaluations summarized are based on present-day use and economic potential of the resources. The objective of this report is to summarize the existing reports and information for the Yucca Mountain area on: (1) Metallic mineral and mined energy resources (such as gold, silver, etc., including uranium); (2) Industrial rocks and minerals (such as sand, gravel, building stone, etc.); (3) Hydrocarbons (including oil, natural gas, tar sands, oil shales, and coal); and (4) Geothermal resources. Groundwater is present at the Yucca Mountain site at depths ranging from 500 to 750 m (about 1,600 to 2,500 ft) below the ground surface. Groundwater resources are not discussed in this report, but are planned to be included in the hydrology

    Real life by definition combines heritability (e.g., the legacy of exposures) and experience (e.g. stress during sensitive or ‘critical’ periods), but how to study or even model this interaction has proven difficult. The hoary concept of evaluating traits according to nature vs. nurture continues to persist despite repeated demonstrations that it retards, rather than advances, our understanding of biological processes. Behavioral genetics has proven the obvious, that genes influences behavior and, vice versa, that behavior influences genes. The concept of Genes X Environment (G X E) and its modern variants was viewed as an improvement on nature-nurture but has proven that, except in rare instances, it is not possible to fractionate phenotypes into these constituent elements. The entanglement inherent in terms such as nature-nurture or GXE is a Gordian knot that cannot be dissected or even split. Given that the world today is not what it was less than a century ago, yet the arbitrator (differential survival and reproduction) has stayed constant, de novo principles and practices are needed to better predict what the future holds. Put simply, the transformation that is now occurring within and between individuals as a product of global endocrine disruption is quite independent of what has been regarded as evolution by selection. This new perspective should focus on how epigenetic modifications might revise approaches to understand how the phenotype and, in particular its components, is shaped. In this review we summarize the literature in this developing area, focusing on our research on the fungicide vinclozolin. PMID:25102229

  7. Why Nature Chose Selenium.

    2016-04-15

    The authors were asked by the Editors of ACS Chemical Biology to write an article titled "Why Nature Chose Selenium" for the occasion of the upcoming bicentennial of the discovery of selenium by the Swedish chemist Jöns Jacob Berzelius in 1817 and styled after the famous work of Frank Westheimer on the biological chemistry of phosphate [Westheimer, F. H. (1987) Why Nature Chose Phosphates, Science 235, 1173-1178]. This work gives a history of the important discoveries of the biological processes that selenium participates in, and a point-by-point comparison of the chemistry of selenium with the atom it replaces in biology, sulfur. This analysis shows that redox chemistry is the largest chemical difference between the two chalcogens. This difference is very large for both one-electron and two-electron redox reactions. Much of this difference is due to the inability of selenium to form π bonds of all types. The outer valence electrons of selenium are also more loosely held than those of sulfur. As a result, selenium is a better nucleophile and will react with reactive oxygen species faster than sulfur, but the resulting lack of π-bond character in the Se-O bond means that the Se-oxide can be much more readily reduced in comparison to S-oxides. The combination of these properties means that replacement of sulfur with selenium in nature results in a selenium-containing biomolecule that resists permanent oxidation. Multiple examples of this gain of function behavior from the literature are discussed.

    The purpose of this report is to present analogue studies and literature reviews designed to provide qualitative and quantitative information to test and provide added confidence in process models abstracted for performance assessment (PA) and model predictions pertinent to PA. This report provides updates to studies presented in the Yucca Mountain Site Description (CRWMS M and O 2000 [151945], Section 13) and new examples gleaned from the literature along with results of quantitative studies conducted specifically for the Yucca Mountain Project (YMP). The intent of the natural analogue studies was to collect corroborative evidence from analogues to demonstrate additional understanding of processes expected to occur during postclosure at a potential Yucca Mountain repository. The report focuses on key processes by providing observations and analyses of natural and anthropogenic (human-induced) systems to improve understanding and confidence in the operation of these processes under conditions similar to those that could occur in a nuclear waste repository. The process models include those that represent both engineered and natural barrier processes. A second purpose of this report is to document the various applications of natural analogues to geologic repository programs, focusing primarily on the way analogues have been used by the YMP. This report is limited to providing support for PA in a confirmatory manner and to providing corroborative inputs for process modeling activities. Section 1.7 discusses additional limitations of this report. Key topics for this report are analogues to emplacement-drift degradation, waste-form degradation, waste-package degradation, degradation of other materials proposed for the engineered barrier, seepage into drifts, radionuclide flow and transport in the unsaturated zone (UZ), analogues to coupled thermal-hydrologic-mechanical-chemical processes, saturated-zone (SZ) transport, impact of radionuclide release on the biosphere

    Thermoluminescence (TL) as well as absorption and EPR spectra of x-irradiated natural calcites have been obtained. Irradiation produces UV absorption bands and a decrease of the Mn 2+ EPR spectrum. A correlation of each TL peak with the bleaching steps of UV absorption bands and the recovering in intensity of the Mn 2+ EPR spectrum has been found. These experimental results support a new model for the radiation damage and thermoluminescence process in calcites. The main point in this model is that holes become trapped at impurities, and the electrons are trapped at dislocations in the form of CO 3 3- . (author)

    Western Australia has 80% of Australia's natural gas resources. These are currently exploited to supply the Western Australian market and LNG to Japan. Growth in the market is dependent on limited prospects for power generation and mineral resource processing. Future exploitation of gas resources will require new export LNG markets and/or the installations of a transcontinental pipeline to eastern Australia. The transcontinental option should only be considered after other options for energy supply in eastern Australia are eliminated. Competition to meet market growth in North-east Asia will be considerable and Australia lacks the policies to underpin future LNG capacity. (author)

    Although the amounts are small, man is exposed on a daily basis to alpha, beta, and gamma radiation emitted by radioactive elements present in the earth's crust. The natural radioactive elements are measurable, either by physicochemical means or by radiometric methods and can be the cause of external or internal exposure in man. Also of importance is cosmic radiation. Of galactic or solar origin, primary cosmic rays cause external radiation exposure. The majority of these particles disintegrate rapidly. They reach the ground at a mean rate of the order of one particle per square centimeter per minute

    Full Text Available Objective: To establish the influence of clinical status at diagnosis and of gender on progression of HIV/AIDS determined by clinical-biological factors in patients from Cordoba City (Argentina from 1995 to 2005. 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.

    Mosque of Cordoba. The requirement of hypothetical auxiliary resources, such as wood props for the fixation of the capitals and tightening structures will also be considered. This methodology should be understood as a progressive path with a knowledge gradient through a graphical-numerical study that involves the use of four programs: Geogebra, Autocad + Excel, Maple and Sap2000. In this way, the same problem of the thrust line falling within the boundaries of the archery is solved in various ways to understand graphic statics from different perspectives. Moreover, creating a personal optimization model sheet will be taught as a way of accelerating and “systematizing” the calculation. The study will be followed by more complex analysis using symbolic calculation programs. As a result of the learning process described, the limitation and difficulties of each way of approaching the stability problem of the archery will be understood. Not only that, but also students will take advantage of the freedom offered when proceeding to the limit analysis suited to their own interests, always having graphical support.

    The reform of the EEG in Germany, a positive global development in natural gas, the decline in oil prices, questions about the security of supply in Europe, and not least the effect of the decision by E.on at the end of 2014 have moved the gas industry. Gas has the lowest CO{sub 2} emissions of fossil fuels. Flexibility, storability, useful for networks and the diversity in the application make it an ideal partner for renewable energy. However, these complementary properties are valued at wind and photovoltaics internationally and nationally different. The situation in the gas power plants remains tense. LNG - liquefied natural gas - is on the rise.

    CERN is nestled within a verdant natural environment which, thanks to a conservation-oriented policy, is characterized by a remarkable biodiversity. The continued protection of that diversity calls for thoughtful, carefully planned measures.   CERN’s site is an extensive one: its 650 hectares include 210 hectares of buildings, roadways and parking lots, 100 hectares of fenced-off green area, and 340 hectares of non-fenced land, a patchwork of fields, woods and pasture. This land teems with a great variety of plants and animals, including some rare and unexpected species. In 2009 CERN received a certificate from the Swiss foundation Nature & économie for the Meyrin site, and the award was renewed in 2012 for three more years. “The green spaces inside the fenced area are tended by six ISS gardeners, whose duties also include keeping the sidewalks and footpaths clear of snow in winter.

  1. Natural Circulation with Boiling

    Mathisen, R P

    1967-09-15

    A number of parameters with dominant influence on the power level at hydrodynamic instability in natural circulation, two-phase flow, have been studied experimentally. The geometrical dependent quantities were: the system driving head, the boiling channel and riser dimensions, the single-phase as well as the two phase flow restrictions. The parameters influencing the liquid properties were the system pressure and the test section inlet subcooling. The threshold of instability was determined by plotting the noise characteristics in the mass flow records against power. The flow responses to artificially obtained power disturbances at instability conditions were also measured in order to study the nature of hydrodynamic instability. The results presented give a review over relatively wide ranges of the main parameters, mainly concerning the coolant performance in both single and parallel boiling channel flow. With regard to the power limits the experimental results verified that the single boiling channel performance was intimately related to that of the parallel channels. In the latter case the additional inter-channel factors with attenuating effects were studied. Some optimum values of the parameters were observed.

Populations can be catogorized into skin types I-VI and the minimal erythema dose (MED) in each skin type measured in Joules/cm2 was compared to give a relative suntan photoprotection factor or SPF compared with type I (1.0) so that type II had an SPF of 1.67, type III SPF of 2.5, type IV V had an SPF of nearly 4, whereas the darker Negroid skin (type VI) had an SPF of 9.68, or nearly 10 times that of type I. In addition, various studies were performed to determine the natural protection factor after natural sunlight (3 1/2 mo of summer sun). In 21 subjects the mean SPF was 2.33 when compared to the MED on unexposed skin on the buttocks. Five subjects who had received a mean total dose of 3.49 J/cm2 of UVB within a 4-week period had a mean SPF of 8.01 and 5 subjects who had received a mean total dose of 20 J/cm2 of UVA with PUVA therapy within 2 weeks had a mean SPF of 2.7.

    The discovery of a 125.5 GeV Higgs with standard model-like couplings and naturalness considerations motivate gauge extensions of the MSSM. We analyse two variants of such an extension and carry out a phenomenological study of regions of the parameter space statisfying current direct and indirect constraints, employing state-of-the-art two-loop RGE evolution and GMSB boundary conditions. We find that due to the appearance of non-decoupled D-terms it is possible to obtain a 125.5 GeV Higgs with stops below 2 TeV, while the uncolored sparticles could still lie within reach of the LHC. We compare the contributions of the stop sector and the non-decoupled D-terms to the Higgs mass, and study their effect on the Higgs couplings. We further investigate the nature of the next-to lightest supersymmetric particle, in light of the GMSB motivated searches currently being pursued by ATLAS and CMS.

    It is well documented that diets rich in fruits and vegetables can reduce the risk of most common cancers, and that some food items from this class may be protective against heart disease. Several explanations have been offered, one of which relates to the natural presence of potent antioxidants in plant products. Destructive oxidation of lipids, proteins, DNA, and other important biomolecules, often involving radical chain reactions, affect vital cellular structures and their normal functions. Such processes are involved in the development of cancer as well as heart disease, and it seems logical to assume that antioxidants might be preventive. Large human trials with natural antioxidants have not provided a uniform support, however, for the hypothesis that antioxidation per se may prevent cancer or coronary heart disease (CHD). One reason is that other effects, unrelated to antioxidation, may compromise their preventive effects. Another reason may be that many potent antioxidants can also act as pro-oxidants under certain conditions. The interpretation of animal trials is likewise often compromised by the fact that most antioxidants have other physiological effects which might very well explain their protective action or lead to toxic side-effects.

    Full Text Available By way of introducing this special issue of Museum and Society, ‘Constructing nature behind glass’, this paper first surveys the literature devoted to analyses of natural history objects and collections. Such work is to be found in interesting places – not only in museum studies, history of science, and professional museum literature, but also in visual studies, anthropology and cultural geography. After exploiting this writing for different perspectives on the cultural and practical construction of museum nature, this paper moves on to consider one popular topic, taxidermy. The ambiguous nature of taxidermic mounts, or ‘remnant models’, leads to a discussion of the relative status of specimen and artefact. I identify four configurations of their relationship: museum nature as opposed to material culture; museum nature as material culture; museum nature and material culture sharing parallel processes; and finally, museum nature and material culture entangled. All offer perspectives on the construction of nature and culture behind glass.

Important topics are visited once a year, whether or not something specially exciting happened in the last 12 months. Add to this list Seminars in Cell and Developmental Biology, the FASEB journal and the countless minireviews in 'real' journals, and you begin to wonder how anyone finds any time for doing experiments, or indeed reading the primary literature. So, into this already crowded field arrive three important newcomers: Nature Reviews in Molecular Cell Biology, Genetics, and Neurosciences, of which the first two will probably interest readers of Journal of Cell Science the most. Backed by the name and money of Nature and edited by experienced Nature staff, it is hard to see how these publications can possibly do other than succeed with writers and readers alike. What's inside the first issue? The cover of Nature Reviews in Molecular Cell Biology presents a 3-colour montage of a blue cell nucleus surrounded by splotches of green GPI-anchored GFP overlaid by orange actin stress fibres that seem to come from somewhere else. This image trails a comprehensive review from Kai Simons and Derek Toomre about Lipid Rafts. There are another five major review articles: calcium puffs and sparks, rings around DNA, HIV inhibitors, kinesin and the circadian clock provide a rich and varied mix of topics from authors who know what they're talking about. Surrounding this core is an entertaining mixture of 'highlights' at the front: news and views about

  9. Natural gas : nirvana

    International Nuclear Information System (INIS)

    Stonehouse, D.

    2001-01-01

    Despite completing 8,900 gas wells in year 2000, the deliverability of natural gas out of the Western Canadian Sedimentary Basin (WCSB) was stagnant which has left many analysts wondering whether the basin has reached its limit. It also leaves many wondering if gas producers will be able to meet the strong demand for natural gas in the future. Nearly all new electrical generation being built in the U.S. is gas-based due to strict new environmental standards limiting the growth in hydro and coal-powered generation. Any future coal plants will use gasification technology and combined cycle turbines. Combined cycle turbines developed by Boeing and Lockheed are more efficient than combustion turbines, making gas more competitive with fuel alternatives. The lack of growth in natural gas supply has left storage levels near record lows. Demand is expected to increase in 2001 by 3.2 per cent to 23 trillion cubic feet in the U.S. Longer term, major new reserves must be brought on stream to meet this demand. It was noted that the easy discoveries within the WCSB have been made. The new plays are smaller, more technically complex and expensive which suggests that more investment is needed in training geologists, geophysicists and petroleum engineers to find new reserves. The Canadian Energy Research Institute agrees that there is enough gas in Alberta and British Columbia to meet current demands but efforts must shift towards drilling in the foothills front and northwest regions of Alberta to increase deliverability. Brief notes on several gas finds by various oil and gas companies in the area were presented. The article also discussed the huge untapped potential of northern reserves. Analysts have noted 44 Tcf of proven reserve, with a potential of 165 Tcf. In addition, new pipelines from the Alaskan North Slope and the Mackenzie Delta could transport nearly 2 Tcf annually to market. Wells drilled by Chevron and Paramount at Fort Liard in 1999 initially flowed at rates up to

    Full Text Available Se probaron alimentos artificiales y naturales con larva de camarón (Litopenaeus vannamei cultivados en diferentes recipientes. Estos fueron ocho frascos cónicos con 15L, ocho acuarios con 50L y como grupo control, seis tanques de fibra de vidrio con 1500L; todos con agua marina fresca y filtrada. La densidad inicial en todos los recipientes fue de 70 nauplios/L. Aquellos en frascos y acuarios recibieron ya sea dieta natural o artificial. El grupo control fue cultivado con dieta natural en los tanques grandes que utilizan los laboratorios para la producción masiva de postlarvas. El principal producto de excreción de larva de camarón es el ión amonio, que es tóxico cuando está presente en concentraciones elevadas. Se determinó diariamente con el método colorimétrico del indofenol. Los resultados muestran diferencias en la concentración del ión amonio y en la sobrevivencia de larvas entre las diferentes dietas y también entre los diferentes recipientes. En aquellos con volúmenes pequeños comparados con los grandes, se presentó mayor concentración de amonio (500 a 750µg/L, en aquellos con dietas naturales, debido a que este ión sirve de fertilizante a las algas adicionadas, necesitando efectuar recambios diarios de agua posteriores al noveno día de cultivo para mantener este ión a una concentración subletal. Se obtuvo una baja cosecha de postlarvas (menor a 15% con el alimento artificial larvario, debido a la presencia de protozoarios, alimentándose con el producto comercial precipitado en el fondo de los frascos o acuarios. Los acuarios con larvas alimentadas con dieta natural también mostraron concentraciones subletales de amonio al noveno día; sin embargo, la sobrevivencia fue cuatro veces mayor que con dietas artificiales. Los tanques control con dietas naturales presentaron tasas de sobrevivencia (70 ± 5% similares a la reportada por otros laboratorios.

    D'Amico, R

    1995-10-01

    In The Nature of Disease, Lawrie Reznek argues that disease is not a natural kind term. I raise objections to Reznek's two central arguments for establishing that disease is not a natural kind. In criticizing his a priori, conceptual argument against naturalism, I argue that his conclusion rests on a weaker argument that appeals to the empirical diversity in the symptoms and manifestations of disease. I also raise questions about the account of natural kinds which Reznek utilizes and his point that conventions for classification are excluded by there being natural kinds.

  13. Liquefied Natural Gas Transfer

    Science.gov (United States)

    1980-01-01

    Chicago Bridge & Iron Company's tanks and associated piping are parts of system for transferring liquefied natural gas from ship to shore and storing it. LNG is a "cryogenic" fluid meaning that it must be contained and transferred at very low temperatures, about 260 degrees below Fahrenheit. Before the LNG can be pumped from the ship to the storage tanks, the two foot diameter transfer pipes must be cooled in order to avoid difficulties associated with sharp differences of temperature between the supercold fluid and relatively warm pipes. Cooldown is accomplished by sending small steady flow of the cryogenic substance through the pipeline; the rate of flow must be precisely controlled or the transfer line will be subjected to undesirable thermal stress.

    Ruppel, Carolyn D.

    2018-01-17

    Gas hydrate is a naturally occurring, ice-like substance that forms when water and gas combine under high pressure and at moderate temperatures. Methane is the most common gas present in gas hydrate, although other gases may also be included in hydrate structures, particularly in areas close to conventional oil and gas reservoirs. Gas hydrate is widespread in ocean-bottom sediments at water depths greater than 300–500 meters (m; 984–1,640 feet [ft]) and is also present in areas with permanently frozen ground (permafrost). Several countries are evaluating gas hydrate as a possible energy resource in deepwater or permafrost settings. Gas hydrate is also under investigation to determine how environmental change may affect these deposits.

  16. OPEC and natural gas

    Samsam Bakhtiari, A.M.; Shahbudaghlou, F.

    1998-01-01

    This paper reviews the involvement of OPEC Member Countries in the natural gas industry in the past, present and future. It notes a tenfold increase in marketed production and a fourfold rise in re-injection since 1970. Collectively, Members now hold 41 per cent of the world's proven gas reserves and account for 20 per cent of exports. Individually, four of these countries hold position 2-5 in the world gas reserve rankings. Within OPEC, however, there remains an emphasis of oil over gas, not least because of oil's favourable position with regard to revenue-generation and profitability. As global demand continues on its upward growth curve in a more environmentally aware world, OPEC's gas horizons will widen. OPEC's strong reserve base will give its Members an undeniable role to play on the future global gas stage. However, these countries will give priority to domestic usage, particularly re-injection schemes

    The content of 40K natural radionuclide in bananas (Musa sapientum) from the Vale do Ribeira region, São Paulo, Brazil, has been measured. We have collected several samples of bananas prata and nanica, its peels, leaves, and also different soils where the banana tree was planted, such as soil with a standard amount of fertilizer, the fertilizer itself and also soil without fertilizer for comparison. We have used the gamma-ray spectroscopy technique with a NaI(T1) crystal inside a 12 cm thick lead shield to detect the gamma-radiation. The results indicate that only part of the available potassium is absorbed by the plant, which is mainly concentrated in the banana peel.

    Full Text Available This article presents a visual artist’s point of view about art. This view confronts the Eurocentric traditional cannon with some ignored, but valuable traditions, thus proposing a contra-canon. These ideas are examined on the light of a variety of sources, including prehistoric, pre-Columbian, and 20th century art expressions, in a variety of media, from sculpture to literature. Recent art expressions are characterized by their incorporation of minority values and perspectives that challenge “universal” views. Using samples of works from Latino and African American artists, the author shows that, even today, art is a means to know the world and its people, to exhibit personal life, to create personal symbolism, and to show one’s identity or the search for it. Like the human nature it represents, art has multiple faces.

    Full Text Available Sometimes a player will stray from the path described by a game, moving into new spaces, developing new possible modes of interaction, and often discovering the rougher edges of the game world, where physics models break down, textures become incongruous, and the pieces don’t quite fit together. Gameplay that seeks out these spaces and these phenomena, that searches for such clues to the underlying construction of the virtual environment, is a kind of virtual-world naturalism, at once a return to an investigative urge that has been subsumed to the exhaustive mapping and description of the real world and a form of resistance to the very idea of pre-defined paths of action, of externally imposed limits, in virtual worlds as well as in our own.

    Fish, reptiles, and mammals can possess flexible dermal armor for protection. Here we seek to find the means by which Nature derives its protection by examining the scales from several fish (Atractosteus spatula, Arapaima gigas, Polypterus senegalus, Morone saxatilis, Cyprinius carpio), and osteoderms from armadillos, alligators, and leatherback turtles. Dermal armor has clearly been developed by convergent evolution in these different species. In general, it has a hierarchical structure with collagen fibers joining more rigid units (scales or osteoderms), thereby increasing flexibility without significantly sacrificing strength, in contrast to rigid monolithic mineral composites. These dermal structures are also multifunctional, with hydrodynamic drag (in fish), coloration for camouflage or intraspecies recognition, temperature and fluid regulation being other important functions. The understanding of such flexible dermal armor is important as it may provide a basis for new synthetic, yet bioinspired, armor materials. Copyright © 2013 WILEY-VCH Verlag GmbH & Co.

    Purpose: To improve the reliability by decreasing the number of dynamic equipments and safely shutdown the reactor core upon occurrence of accidents. Constitution: A pressure relief valve and a pressurizing tank or gravitational water falling tank disposed to the main steam pipe of a reactor are installed in combination. Upon loss-of-coolant accident, the pressure relief valve is opened to reduce the pressure in the reactor pressure vessel to the operation pressure for each of the tanks, thereby enabling to inject water in the pressurizing tank at first and, thereafter, water in the gravitational water falling tank successively to the inside of the pressure vessel. By utilizing the natural force in this way, the reliability can be improved as compared with the case of pumped water injection. Further, by injecting an aqueous boric acid to a portion of a plurality of tanks, if the control rod insertion becomes impossible, aqueous boric acid can be injected. (Takahashi, M.)

    Better stewardship of land is needed to achieve the Paris Climate Agreement goal of holding warming to below 2 °C; however, confusion persists about the specific set of land stewardship options available and their mitigation potential. To address this, we identify and quantify “natural climate solutions” (NCS): 20 conservation, restoration, and improved land management actions that increase carbon storage and/or avoid greenhouse gas emissions across global forests, wetlands, grasslands, and agricultural lands. We find that the maximum potential of NCS—when constrained by food security, fiber security, and biodiversity conservation—is 23.8 petagrams of CO2 equivalent (PgCO2e) y‑1 (95% CI 20.3–37.4). This is ≥30% higher than prior estimates, which did not include the full range of options and safeguards considered here. About half of this maximum (11.3 PgCO2e y‑1) represents cost-effective climate mitigation, assuming the social cost of CO2 pollution is ≥100 USD MgCO2e‑1 by 2030. Natural climate solutions can provide 37% of cost-effective CO2 mitigation needed through 2030 for a >66% chance of holding warming to below 2 °C. One-third of this cost-effective NCS mitigation can be delivered at or below 10 USD MgCO2‑1. Most NCS actions—if effectively implemented—also offer water filtration, flood buffering, soil health, biodiversity habitat, and enhanced climate resilience. Work remains to better constrain uncertainty of NCS mitigation estimates. Nevertheless, existing knowledge reported here provides a robust basis for immediate global action to improve ecosystem stewardship as a major solution to climate change.

  8. Which naturalism for bioethics? A defense of moderate (pragmatic) naturalism.

    Science.gov (United States)

    Racine, Eric

    2008-02-01

    There is a growing interest in various forms of naturalism in bioethics, but there is a clear need for further clarification. In an effort to address this situation, I present three epistemological stances: anti-naturalism, strong naturalism, and moderate pragmatic naturalism. I argue that the dominant paradigm within philosophical ethics has been a form of anti-naturalism mainly supported by a strong 'is' and 'ought' distinction. This fundamental epistemological commitment has contributed to the estrangement of academic philosophical ethics from major social problems and explains partially why, in the early 1980s, 'medicine saved the life of ethics'. Rejection of anti-naturalism, however, is often associated with strong forms of naturalism that commit the naturalistic fallacy and threaten to reduce the normative dimensions of ethics to biological imperatives. This move is rightly dismissed as a pitfall since ethics is, in part, a struggle against the course of nature. Rejection of naturalism has drawbacks, however, such as deterring bioethicists from acknowledging the implicit naturalistic epistemological commitments of bioethics. I argue that a moderate pragmatic form of naturalism represents an epistemological position that best embraces the tension of anti-naturalism and strong naturalism: bioethics is neither disconnected from empirical knowledge nor subjugated to it. The discussion is based upon historical writings in philosophy and bioethics.

  16. Legal nature of affatomia

    Directory of Open Access Journals (Sweden)

    Stanković Miloš

    2015-01-01

    Full Text Available In Salian and Ripuarian Code affatomia represented a bilateral legal transaction that was aimed at changing of the scoped of heirs determined by the customs, at least insofar being applied in the absence of biological descendants only. However, almost all further similarities in the field cease at this point. The form for using affatomia with Ripuarian Franks was much simpler than the one with the Salian Franks. Unlike the Salian Franks, affatomia could by all odds be used by Ripuarian Franks spouses in determining each other for a heir. Legal nature of the Salian Franks affatomia is most similar to the mancipatio familiae type of will in the Roman law (which does not mean it emerged from this law, while its form in the Ripuarian Code is much closer to testamentary adoption. As with Ripuarian Franks, affatomia seems to have definitely produced legal effects only after the death of the disposant, while its legal effects with the Salian Code performed inter vivos. Contemporary authors are trying to designate the legal nature of legal affairs from the early development of human and legal civilization through modern institutes that represent the completion of their evolutionary path. Taking the inheritance contract of the German or Swiss law, or the future assets donation of the French law, for example, and then comparing them to affatomia and thinx is an anachronism. This is evident by the fact that the legal nature of these ancient Germanic institutes can not be viewed unilaterally, but always through a combination of those institutes which we know today as adoption, gift or mixed donation with retention of different modalities for the transferor or the testator (usually usufruct. In this sense, if we are looking for a inheritance agreement in the Middle Ages, the contract in which a person determines other person for his/her universal or singular successor in the modern sense, we will certainly not find one. However, if within this institute we

    Natural is perceived as innately positive and is a widely sought-after attribute in food products. The natural food industry continues to grow in response to rising consumer demand. This qualitative study explored mothers' motivations for purchasing and consuming natural food products for themselves and their families. Mothers are an important population because of their disproportionate influence on household food consumption. We employed participant photography and a series of three weekly focus groups to derive a rich understanding of the activities surrounding and motivations behind seeking natural in everyday buying decisions. Five major themes were identified. First, natural nurtures well-being: physical, psychological, social, and emotional health. Second, natural behaves "supernaturally," allowing positive attributes to be transmitted from the source to the recipient. Third, natural is associated with authenticity, providing a sense of trust, transparency, and control. Fourth, consuming natural reinforces the socially constructed idea of a good mother. Lastly, the preference for natural does not always translate into purchase; mothers face compromises because of conflicting priorities and resources. Understanding mothers' multiple motivations provides deeper insight into the attraction for natural products. The findings have application in positioning interventions for more nutritional eating and revising regulations on the food label natural. Copyright © 2017 Elsevier Ltd. All rights reserved.
