    On the 21 of January of 2003, at 20:06:36 hrs (Mexico center time) an earthquake occurred at the Pacific coast with a magnitude of 7.6 degrees in the Richter scale, whose epicenter was located near the state of Colima and it was felt in a large extent of the Mexican Republic. The earthquake caused numerous material damages in the structures (houses, churches, offices, etc) and vital lines, mainly in the infrastructure of the electrical sector of the region, leaving without electrical energy a large part of the nearby populations and some colonies of distant zones such as in Mexico City. The cause of the interruption of the electrical energy was due to the collapse of some of the equipment of 400 and 230 KV of the electrical transmission substations, among which are Manzanillo II and Colima II. With the experience acquired in the earthquake of October 9, 1995 in Manzanillo, in which also the facilities and equipment of the electrical substations were affected considerably, and as a part of the infrastructure project on the analysis of seismic risk of vital lines that is being developed at this moment at the Instituto de Investigaciones Electricas (IIE), it was decided to inspect the electrical substations of the zone, where the greater damages in the facilities and equipment were reported, to analyze and to determine the main causes of their failure.

    Full Text Available After the increase in the demand for corn to produce ethanol last year, the international price of corn went up by 65%, which in turn made the tortilla price to go up between 40% and 100%. In response, both the federal and local governments triggered urgent actions to keep prices from increasing and affecting poor people. The purpose of this paper is to determine the factors that compose the demand function of tortilla. In addition, we want to specify the effect of a change in each of those factors. In particular, we wish to find out the effect of a price change in the consumption of tortilla. We conclude that in Colima- Villa de Álvarez the demand for tortilla has almost null price-demand elasticity. The main reason is that the tortilla is an inferior good in the sense that a price increase affects more to poor families than to rich ones.

    Colima volcano, also known as Volcan de Fuego (19° 30.696 N, 103° 37.026 W), is located on the border between the states of Jalisco and Colima and is the most active volcano in Mexico. Began its current eruptive process in February 1991, in February 10, 1999 the biggest explosion since 1913 occurred at the summit dome. The activity during the 2001-2005 period was the most intense, but did not exceed VEI 3. The activity resulted in the formation of domes and their destruction after explosive events. The explosions originated eruptive columns, reaching attitudes between 4,500 and 9,000 m.a.s.l., further pyroclastic flows reaching distances up to 3.5 km from the crater. During the explosive events ash emissions were generated in all directions reaching distances up to 100 km, slightly affected nearby villages as Tuxpan, Tonila, Zapotlán, Cuauhtemoc, Comala, Zapotitlan de Vadillo and Toliman. During the 2005 this volcano has had an intense effusive-explosive activity, similar to the one that took place during the period of 1890 through 1900. Intense pre-plinian eruption in January 20, 1913, generated little economic losses in the lower parts of the volcano due to low population density and low socio-economic activities at the time. Shows the updating of the volcanic hazard maps published in 2001, where we identify whit SPOT satellite imagery and Google Earth, change in the land use on the slope of volcano, the expansion of the agricultural frontier on the east and southeast sides of the Colima volcano, the population inhabiting the area is approximately 517,000 people, and growing at an annual rate of 4.77%, also the region that has shown an increased in the vulnerability for the development of economic activities, supported by the construction of highways, natural gas pipelines and electrical infrastructure that connect to the Port of Manzanillo to Guadalajara city.

    2010-12-01

    The Colima volcano, located in western Mexico (19° 30.696 N, 103° 37.026 W) began its current eruptive process in February 10, 1999. This event was the basis for the development of two volcanic hazard maps: one for ballistics (rock fall) lahars, and another one for ash fall. During the period of 2003 to 2008 this volcano has had an intense effusive-explosive activity, similar to the one that took place during the period of 1890 through 1900. Intense pre-Plinian eruption in January 20, 1913, generated little economic losses in the lower parts of the volcano thanks to the low population density and low socio-economic activities at the time The current volcanic activity has triggered ballistic projections, pyroclastic and ash flows, and lahars, all have exceeded the maps limits established in 1999. Vulnerable elements within these areas have gradually changed due to the expansion of the agricultural frontier on the east and southeast sides of the Colima volcano. On the slopes of the northwest side, new blue agave Tequilana weber and avocado orchard crops have emerged along with important production of greenhouse tomato, alfalfa and fruit (citrus) crops that will eventually be processed and dried for exportation to the United States and Europe. Also, in addition to the above, large expanses of corn and sugar cane have been planted on the slopes of the volcano since the nineteenth century. The increased agricultural activity has had a direct impact in the reduction of the available forest land area. Coinciding with this increased activity, the 0.8% growth population during the period of 2000 - 2005, - due to the construction of the Guadalajara-Colima highway-, also increased this impact. The growth in vulnerability changed the level of risk with respect to the one identified in the year 1999 (Suarez, 2000), thus motivating us to perform an update to the risk map at 1:25,000 using vector models of the INEGI, SPOT images of different dates, and fieldwork done in order

    Every year during the rainy season occur the problem of mass landslide in some areas of the community of Comala, Colima Mexico. Slope instability is studied in this volcanic region which is located in the southern part of the Volcan de Fuego de Colima. It occurs due to the combination of different factors existing in this area as: Precipitation, topography contrast, type and mechanical properties of deposits that constitute the rocks and soils of the region and the erosion due to the elimination of vegetation deck to develop and grow urban areas. To these geological factors we can extend the tectonic activity of the Western part of Mexico that originate high seismicity by the interaction of Cocos plate and North America plate forming the region of Graben de Colima, were is located this area. Here we will present a Zonification and determination of Slope Instability Risk Maps due to the rain and seismicity accelerators factors. This Study is parto of a proyect to reduce the risk of this phenomenon, it was carried out as part of the National Risk Map of Mexico analized using the CENAPRED methodology to zonificate the risk areas. The instability of slopes is determined both in its origin and in its development, by different mechanisms. In such a way that this process of instability can be grouped into four main categories: Falls or landslides, Flows, Slips and expansions or lateral landslides. Here it is presented the Risk analisis to this volcanic area that cover the municipality of Comala in the State of Colima, Mexico using the Susceptibility map, Risk Map and Risk analisis of the Municipality.

    To estimate potential health risks due to chronic ingestion of arsenic from groundwater in Colima, Mexico. Samples were randomly taken in 36 wells from 10 local aquifers. Analysis was performed by ICP-OES following international standards. Geostatistical interpolation was performed with ArcGIS, implementing a model weighting inverse distance to estimate arsenic routes of exposure and consumption on each locality. The Hazard Quotient Ratio (HQ) and carcinogenic risk (R) for As were estimated. The weighted average HQ for arsenic in Colima is 2.41. There are HQ> 1 values indicating adverse non-cancer health effects by continuous and prolonged intake of water with arsenic, which could affect 183 832 individuals in the state. The risk of developing any type of cancer among the population in this study due to high arsenic concentrations in groundwater (R) is 1.089E-3, which could statistically cause 446 cases of cancer. Current levels of arsenic in groundwater increase carcinogenic and non-carcinogenic human health risks in Colima.

    Colima volcano, also known as Volcan de Fuego (19 30.696 N, 103 37.026 W), is located on the border between the states of Jalisco and Colima, and is the most active volcano in Mexico. In January 20, 1913, Colima had its biggest explosion of the twentieth century, with VEI 4, after the volcano had been dormant for almost 40 years. In 1961, a dome reached the northeastern edge of the crater and started a new lava flow, and from this date maintains constant activity. In February 10, 1999, a new explosion occurred at the summit dome. The activity during the 2001-2005 period was the most intense, but did not exceed VEI 3. The activity resulted in the formation of domes and their destruction after explosive events. The explosions originated eruptive columns, reaching altitudes between 4,500 and 9,000 masl, further pyroclastic flows reaching distances up to 3.5 km from the crater. During the explosive events, ash emissions were generated in all directions reaching distances up to 100 km, slightly affecting the nearby villages: Tuxpan, Tonila, Zapotlan, Cuauhtemoc, Comala, Zapotitlan de Vadillo and Toliman. During 2005 to July 2013, this volcano has had an intense effusive-explosive activity; similar to the one that took place during the period of 1890 through 1905. That was before the Plinian eruption of 1913, where pyroclastic flows reached a distance of 15 km from the crater. In this paper we estimate the risk of Colima volcano through the analysis of the vulnerability variables, hazard and exposure, for which we use: satellite imagery, recurring Fenix helicopter over flights of the state government of Jalisco, the use of the images of Google Earth and the population census 2010 INEGI. With this information and data identified changes in economic activities, development, and use of land.

    We present early-stage results from a novel seismic investigation at Volcan de Colima. The project is a collaboration between the Observatorio Vulcanologico de la Universidad de Colima and the University of Alaska Fairbanks. In January 2006, twenty broadband seismometers were deployed in a wide-aperture array around the volcano as part of the IRIS/PASSCAL-supported Colima Volcano Deep Seismic Experiment (CODEX). They are scheduled to be in the field for eighteen months. Data from the first several months of the deployment have been used to characterize both the regional seismicity and the seismicity of the volcano, as recorded by the temporary array. Colima volcano has an unusually well-distributed suite of earthquakes on the local, regional and teleseismic scale. Data recorded close to the edifice provide an opportunity to explore the daily explosive activity exhibited by the volcano. The diversity of regional and teleseismic earthquake source regions make Colima an ideal place to probe the deep magmatic structure of a prodigous volcanic center. Results will be interpreted in the context of pre-existing petrologic models to address the relative role of crust and mantle in governing the evolution of an andesitic arc volcano.

    An ash sampling network was established arround Colima Volcano in 2005. Ash fall was sampled on the North, Northeast, East, Southeast, South, Southwest and West of the volcano. Samples were analyzed for ash components, geochemistry and leachates. Ash fall ocurred on April (12), May (10, 23), June (2, 6, 9, 10, 12, 14), July (27), September (27), October (23) and November (24). Most of the ash is made of andesitic dome-lithics but shows diferences in crystal, juvenile material and lithic content. In May, some samples contained grey and dark pumice (scoria). Texture varies from phi >4 to phi 0. Leachate concentration were low: SO4 (7.33-54.19) Cl- (2.29-4.97) and F- (0.16-0.37). During 2005, Colima Volcano's ash fall rotted some of the guava and peach fruits and had a drying effect on spearment and epazote plants. Even these small ash amounts could have hindered sugar cane and agave growth.

    Miranda, Javier; Zepeda, Francisco; Galindo, Ignacio

    2004-01-01

    An elemental composition study of atmospheric aerosols from the City of Colima, in the Western Coast of Mexico, is presented. Samples of PM 15 -PM 2.5 and PM 2.5 were collected with Stacked Filter Units (SFU) of the Davis design, in urban and rural sites, the latter located between the City of Colima and the Volcan de Colima, an active volcano. Elemental analyses were carried out using Particle Induced X-ray Emission (PIXE). The gravimetric mass concentrations for the fine fraction were slightly higher in the urban site, while the mean concentrations in the coarse fraction were equal within the uncertainties. High Cl contents were determined in the coarse fraction, a fact also observed in emissions from the Volcan de Colima by other authors. In addition to average elemental concentrations, cluster analysis based on elemental contents was performed, with wind speed and direction data, showing that there is an industrial contributor to aerosols North of the urban area. Moreover, a contribution from the volcanic emissions was identified from the grouping of S, Cl, Cu, and Zn, elements associated to particles emitted by the Volcan de Colima. - Elemental analyses of PM 15 in the City of Colima, Mexico, were done to identify possible contributions from the Volcan de Colima, an active volcano

    Full Text Available With the purpose of evaluating the risk of transmission of the Chagas disease in the State of Colima, México, an entomological survey was performed to obtain triatominae and the rate of infection by Trypanosoma cruzi determined by examination of its dejections. Two hundred eighteen houses located in 16 villages were sampled. In each house the intradomestic and peridomestic habitats were examined by the man-hour-house method, sensor boxes and mouse-baited traps. Also, 12 silvatic places were explored around the same areas using the same techniques as the ones sampled. In total, 456 specimens were captured, of which 139 correspond to Triatoma phyllosoma pallidipennis; 80 to T. p. longipennis; one specimen of T. dimidiata and 236 nymphs of Triatoma sp. Two hundred ninety seven insects were captured in the intradomestic habitat, 132 in the peridomestic and 26 in the silvatic. The index of positive houses was 27%, located in the central area of the state. The rate of natural infection with T. cruzi showed 25.6%. This results confirmed the presence of two important vectors of the Chagas disease in Colima. Its preference for the domestic habitat and its high levels of natural infection with T. cruzi suggested the existence of a significant risk for its transmission in this area of the country.

    Deep neural networks (NNs) are the state-of-the-art models for understanding the content of images and videos. However, implementing deep NNs in embedded systems is a challenging task, e.g., a typical deep belief network could exhaust gigabytes of memory and result in bandwidth and computational bottlenecks. To address this challenge, this paper presents an algorithm and hardware codesign for efficient deep neural computation. A hardware-oriented deep learning algorithm, named the deep adaptive network, is proposed to explore the sparsity of neural connections. By adaptively removing the majority of neural connections and robustly representing the reserved connections using binary integers, the proposed algorithm could save up to 99.9% memory utility and computational resources without undermining classification accuracy. An efficient sparse-mapping-memory-based hardware architecture is proposed to fully take advantage of the algorithmic optimization. Different from traditional Von Neumann architecture, the deep-adaptive network on chip (DANoC) brings communication and computation in close proximity to avoid power-hungry parameter transfers between on-board memory and on-chip computational units. Experiments over different image classification benchmarks show that the DANoC system achieves competitively high accuracy and efficiency comparing with the state-of-the-art approaches.

    Tuberculosis is a public health problem in Mexico. From 1999 to 2002, we assessed retrospectively the epidemiological, clinical, and treatment characteristics of pulmonary tuberculosis in the hospitals of the Mexican Institute of Public Health in the state of Colima (Mexico). We included 184 cases diagnosed with pulmonary tuberculosis. A database containing demographic, epidemiological, and clinical information was constructed and analyzed. We estimate a median patient delay of 83 d and a mean treatment delay of 2.3 d. Of 14 cases suspected for multiresistance and microbiologically assayed, 5 were found to carry a multi-drug-resistant strain. We also found a significant association between a short patient delay and the presence of hemoptysis (p = 0.002) or dyspnea (p<0.001). 86 patients (46.8%) were sputum smear microscopy negative at the end of treatment and 40 (21.7%) completed treatment giving an overall success rate of 68.5%, which compares unfavorably with the World Health Organization target success rate of 85%. Five (2.7%) patients failed treatment, 10 (5.4%) died, 39 (21.2%) interrupted treatment, and 4 (2.2%) transferred to another reporting unit. A 2002 strategic change in drug distribution seemed to prove successful.

Como variables independientes se analizaron la temperatura ambiental, la temporada, la aplicación de malatión en rociados a volumen ultrabajo (ULV, el índice de calidad de la vivienda (ICV y el grado de conocimientos, actitudes y prácticas (CAP. Resultados. Tanto el análisis de regresión logística multivariada como el de regresión lineal múltiple mostraron una reducción del IV y del C+/C atribuible a un efecto de la temporada seca. Paradójicamente, la temperatura mostró una correlación negativa con los índices larvarios, la cual se hizo más aparente en la temporada seca. El ICV tuvo la mayor asociación con el IV y con el C+/C, independientemente de las demás variables. Las nebulizaciones de malatión mostraron un discreto efecto negativo sobre los índices, mientras que los CAP no mostraron ninguna asociación con ellos. Conclusiones. Se concluye que la temperatura alta puede reducir el número de criaderos durante la temporada seca, que el ICV puede ser un buen estimador de la infestación por Ae. aegypti, que el uso de malatión ULV reduce los criaderos y que el índice de CAP presenta escasa asociación con la presencia de los mismos.Objective.

    The last eruptive processes of Colima volcano (November 1998- January 1999) was characterized by the occurrence of several seismic swarms. During the year previous to the eruption, the seismic activity developed in such a form that we could identified several stages in the evolution of the activity. By measuring the amplitude decay of coda waves we estimated coda attenuation Qc in the frequency range 2-10 Hz. We used Sato's (1977) single scattering model for coda windows of 10 to 15 seconds beginning at twice the S-wave travel time. We found a change in Q0 of approximately a 20-30% lower toward the end of the period. We also found that Qc was frequency dependent within this range. This dependence was progressively lower until the last month of activity just before the eruption. Studies of the same type that have been carried out in other volcanoes (Fehler, et al., 1998, Londoño, 1996) showed changes in the attenuation of the seismic waves related to volcanic eruptions. Changes of coda Q can be attributed to the change of density of the open microcracks in the rocks because of the pressure generated by the pushing of magma toward the surface which is also responsible for the inflation of the volcanic edifice.

Os tratamentos avaliados foram: controle (sem dano mecânico, dano mecânico por impacto, dano mecânico por compressão e dano mecânico por corte. Os diferentes danos não influenciaram na firmeza de polpa e no ângulo 'hue' da casca. O dano por corte proporcionou frutos com menor acidez titulável, nove dias após a aplicação do dano. Frutos submetidos ao dano por impacto apresentaram maior teor de sólidos solúveis, quinze dias após a aplicação dos danos. Os danos por impacto e corte causaram o menor valor de L da polpa em todas as avaliações, evidenciando o escurecimento da polpa. Contudo, este efeito não foi observado na epiderme. Todos os frutos danificados por corteapresentaram podridão após nove dias da aplicação dos danos.De maneira geral, pode-se concluir que, nas intensidades testadas, maçãs 'Fuji Suprema' submetidas ao dano por impacto e corte apresentam prejuízos em sua qualidade, pois ocorre escurecimento da polpa no local do dano. Além disso, o dano por corte reduz a vida pós-colheita dos frutos, facilitando a ocorrência de podridões.

    Didelphostrongylus hayesi is an important and prevalent pulmonary nematode in the opossum ( Didelphis virginiana ). An in-depth description of the pulmonary lesions caused by this nematode is lacking. The objective of this investigation was to make a detailed account of the gross, subgross, and microscopic changes that occur in the lungs of opossums naturally infected with D. hayesi. Forty-four opossums trapped in the state of Colima, Mexico, were euthanized by an overdose of barbiturates. Following a postmortem examination, the right lung was cut from the main bronchi and placed in a Petri dish containing a saline solution for the detection and identification of live parasites. The left lung was fixed and cut serially for subgross microscopic examination and sections of lung were cut and stained for histopathologic examination. The most remarkable gross change in parasitized lungs was a poorly collapsible pulmonary parenchyma and mild emphysema. The right lung tested positive for lungworms on gross examination in 20/44, and 11/44 (25%) of the left lungs showed tan nodules on the pleural surface. Microscopically, the bronchi of 20/44 animals harbored adult and larval stages of D. hayesi (left lung), the same 20 opossums from which nematodes were grossly evident at necropsy (right lung). Adults and larvae were present in bronchi, bronchioles, and alveoli mixed with desquamated cells and many eosinophils, and to a lesser extent neutrophils, alveolar macrophages, and giant cells. Bronchi and bronchioles exhibited goblet cell hyperplasia and metaplasia respectively, and infiltration of lymphoplasmacytic cells in the interstitium and lamina propria. The tan nodules consisted of focal alveolar endogenous lipidosis, which likely resulted from parasitic airway obstruction. The lungs of 3/20 parasitized opossums also showed alveolar bronchiolization (Lambertosis). The absence of Eucoleus aerophilus or bacterial pneumonia incriminates D. hayesi as the putative cause of

O MRFV é freqüentemente encontrado em infecções mistas com fitoplasmas e espiroplasmas, causando as doenças denominadas enfezamentos do milho. Em uma lavoura de milho próxima a Santo Antonio da Posse, SP, cercada por campos de cana-de-açúcar, foi encontrada alta incidência de plantas apresentando mosaico, riscas, nanismo e espigas com falhas no enchimento de grãos. Análises serológicas com anti-soros específicos detectaram a presença do SCMV e MRFV nessas plantas. A infecção pelo SCMV também foi confirmada por RT-PCR com primers específicos e análise de seqüências. Em observações de preparações contrastadas negativamente em TEM, partículas flexuosas (ca.770 nm e isométricas (ca.30 nm foram detectadas. Em cortes ultrafinos, inclusões citoplasmáticas, típicas de Potyviridae, foram observadas; não foi encontrada a presença de espiroplasmas nem de fitoplasmas. Esses resultados mostram que a infecção conjunta por SCMV e MRFV pode ser responsável pelos danos encontrados nessa lavoura.The two main viruses infecting maize in Brazil are Sugarcane mosaic virus (SCMV and Maize rayado fino virus (MRFV, whose main vectors are the aphid Rhopalosiphum maidis and the leafhopper Dalbulus maidis, respectively.

This essay is a case of the influence of transnational company Coca Cola in the formation of the region of Tecoman, Colima, as providing an input to the company during the period dominated by Fordism. This region is formed from exogenous impulses of the needs of lemon essential oil by transnational companies which in turn have determined the stages of growth and expansion in the region that occur in phases of boom and bust.

    Full Text Available The paper examines the possible relationship of anomalous variations of different atmospheric and ionospheric parameters observed around the time of a strong earthquake (Mw 7.8 which occurred in Mexico (state of Colima on 21 January 2003. These variations are interpreted within the framework of the developed model of the Lithosphere-Atmosphere-Ionosphere coupling. The main attention is focused on the processes in the near ground layer of the atmosphere involving the ionization of air by radon, the water molecules' attachment to the formed ions, and the corresponding changes in the latent heat. Model considerations are supported by experimental measurements showing the local diminution of air humidity one week prior to the earthquake, accompanied by the anomalous thermal infrared (TIR signals and surface latent heat flux (SLHF and anomalous variations of the total electron content (TEC registered over the epicenter of the impending earthquake three days prior to the main earthquake event. Statistical processing of the data of the GPS receivers network, together with various other atmospheric parameters demonstrate the possibility of an early warning of an impending strong earthquake.

    Dengue fever is considered to be one of the most important arboviral diseases globally. Unsuccessful vector-control strategies might be due to the lack of sustainable community participation. The state of Colima, located in the Western region of Mexico, is a dengue-endemic area despite vector-control activities implemented, which may be due to an insufficient health economic analysis of these interventions. A randomized controlled community trial took place in five urban municipalities where 24 clusters were included. The study groups ( n = 4) included an intervention to improve the community participation in vector control (A), ultra-low volume (ULV) spraying (B), both interventions (AB), and a control group. The main outcomes investigated were dengue cumulative incidence, disability-adjusted life years (DALYs), and the direct costs per intervention. The cumulative incidence of dengue was 17.4%, A; 14.3%, B; 14.4%, AB; and 30.2% in the control group. The highest efficiency and effectiveness were observed in group B (0.526 and 6.97, respectively) and intervention A was more likely to be cost-effective ($3952.84 per DALY avoided) followed by intervention B ($4472.09 per DALY avoided). Our findings suggest that efforts to improve community participation in vector control and ULV-spraying alone are cost-effective and may be useful to reduce the vector density and dengue incidence.

    In the hypothetical case of a nuclear reactor severe accident, the reactor core could melt and form a mixture of nuclear fuel (UO 2 + Fission Products), metallic or oxidized cladding + steel, called c orium , of highly refractory oxides (UO 2 , ZrO 2 ) and metallic or oxidized steel, that could eventually flow out of the vessel and mix with the substrate decomposition products (generally oxides such as SiO 2 , Al 2 O 3 , CaO, Fe 2 O 3 ). The French Atomic Energy Commission (CEA) has launched a R and D programme aimed at providing the tools for improving the mastering of severe accidents. It encompasses the development of models and codes, performance of experiments in simulant and prototypic materials and the analysis of international experiments. The experiments with prototypic corium (i.e. material containing depleted UO 2 ) are performed in the PLINIUS experimental platform at CEA Cadarache. It comprises the VULCANO facility for 50-100 kg tests (corium-material interactions, corium solidification etc.), the COLIMA facility for smaller scale (∼1 kg) experiments, the VITI facility for corium properties measurement and the KROTOS facility for corium-water interaction (a few kg). In the framework of the 5 th European Framework Programme, free trans-national access to these facilities has been offered to EU and Associated States researchers. For the first PLINIUS access, COLIMA experiments have been conducted with a Bulgarian Team (TU/SOFIA, BAS/INRNE and NPP/KOZLODUY). This series of tests was devoted to experimental studies on fission products release and corium behaviour in the late phase in a hypothetic case of severe accident in a PWR type VVER-440. The COLIMA experimental results are consistent with previous experiments on irradiated fuels (VERCORS, PHEBUS) with small differences for some fission products and show new results for the remaining corium. For the second visit, scientific users from FZK in Germany were selected to validate the COMET core

Os resultados mostraram que houve um nível diferenciado no ataque de G. molesta em brotações e frutos, entre as cultivares. As avaliações de danos em brotações mostraram que, até a fase de colheita, a cultivar Ouro foi a mais atacada, sendo superada pela 'Chimarrita' quando se inclui os danos ocorridos na fase pós-colheita. Em frutos, a 'Marli' apresentou o maior número de pêssegos danificados entre as seis cultivares avaliadas.This paper deals with the occurrence and damage of Grapholita molesta (Lepidoptera: Tortricidae in a commercial peach orchard with six cultivars of different fruit ripening cycles: precocious ('São Pedro ', medium ('Chimarrita ', 'Ouro ', 'Coral ' and 'Marli ' and late ('BR II ', in Araucaria, State of Paraná, Brazil. Five plants of each cultivar were selected for evaluating the damages in shoots and fruits. The damages were accumulated and evaluated in three phases: previous thinning, stone hardening and harvesting. The results were as follows: the cultivar "Ouro" was the most damaged one up to the harvesting phase, although 'Chimarrita' surpassed 'Ouro' when the damages observed in the post-harvesting phase were included. Among the six cultivars, 'Marli' was the one presenting the highest number of damaged fruits.

    The main purpose of this study is to calculate the COLIMA CA-U3 experimental test with the ELSA module of the ASTEC code. This experimental test was performed to represent the fission product and structural material releases from a VVER-440 magma type configuration. Thus, some additional work is also done on test result analyses and corresponding ASTEC parameter usage to model as closely as possible the test configuration. Code results on fission product releases are compared to experimental results in a qualitative way for all elements that can be evaluated by the ASTEC code. Sensitivity cases are also performed on the gas flow rate carrying the fission product. (author)

    Activity at Volcán de Colima has increased over the past 8 years, and is possibly building towards a significant eruption. Monitoring its current activity is therefore critical, with recent expansion of the network providing new types of data which need to be understood. Recent activity has consisted of 3 effusive episodes lasting up to 22 months, separated by periods characterised by daily Vulcanian eruptions of small to moderate size; the largest producing pyroclastic flows reaching over 5 km, representing the most significant since the last Plinian event (1913). A model has been proposed to explain the mechanism of the Vulcanian explosions, derived through integrating different data including seismicity, SO2 flux and the ascent velocity and thermal emission of the eruption column. Infrasound measurements have helped to demonstrate the variability in the distribution of energy produced by the events. Swarms of low frequency seismic events were associated with the largest magnitude explosions and have been examined statistically with variations observed in the magnitude-frequency relationship of each swarm and their distribution. Seismic evidence of migration of the source has been identified, maybe explained by brittle fracturing associated with an increasing pressure differential within the conduit system. Volcán de Colima has a complex edifice structure with explosions switching between multiple vents and showing pulsing. Variation in remotely monitored fumarole temperatures has also been related to the explosive activity. It is clear that small variations of certain critical factors within the conduit system can lead to a transition between effusive and explosive activity. Frequent transitions at Volcán de Colima provide an ideal opportunity to analyse variations in the observable signals and deduce relationships with changes within the conduit that influence magma ascent and degassing, such as its volatile contents or ascent velocity.

    Volcán de Colima, the most active volcano in Mexico, started a new eruptive cycle in January 2013. Since this date, the volcano has presented effusive and explosive activity. The beginning of the cycle was marked by a moderate Vulcanian explosion which had hyperbolical behavior in its precursory seismicity, possibly related to a shallow rupture process. Then, during the whole eruptive stage, the effusive activity was accompanied by low to moderate explosions. The explosions had energies mainly of 106 joules and were located between 0 and 1600 m below the crater, whereas the locations of tremor sources were found to be deeper, reaching up to 3800 m beneath the crater. Very-long-period signals (VLPs) have been observed with Vulcanian explosions that produce pyroclastic flows. A few number of volcano-tectonic events (VTs) were recognized during the studied period (2013-2015), indicating that the volcano is an open system. This was particularly evidenced in July 2015, when a new batch of magma rose rapidly without large precursors, only an accelerated increase in the number of rockfalls and associated RSEM. This event generated two large lava dome collapses with several pulses of material and pyroclastic flows that travelled up to 10.3 km from the summit. The seismic monitoring of Volcán de Colima is currently the only tool in real-time employed to assess the state of the volcanic activity. It is thus necessary to integrate new seismic methods as well as other geophysical monitoring techniques able to detect precursory signals of an impending hazardous event.

    This short paper reports on new {sup 14}C datings of debris flow units from the Nevado de Colima and Fuego de Colima volcanoes in Mexico. These new datings in connection with a detailed stratigraphic study in the deep canyons around the volcanoes has revealed an exceptional recurrence of flank destabilizations of the Fuego de Colima during the last 45000 years. The cumulated volume of debris in the whole Colima massif is estimated to 60-100 km{sup 3}. The correlation between Landsat satellite pictures and the distribution and age of the debris flows shows that both volcanoes are made of several post-destabilization remaining structures, and that both volcanoes were active and simultaneously collapsed 18500 years ago. The numerous fluvial-lacustrine sequences intercalated between the successive flows indicate that the debris flow were partially sedimented under water and could have led to catastrophic tsunamis towards the Pacific coast. Implications of this work are important because a population of more than 200000 inhabitants is living in a zone covered by several debris flows. (J.S.).

  7. Caldera formation at Volcán Colima, Mexico, by a large large holocene volcanic debris avalanche

    1988-12-01

    About 4,300 years ago, 10 km 3 of the upper cone of ancestral Volcán Colima collapsed to the southwest leaving a horseshoe-shaped caldera 4 km in diameter. The collapse produced a massive volcanic debris avalanche deposit covering over 1550 km 2 on the southern flanks of the volcano and extending at least 70 km from the former summit. The avalanche followed a steep topographic gradient unobstructed by barriers, resulting in an unusually high area/volume ratio for the Colima deposit. The apparent coefficient of friction (fall height/distance traveled) for the Colima avalanche is 0.06, a low value similar to those of other large-volume deposits. The debris avalanche deposit contains 40-75% angular volcanic clasts from the ancestral cone, a small proportion of vesicular blocks that may be juvenile, and in distal exposures, rare carbonate clasts plucked from the underlying surface by the moving avalanche. Clasts range in size to over 20 m in diameter and are brecciated to different degrees, pulverized, and surrounded by a rock-flour matrix. The upper surface of the deposit shows prominent hummocky topography with closed depressions and surface boulders. A thick, coarse-grained, compositionally zoned scoria-fall layer on the upper northeastern slope of the volcano may have erupted at the time of collapse. A fine-grained surge layer is present beneath the avalanche deposit at one locality, apparently representing an initial blast event. Most of the missing volume of the ancestral volcano has since been restored at an average rate of 0.002 km 3/yr through repeated eruptions from the post-caldera cone. As a result, the southern slope of Volcán Colima may again be susceptible to collapse. Over 200,000 people are now living on primary or secondary deposits of the debris avalanche, and a repetition of this event would constitute a volcanic disaster of great magnitude. Ancestral Volcán Colima grew on the southern, trenchward flank of the earlier and larger volcano Nevado de

A precificação do dano ambiental é exigida em laudos periciais e o uso de modelos de valoração tornou-se frequente. O método do custo de restauração é geralmente usado na avaliação de danos ambientais. Porém, a sua utilização como método único negligencia as funções ambientais perdidas pelo ecossistema e torna o dano lucrativo para o infrator. O exame pericial deve considerar também os danos indiretos, cuja mensuração econômica é matéria controversa. Nesse sentido, há recomendações de aplicação de taxas de juros como forma de compensar os danos indiretos e as perdas ecossistêmicas provisórias em locais degradados. A aplicação dessas taxas, porém, deve resguardar uma relação de proporcionalidade e coerência com os padrões de recuperação ambiental, devido aos princípios da razoabilidade e proporcionalidade. Nesse sentido, taxas simples e compostas de juros mostraram-se discrepantes com a função descrita por sistemas biológicos e ecológicos em fase de recuperação. A aplicação de juros compostos decrescentes mostrou-se proporcional aos padrões de recuperação de funções ecossistêmicas e pode ser utilizada para a valoração de danos indiretos em perícias ambientais.

    Sudden transitions from effusive to explosive eruptive behaviour have been observed at several volcanoes. As a result of explosive activity, pyroclastic density currents represent a major threat to life and infrastructure, mostly due to their unpredictability, mass, and velocity. Difficulties in direct observation force us to deduce crucial information from their deposits. Here, we present data from field work performed in 2009 on primary deposits from recent explosive episodes at Volcán de Colima (Mexico) and Tungurahua (Ecuador). Volcán de Colima, located 40km away from the Capital city Colima with 300,000 inhabitants, has been active since 1999. Activity has been primarily characterized by the slow effusion of lava dome with the daily occurrence of episodic gas (and sometimes ash) explosion events. During a period of peak activity in 2005, explosive eruptions repeatedly destroyed the dome and column collapse resulted in several PDCs that travelled down the W, S, and SE flanks. Tungurahua looms over the 20,000 inhabitants of the city of Baños, located 5km away, and is considered one of the most active volcanoes in Ecuador. The most recent eruptive cycle began in 1999 and climaxed in July and August of 2006 with the eruptions of several PDCs that traveled down the western flanks, controlled by the hydrological network. During two field campaigns, we collected an extensive data set of porosity and grain size distribution on PDCs at both volcanoes. The deposits have been mapped in detail and the porosity distribution of clasts across the surface of the deposits has been measured at more than 30 sites (> 3.000 samples). Our porosity distribution data (mean porosity values range between 17 and 24%) suggests an influence of run out distance and lateral position. Preliminary results of grain size analysis of ash and lapilli (structures such as dunes, grain size distribution, and the observed damage to vegetation help depict the progression of the flow and its

    The thermal conductivity (K), specific heat (Cp) and the coefficient of heat transfer surface (H) are the basic parameters to describe the process of cooling a volcanic rock fragment released in an explosive event. The analysis of the cooling process by conduction, convection and radiation of heat in volcanic rock fragments, has been limited to basalts, and various minerals such as olivine, pyroxene, quartz, etc. (Miao & Chen, 2014; Branlund & Hofmeister, 2012; Romine et al, 2012;. Schön, 2011; Stroberg et al, 2010;. Schatz & Simmons, 1972). There are no detailed studies on the thermal properties of the andesites, abundant in continental stratovolcanoes, and particularly susceptible from lava domes with frequent destruction processes, such as Popocatepetl and Volcan de Colima. Previously, we developed an algorithm for calculation of the grain-size distribution, degree of fragmentation, the thermal energy released and its possible correlation with Volcanic Explosive Index (VEI) from the cooling curves of fragments from vulcanian and strombolian explosions. These curves were obtained from sequences of time over incandescent deposits recorded at selected pixel thermal images of vulcanian activity in the Popocatepetl and Volcan de Colima, Mexico. However, the model was limited by the lack of thermal parameters of the andesites, forcing a first approximation using basalts data. We present a simple model for the cooling process using andesites samples from Popocatépetl and Volcan de Colima. First, the samples were subjected to a rounding process to minimize surface effects. Then, heated to 800 ° C were extracted from the muffle and cooling rate is measured. The thermal conductivity and coefficient of surface heat are determined using a thermal camera and three thermocouples embedded at various depths within the sample. An inversion method was implemented to determine the thermal properties parameters , by comparing the observed data regarding cooling model for a solid

    The Atenquique river basin drains the eastern sector of the Volcanic Complex (VC) Volcan-Nevado de Colima, located on the border of the states of Jalisco and Colima. To use the digital geomorphological analysis 1:50000 scale mapping provided by INEGI and Landsat images, manipulating it in ArcGIS 10.2 developing the DEM that was the basis for morphometric characterization. The results show that the basin is divided into five sub-basins, with the main Atenquique (SAT) and Arroyo Seco (SAS), calculating the compactness coefficient (Kc) and the coefficient of sinuosity indicate that SAT is the most prone to floods due to straight and slightly sinuous channels. However, the density of dissection shows a more developed drainage network on the SAT, with slopes up to 84° and 600 m deep. The drainage basin has its source at an altitude of 4260 m and its mouth is in the Tuxpan River at 1040 m, which has a relative height of 2800 m; has a funnel-shaped elongated west-east, its outstanding average in the sector are Mountain 44° and 10° the piedmont. The SAT has a total area of 81.8 km2, with a dendritic river network, where the first order streams reach an 82.99%, and second order streams are the 13.4% of the total, these values show that most of the slopes of the basin have incipient development valleys and steep slopes. The basin has had 3 debris flows in recent 58 years; these are formed by large volumes of rock and mud that covered the town of Atenquique and paper mill located at the mouth of the Tuxpan River, caused deaths and significant economic damage.

    The study and preservation of tsunami deposits have being challenging in humid tropical environments. While tsunami deposits have been widely studied at temperate latitudes, few studies assess this problem in tropical environments due to the difficulties intrinsic to these places (e.g. tsunami deposit preservation, post-burial changes in a tropical environment, mangrove vegetation, difficult access, wildlife, among others). Here we assess the problem of tsunami-deposits preservation on the Jalisco-Colima tropical coast of Mexico, which parallels the more than 1000-km long Mexican subduction, where historical accounts indicate the occurrence of two significant tsunamis on June 3 and 22, 1932 (Corona and Ramírez-Herrera, 2012a, Valdivia et al., 2012). However, up to date, no geological evidence of these events has been reported. We present geological evidence of two large tsunamis related to the June 3, M 8.2 earthquake, and the June 22, Ms 6.9 landslide-triggering event of 1932 (Corona and Ramírez-Herrera, 2012a, b). A multiproxy approach was applied to unravel the nature of anomalous sand units and sharp basal contacts in the stratigraphy of a number of sites at Palo Verde estuary, El Tecuán swales and marsh, and La Manzanilla swales, on the Jalisco-Colima coast. Lines of evidence including historical, geomorphological, stratigraphic, grain size, organic matter content, microfossils (diatoms and foraminifera), geochemical content, magnetic susceptibility and AMS analyses, together with dating (210Pb and 14C), and modeling, corroborate the presence of tsunami deposits of both the 3 June 1932 tsunami at El Tecuán and La Manzanilla, and the 22 June 1932 tsunami at Palo Verde. Further evidence of earlier tsunamis, at least four events, is also evident in the stratigraphy. Work in progress should reveal the chronology of the earliest tsunamis and their origin.

    Highlights: ► Experiment investigating aerosol retention within concrete containment cracks under nuclear severe accident conditions. ► Provided representative conditions of the aerosols suspended inside the containment of PWRs under a severe accident. ► Prototypical aerosol particles generated with a thermite reaction and transported through the crack sample reproducing surface characteristics, temperature, pressure drop and gas leakage. ► The results indicate the significant retention due to zig-zag path. -- Abstract: CEA and RSE managed an experimental research concerning the investigation of aerosol retention within concrete containment cracks under severe accident conditions. The main experiment was carried out in November 2008 with aerosol generated from the COLIMA facility and a sample of cracked concrete with defined geometric characteristics manufactured by RSE. The facility provided representative conditions of the aerosols suspended inside the containment of PWRs under a severe accident. Prototypical aerosol particles were generated with a thermite reaction and transported through the crack sample, where surface characteristics, temperature, pressure drop and gas leakage were properly reproduced. The paper describes the approach adopted for the preparation of the cracked concrete sample and the dimensioning of the experimental apparatus, the test procedure and the measured parameters. The preliminary results, obtained from this single test, are also discussed in the light of the present knowledge about aerosol phenomena and the theoretical analyses of particle behaviour with the crack path.

    Full Text Available The relationship between wood growth and environmental variability at the tropical treeline of North America was investigated using automated, solar-powered sensors (a meteorological station and two dendrometer clusters installed on Nevado de Colima, Mexico (19° 35’ N, 103° 37’ W, 3,760 m a.s.l.. Pure stands of Pinus hartwegii Lindl. (Mexican mountain pine were targeted because of their suitability for tree-ring analysis in low-latitude, high-elevation, North American Monsoon environments. Stem size and hydroclimatic variables recorded at half-hour intervals were summarized on a daily timescale. Power outages, insect outbreaks, and sensor failures limited the analysis to non-consecutive months during 2001–2003 at one dendrometer site, and during 2002–2005 at the other. Combined data from the two sites showed that maximum radial growth rates occur in late spring (May, as soil temperature increases, and incoming short-wave radiation reaches its highest values. Early season (April–May radial increment correlated directly with temperature, especially of the soil, and with solar radiation. Stem expansion at the start of the summer monsoon (June–July was mostly influenced by moisture, and revealed a drought signal, while late season relationships were more varied.

    By means of the concession institute, the administration provides, indirectly, its originary functions gestion, acting and stimulating the development of the private activity with the exclusive attribution to the particulars, of rights and faculties, having always as a bigger aim the public interest. That being so, with the advent of the Amendment number 9 of the 1988 Federal Constitution, the State went by realizing concessions in the petroleum and natural gas field, allowing the market aperture, which was, before the amendment, monopolized by a state company - PETROBRAS. However, in spite of concede the exploration, production and transport rights of this product, the State keep itself playing the role of the collective interest prosecutor, and in such case, must be responsible for the damages that perhaps its concessionaires cause. The present research is purposed to study specifically the environment damages caused by the petroleum industry concessionaires, in what concerns to the state civil responsibility, using the many interpretative methods of the Law, like the historical, the systematic and the teleological, in the scope of contribute for a juridic culture each time stronger in the defense of the diffuse rights, in specific the environment rights.

    Full Text Available A cirurgia de controle de danos é um conceito amplamente aceito atualmente entre os especialistas em trauma abdominal quando se trata de doentes gravemente traumatizados. Nestes pacientes a morte decorre, na maioria das vezes, da instalação da tríade letal (hipotermia, coagulopatia e acidose e não da incapacidade de reparar as graves lesões presentes. Nesta revisão, os autores abordam a tríade letal, em suas três fases, e enfatizam as medidas adotadas para preveni-las. Além de discutirem a indicação e o emprego da cirurgia para o controle de danos em seus vários estágios. A restauração dos padrões fisiológicos do doente na UTI, para que o mesmo possa ser submetido à operação definitiva e ao fechamento da cavidade abdominal, outro desafio no paciente traumatizado grave, também é discutida.The damage control surgery is a widely accepted concept today among abdominal trauma specialists when it comes to the severely traumatized. In these patients, the death is due, in most cases, to the installation of the lethal triad (hypothermia, coagulopathy and acidosis and not the inability to repair the serious initial damage. In this review, the authors address the lethal triad in its three phases and emphasize the measures taken to prevent them, as well as discussing the indication and employment of damage control surgery in its various stages. Restoring the physiological status of the patient in the ICU, so that he/she can be submitted to final operation and closure of the abdominal cavity, another challenge in severe trauma patients, is also discussed.

    A macroseismic methodology of seismic risk microzonation in a low-rise city based on the vulnerability of residential buildings is proposed and applied to Colima city, Mexico. The seismic risk microzonation for Colima consists of two elements: the mapping of residential blocks according to their vulnerability level and the calculation of an expert-opinion based damage probability matrix (DPM) for a given level of earthquake intensity and a given type of residential block. A specified exposure time to the seismic risk for this zonation is equal to the interval between two destructive earthquakes. The damage probability matrices were calculated for three types of urban buildings and five types of residential blocks in Colima. It was shown that only 9% of 1409 residential blocks are able to resist to the Modify Mercalli (MM) intensity VII and VIII earthquakes without significant damage. The proposed DPM-2007 is in good accordance with the experimental damage curves based on the macroseismic evaluation of 3332 residential buildings in Colima that was carried out after the 21 January 2003 intensity MM VII earthquake. This methodology and the calculated PDM-2007 curves may be applied also to seismic risk microzonation for many low-rise cities in Latin America, Asia, and Africa.

    In January 2013 eruptions resumed at Volcán de Colima, the previous activity having ceased in June 2011. This period represented the quietest the volcano has been since before the previous episode commenced in 1998. The new eruptive episode is showing differences compared to the 1998-2011 period, which are presenting a challenge to interpret. Lower gases fluxes coupled with lower fumaroles temperatures are consistent with the decreasing trend of volatile-contents but the two larger Vulcanian eruptions in January produced pyroclastic density currents with a greater degree of fragmentation than previous events. A dome has been growing within the newly formed crater within the previous dome. The 1998-2011 eruption included five periods of effusive activity, with little variation in composition. Domes grew with effusion rates covering more than 2 orders of magnitude. Both explosive and effusive activity was centred at multiple locations within the summit crater. The SO2 flux showed a general declining trend throughout this period and 2005 included the largest pyroclastic flows witnessed since the last Plinian eruption in 1913. Swarms of small amplitude long period events were detected prior to each larger eruption, these have been again witnessed in 2013. The characteristics of the swarms is being compared, the generation of events being related to brittle fracturing along the conduit margin. The episode terminated in June 2011 with an explosion which removed the upper portion of the most recent and extended period of dome growth, which was at a very slow rate from January 2007. Automated 3D computer vision reconstruction techniques (structure-from-motion and multi-view stereo, SfM-MVS) have permitted the estimation of dome volumes from 1 m resolution digital elevation models. A small decrease in volume (0.4×105 m3) was detected prior to the explosion, which was related to the formation of steps in the dome surface, related to localized zones of weakness. For the

Dois experimentos sobre simulação do dano larval foram realizados testando um equipamento cujo componente principal é uma lâmina metálica em forma de U, para corte das raízes. Raízes das cultivares BR-Irga 414 e Bluebelle, de ciclo biológico curto, e suscetíveis ao inseto e BR-Irga 410 e Dawn, de ciclo médio e resistentes, foram submetidas aos tratamentos de (1 corte artificial, com o simulador, (2 corte natural, pelas larvas e (3 sem corte, artificial ou natural, protegidas com inseticida. A simulação foi praticada na fase vegetativa das plantas, 31 dias pós-irrigação por inundação, época do pico da população larval nas raízes. Avaliaram-se dados sobre comprimento, peso de matéria seca e volume de raízes, imediatamente após a aplicação do tratamento de simulação e na pré-emissão de panículas, população larval em plantas submetidas ao dano natural, e produtividade de grãos. Na avaliação efetuada imediatamente após a simulação, em todas as cultivares, não ocorreu diferença entre índices de dano às raízes resultantes do uso do simulador e da alimentação de larvas. Na fase de pré-emissão das panículas, os índices de recuperação do sistema radicular das plantas submetidas aos danos natural e artificial, também foram similares. As cultivares de ciclo médio apresentaram maior recuperação dos tecidos radiculares e menor perda de produtividade de grãos, confirmando o maior grau de resistência a O. oryzae. Concluiu-se que o método de simulação é aplicável em pesquisas sobre resistência de arroz ao inseto, principalmente na identificação de genótipos tolerantes.

    Colima volcano is an andesitic stratovolcano located in the western part of the Trans-Mexican Volcanic Belt (TMVB) and at the southern end of the N-S trending Colima graben, about 70 km from the Pacific Ocean coast. It is probably the most active Mexican volcano in historic time and one of the most active of North America. Colima volcano yielded numerous partial edifice collapses with emplacement of debris avalanche deposits (DADs) of contrasting volume, morphology, texture and origin. This work has the aim to provide the evidences of how the climatic condition during the 13 ka flank collapse of the Colima volcano affected the textural characteristic and the mobility of the debris avalanche and debris flow originated from this event that occurred just after the Last Glacial Maximum in Mexico (18.4-14.5 ka 14C BP with snow line at 3600 m a.s.l. up to 13 ka BP). The 13,000 yrs old debris avalanche deposit, here named Tonila (TDAD) presents the typical debris avalanche textural characteristics (angular to sub-angular clasts, coarse matrix, jigsaw fit) but at approximately 13 km from the source, the deposit transforms to an hybrid phase with debris avalanche fragments imbedded in a finer, homogenous and indurated matrix more similar to a debris flow deposit. The debris avalanche deposit is directly overly by debris flows, often more than 10 m thick that contains large amount of logs from pine tree, mostly accumulated toward the base and imbricated down flow. Fluvial deposits also occur throughout all successions, representing periods of stream and river reworking highly localized and re-establishment. All these evidences point to the presence of water in the mass previous to the failure. The event here described represent an anomalous event between the previously described deposit associated to volcanic complex, and evidence as climatic condition can alter and modifies the depositional sequences incrementing the hazard.

    The conversion of natural ecosystems into agricultural land affects the atmospheric CO2 concentration whose increase contributes to global warming. In the low activity clay soils (LAC) of the tropics, farming is largely dependent on the level of soil organic carbon (SOC) for sustainable crop production. In this study, we investigated the changes in SOC in Plinthosols along a cultivation chronosequence in the Dano district (Southwest Burkina-Faso). The chronosequence consisted of undisturbed savannah (Y0) and 11 agricultural fields with short and long histories of cultivation ranging from 1-year-old cropland to 29-year-old cropland (Y29). About 14 soil profiles were described and soil composite samples were taken per horizon. Particulate organic matter (POM) was fractionated according to particle size: fraction 2000 - 250 μm (POM1), 250 μm - 53 μm (POM2), 53 μm - 20 μm (POM3), and POM1 > POM3 > POM2 carbon no matter the duration of land use. However, SOC losses occurred not only in the labile C pools but also in the stabile nonPOM fraction with increasing duration of agricultural land use. Compared to the initial carbon content in the Y0 field, about 59% of carbon content loss occurred in the POM1 (> 250 μm), 53% in the POM2 (250 - 53 μm), 52 % in the POM3 (53 - 20 μm) and 47% in the nonPOM fraction (stabilization, its depletion with increasing cultivation intensity suggests that the destruction of aggregates in these fields increased the vulnerability of this pool to microbial degradation.

    In a hypothetical case of severe accident in a PWR type VVER-440, a complex corium pool could be formed and fission products could be released. In order to study aerosols release in terms of mechanisms, kinetics, nature or quantity, and to better precise the source term of VVER-440, a series of experiments have been performed in the Colima facility and the test Colima CA-U3 has been successfully performed thanks to technological modifications to melt a prototypical corium at 2760 C degrees. Specific instrumentation has allowed us to follow the evolution of the corium melt and the release, transport and deposition of the fission products. The main conclusions are: -) there is a large release of Cr, Te, Sr, Pr and Rh (>95%w), -) there is a significant release of Fe (50%w), -) there is a small release of Ba, Ce, La, Nb, Nd and Y (<90%w), -) there is a very small release of U in proportion (<5%w) but it is one of the major released species in mass, and -) there is no release of Zr. The Colima experimental results are consistent with previous experiments on irradiated fuels except for Ba, Fe and U releases. (A.C.)

    Full Text Available A redução na qualidade pós-colheita do mamão deve-se em grande parte aos danos mecânicos, especialmente àqueles do tipo corte. O objetivo deste trabalho foi reproduzir este dano mecânico e avaliar os efeitos do número de cortes na qualidade e na fisiologia pós-colheita de mamões 'Golden'. Os cortes foram obtidos com o uso de uma lâmina de aço de 30 mm de comprimento e 5 mm de profundidade. Os tratamentos consistiram na reprodução de 1 a 4 cortes na região mediana dos frutos. Mamões sem cortes foram utilizados como controle. Após a reprodução dos danos, os frutos foram armazenados em câmara a 22ºC e 80-90% de UR por 10 dias. As análises de qualidade foram realizadas a cada dois dias, e as fisiológicas, diariamente. Os resultados demonstraram que a firmeza, o teor de sólidos solúveis e de ácido ascórbico, a atividade respiratória e a produção de etileno foram influenciados pelo número de cortes, de forma que a perda de qualidade dos frutos foi diretamente proporcional ao número de cortes.

    Full Text Available Resumo O objetivo deste trabalho foi quantificar os danos causados por um evento de granizo sobre uma lavoura comercial de soja. O evento de granizo ocorreu no município de Água Santa, no Estado do Rio Grande do Sul, durante o ano agrícola de 2013/2014. Foram realizadas avaliações da matéria seca do limbo foliar, pecíolo, legume e do índice de área foliar. Tais medições foram obtidas em data anterior e posterior ao evento de granizo que ocorreu no dia 08/02/2014. Com o auxílio de imagens de satélites e de radar foi possível identificar a intensidade do evento e a presença de granizo nas nuvens. Os danos provocados pelo granizo na cultura da soja foram: a redução da matéria seca nos limbos foliares (0,13 Mg ha−1, nos pecíolos (0,01 Mg ha−1 e nos legumes (0,002 Mg ha−1 das plantas da lavoura; o decréscimo no índice de área foliar de 7 a 34%; e a quebra do ápice de crescimento em 32% das plantas do experimento. Possivelmente, devido a esta redução na massa seca, houve diminuição na produtividade de soja da lavoura. As imagens de satélite e de radar podem ser ferramentas para auxiliar os extensionistas na determinação dos danos de granizo nas lavouras de soja.

    Avaliaram-se os efeitos de danos mecânicos ocasionados por cinco sistemas dosadores de sementes, em quatro culturas. Amostras das sementes foram coletadas antes e após passarem pelos sistemas dosadores e foram submetidas a testes de pureza, germinação e vigor. Não houve diferença entre os efeitos de danos mecânicos ocasionados pelos sistemas dosadores empregados nas sementes de milho. Para as sementes de feijão, menores efeitos foram verificados quando da utilização dos dosadores pneumático a vácuo e copo dosador. O sistema rotor acanalado causou menores danos às sementes de arroz e os sistemas disco  horizontal perfurado e copo dosador foram os que menos danificaram as sementes de soja. O sistema dosador pneumático a vácuo ocasionou o maior índice de dano mecânico nas sementes de soja.

    PALAVRAS-CHAVE: Semeadoras; distribuidores de sementes; rotor acanalado.

    Effects of mechanical damage caused by five seed metering systems were evaluated in four crops. Seed samples were collected before and after passing through the measuring systems and submitted to tests of purity, germination and vigor. There was no difference in the level of mechanical damage caused by the metering systems used for maize seeds. For common bean seeds, minor effects were verified when using the vacuum metering disk and the feed cup. The fluted feed system showed the best performance for rice seeds, and the horizontal perforated disk and feed cup systems exhibited the best results for soybean seeds. The vacuum metering disk system caused the highest level of mechanical damage to soybean seeds.

  8. Stratigraphic reconstruction of two debris avalanche deposits at Colima Volcano (Mexico): Insights into pre-failure conditions and climate influence

    Science.gov (United States)

    Roverato, M.; Capra, L.; Sulpizio, R.; Norini, G.

    2011-10-01

    Throughout its history, Colima Volcano has experienced numerous partial edifice collapses with associated emplacement of debris avalanche deposits of contrasting volume, morphology and texture. A detailed stratigraphic study in the south-eastern sector of the volcano allowed the recognition of two debris avalanche deposits, named San Marcos (> 28,000 cal yr BP, V = ~ 1.3 km 3) and Tonila (15,000-16,000 cal yr BP, V = ~ 1 km 3 ). This work sheds light on the pre-failure conditions of the volcano based primarily on a detailed textural study of debris avalanche deposits and their associated pyroclastic and volcaniclastic successions. Furthermore, we show how the climate at the time of the Tonila collapse influenced the failure mechanisms. The > 28,000 cal yr BP San Marcos collapse was promoted by edifice steep flanks and ongoing tectonic and volcanotectonic deformation, and was followed by a magmatic eruption that emplaced pyroclastic flow deposits. In contrast, the Tonila failure occurred just after the Last Glacial Maximum (22,000-18,000 cal BP) and, in addition to the typical debris avalanche textural characteristics (angular to sub-angular clasts, coarse matrix, jigsaw fit) it shows a hybrid facies characterized by debris avalanche blocks embedded in a finer, homogenous and partially cemented matrix, a texture more characteristic of debris flow deposits. The Tonila debris avalanche is directly overlain by a 7-m thick hydromagmatic pyroclastic succession. Massive debris flow deposits, often more than 10 m thick and containing large amounts of tree trunk logs, represent the top unit in the succession. Fluvial deposits also occur throughout all successions; these represent periods of highly localized stream reworking. All these lines of evidence point to the presence of water in the edifice prior to the Tonila failure, suggesting it may have been a weakening factor. The Tonila failure appears to represent an anomalous event related to the particular climatic

    Gymnodinium bloom events are of concern, since they produce toxins, which have unfavorable consequences to marine ecosystems, human health and the economy. This report describes the physico-chemical conditions that were present during the algal bloom event on May 2010 in Bahía Manzanillo and Bahía Santiago, Colima, Mexico. For this, seawater nutrient analysis, phytoplankton counts, identification, and toxicity tests were undertaken. Nutrients in seawater were determined using colorimetric techniques, the higher concentrations (8.88 microM DIN, 0.78 microM PO4 and 24.34 microM SiO2) were related with upwelling waters that promoted the algal bloom that began after registering the year lowest sea-surface temperature, favoring the rapid growth of G. catenatum (up to 1.02 x 10(7) cells/L). Phytoplankton counting was carried out using sedimentation chambers and cells enumerated on appropriated area. The bloom persisted in the bays for approximately two weeks and was associated with toxicity (determined with HPLC) in local oysters (1525.8 microg STXeq/100g), and in phytoplankton (10.9 pg STXeq/cells) samples. Strong variations in cell toxicity (1.4 to 10.9pg STXeq/cells), most likely reflected the availability of inorganic nutrients. The toxin profile of the phytoplankton samples consisted of 11 toxins and resembled those recorded for several strains of G. catenatum isolated from other coastal areas of Mexico.

    Full Text Available This study develops a novel computational framework to carry out probabilistic tsunami hazard assessment for the Pacific coast of Mexico. The new approach enables the consideration of stochastic tsunami source scenarios having variable fault geometry and heterogeneous slip that are constrained by an extensive database of rupture models for historical earthquakes around the world. The assessment focuses upon the 1995 Jalisco–Colima Earthquake Tsunami from a retrospective viewpoint. Numerous source scenarios of large subduction earthquakes are generated to assess the sensitivity and variability of tsunami inundation characteristics of the target region. Analyses of nine slip models along the Mexican Pacific coast are performed, and statistical characteristics of slips (e.g., coherent structures of slip spectra are estimated. The source variability allows exploring a wide range of tsunami scenarios for a moment magnitude (Mw 8 subduction earthquake in the Mexican Pacific region to conduct thorough sensitivity analyses and to quantify the tsunami height variability. The numerical results indicate a strong sensitivity of maximum tsunami height to major slip locations in the source and indicate major uncertainty at the first peak of tsunami waves.

    Full Text Available RESUMO A síndrome do desconforto respiratório agudo é um desafio para o intensivista. A característica principal desta doença aguda é o dano alveolar difuso, presente em cerca de metade dos pacientes com a síndrome. É claro que o suporte respiratório à síndrome do desconforto respiratório agudo tem melhorado gradualmente nas últimas décadas. É também evidente que todos estes procedimentos são benéficos, já que reduzem a lesão pulmonar e mantêm o paciente vivo. Isto deve ser interpretado como uma estratégia de ganho de tempo, até que o fator desencadeante ou de risco causal melhore, assim como a tempestade inflamatória diminua e o pulmão se cure. Por outro lado, todos - exceto dois tratamentos farmacológicos (bloqueadores neuromusculares e esteroides - são incapazes de melhorar o desfecho da síndrome do desconforto respiratório agudo. A hipótese de que os resultados farmacológicos negativos podem ser explicados pela heterogeneidade histológica da síndrome do desconforto respiratório agudo tem sido apoiada pelas recentes demonstrações de que a síndrome com dano alveolar difuso tem característica clínico-patológica específica. O dano alveolar difuso é um diagnóstico patológico, e a biópsia pulmonar a céu aberto (a técnica mais comum para obtenção de tecido pulmonar tem efeitos colaterais graves, sendo necessário que se desenvolvam biomarcadores substitutos para o dano alveolar difuso. O objetivo desta revisão é discutir três tópicos relacionados à síndrome do desconforto respiratório agudo: o relacionamento entre a síndrome do desconforto respiratório agudo e o dano alveolar difuso; como o dano alveolar difuso pode ser representado no quadro clínico; e como o enriquecimento pode melhorar os resultados de estudos clínicos farmacológicos realizados com pacientes com a síndrome e com dano alveolar difuso.

    Based on a survey data collected from 150 farming households in Dano district of western Showa of Ethiopia, this paper analyzes determinants of smallholders' choice for market oriented indigenous Horo cattle production and tries to suggest policy alternatives for sustainable use of animal genetic resource in the study area. Descriptive statistics and binary logistic model were employed to analyze the data. Eight explanatory variables including age of the household head, size of the grazing land, total size of cultivated land, farmer's experience in indigenous cattle production, farmer's attitude towards productivity of local breed, off-farm income, fattening practice, and availability of information and training of the head of the household regarding conservation, management and sustainable use indigenous cattle were found to be statistically significant variables to explain farmers' choice for market oriented indigenous cattle production activities. Besides, possible policy implications were made in order to improve conservation, management and sustainable use of market oriented indigenous cattle genetic resources.

    2013-12-01

    Volcán de Colima has a historical record with major explosive eruptions occurring every ~100 years (1606, 1690, 1818, and 1913) followed by intra-Plinian effusive activity. The 1818 and 1913 Plinian eruptions erupted andesitic magmas (Pl > Opx > Cpx >> Hbl + Fe-Ti oxides + Ap and rare resorbed Ol) with homogeneous bulk compositions (1913; 58.3 × 0.5 wt.% SiO2, 1818; 58.9 × 0.2 wt.% SiO2; Saucedo et al., 2010). Instead, intra-Plinian magmas are devoid of hornblende and have compositions of 59-61 wt. % in silica (Savov et al., 2008). Pre-eruptive temperatures of oxide Fe-Ti pairs in 1818 and 1913 products yielded temperatures of 830×20°C colder than intra-Plinian magmas usually >970°C (Luhr et al., 2002) depending on the mineral phase analyzed. Amphibole in 1818 and 1913 products consists of two populations: a) large xenocrysts, with plag-px-Fe-Ti oxide rims with equilibrium pressures and temperatures of 380 MPa and 950 °C (Ridolfi et al., 2010), and b) microphenocryst with equilibrium pressures and temperatures of 190-280 MPa and 870-910 °C, respectively. Some phenocrysts in the 1818 magma have a high pressure core overgrowth by a low pressure rim. In order to understand the storage conditions of Colima explosive magmas we carried out a set of hydrothermal experiments with a 1818 pumice sample. Experiments were water oversaturated and close to the oxygen fugacity of the NNO buffer. Experiments show that amphibole is stable at pressures greater than 75 MPa at 850°C, and greater than 100 MPa at 925°C. For the same range of temperature, plagioclase is stable at pressures below ~210 MPa and 100 MPa, respectively. Experimental plagioclase and experimental glass were analyzed and compared to those from the natural sample, yielding an approximate storage pressure of 210 MPa. This pressure is confirmed by the chemical equilibrium of microphenocrystic amphibole of the natural sample. Given the nearly equivalent composition of the most recent Plinain magmas is

    Full Text Available Gymnodinium bloom events are of concern, since they produce toxins, which have unfavorable consequences to marine ecosystems, human health and the economy. This report describes the physico-chemical conditions that were present during the algal bloom event on May 2010 in Bahía Manzanillo and Bahía Santiago, Colima, Mexico. For this, seawater nutrient analysis, phytoplankton counts, identification, and toxicity tests were undertaken. Nutrients in seawater were determined using colorimetric techniques, the higher concentrations (8.88μM DIN, 0.78μM PO4 and 24.34μM SiO2 were related with upwelling waters that promoted the algal bloom that began after registering the year lowest sea-surface temperature, favoring the rapid growth of G. catenatum (up to 1.02 x10(7cells/L. Phytoplankton counting was carried out using sedimentation chambers and cells enumerated on appropriated area. The bloom persisted in the bays for approximately two weeks and was associated with toxicity (determined with HPLC in local oysters (1525.8μg STXeq/100g, and in phytoplankton (10.9pg STXeq/cells samples. Strong variations in cell toxicity (1.4 to 10.9pg STXeq/cells, most likely reflected the availability of inorganic nutrients. The toxin profile of the phytoplankton samples consisted of 11 toxins and resembled those recorded for several strains of G. catenatum isolated from other coastal areas of Mexico.La proliferación de Gymnodinium son motivo de preocupación, debido a que en algunas circunstancias producen toxinas, que tienen consecuencias desfavorables para los ecosistemas marinos, la salud humana y la economía.

    Landeg, O.

    Contemporary disaster risk management requires the analysis of vulnerability and hazard exposure, which is imperative at Volcan de Colima (VdC), Mexico, due to the predicted, large-magnitude eruption forecast to occur before 2025. The methods used to gauge social vulnerability included the development and application of proxies to census records, the undertaking of a building vulnerability survey and the spatial mapping of civil and emergency infrastructure. Hazard exposure was assessed using primary modelling of laharic events and the digitalisation of secondary data sources detailing the modelled extent of pyroclastic flows and tephra deposition associated with a large-magnitude (VEI 5) eruption at VdC. The undertaking and analysis of a risk perception survey of the population enabled an understanding of the cognitive behaviour of residents towards the volcanic risk. In comparison to the published hazard map, the GIS analysis highlighted an underestimation of lahar hazard on the western flank of VdC and the regional tephra hazard. Vulnerability analysis identified three communities where social deprivation is relatively high, and those with significant elderly and transient populations near the volcano. Furthermore, recognition of the possibility of an eruption in the near future was found to be low across the study region. These results also contributed to the analysis of emergency management procedures and the preparedness of the regional authorities. This multidisciplinary research programme demonstrates the success of applying a GIS platform to varied integrative spatial and temporal analysis. Furthermore, ascertaining the impact of future activity at VdC upon its surrounding populations permits the evaluation of emergency preparedness and disaster risk reduction strategies.

    Full Text Available The use of soybean cultivars resistant to insects and diseases reduces the application of pesticides, decreasing production costs and promoting a sustainable agriculture. The damage of stink bugs and defoliators and the severity of powdery mildew (Microsphaera diffusa in soybean of three maturity groups were evaluated under field conditions, at Tarumã and Ribeirão Preto, State of São Paulo, Brazil. Three experiments, one for each group, were carried out in the 1999/2000 and 2000/2001 growing seasons. In 1999/2000, the disease occurred in Tarumã; in that year, infestation of chrysomelids (Cerotoma sp. and Colaspis sp. was observed in Ribeirão Preto. Low infestations of stink bugs occurred in both years and locations, but in Tarumã, at the stage of plant maturation, the insect population exceeded the economic injury level. The severity of powdery mildew was evaluated using a scale varying from 1 (no symptom to 5 (more than 50% of leaves with symptoms. Chrysomelid injuries were estimated by the percentage of leaf area removed, and stink bug damage was evaluated by the percentage of leaf retention (LRP and yield. Within the early maturity group (110 days, IAC 94-2675 showed good yield levels, low LRP, and resistance to powdery mildew. In the genotypes of the 120-day maturity group, IAC 94-5, IAC 94-1172, IAC 94-1017, IAC 94-133, and IAC 94-745 presented good yield; the last two behaved as resistant to the disease.

    On October 16, 1955, at 10:45 a.m. (local time), after three days of intense rain (140 mm) that was twice the monthly average precipitation, a devastating flood surge formed a volcaniclastic debris flow on the eastern slopes of Nevado de Colima Volcano. Nearly simultaneous flood surges formed in the Arroyo Seco, Los Platanos, and Dos Volcanes ravines that coalesced with the larger flow in the Atenquique ravine. At each confluence with a tributary, the flow was diluted. The texture and structure of the preserved 1955 deposits near high water marks indicate that the downstream flow was mainly in the lower range of debris flow concentration (60% sediment concentration by weight). Downstream the tributaries, the flood encountered a ˜ 0.06 × 10 6 m 3 water reservoir that failed, significantly increasing the surge volume. Additional entrained sediment also increased the flow volume. Downstream, the flood wave reached the town of Atenquique as an 8-9 m catastrophic wave causing the death of more than 23 people, the partial destruction of the town, and losses of ˜ 13,000,000 pesos (˜ 1 million US dollars today) to a paper mill and company facilities. According to eyewitness accounts the flood wave had a peak discharge that lasted ca. 10 to 15 minutes at Atenquique. Deposits at the site and the high-water marks observed from photographs of the town's church indicate that sediment concentration was ca. 60 wt.%. The flood continued for about 1 km to its junction with the Tuxpan River where it was diluted by mixing with normal flood flow. The deposits covered an area of ˜ 1.2 km 2 and had a minimum volume of ˜ 3.2 × 10 6 m 3. The main deposit consists of a single unit, averaging 4 m in thickness, with weak textural variations that suggest surging within the flood wave. The deposit is heterolithologic and consists of boulders set in a matrix of sand-size sediment, with polymodal or bimodal distributions and normal grading varying with distance from source.

    The Colima volcano, during the years 2015-2017, presented an important effusive and explosive activity, which began in January 2015 with the growth of a dome that was destroyed by explosions, forming pyroclastic flows reaching distances of up to 2 km by the north and south flanks of the volcano. In May a new dome was extruded, forming three thick lava flows along the northern and southern slopes; the extruded volume was approximately 6 million cubic meters, with a rate in 52 days of 1.3 m3/sec. On July 11 merapi flows were formed it flowed through by the ravines of Montegrande and San Antonio, on the south and southwest flank, reaching distances of 10.4 km. The following days the activity had decreased substantially, leaving a crater of 60 m of depth and 270 m of diameter. In February 2016, a small dome occupied the central part of the main crater, and it was until September that an episode of volcanic tremor began, that was associated with its rapid growth, which in 48 hours filled the crater and formed a lava flow that descended by the south slope. By October 2, 2.3 million m3 of lava were extruded, which caused a deflation of the dome. In October 7, the volcano emitted a great amount of gases and steam of water that formed an acid rain that affected forests and crops of the south and southwest slope, causing losses by 1 million dollars. In November, a series of explosions occurred that destroyed two thirds of the dome. In January 2017, the explosive activity increased and again destroyed the dome. Five events were recorded that reached between 3 km and 4 km of height on the top of the volcano, the dispersion of the ash generally went to the northeast, reaching distances of up to 200 km. Currently the volcano is sustaining reduced seismic and fumarole activity. In 2005, 2015 and 2017, the geochemical analysis of major elements such as SiO2 from the ash emitted by the volcano showed an increase from 54.51% to 60.05% and 60.24%, respectively, which was associated

    Coral reef ecosystems are under stress of different origins, from factors including sedimentation, fragmentation, overfishing, and tourism, depending on their geographical location, depth, and proximity to recreation areas. In this study of Juluapan Lagoon, we examined the relationship between various water-quality attributes and the status indicators of the coral community at La Boquita reef. During 2011 (12 months of sampling), six monitoring stations in the Juluapan lagoon were established in order to observe the gradient of the distribution of the physicochemical parameters: three stations on the upper part, or BI, (S4 to S6) and three more in the lower part, or BII, (S1 to S3). A control station (CS) was located in the coral reef close to the lagoon channel, and where dissolved inorganic nutrients and cellular carbon content were determined. Additionally, we considered the monitoring of three of the eight largest coral structures/headlands of this community: the first was the station closest to the channel communicating with Juluapan lagoon (C1), the second was in the intermediate region with respect to that lagoon (C2), and the third was farthest from the channel (C3). Three line intercept transects (LIT) 30 m in length and perpendicular to the coast provenance were established in each station, and the parameters indicative of the status of corals were evaluated in an area of 60 m2 on each transect (180 m2 by the station). Turbidity, evidence of fishing, signs of settling, algal coverage, abundance of fish, rate of sediment, and coral health records (as for CoralWach chart) were determined in situ and from digital photographs and videos. Considering various community status indicators used in the reef area, we could recognize a state of general deterioration, which was reflected in the loss of 17 % of coral coverage. The main anthropogenic disturbances in adjacent areas to La Boquita reef included wastewater discharges into the lagoon, tourist developments in

Consideradas chaves para a produção de citros, torna-se necessário o seu monitoramento, visando a evitar os danos diretos. O experimento teve como objetivos conhecer a variação populacional de Anastrepha fraterculus e a relação de sua população com danos em pomares orgânicos de Citrus sinensis, cultivar Céu e de C. sinensis x Citrus reticulata tangor 'Murcott'. Os dados foram coletados em 2003 e 2004 durante o período de maturação dos frutos, na região do vale do Caí, RS, Brasil. O número de moscas-das-frutas foi registrado, semanalmente, por meio de armadilhas McPhail, contendo suco de uva, a 25%. Danos aos frutos foram determinados pela razão entre frutos sadios e frutos danificados pela mosca. Registros meteorológicos de temperatura, umidade relativa e precipitação pluviométrica foram obtidos, em estação meteorológica distante 30 km das áreas experimentais. Verificou-se que, em condições ideais de precipitação pluvial, maiores foram as populações de A. fraterculus, espécie predominante na região. A população estimada capaz de causar danos aos frutos variou de acordo com o cultivar, sendo a laranjeira 'Céu' a mais susceptível. Os maiores picos populacionais ocorrem na fase de mudança de coloração dos frutos. Porém, na fase de maturação, as moscas causaram os maiores danos, dada a intolerância dos frutos ao ataque. Conclui-se que a infestação dos frutos de citros por A. fraterculus está relacionada com espécie e cultivar e com fatores climáticos, principalmente com a precipitação pluvial. O monitoramento constante da população de mosca-das-frutas é importante na determinação da infestação na colheita.

    In this work the evolution is described that undergoes the factor of damage in a well during its productive stage, which is identifiable from the diminution in the characteristics of its production. It is mentioned that during the productive stage of wells, its declination is, in many occasions, synonymous of the damage presence. Traditionally, the damage effect is determined from the equations for analysis of the transitory tests of pressure. Nevertheless, the execution of this type of tests requires relatively long periods of time to obtain the stabilization of the well and of significant costs. By the previous facts the development of techniques to determine the damage from production tests was initiated. In this article is presented the curve-type of geothermal inflow affected by the damage, from which the value of this one in a geothermal well for the time in which its test of production is realized can be determined. A methodology is proposed to determine the damage effect in the well using the proposed curve-type and its applicability with examples of test measurements of well discharge is demonstrated in Mexican geothermal fields. From the conducted analyses it is found that the numerical value of the damage determined in selected wells increases based on the time of exploitation, which indicates a deterioration of its productive characteristics. The previous statements aid to constitute a technical endorsement for the decision making, on the pertinent actions that can be executed in the well.

    Pyroclastic density currents (PDCs) represent one of the most dangerous phenomena occurring in explosive volcanic eruptions, and any advance in the physical understanding of their transport and sedimentation processes can contribute to improving their hazard assessment. The 10-11 July 2015 eruption at Volcán de Colima provided a unique opportunity to better understand the internal behaviour of PDCs based on seismic monitoring data. On 10 July 2015, the summit dome collapsed, producing concentrated PDCs that filled the main channel of the Montegrande ravine. A lahar monitoring station installed 6 km from the volcano summit recorded a PDC before being completely destroyed. Real-time data acquisition from a camcorder and a geophone that were part of the station, along with field observations and grain-size data of the pyroclastic deposits, are used here to interpret the internal flow structure and time-variant transport dynamics of low-volume, valley-confined concentrated PDCs. The PDC that reached the monitoring station moved at a velocity of 7 m/s and filled a 12-m-deep channel. The outcrops show massive, block-and-ash flow deposits with trains of coarse clasts in the middle and towards the top of the depositional units. The seismic record gathered with the geophone was analysed for the time window when the flow travelled past the sensor. The geophone record was also compared with the recordings of a broadband seismic station located nearby. Two main frequency ranges were recognised which could be correlated with the basal frictional forces exerted by the flow on the channel bed (10-20 Hz) and a collisional regime (20-40 Hz) interpreted to be associated with a clast segregation process (i.e. kinematic squeezing). This latter regime promoted the upward migration of large blocks, which subsequently deviated towards the margin of the flow where they interacted with the sidewall of the main channel. The energy calculated for both seismic components shows that the

    Full Text Available O diabetes é um distúrbio complexo e heterogêneo caracterizado por hiperglicemia resultante de defeitos na secreção e ação da insulina. Tem sido reconhecido que, além do comprometimento de órgãos como rins, olhos, fígado e coração, o sistema nervoso central é suscetível aos efeitos deletérios da hiperglicemia em longo prazo. A encefalopatia diabética representa uma das complicações do diabetes, na qual os danos são caracterizados por alterações do funcionamento cognitivo, modificações estruturais e neurofisiológicas no cérebro. Existe uma associação bem reconhecida entre a depressão e o diabetes, uma vez que a prevalência de depressão é maior na população diabética comparada com a população geral. Porém, os mecanismos atribuídos a essa relação ainda estão em fase de investigação. O estresse oxidativo desempenha um papel importante nas complicações do diabetes e pode ser um mecanismo biológico envolvido na relação entre a depressão e o diabetes, relacionado à encefalopatia diabética. Neste artigo de revisão, apresentamos uma visão geral dos principais conceitos relacionados ao assunto, bem como dos dados clínicos e experimentais que suportam a relação entre o dano oxidativo no cérebro e a depressão relacionada com encefalopatia diabética.   Diabetes is a complex and heterogeneous disorder characterized by hyperglycemia resulting from defects in the secretion and action of insulin. It has been recognized that, in addition to the involvement of organs such as kidney, eye, liver, and heart, the central nervous system is susceptible to the deleterious effects of hyperglycemia in the long term. Diabetic encephalopathy is one of the complications of diabetes, in which the damage is characterized by changes in cognitive functioning, structural and neurophysiologic changes in the brain. There is a well-known association between depression and diabetes, since the prevalence of depression is

    2016-06-01

    This study investigates the impacts of land use change on water resources in the Dano catchment, Burkina Faso, using a physically based hydrological simulation model and land use scenarios. Land use dynamic in the catchment was assessed through the analysis of four land use maps corresponding to the land use status in 1990, 2000, 2007, and 2013. A reclassification procedure levels out differences between the classification schemes of the four maps. The land use maps were used to build five land use scenarios corresponding to different levels of land use change in the catchment. Water balance was simulated by applying the Water flow and balance Simulation Model (WaSiM) using observed discharge, soil moisture, and groundwater level for model calibration and validation. Model statistical quality measures (R2, NSE and KGE) achieved during calibration and validation ranged between 0.6 and 0.9 for total discharge, soil moisture, and groundwater level, indicating a good agreement between observed and simulated variables. After a successful multivariate validation the model was applied to the land use scenarios. The land use assessment exhibited a decrease of savannah at an annual rate of 2% since 1990. Conversely, cropland and urban areas have increased. Since urban areas occupy only 3% of the catchment it can be assumed that savannah was mainly converted to cropland. The conversion rate of savannah was lower than the annual population growth of 3%. A clear increase in total discharge (+17%) and decrease in evapotranspiration (-5%) was observed following land use change in the catchment. A strong relationship was established between savannah degradation, cropland expansion, discharge increase and reduction of evapotranspiration. The increase in total discharge is related to high peak flow, suggesting (i) an increase in water resources that are not available for plant growth and human consumption and (ii) an alteration of flood risk for both the population within and

    Full Text Available The quality of the raw material defines the industrial potential production. The harvest of raw sugarcane promoted a favorable environment for the increase of Mahanarva fimbriolata (Stål, 1854 pest that affects the plant development. This research was undertaken to evaluate the effects of M. fimbriolata on sugarcane quality and fermentation process. For the technological analysis, four damage levels and two evaluation periods were evaluated, while four fermentation cycles and two evaluation periods were tested for microbiological analysis, with three replications. The determined parameters were Brix (soluble solids, Pol (apparent sucrose, Purity, reducing sugars (RS, total reducing sugars (TRS, Total Acidity, pH and Total Phenolic Compounds in juice. In the fermentation process cellular viability analysis, yeast sprout and bacterial concentration were carried out. The wine was submitted to alcohol content, TRRS (total residual reducing sugars and fermentation efficiency. The treatment with 60% of damage steams exhibited the lowest averages of Brix, Pol, Purity and TRS of the juice. An increase of the RS% of the juice and content of total phenolic compounds was observed. The cellular and sprouts viability were reduced with the increase in the damages caused by M. fimbriolata. The fermentation process exhibited larger quantities of contaminators. With the damages, the wine TRRS quantity was superior and, consequently there was a decrease of the alcoholic content and fermentation efficiency. The damages caused by M. fimbriolata affected the quality of the raw material, compromising the fermentative process, and increase the production of phenolic compounds and contaminators.A qualidade da matéria-prima define o potencial de produção da indústria. A colheita de cana sem queima proporcionou um ambiente favorável ao aumento da infestação da Mahanarva fimbriolata (Stål, 1854, que suga a planta e afeta seu desenvolvimento. Avaliaram-se os danos

    Full Text Available O presente artigo aborda a temática das políticas brasileiras referentes às drogas, com o objetivo de resgatar o histórico da estratégia de redução de danos (RD no Brasil. A partir de pesquisa bibliográfica em sítios de domínio público e em bases de dados disponíveis na internet, rastreamos o surgimento da estratégia de redução de danos no País, cujo marco foi a epidemia da AIDS da década de 80 e as políticas que a antecederam. Os dados coletados suscitam reflexões sobre os desafios contemporâneos enfrentados pelo emprego da estratégia de RD no campo do uso e do abuso de drogas lícitas e ilícitas, como álcool e crack, o preconceito vigente em relação ao usuário de drogas e a exigência de intervenções intersetoriais no enfrentamento do fenômeno do consumo de drogas. Além disso, mantém-se até os dias atuais o descompasso histórico entre as políticas sobre drogas oriundas do campo da segurança e aquelas provindas da saúde pública, com predominância daquelas de cunho proibicionista. Enquanto isso, a produção de drogas lícitas e ilícitas se diversifica, gerando a necessidade de tornar variadas as ações de redução de danos.

    The July 2015 block-and-ash flow (BAF) events represent the first documented series of large-volume and long-runout BAFs generated from sustained dome collapses at Volcán de Colima. This eruption is particularly exceptional at this volcano due to (1) the large volume of BAF material emplaced (0.0077 ± 0.001 km3), (2) the long runout reached by the associated BAFs (max. 10 km), and (3) the short period ( 18 h) over which two main long-sustained dome collapse events occurred (on 10 and 11 July, respectively). Stratigraphy and sedimentology of the 2015 BAF deposits exposed in the southern flank of the volcano based on lithofacies description, grain size measurements and clast componentry allowed the recognition of three main deposit facies (i.e., valley-confined, overbank and ash-cloud surge deposits). Correlations and lithofacies variations inside three main flow units from both the valley-confined and overbank deposits left from the emplacement of the second series of BAFs on 11 July provide detailed information about: (1) the distribution, volumes and sedimentological characteristics of the different units; (2) flow parameters (i.e., velocity and dynamic pressure) and mobility metrics as inferred from associated deposits; and (3) changes in the dynamics of the different flows and their material during emplacement. These data were coupled with geomorphic analyses to assess the role of the topography in controlling the behaviour and impacts of the successive BAF pulses on the volcano flanks. Finally, these findings are used to propose a conceptual model for transport and deposition mechanisms of the July 2015 BAFs at Volcán de Colima. In this model, deposition occurs by rapid stepwise aggradation of successive BAF pulses. Flow confinement in a narrow and sinuous channel enhance the mobility and runout of individual channelized BAF pulses. When these conditions occur, the progressive valley infilling from successive sustained dome-collapse events promote the

    Full Text Available A abordagem da responsabilidade do fornecedor e do Estado, sob a ótica dos danos causados ao consumidor na fase pós-consumo, é o que se abordará no presente artigo. Analisar-se-ão os princípios centrais aplicados ao Direito Ambiental e do Consumidor a fim de construir responsabilidade específica tanto para o fornecedor quanto para o Estado pelos danos decorrentes do consumo de produtos que tenham descartes. Questiona-se um novo modelo de responsabilidade no âmbito do Código de Defesa do Consumidor, contextualizando-se o problema na sociedade contemporânea com o objetivo de estudar as maneiras de resguardar, integralmente, as lesões ao consumidor em virtude da falta de gestão ambiental de produtos que, após serem consumidos, poderão ser destinados ao lixo comum ou não, causando degradação ao meio ambiente e consequentemente ao homem/consumidor, apontando-se assim possíveis proposições para dirimir o problema.

    parent’s children are agressivity, hasty, anxious and concentrating problems in the subjects. In addition, they get all kind of sickness and pains like headaches, stomackaches and even diabet. All of this, is a result of the insecurity feeling before the troubled separation process. Finally, thinking about all the problems involved in the divorce, and mainly that the mensal contribution is not enough to cover the children and the teens emotional treatments, it has been requisiting a indenization to compensate the negative effects that some separations can cause to divorced parent’s descendants. This can be done through a repair like moral damage.A personalidade em formação pode sofrer danos irreversíveis ou de difícil reversão ante fatos como as separações conjugais traumáticas. Elas causam aos filhos menores de casais que passam por isto uma enorme amargura. Estas apresentam geralmente, um quadro de somatização, manifestações do inconsciente, quadros clínicos, dificuldades de socialização. A pensão alimentícia, atualmente único remédio jurídico, não tem como proporcionar o conforto emocional e a segurança que só o convívio com os pais pode transmitir aos filhos. São vários os casos encontrados na psicanálise, motivados por eventos marcantes no período infanto-juvenil. Muitos demandam tratamento especializado. Verifica-se que os dois primeiros anos após a separação são os mais difíceis e as crianças em fase escolar, a partir de 6 a 7 anos, são as que apresentam maiores dificuldades de relacionamento. Os sintomas apresentados são a impulsividade, a agressividade e dificuldades na escola. Como a pensão alimentícia não tem o condão de abranger todos estes particulares, visualiza-se a possibilidade de se compensar os efeitos negativos que algumas separações conjugais trazem aos filhos, mediante o pagamento de indenização a título de danos morais.

    Directory of Open Access Journals (Sweden)

    Márcia Rodrigues Bertoldi

    2015-08-01

    Full Text Available Resumo: O princípio da responsabilidade impõe um imperativo moral, no sentido de que se deve agir de modo que os direitos estabelecidos sejam compatíveis com a permanência de uma autêntica vida humana na Terra. É com a intenção de atar firmemente a efetiva responsabilização pelo dano ambiental ao imperativo moral em seu viés preventivo e repressivo que este trabalho se põe em marcha. Os modos de vida humanos individuais e coletivos das sociedades ocidentais evoluem no sentido de uma progressiva deterioração do meio ambiente. É a relação da subjetividade com sua exterioridade que se encontra comprometida. Se não houver uma rearticulação dos três registros fundamentais da ecologia – subjetivo, social e ambiental –, podemos, infelizmente, pressagiar a escalada de todos os perigos que envolvem a sociedade atual. Em lugar da relação harmônica e sustentável com o meio ambiente, as sociedades de consumo introduziram a ideia da subjetividade que constrói o mundo que a circunda. A relação do sujeito com o mundo no qual se encontra deve ser sua principal preocupação. Para isso, torna-se imprescindível um envolvimento com a efetiva proteção do meio ambiente, caso se queira manter a vida na Terra para as presentes e futuras gerações. A implementação de uma hermenêutica jurídica eminentemente ambiental é o caminho jurídico para a efetiva proteção do chamado bem ambiental, considerando-se as especificidades do bem em comento. Na esteira dessa hermenêutica, o dano moral ambiental objetivo encontra respaldo, e o seu agente pode ser responsabilizado. Palavras-chave: Hermenêutica ambiental. Risco ambiental. Dano moral ambiental objetivo.

    2015-04-01

    Full Text Available INTRODUÇÃO: os músculoesqueléticos são tecidos dinâmicos que podem alterar suas características fenotípicas proporcionando melhor adaptação funcional com estímulos variados. A L-tiroxina é um hormônio produzido pela glândula tireoide e tem sido utilizada como modelo experimental para estimulação de estresse oxidativo no músculo esquelético. A coenzima Q10 é uma provitamina lipossolúvel sintetizada endogenamente e naturalmente encontrada em alimentos como carne vermelha, peixes, cereais, brócolis e espinafre. Apresenta propriedade antioxidante e tem potencial no tratamento de doenças degenerativas e neuromusculares. OBJETIVO: avaliar o efeito protetor da coenzima Q10 no músculo sóleo de ratos frente aos danos oxidativos provocados pela L-tiroxina. MÉTODOS: os ratos foram distribuídos em quatro grupos de seis animais cada: Grupo 1 controle; Grupo 2 coenzima Q10; Grupo 3 L-tiroxina e Grupo 4 coenzima Q10 e L-tiroxina. Após a eutanásia, o sangue dos animais foi colhido e foi analisada a atividade sérica das enzimas creatina quinase CK e aspartato aminotransferase AST. No homogenato do músculo sóleo foram avaliados fatores relacionados ao estresse oxidativo. RESULTADOS: a coenzima Q10 protegeu o músculo sóleo dos danos provocados pela L-tiroxina e favoreceu a manutenção da atividade das enzimas antioxidantes glutationa redutase e glutationa peroxidase, da concentração de glutationa reduzida e oxidada, além de evitar a lipoperoxidação. CONCLUSÃO: os resultados indicam que a coenzima Q10 protege o músculo sóleo de ratos dos danos oxidativos provocados pela L-tiroxina.

    Full Text Available O objetivo deste trabalho foi avaliar a utilização do teste Lercafé, para estimar a germinação e caracterizar diferentes tipos de danos em sementes de cafeeiro. Utilizaram-se sementes de cafeeiro arábica cultivar Catuaí IAC 44, submetidas aos seguintes tratamentos: sementes sem dano, sementes com dano por secagem a 40 e 60ºC, e sementes brocadas. As sementes foram avaliadas pelos testes de germinação e Lercafé. Em relação aos dois tipos de danos, os resultados de germinação, estimada pelo Lercafé, apresentaram alta correlação com os obtidos pelo teste de germinação. O dano por secagem à alta temperatura caracterizou-se pelo aparecimento de manchas esverdeadas espalhadas, que atingiram parcial ou totalmente o endosperma da semente. O dano por broca caracterizou-se por uma depressão circundada por um anel de coloração verde. O teste Lercafé é eficiente para estimar a germinação e caracterizar os danos por secagem à alta temperatura e os causados por broca, em sementes de cafeeiro.The objective of this work was to evaluate the use of the Lercafé test for estimating the germination and characterizing different types of injuries in coffee seeds. Seeds of arabica coffee cultivar Catuaí IAC 44 were submitted to the following treatments: nondamaged seeds, heat damage (at 40 and 60ºC, and bug damage. Seeds were assessed by the tests of germination and Lercafé. The germination results estimated by Lercafé test had high correlation with the results from the germination test for the two types of injuries. The heat damage, by drying seeds at high temperatures, was characterized by scattered green stains, partially or totally covering the seed endosperm. A sunken lesion surrounded by a green ring characterized the damage by coffee berry borer. Lercafé test is efficient to estimate the germination and to characterize the injuries by heat and coffee berry borer, in coffee seeds.

    Full Text Available In spite of the advances in transmission electronic microscopy (TEM, there are few studies presenting a systematic description of the canine spermatozoa and they are only focused on sperm cell heads. The goal of the present study was to describe ultrastructural appearance of canine fresh and frozen-thawed spermatozoa, focusing on damages induced by freezing-thawing in different sperm regions. Ten ejaculates from five proven stud dogs (two ejaculates/dog were collected, evaluated, extended in Tris-egg yolk-glycerol, frozen and stored in liquid nitrogen, and thawed six weeks later.  Samples were evaluated for progressive motility, morphology, and for ultrastructural analysis by TEM. Concerning to TEM, the most striking differences between fresh and frozen-thawed samples were observed over the mid-piece since the fresh spermatozoa showed a well preserved mid-piece. However, the frozen-thawed spermatozoa mid-piece showed signs of damage such as mitochondrial vacuolization. In conclusion, freezing-thawing processes using a Tris-egg yolk extender induce ultrastructural damages in head and mid-piece of canine sperm, affecting the mitochondrial ultrastructure besides.

    This study focuses on the observation of a creeping phenomenon that produces subsidence of the Zapotlan basin and ground fracturing in correspondence of the Ciudad Guzmàn (Jalisco - Mexico). The September 21, 2012, the Ciudad Guzmàn has been struck by a phenomenon of ground fracturing of about 1.5 km of length. This event caused the deformation of the roads and the damage of 30 houses, of which eight have been declared uninhabitable. The alignment of fractures is coincident with the escarpments produced in September 19, 1985, in the Ciudad Guzman urban area, when a strong earthquake, magnitude 8.1, struck the Mexican area, causing the deaths of at least 10,000 people and serious damage in Mexico City. In Ciudad Guzmán, about 60% of the buildings were destroyed, with about 50 loss of life. The city is located in the Zapotlan basin (northern Colima graben), a wide tectonic depression where the depth of the infilling sediments is about 1 km. This subsidence cannot be measured outside the urbanized area, but it can be considered as a deformation mechanism of the central part of the basin. In order to detect and mapping the spatio-temporal features of the processes that led to this event, we applied InSAR multi-temporal techniques to analyze a dataset of ENVISAT satellite SAR images, acquired in a time span between 2003-2010. InSAR techniques detect a subsidence of the north-western part of Ciudad Guzmàn of about 15 mm/yr in the time interval 2003-2010. The displacement occurred in September 21, 2012, was detected using two RadarSAT2 acquisitions (2012-03-22 and 2013-03-17). The explanation of surface movements based on interferometric results, ground data and geological field observations, allowed confirming surface effect due to the overexploitation of the aquifers and highlights a subsidence due to anthropogenic causes coupled to buried tectonic structures.

    Dome building activity is common at many volcanoes and due to the gravitational instability, a dome represents one of the most hazardous volcanic phenomena. Shallow volcanic processes as well as rheological and structural changes of the dome affecting the fluid transport have been linked to transitions in eruptive activity. Also, hydrothermal alteration may affect the structural integrity of the dome, increasing the potential for collapse. However, mapping the deformation and details of fluid escape at the summit of steep sloped volcanoes and integrating these with other types of data is challenging due to difficult access and poor coverage. Here we present for the first time the near-vertical and near-horizontal surface deformation field of a quiescent summit dome and the relationships with degassing and topographic patterns. Our results are derived from high resolution satellite radar interferometry (InSAR) time series based on a year of TerraSAR-X SpotLight acquisitions and Structure from Motion (SfM) processing of overflight infrared data at Volcán de Colima, Mexico. The identified deformation is dominated by localized heterogeneous subsidence of the summit dome exceeding rates of 15 cm/yr, and strongly decreasing over the year 2012, up to the renewal of explosive and extrusive activity in early 2013. We tentatively attribute the deformation to the degassing, cooling and contraction of the dome and shallow conduit material. We also find that the results strongly differ depending on the chosen InSAR time series method, which potentially overprints the true physical complexities of small scale, shallow deformation processes. The combined interpretation of the deformation and infrared data reveals a complex spatial relationship between the degassing pathways and the deformation. While we observe no deformation across the crater rim fumaroles, discontinuities in the deformation field are more commonly observed around the dome rim fumaroles and occasionally on the

Foram realizados cinco experimentos em ambiente controlado, em 2006, 2007 e 2008. Os fatores avaliados foram: genótipos, aclimatação (com; sem, intensidades de geada, estádios de desenvolvimento de plantas, regimes de aclimatação e regimes de geada. As variáveis avaliadas foram: queima de folhas, massa de matéria seca, estatura de plantas, duração de subperíodo, componentes de rendimento e rendimento de grãos. A aclimatação ao frio, antes da geada, resultou em menor queima de folhas e maior massa de matéria seca, em comparação a plantas não aclimatadas. As geadas foram prejudiciais a partir de -6°C no início do ciclo de desenvolvimento, principalmente em plantas não aclimatadas, e a partir de -4ºC na floração, com redução do número de síliquas e do número de grãos por síliqua. A aclimatação após as geadas não contribuiu para a tolerância da canola a esse evento. Geadas consecutivas não acarretaram maior prejuízo à canola. A aclimatação de plantas de canola antes da geada reduz os danos, principalmente quando a geada ocorre no início do desenvolvimento das plantas.The objective of this work was to evaluate the influence of cold acclimatization on frost damage at different phenological stages of canola genotypes. Five experiments were carried out under controlled conditions, in 2006, 2007, and 2008.

    Full Text Available El trabajo analiza la geomorfología de dunas costeras longitudinales del Istmo de Médanos, costa noroccidental de Venezuela. La metodología consistió en consultas bibliográficas, cartográficas, fotogramétricas y satelitales, trabajos de campo y análisis sedimentológico. Los resultados indican que estas dunas están compuestas por arenas de grano fino en un 84.6%, muy bien seleccionadas en más del 60%, principalmente subangulares, con asimetría negativa predominante, distribución leptocurtica, y bajo contenido de carbonato de calcio cercano al 10%. Los datos sugieren que los sedimentos son de origen terrígeno y escasa distancia de transporte hasta el lugar de acumulación. Los vientos predominantes actuales son del noreste, con componentes direccionales secundarios que retrabajan los sedimentos generando dunas transversales, barcanas y longitudinales; las dunas longitudinales son paralelas a la dirección del viento y se presentan colonizadas por vegetación xerofítica favorecida por la inactividad de las mismas. Estas dunas se originaron probablemente por una conjunción de factores como: disponibilidad de sedimentos en una amplia llanura costera relacionada con un nivel marino regresivo, vientos fuertes y persistentes, orientación oblicua de la costa respecto a la dirección del viento, una topografía continental favorable adyacente a la playa, bajo condiciones climáticas distintas a las actuales.

    Damages caused by Gryllus sp. in young seedlings of Eucalyptus grandis were analysed. Three
    experimental groups were tested: Group 1 with 7 days-old and stem diameter of 2.5 mm seedlings; Group 2
    with 49 days-old and 3.33 mm diameter seedlings; and Group 3 with 80 day-old and diameter of 5.75 mm. Each
    group consisted of 12 plants isolated in a cage with a couple of crickets for 15 days. The following daily evaluations
    were made: absence of damage; superficial signs of chewing; deep signs of chewing and stem cuts. Diameter and
    age influenced the occurrence and intensity of damage.

    Full Text Available The present work begins with a brief history of the institute of compensation for damage until the birth of Victimology, moment when the victim came to occupy the center of scientific attention. Due to the evolving of the conceptions of Victimology, the compensation for the damage exerted a strong influence on many aspects of the criminal fact´s analysis. Thus, the study will examine the compensation in an overview of restorative justice, with special attention to the models of mediation and conciliation in order to repair the damage. Then the reparative model will be observed based on the State funds to repair the harm, moment when special attention will be given to Bill of Law of the Senate No. 269 of 2003, which aims to introduce the National Fund for Assistance to Victims of Violent Crimes (FUNAV. After this general analysis, it examines the model of repairing of damage adopted in Brazil, with particular emphasis on the civil action ex delicto, in the mold of Criminal Procedure Code.

    Full Text Available The avocado fruit borer, Stenoma catenifer (Wals. has been a limiting factor in growing avocados over the last years in many Brazilian states. This is a result of the lack of safe and feasible management practices to minimize the fruit borer damage. The aim of this study was to obtain information on the pest biology and ecology as well as on the role of natural enemies to define strategies to control the pest. Samples were taken biweekly and consisted of 20 fruits collected randomly (10 from the upper half and 10 from the lower half of the plant in ten plants, cv. Margarida, in a commercial avocado grove in Arapongas and Cambé regions, PR, from October/2001 to September/2002. Laboratory determinations of the percentage of damaged fruit per plant region, location and number of bored fruit sites, and the number and location of the fruit borer eggs, including parasitized ones, were performed. The results showed that S. catenifer preferred to oviposit and attack fruits located on the upper half of the trees. The majority of the eggs were laid on the fruit pedicel whereas the damage was mainly located on the lower half of the fruits. Trichogrammatids were the most constant and abundant parasitoids found in both localities throughout the study period.A broca-do-abacate, Stenoma catenifer (Lepidoptera: Elachistidae, continua sendo fator limitante para o cultivo do abacate em vários estados do Brasil, nos últimos anos.

    The 2010-2011 exogenous emplacement of a lava lobe during the 2007-2011 lava dome growth at andesitic Volcán de Colima, México, interrupted the previous endogenous regime and allowed us to obtain seismic signals associated with rockfalls triggered by both exogenous and endogenous growth. We analyzed a total of 410 seismic signals of rockfalls with durations from 50 to 150 s recorded during January-April 2010. Two characteristic populations of seismic signal peak frequencies were identified: a low frequency (LF) group (mean = 1.76 ± 0.44 Hz) and a high frequency (HF) group (mean = 3.13 ± 0.63 Hz), associated respectively with rockfalls caused by endogenous and exogenous growth in the crater. Application of the Kolmogorov-Smirnov test showed at the 0.01 significance level that the databases of LF and HF seismic signals of rockfalls belong to different groups of signals and may be considered as having different origins. The results show that the spectral properties of the seismic signals produced by rockfalls may serve as indicators of the origin of falling lava fragments and thus can be used to monitor effusive volcanic activity.

Os tratamentos avaliados foram T1: controle; T2: dano mecânico; T3: 1-metilciclopropeno; T4: dano mecânico + 1-metilciclopropeno; e T5: 1-metilciclopropeno + dano mecânico. Após a aplicação dos tratamentos, os frutos foram armazenados sob condição ambiente (20±2°C/65±5% UR. Os frutos submetidos ao dano mecânico e não tratados com 1-metilciclopropeno apresentaram um maior incremento na produção de etileno. O tratamento dano mecânico não aumentou a atividade respiratória e pouco influenciou o amadurecimento dos frutos, comparado ao controle, porém, aumentou a ocorrência de podridões. O 1-metilciclopropeno reduziu o metabolismo e a perda de qualidade dos frutos. Nos frutos submetidos ao dano mecânico, a aplicação de 1-metilciclopropeno reduziu a incidência de podridões.The objective of this research was to evaluate the effect of the impact injury and treatment with 1-methylcyclopropene on respiration and ethylene production rates and on quality of 'Gala' apples after the storage in controlled atmosphere. The treatments evaluated were: T1: control, T2: mechanical injury; T3: 1-methylcyclopropene; T4: mechanical injury + 1-methylcyclopropene; and T5: 1-methylcyclopropene + mechanical injury. Fruits were then left at ambient conditions (20±2°C/65±5% RH. Fruits submitted to mechanical injury, without the treatment with 1-methylcyclopropene, showed the highest increment of ethylene production. The mechanical injury did not increase the respiratory rate and had small effect on fruit ripening, compared to the control treatment, but increased rot incidence. The 1-methylcyclopropene reduced the metabolism and the loss of fruit quality. In fruits

It appears that even with the participation in rural social movements and the struggle for better working conditions, women have greater social vulnerability in rural areas expressed by the inequality of access to state public services, as well as unequal access the labor market and land tenure, which is reflected in inequalities in health. It was observed that women were exposed to different vulnerabilities and to violence resulting in murder and other situations that affect the health and reflect inequalities of gender, race and class. It was evident that much stills needs to be modified so that the hierarchies of gender are reduced in Brazil. In this sense, it appears that both in the state, and in the Academy this is an issue that still needs to be contextualized and developed, aiming at the structuring of public policy.Este é um texto reflexivo que analisa as situações de vulnerabilidade à violência e danos à saúde na perspectiva de mulheres em cenários rurais. Constata-se que mesmo com a participação nos movimentos sociais rurais e na luta por melhores condições de trabalho, as mulheres apresentam maior vulnerabilidade social no meio rural, expressa pela desigualdade de acesso aos serviços estatais públicos, assim como a desigualdade de acesso ao mercado de trabalho e a posse da terra, que se reflete em desigualdades nas condições de saúde. Observou-se que as mulheres estiveram expostas a diferentes vulnerabilidades e à violência, resultando em assassinatos e em outras situações de comprometimento da saúde que refletem as iniqüidades de gênero, raça e classe. Evidenciou-se que muito necessita ser modificado para que as hierarquias de gênero sejam reduzidas no Brasil.

    Full Text Available RACIONAL: O choque hemorrágico persistente cursa com alta mortalidade. Grande importância tem sido dada para o "controle de danos" como opção terapêutica nestes casos. OBJETIVO: Avaliar a definição, indicações, técnicas e resultados do controle de danos no tratamento dos traumatizados com hemorragia grave. MÉTODO: Revisão bibliográfica. RESULTADOS: Como "controle de danos" entende-se a interrupção da operação antes que o choque hemorrágico alcance a sua fase irreversível, mesmo que as lesões encontradas não tenham o tratamento definitivo neste primeiro momento. Esta alternativa envolve três tempos: a operação abreviada, a recuperação na unidade de terapia intensiva e a reoperação programada. Desta forma, frente à acidose metabólica, hipotermia e coagulopatia, a operação é abreviada através do controle temporário da hemorragia e contaminação. São empregadas técnicas como o tamponamento hepático com compressas e ligadura de eventuais cotos intestinais. Na unidade de terapia intensiva são realizados o aquecimento do doente, restauração da volemia e débito cardíaco, e adequada oferta de oxigênio, além da reposição dos fatores de coagulação. Somente após a estabilização, o traumatizado é levado novamente ao centro cirúrgico para o tratamento definitivo das lesões. Trata-se de uma tática com bons resultados, mas que deve ser restrita a centros especializados, com supervisão cirúrgica contínua e recursos disponíveis para o tratamento de doentes graves. CONCLUSÃO: O controle de danos é opção prática nos casos de hemorragia grave, contudo deve ser empregado com julgamento crítico devido a complicações que podem decorrer da sua indicação.BACKGROUND: Despite the advances in the treatment of exanguinating patients, hemorrhage remains as the leading cause of early deaths. A great deal of attention has been given to "damage control" as a therapeutic alternative in this scenario. AIM: To

    Full Text Available O nível de dano econômico (NDE consiste na quantidade de plantas daninhas que causa impacto no rendimento de grãos da cultura que justifique o custo de seu controle. Os objetivos deste trabalho foram avaliar a possibilidade de utilizar experimentos de eficácia de herbicidas residuais para determinar o NDE, a partir do rendimento de grãos em relação à densidade de plantas de Brachiaria plantaginea (BRAPL que emergem após o tratamento, e avaliar o impacto do preço da cultura e do custo do controle no NDE. A densidade de BRAPL foi determinada em um experimento no qual se realizaram tratamentos químicos que possibilitaram a emergência de diferentes quantidades de plantas e, em conseqüência, vários níveis de interferência sobre a cultura do milho. A avaliação da densidade foi feita aos 10, 20, 30, 40 e 50 dias após a emergência (DAE, de forma a abranger o período crítico de prevenção da interferência. Ao final do experimento foi avaliado o rendimento de grãos da cultura do milho. A resposta da regressão entre densidade de BRAPL e rendimento de grãos de milho ajustou curvas do tipo exponencial decrescente nas avaliações realizadas aos 10 e 20 DAE e curvas do tipo logístico (sigmoidal aos 30, 40 e 50 DAE. O NDE de BRAPL em milho, com base na densidade determinada no início do período crítico de prevenção da interferência (20 DAE, considerando nível de produtividade de 10 t ha-1, variou entre 0,2 e 2,0 plantas m-2, dependendo do preço do milho e do custo do controle. O NDE determinado ao término do período crítico de interferência (50 DAE correspondeu às densidades de BRAPL de 1,5 a 13 plantas m-2. Conclui-se que o NDE de BRAPL na cultura de milho pode ser estabelecido com dados de densidade desta espécie, determinados em experimentos para testes de herbicidas residuais. Assim, o NDE previsto será adequado para situações em que se deseja decidir por aplicações de herbicidas em pós-emergência em

    Full Text Available O objetivo deste trabalho foi avaliar o impacto da redução do inóculo no controle da podridão-'olho-de-boi' (POB causada por Cryptosporiopsis sp. em maçãs e minimização de perdas. Os experimentos foram realizados em Vacaria-RS, nos ciclos 2006/07 e 2007/08. Na fase de dormência de macieiras Pink Lady®, foram aplicados os seguintes tratamentos erradicantes (dose p.i.: calda sulfocálcica (3,0%; oxicloreto de cobre (0,5%; hidróxido de cobre (0,3%; óxido cuproso (0,3% e testemunha sem pulverização. A redução do inóculo foi avaliada em solução oriunda da lavagem de ramos, gemas floríferas e frutos, semeados em meio semisseletivo. Na colheita, a incidência da POB foi avaliada em quatro categorias de frutos: caídos sob a área de projeção da copa; nas plantas; infecções latentes, e após três meses de armazenamento em câmara frigorífica. Houve relação linear positiva entre os níveis de inóculo de Cryptosporiopsis sp. em gemas e os danos por POB (R² = 0,948; P = 0,001. O uso da calda sulfocálcica possibilitou a maior redução de inóculo nas gemas, com redução em 50% dos danos totais ocasionados por POB na safra de 2006/07. Nos frutos, o inóculo apresentou um incremento linear ao longo do ciclo, sendo relativamente maior em 2007/08, onde os tratamentos erradicantes possibilitaram controle superior a 40% nos danos com benefício econômico pela redução do inóculo.Aiming to evaluate strategies for the control of bull's eye rot (BER based on the reduction of initial inoculum the following fungicide treatments were applied in experimental plots established in both 2006/07 and 2007/07 seasons in Vacaria location, southern Brazil, during the plant dormancy period: lime sulfur (3,0%; b copper oxychloride (0,5%; c copper hydroxide (0,3%; and cuprous oxide (0,3%.

    Full Text Available The augmented reality (AR technology has applications in many fields as diverse as aeronautics, tourism, medicine, and education. In this review are summarized the current status of AR and it is proposed a new application of it in weed science. The basic algorithmic elements for AR implementation are already available to develop applications in the area of weed economic thresholds. These include algorithms for image recognition to identify and quantify weeds by species and software for herbicide selection based on weed density. Likewise, all hardware necessary for AR implementation in weed science are available at an affordable price for the user. Thus, the authors propose weed science can take a leading role integrating AR systems into weed economic thresholds software, thus, providing better opportunities for science and computer-based weed control decisions.A tecnologia de realidade aumentada (AR tem aplicações em vários e diversos campos, como aeronáutica, turismo, medicina e educação. Nesta revisão, é resumido o estado atual da AR e propõe-se uma nova aplicação dela na ciência das plantas daninhas. Os elementos básicos para a implementação de algoritmos de AR já estão disponíveis para desenvolvimento de aplicações na área de níveis de dano econômico de plantas daninhas. Estes incluem algoritmos de reconhecimento de imagem, para identificar e quantificar as infestantes por espécie; e software, para a seleção de herbicidas com base na densidade de plantas daninhas. Da mesma forma, todo o hardware necessário para aplicação da AR nessa área da ciência das plantas daninhas está disponível a um preço acessível ao usuário. Assim, sugere-se que a ciência das plantas daninhas possa assumir um papel preponderante na integração dos sistemas de AR aos softwares de níveis de dano econômico de plantas daninhas nas culturas. Com isso, seria possível proporcionar melhor utilização da informática para apoio nas

  17. Vibração: fonte de incômodo à populaçao e de danos às edificações no meio urbano

    Luiz Antonio Brito

    Full Text Available A energia vibratória gerada pelo tráfego de veículos leves e pesados e pelas composições ferroviárias são uma fonte de poluição ambiental pouco estudada no Brasil. A forma mais eficaz de atenuação da energia vibratória é o aumento da distância entre o receptor e a fonte, o que normalmente é obtido com os recuos definidos pelas leis de zoneamento urbano e pela faixa de domínio, tanto de ferrovias como de rodovias. O adensamento das áreas urbanas, já perceptível nas cidades de médio porte, gerado principalmente pela especulação imobiliária, vem aproximando as edificações das principais fontes de vibração no meio urbano. O efeito da energia vibratória nas edificações varia de acordo com o tipo de estrutura e fundação, sua altura e o tipo de solo. As construções que possuem estrutura em aço ou concreto armado tendem a receber melhor os efeitos da vibração (DIN 4150-3,1999. Em contrapartida, as construções antigas e patrimônios históricos, edificados com materiais menos resistentes, em algumas situações mal conservadas, podem sofrer desde trincas estéticas até danos estruturais irreversíveis quando expostas a elevados níveis de vibração. O objetivo deste trabalho é avaliar a incomodidade e os danos estruturais gerados pela energia vibratória induzida pelo tráfego rodoviário e ferroviário em edificações. Os resultados obtidos indicam que os limites de integridade estrutural são atendidos, mas não os de incomodidade.

    Full Text Available The objective of this work was to evaluate the visual and chemical quality of tangerines after mechanical damage by impacts. The tangerine cultivars Montenegrina and Rainha were submitted to different degrees of impact and evaluated for decay and oleocellosis, loss of fresh weight, total soluble solids, total titratable acidity and ascorbic acid degradation, as well as for epicarp color changes. Experiments with three replicates and experimental units of six fruit for each cultivar were done in a completely randomized design. Impact produced qualitative internal and minor external changes on tangerines. The main modifications produced by impact on the fruit were losses of citric acid and soluble solids, which increased the solid:acid ratio, and losses of ascorbic acid. 'Montenegrina' tangerines are more susceptible to internal quality damage than 'Rainha'.O objetivo deste trabalho foi avaliar a qualidade visual e química de tangerinas, após danos mecânicos por impacto. As cultivares de tangerina 'Montenegrina' e 'Rainha' foram submetidas a diferentes graus de impacto e avaliadas quanto à oleocelose e podridão, perda de massa de matéria fresca, sólidos solúveis totais, acidez total titulável e degradação do ácido ascórbico, bem como mudanças na cor do epicarpo. Os experimentos consistiram de três repetições de seis frutos, para cada cultivar, e o delineamento foi inteiramente casualizado. Os impactos produziram mudanças qualitativas internas nas tangerinas, mas as mudanças externas foram mínimas. As modificações mais importantes, produzidas por impacto nas frutas, foram as perdas de ácido cítrico e sólidos solúveis, o que aumentou a relação sólidos:acidez, e as perdas de ácido ascórbico. A tangerina da cultivar Montenegrina é mais susceptível a danos qualitativos internos do que a 'Rainha'.

    Full Text Available A Mata Atlântica vem sendo alvo de biopirataria e coleta predatória de plantas ornamentais como orquídeas que alcançam um alto valor de mercado em função das características estéticas e beleza cênica. O Parque Natural Dom Nivaldo Monte é um fragmento de Mata Atlântica de 64 ha, inserido na Zona de Proteção Ambiental-1 (ZPA-1 do município de Natal, que vem sendo alvo deste mercado ilegal devido à extração vegetal da Cattleya granulosa, uma orquídea endêmica ameaçada de extinção. O objetivo geral deste trabalho é valorar economicamente o dano ambiental ocasionado pela extração ilegal da orquídea C. granulosa. A metodologia utilizada na pesquisa contemplou as seguintes etapas: levantamento amostral da orquídea na área em estudo; cálculo de densidade e freqüência absolutas; valoração econômica do dano ambiental associado à extração indevida; proposição de políticas públicas. Como resultado, foi observada uma densidade de 1,17 indivíduos/parcela e freqüência absoluta de 8,33%, sendo estimando 1493 indivíduos no Parque, durante o período analisado. Os serviços ambientais oferecidos por todos os indivíduos de C. granulosa a sociedade, na área estudada, representa monetariamente um valor de R$ 9.555.200,00. Assim, para manutenção destes serviços propõem-se como políticas públicas municipais para preservação da espécie: aumento da fiscalização na área, educação ambiental com a comunidade circunvizinha, cobrança de indenização ao infrator, investir na interligação da ZPA-1 com a ZPA -3 a fim de propiciar fluxo gênico entre estes fragmentos, assim como incentivar a utilização técnicas de biotecnologia vegetal como a micropropagação de clones e semeadura in vitro para reintrodução na natureza.

    Full Text Available O tabagismo é um grave problema de saúde pública no Brasil. O presente trabalho investigou o uso dos cigarros eletrônicos como possibilidade para reduzir os danos do consumo de tabaco. Realizou-se uma revisão narrativa de literatura, privilegiando artigos em revistas científicas, livros e outras fontes relevantes. Os resultados indicam que dispositivos eletrônicos para fumar podem ser menos prejudiciais à saúde se comparados a cigarros combustíveis e, portanto, têm potencial de serem utilizados para reduzir os danos do consumo de tabaco. Por outro lado, podem levar populações mais vulneráveis à iniciação ao tabagismo e ainda requerem estudos a fim de avaliar os efeitos na saúde a longo prazo. Da mesma forma que os cigarros combustíveis, conclui-se que cigarros eletrônicos, se regulamentados, devem ser submetidos a programas de controles austeros, incluindo, por exemplo, políticas tributárias, de proteção a não fumantes e restrição de publicidade. Smoking is a serious Brazilian public health problem. This work investigated the electronic cigarettes as a possibility to reduce damages of tobacco consumption. The used methodology was the narrative review of the literature, privileging articles in scientific journals, books, and other relevant sources. The results indicate that electronic smoking devices may be less harmful to health if compared to combustible cigarettes and have potential to reduce the harm of tobacco use. On the other hand, such devices may lead vulnerable populations to smoking initiation and still require studies to access their effects on human health in the long term. In the same way as combustible cigarettes, it is concluded that electronic cigarettes, if regulated, should be subjected to austere control programs, including, for example, tax policies, non-smoking protection, and advertising restriction.

    Full Text Available Um dos grandes defeitos ocorrentes no pavimento, ao longo de sua vida útil, é o trincamento por fadiga. Este problema, em geral, se inicia na base do revestimento asfáltico e se propaga para a sua superfície. A caracterização das misturas asfálticas, realizada comumente no Brasil, é baseada no número de ciclos que causam a ruptura no ensaio de fadiga. No entanto, tal número não é um parâmetro mecânico, podendo variar para diferentes condições de contorno. O objetivo do presente artigo é identificar parâmetros mecânicos, referentes ao trincamento por fadiga, do compósito asfáltico com agregado sintético de argila calcinada (ASAC. Para tanto, foi utilizado um modelo viscoelástico de dano contínuo, fundamentado em trabalhos de Shapery, Kim e Lee. Os resultados com o compósito estudado (ASAC mostraram que a perda de rigidez, baseada em uma variável interna de estado, pode ser um critério de fadiga; que o ensaio pode ser realizado para um nível de tensão; a cura de microtrincas durante os períodos de não solicitação da estrutura.One of the major distresses in flexible pavings, throughout its useful life, is the fatigue cracking. This problem, in general, initiates in the base of the asphalt layer and propagates for its surface. The characterization of the asphalt mixtures, carried out in Brazil, is based on the number of cycles that cause the rupture in the fatigue test. However, such number is not a mechanical parameter, varying for different boundary conditions. The objective of the present article is to identify mechanical parameters, referring fatigue cracking, of the asphalt composite with synthetic calcinated clay aggregates (SCCA. To this end, a continuum damage viscoelastic model was used based works from Shapery, Kim and Lee. The results with the composite studied (SCCA had shown: that the loss of rigidity, based on an internal state variable, can be a fatigue criterion; that the test can be carried through

    Full Text Available A abelha-irapuá, Trigona spinipes, é considerada um inseto-praga de várias culturas, por se alimentar de folhas e principalmente de flores e frutos. Os objetivos deste trabalho foram caracterizar o dano provocado pela irapuá em flores de mirtileiro (Vaccinium ashei Read. e avaliar a frutificação efetiva e a qualidade da fruta produzida. O experimento foi conduzido no pomar experimental de mirtileiro, da Embrapa Clima Temperado em Pelotas, RS. Foram marcadas 200 flores de mirtileiro, seleção 103, sendo 100 destas com dano feito pela irapuá e 100 sem o dano. Após a floração, foi observada a frutificação efetiva, e por ocasião da colheita, foram determinados o teor de sólidos solúveis totais (SST, o diâmetro dos frutos e o número de sementes por fruto. O delineamento experimental foi o inteiramente casualizado. Nas flores sem danos da irapuá, houve maior percentagem de frutificação efetiva, e as frutas oriundas das mesmas apresentaram maior diâmetro e maior quantidade de sementes. O teor de SST nas frutas de mirtilo, oriundas tanto das flores com dano como daquelas sem dano, foi semelhante. Esses resultados sugerem que a T. spinipes é prejudicial à cultura do mirtilo, principalmente na época de floração, pois os danos causados pelo inseto provocaram baixa frutificação, frutas de tamanho reduzido e com menor quantidade de sementes.The irapuá Trigona spinipes is considered a pest insect of several crops because it feeds on their leaves, flowers and fruits. The aim of this study was to characterize the damage caused by irapuá on blueberry flowers (Vaccinium ashei over the fruit set and fruit quality.

    É sabido que as condições das rodovias brasileiras têm grande impacto sobre a economia nacional. Diante disso, nasce a necessidade de uma busca por métodos de análise de pavimentos que possam prever com maior precisão as falhas as quais o pavimento está submetido. Dentre os principais métodos utilizados atualmente, pode-se citar os métodos puramente empíricos e aqueles mecanístico-empíricos que fazem uso da resposta estrutural do pavimento. A aprimoração de técnicas numéricas como o Método dos Elementos Finitos (MEF ou o Método dos Elementos de Contorno (MEC tem feito com que os métodos mecanístico-empíricos ganhem cada vez mais espaço e sejam mais usados no dimensionamento de pavimentos. O presente trabalho apresenta um modelo mecanístico que considera a evolução do dano causado pelos carregamentos e, conseqüentemente, possibilita uma melhor simulação da vida de fadiga da camada asfáltica. O modelo também possibilita uma melhor modelagem do acúmulo de deformação permanente nos pavimentos através do uso da Teoria da Viscoelasticidade, permitindo assim avaliar as duas principais falhas dos pavimentos flexíveis.

    Full Text Available Laminados compósitos com matrizes poliméricas, respectivamente termorrígida e termoplástica, fortalecidas com fibras contínuas de carbono foram submetidos a impacto único transversal com diferentes níveis de energia. Os danos impingidos aos materiais estruturais foram avaliados por termografia ativa infravermelha na modalidade transmissão. Em geral, os termogramas do laminado termoplástico apresentaram indicações mais claras e bem definidas dos danos causados por impacto, se comparados aos do compósito termorrígido. O aquecimento convectivo das amostras por fluxo controlado de ar quente se mostrou mais eficaz que o realizado por irradiação, empregando-se lâmpada de filamento. Observou-se também que tempos mais longos de aquecimento favoreceram a visualização dos danos. O posicionamento da face impactada do espécime, relativamente à câmera infravermelha e à fonte de calor, não afetou a qualidade dos termogramas no caso do laminado termorrígido, enquanto que influenciou significativamente os termogramas do compósito termoplástico. Os resultados permitiram concluir que a termografia infravermelha é um método de ensaio não-destrutivo simples, robusto e confiável para a detecção de danos por impacto tão leve quanto 5 J em laminados compósitos poliméricos reforçados com fibras de carbono.Continuous carbon fiber reinforced thermoset and thermoplastic composite laminates were exposed to single transversal impact with different energy levels. The damages impinged to the structural materials were evaluated by active infrared thermography in the transmission mode. In general, the thermoplastic laminate thermograms showed clearer damage indications than those from the thermosetting composite. The convective heating of the samples by controlled hot air flow was more efficient than via irradiation using a filament lamp. It was also observed that longer heating times improved the damage visualization. The positioning of the

    Com a finalidade de avaliar os danos causados por Spodoptera frugiperda (J. E. Smith, 1797 na produção do algodoeiro, foi conduzido o presente trabalho. Foram utilizados quatro níveis de infestação artificial aos 75 e 95 dias da germinação das plantas. As avaliações foram feitas através da produção de algodão em caroço, por parcela. As diferenças na produção em plantas infestadas aos 75 e 95 dias da germinação, comparadas com a testemunha, foram estatisticamente significativas para as infestações com 1, 2 e 4 lagartas por planta. Aos 75 dias, devido ao fato de existirem poucos órgãos frutíferos, a redução na produção deu-se devido ao ataque das lagartas aos ponteiros e aos caules, com corte parcial ou total. Na infestação aos 95 dias a produção diminuiu linearmente em relação aos diferentes níveis de infestação; nesta época as lagartas mostraram preferência pelas estruturas frutíferas do algodoeiro.

    This work was conducted with the purpose of evaluate the damages provoked by Spodoptera frugiperda (J. E. Smith, 1797 in cotton-plant yield. To evaluate the decrease in the cotton yield four levels of artificial infestation were used at 75 and 95 days from plant germination. The damage was evaluated on cotton seeds per plot. The differences in the yield of infested plants at 75 and 95 days from germination, when compared to the check, were statistically significant for the infestations of 1, 2 and 4 larvae per plant. At 75 days when the plants presented a low number of fruit organs, the yield decrease was due to the attack of larvae cutting partially or totally the shoots and stems. As to the infestation at 95 days the yield decreased linearly in relation to the different levels of infestation; at this time the larvae showed a preference for the fruit

    Full Text Available Bananas respond at the physical and physiological level to mechanical damage. Mechanical injuries cause alterations in color and flavor, tissue softening, faster ripening, increased weight loss, increased invasion of microorganisms, and higher enzyme activity in the affected area. The purpose of this study was to verify the physical and metabolic alterations in 'Prata Anã' bananas induced by mechanical stress at room temperature. The experiment was conducted in a completely randomized, split-plot in time design, consisting of one control and four mechanical injury types: cutting, abrasion, impact and compression, sampled over time. The percentage of accumulated and daily fresh weight loss, electrolyte leakage from the injured peel region, total soluble sugar and starch contents and enzyme activity of polyphenoloxidase and peroxidase were measured. The damage caused by cutting and abrasion resulted in the highest percentage of fresh weight loss. All types of mechanical damage increased electrolyte leakage during the evaluation period, in comparison with the control. The impact damage anticipated the ripening, besides affecting the conversion of starch into total soluble sugars in the pulp. By impact and abrasion injuries, the polyphenoloxidase and peroxidase activity in the peel was increased by up to 231% and 90%, and 618% and 956%, respectively, compared to the control.Bananas apresentam respostas físicas e fisiológicas ao dano mecânico.

    Full Text Available A adoção do conceito de nível de dano econômico (NDE no manejo de plantas daninhas avalia suas populações de modo que medidas de controle sejam implementadas somente quando as infestações superarem os NDEs. O objetivo deste trabalho foi definir o NDE para infestações mistas das espécies Bidens pilosa e Bidens subalternans na cultura da soja. Foram conduzidos experimentos em campo em dois locais: Passo Fundo e Eldorado do Sul, RS. Os tratamentos constaram de densidades mistas das espécies de picão-preto e semeadura da soja aos 3, 7 e 11 dias após dessecação da cobertura vegetal. Obtiveram-se valores para NDE variáveis de 0,4 a 33 plantas m-2. Foram verificadas respostas diferentes nas relações de interferência cultura-plantas daninhas entre os locais estudados. O atraso na semeadura da soja em relação à dessecação da cobertura vegetal incrementa o grau de interferência de picão-preto na cultura. Detectou-se que aumentos na perda de rendimento por unidade de planta daninha, no potencial de rendimento da cultura, no valor do produto colhido e na eficiência do herbicida diminuem os valores de NDE, tornando potencialmente mais econômico o controle; já aumento no custo do controle das plantas daninhas faz elevar os NDEs. Constatou-se que as sementes produzidas por plantas não-controladas, ocorrendo em densidades abaixo do NDE, comprometem a adoção da tomada de decisão de controle com base neste critério.Adoption of the threshold level (TL concept for weed management evaluates weed populations to implement control measures only when infestations overcome the TL.

    Full Text Available Resistance to thermal shock damage is an important characteristic in refractory materials, since it determines their performance and service life in many applications. Therefore, the use of more sensitive techniques is desirable to improve the evaluation of thermal shock damage and monitoring of nucleation and propagation cracks and microcracks.The aim of this work was to evaluate the potential of damping change characterization to quantify thermal shock damage and to estimate the retained mechanical strength in complement to the dynamic Young's modulus test. Variations in damping and retained Young's modulus and their correlation with the mechanical strength of a high alumina refractory castable were evaluated at different thermal shock temperatures and number of cycles. The changes in damping were proportional to the retained mechanical strength, similarly to the retained Young's modulus. Changes in damping were also detected which were not indicated by the Young's modulus measurements.A resistência ao dano por choque térmico é uma característica importante dos materiais refratários visto que determina o desempenho e vida útil destes materiais em várias aplicações. Portanto é desejável a aplicação de técnicas mais sensíveis para avaliação do dano por choque térmico e monitoração da nucleação e expansão de trincas e microtrincas. O objetivo deste trabalho foi avaliar o potencial da caracterização da variação do amortecimento para quantificar o dano por choque térmico e para estimar o módulo de ruptura retido, complementarmente à caracterização do módulo de Young dinâmico. Foram estudadas as variações do amortecimento, do módulo de Young retido e a correlação destas variações com a resistência mecânica de um concreto refratário de alta alumina para distintas variações de temperatura e número de ciclos. As alterações encontradas no amortecimento foram proporcionais à resistência mecânica retida

Para a avaliação dos pontos críticos e registro da magnitude dos impactos, foi usada uma esfera instrumentada. Os pontos críticos de transferência demonstraram valores de aceleração entre 30 e 129 G (m s-2. Os testes laboratoriais evidenciaram que superfícies acolchoadas reduziram em até 31% a magnitude de impacto. A incidência de danos físicos internos foi crescente e atingiu 79% em superfícies rígidas para a maior altura de queda livre. Por outro lado, observou-se redução na incidência de danos físicos nos frutos quando superfícies protetoras foram utilizadas, verificando-se na altura de 10 cm um limite mínimo de 5% de danos severos, enquanto para superfície rígida o mínimo correspondeu a 10%. As variáveis de qualidade foram alteradas, verificando-se maior perda de massa, maiores valores de acidez total, menores valores de ácido ascórbico e sólidos solúveis para maiores alturas de queda livre sobre superfícies rígidas.Tomatoes are one of the most important vegetable crops grown in Brazil and are among the crops that have one of the highest post-harvest losses indexes in the country.

Sob essas condições, o estresse salino causou redução nos parâmetros de trocas gasosas, como fixação de CO2, condutância estomática e transpiração, mas ao contrário, não alterou a eficiência fotoquímica do fotossistema II. Após 14 dias de tratamento, os íons salinos atingiram concentrações muito elevadas nas folhas, provavelmente atingindo níveis tóxicos. Em tais condições, as trocas gasosas e a atividade fotoquímica sofreram forte redução causada pelo estresse iônico. O tratamento de recuperação não induziu queda intensa nas concentrações dos íons salinos nas folhas e nenhuma melhoria foi observada no desempenho fotossintético. Plantas jovens de pinhão manso são sensíveis a condições de salinidade elevada por NaCl, mostrando altas concentrações de Na+ e Cl-, baixa razão K+/Na+ e danos fotossintéticos intensos causados tanto por limitações estomáticas como por limitações bioquímicas.

    Full Text Available Na cultura do arroz irrigado ocorrem elevadas perdas de produtividade de grãos devido à interferência de plantas daninhas, pois estas também estão adaptadas ao ambiente inundado de cultivo do cereal. Objetivou-se avaliar a interferência e determinar o nível de dano econômico de populações de capim-arroz em arroz irrigado em função do arranjo de plantas da cultura. Foi realizado um experimento em campo, com cultivo de arroz em sistema convencional. Os tratamentos foram constituídos por três arranjos de plantas de arroz, cultivar BRS Pelota (17 e 32 cm e semeadura a lanço, e nove populações de capim-arroz em cada método de semeadura. O modelo de regressão não linear da hipérbole retangular estima adequadamente as perdas de produtividade do arroz irrigado na presença de plantas de capim-arroz. A cultura do arroz semeada a lanço apresenta maior habilidade competitiva com o capim-arroz em relação à semeadura em linha nos espaçamentos de 17 e 32 cm. A variável área foliar apresenta melhor ajuste ao modelo da hipérbole retangular, comparativamente às variáveis população de plantas, massa seca da parte aérea e cobertura do solo. A utilização de semeadura a lanço aumenta o nível de dano econômico, justificando a adoção de medidas de controle do capim-arroz em níveis mais elevados de população. Acréscimo na produtividade de grãos, no preço do arroz e na eficiência do herbicida e redução no custo de controle diminuem os valores do nível de dano econômico, justificando a adoção de medidas de controle em baixas populações de capim-arroz.High yield losses in irrigated rice occur due to weed interference, as weeds are also adapted to the flooded environment where the crop is cultivated. The objective of this study was to evaluate the degree of interference and determine the economic weed threshold of populations of barnyardgrass in irrigated rice, according to crop arrangement.

    Full Text Available Fluoride has been widely used in dentistry because it is a specific and effective caries prophylactic agent. However, excess fluoride may represent a hazard to human health, especially by causing injury to genetic material. Genotoxicity tests represent an important part of cancer research to assess the risk of potential carcinogens. In the current study, the potential DNA damage associated with exposure to fluoride was assessed by the single cell gel (comet assay in vitro. Chinese hamster ovary cells were exposed to sodium fluoride (NaF at final concentration ranging from 7 to 100 µg/ml for 3 h, at 37°C. The results pointed out that NaF in all concentrations tested did not contribute to DNA damage as depicted by the mean tail moment and tail intensity. These findings are clinically important since they represent an important contribution to a correct evaluation of the potential health risk associated with the exposure to dental agents.O flúor tem sido amplamente usado na Odontologia, pois é um agente profilático efetivo e específico contra a cárie dentária. Entretanto, o flúor em excesso pode representar perigos à saúde humana, especialmente por causar agressão ao material genético.

The characteristics skin color, firmness, titratable acidity and soluble solids content and the incidence of the postharvest damages were evaluated periodically in avocados sampled in three different stages in a packinghouse (arrival, pallet and processed fruits after storage for 30 days at 5ºC. For diseases control, ‘Hass’ avocado were treated by immersion with the following products: azoxystrobin, benzalkonium chloride, chlorine dioxide, Ecolife®, sodium hypochlorite, imazalil, prochloraz and thiabendazole. In general, the highest physical chemical changes were observed in fruits collected at their arrival to the packinghouse and in processed fruits after stored for 30 days at 15 days of storage at 25°C. The rots incidence was 56,7% in ‘Fuerte’ and 75,7% in ‘Hass’. Lower incidence of rots was observed in fruits sampled at the pallet and a higher incidence in the processed fruits, after refrigerated storage. Anthracnose was the most important disease in both cultivars. The mechanical injuries increased with the processing stages; however, they did not influence the incidence of the rots. Procloraz and imazalil were the most efficient fungicides in reducing the incidence of rots.

After the treatments all groups were observed for 24 h. Pilocarpine group presented seizures which progressed to status epilepticus in 75% of the animals. Pretreatment with AA led to a reduction of 50% of this rate. Results showed that pretreatment with AA did not alter reference memory when compared to a control group. In the working memory task, we observed a significant day's effect with important differences between control, pilocarpine and AA plus pilocarpine groups. Pilocarpine and AA plus pilocarpine groups had 81 and 16% of animals with brain injury, respectively. In the hippocampus of pilocarpine animals, it was detected an injury of 60%. As for the animals tested with AA plus pilocarpine, the hippocampal region of the group had a reduction of 43% in hippocampal lesion. Our findings suggest that seizures caused cognitive dysfunction and neuronal damage that might be related, at least in part, to the neurological problems presented by epileptic patients.

    The proliferative activity of CFU-S, low in normal steady state, increases after treatment with different aggressors, i.e., radiation. This stimulation has been attributed in part to a local regulation system of stem cell proliferation, and at least in part to a humoral regulatory system. In the present work it has been investigated the role that circulating activities have in the CFU-S stimulation, by means of in vitro and in vivo incubation assays with diffusion chambers. The results show that bone marrow of mice irradiated with 5 Gy produces in vitro diffusible activities capable of stimulating the CFU-S proliferation. As well with this same dose circulating activities are also produced in vivo. In addition we have observed that these activities are only released during the periods of active hematopoietic regeneration that follow irradiation with moderate doses (1.5 and 5 Gy). In another set of experiments we saw that the stimulating activities are also detected in serum of mice irradiated with 5 Gy. These serum activities modify the proliferative state of very primitive precursors (12 d CFU-S). When the serum activities are added to long term bone marrow cultures the CFU-S are also stimulated to proliferate. Finally, we observed that the radiation-induced serum activities stimulate the proliferation of bone marrow CFU-S when injected into normal mice, suggesting that such activities are involved in the regulation of CFU-S proliferation.

For it it was elaborated a methodology and procedure for test tubes type Charpy according to the standard before mentioned. Due to the ferritic steels are used mainly in pressure vessels to the reactor (RPV) of nuclear power plants; in the samples it was simulated the effect of the damage for irradiation through a thermal treatment that induced the precipitation of the carbides and sulfurs in the limits of grain (one of the modifications suffered in the irradiated materials); it was made a comparison later with material samples in initial state (without thermal treatment), used as witness sample, by means of assays of fracture mechanics, specifically flexion in three points; this way with it to observe the effect of the damage for irradiation in the reference temperature (T{sub 0}). This temperature (T{sub 0}) it is a very important parameter in the mechanical property of the material called fracture tenacity; which at the moment gives the rule for the verification of structural integrity of the RPV. As a result of this it was observed an increase in the reference temperature in the material in fragilezed state with respect to the initial state of 31.75 C.

    The artificial defoliation allows to measure the defoliation intensity caused by insects. The objectives of this work were to evaluate the damages caused by leaf-cutting ants in young plantations of Pinus taeda and Eucalyptus grandis using different levels of artificial defoliation. A classification was established according to defoliation levels that were caused by leaf-cutting ants in P. taeda: level 1: 50%, level 2: 75%, level 3: 100% and level 4: 100%, including the cut of the apical meristem. And in E. grandis: level 1: 50% of defoliation; level 2: 75% and level 3: 100%. After one year, the P. taeda seedlings had losses in diameter and height for defoliation level above 75%. Seedlings severely defoliated (level 4, had losses of 37.0% in height and 45.4% in diameter. The E. grandis seedlings had losses since three months old and the reductions were proportional to the defoliation intensity. After one year, the losses of 13.3% in height and 20% in diameter were verified in plants with 100% of defoliation. P. taeda plants are more damaged by leaf-cutting attack.

    As dificuldades constatadas na colheita mecanizada do feijoeiro ainda constitui em um obstáculo para a expansão da cultura. Diante disto, o CNPAF vem se esforçando para o melhoramento da espécie buscando características adequadas à colheita mecanizada. A cultivar Safira atende a este objetivo. Neste sentido foi realizado um experimento na Fazenda Três Irmãos, no município de Santa Helena de Goiás (GO, onde se compararam três sistemas de colheita, objetivando avaliar perdas de grãos, bem como a qualidade do produto colhido, através da análise de grãos quebrados e impurezas, na cultivar Safira. Os resultados demonstraram que a colheita mecanizada do feijoeiro para a cultivar Safira é viável. A automotriz recolhedora causa menor perda de grãos, mas o dano mecânico é elevado; a recolhedora-trilhadora apresentou perda satisfatória, apesar de exigir manuseio adequado.

    The mechanization of the crop of the bean still constitutes an obstacle for the expansion of the culture. Due to this fact, CNPAF is making an effort to the improvement of the species looking for favorable characteristics to the mechanized crop. The cultivar ‘Safira’ fulfills this aim. In this sense, an experiment was carried out at Fazenda Três Irmãos, in the district of Santa Helena of Goiás (GO. Three crop systems were tested in order to evaluate losses of grains and the quality of the picked product, through analysis of broken grains and sludges. The results demonstrated that the mechanized crop of bean concerning the cultivar ‘Safira’ is viable. The self-driven retirement causes a smaller loss of grains, but the mechanical damage is higher; the retirement-thrashing showed satisfactory loss, despite of requiring

    Full Text Available Este trabalho teve como objetivos avaliar o efeito do ensacamento dos frutos de macieira na incidência de danos causados por insetos-praga, sarna, "russeting" e queimadura pelo sol, além da praticidade dos diferentes tipos de embalagens utilizadas no ensacamento. O estudo foi conduzido no pomar orgânico de macieira da empresa Fischer Fraiburgo Agrícola Ltda, em Fraiburgo-SC, na safra 2004-2005. O delineamento experimental foi o de blocos casualizados. Os tratamentos foram: a frutos não ensacados (testemunha, e b frutos ensacados, seguido de desensacamento aos 15 e 7 dias antes da colheita, e na colheita. Ensacaram-se, por tratamento, 150 frutos da cultivar Royal Gala e 300 frutos da cultivar Suprema, utilizando-se de dois tipos de embalagens: saco de papel-manteiga parafinado branco e de polipropileno microperfurado transparente. Observou-se que o ensacamento reduziu o ataque de pragas em relação aos frutos não ensacados. Porém, a sarna desenvolveu-se, tanto em frutos ensacados, quanto em não ensacados. Em geral, houve menos frutos com "russeting", com a antecipação da retirada dos sacos. A embalagem de polipropileno é mais fácil de ser manuseada, resiste à chuva e ao granizo, e apresentou menor custo que a de papel; entretanto, facilitou a queimadura de frutos pelo sol, principalmente quando se encontra muito aderida à epiderme destes.This study had as objective the evaluation of fruit bagging effect on the damage incidence caused by insect pests, apple scab, russeting and sunburn on apple fruits, and the practicity of different bagging bags used in organic apple orchard. The study was carried out at Fischer Fraiburgo Agrícola Ltda, in Fraiburgo, SC. It was used a completely randomized block design. The treatments were applied as follows: a no bagging fruits (control; b bagging fruits, followed by the unbagging at 15 and 7 days before harvest, and on the harvest day. It was bagged per treatment, 150 'Royal Gala' fruits and 300

    Full Text Available Admite-se a hipótese de que aspectos econômicos como o custo de controle e o valor monetário dos grãos devem ser utilizados como critério para determinar o período aceitável de interferência das plantas daninhas antes de se decidir pelo seu controle. O período inicial assim obtido foi denominado Período Anterior ao Dano no Rendimento Econômico (PADRE. Desenvolveu-se um modelo matemático utilizando-se os aspectos econômicos citados, parametrizou-se o modelo com base em resultados da literatura e foram feitas diversas simulações. Os resultados permitiram confirmar a hipótese de que o custo do controle das plantas daninhas e o preço dos grãos da cultura podem ser utilizados como bons indicadores dos períodos de interferência. O PADRE diminui com o incremento do preço da cultura, ou com a redução do custo de controle, ou com o aumento do potencial produtivo da cultura, indicando que, nessas condições, o controle precoce das plantas daninhas é economicamente justificável. O trabalho aponta algumas limitações encontradas na literatura científica e soluções para se obter o PADRE e os demais períodos de interferência.This work hypothesizes economic aspects, such as weed control cost and grain price, should be used as criteria to determine weed interference periods in the crops to support weed control decisions. The weedy period based on such parameters was termed weedy period prior to economic loss (WEEPPEL. A mathematical model was developed based on the abovementioned economic aspects, model parameters were searched in the literature, and simulations performed. The simulation results allowed confirming the hypothesis that weed control cost and grain price are good criteria to determine weed interference periods. WEEPPEL decreases with increasing crop grain prices, or decreasing weed control costs, or increasing crop potential yield, suggesting that under these conditions very early weed control is economically

    Full Text Available To prevent or mitigate an AIDS epidemic among injecting drug users (IDUs, effective activities need to be implemented on a large enough scale to reach and assist sufficient numbers of drug users and thereby change their risk behaviors related to drug use and sex. Recent work by UNAIDS on "high coverage sites", adopting the above strategies, has shown that one of the key elements in achieving high coverage is ongoing and sophisticated advocacy. High coverage harm reduction sites were studied through literature search and site visits, including key informant interviews, review of service statistics, and data analysis, in order to document the steps that led to scaling up, the way coverage was defined in these sites, and the lessons learned from their efforts. Syringe-exchange programs can achieve high coverage of IDUs. Monitoring to determine regular reach (those who are in regular contact with harm reduction services should be added to uniform data collection carried out by harm reduction programs. Advocacy is crucial to achieving high coverage.Para prevenir ou mitigar uma epidemia de AIDS entre usuários de drogas injetáveis (UDI, atividades eficazes devem ser implementadas numa escala suficiente para atingir e ajudar um número suficiente de usuários e, portanto, modificar seus comportamentos de risco em relação ao uso de drogas e práticas sexuais.

    Full Text Available O fungo Phakopsora pachyrhizi Sydow & Sydow representa grande ameaça à sojicultura nas principais regiões produtoras do mundo, onde significativas perdas foram relatadas. Na quantificação de danos causados, muitas são as variáveis a serem estudadas, como área abaixo da curva de progresso da doença (AACPD, absorção de luz da área foliar sadia (HAA e duração da área foliar sadia (HAD, além das curvas de progresso da doença. Neste trabalho, objetivou-se verificar a influência de diferentes herbicidas e fungicidas no progresso da doença, bem como suas implicações nas variáveis referentes à área foliar sadia e à produtividade da cultura. Os tratamentos testados em duas cultivares ('MG/BR46 Conquista' e 'BRS Valiosa RR' foram: 1. Testemunha; 2. Testemunha com herbicidas; 3. Herbicidas e pyraclostrobin (V4 + pyraclostrobin + epoxiconazole (R2 e R5.1; 4. Herbicidas e pyraclostrobin (V4 + epoxiconazole (R2 e R5.1; e 5. Herbicidas (V4 + pyraclostrobin + epoxiconazole (R2 e R5.1. Os herbicidas utilizados em 'MG/BR-46 Conquista' foram sethoxydim, bentazon e chlorimuron-ethyl, sendo utilizado glyphosate na 'BRS Valiosa RR'. O modelo logístico foi o que melhor se adequou à severidade média das avaliações e à curva de progresso da doença. Para o terço inferior, posição do dossel mais propícia à doença, o modelo logístico com taxa variável foi o que mais se ajustou aos dados. A pulverização de pyraclostrobin + epoxiconazole reduziu a taxa de desenvolvimento de P. pachyrhizi em relação à epoxiconazole. A utilização da mistura influenciou as variáveis AACPD, HAA e HAD, sendo estas consideradas apropriadas para a quantificação dos danos provocados pela ferrugem asiática. Na 'MG/BR-46 Conquista', a ação dos herbicidas afetaram temporariamente a área foliar, atingindo indiretamente as variáveis HAA e HAD.Phakopsora pachyrhizi Sydow & Sydow is the worst threat for soybean crop in the most important growing

  10. Geophysics- and geochemistry-based assessment of the geochemical characteristics and groundwater-flow system of the U.S. part of the Mesilla Basin/Conejos-Médanos aquifer system in Doña Ana County, New Mexico, and El Paso County, Texas, 2010–12

    One of the largest rechargeable groundwater systems by total available volume in the Rio Grande/Río Bravo Basin (hereinafter referred to as the “Rio Grande”) region of the United States and Mexico, the Mesilla Basin/Conejos-Médanos aquifer system, supplies water for irrigation as well as for cities of El Paso, Texas; Las Cruces, New Mexico; and Ciudad Juárez, Chihuahua, Mexico. The U.S. Geological Survey in cooperation with the Bureau of Reclamation assessed the groundwater resources in the Mesilla Basin and surrounding areas in Doña Ana County, N. Mex., and El Paso County, Tex., by using a combination of geophysical and geochemical methods. The study area consists of approximately 1,400 square miles in Doña Ana County, N. Mex., and 100 square miles in El Paso County, Tex. The Mesilla Basin composes most of the study area and can be divided into three parts: the Mesilla Valley, the West Mesa, and the East Bench. The Mesilla Valley is the part of the Mesilla Basin that was incised by the Rio Grande between Selden Canyon to the north and by a narrow valley (about 4 miles wide) to the southeast near El Paso, Tex., named the Paso del Norte, which is sometimes referred to in the literature as the “El Paso Narrows.”Previously published geophysical data for the study area were compiled and these data were augmented by collecting additional geophysical and geochemical data. Geophysical resistivity measurements from previously published helicopter frequency domain electromagnetic data, previously published direct-current resistivity soundings, and newly collected (2012) time-domain electromagnetic soundings were used in the study to detect spatial changes in the electrical properties of the subsurface, which reflect changes that occur within the hydrogeology. The geochemistry of the groundwater system was evaluated by analyzing groundwater samples collected in November 2010 for physicochemical properties, major ions, trace elements, nutrients, pesticides

    This work presents a general perspective on cementing and formation damage. Few relative experiments to the damage to the formation, that they involve the casing activity and cementing, consider all the factors that affect these operations. So that she can analyze the contribution of a primary cementing has in the formation damage , it should be considered, also, the contribution of the drilling fluid and of the operation of the perforation. With base in experimental data of several accomplished studies, it can be concluded that a primary cementing has small, or any, contribution in the decrease of the productivity of an oil well.

    Full Text Available O nível de dano econômico (NDE para monitoramento das infestações de capim-arroz em lavouras de arroz irrigado permite adotar medidas de manejo na cultura e usar herbicidas de maneira racional. Objetivou-se com o trabalho determinar NDE para capim-arroz, presente em lavouras de arroz irrigado, calculado na base de um único ano, em função de populações de capim-arroz, de cultivares de arroz e de épocas de entrada de água na lavoura. Para isso, foram conduzidos dois experimentos em delineamento experimental completamente casualizado, sem repetição. No primeiro experimento, os tratamentos foram constituídos de seis cultivares de arroz: BRS-Atalanta e IRGA 421 (ciclo muito curto, IRGA 416, IRGA 417 e Avaxi (ciclo curto e BRS-Fronteira (ciclo médio; e dez populações de capim-arroz. No segundo experimento usaram-se como tratamentos épocas de início da irrigação: 1, 10 e 20 dias após aplicação dos tratamentos herbicidas (DAT; e populações de capim-arroz. Os NDEs estimados para o capim-arroz variaram em função das práticas de manejo adotadas na cultura do arroz irrigado. Os NDEs estimados para os cultivares de arroz IRGA 416 e 417 foram superiores aos dos demais cultivares quando em competição com capim-arroz. O atraso da entrada de água diminui os NDEs para o cultivar de arroz BRS-Pelota. Aumentos nas perdas de produtividade por unidade de planta daninha, no potencial de produtividade da cultura, no valor do produto colhido e na eficiência do herbicida e diminuição do custo de controle reduziram os NDEs, tornando econômica a adoção de práticas de manejo sob baixas populações de capim-arroz em competição com arroz irrigado.Economic weed threshold (EWT for monitoring barnyardgrass infestation in flooded rice farms allows the adoption of crop management measurements and a rational use of herbicide. The objective of this study was to determine EWT for barnyardgrass based on a single year in function of

    Full Text Available In addition to antioxidative effects, estrogens also exert pro-oxidative actions. The effect of chronic administration of a high dose of estradiol valerate on Morris water maze tasks and brain tissues oxidative damage was investigated. The Sham-Est and OVX-Est groups were treated with estradiol valerate (4 mg/kg for 12 weeks. Escape latency and traveled path in the Sham-Est and OVX-Est groups were significantly higher than in the Sham and OVX groups (p≪0.01 and p≪0.001. In the probe trial, the animals of the Sham-Est and OVX-Est groups spent lower time in Q1 compared to Sham and OVX groups (p≪0.05 and p≪0.001. In Sham-Est and OVX-Est groups, the brain tissue total thiol concentration was significantly lower, and malondialdehyde (MDA concentrations were higher than in the Sham and OVX groups (p≪0.05 and p≪0.001. It is concluded that administration of high exogenous levels of estradiol impairs performance and enhances oxidative stress.Além dos efeitos antioxidantes, os estrógenos também têm ação pró-oxidativa. Foi investigado o efeito da administração crônica de alta dose de valereato de estradiol no desempenho do labirinto aquático de Morris e o dano oxidativo ao tecido cerebral. Os grupos Sham-Est e OVX-Est foram tratados com valereato de estradiol (4 mg/kg por 12 semanas. O tempo de latência para escapada e o caminho percorrido foram significativamente maiores nos grupos Sham-Est e OVX-Est em relação aos grupos Sham e OVX (p≪0,01 e p≪0,001. No estudo probe, os animais dos grupos Sham-Est e OVX-Est levaram menos tempo no Q1 em comparação aos grupos Sham e OVX (p≪0,05 e p≪0,001. Nos grupos Sham-Est e OVX-Est, a concentração total de tiol foi significativamente menor, enquanto a concentração de malondialdehydo (MDA for maior do que aquela dos grupos Sham e OVX (p≪0,05 e p≪0,001. Concluiu-se que a administração de altas doses de estradiol exógeno compromete o desempenho e aumenta o estresse oxidativo

As injeções de ácido ascórbico ou α-tocoferol antes da administração de pilocarpina reduzem o número de animais que convulsionam. Estes achados sugerem que os radicais livres podem induzir o desenvolvimento de lesão cerebral durante as crises epilépticas. No modelo P400, o ácido ascórbico e o α-tocoferol, diminuem significativamente os danos cerebrais. Os compostos antioxidantes podem exercer efeitos neuroprotetores, e esses resultados podem estar associados à inibição da produção de radicais livres. Estes resultados sugerem um promissor potencial terapêutico tanto para o ácido ascórbico quanto para o α-tocoferol no tratamento de doenças neurodegenerativas.

    Full Text Available Barbados cherry is a tropical fruit that when cultivated in subtropical areas is exposed to frosts which cause considerable damages to the leaves and can kill plants. The frosts of July 2000 in Northern Paraná State made possible the evaluation of 19 Barbados cherry genotypes propagated through cuttings. A minimum air temperature of –1,3°C was recorded on 17 July at the meteorological station; the minimum ground temperature was around –5,4°C. All plants were severely injured in 100% of leaves. The evaluation was made the following year to the frost, through sprouts status. It was observed that Barbados cherry genotypes present differences in cold hardiness. Some genotypes were killed and others survived, with good vegetation on the next year. The following genotypes presented the best recovery: ‘Cícero’, ‘Roseli’, ‘Carolina’ and ‘Lígia.’ The findings are discussed in relation to temperature limits reported in the literature.A aceroleira é uma planta de clima tropical que também tem sido cultivada em áreas subtropicais, ficando com isso sujeita à ocorrência de geadas, que causam danos consideráveis à folhagem e podem levar as plantas à morte. As geadas de julho de 2000 no Norte do Paraná possibilitaram a avaliação de 19 genótipos de acerola, propagados vegetativamente. A temperatura mínima foi de –1,3° C no abrigo meteorológico em 17 de julho, que corresponde a – 5,4 °C na relva. Todas as plantas tiveram danos em 100% das folhas. No ano seguinte à geada, avaliou-se a recuperação das plantas com base na brotação apresentada. Com os resultados obtidos, conclui-se que os genótipos de aceroleira apresentam respostas diferentes à geada, sendo que alguns são levados à morte e outros conseguem se recuperar na estação de crescimento seguinte. Os genótipos que apresentaram melhor recuperação foram: ‘Cícero’, ‘Roseli’, ‘Carolina’ e ‘Lígia’. Os resultados são discutidos em rela

    Full Text Available A retinopatia diabética é a principal causa de cegueira legal irreversível em adultos na idade produtiva. Estima-se que o número de pessoas com risco de desenvolver perda de visão decorrente do diabetes dobre nos próximos 30 anos. Alguns estudos sugerem que alterações neurodegenerativas ocorram antes do comprometimento vascular. Essas alterações incluem aumento da apoptose neural, reatividade de células gliais, ativação microglial e metabolismo alterado do glutamato, e podem explicar algumas das deficiências funcionais que ocorrem logo após o início do diabetes, como alterações precoces no eletrorretinograma. O presente artigo de revisão visa apresentar evidências atuais que apontem a neurodegeneração como possível evento inicial da retinopatia diabética.Diabetic retinopathy is the leading cause of irreversible legal blindness in working-age adults. The number of people worldwide at risk of developing vision loss from diabetes is predicted to double over the next 30 years. Some elements suggest that neurodegenerative changes occur beyond vascular damage. These changes include increased apoptosis, glial cell reactivity, microglial activation, and altered glutamate metabolism, and could explain some of the functional abnormalities that begin soon after the onset of diabetes, as early changes in electroretinogram. This review article will present some evidences that point out neurodegeneration as a possible initial event in diabetic retinopathy.

    In the area of Paripe, in the suburb of Salvador, Bahia, the distribution of electric power of the Company of Electricity of the State of Bahia (COELBA) is facing serious problems with the industrial pollution. That pollution affects the whole distribution net, causing fortuitous lack of energy, in many cases even daily in their feeders. The problem happens due to the accumulation of material associated along the net and more precisely in the distribution insulators, generating a type of dirt, no removable for normal procedures, in the surface of that insulator and it will cause escape currents, causing the lack of energy of the whole distribution electric net. The subject presented in that paper refers to the project of Research and Development (P and D), about Atmospheric Pollution in Insulators of Distribution. The results of the research showed that the atmospheric pollution could cause problems to the population that lives close the polluted area. The purpose of that article is to present relevant data related to the distribution net of COELBA, where there are many lacks of energy and the possibility of do not respect the criterion of quality of the National Agency of Electric power (ANEEL), besides the damages caused the population.

Many of them consider ACE gene could be a possible candidate to elucidate a genetic predisposition or a genetic risk factor. We aimed to examine the effects of I/D and -262A > T ACE polymorphisms in the renal function in severely ill southern Brazilians patients. A multi-organic worldwide known failure score, the SOFA (sequential organ failure assessment, was used to determine the basal health state at first day (ICU admission. Considering admission SOFA score and trend of renal function (measured by daily renal SOFA scores, with daily measure of serum creatinine and diuresis, we hypothesize that ACE polymorphisms could influence in the trend of renal function in ICU patients. A total of 153 critically ill adult patients (79 men were included in this study. We monitored the patients daily during their entire ICU and post-ICU (hospital stay (measured from the ICU admission day to a maximum of 224 days. We observed progression to renal failure (SOFA scores 3 and 4 in first seven days of ICU stay and need for dialysis. The general genotypic frequencies in our sample were II = 0.17; ID = 0.46; DD = 0.37 and AA = 0.30; AT = 0.55; TT = 0.15, and the allelic frequencies were I = 0.40; D = 0.60 and A = 0.56; T = 0.44. This is the first study to verify the influence of I/D and -262A > T ACE polymorphisms in acute renal dysfunction among critically ill patients. No significant association was found between genotypes or allele frequencies and the trend of the renal function. The I/D and -262A > T ACE polymorphisms have no significant impact on the trend of renal function during the first week of ICU stay, neither any influence in mortality in critically ill patients.

    We study the problem of locally distinguishing pure quantum states using shared entanglement as a resource. For a given set of locally indistinguishable states, we define a resource state to be useful if it can enhance local distinguishability and optimal if it can distinguish the states as well as global measurements and is also minimal with respect to a partial ordering defined by entanglement and dimension. We present examples of useful resources and show that an entangled state need not be useful for distinguishing a given set of states. We obtain optimal resources with explicit local protocols to distinguish multipartite Greenberger-Horne-Zeilinger and graph states and also show that a maximally entangled state is an optimal resource under one-way local operations and classical communication to distinguish any bipartite orthonormal basis which contains at least one entangled state of full Schmidt rank.

    We used the techniques of Electron Paramagnetic Resonance (EPR) to study the free radicals produced by X-radiation in natural crystals of Gypsum (CaSO{sub 4}2H{sub 2}0). We observed the formation of four free radicals. The spectra of these radicals are overlapped, being separated by power and temperature variation measurements. Two radicals were univocal identified, as being of OH{sup +} and 0{sub 2}H{sup +}. We suggest the assignment of SO{sub 4}{sup -} and O{sub 2}{sup -} to two other radicals. From angular variation measurements, we determined the components of tensors {r_reversible}g and {r_reversible}A of the radicals OH{sup -} and O{sub 2}H{sup -}. (author)

    The thesis describes the sweep-line method, a newly developed reduction method for alleviating the state explosion problem inherent in explicit-state state space exploration. The basic idea underlying the sweep-line method is, when calculating the state space, to recognise and delete states...... that are not reachable from the currently unprocessed states. Intuitively we drag a sweep-line through the state space with the invariant that all states behind the sweep-line have been processed and are unreachable from the states in front of the sweep-line. When calculating the state space of a system we iteratively...

    Full Text Available Constituição Federal de 1988 é um divisor de águas ao assumir-se como Constituição Ambiental, provocando uma ruptura em relação ao conceito de responsabilidade civil. Partindo de uma abordagem qualitativa, dialética e jurisprudencial, este artigo analisa o Princípio Responsabilidade desenvolvido por hans jonas e realiza um diálogo com o instituto da responsabilidade civil ambiental, identificando, com apoio na legislação constitucional e infraconstitucional, as controvérsias doutrinárias acerca da natureza da responsabilidade estatal (objetiva ou subjetiva frente a casos de omissão da administração pública e à ocorrência de dano ambiental. Conclui-se que o Superior Tribunal de Justiça assume uma dimensão mais alargada do conceito de responsabilidade civil do Estado, demonstrando uma tendência pela responsabilidade civil objetiva com base no risco. Assim, o Brasil, salvo algumas divergências doutrinárias, adota a responsabilidade civil objetiva do Estado pela teoria do risco administrativo alicerçada no ato ilícito e na aceitação do risco.The Federal Constitution of 1988 is a 'water divisor' since it assumes the role of Environmental Constitution, causing a rapture of the concept of civil liability.

    Naccache, Lionel

    2018-04-01

    Durable impairments of consciousness are currently classified in three main neurological categories: comatose state, vegetative state (also recently coined unresponsive wakefulness syndrome) and minimally conscious state. While the introduction of minimally conscious state, in 2002, was a major progress to help clinicians recognize complex non-reflexive behaviours in the absence of functional communication, it raises several problems. The most important issue related to minimally conscious state lies in its criteria: while behavioural definition of minimally conscious state lacks any direct evidence of patient's conscious content or conscious state, it includes the adjective 'conscious'. I discuss this major problem in this review and propose a novel interpretation of minimally conscious state: its criteria do not inform us about the potential residual consciousness of patients, but they do inform us with certainty about the presence of a cortically mediated state. Based on this constructive criticism review, I suggest three proposals aiming at improving the way we describe the subjective and cognitive state of non-communicating patients. In particular, I present a tentative new classification of impairments of consciousness that combines behavioural evidence with functional brain imaging data, in order to probe directly and univocally residual conscious processes.

    The paper deals with State nuclear initiatives regarding the role of nuclear power in the energy future of the United States. The question of whether and under what circumstances nuclear facilities should be used to generate electricity was put to the popular vote in several States in 1976. Some general principles of Federal-State relations are discussed with specific reference to nuclear regulations. The initiative mechanism itself is described as well as its legal form and background. The parallel developments in the State and Federal legislative consideration of nuclear issues is reviewed and the suggested reasons for the defeat of the proposals in the seven States concerned are discussed. Finally, the author draws some conclusions on the effects of the 1976 initiatives on future decision-making in the US on energy policy in general and nuclear power in particular. (NEA) [fr

    In this study, we describe a morphological biomarker that detects multiple discrete subpopulations (or "age-states") at several chronological ages in a population of nematodes (Caenorhabditis elegans). We determined the frequencies of three healthy adult states and the timing of the transitions between them across the lifespan. We used short-lived and long-lived strains to confirm the general applicability of the state classifier and to monitor state progression. This exploration revealed healthy and unhealthy states, the former being favored in long-lived strains and the latter showing delayed onset. Short-lived strains rapidly transitioned through the putative healthy state. We previously found that age-matched animals in different age-states have distinct transcriptome profiles. We isolated animals at the beginning and end of each identified state and performed microarray analysis (principal component analysis, relative sample to sample distance measurements, and gene set enrichment analysis). In some comparisons, chronologically identical individuals were farther apart than morphologically identical individuals isolated on different days. The age-state biomarker allowed assessment of aging in a novel manner, complementary to chronological age progression. We found hsp70 and some small heat shock protein genes are expressed later in adulthood, consistent with the proteostasis collapse model.

It is found that the Mie resonant state which satisfies the condition that the size parameter is less than the angular momentum should be interpreted as a photon virtual bound state. In order to confirm the validity of the concept, we compare the photonic density of states, the width of which represents the lifetime of the photon virtual bound states, with numerical results

    A proposal for a physical implementation of a quantum-state discrimination protocol using an ion in a linear trap is studied, where two nonorthogonal quantum states are codified using two electronic states of the ion. In addition, a protocol is given for discriminating superpositions of nonorthogonal entangled states between ions inside widely separated optical cavities. The discrimination protocol is extended to the case of N linearly independent nonorthogonal quantum states lying in a space of 2N-1 dimensions

  10. Verification of hypergraph states

    Hypergraph states are generalizations of graph states where controlled-Z gates on edges are replaced with generalized controlled-Z gates on hyperedges. Hypergraph states have several advantages over graph states. For example, certain hypergraph states, such as the Union Jack states, are universal resource states for measurement-based quantum computing with only Pauli measurements, while graph state measurement-based quantum computing needs non-Clifford basis measurements. Furthermore, it is impossible to classically efficiently sample measurement results on hypergraph states unless the polynomial hierarchy collapses to the third level. Although several protocols have been proposed to verify graph states with only sequential single-qubit Pauli measurements, there was no verification method for hypergraph states. In this paper, we propose a method for verifying a certain class of hypergraph states with only sequential single-qubit Pauli measurements. Importantly, no i.i.d. property of samples is assumed in our protocol: any artificial entanglement among samples cannot fool the verifier. As applications of our protocol, we consider verified blind quantum computing with hypergraph states, and quantum computational supremacy demonstrations with hypergraph states.

    1995-01-01

    Crystallized Schroedinger cat states (male and female) are introduced on the base of extension of group construction for the even and odd coherent states of the electromagnetic field oscillator. The Wigner and Q functions are calculated and some are plotted for C 2 , C 3 , C 4 , C 5 , C 3v Schroedinger cat states. Quadrature means and dispersions for these states are calculated and squeezing and correlation phenomena are studied. Photon distribution functions for these states are given explicitly and are plotted for several examples. A strong oscillatory behavior of the photon distribution function for some field amplitudes is found in the new type of states

    Passive states are defined as those states that do not allow for work extraction in a cyclic (unitary) process. Within the set of passive states, thermal states are the most stable ones: they maximize the entropy for a given energy, and similarly they minimize the energy for a given entropy. Here we find the passive states lying in the other extreme, i.e., those that maximize the energy for a given entropy, which we show also minimize the entropy when the energy is fixed. These extremal properties make these states useful to obtain fundamental bounds for the thermodynamics of finite-dimensional quantum systems, which we show in several scenarios.

  16. State diagrams of tokamaks and state transitions

    International Nuclear Information System (INIS)

    Minardi, E.

    1992-01-01

    In a simple one-fluid cylindrical model of transport and of dissipative effects, the family of the magnetic states of the Tokamak which correspond to a vanishing entropy production in the confinement region is characterized by a define relation or ''state equation'' involving the relevant parameters of the discharge. An investigation is made as to how the entropy production changes when the current density profile is rearranged by a perturbation which conserves the poloidal magnetic flux. It is shown that for a sufficiently short time interval, that is to say t 2 E τ s where τ E is the energy confinement time and τ s is the resistive time, neighbouring bifurcating equilibria exist which can be reached with a flux-conserving transition and with increase of the magnetic entropy. The family of these new states can also be characterized by a state equation involving the relevant discharge parameters. When the state equations of the two families are simultaneously satisfied by the same set of parameter values, a flux-conserving, entropy-increasing transition may take place between states of the two families. The modifications of the current density and of the temperature profiles involved in the transition and the conditions that the discharge parameters should satisfy in order that the transition could occur are investigated.

  15. Matrix product state description of Halperin states

    Crépel, V.; Estienne, B.; Bernevig, B. A.; Lecheminant, P.; Regnault, N.

    2018-04-01

    Many fractional quantum Hall states can be expressed as a correlator of a given conformal field theory used to describe their edge physics. As a consequence, these states admit an economical representation as an exact matrix product state (MPS) that was extensively studied for the systems without any spin or any other internal degrees of freedom. In that case, the correlators are built from a single electronic operator, which is primary with respect to the underlying conformal field theory. We generalize this construction to the archetype of Abelian multicomponent fractional quantum Hall wave functions, the Halperin states. These can be written as conformal blocks involving multiple electronic operators and we explicitly derive their exact MPS representation. In particular, we deal with the caveat of the full wave-function symmetry and show that any additional SU(2) symmetry is preserved by the natural MPS truncation scheme provided by the conformal dimension. We use our method to characterize the topological order of the Halperin states by extracting the topological entanglement entropy. We also evaluate their bulk correlation lengths, which are compared to plasma analogy arguments.

  16. Remote state preparation through hyperentangled atomic states

    Science.gov (United States)

    Nawaz, Mehwish; ul-Islam, Rameez-; Ikram, Manzoor

    2018-04-01

    Hyperentangled states have enhanced channel capacity in quantum processing and have yielded` evident increased communication speed in quantum informatics as a consequence of excessively high information content coded over each quantum entity. In the present article, we intend to demonstrate this fact by utilizing atomic states simultaneously entangled both in internal as well as external degrees of freedom, i.e. the de Broglie motion for remote state preparation (RSP). The results clearly demonstrate that we can efficiently communicate two bit information while manipulating only a single quantum subsystem. The states are prepared and manipulated using atomic Bragg diffraction as well as Ramsey interferometry, both of which are now considered as standard, state of the art tools based on cavity quantum electrodynamics. Since atomic Bragg diffraction is a large interaction time regime and produces spatially well separated, decoherence resistant outputs, the schematics presented here for the RSP offer important perspectives on efficient detection as well as unambiguous information coding and readout. The article summarizes the experimental feasibility of the proposal, culminating with a brief discussion.

  17. Quantum states of light

    CERN Document Server

    Furusawa, Akira

    2015-01-01

    This book explains what quantum states of light look like. Of special interest, a single photon state is explained by using a wave picture, showing that it corresponds to the complementarity of a quantum. Also explained is how light waves are created by photons, again corresponding to the complementarity of a quantum. The author shows how an optical wave is created by superposition of a "vacuum" and a single photon as a typical example. Moreover, squeezed states of light are explained as "longitudinal" waves of light and Schrödinger's cat states as macroscopic superposition states.

  18. Symmetries of Chimera States

    Science.gov (United States)

    Kemeth, Felix P.; Haugland, Sindre W.; Krischer, Katharina

    2018-05-01

    Symmetry broken states arise naturally in oscillatory networks. In this Letter, we investigate chaotic attractors in an ensemble of four mean-coupled Stuart-Landau oscillators with two oscillators being synchronized. We report that these states with partially broken symmetry, so-called chimera states, have different setwise symmetries in the incoherent oscillators, and in particular, some are and some are not invariant under a permutation symmetry on average. This allows for a classification of different chimera states in small networks. We conclude our report with a discussion of related states in spatially extended systems, which seem to inherit the symmetry properties of their counterparts in small networks.

  19. Generalized hypergeometric coherent states

    International Nuclear Information System (INIS)

    Appl, Thomas; Schiller, Diethard H

    2004-01-01

    We introduce a large class of holomorphic quantum states by choosing their normalization functions to be given by generalized hypergeometric functions. We call them generalized hypergeometric states in general, and generalized hypergeometric coherent states in particular, if they allow a resolution of unity. Depending on the domain of convergence of the generalized hypergeometric functions, we distinguish generalized hypergeometric states on the plane, the open unit disc and the unit circle. All states are eigenstates of suitably defined lowering operators. We then study their photon number statistics and phase properties as revealed by the Husimi and Pegg-Barnett phase distributions. On the basis of the generalized hypergeometric coherent states we introduce new analytic representations of arbitrary quantum states in Bargmann and Hardy spaces as well as generalized hypergeometric Husimi distributions and corresponding phase distributions

    1990-01-01

    The report addresses the nature and major features of molecule's superexcited states, focusing on their involvement in dynamic processes. It also outlines the quantum defect theory which allows various processes involving these states to be treated in a unified way. The Rydberg state has close relation with an ionized state with a positive energy. The quantum defect theory interprets such relation. Specifically, the report first describes the quantum defect theory focusing on its basic principle. The multi-channel quantum defect theory is then outlined centering on how to describe a Rydberg-type superexcited state. Description of a dissociative double-electron excited state is also discussed. The quantum defect theory is based on the fact that the physics of the motion of a Rydberg electron vary with the region in the electron's coordinate space. Finally, various molecular processes that involve a superexcited state are addressed focusing on autoionization, photoionization, dissociative recombination and bonding ionization of diatomic molecules.

  1. Qutrit magic state distillation

    International Nuclear Information System (INIS)

    Anwar, Hussain; Browne, Dan E; Campbell, Earl T

    2012-01-01

    Magic state distillation (MSD) is a purification protocol that plays an important role in fault-tolerant quantum computation. Repeated iteration of the steps of an MSD protocol generates pure single non-stabilizer states, or magic states, from multiple copies of a mixed resource state using stabilizer operations only. Thus mixed resource states promote the stabilizer operations to full universality. MSD was introduced for qubit-based quantum computation, but little has been known concerning MSD in higher-dimensional qudit-based computation. Here, we describe a general approach for studying MSD in higher dimensions. We use it to investigate the features of a qutrit MSD protocol based on the five-qutrit stabilizer code. We show that this protocol distils non-stabilizer magic states, and identify two types of states that are attractors of this iteration map. Finally, we show how these states may be converted, via stabilizer circuits alone, into a state suitable for state-injected implementation of a non-Clifford phase gate, enabling non-Clifford unitary computation.

    2012-01-30

    The U. S. Department of Energy (DOE), National Association of State Energy Officials (NASEO), and Association of State Energy Research and Technology Transfer Institutions (ASERTTI) signed an intergovernmental agreement on November 14, 2002, that allowed states and territories and the Federal Government to better collaborate on energy research, development, demonstration and deployment (RDD&D) projects. The agreement established the State Technologies Advancement Collaborative (STAC) which allowed the states and DOE to move RDD&D forward using an innovative competitive project selection and funding process. A cooperative agreement between DOE and NASEO served as the contracting instrument for this innovative federal-state partnership obligating funds from DOE's Office of Energy Efficiency and Renewable Energy and Office of Fossil Energy to plan, fund, and implement RDD&D projects that were consistent with the common priorities of the states and DOE. DOE's Golden Field Office provided Federal oversight and guidance for the STAC cooperative agreement. The STAC program was built on the foundation of prior Federal-State efforts to collaborate on and engage in joint planning for RDD&D. Although STAC builds on existing, successful programs, it is important to note that it was not intended to replace other successful joint DOE/State initiatives such as the State Energy Program or EERE Special Projects. Overall the STAC process was used to fund, through three competitive solicitations, 35 successful multi-state research, development, deployment, and demonstration projects with an overall average non-federal cost share of 43%. Twenty-two states were awarded at least one prime contract, and organizations in all 50 states and some territories were involved as subcontractors in at least one STAC project. Projects were funded in seven program areas: (1) Building Technologies, (2) Industrial Technologies, (3) Transportation Technologies, (4) Distributed Energy

All participants signed an informed consent form. The micronuclei technique (MN was used, which blocks cytokinesis in peripheral blood samples, to evaluate GD by counting the number of MN and Chromatin Bridges in 1000 bi-nucleated cells (BNC. The results of this measure of genetic damage were then correlated with the degree of occupational pesticide exposure of the participants. Environmentally exposed men had less GD than women with MN means of 8.1± (1.83 and 13.1(±1.7 respectively, whereas occupational exposure affected both sexes, men with a mean of MN equal to 15.9 (± 2.9, and women with 18.12 (± 1.7. Based on our results, it can be concluded that occupational exposure to pesticides is a factor in GD, with women showing greater vulnerability than men. The time of exposure at work was shown to be directly related to the increased number of MN.Diferentes estudos mostram a capacidade que os pesticidas possuem para induzir dano genético (DG com diversos efeitos na saúde.

    The quantum interference between the two parts of the optical Schrodinger-cat state makes possible to construct a wide class of quantum states via discrete superpositions of coherent states. Even a small number of coherent states can approximate the given quantum states at a high accuracy when the distance between the coherent states is optimized, e. g. nearly perfect Fock state can be constructed by discrete superpositions of n + 1 coherent states lying in the vicinity of the vacuum state.

    We study a theoretical model of closed quasi-hermitian chain of spins which exhibits quantum analogues of chimera states, i.e. long life classical states for which a part of an oscillator chain presents an ordered dynamics whereas another part presents a disordered dynamics. For the quantum analogue, the chimera behaviour deals with the entanglement between the spins of the chain. We discuss the entanglement properties, quantum chaos, quantum disorder and semi-classical similarity of our quantum chimera system. The quantum chimera concept is novel and induces new perspectives concerning the entanglement of multipartite systems. - Highlights: • We propose a spin chain model with long range couplings having purely quantum states similar to the classical chimera states. • The quantum chimera states are characterized by the coexistence of strongly entangled and non-entangled spins in the same chain. • The quantum chimera states present some characteristics of quantum chaos.

    We review clustering in light nuclei including molecular resonances in heavy ion reactions. In particular we study the systematics, paying special attention to the relationships between cluster states and superdeformed configurations. We emphasise the selection rules which govern the formation and decay of cluster states. We review some recent experimental results from Daresbury and elsewhere. In particular we report on the evidence for a 7-α chain state in 28 Si in experiments recently performed at the NSF, Daresbury. Finally we begin to address theoretically the important question of the lifetimes of cluster states as deduced from the experimental energy widths of the resonances. (Author)

    Ambruş, Victor E.; Winstanley, Elizabeth

    2014-01-01

    We revisit the definition of rotating thermal states for scalar and fermion fields in unbounded Minkowski space–time. For scalar fields such states are ill-defined everywhere, but for fermion fields an appropriate definition of the vacuum gives thermal states regular inside the speed-of-light surface. For a massless fermion field, we derive analytic expressions for the thermal expectation values of the fermion current and stress–energy tensor. These expressions may provide qualitative insights into the behaviour of thermal rotating states on more complex space–time geometries

  17. Maximally multipartite entangled states

    Science.gov (United States)

    Facchi, Paolo; Florio, Giuseppe; Parisi, Giorgio; Pascazio, Saverio

    2008-06-01

    We introduce the notion of maximally multipartite entangled states of n qubits as a generalization of the bipartite case. These pure states have a bipartite entanglement that does not depend on the bipartition and is maximal for all possible bipartitions. They are solutions of a minimization problem. Examples for small n are investigated, both analytically and numerically.

  18. States in Process Calculi

    Directory of Open Access Journals (Sweden)

    Christoph Wagner

    2014-08-01

    Full Text Available Formal reasoning about distributed algorithms (like Consensus typically requires to analyze global states in a traditional state-based style. This is in contrast to the traditional action-based reasoning of process calculi. Nevertheless, we use domain-specific variants of the latter, as they are convenient modeling languages in which the local code of processes can be programmed explicitly, with the local state information usually managed via parameter lists of process constants. However, domain-specific process calculi are often equipped with (unlabeled reduction semantics, building upon a rich and convenient notion of structural congruence. Unfortunately, the price for this convenience is that the analysis is cumbersome: the set of reachable states is modulo structural congruence, and the processes' state information is very hard to identify. We extract from congruence classes of reachable states individual state-informative representatives that we supply with a proper formal semantics. As a result, we can now freely switch between the process calculus terms and their representatives, and we can use the stateful representatives to perform assertional reasoning on process calculus models.

  4. Dissociative State and Competence

    2007-10-01

    Full Text Available This report presents the results of forensic evaluation of the civil competence of a case of alleged dissociative identity disorder (DID and discusses whether such dissociative states substantially jeopardize civil competence. A 40-year-old woman claimed that she had had many personalities since her college days. From the age of 37 to 40, she shopped excessively, which left her with millions of dollars of debt. She ascribed her shopping to a certain identity state, over which she had no control. (In this article, we use the term identity state to replace personality as an objective description of a mental state. She thus raised the petition of civil incompetence. During the forensic evaluation, it was found that the identity states were relatively stable and mutually aware of each other. The switch into another identity state was sometimes under voluntary control. The subject showed consistency and continuity in behavioral patterns across the different identity states, and no matter which identity state she was in, there was no evidence of impairment in her factual knowledge of social situations and her capacity for managing personal affairs. We hence concluded that she was civilly competent despite the claimed DID. Considering that the existence and diagnosis of DID are still under dispute and a diagnosis of DID alone is not sufficient to interdict a person's civil right, important clinical and forensic issues remain to be answered.

    International Nuclear Information System (INIS)

    1989-07-01

    Pursuant to the Hazardous Materials Transportation Act (HMTA), the Department of Transportation (DOT) has promulgated a comprehensive set of regulations regarding the highway transportation of high-level radioactive materials. These regulations, under HM-164 and HM-164A, establish interstate highways as the preferred routes for the transportation of radioactive materials within and through the states. The regulations also provide a methodology by which a state may select alternative routes. First,the state must establish a ''state routing agency,'' defined as an entity authorized to use the state legal process to impose routing requirements on carriers of radioactive material (49 CFR 171.8). Once identified, the state routing agency must select routes in accordance with Large Quantity Shipments of Radioactive Materials or an equivalent routing analysis. Adjoining states and localities should be consulted on the impact of proposed alternative routes as a prerequisite of final route selection. Lastly, the states must provide written notice of DOT of any alternative route designation before the routes are deemed effective

  12. Categorical Tensor Network States

    2011-12-01

    Full Text Available We examine the use of string diagrams and the mathematics of category theory in the description of quantum states by tensor networks. This approach lead to a unification of several ideas, as well as several results and methods that have not previously appeared in either side of the literature. Our approach enabled the development of a tensor network framework allowing a solution to the quantum decomposition problem which has several appealing features. Specifically, given an n-body quantum state |ψ〉, we present a new and general method to factor |ψ〉 into a tensor network of clearly defined building blocks. We use the solution to expose a previously unknown and large class of quantum states which we prove can be sampled efficiently and exactly. This general framework of categorical tensor network states, where a combination of generic and algebraically defined tensors appear, enhances the theory of tensor network states.

    Full Text Available The debate about the relationship between state and market, about their relative importance, does not cease to be topical, and there is no end of it in sight. The market (invisible hand does need, more or less, the help of the state (visible hand. Liberal sympathizers of the market prefer a “small” state whose ambitions include only providing an adaptable legal framework in which and by which the market functions, and (re allocation of resources, because of the inherent defects of the market. Proponents of welfare economics will wish for progressive taxation and redistribution of income. Keynes’s mission to save capitalism meant an increase in the importance of the state and appearance of a new, stabilizing role of the state. Excessive unemployment is to be prevented by fine-tuning. Unfortunately, Keynes’s critics from the public choice camp will say that the state (government is not perfect, and, as a rule, falls into the trap of asymmetry. Only and solely in theory will it apply that a perfect state means perfect functioning of an imperfect market.

    Werner states are paradigmatic examples of quantum states and play an innovative role in quantum information theory. In investigating the correlating capability of Werner states, we find the curious phenomenon that quantum correlations, as quantified by the entanglement of formation, may exceed the total correlations, as measured by the quantum mutual information. Consequently, though the entanglement of formation is so widely used in quantifying entanglement, it cannot be interpreted as a consistent measure of quantum correlations per se if we accept the folklore that total correlations are measured (or rather upper bounded) by the quantum mutual information.

    Han, Yingying; Zhang, Jun; Zhang, Wenxian

    2018-04-01

    Phenomena of electromagnetically induced transparency (PEIT) may be interpreted by the Autler-Townes Splitting (ATS), where the coupled states are split by the coupling laser field, or by the quantum destructive interference (QDI), where the atomic phases caused by the coupling laser and the probe laser field cancel. We propose modulated experiments to explore the PEIT in an alternative way by periodically modulating the coupling and the probe fields in a Λ-type three-level system initially in a dark state. Our analytical and numerical results rule out the ATS interpretation and show that the QDI interpretation is more appropriate for the modulated experiments. Interestingly, dark state persists in the double-modulation situation where control and probe fields never occur simultaneously, which is significant difference from the traditional dark state condition. The proposed experiments are readily implemented in atomic gases, artificial atoms in superconducting quantum devices, or three-level meta-atoms in meta-materials.

    CERN Document Server

    Fujimoto, Minoru

    2010-01-01

    Thermodynamics is a well-established discipline of physics for properties of matter in thermal equilibrium surroundings. Applying to crystals, however, the laws encounter undefined properties of crystal lattices, which therefore need to be determined for a clear and well-defined description of crystalline states. Thermodynamics of Crystalline States explores the roles played by order variables and dynamic lattices in crystals in a wholly new way. This book is divided into three parts. The book begins by clarifying basic concepts for stable crystals. Next, binary phase transitions are discussed to study collective motion of order variables, as described mostly as classical phenomena. In the third part, the multi-electron system is discussed theoretically, as a quantum-mechanical example, for the superconducting state in metallic crystals. Throughout the book, the role played by the lattice is emphasized and examined in-depth. Thermodynamics of Crystalline States is an introductory treatise and textbook on meso...

Várias espécies de fungos foram associadas ao cancro observado no campo, mais notavelmente Lasiodiplodia theobromae e Pestalotiopsis sp. Culturas isoladas destes fungos, frequentemente associados a outros (incluindo Fusarium oxysporum, Alternaria e basidiomicetes, foram testadas quanto à patogenicidade em plantas jovens de paricá, com aproximadamente um metro de altura. Apenas L. theobromae produziu cancro sob as condições testadas, quando discos de cultura foram aplicados usando técnicas de inoculação por ferimento e alta umidade, reproduzindo perfeitamente os sintomas do campo. Pestalotiopsis sp. causou danos muito menores quando comparado a L. theobromae. A confirmação de L. theobromae como agente causal do cancro em paricá ocorreu após o reisolamento do fungo a partir dos tecidos sintomáticos das plantas inoculadas em casa-de-vegetação, concluindo a verificação dos Postulados de Koch.

    A large thrust earthquake (Mw=7.6) occurred on January 30, 1973, on the plate interface between the subducting Cocos plate and the continental North America plate, near the triple junction between the North America, Cocos and Rivera Plates. This event might be related to two sequences of subsequent large earthquakes that occurred around this region. Although several authors have analyzed the focal mechanism and depth of this earthquake, we analyzed its source characteristics and performed a linear kinematic waveform inversion for the slip distribution over the fault plane. We find a shallow thrust mechanism (St=285 degrees, Dip=16 degrees, Ra=85 degrees) consistent with the tectonic environment, with a depth of 16 km and a total moment release of 2.98x10{sup 2}7 dyn-cm. The results show a slip distribution with two main patches, with a maximum dislocation of 199 cm and 173 cm respectively. We calculated the coseismic stress change on and around the fault plane. This earthquake ruptured two main asperities, one downdip and southwest and the other updip and northwest of the hypocenter, with stress change of -31 and -40 bars respectively The surrounding zone of stress increase could have influenced the subsequent seismicity to a distance of up to 120 km from the hypocenter. [Spanish] El 30 de enero de 1973 ocurrio un evento mayor de subduccion (Mw=7.6) en la interfase de las placas de Cocos y Norteamerica, cerca del punto triple entre las placas de Rivera, Cocos y Norteamerica. Este evento podria estar relacionado con dos secuencias de grandes sismos subsecuentes que ocurrieron alrededor de esta region. Aunque varios autores han analizado el mecanismo focal y la profundidad de este sismo, nosotros analizamos las caracteristicas de la fuente y realizamos una inversion cinematica lineal de la distribucion de deslizamientos sobre el plano de falla a traves del modelado de forma de onda. Encontramos un mecanismo inverso (St=285 grados, Dip=16 grados, Ra=85 grados) consistente con la tectonica regional, con una profundidad de 16 km y una liberacion total de momento de 2.98x10{sup 2}7 dyn-cm. Los resultados muestran una distribucion de deslizamiento con dos manchas principales, con una dislocacion maxima de 199 cm y 173 cm respectivamente. Calculamos el cambio del esfuerzo cosismico en y alrededor del plano de falla. Este sismo rompio dos asperezas principales en el plano de falla extendido: una en la parte inferior y al suroeste y la otra en la parte superior y al noroeste del hipocentro, con un cambio de esfuerzos de -31 y -40 bars respectivamente. El area circundante de incremento de esfuerzo podria haber influenciado la sismicidad subsecuente a una distancia de hasta 120 km del hipocentro.

  13. Waterbirds and human-related threats to their conservation in Laguna Cuyutlán, Colima, México

    2009-06-01

    Full Text Available Laguna Cuyutlán, the only large wetland in a span of 1 150 km along the Pacific coast of México, has been neglected as to its importance for waterbird conservation. At least 25 waterbird species nest there, with some of their colonies being very relevant, and at least 61 waterbird species use the lagoon during their nonbreeding season. This lagoon has been subject to several structural modifications, including levees and artificial channels which connect it to the sea, while water supply from continental sources has diminished, although its role has not been assessed yet. Salt extraction and artisanal fishery, the main economic activities, do not seem to pose a threat to waterbirds. Among potential threats to this acquatic ecosystem, are the raw sewage discharges that exist near urban areas, and pesticides from the surrounding agricultural lands might reach the lagoon. Seemingly, the most serious threat comes from waterway development in connection with a re-gasification plant to be built, and planned future port expansion, which could potentially increase water levels and alter important habitats for nesting and foraging. We recommend that: the area be declared an Important Bird Area; the development of the re-gasification plant and future port includes a levee to prevent alterations in water level in the remaining sections of the lagoon; supply of exogenous chemicals and waste products be prevented and monitored; alleged benefits from water interchange between the lagoon and the sea through artificial channels should be re-evaluated; and the role of fresh water supplies to the lagoon should be paid attention to. Rev. Biol. Trop. 57 (1-2: 1-12. Epub 2009 June 30.Laguna Cuyutlán, el único humedal grande a lo largo de 1 150 km del Pacífico mexicano, no ha sido considerado un ecosistema natural importante para la conservación de aves acuáticas. Cuando menos 25 especies de aves acuáticas anidan ahí, y al menos 61 especies de aves acuáticas la usan fuera de la temporada reproductiva. Esta laguna ha sufrido varias modificaciones estructurales, y el aporte de agua dulce ha disminuido, sin que se conozcan sus consecuencias. La extracción de sal y la pesca artesanal, las principales actividades económicas, no parecen ser riesgo para las aves acuáticas. Entre los riesgos potenciales, están las aguas negras cerca de zonas urbanas y los plaguicidas de zonas agrícolas colindantes. Aparentemente, el riesgo más serio deriva del desarrollo marítimo asociado con una planta regasificadora a construirse pronto, y del desarrollo portuario futuro, que podrían incrementar los niveles de agua en la laguna y alterar los hábitats de las aves acuáticas. Recomendamos que: el área se declare como AICA; el desarrollo futuro incluya un dique para prevenir alteraciones en el nivel del agua en el resto de la laguna; el aporte de sustancias agroquímicas y aguas negras se monitoree; se reevalúen los supuestos beneficios del intercambio de agua entre la laguna y el mar por medio de canales artificiales; y se investigue científicamente los aportes de agua dulce a la laguna.

  15. State responses to biotechnology.

    Harris, Rebecca C

    2015-01-01

    This article reviews biotechnology legislation in the 50 states for 11 policy areas spanning 1990-2010, an era of immense growth in biotechnology, genetic knowledge, and significant policy development. Policies regarding health insurance, life insurance, long-term care insurance, DNA data bank collection, biotech research protection, biotech promotion and support, employment discrimination, genetic counselor licensing, human cloning, and genetic privacy each represent major policy responses arising from biotechnology and coinciding with key areas of state regulation (insurance, criminal justice, economic development, labor law, health and safety, privacy, and property rights). This analysis seeks to answer three questions regarding biotechnology legislation at the state level: who is acting (policy adoption), when is policy adopted (policy timing), and what is policy doing (policy content). Theoretical concerns examine state ideology (conservative or liberal), policy type (economic or moral), and the role of external events (federal law, news events, etc.) on state policy adoption. Findings suggest ideological patterns in adoption, timing, and content of biotech policy. Findings also suggest economic policies tend to be more uniform in content than moral policies, and findings also document a clear link between federal policy development, external events, and state policy response.

    In relativistic quantum theory, bound states generate forces in the crossed channel; such forces can affect the binding and self-consistent solutions should be sought for the bound-state problem. The author investigates how self-consistency can be achieved by successive approximations, in a simple scalar model and with successive relativistic eikonal approximations (EAs). Within the generalized ladder approximation, some exact properties of the resulting ''first generation'' bound states are discussed. The binding energies in this approximation are rather small even for rather large values of the primary coupling constant. The coupling of the constituent particles to the first-generation reggeon is determined by a suitable EA and a new generalized ladder amplitude is constructed with rungs given either by the primary gluons or by the first-generation reggeons. The resulting new (second-generation) bound states are found in a reggeized EA. The size of the corrections to the binding energies due to the rebinding effects is surprisingly large. The procedure is then iterated, so as to find - again in an EA - the third-generation bound states. The procedure is found to be self-consistent already at this stage: the third-generation bound states coincide with those of second generation, and no further rebinding takes place in the higher iterations of the approximation method. Features - good and bad - of the model are discussed, as well as the possible relevance of rebinding mechanisms in hadron dynamics. (author)

    Artificial neural networks and machine learning have now reached a new era after several decades of improvement where applications are to explode in many fields of science, industry, and technology. Here, we use artificial neural networks to study an intriguing phenomenon in quantum physics—the topological phases of matter. We find that certain topological states, either symmetry-protected or with intrinsic topological order, can be represented with classical artificial neural networks. This is demonstrated by using three concrete spin systems, the one-dimensional (1D) symmetry-protected topological cluster state and the 2D and 3D toric code states with intrinsic topological orders. For all three cases, we show rigorously that the topological ground states can be represented by short-range neural networks in an exact and efficient fashion—the required number of hidden neurons is as small as the number of physical spins and the number of parameters scales only linearly with the system size. For the 2D toric-code model, we find that the proposed short-range neural networks can describe the excited states with Abelian anyons and their nontrivial mutual statistics as well. In addition, by using reinforcement learning we show that neural networks are capable of finding the topological ground states of nonintegrable Hamiltonians with strong interactions and studying their topological phase transitions. Our results demonstrate explicitly the exceptional power of neural networks in describing topological quantum states, and at the same time provide valuable guidance to machine learning of topological phases in generic lattice models.

    A scheme of teleportation of a tripartite state via W state is suggested. The W state serves as quantum channels. Standard Bell-state measurements and Von Neumann measurements are performed. After the sender operates the measurements and informs the receiver her results, he can reconstruct the original state by the corresponding unitary transformation. The probability of the successful teleportation is also obtained.

    Chimera states are self-organized spatiotemporal patterns of coexisting coherence and incoherence. We give an overview of the main mathematical methods used in studies of chimera states, focusing on chimera states in spatially extended coupled oscillator systems. We discuss the continuum limit approach to these states, Ott-Antonsen manifold reduction, finite size chimera states, control of chimera states and the influence of system design on the type of chimera state that is observed.

    By considering the quantum-mechanically minimum allowable energy interval, we exactly count number of states (NOS) and introduce discrete density of states (DOS) concept for a particle in a box for various dimensions. Expressions for bounded and unbounded continua are analytically recovered from discrete ones. Even though substantial fluctuations prevail in discrete DOS, they're almost completely flattened out after summation or integration operation. It's seen that relative errors of analytical expressions of bounded/unbounded continua rapidly decrease for high NOS values (weak confinement or high energy conditions), while the proposed analytical expressions based on Weyl's conjecture always preserve their lower error characteristic. - Highlights: • Discrete density of states considering minimum energy difference is proposed. • Analytical DOS and NOS formulas based on Weyl conjecture are given. • Discrete DOS and NOS functions are examined for various dimensions. • Relative errors of analytical formulas are much better than the conventional ones.

    We demonstrate that chimera behavior can be observed in small networks consisting of three identical oscillators, with mutual all-to-all coupling. Three different types of chimeras, characterized by the coexistence of two coherent oscillators and one incoherent oscillator (i.e., rotating with another frequency) have been identified, where the oscillators show periodic (two types) and chaotic (one type) behaviors. Typical bifurcations at the transitions from full synchronization to chimera states and between different types of chimeras have been described. Parameter regions for the chimera states are obtained in the form of Arnold tongues, issued from a singular parameter point. Our analysis suggests that chimera states can be observed in small networks relevant to various real-world systems.

    The State Manager system (SM) is a set of tools, developed at CERN, for the control of large data-acquisition systems. A dedicated object-based language is used to describe the various components of the data-acquisition system. Each component is declared in terms of finite state machines and sequences of parametrized actions to be performed for operations such as the start and end of a run. The description, written by the user, is translated into Ada to produce a run-control program capable of controlling processes in a distributed environment. A Motif-based graphical interface to the control program displays the current state of all the components and can be used to control the overall data-acquisition system. The SM has been used by several experiments both at CERN and other organizations. We present here the architecture of the SM, some design choices, and the experience acquired from its use. (author)

  7. The association between state attachment security and state Mindfulness.

    Directory of Open Access Journals (Sweden)

    Christopher A Pepping

    Full Text Available Recent research suggests that attachment and mindfulness are related, though the nature of this association is unclear. Here we present two studies examining whether there is a causal relationship between state attachment and state mindfulness. Study 1 investigated the effects of experimentally increasing state mindfulness on state attachment security. State mindfulness was successfully enhanced, but this led to no change in state attachment security. Study 2 investigated the effects of experimentally enhancing state attachment security on state mindfulness. State attachment security was successfully enhanced, but this did not lead to any change in state mindfulness. These findings suggest that there is not a direct, immediate causal relationship between state attachment and state mindfulness as a result of brief experimental manipulations. Future research should examine these associations in longer term interventions.

    Lind, P.

    1993-02-01

    The completeness properties of the discrete set of bound state, virtual states and resonances characterizing the system of a single nonrelativistic particle moving in a central cutoff potential is investigated. From a completeness relation in terms of these discrete states and complex scattering states one can derive several Resonant State Expansions (RSE). It is interesting to obtain purely discrete expansion which, if valid, would significantly simplify the treatment of the continuum. Such expansions can be derived using Mittag-Leffler (ML) theory for a cutoff potential and it would be nice to see if one can obtain the same expansions starting from an eigenfunction theory that is not restricted to a finite sphere. The RSE of Greens functions is especially important, e.g. in the continuum RPA (CRPA) method of treating giant resonances in nuclear physics. The convergence of RSE is studied in simple cases using square well wavefunctions in order to achieve high numerical accuracy. Several expansions can be derived from each other by using the theory of analytic functions and one can the see how to obtain a natural discretization of the continuum. Since the resonance wavefunctions are oscillating with an exponentially increasing amplitude, and therefore have to be interpreted through some regularization procedure, every statement made about quantities involving such states is checked by numerical calculations.Realistic nuclear wavefunctions, generated by a Wood-Saxon potential, are used to test also the usefulness of RSE in a realistic nuclear calculation. There are some fundamental differences between different symmetries of the integral contour that defines the continuum in RSE. One kind of symmetry is necessary to have an expansion of the unity operator that is idempotent. Another symmetry must be used if we want purely discrete expansions. These are found to be of the same form as given by ML. (29 refs.)

    Graphene is locally two-dimensional but not flat. Nanoscale ripples appear in suspended samples and rolling up often occurs when boundaries are not fixed. We address this variety of graphene geometries by classifying all ground-state deformations of the hexagonal lattice with respect to configurational energies including two- and three-body terms. As a consequence, we prove that all ground-state deformations are either periodic in one direction, as in the case of ripples, or rolled up, as in the case of nanotubes.

    In order to employ Molecular Dynamics method, commonly used in condensed matter physics, we have derived the equations of motion for a beam of charged particles in the rotating rest frame of the reference particle. We include in the formalism that the particles are confined by the guiding and focusing magnetic fields, and that they are confined in a conducting vacuum pipe while interacting with each other via a Coulomb force. Numerical simulations has been performed to obtain the equilibrium structure. The effects of the shearing force, centrifugal force, and azimuthal variation of the focusing strength are investigated. It is found that a constant gradient storage ring can not give a crystalline beam, but that an alternating-gradient (AG) structure can. In such a machine the ground state is, except for one-dimensional (1-D) crystals, time-dependent. The ground state is a zero entropy state, despite the time-dependent, periodic variation of the focusing force. The nature of the ground state, similar to that found by Rahman and Schiffer, depends upon the density and the relative focusing strengths in the transverse directions. At low density, the crystal is 1-D. As the density increases, it transforms into various kinds of 2-D and 3-D crystals. If the energy of the beam is higher than the transition energy of the machine, the crystalline structure can not be formed for lack of radial focusing

  13. Crystalline beam ground state

    International Nuclear Information System (INIS)

    Wei, J.; Li, X.P.

    1993-01-01

    In order to employ the Molecular Dynamics method, commonly used in condensed matter physics, the authors have derived the equations of motion for a beam of charged particles in the rotating rest frame of the reference particle. They include in the formalism that the particles are confined by the guiding and focusing magnetic fields, and that they are confined in a conducting vacuum pipe while interacting with each other via a Coulomb force. Numerical simulations has been performed to obtain the equilibrium structure. The effects of the shearing force, centrifugal force, and azimuthal variation of the focusing strength are investigated. It is found that a constant gradient storage ring can not give a crystalline beam, but that an alternating-gradient (AG) structure can. In such a machine the ground state is, except for one-dimensional (1-D) crystals, time-dependent. The ground state is a zero entropy state, despite the time-dependent, periodic variation of the focusing force. The nature of the ground state, similar to that found by Rahman and Schiffer, depends upon the density and the relative focusing strengths in the transverse directions. At low density, the crystal is 1-D. As the density increases, it transforms into various kinds of 2-D and 3-D crystals. If the energy of the beam is higher than the transition energy of the machine, the crystalline structure can not be formed for lack of radial focusing

  8. Understanding the pointer states

    International Nuclear Information System (INIS)

    Alexandre Brasil, Carlos; Andreta de Castro, Leonardo

    2015-01-01

    In quantum mechanics, pointer states are eigenstates of the observable of the measurement apparatus that represent the possible positions of the display pointer of the equipment. The origin of this concept lies in attempts to fill the blanks in Everett’s relative-state interpretation, and to make it a fully valid description of physical reality. To achieve this, it was necessary to consider not only the main system interacting with the measurement apparatus (like von Neumann and Everett did) but also the role of the environment in eliminating correlations between different possible measurements when interacting with the measurement apparatus. The interaction of the environment with the main system (and the measurement apparatus) is the core of the decoherence theory, which followed Everett’s thesis. In this article, we review the measurement process according to von Neumann, Everett’s relative state interpretation, the purpose of decoherence and some of its follow-up until Wojciech Zurek’s primordial paper that consolidated the concept of pointer states, previously presented by Heinz Dieter Zeh. Employing a simple physical model consisting of a pair of two-level systems—one representing the main system, the other the measurement apparatus—and a thermal bath—representing the environment—we show how pointer states emerge, explaining its contributions to the question of measurement in quantum mechanics, as well as its limitations. Finally, we briefly show some of its consequences. This paper is accessible to readers with elementary knowledge about quantum mechanics, on the level of graduate courses. (paper)

  9. Paired Hall states

    International Nuclear Information System (INIS)

    Greiter, M.

    1992-01-01

    This dissertation contains a collection of individual articles on various topics. Their significance in the corresponding field as well as connections between them are emphasized in a general and comprehensive introduction. In the first article, the author explores the consequences for macroscopic effective Lagrangians of assuming that the momentum density is proportional to the flow of conserved current. The universal corrections obtained for the macroscopic Lagrangian of a superconductor describe the London Hall effect, and provide a fully consistent derivation of it. In the second article, a heuristic principle is proposed for quantized Hall states: the existence and incompressibility of fractionally quantized Hall states is explained by an argument based on an adiabatic localization of magnetic flux, the process of trading uniform flux for an equal amount of fictitious flux attached to the particles. This principle is exactly implemented in the third article. For a certain class of model Hamiltonians, the author obtains Laughlin's Jastrow type wave functions explicitly from a filled Landau level, by smooth extrapolation in quantum statistics. The generalization of this analysis to the torus geometry shows that theorems restricting the possibilities of quantum statistics on closed surfaces are circumvented in the presence of a magnetic field. In the last article, the existence is proposed of a novel incompressible quantum liquid, a paired Hall state, at a half filled Landau level. This state arises adiabatically from free fermions in zero magnetic field, and reduces to a state previously proposed by Halperin in the limit of tightly bound pairs. It supports unusual excitations, including neutral fermions and charge e/4 anyons with statistical parameter θ = π/8

  10. Coherent states and rational surfaces

    International Nuclear Information System (INIS)

    Brody, Dorje C; Graefe, Eva-Maria

    2010-01-01

    The state spaces of generalized coherent states associated with special unitary groups are shown to form rational curves and surfaces in the space of pure states. These curves and surfaces are generated by the various Veronese embeddings of the underlying state space into higher dimensional state spaces. This construction is applied to the parameterization of generalized coherent states, which is useful for practical calculations, and provides an elementary combinatorial approach to the geometry of the coherent state space. The results are extended to Hilbert spaces with indefinite inner products, leading to the introduction of a new kind of generalized coherent states.

    Lithium aluminates proposed to the production of tritium in fusion nuclear reactors, due to the thermal stability that they present as well as the behavior of the aluminium to the irradiation. As a neutron flux with profile ({approx_equal} 14 Mev) of a fusion reactor is not available. A irradiation experiment was designed in order to know the micro and nano structure damages produced by fast and thermal neutrons in two irradiation positions of the fusion nuclear reactor Triga Mark III: CT (Thermal Column) and SIFCA (System of Irradiation Fixed of Capsules). In this work samples of lithium aluminate were characterized by XRD (X-Ray Diffraction), TEM (Transmission Electron Microscopy) and SEM (Scanning Electron Microscopy). Two samples were prepared by two methods: a) coalition method and b) peroxide method. This characterization comprised original and irradiated samples. The irradiated sample amounted to 4 in total: one for each preparation method and one for each irradiation position. The object of this analysis was to correlate with the received neutron dose the damages suffered by the samples with the neutron irradiation during long periods (440 H), in their micro and nano structure aspects; in order to understand the changes as a function of the irradiation zone (with thermal and fast neutron flux) and the preparation methods of the samples and having as an antecedent the irradiation in SIFCA position by short times (2h). The obtained results are referred to the stability of {gamma} -aluminate phase, under given conditions of irradiation and defined nano structure arrangement. They also refer to the proposals of growth mechanism and nucleation of new phases. The error associated with the measurement of neutron dose is also discussed. (Author)

    Samples containing PPO (1%, g/ml), diluted in toluene, they were irradiated in a {sup 60}Co irradiator (6.46 kGy/h) at different doses. The PPO concentration decay bi-exponentially with the dose, generating the degradation products: benzoic acid, benzamide and benzilic alcohol. The liquid scintillator system was not sensitive to the radiation damage until 20 kGy. Otherwise, the pulse height analysis showed that dose among 30 to 40 kGy generate significant loss of quality of the sensor (liquid scintillating) and the light yield was reduced in half with the dose of (34.04 {+-} 0.80) kGy. This value practically was confirmed by the photo peak position analysis that resulted D{sub 1/2} = (31.7 {+-} 1,4) kGy, The transmittance, at 360 nm, of the irradiated solution decreased exponentially. The compartmental model using five compartments (fast decay PPO, slow decay PPO, benzamide, benzoic acid and benzilic alcohol) it was satisfactory to explain the decay of the PPO in its degradation products in function of the dose. The explanation coefficient r{sup 2} = 0.985636 assures that the model was capable to explain 98.6% of the experimental variations. The Target Theory together with the Compartmental Analysis showed that PPO irradiated in toluene solution presents two sensitive molecular diameters both of them larger than the true PPO diameter. >From this analysis it showed that the radiolytic are generated, comparatively, at four toluene molecules diameter far from PPO molecules. For each one PPO-target it was calculated the G parameter (damage/100 eV). For the target expressed by the fast decay the G value was (418.4 {+-} 54.1) damages/100 eV, and for the slow decay target the G value was (54.5 {+-} 8.9) damages/100 eV. The energies involved in the chemical reactions were w (0.239 {+-} 0.031) eV/damage (fast decay) and w = (1 834 {+-} 0.301) eV/damage (slow decay). (author)

    2007-01-01

    Quantum optical Gaussian states are a type of important robust quantum states which are manipulatable by the existing technologies. So far, most of the important quantum information experiments are done with such states, including bright Gaussian light and weak Gaussian light. Extending the existing results of quantum information with discrete quantum states to the case of continuous variable quantum states is an interesting theoretical job. The quantum Gaussian states play a central role in such a case. We review the properties and applications of Gaussian states in quantum information with emphasis on the fundamental concepts, the calculation techniques and the effects of imperfections of the real-life experimental setups. Topics here include the elementary properties of Gaussian states and relevant quantum information device, entanglement-based quantum tasks such as quantum teleportation, quantum cryptography with weak and strong Gaussian states and the quantum channel capacity, mathematical theory of quantum entanglement and state estimation for Gaussian states

    The multi-valley effective mass formalism for the asymmetric energy surfaces developed in an earlier paper is extended for the calculations of the ground state energies of isocoric donors in Ge. The impurity potential is constructed from the k-dependent dielectric function of Ge and a variational trial wave function, belonging to an irreducible representation of the point group Tsub(d) of the Hamiltonian, is used. The calculated energy levels for the singlet A 1 and the triplet T 2 symmetries of the ls states for As in Ge is found to be of the same order (-9.6 to-12.8 meV) as observed experimentally; however, the predicted E(A 1 ) - E(T 2 ) splitting is rather too small (approximately -0.5 to -0.7 meV) compared with the observed value -4.23 meV

    Cutting states associated with the orthogonal cutting of stiff cylinders are identified through an analysis of the singular values of a Toeplitz matrix of third order cumulants of acceleration measurements. The ratio of the two pairs of largest singular values is shown to differentiate between light cutting, medium cutting, pre-chatter and chatter states. Sequences of cutting experiments were performed in which either depth of cut or turning frequency was varied. Two sequences of experiments with variable turning frequency and five with variable depth of cut, 42 cutting experiments in all, provided a database for the calculation of third order cumulants. Ratios of singular values of cumulant matrices find application in the analysis of control of orthogonal cutting

  5. Thermodynamics of Crystalline States

    CERN Document Server

    Fujimoto, Minoru

    2013-01-01

    Thermodynamics is a well-established discipline of physics for properties of matter in thermal equilibrium with the surroundings. Applying to crystals, however, the laws encounter undefined properties of crystal lattice, which therefore need to be determined for a clear and well-defined description of crystalline states. Thermodynamics of Crystalline States explores the roles played by order variables and dynamic lattices in crystals in a wholly new way. The book begins by clarifying basic concepts for stable crystals. Next, binary phase transitions are discussed to study collective motion of order variables, as described mostly as classical phenomena. New to this edition is the examination of magnetic crystals, where magnetic symmetry is essential for magnetic phase transitions. The multi-electron system is also discussed  theoretically, as a quantum-mechanical example, for superconductivity in metallic crystals. Throughout the book, the role played by the lattice is emphasized and studied in-depth. Thermod...

  6. Parallel Polarization State Generation.

    Science.gov (United States)

    She, Alan; Capasso, Federico

    2016-05-17

    The control of polarization, an essential property of light, is of wide scientific and technological interest. The general problem of generating arbitrary time-varying states of polarization (SOP) has always been mathematically formulated by a series of linear transformations, i.e. a product of matrices, imposing a serial architecture. Here we show a parallel architecture described by a sum of matrices. The theory is experimentally demonstrated by modulating spatially-separated polarization components of a laser using a digital micromirror device that are subsequently beam combined. This method greatly expands the parameter space for engineering devices that control polarization. Consequently, performance characteristics, such as speed, stability, and spectral range, are entirely dictated by the technologies of optical intensity modulation, including absorption, reflection, emission, and scattering. This opens up important prospects for polarization state generation (PSG) with unique performance characteristics with applications in spectroscopic ellipsometry, spectropolarimetry, communications, imaging, and security.

    Lipkin, H.J.

    1986-01-01

    The success of simple constituent quark models in single-hardon physics and their failure in multiquark physics is discussed, emphasizing the relation between meson and baryon spectra, hidden color and the color matrix, breakup decay modes, coupled channels, and hadron-hadron interactions via flipping and tunneling of flux tubes. Model-independent predictions for possible multiquark bound states are considered and the most promising candidates suggested. A quark approach to baryon-baryon interactions is discussed

    2013-01-01

    Full Text Available Following the stages from the establishment itself to the present day of the functioning of such a specific regional organization as the Commonwealth of Independent States (CIS, the article seeks to further explain the meaning of its existence, efficiency and functioning. The CIS was created in order to make the dissolution of a major world super-power, which throughout the 20th century together with the USA defined the bipolar world, as painless as possible, especially for the new countries and its nationally and ethnically diverse population. During the early years after the dissolution of the USSR, the CIS played a major role in a more flexible and less severe dissolution of the Soviet empire, alleviating the consequences for its people. A more efficient functioning among the republics in all fields was also one of the tasks of the Commonwealth, to which it was devoted to the extent which was permitted by the then, not too favourable circumstances. Difficult years of economic crisis did not allow the CIS to mutually integrate its members as much as possible on the economy level. Thanks to the economic recovery of the post-Soviet states in the early 21st century, the Commonwealth has also been transformed, reformed, and renewed, and all this in order to achieve better and more fruitful cooperation between the members. The CIS may serve as a proper example of how the former Soviet Union states are inextricably linked by social, security-political, economic, cultural, communication-transport, and other ties, thanks to the centuries-long existence of the peoples of these states in this area, despite both internal and external factors which occasionally, but temporarily halt the post-Soviet integration. Mathematically expressed, the CIS members are naturally predisposed, to be reciprocally depended on each other, just as they also have the capacity for successful cooperation in the future times and epochs brought on by the modern world.

    The deformation-driving effects of intruder states are studied by analysis of various types of data on rotational bands in rare-earth deformed nuclei. The sensitivity of four measurables (bandhead energy, B(E2) value, neutron i{sub 13/2} crossing frequency, and signature splitting) to increased deformation in an intruder band is shown. The analysis of signature splitting systematics is extended to known superdeformed bands. (author). 22 refs., 5 figs.

    A definition of the coherent state representation is given in this paper. In the representation quantum theory equations take the form of classical field theory equations (with causality inherent to the latter) not only in simple cases (free field and interactions with an external current or field), but also in the general case of closed systems of interacting fields. And, conversely, a classical field theory can be transformed into a form of a quantum one

    Roberts, M.

    2003-01-01

    Upon pressure from the United States Congress, the US Department of Energy had to withdraw from further American participation in the ITER Engineering Design Activities after the end of its commitment to the EDA in July 1998. In the years since that time, changes have taken place in both the ITER activity and the US fusion community's position on burning plasma physics. Reflecting the interest in the United States in pursuing burning plasma physics, the DOE's Office of Science commissioned three studies as part of its examination of the option of entering the Negotiations on the Agreement on the Establishment of the International Fusion Energy Organization for the Joint Implementation of the ITER Project. These were a National Academy Review Panel Report supporting the burning plasma mission; a Fusion Energy Sciences Advisory Committee (FESAC) report confirming the role of ITER in achieving fusion power production, and The Lehman Review of the ITER project costing and project management processes (for the latter one, see ITER CTA Newsletter, no. 15, December 2002). All three studies have endorsed the US return to the ITER activities. This historical decision was announced by DOE Secretary Abraham during his remarks to employees of the Department's Princeton Plasma Physics Laboratory. The United States will be working with the other Participants in the ITER Negotiations on the Agreement and is preparing to participate in the ITA

  20. Variational transition state theory

    International Nuclear Information System (INIS)

    Truhlar, D.G.

    1986-01-01

    This project is concerned with the development and applications of generalized transition state theory and multidimensional tunneling approximations to chemical reaction rates. They have developed and implemented several practical versions of variational transition state theory (VTST), namely canonical variational theory (CVT), improved canonical variational theory (ICVT), and microcanonical variational theory (μVT). They have also developed and implemented several accurate multidimensional semiclassical tunneling approximations, the most accurate of which are the small-curvature semiclassical adiabatic (SCSA), large-curvature version-3 (LC3), and least-action (LA) approximations. They have applied the methods to thermal rate constants, using transmission coefficients based on ground-state tunneling, and they have also presented and applied adiabatic and diabatic extensions to calculated rate constants for vibrationally excited reactants. Their general goal is to develop accurate methods for calculating chemical reaction rate constants that remain practical even for reasonably complicated molecules. The approximations mentioned above yield rate constants for systems whose potential energy surface is known or assumed. Thus a second, equally important aspect of their work is the determination or modeling, semi-empirically and/or from electronic structure calculations, of potential energy surfaces

  1. JWL Equation of State

    Energy Technology Data Exchange (ETDEWEB)

    Menikoff, Ralph [Los Alamos National Laboratory

    2015-12-15

    The JWL equation of state (EOS) is frequently used for the products (and sometimes reactants) of a high explosive (HE). Here we review and systematically derive important properties. The JWL EOS is of the Mie-Grueneisen form with a constant Grueneisen coefficient and a constants specific heat. It is thermodynamically consistent to specify the temperature at a reference state. However, increasing the reference state temperature restricts the EOS domain in the (V, e)-plane of phase space. The restrictions are due to the conditions that P ≥ 0, T ≥ 0, and the isothermal bulk modulus is positive. Typically, this limits the low temperature regime in expansion. The domain restrictions can result in the P-T equilibrium EOS of a partly burned HE failing to have a solution in some cases. For application to HE, the heat of detonation is discussed. Example JWL parameters for an HE, both products and reactions, are used to illustrate the restrictions on the domain of the EOS.

  2. Deep inelastic final states

    International Nuclear Information System (INIS)

    Girardi, G.

    1980-11-01

    In these lectures we attempt to describe the final states of deep inelastic scattering as given by QCD. In the first section we shall briefly comment on the parton model and give the main properties of decay functions which are of interest for the study of semi-inclusive leptoproduction. The second section is devoted to the QCD approach to single hadron leptoproduction. First we recall basic facts on QCD log's and derive after that the evolution equations for the fragmentation functions. For this purpose we make a short detour in e + e - annihilation. The rest of the section is a study of the factorization of long distance effects associated with the initial and final states. We then show how when one includes next to leading QCD corrections one induces factorization breaking and describe the double moments useful for testing such effects. The next section contains a review on the QCD jets in the hadronic final state. We begin by introducing the notion of infrared safe variable and defining a few useful examples. Distributions in these variables are studied to first order in QCD, with some comments on the resummation of logs encountered in higher orders. Finally the last section is a 'gaullimaufry' of jet studies

    1994-01-01

    The device of the present invention conducts information processing suitable for a man to solve a problem in a plant such as a nuclear power plant incorporating a great amount of information, where safety is required and provides information to an operator. Namely, theories and rules with respect to the flow and balanced state of materials and energy upon plant start-up, and a vapor cycle of operation fluids are symbolized and displayed on the display screen of the device. Then, the display of the plant information suitable to the information processing for a man to dissolve problems is provided. Accordingly, a mechanism for analyzing a purpose of the plant is made more definite, thereby enabling to prevent an erroneous judgement of an operator and occurrence of plant troubles. In addition, a simular effect can also be expected when the theories and rules with respect to the flow and the balanced state of materials and energy and thermohydrodynamic behavior of the operation fluids in a state of after-heat removing operation during shutdown of the plant are symbolized and displayed.

    2008-07-01

    Full Text Available Landauer’s principle is applied to information in the universe. Once stars began forming there was a constant information energy density as the increasing proportion of matter at high stellar temperatures exactly compensated for the expanding universe. The information equation of state was close to the dark energy value, w = -1, for a wide range of redshifts, 10 > z > 0.8, over one half of cosmic time. A reasonable universe information bit content of only 1087 bits is sufficient for information energy to account for all dark energy. A time varying equation of state with a direct link between dark energy and matter, and linked to star formation in particular, is clearly relevant to the cosmic coincidence problem. In answering the ‘Why now?’ question we wonder ‘What next?’ as we expect the information equation of state to tend towards w = 0 in the future.c

  5. United States advanced technologies

    1985-01-01

    In the United States, the advanced technologies have been applied to uranium enrichment as a means by which it can be assured that nuclear fuel cost will remain competitive in the future. The United States is strongly committed to the development of advanced enrichment technology, and has brought both advanced gas centrifuge (AGC) and atomic vapor laser isotope separation (AVLIS) programs to a point of significant technical refinement. The ability to deploy advanced technologies is the basis for the confidence in competitive future price. Unfortunately, the development of advanced technologies is capital intensive. The year 1985 is the key year for advanced technology development in the United States, since the decision on the primary enrichment technology for the future, AGC or AVLIS, will be made shortly. The background on the technology selection process, the highlights of AGC and AVLIS programs and the way to proceed after the process selection are described. The key objective is to maximize the sales volume and minimize the operating cost. This will help the utilities in other countries supply low cost energy on a reliable, long term basis. (Kako, I.)

    Partial Néel states are generalizations of the ordinary Néel (classical anti-ferromagnet) state that can have arbitrary integer spin. We study overlaps of these states with Bethe states. We first identify this overlap with a partial version of reflecting-boundary domain-wall partition function, and then derive various determinant representations for off-shell and on-shell Bethe states.

    2015-04-01

    Full Text Available A new functional state, namely dissolved oxygen limitation state for both bacteria Escherichia coli and yeast Saccharomyces cerevisiae fed-batch cultivation processes is presented in this study. Functional state modelling approach is applied to cultivation processes in order to overcome the main disadvantages of using global process model, namely complex model structure and a big number of model parameters. Alongwith the newly introduced dissolved oxygen limitation state, second acetate production state and first acetate production state are recognized during the fed-batch cultivation of E. coli, while mixed oxidative state and first ethanol production state are recognized during the fed-batch cultivation of S. cerevisiae. For all mentioned above functional states both structural and parameter identification is here performed based on experimental data of E. coli and S. cerevisiae fed-batch cultivations.

  9. Teleportations of Mixed States and Multipartite Quantum States

    Institute of Scientific and Technical Information of China (English)

    YU Chang-Shui; WANG Ya-Hong; SONG He-Shan

    2007-01-01

    In this paper, we propose a protocol to deterministically teleport an unknown mixed state of qubit by utilizing a maximally bipartite entangled state of qubits as quantum channel. Ifa non-maximally entangled bipartite pure state is employed as quantum channel, the unknown mixed quantum state of qubit can be teleported with 1 - √1 - C2 probability, where C is the concurrence of the quantum channel. The protocol can also be generalized to teleport a mixed state of qudit or a multipartite mixed state. More important purpose is that, on the basis of the protocol, the teleportation of an arbitrary multipartite (pure or mixed) quantum state can be decomposed into the teleportation of each subsystem by employing separate entangled states as quantum channels. In the case of deterministic teleportation,Bob only needs to perform unitary transformations on his single particles in order to recover the initial teleported multipartite quantum state.

    Art, R.J.

    1991-01-01

    This paper reports that at least in the national security arena, the outcomes of bureaucratic infighting and domestic political struggles are not determined wholly by what goes on with the state. Rather struggles among contending groups are greatly affected by what is perceived to be happening outside the nation. Because external conditions give greater potency to some domestic forces over other, the external environment is never neutral in its domestic impact. The decisions of the period 1950-53 discussed above illustrate the point. But so too do the decisions of 1947, 1960-61 and 1969-72. In the 1947 case, Soviet intransigence provoked US nuclear rearmament. In the 1960-61 case, extended deterrent considerations pushed the United States to preserve its again newly discovered nuclear superiority. In the 1969-72 case, a Soviet determination to remain equal forced US acceptance of nuclear equality. And perhaps the best evidence of all, the perpetuation of parity ended the US inclination to resort to nuclear brinkmanship. In each instance, concerns about relative position heavily affected nuclear choice. Finally, the events of the past three years testify to the effects of international events on domestic choice. Under the terms of the 1987 INF Treaty, the two superpowers decided to dismantle and destroy an entire class of missiles of intermediate range (500-3000 kilometers) that both had deployed in Europe in the 1970s and 1980s, and in their June 1990 joint statement on strategic nuclear weapons, President Gorbachev and Brush agreed to cut the number of Soviet and US long range nuclear forces by 30 per cent. This agreement marks a watershed in US-Soviet strategic arm negotiations because for the first time the United States and the Soviet Union agreed in principals to reduce the number of weapons aimed at one another. Between 1985 and 1990 the cold war was brought to a close

    2007-01-01

    The US Senate consented to the ratification of the Convention on Supplementary Compensation for Nuclear Damage (CSC) on 4 August 2006. The entry into force of the Convention on Supplementary Compensation will substantially change the face of the international nuclear liability regime. The CSC is a free-standing instrument, open to all states. This means that countries can become party to a new global regime providing for liability and compensation for victims of a nuclear incident, without also having to become a contracting party to the Paris Convention or the Vienna Convention. This is certainly a major step forward given that at the present time, over half of the world's reactors in operation or under construction are not covered by any of the international nuclear third party liability conventions. The CSC creates an instrument by which states can ensure that more money will be made available to compensate more victims for a broader range of damage than ever before. The CSC provides for two tiers of compensation. The first tier, fixed at 300 million Special Drawing Rights, is to be provided by the liable operator. This tier is to be distributed on a non-discriminatory basis to victims both inside and outside of the Installation State. If 300 million SDRs are insufficient to compensate all damage, then contracting parties will be required to contribute to the second tier (the international fund). The amount of this second tier is not fixed, but rather will depend on the number of operating nuclear power plants in contracting parties, and is designed to increase as the number of such plants increases

    The effects of polarization on the stability of α-cluster structures in 8 Be and 12 C nuclei are studied in the intrinsic states. The extent of the polarization of α-clusters is investigated by employing a molecular-orbital model. Two α-cluster structure of 8 Be is shown to be extremely stable, and a triangular configuration of three α-clusters is also shown to be stable, but the polarizations of α-clusters are found rather large. Gruemmer--Faessler's method is discussed and their results are shown to be trivial

    Direct electrochemical storage of electricity is attractive because of its adaptability to vehicle traction as well as to stationary applications. Important advancements are necessary to improve primary or secondary batteries so far used. The aim of this study was to develop and to characterize materials for the next generation of advanced, rechargeable solid state batteries for vehicle transport and stationary storage applications. One of the best electricity storage systems was the lithium/intercalation compound secondary battery, though up to now the behavior of liquid organic electrolytes did not allow for good recycling in such systems. The research program for these batteries is described.
