    I estimate the aggregate income elasticity of Wal-Mart's and Target's revenues using quarterly data for 1997-2006. I find that Wal-Mart's revenues increase during bad times, whereas Target's revenues decrease, consistent with Wal-Mart selling "inferior goods" in the technical sense of the term. An upper bound on the aggregate income elasticity of demand for Wal-Mart's wares is -0.5.

    2005-01-01

    Full Text Available La misión astrobiológica más importante que se ha realizado hasta la fecha ha sido sin duda el proyecto Vikingo de la NASA. Esta misión consistió en tres experimentos biológicos especialmente diseñados para la búsqueda de indicadores de vida en las capas superficiales del suelo marciano. Los tres experimentos dieron resultados positivos. Sin embargo, el análisis de materia orgánica en el suelo marciano demostró la ausencia total de carbono orgánico. Este hallazgo fue utilizado como uno de los argumentos más sólidos en contra de la existencia de vida en la superficie del planeta Marte. Como preparación para futuras misiones a Marte en búsqueda de vida es necesario probar los instrumentos en localidades terrestres que pudieran ser ambientes análogos a Marte. Uno de los desiertos más áridos del planeta es el de Atacama, en el norte de Chile. Estudios químicos y microbiológicos del suelo de Atacama sugieren que el corazón del desierto es en realidad un buen análogo de Marte, ya que no posee vida macroscópica y microscópica, tiene niveles muy bajos de materia orgánica, y sus suelos son muy reactivos. En colaboración con científicos franceses y estadounidenses, estamos preparando una misión robótica dirigida por la NASA para la búsqueda de vida pasada o presente en Marte por lo que el Desierto de Atacama en Chile es el escenario para la preparación de esta misión espacial.

    Highlights: Black-Right-Pointing-Pointer We show that the MARTe is a candidate for ITER PSH. Black-Right-Pointing-Pointer We replace the old real-time feedback software using the MARTe framework. Black-Right-Pointing-Pointer We describe all the work done for the integration. - Abstract: Keeping in mind the necessities of a modern control system for fusion devices, such as modularity and a distributed architecture, an upgrade of the present FTU feedback control system was planned, envisaging also a possible reutilization in the proposed FAST experiment [1]. For standardization and efficiency purposes we decided to adopt a pre-existent ITER-relevant framework called MARTe [2], already used with success in other European Tokamak devices [3]. Following the developments shown in [4], in this paper we report on the structure of the new feedback system, and how it was integrated in the current control structure and pulse programming interface, and in the other MARTe systems already in FTU: RT-ODIN [5] and the ECRH and LH [6] satellite stations. The new feedback system has been installed in the FTU backup station (known as 'Feedback B'), which shares the input signals with the actual feedback system, in order to simplify the validation and debug of the new controller by testing it in parallel with the current one. Experimental results are then presented.

    Development of real-time applications is usually associated with nonportable code targeted at specific real-time operating systems. The boundary between hardware drivers, system services, and user code is commonly not well defined, making the development in the target host significantly difficult. The Multithreaded Application Real-Time executor (MARTe) is a framework built over a multiplatform library that allows the execution of the same code in different operating systems. The framework provides the high-level interfaces with hardware, external configuration programs, and user interfaces, assuring at the same time hard real-time performances. End-users of the framework are required to define and implement algorithms inside a well-defined block of software, named Generic Application Module (GAM), that is executed by the real-time scheduler. Each GAM is reconfigurable with a set of predefined configuration meta-parameters and interchanges information using a set of data pipes that are provided as inputs and required as output. Using these connections, different GAMs can be chained either in series or parallel. GAMs can be developed and debugged in a non-real-time system and, only once the robustness of the code and correctness of the algorithm are verified, deployed to the real-time system. The software also supplies a large set of utilities that greatly ease the interaction and debugging of a running system. Among the most useful are a highly efficient real-time logger, HTTP introspection of real-time objects, and HTTP remote configuration. MARTe is currently being used to successfully drive the plasma vertical stabilization controller on the largest magnetic confinement fusion device in the world, with a control loop cycle of 50 ?s and a jitter under 1 ?s. In this particular project, MARTe is used with the Real-Time Application Interface (RTAI)/Linux operating system exploiting the new ?86 multicore processors technology.

    Full Text Available The objectives of this study was the physical, chemical, and physiological characterization of marolo (Annona crassiflora, Mart. during its development. The fruits were harvested 12 Km off Itumirim, Southern Minas Gerais, Brazil, at 20-d intervals from anthesis to fruit maturity. The first fruits were harvested within 60 days. The total development of the fruit took 140 days starting from anthesis. At 140 days after anthesis, the fruit reached its maximum size, with mass of 1.380g, transverse diameter of 13.0 cm, and longitudinal diameter of 11.5 cm. During its development, the fruit showed increase in mass and in traverse and longitudinal diameters. The changes during maturation and ripening, such as: pH reduction and starch degradation, pectic solubilization, and increase in total sugars, soluble solids (ºB, respiratory rate (CO2, titratable acidity, vitamin C, and β-caroteno were observed from the 120th day of marolo development. A decrease in ability to sequester free radicals was observed up the 120th day, followed by an increase. The volatile compounds identified at the end of the development included the esters group only.

    Full Text Available La martora, Martes martes, è un mustelide storicamente presente su gran parte del territorio italiano, soprattutto dove siano presenti foreste mature altamente strutturate e ricche di risorse. Nel corso dei decenni passati, cause quali la deforestazione con conseguente frammentazione dell'habitat, la caccia e la persecuzione da parte dell'uomo hanno portato ad un sensibile declino sia nel numero d'individui sia di popolazioni in tutta l'Europa. Frammentazione degli areali e diminuzione del numero di soggetti costituiscono le cause principali di un limitato flusso genico con conseguente formazione di popolazioni isolate di martora e perdita di variabilità genetica (Kyle et al., 2003. Per queste ragioni la martora risulta attualmente tutelata secondo quanto previsto dalla Convenzione di Berna (appendice III e dalla Direttiva europea 92/43/CEE "Habitats & Species". Di fronte a prospettive di tipo conservazionistico, diventa necessario disporre di metodologie per la valutazione della variabilità residua nella specie a livello d'individui e di popolazioni. Secondo numerosi Autori, i microsatelliti costituiscono marcatori molto efficaci nella descrizione della struttura genetica e della storia demografica di specie (Beaumont & Bruford, 1999; Linares, 1999. Il presente lavoro propone i risultati ottenuti attraverso il confronto di due campioni costituiti da individui di Martes martes provenienti dalla Sardegna (25 esemplari e dal territorio italiano (6 esemplari. L'analisi è stata condotta a livello di 7 loci microsatellitari dinucleotidici polimorfici. Il valore di FST calcolato dal confronto dei due gruppi è risultato pari a 0,102 e ricade nel range di variazione identificato di recente in popolazioni nord-europee di martora (Kyle et al., 2003. L'analisi della varianza molecolare (AMOVA, condotta a due livelli gerarchici, ha permesso in particolare di ripartire la varianza del campione

    Market power in the competitive electric marketplace will depend on being a low-price leader. Electric utility executives are beginning to peer over the wall into the emerging world of competitive electric markets. Many will be terrified by the uncertainties and disorder associated with new service offerings such as retail wheeling and the transformation of other vestiges of the vertically integrated electric monopolies known for the past 100 years. The potential for increased competition for retail customers promises to have as fundamental an effect on the electric utility industry as Wal-Mart has had on retailing. Firms that are prepared for the new competitive environment will be in the strongest position to respond to the marketplace; those that are not prepared might want to consider the fate of the corner five-and-dime. To remain competitive, utility executives must take proactive steps to redefine their vision of their company's future. Such a redefinition must include a candid assessment of the strategies to be taken to reposition their firm to succeed, not just within the existing service area but in multiple markets

    Validation by means of simulation is a crucial step when developing real-time control systems. Modeling and simulation are an essential tool since the early design phase, when the control algorithms are designed and tested. This phase is commonly carried out in off-line environments such as Matlab and Simulink. A MARTe-based simulator has been recently developed to validate the new JET Vertical Stabilization (VS) system. MARTe is the multi-thread framework used at JET to deploy hard real-time control systems. This paper presents the software architecture of the MARTe-based simulator and it shows how this tool has been effectively used to evaluate the effects of Edge Localized Modes (ELMs) on the VS system. By using the simulator it is possible to analyze different plasma configurations, extrapolating the limit of the new vertical amplifier in terms of the energy of the largest rejectable ELM.

    Full Text Available Pneumatophores of Mauritia vinifera Mart. were collected from six month-old plants maintained submerged in fresh water to induce pneumatophore formation. Twenty day-old pneumatophores had a quite prominent root cap. The epidermis was composed of hexagonal cells, tangentially distributed along the cylindric surface of the organ. In transverse section these pneumatophores had a simple epidermis over several layers of sclerified parenchyma, which covered an aerenchyma with large intercellular spaces. The endodermal cells had Casparian strips. The vascular cylinder was polyarch, with a pith and surrounded by a unisseriate pericycle. Anatomically the 4 month-old pneumatophores were similar to the younger ones, except for the absence of the epidermis. The epidermis is replaced by a protective tissue, whose lignified and suberized cells projected themselves outwards, giving it a filamentous aspect. There was no accumulation of starch or tannins in the pneumatophores, except for the presence of statoliths in the root cap. No lenticels were observed in pneumatophores of M. vinifera. The main function of the pneumatophores of M. vinifera is to allow gas exchange, facilitating the supply of oxygen to the submerged root portions.Pneumatóforos de Mauritia vinifera Mart. foram coletados de plantas com seis meses de idade mantidas submersas em água com o objetivo de induzir a formação de pneumatóforos.

  3. La historia orbital de Deimos y la oblicuidad de Marte

    Science.gov (United States)

    Brunini, A.; Yokoyama, T.

    Recientemente, se ha demostrado mediante extensas integraciones numéricas, que la rotación de Marte pasó repetidamente por estados caóticos de movimiento, debido al pasaje por zonas de resonancia spin - órbita. En dichas circunstancias, la oblicuidad marciana pudo haber sufrido grandes excursiones de varias decenas de grados. Las consecuencias de dichas variaciones son de extrema importancia en el contexto de la búsqueda de manifestaciones de vida fósil en dicho planeta. El estudio de la dinámica orbital del satélite más exterior de Marte, Deimos, nos ha permitido comprobar, en el marco de las distintas teorías sobre su orígen, que la oblicuidad de Marte dificilmente pudo haber sufrido variaciones que la aparten más de 10o respecto de actual valor. Este resultado parece ser mucho más robusto que las simulaciones numéricas de Touma y Wisdom asi como las de Laskar y Robutel, lo que permite poner cotas más severas a la evolución paleoclimática de Marte.

    Science.gov (United States)

    Pan, Jun; Huang, Haiguang; Liu, Yousong

    A novel data mart based system for fishery rescue field was designed and implemented. The system runs ETL process to deal with original data from various databases and data warehouses, and then reorganized the data into the fishery rescue data mart. Next, online analytical processing (OLAP) are carried out and statistical reports are generated automatically. Particularly, quick configuration schemes are designed to configure query dimensions and OLAP data sets. The configuration file will be transformed into statistic interfaces automatically through a wizard-style process. The system provides various forms of reporting files, including crystal reports, flash graphical reports, and two-dimensional data grids. In addition, a wizard style interface was designed to guide users customizing inquiry processes, making it possible for nontechnical staffs to access customized reports. Characterized by quick configuration, safeness and flexibility, the system has been successfully applied in city fishery rescue department.

    2010-01-01

    Full Text Available The purpose of this paper is to critically review some of the main theoretical tenets in Ezequiel Martínez Estrada’s pessimistic stance about the Argentinean history and society of his time. Focusing on his critical remarks about the so-called «literatura o poesía gauchesca» as well as on his enthusiastic assessment of José Hernández’ Martín Fierro, the achievements and missing points in Martínez Estrada’s skeptical diagnosis will be underlined and put in broader philosophical context. For the Argentinean writer the controversial notion of a “superimposed reality” – as he infers its existence from the Martín Fierro – captures a kind of ambivalent metaphysical concurrence among the literary creation, the geographical setting and the sociopolitical state of the country.

    2015-11-01

    Full Text Available Nuestro José Martí, ejemplo de una formación humanística integral, escribió en una carta a María Mantilla:”Donde yo encuentro poesía mayor es en los libros de ciencia…” Martí vio la ciencia como un fenómeno social y consideró que el desarrollo científico técnico debía estar en función de la satisfacción de las necesidades de las grandes mayorías. Su sistemática voluntad  de cultivarse, de tratar de entender al mundo y no sólo de vivirlo, de razonarlo, fue el motor principal que llevaría a Martí a hacerse de una cultura científica y técnica poco común entre los hombres de su época. También el hecho de vivir durante muchos años en los Estados Unidos le permitió analizar con  profundidad y realismo la sociedad de la época, y por tanto llegó a tener una visión muy avanzada de la relación hombre – naturaleza - sociedad, llegando a convertirse en un gran divulgador de los avances de la ciencia y la técnica de aquella época. La originalidad del periodismo de nuevo tipo que inicia José Martí como vehículo para la divulgación científico - técnica encuentra una de sus más altas expresiones en la revista “La América”. Esta publicación había comenzado en abril de 1882, en Nueva York, bajo la dirección de Rafael de Castro Palomino, quien solicita la colaboración del poeta. A partir del mes de marzo de 1883, el Maestro redacta “La América” en su totalidad, desde los titulares hasta los artículos ensayísticos. Martí caracteriza “La América” como “periódico útil”, pues se dedicó a divulgar los adelantos de la industria, comercio y agricultura de los productores de la América del Norte, y en el avisador prudente de los compradores de la América del Sur. Este carácter de la publicación permite a José Martí tratar desde las páginas de “La América” los recientes descubrimientos científicos, la reseña detallada de las exposiciones que exhibían los últimos logros de la t

    Full Text Available Kielmeyera coriacea Mart., known as “pau-santo”, is mentioned in the literature as the main tree species which produces cork of the Brazilian Cerrado. The purpose of this study was to describe the morphological aspect of Kielmeyera coriacea (“pau-santo” cork cells through its microscopic structure and to compare it with the cellular morphology of Quercus suber (cork oak, which is the main cork producing species worldwide. The bark from three trees of the species Kielmeyera coriacea Mart. was collected randomly at points 1.30 m above the ground, with four repetitions per sample. Samples came from native stands situated in the region of Luminárias - MG, Brazil. The study of morphological characteristics was conducted by counting the number of sides of the cells, and measuring the dimensions of the cells from images obtained by scanning electron microscopy (SEM. Images were analyzed using the LEOUIF software. The distribution in faces and edges of cork cells from Kielmeyera coriacea, was observed to have from 4 to 8 sides, with a predominance of hexagonal cells, similar to Quercus suber. The averages of height and thickness of the cell walls were 40 to 70 µm and 1.5 to 2.0 µm respectively, indicating cells from an early growth season. Both height and thickness were observed to be greater than those present in Quercus suber

    Matsakis, Nicholas D.; Gross, Thomas R.

    Intervals are a new, higher-level primitive for parallel programming with which programmers directly construct the program schedule. Programs using intervals can be statically analyzed to ensure that they do not deadlock or contain data races. In this paper, we demonstrate the flexibility of intervals by showing how to use them to emulate common parallel control-flow constructs like barriers and signals, as well as higher-level patterns such as bounded-buffer producer-consumer. We have implemented intervals as a publicly available library for Java and Scala.

    Full Text Available Nearly 230 species of biting midges have been recorded or described from Argentina; 38 of them are known from the Buenos Aires province and only one is cited from Martín García Island. This paper presents the results raised from six collecting trips which took place on the island during spring 2005, summer 2006 and autumn 2009. Diverse sampling sites including permanent and temporary aquatic environments were chosen, most of the ten sampling sites were ponds of diverse origin, some of these environments were covered with floating vegetation as Lemna gibba, Lemna minuscule, Salvinia biloba, Salvinia minima, Azolla filiculoides, Limnobium laevigatum, Pistia stratiotes, Spirodela intermedia, Wolffiella oblonga and Wolffia columbiana. Other sites were placed in urban and suburban areas. Adults were collected with sweep nets at sunrise and sunset and with light traps at intervals of four to five hours at night, depending on electricity availability on the island. Larvae and pupae were collected with different implements depending on characteristics of each surveyed aquatic habitat. In free standing water, they were captured with small sieves or hand pipettes and micropipettes, flotation techniques were utilized for sampling vegetated areas, free and rooted floating hydrophytes were extracted for removing insects among them. Thirteen species of Ceratopogonidae were collected, three of Atrichopogon Kieffer, three of Forcipomyia Meigen, two of Dasyhelea Kieffer, four of Culicoides Latreille, and one of Bezzia Kieffer, all representing new records from the island.

  8. Motion tracking-enhanced MART for tomographic PIV

    International Nuclear Information System (INIS)

    Novara, Matteo; Scarano, Fulvio; Batenburg, Kees Joost

    2010-01-01

    A novel technique to increase the accuracy of multiplicative algebraic reconstruction technique (MART) reconstruction from tomographic particle image velocimetry (PIV) recordings at higher seeding density than currently possible is presented. The motion tracking enhancement (MTE) method is based on the combined utilization of images from two or more exposures to enhance the reconstruction of individual intensity fields. The working principle is first introduced qualitatively, and the mathematical background is given that explains how the MART reconstruction can be improved on the basis of an improved first guess object obtained from the combination of non-simultaneous views reduced to the same time instant deforming the 3D objects by an estimate of the particle motion field. The performances of MTE are quantitatively evaluated by numerical simulation of the imaging, reconstruction and image correlation processes. The cases of two or more exposures obtained from time-resolved experiments are considered. The iterative application of MTE appears to significantly improve the reconstruction quality, first by decreasing the intensity of the ghost images and second, by increasing the intensity and the reconstruction precision for the actual particles. Based on computer simulations, the maximum imaged seeding density that can be dealt with is tripled with respect to the MART analysis applied to a single exposure. The analysis also illustrates that the maximum effect of the MTE method is comparable to that of doubling the number of cameras in the tomographic system. Experiments performed on a transitional jet at Re = 5000 apply the MTE method to double-frame recordings. The velocity measurement precision is increased for a system with fewer views (two or three cameras compared with four cameras). The ghost particles' intensity is also visibly reduced although to a lesser extent with respect to the computer simulations. The velocity and vorticity field obtained from a three

    Decoction of roots of the Amazonian palm acai (Euterpe precatoria Mart.) is widely used by Brazilian and Peruvian people as an anti-inflammatory, to heal kidney and liver diseases and against snake bites. In this study, the antioxidant activity of extracts and flavonoids (quercetin, catechin, epicatechin, rutin and astilbin) isolated from roots and leaf stalks of E. precatoria was investigated using β-carotene in TLC plates and DPPH radical scavenging in a spectrophotometric bioassay. All extracts and flavonoids showed activity. Also, the cytotoxic activity of these extracts was evaluated by the brine shrimp (Artemia salina) larvicide bioassay and was lower than that of lapachol, used as control. The presence of flavonoids and sitosterol-3-O-β-D-glucopyranoside in the extracts can justify the use of the plant in traditional medicine. (author)

    In this paper we suggest a design of a web marketplace where users of scientific application software and databases, presented in the form of web services, as well as their providers will have presence simultaneously. The model, which will be the basis for the web marketplace is close to the customer-to-customer (C2C) model, which has been successfully used, for example, on the auction sites such as eBay (ebay.com). Unlike the classical model of C2C the suggested marketplace focuses on application software in the form of web services, and standardization of API through which application software will be integrated into the web marketplace. A prototype of such a platform, entitled eSciMart, is currently being developed at SINP MSU.

    Size sexual dimorphism was investigated on 695 skulls of four Mustelidae species. By extent of increasing of differences between sexes the species are placed in following order: European pine marten (Martes martes), European mink (Mustela lutreola), American mink (Neovison vison), and European polecat (Mustela putorius). Extent of the dimorphism characterizes ecological plasticity of the species and is population characteristic. It is shown that M. martes takes specific and relatively narrow ecological niche of forest ecosystems, entering into weak competitive relationships with smaller Mustelidae species. The level of sexual dimorphism of M. lutreola, N. vison and M. putorius reflects intensity of its interspecific relationships within study area. High level of sexual dimorphism of M. putorius is determined by further divergence of ecological niches of males and females, and also appears to be compensatory mechanism reducing consequences of hardened environmental requirements.

  4. Improved immunohistochemical evaluation of micrometastases in sentinel lymph nodes of cutaneous melanoma with 'MCW Melanoma Cocktail' – A mixture of monoclonal antibodies to MART-1, melan-A, and tyrosinase

    MART-1, Melan-A, and Tyrosinase have shown encouraging results for evaluation of melanoma micrometastases in sentinel lymph nodes, as compared to conventionally used S-100 protein and HMB-45. To achieve higher sensitivity, some studies recommend evaluation of three sections, each at intervals of 200 μ. This would mean, routine staining of three adjacent sections in each of the three clusters at intervals of 200 μ, requiring nine slides resulting in added expense. If a cocktail of these antibodies could be used, only one section would be required instead of three generating significant cost savings. We prepared a combination of monoclonal antibodies to these three immunomarkers in optimized dilutions (MART-1, clone M2-7C10, dilution 1:500; Melan-A, clone A103, dilution 1:100; and Tyrosinase, clone T311, dilution 1:50) and designated it as 'MCW melanoma cocktail'. Formalin-fixed paraffin-embedded tissue sections of sentinel lymph nodes from patients with cutaneous melanoma, without macro-metastases were evaluated with this cocktail. Melanoma micrometastases were easily detectable with the cocktail in 41 out of 188 slices (8/24 cases). The diagnostic accuracy amongst five pathologists did not show statistically significant difference. Out of 188 slices, 78 had adjacent sections immunostained individually with MART-1 and Melan-A during our previous study. Of these 78 slices, 21 were positive for melanoma micrometastases with MART-1 and Melan-A individually. However, the adjacent section of these slices immunostained with the cocktail detected metastases in four additional slices. Thus, MART-1 and Melan-A could not detect melanoma micrometastases individually in 16% (4/25) of slices positive with the cocktail. Benign capsular nevi were immunoreactive for the cocktail in 4.8% (9/188) slices. All 81 slices of negative test controls (sentinel lymph nodes of mammary carcinoma) were interpreted correctly as negative for melanoma micrometastases. The melanoma

    Background: The characterization of the genes encoding melanoma-associated antigens MART-1 or gp100, recognized by T cells, has opened new possibilities for the development of immunization strategies for patients with metastatic melanoma. With the use of recombinant adenoviruses expressing either MART-1 or gp100 to immunize patients with metastatic melanoma, we evaluated the safety, immunologic, and potential therapeutic aspects of these immunizations. Methods: In phase I studies, 54 patients received escalating doses (between 107 and 1011 plaque-forming units) of recombinant adenovirus encoding either MART-1 or gp100 melanoma antigen administered either alone or followed by the administration of interleukin 2 (IL-2). The immunologic impact of these immunizations on the development of cellular and antibody reactivity was assayed. Results: Recombinant adenoviruses expressing MART-1 or gp100 were safely administered. One of 16 patients with metastatic melanoma receiving the recombinant adenovirus MART-1 alone experienced a complete response. Other patients achieved objective responses, but they had received IL-2 along with an adenovirus, and their responses could be attributed to the cytokine. Immunologic assays showed no consistent immunization to the MART-1 or gp100 transgenes expressed by the recombinant adenoviruses. High levels of neutralizing antibody were found in the pretreatment sera of the patients. Conclusions: High doses of recombinant adenoviruses could be safely administered to cancer patients. High levels of neutralizing antibody present in patients' sera prior to treatment may have impaired the ability of these viruses to immunize patients against melanoma antigens. PMID:9862627

    2014-01-01

    Full Text Available Combretum leprosum Mart. is a tree species native of the Caatinga, used in the restoration of degraded areas and in folk medicine. Thus, this research aimed to evaluate the germination and vigor of the seeds subjecting them to different pre-germinative treatments, temperatures and substrates. In the first experi- ment, we tested the pre-germinative treatments: mechanical scarification with sandpaper, chemical scarification with H2SO4 for 1, 5, 10 and 20 minutes, immersion in water at 80 oC and imbibition in distilled water for 24 hours, beyond of the control. In the second experiment, after treatment of imbibition in water for 24 hours, the experimental design was completely randomized in a factorial 5 x 4 (five substrates: into paper, sand, coconut fiber, vermiculite and paper towel organized in the form of rolls; and four temperatures: 25, 30, 35 and 20-30 oC. The following parameters were evalueted: seed moisture content, germination, germination speed index, first germination count and seedling length and dry matter weight. The seeds of Combretum leprosum have not coat dormancy. However, pre-germinative treatments of mechanical scarification with sandpaper and imbibi- tion in water for 24 hours allows better expression of seeds vigor. The paper towel and the temperatures of 25, 30 and 20-30 oC provide adequate conditions for evaluating the germination of Combretum leprosum seeds.

    This study evaluated, in vitro, the antimicrobial activity of the hexane extract (JCHE), methanol extract (JCME), and chloroform fraction (JCCF) of bark from Jacaranda cuspidifolia Mart. (Family Bignoniaceae), a Brazilian medicinal plant, traditionally used as anti-syphilis and anti-gonorrhea treatment. The antimicrobial activity was evaluated using the disc diffusion method followed by the determination of minimum inhibitory concentration (MIC) values. JCHE was not active against the bacteria evaluated. JCME presented antibacterial activity against Streptococcus pyogenes, Staphylococcus aureus, and Neisseria gonorrhoeae with MIC values of 16.3 mg/mL, 9.1 mg/mL, and 25.2 mg/mL, respectively. JCCF was active against Staphylococcus epidermidis, S. aureus, Proteus mirabilis, Serratia marcescens, S. pyogenes, Enterobacter aerogenes, and N. gonorrhoeae with MIC values of 18.3 mg/mL, 9.3 mg/mL, 6.3 mg/mL, 6.1 mg/mL, 9.2 mg/mL, 6.2 mg/mL, and 25.2 mg/mL, respectively. Phytochemical analysis of JCME and JCCF gave positive results for saponins, coumarins, flavonoids, tannins, quinones, alkaloids, triterpenes, and steroids. Verbascoside was isolated and identified as a major peak in JCME and JCCF high-performance liquid chromatography fingerprints and might contribute to the observed antimicrobial activity.

  18. Rural maternity care: can we learn from Wal-Mart?

    2010-03-01

    In many countries rural maternity care is under threat. Consequently rural pregnant women will have to travel further to attend larger maternity units to receive care and deliver their babies. This trend is not dissimilar from the disappearance of other rural services, such as village shops, banks, post offices and bus services. We use a comparative approach to draw an analogy with large-scale supermarkets, such as the Wal-Mart and Tesco and their effect on the viability of smaller rural shops, depersonalisation of service and the wider community. The closure of a community-maternity unit leads to women attending a different type of hospital with a different approach to maternity care. Thus small community-midwifery units are being replaced, not by a very similar unit that happens to be further away, but by a larger obstetric unit that operates on different models, philosophy and notions of risk. Comparative analysis allows a fresh perspective on the provision of rural maternity services. We argue that previous discussions focusing on medicalisation and change in maternity services can be enhanced by drawing on experience in other sectors and taking a wider societal lens.

    Full Text Available Clay deposit collected from various locations in Marte (Northern Borno, were studied to determine their physical and chemical characteristics in order to evaluate their suitability for industrial uses. Major and trace element analyses were carried out on clay samples using Inductively Couple Plasma-Optical Emission Spectrometry (ICP-OES and X- Ray Fluorescence (XRF. The result of the chemical analysis of the ten (10 samples collected showed significant amounts of SiO2 and Al2O3. Silica content ranges from 51.48 to 62.44 % while alumina varies from 12.49 to 19.00 %. The calcium oxide ranges from 1.17 to 3.39 %, Na2O ranges from 1.1 to 8.61 %, K2O from 1.54 to 3.66 %, MgO varies from 0.04 to0.14 %, Fe2O3 varies from 0.3 to 2.7 % and MnO ranges from 0.01 to 1.03 %. The result showed that the clays are mainly smectite with quartz and felspar as the main non-clay minerals. Generally, the geochemical results of the samples do not meet the standard for industrial utilization when compared to the Industrial specifications. However, for industrial utilization, some of the clay samples may be used after necessary beneficiations.

    Traditional knowledge (TK) has enabled communities to adapt to changes in life conditions over centuries. However, this local context is being dramatically affected by recent changes through globalization and modernization of societies. In this paper we seek to identify socio-economic factors that are related to the knowledge and use of two palm species in mestizo and indigenous communities in the Amazonian of Peru and Bolivia. Both species are known in the region under the main vernacular name of Asaí, and are source of two highly commercialized resources: palm-hearts and fruits. Euterpe precatoria Mart. is native to the region whereas E. oleracea Mart. is being introduced for the use of both resources. We compare TK about the two Euterpe species in both countries in relation to 14 socioeconomic factors in seven use categories. We performed a Multivariate analysis of variance (MANOVA) to elucidate the influence of each socioeconomic factor on the overall palm knowledge or on individual use categories. In the two countries, we found that mestizos, speaking only Spanish, and migrants in the same ecoregion, knew more uses in all use categories for E. precatoria than for E. oleracea, even in use categories such as Medicinal and veterinary and Construction, for which indigenous participants had more uses in case of other species. In Peru, the use of E. precatoria was higher among participants with greater wealth, which could be related to the commercial importance that both the fruits and the palm-hearts have had in the markets of the region. In contrast, in Bolivia, although some income generation from Euterpe sp. was observed, the use of E. precatoria was much more homogeneously distributed. The use of E. oleracea in Bolivia is recent, and although its most important uses are related to the consumption of fruits and palm-hearts (Human food), it is now being slowly used for Medicinal and Construction purposes, similar to E. precatoria.

    Full Text Available A. crassiflora Mart. a Brazilian savannah fruit, is a source of phytochemical compounds that possess a wide array of biological activities, including free radical scavenging. This native fruit proved to potentialize the mutagenic process in previous in vivo investigations. The aim of the present study was to investigate the effects of A. crassiflora Mart. pulp intake on colonic cell proliferation and on the development of Aberrant Crypt Foci (ACF in male Wistar rats. The animals were fed with either a commercial diet or a diet supplemented with A. crassiflora Mart. pulp mixed in 1%, 10% or 20% (w/w for 4 weeks or 20 weeks. The carcinogen 1,2-dimethylhydrazine dihydrochloride (4 doses, 40 mg kg-1 each was used to induce colonic ACF. After euthanasia, the blood, liver and colon samples were collected for biochemical determinations, oxidative stress or ACF development analysis, respectively. Immunohistochemical analyses of the colonic mucosa were performed using antibodies against proliferating cell nuclear antigen (PCNA in normal-appearing colonic crypt and β-catenin in ACF. There was no ACF development in the colon from groups treated with A. crassiflora Mart. pulp. Also, the biochemical and oxidative stress analysis, PCNA labeling and ACF development (number, multiplicity or cellular localization of β-catenin were unchanged as a result of marolo pulp intake. Thus, the present results suggest that A. crassiflora Mart. pulp intake did not exert any protective effect in the colon carcinogenesis induced by DMH in rats.

    1995-01-01

    Technical specifications have been developed on the bases of deterministic analyses, engineering judgment, and expert opinion. This paper introduces our risk-based approach to surveillance test interval (STI) optimization. This approach consists of three main levels. The first level is the component level, which serves as a rough estimation of the optimal STI and can be calculated analytically by a differentiating equation for mean unavailability. The second and third levels give more representative results. They take into account the results of probabilistic risk assessment (PRA) calculated by a personal computer (PC) based code and are based on system unavailability at the system level and on core damage frequency at the plant level

    Full Text Available Nearly 230 species of biting midges have been recorded or described from Argentina; 38 of them are known from the Buenos Aires province and only one is cited from Martín García Island. This paper presents the results raised from six collecting trips which took place on the island during spring 2005, summer 2006 and autumn 2009. Diverse sampling sites including permanent and temporary aquatic environments were chosen, most of the ten sampling sites were ponds of diverse origin, some of these environments were covered with floating vegetation as Lemna gibba, Lemna minuscule, Salvinia biloba, Salvinia minima, Azolla filiculoides, Limnobium laevigatum, Pistia stratiotes, Spirodela intermedia, Wolffiella oblonga and Wolffia columbiana. Other sites were placed in urban and suburban areas. Adults were collected with sweep nets at sunrise and sunset and with light traps at intervals of four to five hours at night, depending on electricity availability on the island. Larvae and pupae were collected with different implements depending on characteristics of each surveyed aquatic habitat. In free standing water, they were captured with small sieves or hand pipettes and micropipettes, flotation techniques were utilized for sampling vegetated areas, free and rooted floating hydrophytes were extracted for removing insects among them. Thirteen species of Ceratopogonidae were collected, three of Atrichopogon Kieffer, three of Forcipomyia Meigen, two of Dasyhelea Kieffer, four of Culicoides Latreille, and one of Bezzia Kieffer, all representing new records from the island.

  6. Chaos on the interval

    Ruette, Sylvie

    2017-01-01

    The aim of this book is to survey the relations between the various kinds of chaos and related notions for continuous interval maps from a topological point of view. The papers on this topic are numerous and widely scattered in the literature; some of them are little known, difficult to find, or originally published in Russian, Ukrainian, or Chinese. Dynamical systems given by the iteration of a continuous map on an interval have been broadly studied because they are simple but nevertheless exhibit complex behaviors. They also allow numerical simulations, which enabled the discovery of some chaotic phenomena. Moreover, the "most interesting" part of some higher-dimensional systems can be of lower dimension, which allows, in some cases, boiling it down to systems in dimension one. Some of the more recent developments such as distributional chaos, the relation between entropy and Li-Yorke chaos, sequence entropy, and maps with infinitely many branches are presented in book form for the first time.

    Full Text Available Este trabajo expone y examina los cambios de percepción que experimentó José Martí sobre el papel de los pueblos originarios de América, entre 1875 y 1878, años en los que vivió en México y Guatemala, con intensa escala en Yucatán, lugares donde conoció directamente la cultura y el pueblo maya. Martí resume una visión inicial de nuestra América en la figura lítica de Chacmool cuando después de ser expropiada por el gobierno yucateco, el Apóstol cubano la admira en la ciudad de Mérida y expresa que es la síntesis de las culturas americanas. Aspecto poco estudiado en la obra de Martí es este acercamiento etnográfico a la realidad maya de Yucatán y Guatemala.   This paper aims at presenting and examining the change of perception José Martí underwent in relation to the role of the native peoples of America between 1875 and 1878, the years he lived in Mexico and Guatemala, during which he spent a large amount of time in Yucatan, where he was able to get to know the Mayan culture and its people first hand. Martí summarized his initial vision of our America in the lithic figure of Chacmool, which he was able to admire in the city of Merida, after it had been expropriated by the government of Yucatan. The Cuban apostle described this as a synthesis of American cultures. This ethnographic insight into the Mayan reality in Yucatan and Guatemala represents a scarcely explored aspect of Martí's work.

    Translational research typically requires data abstracted from medical records as well as data collected specifically for research. Unfortunately, many data within electronic health records are represented as text that is not amenable to aggregation for analyses. We present a scalable open source SQL Server Integration Services package, called Regextractor, for including regular expression parsers into a classic extract, transform, and load workflow. We have used Regextractor to abstract discrete data from textual reports from a number of 'machine generated' sources. To validate this package, we created a pulmonary function test data mart and analyzed the quality of the data mart versus manual chart review. Eleven variables from pulmonary function tests performed closest to the initial clinical evaluation date were studied for 100 randomly selected subjects with scleroderma. One research assistant manually reviewed, abstracted, and entered relevant data into a database. Correlation with data obtained from the automated pulmonary function test data mart within the Northwestern Medical Enterprise Data Warehouse was determined. There was a near perfect (99.5%) agreement between results generated from the Regextractor package and those obtained via manual chart abstraction. The pulmonary function test data mart has been used subsequently to monitor disease progression of patients in the Northwestern Scleroderma Registry. In addition to the pulmonary function test example presented in this manuscript, the Regextractor package has been used to create cardiac catheterization and echocardiography data marts. The Regextractor package was released as open source software in October 2009 and has been downloaded 552 times as of 6/1/2012.

    Full Text Available For sustainable use of native plant species, knowledge of the amount of harvestable biomass is necessary. This study presents data on allometric relationships of Lychnophora ericoides Mart. (Asteraceae, an extractive resource in the Cerrado region of Brazil. On the Fazenda Água Limpa (15º 45'S, 47º 57'W of the Universidade de Brasilia, 38 individuals of this species were measured in the field, the parts above ground were harvested, separated into components and oven dried. The best regression equations to estimate biomass were geometric and the best fit was between total height and total biomass (r² = 0.923. The economically useful portions, the leaves and branches accounted for approximately 20% of total above ground dry weight, but when used as the dependent variable, the strength of the relationship decreased (r² = 0.694. The relationship between branch diameter and leaf biomass was similar to that between height and leaf dry weight (r² = 0.600. The relation between the number of leaves and their biomass was linear but weak. The development of these equations is the first step towards the implementation of plans for sustainable use of this species.Para o uso sustentável das espécies vegetais nativas o conhecimento da quantidade de biomassa disponível é necessário.

    The diagnosis of melanoma metastatic to lymph node remains a difficult problem given its histological diversity. We examined the staining patterns of S-100, NK1/C3, HMB-45, and MART-1 (DC10) in melanoma metastases to lymph nodes. Immunohistochemical stains were performed on tissue sections of 126 formalin-fixed lymph nodes from 126 patients with an established diagnosis of metastatic melanoma. A total of 98% of cases (123 of 126) stained positive for S-100, 93% (117 of 125) stained positive for NK1/C3, 82% (103 of 126) stained positive for MART-1, and 76% (95 of 125) stained positive for HMB-45. The distribution and intensity of staining varied among these markers. A diffuse staining pattern, defined as >50% of tumor cells stained, was observed in 83% of MART-1-positive cases but in only 56% of S-100-positive cases, 48% of NK1/C3-positive cases, and 34% of HMB-45-positive cases. A maximally intense signal was almost always observed for MART-1 (83% of positive cases) but was rarely observed for NK1/C3 (20%). S-100 and HMB-45 showed maximally intense staining in 50% and 54% of cases, respectively. S-100 and NK1/C3 stained both histiocytes and melanocytes, whereas MART-1 and HMB-45 stained only melanocytes. Seventy-eight cases (63%) stained positive for all 4 markers, 17 cases (14%) stained for all markers except HMB-45, 13 cases (10%) stained for all markers except MART-1, 6 cases (5%) stained only with S-100 and NK1/C3, 4 cases (3%) stained only with S-100 and HMB-45, and 2 cases stained for all markers except S-100. One case each stained for the following: only S-100, only S-100 and HMB-45, and all markers except NK1/C3. One case exhibited absence of staining for any of these markers. We demonstrate that lymph node metastases of melanoma are heterogeneous with regard to tumor marker expression. S-100 and NK1/C3 were the most sensitive stains for detecting metastatic melanoma; however, they both also stain other nontumor cells in lymph nodes. MART-1 did not stain

    This chapter contains selected papers presented at the Minisymposium on Interval Methods of the PARA'04 Workshop '' State-of-the-Art in Scientific Computing ''. The emphasis of the workshop was on high-performance computing (HPC). The ongoing development of ever more advanced computers provides...... the potential for solving increasingly difficult computational problems. However, given the complexity of modern computer architectures, the task of realizing this potential needs careful attention. A main concern of HPC is the development of software that optimizes the performance of a given computer....... An important characteristic of the computer performance in scientific computing is the accuracy of the Computation results. Often, we can estimate this accuracy by using traditional statistical techniques. However, in many practical situations, we do not know the probability distributions of different...

  17. Experimenting with musical intervals

    Science.gov (United States)

    Lo Presto, Michael C.

    2003-07-01

    When two tuning forks of different frequency are sounded simultaneously the result is a complex wave with a repetition frequency that is the fundamental of the harmonic series to which both frequencies belong. The ear perceives this 'musical interval' as a single musical pitch with a sound quality produced by the harmonic spectrum responsible for the waveform. This waveform can be captured and displayed with data collection hardware and software. The fundamental frequency can then be calculated and compared with what would be expected from the frequencies of the tuning forks. Also, graphing software can be used to determine equations for the waveforms and predict their shapes. This experiment could be used in an introductory physics or musical acoustics course as a practical lesson in superposition of waves, basic Fourier series and the relationship between some of the ear's subjective perceptions of sound and the physical properties of the waves that cause them.

    2007-10-01

    Full Text Available The present article examines constructions of  race, nation and mestizaje in work of Domingo  Faustino Sarmiento, José Martí and Eugenio  Maria de Hostos. The first championed the prevailing nineteenth-century view that humanity  was being debilitated by a constant battle between  civilization and barbarism while the two Antilleans questioned it in their search for a society  liberated from coloniality. Martí denied the notion  of privilege based on Europeanness, proclaiming  that whites, blacks, indigenous and mixed-race  peoples could all claim equal rights under natural  law. Hostos agreed with Martí but took his recommendation one step further by proposing race  mixing, with all ethnic groups equally forming a  new society. Therefore Martí’s negation of racial  differences becomes with Hostos a quest for a  society that would eventually become homogeneous through miscegenation. The study concludes  that there is a timelessness inherent to Martí and  Hostos’s work that still speaks to us today in the  midst of a new awareness of ethnicity’s impact on  society. Resumen:De Sarmiento a Martí y Hostos: Rescatando al país de la colonialidadEl presente artículo examina las construcciones de  raza, nación y mestizaje en las obras de Domingo  Faustino Sarmiento, José Martí y Eugenio María de  Hostos.

Martí niega la noción de privilegio basado en  lo europeo y proclama que los blancos, negros,  indígenas y personas de raza mezclada podrían  reclamar la igualdad de derechos bajo leyes naturales.

    Full Text Available

    Halfway through the 16th century in Spain the reading and interpretation of the Bible based on its original languages involved a very real danger for humanists who were seeking a better understanding of the Scriptures. The exclusive authority of the Latin Vulgate version declared by the Council of Trent in 1546 hindered the intellectual work of many Biblicists and Theologians, who were subjected to tight ideological control. In this context it must be considered the case of the Hebraist and scholar from the University of Salamanca, Martín Martínez de Cantalapiedra (1518-1579, who was prosecuted by the Inquisition of Valladolid in 1572 along with his colleagues Fray Luis de León and Gaspar de Grajal. All of them were accused of deviating from the genuine sense of the Vulgate in their more literal interpretations of the Masoretic text. The purpose of this article is to provide new evidence for the intellectual biography of Master Martínez de Cantalapiedra as well a to analyze the hermeneutical principles exposed during his inquisitorial in which he defended the Hebrew knowledge as an essential means of interpreting the Old Testament.

    EPICS is used worldwide mostly for controlling accelerators and large experimental physics facilities. Although EPICS is well fit for the design and development of automation systems, which are typically VME or PLC-based systems, and for soft real-time systems, it may present several drawbacks when used to develop hard real-time systems/applications especially when general purpose operating systems as plain Linux are chosen. This is in particular true in fusion research devices typically employing several hard real-time systems, such as the magnetic control systems, that may require strict determinism, and high performance in terms of jitter and latency. Serious deterioration of important plasma parameters may happen otherwise, possibly leading to an abrupt termination of the plasma discharge. The MARTe framework has been recently developed to fulfill the demanding requirements for such real-time systems that are alike to run on general purpose operating systems, possibly integrated with the low-latency real-time preemption patches. MARTe has been adopted to develop a number of real-time systems in different Tokamaks. In this paper, we first summarize differences and similarities between EPICS IOC and MARTe. Then we report on a set of performance measurements executed on an x86 64 bit multicore machine running Linux with an IO control algorithm implemented in an EPICS IOC and in MARTe.

  18. Numerical Simulations to Assess ART and MART Performance for Ionospheric Tomography of Chapman Profiles.

    Science.gov (United States)

    Prol, Fabricio S; Camargo, Paulo O; Muella, Marcio T A H

    2017-01-01

    The incomplete geometrical coverage of the Global Navigation Satellite System (GNSS) makes the ionospheric tomographic system an ill-conditioned problem for ionospheric imaging. In order to detect the principal limitations of the ill-conditioned tomographic solutions, numerical simulations of the ionosphere are under constant investigation. In this paper, we show an investigation of the accuracy of Algebraic Reconstruction Technique (ART) and Multiplicative ART (MART) for performing tomographic reconstruction of Chapman profiles using a simulated optimum scenario of GNSS signals tracked by ground-based receivers. Chapman functions were used to represent the ionospheric morphology and a set of analyses was conducted to assess ART and MART performance for estimating the Total Electron Content (TEC) and parameters that describes the Chapman function. The results showed that MART performed better in the reconstruction of the electron density peak and ART gave a better representation for estimating TEC and the shape of the ionosphere. Since we used an optimum scenario of the GNSS signals, the analyses indicate the intrinsic problems that may occur with ART and MART to recover valuable information for many applications of Telecommunication, Spatial Geodesy and Space Weather.

  3. Ionizing radiation affects generation of MART-1-specific cytotoxic T cell responses by dendritic cells

    International Nuclear Information System (INIS)

    2003-01-01

    Full text: The human MART-1/Melan-A (MART-1) melanoma tumor antigen is known to be recognized by cytotoxic T lymphocytes (CTLs) and several groups are using this target for clinical immunotherapy. Most approaches use dendritic cells (DCs) that are potent antigen presentation cells for initiating CTL responses. In order for CTL recognition to occur, DCs must display 9-residue antigenic peptides on MHC class I molecules. These peptides are generated by proteasome degradation and then transported through the endoplasmic reticulum to the cell surface where they stabilize MHC class I expression. Our previous data showed that irradiation inhibits proteasome function and, therefore, we hypothesized that irradiation may inhibit antigen processing and CTL activation, as has been shown for proteasome inhibitors. To study the importance of irradiation effects on DCs, we studied the generation MART-1-specific CTL responses. Preliminary data showed that irradiation of murine bone marrow derived DCs did not affect expression of MHC class I, II, CD80, or CD86, as assessed by flow cytometric analyses 24-hour after irradiation. The effect of irradiation on MART-1 antigen processing by DCs was evaluated using DC transduced with adenovirus MART-1 (AdVMART1). C57BL/6 mice were immunized with AdVMART1 transduced DCs, with and without prior irradiation. IFN-γ production was measured by ELISPOT assays after 10-14 days of immunization. Prior radiation treatment resulted in a significant decrease in MART-1-specific T cell responses. The ability of irradiated and non-irradiated AdVMART1/DC vaccines to protect mice against growth of murine B16 tumors, which endogenously express murine MART-1, was also examined. AdVMART1/DC vaccination protected C57BL/6 mice against challenge with viable B16 melanoma cells while DCs irradiated (10 Gy) prior to AdVMART1 transduction abrogated protection. These results suggest that proteasome inhibition in DCs by irradiation may be a possible pathway in

  4. Etnocentrismo, racismo y miedo: los indígenas y los incultos en Martí

    Directory of Open Access Journals (Sweden)

    Jorge Camacho

    2010-04-01

    Full Text Available In the following article I return to the idea of ethnicity and liberalism in Latin America during the last part of the 19th century. I also discuss Martí’s view of the Indians after 1885, when his chronicles were fueled by the rhetoric of pro-indigenous groups such as the Friends of Indians Association. I propose to look at other ways in which Martí’s ethnocentric view of culture and race intertwined with his agenda of “defending” the Indians, especially in his essay “Nuestra América.” For that purpose I retrace some of my previous arguments and discuss other essays that have recently elaborated on Martí’s “other side”, the one that imposes on the Indians his own liberal agenda, and the vision of modernity that the elites were constructing in Latin America at the end of 19th century. In my previous articles I discussed Martí’s chronicles on the Guatemalan, Mexican and American Indians and here I will focus on the similarities between the positivists in Mexico and Martí’s emphasis on “scientific politics” as well as his fear that those that were at the lowest level of society could one day revolt against the republic and destroy the justice “accumulated in books.” For books symbolized for Martí the “lettered elite”, those that had power and exercised it to their own advantage. He talked about this fear in Mexico, and in his most famous essay he returned to it again with a somewhat different perspective, but still with the conviction that within a democracy everything could be solved and a revolt from the “unlettered” masses was not justified. I argue that even if “Nuestra América” meant a more positive view of the “Indian problem”, Martí still considers the Indians, the “gauchos” and the rest of the “incultos” as a threat. They were the natural ally of the “caudillos” that ruled for so long Latin America, charismatic caudillos such as Juan Manuel de Rosas.

Nesse sentido, o presente estudo objetivou a avaliação da qualidade físico-química e funcional de polpas de açaí e bacaba processadas artesanalmente. Os frutos foram coletados em propriedades rurais do município do Cantá/Roraima (bacaba e Boa Vista/ Roraima (açaí. Para a constituição do experimento, as polpas processadas foram armazenadas em pequenas embalagens de politereftalato de etileno (PET transparente e com tampa (mesmo material, com capacidade de 145 mL e refrigeradas a 3 ± 0,2°C e 45% de U.R., durante 5 dias. Foram analisados os seguintes parâmetros: pH, acidez titulável (AT, sólidos solúveis (SS, relação SS/AT, açúcares totais e redutores, pectinas totais e solúveis, teor de antocianinas e fenólicos totais. Ao final, para as polpas de açaí, levando-se em consideração os limites estabelecidos pelo Padrão de Identidade e Qualidade (PIQ, apenas o parâmetro AT apresentou-se fora da instrução normativa. Entretanto, a inexistência de padrões para bacaba inviabilizou tal comparação. Quanto ao teor das pectinas totais, pode-se concluir que ambas as polpas apresentam baixas concentrações desse componente, não sendo indicadas para produção de doces e geleias sem adição de agentes geleificantes. Os teores de compostos fenólicos e de antocianinas, em ambas as polpas, apesar de diminuir com o período de armazenamento refrigerado, apresentam altas concentrações quando em comparação a outros alimentos com apelo funcional.

    Keeping in mind the proposed FAST experiment and aiming to meet basic requirements such as a modular and distributed architecture, where different control subsystems can be easily integrated at different times, and can operate either independently or in cooperation with other subsystems, at the end of last year we planned to upgrade the architecture of the FTU real-time system, improving in such a way its flexibility and modularity. We decided to adopt an available packages to reach our goal: MARTe. We report on the state of the art of the MARTe migration process, the difficulties dealt with, the benefits and advantages achieved, the progress made from our last report and, in particular, we describe the integration of the ODIN equilibrium reconstruction system in the real-time environment. The ODIN algorithm was already coded in previous works, but its integration in the real-time system has never been carried out at FTU. We illustrate how the MARTe architecture and the RTNet level allows for a first level of parallelization, distributing the data and/or time among nodes.

    Keeping in mind the proposed FAST experiment and aiming to meet basic requirements such as a modular and distributed architecture, where different control subsystems can be easily integrated at different times, and can operate either independently or in cooperation with other subsystems, at the end of last year we planned to upgrade the architecture of the FTU real-time system, improving in such a way its flexibility and modularity. We decided to adopt an available packages to reach our goal: MARTe. We report on the state of the art of the MARTe migration process, the difficulties dealt with, the benefits and advantages achieved, the progress made from our last report and, in particular, we describe the integration of the ODIN equilibrium reconstruction system in the real-time environment. The ODIN algorithm was already coded in previous works, but its integration in the real-time system has never been carried out at FTU. We illustrate how the MARTe architecture and the RTNet level allows for a first level of parallelization, distributing the data and/or time among nodes.

    Highlights: • The integration of two frameworks for real-time control and data acquisition is described. • The integration may significantly fasten the development of system components. • The system includes also a code generator for the integration of code written in Simulink. • A real-time control systemcan be implemented without the need of writing any line of code. - Abstract: Simulink is a graphical data flow programming tool for modeling and simulating dynamic systems. A component of Simulink, called Simulink Coder, generates C code from Simulink diagrams. MARTe is a framework for the implementation of real-time systems, currently in use in several fusion experiments. MDSplus is a framework widely used in the fusion community for the management of data. The three systems provide a solution to different facets of the same process, that is, real-time plasma control development. Simulink diagrams will describe the algorithms used in control, which will be implemented as MARTe GAMs and which will use parameters read from and produce results written to MDSplus pulse files. The three systems have been integrated in order to provide a tool suitable to speed up the development of real-time control applications. In particular, it will be shown how from a Simulink diagram describing a given algorithm to be used in a control system, it is possible to generate in an automated way the corresponding MARTe and MDSplus components that can be assembled to implement the target system.

    Highlights: • The paper describes the integration of two different frameworks for control and data acquisition. • It describes the way the two frameworks have been integrated. • It describes the advantages of this combined approach. • It presents a case study of the utilization of the two integrated frameworks. - Abstract: The recent long lasting fusion experiments introduced a change in paradigm for control and data acquisition. While formerly implemented by different systems, using different software and hardware solutions, new requirements, such as the need of handling a sustained data stream, the availability of powerful general-purpose computers and the evolution of Linux towards real-time responsiveness make an integrated solution nowadays feasible. In the fusion community several frameworks have been developed for control and data acquisition and some of them are shared among different experiments. In particular, MDSplus represents the most used framework for data acquisition and management and MARTe is a framework for real-time applications originally developed at JET, but then adopted in several other experiments. Neither system can be used alone to provide integrated real-time control and data acquisition but, since their functionality complements, they can be used in conjunction. To achieve this, an additional layer has been developed so that data handled in real-time by MARTe components can be redirected to pulse file for storage. At the same time, configuration data, typically defined in the MDSplus experiment model, can be seamlessly transferred to MARTe GAMs during system configuration.

    The Multi-threaded Application Real-Time executor (MARTe) is a C++ framework that provides a development environment for the design and deployment of real-time applications, e.g. control systems. The kernel of MARTe comprises a set of data-driven independent blocks, connected using a shared bus. This modular design enforces a clear boundary between algorithms, hardware interaction and system configuration. The architecture, being multi-platform, facilitates the test and commissioning of new systems, enabling the execution of plant models in offline environments and with the hardware-in-the-loop, whilst also providing a set of non-intrusive introspection and logging facilities. Furthermore, applications can be developed in non real-time environments and deployed in a real-time operating system, using exactly the same code and configuration data. The framework is already being used in several fusion experiments, with control cycles ranging from 50 microseconds to 10 milliseconds exhibiting jitters of less than 2%, using VxWorks R , RTAI or Linux. Codes can also be developed and executed in Microsoft Windows R and Solaris R . This paper discusses the main design concepts of MARTe, in particular the architectural choices which enabled the combination of real-time accuracy, performance and robustness with complex and modular data driven applications.

    Stability of dynamical systems against strong perturbations is an important problem of nonlinear dynamics relevant to many applications in various areas. Here, we develop a novel concept of interval stability, referring to the behavior of the perturbed system during a finite time interval. Based on this concept, we suggest new measures of stability, namely interval basin stability (IBS) and interval stability threshold (IST). IBS characterizes the likelihood that the perturbed system returns to the stable regime (attractor) in a given time. IST provides the minimal magnitude of the perturbation capable to disrupt the stable regime for a given interval of time. The suggested measures provide important information about the system susceptibility to external perturbations which may be useful for practical applications. Moreover, from a theoretical viewpoint the interval stability measures are shown to bridge the gap between linear and asymptotic stability. We also suggest numerical algorithms for quantification of the interval stability characteristics and demonstrate their potential for several dynamical systems of various nature, such as power grids and neural networks.

    Full Text Available Semblanza del escritor y político cubano José Martí (1853-1895, con especial atención a la vigencia de su pensamiento ético, base de su permanente actualidad. Martí fue el organizador y líder de la última guerra americana contra el colonialismo europeo clásico, pero el sentido profundo que dio a esa lucha la convirtió en una verdadera guerra de liberación nacional: el primer movimiento concreto contra el imperialismo. Entre los rasgos más originales del pensamiento martiano están: la proclamación de la igualdad de razas; la búsqueda de la superación de las diferencias de clase mediante el equilibrio de las fuerzas sociales; la reivindicación de la solidaridad hacia los humildes como un deber; la predicación de una “guerra sin odios”, que debía ser obra del pueblo y no de líderes; la comprensión y definición de Nuestra América; la insistencia en la necesidad de una descolonización cultural latinoamericana; y el antiimperialismo.   This paper is a sketch of the Cuban writer and politician José Martí (1853-1895, with special attention to the validity of his ethical thinking, which is the basis of his permanent relevance. Martí was the organizer and leader of the last American war against European colonialism, but the deep commitment he made to that struggle turned it into a war of national liberation, the first concrete movement against imperialism. Among the most original features of Martí’s thought are the proclamation of the equality of races; the search for overcoming class differences through the balance of social forces; solidarity with the poor being considered a duty; the preaching of a “war without hates” that must be the work of the people, its leaders; the comprehension and definition of Our America; the insistence on the need, throughout Latin America, of cultural decolonization; and an anti-imperialistic stance.

    This study aims to understand how the stem bark of Stryphnodendron rotundifolium Mart. is used by a rural community in the savanna of Northeastern Brazil, associated with a preliminary assessment involving plant population structure and extractivism in the main sites of collection. A population structure study and analysis of bark extractivism was conducted in two sites: one within the forest and another at its edge. We had the intention of testing whether there are differences between these sites; since the local extractive practice is prohibited, expecting more intense extraction in the forest interior than its edge by the local fiscalization. We interviewed 120 informants who reported knowing and using the species, and also the places of extractivism. We also calculated quantitative measures of local knowledge, and the influence of gender and age on the knowledge about this species. Knowledge of the uses was evenly distributed between men and women. A total of 28 specimens were recorded at Site 1, whereas 23 were identified at Site 2, with the specimens at both sites distributed in 4-diameter classes with 4-cm intervals. Nine of the specimens found in Site 1 (32.14%) showed some sign of extraction. No specimen from Site 2 showed signs of extraction. In Site 1, the total area of stem bark removed was 43,468 cm2, and the total area of stem bark available was 33,200 cm2. In Site 2, only the available stem-bark area of 44,666 cm2 was identified because no specimens were harvested. There is no difference in knowledge of this species regarding the gender and age. Stryphnodendron rotundifolium is a key resource for the studied community. A large proportion of bark collected from the first diameter size class may affect the growth of these individuals and may influence the recruitment process. Perhaps, this effect may explain the absence of individuals in some size classes.

  15. Generalized Confidence Intervals and Fiducial Intervals for Some Epidemiological Measures

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available For binary outcome data from epidemiological studies, this article investigates the interval estimation of several measures of interest in the absence or presence of categorical covariates. When covariates are present, the logistic regression model as well as the log-binomial model are investigated. The measures considered include the common odds ratio (OR from several studies, the number needed to treat (NNT, and the prevalence ratio. For each parameter, confidence intervals are constructed using the concepts of generalized pivotal quantities and fiducial quantities. Numerical results show that the confidence intervals so obtained exhibit satisfactory performance in terms of maintaining the coverage probabilities even when the sample sizes are not large. An appealing feature of the proposed solutions is that they are not based on maximization of the likelihood, and hence are free from convergence issues associated with the numerical calculation of the maximum likelihood estimators, especially in the context of the log-binomial model. The results are illustrated with a number of examples. The overall conclusion is that the proposed methodologies based on generalized pivotal quantities and fiducial quantities provide an accurate and unified approach for the interval estimation of the various epidemiological measures in the context of binary outcome data with or without covariates.

The aim of this study was to evaluate the antioxidant capacity of extracts and isolated compounds from this plant. The antioxidant activity of the crude and semipurified extracts and isolated compounds was evaluated through DPPH-radical and phosphomolybdenum-complex assays. By both methods, the ethyl-acetate fraction demonstrated better antioxidant capacity compared with vitamin C and trolox. In the compounds, the higher the number of hydroxyls, the greater the antioxidant activity. In addition, stereochemistry influenced antioxidant activity, i.e., compounds with 2 R,3 R showed greater activity than those with 2 R,3 S. (author)

    Full Text Available The fruits of asaí (Euterpe precatoria Mart. are a traditional food for Amazonian inhabitants who harvest it from wild populations, employing management practices that affect palm populations and productivity. Here we present management data on fruit harvesting in a Tikuna community in the Colombian Amazon. We identified the market structure in Leticia and evaluated the population structure and fruit productivity in a scarcely harvested forest and a heavily harvested one. We performed interviews to determine management and market practices and we established plots to identify population structure and productivity. Harvesting is mostly for self-supply and palm felling is the main method. The fruits are mostly consumed and marketed as juice. The asaí market is small and seasonal but it represents an important source of income for many, mainly indigenous, families. The population density was 1 680 individuals and 248 adults/ha in San Martín de Amacayacu, where harvesting was from 2 % of all adult palms, and 916 individuals and 30 adults/ha in Leticia, where harvesting was from 23 % of all adult palms. The population structure in both sites followed an in-verted J-curve in which the majority of the individuals were seedlings. Productivity was 2.2 ton/ha/ year in San Martín de Amacayacu and 0.33 ton/ha/ year in Leticia. The population in Leticia is heavily harvested to supply the local market and the consequences of this use are a reduction in population density and fruit productivity and a low abundance of individuals in all size classes.

    Full Text Available The configuration information of Integrated Modular Avionics (IMA system includes almost all details of whole system architecture, which is used to configure the hardware interfaces, operating system, and interactions among applications to make an IMA system work correctly and reliably. It is very important to ensure the correctness and integrity of the configuration in the IMA system design phase. In this paper, we focus on modelling and verification of configuration information of IMA/ARINC653 system based on MARTE (Modelling and Analysis for Real-time and Embedded Systems. Firstly, we define semantic mapping from key concepts of configuration (such as modules, partitions, memory, process, and communications to components of MARTE element and propose a method for model transformation between XML-formatted configuration information and MARTE models. Then we present a formal verification framework for ARINC653 system configuration based on theorem proof techniques, including construction of corresponding REAL theorems according to the semantics of those key components of configuration information and formal verification of theorems for the properties of IMA, such as time constraints, spatial isolation, and health monitoring. After that, a special issue of schedulability analysis of ARINC653 system is studied. We design a hierarchical scheduling strategy with consideration of characters of the ARINC653 system, and a scheduling analyzer MAST-2 is used to implement hierarchical schedule analysis. Lastly, we design a prototype tool, called Configuration Checker for ARINC653 (CC653, and two case studies show that the methods proposed in this paper are feasible and efficient.

  5. Inconsciente genérico, feminismo y Nubosidad variable de Carmen Martín Gaite

    Zecchi, Barbara

    2006-08-01

    Full Text Available In a context of marked tensions between gynocritics and contemporary Spanish women writers, Carmen Martín Gaite’s novel Nubosidad variable (Variable Cloud,1992 stands out as a curious paradox. As is well known, Martín Gaite repeatedly declared not to be a feminist and even scorned women who fought for equality between both sexes. This article argues that Nubosidad variable, however, constitutes one of the best examples of a consciously feminist text. In this novel Martín Gaite applies some of the most prominent paradigms of feminist literary theory, such as the construction of a non-linear and a-chronological narration (Julia Kristeva, the attempt to create a “language of the body” (Helène Cixous, the foregrounding of a mother-daughter bond (Luisa Muraro, as well as the use of female writing as a means of self-discovery (Elaine Showalter.En un contexto de falta de comunicación entre ginocrítica y escritura femenina, la novela Nubosidad variable (1992 de Carmen Martín Gaite se presenta como una significativa paradoja. Si por un lado su autora declaró repetidas veces no ser feminista —y hasta menospreció con ironía a las mujeres que han luchado por la igualdad—, Nubosidad variable es una innegable aplicación de algunos de los más conocidos paradigmas de la teoría literaria feminista. Desde la narración no-lineal y atemporal que sigue el “tiempo de las mujeres” de Julia Kristeva, hasta el intento de crear una lengua del cuerpo a lo Hélène Cixous; desde el vínculo madre-hija teorizado por Luisa Muraro, hasta la escritura femenina como auto-descubrimiento de Elaine Showalter, esta novela representa uno de los mejores ejemplos, dentro de la narrativa contemporánea española, de lo que llamaría un texto conscientemente feminista.

  15. An analysis of natural ventilation techniques to achieve indoor comfort in Wal-Mart express

    Science.gov (United States)

    O'Dea, Shona

    Despite global efforts to reduce world fossil fuel dependency the world still obtains 81% of its energy from fossil fuels (IEA,2009). Modern renewable alternatives have been around since the mid twentieth century these alternatives have not been integrated into electrical grid systems at the exponential rate required to eradicate fossil fuels dependency. The problem, world energy demand, is too large to be satisfied by anything other than the energy-dense fossil fuels used today. We must change our energy intensive processes in order to conserve energy and hence reduce the demands that alternatives must satisfy. This research aims to identify sustainable design opportunities through the application of innovative technologies for the largest retailer in the US with the view that a viable conservative design measure could be applied to the store model, which is replicated across the country, causing a cumulative and hence larger impact on the company energy consumption as a whole. This paper will present the literature available on the 'big box' industry and Wal-Mart, comfort, natural ventilation and building simulation software and then perform an analysis into the viability of naturally ventilating the Wal-Mart Express sales zone using Monodraught natural ventilation windcatcher products

    Full Text Available Creada en 1962 por Sam Walton, una pequeña empresa de distribución norteamericana se convertirá rápidamente en la primera empresa mundial. Desde Bentonville, Arkansas, hasta el interior de China, Wal-Mart muestra un camino bastante clásico que va desde la sede principal de la empresa hacia una proliferación de sus tiendas en una quincena de países. Con una facturación de 405 mil millones de dólares en 2008, la empresa de distribución número uno en el mundo fue sobrepasada en abril de 2009 por la empresa petrolera Exxon Mobil en la clasificación de las quinientas empresas mundiales más importantes. Pero a diferencia de otras grandes transnacionales como Exxon Mobil o Microsoft, Wal-Mart, la primera empresa mundial de distribución, tiene que adaptarse al medio ambiente local con el fin de atraer a un máximo de consumidores. El artículo propone una aproximación a escala múltiple de las estrategias de desarrollo de esta firma internacional. Así, la aplicación de un análisis espacial es apropiada para esclarecer los vínculos existentes entre los territorios y las estrategias de los actores a diferentes escalas geográficas.

    Full Text Available In this study, we aimed to determine lignified tissue in young stems of Struthanthus vulgaris Mart. by infrared microspectroscopy and histochemical methods as well as by fluorescence microscopy. Struthanthus vulgaris Mart. is a mistletoe species that belongs to the Loranthaceae family. A brief anatomical description was also carried out. The first procedure for analysis was to elaborate anatomical cross sections (20-30 µm from young stems before and after treatment with NaOH 1%. This procedure was applied to release possible low molecular mass phenolic compounds. Safranin-astra blue was used to distinguish anatomical tissues while Wiesner test enabled verification of lignified pericyclic fibers. Infrared microspectroscopy analysis confirmed the presence of lignin in this region according to the following spectral signals: 1600 (shoulder, 1511, 1453, 1338 and 1244 cm-1. Analyses of the cross section of young stems under fluorescence microscopy before and after treatment with NaOH 1% allowed us to confirm the presence of low mass phenolic compounds in the region of pericyclic fibers.

    Full Text Available Beyond historical and social implications, migration represents the possibility of crossing a threshold and opening oneself up to new empirical and emotional spaces. Amparo, the main character of Carmen Martín Gaite’s Irse de casa (1998, is the perfect personification of the gaitian feminine canon. After leaving Spain and settling in New York, she became a successful fashion designer, and seemed happy and easy-going. The bond with memory and the past is the main topic of this novel, as it is in most of Martín Gaite’s production. The window on the past that Amparo closed moving to the US suddenly reappears when she needs to discover herself and her origins. This inconvenience in an anonymous life brings huge changes that will condition her and her loved ones. Travelling to Spain and interacting with places and people connected with her childhood, Amparo goes through the window she had closed forty years before, restoring the order. The window connects the present and the past, symbolizes the emigrant’s transience, personified in the novel by Amparo, who can definitely find the lost serenity and heart’s-ease.

  19. Historical biogeography sets the foundation for contemporary conservation of martens (genus Martes) in northwestern North America

    Effective conservation of insular populations requires careful consideration of biogeography, including colonization histories and patterns of endemism. Across the Pacific Northwest of North America, Pacific martens (Martes caurina) and American pine martens (Martes americana) are parapatric sister species with distinctive postglacial histories. Using mitochondrial DNA and 12 nuclear microsatellite loci, we examine processes of island colonization and anthropogenic introductions across 25 populations of martens. Along the North Pacific Coast (NPC), M. caurina is now found on only 2 islands, whereas M. americana occurs on mainland Alaska and British Columbia and multiple associated islands. Island populations of M. caurina have a longer history of isolation reflected in divergent haplotypes, private microsatellite alleles, and relatively low within-population diversity. In contrast, insular M. americanahave lower among-population divergence and higher metrics of within-population diversity. On some NPC islands, introductions of M. americana may be related to decline of M. caurina. Long-term persistence of these species likely has been influenced by anthropogenic manipulations, including wildlife translocations and industrial-scale deforestation, yet, the distinctive histories of these martens have not been incorporated into natural resource policies.

  2. Literatura y filosofía: Sartre, Martín-Santos y Bartleby

    Full Text Available Luis Martín Santos has been, after his soon death, one of the most unfairly forgotten Spanish intellectuals. This situation happens to be even more unjust considering the success of his novel “Time of Silence” and his unfinished “Time of Destruction”. The works of this psychiatrist, philosophically formed in the existentialism tradition, tackle from psychiatric and medical studies to interpretations of Dilthey, Jaspers and Heidegger. Maybe the most important achievement made by Dr. Martín-Santos was the fact of pooling in his novels all the different fields he worked in, namely: existential philosophy, psychiatry and literature. This mutual influence leads to a clearly existential interpretation of the narrative subject and to a nihilist conception of freedom: the nothingness completely understood as Sartre did. And, consequently, the attractiveness of approaching the Spanish author through literary theories that are close to the French contemporary philosophy and the primacy, not only of the existential analysis in literature, but also of the influence of the literary character as a fiction that is able to create possible realities. That is why it is interesting to study “Bartleby the Scrivener” as a paradoxical example of the existential nothingness made flesh. To put it in a nutshell, the existential triviality, a sign of modern times, has been indeed very successfully portrayed by Martín-Santos.Luis Martín-Santos ha sido, tras su temprana muerte, uno de los grandes olvidados entre los intelectuales españoles del franquismo. Olvido especialmente injusto, teniendo en cuenta el éxito de su novela Tiempo de Silencio y su interesante proyecto inacabado Tiempo de Destrucción. La obra de este psiquiatra formado filosóficamente en el existencialismo abarca desde trabajos psiquiátricos relativos a la medicina hasta interpretaciones de Dilthey, Jaspers y Heidegger. Tal vez el mayor logro de Martín- Santos fuera el de aunar en sus

    2001-01-01

    Inclusive diet production at large pseudorapidity intervals ( Delta eta ) between the two jets has been suggested as a regime for observing BFKL dynamics. We have measured the dijet cross section for large Delta eta in pp collisions at square root s = 1800 and 630 GeV using the DOE detector. The partonic cross section increases strongly with the size of Delta eta . The observed growth is even stronger than expected on the basis of BFKL resummation in the leading logarithmic approximation. The growth of the partonic cross section can be accommodated with an effective BFKL intercept of alpha /sub BFKL/(20 GeV) = 1.65 +or- 0.07.

La tesis es que el ideario de Martí expresó los intereses y la perspectiva de los pueblos de Hispanoamérica, a la que llamó Nuestra América, por oposición, según escribió “a la otra América, que no es nuestra”. Plenamente consciente de que la identidad de la región se sustentaba en una cultura nueva, mestiza de lo aborigen y lo español, el cubano dedicó su ensayo “Nuestra América” a explicar los factores internos que mantenían las estructuras sociales, políticas y de pensamiento de la época colonial, así como el peligro que representaba el creciente poderío de Estados Unidos.   This article aims to approach Cuban writer, thinker and politician José Martí's harsh, singular dialogue with modern thinking and its procedures. It argues that Martí's set of ideas expressed the interests and viewpoint of the peoples of Hispanic America, which he called Our America, as opposed to, according to his own texts, "the other America, the one that is not ours". Fully conscious of the fact that the region's identity was based on a new culture, resulting from a mix of the indigenous and the Spanish, Martí used his essay "Our America" (originally, "Nuestra América" to explain the internal factors that maintained the colonial social, political and ideological structures, in addition to expressing the threat the growing power of the United States represented.

    Full Text Available The article entitled Francisco Ibarra Martínez: reformer of Cuban Pedagogy, is first of all a well deserved homage to one of the most important pedagogues of the republican period. His thought and his work are approached, from his initial stage of academic formation to his contributions to the educational cuban thought. Stands out his social dimension of his pedagogic work, his integration to the civic life of the city, his reforming vision of the practice of sports and study of the history of his country. Likewise, we refer to his contributions to the historiography as a science, the journalism and his concern for the social and political destination of the country. For this reason this work has among its contributions the treatment to the local history from the specific fild of pedagogy and education, modestly contributing to the rescue of historic memory.

    The essential oils from leaves (sample A) and flowers (sample B) of Aeolanthus suaveolens Mart. ex Spreng were obtained by hydro distillation and analyzed by GC, GC-MS, and chiral phase gas chromatography (CPGC). Six compounds have been identified from the essential oils, representing ca 94.3 and 93% of the oils corresponding to samples A and B, respectively. The major constituents of samples A and B essential oils were respectively, linalool (34.2%/34.9%), (-)-massoialactone (25.9%/17.0%) and (E)-beta-farnesene (25.4%/29.1%). The enantiomeric distribution of the monoterpene linalool was established by analysis on heptakis-(6-O-methyl-2,3-di-O-pentyl)-beta-cyclodextrin capillary column. The antimicrobial activity of the essential oil from leaves and isolated compounds was also evaluated. (author)

    The use of natural fiber reinforcement thermoplastic polymer is continuously increasing. This fact is manly due to its advantages as low cost, availability, recyclability, low energy demand and then environmental appeal if compared to synthetics fibers. The composites were prepared in different fiber volume ratios (5%, 10% and 20%) mixed with high density polyethylene (HDPE) and heated at 190 deg C. Thermogravimetric analysis and differential scanning calorimetry were used to investigate thermal stability. The composites structure was characterized by Fourier Transform Infrared spectroscopy, X-ray diffractometry. Fiber and residue of piassava (Attalea funifera Mart) chemical composition were determined by Van Soest Method. The results indicate that thermo stability of the composites of HDPE prepared with fiber volume ratios up to 20% is only slightly lowered. (author)

    Decoction of roots of the Amazonian palm acai (Euterpe precatoria Mart.) is widely used by Brazilian and Peruvian people as an anti-inflammatory, to heal kidney and liver diseases and against snake bites. In this study, the antioxidant activity of extracts and flavonoids (quercetin, catechin, epicatechin, rutin and astilbin) isolated from roots and leaf stalks of E. precatoria was investigated using {beta}-carotene in TLC plates and DPPH radical scavenging in a spectrophotometric bioassay. All extracts and flavonoids showed activity. Also, the cytotoxic activity of these extracts was evaluated by the brine shrimp (Artemia salina) larvicide bioassay and was lower than that of lapachol, used as control. The presence of flavonoids and sitosterol-3-O-{beta}-D-glucopyranoside in the extracts can justify the use of the plant in traditional medicine. (author)

    Maytenus ilicifolia Mart. ex Reiss. Maytenus ilicifolia (Celastraceae) is a native plant of South America and popularly known as 'espinheira-santa'. The aim of this study was to evaluate the antioxidant capacity of extracts and isolated compounds from this plant. The antioxidant activity of the crude and semipurified extracts and isolated compounds was evaluated through DPPH-radical and phosphomolybdenum-complex assays. By both methods, the ethyl-acetate fraction demonstrated better antioxidant capacity compared with vitamin C and trolox. In the compounds, the higher the number of hydroxyls, the greater the antioxidant activity. In addition, stereochemistry influenced antioxidant activity, i.e., compounds with 2 R,3 R showed greater activity than those with 2 R,3 S. (author)

Previously, 19-Nor-2α-(3-hydroxypropyl-1α,25(OH2D3 (MART-10, the new brand 1α,25(OH2D3 analog, has been demonstrated to be an effective drug to inhibit HNSCC growth in vitro. Since most cancer patients die of metastasis, in this study, the antimetastatic effect of MART-10 on HNSCC was investigated. Our results reveal that both 1α,25(OH2D3 and MART-10 effectively repressed the migration and invasion of HNSCC cells, with MART-10 being much more potent than 1α,25(OH2D3. The antimetastatic effect of 1α,25(OH2D3 and MART-10 was mediated by attenuation of epithelial–mesenchymal transition (EMT, which was supported by the finding that the expression of EMT-inducing transcriptional factors, Sail and Twist, was inhibited by 1α,25(OH2D3 and MART

A área de estudo escolhida foi Thaumasia. O método aplicado baseia-se na teoria da Morfologia Matemática, sendo os rastros obtidos de maneira automática via processamento digital de imagens e binarização automática pelo método de otsu restrito. Os rastros foram detectados automaticamente nas imagens orbitais, o que permitiu calcular características importantes dos vórtices como: largura média e máxima, área de recobrimento, direção preponderante entre outros. Os resultados podem ser usados para auxiliar na compreensão do fenômeno que ocorre no ambiente marciano, contribuindo para o entendimento de como os vórtices de dust devils podem influenciar nas variações locais climáticas do planeta e se faz importante por ser o processo geológico em maior atividade no planeta.

    Full Text Available Mites associated to Xylopia aromatica (Lam. Mart. (Annonaceae in urban and rural fragments of semidecidual forest. Native plants can shelter a great diversity of mites. Notwithstanding, the conservation of the forest fragments where the plants are located can influence the structure of the mites community. Generally, in homogenous environments the diversity is lower due to the dominance of one or a few species. In this work, we studied the mite community on Xylopia aromatica (Lam. Mart. (Annonaceae in two fragments of semidecidual forest: one on rural and other on urban area. Seven individuals of X. aromatica were monthly sampled from April 2007 to March 2008, in each of these fragments. Descriptive indexes of diversity, dominance and evenness were applied to verify the ecological patterns of the mite community, besides the Student's t-test to compare the abundance between the fragments. We collected 27,365 mites of 37 species belonging to 11 families. Calacarus sp. (Eriophyidae was the most abundant species, representing 73% of the total sampled. The abundance was greater in the urban fragment (67.7%, with the diversity index reaching only 25% of the theoretical maximum expected. Probably, these values might have been influenced by the location of this fragment in the urban area, being more homogeneous and submitted directly to the presence of atmospheric pollution. In this manner, X. aromatica is able to shelter a higher diversity of mites when inserted in preserved ecosystems, since the highest diversity of available resources allows the establishment of richer and most diverse mite community.

    Full Text Available Este artigo apresenta uma leitura de José Martí como fonte histórica da educação popular na América Latina. Parte-se do pressuposto de que não pode haver uma verdadeira refundamentação sem o retorno àquilo que sejam momentos, idéias ou princípios fundantes da educação popular. Após situar brevemente o pensamento e a obra de José Martí, caracteriza-se o conceito de educação popular como educação do povo, no sentido de educação universal. Num outro nível, busca-se identificar na obra de Martí traços da educação popular como um movimento político-pedagógico que se configura especialmente a partir da segunda metade do século passado. A premissa é que, num dado momento, educação do povo e educação popular deixam de ser termos equivalentes e que, em José Martí, temos elementos para pensar esses dois termos de forma dialética, num movimento de recriação de uma prática que, embora cindida pelas contingências históricas, é única. São identificados em sua obra quatro princípios da educação popular: a valorização da pluralidade de saberes; a relação interpessoal como ambiente para o aprender-ensinar e base para a transformação social; o conhecimento da realidade a partir de uma perspectiva emancipatória como ato político; e a educação como processo autoformativo da sociedade.This article presents José Martí as a historical source of popular education in Latin America. It starts from the assumption that there can be no true re-foundation without the return to those founding moments, ideas or principles of popular education.

    Null hypothesis significance testing (NHST) is undoubtedly the most common inferential technique used to justify claims in the social sciences. However, even staunch defenders of NHST agree that its outcomes are often misinterpreted. Confidence intervals (CIs) have frequently been proposed as a more useful alternative to NHST, and their use is strongly encouraged in the APA Manual. Nevertheless, little is known about how researchers interpret CIs. In this study, 120 researchers and 442 students-all in the field of psychology-were asked to assess the truth value of six particular statements involving different interpretations of a CI. Although all six statements were false, both researchers and students endorsed, on average, more than three statements, indicating a gross misunderstanding of CIs. Self-declared experience with statistics was not related to researchers' performance, and, even more surprisingly, researchers hardly outperformed the students, even though the students had not received any education on statistical inference whatsoever. Our findings suggest that many researchers do not know the correct interpretation of a CI. The misunderstandings surrounding p-values and CIs are particularly unfortunate because they constitute the main tools by which psychologists draw conclusions from data.

    Biomedical research is seldom done with entire populations but rather with samples drawn from a population. Although we work with samples, our goal is to describe and draw inferences regarding the underlying population. It is possible to use a sample statistic and estimates of error in the sample to get a fair idea of the population parameter, not as a single value, but as a range of values. This range is the confidence interval (CI) which is estimated on the basis of a desired confidence level. Calculation of the CI of a sample statistic takes the general form: CI = Point estimate ± Margin of error, where the margin of error is given by the product of a critical value (z) derived from the standard normal curve and the standard error of point estimate. Calculation of the standard error varies depending on whether the sample statistic of interest is a mean, proportion, odds ratio (OR), and so on. The factors affecting the width of the CI include the desired confidence level, the sample size and the variability in the sample. Although the 95% CI is most often used in biomedical research, a CI can be calculated for any level of confidence. A 99% CI will be wider than 95% CI for the same sample. Conflict between clinical importance and statistical significance is an important issue in biomedical research. Clinical importance is best inferred by looking at the effect size, that is how much is the actual change or difference. However, statistical significance in terms of P only suggests whether there is any difference in probability terms. Use of the CI supplements the P value by providing an estimate of actual clinical effect. Of late, clinical trials are being designed specifically as superiority, non-inferiority or equivalence studies. The conclusions from these alternative trial designs are based on CI values rather than the P value from intergroup comparison.

    The abundance of highly disaggregate data (e.g., at five-second intervals) raises the question of the optimal data interval to estimate advertising carryover. The literature assumes that (1) the optimal data interval is the interpurchase time, (2) too disaggregate data causes a disaggregation bias, and (3) recovery of true parameters requires assumption of the underlying advertising process. In contrast, we show that (1) the optimal data interval is what we call , (2) too disaggregate data do...

    2017-06-01

    Full Text Available We report observations on fur-rubbing with leaves from Piper aduncum by a San Martín titi monkey, Callicebus oenanthe. Fur-rubbing occurred during the transition from the dry to the rainy season in a titi monkey group living in a forest fragment in the Moyobamba region of Peru. Since Piper leaves include very potent compounds that may affect ectoparasites, we tentatively interpret the observed fur-rubbing as self-medication.

  12. Cloning and Characterization of the Genes Encoding the Murine Homologues of the Human Melanoma Antigens MART1 and gp100

    The recent identification of genes encoding melanoma-associated antigens has opened new possibilities for the development of cancer vaccines designed to cause the rejection of established tumors. To develop a syngeneic animal model for evaluating antigen-specific vaccines in cancer therapy, the murine homologues of the human melanoma antigens MART1 and gp 100, which were specifically recognized by tumor-infiltrating lymphocytes from patients with melanoma, were cloned and sequenced from a murine B16 melanoma cDNA library. The open reading frames of murine MART1 and gp 100 encode proteins of 113- and 626-amino acids with 68.8 and 77% identity to the respective human proteins. Comparison of the DNA sequences of the murine MART1 genes, derived from normal melanocytes, the immortalized nontumorgenic melanocyte line Melan-a and the B16 melanoma, showed all to be identical. Northern and Western blot analyses confirmed that both genes encoded products that were melanocyte lineage proteins. Mice immunized with murine MART1 or gp 100 using recombinant vaccinia virus failed to produce any detectable T-cell responses or protective immunity against B16 melanoma. In contrast, immunization of mice with human gp 100 using recombinant adenoviruses elicited T cells specific for hgp100, but these T cells also cross reacted with B16 tumor in vitro and induced significant but weak protection against B16 challenge. Immunization with human and mouse gp100 together [adenovirus type 2 (Ad2)-hep100 plus recombinant vaccinia virus (rVV)-mgp100], or immunization with human gp100 (Ad2-hgp100) and boosting with heterologous vector (rVV-hgp100 or rVV-mgp100) or homologous vector (Ad2-hgp100), did not significantly enhance the protective response against B16 melanoma. These results may suggest that immunization with heterologous tumor antigen, rather than self, may be more effective as an immunotherapeutic reagent in designing antigen-specific cancer vaccines.

    Little is known about the practices for stocking and procuring healthy food in non-traditional food retailers (e.g., gas-marts, pharmacies). The present study aimed to: (i) compare availability of healthy food items across small food store types; and (ii) examine owner/manager perceptions and stocking practices for healthy food across store types. Descriptive analyses were conducted among corner/small grocery stores, gas-marts, pharmacies and dollar stores. Data from store inventories were used to examine availability of twelve healthy food types and an overall healthy food supply score. Interviews with managers assessed stocking practices and profitability. Small stores in Minneapolis and St. Paul, MN, USA, not participating in the Special Supplemental Nutrition Program for Women, Infants, and Children. One hundred and nineteen small food retailers and seventy-one store managers. Availability of specific items varied across store type. Only corner/small grocery stores commonly sold fresh vegetables (63% v. 8% of gas-marts, 0% of dollar stores and 23% of pharmacies). More than half of managers stocking produce relied on cash-and-carry practices to stock fresh fruit (53%) and vegetables (55%), instead of direct store delivery. Most healthy foods were perceived by managers to have at least average profitability. Interventions to improve healthy food offerings in small stores should consider the diverse environments, stocking practices and supply mechanisms of small stores, particularly non-traditional food retailers. Improvements may require technical support, customer engagement and innovative distribution practices.

(Combretaceae and of its aqueous (TFAqF, hydroalcoholic (TFHAF, and hexanic (TFHEXF partition fractions have been evaluated. TFEE presented low acute toxicity, antioxidant, and antiulcerogenic activity against ethanol-induced ulcers, which was partially blocked by pretreatment with L-NAME and indomethacin. It reduced the total acidity and raised the pH of gastric secretion. Additionally, TFEE delayed gastric emptying and slightly inhibited the small intestinal transit and also presented a weakly antidiarrheal activity. The antiulcerogenic and antioxidant activity were also detected in TFAqF and TFHAF but not in TFHEXF. The antisecretory and gastroprotective activity of TFEE partially involve the nitric oxide and prostaglandin participation. Nevertheless, TFEE, TFAqF, and TFHAF drastically reduced the mucus layer adhered to the gastric wall of rats treated with ethanol or indomethacin. Complementary studies are required in order to clarify the paradox of the presence of a gastroprotector activity in this plant that, at the same time, reduces the mucus layer adhered to the gastric wall.

    Full Text Available Considering the potential and importance of biodiversity of the Caatinga biome, studies on endemic species are relevant to conservation of its natural resources. The objectives of this work was to evaluate seed viability and physical methods for overcoming seed dormancy in juazeiro (Ziziphus joazeiro Mart. and assess the influence of different types of soil on the initial growth of juazeiro plants. The experiments were conducted in three stages. In the first stage, the viability of seeds from different lots was evaluated using the tetrazolium test. The second stage was conducted in a plant nursery, evaluating the application of physical processes (scarification with sandpaper and hammer in overcoming seed dormancy, and the initial growth of the plants. In the third step, the chlorophyll a and b contents, gas exchange and dry matter accumulation were evaluated in young juazeiro plants in three types of soil (Oxisol, Entisol and Vertisol. The results indicate that the viability of juazeiro seeds is greatly influenced by differences between the progenitor plants and by storage conditions, which enable a longevity of two years when stored at 22°C and 16% of relative humidity. The scarification methods with sandpaper and hammer are not efficient to reduce the time and uniform seed germination. The juazeiro plants have high growth potential in different edaphic environments, adapting well to soils of different textures and chemical compositions.

    Full Text Available Abstract The family Leguminosae comprises approximately 20,000 species that mostly form symbioses with arbuscular mycorrhizal fungi (AMF and nitrogen-fixing bacteria (NFB. This study is aimed at investigating and confirming the dependence on nodulation and biological nitrogen fixation in the specie Piptadenia gonoacantha (Mart. Macbr., which belongs to the Piptadenia group. Two consecutive experiments were performed in a greenhouse. The experiments were fully randomized with six replicates and a factorial scheme. For the treatments, the two AMF species and three NFB strains were combined to nodulate P. gonoacantha in addition to the control treatments. The results indicate this species’ capacity for nodulation without the AMF; however, the AMF + NFB combinations yielded a considerable gain in P. gonoacantha shoot weight compared with the treatments that only included inoculating with bacteria or AMF. The results also confirm that the treatment effects among the AMF + NFB combinations produced different shoot dry weight/root dry weight ratios. We conclude that AMF is not necessary for nodulation and that this dependence improves species development because plant growth increases upon co-inoculation.

    Aquatic macrophytes were found to be the potential scavengers of heavy metals from aquatic environment. In this study, several physiological responses of Alternanthera philoxeroides (Mart.) Griseb leaves to elevated concentrations of cadmium (up to 10 mM) were investigated. It was found that A. philoxeroides was able to accumulate cadmium in its leaves. The pigment contents decreased with the increase of the Cd concentrations. The Cd could induce rise of the activity of peroxidase (POD) at lower concentration (<5 mM), however, when the concentration of Cd rose up to 10 mM, the POD activity declined. The changes of superoxide dismutase (SOD) and Catalase (CAT) activities were exactly opposite to that of POD. In the leaves of Cd-treated fronds, the amounts of three polypeptides with apparent molecular weights 80, 39 and 28 kDa, respectively, were became visible in SDS-PAGE. The nature of these polypeptides remains to be determined. - Cd modified a number of physiological processes and particularly chlorophyll degradation

    Full Text Available In order to validate the Bumelia sartorum Mart., Sapotaceae, traditional use for infection diseases, this study evaluates the antibacterial activity of the stem bark fractions against methicillin-sensitive (MSSA and methicillin-resistant (MRSA Staphylococcus aureus strains by using the agar dilution method and reported as MIC (minimal inhibitory concentration. In addition, the DPPH scavenging activity of these fractions was measured and the chemical composition and acute toxicity of the active fraction were also determined. The ethyl acetate (EtOAc extract was chemically analyzed by LC/MS, direct ionization APCI/MS, ¹H NMR and 13C-NMR. All fractions, except butanol extract, presented high antioxidant activity, especially the methanol and the EtOAc extracts, which showed EC50 values (5.67 and 5.30 µg/mL, respectively considerably lower than the Gingko-standard EGb 761® (38.58 µg/mL. The antibacterial activity against S. aureus strains was observed in EtOAc (MIC 256-512 µg/mL, which showed a very low toxicity. The chemical study of this fraction revealed the abundant presence of polyphenolic compounds. The antibacterial and antioxidant activities reported in this paper for EtOAc extract from B. sartorum and the low toxicity of this fraction opens the possibility that it could be helpful for the developing of new antibacterial agents for treating S. aureus infections.

    Full Text Available Abstract Salacia crassifolia (Mart. Ex. Schult. G. Don. is a bush which belongs to Celastraceae family and occurs specially in Brazilian Cerrado. Its leaves, stem, seeds and fruits are popularly used for several medicinal purposes, such as antitumoral, antirheumatic, anti-inflammatory and antimicrobial. In this study, the mutagenic and antimutagenic activities of S. crassifolia stem bark fractions (hexane, ethyl acetate and hydroalcoholic were evaluated by the Ames mutagenicity assay in Salmonella typhimurium TA98 and TA100 strains. By the obtained results, all S. crassifolia fractions did not significantly increase the number of prototrophic revertants for histidine (His+ in both S. typhimurium strains tested (p > 0.05, suggesting absence of mutagenicity. Regarding antimutagenicity, the fractions ethyl acetate and hydroalcoholic significantly decreased the number of His+ revertants colonies induced by positive control for strain TA98 (p < 0.05, demonstrating protection against mutagenicity induced by 4-nitroquinolile1-oxide, whereas the hexane fraction did not show antimutagenic effect in this strain. In the TA100 strain, all fractions of S. crassifolia protected DNA against the harmful action of sodium azide, and the hexane fraction exhibited the greatest protection in this work. Thus, it’s possible conclude that the fractions of S. crassifolia tested in this study could be used in chemoprevention.

    The tucuma (Astrocaryum vulgare Mart.) is a native fruit of Amazonia, occurring mainly in the state of Para, but also found in the Brazilian northeast states and in the Brazilian central-western states. The tucuma is considered an excellent source of carotenoids with a very high concentration of β-carotene, which is a precursor of vitamin A. In addition to carotenoids it is an important source of vitamin B2 (riboflavin) in fruits. This study aimed to analyze the effects of gamma radiation on the nutritional value of tucuma. The fruits were irradiated at doses of 0.5, 1.0 and 2.0 kGy irradiator with a source of cesium 137. The carotenoids were determined by spectrophotometry. The analysis of α and β-carotene, thiamine, riboflavin were carried out by high performance liquid chromatography (HPLC). The β-carotene accounts for 80% of total carotenoids in tucuma, and with a dose of 2 kGy, it showed the highest reduction of β-carotene, about 7.5% in relation to the control. The tucuma fruit showed high levels of riboflavin from 0.183 to 0.222 μg 100 g -1 , and maintained stability after the gamma radiation process. However, it had low levels of thiamine from 0.050 to 0.033 μg 100 g -1 , and irradiated at a dose of 2 kGy showed significant reductions of thiamine, about 34% in relation to the control. (author)

  1. Probability Distribution for Flowing Interval Spacing

    International Nuclear Information System (INIS)

    Kuzio, S.

    2001-01-01

    The purpose of this analysis is to develop a probability distribution for flowing interval spacing. A flowing interval is defined as a fractured zone that transmits flow in the Saturated Zone (SZ), as identified through borehole flow meter surveys (Figure 1). This analysis uses the term ''flowing interval spacing'' as opposed to fractured spacing, which is typically used in the literature. The term fracture spacing was not used in this analysis because the data used identify a zone (or a flowing interval) that contains fluid-conducting fractures but does not distinguish how many or which fractures comprise the flowing interval. The flowing interval spacing is measured between the midpoints of each flowing interval. Fracture spacing within the SZ is defined as the spacing between fractures, with no regard to which fractures are carrying flow. The Development Plan associated with this analysis is entitled, ''Probability Distribution for Flowing Interval Spacing'', (CRWMS M and O 2000a). The parameter from this analysis may be used in the TSPA SR/LA Saturated Zone Flow and Transport Work Direction and Planning Documents: (1) ''Abstraction of Matrix Diffusion for SZ Flow and Transport Analyses'' (CRWMS M and O 1999a) and (2) ''Incorporation of Heterogeneity in SZ Flow and Transport Analyses'', (CRWMS M and O 1999b). A limitation of this analysis is that the probability distribution of flowing interval spacing may underestimate the effect of incorporating matrix diffusion processes in the SZ transport model because of the possible overestimation of the flowing interval spacing. Larger flowing interval spacing results in a decrease in the matrix diffusion processes. This analysis may overestimate the flowing interval spacing because the number of fractures that contribute to a flowing interval cannot be determined from the data. Because each flowing interval probably has more than one fracture contributing to a flowing interval, the true flowing interval spacing could be

  2. Correct Bayesian and frequentist intervals are similar

    1986-01-01

    This paper argues that Bayesians and frequentists will normally reach numerically similar conclusions, when dealing with vague data or sparse data. It is shown that both statistical methodologies can deal reasonably with vague data. With sparse data, in many important practical cases Bayesian interval estimates and frequentist confidence intervals are approximately equal, although with discrete data the frequentist intervals are somewhat longer. This is not to say that the two methodologies are equally easy to use: The construction of a frequentist confidence interval may require new theoretical development. Bayesians methods typically require numerical integration, perhaps over many variables. Also, Bayesian can easily fall into the trap of over-optimism about their amount of prior knowledge. But in cases where both intervals are found correctly, the two intervals are usually not very different. (orig.)

    A generic method for the providing of prediction intervals of wind power generation is described. Prediction intervals complement the more common wind power point forecasts, by giving a range of potential outcomes for a given probability, their so-called nominal coverage rate. Ideally they inform...... on the characteristics of prediction errors for providing conditional interval forecasts. By simultaneously generating prediction intervals with various nominal coverage rates, one obtains full predictive distributions of wind generation. Adapted resampling is applied here to the case of an onshore Danish wind farm...... to the case of a large number of wind farms in Europe and Australia among others is finally discussed....

  11. Expressing Intervals in Automated Service Negotiation

    Science.gov (United States)

    Clark, Kassidy P.; Warnier, Martijn; van Splunter, Sander; Brazier, Frances M. T.

    During automated negotiation of services between autonomous agents, utility functions are used to evaluate the terms of negotiation. These terms often include intervals of values which are prone to misinterpretation. It is often unclear if an interval embodies a continuum of real numbers or a subset of natural numbers. Furthermore, it is often unclear if an agent is expected to choose only one value, multiple values, a sub-interval or even multiple sub-intervals. Additional semantics are needed to clarify these issues. Normally, these semantics are stored in a domain ontology. However, ontologies are typically domain specific and static in nature. For dynamic environments, in which autonomous agents negotiate resources whose attributes and relationships change rapidly, semantics should be made explicit in the service negotiation. This paper identifies issues that are prone to misinterpretation and proposes a notation for expressing intervals. This notation is illustrated using an example in WS-Agreement.

    OBJECTIVES: To categorize interval cancers, and thus identify false-negatives, following prevalent and incident screens in the Welsh breast screening programme. SETTING: Breast Test Wales (BTW) Llandudno, Cardiff and Swansea breast screening units. METHODS: Five hundred and sixty interval breast cancers identified following negative mammographic screening between 1989 and 1997 were reviewed by eight screening radiologists. The blind review was achieved by mixing the screening films of women who subsequently developed an interval cancer with screen negative films of women who did not develop cancer, in a ratio of 4:1. Another radiologist used patients' symptomatic films to record a reference against which the reviewers' reports of the screening films were compared. Interval cancers were categorized as 'true', 'occult', 'false-negative' or 'unclassified' interval cancers or interval cancers with minimal signs, based on the National Health Service breast screening programme (NHSBSP) guidelines. RESULTS: Of the classifiable interval films, 32% were false-negatives, 55% were true intervals and 12% occult. The proportion of false-negatives following incident screens was half that following prevalent screens (P = 0.004). Forty percent of the seed films were recalled by the panel. CONCLUSIONS: Low false-negative interval cancer rates following incident screens (18%) versus prevalent screens (36%) suggest that lower cancer detection rates at incident screens may have resulted from fewer cancers than expected being present, rather than from a failure to detect tumours. The panel method for categorizing interval cancers has significant flaws as the results vary markedly with different protocol and is no more accurate than other, quicker and more timely methods.

    Semantic text annotation enables the association of semantic information (ontology concepts) to text expressions (terms), which are readable by software agents. In the scientific scenario, this is particularly useful because it reveals a lot of scientific discoveries that are hidden within academic articles. The Biomedical area has more than 300 ontologies, most of them composed of over 500 concepts. These ontologies can be used to annotate scientific papers and thus, facilitate data extraction. However, in the context of a scientific research, a simple keyword-based query using the interface of a digital scientific texts library can return more than a thousand hits. The analysis of such a large set of texts, annotated with such numerous and large ontologies, is not an easy task. Therefore, the main objective of this work is to provide a method that could facilitate this task. This work describes a method called Text and Ontology ETL (TOETL), to build an analytical view over such texts. First, a corpus of selected papers is semantically annotated using distinct ontologies. Then, the annotation data is extracted, organized and aggregated into the dimensional schema of a data mart. Besides the TOETL method, this work illustrates its application through the development of the TaP DM (Target Prioritization data mart). This data mart has focus on the research of gene essentiality, a key concept to be considered when searching for genes showing potential as anti-infective drug targets. This work reveals that the proposed approach is a relevant tool to support decision making in the prioritization of new drug targets, being more efficient than the keyword-based traditional tools.

    Full Text Available Este artículo estudia los llamados Diarios del poeta José Lezama Lima, que recogen anotaciones suyas entre los años 1939-1949 y entre 1956-1958, para analizar cómo se refleja en ambos textos el interés por la poesía y la reflexión acerca de la misma. Sus anotaciones son comparadas con las de José Martí, percibiendo que mientras que la poesía era para Martí la forma suprema de la literatura, para Lezama llegó a ser un método de conocimiento de la realidad, la categoría central a la que conduce su pensamiento estético. Se pretende demostrar además cómo Lezama parte de las ideas de Martí sobre la poesía para llegar a tener ideas propias y luego trascendentes.   This article studies what are known as the Diaries of poet José Lezama Lima, in which his notes taken between 1939-1949 and 1956-1958 are gathered in order to analyze how both texts reflect his interest towards poetry as well as his reflections about it. His notes are compared with those of José Martí, revealing the fact that whereas for Martí, poetry was the supreme manifestation of literature; Lezama saw it as a method for acquiring knowledge of reality, the central category to which his aesthetic thinking leads. An attempt is made to further showcase the fact that Lezama starts off with Martí's ideas about poetry in order to later develop his own, which would at a later date become transcendental.

    Full Text Available Catolé Palm (Syagrus oleracea Mart Fruits were analysed for their chemical composition. The pulp and kernel portions contained 0.7 and 40.0% lipids. Freshly extracted kernel oil showed a small concentration (0.4 meq/kg of peroxides but did not contain free fatty acids. The iodine and saponification values were 27.4 and 226, respectively. A large qualitative as well as quantitative difference in the fatty acid composition between the catolé pulp and kernel oil was observed. Fifteen and 19 fatty acids were identified in the pulp and kernel oil, respectively. These oils contained 48.9 and 73.2 % saturated fatty acids. The principal saturated fatty acids of the pulp oil was palmitic (C16 acid, while that of kernel oil was lauric (C12 acid. Oleic acid was the main monounsaturated fatty acid in both oils. In pulp oil, linoleic (C18:2 and linolenic (C18:3 were present at 23.5 and 11,3% concentrations, while kernel oil contained only linoleic acid (3.59%. In relation to amino acid composition of proteins, pulp proteins presented better amino acid profile than kernel proteins. In pulp proteins, the essential amino acids were present at concentrations higher than recommended by FAO except for methionine and lysine, while kernel proteins were deficient in all essential amino acids except phenylalanine, isoleucine and threonine.Los frutos de la Palmera catolé (Syagrus oleracea Mart fueron analizados para determinar su composición química.

    The bacaba (Oenocarpus bacaba Mart.) is a fruit originating from the Amazon forest, and its oil has similarity to the fatty acid composition of olive oil. The objective of this study was to evaluate the quality of bacaba oil submitted to gamma radiation in the of 5, 10 and 15 kGy. The extracted oil was irradiated at doses of 5, 10 and 15 kGy, and then the physical and chemical analysis were carried out: acid value, peroxide value, iodine value, refractive index, specific gravity, saponification value, coefficient specific extinction at 232 and 270 nm and color. Was possible to evidence that radiation promoted decrease in acidity of the oil 26.67%, 27.27% and 9.09%, respectively, at the doses of 5, 10 and 15 kGy, in relation to oil which has not gone through the process (standard). The values of specific gravity, refractive index and saponification value, have not changed, but the result of peroxides were significantly affected, increasing by 51.99%, 100.44% and 89.40% values relative to the standard. It was also observed a significant increase in K232 and K270 values, suggesting increased oxidation products, conjugated dienes and trienes. The oil color has been affected by the doses, generating a product with a more yellowish color and increased brightness. That way, from the analysis, it concluded that the use of gamma radiation at the doses used were not sufficient to make it, in the short term, unsafe for consumption, but changed substantially oil color.

    Full Text Available Huge lobate deposits called aureoles are covering the base of the giant Martian volcanic constructs of Tharsis dome. The origin of these structures has been a matter of debate between two competing hypotheses: volcanic landslides or mountain glaciers. Here we consider the most important of the aureoles, near Arsia Mons, concluding that the glacier model explains best the deposit features, such as the layering, the ridges (interpreted as glaciotectonic ones, and the lobated terrain. We then discuss the fit of these proposed glacier deposits in the present paleoclimatic Martian models. The aureoles could be key elements in the confirmation of the «Baker cycle» model of repeated episodes of temperate, humid, sea-dominated climates coincident in time with the outflow channels activity.Al pie de los grandes volcanes marcianos del domo de Tharsis aparecen unas formas lobuladas que han recibido el nombre de aureolas. El origen de estas estructuras ha sido objeto de un largo debate entre dos hipótesis principales que las interpretan como deslizamientos de ladera o como glaciares de montaña. En este trabajo se estudia la mejor desarrollada de estas aureolas, la de Arsia Mons, llegándose a la conclusión de que la hipótesis glaciar explica mejor las características del depósito, y en concreto la existencia de estratificación, las crestas (que se interpretan como glaciotectónicas y los terrenos lobulados. Por último se discute la conexión de estos depósitos con los modelos paleoclimáticos actuales sobre Marte, lo que lleva a la conclusión de que las aureolas deben ser depósitos glaciares recientes relacionados con repetidos episodios de clima cálido (ciclos de Baker, provocados por la acción de los canales de desbordamiento.

Antes que una utopía a denunciar desde una visión “realista”, se trata de construir una economía que combine mecanismos de mercado regulados socio-políticamente y relaciones de reciprocidad y redistribución.

The author maintains that the social and solidarity economy is a sphere under construction, in which several strands can be found. All of these approaches aim to move towards a different type of economy. This character as a developing realm can prompt doubts; this, however, should not lead to a paralyzing fatalism which allows the constant updating of the free market as a hegemonic institution. Far from a utopia to be denounced from a “realistic” viewpoint of economy, its concerns the construction of an economy that combines socio-politically regulated market mechanisms as well as relations of reciprocity and redistribution. The text also explores some of the elements that make up the solidarity and social economy.

    Little is known about customer purchases of foods and beverages from small and non-traditional food retailers (i.e. corner stores, gas-marts, dollar stores and pharmacies). The present study aimed to: (i) describe customer characteristics, shopping frequency and reasons for shopping at small and non-traditional food retailers; and (ii) describe food/beverage purchases and their nutritional quality, including differences across store type. Data were collected through customer intercept interviews. Nutritional quality of food/beverage purchases was analysed; a Healthy Eating Index-2010 (HEI-2010) score for purchases was created by aggregating participant purchases at each store. Small and non-traditional food stores that were not WIC-authorized in Minneapolis and St. Paul, MN, USA. Customers (n 661) from 105 food retailers. Among participants, 29 % shopped at the store at least once daily; an additional 44 % shopped there at least once weekly. Most participants (74 %) cited convenient location as the primary draw to the store. Customers purchased a median of 2262 kJ (540 kcal), which varied by store type (P=0·04). The amount of added sugar far surpassed national dietary recommendations. At dollar stores, participants purchased a median of 5302 kJ (1266 kcal) for a median value of $US 2·89. Sugar-sweetened beverages were the most common purchase. The mean HEI-2010 score across all stores was 36·4. Small and non-traditional food stores contribute to the urban food environment. Given the poor nutritional quality of purchases, findings support the need for interventions that address customer decision making in these stores.

  10. INTERVAL OBSERVER FOR A BIOLOGICAL REACTOR MODEL

    Directory of Open Access Journals (Sweden)

    T. A. Kharkovskaia

    2014-05-01

    Full Text Available The method of an interval observer design for nonlinear systems with parametric uncertainties is considered. The interval observer synthesis problem for systems with varying parameters consists in the following. If there is the uncertainty restraint for the state values of the system, limiting the initial conditions of the system and the set of admissible values for the vector of unknown parameters and inputs, the interval existence condition for the estimations of the system state variables, containing the actual state at a given time, needs to be held valid over the whole considered time segment as well. Conditions of the interval observers design for the considered class of systems are shown. They are: limitation of the input and state, the existence of a majorizing function defining the uncertainty vector for the system, Lipschitz continuity or finiteness of this function, the existence of an observer gain with the suitable Lyapunov matrix. The main condition for design of such a device is cooperativity of the interval estimation error dynamics. An individual observer gain matrix selection problem is considered. In order to ensure the property of cooperativity for interval estimation error dynamics, a static transformation of coordinates is proposed. The proposed algorithm is demonstrated by computer modeling of the biological reactor. Possible applications of these interval estimation systems are the spheres of robust control, where the presence of various types of uncertainties in the system dynamics is assumed, biotechnology and environmental systems and processes, mechatronics and robotics, etc.

    The aim of this study was to investigate a technique for improving the performance of Magnetic Resonance Fingerprinting (MRF) in repetitive sampling schemes, in particular for 3D MRF acquisition, by shortening relaxation intervals between MRF pulse train repetitions. A calculation method for MRF dictionaries adapted to short relaxation intervals and non-relaxed initial spin states is presented, based on the concept of stationary fingerprints. The method is applicable to many different k-space sampling schemes in 2D and 3D. For accuracy analysis, T 1 and T 2 values of a phantom are determined by single-slice Cartesian MRF for different relaxation intervals and are compared with quantitative reference measurements. The relevance of slice profile effects is also investigated in this case. To further illustrate the capabilities of the method, an application to in-vivo spiral 3D MRF measurements is demonstrated. The proposed computation method enables accurate parameter estimation even for the shortest relaxation intervals, as investigated for different sampling patterns in 2D and 3D. In 2D Cartesian measurements, we achieved a scan acceleration of more than a factor of two, while maintaining acceptable accuracy: The largest T 1 values of a sample set deviated from their reference values by 0.3% (longest relaxation interval) and 2.4% (shortest relaxation interval). The largest T 2 values showed systematic deviations of up to 10% for all relaxation intervals, which is discussed. The influence of slice profile effects for multislice acquisition is shown to become increasingly relevant for short relaxation intervals. In 3D spiral measurements, a scan time reduction of 36% was achieved, maintaining the quality of in-vivo T1 and T2 maps. Reducing the relaxation interval between MRF sequence repetitions using stationary fingerprint dictionaries is a feasible method to improve the scan efficiency of MRF sequences. The method enables fast implementations of 3D spatially

    1994-01-01

    Attractor reconstruction from interspike interval (ISI) data is described, in rough analogy with Taken's theorem for attractor reconstruction from time series. Assuming a generic integrate-and-fire model coupling the dynamical system to the spike train, there is a one-to-one correspondence between the system states and interspike interval vectors of sufficiently large dimension. The correspondence has an important implication: interspike intervals can be forecast from past history. We show that deterministically driven ISI series can be distinguished from stochastically driven ISI series on the basis of prediction error

    2008-08-28

    While progress has been made in determining the molecular basis for the circadian clock, the mechanism by which mammalian brains time intervals measured in seconds to minutes remains a mystery. An obvious question is whether the interval-timing mechanism shares molecular machinery with the circadian timing mechanism. In the current study, we trained circadian CLOCK +/- and -/- mutant male mice in a peak-interval procedure with 10 and 20-s criteria. The mutant mice were more active than their wild-type littermates, but there were no reliable deficits in the accuracy or precision of their timing as compared with wild-type littermates. This suggests that expression of the CLOCK protein is not necessary for normal interval timing.

    2010-06-01

    We study the statistical properties of the recurrence intervals τ between successive trading volumes exceeding a certain threshold q. The recurrence interval analysis is carried out for the 20 liquid Chinese stocks covering a period from January 2000 to May 2009, and two Chinese indices from January 2003 to April 2009. Similar to the recurrence interval distribution of the price returns, the tail of the recurrence interval distribution of the trading volumes follows a power-law scaling, and the results are verified by the goodness-of-fit tests using the Kolmogorov-Smirnov (KS) statistic, the weighted KS statistic and the Cramér-von Mises criterion. The measurements of the conditional probability distribution and the detrended fluctuation function show that both short-term and long-term memory effects exist in the recurrence intervals between trading volumes. We further study the relationship between trading volumes and price returns based on the recurrence interval analysis method. It is found that large trading volumes are more likely to occur following large price returns, and the comovement between trading volumes and price returns is more pronounced for large trading volumes.

  1. Interval Size and Affect: An Ethnomusicological Perspective

    2013-08-01

    Full Text Available This commentary addresses Huron and Davis's question of whether "The Harmonic Minor Provides an Optimum Way of Reducing Average Melodic Interval Size, Consistent with Sad Affect Cues" within any non-Western musical cultures. The harmonic minor scale and other semitone-heavy scales, such as Bhairav raga and Hicaz makam, are featured widely in the musical cultures of North India and the Middle East. Do melodies from these genres also have a preponderance of semitone intervals and low incidence of the augmented second interval, as in Huron and Davis's sample? Does the presence of more semitone intervals in a melody affect its emotional connotations in different cultural settings? Are all semitone intervals equal in their effect? My own ethnographic research within these cultures reveals comparable connotations in melodies that linger on semitone intervals, centered on concepts of tension and metaphors of falling. However, across different musical cultures there may also be neutral or lively interpretations of these same pitch sets, dependent on context, manner of performance, and tradition. Small pitch movement may also be associated with social functions such as prayer or lullabies, and may not be described as "sad." "Sad," moreover may not connote the same affect cross-culturally.

    A field prototype of an antibody array-based life-detector instrument, Signs Of LIfe Detector (SOLID2), has been tested in a Mars drilling mission simulation called MARTE (Mars Astrobiology Research and Technology Experiment). As one of the analytical instruments on the MARTE robotic drilling rig, SOLID2 performed automatic sample processing and analysis of ground core samples (0.5 g) with protein microarrays that contained 157 different antibodies. Core samples from different depths (down to 5.5 m) were analyzed, and positive reactions were obtained in antibodies raised against the Gram-negative bacterium Leptospirillum ferrooxidans, a species of the genus Acidithiobacillus (both common microorganisms in the Río Tinto area), and extracts from biofilms and other natural samples from the Río Tinto area. These positive reactions were absent when the samples were previously subjected to a high-temperature treatment, which indicates the biological origin and structural dependency of the antibody-antigen reactions. We conclude that an antibody array-based life-detector instrument like SOLID2 can detect complex biological material, and it should be considered as a potential analytical instrument for future planetary missions that search for life.

    T cells engineered to express TCRs specific for tumor Ags can drive cancer regression. The first TCRs used in cancer gene therapy, DMF4 and DMF5, recognize two structurally distinct peptide epitopes of the melanoma-associated MART-1/Melan-A protein, both presented by the class I MHC protein HLA-A*0201. To help understand the mechanisms of TCR cross-reactivity and provide a foundation for the further development of immunotherapy, we determined the crystallographic structures of DMF4 and DMF5 in complex with both of the MART-1/Melan-A epitopes. The two TCRs use different mechanisms to accommodate the two ligands. Although DMF4 binds the two with a different orientation, altering its position over the peptide/MHC, DMF5 binds them both identically. The simpler mode of cross-reactivity by DMF5 is associated with higher affinity toward both ligands, consistent with the superior functional avidity of DMF5. More generally, the observation of two diverging mechanisms of cross-reactivity with the same Ags and the finding that TCR-binding orientation can be determined by peptide alone extend our understanding of the mechanisms underlying TCR cross-reactivity.

    Full Text Available Eichhornia crassipes (Mart. Solms is an aquatic invasive weed throughout the tropical and subtropical regions of the world. The plant rarely produces any fruit under natural condition In order to understand the causes of failure of seed set in this plant various aspect of pollen biology were studied. Pollen fertility and pollen viability was assessed using Muntzing� s mixture and in acetic orcein and TTZ, while pollen germination was assessed with different concentrations of sucrose supplemented with boric acid and Ca and Mg salts. The aim of present study was to find out the cause of sexual incompatibility of Eichhornia crassipes (Mart. Solms. In spite of high pollen fertility, pollen viability and pollen germination the species show hardly any fruit set under natural condition. The abnormal pollen germination like curling of pollen tubes, shrinkage of pollen tube tips and bending of pollen tube might be reasons of sexual incompatibility of this species. It is observed that the taxa required comparatively low sucrose concentration (5% for their optimal in vitro pollen germination (54.08%. Boric acid to certain extent also influences the in vitro pollen germination (56.2%. In the present investigation the nature of substrate in association with the effect of Boric acid, CaCO3, MgSO4 on the in vitro pollen germination of Eichhornia crassipes is also worked out. However the tested salts show no significant effect on pollen germination in the present study.

    The popularization of antique collecting is typically located in the second half of the twentieth century, with the rise of 'retrochic' and the emergence of new markets and online trading websites for anonymously exchanging second-hand goods. Close study of the printed literature connected with the inter-war second-hand trade, however, challenges conventional chronologies in the history of consumer culture, and can provide a new perspective on the role of collecting in British social and cultural life. This article examines the period, after the late 1920s, during which The Bazaar, Exchange and Mart reinvented itself as a forum for antique and decorative art enthusiasts. It argues that, in speaking to and publishing contributions from so-called 'small collectors', this 'Popular Weekly for Collectors and Connoisseurs' helped shape a modern and democratic culture of art appreciation in which ordinary people were actively invited to participate. The private correspondence archive of a Buckinghamshire subscriber who used the Exchange and Mart to sell his collection of 'Egyptian, Greek, and Roman Antiquities' to readers across the country during the 1930s reveals an intimate portrait of the desires, fantasies, and pleasures associated with the popular experience of collecting in pre-war Britain. © The Author [2016].

    Fracture spacing is a key hydrologic parameter in analyses of matrix diffusion. Although the individual fractures that transmit flow in the saturated zone (SZ) cannot be identified directly, it is possible to determine the fractured zones that transmit flow from flow meter survey observations. The fractured zones that transmit flow as identified through borehole flow meter surveys have been defined in this report as flowing intervals. The flowing interval spacing is measured between the midpoints of each flowing interval. The determination of flowing interval spacing is important because the flowing interval spacing parameter is a key hydrologic parameter in SZ transport modeling, which impacts the extent of matrix diffusion in the SZ volcanic matrix. The output of this report is input to the ''Saturated Zone Flow and Transport Model Abstraction'' (BSC 2004 [DIRS 170042]). Specifically, the analysis of data and development of a data distribution reported herein is used to develop the uncertainty distribution for the flowing interval spacing parameter for the SZ transport abstraction model. Figure 1-1 shows the relationship of this report to other model reports that also pertain to flow and transport in the SZ. Figure 1-1 also shows the flow of key information among the SZ reports. It should be noted that Figure 1-1 does not contain a complete representation of the data and parameter inputs and outputs of all SZ reports, nor does it show inputs external to this suite of SZ reports. Use of the developed flowing interval spacing probability distribution is subject to the limitations of the assumptions discussed in Sections 5 and 6 of this analysis report. The number of fractures in a flowing interval is not known. Therefore, the flowing intervals are assumed to be composed of one flowing zone in the transport simulations. This analysis may overestimate the flowing interval spacing because the number of fractures that contribute to a flowing interval cannot be

    A recent California study reported increased risk of autistic disorder in children conceived within a year after the birth of a sibling. We assessed the association between interpregnancy interval and risk of autistic disorder using nationwide registry data on pairs of singleton full siblings born in Norway. We defined interpregnancy interval as the time from birth of the first-born child to conception of the second-born child in a sibship. The outcome of interest was autistic disorder in the second-born child. Analyses were restricted to sibships in which the second-born child was born in 1990-2004. Odds ratios (ORs) were estimated by fitting ordinary logistic models and logistic generalized additive models. The study sample included 223,476 singleton full-sibling pairs. In sibships with interpregnancy intervals autistic disorder, compared with 0.13% in the reference category (≥ 36 months). For interpregnancy intervals shorter than 9 months, the adjusted OR of autistic disorder in the second-born child was 2.18 (95% confidence interval 1.42-3.26). The risk of autistic disorder in the second-born child was also increased for interpregnancy intervals of 9-11 months in the adjusted analysis (OR = 1.71 [95% CI = 1.07-2.64]). Consistent with a previous report from California, interpregnancy intervals shorter than 1 year were associated with increased risk of autistic disorder in the second-born child. A possible explanation is depletion of micronutrients in mothers with closely spaced pregnancies.

    Full Text Available The açai palm tree (Euterpe oleracea Mart. is native to the Amazonian estuary. Media revelation of the nutraceutical properties of açai palm has resulted in its introduction in the national and international markets, consequently increasing the açai palm crop area in the Amazon. Nevertheless, açai palm cultivation is performed in a rational manner, because of limited product extraction from the native açai palm varieties. The study aimed to conduct a preliminary estimate of genetic variability, parameters, and phenotypic divergence of parent açai palms. Data from 129 parent plants from northeast Pará was collected. Analysis of variance (ANOVA of 22 morphoagronomic traits was performed to estimate the genetic parameters. Divergence was estimated using standardized average euclidean distance by using unweighted pair group method with arithmetic mean (UPGMA and Tocher clustering methods. Significant variance was noted in 77.3% traits (ANOVA, p<0.01 and p<0.05; CVg/CVe ratio indicated that 72.3% traits may present genetic variability for use in breeding programs. The euclidean distance showed EO-070 and EO-072 parent plants (Combu Island as the least divergent, and EO-010 (Belém and EO-018 (Salinópolis as the most divergent. The clustering methods determined ten (Tocher and nine (UPGMA similar groups. The most dissimilar parent plants were EO-035 (Capitão Poço, EO- 109 (Combu Island, EO-019 (Salinópolis, and EO-010 (Belém (Tocher method, whereas even the EO-010 (Belém; EO-011 (São João de Pirabas; EO-017, EO-018, and EO-019 (Salinópolis; EO-062 and EO-109 (Combu Island plants showed dissimilarity. We concluded that the 129 mother plants have high phenotypic variability, indicating the possibility of their use in genetic breeding programs. Further, the divergent parent plants can be used in the production of genotypes with favorable characteristics.

    Full Text Available The effects on performance and digestibility in growing rabbits were studied by comparing 3 diets containing increasing inclusion rates of amaranth (Amaranthus dubius Mart. ex Thell.: 0 (A0, 160 (A16 and 320 g/kg (A32 diet. Diets were formulated isoproteic and isocaloric to meet the nutrient requirements of growing rabbits. One hundred and thirteen weaned New Zealand White rabbits (mean±standard deviation weight: 760±102 g, individually caged, were randomly assigned to one of the 3  experimental diets. Rabbits were fed ad libitum from 35 to 87 d of age, and health status and performance traits were  onitored. The coefficients of total tract apparent digestibility of the diets were measured between 42 and 46 d of age in 12 rabbits per treatment. Amaranthus dubius contained 209 g/kg dry matter (DM of crude protein and 398 g/kg DM of neutral detergent fibre. There were no significant differences between treatments in weight gain (mean 21.6 g/d and live weight at the end of the fattening period (mean 1883 g. Daily feed intake was higher (P<0.05 in A0 than in A16 and A32 diets (85.4 vs. 73.7 and 69.9 g/d, respectively, and feed conversion rate improved with increased inclusion of A. dubius in the diet (from 3.84 to 3.28 for A0 and A32 diets, respectively; P<0.05. Health status was not affected by the amaranth inclusion rate. Total tract apparent digestibility showed high values, with no differences among diets except for ether extract. Thus, A. dubius could be considered as an alternative source of protein and fibre for rabbit feeding in tropical and subtropical regions.

    Electric utilities are facing the need for additional generating capacity, new transmission systems and more efficient use of existing resources. As such, there are several uncertainties associated with utility decisions. These uncertainties include future load growth, construction times and costs, and performance of new resources. Regulatory and economic environments also present uncertainties. Uncertainty can be modeled based on a probabilistic approach where probability distributions for all of the uncertainties are assumed. Another approach to modeling uncertainty is referred to as unknown but bounded. In this approach, the upper and lower bounds on the uncertainties are assumed without probability distributions. Interval mathematics is a tool for the practical use and extension of the unknown but bounded concept. In this study, the calculation of transmission line sag was used as an example to demonstrate the use of interval mathematics. The objective was to determine the change in cable length, based on a fixed span and an interval of cable sag values for a range of temperatures. The resulting change in cable length was an interval corresponding to the interval of cable sag values. It was shown that there is a small change in conductor length due to variation in sag based on the temperature ranges used in this study. 8 refs.

    Full Text Available This paper presents the results of the isotopic studies made on the anthropological remains recovered in the archaeological excavation of the early medieval site of San Martín of Dulantzi (Alegría–Dulantzi, Álava, carried out by the archaeological company Iterbide. The discovery of a series of tombs dating in the 6th and 7th centuries inside a church, some of them containing grave goods, has enabled the analysis, in critical terms, of the status, the eating patterns and the mobility of these individuals through the analysis of the isotopes and the funerary rites. Specifically, it has been possible to observe that it is a local society, with a scarce impact of immigrants, and the personal ornaments constitute a social status marker inside a community with homogeneous lifestyle. Likewise, these results are discussed in the context of other studies conducted at several European sites of the same chronology.En este artículo se presentan los resultados de los estudios isotópicos realizados sobre los restos antropológicos recuperados en la intervención arqueológica de carácter preventivo realizada en el yacimiento altomedieval de San Martín de Dulantzi (Alegría- Dulantzi, Álava por parte de la empresa Iterbide. El hallazgo de una serie de tumbas fechadas en los siglos VI y VII en el interior de una iglesia, algunas de las cuales dotadas de objetos de adorno personal, ha permitido analizar en términos críticos el estatus, los patrones alimentarios y la movilidad de estos individuos a partir del análisis de los isotopos y de los rituales funerarios. Más concretamente se ha podido observar que se trata de una sociedad local, con una escasa incidencia de inmigrantes, y que los objetos de adorno personal constituyen un marcador de estatus social en el seno de una comunidad que presenta niveles de vida homogéneos.

    The paper is devoted to chosen direct interval methods for solving linear interval systems with special type of matrix. This kind of matrix: band matrix with a parameter, from finite difference problem is obtained. Such linear systems occur while solving one dimensional wave equation (Partial Differential Equations of hyperbolic type) by using the central difference interval method of the second order. Interval methods are constructed so as the errors of method are enclosed in obtained results, therefore presented linear interval systems contain elements that determining the errors of difference method. The chosen direct algorithms have been applied for solving linear systems because they have no errors of method. All calculations were performed in floating-point interval arithmetic.

    Full Text Available This paper shows how to obtain the values of the numerator and denominator Kharitonov polynomials of an interval plant from its value set at a given frequency. Moreover, it is proven that given a value set, all the assigned polynomials of the vertices can be determined if and only if there is a complete edge or a complete arc lying on a quadrant. This algorithm is nonconservative in the sense that if the value-set boundary of an interval plant is exactly known, and particularly its vertices, then the Kharitonov rectangles are exactly those used to obtain these value sets.

  7. Statistics of return intervals between long heartbeat intervals and their usability for online prediction of disorders

    2009-01-01

    We study the statistics of return intervals between large heartbeat intervals (above a certain threshold Q) in 24 h records obtained from healthy subjects. We find that both the linear and the nonlinear long-term memory inherent in the heartbeat intervals lead to power-laws in the probability density function P Q (r) of the return intervals. As a consequence, the probability W Q (t; Δt) that at least one large heartbeat interval will occur within the next Δt heartbeat intervals, with an increasing elapsed number of intervals t after the last large heartbeat interval, follows a power-law. Based on these results, we suggest a method of obtaining a priori information about the occurrence of the next large heartbeat interval, and thus to predict it. We show explicitly that the proposed method, which exploits long-term memory, is superior to the conventional precursory pattern recognition technique, which focuses solely on short-term memory. We believe that our results can be straightforwardly extended to obtain more reliable predictions in other physiological signals like blood pressure, as well as in other complex records exhibiting multifractal behaviour, e.g. turbulent flow, precipitation, river flows and network traffic.

The results were expressed as relative percentage of frequency (Fr% and as percentage of mean bulk (Vm%. Mammals, mainly rodents, were the staple in the diet (annual Vm% = 62.9 and reached a maximum peak in winter (Vm% = 79.4. Vegetables were mostly represented by Rosaceae fruits (annual Vm% = 22.3 and were consumed during all year round. Insects, mainly Coleoptera and Orthoptera, were fairly frequently eaten, although their volume was not remarkable (annual Vm% = 4.1. Birds and garbage were scarcely used. The trophic niche breadth of the stone marten, evaluated using the Levin's index (B, varied from 2.49 in winter to 4.8 in summer.

    The use of natural fiber reinforcement thermoplastic polymer is continuously increasing. This fact is manly due to its advantages as low cost, availability, recyclability, low energy demand and then environmental appeal if compared to synthetics fibers. The composites were prepared in different fiber volume ratios (5%, 10% and 20%) mixed with high density polyethylene (HDPE) and heated at 190 deg C. Thermogravimetric analysis and differential scanning calorimetry were used to investigate thermal stability. The composites structure was characterized by Fourier Transform Infrared spectroscopy, X-ray diffractometry. Fiber and residue of piassava (Attalea funifera Mart) chemical composition were determined by Van Soest Method. The results indicate that thermo stability of the composites of HDPE prepared with fiber volume ratios up to 20% is only slightly lowered. (author)

    Full Text Available The American marten (Martes americana was reintroduced to both the Upper (UP and northern Lower Peninsula (NLP of Michigan during the 20th century. This is the first report of endoparasites of American marten from the NLP. Faeces from live-trapped American marten were examined for the presence of parasitic ova, and blood samples were obtained for haematocrit evaluation. The most prevalent parasites were Capillaria and Alaria species. Helminth parasites reported in American marten for the first time include Eucoleus boehmi, hookworm, and Hymenolepis and Strongyloides species. This is the first report of shedding of Sarcocystis species sporocysts in an American marten and identification of 2 coccidian parasites, Cystoisospora and Eimeria species. The pathologic and zoonotic potential of each parasite species is discussed, and previous reports of endoparasites of the American marten in North America are reviewed.

    Full Text Available This study aims to provide and analyze Francisco Martínez de la Rosa’s unpublished correspondence during his term as President of the Spanish Government in the 1834-1835 biennium, maintained with Amat di San Filippo Luigi, nuncio in Spain, and kept in the Vatican Secret Archives. Such correspondence consists of three letters with official mail format, although they could be considered rather confidential for their content. In these documents, the Spanish government strives, albeit unsuccessfully, to achieve recognition by Rome of Elizabeth II of Spain and his liberal regime. And last but not least, in this paper, it is also noteworthy to highlight the urgent need to fill the many vacant Dioceses in Spain.

    Full Text Available 1915 is considered a decisive year in world history. Underneath wartime plundering, eighteenth-century beliefs in social progress and human civilization collapsed, and other political and philosophical credos sprouted, while aesthetic avant-gardes created new forms of artistic and literary expression. That same year, from his exile in Madrid, Martín Luis Guzmán would define the coordinates that would guide his life, while trying to assimilate his recent experiences during the Mexican Revolution and make way as a writer, under the immediate protection of Alfonso Reyes and the far-away but determining one of Pedro Henríquez Ureña. Without abandoning his political vocation and remaining open to new trends, Guzmán drew up his own path, which would lead him alongside his mentors and to the forefront of literature in Spanish.

  9. José Martí e los indios de Norteamérica: mediazione culturale e «scontro di civiltà». Una rilettura critica

    Directory of Open Access Journals (Sweden)

    Alessandro Badella

    2010-01-01

    Full Text Available The Cuban poet José Martí, “Master of the Americas” as pointed out by a famous Italian study by Carlo Batà, was probably the most important South American thinker of the two last decades of the Nineteenth century. This essay deals with the importance of “civilization clash” between US positivism - or WASP-ism - and the last resistances of Native Americans' cultural heritage during his personal experience as an exile in the United States. Martí, in this racial struggle and racist instincts, experienced a dual vision about the “Indian problem” in the Americas. In his first essays he focused on the positivistic view, really common among Latin American cultural élites (from Alberdi to Sarmiento, which depicted the Indian people as the burden of creole and white race in the path toward progress.On the other hand, as appeared clearly in Escenas americanas, the Cuban analysed more precisely the American struggle between civilization and savagery. In the cultural massacre inflicted to Indian tribes, he saw the real savagery in American civilization. So, this reflection paved the way to a new approach in considering the possibility of importing the Anglo-saxon model of civilization and political structures to the liberated Cuba after the independence (but also to continental Latin America.This relationship let us understand some interesting features in Martí's huge cultural production. We are introduced to the very essence of his cultural mediation between those two different lifestyles and models of civilization. This mediation would have represented a new way of intending North vs South America struggles or even Western way of life vs different ones, considered “barbarous” from the first.In our modern times, in which the terms “exporting values” or “civilization clash” seem to be very common in usage, it is really stimulating discover that the same problem was posed by Martí more than one century ago. Even if he did not

  10. Interval Mathematics Applied to Critical Point Transitions

    Directory of Open Access Journals (Sweden)

    Benito A. Stradi

    2012-03-01

    Full Text Available The determination of critical points of mixtures is important for both practical and theoretical reasons in the modeling of phase behavior, especially at high pressure. The equations that describe the behavior of complex mixtures near critical points are highly nonlinear and with multiplicity of solutions to the critical point equations. Interval arithmetic can be used to reliably locate all the critical points of a given mixture. The method also verifies the nonexistence of a critical point if a mixture of a given composition does not have one. This study uses an interval Newton/Generalized Bisection algorithm that provides a mathematical and computational guarantee that all mixture critical points are located. The technique is illustrated using several example problems. These problems involve cubic equation of state models; however, the technique is general purpose and can be applied in connection with other nonlinear problems.

    Jonsson, Ari; Frank, Jeremy

    2013-01-01

    In this paper we describe Constraint-based Attribute and Interval Planning (CAIP), a paradigm for representing and reasoning about plans. The paradigm enables the description of planning domains with time, resources, concurrent activities, mutual exclusions among sets of activities, disjunctive preconditions and conditional effects. We provide a theoretical foundation for the paradigm, based on temporal intervals and attributes. We then show how the plans are naturally expressed by networks of constraints, and show that the process of planning maps directly to dynamic constraint reasoning. In addition, we de ne compatibilities, a compact mechanism for describing planning domains. We describe how this framework can incorporate the use of constraint reasoning technology to improve planning. Finally, we describe EUROPA, an implementation of the CAIP framework.

    1987-10-01

    Early diastolic time intervals have been assessed by means of the echopolycardiographic method in 17 pregnant women who developed hypertension during pregnancy (HP) and in 14 normal pregnant women (N). Systolic time intervals (STI), stroke volume (SV), ejection fraction (EF), and mean velocity of myocardial fiber shortening (VCF) were also evaluated. Recordings were performed in the left lateral decubitus (LLD) and then in the supine decubitus (SD). In LLD, isovolumic relaxation period (IRP) was prolonged in the hypertensive pregnant women compared with normal pregnant women (HP 51 +/- 12.5 ms, N 32.4 +/- 15 ms p less than 0.05), whereas time of the mitral valve maximum opening (DE) was not different in the groups. There was no difference in SV, EF, and mean VCF, whereas STI showed only a significant (p less than 0.05) lengthening of pre-ejection period (PEP) in HP. When the subjects shifted from the left lateral to the supine decubitus position, left ventricular ejection time index (LVETi) and SV decreased significantly (p less than 0.05) in both normotensive hypertensive pregnant women. IRP and PEP lengthened significantly (p less than 0.05) only in normals, whereas they were unchanged in HP. DE time did not vary in either group. In conclusion, hypertension superimposed on pregnancy induces lengthening of IRP, as well as of PEP, and minimizes the effects of the postural changes in preload on the above-mentioned time intervals.

    Aims To investigate a possible association of sibutramine with QT interval prolongation. Methods Post-marketing surveillance using prescription event monitoring in the New Zealand Intensive Medicines Monitoring Programme (IMMP) identified a case of QT prolongation and associated cardiac arrest in a patient taking sibutramine for 25 days. This patient was further investigated, including genotyping for long QT syndrome. Other IMMP case reports suggesting arrhythmias associated with sibutramine were assessed and further reports were obtained from the World Health Organisation (WHO) adverse drug reactions database. Results The index case displayed a novel mutation in a cardiac potassium channel subunit gene, KCNQ1, which is likely to prolong cardiac membrane depolarization and increase susceptibility to long QT intervals. Assessment of further IMMP reports identified five additional patients who experienced palpitations associated with syncope or presyncopal symptoms, one of whom had a QTc at the upper limit of normal. Assessment of reports from the WHO database identified three reports of QT prolongation and one fatal case of torsade de pointes in a patient also taking cisapride. Conclusions This case series suggests that sibutramine may be associated with QT prolongation and related dysrhythmias. Further studies are required, but in the meantime we would recommend that sibutramine should be avoided in patients with long QT syndrome and in patients taking other medicines that may prolong the QT interval.

    Full Text Available The approximation of a function f∈C[a,b] by Bernstein polynomials is well-known. It is based on the binomial distribution. O. Szasz has shown that there are analogous approximations on the interval [0,∞ based on the Poisson distribution. Recently R. Mohapatra has generalized Szasz' result to the case in which the approximating function is αe−ux∑k=N∞(uxkα+β−1Γ(kα+βf(kαuThe present note shows that these results are special cases of a Tauberian theorem for certain infinite series having positive coefficients.

Para Martí, la educación debía estar encaminada a la liberación, pero basándose en el conocimiento y en la revalorización de la cultura y los valores latinoamericanos, y en manera alguna podía ser privilegio exclusivo de una clase.   José Martí gave to education a fundamental role as an element of socio-political and economic transformation, in which Socratic methods were reinvented to overcome conservative methodologies which were embedded in the most reactionary intellectuals. Therefore, this paper looks at his perspective over education.

    On November 16, 1989 the world was shocked by the news of the assassination of six Jesuits at the campus of the Universidad Centro Americana José Simeón Cañas (UCA) in San Salvador, El Salvador. Among those murdered by government soldiers was Ignacio Martín-Baró, a PhD in social psychology from the University of Chicago who at that time was the Vice-Rector for Academic Affairs and Vice-President of the Interamerican Society of Psychology (SIP). Drawing on Martín-Baró's published writings and non-published academic papers and correspondence, this article traces the evolution of the Spanish-born Jesuit who became a leading authority among Latin American social psychologists. In particular, it analyzes his project of becoming a clinical psychologist under the influence of psychoanalysis, his critical social psychology aimed to "de-ideologize" the oppressed social classes of El Salvador, and his ultimate project of a psychology of liberation for Latin America. Martín-Baró's work came to a tragic end just when it began to bear fruit, but it stands as a testimony to a lifetime committed to the human values of democracy, social justice and service to society's poorest and most neglected.

    Histologic and molecular heterogeneity is well recognized in malignant melanoma; however, the diversity of expression of new and classic melanoma markers has not been correlated in serial sections of metastases. We examined and correlated the expression of microphthalmia transcription factor (MITF) with its transcriptional targets, including melastatin (MLSN1/TRPM1), pigment epithelium-derived factor (SERPINF1/PEDF), SILV/PMEL17/GP100 (human melanoma black 45 [HMB-45]), and melanoma antigen recognized by T cells 1 (MART-1)/MLANA, in 13 melanoma metastases in lymph nodes of 13 patients. The expression levels and patterns of marker expression were recorded by a semiquantitative, 4-point ordinal reactivity method. Our results showed a consistently robust and diffuse expression of MITF protein in 12 (92%) of 13 metastatic tumors compared with variable expression of MLSN1 (46%) messenger RNA or PEDF (75%), HMB-45 (54%), and MART-1 (46%) proteins. Overall, in melanoma lymph node metastases, MITF protein expression was not tightly correlated with its gene targets. Moreover, the immunoreactivity for MITF, compared with MART-1 and HMB-45, was retained, supporting immunohistochemical detection of MITF as a more sensitive method of detecting metastatic melanoma. © American Society for Clinical Pathology, 2016.

    Full Text Available Bolívar, San Martin and Páez are the only Independence protagonists to whom Martí devotes his celebratory speeches and chronicles. Those texts were published throughout a decade [from 1883 to 1894], exactly when Latin American political and cultural leaders regard themselves as having the right to establish [not without dispute] those "places of memory" [in the sense of Nora 2003] which monumentalize a recent heroic history. The texts by Martí are interesting in this sense: facing the imminent fight for the independence of Cuba, his evocation of past heroic deeds acquires a special symbolic value. It assumes the return to a finished era but from which ethical, social and political key values for the present must be extracted. Martí encourages the cult of the heroes but, at the same time, he imposes specific and divergent meanings. He celebrates the heroic deed but also emphasizes the bond between the leaders and the people, by pointing out the authority of both of them in materializing independency and the exclusion of the latter from the processes of modernization. And also, in his assessment, he warns about the errors of the leaders linked to the 'blindness of power'

  15. Confidence intervals for the lognormal probability distribution

    Smith, D.L.; Naberejnev, D.G.

    2004-01-01

    The present communication addresses the topic of symmetric confidence intervals for the lognormal probability distribution. This distribution is frequently utilized to characterize inherently positive, continuous random variables that are selected to represent many physical quantities in applied nuclear science and technology. The basic formalism is outlined herein and a conjured numerical example is provided for illustration. It is demonstrated that when the uncertainty reflected in a lognormal probability distribution is large, the use of a confidence interval provides much more useful information about the variable used to represent a particular physical quantity than can be had by adhering to the notion that the mean value and standard deviation of the distribution ought to be interpreted as best value and corresponding error, respectively. Furthermore, it is shown that if the uncertainty is very large a disturbing anomaly can arise when one insists on interpreting the mean value and standard deviation as the best value and corresponding error, respectively. Reliance on using the mode and median as alternative parameters to represent the best available knowledge of a variable with large uncertainties is also shown to entail limitations. Finally, a realistic physical example involving the decay of radioactivity over a time period that spans many half-lives is presented and analyzed to further illustrate the concepts discussed in this communication

  17. Serial binary interval ratios improve rhythm reproduction.

    2013-01-01

    Musical rhythm perception is a natural human ability that involves complex cognitive processes. Rhythm refers to the organization of events in time, and musical rhythms have an underlying hierarchical metrical structure. The metrical structure induces the feeling of a beat and the extent to which a rhythm induces the feeling of a beat is referred to as its metrical strength. Binary ratios are the most frequent interval ratio in musical rhythms. Rhythms with hierarchical binary ratios are better discriminated and reproduced than rhythms with hierarchical non-binary ratios. However, it remains unclear whether a superiority of serial binary over non-binary ratios in rhythm perception and reproduction exists. In addition, how different types of serial ratios influence the metrical strength of rhythms remains to be elucidated. The present study investigated serial binary vs. non-binary ratios in a reproduction task. Rhythms formed with exclusively binary (1:2:4:8), non-binary integer (1:3:5:6), and non-integer (1:2.3:5.3:6.4) ratios were examined within a constant meter. The results showed that the 1:2:4:8 rhythm type was more accurately reproduced than the 1:3:5:6 and 1:2.3:5.3:6.4 rhythm types, and the 1:2.3:5.3:6.4 rhythm type was more accurately reproduced than the 1:3:5:6 rhythm type. Further analyses showed that reproduction performance was better predicted by the distribution pattern of event occurrences within an inter-beat interval, than by the coincidence of events with beats, or the magnitude and complexity of interval ratios. Whereas rhythm theories and empirical data emphasize the role of the coincidence of events with beats in determining metrical strength and predicting rhythm performance, the present results suggest that rhythm processing may be better understood when the distribution pattern of event occurrences is taken into account. These results provide new insights into the mechanisms underlining musical rhythm perception.

    Full Text Available This article discusses the autobiographical accounts of three Republican women from the first generation of Republican exiles, born between 1900 and 1910. The stories are those of Constancia de la Mora, Silvia Mistral and Dolores Martí, all written just following the Spanish Civil War, between 1939 and 1940, although for two of the authors this was the first stage of exile that finally took them on to Mexico. These accounts are examined within the framework of the socio-political context in which the authors lived during the first three decades of the twentieth century. The stories mix the personal and individual with the collective memory. The women harbour very contrary political views - communist and anarchist - within the Republican cause but the fact that they are women with a common plight helps to overcome these differences. The political nature of these narratives also provides a common theme, which forms a collective testimony in the Republican exile period.

Aparece en ellos el fruto de una memoria personal e individual, pero insertada en la memoria colectiva de su grupo de referencia, el colectivo exiliado. Las autoras representan tendencias políticas opuestas dentro del bando republicano: el comunismo y el anarquismo, aunque su condición femenina y las circunstancias comunes que atraviesan matizan esas diferencias en sus relatos.

    A new directed interval-based tomographic reconstruction algorithm, called non-additive interval based expectation maximization (NIBEM) is presented. It uses non-additive modeling of the forward operator that provides intervals instead of single-valued projections. The detailed approach is an extension of the maximum likelihood—expectation maximization algorithm based on intervals. The main motivation for this extension is that the resulting intervals have appealing properties for estimating the statistical uncertainty associated with the reconstructed activity values. After reviewing previously published theoretical concepts related to interval-based projectors, this paper describes the NIBEM algorithm and gives examples that highlight the properties and advantages of this interval valued reconstruction.

    Staging of melanoma includes quantification of a proliferation index, i.e., presumed melanocytic mitoses of H&E stains are counted manually in hot spots. Yet, its reproducibility and prognostic impact increases by immunohistochemical dual staining for phosphohistone H3 (PHH3) and MART1, which also may enable fully automated quantification by image analysis. To ensure manageable workloads and repeatable measurements in modern pathology, the study aimed to present an automated quantification of proliferation with automated hot-spot selection in PHH3/MART1-stained melanomas. Formalin-fixed, paraffin-embedded tissue from 153 consecutive stage I/II melanoma patients was immunohistochemically dual-stained for PHH3 and MART1. Whole slide images were captured, and the number of PHH3/MART1-positive cells was manually and automatically counted in the global tumor area and in a manually and automatically selected hot spot, i.e., a fixed 1-mm(2) square. Bland-Altman plots and hypothesis tests compared manual and automated procedures, and the Cox proportional hazards model established their prognostic impact. The mean difference between manual and automated global counts was 2.9 cells/mm(2) (P = 0.0071) and 0.23 cells per hot spot (P = 0.96) for automated counts in manually and automatically selected hot spots. In 77 % of cases, manual and automated hot spots overlapped. Fully manual hot-spot counts yielded the highest prognostic performance with an adjusted hazard ratio of 5.5 (95 % CI, 1.3-24, P = 0.024) as opposed to 1.3 (95 % CI, 0.61-2.9, P = 0.47) for automated counts with automated hot spots. The automated index and automated hot-spot selection were highly correlated to their manual counterpart, but altogether their prognostic impact was noticeably reduced. Because correct recognition of only one PHH3/MART1-positive cell seems important, extremely high sensitivity and specificity of the algorithm is required for prognostic purposes. Thus, automated

    Full Text Available A 71-year-old woman collapsed while working as a grocery store cashier. CPR was performed and an AED revealed torsades de pointes (TdP. She was subsequently defibrillated resulting in restoration of sinus rhythm with a QTc interval of 544 msec. Further evaluation revealed a diagnosis of Takotsubo Cardiomyopathy (TCM contributing to the development of a multifactorial acquired long QT syndrome (LQTS. The case highlights the role of TCM as a cause of LQTS in the setting of multiple risk factors including old age, female gender, hypokalemia, and treatment with QT prolonging medications. It also highlights the multifactorial nature of acquired LQTS and lends support to growing evidence of an association with TCM.

  4. Tracking gauge symmetry factorizability on intervals

    We track the gauge symmetry breaking pattern by boundary conditions on fifth and higher-dimensional intervals. It is found that, with Dirichlet-Neumann boundary conditions, the Kaluza-Klein decomposition in five-dimension for arbitrary gauge group can always be factorized into that for separate subsets of at most two gauge symmetries, and so is completely solvable. Accordingly, we present a simple and systematic geometric method to unambiguously identify the gauge breaking/mixing content by general set of Dirichlet-Neumann boundary conditions. We then formulate a limit theorem on gauge symmetry factorizability to recapitulate this interesting feature. Albeit the breaking/mixing, a particularly simple check of orthogonality and normalization of fields' modes in effective 4-dim picture is explicitly obtained. An interesting chained-mixing of gauge symmetries in higher dimensions by Dirichlet-Neumann boundary conditions is also explicitly constructed. This study has direct applications to higgsless/GUT model building

  5. Intervals between multiple fractions per day

    Fowler, J.F.

    Assuming the linear quadratic model for dose-response curves enables the proportion of repairable damage to be calculated for any size of dose per fraction. It is given by the beta (dose squared) term, and represents a larger proportion of the total damage for larger doses per fraction, but also for late-reacting than for early-reacting tissues. For example at 2 Gy per fraction, repairable damage could represent nearly half the total damage in late-reacting tissues but only one fifth in early-reacting tissues. Even if repair occurs at the same rate in both tissues, it will obviously take longer for 50% of the damage to fade to an undetectable level (3 or 5%) than for 20% to do so. This means that late reactions require longer intervals than early reactions when multiple fraction per day radiotherapy is planned, even if the half-lives of repair are not different. (orig.)

    Full Text Available In 1830, the philologist Pedro Martínez López was forced to go into exile in France for political reasons. In 1832, he published Representación a Fernando VII, rey de España, a lampoon in which he made a whole string of accusations against the tyrant. At the end of the following year, he published España en 1833, al expirar Fernando VII, another lampoon in which he blamed the king's despotic reign for the country's disastrous situation and asserted that such abuses and injustices could only be remedied by re-establishing the Constitution of Cádiz of 1812. In 1834, he ceased to rail against his political enemies, changed strategy, and using his considerable imagination, wrote a kind of fable entitled Una noche en el infierno, vista entre sueños. With a mixture of humour and acid wit, it told of how all the devils in the Kingdom of Darkness, embracing the «sacred» cause of liberalism, vented their anger on the deceased Ferdinand and his followers, who were still in power. It would appear that the work was a success, since it was republished in 1836. In 1835, disillusioned with the tepid and conservative liberal regime of the Estatuto Real, Martínez López wrote another story, Las Brujas en Zugarramurdi, in which different satanic creatures, this time sorceresses, take it upon themselves to defeat moderantismo and establish a progressive regime. After this, he ceased to publish lampoons and political parables and devoted himself to producing learned works, bringing out various dictionaries and grammars which were republished several times. | En 1830, el filólogo Pedro Martínez López tuvo que exiliarse a Francia por motivos políticos.

    Full Text Available Nowadays, environmental impact, safety and fuel efficiency are fundamental issues for the automotive industry. These objectives are met by using a combination of different types of steels in the auto bodies. Therefore, it is important to have an understanding of how dissimilar materials behave when they are welded. This paper presents the process parameters’ optimization procedure of fiber laser welded dissimilar high strength low alloy (HSLA and martensitic steel (MART steel using a Taguchi approach. The influence of laser power, welding speed and focal position on the mechanical and microstructural properties of the joints was determined. The optimum parameters for the maximum tensile load-minimum heat input were predicted, and the individual significance of parameters on the response was evaluated by ANOVA results. The optimum levels of the process parameters were defined. Furthermore, microstructural examination and microhardness measurements of the selected welds were conducted. The samples of the dissimilar joints showed a remarkable microstructural change from nearly fully martensitic in the weld bead to the unchanged microstructure in the base metals. The heat affected zone (HAZ region of joints was divided into five subzones. The fusion zone resulted in an important hardness increase, but the formation of a soft zone in the HAZ region.

    Full Text Available Although the use of medicinal plants or natural products has increased in recent decades all over the world, little information is available on their potential risk to health. Annona crassiflora Mart., a plant commonly known as araticum in Brazil, has been widely used in folk medicine for a long time since its seeds and leaves are often utilised in the treatment of cancer, snake bites, and venereal diseases, its fruits are consumed as tonic and astringent, and its bark powder has anti-fungal and anti-rheumatic properties. To evaluate the genotoxic and mutagenic properties induced by the ethanolic extract of araticum leaves, we performed the prophage λ induction (Inductest and bacterial mutagenicity assays. We used Escherichia coli WP2s(λ and RJF013 strains in the lysogenic induction test, whereas the mutagenic studies were carried out using Salmonella typhimurium histidine auxotroph strains TA97a, TA98, TA100, and TA102. Each experiment was performed three times in duplicate and included positive and negative controls. No statistically significant (p > 0.05 positive results were obtained for any of the strains tested, which suggests that the ethanolic extract of araticum leaves did not exhibit direct mechanisms of genotoxicity or mutagenicity that could be detected by the tests used in the present work.

    In this work a thermochemical equilibrium model for downdraft gasifiers has been proposed. The model was compared to the model developed in Gordon and McBride (1994). The properties such as efficiency of cold gas, LHV and temperature of an Amazonian biomass Euterpe olearacea Mart. was simulated. The numerical simulations aimed the maximization of H{sub 2} and CH{sub 4} in a gasification process. The model simulated numerically the influence of the gasifying relative fuel/air ratio and the biomass moisture content on the syngas composition. Two values of moisture content 33% and 37.5% were suggested for the gasification of acai seed for the maximization of the H{sub 2} and CH{sub 4} concentrations in a range of the equivalence ratio, {phi}, between 2.3 and 4. The results also showed that to achieve the maximization of CH{sub 4} with {phi} = 4 the reaction temperature drops in average of 35.44%. (author)

    Full Text Available Species distribution models (SDMs help identify areas for the development of populations or communities to prevent extinctions, especially in the face of the global environmental change. This study modeled the potential distribution of the tree Picea chihuahuana Martínez, a species in danger of extinction, using the maximum entropy modeling method (MaxEnt at three scales: local, state and national. We used a total of 38 presence data from the Sierra Madre Occidental. At the local scale, we compared MaxEnt with the reclassification and overlay method integrated in a geographic information system. MaxEnt generated maps with a high predictive capability (AUC > 0.97. The distribution of P. chihuahuana is defined by vegetation type and minimum temperature at national and state scales. At the local scale, both models calculated similar areas for the potential distribution of the species; the variables that better defined the species distribution were vegetation type, aspect and distance to water flows. Populations of P. chihuahuana have always been small, but our results show potential habitat greater than the area of the actual distribution. These results provide an insight into the availability of areas suitable for the species’ regeneration, possibly through assisted colonization.

Estos son algunos de los interrogantes que pretende exponer la inherente tirantez constituyente de todo pensamiento político en relación con la sustancia y el papel de la religión, y su consecuente influencia en el tenor, densidad y caracterización de la política y lo político. Lejos de constituirse en una relación simple o lineal para el pensamiento político, plantea diversas problemáticas que deben ser explicitadas y analizadas.

    2003-01-01

    We report a detailed analysis of the population genetic structure, mating system, and gene flow of heart of palm (Euterpe edulis Mart.-Arecaceae) in central Brazil. This palm is considered a keystone species because it supplies fruits for birds and rodents all year and is intensively harvested for culinary purposes. Two populations of this palm tree were examined, using 18 microsatellite loci. The species displays a predominantly outcrossed mating system (tm = 0.94), with a probability of full sibship greater than 70% within open-pollinated families. The following estimates of interpopulation genetic variation were calculated and found significant: FIT = 0.17, FIS = 0.12, FST = 0.06, and RST = 0.07. This low but significant level of interpopulation genetic variation indicates high levels of gene flow. Two adult trees were identified as likely seed parents (P > 99.9%) of juveniles located at a distance of 22 km. Gene flow over such distances has not been reported before for tropical tree species. The establishment and management of in situ genetic reserves or ex situ conservation and breeding populations for E. edulis should contemplate the collection of several hundreds open-pollinated maternal families from relatively few distant populations to maximize the genetic sampling of a larger number of pollen parents.

  19. Delay-Dependent Guaranteed Cost Control of an Interval System with Interval Time-Varying Delay

    2009-01-01

    Full Text Available This paper concerns the problem of the delay-dependent robust stability and guaranteed cost control for an interval system with time-varying delay. The interval system with matrix factorization is provided and leads to less conservative conclusions than solving a square root. The time-varying delay is assumed to belong to an interval and the derivative of the interval time-varying delay is not a restriction, which allows a fast time-varying delay; also its applicability is broad. Based on the Lyapunov-Ktasovskii approach, a delay-dependent criterion for the existence of a state feedback controller, which guarantees the closed-loop system stability, the upper bound of cost function, and disturbance attenuation lever for all admissible uncertainties as well as out perturbation, is proposed in terms of linear matrix inequalities (LMIs. The criterion is derived by free weighting matrices that can reduce the conservatism. The effectiveness has been verified in a number example and the compute results are presented to validate the proposed design method.

    2014-01-01

    This book presents an innovative new approach to interval analysis. Modal Interval Analysis (MIA) is an attempt to go beyond the limitations of classic intervals in terms of their structural, algebraic and logical features. The starting point of MIA is quite simple: It consists in defining a modal interval that attaches a quantifier to a classical interval and in introducing the basic relation of inclusion between modal intervals by means of the inclusion of the sets of predicates they accept. This modal approach introduces interval extensions of the real continuous functions, identifies equivalences between logical formulas and interval inclusions, and provides the semantic theorems that justify these equivalences, along with guidelines for arriving at these inclusions. Applications of these equivalences in different areas illustrate the obtained results. The book also presents a new interval object: marks, which aspire to be a new form of numerical treatment of errors in measurements and computations.

    The heart integrates neuroregulatory messages into specific bands of frequency, such that the overall amplitude spectrum of the cardiac output reflects the variations of the autonomic nervous system. This modulatory mechanism seems to be well adjusted to the unpredictability of the cardiac demand, maintaining a proper cardiac regulation. A longstanding theory holds that biological organisms facing an ever-changing environment are likely to evolve adaptive mechanisms to extract essential features in order to adjust their behavior. The key question, however, has been to understand how the neural circuitry self-organizes these feature detectors to select behaviorally relevant information. Previous studies in computational perception suggest that a neural population enhances information that is important for survival by minimizing the statistical redundancy of the stimuli. Herein we investigate whether the cardiac system makes use of a redundancy reduction strategy to regulate the cardiac rhythm. Based on a network of neural filters optimized to code heartbeat intervals, we learn a population code that maximizes the information across the neural ensemble. The emerging population code displays filter tuning proprieties whose characteristics explain diverse aspects of the autonomic cardiac regulation, such as the compromise between fast and slow cardiac responses. We show that the filters yield responses that are quantitatively similar to observed heart rate responses during direct sympathetic or parasympathetic nerve stimulation. Our findings suggest that the heart decodes autonomic stimuli according to information theory principles analogous to how perceptual cues are encoded by sensory systems.

  2. An Investigation of Interval Management Displays

    NASA's first Air Traffic Management (ATM) Technology Demonstration (ATD-1) was created to transition the most mature ATM technologies from the laboratory to the National Airspace System. One selected technology is Interval Management (IM), which uses onboard aircraft automation to compute speeds that help the flight crew achieve and maintain precise spacing behind a preceding aircraft. Since ATD-1 focuses on a near-term environment, the ATD-1 flight demonstration prototype requires radio voice communication to issue an IM clearance. Retrofit IM displays will enable pilots to both enter information into the IM avionics and monitor IM operation. These displays could consist of an interface to enter data from an IM clearance and also an auxiliary display that presents critical information in the primary field-of-view. A human-in-the-loop experiment was conducted to examine usability and acceptability of retrofit IM displays, which flight crews found acceptable. Results also indicate the need for salient alerting when new speeds are generated and the desire to have a primary field of view display available that can display text and graphic trend indicators.

    Data regarding hematologic reference intervals (RI) for neonatal calves have not been published yet. The aims of this study were: a) to establish hematology RIs for neonatal Holstein calves, b) to compare them with the RIs for lactating cows, and c) to investigate the relationship of age and gender with the hematologic profile of calves. Two-hundred and fifty-four clinically healthy Holstein calves (1-9days old, from 30 farms) and 82 healthy Holstein cows (between 30 and 150days in milk, from 10 farms) were blood sampled once for a complete blood count evaluation, using the ADVIA 120 hematology analyzer. An additional blood sample was collected from each calf for serum total protein concentration measurement. RIs and age-related RIs were calculated with the Reference Value Advisor freeware. Comparisons between calves and cows and between male and female calves were performed with t-test or Mann-Whitney test. Red blood cell count (RBC), white blood cell count (WBC), neutrophil, lymphocyte and platelet counts in calves were higher, while mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH) and mean corpuscular hemoglobin concentration (MCHC) were lower than in cows. Lymphocyte and platelets showed a notable increase through age. Finally, female calves had higher RBC, hematocrit and hemoglobin concentration than males. Age-specific RIs should be used for the interpretation of the complete blood count in Holstein calves. Copyright © 2018 Elsevier Ltd. All rights reserved.

  5. Restricted Interval Guelph permeameter: Theory and application

    Freifeld, Barry M.; Oldenburg, Curtis M.

    2003-01-01

    A constant head permeameter system has been developed for use in small diameter boreholes with any orientation. It is based upon the original Guelph permeameter concept of using a Mariotte siphon reservoir to control the applied head. The new tool, called a Restricted Interval Guelph (RIG) permeameter uses either a single pneumatic packer or straddle packer to restrict the area through which water is allowed to flow so that the borehole wetted area is independent of the applied head. The RIG permeameter has been used at Yucca Mountain, Nevada, in the nonwelded rhyolitic Paintbrush Tuff. Analysis of the acquired data is based upon saturated-unsaturated flow theory that relies upon the quasi-linear approximation to estimate field-saturated hydraulic conductivity (Kfs) and the a parameter (sorptive number) of the exponential relative hydraulic conductivity pressure head relationship. These results are compared with a numerical model based upon the solution of the Richards equation using a van Genuchten capillary pressure-saturation formulation. The numerical model incorporates laboratory capillary pressure versus saturation functions measured from cores taken from nearby boreholes. Comparison between the analytical and numerical approaches shows that the simple analytic model is valid for analyzing the data collected. Sensitivity analysis performed with the numerical model shows that the RIG permeameter is an effective tool for estimating permeability and sorptive number for the nonwelded Paintbrush Tuff

    There are two natural and well-studied approaches to temporal ontology and reasoning: point-based and interval-based. Usually, interval-based temporal reasoning deals with points as particular, duration-less intervals. Here we develop explicitly two-sorted point-interval temporal logical framework...... whereby time instants (points) and time periods (intervals) are considered on a par, and the perspective can shift between them within the formal discourse. We focus on fragments involving only modal operators that correspond to the inter-sort relations between points and intervals. We analyze...

    Full Text Available Presenting confidence intervals around means is a common method of expressing uncertainty in data. Loftus and Masson (1994 describe confidence intervals for means in within-subjects designs. These confidence intervals are based on the ANOVA mean squared error. Cousineau (2005 presents an alternative to the Loftus and Masson method, but his method produces confidence intervals that are smaller than those of Loftus and Masson. I show why this is the case and offer a simple correction that makes the expected size of Cousineau confidence intervals the same as that of Loftus and Masson confidence intervals.

    High-intensity interval training (HIIT) is a time-efficient strategy shown to induce various cardiovascular and metabolic adaptations. Little is known about the optimal tolerable combination of intensity and volume necessary for adaptations, especially in clinical populations. In a randomized controlled pilot design, we evaluated the effects of two types of interval training protocols, varying in intensity and interval duration, on clinical outcomes in overweight/obese men. Twenty-five men [body mass index (BMI) > 25 kg · m(2)] completed baseline body composition measures: fat mass (FM), lean mass (LM) and percent body fat (%BF) and fasting blood glucose, lipids and insulin (IN). A graded exercise cycling test was completed for peak oxygen consumption (VO2peak) and power output (PO). Participants were randomly assigned to high-intensity short interval (1MIN-HIIT), high-intensity interval (2MIN-HIIT) or control groups. 1MIN-HIIT and 2MIN-HIIT completed 3 weeks of cycling interval training, 3 days/week, consisting of either 10 × 1 min bouts at 90% PO with 1 min rests (1MIN-HIIT) or 5 × 2 min bouts with 1 min rests at undulating intensities (80%-100%) (2MIN-HIIT). There were no significant training effects on FM (Δ1.06 ± 1.25 kg) or %BF (Δ1.13% ± 1.88%), compared to CON. Increases in LM were not significant but increased by 1.7 kg and 2.1 kg for 1MIN and 2MIN-HIIT groups, respectively. Increases in VO2peak were also not significant for 1MIN (3.4 ml·kg(-1) · min(-1)) or 2MIN groups (2.7 ml · kg(-1) · min(-1)). IN sensitivity (HOMA-IR) improved for both training groups (Δ-2.78 ± 3.48 units; p < 0.05) compared to CON. HIIT may be an effective short-term strategy to improve cardiorespiratory fitness and IN sensitivity in overweight males.

Neste trabalho foram estudadas a distribuição, ontogênese, estrutura e ultra-estrutura dos nectários extraflorais (NEFs. Amostras de folhas em várias fases de desenvolvimento foram coletadas, fixadas e processadas para estudos em microscopia de luz e eletrônica de transmissão e varredura, segundo técnicas convencionais. Testes histoquímicos foram empregados para determinar a natureza química da secreção. Os NEFs estão distribuídos por todo o limbo, sendo mais concentrados nos terços basal e médio de cada folíolo. Estes nectários são embutidos no mesofilo, apresentam tecido secretor envolvido por uma endoderme e são vascularizados por xilema e floema. A atividade secretora dos NEFs é limitada à fase juvenil da folha. Nas folhas mais velhas, os NEFs tornam-se não funcionais. O tecido secretor dos NEFs é formado a partir da protoderme, enquanto a endoderme tem origem no meristema fundamental. No tecido secretor de nectários funcionais as células apresentam citoplasma denso, núcleo volumoso, mitocôndrias, plastídios com sistema de membranas pouco desenvolvido, gotas de óleo dispersas no citosol, dictiossomos e segmentos de retículo endoplasmático liso.

    Full Text Available Annona crassiflora Mart known as 'araticum', 'marolo' or 'field araticum' is a typical fruit from the Cerrado biome of Brazil with socio-economic and medicinal importance. Normally, Annona crassiflora is propagated through seeds. However, due to a deep dormancy that the seeds display at dispersion and the difficulty to obtain uniform plants in a short time period, micropropagation may be a feasible alternative. Concentrations of gibberellic acid (GA3 and naphthalene-acetic acid (NAA and their interactive effects on in vitro seed germination and seedling development of Annona crassiflora were studied. Mature fruits of Annona crassiflora were depulped and the seeds washed in clear water and dried at room temperature. Seed coat was removed and the seeds were placed on Murashige & Skoog (MS medium supplemented with gibberellic acid (GA3 and naphthalene-acetic acid (NAA, 30 g L-1 sucrose and 6 g L-1 agar-agar. Seeds were kept under these conditions for 30 days. After this period, seedlings were kept for another 90 days on Wood Plant Medium (WPM with 20 g L-1 sucrose and 5 g L-1 agar-agar supplemented with the same GA3 and NAA concentrations. Cultures were incubated under controlled conditions at 25 ± 2°C temperature, 16: 8 (light: dark photoperiod of 32 µmol m-2 s-1 irradiance provided by cool white fluorescent tubes (Philips. Use of WPM medium supplemented with 25-32 mg L-1 GA3 or MS with 26-30 mg L-1 GA3 and 2 mg L-1 NAA promoted rooting and plant growth.O araticum ou marolo (Annona crassiflora Mart. é uma fruta típica de Cerrado com grande importância sócio-econômico e medicinal.

    The tucuma (Astrocaryum vulgare Mart.) is a native fruit of Amazonia, occurring mainly in the state of Para, but also found in the Brazilian northeast states and in the Brazilian central-western states. The tucuma is considered an excellent source of carotenoids with a very high concentration of {beta}-carotene, which is a precursor of vitamin A. In addition to carotenoids it is an important source of vitamin B2 (riboflavin) in fruits. This study aimed to analyze the effects of gamma radiation on the nutritional value of tucuma. The fruits were irradiated at doses of 0.5, 1.0 and 2.0 kGy irradiator with a source of cesium 137. The carotenoids were determined by spectrophotometry. The analysis of {alpha} and {beta}-carotene, thiamine, riboflavin were carried out by high performance liquid chromatography (HPLC). The {beta}-carotene accounts for 80% of total carotenoids in tucuma, and with a dose of 2 kGy, it showed the highest reduction of {beta}-carotene, about 7.5% in relation to the control. The tucuma fruit showed high levels of riboflavin from 0.183 to 0.222 {mu}g 100 g{sup -1}, and maintained stability after the gamma radiation process. However, it had low levels of thiamine from 0.050 to 0.033 {mu}g 100 g{sup -1}, and irradiated at a dose of 2 kGy showed significant reductions of thiamine, about 34% in relation to the control.

    Inhibition in the human motor cortex can be probed by means of paired-pulse transcranial magnetic stimulation (ppTMS) at interstimulus intervals of 2-3 ms (short-interval intracortical inhibition, SICI) or ∼100 ms (long-interval intracortical inhibition, LICI). Conventionally, SICI and LICI are recorded as motor evoked potential (MEP) inhibition in the hand muscle. Pharmacological experiments indicate that they are mediated by GABAA and GABAB receptors, respectively. SICI and LICI of TMS-evoked EEG potentials (TEPs) and their pharmacological properties have not been systematically studied. Here, we sought to examine SICI by ppTMS-evoked compared to single-pulse TMS-evoked TEPs, to investigate its pharmacological manipulation and to compare SICI with our previous results on LICI. PpTMS-EEG was applied to the left motor cortex in 16 healthy subjects in a randomized, double-blind placebo-controlled crossover design, testing the effects of a single oral dose 20 mg of diazepam, a positive modulator at the GABAA receptor, vs. 50 mg of the GABAB receptor agonist baclofen on SICI of TEPs. We found significant SICI of the N100 and P180 TEPs prior to drug intake. Diazepam reduced SICI of the N100 TEP, while baclofen enhanced it. Compared to our previous ppTMS-EEG results on LICI, the SICI effects on TEPs, including their drug modulation, were largely analogous. Findings suggest a similar interaction of paired-pulse effects on TEPs irrespective of the interstimulus interval. Therefore, SICI and LICI as measured with TEPs cannot be directly derived from SICI and LICI measured with MEPs, but may offer novel insight into paired-pulse responses recorded directly from the brain rather than muscle.

    Full Text Available José Martí proposes that for the proper development of the Republic in America it is essential to secure a government that has as the premises of its administration the natural categories of its origin. To evaluate the local characteristics Martí was thinking of I will carry out an analysis of two of his essays: Nuestra América (Martí, 1977 and Coney Island (Martí, 1881, in an attempt to unravel the polarisation strategy which supports his argument. Indeed, through a semantic axis the author places the concepts of nature and interiority over external and foreign, making a parallel between what he calls “natural men in America” and those who represent the “other”, the people of the United States. In this way, it will be possible to see how Martí will question the alleged hegemony of the northern country, claiming the primitive qualities of American indigenous peoples, to condition the problem of allocation of barbarism. The main theoretical framework to address this work is the use of the theories of discourse analysis of Teun van Dijk, which will serve me to develop and analyse the semantic axis that Martí creates in the works studied.José Martí propone que para el buen desarrollo de la República en América es indispensable un gobierno que fije como premisas para su administración las categorías naturales y autóctonas de su origen.

    Highlights: → We present a new Loading Pattern Optimization method - Interval Bound Algorithm (IBA). → IBA directly uses the reactivity of fuel assemblies and burnable poison. → IBA can optimize fuel assembly orientation in a coupled way. → Numerical experiment shows that IBA outperforms genetic algorithm and engineers. → We devise DDWF technique to deal with multiple objectives and constraints. - Abstract: In order to optimize the core loading pattern in Nuclear Power Plants, the paper presents a new optimization method - Interval Bound Algorithm (IBA). Similar to the typical population based algorithms, e.g. genetic algorithm, IBA maintains a population of solutions and evolves them during the optimization process. IBA acquires the solution by statistical learning and sampling the control variable intervals of the population in each iteration. The control variables are the transforms of the reactivity of fuel assemblies or the worth of burnable poisons, which are the crucial heuristic information for loading pattern optimization problems. IBA can deal with the relationship between the dependent variables by defining the control variables. Based on the IBA algorithm, a parallel Loading Pattern Optimization code, named IBALPO, has been developed. To deal with multiple objectives and constraints, the Dynamic Discontinuous Weight Factors (DDWF) for the fitness function have been used in IBALPO. Finally, the code system has been used to solve a realistic reloading problem and a better pattern has been obtained compared with the ones searched by engineers and genetic algorithm, thus the performance of the code is proved.

    Full Text Available In solving many statistical problems, the most precise choice of the distribution law of a random variable is required, the sample of which the authors observe. This choice requires the construction of an interval series. Therefore, the problem arises of assigning an optimal number of intervals, and this study proposes a number of formulas for solving it. Which of these formulas solves the problem more accurately? In [9], this question is investigated using the Pearson criterion. This article describes the procedure and on its basis gives formulas available in literature and proposed new formulas using the entropy coefficient. A comparison is made with the previously published results of applying Pearson's concord criterion for these purposes. Differences in the estimates of the accuracy of the formulas are found. The proposed new formulas for calculating the number of intervals showed the best results. Calculations have been made to compare the work of the same formulas for the distribution of sample data according to the normal law and the Rayleigh law.

    Full Text Available Este estudo teve como objetivo quantificar o impacto da herbivoria por caprinos sobre as populações naturais de Bromelia laciniosa Mart. ex Schult. f. (Bromeliaceae, espécie endêmica da Caatinga. Os estudos de campo foram desenvolvidos na localidade de Caboclo (8º28'56,4"S, 40º56'6,9"W, 588 m alt., Município de Afrânio, Pernambuco. Essa área é considerada de alta importância biológica e, portanto, prioritária para a conservação. A análise quantitativa desse impacto foi realizada a partir do inventário de 10 parcelas com 2.000 m², ao longo de uma trilha pré-existente na área de estudo, e consistiu em contabilizar os indivíduos de B. laciniosa em floração e o porcentual de indivíduos que tiveram suas inflorescências forrageadas pelos caprinos. Adicionalmente, também foram obtidas informações referentes à fenologia, à morfologia floral e às taxas de formação de frutos e sementes dessa Bromeliaceae. Verificou-se que, dos 246 indivíduos inventariados, 65,8% tiveram suas inflorescências forrageadas por esses animais. A estimativa do número de flores consumidas foi de 8.748 e o número provável de frutos e sementes que deixaram de ser produzidos, de aproximadamente 7.227 e 252.945, respectivamente. O forrageamento das inflorescências diminuiu as taxas de formação de frutos e sementes, podendo, desse modo, interferir diretamente na conservação dessa bromélia.

    Full Text Available The evaluation of the leishmanicidal and trypanocidal activity of the hydroalcoholic extract of the bark of Stryphnodendron rotundifolium Mart. (EHCSR was carried out to find an alternative treatment for parasitic diseases. EHCSR was prepared and used at four different concentrations (1000, 500, 250, 125 μg/mL in in vitro assays for activity against Leishmania promastigotes using the species Leishmania brasiliensis and Leishmania infantum and for trypanocidal activity using the epimastigotes of Trypanosoma cruzi. We also tested EHCSR for cytotoxicity against adhered cultured Murine J774 fibroblasts. The tests were performed in triplicate, and the percent mortality of parasites, IC50 and percent toxicity were determined. With regard to anti-leishmania activity against L. infantum, there was a mean mortality of 45% at all concentrations, and against L. brasiliensis, a substantial effect was seen at 1000 μg/mL with 56.38% mortality, where the IC50 values were 1338.76 and 987.35 μg/mL, respectively. Trypanocidal activity was notably high at 1000 μg/mL extract with 82.31% mortality of epimastigotes. Cytotoxicity at the highest extract concentrations of 500 and 1000 μg/mL was respectively 75.12% and 94.14%, with IC50 = 190.24 μg/mL. Despite that the extract has anti-parasitic activity, its substantial cytotoxicity against fibroblasts cells makes its systemic use nonviable as a therapeutic alternative.

    Full Text Available Fall armyworm, Spodoptera frugiperda J.E. Smith, 1797 (Lepidoptera: Noctuidae is the main pest of maize, besides attacking sorghum and cotton crops. The control of this pest has been accomplished mainly with the use of synthetic insecticides but, due to the growing concern about the environment and food quality, phenolic compounds have shown their potential for the biological control of this insect. Thus, the objective of the present study was to evaluate the efficiency of the extract of jabuticabeira, Myrciaria cauliflora [Mart.] O. Berg (Myrtaceae fruit skin flour in the control of S. frugiperda. Skins of M. cauliflora Sabará genotype were dried at 45 °C in a forced air oven. In order to obtain the extract, 1.0 g flour was mixed with 10 mL acetone: water solution (7:3 v/v. Forty-eight-hour-old S. frugiperda caterpillars were placed in glass tubes with an artificial diet containing the extract at concentrations of 0, 250, 500, 1000, and 2000 mg L-1. The extract, in which the phenolic compounds gallic acid, gallocatechin, catechin, epicatechin, ellagic acid, and salicylic acid were identified at a concentration of 2000 mg L-1, in average, increased mortality rates by 150% in the larval stage, duration of larval stages by 60%, and pupal by 17%, and decreased amount of females by 55%. On the other hand, the extract at 1000 mg L-1 only increased duration of larval period by 24%. It was concluded that the extract is harmful to this insect, probably due to the presence of phenolic compounds.

    Ramírez, Antonieta

    2017-01-01

    La creciente tendencia hacia la desmaterialización de la realidad, de las relaciones y de los mismos sujetos en el mundo que habitamos es motivo suficiente para que Martín De Mauro plantee la pregunta sobre si “¿el cuerpo, o cualquier modalidad material del cuerpo es puro efecto del lenguaje?” (p. 26). Su inquietud tiene como principal motivo la “sospecha generalizada de una pérdida o menosprecio del cuerpo como realidad, naturaleza y materia sexuada” (p. 29), por lo que, para dirimir esta su...

    Full Text Available Intelectuales de la talla de José Martí, quien en los contenidos de sus discursos expone y desglosa, mucho antes que la teoría feminista se desarrollara sólidamente, los problemas de diferenciación, marginación y subvaloración en que la mujer se encontraba inmersa; así como las repercusiones en el desarrollo social e individual que los mismos poseían, son elementos necesarios a destacar en nuestro siglo. Con vista a insertar el pensamiento martiano en los estudios de ésta índole realizados.
