    Full Text Available From 1999 to 2004 the occurence of fungi: Pseudocercosporella herpotrichoides (Fron. and Fusarium spp. was evaluated in small plot field trials on seven varieties of winter wheat. The efficacy of fungicide protection against stem base diseases and influence on yields was monitored in field conditions in Velká Bystřice near Olomouc.For diagnostic of casual fungi two methods were used: 1. Method of coloring mycelium in stems, 2. Method of cultivation of mycelim on agar.Results from detection of casual fungi are following: Pseudocercosporella herpotrichoides (Fron., Fusarium culmorum (W. G. Sm. Sacc. and Fusarium graminearum Schwabe.For high efficacy of protection against roots and stem base disease the following fungicide variants should be applied: Sportak Alpha 1.5 l . ha−1 (BBCH 30/Cerelux Plus 0.7 l . ha−1 (BBCH 51, Sportak HF 1 l . ha−1 (BBCH 30/Cerelux Plus 0.7 l . ha−1, Alert S 1.0 l . ha−1 (BBCH 30/Cerelux Plus 0.7 l . ha−1 (BBCH 51. The application of fungicides positively influenced yields. Yield increased at average by10–20 % after the aplication but the rise in yields was not in total correlation with the efficacy. These results can be possibly used in the system of integral control of winter wheat against stem base disease in wheat.

    Genotypes with recombination events in the Triticum ventricosum introgression on chromosome 7D allowed to fine-map resistance gene Pch1, the main source of eyespot resistance in European winter wheat cultivars. Eyespot (also called Strawbreaker) is a common and serious fungal disease of winter wheat caused by the necrotrophic fungi Oculimacula yallundae and Oculimacula acuformis (former name Pseudocercosporella herpotrichoides). A genome-wide association study (GWAS) for eyespot was performed with 732 microsatellite markers (SSR) and 7761 mapped SNP markers derived from the 90 K iSELECT wheat array using a panel of 168 European winter wheat varieties as well as three spring wheat varieties and phenotypic evaluation of eyespot in field tests in three environments. Best linear unbiased estimations (BLUEs) were calculated across all trials and ranged from 1.20 (most resistant) to 5.73 (most susceptible) with an average value of 4.24 and a heritability of H 2  = 0.91. A total of 108 SSR and 235 SNP marker-trait associations (MTAs) were identified by considering associations with a -log 10 (P value) ≥3.0. Significant MTAs for eyespot-score BLUEs were found on chromosomes 1D, 2A, 2D, 3D, 5A, 5D, 6A, 7A and 7D for the SSR markers and chromosomes 1B, 2A, 2B, 2D, 3B and 7D for the SNP markers. For 18 varieties (10.5%), a highly resistant phenotype was detected that was linked to the presence of the resistance gene Pch1 on chromosome 7D. The identification of genotypes with recombination events in the introgressed genomic segment from Triticum ventricosum harboring the Pch1 resistance gene on chromosome 7DL allowed the fine-mapping of this gene using additional SNP markers and a potential candidate gene Traes_7DL_973A33763 coding for a CC-NBS-LRR class protein was identified.

    Full Text Available The maltose and mineral media for isolation of Gaeumannomyces graminis from roots were assessed. The differences in numbers of obtained isolates were found depending on the medium used and sampling date. Easier identification of pathogen was possible employing maltose medium. The fungi from genus Fusarium occurring on winter wheat leaf sheaths were identified by mycological analysis and PCR, while the fungus Pseudocercosporella herpotrichoides was detected by PCR and ELISA methods. PCR and ELISA methods enabled to detect pathogens also in periods before the disease symptoms on plants occurred.

    Full Text Available Abstract. In the Republic of Macedonia, wheat is a very important crop and it is grown on an area of around 250.000 ha. The most important regions for wheat growing are: Bitola, Kumanovo, Sveti Nikole, Skopje, Probistip, Kocani, Veles and Stip. The most important deseases on wheat are: Tapesia yallundae Wallwork and Spooner with its anamorphic stage Pseudocercosporella herpotrichoides (Fron Deighton causer of the desease „eyespot“ on barley and wheat; Puccinia graminis f. spp. tritici; Puccinia racondita f. spp. tritici; Gaeumannomyces graminis var. tritici; Bipolaris sorokiniana (Sacc. Shoemaker; Blumeria graminis var. tritici and Zymoseptoria tritici (Mycospharella graminicola (Fuckel Schroter. Many new diseases on wheat causing significant economic damage to producers are observed in Macedonia. The main aim of this article is to present the symptoms, morphology and protective measures of Zymoseptoria tritici (Mycospharella graminicola, the most widely spread fungal pathogens on wheat in the Republic of Macedonia. In the period between 2014 and 2016, the pathogen fungi on wheat with the highest intensity were: Zymoseptoria tritici, Tapesia yallundae, Puccinia graminis, Puccinia recondita, Gaeumannomyces graminis, Bipolaris sorokiniana, Blumeria graminis. The intensity of the diseases and the damages – yield losses of wheat, differed from year to year and between regions, depended on the sensitivity of the wheat varieties. The smallest yield loss was identified in wheat producers who treated the wheat with pesticides at least twice for vegetation season.

    Full Text Available A detailed analysis of the architectural items from the excavations undertaken more than 25 years ago at the Roman theatre of Italica provides the basis for an essay of graphical anaparastasis of its architectural orders. The most recognisable of these are from the scaenae frons and its porticus post scaenum. This paper not only provides a brief formal reconstruction of the former and its modules but also provides new fundamental data for describing the process of the theatre's construction.Por medio del análisis pormenorizado de los elementos arquitectónicos recuperados a lo largo de las excavaciones que, desde hace ya más de veinticinco años, se vienen desarrollando en el teatro romano de Itálica, hemos intentado llevar a cabo un ensayo de anaparastasis gráfica de sus órdenes arquitectónicos. Los mejor caracterizados son los de su scaenae frons y su porticus post scaenam. El presente estudio se ocupa del primero de ellos, permitiendo no solamente una reconstrucción puramente formal del mismo y sus módulos, sino también la propuesta de una importante reforma de la escena en época severiana, dato fundamental para la determinación del proceso constructivo del edificio.

    Under the primary utilisation of phytosanitary production factors such as selection of variety, crop rotation and N fertilisation according to plant requirements, the IPM Wheat Model comprises the elements diagnosis (qualitative = type of pathogen, quantitative = disease severity), scientifically grounded treatment thresholds which, as critical values in pathogen development, can be applied to define the optimum time of fungicide application, and pathogen-specific effective fungicides and application amounts. This leads to the location and year-specific optimised control of the pathogen and of the associated yield performance. After several years of development in Bavaria (from 1985 on) and Schleswig-Holstein (1993-1999), the model was tested as part of a project involving the Universities of Bonn and Kiel and the plant protection services of the German states of Lower Saxony, North Rhine-Westphalia and Schleswig-Holstein in a three-year study (1999-2001) in interregional locations (usually nine per state) with the winter wheat variety Ritmo (interregional indicator variety) and a further variety of regional importance in different variations (untreated control, three to four times growth stage-oriented variants for the determination of the absolute damage potential, IPM-variant). In exact records (approx. 12 dates per vegetation period), the disease epidemics were recorded weekly. With the genetically uniform indicator variety Ritmo, the results documented substantially differing year- and location-specific disease and yield patterns. Interregionally, a broad wheat pathogen spectrum (Puccinia striiformis, P. recondita, Septoria tritici, Stagonospora (syn. Septoria) nodorum, Blumeria (syn. Erysiphe) graminis, Pseudocercosporella herpotrichoides, Drechslera tritici-repentis) in differing composition, disease severity and damage effect was demonstrated. The heterogeneity of the infection and damage patterns was increased in the case of the second variety, in

    Full Text Available Wheat cv. Grana grown under field conditions, in the early phase of the first node formation, was sprayed with Ethrel (0.35 ml/m2 and with the fungicides: Sportak 45 EC (0.1 ml/m2 and Bayleton Triple (0.2 g/m2 - separately and in conjunction with Ethrel. It was found that Ethrel reduced the plant's susceptibility to infection by Cercosporella herpotrichoides and by species of the genus Fusarium. The fungicides were more active and also reduced the susceptibility to infection by Erysiphe graminis and Puccinia triticina. The fungistatic effect of Ethrel and Sportak was synergistic only in the case of Cercosporella herpotrichoides. Other interactions between Ethrel and fungicides were not found. Ethrel and fungicides only slightly affected the mycoflora of the root but they completely eliminated the fungi of the genus Mucor from the rhizosphere and reduced the participation of isolates of the genus Alternaria and Cladosporium in the rhizosphere and rhizoplane of wheat. The fungicides were more active than Ethrel. An interaction between Ethrel and fungicides in the reduction of fungi of the genus Fusarium in the rhizosphere was shown.

    Purpose: To enable the use of fron 113 as laundry liquid so that sterilizing effect can also be attained during drying. Constitution: After cleaning various kinds of contaminations deposited to cloths in a laundry drum with fron 113 (trichlorofluoroethane), gases in the drum are recycled by a blower passing through a drying condenser and a heater to evaporize solvents or moisture content remained in the cloths. The evaporated solvent or moistures are condensated to recover when they pass through the condenser cooled by the coolants of a refrigerator. Accordingly, since high temperature drying is enabled and moistures can be dried as well by the use of fron 113, no additional provision of the drier is required and sterilizing effect can also be effected at high temperature drying.

    Pseudocercospora is a large cosmopolitan genus of plant pathogenic fungi that are commonly associated with leaf and fruit spots as well as blights on a wide range of plant hosts. They occur in arid as well as wet environments and in a wide range of climates including cool temperate, sub-tropical and tropical regions. Pseudocercospora is now treated as a genus in its own right, although formerly recognised as either an anamorphic state of Mycosphaerella or having mycosphaerella-like teleomorphs. The aim of this study was to sequence the partial 28S nuclear ribosomal RNA gene of a selected set of isolates to resolve phylogenetic generic limits within the Pseudocercospora complex. From these data, 14 clades are recognised, six of which cluster in Mycosphaerellaceae. Pseudocercospora s. str. represents a distinct clade, sister to Passalora eucalypti, and a clade representing the genera Scolecostigmina, Trochophora and Pallidocercospora gen. nov., taxa formerly accommodated in the Mycosphaerella heimii complex and characterised by smooth, pale brown conidia, as well as the formation of red crystals in agar media. Other clades in Mycosphaerellaceae include Sonderhenia, Microcyclosporella, and Paracercospora. Pseudocercosporella resides in a large clade along with Phloeospora, Miuraea, Cercospora and Septoria. Additional clades represent Dissoconiaceae, Teratosphaeriaceae, Cladosporiaceae, and the genera Xenostigmina, Strelitziana, Cyphellophora and Thedgonia. The genus Phaeomycocentrospora is introduced to accommodate Mycocentrospora cantuariensis, primarily distinguished from Pseudocercospora based on its hyaline hyphae, broad conidiogenous loci and hila. Host specificity was considered for 146 species of Pseudocercospora occurring on 115 host genera from 33 countries. Partial nucleotide sequence data for three gene loci, ITS, EF-1α, and ACT suggest that the majority of these species are host specific.

    In the head of the Oriental hornet, beneath the cuticle, there are plaques of hair cells. These are distributed throughout the upper front part of the head; to wit: in the region of the vertex (i.e., around and behind the ocelli), in the genae around and behind the compound eyes (the ommatidia), and in the region of the forehead or frons. These hair cells are arranged with their thin whip-like part (i.e., cilia) directed outward and morphologically fall into three distinct groups: type (a) thin elongated cilia connected to each other alongside by side-links; type (b) thin elongated cilia of which two or more interconnect at their distal ends via a delicate nerve fiber bearing a knob at its center; and type (c) shorter and thicker cilia that roughly resemble a triangular thorn and are also interconnected by a thin thread, which, however, bears a ball rather then a knob at its center. The knob in the one case and the ball in the other vary in their diameter, but in both instances the interconnecting elements, be they nerve fibers or threads, are seemingly multidirectional. Beneath the frons, in the region of the coronal suture, the hair cells (cilial plaques) are inwardly directed and bear a large trachea at their center. Presumably, the "weighted" cilial cells that are directed toward the exterior of the body aid the hornet in navigation and gravity determination whereas the inwardly directed ciliary cells may possibly serve in acoustic communication. Another element worthy of mention within the hair cells are yellow granules (yg). These yg's originate from the whip-like portion of the ciliary cells that are distributed beneath the frons plate, and also in the yellow stripes of the gastral cuticle.

    Organic and inorganic fractions of sediment collected from the bottom of Walker Lake, Nevada, have been dated by carbon-14 techniques. Sedimentation rates and the organic-carbon content of the sediment were correlated with climatic change. The cold climate between 25,000 and 21,000 years ago caused little runoff, snow accumulation on the mountains, and rapid substantial glacial advances; this period of cold climate resulted in a slow sedimentation rate (0.20 millimeter per year) and in a small organic-carbon content in the sediment. Also, organic-carbon accumulation rates in the lake during this period were slow. The most recent period of slow sedimentation rate and small organic-carbon content occurred between 10,000 and 5500 years ago, indicative of low lake stage and dry climatic conditions. This period of dry climate also was evidenced by dry conditions for Lake Lahontan in Nevada and Searles Lake in California, as cited in the literature. Walker Lake filled rapidly with water between 5500 and 4500 years ago. The data published in this report was not produced under an approved Site Investigation Plan (SIP) or Study Plan (SP) and will not be used in the licensing process. 10 refs., 3 figs., 2 tabs

    1992-01-01

    This paper reports that the United States and the Soviet Union face critical decisions about the future of plutonium production for nuclear weapons. Both countries could eliminate the economic burden of rebuilding their production complexes by agreeing to ban the production of plutonium for weapons. Such an agreement could also provide important national-security benefits by reinforcing the Non-Proliferation Treaty and by diminishing the ability of both nations to break out of nuclear-arms reduction agreements at a later time - especially if the plutonium in the warheads eliminated by the arms reduction agreements is put under safeguards. A production cutoff would be verifiable

    2016-07-01

    This paper studies how daily routines around media consumption, internet and technologyusage, product preferences or civic engagement mediate likehood of being a user-innovator. Based on the differences in demographic characteristics of consumers and assimilation by them of certain daily routines we conclude that a deeper analysis of day-to-day activities can help distinguishing user-innovators fron non-innovating peers. It is argued that innovationrelated actions are rooted in learned behaviour, can be observed through the daily routines and tell us more on user-innovation experience. We suggest that no individual practice, but instead sets of practices taken in different economic, social and cultural environments can explain how innovations grow and disseminate through the entire economy.

    The invasion separation effect of the free jet structure was found in 1966 at Saclay. In the Downstream Sampling Configuration patended by Campargue (1967), the light fraction is withdrawn from the supersonic central core, by skimming the separating free jet. From experimental and theoretical results obtained for gas and isotopic mixtures, the following points linked to operation and equipment costs, are considered: system description; influence of mass ratio, expansion ratio, nature of separating gas, ratio of upflow to separating jet flow, rarefaction. Fron an uninteresting aspect of Jet Membrane (elimination of background penetration), a new principle has been discovered to produce nozzle beams which may be of great interest for other separation processes involving free jets and/or molecular beams [fr

    The qualitative and quantitative effect of initial conditions (linear and non-linear) and high Mach number (1.3 and 1.45) is studied on the turbulent mixing induced by the Richtmyer-Meshkov instability in idealized ICF conditions. The Richtmyer-Meshkov instability seeds Rayleigh-taylor instabilities in ICF experiments and is one of the factors that contributes to reduced performance of ICF experiments. Its also found in collapsing cores of stars and supersonic combustion. We use the Stony Brook University code, FronTier, which is verified via a code comparison study against the AMR multiphysics code FLASH, and validated against vertical shock tube experiments done by the LANL Extreme Fluids Team. These simulations are designed as a step towards simulating more realistic ICF conditions and quantifying the detrimental effects of mixing on the yield.

    2017-10-01

    Numerical studies of the ablation of neon pellets in tokamaks in the plasma disruption mitigation parameter space have been performed using a time-dependent pellet ablation model based on the front tracking code FronTier-MHD. The main features of the model include the explicit tracking of the solid pellet/ablated gas interface, a self-consistent evolving potential distribution in the ablation cloud, JxB forces, atomic processes, and an improved electrical conductivity model. The equation of state model accounts for atomic processes in the ablation cloud as well as deviations from the ideal gas law in the dense, cold layers of neon gas near the pellet surface. Simulations predict processes in the ablation cloud and pellet ablation rates and address the sensitivity of pellet ablation processes to details of physics models, in particular the equation of state.

    Studied were the effects of grain size and the presence of cellular dislocation structure on strength and plastic characteristies of TSM-6 low-alloyed molybdenum during short-term tests in the temperature range fron 20 to 1300 deg C. Structure refining results in considerable increase in short-term strength within the termperature range studied. Ressitance of a crystal lattice to dislocation motion and the Ky parameter in the Hall-Petch equation decreases with the temperature increase. Specific elongation (delta) with increasing the test temperature changes in a curve with the maximum for recrystallized metal and in a curve with minimim for metal with previously formed cellular structure. During the short-term tests the properties of metal with a cellular duslocation structure with provision for a low value of cold brittleness temperature are considered preferable in the whole temperature range studied

    1979-01-01

    The Main Accelerator display system for the Fermilab accelerator gathers charge data and displays it including processed transfer efficiencies of each of the accelerators. To accomplish this, strategically located charge converters monitor the circulating internal beam of each of the Fermilab accelerators. Their outputs are processed via an asynchronously triggered, multiplexed analog-to-digital converter. The data is converted into a digital byte containing address code and data, then stores it into two 16-bit memories. One memory outputs the interleaved data as a data pulse train while the other interfaces directly to a local host computer for further analysis. The microprocessor based display unit synchronizes displayed data during normal operation as well as special storage modes. The display unit outputs data to the fron panel in the form of a numeric value and also makes digital-to-analog conversions of displayed data for external peripheral devices. 5 refs

We analysed coral and molluscan fossil assemblages from reefs near Bocas del Toro, Panama to construct a timeline of ecological change from the 19th century-present. We report large changes before 1960 in coastal lagoons coincident with extensive deforestation, and after 1960 on offshore reefs. Striking changes include the demise of previously dominant staghorn coral Acropora cervicornis and oyster Dendrostrea frons that lives attached to gorgonians and staghorn corals. Reductions in bivalve size and simplification of gastropod trophic structure further implicate increasing environmental stress on reefs. Our paleoecological data strongly support the hypothesis, from extensive qualitative data, that Caribbean reef degradation predates coral bleaching and disease outbreaks linked to anthropogenic climate change. © 2012 Blackwell Publishing Ltd/CNRS.

    Detailed numerical studies of the propagation and merger of high-Mach-number plasma jets and the formation and implosion of plasma liners have been performed using the FronTier code in support of the Plasma Liner Experiment-ALPHA (PLX- α) project. Physics models include radiation, physical diffusion, plasma-EOS models, and an anisotropic diffusion model that mimics deviations from fully collisional hydrodynamics in outer layers of plasma jets. Detailed structure and non-uniformity of plasma liners of due to primary and secondary shock waves have been studies as well as averaged quantities of ram pressure and Mach number. Synthetic data from simulations have been compared with available experimental data from a multi-chord interferometer and survey and high-resolution spectrometers. Numerical studies of the sensitivity of liner properties to experimental errors in the initial masses of jets and the synchronization of plasma gun valves have also been performed. Supported by the ARPA-E ALPHA program.

    Eight month old male C57BL6 mice were exposed without anesthesia to whole-body irradiation in circular holders. The mice were tested for behavioral decrements after 0.5 and 50 rads of Fe particle irradiation at 6 and 12 months post irradiation to obtain long term results. A standard maze was used and the animals were timed for completion thereof. A string test also was administered to the mice, testing their ability to grasp and move along a string to safety. The results from animals exposed to 50 rads were significantly different from [correction of fron] control results to p = brain) and the retina were examined for ultrastructural changes. The ultrastructural changes were similar to those we found in our Cosmos 782, 936 and in our Argon experiments. The mouse data indicate that iron particles were able to induce long term changes in the central nervous system which lead to behavioral impairment.

  10. Turbulent mixing in nonreactive and reactive flows

    CERN Document Server

    1975-01-01

    Turbulence, mixing and the mutual interaction of turbulence and chemistry continue to remain perplexing and impregnable in the fron­ tiers of fluid mechanics. The past ten years have brought enormous advances in computers and computational techniques on the one hand and in measurements and data processing on the other. The impact of such capabilities has led to a revolution both in the understanding of the structure of turbulence as well as in the predictive methods for application in technology. The early ideas on turbulence being an array of complicated phenomena and having some form of reasonably strong coherent struc­ ture have become well substantiated in recent experimental work. We are still at the very beginning of understanding all of the aspects of such coherence and of the possibilities of incorporating such structure into the analytical models for even those cases where the thin shear layer approximation may be valid. Nevertheless a distinguished body of "eddy chasers" has come into existence. T...

    In this thesis we have put the first constraints on t he fundamental parameters of the Randall-Sundnun model of extra dimensions, $k / M_{pl}$ which is proportional to the coupling of the graviton to the standard model fields and $M_G$ which is the mass of the first excited state of t he Kaluza-Klein graviton. The analysis perfomed on Monte carlo sample of the sign al allowed to find an error in the PYTHIA generator. The elaboration of an independent generator dedicated for this special analysis helped to find out and correct the error. The data sample used for the an alysis covers the period running fron1 november 2002 up to July 2002 taken by the Dzero collaboration at Tevatron, which corresponds to an accumulated lumninosity of 107,8 pb-1 . The search for the graviton in the dinmon channel allowed to rnea.sure the Z production cross-section t irnes the branching ratio in dimuons.

    Many of the processing steps in the nuclear fuel cycle generate aqueous effluent streams bearing contaminants that can, because of their chemical or radiological properties, pose an environmental hazard. Concentration of such contaminants must be reduced to acceptable levels before the streams can be discharged to the environment. Two classes of contaminants, nitrates and heavy metals, are addressed in this study. Specific techniques aimed at the removal of nitrates and radioactive heavy metals by biological processes are being developed, tested, and demonstrated. Although cost comparisons between biological processes and current treatment methods are presented, these comparisons may be misleading because biological processes yield environmentally better end results which are difficult to price. However, a strong case is made for the use of biological processes for removing nitrates and heavy metals fron nuclear fuel cycle effluents. The estimated costs for these methods are as low as, or lower than, those for alternate processes. In addition, the resulting disposal products - nitrogen gas, CO 2 , and heavy metals incorporated into microorganisms - are much more ecologically desirable than the end products of other waste treatment methods

    1987-01-01

    Studies of Jovian perturbations of the orbits of long-period comets led to the concept of the Oort cloud of 180 billion comets at 50,000-150,000 AU from the sun. Several comets are induced to move toward the sun every million years by the passage of a star at a distance of a few light years. The location of the cloud has since been revised to 20,000-100,000 AU, and comets are now accepted as remnant material fron the proto-solar system epoch. The galactic disk and random, close-passing stars may also cause rare, large perturbations in the orbits of the cloud comets, sending large numbers of comets through the inner solar system. The resulting cometary storm is a candidate cause for the wholesale extinction of dinosaurs in the Cretaceous-Terniary transition due to large number of planetesimals, or one large comet, striking the earth, in a short period of time. The IRAS instruments have detected similar clouds of material around other stars

    1981-03-01

    High pressure fluorescence studies fron 0-10 kbar have been performed on electron donor-acceptor (EDA) complexes of s-tetracyanobenzene (TCNB) with a series of aromatic hydrocarbons. Four solvents were used, 2,2,4,4,6,8,8 heptamethylnonane (HMN), methylcyclohexane (MCH), 2,6,10,14 tetramethylpentadecane (TMPD), and a mixture of MCH and HMN. A viscosity range from 0.006 to 10 000 poise was covered at constant temperature. As pressure (viscosity) increased the fluorescence spectrum shifted from one dominated by emission from the equilibrium (EQ) excited singlet state to one dominated by Franck-Condon (FC) singlet emission. Lifetime measurements for the complexes of o-xylene and p-xylene with TCNB as well as one mesitylene complex yielded the two radiative rates (kEQ and kFC) as well as the rate of internal conversion from FC to the EQ excited state to (kIC). The results are discussed in terms of the rate of relaxation of the solvent compared with the rate kFC. It was found that kIC correlated very well with the solvent viscosity.

  19. Concurrent applicative implementations of nondeterministic algorithms

    Energy Technology Data Exchange (ETDEWEB)

    Salter, R

    1983-01-01

    The author introduces a methodology for utilizing concurrency in place of backtracking in the implementation of nondeterministic algorithms. This is achieved in an applicative setting through the use of the Friedman-Wise multiprogramming primitive frons, and a paradigm which views the action of nondeterministic algorithms as one of data structure construction. The element by element nondeterminism arising from a linearized search is replaced by a control structure which is oriented towards constructing sets of partial computations. This point of view is facilitated by the use of suspensions, which allow control disciplines to be embodied in the form of conceptual data structures that in reality manifest themselves only for purposes of control. He applies this methodology to the class of problems usually solved through the use of simple backtracking (e.g. 'eight queens'), and to a problem presented by Lindstrom (1979) to illustrate the use of coroutine controlled backtracking, to produce backtrack-free solutions. The solution to the latter illustrates the coroutine capability of suspended structures, but also demonstrates a need for further investigations into resolving problems of process communication in applicative languages. 14 references.

EUCAARI started on 1 January 2007 and ended on 31 December 2010 leaving a rich legacy including: (a a comprehensive database with a year of observations of the physical, chemical and optical properties of aerosol particles over Europe, (b comprehensive aerosol measurements in four developing countries, (c a database of airborne measurements of aerosols and clouds over Europe during May 2008, (d comprehensive modeling tools to study aerosol processes fron nano to global scale and their effects on climate and air quality. In addition a new Pan-European aerosol emissions inventory was developed and evaluated, a new cluster spectrometer was built and tested in the field and several new aerosol parameterizations and computations modules for chemical transport and global climate models were developed and evaluated. These achievements and related studies have substantially improved our understanding and reduced the uncertainties of aerosol radiative forcing and air quality-climate interactions. The EUCAARI results can be utilized in European and global environmental policy to assess the aerosol impacts and the corresponding abatement strategies.

    Full Text Available ABSTRACT In early March 2015, three males and two females of one unknown species of Drosophila were collected from a compost pile and some garbage cans in the west region of the city of São Paulo, state of São Paulo, Brazil. Morphologically it is easily identified by the presence of the following conspicuous features: a brownish dorsal stripe along pleura, an entirely iridescent silvery-whitish frons when seen directly from the front, and a row of cuneiform setae on anteroventral side of femur of foreleg; the former two traits being more evident in males. The species was easily reared in a modified banana-agar medium and two isofemale lines were established allowing to obtain mitotic cells showing a diploid chromosome number of 2n = 8. Based both on morphological and chromosomal features, in addition to the geographical distribution, we concluded that the unknown flies belong to Drosophila nasuta Lamb, 1914, a tropical species of the nasuta subgroup of the Drosophila immigrans species group. Photomicrographs of male imagines, terminalia, mitotic and meiotic metaphase plates, as well as of female mitotic metaphase, are included.

It is based on multichannel forehead bioelectric signals acquired by placing three pairs of electrodes (physical channels) on the Fron-tails and Temporalis facial muscles. The acquired signals are passes through a parallel filter bank to explore three different sub-bands related to facial electromyogram, electrooculogram and electroencephalogram. The root mean features of the bioelectric signals analyzed within non-overlapping 256 ms windows were extracted. The subtractive fuzzy c-means clustering method (SFCM) was applied to segment the feature space and generate initial fuzzy based Takagi-Sugeno rules. Then, an adaptive neuro-fuzzy inference system is exploited to tune up the premises and consequence parameters of the extracted SFCMs. rules. The average classifier discriminating ratio for eight different facial gestures (smiling, frowning, pulling up left/right lips corner, eye movement to left/right/up/down is between 93.04% and 96.99% according to different combinations and fusions of logical features. Experimental results show that the proposed interface has a high degree of accuracy and robustness for discrimination of 8 fundamental facial gestures. Some potential and further capabilities of our approach in human-machine interfaces are also discussed. (author)

    Dysexecutive impairment is a common problem after brain injury, particularly after damage to the lateral surface of the frontal lobes. There is a large literature describing the cognitive deficits associated with executive impairment after dorsolateral damage; however, little is known about its impact on emotional functioning. This case study describes changes in a 72-year-old man (Professor F) who became markedly dysexecutive after a left fron-to-parietal stroke. Professor F's case is remarkable in that, despite exhibiting typical executive impairments, abstraction and working memory capacities were spared. Such preservation of insight-related capacities allowed him to offer a detailed account of his emotional changes. Quantitative and qualitative tools were used to explore changes in several well-known emotional processes. The results suggest that Professor F's two main emotional changes were in the domain of emotional reactivity (increased experience of both positive and negative emotions) and emotion regulation (down-regulation of sadness). Professor F related both changes to difficulties in his thinking process, especially a difficulty generating and manipulating thoughts during moments of negative arousal. These results are discussed in relation to the literature on executive function and emotion regulation. The relevance of these findings for neuropsychological rehabilitation and for the debate on the neural basis of emotional processes is addressed.

  10. Subgrid models for mass and thermal diffusion in turbulent mixing

    2010-01-01

    We propose a new method for the large eddy simulation (LES) of turbulent mixing flows. The method yields convergent probability distribution functions (PDFs) for temperature and concentration and a chemical reaction rate when applied to reshocked Richtmyer-Meshkov (RM) unstable flows. Because such a mesh convergence is an unusual and perhaps original capability for LES of RM flows, we review previous validation studies of the principal components of the algorithm. The components are (i) a front tracking code, FronTier, to control numerical mass diffusion and (ii) dynamic subgrid scale (SGS) models to compensate for unresolved scales in the LES. We also review the relevant code comparison studies. We compare our results to a simple model based on 1D diffusion, taking place in the geometry defined statistically by the interface (the 50% isoconcentration surface between the two fluids). Several conclusions important to physics could be drawn from our study. We model chemical reactions with no closure approximations beyond those in the LES of the fluid variables itself, and as with dynamic SGS models, these closures contain no adjustable parameters. The chemical reaction rate is specified by the joint PDF for temperature and concentration. We observe a bimodal distribution for the PDF and we observe significant dependence on fluid transport parameters.

    To analyse results of full time occlusion therapy for amblyopia in children older than 6 years. This was a retrospective consecutive case series analysis of children treated for amblyopia at a tertiary care center. All children received full time occlusion (FTO) for the dominant eye. Eighty-eight children older than 6 years at the time of initiation of therapy were included. Age at initiation of therapy ranged from 6 to 20 years (9.45 +/- 3.11 years). Forty-two children (47.7%) had strabismic amblyopia, 37 (42.0%) had anisometropic amblyopia and 9 (10.2%) had a combination of strabismic and anisometropic amblyopia. Eighty out of 88 eyes (90.0%) had improvement in visual acuity following FTO. Visual acuity (VA) improved from 0.82 +/- 0.34 at presentation to 0.42 +/- 0.34 (P amblyopia, VA improved from 0.81 +/- 0.42 to 0.42 +/- 0.39 (P amblyopia, visual acuity of the amblyopic eye improved fron 0.82 +/- 0.24 to 0.36 +/- 0.29 (Pocclusion was 8.37 +/- 1.78 months. Occlusion therapy yields favorable results in strabismic and/or anisometropic amblyopia, even when initiated for the first time after 6 years of age. After 12 years of age, some children may still respond to occlusion of the dominant eye.

    A nested case-control study was conducted among workers employed between 1943 and 1977 at two nuclear facilities to investigate the possible association of primary malignant neoplasms of the central nervous system (CNS) with occupational exposure to ionizing radiation from external and internal sources. Eighty-nine white male and female workers, who according to the information on death certificates dies of primary CNS cancers, were identified as cases. Four matched controls were selected for each case. External radiation exposure data were available from film badge readings for individual workers, whereas radiation dose to lung from internally deposited radionuclides, mainly uranium, was estimated from area and personnel monitoring data and was used in analyses in lieu of the dose to the brain. Matched sets were included in the analyses only if information was available for the case and at least one of the corresponding controls. Thus, the analyses of external radiation included 27 cases and 90 matched controls, and 47 cases and 120 matched controls were analyzed for the effects of radiation from internally deposited uranium. No association was observed between deaths fron CNS cancers and occupational exposure to ionizing radiation from external or internal sources. However, due to the small number of monitored subjects and low doses, a weak association could not be ruled out. 43 refs., 1 fig., 15 tabs

    Three-dimensional simulations of the formation and implosion of plasma liners for the Plasma Jet Induced Magneto Inertial Fusion (PJMIF) have been performed using multiscale simulation technique based on the FronTier code. In the PJMIF concept, a plasma liner, formed by merging of a large number of radial, highly supersonic plasma jets, implodes on the target in the form of two compact plasma toroids, and compresses it to conditions of the nuclear fusion ignition. The propagation of a single jet with Mach number 60 from the plasma gun to the merging point was studied using the FronTier code. The simulation result was used as input to the 3D jet merger problem. The merger of 144, 125, and 625 jets and the formation and heating of plasma liner by compression waves have been studied and compared with recent theoretical predictions. The main result of the study is the prediction of the average Mach number reduction and the description of the liner structure and properties. We have also compared the effect of different merging radii. Spherically symmetric simulations of the implosion of plasma liners and compression of plasma targets have also been performed using the method of front tracking. The cases of single deuterium and xenon liners and double layer deuterium - xenon liners compressing various deuterium-tritium targets have been investigated, optimized for maximum fusion energy gains, and compared with theoretical predictions and scaling laws of [P. Parks, On the efficacy of imploding plasma liners for magnetized fusion target compression, Phys. Plasmas 15, 062506 (2008)]. In agreement with the theory, the fusion gain was significantly below unity for deuterium - tritium targets compressed by Mach 60 deuterium liners. In the most optimal setup for a given chamber size that contained a target with the initial radius of 20 cm compressed by 10 cm thick, Mach 60 xenon liner, the target ignition and fusion energy gain of 10 was achieved. Simulations also showed that

    A Supercritical-water Cooled Power Reactor (SCPR) development project (Feb. 2001- Mar. 2005) is being performed by a joint team consisting of Japanese universities and nuclear venders with a national fund. The main objective of this project is to provide technical information essential to demonstration of SCPR technologies through concentrating three sub-themes: 'plant conceptual design', 'thermohydraulics', and 'material and water chemistry'. The target of the 'plant conceptual design sub-theme' is simplify the whole plant systems compared with the conventional LWRs while achieving high thermal efficiency of more than 40 % without sacrificing the level of safety. Under the 'thermohydraulics sub-theme', heat transfer characteristics of supercritical-water as a coolant of the SCPR are examined experimentally and analytically focusing on 'heat transfer deterioration'. The experiments are being performed using fron-22 for water at a fossil boiler test facility. The experimental results are being incorporated in LWR analytical tools together with an extended steam/R22 table. Under the 'material and water chemistry sub-theme', material candidates for fuel claddings and internals of the SCPR are being screened mainly through mechanical tests, corrosion tests, and simulated irradiation tests under the SCPR condition considering water chemistry. In particular, stress corrosion cracking sensitivity is being investigated as well as uniform corrosion and swelling characteristics. Influences of water chemistry on the corrosion product characteristics are also being examined to find preferable water condition as well as to develop rational water chemistry controlling methods.

    Conversion of nuclear power plants fron analog to digital control systems will require careful design, testing, and integration of the control algorithms, the software which implements the algorithms, the digital instrumentation, the digital communications network, and analog/digital device interfaces. Digital control systems are more flexible than their analog counterparts, and therefore greater attention must be paid by the customer to all stages of the control system design process. This flexibility also provides the framework for development of significant safety and reliability are inherant aspects of the chosen design processes. Digital control algorithms are capable of improving their performance by on-line self-tuning of the control parameters. It is therefore incumbant on system designers to choose self-tuning algorithms for power plant control. Implementation of these algorithms in software required a careful software design and development process to minimize errors in interpretation of the engineering design and prevent the inclusion of programming errors during software production. Digital control system and communications software must exhibit sufficient ''fault tolerance'' to maintain some level of safe plant operation or execute a safe plant shutdown in the event of both hard equipment failures and the appearance of software design faults. A number of standardized digital communications protocols are available to designers of digital control systems. These standardized digital communications protocols provide reliable fault tolerant communication between all digital elements of the plant control system and can be implemented redundantly to further enhance power plant operational safety. 5 refs., 11 figs., 1 tab

  20. Use of environmental isotopes to investigate the interconnections between the Reno River and groundwater (Northern Italy)

    1975-01-01

    This research is part of the investigations carried out to assess the environmental impact of the Brasimone site in the upper reaches of the Reno River, where a nuclear research plant is under construction. This plant might imply a risk of contamination of the Reno River water by radioactive wastes. Environmental isotope techinques were used to study the interconnections between the Reno River and groundwater and qualitatively to define the flow dynamics between the surface waters and groundwater in the area of Bologna. The Reno River flows across an aquifer consisting of an irregular succession of alluvial beds of sandy gravel, sands and clayey or sandy silts of varying thicknesses. At the two pumping stations of Borgo Panigale and Tiro a Segno, the tritium and 14 C contents of the groundwater regularly decrease with increasing distance from the Reno River. This indicates that there is a contribution of recent water recharged fron the river, and that such a contribution is higher in Borgo Panigale than in Tiro a Segno. At the pumping station of San Vitale di Reno, only recently put into operation and at a distance from the river greater than that of the other two stations, there is no indication of recharge of recent river water. Stable isotopes also show a slight variation with the distance from the river, in agreement with the fact that deep groundwater is a mixture in variable proportions of two components, one of them originating from the river. All these results were possible to achieve only by means of nevironmental isotope techniques. (author)

    Full Text Available Este ensayo examina tres relatos de escritoras chilenas publicados entre 1986 y 1993 en los que las protagonistas aparecen representadas como mujeres enfermas. Esta forma de representación, que subraya la materialidad del cuerpo, sugiere una concepción de la subjetividad en la que cuerpo y mente no pueden concebirse separadamente. Al enfocarse en personajes femeninos que sufren de desórdenes relacionados con la dieta, bulimia y anorexia, y en una madre enferma y su hija que está por dar a luz, estas narraciones muestran diversos modos en que las protagonistas se relacionan con su medio social, especialmente en lo que se refiere a su posición como mujeres. Los tres textos ofrecen diferentes reacciones frente a las expectativas sociales en cuanto a los roles femeninos prescritos, y varios grados de resistencia frente esos modelos. This essay examines three stories by Chilean women writers published between 1983 and 1993, in which the protaginists appear in the condition of sick women. The form of representation, underscoring the materiality of the body suggests a view of subjectivity in which body and mind cannot be conceived as separate. In focusing on femenine characters suffering fron disorders related to diet, bulimia and anorexia, and also on a sick mother with a daughter who is about to give birth, these narratives show different ways for the protagonists to relate to their respective social milieu, specially in what affects their gender condition. The three texts offer different reations to social expectations deriving from established femenine roles with various degrees of resistance to those prescribed models.

    Many insects use chemicals synthesized in exocrine glands and stored in reservoirs to protect themselves. Two chemically defended insects were used as models for the development of a new rapid analytical method based on desorption atmospheric pressure photoionization-mass spectrometry (DAPPI-MS). The distribution of defensive chemicals on the insect body surface was studied. Since these chemicals are predominantly nonpolar, DAPPI was a suitable analytical method. Repeatability of DAPPI-MS signals and effects related to non-planarity and roughness of samples were investigated using acrylic sheets uniformly covered with an analyte. After that, analytical figures of merit of the technique were determined. The spatial distribution of (E)-1-nitropentadec-1-ene, a toxic nitro compound synthesized by soldiers of the termite Prorhinotermes simplex, was investigated. Then, the spatial distribution of the unsaturated aldehydes (E)-hex-2-enal, (E)-4-oxohex-2-enal, (E)-oct-2-enal, (E,E)-deca-2,4-dienal and (E)-dec-2-enal was monitored in the stink bug Graphosoma lineatum. Chemicals present on the body surface were scanned along the median line of the insect from the head to the abdomen and vice versa, employing either the MS or MS(2) mode. In this fast and simple way, the opening of the frontal gland on the frons of termite soldiers and the position of the frontal gland reservoir, extending deep into the abdominal cavity, were localized. In the stink bug, the opening of the metathoracic scent glands (ostiole) on the ventral side of the thorax as well as the gland reservoir in the median position under the ventral surface of the anterior abdomen were detected and localized. The developed method has future prospects in routine laboratory use in life sciences. Copyright © 2015 Elsevier B.V. All rights reserved.

    El Hierro Island (Canary Islands, Spain) has undergone a submarine eruption a few kilometers to its southeast, detected October 10, on the rift alignment that cuts across the island. However, the seismicity level suddenly increased around July 17 and ground deformation was detected by the only continuously observed GNSS-GPS (Global Navigation Satellite Systems - Global Positioning System) benchmark FRON in the El Golfo area. Based on that information several other GNSS-GPS benchmarks were installed, some of which continuously observed as well. A normal vector analysis was applied to these collected data. The normal vector magnitude variation identified local extension-compression regimes, while the normal vector inclination showed the relative height variation between the three benchmarks that define the plan to which normal vector is analyzed. To accomplish this analysis the data was previously processed to achieve positioning solutions every 30 minutes using the Bernese GPS Software 5.0, further enhanced by a Discrete Kalman Filter, giving an overall millimeter level precision. These solutions were reached using the IGS (International GNSS Service) ultra-rapid orbits and the double-differenced ionosphere-free combination. With this strategy the positioning solutions were attained in near real-time. Later with the IGS rapid orbits the data was reprocessed to provide added confidence to the solutions. Two triangles were then considered, a smaller one located in the El Golfo area within the historically collapsed caldera, and a larger one defined by benchmarks placed in Valverde, El Golfo and La Restinga, the town closest to the eruption's location, covering almost the entire Island's surface above sea level. With these two triangles the pre-eruption and post-eruption deformation suffered by El Hierro's surface will be further analyzed.

    For existing plantings and management, the availability of residues and energy in the forest and from the wood processing industry in the United Kingdom has been shown to be 885kt/y for 1977 and 2520kt/y for 2000. Biomass available in 2000 from thinning of existing forests is likely to range from 600kt/y up to much higher levels if the markets for small roundwood remain weak. Energy plantations of two types have been examined in detail, coppice for the better conditions, single stem growth for the more difficult sites. Suitable species have been evaluated, and areas of land which are at present only partially utilized for food production have been identified. Depending on the conditions, yields are likely to vary from 5 to 20 t/ha/y giving a potential yield of forest biomass of 16M dry t/y from 1.5M ha. Costs of biomass per uit energy, on-site, from residues, processing, thinnings and plantations are less than the current price of coal.

    This study evaluates the effectiveness of traditional bone setting (TBS) in chronic neck pain (cNP) compared with conventional physiotherapy (PT) and massage (M). This was a randomized clinical trial. Working-aged employed subjects with cNP (n = 105; 37 men and 68 women; mean age, 41.5 years) were randomized into TBS, PT, and M groups. Follow-up times were 1, 6, and 12 months after the treatments. Neck pain intensity (visual analog scale), perceived disability (Neck Disability Index [NDI]), and neck spine mobility measurements were used as outcomes. Global assessment was evaluated by the subjects (scale from -1 to +10). Data were analyzed using time (pre and post) by group (TBS, PT and M), 2- way analysis of variance for repeated measures. Neck pain decreased and NDI scores improved in all groups 1 month after the treatment (P better after TBS. Neck spine mobility in rotation movements tended to improve significantly better and the frons-knee distance improved more after TBS. One year later, both NDI and neck pain were significantly better after TBS than in reference groups. A significant improvement was reported by 40% to 45.5% of subjects in the PT and M groups and by 68.6% in the TBS group. Bone setters' ability to communicate and to interact with patients was evaluated significantly higher. In the TBS group, the number of sick days was minimal as was the use of painkillers during 1-year follow-up compared to that in the reference groups. Traditional bone setting, which is a soft manual mobilization technique focusing on the muscles, joints, and ligaments, appears to be effective in cNP. Two thirds of subjects experienced it as beneficial, and it seems to be able to improve disability and pain in patients with cNP. Subjective and partially objective benefits of TBS were found in those patients more than after other interventions, and the effects lasted at least for 1 year.

    Full Text Available Public policies is the context of analysis chosen in this article. Specifically, the one refering to alcohol, tobacco and medicament. Public policies make an approach towards theoretical settings which raise political debates and practical porcesses from empirical analysis. The genre perspective-as social construction-points out the visibility of women, the equal participation in institutions, the care of language and transversality. Alcohol, tobacco and medicament are substances which have ,as a commom characteristic, the manipulation fron powerful and complex economical interests that can, and indeed, do influence both public policies and political profitability. The main point of the article is a warning about some of the consequences of "invisibility" for women. Este trabajo quiere introducir una reflexión en torno al contexto de análisis que se abre en torno al alcohol, el tabaco y los fármacos, el de las políticas públicas. Frente al ámbito de política criminal que ha de abordarse en el tratamiento de las drogas denominadas ilegales, las políticas públicas se abren a marcos teóricos que permiten una ordenación tipológica de las políticas públicas. Y, en este ámbito, intentaremos apuntar en relación con el tema estudiado cómo cabe un análisis empírico de las políticas públicas en tanto en cuanto permiten un primer proceso de definición de problemas y de acceso de cuestiones a la agenda pública de actuación; con posterioridad, un proceso de negociación y, en tercer término, la articulación de escenarios organizativos y de gestión. En este proceso, todos los actores políticos interactúan en función de intereses, ideas y valores ligados a distribuciones cambiantes de poder y con reglas más o menos formalizadas dentro de una clave institucional.

    Two methods were used in a study of liquid-vapor equilibrium of VOCl 3 -Si 2 OCl 6 (1) and VOCl 3 -CCl 3 COCl (2) systems. The first, ebulliometric method was used for determining the relationship saturated vapor pressure in the range from 450-500 to 1450-1500 mm Hg and the temperature which is in the range from 100-110 to 150-160 deg C. The data on saturated vapor pressure of pure substances and their mixtures were interpreted by the least squares method according to an equations of the type lgP=A-B/T. For 760 mm Hg isobar the dependence of the b.p. of system 1 on the concentration of its components considerably deviates fron the ideal state. In this case positive azeotrope is formed (b.p. 126.5 deg C) containing 83.5% mole VOCl 3 . The Van Laar euqation was used in calculating the relative volatility. At 760 mm Hg pressure in I, Si 2 OCl 6 is more volatile, the difference between the normal b.p. of VOCl 6 (127.7 deg C) and that of the azeotropic mixture (126.5 deg C) being only 1.2 deg C. The Rayleigh distillation method was used for direct determination of the volatility of this system. The average value for αsub(Si 2 OCl 6 /VOCl 3 ) was found to be 1.44. It accords well with the value of 1.47 obtained from an extrapolation of results for pure VOCl 3 on the basis of the ebulloimetric measurements. In the case of system 2 a considerable positive deviation from the ideal state was observed within the entire range of concentrations. Calculations of the activity coefficients for the components of this system, the composition of the vapor phase and the relative volatility were made with the aid of the Dugem-Margulis equation. The value for the relative volatility αsub(CCl 3 COCl/VOCl 3 ), as extrapolated for pure VOCl 3 , was 1.8. No direct measurements of α were made in this case owing to difficulties in analysis of the two components

    Full Text Available In the outskirts of Narvacles (county of Bages, province of Barcelona, the remains of a small medieval church, desecrated in 1936 and abandoned to its fortune after the civil war, ran the risk of disappearing. In 1984, the municipal government asked the Diputació for help to stop the deterioration and offer some solution for the preservation of the remains. The initial scientific work discovered that structures from a Roman villa from the I century had been used in the construction of the chapel, an that the first building from the XIII century was expanded in the XVII, taking advantage of some of the elements of the primitive Romanesque portal. The solution projected was based on the consolidation of the ruin, and the construction of a small covered space —that recalI the volume of the first temple— delimited by the preserved medieval walls and other new ones. A platform separates this from the Roman remains. The effort was topped off with a small square in fron of the now disappeared north façade.

    The island of El Hierro (278 Km2), is the smallest, the southwesternmost and the youngest island (˜1.12 My) of the Canarian archipelago. The main geological characteristics of El Hierro consist on the presence of three convergent ridges of volcanic cones on a truncated trihedron shape and giant landslides between the three rift zones, being the most recent El Golfo on the northwest flank of the island. On July 2011 an anomalous seismic activity at Hierro Island started and suggested the initial stage of a volcanic unrest in the volcanic system. On October 10, after the occurrence of more than 10,000 earthquakes, a submarine eruption started. Evidences of this submarine volcanic eruption were visible on the sea surface to the south of La Restinga village, at the south of the island, in the form of large light-green coloured area, turbulent gas emission and the appearance of steamy volcanic fragments three days later. As part of its volcanic surveillance activities, the Instituto Volcanologico de Canarias (INVOLCAN) started a hydrogeochemical monitoring program on August 2011 in order to evaluate the temporal evolution of several physico-chemical parameters of the ground water system of El Hierro. Four observation sites were selected: three wells on the north of the island, where the seismic activity was located at the beginning of the volcano-seismic unrest (SIMO, FRON and PADO) and one horizontal well (gallery) in the south (TACO). Ground water sampling is being regularly collected, three times per week, at each observation site, and in-situ measurements of pH, conductivity and temperature measurements are performed. After 6 month of monitoring, no significant changes have been observed on pH and temperature measurements from all the observation sites. However, clear sharp decrease of conductivity was observed at SIMO on October 10 when the seismic tremor started. In addition, the strongest conductivity decrease pattern was observed later on at SIMO and PADO on

Dazu wird eine kurze Übersicht über die funktionellen Einheiten des Pycnodontierschädels gegeben. Die Kinematik des Nahrungsaufnahmeapparates der Pycnodontier stellt einen Übergang von der einfachen, stereotypischen Kinematik primitiver Actinopterygier zu der modulierenden Kinematik fortschrittlicher Teleosteer dar und wird hier als limitierte, modulierende Kinematik bezeichnet. Zwei structurelle Spezialisationen, die bei Halecostomi entwickelt sind (Operculum mit distinkten m. levator operculare und das Interoperculare mit dem interoperculare Ligament fehlen bei Pycnodontiern, wogegen sie die zwei primitiven Verbindungen zwischen den epaxialen Muskeln und dem Neurocrani-um und zwischen den hypaxialen Muskeln, dem Cleithrum und dem Sternohyoidmuskel für die direkte Unterkieferabsenkung beibehalten. Fortschrittliche Pycnodontier entwickeln aber eine neue Struktur (bewegliches Maxillare und Premaxillare zur Erweiterung des buccopharyngealen Raumes, die bei Halecomorphen als auch ursprünglichen Pycnodontiern (z.

    Fruit production plays an important role in Africa's economy. In Ghana, mango is targeted as one of the next non-traditional export crop that is expected to fetch the highest foreign exchange for the country and replace cocoa. Ghana's current production is said to have increased from 6,800 tonnes in 2007 to about 7000 tonnes in 2010. However, the African invader fruit fly, Bactrocera invadens, is causing high yield losses as an important quarantine pest and has brought some setback in the mango trade between Ghana and their exporting destinations. Imported commercial protein hydrolysate bait for controlling the flies constitutes the highest cost component of the control programme, excluding cost of labour. The baits are exhorbitant for local farmers and seldom available. This setback has called for the need to design and implement efficient and cost-effective control regimes for managing this pest. The objective of the study was to explore the development of locally produced, cheap and efficient baiting system using brewery yeast wastes and coloured cylinder traps to attract and control this quarantine pest. A 1 ha study area was selected within DORMEHSCO FARM, a mango orchard at Somanya in the Eastern region of Ghana with the Keith mango variety for the study. Local sources of Guiness, Beer and Pito yeast wastes were collected into Winchester bottles and subjected to pasteurisation. Papain enzyme was added to maximize yeast cell autolysis at 70 degrees celcius for 9 hours. The Micro-Kjeldahl apparatus was used to determine the percentage protein in each waste. Transparent cylinder traps with three different colours of lids (red, yellow and green) and three 3cm diameter round holes referred to as coloured traps were used to dispense the baits. The traps were labelled according to the type of bait and trap colour combination. The trials were conducted in two successive peak fruiting seasons fron October to November, 2011 (minor season and then from April to June

De esta manera se puede determinar lo importante que puede ser un cambio estructural en la función de esta proteína. NADPH oxidase system is an enzymatic electron transport complex localized in the membrane of phagocytic cells. Several proteins belong to this system: A flavocytochrome b558, formed by a b chain (gp91.phox and an a chain (p22.phox and, at least, 3 cytosolic proteins (p47.phox, p67.phox and p40 phox. Genetic alteration in any of these proteins causes the syndrome of Chronic Granulomatous Disease (CGD. Characterization of mutations in patients with CGD has been fundamental to elucidate the structure and function of NADPH oxidase system ComponentS. Several findings make p47.phoX an interesting model to study the molecular mechanism involved in regulating the expreSSion and bioChemical function ofthis system. So far, in patients with p47.phoX defect a deletion of dinucleotide GT has been foUnd at the beginning of exon 2; most of them are homocygotic for this deletion which is probably due to recombinant events between normal p47.phoX gen and a recently described pseudogen. Any mutation found when diagnosing non.homocygotic patients (gDNA or cDNA may represent a pseudogen change. Therefore, for precise identification of the genetic defect it is necessary to separate the normal gen from the pseudogen and to analyze individual sequences. Non.homocygotic patients posibly have a second mutation in the wild type allele different fron GT deletion. On the other hand, through site. oriented mutagenesis it is posible to modify some of the aminoacids or domains of p47.phoX, which may be essential for its function and relationship with CGD. With this method010gy it is possible to introduce changes in a gen whoSe sequence is thoroughly known and which is amplified; mutants So generated can

  4. A Study of the Relationship between Mulla Sadra's " Extra-Intellectual Order" and Kierkegaard's "Sphere of Religion"

    , Kierkegaard is a known to be a harsh critic of rationalism. He wants to remind his readers of limitations of human reason. Placing faith in the center of Christian thinking, he believed that intellect has no role in religious creed; and that the object of faith has to be paradoxical. Without submission to the paradoxical, the necessary passion and the ground for decision would not be peovided. Submitting to the paradoxical, a passionate human being displays his/her exyreme passion and commitment to the object of his/her faith, which is a paradox, and paradoxical as much as the paradox itself. In Kierkegaard's view, the void arising from the inconsistency of two discrete, and at the same time, subsequent issues (ethical and religious life is filled by an existential issue, namely deapair. Such a despair, he argues, is an existential process swallowing the entire individual existence and is the result of paradoxes and substantial impasses that an individual faces within the extant conditions of his/her own life, becoming the turning point where a human being is detached fron morality and adjoins religion. Such a despair is deliberaye and chosen. Humans cannot be desperate without spliciting despair. When resolving it correctly, an individual would go beyond it righteously. In Islamic view, however, faith is not an anti rational category. In Mulla Sadra's view, faith is inclusive of instinctive knowledge and intuitive knowledge. Faith has various grades, one being intuitive. Another grade is the knowledge of God through argumentative comparison. Although faith is a matter of heart/instinct, the heartfelt/instinctive faith is not exclusive to exploratory knowledge; and knowledge of God through reasoning and arguments could be considered heartfelt/inatinctive faith. He tries to reconcile intellect and religion; or in other words, gnosticism and argumentation. In his specific semantic analytic method, Mulla Sadra links elements seemingly not directly related to the concept of faith
