  5. Genetic-evolutionary studies on cultivated cannas : VI. Origin and evolution of ornamental taxa.

    Khoshoo, T N; Mukherjee, I

    1970-01-01

    Hybridization has played a dominant and decisive role in the origin of ornamental cannas. This has been made possible by the ecospecific differentiation of the parental species, which implies lack of barriers and a good deal of recombination associated with reasonably high fertility.Colour differences between species are controlled by a number of genes and their intensifiers, inhibitors, lethals, etc. From recombination in interspecific hybrids of such a wide range of genes, segregating simultaneously and involving complex segregation, arises a wide array of heterozygous genotypes with new colours and colour combinations, releasing much genetic diversity.Hybridization has also been responsible for transgressive segregation, particularly in length and breadth of staminodia and luxuriance, affecting not only plant height but also flower size. Perhaps the most important single factor responsible for the evolution of ornamental cannas has been the repeated cycles of hybridization which have led to the breakage of size and other barriers; this seems to have been exploited continuously until very large flower size was built up and combined with other useful vegetative and floral characters such as colour and number of flowers per inflorescence, extended blooming period, cold resistance, etc. The efficient vegetative propagation made fixing of the useful genotypes no problem, although they may contain a high degree of heterozygosity and sexual sterility.Along these lines, Année (hybrids between C. indica and C. glauca) and Ehemann (hybrids between C. iridiflora and C. warscwiczii) cannas came into being in 1848 and 1863 respectively. Although both were a distinct improvement over the original species, they were still relatively small-flowered and major improvements came roundabout 1868, when Crozy, Gladiolus or French Dwarf cannas (C. X generalis Bailey) were released. This group arose from hybrids and back crosses of the first two groups and contains diploids

The method of this research consisted of the following steps. First, characterization of canna starch on chemical, physical, and physicochemical properties. The second was formulation and production of some food products. The third was organoleptic test of the products. The results of the study indicated that canna starch sample had total starch of 93.30 % (db,amylose content of 42.49 % (db, and amylopectin content of 50.90 % (db. In canna starch, protein, fat, ash, crude fiber, and reducing sugar were minor components. Canna starch had low water binding capacity (162.15 % and swelling power (9.96 g/g. At concentration of 5 % canna starch had quite low and stable hot paste viscosity (9.67 dPa.s, the viscosity increased to 14,67 dPa.s when cooled. Based on those several characteristics, canna starch can be used as ingredient for some food products, such as cookies and cendol. Hedonic test of the products showed that substitution of canna starch up to 75 % was not significantly different compared to wheat flour for cookies, while 100 % substitution of canna starch was not significantly different compared to rice flour for cendol. It can be concluded that canna starch had potential characteristics to be used for food diversification.

    Starches from two ecotypes of achira roots (Canna edulis Ker-Gawler) were characterized and compared to commercial potato and corn starches. This included scanning electron microscopy (SEM) of starch granules and amylose content determination of starch. Starch solutions or gels were tested by rotational viscometry, Rapid Visco Analyzer (RVA), and texture analysis. Some starch samples were subjected to various treatments: pH reduction, autoclaving at high temperature, and high shear before testing by rotational viscometry. Achira starch showed some unusual properties, such as very large oblong granules (approximately 45-52 microm major axis and approximately 33-34 microm minor axis) and relatively high amylose content (approximately 33-39%). The San Gaban achira ecotype formed high-consistency gels upon cooling, both in RVA study (5% starch) and in texture analysis (8% starch), compared to other starch gels and also exhibited higher thermal resistance to viscosity breakdown.

    Using Canna edulis Ker by-product as raw materials, soluble dietary fiber (SDF) was prepared using six different methods, including chemical, physical-chemical, enzymatic, physical-enzymatic, chemical-enzymatic and physical-chemical-enzymatic methods. As main component in the C. edulis by-product composed of cellulose, glucose converts to other single sugars, which form a series of compounds in the SDF. The treated methods have impact effects on single sugar composition, metal ion content, molecular size distribution, chemical bonds and groups in the structure, thermal property and color of the final product. In view of security, high yield and homogeneity as well as good thermal stability of final product, physical-enzymatic method will be a best choice for the production of SDF from C. edulis by-product. The SDF obtained can be used as dietary supplement and additive in the food industry.

    miRNAs are endogenous small RNA (sRNA) that play critical roles in plant development processes. Canna is an ornamental plant belonging to family Cannaceae. Here, we report for the first time the identification and differential expression of miRNAs in two contrasting flower color cultivars of Canna, Tropical sunrise and Red president. A total of 313 known miRNAs belonging to 78 miRNA families were identified from both the cultivars. Thirty one miRNAs (17 miRNA families) were specific to Tropical sunrise and 43 miRNAs (10 miRNA families) were specific to Red president. Thirty two and 18 putative new miRNAs were identified from Tropical sunrise and Red president, respectively. One hundred and nine miRNAs were differentially expressed in the two cultivars targeting 1343 genes. Among these, 16 miRNAs families targeting 60 genes were involved in flower development related traits and five miRNA families targeting five genes were involved in phenyl propanoid and pigment metabolic processes. We further validated the expression analysis of a few miRNA and their target genes by qRT-PCR. Transcription factors were the major miRNA targets identified. Target validation of a few randomly selected miRNAs by RLM-RACE was performed but was successful with only miR162. These findings will help in understanding flower development processes, particularly the color development in Canna.

    Canna edulis Ker by-product was recycled and utilized after starch extraction. The chemical composition, physical properties and antioxidant activity of the by-product were investigated. The by-product was mainly composed of dietary fiber (54.84% measured by AOAC method), and the insoluble dietary fiber constituted the major fraction. Then, the chemical composition of dietary fiber was tested using modified AOAC and Englyst methods. The results showed that dietary fiber was comprised of cellulose, hemicelluloses (including xyloglucans, arabinoxylans and glucuronoxylans), pectin and lignin. Moreover, the by-product contained relatively high content of phenolic compounds and exhibited a moderate antioxidant activity. In addition, the by-product showed both high water-holding capacity (12.5 mL/g) and oil-holding capacity (14 mL/g), and its suspension exhibited controllable viscosity. Therefore, the by-product from C. edulis is not only a source of dietary fiber but also a functional ingredient for food industry.

    The objective of this study was to investigate the mechanisms of cadmium (Cd) sorption on biochars produced at different temperature (300–600 °C) and their quantitative contribution. The sorption isotherms and kinetics of Cd{sup 2+} sorption on biochars were determined and fitted to different models. The Cd{sup 2+} sorption data could be well described by a simple Langmuir model, and the pseudo second order kinetic model best fitted the kinetic data. The maximum sorption capacity (Q{sub m}) obtained from the Langmuir model for CIB500 was 188.8 mg g{sup −1}, which was greater than that of biochars produced at other temperature. Precipitation with minerals, ion exchange, complexation with surface oxygen-containing functional groups, and coordination with π electrons were the possible mechanisms of Cd{sup 2+} sorption on the biochars. The contribution of each mechanism varied with the pyrolysis temperature. With increasing pyrolysis temperature, the contribution of surface complexation and metal ion exchange decreased from 24.5% and 43.3% to 0.7% and 4.7%, while the contribution of precipitation and Cd{sup 2+}-π interaction significantly increased from 29.7% and 2.5% to 89.5% and 5.1%, respectively. Overall, the precipitation with minerals and metal ion exchange dominated Cd{sup 2+} sorption on the biochars (accounted for 73.0–94.1%), and precipitation with minerals was the primary mechanism of Cd{sup 2+} sorption on the high-temperature biochars (≥ 500 °C) (accounted for 86.1–89.5%). - Highlights: • Sorption capacity of metal on biochars is affected by pyrolysis temperature. • Biochar derived from Canna indica at 500 °C has a high sorption capacity for Cd{sup 2+}. • Cd{sup 2+} sorption on the biochars fits a pseudo second order and Langmuir model. • Precipitation and ion exchange mechanisms dominated Cd{sup 2+} sorption on the biochars.

    2014-08-01

    Alkali-soluble pectin, which has been extracted from Canna edulis Ker, was characterized by single sugar determination and atomic force microscopy (AFM). The results indicated that the amounts of four predominant sugars including arabinose (Ara), glucose (Glc), galactose (Gal) and galacturonic acid (GalA) significantly decreased during the process of mild acid hydrolysis. The decreasing rates of these four sugars followed a sequential order of Ara>Gal>Glc>GalA. The homogalacturonan (HG) chain present in pectin, and the quantity of branched material is greater than the sample containing the main neutral sugars. The results indicated that the neutral sugar and HG side chains are attached to pectin as part of the rhamnogalacturonan I (RGI) complex. Moreover, hydrolysis leads to the reduction of mean lengths of backbone and branch, as well as the number/weight-average molecular weight. Meanwhile, the amount of short chain fractions increased during hydrolysis. Furthermore, the decrease of the polymerization degree of alkali-soluble C. edulis pectin as a function of the hydrolysis time could be described by a first-order exponential decay function.

    A novel approach to synthesize silver nanoparticles (AgNPs) using leaf extract of Canna edulis Ker-Gawl. (CELE) under ambient conditions is reported here. The as-prepared AgNPs were analyzed by UV-visible spectroscopy, transmission emission microscopy, X-ray diffraction, Fourier transform-infra red spectroscopy, energy-dispersive analysis of X-ray spectroscopy, zeta potential, and dynamic light scattering. The AgNPs showed excellent antimicrobial activity against various pathogens, including bacteria and various fungi. The biocompatibility of the AgNPs was analyzed in the L929 cell line using NRU and MTT assays. Acridine orange/ethidium bromide staining was used to determine whether the AgNPs had necrotic or apoptotic effects on L929 cells. The concentration of AgNPs required for 50% inhibition of growth of mammalian cells is far more than that required for inhibition of pathogenic microorganisms. Thus, CELE is a candidate for eco-friendly, clean, cost-effective, and non-toxic synthesis of AgNPs.

  8. Loss of YABBY2-like gene expression may underlie the evolution of the laminar style in Canna and contribute to floral morphological diversity in the Zingiberales

    Directory of Open Access Journals (Sweden)

    Kelsie eMorioka

    2015-12-01

    Full Text Available The Zingiberales is an order of tropical monocots that exhibits diverse floral morphologies. The evolution of petaloid, laminar stamens, staminodes, and styles contributes to this diversity. The laminar style is a derived trait in the family Cannaceae and plays an important role in pollination as its surface is used for secondary pollen presentation. Previous work in the Zingiberales has implicated YABBY2-like genes, which function in promoting laminar outgrowth, in the evolution of stamen morphology. Here, we investigate the evolution and expression of Zingiberales YABBY2-like genes in order to understand the evolution of the laminar style in Canna. Phylogenetic analyses show that multiple duplication events have occurred in this gene lineage prior to the diversification of the Zingiberales. Reverse transcription-PCR in Canna, Costus, and Musa reveals differential expression across floral organs, taxa, and gene copies, and a role for YABBY2-like genes in the evolution of the laminar style is proposed. Selection tests indicate that almost all sites in conserved domains are under purifying selection, consistent with their functional relevance, and a motif unique to monocot YABBY2-like genes is identified. These results contribute to our understanding of the molecular mechanisms underlying the evolution of floral morphologies.

    Viscosity reduction and the effect of cell-wall degrading enzymes (CWDEs) were investigated using Canna edulis Ker. for bioethanol fermentation. The fermentation mash treated with CWDEs was much thinner (2.12 Pas) than the control mash (8.42 Pas), the fermentation efficiency was increased from 90.46% to 96.11%. HPLC analysis revealed that after treated with CWDEs, glucose and total sugar were increased by 28.07% and 7.60%, respectively. Changes in the starch granules were investigated by scanning electron microscopy (SEM), atomic force microscopy (AFM), and confocal laser scanning microscopy (CLSM). The results suggested that the reduction in viscosity was caused by changes in saccharide composition and physical changes of the starch granules. This present study is of significance that non-starch polysaccharides and starch can be simultaneously utilized for bioethanol production using roots and tubers as feedstock.

    In this study, we extracted lignin from Canna edulis ker residue. Its chemical structure, inhibitory activity on α-d-glucosidase, and kinetics as well as interaction mechanism were investigated by using spectrum analysis and docking simulation. The isolated lignin was composed by guaiacyl and syringal units, and exhibited stronger inhibition on α-d-glucosidase than acarbose with the half maximal inhibitory concentration at 5.3±0.3μM. It was a non-competitive inhibitior with Km and Ki values of 0.53±0.02mM and 0.92±0.12μM, respectively. It could quench the intrinsic fluorescence of α-d-glucosidase through a static quenching mode. The calculated values of enthalpy and entropy change were 20.8±2.5kJmol(-1) and 172.7±0.8Jmol(-1)K(-1), respectively. There was a single binding site on α-d-glucosidase for lignin, and the binding distance was 3.2nm. The molecular docking analysis exhibited that the hydrogen bonds, hydropholic interaction, and van der Waals forces were the main forces for lignin bind to α-d-glucosidase. This work provides a new insight into the interaction between the lignin and α-d-glucosidase, which might be beneficial to type 2 diabetes with the application of lignin in functional food and pharmacy fields.

    2002-04-01

    Surveys of visitor and grower perception of live potted plant quality were conducted in various locations in a large public display garden. Canna lily, Canna x generalis L.H.Bailey, was used to examine effects of defoliation by Japanese beetle, Popillia japonica Newman, on public perception. Chrysanthemums, Chrysanthemum x morifolium Ramat., were used to identify visitor and grower tolerance to flower distortion caused by western flower thrips, Frankliniella occidentalis (Pergande), on single and multiple flowered plants. On average, the maximum amount of defoliation or flower distortion tolerated by any respondent was low (< or = 10% for canna and < or = 25% for chrysanthemum). The level of acceptable injury was influenced by factors intrinsic to both the respondents and the plants themselves. Tolerance to injury was negatively associated with the risk aversion of the respondents. Visitors were less tolerant of injury on plants they considered for purchase than those that they would view at the garden. Similarly, grower tolerance was lower than that of visitors because producing substandard plants could put their professional reputation at risk. Factors that distracted visitor attention (e.g., presence of flowers and higher levels of background injury) increased their tolerance to plant injury. Visitors tolerated greater levels of flower distortion on multiple flowering chrysanthemum than on those with single flowers. We suggest that tolerance to insect pests can be increased by designing plantings that distract viewers from injured plant parts.

    Full Text Available Starch of ganyong is one of the sources of ethanol which is able to be produced by acid hydrolysis and fermentation process. It had high concentration of carbohydrate that is 80%, so it could produce glucose highly within acid hydrolysis process. The result showed that the optimal amount of reducing sugar had been produced by nitrate acid 7% (dextrose equivalent, DE = 28.4. Nevertheless, type and concentration of acid had no significantly correlation to reducing sugar yielded. The total amount of glucose had correlation to amount of ethanol, in fermentation process. The optimal amount of ethanol was yielded from 4.81% of glucose and it produced about 4.84% ethanol. The more amount of glucose was yielded the more ethanol was produced. Controlling pH every 12 hours did not affected to production of ethanol significantly.

    Pot-scale wetlands were used to investigate the role of plants in enhancing the performance of engineered bioremediation techniques like biostimulation, bioaugmentation, and phytoremediation collectively. Canna generalis plants were grown hydroponically in BTEX contaminated groundwater supplied in wetland mesocosms. To quantify the contaminant uptake by the plants, wetlands with and without shoot biomass along with unplanted gravel bed were used under controlled conditions. The residual concentration of the selected BTEX compound, toluene, in the rhizosphere water was measured over the entire period of the experiment along with the water lost by evapotranspiration. The rate of biodegradation in all wetland mesocosms fitted best with the first-order kinetics. The total removal time of the BTEX compound was found to be highest in the unplanted gravel bed mesocosm followed by wetlands without and with shoot biomass. The cumulative uptake of toluene in shoot biomass of the wetland plants initially increased rapidly and started to decrease subsequently till it reached a peak value. Continuity equations integrated with biodegradation and plant uptake sink terms were developed to simulate residual concentration of toluene in rhizospheric water for comparison with the measured data for entire period of the experiments. The results of this research can be used to frame in situ plant-assisted bioremediation techniques for hydrocarbon-contaminated soil-water resources.

    Full Text Available Modern scholars analyze the chronicles of the Indies as a set of accounts, reports, ways of narrating the lived experiences in the New World, which were tinged with providentialism, mesianism and other value judgments from their rhetoric structure and judeo- Christian pastoral. The Historia by Fernández de Oviedo (1478-1557 is a perfect example. Although the Historia contains various elements of style that are representative of a genre whose main quality has undoubtedly to do with historiography, it incorporates many allegorical and imaginative levels belonging to a literary textual formation. In this article I shall explore both the construction of a model of Christian hero, and its reverse, as literary figures in the elaboration of a imperialistic and colonial historiography.

    Autores recientes insisten en que las crónicas de Indias son un conjunto de narraciones, relatos, estilos de contar las experiencias vividas en el Nuevo Mundo, impregnadas de providencialismo, mesianismo y de otros juicios de valor procedentes de su formación retórica y de la pastoral judeocristiana. La Historia de Fernández de Oviedo es un ejemplo perfecto. Aunque la Historia contiene ciertos rasgos de estilo propios de un género cuyo carácter tiene que ver indudablemente con la historiografía, incorpora múltiples planos alegóricos e imaginativos pertenecientes a una formación textual literaria. En este artículo vamos a analizar la construcción de un modelo de héroe cristiano, y su reverso, como figuras literarias en la elaboración de una historiografía colonial e imperialista.

    Sediments are regarded as the ultimate sink of pentachlorophenol(PCP) in aquatic environment, and capabilities of seven species of aquatic macrophytes for remediating PCP contaminated sediment were investigated. Seven species of aquatic macrophytes could significantly accelerate the degradation of PCP in sediments. Among all, canna indica L., Acorus calamus L. and Iris tectorum Maxim. can be used as efficient alternative plants for remediation of PCP contaminated sediment, which attained 98%, 92% and 88% of PCP removal in sediments, respectively. PCP was detected only in root tissues and the uptake was closely related to the root lipid contents of seven plants. The presence of seven aquatic macrophytes significantly increased microbial populations and the activities of dehydrogenase compared with control sediments, indicating that rhizosphere microorganism played important role in the remediation process. In conclusion, seven species of aquatic macrophytes may act as promising tools for the PCP phytoremediation in aquatic environment, especially Canna indica L., Acorus calamus L. and Iris tectorum Maxim.

  6. Aquatic Plant/microbial Filters for Treating Septic Tank Effluent

    Wolverton, B. C.

    1988-01-01

    The use of natural biological processes for treating many types of wastewater have been developed by NASA at the John C. Stennis Space Center, NSTL, Mississippi, during the past 15 years. The simplest form of this technology involves the use of aquatic plant/marsh filters for treatment of septic tank effluent. Septic tank effluent from single home units can be treated to advanced secondary levels and beyond by using a 37.2 sq m (400 sq ft) surface area washed gravel filter. This filter is generally 0.3 m (1 ft) deep with a surface cover of approximately 0.15 m (6 in.) of gravel. The plants in this filter are usually aesthetic or ornamental such as calla lily (Zantedeschia aethiopica), canna lily (Canna flaccida), elephant ear (Colocasia esculenta), and water iris (Iris pseudacorus).

    This paper attempts toregard spatial relation transformationas an important process in map gener-alization. The spatial relation generali-zation can be divided into the compo-nents of abstraction: topology, dis-tance and orientation. The concept‘ spatial relation resolution' is intro-duced to describe the constraints ofrelative spatial relation. On the basisof nine intersection models, the cardi-nal direction models and the iso-dis-tance-relation models, this paper givesthree sorts of relation resolution repre-sentations for topological, distance andorientation relation, respectively. Twomapping implementations in map gen-eralization is discussed.

    Human papilomaviruses (HPVs) have been detected in cervical cancer cels and skin papiloma cels, which have a variety of types, including low-risk and high-risk types. HPV genome replication requires the host cel’s DNA synthesis machinery, and HPVs encode proteins that maintain diferentiated epithelial cels in a replication-competent state. HPV types are tissue-specific and generaly produce diferent types of le-sions, either benign or malignant. This review examines diferent HPV types and their associated diseases and presents therapeutic options for the treatment of HPV-positive diseases.

    This study evaluated the performance of soil and coal cinder used as substrate in vertical-flow constructed wetlands for removal of fluoride and arsenic. Two duplicate pilot-scale artificial wetlands were set up, planted respectively with cannas, calamus and no plant as blank, fed with a synthetic sewage solution. Laboratory (batch) incubation experiments were also carried out separately to ascertain the fluoride and arsenic adsorption capacity of the two materials (i.e. soil and coal cinder). The results showed that both soil and coal cinder had quite high fluoride and arsenic adsorption capacity. The wetlands were operated for two months. The concentrations of fluoride and arsenic in the effluent of the blank wetlands were obviously higher than in the other wetlands planted with cannas and calamus. Fluoride and arsenic accumulation in the wetlands body at the end of the operation period was in range of 14.07-37.24% and 32.43-90.04%, respectively, as compared with the unused media.

    Starches were isolated from rhizomes of Curcuma longa, Canna edulis and Canna indica and bulbs of Lilium lancifolium, and showed a B-type X-ray diffraction pattern. Their physicochemical properties were investigated and compared. These starches showed significantly different granule morphologies and sizes, but all had eccentric hila. The C. longa starch had the lowest content of amylopectin short branch-chain and branching degree and the highest content of amylopectin long branch-chain, and the L. lancifolium starch the highest content of amylopectin short branch-chain and branching degree and the lowest content of amylopectin long branch-chain among the four starches. The L. lancifolium starch had the lowest resistance to gelatinization, and showed the lowest pasting peak, hot and final viscosities, and the C. longa starch had the highest resistance to gelatinization, and showed the highest pasting hot, final and setback viscosities and the lowest pasting breakdown viscosity. The C. longa and L. lancifolium starches possessed very high and low resistance to hydrolysis and digestion, respectively. The above physicochemical properties would be useful for the applications of B-type starches in food and nonfood industries.

    The present paper cherishes its purpose to study the purifying effects of artificial wetland with different vegetation systems on domestic leftover sewage. So far as we know, there has been exiting quite a large number of studies in this way that claim to have discovered some plants can be used for this purpose. Many kinds of plants in wetland, so far as we know, can provide a substrate ( roots, stems, and leaves) upon which microorganisms can grow as they break down some organic materials. The plants should have the ability of enduring pollution, good effect of decontamination, developed root system and strong resistance to diseases and insect-attacking, great economic value. For example, Canna India has been widely used in such artificial wetlands as a kind of pollution-resistant plant. However, Pennisetum purpureum is still under experiments. The purification effect of Pennisetum purpureum and Canna india on such sewage in the surface-flowing artificial wetland was studied. For this purpose, we have done testing and observation to study water quality of the flowing water, and purifying effect of TN and TP by using the above-said plant systems under the conditions of different temperatures are discussed. Our experiments are of practical significance in the sense of scientific research, data assistance and theoretical reasoning for Pennisetum purpureum , which can help to improve the wetland water environment quality and repair the sewage body. The results of our study indicate that both Pennisetum purpureum and Canna india enjoy a good purifying effect on the domestic sewage with a nice removal efficiency of TP and TN. Statistically, the average removal rate of COD is 58.38% and 49.49%, TN can be as high as 76.77% and 66.49%, and TP can be as high as 82.99% and 87.99%., respectively. Moreover, the sewage purification efficiency of the two plants in the artificial wetland has no direct correlation with the change of temperature, because the purification efficiency

    Five organic esters with different curing speeds: propylene carbonate (i.e. high-speed ester A); 1, 4-butyrolactone; glycerol triacetate (i.e. medium-speed ester B); glycerol diacetate; dibasic ester (DBE) (i.e. low-speed ester C), were chosen to react with alkaline phenolic resin to analyze the application conditions of ester cured alkaline phenolic resin. The relationships between the curing performances of the resin (including pH value, gel pH value, gel time of resin solution, heat release rate of the curing reaction and tensile strength of the resin sand) and the amount of added organic ester and curing temperature were investigated. The results indicated the folowing: (1) The optimal added amount of organic ester should be 25wt.%-30wt.% of alkaline phenolic resin and it must be above 20wt.%-50 wt.% of the organic ester hydrolysis amount. (2) High-speed ester A (propylene carbonate) has a higher curing speed than 1, 4-butyrolactone, and they were both used as high-speed esters. Glycerol diacetate is not a high-speed ester in alkaline phenolic resin although it was used as a high-speed ester in ester cured sodium silicate sand; glycerol diacetate and glycerol triacetate can be used as medium-speed esters in alkaline phenolic resin. (3) High-speed ester A, medium-speed ester B (glycerol triacetate) and low-speed ester C (dibasic ester, i.e., DBE) should be used below 15 ºC, 35 ºC and 50 ºC, respectively. High-speed ester A or low-speed ester C should not be used alone but mixed with medium-speed ester B to improve the strength of the resin sand. (4) There should be a suitable solid content (generaly 45wt.%-65wt.% of resin), alkali content (generaly 10wt.%-15wt.% of resin) and viscosity of alkaline phenolic resin (generaly 50-300 mPa·s) in the preparation of alkaline phenolic resin. Finaly, the technique conditions of alkaline phenolic resin preparation and the application principles of organic ester were discussed.

  6. First-principle variational formulation of polarization effects in geometrical optics

    CERN Document Server

    Ruiz, D E

    2015-01-01

    The propagation of electromagnetic waves in isotropic dielectric media with local dispersion is studied under the assumption of small but nonvanishing $\\lambda/l$, where $\\lambda$ is the wavelength, and $l$ is the characteristic inhomogeneity scale. It is commonly known that, due to nonzero $\\lambda/l$, such waves can experience polarization-driven bending of ray trajectories and polarization dynamics that can be interpreted as the precession of the wave "spin". The present work reports how Lagrangians describing these effects can be deduced, rather than guessed, within a strictly classical theory. In addition to the commonly known ray Lagrangian featuring the Berry connection, a simple alternative Lagrangian is proposed that naturally has a canonical form. The presented theory captures not only eigenray dynamics but also the dynamics of continuous wave fields and rays with mixed polarization, or "entangled" waves. The calculation assumes stationary lossless media with isotropic local dispersion, but generali...

    2016-01-01

    To be close to the practical flight process and in-crease the precision of optimal trajectory, a six-degree-of- freedom (6-DOF) trajectory is optimized for the reusable launch vehicle (RLV) using the Gauss pseudospectral method (GPM). Different from the traditional trajectory optimization problem which generaly considers the RLV as a point mass, the coupling between translational dynamics and rotational dynamics is taken into account. An optimization problem is formulated to minimize a performance index subject to 6-DOF equations of motion, including translational and rotational dynamics. A two-step optimal strategy is then introduced to reduce the large calculations caused by multiple variables and convergence confinement in 6-DOF trajectory optimization. The simulation results demonstrate that the 6-DOF trajectory optimal strategy for RLV is feasible.

    Full Text Available Semantic Wiki consentono, tramite un linguaggio comprensibile agli elaboratori e formalmente definito, l’annotazione semantica dei contenuti delle pagine Wiki e la rappresentazione esplicita delle relazioni di significato tra essi presenti. Essi offrono la possibilità di sfruttare sia i vantaggi delle tecnologie basate su ontologie sia i meccanismi collaborativi propri dei Wiki. L’articolo descrive un progetto, denominato Semantic WikiSUN, avviato per indagare le prospettive didattiche di tali sistemi. Esso è basato su un quadro teorico complesso che integra evidenze neurocognitive, teorie dell’apprendimento e modelli costruttivisti-sociali della conoscenza. Obiettivo del contributo è, sulla base della esperienza intrapresa, discutere potenzialità e criticità didattiche dei Semantic Wiki, estendendo talvolta la riflessione a considerazioni più generali sui processi di apprendimento mediati da tecnologie semantiche.

    Full Text Available La città è ampiamente leggibile e la storia ci racconta il suo processo costruttivo  con le sue ricche narrazioni analitiche e conoscitive. Nella non-città i contenuti e le forme si dilatano, si spalmano, si nascondono, appaiono estemporaneamente, cambiano i contesti di riferimento, cambiano le proprie forme generali e specifiche. La continuità spaziale fra città e non-città esiste certamente dal punto di vista della forma architettonica e della cultura storica, ma bisogna fare grande attenzione a discernere con precisione i sicuri e diversi modelli tipologici e funzionali di riferimento. Esistono certamente tramature comuni, ma esistono filamenti strutturali assolutamente autonomi, specifici e tipici in un dato territorio della non-città. Il vero problema, purtroppo, è la difficoltà/capacità di poterli individuare e di re-introdurli negli atti di pianificazione e nelle politiche di governo del territorio.

    Full Text Available A new quantum gravity experiment is reported with the data confirming the generali- sation of the Schrödinger equation to include the interaction of the wave function with dynamical space. Dynamical space turbulence, via this interaction process, raises and lowers the energy of the electron wave function, which is detected by observing conse- quent variations in the electron quantum barrier tunnelling rate in reverse-biased Zener diodes. This process has previously been reported and enabled the measurement of the speed of the dynamical space flow, which is consistent with numerous other detection experiments. The interaction process is dependent on the angle between the dynamical space flow velocity and the direction of the electron flow in the diode, and this depen- dence is experimentally demonstrated. This interaction process explains gravity as an emergent quantum process, so unifying quantum phenomena and gravity. Gravitational waves are easily detected.

    Full Text Available In uno scritto recente ho sostenuto la tesi che la politica ottimale per il Mezzogiorno non è il laissez faire, né l’intervento diretto dello stato nell’economia, ma un intervento pubblico, anche “massiccio”, realizzato mediante leggi generali e astratte, che per loro natura sono di tipo non discrezionale.La necessità di un intervento generalizzato a favore di una zona meno sviluppata si giustifica con l’esistenza delle “diseconomie esterne”, che frenano lo sviluppo di tutte le imprese che operano in quella zona.

    Full Text Available A partire da una rilettura di opere, come Die Protestantische Ethik und der Geist der Kapitalismus e Die Boersenequete, l'articolo mostra che – in linea con quanto Max Weber aveva descritto – l'assenza di regole generali condivise e di controlli pubblici mette in crisi le fondamenta del sistema finanziario. La privatizzazione neoliberista degli organi di controllo della finanza e la creazione di oscuri strumenti finanziari hanno contribuito alla regressione dell'organizzazione giuridica dello Stato, mettendo a serio rischio il principio di calcolabilità razionale che per secoli ha costituito il fondamento della teoria economica. In conclusione, Weber contribuisce a cogliere uno dei nodi fondamentali della crisi americana contemporanea: l'erosione dell’autorità indipendente posta a tutela dell’integrità del sistema.

    ABSTRACT A natural epidemic of Fusarium wilt on coca (Erythroxylum coca) in Peru prompted the suggestion of possibly using the pathogen Fusarium oxysporum f. sp. erythroxyli as a mycoherbicide against this narcotic plant. During field trials conducted in Kauai, HI, to test the pathogenicity of the coca wilt pathogen, ants were observed removing formulations from test plots. While removal of formulations by ants was considered detrimental with respect to conducting field tests, ant removal was considered potentially beneficial in disseminating the mycoherbicide. Thus, research was initiated to assess the ability of formulation additives to alter the preference of ants for the formulated mycoherbicide. In Hawaii, preference of indigenous ants for removing formulations was tested using three different food bases (rice, rice plus canola oil, and wheat flour [gluten]). Similar tests were conducted at Beltsville, MD, using F. oxysporum f. sp. melonis, in which the formulation based on wheat flour was replaced by a formulation based on canola meal. Formulations based on wheat were preferred by ants in both locations; up to 90% of the wheat plus rice flour granules (C-6) and the wheat gluten plus kaolin granules (pesta) were removed within 24 h, while only 20% of those containing rice without oils were taken. However, when either canola, sunflower (Maryland only), or olive oil was added to the rice formulation, up to 90% of the granules were taken. The formulation based on canola meal was less attractive to ants, as only 65% of the granules were removed within a period of 24 h. Ants showed no preference with respect to presence or absence of fungal biomass. To alter the attractiveness of the C-6 formulation to ants, C-6 was amended with three natural products. Canna and tansy leaves were added to C-6 at a ratio of 1:5 (wt/wt), while chili powder was added at 1:25 or 1:2.5 (wt/wt). Canna, tansy, and the higher rate of chili powder significantly reduced the number of C-6

  3. An Experiment About Parallel Circuit And The Lorentz Forces On Wires

    CERN Document Server

    Li, Audrey Yueru

    2015-01-01

    Parallel circuit and the Lorentz forces on current carrying wires are important concepts in introductory physics courses. Here we describe an experiment that illustrates these two concepts. We mount a circuit with multiple grounding points onto a torsion balance. We show that the grounding points create parallel return paths for the supply current. When the topology or the shapes of the return paths are altered, the Lorentz forces exerted by the currents in the return paths within a magnetic field change accordingly, which in turn cause changes in the rotary displacement of the torsion balance. This experiment is simple and can be easily reproduced in a teaching laboratory. What makes it interesting to students is that recently two research teams have attempted to detect thrusts from microwave driven asymmetrical resonance cavities (EmDrive or Cannae Drive), and the phenomenon observable in this experiment provides an alternative explanation to the thrusts they detected.

    In recent years, rural decentralized sewage treatment have gained widespread attention. Although wastewater treatment facility has been developed for rural areas, most rural population are left without adequate wastewater treatment systems. In the present study, the performance of iron-carbon coupling constructed wetland system (ICCWS) and constructed wetland system (CWS) receiving synthetic domestic wastewater were compared in side-by-side trials. Studies have found that CWS filled with spherical iron-carbon packing showed better treatment efficiency than normal CWS. When the HRT is 3 days, the ICCWS have 95.8% COD and 96.6% PO4 3- removal rate, higher than 67.0% COD and 74.3% PO4 3- removal rate in CWS respectively. The use of ICCWS planted with canna and cattail proved to be efficient technology for the removal of rural wastewater pollutants.

    Nutrient removal behaviors of four aquatic plant treatment systems (Oenanthe javanica, Iris pseudacorus L., Canna lily, and Potamogeton crispus) were systematically examined and compared. The kinetics of nutrient uptake were conducted with the standard depletion method. All four aquatic species exhibited a strong preference of ammonium nitrogen (NH4(+)-N) over nitrate nitrogen (NO3(-)-N) and nitrite nitrogen (NO2(-)-N). Main pathways of nutrient removal in the aquatic plant treatment system were examined in details. It was estimated that direct assimilation by plants accounted for 28.2-34.5% of N reduction and 25.2-33.4% of P reduction while substrate absorption accounted for 7.2-25.5% of N reduction and 7.3-25.0% of P reduction. The activity of urease and phosphatase in the substrates could indicate the aquatic plant treatment system's capability for reducing TN and soluble P load.

    Full Text Available Scarabaeidae defoliators are considered of great importance in Brazil because they seriously damage the leaf system of several plant species. The objective of this study was to report the occurrence of the defoliating beetle Bolax campicola Machatschke, 1974 (Coleoptera: Scarabaeidae attacking ornamental plants in the urban area of municipality of Forestal, Minas Gerais State, Brazil. The initial attack was observed on the ornamental palm species Dypsis lutescens (Arecaceae whose leaves were completely consumed, and then these insects began to feed on Canna indica (Cannaceae, another ornamental species, which was found near to the first. However, in the same location newly planted fruit tree seedlings of Plinia trunciflora (Myrtaceae, Averrhoa carambola (Oxalidaceae and Malpighia emarginata (Malpighiaceae were attacked and completely defoliated. This report of damage to plants in urban areas by B. flavolineatus demonstrates the need for studies on the behavior and feeding preference of these insects, and even their ability to adapt to different host plants.

    Grindstones from Eva 2 and St. John, two of the earliest sites in northeastern South America and the southern Caribbean respectively, were subjected to starch grain analysis. Results of this study revealed that these stone artifacts were utilized to process a variety of cultivars such as maize (Zea mays), sweet potato (Ipomoea batatas), chili pepper (Capsicum spp.), achira (Canna spp.), legumes (Fabaceae), and yams (Dioscoreaceae), coupled with wild resources, most notably marunguey (Zamia spp.). Radiocarbon dates indicate that the use of plants identified at these two sites were much older than previously considered, going back to at least 7790 cal. BP at St. John and 5990 cal. BP at Eva 2. This new evidence showcases the importance of the Caribbean basin as an arena for early phytocultural dispersals. It also focuses attention on the role of navigation as a mechanism for crop diffusion in the Neotropics.

    The herbicide 3-amino-1, 2, 4-triazole induces complete chlorosis without any morphogenetic effect on Canna edulis leaves. Comparative analyses of the mineral and biochemical composition and also of the physiological properties of normal and bleached leaf cells establish a high specificity of this herbicide for inhibition of formation of chloroplast membranes. The synthesis of membrane lipids and chloroplastic terpenoid derivatives were specifically inhibited. This compound was found to inhibit photosynthetic O(2) evolution and (14)CO(2) fixation at the whole cell level and ferricyanide reduction in isolated chloroplasts immediately after its application. This inhibition was reversible with the addition of a number of unrelated compounds shown to nullify its herbicidal effect.The mechanism of action of this compound in specifically blocking the development of chloroplast membranes in discussed in terms of its primary action on photosynthetic carbon fixation.

    Ethanol production from Canna edulis Ker was successfully carried out by solid state simultaneous saccharification and fermentation. The enzymatic hydrolysis conditions of C. edulis were optimized by Plackett-Burman design. The effect of inert carrier (corncob and rice bran) on ethanol fermentation and the kinetics of solid state simultaneous saccharification and fermentation was investigated. It was found that C. edulis was an alternative substrate for ethanol production, 10.1% (v/v) of ethanol concentration can attained when 40 g corncob and 10 g rice bran per 100 g C. edulis powder were added for ethanol fermentation. No shortage of fermentable sugars was observed during solid state simultaneous saccharification and fermentation. There was no wastewater produced in the process of ethanol production from C. edulis with solid state simultaneous saccharification and fermentation and the ethanol yield of more than 0.28 tonne per one tonne feedstock was achieved. This is first report for ethanol production from C. edulis powder. (author)

    Animals can discriminate among many different types of foods. This discrimination process involves multiple sensory systems, but the sense of taste is known to play a central role. We asked how the taste system contributes to the discrimination of different "bitter" taste stimuli in Manduca sexta caterpillars. This insect has approximately eight bilateral pairs of taste cells that respond selectively to bitter taste stimuli. Each bilateral pair of bitter-sensitive taste cells has a different molecular receptive range (MRR); some of these taste cells also contain two signaling pathways with distinctive MRRs and temporal patterns of spiking. To test for discrimination, we habituated the caterpillar's taste-mediated aversive response to one bitter taste stimulus (salicin) and then asked whether this habituation phenomenon generalized to four other bitter taste stimuli (caffeine, aristolochic acid, Grindelia extract, and Canna extract). We inferred that the two compounds were discriminable if the habituation phenomenon failed to generalize (e.g., from salicin to aristolochic acid). We found that M. sexta could discriminate between salicin and those bitter taste stimuli that activate (1) different populations of bitter-sensitive taste cells (Grindelia extract and Canna extract) or (2) different signaling pathways within the same bitter-sensitive taste cell (aristolochic acid). M. sexta could not discriminate between salicin and a bitter taste stimulus that activates the same signaling pathway within the same bitter-sensitive taste cell (caffeine). We propose that the heterogeneous population of bitter-sensitive taste cells and signaling pathways within this insect facilitates the discrimination of bitter taste stimuli.

    Full Text Available This study was conducted to quantify emissions of greenhouse gases (GHGs, methane (CH4 and Nitrous Oxide (N2, from free water surface constructed wetlands used for domestic wastewater treatment. All constructed wetlands were monoculture and each plot was planted with Phragmites sp., Cyperus sp., or Canna sp. The average CH4 and N2 O emissions were in the range of 5.9-11.2 and 0.9-1.8 g/m2/h, respectively. Seasonal fluctuations of CH4 and N2 O emissions were observed. The highest fluxes of both GHGs occurred during hot rainy season (July-October followed by summer and the lowest found in cool season. The mean of CH4 and N2O emissions from different plants species were significantly different (p<0.05. Average CH4 emissions from constructed wetlands planted with Phragmites sp., Cyperus sp. and Cannasp. were 11.2, 6.0 and 5.9 mg/m2/h, respectively, while mean N2O emissions were 0.9, 1.0 and 1.8 mg/m2/h, respectively. Calculated of Global Warming Potential (GWP found that GWP of CH4 and N2O flux from constructed wetlands planted with Cyperus sp., was the highest (669 mg CO2 equivalent/m2/h, followed by Phragmite sp., (524 mg CO2 equivalent/m2/h and Cannasp., (434 mg CO2 equivalent/mm2/h, respectively. These results suggested that municipal wastewater treatment by constructed wetlands planted with Canna sp. and Phragmite sp., had potential of lower GHGs emissions into the atmosphere and Phragmite sp., provided the highest removal rate of Biochemical Oxygen Demand (BOD and Chemical Oxygen Demand (COD.

    The objective of this study was to investigate the relationship between Cd{sup 2+}/NH{sub 4}{sup +} sorption and physicochemical properties of biochars produced from different wetland plants. Biochars from six species of wetland plants (i.e., Canna indica, Pennisetum purpureum Schum, Thalia dealbata, Zizania caduciflora, Phragmites australis and Vetiveria zizanioides) were obtained at 500 °C and characterized, and their sorption for ammonium and cadmium was determined. There were significant differences in elemental composition, functional groups and specific surface area among the biochars derived from different wetland plant species. Sorption of ammonium and cadmium on the biochars could be described by a pseudo second order kinetic model, and the simple Langmuir model fits the isotherm data better than the Freundlich or Temkin model. The C. indica derived biochar had the largest sorption capacity for NH{sub 4}{sup +} and Cd{sup 2+}, with a maximum sorption of 13.35 and 125.8 mg g{sup −1}, respectively. P. purpureum Schum derived biochar had a similar maximum sorption (119.3 mg g{sup −1}) for Cd{sup 2+}. Ammonium sorption was mainly controlled by cation exchange, surface complexation with oxygen-containing functional groups and the formation of magnesium ammonium phosphate compounds, whereas for Cd{sup 2+} sorption, the formation of cadmium phosphate precipitates, cation exchange and binding to oxygen-containing groups were the major possible mechanisms. In addition, the sorption of ammonium and cadmium was not affected by surface area and microporosity of the biochars. - Highlights: • Biochars varied in physicochemical properties and adsorption capacity. • Canna indica derived biochar has a high sorption capacity for Cd{sup 2+}. • NH{sub 4}{sup +} and Cd{sup 2+} sorption on biochars fits a pseudo second order and Langmuir model. • Sorption mechanism is related to complexation, cation exchange and precipitation.

    Riportiamo la nostra esperienza retrospettiva sulle occlusioni intestinali da cancro colorettale. Negli ultimi 6 anni, abbiamo operato 238 pazienti affetti da cancro colorettale. I tumori complicati sono stati 136 (56%), 115 dei quali stenosanti (86%) e 19 perforati (14%). In 23 pazienti (20%) il tumore stenosante del colon era a destra ed in 92 (80%) a sinistra. Questi ultimi sono stati suddivisi retrospettivamente in 4 gruppi, in relazione all’intervento chirurgico eseguito: 18 (19%) colostomie decompressive; 32 (35%) procedure in due stadi: 25 operazioni di Hartmann e 7 colectomie totali con ileostomia terminale; 7 (8%) procedure in uno stadio, con ileostomia di protezione: 4 colectomie totali e 3 resezioni del colon con wash-out; 35 (38%) procedure in uno stadio con anastomosi primaria + wash-out o milking. I decessi sono stati 8/115, con un tasso di mortalità operatoria globale del 7%. Il tasso di fistola anastomotica è stato del 10%, riguardando 6/58 pazienti con anastomosi, 5 dei quali hanno richiesto un reintervento chirurgico. Complessivamente, circa 2/3 dei decessi perioperatori sono avvenuti per complicanze generali ed un terzo per deiscenza dell’anastomosi. L’occlusione intestinale da cancro colorettale è associata ad un’elevata mortalità operatoria ed una prognosi peggiore, in termini di recidiva e di sopravvivenza. La colostomia decompressiva può essere considerata come un’opzione valida solo nella malattia avanzata o nel paziente in condizioni generali scadute. La resezione anastomosi primaria rappresenta il gold-standard in pazienti selezionati con un basso rischio anestesiologico, sia sotto forma di resezione tipica con washout, sia come colectomia subtotale. Una colostomia o ileostomia temporanea di protezione può essere proposta per i pazienti con un rischio anestesiologico intermedio. Nei casi ad alto rischio o in avanzato stato occlusivo, oppure in presenza di simultanea perforazione del colon o di malattia metastatica o

    In the recently published 2013 revision of the guidelines of urticaria, chronic urticaria (CU) gathers chronic spontaneous urticaria (CSU) and inducible urticaria (IU), and excludes pseudourticarial rashes with more than 24h-lasting rash or more than 72h-lasting angiœdema. Activity and psychosocial impact of the disease must be measured with validated scores such as Urticaria and Angioedema Activity Scores, Urticaria Control Test, CU-Q2OL, AE-QOL. Although an allergic cause is generaly absent in CU, pathomecanisms remain elusive even since the well-known role of mast cell degranulation and the presence of autoantibodies anti-FcRεI or anti-IgE. Coagulation pathways may be involved, at least as an amplifying phenomenon. Mean duration of CU is 1 to 4 years, but many patients still have symptoms after 10 years, some predictive factors being known as severity, angioedema, a positive autologous serum test, inducible urticaria. Recommended routine diagnosic tests are validated provocation tests for IU (and cryoproteins for cold urticaria), blood cell count and CRP for CSU, since a thorough history and a normal detailed physical examination should avoid unnecessary tests. Management of CU has been improved by the off-label use of increased dosages of second generation anti- H1 antihistamines, but a subsequent therapeutic intensification may be necessary in some cases. Educational program may prevent this intensification. Independent studies evaluating available molecules are needed, along with more fundamental research studies.

    Full Text Available The research aims to establish the main characteristics of subjects prone to compulsive overeating (experimental group, EG, and the differences between them and the girls who are not prone to any kind of eating disorders (control group, CG. The results of the research are in accordance with the expectations. Girls from the EG exhibit personality characteristics which are signifficantly different from the girls in the CG. These characteristics may be either possible predispositions for development of overeating, or they may already be the consequences of the girls' struggles with overeating and their perception of being overweight. The responses given by the girls from the EG confirm the generaly accepted characteristics of overeating individuals. It can be said that the girls from the ES show the pre-clinical picture of overeating, while some of them have already developed the clinical picture. The results of the research strongly support the view that overeating must be defined as a form of eating disorder just as important as anorexia and bulimia nervosa.

    Motor neuron hyperexcitability (MNH) indicates a disorder characterized by an ectopic motor nerve discharge on electromyogram (EMG). Here, we present a series of three cases of subacute MNH with mercury poisoning. The first case showed hyperhidrosis, insomnia, generalied myokymia, cramps, tremor, weight loss, and myokymic and neuromyotonic discharges, followed by encephalopathy with confusion, hallucinations, and memory decrease. The second case was similar to the former but without encephalopathic features. The third case showed widespread fasciculation, fatigue, insomnia, weight loss, and autonomic dysfunction, including constipation, micturition difficulty, and impotence, with multiple fibrillation, unstable fasciculation, widened motor neuron potential, and an incremental response at high-rate stimulation in repetitive nerve stimulation. Based on the symptoms, the three cases were diagnosed as Morvan's syndrome, Isaacs' syndrome, and Lambert-Eaton myasthenic syndrome with ALS-like syndrome, respectively. Mercury poisoning in the three cases was confirmed by analysis of blood and urine samples. All cases recovered several months after chelation therapy and were in good condition at follow-up. Very few cases of MNH linked with mercury exposure have been reported in the literature. The mechanism of mercury-induced MNH may be associated with ion channel dysfunction.

    RIASSUNTO. Il costrutto della "Food Addiction" (FA) è stato introdotto negli ultimi anni per meglio comprendere i pattern alimentari disfunzionali osservati nei pazienti obesi e in sovrappeso e nei pazienti con disturbi del comportamento alimentare (DCA). Nonostante i numerosi parallelismi tra la dipendenza da sostanze e la FA, non c'è ancora accordo nel considerare la FA come un indipendente DCA né un concetto utile. L'obiettivo della presente rassegna è stato quello di riassumere i dati disponibili al fine di aumentare le conoscenze su: 1) definizione, misurazione e caratteristiche generali della FA; 2) prevalenza della FA in campioni clinici e non clinici. I dati disponibili suggeriscono che la FA sia un costrutto transnosografico presente in tutti i DCA, con una prevalenza più elevata nella bulimia nervosa. Nonostante il dibattito sull'autonomia della FA come DCA rimanga aperto, gli studi riportati suggeriscono che la comorbilità tra FA e DCA sia associata con peggiori outcome clinici, giustificando di conseguenza l'assessment e il trattamento della FA.

In un soggiorno estivo sul Monte Amiata, in Toscana, la giovane notò un arrossamento della pelle al fianco sinistro del corpo. Non osservò presenza della zecca nella zona di presumibile inoculo, da cui si sviluppò un eritema migrante (EM ad andamento centrifugo, fino a raggiungere un diametro di circa 10 centimetri. Nei giorni successivi e durante il follow up non sono mai comparsi sintomi collaterali generali riferibili ad astenia, febbricola, artralgie, malessere, né a carico di organi bersaglio. Dopo circa due settimane, persistendo l’EM, sono stati eseguiti esami sierologici specifici per Borrelia burgdorferi. Al riscontro positivo dei test ELISA e western-blot IgG e IgM, il clnico ha prescritto terapia antibiotica a base di Amoxicillina 2g/die per 20 giorni.Dopo 8-10 giorni di terapia è avvenuta la scomparsa completa dell’eritema. Viene mostrato l’andamento dei test sierologici al momento della diagnosi e durante il follow up, per un periodo di circa cinque mesi.

    L’autotrapianto d’isole pancreatiche (IAT) è una procedura ben nota che consente di migliorare il controllo glicemico dopo una pancreasectomia totale (o completamento di pancreasectomia dopo duodenocefalopancreasectomia) rispetto alla sola terapia insulinica. In questo lavoro presentiamo la nostra esperienza nel campo dell’ IAT riportando il caso clinico di una donna di sessanta anni, sottoposta a completamento di pancreasectomia per episodi ricorrenti di acuzie in un quadro di pancreatite cronica. Il trattamento IAT è stato somministrato mediante iniezione trans-epatica intra-portale. Il recupero post-procedurale è stato ottimale, fatta eccezione per un’infezione di ferita che ha richiesto un trattamento con tecnologia a pressione negativa. La paziente è stata dimessa in ventisettesima giornata postoperatoria, in buone condizioni generali, dopo regolare ripresa dell’alimentazione e della canalizzazione. I dati presenti in letteratura dimostrano che la IAT è una procedura sicura, garantendo nel lungo periodo un vantaggio rispetto alla terapia insulinica in termini di rapporto costo-beneficio. Riguardo alla procedura chirurgica, è qui utile ricordare che la mortalità a 30 giorni dopo pancreasectomia totale associata a IAT è del 5%, ed è pertanto sovrapponibile ai risultati della pancreasectomia totale senza IAT. Riportando questa esperienza intendiamo contribuire alla crescita della casistica chirurgica attuale in questo campo, proponendo nel futuro un più ampio sviluppo e una più estesa applicazione di tale approccio.

    2013-04-01

    Full Text Available Domestic work in Argentina-as in Latin America in general-is one of the main sources of employment for low-income women, as well as one of the most unprotected types of occupation. On one hand, the regulation of this type of work is based on a special regime that implies substantially restricted rights when compared to those of the general legislation for salaried workers. On the other hand, despite the restricted rights of this occupation, employers' low levels of compliance are alarming. In this context, any attempt to improve these workers' situation requires measures aimed to change employers' behavior. Therefore, it is necessary to expand existing knowledge regarding the perceptions and conduct of those who hire these services. This exploratory piece of work is centered on the point of view of female employers -usually the ones responsible for the daily management of this type of work. The purpose is to look in depth at the discourse and practices related to this kind of work as an occupation, its workers as employees as well as this sector's rights and labor conditions.

    Full Text Available La poliedricità e la fertilità scientifica del fenomeno sportivo ormai è cosa nota. Anche in Italia, negli ultimi anni, sono stati sviluppati numerosi studi sullo sport. A tal proposito risulta rilevante l’attività di ricerca svolta nell’Università degli Studi di Teramo dal così definito “laboratorio atriano” . Vale a dire il centro di studi sito nella sede distaccata dell’Ateneo teramano della città di Atri. All’interno di tale “laboratorio”, fin dall’inizio delle sue attività, la riflessione filosofica intorno allo sport si è andata ritagliando un significativo spazio. Non sono, tuttavia, da negare le problematicità riscontrate nel far emergere un tale tentativo speculativo. Le difficoltà possono essere rintracciate nell’impostazione metodologica scelta dalle più generali “scienze dello sport”. In particolare, ad esempio, quando queste si sono trovate a rispondere circa la “vera natura” dello fenomeno sportivo.

    Full Text Available Una parte cospicua dell’opera scientifica di Mitja Skubic si può ritenere collocata più o meno direttamente in campi di studio aventi a che fare con la variazione. Una buona cinquantina dei più di 220 titoli di Skubic riportati nella bibliografia curata da Marjeta Prelesnik-Drozg in linguistica XLVIII (2008, 11–31, verte infatti sullo studio di fenomeni in specifiche varietà di lingua (il toscano parlato, la lingua di Goldoni, varie parlate venete, friulano e sloveno di Gorizia, e via discorrendo o su casi di interferenza e contatto nell’area italo-slovena, dove è per lo più evidente una dimensione variazionista. Vorrei quindi offrire al festeggiato in questa sede alcune riflessioni generali sulla questione della variazione linguistica che spero gli giungano gradite. Un tratto evidente nella linguistica anche teorica (o nelle diverse anime della linguistica1 degli ultimi decenni è infatti il progressivo aumento di interesse verso la variazione. Un problema sempre ritornante in tale contesto è quello del posto e del ruolo eventuale che la variazione possa o debba avere nella teoria lingui- stica. Riprendo quindi in queste pagine, con qualche sintetica argomentazione, una questione che, molto dibattuta negli anni Settanta in concomitanza con la fondazio- ne e lo sviluppo della linguistica variazionista di William Labov,2 è emersa solo spo- radicamente negli anni Ottanta e Novanta, ed è divenuta, su altre basi, di nuovo molto attuale all’inizio del Terzo Millennio.

    2009-01-01

    In this paper we prove some new Stone-type duality theorems for some subcategories of the category $\\ZLC$ of locally compact zero-dimensional Hausdorff spaces and continuous maps. These theorems are new even in the compact case. They concern the cofull subcategories $\\SkeZLC$, $\\QPZLC$, $\\OZLC$ and $\\OPZLC$ of the category $\\ZLC$ determined, respectively, by the skeletal maps, by the quasi-open perfect maps, by the open maps and by the open perfect maps. In this way, the zero-dimensional analogues of Fedorchuk Duality Theorem and its generalization are obtained. Further, we characterize the injective and surjective morphisms of the category $\\HLC$ of locally compact Hausdorff spaces and continuous maps, as well as of the category $\\ZLC$, and of some their subcategories, by means of some properties of their dual morphisms. This generalizes some well-known results of M. Stone and de Vries. An analogous problem is investigated for the homeomorphic embeddings, dense embeddings, LCA-embeddings etc., and a generali...

    2010-11-01

    Traveling-wave solutions are discovered in plane Couette flow. They are obtained when the so-called steady hairpin vortex state found recently by Gibson [J. Fluid Mech. 638, 243 (2009)] and Itano and Generalis [Phys. Rev. Lett. 102, 114501 (2009)] is continued to sliding Couette flow geometry between two concentric cylinders by using the radius ratio as a homotopy parameter. It turns out that in the plane Couette flow geometry two traveling waves having the phase velocities with opposite signs are associated with their appearance from the steady hairpin vortex state, where the amplitude of the phase velocities increases gradually from zero as the Reynolds number is increased. The solutions obviously inherit the streaky structure of the hairpin vortex state, but shape preserving flow patterns propagate in the streamwise direction. Other striking features of the solution are asymmetric mean flow profiles and strong quasistreamwise vortices which occupy the vicinity of only the top or bottom moving boundary, depending on the sign of the phase velocity. Furthermore, we find that the pitchfork bifurcation associated with the appearance of the solution becomes imperfect when the flow is perturbed by a Poiseuille flow component.

    2015-12-01

    Full Text Available Parto da una domanda che apre la strada per una breve riflessione su un problema che, da anni, mi interroga, quello dell’appartenenza nelle associazioni psicoanalitiche. Nei suoi termini generali, il quesito è abbastanza semplice: di cosa fa esperienza un individuo nel corso della sua analisi? In primo luogo di quello che Freud sostiene, e cioè che l’Io non è padrone in casa sua. Il sintomo che conduce l’analizzante a chiedere una cura ne è la prova più evidente; in secondo luogo del fatto che quest’area di non padronanza riporta il soggetto alla sua dipendenza dalle richieste inconsce dei familiari e, dietro di loro, delle generazioni che l’hanno preceduti. Per dirla con Lacan, l’inconscio è il discorso dell’Altro. Provo, dunque, a riassumere: l’analizzante scopre che laddove pensava che la sua vita psichica gli appartenesse, fosse cioè sotto il suo controllo, così non é, ma, indagando indagando, si accorge che la stessa appartiene agli altri. Magari a quegli altri, la famiglia in primis, da cui credeva o cerca di separarsi. La non padronanza non rinvia, insomma, a chissà quale mistico e oscuro recesso della mente, insondabile e innominabile, ma al peso gravoso di una subita iscrizione nel discorso familiare di cui l’individuo porta inevitabilmente i segni.

    Full Text Available After a brief overwiew on the archival history of the Teutonic Order in the thirteenth and early fourteenth century, the article focuses on the problem of conservation practices and record keeping that the Order adopted during the period of displacement and reorganization of its archives. Two parchment rolls are analyzed, both preserved in the Geheimes Staatsarchiv Preussischer Kulturbesitz in Berlin and containing headings of mostly papal documents issued in favor of the Order in the thirteenth century. The first roll was drawn up at the beginning of the fourteenth century on the documents preserved in the Roman church of Santa Maria in Domnica: the roll is one of the last witnesses of the size of the Roman archive of the Order before its dispersion. The second roll was commissioned in 1318 by the procurator generalis of the Order in the Avignon Curia and was compiled to affirm, first of all, the lawsuit of the Teutonic Knights on rights in Livonia against the archbishop of Riga. The authors of this second roll used, in all probability, compilations made by the will of procuratores of the Order at the Papal Curia ​​in the thirteenth century and based on registers of Papal Chancery.

In the draft Code of Criminal Law, as one of the reform effort is the formulation of offenses of corruption set out in Chapter XXXII starting from Article 688 to Article 702. With the formulation of the offense of corruption and offenses positions formulated in the draft Criminal Code will disregard the Law Combating Corruption although this law of particular importance because of the substance of the articles draft Criminal Code wants to make corruption has become common crimes and do not pass through handling extraordinary.

Uno di questi padri è sicuramente L’amour et l’Occidentdi Denis de Rougemont, il cui approccio “protestante” ai problemi posti dal subito apparire della poesia trobadorica è altrettanto fantasioso e insostenibile di quello “cattolico”. Invero, la passione trobadorica è una sorta di febbre gnostica reperibile in un’area più vasta dell’Europa “Cis-Dardanellica”. Ponendo a confronto i lavori dei Trovatori e di Dante, per esempio, troviamo somiglianze forse non sorprendenti – benché malnote – ma quando scorgiamo analoghe similarità tra Dante e il poeta persiano Hâfez, allora trasaliamo, anche perché l’affinità non si limita ai concetti generali, ma si estende alle immagini retoriche e all’espressione verbale. Qualche prova viene esposta circa questi (e altri contatti letterari tra “Europa” e “Asia”. Il senso di estraneità che pretendiamo spesso di provare di fronte alle culture d’Asia è fatto abbastanza recente.

    Un uomo di 60 anni con ischemia mesenterica cronica (CMI) è stato trattato con una terapia ‘bridge’ verso una terapia di chirurgia open tradizionale, mediante stenting dell’arteria mesenterica superiore (SMA). Al follow-up a 5 mesi lo stent della SMA è andato incontro ad occlusione. Durante questo periodo ‘bridge’ il paziente ha migliorato le sue condizioni generali e il suo indice di massa corporea (BMI) è incrementato da 18 a 22. Il paziente è stato sottoposto successivamente ad intervento chirurgico di bypass iliaco-SMA in configurazione ‘Cloop’. Al follow-up a 6 mesi il bypass è pervio, il paziente non riferisce sintomatologia di CMI ed il suo BMI è di 25. Il trattamento endovascolare non ha precluso una successiva riparazione chirurgica e può essere impiegato in maniera sicura come terapia ‘bridge’. Un miglioramento delle condizioni cliniche, anche durante un limitato periodo ‘bridge’, può migliorare i risultati della terapia chirurgica tradizionale.

    The martensitic microstructures in two high-carbon low alloy steels have been investigated by classical and automated crystallographic analysis under a transmission electron microscope.It is found that the martensitic substructure changes from consisting mostly of transformation twins for 1.20 mass% carbon (C) steel to both transformation twins and planar defects on {101}M for 1.67 mass% C steel.In the 1.67 mass% C steel it is further found that small martensite units have a rather homogeneous substructure,while large martensite units are more inhomogeneous.In addition,the martensite units in both steels are frequently found to be of zigzag patterns and have distinct crystallographic relationships with neighboring martensite units,e.g.kink or wedge couplings.Based on the present findings the development of martensite in high-carbon low alloy steels is discussed and a schematic of the martensite formation is presented.Moreover,whether the schematic view can be applied to plate martensite formation in general,is discussed.

    Translation from the Latin original, "Inventio summae cuiusque seriei ex dato termino generali" (1735). E47 in the Enestrom index. In this paper Euler derives the Euler-Maclaurin summation formula, by expressing y(x-1) with the Taylor expansion of y about x. In sections 21 to 23 Euler uses the formula to find expressions for the sums of the nth powers of the first x integers. He gives the general formula for this, and works it out explicitly up to n=16. In sections 25 to 28 he applies the summation formula to getting approximations to partial sums of the harmonic series, and in sections 29 to 30 to partial sums of the reciprocals of the odd positive integers. In sections 31 to 32, Euler gets an approximation to zeta(2); in section 33, approximations for zeta(3) and zeta(4). I found David Pengelley's paper "Dances between continuous and discrete: Euler's summation formula", in the MAA's "Euler at 300: An Appreciation", edited by Robert E. Bradley, Lawrence A.

    2015-01-01

    This paper introduces a novel path planning algorithm for Unmanned Aerial Vehicle ( UAV ) based on theory of fluid avoiding obstacles. To the problem of path planning which aims at the global optimum, not only the influence of terrain constraints on path safety but also the performance constraints of UAV should be taken into con-sideration, thus a feasible and smooth path will be planned in the three-dimensional space. The computation com-plexity and the path quality by traditional algorithms are usually unsatisfactory, hence we propose the method in-spired by the phenomenon that water can avoid rocks and reach the destination. The common features between this phenomenon and the path planning problem are extracted and analyzed, and then the mathematical model generali-zing the phenomenon is constructed on the basis of theory of fluid mechanics. By selecting the optimal streamline from the fluid field under the evaluation index, the three-dimensional optimal path under flight and environment con-straints is obtained eventually.

    The objective of this study is to examine the treatment performance of vertical flow intermittent feeding constructed wetland (VFCW) in removal of organic pollution, nutrients and color in azo-dye containing wastewater. The systems consisted of PVC reactors, some filling materials such as gravel, sand and zeolite and wetland plants including Typha angustifolia and Canna indica. The average treatment efficiency of the systems for COD, color, sulphate, NH4-N, and PO4-P were in the range of 57-63%, 94-99%, 44-48%, 39-44%, and 84-88%, respectively among the VFCW reactors. It is concluded that VFCW reactor system can effectively be used in the treatment of dye-rich wastewater, especially for the removal of color and in the reduction of COD. Biofilm formation and cleavage of azo bonds could be observed by SEM and FTIR results, respectively. Almost similar NH4-N and PO4-P removal were obtained in all reactors by using same amount of zeolite media.

    This study evaluates the treatment efficiency of horizontal subsurface flow (HSSF) constructed wetland for the removal of AOX (adsorbable organic halides) and chlorophenolics from pulp and paper mill wastewater. The dimensions of HSSF constructed wetland were 3.5 m in length, 1.5 m in width, and 0.28 m in depth, with surface area of 5.25 m2. The HSSF constructed wetland unit was planted with an ornamental plant species, Canna indica. Under hydraulic retention time (HRT) of 5.9 days, the average AOX removal was 89.1%, and 67% to 100% removal of chlorophenolics from pulp and paper mill wastewater was achieved. The complete removal of 2,3-dichlorophenol, 3,4-dichlorophenol, 2,3,5-trichlorophenol, 2,4,6-trichlorophenol, 3,5-dichlorocatechol, 3,6-dichlorocatechol, and 4,5,6-trichloroguaiacol was observed. Some of the chlorophenolics were found to accumulate in the plant biomass and soil. The evapotranspiration rate varied from 6.7 to 12.7 mm day(-1) during the experimental period. The mass balance of chlorophenolics was also studied in constructed wetland system.

    X-ray radiation damage propagation is explored for hydrated starch granules in order to reduce the step resolution in raster-microdiffraction experiments to the nanometre range. Radiation damage was induced by synchrotron radiation microbeams of 5, 1 and 0.3 µm size with ∼0.1 nm wavelength in B-type potato, Canna edulis and Phajus grandifolius starch granules. A total loss of crystallinity of granules immersed in water was found at a dose of ∼1.3 photons nm−3. The temperature dependence of radiation damage suggests that primary radiation damage prevails up to about 120 K while secondary radiation damage becomes effective at higher temperatures. Primary radiation damage remains confined to the beam track at 100 K. Propagation of radiation damage beyond the beam track at room temperature is assumed to be due to reactive species generated principally by water radiolysis induced by photoelectrons. By careful dose selection during data collection, raster scans with 500 nm step-resolution could be performed for granules immersed in water. PMID:20975219

    Microbial nitrogen (N) removal pathways in planted (Canna indica L.) and unplanted integrated vertical-flow constructed wetland systems (IVCWs) were investigated. Results of, molecular biological and isotope pairing experiments showed that nitrifying, anammox, and denitrifying bacteria were distributed in both down-flow and up-flow columns of the IVCWs. Further, the N transforming bacteria in the planted IVCWs were significantly higher than that in the unplanted ones (p<0.05). Moreover, the potential nitrification, anammox, and denitrification rates were highest (18.90, 11.75, and 7.84nmolNg(-1)h(-1), respectively) in the down-flow column of the planted IVCWs. Significant correlations between these potential rates and the absolute abundance of N transformation genes further confirmed the existence of simultaneous nitrification, anammox, and denitrification (SNAD) processes in the IVCWs. The anammox process was the major N removal pathway (55.6-60.0%) in the IVCWs. The results will further our understanding of the microbial N removal mechanisms in IVCWs.

    Total phosphorus (TP) removal performance and application for wastewater treatment of polyphosphate-accumulating bacteria (PAB) in constructed wetlands (CWs) were investigated. In this study, a novel isolated ultraviolet (UV) mutant PZ2 with phosphate-accumulating ability was screened from domestic wastewater and identified as Pseudomonas putida by 16S ribosomal DNA (rDNA) sequencing analysis. The TP removal performance of PZ2 in the synthetic wastewater reached the highest of 93.95 % within 45 h. Two vertical subsurface flow CWs planted with two aquatic macrophytes Canna indica and Acorus calamus were newly designed. After inoculating PZ2 into two CWs within 45 h, the average chemical oxygen demand (COD), TP, and ammonia-nitrogen (NH3-N) removal efficiencies reached 68.50, 60.22, and 66.81 %, respectively. Vegetation type and filter size significantly influenced the TP removal capability of PZ2 in CWs. Meanwhile, considerable qualitative differences were found in the pollutant removal efficiencies of PZ2 with and without CWs in synthetic wastewater. These results could also indicate potential applications of the UV mutagenesis in PAB isolation and the newly designed CWs in wastewater treatments.

    Attempts at medicinal cannabis law reform in Australia are not new. However, in historical perspective 2015 and 2016 will be seen as the time when community debate about legalisation of medicinal cannabis reached a tipping point in a number of Australian jurisdictions and when community impetus for change resulted in major reform initiatives. In order to contextualise the changes, the August 2015 Report of the Victorian Law Reform Commission (VLRC) and then the Access to Medicinal Cannabis Bill 2015 (Vic) introduced in December 2015 into the Victorian Parliament by the Labor Government are scrutinised. In addition, this editorial reviews the next phase of developments in the course of 2015 and 2016, including the Commonwealth Narcotic Drugs Amendment Act 2016 and the Queensland Public Health (Medicinal Canna- bis) Bill 2016. It identifies the principal features of the legislative initiatives against the backdrop of the VLRC proposals. It observes that the principles underlying the Report and the legislative developments in the three Australian jurisdictions are closely aligned and that their public health approach, their combination of evidence-based pragmatism, and their carefully orchestrated checks and balances against abuse and excess constitute a constructive template for medicinal cannabis law reform.

    Management of biomass waste is crucial to the efficiency and sustainable operation of constructed wetlands. In this study, biochars were prepared using the biomass of 22 plant species from constructed wetlands and characterized by BET-N2 surface area analysis, FTIR, TGA, SEM, EDS, and elemental compositions analysis. Biochar yields ranged from 32.78 to 49.02%, with mesopores dominating the pore structure of most biochars. The biochars had a R50 recalcitrance index of class C and the carbon sequestration potential of 19.4-28%. The aquatic plant biomass from all the Chinese constructed wetlands if made into biochars has the potential to sequester 11.48 Mt carbon yr(-1) in soils over long time periods, which could offset 0.4% of annual CO2 emissions from fossil fuel combustion in China. In terms of adsorption capacity for selected pollutants, biochar derived from Canna indica plant had the greatest adsorption capacity for Cd(2+) (98.55 mg g(-1)) and NH4(+) (7.71 mg g(-1)). Whereas for PO4(3-), Hydrocotyle verticillata derived biochar showed the greatest adsorption capacities (2.91 mg g(-1)). The results from this present study demonstrated that wetland plants are valuable feedstocks for producing biochars with potential application for carbon sequestration and contaminant removal in water remediation.

    A series of investigations were conducted to evaluate the feasibility of using constructed wetlands to remove pollutants from seafood processing wastewater. Six emergent plant species; Cyperus involucratus, Canna siamensis, Heliconia spp., Hymenocallis littoralis, Typha augustifolia and Thalia deabata J. Fraser were planted in surface flow wetland. They were fed with seafood wastewater that was 50% diluted with treated seafood wastewater from an aerated lagoon. All macrophytes were found to meet satisfying treatment efficiency (standard criteria for discharged wastewater) at 5 days hydraulic retention time (HRT). While C. involucratus, T. deabata and T. augustifolia met acceptable treatment efficacy at 3 days HRT. Nutrient uptake rate of these species was observed in the range of 1.43-2.30 g Nitrogen/m(2)day and 0.17-0.29 g Phosphorus/m(2)day, respectively at 3 days HRT. The highest treatment performances were found at 5 days HRT. Average removal efficiencies were 91-99% for BOD(5), 52-90% for SS, 72-92% for TN and 72-77% for TP. Plant growth and nitrogen assimilation were experienced to be most satisfactory for C. involucratus, T. deabata and T. augustifolia. Lower HRTs affected contaminant removal efficiency for all species. C. involucratus, T. deabata and T. augustifolia can remove all contaminants efficiently even at the lowest hydraulic retention time (1 day).

    Full Text Available The tropical emergent plant species; Cyperus involucratus, Canna siamensis, Heliconia sp., Hymenocallis littoralis, Typha augustifolia and Thalia dealbata were used to observe nutrients (total phosphorus: TP and total nitrogen: TN removal efficiencies of surface flow constructed wetland (SFCW. The system was operated at different hydraulic retention time (HRT of 1, 3 and 5 days and the average atmospheric temperature of 29.1 ± 4.9oC. The seafood industrial wastewater was employed as the influent. The high biomass production plant species; Cyperus involucratus, Typha augustifolia and Thalia dealbata could generate the high oxidative environment. Amount of N and P accumulations in plant tissue were increased with the increase of plant biomass production. The system did not show any significantly different on N and P accumulations among the tested-emergent plant species. But the amount of accumulated-N and P were increased with the increase of HRT. N accumulations in plant tissue, effluent, sediment and media of the system with the tested-emergent plant species under HRT of 1-5 days were in the range of 2.17-43.80%, 7.91-27.75%, 19.62-36.86% and 14.39-31.88%, respectively. Also, P accumulations were 0.79-17.01%, 20.35-28.37%, 40.96-56.27% and 9.09-20.47%, respectively.

    Paraquat has been shown to be a highly toxic compound for humans and animals, and many cases of acute poisoning and death have been reported over the past few decades. The present study was undertaken to evaluate comprehensively herbicides (Paraquat) and some plant extracts to biochemical aspects of Lymnaea natalensis snails. It was found that the exposure of L. natalensis to Paraquat and plant extracts led to a significant reduction in the infectivity of Fasciola gigantica miracidia to the snail. The glucose level in hemolymph of exposed snails was elevated, while the glycogen showed a decrease in soft tissues when compared with the control group. In addition, the activity level of some enzymes representing glycolytic enzymes as hexokinase (HK), pyruvate kinase (PK), phosphofructokinase (PFK), lactate dehydrogenase (LDH), and glucose phosphate isomerase (GPI) in snail's tissues were reduced in response to the treatment. It was concluded that the pollution of the aquatic environment by herbicide would adversely affect the metabolism of the L. natalensis snails. Snails treated with Agave attenuate, Ammi visnaga, and Canna iridiflora plant had less toxic effect compared to snails treated with Paraquat.

    Four plant species, Typha orientalis, Scirpus validus, Canna indica and Iris tectorum were selected to assess their physiological response and effects on nitrogen and COD removal to high total ammoniacal nitrogen (TAN) in constructed wetlands. Results showed that high TAN caused decreased relative growth rate, net photosynthetic rate, and leaf transpiration. C. indica and T. orientalis showed higher TAN adaptability than S. validus and I. tectorum. Below TAN of 200 mg L(-1), growth of C. indica and T. orientalis was less affected or even stimulated at TAN range 100-200 mg L(-1). However, S. validus and I. tectorum was obviously suppressed when TAN was above 100 mg L(-1). High TAN generated obvious oxidative stress showing increased proline and malondialdehyde contents, and superoxide dismutase was inhibited. It indicated that the threshold for plant self-bioremediation against high TAN was 200 mg L(-1). What's more, planted CWs showed higher nitrogen and COD removal. Removal rate of C. indica and T. orientalis was higher than S. validus and I. tectorum.

    Viscosity reduction has a great impact on the efficiency of ethanol production when using roots and tubers as feedstock. Plant cell wall-degrading enzymes have been successfully applied to overcome the challenges posed by high viscosity. However, the changes in cell wall polymers during the viscosity-reducing process are poorly characterized. Comprehensive microarray polymer profiling, which is a high-throughput microarray, was used for the first time to map changes in the cell wall polymers of sweet potato (Ipomoea batatas), cassava (Manihot esculenta), and Canna edulis Ker. over the entire viscosity-reducing process. The results indicated that the composition of cell wall polymers among these three roots and tubers was markedly different. The gel-like matrix and glycoprotein network in the C. edulis Ker. cell wall caused difficulty in viscosity reduction. The obvious viscosity reduction of the sweet potato and the cassava was attributed to the degradation of homogalacturonan and the released 1,4-β-d-galactan and 1,5-α-l-arabinan.

    In the present article the FTIR spectra of the wild and planting Gastrodia elata Bl. from different habitats and its confusable varieties such as Canna edulis Ker-Gawl, Colocasia esculenta (L.) Schott and Solanum tuberosum L. were obtained by horizontal attenuated total reflection infrared spectroscopy (HATR-FTIR), and were all transformed by Fourier self-deconvolution. The authors investigated the discrepancy extent of Fourier self-deconvolution of Gastrodia elata Bl and confusable varieties under various bandwidth and enhancement, and found that the discrepancy extent of Gastrodia elata Bl and confusable varieties was the most obvious when the bandwidth was between 75.0 and 76.0 and enhancement was 3.2. By adopting Fourier self-deconvolution infrared spectroscopy (FSD-IR) analytical method the samples were studied in detail. The results showed that we could find out the difference among them by means of Fourier self-deconvolution infrared spectroscopy, although it was very difficult to find out the difference in FSD-IR spectra of wild and planting Gastrodia elata Bl., and asexual reproduction and sexual reproduction Gastrodia elata Bl. The difference in FSD-IR spectra between Gastrodia elata Bl. and its confusable varieties is also very great. Therefore, this method can be used to recognize different Gastrodia elata Bl. and its confusable varieties simply, rapidly and accurately.

    Radiation damage propagation was examined in starch granules by synchrotron radiation micro- and nano-diffraction techniques from cryo- to room temperatures. Careful dose limitation allowed raster-diffraction experiments with 500 nm step resolution to be performed. X-ray radiation damage propagation is explored for hydrated starch granules in order to reduce the step resolution in raster-microdiffraction experiments to the nanometre range. Radiation damage was induced by synchrotron radiation microbeams of 5, 1 and 0.3 µm size with ∼0.1 nm wavelength in B-type potato, Canna edulis and Phajus grandifolius starch granules. A total loss of crystallinity of granules immersed in water was found at a dose of ∼1.3 photons nm{sup −3}. The temperature dependence of radiation damage suggests that primary radiation damage prevails up to about 120 K while secondary radiation damage becomes effective at higher temperatures. Primary radiation damage remains confined to the beam track at 100 K. Propagation of radiation damage beyond the beam track at room temperature is assumed to be due to reactive species generated principally by water radiolysis induced by photoelectrons. By careful dose selection during data collection, raster scans with 500 nm step-resolution could be performed for granules immersed in water.

    The influence of microflora in the utilization of starches, the X ray pattern which was of A or B type, was studied by balances and carcasses analysis with growing axenic or holoxenic chickens, put in isolators. Five tropical tubers were used : Manihot utilissima and Dioscorea dumetorum of A-type, Dioscorea cayenensis and alata and Canna edulis of B-type. They were introduced in isoenergetic (4,460 Kcal/g D.M.) and isoproteic (18 p. 100) diets. The A-type starches are entirely digested (95 p. 100) and the B-type are poorly digested (40-60 p. 100). The first ones induced a better growth than the second. The influence of digestive microflora changes with the two types of tubers used. With A-type starches the microflora lowered the feed intake, the growth and the energy and protein efficiency respectively--25 and--10 p. 100. When the diet included tubers with B-type starches, the low digestibility of starch and the low metabolisable energy in the diets induced poor growth and retentions. The results are discussed in relation with the starch breakdown into glucose, lactic acid and volatile fatty acids.

    X-ray radiation damage propagation is explored for hydrated starch granules in order to reduce the step resolution in raster-microdiffraction experiments to the nanometre range. Radiation damage was induced by synchrotron radiation microbeams of 5, 1 and 0.3 µm size with ∼0.1 nm wavelength in B-type potato, Canna edulis and Phajus grandifolius starch granules. A total loss of crystallinity of granules immersed in water was found at a dose of ∼1.3 photons nm(-3). The temperature dependence of radiation damage suggests that primary radiation damage prevails up to about 120 K while secondary radiation damage becomes effective at higher temperatures. Primary radiation damage remains confined to the beam track at 100 K. Propagation of radiation damage beyond the beam track at room temperature is assumed to be due to reactive species generated principally by water radiolysis induced by photoelectrons. By careful dose selection during data collection, raster scans with 500 nm step-resolution could be performed for granules immersed in water.

    The objective of this paper was to evaluate the efficiency of micropollutant removal, such as Cu, Zn, carbamazepine, and linear alkylbenzene sulfonates (LAS), through the use of a subsurface vertical flow constructed wetland system with ornamental plants. Zantedeschia aethiopica, Canna indica, Carex hirta, Miscanthus sinensis, and Phragmites australis were selected and planted in lysimeters filled up with gravel. The lysimeters were completely saturated with synthetic wastewater (N 280 mg L(-1), P 30 mg L(-1), Cu 3.6 mg L(-1), Zn 9 mg L(-1), carbamazepine 5 μg L(-1), linear alkylbenzene sulfonates 14 mg L(-1)), and the leaching water was collected for analysis after 15, 30, and 60 days in winter-spring and spring-summer periods. Nutrients (N and P) and heavy metals decreased greatly due to both plant activity and adsorption. C. indica and P. australis showed the highest metal content in their tissues and also the greatest carbamazepine and LAS removal. In these plants, the adsorption/degradation processes led to particularly high oxidative stress, as evidenced by the significantly high levels of ascorbate peroxidase activity detected. Conversely, Z. aethiopica was the less efficient plant in metal and organic compound removal and was also less stressed in terms of ascorbate peroxidase activity.

    Full Text Available ABSTRACT Urban rainfall runoff pollution has become a major reason for water eutrophication problem in the process of urbanization in China, while phosphorus is a significant restrictive factor that influences primary productivity of freshwater system. It's rather significant to conduct phosphorus control in waste water with engineering measures. This research, based on material balance research of phosphorus in artificial wetlands, HRT (hydraulic retention time and analysis of wetland plant photosynthesis and removal rate of phosphorus, simulates purification of phosphorus in urban runoff sewage by artificial wetland system. Experiment shows that removal rate of total phosphorus in urban runoff sewage by artificial wetland system reaches 42.23%-60.89%, and contribution rate in removal of phosphorus which is assimilated and absorbed by plants is 14.74%; contribution rate in removal of phosphorus which is accumulated and absorbed by substrates is 43.22%; contribution rate in removal of phosphorus which is absorbed by means like microorganisms is 2.93%. Pollutant absorption by substrates is a process of dynamic equilibrium. With extension of HRT, phosphorus removing effect of wetlands present an increasing and then decreasing tendency; Net photosynthetic rate and TP removal rate of canna and reed have significant positive correlation, and correlation coefficients are respectively 0.941(P<0.001 and 0.915(P<0.05. Substrates and plants are main pathways for phosphorus removal of artificial wetlands, covering 95% of the total removing effect.

    A comparative study of the efficiency of contaminant removal between five emergent plant species and between vegetated and unvegetated wetlands was conducted in small-scale (2.0 m×1.0 m×0.7 m, length×width×depth) constructed wetlands for domestic wastewater treatment in order to evaluate the decontaminated effects of different wetland plants. There was generally a significant difference in the removal of total nitrogen (TN) and total phosphorus (TP), but no significant difference in the removal of organic matter between vegetated and unvegetated wetlands.Wetlands planted with Canna indica Linn., Pennisetum purpureum Schum., and Phragmites communls Trin. had generally higher removal rates for TN and TP than wetlands planted with other species. Plant growth and fine root (root diameter ≤ 3 mm) biomass were related to removal efficiency. Fine root biomass rather than the mass of the entire root system played an important role in wastewater treatment. Removal efficiency varied with season and plant growth. Wetlands vegetated by P. purpureum significantly outperformed wetlands with other plants in May and June, whereas wetlands vegetated by P. communis and C. indica demonstrated higher removal efficiency from August to December. These findings suggest that abundance of fine roots is an important factor to consider in selecting for highly effective wetland plants. It also suggested that a plant community consisting of multiple plant species with different seasonal growth patterns and root characteristics may be able to enhance wetland performance.

    Conotoxin GeXIVAWT is a 28-amino acid peptide containing two pairs of disulfide bond isolated from the venom of worm-hunting Conus generalis Lonnaeus. Usually, the conotoxins produced by means of chemical synthesis was low yield, and it was difficult to be purified. A simple and fast strategy of producing disulfide-rich conotoxins via recombinant expression was presented. The codons of novel conotoxin GeXIVAWT gene were optimized. Two pairs of primers were generated by chemical synthesis for construction of expression vectors. Recombinant expression vector pET22b ( + )/pelB-GeXIVAWT fused with pelB signal peptide was successfully expressed in Escherichia coli. Recombinant pelB-GeXIVAWT without His-tag was purified by low concentrations of urea and ultrafiltration tube. Inactive inclusion bodies were transformed into active recombinant conotoxins by using dilution refolding method. It was further purified using HPLC and identified by mass spectrometry. Renaturing in vitro and biological activity experiment showed that the pelB-GeXIVAWT could inhibited the growth of Spodoptera frugiperda 9 (Sf-9) cell, as a foundation for the study of efficient insecticides.%芋螺毒素GeXIVAWT是来自食虫将军芋螺(Conus generalis Lonnaeus)毒管中,具有两对二硫键的28肽.通过化学合成这种芋螺毒素产量低、成本高、难以纯化.利用简单快速的重组表达来生产富含二硫键的芋螺毒素有可能成为有效的新途径.通过对芋螺毒素GeXIVAWT的基因进行密码子优化,人工合成引物来构建表达载体pET22b(+)/pelB-GeXIVAWT.融合了信号肽的重组芋螺毒素以包涵体的形式在大肠杆菌中获得了高效表达.利用低浓度尿素洗涤和超滤管进行纯化无组氨酸标签的重组芋螺毒素pelB-GeXIVAWT,再利用稀释复性的方法将无活性的包涵体转变成具有活性的重组芋螺毒素.复性后的重组蛋白采用反相高效液相色谱进一步纯化后进行了质

Entrambi i provvedimenti legislativi compiono un importante passo in avanti nell’attuazione della democrazia di prossimità a livello locale, integrando – e, in alcuni casi, sostituendo – le procedure e le garanzie procedurali predisposte a livello nazionale. La presente nota analizza i processi partecipativi istituiti dalle leggi in oggetto. A tal fine, descrive e compara gli organi amministrativi che queste istituiscono, le procedure amministrative cui questi ultimi sono preposti, nonché il rapporto tra sfera amministrativa e sfera politica regionali. Con particolare riferimento al caso toscano si analizzano la struttura amministrativa indipendente che cura lo svolgimento delle procedure consultive presso le parti interessate e le relative funzioni (acquisizione e valutazione delle istanze provenienti dai portatori di interessi e, più in generale, garanzia della maggiore trasparenza e democraticità delle procedure decisionali. Si analizza, inoltre, il contesto normativo di riferimento. All’analisi dei profili generali segue quella di dettaglio: viene descritta, dapprima, la posizione dei soggetti portatori di interessi e i diritti endo-procedimentali loro riconosciuti e, in seguito, si esaminano le strutture partecipative e Le procedure a ciò predisposte. Quanto invece al caso dell’Emilia Romagna, si descrivono l’attività svolta dal Tecnico di garanzia in materia di partecipazione e le funzioni attribuite al Comitato di pilotaggio, due organi amministrativi disciplinati dalla legge. La parte conclusiva dell’articolo sviluppa alcune riflessioni d’insieme in merito ai due sistemi partecipativi introdotti dai Legislatori della Toscana e dell’Emilia Romagna, soffermandosi in particolar modo sulle relative aree di criticità. Si valutano poi l’impatto delle scelte legislative sulla possibilita che i portatori di interesse contribuiscano

    Palynological investigation of the Cretaceous Abu Roash, Bahariya, Kharita, Alamein, Alam El Bueib and Betty formations, encountered in the Gebel Rissu-1 well, north Western Desert, Egypt yielded 27 species of pteridophytic spores, 24 of gymnosperm pollen, 25 of angiosperm pollen and 11 of dinoflagellate cysts in addition to some acritarchs, foraminiferal test linings and freshwater algae. This enabled us to recognize five miospore biozones arranged from youngest to oldest as: Classopollis brasiliensis- Afropollis cf. kahramanensis- Dichastopollenites ghazalataensis Assemblage Zone (Late Cenomanian); Elaterosporites klaszii- Sofrepites legouxae- Afropollis jardinus Assemblage Zone (Middle/Late Albian-Early Cenomanian); Pennipollis peroreticulatus- Duplexisporites generalis-Tricolpates Assemblage Zone (Early Aptian-Early Albian); Tucanopollis crisopolensis- Afropollis sp. Assemblage Zone (Barremian) and Appendicisporites cf. tricornitatus- Ephedripites spp. Assemblage Zone (Late Neocomian). The Early Cretaceous Kharita, Alam El Bueib and the Betty formations encountered in the Gebel Rissu-1 well are interpreted to indicate oxic proximal and distal shelf deposits, characterized by type III/IV, V kerogen, which is gas prone but having little potential to produce hydrocarbons. The Upper Cretaceous Abu Roash and Bahariya formations are characterized by a distal suboxic-anoxic and marginal dysoxic-anoxic environment, and their kerogen type III/II indicates gas/oil prone nature. The Bahariya and Kharita Albian-Cenomanian sediments in the present study witnessed the onset of a semi-arid to arid climate, with local or seasonal humid conditions, based on the continuous high abundance of the elaterates pollen and Afropollis-producing plants that inhabited the paleotropical humid coastal plains.

    An experiment was carried out to investigate the relative bioavailability of tribasic zinc (Zn) sulfate relative to Zn sulfate for broilers fed a conventional corn-soybean meal diet. A total of 504 1-d-old Arbor Acres commercial male chicks were randomly assigned by body weight of birds to one of seven treatments involving a 2×3 factorial arrangement with three levels of added Zn (30, 60, or 90 mg of Zn kg–1) and two Zn sources (tribasic Zn sulfate and Zn sulfate) plus a control with no added Zn for an experimental phase of 14 d. Plasma Zn, tibia ash Zn, pancreas Zn, and pancreas metalothionein (MT) messenger RNA (mRNA) were analyzed at 6 or 14 d of age post-hatching. The results showed that plasma Zn, tibia ash Zn, pancreas Zn, and pancreas MT mRNA increased linearly (P<0.002) as dietary Zn concentration increased at 6 or 14 d of age. The R2 for a linear model was greater on d 6 than on d 14 for the above 4 responsive criteria, and among these indices, the iftting of the tibia ash Zn concentration was the best (R2=0.99). Therefore, based on slope ratios from the multiple linear regressions of the above 4 indices of the birds at 6 d of age on daily intake of dietary Zn, the bioavailabilities of tribasic Zn sulfate relative to Zn sulfate (100%) were 95.6% (P=0.18), 83.5% (P=0.01), 87.9% (P=0.53), and 75.9% (P=0.38) for the tibia ash Zn, pancreas Zn, plasma Zn, and pancreas MT mRNA, respectively. The results indicated that generaly, Zn from tribasic Zn sulfate was as available as Zn from Zn sulfate for broilers.

Questo lavoro vuole presentare i risultati di uno studio ricostruttivo condotto filologicamente su alcuni monumenti di Siracusa in età greca, cercando di evidenziare il contributo specifico dell'archeologia virtuale nei processi interpretativi, al fine di proporre una presentazione efficace rivolta ad un target specifico di turisti. Seguendo questo approccio sono stati ricostruiti il Tempio di Apollo, il complesso monumentale di piazza Duomo ed il Teatro greco, cercando di fornire output di visualizzazione che fossero adeguati ad una consultazione da smartphone e coerenti alle finalità generali del progetto "PON Energia Smart City". Questo progetto prevede un approccio "smant" alla visita di Siracusa, privilegiando principalmente logiche di fruizione efficiente on-site grazie all'adozione di tecnologie basate sulla Realtà Aumentata, la visione dei monumenti da punti inusuali e la visita virtuale multimodale dei punti di interesse. Emerge da questo studio la nuova fisionomia di quei monumenti che, per motivi diversi, sono stati rappresentati negli anni in forme e modi del tutto differnti, tali da rendere a volte irriconoscibili le diverse ricostruzioni dello stesso oggetto. Grazie alle tecnologie di restituzione 3D basate sull'immagine è stato possibile integrare le parti mancanti di alcuni elementi architettonici e scultorei che, ricollocati virtualmente nella posizione originaria, permettono una lettura dinamica che combina l'aspetto reale con quello virtuale.

    Full Text Available In the field of the building techniques used in the construction of the walls, the majority of the classifications consists of the formal aspects of visible surfaces. These classifications use some attentions distinguishing stratigraphic units and in the field of the aesthetic aspects of surfaces. As the walls take part of the most important load-bearing structure, isn’t possible to speak of the techniques used in the construction of the walls without trying to understand how the different types of wall effectively operate from a static point of view. So it’s necessary to check and to understand the whole volume of each technique used in the construction of the walls, and if there are general or particular rules deductibles from the visible surfaces. In this paper we suggest, also, an classification of the «families» of the most recognized techniques used in the construction of the walls, on the basis of their constructive, functional and formal systems.La maggior parte delle classificazioni dei modi di costruire murari si basa sugli aspetti formali delle superfici visibili, con certe utilità nel distinguere le unità stratigrafiche murarie e negli aspetti estetici delle superfici stesse. Dal momento però che i muri fanno parte delle strutture portanti più importanti, non si può parlare di tecniche murarie senza cercare di capire come i vari tipi classificati si comportino realmente dal punto di vista statico. Si cerca perciò di verificare e in qualche modo di capire l’intero volume di ogni tecnica muraria, e se vi siano della regole generali o particolari che siano in qualche modo deducibili anche dalle superfici visibili. Si propone infine una classificazione delle «famiglie» di tecniche murarie più note sulla base dei loro sistemi costruttivi e funzionali, oltre che formali.

  6. An axion-induced SM/MSSM Higgs landscape and the Weak Gravity Conjecture

    Science.gov (United States)

    Herráez, Alvaro; Ibáñez, Luis E.

    2017-02-01

    We construct models in which the SM Higgs mass scans in a landscape. This is achieved by coupling the SM to a monodromy axion field through Minkowski 3-forms. The Higgs mass scans with steps given by δm H 2 ≃ ημf, where μ and f are the axion mass and periodicity respectively, and η measures the coupling of the Higgs to the associated 3-form. The observed Higgs mass scale could then be selected on anthropic grounds. The monodromy axion may have a mass μ in a very wide range depending on the value of η, and the axion periodity f . For η ≃ 1 and f ≃ 1010 GeV , one has 10-3 eV ≲ μ ≲ 103 eV, but ultralight axions with e.g. μ ≃ 10-17 eV are also possible. In a different realization we consider landscape models coupled to the MSSM. In the context of SUSY, 4-forms appear as being part of the auxiliary fields of SUSY multiplets. The scanning in the 4-forms thus translate into a landscape of vevs for the N = 1 auxiliary fields and hence as a landscape for the soft terms. This could provide a rationale for the MSSM fine-tuning suggested by LHC data. In all these models there are 3-forms coupling to membranes which induce transitions between different vacua through bubble nucleation. The Weak Gravity Conjecture (WGC) set limits on the tension of these membranes and implies new physics thresholds well below the Planck scale. More generaly, we argue that in the case of string SUSY vacua in which the Goldstino multiplet contains a monodromy axion the WGC suggests a lower bound on the SUSY breaking scale m 3/2 ≳ M s 2 / M p .

    2015-01-01

    BACKGROUND:Shoulder pain is a common complication of stroke. Bee venom acupuncture (BVA) is increasingly used in the treatment of post-stroke shoulder pain. OBJECTIVE: To summarize and evaluate evidence on the effectiveness of BVA in relieving shoulder pain after stroke. SEARCH STRATEGY: Nine databases, namely MEDLINE, EMBASE, the Cochrane Library, the China National Knowledge Infrastructure (CNKI), the Japan Science and Technology Information Aggregator, Electronic (J-STAGE), and four Korean medical databases, namely, the National Assembly Library, the Research Information Service System, the National Discovery for Science Leaders, and OASIS, were searched from their inception through August 2014 without language restrictions. INCLUSION CRITERIA: Randomized controled trials (RCTs) were included if BVA was used at acupoints as the sole treatment, or as an adjunct to other treatments, for shoulder pain after stroke. DATA EXTRACTION AND ANALYSIS:Two review authors independently selected trials for inclusion, assessed methodological quality and extracted data. RESULTS: A total of 138 potentialy relevant articles were identiifed, 4 of which were RCTs that met our inclusion criteria. The quality of studies included was generaly low, and a preponderance of positive results was demonstrated. Al four trials reported favorable effects of BVA on shoulder pain after stroke. Two RCTs assessing the effects of BVA on post-stroke shoulder pain, as opposed to saline injections, were included in the meta-analysis. Pain was signiifcantly lower for BVA than for saline injections (standardized mean difference on 10-cm visual analog scale: 1.46 cm, 95% CI = 0.30–2.62,P = 0.02, n = 86) CONCLUSION: This review provided evidence suggesting that BVA is effective in relieving shoulder pain after stroke. However, further studies are needed to conifrm the role of BVA in aleviating post-stroke shoulder pain. Future studies should be conducted with large samples and rigorous study designs.

With this objective, a new progestin, chlormadinone acetate (CMA, has been developed as a derivative of progesterone for ­contraception. This new molecule has been introduced in combination with ethinylestradiol (EE 30 µg as a safe ­contraceptive with antiandrogenic properties. Many clinical studies have investigated this new oral combination and found it to be safe, with a Pearl Index similar to that of other combined hormonal contraceptives. CMA, because of its antiandrogenic properties, has been also considered effective for resolution of acne, seborrhea, and hirsutism. The data show it to be a safe molecule in terms of glucose and lipid metabolism. No major weight changes have been linked with its use, and it seems to be the only progestin able to reduce fat mass during use. The CMA-EE combination is well tolerated and acceptable to women. Adverse events related to its use are similar to those reported with other third-generation ­contraceptives. We can conclude that CMA-EE is an effective, safe, and well tolerated ­antiandrogenic hormonal contraceptive.Keywords: chlormadinone acetate, acne, weight, metabolism, safety, hormonal contraceptive

    OBJECTIVE:There is increasing interest in complementary and alternative medicine generaly, and especialy by those affected by chronic diseases, such as diabetes melitus. We aimed to determine the prevalence and pattern of complementary and alternative medicine use among patients suffering from diabetes melitus in Shiraz, southern Iran. Another objective was to explore associated factors for use of complementary and alternative medicine among patients with diabetes melitus. METHODS: A 19-item semi-structured questionnaire (open- and close-ended) was administered to 239 patients with diabetes melitus in this cross-sectional study. It was carried out in two outpatient diabetes clinics afifliated with the Shiraz University of Medical Sciences, Shiraz, Iran. RESULTS:One hundred and eighty patients (75.3%) used at least one type of complementary and alternative medicine in the last year prior to the interview. Patients with diabetes melitus who were living in a large family (≥ 5 members), not taking insulin, and believed that complementary and alternative medicine have synergistic effects with conventional medicine, were independently and signiifcantly (P values: 0.02, 0.04, and 0.01, respectively) more likely to use complementary and alternative medicine. Most of the users (97.7%) reported use of herbal preparations, and 89.4% of users did not change their medication, neither in medication schedule nor its dosage. CONCLUSION: The use of complementary and alternative medicine, especialy herbal remedies, is popular among diabetes patients in Shiraz, Iran. This use is associated with patients’ family size, type of conventional medications and their view about concomitant use of complementary and conventional medicine.

    2012-04-01

    This work aims to contribute to knowledge on the phenomena of sinkholes in the urban area of Carbonia, primed mostly as a result of mining in underground coal Sulcis, as well as natural causes, in the hills and valleys structurated on the bedrock of Cambrian area, in the localities of Cannas and Serbariu. During the exploitation of the coal deposits, (so called Lignitifero), mines of the Sulcis Area, in over a century of mining, have produced large underground excavations, which were extracted more than 50 million tons of coal and large quantities of tailings. On older crops of mineral minings centers of Serbariu, Cortoghiana and Bacu Abis, the mining operations reached the depth of 300 meters from the surface of the country, over 100 meters below sea level. In the late of 1960, following the closure of the mines, were manifested in the temporal effects of the disruptions caused by the collapse of underground voids, affecting a much wider area of the below mining cultivations. The first signs of instability are occurred with the sudden opening of large potholes and structural damage to buildings up area of Bacu Abis, in neighboring areas to the Mine of Serbariu, intended for production facilities ("Su Landiri Durci"), and along certain streets service. In the case of mine "Serbariu" located on the outskirts of the urban west Carbonia, exploited in the period between 1940 and 1964, the cultivation of the layers of coal left in place, at short depth from the surface level, consisting of empty mines, with more than 5 km of galleries. So, have been found important effects of instability of the soil in urban areas and in the recently built road infrastructure linking lots of settlements. The area affected by mining operations has an area of over 4 square kilometers, is covered in part by the built environment and road infrastructure of regional and state level. In the mining center, now converted to craft and commercial area, have continued various undergrounds mining

    The purpose of this study is to examine on removal of arsenic from water by biosorption through potential application of herbal dye wastes. Four different flower dye residues (after extraction of natural dye) viz. Hibiscus rosasinensis, Rosa rosa, Tagetes erecta, and Canna indica were utilized successfully for the removal of arsenic from aqueous solution. Batch studies were carried out for various parameters viz. pH, sorbent dose, contact time, initial metal ion concentration, and temperature. Data were utilized for isothermal, kinetic, and thermodynamic studies. Scanning electron microscopy (SEM), energy-dispersive x-ray spectroscopy (EDAX), and Fourier transform infrared (FTIR) analyses of biomass were performed. The results showed that 1 g/100 ml for 5.0-5.5 h contact time at pH 6.0-7.5 with agitation rate 150 rpm provided 98, 96, 92, and 85 % maximum absorption of arsenic by R. rosa, H. rosasinensis, T. erecta, and C. indica, respectively, at initial concentration of 500 ppb. Data followed Langmuir isotherm showing sorption to be monolayer on heterogeneous surface of biosorbent. Negative values of ΔG° indicated spontaneous nature, whereas ΔH° indicates exothermic nature of system followed by pseudo-first-order adsorption kinetics. FTIR results showed apparent changes in functional group regions after metal chelation. SEM and EDAX analyses showed the changes in surface morphology of all test biosorbents. Herbal dye wastes, used as biosorbent, exhibited significant (85-98 %) removal of arsenic from aqueous solution. Hence, these biosorbents are cost-effective, easily available, eco-friendly, and comparatively more effective than other biosorbents already in use. These may be used to remove arsenic and other toxic metals from water.

  3. The geomorphology of a glaciated continental shelf, Western Scotland, UK

    2013-04-01

    We present recently collected swath bathymetry and legacy seismic data from two regions of the north-west UK continental shelf: the Sea of the Hebrides; and the Firth of Lorn, western Scotland. Both regions have experienced extensive Pleistocene ice sheet glaciation and both provide abundant geomorphological evidence of subglacial and postglacial processes. The Sea of the Hebrides bathymetry data cover 2200 km2 and provide new geomorphological evidence for an ice stream flowing from western Scotland and the Inner Hebrides focusing towards a trough-mouth fan (the Barra Fan) at the continental shelf break during the height of the last glaciation. Notably, bedrock structures provide a control on the location and orientation of glacially overdeepened basins and troughs on the inner shelf. Whilst around the Islands of Canna and Rum, convergent seabed glacial lineations and other subglacially streamlined features eroded in bedrock preserve the direction of ice sheet movement - indicating ice streaming in a south-westerly direction across the continental shelf. We propose that this fast-flow zone formed part of a larger convergent ice stream system draining much of western Scotland and the north of Ireland. The Firth of Lorn bathymetry acquisition comprises 553km2 of data, collected as part of the INIS Hydro program (Ireland, Northern Ireland and Scotland Hydrographic Survey). This region of nearshore continental shelf is revealed as predominantly bedrock-dominated seabed, characterised by a series of narrow, strongly fault-controlled troughs, part of the Great Glen Fault Zone complex. Evidence for glaciation is widespread and well preserved in the Firth of Lorn and surrounding seabed with moraines, bedrock lineations (?megagrooves?) and overdeepened basins common across the area. Initial mapping shows that our understanding of the configuration and style of deglaciation in these sectors of the former British-Irish Ice Sheet can be greatly improved by the collection of

    Ferric-Carbon Micro-Electrolysis (Fe/C-M/E) material had been widely used for the pretreatment of wastewater. Therefore, we hypothesized that Fe/C-M/E material could enhance the treatment of domestic sewage when integrated into CWs. In this study, constructed wetlands (CWs) integrated with Fe/C-M/E material were developed. During the experiment of vegetation influence, percentages of NH4(+)-N, NO3(-)-N, TN, and COD removed in polyculture (W1) were up to 91.8%, 97.0%, 92.3%, and 85.4%, respectively, which were much higher than those in Lythrum salicaria monoculture (W2) and Canna indica monoculture (W3). In the experiment of temperature influences, temperature substantially influenced the performance of CWs. For example, NO3(-)-N removal percentages of W1, W2 and W3 at high temperature (25.5°C and 19.8°C) were relatively stable and greater than 85.4%. At 8.9°C, however, a sharp decline of NO3(-)-N removal percentage was observed in all CWs. Temperature also influenced the COD removal and soil microbial activity and biomass. Overall, the polyculture showed the best performance during most of the operating time, average temperature ≥ 19.8°C, due to the functional complementarity between vegetation. All the CWs consistently achieved high removal efficiency (above 96%) for TP in all experiments, irrespective of vegetation types, phosphorous loadings and temperatures. In conclusion, polyculture was an attractive solution for the treatment of domestic sewage during most of the operating time, average temperature ≥ 19.8°C). Furthermore, CWs with Fe/C-M/E material were ideally suitable for domestic sewage treatment, especially for TP removal.

    The operational performance of a full-scale subsurface-flow constructed wetland, which treated the mixed industrial and domestic wastewater with BOD5/COD mean ratio of 0.33 at Shatian, Shenzhen City was studied. The constructed wetland system consists of screens, sump, pumping station, and primary settling basin, facultative pond, first stage wetland and secondary stage wetland. The designed treatment capacity is 5000 m3/d, and the actual influent flow is in the range of 10000 m3/d. Under normal operational conditions, the final effluent quality well met the National Integrated Wastewater Discharge Standard(GB 8978-1996), with the following parameters(mean values): COD 33.90 mg/L, BOD5 7.65 mg/L, TSS 7.92 mg/L, TN 9.11 mg/L and TP 0.56 mg/L. Seven species of plants were selected to grow in the wetland: Reed, Sweetcane flower Silvergrass, Great Bulrush, Powdery Thalia and Canna of three colours. The growing season is a whole year-round. The seasonal discrepancy could be observed and the plants growing in the wetland are vulnerable to lower temperature in winter.The recycling of the effluent in the first stage of the wetland system is an effective measure to improve the performance of the wetland system. The insufficient DO value in the wetland system not only had significant effect on pollutants removal in the wetland, but also was unfavourable to plant growth. The recycling of effluent to the inlet of wetland system and artificial pond to increase DO value of influent to the wetland is key to operate the subsurface constructed wetland steadily and effectively.

    The production of bioactive polypeptides (peptaibiotics) in vivo is a sophisticated adaptation strategy of both mycoparasitic and saprotrophic Trichoderma species for colonizing and defending their natural habitats. This feature is of major practical importance, as the detection of peptaibiotics in plant-protective Trichoderma species, which are successfully used against economically relevant bacterial and fungal plant pathogens, certainly contributes to a better understanding of these complex antagonistic interactions. We analyzed five commercial biocontrol agents (BCAs), namely Canna(®) , Trichosan(®) , Vitalin(®) , Promot(®) WP, and TrichoMax(®) , formulated with recently described species of the Trichoderma harzianum complex, viz. T. afroharzianum, T. simmonsii, and T. guizhouense. By using the well-established, HPLC/MS-based peptaibiomics approach, it could unequivocally be demonstrated that all of these formulations contained new and recurrent peptaibols, i.e., peptaibiotics carrying an acetylated N-terminus, the C-terminus of which is reduced to a 1,2-amino alcohol. Their chain lengths, including the amino alcohol, were 11, 14, and 18 residues, respectively. Peptaibols were also to be the dominating secondary metabolites in plate cultures of the four strains obtained from four of the Trichoderma- based BCAs, contributing 95% of the UHPLC-UV/VIS peak areas and 99% of the total ion count MS peak area from solid media. Furthermore, species-specific hydrophobins, as well as non-peptaibiotic secondary metabolites, were detected, the latter being known for their antifungal, siderophore, or plant-growth-promoting activities. Notably, none of the isolates produced low-molecular weight mycotoxins.

    Mae Moh is a risky area for arsenic contamination caused by the effluent from biowetland ponds in Mae Moh lignite-fuelled power plant. The objective of this study was to investigate the arsenic concentrations of Mae Moh biowetland ponds and determine the main factors which are important for arsenic phytoremediation in the treatment system. The result revealed that arsenic concentrations in the supernant were in the range of less than 1.0 microg As L(-1) to 2.0 microg As L(-1) while those in the sediment were in the range of 25-200 microg As kg soil(-1). Both values were below the Thailand national standard of 0.25 mg As L(-1) for water and 27 mg As kg soil(-1) for the soil. Arsenic accumulation in the biomass of 5 aquatic plants at the biowetland ponds ranged from 123.83 to 280.53 mg As kgPlant(-1). Regarding the result of regression analysis (R (2) = 0.474 to 0.954), high concentrations of organic matter and other soluble ions as well as high pH value in the sediment could significantly enhance the removal of soluble arsenic in the wetland ponds. From the regression equation of accumulated arsenic concentration in each aquatic plant, Eichhornia crassipes (Mart.) Solms. (R (2) = 0.954), Ipomoea aquatica Forsk. (R (2) = 0.850), and Typha angustifolia (L.) (R (2) = 0.841) were found to be preferable arsenic removers for wastewater treatment pond in the condition of low Eh value and high content of solid phase EC and phosphorus. On the other hand, Canna glauca (L.) (R (2) = 0.749) appeared to be favorable arsenic accumulator for the treatment pond in the condition of high Eh value and high concentration of soluble EC.

    This study investigated the influence of the internal structure of amylopectin on annealing (3h, 24h) of starches from four different types of amylopectin (Bertoft, Koch, & Aman, 2012; Bertoft, Piyachomkwan, Chatakanonda, & Sriroth, 2008). Regardless of the starch source and incubation time, annealing significantly increased the onset gelatinization temperature (To) and narrowed and deepened the amylopectin endotherm. However, the extent of the change in the melting temperature (Tm) and the enthalpy of gelatinization (ΔH) differed among the types. In terms of the To and Tm, starches from type 1 (oat, rye, barley, and waxy barley) showed the most significant response to annealing. The Tm of starches belonging to type 2 (waxy maize, rice, waxy rice, and sago) remained unchanged after 3h of annealing. Type 1 and type 2 starches with the lowest gelatinization temperatures showed the greatest increase in melting temperature after annealing. However, type 3 (tapioca, mung bean, and arrowroot) and type 4 (potato, waxy potato, canna, and yam) starches were not in line with these observations. Instead, starches from type 3 and type 4 showed a pronounced increase in the ΔH. The inter-block chain length (IB-CL) (distance between tightly branched units within a cluster) correlated positively (r=0.93, pannealing. These data indicate that a short IB-CL affects the optimum registration of double helices within the crystalline lamellae. The relationship between the gelatinization parameters before and after annealing suggests that type 1 and 2 starches might possess a high number of unpacked double helices (type 1>type 2) compared to other types. Longer IB-CLs, which facilitate the parallel packing of splayed double helices, and the lengthening of double helices likely increased the ΔH in type 3 and type 4 starches. It is concluded that annealing can be used as a probe for visualizing the organization of glucan chains (alignment of double helices/degree of perfection) within

    5-Substituted 4-oxo-2-thioxo-1,2,3,4-tetrahydropyrimidine were synthesized by interaction of 4-oxo-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-sulfonylhydrazide with some aldehydes to give the corresponding Schiff-bases, which after cyclization gave corresponding thiazolidinones. For some of the thiazolidinones, Mannich bases reaction was carried out. All the derivatives were tested for their possible inhibitory effect on Schistosoma mansoni cercarial elastase (CE). Only, N-(4-methylbenzyledine)-4-oxo-2-thioxo-1,2,3,4-tetrahydropyrimidine-5-sulfonylhydrazide was found to have potent inhibitory effect on the CE activity with IC50 = 264 microM. Upon its use as a paint for mice tails before infection with S. mansoni cercariae, the compound formulated in jojoba oil caused a significant reduction (93%; P-value = 0.0002) in the worm burden. IgG & IgM in mice sera were measured by using several S. mansoni antigens by ELISA. Sera from treated infected mice (TIM) 2, 4, and 6 weeks (W) post infection (PI) showed 1.2 folds lower, 1.2 folds higher, 1.7 folds lower IgM reactivity against soluble cercarial antigenic preparation (CAP), respectively, when compared with sera collected from infected untreated mice (IUM). Sera from TIM 2, 4, and 6WPI showed 1.3, 1.6, and 1.7 folds higher IgG reactivity, respectively against CAP than the IgG reactivity from IUM. Sera from TIM 2, 4 and 6WPI showed 1.5, 1.2 folds lower and 1.4 folds higher IgM reactivity, respectively against soluble worm antigenic preparation (SWAP) when compared with sera collected from IUM. Sera from TIM 2, 4, and 6WPI showed 1.4, 1 folds lower and 1 fold higher IgG reactivity, respectivley to SWAP when compared with sera from IUM. Sera from TIM 2, 4, and 6WPI had generaly lower IgM and IgG reactivities against soluble egg antigen (SEA) when compared with sera from IUM.

    Le complicanze vascolari dopo il trapianto renale non sono comuni, e nella maggior parte dei casi si presentano nel periodo post-trapianto precoce. Gli pseudoaneurismi arteriosi coinvolgono l’anastomosi arteriosa del rene trapiantato e nella maggior parte dei casi riconoscono una eziologia micotica. Una donna di 62 anni, che è stata sottoposta otto mesi prima ad un trapianto renale, presentava un vago dolore in fossa iliaca destra. L’ecografia del rene trapiantato dimostrava la presenza di un’area ipoecogena in corrispondenza dell’ilo renale, che all’ecocolordoppler appariva riccamente vascolarizzata. La tomografia computerizzata confermava la diagnosi di pseudo-aneurisma anastomotico di 33 mm di diametro, coinvolgente l’arteria del rene trapiantato. La paziente è stata dunque sottoposta a intervento chirurgico di aneurismectomia, con successivo bypass fra arteria renale del rene trapiantato e arteria iliaca interna. La continuità arteriosa iliaca è stata dunque ristabilita attraverso un by-pass iliaco-esterno-femorale comune in vena safena invertita. L’ecocolordoppler intraoperatorio dimostrava la corretta perfusione del graft renale e la corretta pervietà del by-pass iliacofemorale. Il decorso post-operatorio è stato privo di complicanze significative, eccettuata una linforrea inguinale risolta spontaneamente in 22a giornata post-operatoria. Sei mesi dopo la procedura, la paziente è in ottime condizioni generali, con una funzionalità renale conservata e una corretta pervietà del by-pass iliacofemorale. Lo pseudo-aneurisma dell’arteria renale rappresenta una rara complicanza del trapianto renale. Nella maggior parte dei casi riconosce una eziologia micotica, spesso a causa di contaminazione diretta del graft durante le procedure di prelievo o conservazione dell’organo. Il trattamento è molto complesso, e in molti casi richiede l’espianto del graft. Tuttavia, in alcuni casi selezionati, è possibile eseguire il trattamento dell

DNA manipulation plays an important role in un-derstanding the function of genes and in constructing novel engineering bacteria according to requirement. DNA manipulation involves modifying the autologous genes and expressing the heterogenous genes. Two alternative approaches, using electroporation linear DNA or recombinant suicide plasmid, alow a wide variety of DNA manipu-lation. However, the over-expression of the desired gene is generaly executed via plasmid-mediation. The current review summarizes the common strategies used for geneticaly modifyingE. coli andC. glutamicum genomes, and discusses the technical problem of multi-layered DNA manipulation. Strategies for gene over-expression via inte-grating into genome are proposed. This review is intended to be an accessible introduction to DNA manipulation within the bacterial genome for novices and a source of the latest experimental information for experienced investigators.

Generaly, high-end brands and auto brands which put emphasis on individualization pay more attention to the inheritance of car styling. Inheritance of car styling can be presented on the whole appearance of car bodies and some family styling languages on parts of car bodies such as air-inlet griles. On the other hand, variations of car styling can be presented on three aspects which are folowing popularity, using brand-new family styling languages and varying slightly family styling languages. In the process of car regenerations, auto brands should handle the relation of inheritance and variations of car styling according to their brand positioning, strategy planning and the change of market environment.

    Full Text Available Total urinary neutral 17-steroids were determined in normal and in castrated horses. One liter of a 15-26 hours urine collection was hydrolysed by refluxing with 10% HC1 (v/v for ten minutes and extracted with peroxyde-free ethyl ether. The extract was purified by washing with saturated NaHCO³ and KOH solutions. One half of the crude neutral fraction was fractionated with Girard's "T" reagent . The Zimmermann reaction was performed both in the ketonic and in the crude neutral extracts, using alcoholic 2.5N KOH and a 60 minutes period for the colour development in the dark. Optical density measuments were made in a grating Coleman Universal Spectrophotometer at 420 mµ and 520mµ; for the crude neutral fraction a colour correction equation was applied. The aliquot fraction used for colorimety was adjusted for keeping optical density measurements within the range 0.2 to 0.7. Androsterone (mp. 184-184.5°C with an absorption maximum at 290.5 mµ (Beckman Model DU Spectrophotometer was used as a reference standard. Table I, ilustrates the results obtained. At the 0.05 probability level there is a significant difference among castrated and normal group means (Fischer's "t" test. when were used the data obtained from the ketonic fractions; in spite of the use of a colour correction applied for inespecific chromogens, the same results could not be obtained with the crude neutral fractions, Since Girard's reagent fractionation is generaly accepted as the best method for correcting the inespecific chromogen interference in the determination of the 17-ketosteroids by the Zimmermann reaction, we emphasize the value of the results obtained with the ketonic fractions. From these results it appears, as occurs in others mammals, that castrated horses show a lower level of urinary 17-ketosteroids excretion than the normal horses. The significance of the horse testis contribution for the neutral urinary steroid metabolites is discussed. Since horse urine has a

    Obiettivo: La patologia diverticolare acuta è attualmente molto frequente nei paesi occidentalizzati. L’aumento costante del numero dei pazienti ricoverati nelle Unità operative di Chirurgia per il trattamento d’Urgenza sta portando alla necessità di individuare nuove Classificazioni e Scores per il corretto e razionale trattamento medico e chirurgico, anche in relazione all’assenza di linee guida ufficiali. Metodi: Si tratta di uno studio retrospettivo che prende in considerazione tutti i pazienti ricoverati presso il nostro Dipartimento, con diagnosi di diverticolite acuta perforata, nel periodo di tempo compreso tra giugno 2010 e marzo 2015. Risultati: Nel nostro studio 41 pazienti sono stati trattati conservativamente. I restanti 58 pazienti sono stati sottoposti ad intervento chirurgico: 25 con procedura di Hartmann, 29 con intervento di resezione e consensuale confezionamento di anastomosi senza ileostomia di protezione, 3 pazienti sono stati sottoposti a riparazione diretta della lesione diverticolare (rafia) e 2 a lavaggio peritoneale laparoscopico con posizionamento di drenaggio. Di questi ultimi due pazienti, uno è stato dimesso dopo 7 giorni in buone condizioni cliniche generali ed uno è stato poi sottoposto a resezione e confezionamento di anastomosi. Abbiamo correlato i pazienti suddividendoli nei vari gruppi Hinchey modificati e sovragruppi, associandoli ai diversi trattamenti, identificandone i fattori di rischio, l’ASA score e le complicanze. Discussione: L’utilizzo di nuove tecnologie, come la TC, si sta rivelando molto utile per la diagnosi delle diverticoliti perforate. Il loro trattamento è invece ancora piuttosto dibattuto: per i pazienti Hinchey I e II è, tendenzialmente conservativo, a meno di fattori concomitanti che ne pregiudichino l’andamento clinico. I pazienti Hinchey III e IV sono di competenza chirurgica. Il trattamento preferenziale è la procedura di Hartmann ma negli ultimi anni la resezione con consensuale

    Institute of Scientific and Technical Information of China (English)

    2015-01-01

    Since Confucius’and Plato’s ideas of the best regime decisively shape their conceptions of poetic education,a more meaningful comparison of their conceptions of poetic education must be based on that of their ideas of polity.Their ideal political order,as far as its fundamental principle is concerned,can be defined as a kind of aristocracy based upon hierarchical distinctions of humanity. Poetic education in Confucius and Plato is,therefore,politically moral education required by that aristocracy.Although this classical moral education,in general,is aimed at a principle of mean or moderation,there are nonetheless significant differences between Confucius’notions of education practiced in The Book of Songs and those of Plato’s in poetry,because benevolence,which is morally underlying Confucius’ideal political constitution,bears fundamental differences from the absolutely public spiritedness required by Plato’s ideal polis in speech in his Republic .%由于孔子和柏拉图的政制观念对其诗教观念具有决定意义,只有基于孔子与柏拉图政制观念的异同,才能更有意义地比较两者诗教观的异同。就根本理念而言,孔子和柏拉图的理想政治秩序都可以被归结为基于人性差序的贤良政制,因此,诗教在孔子和柏拉图那里都表现为贤良政制所要求的政治德性教化。但是,尽管上述德性教化在孔子和柏拉图那里都以中道或节制等原则为重要旨归,由于作为孔子理想礼制道德基础的“仁”与柏拉图理想城邦所要求的绝对公共德性之间存在重要差异,孔子之《诗》教观念与柏拉图的诗教观念之间必然存在重大差异。

    The High Resolution Imaging Science Experiment (HiRISE) on the Mars Reconnaissance Orbiter (MRO) has acquired more than 9,500 images of Mars with 8.2 Terapixels of data, covering 0.6% of the surface. Images are generaly 5-6 km wide with 3-color coverage over the central 20% of the image swath, and their resolutions usually range from 25-60 cm/pixel. More than 1,000 stereo pairs have been acquired and 50 digital terrain models (DTMs) completed; these data have led to some of the most significant science results. New methods to measure and correct distortions due to pointing jitter facilitate topographic and change-detection studies at sub-meter scales. There are recent results concerning Noachian bedrock stratigraphy, fluvially-deposited fans in craters and in or near Valles Marineris, groundwater flow in fractures and porous media, quasi-periodic layering in polar and non-polar deposits, tectonic history of west Candor Chasm, geometry of clay-rich deposits near and within Mawrth Vallis, dynamics of flood lavas in the Cerberus Palus region, new evidence for pyroclastic deposits, columnar jointing in lava flows, recent collapse pits, evidence for aqueous modification of well-preserved impact craters, newly-discovered large rayed craters, and glacial and periglacial processes including candidate pingos and "gullies". We are particularly interested in ongoing processes such as those driven by the wind, impact cratering, avalanches of dust and/or frost, relatively bright deposits on steep gullied slopes, and the dynamic seasonal processes over polar regions. In the middle latitudes, 5 very recent impacts (at least 3 and perhaps all 5 occurred in 2008) have exposed shallow ice. We are also especially interested in the oldest exposed rocks, the Noachian megabreccia commonly found in the central uplifts of large craters in or near Noachian (>3.8 Ga) terrains; near the rims of large basins, such as Isidis; and in deep exposures, such as the floor of Uzboi Valles and in

    Full Text Available We report on the clinical and EEG features of 15 patients with the syndrome of "continuous spike waves during slow wave sleep" (CSWSS. The differential diagnosis of CSWSS includes benign epilepsy of childhood with centro-temporal spikes, and Landau-Kleffner and Lennox-Gastaut syndromes. We found normal CT and MRI features in 6 cases, periventricular leukomalacia with and without diffuse brain atrophy in 4 cases and hydrocephalus in 1 case. There was no association between specific neurological findings and CSWSS. Nine of our cases had relatively focal discharges, like some cases from the literature. The occurrence of CSWSS appears to be age-related, generaly between the ages of 5 to 12 years, with a strong temporal relation to the neupsychological deterioration in its nature, severity and prognosis. We believe that this striking disorder has been overlooked and that routine sleep EEG studies on epileptic children may disclose additional cases of CSWSS.Relatamos as características clínicas e eletroencefalográficas de 15 patientes com a síndrome de ponta-onda contínua do sono não-REM (POCSNR. O diagnóstico diferencial da POCSNR inclue a epilepsia benigna da infância com pontas centro-temporais e as síndromes de Landau-Kleffner e Lennox-Gastaut. Encontramos TC e RNM de crânio normais em 6 casos, leucomalácia periventricular em 4 e hidrocefalia em 1. Não houve associação de achados neurológicos específicos e a POCSNR. Nove dos nossos casos tinham descargas relativamente focais, como alguns casos da literatura. A ocorrência da POCSNR parece ser idade-dependente, geralmente entre 5 e 12 anos, com forte relação temporal à deteriorização neurocognitiva, em sua natureza, severidade e prognóstico. Acreditamos que esta síndrome tem sido pouco diagnosticada e que a realização rotineira de EEG em sono em crianças epilépticas possa revelar novos casos de POCSNR.

    Obiettivi: gli obiettivi generali della ricerca sono stati: stimare un eccesso di rischio di insorgenza di gastroenterite a seguito di attività di balneazione o consumo di prodotti ittici nel mare Adriatico; misurare nuovi parametri microbiologici di inquinamento marino.

    Metodi: sono stati condotti i seguenti studi: 1 caso controllo; 2 uno studio di prevalenza (beach survey per descrivere la frequenza di alcune patologie (dell’orecchio, delle vie aeree superiori, della cute rispetto alla balneazione o meno; 3 identificazione di nuovi patogeni nelle acque di balneazione (quali virus o Cryptosporidium parvum.

    Risultati: l’analisi dei fattori di rischio nello studio caso controllo non ha evidenziato un aumento di gastroenterite associata a balneazione. Gli episodi gastroenterici osservati nei casi erano prevalentemente sostenuti da Salmonella sp. e la modalità di infezione era legata ad alcuni alimenti quali la maionese. Il risultato principale dello studio di beach survey è stato che la balneazione nel mare Adriatico non è associata ad un aumento significativo di patologie serie, quali gastroenterite acuta.

    Tuttavia, è stato possibile evidenziare un aumento di rischio statisticamente significativo per forme morbose lievi, quali congiuntivite e dermatite aspecifica, fra chi ha fatto il bagno in mare e chi no. Tale aumentato rischio è stato soprattutto osservato nei bambini e ragazzi al di sotto di 15 anni. I risultati di microbiologia sperimentale dimostrano il ruolo svolto dalle acque marine quale pabulum idoneo alla sopravvivenza delle oocisti di C. parvum. Sono stati validati protocolli di diagnostica molecolare per l’identificazione di enterovirus, rotavirus e reovirus nelle acque di balneazione.

    Conclusioni: l’epidemiologia può contribuire a studiare i rapporti fra balneazione e salute all’interno di una visione generale di salute

    Full Text Available Paolo Solla, Antonino Cannas, Francesco Marrosu, Maria Giovanna MarrosuMovement Disorders Center, Institute of Neurology, University of Cagliari, Cagliari, ItalyAbstract: Parkinson disease (PD is a neurodegenerative disorder characterized by 3 cardinal motor symptoms: resting tremor, rigidity, and bradykinesia. Since its introduction 40 years ago, levodopa has represented the gold standard for dopaminergic stimulation therapy in patients with PD. Levodopa is routinely combined with a dopa-decarboxylase inhibitor (DDCI to prevent the conversion of levodopa into dopamine in peripheral circulation. However, up to 80% of patients treated with continuous levodopa manifest the onset of disabling motor complications capable of producing an adverse effect on quality of life as the disease progresses. In recent years, a new, safe, and efficacious armamentarium of treatment options has been provided by the marketing of the catechol-O-methyltransferase (COMT inhibitor, entacapone, a peripheral blocker of dopa to 3-0-methyldopa metabolism, which increments levodopa brain availability. When administered with levodopa, entacapone conjugates the rapid onset of levodopa-induced effects with a protracted efficiency, thus providing additional benefits to classic levodopa treatment by increasing “on” time in fluctuating PD patients, and theoretically providing a more continuous and physiological-like stimulation of dopamine receptors implying a reduced risk of motor complications. In this context, the use of a single administration of combined ­carbidopa/levodopa/entacapone (Stalevo® in the treatment of PD affords clinical improvements similar to those obtained by 2 separate tablets (ie, levodopa/DDCI and entacapone, although the former produces a more positive effect on quality of life than the latter. Additionally, the STalevo Reduction In Dyskinesia Evaluation (STRIDE-PD study was designed with the aim of demonstrating that the combination of levodopa

    Triazophos (TAP) is a widely used pesticide that is easily accumulated in the environment due to its relatively high stability: this accumulation from agricultural runoff results in potential hazards to aquatic ecosystems. Constructed wetlands are generally considered to be an effective technology for treating TAP polluted surface water. However, knowledge about the biological mechanisms of TAP removal is still lacking. This study investigates the responses of a wetland plant (Canna indica), substrate enzymes and microbial communities in bench-scale horizontal subsurface-flow constructed wetlands (HSCWs) loaded with different TAP concentrations (0, 0.1, 0.5 and 5 mg·L{sup −1}). The results indicate that TAP stimulated the activities of superoxide dismutase (SOD) and peroxidase (POD) in the roots of C. indica. The highest TAP concentrations significantly inhibited photosynthetic activities, as shown by a reduced effective quantum yield of PS II (Φ{sub PSII}) and lower electron transport rates (ETR). However, interestingly, the lower TAP loadings exhibited some favorable effects on these two variables, suggesting that C. indica is a suitable species for use in wetlands designed for treatment of low TAP concentrations. Urease and alkaline phosphatase (ALP) in the wetland substrate were activated by TAP. Two-way ANOVA demonstrated that urease activity was influenced by both the TAP concentrations and season, while acidphosphatase (ACP) only responded to seasonal variations. Analysis of high throughput sequencing of 16S rRNA revealed seasonal variations in the microbial community structure of the wetland substrate at the phylum and family levels. In addition, urease activity had a greater correlation with the relative abundance of some functional microbial groups, such as the Bacillaceae family, and the ALP and ACP may be influenced by the plant more than substrate microbial communities. - Highlights: • Physiological responses of the wetland plant to triazophos

    芭蕉芋(Canna Edulis Ker)是一种很有潜力的淀粉作物,它可以在山地和低地种植。尽管如此,据我们所知,目前只有一个工厂在用它进行商业规模的生产。淀粉使用者对其性能所知的信息很少。本文介绍了在中国贵州省生产工业芭蕉芋淀粉的工艺。一般来说,农村小作坊将芭蕉芋制成粗淀粉。供应给工厂生产精淀粉。粗淀粉通常有杂质,因此有暗色的。工业上采用一套抽提器、分离机和化学漂白剂(次氯酸钙)工艺进行提纯,可以制得高质量淀粉。这种商品淀粉有其独特的性质,即其颗粒特别大、糊液清澈高度(1%淀粉在650nm处有47%的澄明度),凝胶热函比较高(26.78J/g)。用Brabender粘度测定仪,在低浓度(3.58%淀粉)与标准的浓度(6.00%淀粉)下测定的糊化性能,表现了不同的模式,这一点用快速粘度测定仪测定时也得到证实,其成胶性能很好,当用50%芭蕉芋淀粉和木薯淀粉混合时,也可以重复此性能。

    Full Text Available Abstract Pretrial arrangement in the Criminal Procedure Code is a strict rule with a clear limitation. One function of pretrial is to test the validity of the initial arrest and detention as a forced effort on behalf of legislation. Pretrial in the formulation of the Criminal Procedure Code is more directed at administrative oversight. In a pretrial ruling No. 04/Pid.Prap/2015/PN.Jkt.Sel., judges have intruded normative boundaries by extending the authority of a preliminary hearing object includes examining “determination of the suspect”, although not explicitly mentioned in the Criminal Procedure Code provisions. The problem in this research is “How is the existence of Criminal Pretrial Case Decision No. 04/Pid.Prap/2015/PN.Jkt.Sel., viewed from the aspect of justice and the rule of law?”. This research is a normative juridical approach method using the conceptual approach, case approach and the approach of legislation. Based on the findings, it was concluded that the examination in pretrial is a voluntair examination as an effort to actualize the procedural justice, but related  to a quo case, to realize substantial justice the judges act by entering the “determination of the suspect” as an element of the object of new norms in the series Article 77 letter a Criminal Procedure Code into a pretrial authority. This creates legal uncertainty, since it contradicts with the principle of Lex Specialis Derogat Legi Generalis, Noscitur a Sociis principle, Ejusdem Generis principle and the principle of Expressio Unius Exclusio Alterius. With the model of reasoning methods argumentum a'contrario as one of the construction methods of the law against Article 77 letter a Criminal Code, it is known that the “determination of the suspect” is not a pretrial object . The actions of judges had exceeded its authority, and the logic of the law of the judge in the formation of the new norm object element does not include extensive interpretation

    squalane generaly indicates hypersaline conditions of the seawater. Its occurrences in the Sancerre deposits are restricted underneath the C-isotope negative excursion and indicate a confined environment. This organic compound completely disappears with the anoxia, i.e. during and after the supposed methane hydrates release. The proxy Sr/Ca is discussed in terms of nannofossil assemblage and productivity. Crepidolithus crassus coccolith becomes the main calcareous contributor after the C-isotope excursion, relaying the Schizosphaerella punctulata calcareous dinoflagellate in both studied sites. The bulk carbonate, Crepidolithus-rich fractions, SEM spot chemical measurements and XRD analyses unambiguously indicates particularly high content in the carbonate lattice of this coccolith. Mechanisms enabling such bio- incorporation of unusual quantities of strontium into coccoliths are still misunderstood but a link with an increased productivity probably modified by differential growth rate (inferred by Sr/Ca ratio) and/or vital effect may be inferred. Moreover, high continental flux of Sr into the seawater, pinpointed by change in the Sr-isotope profile, might also be considered. These two observations within the Paris Basin must be completed by further biogeochemical studies in other realms.

    (quartz and calcite, this article shows the different analytical possibilities with a sample alone, with compensation for a pure diluent, with compensation for a single mineral and with compensation for a mineral in an artificial and a natural mixture (sedimentary rock. The changes undergone by the spectra are described, and calibration curves are plotted in each case. The data gathered are used to check the justified use of the absorption law for these solid-phase infrared analysis, involving a compensation, and hence the processing of the original spectra, with the maximum relative experimental error being no more than several percent in the most unfavorable cases. Within the limits of the detection of minerals having a set chemical composition and crystalline structure, the analysis of a mineral by its partial compensation may be of great importance for the major constituents of rocks because it enables analysis to be performed where too high a concentration would have made such analysis impossible heretofore. This compensation method is more delicate or even impossible for solid solutions or for any mineral with a variable chemical formula. Generaly speaking, the main constituents of sedimentary rocks can thus be quantified from a single spectrum by IR analysis which thus makes it possible to obtain a numerical definition of facies.

    BACKGROUND:Matrix metaloproteinases are now generaly considered to be able to degrade al extracelular matrices. Hypersecretion of matrix metaloproteinases or reduction in tissue inhibitors of matrix metaloproteinases leads to destruction of the dynamic balance of extracelular matrix. OBJECTIVE: To elucidate the role of matrix metaloproteinase-1 and tissue inhibitor of matrix metaloproteinase-1 in the pathogenesis and progression of intervertebral disc degeneration. METHODS:A total of 60 patients with intervertebral disc degeneration were included. Mild, moderate, and severe degeneration signals appeared on MRI imaging of the patients. Meanwhile, 20 patients with vertebral fracture, mainly cervical spine fracture, were selected as the control group. Venous blood samples were colected before the surgery; the intervertebral disc specimens were sequentialy colected. RESULTS AND CONCLUSION: Serum and tissue levels of matrix metaloproteinase-1 in patients with intervertebral disc degeneration were significantly increased compared with the control group (P 0.05). These results indicate that hypersecretion of matrix metaloproteinase-1 occurs in patients with intervertebral disc degeneration; however, the expression of tissue inhibitor of matrix metaloproteinase-1 is not correlated with intervertebral disc degeneration.%背景:基质金属蛋白酶现被公认为能降解所有的细胞外基质,基质金属蛋白酶分泌过多或金属蛋白酶抑制剂的分泌减少能破坏细胞外基质的动态平衡。目的:试图阐明基质金属蛋白酶1和金属蛋白酶抑制剂1在椎间盘退变的发病机制。方法:选择60例椎间盘退变患者,根据磁共振(MRI)检查结果分为椎间盘有轻度的退变信号、椎间盘中度抑制信号及椎间盘严重的退变信号3个亚组;对照组20例椎体骨折(颈椎为主)但椎间盘正常的患者。在术前收集静脉血液样品,随后收集病变的椎间盘组织。结果与结论:①椎

La BC2 è il solo esempio di architettura classificatoria analitico-sintetica completamente faccettata, aggiornata e coerentemente sviluppata, ma è poco usata al di fuori dell’Inghilterra ed è ancora priva di un'interfaccia web che possa rappresentare tutte le complesse relazioni semantiche del sistema. La sua struttura ha esercitato influenze sull'informatica, testimoniate dal progetto FATKS dell’University College London, che ha studiato l’impiego delle classificazioni analitico-sintetiche come base per l’indicizzazione delle risorse digitali.

    Full Text Available I beni archeologici sono anche una risorsa economica, ma tale definizione è insufficiente se posta in contrapposizione con il valore immateriale della cultura in sé, in mancanza del quale tutto perde valore, perché esso incide profondamente sulla qualità della vita.Ogni sito archeologico nasconde in sé le potenzialità di una condivisione di culture e prospettive e il rischio di nuovi steccati in nome di un’identità rivendicata con l’occhio rivolto al passato. Guardando con gli occhiali dello storico nella profondità del tempo ci vediamo immersi in un intreccio, dove l’identità non è più un dato statico da disvelare, ma una condizione dinamica, il frutto di un processo di esperienze condivise. L’archeologia è infatti uno strumento formidabile che contrasta l’oblio, rimotivando continuamente le finalità della conoscenza critica del passato, per ricostruire l’origine delle differenze tra le culture e afferrare la complessità del presente.L’archeologo deve assumersi la responsabilità di stabilire una nuova gerarchia delle informazioni. Non esistono scorciatoie quando in ballo è la conservazione della memoria storica del nostro Paese, ma la sua salvaguardia è parte di un progetto complessivo di attenzione alla qualità del vivere, rispetto alla quale l’archeologia può dimostrare di saper conciliare questa salvaguardia con gli interessi più generali della collettività. Prima di valorizzare occorre pensare se ne valga davvero la pena. Il ruolo progettuale degli archeologi dovrebbe fondarsi sulla capacità di interpretare ciò che resta del passato, di restituirgli un senso. Per questo la valorizzazione è una funzione sociale vitale, che identifica le capacità di una nazione di testimoniare la propria eredità culturale e di farla vivere manifestandosi a tutti i livelli pubblici, associativi, privati nei quali si articola la società civile. The economical value of the archaeological resources is insufficient when

    关于实践范畴的外延学界长期存在争议,两个基本倾向是泛化和狭化。外延的准确界定需要内涵的精确把握,在重新解读实践内涵的过程中,我们必须坚持两个原则:一是在哲学史中理解实践,二是把实践作为一个统一体进行研究。依此原则,我们的结论是:不是用物质或者精神规定实践,而是用实践规定物质和精神。实践是人类全部生活的基础,但是,不是所有人类活动都是实践。判断实践的标准是能动性和现实性的统一。在此基础上,依据马克思的《资本论》及其手稿为核心文本,我们对物质活动、交往活动和精神活动分别做了比较精确的实践界定,明确了它们的内涵和外延。西方存在主义马克思主义哲学家萨特的历史人类学中关于集合和群体的论述,以及当代中国化马克思主义哲学的一些成果给了我们重要启示。%The category of practice in Marxist philosophy in an important position is self - evident, but the connotation and extension of it is in a long - standing dispute. Two basic tendencies are the generalization and narrow. The accurate extension needs the exact defi- nition. In the interpretation of the connotation of practice, we must adhere to two principles : one is to understand the practice in the history of philosophy; the other is to take the practice as a unity. According to them, we not only reveal errors of the practice generali- zation theory and the practice narrow theory, but also through the practice connotation determine draw an important conclusion: not reg- ulate practice with material or spirit, but regulate material or spirit with practice. Practice is the foundation of all human life, but not all human activities are practice. The standard to judge practice is unity of the initiative and the reality.

The shelter used by the species was located between the outer wall and the flue of the central heating system. The maximum number of specimens observed at the same time was one male and two females. Some characteristic calls uttered by the male have been noticed. These consisted in several very loud shrill notes often given out in rapid succession. These calls have been heard mainly during the day and at sunset, amid the noise from the city and industries in the surrounding; they lasted about 30 seconds on average (up to 45. These calls were probably given out at times of maximum excitement, perhaps in the pre-mating phase. They were heard more frequently in spring (March-May but also in autumn (October-November. Flight generally occurred at temperatures no lower than 16 °C and from 25 to 60 minutes after sunset, after characteristic loud calls, and coming its habitual shelter. The presence of the European free-tailed bat in this spot may have been influenced by the source of heat represented by the flue, which supplied warmth during the winter months and, at the same time, by the trophic opportunities offered by the vast uncultivated fields in the area, with luxuriant herbaceous vegetation, scattered shrubs and trees, ditches, a few small cane thickets, flooded fields. The flue has not been activated since 1987, but the species has continued to live in the same place until 1590 (last sighting on March 1. The author excludes the presence of the species in the study site before 1983.

    This paper describes the eight-day August 2013 test campaign designed to investigate and demonstrate viability of using classical magnetoplasmadynamics to obtain a propulsive momentum transfer via the quantum vacuum virtual plasma. This paper will not address the physics of the quantum vacuum plasma thruster, but instead will describe the test integration, test operations, and the results obtained from the test campaign. Approximately 30-50 micro-Newtons of thrust were recorded from an electric propulsion test article consisting primarily of a radio frequency (RF) resonant cavity excited at approximately 935 megahertz. Testing was performed on a low-thrust torsion pendulum that is capable of detecting force at a single-digit micronewton level, within a stainless steel vacuum chamber with the door closed but at ambient atmospheric pressure. Several different test configurations were used, including two different test articles as well as a reversal of the test article orientation. In addition, the test article was replaced by an RF load to verify that the force was not being generated by effects not associated with the test article. The two test articles were designed by Cannae LLC of Doylestown, Pennsylvania. The torsion pendulum was designed, built, and operated by Eagleworks Laboratories at the NASA Johnson Space Center of Houston, Texas. Approximately six days of test integration were required, followed by two days of test operations, during which, technical issues were discovered and resolved. Integration of the two test articles and their supporting equipment was performed in an iterative fashion between the test bench and the vacuum chamber. In other words, the test article was tested on the bench, then moved to the chamber, then moved back as needed to resolve issues. Manual frequency control was required throughout the test. Thrust was observed on both test articles, even though one of the test articles was designed with the expectation that it would not

    论述了人工湿地污水处理技术的机制和优势,阐述了人工湿地的构建和污水处理研究进展,表明人工湿地的污水处理效率与污染物的种类和污染程度、人工湿地的类型、湿地植物种类、基质类型、水力停留时间和水力负荷等密切相关.在中国,典型人工湿地有3种类型,分别为垂直流人工湿地、潜流式人工湿地和表面流人工湿地,主要用于处理来自化粪池、养殖场、造纸厂、油田、煤矿、富营养湖泊以及城市生活等的污水.构建人工湿地常用的植物有芦苇(Phragmites austr alis)、香蒲(Typha orientalis)、美人蕉(Canna indica)、眼子菜(Potamogeton sp.)和金鱼藻(Ceratophyllum demersum)等,常见的基质成分为砾石、沸石、沙子、土壤或炉煤渣等.通过系统总结中国人工湿地在污水处理过程中的研究进展和应用实例,认为建立人工湿地去除污染物具有良好的应用前景,今后应该进一步加强人工湿地的基础理论研究,进一步推广人工湿地的应用.%This paper presents the mechanisms and advantages of the constructed wetlands and indicates the research situation of the wetland construction and disposition of sewage by the constructed wetlands. It shows that many factors such as the components and levels of pollutants, the types of constructed wetlands, the categories of its plants and fillers, the hydraulic retention time as well as the load of hydropower can influence the efficiency of the constructed wetland. In China, there are three major types of constructed wetlands: vertical flow constructed wetland, subsurface flow constructed wetland and surface flow constructed wetland. These constructed wetlands are mainly used for treating the sewage from cesspit, nursery, paper mill, oil and coal mine, eutrophic lake and city life. During the construction course of wetlands, reed, cattail, herb of distinct pondweed and ladder brake are chosen as the dominating plants

    微生物在人工湿地污水净化过程中发挥着重要作用,微生物生物量碳是微生物的重要表征之一.为探讨人工湿地土壤微生物量碳与污水净化效果的关系,以表面流人工湿地为研究对象,分别研究了不同植物人工湿地土壤微生物生物量碳和净化效果的时空变化及其相关性.结果显示,4种植物湿地表层(0-5 cm)微生物生物量碳极显著高于深层(15-20 cm)的测量值(P<0.01).人工湿地污染物去除效果与微生物生物量碳具有相同的季节变化规律,都呈单峰型的季节格局,夏秋季较高,冬春季较低.微生物生物量碳与人工湿地COD、BOD5和TN的去除呈显著正相关(P<0.05).水鬼蕉湿地具有较高的微生物生物量碳,而污染物去除率一般较低,这表明不同湿地微生物生物量碳与污染物去除率的相关性呈现不确定性.%Soil microorganisms are involved in all the biochemical processes which occur in soils, and they play a vital role in wastewater purification. Microbial biomass carbon is an important indicator of soil fertility, so we guess it is probably closely related to wastewater purification. For understanding whether relationship between nutrient removal rates and microbial biomass carbon existed, monoculture constructed wetlands of four plant species (Ph rag mites australis Trin. ex Steud., Hymenocallis littoralis (Jack.) Salisb., Canna indica Linn., Cyperus flabelliformis Rottb.) were built, and during a 2-month period, microbial biomass carbon and nutrient removal rates were measured. The results indicated that microbial biomass carbon in surface soil (0-5 cm) was significantly higher (P<0.01) than that in the deeper soil (15-20 cm). Both microbial biomass carbon and nutrient removal rates were higher during summer and autumn and lower during spring and winter. The removal rates of COD, BOD5 and total nitrogen were significantly correlated with microbial biomass carbon (P<0.05). In addition

    Five identical subsurface horizontal flow constructed wetlands ( SHFCWs) with different plants were constructed to treat slightly polluted river water under field conditions. The changes of pH, DO and ORP between influent and effluent were monitored, and also the impact of temperature on purification efficiencies was studied. Results showed that there were almost no differences between influent and effluent to DO in all five SHFCWs. Except wetland planted with Canna indica, there was a similar situation to pH in the rest of four wetlands. Compared with ORP of influent, ORP of effluent increased in planted wetlands. Removal rates of pollutants in planted wetland were higher than that of blank wetland, and the removal efficiencies of NH4+ -N, TN and CODMn increased with temperature increasing, which could reach to 90% , 50% and 20% , respectively. But removal efficiency of TP had no obvious change, varied from 30% to 60% in planted wetlands. The results of correlation analyses showed that there were significant correlations between temperature and removal of NH4+ -N and TN. The correlation between temperature and removal of CODMn was poor for low CODMn in influent. Because particulate phosphorus (PP) was the main form in all sorts of phosphorus removal, there was almost no correlation between removal of TP and temperature.%为了探讨潜流人工湿地对微污染河水的净化效果,在野外条件下构建潜流人工湿地,分析了湿地中pH、氧化还原电位(ORP)和DO的进出水变化,考察了湿地中污染物的净化效果,探讨了温度对湿地净化效果的影响.各湿地进、出水DO浓度相差不大;除美人蕉湿地外,其余湿地出水pH较进水变化较小;植物湿地出水ORP较进水均有所增大.植物湿地对污染物的去除效果均优于空白湿地,且随着气温的升高,NH4+-N、TN和CODMn的去除率逐渐增加,去除率分别可达90%、50%和20%.TP去除率却未随温度发

    Screening of plant species were carried out for establishing an ecosystem for retention and purification of soil infiltration water and surface runoff in Xiangtan manganese polluted area. The results obtained from a five month plant growth period indicate that mushroom grass had a very low survival rate while Arundo donax var. versicolor and Acorus calamus Linn had a negative value in its biomass increment. In comparison, the other nine plant species, Thalia dealbata, Boehmeria, Canna warscewiezii A. Dietr, Phragmites australis, Typha orientalis Presl, Pontederia cordala, Nerium oleander, Pontederia cordata, Sofistem bulrush and Iris germanica grew well in the manganese polluted sites. The manganese contents in shoots of the nine plant species were all more than 1000 mg/kg and their zinc, copper and cadmium contents were also relatively high, with the ratio of the metal content in above-ground tissues to that in roots being greater than 1. In contrast, the above-ground tissue to root ratio of zinc, copper, manganese and cadmium contents in A. calamus and that of zinc, copper, and cadmium contents in A. donax var versicolor were lower than 1, suggesting that the metal accumulation in roots due to weak heavy metal transfer abilities of these species had led to poisoning effects on the pant growth. The highest manganese uptake in above-ground tissues of Boehmeria reached 217.8 mg per plant. The next uptake value was given by T. dealbata, Boehmeria, followed in turn by C. warscewiezii, Dietr, P. australis, P. cordata and S. bulrush.%为建立锰污染土壤渗漏液和径流收集处理系统,在湘潭锰矿废弃地开展了植物筛选试验.5个月植物生长的试验结果表明,香菇草成活率低,花叶芦竹、菖蒲生长量下降,而再力花、苎麻、紫叶美人蕉、芦苇、香蒲、夹竹桃、梭鱼草、水葱和德国鸢尾长势良好,其地上部分锰的含量多高于1 000 mg/kg,锌、铜、镉的含量也相对较高,锰含量地上

    retest study with 115 participants, the structure of off-line metacognitive regulation was confirmed. In Study 2, hierarchical linear regression and hierar- chical logistic regression were conducted to examine the criterion-related validity of the off-line regulation questionnaire. The results showed that managers were different from common staff in particular regulation factors. Managers have higher generali- zing level than others in sales departments, while managers in support department have higher awareness level than others. But on the other hand, for the common staff, the level of off-line metacognitive regulation failed to predict employees'performance in sales depart- ment. However, for the staff in support department, the level of global-planning predicted the creative activities reversely. Based on the results, we suggest that the off-line metacognitive regulation questionnaire has good psychometric quality, and the procedures of admin- istrating and scoring are objective and standardized. It can be applied to business practices such as personnel selection and promotion%离线元认知调节指脱离具体任务情境后,个体在整体层面对自身活动的规划、管理、归纳反省并重新评价的过程。与在线元认知调节相结合,可以使元认知对行为的调节作用得到更加完整有力地发挥。本研究探索了离线元认知调节的测量学结构,开发出相应的测量工具,并且在职业测评领域通过实践检验。研究一编制离线调节量表,对离线元认知调节结构进行探索,得到全局规划、洞察力和整合概化三个维度;研究二对工具的效度进行实证检验,通过层次Logistic回归分析,发现公司中层领导与普通员工在离线调节水平上存在差异,验证了该工具的实证效度。研究结果证明离线调节量表具有较好的心理测量学品质,可以应用于相关的实践领域。

    Full Text Available La storiografia incentrata sul tema della Cassa per il Mezzogiorno è molto ampia e si sviluppa in relazione non solo alle questioni generali riguardanti l’intervento straordinario, ma anche alle molteplici forme di articolazione settoriale e territoriale dell’iniziativa pubblica per la ripresa e lo sviluppo del Sud. Una ricostruzione puntuale delle vicende della Cassa, che per oltre un quarantennio– anche se con diversità di impostazione nelle varie fasi –ha operato come strumento delle strategie per lo sviluppo del Mezzogiorno, richiede un impegno molto approfondito. Tuttavia, anche senza effettuare una dettagliata cronistoria dell’attività dell’Ente, si può ricomporre una visione d’insieme, attraverso l’interpretazione di un modello di intervento pubblico collegato strettamente agli eventi economici concreti e all’andamento dei processi di industrializzazione che hanno interessato i territori meridionali.La scelta di una prospettiva di lungo periodo, imperniata sull’analisi dell’intervento straordinario nel suo complesso, ha permesso un giudizio più equilibrato su tutta l’epoca dell’azione “aggiuntiva” dello Stato per il recupero del divario meridionale, superando eccessive semplificazioni nella valutazione di quell’esperienza e confutando pareri sommari sui suoi risultati, spesso privi di fondamento. Al tempo stesso, una visione ampia ha fatto emergere un percorso in grado di associare il caso della Cassa per il Mezzogiorno, controverso e difficile, ma considerato anche un modello tra i più avanzati a livello internazionale, a un tema di grande importanza, come quello delle politiche di sviluppo adottate per affrontare i problemi dell’arretratezza economica e per avviare a soluzione i dilemmi del dualismo.L’analisi effettuata ha provato l’esistenza di un indiscutibile progresso economico nel periodo della golden age. Durante quell’epoca di prosperità non solo si realizzò un notevole avanzamento

Tale esperienze ha prodotto la realizzazione di un “contenitore nuovo”, terzo, una nuova area di intervento che si colloca nel contesto del laboratorio emozionale/espressivo. Vengono descritti stimolo/proposta, contesto e relazione terapeutica come elementi specifici del setting, i quali sono a loro volta condizionati da elementi più generali che entrano in gioco negli interventi riabilitativi, cioè l’elemento emotigeno e quello ecologico. Il laboratorio espressivo diventa contesto per l’intervento sulla cognitività e sulla comunicazione con possibilità di utilizzo di diversi registri relazionali e comunicativi, con pazienti in una condizione clinica che varia dallo stato vegetativo alla disabilità moderata fino alla grave disabilità. Infine, vengono descritti due casi che esemplificano il metodo d'intervento integrato tra le tecniche sanitarie e quelle della comunicazione teatrale.

    is easy to spread and distribute among non-technical end-users. This app will help final users to carry out a standard monitoring procedure, in a quick way. All data (photographs, site characteristics, kind of debris, waypoints) will be properly captured and semi-automatically registered on a separate electronic spreadsheet. SeaCleaner app can be provided to environmental associations, marine parks, volunteers and its easy approach will allow us to obtain standardized and safe data, upcoming from an increasing number of points, which will be acquired in situ and then saved on a dedicated remote database. Citizen participation in scientific programs, already experienced in the field of astronomy [9] has been effective also in other scientific fields, both from the scientific and social point of view, since it brings people closer to science and fills the gap between who produces science and technology and who benefits from it ("citizen science") [10, 11]. SeaCleaner is ready to be used during the school year 2013/2014 to test its validity and usefulness. Further internships and collaborations between ISMAR and educational institutions, will allow us by the end of April 2014 to show the first dataset processed in this experimental phase. It is worth to highlight the active involvement of young people in this project and its effectiveness as a tool for raising awareness on environmental issues and orientating young people towards scientific careers.

    emotional incontinence have also been used, although less frequently. At the present, specific pathophysiological mechanisms of this disorder are still not clear. Insults that can lead to it are widely spread in the brain, but generaly they involve frontal cortex, the limbic system, the brainstem, the cerebellum and the underlying white matter that interconnect these networks. The most important differential diagnosis is depression. Nowadays, the available pharmacological therapies are based on selective serotonin reuptake inhibitors, tricyclic antidepressants, and, less often, dopaminergic agents. AVP-923 is a new compound that has been researched as a possible future specific treatment. DISCUSSION: Although IEED has long been recognized, even under diverse nomenclature, it remains underdiagnosed. Considering the deleterious effects of this disorder on social, occupational and familiar functionning of the affected patient, its recognition and accurate procedure are decisive to allow an improvement on patient's quality of life.

    Full Text Available The past of the scientific works of administration methods is quiteold. The struggle of finding out the best one by examining politicalsystems comperatively were not only limited with the past. It has beencarried on until today. As well as the works that have been performed inWest since the Ancient Greek Period, The Islamic World have submittedmany precious works in aforementioned topic. One of those whosubmitted precious works for political theory and politic systemclassification was Ibn Khaldun. He, with the light of his experience andobservations as someone who have taken part in politic life itself, hasexamined politic systems that could have been considered as beyondfrom his era. While the politic system classification has decreased tominimum with the theoratic thought came into prominence in themiddle age of the west, In Islamic World, Researching the politicalsystems which have been submitted by Ibn Khaldun without dependingon the absolute theoratic thoughts keeps this essay valuable. In thisrespect, the very place of Ibn Khaldun in social sciences is consideredprimarily. Afterward, The concepts of State, Relationship andPresidency-Estate which are irrevocable for his politic theory areelaborated. Finally, Politic system classification of Ibn Khaldun, Thebasic contect, is studied generaly. Ibn Khaldun bisects them astheoratic based system and Estate based system whilke secting politicalsystems. He also generalizes Estate based policy in two main topics asabsolute estate and politic estate. What Ibn Khaldun named andidealized administration method as a theoratic based policy isCaliphate or Imamate. Yönetim şekilleri ile ilgili bilimsel çalışmaların geçmişi oldukça eskidir.

    The secondary forest, as an integral part of Karst forest ecosystem,ecosystem, may be the future of a forest. The soil organic carbon is an important pan of the soil organic matter and its content has a major impact on soil biological activities and is also an important indieator of the soil fertility To understand the offects of soil organic carbon on soil hiological activities, three sample plots are taken, including a shrub, a Ligustrum lucidum forest and a pine forest and they are compated with the tilled field in the suburbs of Guiyang City during the sampling time (June, 2008-May, 2009). The data show that the shrub is characteterized by low substate carbon utilization weak biochemical processes and less available nutrients of plants and nmicrobes hased on per gram soil organic carbon, although with the highet soil organic carbon among the sample plots. The Ligustrum lucidum forest is marked by high nitrogen cycle rote, rich in denitrificauon enzyme and serious gaseous nitrogen loss, while, the pine forest is charactorized by high decomposition speed and strength.high soil nicrobial and enzyme activitics, strong soil biochemical processes and low gaseous nitrogen loss based on per gram soil organic carbon. Generaly speaking, the organic carbon content limits the size of soil microbial communities, affects soil enzyme activities in spurbs influences the microbial nitrogen conversion rate and organic matter decomposition rate indirectly but has no significant effects on dentrification in the study area. Therefore, the most appropriate way to the remediation of degraded deserificaltion soil is to allow the natural plante communities to develop in order to improve site conditions in the early stage of the soil remediation and then to select appropriate tree species with the mixed model of coniferous hroadleaved species.%次生林是喀斯特森林生态系统的组成部分,未来的森林可能就是次生林.土壤有机碳(SOC)是土壤有机质的重要组

    BACKGROUND:It is generaly believed that the spine wil be extended, and vertebral muscle atrophy, bone loss of vertebral body, increased height and area of intervertebral disc, changes of composition of intervertebral disc wil occur in the condition of weightlessness. These are likely to be the cause of high incidence of low back pain. OBJECTIVE:To observe changes in lumbar spine bone microstructure analysis of simulated weightlessness on rhesus lumbar spine biomechanics. METHODS:Fourteen young rhesus monkeys were randomly divided into two groups: control group (n=7;free activities in the cage during the experiment), and experimental group (n=7; the use of head-down-10° on a special bed by bundle lying to simulate weightlessness). RESULTS AND CONCLUSION:(1) The results of Micro-CT examination: in the experimental group, structure model index in trabecular bone of increased. Trabecular bone changed from plate-like to the rod-like change. The intersection number of bone tissue in unit length to non-bone tissue declined. The average width of the canal between the trabecular bone increased, suggesting that there have been signs of osteoporosis in the experimental group. (2) Under an optical microscope, in the experimental group, bone hyperplasia line was disordered and irregular. Thick endplate trabecularbone became smal, shalow, and arranged substantialy perpendicular to the direction of trabecular bone and cartilage endplate. The closer the endplate surface, the smaler trabecular bone was. Compared with the control group, these smal trabecular bones were thin and curved. Bone marrow cavity was oval. The degree of the connection between the trabecular bones is poor, reflecting the structural characteristics of significant osteoporosis. (3) It is indicated that weightlessness affected the biomechanical properties of rhesus lumbar motion unit.%背景:一般认为在失重状态下,脊柱会出现异常延长、椎旁肌萎缩、椎体骨量丢失、椎间盘的高

Discusión: Se puede concluir que un poco más de la mitad los casos que se diagnosticaron con IAM en el HSJD, durante el periodo de estudio obedecen a la exposición activa de los pacientes al tabaquismo.Rationale: Cigarrette smoking is the main, preventable cause of premature illness, disability and death worldwide. At present, is widely recognized as a risk factor for the development of cardiovascular disease. Nevertheless, even though tobacco is generaly accepted as a direct cause of acute myocardial infarction, in our country, knowledge about its attributable fraction is limited. Objective: The purpose of this study is to evaluate the impact of cigarrette smoking on acute myocardial infarction patients measuring its attributable fraction. With this study, our purpose is to estimate the proportion of patients who could prevent the development of an acute myocardial infarction if exposure to this risk factor was avoided. Methods: A case-control study was done in the internal medicine and surgery wards at the San Juan de Dios Hospital comprising the period between april the 1st and september the 23rd of 2005. A smoker was defined as any patient which had smoked, at least, 1 cigarrette a day during 1 year. According to their smoking habits, the patients were classified as: non smokers (never smoked, smokers (current smokers and ex-smokers. The magnitude of the associations between the exposure and the risk of illness was measured by means of the 2:1 paired odds ratio in which we defined those not exposed as the non smokers. Those who had not smoked for over 15 years were classified as non smokers (given the long-term benefits which quitting entails and those who had not smoked for less than 15 years were classifed as smokers. To measure the impact of cigarrette smoking on acute myocardial infarction patients, we used the indicator called

    low for both groups. Intake of folate and vitamin D supplements was generaly high in the pregnant group and led to significantly higher total estimated intake of vitamin D and folate in the pregnant group. Iron intake from foods tended to be lower in pregnant women al-though iron supplement intake evened out the difference with respect to iron intake from foods only. Energy intake was slightly lower in pregnant women but not significant, a reflection of that they reported consuming significantly less of rice, meat/fish, and vegetables (grams/day) than the women in the referent group.ConclusionIn the present study, women in early pregnancy reported less intake of vegetables, mice, meat, and alcohol than non-pregnant women. As they also had a low intake (below the Nordic Nutritional Recommendations) of folate, vitamin D, and iron from foods, some of these women and their unborn children are possibly at risk for adverse effects on the pregnancy and birth outcome.

    Regulation of Ca2+ homeostasis plays a critical role in oligodendrocyte function and survival. Canna-binoid CB2 and CB2 receptors have been shown to regulate Ca2+ levels and/or K+ currents in a variety of cell types. In this study we investigated the effect of cannabinoid compounds on the Ca2+ influx elicited in cultured oligodendro-cytes by transient membrane depolarization with an elevated extracellular K+ concentration (50 mM). The CB2 re-ceptor agonist arachidonoyl-chloro-ethanolamide (ACEA) elicited a concentration-dependent inhibition of depolariza-tion-evoked Ca2+ transients in oligodendroglial somata with a maximal effect (94 ± 3)% and an EC50 of 1.3 ±0.03 μM. This activity was mimicked by the CB2/CB2 agonist CP55,940, as well as by the endocannabinoids N-arachidonoyl-ethanolamine (anandamide, AEA) and 2-arachidonoylglycerol (2-AG), whereas the CB2 receptor se-lective agonist JWH133 was ineffective. The CB2 receptor antagonist AM251 (1 μM) also reduced the Ca2+ response evoked by high extracellular K+ and did not prevent the inhibition elicited by ACEA (3 μM). Nevertheless, the a-bility of ACEA and AEA to reduce depolarization-evoked Ca2+ transients was significantly reduced in oligodendro-cytes from CB2 receptor knockout mice, as well as by pretreatment with pertussis toxin. Bath application of the in-wardly rectifying K+ channels (Kir channels) blockers BaCl2 (300 μM) and CsCl2 (1 mM) reduced the size of volt-age-induced Ca2+ influx and partially prevented the inhibitory effect of ACEA. Our results indicate that eannabinoids inhibit depolarization-evoked Ca2+ transients in oligodendrocytes via CB2 receptor-independent and -dependent mech-anisms that involve the activation of PTX-sensitive Gi/o proteins and the blockade of Kir channels.

    Full Text Available Il presente articolo si propone di indagare la versione pascaliana dell’agostinismo, sovente intesa dalla faziosa ermeneutica come anacronistico arroccamento nel medievalismo religioso, che, invece, proprio in virtù nella sua natura inattuale, e della matrice così straordinariamente inesauribile del pensiero agostiniano, si rivela profondamente moderna. Pascal, infatti, addolorato dalla vista di un esistente dibattentesi come una canna tra i venti delle configgenti istanze culturali e religiose del suo tempo, tra le rinnovate forme di eresia e l’imperante libertinismo, non vede in Agostino l’immagine aurea e pacifica di un Santo lontanissimo, non trova in lui il rifugio in un passato rassicurante, bensì di quegli recupera gli elementi drammatici, l’attenzione alla sofferta inquietudine dell’uomo dilaniato dalle dicotomiche alternative, disperatamente disperdentesi nelle malìe dell’esistere, cui entrambi i pensatori indicano il ritorno all’interioritas, a quel cuore non senza (Rragione. Tale ricerca ha messo in luce la riduttività dell’accostamento di Pascal ad Agostino solo per la via del religioso, perché, in fondo, è la problematicità e la problematizzazione del religioso che da Agostino giunge a Pascal e, confrontandosi con la crisi dei valori del 600, perverrà ad avere effetti disattesi.  This article aims to investigate Pascal version of augustinism, often considered from the partisan hermeneutic as anachronistic entrenchment in religious medievalism, which, precisely because of its outdated nature, and so extraordinarily inexhaustible kind of Augustine's thought is revealed to be profoundly modern.

    the germination. The affinity of contact between the layer of dragée and surface of the seeds is favorable to the formation of a water coat. That coat does not permit the oxygenation of the seeds unable the beginning of the germination. Because of that during the first day after the planting the formation of the water coat layer must be avoided the application of irrigation. Best results with fungicides with agents such metalaxyl, iprodyon, benomyl, mancoceb with the concentration 3-3 and mineral nutrients such N, P2O5, K2O, MgO, Fe, Zn, Mn, B, Cu, Mo, Co with the concentration 0.2, 0.1, 0.15, 0.06, 0.00045, 0.00025, 0.0011, 0.00057, 0.00045, 0.000084 0.00001 g/kg dolomite powder were obtained, respectively. With this fungicides and mineral nutrients concentrations were obtaining very good germinations (higher than 90%) without surging phytotoxication and other abnormalities. In case of this dragée utilization can make possible the intensive use of highest quality seeds wich because of their higher costs are prohibitive in the actual system of production by mechanical seeding, generaly. For example actually 2 to 3 kgs of tomato seeds are use per hectare for planting. However 0.2 to 0.3 kgs of seeds should be sufficient to produce the seedlings to the same area.
