    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.

    Complete genome sequences were obtained from nine isolates of canna yellow streak virus (CaYSV). CaYSV belongs to the sugarcane mosaic virus (SCMV) subgroup of potyviruses with johnsongrass mosaic virus (JGMV) as its closest relative. Multiple sequence alignments showed a pattern of amino acid substitutions in the CP sequences, which enabled us to relate these isolates to South East Asian or European isolates. Biological characterization of CaYSV identified Nicotiana benthamiana, Chenopodium quinoa and Phaseolus vulgaris as experimental hosts. Given the popularity and global trade of cannas, a clear picture of the genetic diversity of CaYSV is critical to disease management. PMID:25567205

    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.

    In a kinetic experiment, the absorption of NH4+, NO3- and H2PO4- by three different emergent macrophytes (Canna generalis, Cyperus papyrus, Colocasia tonoimo) in waterlogged condition were analyzed in relation to values of landscape esthetics and economic value. Based on the analysis, the uptake rate of H2PO4- was highest in C. generalis. In fact, C. generalis continued to absorb H2PO4- in even low ion concentration conditions. This suggested that C. generalis successfully coped with a wide range of H2PO4- concentration. On the other hand, the uptake rate of NO3- was highest in C. papyrus. It was, however, not able to successfully adapt to low nutrient conditions (as C. generalis). The highest uptake rate of NH4+ was also in C. papyrus, and even of low concentrations of NH4+. Also, NH4+ absorption was lowest in C. generalis. The application scope of three plants on restoration of polluted water varied with ion absorption characteristics of the plants. C. generalis did generally well in all levels of H2PO4- polluting water. C. papyrus, on the other hand, was only suitable for pre-treatment of seriously NO3- polluting water. Then C. generali was usable in maintaining water quality after improvement to a certain degree. C. papyrus was applicable in various concentrations ofNH4+ polluting water. C. generalis grew better in water environments that were less polluted by NH4+.%本文用动力学试验研究了具有景观价值的3种挺水植物-水生美人蕉(Cannageneralis)、细叶莎草(Cyperuspapyrus)、紫芋(Colocasiatonoimo)对H2PO4-、NH4+、NO3-的吸收特征及差异.试验结果表明:3种挺水植物吸收H2PO4-时,美人蕉的吸收速率最快,且在较低离子浓度条件下也可以吸收该离子,说明其具有嗜磷特性,能够适应广范围浓度H2PO4-环境;吸收NO3-时,细叶莎草的速率最快,但对低浓度NO3-环境的适应能力较差,美人蕉吸收NO3-的特性与细叶莎草刚好相反;吸收NH4+时,细叶莎草的吸收

    Full Text Available In any organization, the demand for both specialists and generalists is unquestionable. Specialists are those who give technical details to generalists considered better decision-makers; the latter ones will know how to process specific information as they posses in knowledge various areas . In this article we present the preference of some countries for generalists or, by case, for specialist. Reforms, initiated during the last 2-3 decades, demonstrate that countries all over the world acknowledge the necessity of both categories. Still, our country needs to overcome its communist tradition, and following the overwhelming demand for generalist we assimilate this category to that of public managers and especially to that of specialist in Public Administration.

  11. Enhanced bioremediation of BTEX contaminated groundwater in pot-scale wetlands.

    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.

    Viscosity reduction has a great impact on the efficiency of ethanol production when using roots and tubers as feedstock. Plant cell wall-degrading enzymes (PCWDEs) 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 (CoMPP), 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. (Canna...... edulis) 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 Canna edulis Ker. cell wall caused difficulty in viscosity reduction...

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

    Science.gov (United States)

    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).

    Wetland aquatic plants including Canna glauca L., Colocasia esculenta L. Schott, Cyperus papyrus L. and Typha angustifolia L. were used in the phytoremediation of submerged soil polluted by arsenic (As). Cyperus papyrus L. was noticed as the largest biomass producer which has arsenic accumulation capacity of 130-172 mg As/kg plant. In terms of arsenic removal rate, however, Colocasia esculenta L. was recognized as the largest and fastest arsenic remover in this study. Its arsenic removal rate was 68 mg As/m2/day while those rates of Canna glauca L., Cyperus papyrus L. and Typha angustifolia L. were 61 mg As/m2/day, 56 mg As/m2/day, and 56 mg As/m2/day, respectively. Although the 4 aquatic plants were inferior in arsenic accumulation, their high arsenic removal rates were observed. Phytostabilization should be probable for the application of these plants.

    The formaldehyde absorption capacity of four plant species, i. e. ,Taxus chinensis, Canna indica, Fatsia japonica and Jasminum sambac was studied with a sealed chamber of boilerplate by three formaldehyde concentrations. The results showed that all the four plant species had a pretty good absorption capacity to formaldehyde. By comparing the absorption rate of formaldehyde with 3 different concentrations in 12 hours, Taxus chinensis was the best, followed by Canna indica and Fatsia japonica, the formaldehyde absorption rate of Jasminum sambac was the weakest. The formaldehyde absorption amount per unit leaf area was increased along with the concentration increment. Under high formaldehyde concentration, the absorption amount per unit leaf area of Canna indica was the highest, indicating the formaldehyde absorption capacity of Canna indica was the strongest among the four plant species.%以红豆杉、美人蕉、八角金盘、茉莉等4种植物为研究对象,通过人工模拟环境,在3种不同甲醛浓度下探讨4种植物吸收甲醛的能力.结果表明:4种植物对甲醛均有较好的吸收能力;综合考虑12 h内3种浓度下整个植株的吸收率,红豆杉的吸收效果最好,美人蕉和八角金盘次之,茉莉的吸收效果最差;4种植物单位叶面积吸收量随甲醛浓度的增大而增大,高浓度下美人蕉的单位叶面积吸收量最大,其吸收能力最强.

    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 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.

    The objective of present study was to assess the simultaneous removal of organics and nitrogen by four lab-scale vertical subsurface flow constructed wetlands (V-SFCWs). The emergent plants employed were Canna indica. Five-month experiments showed that the planted and aerated system largely reduced the COD by 95%, NH4 by 88% and total inorganic nitrogen (TIN) by 83%. It outperformed the unplanted or simple aerated system and was much better than non-aerated system. The study provided a strong evidence to support widespread research and application of spray aeration as a low-cost and energy-efficient aeration technology in V-SFCWs.

    Starches from five underutilized tubers (canna, potato, Chinese yam, water chestnut, and taro) were extracted to investigate quantitative structure-property relationships (QSPR) in each starch using a combination of X-ray diffraction (XRD) and small-angle X-ray scattering (SAXS). Structural parameters of the tuber starches were determined using the paracrystalline model. Swelling power (SP), water solubility index (WSI), amylose leaching (AML), and thermal properties were also measured. The XRD results indicated that starches from Chinese yam, water chestnut, and taro are C-type starches with relatively high crystallinity (29.23-35.02%). In contrast, canna and potato starches are B-type starches exhibiting lower crystallinity and higher amylose content. The paracrystalline model provided a better fit for the C-type starches than for the B-type starches because the former was highly compressible (indicated by a higher "β" value). B-type starches, on the other hand, tend to be more rigid along the lamellar repeat direction, requiring the layers to bend to accommodate internal stress. The QSPR analysis showed that three structural parameters, "Ø", "β", and "Δρu", correlate well with the SP and WSI, and thus can be used to predict certain physicochemical properties. PMID:26041241

    The aim of this study was to evaluate the performance of two pilot horizontal flow constructed wetlands (HFCWs) with and without vegetation. Three types of plants namely Canna, Phragmites australis and Cyprus papyrus were used. The surface area of each plant was 654 m(2). The flow rate was 20 m(3) d(-1) and the organic loading rate range was 1.7-3.4 kg BOD d(-1) with a detention time of 11 days. The results obtained showed that planted HFCW produced high quality effluent in terms of reduction of chemical oxygen demand (COD; 88%), biochemical oxygen demand (BOD; 91%) and total suspended solids (TSS; 92%) as well as nutrient removal. In addition, 4 logs of total coliform were removed from the planted unit compared with only 3 logs in the unplanted one. The phosphate uptake by the plants reached 29, 30.91 and 38.9 g P m(-2) for Canna, Phragmites and Cyprus, respectively, with 60% removal rate in the treated effluent. The nitrogen uptake by the same plants reached 63.1, 49.46 and 82.33 g N m(-2). Although, the unplanted unit proved to be efficient in the removal of COD, BOD and TSS, it lacks efficiency in pathogen and nutrient removal. The reclaimed wastewater, after disinfection, could be reused for non-restricted irrigation purposes. PMID:24434966

    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.

    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

  19. Radiological physics of heavy charged-particle beams used for therapy

    International Nuclear Information System (INIS)

    The beams available for biological investigations at the Bevatron or at the Bevalac range from helium to iron ions. However, only carbon, neon, and argon beams have been used for therapy. The treatment techniques are arbitrarily divided into two categories: small field and large field irradiation. Examples of the small field treatments are pituitary irradiation, which generaly utilizes the plateau portion of the helium depth-dose curve, and treatment of ocular melanoma, which uses a modified Bragg peak of the helium beam. Large field treatments for cancer therapy generally requires a beam that has a large uniform transverse profile and a modified Bragg peak. Procedures and instrumentation for patient irradiations at the Bevatron/Bevalac have been based on the prior experience obtained at the 184-inch Synchrocyclotron, and for that reason both facilities are discussed

    2002-09-01

    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. Ha destato, perciò, in me meraviglia leggere l’articolo scritto contemporaneamente da Beniamino Moro (2001 e pubblicato nel numero 215 di questa rivista, che raggiunge lo stesso risultato con argomentazioni di segno opposto.

    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.

  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...

    Carlo Rossetti

    2011-02-01

    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.

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...

  20. 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.

    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.

    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)

    The growth of composite plants(canna and iris) in pure vegetal floating island and floating islands filled with straw filler and spherical plastic filler,and the remediation effects of nitrogen pollutants,total phosphorus and CODMn have been studied comparatively. The results show that canna and iris in floating island with straw matrix grow faster,and the next is the floating island with spherical plastic filler. Both are superior to pure vegetal floating island. The reason why negative growth occurs to CODMn in straw matrix floating island system is caused by the excess water-soluble substances released from histocyte of straw.%对比研究了稻草填料、塑料球形填料作为浮岛基质时及纯植物浮岛中复合植物(美人蕉和菖蒲)的生长情况,氮素污染物、总磷和CODMn指数的修复效果。实验结果表明:稻草基质浮岛中的美人蕉和菖蒲株高增长最快,其次是塑料球形填料浮岛,均优于纯植物浮岛。其中稻草基质浮岛系统中CODMn出现负增长的原因是稻草组织细胞中过量的水溶性物质释放所导致。

The results reveal that red leave beet ( Beta vulgaris var cicla) has the highest total nitrogen removal rate amounting to 85.72% , while water spinach ( Ipomoea aquatica) keeps the highest total phosphorus removal rate of 95.6% , and water spinach (Ipomoea aquatica) and Canna (Canna indica) both are able to remove nearly all the ammonia nitrogen in the water. Moreover, the water body and the season should be considered when selecting plants on the floating bed, and a 30% floating bed coverage could help a-chieve the best effect. The results could provide theoretical basis for applying biological floating island to water ecological restoration.

    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.

    In order to investigate the correlation of nitrogen and phosphorus accumulation with rhizospheric microbes, as well as the assimilative potentials of several wetland plant species, such relationships of Phragmites communis, Zizania caduciflora Hand Mazz, Cyperus papyrus Linn, Scirpus validus Vahl, Canna indica and Iris germanica Linn were studied in combination with the research on wetland restoration and its demonstration technologies for Miju River estuary situated at the northern Erhai Lake. The correlation between nitrogen accumulation of Phragmites communis and Canna indica and biomass of their rhizospheric nitrogen-fixing bacteria was found evidently positive, whilst that of the others was unmarked. Furthermore, simple regression and partial correlation analyses were also conducted to focus on the influence of environmental factors of the wetland system such as total nitrogen in surface soil, total nitrogen and dissolved oxygen in water body. In general, all of the factors would make rather great impacts on the biomass of rhizospheric nitrogen-fixing bacteria. However, the correlation of nitrogen accumulation of Phragmites communis and Canna with their rhizospheric nitrogen-fixing bacteria was slightly affected by those environmental factors, and it was further confirmed that there were co-metabolic activities between their nitrogen accumulation and rhizospheric nitrogen-fixing bacteria.%为研究湿地植物的氮、磷累积量与其根际微生物之间的相关性,并调查湿地植物的净化潜能,结合位于洱海北部的弥苴河河口湿地恢复和示范技术,对芦苇、茭草、纸莎草.水葱、美人蕉和鸢尾6种湿地植物进行了相关性研究分析。结果表明,芦苇,美人蕉氮素累积量与其根际固氮菌总数呈显著正相关关系,而其他4种湿地植物的相关性不显著。针对湿地系统的环境因素,如表层土壤全氮、湿地水体总氮和溶解氧的影响,也作了简单的回归

    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.

    Climatic Changes, and more generaly Global Changes, play a major role in environmental modifications related to public health. Modifications of temperatures, precipitations... influence ecological habitats. These habitats can be adapted for some animals species, responsable for predestinate pandemics. Mosquitoes and birds represent for certain pandemics the essential elements of virus transmission. Abundance of mosquitoes and birds species, is heavily conditioned to favorable ecological habitats, flooded areas extent and their variations. The study we carried, has been done in South of France. We show present status of ecological habitats and flooded durations in relation with actual climat. We have refine mediterranean spatial knowledge in mediterranean basin with actual data. We show evolution of climat and consequences for bioclimatic stages, using world clim data and IPCC scenarii. We reach environment impact for certain virus like West Nile virus. This virus affects birds, horses and hands up to men (e.g.West Nile virus appeared in 1999 in USA, between 1999 and 2007 : 27 000 human cases including 1 050 deaths). Presence of the virus is conditioned by different factors, primarily including vector distribution (mosquitoes). We show how it’s possible to localise favorable areas for the virus and to predict its future expansion areas. We present maps of the possibilities for future concerning previsions of bioclimatic steps variations. Thanks to the latest remote sensing and spatial analysis techniques. Our maps may be used as precious tools to help decision makers when faced with mosquito related problems.

    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.

    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.

    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.

    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.

    Full Text Available Industrial play a major role in country's economy. Air pollution is an occupational health problem in industries. Generaly, there are more man made pollution in the air of heavy industries and major cities around the industries, Exposure as inhalation represents one of the major routes by which the body can be exposed by accident or design to foreign materials. One having entered to the respiratory tract, inhaled materails may be readly absorbed or may react directly with the alveolar epithelium and entered in to the blood steam. These air pollution induce many changes in physiological and biochemical process. The present study was contucted on chromate industrial workers as these workers were repeatedly exposed to pollutants in chromium factors (Tamil Nadu Chromate and Chemical Ltd., Ranipet industrial Town, Tamil Nadu. The bioaccumulation of chromium was estimated from one hundred samples of blood and urine as well as twenty five samples of nails collected from TCC industrial workers and control subject. The workers and control subject were randomly selected. Estimation was carried out by Atomic Absorption spectrometry. From the results it was obeserved tha the accumulation of heavy metal chromium in the blood. urine and nail samples of chromate factory worker are above the normal ranges. Results are statistically significant.

    A parasitological survey was carried out on 222 inhabitants of five farms in Holambra, located 30 km north of Campinas, São Paulo, Brazil, on October 1992. Approximately 70% of the inhabitants were found to be infected with at least one species of intestinal parasite. The positive rates of 6 helminths and 7 protozoan species detected are as follows: 5.4% Ascaris lumbricoides; 8.6% Trichuris trichiura; 19.8% Necator americanus; 10.4% Strongyloides stercoralis; 1.4% Enterobius vermicularis; 0.9% Hymenolepis nana; 3.2% Entamoeba histolytica; 2.7% E. hartmanni; 9.9% E. coli; 14.0% Endolimax nana; 2.3% Iodamoeba butschlii; 10.4% Giardia lamblia; 37.8% Blastocystis hominis. The positive rates of helminth infection were generaly higher in the younger-group under 16 years-old than those in the elder group aged 16 or more, whereas the infection rates of protozoan species were higher in the elder group. The infection rate of Strongyloides was found to be 10.4% by a newly developed sensitive method (an agarplate culture methods). PMID:7569635

    2013-01-01

    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.

    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.

  10. The proactive historian: Methodological opportunities presented by the new archives documenting genomics.

    Science.gov (United States)

    García-Sancho, Miguel

    2016-02-01

    In this paper, I propose a strategy for navigating newly available archives in the study of late-twentieth century genomics. I demonstrate that the alleged 'explosion of data' characteristic of genomics-and of contemporary science in general-is not a new problem and that historians of earlier periods have dealt with information overload by relying on the 'perspective of time': the filtering effect the passage of time naturally exerts on both sources and memories. I argue that this reliance on the selective capacity of time results in inheriting archives curated by others and, consequently, poses the risk of reifying ahistorical scientific discourses. Through a preliminary examination of archives documenting early attempts at mapping and sequencing the human genome, I propose an alternative approach, in which historians proactively problematize and improve available sources. This approach provides historians with a voice in the socio-political management of scientific heritage and advances methodological innovations in the use of oral histories. It also provides a narrative framework in which to address big science initiatives by following second order administrators, rather than individual scientists. The new genomic archives thus represent an opportunity for historians to take an active role in current debates concerning 'big data' and critically embed the humanities in pressing global problems.

    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.

    DNA methylation, an important epigenetic modiifcation, serves as a key function in the polyploidization of numerous crops. In this study, early generations of resynthesizedBrassica napus (F1, S1–S3), ancestral parentsB. rapaandB. oleracea were analyzed to characterize their DNA methylation status during polyploidization, applying DNA methylation-sensitive ampliifca-tion polymorphism (MSAP) and high-performance liquid chromatography methods. InF1, 53.4% fragments were inherited from both A- and C-genomes. Besides, 5.04 and 8.87% fragments inF1 were inherited from A- and C- genome, respectively. 5.85 and 0.8% fragments were newly appeared and disappeared in resynthesizedB. napus, respectively. 13.1% of these gene sites were identiifed with methylation changes inF1, namely, hypermethylation (7.86%) and hypomethylation (5.24%). The lowest methylation status was detected inF1 (38.7%) compared with in S1–S3. In S3, 40.32% genes were methylated according to MSAP analysis. Sequencing of methylated fragments indicated that genes involved in multiple biological processes were modiifed, including transcription factors, protein modiifcation, and transporters. Expression ananlysis of DNA methyltransferase 1 andDNA methyltransferase chromomethylase 3 in different materials was consistent to the DNA methylation status. These results can generaly facilitate dissection of how DNA methylation contributes to genetic stability and improvement ofB. napus during polyploidization.

    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.

  16. In vitro studies on non-protein nitrogen utilization by rumen microflora. I. Effect of nature of energy and minerals using phosphorus-32 as a label of microbial growth

    International Nuclear Information System (INIS)

    The effect of the nature of carbohydrates and minerals on microbial growth has been studied in vitro to intensify rumen microbial protein synthesis from non-protein nitrogen. The two methods used are a classical one based on decrease of ammonia in the incubation medium and one measuring 32P incorporation in microflora. The nature of starch greatly influences urea utilization. Maize starches with high amylose content (50-60%) and B-type X-ray diffraction pattern allow a lower rate of urea utilization than starch from normal or waxy maize. Large starch granules, such as those found in some varieties of tropical tubers, also reduce urea utilization. Among the tropical tubers studied yam Cayenensis and canna Edulis give lower urea utilization than cassava and yam Dumetorum. However, this can be improved by processing; extrusion of maize and pelleting of tropical tubers promotes urea utilization. The effect is greatest when the proportion of urea to processed cereal is about 4-5%. Protein synthesis is not further improved when the percentage of urea exceeds 12%. Adding phosphorus and zinc to the incubation medium does not affect urea utilization. However, the addition of sulphur in the form of sulphate improves urea utilization with both natural and purified diets. (author)

  17. MEDICINAL CANNABIS LAW REFORM IN AUSTRALIA.

    2016-03-01

    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.

    Microcosm horizontal subsurface flow constructed wetlands (HSSFCWs) were used to examine the impacts of vegetation on nitrogen dynamics treating different influent COD/N ratios (1:1, 4:1, and 8:1). An increase in the COD/N ratio led to increased reductions in NO3 and total inorganic nitrogen (TIN) in planted and unplanted wetlands, but diminished removal of NH4. The HSSFCW planted with Canna indica L. exhibited a significant reduction in NH4 compared to the unplanted system, particularly in the active root zone where NH4 removal performance increased by up to 26 % at the COD/N ratio of 8:1. There was no significant difference in NO3 removal between the planted and unplanted wetlands. TIN removal efficiency in the planted wetland increased with COD/N ratios, which was likely influenced by plant uptake. NH4 reductions were greater in planted wetland at the 20- and 40-cm depths while NO3 reductions were uniformly greater with depth in all cases, but no statistical difference was impacted by depth on TIN removal. These findings show that planting a HSSFCW can provide some benefit in reducing nitrogen loads in effluents, but only when a sufficient carbon source is present. PMID:26822218

    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. PMID:26708488

    Full Text Available This work assesses the performance of a municipal pilot wastewater treatment system employing an up-flow anaerobic filter (UAF followed by a horizontal subsurface constructed wetland (HSSCW. This pilot scale demonstration project was implemented in a zone with subtropical climate in order to protect Lake Chapala from wastewater loads that are discharged by small communities in the Lake’s vicinity. The filters were filled with tezontle as the media for biofilm support and the HSSCW was planted with two ornamental plants species, Canna hybrids and Strelitzia reginae. The experiment evaluated three hydraulic retention times (HRT of 18, 28 and 38 h in the UAF, which corresponds to two, three and four days in HSSCW over 66 weeks. The mean efficiencies found for the complete system were 80% and 90% of BOD, 80% and 86% of COD, 30% and 33% of Ntot and between 24% and 44% of Ptot. It was possible to remove almost 80% of organic matter in 18 h in the UAF while the HSSCW reached 30% of removal for Ntot in a HRT of three days. As expected, the UAF was responsible for removing most of the organic matter and the HSSCW removed most of the nitrogen.

    The aim of this study was to evaluate the domestic wastewater treatment efficiency as well as the survivability of commercially valuable ornamental plants in subsurface flow wetlands (SSFW) for domestic wastewater (DWW) treatment in laboratory and pilot wetland studies. The laboratory scale study included five different species (Zantedeschia aethiopica, Strelitzia reginae, Anthurium andreanum, Canna hybrids and Hemmerocallis dumortieri) that were evaluated in horizontal flow subsurface treatment cells. All the plants survived during the 6-month experimental period demonstrating high wetland nutrient treatment efficiency. In order to validate and expand these preliminary results, a pilot-scale wetland study was carried out in SSFWs under two different flow regimes (horizontal and vertical flow). Four ornamental species were tested during a 1-year period: Zantedeschia aethiopica, Strelitzia reginae, Anthurium andreanum and Agapanthus africanus. The removal efficiencies were significantly higher in the vertical subsurface-flow constructed wetlands (VFCW) for all pollutants, except for nitrate (NO(3)-N), total nitrogen (TN) and total suspended solids (TSS). These results show that it is feasible to use select non-wetland plants with high market value in SSFWs without reducing the efficiency of the wastewater treatment system, although future work should continue in order to apply this technology in a large scale. The added value of floriculture in treatment wetlands can help to promote the use of constructed wetlands (CW) for domestic wastewater treatment in developing countries where economical resources are scarce and water pollution with DWW is common.

    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 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. PMID:26248021

    In this study, nitrogen removal was investigated in pilot-scale subsurface flow (SSF) and in free water surface flow (FWS) constructed wetlands installed in the campus of TUBITAK-Marmara Research Center, Gebze, near Istanbul, Turkey. The main purposes of this study are to apply constructed wetlands for the protection of water reservoirs and to reuse wastewater. Experiments were carried out at continuous flow reactors. The effects of the type of plants on the removal were investigated by using emergent (Canna, Cyperus, Typhia spp., Phragmites spp., Juncus, Poaceae, Paspalum and Iris.), submerged (Elodea, Egeria) and floating (Pistia, Salvina and Lemna) marsh plants at different conditions. During the study period HLRs were 30, 50, 70, 80 and 120 L m(2)d(-1) respectively. The average annual NH4-N, NO(3)-N, organic N and TN treatment efficiencies in SSF and FWS wetlands are 81% and 68%, 37% and 49%, 75% and 68%, 47% and 53%, respectively. Nitrification, denitrification and ammonification rate constant (k20) values in SSF and FNS systems have been found as 0.898 d(-1) and 0.541 d(-1), 0.488 d(-1) and 0.502 d(-1), 0.986 d(-1) and 0.908 respectively. Two types of the models (first-order plug flow and multiple regression) were tried to estimate the system performances. PMID:16114631

    Full Text Available Schistosomiasis is considered as one of the most important trematode disease of man. The most important goal of the present study is to use the natural plants as cheaper and available sources for snail control. The present investigation concerned with the evaluation of toxicological, biological and physiological effects of water suspension, cold water and boiled water extracts of Agave filifera whole plant, Ammi majus flowers and leaves and Canna indica flowers and leaves comparing with the effect of different sulphate compounds. The present work revealed that, copper sulphate as well as the water suspension of Ammi majus flowers and leaves disclosed the most potent effect on the cumulative mortality after 6 weeks exposure periods. Also, egg laying capacity and egg hatchability of Biomphalaria alexandrina snails were affected with the exposure to CuSO4 and water suspension of Ammi majus flowers. The sublethal doses (LC10 of copper sulphate and water suspension of the tested plants reduced the total protein and total lipid contents of the hemolymph of B. alexandrina snails. The activity of transaminases enzymes as well as acetylcholinesterase had been affected by the exposure to the sublethal doses of copper sulphate and the water suspension of the tested plants. Also, histopathological changes were recorded in hermaphrodite gland of B. alexandrina snails post 6 weeks of exposure.

  11. Effects of the source of energy and minerals on microbial protein synthesis in rumen using 35S as indicator. Part of a coordinated programme on tracer techniques in studies on the use of non-protein nitrogen in ruminants

    International Nuclear Information System (INIS)

    Part I. The effect of the nature of carbohydrates and minerals on microbial growth in vitro was studied in vitro to intensify rumen microbial protein synthesis from non-protein nitrogen, using phosphorus incorporation (PR). The nature of starch greatly influences urea utilization. Among the tropical tubers studied, yam Cayenesis and canna Edulis give lower urea utilization than cassava and yam Dumetorum. However, this can be improved by processing. The effects are greatest when the proportion of urea to processed cereal is ca. 4-5%. S-addition as sulfate improves urea utilization with both natural and purified diets. Part II. Results from the Jouy and Ghent laboratories were analyzed statistically, to check the accuracy of the 32P method for estimating microbial growth, using protein-free substrates. The linear relationship between PR and every other variable was studied. Two multivariate analyses, principal components and multiple regression, were applied. Net NH3 utilization was predicted using the equations for substrates with proteins likely to be degraded. This method appears more accurate than using the N/P ratio in microflora. Equations should only be used under the specific experiments described

    Both bacteria and archaeal communities can play important roles in biogeochemical processes in constructed wetland (CW) system. However, the influence of plant type on microbial community in surface water CW remains unclear. The present study investigated bacterial and archaeal communities in five surface water CW systems with different plant species. The abundance, richness, and diversity of both bacterial and archaeal communities considerably differed in these five CW systems. Compared with the other three CW systems, the CW systems planted with Vetiveria zizanioides or Juncus effusus L. showed much higher bacterial abundance but lower archaeal abundance. Bacteria outnumbered archaea in each CW system. Moreover, the CW systems planted with V. zizanioides or J. effusus L. had relatively lower archaeal but higher bacterial richness and diversity. In each CW system, bacterial community displayed much higher richness and diversity than archaeal community. In addition, a remarkable difference of both bacterial and archaeal community structures was observed in the five studied CW systems. Proteobacteria was the most abundant bacterial group (accounting for 33-60 %). Thaumarchaeota organisms (57 %) predominated in archaeal communities in CW systems planted with V. zizanioides or J. effusus L., while Woesearchaeota (23 or 24 %) and Euryarchaeota (23 or 15 %) were the major archaeal groups in CW systems planted with Cyperus papyrus or Canna indica L. Archaeal community in CW planted with Typha orientalis Presl was mainly composed of unclassified archaea. Therefore, plant type exerted a considerable influence on microbial community in surface water CW system. PMID:27392623

    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. PMID:24081640

    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.

    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).

    With the aim of protecting drinking water sources in rural regions, pilot-scale subsurface water flow (SSF) and free water surface flow (FWS) constructed wetland systems were evaluated for removal efficiencies of nitrogenous pollutants in tertiary stage treated wastewaters (effluent from the Pasaköy biological nutrient removal plant). Five different hydraulic application rates and emergent (Canna, Cyperus, Typhia sp., Phragmites sp., Juncus, Poaceae, Paspalum and Iris) and floating (Pistia, Salvina and Lemna) plant species were assayed. The average annual NH4-N, NO3-N and organic-N treatment efficiencies were 81, 40 and 74% in SSFs and 76, 59 and 75% in FWSs, respectively. Two types of the models (first-order plug flow and multiple regression) were tried to estimate the system performances. Nitrification, denitrification and ammonification rate constants (k20) values in SSF and FWS systems were 0.898 d-1 and 0.541 d(-1), 0.486 d(-1) and 0.502 d(-1), 0.986 d(-1) and 0.908, respectively. Results show that the first-order plug flow model clearly estimates slightly higher or lower values than observed when compared with the other model. PMID:16889247

    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.

    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. PMID:26897412

    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. PMID:25757626

    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.

    We identified a previously unidentified conotoxin gene from Conus generalis whose precursor signal sequence has high similarity to the O1-gene conotoxin superfamily. The predicted mature peptide, αO-conotoxin GeXIVA (GeXIVA), has four Cys residues, and its three disulfide isomers were synthesized. Previously pharmacologically characterized O1-superfamily peptides, exemplified by the US Food and Drug Administration-approved pain medication, ziconotide, contain six Cys residues and are calcium, sodium, or potassium channel antagonists. However, GeXIVA did not inhibit calcium channels but antagonized nicotinic AChRs (nAChRs), most potently on the α9α10 nAChR subtype (IC50 = 4.6 nM). Toxin blockade was voltage-dependent, and kinetic analysis of toxin dissociation indicated that the binding site of GeXIVA does not overlap with the binding site of the competitive antagonist α-conotoxin RgIA. Surprisingly, the most active disulfide isomer of GeXIVA is the bead isomer, comprising, according to NMR analysis, two well-resolved but uncoupled disulfide-restrained loops. The ribbon isomer is almost as potent but has a more rigid structure built around a short 310-helix. In contrast to most α-conotoxins, the globular isomer is the least potent and has a flexible, multiconformational nature. GeXIVA reduced mechanical hyperalgesia in the rat chronic constriction injury model of neuropathic pain but had no effect on motor performance, warranting its further investigation as a possible therapeutic agent.

    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.

    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.

    The Wet Mountain Valley is an intermontane trough filled to a depth of at least 6,700 feet with unconsolidated deposits. Ground water occurs under both artesian and water-table conditions within the basin-fill aquifer and ground-water moverment is toward Grape and Texas Creeks. The depth to the water table is less than 10 feet in an area of about 40 square miles along the central part of the valley and is less than 100 feet in most of the remainder of the valley. Ground water stored in the upper 200 feet of saturated basin-fill sediments is estimated to total 1.5 million acre-feet. Yields greater than 50 gallons per minute generally can be expected from wells in the central part of the basin-fill aquifer, and yields less than 50 gallons per minute are generally reported from wells around the edge of the basin-fill aquifer. Yields of wells in the mountainous areas are generally less than 20 gallons per minute. Most streamflow occurs as a result of snowmelt runoff during June and July. The long-term annual runoff at seven stations ranges from an estimated 0.02 cubic foot per second per square mile to an estimated 1.17 cubic feet per second per square mile, generaly increasing with station altitude. Generalized annyal water budgets for two areas in the Wet Mountain Valley indicate that surface-water outflow is only 7 to 11 percent of the total water supply from precipitation and other sources. The remaining water is lost to the atmosphere by evapotranspiration. The quality of both the surface and ground water is generally within the recommended limits for drinking water set by the U.S. Public Health Service. (Woodard-USGS)

After illustrating the position towards the use of stratigraphy of the main currents of opinion on restoration in Italy, the report tackles the question of authenticity and of the interventions to minimise the deterioration effects involving the stratification traces. In order to ensure the recognizability of the restoration interventions, it is proposed to conceive and carry them out as deliberately developed layers, in order to allow the subsequent reading of the sequence.To this aim tricks and procedures are illustrated. The cases of restoration are presented (the “Chiostro delle Cucine” in St. Paul Convent in Parma, St.Marcellus Church in Feltre and St. Cosma and St.Damiano Convent in Venice, which, by means of elaborated techniques, try to combine the conservation and readability of the traces with more general tasks of the restoration.La relazione affronta diversi aspetti del rapporto tra stratigrafia e restauro architettonico.Dopo aver descritto la posizione nei confronti dell’utilizzo della stratigrafia delle principali correnti di pensiero sul restauro in Italia, vengono trattate la questione dell’autenticità e degli interventi a contrasto degli effetti di degrado che coinvolgono le tracce della stratificazione. Ai fini della riconoscibilità degli interventi di restauro, si propone di concepirli e realizzarli come strati intenzionalmente realizzati per consentire a posteriori la lettura della sequenza, e si indicano accorgimenti e modi operativi.Vengono presentati tre casi di restauro (il Chiostro delle Cucine nel Convento di S. Paolo a Parma, la chiesa di S.Marcello a Feltre, il Convento di S.

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.

    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.

    Full Text Available Mediation process means dispute resolution through negotiation process for obtaining a peace agreement between the parties by using a third party in settling the dispute. Article 130 HIR/154 RBg determines peace efforts may use since the trial began before a judge hands down the dispute. Mediation as part of the Alternative Dispute Resolution is a process outside the court, but Indonesian Supreme Court Rules No. 1/2008 integrates it in the court proceedings and allows the mediation process at the level of legal remedy. So the problem investigated is the court decision re-mediated and the peace agreement mediation results. The method used normative legal research by Legislation Approach and to deepen the research study also use a Legal Concept Analysis Approach which is intended to establish a view and legal arguments in solving the problem at hand. Case that has been decided by the courts is not possible to re-mediated. The mediation process at the level of legal remedy is contrary to the law, especially the provisions of Article 130 HIR / 154 RBg. Indonesian Supreme Court Rules as rules are hierarchically under the law (HIR/RBg not justified material being regulated substance exceeding material are governed by higher laws. So Indonesian Supreme Court Rules No. 1/2008 can not be a legal basis to regulate the integration of mediation into the docket particularly about mediation at the level of legal remedy because the principle of lex superiori derogat legi inferiori and the principle of lex specialis derogat legi generali not met.

    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

    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

    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(-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 (ΦPS II) 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.

    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.

    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.

    Interactions between flowers and their visitors span the spectrum from mutualism to antagonism. The literature is rich in studies focusing on mutualism, but nectar robbery has mostly been investigated using phytocentric approaches focused on only a few plant species. To fill this gap, we studied the interactions between a nectar-robbing hermit hummingbird, Phaethornis ruber, and the array of flowers it visits. First, based on a literature review of the interactions involving P. ruber, we characterized the association of floral larceny to floral phenotype. We then experimentally examined the effects of nectar robbing on nectar standing crop and number of visits of the pollinators to the flowers of Canna paniculata. Finally, we asked whether the incorporation of illegitimate interactions into the analysis affects plant-hummingbird network structure. We identified 97 plant species visited by P. ruber and found that P. ruber engaged in floral larceny in almost 30% of these species. Nectar robbery was especially common in flowers with longer corolla. In terms of the effect on C. paniculata, the depletion of nectar due to robbery by P. ruber was associated with decreased visitation rates of legitimate pollinators. At the community level, the inclusion of the illegitimate visits of P. ruber resulted in modifications of how modules within the network were organized, notably giving rise to a new module consisting of P. ruber and mostly robbed flowers. However, although illegitimate visits constituted approximately 9% of all interactions in the network, changes in nestedness, modularity, and network-level specialization were minor. Our results indicate that although a flower robber may have a strong effect on the pollination of a particular plant species, the inclusion of its illegitimate interactions has limited capacity to change overall network structure.

    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

    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. PMID:22661261

    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

    1996-09-30

    The solubilities of two sodium salts of organic acids that are thought to exist in high-level waste at the Hanford Site were measured in tank supernate simulant solutions during FY1996 This solubility information will be used to determine if these organic salts could exist in solid phases (saltcake or sludges) in the waste where they might react violently with the nitrate or nitrite salts present in the tanks. Solubilities of sodium butyrate and trisodium N-(2-hydroxyethyl)ethylenediaminetriacetate were measured in simulated waste supernate solutions at 25 {degrees}C, 30 {degrees}C, 40 {degrees}C, and 50 {degrees}C. The organic compounds were selected because they are expected to exist in relatively high concentrations in the tanks. Two types of tank supernate simulants were used - a 4.O M sodium nitrate - 0.97 M sodium nitrite solution with sodium hydroxide concentrations ranging from O.00003 M to 2.O M and a 2.O M sodium nitrite solution saturated with crystalline sodium nitrate with sodium hydroxide concentrations ranging from 0.1 M to 2. 0 M. The solubilities of sodium butyrate and trisodium N-(2-hydroxyethyl)ethylene- diaminetriacetate in both types of HLW tank supernate solutions were high over the temperature and sodium hydroxide concentration ranges expected in the tanks. The solubilities of these compounds are similar (in terms of total organic carbon) to sodium glycolate, succinate, caproate, dibutylphosphate, citrate, formate, ethylenediaminetetraacetate, and nitrilotriacetate which were measured previously. High solubilities will prevent solid sodium salts of these organic acids from precipitating from tank supernate solutions. The total organic carbon concentrations (TOC) of actual tank supernates are generaly much lower than the TOC ranges for the simulated supernate solutions saturated (at the solubility limit) with the organic salts. This is true even if all the dissolved carbon in a given tank supernate is due to only one of these eight soluble

    Full Text Available A parasitological survey was carried out on 222 inhabitants of five farms in Holambra, located 30 km north of Campinas, São Paulo, Brazil, on October 1992. Approximately 70% of the inhabitants were found to be infected with at least one species of intestinal parasite. The positive rates of 6 helminths and 7 protozoan species detected are as follows: 5.4% Ascaris lumbricoides; 8.6% Trichuris trichiura; 19.8% Necator americanus; 10.4% Strongyloides stercoralis; 14% Enterobius vermicularis; 0.9% Hymenolepis nana; 3.2% Entamoeba histolytica; 2.7% E. hartmanni; 9.9% E. coli; 14.0% Endolimax nana; 2.3% Iodamoeba butschlii; 10.4% Giardia lamblia; 37.8% Blastocystis hominis. The positive rates of helminth infection were generaly higher in the younger-group under 16 years-old than those in the elder group aged 16 or more, whereas the infection rates of protozoan species were higher in the elder group. The infection rate of Strongyloides was found to be 10.4% by a newly developed sensitive method (an agarplate culture methods.Uma pesquisa coproparasitológica foi realizada em 222 habitantes de cinco fazendas de Holambra, localizada a 30 km ao norte de Campinas, SP, Brasil, em outubro de 1992.

    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.

    广义的文化定义主要有"总和说"与"模糊说"两类。把"总和说"进一步扩展为"超广义说",把"模糊说"修改为"自创生说",将两者结合起来称做"超广义自创生文化说"。科学文化指科学本身以及科学与社会其他文化相互交融所形成的文化群类。数学文化指把自然、社会、思维等各个领域中的数量关系、空间形式、信息符号、能量运转、物质结构的哲理精蕴、艺术神采以其微妙深奥的规律化方式智慧地展现出来。数学的文化奇观的表现形式为深蕴的统一性、内增的复杂性、天成的艺术性和奇难的悬疑性等四个方面。%A broad definition of culture mainly includes the summation theory and the vagueness theory. The summation theory can be expanded into the super-generalization theory and the vagueness theory can be trans- formed into the autopoiesis theory. The two theories combined are called the cultural theory of super-generali- zation and autopoiesis. Scientific culture refers to science itself and the mixtures of science and other cultures. Mathematical culture shows the lawfulness of philosophy and artistry in quantitative relation, spatial form, information symbols, energy motion and physical structure of nature, human society and thought. Cultural wonder of mathematics is characterized by unity, complexity, artistry and suspense.

    The upper mixed-layer of seas and oceans is one of the important water areas, the thermodynamic state of which defines many important physical, chemical or biological processes in the sea- atmosphere environment. The same can be note concerning the Black Sea turbulent mixed layer, which represents the object of our investigation. It is well known that the depth of the mixed layer is generaly determined by measurements of water properties: temperature and sigma-t (density) but here the depth of the mixed layer and its variability are investigated by using of the basin-scale numerical model of the Black Sea dynamics of M. Nodia Institute of Geophysics (BSM-IG, Tbilisi, Georgia). The main object of this study is to investigate the Black Sea upper mixed-layer generation and its evolution in connection with the nonstationarity atmospheric circulation and thermohaline action in the inner-annual time scale. Besides, how the temperature and salinity fields of the Black Sea upper layer are substantially reacted by the vertical diffusion coefficient are the centre of our attention. Therefore, the coefficient of vertical turbulent diffusion for heat and salt are tested as constant equal to 10 cm2s-1 and it was parameterized by modified Oboukhov's formula. The results of the numerical investigations show that: in wintertime for any choosing of this vertical diffusion coefficient the intense wind-driven turbulence promotes mixing aproximetly till 16-26 m in deep layers of the Black Sea. Except for that, cold fluxes through the surface and precipitation-evapuration system play aditionally role on the mixed layer forming as well. During the transitive spring season (in difference from the cold season), when the depth of the mixed layer is aproxometly 2-4 m., the role of vertical turbulent viscosity insignificantly grows. In the warm season (summer), when the mixed layer does not observe in the upper layer of the Black Sea, the role of the vertical diffusion coefficient is more

    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.

    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

    汽车发展史上,一些汽车品牌在车身造型上有着鲜明的传承因素,而另一些品牌则没有。一般说来,高端的或者强调个性的汽车品牌比较重视汽车造型设计的传承因素。汽车造型设计的传承体现在车身整体造型和以进气格栅为代表的家族化造型细节上。汽车造型设计的变异体现在追随时代风格、使用全新家族化造型语言和微调家族化造型语言等三个方面。在车型换代设计的过程中,汽车品牌应该根据自身定位、战略规划和市场环境的变化来把握好传承与变异的关系。%In the history of auto industry, some auto brands have deifnite inheritance of car styling while the other brands have not. 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.

    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

At the same time, totally 20 observation sites were established, and the record for 239 monthsamounted to 12 624 individuals. Chinese white dolphins occur all around Xiamen waters of 700 km2, and they mayswim upstream to the Jiulong River but never swim out of Jinmen Island and Wuyu Isle. Generaly, the dolphina aresighted very close to the shore and most frequently occur in areas included west harbour of Xiamen and the mouth ofTong'an Bay. The frequency when the dolphins jumped out of the water varies with season, which is the highest inApril to May. According to surveys and supplementary surveys, nearly 60 individuals are estimated in Xiamen wa-ters, and only 40 individuals are distinctively recorded through having a photos taken. Now the population has thetendency to decrease, so in - situ and off - situ measures should be both employed to emphasize the conservation ofChinese white dolphins, the first - class protected species in China.

    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

    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.

    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

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.

    (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:The incidence rate of peripheral T cel lymphoma is high in Asia, and peripheral T cel lymphoma is aggressive with generaly poor prognosis. However, there is no standard treatment strategy. OBJECTIVE:To retrospectively analyze the therapeutic effect of autologous hematopoietic stem cel transplantation on peripheral T cel lymphoma as wel as relevant toxic and side effects. METHODS:A retrospective review was conducted in 35 patients with peripheral T cel lymphoma who underwent autologous hematopoietic stem cel transplantation from March 2003 to April 2014, including 22 cases of extranodal NK/T-cel lymphoma (nasal type), 1 case of angioimmunoblastic T-cel lymphoma, 8 cases of peripheral T cel lymphoma (non-specific), 3 cases of ALK-positive anaplastic large cel lymphoma, and 1 case of ALK-negative anaplastic large cel lymphoma. Al of 35 patients were classified pathologicaly according to WHO pathological type in 2001 and 2008, and received the high-dose chemotherapy with vincristine, cytarabine, etoposide, mitoxantrone, semustine, cyclophosphamide, and total body irradiation. RESULTS AND CONCLUSION: After a median folow-up of 54 (9-120) months, the probabilities of overal survival and disease-free survival after transplantation were 80% (n=28) and 71% (n=25), respectively. Eight cases (23%) relapsed after transplantation, seven of which died. It was safe with mild and moderate transplantation related side-effects on opportunistic infections, oral cavity mucosa and bladder responses and so on, and there were no severe, life-threatening late complications. Autologous hematopoietic stem cel transplantation may be an effective and safe treatment for peripheral T cel lymphoma, and there is a better benefit in peripheral T cel lymphoma patients with first complete remission.%背景:外周T细胞淋巴瘤亚洲地区发病率高,具有侵袭性,预后普遍较差,目前尚无标准治疗策略。目的:评价自体造血干细胞移植治疗外周T细胞

It was evident how it could not operate in the best way, without wright descriptions of the general and sectors reference. In terminus of efficiency, efficacy and transparency of services offered and the investment made were inadequate. And so in this way the operation was not good enough to pay attention to a valuation of the cost, beneficial of the investment made, that was growing up. It is today getting important to entrust the planning of the information system, that was to be done every year when we talk about a plan with an average limit. So they can be oriented and checked, the choice of the single Administration. In the following work it has been started from the analysis of the italian situation, which expect the use of a specific methodology produced by the AIPA for the planning of informative system in the public administration. The new experimental part of the thesis aims to the adjustment of this methodology to a reality which is the ENEA, that differs for example from that of a Ministry (for that reality on the contrary the proposal of AIPA is optimal), as the institutional aims and the following modalities of administration change, as the corporation is characterised by a strong decentralisation and above all as it has lacked a cognitive research about the different work processes, introduction to the application of AIPA`s proposal.

    BACKGROUND:Lung adenocarcinoma stem cels are a very important marker for diagnosis of lung adenocarcinoma. OBJECTIVE:To investigate the relationship between human lung adenocarcinoma stem cel phenotypes and patient’s prognosis. METHODS:From February 2010 to January 2013, 48 patients with lung adenocarcinoma admitted in the First Affiliated Hospital of Xinjiang Medical University were enroled. Lung adenocarcinoma cancer stem cel phenotypes were detected with immunofluorescence method, and the relationship of different phenotypes and clinical characteristics with patient’s prognosis was compared. RESULTS AND CONCLUSION: SP-C and CCSP expression was observed in the lung adenocarcinoma tissues of 48 cases, possessing the phenotypic characteristics of bronchioloalveolar stem cels. Of the 48 patients, OCT4 was positive in 34 cases (OCT4+ group) and negative in 14 cases (OCT4- group). There was no difference between the two groups in terms of patient’s age, gender, smoking history and tumor stage (P > 0.05). There were 23 cases (68%) in the OCT4+ group with cancer cel metastasis, which was significantly higher than that in OCT4- group (21%;P > 0.05). In the aspects of patient’s age, gender, smoking history, staging and cancer metastasis and other clinical pathological stratification, the 2-year survival rate in the OCT4- group were generaly higher than that in the OCT4+ group, and there was a significant difference in the survival curves of two groups (P 0.05);OCT4+支气管肺泡干细胞组有23例(68%)患者癌细胞转移,明显高于OCT4-支气管肺泡干细胞组(21%),差异有显著性意义(P <0.05);在腺癌患者年龄、性别、吸烟史、分期以及癌细胞转移等临床病理特征分层中,OCT4-支气管肺泡干细胞组肺腺癌2年生存率普遍高于OCT4+支气管肺泡干细胞组,两组生存曲线差异有显著性意义(P <0.05)。结果表明人肺腺癌干细胞具有肺细支气管肺泡干细胞表型特征,同时

    are an ideal method for repair of dentition defects associated with periodontal disease. In summary, the telescopic crown-retained removable partial dentures have good clinical effects, but how to maintain the long-term stability is the main chalenge. In recent years, a variety of ways have been developed to improve the long-term stability, such as changing the inner crown material, which obtains the most prominent achievements, but these methods need to be further observed in clinical applications. Common complications for telescopic crown-retained removable partial dentures include abutment fracture, inner crown shedding, denture fracture, periodontal problems, and reduced retention force, which generaly cannot influence the application of telescopic crown-retained removable partial dentures through repair.

    Infiltration process,in general,is closely related to surface runoff,soil erosion,loss of soil fertility and non-point source pollution.Two series of soil column experiments were performed to study the characteristics of one-dimensional vertical infiltration into a purple clay soil.One was the simulation under the condition of continuous water supply at different ponding water depths and the other was that under intermittent water application at the same water depths.Results indicated that there was no significant effect of ponding water depth on infiltration rate and cumulative infiltration when ponding water depth is between 1 and 10 cm.Soil bulk density and initial water content had great impacts on the infiltration characteristics under the condition of continuous water supply at some ponding depth,which means that infiltration rate and cumulative infiltration increase with the decreased soil bulk density and initial water content.The curves of infiltration into the purple soil are discontinuous under intermittent water application at some water depth.The process in the first period was the same as that under the condition of continuous water supply,and however,infiltration rate and cumulative infiltration were both less than those under the condition of continuous water supply in the second period.The characteristics of infiltration into the purple soil under intermittent water application show significant relation to the cycle and rate of water supply.%土壤入渗与地表径流、土壤侵蚀、土壤养分流失和面源污染等密切相关。通过对紫色土中的黏壤土进行不同积水深度下连续供水和相同积水深度下间歇供水的土柱模拟实验,对紫色土一维垂向入渗特性进行了研究。结果表明,当积水深度为1~10cm时,积水深度对累积入渗量及入渗率基本上没有影响;积水深度一定时,连续供水下土壤容重和初始含水率对紫色土入渗特性有较大影响,累积入渗量和入

Cannaò (1) (1) Dipartimento di Scienze della Terra, Ambiente e vita, University of Genova, Italy (2) Istituto di Geoscienze e Georisorse-CNR, Pisa, Italy In subduction zones, fluid-mediated chemical exchange between slabs and mantle dictates volatile and incompatible element cycles and influences arc magmatism. Outstanding issues concern the sources of water for arc magmas and its slab-to-mantle wedge transport. Does it occur by slab dehydration beneath arc fronts, or by hydration of fore-arc mantle and subsequent subduction of the hydrated mantle? So far, the deep slab dehydration hypothesis had strong support, but the hydrated mantle wedge idea is advancing supported by studies of fluid-mobile elements in serpentinized wedge peridotites and their subducted high-pressure (HP) equivalents. Serpentinites are volatile and fluid-mobile element reservoirs for subduction: their dehydration causes large fluid and element flux to the mantle.However, direct evidence for their key role in arc magmatism and identification of dehydration environments has been elusive and boron isotopes can trace the process. Until recently, the altered oceanic crust (AOC) was considered the 11B reservoir for arcs, which largely display positive δ11B. However, shallow slab dehydration transfers 11B to the fore-arc mantle and leaves the residual AOC very depleted in 11B below arcs. Here we present high positive δ11B of HP serpentinized peridotites from Erro Tobbio (Ligurian Alps), recording subduction metamorphism from hydration at low-grade to eclogite-facies dehydration. We show a connection among serpentinite dehydration, release of 11B-rich fluids and arc magmatism. The dataset is completed by B isotope data on other HP Alpine serpentinites from Liguria and Lanzo Massif. In general, the δ11B of these rocks is heavy (16 to + 30 permil

    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

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 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

    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

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

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.

    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。

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.

    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.

    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.

    BACKGROUND:The type AO-C1 thoracolumbar acute spine injury is a kind of high-energy instable injury, can cause thoracolumbar fracture-dislocation, and mainly associated with spinal nerve injury. Generaly, al needs to posterior open reduction, decompression, bone graft fusion and multiple-segmental internal fixation of pedicle screw rod system, which causes excessive loss of spinal movement segment and a large number of application of internal fixators. OBJECTIVE:To evaluate the treatment effect of posterior pedicle screw mono-segmental internal fixation for treatment of the type AO-C1 thoracolumbar vertebrae fracture-dislocations. METHODS:From January 2008 to December 2013, 17 cases of type AO-C1 thoracolumbar fracture-dislocation were folowed up. Al patients were treated with one-stage posterior open reduction and pedicle screw-rod fixation. Of them, eight cases received four screws and two rods for single-segment fixation in upper and lower vertebrae adjacent to intervertebral space after dislocation (4-screw 2-rod group). Nine cases received eight screws and two rods for multiple-segment fixation in the upper and lower vertebrae adjacent to intervertebral space after dislocation (8-screw 2-rod group). Operative time and intraoperative blood loss were compared between the two groups. The Cobb’s angle was measured on lateral X-ray film of two groups preoperatively and 1 week postoperatively and during the final folow-up. The neurological function was evaluated by Frankel classification. The visual analogue scale was adopted to assess the degree of low back pain. RESULTS AND CONCLUSION:Patients were folowed up for 1 to 5 years. Significant differences were detected in the operative time between the two groups, and operative time was better in the 4-screw 2-rod group than in the 8-screw 2-rod group (P < 0.05). No significant difference was found in intraoperative blood loss between the two groups. The deformity of fracture-dislocation had been corrected, and the
