    Full Text Available Synthetic aperture radar polarimetry (PolSAR and polarimetric decomposition techniques have proven to be useful tools for wetland mapping. In this study we classify reed belts and monitor their phenological changes at a natural lake in northeastern Germany using dual-co-polarized (HH, VV TerraSAR-X time series. The time series comprises 19 images, acquired between August 2014 and May 2015, in ascending and descending orbit. We calculated different polarimetric indices using the HH and VV intensities, the dual-polarimetric coherency matrix including dominant and mean alpha scattering angles, and entropy and anisotropy (normalized eigenvalue difference as well as combinations of entropy and anisotropy for the analysis of the scattering scenarios. The image classifications were performed with the random forest classifier and validated with high-resolution digital orthophotos. The time series analysis of the reed belts revealed significant seasonal changes for the double-bounce–sensitive parameters (intensity ratio HH/VV and intensity difference HH-VV, the co-polarimetric coherence phase and the dominant and mean alpha scattering angles and in the dual-polarimetric coherence (amplitude, anisotropy, entropy, and anisotropy-entropy combinations; whereas in summer dense leaves cause volume scattering, in winter, after leaves have fallen, the reed stems cause predominately double-bounce scattering. Our study showed that the five most important parameters for the classification of reed are the intensity difference HH-VV, the mean alpha scattering angle, intensity ratio HH/VV, and the coherence (phase. Due to the better separation of reed and other vegetation (deciduous forest, coniferous forest, meadow, winter acquisitions are preferred for the mapping of reed. Multi-temporal stacks of winter images performed better than summer ones. The combination of ascending and descending images also improved the result as it reduces the influence of the sensor

    Replica-exchange enveloping distribution sampling (RE-EDS) allows the efficient estimation of free-energy differences between multiple end-states from a single molecular dynamics (MD) simulation. In EDS, a reference state is sampled, which can be tuned by two types of parameters, i.e., smoothness parameters(s) and energy offsets, such that all end-states are sufficiently sampled. However, the choice of these parameters is not trivial. Replica exchange (RE) or parallel tempering is a widely applied technique to enhance sampling. By combining EDS with the RE technique, the parameter choice problem could be simplified and the challenge shifted toward an optimal distribution of the replicas in the smoothness-parameter space. The choice of a certain replica distribution can alter the sampling efficiency significantly. In this work, global round-trip time optimization (GRTO) algorithms are tested for the use in RE-EDS simulations. In addition, a local round-trip time optimization (LRTO) algorithm is proposed for systems with slowly adapting environments, where a reliable estimate for the round-trip time is challenging to obtain. The optimization algorithms were applied to RE-EDS simulations of a system of nine small-molecule inhibitors of phenylethanolamine N-methyltransferase (PNMT). The energy offsets were determined using our recently proposed parallel energy-offset (PEOE) estimation scheme. While the multistate GRTO algorithm yielded the best replica distribution for the ligands in water, the multistate LRTO algorithm was found to be the method of choice for the ligands in complex with PNMT. With this, the 36 alchemical free-energy differences between the nine ligands were calculated successfully from a single RE-EDS simulation 10 ns in length. Thus, RE-EDS presents an efficient method for the estimation of relative binding free energies.

    The main objective of this paper is to evaluate the role of hydraulic retention time (HRT) and granular medium in faecal coliform (FC) and somatic coliphage (SC) removal in tertiary reed beds. Experiments were carried out in a pilot plant with four parallel reed beds (horizontal subsurface flow constructed wetlands), each one containing a different type of granular medium. This pilot plant is located in a wastewater treatment plant in Montcada i Reixac, near Barcelona, in northeastern Spain. The microbial inactivation ratios obtained in the different beds are compared as a function of three selected HRTs. Secondary effluent from the wastewater treatment plant was used as the influent of the pilot system. The microbial inactivation ratio ranged between 0.1 and 2.7 log-units for FC and from 0.5 to 1.7 log-units for SC in beds with coarser granular material (5-25mm), while it ranged between 0.7 and 3.4 log-units for FC and from 0.9 to 2.6 log-units for SC in the bed with finer material (2-13mm). HRT and granular medium are both key factors in microbial removal in the tertiary reed beds. The microbial inactivation ratio rises as the HRT increases until it reaches a saturation value (in general at an HRT of 3 days). The value of the microbial inactivation ratio at the saturation level depends on the granular medium contained in the bed. The specific surface area necessary to reach 2-3 log-units of FC and SC is approximately 3m(2)/person-equivalent.

  6. Conversations with Miss Jane

    Full Text Available Considering the wide range of conversations in the autobiography, this essay will attempt to appraise the importance of these verbal exchanges in relation to the overall narrative structure of the book and to the prevalent oral tradition in Louisiana culture, as both an individual and communal expression. The variety of circumstances, the setting and staging, the interlocutors , and the complex intersection of time and place, of stories and History, will be examined; in these conversations with Miss Jane many actors participate, from  the interviewer-narrator, to most characters; even the reader becomes involved.Speaking, hearing, listening, keeping silent is an elaborate ritual that performs many functions; besides conveying news or rumors, it imparts information on the times and on the life of a “representative” woman whose existence - spanning a whole century- is both singular and emblematic. Most importantly this essay will analyse the resonance of an eventful and often dramatic era on her sensibility and conversely show how her evolving sensibility informs that history and draws attention to aspects that might have passed unnoticed or be forever silenced. Jane’s desire for liberty and justice is often challenged as she faces the possibilities of life or death.Conversations build up a complex, often contradictory, but compelling portrait: torn between silence and vehemence, between memories and the urge to meet the future, Jane summons body and mind to find her way through the maze of a fast changing world; self-willed and obstinate she claims her right to speak, to express with wit and wisdom her firm belief in the word, in the ability to express deep seated convictions and faith and a whole array of feelings and emotions.

    Full Text Available Abstract Background This paper describes the theory and implementation of a new software tool, called Jane, for the study of historical associations. This problem arises in parasitology (associations of hosts and parasites, molecular systematics (associations of orderings and genes, and biogeography (associations of regions and orderings. The underlying problem is that of reconciling pairs of trees subject to biologically plausible events and costs associated with these events. Existing software tools for this problem have strengths and limitations, and the new Jane tool described here provides functionality that complements existing tools. Results The Jane software tool uses a polynomial time dynamic programming algorithm in conjunction with a genetic algorithm to find very good, and often optimal, solutions even for relatively large pairs of trees. The tool allows the user to provide rich timing information on both the host and parasite trees. In addition the user can limit host switch distance and specify multiple host switch costs by specifying regions in the host tree and costs for host switches between pairs of regions. Jane also provides a graphical user interface that allows the user to interactively experiment with modifications to the solutions found by the program. Conclusions Jane is shown to be a useful tool for cophylogenetic reconstruction. Its functionality complements existing tools and it is therefore likely to be of use to researchers in the areas of parasitology, molecular systematics, and biogeography.

    Two pipeline (255,233) RS decoders, one a time domain decoder and the other a transform domain decoder, use the same first part to develop an errata locator polynomial .tau.(x), and an errata evaluator polynominal A(x). Both the time domain decoder and transform domain decoder have a modified GCD that uses an input multiplexer and an output demultiplexer to reduce the number of GCD cells required. The time domain decoder uses a Chien search and polynomial evaluator on the GCD outputs .tau.(x) and A(x), for the final decoding steps, while the transform domain decoder uses a transform error pattern algorithm operating on .tau.(x) and the initial syndrome computation S(x), followed by an inverse transform algorithm in sequence for the final decoding steps prior to adding the received RS coded message to produce a decoded output message.

  14. The History of Miss Jane Pittman

    2006-05-01

    Full Text Available This paper explores the ways in which Ernest J. Gaines uses fiction in The Autobiography of Miss Jane Pittman to write a history of the African American from 1861 to 1961. The “Introduction” sets the novel going, but its direction has already been given in the unusual dedication to his grandmother, stepfather and aunt “who did not walk a day in her life but who taught me the importance of standing” (Gaines iv. The significance for Gaines is that what happened a hundred years ago is part of his present-day lived life.The nineteenth-century novel was possessed by history, and white nineteenth-century novelists found their great subject in the war of European nations that was fought between 1799 and 1815. But that was not an American war nor was it an African American war. For Gaines, the war that makes the great turning point of a nation and a people is the American Civil War, fought from 1861 to 1865. It resulted in a moment of history after which life would not be the same. However, one of the main points that Gaines makes about that great turning point in history is that everything changed and nothing changed. And his main fictional device to establish that truth is to tell the history of the hundred years since Emancipation as the story of one woman. Her autobiography becomes an ethno-biography.The continuity forwards from 1861 is given through the life of one woman, but Gaines’s uses another device to provide a continuity backwards from 1861. The young man who wants to get Miss Jane Pittman’s story upsets her with his persistence: “What you want know about Miss Jane for?’ Mary said. ‘I teach history,’ I said. ‘I’m sure her life’s story can help me explain things to my students.’ ‘What’s wrong with them books you already got?’ Mary said. ‘Miss Jane is not in them,’ I said” (Gaines v. Ernest J. Gaines wrote at a time when historians finally began to recognize that they could get no true history of the

    This paper investigates the sound production in a system made of a bore coupled with a reed valve. Extending previous work (Debut, 2004), the input impedance of the bore is projected on the modes of the air column. The acoustic pressure is therefore calculated as the sum of modal components. The airrrflow blown into the bore is modulated by reed motion, assuming the reed to be a single degree of freedom oscillator. Calculation of self-sustained oscillations controlled by time-varyi...

    Today, no other classic novelist has the popularity or power of Jane Austen, and in 2013 the world will celebrate 200 years of her comic masterpiece Pride and Prejudice. Her millions of fans have an abiding fascination with all aspects of her life, including her health and the cause of her death. This historical ophthalmic study of Jane Austen, based on very incomplete medical bibliographic data, finds that she had a mild ocular surface disorder from age 23. This disorder did not significantly impact on her visual performance for writing. There are many references to eyes in her novels, but Jane's eyes and those of her characters cannot contribute further to the debate around the cause of her death at age 41.

  1. Aerodynamic excitation and sound production of blown-closed free reeds without acoustic coupling: The example of the accordion reed

    Science.gov (United States)

    Ricot, Denis; Caussé, René; Misdariis, Nicolas

    2005-04-01

    The accordion reed is an example of a blown-closed free reed. Unlike most oscillating valves in wind musical instruments, self-sustained oscillations occur without acoustic coupling. Flow visualizations and measurements in water show that the flow can be supposed incompressible and potential. A model is developed and the solution is calculated in the time domain. The excitation force is found to be associated with the inertial load of the unsteady flow through the reed gaps. Inertial effect leads to velocity fluctuations in the reed opening and then to an unsteady Bernoulli force. A pressure component generated by the local reciprocal air movement around the reed is added to the modeled aerodynamic excitation pressure. Since the model is two-dimensional, only qualitative comparisons with air flow measurements are possible. The agreement between the simulated pressure waveforms and measured pressure in the very near-field of the reed is reasonable. In addition, an aeroacoustic model using the permeable Ffowcs Williams-Hawkings integral method is presented. The integral expressions of the far-field acoustic pressure are also computed in the time domain. In agreement with experimental data, the sound is found to be dominated by the dipolar source associated by the strong momentum fluctuations of the flow through the reed gaps. .

    Full Text Available Reed Solomon (RS codes is a mechanism to detect and correct burst of errors in data transmission and storage systems. It provides a solid introduction to foundation mathematical concept of Galois Field algebra and its application. With the development of digital hardware technology, the RS concepts were brought into reality, i.e. the implementation of RS codec chips. This paper presents the development steps of a generic RS encoder using VHDL. The encoder is able to handle generic width of data, variable length of information, number of error as well as variable form of primitive polynomial and generator polynomial used in the system. The design has been implemented for FPGA chip Xilinx XC3S200-5FT256 and has a better performance than commercially available equivalent encoder.

  4. Saving reed lands by giving economic value to reed

    Directory of Open Access Journals (Sweden)

    F.W. Croon

    2014-07-01

    Full Text Available Discussions about the need for renewable energy, the need for nature conservation, the need to double the world’s food production to eliminate hunger, the need to reduce carbon dioxide emission, and the wish to reduce dependency on dwindling oil resources, show that these issues are intimately related and sometimes mutually exclusive. The use of food crops for the production of renewable fuels has resulted in the energy vs. food debate; the use of scarce land and fresh water for the dedicated production of biomass conflicts with food production and nature conservation; the collection of harvest residues and forest wastes as biomass to produce renewable fuels is complex and leaves a CO2 footprint. The several species of reed that grow naturally in deltas, river plains etc. can provide large amounts of biomass but are hardly mentioned in the debates. Harvesting reed does not threaten the nature and the natural functions of reed lands, which are carbon neutral or carbon dioxide sinks. Reed production does not need extensive infrastructure or complex cultivation and does not compete with food production for land and fresh water. Reed lands in many places are under threat of reclamation for economic activities and urbanisation. This trend can be countered if reed is seen to have a proven economic value. In this article I argue that giving a sustainable economic value to reed lands can only be realised if the exploitation is recognised as being environmentally acceptable, commercially feasible and a source of economic gains for all stakeholders. Commercial feasibility can be achieved under present economic conditions only if a reliable supply of considerable volumes of reed at a limited price can be guaranteed.

    Full Text Available In the maze of Austen’s ever-expanding textuality – with its prequels, sequels, rewritings and adaptations – it may be worth paying attention to an unpretentious little book by Shannon Hale titled Austenland (2007. The story is about the adventures of a New Yorker thirty-something with a name that says it all: Jane. Being obsessed with Mr Darcy as played by Colin Firth, she decides to be healed by her excessive Austenian fantasies (or rather to indulge in them for the last time by spending all her savings on a English Regency Theme park that promises to offer Janeites a real full immersive Austen experience. What interests me in this post-Austenian story is the embedded discourse of leisure and tourism in the age of participatory culture, when an everywoman like Jane brings to the fore the need to be more involved in re-creative activities that are triggered by reading Austen’s novels.

    Full Text Available We propose to discuss the role of filmic narratives with the book as an object of representation in the context of the imaginary of shapes and types of knowledge, of ways of reading organization and of practices that have the book as object. Finally, we have the dialogical perspective of the works, its time, the subject readers and its context. For this project, we bring the filmic text The Jane Austen Book Club (2007, based on a book (The Jane Austen book club by Karen Joy Fowler, which focuses on personal and intimate dramas from people at different times of sharing, unfolding for six months, and that presents individual experiences which are mixed with the characters’ plots from the books of the English author. We highlight in the film, book and reading as narrative elements, characters accomplices of small dramas. In The Jane Austen Book Club, we perform an extrapolation in order to put the two moments - the performance and reading - in the practices developed by the participants of the club. They find the work of Austen in individual reading and in the performance that puts everyone in a continuous space of action and transformation. We believe, finally, that individual reading and the club meetings make it possible to think of the reception (individual reading and performance (reading/collective analysis in a combination that allows a constant revitalization of the work, in the case of Jane Austen.

    2011-12-01

    The Regional Energy Deployment System (ReEDS) is a deterministic optimization model of the deployment of electric power generation technologies and transmission infrastructure throughout the contiguous United States into the future. The model, developed by the National Renewable Energy Laboratory's Strategic Energy Analysis Center, is designed to analyze the critical energy issues in the electric sector, especially with respect to potential energy policies, such as clean energy and renewable energy standards or carbon restrictions. ReEDS provides a detailed treatment of electricity-generating and electrical storage technologies and specifically addresses a variety of issues related to renewable energy technologies, including accessibility and cost of transmission, regional quality of renewable resources, seasonal and diurnal generation profiles, variability of wind and solar power, and the influence of variability on the reliability of the electrical grid. ReEDS addresses these issues through a highly discretized regional structure, explicit statistical treatment of the variability in wind and solar output over time, and consideration of ancillary services' requirements and costs.

  9. Jane Austen on love and pedagogical power.

    Science.gov (United States)

    Fessenbecker, Patrick

    2011-01-01

    This essay notes initially recent prominence of theories of pedagogy that attempt to "de-mystify" it and reveal troubling power relations, and their subsequent contention that love is impossible in the student-teacher relationship. "Pedagogical" interpretations of Jane Austen's fiction, however, see pedagogy as essential to love. I argue that this is so precisely because of the power dynamics involved; drawing on Jessica Benjamin's psychoanalytic interpretation of G. W. F. Hegel's analysis of the "Lord-Bondsman," I suggest that Austen portrays the loving relationship as inherently involving the occupation and subsequent exchange of roles as superior and inferior, incarnated as "teacher" and "student."

A highly accurate RPIS for SMART is required because the reactivity of a nuclear core for a small modular reactor is more sensitive than the commercial ones. In this study, the effect of positioning direction of the reeds in a reed switch for the CRDM RPIS has been studied using the electromagnetic FE analysis. It is found that the positioning direction of the reeds slightly but not significantly affects the formation of attraction.

    Full Text Available Che Jane Austen, dopo essere giunta a una incontrastata canonizzazione nel pantheon della letteratura occidentale, abbia recentemente intrapreso una   trionfante ascesa nell’ambito della cultura popolare è ormai “una verità universalmente riconosciuta”.   Il saggio analizza i modi, le forme, i supporti e i canali attraverso cui Jane Austen e i suoi testi narrativi (con particolare riferimento a Pride and Prejudice sono usciti dal cerchio tutto sommato ristretto dell’accademia, dei curricola universitari e dei lettori di professione, per entrare in uno spazio che è quello di YouTube, delle fan communities, della musica pop, dei blog, del romanzo rosa o dell’horror; i percorsi grazie ai quali sono diventati parte delle mitologie popolari del XXI secolo e al tempo stesso un brand di successo intorno al quale ruota una fitta rete di interessi economici (industria cinematografica e televisiva, turismo, editoria…, capace di catalizzare (e sfruttare desideri, proiezioni, aspettative di nuove tipologie di lettori; le inedite modalità di ricezione che caratterizzano questo fenomeno, e soprattutto la fan fiction, situata al punto di convergenza o di frizione tra diversi media (letteratura, cinema, televisione, web e media digitali in genere, tra produttori e consumatori, tra lettura e scrittura, tra strategie commerciali delle corporation e autarchia dei fan, tra “alto” e “basso”. Si tratta di un insieme di trasformazioni che scuote alle fondamenta le nostre consuetudini e le nostre credenze in quanto studiosi di letteratura: da una parte, emerge una nuova configurazione della testualità, euforica, rizomatica, molteplice, che si fa beffe di qualunque metafisica dell’originale e realizza in modo perverso alcune celebri utopie critiche; dall’altra, il caso Austen porta alla luce in maniera emblematica le contraddizioni latenti in qualunque processo di democratizzazione della cultura.

    2009-08-01

    In a 3-year-study, we analysed the population dynamics of the reed pathogen Pythium phragmitis and other reed-associated oomycetes colonizing fresh and dried reed leaves in the littoral zone of a large lake. Oomycete communities derived from internal transcribed spacer clone libraries were clearly differentiated according to substrate and seasonal influences. In fresh leaves, diverse communities consisting of P. phragmitis and other reed-associated pathogens were generally dominant. Pythium phragmitis populations peaked in spring with the emergence of young reed shoots, and in autumn after extreme flooding events. In summer it decreased with falling water levels, changing water chemistry and rising temperatures. Another Pythium species was also highly abundant in fresh leaves throughout the year and might represent a new, as-yet uncultured reed pathogen. In dried leaves, reed pathogens were rarely detected, whereas saprophytic species occurred abundantly during all seasons. Saprophyte communities were less diverse, less temperature sensitive and independent of reed development. In general, our results provide evidence for the occurrence of highly specialized sets of reed-associated oomycetes in a natural reed ecosystem. Quantitative analyses (clone abundances and quantitative real-time PCR) revealed that the reed pathogen P. phragmitis is particularly affected by changing water levels, water chemistry and the stage of reed development.

  19. The Anonymous Jane Austen: Duelling Canons

    Directory of Open Access Journals (Sweden)

    Edward Copeland

    2017-12-01

    Full Text Available This essay initially addresses some theoretical concepts such as adaptation and appropriation. I intend to analyze how Jane Austen herself indulged in her own appropriations from the woman’s canon, in particular through a story entitled Guilt Pursued by Conscience, a tale she found in the “Lady’s Magazine” of 1802. I will show that this tale that claimed Austen’s particular attention was re-appropriated in Emma (although in the broadest sense of parody and, to a lesser extent, in Sense and Sensibility. The second part of the essay, instead, will move on to analyze how novelists of the generation that followed Austen felt free to import dialogue, characters, and plots from Austen’s works, showing no obligation to their source, just as she had done with the “Lady’s” tale. I will mention and comment on a series of novels, especially from the silver fork school, that draw from Austen’s plot, characters and happenings without acknowledging their legacy to their predecessor.

  1. An exploration of common reed (Phragmites australis bioenergy potential in North America

    Directory of Open Access Journals (Sweden)

    2014-10-01

    Full Text Available In North America, reed (Phragmites australis is typically considered to be a weed although it provides important ecosystem services. Small, sparse, patchy or mixed reedbeds are more suitable as habitat for many species than extensive dense reedbeds, whose habitat functions can be enhanced by the selective removal of biomass. We propose that above-ground reed biomass could be harvested for bioenergy, at the same time improving habitat for biodiversity by thinning or fragmenting the more extensive reedbeds. Biofuel pellets manufactured from reeds harvested at Montréal (Canada had moisture content 6.4 %, energy content 16.9 kJ g-1 (dry mass, ash content 3.44 %, and chloride content 1962 ppm. Thus, reed as a material for fuel pellet manufacture is similar to switchgrass (Panicum virgatum, which is commonly cultivated for that purpose and requires higher inputs than harvested wild reed. We discuss these findings in the context of environmental considerations and conclude that the bioenergy potential of reed could most expediently be realised in North America by combining material harvested from the widespread spontaneously occurring reedbeds with organic waste from other sources to create mixed biofuels. However, reeds with high levels of chlorine, sulphur or metals should not be burned to avoid air pollution or equipment damage unless these problems are mitigated by means of appropriate season of harvest, equipment, combustion regime, or use of a mixed feedstock.

  2. Jane Austen and Addison's disease: an unconvincing diagnosis.

    Science.gov (United States)

    White, K G

    2009-12-01

    Jane Austen's letters describe a two-year deterioration into bed-ridden exhaustion, with unusual colouring, bilious attacks and rheumatic pains. In 1964, Zachary Cope postulated tubercular Addison's to explain her symptoms and her relatively pain-free illness. Literary scholars later countered this posthumous diagnosis on grounds that are not well substantiated, while medical authors supported his conclusion. Important symptoms reported by contemporary Addison's patients-mental confusion, generalised pain and suffering, weight loss and anorexia-are absent from Jane Austen's letters. Thus, by listening to the patient's perspective, we can conclude it is unlikely that Addison's disease caused Jane Austen's demise. Disseminated bovine tuberculosis would offer a coherent explanation for her symptoms, so that Cope's original suggestion of infective tuberculosis as the cause of her illness may have been correct.

  3. "Young ladies are delicate plants": Jane Austen and Greenhouse Romanticism.

    Science.gov (United States)

    Lynch, Deidre Shauna

    2010-01-01

    By annotating how in Mansfield Park and Northanger Abbey Jane Austen tracks between the novelist's domain and the naturalist's, this essay seeks to unsettle some entrenched assumptions about her relationship to realism—and the ideological work of naturalization that realism is said to sponsor—as well as to romanticism. Austen's era, which we customarily identify as the time of a romantic return to nature, was marked by conflicts over what nature did and did not include—conflicts between, in the parlance of the period, "the botanist" and "the florist," between an account of nature as that which was given and an account of nature as that which (as with the modern nurseryman's new hybrids and luxuriants) might be manufactured. In arranging for her young heroines' stories of growing up to unfold in the "artificial climates" of modern fashionable gardening and amidst "florists' flowers," Austen deliberately works through those conflicts. She inhabits the plot of "natural development" to which she is often linked in elusively oppositional ways.

No good method exists for measuring the sludge quality with respect to drainage characteristics. A new experimental method...... has therefore been developed to measure relevant quality parameters: specific cake resistance, settling velocity and cake compressibility. It has been found that activated sludge form highly compressible cake even at the low compressive pressures obtained during drainage. Numerical simulation shows......Activated sludge is a by-product from waste water treatment plants, and the water content in the sludge is high (> 90%). Among several methods to remove the water, sludge drying reed beds are often used to dewater the sludge by drainage. There is, however, no well-defined criterion for design...

    2011-01-01

    The Microwave Rocket is a candidate for a low cost launcher system. Pulsed plasma generated by a high power millimeter wave beam drives a blast wave, and a vehicle acquires impulsive thrust by exhausting the blast wave. The thrust generation process of the Microwave Rocket is similar to a pulse detonation engine. In order to enhance the performance of its air refreshment, the air-breathing mechanism using reed valves is under development. Ambient air is taken to the thruster through reed valves. Reed valves are closed while the inside pressure is high enough. After the time when the shock wave exhausts at the open end, an expansion wave is driven and propagates to the thrust-wall. The reed valve is opened by the negative gauge pressure induced by the expansion wave and its reflection wave. In these processes, the pressure oscillation is important parameter. In this paper, the pressure oscillation in the thruster was calculated by CFD combined with the flux through from reed valves, which is estimated analytically. As a result, the air-breathing performance is evaluated using Partial Filling Rate (PFR), the ratio of thruster length to diameter L/D, and ratio of opening area of reed valves to superficial area α. An engine cycle and predicted thrust was explained.

  19. The Wheal Jane wetlands model for bioremediation of acid mine drainage

    International Nuclear Information System (INIS)

    Whitehead, P.G.; Cosby, B.J.; Prior, H.

    2005-01-01

    Acid mine drainage (AMD) is a widespread environmental problem associated with both working and abandoned mining operations. As part of an overall strategy to determine a long-term treatment option for AMD, a pilot passive treatment plant was constructed in 1994 at Wheal Jane Mine in Cornwall, UK. The plant consists of three separate systems, each containing aerobic reed beds, anaerobic cell and rock filters, and represents the largest European experimental facility of its kind. The systems only differ by the type of pretreatment utilised to increase the pH of the influent minewater (pH <4): lime dosed (LD), anoxic limestone drain (ALD) and lime free (LF), which receives no form of pretreatment. Historical data (1994-1997) indicate median Fe reduction between 55% and 92%, sulphate removal in the range of 3-38% and removal of target metals (cadmium, copper and zinc) below detection limits, depending on pretreatment and flow rates through the system. A new model to simulate the processes and dynamics of the wetlands systems is described, as well as the application of the model to experimental data collected at the pilot plant. The model is process based, and utilises reaction kinetic approaches based on experimental microbial techniques rather than an equilibrium approach to metal precipitation. The model is dynamic and utilises numerical integration routines to solve a set of differential equations that describe the behaviour of 20 variables over the 17 pilot plant cells on a daily basis. The model outputs at each cell boundary are evaluated and compared with the measured data, and the model is demonstrated to provide a good representation of the complex behaviour of the wetland system for a wide range of variables

    Full Text Available The Autobiography of Miss Jane Pittman by Ernest J. Gaines is a testimony of the black female abolitionist struggle. Its protagonist, Miss Jane Pittman, whose life covers the Civil War period (1861-1865 and the 1960s, embodies the African American women’s experience through her own story. As Ernest J. Gaines gives her the voice to relate her life experience, she reflects on her being and at the same time, she constructs her identity which reveals her heroism. Her struggle for freedom turns around her participation in the Civil War and the Civil Rights Movement. But her attempt to reach the North after the Civil War remains an important fact of her struggle. As a symbol of the black female abolitionist struggle, her “autobiography” is the voiceless African American women’s point of view.

    A new information storage and retrieval system has been developed for the Radiation Shielding Information Center (RSIC) at Oak Ridge National Laboratory to replace mainframe systems that have become obsolete. The database contains citations and abstracts of literature which were selected by RSIC analysts and indexed with terms from a controlled vocabulary. The database, begun in 1963, has been maintained continuously since that time. The new system, called JANE, incorporates automatic indexing techniques and on-line retrieval using the RSIC Data General Eclipse MV/4000 minicomputer, Automatic indexing and retrieval techniques based on fuzzy-set theory allow the presentation of results in order of Retrieval Status Value. The fuzzy-set membership function depends on term frequency in the titles and abstracts and on Term Discrimination Values which indicate the resolving power of the individual terms. These values are determined by the Cover Coefficient method. The use of a commercial database base to store and retrieve the indexing information permits rapid retrieval of the stored documents. Comparisons of the new and presently-used systems for actual searches of the literature indicate that it is practical to replace the mainframe systems with a minicomputer system similar to the present version of JANE. 18 refs., 10 figs

    The aim of this study was to test fuel blends of briquettes and chopped reed canary grass in three existing heating plants (50 kW - 500 kW) and elucidate the requirements for good performance and low emissions. In addition, the study investigated production of reed canary grass briquettes using a Polish screw press developed for straw. Some tests with a bale shredder were also undertaken. The screw press technique is of interest for reed canary grass because it is a simple technique, easy to handle, developed for small scale production, and for straw. The test with reed canary grass in this study showed that the technique worked well but that further adjustments and a longer test period are needed in order to achieve higher bulk density and mechanical strength. The test with chopped reed canary grass shows that a system with a forage harvester is slightly more effective than baling and cutting in a bale shredder. The study concluded that few existing heating plants of size 50 kW-1 MW that currently use wood fuels will be able to use reed canary grass without adjustment, conversion or replacement of the combustion equipment. Reed canary grass has 15-20 times higher ash content than wood briquettes and 2-3 times higher ash content than forest residue; the combustion equipment must be able to handle these properties. The boiler must be equipped with a continuously operating ashing system and it must be possible to move the ash bed mechanically. There is a risk of high content of unburned matter if the residence time in the boiler is too short, due to the structure and low bulk density of the reed canary grass ash. Using a blend of wood briquettes and reed canary briquettes results in lower ash content, but also affects the ash chemistry and tends to lower the initial ash fusion temperature compared to using 100 % reed canary grass. Blending chopped reed canary grass and wood chips in an existing small scale heating plant also requires measures to achieve an even fuel

    For the generation of sound, some woodwind musical instruments, e.g. oboe, bassoon, clarinet and saxophone, are provided with mouthpieces made from reeds. These reeds are the culms of Arundo donax, a tall, cane-like perennial grass. A general problem is that the material is of varying quality, yet externally differences cannot be observed. Hence, large proportions of the prepared reeds are unusable. One hypothesis is that the changes in quality are correlated with differences in the chemical and anatomical structure of the tissue. Therefore, a comparison of superior and inferior mouthpieces, used by professional musicians, was undertaken to determinate potential indicators of quality. Nuclear microprobe analysis of reeds was carried out and complemented by scanning electron and light microscopy. The elemental levels of Si, P, S, Cl, K and Ca were compared between good and poor mouthpieces using appropriate statistical tests. No statistically significant differences could be identified. Microscopical observations showed that partial occlusion of vessels by tylose formation was associated with material deemed unusable

    References to headache in Jane Austen's works, both fictional and non-fictional, and in biographical works undertaken by Austen family members have been collated. These multiple references suggest that Jane Austen used headache as a narrative device to reflect not only physiological bodily processes but also psychological states, possibly based on her own experience of headache and that of female relations and acquaintances.

  11. The mechanical spectra of deposited materials by a composite reed vibration method

    International Nuclear Information System (INIS)

    Ying, X.N.; Zhang, L.; Yuan, Y.H.

    2010-01-01

    Recently a composite reed vibration method has been designed to measure the mechanical spectra (complex Young's modulus) of materials from liquid to solid state. The mechanical spectra of materials can be obtained from a composite system consisting of a substrate reed and of materials deposited on it. In this report, two sets of formulas to calculate the mechanical spectra of deposited materials are further analyzed. The proof is given for the previous named 'approximate formulas' (labeled as Formula II). Then the composite reed vibration method can be safely used as an extension of the mechanical spectrum method of the thin solid film. At the same time, some comments are made on previous analytical formulas (labeled as Formula I). At last, more experiments with a small amount of deposited materials are performed. It is found that smaller quantity is more favorable to achieve the intrinsic mechanical spectra of deposited materials.

  12. Ambivalence and Ambiguity in The Autobiography of Miss Jane Pittman

    Directory of Open Access Journals (Sweden)

    Monica Michlin

    2006-05-01

    Full Text Available This close reading of the text highlights how Miss Jane, in her double role as protagonist and narrator, shows considerable ambivalence towards friend and foe alike, with the result that the apparently transparent ideological meaning of entire episodes is blurred by what some critics have merely put down to “conservatism.” I examine Miss Jane’s almost constant suppression of emotion, and frequent displays of ambivalence towards other black people; her ambiguous relationship to oppressive, but familiar whites like Albert Cluveau or Robert Samson; and her conflicted relation to black heroes and heroics. Is the leading character a variation on the “mammy” who has internalized racist figures of speech, and uses contradictory images that undermine black heroics and validate white oppression? Or is Gaines’s point to undo the “retrick” of heroics and of alienation alike, and, against of backdrop of constant, ordinary destruction of black lives, to cast the adult Miss Jane as a Brer Rabbit-like figure, for whom survival and resistance are both dialectically connected and opposed? Is there a contradiction between her “progress” towards resistance shown in the last section, and her metadiscursive comments in the present, and does her literally walking out of her own story give a conclusive meaning to her narrative, or does it point to the author’s not having been able to resolve the ambivalence and ambiguities within the text?

  13. Jane Doe: a cautionary tale for case reports.

    Science.gov (United States)

    Putnam, Frank W

    2014-12-01

    Historically, clinical case reports have played an essential role in the professional communication of medical and psychiatric knowledge. Case reports continue to play important roles in the initial identification of new syndromes or unusual variants of established conditions. Case reports and case series also serve to alert clinicians to preliminary evidence of the efficacy of novel treatments or adaptations to new populations. The Jane Doe Case provides a seminal example of the ethical/medico-legal dilemma arising from a patient's right to confidentiality versus the principle of independent review/replication as a necessary requirement for scientific credibility. As a result of being the subject of dueling case reports concerning the validity of her delayed recall of childhood sexual abuse, Jane Doe's identity was revealed. Consequently, she suffered significant emotional distress, bankruptcy, and the end of her career as a naval officer and aviator. Current medical journal guidelines call for protection of confidentiality of the patient's identity; yet, scientific credibility requires the possibility of an independent outside review if there are legitimate reasons to question facts or claims advanced in a case report. A potential solution is proposed as a starting point for resolving the dilemma posed for case study subjects and authors by the conflicting requirements of patient confidentiality and, if warranted, the possibility of an independent scientific review. © The Author(s) 2014.

    2009-10-15

    Sludge reed beds have been used for dewatering (draining and evapotranspiration) and mineralisation of sludge in Europe since 1988. Although reed beds are considered as a low cost and low contamination method in reducing volume, breaking down organic matter and increasing the density of sludge, it is not yet clear whether this enhanced biological treatment is suitable for degradation of organic micro-pollutants such as personal care products. Within this project the effect of biological sludge treatment in a reed bed on reducing the concentrations of the fragrances HHCB, AHTN, OTNE was studied as on the bactericide Triclosan. Additionally, the capacity of different macrophytes species to affect the treatment process was examined. Three different macrophyte species were compared: bulrush (Typha latifolia), reed (Phragmites australis) and reed canary grass (Phalaris arundinacea). They were planted into containers (lysimeters) with a size of 1 m x 1 m x 1 m which were filled with 20 cm gravel at the bottom and 50 cm sludge on top, into which the macrophytes were planted. During the twelve months experiment reduction of 20-30% for HHCB and AHTN, 70% for Triclosan and 70% for OTNE were determined under environmental conditions. The reduction is most likely due to degradation, since volatilization, uptake into plants and leaching are insignificant. No difference between the containers with different macrophyte species or the unplanted containers was observed. Considering the usual operation time of 10 years for reed beds, an assessment was made for the whole life time.

  16. 39th annual Reed rig census

    International Nuclear Information System (INIS)

    Crowhurst, M.E.; Fitts, R.L.

    1991-01-01

    This paper reports on cutbacks in U.S. exploration and development drilling during the first half of 1991 which squeezed most of the optimism out of the drilling industry. Just how rough the year has been is underscored by the results of this year's rig census. The number of rotary rigs available for U.S. drilling declined by only 69 units (3%) during the past 12 months. But despite those withdrawals from competition, only 66% of the remaining rigs were working at the time the census was taken. Results of the 1991 census contrasted sharply with the stability and optimism that seemed apparent a year ago when 72% of the available rig fleet met the census definition of active. At that time, the mini-boom in horizontal drilling coupled with tax-credit- driven gas drilling led to a relatively high rig utilization rate and suggested that rig supply and demand might be close to an economically acceptable balance. However, it quickly became apparent in early 1991 that industry optimism was unjustified. Horizontal drilling began to drop and the lowest natural gas prices in 12 years triggered rapid declines in gas drilling. Although oil prices have been relatively stable and above $18 per bbl since January 1989, most major operators have concluded that a better return on investment can be had outside the U.S. and have drastically cut their domestic drilling budgets. These factors, combined with softened energy demand from the worldwide recession, further slowed U.S. drilling. The long awaited balance between rig supply and demand has seemingly slipped away. The 1991 Reed rig census describes an industry facing several more rough years. Details of this year's census include: The available U.S. fleet now stands at 2,251 rigs, down by 69 from the 2,320-unit total in 1990, and the lowest since 1976. Rigs meeting the census definition of active numbered 1,485, down 192 (11.4%) from the 1,677 active rigs counted a year earlier

    Full Text Available This paper analyzes the interesting technique of adaptation of the film Becoming Jane, a biopic on the life of Jane Austen, released in 2007. Loosely based on Jon Spence's biography Becoming Jane Austen, the film faces the problem of the scarcity of information on Jane Austen's life through a technique that, if not original nor always satisfying, is nevertheless worth being studied. By recurring to the character descriptions and the anecdotes narrated in the novels, the film (and Spence's book too "fills in the blanks" in Austen's life by adding touches of romance with questionable historical accuracy and fictionalizes the writer's biography in order to adapt it to the stereotype of modern romantic film heroines.

    We consider a list decoding algorithm recently proposed by Pellikaan-Wu for q-ary Reed-Muller codes RM{sub q}({ell}, m, n) of length n {le} q{sup m} when {ell} {le} q. A simple and easily accessible correctness proof is given which shows that this algorithm achieves a relative error-correction radius of {tau} {le} (1-{radical}{ell}q{sup m-1}/n). This is an improvement over the proof using one-point Algebraic-Geometric decoding method given in. The described algorithm can be adapted to decode product Reed-Solomon codes. We then propose a new low complexity recursive aJgebraic decoding algorithm for product Reed-Solomon codes and Reed-Muller codes. This algorithm achieves a relative error correction radius of {tau} {le} {Pi}{sub i=1}{sup m} (1 - {radical}k{sub i}/q). This algorithm is then proved to outperform the Pellikaan-Wu algorithm in both complexity and error correction radius over a wide range of code rates.

    Full Text Available Constructed wetlands are a popular form of waste-water treatment that have proliferated across Europe and the rest of the world in recent years as an environmentally conscious form of waste water treatment. The ability to monitor the conditions in the bed and control input factors such as heating and aeration may extend the lifetime of the reed bed substantially beyond the ten year lifetime normally reached. The Autonomous Reed Bed Installation (ARBI project is an EU FP7 initiative to develop a reed bed with automated control over input parameters based on readings taken from embedded sensors. Automated remedial action may improve bed treatment efficiency, and prolong the life of the bed and avoiding the need to refurbish the bed, which is both time consuming and costly. One critical parameter to observe is the clog state of the reed bed, as this can severely impact on the efficiency of water treatment to the point of the bed becoming non-operable. Magnetic resonance (MR sensors can be a powerful tool in determining clogging levels, and has previously been explored in the literature. This work is based on a conference paper (2nd International Conference "Water resources and wetlands", 2014 and details magnetic sensors suitable for long-term embedding into a constructed wetland. Unlike previous studies this work examines a probe embedded into a wetland.

  5. Reed as a gasification fuel: a comparison with woody fuels

    Directory of Open Access Journals (Sweden)

    S. Link

    2013-10-01

    Full Text Available Reed and coniferous wood can be used for energy production via thermochemical conversion, for instance by gasification. The rate-determining step of the gasification process is the reaction between the char and the gaseous environment in the gasifier, whose rate depends on variables such as pressure, temperature, particle size, mineral matter content, porosity, etc. It is known that reactivity can be improved by increasing the temperature, but on the other hand the temperature achieved in the reactor is limited due to the ash fusion characteristics. Usually, the availability of reed as a fuel is locally modest and, therefore, it must be blended with other fuels such as wood. Blending of fuels brings together several problems relating to ash behaviour, i.e. ash fusion issues. Because there is no correlation between the ash fusion characteristics of biomass blends and their individual components, it is essential to carry out prior laboratory-scale ash fusion tests on the blends. This study compares the reactivity of reed and coniferous wood, and the ash fusion characteristics of blends of reed and coniferous wood ashes. When compared with Douglas fir and reed chars, pine pellets have the highest reactivity. Reed char exhibits the lowest reactivity and, therefore, it is advantageous to gasify reed alone at higher gasification temperatures because the ash fusion temperatures of reed are higher than those of woody fuels. The ash produced by reed and wood blends can melt at lower temperatures than ash from both reed and wood gasified separately. Due to this circumstance the gasification temperature should be chosen carefully when gasification of blends is carried out.

    Among the essential amino acids, phenylalanine, tryptophan, and tyrosine are aromatic amino acids which are synthesized by the shikimate pathway in plants and bacteria. Herbicide glyphosate can inhibit the biosynthesis of these amino acids. So, identification of the gene tolerant to glyphosate is very important. It has been shown that the common reed or Phragmites australis Cav. (Poaceae) is relatively tolerant to glyphosate. The aim of the current research is identification, cloning, sequencing, and registering of partial aro A gene of the common reed P. australis. The partial aro A gene of common reed (P. australis) was cloned in Escherichia coli and the amino acid sequence was identified/determined for the first time. This is the first report for isolation, cloning, and sequencing of a part of aro A gene from the common reed. A 670 bp fragment including two introns (86 bp and 289 bp) was obtained. The open reading frame (ORF) region in part of gene was encoded for 98 amino acids. Alignment showed high similarity among this region with Zea mays (L.) (Poaceae) (94.6%), Eleusine indica L. Gaertn (Poaceae) (94.2%), and Zoysia japonica Steud. (Poaceae) (94.2%). The alignment of amino acid sequence of the investigated part of the gene showed a homology with aro A from several other plants. This conserved region forms the enzyme active site. The alignment results of nucleotide and amino acid residues with related sequences showed that there are some differences among them. The relative glyphosate tolerance in the common reed may be related to these differences.

    Alexander Marcet was an authority on urinary calculi and their analysis when few medical practitioners appreciated the usefulness of chemistry in the explanation and treatment of disease. In An Essay on The Chemical History and Medical Treatment of Calculous Disorders, he described the discovery of an xanthine stone. He drew line illustrations of simple chemical apparatus useful for bedside analysis. His microtechnique used drops of solution and pinhead pieces of calculi; reagents were acids and alkalies and the blowpipe in conjunction with a small alcohol lamp. He reported the earliest description of a disorder later named "alcaptonuria". Marcet's work and that of a few others, on the chemical composition of urine and calculi, laid the foundations of our present knowledge. Between 1807 and 1820, his lectures to the medical students at Guy's Hospital were illustrated by experiments. Jane Haldimand Marcet wrote the very popular CONVERSATIONS: on Chemistry (16 editions in Great Britain). Her book dominated elementary chemical instruction during the first half of the 19th century. She followed Lavoisier's scheme of classification and explained chemical reactions in terms of affinity, aggregation, gravitation, and repulsion. Her advocacy that experimentation accompany lecture was new. The availability of serious scientific education in the new women's academies set the stage for increasing women's involvement in science. She also published a series of CONVERSATIONS: The topics were Political Economy, Natural Philosophy, and Vegetable Physiology.

    Reed (typha) mill was converted to liquid products by using organic solvents (methanol, ethanol and acetone) with catalysts (% 10 NaOH and ZnCl{sub 2}) and without catalyst in an autoclave at temperatures of 533, 553, and 573 K. The liquid products were extracted by liquid-liquid extraction [DSA1] (benzene and diethyl ether). The yields from supercritical methanol, ethanol and acetone conversions were 36.2, 24.5, and 55.1%, respectively, at 573 K. In the catalytic runs with methanol and ethanol extracts were 46.3 and 35.5% (for NaOH catalyst) and 51.8 and 38.5% (for ZnCl{sub 2} catalyst) respectively, at 573 K. The yields from supercritical methanol were increased from 38.2 to 52.4% as the temperature was increased from 533 to 573 K in the catalytic run. (Author)

    As the volume of data acquired by space-based sensors increases, mission data compression/decompression and forward error correction code processing performance must likewise scale. This competency development effort was explored using the General Purpose Graphics Processing Unit (GPGPU) to accomplish high-rate Rice Decompression and high-rate Reed-Solomon (RS) decoding at the satellite mission ground station. Each algorithm was implemented and benchmarked on a single GPGPU. Distributed processing across one to four GPGPUs was also investigated. The results show that the GPGPU has considerable potential for performing satellite communication Data Signal Processing, with three times or better performance improvements and up to ten times reduction in cost over custom hardware, at least in the case of Rice Decompression and Reed-Solomon Decoding.

    It is shown that Reed-Solomon (RS) codes can be decoded by using a fast Fourier transform (FFT) algorithm over finite fields GF(F sub n), where F sub n is a Fermat prime, and continued fractions. This new transform decoding method is simpler than the standard method for RS codes. The computing time of this new decoding algorithm in software can be faster than the standard decoding method for RS codes.

    In the history of detective stories, Sherlock Holmes and Miss Jane Marple remain as two of the most prominent fig-ures. Focusing on the two detectives' images, personality traits, detective strategies as well as settings of the stories, this study ex-amines the grounds that magnetize readers.The purpose of this research is to inquire into readers' orientations to Sherlock Holm-es and Miss Jane Marple, and to investigate the causes for their views. To fulfill that purpose, a questionnaire was designed and dis-tributed. Sherlock Holmes and Miss Jane Marple prove themselves to be successful detectives. Both of them have distinct images and personality traits as well as plausible detective strategies. The settings, combining reality with imagination, also play a dispens-able role. Besides, reasons given by students who disbelieve that they are real persons fail to convince.

    In"Jane Eyre", Charlotte Bronte's masterpiece the heroine, Jane Eyre has fully reflected her self-esteem, equality, and pure personality, which are also reflected in her concept of love vividly. However, Thomas Hardy's Tess is poor and kind, but she does not have a complete love like Jane Eyre, and she is described by his criticism of the old moral character with good vir-tues in the traditional sense. She is a new image of modern feminism who suffered from the old moral sense and gradually has re-volt consciousness. From the feminism viewpoint, this paper attempts to analysis the causes of their different fate from different points and reveal the impact of social background on their fates.

  15. Odd complaints and doubtful conditions: norms of hypochondria in Jane Austen and Catherine Belling.

    Science.gov (United States)

    Nelson, James Lindemann

    2014-06-01

    In her final fragmentary novel Sanditon, Jane Austen develops a theme that pervades her work from her juvenilia onward: illness, and in particular, illness imagined, invented, or self-inflicted. While the "invention of odd complaints" is characteristically a token of folly or weakness throughout her writing, in this last work imagined illness is also both a symbol and a cause of how selves and societies degenerate. In the shifting world of Sanditon, hypochondria is the lubricant for a society bent on turning health into a commodity. As a result, people's rationality and their moral character come under attack. Catherine Belling's recent subtle study, A Condition of Doubt: The Meanings of Hypochondria, unveils hypochondria's discursive and cultural character. Running sharply against the tenor of Austen's treatment, however, she argues in defense of the rationality of hypochondriacs; the notion that the condition may involve morally significant defects is not entertained; any connection to the commercialization of health care is muted. Here, I contrast Austen's morally and epistemically negative rendering of her hypochondriacal characters in Sanditon with Belling's efforts to create a sympathetic understanding of people with hypochondria. I will argue that, despite time gaps and genre differences, joint consideration of these texts can help bioethicists better appreciate how medicine can intensify, pathologize, and exploit anxieties about illness and death, thus adding to the challenges of living well in the face of mortality and morbidity.

    One to Many communications are expected to be among the killer applications for the currently discussed 5G standard. The usage of coding mechanisms is impacting broadcasting standard quality, as coding is involved at several levels of the stack, and more specifically at the application layer where Rateless, LDPC, Reed Slomon codes and network coding schemes have been extensively studied, optimized and standardized in the past. Beyond reusing, extending or adapting existing application layer packet coding mechanisms based on previous schemes and designed for the foregoing LTE or other broadcasting standards; our purpose is to investigate the use of Generalized Reed Muller codes and the value of their locality property in their progressive decoding for Broadcast/Multicast communication schemes with real time video delivery. Our results are meant to bring insight into the use of locally decodable codes in Broadcasting. © 2016 IEEE.

  19. Jane Eyre : un roman innovant pour les critiques victoriens Jane Eyre: an Innovating Novel according to the Victorian Critics

    Full Text Available After the failure to publish her first novel The Professor Charlotte Brontë wrote her second work of fiction Jane Eyre in a conscious effort to satisfy the critics’ expectations, combining the more traditional elements of novel-writing with more innovating ones suggested by her own imagination. An examination of the reviews which appeared in the months following the publication of Jane Eyre reveals Charlotte Brontë’s strategy: her choice of an unconventional relationship between the poor, plain governess and her wealthy, passionate master, the exploration of her heroine’s interior life combined with the realistic descriptions of her characters’ physical and social environment. This combination ensured the success of the novel which was overwhelmingly praised for its innovative elements even if the more conservative critics disapproved of such novelties.

  20. Idealized digital models for conical reed instruments, with focus on the internal pressure waveform.

    Two models for the generation of self-oscillations of reed conical woodwinds are presented. The models use the fewest parameters (of either the resonator or the exciter), whose influence can be quickly explored. The formulation extends iterated maps obtained for lossless cylindrical pipes without reed dynamics. It uses spherical wave variables in idealized resonators, with one parameter more than for cylinders: the missing length of the cone. The mouthpiece volume equals that of the missing part of the cone, and is implemented as either a cylindrical pipe (first model) or a lumped element (second model). Only the first model adds a length parameter for the mouthpiece and leads to the solving of an implicit equation. For the second model, any shape of nonlinear characteristic can be directly considered. The complex characteristic impedance for spherical waves requires sampling times smaller than a round trip in the resonator. The convergence of the two models is shown when the length of the cylindrical mouthpiece tends to zero. The waveform is in semi-quantitative agreement with experiment. It is concluded that the oscillations of the positive episode of the mouthpiece pressure are related to the length of the missing part, not to the reed dynamics.

    Full Text Available Aiming to improve the sustainability of biogas supply chains, the research for alternative feedstocks is a key issue and giant reed (Arundo donax L. is a promising no-food crop to be used in anaerobic digestion. In fact, giant reed is a perennial species characterised by low nutrient requirements and is able to provide promising biogas yields. Its suitability for anaerobic digestion is influenced by harvest time, since plant characteristics vary noticeably along the season. Moreover, ensiling is a storage technique that can assure a good preservation of the biomass over time, but also influence the methane yields. Therefore, the aim of this study was to assess the suitability for biogas production of giant reed silage, according to different cutting regimes, and to evaluate the efficiency in saving land and nitrogen for fuelling biogas plants, in comparison with maize and two sorghum varieties. Methane yields per hectare (Nm3 CH4 ha–1 were determined by multiplying the biochemical methane potential of each substrate by the aboveground biomass of the corresponding crop. The land use coefficient (LU, namely the land needed to fuel one kW power (ha kWe–1, was calculated from the estimated methane yields per hectare. Finally, nitrogen utilisation efficiency (NUtE, which is the ratio between the estimated methane yield and the nitrogen uptake per hectare (Nm3 CH4 kgN–1, was determined for each crop species and according to the harvest time and frequency of giant reed. Overall, a good suitability for ensiling was observed in giant reed. When harvested in September, the crop yielded about 9900 Nm3 CH4 ha–1, while in double harvest systems biomethane was about 12,000 Nm3 CH4 ha–1, +35% and +70% than maize and sorghum respectively. Moreover, giant reed under double harvest management was the most land-conservative option, as LU was about 0.22 ha kWe–1, while in annual crops it was about 0.35 ha kWe–1. The higher NUtE was observed in single

    The feasibility of RCG for commercial utilization depends primarily on its applicability for pulp production and its use in energy production will be based on the residue that will be available after extracting the pulp fraction of the RCG. Roughly 20 ..30% of the material will be available for energy production purposes. However, the percentage may be higher/lower depending on the quality standards of the pulp fiber material. The harvesting period has a significant effect on the fuel characteristics of RCG. For instance the contents of N, S, Cl, K are clearly lower if the RCG is harvested in the spring (delayed) instead of summer/autumn. These elements affect significantly overall emission formation and ash behaviour and its melting temperature. The combustion related research in this project has been focused on the spring-harvested RCG. The project aims to evaluate the feasibility of delayed harvested RCG for energy production. In order to reach this goal, the following combustion methods will be tested and studied: combustion of pelletized RCG; gasification; combustion of pulverized RCG. In addition, pelletizing, reactivity and NO conversion of pulverized RCG will be studied. The research described here is a part of `Reed Canary Grass` project (in AIR programme). The contractors of the project are Swedish University of Agricultural Sciences (coordinator), United Milling Systems from Denmark, Jaakko Poeyry Oy and VTT Energy. In addition, there are partners from several countries participating in the project. The project has been divided in five tasks, VTT Energy being responsible for combustion related task `Upgraded fuel` that includes the research topics discussed in this paper

    An important issue for electricity system operators is the estimation of renewables' capacity contributions to reliably meeting system demand, or their capacity value. While the capacity value of thermal generation can be estimated easily, assessment of wind and solar requires a more nuanced approach due to the resource variability. Reliability-based methods, particularly assessment of the Effective Load-Carrying Capacity, are considered to be the most robust and widely-accepted techniques for addressing this resource variability. This report compares estimates of solar PV capacity value by the Regional Energy Deployment System (ReEDS) capacity expansion model against two sources. The first comparison is against values published by utilities or other entities for known electrical systems at existing solar penetration levels. The second comparison is against a time-series ELCC simulation tool for high renewable penetration scenarios in the Western Interconnection. Results from the ReEDS model are found to compare well with both comparisons, despite being resolved at a super-hourly temporal resolution. Two results are relevant for other capacity-based models that use a super-hourly resolution to model solar capacity value. First, solar capacity value should not be parameterized as a static value, but must decay with increasing penetration. This is because -- for an afternoon-peaking system -- as solar penetration increases, the system's peak net load shifts to later in the day -- when solar output is lower. Second, long-term planning models should determine system adequacy requirements in each time period in order to approximate LOLP calculations. Within the ReEDS model we resolve these issues by using a capacity value estimate that varies by time-slice. Within each time period the net load and shadow price on ReEDS's planning reserve constraint signals the relative importance of additional firm capacity.

    2009-05-01

    Full Text Available One outcome of Jane Austen’s popularity with present-day readers is their creation of books derived from and inspired by her own. This article examines a recent contribution to this increasingly crowded field: Lori Smith’s 2007 'A Walk with Jane Austen: A Journey into Adventure, Love & Faith', which depicts a thirtysomething American woman’s travel to England in the hopes of better understanding both Austen and herself. I consider this memoir in relation to other works created by Austen fans, including those who, like Smith, aim primarily at a Christian readership; I address as well this book’s significance as an account of literary pilgrimage and of personally transformative reading.

  16. The Distribution and Frequency of the Terms "Pride" and "Prejudice" in Jane Austen's Pride and Prejudice

    2009-03-01

    Full Text Available In this article we examine the title terms of Jane Austen's Pride and Prejudice (1813 with particular attention to their distribution and frequency in the text. Our method is to connect the statistical material gathered on frequency and distribution to a narratological analysis of the terms, with special emphasis on whether they occur within the focalization of the external narrator, or that of character-focalizers. In order to approach this task, we have availed ourselves of the narratological theories of Mieke Bal. We conclude that there is a differentiation among types of focalization in the novel that enhances the thematic structure of match-making. Although Jane Austen wrote and published her major works two centuries ago, they continue to fascinate literary scholars and general readers alike.

  17. ‘Gaze’ and ‘Visuality’ in Jane Austen’s Pride and Prejudice

    Directory of Open Access Journals (Sweden)

    Zolfagharkhani M.

    2012-01-01

    Full Text Available For many readers, there is no connection between Jane Austen’s novels and the sexualized body. Sexuality in Austen’s novels is never explicit; nonetheless, it permeates every look, gesture, and letter that passes between her lovers. This article aims to reveal the concept of ‘gaze’, especially female gaze, in Jane Austen’s Pride and Prejudice. According to feminist critics it is psychologically inevitable that women are the sexual objects of men; therefore, they have effectively refused to acknowledge the possibility that a female gaze could exist. Arguably, as it is indicated throughout this article, women are not necessarily rendered mute and inert by the male gaze; in fact, they actively shape and respond to male desire and their gaze encompasses as much authority and power as the male gaze.

    2015-01-01

    References to neurologic disorders are frequently found in fictional literature and may precede description in the medical literature. Our aim was to compare Charlotte Brontë's depiction of Bertha Mason in Jane Eyre to the tenets set forth in George Huntington's original essay "On chorea" with the hypothesis that Mason was displaying features of Huntington disease. Charlotte Brontë's 1847 Victorian novel Jane Eyre features the character Bertha Mason, who is portrayed with a progressive psychiatric illness, violent movements, and possible cognitive decline. Similar to Huntington's tenets, Mason has a disorder with a strong family history suggestive of autosomal dominant inheritance with onset in adulthood, and culminating in suicide. Brontë's character had features of Huntington disease as originally described by Huntington. Brontë's keen characterization may have increased awareness of treatment of neuropsychiatric patients in the Victorian era.

    Jane Austen's purpose in Northanger Abbey, both in her aesthetic principles and moral intents, is to explore the human experience in its fullest sense. How do people perceive and understand themselves and each other? What are they like and how can they learn and grow? If moral problems are a question of thought rather than of action, as a consequence to ask what characters are like is also to ask what an author's conception of them should be.

  6. Captation spéculaire et mise en abyme dans le film Jane Eyre de Franco Zeffirelli Specular Captation and Metafictional Devices in Zeffirelli’s Jane Eyre

    Directory of Open Access Journals (Sweden)

    Isabelle Van Peteghem-Tréard

    2009-07-01

    Full Text Available This article presents Franco Zeffirelli’s baroque use of mirrors to evoke the specular alienation of Jane Eyre who is both the heroine and the story-teller in the movie and in the original text. The mirror image—or, condensed into a single word, the “mirage”—is not only whole and non-human as opposed to fragmented, turbulent and human, it is an “exteriority,” an outside that is also inside. The ego experiences a perpetual rift that is modeled on the subject’s dual relations with its specular counterpart, the other woman. The mirror stage presents through dramatic exemplification a certain level of rupture between inwardly lived and external realities. The director thus emphasizes the question of representation and its various metafictional modes as Jane Eyre—the movie— can be seen as a portrait of the artist. Drawing can be regarded as the cinematic equivalent of narration in Charlotte Brontë’s work and also as empowerment for the female subject who ultimately becomes a creator.

  8. Contribution to harmonic balance calculations of self-sustained periodic oscillations with focus on single-reed instruments.

    The harmonic balance method (HBM) was originally developed for finding periodic solutions of electronical and mechanical systems under a periodic force, but has been adapted to self-sustained musical instruments. Unlike time-domain methods, this frequency-domain method does not capture transients and so is not adapted for sound synthesis. However, its independence of time makes it very useful for studying any periodic solution, whether stable or unstable, without care of particular initial conditions in time. A computer program for solving general problems involving nonlinearly coupled exciter and resonator, HARMBAL, has been developed based on the HBM. The method as well as convergence improvements and continuation facilities are thoroughly presented and discussed in the present paper. Applications of the method are demonstrated, especially on problems with severe difficulties of convergence: the Helmholtz motion (square signals) of single-reed instruments when no losses are taken into account, the reed being modeled as a simple spring.

    The regolith-lake development model (RLDM) describes the development of shallow bays to lakes and the infilling of lakes in the Forsmark area during an interglacial. The sensitivity analysis has shown the need for an update of the infill procedure in the RLDM. Data from the mapping of reed in shallow bays in the Forsmark area will be used to improve the infill procedure of an updated RLDM. The field work was performed in August 26-31, 2010. The mapping of reed was done in 124 points. In these points, coordinates and water depth were mapped using an echo sounder and a DGPS. Quaternary deposits and the thickness of soft sediments were mapped using an earth probe. Measurement points were delivered in ESRI shape format with coordinates in RT90 2.5 gon W and altitudes in the RHB70 system for storage in SKB's GIS data base

    International audience; This paper considers a "striking outwards" reed coupled to a resonator. This expression, due to Helmholtz, is not discussed here : it corresponds to the most common model of a lip-type valve, when the valve is assumed to be a one degree of freedom oscillator. The presented work is an extension of the works done by Wilson and Beavers (1974), Tarnopolsky (2000). The range of the playing frequencies is investigated.

    It has now been 100 years since Dorothy Reed, at the age of 28, wrote her paper on Hodgkin's disease. Her biography reveals the difficult lives of women entering the hitherto male-dominated field of medicine, let alone medical research. Her historic paper on Hodgkin's disease is remarkable for its brilliant observations and concise scientific reasoning. Nevertheless, she was told that as a woman she could not hope for a career as an academic pathologist. After marriage to Charles Elwood Mendenhall, Professor of Physics at the University of Wisconsin and after giving birth to four children, the second part of her career began. Motivated by the loss of her firstborn, she began a study of infant mortality, an interest that lasted throughout her career. In 1926, Mendenhall undertook a survey comparing infant and maternal mortality rates in Denmark and the United States. This influential study concluded that American mortality rates were higher because of unnecessary interference in the natural process of childbirth and recommended the education of midwives follow the Danish model. In 1937, her efforts were rewarded when Madison, WI received recognition for having the lowest infant mortality of any city in the United States. Reading Reed's paper on Hodgkin's disease, we see that her observations go far beyond a description of a specific cell. Her presentation of macroscopic and microscopic features is remarkable for the distinction between 'young' and 'old' growths: Reed saw Hodgkin's disease as a process, rather than the spreading of a cancer. She was the first to note that those most commonly affected are boys or young adults, especially those whose general health before the disease had been excellent. She was also the first to note anergy to tuberculin. Dorothy Reed defined Hodgkin's disease in relation to tuberculosis, described its pathologic features, and offered comments on its pathogenesis, epidemiology, and immunology that still deserve to be discussed

    In"Jane Eyre", Charlotte Bronte's masterpiece the heroine, Jane Eyre has fully reflected her self-esteem, equality, and pure personality, which are also reflected in her concept of love vividly. However, Thomas Hardy's Tess is poor and kind, but she does not have a complete love like Jane Eyre, and she is described by his criticism of the old moral character with good vir-tues in the traditional sense. She is a new image of modern feminism who suffered from the old moral sense and gradually has re-volt consciousness. From the feminism viewpoint, this paper attempts to analysis the causes of their different fate from different points and reveal the impact of social background on their fates.

    We construct balanced and sparsest generator matrices for cyclic Reed-Solomon codes with any length n and dimension k. By sparsest, we mean that each row has the least possible number of nonzeros, while balanced means that the number of nonzeros in any two columns differs by at most one. Codes allowing such encoding schemes are useful in distributed settings where computational load-balancing is critical. The problem was first studied by Dau et al. who showed, using probabilistic arguments, that there always exists an MDS code over a sufficiently large field such that its generator matrix is both sparsest and balanced. Motivated by the need for an explicit construction with efficient decoding, the authors of the current paper showed that the generator matrix of a cyclic Reed-Solomon code of length n and dimension k can always be transformed to one that is both sparsest and balanced, when n and k are such that k/n (n-k+1) is an integer. In this paper, we lift this condition and construct balanced and sparsest generator matrices for cyclic Reed-Solomon codes for any set of parameters.

    The giant reed (Arundo donax L.) is amongst the one hundred worst invasive alien species of the world, and it is responsible for biodiversity loss and failure of ecosystem functions in riparian habitats. In this work, field spectroradiometry was used to assess the spectral separability of the giant reed from the adjacent vegetation and from the common reed, a native similar species. The study was conducted at different phenological periods and also for the giant reed stands regenerated after mechanical cutting (giant reed_RAC). A hierarchical procedure using Kruskal-Wallis test followed by Classification and Regression Trees (CART) was used to select the minimum number of optimal bands that discriminate the giant reed from the adjacent vegetation. A new approach was used to identify sets of wavelengths - wavezones - that maximize the spectral separability beyond the minimum number of optimal bands. Jeffries Matusita and Bhattacharya distance were used to evaluate the spectral separability using the minimum optimal bands and in three simulated satellite images, namely Landsat, IKONOS and SPOT. Giant reed was spectrally separable from the adjacent vegetation, both at the vegetative and the senescent period, exception made to the common reed at the vegetative period. The red edge region was repeatedly selected, although the visible region was also important to separate the giant reed from the herbaceous vegetation and the mid infrared region to the discrimination from the woody vegetation. The highest separability was obtained for the giant reed_RAC stands, due to its highly homogeneous, dense and dark-green stands. Results are discussed by relating the phenological, morphological and structural features of the giant reed stands and the adjacent vegetation with their optical traits. Weaknesses and strengths of the giant reed spectral discrimination are highlighted and implications of imagery selection for mapping purposes are argued based on present results.

    Full Text Available The low carbon/nitrogen (C/N ratio and high nitrate content characteristics of agricultural runoff restricted the nitrogen removal in constructed wetlands (CWs. To resolve such problems, the economically- and easily-obtained Phragmites Australis (reeds litters were applied and packed in the surface layer of a surface flow CW as external carbon sources. The results demonstrated that the introduction of the reeds straw increased the C concentration as a result of their decomposition during the CW operation, which will help the denitrification in the ensuing operation of an entire 148 days. The total nitrogen (TN and Chemical Oxygen Demand (COD ( in the effluent reached the peak level of 63.2 mg/L and 83 mg/L at the fourth and the second day, respectively. Subsequently, the pollutants in the CW that were filled with straw decreased rapidly and achieved a stable removal after 13 days of operation. Moreover, the present study showed that the N removal efficiency increased with the increase of the hydraulic retention time (HRT. Under the HRT of four days, the CW presented 74.1 ± 6%, 87.4 ± 6% and 56.0 ± 6% removal for TN, NO3-, and TP, respectively.

    Full Text Available This article examines Jane Austen's Mansfield Park in the context of the complex relationship between imaginative literature and the experience of empire. Specifically, it argues that the way Austen's novel plays with the imperial experience is more ambivalent than many critics have indicated. It suggests that underlying the imaginative conceptualization of the relations between metropole and colony are certain evasions and contradictions in which the novel consciously abounds. A close reading of the novel demonstrates how issues related to metropole and colony may be articulated within the literary mainstream, and why such narrative articulation is important.

    The article is devoted to the development of a modern highly reliable element base of devices for security and fire alarm systems, in particular, to the improvement of the quality of contact cores (reed and membrane) of reed sensors. Modeling of elastic sensitive elements uses quadrangular elements of plates and shells, considered in the system of curvilinear orthogonal coordinates. The developed mathematical models and the formed finite element library are designed for systems of automated design of reed switch detectors to create competitive devices alarms. The finite element library is used for the automated system production of reed switch detectors both in series production and in the implementation of individual orders.

  8. Optimizing Frozen Sample Preparation for Laser Microdissection: Assessment of CryoJane Tape-Transfer System®.

    Directory of Open Access Journals (Sweden)

    Yelena G Golubeva

    Full Text Available Laser microdissection is an invaluable tool in medical research that facilitates collecting specific cell populations for molecular analysis. Diversity of research targets (e.g., cancerous and precancerous lesions in clinical and animal research, cell pellets, rodent embryos, etc. and varied scientific objectives, however, present challenges toward establishing standard laser microdissection protocols. Sample preparation is crucial for quality RNA, DNA and protein retrieval, where it often determines the feasibility of a laser microdissection project. The majority of microdissection studies in clinical and animal model research are conducted on frozen tissues containing native nucleic acids, unmodified by fixation. However, the variable morphological quality of frozen sections from tissues containing fat, collagen or delicate cell structures can limit or prevent successful harvest of the desired cell population via laser dissection. The CryoJane Tape-Transfer System®, a commercial device that improves cryosectioning outcomes on glass slides has been reported superior for slide preparation and isolation of high quality osteocyte RNA (frozen bone during laser dissection. Considering the reported advantages of CryoJane for laser dissection on glass slides, we asked whether the system could also work with the plastic membrane slides used by UV laser based microdissection instruments, as these are better suited for collection of larger target areas. In an attempt to optimize laser microdissection slide preparation for tissues of different RNA stability and cryosectioning difficulty, we evaluated the CryoJane system for use with both glass (laser capture microdissection and membrane (laser cutting microdissection slides. We have established a sample preparation protocol for glass and membrane slides including manual coating of membrane slides with CryoJane solutions, cryosectioning, slide staining and dissection procedure, lysis and RNA extraction

    2015-07-01

    Full Text Available Background: References to neurologic disorders are frequently found in fictional literature and may precede description in the medical literature. Aim: Our aim was to compare Charlotte Brontë’s depiction of Bertha Mason in Jane Eyre to the tenets set forth in George Huntington’s original essay “On chorea” with the hypothesis that Mason was displaying features of Huntington disease. Results: Charlotte Brontë’s 1847 Victorian novel Jane Eyre features the character Bertha Mason, who is portrayed with a progressive psychiatric illness, violent movements, and possible cognitive decline. Similar to Huntington’s tenets, Mason has a disorder with a strong family history suggestive of autosomal dominant inheritance with onset in adulthood, and culminating in suicide. Conclusion: Brontë’s character had features of Huntington disease as originally described by Huntington. Brontë’s keen characterization may have increased awareness of treatment of neuropsychiatric patients in the Victorian era.

  10. A Bold New Timeless Classic: Fukunaga’s Partial Reading of Jane Eyre

    Directory of Open Access Journals (Sweden)

    John Engle

    2012-07-01

    Full Text Available With its first person narrator, radical tonal changes, and wild blend of genres (autobiography, romance, Gothic melodrama, Christian exemplum, etc., Brontë’s Jane Eyre is a case study in the difficulties of cinematic adaptation, as the filmmaker attempts to balance "fidelity" with contemporary relevance and entertainment value. This article examines Cary Fukunaga’s 2011 version, and in particular certain orientations animating his necessarily "partial" reading of the novel. Chief among these is the decision to begin the film when Jane leaves Thornfield; recounting much of the story in discontinuous flashback, the film manages simultaneously to admit Jane’s narrative voice while eliminating its potentially distracting nature. Fukunaga’s other choices include the toning down of the novel’s lurid Gothic quality, its overt romanticism, and—today an overly familiar romantic comedy stereotype—the teasing interplay between the two protagonists. Communicating in a compact language of visual symbol, he also uses the original’s "religious plot" as a tool for modern character analysis.

    Wetland biomass is essential for monitoring the stability and productivity of wetland ecosystems. Conventional field methods to measure or estimate wetland biomass are accurate and reliable, but expensive, time consuming and labor intensive. This research explored the potential for estimating wetland reed biomass using a combination of airborne discrete-return Light Detection and Ranging (LiDAR) and hyperspectral data. To derive the optimal predictor variables of reed biomass, a range of LiDAR and hyperspectral metrics at different spatial scales were regressed against the field-observed biomasses. The results showed that the LiDAR-derived H_p99 (99th percentile of the LiDAR height) and hyperspectral-calculated modified soil-adjusted vegetation index (MSAVI) were the best metrics for estimating reed biomass using the single regression model. Although the LiDAR data yielded a higher estimation accuracy compared to the hyperspectral data, the combination of LiDAR and hyperspectral data produced a more accurate prediction model for reed biomass (R2 = 0.648, RMSE = 167.546 g/m2, RMSEr = 20.71%) than LiDAR data alone. Thus, combining LiDAR data with hyperspectral data has a great potential for improving the accuracy of aboveground biomass estimation.

    Directory of Open Access Journals (Sweden)

    Eileen Williams-Wanquet

    2009-10-01

    Full Text Available Although none of Brookner’s twenty-three novels to date actually re-write Jane Eyre as hypotext, Brontë’s novel is part of the pervasive intertextuality of Brookner’s text, addressed here as a monolithic fiction. This omnipresent intertextuality, which is the key to understanding the whole œuvre, serves to define the moral codes followed by the heroine and to make a philosophical metacommentary on contemporary culture. Brookner’s characters read and comment on Jane Eyre, the heroine takes Jane as a role model of virtue and the masculine characters are divided into those who resemble Mr Rochester and those who belong to the same category as St John Rivers. But Brookner’s text is a re-vision of Brontë’s novel, as of other novels set in the tradition of the classic realist text and of romance, which have Cartesian rationalism and Christianity as philosophical underpinnings. Brookner reverses the poetic justice of Jane Eyre, which is re-contextualised to fit a new moral landscape in which God is dead as ultimate justification for virtuous conduct. Whereas Jane Eyre can ultimately be read as a “Victorian romance” which preaches reason in the name of social order, by replacing the traditional happy ending by an unhappy ending in which virtue is punished and by foregrounding the disastrous effects of suppressing passion in the name of reason or self in the name of the other, Brookner announces the end of a philosophical humanistic tradition in which the subject / object or self / other opposition gives rise to a host of binary oppositions, the notion of centre validating the dominance of one of the terms of the hierarchy.

    This paper reports that declines characterize the 1992 rig census-in the number of available drilling rigs, in the number of active rigs, in rig utilization rate, in the number of rig owners and in industry optimism. The number of rotary rigs available for U.S. drilling fell by 255 units (11.3%) during the past 12 months, an attrition rate almost four times greater than in 1991. But despite the high attrition, only 59.7% of remaining rigs were working during the time the census was taken. Results of the 1992 census bring emphasis to an industry trend that became apparent in early 1991. The major oil companies, and many independents, continued their exodus form the U.S., and the remaining independents, which were hurt by low natural gas prices and unfavorable tax treatment of intangible drilling costs, were not able to pick u the drilling slack. Consequently, the past year has been disastrous for many U.S. drilling contractors, and the outlook for this industry segment remains bleak

  20. Reed-Solomon Codes and the Deep Hole Problem

    Science.gov (United States)

    Keti, Matt

    In many types of modern communication, a message is transmitted over a noisy medium. When this is done, there is a chance that the message will be corrupted. An error-correcting code adds redundant information to the message which allows the receiver to detect and correct errors accrued during the transmission. We will study the famous Reed-Solomon code (found in QR codes, compact discs, deep space probes,ldots) and investigate the limits of its error-correcting capacity. It can be shown that understanding this is related to understanding the "deep hole" problem, which is a question of determining when a received message has, in a sense, incurred the worst possible corruption. We partially resolve this in its traditional context, when the code is based on the finite field F q or Fq*, as well as new contexts, when it is based on a subgroup of F q* or the image of a Dickson polynomial. This is a new and important problem that could give insight on the true error-correcting potential of the Reed-Solomon code.

    A problem in designing semiconductor memories is to provide some measure of error control without requiring excessive coding overhead or decoding time. For example, some 256K-bit dynamic random access memories are organized as 32K x 8 bit-bytes. Byte-oriented codes such as Reed Solomon (RS) codes provide efficient low overhead error control for such memories. However, the standard iterative algorithm for decoding RS codes is too slow for these applications. Some special high speed decoding techniques for extended single and double error correcting RS codes. These techniques are designed to find the error locations and the error values directly from the syndrome without having to form the error locator polynomial and solve for its roots.

    In this study, hydrodynamic cavitation (HC) was employed as a physical means to improve alkaline pretreatment of reed. The HC-assisted alkaline pretreatment was undertaken to evaluate the influence of NaOH concentration (1-5%), solid-to-liquid ratio (5-15%), and reaction time (20-60 min) on glucose yield. The optimal condition was found to be 3.0% NaOH at solid-to-liquid (S/L) ratio of 11.8% for 41.1 min, which resulted in the maximum glucose yield of 326.5 g/kg biomass. Furthermore, simultaneous saccharification and fermentation (SSF) was conducted to assess the ethanol production. An ethanol concentration of 25.9 g/L and ethanol yield of 90% were achieved using batch SSF. These results clearly demonstrated HC system can be indeed a promising pretreatment tool for lignocellulosic bioethanol production. Copyright © 2015 Elsevier Ltd. All rights reserved.

A multiphase retrospective analysis was conducted to determine the use of the "Search & Learn" medical information and the relative number of prescription refills and appointments conducted via the WWW compared with conventional methods. From January 2001 to May 2002, there were 34,741 refills and 819 appointments made over the Internet compared with 2,275,112 refills and approximately 500,000 appointments made conventionally. WWW activity accounted for 1.52% of refills and 0.16% of appointments. There was a steady increase in this percentage over the time of the analysis. In April of 2002, the monthly average of online refills had risen to 4.57% and online appointments were at 0.27%. Online refills were projected to account for 10% of all prescriptions in 2 years. The "Search & Learn" medical information portion of our web site received 147,429 unique visits during this same time frame, which was an average of 326 visitors per day. WWW-based methods of conducting essential medical tasks accounted for a small but rapidly increasing percentage of total activity at Walter Reed Army Medical Center. Subsequent phases of analysis will assess demographic and geographic factors and aid in the design of future systems to increase use of the Internet-based systems.

  4. Behavioural Susceptibility Theory: Professor Jane Wardle and the Role of Appetite in Genetic Risk of Obesity.

    There is considerable variability in human body weight, despite the ubiquity of the 'obesogenic' environment. Human body weight has a strong genetic basis and it has been hypothesised that genetic susceptibility to the environment explains variation in human body weight, with differences in appetite being implicated as the mediating mechanism; so-called 'behavioural susceptibility theory' (BST), first described by Professor Jane Wardle. This review summarises the evidence for the role of appetite as a mediator of genetic risk of obesity. Variation in appetitive traits is observable from infancy, drives early weight gain and is highly heritable in infancy and childhood. Obesity-related common genetic variants identified through genome-wide association studies show associations with appetitive traits, and appetite mediates part of the observed association between genetic risk and adiposity. Obesity results from an interaction between genetic susceptibility to overeating and exposure to an 'obesogenic' food environment.

    2014-01-01

    Sometimes the opinion regarding the cause of death in “John Doe or Jane Doe” i.e. on unknown dead bodies is a test of ability of the forensic expert and on many occasions it yields little or no results. Here the identification of the body as such poses problems; rest aside the opinion regarding the cause/ manner of death. The present 5yr study was undertaken in the Department of Forensic Medicine & Toxicology, Government Medical College & Hospital, Chandigarh to find the patterns of cause of death in unknown dead bodies, as very little literature is available with regard to John Doe or Jane Doe cases as a group, in India. Unidentified bodies comprised 4 % of the total 3165 cases brought for post-mortem examination to the department. Maximum cases belonged to the age group 41 - 50 years, 30 %. Majority of the opinions regarding the cause of death were given as “no definite opinion” (31%), followed by “cranio-cerebral damage” (30 %) and coronary insufficiency/ Cardiac disease/ aortic aneurysm rupture, (8.9%). Following measures should be undertaken to increase the chances of getting these unknown bodies identified and thereby increasing the chances of arriving at a definite cause of death: drafting of additional legislation for the management of unidentified dead bodies along with streamlining of work on the part of police, use of active investigation and modern investigative techniques, fixing the accountability of the police. Internet based sites of the police like ZIPNET (Zonal Integrated Police Networking) in Northern India, should also be used. PMID:25302219

    Full Text Available Reed is a widespread-growing, inexpensive, and readily available lignocellulosic material source in northeast China. The objective of this study is to evaluate the liquid hot water (LHW pretreatment efficiency of reed based on the enzymatic digestibility and ethanol fermentability of water-insoluble solids (WISs from reed after the LHW pretreatment. Several variables in the LHW pretreatment and enzymatic hydrolysis process were optimized. The conversion of glucan to glucose and glucose concentrations are considered as response variables in different conditions. The optimum conditions for the LHW pretreatment of reed area temperature of 180°C for 20min and a solid-to-liquid ratio of 1 : 10. These optimum conditions for the LHW pretreatment of reed resulted in a cellulose conversion rate of 82.59% in the subsequent enzymatic hydrolysis at 50°C for 72 h with a cellulase loading of 30 filter paper unit per gram of oven-dried WIS. Increasing the pretreatment temperature resulted in a higher enzymatic digestibility of the WIS from reed. Separate hydrolysis and fermentation of WIS showed that the conversion of glucan to ethanol reached 99.5% of the theoretical yield. The LHW pretreatment of reed is a suitable method to acquire a high recovery of fermentable sugars and high ethanol conversion yield.

    In this study, reed planting tests were carried out at the Biyo-center, an experiment station on the Lake Biwa shore, in order to evaluate the feasibility of a planting method with porous concrete (PoC method). Reed planting tests with coconut-fiber mats (mat method), which were generally used around Lake Biwa, were simultaneously carried out to compare with the PoC method. The reeds planted by the PoC method grew better than the ones planted by the mat method, and the number of reeds which were washed away by waves was smaller than that planted by the mat method. The result of the observation of reeds planted in the PoC showed plant maturation, and reeds could ta ke root into the PoC without interference with the voids of the PoC. As a result, it was shown that the reed planting tests with the PoC method was simple and effective, so it would become in harmony with the environment around Lake Biwa.

    We show that quantum Reed-Solomon codes constructed from classical Reed-Solomon codes can approach the capacity on the quantum erasure channel of d -level systems for large dimension d . We study the performance of one-way quantum repeaters with these codes and obtain a significant improvement in key generation rate compared to previously investigated encoding schemes with quantum parity codes and quantum polynomial codes. We also compare the three generations of quantum repeaters using quantum Reed-Solomon codes and identify parameter regimes where each generation performs the best.

  16. Space communication system for compressed data with a concatenated Reed-Solomon-Viterbi coding channel

    1976-01-01

    A space communication system incorporating a concatenated Reed Solomon Viterbi coding channel is discussed for transmitting compressed and uncompressed data from a spacecraft to a data processing center on Earth. Imaging (and other) data are first compressed into source blocks which are then coded by a Reed Solomon coder and interleaver, followed by a convolutional encoder. The received data is first decoded by a Viterbi decoder, followed by a Reed Solomon decoder and deinterleaver. The output of the latter is then decompressed, based on the compression criteria used in compressing the data in the spacecraft. The decompressed data is processed to reconstruct an approximation of the original data-producing condition or images.

  17. Hydrothermal Conversion of Giant Reed to Furfural and Levulinic Acid: Optimization of the Process under Microwave Irradiation and Investigation of Distinctive Agronomic Parameters

    Full Text Available The hydrothermal conversion of giant reed (Arundo donax L. to furfural (FA and levulinic acid (LA was investigated in the presence of dilute hydrochloric acid. FA and LA yields were improved by univariate optimization of the main reaction parameters: concentration of the acid catalyst, solid/liquid ratio of the reaction mixture, hydrolysis temperature, and reaction time. The catalytic performances were investigated adopting the efficient microwave (MW irradiation, allowing significant energy and time savings. The best FA and LA yields were further confirmed using a traditionally heated autoclave reactor, giving very high results, when compared with the literature. Hydrolysis temperature and time were the main reaction variables to be carefully optimized: FA formation needed milder reaction conditions, while LA more severe ones. The effect of the crop management (e.g., harvest time on FA/LA production was discussed, revealing that harvest time was not a discriminating parameter for the further optimization of both FA and LA production, due to the very high productivity of the giant reed throughout the year. The promising results demonstrate that giant reed represents a very interesting candidate for a very high contemporary production of FA and LA of up to about 70% and 90% of the theoretical yields, respectively.

  18. The Effects of Supplementary Food on the Breeding Performance of Eurasian Reed Warblers Acrocephalus scirpaceus; Implications for Climate Change Impacts.

    Directory of Open Access Journals (Sweden)

    James O Vafidis

    Full Text Available Understanding the mechanisms by which climate variation can drive population changes requires information linking climate, local conditions, trophic resources, behaviour and demography. Climate change alters the seasonal pattern of emergence and abundance of invertebrate populations, which may have important consequences for the breeding performance and population change of insectivorous birds. In this study, we examine the role of food availability in driving behavioural changes in an insectivorous migratory songbird; the Eurasian reed warbler Acrocephalus scirpaceus. We use a feeding experiment to examine the effect of increased food supply on different components of breeding behaviour and first-brood productivity, over three breeding seasons (2012-2014. Reed warblers respond to food-supplementation by advancing their laying date by up to 5.6 days. Incubation periods are shorter in supplemented groups during the warmest mean spring temperatures. Nestling growth rates are increased in nests provisioned by supplemented parents. In addition, nest predation is reduced, possibly because supplemented adults spend more time at the nest and faster nestling growth reduces the period of vulnerability of eggs and nestlings to predators (and brood parasites. The net effect of these changes is to advance the fledging completion date and to increase the overall productivity of the first brood for supplemented birds. European populations of reed warblers are currently increasing; our results suggest that advancing spring phenology, leading to increased food availability early in the breeding season, could account for this change by facilitating higher productivity. Furthermore, the earlier brood completion potentially allows multiple breeding attempts. This study identifies the likely trophic and behavioural mechanisms by which climate-driven changes in invertebrate phenology and abundance may lead to changes in breeding phenology, nest survival and net

    The reliability and accuracy of the information on control rod position are very important to the reactor safety and the design of the core protection system. A survey on the RSPT(Reed Switch Position Transmitter) type control rod position indication system and its actual implementation in the exiting nuclear power plants in Korea was performed first. The control rod position indicator having the high performance for SMART was developed on the basis of RSPT technology identified through the survey. The arrangement of permanent magnet and reed switches is the most important procedure in the design of control rod position indication. In this study, the characteristics of permanent magnet and reed switches are introduced and the calculation method for arrangement of permanent magnet and reed switch is presented

Son historias paralelas de abandono y búsquedas fallidas que convergen en un punto: Edward Rochester. Se sugiere que el final feliz de Jane y el final trágico de Antoinette están determinados por la imposibilidad del etos victoriano, encarnado en Rochester, de aceptar el caos: el desorden que representa Antoinette —desorden de la alteridad— debe ser sometido.

These parallel stories of abandonment and failed searches converge in one point: Edward Rochester. It is suggested that Jane’s happy ending and Antoinette’s tragic ending are both determined by the impossibility of the Victorian ethos, personified in Rochester, to accept chaos: the disorder represented by Antoinette —disorder of alterity— must be tamed. Repression, then, appears as the sole possibility of existence.

    A new DNA synthesis by the Sternberg-Reed cells in Hodgkin disease was studied using tritiated thymidine and autoradiography. The results show that after incubation pulses of 30 and 60 minutes, cells with lobulated nucleus, binucleated and trinucleated cells identifiable to the diagnostic Sternberg-Reed cells could undergo a new DNA synthesis. This points to a more dynamic interpretation of this type of cell.

    Monotypic stands of common reed and the reed-gall-associated insect assemblages are distributed worldwide. However, fungi associated with these assemblages have not been characterized in detail. Here we examined 5200 individuals (12 species) of immature aculeate hymenopterans or their parasitoids collected at 34 sampling sites in Central Europe. We noticed fungal outgrowth on exoskeletons of 83 (1.60%) larvae and pupae. The most common host was eudominant Pemphredon fabricii. However, the less abundant aculeate hymenopteran reed gall inquilines were infected at higher prevalence, these included Trypoxylon deceptorium, Trypoxylon minus, Hoplitis leucomelana and Hylaeus moricei (all considered new host records). We identified three fungal species, Penicillium buchwaldii (72% of cases), Aspergillus pseudoglaucus (22%) and Penicillium quebecense (6%). When multibrooded nests were affected, only a part of individuals was infected in 62% of cases. The sampling site-specific infection rate reached up to 13%, thus fungal infections should be considered an important variable driving the abundance of gall inquilines. Infections of generalist host species were more frequent than those of reed gall specialists, suggesting that suboptimal conditions decreased the immunocompetence of non-specialized species, which only occasionally nest in reed galls and feed in reed beds.

  9. The Mystery of the Past Haunts Again: Jane Eyre and Eugenie Marlitt’s Die zweite Frau Le mystère du passé hante encore: l’influence de Jane Eyre sur Die zweite Frau d’Eugenie Marlitt

    2010-03-01

    Full Text Available Charlotte Brontë’s Jane Eyre is a classic in women’s fiction. When it was published in 1847, it made an immediate impact in mid-Victorian England, partly because it drew on the paradigmatic story of a romance heroine, partly because it interpreted the needs of the women of the time. Since then, the Thornfield Hall attic where Bertha Mason is kept hidden by the master of the house, Mr. Rochester, has become the metaphor of a feminine place of imprisonment and,at the same time, of rebellion against patriarchal rules.About thirty years after Jane Eyre, another woman writer published a book which evokes the haunting atmosphere of the Thornfield Hall theme, i.e., the German writer Eugenie Marlitt, the author of Die zweite Frau ( The second wife, 1874.Interestingly, Marlitt seems to recapture, while rewriting it, the character of Bertha within the context of German domestic fiction. Bothnovels explore indeed the issue of the imprisoned and socially marginalised woman in terms of ethnicity to show how gender roles are inevitably complicit with power relations. In Jane Eyre and Die zweite Frau the house motif is a pivotal element that leads to our understanding of the female characters, but it is above all the mystery that reverberates through the houses of the two novels, represented by two women, the Creole Bertha  and the Indian Lotusblume, which, being crucial to the articulation of the discursive thrust underlying the two narratives, discloses the multi-layered construction of femininity.Jane Eyre de Charlotte Brontë est un classique de la littérature féminine. Lors de sa publication en 1847, le roman eut un impact immédiat sur l’Angleterre victorienne, d’une part parce qu’il racontait l’histoire paradigmatique d’une héroïne de romance et d’autre part parce qu’il se faisait l’interprète des désirs des femmes de l’époque.

    The ability to maintain human brain explants in tissue culture was a critical step in the use of these cells for the study of central nervous system disorders. Ross G. Harrison (1870-1959) was the first to successfully maintain frog medullary tissue in culture in 1907, but it took another 38 years before successful culture of human brain tissue was accomplished. One of the pioneers in this achievement was Mary Jane Hogue (1883-1962). Hogue was born into a Quaker family in 1883 in West Chester, Pennsylvania, and received her undergraduate degree from Goucher College in Baltimore, Maryland. Research with the developmental biologist Theodor Boveri (1862-1915) in Würzburg, Germany, resulted in her Ph.D. (1909). Hogue transitioned from studying protozoa to the culture of human brain tissue in the 1940s and 1950s, when she was one of the first to culture cells from human fetal, infant, and adult brain explants. We review Hogue's pioneering contributions to the study of human brain cells in culture, her putative identification of progenitor neuroblast and/or glioblast cells, and her use of the cultures to study the cytopathogenic effects of poliovirus. We also put Hogue's work in perspective by discussing how other women pioneers in tissue culture influenced Hogue and her research.

  12. Janeites for a New Millennium: The Modernisation of Jane Austen on Film

    Directory of Open Access Journals (Sweden)

    2009-05-01

    Full Text Available The late twentieth century saw a surge in cinematic adaptations of Jane Austen’s novels, the films generating wide-spread interest and zeal from a new caste of modern-day Janeites, many of whom were previously unfamiliar with Austen’s work. While the notion of a Janeite culture based purely on motion picture renditions of the original novels is sure to displease literary purists, the purpose of this discussion is not to initiate a debate regarding our responsibility to remain faithful to Austen in her original form. Rather, this article identifies the type of cinematic alterations and emphases which render Austen films more appealing to a certain group of modern-day Janeites. It will be argued that modern-day audiences’ demand for recognisably modern protagonists necessitates the modernization of Austen on film. Thus, cinematic adaptations tend to emphasize Austen’s nascent feminism, re-imagining her heroines as more fiercely independent, lively and witty than their original incarnations. Through additional scenes, altered dialogue and substantial changes to the characters, film producers not only highlight the plight of women in the early nineteenth century, but also circumvent such restrictions by allowing their female protagonists the degree of independence demanded by modern-day audiences.

  13. Adaptation-induced Tourism for Consumers of Literature on Screen: the Experience of Jane Austen Fans

    2015-03-01

    Full Text Available My aim in this article is that of starting to relate the expanding research field of adaptation studies to the subject area of film-induced tourism. Adaptations are a specific typology of films: that is, films whose story was not originally intended for the screen but, more often than not, for the written page, and has, therefore, been ‘translated’ into a new medium. The phenomenon of adaptation has been at the center of a heated debate for a few years now, but the specific link between adaptation and tourism has not yet been studied in its own right. In my article I question why and how adaptations of literary texts for the screen can induce a desire to visit film locations (actual geographical places in readers who are also inclined to enjoy the experience of “literature on screen”. In order to do this, I focus on the case study of adaptations from Jane Austen’s novels and on a specific kind of tourists, the so called ‘Janeites’, or Austen fans.

    Bioenergy crops are well known for their ability to reduce greenhouse gas emissions and increase the soil carbon stock. Although such crops are often held to be in competition with food crops and thus raise the question of current and future food security, at the same time mitigation measures are required to tackle climate change and sustain local farming communities and crop production. However, in some cases the actions envisaged for specific pedo-climatic conditions are not always economically sustainable by farmers. In this frame, energy crops with high environmental adaptability and yields, such as giant reed (Arundo donax L.), may represent an opportunity to improve farm incomes, making marginal areas not suitable for food production once again productive. In so doing, three of the 17 Sustainable Development Goals (SDGs) of the United Nations would be met, namely SDG 2 on food security and sustainable agriculture, SDG 7 on reliable, sustainable and modern energy, and SDG 13 on action to combat climate change and its impacts. In this work, the response of giant reed in the marginal areas of an agricultural district of southern Italy (Destra Sele) and expected farm incomes under climate change (2021-2050) are evaluated. The normalized water productivity index of giant reed was determined (WP; 30.1gm -2 ) by means of a SWAP agro-hydrological model, calibrated and validated on two years of a long-term field experiment. The model was used to estimate giant reed response (biomass yield) in marginal areas under climate change, and economic evaluation was performed to determine expected farm incomes (woodchips and chopped forage). The results show that woodchip production represents the most profitable option for farmers, yielding a gross margin 50% lower than ordinary high-input maize cultivation across the study area.

    This paper presents a form to resolve a real problem of efficient material election in reed switch manufacturing. The carrying out of the consumer demands depends on the stochastic results of the classification process where each lot of switches is distributed into bins according to an electric measure value. Various glass types are employed for the switch manufacturing. The effect caused by the glass type variation on the switch classification results was investigated. Based on real data statistic analysis, the problem is reduced to the lot number minimizing taking into consideration the glass type, and interpreted as a bin packing problem generalization. On difference to the classic bin packing problem, in the considered case, an item represents a set of pieces; a container is divided into a number of bins (sub-containers); the bin capacity is variable; there are the assignment restrictions between bins and sets of pieces; the items are allowed to be fragmented into bins and containers. The problem has a high complexity. A heuristic offline algorithm is proposed to find the quantity, types and packing sequence of containers, the item fragments associated with containers and bins. The bin capacities do not affect the algorithm.

    Full Text Available Resistance strategies of clonal organs, and parent and offspring shoots of Phragmites australis (common reed to heavy metal pollution in soils are not well known. To clarify the tolerance or resistance strategies in reeds, we conducted a pot experiment with five levels of Pb concentration (0∼4,500 mg kg−1 in flood and drought conditions. Lead toxicity had no inhibitory effect on the number of offspring shoots in flood environment; however, biomass accumulation, and photosynthetic and clonal growth parameters were inhibited in both water environment. At each treatment of Pb concentration, offspring shoots had greater biomass and higher photosynthesis indicators than parent shoots. The lowest Pb allocation was found in rhizomes. More of the Pb transported to above-ground parts tended to accumulate in parent shoots rather than in offspring shoots. Biomass and photosynthesis of offspring shoots, rhizome length, and the number of buds, rhizomes and offspring shoots in the flooded treatment were significantly greater than those in the drought treatment. Our results indicated that the tolerance strategies used by reeds, including higher biomass accumulation and photosynthesis in offspring shoots, low allocation of Pb in rhizomes and offspring shoots, and stable clonal growth, maintained the stability of population propagation and productivity, improving the resistance of reeds to Pb pollution in flood environment. However, the resistance or tolerance was significantly reduced by the synergistic effect of Pb and drought, which significantly inhibited biomass accumulation, photosynthesis, and clonal growth of reeds.

    The goal of this experiment was to excite and measure, in a noncontact manner, the vibrational modes of the reed from a reed organ pipe. To perform ultrasound stimulated excitation, two ultrasound beams in air of different frequencies were directed at the reed; the audio-range beat frequency between these ultrasound beams induced vibrations. The resulting vibrational deflection shapes were measured with a scanning vibrometer. The modes of any relatively small object can be studied in air using this technique. For a 36 mm by 7 mm clamped brass reed cantilever, displacements and velocites of 5 μ and 4 mm/s could be imparted at the fundamental frequency of 145 Hz. Using the same ultrasound transducer, excitation across the entire range of audio frequencies was obtained, which was not possible using audio excitation with a speaker. Since the beam was focused on the reed, ultrasound stimulated excitation eliminated background effects observed during mechanical shaker excitation, such as vibrations of clamps and supports. We will discuss the results obtained using single, dual, and confocal ultrasound transducers in AM and unmodulated CW modes, along with results obtained using a mechanical shaker and audio excitation using a speaker.

  19. NRC [Nuclear Regulatory Commission] staff evaluation of the General Electric Company Nuclear Reactor Study (''Reed Report'')

    International Nuclear Information System (INIS)

    1987-07-01

    In 1975, the General Electric Company (GE) published a Nuclear Reactor Study, also referred to as ''the Reed Report,'' an internal product-improvement study. GE considered the document ''proprietary'' and thus, under the regulations of the Nuclear Regulatory Commission (NRC), exempt from mandatory public disclosure. Nonetheless, members of the NRC staff reviewed the document in 1976 and determined that it did not raise any significant new safety issues. The staff also reached the same conclusion in subsequent reviews. However, in response to recent inquiries about the report, the staff reevaluated the Reed Report from a 1987 perspective. This re-evaluation, documented in this staff report, concluded that: (1) there are no issues raised in the Reed Report that support a need to curtail the operation of any GE boiling water reactor (BWR); (2) there are no new safety issues raised in the Reed Report of which the staff was unaware; and (3) although certain issues addressed by the Reed Report are still being studied by the NRC and the industry, there is no basis for suspending licensing and operation of GE BWR plants while these issues are being resolved

    Bradshaw, Tamika C.; Alizadeh, Hasan; Teymouri, Farzaneh; Balan, Venkatesh; Dale, Bruce E.

    Plant materials from the vegetative growth stage of reed canarygrass and the seed stage of reed canarygrass are pretreated by ammonia fiber expansion (AFEX) and enzymatically hydrolyzed using 15 filter paper units (FPU) cellulase/g glucan to evaluate glucose and xylose yields. Percent conversions of glucose and xylose, effects of temperature and ammonia loading, and hydrolysis profiles are analyzed to determine the most effective AFEX treatment condition for each of the selected materials. The controls used in this study were untreated samples of each biomass material. All pretreatment conditions tested enhanced enzyme digestibility and improved sugar conversions for reed canarygrass compared with their untreated counterparts. Based on 168 h hydrolysis results using 15 FPU Spezyme CP cellulase/g glucan the most effective AFEX treatment conditions were determined as: vegetative growth stage of reed canarygrass—100°C, 60% moisture content, 1.2∶1 kg ammonia/kg of dry matter (86% glucose and 78% xylose) and seed stage of reed canarygrass—100°C, 60% moisture content, 0.8∶1 kg ammonia/kg of dry matter (89% glucose and 81% xylose). Supplementation by commercial Multifect 720 xylanase along with cellulase further increased both glucose and xylose yields by 10-12% at the most effective AFEX conditions.

  1. Position indicating systems and reed contact unit assemblies for such systems

    Foxworthy, M.K.

    1980-01-01

    Specifications are given for a position indicating system for determining the position of a movable member inside a sealed container such as the position of a control rod in a nuclear reactor. The system comprises a magnetic flux producing member mounted to the movable member so as to move with it, a series of magnetic reed contact units mounted along the outside of the sealed container to be individually actuated by the flux producer as the movable member moves within the sealed container to indicate the position of this member. Each of the reed contact units is connected to a source of alternating electric current to produce a magnetic flux field to minimize the flux differential between the actuated and unactuated reed contact positions. A second aspect of the invention provides for a low operating flux differential reed contact unit assembly for a position indicating system such that it is actuated by the magnetic member at one magnetic flux level and deactivated at a second level. There is a source of alternating current connected to a coil surrounding the reed contact unit so as to produce an alternating magnetic flux with amplitude less than the difference between the two levels. Variations are given, also diagrams and benefits. (U.K.)

    Many studies have been conducted recently on an integrated hybrid actuator due to the increasing need for unmanned aircraft and guided weapons. In this study, flow distribution was analyzed for a reed valve which was used for flow regulation to improve the performance of the actuator. By using a Fluid structural interaction (FSI) technique with Computational fluid dynamics (CFD) having a moving mesh, numerical analysis was performed according to the thickness, shape and driving frequency of the reed valve. From the calculated results, the maximum performance of the reed valve was found at the valve thickness of 0.15 mm and the driving frequency of 250 Hz for a no-load state. The optimum thickness and shape for the valve for each driving frequency were also realized.

    MRI is established as an important diagnostic tool in medicine. However, the presence of a cardiac pacemaker is usually regarded as a contraindication for MRI due to safety reasons. The aim of this study was to investigate the state of a pacemaker reed switch in different orientations and positions in the main magnetic field of 0.5-, 1.5-, and 3.0-T MRI scanners. Reed switches used in current pacemakers and ICDs were tested in 0.5-, 1.5-, and 3.0-T MRI scanners. The closure of isolated reed switches was evaluated for different orientations and positions relative to the main magnetic field. The field strengths to close and open the reed switch and the orientation dependency of the closed state inside the main magnetic field were investigated. The measurements were repeated using two intact pacemakers to evaluate the potential influence of the other magnetic components, like the battery. If the reed switches were oriented parallel to the magnetic fields, they closed at 1.0 +/- 0.2 mT and opened at 0.7 +/- 0.2 mT. Two different reed switch behaviors were observed at different magnetic field strengths. In low magnetic fields ( 200 mT), the reed switches opened in 50% of all tested orientations. No difference between the three scanners could be demonstrated. The reed switches showed the same behavior whether they were isolated or an integral part of the pacemakers. The reed switch in a pacemaker or an ICD does not necessarily remain closed in strong magnetic fields at 0.5, 1.5, or 3.0 T and the state of the reed switch may not be predictable with certainty in clinical situations.

    Fourier-like transforms over GF(F sub n), where F sub n = 2(2n) + 1 is a Fermat prime, are applied in decoding Reed-Solomon codes. It is shown that such transforms can be computed using high-radix fast Fourier transform (FFT) algorithms requiring considerably fewer multiplications than the more usual radix 2 FFT algorithm. A special 256-symbol, 16-symbol-error-correcting, Reed-Solomon (RS) code for space communication-link applications can be encoded and decoded using this high-radix FFT algorithm over GF(F sub 3).

  11. Differences in breeding bird assemblages related to reed canary grass cover cover and forest structure on the Upper Mississippi River

    2017-01-01

    Floodplain forest of the Upper Mississippi River provides habitat for an abundant and diverse breeding bird community. However, reed canary grass Phalaris arundinacea invasion is a serious threat to the future condition of this forest. Reed canary grass is a well-known aggressive invader of wetland systems in the northern tier states of the conterminous United States. Aided by altered flow regimes and nutrient inputs from agriculture, reed canary grass has formed dense stands in canopy gaps and forest edges, retarding tree regeneration. We sampled vegetation and breeding birds in Upper Mississippi River floodplain forest edge and interior areas to 1) measure reed canary grass cover and 2) evaluate whether the breeding bird assemblage responded to differences in reed canary grass cover. Reed canary grass was found far into forest interiors, and its cover was similar between interior and edge sites. Bird assemblages differed between areas with more or less reed canary grass cover (.53% cover breakpoint). Common yellowthroat Geothlypis trichas, black-capped chickadee Parus atricapillus, and rose-breasted grosbeak Pheucticus ludovicianus were more common and American redstart Setophaga ruticilla, great crested flycatcher Myiarchus crinitus, and Baltimore oriole Icterus galbula were less common in sites with more reed canary grass cover. Bird diversity and abundance were similar between sites with different reed canary grass cover. A stronger divergence in bird assemblages was associated with ground cover ,15%, resulting from prolonged spring flooding. These sites hosted more prothonotary warbler Protonotaria citrea, but they had reduced bird abundance and diversity compared to other sites. Our results indicate that frequently flooded sites may be important for prothonotary warblers and that bird assemblages shift in response to reed canary grass invasion.

    Full Text Available Las novelas de Jane Austen siguen inspirando nuevos relatos cinematográficos pues éstos toman sus historias o sus personajes y los adaptan a contextos culturales y axiológicos actuales de gran diversidad. Es el caso de la novela de Orgullo y Prejuicio de la que se han realizado numerosas adaptaciones clásicas, así como que ha sido objeto de referencia en películas, en trabajos literarios y de adaptaciones postmodernas. Uno de estos trabajos postmodernos es Persiguiendo a Jane Austen una serie inglesa que nos adentra en el mundo de la Regencia a través de las vivencias de una mujer contemporánea que descubre una puerta que comunica ambos mundos y que le permite vivir la historia de Austen bajo la piel de Elizabeth Bennet. A lo largo de este trabajo se realizará un análisis comparado entre esta adaptación postmoderna y su referente literario para comprobar cómo influyen las ideas de la Postmodernidad en un clásico de la literatura decimonónica, pues es una tendencia que nos ayuda a replantearnos un periodo de la historia y a reinterpretar el contexto de la novela original a uno distinto y original.

    Deng, Robert H.; Costello, Daniel J., Jr.

    1987-01-01

    A problem in designing semiconductor memories is to provide some measure of error control without requiring excessive coding overhead or decoding time. In LSI and VLSI technology, memories are often organized on a multiple bit (or byte) per chip basis. For example, some 256 K bit DRAM's are organized in 32 K x 8 bit-bytes. Byte-oriented codes such as Reed-Solomon (RS) codes can provide efficient low overhead error control for such memories. However, the standard iterative algorithm for decoding RS codes is too slow for these applications. The paper presents a special decoding technique for double-byte-error-correcting, triple-byte-error-detecting RS codes which is capable of high-speed operation. This technique is designed to find the error locations and the error values directly from the syndrome without having to use the iterative algorithm to find the error locator polynomial.

  14. Survival during the Breeding Season: Nest Stage, Parental Sex, and Season Advancement Affect Reed Warbler Survival.

    Kaja Wierucka

    Full Text Available Avian annual survival has received much attention, yet little is known about seasonal patterns in survival, especially of migratory passerines. In order to evaluate survival rates and timing of mortality within the breeding season of adult reed warblers (Acrocephalus scirpaceus, mark-recapture data were collected in southwest Poland, between 2006 and 2012. A total of 612 individuals (304 females and 308 males were monitored throughout the entire breeding season, and their capture-recapture histories were used to model survival rates. Males showed higher survival during the breeding season (0.985, 95% CI: 0.941-0.996 than females (0.869, 95% CI: 0.727-0.937. Survival rates of females declined with the progression of the breeding season (from May to August, while males showed constant survival during this period. We also found a clear pattern within the female (but not male nesting cycle: survival was significantly lower during the laying, incubation, and nestling periods (0.934, 95% CI: 0.898-0.958, when birds spent much time on the nest, compared to the nest building and fledgling periods (1.000, 95% CI: 1.00-1.000, when we did not record any female mortality. These data (coupled with some direct evidence, like bird corpses or blood remains found next to/on the nest may suggest that the main cause of adult mortality was on-nest predation. The calculated survival rates for both sexes during the breeding season were high compared to annual rates reported for this species, suggesting that a majority of mortality occurs at other times of the year, during migration or wintering. These results have implications for understanding survival variation within the reproductive period as well as general trends of avian mortality.

    The noise level of the refrigerator compressor has received more and more attention in recent years. As the key component of a compressor, reed valve is its main noise source. In this paper, a new noise reduction technology of coating on reed valve surface is proposed and verified by experiments. Firstly, the reed valves were coated, and their surface characteristics were checked. Then, the refrigerator compressor p-V diagram test was carried out to investigate the influence of doped diamond-like carbon (DLC) coating on power consumption. Finally, the noise test rig for the refrigerator compressor was set up. Based on the standard test method, noise spectrum was measured in a semi-anechoic room under standard working condition. Research results showed that the compressor noise was significantly reduced by 1.8dB (A) after coating. Moreover, the effect of aerodynamic noise reduction at suction side is better than that at discharge side. However, the influence of the film thickness on noise reduction value is little. The COP was reduced by 0.6% as compared to the compressor with uncoated reed valves.

    2013-01-01

    Interactions between avian hosts and brood parasites can provide a model for how animals adapt to a changing world. Reed warbler (Acrocephalus scirpaceus) hosts employ costly defenses to combat parasitism by common cuckoos (Cuculus canorus). During the past three decades cuckoos have declined markedly across England, reducing parasitism at our study site (Wicken Fen) from 24% of reed warbler nests in 1985 to 1% in 2012. Here we show with experiments that host mobbing and egg rejection defenses have tracked this decline in local parasitism risk: the proportion of reed warbler pairs mobbing adult cuckoos (assessed by responses to cuckoo mounts and models) has declined from 90% to 38%, and the proportion rejecting nonmimetic cuckoo eggs (assessed by responses to model eggs) has declined from 61% to 11%. This is despite no change in response to other nest enemies or mimetic model eggs. Individual variation in both defenses is predicted by parasitism risk during the host’s egg-laying period. Furthermore, the response of our study population to temporal variation in parasitism risk can also explain spatial variation in egg rejection behavior in other populations across Europe. We suggest that spatial and temporal variation in parasitism risk has led to the evolution of plasticity in reed warbler defenses. PMID:24299407

    Full Text Available We studied reed bed development in Matsalu wetland and the Kasari River delta, Estonia, since the late 18th century using historical schemes, topographical maps and aerial photographs. Our aim was to understand the mechanisms controlling reed distribution in Matsalu wetland, the largest coastal wetland of the eastern Baltic Sea occupying an area of about 25 km2. Natural development of the reed bed in Matsalu Bay and the Kasari delta is mainly controlled by shoreline displacement due to post-glacial neotectonic land uplift. The dredging of the Kasari delta in the 1920s–1930s caused a rapid seaward migration of reed bed communities due to the dispersal of fragmented rhizomes on the shallow sea bottom and along the canal banks reaching Matsalu Bay, while the landward parts of the former wetland were occupied by meadow communities. The expansion of the reed bed started in between the 1951s and 1970s and a maximum extent of 27 km2 was gained by the late 1970s at the peak of eutrophication. In the last decades the reed bed development has been influenced by sea level rise and increased intensity of cyclonic activity in the Baltic Sea, which has caused the deterioration of the reed bed that was weakened by eutrophication due to nutrient inflow from agricultural landscapes mainly in the 1960s–1980s.

    Wetland plants such as Phragmites australis has been used to treat acid mine drainage (AMD) contaminated soil which is a serious environmental issue worldwide. This project investigated metal plaque content(s) and metal uptake in reeds grown in an AMD field in winter and spring. The results indicated that the level of Fe plaque was much higher than Mn and Al plaque as the soil contained more Fe than Al and Mn. The amounts of Mn and Al plaque formed on reeds in spring were not significantly different from that in winter (p > .05). However, more Fe plaque was formed on reeds collected in spring. The concentrations of metals in underground organs were positively related to the metal levels in soils. More Mn and Al transferred to the aboveground tissues of reeds during the spring while the Fe levels in reeds did not significantly vary with seasons. Roots and rhizomes were the main organs for Fe sequestration (16.3 ± 4.15 mg/g in roots in spring) while most Al was sequestered in the shoots of reeds (2.05 ± 0.09 mg/g in shoots in spring). Further research may be needed to enhance the translocation of metals in reeds and increase the phytoremediation efficiency.

  10. An introduction to constructed wetlands (reed beds) sustainable low cost wastewater treatment plants

    The use of 'conventional' wastewater treatment technology (trickling filters and activated sludge) in developing countries has often been unsuccessful due to high cost, complex operating requirements and expensive maintenance procedures. Typical examples of such projects are wastewater plants in Islamabad and Karachi. Actually the conventional systems, such as trickling filters and activated sludge plants were developed to address the concerns about organic pollution of natural water bodies in western temperate climates, rather than the reduction of organic matter as well as pathogens which is often a priority in developing countries. Pakistan, being a developing country cannot and should not follow the western technology blindly but needs the use of a ppropriate technology . Appropriate technology is defined as a treatment system which meets the following criteria: Affordable: Total amount costs, including capital, operation, maintenance and depreciation are within the user's ability to pay. Operable: Operation of the system is possible with locally available labor and support. Reliable: Effluent quality requirements can be met consistently. Currently there are a limited number of appropriate technologies for small communities, which should be considered by a community and their designers. These include conventional and non-conventional systems such as stabilization ponds or lagoons, slow sand filters, land treatment systems, and wetlands (natural or constructed). The non-conventional systems often utilize 'ecological' treatment mechanism (such as aquatic systems or wetlands) and do not have the mechanical parts or energy requirements of conventional systems. Waste Stabilization Ponds are one such solution but sometimes are constrained by land availability, topography, and are not environment friendly. In such locations, natural or constructed wetlands (Reed Beds) could provide an alternative technology. It is what we call a LOW technology, rather than HI TECH

  11. Identification, synthesis and mass spectrometry of a macrolide from the African reed frog Hyperolius cinnamomeoventris

    Full Text Available The contents of the gular glands of the male African reed frog Hyperolius cinnamomeoventris consist of a mixture of aliphatic macrolides and sesquiterpenes. While the known macrolide gephyromantolide A was readily identified, the structure of another major component was suggested to be a tetradecen-13-olide. The synthesis of the two candidate compounds (Z-5- and (Z-9-tetradecen-13-olide revealed the former to be the naturally occurring compound. The synthesis used ring-closing metathesis as key step. While the Hoveyda–Grubbs catalyst furnished a broad range of isomeric products, the (Z-selective Grubbs catalyst lead to pure (Z-products. Analysis by chiral GC revealed the natural frog compound to be (5Z,13S-5-tetradecen-13-olide (1. This compound is also present in the secretion of other hyperoliid frogs as well as in femoral glands of male mantellid frogs such as Spinomantis aglavei. The mass spectra of the synthesized macrolides as well as their rearranged isomers obtained during ring-closing metathesis showed that it is possible to assign the location of the double bond in an unsaturated macrolide on the basis of its EI mass spectrum. The occurrence of characteristic ions can be explained by the fragmentation pathway proposed in the article. In contrast, the localization of a double bond in many aliphatic open-chain compounds like alkenes, alcohols or acetates, important structural classes of pheromones, is usually not possible from an EI mass spectrum. In the article, we present the synthesis and for the first time elucidate the structure of macrolides from the frog family Hyperoliidae.

    Full Text Available Dans le quatrième chapitre de son ouvrage intitulé Brontë Transformations (1996, Patsy Stoneman révèle l’importance des reprises et transformations dont a fait l’objet Jane Eyre (1847 de Charlotte Brontë dans diverses pièces de théâtre, romans et films depuis sa publication initiale. L’un des avatars les plus intéressants mentionné par P. Stoneman est Rebecca d’Alfred Hitchcock (1940 d’après le roman à succès éponyme de Daphné Du Maurier paru en 1938. Parmi les nombreux éléments communs au roman de Brontë et au film d’Hitchcock figurent l’héroïne orpheline consciente de son physique ordinaire, un personnage masculin maussade doté d’une épouse “présente-absente” et une intendante dont le tempérament influence l’atmosphère du manoir dans lequel l’héroïne réside temporairement. Un autre point commun, plus difficile à déceler car profondément intégré à chaque œuvre, est le portrait de l’héroïne en oiseau prisonnier. Ce(tte subtile trope/métaphore mérite d’être remarqué(e car non seulement l’image constitue un lien entre les deux œuvres mais elle permet aussi, dans ses diverses manifestations, de les différencier. Tandis que dans Jane Eyre, l’image de l’oiseau apparaît chaque fois que Jane s’échappe d’un lieu qui l’emprisonne, celle de la cage s’avère être l’élément dominant dans le film d’Hitchcock, imposant finalement des limites infranchissables à la liberté de l’héroïne.

R&S aims to foster learning, personal growth and civic engagement among youth members through service activities and environmental education. Despite its promise as a youth development program and its rapid expansion into 100 countries, little is known about R&S’s impact on youth development. In this study, we explore R&S programs in China and Tanzania, two countries that are maximally different from the U.S. in important cultural and contextual factors. Through qualitative and quantitative methods we describe the programs, their practices, and perceptions of their impact on youths’ personal and social development (cognitive and social competence, leadership, self-efficacy, citizenship and social responsibility. Additionally, we highlight the importance of sociocultural and ecological factors when developing and evaluating youth programs.

    Full Text Available This paper examines the contributions of two British architects, Maxwell Fry and Jane Drew in the development of built environment in Nigeria after World War II. It analyses the historical development of the built environment in Nigeria’s public space with respect to modernize infrastructures such as banks, schools, teachers training colleges and the university needed in support of the colonial administration in Nigeria. The agitation of the nationalists and postwar reconstruction facilitated and encouraged the British Empire to develop the edifice or structures that would be suitable for the environment. This, to a large extent, influenced the Nigerian architecture and built environment. Their design principles yielded functional institutional spaces and a hybrid aesthetics that signifies modernist construction and colonial influence. The paper concludes that the designs of both Fry and Drew represent a milestone and significant contribution to the development of built environment in colonial Nigeria.

    Full Text Available Thousands of overseas Korean adoptees return to Korea temporarily each year in search of their true origin, but few choose to stay permanently. A prominent member of this small community is Jane Jeong Trenka, author of two memoirs: The Language of Blood (2003 and Fugitive Visions: An Adoptee’s Return to Korea (2009. This article analyses Trenka’s literary struggle for permanence in Fugitive Visions through theories on Korean ethnic national identity. Using Marshall McLuhan’s idea of media as the ‘extension of man’, it explores the symbiotic relationship between literary media and identity, connecting colonial-era writings on Korean ethnic nationalism to Trenka’s portrayal of transnational return.

    . In this process will the silica problem in the chemical recovery process also be reduced. For integrating a grass cooking line in existing pulp and paper mills also the sulphate cooking process, have been developed for use with reed canary grass. Pulp produced from fractionated reed canary grass can easily be bleached to full brightness of 90 % ISO with environmentally friendly bleaching processes and technically well documented chemical recovery systems can be used. Reed canary grass contains relatively short fibres which can replace hardwood fibres in high quality printing papers. The pulp produced was evaluated for end use as board (white-top liner) and fine paper. The mill produced reed canary grass pulp had better optical properties and bulk than pulp produced in laboratory although it was not possible to optimise all parameters during the short time the mill was available for the trial. The white top liner tests with mill produced pulp showed that the excellent good light scattering make it possible to produce board with equal quality using less fibre compared to what is needed using birch pulp. Reed canary grass pulp is thus a promising new fibre for board production. The mill produced pulp had also equal or better quality than pulp from birch and disc mill processed reed canary grass pulp can also compete with Eucalyptus pulp. The intermediate processed fuel raw material showed good possibilities to be processed to upgraded biofuels as powder, briquettes and pellets although more research have to be done concerning technology development. Using additives helps to form good quality pellets. Sugar molasses helped to make better quality pellets using less energy. But this is of course extra cost in pellet making. Optimisation of RCG meal fraction pelletising needs more tests, but with these pilot tests it was shown that RCG meal fraction can be pelletised also without any additives and good quality pellets can be formed. Reed canary grass pellets have a high ash

    The reliability and accuracy of the information on control rod position are very important to the reactor safety and the design of the core protection system. A survey on the RSPT(Reed Switch Position Transmitter) type control rod position indication system and its actual implementation in the exiting nuclear power plants in Korea was performed first. The control rod position indicator having the high performance for SMART was developed on the basis of RSPT technology identified through the survey. The hysteresis of reed switches is one of the important factors in a repeat accuracy of control rod position indication. In this study, the hysteresis of reed switches is introduced and the design method using the magnetic analysis of reed switches in presented

    Giant reed (Arundo donax L.) is a perennial rhizomatous grass that can be regarded as an ideal crop for bioenergy production, owing to several intrinsic characteristics. Despite to the promising yield results obtained in many plot experiments, the cultivation of giant reed at field scale is still a challenge. Owing to the floral sterility of the species, rhizome propagation has been predominantly used to establish field plots experiments, although this method is unpractical and monetarily expensive. Giant reed is a hydrophytic plant that typically spread in riparian systems by flood-mediated fragmentation and dispersal of vegetative propagules. Since giant reed propagation is strictly dependent on temporary abundance of water, this plant characteristic might be exploited for fostering the diffusion of giant reed as a bioenergy field crop. The objectives of this paper were: i) to disseminate some techniques for shoot cutting propagation of giant reed in water and in moist soil; ii) to address the critical points that remain to be solved for a widespread diffusion of this species as a bioenergy field crop.

The soil physicochemical properties, enzyme activities (i.e. urease, invertase, polyphenol oxidase, alkaline phosphatase and cellulase and soil microbial diversity were assayed before and after the exposure experiment. Compared to the river water irrigated controls (CKs, bleaching wastewater application has no marked influence on soil pH, but significantly increased soil Na+, total halogen and absorbable organic halogen (AOX contents, which induced the increasing of soil electrical conductivity. Furthermore, soil enzyme activities displayed significant variation (except for polyphenol oxidase. Bleaching wastewater irrigation decreased Sorenson’s pairwise similarity coefficient (Cs, which indicated the changes of the structure of bacterial and fungal communities. However, only the diversity of bacterial community was inhibited and has no effect on the diversity of fungal community, as evidenced by the calculated Shannon–Wiener index (H.

    2008-01-01

    The Reed Switch Position Transmitter (RSPT) is used as a position indicator for the control rod in commercial nuclear power plants made by ABB-CE. But this position indicator has some problems when directly adopting it to the integral reactor. The Control Element Drive Mechanism (CEDM) for the integral reactor is designed to raise and lower the control rod in steps of 2mm in order to satisfy the design features of the integral reactor which are the soluble boron free operation and the use of a nuclear heating for the reactor start-up. Therefore the resolution of the position indicator for the integral reactor should be achieved to sense the position of the control rod more precisely than that of the RSPT of the ABB-CE. This paper adopts seismic resistance reed switches to the position indicator in order to reduce the damages or impacts during the handling of the position indicator and earthquake

  7. The vibrating reed frequency meter: digital investigation of an early cochlear model

    Directory of Open Access Journals (Sweden)

    Andrew Bell

    2015-10-01

    Full Text Available The vibrating reed frequency meter, originally employed by Békésy and later by Wilson as a cochlear model, uses a set of tuned reeds to represent the cochlea’s graded bank of resonant elements and an elastic band threaded between them to provide nearest-neighbour coupling. Here the system, constructed of 21 reeds progressively tuned from 45 to 55 Hz, is simulated numerically as an elastically coupled bank of passive harmonic oscillators driven simultaneously by an external sinusoidal force. To uncover more detail, simulations were extended to 201 oscillators covering the range 1–2 kHz. Calculations mirror the results reported by Wilson and show expected characteristics such as traveling waves, phase plateaus, and a response with a broad peak at a forcing frequency just above the natural frequency. The system also displays additional fine-grain features that resemble those which have only recently been recognised in the cochlea. Thus, detailed analysis brings to light a secondary peak beyond the main peak, a set of closely spaced low-amplitude ripples, rapid rotation of phase as the driving frequency is swept, frequency plateaus, clustering, and waxing and waning of impulse responses. Further investigation shows that each reed’s vibrations are strongly localised, with small energy flow along the chain. The distinctive set of equally spaced ripples is an inherent feature which is found to be largely independent of boundary conditions. Although the vibrating reed model is functionally different to the standard transmission line, its cochlea-like properties make it an intriguing local oscillator model whose relevance to cochlear mechanics needs further investigation.

    2014-12-01

    Full Text Available The abrasion processing of shores is a pressing problem of large water basins of the Lower Volga region and other Russian regions. About 3 km2 of shoreland is annually lost in the zone of the Volgograd water basin as a result of this process. The existing methods of shores protection are connected with the creation of concrete structures having a high level of erosion resistance. They are extremely expensive and in most cases they are not affordable for rural municipalities suffering from abrasion. The authors offer cheap and environmentally friendly way of protecting the shores of large water basins from abrasion. The method is based on the plantation of a common reed strip on a water basin’s shallow. The biological characteristics of common reed as the main component of shore protection structures are described. The terms and milestones of the work in the conditions of the Volgograd water basin are developed. The main result of applying our methodology is the complete cessation of abrasion processing of the shore at the corresponding piece of land. The authors overview the positive qualities of reed plantations, their biocenotic, barrier and waterproof role in on-shore ecosystems. The application of the described method will allow saving for the national economy dozens of hectares of valuable shore lands annually, in particular, irrigated cropland, settlement lands, infrastructure. In addition to the direct benefits associated with the conservation of land resources, the intensity of adverse processes associated with erosion of shores (water basin muddying, deterioration of sanitary qualities of water will decrease. Due to the wide geographic spread of common reed described in the present work, the technology of shores stabilization can be applied at almost all lowland water basins of Russia.

  9. Reduction of the suction losses through reed valves in hermetic reciprocating compressors using a magnet coil

    Reed valves are widely used in hermetic reciprocating compressors and are responsible for a large part of the thermodynamic losses. Especially, the suction valve, which is opened nearly during the whole suction stroke, has a big potential for improvement. Usually, suction valves are opened only by vacuum created by the moving piston and should be closed before the compression stroke starts to avoid a reversed mass-flow through the valve. Therefore, the valves are prestressed, which results on the other hand in a higher flow resistance. In this work, a suction valve is investigated, which is not closed by the preload of the valve but by an electromagnetic coil located in the suction muffler neck. Shortly before the piston reaches its bottom dead centre, voltage is applied to the coil and a magnetic force is generated which pulls the valve shut. Thereby, the flow resistance through the valve can be reduced by changing the preload on the reed valve because it is no longer needed to close the valve. The investigation of this adapted valve and the electromagnetic coil is firstly done by numerical simulations including fluid structure interactions of the reed valves of a reciprocating compressor and secondly by experiments made on a calorimeter test bench.

    Reed canary grass (RCG) is a bio-energy crop with large potential. It is a 1.5 . 2.5 m tall grass that is harvested in spring when it is grown as a fuel. At spring harvest it yields 3 . 10 ton field dried material per ha and year. One disadvantage when reed canary grass is used as a fuel is the high ash content, 5-10 %. This means that large quantities of ash have to be deposited which is expensive, about 1000 SEK/ton. However, since reed canary grass ash contains reasonable amounts of plant nutrients like phosphorous (P), potassium (K) and magnesium (Mg) it could be recycled as fertilizer in agriculture. The ash can be used without any pretreatment since, in agriculture, plant availability is desirable. The aim of this project, was to evaluate a field experiment, where ash was used as a fertilizer in reed canary grass. The experiment was established at the SLU research station in Umea, Sweden in the spring 2002. Three different fertilizer treatments were applied: Treatment A was fertilized with an ash produced by combustion of RCG together with municipal wastes (paper, plastic, leather), treatment B, an ash from combustion of RCG, and for treatment C commercial fertilizers were used. In total, 100 kg ha-1 of nitrogen (N), 15 kg ha-1 of phosphorous (P) and 80 kg ha-1 of potassium (K), were applied each year in all treatments. The amount of ash in treatment A and B was calculated from the chemical analysis of the ashes to be equal to the required amount of P, while K and N were supplied also by commercial fertilizers. [Table 1. Composition of the ashes] Literature study: There is a lack of knowledge about fertilization with reed canary grass ash, since few experiments have been conducted. The composition of reed canary grass is dependent of harvest date and the soil substrate. The amount of ash and the amount of harmful substances such as potassium and chloride generally decreases over winter, giving an increased fuel quality from spring harvest compared to autumn

  11. Past and Present Resource Disputes in the South China Sea: The Case of Reed Bank

    Full Text Available In 2012, tensions flared between China and the Philippines over plans to drill for oil in the Reed Bank, a disputed shoal in the South China Sea, rekindling fears about the possibility of military conflict over the area’s energy resources. This article shows that international controversy centering on the Reed Bank’s hydrocarbon reserves initially emerged during the oil crisis of the 1970s, when the pursuit of energy resources transformed the islets into a hotly contested area. As in recent years, oil exploration by multinational corporations in conjunction with the Philippines catalyzed international disputes. Vigorous protests from China and other nations that lay claim to territories in the South China Sea prompted the Philippines to assert its own jurisdictional claims. The territorial dispute pushed claimants to the brink of military confrontation in the 1970s, yet armed conflict failed to materialize. By examining the initial round of tensions surrounding oil exploration at Reed Bank, this article situates the current international competition for the South China Sea’s energy resources in historical perspective. Analyzing past disputes and their ultimate resolution offers insights into the dynamics of present tensions, while making it possible to critically engage with arguments predicting future “resource wars” in the South China Sea.

  12. Invertebrate populations in miscanthus (Miscanthusxgiganteus) and reed canary-grass (Phalaris arundinacea) fields

    Monitoring of invertebrates at four field sites in Herefordshire, England, growing miscanthus and reed canary-grass was carried out in 2002, 2003 and 2004 to investigate the ecological impact of these crops on ground beetles, butterflies and arboreal invertebrates. Ground beetles were sampled by pitfall trapping; and arboreal invertebrates by sweep netting and stem beating. The Centre for Ecology and Hydrology's Butterflies Monitoring Scheme methodology was used to record butterflies. The effects of the biomass crops on invertebrates were indirect, through the use of weeds as food resources and habitat. The greater diversity of weed flora within miscanthus fields than within reed canary-grass fields had a greater positive effect on invertebrates. Ground beetles, butterflies and arboreal invertebrates were more abundant and diverse in the most floristically diverse miscanthus fields. The difference in crop architecture and development between miscanthus and reed canary-grass was reflected in their differences in crop height and ground cover early on in the season. However, most of the difference in arthropod abundance between the two crops was attributed to the difference in the agronomic practice of growing the crops such as plant density, and the effect of this on weed growth. Since perennial rhizomatous grasses require a single initial planting and related tillage, and also no major chemical inputs; and because the crops are harvested in the spring and the land is not disturbed by cultivation every year, the fields were used as over-wintering sites for invertebrates suggesting immediate benefits to biodiversity.

  15. Dale Reed with model in front of M2-F1

    Science.gov (United States)

    1967-01-01

    Dale Reed with a model of the M2-F1 in front of the actual lifting body. Reed used the model to show the potential of the lifting bodies. He first flew it into tall grass to test stability and trim, then hand-launched it from buildings for longer flights. Finally, he towed the lifting-body model aloft using a powered model airplane known as the 'Mothership.' A timer released the model and it glided to a landing. Dale's wife Donna used a 9 mm. camera to film the flights of the model. Its stability as it glided--despite its lack of wings--convinced Milt Thompson and some Flight Research Center engineers including the center director, Paul Bikle, that a piloted lifting body was possible. The lifting body concept evolved in the mid-1950s as researchers considered alternatives to ballistic reentries of piloted space capsules. The designs for hypersonic, wingless vehicles were on the boards at NASA Ames and NASA Langley facilities, while the US Air Force was gearing up for its Dyna-Soar program, which defined the need for a spacecraft that would land like an airplane. Despite favorable research on lifting bodies, there was little support for a flight program. Dryden engineer R. Dale Reed was intrigued with the lifting body concept, and reasoned that some sort of flight demonstration was needed before wingless aircraft could be taken seriously. In February 1962, he built a model lifting body based upon the Ames M2 design, and air-launched it from a radio controlled 'mothership.' Home movies of these flights, plus the support of research pilot Milt Thompson, helped pursuade the facilities director, Paul Bikle, to give the go-ahead for the construction of a full-scale version, to be used as a wind-tunnel model and possibly flown as a glider. Comparing lifting bodies to space capsules, an unofficial motto of the project was, 'Don't be Rescued from Outer Space--Fly Back in Style.' The construction of the M2-F1 was a joint effort by Dryden and a local glider manufacturer, the

    2013-01-01

    Full Text Available Due to its ability to accumulate metals, availability throughout the year and its large biomass, Phragmites australis (common reed is suitable for biomonitoring studies for the evaluation of load level of water ecosystem with trace metals. The heavy metals concentration in P.australis tissue can be several ten to several thousand times higher than those in the surrounding water. In this study we examined the content of heavy metals (Cd, Co, Cr, Cu, Mn, Ni, Pb, Zn, Sr and V in sediment, water and different organs of Phragmites australis collected from Lake Skadar, Montenegro, during different seasons of the year 2011. The highest concentrations of Sr were found in the leaves, while the other studied metals showed their highest concentrations in the roots. Thus, P. australis is considered a root bioaccumulation species. For most metals the concentration in roots and stems increases over time until the end of the growing season, and then decreases, while the concentration in leaves increases even after the growing season of the plant. If P. australis is used for phytoremediation purposes, then it should be harvested after the growing season because then the concentration of metals in the aboveground parts is maximal.

    Eta Farmacelia Nurulhady

    2017-04-01

    Full Text Available Abortion and violence are global issues, yet different culture might respond to the issues somewhat differently. This study aims to reveal the abortion and violence issues in Jane Martin’s Keely and Du in terms of pro-choice and pro life movements and see how Indonesian students reading the play respond to the issues. In the United States of America, the discussion of abortion issue can be grouped into two major categories: the pro-life and pro-choice. In Indonesia, the majority of people would be against abortion when it is not for medical reasons. The students reading Keely and Du find the play challenging their beliefs as religious people still keeping hold of eastern values. Having discussed the nature of pro-life and pro-choice movements, it is difficult for them to decide whether they are proponent of either one. Keely and Du is successfully provocative in offering insight on how abortion and violence issues cannot be judged in a black and white manner.

  19. Reporting on What Jane Saw 2.0: Female Celebrity and Sensationalism in Boydell’s Shakespeare Gallery

    Directory of Open Access Journals (Sweden)

    Janine Barchas

    2015-03-01

    Full Text Available This essay reports on ongoing efforts to build an accurate digital model of John Boydell’s popular Shakespeare Gallery precisely as it looked in August 1796—when a 20-year-old Jane Austen visited London’s sites, staying within a ten-minute walk from the gallery. The essay argues for the substantial difference between studying Boydell’s pictures in a paper volume (whether as lists, illustrations in books, or engraved folio plates and viewing them as an exhibition of paintings on walls, albeit virtual ones. For example, the digital reconstruction illuminated commissions from several female participants in Boydell’s male-dominated gallery, especially Angelica Kauffman (1741-1807 and Anne Seymour Damer (1749-1828. In addition, the essay also recounts how the celebrity of model Emma Hart/Hamilton (1765-1815 safeguarded one Boydell painting from oblivion while The Shakespeare Gallery proved the site of a strange form of self-promotion practiced by actress Mary Wells (1762-1829. Our digital visualization of an historic exhibition in 1796 brought the controversial celebrity of a few women artists into focus. In sum, this essay shows DH methodology in action while sampling what might be gleaned when digital tools serve historical scholarship in the humanities.

  1. The importance of biological oxidation of iron in the aerobic cells of the Wheal Jane pilot passive treatment system.

    Hall, G; Swash, P; Kotilainen, S

    2005-02-01

    The passive treatment system designed to treat the mine water discharge of the abandoned Wheal Jane tin mine in Cornwall consisted of a sequence of artificial wetland cells, an anaerobic cell and a final series of rock filters. Three systems were operated which differed only in the pre-treatment of the mine water before discharge to the aerobic wetland cells. The aerobic cells were designed to promote aerobic oxidation and precipitation of iron which could exceed a concentration of 100 mg/l in the raw mine water discharge. The largest investment of land area was to the artificial wetland cells and it was important to understand the processes of oxidation and precipitation of iron so that the performance of this aspect the pilot passive treatment plant (PPTP) could be managed as efficiently as possible. The generally low pH of the influent mine water and inevitable trend of decreasing pH due to hydrolysis of Fe(III) meant that distinguishing between biotic and abiotic mechanisms was fundamental for further design planning of passive treatment systems. This paper describes these observations.

  2. The two-dimensional vibrating reed technique. A study of anisotropic pinning in high-temperature superconductors

    2004-02-18

    In this work the anisotropy of the pinning forces of vortices in a-b plane of high temperature-supraconductors was examined. For this purpose vibrating reed with two degrees of freedom of the oscillation was constructed. The pinning forces were examined in single crystals of YBa{sub 2}Cu{sub 3}O{sub 7} and Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8}. The experiments with YBa{sub 2}Cu{sub 3}O{sub 7} show that at temperatures lower than 78 K the vortices are in a nonequilibrium state. This leads to a flux creep and to a drift of the resonance frequency with time. This prevents the comparison of resonance curves in different directions of oscillations. In Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8} single crystals the vortices are in more stable state, but the measurements of the resonance curves in different directions show no indication of the four-fold symmetry. At temperatures below 60 K a strong hysteresis of the resonance frequency and the resonance-oscillation amplitude was found in YBa{sub 2}Cu{sub 3}O{sub 7} crystals as a function of the magnetic field.

    Full Text Available En se départissant de la dichotomie victorienne manichéenne de l’ange du foyer et de la femme déchue pour éclairer les personnages de Jane et Bertha dans leur ouvrage pionnier The Madwoman in the Attic, Sandra Gilbert et Susan Gubar étudièrent la première épouse de Rochester, folle, comme le double subversif de Jane, faisant ainsi de Jane et de Bertha les facettes d’un seul et même personnage. Malgré le rejet moderniste des excès supposés de l’ère victorienne, Rebecca de Daphne du Maurier exploite une intrigue triangulaire similaire qui réinterprète et recrée Rochester, Bertha et Jane à travers Maxime de Winter, Rebecca et Mrs de Winter. Les conceptions victoriennes des féminités doubles, des doublets féminins pour ainsi dire, sont perpétuées et réactualisées à travers les textualités néo-victoriennes. Néanmoins, peut-on vraiment voir dans Bertha un personnage que Rochester tente d’assagir par l’entremise de la figure de l’ange du foyer, plutôt qu’un archétype de la femme déchue ? Jane n’est-elle pas destinée à découvrir le secret de Rochester avant de l’épouser ? Mrs de Winter a-t-elle à ce point le sens du sacré qu’elle ne cherche pas à entrer en concurrence avec Rebecca ? Rebecca est-elle à ce point élégante et infaillible qu’elle parvient à ne pas s’attirer le mépris de Maxime ? Cet article se propose d’examiner comment les héroïnes sont investies en termes de rôles sexuels dans l’écriture néo-victorienne – comment les rôles de l’ange du foyer et de la femme déchue dans Jane Eyre sont perpétués et subvertis à travers Rebecca en tant que texte moderne – et d’identifier et d’étudier les perceptions masculines victoriennes et néo-victoriennes.

    1977-01-01

    A method is proposed to streamline the transform decoding algorithm for Reed-Solomon (RS) codes of length equal to 2 raised to the power 2n. It is shown that a high-radix fast Fourier transform (FFT) type algorithm with generator equal to 3 on GF(F sub n), where F sub n is a Fermat prime, can be used to decode RS codes of this length. For a 256-symbol RS code, a radix 4 and radix 16 FFT over GF(F sub 3) require, respectively, 30 and 70% fewer modulo F sub n multiplications than the usual radix 2 FFT.

    An analytical procedure was developed to simultaneously determine bisphenol S, bisphenol F, bisphenol B, bisphenol A, bisphenol AF, tetrachlorobisphenol A, and tetrabromobisphenol A in reed and Callitrichaceae. Homogenized samples were extracted with acetonitrile and purified using an ENVI™-Carb cartridge followed by an NH2 cartridge. The analytes were separated and quantified by ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The recoveries at three fortified levels in reed and Callitrichaceae were 57-108% and 68-106%, respectively, with relative standard deviations of no more than 15% (n=6). The method limits of quantification and detection for the seven bisphenol analogues were 0.005-0.500μg/kg and 0.002-0.150μg/kg, respectively. This method was used to analyze the seven compounds in ten reed and Callitrichaceae samples collected from Zhejiang, China. Copyright © 2014 Elsevier B.V. All rights reserved.

  14. Coping with shifting nest predation refuges by European reed Warblers Acrocephalus scirpaceus.

    Directory of Open Access Journals (Sweden)

    Lucyna Halupka

    Full Text Available Predation, the most important source of nest mortality in altricial birds, has been a subject of numerous studies during past decades. However, the temporal dynamics between changing predation pressures and parental responses remain poorly understood. We analysed characteristics of 524 nests of European reed warblers monitored during six consecutive breeding seasons in the same area, and found some support for the shifting nest predation refuge hypothesis. Nest site characteristics were correlated with nest fate, but a nest with the same nest-site attributes could be relatively safe in one season and vulnerable to predation in another. Thus nest predation refuges were ephemeral and there was no between-season consistency in nest predation patterns. Reed warblers that lost their first nests in a given season did not disperse farther for the subsequent reproductive attempt, compared to successful individuals, but they introduced more changes to their second nest sites. In subsequent nests, predation risk remained constant for birds that changed nest-site characteristics, but increased for those that did not. At the between-season temporal scale, individual birds did not perform better with age in terms of reducing nest predation risk. We conclude that the experience acquired in previous years may not be useful, given that nest predation refuges are not stable.

    2018-03-01

    We design forward and backward fault-tolerant conversion circuits, which convert between the Steane code and the 15-qubit Reed-Muller quantum code so as to provide a universal transversal gate set. In our method, only seven out of a total 14 code stabilizers need to be measured, and we further enhance the circuit by simplifying some stabilizers; thus, we need only to measure eight weight-4 stabilizers for one round of forward conversion and seven weight-4 stabilizers for one round of backward conversion. For conversion, we treat random single-qubit errors and their influence on syndromes of gauge operators, and our novel single-step process enables more efficient fault-tolerant conversion between these two codes. We make our method quite general by showing how to convert between any two adjacent Reed-Muller quantum codes \\overline{\\textsf{RM}}(1,m) and \\overline{\\textsf{RM}}≤ft(1,m+1\\right) , for which we need only measure stabilizers whose number scales linearly with m rather than exponentially with m obtained in previous work. We provide the explicit mathematical expression for the necessary stabilizers and the concomitant resources required.

  16. Evaluating the Value of High Spatial Resolution in National Capacity Expansion Models using ReEDS

    Energy Technology Data Exchange (ETDEWEB)

    Krishnan, Venkat; Cole, Wesley

    2016-07-18

    This poster is based on the paper of the same name, presented at the IEEE Power & Energy Society General Meeting, July18, 2016. Power sector capacity expansion models (CEMs) have a broad range of spatial resolutions. This paper uses the Regional Energy Deployment System (ReEDS) model, a long-term national scale electric sector CEM, to evaluate the value of high spatial resolution for CEMs. ReEDS models the United States with 134 load balancing areas (BAs) and captures the variability in existing generation parameters, future technology costs, performance, and resource availability using very high spatial resolution data, especially for wind and solar modeled at 356 resource regions. In this paper we perform planning studies at three different spatial resolutions - native resolution (134 BAs), state-level, and NERC region level - and evaluate how results change under different levels of spatial aggregation in terms of renewable capacity deployment and location, associated transmission builds, and system costs. The results are used to ascertain the value of high geographically resolved models in terms of their impact on relative competitiveness among renewable energy resources.

  17. L’image du père et du jardin : Jane Eyre de Charlotte Brontë  et WideSargasso Sea de Jean Rhys Of Father Figures and Gardens: Charlotte Brontë’s Jane Eyre and Jean Rhys’s Wide Sargasso Sea

    Directory of Open Access Journals (Sweden)

    Anne-Marie Baranowski

    2009-10-01

    Full Text Available Though no father actually appears as a character either in Jane Eyre or in Wide Sargasso Sea, the father figure looms large in both novels, as a complex, protean and paradoxical entity, playing a crucial part in the fate of the protagonists. Jane Eyre and Antoinette Cosway are orphaned at an early age, Rochester’s father is depicted as remote and insensitive; the surrogate fathers —Antoinette’s stepfather, Jane’s uncles— mostly fail when they try to replace the missing one. Rochester himself is an ambiguous character who appears in both novels as a son, lover and husband on the one side, as a father figure on the other. In Wide Sargasso Sea he acquires through his marriage to the heiress Antoinette Cosway a legal authority which he eventually uses to destroy his wife; in Jane Eyre he first appears as the wealthier, more knowledgeable, stronger character before he discovers a female counterpart who does more than merely hold her ground.These different aspects of the father figure are closely linked to the motif of the garden which mirrors the inner development of the —mostly— female characters. It is not entirely similar to nature itself, though it is part of it; the latter means in both novels lethal dangers and elemental violence, whereas the garden is a sheltered place. In Wide Sargasso Sea, the debased garden of Coulibri simultaneously conveys a distorted, though by no means untrue reflection of the father figure and a sanctuary from the harshness of the outside world. It also means a place of peace and of simple joys for Jane Eyre, making up for the deprived life at the Lowood boarding school; but contrasting with Coulibri it does not preclude the contact with the outside world which she actually longs for. Hence the garden mirrors the crucial moments and experiences in the lives of both heroines, including love, married life and loss.

    2012-11-01

    The purpose of this essay is to discuss the constructions and effects of the parodic dialogue Jane Austen’s novel Northanger Abbey (1818 establishes with a tradition of Gothic literature in the eighteenth-century English context. Because it is considered as an expressive form of intertextuality, parody (both in the sense of ‘parallel song’ and ‘counter-song’ actively and creatively recodifies the tradition it parodies. As a consequence, studying such an articulation means being aware of a comparative interplay among codes, textualities, readings and literary traditions, so as to recognize the effects of parody as also articulated with a larger context of metafiction.

    The electric power system in North America is linked between the United States and Canada. Canada has historically been a net exporter of electricity to the United States. The extent to which this remains true will depend on the future evolution of power markets, technology deployment, and policies. To evaluate these and related questions, we modify the Regional Energy Deployment System (ReEDS) model to include an explicit representation of the grid-connected power system in Canada to the continental United States. ReEDS is unique among long-term capacity expansion models for its high spatial resolution and statistical treatment of the impact of variable renewable generation on capacity planning and dispatch. These unique traits are extended to new Canadian regions. We present example scenario results using the fully integrated Canada-U.S. version of ReEDS to demonstrate model capabilities. The newly developed, integrated Canada-U.S. ReEDS model can be used to analyze the dynamics of electricity transfers and other grid services between the two countries under different scenarios.

    The mixture of kura clover (Trifolium ambiguum M. Bieb.) and reed canarygrass (Phalaris arundinacea L.) has proven to be extremely persistent in the northern United States, but information about dairy cow performance on this mixture is lacking. Twenty lactating Holstein cows were used in a crossover design to compare dry matter (DM) intake and milk production from diets containing kura clover-reed canarygrass silage (KRS) or alfalfa (Medicago sativa L.) silage (AS). Forages were cut, wilted, ensiled in horizontal plastic bags, and allowed to ferment for at least 50 d before beginning the feeding experiment. The KRS was approximately 40% kura clover and 60% reed canarygrass. Treatments were total mixed rations formulated with either 57% of total DM from 1) AS or 2) KRS. Experimental periods were 28 d, with the first 14 d for diet adaptation and the last 14 d for measurement of intake and milk production. The neutral detergent fiber (NDF) concentrations of AS and KRS were 37.3 and 47.3%, respectively. The fermentation analyses indicated that both silages underwent a restricted fermentation, producing primarily lactic acid and some acetic acid. Dry matter intake (24.2 vs. 22.8 kg) and 4% fat-corrected milk (32.8 vs. 30.9 kg) were significantly higher for cows fed AS than for cows fed KRS. Cows consumed less NDF (6.7 vs. 8.0 kg) and less digestible NDF (3.0 vs. 4.4 kg) when fed AS diets compared with KRS diets, but the pool of ruminally undegraded NDF was similar (3.7 kg) between diets. Cows produced 1.5 kg of milk/kg of DM consumed regardless of the diet, indicating that digestible NDF of KRS was utilized with similar efficiency as the cell wall constituents of AS, but the intake of cows fed KRS may have been limited by rumen fill. Milk fat concentration tended to be higher for cows fed AS, but the milk true protein concentration and yields of fat and protein did not differ by treatment. Milk urea nitrogen content was higher when cows consumed AS (16.4 mg/ d

    Full Text Available Aquatic reed is an important indicator for the ecological assessment of freshwater lakes. Monitoring is essential to document its expansion or deterioration and decline. The applicability of Green-LiDAR data for the status assessment of aquatic reed beds of Bavarian freshwater lakes was investigated. The study focused on mapping diagnostic structural parameters of aquatic reed beds by exploring 3D data provided by the Green-LiDAR system. Field observations were conducted over 14 different areas of interest along 152 cross-sections. The data indicated the morphologic and phenologic traits of aquatic reed, which were used for validation purposes. For the automatic classification of aquatic reed bed spatial extent, density and height, a rule-based algorithm was developed. LiDAR data allowed for the delimitating of the aquatic reed frontline, as well as shoreline, and therefore an accurate quantification of extents (Hausdorff distance = 5.74 m and RMSE of cross-sections length 0.69 m. The overall accuracy measured for aquatic reed bed density compared to the simultaneously recorded aerial imagery was 96% with a Kappa coefficient of 0.91 and 72% (Kappa = 0.5 compared to field measurements. Digital Surface Models (DSM, calculated from point clouds, similarly showed a high level of agreement in derived heights of flat surfaces (RMSE = 0.1 m and showed an adequate agreement of aquatic reed heights with evenly distributed errors (RMSE = 0.8 m. Compared to field measurements, aerial laser scanning delivered valuable information with no disturbance of the habitat. Analysing data with our classification procedure improved the efficiency, reproducibility, and accuracy of the quantification and monitoring of aquatic reed beds.

    Full Text Available Este trabalho tem como objetivo analisar as estratégias de resistência dos subalternos em Jane Eyre (2008, romance de Charlotte Brontë publicado originalmente em 1847, a partir de uma interpretação pós-colonialista. As personagens enfatizadas serão as oriundas da Jamaica, Bertha Mason e seu irmão, Richard, utilizando os modelos de resistência que Ascroft, Griffiths e Tiffin (2010 definem como ab-rogação e apropriação e as que Bhabha (2010 menciona como sly civility (cortesia dissimulada e mímica. Bertha Mason, a principal representante da subalternidade, faz mais uso da sly civility e da ab-rogação, enquanto Richard Mason utiliza-se mais da mímica e da apropriação, isso porque a colonizada repudia a cultura do centro, ao negar a linguagem europeia, diferentemente do irmão, que procura a imitação, ao apropriar-se do discurso do europeu para garantir seu lugar social, e, desse modo, o hibridismo cultural. Considerada louca e não tendo voz no romance, Bertha Mason desperta a nossa curiosidade acerca da honestidade da narradora, por esta ser branca e seu discurso ser construído a partir de discursos de personagens também brancos, principalmente o de Rochester cujo casamento com a autóctone fora considerado uma empreitada colonial. Dessa forma, somos motivados a compreender a exclusão dos subalternos do mundo simbólico, em correlação com sua procedência racial, cultural e mental, extraindo disso a possibilidade de as cesuras discursivas simbolizarem a opressão e repressão coloniais de uma assujeitação violenta. No entanto, isso não atesta a anulação do sujeito subalterno, pois mesmo censurado, discursivamente, encontra alternativas para resistir às forças colonizadoras.

  6. Jane Austen's lifelong health problems and final illness: New evidence points to a fatal Hodgkin's disease and excludes the widely accepted Addison's.

    Science.gov (United States)

    Upfal, A

    2005-06-01

    Jane Austen is typically described as having excellent health until the age of 40 and the onset of a mysterious and fatal illness, initially identified by Sir Zachary Cope in 1964 as Addison's disease. Her biographers, deceived both by Cassandra Austen's destruction of letters containing medical detail, and the cheerful high spirits of the existing letters, have seriously underestimated the extent to which illness affected Austen's life. A medical history reveals that she was particularly susceptible to infection, and suffered unusually severe infective illnesses, as well as a chronic conjunctivitis that impeded her ability to write. There is evidence that Austen was already suffering from an immune deficiency and fatal lymphoma in January 1813, when her second and most popular novel, Pride and Prejudice, was published. Four more novels would follow, written or revised in the shadow of her increasing illness and debility. Whilst it is impossible now to conclusively establish the cause of her death, the existing medical evidence tends to exclude Addison's disease, and suggests there is a high possibility that Jane Austen's fatal illness was Hodgkin's disease, a form of lymphoma.

  7. RAID-6 reed-solomon codes with asymptotically optimal arithmetic complexities

    KAUST Repository

    Lin, Sian-Jheng

    2016-12-24

    In computer storage, RAID 6 is a level of RAID that can tolerate two failed drives. When RAID-6 is implemented by Reed-Solomon (RS) codes, the penalty of the writing performance is on the field multiplications in the second parity. In this paper, we present a configuration of the factors of the second-parity formula, such that the arithmetic complexity can reach the optimal complexity bound when the code length approaches infinity. In the proposed approach, the intermediate data used for the first parity is also utilized to calculate the second parity. To the best of our knowledge, this is the first approach supporting the RAID-6 RS codes to approach the optimal arithmetic complexity.

    Phytoplankton gross primary production ( 14 C method) in the shallow, eutrophic Danish Lake Arresoe in 1973 was 980 g C m -2 . Calculated net primary production was near zero. Macrophyte net primary production was measured by harvesting the maximum biomass, and above ground values were between 420 and 1325 g ash free dry wt m -2 , while below ground values were between 2480 and 8570 g ash free dry wt m -2 . The reed swamps were mapped on aerial photographs, and the composition of the macrophyte vegetation was determined. A comparison of macrophyte vegetation in 1944 and 1972 showed a reduction in species diversity, especially of submerged species. The seasonal variations in physical and chemical data indicated strong eutrophication in Arresoe. (author)

    Nd 2 Fe 14 B single crystals with magnetic moments ranging from 1.6 x 10 -8 Acm 2 to 9.5 x 10 -7 Acm 2 are measured using the ultra high sensitivity vibrating reed magnetometer. The hysteresis loops are compared to those of BaFe 12 O 19 single crystals. It turns out that the magnetization reversal of the Nd 2 Fe 14 B samples is similar to that of BaFe 12 O 19 single crystals if the ferrite samples are considerably bigger in size. This does not hold for bigger Nd 2 Fe 14 B particles where stronger domain wall pinning is observed. For very small grains of Nd 2 Fe 14 B there is still evidence of domain wall processes while for BaFe 12 O 19 grains of the same size true single domain behaviour can be observed

    Cultivation of bioenergy crops in rewetted peatland (paludiculture) is considered as a possible land use option to mitigate greenhouse gas (GHG) emissions. However, bioenergy crops like reed canary grass (RCG) can have a complex influence on GHG fluxes. Here we determined the effect of RCG...... and bare soil were measured at weekly to fortnightly intervals with static chamber techniques for a period of 1 year. Cultivation of RCG increased both ER and CH4 emissions, but decreased the N2O emissions. The presence of RCG gave rise to 69, 75 and 85% of total ER at −20, −10 and 0 cm GWL, respectively...... from ER were obviously the dominant RCG-derived GHG flux, but above-ground biomass yields, and preliminary measurements of gross photosynthetic production, showed that ER could be more than balanced due to the photosynthetic uptake of CO2 by RCG. Our results support that RCG cultivation could be a good...

  13. Novel Polynomial Basis with Fast Fourier Transform and Its Application to Reed-Solomon Erasure Codes

    KAUST Repository

    Lin, Sian-Jheng

    2016-09-13

    In this paper, we present a fast Fourier transform (FFT) algorithm over extension binary fields, where the polynomial is represented in a non-standard basis. The proposed Fourier-like transform requires O(h lg(h)) field operations, where h is the number of evaluation points. Based on the proposed Fourier-like algorithm, we then develop the encoding/ decoding algorithms for (n = 2m; k) Reed-Solomon erasure codes. The proposed encoding/erasure decoding algorithm requires O(n lg(n)), in both additive and multiplicative complexities. As the complexity leading factor is small, the proposed algorithms are advantageous in practical applications. Finally, the approaches to convert the basis between the monomial basis and the new basis are proposed.

  14. Contrasting results from GWAS and QTL mapping on wing length in great reed warblers.

    A major goal in evolutionary biology is to understand the genetic basis of adaptive traits. In migratory birds, wing morphology is such a trait. Our previous work on the great reed warbler (Acrocephalus arundinaceus) shows that wing length is highly heritable and under sexually antagonistic selection. Moreover, a quantitative trait locus (QTL) mapping analysis detected a pronounced QTL for wing length on chromosome 2, suggesting that wing morphology is partly controlled by genes with large effects. Here, we re-evaluate the genetic basis of wing length in great reed warblers using a genomewide association study (GWAS) approach based on restriction site-associated DNA sequencing (RADseq) data. We use GWAS models that account for relatedness between individuals and include covariates (sex, age and tarsus length). The resulting association landscape was flat with no peaks on chromosome 2 or elsewhere, which is in line with expectations for polygenic traits. Analysis of the distribution of p-values did not reveal biases, and the inflation factor was low. Effect sizes were however not uniformly distributed on some chromosomes, and the Z chromosome had weaker associations than autosomes. The level of linkage disequilibrium (LD) in the population decayed to background levels within c. 1 kbp. There could be several reasons to why our QTL study and GWAS gave contrasting results including differences in how associations are modelled (cosegregation in pedigree vs. LD associations), how covariates are accounted for in the models, type of marker used (multi- vs. biallelic), difference in power or a combination of these. Our study highlights that the genetic architecture even of highly heritable traits is difficult to characterize in wild populations. © 2018 John Wiley & Sons Ltd.

    The application of municipal sewage sludge on energy crops is an alternative form of recycling nutrients, food materials, and organic matter from waste. Municipal sewage sludge constitutes a potential source of heavy metals in soil, which can be partially removed by the cultivation of energy crops. The aim of the research was to assess the effect of municipal sewage sludge on the uptake of heavy metals by monocotyledonous energy crops. Sewage sludge was applied at doses of 0, 10, 20, 40, and 60 Mg DM · ha(-1) once, before the sowing of plants. In a 6-year field experiment, the effect of four levels of fertilisation with sewage sludge on the uptake of heavy metals by two species of energy crops, reed canary grass (Phalaris arundinacea L.) of 'Bamse' cultivar and giant miscanthus (Miscanthus × giganteus GREEF et DEU), was analysed. It was established that the increasing doses of sewage sludge had a considerable effect on the increase in biomass yield from the tested plants. Due to the increasing doses of sewage sludge, a significant increase in heavy metals content in the energy crops was recorded. The heavy metal uptake with the miscanthus yield was the highest at a dose of 20 Mg DM · ha(-1), and at a dose of 40 Mg DM · ha(-1) in the case of reed canary grass. Research results indicate that on account of higher yields, higher bioaccumulation, and higher heavy metal uptake, miscanthus can be selected for the remediation of sewage sludge.

    Tissue culture methods offer the potential for large-scale propagation of giant reed (Arundo donax L.), a promising crop for energy biomass. In previous trials, giant reed resulted particularly suitable to in vitro culture. In this paper, with the final goal of enhancing the efficiency of in vitro production process and reducing costs, the influence of four different culture media (agar or gellan-gum solidified medium, liquid medium into a temporary immersion system-RITA ® or in a stationary state) on in vitro shoot proliferation of giant reed was evaluated. Giant reed exhibited a particular sensitivity to gelling agents during the phase of secondary shoot formation. Gellan gum, as compared to agar, improved the efficiency of in vitro culture giving more shoots with higher mean fresh and dry weight. Moreover, the cultivation of this species into a liquid medium under temporary immersion conditions or in a stationary state, was comparatively as effective as and cheaper than that into a gellan gum medium. Increasing 6-benzylaminopurine (BA) up to 4 mg l −1 also resulted in a further enhancement of secondary shoot proliferation. The good adaptability of this species to liquid medium and the high multiplication rates observed indicate the possibility to obtain from a single node at least 1200 plantlets every six multiplication cycles (about 6 months), a number 100 fold higher than that obtained yearly per plant by the conventional methods of vegetative multiplication. In open field, micropropagated plantlets guaranteed a higher number of survived plants, secondary stems and above ground biomass as compared to rhizome ones. - Highlights: • In vitro propagation offers the potential for large-scale propagation of giant reed. • The success of an in vitro protocol depends on the rate and mode of shoot proliferation. • Substituting liquid media to solid ones may decrease propagation costs in Arundo donax. • Giant reed showed good proliferation rates in

  2. Reed beds may facilitate transfer of tributyltin from aquatic to terrestrial ecosystems through insect vectors in the Archipelago Sea, SW Finland.

    Due to their adsorptive behavior, organotin compounds (OTCs), such as tributyltin (TBT), are accumulated in aquatic sediments. They resist biodegradation and, despite a ban in 2008, are a potential source for future exposure. Sediment OTCs have mostly been measured from sites of known high concentrations such as ports, shipping lanes, and marine dredging waste sites. The possible flow of OTCs from marine to terrestrial ecosystems, however, has not been studied. In the present study, the authors assessed whether sediments in common reed beds (Phragmites australis) accumulate TBT and whether chironomid (Diptera: Chironomidae) communities developing in reed-bed sediments act as vectors in the transfer of TBT from aquatic to terrestrial ecosystems in the Airisto channel, Archipelago Sea. The authors also investigated whether distance from the only known source and depth and TBT concentration of the adjacent shipping lane affect reed-bed concentrations. Thirty-six sites along the Airisto channel were sampled at 2-km intervals with triplicate samples from reed beds and the adjacent shipping lane for sediment and seven reed-bed sites for chironomids, and these were analyzed with an solid phase extraction liquid chromatography tamdem mass spectrometry method. The closer to the source the sample site was, the higher the measured TBT concentrations were; and the deeper the shipping lane, the lower the concentration of TBT in reed-bed sediments. The chironomid TBT concentrations correlated with reed-bed sediment TBT concentrations and showed evidence of accumulation. Therefore, TBT may be transferred, through the food web, from aquatic to terrestrial ecosystems relatively close to a source through ecosystem boundaries, such as common reed beds, which are areas of high insect biomass production in the Archipelago Sea.

    2016-07-01

    Power sector capacity expansion models (CEMs) have a broad range of spatial resolutions. This paper uses the Regional Energy Deployment System (ReEDS) model, a long-term national scale electric sector CEM, to evaluate the value of high spatial resolution for CEMs. ReEDS models the United States with 134 load balancing areas (BAs) and captures the variability in existing generation parameters, future technology costs, performance, and resource availability using very high spatial resolution data, especially for wind and solar modeled at 356 resource regions. In this paper we perform planning studies at three different spatial resolutions--native resolution (134 BAs), state-level, and NERC region level--and evaluate how results change under different levels of spatial aggregation in terms of renewable capacity deployment and location, associated transmission builds, and system costs. The results are used to ascertain the value of high geographically resolved models in terms of their impact on relative competitiveness among renewable energy resources.

C: Sewage sludge application before sowing (establishment year) and recommended amounts of P and K and half amount of N. The biomass was lower where reed canary grass had been undersown in barley, and higher with full N-fertilization than with half N-fertilization. However there were no significant differences between legume intercrops with half N-fertilization and pure reed canary grass with full Nfertilization. Alsike clover was the most productive legume, followed by red clover. The amount of nitrogen fixed by the legumes was less with full N-fertilization (29 kg/ha as a mean) than with half N-fertilization (38 kg/ha). Intercropping with legumes could substitute half of the N in fertilization but similar experiments in other parts of Sweden has shown that there is a higher risk of weed problems

    In his research, we have proposed the (64, 40, 8) subcode of the third-order Reed-Muller (RM) code to NASA for high-speed satellite communications. This RM subcode can be used either alone or as an inner code of a concatenated coding system with the NASA standard (255, 233, 33) Reed-Solomon (RS) code as the outer code to achieve high performance (or low bit-error rate) with reduced decoding complexity. It can also be used as a component code in a multilevel bandwidth efficient coded modulation system to achieve reliable bandwidth efficient data transmission. This report will summarize the key progress we have made toward achieving our eventual goal of implementing a decoder system based upon this code. In the first phase of study, we investigated the complexities of various sectionalized trellis diagrams for the proposed (64, 40, 8) RNI subcode. We found a specific 8-trellis diagram for this code which requires the least decoding complexity with a high possibility of achieving a decoding speed of 600 M bits per second (Mbps). The combination of a large number of states and a hi ch data rate will be made possible due to the utilization of a high degree of parallelism throughout the architecture. This trellis diagram will be presented and briefly described. In the second phase of study which was carried out through the past year, we investigated circuit architectures to determine the feasibility of VLSI implementation of a high-speed Viterbi decoder based on this 8-section trellis diagram. We began to examine specific design and implementation approaches to implement a fully custom integrated circuit (IC) which will be a key building block for a decoder system implementation. The key results will be presented in this report. This report will be divided into three primary sections. First, we will briefly describe the system block diagram in which the proposed decoder is assumed to be operating and present some of the key architectural approaches being used to

    Malaria parasites often manage to maintain an infection for several months or years in their vertebrate hosts. In humans, rodents and birds, most of the fitness costs associated with malaria infections are in the short initial primary (high parasitaemia) phase of the infection, whereas the chronic phase (low parasitaemia) is more benign to the host. In wild birds, malaria parasites have mainly been studied during the chronic phase of the infection. This is because the initial primary phase of infection is short in duration and infected birds with severe disease symptoms tend to hide in sheltered places and are thus rarely caught and sampled. We therefore wanted to investigate the relationship between the parasitaemia during the primary and chronic phases of the infection using an experimental infection approach. We found a significant positive correlation between parasitaemia in the primary peak and the subsequent chronic phase of infection when we experimentally infected great reed warblers (Acrocephalus arundinaceus) with Plasmodium ashfordi. The reason for this association remains to be understood, but might arise from individual variation in exoerythrocytic parasite reservoirs in hosts, parasite antigenic diversity and/or host genetics. Our results suggest that the chronic phase parasitaemia can be used to qualitatively infer the parasitaemia of the preceding and more severe primary phase, which is a very important finding for studies of avian malaria in wild populations.

    Full Text Available There has been renewed interest in decoding Reed-Solomon (RS codes without using syndromes recently. In this paper, we investigate the complexity of syndromeless decoding, and compare it to that of syndrome-based decoding. Aiming to provide guidelines to practical applications, our complexity analysis focuses on RS codes over characteristic-2 fields, for which some multiplicative FFT techniques are not applicable. Due to moderate block lengths of RS codes in practice, our analysis is complete, without big O notation. In addition to fast implementation using additive FFT techniques, we also consider direct implementation, which is still relevant for RS codes with moderate lengths. For high-rate RS codes, when compared to syndrome-based decoding algorithms, not only syndromeless decoding algorithms require more field operations regardless of implementation, but also decoder architectures based on their direct implementations have higher hardware costs and lower throughput. We also derive tighter bounds on the complexities of fast polynomial multiplications based on Cantor's approach and the fast extended Euclidean algorithm.

    Treatment of sludge in sludge treatment reed bed systems includes dewatering and mineralization. The mineralization process, which is driven by microorganisms, produces different gas species as by-products. The pore space composition of the gas species provides useful information on the biological processes occurring in the sludge residue. In this study, we measured the change in composition of gas species in the pore space at different depth levels in vertical sludge residue profiles during a resting period of 32 days. The gas composition of the pore space in the sludge residue changed during the resting period. As the resting period proceeded, atmospheric air re-entered the pore space at all depth levels. The methane (CH 4 ) concentration was at its highest during the first part of the resting period, and then declined as the sludge residue became more dewatered and thereby aerated. In the pore space, the concentration of CH 4 often exceeded the concentration of carbon dioxide (CO 2 ). However, the total emission of CO 2 from the surface of the sludge residue exceeded the total emission of CH 4 , suggesting that CO 2 was mainly produced in the layer of newly applied sludge and/or that CO 2 was emitted from the sludge residue more readily compared to CH 4 .

  12. Structural and mechanical design of tissue interfaces in the giant reed Arundo donax.

    The culms of the giant reed Arundo donax represent slender tube-like structures. Several nodes along the culm, a ring of sclerenchymatous fibres in the periphery of the culm wall and numerous isolated vascular bundles enclosed by fibre rings in the culm wall function as stiffening elements. The bundles are embedded in lignified parenchyma. Micromechanical analysis indicated differences in stiffness between the individual tissues of more than one order of magnitude. In case of abrupt transitions in stiffness at the interfaces, stress discontinuities arise under dynamic loads. This eventually leads to critical shear stresses at cell ends, and culm failure may be initiated at these points. Pronounced mechanical differences between individual tissues can be compromised by gradual transitions at their interfaces. Ultrastructural and spectroscopic investigations with high spatial resolution revealed a gradual transition of cell parameters (cell wall area fraction and cell length). However, cell wall parameters (cellulose microfibril angle and lignin content) showed abrupt transitions or remained almost constant across the interfaces between various tissues. The design principles found at the interfaces between tissues in the culm walls of A. donax are discussed as an adaptation strategy to mechanical loads at different levels of hierarchy.

    The purpose of this study was to provide science-based information to practitioners and managers of restoration projects in the Columbia Estuary Ecosystem Restoration Program (CEERP) regarding aspects of restoration techniques that currently pose known challenges and uncertainties. The CEERP is a program of the Bonneville Power Administration (BPA) and the U.S. Army Corps of Engineers (Corps), Portland District, in collaboration with the National Marine Fisheries Service and five estuary sponsors implementing restoration. The estuary sponsors are Columbia Land Trust, Columbia River Estuary Study Taskforce, Cowlitz Tribe, Lower Columbia Estuary Partnership, and Washington Department of Fish and Wildlife. The scope of the research conducted during federal fiscal year 2015 included three aspects of hydrologic reconnection that were selected based on available scientific information and feedback from restoration practitioners during project reviews: the design of mounds (also called hummocks, peninsulas, or berms); the control of reed canarygrass (Phalaris arundinaceae); and aspects of channel network design related to habitat connectivity for juvenile salmonids.

    1997-01-01

    The objective of this study concerns the industrial applications and economic viability of using RCG (Reed Canary Grass). The study is based on a systems and costs analysis where the cost structure in the whole production chain is assessed. This includes cultivation, harvest, transportation, fractionation, pelletizing, combustion and pump production. Moreover the study assess the environmental impact by comparing the use of pesticides and fertilizers with conventional crops. A few scenarios are selected in order to conduct further sensitivity analysis regarding price fluctuations, set aside premiums, energy taxation and variation in cost of land. In addition, the study describes the market possibilities for RCG end products in Europe. The market for short fibre pump is stable in Finland and Sweden and calculations indicate potential possibilities of using upgraded RCG on existing sulphate pulp and paper mills. The upgraded leave fraction should be used for either district heating, small scale heating or process energy at the pump mill. Furthermore, the calculations show that it is economic viable to grow RCG on marginal land with a minimum environmental impact compared with conventional crops. (au) 18 refs

    American bur-reed (Sparganium americanum Nutt.), a common aquatic plant in the middle and eastern United States and Canada, is often located in water-retaining drainage areas. The purpose of this study was to determine the leaf composition of S. americanum, paying attention to the cuticular waxes and the epidermis, and its ability to sorb pesticides. S. americanum leaves (n = 100) were collected in both early (June) and late (August) summer. Transverse sections of S. americanum were stained and studied with brightfield and fluorescence microscopy to estimate the structural and chemical nature of the leaf tissues cross sections. Mean total lipid content in early summer leaf samples (1.47 ± 0.83 mg mL -1 ) was significantly greater (alpha 0.05) than late summer leaves (0.15 ± 0.36 mg mL -1 ). In vitro analysis of epidermal peel permeability exposed to atrazine and malathion determined little to no sorption by the plant. Therefore, the structure of S. americanum leaves suggest this species does not have the capacity of sorbing these pesticides from runoff water.

    The ability of aculeate Hymenoptera to utilize wetlands is poorly understood, and descriptions of their nests and developmental stages are largely absent. Here we present results based on our survey of hymenopterans using galls induced by Lipara spp. flies on common reed Phragmites australis in the years 2015-2016. We studied 20,704 galls, of which 9,446 were longitudinally cut and the brood from them reared in the laboratory, while the remaining 11,258 galls reared in rearing bags also in laboratory conditions. We recorded eight species that were previously not known to nest in reed galls: cuckoo wasps Chrysis rutilans and Trichrysis pumilionis, solitary wasps Stenodynerus chevrieranus and Stenodynerus clypeopictus, and bees Pseudoanthidium tenellum, Stelis punctulatissima, Hylaeus communis and Hylaeus confusus. Forty five species of Hymenoptera: Aculeata are known to be associated with reed galls, of which 36 make their nests there, and the other are six parasitoids of the family Chrysididae and three cuckoo bees of the genus Stelis. Of these species, Pemphredon fabricii and in southern Europe also Heriades rubicola are very common in reed galls, followed by Hylaeus pectoralis and two species of the genus Trypoxylon. We also found new host-parasite associations: Chrysis angustula in nests of Pemphredon fabricii, Chrysis rutilans in nests of Stenodynerus clypeopictus, Trichrysis pumilionis in nests of Trypoxylon deceptorium, and Stelis breviuscula in nests of Heriades rubicola. We provide new descriptions of the nests of seven species nesting in reed galls and morphology of mature larvae of eight species nesting in reed galls and two parasitoids and one nest cleptoparasite. The larvae are usually very similar to those of related species but possess characteristics that make them easy to distinguish from related species. Our results show that common reeds are not only expansive and harmful, but very important for many insect species associated with habitats

    The superhydrophobicities and the contact time of lotus leaf and reed leaf were investigated. The results indicated that both lotus leaf and reed leaf have good superhydrophobic properties, and the water contact time was 12.7 and 14.7 ms on the surface of lotus leaf and reed leaf, respectively. Surface structure plays a key role in the different contacting times. Homogeneous distribution of papillae on the surface of lotus leaf was more helpful to reduce the contact time than anisotropic groove-shape on the surface of reed leaf. Based on the bionics coupling theory, the bionics sample possessing similar lotus-leaf-like surface structure on the aluminum alloy was designed and fabricated successfully. The water contact angle was about 153 ± 2°, sliding angle less than 5°, and the water contact time was 13.4 ms on the surface of bionics sample, which presented excellent superhydrophobic property, and achieved the aim of bionic design.

    In this study, the removal of arsenic (As) by plant, Ludwigia octovalvis, in a pilot reed bed was optimized. A Box-Behnken design was employed including a comparative analysis of both Response Surface Methodology (RSM) and an Artificial Neural Network (ANN) for the prediction of maximum arsenic removal. The predicted optimum condition using the desirability function of both models was 39 mg kg -1 for the arsenic concentration in soil, an elapsed time of 42 days (the sampling day) and an aeration rate of 0.22 L/min, with the predicted values of arsenic removal by RSM and ANN being 72.6% and 71.4%, respectively. The validation of the predicted optimum point showed an actual arsenic removal of 70.6%. This was achieved with the deviation between the validation value and the predicted values being within 3.49% (RSM) and 1.87% (ANN). The performance evaluation of the RSM and ANN models showed that ANN performs better than RSM with a higher R 2 (0.97) close to 1.0 and very small Average Absolute Deviation (AAD) (0.02) and Root Mean Square Error (RMSE) (0.004) values close to zero. Both models were appropriate for the optimization of arsenic removal with ANN demonstrating significantly higher predictive and fitting ability than RSM.

    Maternal investment can play an important role for offspring fitness, especially in birds, as females have to provide their eggs with all the necessary nutrients for the development of the embryo. It is known that this type of maternal investment can be influenced by the quality of the male partner. In this study, we first verify that male song is important in the mate choice of female Eurasian reed warblers, as males mate faster when their singing is more complex. Furthermore, female egg inv...

    An ammonia-oxidizing bacterium (strain YNSRA) was isolated from the rhizoplane of the reed (Phragmites communis) used in an aquaponics plant which is a wastewater treatment plant. Strain YNSRA was identified as Nitrosomonas communis by taxonomic studies. The hydroxylamine-cytochrome c reductase (HCR) of strain YNSRA was found to have a higher activity (25.60 u/mg) than that of Nitrosomonas europaea ATCC25978T (8.94 u/mg). Ribulose-1,5-bisphosphate carboxylase (RubisCO) activity was detected at very low levels in strain YNSRA, whereas strain ATCC25978T had definite activity.

    Full Text Available The last decades has seen a proliferation of Jane Austen’s novels for television and cinema. Despite being an important movement for the popularity of her literary work that has also brought some problems for a serious understanding of Austen’s literary project. The purpose of this essay is to point out the need of considering the changes, preferences and omissions, apparently not very important or carried out because of some demands of the translation from a novel to the cinema, that occur when her work is revisited. We will try to show some choices made in the transference from her novels to film may erase part of the writer’s fictional project which is among other things to portray women’s role in the nineteenth century patriarchal English society and try to change women’s condition of invisibility that had been created and spread since Enlightenment. In order to illustrate our point the 2005 version of Pride and Prejudice for the cinema will be used.

    Full Text Available Since its publication in 1814, Jane Austen’s most famous novel, Pride and Prejudice, has enjoyed great success and has been the object of countless re-workings, re-mediations and adaptations on global scale. This essay aims at discussing a special instance of this phenomenon: an Italian re-make entitled Pregiudizio e Orgoglio (2012 and written by Austen enthusiast and admirer, P. R. Moore-Dewey (pseudonym of Patrizia Murreddu. I intend to analyze the change of perspective adopted by the author, who decided to re-write Austen's tale through the point of view of Mr. Darcy and his sister Georgiana. Moreover, it is my intention to look at some of the many intertextual references present in Moore-Dewey’s work and consider the impact of such references and quotations on the reading experience. Finally, I will consider the extensive use of paratextual devices, which contribute to define this work a particularly relevant literary manifestation.

    Full Text Available Jane Eyre is a novel written in the early nineteenth century (1847. It depicts the English society of the upper, middle and lower class and their habits and attitudes towards life. The opening of the novel points to social class, wealth and marriage as its major theme. Throughout the novel, the relationship between social awareness of class and marriage, especially dealing with money or property are highlighted, the reason why society tends to consider about social class, money and property in finding a suitable partner to marry. This paper relies on the examples from the novel to show how nineteenth-century women imagined their marriage. In terms of women’s social rights and roles, Charlotte Bronte tries to open readers' eyes to the idea that women's abilities should not be limited only to the sphere of the family. Bronte’s novel does not only attack Victorian class structure but also the issue of gender.   Keywords : marriage, wealth, property, women’s roles, gender

    ReedHycalog, a division of National Oilwell Varco Inc., is advancing its drill bit technology and is setting performance records in an effort to meet the needs of drillers in western Canada. This article described the company's new drill bit technology. Through its motor series polycrystalline diamond cutter (PDC) bits, ReedHycalog developed and commercialized several unique and proprietary drill bit features that reduced variations in torque. This lowered the risk of stick-slip while improving lateral stability, directional control and drilling efficiency. The design of the motor series bits was reviewed along with laboratory and field testing. Smooth torque was identified as one of the greatest challenges when drilling with a drill bit on a directional assembly. Test results revealed that there are 4 distinct characteristics for optimal steerable motor performance, such as smooth torque control components (TCC) that were specifically positioned in the cone of the bit to prevent cutter over engagement reducing in torque fluctuations for optimal tool face control; optimized cutter backrakes that provided high penetration rates in rotating mode, while TCCs were optimized to control torque when sliding; gauge inserts for lateral control that provided a low-friction bearing surface; and laterally exposed gauge cutters that cleaned up the hole in rotating mode, and a tapered upper section that reduced gauge pad interference while in sliding mode. The motor series bits performed extremely well in the vertical, build and horizontal intervals with multiple operators. 1 ref., 3 figs.

    2009-07-01

    The aim of this preliminary study was to summarize existing information and to develop an outline plan for a mobile briquette plant based on the conditions and requirements of reed canary grass production on forestry land. The results of the study show that there is potential to build up small-scale briquette production from reed canary grass in the areas around Arvidsjaur, Lycksele and Malaa. Important conclusions from the study are that there are potential users for reed canary grass briquettes in all three areas studied, but that profitability for mobile briquette plants is dependent on the willingness of the users to pay well for the briquettes. These briquette plants would need a relatively high degree of automation for commercial operation to be profitable. The first plant should therefore be collocated with another business so that staff, machinery (e.g. loader) and storage space can be shared with other operations. One appropriate location would be to build up activities for a mobile reed canary grass briquette plant around Glommers Miljoeenergi's pellet plant in Glommerstraesk. Thus, the plant could be used as a demonstration mobile unit, with a stationary 'home production base'CO{sub 2} Glommerstraesk

    Full Text Available Teknik modulasi multilevel seperti M-ary Quadrature Amplitude Modulation (M-QAM memiliki kelemahan yaitu semakin tinggi level modulasi yang digunakan, maka semakin tinggi pula nilai BER yang dihasilkan. Hal ini menyebabkan kinerja sistem menjadi tidak maksimal karena sistem semakin tidak tahan terhadap noise.  Salah satu teknik error control coding yang digunakan untuk mendeteksi kesalahan sekaligus memperbaiki kesalahan yaitu kode Reed Solomon. Kelebihan dari kode Reed Solomon adalah sifatnya yang non-binary artinya data diolah dalam simbol sehingga kemampuan koreksi data lebih banyak. WARP merupakan salah satu jenis dari teknologi SDR yang bisa diprogram untuk membuat prototype sistem komunikasi nirkabel. Pengimplementasian encoder dan decoder reed solomon dengan menggunakan perangkat WARP bertujuan untuk membandingkan modulasi M-QAM dengan dan tanpa kode reed solomon, kemudian mengetahui kinerja code rate yang berbeda pada modulasi M-QAM, serta mengetahui pengaruh besarnya daya pancar dan jarak pada sistem komunikasi. Hasil implementasi terbaik terdapat pada sistem RS (15,9 yang mana dapat memperbaiki kesalahan di semua level modulasi karena memiliki kemampuan koreksi error ganda (t=3 dengan ukuran k yang sama. Dari hasil implementasi juga didapatkan kesimpulan bahwa nilai BER akan semakin besar terhadap bertambahnya jarak antar node untuk daya pancar tetap, ini menandakan jarak sangat mempengaruhi kualitas kinerja suatu sistem komunikasi.

    2011-08-01

    Full Text Available The importance of energy crops in displacing fossil fuels within the energy sector in Europe is growing. Among energy crops, the use of perennial rhizomatous grasses (PRGs seems promising owing to their high productivity and their nutrient recycling that occurs during senescence. In particular, nutrient requirements and biomass quality have a fundamental relevance to biomass systems efficiency. The objective of our study was to compare giant reed (Arundo donax L. and miscanthus (Miscanthus × giganteus Greef et Deuter in terms of nutrient requirements and cellulose, hemicelluloses and lignin content. This aim was to identify, in the Mediterranean environment, the optimal harvest time that may combine, beside a high biomass yield, high nutrient use efficiency and a good biomass quality for second generation biofuel production. The research was carried out in 2009, in San Piero a Grado, Pisa (Central Italy; latitude 43°41’ N, longitude 10°21’ E, on seven-year-old crops in a loam soil characterised by good water availability. Maximum above-ground nutrient contents were generally found in summer. Subsequently, a decrease was recorded; this suggested a nutrient remobilisation from above-ground biomass to rhizomes. In addition, miscanthus showed the highest N, P, and K use efficiency, probably related to its higher yield and its C4 pathway. Regarding biomass quality, stable values of cellulose (38%, hemicelluloses (25% and lignin (8% were reported from July onwards in both crops. Hence, these components appear not to be discriminative parameters in the choice of the harvest time in the Mediterranean environment. In conclusion, our results highlighted that, in our environment, a broad harvest period (from late autumn to winter seems suitable for these PRGs. However, further research is required to evaluate the role of rhizomes in nutrient storage and supply during the growing season, as well as ecological and productive performances in marginal

  12. Composition of Bacterial Assemblages in Different Components of Reed Warbler Nests and a Possible Role of Egg Incubation in Pathogen Regulation.

    Full Text Available Bacteria play a central role in animal health. Yet, little is known about the acquisition of bacteria and the extent to which bacteria are acquired from different environmental sources. For example, bird nests host diverse bacteria associated with the eggs, nestlings and nesting material, but previous research has typically focussed on only a limited number of nest components at a time. It therefore remains unknown to what extent bacteria are transmitted between these components. Using both molecular and culture techniques, we characterised nest-associated bacterial assemblages throughout the entire nesting cycle of reed warblers by sampling bacteria on eggs before and during incubation, within nestling faeces, and on the nesting material of post-breeding nests. We found that bacterial assemblages clustered by nest component. Yet some overlap existed between nest components, suggesting that bacterial transmission across components is likely to occur. Eggs and nestlings from the same nest harboured more similar bacteria than expected by chance, suggesting an influence of environment or genetics on bacterial assemblages. Bacterial loads were not lower on incubated eggs. Instead, incubation was associated with a change in the structure of assemblages, including a decrease in potentially-harmful Gram-negative bacteria. In addition we show for the first time, that incubation is associated with the complete extinction of harmful haemolytic bacteria. Overall, our study appears to be the first to demonstrate differences in bacterial assemblages between bird nest components. In addition, we highlight the complexity of nest bacterial assemblages and provide new insights into the benefits of incubation.

    The Geological Society of America's (GSA) Geologic Map of North America (Reed and others, 2005; 1:5,000,000) shows the geology of a significantly large area of the Earth, centered on North and Central America and including the submarine geology of parts of the Atlantic and Pacific Oceans. This map is now converted to a Geographic Information System (GIS) database that contains all geologic and base-map information shown on the two printed map sheets and the accompanying explanation sheet. We anticipate this map database will be revised at some unspecified time in the future, likely through the actions of a steering committee managed by the Geological Society of America (GSA) and staffed by scientists from agencies including, but not limited to, those responsible for the original map compilation (U.S. Geological Survey, Geological Survey of Canada, and Woods Hole Oceanographic Institute). Regarding the use of this product, as noted by the map's compilers: 'The Geologic Map of North America is an essential educational tool for teaching the geology of North America to university students and for the continuing education of professional geologists in North America and elsewhere. In addition, simplified maps derived from the Geologic Map of North America are useful for enlightening younger students and the general public about the geology of the continent.' With publication of this database, the preparation of any type of simplified map is made significantly easier. More important perhaps, the database provides a more accessible means to explore the map information and to compare and analyze it in conjunction with other types of information (for example, land use, soils, biology) to better understand the complex interrelations among factors that affect Earth resources, hazards, ecosystems, and climate.

    2016-01-01

    Sludge treatment reed bed (STRB) systems have been used for dewatering and mineralisation of sludge in Europe since 1988. STRB systems provide substantial environmental, economic, and operational benefits compared to mechanical sludge dewatering solutions such as belt presses and centrifuges....... They require less energy, no chemicals, reduce the sludge volume and produce bio solids with dry solid contents up to 20-40% under Danish climate conditions, depending on the sludge quality. Experience has shown that sludge treated in STRBs represents a high quality product with a low content of pathogens...... compared to conventional mechanical dewatering devices, delivering an economic break-even of about 3-5 years. This paper provides an overview of the operation and maintenance costs and environmental benefits of a typical STRB based on the experiences gained from the operation of a large number of STRBs...

    Here, I present the first comparison of the abundance of farmland birds in energy grass fields and in cereal-dominated conventionally cultivated fields (CCFs). I demonstrate that in boreal farmland, skylark (Alauda arvensis) densities were significantly lower in reed canary grass (RCG) (Phalaris arundinacea) fields than in CCFs. I found that during the early breeding season RCG fields and CCFs are equally good habitats, but over the ensuing couple of weeks RCG rapidly grows too tall and dense for field-nesting species. Consequently, RCG is an inferior habitat for skylark for laying replacement clutches (after failure of first nesting) or for a second clutch after one successful nesting. The results imply that if RCG cultivation is to be expanded, the establishment of large monocultures should be avoided in farmland landscapes; otherwise the novel habitat may affect detrimentally the seriously depleted skylark population, and probably also other field-nesting bird species with similar breeding habitats.

    Integral reactors require a fine reactivity control CEDM since the nuclear heating is used during the startup. Although a linear pulse motor type had been chosen for the SMART CEDM, a ball screw type is being considered as an alternative. A ball screw type CEDM driven by a rotary step motor has an emergency insertion system using electromagnet and also has a permanent magnet for RSPT in the upper pressure housing above the electromagnet. So it is necessary to evaluate an electromagnetic interference for reed switches in the vicinity of the electromagnet. This paper describes the design parameters for effective operation and the optimum design point was determined by analyzing the trend of the EMI characteristics

    2005-05-01

    A comparative study on TCF (totally chlorine-free) bleachability of organosolv pulps from the annual fibre crop Arundo donax L. (giant reed) was carried out using a simple three-stage peroxide bleaching sequence without oxygen pre-bleaching. ASAM (alkali-sulfite-anthraquinone-methanol), Organocell (alkali-anthraquinone-methanol) and ethanol-soda organosolv pulps were bleached and compared with kraft pulp, as a reference. The final brightness of 76-78% ISO was attained for all tested pulps. The chemical charge required to reach this level of brightness varied for different pulps (despite the equal initial content of the residual lignin) and directly related to starting brightness values. No direct correlation between brightness improvement and lignin removal during bleaching was found, indicating the influence of the specific pulp properties introduced by pulping process on bleaching chemistry. The general higher bleaching response of organosolv pulps from A. donax was noted in comparison with kraft.

  19. Phenotypic divergence among west European populations of Reed Bunting Emberiza schoeniclus: the effects of migratory and foraging behaviours.

    Directory of Open Access Journals (Sweden)

    Júlio M Neto

    Full Text Available Divergent selection and local adaptation are responsible for many phenotypic differences between populations, potentially leading to speciation through the evolution of reproductive barriers. Here we evaluated the morphometric divergence among west European populations of Reed Bunting in order to determine the extent of local adaptation relative to two important selection pressures often associated with speciation in birds: migration and diet. We show that, as expected by theory, migratory E. s. schoeniclus had longer and more pointed wings and a slightly smaller body mass than the resident subspecies, with the exception of E. s. lusitanica, which despite having rounder wings was the smallest of all subspecies. Tail length, however, did not vary according to the expectation (shorter tails in migrants probably because it is strongly correlated with wing length and might take longer to evolve. E. s. witherbyi, which feed on insects hiding inside reed stems during the winter, had a very thick, stubby bill. In contrast, northern populations, which feed on seeds, had thinner bills. Despite being much smaller, the southern E. s. lusitanica had a significantly thicker, longer bill than migratory E. s. schoeniclus, whereas birds from the UK population had significantly shorter, thinner bills. Geometric morphometric analyses revealed that the southern subspecies have a more convex culmen than E. s. schoeniclus, and E. s. lusitanica differs from the nominate subspecies in bill shape to a greater extent than in linear bill measurements, especially in males. Birds with a more convex culmen are thought to exert a greater strength at the bill tip, which is in agreement with their feeding technique. Overall, the three subspecies occurring in Western Europe differ in a variety of traits following the patterns predicted from their migratory and foraging behaviours, strongly suggesting that these birds have became locally adapted through natural selection.

    Dale Reed, a NASA engineer who worked on the original lifting-body research programs in the 1960s and 1970s, stands with a scale-model X-38 that was used in 1995 research flights, with a full-scale X-38 (80 percent of the size of a potential Crew Return Vehicle) behind him. The X-38 Crew Return Vehicle (CRV) research project is designed to develop the technology for a prototype emergency crew return vehicle, or lifeboat, for the International Space Station. The project is also intended to develop a crew return vehicle design that could be modified for other uses, such as a joint U.S. and international human spacecraft that could be launched on the French Ariane-5 Booster. The X-38 project is using available technology and off-the-shelf equipment to significantly decrease development costs. Original estimates to develop a capsule-type crew return vehicle were estimated at more than $2 billion. X-38 project officials have estimated that development costs for the X-38 concept will be approximately one quarter of the original estimate. Off-the-shelf technology is not necessarily 'old' technology. Many of the technologies being used in the X-38 project have never before been applied to a human-flight spacecraft. For example, the X-38 flight computer is commercial equipment currently used in aircraft and the flight software operating system is a commercial system already in use in many aerospace applications. The video equipment for the X-38 is existing equipment, some of which has already flown on the space shuttle for previous NASA experiments. The X-38's primary navigational equipment, the Inertial Navigation System/Global Positioning System, is a unit already in use on Navy fighters. The X-38 electromechanical actuators come from previous joint NASA, U.S. Air Force, and U.S. Navy research and development projects. Finally, an existing special coating developed by NASA will be used on the X-38 thermal tiles to make them more durable than those used on the space

    The feasibility of commercially available boilers in the interval 50 kW to 1 MW for use with reed canary grass (RCG) as fuel has been preliminary evaluated. The capacity to handle the large ash volumes generated by RCG both in terms of ash withdrawal and combustion quality was used as the main criteria. Nine boilers and two burners were identified and classified in a three-step scale from verified functioning on RCG to possible functioning with some design changes

    Full Text Available Little information is available as to the real effectiveness of the phytoextraction remediation technique, since laboratory experiments are still the most common way in which this is measured. Given this, an experiment on a cadmium-polluted soil was carried out in open field conditions in Southern Italy with the aim of assessing the growth and the phytoextraction potential of giant reed (Arundo donax L. Compost fertilisation and Trichoderma harzianum A6 inoculations were used to verify the possibility of increasing the metal uptake of the crop. Biomass yield of giant reed in the first growth season (average 12.8 Mg ha–1 was not affected by the Cd concentration in the soil and this increased significantly with compost fertilisation (13.8 Mg ha–1. Both compost fertilisation and T. harzianum inoculation increased cadmium uptake and translocation in leaves. Nitrifying bacteria was shown to be a useful tool to biomonitor soil quality. These results proved the suitability of the giant reed for assisted-phytoremedation with the use of compost fertilisation and T. harzianum.

    Giant reed, miscanthus, and switchgrass are considered prominent lignocellulosic feedstocks to obtain fermentable sugars for biofuel production. The bioconversion into sugars requires a delignifying pre-treatment step followed by hydrolysis with cellulase and other accessory enzymes like xylanase, especially in the case of alkali pre-treatments, which retain the hemicellulose fraction. Blends richer in accessory enzymes than commercial mix can be obtained growing fungi on feedstock-based substrates, thus ten selected Trichoderma isolates, including the hypercellulolytic strain Trichoderma reesei Rut-C30, were grown on giant reed, miscanthus, or switchgrass-based substrates. The produced enzymes were used to saccharify the corresponding feedstocks, compared to a commercial enzymatic mix (6 FPU/g). Feedstocks were acid (H 2 SO 4 0.2-2%, w/v) or alkali (NaOH 0.02-0.2%, w/v) pre-treated. A microplate-based approach was chosen for most of the experimental steps due to the large number of samples. The highest bioconversion was generally obtained with Trichoderma harzianum Or4/99 enzymes (78, 89, and 94% final sugar yields at 48 h for giant reed, miscanthus, and switchgrass, respectively), with significant increases compared to the commercial mix, especially with alkaline pre-treatments. The differences in bioconversion yields were only partially caused by xylanases (maximum R 2  = 0.5), indicating a role for other accessory enzymes.

    Full Text Available Agricultural producers are interested in using biomass available on farms to substitute fossil fuels for heat production. However, energy crops like reed canary grass contain high nitrogen (N, sulfur (S, potassium (K and other ash-forming elements which lead to increased emissions of gases and particulate matter (PM and ash-related operational problems (e.g., melting during combustion. To address these problematic behaviors, reed canary grass was blended with wood (50 wt% and fuel additives (3 wt% such as aluminum silicates (sewage sludge, calcium (limestone and sulfur (lignosulfonate based additives. When burned in a top-feed pellet boiler (29 kW, the four blends resulted in a 17%–29% decrease of PM concentrations compared to pure reed canary grass probably because of a reduction of K release to flue gas. Nitrogen oxides (NOx and sulfur dioxide (SO2 emissions varied according to fuel N and S contents. This explains the lower NOx and SO2 levels obtained with wood based products and the higher SO2 generation with the grass/lignosulfonate blend. The proportion of clinkers found in combustion ash was greatly lessened (27%–98% with the use of additives, except for lignosulfonate. The positive effects of some additives may allow agricultural fuels to become viable alternatives.

    Maternal investment can play an important role for offspring fitness, especially in birds, as females have to provide their eggs with all the necessary nutrients for the development of the embryo. It is known that this type of maternal investment can be influenced by the quality of the male partner. In this study, we first verify that male song is important in the mate choice of female Eurasian reed warblers, as males mate faster when their singing is more complex. Furthermore, female egg investment varies in relation to male song characteristics. Interestingly, clutch size, egg weight, or size, which can be considered as an high-cost investment, is not influenced by male song characteristics, whereas comparably low-cost investment types like investment into diverse egg components are adjusted to male song characteristics. In line with this, our results suggest that female allocation rules depend on investment type as well as song characteristics. For example, egg white lysozyme is positively correlated with male song complexity. In contrast, a negative correlation exists between-song speed and syllable repetitiveness and egg yolk weight as well as egg yolk testosterone concentration. Thus, our results suggest that female egg investment is related to male song performance in several aspects, but female investment patterns regarding various egg compounds are not simply correlated.

    Sustainable treatment and management of fecal sludge in rural areas require adapted solutions. Rustic and simple operating processes such as sludge treatment reed beds (STRB) have been increasingly considered for this purpose. The biggest full scale (2,600 m 2 of STRB) septage treatment unit in France had been built in Nègrepelisse with the final objectives of reusing treated sludge and leachates for agriculture spreading and tree irrigation, respectively. The aim of this investigation was to validate the treatment chain of this installation. The obtained field data showed firstly that the overall removal efficiencies of STRB were satisfactory and stable. Removal rates higher than 98% for chemical oxygen demand and suspended solids and a 95% for Kjeldahl nitrogen represented so far a beneficial septage treatment by STRB. The highlighted necessity of a suitable complementary leachate treatment (before tree irrigation) justified the presence of the second stage of vertical flow constructed wetland. The sludge deposit drying and mineralization efficiencies were on the right track. According to hydrotextural diagram analysis, surface deposit was however found to have high deformability probably due to the youth of the installation. An in-depth understanding of STRB system needs continuous long-term studies.

    Full Text Available We recognized a few possible complications of classical Hodgkin lymphoma therapy in a cohort of 209 patients: 8 developed a primary refractory disease (primary progression, 36 showed an early relapse and 21 showed a late relapse. Sialyl-CD15 expression in Hodgkin-Reed-Sternberg cells was significantly more positive in primary refractory Hodgkin lymphoma, which confirms our previously published findings. Bcl-2 showed a significantly lower level of expression in primary refractory disease than in the other follow-up groups. This is in contrast with a previous finding of Bcl-2, associated with a poor prognosis in primary refractory illness. Another category of variables, old age and advanced stages, was significantly different in the various complications but this finding is probably to be expected. We could not demonstrate a difference between the sequels and the control group with regard to several clinical and immunohistochemical markers. Sialyl-CD15 and Bcl-2 expression, in contrast, were confirmed as prognostic factors, mainly of tumor progression into primary refractory disease.

    Full Text Available A severe infestation of the gall midge Epicalamus phalaridis (Diptera: Cecidomyiidaeoccurred in a field of reed canary grass, Phalaris arundinacea in northern Sweden. The midge species has potential to become a serious pest on Phalaris grown for bioenergy or fibre production. Larvae of the midge feed beneath leaf sheaths and the crop lodges in late summer. Details are given on the biology of the midge. In the infested field, population densities of the midge were very high during three consecutive years. The crop was weakened and the occurrence of weeds increased. The dry matter yields declined markedly and were after three years of midge-attack about 50% of the average yield in the preceding years. The yield dropped comparatively more when the crop was harvested in the spring as opposed to harvest in late autumn and more at a nitrogen fertilisation at 100 kg compared to 200 kg N ha–1 per year. The effect of midge attack on fibre quality was studied. The fibre properties of midge-infested parts of internodes were poor, but as midge-damaged parts are brittle, they could probably be sorted out in a fractionation process. Undamaged parts of infested internodes had the same fibre properties as those from an uninfested crop.;

    Recent developments in microscopy have led to superresolution microscopy images of cells. Structured illumination microscopy was used before to reveal new details in the DNA structure and the structure of the DNA-free space in the DAPI-stained cell nuclei of the Hodgkin's lymphoma HDLM-2 cell line. This study extends this technology to primary pre-treatment classical Hodgkin's lymphoma samples of ten patients. Significant differences in both the DNA structure and the structure of the DNA-free space were detected between lymphocytes and malignant cells. Both types of structures were similar for lymphocytes of different patients. When the patients were un-blinded and grouped based on their clinical outcome, either non-relapsed or relapsed, a significant difference in the DNA structure of their Reed-Sternberg (RS) cells was found. Since, RS cells develop from mono-nucleated Hodgkin (H) cells, these data suggest distinct architectural restructuring of nuclei during RS cell formation in patients going to long-lasting remission versus relapse.

    Full Text Available The present experiment, carried out in nine production fields of reed canary grass (Phalaris arundinacea grown for energy purposes, evaluated the effect of plantation age on the occurrence and species composition of weeds. The selected plantations were divided into 3 groups that were conventionally called “young” (1–2 years old, “middle-aged” (3–5 years old, and “older” plantations (6–8 years old. Regardless of plantation age, altogether 43 species were found in the experimental fields. Moreover, 6 species were common for all the plantations and were found in them regardless of plantation age. The least species, only 18, were found on the “young” plantations, almost twice more on the “older” ones (30 species, whereas the largest spectrum of species was found in the “middle-aged” plantations (33 species. In the “young” plantations, annual weeds were the most common, with the highest constancy and coverage index found for Chenopodium album, Matricaria maritima ssp. inodora and Echinochloa crus-galli. The greatest variation in species was found in the “middle-aged” plantations. However, only 4 species achieved the highest constancy and coverage index: Matricaria maritima ssp. inodora, Cirsium arvense, Poa trivialis and Taraxacum officinale. Furthermore, perennial weeds were found to be dominant in the “older” plantations. Within this group, Poa trivialis, Taraxacum officinale, Urtica dioica, Plantago maior, and Cirsium arvense had the highest constancy and coverage index.

    In 19th century in Britain, there are many colliding mutually social ideas, one of which is Mill's utilitarianism. Mill holds the view that happiness is the only worth preserving aim. Jane Eyre's marital and religious ethics are consistent with Mill's utilitarianism. She protests against regarding ben-efit as only aim, sacrificing dignity and freedom to get happiness, and utilizing others and being utilized by others. Jane Eyre's ethics are due to British society's attaching importance to reason and utility, and Charlotte's laying emphasis on virtue cultivation. Jane Eyre utilitarianism not only changes the female's dependence on the male, humans' humble position to God, but also exposes the male's humanity. It seems that Charlotte points out a way of pursuing existence, development and gaining happiness for the women from low and middle class.%十九世纪的英国,各种思潮涌动,穆勒的功利主义主张幸福是唯一值得欲求的目的。简·爱在婚姻和宗教上的伦理观契合了穆勒的功利主义,并反对以利益为唯一追求目标的“功利观”,反对牺牲尊严、自由、人格完整来获取幸福,也反对利用他人和被他人利用。简·爱式的功利主义婚姻观和宗教观既是十九世纪英国社会重理性、重“实用”的产物,也是夏洛特重视伦理道德修养的产物。这种功利主义伦理观不仅调整了女性对应于男性的依附关系,而且改变了人对应于神的屈从地位,彰显了女性的主体人格。夏洛特通过叙述简的成长道路,似乎给当时代的中下层女性指明了一条求生存、求发展、实现真正幸福的道路。

    Purpose: To analyze the role of radiation therapy (RT) on the adverse prognostic influence of cyclooxygenase-2 (COX-2) expression on Reed-Sternberg (RS) cells, in the setting of early Hodgkin lymphoma (HL) treated with ABVD (adriamycin, vinblastine, bleomycin, dacarbazine). Methods and Materials: In the present study we retrospectively investigated the prognostic value of COX-2 expression in a large (n=143), uniformly treated early HL population from the Spanish Network of HL using tissue microarrays. Univariate and multivariate analyses were done, including the most recognized clinical variables and the potential role of administration of adjuvant RT. Results: Median age was 31 years; the expression of COX-2 defined a subgroup with significantly worse prognosis. Considering COX-2{sup +} patients, those who received RT had significantly better 5-year progression-free survival (PFS) (80% vs 54% if no RT; P=.008). In contrast, COX-2{sup −} patients only had a modest, nonsignificant benefit from RT in terms of 5-year PFS (90% vs 79%; P=.13). When we compared the outcome of patients receiving RT considering the expression of COX-2 on RS cells, we found a nonsignificant 10% difference in terms of PFS between COX-2{sup +} and COX-2{sup −} patients (P=.09), whereas the difference between the 2 groups was important (25%) in patients not receiving RT (P=.04). Conclusions: Cyclooxygenase-2 RS cell expression is an adverse independent prognostic factor in early HL. Radiation therapy overcomes the worse prognosis associated with COX-2 expression on RS cells, acting in a chemotherapy-independent way. Cyclooxygenase-2 RS cell expression may be useful for determining patient candidates with early HL to receive consolidation with RT.

    Full Text Available The increased number of complex functional units exerts high power-density within a very-large-scale integration (VLSI chip which results in overheating. Power-densities directly converge into temperature which reduces the yield of the circuit. An adverse effect of power-density reduction is the increase in area. So, there is a trade-off between area and power-density. In this paper, we introduce a Shared Reed-Muller Decision Diagram (SRMDD based on fixed polarity AND-XOR decomposition to represent multioutput Boolean functions. By recursively applying transformations and reductions, we obtained a compact SRMDD. A heuristic based on Genetic Algorithm (GA increases the sharing of product terms by judicious choice of polarity of input variables in SRMDD expansion and a suitable area and power-density trade-off has been enumerated. This is the first effort ever to incorporate the power-density as a measure of temperature estimation in AND-XOR expansion process. The results of logic synthesis are incorporated with physical design in CADENCE digital synthesis tool to obtain the floor-plan silicon area and power profile. The proposed thermal-aware synthesis has been validated by obtaining absolute temperature of the synthesized circuits using HotSpot tool. We have experimented with 29 benchmark circuits. The minimized AND-XOR circuit realization shows average savings up to 15.23% improvement in silicon area and up to 17.02% improvement in temperature over the sum-of-product (SOP based logic minimization.

    Highlights: ► It is necessary to improve existing and develop new sludge management techniques. ► One method is dewatering and biodegradation of compounds in constructed wetlands. ► The result showed high reduction of all tested parameters after treatment. ► Plants improve degradation and Phragmites australis is tolerant to xenobiotics. ► The amount of sludge could be reduced by 50–70%. - Abstract: Since the mid-1970s, Sweden has been depositing 1 million ton d.w sludge/year, produced at waste water treatment plants. Due to recent legislation this practice is no longer a viable method of waste management. It is necessary to improve existing and develop new sludge management techniques and one promising alternative is the dewatering and treatment of sludge in constructed wetlands. The aim of this study was to follow reduction of organic carbon, BOD and nutrients in an industrial sludge containing nitro-aromatic compounds passing through constructed small-scale wetlands, and to investigate any toxic effect such as growth inhibition of the common reed Phragmites australis. The result showed high reduction of all tested parameters in all the outgoing water samples, which shows that constructed wetlands are suitable for carbon and nutrient removal. The results also showed that P. australis is tolerant to xenobiotics and did not appear to be affected by the toxic compounds in the sludge. The sludge residual on the top of the beds contained low levels of organic carbon and is considered non-organic and could therefore be landfilled. Using this type of secondary treatment method, the amount of sludge could be reduced by 50–70%, mainly by dewatering and biodegradation of organic compounds.

    During thermal conversion (gasification and combustion) of biomasses solid residues (ashes) are produced which should be returned to the forests and the agricultural areas respectively as fertilizers. This aims for avoiding the use of synthetic fertilizers and the necessity of deposition of such ashes. However, to do so the heavy metal concentrations of ashes may not exceed specific limited values. To investigate in the heavy metal behaviour during biomass conversion a bench scale plant was erected. With this plant the influences of the conversion temperature (1000-1300 C), of the gas atmosphere (reducing, oxidising) and of the dedusting temperature (300-750 C) during gasification and combustion of Chinese reed are determined. In essence the plant consists of an entrained flow reactor (length of reaction zone: 2500 mm; inner diameter: 70 mm) and a candle barrier filter with 6 rigid filter elements (DIA-Schumalith 10-20). The biomass flow rate is 6 kg/h and the operating pressure is about 1,2 bar. The test results for the gasification of Chinese reed are presented in form of metal concentrations of Chinese reed original ash, slag, fly ash and product gas concerning the elements Si, Al, Ca, Fe, Mg, Na, K, Pb, Zn, Cr, Cu and Ni. The data represent average values for a range of temperatures from 1000 to 1160 C with a constant filter temperature of 550 C. In order to better illustrate the behaviour of the metals during thermal processing enrichment (concerning the fly ash) and deficiency (concerning the slag) factors for the elements are introduced. The concentrations of the non or hardly volatile elements like Si, Al, Ca, Fe, Mg and K are nearly similar in the original ash, the slag and the fly ash. The concentrations of the environmentally relevant heavy metals like Cr, Pb and Zn in the slag are significantly lower than in the original ash. These heavy metals are enriched in the fly ash. A comparison between the measured fly ash concentrations and the corresponding

    The target of this project is to investigate if rape seed based fuel oil and diesel fuel component, agrofiber and solid fuel from other annual crops could be produced effectively as an alternative to existing non economical biodiesel-RME and ethanol production. Without heavy tax incentives the biodiesel and grain ethanol can not compete with conventional liquid fuels, the present EU fuel tax legislation will not permit any permanent tax incentives for commercial scale operations. Based on several studies by VTT the rape seed oil will be 30 % cheaper than RME and the utilization as a component 10-30 % blended to heating oil or diesel fuel might the most flexible solution. Neste Oy has carried out the combustion tests with 20 kW boiler and VTT the diesel engine tests with 20 % unprocessed rape seed oil mixtures, the oil was delivered by Mildola Oy. For the co-utilization of annual crops and straw, several laboratory scale combustion and flash pyrolysis tests have been carried out by VTT with straw, reed canary grass etc. In a flash pyrolysis process, the alkalies will remain in the char and a low alkali level bio oils can be produced. As a final step in order to reach the zero subsidy target, an extensive laboratory work is carried out to produce agrofibre from flax, reed canary grass and wheat straw. During the next months an overall economic calculations will be carried out in Finnish, Danish and Italian conditions as an EU-Apas project in order to see the competitiveness of such integrated concepts to conventional RME and reed canary grass combustion

    The avifauna of the Mariana Islands, an archipelago in the western Pacific, faces the threats of rapid economic development and the spread of non-native species, particularly a devastating predator, Brown Tree Snake Boiga irregularis. In this paper, we examine the status and trends of the land bird fauna of Saipan Island based on three island-wide surveys conducted in 1982, 1997, and 2007. During this period, the human population on Saipan increased more than four-fold and much of the island has been developed. The surveys employed standard point-transect methods based on Distance Sampling. Remarkably, we found nearly all species of land birds - 11 native species and three introduced species - to be common or abundant. The exception was the Micronesian Megapode Megapodius laperouse, a historically rare species that was not observed on the 2007 survey, although it does persist on Saipan and other Mariana islands. A comparison of species densities among the three surveys showed that seven species, mainly fruit and seed-eaters, had increased and three species of insectivorous birds had decreased - Rufous Fantail Rhipidura rufifrons, Nightingale Reed-warbler Acrocephalus luscinia, and Golden White-eye Cleptornis marchei. Of these three, Nightingale Reed-warbler is listed as Endangered on the IUCN Red List and as an Endangered Species by the U.S. Fish and Wildlife Service. Reed-warbler densities on Saipan decreased by more than half between 1982 and 2007. Although point transect sampling worked well for this species, density estimates and trends assessment could be improved by reallocating sampling stations among habitats and by more frequent sampling. ??

    Miscanthus and reed canary grass (RCG) are C4 and C3 perennial grasses which are popular in Europe as energy crops. Although Miscanthus is relatively chilling tolerant compared to other C4 species, its production in northern Europe is still constrained by cold temperature. A more chilling tolerant...... Miscanthus cultivar which can emerge early in the spring would utilize more solar radiation and produce higher biomass yields. In this study, using MiscanFor model, we estimated potential biomass yield of Miscanthus in current and future climates with the assumption that breeding would provide a chilling...

In a flash pyrolysis process, the alkalies will remain in the char and a low alkali level bio oils can be produced. As a final step in order to reach the zero subsidy target, an extensive laboratory work is carried out to produce agro fibre from flax, reed canary grass and wheat straw. The laboratory results show that a good quality pulp can be produced to be mixed with conventional wood fibres, the quality of flax pulp is even better compared to conventional pulp.

    Reed canary grass (RCG, Phalaris arundinacea L.) is a suitable energy crop for cultivation in northern peatlands. However, the atmospheric impact of RCG cultivation as influenced by harvest frequency and fertilization is not clear. Here, we compared the biomass yield and greenhouse gas (GHG......) balance for RCG cultivation in peatlands affected by cutting frequency and fertilizer managements. The managements included one-cut (OC) and two-cut (TC) systems that were either fertilized (TC-F) or unfertilized (TC-U) after the first cut in summer. Biomass yield of OC, TC-F and TC-U were 12, 16 and 11...

    The ability of Phragmites australis to take up heavy metals (Co, Ni, Mo, Cd, Pb, Cr, Cu, Fe, Mn, Zn, and Hg) and other trace elements (As, Se, Ba), from estuarine sediments was investigated using a pilot plant experimental approach. Bioaccumulation (BCF) and translocation factors (TF) were calculated in vegetative and senescence periods for two populations of P. australis, from contaminated (MIC) and non-contaminated (GAL) estuarine sediments, respectively, both growing in estuarine contaminated sediment (RIA) from ría del Carmen y Boo, Santander Bay, Spain. The highest BCF values were obtained for Ni (0.43), Ba (0.43) Mo (0.36), Cr (0.35), and Cd (0.31) for plants collected from site GAL following the senescence period. The highest BCF values recorded for plants collected from MIC following the senescence period were for Mo (0.22) and Cu (0.22). Following senescence, plants collected from GAL and MIC presented TF>1 for Ni, Mo, Se, and Zn, and in addition plants collected from MIC presented TF>1 for Ba, Cr, and Mn. A substantial increase of Micedo's rhizosphere, six times higher than Galizano's rhizosphere, suggested adaptation to contaminated sediment. The evaluated communities of P. australis demonstrated their suitability for phytoremediation of heavy metals contaminated estuarine sediments.

  14. Nutrient supply to reed canary grass as a bioenergy crop. Intercropping and fertilization with ash or sewage sludge

    Lindvall, Eva

    2012-07-01

    Production of renewable energy from herbaceous crops on agricultural land is of great interest since fossil fuels need to be replaced with sustainable energy sources. Reed canary grass (RCG), Phalaris arundinacea L. is an interesting species for this purpose. The aim of this thesis was to study different approaches to reduce the requirement of mineral fertilizers in RCG production for bioenergy purposes. Paper I describes a study where fertilization effects and risk of heavy metal enrichment were studied, using annual applications of ash for seven years. Ash from co-combustion of RCG and municipal wastes (mixed ash), pure RCG ash and commercial fertilizers were compared. The experiment was harvested each spring. Paper II describes an ongoing study in which the effects of intercropping RCG in mixture with nitrogen-fixing perennial legumes are examined in two experiments, in combination with various fertilization treatments. Three fertilization treatments were applied: high N, low N (half of the high N) and low N + RCG ash/sewage sludge. A delayed harvest method was used; cutting the biomass in late autumn and harvesting in spring. Besides dry matter yield, the N-fixation rate was estimated. The results from paper I showed no differences between treatments in the dry matter yields or in the heavy metal concentrations in the biomass. Soil samples, taken when the experiment was finished, showed differences between treatments for Cd, Pb and Zn only in the uppermost soil level, highest levels for the mixed ash treatment. The results in paper II showed that at one site the legume proportion in the mixtures was low and did not affect RCG growth negatively. The high N treatment gave a higher spring yield than the low N treatments. Mean rates of N2-fixation in the first production year were 12-28, 33-40 and 55 kg N ha-1 kg for goat's rue (Galega orientalis Lam.), red clover (Trifolium pratense L.), and alsike clover (Trifolium hybridum L.), plots, respectively.

    In molecular dynamics (MD) simulations, free-energy differences are often calculated using free energy perturbation or thermodynamic integration (TI) methods. However, both techniques are only suited to calculate free-energy differences between two end states. Enveloping distribution sampling (EDS) presents an attractive alternative that allows to calculate multiple free-energy differences in a single simulation. In EDS, a reference state is simulated which "envelopes" the end states. The challenge of this methodology is the determination of optimal reference-state parameters to ensure equal sampling of all end states. Currently, the automatic determination of the reference-state parameters for multiple end states is an unsolved issue that limits the application of the methodology. To resolve this, we have generalised the replica-exchange EDS (RE-EDS) approach, introduced by Lee et al. [J. Chem. Theory Comput. 10, 2738 (2014)] for constant-pH MD simulations. By exchanging configurations between replicas with different reference-state parameters, the complexity of the parameter-choice problem can be substantially reduced. A new robust scheme to estimate the reference-state parameters from a short initial RE-EDS simulation with default parameters was developed, which allowed the calculation of 36 free-energy differences between nine small-molecule inhibitors of phenylethanolamine N-methyltransferase from a single simulation. The resulting free-energy differences were in excellent agreement with values obtained previously by TI and two-state EDS simulations.

  16. Metaproteomics analysis of the functional insights into microbial communities of combined hydrogen and methane production by anaerobic fermentation from reed straw.

    Directory of Open Access Journals (Sweden)

    Xuan Jia

    Full Text Available A metaproteomic approach was used to analyse the proteins expressed and provide functional evidence of key metabolic pathways in the combined production of hydrogen and methane by anaerobic fermentation (CHMP-AF for reed straw utilisation. The functions and structures of bacteria and archaea populations show significant succession in the CHMP-AF process. There are many kinds of bacterial functional proteins, mainly belonging to phyla Firmicutes, Proteobacteria, Actinobacteria and Bacteroidetes, that are involved in carbohydrate metabolism, energy metabolism, lipid metabolism, and amino acid metabolism. Ferredoxin-NADP reductase, present in bacteria in genus Azotobacter, is an important enzyme for NADH/NAD+ equilibrium regulation in hydrogen production. The archaeal functional proteins are mainly involved in methane metabolism in energy metabolism, such as acetyl-CoA decarboxylase, and methyl-coenzyme M reductase, and the acetic acid pathway exhibited the highest proportion of the total. The archaea of genus Methanosarcina in phylum Euryarchaeota can produce methane under the effect of multi-functional proteins through acetic acid, CO2 reduction, and methyl nutrient pathways. The study demonstrates metaproteomics as a new way of uncovering community functional and metabolic activity.

This also regulates the process from its protein levels and improves the efficiency of biogas production using reed straw biomass.

    A metaproteomic approach was used to analyse the proteins expressed and provide functional evidence of key metabolic pathways in the combined production of hydrogen and methane by anaerobic fermentation (CHMP-AF) for reed straw utilisation. The functions and structures of bacteria and archaea populations show significant succession in the CHMP-AF process. There are many kinds of bacterial functional proteins, mainly belonging to phyla Firmicutes, Proteobacteria, Actinobacteria and Bacteroidetes, that are involved in carbohydrate metabolism, energy metabolism, lipid metabolism, and amino acid metabolism. Ferredoxin-NADP reductase, present in bacteria in genus Azotobacter, is an important enzyme for NADH/NAD+ equilibrium regulation in hydrogen production. The archaeal functional proteins are mainly involved in methane metabolism in energy metabolism, such as acetyl-CoA decarboxylase, and methyl-coenzyme M reductase, and the acetic acid pathway exhibited the highest proportion of the total. The archaea of genus Methanosarcina in phylum Euryarchaeota can produce methane under the effect of multi-functional proteins through acetic acid, CO2 reduction, and methyl nutrient pathways. The study demonstrates metaproteomics as a new way of uncovering community functional and metabolic activity. The combined information was used to identify the metabolic pathways and organisms crucial for lignocellulosic biomass degradation and biogas production. This also regulates the process from its protein levels and improves the efficiency of biogas production using reed straw biomass. PMID:28817657

    From uranium mining areas, in particular, the radionuclides are usually discharged to the environment during the mining and milling process. At the former uranium mine Zirovski vrh, Slovenia, mine waste and mill tailings were deposited at the Jazbec site and the Borst site, respectively. Plants grown in soils contaminated with the seepage waters from tailings may represent radiological concern if radionuclides from the uranium decay chain are transferred into the food chain. Uranium is usually accumulated in the roots and translocated to the shoots in limited amounts. Uranium plant accumulators are usually plants from Brassicaceae and Poaceae families. A common reed (Phragmites australis (Cav.) Trin. ex Steud.), a tall perennial grass, growing in a wetland habitats, accumulates metals in the above-ground parts. It may be used for phytoremediation of uranium-contaminated soils, because of high biomass production and high metal-accumulation potential. Preliminary results of radionuclide contents measured in such plants, growing on the deposit tailings are presented. A common reed, that was grown on the Borst tailings pile accumulated 8.6 {+-} 8 mBq/g dry weight (d.w.) and 2.4 {+-} 2 mBq/g dry weight (d.w.) of {sup 238}U in leaves and stems, respectively. In the paper, activity concentrations of other nuclides, i.e. {sup 226}Ra, {sup 210}Pb and {sup 40}K are also shown and discussed.

    field study was designed to compare the biomass yields and GHG balances for RCG cultivated on peatlands with different cutting frequency and fertilizer managements. The managements included one-cut (OC) and two two-cut (TC) systems that were either fertilized (TC-F) or unfertilized (TC-U) after the first cut in summer. Apart from CO{sub 2} flux measurements, fluxes of N{sub 2}O and CH{sub 4} were also measured with opaque closed chambers in the period between first and second (final) harvest of the TC managements. Overall, the TC-F could not improve the GHG balance during cultivation, but when the potential for fossil fuel displacement by the energy crop is included in a detailed GHG life cycle perspective, the larger amount of biomass could replace more fossil fuel and offset at least some of the higher emissions from the system. The second focus of this PhD study was to examine the influence of crop maturity, harvest frequency and fertilizer management of RCG on specific methane yield (SMY) and methane yield per hectare. Significant effect of crop maturity was observed for SMY which ranged from 384 to 315 and from 412 to 283 normal litre (kg VS){sup -1} for leaf and stem, respectively. The TC-F management produced 45% more methane per hectare than the OC management. The SMY was moderately correlated with the concentrations of fibre components but the regression models developed to predict SMY using fibre components were not convincing. In another study, possibility of using near infrared reflectance spectroscopy (NIRS) as a rapid alternative method to the conventional time consuming batch methods for prediction of SBY, SMY and kinetics of biogas yield (k-SBY) of RCG biomass was explored. Part of the ground RCG biomass used in the batch assays was used for NIR spectra measurements. Calibration models were developed from the NIRS spectra using partial least square (PLS) regression. The calibration performance of SBY (R{sup 2} = 0.68, RPD = 1.83) and k-SBY (R{sup 2} = 0

    Holstein-Friesian steer beef production is renowned globally as a secondary product of the milk industry. Grass feeding is a common practice in raising Holstein steers because of its low cost. Furthermore, grass feeding is an alternative way to produce beef with a balanced n-6 to n-3 fatty acids (FAs) ratio. However, the performance and meat quality of Holstein-Friesian cattle is more likely to depend on a high-quality diet. The aim of this study was to observe whether feeding two mixed diets; a corn-based total mixed ration (TMR) with winter ryegrass (Lolium perenne) or flaxseed oil-supplemented pellets with reed canary grass haylage (n-3 mix) provided benefits on carcass weight, meat quality and FA composition compared with cattle fed with reed canary grass (Phalaris arundinacea) haylage alone. In all, 15 21-month-old Holstein-Friesian steers were randomly assigned to three group pens, were allowed free access to water and were fed different experimental diets for 150 days. Blood samples were taken a week before slaughter. Carcass weight and meat quality were evaluated after slaughter. Plasma lipid levels and aspartate aminotransferase (AST), γ-glutamyl transpeptidase (GGT), creatine kinase (CK) and alkaline phosphatase (ALP) activities were determined. Diet did not affect plasma triglyceride levels and GGT activity. Plasma cholesterol levels, including low-density and high-density lipoproteins, were higher in both mixed-diet groups than in the haylae group. The highest activities of plasma AST, CK and ALP were observed in the haylage group, followed by n-3 mix and TMR groups, respectively. Carcass weight was lower in the haylage group than in the other groups and no differences were found between the TMR and n-3 mix groups. Although the n-3 mix-fed and haylage-fed beef provided lower n-6 to n-3 FAs ratio than TMR-fed beef, the roasted beef obtained from the TMR group was more acceptable with better overall meat physicochemical properties and sensory scores

    Nitrogen (N) fertilization is necessary for growth and development of plants but it may also causes an increased metal uptake by plants due to changes of physiochemical properties of the elements in soil. The research in phytoremediation and phytomining conducted so far has revealed that the effect of nitrogen fertilizers initially depends on the form of application, as N is the only element that can be readily utilized by plants in its cationic (ammonia) or anionic form (nitrate) causing several effects in soil-plant system. However, to our knowledge most of the recent studies only documented an improvement of yield parameters and the uptake of heavy metals by plants as a result of different forms of N-fertilization. Here we report the result of a field experiment were we tried to obtain more information about the effects of form of N-fertilization on uptake of As, Pb, Sc Ge and U in reed canary grass (Phalaris arundinacea L.). In this study, reed canary grass was grown on 15 plots (4 m² each) under field conditions on a semi-field lysimer at the off-site soil recycling and remediation center in Hirschfeld (Saxony, Germany). To test the effects of a fertilization with different N-forms on the accumulation, the plots plants received 5 g N / m² in three doses as NH4SO4, Mg(NO3)2 or NH4NO3. The geometrical arrangement of plots was randomized and every treatment was fivefold replicated. After a 50 day period of plant growth, the plants were harvested and concentrations of trace metals in the shoots were measured with ICP-MS. As a result of the different N-treatments we found that in plants treated with NH4SO4 concentrations of Pb and As as well as of Sc, Ge and U were significantly increased in plant tissues compared to plants treated with NH4NO3. Furthermore, no significant changes in mineral composition of plants between the Mg(NO3)2 and NH4NO3 treatments could be observed. Our interpretation of these results is that it might be an effect of the acidification of

    In two different types of district heating combustion plants in Denmark, normally using straw as fuel, the energy grass Reed canary grass (summer harvested) has been tested as a new fuel. The combustion plant in Ringsted burns the fuel as whole bales with the so called `cigar method`. In Nykoebing the fuel is burned on a rust as unpacked bales using a straw divider to divide the bales. The heating effect of the combustion plants is 4.5 MW and 4.0 MW, respectively. For both plants, there was no handling or technical problem observed in the test with Reed canary grass compared to straw. The analysis of the emission to air shows high average values for CO- and NO{sub x} during the test period which is unacceptable according to Swedish limit values for emissions. For combustion plants with a heating effect over 10 MW, the limit values for NO{sub x} is 100-200 mg/MJ. For smaller plants there are no limits values today but in the future demands for limitation of NO{sub x} emission may come. For both plants, the O{sub 2}-content in fumes varied a lot, with a high mean value, about 10%. The content of chlorine in straw and energy grass can reach high levels. Most of the chlorine binds up in the ash (KCl), and therefore the emission of HCl are low. The emission to air of SO{sub x}, which is 100 mg/MJ, is below the limit value for smaller plants. The variation of moisture and the low density are the properties of grass and straw that mainly causes problems in the combustion and gives high emission levels. Today it seems to be necessary to press the material into fuel briquetts or fuel pellets to get a better combustion, that can meet environmental demands. (7 figs., 17 tabs.).

    Introducing fuels from agricultural crops into the heat and power sector in Sweden is a desired and needed development, thus it is connected to some obstacles. For the crop producers it is important to use the most efficient handling for harvest, collection, loading and transport technology in order to reach low production costs. For the fuel consumers it is of high importance that these fuels work together with other utilized fuels in mixtures without complications. This includes fuel mixing, fuel feeding, combustion behavior and ash transformation mechanisms. Specifically for the combustion process, gaseous and particle emissions, ash behavior and deposit formation on cooled surfaces should not be negatively effected by mixing in agricultural crops. In this study these aspects of the energy crop reed canary grass (RCG) have been examined. The recommended harvest period for harvesting RCG in Sweden is during springtime when the crop from the year before is collected, called delayed harvest. During this period the grass is very dry and has been harvested in this project with an average water content of 11,3 %. Two major different harvest systems have been tested. One where the energy grass is chopped directly in the field by a chopper connected to a wagon. The other system was based on baling the crop with round balers or big square balers. The chopped or baled material is transported 6 km to a farm center or terminal for unloading. Further transport to CHP (Combined Heat and Power) plant, 12 km, was done with road truck (135 m3). In the case of field chopped RCG the mixing of the other fuels has been easily done since the material was well chopped (40-50 mm). The RCG was mixed into a mixture of peat and wood to a share of 10-12% of the total energy content of the mixture. Also the baled material was transported to a farm centre or terminal for unloading the farm wagon and loading on a road truck (135 m3). In this case an additional procedure is needed for chopping

    Environmental protection requires effective monitoring system of radionuclide contamination and radiobiological effects as well as development of their prevention and minimizing measures for humans and biota. There is a majority of conventional techniques for living organisms' habitat quality assessment. One of the most widespread, convenient and accessible ones, is the seed progeny analysis, for example of conifers, cereals and wild herbaceous plants. Availability of vitality, growth, mutability indexes and abnormalities of vascular plant germs for environment quality express assessment was discussed in numerous publications. However, this point is studied insufficiently concerning aquatic vascular plants, forming communities playing significant role in radionuclides distribution in contaminated water bodies. Common reed (Phragmites australis (Trin) Ex. Steud) is a widespread species mostly dominating in air-aquatic vascular plant communities of freshwater bodies; it is a first-order {sup 137}Cs and {sup 90}Sr accumulating species. To assess the common reed germs growth indexes availability, seeds were sampled in polygon water bodies of different radionuclide contamination levels and 0.7-22 mcGy h{sup -1} total absorbed dose range, within the Chernobyl Exclusion Zone. In water bodies with background level of radionuclide contamination, for comparison, total absorbed dose varied in range of 0.03-0.3 mcGy h{sup -1}. Series of seeds germination experiments was carried out in laboratory conditions. Complex of germs indexes was investigated, conditionally divided into three groups: (1) Vitality indexes. In course of experiment series, vitality was assessed via germinating energy, germinating ability indexes, germination period (first and last germ appearance) and survivability study; (2) Growth indexes. Root and leaf length, occurrence of plant groups with different vegetative organs length were determined for germs growth speed assessment; (3) Teratological

    Here, an increasing demand for renewable energy sources has spurred interest in high-biomass crops used for energy production. Species potentially well-suited for biofuel production in the seasonally wet organic Everglades Agricultural Area (EAA) of Florida include giant reed (Arundo donax), elephant grass (Pennisetum Purpureum), energycane (Saccharum spp.), and sugarcane (Saccharum spp.). The objectives in this study were to evaluate the role of fluctuating water tables on the morphology, physiology, and early season growth of these four genotypes. The candidate genotypes were grown in a greenhouse under three water table depths, defined by distance of the water table from the soil surface: two constant water tables (-16 cm and -40 cm) along with a flood cycle (2 weeks of flood to the soil level followed by 2 weeks at -40 cm from the soil level). The genotypes included CP 89-2143 (sugarcane), L 79-1002 (energycane), Merkeron (elephant grass), and wild type (giant reed). The experiment was repeated for plant cane, first ratoon, and successive plant cane crop cycles. Reductions in dry matter yield were observed among genotypes subjected to the -40 cm drained, periodically flooded (40F) water table relative to the -40 cm constant (40C) or -16 cm constant (16C). Plant cane dry weights were reduced by 37% in giant reed, 52% in elephant grass, 42% in energycane, and 34% in sugarcane in the 40F compared to 40C water table treatments. Similarly, in the first ratoon crop dry weights were reduced by 29% in giant reed, 42% in elephant grass, 27% in energycane, and 62% in sugarcane. In plant cane and successive plant cane, average total dry weight was greatest for elephant grass whereas ratoon total dry weight was greatest for energycane. Genotype had more pronounced effects on physiological attributes than water table including the highest stomatal conductance and SPAD values in giant reed, and the highest stalk populations in elephant grass and

    Full Text Available French Reed Bed (FRB is a particular constructed wetland (CW solution which receives raw wastewater. Data from the full-scale FRB wastewater treatment plant of Castelluccio di Norcia (center of Italy were collected to show the FRB capability to minimize the operational and management (O&M costs. The system was designed to treat wastewater variable from 200 person equivalent (PE in off-season up to 1000 PE. Data from 2014 up to 2016 showed high removal efficiency in line with French experiences with FRBs. An interview was conducted with the Water Utility to estimate the operational and maintenance (O&M costs faced by the WWTP, which allowed us to detail the O&M costs for energy consumption, water quality samples, and personnel for inspection. Other O&M expenditure items were estimated on the basis of parametric costs from the executive design. The FRB O&M costs in euro for 500–1000 PE (6–11 € PE−1 year−1 resulted from 5 to 13 lower in comparison to those reported for classical activated sludge systems in an Italian context (45–90 € year−1. The low O&M costs are mainly due to the limited energy consumed and to the minimized costs of sludge management.

    Empirical greenhouse gas (GHG) flux estimates from diverse peatlands are required in order to derive emission factors for managed peatlands. This study on a drained fen peatland quantified the annual GHG balance (Carbon dioxide (CO2), nitrous oxide (N2O), methane (CH4), and C exported in crop yield) from spring barley (SB) and reed canary grass (RCG) using static opaque chambers for GHG flux measurements and biomass yield for indirectly estimating gross primary production (GPP). Estimates of ecosystem respiration (ER) and GPP were compared with more advanced but costly and labor-intensive dynamic chamber studies. Annual GHG balance for the two cropping systems was 4.0 ± 0.7 and 8.1 ± 0.2 Mg CO2-Ceq ha(-1) from SB and RCG, respectively (mean ± standard error, n = 3). Annual CH4 emissions were negligible (peatland cropped to SB and RCG and presented a valid alternative to estimating the full GHG balance by dynamic chambers.

    This study investigated the performance of sludge drying reed beds (SDRB) at full- and pilot-scale treating sludge from septic tanks in the city of Belo Horizonte, Brazil. The treatment units, planted with Cynodon spp., were based on an adaptation of the first-stage of the French vertical-flow constructed wetland, originally developed for treating sewage. Two different operational phases were investigated; in the first one, the full-scale unit was used together with six pilot-scale columns in order to test different feeding strategies. For the second phase, only the full-scale unit was used, including a recirculation of the filtered effluent (percolate) to one of the units of the French vertical wetland. Sludge application was done once a week emptying a full truck, during 25 weeks. The sludge was predominantly diluted, leading to low solids loading rates (median values of 18 kgTS m(-2) year(-1)). Chemical oxygen demand removal efficiency in the full-scale unit was reasonable (median of 71%), but the total solids removal was only moderate (median of 44%) in the full-scale unit without recirculation. Recirculation did not bring substantial improvements in the overall performance. The other loading conditions implemented in the pilot columns also did not show statistically different performances.

    Invasive plants can threaten diversity and ecosystem function. We examined the relationship between the invasive Phalaris arundinacea (reed canarygrass) and species richness in beaver wetlands in Oregon, USA. Four basins (drainages) were chosen and three sites each of beaver impoundments, unimpounded areas and areas upstream of debris jams were randomly chosen in each basin for further study (n = 36). Analysis of covariance (ANCOVA) showed that the relationship between Phalaris and species richness differed significantly (p = 0.01) by site type. Dam sites (beaver impoundments) exhibited a strong inverse relationship between Phalaris and species richness (bD = a??0.15), with one species lost for each 7% increase in Phalaris cover. In contrast, there was essentially no relationship between Phalaris cover and species richness in jam sites (debris jam impoundments formed by flooding; bJ = +0.01) and unimpounded sites (bU = a??0.03). The cycle of beaver impoundment and abandonment both disrupts the native community and provides an ideal environment for Phalaris, which once established tends to exclude development of herbaceous communities and limits species richness. Because beaver wetlands are a dominant wetland type in the Coast Range, Phalaris invasion presents a real threat to landscape heterogeneity and ecosystem function in the region.

    In the years 2000-2004, reed canary grass (RCG) has been cultivated, harvested, stored, upgraded, and combusted at Umeaa Biofuel Technology Center (BTC), SLU Roebaecksdalen, Umeaa. The entire chain from the field to hot water has been handled by personnel at BTC. Data and experiences from the different handling stages have been continuously collected. In this time period, RCG has been harvested each spring. The mean harvest level on SLU properties has been approximately 4 ton DM/ha and the dry matter content at harvest has been on average 11-12 %. Winter and harvest losses has been determined to approximately 44 %, by a comparison of harvest levels in spring and harvest levels in sample squares in late fall. An alternate method of cutting in late fall, where the crop is left in the field until spring, has been tested. With this method, the risk for cutting of green shoots is eliminated and the isolating effect of the cut ley is decreasing the frost depth in the field. Three different techniques of baling have been tested: large and small square baling, and round baling. Round baling is most suitable for the conditions at BTC, because of the low availability of large square baling equipment in the area. Otherwise large square baling is more time efficient. Thus, the low weight of round baling equipment is advantageous and gives rise to less ground damages. On BTC, the RCG bales are stored outside on an asphalt area, covered with ensilage plastic on a layer of pallets. This handling procedure is working satisfactory with relatively low material losses, but when larger quantities are stored inside storage is to prefer. The economy of RCG cultivation is, as for all agricultural crops, dependent of subsidies within EU's Common Agricultural Policy (CAP). Subsidies can be received for RCG cultivation on ordinary farmland and on fallow farmland. An extra energy crop subsidy can be received for RCG cultivation on ordinary farmland if the energy crop is utilised as

    Reed Canary Grass is a promising crop for biofuel production. For reed canary grass the first year is an establishment year when the small biomass is not harvested. The second year the biomass is usually cut in late autumn but the harvest (removal of the biomass from the field) is delayed until spring. This technique has resulted in lower costs and increases in fuel quality through lower ash contents, including lower contents of chlorine, sodium and potassium. However costs for production are still high, especially establishment costs, fertilization costs and harvesting costs. The aim of this project was to test ways to cut costs per MWh by increased yields, and decreased establishment costs. The methods used have been variety trials to develop more productive plant material, intercropping with nitrogen fixing legumes to reduce the nitrogen demand of the crop, fertilization with waste material (sewage sludge, reed canary grass ash or poultry manure) and harvest at frozen ground as a strategy to reduce soil compaction and harvest damages on the crop. Reed canary grass grown as a fuel has so far been grown as a mono culture. However, when it is been grown for forage, or as a biogas crop, intercropping with legumes has been successful in some studies. In addition to NPK-fertilizers sewage sludge, ash from combustion of reed canary grass and poultry manure was used. An economic calculation showed that the establishment costs (the first two growing seasons) can be lowered by intercropping with red clover. However it is also involves more risks, related to weeds, and cannot be recommended on fallow soil with a large seed bank of weeds. A ten year old reed canary grass ley was used for the experiment. Two 25 m wide strips were harvested with a mower on November 19 2008 when the top soil was frozen. The harvested material was chopped and removed from the field the following day. The following spring, May 19 2009, the remaining reed canary grass on the field was cut with a

    The contribution of energy crops from the agricultural sector is an example of a resource that has a potential to increase substantially in the near future. However, one problem is the lack of interest in cultivating energy crops within the agricultural Several studies have shown that there are a number of reasons for farmers not becoming involved in energy crops. Besides biological aspects, market potential and profitability the farmers are also affected by the available resources on the farm, the effect of the crops on the surroundings, work load, liquidity and the perceived risks. The overall aim with the present study is to increase the knowledge about how to change farmers' attitudes regarding energy crop cultivation, i.e. making them more interested. This study also shows that there is a large fraction of farmers that generally believe they have no or little knowledge of energy crops, such as willow, reed canary grass and hemp. The fraction of farmers considering there is a larger probability of future cultivation of these crops with increased knowledge is also quite large. Energy crop cultivation does not suit everybody. Generally, growing willow and reed canary grass is an alternative for farmers having another business besides agricultural business. Characteristics for these farms are working hours <1500 hours and that the machines are partly owned

    This work considered the quantitative analysis of large written texts. To this end, the text was converted into a time series by taking the sequence of word lengths. The detrended fluctuation analysis (DFA) was used for characterizing long-range serial correlations of the time series. To this end, the DFA was implemented within a rolling window framework for estimating the variations of correlations, quantified in terms of the scaling exponent, strength along the text. Also, a filtering derivative was used to compute the dependence of the scaling exponent relative to the scale. The analysis was applied to three famous English-written literary narrations; namely, Alice in Wonderland (by Lewis Carrol), Dracula (by Bram Stoker) and Sense and Sensibility (by Jane Austen). The results showed that high correlations appear for scales of about 50-200 words, suggesting that at these scales the text contains the stronger coherence. The scaling exponent was not constant along the text, showing important variations with apparent cyclical behavior. An interesting coincidence between the scaling exponent variations and changes in narrative units (e.g., chapters) was found. This suggests that the scaling exponent obtained from the DFA is able to detect changes in narration structure as expressed by the usage of words of different lengths.

Ante la dificultad de tener modelos animales para varios grupos de enfermedades, la experimentación en seres humanos se hizo necesaria, incluyendo la autoinoculación de los investigadores. La historia de las investigaciones sobre la fiebre amarilla en Cuba es una experiencia paradigmática y fundamental de la salud pública y ejemplo del triunfo del planteamiento de la infectología.

    The aim of the study was to investigate the effects of climate change on soil hydrology and carbon (C) fluxes in boreal peatland ecosystems, with implications for the feasibility of cultivating reed canary grass (Phalaris arundinacea, L; RCG) as a way to restore the C sink in cutaway peatlands under Finnish conditions. First, hydrological models were developed for pristine peatland ecosystems and the cutaway peatlands under RCG cultivation. Concurrently, the hydrological responses to varying climatic forcing and mire types were investigated for these ecosystems. Thereafter, process-based models for estimating the seasonal and annual C exchanges were developed for the pristine mires and cutaway peatlands. The C models incorporated the hydrological models for corresponding ecosystems. Model simulations based on the climate scenarios (ACCLIM, developed by the Finnish Meteorological Institute, FMI) were further carried out to study the impacts of climate change on the C exchanges in the peatland ecosystems during the 21st century. The simulation showed that the water table (WT) in the pristine Finnish mires would draw down slightly during the 21st century. Such a chance in WT would be related to a decrease in the CO{sub 2} sink but an increase in the CH{sub 4} source at the country scale, as driven mainly by the rising temperature (Ta) and increasing precipitation (P). These changes in CO{sub 2}/ CH{sub 4} fluxes would decrease the total C-greenhouse gas (GHG) sink (CO{sub 2} equilibrium) by 68% at the country scale, and the changes would be more pronounced toward the end of the century. The majority of pristine fens in southern and western Finland and the pristine bogs near the coastal areas would become centurial CO{sub 2} sources under the changing climate. On the other hand, the major distribution of fens in northern Finland would act to increase the CH{sub 4} source at the country scale, whereas the CH{sub 4} emission would tend to decrease with WT in the southern

    Full Text Available The analysis of in situ measurements of velocity distribution in the floodplain of the lowland river has been carried out. The survey area was located on a bypass channel of the Warta River (West of Poland which is filled with water only in case of flood waves. The floodplain is covered by grassland and reed marsh habitats. The velocity measurements were performed with an acoustic Doppler current profiler (ADCP in a cross-section with a bed reinforced with concrete slabs. The measured velocities have reflected the differentiated impact of various vegetation types on the loss of water flow energy. The statistical analyses have proven a relationship between the local velocities and the type of plant communities.

  9. Action during body perception: processing time affects self-other correspondences.

    The accurate perception of other people and their postures is essential for functioning in a social world. Our own bodies organize information from others to help us respond appropriately by creating self-other mappings between bodies. In this study, we investigated mechanisms involved in the processing of self-other correspondences. Reed and Farah (1995) showed that a multimodal, articulated body representation containing the spatial relations among parts of the human body was accessed by both viewing another's body and moving one's own. Use of one part of the body representation facilitated the perception of homologous areas of other people's bodies, suggesting that inputs from both the self and other activated the shared body representation. Here we investigated whether this self-other correspondence produced rapid facilitation or required additional processing time to resolve competing inputs for a shared body representation. Using a modified Reed and Farah dual-task paradigm, we found that processing time influenced body-position memory: an interaction between body-part moved and body-part attended revealed a relative facilitation effect at the 5 s ISI, but interference at the 2 s ISI. Our results suggest that effective visual-motor integration from the self and other requires time to activate shared portions of the spatial body representation.

    The observation that older adults show enhanced cognition for emotionally positive information has been labeled the positivity effect (Reed, Chan, & Mikels, 2014). According to the Socioemotional Selectivity Theory (SST, Carstensen, 1991), a prominent lifespan development theory, cognition is strongly influenced by motivational goals, and these goals are impacted by subjective time perspective. Although the positivity effect is most commonly observed in older adults, as age usually co-varies with time perspective, the SST posits that time perspective, not age, is the key explanatory factor of positivity. We examined the effects of these predictors on positivity in an episodic memory task in younger and older adults and found that age, not time perspective, was a key predictor of memory positivity. Our results add to the growing literature that challenge the notion that time perspective is the driving force behind age-related differences in emotional processing and functioning.

    Full Text Available Timing optimization for logic circuits is one of the key steps in logic synthesis. Extant research data are mainly proposed based on various intelligence algorithms. Hence, they are neither comparable with timing optimization data collected by the mainstream electronic design automation (EDA tool nor able to verify the superiority of intelligence algorithms to the EDA tool in terms of optimization ability. To address these shortcomings, a novel verification method is proposed in this study. First, a discrete particle swarm optimization (DPSO algorithm was applied to optimize the timing of the mixed polarity Reed-Muller (MPRM logic circuit. Second, the Design Compiler (DC algorithm was used to optimize the timing of the same MPRM logic circuit through special settings and constraints. Finally, the timing optimization results of the two algorithms were compared based on MCNC benchmark circuits. The timing optimization results obtained using DPSO are compared with those obtained from DC, and DPSO demonstrates an average reduction of 9.7% in the timing delays of critical paths for a number of MCNC benchmark circuits. The proposed verification method directly ascertains whether the intelligence algorithm has a better timing optimization ability than DC.

    Cooley and Reed's active interest measurement approach was combined with Guttman's Facet Design to construct a systematic instrument for the assessment of the impact of an environmental science course on students' behavior outside school. A quasimatched design of teacher allocation to the experimental and control groups according to their preferred teaching style was used. A kind of dummy control curriculum was devised to enable valid comparative evaluation of a new course which differs from the traditional one in both content and goal. This made it possible to control most of the differing factors inherent in the old and new curriculum. The research instrument was given to 1000 students who were taught by 28 teachers. Students who learned according to the experimental curriculum increased their leisure time activities related to the environmental science curriculum significantly. There were no significant differences between boys and girls and between students with different achievement levels.

    2010-01-01

    Analysis of residence time distribution (RTD) has been conducted for the UK Coal Authority's mine water treatment wetland at Lambley, Northumberland, to determine the hydraulic performance of the wetland over a period of approximately 4 years since site commissioning. The wetland RTD was evaluated in accordance with moment analysis and modelled based on a tanks-in-series (TIS) model to yield the hydraulic characteristics of system performance. Greater hydraulic performance was seen during the second site monitoring after 21 months of site operation i.e. longer hydraulic residence time to reflect overall system hydraulic efficiency, compared to wetland performance during its early operation. Further monitoring of residence time during the third year of wetland operation indicated a slight reduction in hydraulic residence time, thus a lower system hydraulic efficiency. In contrast, performance during the fourth year of wetland operation exhibited an improved overall system hydraulic efficiency, suggesting the influence of reed growth over the lifetime of such systems on hydraulic performance. Interestingly, the same pattern was found for iron (which is the primary pollutant of concern in ferruginous mine waters) removal efficiency of the wetland system from the second to fourth year of wetland operation. This may therefore, reflect the maturity of reeds for maintaining efficient flow distribution across the wetland to retain a longer residence time and significant fractions of water involved to enhance the extent of treatment received for iron attenuation. Further monitoring will be conducted to establish whether such performance is maintained, or whether efficiency decreases over time due to accumulation of dead plant material within the wetland cells.

    A historical input of trace metals into tidal marshes fringing the river Scheldt may be a cause for concern. Nevertheless, the specific physicochemical form, rather than the total concentration, determines the ecotoxicological risk of metals in the soil. In this study the effect of tidal regime on the distribution of trace metals in different compartments of the soil was investigated. As, Cd, Cu and Zn concentrations in sediment, pore water and in roots were determined along a depth profile. Total sediment metal concentrations were similar at different sites, reflecting pollution history. Pore water metal concentrations were generally higher under less flooded conditions (mean is (2.32 ± 0.08) x 10 -3 mg Cd L -1 and (1.53 ± 0.03) x 10 -3 mg Cd L -1 ). Metal concentrations associated with roots (mean is 202.47 ± 2.83 mg Cd kg -1 and 69.39 ± 0.99 mg Cd kg -1 ) were up to 10 times higher than sediment (mean is 20.48 ± 0.19 mg Cd kg -1 and 20.42 ± 0.21 mg Cd kg -1 ) metal concentrations and higher under dryer conditions. Despite high metal concentrations associated with roots, the major part of the metals in the marsh soil is still associated with the sediment as the overall biomass of roots is small compared to the sediment. - Pore water metal concentrations and metal root plaque concentration are influenced by the tidal regime

    In this paper, we experimentally demonstrated a complete real-time 4-level pulse amplitude modulation (PAM-4) Q-band radio-over-fiber (RoF) system with optical heterodyning and envelope detector (ED) down-conversion. Meanwhile, a cost-efficient real-time implementation scheme of cascaded multi-modulus algorithm (CMMA) equalization is proposed in this paper. By using the proposed scheme, the CMMA equalization is applied in the system for signal recovery. In addition, to improve the transmission performance of the system, an interleaved Reed-Solomon (RS) code is applied in the real-time system. Although there is serious power impulse noise in the system, the system can still achieve a bit error rate (BER) at below 1 × 10-7 after 25 km standard single mode fiber (SSMF) transmission and 1-m wireless transmission.

    We investigate time operators in the context of quantum time crystals in ring systems. We demonstrate that a self-adjoint time operator with a periodic time evolution can be derived for a free particle on a ring system: The conventional Aharonov-Bohm time operator is obtained by taking the infinite-radius limit. We also reveal the relationship between our time operator and a $\\mathcal PT$-symmetric time operator. We find that both time operators indeed describe the periodic time evolution of ...

    2018-01-01

    Our engagement with time is a ubiquitous feature of our lives. We are aware of time on many scales, from the briefest flicker of change to the way our lives unfold over many years. But to what extent does this encounter reveal the true nature of temporal reality? To the extent that temporal reality is as it seems, how do we come to be aware of it? And to the extent that temporal reality is not as it seems, why does it seem that way? These are the central questions addressed by Simon Prosser in Experiencing Time. These questions take on a particular importance in philosophy for two reasons. Firstly, there is a view concerning the metaphysics of time, known as the B-theory of time, according to which the apparently dynamic quality of change, the special status of the present, and even the passage of time are all illusions. Instead, the world is a four-dimensional space-time block, lacking any of the apparent dynamic features of time. If the B-theory is correct, as the book argues, then it must be explained why ...

    Full Text Available The analysis of natural phenomena applied to architectural planning and design is facing the most fascinating and elusive of the four dimensions through which man attempts to define life within the universe: time. We all know what time is, said St. Augustine, but nobody knows how to describe it. Within architectural projects and representations, time rarely appears in explicit form. This paper presents the results of a research conducted by students of NABA and of the Polytechnic of Milan with the purpose of representing time considered as a key element within architectural projects. Student investigated new approaches and methodologies to represent time using the two-dimensional support of a sheet of paper.

  7. From Territorial to Temporal Ambitions: The Politics of Time and Imagination in Massive Multiplayer Online Forecasting Games

    Directory of Open Access Journals (Sweden)

    Lonny J. Avi Brooks

    2015-09-01

    Full Text Available In 2010, the online forecasting game Urgent Evoke, produced by Jane McGonigal, former Director of Gaming at the Institute for the Future and the World Bank Institute, elicited praise by gaming critics as a model for “serious gaming.” The game promised to show how players could think about long-term solutions to urgent social problems like hunger, poverty, conflict, and climate change using the African continent as its test bed. Players imagined future temporal outcomes through remixing media. In a qualitative analysis of actual game play during the real-time introduction of the game for teaching organizational communication, Evoke became a platform for student inquiry for questioning its underlying design as an expansion of territorial and temporal conquest. Evoke served as a springboard for building a literacy of critical time among students in accessing stakeholder power to determine the future. Students challenged, created, and followed the cultural capital of promissory visions in circulation. The curriculum design for using serious and forecasting games like Evoke must account for the conceptual development of what Sarah Sharma calls critical time or chronopolitics, a hidden politics of time that shapes our approaches to cultures, organizations, and innovation. By placing spatial and temporal dynamics center stage, we investigated how serious games produce a chronopolitics of time differentiating among people by class and ethnicity. Alternative Reality Games offer the potential for building a literacy of critical forecasting time to understand the practices for anticipating the future as temporal networks of power, different and uneven.

    The idea of a Larmor clock is reexamined in the relativistic regime. We propose a concept of proper time for quantum theoretical particles. The Larmor clock can measure, under some relevant conditions, the proper time that passes while the particle stays in a space region. Our approach to Larmor clock is different than those of other researchers in the following two aspects: our concept of Larmor clock does not distinguish whether the particle is transmitted or reflected at the end of its stay, and pointer of our Larmor clock is not the spin but the total angular momentum. -- Highlights: ► The idea of a Larmor clock is reexamined in the relativistic regime. ► We propose a concept of proper time for quantum theoretical particles. ► The Larmor clock measures the passage of this quantum theoretical proper time.

  10. Telling time

    Directory of Open Access Journals (Sweden)

    2002-06-01

    Full Text Available According to Einstein’s renowned declaration, for those who believe in physics – or, more precisely, in its capability to offer a “scientific” representation of the world – the distinction between present, past and future is just “an illusion, though obstinate”. If we consider an effective analogy by Mauro Dorato, we can state that those who agree with the famous German scientist will recognize in the present, past and future a relationship very similar to that between “here” and “somewhere else” – in other words, the present is just a located moment and has no privileged status. In other conceptual universes, some of which are explored by philosophy, or imagined by art, as well as in other scientific disciplines like biology, the need for a strong distinction between “what has happened”, “what will happen” and “what is happening” seems to be unavoidable. At the macroscopic level of living beings there does not seem to be a way out of the “eternal present”, which cannot be escaped even by the desire of some well-developed mammals to understand reality or such an apparently primary experience as the “passing of time”. Even the “timeless” description of reality offered by physics is immersed in time and changes with it. This paradox seems to contain the core of the irreducibility between two cultural constructions which we will be calling “the time of the soul” and “the time of the world”, after Ricoeur. The main thesis of this essay is that there are two fundamentally different ways of facing the mystery of time, which have a precise relationship with the mentioned contrast between the subjective and the objective conception of time – mental, qualitative and experienced in the first case; physical, quantitative and measurable in the second. Considering Ricoeur’s research on time and stories, we can conclude that this dichotomy may give rise to another similarly radical difference between

At a quantum level, this view of change as relative variation leads to a fundamentally timeless formalism for quantum gravity. Here, we will show how one may avoid this acute 'problem of time'. Under our view, duration is still regarded as relative, but te...

    The ‘Cloud’, hailed as a new digital commons, a utopia of collaborative expression and constant connection, actually constitutes a strategy of vitalist post-hegemonic power, which moves to dominate immanently and intensively, organizing our affective political involvements, instituting new modes of enclosure, and, crucially, colonizing the future through a new temporality of control. The virtual is often claimed as a realm of invention through which capitalism might be cracked, but it is precisely here that power now thrives. Cloud time, in service of security and profit, assumes all is knowable. We bear witness to the collapse of both past and future virtuals into a present dedicated to the exploitation of the spectres of both.

    Once convicted, the perpetrator of serious crime embarks upon a new journey: the challenge of adjusting to long-term imprisonment. Prisoners’ views of incarceration and the meaning of this experience may affect their later adjustment to life in the community. On the basis of brief narrative responses collected during an epidemiological survey of the psychological health of prisoners in France, this study examined the impact of incarceration on psychological state in a group of 59 inmates serving long sentences. Qualitative content analysis and computer-assisted linguistic analysis (using ALCESTE software) were performed on the textual data of open responses to three standard questions. Using a combination of these two approaches, seven categories of the subjective experience of prisoners in the sample were identified: the Outside World, Others, Punishment, Time, Affects and Impulses, Self-Concept, and Speech. Further qualitative analyses were then performed to compare the responses of Severely Mentally Ill (SMI) subjects and subjects with no psychiatric disorder. These analyses revealed contrasting attitudes towards incarceration. SMI subjects spoke in more hostile and persecutory terms about their experience in prison, attributing suffering to external circumstances, while subjects with no psychiatric disorder evoked similar themes, but with an introspective attitude. The themes evoked by mentally ill individuals in our sample suggest that their reactions to the prison environment arise in part from aspects of their psychiatric symptoms, and this may have relevance to future mental health policy and practices in criminal corrections.

    When space (time) translation symmetry is spontaneously broken, the space crystal (time crystal) forms; when permittivity and permeability periodically vary with space (time), the photonic crystal (photonic time crystal) forms. We proposed the concept of photonic time crystal and rewritten the Maxwell's equations. Utilizing Finite Difference Time Domain (FDTD) method, we simulated electromagnetic wave propagation in photonic time crystal and photonic space-time crystal, the simulation results show that more intensive scatter fields can obtained in photonic time crystal and photonic space-time crystal.

  1. Gap timing and the spectral timing model.

    A hypothesized mechanism underlying gap timing was implemented in the Spectral Timing Model [Grossberg, S., Schmajuk, N., 1989. Neural dynamics of adaptive timing and temporal discrimination during associative learning. Neural Netw. 2, 79-102] , a neural network timing model. The activation of the network nodes was made to decay in the absence of the timed signal, causing the model to shift its peak response time in a fashion similar to that shown in animal subjects. The model was then able to accurately simulate a parametric study of gap timing [Cabeza de Vaca, S., Brown, B., Hemmes, N., 1994. Internal clock and memory processes in aminal timing. J. Exp. Psychol.: Anim. Behav. Process. 20 (2), 184-198]. The addition of a memory decay process appears to produce the correct pattern of results in both Scalar Expectancy Theory models and in the Spectral Timing Model, and the fact that the same process should be effective in two such disparate models argues strongly that process reflects a true aspect of animal cognition.

  4. Choosing between his time and her time?

    Deding, Mette; Lausten, Mette

    When adding up market work and non-market work, Danish men and women work about the same number of hours per day. While men do the major share of the market work, women do the major share of the non-market work. In this paper, we investigate the interaction between the different time use activities...... spouses. This is especially the case for market work and housework, while childcare is different. Thus, when considering labour supply the total workload must be taken into account. Furthermore, the interdependence between the spouses’ working hours suggests that bargaining is taking place...... for Danish working couples. The analysis is based on the Danish Time Use Survey from 2001, which contains detailed time use information for both spouses. We analyse the time used by each spouse on market work and non-market work, taking the endogeneity of time regressors into account. Non-market work...

  5. Time crystals: a review

    Time crystals are time-periodic self-organized structures postulated by Frank Wilczek in 2012. While the original concept was strongly criticized, it stimulated at the same time an intensive research leading to propositions and experimental verifications of discrete (or Floquet) time crystals—the structures that appear in the time domain due to spontaneous breaking of discrete time translation symmetry. The struggle to observe discrete time crystals is reviewed here together with propositions that generalize this concept introducing condensed matter like physics in the time domain. We shall also revisit the original Wilczek’s idea and review strategies aimed at spontaneous breaking of continuous time translation symmetry.

  12. The World Congress of Paediatric Cardiology and Cardiac Surgery: a short factual history by Jane Somerville.

    2012-12-01

    The World Congress of Paediatric Cardiology and Cardiac Surgery has survived with minimal assets and simple organisation. Each congress is special, taking on the humour, flavour, and culture of the organising country. It is hard work for a few organisers and money is hard to raise. The steering committee works closely, fairly, and successfully, and even though accused of being secretive and effete that does not matter. It is efficient and produces successful, happy world congresses, where all involved with the speciality are welcome. With so many "grown-ups" with congenital heart disease, it is no longer just a paediatric problem - maybe the name of this congress must change again. Regardless, the flag must fly on.

  13. The Wandering Jew in Novels of Jane Austen: The Pursuit of an Organic Whole in Romanticism

    Directory of Open Access Journals (Sweden)

    Rebecca Kenseh Madaki

    2014-09-01

    Full Text Available Austen’s fictions may or may not set out to express the framework of imagery that projects the division of beings into four levels as enumerated by Northrop Frye in his Essay “The drunken boat: the revolutionary element in Romanticism”, her works, like the Romanticism poets are greatly influenced by this framework. This framework is found in the imagery of pre- Romanticism poetry and is the basis for the conflict between the Romanticism and the pre-Romanticism one despite their affiliation and similarities. Frye expounds the influence of this framework in the poetic garden of imagery in Romanticism, this work attempts to expand the influence in the prose garden of Austen’s symbolic expressions. Austen uses symbolism to interpret the structure of beings and their station, the concept of alienation, the journey, and the quest and finally the formation of an organic whole; the superb inter-change of the masculine and feminine domain in metaphoric representation excels Austen’s works within Romanticism expressions.

    2017-12-01

    Full Text Available The aim of my article will be that of discussing a recent transformation of the novel by the American writer Seth Grahame-Smith: his gothic adaptation Pride and Prejudice and Zombies (2009. This version is not just inspired by the Romantic novelist, but it keeps up a dialogue and a constant reference to her, captivating the readers into a constant confrontation between past and present, tradition and innovation, conventions and subversion, seriousness and satire. This new product is an interesting example of literary remediation of the original Pride and Prejudice, created to engage the contemporary audience to copy and interact with a challenging society, which, far from being stable and rational, is scary and full of mystery.

  16. Conversation, characterisation and corpus linguistics: Dialogue in Jane Austen’s Sense and Sensibility

    Directory of Open Access Journals (Sweden)

    E.H. Hubbard

    2002-08-01

    Full Text Available This article reports on a corpus-based exploration of the role that fictional dialogue plays in characterisation. The focus is on the two main characters of Austen’s Sense and Sensibility and (a the extent to which certain features of their dialogue can be said to tie in with general perceptions that Elinor represents the “sense” and Marianne the “sensibility” of the novel’s title; and (b the extent to which Austen can be said to have exploited these features to enable the sisters to speak with subtly differing voices. The features themselves were drawn from two linguistic frameworks, namely cohesion in text linguistics (specifically, the category of conjunctive cohesion as originated by Halliday and Hasan (1976, and the category of “involvement” in register analysis (most prominently, Biber 1988. The density of these features in each dialogue was calculated, compared statistically and salient differences considered in relation to the focal issues of the study. Although two of the five hypotheses formulated were not supported, the results overall provided strong indications that Austen successfully distinguishes between the sisters through their dialogue, and often in ways that link with less subtle, more explicit cues to their character that are given in the text. The study thus reveals how certain text-linguistic and register features can underpin characterisation in fiction, and in so doing explicates aspects of what it is that readers and literary critics respond to when they comment on characterisation in a novel.

    Full Text Available By analyzing data from 102 million mortgage loan applications in the US between 2004–2012 (about 90% of all applications across 3,141 counties and 8,000 financial institutions, we investigate whether applicants’ gender matters in the bank's lending decision. We find evidence that female applicants face a higher rejection rate than males, holding all else constant. Similar results are obtained for Hispanic applicants compared to non-Hispanics, and minorities compared to non-minorities. Moreover, we document that this discrimination is pro-cyclical (i.e. peaks in recessions and that it varies substantially across states. Most importantly, we show that non-economic factors help explain the variation in discrimination across states while economic factors do not. Specifically, we find that gender discrimination in lending is higher in states with (i high level of conservatism, (ii low support for gay rights, and (iii low female representation in the state legislature (JEL E32, G21, J16.
