  1. Use of MELANIE

    International Nuclear Information System (INIS)

    Lanfranchi, M.

    1987-09-01

    MELANIE allows to calculate, with a minimum of simple instructions, the transport of neutrons and gammas in slab, spherical and cylindrical geometry. MELANIE has several libraries of microscopic group cross sections. The preparation of macroscopic cross sections is trivial whatever is number of groups, energy regions, order of developments of Legendre, etc. Geometry and sources are defined through elementary instructions which permit the choice of continuous or discrete spectrum, independently of the group structure. The transport calculation is done by well-known codes, e.g. ANISN and SURCU, for which MELANIE manages the input and output. Input to MELANIE is elementary because the code defines, instead of the user, the best choice of parameters and appropriate options. Adequate commands permit to modify them if necessary. MELANIE is enclosed by peripheral programs which permit to obtain information such as fluxes in different energy regions, doses, heat production, etc., in form of tables and graphs. The version MELANIE 7 described here is built in the system RSYST. An independent version is in preparation. MELANIE permits to save time for preparation of input. Its great flexibility of input and output makes it a modern code. 1 ref., 1 tab

    Erna was one of the child patients treated by Melanie Klein in Berlin, employing her recently discovered play technique. Since Erna died in Chile, the authors considered the IPA Congress in Santiago an opportunity to present a paper as a homage both to Erna and, especially, to Klein. She learned much from that very disturbed child, which she later used to sustain the ongoing development of her theories. The paper explores biographic data relevant to understanding both the case and the theories. It analyses the case material to follow Klein in the discovery and the handling of the child's transference and the harsh expressions of hate, jealousy and envy, which are brought in, with sad consequences, by strong persecutory feelings. Klein's comparison of this case with that of Freud's Wolf-man is also considered, mostly to show that the similarities were less than originally claimed, and that Klein, perhaps, was introducing a theoretic shift which led her technique to gradually change from 'Nachträglichkeit' to the 'signification-resignification' pair, akin to Strachey's concept of the mutative interpretation. Lastly, the comprehension of Erna's strong psychotic traits and the links with later developments of the theory on psychosis are studied.

    Objective To describe the redactions in contemporary protocols for industry-sponsored randomised drug trials with patient relevant outcomes and to evaluate whether there was a legitimate rationale for the redactions. Design Cohort study. Under the Freedom of Information Act, we requested access to trial protocols approved by a research ethics committee in Denmark from October 2012 to March 2013. We received 17 consecutive protocols, which had been redacted before we got them, and nine protocols without redactions. In five additional cases, the companies refused to let the committees give us access, and in three other cases, documents were missing. Participants Not applicable. Setting Not applicable. Main outcome measure Amount and nature of redactions in 22 predefined key protocol variables. Results The redactions were most widespread in those sections of the protocol where there is empirical evidence of substantial problems with the trustworthiness of published drug trials: data analysis, handling of missing data, detection and analysis of adverse events, definition of the outcomes, interim analyses and premature termination of the study, sponsor's access to incoming data while the study is running, ownership to the data and investigators' publication rights. The parts of the text that were redacted differed widely, both between companies and within the same company. Conclusions We could not identify any legitimate rationale for the redactions. The current mistrust in industry-sponsored drug trials can only change if the industry offers unconditional access to its trial protocols and other relevant documents and data.

  6. Melanie Klein's metapsychology: phenomenological and mechanistic perspective.

    Science.gov (United States)

    Mackay, N

    1981-01-01

    Freud's metapsychology is the subject of an important debate. This is over whether psychoanalysis is best construed as a science of the natural science type or as a special human science. The same debate applies to Melanie Klein's work. In Klein's metapsychology are two different and incompatible models of explanation. One is taken over from Freud's structural theory and appears to be similarly mechanistic. The other is clinically based and phenomenological. These two are discussed with special reference to the concepts of "phantasy" and "internal object".

    We developed an expert system to analyze and interpret protein maps. This system, Melanie (medical electrophoresis analysis interactive expert), can distinguish between normal and cirrhotic liver and identify various types of cancer on the basis of protein patterns in biopsy specimens. Our findings suggest that some diseases associated with toxic compounds or modifications of the human genome can be diagnosed by expert systems that analyze protein maps. The combination of protein mapping and computer analysis could result in a clinically useful "molecular scanner". The massive amount of information analyzed and stored in such studies requires new strategies, including centralized databases and image transmission over networks. Increased understanding of protein expression and regulation will enhance the importance of the human genome project in medicine and biology.

    With the prevalence of video recordings from smart phones, dash cams, body cams, and conventional surveillance cameras, privacy protection has become a major concern, especially in light of legislation such as the Freedom of Information Act. Video redaction is used to obfuscate sensitive and personally identifiable information. Today's typical workflow involves simple detection, tracking, and manual intervention. Automated methods rely on accurate detection mechanisms being paired with robust tracking methods across the video sequence to ensure the redaction of all sensitive information while minimizing spurious obfuscations. Recent studies have explored the use of convolution neural networks and recurrent neural networks for object detection and tracking. The present paper reviews the redaction problem and compares a few state-of-the-art detection, tracking, and obfuscation methods as they relate to redaction. The comparison introduces an evaluation metric that is specific to video redaction performance. The metric can be evaluated in a manner that allows balancing the penalty for false negatives and false positives according to the needs of particular application, thereby assisting in the selection of component methods and their associated hyperparameters such that the redacted video has fewer frames that require manual review.

  9. Melanie Klein on mourning: Its relation to pastoral care.

    1991-09-01

    This paper connects the work of Melanie Klein on mourning to the pastor's work with the grief sufferer. Klein holds that mourning is an illness of manic depressive character rooted in infantile development. Klein's description of manic defenses in the face of loss has adult behavioral analogues with which the pastor must deal to bring mourning to resolution.

  11. Melanie Klein and countertransference: a note on some archival material.

    Hinshelwood, R D

    2008-01-01

    Five pages of notes were found in the Melanie Klein Archives at the Wellcome Library that concern her views on countertransference in 1953. Because of the paucity of references to countertransference in Klein's published writings these Notes fill in out knowledge. Her views were provoked by the work her students were doing in their experimental analyses of schizophrenic patients. Apocryphal stories suggest that Klein remained aligned with Freud's view of countertransference as simply interference. The Notes confirm that, whilst there is some truth to that, she did have a more sophisticated and nuanced view of the unconscious relations between analyst and analysand.

  12. [An unpublished contribution of Melanie Klein "On Reassurance"].

    2005-01-01

    Melanie Klein's unpublished paper on reassurance is presented in German translation. The author shows that it was a contribution to Glover's investigation on psychoanalytic technique in the 1930s. The paper is discussed against the background of the technical discussions conducted in London at that time (e. g. M. Schmideberg, J. Strachey) and of Klein's relevant publications. Although Klein consistently considered "correct" interpretation to be the most effective means of reassurance, she occasionally also accepted a non-interpreting approach. In this respect the paper presented here goes further than any other of her writings.

  13. Melanie Klein's letters addressed to Marcelle Spira (1955-1960).

    2009-12-01

    Between 1955 and 1960, Melanie Klein wrote some 45 hitherto unpublished letters to Marcelle Spira, the Swiss psychoanalyst living at that time in Geneva. In 2006, after Spira's death, these letters were deposited with the Raymond de Saussure Psychoanalysis Centre in Geneva. They are the only known letters that Klein addressed to her psychoanalyst colleagues. Several topics are mentioned in them: (1) the meetings between the two women in Geneva and London; (2) Spira's contribution to Boulanger's translation into French of The Psychoanalysis of Children, which Klein herself carefully revised; (3) the papers that Klein was at that time working on, including Envy and Gratitude; (4) Spira's own work; (5) the difficulties that Spira, a Kleinian psychoanalyst who trained in Buenos Aires, was encountering in her attempt to be admitted to the Swiss Psychoanalytical Society; and (6) a few items of personal and family news. In addition to the invaluable historical information that these letters provide, they offer us a very moving epistolary self-portrait of Melanie Klein, enabling us to discover her personality in the final years of her life - she died in September 1960, just two months after writing her last letter to Spira.

  14. The conflict and process theory of Melanie Klein.

    Science.gov (United States)

    Kavaler-Adler, S

    1993-09-01

    This article depicts the theory of Melanie Klein in both its conflict and process dimensions. In addition, it outlines Klein's strategic place in psychoanalytic history and in psychoanalytic theory formation. Her major contributions are seen in light of their clinical imperatives, and aspects of her metapsychology that seem negligible are differentiated from these clinical imperatives. Klein's role as a dialectical fulcrum between drive and object relations theories is explicated. Within the conflict theory, drive derivatives of sex and aggression are reformulated as object-related passions of love and hate. The process dimensions of Klein's theory are outlined in terms of dialectical increments of depressive position process as it alternates with regressive paranoid-schizoid-position mental phenomenology. The mourning process as a developmental process is particularly high-lighted in terms of self-integrative progression within the working through of the depressive position.

  15. A new look at the theory of Melanie Klein.

    Science.gov (United States)

    Stein, R

    1990-01-01

    This paper tried to show that Melanie Klein's theory can very profitably be viewed as a descriptive theory of strong emotions rather than an instinct or developmental theory. Furthermore, since in Klein's thinking feelings 'create' objects, the primacy of feelings in this theory is central. The paper contains a short chronological study of Klein's formulations of psychic phenomena in terms of affects. It is also maintained that the paranoid-schizoid and the depressive positions are constellations of affects and of reactions to them; that psychic development is essentially in terms of the capacity to tolerate feelings, and that the basic conflict in mental life is between feelings of love and hate and associated feelings. Such a view solves many of the conceptual difficulties of Kleinian theory and in addition promises rewarding insights into the world of feelings.

  16. Some developments from the work of Melanie Klein.

    Spillius, E B

    1983-01-01

    This paper discusses four areas of work in which several followers of Melanie Klein in Britain have developed some of the discoveries and ideas she initiated. First, extension of her concept of projective identification is briefly described, with emphasis on Bion's and Rosenfeld's stress on its communicative as well as its pathological aspects. Second, the extension of Klein's ideas about the epistemophilic instinct, on symbolism, and about projective identification is described in the work of Segal, Bion, Money-Kyrle, and Bick on the development of the capacity to think. Third, certain developments in Kleinian technique are described, with emphasis on the use of the concept of projective identification in analysing transference, and on the analysis of acting out in the transference, a trend contributed to by many Kleinian analysts but perhaps most closely associated with Betty Joseph. Finally, continued refinements in the analysis of the death instinct are briefly described, together with discussion of the changes these refinements have led to in ideas about the organization and relations of parts of the self and internal objects.

  17. Primitive object love in Melanie Klein's thinking; early theoretical influences.

    Science.gov (United States)

    Likierman, M

    1993-04-01

    Melanie Klein's thinking on early object love is pivotal to her vision of development. Yet within her texts it is often enmeshed in complex formulations that obscure its full significance. A greater clarity in viewing Klein's concept of early object love is achieved through tracing some of its historical origins. The author notes that it was inspired by aspects of Ferenczi's theory, hence its similarities with the concept of 'primary love' formulated by another of Ferenczi's analysands, Michael Balint. Ferenczi's thinking on the subject formed part of a broader network of theoretical developments in the history of psychoanalytic ideas. These are shown to have origins in Freud's fluctuations between a 'passive' and a 'genital' characterisation of infantile sexuality. A dialectical tension between these two possibilities, as maintained in the Freudian texts, was partly embodied in the differing outlooks of Klein's two psychoanalysts, Abraham and Ferenczi. The author suggests that it is a mixture of their approaches that partly shaped Klein's thinking on the earliest experiences of love. After outlining these developments the author analyses the nature of early object love as it emerges from Klein's powerful, if intermittent descriptions in the texts. The analysis also tackles a textual ambiguity in Klein's formulations, showing that she explored two kinds of primitive ideal experience without explicitly differentiating them. Such differentiation is important inasmuch as it highlights negative and positive aspects of Kleinian theory at root.

    In the occasion of the celebrations for the 150th anniversary of the founding of Italy (1861-2011), it was decided to analyse the artwork "The Italian Flag" (La Bandiera Italiana) created by the artist Fernando Melani (Pistoia, 1907-1985), one of the precursors of the Poor Art artistic movement in Italy. This project is a follow-up to a previous study which was mainly focused on the pigments and dyes found in his home-studio. The main goal of this paper is to identify a correct diagnostic plan, based on the use of a combination of non-invasive and micro-invasive methodologies, in order to determine the state of preservation and define the best conservation procedures for a contemporary artwork. Visible, infrared and infrared false colour images as well as the Fibre Optic Reflectance Spectroscopy (FORS) technique were applied in situ to analyse The Italian Flag. Laser Induced Breakdown Spectroscopy (LIBS), Fourier Transform Infrared (FT-IR) and micro-Raman spectroscopies, Pyrolysis-Gas Chromatography/Mass Spectroscopy (Py-GC/MS), High Performance Liquid Chromatography with Diode Arrays Detection (HPLC-DAD) and Mass Spectrometric Detection (HPLC-ESI-Q-ToF) were all applied to three small samples detached from the three painted (green-blue, white and red-yellow, respectively) areas of the flag. The combination of the data obtained with all these techniques made possible a comprehensive understanding of both the chemical composition and physical behaviour of the materials used by the artist and supported curators in defining the preventive conservation of this artwork.

  4. The Treatise on Names from the Nomocanon (Kormchaia of the Kirillo-Belozersk Redaction

    Elena V. Belyakova

    2013-12-01

    Full Text Available This article for the first time publishes the Treatise on Names from the little known redaction of the nomocanon (Kormchaia. In the Treatise the unknown author protests against the widespread use of non-Christian names in his time, such as Tomilo, Shumilo, etc., and he says that it is unacceptable for a Christian to have any name other than the one he received at baptism. He allows adding to the name only some indications of a person’s trade, his fatherland or place of origin. In this article the author analyzes the manuscript tradition of the Kirillo-Belozersk redaction that occurred no later than the first quarter of the 17th century. The redaction is the shortened text of the Canon norms of the Daniil’s redaction. Thus its composition is expanded by sections addressing real-life problems, such as: icons painted by “infidels,” unrighteous wealth, and impious names. The paper also examines the issue of the attribution of the titles of this version, which historians formerly had ascribed to Maximus the Greek.

  5. Melanie Klein and Anna Freud: the discourse of the early dispute.

    Science.gov (United States)

    Viner, R

    1996-01-01

    Divisions in the field of the psychoanalysis of children can be traced to a dispute over the infantile super-ego between the theorists Melanie Klein and Anna Freud beginning in 1927. These divisions are understood within the analytic world as the result of scientific disputation between alternative valid theories. An examination of the language, claims, and epistemology of Klein's and Freud's publications in 1927 that marked the public commencement of the conflict, reveals a personalized discourse in which authority was derived from the allegiance, experience, and personal analytic standing of the contestants as much as from theoretical insight. The structure and rhetoric of the debate suggest that, rather than terminating the dispute, the publications of 1927 served to encourage professionalization in child analysis and establish Anna Freud and Melanie Klein as authoritative alternative theorists.

  6. THE PSYCHOANALYTIC CONTRIBUTIONS OF MELITTA SCHMIDEBERG KLEIN. MORE THAN MELANIE KLEIN'S REBEL DAUGHTER.

    Cassullo, Gabriele

    2016-03-01

    Compared to the impact of the work of Melanie Klein on the history of psychoanalysis, the contributions of her daughter, Melitta Schmideberg, passed almost unnoticed. At present, Schmideberg is solely remembered for having harshly attacked her mother at the start of the Controversial Discussions of the British Psycho-Analytical Society and for having coined the fitting expression "stable instability" in order to describe borderline and asocial personality disorders. However, the author discusses how the early groundbreaking discoveries of Klein with regards to primitive anxieties were the result of the joint work and thinking of Melanie and Melitta. Moreover, he argues that the conflict between the two, along with the subsequent polarization of their views, did not facilitate the development of psychoanalysis, neither did it help the analytic community to recognize the value of Melitta's contributions to psychoanalysis.

  7. Theories on anxiety in Freud and Melanie Klein. Their metapsychological status.

    De Bianchedi, E T; Scalozub De Boschan, L; De Cortiñas, L P; De Piccolo, E G

    1988-01-01

    This paper presents a comparative study of the theories on anxiety formulated by Freud and Melanie Klein, with particular emphasis on the questions of its origin, its meaning for the individual and its function in both theoretical systems. The purpose of this comparative analysis is to offer an instrument which helps frame the theoretical discussions in psychoanalysis in an epistemological context. The authors hold that for Freud anxiety is considered as one more amongst the various manifestations of mental life, which his general theories try to explain, whereas for Melanie Klein anxiety and its destinies occupies a central place in her theories on mental functioning. The differences in both theories, which the authors of this paper describe, especially as to origin, function and meaning of anxiety, respond partially to the different metapsychological points of view with which both authors focus mental life--points of view which they have themselves investigated in a previous paper.

    The goals of the MELANIE project are to determine if disease-associated patterns can be detected in high resolution two-dimensional polyacrylamide gel electrophoresis (HR 2D-PAGE) images and if a diagnosis can be established automatically by computer. The ELSIE/MELANIE system is a set of computer programs which automatically detect, quantify, and compare protein spots shown on HR 2D-PAGE images. Classification programs help the physician to find disease-associated patterns from a given set of two-dimensional gel electrophoresis images and to form diagnostic rules. Prototype expert systems that use these rules to establish a diagnosis from new HR 2D-PAGE images have been developed. They successfully diagnosed cirrhosis of the liver and were able to distinguish a variety of cancer types from biopsies known to be cancerous.

    A comprehensive understanding of both the chemical composition and physical behaviour of modern materials is an important consideration in devising correct conservation treatments for contemporary artworks. To this end, national and international research projects and networks have been established that deal mainly with the preservation, conservation, and understanding of materials used by contemporary artists. This paper focuses on the self-taught artist Fernando Melani (1907-1985), one of the precursors of the Poor Art artistic movement in Italy, and for the first time provides a scientific viewpoint on the artist's materials and works. The analyses, which mainly focus on the pigments/dyes found in his home-studio, were carried out primarily by using Fourier Transform Infrared Spectroscopy (FT-IR) and ultraviolet, visible, and near-infrared Fibre Optic Reflectance Spectroscopy (UV-Vis-NIR FORS). This paper emphasises the performance of FT-IR and FORS in the identification of contemporary artistic materials, since these two techniques have been found to produce highly complementary data. The use of both of these was required in order to obtain a comprehensive understanding of the composition of Melani's materials. Furthermore, one of his artworks, named by Melani himself with its inventory number N. Inv. 2625 (1981), was investigated in situ with the sole use of the FORS technique. The results showed that Melani used traditional inorganic pigments as well as modern organic dyes. Calcite and barite were used as fillers and extenders. Sulphur and abrasive powder were also found, thus confirming his use of a large variety of non-conventional artists' materials.

It attempts to highlight the reciprocity of the relationship between Melanie Klein and other members of that Society by showing how the climate of psychoanalytical opinion that was prevalent among members of that Society during the first decade of her stay in London, and which encouraged discussion of clinical work and interest in psychoanalytical discovery, provided a congenial setting for her to become firmly established as an active member of the British Society and to continue her contributions to psychoanalytic theory and clinical expertise. The paper also traces the development of Melanie Klein's main theoretical contributions, together with relevant criticisms of them as they emerged, against the background of the history of the British Psycho-Analytical Society. It describes the controversies that arose as to whether or not her ideas could properly be viewed within the framework of psychoanalytic theory, as formulated by Freud, and the attempted resolution of these controversies, together with some comments on the repercussions of these theoretical disagreements on relationships within the Society. An extensive list of references is included to facilitate a more detailed study of the subject.

    Full Text Available Essa pesquisa aborda o tema 'neurose obsessiva' na obra de Melanie Klein. Assim, foi possível estudar um panorama histórico da construção do pensamento dessa autora - tendo em vista que seguimos um itinerário cronológico de seus textos - e, como consequência importante, obter uma dimensão epistemológica dessa construção. Isso porque a neurose obsessiva constitui-se como um destacado elemento organizador da obra de Klein, sobretudo nas décadas de 1920 e 1930, período que marcou o atendimento dos primeiros pacientes da autora que, em sua maioria, eram crianças que sofriam de neurose obsessiva.The obsessive neurosis from Melanie Klein's optic. This research focuses on obsessive neurosis in Melanie Klein's. Thus, it was also possible to study a historical broad view of the construction of this author's thought, having in mind that a chronological itinerary was followed, and, as an important consequence, an epistemological dimension of this construction was obtained. This was so because the obsessive neurosis constitutes an outstanding organizing element in Klein's work, mainly in the 1920's and 30's. This time was marked by the observation of the author's first patients, who were, in their majority, children suffering from obsessive neurosis.

  16. Between practice and theory: Melanie Klein, Anna Freud and the development of child analysis.

    Science.gov (United States)

    Donaldson, G

    1996-04-01

    An examination of the early history of child analysis in the writings of Melanie Klein and Anna Freud reveals how two different and opposing approaches to child analysis arose at the same time. The two methods of child analysis are rooted in a differential emphasis on psychoanalytic theory and practice. The Kleinian method derives from the application of technique while the Anna Freudian method is driven by theory. Furthermore, by holding to the Freudian theory of child development Anna Freud was forced to limit the scope of child analysis, while Klein's application of Freudian practice has led to new discoveries about the development of the infant psyche.

  17. Vicious circles of punishment: a reading of Melanie Klein's Envy and gratitude.

    Science.gov (United States)

    Smith, Henry F

    2008-01-01

    Staged as a moral drama, Melanie Klein's Envy and Gratitude (1957) straddles two eras: one reflecting a simpler more concrete, historical method, and the other an approach of greater complexity, focused on the transferential moment. Embedded within the transference are the vicious circles of envy and punishment that are the hallmark of Klein's text. Punishment itself which is always punishment of both self and other, creates its own vicious circle, set in motion by a single act. In the sadomasochistic enactments that result, the moral force of Klein's categories fuels the countertransference. A detailed clinical hour is presented.

  19. Quantitative comparison and evaluation of two commercially available, two-dimensional electrophoresis image analysis software packages, Z3 and Melanie.

    While a variety of software packages are available for analyzing two-dimensional electrophoresis (2-DE) gel images, no comparisons between these packages have been published, making it difficult for end users to determine which package would best meet their needs. The goal here was to develop a set of tests to quantitatively evaluate and then compare two software packages, Melanie 3.0 and Z3, in three of the fundamental steps involved in 2-DE image analysis: (i) spot detection, (ii) gel matching, and (iii) spot quantitation. To test spot detection capability, automatically detected protein spots were compared to manually counted, "real" protein spots. Spot matching efficiency was determined by comparing distorted (both geometrically and nongeometrically) gel images with undistorted original images, and quantitation tests were performed on artificial gels with spots of varying Gaussian volumes. In spot detection tests, Z3 performed better than Melanie 3.0 and required minimal user intervention to detect approximately 89% of the actual protein spots and relatively few extraneous spots. Results from gel matching tests depended on the type of image distortion used. For geometric distortions, Z3 performed better than Melanie 3.0, matching 99% of the spots, even for extreme distortions. For nongeometrical distortions, both Z3 and Melanie 3.0 required user intervention and performed comparably, matching 95% of the spots. In spot quantitation tests, both Z3 and Melanie 3.0 predicted spot volumes relatively well for spot ratios less than 1:6. For higher ratios, Melanie 3.0 did much better. In summary, results suggest Z3 requires less user intervention than Melanie 3.0, thus simplifying differential comparison of 2-DE gel images. Melanie 3.0, however, offers many more optional tools for image editing, spot detection, data reporting and statistical analysis than Z3. All image files used for these tests and updated information on the software are available on the internet

It is argued that part of the reason for the incorporation of the main redaction in Q (here Kloppenborg� s Q2 + Q3 was to defend the Judean ethnic identity of the Q people.� This becomes evident in its conservative approach to the Law as opposed to that of the formative stratum where the Law was freely reconstructed. Q� s approach to the Law is also informed by its Moses/New Exodus typology encountered in the various strata.

  2. An analysis of redactions in Canada's Common Drug Review Clinical Review Reports and how they relate to the patients' voice.

    2017-09-11

    Canada's Common Drug Review (CDR) evaluates drug data from published and unpublished research, as well as input from patient groups, to recommend provincial coverage. Currently, the CDR process gives manufacturers the opportunity to redact information in the final publicly available report. Patients often have strong feelings regarding the efficacy, harms, health-related quality of life (HRQL), and cost associated with the drugs under review and their redacted data. Highlighting Canada's approach will hopefully build on the growing international concern regarding transparency of clinical study data. The purpose was to objectively examine and classify completed, publicly available CDR-Clinical Review Reports (CRR) for redactions, and compare them to the patients' reported interests as patient-centred outcomes. Two independent reviewers searched for and examined publicly available CDR-CRR from November 2013-September 2016 through the Canadian Agency for Drugs and Technologies in Health (CADTH) on-line database. Both reviewers separately classified the redactions and patient-reported interests into the following categories: efficacy, harms, HRQL and costs. All discrepancies were rectified by consensus involving a third reviewer. Fifty-two completed CDR-CRR were reviewed. 48 (92%) included patient-reported interests and 40 (77%) had redactions classified in the following categories: efficacy (75%), costs (48%), harms (38%), HRQL (23%). 89% of redactions were outcomes identified as patient-reported interests (69% efficacy, 42% harms, 36% cost, 33% HRQL). When examining drug characteristics, biological agents were statistically associated with increased odds of redactions with respect to either efficacy (OR 3.4, 95% CI 1.0 to 11.6) or harms (OR 3.5, 95% CI 1.02 to 12.4) compared with non-biological agents. Whether data from the CDR-CRR used in the decision-making should be fully disclosed to the public is controversial. Our findings suggest clinical data (efficacy

  3. Good and Bad: Love and Intimacy From Plato to Melanie Klein.

    Science.gov (United States)

    Stromberg, David

    2018-06-01

    Melanie Klein's theories on love outline a complex system of relations-an oscillating dynamic of psychical and emotional tendencies following from both actual experience and fantasies produced by the mind. Her insights are often discussed and applied in psychoanalytical contexts, but the philosophical implications of her theory-especially in relation to Platonic thought-have rarely been discussed. In this article, I will attempt to address this gap by setting out some preliminary yet core considerations shared by both Plato and Klein. First, I will describe some structural parallels between Kleinian and Platonic thought, especially in dialectical terms. Second, I will outline Plato's covert influence on Freud as passing through the teachings of philosopher Franz Brentano. And last, I will discuss intimacy as a struggle between the forces of good and bad, creativity and destruction, and love and hate-suggesting that Klein's conception of love emerges as a moral exigency.

  4. Some observations on hallucination: clinical application of some developments of Melanie Klein's work.

    Taylor, D

    1983-01-01

    The analysis of a psychotic patient is used to illustrate the importance of certain developments of Melanie Klein's work. The case presentation focuses upon the formal qualities of the patient's communications, many of which were amalgamations of profoundly incompatible elements, particularly a subtle destructiveness which parasitized seemingly impartial reports about her state of mind. These communications embodied important object relationships. The patient used her communications to conjure up psychic disintegration. As a result of her involvement in 'chuntering' her preoccupations would become increasingly violent, cruel and sexualized. The patient's equivocal communications generate confusion. This is central to the patient's experience of self-destruction as persecution. A number of ideas are advanced concerning the origins of the patient's hallucinations. These include her relish at the introduction of sensory distortions. Questions are raised about the nature of certain types of hallucination, the origins and intractability of concrete thinking, about verbalization and about the typology of psychotic patients.

  5. Off the Charts: Medical documentation and selective redaction in the age of transparency.

    2018-01-01

    A growing demand for transparency in medicine has the potential to strain the doctor-patient relationship. While information can empower patients, unrestricted patient access to the electronic medical record may have unintended consequences. Medical documentation is often written in language that is inaccessible to people without medical training, and without guidance, patients have no way to interpret the constellation of acronyms, diagnoses, treatments, impressions, and arguments that appear throughout their own chart. Additionally, full transparency may not allow physicians the intellectual or clinical freedom they need to authentically express questions, problematic impressions, and concerns about the patient's clinical and psychosocial issues. This article examines the ethical challenges of transparency in the digital era and suggests that selective redaction may serve as a means to maintain transparency, affirm physician's discretion, and uphold the core values of the doctor-patient relationship amidst disruptive technological change.

  6. ‘Cut in two’, Part 2: Reconsidering the redaction of Q 12:42−46

    Llewellyn Howes

    2015-06-01

    Full Text Available In his influential 1987 monograph, Kloppenborg identified three layers in the Sayings Gospel Q: the ‘formative stratum’ (or Q¹, the ‘main redaction’ (or Q², and the ‘final recension’ (or Q³. He ascribed the cluster of sayings in Q 12:39–59 to the main redaction. Within this cluster appears the parable of the loyal and wise slave (Q 12:42–46. In my view, some portions of this parable actually originate with the formative stratum. The aim of the current article is to reconsider the redactional make-up of this parable by appealing to Kloppenborg’s own criteria for distinguishing between Q1 and Q2, including those of ‘characteristic forms’, ‘characteristic motifs’ and ‘implied audience’.

  7. Block selective redaction for minimizing loss during de-identification of burned in text in irreversibly compressed JPEG medical images.

    Clunie, David A; Gebow, Dan

    2015-01-01

    Deidentification of medical images requires attention to both header information as well as the pixel data itself, in which burned-in text may be present. If the pixel data to be deidentified is stored in a compressed form, traditionally it is decompressed, identifying text is redacted, and if necessary, pixel data are recompressed. Decompression without recompression may result in images of excessive or intractable size. Recompression with an irreversible scheme is undesirable because it may cause additional loss in the diagnostically relevant regions of the images. The irreversible (lossy) JPEG compression scheme works on small blocks of the image independently, hence, redaction can selectively be confined only to those blocks containing identifying text, leaving all other blocks unchanged. An open source implementation of selective redaction and a demonstration of its applicability to multiframe color ultrasound images is described. The process can be applied either to standalone JPEG images or JPEG bit streams encapsulated in other formats, which in the case of medical images, is usually DICOM.

  8. The Struggle of Integration: James Baldwin and Melanie Klein in the Context of Black Lives Matter

    2016-12-01

    Full Text Available Recent killings of unarmed black citizens are a fresh reminder of the troubled state of racial integration in the United States. At the same time, the unfolding Black Lives Matter protest movements and the responses by federal agencies each testify to a not insignificant capacity for addressing social pathologies surrounding the color line. In order to respond to this ambivalent situation, this article suggests a pairing between the work of James Baldwin and that of the psychoanalyst Melanie Klein. I will argue that we cannot fully appreciate the depths of what Baldwin called the “savage paradox” of race without the insights provided by Klein and object relations psychoanalysis. Conversely, Baldwin helps us to sound out the political significance of object relations approaches, including the work of Klein and those influenced by her such as Hanna Segal and Wilfred Bion. In conversation with the work of Baldwin, object relations theory can help to identify particular social settings and institutions that might allow concrete efforts toward racial justice to take root.

    Eskom and the University of Fort Hare are engaged in a biomass gasification project using the System Johansson Biomass gasifier (SJBG). The SJBG installed at Melani village in the Eastern Cape province of South Africa is used to assess the viability and affordability of biomass gasification in South Africa. A community needs assessment study was undertaken at the village before the installation of the plant. The study revealed the need for low-cost electricity for small businesses including growing of crops, chicken broilers, manufacturing of windows and door frames, sewing of clothing, bakery etc. It was also found that the community had a problem with the socio-environmental aspects of burning biomass waste from the sawmill furnace as a means of waste management. The SJBG uses the excess biomass materials (waste) to generate low-cost electricity to drive community economic development initiatives. A study on the properties and suitability of the biomass materials resulting from sawmill operation and their suitability for gasification using the SJBG was undertaken. The study established that the biomass materials meet the requirements for the SJBG. A 300 Nm{sup 3}/h SJBG was then manufactured and installed at the village. (author)

  10. The origins of disquieting discoveries by Melanie Klein: the possible significance of the case of 'Erna'.

    Science.gov (United States)

    Frank, C; Weiss, H

    1996-12-01

    Using the example of the analysis of 6-year-old Erna, which extended over more than two years and was the longest treatment conducted by Melanie Klein in her Berlin years, the authors demonstrate the importance of her early child analyses for the development of some of her concepts and hence for a decisive advance in psychoanalysis itself. For this purpose they adduce unpublished original documents found among Klein's papers in London, which include autobiographical material, the text of her Würzburg lecture on her obsessional-neurotic little patient, handwritten session notes, and drawings by Erna herself. Although in the author's view Klein attempted to accommodate her findings within Freud's theoretical framework, her clinical experience of the psychic reality of the relational world of early oedipality eventually called for the introduction of new concepts. The combined parent figure, primary sadism, the paranoid-schizoid position, splitting, the relevance of the death drive to the superego, and later formulations on reparation, envy and gratitude are all shown to be foreshadowed in Klein's account of the treatment of Erna. After some retrospective considerations of Erna's analysis and a fleeting glimpse of Erna as an adult, the authors conclude by emphasising the significance of Klein's emigration to England for the subsequent flowering of her work.

  12. Patronage in the dispute over child analysis between Melanie Klein and Anna Freud--1927-1932.

    Science.gov (United States)

    Aguayo, J

    2000-08-01

    The author investigates the role of patrons and advocates for Melanie Klein's clinical ideas at the British Psycho-Analytical Society against the backdrop of her theoretical and technical differences with Anna Freud from 1927 to 1932. He also outlines the development of Klein and Anna Freud's theories and techniques within the nascent discipline of child psychoanalysis. The London and Viennese patrons/advocates contributed to polarising what initially were clinical differences about how to analyse pre-latency and latency-age children and which technical processes might best facilitate successful treatment. While the author speculates that a diversity of motivations and agendas may have driven the London group's support for Klein--personal and politicised enthusiasm (Jones), genuine conviction (Riviere) and attempts at theoretical rapprochement between the London and Vienna schools (Glover)--he also argues that Freud's diagnosis with cancer in 1923 and suspicion of patricidal son-successors necessitated the choice of a female successor with unquestioning loyalty to his doctrines. From 1932, when Klein's clinical authority was established, her first group of English supporters began to splinter, as she went on to become a training analyst, mentor and patron in her own right to a succeeding generation of adherents who defended her views during the Controversial Discussions.

  13. Melanie Klein and Repression: an examination of some unpublished Notes of 1934.

    Science.gov (United States)

    Hinshelwood, R D

    2006-01-01

    Fifteen pages of unpublished Notes were found in the Melanie Klein Archives dating from early 1934, a crucial moment in Klein's development. She was at this time, 1934, moving away from child analysis, whilst also rethinking and revising her allegiance to Karl Abraham's theory of the phases of libidinal development. These Notes, entitled "Early Repression Mechanism," show Klein struggling to develop what became her characteristic theories of the depressive position and the paranoid-schizoid position. Although these Notes are precursors of the paper Klein gave later to the IPA Congress in 1934, they also show the origins of the emphasis she and her followers eventually gave to "splitting" rather than repression. The Notes give us an insight into the way that she worked clinically at the time. We see Klein's confidence develop as she diverged from the classical theories and technique. Her ideas were based on close attention to the detail of her clinical material, rather than attacking theoretical problems directly. The Notes show her method of struggling to her own conclusions, and they offer us a chance to grasp the roots of the subsequent controversy over Kleinian thought.

    1997-12-01

    After two generations of software systems for the analysis of two-dimensional electrophoresis (2-DE) images, a third generation of such software packages has recently emerged that combines state-of-the-art graphical user interfaces with comprehensive spot data analysis capabilities. A key characteristic common to most of these software packages is that many of their tools are implementations of algorithms that resulted from research areas such as image processing, vision, artificial intelligence or machine learning. This article presents the main algorithms implemented in the Melanie II 2-D PAGE software package. The applications of these algorithms, embodied as the feature of the program, are explained in an accompanying article (R. D. Appel et al.; Electrophoresis 1997, 18, 2724-2734).

    2014-10-01

    Full Text Available The Matthean redaction of Mark 7:30 in Matthew 15:28 often receives scant attention in scholarship in terms of its narrative quality. At most, it is regarded as a truncation of the full Marcan version, while all attention is given to Matthew’s introduction of the notion of ‘faith’ in this verse. This article argues, by contrast, and on the basis of a synoptic comparison and narratological analysis of both texts, that more justice is done to both versions of the conclusion of this healing miracle when understanding them as achieving different narrative effects, with Matthew focusing on the immediacy of the healing, while Mark creates suspense, thus focusing on the veracity of Jesus’ statement that the girl in question is healed.

Batu 55, Tangerine cv. Pontianak and Lime cv. Nimas propagated by grafting. The result showed the percentage of successful grafting ranged between 37.5% to 100%, while the percentage of the shoot formed on grafted plants was 75%-100%. The use of Poncirus trifoliata as interstock has stimulated fastest bud break on Tangerine cv. Pontianak in just 24.75 days while the Troyer citrange has stimulated better shoot growth in Lime cv. Nimas, resulted to the highest shoot around 52.20 cm which was significantly different from other treatments. Meanwhile, Carizzo citrange has been found to have some influences to the plant diameter and the number of leave of Lime cv. Nimas but showed insignificant effect on the growth of its own diameter. The use of interstock showed that it can be used to promote the growth of scion which usually has slow growth when it is directly grafted on the rootstock.

Dem europäischen/französischen Mann und Krieger wird der orientalische Mann als multivalentes und kulturell unterlegenes Wesen gegenübergestellt. Bei aller Subtilität der Kunst handelt es sich im Kern um die Gegenüberstellung von Stereotypen. Ulz kann in ihrer Studie überzeugend den sexuierten Subtext des Orientalismus nachweisen.Napoleon’s Campaign of Egypt at the end of the 18th century had afterwards been worked with and addressed in graphical media extensively. Melanie Ulz analyzes these media in respect to expressed as well as changing concepts of masculinity. The visualizations essentially display what has later been called “Orientalism”. The European/ French man and warrior is opposed to the Oriental man, who is depicted as multivalent and culturally inferior. Despite the subtlety of the art, the works basically deal with the opposition of stereotypes. Ulz manages to convincingly prove the sexualized subtext of Orientalism.

    Full Text Available fMRI studies showed that acupuncture could induce hemodynamic changes in brain networks. Many of these studies focused on whether specific acupoints could activate specific brain regions and were often limited to manual acupuncture at acupoints on the limbs. In this fMRI study, we investigated acupuncture's modulation effects on brain functional networks by electroacupuncture (EA at acupoints on the midline of abdomen. Acupoints Guanyuan (CV4 and Zhongwan (CV12 were stimulated in 21 healthy volunteers. The needling sensations, brain activation, and functional connectivity were studied. We found that the limbic-prefrontal functional network was deactivated by EA at CV4 and CV12. More importantly, the local functional connectivity was significantly changed during EA stimulation, and the change persisted during the period after the stimulation. Although minor differences existed, both acupoints similarly modulated the limbic-prefrontal functional network, which is overlapped with the functional circuits associated with emotional and cognitive regulation.

  6. THE STUDY AND TREATMENT OF MOTHERS AND INFANTS, THEN AND NOW: MELANIE KLEIN'S "NOTES ON BABY" IN A CONTEMPORARY PSYCHOANALYTIC CONTEXT.

    Aguayo, Joseph; Salomonsson, Björn

    2017-04-01

    This paper draws on Melanie Klein's (unpublished) observational notes of her infant grandson, written primarily in 1938 and 1939. Apart from moving glimpses into a young family's life, the notes contain astute observations of an infant's behavior and emotions. Compared with Klein's published writings, the style is less theoretical and polemical. Later, in his latency years, Klein's grandson was in analysis with Marion Milner, who in 1952 published a paper drawing on the treatment. The present paper focuses on (1) how observations and treatment of the same child and his family by clinicians in close relationships with each other (Klein, Milner, and Winnicott) fertilized reciprocal influence but also brought into question the validity of Klein's observations, and (2) the relative merits and contributions of various modalities in understanding the infant's psyche, including experimental research, direct observation, parent-infant psychotherapy, and reconstructions from older patients-as occurs, for example, in psychoanalysis. © 2017 The Psychoanalytic Quarterly, Inc.

  7. CV controls from design to operation

    2002-01-01

    The cooling and Ventilation (CV) group has emphasised the need to redefine its organisational structure at the end of 98. The main objective of this operation was to ensure the CV group to be more competitive and efficient through the growing tasks of the LHC projects. The main evolution given to this reorganisation is that the new structure is more project oriented and then operates on three distinct axes: Design, Work and Operation. Process control project management requires a complete and early interaction and participation of all the actors involved. This procedure to be efficient and constructive must be considered and performed not only during the design stage but along the project planning phases and must go beyond the completion work including the process control operation activity. The paper explains the present project management for process control. It describes the present constraints and gives suggestions to a different approach to these projects to improve performances and efficiency of a contr...

  8. EARTH, MOON, SUN, AND CV ACCRETION DISKS

    2009-01-01

    Net tidal torque by the secondary on a misaligned accretion disk, like the net tidal torque by the Moon and the Sun on the equatorial bulge of the spinning and tilted Earth, is suggested by others to be a source to retrograde precession in non-magnetic, accreting cataclysmic variable (CV) dwarf novae (DN) systems that show negative superhumps in their light curves. We investigate this idea in this work. We generate a generic theoretical expression for retrograde precession in spinning disks that are misaligned with the orbital plane. Our generic theoretical expression matches that which describes the retrograde precession of Earths' equinoxes. By making appropriate assumptions, we reduce our generic theoretical expression to those generated by others, or to those used by others, to describe retrograde precession in protostellar, protoplanetary, X-ray binary, non-magnetic CV DN, quasar, and black hole systems. We find that spinning, tilted CV DN systems cannot be described by a precessing ring or by a precessing rigid disk. We find that differential rotation and effects on the disk by the accretion stream must be addressed. Our analysis indicates that the best description of a retrogradely precessing spinning, tilted, CV DN accretion disk is a differentially rotating, tilted disk with an attached rotating, tilted ring located near the innermost disk annuli. In agreement with the observations and numerical simulations by others, we find that our numerically simulated CV DN accretion disks retrogradely precess as a unit. Our final, reduced expression for retrograde precession agrees well with our numerical simulation results and with selective observational systems that seem to have main-sequence secondaries. Our results suggest that a major source to retrograde precession is tidal torques like that by the Moon and the Sun on the Earth. In addition, these tidal torques should be common to a variety of systems where one member is spinning and tilted, regardless if

    2003-01-01

    During the next three years, the ST/CV group will be deeply involved in the installation works for the LHC project. During this period the need for maintenance activity will decrease. The minimum level will be reached during the “long shutdown” of the PS and SPS machines in 2005. The budget for the maintenance will decrease accordingly, thus the CV group had to review its maintenance strategy. The new contract, which started on January 1st 2003, has been defined to cope with these workload variations during the next years and to guarantee the minimum maintenance activity on the existing equipment. A lump-sum contract based on a win-win strategy has been discarded. The contractor no longer has to guarantee the performance of the CERN cooling and ventilation systems. A new price list strategy based on performance indicators and penalties has been chosen. The contractor now has to guarantee the performance of every maintenance operation demanded by CERN. This modification obliged the Operation section of the...

    Full Text Available Garfield produces a critique of minimalist art practice by demonstrating how the artist Melanie Jackson’s Some things you are not allowed to send around the world (2003 and 2006 and the experimental film-maker Vivienne Dick’s Liberty’s booty (1980 – neither of which can be said to be about feeling ‘at home’ in the world, be it as a resident or as a nomad – examine global humanity through multi-positionality, excess and contingency, and thereby begin to articulate a new cosmopolitan relationship with the local – or, rather, with many different localities – in one and the same maximalist sweep of the work. ‘Maximalism’ in Garfield’s coinage signifies an excessive overloading (through editing, collage, and the sheer density of the range of the material that enables the viewer to insert themselves into the narrative of the work. In the art of both Jackson and Dick Garfield detects a refusal to know or to judge the world; instead, there is an attempt to incorporate the complexities of its full range into the singular vision of the work, challenging the viewer to identify what is at stake.

  13. IJ-OpenCV: Combining ImageJ and OpenCV for processing images in biomedicine.

    Science.gov (United States)

    Domínguez, César; Heras, Jónathan; Pascual, Vico

    2017-05-01

    The effective processing of biomedical images usually requires the interoperability of diverse software tools that have different aims but are complementary. The goal of this work is to develop a bridge to connect two of those tools: ImageJ, a program for image analysis in life sciences, and OpenCV, a computer vision and machine learning library. Based on a thorough analysis of ImageJ and OpenCV, we detected the features of these systems that could be enhanced, and developed a library to combine both tools, taking advantage of the strengths of each system. The library was implemented on top of the SciJava converter framework. We also provide a methodology to use this library. We have developed the publicly available library IJ-OpenCV that can be employed to create applications combining features from both ImageJ and OpenCV. From the perspective of ImageJ developers, they can use IJ-OpenCV to easily create plugins that use any functionality provided by the OpenCV library and explore different alternatives. From the perspective of OpenCV developers, this library provides a link to the ImageJ graphical user interface and all its features to handle regions of interest. The IJ-OpenCV library bridges the gap between ImageJ and OpenCV, allowing the connection and the cooperation of these two systems. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Apple is one of the important fruit in Iran. according to respiration and ethylene production behaviors, apple classified as a climacteric fruit. Therefore, any treatments, which can inhibit or prevent the action of ethylene, they can increase the postharvest life of horticultural production. 1-methylcyclopropane (1-MCP is one of the chemical which is environmental save and use as a very small concentrations. In this experiment, the effects of 1-MCP at concentrations of 0 (as a control, 0.25, 0.5, 0.75 and 1 µl.l-1 were used in apple cv. "Golab Kohanz", a land race fruits which is cultivated from long times ago in Iran. After the 1-MCP treatment, they were moved to cold room at 2 ºC and RH of ca 90% for 60 days. Samples were removed from the cold room and analysis for physicochemical characteristics. "Golab Kohanz" apples treated with 1-MCP showed improved fruit firmness, titratable acidity (TA, and total soluble solid after 147 days at 2ºC , compared to the control non-treated fruits. Also, treatment with 1-MCP significantly reduced the incidence of superficial scald in "Golab Kohanze". In general, 1-MCP-treated apples delay ripening during storing in cold room and increased shelf life. Overall, the results indicate that 1-MCP has tremendous potential for maintaining apple quality during storage and post storage.

    Although two-dimensional electrophoresis (2-DE) computer analysis software packages have existed ever since 2-DE technology was developed, it is only now that the hardware and software technology allows large-scale studies to be performed on low-cost personal computers or workstations, and that setting up a 2-DE computer analysis system in a small laboratory is no longer considered a luxury. After a first attempt in the seventies and early eighties to develop 2-DE analysis software systems on hardware that had poor or even no graphical capabilities, followed in the late eighties by a wave of innovative software developments that were possible thanks to new graphical interface standards such as XWindows, a third generation of 2-DE analysis software packages has now come to maturity. It can be run on a variety of low-cost, general-purpose personal computers, thus making the purchase of a 2-DE analysis system easily attainable for even the smallest laboratory that is involved in proteome research. Melanie II 2-D PAGE, developed at the University Hospital of Geneva, is such a third-generation software system for 2-DE analysis. Based on unique image processing algorithms, this user-friendly object-oriented software package runs on multiple platforms, including Unix, MS-Windows 95 and NT, and Power Macintosh. It provides efficient spot detection and quantitation, state-of-the-art image comparison, statistical data analysis facilities, and is Internet-ready. Linked to proteome databases such as those available on the World Wide Web, it represents a valuable tool for the "Virtual Lab" of the post-genome area.

    We investigate the design of anonymous voting protocols, CV-based binary-valued ballot and CV-based multi-valued ballot with continuous variables (CV) in a multi-dimensional quantum cryptosystem to ensure the security of voting procedure and data privacy. The quantum entangled states are employed in the continuous variable quantum system to carry the voting information and assist information transmission, which takes the advantage of the GHZ-like states in terms of improving the utilization of quantum states by decreasing the number of required quantum states. It provides a potential approach to achieve the efficient quantum anonymous voting with high transmission security, especially in large-scale votes. (paper)

    2018-02-16

    A routine of light or moderate alcohol consumption (≤1 drink/day for women and 1 to 2 drinks/day for men) is associated with a lower risk for all-cause mortality, coronary artery disease (CAD), type 2 diabetes mellitus (T2D), heart failure (HF), and stroke. Conversely, heavy drinking, (>4 drinks/day) is associated with an increased risk for death and cardiovascular (CV) disease (CVD). Excessive alcohol intake trails behind only smoking and obesity among the 3 leading causes of premature deaths in the United States (US). Heavy alcohol use is a common cause of reversible hypertension (HTN), nonischemic dilated cardiomyopathy, atrial fibrillation (AF), and stroke (both ischemic and hemorrhagic). Among males aged 15 to 59 years, alcohol abuse is perhaps the leading cause of premature death. As such, the risk-to-benefit ratio of drinking is less favorable in younger individuals. A daily habit of light to moderate drinking is ideal for those who choose to consume alcohol regularly. Red wine in particular before or during the evening meal is linked with the best long-term CV outcomes. Most of the studies on alcohol and health are observational, and correlation does not prove causation. Health care professionals should not advise nondrinkers to begin drinking because of the paucity of randomized outcome data coupled with the potential for alcohol abuse even among seemingly low risk individuals.

    This research was conducted in order to study the occurrence of mutation on irradiated plantlets and their resistance of plants of banana cv. Ambon Kuning against Fusarium wilt. Plantlets of banana cv. Ambon Kuning sized 5 cm were exposed to gamma rays at the doses 5 - 35 Gy intervals, then were subcultured for obtained M 1 V 5 plantlets. More over, the planlets were acclimatized and were planted in the field was already infected by Fasarium (f).culbense (FOC). The result indicated that irradiated plantlets of the doses 20 - 35 Gy were not able to survive up to 6 months after exposing to gamma rays. Abnormalities of M 1 V 5 plantlets originated from irradiated plantlets at the doses 10 and 15 Gy were shown on rossette plantlets with rigid and dark green leaves, and the formation of smooth mass morphologically shaped like calculus. The appearance of plant height and number of suckers of suckers of M 1 V 5 plants in the field was quite various. The number of survival plants after 8 moths planting was 8, 7, 15, and 28, respectively originated from untreated plants and irradiated plantlets at the doses 5, 10, and 15 Gy. After one year planting , only 2 plants were able to survive from irradiated plantlet at the dose 15 Gy. The plants could produce 27 plantlets obtained from culturing their shoot tips. Further study of these plantlets was needed in order create the stability of their resistance to FOC. (author)

    Dormant buds of mango (Mangifera indica L. cv. Langra) exposed to acute gamma-irradiation dosages of 1.0, 2.0, 3.0, 4.0, 5.0 and 6.0 kiloroentgens (kR), were grafted on to one-year-old seedling stock. Dosages of 2.0 and 3.0 kR were found satisfactory for the purpose, as measured by bud lethality and scion growth. A bud graft from 3.0 kR bore fruits of excellent quality. Compared with the control, the fruits were heavier, larger and had more creamish-yellow pulp. None of the other morphological changes expressed by the mutant fruits, observed over three fruiting seasons, were disadvantageous. The tree habit is being further investigated before the mutant can be considered for release as an improved cultivar. (author)

    Full Text Available The high perishability of papaya (Carica papaya L. reduces its lifespan as well as limits marketing. Coating the fruits is an alternative to aid food preservation. We aimed to evaluate the effects of coating propolis extract on the physicochemical characteristics of papaya stored at room temperature. Solo papayas cv. 'Golden' were randomly divided into five postharvest treatment groups, three forms of dip-coating (70% alcohol, hydroalcoholic extract of propolis to 2.5%, and hydroalcoholic extract of propolis to 5% and two controls (one uncoated and one with refrigerated uncoated fruits. The weight loss, firmness, soluble solids (SS, titratable acidity (TA, SS/TA, and hydrogen potential (pH were evaluated at the intervals of 4 days every 12th storage day. Sensory analysis was performed on the 4th day of storage of papayas and evaluated by untrained through the acceptance testing. Treatments “refrigerated”, “propolis 2.5%”, and “5% propolis” presented with the lowest weight loss. The firmness level for treatment propolis 5% was superior to that of control, alcohol, and 2.5% propolis treatments. The SS was greater for propolis 5% treatment, which only differed from the alcohol treatment. The TA and SS/TA did not vary with the treatments, but with the storage time. The pH of refrigerated papaya showed significant differences in relation to other treatments. The fruits subjected to refrigerated treatment presented with chilling injury. Papayas coated with propolis extract showed sensory acceptability similar to that in other treatments on the 4th day of storage. The coating of propolis extract is a promising alternative for the control of weight loss and for the maintenance of firmness in Solo papaya cv. 'Golden'.

  9. Core Problem: Does the CV Parent Body Magnetization require differentiation?

    2016-12-01

    Evidence for the presence of past dynamos from magnetic studies of meteorites can provide key information on the nature and evolution of parent bodies. However, the suggestion of a past core dynamo for the CV parent body based on the study of the Allende meteorite has led to a paradox: a core dynamo requires differentiation, evidence for which is missing in the meteorite record. The key parameter used to distinguish core dynamo versus external field mechanisms is absolute field paleointensity, with high values (>>1 μT) favoring the former. Here we explore the fundamental requirements for absolute field intensity measurement in the Allende meteorite: single domain grains that are non-interacting. Magnetic hysteresis and directional data define strong magnetic interactions, negating a standard interpretation of paleointensity measurements in terms of absolute paleofield values. The Allende low field magnetic susceptibility is dominated by magnetite and FeNi grains, whereas the magnetic remanence is carried by an iron sulfide whose remanence-carrying capacity increases with laboratory cycling at constant field values, indicating reordering. The iron sulfide and FeNi grains are in close proximity, providing mineralogical context for interactions. We interpret the magnetization of Allende to record the intense early solar wind with metal-sulfide interactions amplifying the field, giving the false impression of a higher field value in some prior studies. An undifferentiated CV parent body is thus compatible with Allende's magnetization. Early solar wind magnetization should be the null hypothesis for evaluating the source of magnetization for chondrites and other meteorites.

    Full Text Available Abstract The quality of forage production is a prerequisite to raising livestock. Therefore, income losses in this activity, primarily cattle raising, can result in the impossibility of economic activity. Through the qualitative and quantitative anatomical study of Urochloa hybrida cv. Mulato II and U. brizantha cv. Marandu, we searched for descriptions and compared changes in the individual vegetative body from populations with death syndrome pastures (DPS. Specimens were collected at different physiological stages from farms in northern Mato Grosso. After collection, the individuals were fixed in FAA50 and stored in 70% alcohol. Histological slides were prepared from the middle third of the sections of roots, rhizomes, and leaves, and the proportions and characteristics of tissues were evaluated in healthy, intermediate, and advanced stages of DPS. Changes were compared between cultivars. With the advancement of the syndrome, the following changes were observed: a more marked decrease in the length of roots in U. hybrida; disorganization of the cortical region of the roots and rhizome cultivars; fungal hyphae in roots and aerenchyma formation in U. hybrida; a decrease in sclerenchyma fiber proportions in roots and leaves; sclerification of the epidermis of U. brizantha rhizomes; and an increase in pericyclic fibers in U. hybrida. Furthermore, there was a decrease in the volume of epidermal cells of the abaxial face of the leaves of both cultivars, with a greater reduction in U. hybrida; a gradual decrease in thickness in the midrib of leaves similar to leaf mesophyll; conduction system obstructions; partial or total cell lysis in roots and rhizomes affected by the syndrome. Obstructions in sieve tube element and companion cells, and sometimes obstruction in xylem vessel elements. The evolution of DPS in cultivars was similar, but there were variations, arising probably from the physiological response to stress, such as aerenchyma formation in

    Full Text Available The objective was to evaluate the effect of nitrogen fertilization on the establishment of forage peanut (Arachis pintoi cv. Belmonte propagated vegetatively. The experiment was conducted in a greenhouse in a completely randomized design with treatments arranged in a 2 × 4 factorial design - two ages (70 and 85 days after planting and four nitrogen doses (0, 40, 80 and 120 kg/ha - with four replications. Morphogenetic and structural characteristics and production were evaluated. The nitrogen accelerated the establishment of the forage peanut with an increase in dry weight of green leaves and stolons. The greatest length of stolons (48.0 cm was obtained with a dose equivalent to 86 kg N/ha and higher density of stolons (20 stolons/vase between 78 and 82 kg N/ha. Nitrogen fertilization also reduced the phyllochron from 6.7 to 4.6 days/leaf. These data were more intense at 85 days, suggesting greater photosynthetic contribution during this period related to the large number of leaves after 70 days. Therefore, nitrogen can be an important tool to accelerate the establishment of pure stands of forage peanut.

    2013-09-01

    Accurate and fast detection of infrared (IR) dim target has very important meaning for infrared precise guidance, early warning, video surveillance, etc. In this paper, some basic principles and the implementing flow charts of a series of algorithms for target detection are described. These algorithms are traditional two-frame difference method, improved three-frame difference method, background estimate and frame difference fusion method, and building background with neighborhood mean method. On the foundation of above works, an infrared target detection software platform which is developed by OpenCV and MFC is introduced. Three kinds of tracking algorithms are integrated in this software. In order to explain the software clearly, the framework and the function are described in this paper. At last, the experiments are performed for some real-life IR images. The whole algorithm implementing processes and results are analyzed, and those algorithms for detection targets are evaluated from the two aspects of subjective and objective. The results prove that the proposed method has satisfying detection effectiveness and robustness. Meanwhile, it has high detection efficiency and can be used for real-time detection.

    International Nuclear Information System (INIS)

    Rittmann, P.D.

    1984-08-01

    Several user-oriented programs for the Hewlett-Packard HP-41CV are explained. The first program builds, stores, alters, and ages a list of radionuclides. This program only handles single- and double-decay chains. The second program performs convenient conversions for the six nuclides of concern in plutonium handling. The conversions are between mass, activity, and weight percents of the isotopes. The source can be aged and/or neutron generation rates can be computed. The third program is a timekeeping program that improves the process of manually estimating and tracking personnel exposure during high dose rate tasks by replacing the pencil, paper, and stopwatch method. This program requires a time module. The remaining four programs deal with computations of time-integrated air concentrations at various distances from an airborne release. Building wake effects, source depletion by ground deposition, and sector averaging can all be included in the final printout of the X/Q - Hanford and X/Q - Pasquill programs. The shorter versions of these, H/Q and P/Q, compute centerline or sector-averaged values and include a subroutine to facilitate dose estimation by entering dose factors and quantities released. The horizontal and vertical dispersion parameters in the Pasquill-Gifford programs were modeled with simple, two-parameter functions that agreed very well with the usual textbook graphs. 8 references, 7 appendices

    CERN Document Server

    Poulsen, S

    2008-01-01

    In modern data centres, it is an emerging trend to operate and manage computers as software components or logical resources and not as physical machines. This technique is known as â€ワvirtualisation” and the new computers are referred to as â€ワvirtual machines” (VMs). Multiple VMs can be consolidated on a single hardware platform and managed in ways that are not possible with physical machines. However, this is not yet widely practiced for control system deployment. In TS-CV, a collection of VMs or a â€ワvirtual infrastructure” is installed since 2005 for SCADA systems, PLC program development, and alarm transmission. This makes it possible to consolidate distributed, heterogeneous operating systems and applications on a limited number of standardised high-performance servers in the Central Control Room (CCR). More generally, virtualisation assists in offering continuous computing services for controls and maintaining performance and assuring quality. Implementing our systems in a vi...

    Diabetes and cancer are a major global public health problem. Plant-derived agents with undesirable side-effects were required. This study aimed to evaluate antidiabetic and anticancer activities of the ethanolic leaf extract of Mangifera indica cv. Okrong and its active phytochemical compound, mangiferin. Antidiabetic activities against yeast α-glucosidase and rat intestinal α-glucosidase were determined using 1 mM of p-nitro phenyl-α-D-glucopyranoside as substrate. Inhibitory activity against porcine pancreatic α-amylase was performed using 1 mM of 2-chloro-4 nitrophenol-α-D-maltotroside-3 as substrate. Nitrophenol product was spectrophotometrically measured at 405 nm. Anticancer activity was evaluated against five human cancer cell lines compared to two human normal cell lines using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Mango leaf extract and mangiferin exhibited dose-dependent inhibition against yeast α-glucosidase with the IC50 of 0.0503 and 0.5813 mg/ml, respectively, against rat α-glucosidase with the IC50 of 1.4528 and 0.4333 mg/ml, respectively, compared to acarbose with the IC50 of 11.9285 and 0.4493 mg/ml, respectively. For anticancer activity, mango leaf extract, at ≥200 μg/ml showed cytotoxic potential against all tested cancer cell lines. In conclusion, mango leaf possessed antidiabetic and anticancer potential in vitro. PMID:28217550

    Lettuce (Lactuca sativa, L.) is an important annual plant of the family Asteraceae (Compositae). The commercial lettuce cultivar Tizian has been used in various scientific studies investigating the interaction of the plant with phytopathogens or biological control agents. Here, we present the de novo draft genome sequencing and gene prediction for this specific cultivar derived from transcriptome sequence data. The assembled scaffolds amount to a size of 2.22 Gb. Based on RNAseq data, 31,112 transcript isoforms were identified. Functional predictions for these transcripts were determined within the GenDBE annotation platform. Comparison with the cv. Salinas reference genome revealed a high degree of sequence similarity on genome and transcriptome levels, with an average amino acid identity of 99%. Furthermore, it was observed that two large regions are either missing or are highly divergent within the cv. Tizian genome compared to cv. Salinas. One of these regions covers the major resistance complex 1 region of cv. Salinas. The cv. Tizian draft genome sequence provides a valuable resource for future functional and transcriptome analyses focused on this lettuce cultivar. Copyright © 2017 Elsevier B.V. All rights reserved.

    A novel cyclovirus, CyCV-VN, was recently identified in cerebrospinal fluid (CSF) from patients with central nervous system (CNS) infections in central and southern Vietnam. To explore the geographic distribution of this novel virus, more than 600 CSF specimens from patients with suspected CNS infections in northern Vietnam, Cambodia, Nepal and The Netherlands were screened for the presence of CyCV-VN but all were negative. Sequence comparison and phylogenetic analysis between CyCV-VN and another novel cyclovirus recently identified in CSF from Malawian patients indicated that these represent distinct cycloviral species, albeit phylogenetically closely related. The data suggest that CyCV-VN has a limited geographic distribution within southern and central Vietnam. Further research is needed to determine the global distribution and diversity of cycloviruses and importantly their possible association with human disease.

    Full Text Available This work aims to investigate biofuels for diesel engines produced on a lab-scale from the fresh water microalgae Chlorella vulgaris (FWM-CV. The impact of growing conditions on the properties of biodiesel produced from FWM-CV was evaluated. The properties of FWM-CV biodiesel were found to be within the ASTM standards for biodiesel. Due to the limited amount of biodiesel produced on the lab-scale, the biomass of dry cells of FWM-CV was used to yield emulsified water fuel. The preparation of emulsion fuel with and without FWM-CV cells was conducted using ultrasound to overcome the problems of large size microalgae colonies and to form homogenized emulsions. The emulsified water fuels, prepared using ultrasound, were found to be stable and the size of FWM-CV colonies were effectively reduced to pass through the engine nozzle safely. Engine tests at 3670 rpm were conducted using three fuels: cottonseed biodiesel CS-B100, emulsified cottonseed biodiesel water fuel, water and emulsifier (CS-E20 and emulsified water containing FWM-CV cells CS-ME20. The results showed that the brake specific fuel consumption (BSFC was increased by about 41% when the engine was fueled with emulsified water fuels compared to CS-B100. The engine power, exhaust gas temperature, NOx and CO2 were significantly lower than that produced by CS-B100. The CS-ME20 produced higher power than CS-E20 due to the heating value improvement as a result of adding FWM-CV cells to the fuel.

    Cotesia vestalis (Haliday) is an endoparasitoid of Plutella xylostella (L.) larvae and injects a polydnavirus (CvBV) into its host during oviposition. In this report we describe the characterization of a gene (CvBV805) and its products. CvBV805 is located on the segment S8 of CvBV genome; it has a size of 909 bp and encodes a predicted protein of 125 amino acids. This protein contains an ankyrin repeat domain with a high degree of similarity with IκB-like genes. Gene transcripts were detected in extracts of the host as early as 2 h post-parasitization (p.p.) and continued to be detected through 24 h. Tissue-specific expression patterns showed that CvBV805 might be involved in early host immunosuppression. CvBV805 was detected in parasitized hosts at 12 h p.p. and in rBac-eGFP-CvBV805-infected Tn-5B1-4 cells at 72 h.p.i. by using western blots analysis. The size of the protein expressed in the host hemocytes and infected Tn-5B1-4 cells was 17 kDa and 56 kDa (including eGFP), respectively, which nearly corresponded with the predicted molecular weight (14.31 kDa) of CvBV805, suggesting that the protein did not undergo extensive post-translational modification. The protein was confirmed to be present within the nuclear region in hemocytes of the parasitized P. xylostella larvae at 48 h p.p. using confocal laser scanning microscopy

    Torreya grandis cv. Merrillii, a tertiary survival plant, is a rare tree species of significant economic value and expands rapidly in China. Its special habitat factor analysis has the potential value to provide guide information for its planting, management, and sustainable development, because the suitable growth conditions for this tree species are special and strict. In this paper, the special habitat factors for T. grandis cv. Merrillii in its core region, i.e., in seven villages of Zhuji City, Zhejiang Province were analyzed with Principal Component Analysis (PCA) and a series of data, such as IKONOS image, Digital Elevation Model (DEM), and field survey data supported by the spatial information technology. The results showed that T. grandis cv. Merrillii exhibited high selectivity of environmental factors such as elevation, slope, and aspect. 96.22% of T. grandis cv. Merrillii trees were located at the elevation from 300 to 600 m, 97.52% of them were found to present on the areas whose slope was less than 300, and 74.43% of them distributed on sunny and half-sunny slopes. The results of PCA analysis indicated that the main environmental factors affecting the habitat of T. grandis cv. Merrillii were moisture, heat, and soil nutrients, and moisture might be one of the most important ecological factors for T. grandis cv. Merrillii due to the unique biological and ecological characteristics of the tree species.

    iča, that is to say through a series of svetosavski redaction of their painting program. With the newly recorded analogies, and considered for the first time in this context, discovered by the author of this text in the painting programs of other representative foundations of the Nemanjićs’ from the 13th century, the circumstances are now present which will diminish, if not eliminate, the uncertainties related to the identity of the said monks, and also, to the extent possible today shed light on the problem spot in the Mileševa narthex program. It was concluded that the numerous, and doubtlessly interesting Mileševa series of holy monks did not exclude the significant group of famous monks - poets, who, among the chosen maximalists of Orthodox religion and personal ideals of St. Sava himself, could be ‘recognized’ not only in the churches whose painting program was certainly designed by the same person, but also in those being in the care of the ones respecting and continuing Sava’s work. Painted within a certain larger whole, constituted of individual figures of holy monks, they had a much stronger influence on the iconographic programs of the most important Serbian churches in 13th century than the one attributed to it by the recent ideas on the tradition of that epoch. The standard pattern was created in the old narthex of the archiepiscopal church in Žiča. The issue here is the new interpretation of the interesting and barely older solution from the Studenica southern vestibule choir loft. The painting program of both churches was under supervision of St. Sava himself; however, the mentioned Žiča example was painted over at the beginning of 14th century. Not deviating from the principal pattern applied in Žiča, the chosen holy poets in the Mileševa narthex could also represent some sort of counterpart to the figures of the most prominent hermits, founders and leading figures of desert monks with which they shared the zone. The new observations

    To summarize the regularity of application of Lianquan (CV 23) in clinical practice in Chinese ancient times through analysis of ancient traditional Chinese medical (TCM) literature. A total of 60 books involving CV 23 from the 1 156 ancient TCM books listed in the fifth edition of Encyclopedia of Traditional Chinese Medicine were collected by using CV 23 as the main keyword and "Sheben" "Benchi", and "Jieben" (the other names of CV 23 in TCM)as the supplementary keywords and analyzed systematically. A database was then constructed from the collected data, including the related types of disorders or symptoms, acupoint recipes, and methods of needling and moxibustion, contraindications, etc. A total of 196 articles related to the application of CV 23 from 60 ancient classical books were collected in accordance with the inclusive criteria. Among them, 155 articles are referred to the indications of CV 23, 35 to types of disorders such as asthma, cough, tongue swelling with difficulty in speaking, protracted tongue, acute contraction of tongue root, vomiting, spasm syndrome, stroke, aphtha, problems of mouth and teeth, throat problems, etc. of the internal medicine, surgery, pediatrics, and five-sense organs; 64 items are referred to the application of single CV 23, 91 to CV 23-included recipes containing 111 adjunct acupoints, and 78 to stimulation of CV 23 with acupuncture needle, moxibustion, pricking blood, and fire needle. Moreover, of the 111 adjunct acupoints, the most commonly used are Shaoshang (LU 11), Tiantu (CV 22), Hegu (LI 4), Yuye (EX-HN 13), Zhongchong (PC 9), etc. Lianquan (CV 23) is mainly used for glossopharyngeal problems chiefly by syndrome-meridian differentiation. The supplement of complementary acupoints or five-shu points in combination with CV 23 has a synergistic effect. Moxibustion (3 moxa- cones in general) is often employed, and the needling depth is usually about 7.5 mm. The common contraindication of CV 23 is severe tongue swelling.

    Frequency-dependent capacitance-voltage fluence (C-V) characteristics of neutron irradiated high resistivity silicon p + -n detectors have been observed up to a fluence of 8.0 x 10 12 n/cm 2 . It has been found that frequency dependence of the deviation of the C-V characteristic (from its normal V -1/2 dependence), is strongly dependent on the ratio of the defect density and the effective doping density N t /N' d . As the defect density approaches the effective dopant density, or N t /N' d → 1, the junction capacitance eventually assumes the value of the detector geometry capacitance at high frequencies (f ≤ 10 5 Hz), independent of voltage. A two-trap-level model using the concept of quasi-fermi levels has been developed, which predicts both the effects of C-V frequency dependence and dopant compensation observed in this study

    Water pollution from the release of industrial wastewater is a serious problem for almost every industry. Enzymes from portulaca, Portulaca oleracea cv., have been investigated for their ability to degrade bisphenol A (BPA), one of the well-known estrogenic pollutants. Enzymatic crude extracts from P. oleracea cv. roots were immobilized on aminopropyl-modified glass beads. They maintained BPA metabolic activity over a broad range of pH values and temperatures. The immobilized enzyme was reusable with more than 50 % of its initial activity retained after 12 batch reactions and no loss of activity after storage for 1 month at -30 °C. Thus, the immobilization of extracts from P. oleracea cv. roots is a useful method for removing BPA from industrial wastewater.

    A short period eclipsing binary star CV Boo is tested for the possible existence of additional bodies in the system with a help of the light equation method. We use data on the moments of minima from the literature as well as from our observations during 2014 May-July. A variation of the CV Boo's orbital period is found with a period of {≈}75 d. This variation can be explained by the influence of a third star with a mass of {≈}0.4 M_{⊙} in an eccentric orbit with e≈0.9. A possibility that the orbital period changes on long time scales is discussed. The suggested tertiary companion is near the chaotic zone around the central binary, so CV Boo represents an interesting example to test its dynamical evolution. A list of 14 minima moments of the binary obtained from our observations is presented.

    This paper presents an approach for kidney segmentation on abdominal CT images as the first step of a virtual reality surgery system. Segmentation for medical images is often challenging because of the objects' complicated anatomical structures, various gray levels, and unclear edges. A coarse to fine approach has been applied in the kidney segmentation using Chan-Vese model (C-V model) and anatomy prior knowledge. In pre-processing stage, the candidate kidney regions are located. Then C-V model formulated by level set method is applied in these smaller ROI, which can reduce the calculation complexity to a certain extent. At last, after some mathematical morphology procedures, the specified kidney structures have been extracted interactively with prior knowledge. The satisfying results on abdominal CT series show that the proposed approach keeps all the advantages of C-V model and overcome its disadvantages.

    Calcium-aluminum-rich inclusions (CAIs) are the oldest dated materials in the Solar System and numerous previous studies have revealed nucleosynthetic anomalies relative to terrestrial rock standards in many isotopic systems. However, most of the isotopic data from CAIs has been limited to the Allende meteorite and a handful of other CV3 chondrites. To better constrain the isotopic composition of the CAI-forming region, we report the first Sr, Mo, Ba, Nd, and Sm isotopic compositions of two CAIs hosted in the CK3 desert meteorites NWA 4964 and NWA 6254 along with two CAIs from the CV3 desert meteorites NWA 6619 and NWA 6991. After consideration of neutron capture processes and the effects of hot-desert weathering, the Sr, Mo, Ba, Nd, and Sm stable isotopic compositions of the samples show clearly resolvable nucleosynthetic anomalies that are in agreement with previous results from Allende and other CV meteorites. The extent of neutron capture, as manifested by shifts in the observed 149Sm-150Sm isotopic composition of the CAIs is used to estimate the neutron fluence experienced by some of these samples and ranges from 8.40 × 1013 to 2.11 × 1015 n/cm2. Overall, regardless of CAI type or host meteorite, CAIs from CV and CK chondrites have similar nucleosynthetic anomalies within analytical uncertainty. We suggest the region that CV and CK CAIs formed was largely uniform with respect to Sr, Mo, Ba, Nd, and Sm isotopes when CAIs condensed and that CAIs hosted in CV and CK meteorites are derived from the same isotopic reservoir.

    A new meteorite find, named Khatyrka, was recovered from eastern Siberia as a result of a search for naturally occurring quasicrystals. The meteorite occurs as clastic grains within postglacial clay-rich layers along the banks of a small stream in the Koryak Mountains, Chukotka Autonomous Okrug of far eastern Russia. Some of the grains are clearly chondritic and contain Type IA porphyritic olivine chondrules enclosed in matrices that have the characteristic platy olivine texture, matrix olivine composition, and mineralogy (olivine, pentlandite, nickel-rich iron-nickel metal, nepheline, and calcic pyroxene [diopside-hedenbergite solid solution]) of oxidized-subgroup CV3 chondrites. A few grains are fine-grained spinel-rich calcium-aluminum-rich inclusions with mineral oxygen isotopic compositions again typical of such objects in CV3 chondrites. The chondritic and CAI grains contain small fragments of metallic copper-aluminum-iron alloys that include the quasicrystalline phase icosahedrite. One grain is an achondritic intergrowth of Cu-Al metal alloys and forsteritic olivine ± diopsidic pyroxene, both of which have meteoritic (CV3-like) oxygen isotopic compositions. Finally, some grains consist almost entirely of metallic alloys of aluminum + copper ± iron. The Cu-Al-Fe metal alloys and the alloy-bearing achondrite clast are interpreted to be an accretionary component of what otherwise is a fairly normal CV3 (oxidized) chondrite. This association of CV3 chondritic grains with metallic copper-aluminum alloys makes Khatyrka a unique meteorite, perhaps best described as a complex CV3 (ox) breccia.

    MIL 090001 is a large (greater than 6 kg) CV chondrite from the reduced subgroup (CV(sub red)) that was recovered during the 2009-2010 ANSMET field season [1]. The CV(sub red) subgroup meteorites retain primitive characteristics and have escaped the Na and Fe meta-somatism that affected the oxidized (CV(sub ox)) subgroups. MIL 090001 is, however, reported to be altered [1], and thus a major objective of this study is to characterize its mineralogy and petrography and the extent of the alteration.

  14. Possibility of Recombination Gain Increase in CV Ions at 4.0 nm Via Coherence

    Science.gov (United States)

    Luo, Y.; Morozov, A.; Gordon, D.; Sprangle, P.; Svidzinsky, A.; Xia, H.; Scully, M.; Suckewer, S.

    This paper is about the recent experimental results on amplification of the CV line in the "water window" at 4.03 nm from resonance transition to the ground level of He-like ions in recombination scheme. The indication of the amplification of the CV line has been observed when an elongated narrow plasma channel was created, where high intensity 100 fs beams, optimal for creating CV ions in high density plasma, was propagated up to 0.5-0.6 mm. Without channeling the effective plasma length was much shorter and there was no indication of amplification.The large interest in gain generation in He-like ions in the transition to ground state is due to the possibility of applying a recently developed theory of Lasing Without Inversion (LWI) in XUV and X-ray regions to largely increase the gain for such transitions. The presented results of the indication of CV line amplifications are being discussed from the point of view of using LWI as a superradiance gain increase, hence to construct a very compact soft X-ray laser in the "water window".The last part of the paper is related to the application of the ultra-intensive fs plasma laser, which is currently in the process of development by using stimulated Raman backscattering (SRBS) to create a plasma amplifier and compressor, as the pump for compact laser operating in the "water window" and also at shorter wavelengths.

    As plant fibres are increasingly used in technical textiles and their composites, underlying principles of wound healing in living plant fibres are relevant to product quality, and provide inspiration for biomimetic healing in synthetic materials. In this work, two Linum usitatissimum cultivars differing in their stem mechanical properties, cv. Eden (stems resistant to lodging) and cv. Drakkar (with more flexible stems), were grown without wound or with stems previously wounded with a cut parallel or transversal to the stem. To investigate wound healing efficiency, growth traits, stem biomechanics with Dynamic Mechanical Analysis and anatomy were analysed after 25-day recovery. Longitudinal incisions formed open wounds while transversal incisions generated stem growth restoring the whole cross-section but not the original stem organisation. In the case of transversal wound healing, all the bast fibre bundles in the perturbed area became lignified and pulled apart by parenchyma cells growth. Both Linum cultivars showed a healing efficiency from 79% to 95% with higher scores for transversal healing.

    Effect of the addition of avocado (Persea americana cv. Hass) or olive (Olea europaea cv. Arbequina) hydroalcoholic leaf extracts (AHE and OHE, respectively) on thermal stability of canola oil (CO) and high oleic sunflower oil (HOSO) during French potatoes frying at 180°C was studied. The extracts were characterized by the total phenolic content, phenol chromatographic profiles and antioxidant activity. B-type trimer procyanidins were the major phenolic compounds identified in AHE. OHE showed higher phenol content, antioxidant activity regarding AHE. CO+OHE and HOSO+OHE decreased the formation of polar compounds and showed an anti-polymeric effect with respect to oils without extracts, whereas AHE extract showed a prooxidant effect on HOSO. Therefore, OHE showed an antioxidant effect on HOSO and CO under the studied conditions. In addition, all systems (CO+AHE, HOSO+AHE, CO+OHE and HOSO+OHE) increased the retention of tocopherols. These results demonstrate the potential utility of OHE as natural antioxidant for oils. Copyright © 2016 Elsevier Ltd. All rights reserved.

    1990-10-01

    A new automated quasi-static C-V measurement technique for MOS capacitors has been developed. This techniques uses an integrating electrometer to measure the charge accumulated on a MOS capacitor in response of a small voltage step. Making use of the internal data storage system of a commercial electrometer and a personal computer, the charge Q on the MOS capacitor is measured as a function of time t and stored. The capacitance is then obtained by analyzing this Q-t data set. A Si MOS sample is measured and analyzed in terms of interface charges as an example. Advantages over a commercial quasi-static meter which uses similar measurement technique are presented. It is also shown that this technique is potentially capable of measuring both high and low frequency C-V curves simultaneously. 9 refs. 5 figs

    Visceral Leishmaniasis is a parasitic disease that affects liver, spleen and bone marrow. According to World Health Organization report, definitive diagnosis is possible just by direct observation of the Leishman body in the microscopic image taken from bone marrow samples. We utilize morphological and CV level set method to segment Leishman bodies in digital color microscopic images captured from bone marrow samples. Linear contrast stretching method is used for image enhancement and morphological method is applied to determine the parasite regions and wipe up unwanted objects. Modified global and local CV level set methods are proposed for segmentation and a shape based stopping factor is used to hasten the algorithm. Manual segmentation is considered as ground truth to evaluate the proposed method. This method is tested on 28 samples and achieved 10.90% mean of segmentation error for global model and 9.76% for local model.

    2017-02-01

    We present the results of a search for extremely metal-poor (EMP), carbon-enhanced metal-poor (CEMP), and cataclysmic variable (CV) stars using a new exploration tool based on linked scatter plots (LSPs). Our approach is especially designed to work with very large spectrum data sets such as the SDSS, LAMOST, RAVE, and Gaia data sets, and it can be applied to stellar, galaxy, and quasar spectra. As a demonstration, we conduct our search using the SDSS DR10 data set. We first created a 3326-dimensional phase space containing nearly 2 billion measures of the strengths of over 1600 spectral features in 569,738 SDSS stars. These measures capture essentially all the stellar atomic and molecular species visible at the resolution of SDSS spectra. We show how LSPs can be used to quickly isolate and examine interesting portions of this phase space. To illustrate, we use LSPs coupled with cuts in selected portions of phase space to extract EMP stars, CEMP stars, and CV stars. We present identifications for 59 previously unrecognized candidate EMP stars and 11 previously unrecognized candidate CEMP stars.

    Inhibitors of the Wingless-related Integration site (WNT)/β-catenin pathway have recently been under consideration as potential chemopreventive agents against Familial Adenomatous Polyposis (FAP). This autosomal-dominant syndrome is caused by germline mutations in the gene coding for the protein APC and leads to hyperactivation of the WNT/β-catenin signaling pathway, uncontrolled intestinal cell proliferation and formation of adenocarcinomas. The aim of the present work was to: (i) test, on in vitro cultures of cells carrying FAP mutations and on ex vivo biopsies of FAP patients, the WNT inhibitory activity of extracts from two common southern Italian apples, Malus pumila Miller cv. 'Annurca' and Malus domestica cv 'Limoncella'; (ii) identify the mechanisms underpinning their activities and; (iii) evaluate their potency upon gastrointestinal digestion. We here show that both Annurca and Limoncella apple extracts act as WNT inhibitors, mostly thanks to their polyphenolic contents. They inhibit the pathway in colon cells carrying FAP mutations with active dilutions falling in ranges close to consumer-relevant concentrations. Food-grade manufacturing of apple extracts increases their WNT inhibitory activity as result of the conversion of quercetin glycosides into the aglycone quercetin, a potent WNT inhibitor absent in the fresh fruit extract. However, in vitro simulated gastrointestinal digestion severely affected WNT inhibitory activity of apple extracts, as result of a loss of polyphenols. In conclusion, our results show that apple extracts inhibit the WNT pathway in colon cells carrying FAP mutations and represent a potential nutraceutical alternative for the treatment of this pathology. Enteric coating is advisable to preserve the activity of the extracts in the colon-rectal section of the digestive tract.

  15. Defective secretion of mucilage is the cellular basis for agravitropism in primary roots of Zea mays cv. Ageotropic

    Science.gov (United States)

    Miller, I.; Moore, R.

    1990-01-01

    Root caps of primary, secondary, and seminal roots of Z. mays cv. Kys secrete large amounts of mucilage and are in close contact with the root all along the root apex. These roots are strongly graviresponsive. Secondary and seminal roots of Z. mays cv. Ageotropic are also strongly graviresponsive. Similarly, their caps secrete mucilage and closely appress the root all along the root apex. However, primary roots of Z. mays cv. Ageotropic are non-responsive to gravity. Their caps secrete negligible amounts of mucilage and contact the root only at the extreme apex of the root along the calyptrogen. These roots become graviresponsive when their tips are coated with mucilage or mucilage-like materials. Peripheral cells of root caps of roots of Z. mays cv. Kys contain many dictyosomes associated with vesicles that migrate to and fuse with the plasmalemma. Root-cap cells of secondary and seminal (i.e. graviresponsive) roots of Z. mays cv. Ageotropic are similar to those of primary roots of Z. mays cv. Kys. However, root-cap cells of primary (i.e. non-graviresponsive) roots of Z. mays cv. Ageotropic have distended dictyosomal cisternae filled with an electron-dense, granular material. Large vesicles full of this material populate the cells and apparently do not fuse with the plasmalemma. Taken together, these results suggest that non-graviresponsiveness of primary roots of Z. mays cv. Ageotropic results from the lack of apoplastic continuity between the root and the periphery of the root cap. This is a result of negligible secretion of mucilage by cells along the edge of the root cap which, in turn, appears to be due to the malfunctioning of dictyosomes in these cells.

    Plaque development for either untreated or UV treated irradiated Herpes simplex virus Type 1 was faster when assayed on UV irradiated CV1 cells. This Large Plaque Effect only occurred if a minimum delay of 12h between cell irradiation and viral inoculation was allowed. Shorter delays gave plaques that were smaller than controls (unirradiated virus-unirradiated cells). The effect was maximal for a 48-h delay and remained unchanged for delays as long as 84h. The effect was greatest for cell exposures of 10Jm -2 . (author)

Merlot R18, MCL 519 and grapevine rootstocks Kober 5BB (Vitis berlandieri x V. riparia, SO4 (V. berlandieri x V. riparia and 41B (Chasselas x V.berlandieri were investigated. The trial was conducted in commercial grapevine nursery located in Velika Drenova, Serbia. As an index of compatibility, grade of high quality grapevine grafted rootlings, dry matter in mature shoots and root system development were used. Grafting was done by `tongue grafting` indoor technique. Stratifi cation was done in sand, on temperature of the stratifi cation material of 26-28oC, and humidity of around 90%. Grafted cuttings were waxed twice: before stratifi cation, and before planting in the nursery. Grafted rootlings were classed in two classes according to regulations of quality, (Yugoslav Offi cial Register, 26/79. Grafted rootlings that did not satisfi ed standard criteria were discarded. Both clones of cv. Chardonnay gave the highest percentage of I class grafted rootlings on grapevine rootstock 41B: clone BCL 75 – 60% and clone VCR4 – 61%. In the same combination, those grapevine grafted rootlings had the highest weight of the root system. Lower percentage of obtained I class grafted rootlings was established on rootstock Kober 5BB, while statistically signifi cantly lower yields were obtained on grapevine rootstock SO4: clone BCL75 – 43% and clone VCR4 – 48%.

    We explore the relevance of Heterogeneous System Architecture (HSA) in Computer Vision, both as a long term vision, and as a near term emerging reality via the recently ratified OpenCL 2.0 Khronos standard. After a brief review of OpenCL 1.2 and 2.0, including HSA features such as Shared Virtual Memory (SVM) and platform atomics, we identify what genres of Computer Vision workloads stand to benefit by leveraging those features, and we suggest a new mental framework that replaces GPU compute with hybrid HSA APU compute. As a case in point, we discuss, in some detail, popular object recognition algorithms (part-based models), emphasizing the interplay and concurrent collaboration between the GPU and CPU. We conclude by describing how OpenCL has been incorporated in OpenCV, a popular open source computer vision library, emphasizing recent work on the Transparent API, to appear in OpenCV 3.0, which unifies the native CPU and OpenCL execution paths under a single API, allowing the same code to execute either on CPU or on a OpenCL enabled device, without even recompiling.

    In order to identification of the possibility of manufacturing soybean paste (doenjang) with soybean mutant lines induced from gamma-ray mutagenesis, this study was performed to investigate the quality characteristics of doenjang using two soybean mutant lines, Baekwon-1 (BW-1) and Baekwon-2 (BW-2) and their original cultivar (cv. Baekwon, BW) for 8 weeks. The BW and two mutant lines (BW-1 and BW-2) were showed higher content of amino type nitrogen than control (cv. Taegwang). The pH decreased and the titratable acidity increased all the samples during aging period. The lightness, redness and yellowness of doenjang were the lowest in BW. Total free sugar content of doenjang was the highest in control (10.43%) after 4 weeks and composed mainly fructose and glucose. The order of the free amino acid content was Glutamic acid>Leucine>Lysine>Phenylalanine>Aspartic acid in control, Glutamic acid>Leucine >Arginine>Lysine>Phenylalanine in BW, Glutamic acid>Lysine>Phenylalanine>Aspartic acid>Valine in BW-1 and Glutamic acid>Arginine>Lysine>Phenylalanine>Aspartic acid in BW-2, respectively. Our results showed that it is possible to increase the quality of doenjang using soybean mutant lines in manufacturing soybean paste

    Full Text Available The use of pulse solutions containing antimicrobials has been reported, but more research is necessary. To increase vase life and to study their effect on opening inflorescences, silver nanoparticles were used in vase solutions for cv. Puma Chrysanthemum stems. The nanoparticles were synthesized biologically using Chenopodium ambrosioides L. applied at concentrations of 0.01, 0.05, 0.1, 0.5, 1, and 5 mM and compared with a control. Treatments were replicated five times. The stems were cut to 50 cm and observed until the end of their vase life. Low concentrations of silver nanoparticles promoted inflorescence opening and leaf yellowing, while the control leaves remained green, but there was a lower degree of inflorescence opening. High concentrations of silver nanoparticles (0.5, 1, and 5 mM caused senescence due to low water uptake through the stems. Statistical differences in inflorescence opening and diameter, bacterial growth (CFU mL−1 in vase solutions, fresh weight, water uptake, and vase life were found among treatments. Longer vase life and less weight loss were observed in the stems exposed to low concentrations of silver nanoparticles. Low concentrations of silver nanoparticles promoted inflorescence opening and increased vase life of Chrysanthemum cv. Puma.

    Full Text Available Mango (Mangifera indica cv. Ataulfo peel contains bound phenolics that may be released by alkaline or acid hydrolysis and may be converted into less complex molecules. Free phenolics from mango cv. Ataulfo peel were obtained using a methanolic extraction, and their cellular antioxidant activity (CAA and permeability were compared to those obtained for bound phenolics released by alkaline or acid hydrolysis. Gallic acid was found as a simple phenolic acid after alkaline hydrolysis along with mangiferin isomers and quercetin as aglycone and glycosides. Only gallic acid, ethyl gallate, mangiferin, and quercetin were identified in the acid fraction. The acid and alkaline fractions showed the highest CAA (60.5% and 51.5% when tested at 125 µg/mL. The value of the apparent permeability coefficient (Papp across the Caco-2/HT-29 monolayer of gallic acid from the alkaline fraction was higher (2.61 × 10−6 cm/s than in the other fractions and similar to that obtained when tested pure (2.48 × 10−6 cm/s. In conclusion, mango peels contain bound phenolic compounds that, after their release, have permeability similar to pure compounds and exert an important CAA. This finding can be applied in the development of nutraceuticals using this important by-product from the mango processing industry.

    An efficient protocol was standardized for screening of panama wilt resistant Musa paradisiaca cv. Puttabale clones, an endemic cultivar of Karnataka, India. The synergistic effect of 6-benzyleaminopurine (2 to 6 mg/L) and thidiazuron (0.1 to 0.5 mg/L) on MS medium provoked multiple shoot induction from the excised meristem. An average of 30.10 +/- 5.95 shoots was produced per propagule at 4 mg/L 6-benzyleaminopurine and 0.3 mg/L thidiazuron concentrations. Elongation of shoots observed on 5 mg/L BAP augmented medium with a mean length of 8.38 +/- 0.30 shoots per propagule. For screening of disease resistant clones, multiple shoot buds were mutated with 0.4% ethyl-methane-sulfonate and cultured on MS medium supplemented with Fusarium oxysporum f. sp. cubense (FOC) culture filtrate (5-15%). Two month old co-cultivated secondary hardened plants were used for screening of disease resistance against FOC by the determination of biochemical markers such as total phenol, phenylalanine ammonia lyase, oxidative enzymes like peroxidase, polyphenol oxidase, catalase and PR-proteins like chitinase, beta-1-3 glucanase activities. The mutated clones of M. paradisiaca cv. Puttabale cultured on FOC culture filtrate showed significant increase in the levels of biochemical markers as an indicative of acquiring disease resistant characteristics to FOC wilt.

    Full Text Available For the island coastline segmentation, a fast segmentation algorithm for C-V model method based on exponential image sequence generation is proposed in this paper. The exponential multi-scale C-V model with level set inheritance and boundary inheritance is developed. The main research contributions are as follows: 1 the problems of the "holes" and "gaps" are solved when extraction coastline through the small scale shrinkage, low-pass filtering and area sorting of region. 2 the initial value of SDF (Signal Distance Function and the level set are given by Otsu segmentation based on the difference of reflection SAR on land and sea, which are finely close to the coastline. 3 the computational complexity of continuous transition are successfully reduced between the different scales by the SDF and of level set inheritance. Experiment results show that the method accelerates the acquisition of initial level set formation, shortens the time of the extraction of coastline, at the same time, removes the non-coastline body part and improves the identification precision of the main body coastline, which automates the process of coastline segmentation.

    The type of video that used in this proposed hiding a secret information technique is .AVI; the proposed technique of a data hiding to embed a secret information into video frames by using Discrete Cosine Transform (DCT), Discrete Wavelet Transform (DWT) and Curvelet Transform (CvT). An individual pixel consists of three color components (RGB), the secret information is embedded in Red (R) color channel. On the receiver side, the secret information is extracted from received video. After extracting secret information, robustness of proposed hiding a secret information technique is measured and obtained by computing the degradation of the extracted secret information by comparing it with the original secret information via calculating the Normalized cross Correlation (NC). The experiments shows the error ratio of the proposed technique is (8%) while accuracy ratio is (92%) when the Curvelet Transform (CvT) is used, but compared with Discrete Wavelet Transform (DWT) and Discrete Cosine Transform (DCT), the error rates are 11% and 14% respectively, while the accuracy ratios are (89%) and (86%) respectively. So, the experiments shows the Poisson noise gives better results than other types of noises, while the speckle noise gives worst results compared with other types of noises. The proposed technique has been established by using MATLAB R2016a programming language.

    In their groundbreaking work featuring verbal dichotic listening tasks, Mondor and Bryden showed that tone cues do not enhance children's attentional orienting, in contrast to adults. The magnitude of the children's right-ear advantage was not attenuated when their attention was directed to the left ear. Verbal cues did, however, appear to favour the orientation of attention at around 10 years, although stimulus-onset asynchronies (SOAs), which ranged between 450 and 750 ms, were not rigorously controlled. The aim of our study was therefore to investigate the role of both types of cues in a typical CV-syllable dichotic listening task administered to 8- to 10-year-olds, applying a protocol as similar as possible to that used by Mondor and Bryden, but controlling for SOA as well as for cued ear. Results confirmed that verbal cues are more effective than tone cues in orienting children's attention. However, in contrast to adults, no effect of SOA was observed. We discuss the relative difficulty young children have processing CV syllables, as well as the role of top-down processes in attentional orienting abilities.

  1. Testing Anchoring effect in CV Data from Dichotomous Choice with a Follow-up Questioning

    A questionnaire of dual bisected selection of CVM, which is an induced approach of intended payment, was suggested to overcome statistical inefficiency of a questionnaire of single bisected selection. In spite of several advantages of it, it is doubted that there would be an occurrence of anchoring effect, which is a psychological source of convenient starting point. Therefore, the general intended payment model, which can review the anchoring effect from CV questionnaire of dual bisected selection, was suggested and a mechanism that can review the anchoring effect from the model. This model is combining the dual variation model by Cameron and Quiggin (1994) with the results of bisected selective responses of a firstly presented particular amount as an explanatory variable of the second interior intended payment amount. If the sign of coefficient of the results of bisected selective responses of a firstly presented particular amount was negative and statistically significant, then it can be said that there is an anchoring effect. However, when there is uncertainty of occurrence of anchoring effect from the coefficient review, there is no need to worry about the anchoring effect if the average of estimated values of intended payment amount from two responses were different. As a result of applying this model and mechanism to CV materials on the improvement of water quality of the Han River, there is no need to worry about the anchoring effect.

    Full Text Available The Instituto Nacional de Investigaciones Agrícolas (INIA, Venezuela, is producing potato seed by biotechnology in its National Seed Plan. The seeds needed are greater than the installed capacity. The acquisition of temporary immersion system (ITS enables developing research in the production of seed potatoes to ensure quality, efficiency and reduced production costs. The purchase of seeds will decrease and contribute to food security and sovereignty of the country. This work was aimed to obtain potato microtubers cv. ‘Andinita’ in SIT. In vitro plants propagated by organogenesis and SIT in 10 liters capacity were used. Explants (100 were inoculated per pot. After five weeks in multiplication a change of culture medium was carried out to induce tuberization. Three immersion frequencies were tested. Plant height was measured and the number of microtubers and fresh dough was quantified. Potato microtubers cv. ‘Andinita’ in SIT were obtained. The best results were achieved with immersions every four hours, averaging five to seven microtubers per plant (approximately 600 microtubers per culture vessel, with sizes between 4 and 16 mm, with an average of 3 g fresh weight, which ensured budding efficiency and allow direct field planting. This result constitutes the first report of the use of SIT for propagation of potatoes in Venezuela. This is a new possibility to use SIT in other varieties.

    Full Text Available The genus Heliconia is commercially detached by the exotic appearance of the inflorescences but is susceptible to lack of moisture in the soil, being necessary the irrigation management. In this sense, the objective was to evaluate the effect of different irrigation levels on the plant growth and productive characters of Heliconia psittacorum cv. Golden Torch cultivated in vase. The experiment was conducted from March to October 2014, in a randomized blocks design. Five treatments corresponding to the different irrigation levels were used [50, 75, 100, 125 and 150% of the evaporation measured in Class A (ECA] with four replicates and two plants per replicate. The following evaluations were carried out: number of days for the emergence of the first tiller, number of days for the emergence of the first inflorescence, number of days for the inflorescence harvest, crop cycle, diameter of the flower stem, length of the flower stem, inflorescence length, plant high, number of tillers and productivity of flower stems. Chlorophyll and leaf area measurements were performed. The irrigation levels tested significantly influenced the number of days for the first inflorescence harvest, length of the flower stem and inflorescence length. The irrigation level of 150% ECA provided better results for the length of the flower stem, inflorescence length and for leaf area but without differences from 75%, 100% and 125% ECA. Thus, for the cultivation of the heliconia cv. Golden Torch in pot can be recommended the level corresponding from 75% to 150% ECA.

    Full Text Available The use of methyl jasmonate has demonstrated its efficiency to extend the vase life of cut flowers. The objective of this study was to evaluate the effect of methyl jasmonate associated with storage at low temperatures on the postharvest quality of Rosa cv. Avalanche stems. The treatments consisted of 125, 250, 500 and 1000 μM of methyl jasmonate, besides the control with distilled water. The flower buds were sprayed with 4 mL of the solution, according to the treatments, and then kept in a cold chamber (1 °C for periods of 2 and 6 days. Subsequently, the stems were taken to the postharvest laboratory at a temperature of 16 °C. Better quality, higher fresh weight and water absorption were observed in flower stems stored for 2 days. The application of methyl jasmonate caused less turgescence and greater darkening of roses. It was possible to conclude that two days is the best storage time at 1 °C and the use of methyl jasmonate does not maintain the quality of roses cv. Avalanche after harvest.

    Mango ( Mangifera indica cv. Ataulfo) peel contains bound phenolics that may be released by alkaline or acid hydrolysis and may be converted into less complex molecules. Free phenolics from mango cv. Ataulfo peel were obtained using a methanolic extraction, and their cellular antioxidant activity (CAA) and permeability were compared to those obtained for bound phenolics released by alkaline or acid hydrolysis. Gallic acid was found as a simple phenolic acid after alkaline hydrolysis along with mangiferin isomers and quercetin as aglycone and glycosides. Only gallic acid, ethyl gallate, mangiferin, and quercetin were identified in the acid fraction. The acid and alkaline fractions showed the highest CAA (60.5% and 51.5%) when tested at 125 µg/mL. The value of the apparent permeability coefficient (Papp) across the Caco-2/HT-29 monolayer of gallic acid from the alkaline fraction was higher (2.61 × 10 -6 cm/s) than in the other fractions and similar to that obtained when tested pure (2.48 × 10 -6 cm/s). In conclusion, mango peels contain bound phenolic compounds that, after their release, have permeability similar to pure compounds and exert an important CAA. This finding can be applied in the development of nutraceuticals using this important by-product from the mango processing industry.

    Full Text Available One of the most important limiting factors in spread of apricot in Iran is late spring frost, which damages flower bud and decrease total yield of crop. It has been found that ascorbic acid (AA plays a beneficial role during plant response to chilling and freezing stresses. To evaluate the effects of AA on alleviating of cold stress, the flower buds of Prunus armeniaca L. cv. Shahroudi were sprayed at pink cluster stage with AS at 4 levels (0, 100, 200 and 300 mg. L-1 and were then exposed to artificial cold stress (4 h at –4 °C or without cold stress (+ 25°C. Experimental attributes including electrolyte leakage (EL of flower buds and percentage of damage of pistil, anthers and petals to temperature treatments were determined. The results showed that at - 4°C the lowest and highest percentage of damage and EL of flower buds were observed in application of 200 and 0 mg. L-1 AA, respectively. The highest and lowest percentage of damage of flower organs and EL were obtained in application of 300 and 200 mg. L-1 AA, respectively at + 25 °C. Based on the results of this experiment, AA alleviates the negative effect of cold stress on EL and flower organ damages in apricot cv. Shahroudi, depending on the concentrations of AA used.

    Electrical properties of Schottky- and metal-insulator-semiconductor (MIS)-gate SiGe/Si high electron mobility transistors (HEMTs) were investigated with capacitance-voltage (C-V) measurements. The MIS-gate HEMT structure was fabricated using a SiN gate insulator formed by catalytic chemical vapor deposition (Cat-CVD). The Cat-CVD SiN thin film (5 nm) was found to be an effective gate insulator with good gate controllability and dielectric properties. We previously investigated device characteristics of sub-100-nm-gate-length Schottky- and MIS-gate HEMTs, and reported that the MIS-gate device had larger maximum drain current density and transconductance (g m ) than the Schottky-gate device. The radio frequency (RF) measurement of the MIS-gate device, however, showed a relatively lower current gain cutoff frequency f T compared with that of the Schottky-gate device. In this study, C-V characterization of the MIS-gate HEMT structure demonstrated that two electron transport channels existed, one at the SiGe/Si buried channel and the other at the SiN/Si surface channel

    Enhanced reactivation of UV- and γ-irradiated herpes virus was investigated by the plaque assay on CV-1 monkey kidney monolayer cells irradiated with UV light or X-rays. Both UV- and X-irradiated CV-1 cells showed enhancement of survival of UV-irradiated virus, while little or no enhancement was detected for γ-irradiated virus assayed on UV- or X-irradiated cells. The enhanced reactivation of UV-irradiated virus was greater when virus infection was delayed 24 or 48 h, than for infection immediately following the irradiation of cells. Thus the UV- or X-irradiated CV-1 cells are able to enhance the repair of UV damaged herpes virus DNA, but not of γ-ray damaged ones. (author)

    The present study aimed to investigate the effect of electroacupuncture stimulation at CV4 (also termed Guanyuan) on femoral osteocalcin also termed bone gla protein (BGP), alkaline phosphatase (ALP), bone mineral density (BMD) and biomechanics, as well as the Wnt‑β‑catenin signaling pathway in rats with postmenopausal osteoporosis. Female Sprague‑Dawley rats (4.5‑months old) were randomly divided into sham, Ovx, CV4 and mock groups (n=10/group). With the exception of those in the sham group, the rats were ovariectomized to induce postmenopausal osteoporosis. The rats in the CV4 and mock groups were given electroacupuncture at CV4 and non‑acupoint, respectively. The rats in the Ovx model and sham groups underwent identical fixing procedures, but did not undergo electroacupuncture. Following treatment, hematoxylin and eosin staining was used to observe morphological changes in the left femoral trabecular bone, and a three‑point‑bending test was used to analyze femur biomechanics and determine the BMD. In addition, an enzyme‑linked immunosorbent assay was used to measure the serum levels of ALP/BGP and reverse transcription‑quantitative polymerase chain reaction was used detect the expression levels of Wnt3a, β‑catenin and Runx2. In the present study, it was demonstrated that electroacupuncture at CV4 significantly improved the osteoporotic morphological changes that occurred in the ovariectomized rats, increased serum ALP and BGP levels, enhanced the maximum and fracture loads, increased BMD (Pelectroacupuncture stimulation at CV4 affected bone formation and promoted bone metabolism in rats with postmenopausal osteoporosis, possibly by activating the Wnt‑β‑catenin signaling pathway.

    This work details the analysis of wafer level global process variability in 28 nm FD-SOI using split C-V measurements. The proposed approach initially evaluates the native on wafer process variability using efficient extraction methods on split C-V measurements. The on-wafer threshold voltage (VT) variability is first studied and modeled using a simple analytical model. Then, a statistical model based on the Leti-UTSOI compact model is proposed to describe the total C-V variability in different bias conditions. This statistical model is finally used to study the contribution of each process parameter to the total C-V variability.

  1. Inducing gravitropic curvature of primary roots of Zea mays cv Ageotropic

    Science.gov (United States)

    Moore, R.; Evans, M. L.; Fondren, W. M.

    1990-01-01

    Primary roots of the mutant 'Ageotropic' cultivar of Zea mays are nonresponsive to gravity. Their root caps secrete little or no mucilage and touch the root only at the extreme apex. A gap separates the cap and root at the periphery of the cap. Applying mucilage from normal roots or substances with a consistency similar to that of mucilage to tips of mutant roots causes these roots to become strongly graviresponsive. Gravicurvature stops when these substances are removed. Caps of some mutants secrete small amounts of mucilage and are graviresponsive. These results indicate that (a) the lack of graviresponsiveness in the mutant results from disrupting the transport pathway between the cap and root, (b) movement of the growth-modifying signal from the cap to the root occurs via an apoplastic pathway, and (c) mucilage is necessary for normal communication between the root cap and root in Zea mays cv Ageotropic.

    The effects of irrigation water or soil salinity on physiological aspects of pea (Pisum sativum cv.Meteor) were contrived. Ten weeks old pea plants were treated with NaCl at 0, 40, 90 and 140 mM in nutrient solution Plants were grown in controlled environment and harvested at each 3 days interval for decisiveness 0 physiological parameters. Photosynthetic rate, relative water content, stomatal conductance and chlorophyll contents reduced by increasing the NaCI concentration while CO/sub 2/ concentration and free proline content intensified. By experiment it was adumbrated that high salinity level along with prolonged accentuate duration is more drastic to pea plants physiology. Results also exhibited that pea plants could indulge 40 and 90 mM NaCl but are sensitive to 140 mM. (author)

    Mutation induction was used with the objective of obtaining mutants for flower colour of chrysanthemum, cv. Repin (pink colour). Rooted cuttings were irradiated with 20 Gy of gamma rays and before the selection the cutting back method was used to advance the generations. The frequency of colour mutants observed was 5.8%. Among the mutants obtainedthe white and dark-pink-coloured ones were evaluated in yield trial and post-harvest. The results indicated that these mutants mantained the same agronomical characteristics showed by the control, with the exception of plant height in the white mutant that was shorter. Due to commercial interest of the producers, these mutants were multiplied and released as new cultivars. The white flower colour mutant was named Cristiane and the dark-pink, Ingrid. This was the first example of cultivars from an ornamental plant released by mutation breeding in Brazil. (author)

    Full Text Available Aimed at the established telenanomanipulation system, the method of extracting location information and the strategies of probe operation were studied in this paper. First, the machine learning algorithm of OpenCV was used to extract location information from SEM images. Thus nanowires and probe in SEM images can be automatically tracked and the region of interest (ROI can be marked quickly. Then the location of nanowire and probe can be extracted from the ROI. To study the probe operation strategy, the Van der Waals force between probe and a nanowire was computed; thus relevant operating parameters can be obtained. With these operating parameters, the nanowire in 3D virtual environment can be preoperated and an optimal path of the probe can be obtained. The actual probe runs automatically under the telenanomanipulation system's control. Finally, experiments were carried out to verify the above methods, and results show the designed methods have achieved the expected effect.

    2014-03-01

    Thomas Jefferson National Accelerator Facility (TJNAF) uses superconducting radiofrequency (SRF) cavities to accelerate an electron beam. If theses cavities have a small particle or defect, it can degrade the performance of the cavity. The problem at hand is inspecting the cavity for defects, little bubbles of niobium on the surface of the cavity. Thousands of pictures have to be taken of a single cavity and then looked through to see how many defects were found. A C + + program with Open Source Computer Vision (OpenCV) was constructed to reduce the number of hours searching through the images and finds all the defects. Using this code, the SRF group is now able to use the code to identify defects in on-going tests of SRF cavities. Real time detection is the next step so that instead of taking pictures when looking at the cavity, the camera will detect all the defects.

    Research has shown that the risk of hot spots in the drinking water pipes is very high. Hot spots are, for example, caused by central heating pipes that are too close to the water pipes. The water pipes may be 25 C for a long period, thus creating the risk of legionella growth. The various disciplines need to be careful in the design stage and building stage to prevent such situations from occurring. [Dutch] Onderzoek heeft uitgewezen dat het risico op 'hotspots' in de drinkwaterleidingen erg groot is. Hotspots worden bijvoorbeeld veroorzaakt door cv-leidingen die te dicht in de buurt van waterleidingen lopen. Die waterleidingen kunnen dan langdurig warmer zijn dan 25C en daardoor gevaar opleveren voor legionellagroei. Het vereist zorg van meerdere disciplines in de ontwerpfase en de bouwfase om deze situaties te vermijden.

    2006-01-01

    Full Text Available Differential effect of plant growth regulators and additives in proliferation of 18-month-old calli of Ananas comosus L. cv. Moris were assessed in vitro. The proliferation of callus relied on the growth regulators and additives. Of the different auxins supplemented in the Murashige and Skoog (MS media, 32.22 μM α-naphthaleneacetic acid (NAA gave the highest mean fresh weight of callus (46.817 g. Medium supplemented with 2,4-dichlorophenoxyacetic acid (2,4-D was inferior to NAA, while b-naphthoxy acetic acid (BNOA and p-chlorophenoxy acetic acid (4-CPA were not effective in proliferating 18-months old callus. Addition of casein hydrolysate and coconut water to NAA supplemented medium showed better proliferation and production of callus. However, in terms of callus production, NAA at 32.22 μM was economically better.

    2007-05-02

    A formal compositional study of the proanthocyanidins of Vitis vinifera L. cv. Carménère was conducted in this work. We first characterized the polymeric proanthocyanidins of Carménère skins, seeds, and wines. In addition, the wine astringency was analyzed and compared with Cabernet Sauvignon. Although Carménère wines had a higher proanthocyanidin concentration and mean degree of polymerization than Cabernet Sauvignon wines, the former wines were perceived as less astringent. The low seed/skin proportion in Carménère wines as compared to other varieties, as evidenced by the reduced number of seeds per berry and the higher amount of epigallocatechin subunits of Carménère wine proanthocyanidins, could explain this apparent paradox.

    Black rice is a type of pigmented rice with black bran covering the endosperm of the rice kernel. The main objective of the present study was to provide details information on the proximate composition of third generation of gamma irradiated black rice (Oryza sativa L. cv. Cempo ireng). In respect to the control, generally speaking, there were no significant changes of moisture, lipids, proteins, carbohydrates and fibers contents have been observed for the both gamma irradiated black rice. However, the 200-BR has slightly better nutritional value than that of 300-BR and the control. The mineral contents of 200-BR increased significantly of about 35% than the non-gamma irradiated black rice.

    Solid phase microextraction and simultaneous distillation-extraction combined with GC-FID, GC/MS, aroma extract dilution analysis and odour activity values were used to analyse volatile compounds from guava (Psidium guajava L. cv. Red Suprema) and to estimate the most odour-active compounds. The analysis led to the detection of 141 compounds, 121 of which were positively identified. The composition of guava fruit volatiles included 43 esters, 37 terpenes, 18 aldehydes, 16 alcohols, ten acids, six ketones, four furans and seven miscellaneous compounds. Seventeen odorants were considered as odour-active compounds, with (E)-β-ionone, ethyl hexanoate, ethyl butanoate, hexanal, (Z)-3-hexenal, hexyl acetate, (E)-2-hexenal and limonene contributing most to the typical guava aroma of this cultivar. © 2013 Society of Chemical Industry.

    Full Text Available TAF is the acronym for Articulated Forestry Tractor – a heavy vehicle uses in a logging operation for pulling cut trees out of a forest, in a process called “skidding”. TAF use a cardan shafts transmission from the gear box (CV to distribution box (CD. The distribution box split the movement thru axels or winch. The study applied the cardan theory on a specific case and based on the numeric results a few design modifications are proposed for reducing the angular velocity pulse on the CD input shaft. Theoretical results may have a significant importance in practice, impacting the reduction of transmission noise and vibrations - already claimed in the case of the distribution box for the current constructive solution. An original AutoLISP program are made in order to analyze and optimize the transmission, with graphical results.

    Elżbieta Kielak

    2013-12-01

    Full Text Available Changes in inhibitor activity in the onion bulbs (Allium cepa L. cv. Sochaczewska during storage were investigated. Onions were dried under an umbrella roof until October 15th or November 15th and thereafter stored in a cold-room at 0-1°C until May 15th. The activity of inhibitors fluctuated markedly during the storage period. At least two peaks and two decreases of inhibitor activity were observed. The weather conditions seemed to strongly influence the level and the date of appearance of inhibitors in onions. Higher inhibitor activity is usually connected with better storage and less sprouting of onions during storage. Prolonged drying under an umbrella roof enhanced onion quality after storage only in these cases when it actually improved the drying of onions.

    The objective of this research was to study the usefulness of nootkatone as a senescence indicator for Rouge La Toma cv. grapefruit (Citrus paradisi Macf.), simulating different treatments that included the normal postharvest handling of citrus fruits: temperature conditioning, cold storage, shipment periods to overseas markets such as Japan and the U.S., marketing conditions, and storage at nonchilling temperature (control treatments). The highest nootkatone levels, determined by GLC-MS analyses, were detected in fruits subjected to control treatments. No significant differences were observed in nootkatone levels between treatments either with or without temperature conditioning prior to the start of the cold storage. Levels of nootkatone increased throughout time for all assayed treatments. The linear regressions of nootkatone levels showed correlation coefficients of 0.80 and 0.83 with storage time (29 and 42 days, respectively). Therefore, nootkatone appears to be a good indicator of senescence for Rouge La Toma grapefruit.

    Full Text Available ABSTRACTThe limited access and the scarcity of good quality water for agriculture are some of the major problems faced in agricultural areas, particularly in arid and semiarid regions. The aim of this study was to evaluate the quality of watermelon seedlings (cv. Crimson Sweet, irrigated with different concentrations of biosaline water of fish culture. The experimental design was completely randomized with five treatments, corresponding to biosaline water at different concentrations (0, 33, 50, 67 and 100%, and four replicates of 108 seedlings. Watermelon seeds were sown in plastic trays filled with commercial substrate and irrigated with different solutions of biosaline water. Seedlings were harvested for biometric analysis at 14, 21 and 28 days after sowing. The use of biosaline water did not affect emergence and establishment of seedlings until 14 days after sowing, the period recommended for transplantation. However, the use of biosaline water affected the development of seedlings with longer exposure time.

    Lamiaceae plants mostly accumulate active ingredients in their leaves. The subfamily Nepetoideae, including the genus Mentha L., is characterized by the presence of essential oil and antioxidant phenolics, chiefly hydroxycinnamic acids with predominance of rosmarinic acid, and flavonoids. Mentha × piperita and M. spicata are the most broadly used mints in both medicine and industry, while M. x villosa is less known in our country. Herbal drugs in the form of leaves are usually analysed unpartitioned, while single leaves insertions have only been studied occasionally. Therefore, the aim of this work was the quantification of the active compounds content in the leaves pairs of Mentha × villosa Huds. cv. Snežná, using pharmacopoeial methods: total hydroxycinnamic derivatives expressed as rosmarinic acid (THD) and luteolin-type flavonoids. THD content ranged from 6.7% to 9.4% in the leaves pairs water extracts, and from 6.6% to 14.0% in methanol extracts. Flavonoids contents, expressed as luteolin-7-O-glucoside, ranged from 4.0% to 8.8% in water extracts, and from 4.0% to 10.5% in methanol extracts. Antioxidant activity (DPPH) expressed as SC50 ranged from 10.2 to 16.9 μg.ml-1 (drug dry weight) in water extracts, and from 10.7 to 21.6 μg.ml-1 in methanol extracts. The highest content of phenolic compounds as well as the highest antioxidant activity were found to be in the top sheet, while the lowest content of phenolic compounds and lowest antioxidant activity were detected in the leaves of the middle stem part.Key words: Mentha × villosa Huds cv.

    The commonly known alternate bearing, i.e. year-to-year change of large and small yields of fruit tree crops worldwide, is often induced by abiotic stress such as late frost, which will eliminate flowers or fruitlets. This study presents an alternative form, biotic biennial bearing, i.e. change of large and small yields of the same trees within the same tree row in the same year. Three methods were developed or modified for the analysis of the number of flower clusters and yield of 2086 apple (Malus domestica Borkh.) cv. 'Elstar' trees. The first method, i.e., based on intersect between yield in year x and year x+1 and flower clusters in year x, yielded 91-106 flower clusters, whereas the second method, i.e., mean yield in year x and year x+1, resulted in a range of 72-133 flower clusters, or 9.6kg/tree necessary for sustainable cultivation of apple cv. 'Elstar'. The third 'biennial bearing index' (BBI), was calculated in three ways as the ratio of differences in tree yields to cumulative tree yield, for individual trees (rather than orchard average) to demonstrate the tree-to-tree alternation. A scheme for the possible underlying regulatory mechanisms was developed, which includes potential elicitors such as light deprivation and subsequent lack of flower initiation, are discussed as a possible result of polar basipetal GA7 transport, cytokinin level in the xylem and phloem and down-regulation of the gene expression of the flowering gene. Suggested countermeasures included early chemical or mechanical thinning. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    The investigation was carried out at Germplasm Centre (BAU-GPC, Bangladesh Agricultural University, during March to July 2016 in order to investigate the effect of pre-harvest fruit bagging on post-harvest quality of guava cv. Swarupkathi. Four different bagging materials viz. brown paper bag, white paper bag, white polythene bag, black polythene bag included for the study and uncovered fruits were used as control treatment. The experiment was laid out in randomized complete block design with three replications. Fruit bagging treatments showed significant effects on different parameters studied. It was observed that fruit size, fruit weight, vitamin C concentration, and moisture content increased due to fruit bagging. Fruits were gained maximum in size (6.59 cm length, 5.86 cm diameter and weight (164.26 g under white paper bag followed by white polythene bag (131.3g. The skin color of fruits was very attractive in case of white paper bag than that of other treatments. Total soluble solid concentration of the fruit was found maximum (12.33% Brix under brown paper bag while maximum vitamin C concentration (162.14 mg 100 g-1 was recorded under white paper bag. Uncovered fruits showed maximum total sugar, non-reducing sugar, reducing sugar concentrations (10.13%, 6.05%, 4.08%, respectively.The results revealed that fruit bagging in general, improved the growth and quality of guava fruits as compared to control. Among the various fruit covering materials, white paper bag was found to be the best for overall improvement of physical and chemical quality of guava cv. Swarupkathi.

    Decent optical photometry of the canditate magnetic CV Paloma has uncovered three persistent periods at 157, 146, and 136 min, which we interpret as the manifestation of the orbital motion of the system, the white dwarf's spin, and a related side-band frequency of the other two. All three periodicities are caused by a double-humped modulation of about 1 mag appearing only at certain fractions of the beat cycle, and it probably originates from one or two accretion spots. Our data is consistent with two plausible solutions, with the spin period being either 146 or 136 min. The appearance of a corresponding spin-folded light curve suggests two different scenarios, for which either pole switching between two diametrically opposed accretion regions (for P_spin = 146 min) or pole migration of one single spot (with P_spin = 136 min) is the preferred accretion mode. Complementary ROSAT X-ray observations and low-resolution spectroscopy provide supporting evidence of the magnetic nature of the object. Depending on the choice of the spin period, the degree of asynchronism with respect to the orbital period is 7% or 14%, implying a beat period of 0.7 or 1.4 days. Thus, the source populates the gap between the near-synchronous polars (Paloma is a key object for magnetic CV evolution: it might be the first bona fide transition object between the DQ Her and AM Her system with a white dwarf currently in the process of synchronisation.

    Full Text Available Rooting and acclimatization are limiting steps in plant micropropagation, especially in woody plant species. This study aimed to evaluate the IAA and IBA effect on the in vitro rooting and acclimatization of micropropagated shoots of Japanese plum (Prunus salicina Lindl. cv. América. Shoots from 3 to 4 cm long were inoculated in MS medium with half salt and vitamin concentrations (MS/2 added with IAA and IBA (0, 0.25, 0.5, 0.75 and 1 mg L-1. After a 20-day period in in vitro cultivation, the shoots were evaluated, and then transferred to a greenhouse, and evaluated after 30 days. At the end of the in vitro cultivation period, no significant interactions were observed for number of roots per shoot and rooting percentage, but a significant effect was recorded for auxin type only, for which shoots grown in media added with IBA showed high values - 0.87 and 41.95%, respectively. A linear increase response from 1.45 to 5.75 cm was verified for root length of shoots cultivated in IBA medium; however, no significant effect was observed, and a 0.86 cm average root length per shoot grown in medium added with IAA was found. After 30 days of acclimatization period, the largest survival percentage was obtained from shoots cultivated in medium with 1 mg L-1 of IBA and IAA (88% and 92%, respectively. Although, IBA provided the highest in vitro rooting, most of the surviving shoots were those originated in IAA-added medium, probably because IBA promoted longer fibrous roots, less appropriate for transplant and soil fixation, as they are easily damaged. It was concluded that in vitro rooting with the addition of the highest IAA concentration (1 mg L-1 provided the greatest plant survival during the acclimatization period of the Japanese plum cv. América.

    The aim of this study was to assess the effect of different irrigation strategies on the sensory quality of virgin olive oil VOO) from the cv. cobrancosa- integrated into a protected denomination of origin of Azeite de Tras-os-Montes in the Northeast of Portugal. Three irrigation treatments were applied: (T2)-full irrigation, which received a seasonal water equivalent of 100% of the estimated crop evapotranspiration (ET{sub c}), (T1)-continuous deficit irrigation (30% ETc) and (T0)- rainfed treatment. Data were collected from two consecutive crop years (2005-2006). Olive oil samples were analyzed for volatiles by GC-MS and the results compared with sensory evaluation data. Total volatile compounds tended to decrease with the amount of water applied. The characteristics pungent and bitter were more pronounced in olive oils from T0 and T1, which had higher polyphenolic concentrations, with a strong positive relationship with this variable and the bitter attribute. The Principal Components Analysis clearly separates the three olive oils from 2005, the driest year, and aggregates into a single group the three samples from 2006, suggesting no effect of irrigation on volatile compounds in years with a rainy spring and a marked effect in years with severe drought, suggesting that the effect of the trees’ water status on these variables occurs throughout the crop season and not just during the oil accumulation phase. In general, olive oil from the cv. Cobrançosa is more bitter than pungent and has a typical nutty sensory attribute shown by a strong positive relationship between benzaldehyde and the sensory notes of almonds and nuts.

Para isso, as sementes foram germinadas em meio MS semi-sólido contendo BAP ou ANA e sem esses reguladores de crescimento. As sementes permaneceram nesses meios por um, dois, três e quatro dias, sendo então seus cotilédones inoculados em meio MS contendo diferentes concentrações de BAP (0,5; 0,9; 1,5 e 2,0mg L-1. As maiores taxas de regeneração ocorreram nos cotilédones oriundos de sementes mantidas durante um e dois dias nos meios contendo 0,5 e 0,9mg L-1 de BAP. O aumento da permanência dos explantes nos meios de germinação e as elevadas concentrações de BAP nos meios de regeneração diminuíram a capacidade organogênica dos explantes e incrementaram a formação de calos.The aim of the present study was to optimize a cv. Gaucho melon cotyledon explant regeneration protocol, evaluating the germination media composition and the explant exposition period in these media. For this purpose, seeds were germinated in semi-solid MS medium containing either BAP or ANA, and without growth regulators. The seeds were kept in these media for one, two, three or four days; afterwards, their cotyledons were inoculated in MS medium containing different BAP concentrations (0.5; 0.9; 1.5 and 2.0mg L-1. The highest regeneration rates occurred with cotyledons from seeds which had been kept for one or two days in media containing 0.5 and 0.9mg L-1 BAP. Both the increase in the explant exposition time in germination media and high BAP concentrations in regeneration media decreased explant organogenic capacity, and increased callus formation.

Um dos aspectos mais importantes na produção de alimentos da atualidade é a redução no uso de agroquímicos, com menor contaminação do ambiente e riscos reduzidos de resíduos. Este trabalho visou a comparar os sistemas de Produção Convencional (PC e Integrada (PI de pêssegos e foi realizado no ano de 2001, no município de São Jerônimo - RS, latitude 30°05'52" S, longitude 51°39'08" W e altitude de 46 metros. Áreas de um pomar comercial da cv. Marli foram avaliadas em relação às principais práticas de manejo da planta e do solo, controle fitossanitário, aspectos econômicos, bem como à qualidade da fruta. Na área conduzida sob PI, foram utilizadas as práticas de manejo preconizadas pelas Normas de Produção Integrada de Pêssegos (NPIP e, na área conduzida no sistema de PC, as plantas foram manejadas de acordo com as práticas comumente utilizadas pelo produtor. A produção de pêssegos, em ambos os sistemas, não foi afetada. Na área de PI, houve menor número de pêssegos por planta; entretanto, as frutas apresentaram maior peso médio. A maioria dos pêssegos da PI foram classificados como CAT I (diâmetro superior a 57 mm. As frutas produzidas na PC são, na maioria, de CAT II (de 48 a 57 mm. A qualidade pós-colheita não apresentou diferenças em relação à acidez, firmeza e cor. Com base nestes resultados, podemos concluir que é possível produzir pêssegos de qualidade com produtividade no sistema de PI.The peach-trees cultivation is a very economic important activity in South of Brazil, where highlights the State of Rio Grande do Sul as the largest Brazilian producer.

No verão e no outono, foram visualizados, respectivamente, 28 e 24 pontos, sorteados pelos tratamentos experimentais, semelhantes quanto à altura do dossel e à cobertura do solo, após intenso pastejo de uniformização. O perfilhamento da gramínea, intenso na primeira semana, decresceu nas duas semanas seguintes e praticamente cessou a partir da quarta semana. A IRFA evoluiu assintoticamente, atingindo valores de 96% em ambas as estações. O IAF apresentou o mesmo padrão de resposta, com valores de 8 e 4 no verão e no outono, respectivamente. Em ambas as estações, a biomassa evoluiu de forma quadrática com o decorrer da rebrotação. A EUR, mais alta no verão que no outono, decreceu e seus respectivos valores foram 1,76 e 0,54gMS/MJ, em razão da menor precipitação pluviométrica desse período. A eficiência de crescimento do dossel, medida pela TCR, mais alta no verão que no outono e decresceu assintoticamente durante a rebrotação, em ambos os períodos. Enquanto a TAL reduziu durante o período de rebrotação, a RAF aumentou até um ponto de máximo, tanto no verão como no outono

    Full Text Available Abstract Background We performed an environmental study of viruses infecting the symbiotic single-celled algae of Paramecium bursaria (Paramecium bursaria Chlorella virus, PBCV in Lake Biwa, the largest lake in Japan. The viruses detected were all Chlorella variabilis virus (CvV = NC64A virus. One of them, designated CvV-BW1, was subjected to further characterization. Results CvV-BW1 formed small plaques and had a linear DNA genome of 370 kb, as judged by pulsed-field gel electrophoresis. Restriction analysis indicated that CvV-BW1 DNA belongs to group H, one of the most resistant groups among CvV DNAs. Based on a phylogenetic tree constructed using the dnapol gene, CvV was classified into two clades, A and B. CvV-BW1 belonged to clade B, in contrast to all previously identified virus strains of group H that belonged to clade A. Conclusions We conclude that CvV-BW1 composes a distinct species within C. variabilis virus.

    Vection (V) refers to the compelling visual illusion of self-motion experienced by stationary individuals when viewing moving visual surrounds. The phenomenon is of theoretical interest because of its relevance for understanding the neural basis of ordinary self-motion perception, and of practical importance because it is the experience that makes simulation, virtual reality displays, and entertainment devices more vicarious. This experiment was performed to address whether an optokinetically induced vection illusion exhibits monotonic and stable psychometric properties and whether individuals differ reliably in these (V) perceptions. Subjects were exposed to varying velocities of the circular vection (CV) display in an optokinetic (OKN) drum 2 meters in diameter in 5 one-hour daily sessions extending over a 1 week period. For grouped data, psychophysical scalings of velocity estimates showed that exponents in a Stevens' type power function were essentially linear (slope = 0.95) and largely stable over sessions. Latencies were slightly longer for the slowest and fastest induction stimuli, and the trend over sessions for average latency was longer as a function of practice implying time course adaptation effects. Test-retest reliabilities for individual slope and intercept measures were moderately strong (r = 0.45) and showed no evidence of superdiagonal form. This implies stability of the individual circularvection (CV) sensitivities. Because the individual CV scores were stable, reliabilities were improved by averaging 4 sessions in order to provide a stronger retest reliability (r = 0.80). Individual latency responses were highly reliable (r = 0.80). Mean CV latency and motion sickness symptoms were greater in males than in females. These individual differences in CV could be predictive of other outcomes, such as susceptibility to disorientation or motion sickness, and for CNS localization of visual-vestibular interactions in the experience of self-motion.

    The excess salt, usually NaCl, inhibits potato plant growth and decreases tubers yield. The use of gamma irradiation to induce new mutants in potato cv. Diamant through tissue culture technique was the main task of this study. Sterilized meristemic tips of potato tubers were cultured on aseptic solid MS-medium, pH 5.7, and were incubated at 20 ± 2 d eg C and 16 hrs day length of 3000-Lux light intensity, to produce virus-free plantlets. Micro-propagation started after 6-8 weeks and plantlets were sub-cultured every 3-4 weeks to increase plantlets population. Plantlets were exposed to 0, or 40 Gy, dose rate 27.7 rad / sec., using Co 60 source at the National Center for Research and Radiation Technology, Cairo, Egypt. Irradiated and unirradiated plantlets were transplanted into 60 ml liquid 1/2MS-medium, pH 5.7, and supplemented with 0, 2000 or 4000 ppm NaCl. And, they were incubated for 2 weeks under the same conditions of temperature and light till the new plantlets were grown up. Healthy plantlets were selected, and micro-propagated up to the sixth vegetative generation (M 1 V 6 ), under the same conditions of salinity and incubation conditions Thereafter, the plantlets were transferred to tuberization liquid 1/2MS-medium, supplemented with the same mentioned concentrations of NaCl, to obtain microtubers. The microtubers were collected after 6-8 weeks and preserved at 10 deg C for 3 months approximately, to break the dormancy. Sprouted microtubers were sown to obtain minitubers, and subsequently macrotubers. All cultures were performed in 30-cm pots in a protected greenhouse, and were irrigated with the same concentrations of NaCl. It could be elicited that cv. Diamant is salinity sensitive. This was evidenced by the decrease in the average number of tubers per plant and average fresh weight of tuber under salinity stress up 4000 ppm NaCl, comparing to unsaline control treatment. Potato plants, which still healthy and produced tubers under salinity stress up to

    Tomato (Solanum lycopersicum) fruit ripening implies that chloroplastic proteins are degraded and new proteins are synthesized. Supplementary nutrition is frequently required when tomato plants begin to fruit and continues until the end of the plant's life cycle. Ammonium assimilation is crucial in these fruit maturation and ripening processes. Glutamine synthetase (GS; EC 6.3.1.2), the main ammonium-fixing enzyme in plants, could not be detected in red fruits of several tomato varieties when growing under standard nutrition. In this paper, we analyze the influence of the nutritional status on the ammonium assimilation capacity of ripe tomato (cv. Micro-Tom) fruit. For this purpose, GS expression and protein profiles were followed in mature green and red fruits harvested from plants grown under standard or supplemented nutrition. Under standard nutrient regime (weekly supplied with 0.5 x Hoagland solution) GS activity was found in chloroplasts (GS2) of mature green fruits, but it was not detected either in the chromoplasts or in the cytosol of red fruits. When plants were shifted to a supplemented nutritional regime (daily supplied with 0.5 x Hoagland solution), GS was found in red fruits. Also, cytosolic transcripts (gs1) preferentially accumulated in red fruits under high nutrition. These results indicate that mature green Micro-Tom fruits assimilate ammonia through GS2 under standard nutrition, while ripe red fruits accumulate GS1 under high nutrition, probably in order to assimilate the extra N-compounds made available through supplemented nutrition.

    Ficin (EC 3.4.22.3), a cysteine endoproteolytic protease in fig trees' latex, has multiple isoforms. Until now, no data on autolysis of individual ficins (ficin isoforms) are available. Following purification, ficins' autolysis was determined by HPLC chromatogram changes and ultrafiltrations at different temperatures and storage times. These results showed that the number of HPLC peaks in latex proteins purification of Ficus carica cv. Sabz varied from previous fig varieties or cultivars. Proteolytic activity of ficins was inhibited by specific cysteine protease inhibitors, confirming the participation of the cysteine residue in the active site. The zeta potential of the first two eluted peaks (I and II) was negative, while that of other peaks were positive. All ficins were susceptible to autolysis when stored at high temperatures. In contrast, only the last two ficins (B, C) were prone to autolysis at cold temperature after long storage period. The rate of degradation of the ficins was significantly increased with the increased storage time. The ficin (A) related to peak (III) had the highest and the lowest surface hydrophobic patches and ratio of autolytic to proteolytic activity, respectively. Copyright © 2012 Elsevier Ltd.

    Loquat cv. Mardan is a promising variety in loquat growing areas of northern Punjab and Khyber Pakhtoon Khwa. Loquat growers face serious issue of true to type plants availability. An attempt was made to explore different vegetative propagation techniques to find out most successful method for nursery industry. In the study propagation through cutting (during spring) and grafting during different suitable seasons (spring and monsoon) was examined. Cuttings were treated with different growth regulators to promote rooting. PBZ, IBA and their combinations were applied to the cuttings. Highest success percentage (40%) was achieved with PBZ. This limited success in rooting of cuttings was complete failure in getting plant survival at the end of the study. In the second phase of the experiment different grafting techniques i.e. tongue, cleft and side grafting were evaluated during two different seasons i.e., spring and monsoon. Cleft grafting in the months of March/ April proved to be most successful method in terms of success (70%), days taken for shoot growth, no. of leaves, shoots length, no. of branches. While in monsoon season side grafting was significantly better with a success of 85%. Overall, monsoon side grafting proved to be more successful than any other method. (author)

    Grapevine is one of the most economically important fruit crops. Molecular markers have been used to study grapevine diversity. For instance, simple sequence repeats are a powerful tool for identification of grapevine cultivars, while amplified fragment length polymorphisms have shown their usefulness in intra-varietal diversity studies. Other techniques such as sequence-specific amplified polymorphism are based on the presence of mobile elements in the genome, but their detection lies upon their activity. Relevant attention has been drawn toward epigenetic sources of variation. In this study, a set of Vitis vinifera cv Pinot noir clones were analyzed using the methylation-sensitive amplified polymorphism technique with isoschizomers MspI and HpaII. Nine out of fourteen selective primer combinations were informative and generated two types of polymorphic fragments which were categorized as "stable" and "unstable." In total, 23 stable fragments were detected and they discriminated 92.5 % of the studied clones. Detected stable polymorphisms were either common to several clones, restricted to a few clones or unique to a single clone. The identification of these stable epigenetic markers will be useful in clonal diversity studies. We highlight the relevance of stable epigenetic variation in V. vinifera clones and analyze at which level these markers could be applicable for the development of forthright techniques for clonal distinction.

    Full Text Available Chitosan, is non-toxic, biodegradable and biocompatible material, which can be used as edible coatings to maintain quality and enhance postharvest life of fruits and vegetables. In this study, the effect of chitosan at 0, 0.5, 1 and 2% concentrations on storage life of cucumber cv. "Zomorod" was investigated. After treatment and keeping in an incubator at 12 °C and 90% relative humidity, the fruits were assessed in 5-days intervals to determine parameters such as firmness, weight loss, vitamin C, titratable acidity, soluble solids and chlorophyll content. Experiment was performed as a split-plot design in time in a completely randomized design with three replications. The results of the experiment showed that chitosan coating, had a significant effect on all traits except titrable acidity. The lowest weight loss and the highest firmness were recorded with 1% chitosan treatment which significantly differed from the control. It is appeared that chitosan coatings could be used to increase the storage life of cucumber fruit and to maintain its quality for a longer period.

    Full Text Available This study was aimed to investigate the effect of heat treatment and shelf life on chilling injury of mango cv.Nam Dok Mai.The heat treatment of mango pulp during storage were determined by hot air oven set at 34 and 38°C for three intervals, as 24, 48, and 72 hours, then they were subsequently stored at 5°C for 10, 20, and 30 days to determine the appropriate shelf life. The findings showed that the symptom of mango fruit after chilling injury appeared within the 30th day of storage at 5°C. Several symptoms of mango fruit after chilling injury treatment were observed, i.e., pitting, browning on the skin, water soaking, and rapid rotting of the fruits that resulted in shorter shelf life. It was found that chilling injury mangoes had lower level of total soluble solid, higher disease incidence, and lower quality of fruit when compared with normal ripe-mango fruits at 25°C. Mango fruits treated at 34°C for either 24 or 48 hours, and at 38°C for 24 hours prior to cold storage at 5°C for 10 and 20 days showed a significant reduction in the chilling injury (CI index when compared to that of non-heated fruits. On the other hand, the heat treatment did not affect fruit weight loss, firmness, color changes, and water soaking at 5°C.

    The importance of ethylene in avocado ripening has been extensively studied. In contrast, little is known about the possible role of abscisic acid (ABA). The present work studied the effect of 1-methylcyclopropene (1-MCP) (0.3 μL L -1 ), e+® Ethylene Remover and the combination thereof on the quality of imported avocado cv. Hass fruit stored for 7 days at 12 °C. Ethylene production, respiration, firmness, colour, heptose (C7) sugars and ABA concentrations in mesocarp tissue were measured throughout storage. Treatment with e+® Ethylene Remover reduced ethylene production, respiration rate and physiological ripening compared with controls. Fruit treated with 1-MCP + e+® Ethylene Remover and, to a lesser extent 1-MCP alone, had the lowest ethylene production and respiration rate and hence the best quality. Major sugars measured in mesocarp tissue were mannoheptulose and perseitol, and their content was not correlated with ripening parameters. Mesocarp ABA concentration, as determined by mass spectrometry, increased as fruit ripened and was negatively correlated with fruit firmness. Results suggest a relationship between ABA and ethylene metabolism since blocking ethylene, and to a larger extent blocking and removing ethylene, resulted in lower ABA concentrations. Whether ABA influences avocado fruit ripening needs to be determined in future research. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

    The C-V characteristics of n-channel JFET have been measured under different environmental conditions of temperature up to 140 deg. C and {gamma}-rays up to 100 kGy. For low bias voltage and frequency, the input capacitance, C{sub iss}, is shown to be a direct function of temperature. On the other hand, its value was shown to decrease from 11.68 down to 8.17 nF due to {gamma}-exposure up to 100 kGy. The y-parameters of common source amplifier were calculated under the influence of temperature and {gamma}-rays. The results show that the susceptance component of the admittance increases due to increase in temperature, while decreasing after {gamma}-exposure. Considering the cutoff frequency f{sub T0}, it is clear that as the temperature increases from 30 up to 140 deg. C, f{sub T0} dropped from 47 MHz down to 5 MHz, measured at 0.8 V. On the other hand its value was shown to increase from 43 MHz up to 102 MHz, measured at the same bias voltage, due to {gamma}-exposure up to 100 kGy.

    There is increasing interest in the distribution of sustainable gases (H2, H2/CO, CH4/CO2) and imported gases, such as LNG. The composition of these 'new' gases can differ greatly from the traditional distributed gases. The combustion characteristics may cause undesired effects in household appliances. One of the solutions is to develop equipment that can accept a wide range of gases and mixtures thereof. To this end, within the EDGaR-program (Energy Delta Gas Research) the project 'new gas sensors' is started by the Energy Research Centre of the Netherlands (ECN), Delft University of Technology (TUD) and DNV-KEMA/Gasunie to develop a boiler in which the new gases can be used [Dutch] Er is toenemende interesse in de distributie van duurzame gassen (H2 , H2/CO, CH4/CO2 ) en geimporteerde gassen, zoals LNG.

    Directory of Open Access Journals (Sweden)

    Iván Balic

    Full Text Available Ripening is one of the key processes associated with the development of major organoleptic characteristics of the fruit. This process has been extensively characterized in climacteric fruit, in contrast with non-climacteric fruit such as grape, where the process is less understood. With the aim of studying changes in gene expression during ripening of non-climacteric fruit, an Illumina based RNA-Seq transcriptome analysis was performed on four developmental stages, between veraison and harvest, on table grapes berries cv Thompson Seedless. Functional analysis showed a transcriptional increase in genes related with degradation processes of chlorophyll, lipids, macromolecules recycling and nucleosomes organization; accompanied by a decrease in genes related with chloroplasts integrity and amino acid synthesis pathways. It was possible to identify several processes described during leaf senescence, particularly close to harvest. Before this point, the results suggest a high transcriptional activity associated with the regulation of gene expression, cytoskeletal organization and cell wall metabolism, which can be related to growth of berries and firmness loss characteristic to this stage of development. This high metabolic activity could be associated with an increase in the transcription of genes related with glycolysis and respiration, unexpected for a non-climacteric fruit ripening.

    Plant tissues such as somatic embryos, apical shoot tips, axillary shoot buds, embryogenic calli, and protocom-like bodies are potential micropropagules that have been considered for creating synthetic seeds. In the present study, 3-5 mm microshoots of Oryza sativa L. Cv. MRQ 74 were used as explant sources for obtaining synthetic seeds. Microshoots were induced from stem explants on Murashige and Skoog (MS) medium supplemented with 1.5 mg/L benzylaminopurine (BAP). They were encapsulated in 3% (w/v) sodium alginate, 3% sucrose, 0.1 mg/L BAP, and 0.1 mg/L α-Naphthalene acetic acid (NAA). Germination and plantlet regeneration of the encapsulated seeds were tested by culturing them on various germination media. The effect of storage period (15-30 days) was also investigated. The maximum germination and plantlet regeneration (100.0%) were recorded on MS media containing 3% sucrose and 0.8% agar with and without 0.1 mg/L BAP. However, a low germination rate (6.67%) was obtained using top soil as a sowing substrate. The germination rate of the encapsulated microshoots decreased from 93.33% to 3.33% after 30 days of storage at 4°C in the dark. Therefore, further research is being done to improve the germination rate of the synthetic seeds.

    A haemagglutinin was purified from Japanese Hokkaido red beans (Phaseolus vulgaris cv. Hokkaido red bean) with a procedure that included three chromatographic media. Haemagglutinating activity was adsorbed on DEAE cellulose, Affi-gel blue gel and Mono S. The pure haemagglutinin was a homodimer and each subunit was around 30 kDa in molecular mass. The haemagglutinating activity of this agglutinin could not be inhibited by a variety of simple sugars at 200 mmol L(-1) concentration including alpha-L-fucose, D(+)-galactose, D(+)-glucose, D(+)-glucosamine, D(-)galactosamine, galacturonic acid, (+)-lactose, D(+)-melibose, L(-)-mannose, D(+)-mannose, D-mannosamine, D(+)-raffinose, L-rhamnose, (+)-xylose and galacturonic acid. The haemagglutinating activity was fully retained at pH 4-11 and at 0-80 degrees C, but was completely lost at extreme pH values (0-2 and 13-14) and at very high temperatures (90 degrees C and 100 degrees C). The haemagglutinin exhibited a weak mitogenic activity toward mouse splenocytes, a stronger anti-proliferative activity than Con A toward HepG2 (human hepatoma) cells and inhibited >80% of HIV-1 reverse transcriptase inhibitory activity at 3.3 micromol L(-1). It was devoid of anti-fungal activity. Hokkaido red bean haemagglutinin possesses a potent anti-proliferative effect on HepG2 cells. Copyright (c) 2009 Society of Chemical Industry.

    Sweet orange cv. Pera (Citrus sinensis L. Osbeck) harvested from July to November, is the most important cultivar in growing area and consumption in Brazil. To obtain mutants for many characteristics, one-year-old shoots were irradiated at 40 Gy of gamma-rays and the axillary buds were budded. After two cutting-backs, about 7,580 V3M1 plants were obtained. Total of 127 putative mutants were selected from these plants for further examination. The main purpose of this experiment was to obtain late ripening clones which have good fruit quality. These all plants were divided into 15 groups based on the characteristics and random blocks design with 5 replications, including one control plant in each block, was used. The plants were planted 4 X 7 meters and were grown in field condition without artificial irrigation. Ten fruits from each tree were used in evaluating the fruit characteristics such as contents of soluble solid (TSS), acidity, ratio of juice content and skin color, for four years. The data was analyzed by Dunnett test using SAS program. Six clones (9, 10, 16, 21, 58 and 84) were considered as late ripening mutants because they showed lower level of TSS or less ratio of juice content, comparing with the control, in more than one evaluation. The color of the skin of some mutants indicates that they have later ripening characteristics. Other agronomic characteristics are under evaluation in order to see if these mutants can be released as new cultivars

    ABSTRACT Trehalose-6-phosphate (Tre6P) is a precursor of trehalose, which is widespread in nature and greatly influences plant growth and development. Tre6P acts as a signal of carbon availability in many plants, but little is known about the function of Tre6P in rosaceous plants, which have specific sorbitol biosynthesis and transportation pathways. In the present study, Tre6P levels and Sorbitol:Tre6P ratios were analyzed in apple (Malus domestica, Borkh. cv. Gala). Tre6P levels were positively correlated with sorbitol content but negatively correlated with sucrose, glucose, and fructose content in developing fruit. However, under sorbitol-limited conditions, Tre6P levels were positively correlated with both sorbitol and sucrose. In the presence of different exogenous sugar supply, Tre6P levels increased corresponding with sorbitol, but this was not the case with sucrose. In addition, Tre6P content and sorbitol:Tre6P ratios were more highly correlated with ADP-glucose levels under sorbitol-limited conditions and fruit development stages, respectively. These results suggest that Tre6P is more closely related to sorbitol than other soluble sugars and has an important role in influencing carbon metabolism in apple. PMID:28069587

    Imported genetically modified (GM) canola (Brassica napus) is approved by Japanese law. Some GM canola varieties have been found around importation sites, and there is public concern that these may have any harmful effects on related species such as reduction of wild relatives. Because B. juncea is distributed throughout Japan and is known to be high crossability with B. napus, it is assumed to be a recipient of B. napus. However, there are few reports for introgression of cross-combination in B. juncea × B. napus. To assess crossability, we artificially pollinated B. juncea with B. napus. After harvesting a large number of progeny seeds, we observed false hybrids and metaxenia of seed coats. Seed coat color was classified into four categories and false hybrids were confirmed by morphological characteristics and random amplified polymorphic DNA (RAPD) markers. Furthermore, the occurrence of false hybrids was affected by varietal differences in B. napus, whereas that of metaxenia was related to hybridity. Therefore, we suggest that metaxenia can be used as a marker for hybrid identification in B. juncea L. cv. Kikarashina × B. napus. Our results suggest that hybrid productivity in B. juncea × B. napus should not be evaluated by only seed productivity, crossability ought to be assessed the detection of true hybrids. PMID:23136472

    Results of an experimental investigation of the contamination of air sampling inlets by aircraft emissions from the NASA CV-990 research aircraft are presented. This four-engine jet aircraft is a NASA facility used for many different atmospheric and meteorological experiments, as well as for developing spacecraft instrumentation for remote measurements. Our investigations were performed to provide information on which to base the selection of sampling locations for a series of multi-instrument missions for measuring tropospheric trace gases. The major source of contamination is the exhaust from the jet engines, which generate many of the same gases that are of interest in atmospheric chemistry, as well as other gases that may interfere with sampling measurements. The engine exhaust contains these gases in mixing ratios many orders of magnitude greater than those that occur in the clean atmosphere which the missions seek to quantify. Pressurized samples of air were collected simultaneously from a scoop located forward of the engines to represent clean air and from other multiport scoops at various aft positions on the aircraft. The air samples were analyzed in the laboratory by gas chromatography for carbon monoxide, an abundant combustion by-product. Data are presented for various scoop locations under various flight conditions.

    Full Text Available The heat event that occurred in many parts of Australia in 2009 was the worst on record for the past decade, with air temperatures exceeding 40oC for 14 days. Our aim was to assess the impacts of this heat event on vine performance, including ripening, yield and gas exchange of Vitis vinifera cv. Semillon grown in a Riverina vineyard. To assess the affect of high temperatures on Semillon grapevines, the vines were covered with a protective layer to reduce radiant heating and were compared with vines exposed to ambient conditions. The heat event had major effects on ripening; reducing the rate by 50% and delaying harvest ripeness and causing a high incidence of berry shrivel and sunburn. Yield was not affected. Photosynthesis was reduced 35% by the heat event while transpiration increased nearly 3-fold and was accounted for by increased stomatal conductance. The conclusion of this study was that heat events delayed ripening in Semillon berries and caused a significant reduction in berry quality. Strategies to minimise the radiant load during heat events are required and this study has confirmed a protective layer can reduce canopy temperatures and enhance berry quality.

    In this study, the effects of drought stress on pepino seedlings (Solanum muricatum cv. Miski) under natural greenhouse conditions were examined. The control plants were watered at field capacity, and the stress group was not watered. Samples were collected on the 6th, 12th, 24th and 36th days from the leaves of S. muricatum seedlings that, were exposed to drought stress. The relative water content, the total phenolic compounds, and the malondialdehyde, total photosynthetic pigments (chlorophyll a, chlorophyll b and carotenoids), and proline contents in these samples were determined. Depending on drought stress, the relative water content, the chlorophyll a, chlorophyll b and carotenoid contents, and the total chlorophylls were found to be lower in the stress group compared with the control group. In contrast, the total phenolic compounds (24th and 36th days) and the proline (12th, 24th and 36th days) levels increased significantly compared with the control group. In addition, a significant increase in the malondialdehyde contents was obtained on the 36th day in the stress group compared with the control group. Such studies may be important for evaluation of metabolic changes in pepino under the drought stress. (author)

    As part of the Binaries Are Not Always Neatly Aligned project (BANANA), we have found that the eclipsing binary CV Velorum has misaligned rotation axes. Based on our analysis of the Rossiter-McLaughlin effect, we find sky-projected spin-orbit angles of βp = -52° ± 6° and βs = 3° ± 7° for the primary and secondary stars (B2.5V + B2.5V, P = 6.9 days). We combine this information with several measurements of changing projected stellar rotation speeds (vsin i sstarf) over the last 30 yr, leading to a model in which the primary star's obliquity is ≈65°, and its spin axis precesses around the total angular momentum vector with a period of about 140 yr. The geometry of the secondary star is less clear, although a significant obliquity is also implicated by the observed time variations in the vsin i sstarf. By integrating the secular tidal evolution equations backward in time, we find that the system could have evolved from a state of even stronger misalignment similar to DI Herculis, a younger but otherwise comparable binary.

    Full Text Available Warehousing management problems that exist in the CV. ABB is the management of warehouses that are susceptible to manipulation of data, methods of work are still very manual such as recording a spare part only handwritten by the warehouse, frequent loss of spare parts in the warehouse, the bon false, and the lack of supervision instruments for oversee the spare parts in the warehouse. To overcome these problems, then made improvements through the implementation of warehouse management information system. Improvements in the form of procurement supervision instruments using the application PHP7 and MySQL, because the existence of the application makes it easy to keep an eye on spare parts in the warehouse, ranging from spare part comes in, spare part out, anyone who requests a part, stock of spare parts of existing in the warehouse, stock outs are used to help finance the manufacture purchase order, reports the spare parts that go into the warehouse of the supplier and request a report part. Not only is it a system of warehousing information can facilitate in making purchase order finance and carry out the approval of the request part of the user. Thus the system becomes more transparent.

    Esca is a destructive disease that affects vineyards leading to important losses in wine production. Information about the response of Vitis vinifera plants to this disease is scarce, particularly concerning changes in plant metabolism. In order to study the metabolic changes in Vitis plants affected by esca, leaves from both infected and non-affected cordons of V. vinifera cv. Alvarinho (collected in the Vinho Verde region, Portugal) were analysed. The metabolite composition of leaves from infected cordons with visible symptoms [diseased leaves (dl)] and from asymptomatic cordons [healthy leaves (hl)] was evaluated by 1D and 2D (1)H-nuclear magnetic resonance (NMR) spectroscopy. Principal component analysis (PCA) of the NMR spectra showed a clear separation between dl and hl leaves, indicating differential compound production due to the esca disease. NMR/PCA analysis allowed the identification of specific compounds characterizing each group, and the corresponding metabolic pathways are discussed. Altogether, the study revealed a significant increase of phenolic compounds in dl, compared with hl, accompanied by a decrease in carbohydrates, suggesting that dl are rerouting carbon and energy from primary to secondary metabolism. Other metabolic alterations detected comprised increased levels of methanol, alanine, and gamma-aminobutyric acid in dl, which might be the result of the activation of other defence mechanisms.

    A water-soluble pectic polysaccharide (MP-A40) was isolated and purified from Mosla chinensis Maxim. cv. Jiangxiangru for the first time, with a molecular weight of 32,600Da. MP-A40 was comprised of 68.63% galacturonic acid and 13.05% neutral sugar. In addition, arabinose, galactose, rhamnose, mannose and glucose composed the neutral sugar in a relative ratio of 4.94, 3.07, 2.13, 1.62 and 1.29% of the dry weight of MP-A40, respectively. Structural characterization of MP-A40 was investigated by methylation analysis and 1D/2D NMR spectroscopy. From the results, the structure of MP-A40 was revealed as follows: 1,4-linked α-d-GalpA and 1,4-linked α-d-GalpA6Me interspersed with rare t-Araf (0.60%), t-Rhap (1.67%) and t-GalpA (10.15%). Esterification assay showed that about 32% of the carboxylic groups in GalA residues existed as methyl ester. In addition, MP-A40 could inhibit the growth of human leukemic cell line K562 and stimulate nitric oxide production from RAW 264.7 macrophages both in dose-dependent manners.

    The use of ionizing irradiation or the use of hot water treatment (HWT) has been demonstrated as a successful commercial phytosanitary treatment during the past two decades. Several countries currently use this technology for commercial treatments to meet plant quarantine requirements. However, hydrothermal treatment has been found to significantly affect the firmness of ;Ataulfo; mango fruit, the susceptibility to damage by cold and it also accelerates their maturation. In this study, we focused on the effect of irradiation doses on the sensorial quality and the physiochemical properties of mango cv ;Ataulfo; compared with the traditional hot water treatment. We found that doses of 150 Gy and 300 Gy of gamma radiation can be applied successfully as well as the hot water treatment. There was no significant difference in between irradiation treatments in terms of weight loss, external and internal color, pH, soluble solids, titratable acidity and firmness, and consumer's acceptance. There was no adverse effect of color appearance, odor and flavor, indicating that consumers will have the willingness to buy and consume irradiated mangoes. Irradiation of mangoes can be a successful post-harvest treatment as an alternative to the hot water treatment.

    Full Text Available The experiment aimed to understand the effect of grazing period on morphology and nutritive value of deferred Brachiaria decumbens cv. Basilisk pasture and on hand-plucking sample with cattle. Subdivided plots were used according to a randomized block design with two replicates. Four grazing periods (1, 31, 57 and 88 days and two forage samples (available in pasture (AP and obtained by hand-plucking (HP were studied. The live leaf laminae (LLL, potentially digestible neutral detergent fiber (PDNDF, potentially digestible dry matter (PDDM and crude protein (CP levels were higher and dead leaf laminae (DLL, and dead stem (DS, neutral detergent fiber (NDF and indigestible NDF percentages were lower in sample of HP in relation to forage AP. The grazing period decreased linearly the LLL, PDNDF, PDDM percentages, as well as increased linearly DS and indigestible NDF levels in forages. The potential selectivity indexes (PSI of LLL and indigestible NDF increased linearly with grazing period. The PSI of live stem was smaller and the PSI of CP was higher in interim periods of grazing. The reduction in deferring period results in B. decumbens with better morphological composition and nutritional value, which favors the animal selectivity.

    Full Text Available Lettuce is the most popular of the leafy vegetables. It is known worldwide and its consumption occurs mainly in the natural form. The objective was to evaluate the effect of macronutrient omission on the growth and nutritional status of the lettuce cv. Veronica, and to describe the visual symptoms of nutritional deficiency. The treatments complete consisted of the solution and the individual omission of N, P, K, Ca, Mg and S, under a completely randomized design with three replications. Plants were grown in Hoagland & Arnon, in pots (8L. At 56 days after transplant we evaluated plant height, leaf number, leaf area, SPAD index, dry matter of shoots, roots and whole plant, levels of macronutrients in shoots and roots, and the nature of nutritional disorders. The omission of nutrients affected the growth variables. The nutrients found in lettuce plants from nutrient solution and the complete omission in the shoot were, respectively, N= 23.2 to 9.5, P= 5.4 to 1.3, K= 58,9 to 3.2, Ca= 12.1 to 3.6, Mg= 5.5 to 0.7 and S= 3.2 to 1.5g.kg-1. The omission of macronutrients caused quality losses, since it affected the nutrition of the vegetables and this resulted in morphological changes, reflected as symptoms of deficiency for each nutrient.

    Somatic embryogenetic capability and changes in polyamine level and their relationship were analyzed using the long-term (8 years) subcultured calli of Citrus sinensis Osb. cv. Valencia as materials. The results showed that endogenous polyamine contents in embryogenic calli were higher than those in non-embryogenic calli, and the embryogenetic capability was positively correlated to the levels of endogenous polyamines. When the calli were transferred to a differentiation medium, the putrescine content rapidly increased and reached a peak, then fell gradually. Applying exogenous putrescine raised the embryogenesis frequency and endogenous putrescine level. It indicated that increase in putrescine content at early stage of differentiation promoted embryogenesis. With the development of somatic embryo, spermidine content reached its the highest level at globular embryo stage, spermine content rose and reached a peak at a later stage of globular embryo development. Furthermore, changes of the putrescine, spermidine and spermine contents during somatic embryogenesis were similar in Valencia calli which had different ploidy levels, but their contents decreased following the increasing of ploidy level. Changes in arginine decarboxylase activity were positively correlated to the polyamine levels, which suggest that the later is a key factor in regulating the polyamine levels during somatic embryogenesis in citrus plants.

  6. Role of Ethylene in Lactuca sativa cv ;Grand Rapids' Seed Germination.

    Abeles, F B

    1986-07-01

    Promotion of thermoinhibited (30 degrees C) lettuce (Lactuca sativa cv ;Grand Rapids') seed germination by ethylene is similar to the action of the gas in other hormonal systems. Ethylene was more active than propylene and ethane was inactive. An inhibitor of ethylene production, aminoethoxy-vinylglycine, reduced ethylene evolution and germination. Inhibitors of ethylene action such as, 5-methyl-7-chloro-4-ethoxycarbonylmethoxy-2,1,3-benzothiadiazole, 2,5-norbornadiene, and silver thiosulfate inhibited germination and the effect was reversed by the addition of ethylene to the gas phase. The action of ethylene appears to be due to the promotion of radial cell expansion in the embryonic hypocotyl. The action of N6-benzyladenine and fusiccocin, which also overcome thermoinhibition, appears to be due to a promotion of hypocotyl elongation. None of the germination promoters studied appeared to function by lowering the mechanical resistance of the endosperm to embryonic growth. Data presented here are consistent with the view that ethylene plays a role in lettuce seed germination under thermoinhibited and normal conditions.

    Avocado (Persea americana Mill, cv. Hass) fruit ranks tenth in terms of the most important products for Mexico. Avocado products are quite unstable due to the presence of oxidative enzymes such as polyphenol oxidase and peroxidase. The present study is to characterize the activity of purified avocado peroxidase from avocado in order to ascertain the biochemical and kinetic properties and their inhibition conditions. Purification was performed by Sephacryl S 200 HR gel filtration chromatography and its estimated molecular weight was 40 kDa. The zymogram showed an isoelectric point of 4.7. Six substrates were tested in order to ascertain the affinity of the enzyme for these substrates. The purified peroxidase was found to have low Km (0.296 mM) and high catalytic efficiency (2688 mM(-1) s(-1)) using 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid), optimum activity being reached at 51°C, pH 3.8. The addition of dithiothreitol, β-mercaptoethanol, ascorbic acid, sodium azide, L-cysteine and Tween-20 had high inhibitory effects, while metals ions such as Cu(+), Fe(2+) and Mn(2+) had weak inhibitory activity on purified avocado peroxidase. The purified avocado peroxidase exhibits high inhibition (Ki = 0.37 µM) with 1.97 µM n-propyl gallate using ABTS as substrate at 51°C, pH 3.8 for 10 min. © 2013 Society of Chemical Industry.

    The oxidation of chlorophyll a (chl a) catalysed by peroxidase (POD) from mesocarp of the olive fruit (Olea europaea L., cv Hojiblanca) in the presence of H2O2 and 2,4-dichlorophenol (2,4-DCP), is characterised via the individualised quantification of the products of the enzymatic reaction using a new methodology of HPLC-UV spectrometry. This innovation has allowed the discovery that, in addition to 13(2) OH chl a and 15(1) OH lactone chl a, which are the first products of POD on chl a, the reaction process sequentially creates another series of oxidised chlorophyll derivatives which have not been previously described. Their origins have been linked to POD activity in the presence of 2,4-DCP. Likewise, a study of the effect of the concentration of the various cosubstrates on the POD reaction rate demonstrated that the correct establishment of the relative concentrations of the same ([H2O2]/[2,4-DCP]/[Chl]=1:3:0.02) is crucial to explaining inhibition effects by substrates and carrying out optimum measurements. Therefore, new essential parameters for the determination of POD activity on a chlorophyll substrate are established. Copyright © 2013 Elsevier Ltd. All rights reserved.

    Mango pulp contains ascorbic acid, carotenoids, polyphenols, terpenoids and fiber which are healthy and could protect against colon cancer. The aim of this study was to evaluate the antiproliferative and preventive capacity of an aqueous extract of Mangifera indica cv. Azúcar on a human colon adenocarcinoma cell line (SW480) and in a rodent model of colorectal cancer, respectively. The content of total phenolics, flavonoids and carotenoids were also analyzed in the extract. SW480 cell growth was inhibited in a dose and time dependent manner by 22.3% after a 72h exposure to the extract (200 µg/ mL). Colon carcinogenesis was initiated in Balb/c mice by two intra-peritoneal injections of azoxymethane (AOM) at the third and fourth week of giving mango in drinking water (0.3%, 0.6%, 1.25%). After 10 weeks of treatment, in the colon of mice receiving 0.3% mango, aberrant crypt foci formation was inhibited more than 60% (p=0,05) and the inhibition was dose-dependent when compared with controls receiving water. These results show that mango pulp, a natural food, non toxic, part of human being diet, contains bioactive compounds able to reduce growth of tumor cells and to prevent the appearance of precancerous lesions in colon during carcinogenesis initiation.

    Transgenic plastids offer unique advantages in plant biotechnology, including high-level foreign protein expression. However, broad application of plastid genome engineering in biotechnology has been largely hampered by the lack of plastid transformation systems for major crops. Here we describe the development of a plastid transformation system for lettuce, Lactuca sativa L. cv. Cisco. The transforming DNA carries a spectinomycin-resistance gene (aadA) under the control of lettuce chloroplast regulatory expression elements, flanked by two adjacent lettuce plastid genome sequences allowing its targeted insertion between the rbcL and accD genes. On average, we obtained 1 transplastomic lettuce plant per bombardment. We show that lettuce leaf chloroplasts can express transgene-encoded GFP to approximately 36% of the total soluble protein. All transplastomic T0 plants were fertile and the T1 progeny uniformly showed stability of the transgene in the chloroplast genome. This system will open up new possibilities for the efficient production of edible vaccines, pharmaceuticals, and antibodies in plants.

    This paper describes the ST/EL and ST/CV services for TI2 & TI8 LHC injection tunnels. The cooling and ventilation part describes the requirements for design and installation of more than 10 km of pipeline that is going to be laid down in the tunnels. Main operating parameters as well as manufacture procedures are explained. Preliminary work schedule with the cost estimate is also presented. Electrical power will be distributed from the LHC side and the SPS side for the machine and the general services. All power converters will be installed on surface buildings. The link between the main bend converters and the main bend magnets will be realised with water-cooled cables. Rest of the magnets will be cabled by using conventional copper and aluminium cables. Due to long lengths of the injection tunnels a dry 18kV transformer will be installed in TJ8 to serve the general services for TI8. The same will apply to TI2 by installing a transformer at the bottom of the PMI2 shaft.

    Full Text Available An Agrobacterium-mediated transformation method was applied to introduce the luciferase reporter gene under the control of the CaMV35S promoter in the pGreen0049 binary vector into strawberry cv. Camarosa. The in vitro regeneration system of strawberry leaves to be used in the transformation was optimized using different TDZ concentrations in MS medium. TDZ at 16 µM showed the highest percentage (100% of shoot formation and the highest mean number of shoots (24 produced per explant. Studies on the effects of different antibiotics, namely timentin, cefotaxime, carbenicillin and ampicillin, on shoot regeneration of strawberry leaf explants showed the best shoot regeneration in the presence of 300 mg/L timentin and 150 mg/L cefotaxime. Assessment of the different factors affecting Agrobacterium mediated-transformation of strawberry with the luciferase gene showed the highest efficiency of putative transformant production (86% in the treatment with no preculture, bacterial OD600 of 0.6 and the addition of 150 mg/L cefotaxime in the pre-selection and selection media. The presence of the luciferase gene in the plant genome was verified by the luciferase reporter gene assay, nested PCR amplification and dot blot of genomic DNA isolated from the young leaves of each putatively transformed plantlet.

    The entire flower of Tulipa gesneriana cv. Murasakizuisho is purple, except the bottom, which is blue. To elucidate the mechanism of the different color development in the same petal, we prepared protoplasts from the purple and blue epidermal regions and measured the flavonoid composition by HPLC, the vacuolar pH by a proton-selective microelectrode, and element contents by the inductively coupled plasma (ICP) method. Chemical analyses revealed that the anthocyanin and flavonol compositions in both purple and blue colored protoplasts were the same; delphinidin 3-O-rutinoside (1) and major three flavonol glycosides, manghaslin (2), rutin (3) and mauritianin (4). The vacuolar pH values of the purple and blue protoplasts were 5.5 and 5.6, respectively, without any significant difference. However, the Fe(3+) content in the blue protoplast was approximately 9.5 mM, which was 25 times higher than that in the purple protoplasts. We could reproduce the purple solution by mixing 1 with two equimolar concentrations of flavonol with lambda(vismax) = 539 nm, which was identical to that of the purple protoplasts. Furthermore, addition of Fe(3+) to the mixture of 1-4 gave the blue solution with lambda(vismax) = 615 nm identical to that of the blue protoplasts. We have established that Fe(3+) is essential for blue color development in the tulip.

    To understand the molecular mechanisms that control seed formation, we selected a seed-preferential gene (CvADH1) from the ESTs of developing watermelon seeds. RNA blot analysis and in situ localization showed that CvADH1 was preferentially expressed in the nucellar tissue. The CvADH1 protein shared about 50% homology with short-chain alcohol dehydrogenase including ABA2 in Arabidopsis thaliana, stem secoisolariciresinol dehydrogenase in Forsythia intermedia, and 3beta-hydroxysterol dehydrogenase in Digitalis lanata. We investigated gene-expression levels in seeds from both normally pollinated fruits and those made parthenocarpic via N-(2-chloro-4-pyridyl)-N'-phenylurea treatment, the latter of which lack zygotic tissues. Whereas the transcripts of CvADH1 rapidly started to accumulate from about the pre-heart stage in normal seeds, they were not detectable in the parthenocarpic seeds. Treating the parthenogenic fruit with GA(3) strongly induced gene expression, up to the level accumulated in pollinated seeds. These results suggest that the CvADH1 gene is induced in maternal tissues by signals made in the zygotic tissues, and that gibberellin might be one of those signals. We also observed that CvADH1 expression was induced by sucrose in the parthenocarpic seeds. Therefore, we propose that the CvADH1 gene is inducible by gibberellin, and that sucrose plays an important role in the maternal tissues of watermelon during early seed development.

    Vibroarthrography, a method for interpreting the sounds emitted by a knee during movement, has been studied for several joint disorders since 1902. However, to our knowledge, the usefulness of this method for management of Juvenile Idiopathic Arthritis (JIA) has not been investigated. To study joint sounds as a possible new biomarker for pediatric cases of JIA we designed and built VibroCV, a platform to capture vibroarthrograms from four accelerometers; electromyograms (EMG) and inertial measurements from four wireless EMG modules; and joint angles from two Sony Eye cameras and six light-emitting diodes with commercially-available off-the-shelf parts and computer vision via OpenCV. This article explains the design of this turn-key platform in detail, and provides a sample recording captured from a pediatric subject.

    2012-05-01

    Powdery mildew is a prevalent fungal disease affecting oat (Avena sativa L.) production in Europe. Common oat cultivar Rollo was previously shown to carry the powdery mildew resistance gene Eg-3 in common with cultivar Mostyn. The resistance gene was mapped with restriction fragment length polymorphism (RFLP) markers from Triticeae group-1 chromosomes using a population of F(3) lines from a cross between A. byzantina cv. Kanota and A. sativa cv. Rollo. This comparative mapping approach positioned Eg-3 between cDNA-RFLP marker loci cmwg706 and cmwg733. Since both marker loci were derived from the long arm of barley chromosome 1H, the subchromosomal location of Eg-3 was assumed to be on the long arm of oat chromosome 17. Amplified fragment length polymorphism (AFLP) marker technology featured as an efficient means for obtaining markers closely linked to Eg-3.

Nevertheless, the medical field is very wide, so for detecting diseases problems, not yet much disease that detection can be done with a computer-based system. One example of the issues is well-known disease detection, which is malaria. Malaria is classified as a serious disease because it can cause death if it is not treated properly. Malaria has various types and can affect anyone anywhere. The symptoms of malaria is really common as it may appear in daily life, but cannot always indicate that a person infected with malaria. Indications, which can show that a person infected with malaria, are the clinical examination and blood tests.With the blood test, the treatment of malaria can be implemented correctly and precisely. It needs technology that can detect malaria correctly and precisely. The solution is the method of support vector machine that can detect malaria in humans by viewing image of appearance blood cells.METHODThe methods used in this research are data collection, analysis and design. The data collection includes

    Full Text Available CV. X is still using a manual accounting system. They use a note for recording account receivable and account payable. Calculating total sales and profit do in manually. It takes a large amount of time to get some information that needed. Therefore an adequate accounting information system is needed in order to proceed an automate journalizing and to produce information accurately and quickly. First step in building accounting information system is to analyze and watch closely to the company's existing system. And the second step is to design the accounting information system, which can fulfill and appropriate with the company needs. The accounting information system is formed from integration of sales, purchasing and accounting/recording process. Including in sales are establishing sales order, checking available inventory for sale (stock and customer's credit limit. Including in purchasing is establishing purchase order until receiving and recording purchase invoice. Including in accounting/recording are journalizing, posting and reporting income statement. This software is using Microsoft SQL Server 7.0 as the database and Borland Delphi 7.0 as the compiler. Implementation for the whole software has gained 72.5% for user's satisfaction. Therefore it can be conclude that software has already fulfilled and appropriate with the needs of the company's system. But there also have some weakness to handle. This software helps in accelerating and simplifying the recording process and reporting income statement process. Abstract in Bahasa Indonesia : Sistem akuntansi pada CV.

  6. Health and economic impact of PHiD-CV in Canada and the UK: a Markov modelling exercise.

    2012-01-01

    The spectrum of diseases caused by Streptococcus pneumoniae and non-typeable Haemophilus influenzae (NTHi) represents a large burden on healthcare systems around the world. Meningitis, bacteraemia, community-acquired pneumonia (CAP), and acute otitis media (AOM) are vaccine-preventable infectious diseases that can have severe consequences. The health economic model presented here is intended to estimate the clinical and economic impact of vaccinating birth cohorts in Canada and the UK with the 10-valent, pneumococcal non-typeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV) compared with the newly licensed 13-valent pneumococcal conjugate vaccine (PCV-13). The model described herein is a Markov cohort model built to simulate the epidemiological burden of pneumococcal- and NTHi-related diseases within birth cohorts in the UK and Canada. Base-case assumptions include estimates of vaccine efficacy and NTHi infection rates that are based on published literature. The model predicts that the two vaccines will provide a broadly similar impact on all-cause invasive disease and CAP under base-case assumptions. However, PHiD-CV is expected to provide a substantially greater reduction in AOM compared with PCV-13, offering additional savings of Canadian $9.0 million and £4.9 million in discounted direct medical costs in Canada and the UK, respectively. The main limitations of the study are the difficulties in modelling indirect vaccine effects (herd effect and serotype replacement), the absence of PHiD-CV- and PCV-13-specific efficacy data and a lack of comprehensive NTHi surveillance data. Additional limitations relate to the fact that the transmission dynamics of pneumococcal serotypes have not been modelled, nor has antibiotic resistance been accounted for in this paper. This cost-effectiveness analysis suggests that, in Canada and the UK, PHiD-CV's potential to protect against NTHi infections could provide a greater impact on overall disease burden than

    The garden plant portulaca (Portulaca oleracea cv.) efficiently removes bisphenol A (BPA), an endocrine-disrupting chemical, from a hydroponic solution, but the molecular mechanisms underlying BPA metabolism by portulaca remain unclear. In this study, BPA metabolites converted by portulaca were analyzed by liquid chromatography coupled with tandem mass spectrometry. We observed the hydroxylation of BPA and the oxidization of it to quinone. Polyphenol oxidases are likely to contribute to BPA degradation by portulaca.

    Bunchy to virus (BTV) is the most destructive virus disease of banana in the Philippines. Incorporation of resistance to this virus disease by conventional hybridization is not possible due to male and female sterility of most commercial banana cultivars. In vitro culture coupled with radiation technology can be used to develop BTV resistance in banana cv. Lakatan. The sensitivity of banana shot tip explants to gamma irradiation was determined by subjecting the shoot tips to varying doses (5, 10, 20, 25, 30, 40, 60, 80 and 100 Gy) of irradiation. The LD sub 50 for banana shoot tips determined by 50% reduction in growth and shoot proliferation, was observed to around 20-25 Gy. Bulk irradiation of shoot tip explants was conducted using 20-25 Gy. Irradiated cultures were multiplied for 3-5 cycles and plants regenerated were potted out and screened for BTV resistance. A total of 3,447 irradiated plants regenerated from the radiosensitivity experiment (1,847 plants) and bulk irradiation of 20/25 Gy (1,600 plants) were screened for BTV resistance in the greenhouse using artificial BTV inoculation using the aphid vector Pentalonia nigronervosa. One hundred eighteen plants or 3.4% (118/3,447) of the artificially irradiated plants showed seedling resistance after 4-7 months of evaluation. These plants were planted in the field and were subjected to natural BTV infection. To date, 85 (out of the 118) putative seedling resistant plants continuously expressed BTV resistance in the field after more than 10 months of evaluation. The absence of BTV infection in 39 putative resistant plants was confirmed by ELISA test. Suckers from selected putative resistance plants will be collected, propagated and evaluated for the second cycle stability of BTV resistance and detailed characterization of important horticultural traits

Foram avaliadas as temperaturas -1,0 e -0,5ºC, e pressões parciais de CO2 de 0; 5 e 10kPa, com os tratamentos arranjados em um esquema bifatorial. Os frutos foram avaliados após 3 meses de armazenamento mais 3 dias de exposição à temperatura ambiente (18-20ºC. Conforme os resultados, não foi constatada interação entre os fatores, havendo efeito significativo para temperatura somente na firmeza de polpa, em que -1,0ºC apresentou frutos mais firmes. As diferentes pressões parciais de CO2 não influenciaram a perda de peso e a firmeza de polpa. As podridões apresentaram uma resposta linear negativa em relação ao CO2, porém, mantendo elevada ocorrência. Valores de CO2 entre 5 e 10kPa proporcionaram frutos com menor índice de escurecimento de epiderme e com coloração mais amarela e vermelha. O CO2 entre 5 e 10kPa apresentou os melhores resultados, que somados à temperatura de -1,0ºC, foi a melhor condição de armazenamento, que, no entanto, teve o período de conservação inferior a três meses nesta condição, devido às altas perdas por podridões.

    The rice cultivar ( Oryza sativa L.) BRS AG, developed by Embrapa Clima Temperado, is the first cultivar designed for purposes other than human consumption. It may be used in ethanol production and animal feed. Different abiotic stresses negatively affect plant growth. Soil salinity is responsible for a serious reduction in productivity. Therefore, the objective of this study was to evaluate the gene expression and the activity of antioxidant enzymes (SOD, CAT, APX and GR) and identify their functions in controlling ROS levels in rice plants, cultivar BRS AG, after a saline stress period. The plants were grown in vitro with two NaCl concentrations (0 and 136 mM), collected at 10, 15 and 20 days of cultivation. The results indicated that the activity of the enzymes evaluated promotes protection against oxidative stress. Although, there was an increase of reactive oxygen species, there was no increase in MDA levels. Regarding genes encoding isoforms of antioxidant enzymes, it was observed that OsSOD3 - CU/Zn , OsSOD2 - Cu/Zn , OsSOD - Cu/Zn , OsSOD4 - Cu/Zn , OsSODCc1 - Cu/Zn , OsSOD - Fe , OsAPX1 , OsCATB and OsGR2 were the most responsive. The increase in the transcription of all genes among evaluated isoforms, except for OsAPX6 , which remained stable, contributed to the increase or the maintenance of enzyme activity. Thus, it is possible to infer that the cv. BRS AG has defense mechanisms against salt stress.

    Full Text Available Growing plants in substrates is an alternative for the production of roses under unfavorable soil conditions. The objective of this study was to determine the biomass distribution efficiency of rose cv. Charlotte grown in soil and substrates under greenhouse conditions until second production peak. In this trial, soil and substrates with 100% burned rice husk (100BR H; 65% burned rice husk: 35% coconut fiber (65BR H; 35% burned rice husk: 65% coconut fiber (35BR H; and 100% coconut fiber (100CF were used. The experimental design consisted of a randomized complete block design with three repetitions. Destructive sampling was carried out using whole plants and flowering stems at previously determined bud stages. Leaf area and dry matter in organs were measured and growth rate and physiological indexes were calculated. The assessed variables were fitted to logistic and exponential models. The plants grown in substrates with BR H (burned rice husk showed similar values regarding dry matter and fresh weight accumulation in organs. Plants in the soil treatment were the last ones to reach the different development stages of the flowering buds, while those that were grown in 100CF were the first ones. The treatments 35BR H and 100CF showed less growth of flowering stems, which was expressed in terms of relative dry matter increase per day. The plants grown in soil showed more dry matter in leaves and stems but less in flower buds. The 65BR H treatment showed some of the highest dry matter accumulations in leaves, stems and flower buds and also showed the highest leaf area ratio, leaf weight ratio, and specific leaf area values

    The purified dioscorin from yam (Dioscorea alata L. cv. Tainong 1) tuber was previously reported (Hsu et al., 2002. J. Agric. Food Chem., 50, 6109-6113). In this report, we evaluated its immunomodulatory ability in vitro in the presence of polymyxin B (50 microg/ml) to eliminate lipopolysaccharide (LPS) contamination. Dioscorin (5-100 microg/ml) was able to stimulate nitric oxide production (expressed as nitrite concentrations) in RAW264.7 cells. The stimulation index on the phagocytosis of RAW264.7 cells against E. coli and the oxidative burst (determined by the intensity of rhodamine fluorescence) of RAW264.7 cells were both enhanced by different concentrations of dioscorin (5-100 microg/ml). The cytokine production, including IL-6, TNF-alpha, and IL-1beta in dioscorin-treated RAW264.7 cells or human monocytes, was measured in the cultured medium. Dioscorin (5-100 microg/ml) was found able to induce IL-6, TNF-alpha, and IL-1beta production in RAW264.7 cells and human monocytes. To evaluate the effects of dioscorin on the proliferation of spleen cells from BALB/c mice, phytohemagglutinin (PHA, 2 microg/ml) alone or PHA mixed with different concentrations of dioscorin (10, 25, and 50 microg/ml) was used to treat spleen cells for 24h. The stimulated proliferation index of splenic cells ranged from 1.38- to 1.48-fold of PHA alone for PHA mixed with different concentrations of dioscorin (10, 25, and 50 microg/ml). We suggest that the tuber storage protein of yam dioscorin functions as an immunomodulatory substance.

The soluble solids remained stable during this period, but there was decrease of pH and the levels of total and reducer sugars, in addition to increased acidity, facts that indicate occurrence of fermentation process. The losses of vitamin C were of the order of 72,5, from 4,952mg/100g in zero time, and 3,593mg/100g at the end of this period. The stored fruits at room temperature were discarded at the beginning of storage, by shriveling, incidence of microorganisms and strange odor.

    2014-01-01

    A mutation breeding program was initiated in 2008 emphasizing the main constraints for sustainable production of durum wheat in Saudi Arabia. The aim of the program was to develop moderate or high yielding semi-dwarf/lodging tolerant, early maturing mutants with drought and disease tolerance from a local durum wheat cultivar (Triticum durum Desf. cv. Samra) which has the main defects of longer crop duration, lodging habit and low grain yield. Dry seeds of Samra were subjected to 150 and 200Gy doses of gamma irradiation and each treatment consisted of 2500 seeds. Irradiated seeds were grown as M1 population along with parental variety as control at Almuzahmiah Research Station of Riyadh, Saudi Arabia. Decrease in germination (%) and survival rate (%) of plants was observed. A wide variation in days to flowering and plant height was found in the M1 populations. Three seeds from each spike per plant of M1 plants were collected, bulked dose wise and grown separately as M2 in 2009 growing season. From these M2, 17 desirable putative mutant plants which varied significantly with the mother were visually selected. These putative mutants were found to be semi-dwarf and early maturing in nature with other improved agronomic traits including lodging reaction and grain yield. The selected plants, when grown in progeny lines as M3 in 2010, more or less maintained their superiority over the mother for many traits. Most of the mutant lines showed homogeneity for most of characters studied. Eleven of these 17 lines were found to be promising in respect of days to flower, plant height (for semi-dwarf) and other traits including grain yield. (author)

    In this work, apples of cv. Golden Delicious were cut into slices that were 5 and 7 mm thick and then vacuum dried at 50, 60 and 70 °C and pressure of 0.02 bar. The thin layer model drying kinetics was studied, and mass transfer properties, specifically effective moisture diffusivity and convective mass transfer coefficient, were evaluated using the Fick's equation of diffusion. Also, thermodynamic parameters of the process, i.e. enthalpy (ΔH), entropy (ΔS) and Gibbs free energy (ΔG), were determined. Colour properties were evaluated as one of the important indicators of food quality and marketability. Determination of mass transfer parameters and thermodynamic properties of vacuum dried apple slices has not been discussed much in the literature. In conclusion, the Nadi's model fitted best the observed data that represent the drying process. Thermodynamic properties were determined based on the dependence of the drying constant of the Henderson and Pabis model on temperature, and it was concluded that the variation in drying kinetics depends on the energy contribution of the surrounding environment. The enthalpy and entropy diminished, while the Gibbs free energy increased with the increase of the temperature of drying; therefore, it was possible to verify that variation in the diffusion process in the apple during drying depends on energetic contributions of the environment. The obtained results showed that diffusivity increased for 69%, while the mass transfer coefficient increase was even higher, 75%, at the variation of temperature of 20 °C. The increase in the dimensionless Biot number was 20%.

    Brazil is one of the largest mango producers and the third largest mango exporter worldwide. Irradiation treatment and its commercial feasibility have been studied in our country to make it possible to develop new markets and, consequently, to compete with the major exporters of mangoes, Mexico and India. This work was designed to compare irradiation treatment with the hot water dip treatment in mangoes cv. Tommy Atkins for export and to verify that the main attributes for acceptance, color and texture, as well as carbohydrate and organic acid contents, were maintained. In this study, the fruit was divided into groups: control, hot water dip-treated (46 °C for 90 min), and irradiation-treated at doses of 0.4 kGy and 1.0 kGy. The fruit was stored at low temperature (11 °C±2) for 14 days and then at room temperature (23 °C±2) until the end of the study. The results indicated that the fruit given a dose of 1.0 kGy remained in a less advanced stage of ripening (stage 3) throughout the storage period, but experienced a greater loss of texture in the beginning of the experiment. It was noted that only the control group had higher levels of citric acid and succinic acid on the last day of the experiment. There were no significant differences in the total sugar content between any treatment groups. Gamma radiation can be used as a quarantine treatment and does not interfere negatively with the quality attributes of mangoes.

    Analyzing the alteration in an olivine chondrule of the NWA 2086 CV3 meteorite, infrared spectral, electron microprobe and optical microscopic observations were correlated to each other. The intensity and wavelength positions of olivine peaks changed characteristically with the progression of alteration and related Fe/Mg substitution inward of the chondrule. Moderate to good correlations were identified between Fo% composition and positions of 830 and 860 cm-1 IR peaks. The disappearance of 1020 cm-1 peak by structural change happens already at a low level alteration without changing the optical appearance of the mineral. The existence of the 980 cm-1 peak is found to be an indicator of the intact phase of olivine. While profiles perpendicular to the chondrule's perimeter showed that the alteration progressed 15-20 μm distance inward without observable fractures (probablly by some diffusion related process), the "alteration distance" from various obvious fractures inside the chondrule was only 3-5 μm distance. These observations suggest that the substitution was more effective close to the matrix, and also related to some fluids that although were able to circulate along the large internal fractures too, did not produce such strong substitution there, like what happened close to the matrix. It was also demonstrated that the poorly exploited contact mode observations with ATR based reflection method in infrared spectroscopy provide a useful tool to analyze the alteration at micrometer scale without much sample preparation, and enable identifying alterations already at such a low level where the olivines still look optically intact.

    Full Text Available Emotions represent feelings about people in several situations. Various machine learning algorithms have been developed for emotion detection in a multimedia element, such as an image or a video. These techniques can be measured by comparing their accuracy with a given dataset in order to determine which algorithm can be selected among others. This paper deals with the comparison of two implementations of emotion recognition in faces, each implemented with specific technology. OpenCV is an open-source library of functions and packages mostly used for computer-vision analysis and applications. Cognitive services is a set of APIs containing artificial intelligence algorithms for computer-vision, speech, knowledge, and language processing. Two Android mobile applications were developed in order to test the performance between an OpenCV algorithm for emotion recognition and an implementation of Emotion cognitive service. For this research, one thousand tests were carried out per experiment. Our findings show that the OpenCV implementation got a better performance than the Cognitive services application.

    JWST Integrated Science Instruments Module (ISIM) has completed its system-level testing program at the NASA Goddard Space Flight Center (GSFC). In March 2016, ISIM was successfully delivered for integration with the Optical Telescope Element (OTE) after the successful verification of the system through a series of three cryo-vacuum (CV) tests. The first test served as a risk reduction test; the second test provided the initial verification of the fully-integrated flight instruments; and the third test verified the system in its final flight configuration. The complexity of the mission has generated challenging requirements that demand highly reliable system performance and capabilities from the Space Environment Simulator (SES) vacuum chamber. As JWST progressed through its CV testing campaign, deficiencies in the test configuration and support equipment were uncovered from one test to the next. Subsequent upgrades and modifications were implemented to improve the facility support capabilities required to achieve test requirements. This paper: (1) provides an overview of the integrated mechanical and thermal facility systems required to achieve the objectives of JWST ISIM testing, (2) compares the overall facility performance and instrumentation results from the three ISIM CV tests, and (3) summarizes lessons learned from the ISIM testing campaign.

    Full Text Available Micro-morphological changes precede the appearance of visible damage after herbicide application and are essential in providing data for the safe recommendation in chemical management of weeds. Therefore, the aim of this research was to verify the anatomical changes of leaf tissue caused by application of herbicides in cassava (Manihot esculenta Crantz. cv. IAC-12. A greenhouse experiment was conducted with post-emergence herbicides treatments as follows: nicossulfuron (60 g a.i ha-1, fluazifop (250 g a.i ha-1, fomesafem (250 g a.i ha-1, metribuzin (480 g a.i ha-1, oxyfluorfen (720 g a.i ha-1 and the mixture fluazifop + fomesafen (200 + 250 g a.i ha-1, and an untreated control, respectively. The results obtained have allowed to affirm the cassava plants (cultivar IAC-12, exhibited changes in leaf anatomy in response to herbicide application even on cassava leaves without no visual toxicity symptoms. The products caused alterations both in tissue thickness as in tissue proportion in the leaf blade. For the fluazifop, a eudicotyledonous selective herbicide, changes were observed in tissue thickness and proportion of leaf blade, even without any visual toxicity detected. Cassava plants (IAC-12, showed structural changes in leaf anatomy in response to application of herbicides. The leaf anatomy of cassava cv. IAC-12, can be used to indicate the herbicide effect on cassava (Manihot esculenta Crantz.cv. IAC-12 plants.

  7. Solution NMR Structure of Hypothetical Protein CV_2116 Encoded by a Viral Prophage Element in Chromobacterium violaceum

    Full Text Available CV_2116 is a small hypothetical protein of 82 amino acids from the Gram-negative coccobacillus Chromobacterium violaceum. A PSI-BLAST search using the CV_2116 sequence as a query identified only one hit (E = 2e−07 corresponding to a hypothetical protein OR16_04617 from Cupriavidus basilensis OR16, which failed to provide insight into the function of CV_2116. The CV_2116 gene was cloned into the p15TvLic expression plasmid, transformed into E. coli, and 13C- and 15N-labeled NMR samples of CV_2116 were overexpressed in E. coli and purified for structure determination using NMR spectroscopy. The resulting high-quality solution NMR structure of CV_2116 revealed a novel α + β fold containing two anti-parallel β -sheets in the N-terminal two-thirds of the protein and one α-helix in the C-terminal third of the protein. CV_2116 does not belong to any known protein sequence family and a Dali search indicated that no similar structures exist in the protein data bank. Although no function of CV_2116 could be derived from either sequence or structural similarity searches, the neighboring genes of CV_2116 encode various proteins annotated as similar to bacteriophage tail assembly proteins. Interestingly, C. violaceum exhibits an extensive network of bacteriophage tail-like structures that likely result from lateral gene transfer by incorporation of viral DNA into its genome (prophages due to bacteriophage infection. Indeed, C. violaceum has been shown to contain four prophage elements and CV_2116 resides in the fourth of these elements. Analysis of the putative operon in which CV_2116 resides indicates that CV_2116 might be a component of the bacteriophage tail-like assembly that occurs in C. violaceum.

  8. Melanie Klein in Buenos Aires: beginnings and developments.

    2005-06-01

    In the first decades of the 20th century, Freud was known and quoted in Latin America by an elite of enlightened minds. In the 1940s a convergence took place in Buenos Aires of European exiles with local pioneers, and thus the Argentine Psychoanalytical Association was founded in 1942. Since then psychoanalysis has grown steadily and has spread into hospitals and universities, influencing culture at large. The socioeconomic situation of that time permitted this phenomenon to develop, to the astonishment of observers. In this paper the authors study the strong influence of Kleinian thought during the first 30 years of this development. The original works of local thinkers constitute the intellectual capital that sustains the idea of an 'Argentine psychoanalytic school'. During the 1970s, both society and psychoanalysis endured deep and complex changes. Lacan's teachings gained support and Klein's influence began to decline. At present the Buenos Aires Kleinians keep working, while their relationship with Lacanians and other schools is calmer. Respectful discussions became thus possible, oriented to strictly scientific differences.

    The discussion comments firstly on the role of synchronicity which seems so natural and significant for Jungians but which Freudians would think no more than interesting coincidences. This gives an idea of how different the two schools' approach to the psyche can be. Some theoretical elaboration is made regarding archetypes and primal phantasies: primal phantasies are much related to sexuality, but sexuality understood as intimately linked to the great mysteries of life. The discussion of the clinical work shows more similarities than differences. This suggests that for both perspectives the clinical is sovereign. As we know, respect and care for the patient's evolution, true concern for the patient and skilful use of technique remain the most important indicators of successful therapeutic work in the different psychotherapeutic approaches. © 2011, The Society of Analytical Psychology.

    Context: Although epidemiological studies have found that GH and IGF-1 normalization reduce the excess mortality of active acromegaly to expected rates, cross-sectional data report some cardiovascular (CV) risk markers to be less favorable in remission than active acromegaly. Objective: The objective of the study was to test the hypothesis that remission of acromegaly after surgical therapy increases weight and adiposity and some CV risk markers and these changes are paralleled by a rise in ghrelin. Design: Forty-two adults with untreated, active acromegaly were studied prospectively. Changes in outcome measures from before to after surgery were assessed in 26 subjects achieving remission (normal IGF-1) and 16 with persistent active acromegaly (elevated IGF-1) after surgery. Setting: The study was conducted at tertiary referral centers for pituitary tumors. Main Outcome Measures: Endocrine, metabolic, and CV risk parameters, anthropometrics, and body composition by dual-energy X-ray absorptiometry were measured. Results: Remission increased total ghrelin, body weight, waist circumference, C-reactive protein, homocysteine, high-density lipoprotein, and leptin and reduced systolic blood pressure, homeostasis model assessment score, triglycerides, and lipoprotein (a) by 6 months and for 32 ± 4 months after surgery. The ghrelin rise correlated with the fall in the levels of GH, IGF-1, and insulin and insulin resistance. Weight, waist circumference, and ghrelin did not increase significantly in the persistent active acromegaly group. Total body fat, trunk fat, and perentage total body fat increased by 1 year after surgery in 15 remission subjects: the increase in body fat correlated with the rise in total ghrelin. Conclusions: Although most markers of CV risk improve with acromegaly remission after surgery, some markers and adiposity increase and are paralleled by a rise in total ghrelin, suggesting that these changes may be related.

    Full Text Available The use of the associacion of grasses and legumes results in a good forage yield as well as a good animal performance due to maintenance of adequate levels of crude protein (CP in the animal diet, both the direct effect of the ingestion of legumes, or even through indirect effect of the introduction of nitrogen by legumes in the pasture, thereby increasing the production of forage mass. However, the seeds of legumines have the so-called hardness seeds or dormant according to their coats impermeable to water. The hardness of the seed prevents the germination of the same since these seeds have a hard shell impervious to water and gas exchange, not allowing the imbibition of water by the seed, or embryo oxygenation. This dormancy may be broken by various known methods such as scarification, promoting cracks in the seed coat allowing the entry of water therein. In the case of Macrotyloma axillare exposure of seeds to scarification method has proven to be an efficient way to break dormancy and promoting seed germination. The aim of the present work was to evaluate the viability of seeds after suffering dormancy by immersion seeds in sulfuric acid. The experiment to break dormancy Macrotyloma axillares cv. Guatá was conducted in the laboratory of Plant Physiology at the Intituto de Zootecnia in Nova Odessa, São Paulo State, using the seeds that were stored in a cold room with temperatures between 10-12 ºC, relative humidity (RH 30-33% and no light. The treatments studied were: control, chemical scarification with sulfuric acid for 5, 10, 15, 20, 30 and 40 minutes. We used a completely randomized design with two replications, being 100 seeds each repetition. After treatment the seeds were under to tetrazolium test resulting in viable seeds and seed viability. So the result of the tetrazolium test was obtained by average percentage of viable seeds, found in the repeats tested, respecting the maximum tolerances set out in Brazilian Rules for Seed

    Brazil is one of the largest mango producers and the third largest mango exporter worldwide. Irradiation treatment and its commercial feasibility have been studied in our country to make it possible to develop new markets and, consequently, to compete with the major exporters of mangoes, Mexico and India. This work was designed to compare irradiation treatment with the hot water dip treatment in mangoes cv. Tommy Atkins for export and to verify that the main attributes for acceptance, color and texture, as well as carbohydrate and organic acid contents, were maintained. In this study, the fruit was divided into groups: control, hot water dip-treated (46 °C for 90 min), and irradiation-treated at doses of 0.4 kGy and 1.0 kGy. The fruit was stored at low temperature (11 °C±2) for 14 days and then at room temperature (23 °C±2) until the end of the study. The results indicated that the fruit given a dose of 1.0 kGy remained in a less advanced stage of ripening (stage 3) throughout the storage period, but experienced a greater loss of texture in the beginning of the experiment. It was noted that only the control group had higher levels of citric acid and succinic acid on the last day of the experiment. There were no significant differences in the total sugar content between any treatment groups. Gamma radiation can be used as a quarantine treatment and does not interfere negatively with the quality attributes of mangoes. - Highlights: ► In Brazil, one of the largest producers and exporters of mangoes, tropical fruits are routinely treated with a hot water dip. ► Results from this study demonstrate that irradiation is a good alternative to this conventional quarantine treatment. ► Carbohydrate and organic acid results are presented for irradiation and hot water dip treatments. ► Texture measurements are shown as a function of storage time for each of these treatments.

    Recurrent outbreaks of sudden death and bloody diarrhea were reported in March 2013 and February 2014 in a breeding colony of Papillon dogs. During the first outbreak, 1 adult dog and 2 eight-month-old puppies died. During the second outbreak, 2 ten-week-old puppies died. One puppy from the first outbreak and 2 puppies from the second outbreak were examined at necropsy. Histologically, all 3 puppies had severe segmental crypt necrosis of the small intestine and marked lymphoid follicle depletion in the spleen and Peyer's patches. Real-time (RT) polymerase chain reaction (PCR) demonstrated abundant canine parvovirus (CPV-2) DNA (Ctcanine circovirus 1 (CaCV-1). Very high levels of CaCV-1 DNA (Ct<13) were detected in small intestine, lymph nodes, and spleen. In situ hybridization for CaCV-1 detected rare positive nuclei of regenerating crypt epithelium but abundant amounts of CaCV-1 nucleic acid in the cytoplasm and nuclei of histiocytes in all lymphoid tissues, including granulomatous inflammatory foci and hepatic Kupffer cells. Significant levels of CaCV-1 DNA were detected in blood and serum (Ct as low as 13) but not feces from 3 surviving dogs at 2 months or 1 year after the outbreak, respectively. We hypothesize that CPV-2 infection predisposed dogs to CaCV-1 infection and ultimately resulted in more severe clinical disease. © The Author(s) 2016.

    A dichotic CV-syllable listening task was administered to a group of eleven non-brain-injured adults and to a group of eleven adult aphasics. The results of this study may be summarized as follows: 1)The group of non-brain-injured adults showed a slight right ear advantage for dichotically presented CV-syllables. 2)In comparison with the control group the asphasic group showed a bilateral deficit in response to the dichotic CV-syllables, superimposed on a non-significant right ear advantage. 3) The asphasic group demonstrated a great deal of intersubject variability on the dichotic task with six aphasics showing a right ear preference for the stimuli. The non-brain-injured subjects performed more homogeneously on the task. 4) The two subgroups of aphasics, a right ear advantage group and a left ear advantage group, performed significantly different on the dichotic listening task. 5) Single correct data analysis proved valuable by deleting accuracy of report for an examination of trials in which there was true competition for the single left hemispheric speech processor. These results were analyzed in terms of a functional model of auditory processing. In view of this model, the bilateral deficit in dichotic performance of the asphasic group was accounted for by the presence of a lesion within the dominant left hemisphere, where the speech signals from both ears converge for final processing. The right ear advantage shown by one asphasic subgroup was explained by a lesion interfering with the corpus callosal pathways from the left hemisphere; the left ear advantage observed within the other subgroup was explained by a lesion in the area of the auditory processor of the left hemisphere.

    The effect of partial defoliation of Vitis vinifera L. cv Cabernet Sauvignon on the distribution of photosynthetates, originating in leaves in different positions on the shoot at berry set, pea size, veraison and ripeness stages, was investigated. Partial defoliation (33% and 66%) resulted in a higher apparent photosynthetic effectivity for all the remaining leaves on the shoot. The pattern of distribution of photosynthetates would seem to stay the same between the defoliation treatments. The control vines were found to carry excess foliage. Optimal photosynthetic activity of all the leaves on the vine was therefore not reached

The micro-hardness increased with the progress of degradation and related well with decrease of ultimate elongation of the sheath material, and was also reflected by the loss of plasticizer. The micro-hardness technique has a possibility to detect the degradation of cable as a non-destructive detector. (author)

  8. Ozone effects on radish (Raphanus sativus L. cv. Cherry Belle): foliar sensitivity as related to metabolite levels and cell architecture

    The development of the first four leaves of radish (Raphanus sativus L. cv. Cherry Belle) was followed to determine the relationship between foliar sensitivity to ozone as related to selected soluble metabolites and leaf-cell arrangement. Although relatively high metabolite (protein, sugars, phenols) levels and compact cell arrangement may be advanced as factors contributing to the resistance of young leaves (L/sub 3,4/ of 21-day old plants) these same parameters do not explain the resistance of old leaves (L/sub 1,2/ of 30-day old plants). 16 references, 4 figures, 1 table.

    Full Text Available This study aimed to evaluate the postharvest behavior of peach cv. Aurora 1 harvested in the Zona da Mata region of Minas Gerais in two ripening stages and kept under different storage temperatures. Fruits on mid-ripe and fully ripe stages were stored at three temperatures: 5.6 ± 1.57 °C and 72.8 ± 3.8% RH; 10.4 ± 0.5 °C and 95.8 ± 5.5% RH; 21.04 ± 1.63 °C and 96.9 ± 2.6% RH up to 28 storage days (SD . During storage, fruits stored at 21.04 ± 1.63 °C were evaluated every two days until 8 SD, and every four days for fruits stored at other temperatures. The harvest day was assigned as day zero. The variables evaluated were CO2 production, color of the pericarp and pulp, fresh mass loss, flesh firmness, total soluble solids, titratable acidity, contents of ascorbic acid and carotenoids. The fresh mass loss increased during storage, peaking at 5.6 °C. The reduction in ascorbic acid content was higher in fully ripe fruits at all temperatures. Mid-ripe fruits reached the end of the storage period with better quality. The temperature of 10.4 °C was the most efficient in keeping postharvest quality of peach cv. Aurora 1 harvested in the Zona da Mata region.

    The Rio Grande reservoir is located in the Metropolitan area of Sao Paulo and it is used for recreation purposes and as source water for drinking water production. During the last decades has been detected mercury contamination in the sediments of this reservoir, mainly in the eastern part, near the main affluent of the reservoir, in the Rio Grande da Serra and Ribeirao Pires counties. In the present study bottom sediment samples were collected in four different sites into four sampling campaigns during the period of September 2008 to January 2010. The samples were dried at room temperature, ground and passed through a 2 mm sieve. Total Hg determination in the sediment samples was carried out by two different analytical techniques: neutron activation analysis (NAA) and cold vapor atomic absorption spectrometry (CV AAS). The methodology validation, in terms of precision and accuracy, was performed by reference materials, and presented a recovery of 83 to 108%. The total Hg results obtained by both analytical techniques ranged from 3 to 71 mg kg-1 and were considered similar by statistical analysis, even though NAA technique furnishes the total concentration while CV AAS using the 3015 digestion procedure characterizes only the bioavailable Hg. These results confirm that both analytical techniques were suitable to detect the Hg concentration levels in the Rio Grande sediments studied. The Hg levels in the sediment of the Rio Grande reservoir confirm the anthropogenic origin for this element in this ecosystem. (author)

    Seed oil and flours have been attracting the interest of researchers and industry, since they contain various bioactive components. We monitored the effects of ripening on lipids, monomeric flavan-3-ols, proanthocyanidins and tocols concentration in seed extracts from organically cultivated cv. Sangiovese vines. Linoleic acid was the most abundant fatty acid, followed by oleic, palmitic and stearic acids. The tocols detected were α-tocopherol, α-tocotrienol and γ-tocotrienol. The proanthocyanidins degree of polymerisation ranged from dimers to dodecamers; moreover, monomeric flavan-3-ols and polymeric proanthocyanidins were detected. Total flavan-3-ols (monomers, oligomers and polymers) concentration in grape seeds decreased during ripening. Fatty acids reached the highest level in post-veraison. The concentration of these compounds varied considerably during ripening. Capric acid has been found for the first time in grape seeds. α-Tocopherol and γ-tocotrienol decreased during ripening, while α-tocotrienol increased. The HPLC analysis with fluorimetric detection, conducted for the first time on cv. Sangiovese, revealed that the concentration of flavan-3-ols monomers, oligomeric proanthocyanidins and polymers greatly changed during ripening. These results suggest that the timing of bunch harvest plays a crucial role in the valorisation of grape seed flour. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    Full Text Available The effect of water stress on germination of radish seeds is dependent on the presence of light. The effect of pelletization of radish seeds with powdered graphite on the tolerance to water stress under light was analysed. White light and far-red lights were filtered by graphite increasing slightly the tolerance of pelleted seeds to water stress of -0.77MPa. Although red light also inhibited seed germination the graphite had no effect. We propose the pelletization of seeds of Raphanus sativus, at least in cv redondo gigante with graphite as a pratice before planting to increase the tolerance to water stress.O efeito do estresse hídrico é dependente da presença de luz em sementes de rabanete. O efeito da peletização com grafite em pó foi analisado.

Embora a luz vermelha também iniba a germinação em condições de estresse a peletização não teve efeito. Nós propomos a peletização de sementes de Raphanus saivus L. cv. redondo gigante como uma prática antes do plantio para aumentar a tolerância ao estresse hídrico.

  17. Processor core for real time background identification of HD video based on OpenCV Gaussian mixture model algorithm

    Genovese, Mariangela; Napoli, Ettore

    2013-05-01

    The identification of moving objects is a fundamental step in computer vision processing chains. The development of low cost and lightweight smart cameras steadily increases the request of efficient and high performance circuits able to process high definition video in real time. The paper proposes two processor cores aimed to perform the real time background identification on High Definition (HD, 1920 1080 pixel) video streams. The implemented algorithm is the OpenCV version of the Gaussian Mixture Model (GMM), an high performance probabilistic algorithm for the segmentation of the background that is however computationally intensive and impossible to implement on general purpose CPU with the constraint of real time processing. In the proposed paper, the equations of the OpenCV GMM algorithm are optimized in such a way that a lightweight and low power implementation of the algorithm is obtained. The reported performances are also the result of the use of state of the art truncated binary multipliers and ROM compression techniques for the implementation of the non-linear functions. The first circuit has commercial FPGA devices as a target and provides speed and logic resource occupation that overcome previously proposed implementations. The second circuit is oriented to an ASIC (UMC-90nm) standard cell implementation. Both implementations are able to process more than 60 frames per second in 1080p format, a frame rate compatible with HD television.

    At the start of work by M3 Wave under the current DOE funding, the DMP technology was nominally at TRL2 with some physical model testing completed. With DOE and OWET funding, much progress was made on several fronts including: cost of energy modeling, 1:50 scale model testing, numerical modeling, site evaluation, cost of mooring, construction, operations and maintenance, regulatory, and power take off. Since the technology is stationary on the ocean floor, arrays can be very dense. Even though overall efficiency is lower than buoys, the total power per acre of the technology looks to be at least twice the output per acre of known buoy WEC technologies. If the assumptions and inputs are correct, then DMP ocean power devices could be commercially competitive with other offshore renewable energy resources, such as off-shore wind power. Leveraging the data, analysis, and engineering conducted on this project, larger 1:6 scale testing was recently completed under separate funding. All aspects tested at 1:6 suggest that the DMP is a viable and disruptive technology, leading M3 Wave to continue development of the DMP.

    Full Text Available Based on a C8051F006 SoC (system on-a-chip, a simple and low cost quasi-static capacitance-voltage (C-V meter was designed and developed to obtain C-V characteristics of semiconductor devices. The developed C-V meter consists of a capacitance meter, a programmable voltage source, a C8051F006 SoC-based slave controller, and a personal computer (PC as a master controller. The communication between the master and slave controllers is facilitated by the RS 232 serial communication. The accuracy of the C-V meter was guaranteed by the calibration functions, which are employed by the program in the PC and obtained through the calibration processes of analog to digital converter (ADC, digital to analog converters (DACs of the C8051F006 SoC, and the programmable voltage source. Examining 33-pF and 1000-pF capacitors as well three different p-n junction diodes, it was found that the capacitances of common capacitors are in the range of specified values and typical C-V curves of p-n junction diodes are achieved.

    Diabetes mellitus is a major global health problem. Needling at CV-12 has reduced blood glucose level in diabetic rats. The aim of this study was to evaluate the effect of needling at CV-12 (Zhongwan) on blood glucose level in patients with type 2 diabetes mellitus (T2DM). Forty T2DM patients were recruited and randomized into either the acupuncture group or placebo control group. The participants in the acupuncture group were needled at CV-12 (4 cun above the center of the umbilicus), and those in the placebo control group were needled at a placebo point on the right side of the abdomen (1 cun beside the CV-12). For both groups, the needle was retained for 30 minutes. Assessments were performed prior to and after the intervention. Statistical analysis was performed using SPSS version 16. There was a significant reduction in random blood glucose level in the acupuncture group compared to baseline. No such significant change was observed in the placebo control group. The result of this study suggests that 30 minutes of needling at CV-12 might be useful in reducing blood glucose level in patients with T2DM. Copyright © 2017. Published by Elsevier B.V.

    Full Text Available The occurrence of somaclonal variation is described in various cultures of agronomic interest. Such variation can be of benefit in the development of new flower varieties. In this study, the occurrence of somaclonal variation in micropropagated changes of Heliconia bihai cv. Lobster Claw I was investigated. Stem apexes were introduced in MS culture media with the addition of 2.5 mg L-1 of benzylaminopure (BAP and 500 mg L-1 of sodium cefotaxime. After selecting the apex stem, it was sub-cultivated in MS media and supplemented with 4.0 mg L-1 of BAP to induce side buds. To conduct the trial, 2,000 plants were selected and compared with plants originated from rhizomes. To calculate the percentage of the variants, the plant stature, the form and color of leaves and pseudostem were evaluated. The plants with buds presenting the same type of variation were considered as variants. The occurrence of three types of somaclonal variants was observed: Variation of the Chlorophyll in the Leaf, Low Stature Variant and Pseudostem and Petiole Color Variant, the latter with ornamental potential. The somaclonal variation rate for Heliconia bihai cv Lobster Claw I, under the proposed conditions, was 61.40%.A ocorrência de variação somaclonal é descrita em diversas culturas de interesse agronômico.

    Full Text Available The avocado tree (Persea americana Mill. is one of the species most sensitive to salinity. Since the root system of this species is particularly affected by this type of stress, it is crucial to find a rootstock that is tolerant to saline water irrigation. Plant material from the cv. Hass was grafted on five rootstocks to find possible candidates: the clonal ‘Duke 7’, ‘Nabal’, ‘Degania 117’,’Mexicola’, and ‘Zutano’ seedlings. One year-old plants were placed in 55 L pots; river sand was used as substrate, and the plants were fertilized with a modified Hoagland solution. Vegetative growth and internal nutrient content were compared with control plants with 30 mg L-1 of Cl-, and plants treated with 200 mg L-1 Cl- for 130 days using NaCl in the nutrient solution (5.64 mM. No interaction between NaCl and the rootstocks for the vegetative growth variables was detected neither in K+ internal foliar or root content nor Ca+2 root. With regard to the carbon assimilation rate, the Nabal rootstock showed the highest rates under the NaCl treatment by retaining the highest chloride concentration in the roots and greatly limiting the concentration found in the leaves of the cv. Hass cultivar. It is therefore a promising rootstock for salt tolerance.El palto (Persea americana Mill. es una de las especies más sensibles a la salinidad, debido a que su sistema radical es particularmente afectado por este estrés, es importante identificar un portainjerto tolerante al riego con agua salina. Para encontrar posibles candidatos se utilizó material vegetal del cv. Hass injertado sobre cinco portainjertos, el clonal Duke 7 y los provenientes de semilla, Nabal, Degania 117, Mexícola y Zutano. Plantas de 1 año de edad fueron colocadas en macetas de 55 L, con arena de río como sustrato y fertilizadas con una solución Hoagland modificada. Durante 130 días se comparó el crecimiento vegetativo y los contenidos internos de nutrientes en plantas

    Full Text Available The role of the seed coat in the light sensitivity of seeds of Raphanus sativus L. cv. redondo gigante was analysed by germination tests of intact and naked seeds. Far-red light caused high inhibition of seed germination, while under white and red lights low inhibition was found. Naked seeds presented no light sensitivity with high percentage germination under light and darkness. However, incubation of naked seeds in -0.6MPa polyethylene glycol solution resulted in light inhibition as observed in intact seeds. The analysis of the seed coat transmitted light indicated that the filtered light presented the same photoequilibrium of phytochrome when compared to the white light, with a decrease of only 33% in the light irradiance which reaches the embryo.O papel do tegumento sobre a sensibilidade à luz em sementes de Raphanus sativus L. cv. redondo gigante foi analisado por testes de germinação de sementes intactas e nuas. A luz vermelho-extremo inibiu fortemente a germinação, enquanto as luzes branca e vermelha apresentaram baixa inibição. Por outro lado, sementes nuas não apresentaram sensibilidade à luz, com alta porcentagem de germinação tanto na luz como no escuro. Entretanto, a incubação das sementes nuas em condições de estresse em solução de polietilenoglicol a -0,6MPa, resultou em inibição na luz, como observadas em sementes intactas. A análise da luz transmitida pelo tegumento das sementes indicou que a luz filtrada apresenta o mesmo fotoequilíbrio teórico do fitocromo obtido na luz branca, com um decréscimo em apenas 33% da irradiância que atinge o embrião.

    Porcine epidemic diarrhoea virus, strain CV777, was initially characterized in 1978 as the causative agent of a disease first identified in the UK in 1971. This coronavirus has been widely distributed among laboratories and has been passaged both within pigs and in cell culture. To determine...... the variability between different stocks of the PEDV strain CV777, sequencing of the full-length genome (ca. 28kb) has been performed in 6 different laboratories, using different protocols. Not surprisingly, each of the different full genome sequences were distinct from each other and from the reference sequence...... the analysis of sub-genomic mRNAs from infected cells. It is clearly important to know the features of the specific sample of CV777 being used for experimental studies....

  17. C-V and G-V characteristics of ion-implanted MOS structures depending upon the geometrical structure of the implanted region

    Zohta, Y.

    1977-01-01

    It is found that the capacitance-voltage (C-V) and conductance-voltage (G-V) characteristics of MOS capacitors, into which ions of the opposite conductivity type are implanted, depend strongly upon the geometrical structure of the ion-implanted region. This phenomenon can be analyzed in terms of lateral current flow which connects an inversion layer formed in the ion-implanted region to a surrounding nonimplanted substrate. On the basis of this model, the C-V and G-V characteristics are calculated using a simple equivalent circuit, and general relationships inherent in this model are obtained. MOS capacitors with an ion-implanted layer of different geometries have been prepared to measure their C-V and G-V characteristics. Comparison of experimental measurements with theory substantiates the lateral current flow model

    Full Text Available ‘Broma’ is a grass cultivar belonging to the species Bromus carinatus. In the Lists of Agricultural Plant Varieties of the Research Centre for Cultivar Testing (COBORU, it is shown as Bromus willdenowii (= B. catharticus, B. unioloides (List of Agricultural Plant Varieties 1989-2009, whereas already in 1984 Mirek demonstrated on the basis of morphological analysis that this was a different closely related species – B. carinatus. The aim of the present study was to verify the species affiliation of cv. ‘Broma’. The conducted analysis of ISSR molecular markers included representatives of cv. ‘Broma” as well as of B. carinatus and B. willdenowii. The method used allowed the identification of molecular markers of the above-mentioned taxa. The numerical analysis of the obtained results suggests that cv. ‘Broma’ should be classified in the species B. carinatus, not B. willdenowii.

  19. Using the C-V curve of an mis diode to examine the trapping levels in a semiconductor containing many discrete traps

    It is shown that the trap concentrations and depths can be obtained from the slopes of the ( C/ ci) 2 vs VG curves and the change in ( C/ Ci) 2 at the transition points for an MIS diode, and that this method is particularly applicable to single type semiconductors such as CdS. This is done by developing equations using the abrupt depletion layer model. In this paper the equations are derived, they are used to determine the ideal C-V curves of copper doped CdS, and then they are used to analyze C-V curves of gold doped silicon. Equations are also derived that predict how the C-V curve will be affected when the depletion layer punches through a doped layer, and calculations are made for copper doped CdS.

    The C-V characteristics of the structure M-TmF 3 -SiO 2 -Si, thermally treated at a temperature of 300 0 C for 15 minutes, were investigated. At higher temperatures to about 150 0 C, the hysteresis of the C-V characteristics is completely absent, whereas at room temperature hysteresis depends on the applied voltage and on the material of the gate electrode. The dependence of the flat band voltage shift on the applied voltage, the thickness of SiO 2 layer and the material of the gate electrode were measured. (author)

    Coxsackieviruses B (CV-B) (Picornaviridae) are a common infectious cause of acute myocarditis in children and young adults, a disease, which is a precursor to 10-20% of chronic myocarditis and dilated cardiomyopathy (DCM) cases. The mechanisms involved in the disease progression from acute to chronic myocarditis phase and toward the DCM clinical stage are not fully understood but are influenced by both viral and host factors. Subgenomic replicons of CV-B can be used to assess viral replication mechanisms in human cardiac cells and evaluate the effects of potential antiviral drugs on viral replication activities. Our objectives were to generate a reporter replicon from a cardiotropic prototype CV-B3/28 strain and to characterize its replication properties into human cardiac primary cells. To obtain this replicon, a cDNA plasmid containing the full CV-B3/28 genome flanked by a hammerhead ribozyme sequence and an MluI restriction site was generated and used as a platform for the insertion of sequences encoding emerald green fluorescent protein (EmGFP) in place of those encoding VP3. In vitro transcribed RNA from this plasmid was transfected into HeLa cells and human primary cardiac cells and was able to produce EmGFP and VP1-containing polypeptides. Moreover, non-structural protein biological activity was assessed by the specific cleavage of eIF4G1 by viral 2A(pro). Viral RNA replication was indirectly demonstrated by inhibition assays, fluoxetine was added to cell culture and prevented the EmGFP synthesis. Our results indicated that the EmGFP CV-B3 replicon was able to replicate and translate as well as the CV-B3/28 prototype strain. Our EmGFP CV-B3 replicon will be a valuable tool to readily investigate CV-B3 replication activities in human target cell models. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available Micropropagation techniques were set up for Gardenia jasminoides c.v. veitchi. Many plantlets were obtained by culturing shoot cuttings in MS nutrient media, 30 g/L Sucrose, 7 g/L Agar Agar, and different concentrations of BAP and IAA. The best concentration was 1mg /L BAP with 0.5 mg/L IAA. This concentration gave the best sprout growth suitable for rooting in primary and secondary culture by reculturing the stuck cutting every 6 weeks and for many times. We also obtained a high rooting percentage up to 98 % of natural rooting in rooting media different from propagation media by reducing mineral salt concentration to half, Sucrose to 20gm/L, and 2gm/L active charcoal, and 1mg/L IAA. Plantlets were transferred to greenhous and subjected for hardening. This technique gave 22 plantlets from one cutting in one year.

    1984-01-01

    The two textural varieties of olivine-rich Allende inclusions consist primarily of a porous, fine-grained mafic constituent that differs from the opaque meteorite matrix of CV3 chondrites by being relatively depleted in sulfides, metal grains, and carbonaceous material. Olivine is the most abundant mineral in Allende inclusion matrix; clinopyroxene, nepheline, sodalite, and Ti-Al-pyroxene occur in lesser amounts. Olivine in unrimmed olivine aggregates is ferrous and has a narrow compositional range. Olivine in rimmed olivine aggregates is, on average, more magnesian, with a wider compositional range. Olivine grains in the granular rims of Type 1B inclusions are zoned, with magnesian cores and ferrous rinds. Ferrous olivines in both varieties of inclusions commonly contain significant amounts of Al 2 O 3 , CaO and TiO 2 , refractory elements that probably occur in submicroscopic inclusions of Ca, Al, Ti-rich glass. Defocussed beam analyses of Allende matrix materials are discussed. (author)

    1988-01-01

    The distribution of photosynthetates, originating in leaves of different parts of the shoot of Vitis vinifera L. cv Cabernet Sauvignon at berry set, pea size, veraison and ripeness stages, was investigated. Specific photosynthetic activity of the 14 CO 2 -treated leaves gradually decreased during the season. Photosynthetates were hoarded in the leaves at berry set, but were increasingly diverted to the bunches after that. The apical leaves displayed the highest photosynthesis. The leaves opposite and below the bunches accumulated very little photosynthetates, especially from veraison to ripeness. Redistribution of photosynthetates among the basal, middle and apical leaves was generally very restricted at all stages. Multidirectional distribution from the site of application of 14 CO 2 occurred at berry set stage, while from pea size to ripeness photosynthetates were mainly translocated basipetally. Highest accumulation in the bunches occurred at veraison, while the basal leaves were primarily used to nourish the bunch

    Pigments of pericarp and pulp of pink guava (Psidium guajava L. cv. 'Criolla') were investigated to elucidate the profile and the accumulation of main carotenoids during four stages of fruit ripening by using HPLC-DAD and APCI-MS/MS analysis. Seventeen carotenoids were identified, and changes in their profile during fruit ripening were observed. The carotenoids all-trans-β-carotene, 15-cis-lycopene, and all-trans-lycopene were present in all ripening stages, but all-trans-lycopene was found to be predominant (from 63% to 92% of total carotenoids) and responsible for the high lipophilic antioxidant capacity determined by spectrophotometric assays. By using light and transmission electron microscopy, the development of chromoplasts in pericarp and pulp was demonstrated. The accumulation of all-trans-lycopene and all-trans-β-carotene coincided with the development of large crystals; the chromoplasts of pink guava belong, therefore, to the crystalline type.

    Zabrotes subfasciatus is a serious pest of common beans, P. vulgaris L.. In Brazil there are several studies dealing with resistance of bean genotypes to this insect, while other studies have emphasized the utilization of oils and powders from plants to repel their attack. In this paper, fecundity, fertility, pattern of oviposition, life cycle and longevity were evaluated for a Brazilian stock from the Goias State on P. vulgaris cv. Carioca, at 30 deg C and 70% R.H. The mean fecundity was 38 eggs per female and 73% of viability. Egg laying showed an aggregated pattern. Males and females lived an average of 13 and 9 days, respectively. The total life cycle lasted for about 28 days. (author)

    A transformation system for triploid bermudagrass ( Cynodon dactylon x C. transvaalensis cv. TifEagle) was established with a biolistic bombardment delivery system. Embryogenic callus was induced from stolons and maintained on Murashige and Skoog's medium supplemented with 30 microM dicamba, 20 microM benzylaminopurine, and 100 mg/l myo-inositol. Using the hygromycin phosphotransferase ( hpt) gene as the selectable marker gene, we obtained 75 transgenic lines from 18 petri dishes bombarded. Integration of the hpt gene into genomic DNA and transcription of hpt was confirmed by Southern and Northern blot analyses, respectively. Through suspension culture screening, we obtained homogeneously transformed plants showing stable transcription of the hpt gene.

    Transgenic Nicotiana tabacum L. cv. SR1 plants, characterized by an increase in the level of dsRNA-specific hydrolytic activity after induction by wounding, were obtained. The Solanum lycopersicum anionic peroxidase gene promoter (new for plant genetic engineering) was for the first time used for the induced expression of the target Serratia marcescens RNase III gene. Upon infection with the tobacco mosaic virus (TMV), the transgenic plants of the obtained lines did not differ significantly from the control group in the level of TMV capsid protein accumulation. In general, no delay in the development of the infection symptoms was observed in transgenic plants as compared with the control group. The obtained transgenic plants represent a new model for the study of the biological role of endoribonucleases from the RNase III family, including in molecular mechanisms of resistance to pathogens.

    Full Text Available A acerola é um fruto de grande potencial econômico e nutricional devido ao seu alto teor de vitamina C, destacando-se como alimento funcional. É comercializada principalmente na forma de polpa congelada e fruto in natura. O objetivo deste estudo foi avaliar a qualidade dos frutos da aceroleira cv. Olivier em dois estádios de maturação. Para tanto, foram colhidas amostras de frutos em um pomar comercial no município de Junqueirópolis-SP. Foram realizadas a determinação da cor externa dos frutos e análises das características químicas de teor de sólidos solúveis, pH, acidez titulável, açúcares redutores, 'ratio' e ácido ascórbico de frutos semi-maduros e maduros. Os resultados obtidos permitiram concluir que os frutos semimaduros apresentaram maior acidez total, menor teor de sólidos solúveis e menor concentração de açúcares; no entanto, estes frutos apresentaram maiores teores de vitamina C, expressa em ácido ascórbico. Portanto, quando se buscam altos índices de vitamina C, os frutos devem ser colhidos num estádio de maturação menos avançado, com coloração alaranjada. O estudo demonstrou também que a cv Olivier produz frutos com características adequadas tanto para o mercado in natura quanto para a indústria, apresentando boa coloração e características químicas dentro dos padrões para esta fruta.

    Full Text Available Este trabalho foi realizado com o objetivo de investigar o comportamento das enzimas pectina metilesterase (PME e β-galactosidase (β-Gal durante o amadurecimento do mamão cv.'Golden'. Mamões com 15% de cor amarela foram estocados em câmara de refrigeração a 20ºC e 85-95 % UR, por um período de 11 dias. Durante este período de estocagem, foi determinada a cor da casca, firmeza e pH da polpa dos frutos, bem como a atividade das enzimas PME e β-Gal. A atividade da PME, observada ao longo do amadurecimento do mamão, indicou que esta enzima participou do processo de hidrólise da parede celular, principalmente no início do amadurecimento dos frutos. Já a atividade da β-Gal aumentou, de maneira não gradual, do primeiro dia até o final do armazenamento, quando alcançou seu valor máximo. Uma redução drástica na firmeza e no pH da polpa ocorreu nos três primeiros dias de armazenamento. Neste período, os frutos apresentaram coloração com valores do ângulo hue próximos de 80, a qual corresponde a uma coloração amarela. Verificou-se que a PME atua de modo efetivo no amadurecimento do mamão, mas a redução precoce em sua atividade indica que a β-Gal tem também um papel fundamental na rápida perda de firmeza pelo mamão cv. Golden.

    An efficient in vitro propagation method has been developed for the first time for Musa acuminata (AAA) cv. Vaibalhla, an economically important banana cultivar of Mizoram, India. Immature male flowers were used as explants. Murashige and Skoog's (MS) medium supplemented with plant growth regulators (PGRs) were used for the regeneration process. Out of different PGR combinations, MS medium supplemented with 2 mg L(-1) 6-benzylaminopurine (BAP) + 0.5 mg L(-1) α-naphthalene acetic acid (NAA) was optimal for production of white bud-like structures (WBLS). On this medium, explants produced the highest number of buds per explant (4.30). The highest percentage (77.77) and number (3.51) of shoot formation from each explants was observed in MS medium supplemented with 2 mg L(-1) kinetin + 0.5 mg L(-1) NAA. While MS medium supplemented with a combination of 2 mg L(-1) BAP + 0.5 mg L(-1) NAA showed the maximum shoot length (14.44 cm). Rooting efficiency of the shoots was highest in the MS basal medium without any PGRs. The plantlets were hardened successfully in the greenhouse with 96% survival rate. Random amplified polymorphic DNA (RAPD) and inter-simple sequence repeat (ISSR) markers were employed to assess the genetic stability of in vitro regenerated plantlets of M. acuminata (AAA) cv. Vaibalhla. Eight RAPD and 8 ISSR primers were successfully used for the analysis from the 40 RAPD and 30 ISSR primers screened initially. The amplified products were monomorphic across all the regenerated plants and were similar to the mother plant. The present standardised protocol will find application in mass production, conservation and genetic transformation studies of this commercially important banana.

    This study was aimed to determine the effects of sodium azide on the performance of chili pepper. Dry seeds from pure lines of chili pepper cv. Landung were used in this experiment. Each set containing 50 seeds was placed in nylon fishner bags, washed in flowing water and soaked in distilled water for four hours. After soaking, four sets of seeds were dabbed dry with tissue paper and were treated for two hours at 30 0C in appropriate solution of 0, 0.10, 0.20, 0.40, 0.80, 1.60 mM sodium azide with phosphate buffer at pH 3. After treatment, the seeds were germinated in plastic boxes containing sterilized sand and kept under laboratory condition by supplied with water everyday. The seeds for M1 germination percentage, seedling height, plant height and number of leaves were recorded 30 days and 60 days after treatment, respectively. Seeds which radicle emerged were considered germinated, the seedling and plant height were measured from the tip of primary root to the base of the first leaf pair, and the number of leaves were counted for only fully expanded leaves. A completely randomized block design in four replicates was used throughout the experiment. Data obtained were analysed for range, mean, standard of deviation, and percent of control using Microsoft Office Excel 2007 software. It was concluded that different doses of sodium azide influenced the performances of chili pepper cv. Landung. Very low doses of sodium azide (0-1.60 mM) might be used to study the improvement of chili pepper diversity.

    Job satisfaction has been increasingly regarded as an important outcome of vocational rehabilitation programs among people with mental illness. Chinese measures of job satisfaction for individuals with mental illness are however extremely scarce. The aim of this study was to translate the 32-item Indiana Job Satisfaction Scale to Chinese. By means of the expert panel method, the culturally relevant 28-item Chinese Version of Indiana Job Satisfaction Scale (CV-IJSS) was then finalized. A validation study among a group of 125 individuals with mental illness showed that the scale had acceptable psychometric properties. Coefficient alpha of the total score was 0.81 with subscales ranging from 0.63 to 0.87. Test re-test reliability as measured by ICC was 0.77 for the total score and ranged from 0.54 to 0.72 for the subscales. Factorial analysis yielded a four factor solution (general satisfaction, job ambiguity and stress, advancement and security, and job recognition) accounting for 44% of the total variance. The factor solution had similarities as well as differences when compared with the Indiana Job Satisfaction Scale. The differences are discussed in the light of cultural differences. Relationship between scores of CV-IJSS and work performance, quality of life and self-esteem was positive in general which may act as evidence to its concurrent validity. The Chinese Version of Indiana Job Satisfaction Scale is ready for use by rehabilitation professionals to assess vocational rehabilitation outcome for individuals with mental illness in Hong Kong and other Chinese societies. Directions for further studies are suggested.

    A new and rapid protocol for optimum callus production and complete plant regeneration has been assessed in Malaysian upland rice (Oryza sativa) cv. Panderas. The effect of plant growth regulator (PGR) on the regeneration frequency of Malaysian upland rice (cv. Panderas) was investigated. Mature seeds were used as a starting material for callus induction experiment using various concentrations of 2,4-D and NAA. Optimal callus induction frequency at 90% was obtained on MS media containing 2,4-D (3 mg L(-1)) and NAA (2 mg L(-1)) after 6 weeks while no significant difference was seen on tryptophan and glutamine parameters. Embryogenic callus was recorded as compact, globular and light yellowish in color. The embryogenic callus morphology was further confirmed with scanning electron microscopy (SEM) analysis. For regeneration, induced calli were treated with various concentrations of Kin (0.5-1.5 mg L(-1)), BAP, NAA and 0.5 mg L(-1) of TDZ. The result showed that the maximum regeneration frequency (100%) was achieved on MS medium containing BAP (0.5 mg L(-1)), Kin (1.5 mg L(-1)), NAA (0.5 mg L(-1)) and TDZ (0.5 mg L(-1)) within four weeks. Developed shoots were successfully rooted on half strength MS free hormone medium and later transferred into a pot containing soil for acclimatization. This cutting-edge finding is unique over the other existing publishable data due to the good regeneration response by producing a large number of shoots.

    The C-V flap for nipple reconstruction is now one of standard surgical techniques. But decreased projection is still a problem. In recent years, it has been suggested that projection can be more easily maintained when raising of the C-flap is performed with a split thickness dermis. In this study, we examined whether decrease of projection can be prevented by raising of a C-flap with a split dermis rather than with full dermis. A total of 49 consecutive patients who underwent reconstruction of a nipple using the C-V flap technique were enrolled. The patients included 22 who underwent surgery using a C-flap with a full thickness dermis (Group F), and 27 who underwent surgery with raising of a flap with a split thickness dermis (Group S). The size of the reconstructed nipple was measured at 2 weeks, 6 months and 1 year postoperatively for comparison between Groups F and S. Partial necrosis of the C-flap end occurred in 4 subjects in only Group S. The decrease in projection after 1 year postoperatively in Group S was significantly lower than that in Group F. In contrast, the teat base size in Group F tended to be greater than that in Group S, suggesting a tendency for an expanded base using a flap with a full dermis. Our results indicated that it is recommended to use a C-flap with a split dermis for cases with high projection of the nipple on the contralateral side.

    Full Text Available This work aimed at comparing the growth and partitioning of assimilate in tomato plants cv. Micro-Tom subjected to nitrogen and pyraclostrobin. This substance favors the development of chloroplasts and the synthesis of chlorophyll. Tomato plants were submitted to the treatments: T1, complete nutrient solution without pyraclostrobin, T2, complete nutrient solution + pyraclostrobin, T3, ½ strength nutrient solution without N pyraclostrobin and T4, ½ strength nutrient solution N + pyraclostrobin. Plants were collected at regular intervals of seven days after transplantation throughout the crop cycle, with dry mass and leaf area being determined. From the primary data, growth analysis was carried out to calculate total dry matter (Wt, the instantaneous rates of dry matter production (Ct, relative growth (Rw e net assimilation (Ea, leaf area (Af, production rates (Ca and relative growth of leaf area index (Ra and leaf weight (Fw specific leaf area (Sa the dry matter partitioning between organs and number (Nfr and fresh fruit weight (Wfr. Plants of T1 showed higher Wt, Ct and Wfr compared to those of other treatments. However, the T2 plants exhibited similar Nfr to T1 plants, being superior to others. Also allocated on the total dry matter and at the end of the cycle, a higher percentage of dry matter in the seafood compared to T3 and T4 plants. Also they allocated relative to the total dry matter and at the end of the cycle, a higher percentage in fruits of plants to T3 and T4. The association between nitrogen and pyraclostrobin changes the growth and assimilated partition on tomato plants cv. Micro – Tom, and those submitted to ½ dose of nitrogen have a higher total dry matter and less final percentage of total dry matter in fruits , comparatively to those submitted to the association ½ dose of nitrogen and pyraclostrobin.

    Full Text Available The purpose of this research was to study the effect of CV and SEV curing systems on aging and thermal properties of natural rubber and butyl rubber blends. The mixing of rubber and rubber chemicals using two roll-mills and the vulcanization process was carried out by the hydraulic press at 160° C and 150 kg/cm2. The research design used two variations; first, the CV curing system (accelerator/sulfur (1.0/2.5 phr and SEV curing system (accelerator/sulfur (2.1/1.5 phr, second, the ratio of natural rubber/butyl: 100/0; 95/5; 90/10; 85/15; 80/20; 75/25; 70/30; 65/35; 60/40 and 55/45 phr. The parameter observed were tensile strength, elongation at break, hardness before and after aging and thermal properties, e.g.TG/DTA and DSC. The results showed that CV curing systems provided tensile, elongation at break properties gave higher quality and better aging properties. TG/DTA analysis of vulcanizates processed with CV curing systems provided slightly better thermal stability than of the SEV curing system.

    Transplantation of a myogenic cell population into an immunodeficient recipient is an excellent way of assessing the in vivo muscle-generating capacity of that cell population. To facilitate both allogeneic and xenogeneic transplantations of muscle-forming cells in mice we have developed a novel immunodeficient muscular dystrophy model, the NSG-mdx4Cv mouse. The IL2Rg mutation, which is linked to the Dmd gene on the X chromosome, simultaneously depletes NK cells and suppresses thymic lymphomas, issues that limit the utility of the SCID/mdx model. The NSG-mdx4Cv mouse presents a muscular dystrophy of similar severity to the conventional mdx mouse. We show that this animal supports robust engraftment of both pig and dog muscle mononuclear cells. The question of whether satellite cells prospectively isolated by flow cytometry can confer a functional benefit upon transplantation has been controversial. Using allogeneic Pax7-ZsGreen donors and NSG-mdx4Cv recipients, we demonstrate definitively that as few as 900 FACS-isolated satellite cells can provide functional regeneration in vivo, in the form of an increased mean maximal force-generation capacity in cell-transplanted muscles, compared to a sham-injected control group. These studies highlight the potency of satellite cells to improve muscle function, and the utility of the NSG-mdx4Cv model for studies on muscle regeneration and Duchenne muscular dystrophy therapy.

    Every year, billions of tons of eroded mineral soils from the Saharan Desert and the Sahel region, the largest dust source in the world, cross Mediterranean towards Europe, western Asia and the tropical North Atlantic Ocean as far as the Caribbean and South America. Many aspects of the direct and indirect effects of dust on climate are not well understood and the bulk and surface chemistry of the mineral dust particles determines interactions with gaseous and other particle species. The quantification of the magnitude of warming or cooling remains open because of the strong variability of the atmospheric dust burden and the lack of representative data for the spatial and temporal distribution of the dust composition. CV-Dust is a project that aims at provide a detailed data on the size distribution and the size-resolved chemical and mineralogical composition of dust emitted from North Africa using a natural laboratory like Cape Verde. This archipelago is located in an area of massive dust transport from land to ocean, and is thus ideal to set up sampling devices that are able to characterize and quantify dust transported from Africa. Moreover, Cape Verde's future economic prospects depend heavily on the encouragement of tourism, therefore it is essential to elucidate the role of Saharan dust may play in the degradation of Cape Verde air quality. The main objectives of CV-Dust project are: 1) to characterize the chemical and mineralogical composition of dust transported from Africa by setting up an orchestra of aerosol sampling devices in the strategic archipelago of Cape Verde; 2) to identify the sources of particles in Cape Verde by using receptor models; 3) to elucidate the role Saharan dust may play in the degradation of Cape Verde air quality; 4) to model processes governing dust production, transport, interaction with the radiation field and removal from the atmosphere. Here we present part of the data obtained throughout the last year, involving a set of more

    A new live attenuated Japanese encephalitis chimeric virus vaccine (JE-CV) has been developed based on innovative technology to give protection against JE with an improved immunogenicity and safety profile. In this phase 3, observer-blind study, 274 children aged 12-24 months were randomized 1:1 to receive one dose of JE-CV (Group JE-CV) or the SA14-14-2 vaccine currently used to vaccinate against JE in the Republic of Korea (Group SA14-14-2). JE neutralizing antibody titers were assessed using PRNT50 before and 28 days after vaccination. The primary endpoint of non-inferiority of seroconversion rates on D28 was demonstrated in the Per Protocol analysis set as the difference between Group JE-CV and Group SA14-14-2 was 0.9 percentage points (95% confidence interval [CI]: -2.35; 4.68), which was above the required -10%. Seroconversion and seroprotection rates 28 days after administration of a single vaccine dose were 100% in Group JE-CV and 99.1% in Group SA14-14-2; all children except one (Group SA14-14-2) were seroprotected. Geometric mean titers (GMTs) increased in both groups from D0 to D28; GM of titer ratios were slightly higher in Group JE-CV (182 [95% CI: 131; 251]) than Group SA14-14-2 (116 [95% CI: 85.5, 157]). A single dose of JE-CV was well tolerated and no safety concerns were identified. In conclusion, a single dose of JE-CV or SA14-14-2 vaccine elicited a comparable immune response with a good safety profile. Results obtained in healthy Korean children aged 12-24 months vaccinated with JE-CV are consistent with those obtained in previous studies conducted with JE-CV in toddlers.

    Full Text Available In this work, cuticular waxes from flag leaf blades and peduncles of Triticum aestivum cv. Bethlehem were investigated in search for novel wax compounds. Seven wax compound classes were detected that had previously not been reported, and their structures were elucidated using gas chromatography-mass spectrometry of various derivatives. Six of the classes were identified as series of homologs differing by two methylene units, while the seventh was a homologous series with homologs with single methylene unit differences. In the waxes of flag leaf blades, secondary alcohols (predominantly C27 and C33, primary/secondary diols (predominantly C28 and esters of primary/secondary diols (predominantly C50, combining C28 diol with C22 acid were found, all sharing similar secondary hydroxyl group positions at and around C-12 or ω-12. 7- and 8-hydroxy-2-alkanol esters (predominantly C35, 7- and 8-oxo-2-alkanol esters (predominantly C35, and 4-alkylbutan-4-olides (predominantly C28 were found both in flag leaf and peduncle wax mixtures. Finally, a series of even- and odd-numbered alkane homologs was identified in both leaf and peduncle waxes, with an internal methyl branch preferentially on C-11 and C-13 of homologs with even total carbon number and on C-12 of odd-numbered homologs. Biosynthetic pathways are suggested for all compounds, based on common structural features and matching chain length profiles with other wheat wax compound classes.

    An adequate nutritional state of a crop can be kept by means of a well-designed fertilization plan based on the assessment of the nutrient availability throughout the growing season. The objective of this study was to determine the reliability of leaf blade and petiole diagnosis and the period of validity of their references at both flowering and veraison by means of systematic monitoring throughout the complete growing season. The study was carried out in two plots planted with Vitis vinifera L. cv. Graciano within the AOC Rioja (Spain). Blades and petioles were collected throughout a growing season (2006) and total N, P, K, Ca, Mg, Fe, Mn, Zn, Cu and B concentrations were analyzed in both tissues. Results suggest, in general, that petioles have higher variability and lower analysis reproducibility than blades. Therefore, blade could be a more appropriate tissue to evaluate N, P, K, Ca, and Mg at both flowering and veraison in this variety. Micronutrients in blade and petiole showed different variability behaviour in each of the vineyards studied, therefore, based on our results, it was difficult to determine which one could be the best tissue for the nutritional diagnosis of the ‘Graciano’ variety. Seasonal changes of nutrient concentration in both tissues also confirmed the need for reference values for each tissue and each phenological stage. (Author)

    We have analysed the petrography, major element abundances and bulk Al-Mg isotope systematics of 19 ferromagnesian chondrules from the CV3 chondrites Allende, Mokoia, and Vigarano, together with an Al-rich chondrule and refractory olivine from Mokoia. Co-variations of Al/Mg with Na/Mg and Ti/Mg in our bulk chondrules suggest their compositions are dominantly controlled by reworking of different proportions of chondrule components (e.g. mafic minerals and mesostatis); their precursors are thus fragments from prior generations of chondrules. Our samples show a range in fractionation corrected 26Mg/24Mg (Δ‧26Mg) ∼ 60 ppm, relative to precisions behaviour once 26Al was effectively extinct ((26Al/27Al)0 3.4 ± 0.6 × 10-5. Overall, our samples record a sequence of events from the formation of ferromagnesian objects within 0.5 Ma of CAI to re-equilibration of chondrules and silicate vapour >2 Ma post CAI, assuming an initially homogeneous 26Al/27Al. Metamorphism on the asteroid parent body may have played a subsequent role in affecting Mg isotope composition, but we argue this had a minor influence on the observations here.

    A powerful characterization technique, pulse capacitance-voltage (CV) technique, was used to investigate oxide traps before and after annealing for lanthanide zirconium oxide thin films deposited on n-type Si (111) substrates at 300 °C by liquid injection Atomic Layer Deposition (ALD). The results indicated that: (1) more traps were observed compared to the conventional capacitance-voltage characterization method in LaZrO x ; (2) the time-dependent trapping/de-trapping was influenced by the edge time, width and peak-to-peak voltage of a gate voltage pulse. Post deposition annealing was performed at 700 °C, 800 °C and 900 °C in N₂ ambient for 15 s to the samples with 200 ALD cycles. The effect of the high temperature annealing on oxide traps and leakage current were subsequently explored. It showed that more traps were generated after annealing with the trap density increasing from 1.41 × 10 12 cm -2 for as-deposited sample to 4.55 × 10 12 cm -2 for the 800 °C annealed one. In addition, the leakage current density increase from about 10 - ⁶ A/cm² at V g = +0.5 V for the as-deposited sample to 10 -3 A/cm² at V g = +0.5 V for the 900 °C annealed one.

    Full Text Available We studied 49 patients with partial epilepsy divided into lesional cases (i.e. with lesions on CT scan and non-lesional cases (i.e. without CT scan lesions, in relation to the Wechsler Intelligence Scale subtests (Coding, Digit span, dichotic listening CV task and Central Auditory Test (SSI, PSI. The aim of this paper was to study the hemispheric prevalence in dichotic listening task with regard to cognitive perforamance, as well as the presence or absence of central auditory dysfunction. Lesional cases presented a hemisphere prevalence in dichotic listening task with regard to cognitive performance, as well as the non-lesional cases tend to report the stimuli in the same side of EEC focus. Significant differences were found among the lesional and non lesional cases in relation to the digit span score and Coding subtest in right lesional cases versus right non-lesional cases. Both lesional and non-lesional group showed signs of central auditory dysfunction. We suggest that the dichotic listening and SSI and PSI test can be useful for a best comprehension of asymmetric neuropsychological performance in partial epilepsy.

    Full Text Available The aim of this study was to evaluate the effect of an ethanol extract of the rhizomes of Dioscorea alata L. cv. Phyto, Dispo85E, on bone formation and to investigate the mechanisms involved. Our results showed that Dispo85E increased the activity of alkaline phosphatase (ALP and bone nodule formation in primary bone marrow cultures. In addition, Dispo85E stimulated pluripotent C3H10T1/2 stem cells to differentiate into osteoblasts rather than adipocytes. Our in vivo data indicated that Dispo85E promotes osteoblastogenesis by increasing ALP activity and bone nodule formation in both intact and ovariectomized (OVX mice. Microcomputed tomography (μCT analysis also showed that Dispo85E ameliorates the deterioration of trabecular bone mineral density (tBMD, trabecular bone volume/total volume (BV/TV, and trabecular bone number (Tb.N in OVX mice. Our results suggested that Dispo85E is a botanical drug with a novel mechanism that drives the lineage-specific differentiation of bone marrow stromal cells and is a candidate drug for osteoporosis therapy.
