  2. Transcendental numbers

    CERN Document Server

    Murty, M Ram

    2014-01-01

    This book provides an introduction to the topic of transcendental numbers for upper-level undergraduate and graduate students. The text is constructed to support a full course on the subject, including descriptions of both relevant theorems and their applications. While the first part of the book focuses on introducing key concepts, the second part presents more complex material, including applications of Baker’s theorem, Schanuel’s conjecture, and Schneider’s theorem. These later chapters may be of interest to researchers interested in examining the relationship between transcendence and L-functions. Readers of this text should possess basic knowledge of complex analysis and elementary algebraic number theory.

    In Early Transcendentals (The American Mathematical Monthly, Vol. 104, No 7) Steven Weintraub presents a rigorous justifcation of the "early transcendental" calculus textbook approach to the exponential and logarithmic functions. However, he uses tools such as term-by-term differentiation of infinite series. We present a rigorous treatment of the early transcendental approach suitable for a first course in analysis, using mainly the supremum property of the real numbers.

  5. Transcendental idealism and structuralism

    Directory of Open Access Journals (Sweden)

    Ivan Vuković

    2016-02-01

    Full Text Available The author examines possible analogies between Kant’s transcendental idealism and de Saussure’s and Levi-Strauss’s structuralism, in order to analyse if the former can be understood as a predecessor for the later. The author shows that both teachings assume a priori formal framework, but they diverge in the ways they describe it, as well as in understanding of its function. Consequently, the author concludes that structuralism can be seen as one possible use of Kant’s idea about the existence of such a frame. Furthermore, the author claims that Ricker’s understanding of structuralism as ‘Kantianism without transcendental subject’ should be rejected, since a teaching which does not assume existence of such subject cannot be understood as Kantian.

  6. Transcendental Philosophy and its Transformations

    DEFF Research Database (Denmark)

    Ishihara, Yuko

    There is an interesting overlap between Heidegger and Nishida that has not gained attention in the literature. During the late 1920s, both philosophers looked to transcendental philosophy as a way to overcome the Western metaphysical tradition. Neither philosopher, however,simply accepted...... traditional forms of transcendental philosophy. Rather, both attempted to transform it from within. In this work, I aim to articulate the extent to which Heidegger and Nishidastill worked within a traditional transcendental framework and also the ways in which they attempt to transform transcendental...... philosophy. I argue that while Heidegger’s “hermeneutic” and Nishida’s “chorological” (I employ this term from Plato’s chōra) transformations have much in common, the latter is more radical than the former. Specifically, Nishida reveals the pre-reflective origin of transcendental reflection not in the pre...

  7. Transcendental experiences during meditation practice.

    Travis, Frederick

    2014-01-01

    This article explores transcendental experiences during meditation practice and the integration of transcendental experiences and the unfolding of higher states of consciousness with waking, dreaming, and sleeping. The subject/object relationship during transcendental experiences is characterized by the absence of time, space, and body sense--the framework that gives meaning to waking experiences. Physiologically, transcendental experiences during Transcendental Meditation practice are marked by slow inhalation, along with autonomic orientation at the onset of breath changes and heightened α1 (8-10 Hz) frontal coherence. The integration of transcendental experiences with waking, dreaming, and sleeping is also marked by distinct subjective and objective markers. This integrated state, called Cosmic Consciousness in the Vedic tradition, is subjectively marked by inner self-awareness coexisting with waking, sleeping, and dreaming. Physiologically, Cosmic Consciousness is marked by the coexistence of α1 electroencephalography (EEG) with delta EEG during deep sleep, and higher brain integration, greater emotional stability, and decreased anxiety during challenging tasks. Transcendental experiences may be the engine that fosters higher human development. © 2013 New York Academy of Sciences.

  8. TRANSCENDENTAL ASPECTS OF GENDER

    2014-06-01

    Full Text Available This paper aims to analyze the basic principles of gender philosophy applying methodological tools of communicative pragmatics; to demonstrate how gender construct can provide gender humanism formation as one of the ideals of democratic society; to specify gender glossary terms such as “gender democracy”, “gender equality” and “gender justice”. Methodology. In order to investigate a theoretical framework in feminist philosophy, methodological tools of communicative pragmatics and discursive ethics that were elaborated by modern German philosophers J. Habermas, K.-O. Apel for analyzing ethical gender principles and their legitimation ways have been used in this research. Scientific novelty. Based on methodological differences in concepts of J. Habermas and K.-O. Apel, two opposite approaches to gender concept analysis – rational and pragmatic (Habermas and transcendental conceptual (K.-O. Apel have been found out. The article helps to specify the framework of categories and concepts. According to the legitimation way of gender ethical theory it was discovered that such notions as “gender democracy”, “gender equality” and “gender justice” do not have the same meanings. According to the analysis of communicative action program and consensus, the “gender equality” concept by Habermas is an artificial social construct that is methodologically grounded in cognitivism and diminishes the possibilities of gender values legitimation. According to K.-O. Apel, the concept of “gender justice” is based on transcendental moral and ethical sense of opposite genders unity and does not discharge unequal distribution of responsibilities and any invasion as well as represents certain extent of their difference. Conclusions. Fast growing gender changes in the society face ageold drawbacks of moral and spiritual principles of communities, taking into account social and cultural, national and gender identity.

  10. Philosophy of biology: naturalistic or transcendental?

    Science.gov (United States)

    Kolen, Filip; Van de Vijver, Gertrudis

    2007-01-01

    The aim of this article is to clarify the meaning of a naturalistic position within philosophy of biology, against the background of an alternative view, founded on the basic insights of transcendental philosophy. It is argued that the apparently minimal and neutral constraints naturalism imposes on philosophy of science turn out to involve a quite heavily constraining metaphysics, due to the naturalism's fundamental neglect of its own perspective. Because of its intrinsic sensitivity to perspectivity and historicity, transcendental philosophy can avoid this type of hidden metaphysics.

    The application of different limit processes to a physical problem is an important tool in layer type techniques. Hence the study of initial layer correction functions is of central importance for understanding layer-type problems. It is shown that for singularly perturbed problems of Volterra type, the concept of transcendental smallness is an asymptotic one. Transcendentally small terms may be numerically important. (author)

    Petitot, Jean

    1. The more mathematics and physics unify themselves in the physico-mathematical modern theories, the more an objective epistemology becomes necessary. Only such a transcendental epistemology is able to thematize correctly the status of the mathematical determination of physical reality. 2. There exists a transcendental history of the synthetic a priori and of the construction of physical categories. 3. The transcendental approach allows to supersed Wittgenstein's and Carnap's antiplatonist thesis according to which pure mathematics are physically applicable only if they lack any descriptive, cognitive or objective, content and reduce to mere prescriptive and normative devices. In fact, pure mathematics are prescriptive-normative in physics because: (i) the categories of physical objectivity are prescriptive-normative, and (ii) their categorial content is mathematically “constructed” through a Transcendental Aesthetics. Only a transcendental approach make compatible, in the one hand, a grammatical conventionalism of Wittgensteinian or Carnapian type and, on the other hand, a platonist realism of Gödelian type. Mathematics are not a grammar of the world but a mathematical hermeneutics of the intuitive forms and of the categorial grammar of the world.

  1. The vital role of transcendental truth in science.

    Science.gov (United States)

    Charlton, Bruce G

    2009-04-01

    I have come to believe that science depends for its long-term success on an explicit and pervasive pursuit of the ideal of transcendental truth. 'Transcendental' implies that a value is ideal and ultimate - it is aimed-at but can only imperfectly be known, achieved or measured. So, transcendental truth is located outside of science; beyond scientific methods, processes and peer consensus. Although the ultimate scientific authority of a transcendental value of truth was a view held almost universally by the greatest scientists throughout recorded history, modern science has all-but banished references to truth from professional scientific discourse - these being regarded as wishful, mystical and embarrassing at best, and hypocritical or manipulative at worst. With truth excluded, the highest remaining evaluation mechanism is 'professional consensus' or peer review - beyond which there is no higher court of appeal. Yet in Human accomplishment, Murray argues that cultures which foster great achievement need transcendental values (truth, beauty and virtue) to be a live presence in the culture; such that great artists and thinkers compete to come closer to the ideal. So a scientific system including truth as a live presence apparently performs better than a system which excludes truth. Transcendental truth therefore seems to be real in the pragmatic sense that it makes a difference. To restore the primacy of truth to science a necessary step would be to ensure that only truth-seekers were recruited to the key scientific positions, and to exclude from leadership those who are untruthful or exhibit insufficient devotion to the pursuit of truth. In sum, to remain anchored in its proper role, science should through 'truth talk' frequently be referencing normal professional practice to transcendental truth values. Ultimately, science should be conducted at every level, from top to bottom, on the basis of what Bronowski termed the 'habit of truth'. Such a situation currently

  3. Kantian Feeling: Empirical Psychology, Transcendental Critique, and Phenomenology

    Directory of Open Access Journals (Sweden)

    Patrick Frierson

    2016-06-01

    Full Text Available This paper explores the relationship between empirical psychology, transcendental critique, and phenomenology in Kant’s discussion of respect for the moral law, particularly as that is found in the Critique of Practical Reason. I first offer an empirical-psychological reading of moral respect, in the context of which I distinguish transcendental and empirical perspectives on moral action and defend H. J. Paton’s claim that moral motivation can be seen from two points of view, where “from one point of view, [respect] is the cause of our action, but from another point of view the moral law is its ground.” Then, after a discussion of a distinction between first- and second-order transcendental/practical perspectives where reasons for action are first-order practical judgments while the conditions of possibility for those reasons’ authority are expressed in second-order judgments, I turn to a third kind of perspective: the properly phenomenological one. I explain the general notion of Kantian phenomenology with an example of the experience of time from Kant’s Anthropology before applying this to a phenomenological reading of the discussion of respect in the Critique of Practical Reason. I end by noting that on my account, in contrast to that of Jeanine Grenberg, the distinctive phenomenology of respect is not systematically important for grounding claims in moral philosophy.

Elaborated explanation in this paper is expected to result in a true understanding of this crucial issue, particularly the concept of religious pluralism in the discourse of Islamic studies. Ibn Arabi’ extensively  discusses religion in the sense of the “ideal” versus “historical” or “esoteric” versus “the exoteric”. Ibn ‘Arabi concludes that the absolute unity of religions may only occur within spiritual, ideal, or transcendental realm (or “esoteric”, which is beyond the formal form of religions. Hence, the transcendental unity of religions cannot be found in the formal form of religions nor in the shari’ah.[Artikel ini mengulas pandangan Ibn ‘Arabi’ mengenai wahdat al-adyan seperti dijelaskan dalam dua bukunya; Futuhat dan Fusus, dan perbedaan dan kesamaan antara iman dan shariah. Diharapkan diskusi artikel ini berkontribusi dalam kajian pluralisme, utamanya dalam disiplin studi Islam. Dalam diskusinya, Ibn Arabi’  menjelaskan perbedaan ‘ideal’ dan ‘historikal’ atau antara ‘esoterik’ dan ‘eksoterik’. Ibn ‘Arabi berpendapat bahwa kemanunggalan agama-agama dapat dicapai melalui spiritualitas, ideal, atau dimensi transcendental (esoterik yang ada di luar tampilan formal agama-agama.

  5. The embodied transcendental: a Kantian perspective on neurophenomenology.

    Science.gov (United States)

    Khachouf, Omar T; Poletti, Stefano; Pagnoni, Giuseppe

    2013-01-01

    Neurophenomenology is a research programme aimed at bridging the explanatory gap between first-person subjective experience and neurophysiological third-person data, through an embodied and enactive approach to the biology of consciousness. The present proposal attempts to further characterize the bodily basis of the mind by adopting a naturalistic view of the phenomenological concept of intentionality as the a priori invariant character of any lived experience. Building on the Kantian definition of transcendentality as "what concerns the a priori formal structures of the subject's mind" and as a precondition for the very possibility of human knowledge, we will suggest that this transcendental core may in fact be rooted in biology and can be examined within an extension of the theory of autopoiesis. The argument will be first clarified by examining its application to previously proposed elementary autopoietic models, to the bacterium, and to the immune system; it will be then further substantiated and illustrated by examining the mirror-neuron system and the default mode network as biological instances exemplifying the enactive nature of knowledge, and by discussing the phenomenological aspects of selected neurological conditions (neglect, schizophrenia). In this context, the free-energy principle proposed recently by Karl Friston will be briefly introduced as a rigorous, neurally-plausible framework that seems to accomodate optimally these ideas. While our approach is biologically-inspired, we will maintain that lived first-person experience is still critical for a better understanding of brain function, based on our argument that the former and the latter share the same transcendental structure. Finally, the role that disciplined contemplative practices can play to this aim, and an interpretation of the cognitive processes taking place during meditation under this perspective, will be also discussed.

    2013-07-01

    Full Text Available On the basis of Eugen Fink’s insistence that the true contribution of Kant’s transcendental dialectic is that its treatment of the problem of totality reveals the concept ‘totum’ to be a masking of the nothing, our aim is to highlight that the theory of sexual relation introduced by Lacan in his Seminar Encore –and in general his turn to the real from the 1960 onwards– presents a group of features that make clear its Kantian affiliation. The particular analysis of the logic of illusion contained in Lacan’s formulas of sexuation entail the exposure of three nothings: the impossibility of the sexual relation, the non-existence of The woman, and the absence of the Other of the Other.

    Form factors of composite operators in the SL(2) sector of N=4 SYM theory are studied up to two loops via the on-shell unitarity method. The non-compactness of this subsector implies the novel feature and technical challenge of an unlimited number of loop momenta in the integrand’s numerator. At one loop, we derive the full minimal form factor to all orders in the dimensional regularisation parameter. At two loops, we construct the complete integrand for composite operators with an arbitrary number of covariant derivatives, and we obtain the remainder functions as well as the dilatation operator for composite operators with up to three covariant derivatives. The remainder functions reveal curious patterns suggesting a hidden maximal uniform transcendentality for the full form factor. Finally, we speculate about an extension of these patterns to QCD.

    Full Text Available Several approaches exist for organizing and analyzing data in a phenomenological qualitative study. Transcendental phenomenology, based on principles identified by Husserl (1931 and translated into a qualitative method by Moustakas (1994, holds promise as a viable procedure for phenomenological research. However, to best understand the approach to transcendental phenomenology, the procedures need to be illustrated by a qualitative study that employs this approach. This article first discusses the procedures for organizing and analyzing data according to Moustakas (1994. Then it illustrates each step in the data analysis procedure of transcendental phenomenology using a study of reinvestment or the “ripple effect” for nine individuals who have participated in a youth leadership mentoring program from the 1970s to the present. Transcendental phenomenology works well for this study as this methodology provides logical, systematic, and coherent design elements that lead to an essential description of the experience.

  2. Negotiating Transcendentalism, Escaping « Paradise » : Herman Melville’s Moby-Dick.

    Directory of Open Access Journals (Sweden)

    Ramón Espejo Romero

    2010-06-01

    Full Text Available By reviewing the critical literature on Melville and Transcendentalism and then undertaking a close reading of Moby-Dick (1851, this paper argues that the novel reflects, among other things, an ongoing debate between the novelist and Transcendentalist philosophy. While in later works, Melville seems to express a more robust condemnation of the Concord movement and its dangerous idealism, Moby-Dick occupies less firmly-defined territory. The Transcendentalist urge of an Ahab to be himself is a counterpoint to Ishmael’s more idiosyncratic deployment of self-reliance, communion with the oversoul, and various other concepts easy to trace back to Emerson or Thoreau. The conclusion seems to be that a negotiation is necessary if Transcendentalism is to be heeded at all, precisely the kind of negotiation Ishmael undertakes throughout the novel, one which spares him from the maelstrom created by a more radical approach to self-acceptance and self-fashioning.

    The structures of Bu-2470 A, B1, B2a, and B2b have been determined. Bu-2470 A is a simple octapeptide having no fatty acid moiety, while Bu-2470 B1, B2a and B2b are octapeptides that have been acylated with a beta-hydroxy C11 or C10 fatty acid. The octapeptide structure of Bu-2470 components was found identical with that of octapeptin C1, hence generic names of octapeptin C0, C2, C3 and C4 are proposed for Bu-2470 A, B1, B2a and B2b, respectively.

    Full Text Available A randomized wait-list controlled trial (=295 university students of the effects of the Transcendental Meditation program was conducted in an urban setting. Substance use was assessed by self-report at baseline and 3 months later. For smoking and illicit drug use, there were no significant differences between conditions. For alcohol use, sex X intervention condition interactions were significant; TM instruction lowered drinking rates among male but not female students. TM instruction could play a valuable role in reducing alcohol use among male university students. Limitations are noted, along with suggestions for further research.

  8. Conformity visa-vi transformational conversion in mission: Towards a self-transcendental mission agenda

    Directory of Open Access Journals (Sweden)

    Selaelo T. Kgatla

    2017-09-01

    Full Text Available In this article, the author discusses the concept of conversion as opposed to conformity to  a  religious tradition without internal self-assertiveness. A transcendental mission understanding as opposed to an immanent agenda for liberation is proposed as an alternative solution. He analyses the role played and the contributions made by missionary enterprise and the liberation theologies in South Africa as they shaped the path for liberation. The white churches and state theologies sought to produce black conformists to the system; liberation theologies resisted the conformity mentality and fought for an egalitarian and free society. Both movements failed to embrace a transcendental methodology that would go beyond the secular boundaries and bring about transformational and empowering spirituality. This article suggests new spirituality for life and affirmation that would work against self-hate among the previously oppressed and self-guilt among the previously oppressing ruling class. It seeks ways to heal broken relationships through authentic empowerment and transformation.

    The complexes [MeBu{sub 3}N]{sub 2}[UCl{sub 6}] and [BuMe{sub 2}Im]{sub 2}[UCl{sub 6}] were characterized in the solid state and in solution of [MeBu{sub 3}N][Tf{sub 2}N], [BuMe{sub 2}Im][Tf{sub 2}N] and [BuMeIm][Tf{sub 2}N] room temperature ionic liquids using single-crystal XRD, EXAFS, electrochemistry, UV-visible absorption spectroscopy and NMR. In the solid and in solution, the existence of hydrogen bonding between the anionic UCl{sub 6}{sup 2-} complex and the ionic liquid cations were revealed by these techniques. The MeBu{sub 3}N{sup +} cation interacts with UCl{sub 6}{sup 2-} via the protons on the alpha carbon atoms of nitrogen. The protons of the imidazolium ring account for the interaction between the BuMe{sub 2}Im+ cation and the UCl{sub 6}{sup 2-} anion. For the BuMeIm{sup +} cation the major interaction was confirmed between the most acidic proton on C(2) and UCl{sub 6}{sup 2-}. The experimental results also show that the intensity of the interaction between the UCl{sub 6}{sup 2-} anion and the cation varies with the ionic liquid cation in the following order: MeBu{sub 3}N{sup +} {approx} BuMe{sub 2}Im{sup +} << BuMeIm{sup +}.

    Walton, Kenneth G; Schneider, Robert H; Salerno, John W; Nidich, Sanford I

    2005-01-01

    Cardiovascular disease (CVD) remains the leading cause of death in the United States today and a major contributor to total health care costs. Psychosocial stress has been implicated in CVD, and psychosocial approaches to primary and secondary prevention are gaining research support. This third article in the series on psychosocial stress and CVD continues the evaluation of one such approach, the Maharishi Transcendental Meditation program, a psychophysiological approach from the Vedic tradition that is systematically taught by qualified teachers throughout the world. Evidence suggests not only that this program can provide benefits in prevention but also that it may reduce CVD-related and other health care expenses. On the basis of data from the studies available to date, the Transcendental Meditation program may be responsible for reductions of 80% or greater in medical insurance claims and payments to physicians. This article evaluates the implications of research on the Transcendental Meditation program for health care policy and for large-scale clinical implementation of the program. The Transcendental Meditation program can be used by individuals of any ethnic or cultural background, and compliance with the practice regimen is generally high. The main steps necessary for wider adoption appear to be: (1) educating health care providers and patients about the nature and expected benefits of the program, and (2) adjustments in public policies at the state and national levels to allow this program to be included in private and public health insurance plans.

  15. Retrogressive development: transcendental anatomy and teratology in nineteenth-century Britain.

    Science.gov (United States)

    Bates, Alan W H

    2014-01-01

    In 1855 the leading British transcendental anatomist Robert Knox proposed a theory of retrogressive development according to which the human embryo could give rise to ancestral types or races and the animal embryo to other species within the same family. Unlike monsters attributed to the older theory of arrested development, new forms produced by retrogression were neither imperfect nor equivalent to a stage in the embryo's development. Instead, Knox postulated that embryos contained all possible specific forms in potentia. Retrogressive development could account for examples of atavism or racial throwbacks, and formed part of Knox's theory of rapid (saltatory) species change. Knox's evolutionary theorizing was soon eclipsed by the better presented and more socially acceptable Darwinian gradualism, but the concept of retrogressive development remained influential in anthropology and the social sciences, and Knox's work can be seen as the scientific basis for theories of physical, mental and cultural degeneracy.

  16. A Padé approximant approach to two kinds of transcendental equations with applications in physics

    International Nuclear Information System (INIS)

    Luo, Qiang; Wang, Zhidan; Han, Jiurong

    2015-01-01

    In this paper, we obtain the analytical solutions of two kinds of transcendental equations with numerous applications in college physics by means of the Lagrange inversion theorem. Afterwards we rewrite them in the form of a ratio of rational polynomials by a second-order Padé approximant from a practical and instructional perspective. Our method is illustrated in a pedagogical manner for the benefit of students at the undergraduate level. The approximate formulas introduced in the paper can be applied to abundant examples in physics textbooks, such as Fraunhofer single-slit diffraction, Wien’s displacement law, and the Schrödinger equation with single- or double-δ potential. These formulas, consequently, can reach considerable accuracies according to the numerical results; therefore, they promise to act as valuable ingredients in the standard teaching curriculum.

  17. The legitimating fact in the transcendental deduction of the categories: on Dieter Henrich's reading of Kant

    Directory of Open Access Journals (Sweden)

    Christian Klotz

    Full Text Available This article reconstructs the principal moments of Dieter Henrich's work on Immanuel Kant's theoretical philosophy. Henrich seeks to clarify and regain the fundaments of Kant's theory of knowledge - from which his followers, according to him, have distanced themselves - based on the analysis of the "transcendental deduction of the categories". Firstly, Henrich investigates the proof structure of deduction, comparing the first and the second edition of Critique of Pure Reason. Secondly, he investigates, in the Kantian argument, the relationship between the identity principle of self-consciousness and objectivity. Finally, extending the comparison to Critique of Practical Reason, Henrich elucidates the program and methodology in deduction, showing that the idea of a legitimating fact, borrowed from the juridical notion of a deduction, becomes the fundamental element. We analyse the problems raised by the conception of a philosophical argument based on fundamental "facts".

    2016-05-01

    The objective of this study was to explore antifungal metabolites targeting fungal cell envelope and to evaluate the control efficacy against anthracnose development in pepper plants. A natural product library comprising 3000 microbial culture extracts was screened via an adenylate kinase (AK)-based cell lysis assay to detect antifungal metabolites targeting the cell envelope of plant-pathogenic fungi. The culture extract of Streptomyces mauvecolor strain BU16 displayed potent AK-releasing activity. Rimocidin and a new rimocidin derivative, BU16, were identified from the extract as active constituents. BU16 is a tetraene macrolide containing a six-membered hemiketal ring with an ethyl group side chain instead of the propyl group in rimocidin. Rimocidin and BU16 showed broad-spectrum antifungal activity against various plant-pathogenic fungi and demonstrated potent control efficacy against anthracnose development in pepper plants. Antifungal metabolites produced by S. mauvecolor strain BU16 were identified to be rimocidin and BU16. The compounds displayed potent control efficacy against pepper anthracnose. Rimocidin and BU16 would be active ingredients of disease control agents disrupting cell envelope of plant-pathogenic fungi. The structure and antifungal activity of rimocidin derivative BU16 is first described in this study. © 2016 The Society for Applied Microbiology.

    Laryngeal cancer is the commonest head and neck cancer seen at the Ear Nose and Throat (ENT) Unit Korle Bu Teaching Hospital. The aim of this study was to determine the number of cases of laryngeal cancer seen at the Korle Bu Teaching Hospital, establish epidemiological parameters of the disease and to outline preventive measures. One hundred and fifteen (115) patients who were managed for laryngeal cancer from 1st January 1998 to 31st December 2003 were studied retrospectively with respect to age, sex, duration of symptoms at presentation, risk factors, symptoms complex, histopathology, stage of tumor, details of treatment offered and follow up. The age range was 17-85 years with a mean of 55.5 years (SD10.7). Majority of the patients (90.4%) were above 40 years. The commonest symptom at presentation was dysphonia. A significant proportion of cases (37.3%) presented with locally advanced disease. The commonest histological type of laryngeal tumour seen was squamous cell carcinoma. The treatment offered consisted of radiotherapy for 83 (79.8%) patients and total laryngectomy with neck dissection when necessary for 17 (16.3%) patients who also had postoperative radiotherapy. Only 58 (69.9%) patients completed radiotherapy treatment and in all 32 (24.3 %) patients did not report for any treatment. Majority of patients failed to report for post treatment follow-up. We conclude that significant number of patients with laryngeal cancer presented with locally advanced disease and dysphonia was the commonest symptom. (au)

  1. Einstein's ``Spooky Action at a Distance'' in the Light of Kant's Transcendental Doctrine of Space and Time

    Science.gov (United States)

    Hacyan, Shahen

    2006-11-01

    Since the famous Einstein-Podolsky-Rosen (EPR) paper, it is clear that there is a serious incompatibility between local realism and quantum mechanics. Einstein believed that a complete quantum theory should be free of what he once called "spooky actions at distance". However, all experiments in quantum optics and atomic physics performed in the last two decades confirm the existence of quantum correlations that seem to contradict local realism. According to Bohr, the apparent contradictions disclose only the inadequacy of our customary concepts for the description of the quantum world. Are space and time such customary concepts? In this presentation, I argue that the Copenhagen interpretation is compatible with Kant's transcendental idealism and that, in particular, EPR type paradoxes are consistent with Kant's transcendental aesthetics, according to which space and time have no objective reality but are pure forms of sensible intuition.

    Standard ambulatory night sleep electroencephalograph (EEG) of 11 long-term practitioners of the Transcendental Meditation (TM) program reporting "higher states of consciousness" during sleep (the experimental group) was compared to that of nine short-term practitioners and 11 non-practitioners. EEG tracings during stages 3 and 4 sleep showed the experimental group to have: 1) theta-alpha activity simultaneously with delta activity and 2) decreased chin electromyograph (EMG) during deep sleep (p = 0.002) compared to short-term practitioners. Spectral analysis fast Fourier transform (FFT) data of the first three cycles showed that: 3) the experimental subjects had significantly greater theta 2 (6-8 Hz)-alpha 1 (8-10 Hz) relative power during stages 3 and 4 than the combined control groups [t(30) = 5.5, p = 0.0000008] with no difference in time in delta; 4) there was a graded difference across groups during stages 3 and 4 in theta 2-alpha 1 power, with experimentals having greater power than short-term practitioners, who in turn had greater power than non-practitioners [t(30) = 5.08, p = 0.00002]; and 5) experimentals also had increased rapid eye movement (REM) density during REM periods compared to short-term practitioners (p = 0.04). Previous studies have found increased theta-alpha EEG activity during reported periods of "transcendental consciousness" during the TM technique. In the Vedic tradition, as described by Maharishi Mahesh Yogi, transcendental consciousness is the first of a sequence of higher states. The maintenance of transcendental consciousness along with deep sleep is said to be a distinctive criterion of further, stabilized higher states of consciousness. The findings of this study are interpreted as physiological support for this model.

  4. Development and Evaluation of the Boston University Osteoarthritis Functional Pain Short Form (BU-OA-FPS).

    2018-04-19

    Pragmatic studies have gained popularity, thus emphasizing the need for patient-reported outcomes (PRO) to be integrated into electronic health records. This study describes the development of a customized short form from the Boston University Osteoarthritis Functional Assessment PRO (BU-OA-PRO) for a specific pragmatic clinical trial. A Functional Pain Short Form was created from an existing item bank of deidentified data in the BU-OA-PRO. Item response theory (IRT) methods were used to select items. Reliability was measured with the Cronbach alpha, then with IRT simulation methods. To examine validity, ceiling and floor effects, correlations between the short-form scores and scores from the BU-OA-PRO and the Western Ontario McMasters University Osteoarthritis Index (WOMAC) Pain and Difficulty subscales, and the area under the curve (AUC) were calculated. A minimum detectable change at 90% confidence (MDC90) was calculated based on a calibration sample. The BU-OA PRO was reduced from 126 items to 10 items to create the BU-OA Functional Pain Short Form (BU-OA-FPS). The Cronbach alpha indicated high internal consistency (0.91), and reliability distribution estimates were 0.96 (uniform) and 0.92 (normal). Low ceiling effects (4.57%), and floor effects (0%) were found. Moderate-to-high correlations between the BU-OA PRO and BU-OA-FPS were found with WOMAC Pain (BU-OA-FPS = 0.67; BU-OA-PRO = 0.64) and Difficulty (BU-OA-FPS = 0.73; BU-OA-PRO = 0.69) subscales. The correlation between the BU-OA-PRO and BU-OA-FPS was 0.94. The AUC ranged from 0.80 to 0.88. The MDC90 was approximately 6 standardized points. The BU-OA-FPS provides reliable and valid measurement of functional pain. Pragmatic studies may consider the BU-OA-FPS for use in electronic health records to capture outcomes.

  5. [An approach to bacteriological taxonomy by application of Immanuel Kant's transcendental dialectics (author's transl)].

    Science.gov (United States)

    Habs, H

    1981-01-01

    After having altered the name of International Committee for Bacteriological Nomenclature in International Committee on Systematic Bacteriology in 1970, the latter will also have to reflect upon the objects of taxonomy. An approach thereto is recognizable in the revision of the International Code of Nomenclature of Bacteria in 1975. Considerations are being made whether a classification of bacteria does justice to the laws of homogenicity, specification and continuity as laid down by Kant in his transcendental dialectic. Most important of all are definition and determination of the taxon species. As far as contents go the latter is not possible from the biological point of view but applicable to its range in application of the regulations of the code. Within the priorities of taxa the species adopts a preferential position because conceptions of applied bacteriology are contained therein. The variety of infra-subspecific subdivisions is taken into consideration; as far as the formae speciales are concerned considerations as made with regard to species apply.

An early sign of ventricular remodeling is increased left ventricular mass (LVM which over time may lead to left ventricular hypertrophy, the strongest predictor of cardiovascular morbidity and mortality, other than advancing age. Methods. 62 (30 TM; 32 CTL African American adolescents (age 16.2±1.3 years with high normal systolic BP were randomly assigned to either 4-month Transcendental Meditation (TM or health education control groups. The echocardiographic-derived measure of LVM index (LVMI = LVM/ht2.7 was measured before and after the 4-month TM study and at 4-month followup. 2D-guided M-mode echocardiography using a Hewlett Packard 5500 echosonograph was used to determine LVMI. Results. The TM group exhibited a greater decrease in LVMI at 4-month followup compared to the CTL group (−2.6 versus +0.3 gm/ht2.7, P<0.04. The TM group exhibited a lesser increase in BMI at 4-month follow-up compared to the CTL group (0.2±1.6 versus 1.1±1.4, P<0.03. Conclusion. These findings indicate that among a group of prehypertensive African American adolescents, 4 months of TM compared to heath education resulted in a significant decrease in LVMI, and these changes were maintained at 4-month follow-up.

    The aim of this thesis was to investigate the acute autonomic effects of the Transcendental Meditation Program (TM) and resolve the conflict arising from discrepant neurochemical and psychophysiological data. Three experimental investigations were performed. The first examined beta 2 -adrenergic receptors (AR's) on peripheral blood lymphocytes, via [I 125 ]iodocyanopindolol binding, in 10 male mediating and 10 age matched non-meditating control subjects, to test the hypothesis that the long-term practice of TM and the TM Sidhi Program (TMSP) reduces end organ sensitivity to adrenergic agonists. The second investigated respiratory sinus arrhythmia (an indirect measure of cardiac Parasympathetic Nervous System tone), and skin resistance (a measure of Sympathetic Nervous System tone) during periods of spontaneous respiratory apneusis, a phenomenon occurring during TM that is known to mark the subjective experience of transcending. The third was within subject investigation of the acute effects of the TMSP on 5-hydroxytryptamine (5-HT) activity. Platelet 5-HT was assayed by high pressure liquid chromatography with electrochemical detection, plasma prolactin (PL) and lutenizing hormone (LH) by radioimmunoassay, tryptophan by spectrofluorimetry, and alpha-1-acid glycoprotein (AGP, a modulator of 5-HT uptake) by radial immunodiffusion assay

    There is a problem associated with contemporary studies of philosophy of mind, which focuses on the identification and convergence of human and machine intelligence. This is the problem of machine emulation of sense. In the present study, analysis of this problem is carried out based on concepts from structural and post-structural approaches that have been almost entirely overlooked by contemporary philosophy of mind. If we refer to the basic definitions of "sign" and "meaning" found in structuralism and post-structuralism, we see a fundamental difference between the capabilities of a machine and the human brain engaged in the processing of a sign. This research will exemplify and provide additional evidence to support distinctions between syntactic and semantic aspects of intelligence, an issue widely discussed by adepts of contemporary philosophy of mind. The research will demonstrate that some aspect of a number of ideas proposed in relation to semantics and semiosis in structuralism and post-structuralism are similar to those we find in contemporary analytical studies related to the theory and philosophy of artificial intelligence. The concluding part of the paper offers an interpretation of the problem of formalization of sense, connected to its metaphysical (transcendental) properties.

  15. Gnostic hermeneutics of Islam, with special emphasis on the transcendental philosophy of Mulla Sadra Shirazi

    2014-01-01

    Full Text Available In all periods of brilliant Gnostic heritage of Islam, much has been written about esoteric meanings and secret depths of the Qur'an and traditions. Numerous representatives of Muslim practical and doctrinal gnosis have extensively interpreted the most sophisticated teachings of sacred religious texts revealing them in the light of their intuitive knowledge of the human's soul path of development, and the highest realities of the metaphysical sphere of existence. In this paper, we first determine the basic historical contexts and terminology of the process of Gnostic hermeneutics of Islam, and then we extensively analyze the most important ontological-anthropological and methodological principles of the process. As the aforementioned rational principles have been elaborated on in an established demonstrative-philosophical language in the school of transcendental philosophy - the most dominant traditional philosophical school of Islam, we will use here primarily the method of detailed analysis of the contents of the most influential works of the renowned founder of the school, Mulla Sadra Shirazi. We show that the esoteric depths of the primordial Qur'anic messages are recognized in the same way that the existence of numerous profound spheres of the entire universe and human beings is established. We will also explain that in the process of hermeneutic discovering of layered secrets of the Qur'an and traditions, Muslim Gnostics do not reject the exoteric meanings of Qur'anic message, but they deepen these meanings, freeing them from unnecessary restrictions of material forms and thus reach the essential mystery of God's speech.

    The attainment of high standards of efficiency and reliability in the practice of nuclear medicine requires an appropriate quality assurance programme. Routine monitoring of nuclear medicine instruments, using test procedures that provide check of the quality and reproducibility of instrument performance, aims at giving the user the confidence in the data collected and in updating the performance of the instrument. Quality control testing schedule for rectilinear scanners include weekly density calibration and monthly performance contrast enhancement and collimator evaluation. Discussion in this work is restricted to collimator evaluation which is required to be performed at the initial stages of installation as acceptance reference. However unlike the density, calibration and contrast enhancement, there is no documented work on this for the M800 Scintikart Scanner - a Hungarian Gamma Muvek system belonging to the Korle Bu Hospital, Accra. Tests of linearity of energy, relative sensitivity and resolution including energy and spatial resolutions were conducted in respect of collimator evaluation. In the linearity test it was ascertained that a nonlinear relationship exists between the centre of the window setting and the energy of the photopeak. The spectrometer was calibrated independently for each radionuclide and the position of Tc-99m obtained at 0.45 MeV on the MeV scale. In addition, the F272a13 Collimator offered a better resolution than the routinely used F272a136 collimator which has the highest sensitivity. (author). 10 refs.; 1 tab.; 10 figs

    Full Text Available Starting with an overview of possible solutions to the problem of social order, the author presents a non-acritical reconstruction of Edmund Husserl's transcendental phenomenology of intersubjectivity as a sympathetic alternative to Habermas's theory of communicative action. By means of a detailed analysis of the concept of empathy (Einfühlung, he shows that Husserl's phenomenology of intersubjectivity offers a triple foundation of the sciences. As a warrant of the objectivity of the world, it grounds the natural sciences; as a presupposition of sociality, it founds the social sciences; as mediated by culture, it grounds the social sciences as human sciences.

    TCS is a widely used haplotype network reconstruction software, but lacks the capability of overlapping genetic with geographic structure, which is often a first step in phylogeographic analysis. tcsBU is a web-based program that extends the capabilities of TCS, by implementing haplotype classification into an arbitrary user-defined scheme, which is displayed as pie-chart like graphs embedded into the network. Taking advantage of modern graphic libraries, tcsBU also improves the speed at which the final network layout is reached. Networks can be saved as a Scalable Vector Graphics format. tcsBU is available on-line at http://cibio.up.pt/software/tcsBU/.

The bulky P(2)P(3)(tBu) (1) and P(3)P(3)(tBu) (3) ligands are the most sterically encumbered PP(3)-type ligands so far synthesized, and in all cases, only three phosphorus donors are able to bind to the metal center. Complexes RuCl(2)(PhP(2)P(2)(tBu)) (5) and RuCl(2)(P(3)P(3)(tBu)) (6) were characterized by crystallography. Low temperature solution and solid state (31)P{(1)H} NMR were used to demonstrate that the structure of RuCl(2)(P(2)P(3)(tBu)) (4) is probably analogous to that of RuCl(2)(PhP(2)P(2)(tBu)) (5) which had been structurally characterized.

    A thermophilic bacterial strain, Acinetobacter calcoaceticus BU03, with a biosurfactant-producing capability, was isolated from petroleum-contaminated soil with an improved procedure which employed the solubilization of polycyclic aromatic hydrocarbons (PAHs), i.e. naphthalene in agar plate, as a selection criterion. Crude biosurfactant was recovered from the culture of BU03 by extraction with n-hexane, and its properties were investigated. Biosurfactants from A. calcoaceticus BU03 constitute a thermo-stable mixture, composed of different agents with surface activities. At their critical micelle concentration (CMC) of 152.4 mg L(-1), the crude biosurfactants produced from A. calcoaceticus BU03 decreased the air-water surface tension to 38.4 mN m(-1). In thermophilic conditions, the emulsifying activity is 2.8 times that of Tween 80. The effects of the biosurfactants produced by A. calcoaceticus on the solubility and biodegradation of PAHs were investigated in batch systems. Biosurfactants produced by A. calcoaceticus BU03 at 25 times their CMC significantly increased the apparent aqueous solubility of phenanthrene (PHE), pyrene (PYR) and benzo(a)pyrene (B[a]P) to 54.3, 6.33 and 2.08 mg L(-1), respectively. In aqueous system, the biosurfactants at concentrations of 0.5 CMC and 1 CMC slightly enhanced the biodegradation of PHE by a consortium of PAH-degrading microrganisms. Results indicate that biosurfactants from A. calcoaceticus BU03 have potential to enhance the removal of PAHs from contaminated sites.

  3. ECOLOGIA NA ÓTICA DO NIILISMO: POR UMA ECOLOGIA ABERTA AO TRANSCENDENTE

    Directory of Open Access Journals (Sweden)

    Clodovis Boff

    2010-01-01

    Full Text Available Aborda-se aqui a questão ecológica numa perspectiva pouco comum: a do niilismo moderno. Este é aqui entendido, em geral, como vida sem sentido e, em particular, como falta de um sentido último e transcendente para a vida. A falta de sentido estaria na raiz da falta de respeito e de amor à natureza. Pois, se a vida humana não tem sentido, como o teria a natureza? A crise ecológica seria, pois, um aspecto de uma crise mais ampla e mais profunda: a crise do sentido. Mas de onde provém a crise de sentido? Provém, no fundo, de uma visão secularista do mundo. Tal visão, radicalmente antropocentrista e prescindindo de Deus, acaba entregando o mundo à vontade de potência do ser humano, inclusive na forma de niilismo ativo ou destrutivo. A “ecologia profunda”, enquanto se quer “biocêntrica” ou “ecocêntrica”, não é uma verdadeira alternativa, por manter-se ainda presa, como o antropocentrismo, a uma perspectiva fundamentalmente imanentista do mundo. A verdadeira saída se dá “por cima”: consiste em reconhecer a “criaturalidade” das coisas, enquanto dependentes do Criador e possuindo, por isso mesmo, um valor próprio, que o ser humano é chamado a respeitar e de que deve dar conta. ABSTRACT: This article treats the question of ecology in a not so common perspective: that of modern nihilism. This perspective is understood, in general, as life without meaning, and in particular, as a lack of an ultimate and transcendent meaning for life. The lack of meaning would be the root of the lack of respect and love for nature. Therefore, if human life does not have meaning, how would nature have meaning? The ecological crisis would be, therefore, an aspect of a larger and deeper crisis: the crisis of meaning. But where does the crisis of meaning come from? It comes from, in depth, a secularist vision of the world. Such a vision, radically anthropocentrist and dispensing with God, ends up delivering the world to the potent will

    2001-07-01

    This study tested the prediction that reading Vedic Sanskrit texts, without knowledge of their meaning, produces a distinct physiological state. We measured EEG, breath rate, heart rate, and skin conductance during: (1) 15-min Transcendental Meditation (TM) practice; (2) 15-min reading verses of the Bhagavad Gita in Sanskrit; and (3) 15-min reading the same verses translated in German, Spanish, or French. The two reading conditions were randomly counterbalanced, and subjects filled out experience forms between each block to reduce carryover effects. Skin conductance levels significantly decreased during both reading Sanskrit and TM practice, and increased slightly during reading a modern language. Alpha power and coherence were significantly higher when reading Sanskrit and during TM practice, compared to reading modern languages. Similar physiological patterns when reading Sanskrit and during practice of the TM technique suggests that the state gained during TM practice may be integrated with active mental processes by reading Sanskrit.

    Full Text Available Este artigo reconstrói os momentos principais dos trabalhos de Dieter Henrich sobre a filosofia teórica de Immanuel Kant. Henrich procura esclarecer e recuperar os fundamentos da teoria do conhecimento de Kant, dos quais seus seguidores teriam se distanciado, a partir da análise da dedução transcendental das categorias. De início, Henrich investiga a estrutura da prova na dedução, comparando a primeira e a segunda edição da Crítica da Razão Pura. Em seguida, Henrich investiga no argumento kantiano a relação entre o princípio de identidade da consciência de si, por um lado, e objetividade, por outro. Por fim, estendendo a comparação à Crítica da Razão Prática, Henrich elucida o programa e a metodologia na dedução, mostrando como o "fato" legitimador se torna o elemento fundamental.This article reconstructs the principal moments of Dieter Henrich's work on Immanuel Kant's theoretical philosophy.

Firstly, Henrich investigates the proof structure in the deduction, comparing the first and the second edition of the Critique of Pure Reason. Secondly, he investigates, inside Kantian argument, the relationship between the identity principle of self-consciousness and objectivity. Finally, extending the comparison to the Critique of Practical Reason, Henrich elucidates the program and methodology of deduction, showing how the legitimating fact becomes the fundamental element.

    Full Text Available The economic fluctuations in Indonesia apparently do not influence the food and beverage business. This business still goes well, because people need food. Food is a primary need that must be met and is not influenced by economic conditions in Indonesia. One food and beverage business is Warung Bu Kris, in Surabaya. This restaurant offers various choices. Most of the food served is pressed (penyet and blended with fresh chile sauce (sambal. Many people like this food and usually choose this kind of food as their first choice. The restaurant is usually full of people. Although there are not any seats, customers are willing to wait in order to eat their favorite food. The sample was chosen using non-random sampling. Data were collected in two steps, first to determine the favorite menu of Warung Bu Kris. The second step was to examine the relationship between customer satisfaction and loyalty, then to examine the relationship between both customer satisfaction and loyalty with sales at Warung Bu Kris. The weighted mean formula is used to analyze data in the beginning survey. For the second step, correlation is used. The results show that chicken penyet is the favorite dish at Warung Bu Kris. There is an association between satisfaction and loyalty and also between both customer satisfaction and loyalty with sales. These results suggest that Warung Bu Kris should improve product quality and service in order to maintain customer loyalty. The results can also give further information to other entrepreneurs who will open this type of business in the future.

    Full Text Available Parece urgente a investigação dos processos de coesão nos Estudos de execução transcendental de Franz Liszt: a emergência de um todo unificado é sugerida já no plano tonal que os coordena. O exame de outros aspectos que pudessem garantir unidade - vinculados aos materiais específicos das composições - constitui o foco do presente trabalho. Seu recorte é o subconjunto formado pelas últimas sete peças do grupo, justificado pelo fato de elas demonstrarem uma afinidade particular, o salto de sexta ascendente antecedido por diferentes formas de ênfase. O fundamento teórico adotado é uma adaptação do conceito de subtematismo de Dahlhaus, que nutre o procedimento metodológico: a abordagem analítica. Os resultados mostram conexões baseadas não apenas em fenômenos harmônicos, mas também na recorrência de materiais flexíveis que sofrem transformações. Com isso, confirma-se a coesão dos recortes e a pertinência dos processos de integração no volume de Liszt.It seems to be urgent the investigation upon the cohesive processes in the Transcendental studies by Franz Liszt: the emergence of a unified whole is already suggested in the tonal plan that coordinates them. The examination of other aspects that could guarantee unity - related to specific materials of the compositions - is this text's main concern. Its focus is the subset formed by the last seven pieces of the group, and that is justified by the fact that they show a particular affiliation, the ascending leap of sixth preceded by different forms of emphasis. The theoretical basis adopted is an adaptation of Dahlhaus' concept of subthematicism, which supports the methodological procedure: the analytical approach. The results show connections based not only on harmonic phenomena, but also on the recurrence of flexible materials that are object of transformations. Hence, it is possible to substantiate the cohesion of the selected pieces and the relevance of the

    Full Text Available Abstract Background α-Conotoxins have exciting therapeutic potential based on their high selectivity and affinity for nicotinic acetylcholine receptors. The spacing between the cysteine residues in α-conotoxins is variable, leading to the classification of sub-families. BuIA is the only α-conotoxin containing a 4/4 cysteine spacing and thus it is of significant interest to examine the structure of this conotoxin. Results In the current study we show the native globular disulfide connectivity of BuIA displays multiple conformations in solution whereas the non-native ribbon isomer has a single well-defined conformation. Despite having multiple conformations in solution the globular form of BuIA displays activity at the nicotinic acetylcholine receptor, contrasting with the lack of activity of the structurally well-defined ribbon isomer. Conclusion These findings are opposite to the general trends observed for α-conotoxins where the native isomers have well-defined structures and the ribbon isomers are generally disordered. This study thus highlights the influence of the disulfide connectivity of BuIA on the dynamics of the three-dimensional structure.

    The pathogenesis and progression of cardiovascular diseases are thought to be exacerbated by stress. Basic research indicates that the Transcendental Meditation® technique produces acute and longitudinal reductions in sympathetic tone and stress reactivity. In adolescents at risk for hypertension, the technique has been found to reduce resting and ambulatory blood pressure, left ventricular mass, cardiovascular reactivity, and to improve school behavior. Research on adults with mild or moderate essential hypertension has reported decreased blood pressure and reduced use of anti-hypertensive medication. The technique has also been reported to decrease symptoms of angina pectoris and carotid atherosclerosis, to reduce cardiovascular risk factors, including alcohol and tobacco use, to markedly reduce medical care utilization for cardiovascular diseases, and to significantly decrease cardiovascular and all-cause morbidity and mortality. These findings have important implications for inclusion of the Transcendental Meditation program in efforts to prevent and treat cardiovascular diseases and their clinical consequences. ®Transcendental Meditation and TM are trademarks registered in the US.

  19. Transcendental Trinitarian: James Marsh, the Free Will Problem, and the American Intellectual Context of Coleridge’s Aids to Reflection

    Directory of Open Access Journals (Sweden)

    Jonathan Koefoed

    2017-08-01

    Full Text Available Historians of American religion and Transcendentalism have long known of James Marsh as a catalyst for the Concord Transcendentalist movement. The standard narrative suggests that the Congregationalist Marsh naively imported Samuel Taylor Coleridge's Aids to Reflection (Am. ed. 1829 hoping to revivify orthodoxy in America. By providing a “Preliminary Essay” to explain Coleridge’s abstruse theology, Marsh injected Coleridge’s hijacked Kantian epistemology—with its distinction between Reason and Understanding—into American discourse. This epistemology inspired Transcendentalists such as Ralph Waldo Emerson and Bronson Alcott, and it helped spark the Transcendentalists’ largely post-Christian religious convictions. This article provides a re-evaluation of Marsh’s philosophical theology by attending to the precise historical moment that Marsh chose to publish the Aids to Reflection and his “Preliminary Essay.” By the late 1820s, the philosophical problem of free will lurked in American religious discourse—Unitarian as well as Trinitarian—and Marsh sought to exploit the problem as a way to explain how aspects of Trinitarian Christianity might be rational and yet unexplainable. Attending carefully to the numerous philosophical and religious discourses of the moment—including Unitarianism, Trinitarianism, Kant, Coleridge, and Scottish Common Sense—and providing close readings of the historical philosophers Marsh engaged, this article shows how James Marsh laid the epistemological groundwork for a new romanticized Christianity that was distinct from the Concord Transcendentalists, but nonetheless part of its historical lineage.

    The amount of studies showing different benefits of practicing meditation is growing. EEG brainwave patterns objectively reflect both the cognitive processes and objects of meditation. This study aimed to examine the effects of transcendental meditation (TM) practice on baseline EEG brainwave patterns (outside of meditation) and to examine weather TM reduces state and trait anxiety. Standard EEG recordings were conducted on volunteer participants (N=12), all students or younger employed people, before and after a three-month meditation training. Artifact-free 100-second epochs were selected and analyzed by Fast Fourier Transformation (FFT) analysis. Endlers Multidimensional Anxiety Scales (EMAS) were used to assess anxiety levels. Power (μV(2)) and coherence levels were compared in the alpha, beta, theta and delta frequency band. Changes in EEG patterns after meditation practice were found mostly in the theta band. An interaction effect was found on the left hemisphere (pmeditation practice. Most of the changes were found in the occipital and temporal areas, less in the central and frontal areas. State anxiety decreased after TM practice. Findings suggest TM practice could be helpful in treating different kinds of disorders, especially anxiety disorders.

  1. Higher theta and alpha1 coherence when listening to Vedic recitation compared to coherence during Transcendental Meditation practice.

    This study compared subjective experiences and EEG patterns in 37 subjects when listening to live Vedic recitation and when practicing Transcendental Meditation (TM). Content analysis of experiences when listening to Vedic recitation yielded three higher-order code. Experiences during Vedic recitation were: (1) deeper than during TM practice; (2) experienced as an inner process; and (3) characterized by lively silence. EEG patterns support these higher-order codes. Theta2 and alpha1 frontal, parietal, and frontal-parietal coherence were significantly higher when listening to Vedic recitation, than during TM practice. Theta2 coherence is seen when attending to internal mental processes. Higher theta2 coherence supports subjects' descriptions that the Vedic recitations were "not external sounds but internal vibrations." Alpha1 coherence is reported during pure consciousness experiences during TM practice. Higher alpha1 coherence supports subjects' descriptions that they "experienced a depth of experience, rarely experienced even during deep TM practice." These data support the utility of listening to Vedic recitation to culture deep inner experiences. Copyright © 2017 Elsevier Inc. All rights reserved.

  2. Intentionality and Presence: On the Intrinsic Of-ness of Consciousness from a Transcendental-Phenomenological Perspective.

    Science.gov (United States)

    Fasching, Wolfgang

    This paper discusses the nature of consciousness' intrinsic intentionality from a transcendental-phenomenological viewpoint. In recent philosophy of mind the essentially intentional character of consciousness has become obscured because the latter is predominantly understood in terms of "qualia" or the "what-it-is-like-ness" of mental states and it is hard to see why such subjective "feels", of all things, could bestow states with objective reference. As the paper attempts to demonstrate, this is an inadequate understanding of consciousness, which should instead be defined in terms of presence. Consciousness essentially takes place as presence-of, i.e., consists in something coming to appearance. This presence-of is not only a fundamental, irreducible phenomenon, but also in a radical sense un-naturalisable. Naturalism only knows "nature", as the world of objects, and the question of intentionality then seems to be how certain inner-worldly objects can be "representations" of other inner-worldly objects. In fact, no object is ever intrinsically "about" anything. This is exclusively the nature of subjectivity qua consciousness, which is not an object alongside other objects but rather exists as the manifestation of objects.

    Butanol-extracted water-soluble adjuvant (Bu-WSA) obtained from Bacterionema matruchotii was cultured with peripheral blood mononuclear cells (PBM) in the presence of sub- and/or supra-optimal mitogenic concentrations of concanavalin A (Con A). The addition of Bu-WSA resulted in increased tritiated thymidine incorporation above that produced by Con A alone. Bu-WSA by itself is not mitogenic for PBM and in fact produced a decrease in thymidine uptake compared to the control. We investigated the response of subpopulation(s) of PBM to Bu-WSA, Con A and a mixture of Bu-WSA and Con A. Separation of PBM into purified T cells, B cells and macrophages showed that cell-cell cooperation of T cells with B cells or macrophages is necessary for the observed synergistic effect of Bu-WSA with Con A. A marked increase in thymidine incorporation by the mixture of T and B cell populations occurred, while only a small amount of thymidine was incorporated when the B cell population was absent. Mitomycin treatment revealed that the response could be ascribed to the T-cell response with a B-cell helper effect. Moreover, Con A and Bu-WSA appeared to act on the same T cell population. This model may provide unique information about the activation of human peripheral blood T cells compared with the activation of these cells by other mitogens. © owned by Center for Academic Publications Japan (Publisher).

    Crystal structures of BurrH and the BurrH–DNA complex are reported. DNA editing offers new possibilities in synthetic biology and biomedicine for modulation or modification of cellular functions to organisms. However, inaccuracy in this process may lead to genome damage. To address this important problem, a strategy allowing specific gene modification has been achieved through the addition, removal or exchange of DNA sequences using customized proteins and the endogenous DNA-repair machinery. Therefore, the engineering of specific protein–DNA interactions in protein scaffolds is key to providing ‘toolkits’ for precise genome modification or regulation of gene expression. In a search for putative DNA-binding domains, BurrH, a protein that recognizes a 19 bp DNA target, was identified. Here, its apo and DNA-bound crystal structures are reported, revealing a central region containing 19 repeats of a helix–loop–helix modular domain (BurrH domain; BuD), which identifies the DNA target by a single residue-to-nucleotide code, thus facilitating its redesign for gene targeting. New DNA-binding specificities have been engineered in this template, showing that BuD-derived nucleases (BuDNs) induce high levels of gene targeting in a locus of the human haemoglobin β (HBB) gene close to mutations responsible for sickle-cell anaemia. Hence, the unique combination of high efficiency and specificity of the BuD arrays can push forward diverse genome-modification approaches for cell or organism redesign, opening new avenues for gene editing.

    Buruli ulcer (BU) disease, a skin condition caused by Mycobacterium ulcerans (M. ulcerans) is endemic in remote rural areas. Disease diagnosis on clinical basis alone can be misleading, requiring definitive diagnosis based on laboratory tests. Resource constraints in BU endemic areas make microscopy for the detection of acid fast bacilli (AFB) an important and useful method. It is rapid, user-friendly, convenient and cheap. Despite its usefulness, its performance is relatively low. This study investigated modifications of the current method aimed at improving its performance. Forty (IS) 2404 polymerase chain reactions (PCR) positive BU samples were processed by eight physical (centrifugation and overnight sedimentation) and chemical (phenol ammonium sulphate and sodium hypochlorite) modifications of the current direct method. Assessments were based on standard AFB evaluation coupled with in house criteria; positivity (P), clarity and contrast (C) release of bacilli from specimen (R). Overall AFB positivity rate was 64% (409/640). Each protocol had 80 smears. The percentage positivity (P) for the conventional method was 58% (46/80) smears. The highest positivity rate of 57/80 (%) was by protocol 7 (5% phenol in 4% ammonium sulphate (PhAS) and concentrated by overnight gravitational sedimentation). The least positivity rate at 35% (28/80) was by protocol 1 (smears from direct application of swab tips). The differences in performance between the two chemical tested; 5% phenol in 4% ammonium sulphate (PhAS) and 3.5% NaHOCl was significant (p0.05). This study concluded that BU samples treated with a solution of 5% phenol in 4% ammonium sulphate and concentrated by either centrifugation or overnight sedimentation is useful for maximizing AFB detection by bright field microscopy. This can be useful in rural health facilities with resource constraints. Copyright © 2015 Asian-African Society for Mycobacteriology. Published by Elsevier Ltd. All rights reserved.

    The U-2bu subsidence crater, Corrective Action Unit 109, will be closed in accordance with the Resource Conservation and Recovery Act, the Nevada Division of Environmental Protection operational permit, and the Federal Facility Agreement and Consent Order. The U-2bu subsidence crater is located in Area 2 of the Nevada Test Site. It was created in 1971 by an underground nuclear test with the name Miniata. The crater has a diameter of 288 meters (944 feet) and an approximate depth of 35 meters (115 feet). Based on the results of the analyses reported in the site characterization report, the only constituents of concern in the U-2bu subsidence crater include leachable lead and total petroleum hydrocarbons. Closure activities will include the excavation and disposal of impacted soil from the top of the crater. Upon completion of excavation, verification samples will be collected to show that the leachable lead has been removed to concentrations below the regulatory action level. After sample results show that the lead has been removed, the excavated area will be backfilled and a soil flood diversion berm will be constructed as a best management practice. An independent registered professional engineer will certify the site was closed following the approved Closure Plan. Post-closure care is not warranted for this site because closure activities will involve removal of the Resource Conservation and Recovery Act constituents of concern

    National-level demonstration projects and real-world studies continue to inform health care transformation efforts and catalyze implementation of value-based service delivery and payment models, though evidence generation and diffusion of learnings often occurs at a relatively slow pace. Rapid-cycle learning models, however, can help individual organizations to more quickly adapt health care innovations to meet the challenges and demands of a rapidly changing health care landscape. Integrated delivery and financing systems (IDFSs) offer a unique platform for rapid-cycle learning and innovation. Since both the provider and payer benefit from delivering care that enhances the patient experience, improves quality, and reduces cost, incentives are aligned to experiment with value-based models, enhance learning about what works and why, and contribute to solutions that can accelerate transformation. In this article, we describe how the UPMC Insurance Services Division, as part of a large IDFS, uses its Business, Innovation, Learning, and Dissemination (BuILD) model to prioritize, design, test, and refine health care innovations and accelerate learning. We provide examples of how the BuILD model offers an approach for quickly assessing the impact and value of health care transformation efforts. Lessons learned through the BuILD process will offer insights and guidance for a wide range of stakeholders whether an IDFS or independent payer-provider collaborators. Copyright © 2018 Elsevier Inc.

    The stability of the ionic liquid [MeBu 3 N][Tf 2 N], dry or after contact with water (where [MeBu 3 N] + is the methyl-tributyl-ammonium cation and [Tf 2 N] - is the bistriflimide anion), was studied under 137 Cs gamma irradiation in argon and in air. In a quantitative study with an absorbed dose of 2 MGy this ionic liquid was highly stable regardless of the radiolysis conditions. The radiolytic disappearance yields determined by ESI-MS were -0.38 and -0.25 μmol*J -1 for the cation and anion, respectively. ESI-MS, NMR, and liquid chromatography coupled with ESI-MS identified a large number of degradation products in very small quantities for the same dose. The cation radicals were formed by the loss of a Bu . group, the Me . group, or two H . atoms to form a double bond with the butyl chain. Radiolysis of the anion produced mainly F . and CF 3 . radicals. The anion radicals recombined with the cation to form a wide range of secondary degradation products regardless of the radiolysis conditions. (authors)

  13. RCRA Part A permit characterization plan for the U-2bu subsidence crater. Revision 1

    International Nuclear Information System (INIS)

    1998-04-01

    This plan presents the characterization strategy for Corrective Action Unit (CAU) 109, U-2bu Subsidence Crater (referred to as U-2bu) in Area 2 at the Nevada Test Site (NTS). The objective of the planned activities is to obtain sufficient characterization data for the crater soils and observed wastes under the conditions of the current Resource Conservation and Recovery Act (RCRA) Part A permit. The scope of the characterization plan includes collecting surface and subsurface soil samples with hand augers and for the purpose of site characterization. The sampling strategy is to characterize the study area soils and look for RCRA constituents. Observable waste soils and surrounding crater soils will be analyzed and evaluated according to RCRA closure criteria. Because of the status of the crater a RCRA Part A permit site, acquired radionuclide analyses will only be evaluated in regards to the health and safety of site workers and the disposition of wastes generated during site characterization. The U-2bu Subsidence Crater was created in 1971 by a Lawrence Livermore National Laboratory underground nuclear test, event name Miniata, and was used as a land-disposal unit for radioactive and hazardous waste from 1973 to 1988

ESI-MS, NMR, and liquid chromatography coupled with ESI-MS identified a large number of degradation products in very small quantities for the same dose. The cation radicals were formed by the loss of a Bu-radical group, the Me-radical group, or two H-radical atoms to form a double bond with the butyl chain. Radiolysis of the anion produced mainly F-radical and CF 3 -radicals. The anion radicals recombined with the cation to form a wide range of secondary degradation products regardless of the radiolysis conditions. (authors)

    The U-2bu subsidence crater, Corrective Action Unit 109, will be closed in accordance with the Resource Conservation and Recovery Act, the Nevada Division of Environmental Protection operational permit, and the Federal Facility Agreement and Consent Order. The U-2bu subsidence crater is located in Area 2 of the Nevada Test Site. It was created in 1971 by an underground nuclear test with the name Miniata. The crater has a diameter of 288 meters (944 feet) and an approximate depth of 35 meters (115 feet). Based on the results of the analyses reported in the site characterization report, the only constituents of concern in the U-2bu subsidence crater include leachable lead and total petroleum hydrocarbons. Closure activities will include the excavation and disposal of impacted soil from the top of the crater. Upon completion of excavation, verification samples will be collected to show that the leachable lead has been removed to concentrations below the regulatory action level. After sample results show that the lead has been removed, the excavated area will be backfilled and a soil flood diversion berm will be constructed as a best management practice. An independent registered professional engineer will certify the site was closed following the approved Closure Plan. Post-closure care is not warranted for this site because closure activities will involve removal of the Resource Conservation and Recovery Act constituents of concern.

  16. Detailed structural characterization of the grafting of [Ta(=CHtBu)(CH2tBu)3] and [Cp*TaMe4] on silica partially dehydroxylated at 700 C and the activity of the grafted complexes toward alkane metathesis

    The reaction of [Ta({double_bond}CHtBu)(CH{sub 2}tBu){sub 3}] or [Cp*Ta(CH{sub 3}){sub 4}] with a silica partially dehydroxylated at 700 C gives the corresponding monosiloxy surface complexes [({triple_bond}SiO)Ta({double_bond}CHtBu)(CH{sub 2}tBu){sub 2}] and [({triple_bond}SiO)Ta(CH{sub 3}){sub 3}Cp*] by eliminating a {sigma}-bonded ligand as the corresponding alkane (H-CH{sub 2}tBu or H-CH{sub 3}). EXAFS data show that an adjacent siloxane bridge of the surface plays the role of an extra surface ligand, which most likely stabilizes these complexes as in [({triple_bond}SiO)Ta({double_bond}CHtBu)(CH{sub 2}tBu){sub 2}({triple_bond}SiOSi{triple_bond})] (1a') and [({triple_bond}SiO)Ta(CH{sub 3}){sub 3}Cp*({triple_bond}SiOSi{triple_bond})] (2a'). In the case of [({triple_bond}SiO)Ta({double_bond}CHtBu)(CH{sub 2}tBu){sub 2}({triple_bond}SiOSi{triple_bond})], the structure is further stabilized by an additional interaction: a C-H agostic bond as evidenced by the small J coupling constant for the carbenic C-H (H{sub C-H} = 80 Hz), which was measured by J-resolved 2D solid-state NMR spectroscopy. The product selectivity in propane metathesis in the presence of [({triple_bond}SiO)Ta({double_bond}CHtBu)-(CH{sub 2}tBu){sub 2}({triple_bond}SiOSi{triple_bond})] (1a') as a catalyst precursor and the inactivity of the surface complex [({triple_bond}SiO)Ta-(CH{sub 3}){sub 3}Cp*({triple_bond}SiOSi{triple_bond})] (2a') show that the active site is required to be highly electrophilic and probably involves a metallacyclobutane intermediate.

  19. Antipsychotic-like effect of the muscarinic acetylcholine receptor agonist BuTAC in non-human primates.

    Directory of Open Access Journals (Sweden)

    Maibritt B Andersen

    Full Text Available Cholinergic, muscarinic receptor agonists exhibit functional dopamine antagonism and muscarinic receptors have been suggested as possible future targets for the treatment of schizophrenia and drug abuse. The muscarinic ligand (5R,6R-6-(3-butylthio-1,2,5-thiadiazol-4-yl-1-azabicyclo[3.2.1]octane (BuTAC exhibits high affinity for muscarinic receptors with no or substantially less affinity for a large number of other receptors and binding sites, including the dopamine receptors and the dopamine transporter. In the present study, we wanted to examine the possible antipsychotic-like effects of BuTAC in primates. To this end, we investigated the effects of BuTAC on d-amphetamine-induced behaviour in antipsychotic-naive Cebus paella monkeys. Possible adverse events of BuTAC, were evaluated in the same monkeys as well as in monkeys sensitized to antipsychotic-induced extrapyramidal side effects. The present data suggests that, the muscarinic receptor ligand BuTAC exhibits antipsychotic-like behaviour in primates. The behavioural data of BuTAC as well as the new biochemical data further substantiate the rationale for the use of muscarinic M1/M2/M4-preferring receptor agonists as novel pharmacological tools in the treatment of schizophrenia.

The U-2bu subsidence crater is located in Area 2 of the Nevada Test Site. It was created in 1971 by an underground nuclear test with the name Miniata. The crater has a diameter of 288 meters (944 feet) and an approximate depth of 35 meters (115 feet). The subsidence crater was used as a land disposal unit for radioactive and hazardous waste from 1973 to 1988. Site disposal history is supported by memorandums, letters, and personnel who worked at the Nevada Test Site at the time of active disposal. Closure activities will include the excavation and disposal of impacted soil form the tip of the crater. Upon completion of excavation, verification samples will be collected to show that lead has been removed to concentrations be low regulatory action level. The area will then be backfilled and a soil flood diversion berm will be constructed, and certified by an independent professional engineer as to having followed the approved Closure Plan.

    Full Text Available Cotton leaf curl Burewala virus (CLCuBuV, belonging to the genus Begomovirus, possesses single-stranded monopartite DNA genome. The bidirectional promoters representing Rep and coat protein (CP genes of CLCuBuV were characterized and their efficacy was assayed. Rep and CP promoters of CLCuBuV and 35S promoter of Cauliflower mosaic virus (CaMV were fused with β-glucuronidase (GUS and green fluorescent protein (GFP reporter genes. GUS activity in individual plant cells driven by Rep, CP and 35S promoters was estimated using real-time PCR and fluorometric GUS assay. Histochemical staining of GUS in transformed tobacco (Nicotiana tabacum cv. Xanthi leaves showed highest expression driven by Rep promoter followed by 35S promoter and CP promoter. The expression level of GUS driven by Rep promoter in transformed tobacco plants was shown to be two to four-fold higher than that of 35S promoter, while the expression by CP promoter was slightly lower. Further, the expression of GFP was monitored in agroinfiltrated leaves of N. benthamiana, N. tabacum and cotton (Gossypium hirsutum plants using confocal laser scanning microscopy. Rep promoter showed strong consistent transient expression in tobacco and cotton leaves as compared to 35S promoter. The strong constitutive CLCuBuV Rep promoter developed in this study could be very useful for high level expression of transgenes in a wide variety of plant cells.

    Phenylethanethiol protected nanomolecules such as Au 25 , Au 38 , and Au 144 are widely studied by a broad range of scientists in the community, owing primarily to the availability of simple synthetic protocols. However, synthetic methods are not available for other ligands, such as aromatic thiol and bulky ligands, impeding progress. Here we report the facile synthesis of three distinct nanomolecules, Au 38 (SCH 2 CH 2 Ph) 24 , Au 36 (SPh-tBu) 24 , and Au 30 (S-tBu) 18 , exclusively, starting from a common Au n (glutathione) m (where n and m are number of gold atoms and glutathiolate ligands) starting material upon reaction with HSCH 2 CH 2 Ph, HSPh-tBu, and HStBu, respectively. The systematic synthetic approach involves two steps: (i) synthesis of kinetically controlled Au n (glutathione) m crude nanocluster mixture with 1:4 gold to thiol molar ratio and (ii) thermochemical treatment of the purified nanocluster mixture with excess thiols to obtain thermodynamically stable nanomolecules. Thermochemical reactions with physicochemically different ligands formed highly monodispersed, exclusively three different core-size nanomolecules, suggesting a ligand induced core-size conversion and structural transformation. The purpose of this work is to make available a facile and simple synthetic method for the preparation of Au 38 (SCH 2 CH 2 Ph) 24 , Au 36 (SPh-tBu) 24 , and Au 30 (S-tBu) 18 , to nonspecialists and the broader scientific community. The central idea of simple synthetic method was demonstrated with other ligand systems such as cyclopentanethiol (HSC 5 H 9 ), cyclohexanethiol(HSC 6 H 11 ), para-methylbenzenethiol(pMBT), 1-pentanethiol(HSC 5 H 11 ), 1-hexanethiol(HSC 6 H 13 ), where Au 36 (SC 5 H 9 ) 24 , Au 36 (SC 6 H 11 ) 24 , Au 36 (pMBT) 24 , Au 38 (SC 5 H 11 ) 24 , and Au 38 (SC 6 H 13 ) 24 were obtained, respectively.

    Intravenous BU divided four times daily (q6 h) has been shown to be safe and effective in pediatric allo-SCT recipients. Though less frequent dosing is desirable, pharmacokinetic (PK) data on twice daily (q12 h) i.v. BU administration in pediatric allo-SCT recipients is limited. We prospectively examined the PK results in a cohort of pediatric allo-SCT recipients receiving i.v. BU q12 h as part of conditioning before allo-SCT. BU levels were obtained after the first dose of conditioning. PK parameter analysis (n=49) yielded the following 95% confidence intervals (CI₉₅): weight-normalized volume of distribution: 0.65-0.73 L/kg; t(1/2): 122-147 min; weight-normalized clearance (CL(n)): 3.4-4.3 mL/min/kg; and area under the curve: 1835-2180 mmol × min/L. From these results, a steady state concentration was calculated with CI₉₅ between 628-746 ng/mL. Comparison between recipients ≤4 vs >4 years old revealed significant differences in t(1/2) (mean: 115 vs 146 min, P=0.008) and CL(n) (mean: 4.4 vs 3.5 mL/min/kg, P=0.038). Intravenous BU q12 h had a comparable PK to i.v. BU q6 h PK seen in the literature, and in pediatric allo-SCT recipients, is a feasible, attractive alternative to i.v. q6h dosing.

    The radiological protection assessment based on the shielding of the Co-60 Radiotherapy facility at the Korle Bu Teaching Hospital after the source replacement has been carried out. The results indicate that the concrete biological shield is adequate to attenuate the gamma photons from the new 222 TBq Co-60 source in use. The dose rates at critical locations of the public access area are within the recommended dose rate limit of O.5J..1Sv/h and 7.5J..1Sv/h for public and staff respectively. Thus the shielding has not deteriorated and still provides adequate protection for members of the public and the operating staff (au).

    A practical and scalable nickel-catalyzed allylic stannylation of allyl acetates with Bu3 SnOMe is described. A variety of acyclic and cyclic allyl acetates, even with base-sensitive moieties, undergoes the stannylation by using NiBr2 /4,4'-di-tert-butylbipyridine (dtbpy)/Mn catalyst system to afford highly functionalized allyl stannanes with excellent regioselectivity and yields. Furthermore, the scope of protocol is also extended by the reaction of propargyl acetates, giving rise to propargyl or allenyl stannanes. Additionally, a unique diastereoselectivity using the nickel catalyst different from the palladium was demonstrated for the stannylation of cyclic allyl acetates. In the reaction, inexpensive and stable nickel complexes, abundant reductant (Mn), and atom-economical stannyl source were used. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    Anionic polymerization of methyl methacrylate (MMA), n-butyl methacrylate (nBMA) and glycidyl methacrylate (GMA) initiated by nBuCu(NCy2)Li (1) in tetrahydrofuran (THF) at -50℃ to -10℃ was investigated. It was found that the polymerization of MMA and nBMA initiated by 1 proceeded quantitatively in THF to afford PMMA and PBMA with polydispersity index 1.15-1.30 and nearly 100% initiator efficiencies at -10℃. The molecular weights increased linearly with the ratio of [monomer]/[1]. However, a post-polymerization experiment carried out on this system revealed a double polymer peak by GPC when fresh monomer was added after an interval of 10 rain. Polymerization of styrene could be initiated by 1, but the initiator efficiency was low.

    The introduction of bulky residue(s) in linear enkephalin-related hexapeptides represents a new approach in the design of selective probes for {delta}-opioid receptors, displaying the appropriate criteria to investigate biological and pharmacological properties of the assumed binding site ({delta}) of endogenous enkephalins. The selectivities and high affinities of Tyr-D-Ser(O-t-Bu)-Gly-Phe-Leu-Thr(DSTBULET) and especially Tyr-D-Ser(O-t-Bu)Gly-Phe-Leu-Thr(O-t-Bu) (BUBU) associated with a satisfactory resistance to peptidases, make them the most suitable {delta}-probes reported to date. In the present paper, we report the synthesis of DSTBULET and BUBU under tritiated forms with high specific radioactivities. These radio-labelled probes will enable extensive in vitro and in vivo investigations of {delta}-opioid receptors properties to be carried out. (author).

    We report the discovery of an unprecedentedly large, 2.2 nm diameter, thiolate protected gold nanocrystal characterized by single crystal X-ray crystallography (sc-XRD), Au 279 (SPh-tBu) 84 named Faradaurate-279 (F-279) in honor of Michael Faraday's (1857) pioneering work on nanoparticles. F-279 nanocrystal has a core-shell structure containing a truncated octahedral core with bulk face-centered cubic-like arrangement, yet a nanomolecule with a precise number of metal atoms and thiolate ligands. The Au 279 S 84 geometry was established from a low-temperature 120 K sc-XRD study at 0.90 Å resolution. The atom counts in core-shell structure of Au 279 follows the mathematical formula for magic number shells: Au@Au 12 @Au 42 @Au 92 @Au 54 , which is further protected by a final shell of Au 48 . Au 249 core is protected by three types of staple motifs, namely: 30 bridging, 18 monomeric, and 6 dimeric staple motifs. Despite the presence of such diverse staple motifs, Au 279 S 84 structure has a chiral pseudo-D 3 symmetry. The core-shell structure can be viewed as nested, concentric polyhedra, containing a total of five forms of Archimedean solids. A comparison between the Au 279 and Au 309 cuboctahedral superatom model in shell-wise growth is illustrated. F-279 can be synthesized and isolated in high purity in milligram quantities using size exclusion chromatography, as evidenced by mass spectrometry. Electrospray ionization-mass spectrometry independently verifies the X-ray diffraction study based heavy atoms formula, Au 279 S 84 , and establishes the molecular formula with the complete ligands, namely, Au 279 (SPh-tBu) 84 . It is also the smallest gold nanocrystal to exhibit metallic behavior, with a surface plasmon resonance band around 510 nm.

    Increasing endoscopy workload in open-access services necessitates adoption of appropriateness criteria to check abuse and improve yield. To assess the appropriateness of referrals for oesophagogastroduodenoscopy (OGD) and its relationship to yield at Korle-Bu Teaching Hospital (KBTH), Accra. Referrals, signs, and symptoms of 375 consecutive patients for diagnostic oesophagogastroduodenoscopy were evaluated over four months. Indications were categorized as appropriate or inappropriate using the American Society of Gastrointestinal Endoscopy (ASGE) guidelines and endoscopic findings (yield) categorized as positive or negative. The relationship between these was analyzed and the diagnostic accuracy of the guidelines determined. There were 209 (55.7%) females, and 316 (84.3%) open-access procedures. Mean age was 46±17 years. Dyspepsia, 272 (72.5%) and epigastric tenderness, 192 (41.4 %) were the commonest symptom and sign respectively. Only 133 (35.5%) reported alarm symptoms. Appropriate referrals constituted 221(58.9%). Inappropriate referral rate was similar for endoscopists and non-endoscopists. Positive yield was 62.7%. Male sex, age > 45 years, haematemesis, persistent vomiting, gastroenterologists' referrals and epigastric tenderness were the best predictors of positive yield. Gastritis, 121 (32.3%), duodenal ulcer, 48 (12.5%) and oesophagitis, 36 (9.6%) were the leading endoscopy diagnoses. Carcinomas were reported only after 45 years and 18 (81.8%) of the cases had alarm symptoms. Inappropriate referral for OGD rate is high in Accra. Yield is improved by adherence to the ASGE guidelines but its accuracy as a screening tool for OGD at Korle- Bu Teaching Hospital is too low to recommend it for adoption.

    Full Text Available Empress of Bulgarians, augusta and basilissa – Maria-Irene Lekapene and the transfer of the idea of imperial feminine in the Medieval Bulgaria Maria Lekapene was a granddaughter of Byzantine Emperor Romanos I Lekapenos. In 927 she married Peter I of Bulgaria. Her marriage, ceremoniously entered into in Constantinople, aimed to strengthen the newly signed Byzantine-Bulgarian peace treaty. Historians attributed to the Empress a significant impact on the political moves of her husband. The Empress was also to introduce a lot of elements of the Byzantine theory of power in Bulgaria.   Cesarzowa Bułgarów, augusta i bazylisa – Maria-Irena Lekapena i transfer bizantyńskiej idei kobiety-władczyni (imperial feminine w średniowiecznej Bułgarii Maria Lekapena była wnuczką cesarza bizantyńskiego Romana I Lekapena. W 927 roku poślubiła władcę Bułgarii, Piotra. Jej małżeństwo, uroczyście zawarte w Konstantynopolu, miało za zadanie umocnić dopiero co podpisany pokój bizantyńsko-bułgarski. Historycy przypisywali carycy znaczny wpływ na polityczne posunięcia jej męża. Władczyni miała też zaszczepić na gruncie bułgarskim wiele elementów bizantyńskiej teorii władzy.

    Full Text Available Background: Non-adherence to treatment is a problem of increasing concern for all stakeholders. This study was designed to determine the prevalence of non-adherence among the clients consulting internists or cardiologists at Bu-Alicina Clinic in Qazvin. Methods: A total number of 400 clients came to Bu-Alicina Clinic (center for internal medicine and cardiology were randomly interviewed through a questionnaire during a two month period in 2003. Self-administered methods were used if the clients applied. The data were interpreted using statistical methods. Results: The clients were between 14 and 78 years old (33.7+8.5 and 57.5% of them were women and 42.5% were men. Of total number, 30.7% were consulting for continuation of their therapies and of these clients, 41.5% had pooradherence to their current therapies. The more educated clients were 1.6 times (OR=1.62; 95% CI=0.71, 3.74 likely to be more adherent to the therapies.There was no significant difference between the internal diseases patients and cardiology patients in this regard (41.7%vs 40%. Of the total number of 400 clients, 79.5% had history of consulting to medical clinics during the last three months and 37.4% of them had non-adherence to their past therapies. The more frequent factors were: forgetfulness (13.3%, not to be able to afford to pay for treatment costs (10.3%, disbelieve to the doctor and consulting another ones (8.4%, long distance (8.4%, feeling that it is not important to take medications (7.4%, side effects (7.4%, disbelieve to the diagnosis (7.1%, religious considerations (6.5%, and misunderstanding or lack of information about the prescription (5.8%. No significant difference was found between men and women on this aspect. Conclusion: Patients need advice, supported information from professionals about their health and therapies. Certain studies must be done to determine the pitfalls and effective interventions address that barriers can be developed. Keywords

    Acceptance testing has been performed on the Siemens e.cam Signature Series (Single Head) Single Photon Emission Computed Tomography (SPECT) system; the first of its kind, at the Nuclear Medicine Department, Korle-Bu Teaching Hospital, Accra. The various tests were performed according to NEMA NU 1 (2001) specifications as far as possible. The most important parameters that characterized the performance of the camera, gantry system, patient bed, collimators, computer system and fundamental software were evaluated based on visual inspection techniques. Various measuring instruments, different kinds of phantoms, point and flood sources containing 99m-Tc were also used for quantitative studies. Tests performed were divided into Physical inspection, intrinsic measurements (without collimator), extrinsic measurements (with collimator) and Single Photon Emission Computed Tomography (SPECT) system measurement. Some results obtained were better than factory specifications, others were within specifications. Other results obtained from this study which did not have factory specifications for comparison can serve as baseline for future measurements and quality control. Although not all the tests originally planned for could be done due to the non-availability of certain phantoms and radionuclide, it had been possible to perform sufficient and relevant tests to ensure that the system had no serious problems and that it can be used for clinical nuclear medicine imaging.

    To determine the burden of gestational diabetes mellitus (GDM) among pregnant women in Accra, Ghana. The present cross-sectional study enrolled women at 20-24 weeks of pregnancy attending their first prenatal clinic at Korle-Bu Teaching Hospital, Accra, between March and November 2013. Participants underwent a 2-hour, 75-g oral glucose tolerance test between 24 and 28 weeks. The odds of GDM among different body mass index (BMI, calculated as weight in kilograms divided by the square of height in meters) groupings were calculated in a multiple logistic regression model. Among 399 women screened, 37 (9.3%) had GDM. Compared with women with a BMI in the normal range (18.50-24.99), obese women (BMI >30.0) had an increased risk of GDM (odds ratio [OR] 2.98, 95% confidence interval [CI] 1.08-8.20; P=0.034]; overweight women (BMI 25.00-29.99) had a slightly elevated risk (OR 1.20, 95% CI 0.41-3.55; P=0.742). Maternal age, parity, education, employment status, place of residence, and previous pregnancy complications did not affect the risk of GDM. GDM was found in 10% of pregnant women in Accra. Women who were obese by 20-24 weeks of pregnancy had a significantly increased risk of GDM. Copyright © 2015 International Federation of Gynecology and Obstetrics. Published by Elsevier Ireland Ltd.

    2012-01-01

    Qualitative method of diagnosis has been the traditional means of diagnosing bone tumours at the Nuclear Medicine Department of the Korle-Bu Teaching Hospital over the years. Although this method is commendable, a more accurate diagnostic means is the quantitative approach. Study on ninety-five patients undergoing bone scans has been performed quantitatively using image J. The patients were administered with activity ranging from 15 to 30 mCi depending on their weights, and were then scanned with an installed e.Cam SPECT system. A 256 x 1024 matrix size was used in acquiring the bone scans. Quantitative analyses performed with the image J, revealed that uptake levels in all selected body parts were higher for metastatic tumours compared to non-metastatic tumours. The average normalised uptake in the recorded metastatic cases was 1.37332 cts/mm 2 /mCi and the corresponding uptake in the non-metastatic cases was 0.85230 cts/mm 2 /mCi. The relative higher uptake in metastatic tumours is attributed to high osteoblastic activity and blood flow in metastatic cases compared to non-metastatic cases. Quantitative assessment of bone scintigrams is recommended for its high accuracy and quicker means of diagnosing.(author)

    Two sequential electrochemical reductions occur for the cluster anion [Ta(6)Cl(12)(OSO(2)CF(3))(6)](2)(-) at 0.89 and 0.29 V vs Ag/AgCl, with the generation [Ta(6)Cl(12)(OSO(2)CF(3))(6)](3)(-) and [Ta(6)Cl(12)(OSO(2)CF(3))(6)](4)(-). Chemical reduction of [Ta(6)Cl(12)(OSO(2)CF(3))(6)](2)(-) by ferrocene produces [Ta(6)Cl(12)(OSO(2)CF(3))(6)](3)(-) with the concomitant shift of the nu(SO(2)) stretch from 1002 to 1018 cm(-)(1). Reaction of [Bu(4)N](2)[Ta(6)Cl(12)(OSO(2)CF(3))(6)] (1) with [Bu(4)N]X (X = Cl, Br, I, NCS) occurs by reduction and substitution, yielding [Bu(4)N](3)[Ta(6)Cl(12)X(6)], where the clusters with X = Br, I, and NCS are new. Spectroscopic (IR and UV-vis) evidence indicates that the reduced cluster core {Ta(6)Cl(12)}(2+) is produced in reaction mixtures of 1 with the halide and pseudohalide ions. Concomitant substitution of the triflate ligands of 1 by X(-) occurs and the rates for the overall reduction and substitution increase in the order X(-) = Cl(-) < Br(-) < NCS(-) < I(-) < CN(-). Reduction of 1 with ferrocene followed by addition of [Bu(4)N]O(2)CCH(3) produces the new cluster [Ta(6)Cl(12)(O(2)CCH(3))(6)](3)(-) isolated as the tetrabutylammonium salt. Cyclic voltammetry and UV-vis spectroscopy on the new clusters [Bu(4)N](3)[Ta(6)Cl(12)X(6)] (X = Br, I, NCS, and O(2)CCH(3)) are reported. Crystal data for [Bu(4)N](3)[Ta(6)Cl(12)(NCS)(6)].CH(2)Cl(2): monoclinic, space group, P2(1)/c (No. 14); a = 25.855(6) Å, b = 21.843(6) Å, c = 16.423(3) Å; beta = 100.03(2) degrees; V = 9133(3) Å(3); Z = 4.

    Full Text Available In our study we try to analyse town based novelist Tarık Buğra’s novels in a ge neral point of wiev. We prefer P rof. Dr. Nurullah Çetin’s “Roman analysing methods” while conducting mentioned study. So, we may reach a general idea about what the novelist try to tell in his novels, what he aims and what kind of results he has. Buğra owns 23 novels totally. Ten of them are printed as boks. The y are listed chronically like: Yalnızlar (1948, Siyah Kehribar (1955, Küçük Ağa (1963 – later as “küçük ağa ankarada, nowadays brougth together as a one book - İbiş’in Rüyası (1970, Firavun İmanı (1978, Gençliğim Eyvah (1979, Dönemeçte (1980, Yağmur Beklerken (1989, Osmancık (1983. Nine of them are narrated by divine observer, and the other one is by subject - observer.in divine - observer novels, the novelist is dominant in the novels and owns an olympic point of view, but in the subject - observer narr ator novels, the subject experiences all the events. Subject - observer narrator novel is Siyah Kehribar, but in some parts, it is seen that divine - observer narrator is used. To the question that in Buğra’s novels, which themes are mentioned, we can sat that the loneliness of humanity, development of characteristic by the effect of society, efforts of the youth for showing themselves, big problems leading to success, a person’s characteristic change and his hero activities, love worhts, holiness of the countr y. İn an overview, Buğra’s novels discuss. male - female relation, nationalism, national struggle, otoman empire history, historical roots, politics and political issues, youth and social corruptin. İn his novels that discuss national struggle, it should bu expressed that he does not handle the issue in a formal way, but he talks about the background. When the mentioned novels are studied about their ends, it is seen that they have surprising, tragical and open - ended ends, even in most novels all

    Organ and effective dose to ninety (90) patients undergoing myelogram, urethrogram, barium swallow, barium meal and barium enema examinations at the KorIe-Bu Teaching Hospital was estimated using the Monte Carlo Code (PCXMC). Free in air measurements were made with a calibrated ionisation chamber to estimate the entrance surface air kerma for each examination. Evaluation of fluoroscopy beam on time and number of radiographs taken per patient was done for all the examinations considered and studies were done on how they affect patient dose. Dose area product (DAP) was calculated from the entrance surface air kerma and the area of the beam on the surface of the patient and compared with internationally accepted reference levels. Excess relative risk of site specific solid cancer and all solid cancers excluding thyroid and Non-melanoma skin cancers incidences were estimated for the various examinations using Biological Effects of Ionising Radiation VII Committee risk model from the knowledge of the mean effective doses for each examination. The mean effective dose was found to be 0.29 :±: 0.07 mSv for urethrogram, 0.84:±: 0.13 mSv for barium swallow, 3.15 :±: 0.44 mSv for barium meal, 6.24 :±: 0.7 mSv for barium enema and 0.38 :I: 0.05 mSv for myelogram examinations. The estimated mean dose area product (DAP) was found to be 3.55 :±: 0.95 Gycm2 for urethrogram, 16.44:1: 2.60 Gycm2 for barium swallow, 50.81 :±: 7.04 Gycm2 for barium meal, 99.69 :±: 10.85 Gycm2 for barium enema and 9.32 :±: 0.99 Gycm2 for myelogram examinations. The estimated excess relative risk for the occurrence of all solid cancer was found to be 9.5700E-S and 1.6530E-4 for males and females respectively undergoing urethrogram examination, 2.7720E-4 and 4.7880E-4 for males and females respectively undergoing barium swallow examination, 1.0395E-3 and 1.7955E-3 for males and females respectively undergoing barium meal examination, 2.0592E-3 and 3.5568E-3 for males and females respectively

    To study the indications for endoscopy, the endoscopic diagnosis and other lessons learnt. A retrospective and prospective audit of all upper gastrointestinal endoscopies performed in the Endoscopy Unit of the Korle-Bu Teaching Hospital from January 1995 to December 2002 was performed. A total of 6977 patients, 3777 males and 3200 females with age range 1 year 8 months to 93 years were endoscoped. The mean age of males was 43.5 +/- 0.5 and females 43.7 +/- 0.6 years. Epigastric pain (42.5%), dyspepsia (32.8%) and haematemesis and melaena (14.2%) were the commonest reasons for endoscopy. Chronic duodenal ulcer (19.6%), acute gastritis (12.7%), duodenitis (10.2%), oesophagitis (7.5%) were the commonest diagnoses. Normal endoscopy was reported in 41.1% patients, and was higher in the younger age group compared to the older (R = 0.973, P<0.001). Nine hundred and ninety (14.2%) patients were endoscoped for haematemesis and melaena of which chronic duodenal ulcer (32.1%), gastritis/gastric erosions (12.8%), oesophageal varices (9.8%), carcinoma of the stomach (6.4%), and duodenitis (4.2%), were the commonest causes. No lesion was found in 20.6% of these patients. Urease test was positive in 75% of all biopsy specimen and 85% in chronic duodenal ulcer, gastritis and duodenitis. The normal endoscopy rate is high and needs to be reduced in order to help prolong the lives of the endoscopes. Chronic duodenal ulcer is usually associated with H. pylori infection and is the commonest cause of upper gastrointestinal bleeding.

    The iodoform reaction has long been used as a qualitative test for acetyl and/or ethanol units in organic molecules. However, its synthetic applications are quite limited. Here, we describe a tuned iodoform reaction for oxidative demethylation reaction with I 2 and t-BuOK in t-BuOH, in which in situ-generated t-BuOI serves as the chemoselective iodinating agent. This system enables one-step conversion of levulinic acid to succinic acid, a major four-carbon chemical feedstock. This oxidative demethylation is also applicable to other compounds containing an acetyl group/ethanol unit, affording the corresponding carboxylic acids in a selective manner.

  20. On the inversion of the 1 Bu and 2 Ag electronic states in α,ω-diphenylpolyenes

    Science.gov (United States)

    Catalán, J.

    2003-07-01

    An alternative model to that of the inversion of the states 1Bu and 2Ag is proposed for interpreting the photophysics of the α,ω-diphenylpolyenes. This model is based upon the existence of two chemical structures with Bu symmetry, which may be ascribed to the same excited electronic state 1Bu. One of the two chemical structures corresponds to the Franck-Condon structure with conjugated single and double bonds for the polyene chain, and another consists of a nearly equivalent series of partial double bonds along the polyene chain. The latter relaxed structure is consistent with the observation of high torsional energy barriers and low photoisomerization quantum yields for diphenylhexatriene in the singlet excited state manifold. Interestingly, such a simple quantum model as that of the particle in a one-dimensional box provides quite an accurate description of the absorption spectroscopic properties of these major compounds. This is partly the result of the most stable structures for these compounds being of the all-trans type; such structures increase in length as additional ethylene units are added, which makes them very similar to a one-dimensional box becoming increasingly longer.

    Full Text Available The immured woman, Odysseus and Bulgarian Easter: Toncho Zhechev and the quest for a conservative myth This article reflects on Bulgarian Easter, or Bulgarian Passions, a 1975 book by the Bulgarian humanist Toncho Zhechev, once regarded in Communist Bulgaria as a call for a return to traditional values. Zhechev’s quasi-conservative ideological turn (which in formal terms ran counter to the precepts of Marxist ideology was based, among other things, on a complex and richly layered reinterpretation of Izvorat na belonogata, a poem by Petko R. Slaveykov (The Spring of the White-Legged Girl, 1873, and on its revitalisation of the myths of the immured woman and of Odysseus. The way Zhechev positively reinvented a manufactured archaic tradition as a mainstay of primeval wisdom and mysticism offers an interesting testimony to the quest for a concept of “integral traditionalism” in a form that was reconcilable with the progressism of the Zhivkov era.   Zamurowana niewiasta, Odyseusz i Bułgarska Wielkanoc.

    Treatment of P 6 C 4 t Bu 4 with the Lewis acid AlI 3 in toluene at room temperature unexpectedly results in a structural rearrangement affording the ionic complex [P 6 C 4 t Bu 4 H][AlI 4 ] which was fully characterized by multinuclear NMR spectroscopy and a single crystal X-ray diffraction study. Supportive evidence that the reaction might involve a simple intermediate Lewis acid-base adduct [AlI 3 (η 1 -P 6 C 4 t Bu 4 )] came from the isolation on one occasion of small number of crystals of the bis-Al adduct [(AlI)μ-(P 6 C 4 t Bu 4 )(AlI 3 )], whose molecular structure was also confirmed by a single crystal X-ray diffraction study.

    Both Bovine herpesvirus (BoHV-1) and Bubaline herpesvirus (BuHV-1) have been reported to cross the species barrier. Antibody seroconversion in glycoprotein E (gE) blocking ELISA during BuHV-1 infection has been documented. Recent diagnostic efforts have focused on the development and application of discriminatory tests to distinguish between infections with BoHV-1 and BuHV-1. To evaluate the impact and distribution of these two infections in water buffalo farms in two regions (Piedmont (n = 3) and Campania (n = 10), Italy) where infectious bovine rhinotracheitis control programs have been implemented. Sampling was carried out on 13 buffalo farms comprising 1089 animals using specific gE-indirect ELISA's test able to discriminate among BoHV-1 and BuHV-1 infections. 59.0% of animals reacted positive to ELISA (irrespective of whether BoHV-1 or BuHV-1 antigen was used) and 86.4% of these were reactive to BuHV-1 only, whereas 11.8% showed absorbance values for both antigens and were classified as inconclusive. There was a statistically significant age-related difference in BuHV-1 infection rates but not in overall individual (47% vs. 58%) or herd prevalence (100% vs. 90%) of infection between the two regions. The low percentage of sera reactive to BoHV-1 (1.8%, 12/643) indicates that BuHV-1 may be the main circulating alphaherpesvirus infection in Mediterranean water buffalo in the two study areas. Since Bubalus bubalis is included in Directive 64/432/EEC on animal health problems affecting intra-community trade in bovine animals, diagnostic testing with nonspecific ELISA for BoHV-1 infection in buffalo may yield false-positive reactions. This scenario could lead to economic losses and hamper buffalo trade and movement, particularly for reproduction purposes.

    Full Text Available En la memoria colectiva de los europeos, la Guerra Civil española ocupa un lugar destacado. El lenguaje cinematográfico y la representación fílmica de esa contienda forman un ámbito relevante en el que estudiar algunos rasgos de la matriz cultural europea. El presente trabajo selecciona parte de la producción fílmica de propaganda del gobierno republicano, en concreto los filmes de montaje supervisados por Luis Buñuel. Al inicio de la contienda el cineasta aragonés vuelve a París siguiendo las indicaciones del Ministerio español de Asuntos Exteriores para colaborar, en la embajada española en la capital francesa, en diversas labores de contraespionaje y propaganda. Entre ellas y principalmente, Buñuel se ocupa de reunir, organizar y montar diverso material fílmico prorrepublicano. A diferencia de otras producciones proyectadas en España, los filmes parisinos de propaganda republicana se caracterizaron, en términos generales, por estar dirigidas a públicos de distintos países europeos con el objetivo de romper la doctrina de no intervención en el conflicto y se inscriben dentro de las teorías y concepción de Buñuel sobre el documentalismo filmado, donde primaba lo reflexivo y los recursos psicológicos que motivaran a la acción o a la toma de conciencia individual. El presente texto se ocupa, en ese contexto, de la descripción y el análisis del lenguaje y las prácticas fílmicas en esos años. De todas ellas, el filme «España, 1936» (1937, es a la vez un ejemplo emblemático y singular.The Spanish Civil War occupies an important place in the European collective memory. The film language and depiction of that conflict provide an important platform from which to study certain features of the European cultural matrix.

    Background Psychological distress contributes to the development of hypertension in young adults. This trial assessed the effects of a mind–body intervention on blood pressure (BP), psychological distress, and coping in college students. Methods This was a randomized controlled trial (RCT) of 298 university students randomly allocated to either the Transcendental Meditation (TM) program or wait-list control. At baseline and after 3 months, BP, psychological distress, and coping ability were assessed. A subgroup of 159 subjects at risk for hypertension was analyzed similarly. Results Changes in systolic BP (SBP)/diastolic BP (DBP) for the overall sample were −2.0/−1.2 mm Hg for the TM group compared to +0.4/+0.5 mm Hg for controls (P = 0.15, P = 0.15, respectively). Changes in SBP/DBP for the hypertension risk subgroup were −5.0/−2.8 mm Hg for the TM group compared to +1.3/+1.2 mm Hg for controls (P = 0.014, P = 0.028, respectively). Significant improvements were found in total psychological distress, anxiety, depression, anger/hostility, and coping (P values < 0.05). Changes in psychological distress and coping correlated with changes in SBP (P values < 0.05) and DBP (P values < 0.08). Conclusions This is the first RCT to demonstrate that a selected mind–body intervention, the TM program, decreased BP in association with decreased psychological distress, and increased coping in young adults at risk for hypertension. This mind–body program may reduce the risk for future development of hypertension in young adults. PMID:19798037

    2009-05-01

    Full Text Available A substância deste artigo consiste na leitura de alguns autores que tratam do mito e do imaginário sem acatar as propostas que se fundamentam no racionalismo cartesiano e no influente positivismo do século XIX. Tais autores, como Eliade e Durand, desenvolveram no século XX um estudo do mito e da imagem com a perspectiva de uma orientação epistemológica que surgira na intenção de se constituir como uma nova abordagem científica, levando o elemento imaginativo e mítico ao encontro da realidade imediata. O argumento principal dessa nova abordagem, que aqui tentamos minimamente apresentar, em torno do mito e da imagem, opõe-se ao dualismo filosófico que coloca em extremos o materialismo e o subjetivismo; dessa forma, tais autores chegaram a uma conclusão que ratifica a retórica da imagem simbólica e reafirma a força diretiva dos mitos, deixando o ditame imaginário de ser uma simples abstração ou engano,  uma vez que segue regras mais profundas e é significativamente responsável pela dinâmica social ou pelas produções individuais representativas da cultura, no tempo e no espaço.Palavras-chave: Mito; Imaginário; Nova epistemologia; Século XX.ABSTRACTThis article resentats some authors who treat myth and the imaginary without taking into consideration the proposals based on Cartesian rationalism and on 19th-century influent positivism. Those authors, such as Eliade and Durand, developed a study of myth and image in the perspective of an epistemological orientation aimed at elaborating a new scientific approach, promoting the encounter between imaginative and mythical elements and immediate reality. The main point in this approach in terms of myth and image, which we attempt to briefly present here, is opposed to the philosophical dualism that sets materialism and subjectivism distantly apart. Thus, those authors eventually reached a conclusion that ratifies the rhetoric of symbolic image and reaffirms the guiding strength

    Full Text Available The creation of protected areas can bring socio-economic development to the places where they were created. Particularly through tourism, it may generate some benefits such as incomes and the con- servation. Therefore, the way the community is structured to foster these benefits can lead to social change processes. In this context, we sought to analyze the cooperative relations between social actors, like the Buíque (Pernambuco, Brazil residents, to promote tourism in the Catimbau National Park, consi- dering the local development concept. This research was developed over a specialization course, and it is a qualitative study case, which includes literature review and field research with application of interviews. Therefore, it was found that, despite the existence of some ‘cooperative’ interactions, not all agents parti- cipate in this process. So, among other things discussed, it is believed that the Catimbau National Park might contribute to local development in future.

    Smartphones and tablets are being used widely in the Western World creating benefits in healthcare. The Ministry of Health in Ghana has an e-Health strategy, with the aim of integrating such resources into healthcare. Whilst there are numerous mHealth projects going on in Ghana, there is little evidence of doctors using such devices in their practice. A qualitative study was undertaken in Korle-Bu Teaching Hospital. Random sampling was used to identify House Officers, who engaged in semi-structured interviews. Interviews were recorded, transcribed and analysed using thematic content analysis. Consent was gained from all participants and the University of Leeds granted ethical approval. The results demonstrate that current House Officers began using smartphones and tablets at various stages during medical school. Their use has increased since qualification. Although the overall use has increased, some staff remain resistant to the use of smartphones and tablets. In the future, the integration of smartphones and tablets into medical practice can be improved by integration with the medical curriculum and accepted practice. House Officers are routinely using smartphones and tablets to assist them in their daily practice. The use is informal and is peer led. Whilst they bring many benefits, there are issues, which need to be addressed. In Korle-Bu Teaching Hospital integrating smartphone and tablet use into practice is feasible and would prove beneficial.

    Introduction: A positron emission tomography (PET) probe with ultra-high specific radioactivity (SA) enables measuring high receptor specific binding in brain regions by avoiding mass effect of the PET probe itself. It has been reported that PET probe with ultra-high SA can detect small change caused by endogenous or exogenous ligand. Recently, Kealey et al. developed [ 11 C]BU99008, a more potent PET probe for I 2 -imidazoline receptors (I 2 Rs) imaging, with a conventional SA (mean 76 GBq/μmol) showed higher specific binding in the brain. Here, to detect small change of specific binding for I 2 Rs caused by endogenous or exogenous ligand in an extremely small region, such as hypothalamus in the brain, we synthesized and evaluated [ 11 C]BU99008 with ultra-high SA as a useful PET probe for small-animal PET imaging of I 2 Rs. Methods: [ 11 C]BU99008 was prepared by [ 11 C]methylation of N-desmethyl precursor with [ 11 C]methyl iodide. Biodistribution, metabolite analysis, and brain PET studies were conducted in rats. Results: [ 11 C]BU99008 with ultra-high SA in the range of 5400–16,600 GBq/μmol were successfully synthesized (n = 7), and had appropriate radioactivity for in vivo study. In the biodistribution study, the mean radioactivity levels in all investigated tissues except for the kidney did not show significant difference between [ 11 C]BU99008 with ultra-high SA and that with conventional SA. In the metabolite analysis, the percentage of unchanged [ 11 C]BU99008 at 30 min after the injection of probes with ultra-high and conventional SA was similar in rat brain and plasma. In the PET study of rats' brain, radioactivity level (AUC 30–60 min ) in the hypothalamus of rats injected with [ 11 C]BU99008 with ultra-high SA (64 [SUV ∙ min]) was significantly higher than that observed for that with conventional SA (50 [SUV ∙ min]). The specific binding of [ 11 C]BU99008 with ultra-high SA (86% of total binding) for I 2 R was higher than that of

    Traditional Chinese medicine is the clinical experience accumulated by Chinese people against diseases. Da-Bu-Yin-Wan is a famous traditional Chinese medicine formula consisting of Phellodendri amurensis Rupr., Anemarrhenae asphodeloides Bge., Radix Rehmanniae Preparata and Chinemys reevesii. In this study, ultra high performance liquid chromatography with electrospray ionization quadrupole time-of-flight high-definition mass spectrometry with the control software of Masslynx (V4.1) was established for comprehensive screening and identification of the chemical constituents and serum metabolites of Da-Bu-Yin-Wan in vivo and in vitro. Consequently, 70 peaks in the methanol extract from Da-Bu-Yin-Wan and 38 peaks absorbed into rat blood were characterized. The 70 constituents in vitro included alkaloids, flavonoids, polysaccharide, limonoids, flavonoid, etc. And the 38 constituents consist of 22 absorbed prototypes and 16 metabolites of Da-Bu-Yin-Wan absorbed in vivo. We fully clarified the chemical constituents of Da-Bu-Yin-Wan and provided a scientific strategy for the screening and characterization of the chemical constituents and metabolites of traditional Chinese medicine in vitro and in vivo. © 2017 WILEY-VCH Verlag GmbH & Co.

    The thyristor converter put into operation in the course of reconstruction of the power supply of the BU-70 synchrotron ring electromagnet is described. The converter is designed for maximum current I=5 kA and voltage 2x10 kV and consists of four three-phase bridge rectifiers connected in parallel in the equivalent twelve-phase circuit. The total number of thyristors - 2304. The thyristor power supply operated over 7000 h. The conclusion is drawn that the use of thyristors allows one to sharply reduce the time of system tuning for nominal operation mode, reduce water consumption for convertercooling and considerably improve the working conditions ofthe maintenance personnel

    Full Text Available We have studied the fossil Rhinocerotidae from Buñol (Valencia, Spain. It is realized as stratigraphic synthesis of the deposit and dated as Orleanium Mammal Age (lower-middle Aragonium, which is equivalent to the 4b Neogene MammaL Unit (zonation of Mein, 1976. We conclude that the fossil association is a thanatocoenosis, with strongly rounded elements. The paleoenvironment, in which this association was accumulated, was a marsh zone in the distal part of an alluvial fan. Two species of Rhinocerotidae have been determined, one of the ,genus Acerotherium and another of the genus Dicerorhinus. The second is more abundant than the former and probably it would be adapted to a marshy habitat. We describe and figure the more representative material of both species.

    The expression of IL-5 correlated tightly with the maturation and differentiation of eosinophils, and is considered as a cytokine responsible for allergic inflammation. We report here that inhibition of HDAC activity by Trichostatin A (TSA) and sodium butyrate (NaBu), the two specific HDAC inhibitors, resulted in the elevation of both endogenous and exogenous activity of IL-5 promoter. We demonstrated that both the mRNA expression and protein production of IL-5 were stimulated by TSA and NaBu treatments. ChIP assays showed that treatments of TSA and NaBu caused hyperacetylation of histones H3 and H4 on IL-5 promoter in Jurkat cells, which consequently promoted the exogenous luciferase activity driven by this promoter. Moreover, site-directed mutagenesis studies showed that the binding sites for transcription factors NFAT, GATA3 and YY1 on IL-5 promoter were critical for the effects of TSA and NaBu, suggesting that the transcriptional activation of IL-5 gene by these inhibitors was achieved by affecting HDAC function on IL-5 promoter via transcription factors. These data will contribute to elucidating the unique mechanism of IL-5 transcriptional control and to the therapy of allergic disorders related to IL-5.

    To examine factors influencing contraceptive use among women living with HIV/AIDS. The present cross-sectional study included a randomly selected sample of sexually active females aged 15-60 years who were living with HIV/AIDS and receiving care at the HIV Clinic, Korle Bu Teaching Hospital, Accra, Ghana, between September 1 and November 31, 2016. Data were collected via a structured interviewer-administered questionnaire. Among 202 women who completed the survey, 50 (24.7%) were using contraceptives. Of the women using contraception, 39 (78%) were married and 6 (12%) were cohabiting. Twenty-eight (56%) reported that their primary sexual partners were HIV-positive, 14 (28%) had HIV-negative partners, and 8 (16%) did not know their partner's HIV status. Condoms were used by 42 (84%) women and the majority (41 [82%]) wanted to have more children; almost all (47 [94%]) had received counseling on contraceptive use. Overall, 133 (65.8%) and 45 (22.3%) women reported that they would prefer to share their family planning concerns with a doctor and nurse, respectively, at the HIV clinic. Women living with HIV/AIDS desired more children but preferred to share their family planning concerns with their clinician at the HIV clinic. Integrating HIV care and reproductive health services could help these women achieve childbearing goals safely. © 2018 International Federation of Gynecology and Obstetrics.

    Full Text Available Here, we describe pollen grains extracted from a Pleistocene-Holocene sediment core (BU-91-GL-05; 22°48'45"S; 41°54'13"W taken from the Albacora Slope (22°48'45"S; 41°54'13"W, located in the Campos Basin of the northern region of the state of Rio de Janeiro, Brazil. The analysis resulted in the identification and morphological description of 46 types of pollen: one of a gymnosperm genus (Podocarpus; and 45 of angiosperm taxa across 27 families-one family of monocotyledons (Poaceae and 26 families (30 types of dicotyledons. The most common angiosperm families were Amaranthaceae (Chenopodium, Amaranthus and Gomphrena; Fabaceae (Fabaceae type, Bauhinia, Inga and Canavalia; Malpighiaceae (Tetrapteris, Heteropteris and Peixotoa; Malvaceae (Sida, Abutilon, Hibiscus and Pseudobombax; Rubiaceae (Faramea, Borreria and Psychotria; Asteraceae (Eupatorium and tribe Vernonieae; Bignoniaceae (Bignoniaceae type, Adenocalymma and Tabebuia; and Onagraceae (Fuchsia and Ludwigia. The palynoflora in this study are associated with dense montane and submontane Atlantic Forest, semideciduous forest and restinga (coastal woodland, all of which are present in the state of Rio de Janeiro. Palynological analysis can provide important data about paleovegetation and paleoclimatic changes in the studied area during the Quaternary, specifically in the last 145,000 years.

    Full Text Available Da-Bu-Yin-Wan (DBYW and Qian-Zheng-San (QZS, two classic traditional Chinese medicinal formulas, were clinically employed to treat Parkinson’s disease (PD. Our previous studies demonstrated neuroprotective effects of them on mitochondrial function in PD mice induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP. The purpose of this research was to investigate their possible mechanisms in the light of mitochondrial ATP-sensitive potassium (mitoKATP channels. The neuroprotective effect of DBYW and QZS on dopamine (DA neurons in substantia nigra (SN in the MPTP-induced PD mice was investigated by behavioral test (pole test and immunohistochemistry. Adenosine triphosphate (ATP level in the midbrain tissue was detected by firefly luciferase method. MitoKATP channel subunits SUR1 and Kir6.2 mRNA and protein expressions were tested by real-time PCR (RT-PCR and Western blot. It was observed that DBYW and/or QZS served to ameliorate MPTP-induced behavioral impairment and prevent the loss of substantia nigra dopamine neurons, as well as increase ATP level in the midbrain tissue and downregulate SUR1 expression at mRNA and protein levels with no marked influence on Kir6.2. We concluded that DBYW and QZS exhibit neuroprotective effects probably through the regulation of ATP level and mitoKATP channel subunit expressions.

    Phosphagermaallene Tip(t-Bu)Ge=C=PMes* (1; Mes* = 2,4,6-tri-tert-butylphenyl, Tip = 2,4,6-triisopropylphenyl) gives, with N-benzylidenemethylamine and pivalonitrile, [2+2] cycloadditions between the Ge=C double bond and the C=N and C≡N unsaturations, leading to the formation of the corresponding four-membered heterocycles 2 and 9. With N-tert-butyl-α-phenylnitrone and benzonitrile oxide, [2+3] cycloadditions occur to form the five-membered ring derivatives 6 and 7. By treatment of 1 with derivatives which possess weak acidic hydrogens in α of the C=N or C≡N multiple bond, two types of reactions were observed: an ene reaction with methyl(benzylideneamino)acetate and a 1,2 addition with acetonitrile to afford azadienyl(germyl)ether (4) and 3-germa-1-phosphapropene (8), respectively. In the case of benzonitrile, phosphagermaallene 1 behaves as a 1,3-dipole, to give, via a cyclic phosphagermacarbene intermediate, the tricyclic derivative 10.

    The risk for occupational exposure to HIV is a serious public health problem that is well characterized in the developed world, but less so in the developing countries such as Ghana. This study was undertaken to examine the characteristics of occupational exposure to HIV and the utilization of a risk assessment system (RAS)-based postexposure prophylaxis (PEP) among health care workers (HCWs) and health care students (HCSs) in the Korle-Bu Teaching Hospital (KBTH). During the study period (January 2005-December 2010), a total of 260 and 35 exposures were reported by HCWs and HCSs, respectively. Ward attendants reported the highest incidence rate of 6.46 of 100 person-years (P-Y). The incidence of high-risk exposures was 0.33 of 100 P-Y (n = 65); 60.0% occurred during a procedure of disposing of a needle and 24.6% during a cannula insertion. A total of 289 of the 295 individuals were administered PEP, of which 181 (62.6%) completed the 6-month follow-up testing schedule and none sero-converted. This shows that with a good RAS in place, it is possible to deploy an effective PEP program in a typical African teaching hospital like the KBTH in Accra, Ghana. © The Author(s) 2013.

    Systematic substitution of His(6) residue using non-selective hMC4R pentapeptide agonist (Bu-His(6)-DPhe(7)-Arg(8)-Trp(9)-Gly(10)-NH(2)) as the template led to the identification of Bu-Atc(6)(2-aminotetraline-2-carboxylic acid)-DPhe(7)-Arg(8)-Trp(9)-Gly(10)-NH(2) which showed moderate selectivity towards hMC4R over hMC1R. Further SAR studies resulted in the discovery of Penta-5-BrAtc(6)-DPhe(7)-Arg(8)-Trp(9)-Gly(10)-NH(2) and Penta-5-Me(2)NAtc(6)-DPhe(7)-Arg(8)-Trp(9)-Gly(10)-NH(2) which are potent hMC4R agonists and are inactive in hMC1R, hMC3R and hMC5R agonist assays.

  2. Kinetics and Mechanism of the Polymerization of Methyl Methacrylate in a Y(acac)3/n-BuMgCl System

    Institute of Scientific and Technical Information of China (English)

    2000-01-01

    Based on the kinetics equation proposed by T. Kagiya, the kinetic study on the polymerization of methyl methacrylate(MMA) by Y(acac)3/n-BuMgCl was carried out with a dilatometer. It was found that the rate of propagation is the first order with respect to the concentration of both active center and monomer. Thus, the equation of propagation rate can be described as Rp=Kp[c*][M]. In addition, the instantaneous chain initiation and single molecular termination were concluded for the present system. The activation energy is close to 32 kJ/mol. In the polymerization, n-BuMgCl acts not only as the cocatalyst, but also as chain transfer agent with cI=3.6×10-4.

    There is evidence for alterations in imidazoline(2) (I(2)) receptor density in depressed patients. Selective I(2) receptor ligands modulate central monoamine levels and activate the hypothalamo-pituitary-adrenal (HPA) axis and may have potential as antidepressants. To study the behavioral effects of the selective I(2) receptor ligand BU224 in the rat forced swim test (FST) and its effects on the HPA axis and central monoaminergic responses. Rats received saline or BU224 (10 mg/kg IP) 24, 18 and 1 h prior to 15 min exposure to the FST. Saline- and BU224-treated non-stressed groups were included. Time spent immobile, struggling and swimming calmly was measured. Plasma adrenocorticotrophic hormone (ACTH) and corticosterone levels 90 min post-BU224 were measured in addition to tissue levels of monoamines and metabolites in the frontal cortex, hippocampus and hypothalamus. Administration of BU224 significantly reduced immobility and increased mild swimming without affecting struggling. Exposure to the FST significantly increased plasma ACTH and corticosterone levels. BU224 administration also increased ACTH and potentiated the ACTH response to FST with no effect on corticosterone. BU224 administration significantly increased frontal cortex 5-hydroxytryptamine (5-HT) levels and decreased 5-HT turnover in the frontal cortex and hypothalamus of rats exposed to FST. In non-stressed rats, BU224 decreased 5-HT turnover in the hippocampus and hypothalamus and decreased norepinephrine turnover in the frontal cortex. The selective I(2) receptor ligand BU224 reduces immobility of rats in the FST, indicative of antidepressant-like activity. This effect is accompanied by alterations in HPA axis and central monoaminergic activity.

    Ghana is currently developing its provision of dermatology services. Epidemiologic studies of the skin diseases seen by Ghanaian dermatologists are needed to guide these efforts. We aimed to describe the skin conditions seen by and management practices of Ghanaian dermatologists in a specialized clinic. We conducted a chart review of new patients presenting to the Korle Bu Teaching Hospital dermatology clinic during 2014. Among the 529 patients studied, 700 discrete diagnoses were made. The most commonly diagnosed skin conditions were infections (24.6%) and dermatitis (24.6%); atopic dermatitis (8.4%), acne vulgaris (5.3%) and scabies (5.1%) were the most common specific diagnoses. Among infants, children, and adolescents, the most common diagnosis was atopic dermatitis (31.7%, 30.0%, and 14.9%, respectively). Acne vulgaris (12.0%) was the most common skin condition diagnosed in young adults. Irritant contact dermatitis (6.9%) was most common among adults. Lichen planus (9.9%) was the most commonly diagnosed skin condition in the senior population. Diagnoses made by dermatologists differed from the referral diagnosis documented by primary care providers for 65.8% of patients. The most frequently recommended treatments were antihistamines (47.8%) and topical steroids (38.4%). Only 18 diagnostic biopsies were performed. Our study summarizes the skin diseases seen and management practices of Ghanaian dermatologists in a specialized clinic at a large public teaching hospital. The results of this study can help to guide future dermatology education and development efforts in Ghana.

    The aim of this study is to estimate the effective dose and assess the lifetime attributable risk of cancer incidence of patients undergoing computed tomography scan at the korle-bu Teaching Hospital. Data on volume CT dose index (CTDI vol) and dose length product (DLP ) displayed on the scanner control console was recorded after confirmation of the results by performing independent checks on a phantom. The effective doses were estimated using the displayed and the anatomic region specific conversion factors (K ). The average effective dose for the head, abdomen, chest, neck, and pelvis were 3.63± 2.39mSv, 15.37±8.49 mSv, 12.72 ± 13.97 mSv, 4.04 ± 1.47 mSv and 15.8 ± 3.59 mSv respectively. Effective doses for the head and neck were within the typical range of (1-10mSv) for CT examinations whilst abdomen, chest and pelvis were above 10mSv. The average life attributable risk of cancer incidence for each region of examination were determined from the effective dose, sex and age using the model proposed in BEIR VII report . The average cancer risk incidence for head, neck, chest, abdomen and pelvis examinations were low in the range 1 in 10,000 to 1 in 1,000. There were wide variations in the effective dose values obtained for the same region under examination. This trend calls for the optimization of CT examination protocols to be established to ensure that patient doses are as low as reasonably achievable, economic and social factors being taken into account.

    2009-06-01

    Staff and the general public's safety during the operation of the 137 Cs brachytherapy unit at the Korle Bu teaching hospital depends on the adequacy of the shielding of the facility. Shielding design of the brachytherapy unit at the hospital was based on postulated workload and postulated occupancy factors to critical locations at the facility where the public and staff may occupy. This facility has been in existence for the past twelve (12) years and has accumulated operational workload data which differs from the postulated one. A study was carried out to re-evaluate the integrity of the biological shielding of the 137 Cs brachytherapy unit. This study analyzed the accumulated workload data and used the information to perform shielding calculations to verify the adequacy of the biological shielding thicknesses to provide sufficient protection of staff and the public. Dose rate calculations were verified by measurements with calibrated dose rate meters. This provided the basis for determining the current state of protection and safety for staff and the general public. The results show that despite the variation in actual and postulated workloads, the dose rates were below the reference values of 0.5μSv/h for public areas and 7.5μSv/h for controlled areas. It was confirmed that the present shielding thickness of 535 mm can accommodate a high dose rate (HDR) 192 Ir source with activity in the range 370 - 570 GBq with an operational workload of 30 patients per week and an average treatment time of 10 minutes.

    2010-01-01

    In this work management of paediatric patients doses for Computed Tomography examinations have been studied at Korle-Bu Teaching Hospital. The assessment of the management system involved: evaluation of the frequency of examinations, comparison of techniques factors used for adult and children; estimation of CTDI w , CTDI vol , DLP and effective dose; evaluation of quality assurance and quality control programmes to optimise paediatric patient doses. The frequency of CT examinations for paediatric patients accounted for 1300 out 5200 examinations (25%) of the total examinations recorded for the year 2008 which is five times that of the East European countries, indicating an overuse of CT examinations for children not taking into account paediatric patient anatomy and the section of the body being scanned. Adult CT exposure parameters such as the KV, mAs, scan length, pitch, and collimation values were being used in paediatric CT examination. Effective dose estimated for children were higher than that for adults by factors 5.1, 1.8, 3.1 and 3.9 more for head, chest, abdomen and pelvis examinations respectively. From the questionnaire administered and dosimetry results there was no established justification policy, procedures and referral criteria for CT examination requests for children. There was no Quality Assurance Committee to see to the implementation of dose management system dedicated to paediatrics patients. There was the need for the Hospital Authorities to formulate policies in the training of CT equipment operators, radiographers and radiographers and radiologist in modern CT technology as well as in the selection of appropriate parameters tailored to individual patient size that can achieve desirable diagnostic image quality at low doses.

    Ultrastable gold nanomolecule Au144(SCH2CH2Ph)60 upon etching with excess tert-butylbenzenethiol undergoes a core-size conversion and compositional change to form an entirely new core of Au133(SPh-tBu)52. This conversion was studied using high-resolution electrospray mass spectrometry which shows that the core size conversion is initiated after 22 ligand exchanges, suggesting a relatively high stability of the Au144(SCH2CH2Ph)38(SPh-tBu)22 intermediate. The Au144 → Au133 core size conversion is surprisingly different from the Au144 → Au99 core conversion reported in the case of thiophenol, -SPh. Theoretical analysis and ab initio molecular dynamics simulations show that rigid p-tBu groups play a crucial role by reducing the cluster structural freedom, and protecting the cluster from adsorption of exogenous and reactive species, thus rationalizing the kinetic factors that stabilize the Au133 core size. This 144-atom to 133-atom nanomolecule's compositional change is reflected in optical spectroscopy and electrochemistry.

    Reaction of mixed valence ruthenium tetracarboxylates [Ru(2)(II,III)(R(1)COO)(2)(R(2)COO)(2)Cl] (R(1) = Me, R(2) = 2,4,6-(i)Pr-Ph or R(1) = R(2) = (t)Bu) with two equivalents of the octahedral manganese complex [Mn(I)(CO)(CN)((t)BuNC)(4)] leads to the formation of cyanide bridged heteronuclear coordination compounds of the general formula {[Ru(2)(II,III)(R(1)COO)(2)(R(2)COO)(2)][Mn(I)(CO)(CN)((t)BuNC)(4)](2)}Cl. In solution an intramolecular electron transfer from manganese towards the multiply bonded Ru(2) core occurs that is verified by EPR and IR spectroscopy, magnetic measurements and DFT calculations. Nevertheless, disproportionation of an initially formed {Mn(I)-Ru(2)(II,III)-Mn(I)}(+) adduct into {Mn(II)-Ru(2)(II,III)-Mn(I)}(2+) and {Mn(I)-Ru(2)(II,II)-Mn(I)} species cannot be completely ruled out.

    and Adolescent Health Promotion', Salutogenesis - from theory to practice' and Health, Stress and Coping'. More than half of all doctoral theses undertaken at NHV during these years had health promotion as their theme. As a derivative, the Nordic Health Promotion Research Network (NHPRN) was established in 2007......In 1953 when the Nordic School of Public Health was founded, the aim of public health programmes was disease prevention more than health promotion. This was not unusual, since at this time health usually was seen as the opposite of disease and illness. However, with the Ottawa Charter of 1986......, the World Health Organization made a crucial change to view health not as a goal in itself but as the means to a full life. In this way, health promotion became a first priority and fundamental action for the modern society. This insight eventually reached NHV and in 2002 - 50 years after the foundation...

    A variety of automatic blood measurement devices with diverse features have been introduced to the medical markets recently. Among these devices, models that measure at the wrist have become increasingly popular in self measurements. The objective of this study was to evaluate the accuracy of the Samsung SBM-100A and Microlife BP 3BU1-5 wrist blood pressure devices against the mercury sphygmomanometer in adults according to the International Protocol criteria. Fifty-four patients over 30 years of age were studied and classified based on the International Protocol range. Blood pressure measurements at the wrist with the Samsung SBM-100A and Microlife BP 3BU1-5 were compared with the results obtained by two trained observers using a mercury sphygmomanometer. Nine sequential blood pressure measurements were taken. A total of 33 participants with randomly distributed arm circumferences were selected for both of the validation studies. During each validation study, 99 measurements were obtained for comparison from 33 participants. The first phase was performed on 15 participants and if the device passed this phase, 18 more participants were selected. Mean discrepancies and standard deviations of the device-sphygmomanometer were 0.9+/-9.2 and -2.7+/-9.3 mmHg for systolic blood pressure and -1.4+/-8.0 mmHg and 1.4+/-5.7 for diastolic blood pressure in the Samsung and Microlife study groups, respectively. The Samsung SBM-100A passed Phase 1 in 15 participants. Despite the fact that Microlife BP 3BU1-5 passed Phase 1 for diastolic pressure, it failed according to the systolic pressure criteria. Eighteen patients were added and Phase 2 was continued, in which Samsung SBM-100A failed to meet the criteria of Phases 2.1 and 2.2 for adults in systolic and diastolic blood pressure. It was found that the Microlife BP 3BU1-5 does not meet the criteria of either of Phases 2.1 and 2.2 for systolic blood pressure and Phase 2.2 for diastolic blood pressure. In this study, Samsung SBM

    The National centre for Radiotherapy and Nuclear Medicine at the Korle-bu Teaching Hospital in Ghana uses a Theratron Equinox 100 Cobalt-60 teletherapy machine that was commissioned in 2014 with a source activity of 370.4TBq. The prime objective of this research was to estimate the risk and probability of cancer induction to workers and also to evaluate the level of radiation safety at the facility. Data was collected by means of TLDs and personal dose records available between the periods February 2010 and April 2016. The results from 2010-2016 were used to compute the mean annual dose, mean annual collective dose as well as risk assessments using the ICRP 1990 and 2007 recommendations. Ambient dose rate measurements were also done using a Thermo electron survey meter. The Results showed that mean effective dose recorded from TLDs used in this research ranged from 0.08mSv-0.36mSv whiles dose records from 2010-2016 showed mean annual effective doses ranged between 0.23mSv-0.65mSv. Mean annual collective dose was 0.09 mSv. Annual cancer risk estimates also showed that workers probability of developing cancers had a mean value of 2.37 x 10"-"2±7.75 x 10"-"3 whiles risk of passing hereditary traits to offspring born after exposure showed a mean value 3.96 x 10"-"3± 1.29 x 10"-"3 according to the ICRP 1990 recommendations and ICRP 2007 showed that possibility of cancer induction to workers showed a mean value of 2.03 x 10"-"2±1.61 x 10"-"3. Mean annual dose rates did not exceed 14.8mSv/a,5mSv/a and 0.74mSv/a for the treatment room, control console room and the controlled area respectively. This shows that workers at the facility are not likely to exceed the recommended dose limit within a year while working at the facility. Ambient dose rates did not exceed 7.39μSv/hr, 2.80μSv/hr and 0.37μSv/hr for the treatment room, control console room and the controlled area respectively. These values obtained are below the recommended limit of 20μSv/hr. (au)

    Previous studies have shown an equivalent pharmacokinetic profile between four-times-daily (4QD) and once-daily (QD) administration of intra-venous (IV) BU, without increased toxicity. We assess the impact of a switch in IV BU from a 4QD to a QD schedule, in terms of health-care organization, staff working conditions, quality of care dispensed and perceived patient comfort. Clinicians, nurses and pharmacists from nine allogeneic transplantation units in five European countries were interviewed face to face. Overall perception of QD versus 4QD BU was very positive. Both administration schemes were evaluated to be equally efficaciousZ. QD BU was perceived to be safer and more convenient. Clinicians and nurses perceived that patient comfort was improved, due to fewer complications associated with repeated infusions, and avoiding night infusions associated with stress, anxiety and decreased quality of sleep. Switching from 4QD to QD BU had a significant impact on health-care organization, with a better integration in the overall management and usual timelines in the pharmacies and transplantation units. Time spent to prepare and administer BU was significantly reduced, leading to potential financial savings that merit further assessment and would be of particular interest in the current economic climate.

    In this study, water-n-BuOH mixed solvents were used to synthesize the ZnAl-layered double hydroxides (ZnAl-LDHs) via hydrothermal method. The XRD, FT-IR, SEM, ICP and CHN analyses revealed that the type of intercalated anions, the layer Zn/Al ratios, and morphologies of the LDHs depended on the ratio of V(water)/V(n-BuOH) in the mixed solvents. When the ratio of V(water)/V(n-BuOH) is 3 or 0.3, the as-prepared LDHs had 3D "silk flowers" (ZnAl-LDH-3) or "Sedimentary rock" morphology (ZnAl-LDH-0.3). Adsorption properties of dyes on calcined LDHs were studied. Compared with ZnAl-LDO-0.3 and ZnAl-LDO-w (calcined from the LDHs obtained in pure water), ZnAl-LDO-3 showed much better adsorption efficiency for anionic dyes thanks to its much larger BET-specific surface area. The sorption kinetics for dyes was appropriately described by the pseudo-second-order model and sorption isotherms can be fitted more satisfactorily by the Langmuir model. With the increasing concentrations of dyes from 10mg/L to 400mg/L, the maximum absorption capacities of ZnAl-LDO-3 were 1540mg/g (2.21mmol/g) for congo red, 1153mg/g (3.52mmol/g) for methyl orange and 390mg/g (0.63mmol/g) for active red (X-3B), respectively. The adsorption dyes onto the external surface is still the main mechanism for LDO adsorbents. The ZnAl-LDO-3 was a potential adsorbent for dyeing wastewater treatment. Copyright © 2017 Elsevier Inc.

    2013-08-12

    Metallocenes are a modern innovation in polyolefin catalysis research. Therefore, two supported metallocene catalysts-silica/MAO/(nBuCp)2ZrCl2 (Catalyst 1) and silica/nBuSnCl3/MAO/(nBuCp)2ZrCl2 (Catalyst 2), where MAO is methylaluminoxane-were synthesized, and subsequently used to prepare, without separate feeding of MAO, ethylene-1-hexene Copolymer 1 and Copolymer 2, respectively. Fouling-free copolymerization, catalyst kinetic stability and production of free-flowing polymer particles (replicating the catalyst particle size distribution) confirmed the occurrence of heterogeneous catalysis. The catalyst active center distribution was modeled by deconvoluting the measured molecular weight distribution and copolymer composition distribution. Five different active center types were predicted for each catalyst, which was corroborated by successive self-nucleation and annealing experiments, as well as by an extended X-ray absorption fine structure spectroscopy report published in the literature. Hence, metallocenes impregnated particularly on an MAO-pretreated support may be rightly envisioned to comprise an ensemble of isolated single sites that have varying coordination environments. This study shows how the active center distribution and the design of supported MAO anions affect copolymerization activity, polymerization mechanism and the resulting polymer microstructures. Catalyst 2 showed less copolymerization activity than Catalyst 1. Strong chain transfer and positive co-monomer effect-both by 1-hexene-were common. Each copolymer demonstrated vinyl, vinylidene and trans-vinylene end groups, and compositional heterogeneity. All these findings were explained, as appropriate, considering the modeled active center distribution, MAO cage structure repeat units, proposed catalyst surface chemistry, segregation effects and the literature that concerns and supports this study. While doing so, new insights were obtained. Additionally, future research, along the direction

    A series of pentapeptides, based on Bu-His(6)-DPhe(7)-Arg(8)-Trp(9)-Gly(10)-NH(2) and modified at the Arg(8) position, was prepared and pharmacologically characterized. Peptides containing either cyanoguanidine or acylguanidine, two substantially less basic arginine surrogates, were found to retain the agonist activity of the parent peptide at both hMC1R and hMC4R. This study unequivocally shows that the positive charge of Arg(8) is not essential for efficient interactions of our pentapeptide with both hMC1R and hMC4R.

    The imidazoline 2 binding site (I 2 BS), are thought to be expressed in glia, and implicated in the regulation of glial fibrillary acidic protein. A PET ligand for this target would be important for the investigation of neurodegenerative and neuroinflammatory diseases. 11 C-BU99008 has previously been identified as a putative PET radioligand. Here we present the first in vivo characterisation of this PET radioligand in humans and assess its test-retest reproducibility. Methods 14 healthy male volunteers underwent dynamic PET imaging with 11 C-BU99008 and arterial sampling. Six subjects were used to assess test-retest and eight were used in the pharmacological evaluation, undergoing a second, or third heterologous competition scan with the mixed I 2 BS/α 2 -adrenoceptor drug, idazoxan (n=8; 20, 40, 60 and 80mg) and the mixed irreversible MAO A/B inhibitor, isocarboxazid (n=4; 50mg), respectively. Regional time-activity data were generated from arterial plasma input functions corrected for metabolites using the most appropriate model to derive the outcome measure V T (regional total distribution volume). All image processing and kinetic analysis was performed in MIAKAT™ (www.miakat.org). Results Brain uptake of 11 C-BU99008 was good with reversible kinetics and a heterogeneous distribution consistent with known I 2 BS expression. Model selection criteria indicated that the 2-tissue-compartment was preferred. V T estimates were high in the striatum (113±20 mL·cm -3 ), medium in cortex frontal lobe (55±9 mL·cm -3 ) and low in the cerebellum (47±7 mL·cm -3 ). Test-retest reliability was found to be reasonable. The uptake was dose-dependently reduced by pre-treatment with idazoxan throughout the brain, with an average block across all regions of ~60% ( V T = ~30 mL·cm -3 ) at the highest dose (80 mg). The ED 50 for idazoxan was calculated as 33.1 mg. Uptake was not blocked by pre-treatment with the MAO inhibitor, isocarboxazid. Conclusions In summary, 11 C-BU

    The judicious design of methylaluminoxane (MAO) anions expands the scope for developing industrial metallocene catalysts. Therefore, the effects of MAO anion design on the backbone structure, melt behavior, and crystallization of ethylene−4-methyl-1-pentene (E−4M1P) copolymer were investigated. Ethylene was homopolymerized, as well as copolymerized with 4M1P, using (i) MAO anion A (unsupported [MAOCl2]−) premixed with dehydroxylated silica, (nBuCp)2ZrCl2, and Me2SiCl2; and (ii) MAO anion B (Si−O−Me2Si−[MAOCl2]−) supported with (nBuCp)2ZrCl2 on Me2SiCl2-functionalized silica. Unsupported Me2SiCl2, opposite to the supported analogue, acted as a co-chain transfer agent with 4M1P. The modeling of polyethylene melting and crystallization kinetics, including critical crystallite stability, produced insightful results. This study especially illustrates how branched polyethylene can be prepared from ethylene alone using particularly one metallocene-MAO ion pair, and how a compound, that functionalizes silica as well as terminates the chain, can synthesize ethylene−α-olefin copolymers with novel structures. Hence, it unfolds prospective future research niches in polyethyne systhesis. This article is protected by copyright. All rights reserved.

    Ultrasmall nanomolecules (<2 nm) such as Au 25 (SCH 2 CH 2 Ph) 18 , Au 38 (SCH 2 CH 2 Ph) 24 , and Au 144 (SCH 2 CH 2 Ph) 60 are well studied and can be prepared using established synthetic procedures. No such synthetic protocols that result in high yield products from commercially available starting materials exist for Au 36 (SPh-X) 24 . Here, we report a synthetic procedure for the large-scale synthesis of highly stable Au 36 (SPh-X) 24 with a yield of ∼42%. Au 36 (SPh-X) 24 was conveniently synthesized by using tert-butylbenzenethiol (HSPh-tBu, TBBT) as the ligand, giving a more stable product with better shelf life and higher yield than previously reported for making Au 36 (SPh) 24 from thiophenol (PhSH). The choice of thiol, solvent, and reaction conditions were modified for the optimization of the synthetic procedure. The purposes of this work are to (1) optimize the existing procedure to obtain stable product with better yield, (2) develop a scalable synthetic procedure, (3) demonstrate the superior stability of Au 36 (SPh-tBu) 24 when compared to Au 36 (SPh) 24 , and (4) demonstrate the reproducibility and robustness of the optimized synthetic procedure.

    The fludarabine (FLU)/melphalan (MEL) conditioning regimen containing FLU and high-dose MEL was analyzed in comparison with the BU/CY2 regimen to characterize oral mucositis (OM) and risk factors. OM incidence significantly varied between BU/CY2 and FLU/MEL (100 vs 78%, P=0.004), but the incidence of severe OM grades 3-4 WHO and kinetics of OM were fully comparable. Patients with OM persisting on day +21 had more acute GVHD (68 vs 32%, P=0.005), which tended to occur earlier than among those without such prolonged OM. Multivariate analysis showed significant dependency of acute GVHD on severity and prolonged duration of OM and significant correlation between OM severity and its prolonged duration. Body surface area-based dosing in the FLU/MEL regimen led to a wide range of MEL doses administered per kilogram body weight (2.5-5.2 mg/kg, median 3.5). In multivariate analysis, MEL dose per kilogram of body weight was found to be a significant predictor of OM incidence and severity. Female gender and lower body mass index were less important variables than the fact that the actual dose of MEL administered per kilogram of body weight was relatively high when the dosage was calculated on the basis of body surface area.

    Thin films of vanadium arsenide were deposited via the dual-source atmospheric pressure chemical vapour deposition reactions of VCl 4 or VOCl 3 with t BuAsH 2 . Using the vanadium precursor VCl 4 , films were deposited at substrate temperatures of 550–600 °C, which were black-gold in appearance and were found to be metal-rich with high levels of chlorine incorporation. The use of VOCl 3 as the vanadium source resulted in films being deposited between 450 and 600 °C and, unlike when using VCl 4 , were silver in appearance. The films deposited using VOCl 3 demonstrated vanadium to arsenic ratios close to 1:1, and negligible chlorine incorporation. Films deposited using either vanadium precursor were identified as VAs using powder X-ray diffraction and possessed borderline metallic/semiconductor resistivities. - Highlights: • Formation of VAs films via atmospheric pressure chemical vapour deposition. • Films formed using VCl 4 or VOCl 3 and t BuAsH 2 . • Powder X-ray diffraction showed that crystalline VAs films were deposited. • Films from VOCl 3 had a V:As ratio close to 1 with negligible Cl incorporation. • Films were silver and possessed borderline metallic/semiconductor resistivities

    Svenson, Eric Johan

    Participants on the Invincible America Assembly in Fairfield, Iowa, and neighboring Maharishi Vedic City, Iowa, practicing Maharishi Transcendental Meditation(TM) (TM) and the TM-Sidhi(TM) programs in large groups, submitted written experiences that they had had during, and in some cases shortly after, their daily practice of the TM and TM-Sidhi programs. Participants were instructed to include in their written experiences only what they observed and to leave out interpretation and analysis. These experiences were then read by the author and compared with principles and phenomena of modern physics, particularly with quantum theory, astrophysics, quantum cosmology, and string theory as well as defining characteristics of higher states of consciousness as described by Maharishi Vedic Science. In all cases, particular principles or phenomena of physics and qualities of higher states of consciousness appeared qualitatively quite similar to the content of the given experience. These experiences are presented in an Appendix, in which the corresponding principles and phenomena of physics are also presented. These physics "commentaries" on the experiences were written largely in layman's terms, without equations, and, in nearly every case, with clear reference to the corresponding sections of the experiences to which a given principle appears to relate. An abundance of similarities were apparent between the subjective experiences during meditation and principles of modern physics. A theoretic framework for understanding these rich similarities may begin with Maharishi's theory of higher states of consciousness provided herein. We conclude that the consistency and richness of detail found in these abundant similarities warrants the further pursuit and development of such a framework.

  4. Promoting industrialisation

    International Nuclear Information System (INIS)

    Hayfield, F.

    1986-04-01

    When the first nuclear power programme is decided upon, automatically the country has to initiate in parallel a programme to modify or add to its current industrial structure and resources. The extent of this new industrialisation depends upon many factors which both, the Government and the Industries have to consider. The Government has a vital role which includes the setting up of the background against which the industrial promotion should take place and in many cases may have also to play an active role all along this programme. Equally, the existing industries have an important role so as to achieve the most efficient participation in the nuclear programme. Invariably the industrial promotional programme will incur a certain degree of transfer of technology, the extent depending on the policies adopted. For this technology transfer to take place efficiently, both the donor and the receiver have to recognise each other's legitimate ambitions and fears. The transfer of technology is a process having a high human content and both donor and receiver have to take this into account. This can be further complicated when there is a difference in culture between them. Technology transfer is carried out within a contractual and organisational framework which will identify the donor (licensor) and the receiver (licensee). This framework may take various forms from a simple cooperative agreement, through a joint-venture organisation right to a standard contract between two separate entities. Each arrangement has its advantages and drawbacks and requires investment of different degrees. One of the keys to a successful industrial promotion is having it carried out in a timely fashion which will be parallel with the nuclear power programme. Experience in some countries has shown the problems when the industrialisation is out of phase with the programme whilst in other cases this industrialisation was at a level and scale unjustified.

    An important part of a general quality assurance (QA) program for brachytherapy dosimetry is the source calibration because wide ranges of uncertainties are quoted by manufactures. This research is aimed at calibrating LDR 137 Cs brachytherapy source in the Korle-Bu Teaching Hospital by multiple-distance air kerma measurement technique using a specialized designed jig and a calibrated therapy ionization chamber. Specialized jig was fabricated with source holder positions and ionization chamber positions on the jig. Farmer type ionization chamber of volume 0.6cm 3 was used with and without build up cap. The results were validated using well type ionization chamber on channels on 1 and 5 taking into account decay correction. Air Kerma rates were determined at multiple distances between 8cm to 12cm from measured charges recorded by Max 4000 electrometer. The scatter dose relationship described by Ezzell [1992] was used to determine scattered radiation. The analytical method of determining air kerma calibration factor of 137 Cs described by Sharma et.al [2011] was used to determine beam quality correction factor for the 137 Cs. Beam attenuation was determined. Experimental data were compared with manufacturer's quoted source strength for verification. Well type ionization chamber results and experimental results on channel V1 and V5 deviated by 2.39% and 1.58% respectively. Experimental data deviated by 4.73% and 1.24% from theoretical data on channels V1 and V5 respectively. The mean of the experimental data deviated from the theoretical data by ±3.1% and from the well type measurements data by ±1.98%. The well type chamber results compared well with the experimental data. This is an indication that the method used for source calibration is a reliable alternative method of source calibration. The method used in this work has proven to be an efficient way of determining the actual source strength of the LDR brachytherapy 137 Cs source in Korle-Bu Radiotherapy Centre

    Hypertensive disorders in pregnancy are a leading cause of maternal and fetal morbidity worldwide. Raised blood pressure (BP) affects 10% of pregnancies worldwide, of which almost half develop pre-eclampsia. The proportion of pregnant women who have risk factors for pre-eclampsia (such as pre-existing hypertension, obesity and advanced maternal age) is increasing. Pre-eclampsia can manifest itself before women experience symptoms and can develop between antenatal visits. Incentives to improve early detection of gestational hypertensive disorders are therefore strong and self-monitoring of blood pressure (SMBP) in pregnancy might be one means to achieve this, whilst improving women's involvement in antenatal care. The Blood Pressure Self-Monitoring in Pregnancy (BuMP) study aimed to evaluate the feasibility and acceptability of SMBP in pregnancy. To understand women's experiences of SMBP during pregnancy, we undertook a qualitative study embedded within the BuMP observational feasibility study. Women who were at higher risk of developing hypertension and/or pre-eclampsia were invited to take part in a study using SMBP and also invited to take part in an interview. Semi-structured interviews were conducted at the women's homes in Oxfordshire and Birmingham with women who were self-monitoring their BP as part of the BuMP feasibility study in 2014. Interviews were conducted by a qualitative researcher and transcribed verbatim. A framework approach was used for analysis. Fifteen women agreed to be interviewed. Respondents reported general willingness to engage with monitoring their own BP, feeling that it could reduce anxiety around their health during pregnancy, particularly if they had previous experience of raised BP or pre-eclampsia. They felt able to incorporate self-monitoring into their weekly routines, although this was harder post-partum. Self-monitoring of BP made them more aware of the risks of hypertension and pre-eclampsia in pregnancy. Feelings of

    Full Text Available The volatile compounds found in virgin olive oil, mainly C6 and C5 volatile compounds biogenerated from polyunsaturated fatty acids through the lipoxygenase pathway, are responsible for their particular aroma. The composition of volatile compounds in olive oil depends on the cultivar, the ripening degree of the fruits and processing conditions. Among many different autochthonous cultivars in Istria (Croatia, some of the most prevalent are Buža, Črna and Rosinjola. The volatiles and sensory characteristics of their monovarietal virgin olive oil are little known. Therefore, fruits from these three cultivars were handpicked at the same ripening degree and processed under the same conditions. Quantitative descriptive sensory analysis of monovarietal virgin olive oil was carried out by the panel. Volatile composition was evaluated by headspace solid phase microextraction-gas chromatography, previously optimized and validated. The main parameters affecting effectiveness, time and temperature of extraction were optimized. The extraction procedure showed detection and quantification limits, as well as linear ranges adequate for the analysis of selected volatile compounds. Good precision was obtained both in terms of intra-day repeatability (relative standard deviations generally lower than 7 % and inter-day precision. The tested types of monovarietal olive oil showed different volatile profiles, although E-2-hexenal was the main compound in all samples. Buža oil was the richest in total C6 and C5 volatile compounds. The results show that the most important contributors to the olive oil aroma (odour activity value >1.0 were 1-penten-3-one, E-2-hexenal, hexanal, hexanol, Z-3-hexen-1-ol and Z-2-penten-1-ol. These chemical findings were compared with those provided by the panel test. Buža had the highest intensity of sensory characteristic 'other ripe fruits' and Rosinjola had the highest intensity of sensory characteristic 'bitter'. All results show

    Two catalysts, denoted as catalyst 1 [silica/MAO/(nBuCp) 2ZrCl2] and catalyst 2 [silica/nBuSnCl 3/MAO/(nBuCp)2ZrCl2] were synthesized and subsequently used to prepare, without separate feeding of methylaluminoxane (MAO), ethylene homopolymer 1 and homopolymer 2, respectively, and ethylene-1-hexene copolymer 1 and copolymer 2, respectively. Gel permeation chromatography (GPC), Crystaf, differential scanning calorimetry (DSC) [conventional and successive self-nucleation and annealing (SSA)], and 13C nuclear magnetic resonance (NMR) polymer characterization results were used, as appropriate, to model the catalyst active-center distribution, ethylene sequence (equilibrium crystal) distribution, and lamellar thickness distribution (both continuous and discrete). Five different types of active centers were predicted in each catalyst, as corroborated by the SSA experiments and complemented by an extended X-ray absorption fine structure (EXAFS) report published in the literature. 13C NMR spectroscopy also supported this active-center multiplicity. Models combined with experiments effectively illustrated how and why the active-center distribution and the variance in the design of the supported MAO anion, having different electronic and steric effects and coordination environments, influence the concerned copolymerization mechanism and polymer properties, including inter- and intrachain compositional heterogeneity and thermal behaviors. Copolymerization occurred according to the first-order Markovian terminal model, producing fairly random copolymers with minor skewedness toward blocky character. For each copolymer, the theoretical most probable ethylene sequences, nE MPDSC-GT and n E MPNMR-Flory, as well as the weight-average lamellar thicknesses, Lwav DSC-GT and Lwav SSA DSC, were found to be comparable. To the best of our knowledge, such a match has not previously been reported. The percentage crystallinities of the homo- and copolymers increased linearly as a function of

    2013-06-01

    This research was carried out to investigate and compare the real-time and pre-plan implant at the Radiotherapy Department of the Korle Bu Teaching Hospital, Ghana. Prowess Panther 4.5 treatment planning system and variseed 7.2 software were used for pre-plan and real-time implant respectively. The study was conducted for eighty three (83) patients treated for prostate cancer through real-time implant brachytherapy between september, 2008 to April, 2013. Thirty one patients (31) patients whose ultrasound images were available were selected for the pre-plan study. The slices of ultrasound images were re-drawn on transparent A-4 sheets and later on scanned, contoured and registered in the treatment planning system (prowess 4.5). After planning, the volume to be implanted, total number of needles, seeds and the total activity of the source were displayed. Comparison was done withe the pre-plan and real-time implant. In both cases the variation was below 5% as recommended in dosimetry. About 30% - 40% of the imported seeds were left un-used due to over-estimation of seeds ordered from the manufacturer (BARD Company-USA). Hence this work (pre-plan) aims to solve this problem. The comparison for dosimetric parameters was assessed for prostate, urethra and rectum as (V 95%, V 100%, V 150%, D90Gy, D90%), (D90Gy, D90%, D30Gy, D30% ) and (V 100%, D30Gy and D30%) respectively and the variation were within the limit of ± 5%. Comparison of dosimetric values for this work were done with other institutions, like Karolinska university hospital, Sweden, The institute of Curie/ hospital Cochin Group Paris-France and European recommendations. The values reported at Korle - Bu teaching hospital (this work) were in good agreement with the international guidelines. (au)

  18. Phosphazene-promoted metal-free ring-opening polymerization of ethylene oxide initiated by carboxylic acid

    KAUST Repository

    Zhao, Junpeng

    2014-03-11

    The effectiveness of carboxylic acid as initiator for the anionic ring-opening polymerization of ethylene oxide was investigated with a strong phosphazene base (t-BuP4) used as promoter. Kinetic study showed an induction period, i.e., transformation of carboxylic acid to hydroxyl ester, followed by slow chain growth together with simultaneous and fast end-group transesterification, which led to poly(ethylene oxide) (PEO) consisting of monoester (monohydroxyl), diester, and dihydroxyl species. An appropriate t-BuP4/acid ratio was proven to be essential to achieve better control over the polymerization and low dispersity of PEO. This work provides important information and enriches the toolbox for macromolecular and biomolecular engineering with protic initiating sites. © 2014 American Chemical Society.

  20. Cyclic adenosine 3',5'-monophosphate (cAMP) enhances cAMP-responsive element binding (CREB) protein phosphorylation and phospho-CREB interaction with the mouse steroidogenic acute regulatory protein gene promoter.

    Steroidogenic acute regulatory protein (StAR) transcription is regulated through cAMP-protein kinase A-dependent mechanisms that involve multiple transcription factors including the cAMP-responsive element binding protein (CREB) family members. Classically, binding of phosphorylated CREB to cis-acting cAMP-responsive elements (5'-TGACGTCA-3') within target gene promoters leads to recruitment of the coactivator CREB binding protein (CBP). Herein we examined the extent of CREB family member phosphorylation on protein-DNA interactions and CBP recruitment with the StAR promoter. Immunoblot analysis revealed that CREB, cAMP-responsive element modulator (CREM), and activating transcription factor (ATF)-1 are expressed in MA-10 mouse Leydig tumor cells, yet only CREB and ATF-1 are phosphorylated. (Bu)2cAMP treatment of MA-10 cells increased CREB phosphorylation approximately 2.3-fold within 30 min but did not change total nuclear CREB expression levels. Using DNA-affinity chromatography, we now show that CREB and ATF-1, but not CREM, interact with the StAR promoter, and this interaction is dependent on the activator protein-1 (AP-1) cis-acting element within the cAMP-responsive region. In addition, (Bu)2cAMP-treatment increased phosphorylated CREB (P-CREB) association with the StAR promoter but did not influence total CREB interaction. In vivo chromatin immunoprecipitation assays demonstrated CREB binding to the StAR proximal promoter is independent of (Bu)2cAMP-treatment, confirming our in vitro analysis. However, (Bu)2cAMP-treatment increased P-CREB and CBP interaction with the StAR promoter, demonstrating for the first time the physical role of P-CREB:DNA interactions in CBP recruitment to the StAR proximal promoter.

  5. Constituting objectivity: Transcendental perspectives on modern physics

    Science.gov (United States)

    Everett, Jonathan

    2012-05-01

    There is increasing interest in exploring Kantian approaches in the study of the history and philosophy of physics. The most well-known examples of this trend-Friedman's (2001), Ryckman's (2005) and DiSalle's (2006)-focus on Kantianism in the context of the development of the general theory of relativity. The edited collection Constituting Objectivity seeks to develop key Kantian insights-in the most part-in the context of later developments in physics: as well as discussing relativity the volume also provides Kantian interpretations of Bohr's development of quantum theory and continues to provide Kantian insight from later interpretations of quantum mechanics all the way through to considering noncommutative geometry and loop quantum gravity. The volume contains papers on a wide variety of subjects and offers an essential introduction to the breadth of Kantian trends in modern physics.

  9. Moduli of Riemann surfaces, transcendental aspects

    International Nuclear Information System (INIS)

    Hain, R.

    2000-01-01

    These notes are an informal introduction to moduli spaces of compact Riemann surfaces via complex analysis, topology and Hodge Theory. The prerequisites for the first lecture are just basic complex variables, basic Riemann surface theory up to at least the Riemann-Roch formula, and some algebraic topology, especially covering space theory. The first lecture covers moduli in genus 0 and genus 1 as these can be understood using relatively elementary methods, but illustrate many of the points which arise in higher genus. The notes cover more material than was covered in the lectures, and sometimes the order of topics in the notes differs from that in the lectures. We have seen in genus 1 case that M 1 is the quotient Γ 1 /X 1 of a contractible complex manifold X 1 = H by a discrete group Γ 1 = SL 2 (Z). The action of Γ 1 on X 1 is said to be virtually free - that is, Γ 1 has a finite index subgroup which acts (fixed point) freely on X 1 . In this section we will generalize this to all g >= 1 - we will sketch a proof that there is a contractible complex manifold Xg, called Teichmueller space, and a group Γ g , called the mapping class group, which acts virtually freely on X g . The moduli space of genus g compact Riemann surfaces is the quotient: M g = Γ g /X g . This will imply that M g has the structure of a complex analytic variety with finite quotient singularities. Teichmueller theory is a difficult and technical subject. Because of this, it is only possible to give an overview. In this lecture, we compute the orbifold Picard group of M g for all g >= 1. Recall that an orbifold line bundle over M g is a holomorphic line bundle L over Teichmueller space X g together with an action of the mapping class group Γ g on it such that the projection L → X g is Γ g -equivariant. An orbifold section of this line bundle is a holomorphic Γ g -equivariant section X g → L of L. This is easily seen to be equivalent to fixing a level l>= 3 and considering holomorphic line bundles over M g [l] with an Sp g (Z/lZ)-actionsuch that the projection is Sp g (Z/lZ)-equivariant. Working on M g [l] has the advantage that we can talk about algebraic line bundles more easily. An algebraic orbifold line bundle over M g is an algebraic line bundle over Mg[l] for some l equipped with an action of Sp g (Z/lZ) such that the projection to M g [l] is Sp g (Z/lZ) equivariant. A section of such a line bundle is simply an Sp g (Z/lZ)-equivariant section defined over M g [l]. Isomorphism of such orbifold line bundles is defined in the obvious way. Let Pic orb M g denote the group of isomorphisms classes of algebraic orbifold line bundles over M g . Our goal in this lecture is to compute this group. It is first useful to review some facts about the Picard group of a smooth projective variety

    2012-01-01

    This summer I have been working on an Army Deep Futures Model project named Themis. Themis is a JPL based modeling framework that anticipates possible future states for the world within the next 25 years. The goal of this framework is to determine the likelihood that the US Army will need to intervene on behalf of the US strategic interests. Key elements that are modeled within this tool include the world structure and major decisions that are made by key actors. Each actor makes decisions based on their goals and within the constraints of the structure of the system in which they are located. In my research I have focused primarily on the effects of structures upon the decision-making processes of the actors within them. This research is a natural extension of my major program at Georgetown University, where I am studying the International Political Economy and the structures that make it up. My basic goal for this summer project was to be a helpful asset to the Themis modeling team, with any research done or processes learned constituting a bonus.

    Full Text Available Although radiation therapy can be effective against cancer, potential damage to normal tissues limits the amount that can be safely administered. In central nervous system (CNS, radiation damage to normal tissues is presented, in part, as suppressed hippocampal neurogenesis and impaired cognitive functions. Mn porphyrin (MnP-based redox active drugs have demonstrated differential effects on cancer and normal tissues in experimental animals that lead to protection of normal tissues and radio- and chemo-sensitization of cancers. To test the efficacy of MnPs in CNS radioprotection, we first examined the tissue levels of three different MnPs – MnTE-2-PyP5+(MnE, MnTnHex-2-PyP5+(MnHex, and MnTnBuOE-2-PyP5+(MnBuOE. Nanomolar concentrations of MnHex and MnBuOE were detected in various brain regions after daily subcutaneous administration, and MnBuOE was well tolerated at a daily dose of 3 mg/kg. Administration of MnBuOE for one week before cranial irradiation and continued for one week afterwards supported production and long-term survival of newborn neurons in the hippocampal dentate gyrus. MnP-driven S-glutathionylation in cortex and hippocampus showed differential responses to MnP administration and radiation in these two brain regions. A better understanding of how preserved hippocampal neurogenesis correlates with cognitive functions following cranial irradiation will be helpful in designing better MnP-based radioprotection strategies.

    This work explores the reduction of 4,4'-bipyridine using two equivalents of the titanium(iii) complex Ti(N[(t)Bu]Ar)3 resulting in formation of a black, crystalline complex, (4,4'-bipy){Ti(N[(t)Bu]Ar)3}2, for which an X-ray structure determination is reported. The neutral, black, 4,4'-bipyridine-bridged bimetallic was found to be redox active, with mono- and di-anions being accessible electrochemically, and with the mono- and di-cations also being accessible chemically, and isolable, at least when using the weakly coordinating anion [B(C6F5)4](-) as the counter-ion. It proved possible to crystallize the salt [(4,4'-bipy){Ti(N[(t)Bu]Ar)3}2][B(C6F5)4]2 for a single-crystal X-ray structure investigation; in this instance it was revealed that the aromaticity of the 4,4'-bipyridine ligand, that had been disrupted upon reduction, had been regained. A rare cationic d(0) metal tris-amide complex, shown by X-ray crystallography to contain an intriguing pyramidal TiN3 core geometry, namely {Ti(N[(t)Bu]Ar)3}(+), could also be isolated when using [B(C6F5)4] as the essentially non-interacting counter-ion. This highly reactive cation should be considered as a potential intermediate in the plethora of reactions wherein Ti(N[(t)Bu]Ar)3 has been shown to effect the reduction of substrates including halogenated organic molecules, carbonyl compounds, organic nitriles, and metal complexes.

    2014-07-01

    Two different supported zirconocene, that is, bis(n-butylcyclopentadienyl) zirconium dichloride (nBuCp)2ZrCl2, catalysts were synthesized. Each catalyst was used to prepare one ethylene homopolymer and one ethylene-1-hexene copolymer. Catalyst active center multiplicity and polymer crystallization kinetics were modeled. Five separate active center types were predicted, which matched the successive self-nucleation and annealing (SSA) peak temperatures. The predicted crystallinity well matched the differential scanning calorimetric (DSC) values for a single Avrami-Erofeev index, which ranged between 2 and 3 for the polymers experimented. The estimated apparent crystallization activation energy Ea did not vary with cooling rates, relative crystallinity α, and crystallization time or temperature. Therefore, the concept of variable/instantaneous activation energy was not found to hold. Ea linearly increased with the weight average lamellar thickness Lwav DSC-GT; and for each homopolymer, it exceeded that of the corresponding copolymer. Higher Ea, hence slower crystallization, was identified as a pre-requisite to attain higher crystallinity. Crystallization parameters were correlated to polymer backbone parameters, which are influenced by catalyst active center multiplicity. © 2013 Taiwan Institute of Chemical Engineers.

    A theoretical study was carried out to re-evaluate the integrity of the biological shielding of 137 Cs brachytherapy unit at the Korle Bu Teaching Hospital (Ghana), and the results were verified by measurement of the dose rates at selected locations. The primary objective was to determine the current state of protection and safety of staff and the general public. Shielding design of the brachytherapy unit at the hospital was based on postulated workload and occupancy factors of the facility. The facility has been in existence for 12 y and has accumulated operational workload data that differs from the postulated one. The results show that despite the variation in actual and postulated workloads, the dose rates were below the reference values 0.5 mSv h -1 for public areas and 7.5 μSv h -1 for controlled areas. These values were in the range of 0.10-0.12 μSv h -1 for public areas and of 0.50-2.10 μSv h -1 for controlled areas. (authors)

  1. Ethylene homo- and copolymerization chain-transfers: A perspective from supported (n BuCp) 2 ZrCl 2 catalyst active centre distribution

    KAUST Repository

    Atiqullah, Muhammad

    2015-04-01

    Polymerization chain termination reactions and unsaturation of the polymer backbone end are related. Therefore, in this study, the parameters resulting from the modelling of the active centre distribution of the supported catalyst - silica/MAO/(nBuCp)2ZrCl2 - were applied to evaluate the active-centre-dependent ethylene homo- and copolymerization rates, as well as the corresponding chain termination rates. This approach, from a microkinetic mechanistic viewpoint, elucidates better the 1-hexene-induced positive comonomer effect and chain transfer phenomenon. The kinetic expressions, developed on the basis of the proposed polymerization mechanisms, illustrate how the active site type-dependent chain transfer phenomenon is influenced by the different apparent termination rate constants and momoner concentrations. The active centre-specific molecular weight M ni (for the above homo- and copolymer), as a function of chain transfer probability, p CTi, varied as follows: log (p C Ti) = log (mwru) - log (Mn i), where mw ru is the molecular weight of the repeat unit. The physical significance of this finding has been explained. The homo- and copolymer backbones showed all the three chain end unsaturations (vinyl, vinylidene, and trans-vinylene). The postulated polymerization mechanisms reveal the underlying polymer chemistry. The results of the present study will contribute to develop in future supported metallocene catalysts that will be useful to synthesize polyethylene precursors having varying chain end unsaturations, which can be eventually used to prepare functional polyethylenes.

    Radioisotopes are used in diagnosing primary and metastatic bone tumours because of the high sensitivity. Diagnosing bone tumours using technetium methylene diphosphonate (Tc-99m MDP) on 9 randomly selected whole-body bone scans have been demonstrated by clinical studies of patients for illustrative review. Upon satisfactory testing of the e.cam (R) Single Photon Emission Computed Tomography at the Nuclear Medicine Department (Korle-Bu Teaching Hospital), scans of patients provided essential physiologic information about the sites of bone lesions and prognosis as shown by sequential changes in tracer uptake. The bone scintigrams were classified either as normal or pathologic. Of the 197 patients (91 males and 106 females) who underwent radioactive whole-body scans in the year 2006, the peak age at bone tumour detection was between 51 and 60 years. From qualitative analyses of the reported cases, 144 patients were diagnosed with bone tumours, but ∼ 17 % were found to be primary, while ∼ 83 % were metastatic in nature. The observation confirmed other published data that bone tumours with origin in the cells of bone are not prevalent compared to tumours that metastasize from other parts of the body, such as breast, cervix and prostate. Breast, prostate and cervical cancers contributed respectively to 34 %, 19 % and 18 % of the bone tumour cases, but only 3 % were diagnosed with osteoporosis (a relatively rare type of bone disease).

    There is a high prevalence of gastro-duodenal disease in sub-Saharan Africa. Peptic ulcer disease in dyspeptic patients, 24.5%, was comparable to prevalence of gastro-duodenal disease among symptomatic individuals in developed countries (12 - 25%). Limited data exists regarding its associated risk factors despite accumulating evidence indicating that gastroduodenal disease is common in Ghana. This study investigates risk factors associated with gastro-duodenal disease at the Korle-Bu Teaching Hospital, Accra, Ghana. This study utilized a cross-sectional design to consecutively recruit patients referred with upper gastro-intestinal symptoms for endoscopy. The study questionnaire was administered to study participants. Helicobacter pylori infection was confirmed by rapid-urease examination at endoscopy. Of 242 patients sampled; 64 had duodenal ulcer, 66 gastric ulcer, 27gastric cancer and 64 non-ulcer dyspepsia. Nineteen (19) had duodenal and gastric ulcer while 2 had gastric ulcer and cancer. A third (32.6%) of patients had history of NSAID-use. H. pyloriwas associated with gastric ulcer (p=0.033) and duodenal ulcer (p=0.001). There was an increased prevalence of duodenal ulcer in H. pylori-infected patients taking NSAIDs, P=0.003. H. pylori was a major risk factor for peptic ulcer disease. However, NSAID-related gastro-duodenal injury has been shown to be common in H. pylori infected patients. It highlights the need for awareness of the adverse gastro-intestinal effects in a H. pylori endemic area.

    Lung function decline is a well-recognized complication following allogeneic SCT (allo-SCT). Reduced-intensity conditioning (RIC) and in vivo T-cell depletion by administration of antithymocyte globulin (ATG) may have a protective role in the occurrence of late pulmonary complications. This retrospective study reported the evolution of lung function parameters within the first 2 years after allo-SCT in a population receiving the same RIC regimen that included fludarabine and i.v. BU in combination with low-dose ATG. The median follow-up was 35.2 months. With a median age of 59 years at the time of transplant, at 2 years, the cumulative incidences of non-relapse mortality was as low as 9.7%. The cumulative incidence of relapse was 33%. At 2 years, the cumulative incidences of extensive chronic GVHD (cGVHD) and of pulmonary cGVHD were 23.1% and 1.9%, respectively. The cumulative incidences of airflow obstruction and restrictive pattern were 3.8% and 9.6%, respectively. Moreover, forced expiratory volume (FEV1), forced vital capacity (FVC) and FEV1/FVC ratio remained stable from baseline up to 2 years post transplantation (P=0.26, P=0.27 and P=0.07, respectively). These results correspond favorably with the results obtained with other RIC regimens not incorporating ATG, and suggest that ATG may have a protective pulmonary role after allo-SCT.

To ensure the consistency of quality, a reliable analytical method is required, therefore, we developed a liquid chromatography with tandem mass spectrometry (LC-MS/MS method for quantitative analysis of the major constituents in BYHWT. The herbal ingredients consisting of the cycloartane-type triterpene glycosides of astragaloside I, astragaloside II and astragaloside IV; isoflavones of formononetin, ononin calycosin, calycosin-7-O-β-d-glucoside; ligustilide and paeoniflorin were separated on a C18 column with gradient elution of methanol/10 mM ammonium acetate buffer–formic acid (100:0.1, v/v. This study was performed by a mass spectrometer using electrospray ionization (ESI with positive ionization ions monitored in the multiple reaction-monitoring (MRM mode. The linearity, accuracy, precision, limit of detection (LOD and lower limit of quantification (LLOQ were validated for this quantification method, and the sensitivity, reliability and reproducibility were all confirmed. The experiments provided a good method for analyzing BYHWT extracts. This study also quantitated the active components in various brands of commercially available products. The results indicated that the pharmaceutical industrial products of BYHWT exhibited considerable variation in their contents of the herbal compounds.

    Full Text Available Multiple organ systems, including the brain, which undergoes changes that may increase the risk of cognitive decline, are adversely affected by diabetes mellitus (DM. Here, we demonstrate that type 2 diabetes mellitus (T2DM db/db mice exhibited hippocampus-dependent memory impairment, which might associate with a reduction in dendritic spine density in the pyramidal neurons of brain, Aβ1-42 deposition in the prefrontal cortex (PFC and hippocampus, and a decreased expression of neurostructural proteins including microtubule-associated protein (MAP2, a marker of dendrites, and postsynaptic density 95 (PSD95, a marker of excitatory synapses. To investigate the effects of the ZiBuPiYin recipe (ZBPYR, a traditional Chinese medicine recipe, on diabetes-related cognitive decline (DACD, db/db mice received daily administration of ZBPYR over an experimental period of 6 weeks. We then confirmed that ZBPYR rescued learning and memory performance impairments, reversed dendritic spine loss, reduced Aβ1-42 deposition and restored the expression levels of MAP2 and PSD95. The present study also revealed that ZBPYR strengthened brain leptin and insulin signaling and inhibited GSK3β overactivity, which may be the potential mechanism or underlying targets of ZBPYR. These findings conclude that ZBPYR prevents DACD, most likely by improving dendritic spine density and attenuating brain leptin and insulin signaling pathway injury. Our findings provide further evidence for the effects of ZBPYR on DACD.

    Full Text Available Song Bu Li decoction (SBL is a traditional Uyghur medicinal herbal preparation, containing Nardostachyos Radix et Rhizoma. Recently, SBL is being used to treat neurological disorders (insomnia and neurasthenia and heart disorders (arrhythmia and palpitation. Although this herbal extract has been used for many years, there is no scientific basis about its effectiveness. Here, we aimed to evaluate the protective and differentiating activities of SBL in cultured PC12 cells. The pretreatment of SBL protected the cell against tBHP-induced cell death in a dose-dependent manner. In parallel, SBL suppressed intracellular reactive oxygen species (ROS formation. The transcriptional activity of antioxidant response element (ARE, as well as the key antioxidative stress proteins, was induced in dose-dependent manner by SBL in the cultures. In cultured PC12 cells, the expression of neurofilament, a protein marker for neuronal differentiation, was markedly induced by applied herbal extract. Moreover, the nerve growth factor- (NGF- induced neurite outgrowth in cultured PC12 cells was significantly potentiated by the cotreatment of SBL. In accord, the expression of neurofilament was increased in the treatment of SBL. These results therefore suggested a possible role of SBL by its effect on neuron differentiation and protection against oxidative stress.

    The non-donor-stabilized PSnP pincer-type stannylene Sn(NCH2PtBu2)2C6H4 (1) has been prepared by treating SnCl2 with Li2(NCH2PtBu2)2C6H4. All attempts to synthesize the analogous PSiP silylene by reduction of the (previously unknown) silanes SiCl2(NCH2PtBu2)2C6H4 (2), SiHCl(NCH2PtBu2)2C6H4 (3) and SiH(HMDS)(NCH2PtBu2)2C6H4 (4; HMDS = N(SiMe3)2) have been unsuccessful. The almost planar (excluding the tert-butyl groups) molecular structure of stannylene 1 (determined by X-ray crystallography) has been rationalized with the help of DFT calculations, which have shown that, in the series of diphosphanetetrylenes E(NCH2PtBu2)2C6H4 (E = C, Si, Ge, Sn), the most stable conformation of the compounds with E = Ge and Sn has both P atoms very close to the EN2C6H4 plane, near (interacting with) the E atom, whereas for the compounds with E = C and Si, both phosphane groups are located at one side of the EN2C6H4 plane and far away from the E atom. The size of the E atom and the strength of stabilizing donor-acceptor PE interactions (both increase on going down in group 14) are key factors in determining the molecular structures of these diphosphanetetrylenes. The syntheses of the chloridostannyl complexes [Rh{κ2Sn,P-SnCl(NCH2PtBu2)2C6H4}(η4-cod)] (5), [RuCl{κ2Sn,P-SnCl(NCH2PtBu2)2C6H4}(η6-cym)] (6) and [IrCl{κ2Sn,P-SnCl(NCH2PtBu2)2C6H4}(η5-C5Me5)] (7) have demonstrated the tendency of stannylene 1 to insert its Sn atom into M-Cl bonds of transition metal complexes and the preference of the resulting PSnP chloridostannyl group to act as a κ2Sn,P-chelating ligand, maintaining an uncoordinated phosphane fragment. X-ray diffraction data (of 6), 31P{1H} NMR data (of 5-7) and DFT calculations (on 6) are consistent with the existence of a weak PSn interaction involving the non-coordinated P atom of complexes 5-7, similar to that found in stannylene 1.

    The syntheses and full characterization of nickel hydrides containing the PCP "pincer"-type ligand, where PCP = 2,6-C(6)H(3)(CH(2)PR(2))(2) (R = tBu, cHex, and iPr), are reported. These Ni-H complexes are prepared by the conversion of ((R)PCP)NiCl precursors into the corresponding nickel hydrides by use of appropriate hydride donors. Surprisingly, although the ((R)PCP)NiCl precursors are quite similar chemically, the conversions to the hydrides were not straightforward and required different hydride reagents to provide analytically pure products. While NaBH(4) was effective in the preparation of pure ((tBu)PCP)NiH, Super-Hydride solution (LiEt(3)BH in THF) was required to prepare either ((cHex)PCP)NiH or ((iPr)PCP)NiH. Attempts to prepare a Ni-H from ((Ph)PCP)NiCl with a variety of hydride reagents yielded only the free ligand as an identifiable product. Two of the derivatives, tBu and cHex, have also been subjected to single crystal X-ray analysis. The solid-state structures each showed a classic, near-square planar arrangement for Ni in which the PCP ligand occupied three meridional ligand points with the Ni-H trans to the Ni-C bond. The resulting Ni-H bond lengths were 1.42(3) and 1.55(2) A for the tBu and cHex derivatives, respectively.

    This paper presents the results of three dimensional sequence stratigraphic forward modelling of the Aptian age Shu'aiba Formation from Abu Dhabi, United Arab Emirates (UAE). The Shu'aiba Formation lies within the uppermost part of the Lower Cretaceous Thamama Group and forms one of the most prolific hydrocarbon reservoir intervals of the Middle East with production dating back to the 1960's. The Shu'aiba Formation developed as a series of laterally-extensive shallow-water carbonate platforms in an epeiric sea that extended over the northern margin of the African-Arabian Plate. This shallow sea was bounded by the Arabian Shield to the west and the passive margin with the Neo-Tethys Ocean towards the north and east (Droste, 2010). The exposed Arabian Shield acted as a source of siliciclastic sediments to westernmost regions, however, more offshore areas were dominated by shallow-water carbonate deposition. Carbonate production was variously dominated by Lithocodium-Baccinella, orbitolinid foraminifera and rudist bivalves depending on local conditions. While there have been numerous studies of this important stratigraphic interval (for examples see van Buchem et al., 2010), there has been little attempt to simulate the sequence stratigraphic development of the formation. During the present study modelling was undertaken utilising the CARBONATE-3D stratigraphic forward modelling software (Warrlich et al., 2008; Warrlich et al., 2002)) thus allowing for the control of a diverse range of internal and external parameters on carbonate sequence development. This study focuses on platform development in the onshore Bu Hasa Field - the first giant oilfield to produce from the Shu'aiba Formation in Abu Dhabi. The carbonates of the Bu Hasa field were deposited on the southwest slope of the intra-shelf Bab Basin, siliciclastic content is minor. Initially these carbonates were algal dominated with rudist mounds becoming increasingly important over time (Alsharhan, 1987

    Maternal obesity in pregnancy has been linked with increased risk of pregnancy induced hypertension (PIH). In some tertiary referral hospitals in Ghana, PIH is the leading cause of institutional maternal mortality. To evaluate blood pressure changes during pregnancy amongst different body mass index (BMI) groups and how this relates to the risk of developing PIH. Women who had a dating ultrasound before 20 weeks gestation and registering for antenatal care at the Korle-Bu Teaching Hospital in Accra, between February and December 2013 and met the inclusion criteria were recruited into a cohort study. BMI was assessed at baseline. Blood pressure measurements were taken at (±2) 24, 28 and 36 weeks. Primary outcome measure of interest during follow-up was a diagnosis of PIH at these points. BP changes during follow up at the three points were measured. Descriptive analysis of baseline factors was carried out and compared for the BMI groups. Relative risk (RR) of PIH was estimated at 95% confidence interval. Mean (SD) age for the 361 women was 30.9 (4.8) years. Incidence of PIH amongst the cohort was 10.5% (95% CI: 7.45% - 14.45%) and 40.4% and 33.0% of them were overweight and obese respectively at baseline. Pregnant women who were obese at baseline had a three-fold increased risk of PIH compared to those with normal BMI [RR = 3.01 (1.06-8.52), p = 0.04]. Obese women have a significantly increased risk of PIH. Women should be screened at booking for obesity status. Antenatal protocols should have interventions for prevention or early detection of obesity and management of obesity to improve outcomes.

    Colorectal cancer remains one of the leading causes of cancer death worldwide. Traditional Chinese Medicine (TCM) has played a positive role in colorectal cancer treatment. There is a great need to establish effective herbal formula for colorectal cancer treatment. Based on TCM principles and clinical practices, we have established an eight herbs composed formula for colorectal cancer treatment, which is Teng-Long-Bu-Zhong-Tang (TLBZT). We have demonstrated the anticancer effects of TLBZT against colorectal carcinoma in vitro. In present study, we evaluated the anticancer potential of TLBZT, used alone or in combination with low dose of 5-Fluorouracil (5-Fu), in CT26 colon carcinoma in vivo. CT26 colon carcinoma was established in BALB/c mice and treated with TLBZT, 5-Fu, or TLBZT plus 5-Fu. The tumor volumes were observed. Apoptosis was detected by TUNEL assay. Caspases activities were detected by colorimetric assay. Cell senescence was indentified by senescence β-galactosidase staining. Gene expression and angiogenesis was observed by immunohistochemistry or western blot. TLBZT significantly inhibited CT26 colon carcinoma growth. TLBZT elicited apoptosis in CT26 colon carcinoma, accompanied by Caspase-3, 8, and 9 activation and PARP cleavage, and downregulation of XIAP and Survivin. TLBZT also induced cell senescence in CT26 colon carcinoma, with concomitant upregulation of p16 and p21 and downregulation of RB phosphorylation. In addition, angiogenesis and VEGF expression in CT26 colon carcinoma was significantly inhibited by TLBZT treatment. Furthermore, TLBZT significantly enhanced anticancer effects of 5-Fu in CT26 colon carcinoma. TLBZT exhibited significantly anticancer effect, and enhanced the effects of 5-Fu in CT26 colon carcinoma, which may correlate with induction of apoptosis and cell senescence, and angiogenesis inhibition. The present study provides new insight into TCM approaches for colon cancer treatment that are worth of further study.

  3. Fixed-Node Diffusion Quantum Monte Carlo Method on Dissociation Energies and Their Trends for R-X Bonds (R = Me, Et, i-Pr, t-Bu).

    Achieving both bond dissociation energies (BDEs) and their trends for the R-X bonds with R = Me, Et, i-Pr, and t-Bu reliably is nontrivial. Density functional theory (DFT) methods with traditional exchange-correlation functionals usually have large error on both the BDEs and their trends. The M06-2X functional gives rise to reliable BDEs, but the relative BDEs are determined not as accurately. More demanding approaches such as some double-hybrid functionals, for example, G4 and CCSD(T), are generally required to achieve the BDEs and their trends reliably. The fixed-node diffusion quantum Monte Carlo method (FN-DMC) is employed to calculated BDEs of these R-X bonds with X = H, CH 3 , OCH 3 , OH, and F in this work. The single Slater-Jastrow wave function is adopted as trial wave function, and pseudopotentials (PPs) developed for quantum Monte Carlo calculations are chosen. Error of these PPs is modest in wave function methods, while it is more pronounced in DFT calculations. Our results show that accuracy of BDEs with FN-DMC is similar to that of M06-2X and G4, and trends in BDEs are calculated more reliably than M06-2X. Both BDEs and trends in BDEs of these bonds are reproduced reasonably with FN-DMC. FN-DMC using PPs can thus be applied to BDEs and their trends of similar chemical bonds in larger molecules reliably and provide valuable information on properties of these molecules.

    2014-07-01

    Internal dosimetry deals with the measurement of the radiation dose absorbed internally by an organ after the administration of isotopes for diagnosis and treatment. In the present study radiation absorbed dose has been calculated for technetium-99m methylene diphosphonate (Tc-99m MDP) which is used frequently for bone scan in Korle-Bu teaching hospital nuclear medicine department. In these cases a small amount of isotopes are accumulated in kidney, urinary bladder etc. Study on sixty-five patients undergoing bone scans has been performed quantitatively using e.soft software. The Tc-99m MDP doses were administered to the patients with activity ranging from 377.4 to 932.4 MBq depending on their weights, and were then scanned with an installed e.Cam SPECT system. A 256 × 1024 matrix size was used in acquiring the bone scans. Also the scans of five volunteer patients at three different times (1 hour, 2 hour and 3 hour after injection) were used to determine the residence time in the bladder and kidney. To determine the amount of activity in patient kidney and urinary bladder, conjugate view method was applied on images information. MIRD equation and OLINDA/EXM software were then used to estimate absorbed dose in different organs of patients. The absorbed value obtained from the two methods were compared. The activity in patient’s left kidney, right kidney and urinary bladder undergoing bone scan three hours after injection of Tc-99m were 1.52±0.48 MBq, 1.52±0.44 MBq 4.88±3.11MBq respectively. The residence time for the kidney and urinary bladder were 0.128±0.043 hour and 1.099±0.330 hour respectively. The absorbed dose per unit of injected activity (mGy/MBq) for bladder, kidneys, liver, lungs, red marrow, ovaries, pancreas, skin and spleen were calculated for the male and the female patients using the two methods. The absorbed dose values obtained from the two methods were compared. In the study for absorbed dose calculation, MIRD equation is in agreement with

Dual-energy X-ray absorptiometry was performed to analyze the bone mineral density, and histomorphometric analysis was performed to measure the parameters related to bone metabolism. Calcein labeling was performed to detect bone formation. The uteruses from the mice were weighed, and the histomorphometry was analyzed. Drug-derived serum was prepared to assess the 17-β-estradiol concentration via enzyme immunoassay.Results: BSNXD administration ameliorated the osteoporotic phenotype of OVX mice, as evidenced by an increase in the bone mineral density and bone volume; these effects could not be abolished by the administration of the aromatase inhibitor letrozole. Moreover, BSNXD had no effect on the serum estrogen concentration or uterus.Conclusion: These results suggest that BSNXD has ameliorating effects on bone loss due to estrogen deprivation without affecting the peripheral blood estrogen concentration or the uterus in OVX mice.

    The concept of radiation promotion was proposed in this study. The proposal of this concept was dependent upon stimulation in growth weight of survived chicks when fertile eggs were exposed to 60 Co gamma radiation. It was found that female chick (Promotive Sex) responded to this proposal concept rather than the male. Moreover, the dose level of 640 rads was found to be the Promotive Dose. It is important before applying ionizing radiation as a growth promotive to take into consideration whether you want increasing egg or meat production, as meat promotion in layers breed is bound to decrease egg production.

    Full Text Available Mercedes Pinto’s itinerary took her from the Canary Islands, where she was born, to Mexico, after a passage through Uruguay. She first met success through her writings and cultural activities, and was then forgotten. However, her book –published in Montevideo in 1926– was adapted for the cinema by Luis Buñuel in 1952, and the film gave new life to this autobiographical “novel” He. If self-fiction prevails in the literary work, with the clear commitment of a feminist who takes a stand in favour of freedom –the freedom to divorce in that case–, in Buñuel’s Mexican film the study of the clinical case of paranoia acquires a new form of complexity. The attack on a parasitic bourgeoisie is united to the subversion of the melodramatic genre, with a false happy end which distorts established codes and lets the principle of doubt impose itself. In the same way the exploration of sexual roles, heir to the surrealistic trend, is devoid of any manichean simplification and stands out as a fascinating object for any hermeneutic approach.Mercedes Pinto, cuya trayectoria se desarrolló desde Canarias, su tierra de nacimiento, hasta México, pasando por Uruguay, conoció el éxito por sus escritos y actividades culturales y luego quedó sumida en el olvido.

Al ataque a una burguesía parasitaria se une una subversión del género del melodrama, cuyo falso final feliz pervierte los códigos establecidos, dejando que se imponga el principio de duda.

  18. Ab initio dynamics trajectory study of the heterolytic cleavage of H2 by a Lewis acid [B(C6F5)3] and a Lewis base [P(tBu)3

    Activation of H2 by a "frustrated Lewis pair" (FLP) composed of B(C6F5)3 and P(tBu)3 species has been explored with high level direct ab initio molecular dynamics (AIMD) simulations at finite temperature (T = 300 K) in gas phase. The initial geometrical conditions for the AIMD trajectory calculations, i.e., the near attack conformations of FLP + H2, were devised using the host-guest model in which suitable FLP conformations were obtained from the dynamics of the B(C6F5)3/P(tBu)3 pair in gas phase. AIMD trajectory calculations yielded microscopic insight into effects which originate from nuclear motion in the reacting complex, e.g., the alternating compression/elongation of the boron-phosphorous distance and the change of the pyramidality of boron in B(C6F5)3. The ensemble averaged trajectory analysis has been compared with the minimum energy path (MEP) description of the reaction. Similar to MEP, AIMD shows that an attack of the acid/base pair on the H-H bond gives rise to the polarization of the H2 molecule and as a consequence generates a large dipole moment of the reacting complex. The MEP and AIMD portrayals of the reaction are fundamentally different in terms of the magnitude of the motion of nuclei in B(C6F5)3 and P(tBu)3 during the H2 cleavage. In the AIMD trajectory simulations, geometries of B(C6F5)3 and P(tBu)3 appear as nearly "frozen" on the short time scale of the H2 cleavage. This is contrary to the MEP picture. Several of the concepts which arise from this work, e.g., separation of time scales of nuclear motion and the time-dependence of the donor-acceptor interactions in the reacting complex, are important for the understanding of chemical reactivity and catalysis.

  19. Adverse events and adherence to HIV post-exposure prophylaxis: a cohort study at the Korle-Bu Teaching Hospital in Accra, Ghana.

    There is strong evidence that post-exposure prophylaxis (PEP) with antiretroviral drugs in the timely management of occupational exposures sustained by healthcare workers decreases the risk of HIV infection and PEP is now widely used. Antiretroviral drugs have well documented toxicities and produce adverse events in patients living with HIV/AIDS. In the era of "highly active antiretroviral therapy", non-adherence to treatment has been closely linked to the occurrence of adverse events in HIV patients and this ultimately influences treatment success but the influence of adverse events on adherence during PEP is less well studied. Following the introduction of a HIV post-exposure prophylaxis program in the Korle-Bu Teaching Hospital in January 2005, the incidence of adverse events and adherence were documented in occupationally-exposed healthcare workers (HCWs) and healthcare students (HCSs). Cohort event monitoring was used in following-up on exposed HCWs/HCSs for the two study outcomes; adverse events and adherence. All adverse events reported were grouped by MedDRA system organ classification and then by preferred term according to prophylaxis regimen. Adherence was determined by the completion of prophylaxis schedule. Cox proportional regression analysis was applied to determine the factors associated with the cohort study outcomes. Differences in frequencies were tested using the Chi square test and p < 0.05 was considered statistically significant. A total of 228 exposed HCWs/HCSs were followed up during the study, made up of 101 exposed HCWs/HCSs administered lamivudine/zidovudine (3TC/AZT) for 3 days; 75 exposed HCWs/HCSs administered lamivudine/zidovudine (3TC/AZT) for 28 days; and 52 exposed HCWs/HCSs administered lamivudine/zidovudine/lopinavir-ritonavir (3TC/AZT/LPV-RTV) for 28 days. The frequency of adverse events was 28% (n = 28) in exposed HCWs/HCSs administered 3TC/AZT for 3 days, 91% (n = 68) in exposed HCWs/HCSs administered 3TC/AZT for

  1. SPORT PROMOTION STRATEGIES

    Directory of Open Access Journals (Sweden)

    Alexandru Lucian MIHAI

    2013-10-01

    Full Text Available In sport marketing, the word promotion covers a range of interrelated activities. All of these activities are designed to attract attention, stimulate the interest and awareness of consumers, and of course, encourage them to purchase a sport product. Promotion is about communicating with and educating consumers. The purpose of a sport promotional strategy is to build brand loyalty and product credibility, develop image, and position the brand. A promotional strategy is similar to a marketing strategy, but the promotional strategy seeks short-term objectives, both direct and indirect. Promotional objectives usually include increased sales, stimulate impulse buying, raise customer traffic, and present and reinforce image. It also provides information about products and services, publicizes new stores or websites, and creates and enhances customer satisfaction.

    Full Text Available Objective: to unravel some theoretical and factual elements required to implement more effective health promotion strategies and practices in the field of health services whilst following the great challenges that globalization has imposed on the health systems, which are inevitably expressed in the local context (glocalization. Methodology: a narrative review taking into account the concepts of globalization and health promotion in relation to health determinants. The authors approach some courses of action and strategies for health promotion based on the social principles and universal values that guide health promotion, health service reorientation and primary healthcare, empowerment, social participation, and inter-sectoral and social mobilization. Discussion: the discussion focuses on the redirection of health promotion services in relation to the wave of health reforms that has spread throughout the world under the neoliberal rule. The author also discusses health promotion, its ineffectiveness, and the quest for renewal. Likewise, the author sets priorities for health promotion in relation to social determinants. Conclusion: the current global order, in terms of international relations, is not consistent with the ethical principles of health promotion. In this paper, the author advocates for the implementation of actions to change the social and physical life conditions of people based on changes in the use of power in society and the appropriate practice of politics in the context of globalization in order to achieve the effectiveness of the actions of health promotion.

En se réclamant de l’allégorie biblique de l’ange mortifère (Todesengel, ils esquissent une société en rupture avec la conception traditionnelle. Ce portrait d’une société que l’on pourrait qualifier de « post-civilisée » invite à repenser, à partir des deux œuvres fictionnelles, le conflit social qui résulte d’une remise en question radicale des normes sociales de l’Occident.Zivilisiertheit und Barbarei bilden einen gemeinsamen Nexus.

    The Ni(I) hydrogen oxidation catalyst [Ni(P(Cy)2N(tBu)2)2](+) (1(+); P(Cy)2N(tBu)2 = 1,5-di(tert-butyl)-3,7-dicyclohexyl-1,5-diaza-3,7-diphosphacyclooctane) has been studied using a combination of electron paramagnetic resonance (EPR) techniques (X-, Q-, and D-band, electron-nuclear double resonance, hyperfine sublevel correlation spectroscopy), X-ray crystallography, and density functional theory (DFT) calculations. Crystallographic and DFT studies indicate that the molecular structure of 1(+) is highly symmetrical. EPR spectroscopy has allowed determination of the electronic g tensor and the spin density distribution on the ligands, and revealed that the Ni(I) center does not interact strongly with the potentially coordinating solvents acetonitrile and butyronitrile. The EPR spectra and magnetic parameters of 1(+) are found to be distinctly different from those for the related compound [Ni(P(Ph)2N(Ph)2)2](+) (4(+)). One significant contributor to these differences is that the molecular structure of 4(+) is unsymmetrical, unlike that of 1(+). DFT calculations on derivatives in which the R and R' groups are systematically varied have allowed elucidation of structure/substituent relationships and their corresponding influence on the magnetic resonance parameters.

    We report the syntheses, X-ray structures, and reductive electrochemistry of the Fe(II) complexes [(dmgBF(2))(2)Fe(MeCN)(2)] (1; dmg = dimethylglyoxime, MeCN = acetonitrile) and [(dmgBF(2))Fe((t)Bu(i)NC)(2)] (2; (t)Bu(i)NC = tert-butylisocyanide). The reaction of 1 with Na/Hg amalgam led to isolation and the X-ray structure of [(dmgBF(2))(2)Fe(glyIm)] (3; glyIm = glyimine), wherein the (dmgBF(2))(2) macrocyclic frame is bent to accommodate the binding of a bidentate apical ligand. We also report the X-ray structure of a rare mixed-valence Fe(4) cluster with supporting dmg-type ligands. In the structure of [(dmg(2)BF(2))(3)Fe(3)((1)/(2)dmg)(3)Fe(O)(6)] (4), the (dmgBF(2))(2) macrocycle has been cleaved, eliminating BF(2) groups. Density functional theory calculations and electron paramagnetic resonance data are in accordance with a central Fe(III) ion surrounded by three formally Fe(II)dmg(2)BF(2) units.

    Full Text Available Cytochrome P450 2C19 (CYP2C19 is an important drug-metabolizing enzyme (DME, which is responsible for the biotransformation of several kinds of drugs such as proton pump inhibitors, platelet aggregation inhibitors and antidepressants. Previous studies showed that Buchang NaoXinTong capsules (NXT increased the CYP2C19 metabolic activity in vitro and enhanced the antiplatelet effect of clopidogrel in vivo. However, the underlying molecular mechanism remained unclear. In the present study, we examined whether Pregnane X receptor (PXR plays a role in NXT-mediated regulation of CYP2C19 expression.We applied luciferase assays, real-time quantitative PCR (qPCR, Western blotting and cell-based analysis of metabolic activity experiments to investigate the NXT regulatory effects on the CYP2C19 promoter activity, the mRNA/ protein expression and the metabolic activity.Our results demonstrated that NXT significantly increased the CYP2C19 promoter activity when co-transfected with PXR in HepG2 cells. Mutations in PXR responsive element abolished the NXT inductive effects on the CYP2C19 promoter transcription. Additionally, NXT incubation (150 and 250μg/mL also markedly up-regulated endogenous CYP2C19 mRNA and protein levels in PXR-transfected HepG2 cells. Correspondingly, NXT leaded to a significant enhancement of the CYP2C19 catalytic activity in PXR-transfected HepG2 cells.In summary, this is the first study to suggest that NXT could induce CYP2C19 expression via PXR activation.

    A second iteration of a sirolimus-eluting stent (SES) that has a biodegradable PLGA polymer coating with an electrografting base layer on a thin-strut (80 µm) cobalt-chromium platform (BuMA Supreme; SINOMED, Tianjin, China) has been developed. This first-in-man trial aimed to assess the efficacy and safety of the novel device. This randomised, multicentre, single-blinded, non-inferiority trial compared the BuMA Supreme SES versus a contemporary durable polymer zotarolimus-eluting stent (ZES) in terms of angiographic in-stent late lumen loss (LLL) at nine-month follow-up as the primary endpoint. A total of 170 patients were randomly allocated to treatment with either SES (n=83) or ZES (n=87). At nine-month angiographic follow-up, in-stent LLL was 0.29±0.33 mm in the SES group and 0.14±0.37 mm in the ZES group (pnon-inferiority=0.45). The in-stent percent diameter stenosis and the binary restenosis rate of the two treatment arms were similar (19.2±12.0% vs. 16.1±12.6%, p=0.09, and 3.3% vs. 4.4%, p=1.00, respectively). At 12-month clinical follow-up, there was no difference between treatment arms with regard to the device-oriented composite clinical endpoint (4.9% vs. 5.7%; p=0.72). The PIONEER trial did not meet its primary endpoint in terms of in-stent LLL at nine-month follow-up. However, this result did not translate into any increase in restenosis rate or impairment in 12-month clinical outcomes.

    The reactions between M2(O2CtBu)4, where M=Mo or W, and thienyl-3,4-dicarboxylic acid (0.5-1.5 equiv) in toluene proceed via a series of detectable intermediates to the compounds M8(O2CtBu)4(mu-SC4H2-3,4-{CO2}2)6, which are isolated as air-sensitive yellow (M=Mo) or red (M=W) powders and show parent molecular ions in their mass spectra (MALDI). The structure of the molybdenum complex was determined by single-crystal X-ray crystallography and shown to contain an unusual M8 polygon involving four Mo2 quadruply bonded units linked via the agency of the six 3,4-thienylcarboxylate groups. The structure has crystallographically imposed S4 symmetry and may be described in terms of a highly distorted tetrahedron of Mo2 units or a bisphenoid in which two Mo2 units are linked by a thienyldicarboxylate such that intramolecular Mo2...O bonding is present, while the other thienylcarboxylate bridges merely serve to link these two [Mo2]...[Mo2] units together. The color of the compounds arises from intense M2 delta-to-thienyl pi transitions and, in THF, the complexes are redox-active and show four successive quasi-reversible oxidation waves. The [M8]+ radical cations, generated by one-electron oxidation with AgPF6, are shown to be valence-trapped (class II) by UV-vis-near-IR and electron paramagnetic resonance spectroscopy. These results are supported by the electronic structure calculations on model compounds M8(O2CH)4(mu-SC4H2-3,4-{CO}2)6 employing density functional theory that reveal only a small splitting of the M2 delta manifold via mixing with the 3,4-thienylcarboxylate pi system.

    Full Text Available Discussions about Islamist violence can often be divided into two different trends: one that claims Islam to be essentialy violent per se and another one arguing that violence has nothing to do with Islam. Latter line of argument, particularly in academic discourses, frequently suggests that assailants use religion merely as an instrument to achieve their actually economic-rational interests. However, such argumentation tends to neglect an essential dimension of the whole phenomenon of religiously motivated violence: the spiritual or transcendental worldview which perpetrators use to legitimate their own violence. This article looks into the connection between a religiously based ideology and the representation of violence. To do so, six different documents will be analyzed: the “spiritual guidance“ of the perpetrators involved in the 9/11 attacks (Seidensticker, 2004, four contemporary texts of jihadist actors (mainly from jihadist internet platforms; Lohlker, 2009 and the charter of the terror organization Hamas. Based on these texts, it will be shown how the authors legitimize violence in regard to four fundamental metaphysical principles: the existence of god, the belief in an afterlife, the dichotomous separation of humanity into good and evil and the relevance of a spiritual mindset. The results of the analysis suggest that there is an interior logic of religiously motivated violence, based on premises differentiated from the liberal secularization paradigm and instead following a transcendent understanding of reality. Recognizing this paradigm as one important dimension of Islamist violence could help to better understand such phenomenon and to improve practical work in the field of deradicalization.

    The reaction of [MoO(2)Cl(2)(di-tBu-bipy)] (1) (di-tBu-bipy = 4,4'-di-tert-butyl-2,2'-bipyridine) with water at 100-120 °C in a Teflon-lined stainless steel autoclave, in an open reflux system, or in a microwave synthesis system gave the octanuclear complex [Mo(8)O(22)(OH)(4)(di-tBu-bipy)(4)] (2) as a microcrystalline powder in good yields. Single crystals of 2 suitable for X-ray diffraction were obtained by the reaction of MoO(3) and di-tBu-bipy in water at 160 °C for 3 days. The molecular structure of 2 comprises a purely inorganic core, Mo(4)O(8)(μ(3)-OH)(2)(μ(2)-O)(2), attached to two peripheral oxo-bridged binuclear units, Mo(2)O(4)(μ(2)-O)(2)(OH)(di-tBu-bipy)(2). The inorganic core is composed of a unique assembly of four {MoO(5)} distorted square pyramids connected to each other via edge-sharing. Overall, the octanuclear complex adopts a highly distorted form strongly resembling an "S"-shaped molecular unit. Complex 2 was applied in the catalytic epoxidation of the biorenewable olefins DL-limonene (Lim) and methyl oleate (Ole), using tert-butylhydroperoxide (TBHP) as an oxygen donor, under mild reaction conditions (55 °C, air). The reactions of Lim and Ole gave the respective epoxide monomers in fairly high selectivities at high conversions (89% 1,2-epoxy-p-menth-8-ene selectivity at 96% Lim conversion; 99% methyl 9,10-epoxystearate selectivity at 94% Ole conversion, reached within 24 h reaction).

The connected load totals 830,000 kJ/s, which over the last 10 years has been expanded by an average of 5.3% annually and is currently 2.2% above the national average. The extension of district heat supply has been accomplished without subsidies from the two ZIP programmes. The major objects in Cologne city are to a large extent linked to the GEW district heating network. The goal now is to win more smaller objects in the supply area. To achieve notable new connected load increases in the future, the GEW is conducting a sales promotion drive together with Cologne heating construction firms. The promotion is running under the slogan 'Magically Simple: Heating with District Heat'. Its strategy and execution are described here by the author.

  1. Promoting renewable energy technologies

    Grenaa Jensen, S.

    2004-06-01

    Technologies using renewable energy sources are receiving increasing interest from both public authorities and power producing companies, mainly because of the environmental advantages they procure in comparison with conventional energy sources. These technologies can be substitution for conventional energy sources and limit damage to the environment. Furthermore, several of the renewable energy technologies satisfy an increasing political goal of self-sufficiency within energy production. The subject of this thesis is promotion of renewable technologies. The primary goal is to increase understanding on how technological development takes place, and establish a theoretical framework that can assist in the construction of policy strategies including instruments for promotion of renewable energy technologies. Technological development is analysed by through quantitative and qualitative methods. (BA)

    2018-01-01

     Japan Agency for Medical Research and Development (AMED) was launched in April 2015 to promote integrated medical research and development (R&D) ranging from basic research to practical applications, in order to smoothly achieve the nationwide application of research outcomes, and to establish an environment therefor. AMED consolidates budgets for R&D expenses, which had previously been allocated from different sources, such as the Ministry of Education, Culture, Sports, Science and Technology, the Ministry of Health, Labour and Welfare, and the Ministry of Economy, Trade and Industry. It provides funds strategically to universities, research institutions, etc. By promoting medical R&D, AMED aims to achieve the world's highest level of medical care/services to contribute to a society in which people live long and healthy lives. To achieve this mission, it is imperative that R&D funded by AMED is widely understood and supported. Maintaining and improving research integrity is a prerequisite to this end. AMED is taking various measures to ensure fair and appropriate R&D. It is asking researchers to participate in its responsible conduct in research (RCR) education program and to comply with its rules for managing conflicts of interest (COI). In addition, AMED also conducts a grant program to create and distribute a variety of educational materials on RCR and other matters. Further, AMED is establishing a platform that allows researchers to exchange information about research integrity, and it is undertaking additional measures, such as holding meetings and international symposia on research integrity.

  14. The promotion of happiness.

    Science.gov (United States)

    Klamut, Marian Kazimierz

    2002-01-01

    The human mind is capable of creating an internal world--the psychic sphere--including the phenomena characteristic of human nature, such as selfconsciousness, conscious experiences, conceptual thinking, symbolic language, dreams, art, creation of culture, sense of values, interest in the distant past and care about the distant future. According to the exceptionally concordant opinions of the sages and scholars of the East and the West it is just within this internal world that human happiness dwells. Happiness is a state of the spirit which consists in: internal peace, satisfaction with one's life, the joy of life, benevolence and cordiality towards oneself and towards others; sensitivity to the beauty of nature, culture and art; harmonious co-existence with the surroundings. The achievement and experiencing of the states of thus understood happiness depend mainly on ourselves and, similarly to the project of health promotion, require knowledge, willingness and possibilities. Happiness Promotion denotes the commendation and popularizing of a certain definite way of thinking and acting--showing the road which leads to the frequent experiencing of happy moments.

    2014-12-01

    Full Text Available The link between serotonin (5-HT and one of the most important elements of prosocial behavior, charity, has remained largely uninvestigated. In the present study, we tested whether charitable donating can be promoted by administering the food supplement L-Tryptophan (TRP, the biochemical precursor of 5-HT. Participants were compared with respect to the amount of money they donated when given the opportunity to make a charitable donation. As expected, compared to a neutral placebo, TRP appears to increase the participants’ willingness to donate money to a charity. This result supports the idea that the food we eat may act as a cognitive enhancer modulating the way we think and perceive the world and others.

  3. Anger Promotes Economic Conservatism.

    Kettle, Keri L; Salerno, Anthony

    2017-10-01

    Research suggests that certain facets of people's political ideals can be motivated by different goals. Although it is widely accepted that emotions motivate goal-directed behavior, less is known about how emotion-specific goals may influence different facets of ideology. In this research, we examine how anger affects political ideology and through what mechanisms such effects occur. Drawing on the dual-process motivational model of ideology and the functionalist perspective of emotion, we propose that anger leads people to support conservative economic ideals, which promote economic independence and discourage societal resource sharing. Four studies support our hypothesis that anger can enhance support for an election candidate espousing conservative economic ideals. We find that anger shifts people toward economic conservatism by orienting them toward competition for resources. Implications and future research on the relationship between emotions and political ideology are discussed.

    2017-08-08

    Around the world, increases in wealth have produced an unintended consequence: a rising sense of time scarcity. We provide evidence that using money to buy time can provide a buffer against this time famine, thereby promoting happiness. Using large, diverse samples from the United States, Canada, Denmark, and The Netherlands ( n = 6,271), we show that individuals who spend money on time-saving services report greater life satisfaction. A field experiment provides causal evidence that working adults report greater happiness after spending money on a time-saving purchase than on a material purchase. Together, these results suggest that using money to buy time can protect people from the detrimental effects of time pressure on life satisfaction.

  5. Ambient oxygen promotes tumorigenesis.

    2011-05-01

    Full Text Available Oxygen serves as an essential factor for oxidative stress, and it has been shown to be a mutagen in bacteria. While it is well established that ambient oxygen can also cause genomic instability in cultured mammalian cells, its effect on de novo tumorigenesis at the organismal level is unclear. Herein, by decreasing ambient oxygen exposure, we report a ∼50% increase in the median tumor-free survival time of p53-/- mice. In the thymus, reducing oxygen exposure decreased the levels of oxidative DNA damage and RAG recombinase, both of which are known to promote lymphomagenesis in p53-/- mice. Oxygen is further shown to be associated with genomic instability in two additional cancer models involving the APC tumor suppressor gene and chemical carcinogenesis. Together, these observations represent the first report directly testing the effect of ambient oxygen on de novo tumorigenesis and provide important physiologic evidence demonstrating its critical role in increasing genomic instability in vivo.

  6. Promoting household energy conservation

    International Nuclear Information System (INIS)

    Steg, Linda

    2008-01-01

    It is commonly assumed that households must change their behaviour to reduce the problems caused by increasing levels of fossil energy use. Strategies for behaviour change will be more effective if they target the most important causes of the behaviour in question. Therefore, this paper first discusses the factors influencing household energy use. Three barriers to fossil fuel energy conservation are discussed: insufficient knowledge of effective ways to reduce household energy use, the low priority and high costs of energy savings, and the lack of feasible alternatives. Next, the paper elaborates on the effectiveness and acceptability of strategies aimed to promote household energy savings. Informational strategies aimed at changing individuals' knowledge, perceptions, cognitions, motivations and norms, as well as structural strategies aimed at changing the context in which decisions are made, are discussed. This paper focuses on the psychological literature on household energy conservation, which mostly examined the effects of informational strategies. Finally, this paper lists important topics for future research

    Full Text Available The reactions of 2-acetylpyridine-N(4-phenylthiosemicarbazone, HAP4P, and 2-hydroxyacetophenone-N(4-phenylthiosemicarbazone, H2DAP4P, with R4-mSnXm (m = 2, 3; R = Me, nBu, Ph and X = Cl, Br led to the formation of hexa- and penta-coordinated organotin(IV complexes, which were studied by microanalysis, IR, ¹H-NMR and Mössbauer spectroscopies. The molecular structures of [SnMe2(DAP4P] and [Sn nBu2(DAP4P] were determined by single-crystal X-ray diffraction studies. In the compounds [SnClMe2(AP4P] and [SnBrMe2(AP4P], the deprotonated ligand AP4P- is N,N,S-bonded to the Sn(IV atoms, which exhibit strongly distorted octahedral coordination. The structures of [SnMe2(DAP4P] and [Sn nBu2(DAP4P] revealed that the DAP4P2- anion acts as a O,N,S-tridentate ligand. In these cases, the Sn(IV atoms adopt a strongly distorted trigonal bipyramidal configuration where the azomethine N and the two C atoms are on the equatorial plane while the O and the S atoms occupy the axial positions.

    Full Text Available Introduction Scientists try to answer on the need of a long life with a full physical capability Nonagenarians, centenarians and their closest family members are characterized by a survival benefit throughout life. Moreover, twin studies of longevity suggest that around 25% of the variation in lifespan in developed countries may be inherited. It is therefore worth to examine the role of inter-relationship between nature vs nurture in longevity increment. Material and methods Articles in the EBSCO database have been analyzed using keywords: longevity, gene, behavior, environment. The available literature was subjectively selected. Then, the newest version of every paper was searched for. Results Restriction of calories as well as intake of desirable nutrients can promote adequate control of metabolic pathways and gene expression. APOE, DRD4, Paraoxonase 1, SIRT 3 and SIRT 5 genes can play an important role in longevity. Conclusions Genetic profile and environmental factors seems to both influence on the longevity. Relationships between genetic profile, behavior pattern, quality of life, years spent free from activity limitations and longevity should be examined, to be able to give a recipe on living a long and happy life.

  15. Sales promotions and food consumption.

    Science.gov (United States)

    Hawkes, Corinna

    2009-06-01

    Sales promotions are widely used to market food to adults, children, and youth. Yet, in contrast to advertising, practically no attention has been paid to their impacts on dietary behaviors, or to how they may be used more effectively to promote healthy eating. This review explores the available literature on the subject. The objective is to identify if and what literature exists, examine the nature of this literature, and analyze what can be learned from it about the effects of sales promotions on food consumption. The review finds that while sales promotions lead to significant sales increases over the short-term, this does not necessarily lead to changes in food-consumption patterns. Nevertheless, there is evidence from econometric modeling studies indicating that sales promotions can influence consumption patterns by influencing the purchasing choices of consumers and encouraging them to eat more. These effects depend on the characteristics of the food product, sales promotion, and consumer. The complexity of the effects means that sales promotions aiming to encourage consumption of nutritious foods need to be carefully designed. These conclusions are based on studies that use mainly sales data as a proxy for dietary intake. The nutrition (and economics) research communities should add to this existing body of research to provide evidence on the impact of sales promotions on dietary intake and related behaviors. This would help support the development of a sales promotion environment conducive to healthy eating.

  16. Biofilms promote altruism.

    Science.gov (United States)

    Kreft, Jan-Ulrich

    2004-08-01

    The origin of altruism is a fundamental problem in evolution, and the maintenance of biodiversity is a fundamental problem in ecology. These two problems combine with the fundamental microbiological question of whether it is always advantageous for a unicellular organism to grow as fast as possible. The common basis for these three themes is a trade-off between growth rate and growth yield, which in turn is based on irreversible thermodynamics. The trade-off creates an evolutionary alternative between two strategies: high growth yield at low growth rate versus high growth rate at low growth yield. High growth yield at low growth rate is a case of an altruistic strategy because it increases the fitness of the group by using resources economically at the cost of decreased fitness, or growth rate, of the individual. The group-beneficial behaviour is advantageous in the long term, whereas the high growth rate strategy is advantageous in the short term. Coexistence of species requires differences between their niches, and niche space is typically divided into four 'axes' (time, space, resources, predators). This neglects survival strategies based on cooperation, which extend the possibilities of coexistence, arguing for the inclusion of cooperation as the fifth 'axis'. Here, individual-based model simulations show that spatial structure, as in, for example, biofilms, is necessary for the origin and maintenance of this 'primitive' altruistic strategy and that the common belief that growth rate but not yield decides the outcome of competition is based on chemostat models and experiments. This evolutionary perspective on life in biofilms can explain long-known biofilm characteristics, such as the structural organization into microcolonies, the often-observed lack of mixing among microcolonies, and the shedding of single cells, as promoting the origin and maintenance of the altruistic strategy. Whereas biofilms enrich altruists, enrichment cultures, microbiology's paradigm

    2014-06-01

    Full Text Available Marketing has proven to be very useful instrument in the wine industry, in fostering comprehensive, cohesive and effective strategies which wineries require to effectively compete in today’s almost saturated wine market. But within wine marketing, the promotion strategy, from our point of view, is the most important component of the winery that can ensure the success in the market or can shorten the life cycle of the product. This being said, the aim of the paper is twofold. Firstly, to determine and analyze the steps that are required to create a promotion strategy in the wine industry, by comparing different approaches. Secondly, to identify the instruments of the promotional mix that helps a winery to implement its promotional strategy. Bearing that in mind, the paper starts with some theoretical aspects regarding the promotion strategy and ends by providing a brief overview of the main findings.

    This article discusses a model that can be used in order to analyse notions on literature promotion in public libraries. The model integrates different issues which interact with how literature promotion is understood and thought of in public libraries. Besides cultural policy we regard the logics...... of new public management (NPM) and professional logics in the field of public libraries. Cultural policy along with the identification of underlying logics present among politicians, government officials, managers and librarians/promoters of literature, play an important part in creating an understanding...... of literature promotion in Danish libraries. Thus the basic premise for the development of the model is that cultural policy (Policy) has an important influence on notions on literature promotion and other activities in public libraries, but that cultural policy must be seen in some kind of interaction...

  1. MCH promotes family planning.

    1992-06-01

    Family planning (FP) has been promoted in China through improvements in maternal and child health (MCH) which have affected people's attitude toward childbearing. A case study of FP in Taicang County of Jiangsu Province, China is given. Total population is 446,620; natural increase is 10/1000. 99% of births have been planned in recent years. Contraceptive prevalence has reached 92.71%. Contraceptive awareness has opened people up to health education in general. The community participates in management of human wastes, improvement of water supplies, and parasite control in rural areas. MCH was begun in the early 1980s with premarital examinations, prenatal examinations, postnatal visits, and physical checkups. A systematic program has established in 1983. A pilot program integrating FP, MCH, and parasite control operated between 1984 and 1986, in 7 townships was established and MCH was institutionalized. Increases occurred in comprehensive care for women from 49.1% in 1984 to 78.3% in 1986. Children's coverage rose from 78.2% to 85.9%. Perinatal mortality dropped from 30.2/1000 to 20.8/1000. Neonatal mortality declined from 21.3/1000 to 17.3/1000. Infant mortality also decreased from 31.6/1000 to 21.5/1000. Integration of programs throughout the county was achieved after 1987. 99% of women used the MCH handbook. Between 1987 and 1990, the perinatal, neonatal, and infant mortality rate dropped to 12.9/1000, 9.5/1000, and 14.7/1000, respectively. MCH achievements are attributed to a strengthening of the MCH network to improve access and improve MCH workers' level of professional skill, to the availability of premarriage and couples of reproductive age services and child care, and to the contribution of research. Careful monitoring during pregnancy helped reduce the incidence of difficult labors for high risk women from 17.55 in 1984 to 11-15% in recent years. 99.9% deliver in hospitals. There were no maternal deaths in 1989 or 1990. Neonatal tetanus has been

    The synthesis, chemical and structural characterization of a series of pentamethylcyclopentadienyl (Cp*) tantalum imido complexes and aryloxide derivatives are presented. Specifically, the imido complexes Cp*Ta(N(t)Bu)(CH(2)R)(2), where R = Ph [dibenzyl(tert-butylamido) (η(5)-pentamethylcyclopentadienyl)tantalum(IV) (1)], Me(2)Ph [tert-butylamido)bis(2-methyl-2-phenylpropyl) (η(5)-pentamethylcyclopentadienyl)tantalum(IV) (2)], CMe(3) [(tert-butylamido)bis(2,2-dimethylpropyl) (η(5)-pentamethylcyclopentadienyl)tantalum(IV) (3)], are reported. The crystal structure of (3) reveals α-agostic interactions with the Ta atom. The resulting increase in the tantalum core coordination improves electronic stability. As such it does not react with pentafluorophenol, in contrast to the other two reported imido complexes [(1) and (2)]. Addition of C(6)F(5)OH to (1) yields a dimeric aryl-oxide derivative, [Cp*Ta(CH(2)Ph)(OC(6)H(5))(μ-O)](2) [di-μ-oxido-bis[benzyl(pentafluorophenolato) (η(5)-pentamethylcyclopentadienyl)tantalum(V)] (4)]. Its crystal structure reveals long Ta-O(C(6)H(5)) bonds but short oxo-bridging Ta-O bonds. This is explained by accounting for the fierce electronic competition for the vacant d(π) orbitals of the electrophilic Ta(V) centre. Steric congestion around each metal is alleviated by a large twist angle (77.1°) between the benzyl and pentafluorophenyl ligands and the ordering of each of these groups into stacked pairs. The imido complex (2) reacts with C(6)F(5)OH to produce a mixture of Cp*Ta(OC(6)F(5))(4) [tetrakis(pentafluorophenolato)(η(5)-pentamethylcyclopentadienyl)tantalum(V) (5)] and [Cp*Ta(OC(6)F(5))(2)(μ-O)](2) [di-μ-oxido-bis[bis(pentafluorophenolato)(η(5)-pentamethylcyclopentadienyl)tantalum(V)] (6)]. Steric congestion is offset in both cases by the twisting of its pentafluorophenyl ligands. Particularly strong electronic competition for the empty d(π) metal orbitals in (6) is reflected in its bond geometry, and owes itself to the

    The complexes [Ni(S2CR)(triphos)]BPh4 (R = Me, Et, Bu(n) or Ph; triphos = PhP{CH2CH2PPh2}2) have been prepared and characterised. X-ray crystallography (for R = Et, Ph, C6H4Me-4, C6H4OMe-4 and C6H4Cl-4) shows that the geometry of the five-coordinate nickel in the cation is best described as distorted trigonal bipyramidal, containing a bidentate carboxydithioate ligand with the two sulfur atoms spanning axial and equatorial sites, the other axial site being occupied by the central phosphorus of triphos. The reactions of [Ni(S2CR)(triphos)](+) with mixtures of HCl and Cl(-) in MeCN to form equilibrium solutions containing [Ni(SH(S)CR)(triphos)](2+) have been studied using stopped-flow spectrophotometry. The kinetics show that proton transfer is slower than the diffusion-controlled limit and involves at least two coupled equilibria. The first step involves the rapid association between [Ni(S2CR)(triphos)](+) and HCl to form the hydrogen-bonded precursor, {[Ni(S2CR)(triphos)](+)HCl} (K) and this is followed by the intramolecular proton transfer (k) to produce [Ni(SH(S)CR)(triphos)](2+). In the reaction of [Ni(S2CMe)(triphos)](+) the rate law is consistent with the carboxydithioate ligand undergoing chelate ring-opening after protonation. It seems likely that chelate ring-opening occurs for all [Ni(S2CR)(triphos)](+), but only with [Ni(S2CMe)(triphos)](+) is the protonation step sufficiently fast that chelate ring-opening is rate-limiting. With all other systems, proton transfer is rate-limiting. DFT calculations indicate that protonation can occur at either sulfur atom, but only protonation at the equatorial sulfur results in chelate ring-opening. The ways in which protonation of either sulfur atom complicates the analyses and interpretation of the kinetics are discussed.

    Full Text Available The objective of this review was to describe the scientific evidence for coordinating health promotion at the workplace and to discuss the required future research in this field. Literature review from March 1990 to November 2014 was performed. Using the keywords ′health, promotion, worksite and workplace′, literature was searched in the following databases: Medline, PubMed and Google Scholar; with no time limit. There is emerging evidence that workplace health promotion enhances the effectiveness of effort to promote and protect workers′ health. It proves both cost-effective and cost-beneficial to health promotion at the worksite and subsequently further reduces absenteeism. However, future research is needed to identify the impact of other factors such as age, gender and race on workers′ exposure. There is also a need to develop valid tests to measure the outcome of these programmes at the workplace. Health promotion should be central to workplace planning and should be recognised as an integral part of proactive occupational health. Indeed, the workplace is viewed as one of the most popular venues for promoting health and preventing diseases among employees.

  7. Information technology in health promotion.

    2008-06-01

    eHealth, the use of information technology to improve or enable health and health care, has recently been high on the health care development agenda. Given the vivid interest in eHealth, little reference has been made to the use of these technologies in the promotion of health. The aim of this present study was to conduct a review on recent uses of information technology in health promotion through looking at research articles published in peer-reviewed journals. Fifteen relevant journals with issues published between 2003 and June 2005 yielded altogether 1352 articles, 56 of which contained content related to the use of information technology in the context of health promotion. As reflected by this rather small proportion, research on the role of information technology is only starting to emerge. Four broad thematic application areas within health promotion were identified: use of information technology as an intervention medium, use of information technology as a research focus, use of information technology as a research instrument and use of information technology for professional development. In line with this rather instrumental focus, the concepts 'ePromotion of Health' or 'Health ePromotion' would come close to describing the role of information technology in health promotion.

    This paper advocates that mental health promotion receive appropriate attention within health promotion. It is of great concern that, in practice, mental health promotion is frequently overlooked in health promotion programmes although the WHO definitions of health and the Ottawa Charter describe mental health as an integral part of health. It is suggested that more attention be given to addressing the determinants of mental health in terms of protective and risk factors for both physical and mental conditions, particularly in developing countries. Examples of evidence-based mental health programmes operating in widely diverse settings are presented to demonstrate that well designed interventions can contribute to the well-being of populations. It is advocated that particular attention be given to the intersectorial cooperation needed for this work.

  9. Health promotion: an ethical analysis.

    Science.gov (United States)

    Carter, Stacy M

    2014-04-01

    Thinking and practising ethically requires reasoning systematically about the right thing to do. Health promotion ethics - a form of applied ethics - includes analysis of health promotion practice and how this can be ethically justified. Existing frameworks can assist in such evaluation. These acknowledge the moral value of delivering benefits. But benefits need to be weighed against burdens, harms or wrongs, and these should be minimised: they include invading privacy, breaking confidentiality, restraining liberty, undermining self-determination or people's own values, or perpetuating injustice. Thinking about the ethics of health promotion also means recognising health promotion as a normative ideal: a vision of the good society. This ideal society values health, sees citizens as active and includes them in decisions that affect them, and makes the state responsible for providing all of its citizens, no matter how advantaged or disadvantaged, with the conditions and resources they need to be healthy. Ethicists writing about health promotion have focused on this relationship between the citizen and the state. Comparing existing frameworks, theories and the expressed values of practitioners themselves, we can see common patterns. All oppose pursuing an instrumental, individualistic, health-at-all-costs vision of health promotion. And all defend the moral significance of just processes: those that engage with citizens in a transparent, inclusive and open way. In recent years, some Australian governments have sought to delegitimise health promotion, defining it as extraneous to the role of the state. Good evidence is not enough to counter this trend, because it is founded in competing visions of a good society. For this reason, the most pressing agenda for health promotion ethics is to engage with communities, in a procedurally just way, about the role and responsibilities of the citizen and the state in promoting and maintaining good health.

    The World Health Organization states that health promotion is a key strategy to improve health, and it is conceived as a global process of enabling people to increase control over, and to improve, their health. Health promotion does not focus solely on empowering individuals dealing with their knowledge, attitudes and skills, but it also takes political, social, economic and environmental aspects influencing health and wellbeing into account. The complexity of applying these concepts is reflected in the five paradoxes in health promotion; these arise in between the rhetoric in health promotion and implementation. The detected paradoxes which are described herein involve the patient versus the person, the individual versus the group, disease professionals versus health professionals, disease indicators versus health indicators, and health as an expense versus health as an investment. Making these contradictions explicit can help determine why it is so complex to put the concepts related to health promotion into practice. It can also help to put forward aspects that need further work if health promotion is to put into practice. Copyright © 2017 SESPAS. Publicado por Elsevier España, S.L.U. All rights reserved.

  1. Drug promotion practices: A review.

    2018-01-18

    Over the years, the pharmaceutical industry has been at the forefront of research and innovation in drug discovery and development. The process of drug discovery extending from preclinical studies to multicentric clinical trials and postmarketing phase is a costly affair running into billions of dollars. On the flip side, not all investigational molecules clear the trial phases and get approved, which puts pressure on the manufacturers to maximize the profit from approved drugs. It is in this key area that the practice of drug promotion plays its role. The World Health Organization defines drug promotion as "all informational and persuasive activities by manufacturers and distributors, the effect of which is to influence the prescription, supply, purchase or use of medicinal drugs". With its humble intent of creating awareness among healthcare professionals and updating their knowledge on recent advances in treatment options, drug promotion has been an important tool, but gradually it has evolved to embrace aggressive marketing strategies and sometimes unethical business and scientific practices where the need for profit-making eclipses commitment to patient care and scientific exploration. In this review, we discuss the evolution of drug promotion practices, the various types, its merits and demerits, the influence of drug promotion on physician prescribing behaviour, the role of regulatory bodies, unethical promotional practices and finally summarize with future directions. © 2018 The British Pharmacological Society.

    The superbulky deca-aryleuropocene [Eu(Cp(BIG))2], Cp(BIG) = (4-nBu-C6H4)5-cyclopentadienyl, was prepared by reaction of [Eu(dmat)2(thf)2], DMAT = 2-Me2N-α-Me3Si-benzyl, with two equivalents of Cp(BIG)H. Recrystallizyation from cold hexane gave the product with a surprisingly bright and efficient orange emission (45% quantum yield). The crystal structure is isomorphic to those of [M(Cp(BIG))2] (M = Sm, Yb, Ca, Ba) and shows the typical distortions that arise from Cp(BIG)⋅⋅⋅Cp(BIG) attraction as well as excessively large displacement parameter for the heavy Eu atom (U(eq) = 0.075). In order to gain information on the true oxidation state of the central metal in superbulky metallocenes [M(Cp(BIG))2] (M = Sm, Eu, Yb), several physical analyses have been applied. Temperature-dependent magnetic susceptibility data of [Yb(Cp(BIG))2] show diamagnetism, indicating stable divalent ytterbium. Temperature-dependent (151)Eu Mössbauer effect spectroscopic examination of [Eu(Cp(BIG))2] was examined over the temperature range 93-215 K and the hyperfine and dynamical properties of the Eu(II) species are discussed in detail. The mean square amplitude of vibration of the Eu atom as a function of temperature was determined and compared to the value extracted from the single-crystal X-ray data at 203 K. The large difference in these two values was ascribed to the presence of static disorder and/or the presence of low-frequency torsional and librational modes in [Eu(Cp(BIG))2]. X-ray absorbance near edge spectroscopy (XANES) showed that all three [Ln(Cp(BIG))2] (Ln = Sm, Eu, Yb) compounds are divalent. The XANES white-line spectra are at 8.3, 7.3, and 7.8 eV, for Sm, Eu, and Yb, respectively, lower than the Ln2O3 standards. No XANES temperature dependence was found from room temperature to 100 K. XANES also showed that the [Ln(Cp(BIG))2] complexes had less trivalent impurity than a [EuI2(thf)x] standard. The complex [Eu(Cp(BIG))2] shows already at room temperature

    2017-03-01

    The arrival of a new summer collegiate baseball league franchise to a small central New York city was seen as an opportunity for health promotion. The initiative was set up to explore two overarching questions: (1) Are summer collegiate baseball events acceptable to local public health organizations as viable places for health promotion activities addressing local health issues? (2) Are summer collegiate baseball organizations amenable to health promotion activities built in to their fan and/or player experiences? Planning and implementation were guided by precede-proceed, social cognitive theory, social marketing, and diffusion of innovations constructs. Environmental changes were implemented to support healthy eating and nontobacco use by players and fans; four health awareness nights were implemented at home games corresponding to local public health priorities and included public service announcements, between inning quizzes, information dissemination at concession and team market locations, and special guests. Sales and fan feedback support mostly healthy concession offerings and a tobacco-free ballpark; postseason evaluations from team staff and public health partners support continuing the trials of this sports event as a venue for health promotion.

The territorial understanding of "Belarusness", in conjunction with the nearly atavistic antibolshevism of Bałachowicz, were a great asset in Józef Piłsudski's new political combination. Piłsudski decided to benefit from Savinkov's idealistic approach for his own purpose.

  19. Competitive intransitivity promotes species coexistence.

    Science.gov (United States)

    Laird, Robert A; Schamp, Brandon S

    2006-08-01

    Using a spatially explicit cellular automaton model with local competition, we investigate the potential for varied levels of competitive intransitivity (i.e., nonhierarchical competition) to promote species coexistence. As predicted, on average, increased levels of intransitivity result in more sustained coexistence within simulated communities, although the outcome of competition also becomes increasingly unpredictable. Interestingly, even a moderate degree of intransitivity within a community can promote coexistence, in terms of both the length of time until the first competitive exclusion and the number of species remaining in the community after 500 simulated generations. These results suggest that modest levels of intransitivity in nature, such as those that are thought to be characteristic of plant communities, can contribute to coexistence and, therefore, community-scale biodiversity. We explore a potential connection between competitive intransitivity and neutral theory, whereby competitive intransitivity may represent an important mechanism for "ecological equivalence."

  1. South Asia's health promotion kaleidoscope.

    Mukhopadhyay, Alok

    2007-01-01

    South Asia has 22 percent of the world's population but only 1.3 percent of the global income. Consequently 40 percent of the population is living in absolute poverty. However the health transition in some of its countries including India and Sri Lanka is a testimony to the fact that there are proven solutions to the problems of health and development within the region. The countries of the region have much in common, including a democratic political system, four major religions, a vibrant and living tradition of voluntarism and an extensive health infrastructure which is operating well below par. Despite the underlying unity, South Asia enjoys enormous cultural, linguistic and ethnic diversity. In this large, complex and vibrant region, health promotion is a challenging task, but it also holds the key to a dramatic change in the global health situation. Many of these solutions lie in wider areas of socio-political action. There are much needed shifts in the health promotion and development efforts, particularly in the area of poverty and social justice; gender inequity; population stabilisation; health and environment; control of communicable and non-communicable diseases; and urban health strategies. The principle of cooperation, partnership and intersectoral collaboration for health will be explored. Developing an appropriate, sustainable and people centred health and development strategy in the coming decades is an enormous challenge. There has been an attempt to focus on the emerging needs of the region, which call for health promotion, and involvement of civil society, private sector and the governments bestowed with the increased responsibility of ensuring health security for people. Strengthening the existing health systems, allocating adequate resources for health development and ensuring community participation are all prerequisites to the success of health promotion in the region.

Statistical population of the study includes Sport Goods-Producing companies in Iran (N= 180 and 122 firms formed the study sample. For testing the hypothesis, we have used Paired Samples T-Test. The analysis of findings showed that there was a meaningful difference between using advertising and sales promotion strategies. In general, we can say, there are some limited applications of using techniques and methods of sales promotion strategies in Iranian sport industry and methods of advertising. Consequently, regarding the intense competition among companies as well as fast growth of markets and fast changes in consumer’s behavior, identifying the best methods for corresponding relationship to customer would be required.

    Over the past 60 years, population control has become an increasingly urgent issue worldwide as a growing population strains already limited resources. The use of financial incentives to promote family planning is an innovative approach that has potential to make a contribution to efforts to better manage population growth. This report reviews eight studies that examined the effect of incentives on family planning. Published studies that tested the impact of incentives to promote some aspect of family planning and included an appropriate control or comparison condition were reviewed. Incentives have been used to promote attendance at contraceptive education sessions, adoption and continuation of contraceptive methods, sterilization, and to limit family size. All but one of the eight studies reviewed reported positive outcomes, but weaknesses in study design and execution limit the strength of the conclusions that can be drawn. Review of this literature suggests that family planning behaviors, like other behaviors, are sensitive to incentives. Given the tremendous need for efficacious interventions in global efforts to manage population growth, further research on this topic using more rigorous experimental methods is warranted.

  5. Engineered Promoters for Potent Transient Overexpression.

    Directory of Open Access Journals (Sweden)

    Dan Y Even

    Full Text Available The core promoter, which is generally defined as the region to which RNA Polymerase II is recruited to initiate transcription, plays a pivotal role in the regulation of gene expression. The core promoter consists of different combinations of several short DNA sequences, termed core promoter elements or motifs, which confer specific functional properties to each promoter. Earlier studies that examined the ability to modulate gene expression levels via the core promoter, led to the design of strong synthetic core promoters, which combine different core elements into a single core promoter. Here, we designed a new core promoter, termed super core promoter 3 (SCP3, which combines four core promoter elements (the TATA box, Inr, MTE and DPE into a single promoter that drives prolonged and potent gene expression. We analyzed the effect of core promoter architecture on the temporal dynamics of reporter gene expression by engineering EGFP expression vectors that are driven by distinct core promoters. We used live cell imaging and flow cytometric analyses in different human cell lines to demonstrate that SCPs, particularly the novel SCP3, drive unusually strong long-term EGFP expression. Importantly, this is the first demonstration of long-term expression in transiently transfected mammalian cells, indicating that engineered core promoters can provide a novel non-viral strategy for biotechnological as well as gene-therapy-related applications that require potent expression for extended time periods.

    Electrochemical reduction of CO 2 is a promising method to convert CO 2 into fuels or useful chemicals, such as carbon monoxide (CO), hydrocarbons, and alcohols. In this study, nanostructured Ag was obtained by electrodeposition of Ag in the presence of a Keggin type polyoxometalate, [PMo 12 O 40 ] 3- (PMo). Metallic Ag is formed upon reduction of Ag + . Adsorption of PMo on the surface of the newly formed Ag lowers its surface energy thus stabilizes the nanostructure. The electrocatalytic performance of this Ag-PMo nanocomposite for CO 2 reduction was evaluated in a CO 2 saturated dimethylformamide medium containing 0.1 M [ n-Bu 4 N]PF 6 and 0.5% (v/v) added H 2 O. The results show that this Ag-PMo nanocomposite can catalyze the reduction of CO 2 to CO with an onset potential of -1.70 V versus Fc 0/+ , which is only 0.29 V more negative than the estimated reversible potential (-1.41 V) for this process and 0.70 V more positive than that on bulk Ag metal. High faradaic efficiencies of about 90% were obtained over a wide range of applied potentials. A Tafel slope of 60 mV dec -1 suggests that rapid formation of *CO 2 •- is followed by the rate-determining protonation step. This is consistent with the voltammetric data which suggest that the reduced PMo interacts strongly with CO 2 (and presumably CO 2 •- ) and hence promotes the formation of CO 2 •- .

    The hypothesis that evolvability - the capacity to evolve by natural selection - is itself the object of natural selection is highly intriguing but remains controversial due in large part to a paucity of direct experimental evidence. The antigenic variation mechanisms of microbial pathogens provide an experimentally tractable system to test whether natural selection has favored mechanisms that increase evolvability. Many antigenic variation systems consist of paralogous unexpressed 'cassettes' that recombine into an expression site to rapidly alter the expressed protein. Importantly, the magnitude of antigenic change is a function of the genetic diversity among the unexpressed cassettes. Thus, evidence that selection favors among-cassette diversity is direct evidence that natural selection promotes antigenic evolvability. We used the Lyme disease bacterium, Borrelia burgdorferi, as a model to test the prediction that natural selection favors amino acid diversity among unexpressed vls cassettes and thereby promotes evolvability in a primary surface antigen, VlsE. The hypothesis that diversity among vls cassettes is favored by natural selection was supported in each B. burgdorferi strain analyzed using both classical (dN/dS ratios) and Bayesian population genetic analyses of genetic sequence data. This hypothesis was also supported by the conservation of highly mutable tandem-repeat structures across B. burgdorferi strains despite a near complete absence of sequence conservation. Diversification among vls cassettes due to natural selection and mutable repeat structures promotes long-term antigenic evolvability of VlsE. These findings provide a direct demonstration that molecular mechanisms that enhance evolvability of surface antigens are an evolutionary adaptation. The molecular evolutionary processes identified here can serve as a model for the evolution of antigenic evolvability in many pathogens which utilize similar strategies to establish chronic infections.

    The radioisotope {sup 89}Sr as {sup 89}SrCl{sub 2} is medically useful for bone pain palliation and is produced in fast reactors using the {sup 89}Y(n, p){sup 89}Sr reaction. A procedure for isolation of the radionuclide {sup 89}Sr by chemical processing of the irradiated Y{sub 2}O{sub 3} target has been standardised and trial runs have been carried out at the Fast Breeder Test Reactor (FBTR), Kalpakkam. The chemical processing of the irradiated Y{sub 2}O{sub 3} target involves (i) the removal of target Y(III) by TBP extraction and (ii) further purification of the separated {sup 89}Sr fraction by cationic exchange chromatography. However a selective isolation of {sup 89}Sr by the Sr-specific crown ether makes the above chemical processing faster and relatively simple. This work presents a study on the selective removal of Sr from the irradiated target dissolver solution using the Sr-specific crown ether 4,4{sup '}(5{sup '}) di-tert-butyl-cyclohexano-18-crown-6 (DtBuCH18C6) in octanol medium. The separation behaviour of the other impurities such as Ce(IV), Y(III), Tb(III), Eu(III), Zn(II), Mn(II) and Rb(I) present along with Sr(II) in the irradiated sample was also investigated. The method of separation by using the crown ether DtBuCH18C6 is proved to be a potential tool for the purification of {sup 89}Sr(II) source produced from yttria target in fast reactors.

  11. PROMOTION OF MONTENEGRO THROUGH SPORTS

    Directory of Open Access Journals (Sweden)

    Dervis Selhanovic

    2011-03-01

    Full Text Available Modern social structures of Montenegro exist in a hypercomplex and very dynamic environment. The complexity and dynamism are, in part, a consequence of the general characteristics of the modern age, and in part, of the transition processes which have affected the Montenegrin society. The transition processes are taking place at all levels and subsystems of the community, and its sociological milieu is facing inevitability of adaptation and immersion in such processes and trends. There is no more positive promotion for a country than a sports promotion. There is no expert team, public relations agency or a lawyer than can win Montenegro a front page. We can talk about the importance of sports for the promotion of Montenegro from another point of view. If we compare the number of occurrences of names of the selected Montenegrin athletes with that of politicians, scientists or artists in different internet search engines, we will realize how great is the capacity of marketing potential that lies in Montenegrin sports and top athletes as representatives of the products and services with the label - Made in Montenegro. In addition to the success of the Montenegrin athletes globally, the promotion of Montenegro through sports is directly contributed by the major sporting events and contests, on account of which Montenegro presented itself not only as an excellent host and organizer, but also demonstrated the remarkable state and marketing capabilities and competencies. Reputation (image is not achieved overnight. Its semiological and symbolic charge includes all (visual, vocal, environmental, personal, active inputs, which need to be channelled and created. Indeed, continual work in creating and maintaining the image of Montenegro is a public relations function. With efficiently and professionally developed media and PR strategy, the modern state of Montenegro may expect to favourably position its image at the international scene, and to present its

    2014-01-01

    In the recent surge of metal-free polymerization techniques, phosphazene bases have shown their remarkable potential as organic promoters/catalysts for the anionic polymerization of various types of monomers. By complexation with the counterion (e.g. proton or lithium cation), phosphazene base significantly improve the nucleophilicity of the initiator/chain-end resulting in rapid and usually controlled anionic/quasi-anionic polymerization. In this review, we will introduce the general mechanism, i.e. in situ activation (of initiating sites) and polymerization, and summarize the applications of such a mechanism on macromolecular engineering toward functionalized polymers, block copolymers and complex macromolecular architectures.

    Okazaki, Shintaro; Rubio, Natalia; Campo, Sara

    2013-02-01

    Online gossip has been recognized as small talk on social networking sites (SNSs) that influences consumer behavior, but little attention has been paid to its role. This study makes three theoretical predictions: (a) propensity to gossip online leads to greater information value, entertainment value, and friendship value; (b) upon exposure to a high-involvement product, online gossipers are more willing to spread such information through electronic word-of-mouth (eWOM) in search of prestige or fame as a knowledge expert; and (c) this tendency will be more pronounced when they are connected with strong ties (rather than weak ties) and belong to a large network (rather than a small network). An experimental survey was conducted with a scenario method. In total, 818 general consumers participated in the survey. A multivariate analysis of variance (ANOVA) provides empirical support for prediction (1). With regard to predictions (2) and (3), a series of three-way and two-way between-subjective ANOVAs were performed. When a high-involvement product is promoted, gossipers, rather than nongossipers, are more willing to participate in eWOM on an SNS. Furthermore, a significant interaction effect indicates that online gossipers' willingness to particiapte in eWOM would be more pronounced if they belonged to a large network rather than a small network. However, when a low-involvement product is promoted, no interaction effect is found between online gossip and network size. In closing, theoretical and managerial implications are discussed, while important limitations are recognized.

  3. International energy-promotion-activities

    Comprehensive promotion of energy and environmental measures are demanded in order to realize improvement in energy demand/supply structures in developing countries where increase in energy demand is anticipated. To achieve this goal, technical transfer related to energy saving technologies and clean coal as well as international energy promotion activities are implemented in China and Indonesia since fiscal 1993. In the field of energy saving, model operations are performed to improve efficiency in such energy consuming fields as steel making, power generation, and oil refining, in addition to cooperation in structuring databases and establishing master plans. In the clean coal field, model operations are conducted to reduce environmental load in coal utilizing areas, in addition to cooperation in establishing master plans for coal utilization. This paper describes feasibility studies on environmentally harmonious coal utilization systems in developing countries, assistance to introduction thereof, and joint verification operations. To rationalize international energy usage, basic surveys on energy utilization efficiency improvement and model operations are carried out mainly in the Asia-Pacific countries.

    1977-01-01

    A survey was conducted on the promotion of 28 prescription drugs in the form of 40 different products marketed in the United States and Latin America by 23 multinational pharmaceutical companies. Striking differences were found in the manner in which the identical drug, marketed by the identical company or its foreign affiliate, was described to physicians in the United States and to physicians in Latin America. In the United States, the listed indications were usually few in number, while the contraindications, warnings, and potential adverse reactions were given in extensive detail. In Latin America, the listed indications were far more numerous, while the hazards were usually minimized, glossed over, or totally ignored. The differences were not simply between the United States on the one hand and all the Latin American countries on the other. There were substantial differences within Latin America, with the same global company telling one story in Mexico, another in Central America, a third in Ecuador and Colombia, and yet another in Brazil. The companies have sought to defend these practices by contending that they are not breaking any Latin American laws. In some countries, however, such promotion is in clear violation of the law. The corporate ethics and social responsibilities concerned here call for examination and action.

    2000-03-01

    To establish whether there is a role for advertising in the promotion of the Breast Screening Programme and what the role of advertising might be. Four hundred and sixty questionnaires were completed by women attending their breast screening appointment. Quantitative and qualitative data were collected from the static unit at Calder Street and the mobile unit in Govan. The advertising (budget 30,000 Pounds) campaign ran over an eight week period in the Govan, Paisley Road West and Cardonald areas of Glasgow. Media used included press advertising, The Glasgow Underground, adshells, bus advertising (interiors) and poster distribution via local outlets. Forty-two per cent of the sample were aware of the campaign. Ninety-seven per cent liked the campaign images. Eighty eight per cent felt that breast screening should be advertised more. Screening uptake increased in the areas covered by the advertising campaign. Govan -58%-71% and Ibrox (Paisley Road West and Cardonald) -59%-61%. Women were very supportive of the role of advertising for the Breast Screening Programme. In particular they found the campaign images and messages reassuring, supportive and credible. Their views suggest that the role of advertising should be: To raise awareness of the service To make women more conscious of the benefits of screening To change public perceptions of the screening process However, it is recognised that a fully integrated approach is required for the promotion of the service to account for the improvement in uptake, as advertising cannot be expected to work in isolation.

    2013-06-01

    The Global Working Group on Health Promotion Research (GWG HPR) of the International Union for Health Promotion and Education (IUHPE) presents a collection of four articles illustrating innovative avenues for health promotion research. This commentary synthesizes the contributions of these articles while attempting to define the contours of research in health promotion. We propose that innovation in research involves the adoption of a reflexive approach wherein consideration of context plays different roles. The reflexive process consists of questioning what is taken for granted in the conceptualization and operationalization of research. It involves linking research findings and its theoretical foundations to characteristics and goals of the field and observed realities, while orienting reflection on specific objects. The reflexive nature of the research activity is of paramount importance for innovation in health promotion. With the publication of this series, the GWG HPR wishes to strengthen health promotion research capacity at the global level and reaffirm health promotion as a specific research domain.

    Chaenomeles is a genus of deciduous spiny in the family of Rosaceae (Pomoideae subfamily). For centuries, the plant was used for a treatment of anemia, rheumatism, gout and cardiovascular diseases. The chemical composition studies of Chaenomeles showed the presence of many biologically active compounds, such as: phenolic compounds, organic acids, terpenoids, alcohols, ketones or aldehydes. Fruit of Chaenomeles has the largest applying potential due to extensive use of medicinal and high concentration of vitamin C. Recent in vivo and in vitro studies suggest that Chaenomeles fruit can help in the healing process of diabetes, tumor, allergies and liver diseases. Futhermore the plant has many positive qualities, like: hepatoprotective effect, anti-inflammatory properties, antioxidant action, antimicrobial and neuroprotective effect. Chaenomeles fruit may promote the growth of beneficial intestinal microflora and contribute to the regulation of body weight. The aim of this review was to summarize the information and data on the chemical composition and therapeutic properties of Chaenomeles.

    2005-06-15

    Green chemistry is an important tool in achieving sustainability. The implementation of green chemistry, the design of chemical products and processes that reduce or eliminate the use and generation of hazardous substances, is essential if the expanding global population is to enjoy an increased standard of living without having a negative impact on the health of the planet. Cleaner technologies will allow the chemical enterprise to provide society with the goods and services on which it depends in an environmentally responsible manner. Green chemistry provides solutions to such global challenges as climate change, sustainable agriculture, energy, toxics in the environment, and the depletion of natural resources. A collaborative effort by industry, academia, and government is needed to promote the adoption of the green chemistry technologies necessary to achieve a sustainable society.

    Stress granules (SGs) harbour translationally stalled messenger ribonucleoproteins and play important roles in regulating gene expression and cell fate. Here we show that neddylation promotes SG assembly in response to arsenite-induced oxidative stress. Inhibition or depletion of key components of the neddylation machinery concomitantly inhibits stress-induced polysome disassembly and SG assembly. Affinity purification and subsequent mass-spectrometric analysis of Nedd8-conjugated proteins from translationally stalled ribosomal fractions identified ribosomal proteins, translation factors and RNA-binding proteins (RBPs), including SRSF3, a previously known SG regulator. We show that SRSF3 is selectively neddylated at Lys85 in response to arsenite. A non-neddylatable SRSF3 (K85R) mutant do not prevent arsenite-induced polysome disassembly, but fails to support the SG assembly, suggesting that the neddylation pathway plays an important role in SG assembly.

    Freed, Patricia; SmithBattle, Lee

    2016-01-01

    In this second article in a two-part series, we call for the integration of strengths-based and trauma-informed care into services for teen mothers. Nurses working with teen mothers in health clinics, schools and home visiting programs can play a pivotal role in promoting their mental health. Many teen mothers have high levels of psychological distress and histories of adverse experiences that cannot be ignored, and cannot solely be addressed by referral to mental health services. Nurses must be prepared to assess for trauma and be open to listening to teen mothers' experiences. Principles of strengths-based and trauma-informed care are complementary and can be integrated in clinical services so that teen mothers' distress is addressed and their strengths and aspirations are supported. Potential screening tools, interviewing skills and basic strategies to alleviate teen mothers' distress are discussed.

    2013-01-01

    Abstract Online gossip has been recognized as small talk on social networking sites (SNSs) that influences consumer behavior, but little attention has been paid to its role. This study makes three theoretical predictions: (a) propensity to gossip online leads to greater information value, entertainment value, and friendship value; (b) upon exposure to a high-involvement product, online gossipers are more willing to spread such information through electronic word-of-mouth (eWOM) in search of prestige or fame as a knowledge expert; and (c) this tendency will be more pronounced when they are connected with strong ties (rather than weak ties) and belong to a large network (rather than a small network). An experimental survey was conducted with a scenario method. In total, 818 general consumers participated in the survey. A multivariate analysis of variance (ANOVA) provides empirical support for prediction (1). With regard to predictions (2) and (3), a series of three-way and two-way between-subjective ANOVAs were performed. When a high-involvement product is promoted, gossipers, rather than nongossipers, are more willing to participate in eWOM on an SNS. Furthermore, a significant interaction effect indicates that online gossipers' willingness to particiapte in eWOM would be more pronounced if they belonged to a large network rather than a small network. However, when a low-involvement product is promoted, no interaction effect is found between online gossip and network size. In closing, theoretical and managerial implications are discussed, while important limitations are recognized. PMID:23276259

    The central idea of the Brazilian health system is to prevent the establishment of disease or detect it as early as possible. Prevention and treatment of dental caries are related to behavioral factors, including dietary and oral hygiene habits, which are related to many chronic diseases. Dental health promotion therefore should be fully integrated into broadly based health-promoting strategies and actions such as food and health policies, and general hygiene (including oral hygiene), among others. For decades, a linear relationship between sugar consumption and caries has been observed. Recent data has indicated that this relationship is not as strong as it used to be before the widespread use of fluoride. However, diet is still a key factor acting in the carious process. Oral hygiene is a major aspect when it comes to caries, since dental biofilm is its etiological factor. Oral hygiene procedures are effective in controlling dental caries, especially if plaque removal is performed adequately and associated with fluoride. An alternative to a more efficient biofilm control in occlusal areas is the use of dental sealants, which are only indicated for caries-active individuals. If a cavity is formed as a consequence of the metabolic activity of the biofilm, a restorative material or a sealant can be placed to block access of the biofilm to the oral environment in order to prevent caries progress. The prevention of dental caries based on common risk-factor strategies (diet and hygiene) should be supplemented by more disease-specific policies such as rational use of fluoride, and evidence-based dental health care.

    Full Text Available Mining makes a positive contribution to the economy of Indonesia. Significant earnings accrue through the export of tin, coal, copper, nickel and gold. Of these commodities, gold carries the highest unit value. But not all gold mining is regulated. Indonesia has a significant Artisanal and Small Scale Gold Mining (ASGM industry, defined as any informal and unregulated system of gold mining. These operations are often illegal, unsafe and are environmentally and socially destructive. New technology is needed to support the sustainable exploitation of gold and other precious metal resources in locations where ASGM is currently practised. This technology must be simple, cheap, easy to operate and financially rewarding. A proven option that needs to be promoted is phytoextraction. This is technology where plants are used to extract metals from waste rock, soil or water. These metals can subsequently be recovered from the plant in pure form, and sold or recycled. Gold phytoextraction is a commercially available technology, while international research has shown that phytoextraction will also work for mercury. In the context of ASGM operations, tailings could be contained in specific ‘farming areas’ and cropped using phytoextraction technology. The banning of ASGM operations is not practicable or viable. Poverty would likely become more extreme if a ban were enforced. Instead, new technology options are essential to promote the sustainable development of this industry. Phytoextraction would involve community and worker engagement, education and employment. New skills in agriculture created through application of the technology would be transferrable to the production of food, fibre and timber crops on land adjacent to the mining operations. Phytoextraction could therefore catalyse sustainable development in artisanal gold mining areas throughout Indonesia.

    This is a descriptive-exploratory study using a qualitative approach, conducted in ten municipalities in southern Brazil. Data were obtained by talking to 21 nurses from February to November 2012, through semi-structured interviews using questions to probe their health promotion practices. Data were analyzed through thematic analysis focused on health promotion concepts. We identified four themes about health promotion practices of family health nurses in Brazil: a) training of nurses for health promotion practice was weak; b) nurses formed health promotion groups around diseases and life stages; c) nurses formed groups to meet community needs; and d) nurses used health promotion techniques in group work. These family health nurses were somewhat aware of the importance of health promotion, and how to assist the population against various ailments using some health promotion strategies. The main weaknesses were the lack of understanding about health promotion concepts, and the difficulty of understanding the relevance of its practice, probably attributable to limitations in training. We conclude that primary care groups in Brazil's unified health system could do better in applying health promotion concepts in their practice.

    In Australia, most alcohol is sold as packaged liquor from off-premises retailers, a market increasingly dominated by supermarket chains. Competition between retailers may encourage marketing approaches, for example, discounting, that evidence indicates contribute to alcohol-related harms. This research documented the nature and variety of promotional methods used by two major supermarket retailers to promote alcohol products in their supermarket catalogues. Weekly catalogues from the two largest Australian supermarket chains were reviewed for alcohol-related content over 12 months. Alcohol promotions were assessed for promotion type, product type, number of standard drinks, purchase price and price/standard drink. Each store catalogue included, on average, 13 alcohol promotions/week, with price-based promotions most common. Forty-five percent of promotions required the purchase of multiple alcohol items. Wine was the most frequently promoted product (44%), followed by beer (24%) and spirits (18%). Most (99%) wine cask (2-5 L container) promotions required multiple (two to three) casks to be purchased. The average number of standard drinks required to be purchased to participate in catalogue promotions was 31.7 (SD = 24.9; median = 23.1). The median price per standard drink was $1.49 (range $0.19-$9.81). Cask wines had the lowest cost per standard drink across all product types. Supermarket catalogues' emphasis on low prices/high volumes of alcohol reflects that retailers are taking advantage of limited restrictions on off-premise sales and promotion, which allow them to approach market competition in ways that may increase alcohol-related harms in consumers. Regulation of alcohol marketing should address retailer catalogue promotions. [Johnston R, Stafford J, Pierce H, Daube M. Alcohol promotions in Australian supermarket catalogues.
