    Wagh, Apoorva G; Rakhecha, Veer Chand; Strobl, Makus; Treimer, Wolfgang

    2005-01-01

    Super Ultra-Small Angle Neutron Scattering (SUSANS) studies over wave vector transfers of 10(-4) nm(-1) to 10(-3) nm(-1) afford information on micrometer-size agglomerates in samples. Using a right-angled magnetic air prism, we have achieved a separation of ≈10 arcsec between ≈2 arcsec wide up- and down-spin peaks of 0.54 nm neutrons. The SUSANS instrument has thus been equipped with the polarized neutron option. The samples are placed in a uniform vertical field of 8.8 × 10(4) A/m (1.1 kOe). Several magnetic alloy ribbon samples broaden the up-spin neutron peak significantly over the ±1.3 × 10(-3) nm(-1) range, while leaving the down-spin peak essentially unaltered. Fourier transforms of these SUSANS spectra corrected for the instrument resolution, yield micrometer-range pair distribution functions for up- and down-spin neutrons as well as the nuclear and magnetic scattering length density distributions in the samples.

    Four theorems about four different kinds of entropies for Baker's transformation are presented. The Kolmogorov entropy of Baker's transformation is sensitive to the initial flips by the time. The topological entropy of Baker's transformation is found to be log k. The conditions for the state of Baker's transformation to be forbidden are also derived. The relations among the Shanonn, Kolmogorov, topological and Boltzmann entropies are discussed in details.

  10. Psychoanalytic Interpretation of Blueberries by Susan Gibb

    Directory of Open Access Journals (Sweden)

    Maya Zalbidea Paniagua

    2014-06-01

    Full Text Available Blueberries (2009 by Susan Gibb, published in the ELO (Electronic Literature Organization, invites the reader to travel inside the protagonist’s mind to discover real and imaginary experiences examining notions of gender, sex, body and identity of a traumatised woman. This article explores the verbal and visual modes in this digital short fiction following semiotic patterns as well as interpreting the psychological states that are expressed through poetical and technological components. A comparative study of the consequences of trauma in the protagonist will be developed including psychoanalytic theories by Sigmund Freud, Jacques Lacan and the feminist psychoanalysts: Melanie Klein and Bracha Ettinger. The reactions of the protagonist will be studied: loss of reality, hallucinations and Electra Complex, as well as the rise of defence mechanisms and her use of the artistic creativity as a healing therapy. The interactivity of the hypermedia, multiple paths and endings will be analyzed as a literary strategy that increases the reader’s capacity of empathizing with the speaker.

  11. Susan Sontag — A Forgotten Mother?

    2013-01-01

    Full Text Available The article discusses new and republished translations of Susan Sontag’s work, recently launched by the Karakter publishing house: Regarding the Pan of Others, On Photography, and Against Interpretation and Other Essays. The article focuses on the elements of Sontag’s thought that make her a forgotten mother of feminist and gender theoreticians, as well as such influential critics as Michel Foucault and Roland Barthes. The article points out to continuations of Sontag’s thought in contemporary theoretical and social projects, and to the pertinence of her critical observations on theories based on metaphysics of presence: psychoanalysis, Marxism, or hermeneutics. The article also touches upon history of war photography and related war journalism, and upon the ambivalent quality of imaging of the misery of war. It also present historical and cultural circumstances of the development of Sontag’s thought in the intellectual milieu of New York in the 1960s. The discussion recapitulates the main statements of Sontag’s essays, relating them to a wider theoretical context, which is aimed at a reappraisal of the forgotten intelectual in the history of literature.

    Horwitz, Susan Band; Goldman, I David

    2015-01-01

    Susan Band Horwitz is a Distinguished Professor and holds the Falkenstein Chair in Cancer Research at Albert Einstein College of Medicine in New York. She is co-chair of the Department of Molecular Pharmacology and associate director for therapeutics at the Albert Einstein Cancer Center. After graduating from Bryn Mawr College, Dr. Horwitz received her PhD in biochemistry from Brandeis University. She has had a continuing interest in natural products as a source of new drugs for the treatment of cancer. Her most seminal research contribution has been in the development of Taxol(®). Dr. Horwitz and her colleagues made the discovery that Taxol had a unique mechanism of action and suggested that it was a prototype for a new class of antitumor drugs. Although Taxol was an antimitotic agent blocking cells in the metaphase stage of the cell cycle, Dr. Horwitz recognized that Taxol was blocking mitosis in a way different from that of other known agents. Her group demonstrated that the binding site for Taxol was on the β-tubulin subunit. The interaction of Taxol with the β-tubulin subunit resulted in stabilized microtubules, essentially paralyzing the cytoskeleton, thereby preventing cell division. Dr. Horwitz served as president (2002-2003) of the American Association for Cancer Research (AACR). She is a member of the National Academy of Sciences, the Institute of Medicine, the American Academy of Arts and Sciences, and the American Philosophical Society. She has received numerous honors and awards, including the C. Chester Stock Award from Memorial Sloan Kettering Cancer Center, the Warren Alpert Foundation Prize from Harvard Medical School, the Bristol-Myers Squibb Award for Distinguished Achievement in Cancer Research, the American Cancer Society's Medal of Honor, and the AACR Award for Lifetime Achievement in Cancer Research. The following interview was conducted on January 23, 2014.

  20. Infrared image background modeling based on improved Susan filtering

    Science.gov (United States)

    Yuehua, Xia

    2018-02-01

    When SUSAN filter is used to model the infrared image, the Gaussian filter lacks the ability of direction filtering. After filtering, the edge information of the image cannot be preserved well, so that there are a lot of edge singular points in the difference graph, increase the difficulties of target detection. To solve the above problems, the anisotropy algorithm is introduced in this paper, and the anisotropic Gauss filter is used instead of the Gauss filter in the SUSAN filter operator. Firstly, using anisotropic gradient operator to calculate a point of image's horizontal and vertical gradient, to determine the long axis direction of the filter; Secondly, use the local area of the point and the neighborhood smoothness to calculate the filter length and short axis variance; And then calculate the first-order norm of the difference between the local area of the point's gray-scale and mean, to determine the threshold of the SUSAN filter; Finally, the built SUSAN filter is used to convolution the image to obtain the background image, at the same time, the difference between the background image and the original image is obtained. The experimental results show that the background modeling effect of infrared image is evaluated by Mean Squared Error (MSE), Structural Similarity (SSIM) and local Signal-to-noise Ratio Gain (GSNR). Compared with the traditional filtering algorithm, the improved SUSAN filter has achieved better background modeling effect, which can effectively preserve the edge information in the image, and the dim small target is effectively enhanced in the difference graph, which greatly reduces the false alarm rate of the image.

    baker's asthma is a well-known occupational lung disease which usually develops in adults. We report the case of a two years old boy who suffered from asthma, urticaria and atopic dermatitis for twelve months, whose symptoms were associated to visits to his grandfather's bakery. skin prick tests (SPT) were made to dust mites, moulds, flours, alfa-amylase and egg. It was also determined total IgE and specific IgE antibodies to alfa-amylase and flours. Subsequently, a challenge test was carried out with wheat flour. The SPTs were positive to flours, alfa-amylase and egg. The determination of specific IgE antibodies showed 2.64 kU/L to wheat, 0.79 kU/L to glyadin and 2.98 kU/L to alfa-amylase. The patient developed asthma and rhinitis after manipulating wheat flour for 10 min. we demonstrated a type I hypersensitivity to wheat flour and alfa-amylase in a two years old child by SPT, specific IgE antibodies and challenge test. This case in the childhood equivalent of occupational baker's asthma.

  7. Parallax adjustment algorithm based on Susan-Zernike moments

    Deng, Yan; Zhang, Kun; Shen, Xiaoqin; Zhang, Huiyun

    2018-02-01

    Precise parallax detection through definition evaluation and the adjustment of the assembly position of the objective lens or the reticle are important means of eliminating the parallax of the telescope system, so that the imaging screen and the reticle are clearly focused at the same time. An adaptive definition evaluation function based on Susan-Zernike moments is proposed. First, the image is preprocessed by the Susan operator to find the potential boundary edge. Then, the Zernike moments operator is used to determine the exact region of the reticle line with sub-pixel accuracy. The image definition is evaluated only in this related area. The evaluation function consists of the gradient difference calculated by the Zernike moments operator. By adjusting the assembly position of the objective lens, the imaging screen and the reticle will be simultaneously in the state of maximum definition, so the parallax can be eliminated. The experimental results show that the definition evaluation function proposed in this paper has the advantages of good focusing performance, strong anti-interference ability compared with the other commonly used definition evaluation functions.

  11. [The Durkheim Test. Remarks on Susan Leigh Star's Boundary Objects].

    Science.gov (United States)

    Gießmann, Sebastian

    2015-09-01

    The article reconstructs Susan Leigh Star's conceptual work on the notion of 'boundary objects'. It traces the emergence of the concept, beginning with her PhD thesis and its publication as Regions of the Mind in 1989. 'Boundary objects' attempt to represent the distributed, multifold nature of scientific work and its mediations between different 'social worlds'. Being addressed to several 'communities of practice', the term responded to questions from Distributed Artificial Intelligence in Computer Science, Workplace Studies and Computer Supported Cooperative Work (CSCW), and microhistorical approaches inside the growing Science and Technology Studies. Yet the interdisciplinary character and interpretive flexibility of Star’s invention has rarely been noticed as a conceptual tool for media theory. I therefore propose to reconsider Star's 'Durkheim test' for sociotechnical media practices.

  13. Water-quality effects on Baker Lake of recent volcanic activity at Mount Baker, Washington

    Science.gov (United States)

    Bortleson, Gilbert Carl; Wilson, Reed T.; Foxworthy, B.L.

    1976-01-01

    Increased volcanic activity on Mount Baker, which began in March 1975, represents the greatest known activity of a Cascade Range volcano since eruptions at Lassen Peak, Calif. during 1914-17. Emissions of dust and increased emanations of steam, other gases, and heat from the Sherman Crater area of the mountain focused attention on the possibility of hazardous events, including lava flows, pyroclastic eruptions, avalanches, and mudflows. However, the greatest undesirable natural results that have been observed after one year of the increased activity are an increase in local atmospheric pollution and a decrease in the quality of some local water resources, including Baker Lake. Baker Lake, a hydropower reservoir behind Upper Baker Dam, supports a valuable fishery resource and also is used for recreation. The lake's feedwater is from Baker River and many smaller streams, some of which, like Boulder Creek, drain parts of Mount Baker. Boulder Creek receives water from Sherman Crater, and its channel is a likely route for avalanches or mudflows that might originate in the crater area. Boulder Creek drains only about 5 percent of the total drainage area of Baker Lake, but during 1975 carried sizeable but variable loads of acid and dissolved minerals into the lake. Sulfurous gases and the fumarole dust from Sherman Crater are the main sources for these materials, which are brought into upper Boulder Creek by meltwater from the crater. In September 1973, before the increased volcanic activity, Boulder Creek near the lake had a pH of 6.0-6.6; after the increase the pH ranged as low as about 3.5. Most nearby streams had pH values near 7. On April 29, in Boulder Creek the dissolved sulfate concentration was 6 to 29 times greater than in nearby creeks or in Baker River; total iron was 18-53 times greater than in nearby creeks; and other major dissolved constituents generally 2 to 7 times greater than in the other streams. The short-term effects on Baker Lake of the acidic

  14. Thinking about rumination: the scholarly contributions and intellectual legacy of Susan Nolen-Hoeksema.

    Science.gov (United States)

    Lyubomirsky, Sonja; Layous, Kristin; Chancellor, Joseph; Nelson, S Katherine

    2015-01-01

    Our article reviews and celebrates Susan Nolen-Hoeksema's remarkable contributions to psychological and clinical science, focusing on her vast body of theoretical and empirical work and her influence on colleagues and students. Susan spent her career trying to understand how and why a style of regulating emotions called rumination increases vulnerability to depression and exacerbates and perpetuates negative moods. More broadly, we describe research by Susan and her colleagues on the predictors of depression in childhood and adolescence; gender differences in depression and rumination in adolescence and adulthood; roots, correlates, and adverse consequences of ruminative response styles; and rumination as a transdiagnostic risk factor for not only depression but also a host of psychological disorders, including anxiety, substance abuse, and eating disorders. Susan's intellectual legacy is evident in her impressive publication and citation record, the clinical applications of her work, and the flourishing careers of the students she mentored.

  15. Obituary: James Gilbert Baker, 1914-2005

    Science.gov (United States)

    Baker, Neal Kenton

    2005-12-01

    Dr. James Gilbert Baker, renowned astronomer and optical physicist, died 29 June 2005 at his home in Bedford, New Hampshire at the age of 90. Although his scientific interest was astronomy, his extraordinary ability in optical design led to the creation of hundreds of optical systems that supported astronomy, aerial reconnaissance, instant photography (Polaroid SX70 camera), and the US space programs. He was the recipient of numerous awards for his creative work. He was born in Louisville, Kentucky, on 11 November 1914, the fourth child of Jesse B. Baker and Hattie M. Stallard. After graduating from Louisville DuPont Manual High, he went on to attend the University of Louisville majoring in Mathematics. He became very close to an Astronomy Professor, Dr. Moore, and many times used his telescopes to do nightly observations. While at the university, he built mirrors for his own telescopes and helped form the Louisville Astronomical Society in 1933. At the University of Louisville, he also met his future wife, Elizabeth Katherine Breitenstein of Jefferson County, Kentucky. He received his BA in 1935 at the height of the Depression. He began his graduate work in astronomy at the Harvard College Observatory. After his MA (1936), he was appointed a Junior Fellow (1937-1943) in the Prestigious Harvard Society of Fellows. He received his PhD in 1942 from Harvard in rather an unusual fashion, which is worth retelling. During an Astronomy Department dinner, Dr. Harlow Shapley (the director) asked him to give a talk. According to the "Courier-Journal Magazine", "Dr. Shapley stood up and proclaimed an on-the-spot departmental meeting and asked for a vote on recommending Baker for a Ph.D. on the basis of the 'oral exam' he had just finished. The vote was unanimous." It was at Harvard College Observatory during this first stage of his career that he collaborated with Donald H. Menzel, Lawrence H. Aller, and George H. Shortley on a landmark set of papers on the physical processes

    This article describes the study carried out on a series of oil paintings on canvas from the eighteenth century that were restored at Centro de Produccion e Investigacion en Restauracion y Conservacion Artistica y Bibliografica - Tarea (CEIRCAB-Tarea), Buenos Aires, Argentina: the San Pedro Gonzalez Telmo Sibyls. Experimental study was undertaken to identify inorganic pigments and the technique used in their confection; and, in this way, try to add information about their local origin. Therefore special emphasis was put to infer technologies used in the manufacturing of these paintings. Elemental analysis was performed by total reflection X-ray fluorescence spectrometry (TXRF) and complemented by optical and polarized light microscopy. Microsampling was carefully done over areas of the paintings which were damaged and where a small additional loss will not be noticed. This investigation has shown that a variety of pigments were used, namely earth pigments (red and yellow ochres), white lead, vermilion, etc., and they were used either pure or in mixtures. This characterization helped conservators in their decisions regarding a better understanding of the deterioration processes. In addition, this research about the material composition allowed the art historians and restorers the possibility to obtain information about where, when or by whom The San Pedro Gonzalez Telmo Sibyls may have been painted.

    Supermarket bakers are exposed not only to flour and alpha-amylase but also to other 'improver' enzymes, the nature of which is usually shrouded by commercial sensitivity. We aimed to determine the prevalence of sensitization to 'improver' enzymes in UK supermarket bakers. We examined the prevalence of sensitization to enzymes in 300 bakers, employed by one of two large supermarket bakeries, who had declared work-related respiratory symptoms during routine health surveillance. Sensitization was determined using radioallergosorbent assay to eight individual enzymes contained in the specific 'improver' mix used by each supermarket. The prevalence of sensitization to 'improver' enzymes ranged from 5% to 15%. Sensitization was far more likely if the baker was sensitized also to either flour or alpha-amylase. The prevalence of sensitization to an 'improver' enzyme did not appear to be related to the concentration of that enzyme in the mix. We report substantial rates of sensitization to enzymes other than alpha-amylase in UK supermarket bakers; in only a small proportion of bakers was there evidence of sensitization to 'improver mix' enzymes without sensitization to either alpha-amylase or flour. The clinical significance of these findings needs further investigation, but our findings indicate that specific sensitization in symptomatic bakers may not be identified without consideration of a wide range of workplace antigens. © 2016 John Wiley & Sons A/S.

    Full Text Available In search of plants rich in phenolics in Egypt, Kalanchoe marmorata Baker was subjected to phytochemical study. The preliminary phytochemical screening revealed its richness in phenolics. Fractionation of the lyophilized aqueous extract of the leaves of K. marmorata by different organic solvents successively resulted in the isolation and purification of five compounds from the ethyl acetate soluble fraction. These compounds namely; E1 isorhamnetin-3-O-α-l-1C4-rhamnopyranoside; E2 quercitin; E3 4′-methoxy-myricetin-3-O-α-l-1C4-rhamnopyranoside; E4 Quercitin-3-O-β-d-4C1-glucopyranoside and E5 protocatechuic-4′-O-β-d-4C1-glucopyranoside, were identified by analysis of their spectral data including 1H NMR and 13C NMR.

    1. S-Adenosyl-L-methionine decarboxylase (S-adenosyl-L-methionine carboxy-lyase, EC 4.1.1.50) was purified more than 1100-fold from extracts of Saccharomyces cerevisiae by affinity chromatography on columns of Sepharose containing covalently bound methylglyoxal bis(guanylhydrazone) (1,1'[(methylethanediylidene)dinitrilo]diguanidine) [Pegg, (1974) Biochem J. 141, 581-583]. The final preparation appeared to be homogeneous on polyacrylamide-gel electrophoresis at pH 8.4. 2. S-Adenosylmethionine decarboxylase activity was completely separated from spermidine synthase activity [5'-deoxyadenosyl-(5'),3-aminopropyl-(1),methylsulphonium-salt-putrescine 3-aminopropyltransferase, EC 2.5.1.16] during the purification procedure. 3. Adenosylmethionine decarboxylase activity from crude extracts of baker's yeast was stimulated by putrescine, 1,3-diamino-propane, cadaverine (1,5-diaminopentane) and spermidine; however, the purified enzyme, although still stimulated by the diamines, was completely insensitive to spermidine. 4. Adenosylmethionine decarboxylase has an apparent Km value of 0.09 mM for adenosylmethionine in the presence of saturating concentrations of putrescine. The omission of putrescine resulted in a five-fold increase in the apparent Km value for adenosylmethionine. 5. The apparent Ka value for putrescine, as the activator of the reaction, was 0.012 mM. 6. Methylglyoxal bis(guanylhydrazone) and S-methyladenosylhomocysteamine (decarboxylated adenosylmethionine) were powerful inhibitors of the enzyme. 7. Adenosylmethionine decarboxylase from baker's yeast was inhibited by a number of conventional carbonyl reagents, but in no case could the inhibition be reversed with exogenous pyridoxal 5'-phosphate.

    Baker's cysts are rare cause of peripheral nerve entrapment and only a few cases of tibial nerve entrapment resulting from the popliteal cyst in the calf muscle have been reported in the literature. We present a case of rheumatoid arthritis complicated by a Baker's cyst with a tibial nerve entrapment. It is important to diagnose a Baker's cyst early and to differentiate it from thrombophlebitis, a popliteal aneurysm, tumor or muscle tear to effect optimal therapy and to obviate a potential neuropathy. Prompt recognition of these cases may save the patients unnecessary procedures and delay in treatment.

    Problems with the original Lazy Susan were reported in a previous conference, where the procedure followed for its removal was described. A new Lazy Susan was supplied by the fabricant and it was judged convenient to perform an out-of-core test of the dispositive. A rig was built to produce temperature gradients similar to the ones encountered in the operation at high power levels. After a temperature difference (estimated between 130 o C and 170 o C) between the rotating part and the outside surface was established, the Lazy Susan started to bind. This was reported to the fabricant and it was concluded that a new design was needed and since it would take at least two years before the new unit could be acquired, it was decided to install the Lazy Susan recently supplied. The unit now rotates for approximately 20 minutes when the reactor is operating at 1 MW and then binds. At lower power levels it is operative for longer periods of time. (author)

    Baker's cysts are fluid distensions of the gastrocnemius-semimembranosus bursa and are the most common cystic lesion around the knee. Typically cysts enlarge along intermuscular planes around the knee. We report three cases in which the expanding cyst did not respect these planes and dissected along an intramuscular route as confirmed by MR imaging. Such behaviour by Baker's cysts is hitherto unreported in the literature. Possible mechanisms to account for this phenomenon are discussed. (orig.)

    Baker's yeast is an important additive among the products which improves bread quality and for present time is being produced in different countries by batch, fed batch or continuous cultures. Saccharomyces cerevisiae is used in fermentation of starch in dough, giving a favourable taste and produces a variety of vitamins and proteins. The main ingredient in yeast production is carbon source such as beet molasses, cane molasses, and so on. Since beet molasses has other major function as in high yield alcohol production and also due to the bioenvironmental issues and related wastewater treatment, the use of other carbohydrate sources may be considered. One of these carbohydrate sources is date which is wasted a great deal annually in this country (Iran) . In this study, the capability of date to act as a suitable carbon sources was investigated. The waste date turned into juice and consequently production and growth rate of Sacchromyces cervisiae were studied with this juice. A maximum possible yield of 50% was obtained by the optimum medium (P3), at pH 3.4, 30 degrees C, 1.4 vvm aeration rate and agitation of 500 r/min.

  18. Detection algorithm of infrared small target based on improved SUSAN operator

    Liu, Xingmiao; Wang, Shicheng; Zhao, Jing

    2010-10-01

    The methods of detecting small moving targets in infrared image sequences that contain moving nuisance objects and background noise is analyzed in this paper. A novel infrared small target detection algorithm based on improved SUSAN operator is put forward. The algorithm selects double templates for the infrared small target detection: one size is greater than the small target point size and another size is equal to the small target point size. First, the algorithm uses the big template to calculate the USAN of each pixel in the image and detect the small target, the edge of the image and isolated noise pixels; Then the algorithm uses the another template to calculate the USAN of pixels detected in the first step and improves the principles of SUSAN algorithm based on the characteristics of the small target so that the algorithm can only detect small targets and don't sensitive to the edge pixels of the image and isolated noise pixels. So the interference of the edge of the image and isolate noise points are removed and the candidate target points can be identified; At last, the target is detected by utilizing the continuity and consistency of target movement. The experimental results indicate that the improved SUSAN detection algorithm can quickly and effectively detect the infrared small targets.

  19. Optimization of the flux values in multichannel ceramic membrane microfiltration of Baker`s yeast suspension

    2016-01-01

    Full Text Available The objective of this work was to estimate the effects of the operating parameters on the baker's yeast microfiltration through multichannel ceramic membrane. The selected parameters were transmembrane pressure, suspension feed flow, and initial suspension concentration. In order to investigate the influence and interaction effects of these parameters on the microfiltration operation, two responses have been chosen: average permeate flux and flux decline. The Box-Behnken experimental design and response surface methodology was used for result processing and process optimization. According to the obtained results, the most important parameter influencing permeate flux during microfiltration is the initial suspension concentration. The maximum average flux value was achieved at an initial concentration of 0.1 g/L, pressure around 1.25 bars and a flow rate at 16 L/h. [Projekat Ministarstva nauke Republike Srbije, br. TR 31002

  20. Shuffling cards, factoring numbers and the quantum baker's map

    International Nuclear Information System (INIS)

    Lakshminarayan, Arul

    2005-01-01

    It is pointed out that an exactly solvable permutation operator, viewed as the quantization of cyclic shifts, is useful in constructing a basis in which to study the quantum baker's map, a paradigm system of quantum chaos. In the basis of this operator the eigenfunctions of the quantum baker's map are compressed by factors of around five or more. We show explicitly its connection to an operator that is closely related to the usual quantum baker's map. This permutation operator has interesting connections to the art of shuffling cards as well as to the quantum factoring algorithm of Shor via the quantum order finding one. Hence we point out that this well-known quantum algorithm makes crucial use of a quantum chaotic operator, or at least one that is close to the quantization of the left-shift, a closeness that we also explore quantitatively.

    2001-10-01

    The occurrence of malignant pleural mesothelioma (MPM) among bakers and pastry cooks has never been documented. We detected eight cases of MPM in bakers, pastry cooks, and biscuit cooks engaged in making, baking/cooking, and selling pastry/bread in two hospital-based series (Rome and Orbassano/Turin, Italy; period 1990-1997; 222 cases). Field-investigations revealed asbestos-containing material (ACM) in ovens for baking bread, that were manufactured prior to the 1980s. It is suggested that there is a possible new association of the risk of having worked as a baker or pastry cook and MPM. Presumptive source of exposure to asbestos was the use of asbestos-insulated ovens. Copyright 2001 Wiley-Liss, Inc.

    2006-01-01

    The characteristic stretching and squeezing of chaotic motion is linearized within the finite number of phase space domains which subdivide a classical baker map. Tensor products of such maps are also chaotic, but a more interesting generalized baker map arises if the stacking orders for the factor maps are allowed to interact. These maps are readily quantized, in such a way that the stacking interaction is entirely attributed to primary qubits in each map, if each jth subsystem has Hilbert space dimension D j 2 n j . We here study the particular example of two baker maps that interact via a controlled-not interaction, which is a universal gate for quantum computation. Numerical evidence indicates that the control subspace becomes an ideal Markovian environment for the target map in the limit of large Hilbert space dimension

  11. A “pessoa” de Rudder Baker é realmente incorporada?

    Directory of Open Access Journals (Sweden)

    Jonas Gonçalves Coelho

    2008-06-01

    Full Text Available Some philosophers materialists think, against the dualism of substance, that an embodied mind is only a mind that depends on a body to exist, that is, that the mind doesn’t exist independently of a body. I will take as representative of this very limited point of view about embodiment the ideas of Lynne Baker and her Constitution View. Baker says that she prefers to face the problem of the relationship between persons and bodies than the problem of the relationship between mind and body because this last formulation of the problem implies the idea of a mind distinct and separated of the body while the first is more according of her view of an embodied and situated mind. But the problem is that Baker forgets it when she defines persons in terms of first-person perspective or self-consciousness. Although, Baker says that the self-consciousness depends on structural – a body – and environmental – the situation – conditions, what becomes a self-conscious human person an entity ontologically distinct of the body that constitutes it and of other animals are their realizations like arts, philosophy, science, moral, etc. It looks like that for Baker the self-consciousness is not only a necessary condition but also a sufficient one for that human realizations, while the body fulfill only an indirect role. Against these ideas we can ask: the great realizations that distinguish the human persons of other animals would be possible independently of the biological constitution of our body and its needs?

  13. A New Approach: The Feminist Musicology Studies of Susan McClary and Marcia J. Citron

    Directory of Open Access Journals (Sweden)

    Kimberly Reitsma

    2014-06-01

    Full Text Available One of the currently prevalent analytic approaches in academia is feminist theory and criticism. Its combination with musicology has influenced the field for the past four decades. The goal of the new approach, loosely termed “feminist musicology,” has been to discover, analyze, discuss, and promote the representation of women and the “feminine” essence in various disciplines of music. Today, feminist musicology is highly researched, published in books and journals, and presented as scholarly papers at various musicological conferences around the world. This new approach introduces the ideologies of feminism to the study of music. Susan McClary and Marcia J. Citron are two musicologists who were influenced by these ideologies and have guided the musicological world in this direction of feminist musicology. Both have made serious contributions to the emerging field of feminist musicology. Both researched the ideas of gender musical construction within musical narratives, music as a gendered discourse, and historical and social factors that affected women in music. Although they have met with considerable resistance, Susan McClary and Marcia J. Citron have significantly expanded the scope of musicology through their application of feminist theory.

  14. National Uranium Resource Evaluation: Baker Quadrangle, Oregon and Idaho

    1982-05-01

    The Baker Quadrangle, Oregon, and Idaho, was evaluated to identify areas containing geologic environments favorable for uranium deposits. The criteria used was developed for the National Uranium Resource Evaluation program. Stream-sediment reconnaissance and detailed surface studies were augmented by subsurface-data interpretion and an aerial radiometric survey. Results indicate that lower Pliocene sedimentary rocks in the Lower Powder River Valley-Virtue Flat basin are favorable characteristics, they remain unevaluated because of lack of subsurface data. Tertiary sandstones, possibly present at depth in the Long and Cascade Valleys, also remain unevaluated due to lack of subsurface data. All remaining environments in the Baker Quadrangle are unfavorable for all classes of uranium deposits

    This paper is an historical biography of a fortunate man. It begins with a glimpse of Ross E. Baker's origins in south-western Ontario, watches him going to school and working in Hamilton before joining the Canadian Army and shipping off to Europe to fight in the Second World War. At War's end, the article picks up Dr. Baker as he comes home, starts a family, becomes a chiropractor and sustains a viable practice. Now in the twilight of life, the good doctor is last seen content with his retirement, spending days at his cottage property, reviewing his memoirs and reflecting on the tumult, terror and eventual triumph of the D-Day landing at Normandy.

  16. Allergic airway disease in Italian bakers and pastry makers.

    De Zotti, R; Larese, F; Bovenzi, M; Negro, C; Molinari, S

    1994-08-01

    A survey was carried out on respiratory symptoms and skin prick test response to common allergens (atopy), storage mites, and occupational allergens among 226 bakers and pastry makers from 105 small businesses in northern Italy. Atopy was present in 54 workers (23.4%); 40 workers (17.7%) were skin positive to at least one storage mite, 27 (11.9%) to wheat flour and 17 (7.5%) to alpha-amylase. Work related asthma was reported by 11 (4.9%) workers and rhinoconjunctivitis by 31 (17.7%); 22 workers (10.2%) complained of chronic bronchitis. The distribution of skin prick test results among bakers and among 119 white collar workers did not indicate (by logistic analysis) an increased risk for bakers to skin sensitisation to common allergens, storage mite, or to a group of five flours. Sensitisation to wheat flour, on the other hand, was present only among exposed workers. Skin sensitisation to occupational allergens was significantly associated with atopy (p < 0.001), smoking habit (p = 0.015), and work seniority (p = 0.027). The risk of work related symptoms was associated with sensitisation to wheat or alpha-amylase, and with atopy, but not with sensitisation to storage mites, work seniority, or smoking habit. The results of the study indicate that there is still a significant risk of allergic respiratory disease among Italian bakers. Not only wheat allergens, but also alpha-amylase must be considered as causative agents, although sensitisation to storage mites is not important in the occupational allergic response. Atopy must be regarded as an important predisposing factor for skin sensitisation to occupational allergens and for the onset of symptoms at work. The data confirm that for effective prevention, greater care should be taken not only in limiting environmental exposure, but also in identifying susceptible people.

Moreover, I consider if the silences created by manual processes of classification and retrieval might be surpassed through digital technologies, or if it is possible that new technologies simply create different types of silencing.

  20. Intermittent large amplitude internal waves observed in Port Susan, Puget Sound

    Harris, J. C.; Decker, L.

    2017-07-01

    A previously unreported internal tidal bore, which evolves into solitary internal wave packets, was observed in Port Susan, Puget Sound, and the timing, speed, and amplitude of the waves were measured by CTD and visual observation. Acoustic Doppler current profiler (ADCP) measurements were attempted, but unsuccessful. The waves appear to be generated with the ebb flow along the tidal flats of the Stillaguamish River, and the speed and width of the resulting waves can be predicted from second-order KdV theory. Their eventual dissipation may contribute significantly to surface mixing locally, particularly in comparison with the local dissipation due to the tides. Visually the waves appear in fair weather as a strong foam front, which is less visible the farther they propagate.

    Smith, T A; Smith, P W

    1998-07-01

    This purpose of this study was to examine the relationship between exposure to wheat flour, soya flour and fungal amylase and the development of work-related symptoms and sensitization in bread and cake bakery employees who have regular exposure to these substances. The study populations consisted of 394 bread bakery workers and 77 cake bakery workers whose normal jobs involved the sieving, weighing and mixing of ingredients. The groups were interviewed with the aim of identifying the prevalence, nature and pattern of any work-related respiratory symptoms. They were also skin-prick tested against the common bakery sensitizing agents, i.e., wheat flour, soya flour, rice flour and fungal amylase. The results of personal sampling for sieving, weighing and mixing operations at the bakeries from which the study groups were taken were collated in order to determine typical exposures to total inhalable dust from the ingredients, expressed as 8 hour time-weighted average exposures. Data from the health surveillance and collated dust measurements were compared with the aim of establishing an exposure-response relationship for sensitization. The prevalence of work-related symptoms in bread bakery and cake bakery ingredient handlers was 20.4% and 10.4% respectively. However, in a large proportion of those reporting symptoms in connection with work, the symptoms were intermittent and of short duration. It is considered that the aetiology of such symptoms is likely to be due to a non-specific irritant effect of high total dust levels, rather than allergy. None of the cake bakers and only 3.1% of the bread bakers had symptoms which were thought to be due to allergy to baking ingredients. Using skin-prick testing as a marker of sensitization, the prevalence of positive tests to wheat flour was 6% for the bread bakers and 3% for the cake bakers. Comparable prevalences for soya flour were 7% and 1% respectively. However, the prevalence of positive skin-prick tests to fungal amylase

    Bioremediation of wastewater containing heavy metals is one of the major challenges in environmental biotechnology. Heavy metals are not degraded and as a result they remain in the ecosystem, and pose serious health hazards as it comes in contact with human due to anthropogenic activities. Biological treatment with various microorganisms has been practiced widely in recent past, however, accessing and maintaining the microorganisms have always been a challenge. Microorganisms like Baker's yeast can be very promising biosorbents as they offer high surface to volume ratio, large availability, rapid kinetics of adsorption and desorption and low cost. The main aim of this study is to evaluate the applicability of the biosorption process using baker's yeast. Here we present an experimental investigation of biosorption of Chromium (Cr) from water using commercial Baker's Yeast. It was envisaged that yeast, dead or alive, would adsorb heavy metals, however, operating parameters could play vital roles in determining the removal efficiency. Parameters, such as incubation time, pH, amount of biosorbent and heavy metal concentration were varied to investigate the impacts of those parameters on removal efficiency. Rate of removal was found to be inversely proportional to the initial Cr (+6) concentrations but the removal rate per unit biomass was a weakly dependent on initial Cr(+6) concentrations. Biosorption process was found to be more efficient at lower pH and it exhibited lower removal with the increase in solution pH. The optimum incubation time was found to be between 6-8 hours and optimum pH for the metal ion solution was 2. The effluents produced in leather industries are the major source of chromium pollution in Bangladesh and this study has presented a very cost effective yet efficient heavy metal removal approach that can be adopted for such kind of wastewater.

    The Middle Fork Nooksack River drains the southwestern slopes of the active Mount Baker stratovolcano in northwest Washington State. The river enters Bellingham Bay at a growing delta 98 km to the west. Various types of debris flows have descended the river, generated by volcano collapse or eruption (lahars), glacial outburst floods, and moraine landslides. Initial deposition of sediment during debris flows occurs on the order of minutes to a few hours. Long-lasting, down-valley transport of sediment, all the way to the delta, occurs over a period of decades, and affects fish habitat, flood risk, gravel mining, and drinking water.

    2006-01-01

    In recent years, a growing number of cryptosystems based on chaos have been proposed, many of them fundamentally flawed by a lack of robustness and security. This Letter describes the security weaknesses of a recently proposed cryptographic algorithm with chaos at the physical level based on the baker map. It is shown that the security is trivially compromised for practical implementations of the cryptosystem with finite computing precision and for the use of the iteration number n as the secret key. Some possible countermeasures to enhance the security of the chaos-based cryptographic algorithm are also discussed

    Authors have reported preconcentration of 152 Eu, a long-lived fission product, by yeast cells, Saccharomyces cerevisiae. Gold being a precious metal is used in electroplating, hydrogenation catalyst, etc. Heterogeneous composition of samples and low concentration offers renewed interest in its selective extraction of gold using various extractants. Gold can be recovered from different solutions using various chemical reagents like amines, organophosphorus compounds, and extractants containing sulphur as donor atom, etc. In the present work, two different strains of baker's yeast, Saccharomyces cerevisiae have been used to study the preconcentration of gold at various experimental conditions

  11. Building Abelian Functions with Generalised Baker-Hirota Operators

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available We present a new systematic method to construct Abelian functions on Jacobian varieties of plane, algebraic curves. The main tool used is a symmetric generalisation of the bilinear operator defined in the work of Baker and Hirota. We give explicit formulae for the multiple applications of the operators, use them to define infinite sequences of Abelian functions of a prescribed pole structure and deduce the key properties of these functions. We apply the theory on the two canonical curves of genus three, presenting new explicit examples of vector space bases of Abelian functions. These reveal previously unseen similarities between the theories of functions associated to curves of the same genus.

    Objective: Purpose of this study is to assess sonographic changes and clinical response in different subgroups of Baker's cyst patients with knee osteoarthritis after a single session of ultrasound-guided percutaneous aspiration and corticosteroid injection. Materials and methods: Thirty-two knee osteoarthritis patients (46–85 years, mean 58.97 ± 9.88) with symptomatic Baker's cyst diagnosed at ultrasonography were included in the study. To determine the grade of the symptoms, Visual Analogue Scale was applied. The patients were grouped in two, as simple (n = 24) and complex (n = 8) Baker's cyst. Thirty-two ultrasound-guided cyst aspirations concomitant 1 ml betamethasone injection (24 simple, 8 complex subgroups) were performed. Patients were followed clinically as well as via ultrasonography for 6 months after procedures. Results: A significant decrease in volume of the Baker's cysts after percutaneous treatment was accompanied by a significant clinical improvement. Moreover, the volume reduction of Baker's cyst after the treatment was significantly correlated with the clinical improvement (Pearson correlation coefficient = 0.542, p = 0.001). All 6 Baker's cysts relapsed at ultrasonography were complex type. Furthermore, a comparison of patients with simple Baker's cysts and those with complex Baker's cysts demonstrated no significant change in Visual Analogue Scale scores between two groups (p = 0.061, Mann–Whitney U). No complications (minor or major) occurred secondary to percutaneous treatment. Conclusion: Baker's cysts can be grouped as simple and complex groups via ultrasonography prior to the treatment. Cyst aspiration with ultrasound-guided corticosteroid injection yields clinical improvement and cyst volume reduction in all subgroups of patients with Baker's cyst secondary to knee osteoarthritis.

  14. 'Speaking Kleinian': Susan Isaacs as Ursula Wise and the Inter-War Popularisation of Psychoanalysis.

    2017-10-01

    How did the complex concepts of psychoanalysis become popular in early twentieth-century Britain? This article examines the contribution of educator and psychoanalyst Susan Isaacs (1885-1948) to this process, as well as her role as a female expert in the intellectual and medical history of this period. Isaacs was one of the most influential British psychologists of the inter-war era, yet historical research on her work is still limited. The article focuses on her writing as 'Ursula Wise', answering the questions of parents and nursery nurses in the popular journal Nursery World, from 1929 to 1936. Researched in depth for the first time, Isaacs' important magazine columns reveal that her writing was instrumental in disseminating the work of psychoanalyst Melanie Klein in Britain. Moreover, Isaacs' powerful rebuttals to behaviourist, disciplinarian parenting methods helped shift the focus of caregivers to the child's perspective, encouraging them to acknowledge children as independent subjects and future democratic citizens. Like other early psychoanalysts, Isaacs was not an elitist; she was in fact committed to disseminating her ideas as broadly as possible. Isaacs taught British parents and child caregivers to 'speak Kleinian', translating Klein's intellectual ideas into ordinary language and thus enabling their swift integration into popular discourse.

    Full Text Available The author interprets Susan Silas' Helmbrechts walk (1998-2003, a unique series of forty-five photographs and supplementing visual and textual materials collected during the walk along the route of two hundred and twenty-five miles. The walk repeats the route which in 1945 had to undertake women prisoners from the concentration camp in Helmbrechts near Flossenbürg in their death march to Prachatice in Czech Republic. The pictures Silas takes, the people she meets, and finally the trees, the very materiality of the road become the factors of creating her own, individual memory of the event from the past. Silas selects an object from "the margins of the Holocaust" – a forgotten event that she re-presents by reacting to contemporary objects placed along the route of the event. Silas' work offers an opportunity to critically review the concept of memory landscapes (where is memory located in a landscape? and the phenomenon of dark tourism (is following in the footsteps of the prisoners a kind of pilgrimage, tourism, or therapy?. Silas problematises the question of memory, as well as examines different kinds of non-memory. Her camera is directed at locations that can be termed "the non-sites of memory."

  16. The haunting of Susan Lay: servants and mistresses in seventeenth-century England.

    Science.gov (United States)

    Gowing, Laura

    2002-01-01

    At Easter 1650, Susan Lay, a servant in an Essex alehouse, saw the ghost of her mistress, who had been buried three days before. This article explores the history that lay behind her experience: of sexual relationships with both her master and his son, the births and deaths of two bastard children, and beneath it all, a relationship of antagonism, competition, and intimacy with her mistress. It uses this and other legal records to examine the relationship between women in early modern households, arguing that, while antagonisms between women are typically part of effective patriarchies, the domestic life and social structures of mid seventeenth-century England bound servants and mistresses peculiarly tightly together, giving servants licence to dream of replacing their mistresses and mistresses cause to feel threatened by their servants, and making the competitive relations between women functional to patriarchal order. It suggests, finally, that at this moment in time and in this context, seeing a ghost was the best, perhaps the only, way this servant had to tell a suppressed story and stake a claim to a household that had excluded her.

    Deming Glacier flows from the upper west slopes of Mt. Baker, a stratovolcano in the Cascade Range of Washington, USA. The north and south lateral moraines of Deming Glacier are composed of at least four tills separated by layers of detrital wood and sheared stumps in growth position. The stratigraphy records fluctuations of the glacier during the Holocene. The outer ten rings of an in situ stump from the middle wood layer, which is about 40 m below the north lateral moraine crest and 1.2 km downvalley from the present glacier terminus, yielded an age of 1750 ± 50~~ 14C yr BP [1810-1550 cal yr BP]. The stump revealed at least 300 rings and thus records a period of landscape stability and relatively restricted glaciation for several hundred years prior to ca. 1750 14C yr BP . Samples from the lowest wood layer also have been submitted for radiocarbon dating. Outer rings of detrital wood samples collected from two wood mats exposed in the south lateral moraine, 2.3 km downvalley of the glacier terminus, returned radiocarbon ages of 1600 ± 30~~ 14C yr BP [1550- 1410 cal yr BP] and 430 ± 30~~ 14C yr BP [AD 1420-1620]. These data indicate that Deming Glacier advanced over a vegetated moraine sometime after 1810 cal yr BP to a position less extensive that it achieved at the peak of the Little Ice Age. The glacier then receded before it began its final and most extensive Holocene advance after AD 1420. The older advance is correlative with the 'First Millennium AD' advance, recently recognized throughout western North America. The younger advance coincides with an advance of Mt. Baker's Easton Glacier [AD 1430-1630], and advances of many alpine glaciers elsewhere in western North America. Our data suggest that glaciers on Mt. Baker fluctuated in a similar manner to alpine glaciers in the Coast Mountains of British Columbia and in other mountain ranges of northwest North America during Neoglaciation.

    2013-01-01

    Yeasts rarely encounter ideal physiological conditions during their industrial life span; therefore, their ability to adapt to changing conditions determines their usefulness and applicability. This is especially true for baking strains of Saccharomyces cerevisiae. The success of this yeast in the ancient art of bread making is based on its capacity to rapidly transform carbohydrates into CO2 rather than its unusual resistance to environmental stresses. Moreover, baker's yeast must exhibit efficient respiratory metabolism during yeast manufacturing, which determines biomass yield. However, optimal growth conditions often have negative consequences in other commercially important aspects, such as fermentative power or stress tolerance. This article reviews the genetic and physiological characteristics of baking yeast strains, emphasizing the activation of regulatory mechanisms in response to carbon source and stress signaling and their importance in defining targets for strain selection and improvement.

    Less than 4% of the once extensive Pinus palustris (longleaf pine) ecosystem remains today. Although longleaf pine habitats are recognized for their high species diversity, few published accounts document the vertebrate faunas of remaining tracts. Here we report on the vertebrate species richness of lchauway, an 11,300-ha property in Baker County, GA. The property includes ca. 7300 ha of longleaf pine with native ground cover, along with more than 30 seasonal wetlands and ca. 45 km of riparian habitat associated with Ichawaynochaway Creek, Big Cypress Creek, and the Flint River. The fauna includes 61 species of fish, 31 amphibians, 53 reptiles, 191 birds, and 41 mammals. Despite the relative isolation of the property from other natural ecosystems, the vertebrate fauna of lchauway is remarkably diverse and may offer an example of reference conditions to guide restoration of longleaf pine forests, associated seasonal wetlands, and riparian areas elsewhere in the southeastern U S.

  1. The scholarly rebellion of the early Baker Street Irregulars

    2017-03-01

    Full Text Available This work provides and analyzes an early institutional history of the pioneering Sherlock Holmes American fan club, the Baker Street Irregulars (BSI. Using the publications and records of these devoted Sherlockians, I track the BSI's development from a speakeasy gathering in 1934 to a national organization by the mid-1940s. This growth was built on a foundation of Victorian nostalgia and playful humor. Yet at the same time the members of the Irregulars took their fandom seriously, producing Sherlockian scholarship and creating an infrastructure of journals, conferences, and credentialing that directly mimicked the academy. They positioned themselves in contrast to prevailing scholarly practices of the period, such as New Criticism. I trace both how their fan practices developed over time and how this conflict with the academy led to many of the BSI's defining characteristics.

    Full Text Available Some species of Dyckia Schult. f., including Dyckia brevifolia Baker, are rheophytes that live in the fast-moving water currents of streams and rivers which are subject to frequent flooding, but also period of low water. This study aimed to analyze the leaf epidermis of D. brevifolia in the context of epidermal adaptation to this aquatic plant’s rheophytic habitat. The epidermis is uniseriate, and the cuticle is thickened. The inner periclinal and anticlinal walls of the epidermal cells are thickened and lignified. Stomata are tetracytic, located in the depressions in relation to the surrounding epidermal cells, and covered by peltate trichomes. While the epidermal characteristics of D. brevifolia are similar to those of Bromeliaceae species, this species has made particular adaptations of leaf epidermis in response to its rheophytic environment.

    Vanillin is one of the most widely used flavouring agents, originally obtained from cured seed pods of the vanilla orchid Vanilla planifolia. Currently vanillin is mostly produced via chemical synthesis. A de novo synthetic pathway for heterologous vanillin production from glucose has recently been implemented in baker's yeast, Saccharamyces cerevisiae. In this study we aimed at engineering this vanillin cell factory towards improved productivity and thereby at developing an attractive alternative to chemical synthesis. Expression of a glycosyltransferase from Arabidopsis thaliana in the vanillin producing S. cerevisiae strain served to decrease product toxicity. An in silico metabolic engineering strategy of this vanillin glucoside producing strain was designed using a set of stoichiometric modelling tools applied to the yeast genome-scale metabolic network. Two targets (PDC1 and GDH1) were selected for experimental verification resulting in four engineered strains. Three of the mutants showed up to 1.5 fold higher vanillin β-D-glucoside yield in batch mode, while continuous culture of the Δpdc1 mutant showed a 2-fold productivity improvement. This mutant presented a 5-fold improvement in free vanillin production compared to the previous work on de novo vanillin biosynthesis in baker's yeast. Use of constraints corresponding to different physiological states was found to greatly influence the target predictions given minimization of metabolic adjustment (MOMA) as biological objective function. In vivo verification of the targets, selected based on their predicted metabolic adjustment, successfully led to overproducing strains. Overall, we propose and demonstrate a framework for in silico design and target selection for improving microbial cell factories.

    THE Genetics Society of America's (GSA) George W. Beadle Award honors individuals who have made outstanding contributions to the community of genetics researchers and who exemplify the qualities of its namesake. The 2017 recipient is Susan A. Gerbi, who has been a prominent leader and advocate for the scientific community. In the course of her research on DNA replication, Gerbi helped develop the method of Replication Initiation Point (RIP) mapping to map replication origins at the nucleotide level, improving resolution by two orders of magnitude. RIP mapping also provides the basis for the now popular use of λ-exonuclease to enrich nascent DNA to map replication origins genome-wide. Gerbi's second area of research on ribosomal RNA revealed a conserved core secondary structure, as well as conserved nucleotide elements (CNEs). Some CNEs are universally conserved, while other CNEs are conserved in all eukaryotes but not in archaea or bacteria, suggesting a eukaryotic function. Intriguingly, the majority of the eukaryotic-specific CNEs line the tunnel of the large ribosomal subunit through which the nascent polypeptide exits. Gerbi has promoted the fly Sciara coprophila as a model organism ever since she used its enormous polytene chromosomes to help develop the method of in situ hybridization during her Ph.D. research in Joe Gall's laboratory. The Gerbi laboratory maintains the Sciara International Stock Center and manages its future, actively spreading Sciara stocks to other laboratories. Gerbi has also served in many leadership roles, working on issues of science policy, women in science, scientific training, and career preparation. This is an abridged version of the interview.

    2012-01-01

    Full Text Available The position taken by Haselager, Broens and Quilici Gonzalez in The Importance of Sensing One’s Movements in the World for the Sense of Personal Identity consists in three fundamental theses which can be summarized as follows: (1 The fundamental core of human self-consciousness is not language or thought but the body sense; (2 The traditional dichotomy between external and internal senses is false; (3 There is no prominence of the brain over the rest of the body with regard to the sense of identity that every human being has. This paper aims at showing that – while thesis (1 is perfectly convincing - theses (2 and (3 must be revisited in part since they are too committed to the kind of anti-representationalism proposed by Brooks. In fact, several experimental findings (see above all the vestibulo-ocular reflex show – in contrast to (2 – that the brain distinguishes even at a purely perceptual level between self and external world. Moreover, while other experiments do confirm the “importance”of the body for cognition and the steady interaction between the brain and the body including for the execution of cognitive tasks, they also show – in contrast to (3 – that the influence of bodily movement on the associative areas of the cortex is not directly due to the motor schemata that direct bodily movements but to “higher” brain representations of actions each of which can be executed by different motor schemata.

  16. Coupled skinny baker's maps and the Kaplan-Yorke conjecture

    2013-09-01

    The Kaplan-Yorke conjecture states that for ‘typical’ dynamical systems with a physical measure, the information dimension and the Lyapunov dimension coincide. We explore this conjecture in a neighborhood of a system for which the two dimensions do not coincide because the system consists of two uncoupled subsystems. We are interested in whether coupling ‘typically’ restores the equality of the dimensions. The particular subsystems we consider are skinny baker's maps, and we consider uni-directional coupling. For coupling in one of the possible directions, we prove that the dimensions coincide for a prevalent set of coupling functions, but for coupling in the other direction we show that the dimensions remain unequal for all coupling functions. We conjecture that the dimensions prevalently coincide for bi-directional coupling. On the other hand, we conjecture that the phenomenon we observe for a particular class of systems with uni-directional coupling, where the information and Lyapunov dimensions differ robustly, occurs more generally for many classes of uni-directionally coupled systems (also called skew-product systems) in higher dimensions.

  18. Effect of inhibitors on acid production by baker's yeast.

    Science.gov (United States)

    Sigler, K; Knotková, A; Kotyk, A

    1978-01-01

    Glucose-induced acid extrusion, respiration and anaerobic fermentation in baker's yeast was studied with the aid of sixteen inhibitors. Uranyl(2+) nitrate affected the acid extrusion more anaerobically than aerobically; the complexing of Mg2+ and Ca2+ by EDTA at the membrane had no effect. Inhibitors of glycolysis (iodoacetamide, N-ethylmaleimide, fluoride) suppressed acid production markedly, and so did the phosphorylation-blocking arsenate. Fluoroacetate, inhibiting the citric-acid cycle, had no effect. Inhibition by uncouplers depended on their pKa values: 2,4,6-trinitrophenol (pKa 0.4) less than 2,4-dinitrophenol (4.1) less than azide (4.7) less than 3-chlorophenylhydrazonomalononitrile (6.0). Inhibition by trinitrophenol was only slightly increased by its acetylation. Cyanide and nonpermeant oligomycin showed practically no effect; inhibition by dicyclohexylcarbodiimide was delayed but potent. The concentration profiles of inhibition of acid production differed from those of respiration and fermentation. Thus, though the acid production is a metabolically dependent process, it does not reflect the intensity of metabolism, except partly in the first half of glycolysis.

    2005-12-01

    Norman H. Baker, a key contributor to the foundation of modern stellar pulsation theory and former editor of the "Astronomical Journal", died on 11 October 2005 in Watertown, New York near his beloved summer home in Natural Bridge. He succumbed to complications of Waldenstrom's macroglobulinemia, a bone marrow lymphoma that he had successfully surmounted for twenty-two years. Norm, as he was known to all, was born 23 October 1931 in Fergus Falls, Minnesota to Norman Hodgson and Jeannette (née Lieber) Baker. He attended the University of Minnesota where he met the first of many lifelong astronomical friends, Bill Erickson. He received his BA in 1952. He went on to do his PhD, "Radiation from Particle Interactions which Create Current," at Cornell University under Phil Morrison. He then moved to a postdoctoral position at the Max Planck Institut für Physik und Astrophysik in München with the intent of pursuing his work in plasma physics with Ludwig Biermann and Arnulf Schlüter. However, Rudolf (Rudi) Kippenhan snatched him away to pursue what became his lifelong interest, stellar physics. This was the dawn of the era in which electronic computers were becoming practical for scientific calculations, and Norm immediately adopted this new tool. Indeed, he remained at the forefront of computing technology throughout his life: He was certainly the first member of the Astronomy Department at Columbia to buy a Mac, and was undoubtedly one of the few emeritus professors in the world known by all the administrative staff as the first person to turn to when stumped by a computer problem. Following his first paper with Kippenhan on stellar rotation, Norm turned his attention to stellar pulsations, a topic he would pursue throughout his career. His 1962 paper in "Zeitschrift für Astrophysik" on pulsational models of Cepheids (Baker and Kippenhan 1962, 54, 155) is a classic in the field.

    2008-01-01

    In the laboratory-scale experiments, treatment of baker's yeast production wastewater has been investigated by electrocoagulation (EC) using a batch reactor. Effects of the process variables such as pH, electrode material (Fe and Al), current density, and operating time are investigated in terms of removal efficiencies of chemical oxygen demand (COD), total organic carbon (TOC), turbidity, and operating cost, respectively. The maximum removal efficiencies of COD, TOC and turbidity under optimal operating conditions, i.e., pH 6.5 for Al electrode and pH 7 for Fe electrode, current density of 70 A/m 2 and operating time of 50 min were 71, 53 and 90% for Al electrode and 69, 52 and 56% for Fe electrode, respectively. Al electrode gave 4.4 times higher removal efficiency of turbidity than Fe electrode due to interference from color of dissolved iron. The operating costs for Al and Fe electrodes in terms of $/m 3 or $/kg COD were 1.54 and 0.82, 0.51 and 0.27, respectively

    Kenneth F. Baker (1908-1996) made major contributions to understanding diseases of ornamental plants, seed pathology, soil-borne plant pathogens, biological control, and history of plant pathology. His work set the stage for the success of today's ornamentals and nursery industries. His leadership and writings created the scientific framework for research and teaching on soil-borne plant pathogens and biological control. After B.Sc. and Ph.D. degrees from Washington State University in 1930 and 1934, respectively, and one year as a National Research Council Fellow with B.M. Dugger at Wisconsin, he took jobs in 1935 with the U.S. Department of Agriculture in Nebraska on establishment of shelter belts and 1936-39 with the Pineapple Producers Cooperative Association in Hawaii. He worked on diseases of ornamental plants at the University of California, Los Angeles, starting in 1939, moving to Berkeley in 1961 when the UCLA program closed. He retired in 1975 and moved to Corvallis, OR, as Emeritus Professor, Oregon State University, and Collaborator, U.S. Department of Agriculture, Agricultural Research Service. He spent four sabbatical leaves in Australia, and was elected fellow of the American Association for the Advancement of Science in 1950, fellow of the American Phytopathological Society in 1969, and the Horticultural Hall of Fame in 1976.

    The present study evaluated the antioxidant potential of Vernonia condensata Baker (Asteraceae). Dried and powdered leaves were exhaustively extracted with ethanol by static maceration followed by partition to obtain the hexane, dichloromethane, ethyl acetate, and butanol fractions. Total phenols and flavonoids contents were determined through spectrophotometry and flavonoids were identified by HPLC-DAD system. The antioxidant activity was assessed by DPPH radical scavenging activity, TLC-bioautography, reducing power of Fe+3, phosphomolybdenum, and TBA assays. The total phenolic content and total flavonoids ranged from 0.19 to 23.11 g/100 g and from 0.13 to 4.10 g/100 g, respectively. The flavonoids apigenin and luteolin were identified in the ethyl acetate fraction. The IC50 of DPPH assay varied from 4.28 to 75.10 µg/mL and TLC-bioautography detected the antioxidant compounds. The reducing power of Fe+3 was 19.98 to 336.48 μg/mL, while the reaction with phosphomolybdenum ranged from 13.54% to 32.63% and 56.02% to 135.00% considering ascorbic acid and rutin as reference, respectively. At 30 mg/mL, the ethanolic extract and fractions revealed significant effect against lipid peroxidation. All these data sustain that V. condensata is an important and promising source of bioactive substances with antioxidant activity. PMID:24489987

    A simple algorithm, which exploits the associativity of the BCH formula, and that can be generalized by iteration, extends the remarkable simplification of the Baker-Campbell-Hausdorff (BCH) formula, recently derived by Van-Brunt and Visser. We show that if [X,Y]=uX+vY+cI, [Y,Z]=wY+zZ+dI, and, consistently with the Jacobi identity, [X,Z]=mX+nY+pZ+eI, then exp (X)exp (Y)exp (Z)=exp (aX+bY+cZ+dI) where a, b, c and d are solutions of four equations. In particular, the Van-Brunt and Visser formula exp (X)exp (Z)=exp (aX+bZ+c[X,Z]+dI) extends to cases when [X,Z] contains also elements different from X and Z. Such a closed form of the BCH formula may have interesting applications both in mathematics and physics. As an application, we provide the closed form of the BCH formula in the case of the exponentiation of the Virasoro algebra, with SL{sub 2}(ℂ) following as a subcase. We also determine three-dimensional subalgebras of the Virasoro algebra satisfying the Van-Brunt and Visser condition. It turns out that the exponential form of SL{sub 2}(ℂ) has a nice representation in terms of its eigenvalues and of the fixed points of the corresponding Möbius transformation. This may have applications in Uniformization theory and Conformal Field Theories.

    Full Text Available Susan Magoffin, la jeune épouse d’un commerçant de la piste de Santa Fe, accompagna son mari en 1846 pour un voyage où la caravane suivait de près l’Armée de l’Ouest et pendant lequel elle tint un journal. Cet article traite des 37 jours que dura la pause de la caravane à Santa Fe et aborde plus spécifiquement la façon dont l’auteur appréhendait l’altérité dans un environnement inhabituel et parfois dangereux. Pour apprécier la valeur du témoignage, je combine une analyse du discours avec une évaluation statistique du contenu. La description, parfois naïve, de Santa Fe sous l’occupation américaine illustre les raisons de la guerre contre le Mexique. En tant qu’agent de la destinée manifeste, Susan Magoffin admirait le général Kearny en lui attribuant des qualités surhumaines et en participant à ses efforts de propagande. Alors qu’elle était enracinée dans sa classe et sa culture, elle voyait la population mexicaine et les Amérindiens avec un esprit ouvert bien que ses motifs pour apprendre l’espagnol, ainsi que le métier de commerçante, avaient une fonction plus prosaïque.

    By adjusting the mixing order of ingredients in traditional formula, an innovative bread making process was developed. The effect of salt-stressed Baker's yeast on bread dough of different sugar levels was investigated. Baker's yeast was stressed in 7% salt solution then mixed into dough, which was then evaluated for fermentation time, dough fermentation producing gas, dough expansion, bread specific volumes, and sensory and physical properties. The results of this study indicated that salt-stressed Baker's yeast shortened fermentation time in 16% and 24% sugar dough. Forty minutes of salt stress produced significant amount of gas and increased bread specific volumes. The bread was softer and significantly improved sensory properties for aroma, taste, and overall acceptability were obtained.

    The digital Baker map is widely used in different kinds of cryptosystems, especially for image encryption. However, any chaotic map which is realized on the finite precision device (e.g. computer) will suffer from dynamical degradation, which refers to short cycle lengths, low complexity and strong correlations. In this paper, a novel double perturbation method is proposed for reducing the dynamical degradation of the digital Baker map. Both state variables and system parameters are perturbed by the digital logistic map. Numerical experiments show that the perturbed Baker map can achieve good statistical and cryptographic properties. Furthermore, a new image encryption algorithm is provided as a simple application. With a rather simple algorithm, the encrypted image can achieve high security, which is competitive to the recently proposed image encryption algorithms.

    Objective: Purpose of this study is to assess sonographic changes and clinical response in different subgroups of Baker's cyst patients with knee osteoarthritis after a single session of ultrasound-guided percutaneous aspiration and corticosteroid injection. Materials and methods: Thirty-two knee osteoarthritis patients (46-85 years, mean 58.97 {+-} 9.88) with symptomatic Baker's cyst diagnosed at ultrasonography were included in the study. To determine the grade of the symptoms, Visual Analogue Scale was applied. The patients were grouped in two, as simple (n = 24) and complex (n = 8) Baker's cyst. Thirty-two ultrasound-guided cyst aspirations concomitant 1 ml betamethasone injection (24 simple, 8 complex subgroups) were performed. Patients were followed clinically as well as via ultrasonography for 6 months after procedures. Results: A significant decrease in volume of the Baker's cysts after percutaneous treatment was accompanied by a significant clinical improvement. Moreover, the volume reduction of Baker's cyst after the treatment was significantly correlated with the clinical improvement (Pearson correlation coefficient = 0.542, p = 0.001). All 6 Baker's cysts relapsed at ultrasonography were complex type. Furthermore, a comparison of patients with simple Baker's cysts and those with complex Baker's cysts demonstrated no significant change in Visual Analogue Scale scores between two groups (p = 0.061, Mann-Whitney U). No complications (minor or major) occurred secondary to percutaneous treatment. Conclusion: Baker's cysts can be grouped as simple and complex groups via ultrasonography prior to the treatment. Cyst aspiration with ultrasound-guided corticosteroid injection yields clinical improvement and cyst volume reduction in all subgroups of patients with Baker's cyst secondary to knee osteoarthritis.

    Saccharomyces cerevisiae, the conventional baker's yeast, remains the most domesticated yeast monopolizing the baking industry. Its rapid consumption of sugars and production of CO 2 are the most important attributes required to leaven the dough. New research attempts highlight that these attributes are not unique to S. cerevisiae, but also found in several non-conventional yeast species. A small number of these yeast species with similar properties have been described, but remain poorly studied. They present a vast untapped potential for the use as leavening agents and flavor producers due to their genetic and phylogenetic diversity. We assessed the potential of several non-conventional yeasts as leavening agents and flavor producers in dough-like conditions in the presence of high sugar concentrations and stressful environments mimicking conditions found in flour dough. We tested the capabilities of bread leavening and aroma formation in a microbread platform as well as in a bakery setup. Bread leavened with Kazachstania gamospora and Wickerhamomyces subpelliculosus had better overall results compared to control baker's yeast. In addition, both displayed higher stress tolerance and broader aroma profiles than the control baker's yeast. These attributes are important in bread and other farinaceous products, making K. gamospora and W. subpelliculosus highly applicable as alternative baker's yeasts. Copyright © 2017 Elsevier B.V.

  19. Reconstructing streamflow variation of the Baker River from tree-rings in Northern Patagonia since 1765

    The understanding of the long-term variation of large rivers streamflow with a high economic and social relevance is necessary in order to improve the planning and management of water resources in different regions of the world. The Baker River has the highest mean discharge of those draining both slopes of the Andes South of 20°S and it is among the six rivers with the highest mean streamflow in the Pacific domain of South America (1100 m3 s-1 at its outlet). It drains an international basin of 29,000 km2 shared by Chile and Argentina and has a high ecologic and economic value including conservation, tourism, recreational fishing, and projected hydropower. This study reconstructs the austral summer - early fall (January-April) streamflow for the Baker River from Nothofagus pumilio tree-rings for the period 1765-2004. Summer streamflow represents 45.2% of the annual discharge. The regression model for the period (1961-2004) explains 54% of the variance of the Baker River streamflow (R2adj = 0.54). The most significant temporal pattern in the record is the sustained decline since the 1980s (τ = -0.633, p = 1.0144 ∗ 10-5 for the 1985-2004 period), which is unprecedented since 1765. The Correlation of the Baker streamflow with the November-April observed Southern Annular Mode (SAM) is significant (1961-2004, r = -0.55, p < 0.001). The Baker record is also correlated with the available SAM tree-ring reconstruction based on other species when both series are filtered with a 25-year spline and detrended (1765-2004, r = -0.41, p < 0.01), emphasizing SAM as the main climatic forcing of the Baker streamflow. Three of the five summers with the highest streamflow in the entire reconstructed record occurred after the 1950s (1977, 1958 and 1959). The causes of this high streamflow events are not yet clear and cannot be associated with the reported recent increase in the frequency of glacial-lake outburst floods (GLOFs). The decreasing trend in the observed and reconstructed

    New stratigraphic and paleontologic data indicate that ophiolitic melange windows in the Olds Ferry terrane of eastern Oregon contain limestone blocks and chert that are somewhat different in age than those present in the adjacent Baker terrane melange. The melange windows in the Olds Ferry terrane occur as inliers in the flyschoid Early and Middle Jurassic age Weatherby Formation, which depositionally overlies the contact between the melange-rich Devonian to Upper Triassic rocks of the Baker terrane on the north, and Upper Triassic and Early Jurassic volcanic arc rocks of the Huntington Formation on the south. The Baker terrane and Huntington Formation represent fragments of a subduction complex and related volcanic island arc, whereas the Weatherby Formation consists of forearc basin sedimentary deposits. The tectonic blocks in the melange windows of the Weatherby Formation (in the Olds Ferry terrane) are dated by scarce biostratigraphic evidence as Upper Pennsylvanian to Lower Permian and Upper Triassic. In contrast, tectonic blocks of limestone in theBaker terrane yield mostly fusulinids and small foraminifers of Middle Pennsylvanian Moscovian age at one locality.Middle Permian (Guadalupian) Tethyan fusulinids and smaller foraminifers (neoschwagerinids and other Middle Permian genera) are present at a few other localities. Late Triassic conodonts and bryozoans are also present in a few of the Baker terrane tectonic blocks. These limestone blocks are generally embedded in Permian and Triassic radiolarian bearing chert or argillite. Based on conodont, radiolarian and fusulinid data, the age limits of the meange blocks in the Weatherby Formation range from Pennsylvanian to Late Triassic.

  2. ‘Speaking Kleinian’: Susan Isaacs as Ursula Wise and the Inter-War Popularisation of Psychoanalysis

    Science.gov (United States)

    Shapira, Michal

    2017-01-01

    How did the complex concepts of psychoanalysis become popular in early twentieth-century Britain? This article examines the contribution of educator and psychoanalyst Susan Isaacs (1885–1948) to this process, as well as her role as a female expert in the intellectual and medical history of this period. Isaacs was one of the most influential British psychologists of the inter-war era, yet historical research on her work is still limited. The article focuses on her writing as ‘Ursula Wise’, answering the questions of parents and nursery nurses in the popular journal Nursery World, from 1929 to 1936. Researched in depth for the first time, Isaacs’ important magazine columns reveal that her writing was instrumental in disseminating the work of psychoanalyst Melanie Klein in Britain. Moreover, Isaacs’ powerful rebuttals to behaviourist, disciplinarian parenting methods helped shift the focus of caregivers to the child’s perspective, encouraging them to acknowledge children as independent subjects and future democratic citizens. Like other early psychoanalysts, Isaacs was not an elitist; she was in fact committed to disseminating her ideas as broadly as possible. Isaacs taught British parents and child caregivers to ‘speak Kleinian’, translating Klein’s intellectual ideas into ordinary language and thus enabling their swift integration into popular discourse.

    Kenny, Michael G

    2004-09-01

    In 1974 a British biologist, John Randal Baker (1900-1984), published a large and controversial book simply entitled Race that reiterated persistent eugenicist themes concerning the relation between race, intelligence, and progress. The history of Baker's book is a case study in the politics of scientific publishing, and his ideas influenced scholars associated with later works such as The Bell Curve. Baker, a student of Julian Huxley, was a longtime participant in the British eugenics movement and opponent of what he took to be a facile belief in human equality. In 1942, together with Michael Polanyi, he founded the Society for Freedom in Science to oppose those who advocated the central planning of scientific research. Baker's eugenics, political activities, and views on race express an elitist individualism, associated with the conservative wing of the eugenics movement, that this paper explores in the context of his career as a whole.

    2-Phenylethanol (PEA), an important alcohol derived from phenylalanine, is involved in aroma and flavour of bakers' products. Four spontaneous mutants of an industrial bakers' yeast, V1 strain, were isolated for their resistance to p-fluoro-DL-phenylalanine (PFP), a toxic analogue of L-phenylalanine. Mutants overproduced this amino acid and showed variations in their internal pool for several other amino acids. Moreover, a rise in PEA production after growth in industrial medium (MAB) was observed in three of the mutants, although their growth and fermentative capacities were slightly impaired. However, concentration of PEA remained higher during dough fermentation and also after baking, thus improving taste and aroma in bread. Copyright © 2014 Elsevier B.V. All rights reserved.

    1977-01-01

    In March 1975 Mount Baker showed a large increase in thermal emission, which has persisted for more than 1 year. Fumarole ejecta accompanied the thermal activity from March to September, but the ejecta had no constituents that suggest a magmatic source. Estimates of that part of the total heat flux that would account for the observed snow and ice loss show that the heat-flow increase was roughly one order of magnitude, from about 2 megawatts at 10 watts per square meter, averaged over Sherman Crater before 1975, to about 30 megawatts at 180 watts per square meter, during 1975. Almost half of the glacier that occupied the basin of Sherman Crater was melted in 1975. The new activity generated great concern among the public and the government agencies responsible for geological evaluation of potential hazards and for protection of life and property. The past geologic history, current topography, rock alteration, and location of major fumarolic activity indicate that large rock avalanches and mudflows on the east slope in Boulder Creek valley are the potential hazards of most significance related to present conditions. The most probable types of large mass movements would be mudflows, having speeds of as much as 50 kilometers per hour, that would originate from mixtures of snow, ice, and melt water and avalanches of structurally weak clay-rich rocks that make up the rim of Sherman Crater. Similar mudflows from the volcano have traveled at least 12 kilometers 8 times during the past 10,000 years. A possible worst case event, however, might be a larger, air-cushioned avalanche of as much as 20 to 30 million cubic meters that could hit Baker Lake at speeds of more than 300 kilometers per hour and generate a wave of water large enough to overtop Upper Baker Dam. At least 30 million cubic meters of potentially unstable material occurs as hydrothermally altered remnants of the rim of Sherman Crater and could provide the required volume for the estimated worst case event or

    Full Text Available Abstract Melicope madagascariensis (Rutaceae is an endemic plant species of Madagascar that was first classified as a member of the genus Euodia J. R. & G. Forst (Rutaceae under the scientific name Euodia madagascariensis Baker. Based on morphological characteristics, Thomas Gordon Hartley taxonomically revised E. madagascariensis Baker to be M. madagascariensis (Baker T.G. Hartley. Chemotaxonomical studies have long been used to help the identification and confirmation of taxonomical classification of plant species and botanicals. Aiming to find more evidences to support the taxonomical revision performed on E. madagascariensis, we carried out phytochemical investigation of two samples of the plant. Fractionation of the ethanol extracts prepared from two stem bark samples of M. madagascariensis (Baker T.G. Hartley led to the isolation of seven known furoquinoline alkaloids 1–7 and two known methoxyflavones 8 and 9. The presence of furoquinoline alkaloids and methoxyflavones in the title species is in agreement with its taxonomic transfer from Euodia to Melicope. Antiprotozoal evaluation of the isolated compounds showed that 6-methoxy-7-hydroxydictamnine (heliparvifoline, 3 showed weak antimalarial activity (IC50 = 35 µM against the chloroquine-resistant strain Dd2 of Plasmodium falciparum.

    Some studies have suggested increased lung cancer risks among bakers, however the results overall were inconsistent. The authors studied lung cancer risks among bakers and baking-related occupations in the SYNERGY pooled case-control database from 16 countries. Occupation in a baking-related job was identified from the subjects' job histories. ORs adjusted for log(age), study centre, smoking behaviour and ever employment in a job with known exposure to occupational lung carcinogens were calculated by unconditional logistic regression. Findings were stratified by sex, histological subtype of lung cancer and smoking status. 19 366 cases (15 606 men) and 23 670 control subjects (18 528 men) were included. 473 cases (415 men, 58 women) and 501 controls (437 men, 64 women) had ever worked in baking or a related job. We did not observe an increased risk for men in baking (OR 1.01; 95% CI 0.86 to 1.18). No linear trends were observed for duration of employment. Some results suggested increased lung cancer risks for women, for example, for working as a baker for >30 years and in never-smokers, but after exclusion of one study these increased risks disappeared. The findings from this study do not suggest increased lung cancer risks in baking-related professions.

    We describe one case of baker's yeast true allergy in a boy with previously diagnosed mite-allergy and atopic dermatitis. At the age of 6, being atopic dermatitis and rhinitis well controlled by drugs, he began to experience generalized urticaria and asthma after eating pizza and bread, but only fresh from the oven. The diagnostic workup revealed single sensitization to baker's yeast (Saccharomyces cerevisiae), and a severe systemic reaction also occurred during the prick-by-prick procedure. After discussing with parents, no special dietary restriction was suggested but the use of autoinjectable adrenaline and on demand salbutamol. A diary of symptoms was recorded by means of a visual-analog scale. During the subsequent 2 years, the severity of symptoms was progressively reduced, and presently urticaria has disappeared. Only cough persists, invariantly after eating just-baked and yeast-containing foods. If bread, pizza and cakes are ate more than one hour after preparation, no symptom occur at all. Baker's yeast is a common component of everyday diet and it usually acts as an allergen only by the inhalatory route. We speculate that the continuous exposure to saccharomyces in foods may have lead to an immunotolerance with a progressive reduction of symptoms, whereas why the allergens is active only in ready-baked foods remains unexplained.

    The study aims to isolate the yeast strains that could be used effectively as baker's yeast and compare them with the commercial baker's yeast available in the market of Nepal. A total of 10 samples including locally available sources like fruits, Murcha, and a local tree "Dar" were collected from different localities of Bhaktapur, Kavre, and Syangja districts of Nepal, respectively. Following enrichment and fermentation of the samples, 26 yeast strains were isolated using selective medium Wallerstein Laboratory Nutrient Agar. From the differential tests which included morphological and microscopic observation and physiological and biochemical characterization such as nitrate reduction and lactose utilization tests, 8 strains were selected as possible Saccharomyces strain. The selected strains were further assessed for their efficient leavening ability by tests such as ethanol tolerance, osmotolerance, invertase test, and stress exclusion test. The three most potent strains ENG, MUR3B, and SUG1 isolated from grape, Murcha, and sugarcane, respectively, were used in the fermentation and baking of dough. These strains also carried a possibility of being used as industrial baker's yeast.

    Purpose: Traditional extended SSD total body irradiation (TBI) techniques can be problematic in terms of patient comfort and/or dose uniformity. This work aims to develop a comfortable TBI technique that achieves a uniform dose distribution to the total body while reducing the dose to organs at risk for complications. Methods: To maximize patient comfort, a lazy Susan-like couch top immobilization system which rotates about a pivot point was developed. During CT simulation, a patient is immobilized by a Vac-Lok bag within the body frame. The patient is scanned head-first and then feet-first following 180° rotation of the frame. The two scans are imported into the Pinnacle treatment planning system and concatenated to give a full-body CT dataset. Treatment planning matches multiple isocenter volumetric modulated arc (VMAT) fields of the upper body and multiple isocenter parallel-opposed fields of the lower body. VMAT fields of the torso are optimized to satisfy lung dose constraints while achieving a therapeutic dose to the torso. The multiple isocenter VMAT fields are delivered with an indexed couch, followed by body frame rotation about the pivot point to treat the lower body isocenters. The treatment workflow was simulated with a Rando phantom, and the plan was mapped to a solid water slab phantom for point- and film-dose measurements at multiple locations. Results: The treatment plan of 12Gy over 8 fractions achieved 80.2% coverage of the total body volume within ±10% of the prescription dose. The mean lung dose was 8.1 Gy. All ion chamber measurements were within ±1.7% compared to the calculated point doses. All relative film dosimetry showed at least a 98.0% gamma passing rate using a 3mm/3% passing criteria. Conclusion: The proposed patient comfort-oriented TBI technique provides for a uniform dose distribution within the total body while reducing the dose to the lungs

    Previously reported self-cloning procedures for breeding of industrial yeast strains require DNA from other strains, plasmid DNA, or mutagenesis. Therefore, we aimed to construct a self-cloning baker's yeast strain that exhibits freeze tolerance via an improved self-cloning procedure. We first disrupted the URA3 gene of a prototrophic baker's yeast strain without the use of any marker gene, resulting in a Δura3 homozygous disruptant. Then, the URA3 gene of the parental baker's yeast strain was used as a selection marker to introduce the constitutive TDH3 promoter upstream of the PDE2 gene encoding high-affinity cyclic AMP phosphodiesterase. This self-cloning procedure was performed without using DNA from other Saccharomyces cerevisiae strains, plasmid DNA, or mutagenesis and was therefore designated an intra-strain self-cloning procedure. Using this self-cloning procedure, we succeeded in producing self-cloning baker's yeast strains that harbor the TDH3p-PDE2 gene heterozygously and homozygously, designated TDH3p-PDE2 hetero and TDH3p-PDE2 homo strains, respectively. These self-cloning strains expressed much higher levels of PDE2 mRNA than the parental strain and exhibited higher viability after freeze stress, as well as higher fermentation ability in frozen dough, when compared with the parental strain. The TDH3p-PDE2 homo strain was genetically more stable than the TDH3p-PDE2 hetero strain. These results indicate that both heterozygous and homozygous strains of self-cloning PDE2-overexpressing freeze-tolerant strains of industrial baker's yeast can be prepared using the intra-strain self-cloning procedure, and, from a practical viewpoint, the TDH3p-PDE2 homo strain constructed in this study is preferable to the TDH3p-PDE2 hetero strain for frozen dough baking.

    High‐resolution helicopter magnetic and electromagnetic (HEM) data flown over the rugged, ice‐covered Mt. Adams, Mt. Baker and Mt. Rainier volcanoes (Washington), reveal the distribution of alteration, water and ice thickness essential to evaluating volcanic landslide hazards. These data, combined with geological mapping and rock property measurements, indicate the presence of appreciable thicknesses (>500 m) of water‐saturated hydrothermally altered rock west of the modern summit of Mount Rainier in the Sunset Amphitheater region and in the central core of Mount Adams north of the summit. Alteration at Mount Baker is restricted to thinner (<300 m) zones beneath Sherman Crater and the Dorr Fumarole Fields. The EM data identified water‐saturated rocks from the surface to the detection limit (100–200 m) in discreet zones at Mt. Rainier and Mt Adams and over the entire summit region at Mt. Baker. The best estimates for ice thickness are obtained over relatively low resistivity (<800 ohm‐m) ground for the main ice cap on Mt. Adams and over most of the summit of Mt. Baker. The modeled distribution of alteration, pore fluids and partial ice volumes on the volcanoes helps identify likely sources for future alteration‐related debris flows, including the Sunset Amphitheater region at Mt. Rainier, steep cliffs at the western edge of the central altered zone at Mount Adams and eastern flanks of Mt. Baker.

    The interaction of the enzyme-substrate complex with methyl phosphate, O-phosphoethanolamine, O-phosphopropanolamine, N-acetylphosphoserine, and phosphoglyolic acid, as well as pyrophosphatase, modified by monoesters of phosphoric acid, with pyrophosphate and tripolyphosphate, was investigated. It was shown that the enzyme containing the substrate in the active site does not react with monophosphates, but modified pyrophosphatase entirely retains the ability to bind polyanions to the regulatory site. It is concluded that the inactivation of baker's yeast inorganic pyrophosphatase by monoesters of phosphoric acid, which are affinity inhibitors of it, is the result of modification of the active site of the enzyme

    Historically, neurologists were not involved in the day-to-day management of critically ill patients with bulbar poliomyelitis, but some were. The major contributions of 3 neurologists-W. Ritchie Russell, A.B. Baker, and Fred Plum-in the respiratory management of poliomyelitis have not been recognized. Russell's work was instrumental in identifying multiple types of poliomyelitis defined by their respiratory needs, and he advised treatment that varied from simple postural drainage to use of respirators. He participated in the development of the Radcliffe respiratory pump. Baker recognized the essential involvement of the vagal nerve in respiratory distress, but also observed that involvement of vital centers without cranial nerve involvement would lead to irregular and shallow respiration in some patients and in others with marked dysautonomic features. A similar finding of central involvement of respiration was noted by Plum, who also stressed the importance of hypercapnia. Plum emphasized measurements of vital capacity and techniques to minimize trauma with suctioning after tracheostomy. These 3 neurologists understood the importance of airway and ventilator management, which is currently one of the many pillars of neurocritical care. © 2016 American Academy of Neurology.

    A survey was carried out on respiratory symptoms and skin prick response to common allergens, storage mite and occupational allergens. Among 178 symptomatics bakers and pastry workers from small businesses in western France, only 65 people underwent skin prick and specific-IgE. 12 (18%) workers were skin positive to at least one common or occupational allergens. The more often skin positive were D. Ptero. mite 36 (57%); Alpha amylase 23 (35%); wheat flour 17 (26%); saccharomyces cerevisiae 16 (25%); Ephestia 15 (24%). The sensitivity of skin test was better than specific IgE for D. Ptero. Mite 36 (57%); and Alpha amylase 23 (35%). The sensitivity of specific IgE was better than skin test for wheat flour 26 (45%) and rye flour 23 (40%). Occurrence of skin positive to occupational allergen among symptomatics with rhinitis and asthma is much more frequent in workers with skin positive to common allergens (40/36) than in workers with skin negative (8/20). Atopy must be regarded as an important predisposing factor for skin sensitisation to occupational allergens. We conclude in the necessity of a standardised allergologic exploration to be done in symptomatics bakers.

    Baker's yeast, Saccharomyces cerevisiae, is a key component in bread baking. Total of 12 commercial baker's yeast and 2 hybrid strains were compared using traditional quality parameters. Total of 5 strains with high leavening power and the 2 hybrid strains were selected and evaluated for their alpha-amylase, maltase, glucoamylase enzymes, and compared using random amplified polymorphic DNA (RAPD). The results revealed that all selected yeast strains have a low level of alpha-amylase and a high level of maltase and glucoamylase enzymes. Meanwhile, the Egyptian yeast strain (EY) had the highest content of alpha-amylase and maltase enzymes followed by the hybrid YH strain. The EY and YH strains have the highest content of glucoamylase enzyme almost with the same level. The RAPD banding patterns showed a wide variation among commercial yeast and hybrid strains. The closely related Egyptian yeast strains (EY and AL) demonstrated close similarity of their genotypes. The 2 hybrid strains were clustered to Turkish and European strains in 1 group. The authors conclude that the identification of strains and hybrids using RAPD technique was useful in determining their genetic relationship. These results can be useful not only for the basic research, but also for the quality control in baking factories. © 2012 Institute of Food Technologists®

  3. A novel image encryption scheme based on the ergodicity of baker map

    Thanks to the exceptionally good properties in chaotic systems, such as sensitivity to initial conditions and control parameters, pseudo-randomness and ergodicity, chaos-based image encryption algorithms have been widely studied and developed in recent years. A novel digital image encryption scheme based on the chaotic ergodicity of Baker map is proposed in this paper. Different from traditional encryption schemes based on Baker map, we permute the pixel positions by their corresponding order numbers deriving from the approximating points in one chaotic orbit. To enhance the resistance to statistical and differential attacks, a diffusion process is suggested as well in the proposed scheme. The proposed scheme enlarges the key space significantly to resist brute-force attack. Additionally, the distribution of gray values in the cipher-image has a random-like behavior to resist statistical analysis. The proposed scheme is robust against cropping, tampering and noising attacks as well. It therefore suggests a high secure and efficient way for real-time image encryption and transmission in practice.

    Mount Baker volcano displayed a short interval of seismically-quiescent thermal unrest in 1975, with high emissions of magmatic gas that slowly waned during the following three decades. The area of snow-free ground in the active crater has not returned to pre-unrest levels, and fumarole gas geochemistry shows a decreasing magmatic signature over that same interval. A relative microgravity survey revealed a substantial gravity increase in the ~30 years since the unrest, while deformation measurements suggest slight deflation of the edifice between 1981-83 and 2006-07. The volcano remains seismically quiet with regard to impulsive volcano-tectonic events, but experiences shallow (10 km) long-period earthquakes. Reviewing the observations from the 1975 unrest in combination with geophysical and geochemical data collected in the decades that followed, we infer that elevated gas and thermal emissions at Mount Baker in 1975 resulted from magmatic activity beneath the volcano: either the emplacement of magma at mid-crustal levels, or opening of a conduit to a deep existing source of magmatic volatiles. Decadal-timescale, multi-parameter observations were essential to this assessment of magmatic activity.

    Our previous study has revealed that the spirostanol saponins isolated from the rhizomes of Rohdea chinensis (Baker) N. Tanaka (synonym Tupistra chinensis Baker) (Convallariaceae) (a reputed folk medicine) exhibited potent antiproliferative activity. However, the underlying mechanism of purified saponins remains unclear. More studies are necessary to assess the apoptosis and autophagy activities of the saponins from R. chinensis and clarify their antiproliferative mechanisms. The present study certificated the potential antiproliferative activity and mechanism of 5β-spirost-25(27)-en-1β,3β-diol-1-O-α-L-rhamnopyranosyl-(1→2)- β-D-xylopyranosyl-3-O-α-L-rhamnopyranoside (SPD), a spirostanol saponin from R. chinensis, against human acute promyelocytic leukemia cells (HL-60). The antiproliferative activity of SPD in vitro was evaluated by MTT assay compared with cis-dichlorodiammineplatinum (II). The autophagic activity was assessed using MDC staining and western blot, cell apoptosis inspection was detected by Annexin V-FITC/PI double staining and the mitochondrial membrane potential was detected by JC-1 fluorescence dye combined with flow cytometry. The potential mechanisms for protein levels of apoptosis and autophagy were evaluated by western blot. Treatment of HL-60 cells with SPD resulted in growth inhibition (IC 50 value of 2.0 ± 0.2 µM, after 48 h treatment) and induction of apoptosis and autophagy. Results from Annexin V-FITC/PI double-staining assay and mitochondrial membrane potential detection showed that apoptosis was happened after SPD treatment. The regulation of caspase-3, Bax, Bcl-2, PARP following SPD treatment contributed to the induction of mitochondria-dependent apoptosis. Meanwhile, SPD induced autophagy related with Akt/mTOR/p70S6K signaling and activated of AMPK signaling pathway. Furthermore, blocking autophagy with bafilomycin A1 reduced the cytotoxicity of SPD in HL-60 cells. The antiproliferative, apoptosis and pro

    Full Text Available Flour dusts are one of the most harmful chemicals in the bakery industries which could lead to serious heart and lung diseases. This study investigated the effect of flour dust on Peak Expiratory Flow Rate of male bakers in Abeokuta, Ogun State, Nigeria with the relationship to the anthropometrical parameters. A total of One hundred Eighty (180 male participants were investigated, where ninety (90 participants were bakers and ninety (90 individuals as control group. The Peak expiratory flow rate (PEFR and anthropometrical parameters of the participant were measured using mini-Wright peak flow meter (PFM 20, OMRON and Detecto PD300MDHR (Cardinal Scale manufacturing company, USA column scale with digital height rod was used to measure body mass [kg] and height (cm respectively. The PEFR and anthropometrical parameters of the bakers and control groups were analysed using descriptive statistics and T-test with SPSS. The results showed that lower PEFR, 182.67 ± 16.34 L/min existed in bakers compared to 287.67 ± 17.02 L/min in the control study. The result also showed that a significant correlation exist between body mass, height and age (P < 0.01, PEFR, height (P < 0.05 and years of exposure (P < 0.01 of the bakers respectively. Furthermore, the results also showed that workers in the dusting and mixing of flour are at a risk of developing related pulmonary function impairment such as asthma. The study concluded that there is need to develop an effective intervention strategy, treatment seeking behaviour through awareness programs to prevent lung impairment diseases among the bakery workers.

    During bread-making processes, yeast cells are exposed to baking-associated stresses such as freeze-thaw, air-drying, and high-sucrose concentrations. Previously, we reported that self-cloning diploid baker's yeast strains that accumulate proline retained higher-level fermentation abilities in both frozen and sweet doughs than the wild-type strain. Although self-cloning yeasts do not have to be treated as genetically modified yeasts, the conventional methods for breeding baker's yeasts are more acceptable to consumers than the use of self-cloning yeasts. In this study, we isolated mutants resistant to the proline analogue azetidine-2-carboxylate (AZC) derived from diploid baker's yeast of Saccharomyces cerevisiae. Some of the mutants accumulated a greater amount of intracellular proline, and among them, 5 mutants showed higher cell viability than that observed in the parent wild-type strain under freezing or high-sucrose stress conditions. Two of them carried novel mutations in the PRO1 gene encoding the Pro247Ser or Glu415Lys variant of γ-glutamyl kinase (GK), which is a key enzyme in proline biosynthesis in S. cerevisiae. Interestingly, we found that these mutations resulted in AZC resistance of yeast cells and desensitization to proline feedback inhibition of GK, leading to intracellular proline accumulation. Moreover, baker's yeast cells expressing the PRO1 P247S and PRO1 E415K gene were more tolerant to freezing stress than cells expressing the wild-type PRO1 gene. The approach described here could be a practical method for the breeding of proline-accumulating baker's yeasts with higher tolerance to baking-associated stresses. Copyright © 2016 Elsevier B.V.

    Based on the biomineralization assembly concept, a simple and inexpensive biomimetic sol-gel method is found to synthesize high-performance mesoporous LiFePO(4) (HPM-LFP). The key step of this approach is to apply Baker's yeast cells as both a structural template and a biocarbon source. The formation mechanism of ordered hierarchical mesoporous network structure is revealed by characterizing its morphology and microstructure. The HPM-LFP exhibits outstanding electrochemical performances. The HPM-LFP has a high discharge capacity (about 153 mAh g(-1) at a 0.1 C rate), only 2% capacity loss from the initial value after 100 cycles at a current density of 0.1 C. This simple and potentially universal design strategy is currently being pursued in the synthesis of an ideal cathode-active material for high power applications. Copyright © 2012 Elsevier B.V.

    Bienwald, B.; Heitmann, P.

    1978-01-01

    The interaction of uranyl ions with inorganic pyrophosphatase from baker's yeast was investigated by measurement of their effect on the protein fluorescence. Fluorescence titrations of the native enzyme with uranyl nitrate show that there is a specific binding of uranyl ions to the enzyme. It was deduced that each subunit of the enzyme binds one uranyl ion. The binding constant was estimated to be in the order of 10 7 M -1 . The enzyme which contains a small number of chemically modified carboxyl groups was not able to bind uranyl ions specifically. The modification of carboxyl groups was carried out by use of a water soluble carbodiimide and the nucleophilic reagent N-(2,4-dinitro-phenyl)-hexamethylenediamine. The substrate analogue calcium pyrophosphate displaced the uranyl ions from their binding sites at the enzyme From the results it is concluded that carboxyl groups of the active site are the ligands for the binding of uranyl ions.

    Full Text Available This paper discusses Gordon Baker’s interpretation of the later Wittgenstein, in particular his interpretation of the notion of Wittgensteinian philosophical conceptions (Auffassungen and the notions of non-exclusivity, local incompatibility, non-additivity and global pluralism which Baker uses to characterize Wittgensteinian conceptions. On the basis of this discussion, and a critique of certain features of Baker’s interpretation of Wittgensteinian conceptions, I introduce the notion of a multidimensional logical description of language use, explaining how this notion, which Baker’s interpretation excludes, constitutes and important element of the later Wittgenstein’s philosophical method of clarification and perspicuous representation. I conclude by explaining how Baker’s problematic notions of local incompatibility and non-additivity, if they are seen in the light of Wittgenstein’s criticisms of certain views of the completeness of philosophical or logical accounts, nevertheless point in the right direction.

    Full Text Available Abstract Background The diagnosis of deep vein thrombosis of leg is very common in clinical practice. Not infrequently a range of pathologies are diagnosed after excluding a thrombosis, often after a period of anticoagulation. Case presentation This is a report of three patients who presented with a painful swollen leg and were initially treated as a deep vein thrombosis or a baker's cyst, but later diagnosed as a pleomorphic sarcoma, a malignant giant cell tumor of the muscle and a myxoid liposarcoma. A brief review of such similar reports and the relevant literature is presented. Conclusion A painful swollen leg is a common clinical scenario and though rare, tumors must be thought of without any delay, in a duplex negative, low risk deep vein thrombosis situation.

    The study was aimed at investigating the best biotransformation conditions to increase intracellular glutathione (GSH) levels in samples of baker's yeast (Saccharomyces cerevisiae) employing either the commercially available compressed and dried forms. Glucose, GSH precursors amino acids, as well as other cofactors, were dissolved in a biotransformation solution and yeast cells were added (5%dcw). Two response surface central composite designs (RSCCDs) were performed in sequence: in the first step the influence of amino acid composition (cysteine, glycine, glutamic acid and serine) on GSH accumulation was investigated; once their formulation was set up, the influence of other components was studied. Initial GSH content was found 0.53 and 0.47%dcw for compressed and dried forms. GSH accumulation ability of baker's yeast in compressed form was higher at the beginning of shelf life, that is, in the first week, and a maximum of 2.04%dcw was obtained. Performance of yeast in dried form was not found satisfactory, as the maximum GSH level was 1.18%dcw. When cysteine lacks from the reaction solution, yeast cells do not accumulate GSH. With dried yeast, the highest GSH yields occurred when cysteine was set at 3 g/L, glycine and glutamic acid at least at 4 g/L, without serine. Employing compressed yeast, the highest GSH yields occurred when cysteine and glutamic acid were set at 2-3 g/L, while glycine and serine higher than 2 g/L. Results allowed to set up an optimal and feasible procedure to obtain GSH-enriched yeast biomass, with up to threefold increase with respect to initial content. Copyright © 2012 Elsevier B.V.

    Proterozoic sequences associated with major unconformities are potential uranium metallogenic provinces. Late Aphebian to Paleohelikian Dubawnt Group contintental clastic sedimentary and subaerial alkaline volcanic rocks and underlying Archean gneisses, District of Keewatin, Northwest Territories, represent one such uraniferous metallogenic province. Three types of uranium mineralization are present in the eastern Baker Lake basin, which extends from Christopher Island at the eastern end of Baker Lake southwestwards to the western limit of Thirty Mile Lake. The three uranium associations are: 1) fracture controlled mineralization in the Dubawnt Group and basement gneisses (U-Cu-Ag-Au-Se or U-Cu-Pb-Mo-Zn), 2)diatreme breccia mineralization in basement gneisses (U-Cu-Zn), and 3) impregnation and microfracture mineralization in altered arkose peripheral to lamprophyre dykes(U-Cu-Ag). Hydrothermal fracture related mineralization is controlled by northwest- and east-northeast-trending fault-fracture zones. Diatreme breccia mineralization results from the channelling of groundwaters through highly permeable brecciated gneiss. Mineralization within the altered Kazan arkose peripheral to alkaline dyke complexes formed by a two stage process. Iron and copper sulphides and silver were deposited within the outer portions of the thermal aureole in response to a temperature and Eh gradient across a convective cell created by the thermal anomaly of the dyke complex. The epigenetic sulphide mineralization subsequently provided the reducing environment for precipitation of uranium from groundwater. All three uranium associations show a close spatial distribution to the basal Dubawnt unconformity. The lithological and structural relationships of the Dubawnt Group rocks, types of mineralization and associated alteration assemblages are strikingly similar to the Beaverlodge district, Saskatchewan.

  16. The lost castle of Count Rodrigo Gonzalez

    Ehrlich, Michael

    2015-12-01

    Full Text Available This article suggests that a castle called Toron built in 1137 by Count Rodrigo of Lara, and granted to the Templar Order was in Summil, where remains of a Crusader castles are still visible (ca. 25 km from Ascalon, in south west Israel. This opinion opposes a consensual view that the castle built by Count Rodrigo was in Latrun, midway between Tel-Aviv and Jerusalem. This identifi cation is based on names’ similarity and on the universal opinion that Latrun was a Templar castle. In this article it is demonstrated that the geographic setting of Summil fi ts the Count’s castle, whereas Latrun does not; that Toron was a common name in the Crusader Kingdom; and, moreover, it is not certain that Latrun was a Templar castle. The article also suggest that there was a village near the castle, called Casale Sancti Salvatoris, and also discusses Frankish fortifi cation and settlement policy during the twelfth century.Este artículo sugiere que un castillo llamado Toron, construido el año 1137 por el conde Rodrigo González de Lara, y que fue luego otorgado a la orden del Temple, estaba en Summil, donde todavía permanecen las ruinas de un castillo de los cruzados (a unos 25 km de Ascalon, en el sudoeste de Israel. Esta opinión se contrapone a la tesis general que sostiene que el castillo construido por el conde estuvo situado en Latrun, a medio camino entre Tel-Aviv y Jerusalén. Una identificación basada en la similitud de nombres y en la común opinión que Latrun era un castillo templario. En este estudio se demuestra que la ubicación geográfica de Summil encaja con la del castillo del conde, mientras que Latrun no lo hace; que Toron fue un nombre habitual en el reino cruzado y que, por otra parte, no es cierto que Latrun fuera un castillo templario. Se sugiere también que cerca del castillo de Summil existía un pueblo llamado casale Sancti Salvatoris, analizándose asimismo la política de fortificación y colonización llevada a cabo por los cruzados durante el siglo XII.

    Baker's asthma is a serious airway disease triggered by wheat protein CM3 α-amylase/trypsin inhibitor. The purpose of the present study was to investigate the impact of genotype and crop year on allergen CM3 α-amylase/trypsin inhibitor associated with baker's asthma. A historical series of Tunisian durum wheat (100 accessions), derived from three crop years, was used to compare the amount of CM3 from landraces to advanced cultivars. CM3 protein quantification was assessed after an enzymatic cleavage of the soluble protein extracts on a UPLC/ESI-MS system, using a marker peptide for its quantification. Combined data analysis of variance revealed an important effect of genotype, crop year, and their interaction. The CM3 allergenic proteins were found to significantly vary among studied genotypes, as confirmed by genetic variability, coefficient of variance, heritability, and genetic advance.

    Allergic IgE-mediated reactions to neuromuscular blocking agents (NMBAs) are the main cause of immediate hypersensitivity reactions in anaesthesia; their predominant occurrence in the absence of previous exposure to NMBAs suggests a risk related to environmental exposure. To investigate the prevalence of specific IgE to quaternary ammonium ions in two populations professionally exposed to quaternary ammonium compounds, in the north-eastern France. The study had a retrospective follow-up design whereby apprentices were assessed after their 2-year training period as apprentices. The professionally exposed hairdresser populations (n = 128) were compared with baker/pastry makers (n = 108) and 'non-exposed' matched control subjects (n = 379). We observed a 4.6-fold higher frequency of positive IgE against quaternary ammonium ions in hairdressers (HD), compared with baker/pastry makers (BP) and control (C) groups. The competitive inhibition of quaternary ammonium Sepharose radioimmunoassay (QAS-IgE RIA) with succinylcholine was significantly higher in HD, compared with BP and C groups, with inhibition percentage of 66.2 ± 7.4, 39.7 ± 6.0 and 43.8 ± 9.9, respectively (P  100 kU/L were the two significant predictors of IgE-sensitization against quaternary ammonium ions in the multivariate analysis of a model that included age, sex, professional exposure, increased concentration of total IgE (IgE > 100 kU/L) and positive IgE against prevalent allergens (Phadiatop(®) ; P = 0.019 and P = 0.001, respectively). The exposure to hairdressing professional occupational factors increases IgE-sensitization to NMBAs and quaternary ammonium ion compounds used in hairdressing. Besides the pholcodine hypothesis, our study suggests that repetitive exposure to quaternary ammonium compounds used in hairdressing is a risk factor for NMBAs sensitization. © 2013 John Wiley & Sons Ltd.

    The area immediately east of Baker Creek, Blaine County, Idaho, is underlain by a thick section of mafic to intermediate lava flows of the Eocene Challis Volcanic Group. Widespread propylitic alteration surrounds a zone of argillic alteration and an inner core of phyllic alteration. Silicified breccia is present along an east-trending fault within the zone of phyllic alteration. As part of a reconnaissance geochemical survey, soils and plants were sampled. Several species of plants (Douglas-fir [ Pseudotsuga menziesii ], mountain big sagebrush [ Artemisia tridentata ssp. vaseyana ], and elk sedge [ Carex geyerii ]) were collected from 10 upland localities and stream sediments, panned concentrates, and aquatic mosses were collected from 16 drainage basin localities all of which were generally within the area of alteration. Geochemical results yielded anomalous concentrations of molybenum, zinc, silver, and lead in at least half of the seven different sample media and of gold, thallium, arsenic, antimony, manganese, boron, cadmium, bismuth, copper, and beryllium in from one to four of the various media. Part of this suite of elements? silver, gold, arsenic, antimony, thallium, and manganese? suggests that the mineralization in the area is epithermal. Barite and pyrite (commonly botryoidal-framboidal) are widespread throughout the area sampled. Visible gold and pyromorphite (a secondary lead mineral) were identified in only one small drainage basin, but high levels of gold were detected in aquatic mosses over a larger area. Data from the upland and stream sampling indicate two possible mineralized areas. The first mineralized area was identified by a grab sample from an outcrop of quartz stockwork that contained 50 ppb Au, 1.5 ppm Ag, and 50 ppm Mo. Although the soil and plant species that were sampled in the area indicated mineralized bedrock, the Douglas-fir samples were the best indicators of the silver anomaly. The second possible mineralized area centers on the

  2. Simplifying the Reinsch algorithm for the Baker-Campbell-Hausdorff series

    The Goldberg version of the Baker-Campbell-Hausdorff series computes the quantity Z ( X , Y ) = ln (" separators=" e X e Y ) = ∑ w g ( w ) w ( X , Y ) , where X and Y are not necessarily commuting in terms of "words" constructed from the {X, Y} "alphabet." The so-called Goldberg coefficients g(w) are the central topic of this article. This Baker-Campbell-Hausdorff series is a general purpose tool of very wide applicability in mathematical physics, quantum physics, and many other fields. The Reinsch algorithm for the truncated series permits one to calculate the Goldberg coefficients up to some fixed word length |w| by using nilpotent (|w| + 1) × (|w| + 1) matrices. We shall show how to further simplify the Reinsch algorithm, making its implementation (in principle) utterly straightforward using "off the shelf" symbolic manipulation software. Specific computations provide examples which help to provide a deeper understanding of the Goldberg coefficients and their properties. For instance, we shall establish some strict bounds (and some equalities) on the number of non-zero Goldberg coefficients. Unfortunately, we shall see that the number of nonzero Goldberg coefficients often grows very rapidly (in fact exponentially) with the word length |w|. Furthermore, the simplified Reinsch algorithm readily generalizes to many closely related but still quite distinct problems—we shall also present closely related results for the symmetric product S ( X , Y ) = ln (" separators=" e X / 2 e Y e X / 2 ) = ∑ w g S ( w ) w ( X , Y ) . Variations on such themes are straightforward. For instance, one can just as easily consider the "loop" product L ( X , Y ) = ln (" separators=" e X e Y e - X e - Y ) = ∑ w g L ( w ) w ( X , Y ) . This "loop" type of series is of interest, for instance, when considering either differential geometric parallel transport around a closed curve, non-Abelian versions of Stokes' theorem, or even Wigner rotation/Thomas precession in special

    During the bread-making process, industrial baker's yeast cells are exposed to multiple baking-associated stresses, such as elevated high-temperature, high-sucrose and freeze-thaw stresses. There is a high demand for baker's yeast strains that could withstand these stresses with high leavening ability. The SNR84 gene encodes H/ACA snoRNA (small nucleolar RNA), which is known to be involved in pseudouridylation of the large subunit rRNA. However, the function of the SNR84 gene in baker's yeast coping with baking-associated stresses remains unclear. In this study, we explored the effect of SNR84 overexpression on baker's yeast which was exposed to high-temperature, high-sucrose and freeze-thaw stresses. These results suggest that overexpression of the SNR84 gene conferred tolerance of baker's yeast cells to high-temperature, high-sucrose and freeze-thaw stresses and enhanced their leavening ability in high-sucrose and freeze-thaw dough. These findings could provide a valuable insight for breeding of novel stress-resistant baker's yeast strains that are useful for baking. Copyright © 2015 Elsevier B.V. All rights reserved.

    Vanillin is one of the world's most important flavor compounds, with a global market of 180 million dollars. Natural vanillin is derived from the cured seed pods of the vanilla orchid (Vanilla planifolia), but most of the world's vanillin is synthesized from petrochemicals or wood pulp lignins. We have established a true de novo biosynthetic pathway for vanillin production from glucose in Schizosaccharomyces pombe, also known as fission yeast or African beer yeast, as well as in baker's yeast, Saccharomyces cerevisiae. Productivities were 65 and 45 mg/liter, after introduction of three and four heterologous genes, respectively. The engineered pathways involve incorporation of 3-dehydroshikimate dehydratase from the dung mold Podospora pauciseta, an aromatic carboxylic acid reductase (ACAR) from a bacterium of the Nocardia genus, and an O-methyltransferase from Homo sapiens. In S. cerevisiae, the ACAR enzyme required activation by phosphopantetheinylation, and this was achieved by coexpression of a Corynebacterium glutamicum phosphopantetheinyl transferase. Prevention of reduction of vanillin to vanillyl alcohol was achieved by knockout of the host alcohol dehydrogenase ADH6. In S. pombe, the biosynthesis was further improved by introduction of an Arabidopsis thaliana family 1 UDP-glycosyltransferase, converting vanillin into vanillin beta-D-glucoside, which is not toxic to the yeast cells and thus may be accumulated in larger amounts. These de novo pathways represent the first examples of one-cell microbial generation of these valuable compounds from glucose. S. pombe yeast has not previously been metabolically engineered to produce any valuable, industrially scalable, white biotech commodity.

    γ-Aminobutyric acid (GABA) is consumed by yeasts during fermentation. To prevent GABA reduction in bread dough, a baker's yeast mutant AY77 deficient in GABA assimilation was characterized and utilized for wheat dough fermentation. An amber mutation in the DAL81 gene, which codes for a positive regulator of multiple nitrogen degradation pathways, was found in the AY77 strain. The qPCR analyses of genes involved in nitrogen utilization showed that transcriptional levels of the UGA1 and DUR3 genes encoding GABA transaminase and urea transporter, respectively, are severely decreased in the AY77 cells. The AY77 strain cultivated by fed-batch culture using cane molasses exhibited inferior gas production during dough fermentation compared to that of wild-type strain AY13. However, when fed with molasses containing 0.5% ammonium sulfate, the mutant strain exhibited gas production comparable to that of the AY13 strain. In contrast to the AY13 strain, which completely consumed GABA in dough within 5 h, the AY77 strain consumed no GABA under either culture condition. Dough fermentation with the dal81 mutant strain should be useful for suppression of GABA reduction in breads. Copyright © 2016 The Society for Biotechnology, Japan. Published by Elsevier B.V.

    Full Text Available Elettariopsis curtisii Baker, the culinary and medicinal herb, was investigated to elucidate its chemical constituents and determine antioxidant and antibacterial activities. The essential oil of E. curtisii was obtained by steam distillation of fresh rhizomes in a maximum yield of 0.63%. GC-MS data indicated the presence of six compounds, of which trans-2-decenal (78.03% was the principal constituent. The essential oils and also the hexane, dichloromethane and methanol extracts from the rhizomes and leaves were assessed for antioxidant and antibacterial activities. In an evaluation of antioxidant activity, the crude dichloromethane extract of the leaves exhibited the highest scavenging effect on the DPPH radicalwith an EC50 of 0.28+0.01 mg/mL. The leaf dichloromethane extract also had the highest total phenol concentration, (73.4+2.80 mg GA/g of extract whereas the crude methanol extract from the rhizomes had the highest reducing power with an EC50 of 2.07+0.06 mg/mL. In terms of antibacterial activity, the essential oil (distilled from either the leaves or the rhizomesdisplayed the highest inhibitory activity, with the same MID value of 1 mg/disc against 5 strains of bacteria, Bacillus subtilis,Escherichia coli, Staphylococcus aureus, Sarcina sp. and Pseudomonas aeruginosa.

    In the laboratory-scale experiments, treatment of baker's yeast production wastewater has been investigated by electrocoagulation (EC) using a batch reactor. Effects of the process variables such as pH, electrode material (Fe and Al), current density, and operating time are investigated in terms of removal efficiencies of chemical oxygen demand (COD), total organic carbon (TOC), turbidity, and operating cost, respectively. The maximum removal efficiencies of COD, TOC and turbidity under optimal operating conditions, i.e., pH 6.5 for Al electrode and pH 7 for Fe electrode, current density of 70 A/m{sup 2} and operating time of 50 min were 71, 53 and 90% for Al electrode and 69, 52 and 56% for Fe electrode, respectively. Al electrode gave 4.4 times higher removal efficiency of turbidity than Fe electrode due to interference from color of dissolved iron. The operating costs for Al and Fe electrodes in terms of $/m{sup 3} or $/kg COD were 1.54 and 0.82, 0.51 and 0.27, respectively.

    Full Text Available Probabilistic functional gene networks are powerful theoretical frameworks for integrating heterogeneous functional genomics and proteomics data into objective models of cellular systems. Such networks provide syntheses of millions of discrete experimental observations, spanning DNA microarray experiments, physical protein interactions, genetic interactions, and comparative genomics; the resulting networks can then be easily applied to generate testable hypotheses regarding specific gene functions and associations.We report a significantly improved version (v. 2 of a probabilistic functional gene network of the baker's yeast, Saccharomyces cerevisiae. We describe our optimization methods and illustrate their effects in three major areas: the reduction of functional bias in network training reference sets, the application of a probabilistic model for calculating confidences in pair-wise protein physical or genetic interactions, and the introduction of simple thresholds that eliminate many false positive mRNA co-expression relationships. Using the network, we predict and experimentally verify the function of the yeast RNA binding protein Puf6 in 60S ribosomal subunit biogenesis.YeastNet v. 2, constructed using these optimizations together with additional data, shows significant reduction in bias and improvements in precision and recall, in total covering 102,803 linkages among 5,483 yeast proteins (95% of the validated proteome.

    Thermodynamic concepts have been used in the past to predict microbial growth yield. This may be the key consideration in many industrial biotechnology applications. It is not the case, however, in the context of ethanol fuel production. In this paper, we examine the thermodynamics of fermentation and concomitant growth of baker's yeast in continuous culture experiments under anaerobic, glucose-limited conditions, with emphasis on the yield and efficiency of bio-ethanol production. We find that anaerobic metabolism of yeast is very efficient; the process retains more than 90% of the maximum work that could be extracted from the growth medium supplied to the chemostat reactor. Yeast cells and other metabolic by-products are also formed, which reduces the glucose-to-ethanol conversion efficiency to less than 75%. Varying the specific ATP consumption rate, which is the fundamental parameter in this paper for modeling the energy demands of cell growth, shows the usual trade-off between ethanol production and biomass yield. The minimum ATP consumption rate required for synthesizing cell materials leads to biomass yield and Gibbs energy dissipation limits that are much more severe than those imposed by mass balance and thermodynamic equilibrium constraints. 2010 Elsevier B.V.

    The highly osmo- and cryotolerant yeast species Torulaspora delbrueckii is an important case study among the non-Saccharomyces yeast species. The strain T. delbrueckii PYCC 5321, isolated from traditional corn and rye bread dough in northern Portugal, is considered particularly interesting for the baking industry. This paper reports the sugar utilization patterns of this strain, using media with glucose, maltose and sucrose, alone or in mixtures. Kinetics of growth, biomass and ethanol yields, fermentation and respiration rates, hydrolase activities and sugar uptake rates were used to infer the potential applied relevance of this yeast in comparison to a conventional baker's strain of Saccharomyces cerevisiae. The results showed that both maltase and maltose transport in T. delbrueckii were subject to glucose repression and maltose induction, whereas invertase was subject to glucose control but not dependent on sucrose induction. A comparative analysis of specific sugar consumption rates and transport capacities suggests that the transport step limits both glucose and maltose metabolism. Specific rates of CO(2) production and O(2) consumption showed a significantly higher contribution of respiration to the overall metabolism in T. delbrueckii than in S. cerevisiae. This was reflected in the biomass yields from batch cultures and could represent an asset for the large-scale production of the former species. This work contributes to a better understanding of the physiology of a non-conventional yeast species, with a view to the full exploitation of T. delbrueckii by the baking industry.

  11. Fidelity, Adaptation, and Meta-commentary: The Case of Susan Orlean’s The Orchid Thief and Spike Jonze’s Adaptation

    Directory of Open Access Journals (Sweden)

    Victoria de Zwaan

    2017-12-01

    Full Text Available Abstract Susan Orlean’s The Orchid Thief has raised and defied questions about genre since its appearance in 1998. Though “research” and “facts” are at the foreground of the book, critics have described it by such terms as literary non-fiction, faction, personal journalism, and non-fiction novel because of its strong “literary,” that is narrative, characterological, thematic, and even philosophical, qualities. Struggling to make a faithful adaptation of this “simple” and “beautiful” book “about flowers” for film, Charlie Kaufman, the neurotic and anxious protagonist/screenwriter of Adaptation (2002, a fictionalized avatar of the real-life Charlie Kaufman, works through the wide range of possible generic and narrative adaptive possibilities that the book invites. The series of apparent false starts eventually get resolved, in a desperate attempt at creating closure, by way of the “Hollywood ending” that the screenwriter ostensibly despises and insists he will avoid. This paper engages the complex relationships between these two objects – The Orchid Thief and Adaptation – first, by providing some interpretive analysis of Orlean’s book and its potential adaptive possibilities, and second, by examining what happens to those possibilities in Adaptation. On my argument, the film refracts the book’s concerns into a meditation on the processes of reading, storytelling, and interpretation in the realm of explicit adaptation by way of metafiction, metalepsis, and other techniques associated with experimental narrative.

    Full Text Available Abstract Background The natural history of occupational asthma (OA is influenced by many determinants. This study aims to assess the combined roles of personal characteristics, including occupational exposure and nutritional habits, on the incidence of OA during the first years at work. Methods A nested case–control study was conducted within a retrospective cohort of young workers in the bakery, pastry-making and hairdressing sectors. Cases were subjects diagnosed as ‘confirmed’ or ‘probable’ OA consecutively to a medical visit (N = 31. Controls were subjects without OA (N = 196. Atopy was defined after blood specific IgE analysis, based on the PhadiatopTM test. Occupational exposure was characterized by standardized questionnaires and diet patterns by a food frequency questionnaire. Results Among bakers and pastry-makers, only atopy is an independent risk factor of OA (OR = 10.07 95%CI [2.76 – 36.65]. Among hairdressers, several variables are associated with OA. Body mass index (unit OR = 1.24 [1.03 – 1.48] and the score of exposure intensity (unit OR = 1.79 [1.05 – 3.05] are independent predictors of OA, but the role of atopy is weak (OR = 4.94 [0.66 – 36.75]. Intake of vitamin A is higher among hairdressers cases (crude p = 0.002, adjusted p = 0.01 after control for body mass index and atopy; the same observation is made for vitamin D (crude p = 0.004, adjusted p = 0.01. Conclusion This study suggests that the influence of several factors on the incidence of OA, including dietary vitamins, might vary across exposure settings.

  14. Intermolecular hydrogen transfer catalyzed by a flavodehydrogenase, bakers' yeast flavocytochrome b2

    Urban, P.; Lederer, F.

    1985-01-01

    Bakers yeast flavocytochrome b2 is a flavin-dependent L-2-hydroxy acid dehydrogenase which also exhibits transhydrogenase activity. When a reaction takes place between [2- 3 H]lactate and a halogenopyruvate, tritium is found in water and at the halogenolactate C2 position. When the halogenopyruvate undergoes halide ion elimination, tritium is also found at the C3 position of the resulting pyruvate. The amount tau of this intermolecular tritium transfer depends on the initial keto acid-acceptor concentration. At infinite acceptor concentration, extrapolation yields a maximal transfer of 97 +/- 11%. This indicates that the hydroxy acid-derived hydrogen resides transiently on enzyme monoprotic heteroatoms and that exchange with bulk solvent occurs only at the level of free reduced enzyme. Using a minimal kinetic scheme, the rate constant for hydrogen exchange between Ered and solvent is calculated to be on the order of 10(2) M-1 S-1, which leads to an estimated pK approximately equal to 15 for the ionization of the substrate-derived proton while on the enzyme. It is suggested that this hydrogen could be shared between the active site base and Flred N5 anion. It is furthermore shown that some tritium is incorporated into the products when the transhydrogenation is carried out in tritiated water. Finally, with [2-2H]lactate-reduced enzyme, a deuterium isotope effect is observed on the rate of bromopyruvate disappearance. Extrapolation to infinite bromopyruvate concentration yields DV = 4.4. An apparent inverse isotope effect is determined for bromide ion elimination. These results strengthen the idea that oxidoreduction and elimination pathways involve a common carbanionic intermediate

    2013-12-01

    Global climate models (GCMs) forced by increased CO2 emissions forecast anomalously dry and warm trends over the southwestern U.S. for the 21st century. The effect of warmer conditions may result in decreased surface water resources within the Great Basin physiographic region critical for ecology, irrigation and municipal water supply. Here we use downscaled GCM output from the A2 and B1 greenhouse gas emission scenarios to force a Precipitation-Runoff Modeling System (PRMS) watershed model developed for the Lehman and Baker Creeks Drainage (LBCD) in the Great Basin National Park, NV for a century long time period. The goal is to quantify the effects of rising temperature to the water budget in the LBCD at monthly and annual timescales. Dynamically downscaled GCM projections are attained from the NSF EPSCoR Nevada Infrastructure for Climate Change Science, Education, and Outreach project and statistically downscaled output is retrieved from the "U.S. Bias Corrected and Downscaled WCRP CMIP3 Climate Projections". Historical daily climate and streamflow data have been collected simultaneously for periods extending 20 years or longer. Mann-Kendal trend test results showed a statistically significant (α= 0.05) long-term rising trend from 1895 to 2012 in annual and monthly average temperatures for the study area. A grid-based, PRMS watershed model of the LBCD has been created within ArcGIS 10, and physical parameters have been estimated at a spatial resolution of 100m. Simulation results will be available soon. Snow cover is expected to decrease and peak runoff to occur earlier in the spring, resulting in increased runoff, decreased infiltration/recharge, decreased baseflows, and decreased evapo-transpiration.

The engineered pathways involve incorporation of 3-dehydroshikimate dehydratase from the dung mold Podospora pauciseta, an aromatic carboxylic acid reductase (ACAR) from a bacterium of the Nocardia genus, and an O-methyltransferase from Homo sapiens. In S. cerevisiae, the ACAR enzyme required activation by phosphopantetheinylation, and this was achieved by coexpression of a Corynebacterium glutamicum phosphopantetheinyl transferase. Prevention of reduction of vanillin to vanillyl alcohol was achieved by knockout of the host alcohol dehydrogenase ADH6. In S. pombe, the biosynthesis was further improved by introduction of an Arabidopsis thaliana family 1 UDP-glycosyltransferase, converting vanillin into vanillin β-d-glucoside, which is not toxic to the yeast cells and thus may be accumulated in larger amounts. These de novo pathways represent the first examples of one-cell microbial generation of these valuable compounds from glucose. S. pombe yeast has not previously been metabolically engineered to produce any valuable, industrially scalable, white biotech commodity. PMID:19286778

    Full Text Available Baker's yeast is a set of living cells of Saccharomyces cerevisiae. It contains around 70-72% of water, 42-45% of proteins, around 40% of carbohydrates, around 7.5% of lipids (based on dry matter, and vitamin B-complex. On the basis of yeast cell analysis it can be concluded that yeast is a complex biological system which changes in time. The intensity of the changes depends on temperature. Yeast sample was stored at 4°C i 24°C for 12 days. During storage at 4°C, the content of total carbohydrates decreased from 48.81% to 37.50% (dry matter, whereas carbohydrate loss ranged from 40.81% to 29.28% at 24°C. The content of trehalose was 12.33% in the yeast sample stored at 4°C and 0.24% at 24°C. Loss of fermentative activity was 81.76% in the sample stored at 24°C for 12 days. The composition of five samples of 1st category flour was investigated. It was found that flours containing more reducing sugars and maltose enable higher fermentation activities. The flours with higher ash content (in the range 0.5-0.94% had higher contents of phytic acid. Higher ash and phytic contents in flour increased the yeast fermentative efficiency. In bakery industry, a range of ingredients has been applied to improve the product's quality such as surface active substances (emulsifiers, enzymes, sugars and fats. In the paper, the effect of some ingredients added to dough (margarine, saccharose, sodium chloride and malted barley on the yeast fermentative activity was studied. The mentioned ingredients were added to dough at different doses: 0.5, 1.0, 1.5 and 2.0%, flour basis. It was found that the investigated ingredients affected the fermentative activity of yeast and improved the bread quality.

    The present study was carried out to explore baker's yeasts strains from sugarcane juice to assess its potential in laboratory scale production of breads. Collected juice samples were processed for isolation and identification of yeast strains based on standard cultural, morphological and biochemical characteristics. Among the six isolated strains, four (designated as S1, S2, S5 and S6) were identified as Saccharomyces cerevisiae and the rests (designated S3 and S4) were as S. rouxii. When assessing their CO2 production rates as a measure of their baking potential, S6 was found to produce maximum amount of gas (226.67 mm3 mL(-1)) in sucrose broth, whereas gas produced by S2, S1 and S5 were relatively insignificant (170, 136.67 and 86.67 mm3 mL(-1), respectively). No strain was found to produce undesirable H2S gas responsible for off-flavor. Besides, effects of different physicochemical parameters (e.g., pH, temperature, substrate concentration, incubation period, agitation etc.) on the production of yeast cell-mass were studied. Yield of cell mass was indirectly measured by spectrophotometric method at 550 nm. All the test isolates were found to produce maximum cell mass at a pH range of 4.0 to 5.0 in 2 to 4% molasses broth at 30 degrees C after 4 days of incubation. In the laboratory scale production of bread using composite flour, Isolate-S6 formed significant characteristic texture. Considering overall characteristics, Isolate- S6 was found to be satisfactorily potent for baking purpose.

  20. When is Deceptive Message Production More Effortful than Truth-Telling? A Baker's Dozen of Moderators.

    Deception is thought to be more effortful than telling the truth. Empirical evidence from many quarters supports this general proposition. However, there are many factors that qualify and even reverse this pattern. Guided by a communication perspective, I present a baker's dozen of moderators that may alter the degree of cognitive difficulty associated with producing deceptive messages. Among sender-related factors are memory processes, motivation, incentives, and consequences. Lying increases activation of a network of brain regions related to executive memory, suppression of unwanted behaviors, and task switching that is not observed with truth-telling. High motivation coupled with strong incentives or the risk of adverse consequences also prompts more cognitive exertion-for truth-tellers and deceivers alike-to appear credible, with associated effects on performance and message production effort, depending on the magnitude of effort, communicator skill, and experience. Factors related to message and communication context include discourse genre, type of prevarication, expected response length, communication medium, preparation, and recency of target event/issue. These factors can attenuate the degree of cognitive taxation on senders so that truth-telling and deceiving are similarly effortful. Factors related to the interpersonal relationship among interlocutors include whether sender and receiver are cooperative or adversarial and how well-acquainted they are with one another. A final consideration is whether the unit of analysis is the utterance, turn at talk, episode, entire interaction, or series of interactions. Taking these factors into account should produce a more nuanced answer to the question of when deception is more difficult than truth-telling.

    Full Text Available Abstract Background During the bread-making process, industrial baker's yeast, mostly Saccharomyces cerevisiae, is exposed to baking-associated stresses, such as air-drying and freeze-thaw stress. These baking-associated stresses exert severe injury to yeast cells, mainly due to the generation of reactive oxygen species (ROS, leading to cell death and reduced fermentation ability. Thus, there is a great need for a baker's yeast strain with higher tolerance to baking-associated stresses. Recently, we revealed a novel antioxidative mechanism in a laboratory yeast strain that is involved in stress-induced nitric oxide (NO synthesis from proline via proline oxidase Put1 and N-acetyltransferase Mpr1. We also found that expression of the proline-feedback inhibition-less sensitive mutant γ-glutamyl kinase (Pro1-I150T and the thermostable mutant Mpr1-F65L resulted in an enhanced fermentation ability of baker's yeast in bread dough after freeze-thaw stress and air-drying stress, respectively. However, baker's yeast strains with high fermentation ability under multiple baking-associated stresses have not yet been developed. Results We constructed a self-cloned diploid baker's yeast strain with enhanced proline and NO synthesis by expressing Pro1-I150T and Mpr1-F65L in the presence of functional Put1. The engineered strain increased the intracellular NO level in response to air-drying stress, and the strain was tolerant not only to oxidative stress but also to both air-drying and freeze-thaw stresses probably due to the reduced intracellular ROS level. We also showed that the resultant strain retained higher leavening activity in bread dough after air-drying and freeze-thaw stress than that of the wild-type strain. On the other hand, enhanced stress tolerance and fermentation ability did not occur in the put1-deficient strain. This result suggests that NO is synthesized in baker's yeast from proline in response to oxidative stresses that induce ROS

    During bread-making processes, yeast cells are exposed to multiple stresses. Air-drying stress is one of the most harmful stresses by generation of reactive oxygen species (ROS). Previously, we discovered that the novel N-acetyltransferase Mpr1/2 confers oxidative stress tolerance by reducing intracellular ROS level in Saccharomyces cerevisiae Sigma1278b strain. In this study, we revealed that Japanese industrial baker's yeast possesses one MPR gene. The nucleotide sequence of the MPR gene in industrial baker's yeast was identical to the MPR2 gene in Sigma1278b strain. Gene disruption analysis showed that the MPR2 gene in industrial baker's yeast is involved in air-drying stress tolerance by reducing the intracellular oxidation levels. We also found that expression of the Lys63Arg and Phe65Leu variants with enhanced enzymatic activity and stability, respectively, increased the fermentation ability of bread dough after exposure to air-drying stress compared with the wild-type Mpr1. In addition, our recent study showed that industrial baker's yeast cells accumulating proline exhibited enhanced freeze tolerance in bread dough. Proline accumulation also enhanced the fermentation ability after air-drying stress treatment in industrial baker's yeast. Hence, the antioxidant enzyme Mpr1/2 could be promising for breeding novel yeast strains that are tolerant to air-drying stress. Copyright 2010 Elsevier B.V. All rights reserved.

    Full Text Available The attempts to challenge conventional gendered discourses in children's fantasy have often resulted in feminist rewritings of earlier stories. Ghost dance (1994 by the English author Susan Price is a novel that reflects a specific feminist poetics of rewriting: metafictional passages highlight the constructedness of the narrative and at the end readers are invited to tell their own versions of the story. Moreover, the rewriting freely combines and recontextualises elements from different source texts and reformulates them to create a narrative that challenges conventional discourses of gender. While this poetics has an appeal from a feminist perspective, the play with cross-cultural intertexts and gender becomes more complex when the novel is examined in a postcolonialist framework in relation to ethnicity and the issue of cultural appropriation. Ghost dance is situated in a setting that has a real-world equivalent (Russia, involves characters that are identified with names of real-world ethnic groups (Lapps (Sámi, Russian, and mixes elements from Russian wonder tales, Nordic mythology and an Ojibwe legend. The novel does not aim at historical accuracy in its representations nor is it a direct retelling of any of the pre-texts but combines motifs, themes, names, characters and settings freely from each source. In this textual melting pot, the protagonist Shingebiss is, on one level, a revision of the witch Baba Yaga, but also described as a Lappish shaman with an Ojibwe name. To rewrite gendered discourses, certain elements from the pretexts are chosen and others left out – the question is, then, what effects does this recontextualisation have on the representation of ethnicity? Or, are the feminist rewriting strategies actually a form of cultural appropriation?

    The gamma radiation has been used in several places of the World as a sterilization method, preservation and pasteurization of foodstuffs, effect which is achieved due to diminishing or elimination of the microorganisms, reaching every time more acceptance, moreover eliminates the uses of toxic and carcinogenic substances, of general use, but at the present, being in the process of being totally prohibited, due to the higher risk in the human health. In this work the related results with the effects of the gamma radiation are presented, coming from a 60 Co source, in commercial wheat flour exposed to a dose of 1.0 KGy. The used dose is that allowed according to the NOM-033-SSA1-1993 standard. It was determined that the chemical characteristics of humidity, protein and ashes were not affected by radiation. The rheological properties neither suffer severe effects as consequence of radiation; the pharynographic and alveographic parameters were lightly affected by the treatment. Significant changes were detected in the percentage of water absorption and in the tolerance index to mixing. However a diminish of 10% in the development time and an increase of 13% in the stability was observed, for the irradiated samples respect to the those samples not irradiated. In relation to the alveograph parameters it was only detected a diminish of 7% in the force parameter (w) without changes in the tenacity/blowing up index ratio (P/L). The fall number diminish 11% indicating a small diminution in viscosity. The bakering properties do not turn out modified by the irradiation treatment finding a specific weight of 4.6 and 4.5 (cm 3 /g) for the control and irradiated samples, respectively. In the mesophyll analysis it was found a diminish of 96% from the original charge in control samples, observing a diminution of 74 and 25% in yeasts and mushrooms respectively. Microbiologically it was determined absence of total coliforms bacteria and faecal coliforms in the control samples and of

    During the bread-making process, yeast cells are exposed to many types of baking-associated stress. There is thus a demand within the baking industry for yeast strains with high fermentation abilities under these stress conditions. The POG1 gene, encoding a putative transcription factor involved in cell cycle regulation, is a multicopy suppressor of the yeast Saccharomyces cerevisiae E3 ubiquitin ligase Rsp5 mutant. The pog1 mutant is sensitive to various stresses. Our results suggested that the POG1 gene is involved in stress tolerance in yeast cells. In this study, we showed that overexpression of the POG1 gene in baker's yeast conferred increased fermentation ability in high-sucrose-containing dough, which is used for sweet dough baking. Furthermore, deletion of the POG1 gene drastically increased the fermentation ability in bread dough after freeze-thaw stress, which would be a useful characteristic for frozen dough baking. Thus, the engineering of yeast strains to control the POG1 gene expression level would be a novel method for molecular breeding of baker's yeast. Copyright © 2013 Elsevier B.V. All rights reserved.

    Water-saturated hydrothermal alteration reduces the strength of volcanic edifices, increasing the potential for catastrophic sector collapses that can lead to far traveled and destructive debris flows. Intense hydrothermal alteration significantly lowers the resistivity and magnetization of volcanic rock and therefore hydrothermally altered rocks can be identified with helicopter electromagnetic and magnetic measurements. Geophysical models constrained by rock properties and geologic mapping show that intensely altered rock is restricted to two small (500 m diameter), >150 m thick regions around Sherman Crater and Dorr Fumarole Field at Mount Baker, Washington. This distribution of alteration contrasts with much thicker and widespread alteration encompassing the summits of Mounts Adams and Rainier prior to the 5600 year old Osceola collapse, which is most likely due to extreme erosion and the limited duration of summit magmatism at Mount Baker. In addition, the models suggest that the upper 300 m of rock contains water which could help to lubricate potential debris flows. Slope stability modeling incorporating the geophysically modeled distribution of alteration and water indicates that the most likely and largest ( 0.1 km3) collapses are from the east side of Sherman Crater. Alteration at Dorr Fumarole Field raises the collapse hazard there, but not significantly because of its lower slope angles. Geochemistry and analogs from other volcanoes suggest a model for the edifice hydrothermal system.

    The aim was to study the prevalence of respiratory allergy (rhinitis and asthma) in a population of bakers and pastrycooks. In 1991, 485 bakers and pastry cooks were examined by 27 work-physicians of Loire-Atlantic. The investigation was composed of a standardised questionnaire (signs of respiratory function, atopic history, smoking of tobacco ...), a clinical examination, and tests of respiratory function. An allergy assessment was made of all subjects with symptoms. 14.4% of subjects had rhinitis and 6.4% asthma. Development of these pathologies was clearly job-related for 2/3 of those with rhinitis and more than half of the asthmatics (55%). Occupational rhinitis and asthma were significantly more frequent in bakers than in pastrycooks and were linked to atopic history. Occupational asthma was associated with length of exposure to flour and with occupational rhinitis. In conclusion, these findings are comparable with or a little less than those that have been reported in occupational literature. They under-estimate the importance of the problem because of the occupational selection effect that is associated with these pathologies. Rhinitis and asthma are 1.5 to 3 time more common in bakers than in pastrycooks.

    Full Text Available Introduction: Homoeopathy is a widely used, controversial alternative system of medicine. It is assumed that homoeopathic medicines are slower in action and does not work in acute conditions such as ‘fever’. The study aims to estimate the effectiveness of some homoeopathic remedies in fever and to compare their effects with Paracetamol. Materials and Methods: Baker's yeast fever model of rabbits was used in the study. Rabbits were divided into four different groups (n = 6. Rectal temperature was measured before and after fever induction hourly. After fever induction, medicines were administered orally. Paracetamol and Typhoidinum in 200C and 1M potencies were given orally. ANOVA followed by post hoc test was used for statistical analysis of results. The results were considered statistically significant at P ≤ 0.05. Results: Fever was induced in all the rabbits after 4 h of baker's yeast administration. The results of the study revealed the significant effectiveness of Typhoidinum in 200C and 1M potencies in baker's yeast-induced fever (P = 0.05. Typhoidinum in both potencies showed less significant results as compared to Paracetamol. However, all the medicines’ effects were significant compared to the negative control. Conclusion: Typhoidinum 200C and 1M worked against baker's yeast-induced fever. However, the results were slower and less significant than Paracetamol that might be due to lack of similarity of remedy picture and disease picture.

    In this paper, we evaluate the security of an enhanced double random phase encoding (DRPE) image encryption scheme (2013 J. Lightwave Technol. 31 2533). The original system employs a chaotic Baker map prior to DRPE to provide more protection to the plain image and hence promote the security level of DRPE, as claimed. However, cryptanalysis shows that this scheme is vulnerable to a chosen-plaintext attack, and the ciphertext can be precisely recovered. The corresponding improvement is subsequently reported upon the basic premise that no extra equipment or computational complexity is required. The simulation results and security analyses prove its effectiveness and security. The proposed achievements are suitable for all cryptosystems under permutation and, following that, the DRPE architecture, and we hope that our work can motivate the further research on optical image encryption.

However, cryptanalysis shows that this scheme is vulnerable to a chosen-plaintext attack, and the ciphertext can be precisely recovered. The corresponding improvement is subsequently reported upon the basic premise that no extra equipment or computational complexity is required. The simulation results and security analyses prove its effectiveness and security. The proposed achievements are suitable for all cryptosystems under permutation and, following that, the DRPE architecture, and we hope that our work can motivate the further research on optical image encryption.

    A report is given of a new bread oven, a Baker Perkins Simplex 2000, installed at British Bakeries' Watnall plant under the Energy Efficiency Demonstration Scheme. The energy saving features include 1) a new design of heating system, 2) combustion air pre-heated with burner flue gases, 3) heat recovery from oven chamber to heat hot water and 4) an in-line lidding system. Results are presented for an independent monitoring of both the new oven and one of a conventional design to compare energy consumption and performance. It is shown that the simplex 2000 reduced energy costs at the Watnall plant by Pound 45,900/year. Additional benefits of the new oven include reduced production labour requirements and an increase in productivity of 100% compared with previous models. (UK).

    Full Text Available The aim of this research was to determine the concentrations of calcium, iron, manganese, zinc, potassium and sodium in the water and leaves of Aechmea blanchetiana (Baker L.B species collected between the cities of Ilhéus and Itacaré, Bahia, Brazil and verify if the metals found in the water can be absorbed by the leaves. Flame atomic absorption spectrometry (F AAS and flame photometry were used for the determination of metals. pH measurements, dissolved oxygen and water temperature were also made. The results obtained were used in an exploratory analysis. Principal component analysis (PCA showed clearly the distinct formation of two clusters and the correlation analysis indicated that the leaves of A. blanchetiana seem to absorb iron, calcium, manganese and zinc from the water tank.

    Full Text Available This essay examines the unusual evangelical work of Marilla Baker Ingalls, an American Baptist missionary to Burma from 1851–1902. By the time of her death in Burma at the age of 75, Ingalls was known as one of the most successful Baptist evangelists among Burmese Buddhists. To understand the extraordinary dynamic of Ingalls’ expanding Christian community, this essay focuses on two prominent objects at the Baptist mission: A life-sized dog statue that Ingalls kept chained at the edge of her property and a massive banyan tree covered with biblical illustrations and revered by locals as an abode of divine beings. This essay argues that these objects transformed Ingalls’ American Baptist Christianity into a kind of Burmese religion that revolved around revered objects. Through an examination of the particular shrine practices that pulled people into the Baptist mission, this essay reflects on the larger context of religious encounter, conflict, and representation in modernizing Burma.

    Full Text Available Life cycle of Tenuipalpus heveae Baker (Acari, Tenuipalpidae on leaflets from three rubber tree clones. The biological cycle of Tenuipalpus heveae Baker, 1945 (Tenuipalpidae, a potential rubber tree pest mite, was studied by the observation of individuals reared on leaflets of the clones GT 1, PB 235 and RRIM 600, in controlled environmental conditions. Three daily observations were done of 60 eggs on leaflets from each clone in order to verify the development of immature stages and the female oviposition. The fertility life table was constructed based in the collected data. Mites reared on PB 235 had faster rate of development, requiring less time in days, to double its population in number (TD, and had the highest values for egg production, female longevity, net reproductive rate (Ro, intrinsic rate of natural increase (r m and finite rate of increase (λ. Lower reproductive values and the longest time necessary to reach adult stage were recorded for the mites on GT 1. In all studied clones, the deutonymphal phase had the highest viability, while the larval phase had the lowest, highlighted by the survivorship curve that indicated high mortality during this life stage. The clone PB 235 allowed the most suitable conditions for the development of T. heveae, followed by RRIM 600, while GT 1 was the less suitable substratum to rear this mite species.O ciclo de vida de Tenuipalpus heveae Baker, 1945 (Tenuipalpidae, um potencial ácaro-praga da seringueira, foi estudado a partir de indivíduos criados sobre folíolos destacados dos clones GT 1, PB 235 e RRIM 600, em condições controladas.

    Strenuous exercise, such as running a marathon, is known to suppress mucosal immunity for up to 24 hr, which can increase the risk of developing an upper respiratory tract infection (URTI) and reduced performance capacity (Allgrove JE, Geneen L, Latif S, Gleeson M. Influence of a fed or fasted state on the s-IgA response to prolonged cycling in active men and women.

Baker's yeast beta glucan supplementation increases monocytes and cytokines post-exercise: implications for infection risk? Br J Nutr. 2012;1-9). While many dietary interventions have been used to combat postexercise immune suppression, most have been ineffective. The key purpose of this study was to determine if baker's yeast β-glucan (BG) could positively affect the immune system of individuals undergoing intense exercise stress using two experiments. In the first (E1; N = 182 men and women), BG was compared to placebo supplementation for the incidence of URTI symptoms for 28 days postmarathon. In the second (E2; N = 60 men and women) changes in salivary immunoglobulin A (IgA) were evaluated after 50-min of strenuous cycling when participants had been supplemented for 10 days with either BG (250 mg/day) or placebo (rice flour). For E1, subjects reported URTI symptoms using a daily health log. For E2, saliva was collected prior to, immediately, and 2-hr postexercise using a salivette. Data for E1 and E2 were analyzed using separate analyses of variance (ANOVAs) with repeated measures (p flu symptom days postmarathon compared to placebo (p = .026). In E2, BG was associated with a 32% increase in salivary IgA (p = .048) at 2 hr after exercise compared to placebo. In summary

    Recently it has been introduced an algorithm for the Baker-Campbell-Hausdorff (BCH) formula, which extends the Van-Brunt and Visser recent results, leading to new closed forms of BCH formula. More recently, it has been shown that there are 13 types of such commutator algebras. We show, by providing the explicit solutions, that these include the generators of the semisimple complex Lie algebras. More precisely, for any pair, X, Y of the Cartan-Weyl basis, we find W, linear combination of X, Y, such that exp(X) exp(Y) = exp(W). The derivation of such closed forms follows, in part, by using the above mentioned recent results. The complete derivation is provided by considering the structure of the root system. Furthermore, if X, Y, and Z are three generators of the Cartan-Weyl basis, we find, for a wide class of cases, W, a linear combination of X, Y and Z, such that exp(X) exp(Y) exp(Z) = exp(W). It turns out that the relevant commutator algebras are type 1c-i, type 4 and type 5. A key result concerns an iterative application of the algorithm leading to relevant extensions of the cases admitting closed forms of the BCH formula. Here we provide the main steps of such an iteration that will be developed in a forthcoming paper. (orig.)

    Water in caves, discharging from springs, and flowing in streams in the upper Baker and Snake Creek drainages are important natural resources in Great Basin National Park, Nevada. Water and rock samples were collected from 15 sites during February 2009 as part of a series of investigations evaluating the potential for water resource depletion in the park resulting from the current and proposed groundwater withdrawals. This report summarizes general geochemical characteristics of water samples collected from the upper Baker and Snake Creek drainages for eventual use in evaluating possible hydrologic connections between the streams and selected caves and springs discharging in limestone terrain within each watershed.Generally, water discharging from selected springs in the upper Baker and Snake Creek watersheds is relatively young and, in some cases, has similar chemical characteristics to water collected from associated streams. In the upper Baker Creek drainage, geochemical data suggest possible hydrologic connections between Baker Creek and selected springs and caves along it. The analytical results for water samples collected from Wheelers Deep and Model Caves show characteristics similar to those from Baker Creek, suggesting a hydrologic connection between the creek and caves, a finding previously documented by other researchers. Generally, geochemical evidence does not support a connection between water flowing in Pole Canyon Creek to that in Model Cave, at least not to any appreciable extent. The water sample collected from Rosethorn Spring had relatively high concentrations of many of the constituents sampled as part of this study. This finding was expected as the water from the spring travelled through alluvium prior to being discharged at the surface and, as a result, was provided the opportunity to interact with soil minerals with which it came into contact. Isotopic evidence does not preclude a connection between Baker Creek and the water discharging from

  13. Volcanic Risk Perception and Preparedness in Communities within the Mount Baker and Glacier Peak Lahar Hazard Zones

    2014-12-01

    A community's ability to effectively respond to and recover from natural hazards depends on both the physical characteristics of the hazard and the community's inherent resilience. Resilience is shaped by a number of factors including the residents' perception of and preparedness for a natural hazard as well as the level of institutional preparedness. This study examines perception of and preparedness for lahar hazards from Mount Baker and Glacier Peak in Washington's Skagit Valley. Through an online survey, this study isolates the influence of specific variables (e.g., knowledge, past experience, scientific background, trust in various information sources, occupation, self-efficacy, sense of community) on risk perception and explores reasons behind the frequent disconnect between perception and preparedness. We anticipate that individuals with more extensive education in the sciences, especially geology or earth science, foster greater trust in scientists and a more accurate knowledge, understanding, and perception of the volcanic hazards in their community. Additionally, little research exists examining the extent to which first responders and leaders in response-related institutions prepare on a personal level. Since these individuals work toward community preparedness professionally, we hypothesize that they will be more prepared at home than members of the general public. Finally, the Skagit Valley has a significant history of flooding. We expect that the need to respond to and recover from frequent flooding creates a community with an inherently higher level of preparedness for other hazards such as lahars. The results of this study will contribute to the understanding of what controls risk perception and the interplay between perception and preparedness. At a broader level, this study provides local and state-level emergency managers information to evaluate and improve response capabilities and communication with the public and key institutions in order to

    Full Text Available Mlh1-Mlh3 is an endonuclease hypothesized to act in meiosis to resolve double Holliday junctions into crossovers. It also plays a minor role in eukaryotic DNA mismatch repair (MMR. To understand how Mlh1-Mlh3 functions in both meiosis and MMR, we analyzed in baker's yeast 60 new mlh3 alleles. Five alleles specifically disrupted MMR, whereas one (mlh3-32 specifically disrupted meiotic crossing over. Mlh1-mlh3 representatives for each class were purified and characterized. Both Mlh1-mlh3-32 (MMR+, crossover- and Mlh1-mlh3-45 (MMR-, crossover+ displayed wild-type endonuclease activities in vitro. Msh2-Msh3, an MSH complex that acts with Mlh1-Mlh3 in MMR, stimulated the endonuclease activity of Mlh1-mlh3-32 but not Mlh1-mlh3-45, suggesting that Mlh1-mlh3-45 is defective in MSH interactions. Whole genome recombination maps were constructed for wild-type and MMR+ crossover-, MMR- crossover+, endonuclease defective and null mlh3 mutants in an S288c/YJM789 hybrid background. Compared to wild-type, all of the mlh3 mutants showed increases in the number of noncrossover events, consistent with recombination intermediates being resolved through alternative recombination pathways. Our observations provide a structure-function map for Mlh3 that reveals the importance of protein-protein interactions in regulating Mlh1-Mlh3's enzymatic activity. They also illustrate how defective meiotic components can alter the fate of meiotic recombination intermediates, providing new insights for how meiotic recombination pathways are regulated.

  15. Preparing for Volcanic Hazards: An Examination of Lahar Knowledge, Risk Perception, and Preparedness around Mount Baker and Glacier Peak, WA

    2015-12-01

    As the number of people living at risk from volcanic hazards in the U.S. Pacific Northwest continues to rise, so does the need for improved hazard science, mitigation, and response planning. The effectiveness of these efforts relies not only on scientists and policymakers, but on individuals and their risk perception and preparedness levels. This study examines the individual knowledge, perception, and preparedness of over 500 survey respondents living or working within the lahar zones of Mount Baker and Glacier Peak volcanoes. We (1) explore the common disconnect between accurate risk perception and adequate preparedness; (2) determine how participation in hazard response planning influences knowledge, risk perception, and preparedness; and (3) assess the effectiveness of current lahar hazard maps for public risk communication. Results indicate that a disconnect exists between perception and preparedness for the majority of respondents. While 82% of respondents accurately anticipate that future volcanic hazards will impact the Skagit Valley, this knowledge fails to motivate increased preparedness. A majority of respondents also feel "very responsible" for their own protection and provision of resources during a hazardous event (83%) and believe they have the knowledge and skills necessary to respond effectively to such an event (56%); however, many of these individuals still do not adequately prepare. When asked what barriers prevent them from preparing, respondents primarily cite a lack of knowledge about relevant local hazards. Results show that participation in response-related activities—a commonly recommended solution to this disconnect—minimally influences preparedness. Additionally, although local hazard maps successfully communicate the primary hazard—97% of respondents recognize the lahar hazard—many individuals incorrectly interpret other important facets of the maps. Those who participate in response-related activities fail to understand these

    The monoecious, bird-pollinated epiphytic Tillandsia achyrostachys E. Morr. ex Baker var. achyrostachys is an endemic bromeliad of the tropical dry forests of Mexico with clonal growth. In the Sierra de Huautla Natural Reserve this species shows a host preference for Bursera copallifera (Sessé & Moc ex. DC) Bullock. As a result of deforestation in the study area, B. copallifera has become a rare tree species in the remaining forest patches. This human-induced disturbance has directly affected the population densities of T. achyrostachys. In this study the genetic consequences of habitat fragmentation were assessed by comparing the genetic diversity, gene flow and genetic differentiation in six populations of T. achyrostachys in the Sierra de Huautla Natural Reserve, Mexico. Allozyme electrophoresis of sixteen loci (eleven polymorphic and five monomorphic) were used. The data were analysed with standard statistical approximations for obtaining diversity, genetic structure and gene flow. Genetic diversity and allelic richness were: HE = 0.21 +/- 0.02, A = 1.86 +/- 0.08, respectively. F-statistics revealed a deficiency of heterozygous plants in all populations (Fit = 0.65 +/- 0.02 and Fis = 0.43 +/- 0.06). Significant genetic differentiation between populations was detected (Fst = 0.39 +/- 0.07). Average gene flow between pairs of populations was relatively low and had high variation (Nm = 0.46 +/- 0.21), which denotes a pattern of isolation by distance. The genetic structure of populations of T. achyrostachys suggests that habitat fragmentation has reduced allelic richness and genetic diversity, and increased significant genetic differentiation (by approx. 40 %) between populations. The F-statistic values (>0) and the level of gene flow found suggest that habitat fragmentation has broken up the former population structure. In this context, it is proposed that the host trees of T. achyrostachys should be considered as a conservation priority, since they represent the

    In tequila production, fermentation is an important step. Fermentation determines the ethanol productivity and organoleptic properties of the beverage. In this study, a yeast isolated from native residual agave must was identified as Kluyveromyces marxianus UMPe-1 by 26S rRNA sequencing. This yeast was compared with the baker's yeast Saccharomyces cerevisiae Pan1. Our findings demonstrate that the UMPe-1 yeast was able to support the sugar content of agave must and glucose up to 22% (w/v) and tolerated 10% (v/v) ethanol concentration in the medium with 50% cells survival. Pilot and industrial fermentation of agave must tests showed that the K. marxianus UMPe-1 yeast produced ethanol with yields of 94% and 96% with respect to fermentable sugar content (glucose and fructose, constituting 98%). The S. cerevisiae Pan1 baker's yeast, however, which is commonly used in some tequila factories, showed 76% and 70% yield. At the industrial level, UMPe-1 yeast shows a maximum velocity of fermentable sugar consumption of 2.27g·L(-1)·h(-1) and ethanol production of 1.38g·L(-1)·h(-1), providing 58.78g ethanol·L(-1) at 72h fermentation, which corresponds to 96% yield. In addition, the major and minor volatile compounds in the tequila beverage obtained from UMPe-1 yeast were increased. Importantly, 29 volatile compounds were identified, while the beverage obtained from Pan1-yeast contained fewer compounds and in lower concentrations. The results suggest that the K. marxianus UMPe-1 is a suitable yeast for agave must fermentation, showing high ethanol productivity and increased volatile compound content comparing with a S. cerevisiae baker's yeast used in tequila production.

    Full Text Available Moringa stenopetala (Baker f. Cufod. is a medicinal plant that has been used in Ethiopian traditional medicine as a remedy for treatment of hypertension and diabetes. The aim of this study was to evaluate antihypertensive and antihyperlipidemic effect in fructose induced hypertensive rats.Rats were randomly divided into control and treatment groups (n=6. Treatment groups were given daily extracts (250, 500, and 1000 mg/kg orally with fructose. Whereas, positive, negative and normal control groups were received captopril (20 mg/kg/day with fructose, only fructose (66% w/v ad libitum and distilled water ad libitum for 15 days, respectively. The blood pressure was measured every 5th day using tail cuff blood pressure analyzer, and on the 16th day the blood was sampled to evaluate antihyperlipidemic effect using clinical chemistry analyzer. The study showed that aqueous and 70% ethanol extracts significantly prevented blood pressure increment in a dose dependent manner comparable to that of the standard drug. Similarly, the extracts suppressed increment in lipid profile (cholesterol, glucose and triglycerides compared with negative control. The biochemical test revealed that extracts produced a rise in liver but no effect on kidney function indicators compared with normal control.These findings revealed that both crude extracts of Moringa stenopetala (Baker f. Cufod. possess antihypertensive and antihyperlipidemic effect.

    To describe our experience with cisplatin- and paclitaxel-based IP chemotherapy in patients treated initially with either neoadjuvant chemotherapy and interval debulking surgery (IDS) or primary cytoreductive surgery (PCRS). We performed a retrospective review of the records of 67 patients (38 IDS, 29 PCRS) enrolled in the intraperitoneal (IP) chemotherapy program at the Tom Baker Cancer Centre between 2006 and 2009. Information pertaining to patient demographics, IP chemotherapy toxicity, and catheter complications was extracted, and the median time to recurrence was calculated. Most patients in the study were aged 50 to 70 years and had a diagnosis of stage III serous ovarian cancer. Overall, 295/393 IP cycles (75%) were successfully administered. The proportion of patients completing six cycles of chemotherapy in the IDS and PCRS groups was 53% and 59%, respectively. Frequent (> 25%) Grade 1 to 2 chemotherapy toxicities included fatigue, peripheral neuropathy, and nausea. Catheter complications were observed in 34% of patients (23/67). The recurrence rates for patients completing four or more cycles of IP chemotherapy in the IDS and PCRS groups were 58% and 35%, respectively, with the median time to recurrence approximately one year. Although IP chemotherapy is well tolerated in both IDS and PCRS patients, the median time to recurrence is shorter than expected.

  7. Heat recovery and energy saving using a Baker Perkins Simplex 2000 bread baking oven. A demonstration at Mothers Pride Bakery. (Nottingham)

    The first installation of a new type of British bread oven capable of producing 6,800 loaves/hour has reduced energy costs at British Bakeries' Watnall plant by Pound 45,900/year, including Pound 23,500/year due to the inclusion of heat recovery equipment on the oven. Additional benefits of this new oven include reduced production labour requirements - a reduction of one man per shift due to automatic handling of the bread-tin lids - and an increase in productivity of 100% compared with previous models. The new oven - a Baker Perkins Simplex 2000 - is indirect-fired which means that the burners can use either gas or oil without fear of contamination of the product. A new layout of the burners gives a better heat distribution than in previous models, thus requiring less fuel to achieve a given temperature in each zone. In addition there is heat recovery from both the combustion flue products and the oven chamber exhaust. The prover is heated by means of hot water coils using recovered heat from the oven exhaust. The combustion flue products are used to provide some pre-heating of the combustion air. (author).

The transformation of (1) into the corresponding dehydro chalcone (2) through biohydrogenation reactions was carried out in n-hexane at 25 or 35 deg C, for 4-48 h reaction. The product conversion, under different experimental conditions, was evaluated by hydrogen nuclear magnetic resonance, 1 H NMR.The highest conversion degrees were achieved using BY immobilized in agar gel, (29-47%), depending also on the temperature. Using BY immobilized in PEO, PVA, SC and G films, the conversion into (2) was lower (0-21%). The results show the feasibility of the use of BY immobilized in polymeric materials to reduce a,b-unsaturated carbonyl compounds. (author)

    Full Text Available Background: Tyrosinase is a key enzyme in melanin synthesis from tyrosine. To prevent or treat pigmentation disorders, tyrosinase inhibitors have been used increasingly for medicinal and cosmetic products. The aim of this study is to evaluate inhibitory effects of Urginea maritima (L. Baker, Zhumeria majdae Rech.f. & Wendelbo and Physalis divaricata D.Don on mushroom tyrosinase. Methods: The inhibitory activities of the hydroalcoholic extracts of plants against oxidation of L-DOPA (as a substrate by mushroom tyrosinase were investigated. The amount of formed DOPAchrome was determined at 475 nm as optical density. Results: The extracts showed anti-tyrosinase activity weaker than positive control (Kojic acid. The inhibitory activity of tested plants: U.maritima, Z.majdae and P.divaricata against mushroom tyrosinase were 38.61, 29.70 and 25.74 % at 1.67 mg/mL, respectively. Conclusion: The most tyrosinase inhibitory activity was seen for U.maritima. However more investigations on human tyrosinase, toxicological and clinical studies are needed to confirm its activity.

    Reconstructions of dry western US forests in the late 19th century in Arizona, Colorado and Oregon based on General Land Office records were used by Williams & Baker (2012; Global Ecology and Biogeography, 21, 1042–1052; hereafter W&B) to infer past fire regimes with substantial moderate and high-severity burning. The authors concluded that present-day large, high-severity fires are not distinguishable from historical patterns. We present evidence of important errors in their study. First, the use of tree size distributions to reconstruct past fire severity and extent is not supported by empirical age–size relationships nor by studies that directly quantified disturbance history in these forests. Second, the fire severity classification of W&B is qualitatively different from most modern classification schemes, and is based on different types of data, leading to an inappropriate comparison. Third, we note that while W&B asserted ‘surprising’ heterogeneity in their reconstructions of stand density and species composition, their data are not substantially different from many previous studies which reached very different conclusions about subsequent forest and fire behaviour changes. Contrary to the conclusions of W&B, the preponderance of scientific evidence indicates that conservation of dry forest ecosystems in the western United States and their ecological, social and economic value is not consistent with a present-day disturbance regime of large, high-severity fires, especially under changing climate

    Surface and laboratory Nuclear Magnetic Resonance (NMR) measurements combined with transient electromagnetic (TEM) data are powerful tools for subsurface water detection. Surface NMR (sNMR) and TEM soundings, laboratory NMR, complex resistivity, and X-Ray Diffraction (XRD) analysis were all conducted to characterise the distribution of water within Sherman Crater on Mt. Baker, WA. Clay rich rocks, particularly if water saturated, can weaken volcanoes, thereby increasing the potential for catastrophic sector collapses that can lead to far-travelled, destructive debris flows. Detecting the presence and volume of shallow groundwater is critical for evaluating these landslide hazards. The TEM data identified a low resistivity layer (conditions which would allow for sNMR detection of the clay layer are investigated. Using current instrumentation the combined analysis of the TEM and sNMR data allow for valuable characterisation of the groundwater system in the crater. The sNMR is able to reduce the uncertainty of the TEM in regards to the presence of a bulk water layer, a valuable piece of information in hazard assessment.

  12. An automatic driving system for a Baker's garlic [Allium chinense] planter: Development of the infrared beam guidance system

    2002-01-01

    We have developed a tractor attachment type semi-automatic Baker's garlic (shallot) planter to save hard labor requirement during planting. The velocity of the tractor in operation is so slow (2 to 3m/min) that the tractor driver is forced to tie his hands for a long time. This is an obstacle to its diffusion, because farm managers have to drive their own tractors by themselves in most Japanese farmhouses, yet they have to do other jobs during the planting season. We designed a new automatic driving system that consists of one infrared beam radiator and two infrared beam receivers to solve this problem. The infrared radiator is located in front of the tractor and shows the infrared guideline of tractor path. The infrared receivers are equipped on the front of the tractor and detect the infrared from the radiator. The receivers are arranged symmetrically at 4.5 degree from the center of the tractor. So the misalignment of the tractor creates a difference in sensitivity and it is possible to distinguish the tractor direction against the infrared beam. This system was tested under the sand dune field conditions with the tractor that was converted to automatic driving. The results show the system can effectively steer about 80 m automatically with an almost straight path, and the error from the starting point is within 0.1 m

    Dowex anion exchanger-immobilized-baker's yeast [Dae-yeast] were synthesized and potentially applied as environmental friendly biosorbents to evaluate the up-take process of anionic and cationic mercury(II) species as well as other metal ions. Optimization of mass ratio of Dowex anion exchanger versus yeast (1:1-1:10) in presence of various interacting buffer solutions (pH 4.0-9.0) was performed and evaluated. Surface modification of [Dae-yeast] was characterized by scanning electron microscopy (SEM) and infrared spectroscopy. The maximum metal biosorption capacity values of [Dae-yeast] towards mercury(II) were found in the range of 0.800-0.960, 0.840-0.950 and 0.730-0.900 mmol g -1 in presence of buffer solutions pH 2.0, 4.0 and 7.0, respectively. Three possible and different mechanisms are proposed to account for the biosorption of mercury and mercuric species under these three buffering conditions based on ion exchange, ion pair and chelation interaction processes. Factors affecting biosorption of mercury from aqueous medium including the pH effect of aqueous solutions (1.0-7.0), shaking time (1-30 min) and interfering ions were searched. The potential applications of modified biosorbents for selective biosorption and extraction of mercury from different real matrices including dental filling waste materials, industrial waste water samples and mercury lamp waste materials were also explored. The results denote to excellent percentage extraction values, from nitric acid as the dissolution solvent with a pH 2.0, as determined in the range of 90.77-97.91 ± 3.00-5.00%, 90.00-93.40 ± 4.00-5.00% and 92.31-100.00 ± 3.00-4.00% for the three tested samples, respectively.

    Purpose: This retrospective study aims to quantify the positional accuracy of seed delivery in permanent breast seed implant (PBSI) brachytherapy at the Tom Baker Cancer Centre (TBCC). Methods: Treatment planning and post-implant CT scans for 5 patients were rigidly registered using the MIM Symphony™ software (MIM Software, Cleveland, OH) and used to evaluate differences between planned and implanted seed positions. Total and directional seed displacements were calculated for each patient in a clinically relevant ‘needle coordinate system’, defined relative to the angle of fiducial needle insertion. Results: The overall average total seed displacement was 10±8 mm. Systematic seed displacements were observed in individual patients and the magnitude and direction of these offsets varied among patients. One patient showed a significant directional seed displacement in the shallow-deep direction compared with the other four patients. With the exception of this one patient outlier, no significant systematic directional displacements in the needle coordinate system were observed for this cohort; the average directional displacements were −1±5 mm, 2±3 mm, and −2±4 mm in the shallow-deep, up-down, and right-left directions respectively. Conclusion: With the exception of one patient outlier, the magnitude of seed displacements were relatively consistent among patients. The results indicate that the shallow-deep direction possesses the largest uncertainty for the seed delivery method used at the TBCC. The relatively large uncertainty in seed placement in this direction is expected, as this is the direction of needle insertion. Further work will involve evaluating deflections of delivered needle tracks from their planned positions.

  16. Identification of up-regulated genes from the metal-hyperaccumulator aquatic fern Salvinia minima Baker, in response to lead exposure.

    Lead (Pb) is one of the most serious environmental pollutants. The aquatic fern Salvinia minima Baker is capable to hyper-accumulate Pb in their tissues. However, the molecular mechanisms involved in its Pb accumulation and tolerance capacity are not fully understood. In order to investigate the molecular mechanisms that are activated by S. minima in response to Pb, we constructed a suppression subtractive hybridization library (SSH) in response to an exposure to 40μM of Pb(NO 3 ) 2 for 12h. 365 lead-related differentially expressed sequences tags (ESTs) were isolated and sequenced. Among these ESTs, 143 unique cDNA (97 were registered at the GenBank and 46 ESTs were not registered, because they did not meet the GenBank conditions). Those ESTs were identified and classified into 3 groups according to Blast2GO. In terms of metabolic pathways, they were grouped into 29 KEGG pathways. Among the ESTs, we identified some that might be part of the mechanism that this fern may have to deal with this metal, including abiotic-stress-related transcription factors, some that might be involved in tolerance mechanisms such as ROS scavenging, membrane protection, and those of cell homeostasis recovery. To validate the SSH library, 4 genes were randomly selected from the library and analyzed by qRT-PCR. These 4 genes were transcriptionally up-regulated in response to lead in at least one of the two tested tissues (roots and leaves). The present library is one of the few genomics approaches to study the response to metal stress in an aquatic fern, representing novel molecular information and tools to understand the molecular physiology of its Pb tolerance and hyperaccumulation capacity. Further research is required to elucidate the functions of the lead-induced genes that remain classified as unknown, to perhaps reveal novel molecular mechanisms of Pb tolerance and accumulation capacity in aquatic plants.

  17. Capacity of the aquatic fern (Salvinia minima Baker) to accumulate high concentrations of nickel in its tissues, and its effect on plant physiological processes

    Highlights: • We document the capacity of an aquatic fern to hyper-accumulate Ni. • Effects of high Ni concentrations uptake on plant performance is documented. • High concentration of Ni in tissues damage photosynthesis. • Damage is related to carboxylation mechanisms than to electron transfer efficiency. • S. minima is a good candidate for remediation of water bodies contaminated with Ni. - Abstract: An experiment was designed to assess the capacity of Salvinia minima Baker to uptake and accumulate nickel in its tissues and to evaluate whether or not this uptake can affect its physiology. Our results suggest that S. minima plants are able to take up high amounts of nickel in its tissues, particularly in roots. In fact, our results support the idea that S. minima might be considered a hyper-accumulator of nickel, as it is able to accumulate 16.3 mg g{sup −1} (whole plant DW basis). Our results also showed a two-steps uptake pattern of nickel, with a fast uptake of nickel at the first 6 to 12 h of being expose to the metal, followed by a slow take up phase until the end of the experiment at 144 h. S. minima thus, may be considered as a fern useful in the phytoremediation of residual water bodies contaminated with this metal. Also from our results, S. minima can tolerate fair concentrations of the metal; however, at concentrations higher than 80 μM Ni (1.5 mg g{sup −1} internal nickel concentration), its physiological performance can be affected. For instance, the integrity of cell membranes was affected as the metal concentration and exposure time increased. The accumulation of high concentrations of internal nickel did also affect photosynthesis, the efficiency of PSII, and the concentration of photosynthetic pigments, although at a lower extent.

    1993-12-01

    Full Text Available Octanoic acid inhibited ethanolic fermentation by Saccharomyces cerevisiae (bakers yeast and the trehalose accumulation, however did not affect the endogenous degradation of trehalose. This inhibition may be explained by the binding of octanoic acid to hexokinase or other proteins of plasma membrane because they are not necessary for endogenous fermentation. The degradation of trehalose may be due to an activation of trehalase.A adição de ácido octanóico inibiu a fermentação alcoólica realizada por Saccharomyces cerevisiae (levedura de panificação e o acúmulo de trealose, contudo não afetou a degradação endógena de trealose. Esta inibição poderia ser explicada pela ligação do ácido octanóico a hexoquinase ou outra proteína da membrana plasmática porque não são necessárias para a fermentação endógena. A degradação da trealose poderia ser devida a uma ativação da trealase.

  5. Interview with Pennsylvania PUC chairman Susan M. Shanaman

    Utroska, D.

    1981-01-01

    Chairman Shanaman notes that Pennsylvania law justifies the Public Utility Commission (PUC) refusal to charge ratepayers for the cost of Three Mile Island units 1 and 2, neither of which are providing service, because ratepayers are already paying the costs of replacement power. The PUC chairman points to other service territories around the country where rates are kept below national averages because the average income level is low. The Metropolitan Edison Company is seeking Federal relief as well as legislative permission to put TMI-1 back into the rate base in fairness to ratepayers, but the PUC does not see bankruptcy for the utility as an appropriate way to force Federal assistance. The Administration needs to understand the local impact of Federal policies, especially those which are incompatible with state situations. Appropriate involvement includes nuclear waste research and underwriting some of the cleanup costs of onsite accidents that are too large for a single utility to handle. Chairman Shanaman feels that ratepayers should contribute to the insurance premium for future accidents, but not retroactively to support TMI-2. Nuclear power plant construction in the US will not progress until the issues of TMI-2 are resolved

    Full Text Available Con un microperfilador SCAMP (Self Contained Autonomous MicroProfile se detectó un proceso de Doble Difusión Convectiva (DDC, en los canales Martínez y Baker de la Patagonia central, Chile. Este perfilador midió temperatura y salinidad en la columna de agua con una resolución del orden de milímetros. El muestreo se efectuó en diciembre 2011, en 19 estaciones oceanográficas de ~55 m de profundidad. Los registros del microperfilador permitieron detectar la formación de escaleras termohalinas que caracterizan la formación de la DDC. Por medio del ángulo de Turner se confirmó que debajo de una capa superficial fuertemente estratificada (7-10 m se registraron eventos de DDC a profundidades entre 15 y 45 m. La DDC fue débil en la mayoría de los registros pero se evidenciaron eventos fuertes entre 15 y 40 m. En la capa subsuperficial, su origen se debió al intercalamiento de las masas aguas estuarinas (aguas frías y menos saladas encima de las oceánicas (aguas más cálidas y saladas, mientras que en la superficie la interacción océano-atmósfera favoreció su ocurrencia. La DDC en conjunto con el viento, las mareas y las ondas internas, puede constituir un mecanismo importante para la mezcla vertical, influenciando los flujos de calor, el hábitat de las especies marinas en estas profundidades y la exportación de carbono hacia los sedimentos.

    The gamma radiation has been used in several places of the World as a sterilization method, preservation and pasteurization of foodstuffs, effect which is achieved due to diminishing or elimination of the microorganisms, reaching every time more acceptance, moreover eliminates the uses of toxic and carcinogenic substances, of general use, but at the present, being in the process of being totally prohibited, due to the higher risk in the human health. In this work the related results with the effects of the gamma radiation are presented, coming from a {sup 60} Co source, in commercial wheat flour exposed to a dose of 1.0 KGy. The used dose is that allowed according to the NOM-033-SSA1-1993 standard. It was determined that the chemical characteristics of humidity, protein and ashes were not affected by radiation. The rheological properties neither suffer severe effects as consequence of radiation; the pharynographic and alveographic parameters were lightly affected by the treatment. Significant changes were detected in the percentage of water absorption and in the tolerance index to mixing. However a diminish of 10% in the development time and an increase of 13% in the stability was observed, for the irradiated samples respect to the those samples not irradiated. In relation to the alveograph parameters it was only detected a diminish of 7% in the force parameter (w) without changes in the tenacity/blowing up index ratio (P/L). The fall number diminish 11% indicating a small diminution in viscosity. The bakering properties do not turn out modified by the irradiation treatment finding a specific weight of 4.6 and 4.5 (cm{sup 3}/g) for the control and irradiated samples, respectively. In the mesophyll analysis it was found a diminish of 96% from the original charge in control samples, observing a diminution of 74 and 25% in yeasts and mushrooms respectively. Microbiologically it was determined absence of total coliforms bacteria and faecal coliforms in the control

    Full Text Available The short (40 pages pamphlet by Warren and Rose (1994 provides the answer to a complex question regarding credit for an important archaeological methodology, stratigraphic excavation. Let me set the stage for this appreciation. Continuing research on the beginnings of stratigraphic excavations in North America (Browman and Givens 1996, I sought the origins of the idea of actually excavating by strata, rather than post-facto interpretation, seen in North American as early as 1895 in the work of Henry Chapman Mercer, but not really introduced into the repertoire of American techniques until the work of Gamio, Kidder and Nelson between 1911 and 1914. The roots of the latter three seemed to lie with individuals such as Reisner, Boas, Uhle, who in turn seemed to rely on Hugo Obennaier, Gabriel de Mortillet, Marcellin Boule, and perhaps Pitt-Rivers, while Mercer's work could be traced to Boule and Albert Gaudry. Doggedly following back the roots, I found that Chapman (1989 could make a reasonable case that Pitt-Rivers had actually learned of the idea of strati­graphic excavation from Evans, Prestwich, and Lubbock, from the British scientists working with the Upper and Middle Paleolithic excavations during 1858-1868.

    Full Text Available RESUMEN: el artículo revisa algunos supuestos sobre la producción literaria de Raúl González Tuñón en las décadas de 1920 y 1930 a partir de dos desplazamientos. En primer lugar, explora las políticas de la literatura que permitirían pensar, de manera menos esquemática que con la habitual categoría de “literatura política” con que se suelen abordar sus textos de la década del treinta, las apuestas y limitaciones de una escritura que desde su inicio se propuso como transformadora. En segundo lugar, el artículo pone el foco en la primera circulación de los textos, muchas veces en diarios y revistas, contextos formativos de una literatura que en gran medida surgió en sus páginas. Desencuadernar a Tuñón implica atender a la materialidad de sus escritos y explorar más allá de la tradicional figura del autor de libros, para indagar políticas de la escritura que articularon campos y prácticas, y experimentaron no sólo con nuevas formas estéticas sino también con diversos modos de circulación pública de las letras.

    Full Text Available La Nueva Granada luego de su independencia del reino español vivió un sufrido proceso de maduración de sus instituciones políticas y administrativas en medio de arduas tensiones políticas y sociales. La forma de ser del Estado determinaría la manera en que los entes territoriales y administrativos condujeran los asuntos públicos, por eso mismo, la tensión entre adoptar un sistema de organización estatal unitario, con centralización política o preferir el sistema federal, se convirtió en una discusión permanente entre los hombres políticos de la época. Florentino González, fue protagonista de primer orden de esos debates y de manera erudita su pensamiento evolucionó en lo referente a la conveniencia del sistema federal para Colombia. Este artículo recoge el pensamiento de González sobre el tema con base en los escritos políticos, jurídicos e incluso de opinión publicados por el autor en libros y periódicos de la época, con la finalidad de ubicar los fundamentos teóricos y filosóficos de sus posturas intelectuales, las cuales sin duda contribuyeron a las reformas constitucionales que vivió nuestro país en aquella época y lo posiciona hoy en día como pionero del derecho administrativo en Colombia.

    Full Text Available This study was carried out to investigate the effects of adding baker yeast (BY, chlortetracycline (CTC and both BY + CTC to a control diet containing 200 ng/g of aflatoxin B1 (C + AFB1 on performance, serum parameters and pathologyc alterations of broilers. A total 100 chicks (Ross PM 3 were divided into five groups in individual cages and each containing 20 animals. BY, a rich source of protein and vitamin B complex, was mixed into the diets at 2.0 %, CTC was mixed into the diet at 2.5 ng/g. Feed consumption, body weight and feed efficiency were recorded weekly. Serum parameters and pathologyc alterations were determined at the end of the study. Dead animals were recorded daily. Liver changes were clearly apparent in the C+AFB1and C+ AFB1+CTC most of the livers were enlarged, yellow and had pethecial hemorrhages. Canalicula cholestosis was absent in group C+AFB1 and C+ AFB1+CTC, but not others. When compared to the control (C group, alkaline phosphatase (ALP, appear to be significantly increased in the C+AFB1 and C+CTC+ AFB1 groups. Serum glutamic oxalacetic transaminase (GOTwas increased in C+AFB1 birds. Serum alphaphetoprotein was not affected by the treatments. Feed consumption and body weight were significantly reduced in group AFB1. Birds receiving BY + AFB1, CTC + AFB1 and BY + CTC + AFB1 had a significantly higher body weight than group C+AFB1. Feed efficiency was better in group CTC + AFB1 than the others. The findings of this research suggest tha BY (2% can partly counteract some of the toxic effects of AFB1.Este estudo foi desenvolvido para avaliar os efeitos da adição de Levedura de panificação (BY e cortetraciclina (CTC e ambos BY+CTC a uma dieta controle © contendo 200 ng/g de aflatoxina B1 (C+AFB1 sobre desempenho, parâmetros séricos e alterações patológicas de frangos de corte.

    As Cornelius Riordan states in his round-table paper, "The challenge of effective and equitable schooling in the next century is to overcome the resistance and recalcitrance of youth cultures in and out of school" (p 58). While this is admittedly not a new problem, it is more complex in its modern form and innovative ways to solve it are needed. In an old tradition, one such attempt has been single-sex schools, which have had particular success with the disadvantaged and white females in American society, with the notable involvement of Catholic religious communities. The report does not make clear whether their successes can be reproduced in some modification of the public school format. However, the AAUW report on single-sex schools sheds light on some of the characteristics that make true learning communities out of ordinary schools and on what it takes to reach disadvantaged girls. For these reasons, the AAUW report is good reading for educators at all levels.

    Full Text Available Within the fields of educational and developmental psychology, interest has grown concerning the question of how cognitive and socioemotional processes work together to construct pathways for the self. In particular, researchers and educators have become increasingly interested in the role that the school plays in children's self-development. According to Jerome Bruner, "the single most universal thing about human experience is the phenomenon of the 'Self" (1996, p. 35 and advocates that education is crucial to its formation. However, despite the strong theoretical claims linking a child's sense of self to school experience, there has been a lack of systematic research on the self within the school context.

O objetivo deste experimento foi o de avaliar as características germinativas e o efeito de tratamentos pré-germinativos nas sementes da espécie. Primeiro, em um delineamento inteiramente casualizado, foram investigados seis tratamentos em quatro repetições de 25 sementes. Ostratamentos constaram da imersão em água destilada à temperatura ambiente (25 ± 1,5°C durante 24, 48 e 72h, imersão em água quente a 90°C durante 2 min. e imersão em ácido sulfúrico p.a. durante 2 min. e com posterior lavagem em água corrente por 24h que foram comparados com um controle. Depois de quatro meses de armazenamento, sementesintactas (controle foram comparadas com sementes imersas em água a 90°C por 2 min. Assim, a maior porcentagem de germinação (92% foi obtida com sementes recém-colhidas e imersas em água a 90oC durante 2 min., mas o armazenamento por quatro meses melhorou a porcentagem de germinação (G ≥ 96,0%. Os tempos médios de germinação não diferiram entre as sementes recém-colhidas (de 21,0 a 26,8 dias e as armazenadas (entre 18,4 e 19,5 dias. A germinação das sementes recém-colhidas e armazenadas foi lenta e distribuída ao longo do tempo experimental.Ananas ananassoides is a perennial plant with ornamental potential because of flowers and bracts with exuberant colors and herbaceous development where the leaves have spiny margins that are distributed in rosettes. The objective of this experiment with six completely randomized treatments and four replicates of 25 seeds was to evaluate the effects of seed soaking into distilled water at environmental temperature (25 ± 1.5°C for 24, 48, and 72h; seed soaking into water at 90°C for 2 minutes; seed soaking into sulfuric acid p.a. for 2 minutes followed by tap water washing for 24h, and the control. Thereafter, 4-month-old seeds were immersed into water at 90°C for 2 minutes and compared to the intact seeds (control. Initially, the highest percentage of germination (G=92% was evaluated in newly collected seeds that were immersed in water at 90°C for 2 minutes. No increases in the percentage of seed germination were detected by seed soaking into water or sulfuric acid in comparison to the seeds that were immersed in water at 90°C for 2 minutes. However, the percentage of germination was higher than 96% when the seeds were stored for four months. No difference in the mean time to germination was detected between newly collected (between 21.0 and 26.8 days and stored seeds (between 18.4 and 19.5 days. The germination of newly collected and stored seeds was slow and distributed throughout the experimental time.

    Full Text Available A espécie medicinal Vernonia condensata, vulgarmente conhecida por alumã, pertencente à família Asteraceae, possui propriedades analgésicas e de proteção gástrica. A crescente utilização dessa planta no Nordeste, pelas propriedades terapêuticas, justifica a necessidade de medidas que minimizem o impacto de sua exploração nas reservas naturais. O objetivo desse trabalho foi multiplicar in vitro plantas de alumã sob diferentes concentrações de BAP e aclimatá-las. Gemas axilares foram desinfestadas em solução de álcool etílico 70%, durante 2 minutos e em solução de hipoclorito de sódio (2% de cloro ativo na concentração de 3:1, durante 15 minutos, seguido de três lavagens em água destilada estéril. Os tratamentos para multiplicação consistiram em doses de BAP (0,0; 1,0; 2,0; 3,0; 4,0 e 5,0 mg L-1 em meio MS semi-sólido. O delineamento experimental foi o inteiramente casualizado, com 5 repetições, contendo 10 gemas por repetição. Após 30 dias de cultivo observou-se maior taxa de explantes responsivos, 84% na concentração de 1,0 mg L-1 de BAP, com produção de 4,0 brotos/explante. Nos tratamentos 3,0; 4,0 e 5,0 mg L-1 ocorreu hiperhidricidade nas folhas. As microplantas de alumã provenientes da metodologia utilizada neste trabalho alcançaram 100% de sobrevivência na aclimatação.The medicinal species Vernonia condensata, commonly known as "alumã", belongs to the family Asteraceae and has analgesic and gastric protective properties. The increasing use of this plant in the Northeast of Brazil due to its therapeutic properties justifies the need of measures to minimize the impact of its exploitation in natural reserves. The aim of this study was to multiply, in vitro, "alumã" plants under different BAP levels, acclimating them. Axillary buds were sterilized in 70% (v/v alcohol solution for 2 minutes and in 75% sodium hypochlorite solution (2% active chlorine at 3:1 concentration for 15 minutes, followed by three washings in sterile distilled water. Multiplication treatments consisted of different BAP levels (0.0; 1.0; 2.0; 3.0; 4.0 and 5.0 mg L-1 in semi-solid MS medium. The experimental design was completely randomized, with 5 replicates and 10 buds per replicate. After 30 days of cultivation, the highest rate of responsive explants was obtained: 84% at 1.0 mg L-1 BAP, producing 4.0 sprouts/explant. In the treatments 3.0, 4.0 and 5.0 mg L-1, there were vitrified leaves. The "alumã" microplants used in this study had 100% survival in acclimation.

    Comparative study was performed to emphasize the effects of using different nuclear data systems and methods on the various parameters of the fast reactor. Multigroup libraries as 11 (ANL-5800) and 26 (BNAB-64) energy group systems of nuclear data constants were used in the present work. The calculations were carried out for both infinite dilution (self-shielding factor F= 1) and self-shielded cross sections. Various computer codes were elaborated and derived to meet the conditional requirements for such calculations. The important output of these calculations are the neutron spectra, neutron balance, fission and capture rate distributions, critical mass, breeding ratio in each region and total breeding ratio of the reactor. Five different cases of study were considered employing two systems of constants, infinite dilution and self-shielded cross-sections and treating stainless steel of the reactor as to be substituted by iron. Moreover, calculations have been concerned for averaged one group nuclear data constants which were condensed from the 11 and 26 group systems. Comparisons of the multigroup results with those of the group were made. The condensation process for averaging to one group was done to estimate the effect of such physical simplification on the calculated parameters. The present work results have been compared with many published works. Fair agreements are obtained, which varified the consistance and completeness of the methods implemented and used

    The purpose of this study was to stimulate by gamma radiation the existing commercial types of yeast so as to obtain yeasts that would better reflect the substrate and have improved reproductive capacity. The experiments were conducted under ordinary conditions using commercial yeasts received from one factory producing alcohol and bakery yeasts and isolated as pure cultures. Irradiating yeast cultures with small doses (up to 10 krad) was found to stimulate the reproduction and fermenting activity of yeast cells as manifested in increased accumulation of yeast biomass and greater yield of ethyl alcohol.

    Full Text Available Las bromelias como plantas fitotelmas mantienen una compleja cadena trófica que incluye invertebrados asociados a depósitos de agua. Se determinó la comunidad de invertebrados acuáticos de la bromelia Tillandsia turneri en un bosque altoandino en el Municipio de Chocontá, Cundinamarca, Colombia. Se estudiaron 37 individuos de la bromelia ubicadas desde 0 hasta 6 m de altura, a las cuales se realizaron mediciones morfológicas, de contenido de agua y análisis fisicoquímico de esta y se colectaron los invertebrados asociados. Los órdenes mas abundantes fueron Coleóptera, Díptera y Cladócera; por medio de un análisis de similaridad de Morisita Horn se encontró que las bromelias son similares en cuanto a composición de invertebrados, por lo que se sugiere que pertenecen a un solo estrato dentro del bosque y que los procesos de ovoposición y dispersión para los grupos estudiados tienen igual probabilidad de ocurrir en las bromelias ubicadas de 0 a 6 m de altura.

    The main objective of current study is to elucidate taxonomic, pharmacognostic and physicochemical behavior of Colchicum luteum (Suranjantalkh) for its proper identification and authentication from its cheap and tasteless adulterant. Colchicum luteum is one of the most rare and hence expensive medicinal plants. It is an active part of many unani formulations due to presence of an alkaloid colchicine which is claimed to be effective in arthritis, gout, rheumatism and internal injuries. In order to overcome demand of its corm, suppliers and herb sellers adultered bulbs of a monocotyledon plant Narcissus tazetta. This type of study reveals to be helpful in differentiating plants on basis of leaf epidermal anatomy, palynology, phamacognosy and physicochemical values. It is an important step in field of herbal medicine to provide pure and original medicinal plants to yield their maximum effectiveness. (author)

    Engineered nanomaterials (ENMs) are increasingly incorporated into a variety of commercial applications and consumer products; however, ENMs may possess cytotoxic properties due to their small size. This study assessed the effects of two commonly used ENMs, zinc oxide nanoparticles (ZnONPs) and silver nanoparticles (AgNPs), in the model eukaryote Saccharomyces cerevisiae. A collection of ≈4600 S. cerevisiae deletion mutant strains was used to deduce the genes, whose absence makes S. cerevisiae more prone to the cytotoxic effects of ZnONPs or AgNPs. We demonstrate that S. cerevisiae strains that lack genes involved in transmembrane and membrane transport, cellular ion homeostasis, and cell wall organization or biogenesis exhibited the highest sensitivity to ZnONPs. In contrast, strains that lack genes involved in transcription and RNA processing, cellular respiration, and endocytosis and vesicular transport exhibited the highest sensitivity to AgNPs. Secondary assays confirmed that ZnONPs affected cell wall function and integrity, whereas AgNPs exposure decreased transcription, reduced endocytosis, and led to a dysfunctional electron transport system. This study supports the use of S. cerevisiae Gene Deletion Array as an effective high-throughput technique to determine cellular targets of ENM toxicity.

    4 genotypes of wheat of the 25 included in the regional tests of the highland Cundiboyacense area; were used to determine the phenotypic stability through 21 environments (town for semester), of 5 characteristics of quality by means of 5 methodologies, to specify which or which kept bigger relationship with the procedure used by the program of wheat of the ICA of them, and to compare the average through all the environment with the average of witness, to decide the commercialization of a given genotype. For all the characteristics, 2 or more than the 5 studied methods they were coincident in identifying the genotype of better stability. The 5 methods for the factors, hecto liter weighs and extraction of flour, and the methods of the covalence of Finlay and Wilkinson and of Eberhart and Russell for the characteristic of volume of the bread, they always included Samaca 68 like one of the genotypes wanted by their stability. The last 3 mentioned factors of quality are the important, from the industrial point of view. The methods of Finlay and Wilkinson and of Eberhart and Rusell they also classified to the variety Samaca68 as of general adaptability for the variable extraction of flour and volume of the bread. The selection of Samaca68 for their stability and adaptability was, then, quite concordant with that carried out by the Program of Wheat of the ICA, since this variety was for a lot of time the national witness of quality

  15. Thermoluminescent response of dosemeters TLD-100 exposed to distinct baker protocols, irradiation and reading

    International Nuclear Information System (INIS)

    Estrada E, D.

    2002-01-01

    The interest that motivated the realization of this work is the opposing discrepancy among the values of the efficiency thermoluminescent of heavy charged particles (PCP) regarding gamma radiation (η PCP , γ) reported in different works and gathered recently for Horowitz (Ho 01). The measures of relative thermoluminescent efficiency have importance in relation to the dosimetry associated to medical therapy with heavy charged particle. The measurement of η PCP , γ depends of multiple experimental factors. To understand this dependence it was quantified the effect of using different procedures experimental in the estimate of the relative thermoluminescent efficiency of dosemeters TLD-100 (LiF: Ti; Mg) for protons of 3 MeV regarding gamma rays of 60 Co (η PCP , γ), varying the lot, the presentation, the one baked and the team reader. When was used the same global procedure values they were obtained for (η PCP , γ) inside the interval [0.30, 0.58] for the peak 5 and [0.35, 0.76] for the total thermoluminescent signal (Tl). At the use different equipment, baked and lot are obtained maximum differences of 30%, 12% and 6% respectively in the values of (η PCP , γ) for the peak 5, and 25%, 28% and 7% for the total Tl signal. The changes more significant of 36% and 44% for peak 5 and total signal respectively are obtained when changing the presentation of the dosemeter. As a complementary investigation it was studied the distribution of the Tl signal of each peak in the deconvolution of the curve of brightness with regard to the total signal in exposed dosemeters to high fluence of protons (1x10 10 p/cm 2 ) varying the experimental protocol. It was found that the distribution of the Tl signal has a difference of the order of 5% when changing the used reading team. It was observed that the contribution of the peak 5 regarding the total signal are preserved when changing baked and that it results to be 8% greater for the presentation in dosemeters of 1 x 1 x 1 mm 3 that for dosemeters of 0.89 x 3.17 x 3.17 mm 3 of TLD-100. Given the importance of having values of relative thermoluminescent efficiency reliable in applications associated to medical dosimetry, the main conclusion of this work is the recommendation of measuring relative efficiencies following a protocol of careful work and previously defined so much for the charged particle radiation as for the gamma radiation and controlling all the experimental factors involved.

    This work aims to study the production of the biomass of S. cerevisiae on an optimized medium using date extract as the only carbon source in order to obtain a good yield of the biomass. The biomass production was carried out according to the central composite experimental design (CCD) as a response surface methodology using Minitab 16 software. Indeed, under optimal biomass production conditions, temperature (32.9 °C), pH (5.35) and the total reducing sugar extracted from dates (70.93 g/L), S. cerevisiae produced 40 g/L of their biomass in an Erlenmeyer after only 16 h of fermentation. The kinetic performance of the S. cerevisiae strain was investigated with three unstructured models i.e., Monod, Verhulst, and Tessier. The conformity of the experimental data fitted showed a good consistency with Monod and Tessier models with R² = 0.945 and 0.979, respectively. An excellent adequacy was noted in the case of the Verhulst model ( R² = 0.981). The values of kinetic parameters ( Ks , X m , μ m , p and q ) calculated by the Excel software, confirmed that Monod and Verhulst were suitable models, in contrast, the Tessier model was inappropriately fitted with the experimental data due to the illogical value of Ks (-9.434). The profiles prediction of the biomass production with the Verhulst model, and that of the substrate consumption using Leudeking Piret model over time, demonstrated a good agreement between the simulation models and the experimental data.

    Del género Furcraea hacen parte especies textiles de gran importancia en los mercados nacionales e internacionales, tanto por las características de la fibra como por el contenido de precursores de hormonas, corticoides, azúcares, ácidos grasos y biopesticidas que se encuentran en sus jugos. En esta investigación se desarrolló un protocolo para la micropropagación de Furcraea macrophylla B. a partir de ápices caulinares procedentes de bulbillos. Los cultivos in vitro se realizaron en medio MS modificado y suplementado con BA, TDZ, KIN y 2-IP en forma individual o en combinación con 2,69 μM de ANA. Después de 12 semanas de iniciados los cultivos, en la mayoría de los tratamientos ensayados los explantes desarrollaron brotes axilares. 100% de los brotes producidos enraizaron después de 30 d en medio MS modificado suplementado con  11,42 μM de AIA, con 2,46 μM de AIB o en ausencia de reguladores de crecimiento. Después de la etapa de endurecimiento, 94% de las plántulas sobrevivieron en condiciones ex vitro. El protocolo establecido para la  micropropagación de F. macrophylla es un procedimiento efectivo con el que se podría suplir la demanda comercial de material vegetal seleccionado, en óptimo estado fitosanitario, en periodos relativamente  cortos y a bajos costos.

    The purpose of this study was to examine patterns and predictors of complementary and alternative medicine (CAM) among breast cancer patients. A review of the existing survey literature on CAM use for breast cancer was conducted with a series of eight focus groups (N = 67) to further examine the perspectives of breast cancer patients on CAM. The rates of CAM use varied from 17 to 75%, with a mean of 45%. Vitamins and minerals and herbs were the most frequently cited categories. Users tended to be younger, more educated, and more likely to have used CAM prior to their diagnosis. Focus group data indicate that breast cancer patients use a wide array of CAM for a variety of reasons, including symptom management, improving quality of life, and enhancing immune function. Although women rely on a variety of resources for information, they frequently experience frustration owing to the absence or conflicting nature of such information. Communication with conventional providers about CAM is frequently experienced as either unsupportive or not helpful by many patients. The results point to the value of developing better evidence-based informational resources related to CAM and cancer and the need for physicians to become better educated about CAM and how to communicate more effectively with their breast cancer patients about it.

During the past few years, the natural populations of this species have been depleted mainly by uncontrolled fishery, and because of environmental degradation and pollution by pesticides and detergents. In the present study, we carried out the histological and morphological characterization of the reproductive system of P. patula catemacensis under laboratory conditions. We found that the reproductive development of this snail depended more on the size than on the age the animals, and identified four development main stages, both for males and females. The main stages and their mean lengths ± confidence interval at P < 0.05 were (1 immature or not differenced (from 0.72 to 7 mm, (2 early maturation (from 18.95 ± 1.96 mm, (3 intermediate maturation (from 29.29 ± 4.9 mm, and (4 full maturity (from 35.89 ± 3.92 mm.

Vernonia oxylepis é uma dessas espécies e o objetivo desse estudo foi descrever a morfoanatomia da raiz tuberosa e a formação das gemas nessa raiz. Tal raiz é constituída de um eixo orientado perpendicularmente no solo, a partir do qual ramos aéreos são formados na porção proximal, situada ao nível do solo, ao longo do ciclo de vida da planta. Na porção proximal da raiz ocorre auto-enxertia da base dos ramos por ela emitidos. A raiz acumula lipídios e frutanos, apresenta ligeira contração e forma gemas reparativas; a formação das gemas adventícias se dá a partir do periciclo proliferado. Tais características poderiam ser associadas ao processo de adaptação da espécie às condições do Cerrado.Several native herbaceous and subshrub species native to the Cerrado in Brazil are geophytes, that is, they survive the unfavorable dry season and low temperatures, that sometimes coincide with fire, with only the underground system intact. Vernonia oxylepis is one of these species and the aim of this study was to describe the morpho-anatomy of the tuberous root and bud formation on this structure. The main axis of this root is perpendicular to the soil surface, and from which aerial shoots arise periodically throughout the life cycle. On the upper portion of the root, self-grafting of the shoots occurs. The root stores lipids and fructans, exhibits contraction and produces reparatory buds; adventitious buds arise from proliferated pericycle. These characteristics may be related to adaptation of this species to conditions in the Cerrado.

As plantas esciófitas são maiores e apresentam um período de floração em torno de 120 dias, enquanto que as heliófitas são menores e florescem ao longo de todo o ano. A espécie apresenta atributos florais à ornitofilia, estando o volume (16,7 µL ± 4 e concentração (27,25% do néctar produzido pelas flores dentro do esperado para espécies polinizadas por beija-flores. A freqüente visitação de Amazilia fimbriata, Thalurania glaucopis e Thalurania sp. (Trochilidae confirma esta observação, porém abelhas e borboletas também foram consideradas potenciais polinizadores, sugerindo co-evolução de síndromes florais secundárias. Baseando-se nos resultados dos testes de polinizações manuais e no desenvolvimento dos tubos polínicos, pode-se concluir que a espécie não apresenta auto-incompatibilidade, formando frutos com sementes férteis, com germinação superior a 80%, oriundas tanto de fecundação cruzada quanto da autopolinização. A população heliófita apresentou elevadas taxas de partenocarpia (52, 95% e mostrou ser um método seguro e eficaz de se avaliar a fertilização das flores, podendo-se assim, relacionar a sua freqüência e abundância à ausência ou ineficiência dos visitantes florais. Os frutos e sementes foram dispersos por pássaros das famílias Thraupidae e Pipridae e predados por lagartas da borboleta Tecla sp.

The shade tolerant plants are bigger and present a flowering period of around 120 days, while the heliophytic plants are smaller and blossom throughout all year. The species presents ornithophilous floral attributes, being the volume (16,7 µL ± 4 and concentration (27,25% of the nectar produced by the flowers characteristic of a hummingbird pollinated flower. The frequent visitation of Amazilia fimbriata, Thalurania glaucopis and Thalurania sp.

Based on the results of manual pollination tests and on the development of the polinic tubes, can be concluded that the species does not present self-incompatibility, forming fruits with fertile seeds, with a germination rate higher than 80%, both in cross-pollination as well as in selfing tests. The heliophytic population presented a high rate of parthenocarpy (52, 95% and showed to be a safe and efficient method to evaluate the fertilization of the flowers, being possible to relate the frequency and abundance of parthenocarpy to the absence or inefficiency of the pollinators. The fruits and seeds were dispersed by birds of the families Thraupidae and Pipridae and predated by larva of the butterfly Tecla sp. (Lycaenidae.

    Full Text Available Vanillosmopsis Sch. Bip. tem sido, tradicionalmente, aceito como sinônimo de Eremanthus Less. e o gênero Albertinia Spreng. foi estabelecido para abrigar Albertinia brasiliensis Spreng. O presente trabalho propõe a caracterização polínica de Albertinia brasiliensis, Vanillosmopsis erythropappa e Eremanthus bicolor e fornece subsídios para futuros estudos taxonômicos. Foram utilizados grãos de pólen de espécimens coletados em diferentes herbários. As duas primeiras espécies são encontradas no Rio de Janeiro enquanto Eremanthus Less. não. Assim, optou-se por utilizar a espécie-tipo do gênero na análise polínica. Os grãos de pólen foram acetolisados, medidos, descritos e ilustrados usando microscopia de luz. Grãos de pólen não acetolisados foram usados para análise em microscopia eletrônica de varredura. O resultado do estudo polínico mostrou que as espécies podem ser separadas utilizandose, principalmente, as características das aberturas e da ornamentação da exina e revelou uma gradação evolutiva interespecífica dos caracteres polínicos. Com relação à taxonomia das espécies estudadas, os dados palinológicos comprovam a posição taxonômica de Albertinia brasiliensis, porém não reforça a sinonimização de Vanillosmopsis em Eremanthus.Vanillosmopsis Sch. Bip. has been traditionally accepted as a synonym of Eremanthus Less., and Albertinia Spreng. was established to include Albertinia brasiliensis Spreng. This paper characterizes the pollen of Albertinia brasiliensis, Vanillosmopsis erythropappa and Eremanthus bicolor and provides information for future taxonomic studies. Pollen grains of specimens collected in different herbaria were used in this study. The two first species are found in Rio de Janeiro, but Eremanthus is not found in this state. For this reason, the type species of this genus was used for pollen analysis. Pollen grains were acetolysed, measured, described and illustrated using optical microscopy. Non-acetolysed pollen grains were used for analysis in scanning electron microscopy. The results showed that these species can be distinguished using mainly exine ornamentation and aperture features, revealing an interspecific evolutionary gradation of pollen characteristics. As regards the taxonomy of the species studied, the palynological data confirm the taxonomic position of Albertinia brasiliensis, but they do not support the subordination of Vanillosmopsis to Eremanthus.

    Occupational exposures are thought to be responsible for 10-15% of new-onset asthma cases in adults, with disparities across sectors. Because most of the data are derived from registries and cross-sectional studies, little is known about incidence of occupational asthma (OA) during the first years after inception of exposure. This paper describes the design of a study that focuses on this early asthma onset period among young workers in the bakery, pastry making and hairdressing sectors in order to assess early incidence of OA in these "at risk" occupations according to exposure duration, and to identify risk factors of OA incidence. The study population is composed of subjects who graduated between 2001 and 2006 in these sectors where they experience exposure to organic or inorganic allergenic or irritant compounds (with an objective of 150 subjects by year) and 250 young workers with no specific occupational exposure. A phone interview focusing on respiratory and 'Ear-Nose-Throat' (ENT) work-related symptoms screen subjects considered as "possibly OA cases". Subjects are invited to participate in a medical visit to complete clinical and lung function investigations, including fractional exhaled nitric oxide (FENO) and carbon monoxide (CO) measurements, and to collect blood samples for IgE (Immunoglobulin E) measurements (total IgE and IgE for work-related and common allergens). Markers of oxidative stress and genetic polymorphisms exploration are also assessed. A random sample of 200 "non-cases" (controls) is also visited, following a nested case-control design. This study may allow to describ a latent period between inception of exposure and the rise of the prevalence of asthma symptoms, an information that would be useful for the prevention of OA. Such a time frame would be suited for conducting screening campaigns of this emergent asthma at a stage when occupational hygiene measures and adapted therapeutic interventions might be effective.

  19. Analysis of the Involvement of Different Ceramide Variants in the Response to Hydroxyurea Stress in Baker's Yeast.

    Directory of Open Access Journals (Sweden)

    Po-Wei Chen

    Full Text Available Sphingolipids have been identified as important signaling compounds in stress responses. However, it is not always clear how different sphingolipid profiles are achieved in a particular stress situation. Here we propose a detailed mass action model, containing 42 dependent variables and 137 reactions, that offers explanations of the roles of variant ceramides species, which differ in the lengths of their fatty acyl chains and their saturation state, in the response to hydroxyurea stress. The simulations demonstrate that the cells manage to achieve hydroxyurea tolerance through a well-coordinated, differential usage of the variant ceramide species. Moreover, the results suggest that key enzymes have different affinities toward saturated and unsaturated fatty acyl chains, which implies that the saturation state affords the cells with an additional mode of regulation that had not been recognized so far. These conclusions from our computational analysis are yet to be validated experimentally.

    Efficient in vitro propagation systems via organogenesis and synthetic seeds were developed for the first time for conservation and commercial propagation from leaf or longitudinal thin cell layer (lTCL) leaf or shoot-tip explants of Urginea altissima . Various plant growth regulators and phloroglucinol were used in semi-solid and liquid Murashige and Skoog (MS) medium to establish multiplication of shoots and roots for in vitro regeneration. Of the various treatments, the highest number of shoots (17.4 per lTCL leaf explant) was obtained on liquid MS medium supplemented with 10 µM meta -Topolin ( m T) and 2 µM benzyladenine followed by transferal to semi-solid MS media. The shoot tips were encapsulated with liquid MS medium plus 3% (w/v) sodium alginate and 100 mM calcium chloride. Adventitious shoot regeneration (91.0%; 12.6 shoots per synthetic seed) of synthetic seeds was achieved on semi-solid MS medium supplemented with 10 µM m T and 2 µM naphthaleneacetic acid (NAA) after 15 days of storage in darkness at 25 ± 2 °C. Regenerated shoots rooted (9.8 roots per shoot; 6.5 cm long) efficiently when transferred to 5 µM indole-3-butyric acid and 2.5 µM NAA. All the plantlets were successfully acclimatized (100%) in a vermiculite:soil (1:1 v/v) mixture in the greenhouse.

    In this study, simultaneous degradation of organic matter and color removal from food processing industries wastewater using an integrated anaerobic baffled reactor granular activated carbon (IABRGAC) was investigated. Theretofore, effective parameters such as hydraulic retention time (HRT) and granular activated carbon (GAC) filling ratio were studied. The bioreactor was operated at 3, 4 and 5 d of HRT and GAC filling ratio of 20%, 35% and 50%. To analyze and optimize the independent operating variables, response surface methodology was applied. Operating condition was optimized for HRT (4 d) and GAC filling ratio (50%). Better COD (94.6%) and BOD (93.7%) removal efficiency occurred with loading COD of 15,000 mg/L, with diminished wastewater color around 54% and turbidity to 54 NTU. In addition, methane production, methane yielding rate (Y m ) and specific methanogenic activity (SMA) test in an integrated system were investigated. The system IABRGAC was able to generate a volumetric rate about 0.31 and 0.44 L/g COD removed d at the experimental condition. The Y m was between 0.31 and 0.44 L/g COD removed .d and SMA was between 0.13 and 0.38 g COD/g volatile suspended solid. Based on results it can be concluded that the IABRGAC to be a successful pretreatment for highstrength wastewater before discharging the final effluent to sewerage and aerobic treating processes.

    Tetranychus evansi (Te) is an exotic pest of solanaceous crops in Africa. The predatory mite Phytoseiulus longipes (Pl) and the fungus Metarhizium anisopliae (Ma), are potential biocontrol agents of Te. The present study investigated efficacy of fungus-treated foam placed above or below the third Te-infested tomato leaf. The persistence of fungus-treated foam and the performance of Pl with or without fungus-treated foam were evaluated. The fungus-treated foam was effective when Te infestation was below the third tomato leaf as no damage was recorded on all upper tomato leaves up to 30 days post-treatment. However, in the control treatments, the infestation increased considerably from 9±0.3% to 100±0% at 15 days post-treatment. The reuse of the fungus-treated foam at 15, 30 and 45 days post-treatment resulted in 19±1.4%, 25±1.2% and 54±2.1% respective infestation by Te. The fungus-treated foam and Pl alone are efficient, but there is no benefit to combinting both against Te. The fungus-treated foam is an effective method to optimize the use of Ma in screenhouse conditions. These two control agents could be integrated in an IPM strategy for crops protection. However, these results need to be confirmed in large field trials. This article is protected by copyright. All rights reserved. This article is protected by copyright. All rights reserved.

    Full Text Available The chemical composition of the essential oils from aerial parts of Pectis apodocephala and Pectis oligocephala were analyzed by GC-MS. The essential oils of these species were predominantly constituted by monoterpenes. Geranial (42.9-44.5%, neral (32.2-34.2% and alpha-pinene (10.7-11.4% were the main constituents in the oil of P. apodocephala, while p-cymene (50.3-70.9% and thymol (24.4-44.7%, were the prevalent compounds in the oil of P. oligocephala. The essential oils were tested against the root knot nematode Meloidogyne incognita and Aedes aegypti larvae survival. The results obtained show that both essential oils exhibited significant activity and could be considered as potent natural namaticidal and larvicidal agents.A composição química dos óleos essenciais das partes aéreas de Pectis apodocephala e Pectis oligocephala foi analisada por CG-EM.

    Lesser degrees of terminal duct lobular unit (TDLU) involution, as reflected by higher numbers of TDLUs and acini/TDLU, are associated with elevated breast cancer risk. In rodent models, the insulin-like growth factor (IGF) system regulates involution of the mammary gland. We examined associations of circulating IGF measures with TDLU involution in normal breast tissues among women without precancerous lesions. Among 715 Caucasian and 283 African American (AA) women who donated normal breast tissue samples to the Komen Tissue Bank between 2009 and 2012 (75% premenopausal), serum concentrations of IGF-I and binding protein (IGFBP)-3 were quantified using enzyme-linked immunosorbent assay. Hematoxilyn and eosin-stained tissue sections were assessed for numbers of TDLUs ("TDLU count"). Zero-inflated Poisson regression models with a robust variance estimator were used to estimate relative risks (RRs) for association of IGF measures (tertiles) with TDLU count by race and menopausal status, adjusting for potential confounders. AA (vs. Caucasian) women had higher age-adjusted mean levels of serum IGF-I (137 vs. 131 ng/mL, p = 0.07) and lower levels of IGFBP-3 (4165 vs. 4684 ng/mL, p IGF-I:IGFBP-3 ratios were associated with higher TDLU count in Caucasian (RR T3vs.T1 =1.33, 95% CI = 1.02-1.75, p-trend = 0.04), but not in AA (RR T3vs.T1 =0.65, 95% CI = 0.42-1.00, p-trend = 0.05), women. Our data suggest a role of the IGF system, particularly IGFBP-3, in TDLU involution of the normal breast, a breast cancer risk factor, among Caucasian and AA women. © 2018 UICC.

After 8 h of starvation, the content of trehalose and glycogen was increased 4-fold and 2-fold, respectively. Carbon starvation resulted in a partial conversion of glycogen into trehalose. The trehalose content...... increased from 45 to 64 mg (g dry-weight)(-1), whereas the glycogen content in the same period was reduced from 55 to 5 mg (g dry-weight)(-1). Glycogen was consumed faster than trehalose during storage of the starved yeast for 1 month. Nitrogen starvation resulted in a decrease in the protein content...

    Overproduction of a desired metabolite is often achieved via manipulation of the pathway directly leading to the product or through engineering of distant nodes within the metabolic network. Empirical examples illustrating the combined effect of these local and global strategies have been so far limited in eukaryotic systems. In this study, we compared the effects of overexpressing a key gene in de novo vanillin biosynthesis (coding for O-methyltransferase, hsOMT) in two yeast strains, with and without model-guided global network modifications. Overexpression of hsOMT resulted in increased vanillin production only in the strain with model-guided modifications, exemplifying advantage of using a global strategy prior to local pathway manipulation.

    The response of Saccharomyces cerevisiae and freeze-tolerant Torulaspora delbrueckii strains to osmotic stress and their CO2 production capacity in sweet and frozen-sweet dough has been examined. T. delbrueckii strains, IGC5321 and IGC5323 showed higher leavening ability than Saccharomyces, specially after exposure to hyperosmotic stress of bread dough containing 20% sucrose and 2% salt added. In addition, Torulaspora and especially T. delbrueckii IGC5321 exhibited no loss of CO2 production capacity during freeze-thaw stress. Overall, these results appeared to indicate that Torulaspora cells are more tolerant than Saccharomyces to osmotic stress of bread dough. This trait correlated with a low invertase activity, a slow rate of trehalose mobilisation and the ability to respond rapidly to osmotic stress. Growth behaviour on high osmotic synthetic media was also examined. Cells of the IGC5321 strain showed intrinsic osmotolerance and ion toxicity resistance. However, T. delbrueckii IGC5323 exhibited a clear phenotype of osmosensitivity. Hence, this characteristic may not be essential or the only determinant for leavening ability in salted high-sugar dough.

    Here, we present a novel approach to form hydrogels from yeast whole cell protein. Countless hydrogels are available for sophisticated research, but their fabrication is often difficult to reproduce, with the gels being complicated to handle or simply too expensive. The yeast hydrogels presented here are polymerized using a four-armed, amine reactive crosslinker and show a high chemical and thermal resistance. The free water content was determined by measuring swelling ratios for different protein concentrations, and in a freeze-drying approach, pore sizes of up to 100 μm in the gel could be created without destabilizing the 3D network. Elasticity was proofed to be adjustable with the help of atomic force microscopy by merely changing the amount of used protein. Furthermore, the material was tested for possible cell culture applications; diffusion rates in the network are high enough for sufficient supply of human breast cancer cells and adenocarcinomic human alveolar basal epithelial cells with nutrition, and cells showed high viabilities when tested for compatibility with the material. Furthermore, hydrogels could be functionalized with RGD peptide and the optimal concentration for sufficient cell adhesion was determined to be 150 μM. Given that yeast protein is one of the cheapest and easiest available protein sources and that hydrogels are extremely easy to handle, the developed material has highly promising potential for both sophisticated cell culture techniques as well as for larger scale industrial applications.

    Full Text Available The effects of an aqueous extract of the leaves of Sansevieria senegambica on plasma marker enzymes, plasma chemistry and the haematological profile of salt-loaded rats were studied. The control group received only a commercial feed, whilst the four test groups received a diet consisting of the commercial feed and salt, although the reference treatment group was reverted to the normal feed at the end of 6 weeks. The extract was orally administered daily at 150 mg/kg or 200 mg/kg body weight to two test groups, respectively; whilst the test control, reference and control groups received equivalent volumes of water by the same route. The extract had no negative effects on markers of liver and kidney functions, but it did produce leukocytosis, significantly increased (p < 0.05 plasma calcium and potassium levels and significantly decreased (p < 0.05 plasma sodium and chloride levels in the test animals compared to the test control animals. This result supports the traditional use of Sansevieria senegambica in the management of hypertension, whilst suggesting that the extract may be a potassium-sparing diuretic whose mechanism of antihypertensive action may be achieved through alteration of plasma sodium and potassium balances, or through calcium-mediated changes in vascular muscle tone.

    Full Text Available Farmers in Kenya continue to raise concerns of difficulty in managing Tetranychus evansi, the most widespread pest species of tomato applying the most commonly used acaricides. This invasive pest species is not only found in Kenya, but in Eastern and Southern Africa, as well as parts of Europe and Asia. In the current study, populations of T. evansi were collected from farms in the four major tomato-growing areas of Kenya (Loitoktok, Kibwezi, Athi-River and Subukia and their susceptibility compared to a laboratory culture (ICIPE that had been maintained for three years without exposure to acaricides. Susceptibility of T. evansi eggs and adults (contact and residual to Brigade (bifenthrin, Dimethoate (dimethoate, Karate (lambdacyhalothrin, Kelthane (dicofol, Omite (propargite and Polytrin (profenofos+ cypermethrin was tested in the laboratory using respective manufacturer’s recommended concentrations. Dimethoate resulted in variable ovicidal mortality while Kelthane, Brigade, Karate, Omite and Polytrin had high mortality across all populations. Similarly, adult contact and residual mortality was lower than that of the other chemicals when exposed to Dimethoate regardless of the location. Furthermore, it also had no residual effect on the mites from ICIPE and Kibwezi. On the other hand, Kelthane was most lethal against the mites from all locations followed by Brigade and Polytrin in that order. Omite caused significantly lower mortality on mites from Subukia while Karate produced variable effects on mites from Kibwezi, Loitoktok and Subukia. The implications of these findings are further discussed.

    Inhabitants of the Eastern Cape Province of South Africa use the roots of Dianthus thunbergii and corms of Hypoxis argentea to treat diabetes mellitus and other ailments. The objective of this study was to analyze the phytochemical composition and antioxidant activities of the aqueous and ethanol extracts of the roots and corms of two plants. Total phenolics, flavonoids, flavonols, proanthocyanidins, tannins, and alkaloids were determined by standard methods. The scavenging activities of the extracts against 1,1 diphenyl-2-picrylhydrazyl (DPPH), 2'-azino-bis (3-ethylbenthiazoline-6-sulfonic acid (ABTS), nitric oxide (NO), hydrogen peroxide (H 2 O 2 ), and their ferric-reducing antioxidant potentials (FRAPs) were measured. The ethanol extract of H. argentea had the highest content of phenolics (66.71 ± 2.71 mg gallic acid equivalent/g) and tannins (1.18 ± 0.07 mg TAE/g), while the ethanol extract of D. thunbergii gave higher contents of flavonoids and proanthocyanidins (62.21 ± 1.75 mg Qe/g and 432.62 ± 2.43 mg Ca/g, respectively). Flavonols were the most predominant in the aqueous extract of H. argentea (25.51 ± 1.92 mg Qe/g). We observed a concentration-dependent response in the ABTS- and H 2 O 2 -scavenging activities and FRAP values of the extracts and standards (Vitamin C, butylated hydroxytoluene, and rutin). The ethanol extracts of both plants generally demonstrated better antioxidant activities against H 2 O 2 , NO, and ABTS while also possessing better reducing power than the aqueous extracts. The aqueous extract of D. thunbergii , however, showed the best DPPH scavenging activity. The higher content of phytochemicals and antioxidant capacity obtained for the ethanol extracts of D. thunbergii and H. argentea may prove to be valuable information in selecting suitable extraction solvents for the medicinal applications of both plants. Ethanol extracts of Hypoxis argentea had the highest levels of phenolics and tanninsEthanol extracts of Dianthus thunbergii had the highest levels of flavonoids and proanthocyanidinsEthanol extracts of both plants possess better antioxidant activityagainst hydrogen peroxide, nitric oxide, and ABTS as well as higher reducingpower than the aqueous extractsAqueous extract of Dianthus thunbergii had the highest free radical scavenging activity as measured with DPPH.

    Metals are components of the biosphere, occurring naturally in soil and plants, but as a result of human actions, their levels have been greatly increased, depending on the region. Copper (Cu) and zinc (Zn) are essential for the growth and development of plants, however if in excess become toxic. The aim of this study was to evaluate the potential of plants to absorb Cu and Zn and what effects they cause in seedlings cultivated in vitro. The results of this study may contribute primarily in agricultural and environmental research. The plant investigated was the Aechmea blanchetiana species of the Bromeliaceae family. It is a terrestrial or epiphytic species used as an ornamental plant. The cultivation of seedlings for this study and their exposure to different concentrations of Cu and Zn were performed at the Institute of Botany (IBt) of Sao Paulo. After seed germination, the seedlings were transferred for growth in a culture media containing different concentrations of Cu or Zn. After this period of in vitro cultivation, the seedlings were analyzed for morphometry, anatomy and by neutron activation analysis. Quality control of the results from neutron activation analysis was carried out by the analysis of certified reference materials. The data obtained showed good precision and accuracy for several elements determined. The highest concentrations of Cu used in the exposure were those that caused major structural changes in morphometric and anatomical parameters, however for the Zn no significant differences were verified for most parameters. The A. blanchetiana proved to be a bioaccumulator species of Zn, absorbing high levels of this element in the aerial parts and roots. (author)

    Several studies have reported biological effects of Mikania glomerata and Mikania laevigata, used in Brazilian folk medicine for respiratory diseases. Pneumoconiosis is characterized by pulmonary inflammation caused by coal dust exposure. In this work, we evaluated the effect of pretreatment with M. glomerata and M. laevigata extracts (MGE and MLE, respectively) (100 mg/kg, s.c.) on inflammatory and oxidative stress parameters in lung of rats subjected to a single coal dust intratracheal instillation. Rats were pretreated for 2 weeks with saline solution, MGE, or MLE. On day 15, the animals were anesthetized, and gross mineral coal dust or saline solutions were administered directly in the lung by intratracheal instillation. Fifteen days after coal dust instillation, the animals were killed. Bronchoalveolar lavage (BAL) was obtained; total cell count and lactate dehydrogenase (LDH) activity were determined. In the lung, myeloperoxidase activity, thiobarbituric acid-reactive substances (TBARS) level, and protein carbonyl and sulfhydryl contents were evaluated. In BAL of treated animals, we verified an increased total cell count and LDH activity. MGE and MLE prevented the increase in cell count, but only MLE prevented the increase in LDH. Myeloperoxidase and TBARS levels were not affected, protein carbonylation was increased, and the protein thiol levels were decreased by acute coal dust intratracheal administration. The findings also suggest that both extracts present an important protective effect on the oxidation of thiol groups. Moreover, pretreatment with MGE and MLE also diminished lung inflammatory infiltration induced by coal dust, as assessed by histopathologic analyses.

    The identity of one species of Iris (Iridaceae) from Locality at Shafa Badran area in Amman/Jordan has been reassessed and reidentified as I.nigricans Dinsmore, the national flower of Jordan, as it is misidentified as I. atrofusca for plants collected and identified from this area previously and as recorded in the related literature ( Post, 1932; Feinbrun, 1986). This decision has been made on the basis of studying fresh plants collected from Shafa Badran area, northeast of Amman in the period March-April 2001. The confirmation of identity of the species of Iris occur in Shafa Badran was based on studying the morphological characteristics of the leaves ,stems flowers for plants collected from that area, as well as studying the pollen grains and seed characteristics using light and scanning electron microscopy, as compared with plants of Iris nigricans collected from Madaba area for the same characters. Moreover, herbarium specimens deposited st Amman herbarium were checked and reidentified as I. nigricans. The results of studying the vegetative reproductive characters suggesting that the species that is occurring in Shafa Badran area is I.nigricans. However, these findings suggest that an interbreeding might have taken place between the individuals of I. nigricans in Shafa Badran and I.atrofusca from a neighboring geographical area called Jarash in North of Jordan, close enough that they are not geographically isolated for specimens that were probably intermixed with the population of Iris nigricans in Shafa Badran area.

In this study, we compared the effects of overexpressing a key gene in de novo vanillin biosynthesis (coding for O‐methyltransferase, hsOMT) in two yeast strains, with and without model‐guided global network modifications. Overexpression of hsOMT resulted in increased...... vanillin production only in the strain with model‐guided modifications, exemplifying advantage of using a global strategy prior to local pathway manipulation.

    Full Text Available Ananas ananassoides é uma planta perene com hábito de crescimento herbáceo e que tem enorme potencial paisagístico porque apresenta flores e brácteas com coloração exuberante e folhas com margens espinescentes que estão distribuídas em roseta. O objetivo deste experimento foi o de avaliar as características germinativas e o efeito de tratamentos pré-germinativos nas sementes da espécie. Primeiro, em um delineamento inteiramente casualizado, foram investigados seis tratamentos em quatro repetições de 25 sementes. Os tratamentos constaram da imersão em água destilada à temperatura ambiente (25 ± 1,5°C durante 24, 48 e 72h, imersão em água quente a 90°C durante 2 min. e imersão em ácido sulfúrico p.a. durante 2 min. e com posterior lavagem em água corrente por 24h que foram comparados com um controle. Depois de quatro meses de armazenamento, sementes intactas (controle foram comparadas com sementes imersas em água a 90°C por 2 min. Assim, a maior porcentagem de germinação (92% foi obtida com sementes recém-colhidas e imersas em água a 90°C durante 2 min., mas o armazenamento por quatro meses melhorou a porcentagem de germinação (G ≥ 96,0%. Os tempos médios de germinação não diferiram entre as sementes recém-colhidas (de 21,0 a 26,8 dias e as armazenadas (entre 18,4 e 19,5 dias. A germinação das sementes recém-colhidas e armazenadas foi lenta e distribuída ao longo do tempo experimental.Ananas ananassoides is a perennial plant with ornamental potential because of flowers and bracts with exuberant colors and herbaceous development where the leaves have spiny margins that are distributed in rosettes. The objective of this experiment with six completely randomized treatments and four replicates of 25 seeds was to evaluate the effects of seed soaking into distilled water at environmental temperature (25 ± 1.5°C for 24, 48, and 72h; seed soaking into water at 90°C for 2 minutes; seed soaking into sulfuric acid p.a. for 2 minutes followed by tap water washing for 24h, and the control. Thereafter, 4-month-old seeds were immersed into water at 90°C for 2 minutes and compared to the intact seeds (control. Initially, the highest percentage of germination (G=92% was evaluated in newly collected seeds that were immersed in water at 90°C for 2 minutes. No increases in the percentage of seed germination were detected by seed soaking into water or sulfuric acid in comparison to the seeds that were immersed in water at 90°C for 2 minutes. However, the percentage of germination was higher than 96% when the seeds were stored for four months. No difference in the mean time to germination was detected between newly collected (between 21.0 and 26.8 days and stored seeds (between 18.4 and 19.5 days. The germination of newly collected and stored seeds was slow and distributed throughout the experimental time.

    Metals are components of the biosphere, occurring naturally in soil and plants, but as a result of human actions, their levels have been greatly increased, depending on the region. Copper (Cu) and zinc (Zn) are essential for the growth and development of plants, however if in excess become toxic. The aim of this study was to evaluate the potential of plants to absorb Cu and Zn and what effects they cause in seedlings cultivated in vitro. The results of this study may contribute primarily in agricultural and environmental research. The plant investigated was the Aechmea blanchetiana species of the Bromeliaceae family. It is a terrestrial or epiphytic species used as an ornamental plant. The cultivation of seedlings for this study and their exposure to different concentrations of Cu and Zn were performed at the Institute of Botany (IBt) of Sao Paulo. After seed germination, the seedlings were transferred for growth in a culture media containing different concentrations of Cu or Zn. After this period of in vitro cultivation, the seedlings were analyzed for morphometry, anatomy and by neutron activation analysis. Quality control of the results from neutron activation analysis was carried out by the analysis of certified reference materials. The data obtained showed good precision and accuracy for several elements determined. The highest concentrations of Cu used in the exposure were those that caused major structural changes in morphometric and anatomical parameters, however for the Zn no significant differences were verified for most parameters. The A. blanchetiana proved to be a bioaccumulator species of Zn, absorbing high levels of this element in the aerial parts and roots. (author)

    Full Text Available Guaco (Mikania laevigata is a medicinal plant used to treat fever, rheumatism, flu and respiratory tract diseases. Understanding the physiology of this species and its responses to environmental conditions has become necessary to improving the cultivation methods. In this context, this work aimed to access the effects of shading by using colored nets in on photosynthetic pigment concentration, photosynthetic rate and ultrastructure of chloroplasts of Mikania laevigata. The plants were cultivated during four months under nets with 50% shading in blue, red and gray color nets and under full sunlight (0%. The plants grown under full sunlight had decreased contents of a and b chlorophyll, and of carotenoids, while those grown under blue nets shown higher concentrations of a and b chlorophyll. The lowest density of chloroplasts was found in plants cultivated under full sunlight. Elongated chloroplasts were noticed in treatments with 50% shading. Regarding the potential rate of photosynthesis no significant change was observed among the plants grown under red, blue and gray nets, which leads to the conclusion that the spectrum transmitted by different coloured nets did not affect guaco photosynthetic apparatus.O guaco (Mikania laevigata é uma planta medicinal, usada para o tratamento de febre, reumatismo, gripe e doenças do trato respiratório. O entendimento do comportamento fisiológico dessa espécie e as suas respostas às condições do ambiente tornam-se necessários ao aperfeiçoamento dos métodos de cultivo. Nesse contexto, o presente trabalho teve como objetivo avaliar os efeitos do sombreamento com uso de malhas coloridas na concentração de pigmentos fotossintéticos, na taxa de fotossíntese e na ultra-estrutura de cloroplastos de plantas de Mikania laevigata. As plantas foram cultivadas por quatro meses sob malhas de 50% de sombreamento nas cores azul, vermelha e cinza e a pleno sol (0%. As plantas mantidas a pleno sol tiveram os menores teores de clorofila a e b e o menor teor de carotenóides, enquanto aquelas cultivadas sob malha azul tiveram a maior concentração de clorofilas a e b. A menor densidade de cloroplastos foi encontrada nas plantas cultivadas a pleno sol. Nos tratamentos com 50% de sombreamento, foram verificados cloroplastos mais alongados. Com relação à taxa de fotossíntese potencial, não foi observada nenhuma diferença significativa entre plantas crescidas sob as malhas vermelha, cinza e azul, fato que leva a acreditar que o espectro diferenciado transmitido pelas malhas coloridas não interferiu no aparelho fotossintético do guaco.

We tested the hypothesis that acute ingestion of NaHCO3– would increase blood lactate concentrations [BLa], enhance performance, and reduce rating of perceived exertion (RPE in the Yo-Yo IR1. Eight recreationally active males (N=8, age: 26±4 yr, height: 178±6 cm, body mass: 82±10 kg participated in the Yo-Yo IR1 on two separate occasions, separated by 1 wk, in a randomized crossover design. Following familiarization, during seated rest, participants’ pretest [BLa] was taken, and participants then consumed either a placebo of 0.3 g·kg–1 body weight sodium chloride or 0.3 g·kg–1 body weight NaHCO3–. Sixty minutes postingestion, a standardized warm-up preceded the Yo-Yo IR1. Upon completion, postexercise [BLa] (mmol·L–1, RPE (arbitrary units and Yo-Yo IR1 time to fatigue (s were recorded. Paired t-test revealed a small but significant improvement in Yo-Yo IR1 performance under the NaHCO3– condition (610±267 sec, compared to the placebo condition (556±259 sec; p=0.01; Cohen’s d=0.20. [BLa] increased more under the NaHCO3– condition (1.6±0.7 to 17.5±5.2 mmol·L–1; p<0.001; Cohen’s d=4.29, compared to the placebo condition (2.0±0.7 to 11.5±5.0 mmol·L–1; p=0.001; Cohen’s d=2.66. Postexercise RPE was not significantly different between conditions. The results of this study suggest that acute NaHCO3– ingestion improves Yo-Yo IR1 performance without altering RPE, likely

    Full Text Available Objective – To determine whether it is cost effective to staff an academic reference desk with librarians through an examination of the types of reference questions being asked and the qualifications required to answer them.Design – Content analysis of reference transaction logs and activity-based costing for reference services based on quantitative data derived from the logs.Setting – Stetson University, a private institution in the United States with an FTE of approximately 2500.Subjects – 6959 phone, email, and in-person reference transactions logged at the reference desk by four full-time and two part-time librarians.Methods – This study repurposes data originally collected to determine the frequency with which librarians turned to online versus print sources when responding to questions at the reference desk. Librarians working at the Stetson University library reference desk recorded all reference queries received in person, by phone, or by email for a total of eight months between 2002 and 2006. Data collection took place in two month intervals in fall 2002, spring 2003, spring 2006, and fall 2006. Each question and the sources used to address it were logged by the librarian. Directional questions that were not related to the library’s collections and technical questions dealing with printer or copier mechanical problems were counted, but the specifics of these questions were not recorded. It was felt that these queries would not yield data relevant to the original research question on sources used as they “did not directly relate to an information need” (391. A total of 6959 questions were logged by librarians during the four collection periods. Questions were recorded for only 4431 transactions; the remaining 2528 queries related to printer/copier problems or non-library specific directions and were described as “direction and machine: non- informational” (394. The 4431 recorded questions were then divided into four categories derived by the researcher: look-up (a search for a known item, directional (library-specific orientation to the space and collections, technology (assistance with using library technology and electronic resources, and reference. The category of reference was further subdivided into eight additional categories: catalogue search, citation help, database help, “guide to correct databases,” “personal knowledge or referral,” “quick internet search,” research, and Serials Solutions (392. “Guide to correct databases” referred to advice on the appropriate database to answer a question and serials solutions included questions that could be answered using the Serials Solutions product, such as the availability of a particular journal or article in the collection (392. Questions were assigned to the single most appropriate category by the researcher. Question categories were then mapped to “suggested staffing levels” (396. This determination was made by the researcher, and no details were given as to how the decision was made for each category. The three levels of staffing discussed were librarian, “trained student or staff,” and “well-trained staff/occasional librarian referral” (396. The cost of staffing the reference desk during the eight months captured in this study was calculated by multiplying the hours worked by each librarian by his/her individual average rate of pay across the four data collection periods. Indirect staff costs such as benefits were not included in this calculation. The average cost per reference transaction was determined by dividing the total salary costs by the total number of reference queries during the periods of study. Costs for those categories of questions best addressed by a librarian could then be determined. The actual number of librarians who participated in the study is unclear. The methodology refers to four full-time and two part-time librarians (391. However, later in the article there is reference to five full-time and three part-time librarians rather than the numbers initially stated (396. This may reflect staffing changes during the study period, with the first set of numbers referring to positions rather than individuals, but this cannot be verified with the evidence presented in the article.Main Results – It was determined that most questions asked at the reference desk during the study period could have been addressed by trained student and staff member rather than librarians. Only 11% (784 of questions logged were deemed sufficiently complex by the researcher to require the attention of a librarian. The remaining 6175 transactions (89% of all those logged could most likely be handled by a different staffing complement. According to Ryan, approximately 74% of the reference transactions, including directional, technology, “quick internet,” and known item searching questions could have been answered by “trained student and staff” (396. Questions on catalogue searching, databases, citations, Serial Solutions, and personal knowledge/referrals, representing approximately 15% of all questions, could have been handled by experienced and knowledgeable staff with limited librarian intervention. The complexity of the question was in part judged by the number of sources required to answer it, with most (75% answerable with just one source. The total cost of staffing the reference desk with librarians for the eight months studied was approximately US$49,328.00. A total of 6959 questions were logged during this period, resulting in an average cost of US$7.09 per reference transaction. This cost is approximate, as the exact time spent on each question was not recorded. The cost of answering “non-informational” directional and technical questions was the most significant (396. This category represented 36.3% of all questions received at the reference desk, with a total staffing cost of $17, 919.41 ($7.09 x 2528. “Information-orientated” directional and technology questions followed at 15.4% (US$7,620 and 12.4% (US$6,110.18 respectively (396. According to Ryan, questions in all three categories could be addressed by students and staff. The cost of addressing research questions, the only category requiring librarians, was US$5557.29. Research transactions were greatly outnumbered by directional and technology related questions. An average of 3.6 research questions were asked at the reference desk during the 12 hours it was open each day, compared to 20.8 directional/technical questions.Conclusion – The nature of questions logged at the Stetson University library reference desk suggests that it is inefficient to staff the desk with librarians, given the salary costs of such a staffing model and the fact that librarian’s skills may not be required to answer most of the questions posed. Since the number of questions that need a librarian is so low, Ryan suggests that alternative staffing and service models be considered, so the energies of librarians could be more effectively employed elsewhere in the organization in areas such as information literacy instruction and the development of enhanced web services. It is noted that any reorganization of reference services should be done in concert with user surveys, consultation with staff, and extensive training to prepare staff for new roles. Suggested areas for further research identified by the researcher include the quality of reference transactions in an increasingly online environment.

    Full Text Available Objective – To investigate post-master’s educational needs and interests of information professionals.Design – Survey research using print and electronic questionnaires.Setting – The geographic area surrounding Wayne State University in Michigan, United States of America.Subjects – Members of the library associations of Michigan, Ohio, Indiana, and Southwestern Ontario, Canada.Methods – Systematic random samples were derived from the membership lists of the library associations in Ohio, Indiana, and Southwestern Ontario. Paper questionnaires were mailed to those selected. Michigan Library Association’s official policy barred the release of its membership list to researchers. Consequently, announcements of the survey were placed in three successive issues of the Association’s electronic newsletter. Interested members were directed to a website to complete an electronic version of the questionnaire. This option was also extended to members of the other three library associations. The overall research question was investigated through specific questions that sought to ascertain the overall level of interest in professional library and information studies (LIS education, levels of interest in specific types of programs, factors that favoured or deterred enrolment in doctoral programs, as well as the fields of study that were preferred for combination with LIS in doctoral programs. With the exception of demographic type questions (e.g., place of residence and educational qualifications and two questions that required open ended responses, the questionnaire design encompassed questions with Likert scale type responses. Analysis of the responses included descriptive statistics, the use of Pearson chi square to determine statistically significant relationships, and, to a lesser extent, content analysis.Main Results – A total of 270 questionnaires(33% were returned from three populations: Ohio, Indiana, and Ontario. A self-selected sample of 101 members (6% of the Michigan Library Association responded. In general, almost 80% of the respondents admitted some importance to adding to their LIS qualification. However, only 41% felt that this was important or extremely important. From a choice of six educational offerings, namely, continuing education activities, non-degree master’s coursework, a second master’s degree, post-master’s certification, doctoral programs, and other, continuing education activities was the most valued, by 65.5% of the respondents. Participants were asked about their reasons, and the importance of these, for considering or deciding to enrol in an LIS doctoral program. The yearning to acquire knowledge was reported by 69.7% as the major reason, followed by 45.8% of the respondents who cited the wish to increase their income potential. In terms of major factors, prestige received the lowest rating, 21.1%. The time involved (73.8%, cost(66.3%, and distance from the program (63.2% were cited as the major deterrents to enrolling in doctoral programs. When asked about the likelihood of pursuing a doctoral LIS program in combination with business administration, computer science, or without any combination, “not likely” was the most popular choice. Those who were very likely or likely to pursue a joint program totalled approximately 30% of the respondents, while 37% indicated an interest in undertaking a doctorate in LIS only. The most frequent reasons proffered by those who selected “not likely” or “definitely not” for any of the three doctoral offerings included lack of interest, mitigating factors (e.g. time, cost, age, and program location, unfavourable cost/benefit analysis, preference for another area of knowledge,and the view that Ph.D.s were only useful for university faculty. Given the option to name subject areas that they desired to see combined with LIS in a doctoral program, 23 of 101 respondents proposed education, while 19 opted for public administration. A question inviting any other comments on the issue of post-master’s education yielded a predominant desire for “non traditional instruction,” particularly online courses as well as classes held in convenient locations. In terms of relationships between geographic location and factors that influenced interest in enrolling in a doctoral program, the desire “to become a more effective manager,” and “other” were statistically significant. The analysis also revealed a strong positive relationship between willingness to pursue an LIS-only doctoral program and the availability of such a program in geographic proximity. Similarly, there was a strong relationship between willingness to pursue an LIS program in close vicinity and the importance that was given to further LIS education.Conclusion – Online instruction and geographic proximity are key determinants of information professionals’ interest in pursuing post-master’s education at the doctoral level. Continuing education activities, non-degree coursework, and certificate programs are preferred over doctoral LIS programs, despite the finding that the major reason for enrolling in doctoral LIS programs is to fulfill the desire for knowledge acquisition. Schools offering Library and Information Science studies need to explore options for providing distance-education doctoral LIS programs as a means of reversing the current shortage of LIS faculty.

    The objectives of this study were to evaluate effect of three dosages of ionizing radiation in combination with cold storage (0-2{sup 0} C), and the effect of cold storage without irradiation, establishing time curves for eclosion of eggs and mortality of juvenile and adult stages, and adult oviposture. An experimental Cs-137 Brookhaven Portable Cesium Development Irradiator (BPCDI N. 3) at the Chilean Nuclear Energy Commission, located in the La Reina Commune of Santiago, Chile, was used at dosages of 0.500, 1.000, and 1,500 Gy (with a dosage rate of 28.95 Gy/min), combined with pretreatment cold (0-2{sup 0} C) during 24 h, and 15 days of cold storage postirradiation, to simulate the duration of a grape shipment to the U.S., onto 1-4 and 1-4 and {>=} 4 day-old eggs, juveniles and adult stages. The initial stages of development were more susceptible to radiation when combined with cold storage. The mortality of both egg development stages, juveniles and adults, with dosages from 500-1.500; 1.000-1.500; and 1500 Gy, respectively, satisfied the probity 9 (99.9968%) quarantine security level requirement. The few survivors from treated juveniles and adults were unable to continue their cycle, and did not present quarantine risk. All dosages used produced 100% mortality. Apparently, cold storage has a synergic effect when used in combination with radiation. Cold storage of stages not irradiated somewhat the population dynamics. (author). 58 refs, 24 figs, 12 tabs.

  12. Thermoluminescent response of dosemeters TLD-100 exposed to distinct baker protocols, irradiation and reading; Respuesta termoluminiscente de dosimetros TLD-100 sujetos a distintos protocolos de horneado, irradiacion y lectura

    The interest that motivated the realization of this work is the opposing discrepancy among the values of the efficiency thermoluminescent of heavy charged particles (PCP) regarding gamma radiation ({eta}{sub PCP}, {gamma}) reported in different works and gathered recently for Horowitz (Ho 01). The measures of relative thermoluminescent efficiency have importance in relation to the dosimetry associated to medical therapy with heavy charged particle. The measurement of {eta}{sub PCP}, {gamma} depends of multiple experimental factors. To understand this dependence it was quantified the effect of using different procedures experimental in the estimate of the relative thermoluminescent efficiency of dosemeters TLD-100 (LiF: Ti; Mg) for protons of 3 MeV regarding gamma rays of {sup 60}Co ({eta}{sub PCP}, {gamma}), varying the lot, the presentation, the one baked and the team reader. When was used the same global procedure values they were obtained for ({eta}{sub PCP}, {gamma}) inside the interval [0.30, 0.58] for the peak 5 and [0.35, 0.76] for the total thermoluminescent signal (Tl). At the use different equipment, baked and lot are obtained maximum differences of 30%, 12% and 6% respectively in the values of ({eta}{sub PCP}, {gamma}) for the peak 5, and 25%, 28% and 7% for the total Tl signal. The changes more significant of 36% and 44% for peak 5 and total signal respectively are obtained when changing the presentation of the dosemeter. As a complementary investigation it was studied the distribution of the Tl signal of each peak in the deconvolution of the curve of brightness with regard to the total signal in exposed dosemeters to high fluence of protons (1x10{sup 10} p/cm{sup 2}) varying the experimental protocol. It was found that the distribution of the Tl signal has a difference of the order of 5% when changing the used reading team. It was observed that the contribution of the peak 5 regarding the total signal are preserved when changing baked and that it results to be 8% greater for the presentation in dosemeters of 1 x 1 x 1 mm{sup 3} that for dosemeters of 0.89 x 3.17 x 3.17 mm{sup 3} of TLD-100. Given the importance of having values of relative thermoluminescent efficiency reliable in applications associated to medical dosimetry, the main conclusion of this work is the recommendation of measuring relative efficiencies following a protocol of careful work and previously defined so much for the charged particle radiation as for the gamma radiation and controlling all the experimental factors involved.

  8. A 9-Year-Old Girl Discovers That Her Mother Was Murdered.

    Schonfeld, David J; Shekunov, Julia; Jellinek, Michael; Stein, Martin T

    Susan was a 9-year-old girl living with her mother; she had never met her father. Her mother returned one evening from her job as a cocktail waitress and Susan met her at the apartment door to let her know they had run out of cat food. Her mother said she would go and buy some the next morning because it was late and she was tired, but Susan insisted she go out that evening because the cat had not eaten all day. Her mother was fatally shot in the parking lot of the convenience store shortly thereafter; since there was no robbery involved, the police suspected it was someone that she knew. Susan's extended family had her move out of the apartment that evening and relocate to live with her aunt and uncle out-of-state. The transition happened quickly. Susan was unable to return to her apartment to pick up any additional belongings and never returned to say goodbye to her friends. The family decided she was too young to attend the funeral.Susan had trouble fitting in with her aunt and uncle's family; they had 2 children who were 8 and 6 years old, and Susan felt she was being treated like a baby. She resented having a bedtime (her mother allowed her to stay up as late as she wished), and she complained that the work at school was boring and her classmates were childish. When the family went to a festival in town, she left abruptly without telling them, which frightened Susan's aunt and uncle. They wanted to be supportive but felt that she needed more structure than her mother had provided her. Susan's aunt and uncle sought bereavement support for Susan from her pediatrician and parenting advice for themselves.

It was just in the last Issue of the Journal (Volume 22, No. 4, January 2007 that we as Editors were pleased and proud to print the laudation by Thomas A. Perfetti of Richard Baker who received the 2006 Tobacco Science Research Conference Lifetime Achievement Award. In this Issue, we have the sad duty to print an obituary for Richard Baker. We have asked Ray Thornton, a former Scientific and Regulatory Manager at BAT to write the obituary, because Ray was a colleague, neighbour and friend of Richard Baker.

    A recent paper by Navarro-Gonzalez et al. [Navarro-Gonzalez R, Navarro KF, de la Rosa J, Iniguez E, Molina P, Miranda LD, Morales P, Cienfuegos E, Coll P, Raulin F, et al. (2006) Proc Natl Acad Sci USA 103:16089-16094] claims to show that the Viking GCMS (gas chromatograph-mass spectrometer) experiment, which carried out a search for organic matter at the surface of Mars in 1976, "may have been blind to low levels of organics." To rebut this assertion, the Viking experiment, test data, and results on Mars are reviewed, and the fallacies in the design, execution, and interpretation of the new experiments presented by Navarro-Gonzalez et al. are critically examined.
