    Krupp, Edwin C.

    2003-12-01

    Public perceptions of human prehistory were transformed in the 1960s by astronomer Gerald Stanley Hawkins, who died suddenly and unexpectedly of a heart attack on 26 May 2003 at Hawkridge Farm, in Virginia, near Washington, D.C. His astronomical analysis of Stonehenge, first published in "Nature" on 26 October 1963, and subsequently developed and framed with historical and cultural context in a best-selling book, "Stonehenge Decoded" (1965, in collaboration with John B. White), was also showcased internationally at the time in a one-hour CBS television documentary special, "The Mystery of Stonehenge". The high-profile, unconventional, and cross-disciplinary character of Hawkins's celestial interpretation of Stonehenge alignments and his configuration of the monument as an eclipse predictor attracted archaeological skepticism that provided the controversy desired by the makers of the television program. Antagonism was contrived between Hawkins and archaeologist Richard J.C. Atkinson by the production team to introduce conflict that would enhance audience interest in the subject, and the televised dispute troubled both men for decades. By the early 1970s, however, Hawkins had inspired others to examine the astronomical potential of ancient and prehistoric monuments in many parts of the world. He ignited modern studies of archaeoastronomy. In fact, in a second book on the subject, "Beyond Stonehenge" (1973), Hawkins reported his expanding perspective with accounts of his fieldwork on New Kingdom temples in Egypt, on the giant geoglyphs near Nazca, Peru, and at other sites. He also brought the work of other investigators to the attention of his many readers. He established methods and protocols for alignment studies and invited others to use them. Following, in a sense, the footsteps Sir J. Norman Lockyer left among the antiquities in the late nineteenth and early twentieth century, Hawkins reexamined the alignments of several Egyptian temples, documented significant

    2018-02-01

    A complete foundational discussion of acceleration in the context of Special Relativity (SR) is presented. Acceleration allows the measurement of a Lorentz-FitzGerald body contraction created. It is argued that in the back scattering of a probing laser beam from a relativistic flying electron cloud mirror generated by an ultra-intense laser pulse, a first measurement of a Lorentz-FitzGerald body contraction is feasible.

    2013-03-01

    Full Text Available The Nobel Prize winner Karl Ferdinand Braun has not left anyconsiderable writings on the philosophy of science. Nevertheless, hisphilosophical excursions help us to understand his creative work in physics and the philosophical positions of his disciples. Braun emphasized the fundamental position of the so-called “integral laws” to which the law of conservation of energy belongs. He was a consecutive empiricist and emphasized the relativity of physical schemes and models with respect to experimental devices. I n the style of some German physicists he proclaimed the oscillatory unification of the theory of electricity and optics.

    2005-01-01

    Full text of publication follows: This paper describes the status of the GERALD interactive workbench for the analysis of radiation transport problems. GERALD basically guides the user through the various steps that are necessary to solve a radiation transport problem, and is aimed at education, research and industry. The advantages of such workbench are many: quality assurance of problem setup, interaction of the user with problem solution, preservation of theory and legacy research codes, and rapid proto-typing and testing of new methods. The environment is of general applicability catering for analytical, deterministic and stochastic analysis of the radiation problem and is not tied to one specific solution method or code. However, GERALD is being developed as a portable, modular, open source framework which renders itself quite naturally to the coupling of existing computational tools through specifically developed plug-ins. By offering a common route for setting up, solving and analyzing radiation transport problems GERALD offers the possibility of methods intercomparison and validation. Such flexible radiation transport environment will also facilitate the coupling of radiation physics methods to other physical phenomena and their application to other areas of application such as medical physics and the environment.

    Hughes, Robert E.

    2007-12-01

    Gerald Frederick Tape, a distinguished science statesman and administrator, died on November 20, 2005. Jerry, as he was known to all, took on many diverse and important responsibilities throughout his life and dealt with them with quiet authority and grace. This was the hallmark of his life. The Board of Trustees of Associated Universities, Inc., which he served for many years, expressed this in its condolences, writing "Jerry personified integrity, thoroughness and dedication. His sensitivity for the views of others, his sincerity, his personal commitment, his calm approach and his unfailing good humor were all greatly admired and respected." Jerry was born in Ann Arbor, Michigan on May 29, 1915 but grew up in Milan, a nearby country farm community, and in Ypsilanti where his father was Principal of Michigan State Normal College, which later became Eastern Michigan University (EMU). It was there that he first became interested in physics. It was there also that he met and courted Josephine Waffen, who later would become his wife for more than sixty-six years and fill their lives with three loving sons, Walter, James, and Thomas. Upon graduation from EMU, Jerry was awarded a scholarship that took him to the University of Michigan where he earned a Ph.D. in Physics, researching the decay modes of the radioisotopes of iodine. In the Fall of 1939, during the waning days of the Great Depression, he was offered an Instructorship in the Physics Department of Cornell University, a promising start for a fruitful academic career. He brought his bride Jo to Ithaca and joined the cyclotron group under Robert Bacher and Willy Higginbotham while devising a laboratory course in nuclear techniques for graduate students. Bacher and Higginbotham soon left Cornell to join a new wartime laboratory at the Massachusetts Institute of Technology (MIT) and many other colleagues were "drafted" for war work. Bacher persuaded Jerry to join him at the MIT Radiation Laboratory in February

  13. The odontological identification of Eva Braun Hitler.

    Science.gov (United States)

    Keiser-Nielsen, S; Strøm, F

    1983-01-01

    On May 7th-9th, 1945, a team of Russian pathologists autopsied several bodies found in and near the Fuehrer Bunker in Berlin; among them, a female body (No. 13) was later identified as that of Eva Braun Hitler (EBH), mainly by means of a gold bridge from the lower right jaw. A postmortem photograph of this bridge also shows a separate gold filling. Data now available on the dental treatment of EBH have permitted the present authors to substantiate that this gold filling also came from the mouth of EBH. Further speculation about the fate of EBH would henceforth seem professionally unfounded.

    Sop, Aaron L; Mehlman, Charles T; Meiss, Ludwig

    2003-03-01

    Throughout the history of medicine, many great physicians have originated or popularized ideas that have resulted in their names being attached to a device, procedure, or disease process. Hyphenated eponyms are especially interesting, for there are always underlying stories that explicate how people became associates in history. This paper will describe a bit of hyphenated history regarding orthopaedic trauma, specifically, the development of the Böhler-Braun frame. The lives of two great surgeons associated with this device, Lorenz Böhler, the "father of traumatology," and Heinrich Braun, the "father of local anesthesia," will also be reviewed.

    2012-01-01

    In 1950, Dr. Wernher von Braun and approximately 100 of his team members came to Huntsville, Alabama, to begin work with the Army on what would later become America's historic space program. He would later serve as the first director of the Marshall Space Flight Center and led the development of the Saturn V launch vehicle that launched seven crewed American mission to the moon, as well as America s first space station, Skylab. Von Braun is best known for his team s technical achievements. He realized his dream of exploring outer space by helping place humans on the moon. His engineering and managerial talent during the Apollo era had contributed to a technological revolution. He was by all accounts a good engineer, but he was only one among many. What set Von Braun apart were his charisma, his vision, and his leadership skills. He inspired loyalty and dedication in the people around him. He understood the importance of communicating his vision to his team, to political and business leaders and the public. Today, the Marshall Center continues his vision by pursuing engineering and scientific projects that will continue to open space to exploration. This presentation will discuss Von Braun's impact on Huntsville, the Marshall Center, the nation and the world and look at his contributions in context of where world space exploration is today.

    The relaxation reaction of a system that follows from the Le Chatelier-Braun principle and weakens the result of an external influence turns out to be more intense under a complex action. A method for quantitative determination of the weakening effect for simple and complex actions is suggested.

  1. Braun-Le Chatelier principle in dissipative thermodynamics

    OpenAIRE

    Pavelka, Michal; Grmela, Miroslav

    2016-01-01

    Braun-Le Chatelier principle is a fundamental result of equilibrium thermodynamics, showing how stable equilibrium states shift when external conditions are varied. The principle follows from convexity of thermodynamic potential. Analogously, from convexity of dissipation potential it follows how steady non-equilibrium states shift when thermodynamic forces are varied, which is the extension of the principle to dissipative thermodynamics.

    Full Text Available The Chippewa novelist Gerald Vizenor puts across his interconnected politico-philosophical notions of “survivance” and “terminal creeds” in his early novel, Bearheart. To do so, Vizenor implemented some of the aesthetic strategies of magical realism. He filled his novel with an excessive amount of bizarrely sexual and violent scenes—which turn out to be magical—in order to “upset” the established standards of normality. Moreover, he used American Indian mythic folktales of transformation and metamorphosis, a magical realist technique, to re-shape the cultural and tribal identity in Bearheart’s modernized context.

Er setzt dazu beim Übergang zur Zweiten Moderne an und betrachtet anhand von neun Fallbeispielen gelungene und weniger gelungene Visualisierungen. Durch die verkürzte Aufarbeitung des Verhältnisses der Soziologie zum Bild bleiben jedoch wichtige Einsichten unberücksichtigt, sodass BECKs Empfehlungen, die Zahl der Visualisierungen und die visuelle Kompetenz zu erhöhen, kaum geeignet sind, die Skepsis in der Soziologie gegenüber Visualisierungen zu überwinden.

    Whipple surgery (pancreaticodeudenectomy) has a high complication rate. We aimed to evaluate whether adding Braun jejunojejunostomy (side-to-side anastomosis of afferent and efferent loops distal to the gastrojejunostomy site) to a standard Whipple procedure would reduce postoperative complications. We conducted a randomized clinical trial comparing patients who underwent standard Whipple surgery (standard group) and patients who underwent standard Whipple surgery with Braun jejunojejunostomy (Braun group). Patients were followed for 1 month after the procedure and postoperative complications were recorded. Our study included 30 patients: 15 in the Braun and 15 in the standard group. In the Braun group, 4 (26.7%) patients experienced 6 complications, whereas in the standard group, 7 (46.7%) patients experienced 11 complications (p = 0.14). Complications in the Braun group were gastrointestinal bleeding and wound infection (n = 1 each) and delayed gastric emptying and pulmonary infection (n = 2 each). Complications in the standard group were death, pancreatic anastomosis leak and biliary anastomosis leak (n = 1 each); gastrointestinal bleeding (n = 2); and afferent loop syndrome and delayed gastric emptying (n = 3 each). There was no significant difference between groups in the subtypes of complications. Our results showed that adding Braun jejunojejunostomy to standard Whipple procedure was associated with lower rates of afferent loop syndrome and delayed gastric emptying. However, more studies are needed to define the role of Braun jejunojejunostomy in this regard. IRCT2014020316473N1 (www.irct.ir).

  1. Albert Einstein and Wernher von Braun - the two great German-American physicists seen in a historical perspective.

    Science.gov (United States)

    Winterberg, Friedwardt

    2008-04-01

    It was Albert Einstein who for the first time changed our view of the universe to be a non-euclidean curved space-time. And it was Wernher von Braun who blazed the trail to take us into this universe, leaving for the first time the gravitational field of our planet earth, with the landing a man on the moon the greatest event in human history. Both these great physicists did this on the shoulders of giants. Albert Einstein on the shoulders of his landsman, the mathematician Bernhard Riemann, and Wernher von Braun on the shoulders of Goddard and Oberth. Both Einstein and von Braun made a Faustian pact with the devil, von Braun by accepting research funds from Hitler, and Einstein by urging Roosvelt to build the atom bomb (against Hitler). Both of these great men later regretted the use of their work for the killing of innocent bystanders, even though in the end the invention of nuclear energy and space flight is for the benefit of man. Their example serves as a warning for all of us. It can be formulated as follows: ``Can I in good conscience accept research funds from the military to advance scientific knowledge, for weapons developed against an abstract enemy I never have met in person?'' Weapons if used do not differentiate between the scientist, who invented these weapons, and the non-scientist.

    Full Text Available Brassicaceae are promising oil feedstock for cultivation in centralsouthern Italy. Therefore, a two-year investigation on Brassica carinata A. Braun (cv. CT 204 was carried out in three sites of Apulia region [Site 1, Alberobello - Murgia foreland; Site 2, Troia (Foggia - Daunian sub-Apennines; Site 3, Monteroni (Lecce - Area of Salento], and in one site of Basilicata region (Site 4, Hill of Matera. The aim was to identify site-specific management practices [by comparing minimum vs conventional tillage, low sowing density vs high sowing density; different levels of nitrogen (N supply and organic fertilisers] in the four different marginal areas, to achieve optimum yield performance for biodiesel prospective production. The crop showed a good adaptability in the study sites, and the highest N level positively influenced the yield performance in Sites 1, 2 and 3. Moreover, the reduction of mechanical operations (minimum tillage did not negatively influence crop production and seed oil content. The highest density of sowing tested determined the best crop performance in Site 3, particularly showing the maximum seed oil content with the lowest N supply. Finally, in Site 4 the compost mixed with mineral N fertiliser as well as the sewage sludge from urban wastewater determined productive results comparable to those obtained with mineral fertiliser, evidencing that organic fertilisers could (partially or completely substitute the mineral one for this crop in the study site. On the whole, seed yield and oil content showed a potential for biodiesel production of Brassica carinata cultivated with site-specific agronomic techniques in four different marginal areas of Southern Italy, suggesting it can be likely achieved the crop environmental adaptation.

    Full Text Available In East Africa, Ethiopian mustard (Brassica carinata A. Braun is cultivated primarily for its leaves, but in Ethiopia preference is high for oil in the seed. Dual purpose importance of the seeds for planting and for oil suggests the need to improve seed production efficiency through understanding variation pattern for floral morphology and seed characters. We investigated genetic diversity and correlations for floral and seed characteristics among 14 accessions of Ethiopian mustard to improve seed set and yield. Field trials were conducted during 2008 and 2009; flowers were examined for short stamen height, long stamen height, pistil height, and silliqua for seed weight, seeds/silliqua and silliqua/plant. Results were largely consistent between years, indicating that the variation measured was mainly controlled by genetic factors. High genetic variation for seed characters and reproductive phenology among the accessions was noted. The number of days to appearance of flowers showed high discriminatory ability among the accessions. A wide continuous variation was observed among accessions for anther-stigma separation. Accessions 1, 3 and 14 were identified as early flowering. A significant and positive correlation coefficient between short stamen height and seed weight indicated a substantial complementation among these characters for seed yield improvement. The short stamen height is a good indicator for selection in favour of seed commercialization and indices for selection of pollen parent for seed yield improvement. Accessions 5, 7, 14, 16 and 22 are best for multiple characters and are recommended for seed production for any of the seasons in Arusha, Tanzania.

    This work is devoted to the calculation of responses as functions of neutron energy for a paired set of Andersson-Braun rem counters, which is commercially available. Different Monte Carlo codes such as MCNP, LAHET, HADRON and MCNPX were applied in the calculations. The study extended to frontal, lateral and isotropic neutron incidence. For an estimation of the contribution of charged high-energy particles to the reading, the responses to protons and pions were also determined. The results obtained give good bases for the practical use of the new instrument in high-energy neutron fields.

    2009-12-01

    Over his entire career, Gerald Epstein has toiled at the nexus of science, technology, and security. From 2003 to 2009, he was Senior Fellow for Science and Security at the Center for Strategic and International Studies Homeland Security Program, where he worked on reducing biological weapons threats, improving national preparedness, and easing potential tensions between the scientific research and national security communities. Epstein came to CSIS from the Institute for Defense Analyses. From 1996 to 2001, he served in the White House Office of Science and Technology Policy. And from 1983 to 1989, and again from 1991 until its demise in 1995, Epstein worked at the Congressional Office of Technology Assessment, where he directed a study on the proliferation of weapons of mass destruction, alongside research on other global security topics. A recognized expert in biological risk reduction, Epstein was actually trained as a physicist, having received SB degrees in physics and electrical engineering from MIT, and a PhD in physics from the University of California at Berkeley. How, then, did he come to study the evolving threat from bioterrorism? "What compelled me about bioterrorism was that it was a stellar example of a topic that would lead to a train wreck between the scientific community and the security community unless they figured out how to work together," he said. "The distance between a laboratory and a very large consequence event is a lot shorter in biology than in any other field. I got into bioterrorism to help make sure that the security community doesn't get so scared of the science that it shuts it down, and that the science community isn't so oblivious of security concerns that it pays no attention to them." Epstein spoke on November 6, 2009, with contributing writer Madeline Drexler, author of Emerging Epidemics: The Menace of New Infections (Penguin, 2009), an updated version of an earlier volume. Drexler holds a visiting appointment at the

    Full Text Available Tomato is considered one of the most widely grown vegetable crops in the world and production of it is rising every year in Croatia as well as in the world. This research paper shows results on tomato leaf mould caused by Passalora fulva (Cooke U.Braun & Crous (syn. Cladosporium fulvum (Cooke, which can cause significant reduction of yield and quality of tomato. Other than economic loss, tomato leaf mould can be the cause of allergies because it produces lots of spores. During research, the following materials and methods have been used: collecting samples of plant material infected with tomato leaf mould and assessments of disease intensity, isolation and determination of the pathogen, detecting pathotypes using biassay, susceptibility testing of different tomato genotypes infected with P. fulva, molecular identification and testing the effects of essential oils in vitro on conidia germination. Visual controls of greenhouse and outdoor growing tomato were conducted during the period from 2006 to 2011. Samples (17 from 14 localities in 10 counties (Istra County, Koprivnica-Križevci County, KrapinaZagorje County, Međimurje County, Osijek-BaranjaCounty, Primorje-Gorski Kotar County, Varaždin County, Virovitica-Podravina County, Zadar County and Zagreb County were collected. Symptoms were detected on 6 different tomato genotypes: Belle, Jeremy, Minaret, Amaneta, Gravitet and test genotype. Outdoors, P. fulva was not found. For isolation and determination of P. fulva 4 different growing media were used: PDA (potato – dextrose agar, tomato – agar, carrot – agar and V8 – agar. By measuring the size of conidia on carrot – agar it was determined that they were the closest in size to the conidia from infected tomato leaf. Bioassay for the first time in Croatia confirmed presence of two different physiological pathotypes of P. fulva, Cf – 0 and Cf – 5. Other pathotypes obtained by bioassay were not confirmed by sequencing because the

    Full Text Available The development of energy crops can provide environmental benefits and may represent an opportunity to improve agriculture in areas considered at low productivity. In this work, we studied the energy potential of two species (Brassica carinata A. Braun and Cynara cardunculus L. and their seed oil productivity under different growth conditions. Furthermore, the biodiesel from the oil extracted from the seeds of these species was produced and analysed in term of utilisation as fuels in compression ignition engines. In particular, the spray penetration and shape ratio were measured in a constant-volume chamber and compared with the results obtained with a standard diesel fuel. These results were obtained using a standard common rail injection system at different injection pressure, injection duration, and constant-volume chamber pressure.

    2009-01-01

    Full Text Available We employed Murine GeneChips to delineate the global transcriptional profiles of the livers, lungs, and spleens in a mouse pneumonic plague infection model with wild-type (WT Y. pestis CO92 and its Braun lipoprotein (Δlpp mutant with reduced virulence. These organs showed differential transcriptional responses to infection with WT Y. pestis, but the overall host functional processes affected were similar across all three tissues. Gene expression alterations were found in inflammation, cytokine signaling, and apoptotic cell death-associated genes. Comparison of WT and Δlpp mutant-infected mice indicated significant overlap in lipopolysaccharide- (LPS- associated gene expression, but the absence of Lpp perturbed host cell signaling at critical regulatory junctions resulting in altered immune response and possibly host cell apoptosis. We generated a putative signaling pathway including major inflammatory components that could account for the synergistic action of LPS and Lpp and provided the mechanistic basis of attenuation caused by deletion of the lpp gene from Y. pestis in a mouse model of pneumonic plague.

  13. Comparative study of the oospore morphology of two populations of a rare species Chara baueri A. Braun in Cedynia (Poland and Batzlow (Germany

    2012-06-01

    Full Text Available Morphological features of oospores of Chara baueri A. Braun, one of the rarest charophyte species worldwide, were studied based on 100 oospores collected from a small and temporarily dried mid-field pond near Cedynia, Western Poland. This is the first Polish and fifth presently known locality of this species. For comparison 67 oospores from a German population (similar pond localized near Batzlow, Germany were also measured. So far, data on morphology of C. baueri oospores as well as the species ecology are limited. The only more detailed study of oospores for this species was earlier performed on 15 oospores from Kazakhstan. Largest polar axis (LPA, length, largest equatorial diameter (LED, width, isopolarity index (ISI = LPA/LED × 100, number of ridges, width of fossa, distance from apical pole to LED (AND and anisipolarity index (ANI = AND/LPA × 100 were measured. The comparative analysis revealed that the oospores from Poland are generally bigger and more prolate than the Ger­man ones. The differences for most of studied parameters were statistically significant. The finding is discussed in the context of habitat differentiation of both studied sites. Moreover, the results obtained of oospore measurements for both populations differs from most of the data known so far from the literature.

    Full Text Available Braun/murein lipoprotein (Lpp is involved in inflammatory responses and septic shock. We previously characterized a Δlpp mutant of Yersinia pestis CO92 and found that this mutant was defective in surviving in macrophages and was attenuated in a mouse inhalation model of plague when compared to the highly virulent wild-type (WT bacterium. We performed global transcriptional profiling of WT Y. pestis and its Δlpp mutant using microarrays. The organisms were cultured at 26 and 37 degrees Celsius to simulate the flea vector and mammalian host environments, respectively. Our data revealed vastly different effects of lpp mutation on the transcriptomes of Y. pestis grown at 37 versus 26C. While the absence of Lpp resulted mainly in the downregulation of metabolic genes at 26C, the Y. pestis Δlpp mutant cultured at 37C exhibited profound alterations in stress response and virulence genes, compared to WT bacteria. We investigated one of the stress-related genes (htrA downregulated in the Δlpp mutant relative to WT Y. pestis. Indeed, complementation of the Δlpp mutant with the htrA gene restored intracellular survival of the Y. pestis Δlpp mutant. Our results support a role for Lpp in Y. pestis adaptation to the host environment, possibly via transcriptional activation of htrA.

    Currently, there is no FDA-approved vaccine against Yersinia pestis, the causative agent of bubonic and pneumonic plague. Since both humoral immunity and cell-mediated immunity are essential in providing the host with protection against plague, we developed a live-attenuated vaccine strain by deleting the Braun lipoprotein (lpp) and plasminogen-activating protease (pla) genes from Y. pestis CO92. The Δlpp Δpla double isogenic mutant was highly attenuated in evoking both bubonic and pneumonic plague in a mouse model. Further, animals immunized with the mutant by either the intranasal or the subcutaneous route were significantly protected from developing subsequent pneumonic plague. In mice, the mutant poorly disseminated to peripheral organs and the production of proinflammatory cytokines concurrently decreased. Histopathologically, reduced damage to the lungs and livers of mice infected with the Δlpp Δpla double mutant compared to the level of damage in wild-type (WT) CO92-challenged animals was observed. The Δlpp Δpla mutant-immunized mice elicited a humoral immune response to the WT bacterium, as well as to CO92-specific antigens. Moreover, T cells from mutant-immunized animals exhibited significantly higher proliferative responses, when stimulated ex vivo with heat-killed WT CO92 antigens, than mice immunized with the same sublethal dose of WT CO92. Likewise, T cells from the mutant-immunized mice produced more gamma interferon (IFN-γ) and interleukin-4. These animals had an increasing number of tumor necrosis factor alpha (TNF-α)-producing CD4(+) and CD8(+) T cells than WT CO92-infected mice. These data emphasize the role of TNF-α and IFN-γ in protecting mice against pneumonic plague. Overall, our studies provide evidence that deletion of the lpp and pla genes acts synergistically in protecting animals against pneumonic plague, and we have demonstrated an immunological basis for this protection.

    We recently characterized the Δlpp Δpla double in-frame deletion mutant of Yersinia pestis CO92 molecularly, biologically, and immunologically. While Braun lipoprotein (Lpp) activates toll-like receptor-2 to initiate an inflammatory cascade, plasminogen activator (Pla) protease facilitates bacterial dissemination in the host. The Δlpp Δpla double mutant was highly attenuated in evoking bubonic and pneumonic plague, was rapidly cleared from mouse organs, and generated humoral and cell-mediated immune responses to provide subsequent protection to mice against a lethal challenge dose of wild-type (WT) CO92. Here, we further characterized the Δlpp Δpla double mutant in two murine macrophage cell lines as well as in primary human monocyte-derived macrophages to gauge its potential as a live-attenuated vaccine candidate. We first demonstrated that the Δpla single and the Δlpp Δpla double mutant were unable to survive efficiently in murine and human macrophages, unlike WT CO92. We observed that the levels of Pla and its associated protease activity were not affected in the Δlpp single mutant, and, likewise, deletion of the pla gene from WT CO92 did not alter Lpp levels. Further, our study revealed that both Lpp and Pla contributed to the intracellular survival of WT CO92 via different mechanisms. Importantly, the ability of the Δlpp Δpla double mutant to be phagocytized by macrophages, to stimulate production of tumor necrosis factor-α and interleukin-6, and to activate the nitric oxide killing pathways of the host cells remained unaltered when compared to the WT CO92-infected macrophages. Finally, macrophages infected with either the WT CO92 or the Δlpp Δpla double mutant were equally efficient in their uptake of zymosan particles as determined by flow cytometric analysis. Overall, our data indicated that although the Δlpp Δpla double mutant of Y. pestis CO92 was highly attenuated, it retained the ability to elicit innate and subsequent acquired immune

In his endeavours to understand the universe in many manifestations from nuclei all the way to the stars, he has been influenced by some of the most prominent physicists of the 20th century, and he himself, in turn, has influenced a great many scholars. This volume, a collection of articles dedicated to Gerry on his 85th birthday, contains discussions of many of the issues which have at

    Full Text Available This study was carried out with the objective to estimate the genotypic variability and other yield related traits of Ethiopian mustard in North West Ethiopia. A total of 36 genotypes of Ethiopian mustard were considered for this study. Analysis of variance was computed to contrast the variability within the collected genotypes based on yield and other yield related traits. The results revealed highly significant values(p<0.01 for days to maturity, grain filling period, number of pod per plot, secondary branches per plant, harvest index, seed yield per plot, seed yield per hectare and oil content. Significant differences (p<0.05 were noted for days to flowering, plant height, primary branch per plant, biomass per plot, oil yield per plot differences among the genotypes. Genotypic coefficient of variation (GCV % was lower than phenotypic coefficient of variation (PCV % for all the traits studied. High genetic advance with heritability was observed in the following characters; plant height, biomass of the plant, number of secondary branch per plant and grain filling period. There are variations in the extent of genetic variability, heritability and genetic advance of traits which can facilitate selection for further improvement of important traits of Ethiopian mustard. Therefore, it can be concluded that the variability within Ethiopian mustard genotypes collected from different areas of northern Ethiopia is high and vital for better crop improvement.

    Full Text Available Brassica carinata (BBCC, 2n=34 has still to emerge as a major oilseed crop owing to poor agronomic attributes like long stature, long maturity duration and low seed yield. The restricted amount of genetic variability available in natural B. carinata necessitates utilization of new sources of variability for broadening its genetic base. Interspecific hybridization followed by selection in selfed and back cross progenies was employed to generate useful variability into B. carinata cv ˈPC5ˈ from elite lines of Brassica napus (AACC, 2n=38 and Brassica juncea (AABB, 2n=36. The morphological evaluation of 24 stable introgressed progenies revealed wide range of variability for key economic traits. The progenies with mean maturity duration of 161 ± 2.1 days, short stature of 139.5 ± 6.5 cm and seed yield per plant of 18.6 ± 2.0 g in comparison to the corresponding figures of 168 ± 4.6 days, 230.6 ± 12.7 cm and 12.0 ± 2.4 g in ˈPC5ˈ (recurrent parent were recovered. Diversity analysis at morphological level revealed that 22 out of 24 stable introgressed progenies were grouped with B. carinata ˈPC5ˈ at average taxonomic distance of 1.19. The diversity at molecular level using 25 polymorphic and reproducible RAPD primers revealed that 19 out of 21 introgressed progenies grouped with B. carinata ˈPC5ˈ at a similarity coefficient of 0.68. The clusters in general represent a wide range of genetic diversity in the back cross lines of B. carinata as a result of introgression of genes from elite lines of B. napus and B. juncea parents.

    Full Text Available The correlation between trophic utilization and morphology was studied for two lizard species (Podarcis melisellensis and P. siculus from two mainland localities in the eastern Adriatic area; this is the first report of trophic and morphometric data for P. melisellensis from mainland populations. Variance partitioning showed that most of the variation in morphological traits for the analyzed lizards was the result of differences between species, and to a lesser extent between sexes. Locality did not have a strong effect on the variation of morphological traits. Prey weight is the only characteristic of prey that generally exhibits correlations with morphological characteristics rather than prey size. The pattern of correlations is generally weaker for P. melisellensis than for P. siculus. Optimal foraging theory predictions were generally confirmed: P. siculus is more constrained by trophic resource availability, with a premium on larger and heavier prey consumed in the less productive locality (SM, which can be relaxed in more productive regions (KL. P. melisellensis shows such constraints only for males in the less productive region (SM. Females of both species consume heavier prey. [Projekat Ministarstva nauke Republike Srbije, br.

    This publication reports on the contribution of brown and hard-coal power plants to gross electricity production, quoting a total of 45.2% for 2013. CO{sub 2} emissions from hard coal rose continuously from 2011 to 2013, largely due to a growing electricity export surplus. By contrast, CO{sub 2} emissions from brown coal power plants decreased slightly, in spite of more electricity being produced from brown coal. This can be explained by the replacement of a number of old power plants with new, more efficient ones in the course of 2012 and 2013. From an environmental viewpoint brown and hard coal carry a heavy burden as energy resources. Their specific characteristics and special features are thus covered in a separate part of the report, giving due consideration to aspects of energy economy, general economy and environmental issues.

    Full Text Available The leaf spot (Mycosphaerella leaf disease = MLD caused by Teratosphaeria nubilosa has caused damage in eucalypt plantations in southern and southeastern Brazil. The need to assess the disease in the field to evaluate of this damage, efficiency control, evaluation of germplasm induces to the necessity of having a visual scale for evaluation of disease. The objective was to develop a diagrammatic scale for young leaves and one for adult leaves of Eucalyptus globules for MLD. To do so, the leaves collected in the field were scanned for image analysis. The damaged area, the healthy leaf area and the external area of the same scale RGB (Red, Green, Blue were determined. Subsequently, it was determinate the levels of severity depending on the sample distribution with seven levels for young leaves and six for adult leaves. For the visual acuity test and validate the scale, the leaves were evaluated for severity, with and without scale. With this proposed scales, the assessors showed good accuracy both for young and adult leaves with R2=0,98 and R2=0,80, respectively. The importance of the development of diagrammatic scales for assessing MLD in eucalyptus must to the fact that allows quantification of the symptoms accurately and precisely.

    2012-01-01

    A monographic revision of the hyphomycete genus Cladosporium s. lat. (Cladosporiaceae, Capnodiales) is presented. It includes a detailed historic overview of Cladosporium and allied genera, with notes on their phylogeny, systematics and ecology. True species of Cladosporium s. str. (anamorphs of Davidiella), are characterised by having coronate conidiogenous loci and conidial hila, i.e., with a convex central dome surrounded by a raised periclinal rim. Recognised species are treated and illustrated with line drawings and photomicrographs (light as well as scanning electron microscopy). Species known from culture are described in vivo as well as in vitro on standardised media and under controlled conditions. Details on host range/substrates and the geographic distribution are given based on published accounts, and a re-examination of numerous herbarium specimens. Various keys are provided to support the identification of Cladosporium species in vivo and in vitro. Morphological datasets are supplemented by DNA barcodes (nuclear ribosomal RNA gene operon, including the internal transcribed spacer regions ITS1 and ITS2, the 5.8S nrDNA, as well as partial actin and translation elongation factor 1-α gene sequences) diagnostic for individual species. In total 993 names assigned to Cladosporium s. lat., including Heterosporium (854 in Cladosporium and 139 in Heterosporium), are treated, of which 169 are recognized in Cladosporium s. str. The other taxa are doubtful, insufficiently known or have been excluded from Cladosporium in its current circumscription and re-allocated to other genera by the authors of this monograph or previous authors. Taxonomic novelties: Cladosporium allicinum (Fr.: Fr.) Bensch, U. Braun & Crous, comb. nov., C. astroideum var. catalinense U. Braun, var. nov., Fusicladium tectonicola (Yong H. He & Z.Y. Zhang) U.

    1984-02-01

    The Atomic Energy Control Board (AECB) has concluded that no additional remedial measures are warranted with regard to the mine water spill which occurred in early January at the Key Lake Mining Corporation facility in northern Saskatchewan, and has advised the company to reconsider its proposal for clean-up of the adjoining Gerald Lake basin. On January 5, an estimated 87 million litres of mine water was accidentally released to the environment when a water storage reservoir at the mine site overflowed. The spilled water flowed into the adjoining Gerald Lake catchment area where it has remained adequately contained

  7. Rocket center Peenemünde — Personal memories

    Science.gov (United States)

    Dannenberg, Konrad; Stuhlinger, Ernst

    Von Braun built his first rockets as a young teenager. At 14, he started making plans for rockets for human travel to the Moon and Mars. The German Army began a rocket program in 1929. Two years later, Colonel (later General) Becker contacted von Braun who experimented with rockets in Berlin, gave him a contract in 1932, and, jointly with the Air Force, in 1936 built the rocket center Peenemünde where von Braun and his team developed the A-4 (V-2) rocket under Army auspices, while the Air Force developed the V-1 (buzz bomb), wire-guided bombs, and rocket planes. Albert Speer, impressed by the work of the rocketeers, allowed a modest growth of the Peenemünde project; this brought Dannenberg to the von Braun team in 1940. Hitler did not believe in rockets; he ignored the A-4 project until 1942 when he began to support it, expecting that it could turn the fortunes of war for him. He drastically increased the Peenemünde work force and allowed the transfer of soldiers from the front to Peenemünde; that was when Stuhlinger, in 1943, came to Peenemünde as a Pfc.-Ph.D. Later that year, Himmler wrenched the authority over A-4 production out of the Army's hands, put it under his command, and forced production of the immature rocket at Mittelwerk, and its military deployment against targets in France, Belgium, and England. Throughout the development of the A-4 rocket, von Braun was the undisputed leader of the project. Although still immature by the end of the war, the A-4 had proceeded to a status which made it the first successful long-range precision rocket, the prototype for a large number of military rockets built by numerous nations after the war, and for space rockets that launched satellites and traveled to the Moon and the planets.

    2008-12-01

    Full Text Available The establishment of the Mapungubwe National Park has been an objective of several conservationists for many years. The ultimate objective is that this park should become a major component of a Transfrontier National Park shared by Botswana, Zimbabwe and South Africa. The aim of this study was to identify, classify and describe the plant communities present in the Ib land type of the park. Sampling was done by means of the Braun-Blanquet method. A total of 48 stratified random relevés were sampled in the Ib land type. All relevé data were imported into a TURBOVEG database, after which the numerical classification technique TWINSPAN was used as a first approximation. Subsequently, Braun-Blanquet procedures were used to refine data and a phytosociological table was constructed, using the visual editor, MEGATAB. Two plant communities and several subcommunities and variants were identified and described from the phytosociological table.

    Directory of Open Access Journals (Sweden)

    Maximiliano A. Wilson

    2014-04-01

    The results in controls reproduce those found in literature (Braun et al., 2009. The general impairment and the lack of lexicality effect are also in line with current literature on svPPA and are likely explained by semantic impairment (Rogers et al., 2004. Interestingly, the novel result here is the absence of PsH effect in svPPA. This suggests that phonology is not correctly activated and that O-P mappings are also impaired in svPPA.

    It has been just over a decade since we published a paper outlining a new approach to thematic analysis (TA) entitled Using thematic analysis in psychology (Braun & Clarke, 2006). Our approach to TA has become widely used both in and beyond psychology, and particularly in applied research areas, including counselling and psychotherapy. Although TA as a distinct analytic method has increased in popularity over the last decade, we continue to see evidence of confusion about TA – what it is, wha...

  11. Reply [to: Atlantic Tropical Cyclogenetic Processes during SOP-3 NAMMA in the GEOS-5 Global Data Assimilation and Forecast System

    Science.gov (United States)

    Reale, Oreste; Lau, William K.

    2010-01-01

    This article is a Reply to a Comment by Scott Braun on a previously published article by O. Reale, K.-M. Lau, and E. Brin: "Atlantic tropical cyclogenetic processes during SOP-3 NAMMA in the GEOS-5 global data assimilation and forecast system", by Reale, Lau and Brin, hereafter referred to as RA09. RA09 investigated the role of the Saharan Air Layer (SAL) in tropical cyclogenetic processes associated with a non-developing easterly wave observed during the Special Observation Period (SOP-3) phase of the 2006 NASA African Monsoon Multidisciplinary Analyses (MAMMA). The wave was chosen because both interact heavily with Saharan air. Results showed: a) very steep moisture gradients are associated with the SAL in forecasts and analyses even at great distance from the Sahara; b) a thermal dipole (warm above, cool below) in the non-developing case. RA09A suggested that radiative effect of dust may play some role in producing a thermal structure less favorable to cyclogenesis, and also indicated that only global horizontal resolutions on the order of 20-30 kilometers can capture the large-scale transport and the fine thermal structure of the SAL Braun (2010) questions those results attributing the wave dissipation to midlatitude air. The core discussion is on a dry filament preceding the wave, on the presence of dust, and on the origin of the air contained in this dry filament. In the 'Reply', higher resolution analyses than the ones used by Braun, taken at almost coincident times with Aqua and Terra passes, are shown, to emphasize how the channel of dry air associated with W1 is indeed rich in dust. Backtrajectories on a higher resolution grid are also performed, leading to results drastically different from Braun (2010), and in particularly showing that there is a clear contribution of Saharan air. Finally, the 'Reply' presents evidence on that analyses at a horizontal resolution of one degree are inadequate to investigate such feature.

    Full Text Available Chinese foreign policy has been transformed in recent years. This article seeks to provide a systematic analysis of the most salient features of the new Chinese foreign policy. It identifies five such features. Based on these features, the article suggests that China is poised to become a true global power. This view differs significantly from Gerald Segal’s famous claim in 1999 that China was no more than a middle power. The article utilizes many current Chinese sources to help readers understand China’s new motives and goals in international and regional affairs.

    Science.gov (United States)

    Strobl, G. F. X.; Laroche, G.; Rasch, K.-D.; Hey, G.

    In the early 1950s, Bell Laboratories in the USA investigated possible applications of silicon semiconductors in electronics. While improving transistors, Bell scientists Gerald Pearson and Calvin Fuller invented the first silicon solar cell. That first effort was further improved for applications in remote humid locations by Darryl Chapin [1]. The first experiment with silicon yielded an efficiency of 2.3%. Improvements with regard to the dopants, the metallic contacts to the p- and n-side and the application of an antireflection coating led to efficiencies of 4%. In 1954, cells with 6% efficiency could be reliably manufactured.

    The topic of this thesis is the Gerald Ford's program WIN as a policy aimed at inflation. WIN is certainly determined by the time it was developer in. The essential aspects are unemployment rate, which had reached 9 percents in the 1970s, and the neglect of monetary policy. Ford's announced policy was the exact opposite of that of Nixon's. The infamous saving in the times of crisis was relatively mild, thus the speculations of an attempt of Ford's PR is an explanation. The CPI level had lower...

    A similarity transformation is used to study the expansion of a planetary nebula which is driven by a fast stellar wind as well as an expanding H II region. The undisturbed gas is taken to be the remnant of a slow, red giant wind. The present analysis improves upon Kwok, Purton, and FitzGerald's colliding wind model for the formation of planetary nebulae since it includes the dynamical influence of ionization fronts, and calculates the variation of velocity and density within the flow

A primary objective of the organization was to achieve a formal relationship with the Association of American Medical Colleges (AAMC) through membership in the Council of Academic Societies (CAS). Initial steps in establishing AAHSL are examined, including its efforts to join CAS. The author pays tribute to AAHSL's founders, in particular Gerald Oppenheimer, without whose vision and leadership AAHSL would not have been formed.

    Killoran, C E; Abbott, M; McKusick, V A; Biesecker, L G

    2000-07-01

    The polydactyly, imperforate anus, vertebral anomalies syndrome (PIV, OMIM 174100) was determined as a distinct syndrome by Say and Gerald in 1968 (Say B, Gerald PS. Lancet 1968: 2: 688). We noted that the features of PIV overlap with the VATER association and Pallister-Hall syndrome (PHS, OMIM 146510), which includes polydactyly, (central or postaxial), shortened fingers, hypoplastic nails, renal anomalies, imperforate anus, and hypothalamic hamartoma. Truncation mutations in GL13, a zinc finger transcription factor gene, have been shown to cause PHS. We performed a molecular evaluation on a patient diagnosed with PIV, whose mother, grandfather, and maternal aunt had similar malformations. We sequenced the GLI3 gene in the patient to determine if she had a mutation. The patient was found to have a deletion in nucleotides 2188-2207 causing a frameshift mutation that predicts a truncated protein product of the gene. Later clinical studies demonstrated that the patient also has a hypothalamic hamartoma, a finding in PHS. We concluded that this family had atypical PHS and not PIV. This result has prompted us to re-evaluate the PIV literature to see if PIV is a valid entity. Based on these data and our examination of the literature, we conclude that PIV is not a valid diagnostic entity. We conclude that patients diagnosed with PIV should be reclassified as having VACTERL, or PHS, or another syndrome with overlapping malformations.

    2010-01-01

    AIM: To determine the effect of three digestive tract reconstruction procedures on pouch function, after radical surgery undertaken because of gastric cancer, as assessed by radionuclide dynamic imaging. METHODS: As a measure of the reservoir function, with a designed diet containing technetium-99m (99mTc), the emptying time of the gastric substitute was evaluated using a 99mTc-labeled solid test meal. Immediately after the meal, the patient was placed in front of a γ camera in a supine position and the radioactivity was measured over the whole abdomen every minute. A frame image was obtained. The emptying sequences were recorded by the microprocessor and then stored on a computer disk. According to a computer processing system, the half-emptying actual curve and the fitting curve of food containing isotope in the detected region were depicted, and the half-emptying actual curves of the three reconstruction procedures were directly compared. RESULTS: Of the three reconstruction procedures, the half-emptying time of food containing isotope in the Dual Braun type esophagojejunal anastomosis procedure (51.86 ± 6.43 min) was far closer to normal, significantly better than that of the proximal gastrectomy orthotopic reconstruction (30.07 ± 15.77 min, P = 0.002) and P type esophagojejunal anastomosis (27.88 ± 6.07 min, P = 0.001) methods. The half-emptying actual curve and fitting curves for the Dual Braun type esophagojejunal anastomosis were fairly similar while those of the proximal gastrectomy orthotopic reconstruction and P type esophagojejunal anastomosis were obviously separated, which indicated bad food conservation in the reconstructed pouches. CONCLUSION: Dual Braun type esophagojejunal anastomosis is the most useful of the three procedures for improving food accommodation in patients with a pouch and can retard evacuation of solid food from the reconstructed pouch.

    Full Text Available Previous studies identified a unique plant community on gabbro in the Manyeleti Game Reserve, but it was not formally described. From a Braun-Blanquet analysis of this vegetation, six syntaxa were recognised. These were classified as one association, two subassociations, five variants and one community without syntaxonomic rank. All these syntaxa are newly decribed, and ecologically interpreted by means of habitat data. A quantitive assessment of the woody component of each syntaxon is presented. Ordinations, based on floristic and habitat data, revealed the position of the syntaxa on environmental gradients.

    Full Text Available The vegetation of the Jack Scott Nature Reserve in the Central Bankenveld Veld Type is classified chiefly by the Braun-Blanquet Table Method. Habitat features, physiognomy, total floristic composition, differentiating species, woody plants and prominent grasses and forbs are presented for each community. Characterizing habitat features, in order of importance for the communities, are: exposure, soil texture, geology, slope, aspect, degree of rockiness and previous ploughing. The classification correlates well with the major physiographic and climatic variation in the Reserve and generally does not cut across main physiognomic types. The communities are potentially homogeneous management units.

    This study was conducted to develop simple and low-cost wave drivers that can be used in experiments on string waves. These wave drivers were made using a toothbrush (Oral-B Vitality), an electric shaver (Braun 7505) and a razor (Gillette Fusion Proglide Power). A common feature of all of these product is that they have vibration motors. In the experiments, string waves were generated by transferring these vibrations to a stretched string. By changing the tightness and length of the string, standing waves were generated, and various harmonics were observed.

    2007-07-01

    The launch of Sputnik 1 in 1957 was fuelled by science fiction as well as science fact. The field of early rocketry included the work of Russians Nikolai Rynin and Konstantin Tsiolkovsky, American Robert Goddard, and German engineers Herman Oberth and Wernher Von Braun. All were directly inspired and influenced by early science fiction that heralded a space age decades ahead of time. The work of these pioneers led directly to the development of the technology needed to boost Sputnik skyward. After the launch of Sputnik, the context of the nuclear arms race opened the floodgates for a new wave of apocalyptic fiction.

    The duodeno-gastric reflux was evaluated in 33 patients following gastric surgery by functional hepato-biliary scintigraphy. In 16 of 26 patients with gastric resection a reflux was found. The Y-en-Roux and the retrocolic B II resection with Braun's Anastomosis showed the lowest incidence of reflux. The functional scintigraphy permits an objective diagnosis of reflux without provocation by diagnostic manipulations. The high percentage of accuracy in evaluating reflux recommends the scintigraphy as an optimal method in postoperative reflux control.

  8. Decision paths in complex tasks

    Science.gov (United States)

    Galanter, Eugene

    1991-01-01

    Complex real world action and its prediction and control has escaped analysis by the classical methods of psychological research. The reason is that psychologists have no procedures to parse complex tasks into their constituents. Where such a division can be made, based say on expert judgment, there is no natural scale to measure the positive or negative values of the components. Even if we could assign numbers to task parts, we lack rules i.e., a theory, to combine them into a total task representation. We compare here two plausible theories for the amalgamation of the value of task components. Both of these theories require a numerical representation of motivation, for motivation is the primary variable that guides choice and action in well-learned tasks. We address this problem of motivational quantification and performance prediction by developing psychophysical scales of the desireability or aversiveness of task components based on utility scaling methods (Galanter 1990). We modify methods used originally to scale sensory magnitudes (Stevens and Galanter 1957), and that have been applied recently to the measure of task 'workload' by Gopher and Braune (1984). Our modification uses utility comparison scaling techniques which avoid the unnecessary assumptions made by Gopher and Braune. Formula for the utility of complex tasks based on the theoretical models are used to predict decision and choice of alternate paths to the same goal.

    The objective of this prospective single-blind crossover clinical trial was to evaluate the efficacy of 4 toothbrushes in 33 children undergoing fixed appliance orthodontic therapy. The toothbrushes included in this study were the Braun Oral-B 3D Plaque Remover (Kronberg, Germany), the Philips-Jordan HP 510 (Philips Domestic Appliances, Groningen, The Netherlands), the Lactona orthodontic toothbrush (Bergen op Zoom, The Netherlands), and the Oral-B Advantage Control Grip (Braun); the first 2 are electric, and the last 2 are manual. Every patient tested each type of toothbrush in a randomly designed sequence. Plaque and gingival scores were recorded at baseline and after every 4-week test period. All patients received professional prophylaxis after each clinical evaluation. The data were analyzed with the Friedman test, which showed no significant differences among the 4 brushes for any of the parameters measured. The Wilcoxon signed rank test, comparing the plaque and the gingival scores between the upper and lower jaw for each brush, indicated that plaque removal was more efficient in the lower jaw than in the upper.

  11. Demand Shifting With Thermal Mass in Large Commercial Buildings:Field Tests, Simulation and Audits

    Energy Technology Data Exchange (ETDEWEB)

    Xu, Peng; Haves, Philip; Piette, Mary Ann; Zagreus, Leah

    2005-09-01

    The principle of pre-cooling and demand limiting is to pre-cool buildings at night or in the morning during off-peak hours, storing cooling in the building thermal mass and thereby reducing cooling loads and reducing or shedding related electrical demand during the peak periods. Cost savings are achieved by reducing on-peak energy and demand charges. The potential for utilizing building thermal mass for load shifting and peak demand reduction has been demonstrated in a number of simulation, laboratory, and field studies (Braun 1990, Ruud et al. 1990, Conniff 1991, Andresen and Brandemuehl 1992, Mahajan et al. 1993, Morris et al. 1994, Keeney and Braun 1997, Becker and Paciuk 2002, Xu et al. 2003). This technology appears to have significant potential for demand reduction if applied within an overall demand response program. The primary goal associated with this research is to develop information and tools necessary to assess the viability of and, where appropriate, implement demand response programs involving building thermal mass in buildings throughout California. The project involves evaluating the technology readiness, overall demand reduction potential, and customer acceptance for different classes of buildings. This information can be used along with estimates of the impact of the strategies on energy use to design appropriate incentives for customers.

  12. Seasonality of Water Chemistry, Carbonate Production, and Biometric Features of Two Species of Chara in a Shallow Clear Water Lake

    Directory of Open Access Journals (Sweden)

    Andrzej Pukacz

    2014-01-01

    Full Text Available The objective of this study was to analyze the temporal variability of biometric features and the carbonate production of two charophytes: Chara polyacantha A. Braun and Chara rudis A. Braun against the background of the physical-chemical properties of water. The investigation was carried out in a small, mid-forest Lake Jasne (western Poland. It is a polymictic, mesotrophic, hardwater ecosystem dominated by charophyte vegetation. Each month, 10 individuals of each species were characterized in terms of morphometric features, fresh and dry weight, and the percentage of calcium carbonate. Additionally, physical-chemical parameters of the water were studied. The results of physical-chemical analyses indicated similar habitat conditions for both species. Despite smaller dry weight C. polyacantha was characterized by greater morphological variability and higher rates of growth and percentage share of calcium carbonate in dry mass than C. rudis. The percentage of calcium carbonates in dry mass did not differ significantly between the species and exceeded 60%, reaching the maximum (76% in C. polyacantha in July and August. For both species, distinct correlations between the structure of biomass and morphological features were found. The obtained results show the great importance of charophyte vegetation in carbon cycling and functioning of lake ecosystems.

  13. Protein Adsorption to In-Line Filters of Intravenous Administration Sets.

    2017-10-01

    Ensuring compatibility of administered therapeutic proteins with intravenous administration sets is an important regulatory requirement. A low-dose recovery during administration of low protein concentrations is among the commonly observed incompatibilities, and it is mainly due to adsorption to in-line filters. To better understand this phenomenon, we studied the adsorption of 4 different therapeutic proteins (2 IgG1s, 1 IgG4, and 1 Fc fusion protein) diluted to 0.01 mg/mL in 5% glucose (B. Braun EcoFlac; B. Braun Melsungen AG, Melsungen, Germany) or 0.9% sodium chloride (NaCl; Freeflex; Fresenius Kabi, Friedberg, Germany) solutions to 8 in-line filters (5 positively charged and 3 neutral filters made of different polymers and by different suppliers). The results show certain patterns of protein adsorption, which depend to a large extent on the dilution solution and filter material, and to a much lower extent on the proteins' biophysical properties. Investigation of the filter membranes' zeta potential showed a correlation between the observed adsorption pattern in 5% glucose solution and the filter's surface charge, with higher protein adsorption for the strongly negatively charged membranes. In 0.9% NaCl solution, the surface charges are masked, leading to different adsorption patterns. These results contribute to the general understanding of the protein adsorption to IV infusion filters and allow the design of more efficient compatibility studies.

    Castillo, Marigold; Weiselberg, Eric

    2017-04-01

    Bulimia nervosa was first described in 1979 by British psychiatrist Gerald Russell as a "chronic phase of anorexia nervosa" in which patients overeat and then use compensatory mechanisms, such as self-induced vomiting, laxatives, or prolonged periods of starvation. The characterization of bulimia nervosa continues to evolve with the introduction of the DSM-5 in 2013. In this article, the epidemiology and risk factors of bulimia nervosa are identified and reviewed, along with the medical complications and psychiatric comorbidities. The evaluation of a patient with suspected bulimia nervosa is addressed, with an emphasis on acquiring a complete and thorough history as well as discovering any comorbidities that are present. Management of the patient involves both medical interventions and behavioral counseling in order to address physical, psychological, and social needs. Lastly, a new diagnosis introduced in the DSM-5, purging disorder, is described and discussed. Copyright © 2017 Mosby, Inc. All rights reserved.

  16. [The function of analogies in natural sciences, also in contrast to metaphors and models].

    Science.gov (United States)

    Hentschel, Klaus

    2010-01-01

    This introduction surveys the various functions of analogies in science, medicine and technology. The focus is on their heuristic importance. The productiveness of analogies is linked to the systematic depth and breadth of the established connections. Various examples are presented from different periods in the history of science, most notably Galileo; such late-Victorian Maxwellians as George Francis FitzGerald and Oliver Lodge; and Heinrich HERTZ and Niels BOHR. These examples are examined in terms of the specific differing temporal ranges of their claimed validities. They serve as evidence or counterevidence for various systematic analyses of analogies as put forward by various philosophers of science, most notably Francis Bacon, John Stuart Mill, Ernst Mach, Harald Høffding, Ernest Nagel, Mary Hesse and Peter Achinstein. The analytic framework for analogies supported here is what the cognitive scientist Dedre Gentner has termed structure-mapping.

    Full Text Available Framing analysis, methodically is used to dissect discourse impulses that leading to stigma crystallization. Media frames an issue by using language tools and plays a subconscious role in the attitude and understanding of society. Although, basically, every media does framing, but the problem that comes next is when this framing becomes an interest to postulate the lame proposition socially and logically. This research efforts to analyze in narrative about how religion is mediated by Kompas.com, through framing information issue about the Rape by the Board of Pesantren issue in framing analysis of Zhongdang Pan and Gerald M. Kosicki. In conclusion, the Kompas electronic media framing gives rise to a certain tendency toward the negative stigma of pesantren in the public through a narrowing of news content in the media, especially from the interpretation and reporting analysis that revolves around closed syntactic and syntagmatic interactions.

  18. Science and anti-science

    1997-01-01

    What is good science? What goal--if any--is the proper end of scientific activity? Is there a legitimating authority that scientists mayclaim? Howserious athreat are the anti-science movements? These questions have long been debated but, as Gerald Holton points out, every era must offer its own responses. This book examines these questions not in the abstract but shows their historic roots and the answers emerging from the scientific and political controversies of this century. Employing the case-study method and the concept of scientific thematathat he has pioneered, Holton displays the broad scope of his insight into the workings of science: from the influence of Ernst Mach on twentiethcentury physicists, biologists, psychologists, and other thinkers to the rhetorical strategies used in the work of Albert Einstein, Niels Bohr, and others; from the bickering between Thomas Jefferson and the U.S. Congress over the proper form of federal sponsorship of scientific research to philosophical debates since Oswald...

    International Nuclear Information System (INIS)

    Demoss, D.; Mendelsberg, J.I.

    1992-01-01

    This paper reports on the 1991 zebra mussel veliger settlement monitoring program undertaken to record and evaluate zebra mussel veliger settlement in Lake Erie and Lake Michigan. Studies by Dr. Gerald Mackie of Canada in 1990 indicated veliger settlement may be occurring primarily during short time periods every season corresponding with warmer water temperatures. Veliger settlement monitoring was performed using a plexiglass sampler apparatus. The samplers were simple in design and consisted of a 20-inch-square plexiglass base panel with thirty-six 1 inch x 3 inch clear plexiglass microscope slides attached. The results of the monitoring program indicate the existence of preferential settlement periods for veligers correlating with sustained lake water temperatures above 70 degrees F. Veliger settlement concentrations in the south basin of Lake Michigan appear to be similar to those in western Lake Erie

    Maudlin, Tim

    2012-01-01

    This concise book introduces nonphysicists to the core philosophical issues surrounding the nature and structure of space and time, and is also an ideal resource for physicists interested in the conceptual foundations of space-time theory. Tim Maudlin's broad historical overview examines Aristotelian and Newtonian accounts of space and time, and traces how Galileo's conceptions of relativity and space-time led to Einstein's special and general theories of relativity. Maudlin explains special relativity using a geometrical approach, emphasizing intrinsic space-time structure rather than coordinate systems or reference frames. He gives readers enough detail about special relativity to solve concrete physical problems while presenting general relativity in a more qualitative way, with an informative discussion of the geometrization of gravity, the bending of light, and black holes. Additional topics include the Twins Paradox, the physical aspects of the Lorentz-FitzGerald contraction, the constancy of the speed...

    Full Text Available This study examines the use of retractors and explainers in prepared political speeches of American charismatic presidents. It is based upon the results of psychological analysis of 24 speeches of John F. Kennedy, Ronald Reagan, Barack Obama, and Gerald Ford. The research shows that certain differences may be found in the use of explainers and retractors not along the axis “Charismatic versus Non-Charismatic Presidents”, but with regard to their party affiliation. Rhetoric of Democratic presidents (Kennedy, Obama is characterized by a more explanatory communication style than of Republican ones (Reagan, Ford, which results in respective differences in the use of explainers. As for the retractors, all the four presidents under study tend to use the category moderately, which reveals them as emotionally controlled individuals, able to reconsider their decisions if necessary.

  13. "Kids not rights, is their craving": sex education, gay rights, and the threat of gay teachers.

    Science.gov (United States)

    Graydon, Michael

    2011-08-01

    In July 1977, the Ontario Humans Rights Commission recommended adding sexual orientation to the Code. This move was generally supported but Toronto newspapers and evangelists sought assurances that school boards could still dismiss homosexual teachers. They demanded children be shielded from gay teachers, who they accused of sexual predation. I historically link this to a reenergized fear of homosexuals which emerged during Toronto sex education debates in the 1970s. Later, influenced by Anita Bryant's Save the Children crusade, Toronto newspapers and evangelists argued gay teachers were the dangerous effect of gay rights. After the 1977 murder of Emanuel Jaques and the publication of Gerald Hannon's "Men Loving Boys, Loving Men" article, anti-gay sentiment in Toronto exploded, temporarily halting the progress of gay rights.

    2016-07-01

    Full Text Available The article employs critical concepts from sociology and anthropology to examine the stereotype of the Vanishing Indian and disclose its contradictory character. The article argues that in James Fenimore Cooper’s late novels from the 1840s a type of American Indian appears who can be regarded as a Vanishing Indian in many respects as he displays some slight degree of assimilation but at the same time he can be found to reveal a surprising amount of resistance to the process of vanishing and marginalization. His peculiar mode of survival and his mode of living demonstrate a certain degree of acculturation, which comes close to Gerald Vizenor’s survivance and for which I propose a term critical integration. I base my study on Susquesus (alias Trackless, Cooper’s less well-known character from The Littlepage Manuscripts, a three-book family saga.

    1991-01-01

    The first strategic arms limitation talks resulted in two agreements: the Anti-Ballistic Missile Treaty and the Interim Agreement to Limit Strategic Offensive Arms. Senator Henry M. (Scoop) Jackson (D-Wa.) was concerned about the numerical advantage granted to the USSR by the Latter agreement and proposed an amendment that would prohibit future negotiators from granting the Soviet Union similar terms. This paper discusses the second round of SALT negotiations which opened in November 1972 and continued under presidents Richard M. Nixon, Gerald Ford, and Jimmy Carter. As the negotiators met, U.S. and Soviet scientists and engineers continued their work to develop new nuclear weapons and launchers. Particularly problematic were modern, large ballistic missiles, cruise missiles, and the Soviet Backfire bomber

    1953-01-01

    This paper reviews an experimental geochemical prospecting survey in the Blackbird cobalt-copper mining district. The district is in east-central Idaho, about 20 miles west-southwest of Salmon. The area is one of deeply weathered nearly flat-topped upland surfaces cut by steep-walled valleys which are tributary to the canyon of Panther Creek. Most of the area has a relatively heavy vegetative cover, and outcrops are scarce except on the sides of the steeper valleys* Because of the importance of the surficial deposits and soils and the physiographic history of the region on the interpretation of the geochemical data, a separate chapter on this subject by Gerald H. Richmond follows the following brief description of the geology of the district.

    This paper reports that when President Gerald Ford signed the instruments of ratification for the Geneva Protocol of 1925 on January 22, 1975, a tortured, half-century-long chapter in U.S. arms control policy was brought to a close. Fifty years earlier, at the Geneva Conference for the Control of the International Trade in Arms, Munitions and Implements of War, the United States had played a key role in drafting and reaching agreement on the Protocol for the Prohibition of the Use in War of Asphyxiating, Poisonous or Other Gases and of Bacteriological Methods of Warfare. The protocol, signed by thirty nations, including the United States, on June 17, 1925, prohibits the use in war of asphyxiating, poisonous or other gases, and of all analogous liquids, materials or devices as well as the use of bacteriological methods of warfare

    Then-President Gerald Ford outlines the potential benefits of nuclear power as opposed to the danger of proliferation. He points out that not all nations have the same interest or views toward nuclear energy; but also he says that if a choice must be made, nonproliferation objectives must take precedence over economic and energy benefits. It is pointed out that the management of nuclear energy can be only partial and temporary by technical measures, and that full management can result only if nations realistically face the task prepared to forego preconceived short-term advantages in favor of long-term gains. Coordination of the policies of all nations toward the common goal of nonproliferation is predicted to lead to success

    2004-01-01

    Description: Contents proceedings of Workshop on Common Tools and Interfaces for Deterministic Radiation Transport, for Monte Carlo and Hybrid Codes with a proposal to develop the following: GERALD - A General Environment for Radiation Analysis and Design. GERALD intends to create a unifying software environment where the user can define, solve and analyse a nuclear radiation transport problem using available numerical tools seamlessly. This environment will serve many purposes: teaching, research, industrial needs. It will also help to preserve the existing analytical and numerical knowledge base. This could represent a significant step towards solving the legacy problem. This activity should contribute to attracting young engineers to nuclear science and engineering and contribute to competence and knowledge preservation and management. This proposal was made at the on Workshop on C ommon Tools and Interfaces for Deterministic Radiation Transport, for Monte Carlo and Hybrid Codes , held from 25-26 September 2003 in connection with the conference SNA-2003. A first success with the development of such tools was achieved with the BOT3P2.0 and 3.0 codes providing an easy procedure and mechanism for defining and displaying 3D geometries and materials both in the form of refineable meshes for deterministic codes or Monte Carlo geometries consistent with deterministic models. Advanced SUSD: Improved tools for Sensitivity/Uncertainty Analysis. The development of tools for the analysis and estimation of sensitivities and uncertainties in calculations, or their propagation through complex computational schemes, in the field of neutronics, thermal hydraulics and also thermo-mechanics is of increasing importance for research and engineering applications. These tools allow establishing better margins for engineering designs and for the safe operation of nuclear facilities. Such tools are not sufficiently developed, but their need is increasingly evident in many activities

  4. About an Element of Human Greatness

    2005-01-01

    One of the things Dr. von Braun instinctively knew was that it was as nearly important to explain why we should go into space as to build the machines to take us there. He wrote books and magazine articles, spoke to everyone he could formally and informally, and spent his life to his dying day seeking to educate everyone on the importance of and need for spaceflight. Why should we go? I think there are actually two principle reasons: 1) Because the solar system is filled with cheap, clean energy, and we need to go get it, and, 2) this one may well be even more important, because we need a purpose for ourselves and our country. I think we need an eternal frontier to push up against, our purpose to conquer and settle it. The nice thing about doing that is the solar system is a very rich place, filled with not only mineral wealth but energy, a nearly inexhaustible supply. And if there s one thing this country and this planet desperately needs and is willing to pay for now and forever is energy. The solar system is where it is. We've got to go after it. I believe, then, that Americans have both a self-interest and a patriotic duty to convince ourselves it is time to take another giant step into space. The way to do that is to do what Dr. von Braun did, cut metal and start flying. Success engenders success. Dr. von Braun s grand dream need never die. NASA can spark a twenty-first-century revolution in transportation and energy that could fundamentally change the way we fly through space, power the world, even care for the sick if we do it right. All those things require cheap and clean energy. It exists in the solar system in a variety of forms. Solar energy is the most obvious form, but there are others, including helium-3, which may be the perfect fuel for fusion reactors, and also just happens to cover the Moon. I believe we must go after it. We just need to believe in ourselves and our purpose. I call on all of you here today to join together, get things moving

  5. Optically Anomalous Crystals

    CERN Document Server

    Shtukenberg, Alexander; Kahr, Bart

    2007-01-01

    Optical anomalies in crystals are puzzles that collectively constituted the greatest unsolved problems in crystallography in the 19th Century. The most common anomaly is a discrepancy between a crystal’s symmetry as determined by its shape or by X-ray analysis, and that determined by monitoring the polarization state of traversing light. These discrepancies were perceived as a great impediment to the development of the sciences of crystals on the basis of Curie’s Symmetry Principle, the grand organizing idea in the physical sciences to emerge in the latter half of the 19th Century. Optically Anomalous Crystals begins with an historical introduction covering the contributions of Brewster, Biot, Mallard, Brauns, Tamman, and many other distinguished crystallographers.

    The aim of the study was to ascertain the extent to which temperature influences the utilisation of main carbon sources (reducing substances determined before and after hydrolysis, glycerol and organic acids) by a mixed culture of thermo- and mesophilic bacteria of the genus Bacillus in the course of aerobic batch biodegradation of potato stillage, a high-strength distillery effluent (COD=51.88 g O(2)/l). The experiments were performed at 20, 30, 35, 40, 45, 50, 55, 60 and 63 degrees C, at pH 7, in a 5l working volume stirred-tank bioreactor (Biostat B, B. Braun Biotech International) with a stirrer speed of 550 rpm and aeration at 1.6 vvm. Particular consideration was given to the following issues: (1) the sequence in which the main carbon sources in the stillage were assimilated and (2) the extent of their assimilation achieved under these conditions.

    2009-01-01

    This study aimed to investigate the effect of mannose-binding lectin (MBL) on infections with Escherichia coli in chickens. Initially, the basic levels of MBL in 4 different lines of layer chickens, namely ISA Brown, Lohmann Selected Leghorn, Lohmann Braun, and Hellevad, were investigated....... This investigation revealed a 2-to 3-fold difference in the basic levels of MBL in serum between some of these commercial lines. Furthermore, the ontogeny of the basic level of MBL in serum of an experimental chicken line was investigated. The level of MBL was very stabile for long periods, with an elevation at 5...... to 7 wk of age. Another elevation in MBL level started around 18 to 19 wk of age and stayed elevated at least until 38 wk of age. In this study, it was hypothesized that chickens with high levels of MBL (H-type) may be less prone to disease caused by E. coli infection than chickens with low levels...

  10. Doing the Impossible George E Mueller and the Management of NASA’s Human Spaceflight Program

    CERN Document Server

    Slotkin, Arthur L

    2012-01-01

    This excellent account of one of the most important personalities in early American human spaceflight history describes for the first time how George E. Mueller, the system manager of the human spaceflight program of the 1960s, applied the SPO methodology and other special considerations, resulting in the success of the Apollo Program. While Wernher von Braun and others did not really readily accept Mueller's approach to system management, they later acknowledged that without it NASA would not have landed astronauts on the Moon by 1969. While Apollo remained Mueller's top priority, from his earliest days at the agency he promoted a robust post-Apollo program, which culminated in Skylab, the Space Shuttle, and the International Space Station. As a result of these efforts, Mueller earned the sobriquet: "the father of the Space Shuttle."

    2014-03-01

    In this work, we present a comparative study of high power diode stacks produced by world's leading manufacturers such as DILAS, Jenoptik, and Quantel. The diode-laser stacks are characterized by central wavelength around 939 nm, duty cycle of 1 %, and maximum repetition rate of 10 Hz. The characterization includes peak power, electrical-to-optical efficiency, central wavelength and full width at half maximum (FWHM) as a function of diode current and cooling temperature. A cross-check of measurements performed at HiLASE-IoP and Ferdinand-Braun-Institut (FBH) shows very good agreement between the results. Our study reveals also the presence of discontinuities in the spectra of two diode stacks. We consider the results presented here a valuable tool to optimize pump sources for ultra-high average power lasers, including laser fusion facilities.

    Full Text Available This article is resting on the theoretical model of Braun (2003 describing the delegation modes for public funding of research in the principal-agent framework. It aims to show by using the conceptualisation of utility functions of principal and agents on the various levels, how different motivations for producing different kinds of research outputs emerge for researchers and universities or public research organisations in Estonia and Ukraine. The article attempts to offer one explanation to why in some quantitative research output indicators both countries perform very well compared to much lower levels of innovation system indicators otherwise. Estonia is rewarding publications and Ukraine is rewarding utility model applications throughout different levels of the system.

    We have collaborated with two planetaria, Fernbank Science Center's Jim Cherry planetarium in Atlanta, Georgia and the Von Braun Planetarium in Huntsville, Alabama to enhance the appreciation of various astronomical topics among Girl Scouts. Major events sponsored by our partnership were sleepovers in the planetaria during which we studied the total solar eclipse of June 2001 and observed the Eta Aquarid meteor shower of May 2003. Other events included programs on stellar spectroscopy and space physics. As an added inducement for participation, we have sponsored the production of "pins", which Girl Scouts can earn after satisfying specific requirements. This poster will show samples of the pins, requirements, and online resources for the Girl Scouts.

    Freiman, Yu. A.; Hemley, R. J.; Jezowski, A.; Tretyak, S. M.

    1999-04-01

    We report the effect of the crystal field (CF) on the broken symmetry phase transition (BSP) in solid parahydrogen, orthodeuterium, and hydrogen deuteride. The CF was calculated taking into account a distortion from the ideal HCP structure. We find that, in addition to the molecular field generated by the coupling terms in the intermolecular potential, the Hamiltonian of the system contains a crystal-field term, originating from single-molecular terms in the intermolecular potential. Ignoring the CF is the main cause of the systematic underestimation of the transition pressure, characteristic of published theories of the BSP transition. The distortion of the lattice that gives rise to the negative CF in response to the applied pressure is in accord with the general Le Chatelier-Braun principle.

  19. A Generalized Evolution Criterion in Nonequilibrium Convective Systems

    Science.gov (United States)

    Ichiyanagi, Masakazu; Nisizima, Kunisuke

    1989-04-01

    A general evolution criterion, applicable to transport processes such as the conduction of heat and mass diffusion, is obtained as a direct version of the Le Chatelier-Braun principle for stationary states. The present theory is not based on any radical departure from the conventional one. The generalized theory is made determinate by proposing the balance equations for extensive thermodynamic variables which will reflect the character of convective systems under the assumption of local equilibrium. As a consequence of the introduction of source terms in the balance equations, there appear additional terms in the expression of the local entropy production, which are bilinear in terms of the intensive variables and the sources. In the present paper, we show that we can construct a dissipation function for such general cases, in which the premises of the Glansdorff-Prigogine theory are accumulated. The new dissipation function permits us to formulate a generalized evolution criterion for convective systems.

    2017-07-01

    Full Text Available The Wieprz-Krzna Canal, built in 1961, is one of the longest in Poland (142 km. Although the drainage construction was intended to revitalize the region of wetlands and peat-bogs of the West Polesie, it caused large hydrological changes. Research on catchments of three natural lakes and three retention reservoirs involved cartographic analysis using photointerpretation, as well as the Braun-Blanquet method. In the studied area, between 1939 and 2016 the length of rivers and ditches increased more than three times. Macrophytes covered about 20-27% of the natural lakes water surface, whereas in retention reservoirs the coverage was 12-15.5%. Also a greater diversity of macrophytes occurred in natural lakes. In retention reservoirs it was restricted to only emerged macrophytes.

    Bignami, Giovanni F

    2015-01-01

    In this book, Giovanni Bignami, the outstanding Italian scientist and astronomer, takes the reader on a journey through the “seven spheres”, from our own planet to neighboring stars. The author offers a gripping account of the evolution of Homo Sapiens to the stage where our species is developing capabilities, in the form of new energy propulsion systems, that will enable us to conquer space. The reader will learn how we first expanded our activities to reach beyond our planet, to the Moon, and how nuclear energy, nuclear fusion, and matter–antimatter annihilation will enable us to extend our exploration. After Mars and Jupiter we shall finally reach the nearest stars, which we now know are surrounded by numerous planets, some of which are bound to be habitable. The book includes enticing descriptions of such newly discovered planets and also brings alive key historical characters in our story, such as Jules Verne and Werner von Braun.

    In this review neutron activation analysis (NAA) and ion beam analysis (IBA) have been compared in the context of the entire field of analytical science using the discipline of scientometrics, as developed by Braun and Lyon. This perspective on the relative achievements of the two methods is modified by considering and comparing their particular attributes and characteristics, particularly in relation to their differing degree of maturity. This assessment shows that NAA, as the more mature method, is the most widely applied nuclear technique, but the special capabilities of IBA give it the ability to provide information about surface composition and elemental distribution that is unique, while it is still relatively immature and it is not yet possible to define its ultimate role with any confidence.

    2011-05-01

    Full Text Available Studies were conducted to identify a treatment method for upper layers of fly ash to cover them with vegetation. Fixing plant layer acts against erosion/washes of fly ash deposits. Studies emphasized the need of use of an organic fertilizer mixed with inorganic materials such as volcanic tuff and, also, the need of selecting a plant species compatible with the treated culture medium. The use of an amended variant of compost and modified volcanic tuff of fly ash layers shows that the selected leguminous species, Onobrychis viciifolia, installs itself quickly on the third level of Braun - Blanquet scale. The reduction of toxic heavy metals bioaccumulation from the aerial plant tissues such as lead and nickel of 72-79%, and copper and zinc of 50-68%, respectively, allows obtaining of a safe biomass for wildlife visiting the area.

Mite abundance and distribution between habitats depended on vegetation cover of the vascular plants, while moss cover and soil pH had no significant influence.

  10. Extrasolar planets and their host stars

    CERN Document Server

    von Braun, Kaspar

    2017-01-01

    This book explores the relations between physical parameters of extrasolar planets and their respective parent stars. Planetary parameters are often directly dependent upon their stellar counterparts. In addition, the star is almost always the only visible component of the system and contains most of the system mass. Consequently, the parent star heavily influences every aspect of planetary physics and astrophysics. Drs. Kaspar von Braun and Tabetha Boyajian use direct methods to characterize exoplanet host starts that minimize the number of assumptions needed to be made in the process. The book provides a background on interferometric techniques for stellar diameter measurements, illustrates the authors' approach on using additional data to fully characterize the stars, provides a comprehensive update on the current state of the field, and examines in detail a number of historically significant and well-studied exoplanetary systems.

    David, L. W.

    Early developments related to human excursions to Mars are examined, taking into account plans considered by von Braun, and the 'ambitious goal of a manned flight to Mars by the end of the century', proposed at the launch of Apollo 11. In response to public reaction, plans for manned flights to Mars in the immediate future were given up, and unmanned reconnaissance of Mars was continued. An investigation is conducted concerning the advantages of manned exploration of Mars in comparison to a study by unmanned space probes, and arguments regarding a justification for interplanetary flight to Mars are discussed. Attention is given to the possibility to consider Mars as a 'back-up' planet for preserving earth life, an international Mars expedition as a world peace project, the role of Mars in connection with resource utilization considerations, and questions of exploration ethics.

    A conference divides into sessions, but the physics does not always respect such divisions. I found the subject of barrier penetrabilities viewed in a coupled channels picture new, exciting and central to all heavy-ion reaction dynamics. The subject was discussed in bits and pieces over three different sessions, partly in the talks by Winther, Landowne, Braun-Munzinger and Broglia, and partly from the floor by the same people and by Smilanski, I have concentrated on that subject alone and I therefore must apologize to the speakers in my session who covered different material, that definitely merited further discussions. Also, I apologize to other session chairmen, whose territory I have invaded. (orig.)

    Recent experiments performed on the low β plasma device Mirabelle [T. Pierre, G. Leclert, and F. Braun, Rev. Sci. Instrum. 58, 6 (1987)] using a limiter have shown that transitions between various gradient driven instabilities occurred on increasing the magnetic field strength. New thorough measurements allow to identify unambiguously three instability regimes. At low magnetic field the strong ExB velocity shear drives a Kelvin-Helmholtz instability, whereas at high magnetic field drift waves are only observed. A centrifugal (Rayleigh-Taylor) instability is also observed in between when the ExB velocity is shearless and strong enough. A close connection is made between the ratio ρ s /L perpendicular of the drift parameter to the radial density gradient length and each instability regime

    The leading twist light-cone distributions for transversely polarized ρ-, ρ ' - and b 1 mesons are reanalyzed in the framework of QCD sum rules with nonlocal condensates. Using different kinds of sum rules to obtain reliable predictions, we estimate the 2-, 4-, 6- and 8-th moments for transversely polarized ρ- and ρ ' -meson distributions and reestimate tensor couplings f ρ,ρ ' ,b 1 T . It is stressed that the results of standard sum rules also support our estimation of the second moment of the transversely polarized ρ-meson distribution. New models for light-cone distributions are briefly discussed. Our results are compared with those found by Ball and Braun (1996), and the latter is shown to be incomplete

    1994-08-01

    Full Text Available As part of a vegetation survey programme for conservation areas in South Africa, the plant communities of the Borakalalo Nature Reserve were investigated. A TWINSPAN classification, refined by Braun-Blanquet procedures was used for a phytosociological study. The analysis resulted in five major plant communities, one with two subcommunities and one with four subcommunities and two variants. Habitat factors associated with differences in vegetation include topography, soil form and grazing pressure. Descriptions of the plant communities include diagnostic species as well as prominent and less conspicuous species of the tree, shrub, forb and grass strata. The classification provides the necessary delimitation of homogeneous areas which are considered necessary for veld management.

From a Braun-Blanquet analysis of the vegetation of the rocky outcrops and the riparian vegetation, two new orders, two new alliances and six new associations were identified and described. Additionally a quantitative assessment of the woody component of each association is presented. Ordinations based on floristic data revealed the position of the syntaxa on an environmental gradient.

    Treatment for an enterovaginal fistula should consider the location of an intestinal fistula. Most rectovaginal fistulas develop in the lower third of the vagina and can be treated surgically. Jejunovaginal fistulas can spontaneously close during conservative management. We report the first use of the Amplatzer vascular plug II (AVP II; AGA Medical Corp, Golden Valley, MN, USA) and the use of an N-butyl-2-cyanoacrylate (NBCA; Histoacryl, Braun, Melsungen, Germany)- iodized oil (Lipiodol Ultra-Fluid, Guerbet, Aulnay-sous-Bois, France) mixture for treatment of a patient with a jejunovaginal fistula which failed to close after conservative management. The patient did not have any vaginal discharge one day later after deployment of the AVP II.

    We report dose-rate information obtained at many locations in the near vicinity of, and at distances out to 0.64 km from, the Little Boy replica while it was operated as a critical assembly. The measurements were made with modified conventional dosimetry instruments that used an Anderson-Braun detector for neutrons and a Geiger-Mueller tube for gamma rays with suitable electronic modules to count particle-induced pulses. Thermoluminescent dosimetry methods provide corroborative data. Our analysis gives estimates of both neutron and gamma-ray relaxation lengths in air for comparison with earlier calculations. We also show the neutron-to-gamma-ray dose ratio as a function of distance from the replica. Current experiments and further data analysis will refine these results. 7 references, 8 figures

  4. Evaluating a nurse mentor preparation programme.

    Gray, Olivia; Brown, Donna

    Following the introduction of a regional nurse mentor preparation programme, research was undertaken within a health and social care trust to explore both the trainee mentors' and their supervisors' perception of this new programme. A qualitative study involving focus groups was undertaken. The focus groups comprised a total of twelve participants including five trainee mentors and seven supervisors (experienced mentors) who had recently completed a mentor preparation programme. Data were analysed using Braun and Clarke's thematic analysis. Three themes were identified from the data: personal investment (including the emotional impact of mentoring) contextual perceptions (environmental factors such as time) and intellectual facets (related to personal and professional growth). Comprehensive preparation for mentors appears to be effective in developing mentors with the ability to support nursing students in practice. However, further study is required to explore how to support mentors to balance the demands of the mentoring role with the delivery of patient care.

    Post-gastrectomy anastomosis site obstruction is a relatively rare complication after a subtotal gastrectomy. We present a case of a 75-year-old man who underwent a truncal vagotomy, omental patch, gastrojejunostomy, and Braun anastomosis for duodenal ulcer perforation and a gastric outlet obstruction. Following the 10(th) postoperative day, the patient complained of abdominal discomfort and vomiting. We diagnosed post-gastrectomy anastomosis site obstruction by an upper gastrointestinal series and an upper endoscopic examination. We inserted a self-expandable metallic stent (SEMS) at the anastomosis site. The stent was fully expanded after deployment. On the day following the stent insertion, the patient began to eat, and his abdominal discomfort was resolved. This paper describes the successful management of post-gastrectomy anastomosis site obstruction with temporary placement of a SEMS.

    Full Text Available One of the major plant communities identified in the Marakele National Park was forest. It became clear that this major forest community contained various forest and thicket communities. Relevés compiled in the forest were classified by TWINSPAN and Braun-Blanquet procedures identified six communities that are hierarchically classified. The forests dominated by Podocarpus latifolius and Widdringtonia nodiflora represent Afromontane Forests, whereas the Buxus macowanii-dominated dry forests and Olea europaea subsp. africana represent Northern Highveld Forests. A further group of communities represent thickets on termitaria with floristic affinities to both savanna and forest. The floristic composition and relationships of the forest and thicket communities are discussed.

    1992-01-01

    The well-known Andersson-Braun rem counter is widely employed for radiation protection purposes, but its efficiency shows a marked decrease for neutron energies above about 10 MeV. Since the availability of a survey meter with a good sensitivity to higher energies can be very useful, for instance, at many particle accelerator facilities, a neutron monitor with a response function extended up to 400 MeV has been achieved by modifying the structure of the moderator-attenuator of a commercial instrument. The first experimental tests carried out to verify the response of the new monitor both to low and high energy neutrons are reported. A comparison with the response function of three conventional commercial rem counters is presented. (author)

    1997-01-01

    This paper discusses measurements carried out at CERN in the stray radiation field produced by 158 GeV/c 208 Pb 82+ ions. The purpose was to test and intercompare the response of several detectors, mainly neutron measuring devices, and to determine the neutron spectral fluence as well as the microdosimetric (absorbed dose and dose equivalent) distributions in different locations around the shielding. Both active instruments and passive dosimeters were employed, including different types of Andersson-Braun rem counters, a tissue equivalent proportional counter, a set of superheated drop detectors, a Bonner sphere system and different types of ion chambers. Activation measurements with 12 C plastic scintillators and with 32 S pellets were also performed to assess the neutron yield of high energy lead ions interacting with a thin gold target. The results are compared with previous measurements and with measurements made during proton runs. (author)

    1990-01-01

    Extensive Monte Carlo calculations have been carried out to assess the possibility of extending the sensitivity of a neutron rem counter of the Andersson-Braun type up to several hundred MeV. The validity of the model adopted has first been checked by comparing with experimental data the calculated response curve and the angular dependence of the sensitivity for a well known commercial rem counter. Next, a number of modifications to the configuration of the moderator-attenuator have been investigated. The response functions and angular distributions produced by two simple solutions yielding an instrument with a sensitivity extended up to 400 MeV are presented. The response of the original rem counter and of its two modified versions to nine test spectra has also been calculated. The resulting instrument is transportable rather than portable, but the availability of an extended range neutron survey meter would be of great advantage at medium and high energy particle accelerator facilities.

    1983-01-01

    Human peripheral blood lymphocytes bind and take up low density lipoprotein (LDL) by receptor-mediated endocytosis. The binding of LDL was determiend by incubation with 125 I-LDL and an immunohistochemical assay. By both techniques a diminished rate of binding was found when cells were freshly isolated from the blood, but increased 5 to 10 fold when lymphocytes were incubated in lipoprotein-deficient medium for 72 hours. In addition, it was shown immunohistochemically that only few ceels showed an LDL-dependent fluorescent labelling: approximately 5 to 10 % of the freshly isolated lymphocytes and 40 to 50 % of the cells incubated for 72 hours under lipoprotein-free conditions. The present data indicate that not only the high affinity LDL receptor described by Goldstein and Braun may be involved in the uptake of cholesterol by lymphocytes, but also other binding sites, which may have immunological function in some lymphocyte subpopulations.

    The paper analyzes the "value proposition" for government-funded human space flight, a vexing question that persistently dogs efforts to justify its $10 10/year expense in the US. The original Mercury/Gemini/Apollo value proposition is not valid today. Neither was it the value proposition actually promoted by von Braun, which the post-Apollo 80% of human space flight history has persistently attempted to fulfill. Divergent potential objectives for human space flight are captured in four strategic options— Explore Mars; accelerate Space Passenger Travel; enable Space Power for Earth; and Settle the Moon—which are then analyzed for their purpose, societal myth, legacy benefits, core needs, and result as measured by the number and type of humans they would fly in space. This simple framework is proposed as a way to support productive dialog with public and other stakeholders, to determine a sustainable value proposition for human space flight.

    Full Text Available We propose a new application of quantum computing to the field of natural language processing. Ongoing work in this field attempts to incorporate grammatical structure into algorithms that compute meaning. In (Coecke, Sadrzadeh and Clark, 2010, the authors introduce such a model (the CSC model based on tensor product composition. While this algorithm has many advantages, its implementation is hampered by the large classical computational resources that it requires. In this work we show how computational shortcomings of the CSC approach could be resolved using quantum computation (possibly in addition to existing techniques for dimension reduction. We address the value of quantum RAM (Giovannetti,2008 for this model and extend an algorithm from Wiebe, Braun and Lloyd (2012 into a quantum algorithm to categorize sentences in CSC. Our new algorithm demonstrates a quadratic speedup over classical methods under certain conditions.

    Chelation therapy is an optimal method to reduce the radionuclide-related risks. In the case of uranium incorporation, the treatment of choice is so far i.v infusion of a 1.4% sodium bicarbonate solution, but the efficacy has been proved to be not very high. In this study, we examine the efficacy of some substances: bicarbonate, citrate, diethylenetriamine pentaacetic acid (DTPA), ethidronate (EHBP) and inositol hexa-phosphate (phytic acid) to chelate uranium using a test developed by Braun et al. Different concentrations of phytic acid, an abundant component of plant seeds that is widely distributed in animal cells and tissues in substantial levels, were tested and compared to the same concentrations of sodium citrate, bicarbonate, EHBP and DTPA. The results showed a strong affinity of inositol hexa-phosphate for uranium, suggesting that it could be an effective chelating agent for uranium in vivo. (authors)

  15. Space Travel is Utter Bilge: Early Ideas on Interplanetary Exploration

    Yeomans, D. K.

    2003-12-01

    Until a few decades ago, interplanetary travel was the stuff of dreams but the dreamers often turned out to be farsighted while the predictions of some eminent scientists were far too conservative. The prescient dreamers include the Russian schoolteacher, Konstanin Tsiolkovsky who, in 1883, was the first to note that only rockets could serve the needs of space travel. In 1923, Herman Oberth published a treatise discussing various aspects of interplanetary travel including the impulse necessary to escape the Earth's gravitational pull. In his spare time, a German civil engineer, Walter Hohmann, established in 1925 that the optimal energy transfer orbit between planets is an ellipse that is tangent to the orbits of both bodies. Four year later, an Austrian army officer, Hermann Potocnik outlined the benefits of space stations including those in geosynchronous orbits. Whereas Tsiolkovsky, Oberth, Hohmann, and Potocnik provided ideas and theories, the American, Robert H. Goddard, was testing liquid fueled rockets by as early as 1925. By the time he was finished in 1941, Goddard flew liquid fueled rockets that reached speeds of 700 mph and altitudes above 8,000 feet. In direct contrast to the advances by these mostly amateur engineers, many respected authorities scoffed at space travel because of the insurmountable technological difficulties. One year prior to the launch of Sputnik, the British Astronomer Royal, Sir Richard Wooley, declared, "space travel is utter bilge." While the theories of space travel were well developed by the late 1920's, space travel technology was still a poorly funded, mostly amateur, endeavor until the German army hired Oberth's student, Werner von Braun, and others to develop long range rockets for military purposes. In the early 1940's, Von Braun's team developed the rocket propulsion and guidance systems that would one day form the basis of the American space program.

    Full Text Available South Africa is well known for its semi-arid lowland areas that have a distinct flora and species composition. Because ecosystems react differently to different management practices, it is important that a description and classification of the vegetation of an area be done. As part of a vegetation survey programme for the newly acquired farms incorporated into the Mountain Zebra National Park, the vegetation of the Ingleside and Welgedacht sections were surveyed following the Braun-Blanquet approach. From a TWINSPAN classification, refined by Braun-Blanquet procedures, 10 shrub and grassland plant communities, which can be grouped into seven major groups, were identified. A classification and description of these communities, as well as a vegetation map are presented. The diagnostic species as well as the prominent and less conspicuous species of the tree, shrub, herb and grass strata are outlined. The area generally comprises lowland communities and higher-lying communities. The lower-lying communities consist mainly of two communities and comprise the largest proportion of the area in hectares. In contrast, the higher-lying communities are more diverse with specific habitats. Using the Ecological Index Method the veld condition and grazing capacity were calculated for each community and the total study area. Large sections of the lowland areas are overgrazed due to previous farming grazing practices while the higher-lying areas that were less accessible to the animals are in a slightly better condition. Overall this has resulted in the area generally being degraded within a high grazing capacity of 30.1 ha/LSU.

  17. Agrobacterium: nature's genetic engineer.

    Science.gov (United States)

    Nester, Eugene W

    2014-01-01

    Agrobacterium was identified as the agent causing the plant tumor, crown gall over 100 years ago. Since then, studies have resulted in many surprising observations. Armin Braun demonstrated that Agrobacterium infected cells had unusual nutritional properties, and that the bacterium was necessary to start the infection but not for continued tumor development. He developed the concept of a tumor inducing principle (TIP), the factor that actually caused the disease. Thirty years later the TIP was shown to be a piece of a tumor inducing (Ti) plasmid excised by an endonuclease. In the next 20 years, most of the key features of the disease were described. The single-strand DNA (T-DNA) with the endonuclease attached is transferred through a type IV secretion system into the host cell where it is likely coated and protected from nucleases by a bacterial secreted protein to form the T-complex. A nuclear localization signal in the endonuclease guides the transferred strand (T-strand), into the nucleus where it is integrated randomly into the host chromosome. Other secreted proteins likely aid in uncoating the T-complex. The T-DNA encodes enzymes of auxin, cytokinin, and opine synthesis, the latter a food source for Agrobacterium. The genes associated with T-strand formation and transfer (vir) map to the Ti plasmid and are only expressed when the bacteria are in close association with a plant. Plant signals are recognized by a two-component regulatory system which activates vir genes. Chromosomal genes with pleiotropic functions also play important roles in plant transformation. The data now explain Braun's old observations and also explain why Agrobacterium is nature's genetic engineer. Any DNA inserted between the border sequences which define the T-DNA will be transferred and integrated into host cells. Thus, Agrobacterium has become the major vector in plant genetic engineering.

    Full Text Available The objective of the proposed Highveld National Park (HNP is to conserve a considerable area of the poorly conserved Rocky Highveld Grassland and Dry Sandy Highveld Grassveld of the western Grassland Biome in South Africa. The park has not yet been proclaimed, but is currently under the management of the North West Parks and Tourism Board. The main aim of this study was to classify and describe the vegetation in the Spitskop area in the HNP. The areas affected by soil degradation were on the midslopes, footslopes, valley bottomland and the floodplains around the Spitskop hill. The concentrated grazing around the Spitskop area was also influenced by the existing dam in the floodplains. Floristic and soil degradation data were collected and used to classify and describe the plant communities of the Spitskop area. Vegetation sampling was performed by means of the Braun-Blanquet method and a total of twenty plots were sampled. A numerical classification technique (TWINSPAN was applied to the floristic data to derive a first approximation of the main plant communities. Further refinement was achieved by Braun-Blanquet procedures. The final results of the classification procedure were presented in the form of a phytosociological table, with three major communities and three subcommunities being described. Canonical correspondence analysis was used to determine the direct correlation between plant communities and soil degradation types. Soil compaction and sheet erosion were found to be the most significant variables determining plant community composition. Rill and gully erosion were shown to be of lesser significance in explaining the variation in plant communities. Conservation implications: Grasslands are amongst the most threatened biomes in South Africa, yet less than 1.3% are currently being conserved. The HNP has significant value for biodiversity conservation and the protection of this area will contribute to the preservation of the highly

    A comparison of metal needles and plastic cannulae (winged and nonwinged) for continuous subcutaneous infusion was done during a quality improvement project to reduce device-induced complications at our hospital. Design, Setting, and Measurements: Data were collected on incidence of site reactions (bruising, swelling, erythema, and blisters); mechanical complications (kinking and dislodgement); device durability; type, and volume of medications; and incidence of needle-stick injuries. All infusion devices used for patients in the Palliative Care Service from February 3 to March 26, 2014 were studied. Devices examined were: winged metal needle (Venofix(®), 23G, B. Braun Melsungen AG, Melsungen, Germany), winged vialon cannula (BD Nexiva™, 24G, Becton Dickinson Infusion Therapy Systems Inc., Sandy, UT), and nonwinged polyurethane cannula (Introcan Safety(®), 24G, B. Braun Medical, Mundelein, IL). Thirty devices (10 per type) were used. Incidence of site reactions was 50.0%, 10.0%, and 0.0% for the metal needles, polyurethane cannulae, and vialon cannulae, respectively. Incidence of mechanical complications was 20.0% for the polyurethane cannulae and 0.0% for the metal needles and vialon cannulae. Duration of use was up to 60 hours, 83 hours, and 113 hours for the metal needles, polyurethane cannulae, and vialon cannulae, respectively. Daily volumes infused were up to 28.9 mL, 60.0 mL, and 29.4 mL for the metal needles, polyurethane cannulae, and vialon cannulae, respectively. No needle-stick injuries occurred. The winged vialon cannula was the most durable, with no site reactions or mechanical complications, tolerating a volume comparable to that of the metal needle. We suggest its utilization for continuous subcutaneous infusions and consideration of future randomized controlled trials with an integrated economic evaluation for further in-depth comparisons of subcutaneous indwelling devices.

    What a grand day that was when Alan Shepard climbed into his Mercury capsule attached to a Redstone rocket-the rocket which would ultimately grow into the greatest rocket ever built, the Saturn V Moon rocket. When I was a boy in Coalwood, WV, my greatest hero, besides my father and my mother, was Huntsville's Dr. Wernher von Braun. After Sputnik was launched in October 1957, the newspapers we received in our little coal camp were filled with stories of how American scientists and engineers were desperately working to catch up in the space race. It was as if the science fiction I had read all my life was coming true. Gradually, I became fascinated by the whole thing. I read every article I could find about the men who built rockets and launched them, and kept myself pinned to the television set for the latest on what they were doing. Dr. von Braun's name was mentioned often. At night before I went to steep, I thought about what he might be doing at that very moment and imagined that he was down at Huntsville or Cape Canaveral high on a gantry, lying on his back like Michelangelo, working with a wrench on the fuel lines of one of his rockets. I started to think about what an adventure it would be to work for him, helping him to build rockets and launching them into space. For all I knew, a man with that much conviction might even form an expedition into space, like Lewis and Clark. Either way, I wanted to be part of his team.

    Full Text Available A catalogue of all named Nepticulidae and Opostegidae is presented, including fossil species. The catalogue is simultaneously published online in the scratchpad http://nepticuloidea.info/ and in Catalogue of Life (http://www.catalogueoflife.org/col/details/database/id/172. We provide a historical overview of taxonomic research on Nepticuloidea and a brief ‘state of the art’. A DNA barcode dataset with 3205 barcodes is made public at the same time, providing DNA barcodes of ca. 779 species, of which 2563 are identified as belonging to 444 validly published species. We recognise 862 extant and 18 fossil species of Nepticulidae in 22 extant genera and the fossil form genus Stigmellites. We count 192 valid Opostegidae species in 7 genera, without fossils. We also list seven dubious Nepticulidae names that cannot be placed due to absent type material and poor descriptions, 18 unavailable names in Nepticulidae that cannot be placed and we also list the 33 names (including four fossils that once were placed as Nepticulidae or Opostegidae but are now excluded. All synonyms and previous combinations are listed. The generic classification follows the Molecular phylogeny that is published almost simultaneously. Subfamilies and tribes are not recognised, Trifurculinae Scoble, 1983 is synonymised with Nepticulidae Stainton, 1854 and Opostegoidinae Kozlov, 1987 is synonymised with Opostegidae Meyrick, 1893. The status of Casanovula Hoare, 2013, Etainia Beirne, 1945, Fomoria Beirne, 1945, Glaucolepis Braun, 1917, Menurella Hoare, 2013, Muhabbetana Koçak & Kemal, 2007 and Zimmermannia Hering, 1940 is changed from subgenus to full genus, whereas two genera are considered synonyms again: Manoneura Davis, 1979, a synonym of Enteucha Meyrick, 1915 and Levarchama Beirne, 1945, a synonym of Trifurcula Zeller, 1848. We propose 87 new combinations in Nepticulidae and 10 in Opostegidae, largely due to the new classification, and re-examination of some species. We

  4. The future of naval ocean science research

    Orcutt, John A.; Brink, Kenneth

    The Ocean Studies Board (OSB) of the National Research Council reviewed the changing role of basic ocean science research in the Navy at a recent board meeting. The OSB was joined by Gerald Cann, assistant secretary of the Navy for research, development, and acquisition; Geoffrey Chesbrough, oceanographer of the Navy; Arthur Bisson, deputy assistant secretary of the Navy for antisubmarine warfare; Robert Winokur, technical director of the Office of the Oceanographer of the Navy; Bruce Robinson, director of the new science directorate at the Office of Naval Research (ONR); and Paul Gaffney, commanding officer of the Naval Research Laboratory (NRL). The past 2-3 years have brought great changes to the Navy's mission with the dissolution of the former Soviet Union and challenges presented by conflicts in newly independent states and developing nations. The new mission was recently enunciated in a white paper, “From the Sea: A New Direction for the Naval Service,” which is signed by the secretary of the Navy, the chief of naval operations, and the commandant of the Marine Corps. It departs from previous plans by proposing a heavier emphasis on amphibious operations and makes few statements about the traditional Navy mission of sea-lane control.

    Levy, David H

    2016-01-01

    In this updated second edition renowned amateur comet-searcher David H. Levy expands on his work about the intricate relationship between the night sky and the works of English Literature. This revised and expanded text includes new sections on Alfred Lord Tennyson and Gerald Manley Hopkins (both amateur astronomers), extending the time period analyzed in the first edition from early modern literature to encompass the Victorian age. Although the sky enters into much of literature through the ages, British authors offer an especially fertile connection to the heavens, and Levy links the works of seminal authors from Shakespeare on to specific celestial events and scientific advances.  From the impact of comets and supernovae to eclipses, Levy’s ultimate goal in this book is to inspire his readers to do the same thing as their ancestors did so long ago—look up and appreciate the stars. His insights in this revised book spread farther and wider than ever before in this learned and enchanting tour of the ski...

Pharmacists and the pharmacy profession have made important contributions as a part of the response to this national crisis. This article provides a brief review of the antecedents, driving forces, and health status of patients involved in the opioid medication and overdose epidemic. This review further discusses pharmacy-based actions that have been undertaken to address this issue, including prescription drug monitoring, take-back, and naloxone training/distribution programs. This review likewise examines current efforts underway in the field to educate practitioners and needed future steps that must be taken by pharmacists in order to continue the profession’s pivotal role in working toward resolving this national public health problem. In particular, evidence and arguments are presented for proactively identifying and intervening with patients who abuse and/or are at risk for overdose. Continued and active engagement by pharmacists in these efforts has the potential to result in important reductions in opioid medication abuse and overdose and improvements for patient’s health. Keywords: opioid pain medication, addiction, pharmacy practice

    Full Text Available Gerald J Mizejewski Wadsworth Center, New York State Department of Health, Albany, NY, USA Abstract: Breast cancer and Alzheimer’s disease (AD are major causes of death in older women. Interestingly, breast cancer occurs less frequently in AD patients than in the general population. Amyloidosis, the aggregation of amyloid proteins to form amyloid bodies, plays a central role in the pathogenesis of AD and other human neuropathies by forming intracellular fibrillary proteins. Contrary to popular belief, amyloidosis is a common occurrence in mammalian cells, and has recently been reported to be a natural physiological process in response to environmental stress stimulations (such as pH and temperature extremes, hypoxia, and oxidative stress. Many proteins contain an intrinsic “amyloid-converting motif”, which acts in conjunction with a specific noncoding RNA to induce formation of proteinaceous amyloid bodies that are stored in intracellular bundles. In cancer cells such as breast and prostate, the process of amyloidosis induces cells to enter a dormant or resting stage devoid of cell division and proliferation. Therefore, cancer cells undergo growth cessation and enter a dormant stage following amyloidosis in the cell; this is akin to giving the cell AD to cease growth.

  8. Howard Brenner's Legacy for Biological Transport Processes

    Nitsche, Johannes

    2014-11-01

    This talk discusses the manner in which Howard Brenner's theoretical contributions have had, and long will have, strong and direct impact on the understanding of transport processes occurring in biological systems. His early work on low Reynolds number resistance/mobility coefficients of arbitrarily shaped particles, and particles near walls and in pores, is an essential component of models of hindered diffusion through many types of membranes and tissues, and convective transport in microfluidic diagnostic systems. His seminal contributions to macrotransport (coarse-graining, homogenization) theory presaged the growing discipline of multiscale modeling. For biological systems they represent the key to infusing diffusion models of a wide variety of tissues with a sound basis in their microscopic structure and properties, often over a hierarchy of scales. Both scientific currents are illustrated within the concrete context of diffusion models of drug/chemical diffusion through the skin. This area of theory, which is key to transdermal drug development and risk assessment of chemical exposure, has benefitted very directly from Brenner's contributions. In this as in other areas, Brenner's physicochemical insight, mathematical virtuosity, drive for fully justified analysis free of ad hoc assumptions, quest for generality, and impeccable exposition, have consistently elevated the level of theoretical understanding and presentation. We close with anecdotes showing how his personal qualities and warmth helped to impart high standards of rigor to generations of grateful research students. Authors are Johannes M. Nitsche, Ludwig C. Nitsche and Gerald B. Kasting.

    1994-01-01

    A peer review was performed on a portion of the documentation of the RELAP5/MOD3 computer code. The review was performed in two phases. The first phase was a review of Vol. III, Developmental Assessment Problems, and Vol. IV, Models and Correlations. The reviewers for this phase were Dr. Peter Griffith, Dr. Yassin Hassan, Dr. Gerald S. Lellouche, Dr. Marino di Marzo and Mr. Mark Wendel. The reviewers recommended a number of improvements, including using a frozen version of the code for assessment guided by a validation plan, better discussion of discrepancies between the code and experimental data, and better justification for flow regime maps and extension of models beyond their data base. The second phase was a review of Vol. VI, Quality Assurance of Numerical Techniques in RELAP5/MOD3. The reviewers for the second phase were Mr. Mark Wendel and Dr. Paul T. Williams. Recommendations included correction of numerous grammatical and typographical errors and better justification for the use of Lax's Equivalence Theorem

    Recombinant antibody-toxins are constructed via the fusion of a 'carcinoma-specific' antibody fragment to a toxin. Due to the high affinity and high selectivity of the antibody fragments, antibody-toxins can bind to surface antigens on cancer cells and kill them without harming normal cells [L.H. Pai, J.K. Batra, D.J. FitzGerald, M.C. Willingham, I. Pastan, Anti-tumor activities of immunotoxins made of monoclonal antibody B3 and various forms of Pseudomonas exotoxin, Proc. Natl. Acad. Sci. USA 88 (1991) 3358-3362]. In this study, we constructed the antibody-toxin, Fab-SWn-PE38, with SWn (n = 3, 6, 9) sequences containing n-time repeated (G 4 S) between the Fab fragment and PE38 (38 kDa truncated form of Pseudomonas exotoxin A). The SWn sequence also harbored one cysteine residue that could form a disulfide bridge between two Fab-SWn-PE38 monomers. We assessed the cytotoxicity of the monovalent (Fab-SWn-PE38), and divalent ([Fab-SWn-PE38] 2 ) antibody-toxins. The cytotoxicity of the dimer against the CRL1739 cell line was approximately 18.8-fold higher than that of the monomer on the ng/ml scale, which was approximately 37.6-fold higher on the pM scale. These results strongly indicate that divalency provides higher cytotoxicity for an antibody-toxin.

  15. The mystery of consciousness

    1997-01-01

    It has long been one of the most fundamental problems of philosophy, and it is now, John Searle writes, "the most important problem in the biological sciences": What is consciousness? Is my inner awareness of myself something separate from my body? In what began as a series of essays in The New York Review of Books, John Searle evaluates the positions on consciousness of such well-known scientists and philosophers as Francis Crick, Gerald Edelman, Roger Penrose, Daniel Dennett, David Chalmers, and Israel Rosenfield. He challenges claims that the mind works like a computer, and that brain functions can be reproduced by computer programs. With a sharp eye for confusion and contradiction, he points out which avenues of current research are most likely to come up with a biological examination of how conscious states are caused by the brain. Only when we understand how the brain works will we solve the mystery of consciousness, and only then will we begin to understand issues ranging from artificial intelligence...

    Full Text Available The following paper has as objective questioning the legitimacy of state's paternalistic interventions on individual autonomy by using institutional-criminal instruments. In this path, the paper aims to understand in which cases the State is allowed to interfere in private individual lives under the justification of being promoting a well or avoiding a harm and, as well, in which cases such interference is abusive of individuals self-determination. Into this analysis, the work will study the current concepts of paternalism, the theoretical classifications on paternalistic interventions which will be useful to demonstrate admissible and inadmissible species of paternalism and Joel Feinberg and Gerald Dworkin's anti- paternalistic theories. Following, this subject will be analyzed in association with the implications of juridical-criminal goods involved in conflicts between autonomy, human vulnerabilities and paternalism, specially regarding to the (unavailability of those goods. In the end, the work intends to define legitimation criteria for paternalistic interventions inserted in criminal laws, which superimpose themselves on the individual autonomy, in order to harmonize constitutional values of respect for autonomy, protection of vulnerable individuals and the Criminal Law functions of exclusive protection of juridical goods.

    Full Text Available In this article memory was viewed as a crucial key to the discovery of reality. It is the basis of historical research at all levels, hence it is not confined to a function of human consciousness (brain operations: its physical vestiges are discernible in the universe, in fossils, in the DNA of species. Memory inscribes information in various ways. On a human level it is not recalled computer-wise: imagination, emotion and tacit motives play a role in how we remember. The article investigated the way in which memory underlies the operation of every cell in any living organism. Against this background the role of memory in humans and its decisive influence on every level of human life are examined. Gerald Edelman’s work in this regard was considered. Marcel Proust’s focus on memory is an underlying thread running through his novels, unrivalled in literary history. Some prominent examples were analysed in this article. In light of the foregoing the role of memory in religious experience was then discussed. The virtuality of memory is encapsulated in the statement that we remember the present whilst reliving the past. Memory characterised by virtuality is basic to our autobiographic narratives. The nature of memory determines our life stories, hence our perception of the human self as dynamically variable and open to the future.

    2015-03-01

    BBC Television's Horizon series, fifty years old on 2 May 2014, despite its significance to the history of the public culture of science, has been little studied. This microhistorical account follows the gestation and early years of the programme, demonstrating how it established a social and cultural account of science. This was a result of televisual factors, notably the determination to follow the format of the successful arts television programme Monitor. It illuminates how the processes of television production, with a handful of key participants - Aubrey Singer, Gerald Leach, Philip Daly, Gordon Rattray Taylor, Ramsay Short, Michael Peacock and Robert Reid - established the format of the programme. This occurred over seventeen months of prior preparation followed by three troubled years of seeking to establish a stable form. This was finally achieved in 1967 when the programme adopted a film documentary approach after extended attempts at making it as a studio-based magazine programme. The story has implications for understanding the social accounts of science that were circulating in the key decade of the 1960s.

    Full Text Available We made an attempt to remedy recent confusing treatments of some basic relativistic concepts and results. Following the argument presented in an earlier paper (Redžić 2008b, we discussed the misconceptions that are recurrent points in the literature devoted to teaching relativity such as: there is no change in the object in Special Relativity, illusory character of relativistic length contraction, stresses and strains induced by Lorentz contraction, and related issues. We gave several examples of the traps of everyday language that lurk in Special Relativity. To remove a possible conceptual and terminological muddle, we made a distinction between the relativistic length reduction and relativistic FitzGerald-Lorentz contraction, corresponding to a passive and an active aspect of length contraction, respectively; we pointed out that both aspects have fundamental dynamical contents. As an illustration of our considerations, we discussed briefly the Dewan-Beran-Bell spaceship paradox and the ‘pole in a barn’ paradox. [Projekat Ministarstva nauke Republike Srbije, br. 171028

    Fitzpatrick, Gerald L.

    1998-04-01

    In spite of the many successes of the standard model of particle physics, the observed proliferation of matter-fields, in the form of ``replicated'' generations or families, is a major unsolved problem. In this paper, I explore some of the algebraic, geometric and physical consequences of a new organizing principle for fundamental fermions (quarks and leptons)(Gerald L. Fitzpatrick, phThe Family Problem--New Internal Algebraic and Geometric Regularities), Nova Scientific Press, Issaquah, Washington, 1997. Read more about this book (ISBN 0--9655695--0--0) and its subject matter at: http://www.tp.umu.se/TIPTOP and/or amazon.com>http://www.amazon.com.. The essence of the new organizing principle is the idea that the standard-model concept of scalar fermion numbers f can be generalized. In particular, a ``generalized fermion number,'' which consists of a 2× 2 matrix F that ``acts'' on an internal 2-space, instead of spacetime, is taken to describe certain internal properties of fundamental fermions. This generalization automatically introduces internal degrees of freedom that ``explain,'' among other things, family replication and the number (three) of families observed in nature.

    Desmoplastic Small Round Cell Tumor (DSRCT) is a rare neoplasm of difficult diagnosis, recently described by Gerald et al. There are reports of nearly 101 cases in the literature, being the intra-abdominal region its most common location and children and young adults its preferred age group. This paper reports a case of DSRCT in a young adult of 24 years of age. This patient presented unspecific symptoms of nausea, vomiting and a single episode of haematemesis. Upon physical examination a solid mass on the epigastrium and left hypochondrium was found. Image diagnostic procedures confirmed the existence of the expansive process and also revealed enlarged retroperitoneal lymphonodes. Diagnosis was achieved through videolaparoscopic biopsy. Histologic sections stained with hematoxylin/eosin were inconclusive and immunohistochemical analysis was required to establish the diagnosis. This analysis revealed positivity to epithelial and mesenchymal markers and weak positivity to chromogranin A, characteristic results of DSRCT. Due to the fact that the disease was locally advanced, the patient was treated with chemotherapy (cyclophosphamide and paclytaxel). However, since there was only partial response to the treatment, the patient refused to undergo any second line option of therapy. Presently, the patient is being submitted only to supportive care, within an 18-month follow-up program. (author)

  4. [The neurodynamic core of consciousness and neural Darwinism].

    Science.gov (United States)

    Ibáñez, A

    In the last decades, the scientific study of consciousness in the scope of the cognitive neurosciences can be considered one of the greatest challenges of contemporary science. The Gerald Edelman theory of consciousness is one of the most promising and controversial perspectives. This theory stands out by its approach to topics usually rejected by other neurophysiologic theories of consciousness, as the case of the neurophysiologic explanation of qualia. The goal of this paper is to review the dynamic core theory of consciousness, presenting the main features of the theory, analyzing the explanation strategies, their empirical extensions, and elaborating some critical considerations about the possibility of the neuroscientific study of qualia. The central and additional theoretical components are analyzed, emphasizing its ontological, restrictive and explanatory assumptions. The properties of conscious phenomena and their cerebral correlates as advanced by the theory are described, and finally its experiments and empirical extensions are examined. The explanatory strategies of the theory are analyzed, based on conceptual isomorphism between the phenomenological properties and the neurophysiological and mathematical measures. Some criticisms could be raised about the limitations of the dynamic core theory, especially regarding its account of the so-called 'hard problem' of consciousness or qualia.

  5. Self-Ownership and Freedom: Reasons for Maintaining a Traditional Connection

    Directory of Open Access Journals (Sweden)

    Tutui Viorel

    2016-07-01

    Full Text Available Abstract: In this paper I present and analyze the classical libertarian thesis according to which there is an intimate connection between humans‟ right to self-ownership and their freedom, and I provide some reasons for preserving this traditional connection against its egalitarian contesters, represented by Gerald Allan Cohen. The principle states that humans have a right of property over their persons and powers, and any interference with this right is equivalent to a violation of their freedom. This is the reason why an egalitarian thinker like Cohen tries to reject the principle and its connection with freedom in order to legitimate redistribution of property in the benefit of the underprivileged: he argues that the principle itself (and particularly Robert Nozick‟s version of it has no special relation with freedom and lacks any real significance for political philosophy. I will reject his argumentation and evidentiate that the traditional connection still stands and the principle is indeed useful. In the last section I will formulate what I believe to be a more robust justification of it and offer some suggestions about the central role it could play in a general explanation of social and political legitimacy and normativity.

    Werner Heisenberg (centre) with Wolfgang Pauli (left) and Enrico Fermi on Lake Como, September 1927. An exhibition on the life and work of Werner Heisenberg will be on display in the Main Building (Mezzanine) at CERN from 1 - 23 July. The exhibition was produced by the University Archive of Leipzig University (Gerald Wiemers) and the Max-Planck-Institut für Physik in Munich (Helmut Rechenberg) to mark the centenary of Heisenberg's birth in 1901. German theoretical physicist Werner Karl Heisenberg (5 December 1901 - 1 February 1976) was one of the leading scientists of the 20th century. He carried out important work in nuclear and particle physics, but his most significant contribution was to the development of quantum mechanics. He is best known for his uncertainty principle, which restricts the accuracy with which some properties of atoms and particles - such as position and linear momentum - can be determined simultaneously. In 1932 he was awarded the Noble Prize in Physics 'for the creation of q...

  7. Even an old technique is suitable in the molecular world of science: the everted sac preparation turns 60 years old.

    Hamilton, Kirk L

    2014-04-15

    An old proverb states "necessity is the mother of invention." This certainly holds true in science as one pursues research questions. Experimental techniques have evolved as scientists have asked more specific research questions. Indeed, techniques such as the Ussing chamber, the perfused renal tubule preparation, patch-clamp, polymerase chain reaction, and site-directed mutagenesis have been developed over the past 60 years. However, sometimes, simple techniques may be useful and still very informative, and this certainly applies to intestinal physiology. Indeed, Gerald Wiseman and Thomas Hastings Wilson described the intestinal everted sac preparation some 60 years ago. Since then, this technique has been used for numerous research purposes including determining ion, amino acid, water and solute transport across the intestinal epithelium; and drug metabolism, absorption, and interactions in pharmaceutical/pharmacological research and even in education. This article provides a historical review of the development of the in vitro intestinal preparation that led to the everted sac preparation and its use in science.

  9. Identifying Sociological Factors for the Success of Space Exploration

    Lundquist, C. A.; Tarter, D.; Coleman, A.

    Astrosociology factors relevant to success of future space exploration may best be identified through studies of sociological circumstances of past successful explorations, such as the Apollo-Lunar Missions. These studies benefit from access to primary records of the past programs. The Archives and Special Collections Division of the Salmon Library at the University of Alabama Huntsville (UAH) houses large collections of material from the early periods of the space age. The Huntsville campus of the University of Alabama System had its birth in the mid-1950s at the time when the von Braun rocket team was relocated from Texas to Huntsville. The University, the City of Huntsville and the US Government rocket organizations developed in parallel over subsequent years. As a result, the University has a significant space heritage and focus. This is true not only for the engineering and science disciplines, but also for the social sciences. The life of the University spans the period when Huntsville government and industrial organizations were responsible for producing the rocket vehicles to first take mankind to the Moon. That endeavor was surely as significant sociologically as technologically. In the 1980s, Donald E. Tarter, conducted a series of video interviews with some leading members of the original von Braun team. Although the interviews ranged over many engineering subjects, they also recorded personal features of people involved in the Apollo lunar exploration program and the interactions between these people. Such knowledge was of course an objective. These interviews are now in the collections of the UAH Library Archives, along with extensive documentation from the same period. Under sponsorship of the Archives and the NASA-Marshall Retiree Association, the interview series was restarted in 2006 to obtain comparable oral-history interviews with more than fifty US born members of the rocket team from the 1960s. Again these video interviews are rich with

  12. How Simultaneous is the Perception of Binocular Depth and Rivalry in Plaid Stimuli?

    2012-06-01

    Full Text Available Psychophysical experiments have demonstrated that it is possible to perceive both binocular depth and rivalry in plaids (Buckthought and Wilson 2007, Vision Research 47 2543–2556. In a recent study, we investigated the neural substrates for depth and rivalry processing with these plaid patterns, when either a depth or rivalry task was performed (Buckthought and Mendola 2011, Journal of Vision 11 1–15. However, the extent to which perception of the two stimulus aspects was truly simultaneous remained somewhat unclear. In the present study, we introduced a new task in which subjects were instructed to perform both depth and rivalry tasks concurrently. Subjects were clearly able to perform both tasks at the same time, but with a modest, symmetric drop in performance when compared to either task carried out alone. Subjects were also able to raise performance levels for either task by performing it with a higher priority, with a decline in performance for the other task. The symmetric declines in performance are consistent with the interpretation that the two tasks are equally demanding of attention (Braun and Julesz 1998, Perception & Psychophysics 60 1–23. The results demonstrate the impressive combination of binocular features that supports coincident depth and rivalry in surface perception, within the constraints of presumed orientation and spatial frequency channels.

    Full Text Available This study on the natural and degraded natural vegetation of natural areas in the Potchefstroom Municipal Area, forms part of a research programme on spontaneous vegetation in urban open spaces in the North West Province, South Africa. Using a numerical classification technique (TWINSPAN as a first approximation, the classification was refined by applying Braun-Blanquet procedures. The result is a phytosociological table from which 6 plant communities were recognised, which are subdivided in sub-communities and variants, resulting in 18 vegetation units. Some of these vegetation units are similar to communities described previously in natural areas. The presence of degraded natural communities suggests huge anthropogenic influences in certain areas. An ordination (DECORANA scatter diagram shows the distribution of the plant communities along gradients which could be related to vegetation structure, altitude, soil depth, rockiness of soil surface, wetness or dryness of the habitat and number of introduced species. This study contributes to the compilation of a guideline for a conservation orientated management plan for the area, but also created a wealth of new knowledge of the reaction of indigenous plant species under disturbed conditions.

    L.G. Ramensky (1884-1953) was an outstanding Soviet geobotanist of the first part of XX century. Considered is his theoretical legacy and its contribution to modern vegetation science. L.G. Ramensky formulated the principle of vegetation continuum based on which the modern paradigm of vegetation science has been put into shape. The scientist made a contribution to the development of such important theoretical conceptions as types of plant strategy, coenosis and coenobiosis (coexistence of species), patterns of interannual variability in plant communities, ecological successions. The unique ecological scales were established by L.G. Ramensky that characterize the distribution of 1400 species over the gradients of soil moistening, richness, and salinization as well as moistening variability, pastoral digression, and alluvial intensity. He came out against mechanistic notions by V.N. Sukachev on a biogeocoenosis structure. The scientist did not offer his own method of plant communities classification but his well-reasoned criticism of dominant classification played a great role in adoption of floristical classification principles (Braun-Blanquet approach) by phytocenology in our country.

    The aim of this study was to explore intensive care nursing students experiences with confirming communication skills training in a simulation-based environment. The study has a qualitative, exploratory and descriptive design. The participants were students in a post-graduate program in intensive care nursing, that had attended a one day confirming communication course. Three focus group interviews lasting between 60 and 80min were conducted with 14 participants. The interviews were transcribed verbatim. Thematic analysis was performed, using Braun & Clark's seven steps. The analysis resulted in three main themes: "awareness", "ice-breaker" and "challenging learning environment". The participants felt that it was a challenge to see themselves on the video-recordings afterwards, however receiving feedback resulted in better self-confidence in mastering complex communication. The main finding of the study is that the students reported improved communication skills after the confirming communication course. However; it is uncertain how these skills can be transferred to clinical practice improving patient outcomes. Copyright © 2017 Elsevier Ltd. All rights reserved.

[Cyano- 11 C]benzonitriles were prepared using the Rosenmund-von Braun reaction in one step from [ 11 C]hydrogen cyanide via [ 11 C]copper(1) cyanide in 2 min. [Carboxyl- 11 C]benzoic acids and [carbonyl- 11 C]benzamides were prepared from [cyano- 11 C]benzonitrile-complexes using basic hydrogen peroxide for 3 min in N,N-dimethylformamide at 180 and 80 o C, respectively. [Tetrazoyl- 11 C]5-biphenyl-1H-tetrazoles were obtained from [cyano- 11 C]benzonitrile-complexes in 7 min by cyclization with trimethyltin azide followed by acid hydrolysis at 180 o C. These labelled compounds were obtained in a one-pot procedure with good average specific radioactivities [500 mCi/μmol) at the end of synthesis] and in satisfactory average radiochemical yields (24-69%) at 40 min from the end of radionuclide production. This new radioactive precursor, [ 11 C]copper(I) cyanide, should give access to new 11 C-labelled ligands for positron emission tomography. (author)

    Participation in the Paralympic Games has grown substantially, yet the same growth and development has not occurred with empirical literature for coaching in disability sport. The purpose of the current study was to explore Paralympic coaches' perceptions of their learning and educational experiences, including their formal and informal mentoring opportunities. Six highly successful and experienced Paralympic coaches were individually interviewed in this qualitative study. The interview data were analyzed following Braun and Clarke's guidelines for thematic analysis. Results demonstrated that Paralympic coaches faced several challenges to acquire disability specific coaching knowledge and skills. These challenges led the participants to utilize an array of informal learning situations, such as actively seeking mentoring relationships when they first entered the field. After becoming expert coaches, they gave back to their sport by making mentoring opportunities available for aspiring coaches. The results of the current study address the value and importance of mentoring as a structured source of education and career development for aspiring Paralympic coaches. Crown Copyright © 2016.

    Although pediatric palliative care policies and services have been developed, research in this area continues to lag. An integrated model of palliative care has been suggested by the American Academy of Pediatrics and includes complementary and alternative services aimed at improving the well-being of children and their families. The first-known pediatric palliative aquatics program (PPAP) in California uses several techniques to decrease pain and promote well-being through relaxation and interaction between patients, specialists, and family members. This study investigates the perceptions of family members of their children's experiences with a PPAP. Researchers from an outside institution conducted focus groups and interviews. Themes were extracted from the focus group transcripts using Braun and Clarke's method of inductive thematic analysis. Data were collected at the host site, local libraries, and participant homes. Participants were primary caregivers and siblings (n = 23) of children in a PPAP, an independent children's respite, transitional, and end-of-life care facility in California. The research described and drew implications from the diverse perceptions that family members expressed about the benefits of having a child in the PPAP, including sensory, physical, and social experiences. Although the PPAP aims to promote well-being through relaxation, several other benefits were expressed by family members of children going through the program, including pain relief.

    Astaxanthin has been shown to have antiproliferative activity on breast cancer and skin cancer cells. However, the high cost of production, isolation and purification of purified astaxanthin from natural sources or chemically synthetic methods limit its usage on cancer therapy. We show that astaxanthin could be produced by fermentating the Phaffia rhodozyma (Xanthophyllomyces dendrorhous) yeast cells with brewer malt waste using a 20 L B. Braun fermentor. The percentage composition of astaxanthin from the P. rhodozyma was >70% of total pigment as estimated by the high performance liquid chromatographic analysis. Furthermore, the antiproliferative activity of this P. rhodozyma cell extract (PRE) was demonstrated on breast cancer cell lines including the MCF-7 (estrogen receptor positive) and MDA-MB231 (estrogen receptor negative) by using the [3-(4,5-dimethylthiazol-2-yl)-5-(3-arboxymethoxyphenyl)-2- (4-sulfophenyl)-2H-tetrazolium] (MTS) assay. No apoptotic cell death, but growth inhibitory effect was induced after 48 h of PRE incubation as suggested by morphological investigation. Anchorage-dependent clonogenicity assay showed that PRE could reduce the colony formation potential of both breast cancer cell lines. Cell death was observed from both breast cancer cell lines after incubation with PRE for 6 days. Taken together, our results showed that by using an economic method of brewer malt waste fermentation, we obtained P. rhodozyma with a high yield of astaxanthin and the corresponding PRE could have short-term growth inhibition and long-term cell death activity on breast cancer cells.

    Full Text Available Childhood obesity is a major concern in today's society. Research suggests the inclusion of the views and understandings of a target group facilitates strategies that have better efficacy. The objective of this study was to explore the concepts and themes that make up children's understandings of the causes and consequences of obesity. Participants were selected from Reception (4–5 years old and Year 6 (10–11 years old, and attended a school in an area of Sunderland, in North East England. Participants were separated according to age and gender, resulting in four focus groups, run across two sessions. A thematic analysis (Braun & Clarke, 2006 identified overarching themes evident across all groups, suggesting the key concepts that contribute to children's understandings of obesity are “Knowledge through Education,” “Role Models,” “Fat is Bad,” and “Mixed Messages.” The implications of these findings and considerations of the methodology are discussed in full.

    2004-12-01

    Full Text Available The Kammanassie Mountain is a declared mountain catchment area and a Cape mountain zebra Equus zebra zebra population is preserved on the mountain. The high number of springs on the mountain not only provides water for the animal species but also contributes to overall ecosystem functioning. Long-term conservation of viable ecosystems requires a broader understanding of the ecological processes involved. It was therefore decided that a classification, description and mapping of the spring vegetation of the Kammanassie Mountain be undertaken. A TWINSPAN classification, refined by Braun-Blanquet procedures, revealed 11 major plant communities that could be related to geological origin. Habitat factors associated with differences in vegetation include topography, soil type and grazing. Descriptions of the plant communities include diagnostic species as well as prominent and less conspicuous species of the tree, shrub and herbaceous layers. The results also indicate a high species richness compared to similar regions and the difference between plant communities of wet and dry springs. This data is important for long-term monitoring of the spring ecosystems as well as for the compilation of management plans.

    Full Text Available ABSTRACT A phytosociological approach to dry forest and cactus communities on the occidental slopes of the Peruvian Andes is presented in base of 164 plots carried out following the Braun-Blanquet method. From them, 52 have been made recently, and the other 112 were taken from the literature. After a multivariate analysis, using a hierarchical clustering and a detendred correspondence analysis, the Acacio-Prosopidetea class (dry forest and cactus communities, developed on soils with some edaphic humidity or precipitations derived from El Niño Current, the Opuntietea sphaericae class (cactus communities of central and southern Peru, on few stabilized rocky or sandy soils and the Carico-Caesalpinietea class (dry forests of the Peruvian coastal desert, influenced by the maritime humidity of the cold Humboldt Current, are differentiated. Within the Acacio-Prosopidetea class, two alliances are commented: the Bursero-Prosopidion pallidae (with two new associations Loxopterygio huasanginis-Neoraimondietum arequipensis and Crotono ruiziani-Acacietum macracanthae, and the new alliance Baccharido-Jacarandion acutifoliae (with the new associations Armatocereo balsasensis-Cercidietum praecocis and Diplopterydo leiocarpae-Acacietum macracanthae. For the Opuntietea sphaericae class, the association Haageocereo versicoloris-Armatocereetum proceri (Espostoo-Neoraimondion is described on the basis of plots from hyperarid localities of central Peru. Finally, a typological classification of the studied plant communities is given.

    Leveraging funds from NASA's Initiative to Develop Education through Astronomy and Space Science (IDEAS) program, we combined the expertise of an archaeoastronomer, a solar scientist, and a teacher to trace humankind's view of the Sun and how that has changed, from the time of Stonehenge in about 1800 B.C.E., to the time of the Maya in 700 C.E., up to the modem era. Our program was aimed at middle-school students in an attempt to explain not only how science is done today, but how science has evolved from the observations of ancient societies. From these varied cultures, we touched on methods of observing the Sun, ideas of the composition of the Sun, and the relationship of the Sun to everyday life. Further, using the von Braun Astronomical Society's Planetarium in Huntsville, Alabama as a test-bed for the program, we illustrated concepts such as solstices, equinoxes, and local noon with approximately 800 eighth grade students from the local area. Our presentation to SEPA will include a description of NASA's IDEAS program and how to go about partnering with a NASA astronomer, some slides from our planetarium program and web-site, and some hands-on activities.

    Blended learning has become the method of choice in educational institutions because of its systematic integration of traditional classroom teaching and online components. This study aims to analyze student's reflection regarding blended learning in dental pharmacology. A cross-sectional study was conducted in Faculty of Dentistry, Melaka-Manipal Medical College among 3 rd and 4 th year BDS students. A total of 145 dental students, who consented, participate in the study. Students were divided into 14 groups. Nine online sessions followed by nine face-to-face discussions were held. Each session addressed topics related to oral lesions and orofacial pain with pharmacological applications. After each week, students were asked to reflect on blended learning. On completion of 9 weeks, reflections were collected and analyzed. Qualitative analysis was done using thematic analysis model suggested by Braun and Clarke. The four main themes were identified, namely, merits of blended learning, skill in writing prescription for oral diseases, dosages of drugs, and identification of strengths and weakness. In general, the participants had a positive feedback regarding blended learning. Students felt more confident in drug selection and prescription writing. They could recollect the doses better after the online and face-to-face sessions. Most interestingly, the students reflected that they are able to identify their strength and weakness after the blended learning sessions. Blended learning module was successfully implemented for reinforcing dental pharmacology. The results obtained in this study enable us to plan future comparative studies to know the effectiveness of blended learning in dental pharmacology.

  8. Diving behavior of the reef manta ray links coral reefs with adjacent deep pelagic habitats

    2014-02-06

    Recent successful efforts to increase protection for manta rays has highlighted the lack of basic ecological information, including vertical and horizontal movement patterns, available for these species. We deployed pop-up satellite archival transmitting tags on nine reef manta rays, Manta alfredi, to determine diving behaviors and vertical habitat use. Transmitted and archived data were obtained from seven tagged mantas over deployment periods of 102-188 days, including three recovered tags containing 2.6 million depth, temperature, and light level data points collected every 10 or 15 seconds. Mantas frequented the upper 10 m during daylight hours and tended to occupy deeper water throughout the night. Six of the seven individuals performed a cumulative 76 deep dives (>150 m) with one individual reaching 432 m, extending the known depth range of this coastal, reef-oriented species and confirming its role as an ecological link between epipelagic and mesopelagic habitats. Mean vertical velocities calculated from high-resolution dive data (62 dives >150 m) from three individuals suggested that mantas may use gliding behavior during travel and that this behavior may prove more efficient than continuous horizontal swimming. The behaviors in this study indicate manta rays provide a previously unknown link between the epi- and mesopelagic layers of an extremely oligotrophic marine environment and provide evidence of a third marine species that utilizes gliding to maximize movement efficiency. © 2014 Braun et al.

    Although social relationships and social support are salient factors for post-war adolescents' psychosocial coping and adjustment, there is only limited information regarding war-affected adolescents' views on social support and the relationships within which social support is provided. This study therefore explored both elements among a clinical sample of 20 adolescents living in post-war Northern Uganda. Following Braun and Clarke's thematic analysis, we found a prominent role of the biological mother and other primary biological family members in the upbringing of our participants. Spiritual and material support were perceived to be the most important type of support, respectively, while the adolescents were growing up and in their current lives. These findings provide support for the perception that caregiving systems are adaptable to particular sociocultural contexts. Further, the importance of particular functions of social support could signify a potentially selective buffering effect of these functions in adverse contexts. Because of the importance of the primary biological family and the salient role of parent-child relationships in the face of adversity, future research needs to focus on this particular kind of social relationship in contexts of prolonged collective violence. © 2015 International Union of Psychological Science.

  10. Outline on 'reactive separation, why now'. Gairon 'naze ima, hanno bunri ka'

    This paper describes mainly a reactive separation membrane reactor, introducing its principle, history, membrane materials, and permeation mechanism. When a product is removed out of a system, the equilibrium shifts to the product side according to the law of Le Chatelier-Braun. The reaction invert ratio in this case can be explained with an idea that it is based on the equilibrium theory and the velocity theory. Simulations are also performed using numerical analyses. Historically, studies had been made in the 1980{prime}s on reaction velocity theory, permeation mechanisms, and engineering approaches. Reactions as the object of the studies were focused mainly on dehydrogenation react ion. Thereafter, studies have begun on permeation of substances with new membrane other than hydrogen and on biological field. Membrane materials used then were heat-resistant and chemically stable inorganic materials. Recent reports include polymer membranes, hydrophilic and hydrophobic Membrane (in biological field), liquid membranes, and composite membranes. Separation membranes may be divided largely into porous membranes (with micro ports ranging from several {angstrom} to several hundred {angstrom} )and non-porous membranes, each having its specific permeation mechanism. 9 refs., 3 figs., 2 tabs.

  11. Backward jump continuous-time random walk: An application to market trading

    2010-10-01

    The backward jump modification of the continuous-time random walk model or the version of the model driven by the negative feedback was herein derived for spatiotemporal continuum in the context of a share price evolution on a stock exchange. In the frame of the model, we described stochastic evolution of a typical share price on a stock exchange with a moderate liquidity within a high-frequency time scale. The model was validated by satisfactory agreement of the theoretical velocity autocorrelation function with its empirical counterpart obtained for the continuous quotation. This agreement is mainly a result of a sharp backward correlation found and considered in this article. This correlation is a reminiscence of such a bid-ask bounce phenomenon where backward price jump has the same or almost the same length as preceding jump. We suggested that this correlation dominated the dynamics of the stock market with moderate liquidity. Although assumptions of the model were inspired by the market high-frequency empirical data, its potential applications extend beyond the financial market, for instance, to the field covered by the Le Chatelier-Braun principle of contrariness.

  12. Identifying the adaptive mechanism in globular proteins: Fluctuations in densely packed regions manipulate flexible parts

    A low-resolution structural model based on the packing geometry of α-carbons is utilized to establish a connection between the flexible and rigid parts of a folded protein. The former commonly recognizes a complementing molecule for making a complex, while the latter manipulates the necessary conformational change for binding. We attempt analytically to distinguish this control architecture that intrinsically exists in globular proteins. First with two-dimensional simple models, then for a native protein, bovine pancreatic trypsin inhibitor, we explicitly demonstrate that inserting fluctuations in tertiary contacts supported by the stable core, one can regulate the displacement of residues on loop regions. The positional fluctuations of the flexible regions are annihilated by the rest of the protein in conformity with the Le Chatelier-Braun principle. The results indicate that the distortion of the principal nonbonded contacts between highly packed residues is accompanied by that of the slavery fluctuations that are widely distributed over the native structure. These positional arrangements do not appear in a reciprocal relation between a perturbation and the associated response; the effect of a movement of residue i on residue j is not equal to that of the same movement of residue j on residue i.

    Power toothbrushes (PTBs), in combination with abrasive dentifrices, may encourage wear of dental cements at crown margins. The objective of this in vitro simulation was to control the clinical variables associated with PTB use and measure the potential side effects of PTBs with mild and abrasive dentifrices. Four PTBs ( Braun-Oral-B-Professional Care at 150 g brushing force, Sonicare-Elite at 90 g, Colgate-Actibrush at 200 g and Crest-Spinbrush-Pro at 250 g) and 2 dentifrices mixed 1:1 with tap water (Mild= Colgate-Total, Colgate-Palmolive; Abrasive= Close-up, Chesebrough-Ponds) versus tap water alone (control) were used to abrade 2 cements (Fleck's Mizzy Zinc Phosphate [ZP]; 3M-ESPE Unicem universal cement [UC]) using cement-filled slots (160 m wide) cut into wear-resistant ceramic blocks. A custom fixture controlled PTB/block alignment, PTB loads, and other testing variables. Wear was measured (3 profilometer traces/slot, 5 slots/block/group, baseline to 5-year differences) and analyzed (3-way ANOVA, p PTBs and both dentifrices. Brushing with water showed no effects (pPTBs. Pooled 5y-wear levels for ZP for both dentifrices approximately 21 microm /5y) were similar to values for current-day posterior composite materials. Combinations of PTBs with mild and abrasive dentifrices produced significant wear with ZP but not UC; thus, resin-composite cements seem to represent a better choice for wear resistance.

    Full Text Available The plant communities of the Blydeberg Conservancy were investigated as part of a research project on the foraging ecology of vervet monkeys Cercopithecus aethiops pygerythrus (senso lato in mixed lowveld bushveld and sour lowveld bushveld areas. To date there are no formal management plans for vervet monkeys. This is attributed to the limited knowledge of vervets and their utilisation of and impacts on ecosystems. From a TWINSPAN classification refined by Braun-Blanquet procedures, ten plant communities that can be placed into four major groups were identified. A classification and description of these communities, including a vegetation map are presented. Diagnostic species as well as prominent and less conspicuous species of tree, shrub, herb and grass strata are outlined. Of the ten available plant communities, the vervets utilised only six during the study period. There was an abundant supply of various food sources throughout the year, with movement patterns mostly coinciding with the fruiting times of several tree and other plant species.

  15. Vegetation of the coastal fynbos and rocky headlands south of George, South Africa

    Full Text Available Community structure and composition of the coastal fynbos and rocky headland plant communities south of George, southern Cape, were studied. Vegetation was analysed using standard sampling procedures of the floristic-sociological approach of Braun-Blanquet. The releve data were subject to TWIN SPAN-based divisive classification, and ordinated by Principal Coordinates Analysis with the aim to identify vegetation coenocline subsequently interpreted in terms of under­lying environmental gradients. Most of the sampled vegetation was classified as coastal fynbos. The  Leucadendron salignum-Tetraria cuspidata Fynbos Community was found to occupy sheltered habitats, whereas the  Relhania calyci- na-Passerina vulgaris Fynbos Community was found in exposed habitats The other two communities characterise strong­ly exposed rocky headlands. The Pterocelastrus tricuspidatus-Ruschia tenella Community is wind-sheared scrub, and the Gazania rigens- Limonium scabrum Rocky Headland Community is a loose-canopy, low-grown herbland, characterised by the occurrence of partly salt-tolerant and succulent herbs. The ordination of the fynbos communities revealed a horseshoe structure allowing a direct recognition of a coenocline spanning two fynbos communities along the Axis 1 interpreted in terms of exposure to wind and salt spray. A considerable amount of alien plant infestation was also present. This appears to be the largest threat to the continued existence of this coastal fynbos.

    In this study, phytosociological survey using Braun-Blanquet's approach was undertaken to investigate the Hudiara drain wastewater influence on the surrounding vegetation. A total of 99 quadrats were laid to identify the plant species and altogether 66 species were recorded. Multivariate analysis of vegetation data (using CANOCO 4.5. software) classified the vegetation into two major communities including Cynodon dactylon, Boerhaavia diffusa, Parthenium hysterphorus and Xanthium strumarium groups. The presence of these species designated the area as waste land strongly supporting the growth of such species. The pattern of floral diversity was also not uniform and exhibited considerable variation. Canonical Correspondence Analysis revealed that the distribution of vegetation has correlation with environmental variables, but their role in the grouping of species remained non significant. However, soil EC played some role in the grouping of Stellaria media and Fagonia cretic. Similarly, some species viz., Ricinus communis, Boerhaavia diffusa and Phragmites karka showed a correlation with Fe and Cr respectively, suggesting Phragmites karka as a suitable candidate for chromium contaminated sites.

    Following positive results obtained in in vitro studies and in vivo implantations in animals, a clinical trial using the Vascugraft polyurethane arterial prosthesis as a below-knee substitute was undertaken in 15 patients. Eight grafts became occluded during the first year, and segments from four of them were explanted and made available for pathological, structural and chemical investigations. The implantation periods ranged from 21 to 358 days. Failures were associated with kinking (one case), possible anastomotic mismatch between the graft and the artery (one case), and poor run-off (two cases). No organized collagenous internal encapsulation was noted; however, endothelial-like cells were observed at the anastomotic site of one graft. No significant structural degradation of the prostheses was observed in those grafts implanted for 21, 38 and 46 days. Some deteriorations in the fibrous structure were observed on the external surface of the prosthesis implanted for 358 days. High-resolution carbon C1s analysis by ESCA demonstrated a 60 to 80% decrease in carbonate content on the surface of all explanted prostheses. Chemical analyses of each polyurethane graft by IR, SEC and DSC revealed no significant chemical changes. The clinical performance of the Vascugraft prosthesis for below-knee implantation proved to be no more impressive than that of expanded polytetrafluorethylene, the currently accepted reference. The decision by B. Braun Melsungen AG to end this program is therefore to be regarded as highly professional.

    In this study, ZnO nanoparticles (ZNP) of approximately 30 nm in size were synthesized by the hydrothermal method and characterized by X-ray diffraction (XRD), Braun-Emmet-Teller (BET) N2 adsorption analysis and transmission electron microscopy (TEM). ZnO nanoparticles enriched with poly(vinylferrocenium) (PVF+) modified single-use graphite electrodes were then developed for the electrochemical monitoring of nucleic acid hybridization related to the Hepatitis B Virus (HBV). Firstly, the surfaces of polymer modified and polymer-ZnO nanoparticle modified single-use pencil graphite electrodes (PGEs) were characterized using scanning electron microscopy (SEM). The electrochemical behavior of these electrodes was also investigated using differential pulse voltammetry (DPV) and electrochemical impedance spectroscopy (EIS). Subsequently, the polymer-ZnO nanoparticle modified PGEs were evaluated for the electrochemical detection of DNA based on the changes at the guanine oxidation signals. Various modifications in DNA oligonucleotides and probe concentrations were examined in order to optimize the electrochemical signals that were generated by means of nucleic acid hybridization. After the optimization studies, the sequence-selective DNA hybridization was investigated in the case of a complementary amino linked probe (target), or noncomplementary (NC) sequences, or target and mismatch (MM) mixture in the ratio of (1:1).

    The Poços de Caldas Plateau in the southeastern Brazil, and it is characterized by a high relief topography supported by the pre-Cambrian crystalline rocks and by the Poços de Caldas Alkaline Massif (PCAM). Ulbrich et al (2002) determine that the ages for the predominant PCAM intermediate rocks were constrained ~83Ma. In addition, geologic observations indicates the phonolites, tinguaites and nepheline syenites were emplaced in a continuous and rapid sequence lasting between 1 to 2 Ma. The topography is characterized by dissected plateau with irregular topographic ridges and peaks with elevations between 900 and 1300m (a.s.l.) on the metamorphic basement and from 1300 to 1700m (a.s.l) on the PCAM region. Therefore, the aim of the work was quantify the main processes that were responsible for the evolution of the landscape by using methods as the low temperature thermochronology and the 3D thermokinematic modeling, for obtaining data of uplift and erosion rates and to correlate them with the thermal gradients of the region. The 3D thermokinematic modeling was obtained using the software code PECUBE (Braun 2003).

    Several studies over the past few decades have recognized the need for advanced propulsion to explore the solar system. As early as the 1960s, Werner Von Braun and others recognized the need for a nuclear rocket for sending humans to Mars. The great distances, the intense radiation levels, and the physiological response to zero-gravity all supported the concept of using a nuclear rocket to decrease mission time. These same needs have been recognized in later studies, especially in the Space Exploration Initiative in 1989. One of the key questions that has arisen in later studies, however, is the ability to test a nuclear rocket engine in the current societal environment. Unlike the Rover/NERVA programs in the 1960s, the rocket exhaust can no longer be vented to the open atmosphere. As a consequence, previous studies have examined the feasibility of building a large-scale version of the Nuclear Furnace Scrubber that was demonstrated in 1971. We have investigated an alternative that would deposit the rocket exhaust along with any entrained fission products directly into the ground. The Subsurface Active Filtering of Exhaust, or SAFE, concept would allow variable sized engines to be tested for long times at a modest expense. A system overview, results of preliminary calculations, and cost estimates of proof of concept demonstrations are presented. The results indicate that a nuclear rocket could be tested at the Nevada Test Site for under $20 M

    In a planetarium, the visitor is sitting on Earth and looking into an imaginary space. The Planetarium Inversum is the opposite: visitors are sitting in a space station, looking down on Mother Earth. It is a scientifically-based information show with visitors involvement, its elements being partially virtual (Earth in space has to be projected with highest possible resolution) but also containing real structures, such as the visitors' Earth observatory with adjacent biological systems (plant cultures and other ecological life support components). Its main message concerns the limits and the vulnerability of our home planet, its uniqueness, beauty and above all, its irreplaceableness: Earth does not have an emergency exit. The Earth observatory is part of a ring shaped, rotating space station of the type designed by Wernher von Braun decades ago. Visitors are told that gravity is being substituted by centrifugal force. Both types of life support systems are being demonstrated--self regenerative life based ones and technical ones as a backup (solar electric splitting of water and chemical absorption of respiratory CO2). c2003 COSPAR.

    Bipolar disorder (BD) is a chronic and recurrent affective disorder. Recovery is defined as the process by which people can live fulfilling lives despite experiencing symptoms. To explore how an opportunistically recruited group of service users with BD experience recovery and self-management to understand more about how a service users' recovery may be supported. Twelve service users with BD took part in a series of focus groups. Service users' responses to questions about their personal experiences of self-management and recovery were analysed. Focus groups were transcribed verbatim and thematic analysis ([ Braun, V., & Clarke, V. (2006). Using thematic analysis in psychology. Qualitative Research in Psychology, 3(2), 77-101]) was employed to identify common themes in the data. Four key themes were identified: (1) Recovery is not about being symptom free; (2) Recovery requires taking responsibility for your own wellness; (3) Self-management: building on existing techniques; (4) Overcoming barriers to recovery: negativity, stigma and taboo. Service users with BD have provided further support for the concept of recovery and have suggested a number of ways recovery can be supported. A self-management approach informed by the recovery literature has been proposed as a way to support service users' recovery.

    In this paper, we study the dynamics of the Bose-Hubbard model by using time-dependent Gutzwiller methods. In particular, we vary the parameters in the Hamiltonian as a function of time, and investigate the temporal behavior of the system from the Mott insulator to the superfluid (SF) crossing a second-order phase transition. We first solve a time-dependent Schrödinger equation for the experimental setup recently done by Braun et al. [Proc. Natl. Acad. Sci. USA 112, 3641 (2015)] and show that the numerical and experimental results are in fairly good agreement. However, these results disagree with the Kibble-Zurek scaling. From our numerical study, we reveal a possible source of the discrepancy. Next, we calculate the critical exponents of the correlation length and vortex density in addition to the SF order parameter for a Kibble-Zurek protocol. We show that beside the "freeze" time t ̂, there exists another important time, teq, at which an oscillating behavior of the SF amplitude starts. From calculations of the exponents of the correlation length and vortex density with respect to a quench time τQ, we obtain a physical picture of a coarsening process. Finally, we study how the system evolves after the quench. We give a global picture of dynamics of the Bose-Hubbard model.

    Ethiopian mustard (Brassica carinata A. Braun) line BCT-6, with reduced γ-tocopherol content in the seeds, has been previously developed. The objective of this research was to conduct a genetic analysis of seed tocopherols in this line. BCT-6 was crossed with the conventional line C-101 and the F1, F2, and BC plant generations were analyzed. Generation mean analysis using individual scaling tests indicated that reduced γ-tocopherol content fitted an additive-dominant genetic model with predominance of additive effects and absence of epistatic interactions. This was confirmed through a joint scaling test and additional testing of the goodness of fit of the model. Conversely, epistatic interactions were identified for total tocopherol content. Estimation of the minimum number of genes suggested that both γ- and total tocopherol content may be controlled by two genes. A positive correlation between total tocopherol content and the proportion of γ-tocopherol was identified in the F2 generation. Additional research on the feasibility of developing germplasm with high tocopherol content and reduced concentration of γ-tocopherol is required.

    A phytosociological approach to dry forest and cactus communities on the occidental slopes of the Peruvian Andes is presented in base of 164 plots carried out following the Braun-Blanquet method. From them, 52 have been made recently, and the other 112 were taken from the literature. After a multivariate analysis, using a hierarchical clustering and a detendred correspondence analysis, the Acacio-Prosopidetea class (dry forest and cactus communities, developed on soils with some edaphic humidity or precipitations derived from El Niño Current), the Opuntietea sphaericae class (cactus communities of central and southern Peru, on few stabilized rocky or sandy soils) and the Carico-Caesalpinietea class (dry forests of the Peruvian coastal desert, influenced by the maritime humidity of the cold Humboldt Current), are differentiated. Within the Acacio-Prosopidetea class, two alliances are commented: the Bursero-Prosopidion pallidae (with two new associations Loxopterygio huasanginis-Neoraimondietum arequipensis and Crotono ruiziani-Acacietum macracanthae), and the new alliance Baccharido-Jacarandion acutifoliae (with the new associations Armatocereo balsasensis-Cercidietum praecocis and Diplopterydo leiocarpae-Acacietum macracanthae). For the Opuntietea sphaericae class, the association Haageocereo versicoloris-Armatocereetum proceri (Espostoo-Neoraimondion) is described on the basis of plots from hyperarid localities of central Peru. Finally, a typological classification of the studied plant communities is given.

  7. Study of the chemical binding effect on the molecular stopping power of V2O5

    1981-01-01

    The stopping powers of V and V 2 O 5 have been measured for helium ions with energies from 0.3 to 2.0 MeV and probable errors of 2.2 and 3.0%, respectively. The vanadium stopping power was 12 and 14% lower than the previous measurement of Chu and Powers (1969) and 2 to 5% lower than the semi-empirical values of Chu and Zeigler (1974) in this energy range. The V 2 O 5 stopping power was found to be 2 to 3.5% lower than the Bragg rule curve calculated with the molecular oxygen values of Bourland, Chu, and Powers (1971) and the present vanadium stopping power. The use of Bragg's rule to extract the oxygen contribution to the molecular stopping power of V 2 O 5 results in a solid oxygen stopping power which is in good agreement with the solid molecular oxygen measurement of Chu, Braun, Davies, Matsunami, and Thompson (1978) and approximately 5% higher than Feng's value (1974) obtained from metal oxides which have wide energy band gaps. The present experiment cautions against the use of a common stopping power for oxygen in Bragg rule calculations for solid compounds as purposed by Feng and by Zeigler and Chu (1976)

    Full Text Available Classification of tall-forb vegetation of the Altai using the Braun-Blanquet approach was carried out on the basis of a wide ranging set o[ data from different altitudinal belts. Three main phytosociological types of the tall-forb communities were distinguished within the class MulgedioAconitetea, order Tmllio - Crepidetalia due to performed syntaxonomic analysis. The thermophilous tall-forb communities occurring in the subnemoral belt at altitudes of 259-700 m were included in the alliance Cacalio hastatae - Aconition septentrionalis all. nova. The montain tall-forb meadows of the dark-coniferous taiga belt (altitudes of 800-1700 m were included in the alliance Triseto sibiricae-Aconirlon septentrionalis all. prov. The moderately cryophilous subalpine tall-forb communities widespread at the upper boundary of the forest belt at altitudes of 1000-1900 m were included in the alliance Rhaponticion carthamoidis. Altaian tall-forb vegetation shows a distinct phytosociological and plant geographical unity with European subalpine communities but the closeness of the floristic relations varies in certain altitudinal groups. Most thermophilous tall-forb Siberian meadows of the alliance Cacalio-Aconition which occur at lower altitudes demonstrate strong plant geographical relations with North and Central European meadows of the Adenostyletalia. Gradual decrease of the European floristic relations in the Altaian tall-forb meadows at higher altitudes is shown.

    Full Text Available From 1946 to 1990 an intensive uranium mining had been carried out with underground mining and also with opencast mining by the Wismut enterprise in the southern part of the former GDR. The mining activity lead also in the surroundings of Ronneburg to a permanent growth of devastated areas, among others in the form of dumps and tailings. These areas form by reason of mining-specific contaminations, extrem biotops which demand high claims on the pioneer organisms during the phase of natural first settlement. From 1990 to 1992 vegetation mappings were carried out on 15 dumps of the Thuringia mining area according to Braun-Blanquet (1964. The utilization of the computer programm Flora _D (Frank and Klotz 1990 enabled the ecological characterisation of the dumps. On the 15 investigated dumps found were 498 higher plants, belonging to 65 families. One hundred species are species with a high dominance. The number of species per dump fluctuates between 1 I and 282. Pioneer plants occur on the berms mostly in the second year after stoppage of the dumping, on the slopes after five to ten years. After nearly ten years the first step of settlement seems to be finished. Among the mechanisms of spreading dominate wind- and burdock spread. According to the form of life forms the dump species are predominantly hemicryptophytes, further therophytes, geophytes and phanerophytes.

    We study the stability of asymptotic states displayed by a complex neural network. We focus on the loss of stability of a stationary state of networks using recurrence quantifiers as tools to diagnose local and global stabilities as well as the multistability of a coupled neural network. Numerical simulations of a neural network composed of 1024 neurons in a small-world connection scheme are performed using the model of Braun et al. [Int. J. Bifurcation Chaos 08, 881 (1998), 10.1142/S0218127498000681], which is a modified model from the Hodgkin-Huxley model [J. Phys. 117, 500 (1952)]. To validate the analyses, the results are compared with those produced by Kuramoto's order parameter [Chemical Oscillations, Waves, and Turbulence (Springer-Verlag, Berlin Heidelberg, 1984)]. We show that recurrence tools making use of just integrated signals provided by the networks, such as local field potential (LFP) (LFP signals) or mean field values bring new results on the understanding of neural behavior occurring before the synchronization states. In particular we show the occurrence of different stationary and nonstationarity asymptotic states.

    We develop an analytical model for the thermal boundary conductance between a solid and a liquid. By infusing recent developments in the phonon theory of liquid thermodynamics with diffuse mismatch theory, we derive a closed form model that can predict the effects of wetting on the thermal boundary conductance across an interface between a solid and a classical liquid. We account for the complete wetting (hydrophilicity), or lack thereof (hydrophobicity), of the liquid to the solid by considering varying contributions of transverse mode interactions between the solid and liquid interfacial layers; this transverse coupling relationship is determined with local density of states calculations from molecular dynamics simulations between Lennard-Jones solids and a liquids with different interfacial interaction energies. We present example calculations for the thermal boundary conductance between both hydrophobic and hydrophilic interfaces of Al/water and Au/water, which show excellent agreement with measured values reported by Ge et al. [Z. Ge, D. G. Cahill, and P. V. Braun, Phys. Rev. Lett. 96, 186101 (2006)]. Our model does not require any fitting parameters and is appropriate to model heat flow across any planar interface between a solid and a classical liquid.

    Full Text Available Land-use changes and their effect on overbank sediment accumulation were investigated on the floodplain of Middle-Tisza River. Military survey maps (1783, 1860, 1883 and 1890 and aerial photos (1950, 1965, 1980 and 2000 were used to evaluate land-use changes and to calculate the vegetational roughness of the area. To determinate the rate of overbank sedimentation sediment samples were collected from a pit, the grain-size, content of organic matter, heavy metal content (Pb, Cu, Zn, Ni and Cd and pH were measured. Until 1950 meadows and pastures were typical on the floodplain, gallery-forest was along the river, the oxbow-lake and the artificial levee. Notable landuse changes were detected in the second half of the 20th century, as the aerial photo taken in 1965 shows extensive forestry in the area. These land-use changes affected the average vegetational roughness, as it has been doubled since the disappearance of grasslands. Land-use changes highly affect the aggradation, as the increased roughness decreases the flood velocity on the floodplain, causing accelerated aggradation. Using Pb marker horizons and grain-size changes the studied sediment profile was compared to dated profiles (Braun et al. 2003, thus, the sediment accumulation rate could be determined for the periods of 1858-1965 and 1965-2005. According to our measurements the accumulation rate was doubled since 1965, very likely in connection with the doubled vegetational roughness.

    Aims To use a qualitative approach to further explore the stress and well-being of dental hygiene and dental therapy students (DHDTS) during their undergraduate training.Subjects and methods Semi-structured individual interviews to explore motivation, goals, and perceived stress, were conducted with eight DHDTS from across all three years of study at the University of Portsmouth Dental Academy (UPDA). Thematic analysis of the data was undertaken using Braun and Clarke's (2006) six phases of thematic analysis.Results Three main themes of 'fulfilment', 'the learning environment', and 'perception of stress' were identified. Within these themes, a further 12 sub-themes were identified. Analysis suggested that a strong sense of passion to become a clinician mitigated most, but not all, of the stressful experiences of the DHDTS undergraduate learning environment.Conclusions DHDTS' perceived sources of stress during their undergraduate programme were strongly linked to a sense of meaningfulness.Listen to the author talk about the key findings in this paper in the associated video abstract.

    Rhenium carbonyl hydride chemistry dates back to the 1959 synthesis of HRe(CO)₅ by Hieber and Braun. The binuclear H₂Re₂(CO)₈ was subsequently synthesized as a stable compound with a central Re₂(μ-H)₂ unit analogous to the B₂(μ-H)₂ unit in diborane. The complete series of HRe(CO)(n) (n = 5, 4, 3) and H₂Re₂(CO)(n) (n = 9, 8, 7, 6) derivatives have now been investigated by density functional theory. In contrast to the corresponding manganese derivatives, all of the triplet rhenium structures are found to lie at relatively high energies compared with the corresponding singlet structures consistent with the higher ligand field splitting of rhenium relative to manganese. The lowest energy HRe(CO)₅ structure is the expected octahedral structure. Low-energy structures for HRe(CO)(n) (n = 4, 3) are singlet structures derived from the octahedral HRe(CO)₅ structure by removal of one or two carbonyl groups. For H₂Re₂(CO)₉ a structure HRe₂(CO)₉(μ-H), with one terminal and one bridging hydrogen atom, lies within 3 kcal/mol of the structure Re₂(CO)₉(η²-H₂), similar to that of Re₂(CO)₁₀. For H₂Re₂(CO)(n) (n = 8, 7, 6) the only low-energy structures are doubly bridged singlet Re₂(μ-H)₂(CO)(n) structures. Higher energy dihydrogen complex structures are also found.

    To report the relationship of vegetation structure and environmental gradient and physiochemical properties of soil at Nikyal valley, Azad Jammu and Kashmir . A survey of natural vegetation and soil of Nikyal valley was undertaken. Phytosociological survey was conducted by using Braun-Blanquet's approach. The study also investigated the vegetation structure and its relationship with altitude and edaphic factors. The floristic data was analyzed by cluster anlaysis, detrended correspondence analysis and canonical correspondence analysis using CANACOO 5.0. A total of 110 plant species and 13 stands were merged into five major associations as dema rcated by cluster analysis and detrended correspondence analysis. The associations were Olea-Pinus-Themeda association, Myrsine-Rhus-Quercus association, Quercus-Rubus-Pinus association and Quercus association. Soil organic matter, saturation, pH and altitude play the major role in distribution of species. The variation in vegetation structure is controlled by the altitudinal gradient and physiochemical properties of soil. These results indicate a deteriorated forest structure and reduced regeneration pattern, demanding immediate attention of forest management authorities. Copyright © 2014 Hainan Medical College.

    To examine the caregiving impact of those who support a family member with intellectual disability and epilepsy. An online, qualitative international survey was conducted via the auspices of the International Bureau of Epilepsy with various stakeholders who support individuals who have intellectual disability and epilepsy. Qualitative comments were analyzed from respondents who identified themselves as family members (n=48; 36%) who referred specifically to the impact of supporting a family member with these combined disabilities. Four main domains, which were comprised of ten themes, were derived from the qualitative data using Braun and Clarke's qualitative framework. These domains comprised (1) practical concerns, (2) disrupted family dynamics, (3) emotional burden and (4) positive experiences. In combination these themes illustrate the pervasive impact on family life for those supporting an individual with complex needs. Financial concerns, coordination and responsibility of care, diverted attention from other family members and social isolation all contributed a significant burden of care for family members. Positive aspects were, however, also cited including the closeness of the family unit and a fostering of altruistic behavior. The study provides an insight into an under-researched area. The burden of caring for a family member across the lifespan has a largely negative and pervasive impact. Targeted service provision could contribute to an amelioration of the challenges faced by these families. Copyright © 2014 British Epilepsy Association. Published by Elsevier Ltd.

    On January 20th, 2011, NanoSail-D successfully deployed its sail in space. It was the first solar sail vehicle to orbit the earth and the second sail ever unfurled in space. The 10m2 sail, deployment mechanism and electronics were packed into a 3U CubeSat with a volume of about 3500cc. The NanoSail-D mission had two objectives: eject a nanosatellite from a minisatellite; deploy its sail from a highly compacted volume to validate large structure deployment and potential de-orbit technologies. NanoSail-D was jointly developed by NASA's Marshall Space Flight Center and Ames Research Center. The ManTech/NeXolve Corporation provided key sail design support. NanoSail-D is managed by Marshall and jointly sponsored by the Army Space and Missile Defense Command, the Space Test Program, the Von Braun Center for Science and Innovation and Dynetics Inc. The presentation will provide insights into sailcraft advances and potential missions enabled by this emerging in-space propulsion technology.

    Since the last TRIGA Users Conference in Pavia 1972 the TRIGA reactor Vienna was in operation without any larger undesired shut-down. The integral thermal power production by Sept. 1, 1974 was 3420 MWh. The principal work carried out during the last two years on the reactor system was the installation of a new heat exchanger and primary pump both designed for 1 MW steady state operation. Permission was also obtained from the local authority to withdraw up to 90 m 3 /h secondary cooling water from the well. Some troubles were observed with the pulse rod. After nearly 12 years of operation the connection between the piston rod and control rod broke off just below the water surface. Therefore the piston was shot out without withdrawing the pulse rod itself. After locating the trouble the damage was repaired within one day. The SST fuel elements type 110 were received by the end of 1972 for the purpose of power upgrading. All other fuel elements except one are still located in the reactor core and shifted periodically in order to obtain an optimal burnup. A new alarm system was ordered from Hartmann and Braun and is under installation at the moment. In order to facilitate cooperation with the reactor operation personnel and the experimenters in the reactor hall an accurate power indicator has been installed in the reactor hall which allows all experimenters to read the reactor power as accurately as in the control room itself.
