    Science.gov (United States)

    Minnery, Sarah

    2011-12-01

    General practitioners are regularly called upon to assist their patients in family law disputes. They are often served with a subpoena to produce their patient's file, or that of their children, and can be called upon to provide short reports regarding various health conditions of their patients. Doctors can also sometimes become witnesses in family law litigation and the time needed to participate is rarely compensated. OBJECTIVE This article aims to provide GPs with key information in relation to responding to a subpoena and the preparation of reports in family law matters. Careful preparation of subpoenas and reports by GPs who find themselves embroiled in the family law disputes of their patients can save significant time and costs to all involved.

The term "neutrino" ("little neutral one") was suggested by Enrico Fermi in his 1934 theory of beta-radioactivity which explained how a weak nuclear force could make atomic nuclei unstable. The neutrino, Fermi said, had no mass at all. But the neutrino does interact, slightly, and its importance has grown under the watchful eyes of experimenters and theorists.

    We consider a job contest in which candidates go through interviews (cheap talk) and are subject to reference checks. We show how competitive pressure - increasing the ratio of "good" to "bad" type candi- dates - can lead to a vast increase in lying and in some cases make bad hires more likely. As the number of candidates increases, it becomes harder to in- duce truth-telling. The interview stage becomes redundant if the candidates, a priori, know each others' type or the re...

    Full Text Available The effect of suspended particles on the thermal instability of Walters B' viscoelastic fluid in hydromantic in porous medium is considered. For stationary convection, Walters B' viscoelastic fluid behaves like a Newtonian fluid. The medium permeability and suspended particles has ten the onset of convection whereas the magnetic field postpones the onset of convection, for the case of stationary convection. The magnetic field and viscoelasticity intro duce oscillatory modes in the system which was non-existent in their absence.

    We present a new algorithm for maximum likelihood convolutive ICA (cICA) in which sources are unmixed using stable IIR filters determined implicitly by estimating an FIR filter model of the mixing process. By intro- ducing a FIR model for the sources we show how the order of the filters...... in the convolutive model can be correctly detected using Bayesian model selection. We demonstrate a framework for deconvolving an EEG ICA subspace. Initial results suggest that in some cases convolutive mixing may be a more realistic model for EEG signals than the instantaneous ICA model....

    2011-07-01

    Full Text Available On 17 and 18 March 1938 Barcelona was heavily bombed by the planes of the Legionary Air Force which took off from Palma de Mallorca. Ciano told the English ambassador that the order to bomb had come directly from Franco, but actually it was given by Mussolini to General Valle accidentally met at the Chamber where the Italian duce had gone to deliver a long-awaited speech on the Anschluss. Why was this order given? It has often been asserted that the reasons are to be searched in the will to wear down the civilians, according to the best teachings of Douhet’s air instructions, or in the reaction to the reopening of the French border to allow the aid for the republican faction. These reasons, though well-grounded, have been focused exclusively on the Spanish Civil War. In my article, according to a broader viewpoint considering the approach of the Second World War, I will try to analyze a further reason starting exactly from the annexation of Austria carried out by the Germans and from Mussolini’s explicit desire to increase his reputation in Hitler’s opinion in the hope of a future military alliance. The bombing of Barcelona on 17 and 18 March 1938, from this viewpoint, acquires a communicative dimension of constancy, unscrupulousness and military power that the duce, at least outwardly, catching the euphoric current wave set off by the Anschluss, wanted to transmit to the possible ally.

    Full Text Available Having varied ethnics, cultures, religions, or faiths, Indonesia is considered a multicultural nation in today’s world. This equity can be dangerous; but also can be advantageous if myriad interests of citizens are able to be nurtured through education, including religious schools. The research was conducted to explore multicultural practices in the State-owned Islamic High School (MAN 3 and the Catholic High School (SMA Stella Duce 2 in Yogyakarta Indonesia. Data was gathered via qualitative method by means of comparative study, aiming at seeking similarities and differences on promoting multicultural education values. Findings show similarities of teachers’ attitudes and characteristics as facilitator, accommodator, or assimilator whereas the differences include their leadership role in intrareligious dialog at MAN 3 and dialog leaders at SMA Stella Duce 2. Other issues include diverse understandings of religion and its perceived violence. The research formulates two categories of teacher as being multicultural-intrareligious pluralist and multicultural-intrareligious humanist. It also discusses implications on social change as a result of cultural interchange at those schools.

  18. The strained state cosmology

    CERN Document Server

    Tartaglia, Angelo

    2015-01-01

    Starting from some relevant facts concerning the behaviour of the universe over large scale and time span, the analogy between the geometric approach of General Relativ- ity and the classical description of an elastic strained material continuum is discussed. Extending the elastic deformation approach to four dimensions it is shown that the accelerated expansion of the universe is recovered. The strain field of space-time repro- duces properties similar to the ones ascribed to the dark energy currently called in to explain the accelerated expansion. The strain field in the primordial universe behaves as radiation, but asymptotically it reproduces the cosmological constant. Subjecting the theory to a number of cosmological tests confirms the soundness of the approach and gives an optimal value for the one parameter of the model, i.e. the bulk modulus of the space-time continuum. Finally various aspects of the Strained State Cosmology (SSC) are discussed and contrasted with some non-linear massive gravity theor...

  19. A Semantic Web Blackboard System

    Science.gov (United States)

    McKenzie, Craig; Preece, Alun; Gray, Peter

    In this paper, we propose a Blackboard Architecture as a means for coordinating hybrid reasoning over the Semantic Web. We describe the components of traditional blackboard systems (Knowledge Sources, Blackboard, Controller) and then explain how we have enhanced these by incorporating some of the principles of the Semantic Web to pro- duce our Semantic Web Blackboard. Much of the framework is already in place to facilitate our research: the communication protocol (HTTP); the data representation medium (RDF); a rich expressive description language (OWL); and a method of writing rules (SWRL). We further enhance this by adding our own constraint based formalism (CIF/SWRL) into the mix. We provide an example walk-though of our test-bed system, the AKTive Workgroup Builder and Blackboard(AWB+B), illustrating the interaction and cooperation of the Knowledge Sources and providing some context as to how the solution is achieved. We conclude with the strengths and weaknesses of the architecture.

    2016-01-01

    This paper develops and demonstrates a novel approach for ex-ante assessment of business benefits from IT investments in global supply chains. Extant IT assessment approaches are typically based on the assumption that benefit realization from IT investments involves a single stakeholder and are pro......-duced by the technology as an isolated product. In contrast, research on global supply chains has shown that benefits generated from IT investments in this domain are typically generated by the coor-dinated use of many stakeholders and by technologies producing complimentary effects in systemic relationships....... The assessment approach in this paper brings the contingent inter-organizational and technological dependencies of IT investments to the forefront of the assessment. It provides actors in industries relating to global supply chains the means to better apprehend the possible benefits from an IT investment...

    Full Text Available Two variables are usually used as a basis to make decision of privatization. While this is not necessarily wrong, there in fact other factors that should be taken for consideration but so far being neglected. These are human and cultural factors. This paper discusses these two factors and hypothesizes their implications in the short term and long term. In the short term, it is hypothesized that privatization will create fear, anxiety, stress and dissatisfaction among employees in which their company being privatized but no significance implication to the organizational culture. In the long term it is hypothesized that these fear, anxiety, stress and dissatisfaction will gradually be re¬duced. Despite this expectation, in the long term it is also expected that the success of privatization will be de¬pending on the reaction of the people on the cultural change. Key Words: Privatisasi, perubahan organisasi, perilaku karyawan, budaya organisasi.

  4. Alvarado score: A valuable clinical tool for diagnosis of acute appendicitis –a retros-pective study

    Directory of Open Access Journals (Sweden)

    Swagata Brahmachari1 and Ashwini B. Jajee2

    2013-08-01

    Full Text Available Appendicitis is a common surgical emergency and diagnosis is still a great challenge. Accurate diagnosis and timely intervention re-duces morbidity and mortality. The present study was conducted to evaluate Alvarado scoring system for diagnosis of acute appen-dicitis in Indian set up. The study was carried out on 200 patients admitted in Surgery ward between January 2009 and December 2010 with right lower quadrant abdominal pain. Alvarado score was calculated and all patients were divided in three groups. Mean age of presentation was 29.12 years and male to female ratio was 1.27:1. Higher the Alvarado score, more is the sensitivity. So pa-tients having score 7 or above had sensitivity of 66%. We con-clude that Alvarado score is unique since it incorporates signs, symptoms and laboratory findings of suspicious patients. Alvarado score can be utilized safely for diagnosis of acute appendicitis.

  5. Dynamic capabilities, creative action, and poetics

    Directory of Open Access Journals (Sweden)

    Donald MacLean

    2017-05-01

    Full Text Available Research on dynamic capabilities explores how businesses change enables enterprises to remain competitive. However, theory on dynamic capabilities still struggles to capture novelty, the essence of change. This study argues that a full understanding of strategic change requires us to sharpen our focus on real people and experiences; in turn, we must incorporate other faculties, which almost always operate alongside our logical ones, into our theory. We must pay more attention to the “non­-rational” sides of ourselves—including, but not limited to, our imaginations, intuitions, attractions, biographies, preferences, and aesthetic faculties and capabilities. We argue that all such faculties, on the one hand, are central to our abilities to comprehend and cope with complexity and, on the other hand, foster novel understandings, potential responses, and social creativity. This study intro­duces the possibility of an alternative form of inquiry that highlights the role of poetic faculties in strategic behavior and change.

    2014-10-01

    Full Text Available Landscapes undergoing conservation, valorisation, management and reconstruction policies, become a fundamental factor for the local/global development of natural, cultural, human and social potentials of territories. With the contribution of technological design culture, the research, having a strong multidisciplinary character, focuses on managing the relationship between energy systems and landscapes with the general aim of subverting and transforming apparent conflicts in synergies, in order to overcome a sectorial and segmented approach barely based on energy performances. Through the introduction of a complex multidimensional methodology of analysis and evaluation the goal of this work, is to develop standards of acceptability, meta-design criteria and guidelines for design, intro- ducing a methodology for multidimen- sional complex analysis and evaluation, to support Public Authorities.

  11. Method for rudder roll stabilization control by maintaining ship speed

    Directory of Open Access Journals (Sweden)

    LIU Zhiquan

    2017-01-01

    Full Text Available A ship navigating on the surface of the water may experience greater resistance, adversely affect-ing its speed and leading to energy loss. The added resistance of surface ships in both still water and waves are investigated, and the computation method of total speed loss is presented. An autopilot system is intro-duced to constrain the speed loss, and course keeping and rudder roll stabilization sliding mode control laws are proposed according to a compact control strategy. The two working conditions of "heading" and "heading plus anti-roll" are discussed, including roll stabilization, heading error, speed maintenance and rudder abrasion. The results show that the speed can be effectively maintained using this method, and from a commercial point of view, the fin-rudder roll stabilization control is not recommended for vessels equipped with both fins and rudders.

    The OPERA experiment has for goal the direct detection of !μ ! !! oscilla- tion, using an hybrid apparatus composed of electronic detectors and nuclear photographic emulsions. A charged particle crossing an emulsion layer ion- izes the medium along its path leaving a latent image which leads, after de- velopment, to a sequence of aligned grains. Nuclear emulsions are analyzed by means of optical microscopes to reconstruct the 3D particle tracks. The OPERA collaboration has developed a dedicated system to scan a large num- ber of emulsions (surface of about 1000 m2). The achieved resolution is "1 μm and "1 mrad allowing to observe directly the short-lived " particles pro- duced in !!CC interactions.

    Verstraete, Brecht; Janssens, Steven; Rønsted, Nina

    2017-01-01

    -pathological endo- phytes are present in the leaves of their hosts. It is hypothesized that the bacterial endophytes, either alone or by interacting with the host, provide chemical protection against herbivory or pathogens by pro- ducing toxic or otherwise advantageous secondary metabolites. If the bacteria indeed...... have a direct ben- eficial influence on their hosts, it is reasonable to assume that the endophytes may increase the fitness of their hosts and therefore it is probable that their presence also has an influence on the long-term evolu- tion of the particular plant lineages. In this study, the possible...... origin in time of non-nodulated bacterial leaf symbiosis in the Vanguerieae tribe of Rubiaceae is elucidated and dissimilarities in evolutionary dynamics between species with endophytes versus species without are investigated.

    The CERN SPS will be used as a test-bed for the LHCprototype crab-cavities, which will be installed and testedin the SPS in 2018. As the time available for experimen-tal beam dynamics studies with the crab cavities installedin the machine will be limited, a very good preparation isrequired in advance. One of the main concerns is the in-duced emittance growth, driven by phase jitter in the crabcavities. In this respect, several machine development (MD)studies were performed during the past years to quantifyand characterize the emittance evolution of proton beamsin coast in the SPS. In these proceedings, the experimentalobservations from past years are summarized and the MDstudies from 2016 are presented. Finally, a proposal for anexperimental program for 2017 is discussed.

    Schaefer, D M; The ATLAS collaboration

    2012-01-01

    Since starting in 2010, the Large Hadron Collider (LHC) has pro- duced collisions at an ever increasing rate. The ATLAS experiment successfully records the collision data with high eciency and excel- lent data quality. Events are selected using a three-level trigger system, where each level makes a more re ned selection. The level-1 trigger (L1) consists of a custom-designed hardware trigger which seeds two higher software based trigger levels. Over 300 triggers compose a trig- ger menu which selects physics signatures such as electrons, muons, particle jets, etc. Each trigger consumes computing resources of the ATLAS trigger system and oine storage. The LHC instantaneous luminosity conditions, desired physics goals of the collaboration, and the limits of the trigger infrastructure determine the composition of the ATLAS trigger menu. We describe a trigger monitoring frame- work for computing the costs of individual trigger algorithms such as data request rates and CPU consumption. This framework has been used...

  3. A dual-chamber method for quantifying the effects of atmospheric perturbations on secondary organic aerosol formation from biomass burning emissions

    Biomass burning (BB) is a major source of atmospheric pollutants. Field and laboratory studies indicate that secondary organic aerosol (SOA) formation from BB emissions is highly variable. We investigated sources of this variability using a novel dual-smog-chamber method that directly compares the SOA formation from the same BB emissions under two different atmospheric conditions. During each experiment, we filled two identical Teflon smog chambers simultaneously with BB emissions from the same fire. We then perturbed the smoke with UV lights, UV lights plus nitrous acid (HONO), or dark ozone in one or both chambers. These perturbations caused SOA formation in nearly every experiment with an average organic aerosol (OA) mass enhancement ratio of 1.78 ± 0.91 (mean ± 1σ). However, the effects of the perturbations were highly variable ranging with OA mass enhancement ratios ranging from 0.7 (30% loss of OA mass) to 4.4 across the set of perturbation experiments. There was no apparent relationship between OA enhancement and perturbation type, fuel type, and modified combustion efficiency. To better isolate the effects of different perturbations, we report dual-chamber enhancement (DUCE), which is the quantity of the effects of a perturbation relative to a reference condition. DUCE values were also highly variable, even for the same perturbation and fuel type. Gas measurements indicate substantial burn-to-burn variability in the magnitude and composition of SOA precursor emissions, even in repeated burns of the same fuel under nominally identical conditions. Therefore, the effects of different atmospheric perturbations on SOA formation from BB emissions appear to be less important than burn-to-burn variability.

    The federal Certificate of Confidentiality plays an important role in research on sensitive topics by authorizing researchers to refuse to disclose identifiable research data in response to subpoenas in any legal setting. However, there is little known about how effective Certificates are in practice. This article draws on our legal and empirical research on this topic to fill this information gap. It includes a description of the purpose of Certificates, their legislative and regulatory history, and a summary of the few reported and unreported cases that have dealt with Certificates. In addition, we outline other statutory confidentiality protections, compare them to the Certificate's protections, and analyze some of the vulnerabilities of a Certificate's protections. This analysis allows us to make specific recommendations for strengthening the protections afforded to research data. © 2015 American Society of Law, Medicine & Ethics, Inc.

  7. Effects of all Trans Retinoic Acid Combined with Cisplatin on Survival of Gastric Cancer Cell Line (AGS

    Directory of Open Access Journals (Sweden)

    2013-10-01

    Full Text Available Introduction & Objective: All-trans retinoic acid, a derivative of retinoids, is widely used to in-duce prolifferation, differentiation and apoptosis in normal, precancareous and cancerous cells. Cisplatin, an effective drug for cancer treatment, induces apoptosis via cross-linking to DNA. Previous studies on ovarian and melanoma cancer cells have showed synergistic ef-fects of cisplatin and retinoic acid. Our aim is to study such synergistic effect on gastric de-rived cell line, AGS. Materials & Methods: In this experimental study gastric cancer cell line was cultured with dif-ferent concentration of retinoic acid and cisplatin and their combination. The cell death was evaluated with clonogenic assay and Acridine Orange/ Ethidium Bromide staining. Results: The results showed that all-trans retinoic acid had not significant effect on cell death in gastric cancer. The results showed that high doses of retinoic acid and cisplatin can cause cell death via necrosis and early apoptosis, respectively. The plates were treated with the combination of 10 µM retinoic acid and 5, 10 µg cisplatin, and more cell death were ob-served (P<0.001. It seems that, suseptability of this cell line to retinoic acid is dose depend-ent. Conclusion: In this study, we concluded that the combination of retinoic acid and cisplatin was more effective on cell death than cisplatin and retinoic acid alone.

    Studies show that McGRATH® MAC (McG) is useful during direct laryngoscopy. However, no study has examined whether McG re- duces pressure on the upper airway tract We compared direct vision with indirect vision concerning pressure on the larynx and tongue. Twenty two anesthesiologists and 16 junior residents attempted direct laryngoscopy of airway management simulator using McG with direct vision and indirect vision. Pressure was measured using pressure measurement film. In anesthesiologists group, pressure on larynx was 14.8 ± 2.7 kgf · cm(-2) with direct vision and 12.7 ± 2.7 kgf · cm(-2) with indirect vision (P vision and 7.6 ± 2.8 kgf · cm(-2) with indirect vision (P = 0.18). In junior residents group, pressure on larynx was 19.0 ± 1.3 kgf · cm(-2) with direct vision and 14.1 ± 3.1 kgf · cm(-2) with indirect vision (P vision and 11.2 ± 4.7 kgf · cm(-2) with indirect vision (P vision can reduce pressure on the upper airway tract.

    Full Text Available Vertical infraclavicular brachial plexus block is utilized in patients with chronic renal failure at the time of creation of an arterio-venous fistula (AVF. The aim of this study is to test the effect of impaired renal function, with the resulting deranged serum electrolytes and blood gases, on the success rate and the onset of action of the local anesthetics used. In this prospective clinical study, we investigated the effect of the serum levels of sodium, potassium, urea, crea-tinine, pH, and bicarbonate on the onset of action of a mixture of lidocaine and bupivacaine administered to create infraclavicular brachial plexus block. A total of 31 patients were studied. The success rate of the block was 93.5 % (29 patients. The mean onset time for impaired or re-duced sensation was found to be 8.9 ± 4.7 mins and for complete loss of sensation, was 21.2 ± 6.7 mins. There was no significant association with serum sodium, potassium, urea, creatinine or the blood pH level (P> 0.05. The bivariate correlation between serum bicarbonate level and the partial and complete sensory loss was -0.714 and -0.433 respectively, with significant correlation (P= 0.00, 0.019. Our study suggests that infraclavicular block in patients with chronic renal failure carries a high success rate; the onset of the block is delayed in patients with low serum bicarbonate levels.

    Full Text Available An urgent issue for power plants operating on solid fuels (coal is the issue of utilization or use of accumulated production waste - ash and slag materials - in the related production. Ash-slag materials are classified as “waste”, usually grade 5; tens of millions of tons of them being pro-duced annually in the Kemerovo region, which threatens the ecology of the region. At the same time, ash and slag is a very promising raw material. The use of this material as a base for the final product allows us to signifi-cantly expand the possibilities of using coal. The most widespread is the system of ash and slag involving in construction or as a replacement for sand in road construction, or as an additive to building mixtures. However, there are both industrially valuable and environmentally dangerous ele-ments in ash-slag materials. Ash-slag materials can be considered as inde-pendent ore deposits located on the surface and requiring the costs of their extraction.

    Full Text Available The aim of my paper is to scrutinize the manifold interpretations of proper names and their possible symbolical value that the reading of F. S. Fitzgerald's classic leaves in the reader. On the whole, the novel's internal structure is rather comprised, which consequently makes the story exact, its plot condensed, but behind this seemingly concise and more or less simple language the author nevertheless manages to embody powerful symbolism that speaks for itself. It is disputable whether Fitzgerald truly aimed to produce such a strong metaphorical emphasis that would most minutely delineate America's social character in the turbulent twenties as projected in the personal stories of the novel's leading protagonists. Within this figurative scope, large as it is, 1 therefore focus only on the significance of proper names and their obvious contribution to the holistic social portrayal. It may be only a minor, but nevertheless one of the most reliable and crucial means of outlining the consequences of the postwar spiritual apathy that overwhelmed the American nation and was in­ duced by the societal downfall due to the disillusion of the American Dream. How this Dream influenced each individual's and society's destiny remains to be my goal in this article. For the purpose of analysis 1 rely on the 1994 Penguin edition.

    Templ, Sebastian; Sauerzopf, Clemens

    In the Standard Model of particle physics, CPT symmetry is regarded as invariant. In order to test this prediction, the ASACUSA collaboration (“Atomic Spectroscopy And Collisions Using Slow Antiprotons”) aims to make a very precise measurement of the hyperfine structure of antihydrogen with a Rabi-like experiment. The compar- ison of the experimentally-obtained antihydrogen transition frequencies with those of hydrogen allows for a direct test of CPT symmetry. The spectrometer line of the ASACUSA HBAR-GSHFS (“Antihydrogen ground state hyperfine splitting”) experiment consists of a particle source, a spin flip-in- ducing microwave cavity, a spin-analyzing sextupole magnet, and a detector. In the course of the work for this thesis, a single scintillation detector as used in the hodoscopes of the detector at the end of the spectrometer line was simulated using the particle physics toolkit Geant4. Subsequent analysis of the simulation data allows for an estimate of the minimal uncertainty in determining t...

    Full Text Available The study assessed sensorial aspects and physicochemical characteristics of two non- commercial genotypes of cherry tomato, CH152 and CLN1561, and compared them to the genotype Carolina, all grown organically. Ripened fruits of the three varieties were harvested at the same time, selected, cleaned and subjected to sensorial analysis by 50 adult testers. They used a 9-point hedonic scale to classify the fruits in terms of aroma, flavor, flesh color and general appearance. The physicochemical analyses determined pH, solu- ble solids (SS and titratable acidity (AT. For the aspects aroma and general appearance, the 3 varieties ob- tained mean scores of 7.0 to 7.9, which corresponds to “like moderately”; and scored 8.0 to 8.9 to the attribute flesh color, which represents “like very much”. For the attribute flavor, the scores of “Carolina” tomatoes and CLN1561A corresponded to “like moderately, and for CH152 it was “like very much”. The mean values of physicochemical parameters (pH = 4.41 to 4.61; SS = 4.03 to 5.06; and AT = 335.13 to 369.23 were similar among the genotypes (ANOVA, P>0.05. In conclusion, both the varieties tested, CH152 and CLN1561, pro- duce fruits of high sensorial and physicochemical quality, showing potential for commercial exploitation.

    2016-04-01

    Full Text Available Organic Struggle chronicles the challenges encountered by innovators in a growing segment of the U.S. food pro- duction and marketing system. Practiced for millenia by farmers before the introduction of chemical fertilizers and pesticides, and first developed more formally in Europe, organic farming practices began to gain prominence in the U.S. only in the 1950s. Far more than a system for pro- ducing food, this strategy has become a focus for those supporting healthy and pesticide-free products, for some who embrace the organic system as a food movement, and by many who disagree with the current domination of the country’s food industry by large farms and a small num- ber of multinational corporations. Within the organic sector there is debate between those who favor a system primar- ily run by local farmers who sell through small markets and CSAs, and others who insist that the ‘Big-Organic’ seg- ment that now sells more than half of all organic food is doing more to help the environment in the large picture. Author Brian Obach describes this ongoing struggle.

    In the Saccharomyces cerevisiae yeasts, the DOT1 gene product provides methylation of lysine 79 (K79) of hi- stone H3 and the SET2 gene product provides the methylation of lysine 36 (K36) of the same histone. We determined that the dot1 and set2 mutants suppress the UV-induced mutagenesis to an equally high degree. The dot1 mutation demonstrated statistically higher sensitivity to the low doses of MMC than the wild type strain. The analysis of the interaction between the dot1 and rad52 mutations revealed a considerable level of spontaneous cell death in the double dot1 rad52 mutant. We observed strong suppression of the gamma-in- duced mutagenesis in the set2 mutant. We determined that the dot1 and set2 mutations decrease the sponta- neous mutagenesis rate in both single and d ouble mutants. The epistatic interaction between the dot1 and set2 mutations and almost similar sensitivity of the corresponding mutants to the different types of DNA damage allow one to conclude that both genes are involved in the control of the same DNA repair pathways, the ho- mologous-recombination-based and the postreplicative DNA repair.

  18. Heat transfer augmentation of magnetohydrodynamics natural convection in L-shaped cavities utilizing nanofluids

    Directory of Open Access Journals (Sweden)

    Sourtiji Ehsan

    2012-01-01

    Full Text Available A numerical study of natural convection heat transfer through an alumina-water nanofluid inside L-shaped cavities in the presence of an external magnetic field is performed. The study has been carried out for a wide range of important parame­ters such as Rayleigh number, Hartmann number, aspect ratio of the cavity and solid volume fraction of the nanofluid. The influence of the nanoparticle, buoyancy force and the magnetic field on the flow and temperature fields have been plotted and discussed. The results show that after a critical Rayleigh number depending on the aspect ratio, the heat transfer in the cavity rises abruptly due to some significant changes in flow field. It is also found that the heat transfer enhances in the presence of the nanoparticles and increases with solid volume fraction of the nanofluid. In addition, the performance of the nanofluid utilization is more effective at high Ray­leigh numbers. The influence of the magnetic field has been also studied and de­duced that it has a remarkable effect on the heat transfer and flow field in the cavity that as the Hartmann number increases the overall Nusselt number is significantly decreased specially at high Rayleigh numbers.

    The Total Antioxidant Capacity (TAC) of human milk reflects the concentration and the activity of many components which prevent oxidative degradation of fats and proteins. This study compares the effectiveness of ABTS and DPPH tests with regard to the recovery, precision and sensitivity (detection and quantification limit) of (TAC) values in human milk. TAC values were determined in twenty five samples of human milk obtained from healthy mothers, residents of Gdańsk, on the 14th day postpartum. The average TAC of human milk determined by ABTS assay was 19.61 ±3.311 mg TE (Trolox Equivalents)/100 cm3, the average values obtained by the DPPH assay reached 9.95 ±4.36 mg TE/100 cm3. For each milk sample the TAC determined by the ABTS test was significantly higher than the values pro- duced by the DPPH test. The above findings can be attributed to the presence of substances whose spectra overlap with DPPH• spectra. ABTS test was characterised by a higher sensitivity and repeatability of the determination of TAC in human milk compared to the DPPH test. Comparing the calculated values for the validation parameters of both methods and taking into account the solubility of DPPH only in polar matrices, slower reaction of selected antioxidants with DPPH radical, and the presence in human milk constituents absorbing electromagnetic radiation in the absorption of DPPH be assumed that the ABTS test is more appropriate method of determining of TAC in breast milk.

    1993-01-01

    While the first two volumes on Scanning Tunneling Microscopy (STM) and its related scanning probe (SXM) methods have mainly concentrated on intro­ ducing the experimental techniques, as well as their various applications in different research fields, this third volume is exclusively devoted to the theory of STM and related SXM methods. As the experimental techniques including the reproducibility of the experimental results have advanced, more and more theorists have become attracted to focus on issues related to STM and SXM. The increasing effort in the development of theoretical concepts for STM/SXM has led to considerable improvements in understanding the contrast mechanism as well as the experimental conditions necessary to obtain reliable data. Therefore, this third volume on STM/SXM is not written by theorists for theorists, but rather for every scientist who is not satisfied by just obtaining real­ space images of surface structures by STM/SXM. After a brief introduction (Chap. 1), N. D. Lang first co...

    Full Text Available Fish in captivity can show some dysfunctions, at different levels, in the physiological processes of reproduction, due to  the lack of synthesis or release of gonadotropins (GtHs by hypophysis. As a consequence, a worsening of quality and  quantity of spawned gametes, or a lack of egg and sperm spawning, can be observed. The farmers can act on fish repro-  ductive cycle manipulating the environmental parameters of rearing, the diet, the genetics or using GnRH treatments.  Nowadays, they are used mainly GnRH, synthesized in laboratory as analogues. These releasing factors, naturally pro-  duced by hypothalamus, let to overcome the technological and biological limits of the “traditional” hormonal treatments  with hCG, being more effective, cheaper and easily available on market. This article makes a historical survey of the con-  ditioning treatments for fish reproduction and also considers the future perspectives of these treatments, examining the  topics that research will have to focus, in order to make these treatments common worldwide, in any hatchery and for  each farmed  species of finfish.

    Hadronic resonances serve as a unique tool to study the properties of hot and dense matter pro- duced in heavy-ion collisions. These properties can be studied by measuring the ratios of hadronic resonance yields to the yields of longer-lived hadrons which can be used to investigate the re- scattering effects and the chemical freeze-out temperature. Resonance measurements in pp and p–Pb collisions provide a necessary baseline for heavy-ion data and help to disentangle the initial- state effects from medium-induced effects. The ALICE Collaboration has measured resonances such as, K ∗ (892) 0 and φ (1020) in pp, p–Pb, and Pb–Pb collisions at the LHC energies. These resonances are reconstructed via their hadronic decay channel in a wide momentum range at midrapidity. In this work, we present recent results on the transverse momentum spectra, mean transverse momentum, ratios of resonance production relative to that of long-lived hadrons.

    An urgent issue for power plants operating on solid fuels (coal) is the issue of utilization or use of accumulated production waste - ash and slag materials - in the related production. Ash-slag materials are classified as "waste", usually grade 5; tens of millions of tons of them being pro-duced annually in the Kemerovo region, which threatens the ecology of the region. At the same time, ash and slag is a very promising raw material. The use of this material as a base for the final product allows us to signifi-cantly expand the possibilities of using coal. The most widespread is the system of ash and slag involving in construction or as a replacement for sand in road construction, or as an additive to building mixtures. However, there are both industrially valuable and environmentally dangerous ele-ments in ash-slag materials. Ash-slag materials can be considered as inde-pendent ore deposits located on the surface and requiring the costs of their extraction.

    Full Text Available Failure in timber structures occurs mainly in crucial points such as joints areas. Therefore, the idea of using composite sheets in timber joints has been intro-duced as a method in order to increase the strength and ductility behaviour of timber joints. This research aims to study the behaviour of bolted joints in poplar and pine woods, which are reinforced by two types of GFRP sheets. A single shear bolted joint consisted of 3 timber members whose length and width were 30 cm in length and 5 cm in width. The thickness of each member was 4 cm for internal part and 2 cm for external part. The employed steel bolt was 10 cm in length and 1 cm in diameter. In this respect, one layer of GFRP sheet was used to be bonded to timber members by using epoxy resin and left between the clamps for 24 hours. They were then kept at room temperature for three weeks. Also the effect of adding a wood veneer on the reinforced joints was investigated. The tensile strength of the reinforced and control samples (un-reinforced joints was measured according to ASTM D5652-92 standard. The results show that the reinforced samples have higher tensile strength compared to that of reinforced joints, although it is not statistically signifcant. Also, two types of sheets infuence the joint behaviour as the reinforced joints display more ductility behaviour.

    Full Text Available The article considers the choice of the lubricants for using in the bolted joints of the serial gas-turbine engine AL-31. In a modern gas turbine engine complex bolted joints operating in various conditions are used. They are subject to demolition in the repair process, in which they break as the result of burning and thus the increase of the breakaway mo- ment. On the basis of maintenance conditions analysis there were determined the most characteristic defects in bolted joints, as well as the reasons for their occurrence. It was established that the main cause of failure of bolted joints is the increase breakaway moment of bolted joint. To reduce the breakaway moment one should choose such lubricants as to re- duce the thermal influence on the bolt and prevent it from being destroyed in the disassembly process. For choosing lubri- cations the analysis of the requirements for lubricants for bolted joints used at high temperatures was conducted. Lubricants choice was made based on the results of a comparative study of various compositions of lubricant application in the process of field testing. This research work is aimed to improve the efficiency of bolted connections in a wide operating range and to prevent the increase breakaway moments in gas-turbine engine repair. Obtained in the process of field testing results allow to suggest a lubricant that can be used in the bolt connection operating at high temperatures and to reduce the break- away moment compared to the commercially used one.

    Full Text Available JOHN LOCKE AND THE POWER OF THE FAMILY OVER EDUCATION. Who deserves author-ity over education? Plato was convinced that it was the state. Locke insisted onthe family. Mill, from his own hard-won experience, was convinced that theindividual should have more influence than the family. Of course, childrenhad to be compelled to learn basics; otherwise their freedom would be re-duced. John Locke lived in a time of growing capital formation. He defendedthe right of ownership as a fundamental human right. According to him, itfollowed from the right to life. Property was created through work, and workwas a way of using life. Parents had to have the decisive influence on educa-tion. They needed to be convinced that their heirs would manage their inher-itance in a responsible way. Locke is regarded as a father of democracy. How-ever, it can hardly be claimed that he was a promoter of democracy in educa-tion. His defence of private property led him to ascribe so much power overeducation to parents that individual rights were substantially curtailed.

    1994-06-01

    The objective of the modeling and simulation task was to develop, test, and apply an appropriate set of models that could translate emission changes into air quality changes. Specifically, we wanted to develop models that could describe how existing measurements of ozone (O{sub 3}), carbon monoxide (CO), and sulfur dioxide (SO{sub 2}) would be expected to change if their emissions were changed. The modeling must be able to address the effects of difference in weather conditions and changes in land use as well as the effects of changes in emission levels. It must also be able to address the effects of changes in the nature and distribution of the emissions as well as changes in the total emissions. A second objective was to provide an understanding of the conditions that lead to poor air quality in Mexico City. We know in a general sense that Mexico City`s poor air quality is the result of large quantities of emissions in a confined area that is subject to light winds, but we did not know much about many aspects of the problem. For example, is the air quality on a given day primarily the result of emissions on that day...or is there an important carryover from previous nights and days? With a good understanding of the important meteorological circumstances that lead to poor air quality, we learn what it take duce an accurate forecast of impending quality so that we can determine the advisability of emergency measures.

    Full Text Available As a social practice, language is used to persuade, influence, argue, refuse, maintain, and to response one’s reaction. Using language, one may practically pro- duce and reproduce authority. This article deals with the symbolic fight and the mechanism of symbolic force within politics discourse in written media. The analy- sis technique used is critical discourse analysis, especially in the interaction be- tween language and social structure. The result shows that the symbolic fight in the written media represents the practice of continuing the doxa by the orthodoxa group and of attacking it by the heterodoxa group. The strategies of fighting the doxa are by showing the orthodoxa group’s weaknesses, arousing the enmity within the group, comparing the orthodoxa group to others, and by using SARA and com- munity issues. The mechanism of the symbolic force used by the ortodoxa is the use of euphemism and censor.   Key words: kekuasaan simbolik, doxa, orthodoxa, SARA, dan wacana politik.

    Full Text Available Having dedicated more than 20 years to this single major lexicographic project, the authors, Professor Wilfrid H.G. Haacke and Pastor Eliphas Eiseb, have pro-duced a dictionary of amazing quantity and quality. The newly published Khoekhoegowab Dictionary comprises some 25 000 Khoekhoegowab entries and the English renderings in the English-Khoekhoegowab index amount to over 26 000 entries. While these figures are quite impressive in themselves, the reader will also find a thorough analysis of the Khoekhoegowab entries as well as refined English translations. The dictionary attempts to address the interests of linguists as well as the needs of the speech community. Unavoidably, the divergent interests of these two groups force the authors to accept a number of compromises that result in some inconvenience for both the target audiences. Despite these limitations, linguistic research on African languages will find the dictionary a source of eminent importance for both historical linguistics as well as typological studies. And mother-tongue speakers will greatly benefit from this publication, which, thanks to financial support from the German technical assistance agency GTZ, is available at a price that is affordable for the Namibian public.

    2014-01-01

    The ATLAS experiment is designed to study the proton-proton collisions pro- duced at the Large Hadron Collider(LHC) at CERN. Liquid argon sampling calorimeters are used for all electromagnetic calorimetry covering the pseudo- rapidity region up to 3.2, as well as for hadronic calorimetry in the range 1.5-4.9. The electromagnetic calorimeters use lead as passive material and are characterised by an accordion geometry that allows a fast and uniform az- imuthal response without any gap. Copper and tungsten were chosen as pas- sive material for the hadronic calorimetry; whereas a classic plate geometry was adopted at large polar angles, an innovative one based on cylindrical elec- trodes with thin argon gaps was designed for the coverage at low angles, where the particles flow is higher. All detectors are housed in three cryostats kept at approximately 89 K. After installation in 2004-2006, the calorimeters were extensively commissioned over the three-year period prior to first collisions in 2009, using cosmic ra...

    Full Text Available In the Spanish Civil War 5699 soldiers and more than 700 planes of the Italian Regia Aeronautica (Italian Royal Air Force intervened. This military unit, in order not to put out Italian flags or badges, having regard to the secrecy of the military intervention in a foreign country, was named Legionary Air Force. In my article I will try to highlight the Italian anomalies of the political-strategic highest authorities who led to the decision of intervening in the Spanish conflict, since leaders that had no competent authority took part in the decision of the military intervention, while those who had full powers did not take part in it. Moreover, I will try to underline the heavy oddities related to the employment and the command of the aircraft which was often used according to the old legacy of the land force in order to substitute the artillery or the tanks. Finally, considering the Spanish conflict as a prelude to the Second World War, I will point up how the commitment in Spain led to false instructions in the military domain, maintained in the most challenging world conflict, as well as how the want of war material complained by the Italian duce in 1943 is to ascribe to the Italian limited far-sightedness in its commitment alongside Generalissimo Francisco Franco.

    During the last decade and a half, studies of evolution and variation have been revolutionized by the introduction of the methods and concepts of molecular genetics. We can now construct reliable phylogenetic trees, even when fossil records are missing, by compara­ tive studies of protein or mRNA sequences. If, in addition, paleon­ tological information is available, we can estimate the rate at which genes are substituted in the species in the course of evolution. Through the application of electrophoretic methods, it has become possible to study intraspecific variation in molecular terms. We now know that an immense genetic variability exists in a sexually repro­ ducing species, and our human species is no exception. The mathematical theory of population genetics (particularly its stochastic aspects) in conjunction with these new developments led us to formulate the "neutral theory" of molecular evolution, pointing out that chance, in the form of random gene frequency drift, is playing a much more importa...

  17. Improvement of PLL algorithm for the LEP Q-meter

    CERN Document Server

    Berrig, O E

    1998-01-01

    The PLL (Phase Locked Loop) has two modes: search mode and locking mode. The mode is determined by how far apart the internal frequency is from the external frequency. When the internal - and exter nal frequencies are close, the PLL is in locking mode. While locking on the external frequency, the PLL can largely be expressed as a linear term superimposed with a small "noise" term. We can t herefore calculate a transfer function that will completely describe the performance of the PLL apart from the precision, which is determined by the noise term. Two ideas are presented on how to re duce the noise term. The first idea is to compensate the noise term with an equal value of opposite sign. This completely removes the noise when the PLL locks on a steady frequency. Unfortunately it can not be used for the LEP Q-meter which is plagued by the presence of satellite frequencies. For other equipment with cleaner spectra, the method can improve their precision dramatically. T he second idea reduces the noise level wit...

    Full Text Available Background: The Long-lasing insecticide impregnated nets (LLINs is considered as an effective tools for malaria vector control. The aim of this study was to evaluate the residual efficacy of alpha-cypermethrin long lasting im­pregnated nets (LLIN-Interceptor® against Anopheles stephensi using tunnel test.Methods: The wash-resistance of Interceptor® nets were assessed under laboratory conditions using tunnel test. Females of An. stephensi were released into the tunnel and then they were provided blood meals from guinea pigs. Bed nets were washed according to the standard procedure up to 20 times. The bioefficacy indicators such as inhi­bition of bloodmeal from experimental animal, knockdown, irritancy rate, survival rate, entry index and mortality were calculated.Results: It induced 90–100% mortalities in the population of An. stephensi up to 15 washes. The KT50 values re­duced from 73.47 to 26.30 minutes in unwashed in comparison to one washed, respectively. The mean of mortality rate of blood-feeding inhibition and entry indexes was reached to 91.6%±2.8, 87.0±3.4 and 24.9±2.8 respectively after 20 washing.Conclusion: This net could provide a good personal protection against malaria vectors and could induce relatively high mortality, inhibit the blood-feeding as well as reduce the entry rates of female mosquitoes even after several washes.

    Full Text Available Contrast media induced nephropathy (CIN results in significant morbidity and mortality. We therefore investigated whether theophylline (adenosine antagonist reduces the inci-dence of contrast media induced nephropathy. Two hundred and eighty patients were randomly assigned to prophylactic administration of hydration with sodium bicarbonate plus theophylline (either orally or intravenously (n=128 or hydration with sodium bicarbonate only (n=152. Blood Urea, creatinine, and glomerular filtration rate (MDRD were measured before and after administration of contrast media. Both groups were similar in clinical characteristics and amount of contrast used. Theophylline prophylaxis significantly reduced the incidence of CIN (1.6% vs 7.9%; P= 0.015. Compared to low-risk patients, Theophylline prophylaxis significantly reduced the incidence of CIN in moderate and high-risk patients (0% vs 8.8%; P= 0.022 and 9.1% vs 42.1%; P= 0.014 respectively. In conclusion, prophylactic administration of theophylline re-duces the incidence of CIN in moderate and high-risk patients for CIN.

    2012-12-01

    Full Text Available A novel method to provide high-resolution Two-Dimensional Direction of Arrival (2D DOA estimation employing Artificial Neural Networks (ANNs is presented in this paper. The observed space is divided into azimuth and elevation sectors. Multilayer Perceptron (MLP neural networks are employed to detect the presence of a source in a sector while Radial Basis Function (RBF neural networks are utilized for DOA estimation. It is shown that a number of appropriately trained neural networks can be successfully used for the high-resolution DOA estimation of narrowband sources in both azimuth and elevation. The training time of each smaller network is significantly re¬duced as different training sets are used for networks in detection and estimation stage. By avoiding the spectral search, the proposed method is suitable for real-time ap¬plications as it provides DOA estimates in a matter of seconds. At the same time, it demonstrates the accuracy comparable to that of the super-resolution 2D MUSIC algorithm.

    2017-01-01

    Full Text Available Increasing demands for the reduction of exhaust emissions and the pursuit to re-duce the use of fossil fuels require the search for new fuelling technologies in combustion engines. One of the most promising technologies is the multi-fuel compression ignition engine concept, in which a small dose of liquid fuel injected directly into the cylinder acts as the ignition inhibitor of the gaseous fuel. Achieving the optimum combustion process in such an engine requires the application of advanced control algorithms which require mathematical modelling support. In response to the growing demand for new simulation tools, a 0-D model of a dual-fuel engine was proposed and validated. The validation was performed in a broad range of engine operating points, including various speeds and load condition, as well as different natural gas/diesel blend ratios. It was demonstrated that the average model calculation error within the entire cycle did not exceed 6.2%, and was comparable to the measurement results cycle to cycle variations. The maximum model calculation error in a single point of a cycle was 15% for one of the complex (multipoint injection cases. In other cases, it did not exceed 11%.

    2016-05-01

    One of the central matters in forensic psychiatry is its culpability. Day after day we, the mental health professionals, are subpoenaed in different courts of our country to assess the mental state of a given individual in order to endorse a judge so that he can issue their view pertaining the culpability and the responsibility of accused subjects. Our current National Criminal Code, dating from 1921, in Art. 34 sub 1 holds for culpability a dichotomous model in which an individual is responsible and must be accountable for his behavior or not responsible and in such case must no be held accountable in criminal courts. This dichotomous model often does not permit the correct analysis of the psychopathology making sometimes the psychiatrist to force a conclusion according to this paradigm imposed by Justice. As we all know reality does not reflect itself under discrete categories and notwithstanding this is the written norm, people, thoughts, emotions and behaviors manifest in dimensions where boundaries are not always clear. Hence, we are considering it necessary to give effect to the impulses for the reform of the existing Criminal Code to lead to diminish culpability.

    Little data describes the role of child abuse pediatricians in consultation for physical abuse patients the pediatric emergency department. To compare adherence in the emergency department to hospital physical abuse guidelines and need to return for testing between 2 groups: those receiving a child abuse consultation in the pediatric emergency department vs those who received standard emergency department care with subsequent child abuse review. We reviewed 471 records of visits to the pediatric emergency department for physical abuse. Data collected included demographics, studies performed, whether patients need to return after child abuse review, child abuse subpoenas, child abuse testimony in court. Patients who received a child abuse consult in the emergency department or inpatient were more likely to be younger and to have more severe injuries. In cases where a consult was obtained, there was 100% adherence to emergency department clinical guidelines vs 66% when no consult was obtained. In addition, in cases that did not receive a child abuse consult, 8% had to return to the hospital for labs or radiographs after their emergency department visit. Child abuse consultation in the pediatric emergency department improves compliance with clinical guidelines and decreases the likelihood that patients will need to return for further testing.

    Increased awareness by crime scene detectives has led to a rise in number of bite mark associated cases appearing before the South African courts. This has led to an increased number of dentists being subpoenaed to give forensic evidence. The purpose of this paper was to elucidate the presentation of evidence in pattern associated tooth mark analysis. Three aspects are discussed. They are the basic principle of pattern association, the effects of limited shrinkage and distortion on the pattern of the tooth marks, and finally how to overcome the difficulties that court personnel experience in visualising bite marks. The author has applied these basic concepts over the past six years. Judges and defence advocates have been able to understand the simple concepts and apply them to the more complex issues before them. The concepts described should be familiar to all dentists and forensic odontologists giving tooth mark evidence in the high court. They will assist in explaining all aspects of pattern association to the legal fraternity and aid in the presentation of the evidence. Their strength is in their simplicity.

    Portfolios have emerged in graduate medical education despite lack of consensus on their definition, purpose, or usefulness. Portfolios can be used as a tool for residents to record their accomplishments, reflect on their experiences, and gain formative feedback. This exercise may help prepare physicians for lifelong learning as well as enhance patient care. The Accreditation Council for Graduate Medical Education has endorsed and may soon require the use of portfolios as an assessment tool to evaluate resident competence. However, using portfolios for summative evaluation purposes such as making high-stakes decisions on resident promotion or matriculation may deter resident candidness. In addition, the use of portfolios in clinical settings raises issues unique to the health care setting such as patient privacy, disclosure of clinical information, and professional liability exposure of physicians. It is not clear that peer-review statutes that sometimes protect educational materials used in teaching and evaluation of residents would also bar disclosure and/or evidentiary use of portfolio contents. Is the teaching institution, resident, or graduate vulnerable to requests and subpoenas for the portfolio contents? If so, then a resident's documentation of insecurities, suboptimal performance, or bad outcomes would be ripe for discovery in a medical malpractice lawsuit. If embraced too quickly and without sufficient reflection on the nuances of implementation, this well-intentioned initiative may present unintended legal consequences.

  8. Past, Present, and Future Production of Bio-oil

    2009-04-01

    Bio-oil is a liquid product produced by fast pyrol-ysis of biomass. The fast pyrolysis is performed by heating the biomass rapidly (2 sec) at temperatures ranging from 350 to 650 oC. The vapors produced by this rapid heating are then condensed to produce a dark brown water-based emulsion composed of frag-ments of the original hemicellulose, cellulose and lignin molecules contained in the biomass. Yields range from 60 to 75% based on the feedstock type and the pyrolysis reactor employed. The bio-oil pro-duced by this process has a number of negative prop-erties that are produced mainly by the high oxygen content (40 to 50%) contributed by that contained in water (25 to 30% of total mass) and oxygenated compounds. Each bio-oil contains hundreds of chemi-cal compounds. The chemical composition of bio-oil renders it a very recalcitrant chemical compound. To date, the difficulties in utilizing bio-oil have limited its commercial development to the production of liq-uid smoke as food flavoring. Practitioners have at-tempted to utilize raw bio-oil as a fuel; they have also applied many techniques to upgrade bio-oil to a fuel. Attempts to utilize raw bio-oil as a combustion engine fuel have resulted in engine or turbine dam-age; however, Stirling engines have been shown to successfully combust raw bio-oil without damage. Utilization of raw bio-oil as a boiler fuel has met with more success and an ASTM standard has recently been released describing bio-oil characteristics in relation to assigned fuel grades. However, commercialization has been slow to follow and no reports of distribution of these bio-oil boiler fuels have been reported. Co-feeding raw bio-oil with coal has been successfully performed but no current power generation facilities are following this practice. Upgrading of bio-oils to hydrocarbons via hydroprocessing is being performed by several organizations. Currently, limited catalyst life is the obstacle to commercialization of this tech-nology.

    We report a new synthesis of best estimates of the inputs of fixed nitrogen to the world ocean via atmospheric deposition and compare this to fluvial inputs and dinitrogen fixation. We evaluate the scale of human perturbation of these fluxes. Fluvial inputs dominate inputs to the continental shelf, and we estimate that about 75% of this fluvial nitrogen escapes from the shelf to the open ocean. Biological dinitrogen fixation is the main external source of nitrogen to the open ocean, i.e., beyond the continental shelf. Atmospheric deposition is the primary mechanism by which land-based nitrogen inputs, and hence human perturbations of the nitrogen cycle, reach the open ocean. We estimate that anthropogenic inputs are currently leading to an increase in overall ocean carbon sequestration of 0.4% (equivalent to an uptake of 0.15 Pg C yr-1 and less than the Duce et al. (2008) estimate). The resulting reduction in climate change forcing from this ocean CO2 uptake is offset to a small extent by an increase in ocean N2O emissions. We identify four important feedbacks in the ocean atmosphere nitrogen system that need to be better quantified to improve our understanding of the perturbation of ocean biogeochemistry by atmospheric nitrogen inputs. These feedbacks are recycling of (1) ammonia and (2) organic nitrogen from the ocean to the atmosphere and back, (3) the suppression of nitrogen fixation by increased nitrogen concentrations in surface waters from atmospheric deposition, and (4) increased loss of nitrogen from the ocean by denitrification due to increased productivity stimulated by atmospheric inputs.

  10. The c-global Revival in Physics (Letters to Progress in Physics

    2015-10-01

    Full Text Available A return is proposed to the 6-years-long period before Einstein gave up on the global constancy of the speed of light c in the vacuum. c-global remains implicit in Maxwell’s equations and in quantum electrodynamics. Reluctantly, Einstein abandoned c-global in 1911 after a 3 1 2 years long silence kept on gravitation during which he had tr ied in vain to avoid the conclusion that c is only an everywhere locally but not a globally valid constant of nature. It is shown that Einstein just overlooked a corollary to his own find- ing of an optically reduced speed of an horizontal light ray downstairs in his constantly accelerating long rocketship in outer space. The new corollary reads: slantedness rela- tive to the tip of the locally horizontal light ray. Hence Einstein’s famous gravitational redshift — the increase in wavelength compared to above of a vertically emitted light ray — is accompanied by a proportional enlargement of space. The new horizontal size increase is masked from above by the upwards slant valid relative to the tip. Einstein’s gravitational time dilation thus goes hand in hand with an equal gravitational space di- lation . Surprisingly, Quantum Mechanics enforces the same conclusion independently: the reduced energy of the locally normal-appearing photons downstairs generates (via Quantum Mechanics’ creation and annihilation operators atoms of a proportionally re- duced mass and hence proportionally enlarged size. Two disappointing implications follow: c-global rules out both cosmological space expansion and black hole evap- oration. The uplifting third implication is: c-global makes the equivalence principle compatible with Quantum Mechanics for the first time. This ne w compatibility pre- dictably extends to the implied “ c-global -rescaled General Relativity”. Hence the “holy grail of physics” is bound to exist. The cgr-GR only waits to be written down.

    The purpose of this paper is to investigate the differential responses of flower opening to ethylene in two cut rose cultivars, 'Samantha', whose opening process is promoted, and 'Kardinal', whose opening process is inhibited by ethylene. Ethylene production and 1-aminocyclopropane-1-carboxylate (ACC) synthase and oxidase activities were determined first. After ethylene treatment, ethylene production, ACC synthase (ACS) and ACC oxidase (ACO) activities in petals increased and peaked at the earlier stage (stage 3) in 'Samantha', and they were much more dramatically enhanced and peaked at the later stage (stage 4) in 'Kardinal' than control during vasing. cDNA fragments of three Rh-ACSs and one Rh-ACO genes were cloned and designated as Rh-ACS1, Rh-ACS2, Rh-ACS3 and Rh-ACO1 respectively. Northern blotting analysis revealed that, among three genes of ACS, ethylene-in- duced expression patterns of Rh-ACS3 gene corresponded to ACS activity and ethylene production in both cultivars. A more dramatic accumulation of Rh-ACS3 mRNA was induced by ethylene in 'Kardinal' than that of 'Samantha'. As an ethylene action inhibitor, STS at concentration of 0.2 mmol/L generally inhibited the expression of Rh-ACSs and Rh-ACO in both cultivars, although it induced the expression of Rh-ACS3 transiently in 'Kardinal'. Our results suggests that 'Kardinal' is more sensitive to ethylene than 'Samantha'; and the changes of Rh-ACS3 expression caused by ethylene might be related to the acceleration of flower opening in 'Samantha' and the inhibition in 'Kardinal'. Additional results indicated that three Rh-ACSs genes were differentially associated with flower opening and senescence as well as wounding

    Full Text Available The Ilan Plain is located at the south western tip of the Okinawa Trough backarc basin, which prop a gates west ward into the Taiwan orogen. From three moderate earthquakes which occurred near the coast line of the Ilan Plain, one of magnitude 6.2 on 15 May 2002 and the other two of magnitudes 5.51 and 5.49 on 5 March 2005, we at tempted to understand the relation ship between the earthquake mechanisms and the geological context. Seven seismic reflection pro files collected roughly parallel to the coast line of the Ilan Plain were used in this work. A structural fault, with a significant normal faulting component trending approximately ENE-WSW, is identified to the east of the doublet earth quakes of 5 March 2005. Be cause this fault follows the ENE-WSW trend of the after shock seismicity, we named it the Ilan Shelf Fault, which might ex tend to the east be yond the Ilan continental shelf spur. How ever, the centroid seismic moment ten sorsolutions for the doublet earth quakes of 5 March 2005 are of a left-lateral strike-slip faulting type which are consistent with onland GPS observations. Hence, the Ilan Shelf Fault may have a left-lateral strike-slip component. Based on GPS data, we suggest that the northern Central Range block, bounded in the west by the Lishan Fault and in the north by the Ilan Shelf Fault, rotates clock wise. This rotation is ascribed to the northwestward collision of the Luzon Arc against Tai wan. Thus, there is a left-lateral strike-slip and an extensional motion along the Ilan Shelf Fault. The northern Central Range block is tilting north ward which may also in duce the normal faulting component of the Ilan Shelf Fault. In short, the Ilan Shelf Fault could be a major tectonic and structural feature bounding the southern end of the Okinawa Trough backarc basin.

  13. THE DEVELOPMENT OF INNOVATIVE DESIGN OF THE CONICAL ROTARY- AND FILM APPARATUS

    Full Text Available Summary. A new design of the conical rotary- and film apparatus for carrying out the process of dripping phosphatidic emulsion of vegetable oils, which are used in the oil industry and other industries that use the evaporation of moisture from the high-heat-labile concentrates. As a result of experimental studies we achieved the following. The conical rotary film apparatus perforated inner cavity of the rotor is divided into a supply and distribution of the original product and vapor removal zone with a barrier that hosts spheroconical insert shapes with reverse bend the conical portion, the top of which is directed towards the delivery of the original product. In the area of supply and distribution of starting material the perforations of the rotor have a slit shape. In the cavity of the rotor curved blades are mounted whose generators have the form of the curve. This curve is obtained by approximation of the polyline. The nozzle for inputting of starting mate-rial having tangentially formed holes on both ends is rotatably mounted in the central part of the conical body along its axis, one end of which is placed in the interior of the perforated rotor in the feeding zone and the distribution of the starting material, and the other one is placed in the chamber for a starting material, which is connected in series with the heater and the feeding pump for starting material. Scientific novelty of the innovative design of the device is to reduce the amplitude of the oscillation of the film rotary apparatus by re-ducing friction of particles suspension on the rotor blades, causing higher dynamic loads, ensure even distribution of starting material on the inner surface of the housing, as well as reduction of energy consumption.

    Seedlings of the popular maize cultivar "Zhengdan-958" growing in pots individually were exposed to suitable soil water conditions as control, light water shortage, moderate water shortage, and severe water shortage, corresponding to soil water contents between 75%-85%, 65%-75%, 55%-65%, and 45%-55% of field water capacity, respectively. Responses of stomatal aperture, Kranz anatomy, and vascular bundle structure to different water contents of maize leaves were investigated. Results showed that under increased water shortages, the levels of H2O2 in both guard cells and subsidiary cells were enhanced, also the fluorescence intensity of H2O2 labeled with fluorescent dye increased, while stomatal aperture and conductance decreased gradually. Moreover, Kranz cells were messily arranged and the cell size became smaller and smaller, and the structure of bundle sheath cells went irregular; and the sectional area of the big bundle and xylem, the cell number of phloem, and the thickness of whole leaf and of upper and lower epidermis reduced. In addition, the number of chloroplasts in mesophyll cells and vascular bundle sheath cells decreased, particularly under the moderate water deficit, chloroplasts in Kranz cells which located in the inside of cytoplasmic membrane and cling on the cell wall spread to the direction of cell center. It demonstrated that stomatal closing of maize could be regulated by H2O2 in guard cells and subsidiary cells together, and H2O2 in subsidiary cells maybe played a cooperative role. In conclusion, under increased soil water shortages, drought-induced H2O2 accumulations in both guard cells and subsidiary cells of maize leaves participated in the regulation of stomatal closing. And, the size of Kranz cells and bundle sheath cells, the cell number of phloem, and the area of the xylem and phloem re- duced, thereby, reducing water shortage-induced damage.

    Computer based automatic medical image processing and quantification are becoming popular in digital pathology. However, preparation of histology slides can vary widely due to differences in staining equipment, procedures and reagents, which can reduce the accuracy of algorithms that analyze their color and texture information. To re- duce the unwanted color variations, various supervised and unsupervised color normalization methods have been proposed. Compared with supervised color normalization methods, unsupervised color normalization methods have advantages of time and cost efficient and universal applicability. Most of the unsupervised color normaliza- tion methods for histology are based on stain separation. Based on the fact that stain concentration cannot be negative and different parts of the tissue absorb different stains, nonnegative matrix factorization (NMF), and particular its sparse version (SNMF), are good candidates for stain separation. However, most of the existing unsupervised color normalization method like PCA, ICA, NMF and SNMF fail to consider important information about sparse manifolds that its pixels occupy, which could potentially result in loss of texture information during color normalization. Manifold learning methods like Graph Laplacian have proven to be very effective in interpreting high-dimensional data. In this paper, we propose a novel unsupervised stain separation method called graph regularized sparse nonnegative matrix factorization (GSNMF). By considering the sparse prior of stain concentration together with manifold information from high-dimensional image data, our method shows better performance in stain color deconvolution than existing unsupervised color deconvolution methods, especially in keeping connected texture information. To utilized the texture information, we construct a nearest neighbor graph between pixels within a spatial area of an image based on their distances using heat kernal in lαβ space. The

    The sea surface microlayer (SML) is a vital environmental boundary involved in Earth's biogeochemical processes, such as heat, gas, and momentum exchange at the air-sea interface (Carlson et al. 1988, Cunliffe et al. 2013, Liss and Duce 2005). Under favorable conditions, natural slicks form on the sea surface and are visible in synthetic aperture radar (SAR) imagery due to the damping of Bragg waves by surfactants. Surface-active agents (surfactants) reside in the SML and associated subsurface water (SSW) and are the byproducts of life processes of marine organisms such as phytoplankton, zooplankton, and seaweed (Gade et al. 2013); the focus of this work is bacteria. A new approach to reduce contamination during sample collection, handling, and lab processing has been further expanded upon and implemented in this study (Kurata et al. 2016, Hamilton et al. 2015). Microlayer and subsurface samples have been collected in the Straits of Florida and the Gulf of Mexico during Radarsat-2 and TerraSAR-X overpasses. As part of the Gulf of Mexico Research Initiative (CARTHE), over 100 samples were collected in the Gulf of Mexico near De Soto Canyon in February 2016. Quantitative PCR (qPCR) analysis of these samples show a wide variability of relative abundance of Bacillus spp., a well-known surfactant-associated bacteria (Satpute et al. 2010), between the SML and SSW. NextGen sequencing (Illuming MiSeq) results will be analyzed to determine exact bacterial community composition of sea surface microlayer and subsurface samples. We plan to expand our observational sites to several locations in the World Ocean.

    2004-05-01

    This presentation reviews current working methods for asteroid occultations developed by the International Occultation Timing Association (IOTA). Reduc- tion of multiple tracks or "chords" observed during stellar occultations pro- vides valuable measures of the relative sizes and shapes of asteroids. Tradi- tionally, predictions for asteroid occultations were prepared by regional IOTA computors, distributed annually in "hard copy" format to IOTA subscrib- ers and in publications such as Sky & Telescope magazine and the annual RASC Observers Handbook. IOTA - like many other organizations - is now using worldwide internet services and e-mail to distribute frequently-updated pre- dictions based upon the latest astrometry. The IOTA web pages provide an easily accessible, centralized source of information on lunar and solar sys- tem occultation events. IOTA's web pages feature a variety of articles on current activities, plans for observing campaigns and expeditions, and "how to do it" information on the latest technology and techniques. The latest up- dated predictions for asteroid events are made available as they are pro- duced, providing more accurate observing tracks and efficient coordination of observers. The IOTA e-mail list provides a dynamic forum for the exchange of technical information and com-munication of observing plans in a timely man- ner. Individuals may now generate customized occultation predictions using the WinOccult software package. The author presents some examples of recent occultation events, showing the benefits of coordinated observations. Also described are some of the latest innovations, featuring low-cost video camera equipment, devices for time insertion based on Global Positioning Satellite (GPS) technology, and a new approach using unattended secondary field station equipment to multiply the number of tracks observed.

    Full Text Available Cooking bananas (Musa spp., ABB genome were intro-duced into Southeastern Nigeria by the International Institute of Tropical Agriculture (IITA in the mid-1980s as an interim measure to reduce the incidence of black sigatoka disease (caused by the fungus Mycosphaerel-la fijiensis Morelet on plantain. However, the people of this region were not familiar with their utilisation methods. To address this lack of the knowledge and thereby sustain cooking banana cultivation, IITA, in collaboration with the Shell Petroleum Development Company (SPDC and the Nigeria Agip OU Company (NAOC commenced a training campaign on cooking banana processing methods. This study examined the patterns of utilisation of cooking bananas ten years after the training took place and compared them with plantain. About 95 % of the households interviewed are consuming cooking banana, indicating a broad acceptance of the crop in the region. Overall, two ripening stages termed green and ripe are the most popular ripening stages for the consumption of both plantain and cooking banana, followed by partially ripe maturity stage. The most common forms of consumption for green plantain are, in decreasing order of importance, pottage, boiled, roasted, and fried. Green cooking banana is also mostly eaten in pottage and boiled forms, and less frequently in fried and pounded forms. Ripe plantain is mostly eaten in fried and pottage forms, while ripe cooking banana is mostly eaten in fried and raw forms. Partially ripe plantain is mostly eaten in pottage, fried, boiled, and roasted forms, while partially ripe cooking banana is eaten in fried, pottage and boiled forms. These results indicate that the consumption patterns of plantain and cooking banana are very similar. This similarity has greatly contributed to the rapid integration of cooking banana within the existing plantain consumption and cropping systems.

    2016-01-01

    Full Text Available Based on the information from the Internet the authors decided to reproduce the possible conditions of landing the plane IL-76TD-90VD in Antarctica in their computer experiment using the mathematical modeling system of aircraft flight dynamics (MMS AFD, which is developed and continuously improved in MSTUCA. MMS AFD has already shown its ability to complete such tasks for different aircraft types in various conditions, including IL-76TD, IL-96-300, IL-96T and also slippery runways.For the computational experiments the information from the web sources was used. The authors did not aim to pro- duce a final numerical results, which describe the possible operating conditions. It was expected only to get accurate qualita- tive results, which can adequately describe the behavior of the airplane IL-76TD-90VD when landing on the slippery runway.So, the authors were able to obtain a typical turn of plane at the end of run and show that the pilot style in these conditions has little effect on the qualitative behavior of the aircraft. The most important factor leading to such maneuvers, lies in the special connection of longitudinal and lateral friction of gear wheels with runway.The authors managed to identify the minimum allowed value of standard friction coefficient of the runway (0,42 which allows a safe landing under crosswind 15 m/s.The results that agree qualitatively with the known situations indicate the possibility for MMS AFD to properly reproduce various cases of aircraft IL-76TD-90VD landing to Antarctica ice airfield and identify any inaccurately knownparameters.

    2016-01-01

    Full Text Available For single-rotor helicopters there are special flight modes, when tail rotor (TR is under significant inductive influ- ence of vortical wake of main rotor (MR. Inductive influence of vortical wake of MR can provoke essential changes in flowing of TR and its aerodynamic characteristics comparing to isolated rotor. In this case increase of tail rotor pitch, nec- essary for helicopter controlling, is possible.The article contains computational modelling of TR work with vortical wake of MR at the example of MIL Mi-171 helicopter. The modelling has been made on the base of non-linear blade (free wake vortical model of rotor, pro- duced at Helicopter Design Department of MAI.Helicopter hovering modes with crosswind of various intensity Vz was considered. Thrust-time relationship forisolated TR and TR with vortical wake of MR for equal flight modes was obtained. Flow around the rotors was analyzed, its vortical wake was considered.The results make it possible to clarify the peculiarities of TR work on considered modes and MR influence on its work. It was found out that vortical wake of MR has a more significant impact on TR work with crosswind on the right, when TR falls into vortex ring state mode. Inductive influence of vortical wake of MR leads to vortexring state mode for TR on lower speeds (Vz :: 5 m/s than in case of isolated work of TR (Vz :: 12,5 m/s. In that case,the required tail rotor pitch has increased by 13% for Vz = 5 m/s. The results of modelling and flight tests led to good agreement.

    Nonsense-mediated mRNA decay (NMD) is a surveillance mechanism that detects and degrades mRNAs containing premature translation termination codons (PTCs). SMG-1 and Upf1 transiently form a surveillance complex termed “SURF” that includes eRF1 and eRF3 on post-spliced mRNAs during recognition of PTC. If an exon junction complex (EJC) exists downstream from the SURF complex, SMG-1 phosphorylates Upf1, the step that is a rate-limiting for NMD. We provide evidence of an association between the SURF complex and the ribosome in association with mRNPs, and we suggest that the SURF complex functions as a translation termination complex during NMD. We identified SMG-8 and SMG-9 as novel subunits of the SMG-1 complex. SMG-8 and SMG-9 suppress SMG-1 kinase activity in the isolated SMG-1 complex and are involved in NMD in both mammals and nematodes. SMG-8 recruits SMG-1 to the mRNA surveillance complex, and inactivation of SMG-8 induces accumulation of a ribosome:Upf1:eRF1:eRF3:EJC complex on mRNP, which physically bridges the ribosome and EJC through eRF1, eRF3, and Upf1. These results not only reveal the regulatory mechanism of SMG-1 kinase but also reveal the sequential remodeling of the ribosome:SURF complex to the predicted DECID (DECay InDucing) complex, a ribosome:SURF:EJC complex, as a mechanism of in vivo PTC discrimination.

    Metaphorically, a teleoperator with master controllers projects the user's arms and hands into a re- mote area, Therefore, human users interact with teleoperators at a more fundamental level than they do with most human-machine systems. Instead of inputting decisions about how the system should func- tion, teleoperator users input the movements they might make if they were truly in the remote area and the remote machine must recreate their trajectories and impedance. This intense human-machine inter- action requires displays and controls more carefully attuned to human motor capabilities than is neces- sary with most systems. It is important for teleoperated manipulators to be able to recreate human trajectories and impedance in real time. One method for assessing manipulator performance is to observe how well a system be- haves while a human user completes human dexterity tasks with it. Fitts' tapping task has been, used many times in the past for this purpose. This report describes such a performance assessment. The International Submarine Engineering (ISE) Autonomous/Teleoperated Operations Manipulator (ATOM) servomanipulator system was evalu- ated using a generic positioning accuracy task. The task is a simple one but has the merits of (1) pro- ducing a performance function estimate rather than a point estimate and (2) being widely used in the past for human and servomanipulator dexterity tests. Results of testing using this task may, therefore, allow comparison with other manipulators, and is generically representative of a broad class of tasks. Results of the testing indicate that the ATOM manipulator is capable of performing the task. Force reflection had a negative impact on task efficiency in these data. This was most likely caused by the high resistance to movement the master controller exhibited with the force reflection engaged. Measurements of exerted forces were not made, so it is not possible to say whether the force reflection helped

    Full Text Available Introduction. Fetomaternal hemorrhage (FMH is a transfu-sion of fetal blood into the maternal circulation. A volume of transfused fetal blood required to cause severe, life-threatening fetal anemia, is not clearly defined. Some authors suggest vol-umes of 80 mL and 150 mL as a threshold which defines mas-sive FMH. Therefore, a rate of massive FMH is 1 : 1,000 and 1 : 5,000 births, respectively. Fetal and neonatal anemia is one of the most serious complications of the FMH. Clinical manifesta-tions of FMH are nonspecific, and mostly it presented as re-duced fetal movements and changes in cardiotocography (CTG. The standard for diagnosing FMH is Kleihaurer-Betke test. Case report. A 34-year-old gravida (G 1, para (P 1 was hospitalized due to uterine contractions at 39 weeks of gesta-tion. CTG monitoring revealed sinusoidal fetal heart rate and clinical examination showed complete cervical dilatation. Im-mediately after admission, the women delivered vaginally. Ap-gar scores were 1 and 2 at the first and fifth minute, respec-tively. Immediately baby was intubated and mechanical ventila-tion started. Initial analysis revealed pronounced acidosis and severe anemia. The patient received intravenous fluid therapy with sodium-bicarbonate as well as red cell transfusion. With all measures, the condition of the baby improved with normaliza-tion of hemoglobin level and blood pH. Kleihaurer-Betke test revealed the presence of fetal red cells in maternal circulation, equivalent to 531 mL blood loss. The level of maternal fetal hemoglobin (HbF and elevated alpha fetoprotein also con-firmed the diagnosis of massive FMH. Conclusion. For the successful diagnosis and management of FMH direct commu-nication between the obstetrician and the pediatrician is neces-sary as presented in this report.

  5. Microbiology of Water and Fluids for Hemodialysis

    Full Text Available In hemodialysis, huge amounts of water are used for diluting the concentrates to produce dialysis fluid. The water is pro-duced on site by reverse osmosis units. The chemical and microbiological quality of the water is essential for dialysis patients. Reverse osmosis units produce water of acceptable chemical quality that can be kept throughout the water system. The microbiological water quality, on the other hand, does not depend on the reverse osmosis unit but on the maintenance of the whole water system. All over the world, dialysis units take water samples and send them to laborato-ries for cultivation and endotoxin tests. Depending on the method of microbiological analysis, the water may be judged to be very good even if in reality it is much worse and outside of standard recommendations. When standardizing the meth-ods with adequate cultivation of water samples, the accuracy of the tests will be better, and as a result, dialysis units can use their resources for keeping the water systems in good shape, i.e. disinfect preventively and frequently and use less effort in collecting samples. This will benefit patients, who will receive a high-quality dialysis fluid, thus eliminating the effects of microbiological impacts such as increased levels of inflammation markers (e.g. C-reactive protein. In the situation of performing hemodiafiltration by producing the substitution fluid “on-line”, it is even more important to have a sensitive method of microbiological verification to follow-up the hygienic quality.

    Full Text Available The response of Taipei basin upon earthquake excitation was studied using records of recent earthquakes. The strong-motion database includes records obtained at 32 stations of the Taipei TSMIP net work from 83 deep and 142 shallow earthquakes (M > 4.0 that occurred in 1992 - 2004. The characteristics of frequency-de pendent site response were obtained as spectral ratios between the actual earthquake records (horizontal components and those modelled for a hypothetical Very Hard Rock (VHR condition. The models for VHR spectra of Taiwan earthquakes had been recently proposed by Sokolov et al. (2005b, 2006. Analysis of site response characteristics and comparison with simple 1D models of the soil column resulted in the following conclusions: (1 The spectral ratios through out the basin obtained from deep earth quakes (depth > 35 km exhibit good agreement with the theoretical ratios calculated using the 1D models constructed using avail able geological and geotechnical data. (2 The spectral ratios obtained from shallow earth quakes show influence of: (a surface waves generated when travelling from distant sources to the basin and (b relatively low-frequency (< 1 - 2 Hz waves generated within the basin. (3 Some shallow earth quakes pro duce extremely high amplification at frequencies 0.3 - 1 Hz within the basin that may be dangerous for high-rise buildings and high way bridges. (4 The obtained results may be used in probabilistic seismic microzonation of the basin when many possible earth quakes located at various distances are considered. 2D and 3D simulation is necessary to model the seismic influence from particularly large earthquakes.

    Piriformospora indica, an endophytic root-colonizing fungus, efficiently promotes plant growth and induces resistance to abiotic stress and biotic diseases. The fungal cell wall extract induces cytoplasmic calcium [Ca2+]cyt elevation in host plant roots. Here, we show that an elici-tor-active cell wall moiety, released by P. indica into the medium, is cellotriose (CT). CT in-duces a mild defense-like response including the production of reactive oxygen species, changes in membrane potentials and the expression of genes involved in growth regulation and root development. CT based [Ca2+]cyt elevation in Arabidopsis roots does not require BAK1 coreceptor, or the putative Ca2+ channels TPC1, GLR3.3, -2.4 and -2.5 and operates synergistically with the elicitor chitin. We identified an ethylmethane-sulfonate-induced mu-tant ([Ca2+]cyt elevation mutant, cycam) impaired in response to CT, cellooligomers (n = 2, 4-7), but not to chitooligomers (n = 4-8) in roots. The mutant contains a single nucleotide ex-change in the gene encoding for a poly(A) ribonuclease (AtPARN, At1g55870) which de-grades poly(A) tails of specific mRNAs. The wild-type PARN cDNA, expressed under the control of a 35S promoter, complements the mutant phenotype. Our finding of cellotriose as a novel chemical mediator might help to understand the complex P. indica-plant mutual rela-tionship in beneficial symbiosis. {copyright, serif} 2018 American Society of Plant Biologists.

    The detection of a large tidal k2 value from Cassini [1] constitutes very strong evi-dence for a subcrustal ocean, most plausibly dominated by water. However, the secondary constituents are not known. One interesting possibility that has received scant attention in analysis of surface data sets is that the ocean contain aqueous ammonium sulfates, which erupted on the surface in the past to create vast, smooth plains [2]. We adopt the hypothesis that the undifferentiated plains—the "bland-lands" in the mid-latitudes of Titan—are these deposits, and test it using radiometry with SAR data. Lopez et al (this conference) investigate the global distribution and possible origin of this type of unit. We extracted SAR and radiometry-during-SAR data sets from the PDS, and pro-duced maps of brightness temperatures. The SAR imagery was used to identify locations where crossovers exist -some of which are in the undifferentiated plains--and hence where brightness temperatures at different incidence angles are available. We derived emissivities from the data using a simple radiometric model [3] to ac-count for the brightness temperature differences as a function of surface roughness, volume scattering and emissivity. We test the hypothesis by assessing whether the derived emissivities and volume scattering in the bland-lands are consistent with the model cryoclastic ash of ice and ammonium sulfate proposed in [2], distinct from that in other terrains.

  9. A synthetic peptide with the putative iron binding motif of amyloid precursor protein (APP does not catalytically oxidize iron.

    Directory of Open Access Journals (Sweden)

    Kourosh Honarmand Ebrahimi

    Full Text Available The β-amyloid precursor protein (APP, which is a key player in Alzheimer's disease, was recently reported to possess an Fe(II binding site within its E2 domain which exhibits ferroxidase activity [Duce et al. 2010, Cell 142: 857]. The putative ligands of this site were compared to those in the ferroxidase site of ferritin. The activity was indirectly measured using transferrin, which scavenges the Fe(III product of the reaction. A 22-residue synthetic peptide, named FD1, with the putative ferroxidase site of APP, and the E2 domain of APP were each reported to exhibit 40% of the ferroxidase activity of APP and of ceruloplasmin. It was also claimed that the ferroxidase activity of APP is inhibited by Zn(II just as in ferritin. We measured the ferroxidase activity indirectly (i by the incorporation of the Fe(III product of the ferroxidase reaction into transferrin and directly (ii by monitoring consumption of the substrate molecular oxygen. The results with the FD1 peptide were compared to the established ferroxidase activities of human H-chain ferritin and of ceruloplasmin. For FD1 we observed no activity above the background of non-enzymatic Fe(II oxidation by molecular oxygen. Zn(II binds to transferrin and diminishes its Fe(III incorporation capacity and rate but it does not specifically bind to a putative ferroxidase site of FD1. Based on these results, and on comparison of the putative ligands of the ferroxidase site of APP with those of ferritin, we conclude that the previously reported results for ferroxidase activity of FD1 and - by implication - of APP should be re-evaluated.

    Full Text Available Elevated productivity of castor and common bean in intercropping is obtained with the use of quality seeds, where boron plays an important role in plant nutrition. The objective of the this study was to evaluate the physiological quality of seeds of the common bean and castor grown in intercropping syste ms, subject to different sources and levels of boron. A completely randomized design was used in a 2 x 5 + 2 facto- rial scheme with four replications. Treatments cons isted of two sources of boron (borax = 11% B and bo ric acid = 17% B, combined with five boron doses (0.0, 0.5, 1.0, 2.0 and 4.0 kg ha -1 of B in the soil in intercropping of the common bean with castor, plus additional treatm ents of common bean and castor in monoculture. It w as concluded that boric acid permitted for acquisition of common bean seeds with the highest germination per- centage when intercropped with castor. Use of the d ose of 1.5 kg ha -1 of boron in the soil resulted in acquisition of seeds of the common bean with vigor of 79% when intercropped with castor, regardless of the boron s ource. Employing 2.3 kg ha -1 of boron, with the source being either boric acid or borax, influenced the vigor of castor seeds produced when intercropped with the common be an. The addition of boron by soil fertilization, in de- pendent of the source used, did not affect the phys iological quality of common bean seeds or castor se eds pro- duced in monoculture.

    While Internet users may often believe they have anonymity online, a culmination of technologies and recent research may allow an adversary to precisely locate an online user s geophysical location. In many cases, such as peer-to-peer applications, an adversary can easily use a target s IP address to quickly obtain the general geographical location of the target. Recent research has scoped this general area to a 690m (0.43 mile) radius circle. In this work, we show how an adversary can exploit Internet communication for geophysical location by embedding covert signals in communication with a target on a remote wireless local area network. We evaluated the approach in two common real-world settings: a residential neighborhood and an apartment building. In the neighborhood case, we used a single-blind trial in which an observer located a target network to within three houses in less than 40 minutes. Directional antennas may have allowed even more precise geolocation. This approach had only a 0.38% false positive rate, despite 24,000 observed unrelated packets and many unrelated networks. This low rate allowed the observer to exclude false locations and continue searching for the target. Our results enable law enforcement or copyright holders to quickly locate online Internet users without requiring time-consuming subpoenas to Internet Service Providers. Other privacy use cases include rapidly locating individuals based on their online speech or interests. We hope to raise awareness of these issues and to spur discussion on privacy and geolocating techniques.

  12. To Speak or Not to Speak: Developing Legal Standards for Anonymous Speech on the Internet

    Directory of Open Access Journals (Sweden)

    Tomas A. Lipinski

    2002-01-01

    Full Text Available This paper explores recent developments in the regulation of Internet speech, in specific, injurious or defamatory speech and the impact such speech has on the rights of anonymous speakers to remain anonymous as opposed to having their identity revealed to plaintiffs or other third parties. The paper proceeds in four sections.  First, a brief history of the legal attempts to regulate defamatory Internet speech in the United States is presented. As discussed below this regulation has altered the traditional legal paradigm of responsibility and as a result creates potential problems for the future of anonymous speech on the Internet.  As a result plaintiffs are no longer pursuing litigation against service providers but taking their dispute directly to the anonymous speaker. Second, several cases have arisen in the United States where plaintiffs have requested that the identity of an anonymous Internet speaker be revealed.  These cases are surveyed.  Third, the cases are analyzed in order to determine the factors that courts require to be present before the identity of an anonymous speaker will be revealed.  The release is typically accomplished by the enforcement of a discovery subpoena instigated by the party seeking the identity of the anonymous speaker. The factors courts have used are as follows: jurisdiction, good faith (both internal and external, necessity (basic and sometimes absolute, and at times proprietary interest. Finally, these factors are applied in three scenarios--e-commerce, education, and employment--to guide institutions when adopting policies that regulate when the identity of an anonymous speaker--a customer, a student or an employee--would be released as part of an internal initiative, but would nonetheless be consistent with developing legal standards.

    Full Text Available The amendments of the wording of chapters 45, 47 and 48 of the RF Criminal Procedure Code (of January, 1, 2013 are estimated. The elimination of indicating the person being under proceeding on taking forced measures of medical character is considered unreasonable. Mentioning a legal representative of civil defendant contravenes the other provisions of the law. The author proves the necessity to mention the judicial decisions which cannot be appealed along with stating the procedure of appealing against judicial decisions. The interpretation of Art. 389 Sec. 2 clause 5 (appeal against the ruling of the RF Supreme Court’s judge should be filed to the RF Supreme Court’s Board of appeals draws some questions. The wording of the Article 389 of the RF Criminal Procedure Code is analyzed. It is proposed to count 10 days since passing the sentence. In case of dissenting opinion (Art. 310 Sec. 5 we should count from the day of its first reading. Conforming of the subpoena for attendance of witnesses, experts and other persons to the judge’s subjective discretion in Art. 389 Sec. 2 is considered inappropriate. The elimination of indicating the replication in appellate debate is unreasonable. The defendant’s pre-imposition statement is improperly referred to debate. The procedural status of a person being under revising the judicial decision is questionable. Other defects of legislative regulation of the appeal proceedings are considered. The author proves the necessity to amend the imperfect chapter 45 of the RF Criminal Procedure Code.

    2017-09-01

    Full Text Available To evaluate the possible range of application of the new InCise2 MLC for the CyberKnife M6 system in brain radiosurgery, a plan comparison was made for 10 brain metastases sized between 1.5 and 9cm3 in 10 patients treated in a single fraction each. The target volumes consist of a PTV derived by expanding the GTV by 1mm and were chosen to have diversity in the cohort regarding regularity of shape, location and the structures needed to be blocked for beam transmission in the vicinity. For each case, two treatment plans were optimized: one using the MLC and one using the IRIS-collimator providing variable circular fields. Plan re-quirements were: dose prescription to the 70% isodose line (18 or 20Gy, 100% GTV coverage, ≥98% PTV coverage, undisturbed central high dose region (95% of maximum dose and a conformity index as low as possible. Plan com-parison parameters were: conformity index (CI, high-dose gradient index (GIH, low-dose gradient index (GIL, total number of monitor units (MU and expected treatment time (TT. For all cases, clinically acceptable plans could be gen-erated with the following results (mean±SD for CI, GIH, GIL, MU and TT, respectively for the MLC plans: 1.09±0.03, 2.77±0.26, 2.61±0.08, 4514±830MU and 27±5min and for the IRIS plans: 1.05±0.01, 3.00±0.35, 2.46±0.08, 8557±1335MU and 42±7min. In summary, the MLC plans were on average less conformal and had a shallower dose gradient in the low dose region, but a steeper dose gradient in the high dose region. This is accompanied by a smaller vol-ume receiving 10Gy. A plan by plan comparison shows that usage of the MLC can spare about one half of the MUs and one third of treatment time. From these experiences and results suggestions for MLC planning strategy can be de-duced.

  15. The Irma-sponge Project Frhymap: Flood Risk and Hydrological Mapping

    Science.gov (United States)

    Hoffmann, L.; Pfister, L.

    In the context of both increasing socio-economic developments in floodplains and the recent heavy floodings that have occurred in the Rhine and Meuse basins, the need for reliable hydro-climatological data, easily transposable hydrological and hydraulic models, as well as risk management tools has increased crucially. In the FRHYMAP project, some of these issues were addressed within a common mesoscale experimen- tal basin: the Alzette river basin, located in the Grand-duchy of Luxembourg. The various aspects concerning flooding events, reaching from the hydro-climatological analysis of field data to the risk assessment of socio-economic impacts, taking into account past and future climate and landuse changes were analysed by the six partici- pating research institutes (CREBS, L; CEREG, F; DLR, D; EPFL, CH; UB, D; VUB, B). Hydro-climatological data analysis over the past five decades has shown that in the study area, the increase in westerly and south-westerly atmospheric circulation patterns induced higher winter rainfall totals, leading to more frequent groundwater resurgences and ultimately also to higher daily maximum streamflow of the Alzette. The thus increased flood hazard has nonetheless a certain spatial variability, closely linked to the rainfall distribution patterns, which are strongly depending on the topo- graphical characteristics of the study area. Although the overall regime of the Alzette is more dependent on climate fluctuations, land use changes (mining activities, urbani- sation) had a marked effect on the rainfall-runoff relationship in some sub-basins over the last decades. By linking model parameters to physiographical basin characteris- tics, regionalised and thus easily transposable hydrological models were developed. Within a study area with very little long-term observation series, this technique, com- bined with the use of hydraulic models, allowed to define hydrological hazard pro- ducing and hydrological risk exposed areas.

    Full Text Available Background: In Anzali Lagoon, there are some endemic and exotic fishes. The present study was conducted to compare the parasitic fauna of Blicca bjeorkna, as an endemic fish and Hemicul­ter leucisculus, as an introduced fish to the lagoon.Methods: A parasitological investigation was done on 78 specimens of B. bjoerkna and 114 of H. leu­cisculus. The fishes were collected from August 2009 to April 2010 by the electro fishing from Anzali Lagoon.Results: Eleven parasites species were found in 192 fish samples. The prevalence and mean inten­sity of parasites in each host were as follows: Parasites from B. bjorkna were Trichodina perforata (53.85%; Myxobolus musayevi (27.19%, 1±0.79; Dactylogyrus difformis (88.05%, 8±7.24 and D. sphyrna (5.18%, 0.95±0.51, Diplostomum spataceum (98.72%, 9.51±9.01, Post­hodiplostomum cuticula (15.38%, 4.25±2.5, Ripidocotyle sp. (1.28%, 2±0.74; Contracaecum osculatum (17.95%, 1.64±0.79, Philometra rischta (12.8%, 1.4±0.54, and Raphidascaris acus (1.04%, 0.03±0.26. The H. leucisculus were infected with T. perforata (27.19%, D. spataceum (7.89%, 1.33±0.54, Ps. tomentosa (7.02%, 1.62±0.49 and R. acus (0.88%, 3±0.28. B. bjoerkna was presented as a new host for M. musayevi and C. osculatum, while H. leucisculus was intro­duced as a new host for T. perforata and Ps. tomentosa.Conclusion: The prevalence of parasites was significantly more in native fish than that of exotic fish (P<0.05. This reduction in parasitic infection in H. leucisculus may be due to its immune system resistance, well adaptation to the new environment, host-specific limitation for endemic parasites and disability of introduced parasite to complete its life cycle in the new host as well.

    2016-04-01

    The IPCC Fifth Assessment Report (AR5) accounts an increase of the total annual anthropogenic GHG emissions between 2000 and 2010 that directly came from the transport sector. In 2010, 14% of GHG emissions were released by transport and fossil-fuel-related CO2 emissions reached about 32 GtCO2 per year. The report also considers adaptation and mitigation as complementary strategies for reducing the risks of climate change for sustainable development of urban areas. This paper describes the on-road traffic emission estimated in the framework of a Sardinian regional project [1] for the town of Sassari (Sardinia, Italy), one of the Sardinian areas where the fuel consumption for on-road transportation purposes is higher [2]. The GHG emissions have been accounted (a) by a calculation-based methodology founded on a linear relationship between source activity and emission, and (b) by the COPERT IV methodology through the EMITRA (EMIssions from road TRAnsport) software tool [3]. Inventory data for annual fossil fuel consumption associated with on-road transportation (diesel, gasoline, gas) have been collected through the Dogane service, the ATP and ARST public transport services and vehicle fleet data are available from the Public Vehicle Database (PRA), using 2010 as baseline year. During this period, the estimated CO2 emissions accounts for more than 180,000 tCO2. The calculation of emissions due to on-road transport quantitatively estimates CO2 and other GHG emissions and represents a useful baseline to identify possible adaptation and mitigation strategies to face the climate change risks at municipal level.

  20. Environmental issues of petroleum exploration and production: Introduction

    Kharaka, Yousif K.; Dorsey, Nancy S.

    2005-01-01

    Energy is the lifeblood of our planet Earth, an essential commod- ity that powers the expanding global economy. Starting in the 1950s, oil and natural gas became the main sources of primary energy for the increasing world population, and this dominance is expected to continue for several more decades (Edwards, 1997; Energy Information Administration (EIA), 2004). In the United States, petroleum production started in 1859 when Drake's well was drilled near Titusville, Pennsylvania, and oil and natural gas currently supply approximately 63% of the energy consumption; forecasts indicate that by 2025, their use will increase by about 40% to 28.3 million bbl/day and to 31.4 tcf/yr (EIA, 2004). The clear benefits of petroleum consumption, however, can carry major environmental impacts that may be regional or global in scale, in- cluding air pollution, global climate change, and oil spills. This vol- ume of Environmental Geosciences, covering environmental impacts of petroleum exploration and production, does not address these major impacts directly because air pollution and global warming are issues related primarily to petroleum and coal uses, and major oil spills are generally attributed to marine petroleum transportation, such as the Exxon Valdez's 1989 spill of 260,000 bbl of oil into Prince William Sound, Alaska. Exploration for and production of petroleum, however, have caused local detrimental impacts to soils, surface and groundwa- ters, and ecosystems in the 36 producing states in the United States (Richter and Kreitler, 1993; Kharaka and Hanor, 2003). These im- pacts arose primarily from the improper disposal of some of the large volumes (presently estimated at 20 billion bbl/yr total pro- duced) of saline water produced with oil and gas, from accidental hydrocarbon and produced-water releases, and from abandoned oil wells that were orphaned or not correctly plugged (Kharaka et al., 1995; Veil et al., 2004).

  1. Long Term Climate Friction For The Earth's Obliquity

    Science.gov (United States)

    Levrard, B.; Laskar, J.

    The lagged response between obliquity variations, the waxing and waning of continen- tal ice sheets, the viscous flow of the mantle and thereby, the total dynamical ellipticity may induce a secular trend in Earth's obliquity (Bills, 1994; Rubincam, 1995; Ito et al, 1995; D.M Williams et al., 1998) though its amplitude and direction are still very controversial and unclear. Previous works predicted a positive drift of 0.04/Ma (Ito et al, 1995) with Late Pleis- tocene glacial conditions, while D.M Williams et al.(1998) proposed a large decrease of 30 during 100 Ma around the Late Precambrian-Cambrian (ca. 550 Ma) bound- ary, favoured by hypothetical huge extented ice cap on a South polar supercontinent, and thus arguing in favor of G.E Williams' high obliquity scenario (1975, 1993) as an explanation of low-latitude Precambrian glaciations. However, theses models have considered the obliquity as the only ice-age driver, while it is admitted that advances and retreats of ice sheets are also driven by others Mi- lankovitch periods, or they have used unrealistic palaeogeographic continental and glacial distributions. We, thus, show that for realistic estimations of theses character- istics, absolute value of the secular drift of obliquity does not exceed 0.01/Ma for the Late Pleistocene and 0.05/Ma for each Neoproterozoic glacial interval. Futher- more, we show that widespread continental glaciations from low to high-latitude dur- ing Varanger glacial interval (ca. 610-570 Ma) on Pannotia supercontinent and low- latitude Sturtian continental glaciations (ca. 750-700 Ma) on an equator-straddling Rodinia supercontinent have probably drifted the obliquity in opposite directions in- ducing a global invariancy of the obliquity during Neoproterozoic Era. "Hard" or "soft" Snowball Earth hypothesis producing global or partial ice-covered oceans and continents would also probably minimize climate friction effect. If we take account of massive and long Permo

This com­pact as­pect re­quires a high av­er­age RF gra­di­ent, with few places that do not have cav­i­ties. Also, the muon beam is dif­fuse and re­quires an RF sys­tem with large trans­verse and lon­gi­tu­di­nal ac­cep­tance. A trav­el­ing wave sys­tem can ad­dress these re­quire­ments.

    To reveal the possible mechanism involved in patella-femoral degenerative arthritis (PFDA) in- duced by torsion-deformity of tibia via analyzing the relationship between torsion-deformity of the tibia in patients with PFDA and the disorder of patella-femoral joint under the static and dynamic conditions. From October 2009 to October 2010, 50 patients (86 knees, 24 knees of male patients and 62 knees of female patients) with PFDA were classified as disease group and 16 people (23 knees, 7 knees of males and 16 knees of females) in the control group. The follow indexes were measured: the torsion-angle of tibia on CT scanning imagings, the patella-femoral congruence angle and lateral patella-femoral angle under static and dynamic conditions when the knee bent at 30 degrees of flexion. Based on the measurement results, the relationship between the torsion-deformity of tibias and the disorders of patella-femoral joints in patients with PFDA were analyzed. Finally,the patients were divided into three groups including large torsion-angle group, small torsion-angle group and normal group according to the size of torsion-angle, in order to analyze the relationship between torsion-deformity and disorders of patella-femoral joint, especially under the dynamic conditions. Compared with patients without PFDA, the ones with PFDA had bigger torsion-angle (30.30 ± 7.11)° of tibia, larger patella-femoral congruence angle (13.20 ± 3.94)° and smaller lateral patella-femoral angle (12.30 ± 3.04)°. The congruence angle and lateral patella-femoral angle under static and dynamic conditions had statistical differences respectively in both too-big torsion-angle group and too-small torsion-angle group. The congruence angle and lateral patella-femoral angle under static and dynamic conditions had no statistical differences in normal torsion-angle group. Torsion-deformity of tibia is the main reason for disorder of patella-femoral joint in the patients with PFDA. Torsion-deformity of

    Next-generation high-temperature thermoelectric-power-generating devices will employ segmented architectures and will have to reliably withstand thermally induced mechanical stresses produced during component fabrication, device assembly, and operation. Thermoelectric materials have typically poor mechanical strength, exhibit brittle behavior, and possess a wide range of coefficient of thermal expansion (CTE) values. As a result, the direct bonding at elevated temperatures of these materials to each other to produce segmented leg components is difficult, and often results in localized microcracking at interfaces and mec hanical failure due to the stresses that arise from the CTE mismatch between the various materials. Even in the absence of full mechanical failure, degraded interfaces can lead to increased electrical and thermal resistances, which adversely impact conversion efficiency and power output. The proposed solution is the insertion of a mechanically compliant layer, with high electrical and thermal conductivity, between the low- and high-temperature segments to relieve thermomechanical stresses during device fabrication and operation. This composite material can be used as a stress-relieving layer between the thermoelectric segments and/or between a thermoelectric segment and a hot- or cold-side interconnect material. The material also can be used as a compliant hot shoe. Nickel-coated graphite powders were hot-pressed to form a nickel-graphite composite material. A freestanding thermoelectric segmented leg was fabricated by brazing the compliant pad layer between the high-temperature p- Zintl and low-temperature p-SKD TE segments using Cu-Ag braze foils. The segmented leg stack was heated in vacuum under a compressive load to achieve bonding. The novelty of the innovation is the use of composite material that re duces the thermomechanical stresses en - countered in the construction of high-efficiency, high-temperature therm - o-electric devices.

    INTRODUCTION    Rehabilitation after coronary revascularization procedures is an intrinsic element of treatment during the in-hospital period. OBJECTIVES    The aim of this study was to compare the course and effects of rehabilitation in patients receiving hybrid or classical treatment during the in-hospital period. PATIENTS AND METHODS    Two hundred patients participating in a prospective, random-ized clinical trial (POLMIDES), that assessed the effect of hybrid treatment on in-hospital outcomes and remote results in patients with multi-vessel coronary artery disease were ana-lysed. Two groups were considered in the trial: a hybrid group (MIDCAB/PCI) and a classical group (CABG/OPCAB). RESULTS    An assessment using the EuroSCORE revealed a higher perioperative risk in clas-sical group. The mean (SD) the EuroSCORE was 2.89 (1.97) vs 3.54 (2.12). During all the monitored rehabilitation cycles, lower arterial blood saturation was reported in the hybrid group (P = 0.002). Lower systolic blood pressure (P <0.001), lower diastolic blood pressure (P = 0.029) and more frequent cases of blood pressure drops during rehabilitation (P = 0.02) were present in the classical group. Patients from the classical group were able to sit (P<0.001), become vertical  (P <0.001) and walk (P = 0.01) earlier than the hybrid group. In the hybrid group (P = 0.001), earlier completion of rehabilitation and discharge from the hos-pital were noted. CONCLUSIONS    In patients from the hybrid treatment group, hypotonia events occurred more rarely, whereas arterial blood saturation values were lower. Mobilization of patients in the two-stage hybrid treatment regimen was slower during the initial days and cycles of reha-bilitation, but patients from this group achieved full self-reliance earlier, which enabled a re-duced hospitalization period.

  14. Shock wave fractionated noble gases in the early solar system

    Many processes in the active star-forming regions are accompanied by strong shock waves, in acceleration by which the nuclear-active particles form the power-law energy spectrum of high rigidity: F(> E0) ˜ Eγ , with the spectral index γ ≤ 1.5-2. It must affect the production rates of spallogenic components of the isotopes, whose excitation functions depend on the shape of the energy spectrum of radiation. Thus, the isotopic signatures formed in the conditions of the strong shock wave propagation must be different from those formed in the calm environment. The early solar system incorporated all the presumed processes of the starforming stage, so that its matter had to conserve such isotopic anomalies. In previous works [1] the shock wave effects in generation of extinct radionu-clides and light elements Li, Be and B were considered. In the report some results for their evidence in the noble gas signatures are presented. Modelling the Kr isotope generation in spallation of Rb, Sr, Y and Zr with the nuclear-active particles, the energy spectrum of which was variable in the range of γ= 1.1-6.0, shows the different pace of growth of abundances of the dif-ferent Kr isotopes with decreasing . It leads to the quite diverse behaviour of the various Kr isotope ratios: the 78,80 Kr/83 Kr ratios increase, and the 82,84,86 Kr/83 Kr ratios decrease for the smaller γ. According to such criteria, for instance, the isotopically heavier SEP-Kr in the lunar ilmenites was pro-duced with the accelerated particles of the more rigid energy spectrum (γ ˜ 2) in comparison with the SW-Kr. Another important feature of the shock wave acceleration of particles is the enrichment of their specrtum with heavier ions in proportion to A/Z. Clearly, the shock wave fractionation of the noble gases, favouring the heavier isotopes, had to be inevitable. Such a fractionation depends on timing episodes of shock wave acceleration: after the n-th act of the ion acceleration their fractionation is

    Full Text Available Asthma is a chronic inflammatory disorder of the airways, associated with airway re-modeling and hyperresponsiveness. It is expressed that asthma influences about 300 million people around the world, which is estimated to increase to about 400 million by 2025. The prevalence rate is 15 to 20 percent in children and 5 to 10 percent in adults, while its trend is still increasing. Inflammation plays an important role in the patho-physiology of asthma, which involves an interaction of different types of the immune cells and mediators. It leads to a number of pathophysiology changes, including bron-chial inflammation, airway obstruction, and clinical episodes such as cough, wheeze and shortness of breath. Asthma is now greatly being introduced as a heterogeneous disorder and it is pointed out to the role of T cells, including Th1, Th2, Th17, and regu-latory T cells. Other immune cells, especially neutrophils, macrophages and dendritic cells, as well structural cells such as epithelial and airway smooth muscle cells also pro-duce disease-associated cytokines in asthma. Increased levels of these immune cells and cytokines have been recognized in clinical samples and mouse models of asthma. Different cytokines, including pro-inflammatory cytokines (such as TNFα, IL-1, and IL-6, T helper 2 cytokines (such as IL-4, IL-5, IL-9, IL-13, and growth factors (such as GM-CSF, PDGF play a role in the pathogenesis of asthma. Indeed chemokines (such as MPC-1, RANTES , MIP-1 and the chemokine receptors (such as CCR3, CCR4, CCL11, CCL24, and CCL26 play an important role in the recruitment of circu-lating inflammatory cells into the airways in asthmatic patients and also is related with increased T helper 2 cytokines after inhaled allergens. Among new approaches, treat-ment of asthma with anti-cytokine drugs such as antibodies blocking IL-4, IL-5, IL-9 could reduce recruitment inflammatory cells into the airways and remodeling.

    processes. Early work by Cauer (1951) had shown that Cl/Na and Cl/Mg ratios were lower in air than in seawater, indicating loss of chlorine by "acid displacement" from sea salt by the strong acids, H2SO4 (Eriksson (1959a, b) and HNO3 (Robbins et al., 1959). Already the first measurements of bromine in aerosols by Duce et al. (1963) showed that bromine, like chlorine, was lost from the sea salt particles, whereas iodine was strongly enriched ( Duce et al., 1965). Research since the early 1980s has shown that photochemical processes are actively involved.Interest in the chemistry of atmospheric halogens took a steep upward surge after it was postulated that the release of industrially produced halocarbons, in particular the chlorofluorocarbons (CFCs), CFCl3, and CF2Cl2, could cause severe depletions in stratospheric ozone (Molina and Rowland, 1974) by the reactions involving the CFC photolytic product radicals, Cl and ClO, as catalysts. The first stratospheric measurements of ClO did indeed show its presence in significant quantities in the stratosphere so that by the end of the 1970s USA, Canada, and the Scandinavian countries issued laws against the use of CFC gases as propellants in spray cans. In the mid-1980s the springtime stratospheric ozone hole over Antarctica was discovered by Farman et al. (1985), involving heterogeneous reactions on polar stratospheric clouds that lead to chlorine activation ( Solomon et al., 1986). Ten years later, in 1996, a complete phaseout ofthe production of the CFCs and a number of other chlorine- or bromine-containing chemicals came into effect for all nations in the developed world. In this contribution we will, however, concentrate on the impact of reactive chlorine, bromine, and iodine on tropospheric ozone chemistry.Halogens have the potential to be important in many facets of tropospheric chemistry. A multitude of gas phase reactions and gas-particle interactions occur that include coupling with the sulfur cycle and reactions with

    pyrolysis of alkanes and alcohols in the presence of perchlorates produced polychlorine containing chloro-alkanes similar to what was observed on Mars. Surpris-ingly, however, similar treatment of acetic acid pro-duced chloroketones, instead, and no chloroalkanes were reported. This suggests that the chloroalkanes detected in the Sheepbed mudstone were not derived from aliphatic carboxylic acids, but instead were from more reduced alcohols or even alkanes, or perhaps were degradation products of more complicated organic material. Because organics analyses on mars will rely heavily on py-GC-MS of perchlorate-containing samples over the next decade, it is important to understand the fate of organic molecules of biotic and abiotic origin under such conditions. In this work we begin a series of experiments to improve our understanding of products generated during py-GC-MS of increasingly complex organic molecules (esters, amides, peptides, nucleic acids, fatty acids) in the presence of perchlorate.

Totodată, creşterea concurenţei în aceste pieţe duce la o creştere şi a riscurilor asumate, de aici şi practica autorităţilor de reglementare de a oferi un rol mai proeminent în reglementarea prudenţială adecvării capitalului.BANKING BUSINESS MODEL - CURRENT TENDENCIESThe modelling of a banking business plan needs to be carried out in tight correlation to the intended management scope, if the manager intends to double profit, he will thus take on a greater risk and if he intends to apply a development strategy starting from the minimization of risks, profits will be smaller but certain.Any entity survives in interdependence with the internal and external environment from which it is part of and therefore a company exists in relation to those surrounding it. From this point of view, two main tendencies may be observed in the development of a business model at the beginning of the XIIth century: the development of a durable business and corporate governance.In order to obtain enhanced efficiency, especially in the integrated markets, like the one which is

    momentum exchange forces and the interphase heat exchanges are 1 treated implicitly to ensure stability. In order to reduce one more time the computa- tional cost, a decomposition of the global domain in N subdomains is introduced and all the previous algorithms applied to one block is performed in each block. At the in- terface between subdomains, an overlapping procedure is used. Another advantage is that different sets of equations can be solved in each block like fluid/structure interac- tions for instance. We show here the hydrodynamics of a two-phase flow in a vertical conduct as in industrial plants of fluid catalytical cracking processes with a complex geometry. With an initial Richardson number of 0.16 slightly higher than the critical Richardson number of 0.1, particles and water vapor are injected at the bottom of the riser. Countercurrents appear near the walls and gravity effects begin to dominate in- ducing an increase of particulate volumic fractions near the walls. We show here the hydrodynamics for 13s. 2

    Full Text Available Se expone un nuevo algoritmo de procesamiento de imágenes para detectar y corregir píxeles anómalos que resalten de manera individual entre sus vecinos en imágenes de una secuencia térmica obtenida a partir de un procedimiento de termografía activa, sin afectar la apariencia global de cada imagen, como ocurre al emplear una estrategia clásica de filtrado espacial. Como resultado principal de este filtrado selectivo, se detectan y reemplazan en un alto porcentaje aquellos píxeles defectuosos de fabricación o por el uso continuo del dispositivo CCD de la cámara infrarroja, lo cual re- duce el riesgo de malas interpretaciones en el análisis posterior. Para el desarrollo y prueba del algoritmo propuesto se utilizaron secuencias de video tomadas con una cámara Cincinnati Electronics de indio-antimonio (InSb para inspeccionar láminas de CFRP (plástico reforzado con fibra de carbono mediante la técnica de termografía activa. Los resultados del algoritmo se comparan con una lista de píxeles defectuosos dada por el fabricante de la cámara, arrojando un porcentaje de coincidencia de alrededor del 70%. El presente trabajo toma relevancia al considerar que en la literatura científica se encuentran muy pocos estudios en este campo, centrándose la mayoría en el preprocesamiento de imágenes astronómicas; además, en Colombia se está en una etapa de introducción creciente de técnicas de evaluación no destructiva por termografía (ENDT en amplios sectores industriales que incluyen generación y transmisión de energía, in- genios azucareros y aeronáutica militar, entre otros.An image processing algorithm detects and replaces abnormal pixels individually, highlighting them amongst their neighbours in a sequence of thermal images without affecting overall texture, like classical filtering does. Bad pixels from manufacture or constant use of a CCD device in an IR camera are thus detected and replaced with a very good success rate

    Full Text Available COMPARATIVES APPROACHES ON THE CONTRIBUTION OF DIRECT INVESTMENTS IN ECONOMY: ROMANIA - MOLDOVA AND OTHER EMERGING COUNTRIES OF CENTRAL AND EASTERN EUROPEThe transition towards a market economy in any country of the world requires a restructuring of economic life. The main task of it is the development of the private sector of national economy which would lead to sustainable economic growth. A long-lasting economic revival is possible only in conditions of increase in investment, of maximal use of production capacities. Any economic growth requires funding, too. Investment financing constitutes a significant step in the investment process whereby financial resources are incorporated in the budget of the investment and may be used for payment in order to achieve a project.  Thus, concluding from the introductory ideas of the article, the author proposes to develop a comparative approach of the impact of direct investments in economy of Romania, Republic of Moldova and other emergent countries from Europe. What is certain is that the international measurement and comparison scale of the impact of the foreign direct investment (FDI on economic development is a complicated exercise, taking into consideration the very limited statistical data volume. However, the author manages to draw some conclusions concerning the process of achievement foreign direct investments.ABORDĂRI COMPARATIVE PRIVIND CONTRIBUŢIA INVESTIŢIILOR DIRECTE ÎN ECONOMIE: ROMÂNIA – REPUBLICA MOLDOVA ŞI ALTE ŢĂRI EMERGENTE DIN EUROPA CENTRALĂ ŞI ORIENTALĂÎn orice ţară a lumii, tranziţia spre economia de piaţă impune o restructurare a vieţii economice.

    expected NE-SW and SE-NW structural trends and it has been designed to get 2D/3D images of the crustal structure at a regional scale. A denser 2D network of 35 OBSs has been deployed in the bay of Pozzuoli aimed at detecting and modeling reflected/converted waves from 1 the possible shallow to deep discontinuities beneath the Campi Flegrei caldera. The main target of this particular receiver lay-out is the detailed imaging of the magma chamber top, expected at 4-5 km depth, according to temperature measurements in wells and sparse seismic observations. About 5000 shots have been performed dur- ing the SERAPIS experiment, at an average spatial spacing of 125 m, for a total ship travel path of 620 km. All of the seismic lines have been re-sampled at least twice, using a staggered configuration, which results in a smaller source spacing (less than 65m). In the gulf of Pozzuoli the source array had a geometry of a 5x5 km grid, slightly shifted south with respect to the OBS array. Seismic signals produced by air- guns have been well detected up to 50-60 km distance and the whole Campi Flegrei, Ischia and Procida on-land networks have recorded high quality seismograms pro- duced by the gridded source array in the bay of Pozzuoli. Due to the extended and very dense source and receiver arrays used for SERAPIS, this campaign can provide an innovative contribution to the accurate reconstruction of the Campi Flegrei caldera structure and to the definition of its feeding system at depth. *SERAPIS group: Auger Emmanuel, Bernard Marie-Lise, Bobbio Antonella, Bonagura Mariateresa, Cantore Luciana, Convertito Vincenzo, D'Auria Luca, De Matteis Raffaella, Emolo Anto- nio, Festa Gaetano, Gasparini Paolo, Giberti Grazia, Herrero Andre, Improta Luigi, Lancieri Maria Flora, Nielsen Stefan, Nisii Vincenzo, Russo Guido, Satriano Clau- dio, Simini Mariella, Vassallo Maurizio, Bruno Pier Paolo, Buonocunto Ciro, Capello Marco, Del Pezzo Edoardo, Galluzzo Danilo, Gaudiosi Germana, Giuliana Alessio

  7. Zero in on Key Open Problems in Automated NMR Protein Structure Determination

    KAUST Repository

    Abbas, Ahmed

    2015-11-12

    Nuclear magnetic resonance (NMR) is one of the main approaches for protein struc- ture determination. The biggest advantage of this approach is that it can determine the three-dimensional structure of the protein in the solution phase. Thus, the natural dynamics of the protein can be studied. However, NMR protein structure determina- tion is an expertise intensive and time-consuming process. If the structure determi- nation process can be accelerated or even automated by computational methods, that will significantly advance the structural biology field. Our goal in this dissertation is to propose highly efficient and error tolerant methods that can work well on real and noisy data sets of NMR. Our first contribution in this dissertation is the development of a novel peak pick- ing method (WaVPeak). First, WaVPeak denoises the NMR spectra using wavelet smoothing. A brute force method is then used to identify all the candidate peaks. Af- ter that, the volume of each candidate peak is estimated. Finally, the peaks are sorted according to their volumes. WaVPeak is tested on the same benchmark data set that was used to test the state-of-the-art method, PICKY. WaVPeak shows significantly better performance than PICKY in terms of recall and precision. Our second contribution is to propose an automatic method to select peaks pro- duced by peak picking methods. This automatic method is used to overcome the limitations of fixed number-based methods. Our method is based on the Benjamini- Hochberg (B-H) algorithm. The method is used with both WaVPeak and PICKY to automatically select the number of peaks to return from out of hundreds of candidate peaks. The volume (in WaVPeak) and the intensity (in PICKY) are converted into p-values. Peaks that have p-values below some certain threshold are selected. Ex- perimental results show that the new method is better than the fixed number-based method in terms of recall. To improve precision, we tried to eliminate false peaks using

The decrease of the oxidation rate enhances the formation of Fe 3+ , which in a self-amplifying combination of processes re- duces the oxidation rate even further. In conclusion, the deviations from the FC theory at T temperatures: the system is not a model system for the theory. Summary 165 Neither is the oxidation of Fe(100) in H2O vapor. The measurements presented in chapters 6 (room temperature) and 7 (temperature depen- dence) revealed that during the oxidation in H2O at room temperature, hydrogen is taken up, probably as OH groups in the oxide layer. The oxi- dation rate in H2O which is 3 orders of magnitude lower than the oxidation rate in O2, is entirely determined by the earlier mentioned surface processes: the oxidation could be completely described with a nucleation and growth model containing rate equations for the surface reactions. The oxidation rate reaches a maximum at T = 340K (67 degrees C). Below this temperature, H2 desorption (from H atoms at the surface) determines the oxidation rate. Above 340K, the decrease of the oxidation rate is due to the recombina- tion of OH and H at the surface and subsequent desorption of H2O. The rate limiting step is the dissociation of OH at step edges. Further evidence for this model is formed by the oxidation rate of Fe(100) covered with N marker atoms, which were found to facilitate the nucleation and growth of the oxide islands. Experiments where H2O was replaced with D2O revealed a distinct isotope effect, which is due to a dierent energy barrier for one of the surface processes, but possibly also due to a lower exponential prefac- tor (in an Arrhenius description of rate constants) corresponding to a lower molecular vibration frequency in the D2O molecule or OD surface species (compared with H2O of OH, respectively). Again, the differences could be explained completely by surface processes. The transport properties of the oxide layers formed in H2O at room

    tested by five librarians from the aforementioned list, and slight changes had been made to clarify questions and instructions. Survey respondents were given an initial deadline of February 1, 2006, but responses were received and included through March 13, 2006. Various tactics were used to boost response rates, including electronic discussion list announcements, usage of pre-addressed stamped return envelopes, usage of personalized address information and a personal signature by the researcher on the cover letter, reminder postcards, and a coupon for free ice cream. One hundred and fifty-one questionnaires were returned. Two questionnaires were returned incomplete, and were removed from both the target population and the responses, leaving a total of 149 out of 211 possible responses and a response rate of 71%. For this response rate, all calculations were determined to have a margin of error of +/-4.4% with 95% confidence. The survey was constructed to address five research questions, as detailed below:1 How many requests for personally identifiable patron information have libraries received in the past year, and from whom did those inquiries come?2 How many libraries have a written confidentiality policy, and what are the characteristics of libraries and library directors that have policies?3 How current are those policies?4 How many policies prohibit release of patron information without acourt order or other binding legal document (e.g., subpoena or search warrant? How many policies call for attorney review of any such court orders or other binding legal documents?5 Do librarians support the idea of strengthening the state law relating to confidentiality of library records?The questions were closed-ended in order to allow responses to be coded and easily analyzed, although space was provided forrespondents to offer additional comments. Though a deadline of February 1, 2006 was set, responses were received as late as March 13, 2006. Person’s chi-square and Fisher

    the first academic supervisors in studies of Chornobyl health effects and got professor certificates in this new area. First PhD theses were successfully passed by Dr. E. Gorbov, and Dr. of Sciences - by Dr. D. Bazyka. Basics of future aca demic research directions were elaborated that time by Drs. O. Kovalenko, Zh. Minchenko, V. Talko, I. Holyavka, D. Belyi, D. Yakimenko, E. Mikhai lovska, V. Malyzhev, V. Sushko, A. Cheban, K. Lo ganovsky, K. Bruslova, I. Dyagil, T. Liubarets, O. Kucher, G. Chobotko, and others. Later the major ity of these studies formed a background for Chornobyl legislation, regulatory directives, pre sented as dissertations.A quarter of century passed. The Center as a part of the National Academy of Medical Sciences resisted the challenges and moved forward, was recognized worldwide and fulfilled its main mission - providing highly qualified health care to radiation exposed. Staff numbers decreased (1,091), but work amount has increased. Since 2000, new premises were installed - a hospital with the biggest in Ukraine outpatient clin ic, new laboratory facilities, the last of which was in troduced in 2013. The Academy became a national one and since 2011 the Center was recognized as a national research institution (NRCRM), staff mem bers received 3 State Awards of Ukraine in the Field of Science and Technology, numerous personal awards.During this period, NRCRM staff conducted and published priority research data on radiation risks and molecular mechanisms of leukemia, including chronic lymphocytic, myelodysplastic syndrome, multiple myeloma, thyroid cancer, breast cancer in Chornobyl accident cleanup workers. Studies of the mechanisms of non tumor pathology - cardio vascular, cerebrovascular, cognitive disorders are in process. Of high importance are studies of possible transgenerational effects of radiation. The devel oped new technologies and protocols for the advanced care of radiation exposed were intro duced to the general health care system
