    Shields, D.R.; Wendt, R.L.; Johnson, B.A.

    1982-12-01

    This report summarizes existing technology for mooring components which may be suitable for OTEC use. Due to the platform size, depth of water, and length of design life required for an operational OTEC plant, only large and high capacity mooring components were investigated. The report contains engineering, test, and manufacturer's data on wire rope, synthetic rope (nylon, polyester and Kevlar), anchors, deck fittings and machinery, and design concepts for tension leg platform mooring systems. A significant portion of the effort was directed to the assessment of synthetic rope technology and its application to moorings.

    Ocean Renewable Power Company's OCGen Module Mooring Project provided an extensive research, design, development, testing and data collection effort and analysis conducted with respect to a positively buoyant, submerged MHK device secured to the seabed using a tensioned mooring system. Different analytic tools were evaluated for their utility in the design of submerged systems and their moorings. Deployment and testing of a prototype OCGen® system provided significant data related to mooring line loads and system attitude and station keeping. Mooring line loads were measured in situ and reported against flow speeds. The Project made a significant step in the development of designs, methodologies and practices related to floating and mooring of marine hydrokinetic (MHK) devices. Importantly for Ocean Renewable Power Company, the Project provided a sound basis for advancing a technically and commercially viable OCGen® Power System. The OCGen® Power System is unique in the MHK industry and, in itself, offers distinct advantages of MHK devices that are secured to the seabed using fixed structural frames. Foremost among these advantages are capital and operating cost reductions and increased power extraction by allowing the device to be placed at the most energetic level of the water column.

    2010-07-01

    Charlotte Moore Sitterly was a scientist in an era when it was rare for a woman to have the opportunity to devote her life to forefront science. Following her graduation from Swarthmore College in 1920, she accepted a position at Princeton University as an assistant to Henry Norris Russell. In 1925 she started a study of the solar spectrum. She could then not know that she would devote much of her scientific career to gathering basic atomic data that are invaluable to the scientific community, even today. In 1931 she obtained a Ph.D. degree at the University of California, Berkeley, and returned to Princeton as a staff member of the Princeton University Observatory. In 1945 Moore moved to the National Bureau of Standards (NBS), to supervise preparation of the widely-used tables of atomic energy levels. Following the successful launching (1946) of a V2 rocket to obtain the ultraviolet spectrum of the Sun, she started working also with Richard Tousey and his group at the Naval Research Laboratory (NRL). Ultimately, they extended the solar spectrum down to 2200 angstroms. She continued her affiliations with both the NBS and the NRL until her death in 1990. Charlotte Moore was a rare scientist who devoted her career to obtaining accurate numbers, thus enabling the scientific community to open her tables and know that the data are reliable.

  6. Dynamic analysis of moored tankers

    SciTech Connect

    Dercksen, A.

    1995-12-31

    A loaded 200 kDWT tanker moored, in shallow water, by means of a single bow anchor chain is subjected to wind and waves. Wind loads on the tanker were measured in a stiff mooring arrangement. The measured wind loads together with the calibrated wave train were used as input to a numerical model to predict the dynamic behavior of the anchored tanker. A good correlation with the measured tanker motions and mooring loads was found. The model can be used in the design of mooring systems and anchoring equipment for arbitrary water depths. Important features which are accounted for include bottom friction, low and high frequency tanker motions and chain dynamics.

  7. New mooring chain designs

    1996-12-31

    The present work introduces the readers to the developments the high technology offshore chain industry has carried out in recent years, in an effort to offer products that meet the needs of petroleum exploration and production. In this manner the industry can continue to regard chain as a fundamental element in its moorings system, whether for projects with a 25 year life, or projects at depths of over 1,000 meters, or in such severe environments as those faced in the Sub-Arctic. Data are presented on Studless Chain and VGW or Variable Geometry and Weight chain. These will allow engineers designers to forget the needs for chains to be circumscribed to rigid guidelines of geometry or dimensions. Instead they can design mooring systems specific for the particular situations they face. No longer shall chain have to meet geometric standardization derived from the middle of the 19th century while meeting the requirements of the 2nd half of the 20th century.

  8. Moored offshore structures - evaluation of forces in elastic mooring lines

    NASA Astrophysics Data System (ADS)

    Crudu, L.; Obreja, D. C.; Marcu, O.

    2016-08-01

    In most situations, the high frequency motions of the floating structure induce important effects in the mooring lines which affect also the motions of the structure. The experience accumulated during systematic experimental tests and calculations, carried out for different moored floating structures, showed a complex influence of various parameters on the dynamic effects. Therefore, it was considered that a systematic investigation is necessary. Due to the complexity of hydrodynamics aspects of offshore structures behaviour, experimental tests are practically compulsory in order to be able to properly evaluate and then to validate their behaviour in real sea. Moreover the necessity to carry out hydrodynamic tests is often required by customers, classification societies and other regulatory bodies. Consequently, the correct simulation of physical properties of the complex scaled models becomes a very important issue. The paper is investigating such kind of problems identifying the possible simplification, generating different approaches. One of the bases of the evaluation has been found consideringtheresults of systematic experimental tests on the dynamic behaviour of a mooring chain reproduced at five different scales. Dynamic effects as well as the influences of the elasticity simulation for 5 different scales are evaluated together. The paper presents systematic diagrams and practical results for a typical moored floating structure operating as pipe layer based on motion evaluations and accelerations in waves.

    Booth, Charles R.; Mitchell, B. Greg; Holm-Hansen, O.

    1987-01-01

    Biospherical Instruments has successfully completed a NASA sponsored SBIR (Small Business Innovational Research Program) project to develop spectroradiometers capable of being deployed in the ocean for long periods of time. The completion of this project adds a valuable tool for the calibration of future spaceborne ocean color sensors and enables oceanographers to extend remote sensing optical techniques beyond the intermittent coverage of spaceborne sensors. Highlights of the project include two moorings totalling 8 months generating extensive sets of optical, biological, and physical data sets in the ocean off La Jolla, California, and a 70 day operational deployment of the resulting commercial product by the ONR and NASA sponsored BIOWATT program. Based on experience gained in these moorings, Biospherical Instruments has developed a new line of spectroradiometers designed to support the oceanographic remote sensing missions of NASA, the Navy, and various oceanographers.

  5. The Cole-Moore Effect: Still Unexplained?

    PubMed

    Hoshi, Toshinori; Armstrong, Clay M

    2015-10-01

    In the first issue, on the first page of the Biophysical Journal in 1960, Cole and Moore provided the first confirmation of the Hodgkin and Huxley formulation of the sodium and potassium conductances that underlie the action potential. In addition, working with the squid giant axon, Cole and Moore noted that strong hyperpolarization preceding a depolarizing voltage-clamp pulse delayed the rise of the potassium conductance: once started, the time course of the rise was always the same but after significant hyperpolarization there was a long lag before the rise began. This phenomenon has come to be known as the Cole-Moore effect. Their article examines and disproves the hypothesis that the lag reflects the time required to refill the membrane with potassium ions after the ions are swept out of the membrane into the axoplasm by hyperpolarization. The work by Cole and Moore indirectly supports the idea of a membrane channel for potassium conductance. However, the mechanism of the Cole-Moore effect remains a mystery even now, buried in the structure of the potassium channel, which was completely unknown at the time.

    A compliant mooring to collect high frequency turbulence data at a tidal energy site is evaluated in a series of short demon- stration deployments. The Tidal Turbulence Mooring (TTM) improves upon recent bottom-mounted approaches by suspend- ing Acoustic Doppler Velocimeters (ADVs) at mid-water depths (which are more relevant to tidal turbines). The ADV turbulence data are superior to Acoustic Doppler Current Profiler (ADCP) data, but are subject to motion contamination when suspended on a mooring in strong currents. In this demonstration, passive stabilization is shown to be sufficient for acquiring bulk statistics of the turbulence, without motion correction. With motion cor- rection (post-processing), data quality is further improved; the relative merits of direct and spectral motion correction are dis- cussed.

    Ross, J.M.; Wood, W.A.

    1981-10-01

    The mooring system for a floating OTEC platform consists of a seafloor foundation, a platform foundation, and a connecting line. This paper introduces the OTEC mooring system with a brief historical overview, reviews developmental work accomplished during the past year, and then presents a new look at life cycle costs for an example mooring system. Since June 1980, a significant effort within the OTEC Program has been directed toward the further development of mooring systems. The effort has included work leading to a better understanding of anchoring capabilities and problems, refinement of an existing mooring analytical model, a review of OTEC past mooring designs, and the production of a mooring system technology development plan. A major finding of the past year was a new upward estimate of mooring system lifetime costs as a result of downward-revised estimates of wire rope service life.

    The number, structure, and physical state of the microbial communities in high-moor and low-moor peat bogs were compared. Distinct differences in these characteristics were revealed. The microbial biomass in the high-moor peat exceeded that in the low-moor peat by 2-9 times. Fungi predominated in the high-moor peat, whereas bacteria were the dominant microorganisms in the low-moor peat. The micromycetal complexes of the high-moor peat were characterized by a high portion of dark-colored representatives; the complexes of the low-moor peat were dominated by fast-growing fungi. The species of the Penicillum genus were dominant in the high-moor peat; the species of Trichoderma were abundant in the low-moor peat. In the former, the bacteria were distinguished as minor components; in the latter, they predominated in the saprotrophic bacterial complex. In the high-moor peat, the microorganisms were represented by bacilli, while, in the low-moor peat, by cytophages, myxobacteria, and actinobacteria. The different physiological states of the bacteria in the studied objects reflecting the duration of the lag phase and the readiness of the metabolic system to consume different substrates were demonstrated for the first time. The relationships between the trophic characteristics of bacterial habitats and the capacity of the bacteria to consume substrates were established.

Options for the mooring system include the turret, jacket, and buoy single-point mooring (SPM) systems as well as the spread mooring system. There is no one options which is a one-fit-all agenda for the mooring system. Other generalized conclusions are also presented.

  2. Moore v. Regents of the University of California.

    PubMed

    1988-07-21

    In 1976, John Moore had his spleen removed in the course of treatment for hairy cell leukemia at the UCLA Medical Center. Subsequently, a cell line was developed from Moore's tissues that offered enormous therapeutic value. Doctors applied for patents on the cell line and entered into contracts for its commercial exploitation. Moore claimed the modified tissue to be his own property and sued to recover deserved profits. The trial court dismissed Moore's case because it failed to set forth a proper claim at law. The appellate court reversed, interpreting the claim to be adequate for recovery. The court held that the removed tissue was Moore's property; that consent forms signed by Moore only applied to the removal of tissue and did not imply his consent to its commercial exploitation; and that Moore need not allege either the defendent's knowledge of the cells' value, or of the defendant's intent to exploit the cells, in order to assert his claim.

    Moore's Law states that the processing power of microchips doubles every one to two years. This observation might apply to the nascent field of molecular computing, in which biomolecules carry out logical operations. Incorporation of new technologies that improve sensitivity and throughput has increased the complexity of problems that can be addressed. It is an ultimate goal for molecular computers to use the full potential of massive parallelism.

    2012-06-01

    In the past 46 years, Intel Moore observed an exponential doubling in the number of transistors in every 18 months through the size reduction of individual transistor components since 1965. In this paper, we are exploring the nanotechnology impact upon the Law. Since we cannot break down the atomic size barrier, the fact implies a fundamental size limit at the atomic or Nanotechnology scale. This means, no more simple 18 month doubling as in Moore's Law, but other forms of transistor doubling may happen at a different slope in new directions. We are particularly interested in the Nano enhancement area. (i) 3-D: If the progress in shrinking the in-plane dimensions (2D) is to slow down, vertical integration (3D) can help increasing the areal device transistor density and keep us on the modified Moore's Law curve including the 3rd dimension. As the devices continue to shrink further into the 20 to 30 nm range, the consideration of thermal properties and transport in such nanoscale devices becomes increasingly important. (ii) Carbon Computing: Instead of traditional Transistors, the other types of transistors material are rapidly developed in Laboratories Worldwide, e.g. IBM Spintronics bandgap material and Samsung Nano-storage material, HD display Nanotechnology, which are modifying the classical Moore's Law. We shall consider the overall limitation of phonon engineering, fundamental information unit 'Qubyte' in quantum computing, Nano/Micro Electrical Mechanical System (NEMS), Carbon NanoTubes (CNTs), single layer Graphemes, single strip Nano-Ribbons, etc., and their variable degree of fabrication maturities for the computing and information processing applications.

    Dr. Charlotte Moore Sitterly was a scientist in an era when it was rare for a woman to have the opportunity to devote her life to forefront science. Following her graduation from Swarthmore College in 1920, she accepted a position at Princeton University as an assistant to Henry Norris Russell. In 1925 she started a study of the solar spectrum. She could then not know that she would devote much of her scientific career to gathering basic atomic data that are invaluable to the scientific community, even today. In 1931 she obtained a PhD degree at U. California, Berkeley, and returned to Princeton as a staff member of the Princeton University Observatory. In 1945 she moved to the National Bureau of Science (NBS), to supervise preparation of the widely used tables of atomic energy levels. Following the successful lunching (1946) of a V2 rocket to obtain the ultra violet spectrum of the sun, Moore started working with Richard Tousey and his group at the Naval Research Laboratory (NRL). Ultimately, they extended the solar spectrum down to 2200 angstroms. She continued her affiliations with NBS and NRL until her death in 1990. Charlotte Moore was rare scientist who devoted her career to obtaining accurate numbers, thus enabling the scientific community to open her tables and know that the data are accurate.

    The dynamic responses of mooring line serve important functions in the station keeping of a floating wind turbine (FWT). Mooring line damping significantly influences the global motions of a FWT. This study investigates the estimation of mooring line damping on the basis of the National Renewable Energy Laboratory 5 MW offshore wind turbine model that is mounted on the ITI Energy barge. A numerical estimation method is derived from the energy absorption of a mooring line resulting from FWT motion. The method is validated by performing a 1/80 scale model test. Different parameter changes are analyzed for mooring line damping induced by horizontal and vertical motions. These parameters include excitation amplitude, excitation period, and drag coefficient. Results suggest that mooring line damping must be carefully considered in the FWT design. PMID:25243231

    Permanent boat moorings have contributed to the decline of seagrasses worldwide, prompting the development of 'seagrass-friendly' moorings. We contrasted seagrass cover and density (predominantly Posidonia australis) in the vicinity of three mooring types and nearby reference areas lacking moorings in Jervis Bay, Australia. We examined two types of 'seagrass-friendly' mooring and a conventional 'swing' mooring. 'Swing' moorings produced significant seagrass scour, denuding patches of ~9 m radius. Seagrass-friendly 'cyclone' moorings produced extensive denuded patches (average radius of ~18 m). Seagrass-friendly 'screw' moorings, conversely, had similar seagrass cover to nearby reference areas. Our findings reinforce previous work highlighting the negative effects of 'swing' and 'cyclone' moorings. In contrast, the previously unstudied 'screw' moorings were highly effective. We conclude that regular maintenance of moorings and the monitoring of surrounding seagrass are required to ensure that 'seagrass-friendly' moorings are operating effectively. This is important, as following damage Posidonia will take many decades to recover.

  11. Mooring Design for the Floating Oscillating Water Column Reference Model

    Brefort, Dorian; Bull, Diana L.

    2014-09-01

    To reduce the price of the reference Backward Bent Duct Buoy (BBDB), a study was done analyzing the effects of reducing the mooring line length, and a new mooring design was developed. It was found that the overall length of the mooring lines could be reduced by 1290 meters, allowing a significant price reduction of the system. In this paper, we will first give a description of the model and the storm environment it will be subject to. We will then give a recommendation for the new mooring system, followed by a discussion of the severe weather simulation results, and an analysis of the conservative and aggressive aspects of the design.

  12. Effect of mooring line arrangement on the dynamics of spread mooring systems

    1995-12-31

    A design methodology is formulated to reveal the dependence of nonlinear slow motion dynamics of Spread Mooring Systems (SMS) on mooring line arrangement. For a given SMS configuration, catastrophe sets are developed in the parametric design space showing the dependence of stability boundaries and singularities of bifurcations on design variables. This approach eliminates the need for nonlinear simulations. For general SMS design, however, the designer relies on experience rather than scientific understanding of SMS nonlinear dynamics, due to the high number of design variables. Several numerical applications are used to demonstrate counter intuitive ways of improving SMS dynamics. The SMS design methodology formulated in this paper aims at providing fundamental understanding of the effects of mooring line arrangement and pretension on SMS horizontal plane dynamics. Thus, the first guidelines are developed to reduce trial and error in SMS design. The methodology is illustrated by comparing catastrophe sets for various SMS configurations with up to three mooring lines. Numerous examples for a barge and a tanker SMS which exhibit qualitatively different nonlinear dynamic behavior are provided.

  9. Preliminary investigations into mooring forces on a semisubmersible and a turret moored tanker in pack ice, current and waves

    SciTech Connect

    Murray, J.J.; Spencer, D.

    1996-12-01

    Physical model tests were carried out on a scale model of a semisubmersible and a monohull tanker in drifting pack ice. The tests covered a range of drift velocities, directions and ice concentrations. The models were tested in both a fully restrained and moored condition. Data from the experiments were used to develop a semi-empirical numerical model to predict maximum global loads on the mooring system. These results were compared with the maximum loads on the mooring system caused by hydrodynamic forces (waves and current) predicted from a linear numerical model for waves. Analysis results showed that the maximum mooring loads due to the pack ice on the semisubmersible were considerably higher than those caused by the hydrodynamic forces on the same vessel. Also, the maximum mooring loads due to pack ice on the tanker were close to the maximum mooring loads caused by the hydrodynamic forces. Maximum mooring loads related to pack ice forces were realized in ice concentrations of 10/10 coverage while for concentrations less than 6/10 coverage loads attributed to pack ice were negligible in comparison to the hydrodynamic forces. The paper also presents a number of recommendations, based on these findings, to improve the performance of both vessel types and to advance the general state-of-the-art for analysis procedures related to offshore vessel moored in pack ice.

    Thompson, Thomas W.

    Henry (Hank) J. Moore, a member of the AGU Planetary Sciences section, died of a heart attack on September 21, 1998. He was in Utah while on a family trip to visit his daughter. His 70th birthday occurred just 3 weeks before his death. Henry, who was born in Albuquerque, New Mexico, took great pride in having found and visited the small town of Albuquerque in the Extremadura region of Spain, noting the geologic similarities between that part of Spain and his birthplace in America.Henry, known for his contributions to the Apollo,Viking, Magellan, and Mars Pathfinder missions, attributed his career to a chance encounter with Gene Shoemaker in 1960. Henry was completing his Ph.D. work in geology at Stanford University and Gene obviously had spotted Henry's keen analytical mind. I suspect this pivotal meeting was far from a chance encounter.

  11. Extending the Capabilities of the Mooring Analysis Program: A Survey of Dynamic Mooring Line Theories for Integration into FAST: Preprint

    SciTech Connect

    Masciola, M.; Jonkman, J.; Robertson, A.

    2014-03-01

    Techniques to model dynamic mooring lines come in various forms. The most widely used models include either a heuristic representation of the physics (such as a Lumped-Mass, LM, system), a Finite-Element Analysis (FEA) discretization of the lines (discretized in space), or a Finite-Difference (FD) model (which is discretized in both space and time). In this paper, we explore the features of the various models, weigh the advantages of each, and propose a plan for implementing one dynamic mooring line model into the open-source Mooring Analysis Program (MAP). MAP is currently used as a module for the FAST offshore wind turbine computer-aided engineering (CAE) tool to model mooring systems quasi-statically, although dynamic mooring capabilities are desired. Based on the exploration in this manuscript, the lumped-mass representation is selected for implementation in MAP based on its simplicity, computational cost, and ability to provide similar physics captured by higher-order models.

  12. Evolutionary ethics from Darwin to Moore.

    Evolutionary ethics has a long history, dating all the way back to Charles Darwin. Almost immediately after the publication of the Origin, an immense interest arose in the moral implications of Darwinism and whether the truth of Darwinism would undermine traditional ethics. Though the biological thesis was certainly exciting, nobody suspected that the impact of the Origin would be confined to the scientific arena. As one historian wrote, 'whether or not ancient populations of armadillos were transformed into the species that currently inhabit the new world was certainly a topic about which zoologists could disagree. But it was in discussing the broader implications of the theory...that tempers flared and statements were made which could transform what otherwise would have been a quiet scholarly meeting into a social scandal' (Farber 1994, 22). Some resistance to the biological thesis of Darwinism sprung from the thought that it was incompatible with traditional morality and, since one of them had to go, many thought that Darwinism should be rejected. However, some people did realize that a secular ethics was possible so, even if Darwinism did undermine traditional religious beliefs, it need not have any effects on moral thought. Before I begin my discussion of evolutionary ethics from Darwin to Moore, I would like to make some more general remarks about its development. There are three key events during this history of evolutionary ethics. First, Charles Darwin published On the Origin of the Species (Darwin 1859). Since one did not have a fully developed theory of evolution until 1859, there exists little work on evolutionary ethics until then. Shortly thereafter, Herbert Spencer (1898) penned the first systematic theory of evolutionary ethics, which was promptly attacked by T.H. Huxley (Huxley 1894). Second, at about the turn of the century, moral philosophers entered the fray and attempted to demonstrate logical errors in Spencer's work; such errors were alluded

  14. Moore's Law, disruptive technologies, and the clinician.

    Vosburgh, Kirby G; Newbower, Ronald S

    2002-01-01

    The advancement of technical power described by Moore's Law offers great potential for enabling more cost-effective medical devices and systems. However, progress has been slow. Many factors for this failure have been cited, including the anti-rational economic structure of healthcare and the complexity and long time scale of medical development. Christensen et al. suggest that "disruptive technologies" may circumvent some of these difficulties. "Disruptive Technologies" are defined as those that are established in one market, but then penetrate and overwhelm another market. These incursions are accelerated by economic factors, and capitalize on functionality, reliability, and advancements supported by the original market. Christensen has cited many examples from industrial and service businesses, but few examples can be found yet in healthcare. We argue that positive technology impacts in medicine occur most readily when innovators augment the skills of and collaborate with caregivers, rather than seeking to displace them. In the short term, a new approach may improve efficiency or quality. In the longer term, such approaches may obviate human tasks at lower-skill levels, and even permit task automation. One successful example has been the introduction of flexible monitoring for physiologic information. Systems for computer-aided diagnosis, which have failed to impact complex decision making, have succeeded in simpler specialty areas such as the interpretation of EKG's and mammograms, and may do the same with analysis of some pathology images. The next frontier may the operating room, and the adoption of such systemic technologies by caregivers in emergency medicine and general care may then have an even wider "disruptive" effect. Responding to time and cost pressures, and the desire to move care to the patient, other workers, such as radiologists, will drive the trend away from isolated, complex, large-scale devices, and toward integrated, modular, and simpler

    James Moores Ball (1862-1929) was an ophthalmologist in St. Louis, Missouri, who excelled as a medical historian and collector of rare and historic books about the history of anatomy. During his lifetime, he was best known as the author of a comprehensive, authoritative, and popular textbook titled Modern Ophthalmology First published in 1904, there were five further editions. Ball was very interested in the history of anatomy and wrote two books on this subject, the first being a biography of Andreas Vesalius, one of the earliest in English, and the second a history of the resurrection men or grave robbers who sold corpses to professors of anatomy and surgery for teaching purposes. His legacy today is the 470 volumes of his personal library, which are now in the Archives and Rare Books department of the Becker Medical Library of the Washington University School of Medicine. These texts are one of their major collections, concentrating on the history of anatomy, beginning with a first edition of Vesalius's De Humani Corporis Fabrica and holding many important and beautiful landmark volumes of anatomical atlases.

    2015-03-01

    We study a quantum Hall bilayer system of bosons at total filling fraction ν = 1, and analyze the the coupled Moore-Read state [PRL 108, 256809 (2012)] that results from the interplay between short-ranged interactions and interlayer pair-tunneling terms. Supported by the exact solution of the full zero-energy quasihole spectrum and a conformal field theory analysis, we develop an intuitive picture of this system as two coupled composite fermion superconductors. In this language, pair tunneling plays the role of Josephson coupling between the superconducting phases of the two layers, which gaps out the Goldstone mode associated with interlayer particle distribution. This coupling further implies that non-Abelian quasiparticles are confined between the layers. In the bulk, the resulting phase has the topological order of the Halperin 220 state i.e. U(1)2 x U(1)2 but the edge spectrum at a fixed particle number reveals an unexpected U(1)4 x U(1) structure. We attribute this behavior to the fact that this state is realized in a rotated basis of layer index, where the charged and neutral sectors are separated. With the charge quantum number being conserved but without any such restriction on the neutral sector we show that the edge spectrum must take the observed form.

    We study a quantum Hall bilayer system of bosons at total filling factor ν =1 , and study the phase that results from short-ranged pair tunneling combined with short-ranged interlayer interactions. We introduce two exactly solvable model Hamiltonians which both yield the coupled Moore-Read state [Phys. Rev. Lett. 108, 256809 (2012), 10.1103/PhysRevLett.108.256809] as a ground state, when projected onto fixed particle numbers in each layer. One of these Hamiltonians describes a gapped topological phase, while the other is gapless. However, on introduction of a pair-tunneling term, the second system becomes gapped and develops the same topological order as the gapped Hamiltonian. Supported by the exact solution of the full zero-energy quasihole spectrum and a conformal field-theory approach, we develop an intuitive picture of this system as two coupled composite fermion superconductors. In this language, pair tunneling provides a Josephson coupling of the superconducting phases of the two layers, and gaps out the Goldstone mode associated with particle transport between the layers. In particular, this implies that quasiparticles are confined between the layers. In the bulk, the resulting phase has the topological order of the Halperin 220 phase with U(1)2× U (1)2 topological order, but it is realized in the symmetric/antisymmetric basis of the layer index. Consequently, the edge spectrum at a fixed particle number reveals an unexpected U(1)4× U (1) structure.

    Charles B. Moore passed away 2 March 2010 at the age of 89, following a long and varied scientific career in meteorology and the atmospheric sciences. He will be remembered best for his substantial contributions in the field of atmospheric electricity and for the students and faculty he guided as chairman of Langmuir Laboratory for Atmospheric Research and professor of physics at the New Mexico Institute of Mining and Technology. He possessed a unique sense of humor and an excellent memory that served as a reservoir of scientific and historical knowledge. Like many of his generation, Charlie's career was profoundly influenced by the Second World War. Following Pearl Harbor, he interrupted his undergraduate studies in chemical engineering at Georgia Institute of Technology to enlist in the Army Air Corps, where he became the chief weather equipment officer in the 10th Weather Squadron, setting up and operating remote meteorological stations behind enemy lines in the China-Burma-India theater. He served with distinction alongside Athelstan Spilhaus Sr., who had been one of Charlie's instructors in the Army meteorology program.

    A simple method is presented, that permits to calculate the slow-drift damping induced by mooring lines. It is based on a linearization of the catenary line equations. Comparisons are made with experimental results, and with values obtained with a fully non linear code, with a good agreement. An application case is then presented for a storage barge in the Gulf of Guinea, where it is found that mooring lines bring the dominant contribution to the low-frequency damping.

  2. MITESS: a moored in situ trace element serial sampler for deep-sea moorings

    We have designed, constructed and tested a trace element clean sampling device for long term deployment (6 months or longer) on deep-sea moorings. The device collects unfiltered 500 ml samples by opening and closing a bottle originally filled with dilute acid (passively replaced by denser seawater). Each sample is collected by an independent module, so failure of a single unit does not affect others. Seven years of deployments have refined the sampler into a rugged and reliable device. The device also can be hung below a wire to collect water column samples. Automated trace element sampler (ATE), a spinoff from moored in situ trace element serial sampler, is a single-module device for allowing trace metal clean near-surface samples to be collected by personnel not trained in trace element sampling. ATE/VANE, another variation, allows the same personnel to collect upper water column profiles on conventional hydrowire. The systems have been tested by comparing samples collected for lead and iron with those collected by previously proven sampling techniques.

    Quantitative studies focusing on the collection of semibuoyant fish eggs, which are associated with a pelagic broadcast-spawning reproductive strategy, are often conducted to evaluate reproductive success. Many of the fishes in this reproductive guild have suffered significant reductions in range and abundance. However, the efficiency of the sampling gear used to evaluate reproduction is often unknown and renders interpretation of the data from these studies difficult. Our objective was to assess the efficiency of a modified Moore egg collector (MEC) using field and laboratory trials. Gear efficiency was assessed by releasing a known quantity of gellan beads with a specific gravity similar to that of eggs from representatives of this reproductive guild (e.g., the Arkansas River Shiner Notropis girardi) into an outdoor flume and recording recaptures. We also used field trials to determine how discharge and release location influenced gear efficiency given current methodological approaches. The flume trials indicated that gear efficiency ranged between 0.0% and 9.5% (n = 57) in a simple 1.83-m-wide channel and was positively related to discharge. Efficiency in the field trials was lower, ranging between 0.0% and 3.6%, and was negatively related to bead release distance from the MEC and discharge. The flume trials indicated that the gellan beads were not distributed uniformly across the channel, although aggregation was reduced at higher discharges. This clustering of passively drifting particles should be considered when selecting placement sites for an MEC; further, the use of multiple devices may be warranted in channels with multiple areas of concentrated flow.

Ben was born 18 March 1921, in Kansas City, Missouri, to Fraser D. and Cora R. (Hawkins) Moore. Though his parents provided a strong guiding influence on Ben's development, Ben's career was impacted most clearly by his work as a student and research assistant for Allen Basset (Ben's father-in-law) at Park College. This relationship turned Ben's early interest in chemistry and biology toward a focus on physics. Ben received his undergraduate degree from Park College where he graduated Phi Delta Kappa. He received a MS in physics from Kansas State University. He also did post-masters work at the University of Kansas, the University of Colorado, the University of Washington and Temple University. In addition to his work as a research assistant, Ben taught at Park College as well as Washington Kansas High School, Wyandotte High School, and Kansas City Kansas Junior College before moving to St. Cloud State University in 1960. He retired from this teaching position in May 1982 but remained involved in activities of his department, including some teaching, through most of his years in retirement. Ben's accomplishments were mainly centered on his teaching. His development of courses and his rapport with students consistently brought praise from both his colleagues and his students. Above all, his work involved innovative development of the curriculum in the sciences at St. Cloud State. Soon after his arrival at the university, Ben took over the fledgling field geology course and continued to shape this offering into a program in earth sciences. The popularity of his classes, which attracted both general students and a growing number of majors, finally enabled the university to establish an earth sciences department in the late 1960's and Ben was the first chair of that department.

    Boating activities are one of the causes that threaten seagrass meadows and the ecosystem services they provide. Mechanical destruction of seagrass habitats may also trigger the erosion of sedimentary organic carbon (Corg) stocks, which may contribute to increasing atmospheric CO2. This study presents the first estimates of loss of Corg stocks in seagrass meadows due to mooring activities in Rottnest Island, Western Australia. Sediment cores were sampled from seagrass meadows and from bare but previously vegetated sediments underneath moorings. The Corg stores have been compromised by the mooring deployment from 1930s onwards, which involved both the erosion of existing sedimentary Corg stores and the lack of further accumulation of Corg. On average, undisturbed meadows had accumulated ~6.4 Kg Corg m(-2) in the upper 50 cm-thick deposits at a rate of 34 g Corg m(-2) yr(-1). The comparison of Corg stores between meadows and mooring scars allows us to estimate a loss of 4.8 kg Corg m(-2) in the 50 cm-thick deposits accumulated over ca. 200 yr as a result of mooring deployments. These results provide key data for the implementation of Corg storage credit offset policies to avoid the conversion of seagrass ecosystems and contribute to their preservation. PMID:26979407

    2005-12-01

    We test the impact of assimilating PIRATA mooring temperature and salinity data in the new version of the operational MERCATOR model (PSY1V2 system). The ten PIRATA moorings are situated in the tropical Atlantic, between 15°N and 10°S, and data are collected in real time and provided by the CORIOLIS project. Two run experiments were performed, one assimilating altimetric data and all available in situ data (the operational system) and a second one assimilating the same data set but the PIRATA mooring data. The operational system is sensitive to assimilating PIRATA data in the tropics, on the temperature and salinity profiles as well as on the current fields. Global statistical analyses have been used to estimate the reduction of the biases between prevision model and observations. The impact of PIRATA data is positive in the equatorial band where the equatorial thermocline is better simulated (in term of position and temperature gradient). It is also positive in all layers between surface and 500 meters except in the near surface layer (0-30m) where other assimilated data are more numerous and where the impact of mooring data is probably less sensitive. Direct comparisons with ADCP current moorings are also shown. The comparison is encouraging with significant correlations, even though the time series are limited in time and space.

    Moore's Law (Moore's Observation) has been driving the progress in semiconductor technology for the past 50 years. The semiconductor industry is at a juncture where significant increase in manufacturing cost is foreseen to sustain the past trend of dimensional scaling. At N10 and N7 technology nodes, the industry is struggling to find a cost-friendly solution. At a device level, technologists have come up with novel devices (finFET, Gate-All-Around), material innovations (SiGe, Ge) to boost performance and reduce power consumption. On the other hand, from the patterning side, the relative slow ramp-up of alternative lithography technologies like EUVL and DSA pushes the industry to adopt a severely multi-patterning-based solution. Both of these technological transformations have a big impact on die yield and eventually die cost. This paper is aimed to analyze the impact on manufacturing cost to keep the Moore's law alive. We have proposed and analyzed various patterning schemes that can enable cost-friendly scaling. We evaluated the impact of EUVL introduction on tackling the high cost of manufacturing. The primary objective of this paper is to maintain Moore's scaling from a patterning perspective and analyzing EUV lithography introduction at a die level.

    DeBenedictis, Erik P.

    2004-07-01

    It seems well understood that supercomputer simulation is an enabler for scientific discoveries, weapons, and other activities of value to society. It also seems widely believed that Moore's Law will make progressively more powerful supercomputers over time and thus enable more of these contributions. This paper seeks to add detail to these arguments, revealing them to be generally correct but not a smooth and effortless progression. This paper will review some key problems that can be solved with supercomputer simulation, showing that more powerful supercomputers will be useful up to a very high yet finite limit of around 1021 FLOPS (1 Zettaflops) . The review will also show the basic nature of these extreme problems. This paper will review work by others showing that the theoretical maximum supercomputer power is very high indeed, but will explain how a straightforward extrapolation of Moore's Law will lead to technological maturity in a few decades. The power of a supercomputer at the maturity of Moore's Law will be very high by today's standards at 1016-1019 FLOPS (100 Petaflops to 10 Exaflops), depending on architecture, but distinctly below the level required for the most ambitious applications. Having established that Moore's Law will not be that last word in supercomputing, this paper will explore the nearer term issue of what a supercomputer will look like at maturity of Moore's Law. Our approach will quantify the maximum performance as permitted by the laws of physics for extension of current technology and then find a design that approaches this limit closely. We study a 'multi-architecture' for supercomputers that combines a microprocessor with other 'advanced' concepts and find it can reach the limits as well. This approach should be quite viable in the future because the microprocessor would provide compatibility with existing codes and programming styles while the 'advanced' features would provide a boost to the limits of performance.

    This note describes a profiling mooring with an interdisciplinary suite of sensors taking profiles between 180 and 30 m depth. It consists of an underwater winch, moored below 180 m depth, and a profiling instrumentation platform. In its described setup it can take about 200 profiles at pre-programmed times or intervals with one set of batteries. This allows for studies over an extended period of time (e.g. two daily profiles over a time of 3 months). The Gotland Deep Environmental Sampling Station (GODESS) in the Eastern Gotland Basin of the Baltic Sea is aimed at investigations of redoxcline dynamics. The described system can be readily adapted to other research foci by changing the profiling instrumentation platform and its payload.

    In 1939, Frederick R. Thompson of New York and Austin T. Moore of South Carolina separately developed replacements for the entire ball of the hip. These were used to treat hip fractures and also certain arthritis cases. This type of hemiarthroplasty addressed the problem of the arthritic femoral head only. The diseased acetabulum (hip socket) was not replaced. This prosthesis consisted of a metal stem that was placed into the marrow cavity of the femur, connected in one piece with a metal ball fitted into the hip socket. Bohlman and Austin T. Moore (1939) collaborated for the fabrication and implantation of a custom made 12-inch-long vitallium (metal alloy invented by Venable) femoral head prosthesis for a patient with a recurrent giant cell tumour. This prosthesis functioned well and later on influenced the development of long stem femoral head prostheses.

    In this article I critically examine Adam Moore's claim that the threshold for overriding intangible property rights and privacy rights is higher, in relation to genetic enhancement techniques and sensitive personal information, than is commonly suggested. I argue that Moore fails to see how important advances in genetic research are to social justice. Once this point is emphasized one sees that the issue of how formidable overriding these rights are is open to much debate. There are strong reasons, on grounds of social justice, for thinking the importance of such rights is likely to be diminished in the interests of ensuring a more just distribution of genes essential to pursuing what John Rawls calls a person's 'rational plan of life'.

    2014-10-01

    A tethered asteroid sample and mooring system is investigated in this paper. In this system the spacecraft is moored to the surface of an irregular asteroid such as 216 Kleopatra by using a rocket-propelled anchor with a cable. The rocket-propelled anchor is a kind of space penetrator, which can inject into asteroids at high speeds generated by its own rocket engine. It can be used to explore the interior structure of asteroids, and it can also be used as a sample collector. When the sampling mission is done, the sample can be pulled back to the spacecraft with the anchor. Using this method, the spacecraft can be kept in a safe region in which it cannot be trapped by the gravitational field of the asteroid. This work is concerned with the dynamics of the tethered system near irregular asteroids. First, a shape model and gravitational field model of irregular asteroids are built. Then, the configuration and the stability of the tethered system are investigated, and the quasi-periodic motion near the equilibrium point of the tethered system is analyzed. Finally, the non-uniform density distribution of the asteroids is considered. The deployment process and the oscillation of the tethered system in the uncertain asteroid gravity field are simulated using the Monte Carlo method. The feasibility of the tethered asteroid sample and mooring system is proved.

    The Single Point Mooring Systems (SPM) are widely used as a tanker terminal in Brazilian south coast by Petrobras, Brazilian oil company. Although different authors (Wichers, 1987, Obokata, 1987, and Jiang et al., 1988) had analyzed the dynamic stability of SPM system, the down time of these systems due to large oscillatory ship motion in the horizontal plane is significant until now. The main source of the instability of these systems is considered to be the use of inadequate hawser length and bad weather. This paper deals with the dynamic behavior of SPM moored vessels considering the influence of the environmental forces as well as shallow water effects. In a first step, a nonlinear mathematical model developed for the simulation of low speed ship maneuvers (Takashina, 1986) is extended to study the behavior of a tanker moored to a single buoy in comparison with the Obokata`s SPM model, 1987. A large number of tanker motion simulations were carried out both for deep and shallow water and different environmental conditions. The influence of the system parameters shown by the study is, in general, in a good agreement with those obtained by the traditional SPM system analysis.

    1980-06-01

    Asphaltite is present in facies of the Red Cave and Panhandle lime Formation. Drill cuttings from 30 Moore County wells and 4 cores distributed across Moore and Potter Counties were examined for asphaltite. Results show that asphaltite is widespread but seems to be most abundant over structural highs, and that there is a facies control of asphaltite occurrences. In drill cuttings sandstones contain most abundant nodules yet the nodules are generally very small. Largest nodules were commonly observed in mudstone core samples. A potential exploration program should take those observations into account. Once exploitable deposits are located and if proper in situ leaching materials were developed for extraction of uranium, only sandstones could be worked. Interchannel mudstones are too impermeable and nonporous. Subsurface mining would be forced to address potential problems derived from high concentrations of hydrocarbons in the target rocks (Red Cave Formation produces oil and gas in Moore County) as well as high levels of radon (averages 100 x 10/sup -12/ curies per liter STP) in gas produced from the Panhandle Field.

    Installation of the Auger TLP was completed in February 1994 with first production in April 1994. The lateral mooring system (LMS) was critical to the successful mating of the hull and deck and installation of the tendons. The LMS is currently used to position the TLP over the wells during drilling operations and to assist the tendons in holding station during storm events. This paper describes the most significant lessons learned during design, fabrication, installation and operation of the LMS. The results presented in this paper will be useful to mooring system designers, component manufacturers, installation contractors and other operators pursuing floating system options for development of deepwater fields. Specific results to be addressed include design criteria, component selection, corrosion protection systems, component manufacture, anchor performance, locked coil failures, buoy pin procedures and offshore operations. The most significant aspect of this paper will be to provide the industry with the key learnings from the Auger LMS so that deepwater mooring systems may be further improved for future applications.

    The influence that factors such as mooring line conditions, fender arrangements, dolphin arrangements, degree of ship loading, waves of long period, wave direction, and wind on the impact energy of a moored tanker were studied. Based on systematic test data, a semi-empirical formula was developed to calculate the impact energy of the moored ship on the berthing facilities under the action of regular waves. It was shown by experiment that this method is suitable for calculating the impact energy of moored ships of capacities as great as 200 X 10/sup 3/ t.

Paniccia, who is director of Intel's Photonics Technology Laboratory in Santa Clara, California, ticks off his group's accomplishments: silicon lasers; high-speed silicon modulators; fast, sensitive silicon photodetectors in the infrared. "We have got beyond the proof-of-principle stage," he says. "Now we're putting it all together so that Moore's law can extend for decades into the future."

  11. Patrick Moore's millennium yearbook : the view from AD 1001

    Moore, Patrick, Chapman, Allan

    In a year that will probably be remembered almost as much for books about the millennium as for the turn of 2000 A.D itself, Patrick Moore's Millennium Yearbook celebrates.....well, the wrong millennium! This thoroughly entertaining book - which is for everyone, not just astronomers - contains articles on King Alfred's chronological work, reviews of the new Star Catalogue by the Arab Al-Sufi and the latest edition of Ptolemy's Almagast. And foreshadowing the change to metric units by 1000 years, the book uses arabic numbers instead of Roman - but there is a conversion table if you have trouble with the idea of "zero" and prefer the older system.

  12. Cabled-observatory Regional Circulation Moorings on the Endeavour segment of the Juan de Fuca Ridge

    NASA Astrophysics Data System (ADS)

    Mihaly, S. F.

    2011-12-01

    In September of 2010, one of four moorings was deployed on the Endeavour node of the NEPTUNE Canada cabled-observatory network. The installation included the laying of a 7km cable from the node to the mooring site in the axial valley about 3km north of the Main Endeavour Vent Field over extraordinary bathymetry. This September, three more cables and secondary junction boxes will be deployed to support the three additional moorings that complete the regional circulation array. The cable-laying is facilitated by the Canadian Scientific Submersible Facility's ROV ROPOS and a remotely operated cable-laying system, whereas the actual deployment of the moorings is a two ship operation. The CCGS John P. Tully lowers the mooring anchor first, while the RV Thomas G. Thompson supports the ROV operations which navigate the mooring to underwater mateable cable end. Precise navigation is needed because there are few areas suitable for placement of the junction boxes. Scientifically, the moorings are designed and located to best constrain the hydrothermally driven circulation within the rift valley, the regional circulation can then be used as a proxy measurement for hydrothermal fluxes. Each mooring carries a current meter/ ctd pair at 4, 50, 125, and 200m, with an upward looking ADCP at 250m. The northern moorings are located between the Hi-Rise and Salty Dawg fields about 700m apart in the ~1km wide rift valley and the southern moorings are located south of the Mothra vent field. Here we present initial results from the four mooring array.

  13. Tender mooring for infill drilling operations: A case study

    SciTech Connect

    1997-04-01

    The Tapis-pump platform is a four-leg jacket structure located 230 ft south of the Tapis-D platform and connected to it by a walkway bridge. All crude production (360,000 B/D) from Esso Production Malaysia Inc. (EPMI) wells in the South China Sea offshore Terengganu is piped to the Tapais-pump platform for pumping to an onshore terminal. The continuous operation of this platform is essential. The Tapis-D platform is a manned production platform that also acts as a central communication center and emergency response command center for EPMI`s offshore operations in the South China Sea. A total of nine wells is planned for an infill drilling program at the Tapis-D platform. The rig selected for this infill drilling program is a self-erecting tender-assisted rig that uses an eight-point wire rope mooring system. Eleven pipelines are connected to the Tapis-pump/Tapis-D platform complex. All the pipelines were laid on the seafloor without any special external protection and were not tied down or anchored. The paper describes the planning of the mooring system for drilling.

    Samuel Preston Moore was trained as a military surgeon in the US Army but resigned his commission and was appointed Surgeon-General of the Confederate States Army Medical Department at the beginning of the American Civil War. He reformed the mediocre medical corps by raising recruiting standards and improving treatment protocols and by placing the most capable surgeons in positions of authority. He improved the ambulance corps and directed the construction of many new hospitals for Confederate casualties. He was directly responsible for the barracks hospital design, which is still used today. He established the Confederate States Medical and Surgical Journal and directed a successful effort to develop substitutes for scarce pharmaceuticals from the indigenous flora of the South. He founded the Association of Army and Navy Surgeons of the Confederate States of America. With skill and dedication, Dr. Moore transformed the medical corps into one of the most effective departments of the Confederate military and was responsible for saving thousands of lives on the battlefield.

  9. Transaction Performance vs. Moore's Law: A Trend Analysis

    NASA Astrophysics Data System (ADS)

    Nambiar, Raghunath; Poess, Meikel

    Intel co-founder Gordon E. Moore postulated in his famous 1965 paper that the number of components in integrated circuits had doubled every year from their invention in 1958 until 1965, and then predicted that the trend would continue for at least ten years. Later, David House, an Intel colleague, after factoring in the increase in performance of transistors, concluded that integrated circuits would double in performance every 18 months. Despite this trend in microprocessor improvements, your favored text editor continues to take the same time to start and your PC takes pretty much the same time to reboot as it took 10 years ago. Can this observation be made on systems supporting the fundamental aspects of our information based economy, namely transaction processing systems?

  13. Parallel finite element simulation of mooring forces on floating objects

    NASA Astrophysics Data System (ADS)

    Aliabadi, S.; Abedi, J.; Zellars, B.

    2003-03-01

    The coupling between the equations governing the free-surface flows, the six degrees of freedom non-linear rigid body dynamics, the linear elasticity equations for mesh-moving and the cables has resulted in a fluid-structure interaction technology capable of simulating mooring forces on floating objects. The finite element solution strategy is based on a combination approach derived from fixed-mesh and moving-mesh techniques. Here, the free-surface flow simulations are based on the Navier-Stokes equations written for two incompressible fluids where the impact of one fluid on the other one is extremely small. An interface function with two distinct values is used to locate the position of the free-surface. The stabilized finite element formulations are written and integrated in an arbitrary Lagrangian-Eulerian domain. This allows us to handle the motion of the time dependent geometries. Forces and momentums exerted on the floating object by both water and hawsers are calculated and used to update the position of the floating object in time. In the mesh moving scheme, we assume that the computational domain is made of elastic materials. The linear elasticity equations are solved to obtain the displacements for each computational node. The non-linear rigid body dynamics equations are coupled with the governing equations of fluid flow and are solved simultaneously to update the position of the floating object. The numerical examples includes a 3D simulation of water waves impacting on a moored floating box and a model boat and simulation of floating object under water constrained with a cable.

  14. Results from a winter 2009-2010 nearshore mooring test in 25 m water depth off Newport, Oregon

    NASA Astrophysics Data System (ADS)

    Dever, E. P.; Waldorf, B. W.; Risien, C. M.

    2010-12-01

    As part of the NSF-funded Ocean Observatories Initiative (OOI), two surface moorings will be placed in 25 m water depth off Newport, Oregon and Grays Harbor, Washington. These moorings are intended to acquire continuous observations over the inner-shelf, where the surface boundary layer interacts continuously with the ocean bottom boundary layer. The moorings will utilize the WHOI-developed stretch hose technology implemented at several operational moorings along the US east coast. For the purposes of mooring survival, the largest significant waves need to be considered. Analysis of the historical record indicates the 100-year return period storm would generate 14.5 m high waves. The harsh wind and wave conditions encountered over the inner-shelf have the potential to cause mooring failure either by destroying surface buoy components, or by causing subsurface mooring components to fail. For example, during a winter storm in December 2007, several NDBC moorings along the Oregon and Washington coasts broke. To test modeling of mooring performance under winter conditions we constructed a test/pilot mooring with hardware, communications and power similar to the OOI buoy design. The test focused on the survivability of components. The mooring was equipped with a load cell to examine responses under varying wave and mean flow conditions. A secondary objective of the deployment was to test Ship-to-Ship/Ship-to-Shore Wireless Access Protocol (SWAP) telemetry from the buoy to shore over a distance of 1.5 km. Load cell data as well as buoy instruments (conductivity, temperature) were telemetered. This test mooring was deployed near one of the OOI sites in 25 m of water off Newport, Oregon in late October 2009. The mooring parted in mid-March 2010, two weeks prior to planned recovery. We recovered all mooring components, and we will report on the mooring design, the test, and the science and engineering data received.

  15. Optimization and automation of the semi-submersible platforms mooring design

    1994-12-31

    There are a few calculation programs around the world used for determining the main aspects of the Mooring Design of Semi-Submersible Platforms . These programs bold a worldwide acknowledgement and their results are actually reliable. But they require many runs to get a solution that comply with the Classification Society requirements. This paper presents some procedures in order to optimize the semi-submersible mooring design as well as to make it automatic. Regarding the optimization philosophies, the following aspects are treated: (1) the optimization of the platform heading and the mooring pattern based on the spreading of the environmental forces; (2) the searching for the optimum mooring line composition in an automatic mode. Basically, the paper`s main goal is to introduce some methods to find the lowest cost solution for the mooring system in a short time. All of these methods were computationally implemented creating the intelligent system named PROANC, which deals with the semi-submersible mooring design in a quasi-static and deterministic approach. It should be noted that the proposed system exerts a strong appeal as a design tool for feasibility studies of a given oil field and its quasi-static results can be directly applied to a mooring program capable of performing dynamic analysis. Finally some simulations are executed for different water depths and its final results, including the expended time to run, are presented in order to prove the PROANC system wide potential as a design tool.

  16. Autonomous and rapid deployment of a compact taut-wire mooring

    The deployment time of a taut-wire mooring is reduced to the time any transportation/hoisting device needs to put a payload at the sea surface. This is a matter of minutes rather than hours needed for deployment of long deep-ocean moorings in the regular way. It is achieved by extending the basic function of mooring parts to temporarily form a Launcher for Oceanographic Equipment and Instruments (LOEI). Full preparation of the mooring is done onshore where the instruments are prepared and programmed, and spooled onto the top-buoy together with the line. At sea, no other gear is required than a device that is able to lift a load of, say, 2000 kg, even for long deep-ocean moorings. The compact mooring method realizes considerable budget savings through deployments from non-research vessels and airborne transportation-deployment. Limitations lay in size and weight of the oceanographic instruments. We present a test-design shaped as a barbell and loaded with 940 m line and 3 current meters. Unfurling speed was maximally 2.3 m s -1 and the descent speed amounted 1.2 m s -1 until landing on the seabed. These speeds are comparable to those acquired during a conventional free-falling mooring deployment.

  17. Load transfer with the Austin Moore cementless hip prosthesis.

    PubMed

    Keaveny, T M; Bartel, D L

    1993-03-01

    More than 1,300 Austin Moore hemiarthroplasties have been reviewed in the literature, with no reports of fracture of the stem. Many patients with these hip implants had good function. The lack of stem fractures in patients with good functions has not been explained and contrasts with stem fractures that have occurred in patients with cemented prostheses of other designs during the same time. We used three-dimensional finite-element analysis and free-body diagrams to explain the lack of fractures for this device by a description of the probable load-transfer mechanisms between the prosthesis and the bone. Results from our finite-element analysis indicate that, with good calcar-collar support, the stresses in the stem are small because the stem portion of the prosthesis and the bone are uncoupled and, consequently, do not share the resultant bending moment of the head and abductor forces. If the stem is coupled to the bone so that the resultant bending moment is shared, high stresses in the stem are predicted; such stresses are inconsistent with the complete absence of fractures of these prostheses. The results of the finite-element analysis further showed that loss of calcar-collar support with proximal fixation through the fenestrations resulted in high stresses in the stem and stress shielding of the proximal medial cortex. The uncoupled prosthesis also may be modeled with a free-body diagram as a three-force member loaded at the head, stem tip, and in the proximal region. With this model, it can be shown that the reaction force of the stem tip, and thus the peak bending stress in the stem, increases as calcar-collar support is decreased. If there is no calcar-collar support, proximal support must be provided by some combination of integration of bone in the fenestrations and wedging due to the lateral-medial taper of the device. Stresses in the stem are largest when there is no wedging, but high stresses develop in the cancellous bone in the fenestrations. When

    The Bermuda Testbed Mooring (BTM) program provides the oceanographic community with a deep-water platform for testing new instrumentation. Scientific studies also utilize data collected from the BTM, particularly in conjunction with the U.S. JGOFS Bermuda Atlantic Time-series Study (BATS) program. Additionally, the BTM has been used for groundtruthing of satellite ocean color imager (SeaWiFS) data. The mooring is located about 80 km southeast of Bermuda. Surface instruments have collected meteorological and spectral radiometric data from the buoy tower and measurements at depth have included: currents, temperature, bio-optical, chemical, and acoustical variables. The BTM captures a broad dynamic range of oceanic variability (minutes to years). Key results include: 1. Data obtained during passages of cold-core eddies have been used to estimate the role of such features on new production and carbon flux to the deep ocean. One of the observed features contained the greatest values of chlorophyll observed during the decade of observations at the site (based on BATS historical data base). The measurements provide high frequency, long-term data, which can be used for a) detailed studies of a variety of physical, chemical, bio-optical, and ecological processes on time scales from minutes to years, b) contextual information for many other observations made near the BTM/BATS sites, c) evaluation of undersampling/aliasing effects, and d) developing/testing models. 2. The dynamics of the upper ocean have been observed during transient re-stratification events and during passages of hurricanes and other intense storms. These observations are unique and the subject of ongoing modeling efforts. 3. BTM papers have provided new insights concerning bio-optical variability on short (minutes to day) time scales and have proven valuable for ocean color satellite groundtruthing. 4. During the BTM project, several new sensors and systems have been tested by U.S. and international groups

    Mooring systems are the most effective method for making sustained time series observations in the oceans. Generally there are two types of ocean mooring systems: surface and subsurface. Subsurface mooring system is less likely to be damaged after deployment than surface system. However, subsurface system usually needs to be retrieved from the ocean for data recovery. This paper describes the design and implementation of a new low-cost subsurface mooring system for efficient data recovery: Timed Communication Buoy System (TCBS). TCBS is usually integrated in the main float and the designated data is downloaded from the control system. After data retrieval, TCBS will separate from main float, rise up to the sea surface, and transmit data by satellite communication.

  1. MOORE: A prototype expert system for diagnosing spacecraft problems

    NASA Technical Reports Server (NTRS)

    Howlin, Katherine; Weissert, Jerry; Krantz, Kerry

    1988-01-01

    MOORE is a rule-based, prototype expert system that assists in diagnosing operational Tracking and Data Relay Satellite (TDRS) problems. It is intended to assist spacecraft engineers at the TDRS ground terminal in trouble shooting problems that are not readily solved with routine procedures, and without expert counsel. An additional goal of the prototype system is to develop in-house expert system and knowledge engineering skills. The prototype system diagnoses antenna pointing and earth pointing problems that may occur within the TDRS Attitude Control System (ACS). Plans include expansion to fault isolation of problems in the most critical subsystems of the TDRS spacecraft. Long term benefits are anticipated with use of an expert system during future TDRS programs with increased mission support time, reduced problem solving time, and retained expert knowledge and experience. Phase 2 of the project is intended to provide NASA the necessary expertise and capability to define requirements, evaluate proposals, and monitor the development progress of a highly competent expert system for NASA's Tracking Data Relay Satellite. Phase 2 also envisions addressing two unexplored applications for expert systems, spacecraft integration and tests (I and T) and support to launch activities. The concept, goals, domain, tools, knowledge acquisition, developmental approach, and design of the expert system. It will explain how NASA obtained the knowledge and capability to develop the system in-house without assistance from outside consultants. Future plans will also be presented.

    2013-06-01

    A comparison experiment has been taken in the Kiaochow Bay between a newly designed mooring turbulence observation instrument (MTOI) and microstructure profiler MSS60 made by Sea & Sun. The whole observing system is based on a submerged buoy, in which the turbulence observation instrument is embedded, with a streamline-shape floating body, which is made of buoyancy material of glass microsphere. For the movement of seawater and the cable shaking strongly anytime influence the behaviors of the floating body, the accelerate sensors are used for the vibration measurement in the instrument together with the shear probe sensor. Both the vibration data and the shear data are acquired by the instrument at the same time. During data processing, the vibration signals can be removed and leave the shear data which we really need. In order to prove the reliability of the new turbulence instrument MTOI, a comparison experiment was designed. The measuring conditions are the same both in time and space. By this way, the two groups of data are comparable. In this paper, the conclusion gives a good similarity of 0.93 for the two groups of shear data in dissipation rate. The processing of the data acquired by MTOI is based on the cross-spectrum analysis, and the dissipation rate of it matches the Nasmyth spectrum well.

  3. Study on global performances and mooring-induced damping of a semi-submersible

    The harsh environmental conditions bring strong nonlinearities to the hydrodynamic performances of the offshore floating platforms, which challenge the reliable prediction of the platform coupled with the mooring system. The present study investigates a typical semi-submersible under both the operational and the survival conditions through numerical and experimental methods. The motion responses, the mooring line tensions, and the wave loads on the longitudinal mid-section are investigated by both the fully non-linearly coupled numerical simulation and the physical experiment. Particularly, in the physical model test, the wave loads distributed on the semi-submersible's mid-section were measured by dividing the model into two parts, namely the port and the starboard parts, which were rigidly connected by three six-component force transducers. It is concluded that both the numerical and physical model can have good prediction of the semi-submersible's global responses. In addition, an improved numerical approach is proposed for the estimation of the mooring-induced damping, and is validated by both the experimental and the published results. The characteristics of the mooring-induced damping are further summarized in various sea states, including the operational and the survival environments. In order to obtain the better prediction of the system response in deep water, the mooring-induced damping of the truncated mooring lines applied in the physical experiment are compensated by comparing with those in full length. Furthermore, the upstream taut and the downstream slack mooring lines are classified and investigated to obtain the different mooring line damping performances in the comparative study.

  4. The ARGOS contribution to the successful dredging of a deep moored current meter

    Current meters moored at 1200 m from a seabed 4600 m deep in the Indian Ocean were recovered using the ARGOS system after failure of the explosive anchor-release bolts prevented recovery using acoustic methods. The position of each mooring was known to within 0.25 nautical miles, so the ARGOS system was used to position the recovery ships to within 100 m of the targets.

    Two profiling subsurface moorings were deployed as part of the CLIvar MOde Water Dynamics Experiment (CLIMODE) to study the formation and evolution of Eighteen Degree Water (EDW) from November 2006 to November 2007. Both moorings were deployed south of the Gulf Stream in the EDW outcrop region, the northwestern part of the subtropical gyre of the North Atlantic. The two moorings captured the seasonal evolution of EDW characterized by gradual mixed layer deepening and wintertime outcrop, rapid restratification from May to June and slower dissipation during the rest of the year. Superimposed on this seasonal cycle, the moored records are characterized by high frequency passing of eddies with a characteristic time scale of ˜10 days, i.e. it took about 10 days for eddies to pass the mooring sites. The net impact of these eddy fluxes is evaluated by analyzing one-dimensional heat and salt budgets of the upper ocean at the moorings and comparing them to the local air-sea fluxes. It is shown that oceanic lateral fluxes converge heat and salt into the formation region during winter thus offsetting the heat loss to the atmosphere and influencing the formation of EDW. A comparison with results from a one-dimensional model shows that without the lateral fluxes EDW would outcrop earlier and it would be colder and fresher. The warm, salty waters transported into the region originate from the Gulf Stream and this suggests that frontal processes likely play a fundamental role in EDW formation and its evolution.

    Analytical expressions of the necessary and sufficient conditions for stability of mooring systems representing bifurcation boundaries, and expressions defining the morphogeneses occurring across boundaries are presented. These expressions provide means for evaluating the stability of a mooring system around an equilibrium position and constructing catastrophe sets in any parametric design space. These expressions allow the designer to select appropriate values for the mooring parameters without resorting to trial and error. A number of realistic applications are provided for barge and tanker mooring systems which exhibit qualitatively different nonlinear dynamics. The mathematical model consists of the nonlinear, third order maneuvering equations of the horizontal plane slow motion dynamics of a vessel moored to one or more terminals. Mooring lines are modeled by synthetic nylon ropes, chains, or steel cables. External excitation consists of time independent current, wind, and mean wave drift forces. The analytical expressions presented in this paper apply to nylon ropes and current excitation. Expressions for other combinations of lines and excitation can be derived.

    Regolith is disaggregated, transportable material above bedrock created by physical processes such as fracture generation, frost cracking, tree throw, and animal burrowing and chemical processes such as dissolution and mineral transformation. Models typically parameterize the rate of regolith generation as a function of its thickness, without specifying the physical and chemical processes involved. This study examines a non-glaciated, granitic hillslope on Bodmin Moor, southwest England, UK, to identify processes creating regolith. The site has a temperate climate with relatively high mean annual temperature (MAT,~10°C) and rainfall (1381- 2580mm). We dug five soil pits ~80cm deep along a 120 m transect to examine the saprolite-regolith interface and extract solid phase and soil pore water samples. We find no evidence of physical processes such as frost cracking or bioturbation creating regolith. The site is treeless with vegetation dominated by grass. Although the site experiences ground frost and has sufficient water content to support frost cracking, a model of freezing front penetration indicates that the saprolite-regolith boundary does not fall within the frost cracking window of -3 to -10°C. A decrease in MAT of ~3°C would lower the depth of frost penetration to the current saprolite-regolith boundary (80cm). We speculate that frost cracking may have operated during the periglacial conditions of the Quaternary and would have pre-conditioned the bedrock for chemical processes currently operating. We use soil pore water and solid phase chemistry to determine the chemical processes at work. Pore water concentrations of K (4.5 mg/L), Na (14.2 mg/L), SO42- (24.9 mg/L), Mg (1.7 mg/L), and Ca (1.7 mg/L) are highest in O-horizons and decrease as a function of distance from the surface, indicating that biological processes have a strong effect on geochemical cycling in the upper part of the soil. Soil water at greater depths within the regolith are likely under

    The Ocean Thermal Energy Conversion (OTEC) Moored Pipe/Mobile Platform (MP-Squared) Design Study was carried out to investigate an innovative approach to the moored floating OTEC plant. In the past, a number of concepts have been examined by NOAA for floating OTEC plants. These concepts have considered various configurations for platforms, cold water pipes and mooring systems. In most cases the cold water pipe (CWP) was permanently attached to the platform and the platform was permanently moored on station. Even though CWP concepts incorporating articulated joints or flexible pipes were used, the CWP stresses induced by platform motion were frequently excessive and beyond the design limits of the CWP. This was especially true in the survival (100-year storm) case. It may be feasible that the concept of a permanently moored CWP attached through a flexible transition CWP to the platform could reduce the degree of technical risk by de-coupling the CWP from the motions of the platform. In addition, if the platform is capable of disconnecting from the CWP during survival conditions, even less technical risk may be inherent in the OTEC system. The MP-Squared Design Study was an engineering evaluation of the concepts described above. The effort has been carried through to the conceptual design level, and culminated in model tests in an experimental wave basin.

  9. Building oceanographic moorings in a non-lab introductory ocean science course

    2014-12-01

    A methodology for building low-cost ocean moorings in an introductory ocean sciences course, using HOBO temperature and light pendants, is presented. The moorings, which collect water temperature and light intensity data at high temporal frequency and at multiple depths, are relatively inexpensive, with a total cost of approximately 15 to 30 per student, depending on the configuration. Deployments of multiple months, or even longer, are possible, but in this presentation two ~3-week long deployments are described. Students in an Introduction to Oceanography course at Peninsula College in Port Angeles, Washington (USA) designed and constructed moorings for deployment in an enclosed harbor at depths of ~8 meters. The HOBO pendants integrated into the moorings were set to log observations at one hour intervals. After mooring recovery students downloaded data, which were both incorporated into class lessons where feasible, but were also utilized in a fully inquiry-based research paper. The exercise was often cited in students' evaluations as a highlight, and served to both teach and reinforce oceanographic concepts, introduce students to professional options within ocean science and engineering fields, and provide skills training (by requiring students to work in Excel for data manipulation, for example).

    Silicon's intersection with biology is a premise inherent in Moore's prediction. Distinct from biologically inspired molecular logic and storage devices (more Moore) are the integration of solid state electronic devices with the soft condensed state of the body (more than Moore). Developments in biomolecular recognition events per sq. cm parallel those of Moore's Law. However, challenges continue in the area of "More than Moore". Two grand challenge problems must be addressed—the biocompatibility of synthetic materials with the myriad of tissue types within the human body and the interfacing of solid state micro- and nano-electronic devices with the electronics of biological systems. Electroconductive hydrogels have been developed as soft, condensed, biomimetic but otherwise inherently electronically conductive materials to address the challenge of interfacing solid state devices with the electronics of the body, which is predominantly ionic. Nano-templated interfaces via the oriented immobilization of single walled carbon nanotubes (SWCNTs) onto metallic electrodes have engendered reagentless, direct electron transfer between biological redox enzymes and solid state electrodes. In addressing these challenges, metrology needs and opportunities are found in such widely diverse areas as single molecule counting and addressing, sustainable power requirements such as the development of implantable biofuel cells for the deployment of implantable biochips, and new manufacturing paradigms to address plura-biology needs on solid state devices.

    The dynamic responses of any floating platform are dependent on the mass, stiffness and damping characteristics of the body as well as mooring system. Therefore, it is very essential to study the effect of individual contributions to the system that can finally help to economise their cost. This paper focuses on the effect of mooring stiffness on the responses of a truss spar platform, obtained by different grouping of lines. The study is part of our present researches on mooring systems which include the effect of line pretension, diameter and azimuth angles. The platform is modelled as a rigid body with three degrees-of-freedom and its motions are analyzed in time-domain using the implicit Newmark Beta technique. The mooring lines restoring force-excursion relationship is evaluated using a quasi-static approach. It is observed that the mooring system with lines arranged in less number of groups exhibits better performance in terms of the restoring forces as well as mean position of platform. However, the dynamic motions of platform remain unaffected for different line groups.

    A thin layer of fresh water from summer monsoon rain and river runoff in the Bay of Bengal (BoB) has profound influence on air-sea interaction across the south Asian region, but the mechanisms that sustain the low-salinity layer are as yet unknown. Using the first long time series of high-frequency observations from a mooring in the north BoB and satellite salinity data, we show that fresh water from major rivers is transported by large-scale flow and eddies, and shallow salinity stratification persists from summer through the following winter. The moored observations show frequent 0.2-1.2 psu salinity jumps with time scales of 10 min to days, due to O(1-10) km submesoscale salinity fronts moving past the mooring. In winter, satellite sea surface temperature shows 10 km wide filaments of cool water, in line with moored data. Rapid salinity and temperature changes at the mooring are highly coherent, suggesting slumping of salinity-dominated fronts. Based on these observations, we propose that submesoscale fronts may be one of the important drivers for the persistent fresh layer in the north BoB.

    Lumped Mass method is a proven numerical approach to analyze the problems of mooring lines. The two-dimensional method was originally developed by Walton and Polachek (1959) for various conditions of frequency and amplitude. Nakajima et al (1982) carried out investigation on the dynamics of mooring lines. In this paper, the interaction of mooring line with the ocean bottom is highlighted and the resulted reduction in dynamic tension is discussed. The line is divided into finite number of lumped masses and linear springs without mass. The damping, associated with the interaction of vibrating chain with the sea bed which is considered to be elastic, is incorporated in the computations. In normal case some part of mooring line will be on the surface of sea floor. Modification to the lumped mass method is done in view of the changed external forces with the change of mode of velocity amplitude along the length of the chain embedded in the sea bottom media. The validation of the modified Lumped Mass method is confirmed by comparing the dynamics of chain on elastic foundation by N.C. Perkins (1990). The sea floor conditions can be found varied for different locations of anchoring and the properties of the sea bottom media influences energy dissipation when the mooring line is interacting with it. The dynamic behavior of chain will be different depending upon the change in sea bottom conditions.

    The Floating Production Systems (FPS) or the Floating, Storage and Offloading Systems (FPSO) have been applied to marginal oil fields or early production systems since late `70 in view of less capital and short delivery. There are two types of floating production systems: semi-submersible based spread mooring type and tanker-based single point mooring. This paper describes the analysis method, the technical development of optimization programs and the model experiments for the Single Point Mooring (SPM) systems for FPSO, which have been carried out as a joint research project by Japan National Oil Corporation, Akishima Laboratories Inc. and MODEC Inc. The detailed analysis program is developed based on the constraint matrix method in frequency and time domains and is capable of calculating the motions and constraint forces of SPM in wind, current and random waves. Outline of calculation method is presented.

    An essential step in many controller design approaches is computing the inverse of the plant. For a square plant, its inverse is stable if the plant is minimum phase (MP). Nevertheless, this conclusion does not hold for a non-square plant. In this paper, the pole feature of the Moore-Penrose pseudo-inverse of a non-square transfer function matrix is analysed. Instead of complicated advanced mathematical tools, only basic results of polynomial theory and the Binet-Cauchy theorem are used in the analysing procedure. The condition for testing the stability of the Moore-Penrose pseudo-inverse of an MP non-square transfer function matrix is given. This condition implies that the Moore-Penrose pseudo-inverse of a non-square transfer function matrix cannot be directly used as the optimal controller. Numerical examples are provided to illustrate the correctness of the condition.

    In this paper, the authors investigate the very large amplitude roll motions of the capsized MODU Ocean Ranger. They utilize the dynamical systems approach to analyze all possible motions for fixed vessel and environmental conditions. They include the effects of wind bias and an equivalent mooring system. As expected, they find the effects of wind bias to dramatically effect the system`s safe basin, a measure of the vessel`s resistance to capsizing. Somewhat surprisingly, they find the mooring system to have a limited effect on the roll due to its small size relative to the hydrostatic roll restoring moment.

    Floating facilities have been studied based on the static analysis of mooring cables over the past decades. To analyze the floating system of a spherical buoy moored by a cable with a higher accuracy than before, the dynamics of the cables are considered in the construction of the numerical modeling. The cable modeling is established based on a new element frame through which the hydrodynamic loads are expressed efficiently. The accuracy of the cable modeling is verified with an experiment that is conducted by a catenary chain moving in a water tank. In addition, the modeling of a spherical buoy is established with respect to a spherical coordinate in three dimensions, which can suffers the gravity, the variable buoyancy and Froude-Krylov loads. Finally, the numerical modeling for the system of a spherical buoy moored by a cable is established, and a virtual simulation is proceeded with the X- and Y-directional linear waves and the X-directional current. The comparison with the commercial simulation code ProteusDS indicates that the system is accurately analyzed by the numerical modeling. The tensions within the cable, the motions of the system, and the relationship between the motions and waves are illustrated according to the defined sea state. The dynamics of the cables should be considered in analyzing the floating system of a spherical buoy moored by a cable.

    2013-06-01

    Floating platform system has been extensively used in ocean exploitation, particularly for a tension-leg platform (TLP) system in deep water. Most of the TLPs are multi-mooring systems, where multi-joints are connected to the tension-legs so that the platform is not allowed to twist freely and may subject to enormous force induced by large incident waves in the weak-direction of the structure. This study aims to exploit a single moored offshore platform system that may attract less force and can be operated with less effort. In our analysis, in addition to mechanical properties of the tether, two important properties are also taken into consideration for the single mooring tether with expanded cross sectional dimension and utilization of stronger material, namely, the sag-extensibility and the flexural rigidity. Finally, the dynamic structural behavior produced by the mechanical effects on the new system is investigated and compared with that of traditional design while the wave-structure interactions of large body are also accounted for. Our study finds that the neglect of sag-extensibility or the flexural rigidity of large, strong mooring cable may result in a conservative but not necessarily safe design.

    A fundamental aspect of observing, describing, understanding and modeling the global climate and particularly the Maritime Continent, is a better knowledge of the fluxes of momentum, heat and freshwater in the ocean. The Indonesian seas are the only major low-latitude connection in the global oceans. This connection permits the transfer of Pacific waters into the Indian Ocean, known as the Indonesian Throughflow. The interaction of the Pacific and Indian basins and their modes of variability (El Niño-Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD)), both through atmospheric teleconnections and the ocean link via the Indonesian Throughflow, is now being hotly pursued in the research community. We will present some initial findings from the 3-year time series (2011-2014) of the Timor Passage and Ombai Strait moorings. This mooring array is a component of the Australian Integrated Marine Observing System (IMOS), and builds on the earlier results of the INSTANT (2003-2006) observational program. The moorings comprise of velocity, temperature and salinity instruments. Observations from these moorings provide the required spatial and temporal coverage to understand ocean dynamics, the ocean's role in climate variability and change, investigate forcing of the atmosphere and ocean and assess the realism of data-assimilative ocean models and coupled ocean-atmosphere models.

  13. Use of multi-disciplinary mooring data to extend intermittent OA observations from ship surveys

    Ship surveys along the US West Coast have provided valuable insight into the conditions and changes in the water column that affect the ocean acidification state. Examples are the decades of CalCOFI sampling off southern California, and the West Coast ship survey published in Feely et al 2008. What is lacking in these observations is a description of the temporal variability of the conditions observed, and of the processes at work that lead to observed conditions or changes. Multi-disciplinary moorings are ideally suited for adding this dimension to the available observations which is critical for an understanding of the OA mechanisms. One example is the occurrence of corrosive water near the seafloor on the continental shelf, which was found in the Feely et al survey. Time series data from a mooring off Del Mar, California, with oxygen and pH sensors near the bottom in 100m depth show the frequency and intensity of corrosive and hypoxic conditions there, and how they relate to physical processes (cross-shelf and along-shelf flow), biological conditions, and climate processes (here La Nina). In the upwelling and open-ocean regimes off Pt. Conception two moorings (CCE1, CCE2) have been collecting data since early 2009 and 2010, respectively, co-located with CalCOFI stations and CCE LTER cardinal sites for ship observations. A glider also routinely passes by these moorings (along CalCOFI line 80). The moorings carry physical, oxygen, pH, pCO2, nutrient, and ecosystem sensors (chlorophyll fluorescence, water column irradiance absorption, acoustic backscatter) and telemeter most data in real-time. The mooring time series show the variability of OA parameters on daily, weekly, seasonal, and interannual time scales, and in the context of the spatial and historical sampling from ships. The multi-disciplinary sensor suite allows to study the forcing of the OA variability on those various time scales, and the impact on the ecosystem. Combined with the spatial information

    2000-08-08

    The main conclusions from the work carried out under this contract are: An ordinary seafarer can learn by training on a simulator, to moor large tanker vessels to the Hydrostatic Mooring, safely and quickly, in all weather conditions up to storms generating waves with a significant wave height of 8 m. Complete conceptual design of the Hydrostatic Mooring buoy was carried out which proved that the buoy could be constructed entirely from commercially available standard components and materials. The design is robust, and damage resistant. The mooring tests had a 100% success rate from the point of view of the buoy being securely attached and moored to the vessel following every mooring attempt. The tests had an 80% success rate from the point of view of the buoy being adequately centered such that petroleum transfer equipment on the vessel could be attached to the corresponding equipment on the buoy. The results given in Table 3-2 of the mooring tests show a consistently improving performance from test to test by the Captain that performed the mooring operations. This is not surprising, in view of the fact that the Captain had only three days of training on the simulator prior to conducting the tests, that the maneuvering required is non-standard, and the test program itself lasted four days. One conclusion of the test performance is that the Captain was not fully trained at the initiation of the test. It may therefore be concluded that a thoroughly trained navigator would probably be able to make the mooring such that the fluid transfer equipment can be connected with reliability in excess of 90%. Considering that the typical standard buoy has enough power aboard to make eight mooring attempts, this implies that the probability that the mooring attempt should fail because of the inability to connect the fluid transfer equipment is of the order of 10{sup {minus}8}. It may therefore be concluded that the mooring operation between a Hydrostatic Mooring and a large

    Nichol, Tyler

    The development of a numerical model simulating the dynamic response of compliant-moored submerged systems to non-uniform fluid flow is presented. The model is meant to serve as a computational tool with applications to compliant-moored marine energy converters by time-domain representation of the mooring dynamics. The scope of the initial code is restricted to full-submerged moored tidal turbines, though the model can be readily expanded to analyze wave energy converters as well. The system is modeled in a Lagrangian frame treating tidal turbines and structural elements as rigid bodies. Mooring lines are modeled as a series of discrete elastic segments, with parameters and force contributions lumped to point-mass nodes joining each segment. Full-range of motion is achieved using the alpha-beta-gamma Euler Angle method. The governing equations of motion of the system are derived computationally through implementation of Lagrange's Equation of Motion. The techniques employed to develop the symbolic expressions for the total kinetic, potential, and damping energies of the system and the forces acting on each element of the system are discussed. The system of differential equations obtained from evaluation of Lagrange's Equation with the developed symbolic expressions is solved numerically using a built-in MATLAB ordinary differential equation solver called ODE15i.m with the user defined initial condition of the system. Several validation tests are presented and their results discussed. Finally, an explanation of future plans for development of the model and application to existing tidal energy systems are presented.

    parts. The field of optoelectronics and photonics has been benefiting from the ability to synthesize semiconducting nanowires and quantum dots. Advances in light-emitting diodes, photodetectors, nanolasers, solar cells, and field emission devices have been abundantly reported in the journal. The future of these devices depends on our ability to control the size, orientation and properties of one- and zero-dimensional materials. The forecast for electronics and photonics has vastly underestimated developments, with predictions such as 'future computers will weigh no less than 1.5 tons'. Over the past twenty years, the number of transistors on a chip has risen from just 1 million to 2 billion, and is still increasing. Now the biggest question is: what will take over from Moore's law in about a decade? This question has been driving the research agenda in electronics across the industrial and academic world. The first answer appears to be integrating other functional components with logic and memory such as miniature camera modules, GPS, accelerometers, biometric identification, health monitoring systems, etc. Such integration is actively being pursued by industry. In contrast, a lot of new research is still driven by material innovations, for example, carbon nanotube based electronics. Rudimentary devices and circuits using SWCNTs have been demonstrated to outperform silicon devices of comparable size. However, controlling the chirality and diameter of SWCNTs is still a problem, as is the manufacture of 300-400 mm wafers with over 5-10 billion transistors, and all of this assumes that continuing on the path of CMOS but using a different material is the right approach in the first place. In the meantime, silicon and germanium in the form of nanowires may make their way into electronics. Then there is molecular electronics where conducting organic molecules could now become the heart of electronic components, although the precision and controllability of electrical contact

    Assessing the fatigue life of mooring systems is important for deep water structures. In this paper, a comprehensive fatigue analysis is conducted on the mooring lines applied in a semi-submersible platform with special focus on the low frequency (LF) fatigue damage. Several influential factors, including water depth, wave spectral parameters, and riser system, are considered. Numerical simulation of a semi-submersible platform with the mooring/riser system is executed under different conditions, and the fatigue damage of mooring lines is assessed by using the time domain analysis method as a benchmark. The effects of these factors on the mooring line tension and the fatigue damage are investigated and discussed in detail. Research results indicate that the LF fatigue damage only accounts for a very small portion of the total damage, although the LF components dominate the global motion response and the mooring line tension of the semi-submersible platform. However, it is demonstrated that the LF fatigue damage is clearly affected by the influential factors. The increase in water depth and spectral peak periods, and the existence of risers can weaken the contribution of the LF components to the mooring line fatigue damage, while the fatigue damage due to the LF components increases with the increase of significant wave height.

    In 1965 Gordon Moore wrote an article claiming that integrated circuit density would scale exponentially. His prediction has remained valid for more than four decades. Integrated circuits have changed all aspects of everyday life. They are also the 'heart and soul' of modern systems for defense, national infrastructure, and intelligence applications. The United States government needs an assured and trusted microelectronics supply for military systems. However, migration of microelectronics design and manufacturing from the United States to other countries in recent years has placed the supply of trusted microelectronics in jeopardy. Prevailing wisdom dictates that it is necessary to use microelectronics fabricated in a state-of-the-art technology for highest performance and military system superiority. Close examination of silicon microelectronics technology evolution and Moore's Law reveals that this prevailing wisdom is not necessarily true. This presents the US government the possibility of a totally new approach to acquire trusted microelectronics.

    Non-rigid registration of MR images to a common reference image results in deformation fields, from which anatomical differences can be statistically assessed, within and between populations. Without further assumptions, nonparametric tests are required and currently the analysis of deformation fields is performed by permutation tests. For deformation fields, often the vector magnitude is chosen as test statistic, resulting in a loss of information. In this paper, we consider the three dimensional Moore-Rayleigh test as an alternative for permutation tests. This nonparametric test offers two novel features: first, it incorporates both the directions and magnitude of the deformation vectors. Second, as its distribution function is available in closed form, this test statistic can be used in a clinical setting. Using synthetic data that represents variations as commonly encountered in clinical data, we show that the Moore-Rayleigh test outperforms the classical permutation test. PMID:19694294

    A turret-moored, floating-type early production and testing system (EPTS) can weather the severe conditions for marginal field exploitation of East Asian offshore oil fields. These vessels are an alternative to permanent facilities such as conventional jackets that often are uneconomical for marginal fields and deepwater, harsh environments. The required production system must withstand the severe weather conditions of a typhoon. Weather downtime and the associated motion performance, weather-vaning capabilities, and mooring system requirements are main considerations in designing EPTSs for these environments. An example of the EPTS concept is the Petrojarl 1, which operates in the North Sea and was built by NKK Corp. The results of 6 years` experience with the Petrojarl 1 have proven that such vessels can operate even in the harsh environment of the North Sea. The study, summarized in this article, verified that satisfactory operational efficiency can be achieved in environments where typhoons exits.

    An approach to collect high frequency turbulence data at a tidal energy site is evaluated in a short demonstration deployment. The Tidal Turbulence Mooring improves upon recent bottom-mounted approaches by suspending Acoustic Doppler Velocimeters (ADVs) at mid-water depths (which are relevant to tidal turbines). The ADV turbulence data are superior to Acoustic Doppler Current Profiler (ADCP) data, but are subject to motion contamination when suspended on a mooring in strong currents. In this demonstration, passive stabilization is shown to be sufficient for acquiring bulk statistics of the turbulence, without motion correction. With motion correction (post-processing), data quality is further improved; the relative merits of direct and spectral motion correction are investigated.

    Low temperatures generally limit rates of chemical weathering, and hence might be expected to limit development and evolution of mobile regolith in cold climates. Chemical and physical processes operate to release material from bedrock into the mobile regolith. Rock is weakened by chemical weathering, while physical breakdown produces particles susceptible to transport. We examine two hillslopes mantled with mobile regolith in granitic terrains that formed in cold climates where the rates of chemical processes are expected to be low, while at least some physical processes are expected to be enhanced. These end-member environments provide insight into mobile regolith development. Our study sites are gentle parabolic hillslopes at Osborn Mtn, WY, USA (elevation: 3600 m, MAT: -5°C) and Bodmin Moor, Cornwall, UK (elevation: 370 m, MAT: 9°C) developed on granitic bedrock. Neither site experienced direct glaciation during the LGM, but both were in periglacial zones. At present, the sites are populated by neither trees nor burrowing mammals. Biotite, which might spawn rock breakdown by hydration/oxidation cracking, is rare. Although there is evidence that trees have grown in Bodmin Moor in the past, frost cracking rather than tree throw has likely been the dominant mechanism releasing intact material into the mobile soil column at both field sites over the Quaternary. Present day ground surface temperatures at Osborn Mtn are below 0°C for ~9 months of the year, as measured by temperature sensors, leaving only 3 months for chemical processes to operate. During winter, temperatures are cold enough for frost cracking to occur down to significant depths. In contrast, we calculate from a numerical model of the annual thermal cycle that the immediate sub-surface of the Bodmin Moor hillslope is not currently cold enough for frost cracking at any time of the year, meaning that chemical processes can operate continuously. However, given temperature drops of order 5-10°C during

    Carbon isotope and lignin phenol compositions were investigated to assess particulate organic carbon (POC) in a small river from the Bekanbeushi Moor in the eastern part of Hokkaido, Japan. Suspended solids were collected 5 times at a fixed station during July 2004-April 2008. The δ 13C values of the riverine POC are almost constant: -29.1‰ to -28.7‰. In contrast, the POC shows wide variations in Δ 14C values from -103‰ during the snowmelt event to +9 ± 16‰ during summer and winter. The cinnamyl over vanillyl phenol ( C/ V) ratios indicate a predominance of nonwoody materials and no seasonal variation, suggesting that the wetland river transports older POC from the riverbank during the spring snowmelt. The river also transports newly produced and stored soil organic matter as riverine POC from the low moor in times of low flow conditions.

    The application of formal methods to the analysis of computing systems promises to provide higher and higher levels of assurance as the sophistication of our tools and techniques increases. Improvements in tools and techniques come about as we pit the current state of the art against new and challenging problems. A promising area for the application of formal methods is in real-time and distributed computing. Some of the algorithms in this area are both subtle and important. In response to this challenge and as part of an ongoing attempt to verify an implementation of the Interactive Convergence Clock Synchronization Algorithm (ICCSA), we decided to undertake a proof of the correctness of the algorithm using the Boyer-Moore theorem prover. This paper describes our approach to proving the ICCSA using the Boyer-Moore prover.

    For water depths greater than 60m floating wind turbines will become the most economical option for generating offshore wind energy. Tension mooring stabilised units are one type of platform being considered by the offshore wind energy industry. The complex mooring arrangement used by this type of platform means that the dynamics are greatly effected by offsets in the positioning of the anchors. This paper examines the issue of tendon anchor position tolerances. The dynamic effects of three positional tolerances are analysed in survival state using the time domain FASTLink. The severe impact of worst case anchor positional offsets on platform and turbine survivability is shown. The worst anchor misposition combinations are highlighted and should be strongly avoided. Novel methods to mitigate this issue are presented.

    Monitoring seawater temperature is important to understanding evolving ocean processes. To monitor internal waves or ocean mixing, a large number of temperature loggers are typically mounted on subsurface mooring systems to obtain high-resolution temperature data at different water depths. In this study, we redesigned and evaluated a compact, low-cost, self-contained, high-resolution and high-accuracy ocean temperature logger, TC-1121. The newly designed TC-1121 loggers are smaller, more robust, and their sampling intervals can be automatically changed by indicated events. They have been widely used in many mooring systems to study internal wave and ocean mixing. The logger’s fundamental design, noise analysis, calibration, drift test, and a long-term sea trial are discussed in this paper.

    Dr. Paul Moore pioneered the use of high-speed cinematography for observation of normal and abnormal vocal fold vibrations during phonation. His analysis of the glottal area waveform, opening and closing speed index, and open quotient from the high-speed films were labor intensive but relevant today. With advances in digital image capture and automated image extraction techniques, stroboscopy and high-speed images of vocal fold vibration may be analyzed with objective measures. Digital high-speed image capture in color is now clinically practical at high resolution. Digital kymography now allows analysis of the vibratory waveform from each vocal fold. Serial capture and comparison can document changes in vibratory function with treatment. Quantification of vocal fold vibration using such techniques is now practical. This is a review of vocal fold vibration capture and analysis techniques since Dr. Moore. PMID:24094798

    In June 2007 tropical Cyclone Gonu passed directly over an ocean observing system consisting of four, deep autonomous mooring stations along the 3000 m isobath in the northern Arabian Sea. Gonu was the largest cyclone known to have occurred in the Arabian Sea or to strike the Arabian Peninsula. The mooring system was designed by Lighthouse R & D Enterprises, Inc. and installed in cooperation with the Oman Ministry of Agriculture and Fisheries Wealth. The instruments on the moorings continuously recorded water velocities, temperature, conductivity, pressure, dissolved oxygen and turbidity at multiple depths and at hourly intervals during the storm. Near-inertial oscillations at all moorings from thermocline to seafloor are coincident with the arrival of Gonu. Sub-inertial oscillations with periods of 2-10 days are recorded at the post-storm relaxation stage of Gonu, primarily in the thermocline. These oscillations consist of warm, saline water masses, likely originating from the Persian Gulf. Prominent 12.7-day sub-inertial waves, measured at a station ~300 km offshore, are bottom-intensified and have characteristics of baroclinic, topographically-trapped waves. Theoretical results from a topographically-trapped wave model are in a good agreement with the observed 12.7-day waves. The wavelength of the 12.7-day waves is about 590 km calculated from the dispersion relationship. Further analysis suggests that a resonant standing wave is responsible for trapping the 12.7-day wave energy inside the Sea of Oman basin. The observational results reported here are the first measurements of deepwater responses to a tropical cyclone in the Sea of Oman/Arabian Sea. Our study demonstrates the utility of sustained monitoring for studying the impact of extreme weather events on the ocean.

    Optical measurements from an untended mooring provide high-frequency observations of in-water optical properties and permit the estimation of important biological parameters continuously as a function of time. A 9-month time series, composed of three separate deployments, of optical data from the BIOWATT 1987 deep-sea mooring located in the oligotrophic waters of the Sargasso Sea at 34 deg N, 70 deg W are presented. These data have been tested using several bio-optical models for the purpose of providing a continuous estimate of phytoplankton productivity. The data are discussed in the context of contemporaneous shipboard observations and for future ocean color satellite observations. We present a continuous estimation of phytoplankton productivity for the 9-month time series. Results from the first 70-day deployment are emphasized to demonstrate the utility of optical observations as proxy measures of biological parameters, to present preliminary analysis, and to compare our bio-optical observations with concurrent physical observations. The bio-optical features show variation in response to physical forcings including diel variations of incident solar irradiance, episodic changes corresponding to wind forcing, variability caused by advective mesoscale eddy events in the vicinity of the mooring, and seasonal variability corresponding to changes in solar radiation, shoaling of the mixed layer depth, and succession of phytoplankton populations.

    Indigo naturalis is effective in treating nail psoriasis coexisting with microorganism infections. This study examines the antimicrobial effects of indigo naturalis prepared from Strobilanthes formosanus Moore. Eight bacterial and seven fungal strains were assayed using the agar diffusion method to examine the effects of indigo naturalis and its bioactive compounds. The bioactive compounds of indigo naturalis were purified sequentially using GFC, TLC, and HPLC. Their structures were identified using mass spectrometry and NMR spectroscopy. UPLC-MS/MS was applied to compare the metabolome profiles of indigo naturalis ethyl-acetate (EA) extract and its source plant, Strobilanthes formosanus Moore. The results of in vitro antimicrobial assays showed that indigo naturalis EA-extract significantly (≥1 mg/disc) inhibits Gram-positive bacteria (Staphylococcus aureus, S. epidermis and methicillin-resistant S. aureus (MRSA)) and mildly inhibits non-dermatophytic onychomycosis pathogens (Aspergillus fumigates and Candida albicans), but has little effect on dermatophyes. Isatin and tryptanthrin were identified as the bioactive compounds of indigo naturalis using S. aureus and S. epidermis as the bioassay model. Both bioactive ingredients had no effect on all tested fungi. In summary, indigo naturalis prepared from Strobilanthes formosanus Moore exhibits antimicrobial effects on Staphylococcus and non-dermatophytic onychomycosis pathogens. Tryptanthrin and isatin may be its major bioactive ingredients against Staphylococcus and the inhibitory effect on MRSA may be due to other unidentified ingredients. PMID:24284490

    Freak wave is the common wave which has significant wave height and irregular wave shape, and it is easy to damage offshore structure extremely. The FPSOs (Floating Production Storage and Offloading) suffer from the environment loads, including the freak wave. The freak waves were generated based on the improved phase modulation model, and the coupling model of FPSO-SPM (Single Point Mooring) was established by considering internal-turret FPSO and its mooring system. The dynamic response characteristics of both FPSO and SPM affected by the freak wave were analyzed in the time domain. According to the results, the freak waves generated by original phase modulation model mainly affect the 2nd-order wave loads. However, the freak waves which are generated by random frequencies phase modulation model affect both 1st-order and 2nd-order wave loads on FPSO. What is more, compared with the irregular waves, the dynamic responses of mooring system are larger in the freak waves, but its amplitude lags behind the peak of the freak wave.

    The string searching task can be classified as a classic information processing task. Users either encounter the solution of this task while working with text processors or browsers, employing standard built-in tools, or this task is solved unseen by the users, while they are working with various computer programmes. Nowadays there are many algorithms for solving the string searching problem. The main criterion of these algorithms’ effectiveness is searching speed. The larger the shift of the pattern relative to the string in case of pattern and string characters’ mismatch is, the higher is the algorithm running speed. This article offers a combined algorithm, which has been developed on the basis of well-known Knuth-Morris-Pratt and Boyer-Moore string searching algorithms. These algorithms are based on two different basic principles of pattern matching. Knuth-Morris-Pratt algorithm is based upon forward pattern matching and Boyer-Moore is based upon backward pattern matching. Having united these two algorithms, the combined algorithm allows acquiring the larger shift in case of pattern and string characters’ mismatch. The article provides an example, which illustrates the results of Boyer-Moore and Knuth-Morris- Pratt algorithms and combined algorithm’s work and shows advantage of the latter in solving string searching problem.

    B. F. Skinner founded both radical behaviorism and behavior analysis. His founding innovations included: a versatile preparation for studying behavior; explicating the generic nature of stimulus and response; a pragmatic criterion for defining behavioral units; response rate as a datum; the concept of stimulus control; the concept of verbal behavior; and explicating the explanatory power of contingencies. Besides these achievements, however, Skinner also made some mistakes. Subsequent developments in radical behaviorist thought have attempted to remedy these mistakes. Moore's book presents a “party line” version of radical behaviorism. It focuses narrowly on a few of Skinner's concepts (mostly mentalism and verbal behavior) and contains no criticism of his mistakes. In fact, Moore adds a few mistakes of his own manufacture; for example, he insists that the mental realm does not exist—an unprovable and distracting assertion. The book's portrayal of behavior analysis would have been current around 1960; it mentions almost none of the developments since then. It also includes almost no developments in radical behaviorism since Skinner. Moore's book would give an unwary reader a highly distorted picture of contemporary behavior analysis and radical behaviorism.

    2014-03-01

    This review presents an analysis of literature data and original studies by the authors aimed at revealing the factors inhibiting the destruction of high-moor (oligotrophic) peat. Each of the ecological factors that prevent the decomposition of the high-moor peat by different groups of microorganisms is considered. The acid reaction, low temperatures, and lack of nutrients were found not to be the primary factors inhibiting the destruction of the peat. The limited content of oxygen in the peatbogs leads to a drastic decrease in the number of mycelial microorganisms and a reduction of the activity of hydrolytic and oxidizing enzymes. The main factor inhibiting the decomposition of sphagnum is its mechanical and chemical stability, since animals crushing sphagnum are absent in the soil, and this moss has polysaccharides of special composition. The toxicity of phenol compounds, which is manifested under the aerobic conditions, prevents the activity of all the hydrolytic enzymes. This is the main reason for the slow decomposition of sphagnum peat and the long-term preservation of the residues of bodies and food in high-moor peatlands.

    2013-06-01

    Floating production storage and offloading (FPSO) facilities are used at most of the offshore oil fields worldwide. FPSO usage is expected to grow as oil fields move to deeper water, thus requiring the reliability and stability of mooring wires and risers in extreme environmental conditions. Except for the case of predictable attack angles of external loadings, FPSO facilities with turret single point mooring (SPM) systems are in general use. There are two types of turret systems: permanent systems and disconnectable turret mooring systems. Extreme environment criteria for permanent moorings are usually based on a 100-year return period event. It is common to use two or three environments including the 100-year wave with associated wind and current, and the 100-year wind with associated waves and current. When fitted with a disconnectable turret mooring system, FPSOs can be used in areas where it is desirable to remove the production unit from the field temporarily to prevent exposure to extreme events such as cyclones or large icebergs. Static and dynamic mooring analyses were performed to evaluate the stability of a spider buoy after disconnection from a turret during cyclone environmental conditions

    More than Moore explores a new area of Silicon based microelectronics, which reaches beyond the boundaries of conventional semiconductor applications. Creating new functionality to semiconductor circuits, More than Moore focuses on motivating new technological possibilities. In the past decades, the main stream of microelectronics progresses was mainly powered by Moore's law, with two focused development arenas, namely, IC miniaturization down to nano scale, and SoC based system integration. While the microelectronics community continues to invent new solutions around the world to keep Moore's law alive, there is increasing momentum for the development of 'More than Moore' technologies which are based on silicon technologies but do not simply scale with Moore's law. Typical examples are RF, Power/HV, Passives, Sensor/Actuator/MEMS or Bio-chips. The More than Moore strategy is driven by the increasing social needs for high level heterogeneous system integration including non-digital functions, the necessity to speed up innovative product creation and to broaden the product portfolio of wafer fabs, and the limiting cost and time factors of advanced SoC development. It is believed that More than Moore will add value to society on top of and beyond advanced CMOS with fast increasing marketing potentials. Important key challenges for the realization of the 'More than Moore' strategy are: perspective materials for future THz devices materials systems for embedded sensors and actuators perspective materials for epitaxial approaches material systems for embedded innovative memory technologies development of new materials with customized characteristics The Hot topics covered by the symposium M (More than Moore: Novel materials approaches for functionalized Silicon based Microelectronics) at E-MRS 2012 Spring Meeting, 14-18 May 2012 have been: development of functional ceramics thin films New dielectric materials for advanced microelectronics bio- and CMOS compatible

    An experimental study of the effect of mooring systems on the dynamics of a SPAR buoy-type floating offshore wind turbine is presented. The effects of the Center of Gravity (COG), mooring line spring constant, and fair-lead location on the turbine's motion in response to regular waves are investigated. Experimental results show that for a typical mooring system of a SPAR buoy-type Floating Offshore Wind Turbine (FOWT), the effect of mooring systems on the dynamics of the turbine can be considered negligible. However, the pitch decreases notably as the COG increases. The COG and spring constant of the mooring line have a negligible effect on the fairlead displacement. Numerical simulation and sensitivity analysis show that the wind turbine motion and its sensitivity to changes in the mooring system and COG are very large near resonant frequencies. The test results can be used to validate numerical simulation tools for FOWTs.

The effects of the Center of Gravity (COG), mooring line spring constant, and fair-lead location on the turbine's motion in response to regular waves are investigated. Experimental results show that for a typical mooring system of a SPAR buoy-type Floating Offshore Wind Turbine (FOWT), the effect of mooring systems on the dynamics of the turbine can be considered negligible. However, the pitch decreases notably as the COG increases. The COG and spring constant of the mooring line have a negligible effect on the fairlead displacement. Numerical simulation and sensitivity analysis show that the wind turbine motion and its sensitivity to changes in the mooring system and COG are very large near resonant frequencies. The test results can be used to validate numerical simulation tools for FOWTs.

  1. Geology and mineral deposits of the Minnie Moore and Bullion mineralized areas, Blaine County, Idaho

    In the early 1880?s the discovery of rich ores in the Minnie Moore and Bullion mineralized areas sparked a rush to settle and develop the Wood River valley. Silver and lead discoveries in these areas spurred the boom in mining after completion of the Oregon Short Line Railroad to Hailey in 1883. In both areas the ore comprises galena, sphalerite, and tetrahedrite in a gangue of siderite, calcite, or quartz. Minor goldbearing quartz veins are also present. The ore is in fissure and replacement veins along fracture systems that formed in Late Cretaceous time, after intrusion of nearby granodiorite or quartz diorite stocks. The ore formed under mesothermal conditions and heat was supplied by the nearby plutons. In the Minnie Moore area, the mineralized veins are cut by low-angle normal faults that are of probable Eocene age. In the Minnie Moore mineralized area, the host rock is the middle part of the Devonian Milligen Formation, (the informal Lucky Coin limestone and Triumph argillite), which is the same stratigraphic level as the host ore in the rich Triumph mine northeast of Hailey. In the Bullion mineralized area, the ore is hosted by the lower member of the Middle Pennsylvanian to Lower Permian Dollarhide Formation. Rich ore was mined in several tunnels that reached the Mayflower vein, a northwest-striking mineralized shear zone. The deposits are thought to be mainly mesothermal veins that formed in association with Cretaceous magmatism. The syngenetic stratiform model of ore formation has often been applied to these deposits, however, no evidence of syngenetic mineralization was found in this study. Faulting has displaced most of the major orebodies and thus has made mining these deposits a challenge.

    This paper presents the design and structural details of two mooring masts, one for remotely controlled outdoor airships and another one for remotely controlled indoor airships. In a previous study, a mast for outdoor remotely controlled airship was designed to meet several user-specified operating requirements, and a simplified version of the same was fabricated. A spring loaded device was incorporated that sounds an alarm when the wind-loads exceed a threshold value, so that the airship can be taken indoors. The present study started with a critical analysis of that mast, and a new mast was designed and fabricated to remove several of its shortcomings. This mast consists of power screw operated telescopic module made of aluminium, mounted on a five legged base with castor wheels, for ease in mobility. Components of the existing mast were used to the possible extent, and the design was simplified to meet the assembly and transportation requirements. The spring mechanism used in alarming device was also modified to ensure higher sensitivity in the range of maximum expected wind-loads acting on the airship. A lightweight mooring mast for indoor remotely controlled airships was also designed and fabricated, which can accommodate non-rigid indoor airships of length up to 5 m. The mast consists of an elevating bolt operated telescopic module mounted on a tripod adapter base, with lockable castor wheels, and has a specially designed mooring-clamp at the top. The various modules and components of the mast were designed to enable quick assembly and transportation.

    This paper describes the design and performance of a two-dimensional moored array for sampling horizontal variability in the upper ocean. The mooring was deployed in Massachusetts Bay in a water depth of 84 m for the purpose of measuring the horizontal structure of internal waves. The mooring was instrumented with three acoustic current meters (ACMs) spaced along a 170-m horizontal cable that was stretched between two subsurface buoys 20 m below the sea surface. Five 25-m-long vertical instrument strings were suspended from the horizontal cable. A bottom-mounted acoustic Doppler current profiler (ADCP) was deployed nearby to measure the current velocity throughout the water column. Pressure sensors mounted on the subsurface buoys and the vertical instrument strings were used to measure the vertical displacements of the array in response to the currents. Measurements from the ACMs and the ADCP were used to construct time-dependent, two-dimensional current fields. The current fields were used as input to a numerical model that calculated the deformation of the array with respect to the nominal zero-current configuration. Comparison of the calculated vertical offsets of the downstream subsurface buoy and downstream vertical instrument string with the pressure measurements were used to verify the numerical code. These results were then used to estimate total deformation of the array due to the passage of the internal waves. Based on the analysis of the three internal wave events with the highest measured vertical offsets, it is concluded that the geometry of the main structure (horizontal cable and anchor legs) was kept to within ±2.0 m, and the geometry of the vertical instrument strings was kept to within ±4.0 m except for one instance when the current velocity reached 0.88 m s−1.

    2008-01-01

    The media reporting on Sicko, Michael Moore's documentary about the failures of the U.S. health care system, provides an example of how corporate media continue to twist and restrict the much-needed debate on health care reform. Aside from an occasional concession that having 46 million uninsured Americans is indeed problematic, the media's hype-filled conversation on health care avoids the issues and echoes old myths about the dangers of "government-run" and "socialized" health care. But in the face of the media demonization, universal health care is remarkably popular among the public. PMID:18341130

    2008-01-01

    Background This methodological article is based on a health policy research project conducted in Burkina Faso (West Africa). Concept mapping (CM) was used as a research method to understand the local views of equity among stakeholders, who were concerned by the health policy under consideration. While this technique has been used in North America and elsewhere, to our knowledge it has not yet been applied in Africa in any vernacular language. Its application raises many issues and certain methodological limitations. Our objective in this article is to present its use in this particular context, and to share a number of methodological observations on the subject. Methods Two CMs were done among two different groups of local stakeholders following four steps: generating ideas, structuring the ideas, computing maps using multidimensional scaling and cluster analysis methods, and interpreting maps. Fifteen nurses were invited to take part in the study, all of whom had undergone training on health policies. Of these, nine nurses (60%) ultimately attended the two-day meeting, conducted in French. Of 45 members of village health committees who attended training on health policies, only eight were literate in the local language (Moore). Seven of these (88%) came to the meeting. Results The local perception of equity seems close to the egalitarian model. The actors are not ready to compromise social stability and peace for the benefit of the worst-off. The discussion on the methodological limitations of CM raises the limitations of asking a single question in Moore and the challenge of translating a concept as complex as equity. While the translation of equity into Moore undoubtedly oriented the discussions toward social relations, we believe that, in the context of this study, the open-ended question concerning social justice has a threefold relevance. At the same time, those limitations were transformed into strengths. We understand that it was essential to resort to the

    1975-01-01

    In a retrospective computerized study of 451 Austin Moore arthroplasties (211 for acute hip fractures and 240 for hip reconstruction), the operative and general complications were correlated with the historical, preoperative, operative, and early and late postoperative factors usually thought to influence the results. Wound complications were significantly associated with diabetes and fracture, obesity and fracture, and procedures lasting two hours or more. General complications showing significant associations were: death or pneumonia with fractures, phlebitis with obesity, and myocardial infarction with fracture. Factors not significantly associated with complications included age, previous hip surgery, time of day of the operation, surgical approach, wound irrigation, use of drains, postoperative anticoagulation, and reaming of the acetabulum.

    The number, potential viability, and taxonomic diversity (at the level of phylum) of the filterable forms of prokaryotes (FFP) are estimated in the main genetic horizons of high-moor peat. It was shown that the number of FFP reached 500 million cells in 1 g, i.e., up to 5% of the general size bacteria. The portion of viable cells among FFP (93-98%) was higher than that for the general size bacteria (60-68%). FISH-analysis (fluorescence in situ hybridization) showed that FFP contained the same phylogenetic groups as the population of general size bacteria (domain Archea and phylum Actinobacteria, Cytophaga, and Proteobacteria of the domain Bacteria).

    Analyzing the dynamic response and calculating the tendon tension of the mooring system are necessary for the structural design of a tension leg platform (TLP). The six-degree-of-freedom dynamic coupling responses and the mooring characteristics of TLP under random waves are studied by using a self-developed program. Results are verified by the 1:40 scaling factor model test conducted in the State Key Laboratory of Ocean Engineering at Shanghai JiaoTong University. The mean, range, and standard deviation of the numerical simulation and model test are compared. The influences of different sea states and wave approach angles on the dynamic response and tendon tension of the mooring system are investigated. The acceleration in the center and corner of the deck is forecasted.

  11. Numerical investigation of mooring line damping and the drag coefficients of studless chain links

    Xu, Zhengqiang; Huang, Shan

    2014-03-01

    The chain/wire rope/chain combination is a common choice for mooring offshore floating platforms. However, data of the drag coefficients of chain links are rather limited, resulting in uncertainties with the calculations of the drag force, and hence the damping of the mooring system. In this paper, the importance of the selection of the drag coefficient is first investigated. The computational fluid dynamics (CFD) method is then used to determine the drag coefficients of a studless chain under steady flows. Numerical model validation is first completed by simulating a smooth circular cylinder under steady flows. In particular, the performance of different turbulence models is assessed through the comparisons between the calculations and the experimental results. The large eddy simulation (LES) model is finally selected for the simulation of steady flows past a chain. The effects of the Reynolds number on the drag coefficient of a stud-less chain is also studied. The results show that the calculated drag coefficients of a stud-less chain are fairly consistent with the available experimental data.

    In the early afternoon of 20 May 2013, a storm initiated to the west-southwest of Newcastle, Oklahoma. This storm would rapidly intensify into the parent supercell of the tornado that struck the city of Moore, Oklahoma. This article describes what contributions total lightning observations from the Oklahoma Lightning Mapping Array could provide to operational forecasters had these observations been available in real-time. This effort includes a focus on the GOES-R pseudo-geostationary lightning mapper demonstration product as well as the NASA SPoRT / Meteorological Development Laboratory's total lightning tracking tool. These observations and tools identified several contributions. Two distinct lightning jumps at 1908 and 1928 UTC provided a lead time of 19 minutes ahead of severe hail and 26 minutes ahead of the Moore, Oklahoma tornado's touchdown. These observations provide strong situational awareness to forecasters, as the lightning jumps are related to the rapid strengthening of the storm's updraft and mesocyclone and serve as a precursor to the stretching of the storm vortex ahead severe weather.

    2014-01-01

    For five decades, the semiconductor industry has distinguished itself by the rapid pace of improvement in miniaturization of electronics products-Moore's Law. Now, scaling hits a brick wall, a paradigm shift. The industry roadmaps recognized the scaling limitation and project that packaging technologies will meet further miniaturization needs or ak.a "More than Moore". This paper presents packaging technology trends and accelerated reliability testing methods currently being practiced. Then, it presents industry status on key advanced electronic packages, factors affecting accelerated solder joint reliability of area array packages, and IPC/JEDEC/Mil specifications for characterizations of assemblies under accelerated thermal and mechanical loading. Finally, it presents an examples demonstrating how Accelerated Testing and Analysis have been effectively employed in the development of complex spacecraft thereby reducing risk. Quantitative assessments necessarily involve the mathematics of probability and statistics. In addition, accelerated tests need to be designed which consider the desired risk posture and schedule for particular project. Such assessments relieve risks without imposing additional costs. and constraints that are not value added for a particular mission. Furthermore, in the course of development of complex systems, variances and defects will inevitably present themselves and require a decision concerning their disposition, necessitating quantitative assessments. In summary, this paper presents a comprehensive view point, from technology to systems, including the benefits and impact of accelerated testing in offsetting risk.

  14. Diel vertical migration of zooplankton at the S1 biogeochemical mooring revealed from acoustic backscattering strength

    We examined the diel vertical migration of zooplankton by using the backscatter strength obtained from moored acoustic Doppler current profilers at mooring site S1 in the North Pacific subtropical gyre. There was seasonal variability in the vertical distribution and migration of the high-backscatter layers in that they became deeper than the euphotic zone (<100 m) in winter and were confined above this depth in other seasons. Seasonal changes in daylight hours also affected the timing of the diel migration. We found that lunar cycles affected vertical distributions of zooplankton near the surface by changing the light intensity. Physical events, such as mixed-layer deepening and restratification and the passage of a mesoscale eddy, also affected zooplankton behavior possibly by changing food environment in the euphotic zone. Since the comparison with net samples indicated that the backscatter likely represents the bulk biomass, the accuracy of biomass estimates based on net samples could be influenced by the high temporal variability of zooplankton distributions.

  15. Line-edge roughness and the impact of stochastic processes on lithography scaling for Moore's Law

    NASA Astrophysics Data System (ADS)

    Mack, Chris A.

    2014-09-01

    Moore's Law, the idea that every two years or so chips double in complexity and the cost of a transistor is always in decline, has been the foundation of the semiconductor industry for nearly 50 years. The main technical force behind Moore's Law has been lithography scaling: shrinking of lithographic features at a rate faster than the increase in finished wafer costs. With smaller feature size comes the need for better control of those sizes during manufacturing. Critical dimension and overlay control must scale in proportion to feature size, and has done so for the last 50 years. But in the sub-50-nm feature size regime, a new problem has arisen: line-edge roughness due to the stochastic nature of the lithography process. Despite significant effort, this line-edge roughness has not scaled in proportion to feature size and is thus consuming an ever larger fraction of the feature size control budget. Projection of current trends predicts a collision course between lithography scaling needs and line-edge roughness reality. In the end, stochastic uncertainty in lithography and its manifestation as line-edge roughness will prove the ultimate limiter of resolution in semiconductor manufacturing.

  16. Moored observations of synoptic and seasonal variability in the East Greenland Coastal Current

    NASA Astrophysics Data System (ADS)

    Harden, B. E.; Straneo, F.; Sutherland, D. A.

    2014-12-01

    We present a year-round assessment of the hydrographic variability within the East Greenland Coastal Current on the Greenland shelf from five synoptic crossings and 4 years of moored hydrographic data. From the five synoptic sections the current is observed as a robust, surface intensified flow with a total volume transport of 0.66 ± 0.18 Sv and a freshwater transport of 42 ± 12 mSv. The moorings showed heretofore unobserved variability in the abundance of Polar and Atlantic water masses in the current on synoptic scales. This is exhibited as large vertical displacement of isotherms (often greater than 100 m). Seasonally, the current is hemmed into the coast during the fall by a full depth Atlantic Water layer that has penetrated onto the inner shelf. The Polar Water layer in the current then thickens through the winter and spring seasons increasing the freshwater content in the current; the timing implies that this is probably driven by the seasonally varying export of freshwater from the Arctic and not the local runoff from Greenland. The measured synoptic variability is enhanced during the winter and spring period due to a lower halocline and a concurrent enhancement in the along-coast wind speed. The local winds force much of the high-frequency variability in a manner consistent with downwelling, but variability distinct from downwelling is also visible.

    Results from a 2-year (nominal) deployment of a moored array along 152 deg E from 28 deg N to 41 deg N are presented, with emphasis on similarities and differences between settings (approximately year-to-year). Ten moorings and 38 instruments were involved, from the fall of 1980 to 1982. Current-temperature meters spanned the water column from 500- to 4000-m depths, with occasional instruments in the vicinity of 300 m and near the bottom (about 6000 m). Upper level features located in the center of the array near 35-36 deg N were generally stable relative to the axis of the Kuroshio Extension, varying from deployment to deployment with meanders in this flow regime. Some properties of the abyssal (about 4000 m) currents were comparatively more variable, with these changes not connected to meandering of the Kuroshio Extension in an obvious way. The vertical structure and frequency distributions of eddy kinetic energy were similar in shape and to some extent in amplitude from deployment to deployment, especially relative to meanders of the Kuroshio Extension, but translated in the opposite direction.

    It has been recognized that optical moorings are important platforms for the validation of Sea-Viewing Wide Field-of-view Sensor (SeaWiFS). It was recommended that optical moorings be maintained in order to: (1) provide long-term time series comparisons between in situ and SeaWIFS measurements of normalized water-leaving radiance; (2) develop and test algorithms for pigment biomass and phytoplankton primary productivity; and (3) provide long-term, virtually continuous in situ observations which can be used to determine and optimize the accuracy of derived satellite products. These applications require the use of in situ radiometers for long periods of time to evaluate and correct for inherent satellite undersampling (aliasing and biasing) and degradation of satellite color sensors (e.g., drifts as experienced by the Coastal Zone Color Scanner). The Bermuda Testbed Mooring (BTM) program was initiated in 1994 at a site located about 80km southeast of Bermuda in waters of about 4530 m depth. In August 1997, with NASA's support, we started to provide the Sensor Intercomparison and Merger for Biological and Interdisciplinary Oceanic Studies (SIMBIOS) program with large volumes of high frequency, long-term time-series bio-optical data from the BTM for SeaWiFS satellite ocean color groundtruthing and algorithm development. This NASA supported portion of the BTM activity spanned three years and covered five BTM deployments. During these three years, the quality of radiometric data has improved dramatically. Excellent agreement between BTM moored data and both SeaWiFS and nearby ship profile radiometric data demonstrate that technical advances in the moored optical observations have reduced the major difficulties that moored platforms face: biofouling and less frequent calibration.

  19. Sensitivity analysis of air gap motion with respect to wind load and mooring system for semi-submersible platform design

    2016-07-01

    A design of semi-submersible platform is mainly based on the extreme response analysis due to the forces experienced by the components during lifetime. The external loads can induce the extreme air gap response and potential deck impact to the semi-submersible platform. It is important to predict air gap response of platforms accurately in order to check the strength of local structures which withstand the wave slamming due to negative air gap. The wind load cannot be simulated easily by model test in towing tank whereas it can be simulated accurately in wind tunnel test. Furthermore, full scale simulation of the mooring system in model test is still a tuff work especially the stiffness of the mooring system. Owing to the above mentioned problem, the model test results are not accurate enough for air gap evaluation. The aim of this paper is to present sensitivity analysis results of air gap motion with respect to the mooring system and wind load for the design of semi-submersible platform. Though the model test results are not suitable for the direct evaluation of air gap, they can be used as a good basis for tuning the radiation damping and viscous drag in numerical simulation. In the presented design example, a numerical model is tuned and validated by ANSYS AQWA based on the model test results with a simple 4 line symmetrical horizontal soft mooring system. According to the tuned numerical model, sensitivity analysis studies of air gap motion with respect to the mooring system and wind load are performed in time domain. Three mooring systems and five simulation cases about the presented platform are simulated based on the results of wind tunnel tests and sea-keeping tests. The sensitivity analysis results are valuable for the floating platform design.

    A new strategy of multi-objective structural optimization is integrated into Austin-Moore prosthesis in order to improve its performance. The new resulting model is so-called Improved Austin-Moore. The topology optimization is considered as a conceptual design stage to sketch several kinds of hollow stems according to the daily loading cases. The shape optimization presents the detailed design stage considering several objectives. Here, A new multiplicative formulation is proposed as a performance scale in order to define the best compromise between several requirements. Numerical applications on 2D and 3D problems are carried out to show the advantages of the proposed model. PMID:27028554

    The Shelf Edge Exchange Processes (SEEP) program sponsored by the United States Department of Energy is a multi-institutional effort designed to investigate the flux of suspended material from the continental shelf to the waters of the upper slope, and then possibly into the slope sediments. The first SEEP experiment (SEEP I) was across the outer continental shelf of New England during 1983--1984 and consisted of a series of nine cruises and a mooring array. The second experiment (SEEP II) focused specifically of the shelf/slope frontal region of the mid-Atlantic Bight off the Delmarva peninsula. This report presents data collected during SEEP II. The SEEP II experiment consisted of a series of ten cruises and mooring arrays as well as over-flights by NASA aircraft. The cruises were consecutively designated SEEP2-01 to SEEP2-10. Hydrographic data were collected on all cruises except SEEP2-04 and SEEP2-07 during which benthic processes were investigated. Mooring arrays were deployed during three cruises in the Spring, Summer and Winter of 1988. Brookhaven National Laboratory deployed sixteen fluorometer instrument packages on their moorings with sensors to measure: the in vivo fluorescence of phytoplankton, temperature, subsurface light, dissolved oxygen, and water transparency. Data from the fluorometer, temperature, and transmissometer sensors are reported herein.

    2011-03-01

    We discuss the life and career of Willie Hobbs Moore, the first African American woman to receive a doctorate degree in physics. This achievement occurred in June 1972 at the University of Michigan, Ann Arbor, MI. Her dissertation, directed by the renowned spectroscopist Samuel Krimm, was on the subject of ``A Vibrational Analysis of Secondary Chlorides," and focused on a theoretical analysis of the secondary chlorides for polyvinal-chlorine polymers. From 1972--1977, she, Krimm, and collaborators published more than thirty papers on this and related research issues. In addition to an overview of her family background, her careers as a research physicist and scientist working in various industrial laboratories, we discuss the obstacles and successes she encountered at various stages of her life.

    A field demonstration and longevity assessment for long-term monitoring of the explosive 2,4,6-trinitrotoluene (TNT) in a marine environment using an anti-TNT microfluidic immunosensor is described. The TNT immunosensor is comprised of a microfluidic device with 39 parallel microchannels (2.5 cm × 250 µm × 500 µm, L × W × D) fabricated in poly(methylmethacrylate) (PMMA), then chemically functionalized with antibodies possessing a high affinity for TNT. Synthesized fluorescence reporter complexes used in a displacement-based assay format were used for TNT identification. For field deployment the TNT immunosensor was configured onto a submersible moored steel frame along with frame controller, pumps and TNT plume generator and deployed pier side for intermittent plume sampling of TNT (1h increments). Under varying current and tidal conditions trace levels of TNT in natural seawater were detected over an extended period (>18 h). Overnight operation and data recording was monitored via a web interface.

    1979-01-01

    Thin sections and single grains of pyroxenes from the Serra de Mage feldspar cumulate eucrites were studied by X-ray crystallography, electron microprobe and optical techniques. It was concluded that the pyroxene crystallized as pigeonite. On cooling augite was exsolved along (001) and inverted to hypersthene, with exsolution of (100) augite from hypersthene during continued slow cooling. The estimated original bulk composition of the pigeonite pyroxene is Wo10En51Fs39. The compositional data, textural relations, and existence of P2 sub 1 ca hypersthene suggest very low cooling (about 0.0004 deg C/year) below 800 deg. The Serra de Mage augite lamellae were found to be as thick or thicker than those of Moore County and Moama meteorites.

    2016-04-01

    We are interested in the Moore-Gibson-Thompson equation with memory τ{u}_{ttt}+ α u_{tt}+c2Au+bAu_t -int_0tg(t-s)A w(s){d}s=0. This model arises in high-frequency ultrasound applications accounting for thermal flux and molecular relaxation times. According to revisited extended irreversible thermodynamics, thermal flux relaxation leads to the third-order derivative in time while molecular relaxation leads to non-local effects governed by memory terms. The resulting model is of hyperbolic type with viscous effects. We first classify the memory into three types. Then, we study how a memory term creates damping mechanism and how the memory causes energy decay even in the cases when the original memoryless system is unstable.

    2016-05-01

    A unique small-scale 3-D mooring array has been designed consisting of five parallel lines, 100 m long and 4 m apart, and holding up to 550 high-resolution temperature sensors. It is built for quantitative studies on the evolution of stratified turbulence by internal wave breaking in geophysical flows at scales which go beyond that of a laboratory. Here we present measurements from above a steep slope of Mount Josephine, NE Atlantic where internal wave breaking occurs regularly. Vertical and horizontal coherence spectra show an aspect ratio of 0.25-0.5 near the buoyancy frequency, evidencing anisotropy. At higher frequencies, the transition to isotropy (aspect ratio of 1) is found within the inertial subrange. Above the continuous turbulence spectrum in this subrange, isolated peaks are visible that locally increase the spectral width, in contrast with open ocean spectra. Their energy levels are found to be proportional to the tidal energy level.

  5. Bone lead levels and lead isotope ratios in red grouse from Scottish and Yorkshire moors.

    2009-05-15

    Leg and foot bones of adult and juvenile red grouse (Lagopus lagopus scoticus) were collected from hunter-shot birds on two Scottish estates (Glendye and Invermark) and one Yorkshire estate in September, 2003. The lead content of bones was measured by atomic absorption spectrophotometry, and corresponding stable lead isotopes (Pb(204, 206, 207, 208)) by inductively coupled plasma mass spectrometry. At the Glendye (N=111) and Invermark (N=85) estates, relatively few birds (5.4% and 3.5%, respectively) had highly elevated bone lead concentrations (>20 microg/g dry weight). In bones of these highly exposed birds, a combination of Pb(206):Pb(207) and Pb(208):Pb(207)ratios was consistent with ingestion of lead gunshot available in Europe. By contrast, Yorkshire grouse experienced a high incidence (65.8%) of bone lead >20 microg/g. The Pb(206):Pb(207) and Pb(208):Pb(207)ratios in bones of these highly exposed birds were consistent with a combined exposure to ingested lead gunshot and lead from galena mining in the region. Lead isotope ratios also indicated that lead from UK gasoline combustion and fallout from atmospheric particles was not a likely source of elevated lead in bones of either Scottish or Yorkshire grouse. Suggested management options for the three moors include adopting nontoxic shot for all game shooting on the estates, allowing heather (Calluna vulgaris) vegetation to grow tall in lead shot fall-out zones to reduce physical access to high densities of lead shot already present, and provision of calcareous grit across moors to reduce lead assimilation from all ingested sources of lead.

  6. The Brenner Moor - A saline bog as a source for halogenated and non-halogenated volatile compounds

    The Brenner Moor is a small bog in the catchment area of the river Trave located in Schleswig-Holstein, North Germany, between Baltic and North Sea. The bog is fed by several saline springs with chloride concentrations up to 15 g/L. The high chloride concentrations and the high organic content of the peat make the Brenner Moor an ideal source for the abiotic formation of volatile organic halogenated compounds (VOX). VOX play an important role in the photochemical processes of the lower atmosphere and information on the atmospheric input from saline soils like the Brenner Moor will help to understand the global fluxes of VOX. Soil samples were taken in spring 2011 from several locations and depths in the vicinity of the Brenner Moor. The samples were freeze-dried, ground and incubated in water emphasising an abiotic character for the formation of volatile organic compounds. 1,2-dichloroethane and trichloromethane are the main halogenated compounds emitted from soils of the Brenner Moor. The abiotic formation of trichloromethane as well as other trihalomethanes has been part of intensive studies. A well known source is the decarboxylation of trichloroacetic acid and trichloroacetyl-containing compounds to trichloromethane [1]. Huber et al. discovered another pathway in which catechol, as a model compound for organic substances, is oxidised under Fenton-like conditions with iron(III), hydrogen peroxide and halides to form trihalomethanes [2]. Besides the halogenated compounds, the formation of sulphur compounds such as dimethyl sulfide and dimethyl disulfide and several furan derivatives could be detected which also have an impact on atmospheric chemistry, especially particle formation of clouds. Furan, methylfuran and dimethylfuran are compounds that can be obtained under Fenton-like oxidation from catechol, methyl- and dimethylcatechol and are known to be produced in natural soils [3]. A novel class of furan derivatives that are formed under abiotic conditions from

    2016-04-01

    The Royal Netherlands Institute for Sea Research has been developing for several years a family of temperature sensors (NIOZ1 to NIOZ5). In the latest iterations of this project, these instruments are precise (10‑3 K or better), have a very low noise level (below 10‑3 K), are relatively fast (sampling rate of 1Hz) and can measure for extended periods of time (several months). Being also compact and lightweight, several thermistors can be attached on a single line at a fine vertical spacing (20cm or more). When mounted on a cable, the instruments are all synchronised to a single clock, thus providing simultaneous measurements throughout the depth range of the mooring (usually in the order of 100m). Recently, the instruments have also been deployed in a group of 5 lines approximately 5m apart from each other, providing a unique view on the three-dimensional temperature field. After almost 10 years of successful deployments at sea, we try to draw some conclusions from this effort, from the scientific and technical point of view. This observational system provides temperature measurements with vertical spatial resolution comparable to that of microstructure profilers, but in comparison to ship-borne systems it offers some distinctive features: providing instantaneous measurements throughout the mooring, observations of waves and overturning structures are not influenced by the time delay between measurements at different depths; the very low noise level and high precision enables the study of the deep, weakly stratified ocean; by using a heavy ballast at the bottom and a high net buoyancy at the top of the mooring, Eulerian measurements are effectively obtained; continuous, high sampling rate Eulerian measurements enable to assess the intermittent, sporadic nature of turbulence and wave activity in the ocean; the large range of time scales included in the observations (100 ‑ 106 s) allows to study a large portion of the turbulence inertial range, the full

    The presentation will provide the technical specifications, the systems engineering processes, and preliminary results from laboratory and field tests, as the National Data Buoy Center (NDBC) undertakes a fundamental and broad transformation (sea-change) of its ocean observing systems on moored buoys. This transformation is necessary to gain efficiencies in maintaining operational ocean observation networks and to increase their reliability, which will reduce maintenance costs. The presentation will also compare and contrast existing and planned systems. The Self-Contained Ocean Observations Payload (SCOOP) takes advantage of the advances in communications and small, efficient, multi-purpose sensors to reduce the size and costs of systems and expand the suite of available real-time ocean observations. The communications will allow NDBC to increase the precision and decrease the latency of the observations. The hallmark of SCOOP is the modularity of the payloads that allow NDBC to host specialized systems, for the oceanographic research community, which may include observing ocean acidification and algal blooms, and tracking marine life, alongside its standard suite of meteorological, oceanographic, and wave systems. SCOOP will include cameras, primarily to document vandalism incidents, but they can also serve to corroborate many of the automatic observations. The two-year integration project - focused on recapitalization of NDBC's network of Hurricane Weather buoys - is aided by NDBC's 40 years of experience with marine observations and its continually improving approach to testing. Testimony to the rigor of NDBC's development and test procedures is that the World Meteorological Organization and the Intergovernmental Ocean Commission have designated NDBC as the first Regional Marine Instrumentation Center (RMIC). Integral to the fielding of these new systems is a Mission Control Center (MCC) performing the real-time, specialized monitoring and analyses and

    A 9-month time series of optical data, composed of three separate deployments, from the Biowatt 1987 deep-sea mooring located in the oligotrophic waters of the Sargasso Sea at 32 deg N, 70 deg W, is presented. These data were analyzed using several biooptical models for the purpose of providing a continuous estimate of the spectral diffuse attenuation coefficient and pigment biomass. Results of the first 70-day deployment demonstrate the utility of optical observations as proxy measures of biological parameters, and facilitate a preliminary analysis of the temporal variations and a comparison of the present biooptical observations with concurrent physical observations. Biooptical properties exhibit variation in response to physical forcings, such as diel variations of incident solar irradiance, episodic wind forcing, advective mesoscale eddy layer depth, and succession of phytoplankton. The mooring data are discussed in the context of contemporaneous shipboard observations as well as in terms of future ocean satellite observations.

    We detected clear concentric waves and short-period oscillations in the ionosphere after an Enhanced Fujita scale (EF)5 tornado hit Moore, Oklahoma, U.S., on 20 May 2013 using dense wide-coverage ionospheric total electron content (TEC) observations in North America. These concentric waves were nondispersive, with a horizontal wavelength of ~120 km and a period of ~13 min. They were observed for more than 7 h throughout North America. TEC oscillations with a period of ~4 min were also observed to the south of Moore for more than 8 h. A comparison between the TEC observations and infrared cloud image from the GOES satellite indicates that the concentric waves and short-period oscillations are caused by supercell-induced atmospheric gravity waves and acoustic resonances, respectively. This observational result provides the first clear evidence of a severe meteorological event causing atmospheric waves propagating upward in the upper atmosphere and reaching the ionosphere.

    The helminths fauna of common spaedfoot Pelobates fuscus (Laurenti, 1768) and moor frog Rana arvalis Nilsson, 1842 has been studied at their joint habitation. The stuff was collected in 1998-2002, 2004-2006 years in several regions (republic Mordovia, Samara and Saratov areas). The processing of a stuff is conducted by a method of full helmintologic dissecting. The fauna of helminths considerably differs. For common spaedfoot only 13 species of helminths was detected which also parasitized moor frog (for moor frog 23 species) are detected. The index Jaccar demonstrated mean resemblance structure of helminths and varied from 0.25 till 0.69, and the index Morisite--from 44.58 of % till 74.51 of %. The communities of parasites of common spaedfoot was characterized by low values of an index of Shannon, but the high indexes of an index Simpson, whereas for moor frog tracked the return tendence.

    The nearshore regions of the Arctic are challenging environments in which to collect long-term oceanographic data. The shallowness of the water means that bottom-moored instruments face the risk of damage by deep-keeled ice ridges, while instruments tethered to the landfast ice are at risk from ice breakout or deformation events. Also, Arctic landfast sea ice is typically seasonal, so ice-tethered moorings can only deployed for part of the year. For these reasons ocean data from beneath Arctic landfast sea ice are sparse. Moreover, the few datasets that have been published suggest that stable, quiescent conditions prevail, which appears to be at odds with traditional knowledge held by indigenous local ice experts who report that currents beneath landfast ice can be strong and be responsible for significant thinning. Here, we present temperature, salinity and current measurements from two moorings deployed in the Chukchi Sea near Barrow, Alaska from August 2009 to August 2011. These data show that currents underneath landfast ice commonly exceeded 20 cm s-1 while break-out events were associated with currents of up to 118 cm s-1. This supports the observations of local hunters in Barrow, who indicate that currents under the landfast ice are the most effective means of destabilizing landfast sea ice. The mooring data also show frequent pulses of water significantly above the freezing point throughout the winter. The similarity of peak temperatures and salinities associated with these pulses suggests they all originate from the same reservoir of warm, saline water. These observations contribute to an integrated sea ice observatory established in Barrow as part of the Seasonal Ice Zone Observing Network (SIZONet; www.sizonet.org). In addition to helping both the scientific community and local residents better understand the processes affecting landfast sea ice stability, these data will also benefit studies of regional sea ice variability, migration of marine mammals

    Temperature, depth and conductivity (CTD) are the most essential physical properties of sea water. CTD instrument is one of the most efficient approaches for collecting the accurate ocean information. However, traditional CTD instruments are not best suited for applications that require high resolution data by a large number of sensors because of their large size and high cost. This paper describes the design of a compact, high-accuracy, and low-cost temperature and depth (TD) logger for ocean mooring system. The noise floor of the TD logger was evaluated in lab for determining the logger measurement resolution. A specific calibration method was implemented for pressure transducer calibration to eliminate the thermal affect. The initial temperature accuracy of the TD logger is ±0.002°C and the pressure accuracy is ±0.05% of full scale. The effective resolution is 0.0001°C and 0.001% full scale for temperature and pressure measurement, respectively. A 150 days off-shore experiment was also conducted to evaluate the stability of TD logger measurement.

Carbon-dioxide (124389) levels were between 450 and 825 parts per million (ppm). Relative humidities ranged from 36 to 50%, and temperatures ranged from 69 to 76 degrees-F. Methylene-chloride (75092) levels ranged from 1.81 to 9.69ppm. NIOSH recommends that levels of the contaminent be reduced as low as possible. The source of the contamination was the extensive use of a type cleaner solvent in a press area. The most prevalent symptoms reported were headache, metallic taste in the mouth, fatigue, nausea and joint pain. The authors conclude that a number of conditions in the Preliminary department may contribute to reported employee symptoms. A potential health hazard existed from exposure to methylene-chloride; an alternative solvent should be substituted. The authors recommend several measures to improve air quality at the site. These include increasing the make up air and humidification, relocating the exhausts and intakes on the roof, maintenance or replacement of an air conditioning unit, and modifications to some of the exhaust hoods.

  18. RAMA: Research Moored Array for African - Asian - Australian Monsoon Analysis and Prediction

    The Indian Ocean is unique among the three tropical oceans in that it is blocked at 25N by the Asian land mass. Seasonal heating and cooling over this land mass sets the stage for dramatic monsoon wind reversals and intense summer rains over areas surrounding the basin. These climate variations have significant societal and economic impacts that affect half the world's population. Despite the importance of the Indian Ocean for both the regional and global climate though, it is the most poorly observed and least well understood of the three tropical oceans. This presentation describes the Research Moored Array for African-Asian-Australian Monsoon Analysis and Prediction (RAMA), which has been designed to provide sustained, basin scale time series data in the Indian Ocean for climate research and forecasting. RAMA is intended to complement other satellite and in situ components of the Indian Ocean Observing System and it is being implemented through a coordinated multi- national effort involving institutions in several countries. We will review the scientific rationale, design criteria, and implementation status of RAMA. We will also illustrate some of the important intraseasonal to interannual time scale phenomena in the region observed with new RAMA time series data. Potential applications of the data for forecasting purposes will also be discussed.

    ABSTRACT Since its discovery the cellular prion protein (encoded by the Prnp gene) has been associated with a large number of functions. The proposed functions rank from basic cellular processes such as cell cycle and survival to neural functions such as behavior and neuroprotection, following a pattern similar to that of Moore's law for electronics. In addition, particular interest is increasing in the participation of Prnp in neurodegeneration. However, in recent years a redefinition of these functions has begun, since examples of previously attributed functions were increasingly re-associated with other proteins. Most of these functions are linked to so-called “Prnp-flanking genes” that are close to the genomic locus of Prnp and which are present in the genome of some Prnp mouse models. In addition, their role in neuroprotection against convulsive insults has been confirmed in recent studies. Lastly, in recent years a large number of models indicating the participation of different domains of the protein in apoptosis have been uncovered. However, after more than 10 years of molecular dissection our view is that the simplest mechanistic model in PrPC-mediated cell death should be considered, as Ockham's razor theory suggested.

    Seven years of near-continuous observations from the Ocean Station Papa (OSP) surface mooring were used to evaluate drivers of marine carbon cycling in the eastern subarctic Pacific. Processes contributing to mixed layer carbon inventory changes throughout each deployment year were quantitatively assessed using a time-dependent mass balance approach in which total alkalinity and dissolved inorganic carbon were used as tracers. By using two mixed layer carbon tracers, it was possible to isolate the influences of net community production (NCP) and calcification. Our results indicate that the annual NCP at OSP is 2 ± 1 mol C m-2 yr-1 and the annual calcification is 0.3 ± 0.3 mol C m-2 yr-1. Piecing together evidence for potentially significant dissolved organic carbon cycling in this region, we estimate a particulate inorganic carbon to particulate organic carbon ratio between 0.15 and 0.25. This is at least double the global average, adding to the growing evidence that calcifying organisms play an important role in carbon export at this location. These results, coupled with significant seasonality in the NCP, suggest that carbon cycling near OSP may be more complex than previously thought and highlight the importance of continuous observations for robust assessments of biogeochemical cycling.

  2. The Ashen Light of Venus: A century of observations by McEwen and Moore

    2007-10-01

    This paper is a catalogue and analysis of the Ashen Light sightings from two remarkably long series of Venus observations held in the BAA Mercury & Venus Section archives spanning 1892 to 1999. The records comprise overlapping series of visual records by the first two Directors of the Section, Henry McEwen and Patrick Moore. The Ashen Light was seen during 25 of the 56 adequately-observed elongations. By analysing the results in terms of the eight-year 'cycle' of Venus elongations we demonstrate that the Ashen Light's visibility does not simply depend upon terrestrial viewing conditions: those elongations that permitted Venus to be viewed at reasonable altitude against a dark sky were not the only occasions when the Light was well seen. At times the phenomenon can become especially conspicuous, as in 1953 and 1956 (when it was visible semi-continuously for more than a month), and in 1895, 1935, 1940, 1957, 1980 and 1988 (where there were fewer good sightings). There also exist long intervals where, despite excellent conditions and observational coverage, the Ashen Light has remained remarkably obscure.

    Autonomous acoustic receivers are often deployed across a range of aquatic habitats to study aquatic species. The Juvenile Salmon Telemetry System autonomous acoustic receiver packages we deployed in the Columbia River and its estuary were comprised of an acoustic receiver, acoustic release, and mooring line sections and were deployed directly on the river bottom. Detection ranges and reception data from past optimization deployments helped determine acoustic receiver spacing in order to achieve acceptable detection probabilities for juvenile salmon survival estimation. Methods used in 2005, which resulted in a high equipment loss rate, were modified and used between 2006 and 2008 to increase crew safety and optimize receiver deployment and recovery operations in a large river system. By eliminating surface buoys and taglines (for anchor recovery), we experienced a recovery success rate greater than previous acoustic receiver deployment techniques used in the Columbia River and elsewhere. This autonomous acoustic receiver system has optimized deployment, recovery, and servicing efficiency to successfully detect acoustic-tagged salmonids in a variety of river environments.

  4. Spatial and temporal variation in efficiency of the Moore egg collector

    The Moore egg collector (MEC) was developed for quantitative and nondestructive capture of semibuoyant fish eggs. Previous studies have indicated that capture efficiency of the MEC was low and the use of one device did not adequately represent the spatial distribution within the water column of egg surrogates (gellan beads) of pelagic broadcast-spawning cyprinids. The objective of this study was to assess whether use of multiple MECs showed differences in spatial and temporal distribution of bead catches. Capture efficiency of three MECs was tested at four 500-m sites on the South Canadian River, a Great Plains river in Oklahoma. For each trial, approximately 100,000 beads were released and mean capture efficiency was 0.47–2.16%. Kolmogorov–Smirnov tests indicated the spatial distributions of bead catches were different among multiple MECs at three of four sites. Temporal variability in timing of peak catches of gellan beads was also evident between MECs. We concluded that the use of multiple MECs is necessary to properly sample eggs of pelagic broadcast-spawning cyprinids.

    A field demonstration and longevity assessment for long-term monitoring of the explosive 2,4,6-trinitrotoluene (TNT) in a marine environment using an anti-TNT microfluidic immunosensor is described. The TNT immunosensor is comprised of a microfluidic device with 39 parallel microchannels (2.5 cm × 250 µm × 500 µm, L × W × D) fabricated in poly(methylmethacrylate) (PMMA), then chemically functionalized with antibodies possessing a high affinity for TNT. Synthesized fluorescence reporter complexes used in a displacement-based assay format were used for TNT identification. For field deployment the TNT immunosensor was configured onto a submersible moored steel frame along with frame controller, pumps and TNT plume generator and deployed pier side for intermittent plume sampling of TNT (1h increments). Under varying current and tidal conditions trace levels of TNT in natural seawater were detected over an extended period (>18 h). Overnight operation and data recording was monitored via a web interface. PMID:24583970

    This study determined the effects of increased N deposition on rates of N and P transformations in an upland moor. The litter layer and the surface of the organic Oh horizon were taken from plots that had received long-term additions of ammonium nitrate at rates of 40, 80 and 120 kg N ha(-1) yr(-1). Net mineralisation processes were measured in both field and laboratory incubations. Soil phosphomonoesterase (PME) activity and rates of N(2)O release were measured in laboratory incubations and root-surface PME activity measured in laboratory microcosms using Calluna vulgaris bioassay seedlings. Net mineralisation rates were relatively slow, with net ammonification consistently stimulated by N addition. Net nitrification was marginally stimulated by N addition in the laboratory incubation. N additions also increased soil and root-surface (PME) activity and rates of N(2)O release. Linear correlations were found between litter C:N ratio and all the above processes except net nitrification in field incubations. When compared with data from a survey of European forest sites, values of litter C:N ratio were greater than a threshold below which substantial, N input-related increases in net nitrification rates occurred. The maintenance of high C:N ratios with negligible rates of net nitrification was associated with the common presence of ericaceous litter and a mor humus layer in both this moorland as well as the forest sites.

    Moored geostrophic measurements are receiving increased attention in oceanic monitoring applications as they yield a horizontally integrated measure of the volume transport. Thus, they provide an inexpensive tool for climate research. Examples of ongoing or planned applications of this technique include the German MOVE experiment in the tropical Atlantic (operating since 2000) and a joint UK/US program designed to monitor the Atlantic meridional overturning circulation at 26.5 N (starting in 2004). This paper shows an earlier practical application of this approach in the Atlantic deep western boundary current at 26.5 N off Abaco, Bahamas, based on data collected within the framework of the ACCP (Atlantic Climate Change Program) between November 95 and June 97. We present the underlying methodology and describe the transport variability observed in the Deep Western Boundary Current by the moored geostrophic technique. Near-boundary transport fluctuations exceeding at times 40 Sv are found on a monthly scale, partly compensated by flow reversals further offshore. The signals are mainly barotropic but a significant baroclinic contribution on longer time scales is also observed. These geostrophic transports are compared to simultaneously acquired moored transports derived from current meter measurements, which proves the feasibility of the geostrophic approach. The array configuration also allows an extended error analysis of both methods (direct vs. geostrophic), which shows a comparable accuracy of both techniques and agreement within the estimated errors.

    To enable offshore floating wind turbine design, the following are required: accurate modeling of the wind turbine structural dynamics, aerodynamics, platform hydrodynamics, a mooring system, and control algorithms. Mooring and anchor design can appreciably affect the dynamic response of offshore wind platforms that are subject to environmental loads. From an engineering perspective, system behavior and line loads must be studied well to ensure the overall design is fit for the intended purpose. FAST (Fatigue, Aerodynamics, Structures and Turbulence) is a comprehensive simulation tool used for modeling land-based and offshore wind turbines. In the case of a floating turbine, continuous cable theory is used to emulate mooring line dynamics. Higher modeling fidelity can be gained through the use of finite element mooring theory. This can be achieved through the FASTlink coupling module, which couples FAST with OrcaFlex, a commercial simulation tool used for modeling mooring line dynamics. In this application, FAST is responsible for capturing the aerodynamic loads and flexure of the wind turbine and its tower, and OrcaFlex models the mooring line and hydrodynamic effects below the water surface. This paper investigates the accuracy and stability of the FAST/OrcaFlex coupling operation.

  10. Conflict of spatial development and water supply under climate change in case of water dependent ecosystem of Ljubljana Moor

    Water resources are vulnerable to climate change and to many other socio-economic drivers of change. A key aspect of vulnerability is that it is spatially variable, reflecting variations of physical and socio-economic conditions. Given the real representation of vulnerability and a set of climate change adaptation options there is need to develop a common transnational strategy for vulnerability reduction. The latter is the goal of SEE CC-WARE project. Among others, ecosystem services, land use change, improving water use efficiency and economic incentives for water management have large potentials to decrease water resources vulnerability. Especially, forests, wetlands and grasslands are important ecosystems, which together with their management emerged as an important means for a sustainable future drinking water supply. The Ljubljana Moor is one of the biggest and most important complexes of wet meadows in Slovenia, which have, due to land use high biodiversity. The Ljubljana Moor extends from the southern part of Ljubljana, the capital of Slovenia, where in the last two centuries extensive irrigation and river regulation projects were implemented to develop agricultural land. Biodiversity of the area is high due to large zones of wet meadows, some flood forest patches, bog areas, and open water courses habitats. The Ljubljana Moor is therefore protected as Natura 2000 site. The Ljubljana Moor is changing very fast and impacts are especially intense in the present years, mostly due to spreading of urbanization and monocultures. In this area the water well field Brest has been designed as important future drinking water source for Ljubljana, pumping mainly water from confined aquifer. The pressure from urbanisation and agriculture and high subsidence that are noticed in the central and eastern part of the aquifer, those two phenomena pose high risk to stable drinking water supply and wetland habitats that are protected as NATURA 2000.

    NASA's Sea-Viewing Wide Field-of-View Sensor (SeaWiFS) aims to measure global ocean color from space to within 5% to provide insights into fundamental ocean processes. SeaWiFS must be backed by comprehensive calibration and validation programs if the mission is to achieve this. In situ measurements of normalized water-leaving radiance (L(sub wn)) made simultaneously with satellite measurements can complement on-orbit methods of tracking changes in the calibration of the satellite radiometer and allow end-to-end vicarious validation of the remotely-sensed data. A moored optical databuoy was developed at Plymouth Marine Laboratory, UK to measure L(sub wn) in the western English Channel. Tests indicate that the buoy is capable of measuring spectral incident irradiance with less than 10% error and water-leaving radiance with less than 20% error; these errors are reduced by averaging and show no bias. There were 24 match-ups with good quality SeaWiFS data at the buoy site during the ten months of deployment within the period May 1997 and September 1998. The differences between the buoy and SeaWiFS measurements of L(sub wn) were found to be variable and often large. The root-mean-square (RMS) differences varied from 102% at 412 nm to 50% at 555 nm. The RMS differences in measurements of L(sub wn) could be reduced to less than 18% by a combination of increasing the calibration coefficients of SeaWiFS by between 0.2 and 4.3% in the visible bands and by tuning the extrapolation of aerosol radiances from the near infrared to the visible wavelengths. These results imply that the monitoring of the absolute calibration of the SeaWiFS bands is imperfect and errors remain in the extrapolation of aerosol radiances for atmospheric correction.

    We present the first results from a densely instrumented mooring array upstream of the Denmark Strait sill, extending from the Iceland shelfbreak to the Greenland shelf. The array was deployed from September 2011 to July 2012, and captured the vast majority of overflow water denser than 27.8 kg m-3 approaching the sill. The mean transport of overflow water over the length of the deployment was 3.54±0.16 Sv. Of this, 0.58 Sv originated from below sill depth, revealing that aspiration takes place in Denmark Strait. We confirm the presence of two main sources of overflow water: one approaching the sill in the East Greenland Current and the other via the North Icelandic Jet. Using an objective technique based on the hydrographic properties of the water, the transports of these two sources are found to be 2.54±0.17 Sv and 1.00±0.17 Sv, respectively. We further partition the East Greenland Current source into that carried by the shelfbreak jet (1.50±0.16 Sv) versus that transported by a separated branch of the current on the Iceland slope (1.04±0.15 Sv). Over the course of the year the total overflow transport is more consistent than the transport in either branch; compensation takes place among the pathways that maintains a stable total overflow transport. This is especially true for the two East Greenland Current branches whose transports vary out of phase with each other on weekly and longer time scales. We argue that wind forcing plays a role in this partitioning.

    Four moorings were deployed near "Dragon Flag," an active hydrothermal vent in the valley of the Southwest Indian Ridge. The goal was to examine the variability of currents and temperature, which will guide the trajectory of spreading plumes. The mean current was cross-isobath, and the circulation was characterized by a submesoscale circulation. Observed currents also showed fluctuations with periods of 1-15 days. The inferred phase speed and wavelength for the wave with a period of 4.4 day are 10.4 km d-1 and 45.8km, respectively, which are consistent with the topographic Rossby wave theory. The persistent warming tendency with corresponding variation of salinity based on background θ-S properties may be caused by background circulation and divergence of the water column. The warming or cooling episodes were most likely as signatures of isopycnal surface depression or uplifting induced by the moving of mesoscale eddies. Well-resolved rotary spectra exhibited important nonlinear interactions between inertial and semidiurnal tide in the velocity and temperature records. Amplification of near-inertial currents in the near bottom is also exposed. These discoveries provided new evidence for the nonlinear interaction and trapped near-inertial waves by the ridge, which occurred in the deep ocean of the Southern Hemisphere. Such nonlinear interaction may represent a significant energy loss pathway for the internal waves, and part of the decay of such motion would likely result in increased mixing to maintain the abyssal stratification. Enhanced near-inertial motions can play a major role for the local advection of hydrothermal plumes.

    Samples from a pristine raised peat bog runoff in Austria, the Tannermoor creek, were analysed for their iron linked to natural organic matter (NOM) content. Dissolved organic carbon < 0.45 μm (DOC) was 41-64 mg L(-1), iron 4.4-5.5 mg L(-1). Samples were analysed applying asymmetric field flow fractionation (AsFlFFF) coupled to UV-vis absorption, fluorescence and inductively coupled plasma mass spectrometry (ICP-MS). The samples showed an iron peak associated with the NOM peak, one sample exhibiting a second peak of iron independent from the NOM peak. As highland peat bogs with similar climatic conditions and vegetation to the Tanner Moor are found throughout the world, including areas adjacent to the sea, we examined the behaviour of NOM and iron in samples brought to euhaline (35‰) conditions with artificial sea salt. The enhanced ionic strength reduced NOM by 53% and iron by 82%. Size exclusion chromatography (SEC) of the samples at sea-like salinity revealed two major fractions of NOM associated with different iron concentrations. The larger one, eluting sharply after the upper exclusion limits of 4000-5000 g mol(-1), seems to be most important for iron chelating. The results outline the global importance of sub-mountainous and mountainous raised peat bogs as a source of iron chelators to the marine environment at sites where such peat bogs release their run-offs into the sea.

    The new European Competence Centre for Moor and Climate (EFMK) is an initiative by different local communities, environmental protection NGOs, agricultural services, and partners from the peat and other industries in Lower Saxony (Germany). The Centre aims to integrate practical peat bog conservation with a focus on green house gas emission after drainage and after water logging activities. Together with our partners we want to break new ground to protect the remaining bogs in the region. Sphagnum mosses will be produced in paludiculture on-site in cooperation with the local peat industry to provide economic and ecologic alternatives for peat products used in horticulture business. Land-use changes are needed in the region and will be stimulated in cooperation with agricultural services via compensation money transfers from environmental protection funds. On a global scale the ideas of Carbon Credit System have to be discussed to protect the peat bogs for climate protection issues. Environmental education is an important pillar of the EFMK. The local society is invited to explore the unique ecosystem and to participate in peat bog protection activities. Future generations will be taught to understand that the health of our peat bogs is interrelated with the health of the local and global climate. Besides extracurricular classes for schools the centre will provide infrastructure for Master and PhD students, as well for senior researchers for applied research in the surrounding moor. International partners in the scientific and practical fields of peat bog ecology, renaturation, green house gas emissions from peat bogs, and environmental policy are invited to participate in the European Competence Center for Moor and Climate.

    For detecting the seafloor crustal deformation and Tsunami associated with large earthquakes in real-time, it is necessary to monitor them just above the possible source region. For this purpose, we have been dedicated in developing a real-time continuous observation system using a multi-purpose moored buoy. Sea-trials of the system have been carried out near the Nanakai trough in 2013 and 2014 (Takahashi et al., 2014). We especially focused on the GPS/Acoustic measurement (GPS/A) in the system for horizontal crustal movement. The GPS/A on a moored buoy has a critical drawback compared to the traditional ones, in which the data can be stacked over ranging points fixed at an optimal position. Accuracy in positioning with a single ranging from an arbitrary point is the subject to be improved in this study. Here, we report the positioning results in the buoy system using data in the 2014 sea-trial and demonstrate the improvement of the result. We also address the potential resolving power in the positioning using synthetic tests. The target GPS/A site consists of six seafloor transponders (PXPs) forming a small inner- and a large outer-triangles. The bottom of the moored cable is anchored nearly the center of the triangles. In the sea-trial, 11 times successive ranging was scheduled once a week, and we plotted positioning results from different buoy position. We confirmed that scatter in positioning using six PXPs simultaneously is ten times smaller than that using individual triangle separately. Next, we modified the definition of the PXP array geometry using data obtained in a campaign observation. Definition of an array geometry is insensitive as far as ranging is made in the same position, however, severely affects the positioning when ranging is made from various positions like the moored buoy. The modified PXP array is slightly smaller and 2m deeper than the original one. We found that the scatter of positioning results in the sea-trial is reduced from 4m to 1

  17. Observing Coastal Upwelling Front Dynamics by AUV Tracking, Remote Sensing, and Mooring Measurements

    Coastal upwelling is a wind-driven ocean process that brings cooler, saltier, and usually nutrient-rich deep water upward to replace surface water displaced offshore due to Ekman transport. The nutrients carried up by upwelling are important for primary production and fisheries. The boundary between the stratified water column and the upwelling water column is called the "upwelling front". Upwelling fronts support enriched phytoplankton and zooplankton populations, thus having great influences on ocean ecosystems. Variations of wind and ocean circulation cause an upwelling front to move. In particular, as the upwelling favorable wind weakens, upwelling enters the relaxation phase. Frontal dynamics in this phase is not well understood. Satellite sea surface temperature (SST) images can show evolutions of upwelling fronts, but only their surface expressions. To enable in situ high-resolution tracking of upwelling frontal dynamics, we have developed a method for an autonomous underwater vehicle (AUV) to autonomously detect and track an upwelling front over a long duration. During the June 2012 CANON (Controlled, Agile, and Novel Observing Network) field program, the Tethys long-range AUV ran our algorithm to closely track an upwelling front in northern Monterey Bay over four days. The AUV tracking captured the front's westward movement. A series of satellite SST images show that the stratified water in the upwelling shadow (residing in the northeastern corner of the Bay) was transported westward, thus pushing the upwelling front westward. The westward movement of the upwelling filament followed weakening of the northwesterly wind (i.e., upwelling favorable wind). The AUV observations offered a window into frontal dynamics in the relaxation phase of the upwelling process. Temperature, salinity, and current velocity profiles measured at the MBARI M1 mooring (to the south of the AUV tracking line) showed that the westward frontal movement coincided with intrusion of

    The number and taxonomic structure of the heterotrophic block of aerobic and facultative anaerobic bacteria were studied in monoliths from a high-moor peat (stored at room temperature and in a refrigerator) and in the peat horizons mixed in laboratory vessels. The monitoring lasted for a year. In the T0 horizon, spirilla predominated at room and low temperatures; in the T1 and T2 horizons, bacilli were the dominants. The continuous mixing of the peat layers increased the oxygen concentration and the peat decomposition; hence, the shares of actinomycetes and bacilli (bacteria of the hydrolytic complex) increased. In the peat studied, the bacilli were in the active state; i.e., vegetative cells predominated, whose amount ranged from 65 to 90%. The representatives of the main species of bacilli (the facultative anaerobic forms prevailed) hydrolyzed starch, pectin, and carboxymethylcellulose. Thus, precisely sporiferous bacteria can actively participate in the decomposition of plant polysaccharides in high-moor peat soils that are characterized by low temperatures and an oxygen deficit. The development of actinomycetes is inhibited by low temperatures; they can develop only under elevated temperature and better aeration.

    The offshore wind industry is rapidly maturing and is now expanding to more extreme environments in deeper water and farther from shore. To date fixed foundation types (i.e. monopoles, jackets) have been primarily used but become uneconomical in water depths greater than 50m. Floating foundations have more complex dynamics but at the moment no design has reached commercialization, although a number of devices are being tested at prototype stage. The development of concepts is carried out through physical model testing of scaled devices such that to better understand the dynamics of the system and validate numerical models. This paper investigates the testing of a scale model of a tension moored wind turbine at two different scales and in the presence and absence of a spring damper controlling its dynamic response. The models were tested under combined wave and wind thrust loading conditions. The analysis compares the motions of the platform at different scales and structural conditions through RAO, testing a mooring spring damper for load reductions.

    In the current context of the ocean deoxygenation, OMZs are known to play a key-role on the evolution of climate (greenhouse gases) and on the ecosystems and fisheries (nitrogen loss, respiratory barrier, sulfidic events) at both local and global scales. One of the objectives of the AMOP (Activities of research dedicated to the Minimum of Oxygen in the eastern Pacific) project is to document the mechanisms associated with the OMZ variability from hourly to decadal timescales. The hypothesis is that the variability scale ranges are different at the oxycline compared to the OMZ core, and directly impact the OMZ recycling behavior acting as either a preservation or remineralization layer. Results from a mooring deployment off Callao put in evidence three main time scales of OMZ variability- intra daily, intra monthly and intra seasonally. A coupled model ROM-BioEBUS configuration of the Peruvian OMZ shows there is a marked longitudinal variability in the characteristics of the oxygen spectrum, indicative of a strong influence of mesoscale activity in shaping the OMZ structure offshore. Mooring data highlight oxygenation events occurring near the oxycline rather than within the core, and inducing a shift of the OMZ regime from organic matter preservation towards remineralisation.

    The aim of this study is to characterise bottom currents and associated seafloor sediments at the Ría de Vigo, a 28 km long by 12 km wide funnel shaped coastal embayments at the NW coast of the Iberian Peninsula. The embayment is south-westerly oriented, against the general northerly trend of the main coast, and partially closed at its mouth by the Cies Islands. Forms a wide U-valley with central depths varying from 10 to 60 m. Hydrodynamics shows a semidiurnal mesotidal regime, negative estuarine circulation; and important south-western wave climate component, particularly in winter. Coarse sediments are mostly siliciclastic-bioclastic carbonates mixtures and are preferentially distributed at shallow depths parallel to the coast. Fine grained sediments mostly consist of mud and are preferentially distributed in the most internal parts and occupying the deep central parts of the embayment. The survey was carried mooring two stations at the inner and outer parts of the embayment, the later quite close to the southern mouth. In each station the current velocity and direction, salinity, temperature, turbidity, pressure and dissolved oxygen were measured near the bottom. The survey period covered two weeks, from June 28th till July 11th of 2005. Surficial sediment grain size was characterised in representative sediment samples from different points of the ría, including the stations sites, using box corers. The analyzed temperature and salinity data show an upwelling process, taking place since the third day on, registering low temperature values, about 13°C and high salinity values, about 36.5 ppt. During the non-upwelling period the bottom current direction in both stations was different, NE during the flood SW during the ebb, at the station 1 and eastwards during the flood and SW during the ebb at the station 2. But during the upwelling period was the same at both stations, NE-SW. At the same time the velocity during whole survey period was higher in the first

    Upwelling in the Northern Benguela is mainly driven by local winds but nutrient and oxygen conditions on the shelf are largely determined by the intrusion of South Atlantic Central Water (SACW) through the Angola-Benguela Front (ABF). The poleward spreading of tropical waters is related to the propagation of Kelvin and continental shelf waves originating from the Equatorial Atlantic and bending poleward at the African coast. The strength of this remote forcing is thought to be especially relevant to the interannual variability of the upwelling system. We test the hypothesis that the poleward spreading of tropical water is driven by the combined action of both I) coastally trapped waves of equatorial origin bringing tropical water to the ABF zone and II) locally forced waves generating the undercurrent which advects SACW onto the shelf. Signals of poleward propagating waves were found in satellite altimeter data up to 12°S. To detect the propagation of coastally trapped waves further south in-situ measurements have been conducted. Three hydrographic moorings equipped inter alia with ADCPs have been deployed and maintained within the framework of the projects GENUS, SACUS and PREFACE. For the first time, simultaneous current measurements on the Namibian shelf have been realized at three different positions. The moorings are located in the Cunene cell, the Northern Namibian cell and the Central Namibian cell. By means of a regional circulation model based on MOM the propagation of coastally trapped waves are investigated with high spatial and temporal resolution (about 8km along the Namibian coast, 2-hour averages). It has been demonstrated that modelled meridional transports correspond well with long term measurements obtained by a mooring off Walvis Bay. The power spectral density shows sharp peaks for the tidal and inertial frequencies. A large proportion of kinetic energy accounts for the sub-inertial frequency range. Meridional transport signals were found to

    Crude preparations of Stephania tetrandra S. MOORE (ST), a traditional herbal medicine, have been used safely for arthritis and silicosis in China. In this study, we demonstrated that ST in vitro protects red blood cells from 2,2-azo-bis (2-amidinopropane) dihydrochloride (AAPH)-induced hemolysis. The inhibitory effect was dose-dependent at concentrations of 10 to 1000 microg/ml. Moreover, tests were carried out to identify the main ingredient of ST that exerts a scavenging effect on free-radicals. Three representative alkaloids, tetrandrine, fangchinoline, and cyclanoline, isolated from ST, were found to have inhibitory activities against AAPH-induced lysis of red blood cells (RBC). Furthermore, the ingestion of 200 mg of ST extract was associated with a significant increase in free-radical scavenging effect of plasma in rats. These results suggest that ST as antioxidant inhibits AAPH-induced hemolysis of RBC both in vitro and in vivo. PMID:15802807

    Knowledge on the relative contribution of direct genetic, maternal and environmental effects to adaptive divergence is important for understanding the drivers of biological diversification. The moor frog (Rana arvalis) shows adaptive divergence in embryonic and larval fitness traits along an acidification gradient in south-western Sweden. To understand the quantitative genetic basis of this divergence, we performed reciprocal crosses between three divergent population pairs and reared embryos and larvae at acid and neutral pH in the laboratory. Divergence in embryonic acid tolerance (survival) was mainly determined by maternal effects, whereas the relative contributions of maternal, additive and nonadditive genetic effects in larval life-history traits differed between traits, population pairs and rearing environments. These results emphasize the need to investigate the quantitative genetic basis of adaptive divergence in multiple populations and traits, as well as different environments. We discuss the implications of our findings for maintenance of local adaptation in the context of migrant and hybrid fitness.

    We present excerpts from three archival ultra high-speed films on the function of the human larynx by Paul Moore, Ph. D. and Hans von Leden, M.D. The films received two awards for best scientific cinematography from two different international film festivals in Italy in 1957. These films present ultra high-speed cinematographic accounts on the workings of the human vocal folds during various phonatory and ventilatory activities. These films were captured at speeds of 2000 to 5000 frames-per-second via an ingeniously arranged laryngeal mirror viewing device. Such speeds were revolutionary six decades ago. Technology currently allows us to film laryngeal behavior at speeds of up to 16,000 frames-per-second using digital recordings. However, the ultra high-speed films by Paul and Hans remain a beacon for anyone sincerely interested in how the smallest instrument of sound production works, and how it is subjected to failure by intrinsic or extrinsic factors.

    Simulating the coupled motions of multiple bodies in the time domain is a complex problem because of the strong hydrodynamic interactions and coupled effect of various mechanical connectors. In this study, we investigate the hydrodynamic responses of three barges moored side-by-side in a floatover operation in the frequency and time domains. In the frequency domain, the damping lid method is adopted to improve the overestimated hydrodynamic coefficients calculated from conventional potential flow theory. A time-domain computing program based on potential flow theory and impulse theory is compiled for analyses that consider multibody hydrodynamic interactions and mechanical effects from lines and fenders. Correspondingly, an experiment is carried out for comparison with the numerical results. All statistics, time series, and power density spectra from decay and irregular wave tests are in a fairly good agreement.

    As part of the support activities for a deepwater development in the Gulf of Mexico, a moored ocean observing system (OOS) was deployed in a water depth of approximately 2500m, 300km south of the Louisiana Coast. From June 2007 to May 2009, the system comprised seven single point Aanderaa Recording Current Meters (RCM), deployed at 450m, 700m, 1,100m, 1,500m, 2,000m, 2,400m and 2,490m below surface, and an RDI 75kHz Longranger Acoustic Doppler Current Profiler (ADCP), deployed between 249 and 373m below surface in upward-looking mode. Since May 2009, the OOS was upgraded to a Wavescan Buoy based moored system including meteorological sensors for: atmospheric pressure, air temperature, wind speed and direction; directional waves sensor; a Doppler Current Sensor (DCS) at 1.5 m depth for surface currents; and two downward-looking ADCP's covering the upper 1,000m of the water column. This OOS has been operating without interruptions from 2007 to the present and has registered data associated with nine tropical storms, including the direct passage of Hurricane Ike, in September of 2008, and loop current events with speeds of up to 4 knots. It has provided one of the most comprehensive set of velocity observations in the Gulf of Mexico, especially, the near surface currents, during pre-storm conditions, response, and ocean relaxation following hurricanes/tropical storms. Based on these observations the upper ocean responses to the energy input from tropical storms are characterized in terms of the associated mixing processes and momentum balances.

    One of the biggest water resource of Slovenian capital is groundwater of Ljubljana moor (Ljubljansko barje) aquifer. Quantity and quality of groundwater in Ljubljana moor aquifer directly depend on precipitation, surface water and riparian ecosystems of the Moor and indirectly by groundwater recharge from higher-lying mountainous karstic areas of forests and grasslands. Maintaining high groundwater level of the Ljubljana moor not only sustain stable water balance of aquifer, but also its riparian and wetland character. It also inhibit larger subsidence of the terrain. The paper addresses the vulnerability of the Ljubljana moor water resources to climate and land use change and due to groundwater overdraft. The results should help in selecting suitable mitigation measures and management of the Ljubljana moor area. We analyze surface and groundwater flow characteristics of water recharge area of one water work on the Ljubljana moor (Brest) from the point of view of climate change, changes in land use and water pumping practices. The I\\vska River, a tributary to the Ljubljanica River, recharges the area in the gravel bar, which lies just below the hills. We use existing data of meteorological, hydrological and hydrogeological monitoring and simulate rainfall-runoff processes. We use a conceptual semi-distributed rainfall-runoff model HBV-Light and simulate hydrological characteristics of the Ljubljana Moor (groundwater level fluctuations and recharge, surface - groundwater interchange) with two hydrodynamic models, DHI MIKE FLOOD (surface flow, 2D simulation) and DHI MIKE SHE (groundwater flow). For a calibration of runoff model HBV Light and MIKE SHE we use measured daily discharge data of the river I\\vska (1970-2010) and groundwater level data along the river (2010-2013) respectively. In groundwater modelling, we include the data of water pumping. Daily precipitation and temperature for period 2020 - 2050 are from ESAMBLE project for two GCM climate scenarios. We

    Rising atmospheric carbon dioxide (CO2) and climate change are increasing ocean temperatures and affecting ocean chemistry (e.g., ocean acidification). Monitoring these important changes using ships and other platforms generates large amounts of data from heterogenous sources. Since its inception in 1993, when it became a member of the DOE/NOAA Ocean Carbon Science Team engaged in the World Ocean Circulation Experiment (WOCE), the CDIAC Ocean Carbon Data Management Project has been organizing, quality assuring, documenting, archiving and distributing ocean carbon-related data collected via a number of U.S. and international ocean-observing programs. CDIAC's ocean carbon data collection includes discrete and underway measurements from a variety of platforms (e.g., research ships, commercial ships, buoys) in all oceans from the surface to seafloor. One important project at CDIAC is the data management support for the Global CO2 Time-series and Moorings Project. This poster will describe the collaboration between NOAA/PMEL Mooring group and CDIAC in the data management and archival of a high-frequency atmospheric and seawater pCO2 data from 14 open ocean sites using moored autonomous systems.. Advancements in the ocean carbon observation network over the last decade, such as the development and deployment of Moored Autonomous pCO2 (MAPCO2) systems, have dramatically improved our ability to characterize ocean climate, sea-air gas exchange, and biogeochemical processes. The Moored Autonomous pCO2 (MAPCO2) system provides high-resolution surface seawater and atmospheric CO2 data that can help us understand inter-annual, seasonal, and sub-seasonal dynamics and provide constrains on the impact of short-term biogeochemical variability on CO2 fluxes. CDIAC NDP-092 provides a description of the data as well as the methods and data quality control involved in developing an open-ocean MAPCO2 data set including over 100,000 individual atmospheric and seawater pCO2 measurements

    Designing optimal observation networks in coastal oceans remains one of the major challenges towards the implementation of future efficient Integrated Ocean Observing Systems to monitor the coastal environment. In the Bay of Biscay and the English Channel, the diversity of involved processes (e.g. tidally-driven circulation, plume dynamics) requires to adapt observing systems to the specific targeted environments. Also important is the requirement for those systems to sustain coastal applications. Two observational network design experiments have been implemented for the spring season in two regions: the Loire River plume (northern part of the Bay of Biscay) and the Western English Channel. The method used to perform these experiments is based on the ArM (Array Modes) formalism using an ensemble-based approach without data assimilation. The first experiment in the Loire River plume aims to explore different possible glider endurance lines combined with a fixed mooring to monitor temperature and salinity. Main results show an expected improvement when combining glider and mooring observations. The experiment also highlights that the chosen transect (along-shore and North-South, cross-shore) does not significantly impact the efficiency of the network. Nevertheless, the classification from the method results in slightly better performances for along-shore and North-South sections. In the Western English Channel, a tidally-driven circulation system, added value of using a glider below FerryBox temperature and salinity measurements has been assessed. FerryBox systems are characterised by a high frequency sampling rate crossing the region 2 to 3 times a day. This efficient sampling, as well as the specific vertical hydrological structure (which is homogeneous in many sub-regions of the domain), explains the fact that the added value of an associated glider transect is not significant. These experiments combining existing and future observing systems, as well as numerical

    Sounds of seismic airguns were detected in two years of data collected from large, remote areas near the Mid-Atlantic Ridge (MAR) and the East Pacific Rise (EPR). From February 1999-February 2001, six autonomous hydrophones were moored near the MAR between 15-35 N and 33-50 W, and six more were moored in the EPR between 8 N - 8 S and 95-110 W. Continuous acoustic data recovered from both arrays were examined for sounds associated with seismic airgun activity. This was done using an automatic detection algorithm designed to identify repetitive sounds in the 20-60 Hz band. Airgun impulses occurred every 10-20 s and were recorded frequently on all hydrophones. In the Atlantic, airgun activity peaked in the summer months, and airgun impulses were detected in nearly 100% of the hours examined; Pacific seasonal trends were less obvious. Because of the high source level of the airgun signals, it was possible to estimate the locations of ships conducting seismic surveys despite their great distance, often over 3,000 km from our array. In the Atlantic, we located seismic vessels, presumably commercial, working off the coast of Nova Scotia during summer, and off western Africa and northeast Brazil in spring, summer,and fall. During summer 1999, research airguns were recorded on the MAR near 26 N 50 W. In the eastern tropical Pacific, the predominant source of airgun sounds was seismic vessels in the nearshore waters of southern Ecuador and northern Peru. All of the areas in which intense airgun activity was detected include important habitat for marine mammals; one area included habitat of the critically endangered northern right whale. Sounds from airguns appear to be a major contributor to the sound field in the Atlantic and parts of the Pacific Ocean, and may be of concern given the recent interest in ocean noise and its effects on marine mammals. Acoustic pressure levels of earthquakes are also investigated, and received levels in some common marine mammal habitats are

    Conspicuous male colouration is expected to have evolved primarily through selection by female choice. In what way conspicuous colours could be advantageous to males scrambling for mates remains largely unknown. The moor frog (Rana arvalis) belongs to the so-called explosive breeders in which spawning period is short; intrasexual competition is strong, and males actively search and scramble for females. During breeding, male body colouration changes from a dull brown (similar to females) to a conspicuous blue, and we wanted to test if male blueness influences mating success or facilitates male mate recognition. To do so, we first measured the colour of mated and non-mated males using a spectrophotometer. In an experiment, we then analysed interactions of actual male moor frogs in natural spawning aggregations with a brown (resembling a female or a non-breeding male) and a blue model frog. Mated and non-mated males did not differ in colouration, suggesting that female choice based on colour traits was unlikely. In our behavioural experiment, male moor frogs spent significantly more time in contact and in amplexus with the brown model than with the blue model. Our results suggest that the nuptial colouration in moor frogs can act as a new type of visual signal in anurans evolved to promote instantaneous mate recognition allowing males to quickly move between rivals while scrambling for females.

    A simple and selective method was developed for the simultaneous determination of tetrandrine and fangchinoline in herbal medicine by HPLC with electrochemical detection (ECD) on a bare glassy carbon electrode. The HPLC separation and ECD conditions have been optimized. The separation was carried out on a WondaSil C18-WR column (4.6 mm × 250 mm, 5 μm), with the mobile phase of acetonitrile-ammonium acetate buffer (pH 6.5; 40 mM) (32:68, v/v) using an isocratic elution at the flow rate of 0.5 mL/min. The electrochemical detection potential was set at +0.9 V. The obtained LODs for tetrandrine and fangchinoline were 0.26 and 0.27 μmol/L, respectively. The method was successfully applied to the analysis of tetrandrine and fangchinoline contents in Stephania tetrandra S. Moore. It has been demonstrated that the LC-ECD method is an excellent technique for analysis of the herbal medicine. The mean recoveries were in the range of 95-105%, while the precision expressed as repetition of peak area was lower than 2.7%. PMID:22196802

    Drypetes gossweilleri S. Moore is a plant used in traditional medicine in Cameroon. The antifungal properties of its stem-bark crude extract and fractions DG(1), DG(2), DG(3), DG(4), DG(5), DG(6), DG(7), DG(8) and DG(9) were assayed by agar and broth dilution methods on solid and liquid media against C. Krusei, C. albicans, C. glabrata, T. mentagerophytes, M. langeroinii, M. gypeum, M. audouini, T. rubrum, T. soudanense, T. terrestre, A. flavus and A. niger. The results revealed a substantial antifungal effect with minimal inhibitory concentrations ranging respectively from 24.11µg/ml to 1562µg/ml for yeasts and from 3125µg/ml to 12500µg/ml for filamentous fungi. Among the fractions, fraction DG4 exerted the highest antifungal activity. Moreover, no toxic effect was noticed in male and female albinos Wistar rats treated per os with the crude stem bark's extract of Drypetes gossweileri at a dose up to 12g/kg of body weight. The phytochemical screening of the crude extract and fractions showed the presence of alkaloids, phenols, flavonoids, saponins, anthocyanines, anthraquinones, sterols, lipids and essential oils. Therefore, Drypetes gossweileri may be safe as phytomedecine for the treatment of fungal infections. PMID:22468013

    In 1965, Gordon Moore predicted a decade of exponential growth in the transistor density growth (and hence computing power) for integrated circuits that--with some modification--has held to the present day. In this talk, we discuss to what extent clean energy technologies are subject to similar laws of long term exponential improvement and how these improvement rates may be accelerating due to recent developments. We review a range of long term energy efficiency and technology productivity improvement trends ranging from lighting, televisions, refrigerators, HVAC, batteries, motors, power electronics and solar PV. After reviewing historical and recent trends, we discuss several factors that may lead to an acceleration of improvement rates in the clean energy technology sector. Finally, we discuss the Baumol effect which predicts how differential trends in technology productivity may affect trends in relative prices in the economy. We conclude with a discussion of some of the implications that Baumol's theories may have for the development of extreme levels of energy efficiency in the coming decades.

    1985-01-18

    A 1-year time series of volume transport through the Florida Straits near 27 degrees N was derived from an array of five subsurface current meter moorings. The transport estimates, determined on the basis of constant shear extrapolation of the subsurface velocities to the surface, are in good agreement with transports derived from submarine cable and Pegasus measurements. The annual transport cycle in 1982-1983 is complicated by large-amplitude fluctuations on time scales of 1 to 3 weeks, but it does exhibit a transport maximum in summer and a minimum in fall-winter, consistent with historical results and of similar magnitude. The energy density spectrum of transports is continuous with a slope of about -1.5 and does not show a gap between the periods of weeks and seasonal. Evidence was found for atmospheric forcing of transport fluctuations, with highest coherence between transport and the local meridional wind stress at periods of 10 and 15 days during the summer and 5 and 40 days during the winter.

At two future neutrino telescope sites, off Sicily (I) and off Peloponessos (Gr), we deployed 2500-3000 m long mooring lines with oceanographic instrumentation. At about 150 m above the sea-floor, a glass sphere was mounted to each line holding two 3″-diameter photo-multiplier-tubes 'PMTs' in opposing directions for a first deep-sea test. Due to technical problems the background optical count rate could not be well established. Here, the focus is on the variations with time of bioluminescence bursts and their correlation with currents. Spectral analysis demonstrates that the PMT data best resemble those of horizontal currents (kinetic energy), significantly peaking at near-inertial, sub-inertial mesoscale and (Gr only) at tidal frequencies. Out-of-phase differences between signals from opposing PMTs in the same optical unit indicate impacts of bioluminescent organisms as a function of current direction, rather than a bacterial glow constant with time.

    Environmental change can simultaneously cause abiotic stress and alter biological communities, yet adaptation of natural populations to co-changing environmental factors is poorly understood. We studied adaptation to acid and predator stress in six moor frog (Rana arvalis) populations along an acidification gradient, where abundance of invertebrate predators increases with increasing acidity of R. arvalis breeding ponds. First, we quantified divergence among the populations in anti-predator traits (behaviour and morphology) at different rearing conditions in the laboratory (factorial combinations of acid or neutral pH and the presence or the absence of a caged predator). Second, we evaluated relative fitness (survival) of the populations by exposing tadpoles from the different rearing conditions to predation by free-ranging dragonfly larvae. We found that morphological defences (relative tail depth) as well as survival of tadpoles under predation increased with increasing pond acidity (under most experimental conditions). Tail depth and larval size mediated survival differences among populations, but the contribution of trait divergence to survival was strongly dependent on prior rearing conditions. Our results indicate that R. arvalis populations are adapted to the elevated predator pressure in acidified ponds and emphasize the importance of multifarious selection via both direct (here: pH) and indirect (here: predators) environmental changes.

    Moore v. Regents of the University of California was one of the first cases internationally that dealt with the patenting of human genetic material. The case is closely related to the development of medicine and of biotechnology applied to medicine. These developments require the utilisation of human body parts, both for experiments and for transplant, and present certain major medico-legal problems. However, the case did not produce conclusive decisions on the various key legal issues that it raised involved in biomedical research and the patenting of human genetic material. This article re-examines the case from an Indian and an international perspective. After a brief introduction in Part I, Part II of the article describes existing laws in various countries with respect to the patenting of human genetic material. Part III discusses legal regimes applicable in the context of biological materials. Part IV elaborates on the importance of the doctrine of informed consent in the context of biomedical research on human subjects. Part V discusses the significance of bioethics in research and the patenting of biotechnology, according to international law. Part VI concludes the article with an assertion of the urgent need for legislation in this area.

    Moored surface wind measurements were recorded along the Pacific equator at 140, 124, 110, and 95 deg W during portions of 1980-1985. Minimum record length is one year. The annual mean and monthly mean westward speeds at 110 deg W were about 1.5 m/s higher during the year preceding the 1982-1983 El Nino than in the year following this event. The annual cycle, which moved westward at about 0.8 m/s, consisted of weak westward and northward speeds in February-April and vice versa in September-October. The spectral slope between 5-day and 0.05-day periods was -1.5. The rms amplitude of the 95-percent statistically significant diurnal period oscillation was 0.3 m/s, and the meridional component was nearly twice as large as the zonal component. The diurnal period wave was coherent (at the 95-percent confidence level) between 95 and 124 deg W, with westward phase propagation of about 138 m/s. No statistically significant spectral peak was found in the 40- to 50-day intraseasonal period band. The surface zonal ocean current component, which reached approximately 0.5 and -0.5 m/s in April and October, respectively at 110 deg W, influenced the surface wind stress computed from the quadratic bulk aerodynamic formulation by 10-20 percent.

  5. An in situ evaluation of TOPEX/Poseidon altimetric measurements versus meaurements made by moorings and inverted echo sounders for sea surface height

    NASA Technical Reports Server (NTRS)

    1994-01-01

    The classical method of observing the sea surface height has been to make shipboard measurements of the vertical - density profile, and then calculating the surface height relative to a deeper reference surface. Two methods (a moored vertical string of instruments and an inverted echo sounder) were subsequently developed to obtain longer time in situ measurements. The first of these can be thought of as an extension of the discrete bottle hydrocast while the second integrates acoustically over the water column. One purpose of this note is to compare the result when coincidental observations are made by these two methods. This was done at two sites in the western tropical Pacific. Two inverted echo sounders were deployed alongside two enhanced TOGA-COARE moorings to be used in an in situ evaluation of TOPEX/Poseidon altimetric measurements of sea surface height. The mooring and inverted echo sounder data reproduced one another, at low frequency, with a correlation of 0.93 and 0.95 and the altimeter correlated with each of the above values ranging from 0.84 to 0.94. It is concluded that the altimetric measurements are statistically equivalent to the in situ measurements in the area of study.

    The ultimate goal of IVF is to achieve healthy, single, live births following each single-embryo transfer. A timeline for this eventuality has never been defined. National implantation rates from 2003-2010 provided by the Society for Assisted Reproductive Technologies (SART) in the USA were evaluated. Regression analysis was applied to the annual trends. A high correlation was noted showing a linear increase from year to year ranging between 0.3% and 1.5% when maternal age was not higher than 42. This relationship can be retrospectively applied to earlier SART data reports. This incline may be partly technology driven and resembles Moore's law, which describes annual improvements in microchip performance. Based on the assumption that technology will continue to drive progress, the length of time required to reach 100% implantation was calculated. The interval varied between 43 years (AD 2053) for the youngest age group (<35 years old) and 294 years for the 41-42-year age group. The timeframe is shifted for the younger patients to an earlier date of 2027 if a subset of clinics with high implantation regression slopes and low variance is selected. The implications of these findings for infertility treatment and fertility preservation are discussed. Success after IVF has steadily improved. Data from US-based clinics are annually collected by the Society for Assisted Reproductive Technologies (SART; www.sart.org). Through SART, individual clinic's outcomes may be assessed. Although live birth and pregnancy are considered the gold standard of success, the investigators took the approach that those outcomes are often biased due to transfer of multiple embryos. The present analysis was therefore performed on individual embryos, by using the implantation rate to compare national and individual clinic datasets. National implantation rates show a linear increase from year to year ranging between 0.3% and 1.5% for patients aged <43 years. We postulate that this linear trend

    Where peatlands are found in a degraded state it is often felt that interventions should be implemented to return these to a more 'natural state'. However there is a lack of long-term data from peatland restoration projects at scales greater than ditch network or hillslope scale. Within the UK significant investment has been made to block open-cut ditches in many upland blanket peatlands. It has been widely suggested that ditch blocking impacts both water quality and quantity. However, much of the work to understand these impacts has relied on studies focused at the ditch or slope scale. Stean Moor is drained heavily at 15.8 km of ditches per km2. In 2009 investment was secured to block these ditches, with c. 30000 peat dams being installed over winter 2009/10 and 2010/11. At twelve stream monitoring sites (11 affected by blocking upstream and 1 control) discharge and turbidity has been continuously monitored since 2009. Stream water sampling has also been undertaken monthly and through storm event sampling using autosamplers and tested for water colour, DOC and suspended sediment concentration (SSC). Overall there is a lack of significant changes to either discharge or water quality at the catchment scale. We suggest that drain blocking has not led to clear changes in streamflow hydrology due to i) two competing hydrological changes within the peatland cancelling each other out and ii) the severe nature of the peatland degradation at the site such that rapid recovery in some hydrological functions has not occurred. There has also been no rapid recovery (reduction) in aquatic carbon production due to the severe nature of the degradation caused by dense drainage and wider disturbances. In addition, wider degradation features such as some of the major sediment sources in the catchment were not dealt with by ditch blocking alone demonstrating that multiple interventions are required in some peatland systems to properly deal with site rehabilitation and ecosystem

    The common wisdom is that steady-state hilltops should display convex shape with both uniform soil thickness and uniform rates of lowering of the soil-bedrock interface. A 120 m hilltop transect on Bodmin Moor, southwest UK, displays a parabolic hilltop form, which implies it is in geomorphic steady state, yet the measured depths to bedrock range almost 6-fold from 14 to 80 cm, and the soil production rates derived from 10Be concentrations in rock at the soil interface range by 2-fold from 10 to 20 m/My. We address this conundrum by developing a theory to explain the scatter in soil depths that would result from block-by-block lowering of the soil-bedrock boundary, and support our theory with a simple model involving block release and diffusive transport. We show that over long timescales a hilltop can indeed be in geomorphic steady state while at any point in time exhibiting a broad range of depths to bedrock. Variable depth to bedrock results in variable 10Be concentrations in the rock sampled at the base of regolith, which yields calculated soil production rates that vary about the long-term average. Hence, scatter in plots of soil production as a function of soil depth are to be expected in many landscapes, and if the landscape is in geomorphic steady state, this scatter reflects the stochastic nature of the block release mechanism by which the bedrock interface is lowering. We find in our models that the commonly observed humped and exponentially declining soil production functions are only preserved during the transient approach toward geomorphic steady state.

  9. Reconstruction of a Tornado Disaster Employing Remote Sensing Techniques: A Case Study of the 1999 Moore, Oklahoma Tornado

    Wagner, Melissa A.

    Remote sensing has demonstrated to be an instrumental tool in monitoring land changes as a result of anthropogenic change or natural disasters. Most disaster studies have focused on large-scale events with few analyzing small-scale disasters such as tornadoes. These studies have only provided a damage assessment perspective with the continued need to assess reconstruction. This study attempts to fill that void by examining recovery from the 1999 Moore, Oklahoma Tornado utilizing Landsat TM and ETM+ imagery. Recovery was assessed for 2000, 2001 and 2002 using spectral enhancements (vegetative and urban indices and a combination of the two), a recovery index and different statistical thresholds. Classification accuracy assessments were performed to determine the precision of recovery and select the best results. This analysis proved that medium resolution imagery could be used in conjunction with geospatial techniques to capture recovery. The new indices, Shortwave Infrared Index (SWIRI) and Coupled Vegetation and Urban Index (CVUI), developed for disaster management, were the most effective at discerning reconstruction using the 1.5 standard deviation threshold. Recovery rates for F-scale damages revealed that the most incredibly damaged areas associated with an F5 rating were the slowest to recover, while the lesser damaged areas associated with F1-F3 ratings were the quickest to rebuild. These findings were consistent for 2000, 2001 and 2002 also exposing that complete recovery was never attained in any of the F-scale damage zones by 2002. This study illustrates the significance the biophysical impact has on recovery as well as the effectiveness of using medium resolution imagery such as Landsat in future research.

    Subduction is the mechanism by which water masses formed in the mixed layer and near the surface of the ocean find their way into the upper thermocline. The subduction process and its underlying mechanisms were studied through a combination of Eulerian and Langrangian measurements of velocity, measurements of tracer distributions and hydrographic properties and modeling. An array of five surface moorings carrying meteorological and oceanographic instrumentation were deployed for a period of two years beginning in June 1991 as part of an Office of Naval Research (ONR) funded Subduction experiment. Three eight month deployments were planned. The initial deployment of five surface moorings took place during the third leg of R/V Oceanus cruise number 240. The moorings were deployed at 18 deg N 34 deg W, 18 deg N 22 deg W, 25.5 deg N 29 deg W, 33 deg N 22 deg W and 33 deg N 34 deg W. A Vector Averaging Wind Recorder (VAWR) and an Improved Meteorological Recorder (IMET) collected wind speed and wind direction, sea surface temperature, air temperature, short wave radiation, barometric pressure and relative humidity. The IMET also measured precipitation. The moorings were heavily instrumented below the surface with Vector Measuring Current Meters (VMCM) and single point temperature recorders. Expendable bathythermograph (XBT) data were collected and meteorological observations were made while transitting between mooring locations. This report describes the work that took place during R/V Oceanus cruise 250 which was the second scheduled Subduction mooring cruise. During this cruise the first setting of the moorings were recovered and redeployed for a second eight month period.

    Changes of the Arctic Ocean environment are well known as one of the most remarkable evidences of global warming, attracting social and public attentions as well as scientists'. However, to illustrate on-going changes and predict future condition of the Arctic marine environment, we still do not have enough knowledge of Arctic sea ice and marine environment. In particular, lack of observation data in winter, e.g., under sea ice, still remains a key issue for precise understanding of seasonal cycle on oceanographic condition in the Arctic Ocean. Mooring-based observation is one of the most useful methods to collect year-long data in the Arctic Ocean. We have been conducting long-term monitoring using mooring system in the Pacific sector of the Arctic Ocean. Volume, heat, and freshwater fluxes through Barrow Canyon where is a major conduit of Pacific-origin water-masses into the Canada Basin have been observed since 2000. We show from an analysis of the mooring results that volume flux through Barrow Canyon was about 60 % of Bering Strait volume flux. Averaged heat flux ranges from 0.9 to 3.07 TW, which could melt 88,000 to 300,000 km2 of 1m thick ice in the Canada Basin, which likely contributed to sea ice retreat in the Pacific sector of the Arctic Ocean. In winter, we found inter-annual variability in salinity related to coastal polynya activity in the Chukchi Sea. In collaboration with Distributed Biological Observatory (DBO) project, which is one of the tasks of Sustaining Arctic Observing Network (SAON), we also initiated year-long mooring observation in the Hope Valley of the southern Chukchi Sea since 2012. Interestingly, winter oceanographic conditions in the Hope Valley are greatly different between in 2012-2013 and in 2013-2014. We speculate that differences of sea ice freeze-up and coastal polynya activity in the southern Chukchi Sea cause significant difference of winter oceanographic condition. It suggests that recent sea ice reduction in the Pacific

    A sediment trap moored in the naturally iron-fertilized Kerguelen Plateau in the Southern Ocean provided an annual record of particulate organic carbon and nitrogen fluxes at 289 m. At the trap deployment depth, current speeds were typically low (~ 10 cm s-1) and primarily tidal-driven (M2 tidal component). Although advection was weak, the sediment trap may have been subject to hydrodynamical and biological (swimmer feeding on trap funnel) biases. Particulate organic carbon (POC) flux was generally low (< 0.5 mmol m-2 d-1), although two episodic export events (< 14 days) of 1.5 mmol m-2 d-1 were recorded. These increases in flux occurred with a 1-month time lag from peaks in surface chlorophyll and together accounted for approximately 40% of the annual flux budget. The annual POC flux of 98.2 ± 4.4 mmol m-2 yr-1 was low considering the shallow deployment depth but comparable to independent estimates made at similar depths (~ 300 m) over the plateau, and to deep-ocean (> 2 km) fluxes measured from similarly productive iron-fertilized blooms. Although undertrapping cannot be excluded in shallow moored sediment trap deployment, we hypothesize that grazing pressure, including mesozooplankton and mesopelagic fishes, may be responsible for the low POC flux beneath the base of the winter mixed layer. The importance of plankton community structure in controlling the temporal variability of export fluxes is addressed in a companion paper.

  14. Automatic recognition of T and teleseismic P waves by statistical analysis of their spectra: An application to continuous records of moored hydrophones

    A network of moored hydrophones is an effective way of monitoring seismicity of oceanic ridges since it allows detection and localization of underwater events by recording generated T waves. The high cost of ship time necessitates long periods (normally a year) of autonomous functioning of the hydrophones, which results in very large data sets. The preliminary but indispensable part of the data analysis consists of identifying all T wave signals. This process is extremely time consuming if it is done by a human operator who visually examines the entire database. We propose a new method for automatic signal discrimination based on the Gradient Boosted Decision Trees technique that uses the distribution of signal spectral power among different frequency bands as the discriminating characteristic. We have applied this method to automatically identify the types of acoustic signals in data collected by two moored hydrophones in the North Atlantic. We show that the method is capable of efficiently resolving the signals of seismic origin with a small percentage of wrong identifications and missed events: 1.2% and 0.5% for T waves and 14.5% and 2.8% for teleseismic P waves, respectively. In addition, good identification rates for signals of other types (iceberg and ship generated) are obtained. Our results indicate that the method can be successfully applied to automate the analysis of other (not necessarily acoustic) databases provided that enough information is available to describe statistical properties of the signals to be identified.

    In a previous article, Moore, Rosenberg and Coleman (Brain and Language, 2005, 94, 72-85) reported evidence for significant improvements in phonological awareness in mainstream children following 6 h of exposure to a commercially available phoneme discrimination training programme, but not in a control group. In a follow-up study, we failed to replicate this finding, despite using an almost identical training programme (Halliday, Taylor, Millward, & Moore, Journal of Speech, Language, and Hearing Research, 2012, 55, 168-181). This paper directly compares the methods and the results of the two studies, in an effort to explain the discrepant findings. It reports that the trained group in Moore et al. (2005) showed significantly greater improvements in phonological awareness following training than the trained group in Halliday et al. (2012). However, the control group in Halliday et al. (2012) showed significantly greater improvements in phonological awareness than the control group in Moore et al. (2005). The paper concludes that differences in the randomization, blinding, experimenter familiarity and treatment of trained and control groups contributed to the different outcomes of the two studies. The results indicate that a plethora of factors can contribute to training effects and highlight the importance of well-designed randomized controlled trials in assessing the efficacy of a given intervention. © 2014 The Authors.

    The Vermejo-Moore Hooper field lies in the deep Delaware basin adjacent to the Pecos River in Loving and Ward counties, Texas. Discovered in 1973, the field produces dry gas from the Fusselman and Ellenburger formations. The Fusselman reservoir has produced over 400 bcf of gas from depths between 18,500 and 19,200 ft. The field primarily is a structural trap, but the distribution of reserves in the reservoir suggests a strong stratigraphic component. The reservoir is composed of fractured dolomites and cherts of the Silurian Fusselman and overlying Wristen formations. Unconformities and their accompanying diagenetic processes play a major role in the reservoir. The occurrence of pervasive dolomitization and nodular cherts are interpreted to indicate diagenesis associated with subaerial exposure and karsting. Thick sections also may be absent due to erosion over paleostructures, and preserved in flanking positions. Detailed paleostructural interpretation of the Vermejo-Moore Hooper field reveals a history of recurrent movement of the basement and demonstrates the influence of structural growth on the development and distribution of porosity and permeability in the Fusselman reservoir. Early structural growth can influence the distribution of both depositional facies and erosional processes. Paleostructure maps in the Silurian-Devonian indicate that a series of northwest-southeast-trending, low-relief structures existed during the Silurian. Growth of these structures through the Devonian can be documented and the presence of fault-bounded basement blocks can be inferred. The influence of this structural growth on the development of the reservoir is also demonstrated.

  19. Impact of recirculation on the East Greenland Current in Fram Strait: Results from moored current meter measurements between 1997 and 2009

    Transports of total volume and water masses obtained from a mooring array in the East Greenland Current (EGC) in Fram Strait are presented for the period 1997-2009. The array in the EGC was moved along isobaths from 79°N to 78°50‧N in 2002 to line up with moorings in the eastern Fram Strait. Analysis of the time series at the two latitudes shows that associated with the southward move, the annual mean volume transport of the EGC increased from 5.8±1.8 Sv to 8.7±2.5 Sv, mostly related with an increase in barotropic flow. This suggests a recirculation of close to 3 Sv at 78°50‧N as a consequence of the large-scale wind-driven cyclonic gyre in the Nordic Seas. In addition, the volume transport at 78°50‧N showed a clear seasonal cycle which was absent at 79°N. Estimates of the wind-driven Sverdrup transport at two different latitudes show that the difference in total volume transport and seasonality can largely be explained by the wind-stress curl. However, weak transport in 2003 was only partially related with weak Sverdrup transport and coincided also with anomalously weak northerly winds. The stronger recirculation at 78°50‧N has also consequences for the observed Atlantic Water: there is significantly more Atlantic derived water present at the southerly latitude. In addition, the warm anomaly in Fram Strait between 2005 and 2007 doubled the amount of Recirculated Atlantic Water temporarily. Finally, we estimate that close to 2.7 Sv, or 50%, of Atlantic derived water recirculates in Fram Strait.

    Year-long (summer 1995 to 1996) time series of temperature, salinity and current velocity from three slope sites spanning the junction of the Lomonosov Ridge with the Eurasian continent are used to quantify the water properties, transformations and transport of the boundary current of the Arctic Ocean. The mean flow is cyclonic, weak (1 to 5 cm s -1), predominantly aligned along isobaths and has an equivalent barotropic structure in the vertical. We estimate the transport of the boundary current in the Eurasian Basin to be 5±1 Sv. About half of this flow is diverted north along the Eurasian Basin side of the Lomonosov Ridge. The warm waters (>1.4°C) of the Atlantic layer are also found on the Canadian Basin side of the ridge south of 86.5°N, but not north of this latitude. This suggests that the Atlantic layer crosses the ridge at various latitudes south of 86.5°N and flows southward along the Canadian Basin side of the ridge. Temperature and salinity records indicate a small (0.02 Sv), episodic flow of Canadian Basin deep water into the Eurasian Basin at ˜1700 m, providing a possible source for an anomalous eddy observed in the Amundsen Basin in 1996. There is also a similar flow of Eurasian Basin deep water into the Canadian Basin. Both flows probably pass through a gap in the Lomonosov Ridge at 80.4°N. A cooling and freshening of the Atlantic layer, observed at all three moorings, is attributed to changes (in temperature and salinity and/or volume) in the outflow from the Barents Sea the previous winter, possibly caused by an observed increased flow of ice from the Arctic Ocean into the Barents Sea. The change in water properties, which advects at ˜5 cm s -1 along the southern edge of the Eurasian Basin, also strengthens the cold halocline layer and increases the stability of the upper ocean. This suggests a feedback in which ice exported from the Arctic Ocean into the Barents Sea promotes ice growth elsewhere in the Arctic Ocean. The strongest currents

    Foragers must often travel from a central place to exploit aggregations of prey. These patches can be identified behaviorally when a forager shifts from travel to area restricted search, identified by a decrease in speed and an increase in sinuosity of movement. Faster, more directed movement is associated with travel. Differentiating foraging behavior at patches from travel to patches is important for a variety of research questions and has now been made easier by the advent of small, GPS devices that can track forager movement with high resolution. In the summer and fall of 2012, movement data were collected from GPS devices placed on foraging trips originating in the artisanal fishing village of Desa Ikan (pseudonym), on the east coast of the Caribbean island nation of the Commonwealth Dominica. Moored FADs are human-made structures anchored to the ocean floor with fish attraction material on or near the surface designed to effectively create a resource patch. The ultimate goal of the research is to understand how property rights are emerging after the introduction of fish aggregating device (FAD) technology at the site in 1999. This paper reports on research to identify area-restricted search foraging behavior at FAD patches. For 22 foraging trips simultaneous behavioral observations were made to ground-truth the GPS movement data. Using a cumulative sum method, area restricted search was identified as negative deviations from the mean travel speed and the method was able to correctly identify FAD patches in every case.

    Major changes in salinity (approx.14 ppt.) and temperature (approx.40C) were continuously registered by two prototype NASA DRIFTERs, surface moored floaters, that NASA's Applied Science and Technology Project Office (ASTPO) has developed. The DRIFTER floating sensor module is equipped with an Arduino open-source electronics prototyping platform and programming language (http://www.arduino.cc), a GPS (Global Positioning System) module with antenna, a cell phone SIM (Subscriber Identity Module) card and a cellular antenna which is used to transmit data, and a probe to measure temperature and conductivity (from which salinity can be derived). The DRIFTER is powered by a solar cell panel and all the electronic components are mounted and sealed in [ waterproof encasement. Position and measurement data are transmitted via short message service (SMS) messaging to a Twitter site (DRIFTER 002@NASADRIFTER_002 and DRIFTER 004@NASADRIFTER_004), which provides a live feed. These data are the imported into a Google spreadsheet where conductivity is converted to salinity, and graphed in real-time. The spreadsheet data will be imported into a webpage maintained by ASTPO, where it will be displayed available for dO\\\\1lload.

    In response to an increasing demand for operational tools that benefit both efficiency and environmental compliance, General Physics Corporation (GP) has developed and installed a unique aid to optimize sootblowing at Delmarva Power`s Edge Moor Unit No. 5. By combining expert system techniques with a rigorous mathematical model, a robust and reliable indication of boiler section(s) cleanliness is graphically presented to the control room operators on a minute-to-minute basis. The overall approach used in the heat transfer model is based upon technology developed in the former Soviet Union while the expert system component acts as an independent {open_quotes}cross-check{close_quotes} of the values calculated in the math model. This paper presents an overview of the general engineering approach used in developing the boiler cleanliness module as an integral part of a power plant`s, performance monitoring system. It includes graphical displays of the user interface and describes the concepts behind the heat transfer model as well as typical expert system rules used to verify the accuracy of the model. The paper concludes with {open_quotes}lessons learned{close_quotes} and a comparison of empirical data versus calculated cleanliness values for the various boiler sections over a wide capacity range of the boiler.

    Microevolutionary responses to spatial variation in the environment seem ubiquitous, but the relative role of selection and neutral processes in driving phenotypic diversification remain often unknown. The moor frog (Rana arvalis) shows strong phenotypic divergence along an acidification gradient in Sweden. We here used correlations among population pairwise estimates of quantitative trait (P(ST) or Q(ST) from common garden estimates of embryonic acid tolerance and larval life-history traits) and neutral genetic divergence (F(ST) from neutral microsatellite markers), as well as environmental differences (pond pH, predator density, and latitude), to test whether this phenotypic divergence is more likely due to divergent selection or neutral processes. We found that trait divergence was more strongly correlated with environmental differences than the neutral marker divergence, suggesting that divergent natural selection has driven phenotypic divergence along the acidification gradient. Moreover, pairwise P(ST) s of embryonic acid tolerance and Q(ST) s of metamorphic size were strongly correlated with breeding pond pH, whereas pairwise Q(ST) s of larval period and growth rate were more strongly correlated with geographic distance/latitude and predator density, respectively. We suggest that incorporating measurements of environmental variation into Q(ST) -F(ST) studies can improve our inferential power about the agents of natural selection in natural populations.

  6. Calculating IP Tuning Knobs for the PEP II High Energy Ring using Singular Value Decomposition, Response Matrices and an Adapted Moore Penrose Method

    The PEP II lattices are unique in their detector solenoid field compensation scheme by utilizing a set of skew quadrupoles in the IR region and the adjacent arcs left and right of the IP. Additionally, the design orbit through this region is nonzero. This combined with the strong local coupling wave makes it very difficult to calculate IP tuning knobs which are orthogonal and closed. The usual approach results either in non-closure, not being orthogonal or the change in magnet strength being too big. To find a solution, the set of tuning quads had to be extended which resulted having more degrees of freedom than constraints. To find the optimal set of quadrupoles which creates a linear, orthogonal and closed knob and simultaneously minimizing the changes in magnet strength, the method using Singular Value Decomposition, Response Matrices and an Adapted Moore Penrose method had to be extended. The results of these simulations are discussed below and the results of first implementation in the machine are shown.

    Seasonal variability of diatom abundance and species composition in sinking particles in the northern South China Sea was studied using continuous time-series sediment trap moorings during a one-year period, 2009-2010. A clear seasonal pattern of diatom abundance was observed, with higher fluxes in winter than in summer. This could be related to positive response of diatom growth to increased nutrient supply from the subsurface waters as a result of enhanced vertical mixing in winter. Mesoscale eddy activities and strong Asian dust input could also stimulate the diatom growth and increase the diatom export flux to the deep South China Sea. The strong Asian dust input during spring 2010 probably accelerated the aggregation and downward flux of diatoms in the northern South China Sea. No distinctive seasonal pattern in diatom species composition was recorded, but there was a close correlation of diatom abundances with the cell size and the degree of silification. The sinking velocity of the diatom related particles from the sea surface to the deep South China Sea has been estimated to be ~30-50 m d-1 by comparing the surface chlorophyll a with the diatom abundance and species in sediment traps at 1003 m and 3226 m depths. Strong dissolution of small-sized and low-silicified diatom species and lateral advection of particles were also indicated for the deep northern South China Sea. The present results are crucial as a basis for future understanding of fossil assemblage changes in connection with palaeoclimatic and palaeooceanographic research.

    Background A decoction of Crassocephallum vitellinum (Benth.) S. Moore (Asteraceae) is used in Kagera Region to treat peptic ulcers. This study seeks to evaluate an aqueous ethanol extract of aerial parts of the plant for safety and efficacy. Methods An 80% ethanolic extract of C. vitellinum at doses of 100, 200, 400 and 800 mg/kg body wt was evaluated for ability to protect Sprague Dawley rats from acidified ethanol gastric ulceration in comparison with 40 mg/kg body wt pantoprazole. The extract and its dichloromethane, ethyl acetate, and aqueous fractions were also evaluated for acute toxicity in mice, brine shrimp toxicity, and antibacterial activity against four Gram negative bacteria; Escherichia coli (ATCC 25922), Salmonella typhi (NCTC 8385), Vibrio cholera (clinical isolate), and Streptococcus faecalis (clinical isolate). The groups of phytochemicals present in the extract were also determined. Results The ethanolic extract of C. vitellinum dose-dependently protected rat gastric mucosa against ethanol/HCl insult to a maximum of 88.3% at 800 mg/kg body wt, affording the same level of protection as by 40 mg/kg body wt pantoprazole. The extract also exhibited weak antibacterial activity against S. typhi and E. coli, while its ethyl acetate, dichloromethane and aqueous fractions showed weak activity against K. pneumonia, S.typhi, E. coli and V. cholera. The extract was non-toxic to mice up to 5000 mg/kg body wt, and the total extract (LC50 = 37.49 μg/ml) and the aqueous (LC50 = 87.92 μg/ml), ethyl acetate (LC50 = 119.45 μg/ml) and dichloromethane fractions (88.79 μg/ml) showed low toxicity against brine shrimps. Phytochemical screening showed that the extract contains tannins, saponins, flavonoids, and terpenoids. Conclusion The results support the claims by traditional healers that a decoction of C.vitellinum has antiulcer activity. The mechanism of cytoprotection is yet to be determined but the phenolic compounds present in the

  9. Influence of salinity on the interannual heat storage trends in the Atlantic estimated from altimeters and Pilot Research Moored Array in the Tropical Atlantic data

    Changes in the oceanic heat storage (HS) can reveal important evidences of climate variability related to ocean heat fluxes. Specifically, long-term variations in HS are a powerful indicator of climate change as HS represents the balance between the net surface energy flux and the poleward heat transported by the ocean currents. HS is estimated from sea surface height anomaly measured from the altimeters TOPEX/Poseidon and Jason 1 from 1993 to 2006. To characterize and validate the altimeter-based HS in the Atlantic, we used the data from the Pilot Research Moored Array in the Tropical Atlantic (PIRATA) array. Correlations and rms differences are used as statistical figures of merit to compare the HS estimates. The correlations range from 0.50 to 0.87 in the buoys located at the equator and at the southern part of the array. In that region the rms differences range between 0.40 and 0.51 × 109 Jm-2. These results are encouraging and indicate that the altimeter has the precision necessary to capture the interannual trends in HS in the Atlantic. Albeit relatively small, salinity changes can also have an effect on the sea surface height anomaly. To account for this effect, NCEP/GODAS reanalysis data are used to estimate the haline contraction. To understand which dynamical processes are involved in the HS variability, the total signal is decomposed into nonpropagating basin-scale and seasonal (HSl) planetary waves, mesoscale eddies, and small-scale residual components. In general, HSl is the dominant signal in the tropical region. Results show a warming trend of HSl in the past 13 years almost all over the Atlantic basin with the most prominent slopes found at high latitudes. Positive interannual trends are found in the halosteric component at high latitudes of the South Atlantic and near the Labrador Sea. This could be an indication that the salinity anomaly increased in the upper layers during this period. The dynamics of the South Atlantic subtropical gyre could

    2012-01-01

    Digital flood-inundation maps for a 5.5-mile reach of the Peachtree Creek from the Norfolk Southern Railway bridge to the Moores Mill Road NW bridge, were developed by the U.S. Geological Survey (USGS) in cooperation with the City of Atlanta, Georgia. The inundation maps, which can be accessed through the USGS Flood Inundation Mapping Science Web site at http://water.usgs.gov/osw/flood_inundation/, depict estimates of the areal extent and depth of flooding corresponding to selected water levels (stages) at the USGS streamgage at Peachtree Creek at Atlanta, Georgia (02336300) and the USGS streamgage at Chattahoochee River at Georgia 280, near Atlanta, Georgia (02336490). Current water level (stage) at these USGS streamgages may be obtained at http://waterdata.usgs.gov/ and can be used in conjunction with these maps to estimate near real-time areas of inundation. The National Weather Service (NWS) is incorporating results from this study into the Advanced Hydrologic Prediction Service (AHPS) flood warning system (http:/water.weather.gov/ahps/). The NWS forecasts flood hydrographs at many places that commonly are collocated at USGS streamgages. The forecasted peak-stage information for the USGS streamgage at Peachtree Creek, which is available through the AHPS Web site, may be used in conjunction with the maps developed in this study to show predicted areas of flood inundation. A one-dimensional step-backwater model was developed using the U.S. Army Corps of Engineers HEC–RAS software for a 6.5-mile reach of Peachtree Creek and was used to compute flood profiles for a 5.5-mile reach of the creek. The model was calibrated using the most current stage-discharge relations at the Peachtree Creek at Atlanta, Georgia, streamgage (02336300), and the Chattahoochee River at Georgia 280, near Atlanta, Georgia, streamgage (02336490) as well as high water marks collected during the 2010 annual peak flow event. The hydraulic model was then used to determine 50 water

    A reversed phase high performance liquid chromatography (RP-HPLC) method for simultaneous determination of fangchinoline (FAN) and tetrandrine (TET) in Stephania tetrandra S. Moore was established by using 1-hexyl-3-methylimidazolium tetrafluoroborate as the mobile phase additives in this paper. Four types of 1-alkyl-3-methylimidazolium-based ionic liquids (ILs) were used as additives of the mobile phase to separate FAN and TET by RP-HPLC. The effects of the length of the alkyl group on the imidazolium ring and its counterion, the concentrations of IL and the pH of the mobile phase, which influenced the chromatographic behaviors of FAN and TET, were investigated in detail. The linearity, sensitivity, accuracy and repeatability of the proposed method were also investigated. The probable mechanism of the separation with ILs as the mobile phase additives was explored and discussed. PMID:23452799

    This paper investigated metal contamination in muscle tissue of the grouper (Epinephelus coioides) in the vicinity of a single buoy mooring (SBM3) at the Sultanate of Oman. The fish samples were analyzed for cadmium (Cd), copper (Cu), lead (Pb) and vanadium (V). The mean concentrations of Cd, Cu, Pb and V in the fish samples were 0.05 ± 0.004, 0.34 ± 0.013, 0.20 ± 0.018 and 0.03 ± 0.006 mg/kg, respectively. The results were compared with the corresponding permissible concentration limits according to the Sultanate of Oman (0.05, 3.28, 0.3 and 1.4 mg/kg for Cd, Cu, Pb and V, respectively) and the European Commission (0.05 mg/kg for Cd and 0.3 mg/kg for Pb). It was found that none of the overall mean metal concentrations exceeded the corresponding Omani legislation or European Commission limits. However, the overall mean concentration of Cd was identical to the maximum permissible limit of 0.05 mg/kg that has been established by both Commissions, and the limits were exceeded for mean Cd levels in fish at two of the six sampling stations at SBM3. In general, this study indicated that the fishes at SBM3 were not highly contaminated with these metals.

    A rapid, sensitive, and reliable analytical method based on ultra high performance liquid chromatography with tandem mass spectrometry has been developed for the simultaneous determination of fangchinoline and tetrandrine in rat plasma. Plasma samples were pretreated by protein precipitation with acetonitrile. The analysis was performed on a C18 reversed-phase ultra high performance liquid chromatography column (2.1 mm × 100 mm, 3.5 μm, Agilent), and the flow rate was set at 0.4 mL/min. Under the experimental conditions, extraction recoveries from plasma were 68.1-72.8% for fangchinoline and 69.2-76.5% for tetrandrine. The plasma concentrations of tetrandrine and fangchinoline in rats at assigned time points were all successfully detected through exactly validated method. Good linearities were obtained in the range of 0.92-184 ng/mL for tetrandrine and in the range of 0.83-166 ng/mL for fangchinoline. The intra- and interday precisions for both analytes were within 11.1% and the accuracies were within the range of -10.7 to 11.3%. The developed method was then successfully applied to investigate the pharmacokinetic properties of these two alkaloids after oral administration of Stephania tetrandra S. Moore extracts and Fangji Huangqi Tang. The comparative results provided a meaningful basis for a better understanding of the practical value of the compatibility theory of traditional Chinese medicine in the clinic. PMID:25645647

    The development of an exascale computing capability with machines capable of executing O(1018) operations per second by the end of the decade will be characterized by significant and dramatic changes in computing hardware architecture from current (2014) petascale high-performance computers. From the perspective of computational science, this will be at least as disruptive as the transition from vector supercomputing to parallel supercomputing that occurred in the 1990s. This was one of the findings of a 2010 workshop on crosscutting technologies for exascale computing. The impact of these architectural changes on future applications development for the computational sciences community can now be anticipated in very general terms. While the community has been investigating the road to exascale worldwide in the last several years, there are still several barriers that need to be overcome to obtain general purpose exascale performance. Unfortunately there has been not as much progress been made, as one would have hope five or six years ago. In this presentation I will first address what is referred to as capable exascale computing and differentiate it from LINPACK exascale. I will repeat my assertion that LINPACK exascale will not be happening before 2020, and if it were, it would be inconsequential for progress in computational science. While the HPC community is working towards overcoming the barriers to capable exascale, there has been recently new progress in technologies and computational models that go beyond the CMOS based semiconductor devices and the traditional von Neumann architecture. I will highlight some recent results on these experimental machines, and assess their potential for HPC in the era past the "capable exascale".

  5. Beyond Moore's law: towards competitive quantum devices

    NASA Astrophysics Data System (ADS)

    Troyer, Matthias

    2015-05-01

    A century after the invention of quantum theory and fifty years after Bell's inequality we see the first quantum devices emerge as products that aim to be competitive with the best classical computing devices. While a universal quantum computer of non-trivial size is still out of reach there exist a number commercial and experimental devices: quantum random number generators, quantum simulators and quantum annealers. In this colloquium I will present some of these devices and validation tests we performed on them. Quantum random number generators use the inherent randomness in quantum measurements to produce true random numbers, unlike classical pseudorandom number generators which are inherently deterministic. Optical lattice emulators use ultracold atomic gases in optical lattices to mimic typical models of condensed matter physics. In my talk I will focus especially on the devices built by Canadian company D-Wave systems, which are special purpose quantum simulators for solving hard classical optimization problems. I will review the controversy around the quantum nature of these devices and will compare them to state of the art classical algorithms. I will end with an outlook towards universal quantum computing and end with the question: which important problems that are intractable even for post-exa-scale classical computers could we expect to solve once we have a universal quantum computer?

    While the move into deep water has provided exciting challenges often resulting in ingenious and novel equipment it is usually the equipment or the solution itself that is remembered and discussed. Too often one overlooks just how that novel equipment was actually installed. Perhaps one of the most exciting and ingenious equipment designs of recent times is the Submerged Turret Loading (STL) system. To date the authors have had the privilege of installing each of the 3 systems so far produced. Their work is well on course for installing the fourth during the coming summer. This paper addresses the installation of two of these systems in the summer of 94 in 350m of the hostile Halten Bank waters as part of the Conoco Heidrun development. Because the Norwegian oil industry has always been at the cutting edge of technology each new development results in the usual plethora of statistics which when presented in papers Re this are accompanied with a long list of superlatives like tallest, heaviest, deepest, quickest etc. etc. Installation work at Heidrun has a similar list. Because the 2 STL systems at Heidrun (called Direct Shuttle Loading DSL) were to be installed in such deep water the sheer size of the system components are worthy of review.

    Boone, Daniel R

    2004-09-01

    A look at the many disciplines working with voice over the past 50 years is provided from the perspective of a speech-language pathologist (SLP). Some of the earliest collaborations between medicine and speech-language pathology were seen in the management of cleft palate and velopharyngeal inadequacy problems and observed, also, in laryngectomee rehabilitation. The earlier concern of the SLP for the emotional and psychological aspects of patients with voice disorders appeared replaced with the rise of symptomatic therapy. Dramatic improvement in instrumentation assisted by computer analyses increased our awareness and understanding of both normal and disordered phonation. Although instrumentation today allows for many forms of visual feedback in voice training and therapy, this may be often at the expense of providing needed kinesthetic-proprioceptive and auditory feedback. Particular voice therapy approaches (cognitive, gestalt-holistic, imagery, resonant therapy, muscle training, and symptomatic therapy) used today are described. Suggestions are given for improving educational requirements and clinical experience in voice for SLPs. PMID:15331111

  1. Novel two-stage piezoelectric-based ocean wave energy harvesters for moored or unmoored buoys

    NASA Astrophysics Data System (ADS)

    Murray, R.; Rastegar, J.

    2009-03-01

    Harvesting mechanical energy from ocean wave oscillations for conversion to electrical energy has long been pursued as an alternative or self-contained power source. The attraction to harvesting energy from ocean waves stems from the sheer power of the wave motion, which can easily exceed 50 kW per meter of wave front. The principal barrier to harvesting this power is the very low and varying frequency of ocean waves, which generally vary from 0.1Hz to 0.5Hz. In this paper the application of a novel class of two-stage electrical energy generators to buoyant structures is presented. The generators use the buoy's interaction with the ocean waves as a low-speed input to a primary system, which, in turn, successively excites an array of vibratory elements (secondary system) into resonance - like a musician strumming a guitar. The key advantage of the present system is that by having two decoupled systems, the low frequency and highly varying buoy motion is converted into constant and much higher frequency mechanical vibrations. Electrical energy may then be harvested from the vibrating elements of the secondary system with high efficiency using piezoelectric elements. The operating principles of the novel two-stage technique are presented, including analytical formulations describing the transfer of energy between the two systems. Also, prototypical design examples are offered, as well as an in-depth computer simulation of a prototypical heaving-based wave energy harvester which generates electrical energy from the up-and-down motion of a buoy riding on the ocean's surface.

  2. One year sediment trap fluxes from a mooring in the western tropical North Atlantic

    Particle fluxes in the oceans are determined by environmental circumstances and differ from site to site. In the western tropical North Atlantic the particle flux is considered to be rather low since there is low nutrient input and low productivity. It is, however, influenced by atmospheric dust deposition, Amazon River discharge, and nitrogen fixation. This brings both refractory lithogenic material and new nutrients into the system, affecting primary production and particle export. Particle export in particular has attracted attention since it is potentially partially responsible for atmospheric CO2 sequestration. Here we present one year (October 2012 until November 2013) flux data collected by two sediment traps at 1200 m and 3500 m depth in the western tropical North Atlantic (12⁰N, 49⁰W), combined with satellite data, giving information about environmental circumstances and particle export fluxes from the surface to the deep ocean. Average total mass fluxes vary between 40 - 270 mg/m2/d and 30 - 170 mg /m2/d at the upper and lower depths, respectively. Peak fluxes during the second half of April and by the end of October/start of November 2013 are notable since they differ in nature; carbonaceous material dominates fluxes in spring and biogenic opal in fall. While the fall peak seems related to Amazon River dispersal, the spring peak appears to arise due to changing environmental conditions; rising SST possibly combined with dry dust deposition, causing a spring bloom. Both peak fluxes go along with elevated organic matter and lithogenic fluxes in the upper trap at 1200 m. At this depth, additional individual elevated lithogenic fluxes are also accompanied by raised organic matter. The lithogenic and opal fractions are considered to be the main ballast components for organic carbon aggregates, or vice versa. See: www.nioz.nl/dust

    We demonstrate numerically that non-Abelian quasihole (qh) excitations of the ν=5/2 fractional quantum Hall state have some of the key properties necessary to support quantum computation. We find that as the qh spacing is increased, the unitary transformation which describes winding two qh’s around each other converges exponentially to its asymptotic limit and that the two orthogonal wave functions describing a system with four qh’s become exponentially degenerate. We calculate the length scales for these two decays to be ξU≈2.7ℓ0 and ξE≈2.3ℓ0, respectively. Additionally, we determine which fusion channel is lower in energy when two qh’s are brought close together.

    The influence and fate of westward propagating eddies that impinge on the Kuroshio were observed with pressure sensor-equipped inverted echo sounders (PIESs) deployed east of Taiwan and northeast of Luzon. Zero lag correlations between PIES-measured acoustic travel times and satellite-measured sea surface height anomalies (SSHa), which are normally negative, have lower magnitude toward the west, suggesting the eddy-influence is weakened across the Kuroshio. The observational data reveal that impinging eddies lead to seesaw-like SSHa and pycnocline depth changes across the Kuroshio east of Taiwan, whereas analogous responses are not found in the Kuroshio northeast of Luzon. Anticyclones intensify sea surface and pycnocline slopes across the Kuroshio, while cyclones weaken these slopes, particularly east of Taiwan. During the 6 month period of overlap between the two PIES arrays, only one anticyclone affected the pycnocline depth first at the array northeast of Luzon and 21 days later in the downstream Kuroshio east of Taiwan.

    During the 404 days between 29 January 1980 and 10 March 1981 the Center conducted an uninterrupted biofouling test at Punta Tuna, Puerto Rico, of periodically cleaned, OTEC evaporator tubes. The fouling resistance (R/sub f), total surface carbon and nitrogen content, ATP, and the wet film thickness (WFT) were determined throughout the test. Visual observations of the fouling film were made by light sectioning and scanning microscopy, and at the end of the test, a study was made of the macrofouling of the flow system. The results of thest tests indicate that a base layer of bacteria and exudated polysaccharides enhance microbial adhesion and thereby create an environment conducive to rapid film growth. Fouling rates (dR/sub f//dt) for aluminum were generally higher than for titanium but they were linear for both materials and did not exceed 0.3(10/sup -4/)ft/sup 2/-h-/sup 0/F/Btu-day for either material during the 13-month study. Excellent correlation was found to exist between R/sub f/ and WFT which supports the hypothesis that it is the stagnant film of water entrapped by bacteria which is largely responsible for the insulating properties of the biofilm. The macrofouling study identified 61 species of benthic invertebrates representing ten phyla growing in those parts of the flow system, where flow was less than 3 fps but no macrofouling where the flow velocity significantly exceeded 3 fps.

    Three sets of Autonomous Temperature Line Acquisition Systems were deployed in the South China Sea. Gaps aside, the data covered nearly 3 years at the northern station and about 2 years farther south. Fluctuations ranged from episodic to interannual. Internal tides, more diurnal than semidiurnal, were active basinwide. Twelve typhoons passed during measurement periods. The most severe one, typhoon Babs in 1998, caused a temperature drop of over 7°C at 50 m. Despite strong monsoons, only near-surface temperature showed clear seasonal variations. Intraseasonal variations induced by mesoscale eddy stood out much better at subsurface depths. Propagating eddies aside, some eddies were seasonal and nearly stationary. From daily archives of an eddy-resolving, data-assimilating ocean model (East Asian Seas Nowcast/Forecast System), we identified two paradigms leading to the generation of a persistent spring-summer warm eddy in the central-western basin. In normal years, a complete cyclonic gyre was driven by a strong winter northeast monsoon. Water piled up along the periphery of the South China Sea. Afterward, a warm eddy could be generated from west of Luzon Island and propagated westward while intensifying. Under a weak northeast monsoon, such as in El Niño years, piled-up water tended to stay in the southern basin. When the wind relaxed in spring, warm water returned northward to form a warm eddy in the central-western basin. Transition from SW to NE monsoon also often led to a warm eddy generation in southern latitudes, when the summer eastward jet departing from central Vietnam broke up.

    Scaling transistors' dimensions has been the thrust for the semiconductor industry in the last four decades. However, scaling channel lengths beyond 10 nm has become exceptionally challenging due to the direct tunneling between source and drain which degrades gate control, switching functionality, and worsens power dissipation. Fortunately, the emergence of novel classes of materials with exotic properties in recent times has opened up new avenues in device design. Here, we show that by using channel materials with an anisotropic effective mass, the channel can be scaled down to 1 nm and still provide an excellent switching performance in phosphorene nanoribbon MOSFETs. To solve power consumption challenge besides dimension scaling in conventional transistors, a novel tunnel transistor is proposed which takes advantage of anisotropic mass in both ON- and OFF-state of the operation. Full-band atomistic quantum transport simulations of phosphorene nanoribbon MOSFETs and TFETs based on the new design have been performed as a proof.

    This study was designed to investigate the effect of long-term (11 years) ammonium nitrate additions on standing mass, nutrient content (% and kg ha(-1)), and the proportion of the added N retained within the different compartments of the system. The results showed that more than 90% of all N in the system was found in the soil, particularly in the organic (Oh) horizon. Added N increased the standing mass of vegetation and litter and the N content (kg N ha(-1)) of almost all measured plant, litter and soil compartments. Green tissue P and K content (kg ha(-1)) were increased, and N:P ratios were increased to levels indicative of P limitation. At the lowest treatment, most of the additional N was found in plant/litter compartments, but at higher treatments, there were steep increases in the amount of additional N in the underlying organic and mineral (Eag) horizons.

    This study wants to show the effects of active middle frequency sonar on a selected group of Italian Navy divers. Ten male divers with normal hearing were exposed to active sonar of the Italian Navy for more than 100 exposures, each of at least 1-h duration, in the course of 6 months. Before, at the end, and six months after the end of noise exposure, we performed pure-tone audiometry, Carhart test, Peyser test, thresholds of discomfort test (TDT), tympanometry, transient evoked otoacoustic emissions (TEOAE), distortion product otoacoustic emissions (DPOAE), and auditory brainstem response (ABR). At the end of the noise exposure, the audiological tests showed a worsening of the mean air and bone audiometric thresholds at the 2,000 (1/10), 4,000 (7/10), and 8,000 Hz (6/10); a fail status of the TEOAE and DPOAE, which were previously present, in all the divers; temporary threshold shift, at the Peyser test, in 9/10 divers; discomfort for pulse tone presented at the TDT test, in all the divers; no post exposure significant differences at the Carhart and ABR tests, in any of the divers. Six months after the end of noise exposure, all the divers presented a complete recovery of their audio-vestibular functions. Our results show the temporary negative effects of repeated and lasting exposure to active sonar (Hull MF) on the divers; the last control demonstrate the absence of permanent noise-induced hearing loss in divers exposed to active sonar.

    A model experiment has been performed on the successive aerobic and anaerobic degradation of oil products in samples of oil-contaminated peat sampled from a pine-subshrub-sphagnum bog near the Sutormin oilfield pipeline in the Yamal-Nenets autonomous district. During the incubation of oil-contaminated peat with lime and mineral fertilizers under complete flooding, favorable conditions are created for the aerobic oxidation of oil products at the beginning of the experiment and, as the redox potential decreases, for the anaerobic degradation of oil products conjugated with the reduction of N5+ and S+6 and methanogenesis. From the experimental data on the dynamics of the pH; Eh; and the NO{3/-}, NO{2/-}, and SO{4/2-} concentrations in the liquid phase of the samples, it has been found that denitrifiers significantly contributed to the biodegradation of oil products under the experimental conditions. After the end of the experiment, the content of oil products in the contaminated samples decreased by 21-26%.

  5. PwrSoC (integration of micro-magnetic inductors/transformers with active semiconductors) for more than Moore technologies

    NASA Astrophysics Data System (ADS)

    Mathuna, Cian Ó.; Wang, Ningning; Kulkarni, Santosh; Roy, Saibal

    2013-07-01

    This paper introduces the concept of power supply on chip (PwrSoC) which will enable the development of next-generation, functionally integrated, power management platforms with applications in dc-dc conversion, gate drives, isolated power transmission and ultimately, high granularity, on-chip, power management for mixed-signal, SOC chips. PwrSoC will integrate power passives with the power management IC, in a 3D stacked or monolithic form factor, thereby delivering the performance of a highefficiency dc-dc converter within the footprint of a low-efficiency linear regulator. A central element of the PwrSoC concept is the fabrication of power micro-magnetics on silicon to deliver micro-inductors and micro-transformers. The paper details the magnetics on silicon process which combines thin film magnetic core technology with electroplated copper conductors. Measured data for micro-inductors show inductance operation up to 20 MHz, footprints down to 0.5 mm2, efficiencies up to 93% and dc current carrying capability up to 600 mA. Measurements on micro-transformers show voltage gain of approximately - 1 dB at between 10 MHz and 30 MHz.

    2014-05-01

    The U.S. Department of Energy (DOE), through its scientific user facility, the Atmospheric Radiation Measurement (ARM) Climate Research Facility, provides scientific infrastructure and data to the international Arctic research community via its research sites located on the North Slope of Alaska. Facilities and infrastructure to support operations of unmanned aerial systems for science missions in the Arctic and North Slope of Alaska were established at Oliktok Point Alaska in 2013. Tethered instrumented balloons will be used in the near future to make measurements of clouds in the boundary layer including mixed-phase clouds. The DOE ARM Program has operated an atmospheric measurement facility in Barrow, Alaska, since 1998. Major upgrades to this facility, including scanning radars, were added in 2010. Arctic Observing Networks are essential to meet growing policy, social, commercial, and scientific needs. Calibrated, high-quality arctic geophysical datasets that span ten years or longer are especially important for climate studies, climate model initializations and validations, and for related climate policy activities. For example, atmospheric data and derived atmospheric forcing estimates are critical for sea-ice simulations. International requirements for well-coordinated, long-term, and sustained Arctic Observing Networks and easily-accessible data sets collected by those networks have been recognized by many high-level workshops and reports (Arctic Council Meetings and workshops, National Research Council reports, NSF workshops and others). The recent Sustaining Arctic Observation Network (SAON) initiative sponsored a series of workshops to "develop a set of recommendations on how to achieve long-term Arctic-wide observing activities that provide free, open, and timely access to high-quality data that will realize pan-Arctic and global value-added services and provide societal benefits." This poster will present information on opportunities for members of the arctic research community to make atmospheric measurements using unmanned aerial systems or tethered balloons.

    Large quantities of dust are transported from the Sahara Desert across the Atlantic Ocean towards the Caribbean each year, with a large portion of it deposited in the ocean. This dust brings an array of minerals, nutrients and organic matter, both living and dead. This input potentially fertilizes phytoplankton growth, with resulting knock-on effects throughout the food chain. The input of terrestrial microbial life may also have an impact on the marine microbial community. The current multi-year project consists of a transect of floating dust collectors and sub-surface sediment traps placed at 12°N across the Atlantic Ocean. Sediment traps are located 1200m and 3500m below the sea surface and all are synchronized to collect samples for a period of two weeks. The aim is to understand the links between dust input and the bacterial community and how this relates to ocean productivity and the carbon cycle. The first set of sediment trap samples were recovered using the RV Pelagia in November 2013 with promising results. Results from 7 sediment traps (three at 1200m and four at 3500m) were obtained. In general, the total mass flux decreased as distance from the source increased and the upper traps generally held more material than those at 3500m. Denaturing Gradient Gel Electrophoresis (DGGE) was used as a screening technique, revealing highly varied profiles, with the upper (1200m) traps generally showing more variation throughout the year. Several samples have been submitted for high throughput DNA sequencing which will identify the variations in these samples.

  9. Simulation analysis of moored fluorometer time series from the Mid-Atlantic Bight during 1987--1990

    1990-01-01

    The goal of the previous research during 1987-1990 within the DOE (Department of Energy) Shelf Edge Exchange Processes (SEEP) program in the Mid-Atlantic Bight was to understand the physical and biogeochemical processes effecting the diffusive exchange of the proxies of energy-related, by-products associated with particulate matter between estuarine, shelf, and slope waters on this continental margin. As originally envisioned in the SEEP program plan, SEEP-III would take place at Cape Hatteras to study the advective exchange of materials by a major boundary current. One problem of continuing interest is the determination of the local assimilative capacity of slope waters and sediments off the eastern seaboard of the US to lengthen the pathway between potentially harmful energy by-products and man. At basin scales, realistic specification of the lateral transport by western boundary currents of particulate matter is a necessary input to global models of carbon/nitrogen cycling. Finally, at these global scales, the generic role of continental margins in cycling greenhouse gases, e.g. CO{sub 2}, CH{sub 4}, and N{sub 2}O, is now of equal interest. This continuing research of model construction and evaluation within the SEEP program focuses on all three questions at local, regional, and basin scales. Results from SEEP-I and II are discussed as well as plans for SEEP-III. 14 figs., 3 tabs.

    The structure and properties of oligotrophic peat, oligotrophic peat gley, and pyrogenic oligotrophic peat soils identified on a plot 0.5 km2 in area in the northeast of Sakhalin Island have been studied. The vertical distributions of physicochemical, chemical, and ecotoxicological parameters in the profiles of some bog soil groups have been considered. An increase in ash content, a less acid reaction, and a deficit of available nitrogen and potassium have been revealed in the upper horizons of pyrogenic soils. No accumulation of mobile heavy metals is manifested in the pyrogenic horizons of peat soils. Statistical parameters of the spatial variation in pHKCl and total acidity, as well as the contents of ash, available phosphorus, exchangeable potassium, ammonium and nitrate nitrogen, mobile heavy metals (Cr, Ni, Cu, Zn, Cd, Pb), and benzo[ a]pyrene, have been calculated for the moss and sublitter horizons. The variation coefficients are 30-100% for most of the studied parameters and reach 100-200% for available phosphorus; ammonium nitrogen; and mobile Ni, Cu, Zn, and Cd. An increase in the content of benzo[ a]pyrene, although without MPC exceedance, is noted in the moss of pyrogenic soils and the peat horizons untouched by fires.

  11. SeaMon-HC Buoy. A specific real-time-lightweight-moored platform as a tool for fast hydrocarbon detection

    2009-04-01

    The present paper-work describes the design, last development stages and the derived results from a specific buoy platform for fast hydrocarbon detection in seawater. Under the name of SeaMon-HC, (Patent No. P200302219/8) the buoy represents a very chief tool for coastal monitoring, mainly surrounding areas with a high oil-spill risk level, like harbours, off-shore fish farming, beaches and so on. Nowadays, the Macaronesian area has nine units working in real-time, under the frame of the Red ACOMAR Network. The main innovative aspect from this buoy is the detection system. It's based in polymer technology, working as a resistance, who increase its value when the pollutant on water surface is detected. The response time from the sensor is a direct function of the hydrocarbon volatility level. For hydrocarbons with high volatility levels (like petrol), the sensor needs less time (around 3 minutes) than others with less volatility such as oils. SeaMon-HC is an autonomous, modular, reusable and a very low-cost development integrated by four subsystems (SS): SS-Flotation (different materials and shapes available); SS-Sensors (hydrocarbon detector and additional sensors -up to 15-, to solve specific sensor configuration requirements); SS-Power Supply (equipped in its basic configuration with a couple of solar modules and two 12V batteries) and the SS-Communication (based on a RF or GSM/GPRS modem technology, with a selectable communication frequency). All SeaMon-HC units, as well the rest of the ODAS buoys who joint together the Red ACOMAR Network, works in real-time, sending the collected information to the control centre that manages the communications, providing data, in a useful form (as a web site), to diverse socio-economic important sectors which make an exhaustive use of the littoral in the Macaronesian region. The access to the information by the users is done through a specific GIS software application.

    2013-01-01

    The prepupation caterpillar of the Southeast Asian moth Calindoea trifascialis constructs a leaf shelter that jumps across the ground using a jumping method novel among the insects. We found that movement path direction was correlated to the direction opposite to the most intense light. Correlated random walk (CRW) analyses found net squared displacements higher than predicted by a CRW, and fractal dimension analysis indicated straighter paths at large spatial scales. Rearing experiments showed high mortality from predation on the ground, but higher mortality resulted from sun exposure. We interpret jumping path orientation as an efficient search strategy to find shade in a variable landscape, given limited perception, in the presence of overheating and desiccation risks.

    A two-layered baroclinic circulation model and a 21-layered biochemical model are used to explore the consequences of Loop Current-induced upwelling and terrestrial eutrophication on ''new''production within the Gulf of Mexico. During a quasi-annual penetration and eddy-shedding cycle of the Loop Current, the simulated seasonal changes of incident radiation, wind stress, and surface mixed layer depth induce an annual cycle of algal biomass that corresponds to in situ and satellite time series of chlorophyll. The simulated nitrate fields match those of shipboard surveys, while fallout of particulate matter approximates that caught in sediment traps and accumulating in bottom sediments. Assuming an f ratio of 0.06--0.12, the total primary production of the Gulf of Mexico might be 105--210 g C m /sup /minus//2 yr/sup /minus//1 in the absence of anthropogenic nutrient loadings, i.e., 2--3 fold that of oligotrophic regions not impacted by western boundary currents. Less than 25% of the nitrogen effluent of the Mississippi River may be stored in bottom sediments, with most of this input dispersed in dissolved form beneath the pycnocline, after remineralization of particulate detritus within several production cycles derived from riverine loading. At a sinking rate of 3 m day /sup /minus//1, however, sufficient phytodetritus survives oxidation in the water column to balance estimates of bottom metabolism and burial at the margins.

    This study was designed to investigate the leaching response of an upland moorland to long-term (10 yr) ammonium nitrate additions of 40, 80 and 120 kg N ha(-1) yr(-1) and to relate this response to other indications of potential system damage, such as acidification and cation displacement. Results showed increases in nitrate leaching only in response to high rates of N input, in excess of 96 and 136 kg total N input ha(-1) yr(-1) for the organic Oh horizon and mineral Eag horizon, respectively. Individual N additions did not alter ammonium leaching from either horizon and ammonium was completely retained by the mineral horizon. Leaching of dissolved organic nitrogen (DON) from the Oh horizon was increased by the addition of 40 kg N ha(-1) yr(-1), but in spite of increases, retention of total dissolved nitrogen reached a maximum of 92% and 95% of 80 kg added N ha(-1) yr(-1) in the Oh and Eag horizons, respectively. Calcium concentrations and calcium/aluminium ratios were decreased in the Eag horizon solution with significant acidification mainly in the Oh horizon leachate. Nitrate leaching is currently regarded as an early indication of N saturation in forest systems. Litter C:N ratios were significantly lowered but values remained above a threshold predicted to increase leaching of N in forests.

    We deployed CO{sub 2} and O{sub 2} sensors on the US continental shelf off Cape Hatteras, North Carolina, during late summer 1994. A continuous 32-d gas record was obtained at 20 m in 25 m of water, below the thermocline for most of the period. Analysis of the correlation between CO{sub 2} and O{sub 2} indicates that biological and advective processes dominated the gas variability, with small or insignificant fluxes due to air-sea exchange, vertical eddy diffusion, and carbonate dissolution or formation. The observed O{sub 2}; CO{sub 2} correlation was 1.39, within the range predicted for the photosynthetic quotient. Photosynthesis and respiration appeared to be tightly coupled, resulting in no net community production in these waters during the late summer. It is evident from these results that the combination of moooring-based CO{sub 2} and O{sub 2} measurements will be a powerful tool for studying the marine carbon cycle. 33 refs., 6 figs., 1 tab.

    During 25 years ecology and population dynamic of two brown frog species (Rana temporaria and R. arvalis) were studied in Moscow region, Solovki island and South Ural. We compared life cycles characteristics, namely biotope preferences, diet, migration, enemies, hibernation places using own and available literature data. Then we analyse how these parameters are changed among the species area and ecological niches were compared. We found that these two species do not compete in any stage of life cycle. Ecological niches are very closed and differences are determined generally by abiotic factors. So, R. temporaria prefers more wet biotope and more sensitive to acidity (low pH value). Differences in spawning time do not associate with interference in spawning places. We conclude that interspecific competition did not take place neither in the past nor in present and the reason of differences in ecological niches are determined by separate ways of evolutionary development of these species.

    During the last two decades, several effects of acidification have been shown, e.g., enhanced leaching of metals from sediments and soil. Furthermore, an increased growth of Sphagnum aurantiacum frequently occurs in acidified waters. The aim of the present study is to investigate some effects of acidification on the embryological development on two Anurans. The toxicity of aluminium is thought to vary with pH. The highest toxicity of aluminium in the hydroxyl form have been found at pH 5. In the present study a laboratory experiment was performed to investigate the toxicity of Al to frog embryos in water with pH 5.0. In acidified waters Sphagnum and especially S. aurantiacum, is competitive and quickly become established. It has been indicated that frog spawn deposited on Sphagnum show an unusually high mortality and questions have been raised if Sphagnum reinforces the detrimental effects of acidification on Anuran reproduction.

  14. Soil and Plant Mercury Concentrations and Pools in the Arctic Tundra of Northern Alaska by Hedge Christine, Obrist Daniel, Agnan Yannick, Moore Christopher, Biester Harald, Helmig Detlev

    We present vegetation, soil and runoff mercury (Hg) concentrations and pool sizes in vegetation and soils at several arctic tundra sites, an area that represents <7 x 106 km2 of land surface globally. The primary measurement location is at Toolik Field Station (TFS, 68° 38' N) in northern Alaska, with additional samples collected along a transect from TFS to the Arctic Ocean, and in Noatak National Preserve to be collected in August 2015. Soil and vegetation samples from all sites will be analyzed for total Hg concentration, pH, soil texture, bulk density, soil moisture content, organic and total carbon (C), nitrogen, along with major and trace elements. Initial results already obtained from TFS (characterized as moist to wet tundra with Typic Aquiturbel soils) show Hg concentrations in tundra vegetation (112±15 μg kg-1) and organic soil (140±8 μg kg-1) similar to those found in temperate sites. Calculation of plant-based Hg deposition rates by litterfall of 17.3 μg kg-1 yr-1 were surprisingly high, exceeding all other Hg deposition fluxes at this site. Hg concentrations in mineral soils (95±3 μg kg-1) were 2-3 times higher than those found at temperate sites. Hg concentrations showed weak relationships to organic C concentrations contrasting patterns from temperate soils where concentrations typically decline with depth following lower organic carbon contents. In fact, vertical mass profiles of Hg showed a strong increase with depth, with mineral layers storing over 90% (200-500 g ha-1) of Hg within these soils. A principle component analysis including major and trace elements indicated that soil Hg was not of lithogenic origin but from atmospheric sources, possibly by long-range transport. Carbon-14 dating results showed over 7,000 years old organic carbon in mineral soils of the active layer where highest concentrations of soil Hg were observed, suggesting long term retention of atmospheric Hg. These patterns suggest vertical translocation of Hg from the surface organic horizons to mineral soils and strong accumulation—possibly over millennia—therein.

  17. Complexity and Performance Results for Non FFT-Based Univariate Polynomial Multiplication

    NASA Astrophysics Data System (ADS)

    Chowdhury, Muhammad F. I.; Maza, Marc Moreno; Pan, Wei; Schost, Eric

    2011-11-01

    Today's parallel hardware architectures and computer memory hierarchies enforce revisiting fundamental algorithms which were often designed with algebraic complexity as the main complexity measure and with sequential running time as the main performance counter. This study is devoted to two algorithms of univariate polynomial multiplication; that are independent of the coefficient ring: the plain and the Toom-Cook univariate multiplications. We analyze their cache complexity and report on their parallel implementations in Cilk++ [1].

  18. Neutron Resonance Parameters of 238U and the Calculated Cross Sections from the Reich-Moore Analysis of Experimental Data in the Neutron Energy Range from 0 keV to 20 keV

    SciTech Connect

    Derrien, H

    2005-12-05

    The neutron resonance parameters of {sup 238}U were obtained from a SAMMY analysis of high-resolution neutron transmission measurements and high-resolution capture cross section measurements performed at the Oak Ridge Electron Linear Accelerator (ORELA) in the years 1970-1990, and from more recent transmission and capture cross section measurements performed at the Geel Linear Accelerator (GELINA). Compared with previous evaluations, the energy range for this resonance analysis was extended from 10 to 20 keV, taking advantage of the high resolution of the most recent ORELA transmission measurements. The experimental database and the method of analysis are described in this report. The neutron transmissions and the capture cross sections calculated with the resonance parameters are compared with the experimental data. A description is given of the statistical properties of the resonance parameters and of the recommended values of the average parameters. The new evaluation results in a slight decrease of the effective capture resonance integral and improves the prediction of integral thermal benchmarks by 70 pcm to 200 pcm.

  19. Development of a Large Set of Microsatellite Markers in Zapote Mamey (Pouteria sapota (Jacq.) H.E. Moore & Stearn) and Their Potential Use in the Study of the Species.

    Pouteria sapota is known for its edible fruits that contain unique carotenoids, as well as for its fungitoxic, anti-inflammatory and anti-oxidant activity. However, its genetics is mostly unknown, including aspects about its genetic diversity and domestication process. We did high-throughput sequencing of microsatellite-enriched libraries of P. sapota, generated 5223 contig DNA sequences, 1.8 Mbp, developed 368 microsatellites markers and tested them on 29 individuals from 10 populations (seven wild, three cultivated) from Mexico, its putative domestication center. Gene ontology BLAST analysis of the DNA sequences containing microsatellites showed potential association to physiological functions. Genetic diversity was slightly higher in cultivated than in the wild gene pool (HE = 0.41 and HE = 0.35, respectively), although modified Garza-Williamson Index and Bottleneck software showed evidence for a reduction in genetic diversity for the cultivated one. Neighbor Joining, 3D Principal Coordinates Analysis and assignment tests grouped most individuals according to their geographic origin but no clear separation was observed between wild or cultivated gene pools due to, perhaps, the existence of several admixed populations. The developed microsatellites have a great potential in genetic population and domestication studies of P. sapota but additional sampling will be necessary to better understand how the domestication process has impacted the genetic diversity of this fruit crop.

  14. Evaluation of station keeping systems for deepwater drilling semi-submersibles

    NASA Astrophysics Data System (ADS)

    Song, An-Ke; Sun, Li-Ping; Luo, Yong; Wang, Qiang

    2010-09-01

    This paper addresses the need for systematic evaluation of the station keeping systems of deepwater drilling semi-submersibles. Based on the selected drilling semi-submersible configuration, the mooring systems were analyzed and designed for a range of water depths using different mooring line materials. These were steel wire rope, polyester rope and HMPE (high modulus poly ethylene). The mooring analysis was carried out using the advanced fully coupled time domain analysis method in the computer software package HARP. Diffraction analysis was first applied to solve the hydrodynamic properties of the vessel and then the motion equations of the complete dynamic system including the drilling rig, the mooring lines and risers were developed and solved in the time domain. Applying the advanced analysis method, a matrix of mooring systems was developed for operating in water depths of 1 000 m, 1 500 m, and 2 000 m using various mooring materials. The development of mooring systems was conducted in accordance with the commonly adopted mooring design code, API RP 2SK and API RP 2SM. Fresh attempts were then made to comparatively evaluate the mooring system’s characteristics and global performance. Useful results have been obtained in terms of mooring materials, water depths, and key parameters of mooring configurations. The results provide in-depth insight for the design and operation of deepwater mooring systems in the South China Sea environment.

  18. Study of ground handling characteristics of a maritime patrol airship

    NASA Technical Reports Server (NTRS)

    1981-01-01

    Mooring concepts appropriate for maritime patrol airship (MPA) vehicles are investigated. The evolution of ground handling systems and procedures for all airship types is reviewed to ensure that appropriate consideration is given to past experiences. A tri-rotor maritime patrol airship is identified and described. Wind loads on a moored airship and the effects of these loads on vehicle design are analyzed. Several mooring concepts are assessed with respect to the airship design, wind loads, and mooring site considerations. Basing requirements and applicability of expeditionary mooring also are addressed.

    A preliminary investigation of mooring concepts appropriate for heavy lift buoyant quad rotor (BQR) vehicles was performed. A review of the evolution of ground handling systems and procedures for all airship types is presented to ensure that appropriate consideration is given to past experiences. Two buoyant quad rotor designs are identified and described. An analysis of wind loads on a moored airship and the effects of these loads on vehicle design is provided. Four mooring concepts are assessed with respect to the airship design, wind loads and mooring site considerations. Basing requirements and applicability of expeditionary mooring at various operational scenarios are addressed.

  20. Critical Probabilities and Convergence Time of Percolation Probabilistic Cellular Automata

    NASA Astrophysics Data System (ADS)

    Taggi, Lorenzo

    2015-05-01

    This paper considers a class of probabilistic cellular automata undergoing a phase transition with an absorbing state. Denoting by the neighbourhood of site , the transition probability is if or otherwise, . For any there exists a non-trivial critical probability that separates a phase with an absorbing state from a fluctuating phase. This paper studies how the neighbourhood affects the value of and provides lower bounds for . Furthermore, by using dynamic renormalization techniques, we prove that the expected convergence time of the processes on a finite space with periodic boundaries grows exponentially (resp. logarithmically) with the system size if (resp. ). This provides a partial answer to an open problem in Toom et al. (Stochastic Cellular Systems: Ergodicity, Memory, Morphogenesis, pp. 1-182. Manchester University Press, Manchester, 1990; Topics in Contemporary Probability and its Applications, pp. 117-157. CRC Press, Boca Raton, 1995).

    2012-11-01

    Two novel obligately anaerobic, Gram-stain-positive, saccharolytic and non-proteolytic spore-forming bacilli (strains CD3:22(T) and N1(T)) are described. Strain CD3:22(T) was isolated from a biopsy of the small intestine of a child with coeliac disease, and strain N1(T) from the saliva of a healthy young man. The cells of both strains were observed to be filamentous, approximately 5 to >20 µm long, some of them curving and with swellings. The novel organisms produced H(2)S, NH(3), butyric acid and acetic acid as major metabolic end products. Phylogenetic analyses, based on comparative 16S rRNA gene sequencing, revealed close relationships (98% sequence similarity) between the two isolates, as well as the type strain of Eubacterium saburreum and four other Lachnospiraceae bacterium-/E. saburreum-like organisms. This group of bacteria were clearly different from any of the 19 known genera in the family Lachnospiraceae. While Eubacterium species are reported to be non-spore-forming, reanalysis of E. saburreum CCUG 28089(T) confirmed that the bacterium is indeed able to form spores. Based on 16S rRNA gene sequencing, phenotypic and biochemical properties, strains CD3:22(T) and N1(T) represent novel species of a new and distinct genus, named Lachnoanaerobaculum gen. nov., in the family Lachnospiraceae [within the order Clostridiales, class Clostridia, phylum Firmicutes]. Strain CD3:22(T) (=CCUG 58757(T) =DSM 23576(T)) is the type strain of the type species, Lachnoanaerobaculum umeaense gen. nov., sp. nov., of the proposed new genus. Strain N1(T) (=CCUG 60305(T)=DSM 24553(T)) is the type strain of Lachnoanaerobaculum orale sp. nov. Moreover, Eubacterium saburreum is reclassified as Lachnoanaerobaculum saburreum comb. nov. (type strain CCUG 28089(T) =ATCC 33271(T) =CIP 105341(T) =DSM 3986(T) =JCM 11021(T) =VPI 11763(T)).
