Claiming Darwin: Stephen Jay Gould in contests over evolutionary orthodoxy and public perception, 1977-2002.  

PubMed

This article analyzes the impact of the resurgence of American creationism in the early 1980s on debates within post-synthesis evolutionary biology. During this period, many evolutionists criticized Harvard biologist Stephen Jay Gould for publicizing his revisions to traditional Darwinian theory and opening evolution to criticism by creationists. Gould's theory of punctuated equilibrium was a significant source of contention in these disputes. Both he and his critics, including Richard Dawkins, claimed to be carrying the mantle of Darwinian evolution. By the end of the 1990s, the debate over which evolutionary thinkers were the rightful heirs to Darwin's evolutionary theory was also a conversation over whether Darwinism could be defended against creationists in the broader cultural context. Gould and others' claims to Darwin shaped the contours of a political, religious and scientific controversy. PMID:24457049

Stephen Jay Kline on systems, or physics, complex systems, and the gap between.  

SciTech Connect

At the end of his life, Stephen Jay Kline, longtime professor of mechanical engineering at Stanford University, completed a book on how to address complex systems. The title of the book is 'Conceptual Foundations of Multi-Disciplinary Thinking' (1995), but the topic of the book is systems. Kline first establishes certain limits that are characteristic of our conscious minds. Kline then establishes a complexity measure for systems and uses that complexity measure to develop a hierarchy of systems. Kline then argues that our minds, due to their characteristic limitations, are unable to model the complex systems in that hierarchy. Computers are of no help to us here. Our attempts at modeling these complex systems are based on the way we successfully model some simple systems, in particular, 'inert, naturally-occurring' objects and processes, such as what is the focus of physics. But complex systems overwhelm such attempts. As a result, the best we can do in working with these complex systems is to use a heuristic, what Kline calls the 'Guideline for Complex Systems.' Kline documents the problems that have developed due to 'oversimple' system models and from the inappropriate application of a system model from one domain to another. One prominent such problem is the Procrustean attempt to make the disciplines that deal with complex systems be 'physics-like.' Physics deals with simple systems, not complex ones, using Kline's complexity measure. The models that physics has developed are inappropriate for complex systems. Kline documents a number of the wasteful and dangerous fallacies of this type.

Many ways of being human, the Stephen J. Gould's legacy to Palaeo-Anthropology (2002-2012).  

PubMed

As an invertebrate palaeontologist and evolutionary theorist, Stephen J. Gould did not publish any direct experimental results in palaeo-anthropology (with the exception of Pilbeam and Gould, 1974), but he did prepare the stage for many debates within the discipline. We argue here that his scientific legacy in the anthropological fields has a clear and coherent conceptual structure. It is based on four main pillars: (1) the famed deconstruction of the "ladder of progress" as an influential metaphor in human evolution; (2) Punctuated Equilibria and their significance in human macro-evolution viewed as a directionless "bushy tree" of species; (3) the trade-offs between functional and structural factors in evolution and the notion of exaptation; (4) delayed growth, or neoteny, as an evidence in human evolution. These keystones should be considered as consequences of the enduring theoretical legacy of the eminent Harvard evolutionist: the proposal of an extended and revised Darwinism, coherently outlined in the last twenty years of his life (1982-2002) and set out in 2002 in his final work, The Structure of Evolutionary Theory. It is in the light of his "Darwinian pluralism", able to integrate in a new frame the multiplicity of explanatory patterns emerging from different evolutionary fields, that we understand Stephen J. Gould's legacy in palaeo-anthropology today, both in terms of provocative shocks to comfortable visions of human evolution and, above all, in terms of specific scientific predictions about future research.

Gould Belt Origin  

NASA Astrophysics Data System (ADS)

Using archive VLA data and recent observations on the Karl G. Jansky Very Large Array it is worked on a semi-automatic python/CASA code to select, reduce and plot several young stars belonging to the Ophiuchus core. This code mean to help to select observations made along the 30 years of the VLA done in the selected area with the wide configurations A and B, and in the X and C band, to determine their position and compare it with the most recent ones. In this way it is possible to determinate their proper motion with very high precision. It is presented the phases of the process and our first results worked on three well know stars: S1, DoAr 21 and VLA1623. This is the tip of a bigger work that includes Taurus molecular cloud and other important recent star formation regions belonging to the Gould Belt. Our goal is to support the most suitable among several theories about Gould Belt origin or provide a new one taking in count the dynamics of those regions.

The discrete Gould transform and its applications  

NASA Astrophysics Data System (ADS)

We present a new discrete transform, the Gould transform (DGT). The transform has many interesting mathematical properties. For example, the forward and inverse transform matrices are both lower triangular, with constant diagonals and sub-diagonals and both can be factored into the product of binary matrices. The forward transform can be used to detect edges in digital images. If G is the forward transform matrix and y is the image, then the two dimensional DGT, GyG T can be used directly to detect edges. Ways to improve the edge detection technique is to use the "combination of forward and backward difference", G T(Gy) to better identify the edges. For images that tend to have vertical and horizontal edges, we can further improve the technique by shifting rows (or columns), and then use the technique to detect edges, essentially applying the transform in the diagonal directions.

Level II scour analysis for Bridge 22 (JAY-TH00400022) on Town Highway 40, crossing Jay Branch, Jay, Vermont  

USGS Publications Warehouse

8). A Level II study is a basic engineering analysis of the site, including a quantitative analysis of stream stability and scour (U.S. Department of Transportation, 1993). Results of a Level I scour investigation also are included in Appendix E of this report. A Level I investigation provides a qualitative geomorphic characterization of the study site. Information on the bridge, gleaned from Vermont Agency of Transportation (VTAOT) files, was compiled prior to conducting Level I and Level II analyses and is found in Appendix D. The site is in the Green Mountain section of the New England physiographic province in northern Vermont. The 2.15-mi2 drainage area is in a predominantly rural and forested basin. In the vicinity of the study site, the surface cover is primarily pasture on the upstream and downstream left overbank while the immediate banks have dense woody vegetation. The downstream right overbank of the bridge is forested. In the study area, Jay Branch Tributary has an incised, sinuous channel with a slope of approximately 0.02 ft/ft, an average channel top width of 26 ft and an average bank height of 3 ft. The channel bed material ranges from gravel to cobble with a median grain size (D50) of 40.5 mm (0.133 ft). The geomorphic assessment at the time of the Level I and Level II site visit on June 7, 1995, indicated that the reach was stable. The Town Highway 40 crossing of Jay Branch Tributary is a 27-ft-long, two-lane bridge consisting of one 25-foot steel-beam span (Vermont Agency of Transportation, written communication, March 6, 1995). The opening length of the structure parallel to the bridge face is 23.5 ft. The bridge is supported by vertical, concrete abutments with wingwalls. The channel skew and the opening-skew-to-roadway are zero degrees. The scour counter-measures at the site included type-2 stone fill (less than 36 inches diameter) at the upstream end of the left and right abutments, at the upstream right wingwall, and at the downstream left wingwall. There was also type-3 stone fill (less than 48 inches diameter) at the upstream left and downstream right wingwall. Additional details describing conditions at the site are included in the Level II Summary and Appendices D and E. Scour depths and recommended rock rip-rap sizes were computed using the general guidelines described in Hydraulic Engineering Circular 18 (Richardson and others, 1995). Total scour at a highway crossing is comprised of three components: 1) long-term streambed degradation; 2) contraction scour (due to accelerated flow caused by a reduction in flow area at a bridge) and; 3) local scour (caused by accelerated flow around piers and abutments). Total scour is the sum of the three components. Equations are available to compute depths for contraction and local scour and a summary of the results of these computations follows. Contraction scour for all modelled flows ranged from 0.7 to 1.1 ft. The worst-case contraction scour occurred at the 500-year discharge. Left abutment scour ranged from 4.6 to 4.9 ft. The worst-case left abutment scour occurred at the 100-year discharge. Right abutment scour ranged from 4.0 to 5.0 ft. The worst-case right abutment scour occurred at the 500-year discharge. Additional information on scour depths and depths to armoring are included in the section titled “Scour Results”. Scoured-streambed elevations, based on the calculated scour depths, are presented in tables 1 and 2. A cross-section of the scour computed at the bridge is presented in figure 8. Scour depths were calculated assuming an infinite depth of erosive material and a homogeneous particle-size distribution. It is generally accepted that the Froehlich equation (abutment scour) gives “excessively conservative estimates of scour depths” (Richardson and others, 1995, p. 47). Usually, computed scour depths are evaluated in combination with other information i

Kinematics of Gould Belt Based on Open Clusters (Bobylev, 2006)  

NASA Astrophysics Data System (ADS)

We have redetermined kinematic parameters of the Gould Belt using currently available data on the motion of nearby young (logt<7.91) open clusters, OB associations, and moving stellar groups. Our modeling shows that the residual velocities reach their maximum values of -4km/s for rotation (in the direction of Galactic rotation) and +4km/s for expansion at a distance from the kinematic center of 300pc. We have taken the following parameters of the Gould Belt center: R0=150pc and l0=128{deg}. The whole structure is shown to move relative to the local standard of rest at a velocity of 10.7+/-0.7km/s in the direction l=274+/-4{deg} and b=-1+/-3{deg}. Using the derived rotation velocity, we have estimated the virial mass of the Gould Belt to be 1.5 million solar masses. (2 data files).

Arboviral infection in two species of wild jays (Aves: Corvidae): evidence for population impacts.  

PubMed

We examined the prevalence of antibodies to three mosquito-borne arboviruses in blue jays, Cyanocitta cristata, and Florida scrub-jays, Aphelocoma coerulescens, to identify the effects on host survival, the influence of sex and age on infection, and the temporal patterns of antibody prevalence. Blood samples from 306 blue jays and 219 Florida scrub-jays were collected at Archbold Biological Station (Lake Placid, FL) from April 1994 through December 1995. Sera were analyzed for hemagglutination-inhibition antibody to eastern equine encephalitis (EEE) and St. Louis encephalitis (SLE) viruses, and neutralizing antibodies to EEE, Highlands J (HJ), and SLE viruses. Overall, 31.4% of blue jay samples and 22.1% of scrub-jay samples had antibodies to EEE. Antibodies to HJ were detected in slightly >15% of samples in each jay species, and SLE was detected in <3% of the samples in each jay species. A single EEE virus isolation was made from the blood of an 11-d-old scrub-jay nestling. Survival of adult blue jays seropositive to EEE was significantly lower than that of seronegative birds based on resight rates, but infection did not seem to affect survival of adult or juvenile Florida scrub-jays.

Habitat model for the Florida Scrub Jay on John F. Kennedy Space Center  

NASA Technical Reports Server (NTRS)

The Florida Scrub Jay is endemic to Florida. The John F. Kennedy Space Center (KSC) provides habitat for one of the three largest populations of the Florida Scrub Jay. This threatened bird occupies scrub, slash pine flatwoods, disturbed scrub, and coastal strand on KSC. Densities of Florida Scrub Jays were shown to vary with habitat characteristics but not necessarily with vegetation type. Relationships between Florida Scrub Jay densities and habitat characteristics were used to develop a habitat model to provide a tool to compare alternative sites for new facilities and to quantify environmental impacts. This model is being tested using long term demographic studies of colorbanded Florida Scrub Jays. Optimal habitat predicted by the model has greater than or equal to 50 percent of the shrub canopy comprised of scrub oaks, 20-50 percent open space or scrub oak vegetation within 100 m of a ruderal edge, less than or equal to 15 percent pine canopy cover, a shrub height of 120-170 cm, and is greater than or equal to 100 m from a forest. This document reviews life history, social behavior, food, foraging habitat, cover requirements, characteristics of habitat on KSC, and habitat preferences of the Florida Scrub Jay. Construction of the model and its limitations are discussed.

Time Restored - The Harrison Timekeepers and R.T. Gould, the Man Who Knew (Almost) Everything  

NASA Astrophysics Data System (ADS)

This is the story of Rupert T. Gould (1890-1948), the polymath and horologist. A remarkable man, Lt Cmdr Gould made important contributions in an extraordinary range of subject areas throughout his relatively short and dramatically troubled life. From antique clocks to scientific mysteries, from typewriters to the first systematic study of the Loch Ness Monster, Gould studied and published on them all. With the title The Stargazer, Gould was an early broadcaster on the BBC's Children's Hour when, with his encyclopaedic knowledge, he became known as The Man Who Knew Everything. Not surprisingly, he was also part of that elite group on BBC radio who formed The Brains Trust, giving on-the-spot answers to all manner of wide ranging and difficult questions. With his wide learning and photographic memory, Gould awed a national audience, becoming one of the era's radio celebrities. During the 1920s Gould restored the complex and highly significant marine timekeepers constructed by John Harrison (1693-1776), and wrote the unsurpassed classic, The Marine Chronometer, its History and Development . Today he is virtually unknown, his horological contributions scarcely mentioned in Dava Sobel's bestseller Longitude. The TV version of Longitude, in which Jeremy Irons played Rupert Gould, did at least introduce Gould's name to a wider public. Gould suffered terrible bouts of depression, resulting in a number of nervous breakdowns. These, coupled with his obsessive and pedantic nature, led to a scandalously-reported separation from his wife and cost him his family, his home, his job, and his closest friends. In this first-ever biography of Rupert Gould, Jonathan Betts, the Royal Observatory Greenwich's Senior Horologist, has given us a compelling account of a talented but flawed individual. Using hitherto unknown personal journals, the family's extensive collection of photographs, and the polymath's surviving records and notes, Betts tells the story of how Gould's early life, his naval career, and his celebrity status came together as this talented Englishman restored part of Britain's--and the world's--most important technical heritage: John Harrison's marine timekeepers.

Apparent predation by Gray Jays, Perisoreus canadensis, on Long-toed Salamanders, Ambystoma macrodactylum, in the Oregon Cascade Range  

USGS Publications Warehouse

We report observations of Gray Jays (Perisoreus canadensis) appearing to consume larval Long-toed Salamanders (Ambystoma macrodactylum) in a drying subalpine pond in Oregon, USA. Corvids are known to prey upon a variety of anuran amphibians, but to our knowledge, this is the first report of predation by any corvid on aquatic salamanders. Long-toed Salamanders appear palatable to Gray Jays, and may provide a food resource to Gray Jays when salamander larvae are concentrated in drying temporary ponds.

Uranometria Argentina catalog of bright southern stars (Gould, 1879)  

NASA Astrophysics Data System (ADS)

In 1879 Benjamin Apthorp Gould published in Buenos Aires, Argentina, the Uranometria Argentina catalog of 7756 stars south of declination +10 degrees. This included all those stars he considered magnitude 7 or brighter and some fainter stars which are close companions to brighter stars or to each other and have combined magnitude 7 or brighter. Star positions are in 1875 coordinates, and constellation boundaries also in 1875 coordinates were defined within the aforementioned declination range. With only a few small changes these were incorporated into the boundaries adopted by the IAU in 1930 and subsequently universally accepted. In terms of accurate photoelectric magnitude measurements the Uranometria Argentina is nearly complete to magnitude 6.5 in its declination range. In each constellation the individual stars considered to be magnitude 7 and brighter were numbered in sequence of increasing right ascension in 1875 coordinates, except that in a few cases this sequence was somewhat adjusted so that stars close together could be listed on adjacent lines of text. The numbering system is analogous to that in the Flamsteed Catalogus Brittanicus and now widely used. Star numbers from the Uranometria Argentina rarely appear in the 21st century despite the potential utility of their use. They were included in the American Ephemeris and Nautical Almanac until 1978, and in the FK5 catalog until 1999, always with the letter G following the number in the Uranometria Argentina catalog. This serves to distinguish Flamsteed numbers with no following letters from Gould numbers, and is utilized in this presentation and recommended for general use. The file catalog.dat includes every star in the original Uranometria Argentina. In the original the constellations were presented in sequence of increasing distance from the south pole and numbered accordingly. For the convenience of 21st century astronomers the constellations are presented here by alphabetical sequence in constellation name and the stars in each constellation in the same sequence as in the original. A separate file notes.txt includes a large number of notes for individual stars and for groups of stars recognized in the original catalog as belonging together. Each note is referenced by an asterisk * in the file catalog.dat. Columns 43-63 provide J2000 coordinates and cross identifications from the Flamsteed, HD, and SAO catalogs for the stars and have been added by the author of this data set. Columns 82-154 have been copied verbatim from the Uranometria Argentina catalogue, except that where asterisks are shown errors in the original printed catalogue have been corrected and the originally published values are stated in the notes. Two publications state corrections to the printed Uranometria Argentina. These are by B.A. Gould, Astronomische Nachrichten 116, 379-382 (1887AN....116..379G), and by T. W. Backhouse, Astronomical Journal 12, 112 (1892AJ.....12Q.112B). All of these, and a few others, mostly typographical misprints found by the present author, are presented in this digital version.

Stephen's Guide to the Logical Fallacies  

NSDL National Science Digital Library

Stephen Downes, an information architect with a background in philosophy, created this site with the aim of identifying, indexing, and describing "all known logical fallacies." A logical fallacy can be defined as an error in reasoning in which a conclusion appears to follow from a set of premises but in reality does not. Downes groups the fallacies into thirteen categories, such as Fallacies of Distraction, Inductive Fallacies, and Syllogistic Errors. Each fallacy (over 50 in all) is described with its name, definition, examples of how it might be used in an argument, and how the argument can be proven fallacious. The How to Use this Guide section of the site provides a helpful introduction, and a robust bibliography offers possibilities for further study of logic. In addition, users may register at the site (no fee) to gain access to discussion boards on the topic. The author notes that his Guide "is intended to help you in your own thinking, not to help you demolish someone else's argument." Regardless of how a reader uses the information, however, the site remains an interesting and fun investigation of how logical arguments are constructed.

Stephen FosterâÂÂs Sketchbook  

NSDL National Science Digital Library

Raised in and around Pittsburgh during the 19th century, Stephen Foster grew up singing in an all-male secret club and receiving some modest musical training from a local German immigrant, Henry Kleber. He soon became intensely interested in song-writing, and his first published song, âÂÂOpen Thy Lattice LoveâÂÂ, appeared when he was 18. Of course, he went on to write around 285 songs, including such old chestnuts as âÂÂBeautiful DreamerâÂÂ, âÂÂCamptown RacesâÂÂ, and of course âÂÂOh! SusannaâÂÂ. The University of PittsburghâÂÂs Digital Library has digitized his sketchbook and placed it online for the general web-browsing public. Visitors can search the sketchbook by song title, or simply browse the pages at their leisure. There are a number of real finds here, including drafts of âÂÂWhile the Bowl Goes Roundâ and âÂÂThou Art the Queen of My SongâÂÂ.

Initial Highlights from the Herschel Gould Belt Survey  

NASA Astrophysics Data System (ADS)

The Herschel Space Observatory provides a unique opportunity to improve our global un-derstanding of the earliest phases of star formation. I will present an overview of the first results from the Gould Belt survey (cf. http://gouldbelt-herschel.cea.fr/), one of the largest key projects with Herschel. The immediate objective of this SPIRE/PACS imaging survey is to obtain complete samples of nearby prestellar cores and Class 0 protostars with well char-acterized luminosities, temperatures, and density profiles, as well as robust core mass func-tions and protostar luminosity functions, in a variety of star-forming environments. Thanks to its high sensitivity and large spatial dynamic range, this survey can also probe, for the first time, the link between diffuse cirrus-like structures and compact self-gravitating cores. The main scientific goal is to elucidate the physical mechanisms responsible for the formation of prestellar cores out of the diffuse interstellar medium, crucial for understanding the origin of the stellar initial mass function. The first results, obtained toward the Aquila Rift and Polaris Flare regions during the 'Science Demonstration Phase' (SDP), are very promising (cf. http://herschel.esac.esa.int/SDPw kshops/presentations/IR/25A ndreG ouldBeltS DP 2009.pdf ).Basedonth

Uranium occurrences on the Blue Jay Claim, White Signal District, Grant County, New Mexico  

USGS Publications Warehouse

A discovery of secondary uranium minerals on the Blue Jay claim was reported in 1949 and the occurrence was examined by the authors in March 1950, The Blue Jay claim is about three-fourths of a mile south of White Signal, Grant County, N. Mex. in sees, 23 and 26, T. 20 3., R. 15 W. , New Mexico principal meridian. The Blue Jay claim is underlain by a pre-Cambrian granite mass that was intruded by numerous dikes ranging from rhyolite to basalt in composition. Abnormal radioactivity and secondary uranium minerals occur in altered rocks near oxidized quart z-pyrite veins. Forty-four samples ranged in grade from 0.001 to 0.11 percent uranium. The intermediate and basic rocks seem to have been the more favorable host rocks for the deposition of secondary uranium minerals, possibly because of their higher phosphate content.

No evidence of temporal preferences in caching by Western scrub-jays (Aphelocoma californica)?  

PubMed Central

Humans and other animals often favour immediate gratification over long-term gain. Primates, including humans, appear more willing to wait for rewards than other animals, such as rats or pigeons. Another group displaying impressive patience are the corvids, which possess large brains and show sophisticated cognitive abilities. Here, we assess intertemporal choice in one corvid species, the Western scrub-jay (Aphelocoma californica). These birds cache food for future consumption and respond flexibly to future needs. Cache-theft and cache-degradation are time-dependent processes in scrub-jay ecology that might necessitate sensitivity to delays between caching and retrieval. We adopt a caching paradigm with delays of up to 49 h. Across two experiments we find no evidence of a preference for earlier recovery. We highlight the possibility that, although scrub-jays can discriminate between the present and the future, they may not understand how far into the future an event will occur.

Radio-Loud and Radio-Quiet Gamma-Ray Pulsars from the Galactic Plane and the Gould Belt  

SciTech Connect

We present recent results of a pulsar population synthesis study in the polar cap model that includes the Parkes Multibeam Pulsar Survey, realistic beam geometries for radio and {gamma}-ray emission from neutron stars born in the Galactic disc as well as the local Gould Belt. We include nine radio surveys to normalize the simulated results from the Galactic disc to the number of radio pulsars observed by the group of selected surveys. In normalizing the contribution of the Gould Belt, we use results from a recent study that indicates a supernova rate in the Gould Belt of 3 to 5 times that of the local region of the Galactic plane leading to {approx}100 neutron stars born in the Gould Belt during the last 5 Myr. Our simulations include the dynamical evolution of the Gould Belt where neutron stars are produced in the plane of the Gould Belt during the past 5 Myr. We discuss the simulated numbers of radio-quiet (those below flux threshold of radio surveys) and radio-loud, {gamma}-ray pulsars from the Galactic disc and the Gould belt observed by {gamma}-ray telescopes EGRET, AGILE and GLAST. They suggest that about 35 of the unidentified EGRET sources could be (mostly radio-loud) {gamma}-ray pulsars with 2/3 of them born in the Galactic disc and 1/3 in the Gould Belt.

A New Population Estimate for the Florida Scrub Jay on Merritt Island National Wildlife Refuge  

NASA Technical Reports Server (NTRS)

The variable circular plot method was used to sample avifauna within different vegetation types determined from aerial imagery. The Florida Scrub Jay (Aphelocoma coerulescens coerulescens) population was estimated to range between 1,415 and 3,603 birds. Approximately half of the scrub and slash pine habitat appeared to be unused by Florida Scrub Jay, probably because the slash pine cover was too dense or the oak cover was too sparse. Results from the study suggest that the entire state population may be much lower than believed because the size of two of the three largest populations may have been overestimated.

Could the Unidentified EGRET Sources in the Gould Belt be of Pulsar Origin?  

NASA Technical Reports Server (NTRS)

We explore the possibility, within the polar cap model, that at least some of the recently identified new population of Energetic Gamma-Ray Experiment Telescope (EGRET) sources in the Gould Belt sources are gamma-ray pulsars, viewed at large angles to the magnetic axis, such that the line-of-sight misses both the bright gamma-ray double cone and the radio beam. We estimate that the detectability of such off-beam gamma-ray sources is about a factor of 4-5 times higher than that of the on-beam sources. The off-beam gamma-ray pulsars also have a faint, soft nature, which is consistent with the observed properties of the Gould Belt sources. We conclude that at least some of the middle latitude sources might be such off-beam gamma-ray pulsars if they are indeed in the Gould Belt.

Herschel Observations of Gould Belt Cores and Filaments  

NASA Astrophysics Data System (ADS)

The Herschel Space Observatory has provided us with unprecedented images of the initial and boundary conditions of the star formation process at far-infrared and submillimeter wavelengths. In particular, the Herschel data give key insight into the global properties of dense cores and the link between these properties and the structure of molecular clouds. I will give an overview of the results obtained in this area as part of the Herschel Gould Belt survey, one of the largest key projects with Herschel. The survey findings confirm the existence of a close relationship between the prestellar core mass function (CMF) and the stellar initial mass function (IMF). The Herschel images also reveal a rich network of filaments in every interstellar cloud and suggest an intimate connection between the filamentary structure of the ISM and the core formation process. Remarkably, filaments are omnipresent even in unbound, non-star-forming complexes and seem to be characterized by a narrow distribution of widths around ~ 0.1 pc, which roughly corresponds to the maximum observed size of prestellar cores. In active star-forming regions, most of the prestellar cores identified with Herschelare located within gravitationally unstable filaments above a critical threshold ~ 16 Msun/pc in mass per unit length, corresponding to Av ~ 8 in visual extinction or column density. Altogether, the Herschel results favor a scenario in which interstellar filaments and prestellar cores represent two fundamental steps in the star formation process: First, the dissipation of kinetic energy in large-scale MHD flows (turbulent or not) generates a complex web of filaments in the cold ISM; second, the densest filaments grow and fragment into prestellar cores (and ultimately protostars) by gravitational instability.

Level II scour analysis for Bridge 1 (JAY-TH00040001) on Town Highway 4, crossing Crook Brook, Jay, Vermont  

USGS Publications Warehouse

This report provides the results of a detailed Level II analysis of scour potential at structure JAY-TH00040001 on Town Highway 4 crossing Crook Brook, Jay, Vermont (figures 1–8). A Level II study is a basic engineering analysis of the site, including a quantitative analysis of stream stability and scour (U.S. Department of Transportation, 1993). Results of a Level I scour investigation also are included in Appendix E of this report. A Level I investigation provides a qualitative geomorphic characterization of the study site. Information on the bridge, gleaned from Vermont Agency of Transportation (VTAOT) files, was compiled prior to conducting Level I and Level II analyses and is found in Appendix D. The site is in the Green Mountain section of the New England physiographic province in northern Vermont. The 20.7-mi2 drainage area is in a predominantly rural and forested basin. In the vicinity of the study site, the surface cover is thick woody vegetation and/or forest except for the upstream right bank and overbank which is pasture. In the study area, Crook Brook has an incised, sinuous channel with a slope of approximately 0.02 ft/ft, an average channel top width of 86 ft and an average bank height of 6 ft. The channel bed material ranges from gravel to boulder with a median grain size (D50) of 48.7 mm (0.160 ft). The geomorphic assessment at the time of the Level I and Level II site visit on June 5, 1995, indicated that the reach was stable. The Town Highway 4 crossing of Crook Brook is a 49-ft-long, two-lane bridge consisting of one 45-foot concrete span (Vermont Agency of Transportation, written communication, March 6, 1995). The opening length of the structure parallel to the bridge face is 42 ft.The bridge is supported by vertical, concrete abutments with wingwalls. The channel is skewed approximately 5 degrees to the opening. The opening-skew-to-roadway is also 5 degrees. Channel scour is present along the left abutment. The scoured area was 1.5 ft deeper than the mean thalweg depth during the Level I assessment. Scour countermeasures include type-2 stone fill (less than 36 inches diameter) on the upstream and downstream sides of the left road embankment and at the upstream end of the left abutment. There is type-3 stone fill (less than 48 inches diameter) along the base of the upstream left wingwall. Additional details describing conditions at the site are included in the Level II Summary and Appendices D and E. Scour depths and recommended rock rip-rap sizes were computed using the general guidelines described in Hydraulic Engineering Circular 18 (Richardson and others, 1995). Total scour at a highway crossing is comprised of three components: 1) long-term streambed degradation; 2) contraction scour (due to accelerated flow caused by a reduction in flow area at a bridge) and; 3) local scour (caused by accelerated flow around piers and abutments). Total scour is the sum of the three components. Equations are available to compute depths for contraction and local scour and a summary of the results of these computations follows. Contraction scour for all modelled flows ranged from 2.5 to 3.8 ft. The worst-case contraction scour occurred at the 500-year discharge. Abutment scour at the left abutment ranged from 15.4 to 18.5 ft. Abutment scour at the right abutment ranged from 12.3 to 15.3 ft. The worst-case abutment scour occurred at the 500-year discharge for both abutments. Additional information on scour depths and depths to armoring are included in the section titled “Scour Results”. Scoured-streambed elevations, based on the calculated scour depths, are presented in tables 1 and 2. A cross-section of the scour computed at the bridge is presented in figure 8. Scour depths were calculated assuming an infinite depth of erosive material and a homogeneous particle-size distribution. It is generally accepted that the Froehlich equation (abutment scour) gives “excessively conservative estimates of scour depths” (Richardson and others, 1995, p. 47). Usually, computed scour depths are evaluated in combination

Obituary: Andrew Stephen Wilson, 1947-2008  

NASA Astrophysics Data System (ADS)

On 24 May 2008, Andrew Stephen Wilson passed away at the age of 61, in his home in Silver Spring, Maryland, from complications resulting from a painful spinal illness. Andrew was arguably one of the first truly multi-wavelength astronomers of his generation. His scientific work on active galactic nuclei [AGN] spanned the entire electromagnetic spectrum from the radio to the X-rays. Andrew was born in Doncaster, Yorkshire, England, on 26 March 1947. He was the younger of two brothers whose births were separated by the Second World War. His father, Norman, came from a relatively affluent family who were coal merchants. His mother, Mary, came from a less comfortable background, one of seven children, daughter of a skilled cabinet maker/French polisher, who went through a very hard time during the depression. As a teacher, she placed enormous value on hard work and education as a way of gaining advancement in life. When Andrew was four, the family moved to Skipton, a nice market town in the Yorkshire dales. Andrew went to a small village school until age eleven when he entered Ermysted's Grammar School. He was an enthusiastic soccer and cricket player. He never lost his enthusiasm for soccer and supported the local soccer team, Leeds United, for all his life. Andrew also followed the Yorkshire county cricket team. Andrew's interest in astronomy stemmed from the fact that at Ermysted's Grammar School someone donated a four-inch refracting telescope, so he and his friends used to go back in the evenings to investigate the rings of Saturn, the moons of Jupiter, and various nebulae. While an undergraduate at Cambridge, Andrew joined the astronomy club and ground an 8-inch mirror by hand as a part of a telescope that he set up in the backyard of his parents' house. Andrew spent hours observing with this telescope, and it was the wonder of the family. At Cambridge, Andrew obtained his bachelor's degree with first-class honors in 1969. During a short visit in London with his fellow students to celebrate the end of their exams, Andrew met Finnish summer student, Kaija Kettunen, whom he married in 1975 in her home town of Lieksa, Finland. They had a son, Daniel, now living in South Riding, Virginia, and a daughter, Caroline, living in Oakland, California. In 1973, Andrew obtained his doctorate degree in physics at the Cavendish Laboratory, working under the direction of Martin Ryle, winner of the 1974 Nobel Prize in physics. Andrew's PhD was dedicated to a study of the Crab Nebula at the highest radio frequencies at which the Cambridge One-mile Telescope could operate. This work, which included both intensity and polarization data, was a triumph of perseverance and skill in the reduction of an extremely complex data set. This experience stood him in excellent stead for his future career. After his PhD, Andrew went on to be a postdoctoral research fellow at Sterrewacht, Leiden, Netherlands, and then at the Astronomy Centre of the University of Sussex, England. By that time, Andrew wanted to leave England, because he thought that he would be able to secure a permanent position in astronomy faster in another country. He also loved traveling and getting to know other cultures, and he learned foreign languages easily. In 1978, Andrew and his wife had two choices: One was to accept a position at the European Southern Observatory in Garching and the other was to come to the University of Maryland. Together they decided to come to the United States rather than go to Germany because of the language and culture. Andrew remained at the University of Maryland for his entire career. He was a scientist of extraordinary productivity and impact over his lifetime: He wrote more than three-hundred scientific publications and accumulated more than 11,000 citations to this large body of work. In the 1970s and 1980s, he pioneered the use of radio telescopes for the study of active galactic nuclei, writing in collaboration with his students a number of seminal papers that are still standard references in the field today. In the last 15 years, Andrew becam

SR-71 Pilot Stephen (Steve) D. Ishmael  

NASA Technical Reports Server (NTRS)

NASA research pilot Stephen D. Ishmael is pictured here in front of an SR-71 Blackbird on the ramp at the Dryden Flight Research Center, Edwards, California. Ishmael was one of two NASA research pilots assigned to the SR-71 high speed research program in the early 1990s at NASA's Dryden Flight Research Facility (redesignated the Dryden Flight Research Center in 1994), Edwards, California. Ishmael became a NASA research pilot in 1977. Data from the SR-71 program will be used to aid designers of future supersonic aircraft and propulsion systems. Two SR-71 aircraft have been used by NASA as testbeds for high-speed and high-altitude aeronautical research. The aircraft, an SR-71A and an SR-71B pilot trainer aircraft, have been based here at NASA's Dryden Flight Research Center, Edwards, California. They were transferred to NASA after the U.S. Air Force program was cancelled. As research platforms, the aircraft can cruise at Mach 3 for more than one hour. For thermal experiments, this can produce heat soak temperatures of over 600 degrees Fahrenheit (F). This operating environment makes these aircraft excellent platforms to carry out research and experiments in a variety of areas -- aerodynamics, propulsion, structures, thermal protection materials, high-speed and high-temperature instrumentation, atmospheric studies, and sonic boom characterization. The SR-71 was used in a program to study ways of reducing sonic booms or over pressures that are heard on the ground, much like sharp thunderclaps, when an aircraft exceeds the speed of sound. Data from this Sonic Boom Mitigation Study could eventually lead to aircraft designs that would reduce the 'peak' overpressures of sonic booms and minimize the startling affect they produce on the ground. One of the first major experiments to be flown in the NASA SR-71 program was a laser air data collection system. It used laser light instead of air pressure to produce airspeed and attitude reference data, such as angle of attack and sideslip, which are normally obtained with small tubes and vanes extending into the airstream. One of Dryden's SR-71s was used for the Linear Aerospike Rocket Engine, or LASRE Experiment. Another earlier project consisted of a series of flights using the SR-71 as a science camera platform for NASA's Jet Propulsion Laboratory in Pasadena, California. An upward-looking ultraviolet video camera placed in the SR-71's nosebay studied a variety of celestial objects in wavelengths that are blocked to ground-based astronomers. Earlier in its history, Dryden had a decade of past experience at sustained speeds above Mach 3. Two YF-12A aircraft and an SR-71 designated as a YF-12C were flown at the center between December 1969 and November 1979 in a joint NASA/USAF program to learn more about the capabilities and limitations of high-speed, high-altitude flight. The YF-12As were prototypes of a planned interceptor aircraft based on a design that later evolved into the SR-71 reconnaissance aircraft. Dave Lux was the NASA SR-71 project manger for much of the decade of the 1990s, followed by Steve Schmidt. Developed for the USAF as reconnaissance aircraft more than 30 years ago, SR-71s are still the world's fastest and highest-flying production aircraft. The aircraft can fly at speeds of more than 2,200 miles per hour (Mach 3+, or more than three times the speed of sound) and at altitudes of over 85,000 feet. The Lockheed Skunk Works (now Lockheed Martin) built the original SR-71 aircraft. Each aircraft is 107.4 feet long, has a wingspan of 55.6 feet, and is 18.5 feet high (from the ground to the top of the rudders, when parked). Gross takeoff weight is about 140,000 pounds, including a possible fuel weight of 80,280 pounds. The airframes are built almost entirely of titanium and titanium alloys to withstand heat generated by sustained Mach 3 flight. Aerodynamic control surfaces consist of all-moving vertical tail surfaces, ailerons on the outer wings, and elevators on the trailing edges between the engine exhaust nozzles. The two SR-71s at Dryden have been assigned the follow

Exploring Stephen Krashen's "i+1" Acquisition Model in the Classroom

Stephen Krashen's theories can appear "seductive" to teachers of languages, in that they identify a seemingly clear way forward for language acquisition in the classroom. However, reification of Krashen's theories, in particular the notion of attaining "i+1" through comprehensible input, is demonstrated to be problematic. Based on empirical data…

Teaching the Classics: The Origin of Species as a Case Study  

NASA Astrophysics Data System (ADS)

Many (including the author) argue that reading the classics in the field should be part of a scientist's education. However, how you read the classics can be very different depending on whether you read them as a historian or as a practicing scientist. This point will be made by comparing two readings of Charles Darwin's Origin of Species, and by looking at the use that Stephen Jay Gould made of the history of science in his quest to promote his scientific ideas.

Avian Theory of Mind and counter espionage by food-caching western scrub-jays (Aphelocoma californica)

Food-caching scrub-jays hide food for future consumption and rely on memory to recover their caches at a later date. These caches are susceptible to pilfering by other individuals, however. Consequently, jays engage in a number of counter-strategies to protect their hidden items, caching most of them behind barriers, or using shade and distance as a way of reducing what the

Responses of small rodents to habitat restoration and management for the imperiled Florida Scrub-Jay  

Microsoft Academic Search

Debate about the relative merits of single-species management versus more comprehensive approaches has intensified in recent years. In east-central Florida, USA, land managers use prescribed burns and mechanical cutting to manage and restore scrub habitat to benefit the imperiled Florida Scrub-Jay (Aphelocoma coerulescens). However, these land-management techniques may affect non-target taxa, especially the threatened southeastern beach mouse (Peromyscus polionotus niveiventris).

Western scrub-jays allocate longer observation time to more valuable information.  

PubMed

When humans mentally reconstruct past events and imagine future scenarios, their subjective experience of mentally time travelling is accompanied by the awareness of doing so. Despite recent popularity of studying episodic memory in animals, such phenomenological consciousness has been extremely difficult to demonstrate without agreed behavioural markers of consciousness in non-linguistic subjects. We presented western scrub-jays (Aphelocoma californica) with a task requiring them to allocate observing time between two peepholes to see food being hidden in either of two compartments, one where observing the hiding location was necessary to later relocate the food, and another where food could easily be found without watching. Jays first separately experienced these consequences of possessing information in each compartment and subsequently, once given a choice, made more looks and spent more time looking into the compartment where information was necessary than into the compartment where it was unnecessary. Thus, the jays can collect information to solve a future problem. Moreover, they can differentiate sources of information according to their potential value and modify behaviour to efficiently collect important, usable information. This is the first evidence of metacognition in a species that passes the behavioural criteria for both retrospective and prospective mental time travel. PMID:24322875

First Results from the Herschel Gould Belt Survey in Taurus and Comparison with Other Clouds  

NASA Astrophysics Data System (ADS)

The unparalleled sensitivity and mapping speed of the ESA Herschel Space Observatory makes it possible to now map entire star formation regions in the time it would once have taken to map a single prestellar core. The Herschel Gould Belt Survey is a key program designed to fully map the clouds of the Gould Belt at five wavelengths between 70 and 500 ?m. These clouds span a range of physical conditions from the sterility of Polaris to the active cluster forming complexes of Orion and Aquila. These clouds allow us to examine the genesis of the core mass function and how the history of star formation in different regions varies. The early results have demonstrated the markedly different populations of cores in these regions and have revealed the nearly ubiquitous relationship of those cores with dense filaments.

The Gould's Belt Very Large Array Survey. III. The Orion Region  

NASA Astrophysics Data System (ADS)

We present results from a high-sensitivity (60 ?Jy), large-scale (2.26 deg2) survey obtained with the Karl G. Jansky Very Large Array as part of the Gould's Belt Survey program. We detected 374 and 354 sources at 4.5 and 7.5 GHz, respectively. Of these, 148 are associated with previously known young stellar objects (YSOs). Another 86 sources previously unclassified at either optical or infrared wavelengths exhibit radio properties that are consistent with those of young stars. The overall properties of our sources at radio wavelengths such as their variability and radio to X-ray luminosity relation are consistent with previous results from the Gould's Belt Survey. Our detections provide target lists for follow-up Very Long Baseline Array radio observations to determine their distances as YSOs are located in regions of high nebulosity and extinction, making it difficult to measure optical parallaxes.

Laboratory observations of electron energization and associated lower-hybrid and Trivelpiece-Gould wave turbulence during magnetic reconnection  

SciTech Connect

This work presents an experimental study of current-driven turbulence in a plasma undergoing magnetic reconnection in a low-beta, strong-guide-field regime. Electrostatic fluctuations are observed by small, high-bandwidth, and impedance-matched Langmuir probes. The observed modes, identified by their characteristic frequency and wavelength, include lower-hybrid fluctuations and high-frequency Trivelpiece-Gould modes. The observed waves are believed to arise from electrons energized by the reconnection process via direct bump-on-tail instability (Trivelpiece-Gould) or gradients in the fast electron population (lower-hybrid).

Efficacy of Three Vaccines in Protecting Western Scrub-Jays (Aphelocoma californica) from Experimental Infection with West Nile Virus: Implications for Vaccination of Island Scrub-Jays (Aphelocoma insularis)  

PubMed Central

Abstract The devastating effect of West Nile virus (WNV) on the avifauna of North America has led zoo managers and conservationists to attempt to protect vulnerable species through vaccination. The Island Scrub-Jay (Aphelocoma insularis) is one such species, being a corvid with a highly restricted insular range. Herein, we used congeneric Western Scrub-Jays (Aphelocoma californica) to test the efficacy of three WNV vaccines in protecting jays from an experimental challenge with WNV: (1) the Fort Dodge West Nile-Innovator® DNA equine vaccine, (2) an experimental DNA plasmid vaccine, pCBWN, and (3) the Merial Recombitek® equine vaccine. Vaccine efficacy after challenge was compared with naïve and nonvaccinated positive controls and a group of naturally immune jays. Overall, vaccination lowered peak viremia compared with nonvaccinated positive controls, but some WNV-related pathology persisted and the viremia was sufficient to possibly infect susceptible vector mosquitoes. The Fort Dodge West Nile-Innovator DNA equine vaccine and the pCBWN vaccine provided humoral immune priming and limited side effects. Five of the six birds vaccinated with the Merial Recombitek vaccine, including a vaccinated, non-WNV challenged control, developed extensive necrotic lesions in the pectoral muscle at the vaccine inoculation sites, which were attributed to the Merial vaccine. In light of the well-documented devastating effects of high morbidity and mortality associated with WNV infection in corvids, vaccination of Island Scrub-Jays with either the Fort Dodge West Nile-Innovator DNA vaccine or the pCBWN vaccine may increase the numbers of birds that would survive an epizootic should WNV become established on Santa Cruz Island.

Diocotron and Trivelpiece-Gould mode behavior in toroidal electron plasma  

NASA Astrophysics Data System (ADS)

Electron plasma confined in a purely toroidal magnetic field supports analogs of the electrostatic normal modes observed in cylindrical traps - namely diocotron and Trivelpiece-Gould waves. The Lawrence Non-neutral Torus II (LNT II) device is used to study such waves. Electron plasma with densities in the range of 107 cm-3 persisting for about 1 second are produced in LNT II with high vacuum conditions (<10-9 Torr), a toroidal magnetic field magnitude up to 550 G. The plasma is diagnosed by monitoring image charge flow to sectors of the symmetric conducting boundary (major radius of 18 cm and minor radius of 3.8 cm). Damping of the m=1 (k=0) diocotron mode is explored to assess the extent to which rotational and/or magnetic pumping transport mechanisms are operative in toroidal electron plasma. Resonant standing wave plasma modes (m=0) are excited in order to determine the Trivelpiece-Gould dispersion relation. This work is supported by the National Science Foundation Grant PHY-0812893.

Increased lifetime reproductive success for Siberian jay (Perisoreus infaustus) males with delayed dispersal  

PubMed Central

In a crowded environment the natal territory could serve as a haven for young and inexperienced offspring until a breeding vacancy emerges. Delayed dispersal and association with kin could then offer adaptive benefits through an individual fitness gain. Here we report that delayed dispersal is associated with a higher lifetime individual fitness in Siberian jay (Perisoreus infaustus) males. Sons bred more successfully and had more reproductive events in life when they delayed dispersal. The higher lifetime reproductive success when sons disperse later in life is sufficient to promote postponement of natal dispersal, suggesting that dispersal is delayed due to ecological constraints on access to high-quality habitats. We argue that the maintenance of this variation in the timing of dispersal and reproductive success can be reconciled with non-genetic mechanisms driving dispersal. Social dominance within broods reflecting environmental conditions during growth is such a mechanism.

A review of the experience gained in 10 years operation of Gould's solar industrial process heat system  

NASA Astrophysics Data System (ADS)

For nearly 10 years, the Gould Electronics, Incorporated manufacturing plant in Chandler, Arizona, has been a model of how medium-temperature solar thermal energy systems can produce economical industrial process heat (IPH). In 1982, a solar IPH system was designed and built on the site by Solar Kinetics, Inc. The system has remained in operation and continues to provide economical process heat for Gould's copper foil manufacturing operation. System performance and availability has fluctuated over the years, reaching a low point in early 1990 when the system was nearly inoperative because of equipment reliability problems. Gould teamed with engineers from Sandia National Laboratories' (Sandia) Solar Thermal Design Assistance Center to develop a plan to solve the technical problems and refurbish the field. The IPH system is currently operating at over 90-percent equipment availability, returning to Gould a net energy cost savings on the order of $7,500 per month. This paper presents the history and operation of the system from the perspective of the end user and describes the phased upgrade program undertaken with Sandia to refurbish the system.

Propagation of axisymmetric Trivelpiece-Gould mode along vortex columns generated by diocotron instability  

SciTech Connect

A high-frequency (HF) oscillation has been observed to propagate along magnetic field lines with an axisymmetric profile extending over multiple columns of magnetized pure electron plasma which undergo two-dimensional vortex motions. The observed frequency is a few hundred times higher than the rotation frequency of the vortices and varies in time as the density distribution of electrons deforms from an unstable hollow profile into vortex columns and approaches a single-peaked distribution. Experimental examinations reveal that the HF oscillation is excited by the gate pulse applied to prepare the initial profile and that the oscillation does not influence the subsequent dynamics of vortex columns. Further examinations including detailed observations and theoretical analyses indicate that the HF oscillation represents a profile-dependent eigenfunction of the Trivelpiece-Gould mode wave that consists of a dominant axisymmetric component and small fractions of higher azimuthal modes associated with the density distribution separated into columns.

We examine the global velocity structure of the non-outflowing gas, and calculate excitation temperatures and opacities. The large-scale mass and energetics of the region are evaluated, with special consideration for high-velocity gas. We find the cloud to have a mass of 203 M?, and to be gravitationally bound, and that the kinetic energy of the outflowing gas is approximately 70 per cent of the turbulent kinetic energy of the cloud. We identify compact outflows towards some of the submillimetre Class 0/I sources in the region.

Planck intermediate results. XII: Diffuse Galactic components in the Gould Belt system  

NASA Astrophysics Data System (ADS)

We perform an analysis of the diffuse low-frequency Galactic components in the southern part of the Gould Belt system (130° ? l ? 230° and -50° ? b ? -10°). Strong ultra-violet flux coming from the Gould Belt super-association is responsible for bright diffuse foregrounds that we observe from our position inside the system and that can help us improve our knowledge of the Galactic emission. Free-free emission and anomalous microwave emission (AME) are the dominant components at low frequencies (? < 40 GHz), while synchrotron emission is very smooth and faint. We separated diffuse free-free emission and AME from synchrotron emission and thermal dust emission by using Planck data, complemented by ancillary data, using the correlated component analysis (CCA) component-separation method and we compared our results with the results of cross-correlation of foreground templates with the frequency maps. We estimated the electron temperature Te from H? and free-free emission using two methods (temperature-temperature plot and cross-correlation) and obtained Te ranging from 3100 to 5200K for an effective fraction of absorbing dust along the line of sight of 30% (fd = 0.3). We estimated the frequency spectrum of the diffuse AME and recovered a peak frequency (in flux density units) of 25.5 ± 1.5 GHz. We verified the reliability of this result with realistic simulations that include biases in the spectral model for the AME and in the free-free template. By combining physical models for vibrational and rotational dust emission and adding the constraints from the thermal dust spectrum from Planck and IRAS, we are able to present a good description of the AME frequency spectrum for plausible values of the local density and radiation field.

Can male Eurasian jays disengage from their own current desire to feed the female what she wants?  

PubMed

Humans' predictions of another person's behaviour are regularly influenced by what they themselves might know or want. In a previous study, we found that male Eurasian jays (Garrulus glandarius) could cater for their female partner's current desire when sharing food with her. Here, we tested the extent to which the males' decisions are influenced by their own current desire. When the males' and female's desires matched, males correctly shared the food that was desired by both. When the female's desire differed from their own, the males' decisions were not entirely driven by their own desires, suggesting that males also took the female's desire into account. Thus, the male jays' decisions about their mates' desires are partially biased by their own desire and might be based upon similar processes as those found in humans. PMID:24671829

Uncertainty-based grade modelling of kimberlite: A case study of the Jay kimberlite pipe, EKATI Diamond Mine, Canada  

NASA Astrophysics Data System (ADS)

Understanding uncertainty in resource models is a significant requirement of mineral resource evaluation. Geostatistical simulation is one method that can be used to quantify uncertainty and Sequential Gaussian Simulation (SGS) is one of the easiest techniques to understand and implement. Using SGS provides both a spatial model of a given variable and the ranges around that variable at any number of scales. The Jay kimberlite pipe is located in the southeastern quadrant of the EKATI property. Drilling to date has identified three kimberlitic domains characterized by varying lithological properties. These domains are not separated by hard contacts, but rather by boundaries that are transitional. Within these domains, vertical trends exist; in particular, diamond grade increases with depth. For these reasons, Jay required an in-depth investigation of the best uncertainty-based grade modelling method to use. Grade was modelled by organic SGS and by using the stepwise conditional transform (SCT) to incorporate a trend into the simulation routine. Although the SGS results were valid, they did not fully reproduce the trend and therefore, the results did not fully match the geological interpretation of the deposit. The SCT results reproduced the trend, however, did not correspond to the variability of the data and therefore under-represented the actual uncertainty in the model. This was confirmed through detailed uncertainty calculation and probabilistic resource classification. Therefore, the SGS model was chosen as the preferred uncertainty-based grade model for the Jay pipe.

The Cultures and History of America: The Jay I. Kislak Collection at the Library of Congress  

NSDL National Science Digital Library

The Library of Congress has a number of important documents and historical items due to the kindness of persons who have amassed broad collections over the years, and then subsequently donated them for the use and consideration of the general public. One such gift is that which is profiled in this fine online collection. The Jay I. Kislak Collection includes a number of rare maps and books, and is largely focused around the early years of European exploration and early Florida, the Caribbean, and Mesoamerica. Moving through the collection, visitors can view a selection of these fine documents, including a 1493 transcription of Columbus's account of his 1492 voyage and a handbook for priests created by Dominicans working in the Guatemalan highlands. One real find on this site is the interactive presentation of the famed 1678 work, _The Buccaneers of America_. Through this presentation, visitors can listen along to a reading of various passages from this extremely dramatic account of Alexander Exquemelin (who is thought to be a French surgeon who worked with buccaneers) and view the pages of this original document.

Signaling for food and sex? Begging by reproductive female white-throated magpie-jays  

PubMed Central

Food begging is common in nutritionally dependent young of many animals, but structurally homologous calls recur in adult signal repertoires of many species. We propose eight functional hypotheses for begging in adults; these stem from observations in birds but apply broadly to other taxa in which begging occurs. Adult cooperatively-breeding white-throated magpie-jays (Calocitta formosa) use loud begging vocalizations, particularly near the nest site during reproduction. We analysed the social context and behavioural phenology of loud calling and allofeeding in this species and compared these with predictions from each functional hypothesis. We found that reproductive females are the primary producers of beg calls, and their begging peaks during the fertile period when reproductive conflict among males and females was highest. Loud begging rates correlated positively with provisioning rates, but females called more in the pre-incubation fertile period than after they initiated incubation. Based on the context, phenology and active space of the signal, we conclude that female loud begging vocalizations function to signal nutritional need to group members, but also have been evolutionarily co-opted to advertise fertility to potential extra-pair partners. The location of calling is likely a consequence of nest guarding by breeding females to prevent intraspecific brood parasitism.

Visual search and attention in blue jays (Cyanocitta cristata): Associative cuing and sequential priming.  

PubMed

Visual search for complex natural targets requires focal attention, either cued by predictive stimulus associations or primed by a representation of the most recently detected target. Because both processes can focus visual attention, cuing and priming were compared in an operant search task to evaluate their relative impacts on performance and to determine the nature of their interaction in combined treatments. Blue jays were trained to search for pairs of alternative targets among distractors. Informative or ambiguous color cues were provided before each trial, and targets were presented either in homogeneous blocked sequences or in constrained random order. Initial task acquisition was facilitated by priming in general, but was significantly retarded when targets were both cued and primed, indicating that the two processes interfered with each other during training. At asymptote, attentional effects were manifested mainly in inhibition, increasing latency in miscued trials and decreasing accuracy on primed trials following an unexpected target switch. A combination of cuing and priming was found to interfere with performance in such unexpected trials, apparently a result of the limited capacity of working memory. Because the ecological factors that promote priming or cuing are rather disparate, it is not clear whether they ever simultaneously contribute to natural predatory search.

Properties of interstellar filaments as revealed by the Herschel Gould Belt survey  

NASA Astrophysics Data System (ADS)

We present a scenario for filament formation and evolution motivated by recent observational results of nearby molecular clouds. The analysis of more than 270 filaments observed in 8 regions by the Herschel Gould Belt survey show that the filaments are characterized by a narrow distribution of central width sharply peaked at ˜0.1 pc. This typical filament width corresponds, within a factor of ˜ 2 to the sonic scale below which interstellar turbulence becomes subsonic, which may suggest that the filaments form as a result of the dissipation of large-scale turbulence. The analysis of IRAM 30m molecular line observations of a sample of these filaments show evidence of an increase in non-thermal velocity dispersion with column density which suggest an evolution of the supercritical filaments in mass per unit length while accreting surrounding material. Relative orientations of magnetic field lines and filamentary structures indicate that interstellar magnetic fields may play an important role in shaping the structure of, at least, some molecular clouds and help in channeling low-density material onto star forming filaments.

Growing evidence for a core formation threshold traced in Herschel Gould Belt survey clouds  

NASA Astrophysics Data System (ADS)

It has already been suggested that a threshold in column density - or in visual extinction - may need to be exceeded to form dense cores and then protostars. Based on Herschel Gould Belt survey results in the Aquila and Orion B molecular cloud complexes we observe clear connection between the locations of the detected prestellar cores and their background column density values. This finding appears to support a core formation scenario where such threshold corresponds to the extinction above which interstellar filaments become gravitationally unstable and fragment into cores. In these two actively star-forming regions we find the vast majority of the gravitationally bound prestellar cores above a high column density of about (6-7) × 1021 cm-2 (AV ˜ 6-7). This limit similarly appears in the column density probability distribution function (PDF) of the regions as well. The spatial distribution of the protostars and young stellar objects (YSOs) also shows a tight connection with the densest sites of both clouds, as more than 70 % of them appear above the mentioned AV thresholds. Herschel is an ESA space observatory with science instruments provided by European-led Principal Investigator consortia and with important participation from NASA.

The JCMT Legacy Survey of the Gould Belt: a first look at Orion B with HARP  

NASA Astrophysics Data System (ADS)

The Gould Belt Legacy Survey will survey nearby star-forming regions (within 500 pc), using Heterodyne Array Receiver Programme (HARP), Submillimetre Common-User Bolometer Array 2 and Polarimeter 2 on the James Clerk Maxwell Telescope. This paper describes the initial data obtained using HARP to observe 12CO, 13CO and C18O J = 3 -> 2 towards two regions in Orion B, NGC 2024 and NGC 2071. We describe the physical characteristics of the two clouds, calculating temperatures and opacities utilizing all the three isotopologues. We find good agreement between temperatures calculated from CO and from dust emission in the dense, energetic regions. We determine the mass and energetics of the clouds, and of the high-velocity material seen in 12CO emission, and compare the relative energetics of the high- and low-velocity material in the two clouds. We present a CLUMPFIND analysis of the 13CO condensations. The slope of the condensation mass functions, at the high-mass ends, is similar to the slope of the initial mass function.

The link between magnetic fields and filamentary clouds: bimodal cloud orientations in the Gould Belt  

NASA Astrophysics Data System (ADS)

The orientations of filamentary molecular clouds in the Gould Belt and their local intercloud media (ICM) magnetic fields are studied using near-infrared dust extinction maps and optical stellar polarimetry data. These filamentary clouds are a few-to-10 pc in length, and we find that their orientations tend to be either parallel or perpendicular to the mean field directions of the local ICM. This bimodal distribution is not found in cloud simulations with super-Alfvénic turbulence, in which the cloud orientations should be random. ICM magnetic fields that are dynamically important compared to inertial range turbulence and self-gravity can readily explain both field-filament configurations. Previous studies commonly recognize that strong magnetic fields can guide gravitational contraction and result in filaments perpendicular to them, but few discuss the fact that magnetic fields can also channel sub-Alfvénic turbulence to form filaments aligned with them. This strong-field scenario of cloud formation is also consistent with the constant field strength observed from ICM to clouds and is possible to explain the `hub-filament' cloud structure and the density threshold of cloud gravitational contraction.

Effects of fouling on the Japanese scallop Mizuhopecten yessoensis (Jay) in Peter the Great Bay (Sea of Japan)  

NASA Astrophysics Data System (ADS)

A valuable mariculture object, the Japanese scallop Mizuhopecten (= Patinopevten) yessoensis (Jay), after six hours long transportation by air and sowing on the bottom is fouled greater by epi- and endolythical organisms than the members of the native population. It is likely that the fouling negatively affects the specimens, those that were the largest before the sowing at the bottom were not found among those that reached puberty. The results of the effects of the endolythic polychaete Polydora brevipalpa and the barnacle Hesperibalanus hesperius on the growth rate of the Japanese scallop cultivated on the bottom of Peter the Great Bay (Sea of Japan) are provided in this paper.

Speciation in Western Scrub-Jays, Haldane's rule, and genetic clines in secondary contact  

PubMed Central

Background Haldane’s Rule, the tendency for the heterogametic sex to show reduced fertility in hybrid crosses, can obscure the signal of gene flow in mtDNA between species where females are heterogametic. Therefore, it is important when studying speciation and species limits in female-heterogametic species like birds to assess the signature of gene flow in the nuclear genome as well. We studied introgression of microsatellites and mtDNA across a secondary contact zone between coastal and interior lineages of Western Scrub-Jays (Aphelocoma californica) to test for a signature of Haldane’s Rule: a narrower cline of introgression in mtDNA compared to nuclear markers. Results Our initial phylogeographic analysis revealed that there is only one major area of contact between coastal and interior lineages and identified five genetic clusters with strong spatial structuring: Pacific Slope, Interior US, Edwards Plateau (Texas), Northern Mexico, and Southern Mexico. Consistent with predictions from Haldane’s Rule, mtDNA showed a narrower cline than nuclear markers across a transect through the hybrid zone. This result is not being driven by female-biased dispersal because neutral diffusion analysis, which included estimates of sex-specific dispersal rates, also showed less diffusion of mtDNA. Lineage-specific plumage traits were associated with nuclear genetic profiles for individuals in the hybrid zone, indicating that these differences are under genetic control. Conclusions This study adds to a growing list of studies that support predictions of Haldane’s Rule using cline analysis of multiple loci of differing inheritance modes, although alternate hypotheses like selection on different mtDNA types cannot be ruled out. That Haldane’s Rule appears to be operating in this system suggests a measure of reproductive isolation between the Pacific Slope and interior lineages. Based on a variety of evidence from the phenotype, ecology, and genetics, we recommend elevating three lineages to species level: A. californica (Pacific Slope); A. woodhouseii (Interior US plus Edwards Plateau plus Northern Mexico); A. sumichrasti (Southern Mexico). The distinctive Edwards Plateau population in Texas, which was monophyletic in mtDNA except for one individual, should be studied in greater detail given habitat threat.

The JCMT Legacy Survey of the Gould Belt: a first look at Taurus with HARP  

NASA Astrophysics Data System (ADS)

As part of a James Clerk Maxwell Telescope (JCMT) Legacy Survey of star formation in the Gould Belt, we present early science results for Taurus. CO J = 3 -2 maps have been secured along the north-west ridge and bowl, collectively known as L 1495, along with deep 13CO and C18O J = 3 -2 maps in two subregions. With these data, we search for molecular outflows, and use the distribution of flows, Herbig-Haro (HH) objects and shocked H2 line-emission features, together with the population of young stars, protostellar cores and starless condensations to map star formation across this extensive region. In total, 21 outflows are identified. It is clear that the bowl is more evolved than the ridge, harbouring a greater population of T Tauri stars and a more diffuse, more turbulent ambient medium. By comparison, the ridge contains a much younger, less widely distributed population of protostars which, in turn, is associated with a greater number of molecular outflows. We estimate the ratio of the numbers of pre-stellar to protostellar cores in L 1495 to be ~1.3-2.3, and of gravitationally unbound starless cores to (gravitationally bound) pre-stellar cores to be ~1. If we take previous estimates of the protostellar lifetime of ~5 × 105 yr, this indicates a pre-stellar lifetime of 9(+/-3) × 105 yr. From the number of outflows, we also crudely estimate the star formation efficiency in L 1495, finding it to be compatible with a canonical value of 10-15 per cent. We note that molecular outflow-driving sources have redder near-infrared colours than their HH jet-driving counterparts. We also find that the smaller, denser cores are associated with the more massive outflows, as one might expect if mass build-up in the flow increases with the collapse and contraction of the protostellar envelope.

A Search for Very Low Luminosity Objects in Gould Belt clouds  

NASA Astrophysics Data System (ADS)

We present the results of a search for Very Low Luminosity Objects (VeLLOs) in the Gould Belt clouds using infrared observations from 1.25 to 70 micron by the Spitzer Space Telescope and 2MASS. More than 140 VeLLO candidates were selected through the criteria by Dunham et al. and this study.The candidates were then tested if they are embedded in their gas envelopes as Galactic sources with observations of N2H+ (J=1-0), a high density tracer, and archival Herschel data. From this study 55 new candidate VeLLOs were discovered. We investigate the spatial distribution of all existing VeLLO candidates in the clouds, finding that about 49 % of sources are located within dense regions of the clouds while the remaining 51 % are outside the clouds. The VeLLOs within the clouds tend to have envelope masses of > 0.1 Msun while the sources outside clouds have masses of < 0.1 Msun, suggesting that their birth places are closely related to their envelope masses. We found that the numbers of YSOs and VeLLOs in all clouds are fairly well correlated. This indicates that the forming processes of the VeLLOs may be similar to those of normal stars.The bolometric luminosity and temperature of the VeLLO candidates are compared with predictions of episodic accretion models, showing that the low luminosities for most VeLLOs can be explained by their status in a quiescent phase between their episodic mass accretion. However, there are also a significant number of VeLLOs with very low envelope masses and lower luminosities than predicted by the episodic accretion models.They are likely either extragalactic contaminants or proto-brown dwarfs.

A Conservation Strategy for the Florida Scrub-Jay on John F. Kennedy Space Center/Merritt Island National Wildlife Refuge: An Initial Scientific Basis for Recovery  

NASA Technical Reports Server (NTRS)

The Florida Scrub-Jay (Aphelocoma coerulescens) is an indicator of ecosystem integrity of Florida scrub, an endangered ecosystem that requires frequent fire. One of the largest populations of this federally threatened species occurs on John F. Kennedy Space Center/Merritt Island National Wildlife Refuge. Population trends were predicted using population modeling and field data on reproduction and survival of Florida Scrub-Jays collected from 1988 - 1995. Analyses of historical photography indicated that habitat suitability has been declining for 30 years. Field data and computer simulations suggested that the population declined by at least 40% and will decline by another 40% in 1 0 years, if habitat management is not greatly intensified. Data and computer simulations suggest that habitat suitability cannot deviate greatly from optimal for the jay population to persist. Landscape trajectories of vegetation structure, responsible for declining habitat suitability, are associated with the disruption of natural fire regimes. Prescribed fire alone can not reverse the trajectories. A recovery strategy was developed, based on studies of Florida Scrub-Jays and scrub vegetation. A reserve design was formulated based on conservation science principles for scrub ecosystems. The strategy emphasizes frequent fire to restore habitat, but includes mechanical tree cutting for severely degraded areas. Pine thinning across large areas can produce rapid increases in habitat quality. Site-specific strategies will need to be developed, monitored, and modified to achieve conditions suitable for population persistence.

Star Formation in the Gould Belt: Star Formation Rates, Evolutionary Timescales, and Implications for Star Formation Theories  

NASA Astrophysics Data System (ADS)

Results from the c2d and Gould Belt Spitzer Legacy and Herschel Key Programs provide the most complete and accurate information on star formation in nearby molecular clouds. Complementary and follow-up studies add crucial information on the nature of star forming gas and the evolution of matter as it moves from core to disk to planets. The star formation rates and gas properties provide tests of star formation laws used by extragalactic researchers and of theories of large scale star formation. The durations in the stages of star formation (envelope infall, exposed star and disk, etc.) have been refined. The data are consistent with models in which accretion onto the forming star is episodic, with possible consequences for the initial conditions in planet-forming disks. The evolution of these disks, including dustsettling, volatile evolution, and gap-clearing, has been clarified.

Estuarine foraminiferal biofacies pattern compared to the brackish ichnofacies model: Port Stephens, southeast Australia  

NASA Astrophysics Data System (ADS)

Port Stephens, located in SE Australia, is a shallow estuary with an outer and inner basin separated by a narrow channel. Foraminiferal biofacies distribution reveals this complex physical environment. The flood-tide delta forms a transition between the wave-dominated open coast and the microtide-dominated estuary. Sand wave dynamics cause a shifting substrate, resulting in allochthonous assemblages of calcareous shelf species transported into the bay through a wide entrance. The muddy central basin is heavily bioturbated, and allows for an in-situ, mixed calcareous and agglutinated assemblage of a progressively more estuarine character. Burial of organic matter and increased bioturbation permits infaunal species to increase in abundance, but promotes calcium carbonate dissolution. The bayhead delta of the Karuah River is characterized by lithic-rich substrates that are associated with robust calcareous species. Tidal cycles, combined with low river-flux, provide nearly fully marine conditions far upstream into the Karuah River. Marginal regions, from sandy/muddy tidal flats to marsh, show distinct assemblages of opportunistic species that respond to tidal exposure, substrate variations, organic matter flux and salinities. Early diagenetic taphonomic loss, closely linked with bioturbation, needs to be considered in interpretations of microfossil assemblages. Foraminiferal biofacies analysis, in combination with the brackish-water ichnology model, is a powerful tool for recognizing Mesozoic marginal marine environments. Port Stephens, with its environmental complexity, offers a valuable modern analogue for estuarine deposits of the geological past.

Road load simulator tests of the Gould phase 1 functional model silicon controlled rectifier ac motor controller for electric vehicles  

NASA Technical Reports Server (NTRS)

The test results for a functional model ac motor controller for electric vehicles and a three-phase induction motor which were dynamically tested on the Lewis Research Center road load simulator are presented. Results show that the controller has the capability to meet the SAE-J227a D cycle test schedule and to accelerate a 1576-kg (3456-lb) simulated vehicle to a cruise speed of 88.5 km/hr (55 mph). Combined motor controller efficiency is 72 percent and the power inverter efficiency alone is 89 percent for the cruise region of the D cycle. Steady state test results for motoring, regeneration, and thermal data obtained by operating the simulator as a conventional dynamometer are in agreement with the contractor's previously reported data. The regeneration test results indicate that a reduction in energy requirements for urban driving cycles is attainable with regenerative braking. Test results and data in this report serve as a data base for further development of ac motor controllers and propulsion systems for electric vehicles. The controller uses state-of-the-art silicon controlled rectifier (SCR) power semiconductors and microprocessor-based logic and control circuitry. The controller was developed by Gould Laboratories under a Lewis contract for the Department of Energy's Electric and Hybrid Vehicle program.

THE SPITZER SURVEY OF INTERSTELLAR CLOUDS IN THE GOULD BELT. II. THE CEPHEUS FLARE OBSERVED WITH IRAC AND MIPS  

SciTech Connect

We present Spitzer Infrared Array Camera (IRAC; {approx}2 deg{sup 2}) and Multiband Imaging Photometer for Spitzer (MIPS; {approx}8 deg{sup 2}) observations of the Cepheus Flare, which is associated with the Gould Belt, at an approximate distance of {approx}300 pc. Around 6500 sources are detected in all four IRAC bands, of which {approx}900 have MIPS 24 {mu}m detections. We identify 133 young stellar object (YSO) candidates using color-magnitude diagram techniques, and a large number of the YSO candidates are associated with the NGC 7023 reflection nebula. Cross-identifications were made with the Guide Star Catalog II and the IRAS Faint Source Catalog, and spectral energy distributions (SEDs) were constructed. SED modeling was conducted to estimate the degree of infrared excess. It was found that a large majority of disks were optically thick accreting disks, suggesting that there has been little disk evolution in these sources. Nearest-neighbor clustering analysis identified four small protostellar groups (L1228, L1228N, L1251A, and L1251B) with 5-15 members each and the larger NGC 7023 association with 32 YSO members. The star-formation efficiency for cores with clusters of protostars and for those without clusters was found to be {approx}8% and {approx}1%, respectively. The cores L1155, L1241, and L1247 are confirmed to be starless down to our luminosity limit of L {sub bol} = 0.06 L {sub sun}.

The James Clerk Maxwell Telescope Legacy Survey of Nearby Star-forming Regions in the Gould Belt  

NASA Astrophysics Data System (ADS)

This paper describes a James Clerk Maxwell Telescope (JCMT) legacy survey that has been awarded roughly 500 hr of observing time to be carried out from 2007 to 2009. In this survey, we will map with SCUBA-2 (Submillimetre Common-User Bolometer Array 2) almost all of the well-known low-mass and intermediate-mass star-forming regions within 0.5 kpc that are accessible from the JCMT. Most of these locations are associated with the Gould Belt. From these observations, we will produce a flux-limited snapshot of star formation near the Sun, providing a legacy of images, as well as point-source and extended-source catalogs, over almost 700 deg2 of sky. The resulting images will yield the first catalog of prestellar and protostellar sources selected by submillimeter continuum emission, and should increase the number of known sources by more than an order of magnitude. We will also obtain with the array receiver HARP (Heterodyne Array Receiver Program) CO maps, in three CO isotopologues, of a large typical sample of prestellar and protostellar sources. We will then map the brightest hundred sources with the SCUBA-2 polarimeter (POL-2), producing the first statistically significant set of polarization maps in the submillimeter. The images and source catalogs will be a powerful reference set for astronomers, providing a detailed legacy archive for future telescopes, including ALMA, Herschel, and JWST.

Out of Gondwanaland; the evolutionary history of cooperative breeding and social behaviour among crows, magpies, jays and allies  

PubMed Central

Cooperative breeding is comparatively rare among birds in the mainly temperate and boreal Northern Hemisphere. Here we test if the distribution of breeding systems reflects a response to latitude by means of a phylogenetic analysis using correlates with geographical range among the corvids (crows, jays, magpies and allied groups). The corvids trace their ancestry to the predominantly cooperative ‘Corvida’ branch of oscine passerines from the Australo-Papuan region on the ancient Gondwanaland supercontinent, but we could not confirm the ancestral state of the breeding system within the family, while family cohesion may be ancestral. Initial diversification among pair-breeding taxa that are basal in the corvid phylogeny, represented by genera such as Pyrrhocorax and Dendrocitta, indicates that the corvid family in its current form could have evolved from pair-breeding ancestors only after they had escaped the Australo-Papuan shield. Within the family, cooperative breeding (alloparental care/family cohesion) is strongly correlated to latitude and its predominance in species maintaining a southerly distribution indicates a secondary evolution of cooperative breeding in the lineage leading away from the basal corvids. Multiple transitions show plasticity in the breeding system, indicating a response to latitude rather than evolutionary inertia. The evolutionary background to the loss of cooperative breeding among species with a northerly distribution is complex and differs between species, indicating a response to a variety of selection forces. Family cohesion where the offspring provide alloparental care is a main route to cooperatively breeding groups among corvids. Some corvid species lost only alloparental care, while maintaining coherent family groups. Other species lost family cohesion and, as a corollary, they also lost the behaviour where retained offspring provide alloparental care.

Congruent population structure inferred from dispersal behaviour and intensive genetic surveys of the threatened Florida scrub-jay (Aphelocoma c??rulescens)  

USGS Publications Warehouse

The delimitation of populations, defined as groups of individuals linked by gene flow, is possible by the analysis of genetic markers and also by spatial models based on dispersal probabilities across a landscape. We combined these two complimentary methods to define the spatial pattern of genetic structure among remaining populations of the threatened Florida scrub-jay, a species for which dispersal ability is unusually well-characterized. The range-wide population was intensively censused in the 1990s, and a metapopulation model defined population boundaries based on predicted dispersal-mediated demographic connectivity. We subjected genotypes from more than 1000 individual jays screened at 20 microsatellite loci to two Bayesian clustering methods. We describe a consensus method for identifying common features across many replicated clustering runs. Ten genetically differentiated groups exist across the present-day range of the Florida scrub-jay. These groups are largely consistent with the dispersal-defined metapopulations, which assume very limited dispersal ability. Some genetic groups comprise more than one metapopulation, likely because these genetically similar metapopulations were sundered only recently by habitat alteration. The combined reconstructions of population structure based on genetics and dispersal-mediated demographic connectivity provide a robust depiction of the current genetic and demographic organization of this species, reflecting past and present levels of dispersal among occupied habitat patches. The differentiation of populations into 10 genetic groups adds urgency to management efforts aimed at preserving what remains of genetic variation in this dwindling species, by maintaining viable populations of all genetically differentiated and geographically isolated populations. ?? 2008 The Authors.

Stephen Girard (1750-1831): a one-eyed American patriot.  

PubMed

Stephen Girard trader, banker, millionaire, and patriot lived 81 full and exciting years. Apparently born with a blind or amblyopic right eye, he emigrated from Bordeaux, France, via Santa Domingo to the United States, and finally settled in Philadelphia, where he developed a successful maritime trade. Ultimately, Girard became the first multimillionaire in the United States. Extremely generous, he often walked from his home in the center of Philadelphia to his farm in what is now South Philadelphia distributing shoes to needy children. Probably Girard's most heroic gestures were his gallant fight against the yellow fever epidemic in 1793 and his loan to the U.S. government during the War of 1812, which allowed the bankrupt country to continue the conflict and ultimately to win the war.

THE SPITZER SURVEY OF INTERSTELLAR CLOUDS IN THE GOULD BELT. V. OPHIUCHUS NORTH OBSERVED WITH IRAC AND MIPS  

SciTech Connect

We present Spitzer IRAC (2.1 deg{sup 2}) and MIPS (6.5 deg{sup 2}) observations of star formation in the Ophiuchus North (Oph N) molecular clouds. This fragmentary cloud complex lies on the edge of the Sco-Cen OB association, several degrees to the north of the well-known {rho} Oph star-forming region, at an approximate distance of 130 pc. The Oph N clouds were mapped as part of the Spitzer Gould Belt project under the working name 'Scorpius'. In the regions mapped, selected to encompass all the cloud with visual extinction A{sub V} > 3, 11 young stellar object (YSO) candidates are identified, 8 from IRAC/MIPS color-based selection and 3 from Two Micron All Sky Survey (2MASS) K{sub S} /MIPS colors. Adding to one source previously identified in L43, this increases the number of YSOcs identified in Oph N to 12. During the selection process, four color-based YSOcs were rejected as probable asymptotic giant branch stars and one as a known galaxy. The sources span the full range of YSOc classifications from Class 0/1 to Class III, and starless cores are also present. Twelve high extinction (A{sub V} > 10) cores are identified with a total mass of {approx}100 M{sub Sun }. These results confirm that there is little ongoing star formation in this region (instantaneous star formation efficiency <0.34%) and that the bottleneck lies in the formation of dense cores. The influence of the nearby Upper Sco OB association, including the 09V star {zeta} Oph, is seen in dynamical interactions and raised dust temperatures but has not enhanced levels of star formation in Oph N.

THE SPITZER SURVEY OF INTERSTELLAR CLOUDS IN THE GOULD BELT. IV. LUPUS V AND VI OBSERVED WITH IRAC AND MIPS  

SciTech Connect

We present Gould's Belt (GB) Spitzer IRAC and MIPS observations of the Lupus V and VI clouds and discuss them in combination with near-infrared (2MASS) data. Our observations complement those obtained for other Lupus clouds within the frame of the Spitzer 'Core to Disk' (c2d) Legacy Survey. We found 43 young stellar object (YSO) candidates in Lupus V and 45 in Lupus VI, including two transition disks, using the standard c2d/GB selection method. None of these sources was classified as a pre-main-sequence star from previous optical, near-IR, and X-ray surveys. A large majority of these YSO candidates appear to be surrounded by thin disks (Class III; {approx}79% in Lupus V and {approx}87% in Lupus VI). These Class III abundances differ significantly from those observed for the other Lupus clouds and c2d/GB surveyed star-forming regions, where objects with optically thick disks (Class II) dominate the young population. We investigate various scenarios that can explain this discrepancy. In particular, we show that disk photoevaporation due to nearby OB stars is not responsible for the high fraction of Class III objects. The gas surface densities measured for Lupus V and VI lie below the star formation threshold (A{sub V} {approx} 8.6 mag), while this is not the case for other Lupus clouds. Thus, few Myr older age for the YSOs in Lupus V and VI with respect to other Lupus clouds is the most likely explanation of the high fraction of Class III objects in these clouds, while a higher characteristic stellar mass might be a contributing factor. Better constraints on the age and binary fraction of the Lupus clouds might solve the puzzle but require further observations.

Test series 1: seismic-fragility tests of naturally-aged Class 1E Gould NCX-2250 battery cells  

SciTech Connect

The seismic-fragility response of naturally-aged, nuclear station, safety-related batteries is of interest for two reasons: (1) to determine actual failure modes and thresholds; and (2) to determine the validity of using the electrical capacity of individual cells as an indicator of the end-of-life of a battery, given a seismic event. This report covers the first test series of an extensive program using 12-year old, lead-calcium, Gould NCX-2250 cells, from the James A. Fitzpatrick Nuclear Power Station operated by the New York Power Authority. Seismic tests with three cell configurations were performed using a triaxial shake table: single-cell tests, rigidly mounted; multi-cell (three) tests, mounted in a typical battery rack; and single-cell tests specifically aimed towards examining propagation of pre-existing case cracks. In general the test philosophy was to monitor the electrical properties including discharge capacity of cells through a graduated series of g-level step increases until either the shake-table limits were reached or until electrical failure of the cells occurred. Of nine electrically active cells, six failed during seismic testing over a range of imposed g-level loads in excess of a 1-g ZPA. Post-test examination revealed a common failure mode, the cracking at the abnormally brittle, positive lead bus-bar/post interface; further examination showed that the failure zone was extremely coarse grained and extensively corroded. Presently accepted accelerated-aging methods for qualifying batteries, per IEEE Std. 535-1979, are based on plate growth, but these naturally-aged 12-year old cells showed no significant plate growth.

The Spitzer Survey of Interstellar Clouds in the Gould Belt. VI. The Auriga-California Molecular Cloud Observed with IRAC and MIPS  

NASA Astrophysics Data System (ADS)

We present observations of the Auriga-California Molecular Cloud (AMC) at 3.6, 4.5, 5.8, 8.0, 24, 70, and 160 ?m observed with the IRAC and MIPS detectors as part of the Spitzer Gould Belt Legacy Survey. The total mapped areas are 2.5 deg2 with IRAC and 10.47 deg2 with MIPS. This giant molecular cloud is one of two in the nearby Gould Belt of star-forming regions, the other being the Orion A Molecular Cloud (OMC). We compare source counts, colors, and magnitudes in our observed region to a subset of the SWIRE data that was processed through our pipeline. Using color-magnitude and color-color diagrams, we find evidence for a substantial population of 166 young stellar objects (YSOs) in the cloud, many of which were previously unknown. Most of this population is concentrated around the LkH? 101 cluster and the filament extending from it. We present a quantitative description of the degree of clustering and discuss the relative fraction of YSOs in earlier (Class I and F) and later (Class II) classes compared to other clouds. We perform simple SED modeling of the YSOs with disks to compare the mid-IR properties to disks in other clouds and identify 14 classical transition disk candidates. Although the AMC is similar in mass, size, and distance to the OMC, it is forming about 15-20 times fewer stars.

First use of halothane in the United States, C. Ronald Stephen, M.D. (1916-2006).  

PubMed

Anesthesia is one of the most valued discoveries in all of history. Almost immediately after the first public demonstration of ether anesthesia, a search for a better drug began. Ether, despite its flammability, persisted as the primary inhalation agent for over a hundred years. The breakthrough came with the introduction of a non-flammable volatile anesthetic called halothane in 1955. The drug was approved by the FDA in 1958 and quickly became the most commonly used agent in the United States. It was a quantum leap forward in the safety of anesthetic drugs. It became obsolete in 1988 because of hepatotoxicity. Three eminent anesthesiologists: Drs. Abajian of Vermont, Siker of Pittsburgh and Stephen of Duke could have been the first to use halothane in the USA. My review of the documents and writings of the three confirm that Dr. C. Ronald Stephen of Duke University was indeed the first to use and publish on halothane anesthesia in the USA. PMID:20506766

Abraham Lincoln loses a medical malpractice case, debates Stephen A. Douglas, and secures two murder acquittals.  

PubMed

An improperly healed fracture was the most common reason for the medical malpractice crisis between the 1830s and 1860s in the United States. As a practicing lawyer in Illinois, Abraham Lincoln defended physicians in medical malpractice law suits. One of these was Dr. Powers Ritchey, who was sued for malpractice in 1855. Lincoln agreed to represent Dr. Ritchey in 1858 as the case was appealed to the supreme court of Illinois. In the interim, Lincoln defended two indicted murderers and won acquittals for both. Between the two murder trials, Lincoln debated Stephen A. Douglas while running for U.S. Senator from Illinois. Lincoln believed that Ritchey's case was poorly represented in the lower court. Ritchey's prior attorneys did not file a bill of exceptions to the testimony of the plaintiff's expert medical witnesses. Lincoln attempted to rebut the allegation of a lack of reasonable medical care and diligence by Ritchey, and he sought to secure a new trial for his client. In its decision, the supreme court of Illinois did not find any error and affirmed the lower court's judgment. PMID:14768936

Genetic analysis of adult plant, quantitative resistance to stripe rust in wheat cultivar 'Stephens' in multi-environment trials.  

PubMed

The wheat (Triticum aestivum L.) cultivar 'Stephens' has been grown commercially in the USA Pacific Northwest for 30 years. The durable resistance of 'Stephens' to stripe rust (Puccinia striiformis f. sp. tritici) was believed to be due to a combination of seedling and adult plant resistance genes. Multilocation field trials, diversity array technology (DArT), and simple sequence repeat (SSR) markers were used to identify quantitative trait loci (QTL) for resistance. Recombinant inbred lines were assessed for stripe rust response in eight locations/years, five in 2008 and three in 2009. The data from Mt. Vernon, WA, differed from all other environments, and composite interval mapping (CIM) identified three QTL, QYrst.orr-1AL, QYrst.orr-4BS, and QYrpl.orr-6AL, which accounted for 12, 11, and 6% of the phenotypic variance, respectively. CIM across the remaining six environments identified four main QTL. Two QTL, QYrst.orr-2BS.2 and QYrst.orr-7AS, were detected in five of six environments and explained 11 and 15% of the phenotypic variance, respectively. Two other QTL, QYrst.orr-2AS and QYrpl.orr-4BL, were detected across four and three of six environments, and explained 19 and 9% of the phenotypic variance, respectively. The susceptible parent 'Platte' contributed QYrpl.orr-4BL and QYrpl.orr-6AL, with the remaining QTL originating from 'Stephens'. For each environment, additional minor QTL were detected, each accounting for 6-10% of the phenotypic variance. Different QTL with moderate effects were identified in both 'Stephens' and 'Platte'. Significant QTL × environment interactions were evident, suggesting that specificity to plant stage, pathogen genotype, and/or temperature was important. PMID:21912857

Depositional environments and diagenesis of lower Pennsylvanian Caddo Formation, Stephens County, Texas  

SciTech Connect

Since its discovery in 1916, the Lower Pennsylvanian Caddo limestone has been one of the most prolific producing intervals in the central Texas region. Favorable reservoir characteristics, with porosities from 9 to 24% and permeabilities from 0.1 to 1,000 md in the pay interval, have enabled many oil companies to initiate successful secondary recovery waterflood projects. Since its discovery, more than 200 million bbl of oil has been recovered from this formation in Stephens County alone. The Caddo reef trend developed during the Early Pennsylvanian, generally along the axis of the Bend flexure. Close examination of whole core and thin sections reveals the formation to be a series of small reef mounds characterized by wackestones. The wackestones consist of green algae, brachiopods, and some rugose corals, which are found on the leeward side (back reef). This sequence is commonly found in the top segment of the Caddo. Deeper into the formation the sequence grades into a packstone/wackestone, characteristic of an oceanward margin (fore reef), and is distinguished by red algae, foraminifera (fusulinids and miliolids), and crinoid hash. The basal sequence is a series of alternating lime mudstones and shales that are heavily silicified. Diagenesis is the key to reservoir rock quality. Moldic porosity was created through dissolution of organisms composed of low magnesium calcite (brachiopods) and aragonite (corals) during periods of subaerial exposure of the back reef. During this period of low sea level, fore-reef sediments were partly cemented by CaCO{sub 3} and were not subaerially exposed. Therefore, moldic porosity was not created in the fore-reef sediments. Porosity in the fore reef was later created in places by dissolution of this cement. Secondary dolomite was later precipitated along pore walls, and in places it occluded porosity in the pore spaces.

Geologic characterization of Caddo Limestone Reservoir, Curry Unit, Stephens County, north-central Texas  

SciTech Connect

Three classic carbonate models (carbonate bank, oolitic shoal, and tidal flat) are applied to interpret the depositional environments and diagenesis of the Caddo limestone (Middle Pennsylvanian). The study area is located in west-central Stephens County, approximately 4 mi southwest of Breckenridge, Texas. Phylloid algal mounds developed on a lower Caddo ramp, along the transition of the Concho platform and Fort Worth basin. Within the area defined as the Curry unit, phylloid algal mounds and intermound facies aggraded to sea level. This led to the development of an areally restricted carbonate bank. Some phylloid algal buildups underwent subaerial exposure, and fresh water leached unstable carbonate minerals, creating minor secondary porosity (<10%). An oolitic shoal (0-9.2 m thick) overlies and partially intergrades with the phylloid algal bank. Ooids were deposited along the margin of the preexisting bank, whereas fine-grained oolitic and peloidal packstone were deposited on the bank. The bank margin oolite exhibits oomoldic porosity in excess of 15%. The uppermost 6.1-24.4 m of the Caddo represents intertidal deposition. Sediment, primarily algal remains and carbonate mud, was deposited on a preexisting surface of ooids and peloids. Fenestral fabric. rhizoliths, brecciated zones, and small-scale channels are common features. A wide variety of pore types are present in the intertidal zone; intraskeletal, framework, biomoldic, and vuggy pores are most important. Throughout this zone, porosity exceeds 10% and permeability averages 12 md. The Curry unit has produced approximately 28 million bbl of oil (primary and secondary) from the upper Caddo. Depositional environments and diagenesis of the Caddo are complex. A greater understanding of these complexities may enable geoscientists to evaluate remaining future potential within the Caddo and in other similar carbonate accumulations.

Behaviour and stability of Trivelpiece-Gould modes in non-neutral plasma containing small density fraction of background gas ions  

NASA Astrophysics Data System (ADS)

It is shown that the frequencies of Trivelpiece-Gould (TG) modes in non-neutral plasma can get into the low-frequency range due to the Doppler shift caused by plasma rotation in crossed fields. TG modes interact with the ion modes that leads to plasma instability. In paper the frequency spectrum of "cold" electron plasma completely filling a waveguide and containing small density fraction of ions of background gas is determined numerically. For ions the kinetic description is used. Oscillations having azimuthal number m = 2 are considered. In this case both low- and upper-hybrid TG modes get into the low-frequency range. The spectrum consists of families of "modified" ion cyclotron (MIC) modes and electron TG modes with the frequencies equal to hybrid frequencies with the Doppler shift. The growth rates of upper-hybrid modes are much faster than the growth rates of low-hybrid and MIC modes.

Surveillance for West Nile Virus and Vaccination of Free-Ranging Island Scrub-Jays (Aphelocoma insularis) on Santa Cruz Island, California  

PubMed Central

Abstract Transmission of West Nile virus (WNV) on mainland California poses an ongoing threat to the island scrub-jay (ISSJ, Aphelocoma insularis), a species that occurs only on Santa Cruz Island, California, and whose total population numbers <5000. Our report describes the surveillance and management efforts conducted since 2006 that are designed to understand and mitigate for the consequences of WNV introduction into the ISSJ population. We suspect that WNV would most likely be introduced to the island via the movement of infected birds from the mainland. However, antibody testing of >750 migrating and resident birds on the island from 2006 to 2009 indicated that WNV had not become established by the end of 2009. Several species of competent mosquito vectors were collected at very low abundance on the island, including the important mainland vectors Culex tarsalis and Culex quinquefasciatus. However, the island was generally cooler than areas of mainland California that experienced intense WNV transmission, and these lower temperatures may have reduced the likelihood of WNV becoming established because they do not support efficient virus replication in mosquitoes. A vaccination program was initiated in 2008 to create a rescue population of ISSJ that would be more likely to survive a catastrophic outbreak. To further that goal, we recommend managers vaccinate >100 ISSJ each year as part of ongoing research and monitoring efforts.

Reproductive Ecology Of The Florida Scrub-Jay (Aphelocoma Coerulescens) On John F. Kennedy Space Center/Merritt Island National Wildlife Refuge: A Long-Term Study  

NASA Technical Reports Server (NTRS)

From 1988 to 2002 we studied the breeding ecology of Florida Scrub-Jays (Aphelocoma coerulescens) on John F. Kennedy Space Center/Merritt Island National Wildlife Refuge. We examined phenology, clutch size, hatching failure rates, fledgling production, nest success, predation rates, sources egg and nestling mortality, and the effects of helpers on these measures. Nesting phenology was similar among sites. Mean clutch size at Titan was significantly larger than at HC or T4. Pairs with helpers did not produce larger clutches than pairs without helpers. Fledgling production at T4 was significantly greater than at HC and similar to Titan. Pairs with helpers at HC produced significantly more fledglings than pairs without helpers; helpers did not influence fledgling production at the other sites. Nest success at HC and Titan was low, 19% and 32% respectively. Nest success at T4 was 48% and was significantly greater than at HC. Average predation rates at all sites increased with season progression. Predation rates at all sight rose sharply by early June. The main cause of nest failure at all sites was predation, 93%.

Paleontology at the "high table"? Popularization and disciplinary status in recent paleontology.  

PubMed

This paper examines the way in which paleontologists used "popular books" to call for a broader "expanded synthesis" of evolutionary biology. Beginning in the 1970s, a group of influential paleontologists, including Stephen Jay Gould, Niles Eldredge, David Raup, Steven Stanley, and others, aggressively promoted a new theoretical, evolutionary approach to the fossil record as an important revision of the existing synthetic view of Darwinism. This work had a transformative effect within the discipline of paleontology. However, by the 1980s, paleontologists began making their case to a wider audience, both within evolutionary biology, and to the general public. Many of their books-for example, Eldredge's provocatively-titled Unfinished Synthesis-explicitly argued that the received synthetic view of Darwinian evolution was incomplete, and that paleontological contributions such as punctuated equilibria, the hierarchical model of macroevolution, and the study of mass extinction dynamics offered a substantial corrective to evolutionary theory. This paper argues that books-far from being "mere popularizations" of scientific ideas-played an important role in disciplinary debates surrounding evolutionary theory during the 1980s, and in particular that paleontologists like Gould and Eldredge self-consciously adopted the book format because of the importance of that genre in the history of evolutionary biology.

HMGB in Mollusk Crassostrea ariakensis Gould: Structure, Pro-Inflammatory Cytokine Function Characterization and Anti-Infection Role of Its Antibody  

PubMed Central

Background Crassostrea ariakensis Gould is a representative bivalve species and an economically important oyster in China, but suffers severe mortalities in recent years that are caused by rickettsia-like organism (RLO). Prevention and control of this disease is a priority for the development of oyster aquaculture. It has been proven that mammalian HMGB (high mobility group box) can be released extracellularly and acts as an important pro-inflammatory cytokine and late mediator of inflammatory reactions. In vertebrates, HMGB’s antibody (anti-HMGB) has been shown to confer significant protection against certain local and systemic inflammatory diseases. Therefore, we investigated the functions of Ca-HMGB (oyster HMGB) and anti-CaHMGB (Ca-HMGB’s antibody) in oyster RLO/LPS (RLO or LPS)-induced disease or inflammation. Methodology/Principal Findings Sequencing analysis revealed Ca-HMGB shares conserved structures with mammalians. Tissue-specific expression indicates that Ca-HMGB has higher relative expression in hemocytes. Significant continuous up-regulation of Ca-HMGB was detected when the hemocytes were stimulated with RLO/LPS. Recombinant Ca-HMGB protein significantly up-regulated the expression levels of some cytokines. Indirect immunofluorescence study revealed that Ca-HMGB localized both in the hemocyte nucleus and cytoplasm before RLO challenge, but mainly in the cytoplasm 12 h after challenge. Western blot analysis demonstrated Ca-HMGB was released extracellularly 4–12 h after RLO challenge. Anti-CaHMGB was added to the RLO/LPS-challenged hemocyte monolayer and real-time RT-PCR showed that administration of anti-CaHMGB dramatically reduced the rate of RLO/LPS-induced up-regulation of LITAF at 4–12 h after treatment. Flow cytometry analysis indicated that administration of anti-CaHMGB reduced RLO/LPS-induced hemocyte apoptosis and necrosis rates. Conclusions/Significance Ca-HMGB can be released extracellularly and its subcellular localization varies when stimulated with RLO. Ca-HMGB is involved in oyster immune reactions and functions as a pro-inflammatory cytokine. Anti-CaHMGB can significantly suppress RLO/LPS-induced inflammatory responses and hemocyte necrosis and apoptosis, suggesting that Ca-HMGB is a potential target to prevent and control RLO/LPS-induced disease or inflammation.

My Most Memorable AAS Meeting, or How Stephen Hawking's Chauffeur and Chubby Wise's Fiddle Are Related to the Hubble Deep Field (At Least In My Mind and Experience!)  

NASA Astrophysics Data System (ADS)

Sometimes, in the most extraordinary conditions and times, strange things happen which remind us of just how small a world we really inhabit, and how so many varied things may suddenly be juxtaposed in our lives, and in the lives of others. My most memorable AAS meeting involves not only the meeting but events while getting there. It was January 1996, and we had just finished our observations and initial data reduction of the Hubble Deep Field, the members of the HDF working group doggedly coming in to the STScI by various means over the December holidays and the New Year, in the midst of several blizzards which even closed STScI for a number of days. Not surprisingly, work on the HDF AAS presentations was ongoing until the last minute, until people left snowy Baltimore for sunny San Antonio. My street was plowed for the first time in a week a few hours before my 6AM flight, so after digging out my car, with no time for sleep, between 3AM and 6AM on the morning I left, I soon discovered my own surprising connections between Stephen Hawking's chauffeur, Chubby Wise's fiddle, and the Hubble Deep Field. I'll elaborate in this paper if you're curious!

Despite the opposition of some religious and political leaders - and even the odd scientist - biological evolution made deep inroads in a culture that increasingly identified itself as secular. The introduction of pro-evolution curricula and radio broadcasts provoked occasional antievolution outbursts, but creationism remained more an object of ridicule than a threat until the last decades of the twentieth century, when first American and then Australian creationists began fomenting antievolutionism among New Zealanders. Although Stephen Jay Gould assured them in 1986 that they had little to fear from so-called scientific creationism, because it was a 'peculiarly American' phenomenon, scientific creationism by the mid-1990s had captured the allegiance of an estimated five per cent of the country and proved especially attractive to Maori and Pacific Islanders. In 1992 New Zealand creationists formed their own antievolution society, Creation Science (NZ). PMID:11624666

Use of organic petrology in sequence stratigraphic interpretations: Example from the Eocene-Oligocene boundary section, St. Stephens Quarry, Washington County, Alabama  

SciTech Connect

The type and preservation of organic matter is related to the depositional systems tract in which the sediments were deposited. Shelf sediments in the transgressive systems tract contain sparse, highly degraded phytoclasts whereas organic matter in the highstand systems tract is dominated by well-preserved phytoclasts introduced to the shelf during progradation. Because of this relationship, integration of data from organic petrology with sedimentologic and biostratigraphic results provides greater resolution in locating critical surfaces (sequence boundaries, transgressive surfaces, and surfaces of maximum starvation) that bound depositional systems tracts within the depositional sequence. The Eocene Oligocene shelf sediments exposed in St. Stephens Quarry provide an excellent example of the relationship between depositional systems tract and organic matter deposition. Deposition of the Shubuta Clay in the transgressive systems tract terminated with the surface of maximum starvation. This surface is marked by a thin (<2 cm), laterally extensive, phosphate-rich shell lag that contains only minor amounts of highly degraded phytoclasts. Graphic correlation of biostratigraphic data reveals a marine hiatus (120,000 years) within the shell lag. Deposition in the subsequent highstand systems tract resulted in an increase in well-preserved phytoclasts in the overlying Bumpnose Limestone and Red Bluff Clay. A transgressive surface forms the contact between the Red Bluff Clay and the Mint Springs Marl. Phytoclasts are less common and more degraded in the Mint Springs above the transgressive surface than in the Red Bluff below. No hiatus is observed at this surface, suggesting that the type 2 sequence boundary is conformable at this section and may exist in the Red Bluff below the transgressive surface. This integrated approach confirms and refines previous sequence stratigraphic work performed on this important Gulf Coast section.

What significance do American demographic shifts have in a global context? Hsu's essay examines what happens once individuals or identities migrate beyond the contexts that first produced them. He explores a variety of circuits: the satellite communities of Asian immigrant students who arrived on American university campuses in the late 1960s; enduring debates about a "post-city" identity, spurred by advances in cheap, efficient, world-shrinking communication technologies; and the new affinities and categories of self-identification made possible by a present-day culture that prizes interactivity and participation.

Ultrastructure and molecular characterization of the microsporidium, Nosema chrysoperlae sp. nov., from the green lacewing, Chrysoperla carnea (Stephens) (Neuroptera: Chrysopidae) used for biological pest control.  

PubMed

Lacewing larvae are generalist predators that are commercially available for aphid control on a variety of crops in both Europe and North America. Although lacewings are known for their symbiotic association with yeasts and bacteria, there are few reports of microsporidia in these natural enemies. An undescribed microsporidium was found in Chrysoperla carnea (Stephens) during the routine examination of specimens that were obtained from a commercial insectary for biological pest control. The objective of this study was to describe the pathogen by means of ultrastructure, molecular characterization and tissue pathology. All stages of the microsporidium were diplokaryotic and developed in direct contact with the host cell cytoplasm. Merogony and sporogony were not observed. Mature spores measured 3.49±0.10×1.52±0.05?m and had an isofilar polar filament with 8-10 coils that were frequently arranged in a single row, although double rows were also observed. Spores contained a lamellar polaroplast and a relatively small and inconspicuous polar vacuole was observed in the posterior region of about half of the spores that were examined. Tubular structures, similar in appearance to those in Nosema granulosis were observed in both sporonts and in spores. A cluster of small tubules was also observed in the posterior region of some spores. Microsporidian spores were observed in cells of the proventriculus, diverticulum and in epithelial cells of the posterior midgut. The Malpighian tubules, ileum, and rectum were heavily infected. Spores were also observed in the fat body, peripheral region of the ganglia, within and between the flight muscles, and beneath the cuticle. Although the tissues adjacent to the ovaries were heavily infected, microsporidian spores were not observed within the developing eggs. Pathogen transmission was not studied directly because it was difficult to maintain microsporidia-infected C. carnea in the laboratory. The presence of microsporidian spores in the alimentary canal suggests that the pathogen is transmitted per os and horizontal transmission may occur when infected larvae or adults are cannibalized by uninfected larvae. Molecular analysis of the microsporidian genome showed that the pathogen described in this study was 99% similar to Nosema bombycis, N. furnacalis, N. granulosis and N. spodopterae. Based on information gained during this study, we propose that the microsporidium in C. carnea be given the name Nosema chrysoperlae sp. nov. PMID:23727346

'Primum non nocere': A review of Taking America off Drugs: Why Behavioral Therapy is More Effective for Treating ADHD, OCD, Depression and Other Psychological Problems by Stephen Ray Flora  

PubMed Central

Taking America off Drugs by Stephen Ray Flora provides an overview of effective behavioral interventions to treat a variety of mental health concerns, including depression and phobias. These disorders are better treated with behavioral than psychopharmacological interventions. Yet, the latter prevail in today's society. Taking America off Drugs provides the background to help us understand why, as it puts the treatment of behavioral disorders in the context of modern psychiatry and its relationship with the pharmaceutical industry. This review provides an overview and critical evaluation of the book, but it also extends its context by discussing the history of the treatment of mental illness and practices of the pharmaceutical-medical complex and by offering an optimistic scenario by which psychopharmacological agents will ultimately be replaced by interventions based on the principles of applied behavior analysis.

USGS Publications Warehouse

While encamped for the winter of 1819?1820 at Engineer Cantonment along the Missouri River in present-day eastern Nebraska, members of Major Stephen Harriman Long?s Expedition to the Rocky Mountains collected a number of animals that were previously unknown. Among the mammals were two soricids that were subsequently described by Thomas Say as Sorex brevicaudus (Northern Short-tailed Shrew, Blarina brevicauda) and Sorex parvus (Least Shrew, Cryptotis parvus). The holotypes of these species were deposited and placed on public exhibit in the Philadelphia Museum, the predominant North American systematic collection of the early nineteenth century. Like most private museums of that era, the Philadelphia Museum eventually went out of business, and its collections were dispersed and, for the most part, lost. Fortunately, Titian R. Peale made a detailed field sketch of the two specimens soon after their capture and subsequently executed a watercolor based on that sketch. In addition, an engraving of the holotypes was published in the decade following the discovery of the two species. Illustrations of holotypes are taxonomically useful when they depict diagnostic characters of species. They take on added taxonomic significance in the absence of the holotypes. In the cases of Sorex brevicaudus and Sorex parvus, pictures provide strong confirmation of the taxonomic identities of these two species, as well as recording the early history of the specimens.

Goethe's phenomenology of nature: a juvenilization of science.  

PubMed

Empirical science is not a mere collection of facts. It builds theories and frames hypotheses within those theories. Empirical theories are stated as plausible answers to questions we pose to nature. According to the Galilean-Baconian tradition within science, these questions should basically explore the causes of observed phenomena, and further be restricted to the measurable and quantitative realm. Thus, the answers are generally expected to explain the effective causes behind the actual phenomena. By framing falsifiable hypotheses, the theories are tested against the empirical foundation on which they rest. In this way we try to relieve science from false theories. Thus, we have two epistemological levels: First, the theoretical level; the scientific theory explaining the phenomena, and second, the empirical level; the phenomena or facts verifying or falsifying those theories. According to the poet and multi-scientist Johann Wolfgang von Goethe (1749-1832), there is however another way of science, namely an approach where these two levels fuse and become one. Goethe intended this approach to be a complementation of the Galilean-Baconian method, more than an alternative. He considered his "hypothesis-free method" to be a more comprehensive and secure way to understand nature. Whereas the Galilean-Baconian method aimed at explaining the effective causes of natural phenomena, in order to control and exploit nature for technical and industrial purposes, Goethe aimed at an exposition of the inherent meaning of the phenomena.We will explore, exemplify and discuss this approach with reference to the inherently Goethean phenomenology of evolution credited to the Dutch anatomist Louis Bolk (1866-1930), later commented and complemented by Stephen Jay Gould (1941-2002) and Jos Verhulst (1949 ). In the course of this presentation we will outline the Goethean approach as a method representing a juvenilization or in Bolk's terms, a fetalization of science. PMID:20077388

Stephen C. Woods: a precocious scientist.  

PubMed

To investigate the early scientific development of Steve Woods, I reviewed his research during the first decade after he received his doctoral degree in 1970. The main parts of his research program were conditioned insulin secretion and hypoglycemia, Pavlovian conditioning of insulin secretion before a scheduled access to food, and basal insulin as a negative-feedback signal from fat mass to the brain. These topics were pursued with experimental ingenuity; the resulting publications were interesting, clear, and rhetorically effective. Although the theoretical framework for his experiments with insulin was homeostatic, by the end of the decade he suggested that classic negative-feedback homeostasis needed to be revised to include learning acquired by lifestyle. Thus, Woods functioned as a mature scientist from the beginning of his research-he was very precocious. This precocity also characterized his teaching and mentoring as recalled by two of his students during that time, Joseph Vasselli and Paul Kulkosky. The most unusual and exemplary aspect of his precocity is that the outstanding performance of his first decade was maintained during the subsequent 30years. PMID:21232549

L'univers clos de Stephen Hawking.  

NASA Astrophysics Data System (ADS)

Einstein had curved space, Hawking will curve time. Hawking's universe is a closed model, a 4-sphere, which encloses its own space and its own time. Nothing exists outside and without any time overlapping this 4-sphere, it cannot have a beginning, an evolution or an end. It only is. But such an absolute existence of this type of universe implies that its 3-dimensional sclices - which are our physical space - cannot have the same absolute state of being. Thus, they are necessarily transitory, with a beginning and an end, in time which is the 4th remaining dimension of the 4-sphere. Hawking absolute universe is the cause of time.

IN MY OPINION: Is Physics debatable?  

NASA Astrophysics Data System (ADS)

Stephen Jay Gould is, unfortunately, a palaeontologist. I write unfortunately because if he were a physicist we would all have benefited from his innumerable entertaining and informative essays [1]. His steady theme involves an obscure subject like palaeontology and why the subject links so strongly with the human condition. The key, of course, is evolution, and the light it sheds on what it means to be human. The new National Curriculum for England (and probably Wales) requires that pupils be taught: * how scientific controversies can arise from different ways of interpreting empirical evidence and models based on this evidence, and * ways in which scientific ideas may be affected by the context in which they develop, e.g. social, historical, moral and spiritual , and how these contexts may affect whether or not the ideas are accepted. Stephen Jay Gould produces an essay a month (in the US Natural History magazine) and so seems to have few problems in finding topics to write about that would fit well into one or both of the National Curriculum requirements. Good for biologists, but it doesn't seem to be so easy in physics. Admittedly Gould has to have recourse to a great number of historical cases - but he usually manages to link these with up-to-date issues. After all, he comes from a country where several states put `creation science' on a par with the Darwinian model of Earth history, so he has not only scope but need for encouraging some humane rationality. Can the history of physics provide such relevance? Does physics provide nice meaty controversies that might tempt the adolescent to think? We might be able to tell some stories with some level of drama, but it is hard for teachers to produce much enthusiasm in ordinary students at age 14 to 16 for controversies between Newton and Hooke, or Newton and Leibnitz (or Newton and most of his contemporaries, to be honest). They might be made to sympathize with Thomas Young, agonize over Boltzmann, celebrate with Einstein - but we are immediately into realms of physics outside the 14 - 16 curriculum, and perhaps this is just as well. Also, history is problematic. Apart from the possible aversion to dead white males, probably with beards, history is more complicated than we often think. It is easy to give wrong messages: science makes steady linear progress, modern scientists are so much smarter than these old folk who got so much of it wrong. To quote Gould [1, pp 83-4], talking about an 18th century British naturalist, a puzzled contemporary of Linnaeus: Mendes da Costa was an ordinary man in the midst of [a] great transition. ... By studying Mendes da Costa, we can best understand the fixed beliefs, the impact of novelty introduced by innovators, and, particularly, the intellectual impediments that his age posed to better comprehension of the natural world. We must learn to view these impediments with proper sympathy - not in the old style of condescension for an intellectual childhood to compare with our stunning maturity, but as a set of consistent and powerful beliefs, well suited to the culture of another time, held by reasonable people with raw intellects at least as good as ours.' I get from this that history may be best taught by historians - or at least, if by scientists, with a suitable humility. Some hard work will be required by teachers - or by anyone daring enough to provide resources suitable for tackling such problems in a way that not only makes enjoyable sense but encourages an interest and competence in physics by young people. The other main problem for physics teachers, of course, is that any attempt to deal with `different ways of interpreting empirical evidence' in contemporary physics meets a very steep and very high comprehension barrier. We are talking quantum physics, relativistic cosmology, condensed matter etc, etc. One answer might be to avoid pure physics completely and go for the jugular in technological applications. Plenty of scope here: communications, transport, energy, geophysics and climatology, just for starters. The idea will not

Effect of squeeze on electrostatic Trivelpiece-Gould wave damping  

NASA Astrophysics Data System (ADS)

We present a theory for increased damping of Trivelpiece-Gouid plasma modes on a nonneutral plasma column, due to application of a Debye shielded cylindrically symmetric squeeze potential ?1. We present two models of the effect this has on the plasma modes: a 1D model with only axial dependence, and a 2D model that also keeps radial dependence in the squeezed equilibrium and the mode. We study the models using both analytical and numerical methods. For our analytical studies, we assume that ?1/T?1, and we treat the Debye shielded squeeze potential as a perturbation in the equilibrium Hamiltonian. Our numerical simulations solve the 1D Vlasov-Poisson system and obtain the frequency and damping rate for a self-consistent plasma mode, making no assumptions as to the size of the squeeze. In both the 1D and 2D models, damping of the mode is caused by Landau resonances at energies En for which the particle bounce frequency ?b(En) and the wave frequency ? satisfy ? =n?b(En). Particles experience a non-sinusoidal wave potential along their bounce orbits due to the squeeze potential. As a result, the squeeze induces bounce harmonics with n > 1 in the perturbed distribution. The harmonics allow resonances at energies En?T that cause substantial damping, even when wave phase velocities are much larger than the thermal velocity. In the regime ? /k??T /m (k is the wave number) and T ??1, the resonance damping rate has a |?1|2 dependence. This dependence agrees with the simulations and experimental results.

What is Radical Behaviorism? A Review of Jay Moore's Conceptual Foundations of Radical Behaviorism  

PubMed Central

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.

The Luminosities of Protostars in the Spitzer c2d and Gould Belt Legacy Clouds  

NASA Astrophysics Data System (ADS)

Motivated by the long-standing "luminosity problem" in low-mass star formation whereby protostars are underluminous compared to theoretical expectations, we identify 230 protostars in 18 molecular clouds observed by two Spitzer Space Telescope Legacy surveys of nearby star-forming regions. We compile complete spectral energy distributions, calculate L bol for each source, and study the protostellar luminosity distribution. This distribution extends over three orders of magnitude, from 0.01 L ? to 69 L ?, and has a mean and median of 4.3 L ? and 1.3 L ?, respectively. The distributions are very similar for Class 0 and Class I sources except for an excess of low luminosity (L bol <~ 0.5 L ?) Class I sources compared to Class 0. 100 out of the 230 protostars (43%) lack any available data in the far-infrared and submillimeter (70 ?m

The Gould's Belt Very Large Array Survey. I. The Ophiuchus Complex  

NASA Astrophysics Data System (ADS)

We present large-scale (~2000 arcmin2), deep (~20 ?Jy), high-resolution (~1'') radio observations of the Ophiuchus star-forming complex obtained with the Karl G. Jansky Very Large Array at ? = 4 and 6 cm. In total, 189 sources were detected, 56 of them associated with known young stellar sources, and 4 with known extragalactic objects; the other 129 remain unclassified, but most of them are most probably background quasars. The vast majority of the young stars detected at radio wavelengths have spectral types K or M, although we also detect four objects of A/F/B types and two brown dwarf candidates. At least half of these young stars are non-thermal (gyrosynchrotron) sources, with active coronas characterized by high levels of variability, negative spectral indices, and (in some cases) significant circular polarization. As expected, there is a clear tendency for the fraction of non-thermal sources to increase from the younger (Class 0/I or flat spectrum) to the more evolved (Class III or weak line T Tauri) stars. The young stars detected both in X-rays and at radio wavelengths broadly follow a Güdel-Benz relation, but with a different normalization than the most radioactive types of stars. Finally, we detect a ~70 mJy compact extragalactic source near the center of the Ophiuchus core, which should be used as gain calibrator for any future radio observations of this region.

Is There Really A North American Plate?  

NASA Astrophysics Data System (ADS)

Lithospheric plates are typically identified from earthquake epicenters and evidence such as GPS movements. But no evidence indicates a plate boundary between the North American and South American Plates. Some plate maps show them separated by a transform boundary, but it is only a fracture zone. Other maps show an "undefined plate boundary" or put no boundary between these two plates (check Google images). Early plate maps showed a single large American Plate, quite narrow east of the Caribbean Plate (Le Pichon 1968, Morgan 1968). The North and South American Plates became established by the leading textbook Earth (Press & Siever 1974). On their map, from a Scientific American article by John Dewey (1972), these new plates were separated by an "uncertain plate boundary." The reasons for postulating a North American Plate were probably more psychological than geological. Each of the other continents of the world had its own plate, and North American geologists naturally wanted theirs. Similarly, European geographers used to view Europe as its own continent. A single large plate should again be hypothesized. But the term American Plate would now be ambiguous ("Which plate, North or South?") Perhaps future textbook authors could call it the "Two-American Plate." Textbook authors ultimately decide such global-tectonic matters. I became aware of textbook authors' opinions and influence from my research into the history of Alfred Wegener's continental drift (see Fixists vs. Mobilists by Krill 2011). Leading textbook author Charles Schuchert realized that continental drift would abolish his cherished paleogeographic models of large east-west continents (Eria, Gondwana) and small oceans (Poseiden, Nereis). He and his junior coauthors conspired to keep drift evidence out of their textbooks, from the 1934-editions until the 1969-editions (Physical Geology by Longwell et al. 1969, Historical Geology by Dunbar & Waage 1969). Their textbooks ruled in America. Textbooks elsewhere, such as S.J. Shand (1933), E.B. Bailey (1939), and Arthur Holmes (1944), presented continental drift as a working hypothesis that could elegantly solve important geological problems. Americans were preconditioned to dislike continental drift theory, ever since James Dwight Dana taught in his Manual of Geology (1863...1895) that North America was the type continent of the world, and that it had stood alone since earliest time. Such beliefs sometimes trump geologic evidence. As noted by Stephen Jay Gould (1999) Sigmund Freud had much insight into the psychology of scientific revolutions: they involve a scientific development that shows humans to have lesser status than previously perceived. In the Copernican revolution (geocentrism vs. heliocentrism) humans no longer inhabited the center of the universe. In the Darwinian revolution (creationism vs. evolutionism) humans were no longer uniquely created. In the Wegenerian revolution (fixism vs. mobilism) North America was no longer uniquely created; it was just other fragment from Pangaea. North American geologists were pleased when Press & Siever gave them their own lithospheric plate. Being a global-tectonic killjoy, I would like to take away that small consolation as well. Or at least pose the question: Is there really a North American Plate?

Climatic, biological, and strategic effects of nuclear war. Hearing before the Subcommittee on Natural Resources, Agriculture Research and Environment of the Committee on Science and Technology, House of Representatives, Ninety-Eighth Congress, Second Session, September 12, 1984  

SciTech Connect

A panel of experts, including Carl Sagan, Jay Gould, and Edward Teller, testified along with climate and atmospheric science experts from the Soviet Union on the long-term effects of a nuclear war. The scientists warned that such an event could repeat the biological and climatic disruption that ended the age of dinosaurs 65 million years ago. The purpose of the hearing was to inform committee members about the nature and outcome of a nuclear winter. The scientists also described international research programs designed to ascertain these long-term effects. They pointed out that, while the effects of a single explosion are well known, little is known of overlapping effects from multiple explosions. Two appendices with additional material submitted for the record and additional questions and answers follows the testimony.

Interview: Mr. Stephen Chee, team leader, UNFPA country support team (CST) for the South Pacific.  

PubMed

The UNFPA country support team (CST) for the South Pacific is the action-arm at the regional level of the new Technical Support Services arrangement introduced by the agency. Operational since April 1993, the CST currently covers the following Pacific island countries or territories: the Cook Islands, the Federated States of Micronesia, Fiji, Kiribati, Marshall Islands, Nauru, Niue, Palau, Papua New Guinea, Samoa, Solomon Islands, Tokelau, Tonga, Tuvalu, and Vanuatu. The CST office is located in Suva, Fiji, with the main goal of strengthening national capacity and building self-reliance in the countries of the region. The office in Suva is currently staffed by six highly qualified advisors with extensive experience in the population and related fields; two more advisors are expected to join the Team in early 1994. The Team is well equipped to provide countries and territories of the region with a wide range of technical support services ranging from ad hoc technical advisory services to the conceptualization and development of comprehensive population policies and programs. Services are offered in the areas of basic data collection, processing, and research in population dynamics; population policy formulation, evaluation, and implementation; family planning and maternal-child health; information, education, and communication; women in population and development; and population program management. The team also plays an advocacy role in mainstreaming population concerns into the programs and activities of international, regional, and national organizations. The team leader responds to questions about population problems experienced by the countries served, the scope of UNFPA assistance to country governments in the subregion, the importance of population information in the subregion, and how Asia-Pacific POPIN may help the team and countries served.

Response to "Radiation therapeutic gain and Asian botanicals," by Stephen Sagar.  

PubMed

Numerous botanical agents, many of which are used in whole medical system practices (i.e. traditional Chinese medicine, Ayurvedic medicine, etc.), have been shown to exhibit radiomodifying effects on tumors and normal tissues in-vitro and in-vivo studies. Some of these agents can enhance the therapeutic gain of radiation therapy by either acting as a radiosensitizer to tumor cells and/or as a radioprotector to normal cells. Botanical agents are comprised of multiple phytochemical compounds that may work individually or synergistically to not only improve radiation therapy outcomes, but may also exhibit a variety of anti-cancer effects as well. It will be important to evaluate these botanicals for efficacy, tumor specificity, and safety profiles before they can be recommended during radiation therapy. PMID:20308083

The effects of mercury on developing larvae of Rhithropanopeus harrisii (Gould) . I. Interactions of temperature, salinity and mercuryon larval development  

NASA Astrophysics Data System (ADS)

Larvae of the estuarine xanthid crab Rhithropanopeus harrisii were reared inthe laboratory from hatch through completion of metamorphosis to postlarva in 64 combinations of temperature (20-35°C), salinity (10-40‰) and mercury (0-20 parts 10 -9 Hg 2+). Multiple linear regression analysis and response surface methodology were used to determine and visually display the individual and interactive effects of the various constant temperature-salinity-mercury combinations on both survival and developmental rates of developing larvae throughout total larval development and for zoeae and megalopae separately, to distinguish any differential sensitivity between the two larval forms. Survival capacity of larvae under a broad range of salinities and temperatures characteristic of temperate estuarine conditions was progressively reduced upon continual exposure to mercury ranging from 5 to 20 parts 10 -9 Hg 2+. Exposure concentrations as low as 5 parts 10 -9 Hg 2+ reduced the salinity and temperature plasciticity of the normally euryhalinic and eurythermal larvae. Larval survival from hatch to postlarva was affected by both mercury-salinity and mercury-temperature interactions with mercury toxicity increasing under suboptimal temperatures and salinities. Viability of early zoeal stages proved more sensitive to mercury exposure than the final megalopa stage. Exposure to mercury concentrations from 5-20 parts 10 -9, Hg 2+ prolonged complete developmental duration by 3 to 4 days with zoeal developmental rates retarded more than megalopal rates. Developmental rates of the megalopa were more reduced by mercury at higher salinities, and both zoeal and megalopal developmental rates were more retarded by mercury at lower temperatures. The reduced plasticity of larvae to estuarine conditions, and retarded developmental rates by low mercury concentrations may reduce recruitment into adult benthic populations and alter the distributional patterns of pelagic R. harrisii larvae.

Differential expression of genes encoding anti-oxidant enzymes in Sydney rock oysters, Saccostrea glomerata (Gould) selected for disease resistance.  

PubMed

Sydney rock oysters (Saccostrea glomerata) selectively bred for disease resistance (R) and wild-caught control oysters (W) were exposed to a field infection of disseminating neoplasia. Cumulative mortality of W oysters (31.7%) was significantly greater than R oysters (0.0%) over the 118 days of the experiment. In an attempt to understand the biochemical and molecular pathways involved in disease resistance, differentially expressed sequence tags (ESTs) between R and W S. glomerata hemocytes were identified using the PCR technique, suppression subtractive hybridisation (SSH). Sequencing of 300 clones from two SSH libraries revealed 183 distinct sequences of which 113 shared high similarity to sequences in the public databases. Putative function could be assigned to 64 of the sequences. Expression of nine ESTs homologous to genes previously shown to be involved in bivalve immunity was further studied using quantitative reverse-transcriptase PCR (qRT-PCR). The base-line expression of an extracellular superoxide dismutase (ecSOD) and a small heat shock protein (sHsP) were significantly increased, whilst peroxiredoxin 6 (Prx6) and interferon inhibiting cytokine factor (IK) were significantly decreased in R oysters. From these results it was hypothesised that R oysters would be able to generate the anti-parasitic compound, hydrogen peroxide (H(2)O(2)) faster and to higher concentrations during respiratory burst due to the differential expression of genes for the two anti-oxidant enzymes of ecSOD and Prx6. To investigate this hypothesis, protein extracts from hemolymph were analysed for oxidative burst enzyme activity. Analysis of the cell free hemolymph proteins separated by native-polyacrylamide gel electrophoresis (PAGE) failed to detect true superoxide dismutase (SOD) activity by assaying dismutation of superoxide anion in zymograms. However, the ecSOD enzyme appears to generate hydrogen peroxide, presumably via another process, which is yet to be elucidated. This corroborates our hypothesis, whilst phylogenetic analysis of the complete coding sequence (CDS) of the S. glomerata ecSOD gene is supportive of the atypical nature of the ecSOD enzyme. Results obtained from this work further the current understanding of the molecular mechanisms involved in resistance to disease in this economically important bivalve, and shed further light on the anomalous oxidative processes involved.

NASA Astrophysics Data System (ADS)

The morphology of the megalopa stage of the panopeid Rhithropanopeus harrisii is redescribed and illustrated in detail from plankton specimens identified by DNA barcode (16S mtDNA) as previous descriptions do not meet the current standard of brachyuran larval description. Several morphological characters vary widely from those of other panopeid species which could cast some doubt on the species' placement in the same family. Besides, some anomalous megalopae of R. harrisii were found among specimens reared at the laboratory from zoeae collected in the plankton. These anomalous morphological features are discussed in terms of problems associated with laboratory rearing conditions.

THE SPITZER SURVEY OF INTERSTELLAR CLOUDS IN THE GOULD BELT. III. A MULTI-WAVELENGTH VIEW OF CORONA AUSTRALIS  

SciTech Connect

We present Spitzer Space Telescope IRAC and MIPS observations of a 0.85 deg{sup 2} field including the Corona Australis (CrA) star-forming region. At a distance of 130 pc, CrA is one of the closest regions known to be actively forming stars, particularly within its embedded association, the Coronet. Using the Spitzer data, we identify 51 young stellar objects (YSOs) in CrA which include sources in the well-studied Coronet cluster as well as sources distributed throughout the molecular cloud. Twelve of the YSOs discussed are new candidates, one of which is located in the Coronet. Known YSOs retrieved from the literature are also added to the list, and a total of 116 candidate YSOs in CrA are compiled. Based on these YSO candidates, the star formation rate is computed to be 12 M{sub sun} Myr{sup -1}, similar to that of the Lupus clouds. A clustering analysis was also performed, finding that the main cluster core, consisting of 68 members, is elongated (having an aspect ratio of 2.36), with a circular radius of 0.59 pc and mean surface density of 150 pc{sup -2}. In addition, we analyze outflows and jets in CrA by means of new CO and H{sub 2} data. We present 1.3 mm interferometric continuum observations made with the Submillimeter Array (SMA) covering R CrA, IRS 5, IRS 7, and IRAS 18595-3712 (IRAS 32). We also present multi-epoch H{sub 2} maps and detect jets and outflows, study their proper motions, and identify exciting sources. The Spitzer and ISAAC/VLT observations of IRAS 32 show a bipolar precessing jet, which drives a CO(2-1) outflow detected in the SMA observations. There is also clear evidence for a parsec-scale precessing outflow, which is east-west oriented and originates in the SMA 2 region and likely driven by SMA 2 or IRS 7A.

Jay L. King, Joseph D. Huxman, and Orion D. Billeter Assist Pilot Milt Thompson into the M2-F2 Attac  

NASA Technical Reports Server (NTRS)

NASA research pilot Milt Thompson is helped into the cockpit of the M2-F2 lifting body research aircraft at NASA's Flight Research Center (now the Dryden Flight Research Center). The M2-F2 is attached to a wing pylon under the wing of NASA's B-52 mothership. The flight was a captive flight with the pilot on-board. Milt Thompson flew in the lifting body throughout the flight, but it was never dropped from the mothership. NASA B-52, Tail Number 008, is an air launch carrier aircraft, 'mothership,' as well as a research aircraft platform that has been used on a variety of research projects. The aircraft, a 'B' model built in 1952 and first flown on June 11, 1955, is the oldest B-52 in flying status and has been used on some of the most significant research projects in aerospace history. Some of the significant projects supported by B-52 008 include the X-15, the lifting bodies, HiMAT (highly maneuverable aircraft technology), Pegasus, validation of parachute systems developed for the space shuttle program (solid-rocket-booster recovery system and the orbiter drag chute system), and the X-38. The B-52 served as the launch vehicle on 106 X-15 flights and flew a total of 159 captive-carry and launch missions in support of that program from June 1959 to October 1968. Information gained from the highly successful X-15 program contributed to the Mercury, Gemini, and Apollo human spaceflight programs as well as space shuttle development. Between 1966 and 1975, the B-52 served as the launch aircraft for 127 of the 144 wingless lifting body flights. In the 1970s and 1980s, the B-52 was the launch aircraft for several aircraft at what is now the Dryden Flight Research Center, Edwards, California, to study spin-stall, high-angle-of attack, and maneuvering characteristics. These included the 3/8-scale F-15/spin research vehicle (SRV), the HiMAT (Highly Maneuverable Aircraft Technology) research vehicle, and the DAST (drones for aerodynamic and structural testing). The aircraft supported the development of parachute recovery systems used to recover the space shuttle solid rocket booster casings. It also supported eight orbiter (space shuttle) drag chute tests in 1990. In addition, the B-52 served as the air launch platform for the first six Pegasus space boosters. During its many years of service, the B-52 has undergone several modifications. The first major modification was made by North American Aviation (now part of Boeing) in support of the X-15 program. This involved creating a launch-panel-operator station for monitoring the status of the test vehicle being carried, cutting a large notch in the right inboard wing flap to accommodate the vertical tail of the X-15 aircraft, and installing a wing pylon that enables the B-52 to carry research vehicles and test articles to be air-launched/dropped. Located on the right wing, between the inboard engine pylon and the fuselage, this wing pylon was subjected to extensive testing prior to its use. For each test vehicle the B-52 carried, minor changes were made to the launch-panel operator's station. Built originally by the Boeing Company, the NASA B-52 is powered by eight Pratt & Whitney J57-19 turbojet engines, each of which produce 12,000 pounds of thrust. The aircraft's normal launch speed has been Mach 0.8 (about 530 miles per hour) and its normal drop altitude has been 40,000 to 45,000 feet.. It is 156 feet long and has a wing span of 185 feet. The heaviest load it has carried was the No. 2 X-15 aircraft at 53,100 pounds. Project manager for the aircraft is Roy Bryant.

Large-Scale Simulation of the Effects of Climate Change on Runoff Erosion Following Extreme Wildfire Events Authors: Gould, Adam, Warren, Barber, Wagenbrenner, Robichaud, Wang, Cherkauer  

NASA Astrophysics Data System (ADS)

Across the western U.S., there is clear concern for increases in wildfire occurrence, severity, and post-fire runoff erosion due to projected climate changes. The aim of this study was to advance our capability to simulate post-fire runoff erosion at scales larger than a single hillslope to examine the relative contribution of sediment being released to larger streams and rivers in response to wildfire. We applied the Variable Capacity Infiltration-Water Erosion Prediction Project (VIC-WEPP), a newly-developed physically-based modeling framework that combines large-scale hydrology with hillslope-scale runoff erosion, over the Salmon River basin (SRB) in central Idaho. We selected the SRB for this study because of recent research that suggested that forest wildfires are likely contributing the majority of coarser sands that settle in downstream navigation channels and in reservoirs, causing adverse impacts to aquatic life, navigation, and flood storage. Using the Normalized Burn Ratio (NBR), burn intensity and severity maps show the regularity of wildfire occurrence in the SRB. These maps compare pre-fire images to next growing season images from the Landsat Thematic Mapper multispectral scanning sensor. Rather than implementing WEPP over all hillslopes within the SRB, we applied a representative hillslope approach. A monofractal scaling method downscales globally available 30 arc second digital elevation model (DEM) data to a 30 m resolution for simulations. This information determined the distribution of slope gradients within each VIC grid cell. This study applied VIC-WEPP over the 1979-2010 period and compared an ensemble of future climate simulations for the period of 2041-2070. For future scenarios, we only considered meteorological impacts on post-fire erosion and did not incorporate changes in future fire occurrence or severity. We ran scenarios for a variety of land cover and soil parameter sets, particularly those that relate to pre and post-fire characteristics, such as vegetative cover, interrill and rill erodibility factors, and saturated hydraulic conductivity. Evaluation of runoff erosion at experimental sites, observed by the U.S. Forest Service, involved using Disturbed WEPP which showed reasonable first post-fire year annual erosion predictions. We evaluated VIC-WEPP by comparing sediment observations downstream of the SRB with simulated yields for both pre and post-fire conditions. Generation of maps showing erosion over the SRB for each of the scenarios show specific areas within the SRB to be high, moderate, or low runoff-induced post-fire erosion regions. Our methodology will enable forest managers in the region to incorporate the impacts of changes in meteorological events on runoff erosion into their strategic management plans.

Theory and operation of the Gould 32/27 programs ABLE-2A and EBLE for the tropospheric air motion measurement system  

NASA Technical Reports Server (NTRS)

Software development for the Trospheric Air Motion Measurement Systems (TAMMS) is documented. In July/August the TAMMS was flown on the NASA/Goddard Flight Center Electra aircraft for 19 mission for the ABLE-2A (Amazon Boundary Layer Experiment) in Brazil. In December 1985, several flights were performed to assess the contamination and boundary layer of the Electra. Position data, flow angles, pressure transducer measurements were recorded. The programs written for the ABLE-2A were modified due to timing considerations for this particular program. The 3-step programs written for EBLE (Electra Boundary Layer Experiment) are described. Power up and log-on procedures are discussed. A few editing techniques are described for modification of the programs.

Wrongful death claims. Harriton v Stephens. [2002] NSWSC 461. Edwards v Blomeley. [2002] NSWSC 460. Waller v James [2002] NSWSC 462.  

PubMed

Studdert J in all three cases went to great length to summarise the global judicial position of "wrongful life" claims. He did not, however, examine in great length how or whether "wrongful life" claims or "wrongful birth" claims are reconcilable with tort and common law principles. Although the cases identify the difficulty in assessing and quantifying damages, they do not directly address the strict legal principles which apply in the assessment of damages. The main conclusion of the three judgments was that no duty of care is owed to the plaintiff in these circumstances and, even if a duty could be established, the impossibility of quantifying damages and public policy considerations warrant the rejection of such a claim: "thus conscience does make cowards of us all." The significance of the decisions cannot be understand. The decisions deny recognition of "wrongful life" claims in circumstances where a disabled person has incurred injuries en ventre sa mere (in the mother's womb) as a result of infections contracted by a plaintiff's mother or genetic material passed on by a plaintiff's parents. Some countries have now legislated for the abolition of "wrongful life and birth" suits. In January 2002 the French legislature passed a Bill overturning the "wrongful life" decision of the Cour de Cassation in Perruche (17 November 2000). As the issue now falls for ultimate determination by the French Senate, the French pro-life movement continues to lobby for the prohibition of "wrongful birth" suits as well. Furthermore, eight States in the United States have prohibited either one or both actions and the State of Michigan prohibited both actions in 2001. It is likely that all three cases will be appealed. The appeal in Harriton will re-examine the viability of a "wrongful life" claim in Australia whereas the cases of Edwards and Waller still need to determine the "wrongful birth" claims brought by the plaintiffs' parents. It is likely that the latter two cases will not be determined until the High Court has considered the Queensland "wrongful birth" case of Melchior v Cattanach, expected to be late in 2002.

A comment on: `TitaniQ under pressure: the effect of pressure and temperature on the solubility of Ti in quartz', by Jay B. Thomas, E. Bruce Watson, Frank S. Spear, Philip T. Shemella, Saroj K. Nayak and Antonio Lanzirotti  

NASA Astrophysics Data System (ADS)

Trace concentrations of Ti in quartz are used to indicate the pressure and temperature conditions of crystallization in the `TitaniQ' geothermobarometer of Thomas et al. (Contrib Miner Petrol 160:743-759, 2010). It utilises the partitioning of Ti into quartz as an indicator of the pressures and/or temperatures of crystal growth. For a given value of TiO2 activity in the system, if temperatures are inferred to ±20 °C, pressure is constrained to ±1 kbar and vice versa. There are significant contrasts, however, between the conclusions from TitaniQ and those for natural quartz (as well as other mineral phases) in volcanic rocks. Application of the TitaniQ model to quartz from the 27 ka Oruanui and 760 ka Bishop high-silica rhyolites, where the values of T, P and TiO2 activity are constrained by other means (Fe-Ti oxide equilibria, melt inclusion entrapment pressures in gas-saturated melts, melt and amphibole compositions), yields inconsistent results. If realistic values are given to any two of these three parameters, then the value of the third is wholly unrealistic. The model yields growth temperatures at or below the granite solidus, pressures in the lower crust or upper mantle, or TiO2 activities inconsistent with the mineralogical and chemical compositions of the magmas. CL imagery and measurements of Ti (and other elements) in quartz are of great value in showing the growth histories and changes in conditions experienced by crystals, but direct linkages to P, T conditions during crystal growth cannot be achieved.

Monozygotic twins concordant for autism and hyperlexia.  

PubMed

The authors describe male monozygotic twins, Jon and Jay, who are concordant for autism and hyperlexia. Autism and mental retardation were diagnosed at the age of 2 years 5 months. Jay was the more advanced twin in motor co-ordination, attention span and receptive abilities, but had frequent tantrums. When psychologically assessed at 7 years 2 months, Jon showed borderline/severe mental retardation on the measure of non-verbal intelligence and Jay was moderately retarded. Their receptive language age was greater than their expressive language age: Jon's speech was less mature but more communicative and Jay's was perseverative and ritualistic. Even though Jon was the more mentally retarded twin, Jay was the more autistic in some behavioral aspects. These twins highlight the relationship between autism and hyperlexia. PMID:3169393

UPTAKE OF ORGANIC MATERIAL BY AQUATIC INVERTEBRATES. IV. THE INFLUENCE OF SALINITY ON THE UPTAKE OF AMINO ACIDS BY THE BRITTLE STAR, OPHIACTIS ARENOSA  

Microsoft Academic Search

The ability to remove amino acids and other small organic compounds from dilute solution is widespread among marine invertebrates. Stephens and Schinske (1961 ) reported examples from ten different phyla. This capacity has been studied in additional forms and has provided material for a series of reports ( Stephens, 1962, 1963, 1964 ; Stephens et a!., 1965 ; Virkar, 1963)

Endangered and Threatened Species at Kennedy Space Center Merritt Island National Wildlife Refuge  

NASA Technical Reports Server (NTRS)

Throughout my internship, I assisted with the long-term monitoring of the Florida Scrub- Jay (Aphelocoma coerulescens), a threatened species endemic to Florida. The Florida Scrub Jay diet consists of insects and small vertebrates throughout most of the year; however, during the winter their primary diet is acorns because the insect population is low. Furthermore, the Florida Scrub-Jay is a habitat specialist that lives in a disappearing plant community called the scrub, which consists of sand live oak, myrtle oak and chapman oak. The Florida Scrub-Jay is considered threatened because its numbers are decreasing primarily due to the loss of habitat that it needs to survive. Scrub habitat is highly desirable for human development because it is high, dry, and sandy. Periodic controlled burns maintain the scrub in a low, open condition favored by Scrub-Jays. Florida Scrub-Jays build their nests approximately 3-5 feet (approximately 1.5 m) above the ground in shrubby oaks (Breininger 153), mate for life and are cooperative breeders; which means that the young jays remain in their natal territory for at least a year to help their parents defend their territory, feed the young, and mob predators. (Breininger 152). I assisted in conducting monthly censuses at long-term monitoring sites and a juvenile in July survey to determine reproductive success for the year. In addition, to Scrub-Jay monitoring, I also had the opportunity to assist with some long term monitoring of ecosystem recovery. Scrub is a fire maintained system. Fire maintains the structure of scrub necessary for many of the threatened species that reside in the scrub habitat.

Mobbing calls signal predator category in a kin group-living bird species.  

PubMed

Many prey species gather together to approach and harass their predators despite the associated risks. While mobbing, prey usually utter calls and previous experiments have demonstrated that mobbing calls can convey information about risk to conspecifics. However, the risk posed by predators also differs between predator categories. The ability to communicate predator category would be adaptive because it would allow other mobbers to adjust their risk taking. I tested this idea in Siberian jays Perisoreus infaustus, a group-living bird species, by exposing jay groups to mounts of three hawk and three owl species of varying risks. Groups immediately approached to mob the mount and uttered up to 14 different call types. Jays gave more calls when mobbing a more dangerous predator and when in the presence of kin. Five call types were predator-category-specific and jays uttered two hawk-specific and three owl-specific call types. Thus, this is one of the first studies to demonstrate that mobbing calls can simultaneously encode information about both predator category and the risk posed by a predator. Since antipredator calls of Siberian jays are known to specifically aim at reducing the risk to relatives, kin-based sociality could be an important factor in facilitating the evolution of predator-category-specific mobbing calls.

Detection of Persistent West Nile Virus RNA in Experimentally and Naturally Infected Avian Hosts  

PubMed Central

To determine whether West Nile virus (WNV) persistent infection in avian hosts may potentially serve as an overwintering mechanism, House Sparrows and House Finches, experimentally and naturally infected with several strains of WNV, and two naturally infected Western Scrub-Jays were held in mosquito-proof outdoor aviaries from 2007–March 2008. Overall, 94% (n = 36) of House Sparrows, 100% (n = 14) of House Finches and 2 Western Scrub-Jays remained WNV antibody positive. When combined by species, 37% of the House Sparrows, 50% of the House Finches, and 2 Western Scrub-Jays were WNV RNA positive at necropsy, up to 36 weeks post-infection. Infectious WNV was not detected. Our study supports the hypothesis that some avian hosts support the long-term persistence of WNV RNA, but it remains unresolved whether these infections relapse to restart an avian-arthropod transmission cycle and thereby serve as an overwintering mechanism for WNV.

Accessibility is a concept that is not entirely easy to define. Gould (1969) once stated that it is a ‘slippery notion … one of those common terms that everyone uses until faced with the problem of defining and measuring it’. Considerable research over the last 40 years has been devoted to defining and measuring accessibility, ranging from access to jobs

Bohm-condition for nonneutral plasma streams  

NASA Astrophysics Data System (ADS)

It is demonstrated through a time-dependent particle simulation that an extended sheath forms spontaneously when a nonneutral plasma reflects from a potential barrier. An analytical description shows that extended sheaths develop when the flow velocity is smaller than the Gould-Trivelpiece speed, hence a generalization of the Bohm-condition to nonneutral systems is obtained.

Oscillation spectrum of an electron gas with a small density fraction of ions  

SciTech Connect

The problem is solved of the stability of a nonneutral plasma that completely fills a waveguide and consists of magnetized cold electrons and a small density fraction of ions produced by ionization of the atoms of the background gas. The ions are described by an anisotropic distribution function that takes into account the characteristic features of their production in crossed electric and magnetic fields. By solving a set of Vlasov-Poisson equations analytically, a dispersion equation is obtained that is valid over the entire range of allowable electric and magnetic field strengths. The solutions to the dispersion equation for the m = +1 main azimuthal mode are found numerically. The plasma oscillation spectrum consists of the families of Trivelpiece-Gould modes at frequencies equal to the frequencies of oblique Langmuir oscillations Doppler shifted by the electron rotation and also of the families of 'modified' ion cyclotron (MIC) modes at frequencies close to the harmonics of the MIC frequency (the frequencies of radial ion oscillations in crossed fields). It is shown that, over a wide range of electric and magnetic field strengths, Trivelpiece-Gould modes have low frequencies and interact with MIC modes. Trivelpiece-Gould modes at frequencies close to the harmonics of the MIC frequency with nonnegative numbers are unstable. The lowest radial Trivelpiece-Gould mode at a frequency close to the zeroth harmonic of the MIC frequency has the fastest growth rate. MIC modes are unstable over a wide range of electric and magnetic field strengths and grow at far slower rates. For a low ion density, a simplified dispersion equation is derived perturbatively that accounts for the nonlocal ion contribution, but, at the same time, has the form of a local dispersion equation for a plasma with a transverse current and anisotropic ions. The solutions to the simplified dispersion equation are obtained analytically. The growth rates of the Trivelpiece-Gould modes and the behavior of the MIC modes agree with those obtained by numerical simulation.

FERMI OBSERVATIONS OF CASSIOPEIA AND CEPHEUS: DIFFUSE GAMMA-RAY EMISSION IN THE OUTER GALAXY  

SciTech Connect

We present the analysis of the interstellar gamma-ray emission measured by the Fermi Large Area Telescope toward a region in the second Galactic quadrant at 100{sup 0} <= l <= 145{sup 0} and -15{sup 0} <= b <= +30{sup 0}. This region encompasses the prominent Gould Belt clouds of Cassiopeia, Cepheus, and the Polaris flare, as well as atomic and molecular complexes at larger distances, like that associated with NGC 7538 in the Perseus arm. The good kinematic separation in velocity between the local, Perseus, and outer arms, and the presence of massive complexes in each of them, make this region well suited to probe cosmic rays (CRs) and the interstellar medium beyond the solar circle. The gamma-ray emissivity spectrum of the gas in the Gould Belt is consistent with expectations based on the locally measured CR spectra. The gamma-ray emissivity decreases from the Gould Belt to the Perseus arm, but the measured gradient is flatter than expectations for CR sources peaking in the inner Galaxy as suggested by pulsars. The X{sub CO} = N(H{sub 2})/W{sub CO} conversion factor is found to increase from (0.87 +- 0.05) x 10{sup 20} cm{sup -2} (K km s{sup -1}){sup -1} in the Gould Belt to (1.9 +- 0.2) x 10{sup 20} cm{sup -2} (K km s{sup -1}){sup -1} in the Perseus arm. We derive masses for the molecular clouds under study. Dark gas, not properly traced by radio and microwave surveys, is detected in the Gould Belt through a correlated excess of dust and gamma-ray emission: its mass amounts to {approx}50% of the CO-traced mass.
