  11. Nutrition in medical education: reflections from an initiative at the University of Cambridge

    PubMed Central

    Ball, Lauren; Crowley, Jennifer; Laur, Celia; Rajput-Ray, Minha; Gillam, Stephen; Ray, Sumantra

    2014-01-01

    Landmark reports have confirmed that it is within the core responsibilities of doctors to address nutrition in patient care. There are ongoing concerns that doctors receive insufficient nutrition education during medical training. This paper provides an overview of a medical nutrition education initiative at the University of Cambridge, School of Clinical Medicine, including 1) the approach to medical nutrition education, 2) evaluation of the medical nutrition education initiative, and 3) areas identified for future improvement. The initiative utilizes a vertical, spiral approach during the clinically focused years of the Cambridge undergraduate and graduate medical degrees. It is facilitated by the Nutrition Education Review Group, a group associated with the UK Need for Nutrition Education/Innovation Programme, and informed by the experiences of their previous nutrition education interventions. Three factors were identified as contributing to the success of the nutrition education initiative including the leadership and advocacy skills of the nutrition academic team, the variety of teaching modes, and the multidisciplinary approach to teaching. Opportunities for continuing improvement to the medical nutrition education initiative included a review of evaluation tools, inclusion of nutrition in assessment items, and further alignment of the Cambridge curriculum with the recommended UK medical nutrition education curriculum. This paper is intended to inform other institutions in ongoing efforts in medical nutrition education. PMID:24899813

  14. Alchemy in Cambridge. An Annotated Catalogue of Alchemical Texts and Illustrations in Cambridge Repositories.

    PubMed

    Timmermann, Anke

    2015-01-01

    Alchemy in Cambridge captures the alchemical content of 56 manuscripts in Cambridge, in particular the libraries of Trinity College, Corpus Christi College and St John's College, the University Library and the Fitzwilliam Museum. As such, this catalogue makes visible a large number of previously unknown or obscured alchemica. While extant bibliographies, including those by M.R. James a century ago, were compiled by polymathic bibliographers for a wide audience of researchers, Alchemy in Cambridge benefits from the substantial developments in the history of alchemy, bibliography, and related scholarship in recent decades. Many texts are here identified for the first time. Another vital feature is the incorporation of information on alchemical illustrations in the manuscripts, intended to facilitate research on the visual culture of alchemy. The catalogue is aimed at historians of alchemy and science, and of high interest to manuscript scholars, historians of art and historians of college and university libraries. PMID:26245008

Ksc employees put in about 3,300 volunteer hours to transform old, excess computers into upgraded, usable units. A total of $90,000 in upgraded computer equipment is being donated.

  19. Artificial Pancreas Project at Cambridge 2013.

    PubMed

    Hovorka, R

    2015-08-01

    The development and clinical testing of closed-loop systems (the artificial pancreas) is underpinned by advances in continuous glucose monitoring and benefits from concerted academic and industry collaborative efforts. This review describes the progress of the Artificial Pancreas Project at the University of Cambridge from 2006 to 2014. Initial studies under controlled laboratory conditions, designed to collect representative safety and performance data, were followed by short to medium free-living unsupervised outpatient studies demonstrating the safety and efficacy of closed-loop insulin delivery using a model predictive control algorithm. Accompanying investigations included assessment of the psychosocial impact and key factors affecting glucose control such as insulin kinetics and glucose absorption. Translation to other disease conditions such as critical illness and Type 2 diabetes took place. It is concluded that innovation of iteratively enhanced closed-loop systems will provide tangible means to improve outcomes and quality of life in people with Type 1 diabetes and their families in the next decade.

  20. The Cambridge Illustrated History of Astronomy

    NASA Astrophysics Data System (ADS)

    Hoskin, Michael

    Expertly written and lavishly illustrated, The Cambridge Illustrated History of Astronomy offers a unique account of astronomical theory and practice from antiquity to the present day. How did Moslems of the Middle Ages use astronomy to calculate the direction of Mecca from far-flung corners of the Islamic world? Who was the only ancient Greek to suspect that the earth might revolve around the sun? How did Christopher Columbus abuse his knowledge of a lunar eclipse predicted by an astronomical almanac? Packed with anecdotes and intriguing detail, this book describes how we observed the sky and interpreted what we saw at different periods of history; how this influenced our beliefs and mythology; and how great astronomers contributed to what we now know. The result is a lively and highly visual history of astronomy - a compelling read for specialists and non-specialists alike.

  3. An investigation into the impact of question structure on the performance of first year physics undergraduate students at the University of Cambridge

    NASA Astrophysics Data System (ADS)

    Gibson, Valerie; Jardine-Wright, Lisa; Bateman, Elizabeth

    2015-07-01

    We describe a study of the impact of exam question structure on the performance of first year Natural Sciences physics undergraduates from the University of Cambridge. The results show conclusively that a student’s performance improves when questions are scaffolded compared with university style questions. In a group of 77 female students we observe that the average exam mark increases by 13.4% for scaffolded questions, which corresponds to a 4.9 standard deviation effect. The equivalent observation for 236 male students is 9% (5.5 standard deviations). We also observe a correlation between exam performance and A2-level marks for UK students, and that students who receive their school education overseas, in a mixed gender environment, or at an independent school are more likely to receive a first class mark in the exam. These results suggest a mis-match between the problem-solving skills and assessment procedures between school and first year university and will provide key input into the future teaching and assessment of first year undergraduate physics students.

  17. A histological study of retrieved Cambridge acetabular components.

    PubMed

    Brooks, Roger A; Field, Richard E; Jones, Eric; Sood, Asheesh; Rushton, Neil

    2010-01-01

    A new uncemented acetabular component, the Cambridge cup, has been designed to mimic the anatomy and physiology of subchondral bone in order to minimise stress shielding and enhance long-term component stability. Cambridge cups were implanted in a cohort of 50 women who presented with displaced sub-capital fracture of the femoral neck. The cups were manufactured with an hydroxyapatite (HA) coating. Twenty six cups were implanted after removal of the HA. Twelve Cambridge cups were retrieved post-mortem between two and 84 months after implantation. Histological and histomorphometric testing was undertaken to analyse the residual HA coating thickness, bone apposition to the implant surface and particulate wear debris in the surrounding tissues. The HA-coated implants showed significantly greater bone apposition to the implant surface with significantly less fibrous tissue formation than the uncoated implants. Where HA resorption occurred, bone and bone marrow was seen adjacent to the implant. Excessive wear of the ultra high molecular weight polyethylene liner was not seen. The HA-coated components demonstrated good initial bone implant bonding and the flexible carbon polymer appeared to maintain stability following HA resorption. The uncoated implants showed little or no bony apposition but had a fibrous membrane apposed to the implant surface. This may be explained by a combination of micro-motion at the bone implant interface and having a component surface finish that was poorly suited to osseous attachment. Hydroxyapatite coated acetabular components can provide reliable osseous attachment. Subsequent HA resorption need not compromise medium-term osseous fixation to an appropriate implant surface.

  20. Applications of the Cambridge Structural Database in chemical education1

    PubMed Central

    Battle, Gary M.; Ferrence, Gregory M.; Allen, Frank H.

    2010-01-01

    The Cambridge Structural Database (CSD) is a vast and ever growing compendium of accurate three-dimensional structures that has massive chemical diversity across organic and metal–organic compounds. For these reasons, the CSD is finding significant uses in chemical education, and these applications are reviewed. As part of the teaching initiative of the Cambridge Crystallographic Data Centre (CCDC), a teaching subset of more than 500 CSD structures has been created that illustrate key chemical concepts, and a number of teaching modules have been devised that make use of this subset in a teaching environment. All of this material is freely available from the CCDC website, and the subset can be freely viewed and interrogated using WebCSD, an internet application for searching and displaying CSD information content. In some cases, however, the complete CSD System is required for specific educational applications, and some examples of these more extensive teaching modules are also discussed. The educational value of visualizing real three-dimensional structures, and of handling real experimental results, is stressed throughout. PMID:20877495

  7. The Cambridge-Cambridge x-ray serendipity survey. 2: Classification of x-ray luminous galaxies

    NASA Technical Reports Server (NTRS)

    Boyle, B. J.; Mcmahon, R. G.; Wilkes, B. J.; Elvis, Martin

    1994-01-01

    We present the results of an intermediate-resolution (1.5 A) spectroscopic study of 17 x-ray luminous narrow emission-line galaxies previously identified in the Cambridge-Cambridge ROSAT Serendipity Survey and the Einstein Extended Medium Sensitivity Survey. Emission-line ratios reveal that the sample is composed of ten Seyfert and seven starburst galaxies. Measured linewidths for the narrow H alpha emission lines lie in the range 170 - 460 km s(exp -1). Five of the objects show clear evidence for asymmetry in the (OIII) lambda 5007 emission-line profile. Broad H alpha emission is detected in six of the Seyfert galaxies, which range in type from Seyfert 1.5 to 2. Broad H beta emission is only detected in one Seyfert galaxy. The mean full width at half maximum for the broad lines in the Seyfert galaxies is FWHM = 3900 +/- 1750 km s(exp -1). Broad (FWHM = 2200 +/- 600 km s(exp -1) H alpha emission is also detected in three of the starburst galaxies, which could originate from stellar winds or supernovae remnants. The mean Balmer decrement for the sample is H alpha / H beta = 3, consistent with little or no reddening for the bulk of the sample. There is no evidence for any trend with x-ray luminosity in the ratio of starburst galaxies to Seyfert galaxies. Based on our previous observations, it is therefore likely that both classes of object comprise approximately 10 percent of the 2 keV x-ray background.

    Viewing the reception of psychoanalysis in Britain from Cambridge, the paper examines the intertwining histories of the post-War British Psychological Society and the founding of the British Psycho-Analytical Society, following the initiatives of the two principal psychological entrepreneurs of the era, Charles Myers and Ernest Jones, Reforms in Cambridge in which psychoanalysis played a significant part are analysed, including the foundation of a Clinic for Nervous Diseases and the establishment of a separate Department of Experimental Psychology. The career of J. T. MacCurdy, Jones's student and Lecturer in Psychopathology at Cambridge, is discussed. PMID:19618518

  9. Development and Current Status of the “Cambridge” Loudness Models

    PubMed Central

    2014-01-01

    This article reviews the evolution of a series of models of loudness developed in Cambridge, UK. The first model, applicable to stationary sounds, was based on modifications of the model developed by Zwicker, including the introduction of a filter to allow for the effects of transfer of sound through the outer and middle ear prior to the calculation of an excitation pattern, and changes in the way that the excitation pattern was calculated. Later, modifications were introduced to the assumed middle-ear transfer function and to the way that specific loudness was calculated from excitation level. These modifications led to a finite calculated loudness at absolute threshold, which made it possible to predict accurately the absolute thresholds of broadband and narrowband sounds, based on the assumption that the absolute threshold corresponds to a fixed small loudness. The model was also modified to give predictions of partial loudness—the loudness of one sound in the presence of another. This allowed predictions of masked thresholds based on the assumption that the masked threshold corresponds to a fixed small partial loudness. Versions of the model for time-varying sounds were developed, which allowed prediction of the masked threshold of any sound in a background of any other sound. More recent extensions incorporate binaural processing to account for the summation of loudness across ears. In parallel, versions of the model for predicting loudness for hearing-impaired ears have been developed and have been applied to the development of methods for fitting multichannel compression hearing aids.

    Elaver O. Pickard-Cambridge, 1898 is characterized and redescribed, including 49 species occurring from the United States to Argentina. Thirty seven previously known species are redescribed: Elaver achuca (Roddy, 1966) revalidated, E. balboae (Chickering, 1937), E. barroana (Chickering, 1937), E. calcarata (Kraus, 1955), E. carlota (Bryant, 1940), E. chisosa (Roddy, 1966), E. crinophora (Franganillo, 1934), E. crocota (O. Pickard-Cambridge, 1896), E. albicans (Franganillo, 1930) name restored, E. depuncta O. Pickard-Cambridge, 1898, E. elaver (Bryant, 1940), E. excepta (L. Koch, 1866), E. grandivulva (Mello-Leitão, 1930), E. hortoni (Chickering, 1937), E. implicata (Gertsch, 1941), E. juana (Bryant, 1940), E. kohlsi (Gertsch & Jellison, 1939), E. linguata (F.O. Pickard-Cambridge, 1900), E. madera (Roddy, 1966), E. mirabilis (O. Pickard-Cambridge, 1896) new. comb., E. mulaiki (Gertsch, 1935), E. multinotata (Chickering, 1937), E. orvillei (Chickering, 1937), E. placida O. Pickard-Cambridge, 1898, E. portoricensis (Petrunkevitch, 1930), E. quadrata (Kraus, 1955), E. richardi (Gertsch, 1941), E. sericea O. Pickard-Cambridge, 1898, E. sigillata (Petrunkevitch, 1925), E. simplex (O. Pickard-Cambridge, 1896), E. texana (Gertsch, 1933), E. tigrina O. Pickard-Cambridge, 1898 name restored, E. tricuspis (F.O. Pickard-Cambridge, 1900), E. tristani (Banks, 1909), E. tumivulva (Banks, 1909),  E. valvula (F.O. Pickard-Cambridge, 1900) and E. wheeleri (Roewer, 1933). Ten new species are described: E. candelaria n. sp. and E. helenae n. sp. from Mexico; E. arawakan n. sp. from Haiti; E. lizae n. sp. from Costa Rica; E. darwichi n. sp. from Ecuador; E. juruti n. sp., E. tourinhoae n. sp. and E. vieirae n. sp. from Brazil; E. shinguito n. sp. from Peru and E. beni n. sp. from Bolivia. The female of E. hortoni is described for the first time. Lectotypes are designated for E. sigillata and its actual female is described for the first time. Four new synonyms are proposed: E. languida (Gertsch, 1941) is synonimized with E. multinotata; E. dorothea (Gertsch, 1935) with E. wheeleri; E. exempta (Gertsch & Davis, 1940) with E. placida and E. vulnerata (Kraus, 1955) with E. calcarata. The drawings in the original descriptions of E. kawitpaaia (Barrion & Litsinger, 1995) and E. turongdaliriana (Barrion & Litsinger, 1995) are sufficiently informative to exclude these species from Elaver but not to accurately establish its generic affiliation. Thus, until the types become available for examination, these species must remain as Clubionidae incertae sedis. Heterochemmis (F.O. Pickard-Cambridge, 1900) is synonymized with Elaver and Heterochemmis mutatus Gertsch & Davis,1940 is recognized as a junior synonym of Elaver mirabilis n. comb., the type species of Heterochemmis. New records are presented for E. valvula, E. balboae, E. brevipes (Keyserling, 1891), E. grandivulva and E. lutescens (Schmidt, 1971). Two species described by Franganillo, E. tenera (Franganillo, 1935) and E. tenuis (Franganillo, 1935), are considered species inquirendae. PMID:26624731

    R. C. Punnett, the codiscoverer of linkage with W. Bateson in 1904, had the good fortune to be invited to be the first Arthur Balfour Professor of Genetics at Cambridge University, United Kingdom, in 1912 when Bateson, for whom it had been intended, declined to leave his new appointment as first Director of the John Innes Horticultural Institute. We here celebrate the centenary of the first professorship dedicated to genetics, outlining Punnett's career and his scientific contributions, with special reference to the discovery of "partial coupling" in the sweet pea (later "linkage") and to the diagram known as Punnett's square. His seeming reluctance as coauthor with Bateson to promote the reduplication hypothesis to explain the statistical evidence for linkage is stressed, as is his relationship with his successor as Arthur Balfour Professor, R. A. Fisher. The background to the establishment of the Professorship is also described. PMID:22964834

    The Centre for Molecular Informatics, formerly Unilever Centre for Molecular Science Informatics (UCMSI), at the University of Cambridge is a world-leading driving force in the field of cheminformatics. Since its opening in 2000 more than 300 scientific articles have fundamentally changed the field of molecular informatics. The Centre has been a key player in promoting open chemical data and semantic access. Though mainly focussing on basic research, close collaborations with industrial partners ensured real world feedback and access to high quality molecular data. A variety of tools and standard protocols have been developed and are ubiquitous in the daily practice of cheminformatics. Here, we present a retrospective of cheminformatics research performed at the UCMSI, thereby highlighting historical and recent trends in the field as well as indicating future directions.

    Many research questions require a within-class object recognition task matched for general cognitive requirements with a face recognition task. If the object task also has high internal reliability, it can improve accuracy and power in group analyses (e.g., mean inversion effects for faces vs. objects), individual-difference studies (e.g., correlations between certain perceptual abilities and face/object recognition), and case studies in neuropsychology (e.g., whether a prosopagnosic shows a face-specific or object-general deficit). Here, we present such a task. Our Cambridge Car Memory Test (CCMT) was matched in format to the established Cambridge Face Memory Test, requiring recognition of exemplars across view and lighting change. We tested 153 young adults (93 female). Results showed high reliability (Cronbach's alpha = .84) and a range of scores suitable both for normal-range individual-difference studies and, potentially, for diagnosis of impairment. The mean for males was much higher than the mean for females. We demonstrate independence between face memory and car memory (dissociation based on sex, plus a modest correlation between the two), including where participants have high relative expertise with cars. We also show that expertise with real car makes and models of the era used in the test significantly predicts CCMT performance. Surprisingly, however, regression analyses imply that there is an effect of sex per se on the CCMT that is not attributable to a stereotypical male advantage in car expertise. PMID:22012343

    The City of Cambridge compiled data related to the market for a continued or expanded DHC system. This would build upon existing systems in the City, principally that of the Cambridge Steam Corporation. The study examined various cost alternatives to determine the competitive level which would assure market penetration. It includes an examination of technical issues relating to the existing DHC systems and an investigation of developer receptiveness to DHC. The study also includes an analysis of relevant utility regulations and a synthesis of the component costs of a DHC system. Cambridge's study concluded that cost allocation changes to reflect the true cost of steam would be necessary to assure viability of a DHC system based on the existing system. It recommended efforts with the Department of Public Utilities of Massachusetts to develop a more equitable cost allocation methodology. It also concluded that waste to energy conversion had potential as a heat source for a DHC system. It recommended a more detailed feasibility study to consider these issues in greater detail.

    The ARIES Collaborative, a U.S. Department of Energy Building America research team, partnered with NeighborWorks America affiliate Homeowners' Rehab Inc. (HRI) of Cambridge, Massachusetts, to study improvements to the central hydronic heating system in one of the nonprofit's housing developments. The heating controls in the three-building, 42-unit Columbia Cambridge Alliance for Spanish Tenants housing development were upgraded. Fuel use in the development was excessive compared to similar properties. A poorly insulated thermal envelope contributed to high energy bills, but adding wall insulation was not cost-effective or practical. The more cost-effective option was improving heating system efficiency. Efficient operation of the heating system faced several obstacles, including inflexible boiler controls and failed thermostatic radiator valves. Boiler controls were replaced with systems that offer temperature setbacks and one that controls heat based on apartment temperature in addition to outdoor temperature. Utility bill analysis shows that post-retrofit weather-normalized heating energy use was reduced by 10%-31% (average of 19%). Indoor temperature cutoff reduced boiler runtime (and therefore heating fuel consumption) by 28% in the one building in which it was implemented. Nearly all savings were obtained during night which had a lower indoor temperature cut off (68 degrees F) than day (73 degrees F). This implies that the outdoor reset curve was appropriately adjusted for this building for daytime operation. Nighttime setback of heating system supply water temperature had no discernable impact on boiler runtime or gas bills.

    2014-01-01

    Frederick Octavius Pickard-Cambridge (1905) described the monotypic genus Hernandarioides based on the species Hernandarioides plana F.O. Pickard-Cambridge, 1905, from Bugaba, Panama. The etymology of the generic name was inspired by the pre-existing Hernandaria Sørensen, 1884, because of the obliteration of the scutal grooves (which in this case is a convergence between the two unrelated groups Ampycinae and Hernandariinae). The species description was based only on the female holotype. Modern taxonomic descriptions of laniatorean harvestmen are most commonly based upon male holotypes because females lack many diagnostic characters. The holotype, deposited in the Natural History Museum, London, is brittle and does not bring much meaningful information about the species. Hernandarioides was not originally included in any subfamily of Gonyleptidae, and was included by Roewer (1913: 464) in the Hernandariinae. Goodnight & Goodnight (1942: 18) described in Prostygninae the monotypic genus Kaluga along with the species Kaluga elongata Goodnight & Goodnight, 1942, from Casita Alta, a locality very close to Bugaba, providing uninformative illustrative material. A little later, Goodnight & Goodnight (1947: 15) synonymized Kaluga with Hernandarioides and Kaluga elongata with Hernandarioides plana. Kury (2003: 105) proposed the unjustified emendation Hernandarioides planus. Finally Kury & Alonso-Zarazaga (2011: 53) transferred the genus to the Ampycinae and explained that the grammatical gender of Hernandarioides is feminine, reestablishing the original inflection Hernandarioides plana.  PMID:25081774

    Encouraging people out of their cars and into other modes of transport, which has major advantages for health, the environment and urban development, has proved difficult. Greater understanding of the influences that lead people to use the car, particularly for shorter journeys, may help to achieve this. This paper examines the predictors of car use compared with the bicycle to explore how it may be possible to persuade more people to use the bicycle instead of the car. Multivariable logistic regression was used to examine the socio-demographic, transport and health-related correlates of mode choice for work, shopping and leisure trips in Cambridge, a city with high levels of cycling by UK standards. The key findings are that commuting distance and free workplace parking were strongly associated with use of the car for work trips, and car availability and lower levels of education were associated with car use for leisure, shopping and short-distanced commuting trips. The case of Cambridge shows that more policies could be adopted, particularly a reduction in free car parking, to increase cycling and reduce the use of the car, especially over short distances.

    Ustundag, D.; Queen, N. M.; Skinner, G. K.; Bowcock, J. E.

    The authors consider two new methods for retrieving an image from noisy, incomplete data, based on the principle of maximum entropy. The image is reconstructed by either placing grains one at a time into image pixels, or transferring them between randomly chosen pairs of pixels on the basis of certain deterministic rules. The performance of the methods is tested for an application in X-ray astronomy and compared with that of the Cambridge MaxEnt package. They also demonstrate the application of the Cambridge MaxEnt package to a real problem in X-ray astronomy.

    Background: Factor V G1691A (FV Leiden), FII GA20210, and methylenetetrahydrofolate reductase (MTHFR) C677T mutations are the most common genetic risk factors for thromboembolism in the Western countries. However, there is rare data in Iran about cerebral venous and sinus thrombosis (CVST) patients. The aim of this study was to evaluate the frequency of common genetic thrombophilic factors in CVST patients. Materials and Methods: Forty consequently CVST patients from two University Hospital in Isfahan University of Medical Sciences aged more than 15 years from January 2009 to January 2011 were recruited. In parallel, 51 healthy subjects with the same age and race from similar population selected as controls. FV Leiden, FII GA20210, MTHFR C677T, and FV Cambridge gene mutations by polymerase chain reaction technique were evaluated in case and control groups. Results: FV Leiden, FII GA20210, and FV Cambridge gene mutations had very low prevalence in both case (5%, 2%, 0%) and control (2.5%, 0%, 0%) and were not found any significant difference between groups. MTHFR C677T mutations was in 22 (55%) of patients in case group and 18 (35.5%) of control group (P = 0.09). Conclusion: This study showed that the prevalence of FV Leiden, FII GA20210, and FV Cambridge were low. Laboratory investigations of these mutations as a routine test for all patients with CVST may not be cost benefit. PMID:26600830

    The occurrence of a number of pharmaceutically acceptable counterions in the Cambridge Structural Database (CSD) has been investigated. The results have been compared to the occurrence of the same counterions in a list of known pharmaceutical salts. Chloride salts are by far the highest occurring in both groups. The occurrence of hydrates in the structures of salts of pharmaceutically acceptable counterions in the CSD has also been investigated. It was found that salts of these counterions show an increased tendency to hydrate when compared to the database average. The CSD was also searched for co-crystals of the list of pharmaceutically acceptable acids and bases corresponding to the list of counterions used for the salt investigation. PMID:16136575

    In a 12-month study 132 patients injured in agricultural accidents were treated at the Accident Service of Addenbrooke's Hospital, Cambridge. Agricultural machinery and implements were concerned in 50% of the accidents and animals in 10%. The state of immunity against tetanus of these patients was found to be extremely low, only 9% being fully immunized, and 56% having never received a course of prophylactic adsorbed tetanus toxoid. While prevention is obviously the only real solution to accidents of any nature, legislation is not enough to achieve this, and the final responsibility lies with the farmworker to ensure that all safety precautions are followed.

    The Cambridge Neuropsychological Test Automated Battery (CANTAB) is a semiautomated computer interface for assessing cognitive function. We examined whether CANTAB tests measured specific cognitive functions, using established neuropsychological tests as a reference point. A sample of 500 healthy older (M = 60.28 years, SD = 6.75) participants in the Tasmanian Healthy Brain Project completed battery of CANTAB subtests and standard paper-based neuropsychological tests. Confirmatory factor analysis identified four factors: processing speed, verbal ability, episodic memory, and working memory. However, CANTAB tests did not consistently load onto the cognitive domain factors derived from traditional measures of the same function. These results indicate that five of the six CANTAB subtests examined did not load onto single cognitive functions. These CANTAB tests may lack the sensitivity to measure discrete cognitive functions in healthy populations or may measure other cognitive domains not included in the traditional neuropsychological battery.

  6. A survey on worries of pregnant women - testing the German version of the Cambridge Worry Scale

    PubMed Central

    2009-01-01

    Background Pregnancy is a transition period in a woman's life characterized by increased worries and anxiety. The Cambridge Worry Scale (CWS) was developed to assess the content and extent of maternal worries in pregnancy. It has been increasingly used in studies over recent years. However, a German version has not yet been developed and validated. The aim of this study was (1) to assess the extent and content of worries in pregnancy on a sample of women in Germany using a translated and adapted version of the Cambridge Worry Scale, and (2) to evaluate the psychometric properties of the German version. Methods We conducted a cross-sectional study and enrolled 344 pregnant women in the federal state of Baden-Württemberg, Germany. Women filled out structured questionnaires that contained the CWS, the Spielberger-State-Trait-Anxiety Inventory (STAI), as well as questions on their obstetric history. Antenatal records were also analyzed. Results The CWS was well understood and easy to fill in. The major worries referred to the process of giving birth (CWS mean value 2.26) and the possibility that something might be wrong with the baby (1.99), followed by coping with the new baby (1.57), going to hospital (1.29) and the possibility of going into labour too early (1.28). The internal consistency of the scale (0.80) was satisfactory, and we found a four-factor structure, similar to previous studies. Tests of convergent validity showed that the German CWS represents a different construct compared with state and trait anxiety but has the desired overlap. Conclusions The German CWS has satisfactory psychometric properties. It represents a valuable tool for use in scientific studies and is likely to be useful also to clinicians. PMID:20038294

    Introduction The Cambridge Water Department (CWD) supplies about 15 million gallons of water each day to more than 95,000 customers in the City of Cambridge, Massachusetts. Most of this water is obtained from a system of reservoirs located in Cambridge and in parts of five other suburban-Boston communities. The drainage basin that contributes water to these reservoirs includes several potential sources of drinking-water contaminants, including major highways, secondary roads, areas of commercial and industrial development, and suburban residential tracts. The CWD is implementing a comprehensive Source-Water Protection Plan to ensure that the highest quality water is delivered to the treatment plant. A key element of this plan is a program that combines systematic monitoring of the drainage basin with detailed investigations of the effects of nonpoint-source contaminants, such as highway-deicing chemicals, nutrients, oxygen-demanding organic compounds, bacteria, and trace metals arising from stormwater runoff. The U.S. Geological Survey (USGS) is working with the CWD and the Massachusetts Highway Department (MassHighway) to develop a better understanding of the sources, transport, and fate of many of these contaminants. This Fact Sheet describes source-water protection and water-quality investigations currently underway in the Cambridge drinking-water supply system. The investigations are designed to complement a national effort by the USGS to provide water suppliers and regulatory agencies with information on the vulnerability of water supplies and the movement and fate of source-water contaminants.

    Conformations of the crystalline 3,3,3-trifluoro-2-methoxy-2-phenylpropanamide derivatives (MTPA amides) deposited in the Cambridge Structural Database (CSD) were examined statistically as Racid-enantiomers. The majority of dihedral angles (48/58, ca. 83%) of the amide carbonyl groups and the trifluoromethyl groups ranged from -30° to 0° with an average angle ?1 of -13°. The other conformational properties were also clarified: (1) one of the fluorine atoms was antiperiplanar (ap) to the amide carbonyl group, forming a staggered conformation; (2) the MTPA amides prepared from primary amines showed a Z form in amide moieties; (3) in the case of the MTPA amide prepared from a primary amine possessing secondary alkyl groups (i.e., Mosher-type MTPA amide), the dihedral angles between the methine groups and the carbonyl groups were syn and indicative of a moderate conformational flexibility; (4) the phenyl plane was inclined from the O-Cchiral bond of the methoxy moiety with an average dihedral angle ?2 of +21°; (5) the methyl group of the methoxy moiety was ap to the ipso-carbon atom of the phenyl group.

    Dispersion of particles, as evidenced by changes in their number distributions (PNDs) and concentrations (PNCs), in urban street canyons, is still not well understood. This study compares measurements by a fast-response particle spectrometer (DMS500) of the PNDs and the PNCs (5-1000 nm, sampled at 1 Hz) at street and rooftop levels in a Cambridge UK street canyon, and examines mixing, physical and chemical conversion processes, and the competing influences of traffic volume and rooftop wind speed on the PNDs and the PNCs in various size ranges. PNCs at street level were ≈6.5 times higher than at rooftop. Street-level PNCs followed the traffic volume and decreased with increasing wind speed, showing a larger influence of wind speed on 30-300 nm particles than on 5-30 nm particles. Conversely, rooftop PNCs in the 5-30 nm size range increased with wind speed, whereas those for particles between 30 and 300 nm did not vary with wind speed.

    The daily monitoring of short time intensity fluctuations of astronomical radio sources by an array at the Mullard Radio Astronomy Observatory (MRAO), Cambridge, provides one of the few remote sensing techniques for studying the large scale structure of the near-Earth heliosphere. It has the potential to provide a forecast of interplanetary conditions upstream of the Earth. The array, which operates at 81.5 MHz, was refurbished in 1989/1990 and observations of the 0.5 AU to greater than 1 AU heliopsphere are now available for over 2 years of essentially continuous operation. After an introduction to the interplanetary scintillation (IPS) technique we review the overall character of the IPS results for 1991. As the coronoa is the source of the solar wind we indicate how large scale changes in the solar corona in 1991, from a near maximum to a more minimum like structure, were reflected in the IPS data. We also show, by way of a case study for two discrete events, how the MRAO IPS data may be used to investigate the solar sources and subsequent geomagnetic response to specific interplanetary plasma features.

    The Harvard Medical School-Cambridge Integrated Clerkship (HMS-CIC) is a redesign of the principal clinical year to foster students' learning from close and continuous contact with cohorts of patients in the disciplines of internal medicine, neurology, obstetrics-gynecology, pediatrics, and psychiatry. With year-long mentoring, students follow their patients through major venues of care. Surgery and radiology also are taught longitudinally, grounded in the clinical experiences of a cohort of patients and in a brief immersion experience working directly with an attending surgeon. Students participate in weekly, case-based tutorials integrating instruction in the basic sciences with training to address the common and important issues in medicine, as identified by national organizations. In addition, they participate in a social science curriculum that focuses on self-reflection, communication skills, ethics, population sciences, and cultural competence. In the pilot year (July 2004 to July 2005), HMS-CIC students performed at least as well as traditional students in tests of content knowledge and skills, as measured by National Board of Medical Examiners (NBME) Subject Exams and the fourth-year Objective Structured Clinical Exam, and they scored higher on a year-end comprehensive clinical skills self-assessment examination, suggesting that they retained content knowledge better. From surveys, HMS-CIC students were much more likely to see patients before diagnosis and after discharge and to receive feedback and mentoring from experienced faculty than were their traditionally educated peers. HMS-CIC students expressed more satisfaction with their curriculum and felt better prepared to cope with the professional challenges of patient care, such as being truly caring, involving patients in decision making, and understanding how the social context affects their patients.

    Background: Restless legs syndrome also known as Willis-Ekbom's Disease (RLS/WED) is a common illness. Cambridge-Hopkins diagnostic questionnaire for RLS (CHRLSq) is a good diagnostic tool and can be used in the epidemiological studies. However, its Hindi version is not available. Thus, this study was conducted to translate and validate it in the Hindi speaking population. Materials and Methods: After obtaining the permission from the author of the CHRLSq, it was translated into Hindi language by two independent translators. After a series of forward and back translations, the finalized Hindi version was administered to two groups by one of the authors, who were blinded to the clinical diagnosis. First group consisted of RLS/WED patients, where diagnosis was made upon face to face interview and the other group — the control group included subjects with somatic symptoms disorders or exertional myalgia or chronic insomnia. Each group had 30 subjects. Diagnosis made on CHRLSq was compared with the clinical diagnosis. Statistical Analysis: Analysis was done using Statistical Package for Social Sciences (SPSS) v 21.0. Descriptive statistics was calculated. Proportions were compared using chi-square test; whereas, categorical variables were compared using independent sample t-test. Sensitivity, specificity, and positive predictive value of the translated version of questionnaire were calculated. Results: Average age was comparable between the cases and control group (RLS/WED = 39.1 ± 10.1 years vs 36.2 ± 11.4 years in controls; P = 0.29). Women outnumbered men in the RLS/WED group (87% in RLS/WED group vs 57% among controls; χ2 = 6.64; P = 0.01). Both the sensitivity and specificity of the translated version was 83.3%. It had the positive predictive value of 86.6%. Conclusion: Hindi version of CHRLSq has positive predictive value of 87% and it can be used to diagnose RLS in Hindi speaking population. PMID:26425008

    Records of water quantity, water quality, and meteorological parameters were continuously collected from three reservoirs, two primary streams, and four subbasin tributaries in the Cambridge, Massachusetts, drinking-water source area during water year 2006 (October 2005 through September 2006). Water samples were collected during base-flow conditions and storms in the subbasins of the Cambridge Reservoir and Stony Brook Reservoir drainage areas and analyzed for dissolved calcium, sodium, chloride, and sulfate; total nitrogen and phosphorus; and polar pesticides and metabolites. These data were collected to assist watershed administrators in managing the drinking-water source area and to identify potential sources of contaminants and trends in contaminant loading to the water supply. Monthly reservoir contents for the Cambridge Reservoir varied from about 59 to 98 percent of capacity during water year 2006, while monthly reservoir contents for the Stony Brook Reservoir and the Fresh Pond Reservoir was maintained at greater than 83 and 94 percent of capacity, respectively. If water demand is assumed to be 15 million gallons per day by the city of Cambridge, the volume of water released from the Stony Brook Reservoir to the Charles River during the 2006 water year is equivalent to an annual water surplus of about 127 percent. Recorded precipitation in the source area was about 16 percent greater for the 2006 water year than for the previous water year and was between 12 and 73 percent greater than for any recorded amount since water year 2002. The monthly mean specific-conductance values for all continuously monitored stations within the drinking-water source area were generally within the range of historical data collected since water year 1997, and in many cases were less than the historical medians. The annual mean specific conductance of 738 uS/cm (microsiemens per centimeter) for water discharged from the Cambridge Reservoir was nearly identical to the annual mean specific conductance for water year 2005 which was 737 uS/cm. However, the annual mean specific conductance at Stony Brook near Route 20 in Waltham (U.S. Geological Survey (USGS) station 01104460), on the principal tributary to the Stony Brook Reservoir, and at USGS station 01104475 on a smaller tributary to the Stony Brook Reservoir were about 15 and 13 percent lower, respectively, than the previous annual mean specific conductances of 538 and 284 uS/cm, respectively for water year 2005. The annual mean specific conductance for Fresh Pond Reservoir decreased from 553 uS/cm in the 2005 water year to 514 uS/cm in the 2006 water year. Water samples were collected in nearly all of the subbasins in the Cambridge drinking-water source area and from Fresh Pond during water year 2006. Discrete water samples were collected during base-flow conditions with an antecedent dry period of at least 4 days. Composite samples, consisting of as many as 100 subsamples, were collected by automatic samplers during storms. Concentrations of most dissolved constituents were generally lower in samples of stormwater than in samples collected during base flow; however, the average concentration of total phosphorus in samples of stormwater were from 160 to 1,109 percent greater than the average concentration in water samples collected during base-flow conditions. Concentrations of total nitrogen in water samples collected during base-flow conditions and composite samples of stormwater at USGS stations 01104415, 01104460, and 01104475 were similar, but mean concentrations of total nitrogen in samples of stormwater differed by about 0.5 mg/L (milligrams per liter) from those in water samples collected during base-flow conditions at U.S. Geological Survey stations 01104433 and 01104455. In six water samples, measurements of pH were lower than the U.S. Environmental Protection Agency (USEPA) national recommended freshwater quality criteria and the USEPA secondary drinking water-standa

    Low frequency radio astronomy in Tasmania began with the arrival of Grote Reber to the State in 1954. After analysing ionospheric data from around the world, he concluded that Tasmania would be a very suitable place to carry out low frequency observations. Communications with Graeme Ellis in Tasmania, who had spent several years studying the ionosphere, led to a collaboration between the two in 1955 during which year they made observations at Cambridge, near Hobart. Their observations took place at four frequencies between 2.13 MHz and 0.52 MHz inclusive, with the results at the higher frequencies revealing a clear celestial component

    Face recognition ability follows a lengthy developmental course, not reaching maturity until well into adulthood. Valid and reliable assessments of face recognition memory ability are necessary to examine patterns of ability and disability in face processing, yet there is a dearth of such assessments for children. We modified a well-known test of face memory in adults, the Cambridge Face Memory Test (Duchaine & Nakayama, 2006, Neuropsychologia, 44, 576-585), to make it developmentally appropriate for children. To establish its utility, we administered either the upright or inverted versions of the computerised Cambridge Face Memory Test - Children (CFMT-C) to 401 children aged between 5 and 12 years. Our results show that the CFMT-C is sufficiently sensitive to demonstrate age-related gains in the recognition of unfamiliar upright and inverted faces, does not suffer from ceiling or floor effects, generates robust inversion effects, and is capable of detecting difficulties in face memory in children diagnosed with autism. Together, these findings indicate that the CFMT-C constitutes a new valid assessment tool for children's face recognition skills. PMID:25054837

    Intensive cisplatin and oral etoposide for relapsed epithelial ovarian cancer (EOC), commonly known as the van der Burg (VDB) protocol, has been reported to improve response rates and progression-free survival. We report on all patients with relapsed EOC treated on the VDB protocol at the Cambridge Gynae-Oncology Centre. From the institutional databases, we identified all patients treated since 2001. We extracted demographic, clinical, treatment, and toxicity data and outcomes. We used Cox regression to identify predictors of survival. A total of 35 patients were treated on the VDB protocol. Toxicity was significant, with grade 3/4 fatigue, nausea and vomiting affecting 46, 46 and 29% of patients, respectively. Six patients had grade 3/4 infection and four (11%) deaths occurred on treatment. Efficacy was encouraging, with a radiological response rate of 43%, a median progression-free survival of 5.8 months and a median overall survival of 14.1 months. No significant difference in efficacy was seen between platinum-resistant and sensitive patients. We report significant activity of the VDB protocol in a routine clinical setting. However, the high rates of serious toxicity and treatment-related deaths among patients treated with palliative intent proved unacceptable. The Cambridge Gynae-Oncology Centre no longer uses this regimen in women with relapsed EOC. PMID:26575000

    Records of water quantity, water quality, and meteorological parameters were continuously collected from three reservoirs, two primary streams, and four subbasin tributaries in the Cambridge, Massachusetts, drinking-water source area during water year 2005 (October 2004 through September 2005). Water samples were collected during base-flow conditions and storms in the subbasins of the Cambridge Reservoir and Stony Brook Reservoir drainage areas and analyzed for selected elements, organic constituents, suspended sediment, and Escherichia coli bacteria. These data were collected to assist watershed administrators in managing the drinking-water source area and to identify potential sources of contaminants and trends in contaminant loading to the water supply. Monthly reservoir capacities for the Cambridge Reservoir varied from about 59 to 98 percent during water year 2005, while monthly reservoir capacities for the Stony Brook Reservoir and the Fresh Pond Reservoir were maintained at capacities greater than 84 and 96 percent, respectively. Assuming a water demand of 15 million gallons per day by the city of Cambridge, the volume of water released from the Stony Brook Reservoir to the Charles River during the 2005 water year is equivalent to an annual water surplus of about 119 percent. Recorded precipitation in the source area for the 2005 water year was within 2 inches of the total annual precipitation for the previous 2 water years. The monthly mean specific conductances for the outflow of the Cambridge Reservoir were similar to historical monthly mean values. However, monthly mean specific conductances for Stony Brook near Route 20, in Waltham (U.S. Geological Survey station 01104460), which is the principal tributary feeding the Stony Brook Reservoir, were generally higher than the medians of the monthly mean specific conductances for the period of record. Similarly, monthly mean specific conductances for a small tributary to Stony Brook (U.S. Geological Survey station 01104455) were generally higher than the medians of the monthly mean specific conductances for the period of record. The annual mean specific conductance for Fresh Pond Reservoir increased from 514 microsiemens per centimeter (?S/cm) in the 2004 water year to 553 ?S/cm for the 2005 water year. Water samples were collected from four tributaries during base-flow and stormflow conditions in December 2004, and July, August, and September 2005 and analyzed for suspended sediment, 6 major dissolved ions, total nitrogen, total phosphorus, 8 total metals, 18 polyaromatic hydrocarbons (PAHs), 61 pesticides and metabolites, and Escherichia coli bacteria. Concentrations for most dissolved constituents in samples of stormwater were generally lower than the concentrations observed in samples collected during base flow; however, concentrations of total phosphorus, PAHs, suspended sediment, and some total recoverable metals were substantially greater in stormwater samples. Concentrations of dissolved chloride and total recoverable manganese in water samples collected during base-flow conditions from three tributaries exceeded the U.S. Environmental Protection Agency (USEPA) secondary drinking water standards of 250 and 0.05 milligrams per liter (mg/L), respectively. Concentrations of total recoverable manganese exceeded the secondary drinking water standard in samples of stormwater from each tributary. Concentrations of total recoverable iron in water samples exceeded the (USEPA) secondary drinking water standard of 0.3 mg/L periodically in water samples collected at (USEPA) stations 01104415, 01104455, and 01104475, and consistently in all water samples collected at USGS station 01104433. Concentrations of Escherichia coli bacteria in water samples collected during base flow ranged from 4 to 1,400 colony-forming units per 100 milliliters (col/100mL). Concentrations of Escherichia coli bacteria in composite samples of stormwater ranged between 1,700 to 43,000 c

    The purpose of the MIT (Massachusetts Institute of Technology) jar tests of chitosan using CWD (Cambridge Water Department Treatment Plant) water was to demonstrate the effectiveness of chitosan as a coagulant in drinking water applications. The approach was to compare the performance of the natural organic coagulant, chitosan, to the performance of alum and other chemical coagulants in terms of the parameters turbidity, color, pH and alkalinity. Twenty-five jar tests were conducted during November and December, 1992, at Parsons Laboratory, MIT, Cambridge, Massachusetts.

    Car use is associated with substantial health and environmental costs but research in deprived populations indicates that car access may also promote psychosocial well-being within car-oriented environments. This mixed-method (quantitative and qualitative) study examined this issue in a more affluent setting, investigating the socio-economic structure of car commuting in Cambridge, UK. Our analyses involved integrating self-reported questionnaire data from 1142 participants in the Commuting and Health in Cambridge study (collected in 2009) and in-depth interviews with 50 participants (collected 2009–2010). Even in Britain's leading ‘cycling city’, cars were a key resource in bridging the gap between individuals' desires and their circumstances. This applied both to long-term life goals such as home ownership and to shorter-term challenges such as illness. Yet car commuting was also subject to constraints, with rush hour traffic pushing drivers to start work earlier and with restrictions on, or charges for, workplace parking pushing drivers towards multimodal journeys (e.g. driving to a ‘park-and-ride’ site then walking). These patterns of car commuting were socio-economically structured in several ways. First, the gradient of housing costs made living near Cambridge more expensive, affecting who could ‘afford’ to cycle and perhaps making cycling the more salient local marker of Bourdieu's class distinction. Nevertheless, cars were generally affordable in this relatively affluent, highly-educated population, reducing the barrier which distance posed to labour-force participation. Finally, having the option of starting work early required flexible hours, a form of job control which in Britain is more common among higher occupational classes. Following a social model of disability, we conclude that socio-economic advantage can make car-oriented environments less disabling via both greater affluence and greater job control, and in ways manifested across the full socio-economic range. This suggests the importance of combining individual-level ‘healthy travel’ interventions with measures aimed at creating travel environments in which all social groups can pursue healthy and satisfying lives.

  5. Commuting and health in Cambridge: a study of a 'natural experiment' in the provision of new transport infrastructure

    PubMed Central

    2010-01-01

    Background Modifying transport infrastructure to support active travel (walking and cycling) could help to increase population levels of physical activity. However, there is limited evidence for the effects of interventions in this field, and to the best of our knowledge no study has convincingly demonstrated an increase in physical activity directly attributable to this type of intervention. We have therefore taken the opportunity presented by a 'natural experiment' in Cambridgeshire, UK to establish a quasi-experimental study of the effects of a major transport infrastructural intervention on travel behaviour, physical activity and related wider health impacts. Design and methods The Commuting and Health in Cambridge study comprises three main elements: a cohort study of adults who travel to work in Cambridge, using repeated postal questionnaires and basic objective measurement of physical activity using accelerometers; in-depth quantitative studies of physical activity energy expenditure, travel and movement patterns and estimated carbon emissions using household travel diaries, combined heart rate and movement sensors and global positioning system (GPS) receivers; and a longitudinal qualitative interview study to elucidate participants' attitudes, experiences and practices and to understand how environmental and social factors interact to influence travel behaviour, for whom and in what circumstances. The impacts of a specific intervention - the opening of the Cambridgeshire Guided Busway - and of other changes in the physical environment will be examined using a controlled quasi-experimental design within the overall cohort dataset. Discussion Addressing the unresolved research and policy questions in this area is not straightforward. The challenges include those of effectively combining different disciplinary perspectives on the research problems, developing common methodological ground in measurement and evaluation, implementing robust quantitative measurement of travel and physical activity behaviour in an unpredictable 'natural experiment' setting, defining exposure to the intervention, defining controls, and conceptualising an appropriate longitudinal analytical strategy.

  6. A comparison of three infant skinfold reference standards: Tanner-Whitehouse, Cambridge Infant Growth Study, and WHO Child Growth Standards.

    2015-10-01

    As researchers increasingly focus on early infancy as a critical period of development, there is a greater need for methodological tools that can address all aspects of infant growth. Infant skinfold measures, in particular, are measurements in need of reliable reference standards that encompass all ages of infants and provide an accurate assessment of the relative fatness of a population. This report evaluates three published reference standards for infant skinfold measurements: Tanner-Whitehouse, Cambridge Infant Growth Study, and the World Health Organization (WHO) Child Growth Standards. To assess these standards, triceps skinfolds from a population of rural Kenyan infants (n?=?250) and triceps skinfolds and subscapular skinfolds from infants in the National Health and Nutrition Examination Survey 1999-2002 (NHANES; n?=?1197) were calculated as z-scores from the lambda-mu-sigma curves provided by each reference population. The Tanner-Whitehouse standards represented both the Kenyan and US populations as lean, while the Cambridge standards represented both populations as overfat. The distribution of z-scores based on the WHO standards fell in the middle, but excluded infants from both populations who were below the age of 3 months. Based on these results, the WHO reference standard is the best skinfold reference standard for infants over the age of 3 months. For populations with infants of all ages, the Tanner-Whitehouse standards are recommended, despite representing both study populations as underfat. Ideally, the WHO will extend their reference standard to include infants between the ages of 0 and 3 months. PMID:24521298

  17. Shuttle Astronauts Visit NASA's X-Ray Observatory Operations Control Center in Cambridge to Coordinate Plans for Launch

    NASA Astrophysics Data System (ADS)

    1998-06-01

    CAMBRIDGE, MASS.-- June 25, 1998 Eileen Collins, the first U.S. woman commanderof a Space Shuttle mission and her fellow astronauts for NASA s STS-93 mission toured the Operations Control Center (OCC) for the Advanced X-ray Astrophysics Facility (AXAF) today. AXAF is scheduled for launch on January 26, 1999 aboard the Space Shuttle Columbia. They met with the staff of the OCC and discussed how the status of the observatory will be monitored while in the shuttle bay and during deployment. "We are honored to have this historic shuttle crew visit us and familiarize themselves with the OCC," said Harvey Tananbaum, director of the AXAF Science Center, which operates the OCC for the Smithsonian Astrophysical Observatory through a contract with NASA's Marshall Space Flight Center. "It is appropriate that a pathbreaking shuttle mission will deploy the premier X-ray observatory of this century." AXAF is the third of NASA s Great Observatories along with the Hubble Space Telescope and the Compton Gamma Ray Observatory. It will observe in greater detail than ever before the hot, violent regions of the universe that cannot be seen with optical telescopes. Exploding stars, black holes and vast clouds of gas in galaxy clusters are among the fascinating objects that AXAF is designed to study. The satellite is currently in the final stages of testing at TRW Space and Electronics Group,the prime contractor, in Redondo Beach, California. In late August it will be flown aboard a specially-outfitted Air Force C-5 aircraft to Kennedy Space Center in Florida where it will be integrated with a Boeing booster and then installed in the Shuttle bay. The shuttle crew that will take AXAF into space includes Collins (Col., USAF), Jeffrey Ashby (Cmdr., USN), pilot; Steven Hawley, Ph.D., mission specialist; Catherine Cady Coleman, Ph.D. (Major, USAF), mission specialist; and Michel Tognini (Col., French Air Force), mission specialist. While visiting the OCC the crew learned how critical data (temperatures, voltages, etc.,) will be monitored while AXAF is in the bay of the shuttle. This information will be relayed to the shuttle from the OCC via Johnson Space Center. The condition of the satellite during launch and the first few orbits will determine if it can be sent on its way. Unlike the Hubble Space telescope, AXAF will not be serviceable after it is in orbit. When the satellite has been released into space from the shuttle bay, a built in propulsion system will boost it into a large elliptical orbit around Earth. The nearest the observatory will come to Earth is 6,200 miles and its furthest point will be more than a third of the way to the moon. This means that the telescope will have approximately 52 hours of observing time each orbit. AXAF images will show fifty times more detail than any previous X-ray telescope. The revolutionary telescope combines the ability to make sharp images while measuring precisely the energies of X-rays coming from cosmic sources. The impact AXAF will have on X-ray astronomy can be compared to the difference between a fuzzy black and white and a sharp color picture.

    Evolutionary theory is one of the most widely misunderstood and consistently rejected concepts in the whole of science. In Understanding Evolution, Kostas Kampourakis investigates the psychological dimensions of this popular discontent with evolutionary theory. At the heart of this persisting public disenchantment with the theory lies the thoroughly counterintuitive, even alien, nature of biological evolution. Historically, people have rejected evolution on religious, ethical, and existential grounds, but there is a psychological component to our aversion to evolution. It simply does not resonate with human expectations about how the world should work. Kampourakis does an excellent job presenting evolutionary theory and summarizing the evidence for it. Ultimately, he argues that in spite of powerful emotional and instinctual forces arrayed against it, we have much to gain by allowing the evolutionary picture to enrich our understanding of the world. If we allow the full drama of the history of life on Earth to present itself to us, we can place ourselves within that drama and find ways to relate it meaningfully to our lives without psychological barriers mounted by disdain and discomfort.

    2015-01-01

    Pyrylium salts are a very important class of organic molecules containing a trivalent oxygen atom in a six-membered aromatic ring. In this manuscript, we report a theoretical study of pyrylium salts and their thio-, seleno- and telluro- analogues by means of DFT calculations. For this purpose, unsubstituted 2,4,6-trimethyl and 2,4,6-triphenyl cations and anions with different morphologies were chosen (Cl-, NO3- and BF4-). The complexes were characterized by means of natural bond orbital and "atoms-in-molecules" theories, and the physical nature of the interactions has been analyzed by means of symmetry-adapted perturbation theory calculations. Our results indicate the presence of anion-? interactions and chalcogen bonds based on both ?- and ?-hole interactions and the existence of very favorable ?-complexes, especially for unsubstituted cations. The electrostatic component is dominant in the interactions, although the induction contributions are important, particularly for chloride complexes. The geometrical features of the complexes have been compared with experimental data retrieved from the Cambridge Structural Database. PMID:26114926

  20. Conformer Generation with OMEGA: Algorithm and Validation Using High Quality Structures from the Protein Databank and Cambridge Structural Database

    PubMed Central

    2010-01-01

    Here, we present the algorithm and validation for OMEGA, a systematic, knowledge-based conformer generator. The algorithm consists of three phases: assembly of an initial 3D structure from a library of fragments; exhaustive enumeration of all rotatable torsions using values drawn from a knowledge-based list of angles, thereby generating a large set of conformations; and sampling of this set by geometric and energy criteria. Validation of conformer generators like OMEGA has often been undertaken by comparing computed conformer sets to experimental molecular conformations from crystallography, usually from the Protein Databank (PDB). Such an approach is fraught with difficulty due to the systematic problems with small molecule structures in the PDB. Methods are presented to identify a diverse set of small molecule structures from cocomplexes in the PDB that has maximal reliability. A challenging set of 197 high quality, carefully selected ligand structures from well-solved models was obtained using these methods. This set will provide a sound basis for comparison and validation of conformer generators in the future. Validation results from this set are compared to the results using structures of a set of druglike molecules extracted from the Cambridge Structural Database (CSD). OMEGA is found to perform very well in reproducing the crystallographic conformations from both these data sets using two complementary metrics of success. PMID:20235588

    Quantifying the structural order in amorphous and partially ordered solids, and the effects of such order on solid-state properties, has been a longstanding challenge in the fields of amorphous glasses, semiconductors, and metals. Significant new understanding has emerged during the past few years thanks to advances in experimental techniques, theoretical approaches, and simulation of structure and properties. The International Conference on Nanoscale Order in Amorphous and Partially Ordered Solids was held at Trinity College, Cambridge UK on July 9-11, 2007. The intent of the workshop was to bring together leading researchers from around the world to report their recent work, discuss the state of the field, and chart future directions. These interactions took place formally via 21 oral and 21 poster presentations, and informally via walks in the Fellows Garden and of course in the pubs of Cambridge. We believe that we speak for all the participants in declaring the conference a great success. The meeting was supported by the FEI company, the US National Science Foundation and Trinity College Cambridge; we are very grateful for their generous support. We would also like to thank the staff and publishers of Journal of Physics: Condensed Matter for their assistance and efficiency in producing this volume.

    It was a great pleasure and an honor for us to host the 12th Gravitational Wave Data Analysis Workshop (GWDAW) at MIT and the LIGO Laboratory in Cambridge, Massachusetts, the place where this workshop series started in 1996. This time the conference was held at the conference facilities of the Royal Sonesta Hotel in Cambridge from 13 16 December, 2007. This 12th GWDAW found us with the ground interferometers having just completed their most sensitive search for gravitational waves and as they were starting their preparation to bring online and/or propose more sensitive instruments. Resonant mass detectors continued to observe the gravitational wave sky with instruments that have been operating now for many years. LISA, the Laser Interferometer Space Antenna, was recently reviewed by NASA's Beyond Einstein Program Assessment Committee (BEPAC) convened by the National Research Council (NRC) and found that 'on purely scientific grounds LISA is the mission that is the most promising and least scientifically risky…thus, the committee gave LISA its highest scientific ranking'. Even so, JDEM, the Joint Dark Energy Mission, was identified to go first, with LISA following a few years after. New methods, analysis ideas, results from the analysis of data collected by the instruments, as well as Mock Data Challenges for LISA were reported in this conference. While data from the most recent runs of the instruments are still being analyzed, the first upper limit results show how even non-detection statements can be interesting astrophysics. Beyond these traditional aspects of GWDAW though, for the first time in this workshop we tried to bring the non-gravitational wave physics and astronomy community on board in order to present, discuss and propose ways to work together as we pursue the first detection of gravitational waves and as we hope to transition to gravitational wave astronomy in the near future. Overview talks by colleagues leading observations in the electromagnetic and particle spectrum, from what is expected to be common sources of gravitational and electromagnetic radiation as well as neutrinos, have created great excitement, lively discussions and have given birth to collaborations for joint analyses and observations. A special thank you to our non-gravitational wave presenters and participants for making the time to join us. We hope this will be the beginning of a long tradition for this workshop. In this workshop we also introduced the student prize for the best poster. Twenty student posters participated in this competition. Pinkesh Patel of Caltech was the prize winner on a 'Resampling Technique to Calculate the F-statistic', co-authored with X Siemens and R Dupuis. We are grateful to the MIT Kavli Institute for providing the financial support for the cash prize that accompanied this. We would like to thank the local and international organizing committees for putting together a great scientific program, all the conference presenters and participants and finally the CQG editorial staff for making this conference proceeding volume happen.

  6. Potential reductions of street solids and phosphorus in urban watersheds from street cleaning, Cambridge, Massachusetts, 2009-11

    USGS Publications Warehouse

    Sorenson, Jason R.

    2013-01-01

    Material accumulating and washing off urban street surfaces and ultimately into stormwater drainage systems represents a substantial nonpoint source of solids, phosphorus, and other constituent loading to waterways in urban areas. Cost and lack of usable space limit the type and number of structural stormwater source controls available to municipalities and other public managers. Non-structural source controls such as street cleaning are commonly used by cities and towns for construction, maintenance and aesthetics, and may reduce contaminant loading to waterways. Effectiveness of street cleaning is highly variable and potential improvements to water quality are not fully understood. In 2009, the U.S. Geological Survey, in cooperation with the Massachusetts Department of Environmental Protection, the U.S. Environmental Protection Agency, and the city of Cambridge, Massachusetts, and initiated a study to better understand the physical and chemical nature of the organic and inorganic solid material on street surfaces, evaluate the performance of a street cleaner at removing street solids, and make use of the Source Loading and Management Model (SLAMM) to estimate potential reductions in solid and phosphorus loading to the lower Charles River from various street-cleaning technologies and frequencies. Average yield of material on streets collected between May and December 2010, was determined to be about 740 pounds per curb-mile on streets in multifamily land use and about 522 pounds per curb-mile on commercial land-use streets. At the end-of-winter in March 2011, about 2,609 and 4,788 pounds per curb-mile on average were collected from streets in multifamily and commercial land-use types, respectively. About 86 percent of the total street-solid yield from multifamily and commercial land-use streets was greater than or equal to 0.125 millimeters in diameter (or very fine sand). Observations of street-solid distribution across the entire street width indicated that as much as 96 percent of total solids resided within 9 feet of the curb. Median accumulation rates of street solids and median washoff of street solids after rainstorms on multifamily and commercial land-use streets were also similar at about 33 and 22 pounds per curb-mile per day, and 35 and 40 percent, respectively. Results indicate that solids on the streets tested in Cambridge, Mass., can recover to pre-rainstorm yields within 1 to 3 days after washoff. The finer grain-size fractions tended to be more readily washed from the roadway surfaces during rainstorms. Street solids in the coarsest grain-size fraction on multifamily streets indicated an average net increase following rainstorms and are likely attributed to debris run-on from trees, lawns, and other plantings commonly found in residential areas. In seven experiments between May and December 2010, the median removal efficiency of solids from street surfaces following a single pass by a regenerative-air street cleaner was about 82 percent on study sites in the multifamily land-use streets and about 78 percent on the commercial land-use streets. Median street-solid removal efficiency increased with increasing grain size. This type of regenerative-air street cleaner left a median residual street-solid load on the street surface of about 100 pounds per curb-mile. Median concentrations of organic carbon and total phosphorus (P) on multifamily streets were about 35 and 29 percent greater, respectively, than those found on commercial streets. The median total mass of organic carbon and total P in street solids on multifamily streets was 68 and 75 percent greater, respectively, than those found on commercial streets. More than 87 percent of the mass of total P was determined to be in solids greater than or equal to 0.125 millimeters in diameter for both land-use types. The median total accumulation rate for total P on multifamily streets was about 5 times greater than on commercial streets. Total P accumulation in the medium grain-size fraction was nearly the same for streets within both land-use types at 0.004 pounds per curb-mile per day. Accumulation rates within the coarsest and finest grain-size fractions on multifamily streets were about 11 and 82 times greater than those on the commercial streets. Median washoff of total P was 58 and 48 percent from streets in multifamily and commercial land-use types, respectively, and generally increased with decreasing grain size. Total P median reductions resulting from a single pass of a regenerative-air street cleaner on streets in multifamily and commercial land-use types were about 82 and 62 percent, respectively, and were similar in terms of grain size between both land-use types. A Source Loading and Management Model for Microsoft Windows (WinSLAMM) was applied to a 21.8 acre subcatchment in Cambridge, Mass. The subcatchment area consists of mostly commercial and multifamily land-use types to evaluate the potential reductions of total and particulate solids, and P attributed to street cleaning. Rainwater runoff from rooftops represented between 20 and 50 percent of the total basin runoff. Street surfaces only accounted for about 20 percent of the total basin runoff. Monthly applications of mechanical-brush and vacuum-assisted street cleaners within the subcatchment as defined by SLAMM for areas with long-term (24-hour) on-street parking and monthly parking controls using five average climatic years resulted in total solid reductions of about 3 and 5 percent, respectively. Simulating the regenerative-air street cleaner tested as part of this study resulted in total solid reductions of about 16 percent. Increasing street cleaning frequency to three times weekly increased total solids removal for mechanical-brush, vacuum-assisted, and regenerative-air street cleaners to about 6, 14, and 19 percent, respectively. Monthly applications of mechanical-brush, vacuum-assisted, and regenerative-air street cleaners within the subcatchment resulted in total P reductions of about 1, 3, and 8 percent, respectively. A street cleaning frequency of three times each week for each of the three street-cleaner types increased total P removal to about 3, 7, and 9 percent, respectively.

    The revived interest in halogen bonding as a tool in pharmaceutical cocrystals and drug design has indicated that cyano-halogen interactions could play an important role. The crystal structures of four closely related ?-keto esters, which differ only in the substitution at a single C atom (by H, OMe, Cl and Br), are compared, namely ethyl 2-cyano-5-oxo-5-phenyl-3-(piperidin-1-yl)pent-2-enoate, C19H22N2O3, (1), ethyl 2-cyano-5-(4-methoxyphenyl)-5-oxo-3-(piperidin-1-yl)pent-2-enoate, C20H24N2O4, (2), ethyl 5-(4-chlorophenyl)-2-cyano-5-oxo-3-(piperidin-1-yl)pent-2-enoate, C19H21ClN2O3, (3), and the previously published ethyl 5-(4-bromophenyl)-2-cyano-5-oxo-3-(piperidin-1-yl)pent-2-enoate, C19H21BrN2O3, (4) [Maurya, Vasudev & Gupta (2013). RSC Adv. 3, 12955-12962]. The molecular conformations are very similar, while there are differences in the molecular assemblies. Intermolecular C-H...O hydrogen bonds are found to be the primary interactions in the crystal packing and are present in all four structures. The halogenated derivatives have additional aromatic-aromatic interactions and cyano-halogen interactions, further stabilizing the molecular packing. A database analysis of cyano-halogen interactions using the Cambridge Structural Database [CSD; Groom & Allen (2014). Angew. Chem. Int. Ed. 53, 662-671] revealed that about 13% of the organic molecular crystals containing both cyano and halogen groups have cyano-halogen interactions in their packing. Three geometric parameters for the C-X...N[triple-bond]C interaction (X = F, Cl, Br or I), viz. the N...X distance and the C-X...N and C-N...X angles, were analysed. The results indicate that all the short cyano-halogen contacts in the CSD can be classified as halogen bonds, which are directional noncovalent interactions. PMID:26422224

    This report provides the results of a detailed Level II analysis of scour potential at structure CAMBTH00750053 on Town Highway 75 crossing the Brewster River, Cambridge, 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 northwestern Vermont. The 4.30-mi2 drainage area is in a predominantly rural and forested basin. In the vicinity of the study site, the surface cover is forest, except for the downstream right overbank area which has a barn surrounded by grass and shrubs. In the study area, the Brewster River has an incised, straight channel with a slope of approximately 0.05 ft/ft, an average channel top width of 62 ft and an average bank height of 12 ft. The channel bed material ranges from gravel to boulder with a median grain size (D50) of 84.4 mm (0.277 ft). The geomorphic assessment at the time of the Level I and Level II site visit on July 11, 1995, indicated that the reach was stable. The Town Highway 75 crossing of the Brewster River is a 28-ft-long, two-lane bridge consisting of one 24-foot concrete tee-beam span (Vermont Agency of Transportation, written communication, March 8, 1995). The opening length of the structure parallel to the bridge face is 22.4 ft. The bridge is supported by vertical, concrete abutments with wingwalls. The channel is skewed approximately 40 degrees to the opening while the opening-skew-to-roadway as surveyed is 10 degrees. A scour hole 1 ft deeper than the mean thalweg depth was observed along the left abutment during the Level I assessment. The scour counter-measures at the site included type-3 stone fill (less than 48 inches diameter) along the entire base length of the upstream left wingwall. There was also type-4 stone fill (less than 60 inches diameter) along the downstream end of the 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 1.1 to 1.4 ft. The worst-case contraction scour occurred at the 100-year discharge. Abutment scour ranged from 10.7 to 17.3 ft. The worst-case 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 including (but not limited to) historical performance during flood events, the geomorphic stability assessment, existing scour protection measures, and the results of the hydraulic analyses. Therefore, scour depths adopted by VTAOT may differ from the computed values documented herein.

    This report presents the results of a study conducted by the U.S. Geological Survey, in cooperation with the city of Cambridge, Massachusetts, Water Department, to assess reservoir and tributary-stream quality in the Cambridge drinking-water source area, and to use the information gained to help guide the design of a comprehensive water-quality monitoring program for the source area. Assessments of the quality and trophic state of the three primary storage reservoirs, Hobbs Brook Reservoir, Stony Brook Reservoir, and Fresh Pond, were conducted (September 1997-November 1998) to provide baseline information on the state of these resources and to determine the vulnerability of the reservoirs to increased loads of nutrients and other contaminants. The effects of land use, land cover, and other drainage-basin characteristics on sources, transport, and fate of fecal-indicator bacteria, highway deicing chemicals, nutrients, selected metals, and naturally occurring organic compounds in 11 subbasins that contribute water to the reservoirs also was investigated, and the data used to select sampling stations for incorporation into a water-quality monitoring network for the source area. All three reservoirs exhibited thermal and chemical stratification, despite artificial mixing by air hoses in Stony Brook Reservoir and Fresh Pond. The stratification produced anoxic or hypoxic conditions in the deepest parts of the reservoirs and these conditions resulted in the release of ammonia nitrogen orthophosphate phosphorus, and dissolved iron and manganese from the reservoir bed sediments. Concentrations of sodium and chloride in the reservoirs usually were higher than the amounts recommended by the U.S. Environmental Protection agency for drinking-water sources (20 milligrams per liter for sodium and 250 milligrams per liter for chloride). Maximum measured sodium concentrations were highest in Hobbs Brook Reservoir (113 milligrams per liter), intermediate in Stony Brook Reservoir (62 milligrams per liter), and lowest in Fresh Pond (54 milligrams per liter). Bed sediments in Hobbs Brook and Stony Brook Reservoirs were enriched in iron, manganese, and arsenic relative to those in the impounded lower Charles River in Boston, Massachusetts. Trophic state indices, calculated for each reservoir based on nutrient concentrations, water-column transparency, and phytoplankton abundances, indicated that the upper and middle basins of Hobbs Brook Reservoir were moderately to highly productive and likely to produce algal blooms; the lower basin of Hobbs Brook Reservoir and Stony Brook Reservoir were similar and intermediate in productivity, and Fresh Pond was relatively unproductive and unlikely to produce algal blooms. This pattern is likely due to sedimentation of organic and inorganic particles in the three basins of Hobbs Brook Reservoir and in Stony Brook Reservoir. Molar ratios of nitrogen to phosphorus ranged from 55 in Stony Brook Reservoir to 120 in Hobbs Brook Reservoir, indicating that phytoplankton algae in these water bodies may be phosphorus limited and therefore sensitive to small increases in phosphorus loading from the drainage basin. Nitrogen loads were found to be less important than phosphorus to the trophic condition of the reservoirs. Hobbs Brook and Stony Brook, the two principle streams draining the Cambridge drinking-water source area, differed in their relative contributions to many of the estimated constituent loads. The estimated load of fecal coliform bacteria was more than seven times larger for the mainly residential Stony Brook subbasin upstream from Kendal Green, Mass., than it was for the more commercial and industrial Hobbs Brook subbasin, though the drainage areas of the two subbasins differ only by about 20 percent. The State standard for fecal coliform bacteria in streams in the Cambridge drinking-water source area (20 colony forming units per 100 milliliters) was exceeded at all sampling stations. Estimated s

    In this paper we call attention to the identity of the type species of Thiodina Simon, 1900, T. nicoleti Roewer, 1951. When Simon proposed the genus, he characterized it based on morphological features found in species he described, but not found in the type species he designated, and whose type specimens, apparently, he had not examined. Nicolet's original description makes it clear that the type species is not closely related to the more familiar species placed in the genus. This misinterpretation was followed by contemporary researchers and survives until today. Here we designate and describe a neotype for T. nicoleti. We revalidate Colonus F.O.P.-Cambridge, 1901 and Nilakantha Peckham & Peckham, 1901 to transfer most species formerly placed in Thiodina. The combinations Colonus puerperus (Hentz, 1846), Nilakantha cockerelli Peckham & Peckham, 1901 and N. peckhami Bryant, 1940 are restored. The following new combinations are established: Colonus branicki (Taczanowski, 1871) new comb., C. candidus (Mello-Leitão, 1922) new comb., C. germaini (Simon, 1900) new comb., C. hesperus (Richman & Vetter, 2004) new comb., C. melanogaster (Mello-Leitão, 1917) new comb., C. pallidus (C.L. Koch, 1846) new comb., C. pseustes (Chamberlin & Ivie, 1936) new comb., C. punctulatus (Mello-Leitão, 1917) new comb., C. rishwani (Makhan, 2006) new comb., C. robustus (Mello-Leitão, 1945) new comb., C. sylvanus (Hentz, 1846) new comb., C. vaccula (Simon, 1900) new comb., C. vellardi (Soares & Camargo, 1948) new comb., Nilakantha beugelorum (Wolff, 1990) new comb., N. crucifera (F.O.P.-Cambridge, 1901) new comb., and N. inerma (Bryant, 1940) new comb. Thiodina setosa Mello-Leitão, 1947 is tentatively transferred to Cotinusa Simon, 1900. PMID:26623852

  14. The Calgary-Cambridge Referenced Observation Guides: an aid to defining the curriculum and organizing the teaching in communication training programmes.

    Effective communication between doctor and patient is a core clinical skill. It is increasingly recognized that it should and can be taught with the same rigour as other basic medical sciences. To validate this teaching, it is important to define the content of communication training programmes by stating clearly what is to be learnt. We therefore describe a practical teaching tool, the Calgary-Cambridge Referenced Observation Guides, that delineates and structures the skills which aid doctor-patient communication. We provide detailed references to substantiate the research and theoretical basis of these individual skills. The guides form the foundation of a sound communication curriculum and are offered as a starting point for programme directors, facilitators and learners at all levels. We describe how these guides can also be used on an everyday basis to help facilitators teach and students learn within the experiential methodology that has been shown to be central to communication training. The learner-centred and opportunistic approach used in communication teaching makes it difficult for learners to piece together their evolving understanding of communication. The guides give practical help in countering this problem by providing: an easily accessible aide-mémoire; a recording instrument that makes feedback more systematic; and an overall conceptual framework within which to organize the numerous skills that are discovered one by one as the communication curriculum unfolds.

    Drug and alcohol dependence are global problems with substantial societal costs. There are few treatments for relapse prevention and therefore a pressing need for further study of brain mechanisms underpinning relapse circuitry. The Imperial College Cambridge Manchester (ICCAM) platform study is an experimental medicine approach to this problem: using functional magnetic resonance imaging (fMRI) techniques and selective pharmacological tools, it aims to explore the neuropharmacology of putative relapse pathways in cocaine, alcohol, opiate dependent, and healthy individuals to inform future drug development. Addiction studies typically involve small samples because of recruitment difficulties and attrition. We established the platform in three centres to assess the feasibility of a multisite approach to address these issues. Pharmacological modulation of reward, impulsivity and emotional reactivity were investigated in a monetary incentive delay task, an inhibitory control task, and an evocative images task, using selective antagonists for µ-opioid, dopamine D3 receptor (DRD3) and neurokinin 1 (NK1) receptors (naltrexone, GSK598809, vofopitant/aprepitant), in a placebo-controlled, randomised, crossover design. In two years, 609 scans were performed, with 155 individuals scanned at baseline. Attrition was low and the majority of individuals were sufficiently motivated to complete all five sessions (n=87). We describe herein the study design, main aims, recruitment numbers, sample characteristics, and explain the test hypotheses and anticipated study outputs. PMID:26246443

    Background Disordered gambling (DG) has often been associated with impaired decision-making abilities, suggesting a dysfunction in the ventromedial prefrontal cortex (vmPFC). Aims To our knowledge, no previous study has accurately considered the effect of substance use disorder (SUD) comorbidity (including nicotine dependence) on decision-making impairments in DG. Methods and Materials We employed the Cambridge Gambling Task (CGT) to assess a big cohort of patients diagnosed with DG (N = 80) against matched healthy controls (HCs) (N = 108). The cohort included DG patients with nicotine and alcohol dependence, alcohol dependence only and 12 “pure” nonsmokers with only DG diagnosis. Results Pure nonsmoking, nicotine dependent as well as alcoholic DGs with current nicotine dependence, demonstrated a decision making profile, characterized by poor decision-making abilities and failure to make right choices (rational), closely resembling that of patients with vmPFC damage. Discussion This suggests that DGs with and without SUD comorbidity are equally affected in that domain of decision making abilities. Additionally, gambling diagnosis combined with alcohol and nicotine dependence involves a group of gambling patients with a relatively riskier decision making profile, showing that these patients apart from making irrational decisions take also more risks. Our findings highlight the importance of accounting for SUD comorbidities with useful implications for future research and therapy. Limitations of the current investigation are discussed.

    Automated methods were used to search the Cambridge Crystallographic Data Files for all compounds containing C?I bonds that had C?I⋯X(O, N, S) contact distances less than 3.55 Å for O and for N, and less than 4.0 Å for S. Analysis of these data from 86 crystal structures showed that the distribution of nucleophile (O, N, S) contacts to iodine is non-spherical with the highest density and the shortest contacts (e.g., I⋯O = 2.96 Å) and C?I ⋯ X angle, ? = 180°. These data suggest that, where possible, that donor group is arranged so that one of its lone pairs is directed toward the iodine atom. Because the thyroid hormones are the only active iodine-containing compounds, C?I⋯X interactions were considered as possible contributros to enhanced protein binding affinity. In the crystal structure of the thyroxine—prealbumin complex there is a close contact between the proximal outer-ring iodine of thyroxine and the carbonyl oxygen of Ala-109A in the prealbumin backbone. The geometry of this interaction (I⋯O, 2.96 Å, C?I⋯O, 161°) is within the distribution of the iodine—oxygen interactions observed in this analysis, and suggests that this model can explain (in part) the unique role of iodine in the binding of the thyroid hormones to their specific binding proteins.

    Objective Considering the lack of studies on measures that increase the diagnostic distinction between Alzheimer's disease (AD) and mild cognitive impairment (MCI) and on the role of the Cambridge Cognitive Examination (CAMCOG) in this, our study aims to compare the utility of the CAMCOG, Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) in helping to differentiate AD from MCI in elderly people with >4 years of schooling. Method A total of 136 elderly subjects – 39 normal controls as well as 52 AD patients and 45 MCI patients treated at the Institute of Geriatrics and Gerontology, Porto Alegre, Brazil – were assessed using the MMSE, CAMCOG, clock drawing test (CDT), verbal fluency test (VF), Geriatric Depression Scale and Pfeffer Functional Activities Questionnaire. Results The results obtained by means of a receiver operating characteristic curve showed that the MoCA is a better screening test for differentiating elderly subjects with AD from those with MCI than the CAMCOG and MMSE as well as other tests such as the CDT and VF. Conclusion The MoCA, more than the CAMCOG and the other tests, was shown to be able to differentiate AD from MCI, although, as Roalf et al. [Alzheimers Dement 2013;9:529-537] pointed out, further studies might lead to measures that will improve this differentiation. PMID:24987399

    The anterior cingulate cortex (ACC), consisting of the perigenual ACC (pgACC) and mid-ACC (i.e., affective and cognitive areas, respectively), plays a significant role in the performance of gambling tasks, which are used to measure decision-making behavior under conditions of risk. Although recent neuroimaging studies have suggested that the ?-aminobutyric acid (GABA) concentration in the pgACC is associated with decision-making behavior, knowledge regarding the relationship of GABA concentrations in subdivisions of the ACC with gambling task performance is still limited. The aim of our magnetic resonance spectroscopy study is to investigate in 20 healthy males the relationship of concentrations of GABA and glutamate+glutamine (Glx) in the pgACC, mid-ACC, and occipital cortex (OC) with multiple indexes of decision-making behavior under conditions of risk, using the Cambridge Gambling Task (CGT). The GABA/creatine (Cr) ratio in the pgACC negatively correlated with delay aversion score, which corresponds to the impulsivity index. The Glx/Cr ratio in the pgACC negatively correlated with risk adjustment score, which is reported to reflect the ability to change the amount of the bet depending on the probability of winning or losing. The scores of CGT did not significantly correlate with the GABA/Cr or Glx/Cr ratio in the mid-ACC or OC. Results of this study suggest that in the pgACC, but not in the mid-ACC or OC, GABA and Glx concentrations play a distinct role in regulating impulsiveness and risk probability during decision-making behavior under conditions of risk, respectively.

    Aims To describe change in physical activity over 1 year and associations with change in cardiovascular disease risk factors in a population with screen-detected Type 2 diabetes. Methods Eight hundred and sixty-seven individuals with screen-detected diabetes underwent measurement of self-reported physical activity, cardiovascular disease risk factors and modelled cardiovascular disease risk at baseline and 1 year (n = 736) in the ADDITION-Cambridge trial. Multiple linear regression was used to quantify the association between change in different physical activity domains and cardiovascular disease risk factors at 1 year. Results There was no change in self-reported physical activity over 12 months. Even relatively large changes in physical activity were associated with relatively small changes in cardiovascular disease risk factors after allowing for changes in self-reported medication and diet. For every 30 metabolic equivalent-h increase in recreational activity (equivalent to 10 h/brisk walking/week), there was an average reduction of 0.1% in HbA1c in men (95% CI ?0.15 to ?0.01, P = 0.021) and an average reduction of 2 mmHg in systolic blood pressure in women (95% CI ?4.0 to ?0.05, P = 0.045). Conclusions Few associations were observed between change in different physical activity domains and cardiovascular disease risk factors in this trial cohort. Cardiovascular disease risk reduction appeared to be driven largely by factors other than changes in self-reported physical activity in the first year following diagnosis. PMID:22913463

    Aims To describe change in self-reported diet and plasma vitamin C, and to examine associations between change in diet and cardiovascular disease risk factors and modelled 10-year cardiovascular disease risk in the year following diagnosis of Type 2 diabetes. Methods Eight hundred and sixty-seven individuals with screen-detected diabetes underwent assessment of self-reported diet, plasma vitamin C, cardiovascular disease risk factors and modelled cardiovascular disease risk at baseline and 1 year (n = 736) in the ADDITION-Cambridge trial. Multivariable linear regression was used to quantify the association between change in diet and cardiovascular disease risk at 1 year, adjusting for change in physical activity and cardio-protective medication. Results Participants reported significant reductions in energy, fat and sodium intake, and increases in fruit, vegetable and fibre intake over 1 year. The reduction in energy was equivalent to an average-sized chocolate bar; the increase in fruit was equal to one plum per day. There was a small increase in plasma vitamin C levels. Increases in fruit intake and plasma vitamin C were associated with small reductions in anthropometric and metabolic risk factors. Increased vegetable intake was associated with an increase in BMI and waist circumference. Reductions in fat, energy and sodium intake were associated with reduction in HbA1c, waist circumference and total cholesterol/modelled cardiovascular disease risk, respectively. Conclusions Improvements in dietary behaviour in this screen-detected population were associated with small reductions in cardiovascular disease risk, independently of change in cardio-protective medication and physical activity. Dietary change may have a role to play in the reduction of cardiovascular disease risk following diagnosis of diabetes. PMID:24102972

    Background The assessment of Health Related Quality of Life (HRQL) is important in people with dementia as it could influence their care and support plan. Many studies on dementia do not specifically set out to measure dementia-specific HRQL but do include related items. The aim of this study is to explore the distribution of HRQL by functional and socio-demographic variables in a population-based setting. Methods Domains of DEMQOL’s conceptual framework were mapped in the Cambridge City over 75’s Cohort (CC75C) Study. HRQL was estimated in 110 participants aged 80+ years with a confirmed diagnosis of dementia with mild/moderate severity. Acceptability (missing values and normality of the total score), internal consistency (Cronbach’s alpha), convergent, discriminant and known group differences validity (Spearman correlations, Wilcoxon Mann-Whitney and Kruskal-Wallis tests) were assessed. The distribution of HRQL by socio-demographic and functional descriptors was explored. Results The HRQL score ranged from 0 to 16 and showed an internal consistency Alpha of 0.74. Validity of the instrument was found to be acceptable. Men had higher HRQL than women. Marital status had a greater effect on HRQL for men than it did for women. The HRQL of those with good self-reported health was higher than those with fair/poor self-reported health. HRQL was not associated with dementia severity. Conclusions To our knowledge this is the first study to examine the distribution of dementia-specific HRQL in a population sample of the very old. We have mapped an existing conceptual framework of dementia specific HRQL onto an existing study and demonstrated the feasibility of this approach. Findings in this study suggest that whereas there is big emphasis in dementia severity, characteristics such as gender should be taken into account when assessing and implementing programmes to improve HRQL.

  8. Water-quality conditions, and constituent loads and yields in the Cambridge drinking-water source area, Massachusetts, water years 2005–07

    The source water area for the drinking-water supply of the city of Cambridge, Massachusetts, encompasses major transportation corridors, as well as large areas of light industrial, commercial, and residential land use. Because of ongoing development in the drinking-water source area, the Cambridge water supply has the potential to be affected by a wide variety of contaminants. The U.S. Geological Survey (USGS) has monitored surface-water quality in the Hobbs Brook and Stony Brook Basins, which compose the drinking-water source area, since 1997 (water year 1997) through continuous monitoring and discrete sample collection and, since 2004, through systematic collection of streamwater samples during base-flow and stormflow conditions at five primary sampling stations in the drinking-water source area. Four primary sampling stations are on small tributaries in the Hobbs Brook and Stony Brook Basins; the fifth primary sampling station is on the main stem of Stony Brook and drains about 93 percent of the Cambridge drinking-water source area. Water samples also were collected at six secondary sampling stations, including Fresh Pond Reservoir, the final storage reservoir for the raw water supply. Storm runoff and base-flow concentrations of calcium (Ca), chloride (Cl), sodium (Na), and sulfate (SO4) were estimated from continuous records of streamflow and specific conductance for six monitoring stations, which include the five primary sampling stations. These data were used to characterize current water-quality conditions, estimate loads and yields, and describe trends in Cl and Na in the tributaries and main-stem streams in the Hobbs Brook and Stony Brook Basins. These data also were used to describe how streamwater quality is affected by various watershed characteristics and provide information to guide future watershed management. Water samples were analyzed for physical properties and concentrations of Ca, Cl, Na, and SO4, total nitrogen (TN), total phosphorus (TP), caffeine, and a suite of 59 polar pesticides. Values of physical properties and constituent concentrations varied widely, particularly in samples from tributaries. Median concentrations of Ca, Cl, Na, and SO4 in samples collected in the Hobbs Brook Basin (39.8, 392, 207, and 21.7 milligrams per liter (mg/L), respectively) were higher than those for the Stony Brook Basin (17.8, 87.7, 49.7, and 14.7 mg/L, respectively). These differences in major ion concentrations are likely related to the low percentages of developed land and impervious area in the Stony Brook Basin. Concentrations of dissolved Cl and Na in samples, and those estimated from continuous records of specific conductance (particularly during base flow), often were greater than the U.S. Environmental Protection Agency (USEPA) secondary drinking-water guideline for Cl (250 mg/L), the chronic aquatic-life guideline for Cl (230 mg/L), and the Commonwealth of Massachusetts, Executive Office of Energy and Environmental Affairs drinking-water guideline for Na (20 mg/L). Mean annual flow-weighted concentrations of Ca, Cl, and Na were generally positively correlated with the area of roadway land use in the subbasins. Correlations between mean annual concentrations of Ca and SO4 in base flow and total roadway, total impervious, and commercial-industrial land uses were statistically significant. Concentrations of TN (range of 0.42 to 5.13 mg/L in all subbasins) and TP (range of 0.006 to 0.80 mg/L in all subbasins) in tributary samples did not differ substantially between the Hobbs Brook and Stony Brook Basins. Concentrations of TN and TP in samples collected during water years 2004–07 exceeded proposed reference concentrations of 0.57 and 0.024 mg/L, in 94 and 56 percent of the samples, respectively. Correlations between annual flow-weighted concentrations of TN and percentages of recreational land use and water-body area were statistically significant; however, no significant relation was found between TP and available land-use information. The volume of streamflow affected water-quality conditions at the primary sampling stations. Turbidity and concentrations of TP were positively correlated with streamflow. In contrast, concentrations of major ions were negatively correlated with streamflow, indicating that these constituents were diluted during stormflows. Concentrations of TN were not correlated with streamflow. Twenty-five pesticides and caffeine were detected in water samples collected in the drinking-water source area and in raw water collected from the Cambridge water-treatment facility intake at the Fresh Pond Reservoir. Imidacloprid, norflurazon, and siduron were the most frequently detected pesticides with the frequency of detections ranging from about 24 to 41 percent. Caffeine was detected in about 37 percent of water samples at concentrations ranging from 0.003 to 1.82 micrograms per liter (μg/L). Although some of the detected pesticides degrade rapidly, norflurazon and siduron are relatively stable and are able to immigrate though the serial reservoir system. Concentrations of 2,4-D, carbaryl, imazaquin, MCPA (2-methyl-4-chlorophenoxyacetic acid), metsulfuron-methyl, norflurazon, siduron, and caffeine were detected more frequently in stormflow samples than in base-flow samples. Concentrations of pesticides did not exceed USEPA drinking-water guidelines or other health standards and were several orders of magnitude less than the lethal exposure level established for several fish species common to the drinking-water source area. Imidacloprid, an insecticide, was the only pesticide with a concentration exceeding available long-term aquatic-life guidelines. Several pesticides correlated significantly with the amount of recreational, residential, and commercial area in the tributary subbasins. Mean annual base-flow concentrations of caffeine correlated significantly with parking-lot land use. For most tributaries, about 70 percent of the annual loads of Ca, Cl, Na, and SO4 were associated with base flow. Upward temporal trends in annual loads of Cl and Na were identified on the basis of data for water years 1998 to 2008 for the outlet of the Cambridge Reservoir in the Hobbs Brook Basin; however, similar trends were not identified for the main stem of Stony Brook downstream from the reservoir. The proportions of the TN load attributed to base flow and stormflow were similar in each tributary. In contrast, more than 83 percent of the TP loads in the tributaries and about 73 percent of the TP load in main stem of Stony Brook were associated with stormflow. Mean annual yields of Ca, Cl, Na, and SO4 in the Stony Brook Reservoir watershed, which represents most of the drinking-water source area, were 14, 85, 46, and 9 metric tons per square kilometer, respectively. Mean annual yields among the individual tributary subbasins varied extensively. Mean annual yields for the respective constituents increased with an increase in roadway and parking-lot area in the tributary subbasins. Mean annual yields of TN in the tributary subbasins ranged from about 740 to more than 1,200 kilograms per square kilometer and exceeded the yield for the main stem of Stony Brook at USGS station 01104460 upstream from the Stony Brook Reservoir. Mean annual yields estimated for the herbicides 2,4-D and imidacloprid ranged from 34 to 310 grams per square kilometer (g/km2) and 3 to 170 g/km2, respectively. Annual loads for 2,4-D were entirely associated with stormflow. The largest annual load for imidacloprid was estimated for the main stem of Stony Brook; however, the highest annual yield for this pesticide, as well as for benomyl, carbaryl, metalaxyl, and propiconazole, was estimated for a tributary to the Stony Brook Reservoir that drains largely residential and recreational areas. Mean annual yields for the herbicide siduron ranged from 6.9 to 35 g/km2 with most of the loads associated with stormflow. Mean annual yields for the insecticide diuron ranged from 2.1 to 4.4 g/km2. Annual yields of caffeine ranged from 11 to 410 g/km2.

    Background: Insulin sensitivity (Si) is improved by weight loss and exercise, but the effects of the replacement of saturated fatty acids (SFAs) with monounsaturated fatty acids (MUFAs) or carbohydrates of high glycemic index (HGI) or low glycemic index (LGI) are uncertain. Objective: We conducted a dietary intervention trial to study these effects in participants at risk of developing metabolic syndrome. Design: We conducted a 5-center, parallel design, randomized controlled trial [RISCK (Reading, Imperial, Surrey, Cambridge, and Kings)]. The primary and secondary outcomes were changes in Si (measured by using an intravenous glucose tolerance test) and cardiovascular risk factors. Measurements were made after 4 wk of a high-SFA and HGI (HS/HGI) diet and after a 24-wk intervention with HS/HGI (reference), high-MUFA and HGI (HM/HGI), HM and LGI (HM/LGI), low-fat and HGI (LF/HGI), and LF and LGI (LF/LGI) diets. Results: We analyzed data for 548 of 720 participants who were randomly assigned to treatment. The median Si was 2.7 × 10?4 mL · ?U?1 · min?1 (interquartile range: 2.0, 4.2 × 10?4 mL · ?U?1 · min?1), and unadjusted mean percentage changes (95% CIs) after 24 wk treatment (P = 0.13) were as follows: for the HS/HGI group, ?4% (?12.7%, 5.3%); for the HM/HGI group, 2.1% (?5.8%, 10.7%); for the HM/LGI group, ?3.5% (?10.6%, 4.3%); for the LF/HGI group, ?8.6% (?15.4%, ?1.1%); and for the LF/LGI group, 9.9% (2.4%, 18.0%). Total cholesterol (TC), LDL cholesterol, and apolipoprotein B concentrations decreased with SFA reduction. Decreases in TC and LDL-cholesterol concentrations were greater with LGI. Fat reduction lowered HDL cholesterol and apolipoprotein A1 and B concentrations. Conclusions: This study did not support the hypothesis that isoenergetic replacement of SFAs with MUFAs or carbohydrates has a favorable effect on Si. Lowering GI enhanced reductions in TC and LDL-cholesterol concentrations in subjects, with tentative evidence of improvements in Si in the LF-treatment group. This trial was registered at clinicaltrials.gov as ISRCTN29111298. PMID:20739418

    Objectives To investigate initial reliability of the Global Consultation Rating Scale (GCRS: an instrument to assess the effectiveness of communication across an entire doctor–patient consultation, based on the Calgary-Cambridge guide to the medical interview), in simulated patient consultations. Design Multiple ratings of simulated general practitioner (GP)–patient consultations by trained GP evaluators. Setting UK primary care. Participants 21 GPs and six trained GP evaluators. Outcome measures GCRS score. Methods 6 GP raters used GCRS to rate randomly assigned video recordings of GP consultations with simulated patients. Each of the 42 consultations was rated separately by four raters. We considered whether a fixed difference between scores had the same meaning at all levels of performance. We then examined the reliability of GCRS using mixed linear regression models. We augmented our regression model to also examine whether there were systematic biases between the scores given by different raters and to look for possible order effects. Results Assessing the communication quality of individual consultations, GCRS achieved a reliability of 0.73 (95% CI 0.44 to 0.79) for two raters, 0.80 (0.54 to 0.85) for three and 0.85 (0.61 to 0.88) for four. We found an average difference of 1.65 (on a 0–10 scale) in the scores given by the least and most generous raters: adjusting for this evaluator bias increased reliability to 0.78 (0.53 to 0.83) for two raters; 0.85 (0.63 to 0.88) for three and 0.88 (0.69 to 0.91) for four. There were considerable order effects, with later consultations (after 15–20 ratings) receiving, on average, scores more than one point higher on a 0–10 scale. Conclusions GCRS shows good reliability with three raters assessing each consultation. We are currently developing the scale further by assessing a large sample of real-world consultations.

    Quantum calculations at the DFT-D3/def2-TZVPD level of theory have been used to examine complexes between O2YBr (Y?N, P, and As) molecules and several Lewis bases, that is, NH3, H2O, and HF. The interactions of the lone pair of the ammonia, water, and hydrogen fluoride with the ?-hole and ?-hole of O2YBr molecules have been considered. In general, the complexes where the Lewis base lone pair interacts with the ?-hole are more favorable than those with ?-hole. The nature of the interactions has been characterized with the Bader theory of atoms in molecules (AIM). We have also studied the ability of trifluoronitromethane and nitromethane to interact with anions using their ?-hole along with an analysis the Cambridge Structural Database. We have found a large number of hits that provide strong experimental support for ability of the nitryl (-NO2) group to interact with anions and Lewis bases. In some X-ray structures, the ?-hole interaction is crucial in the crystal packing and has a strong influence in the solid state architecture of the complexes. Finally, due to the relevance in atmospheric chemistry, we have studied noncovalent ?/?-hole complexes of nitryl bromide with ozone. PMID:24679186

    In this book the use of inhomogeneous models in cosmology, both in modelling structure formation and interpreting cosmological observations, is discussed. The authors concentrate on exact solutions, and particularly the Lemaitre-Tolman (LT) and Szekeres models (the important topic of averaging is not discussed). The book serves to demonstrate that inhomogeneous metrics can generate realistic models of cosmic structure formation and nonlinear evolution and shows that general relativity has a lot more to offer to cosmology than just the standard spatially homogeneous FLRW model. I would recommend this book to people working in theoretical cosmology. In the introduction (and in the concluding chapter and throughout the book) a reasonable discussion of the potential problems with the standard FLRW cosmology is presented, and a list of examples illustrating the limitations of standard FLRW cosmology are discussed (including potential problems with perturbation methods). In particular, the authors argue that the assumptions of isotropy and spatial homogeneity (and consequently the Copernican principle) must be properly challenged and revisited. Indeed, it is possible for `good old general relativity' to be used to explain cosmological observations without introducing speculative elements. In part I of the book the necessary background is presented (readers need a background in general relativity theory at an advanced undergraduate or graduate level). There is a good (and easy to read) review of the exact spherically symmetric dust Lemaitre-Tolman model (LT) (often denoted the LTB model) and the Lemaitre and Szekeres models. Light propogation (i.e. null geodesics, for both central and off-center observers) in exact inhomogeneous (LT) models is reviewed. In part II a number of applications of exact inhomogeneous models are presented (taken mainly from the authors' own work). In chapter 4, the evolution of exact inhomogeneous models (primarily the LT model, but also the Szekeres model) is studied regarding structure formation. I thought that the authors describe the advantages and drawbacks of the idealized exact solutions used in the physical modelling in a reasonable manner (although more concise conclusions might have been useful). The authors also address the formation of a galaxy with a central black hole, the formation and evolution of rich galactic clusters and voids and other structures, and the effects of radiation in the models. The most interesting application is presented in chapter 5; namely, the effects of inhomogeneities on observations such as the luminosity distance relation and the explanation of the observed dimming of distant SN Ia (which is usually interpreted within the standard FLRW model in terms of the existence of dark energy). The main conclusion of this work is that data can be reproduced within the LT model (via inhomogeneities in general relativity, but without introducing dark energy). In particular, a number of exact LT solutions were surveyed, and a full discussion of various models in the literature (and a critique of the various assumptions) is presented. In the next chapter the possible resolution of the horizon problem without inflation, in terms of shell crossing in a LT model, is discussed. This is perhaps the most controversial chapter of the book. In the final chapter 7, the influence of inhomogeneous structures in the path of a light ray (for both center and off-center observers in a special Szekeres Swiss cheese model) on the observed temperature distribution of the CMB is discussed. This is a very important topic, but only a heuristic and qualitative study is presented here; more work on the multipole moments of higher order would be necessary for a more comprehensive analysis.

    van Genderen, A. M.

    Since about the early seventies no proper book on variable stars has been written. The probable reason is the explosive growth of the field of variable-star research during the 25 years since. It was not only the amount of observational data which grew so fast, but also the number of new types of variable stars and the knowledge of the causes of their variability. Variable stars also became of fastly growing importance for distance determinations, for the physics of stellar interiors and for stellar evolution. The two editors, together with seven other experts on variable stars have now found a perfect recipe to write a conveniently-sized book on variable stars. The time was ripe. They compiled a pictorial atlas of at least 200 typical light curves of tens of different kinds of variable stars. The book also gives a clear introduction to the historical background, the photometric systems, the nomenclature and the classifications. Each chapter provides a detailed account of each subclass and gives a concise description of the physical processes responsible for the variations. All specific variables discussed in the text can easily be located with the aid of object-name and subject indexes. The reference list contains about 600 entries, a guarantee that one can access a particular subject quickly and in debt. The quality of the figures and the tables is very good. Very useful is the inclusion of three lists, 'Journal abbreviations', 'Acronyms and abbreviations' and 'Addresses of interest', and of three tables concerning constellation names, Julian dates, and specialized newsletters on variable stars. This unique guide will be absolutely invaluable to students taking courses in variable-star research, as well as for professional and amateur astronomers.

    Extracting information from seismic data requires knowledge of seismic wave propagation and reflection. The commonly used method involves solving linearly for a reflectivity at every point within the Earth, but this book follows an alternative approach which invokes inverse scattering theory. By developing the theory of seismic imaging from basic principles, the authors relate the different models of seismic propagation, reflection and imaging - thus providing links to reflectivity-based imaging on the one hand and to nonlinear seismic inversion on the other. The comprehensive and physically complete linear imaging foundation developed presents new results at the leading edge of seismic processing for target location and identification. This book serves as a fundamental guide to seismic imaging principles and algorithms and their foundation in inverse scattering theory and is a valuable resource for working geoscientists, scientific programmers and theoretical physicists.

    A Lagrangian model of photochemistry and mixing is described (CiTTyCAT, stemming from the Cambridge Tropospheric Trajectory model of Chemistry And Transport), which is suitable for transport and chemistry studies throughout the troposphere. Over the last five years, the model has been developed in parallel at several different institutions and here those developments have been incorporated into one "community" model and documented for the first time. The key photochemical developments include a new scheme for biogenic volatile organic compounds and updated emissions schemes. The key physical development is to evolve composition following an ensemble of trajectories within neighbouring air-masses, including a simple scheme for mixing between them via an evolving "background profile", both within the boundary layer and free troposphere. The model runs along trajectories pre-calculated using winds and temperature from meteorological analyses. In addition, boundary layer height and precipitation rates, output from the analysis model, are interpolated to trajectory points and used as inputs to the mixing and wet deposition schemes. The model is most suitable in regimes when the effects of small-scale turbulent mixing are slow relative to advection by the resolved winds so that coherent air-masses form with distinct composition and strong gradients between them. Such air-masses can persist for many days while stretching, folding and thinning. Lagrangian models offer a useful framework for picking apart the processes of air-mass evolution over inter-continental distances, without being hindered by the numerical diffusion inherent to global Eulerian models. The model, including different box and trajectory modes, is described and some output for each of the modes is presented for evaluation. The model is available for download from a Subversion-controlled repository by contacting the corresponding authors.

    1990-01-01

    A comprehensive and intensively illustrated development history is presented for spaceflight, ranging over its basic concepts' speculative and fictional origins, the historical roots of rocket-related technologies, and the scientific accomplishments of earth orbit and interplanetary missions to date. Attention is given to propulsion systems, spaceflight launch centers, satellite systems, and solar system exploration by the U.S. and the Soviet Union. Current space-related activities encompass the meteorology, remote sensing, telecommunications and direct broadcasting, and navigation functions of unmanned satellites, as well as such manned spacecraft roles as medical and materials science research. The military uses of space, and increasingly important space industrialization concepts, are discussed as well.

  14. Are changes in glycaemic control associated with diabetes-specific quality of life and health status in screen-detected type 2 diabetes patients? Four-year follow up of the ADDITION-Cambridge cohort

    PubMed Central

    Kuznetsov, L; Long, G H; Griffin, S J; Simmons, R K

    2015-01-01

    Background Interventions that improve HbA1c levels do not necessarily improve health-related quality of life (QoL). This issue may be particularly relevant in asymptomatic diabetes patients detected earlier in the course of the disease. Methods HbA1c, diabetes-specific QoL (ADDQoL) and health status were measured in 510 screen-detected diabetes patients from the ADDITION-Cambridge trial at 1 and 5 years post diagnosis. Multivariable logistic/linear regression was used to quantify the longitudinal association between change in HbA1c from 1 to 5 years and ADDQoL and health status at 5 years, adjusting for age, sex, education and trial group; alcohol consumption, smoking, physical activity, plasma vitamin C, HbA1c, ADDQoL or health status at 1 year, and glucose-lowering medication at 5 years. Results From 1 to 5 years, median HbA1c interquartile range increased from 6.3% (5.9–6.8) to 6.8% (6.4–7.4); the median ADDQoL score and mean health status physical health summary score decreased from -0.4 (-1 to -0.08) to -0.5 (-1.08 to -0.09) (suggesting an adverse impact of diabetes on QoL) and by -0.79 (8.94) points, respectively. Increases in HbA1c were independently associated with reporting a negative impact of diabetes on QoL (OR = 1.38, 95% CI: 1.03 to 1.85) but not with the health status summary scores. Conclusions Increases in HbA1c from 1 to 5 years post-diagnosis were independently associated with increased odds of reporting a negative impact of diabetes on QoL. While our results suggest that efforts to reduce HbA1c do not adversely affect health-related QoL, large numbers of participants still report a negative impact of diabetes on their QoL 5 years post-diagnosis. © 2014 The Authors.

  15. Book review: Modern Plasma Physics, Vol. I: Physical Kinetics of Turbulent Plasmas, by Patrick H. Diamond, Sanae-I. Itoh and Kimitaka Itoh, Cambridge University Press, Cambridge (UK), 2010, IX, 417 p., ISBN 978-0-521-86920-1 (Hardback)

    NASA Astrophysics Data System (ADS)

    Somov, B. V.

    If you want to learn not only the most fundamental things about the physics of turbulent plasmas but also the current state of the problem including the most recent results in theoretical and experimental investigations - and certainly many physicists and astrophysicists do - this series of three excellent monographs is just for you. The first volume "Physical Kinetics of Turbulent Plasmas" develops the kinetic theory of turbulence through a focus on quasi-particle models and dynamics. It discusses the concepts and theoretical methods for describing weak and strong fluid and phase space turbulence in plasma systems far from equilibrium. The core material includes fluctuation theory, self-similar cascades and transport, mean field theory, resonance broadening and nonlinear wave-particle interaction, wave-wave interaction and wave turbulence, strong turbulence theory and renormalization. The book gives readers a deep understanding of the fields under consideration and builds a foundation for future applications to multi-scale processes of self-organization in tokamaks and other confined plasmas. In spite of a short pedagogical introduction, the book is addressed mainly to well prepared readers with a serious background in plasma physics, to researchers and advanced graduate students in nonlinear plasma physics, controlled fusions and related fields such as cosmic plasma physics

    NASA Astrophysics Data System (ADS)

    Crawford, Ian

    2004-12-01

    This book provides an astonishingly comprehensive review of its subject, from the fundamental physics of radiative transfer, through the design, calibration and operation of infrared spectrometers, to a summary of recent results. Along the way, it deals also with the spectra of diatomic and polyatomic molecules, and the structure and composition of planetary atmospheres. The treatment is authoritative-the authors have all been leading researchers in the field, and between them have something like 130 years experience in the study of planetary spectra using ground-based and space-borne instruments. While not shrinking from mathematical rigour, where this is required, the style is generally easy to follow, and should be accessible to postgraduate, and advanced undergraduate students, in relevant disciplines. Moreover, the treatment is so comprehensive that it is hard to imagine that even the most established planetary scientist would not learn something from it. The community can be grateful that the authors have chosen to distil their knowledge into a form suitable for passing on to their colleagues, and most importantly, the next generation of researchers.

  17. The Cambridge-Cambridge X-ray Serendipity Survey: I X-ray luminous galaxies

    NASA Technical Reports Server (NTRS)

    Boyle, B. J.; Mcmahon, R. G.; Wilkes, B. J.; Elvis, M.

    1994-01-01

    We report on the first results obtained from a new optical identification program of 123 faint X-ray sources with S(0.5-2 keV) greater than 2 x 10(exp -14) erg/s/sq cm serendipitously detected in ROSAT PSPC pointed observations. We have spectroscopically identified the optical counterparts to more than 100 sources in this survey. Although the majority of the sample (68 objects) are QSO's, we have also identified 12 narrow emission line galaxies which have extreme X-ray luminosities (10(exp 42) less than L(sub X) less than 10(exp 43.5) erg/s). Subsequent spectroscopy reveals them to be a mixture of star-burst galaxies and Seyfert 2 galaxies in approximately equal numbers. Combined with potentially similar objects identified in the Einstein Extended Medium Sensitivity Survey, these X-ray luminous galaxies exhibit a rate of cosmological evolution, L(sub X) varies as (1 + z)(exp 2.5 +/- 1.0), consistent with that derived for X-ray QSO's. This evolution, coupled with the steep slope determined for the faint end of the X-ray luminosity function (Phi(L(sub X)) varies as L(sub X)(exp -1.9)), implies that such objects could comprise 15-35% of the soft (1-2 keV) X-ray background.

    The three major objectives are: (1) to measure the extent to which the organization renewal techniques have been adopted by organizations in both the private and public sectors; (2) to determine the overall results of these applications; and (3) to test a number of specific hypotheses regarding situational determinants of the success of this approach. It appears that top management involvement is the single most crucial determinant of the success of organization renewal. Organization renewal has considerable potential for increasing the commitment of individuals, and can have a significant positive influence on the results of the organization.

  18. Ingestion of phosphorus-32 at Massachusetts Institute of Technology, Cambridge, Massachusetts, identified on August 19, 1995

    SciTech Connect

    1995-12-01

    On Monday, October 16, 1995, the Massachussetts Institue of Technology (MIT, the licensee) notified the US Nuclear Regulatory Commission (NRC) of an incident involving ingestion of phosphorus-32 by a researcher at the MIT Center for Cancer Research. The licensee informed the NRC that a researcher had reported the incident on August 19. The licensee initially estimated the intake as 500 microcuries (19 MBq) and the dose as 4000 millirem (40 mSv) to the individual. On October 12, the licensee informed the researcher that its final intake estimate was 579 microcuries (21 MBq), just under the 600 microcuries (22 MBq) which would represent an overexposure. On October 17, the NRC established an Incident Investigation Team to investigate the case. NRC also contracted with Lawrence Livermore National Laboratory and Oak Ridge Institute for Science and Education to do independent dose assessments of the urine sample data and the whole-body data. The Team concluded that the licensee`s final intake and dose estimates were in accordance with accepted scientific references and NRC guidance. However, recognizing the uncertainties involved in the use of models to simulate human characteristics, the Team determined the intake would be better characterized as likely falling within a range of 500 to 750 microcuries (19--28 NMq). An NRC medical consultant concluded that no symptoms or acute effects should be observed from an intake of this level.

  4. The sound of moving bodies. Ph.D. Thesis - Cambridge Univ.

    Brentner, Kenneth Steven

    1990-01-01

    The importance of the quadrupole source term in the Ffowcs, Williams, and Hawkings (FWH) equation was addressed. The quadrupole source contains fundamental components of the complete fluid mechanics problem, which are ignored only at the risk of error. The results made it clear that any application of the acoustic analogy should begin with all of the source terms in the FWH theory. The direct calculation of the acoustic field as part of the complete unsteady fluid mechanics problem using CFD is considered. It was shown that aeroelastic calculation can indeed be made with CFD codes. The results indicate that the acoustic field is the most susceptible component of the computation to numerical error. Therefore, the ability to measure the damping of acoustic waves is absolutely essential both to develop acoustic computations. Essential groundwork for a new approach to the problem of sound generation by moving bodies is presented. This new computational acoustic approach holds the promise of solving many problems hitherto pushed aside.

    Whitehouse, A M; Cooper, P J; Vize, C V; Hill, C; Vogel, L

    1992-01-01

    The aims of this study were to investigate the prevalence of anorexia nervosa, bulimia nervosa and partial syndromes in women general practice attenders to establish the relative proportions of 'conspicuous' and 'hidden' morbidity. A consecutive series of 540 women patients aged 16-35 years attending their family doctor were screened using a specially devised questionnaire, the weight and dietary practices survey. A total of 115 patients were selected for further assessment and of these 101 patients were interviewed using a standardized diagnostic interview for DSM III-R eating disorders. The prevalence of anorexia nervosa was 0.2% (one case), of bulimia nervosa 1.5% (eight cases) and of partial syndrome bulimia nervosa 5.4% (29 cases). Half of the cases of bulimia nervosa had not been identified by the general practitioner and two of these patients had been referred to specialists for treatment of secondary complications of the eating disorder. Hidden cases of bulimia nervosa or partial syndromes are relatively common in general practice. Certain key questions could be used by general practitioners in order to identify women with eating disorders. PMID:1493006

    Analysis of pathological data in the 10th year of follow-up of a multicentre trial of the management of operable breast cancer has confirmed the correlation of prognosis with tumour grade, tumour size and lymph-node status. For each factor examined there was no difference in survival between the 2 treatment groups ("watch policy" and radiotherapy) but patients in the WP group whose tumours were of Grade II or III or greater than 2 cm, or with lymph-node metastases, had a greater chance of local recurrence. Cellular reaction had no relationship with prognosis, except in patients with Grade III tumours. The clinical relevance and application of these results are discussed. PMID:7044401

    We present 74 and 330 MHz Very Large Array (VLA) cycling snapshot observations of ˜ 20 resolved radio galaxies and supernova remnants from the 3C catalog. Most of the objects range from a few tens to a few hundreds of Janskys integrated flux density, demonstrating the improved sensitivity and uv coverage of the 27-antenna VLA 74 MHz system compared to an initial 8-antenna system. They also demonstrate that simple, angle-invariant self-calibration and now commonly available radio frequency interference excision and wide-field imaging techniques are sufficient for making good images of these relatively bright, isolated objects. More advanced techniques, as are now being demonstrated with the VLA Low Frequency Sky Survey, are needed to push to the full field-of-view imaging required to study weaker sources. We present total intensity images at 74 and 330 MHz together with spectral index maps. After demonstrating that the gain stability of the 74 MHz VLA system is accurate to 5%, we combine our new measurements with those collected by Kühr and Laing & Peacock, and rederive the low-frequency spectra of all the sources in our sample.

    Introduction Globally, dementia is the most frequent form of degenerative condition in the older adult population and poses a major health burden with high socioeconomic costs. So far, attempts to find pharmacologic interventions that can change the onset or progression of dementia have been largely unsuccessful, prompting a shift to focus on interventions aimed at modifying risk factors that occur throughout the life course. Methods The Cognitive Function and Ageing Studies, funded by the Medical Research Council, UK, convened three multidisciplinary groups of experts, expert witnesses, and advocates to discuss the state of evidence on primary, secondary, and tertiary dementia prevention and recommend future direction for intervention studies. Results Using the United Kingdom Parliamentary Select Committees' approach to gathering evidence, the primary prevention working group focused their deliberation on risk factors strongly associated with dementia. The group highlighted the need for high-quality studies to assess the effects of behavioral intervention on the delay of cognitive decline and dementia onset. Discussion The working group recommended that the development of a future dementia prevention trial should use a multimodal, multifactor, multilevel, community and individually tailored approach.

    2002-01-01

    In silico biology, the computer aided analysis of biological systems, is a relatively young research area. It first has been coined in the late 1990's and emerged from Theoretical and Computational Biology. As in other fields before, biology experiences an increased use of systems mathematics and computer simulation. With the human genome sequence available, with an exponentially growing number of completely sequenced genomes from various model organisms and with expression and proteomic data at hand, the research paradigm is shifted towards systems analysis and simulation. Computer aided modeling of complex biomolecules and assemblies are already routinely performed. Nowadays, theoretical description and computer simulation of cellular components in larger intra- and inter-cellular networks is of growing importance. Together with classic biological and clinical experiments as well as data from functional genomics, in silico biology will take the leading role in the analysis of biological systems.

    Adults with Asperger Syndrome (AS) can recognise simple emotions and pass basic theory of mind tasks, but have difficulties recognising more complex emotions and mental states. This study describes a new battery of tasks, testing recognition of 20 complex emotions and mental states from faces and voices. The battery was given to males and females with AS and matched controls. Results showed the AS group performed worse than controls overall, on emotion recognition from faces and voices and on 12/20 specific emotions. Females recognised faces better than males regardless of diagnosis, and males with AS had more difficulties recognising emotions from faces than from voices. The implications of these results are discussed in relation to social functioning in AS. PMID:16477515

    Latinos who present for health services often suffer from a complex interaction of medical and mental health needs, requiring a multifaceted intervention. An essential element of this multilevel approach is cultural and linguistic sensitivity on the part of health providers. New, innovative models of health service organization are needed to address the unique needs of the Latino population. Some of the key characteristics these models need to focus on include interagency collaboration rather than competition for resources, interdisciplinary teams of primary-care providers that also involve other nonmedical professional members, centralized case coordination and decentralized service delivery, flexibility and adaptability to changing priorities, continuity of care for all patients, and mutual support among providers to minimize the effects of stress and burnout.

    An adaptive numeric predictor-corrector guidance is developed for atmospheric entry vehicles which utilize lift to achieve maximum footprint capability. Applicability of the guidance design to vehicles with a wide range of performance capabilities is desired so as to reduce the need for algorithm redesign with each new vehicle. Adaptability is desired to minimize mission-specific analysis and planning. The guidance algorithm motivation and design are presented. Performance is assessed for application of the algorithm to the NASA Entry Research Vehicle (ERV). The dispersions the guidance must be designed to handle are presented. The achievable operational footprint for expected worst-case dispersions is presented. The algorithm performs excellently for the expected dispersions and captures most of the achievable footprint.

    The traveler attended a workshop on Terrestrial Field Testing of Pesticides and presented a paper on Risk Assessment Models. The workshop addressed the role of field testing in assessment and discussed procedures for testing. Environmental assessment problems are similar for pesticides and other chemicals, but such problems are accentuated for pesticides because of their high toxicity and the fact that these substances are applied at rates that are intended to be bioactive. The major issue of contention was the relative roles of laboratory testing, filed testing, and monitoring the effects of pesticide use.

    E.D. Adrian, F.R.S. (1889-1975) was one of Britain's most distinguished neurophysiologists, who, during a long and productive lifetime, achieved most honours and distinctions available to a scientific man. These included the 1932 Nobel Prize for Physiology or Medicine, shared with Sir Charles Sherrington, F.R.S., the Order of Merit (1942), and Presidency of the Royal Society (1950-55). His interest in the nervous system started at the beginning of his undergraduate career, much influenced by his Director of Studies, Keith Lucas, F.R.S. (1879-1916). Lucas, a skilled and imaginative neurophysiologist, was particularly renowned for his technical ability to design and build new equipment. In turn, his pupil's work on recording and analysing the electrical impulses in nervous tissue was also facilitated by the development of appropriate, sensitive instrumentation. This paper will describe Adrian's first use of valve amplifiers to enlarge the extremely small electrical signals then obtainable in the physiological laboratory, a development that epitomized the beginning of the electronic revolution in life sciences' laboratories.

  12. The contribution of media analysis to the evaluation of environmental interventions: the commuting and health in Cambridge study

    PubMed Central

    2014-01-01

    Background Media content can increase awareness of, and shape interactions with, public health interventions. As part of a natural experimental evaluation of the travel, physical activity and health impacts of the Cambridgeshire Guided Busway, we analysed print and social media discourse and interview data to understand the nature of new transport infrastructure and how it was experienced. Methods Newspaper articles were systematically retrieved from the LexisNexis database and tweets were identified from an online archive. Interviews were conducted as part of the larger evaluation study with 38 adults. Inductive thematic analysis was performed and comparisons were drawn between datasets. Results The findings are discussed in relation to five themes. First, an understanding of the intervention context and how the intervention was experienced was developed through accounts of events occurring pre and post the busway’s opening. Second, the media captured the dynamic nature of the intervention. Third, the media constructed idealised portrayals of the anticipated busway which in some cases were contradicted by the impact of the busway on the existing context and people’s lived experiences. Fourth, differential media coverage of the intervention components suggested that a lesser value was placed on promoting active travel compared with public transport. Lastly, interview data provided support for the hypothesis that the media increased awareness of the busway and served as a frame of reference for constructing expectations and comparing experiences. Conclusions This analysis has contributed to the wider evaluation of the busway, helping to understand its nature and implementation and informing hypotheses about how the local population interact with the infrastructure by attending to the significance of representations in the media.

    2008-04-01

    William Band (1906-1993) has been widely remembered by his American colleagues and students as ``a fine physicist and teacher,'' who taught at Washington State University in Pullman between 1949 and 1971 and authored Introduction to Quantum Statistics (1954) and Introduction to Mathematical Physics (1959). Not many, however, knew much about Band's early career, which was very ``uncommon and eventful.'' Born in England, Band graduated from University of Liverpool in 1927 with an MsSc degree in physics. Instead of pursuing his Ph.D. at Cambridge, he chose to teach physics at Yenching University, a prestigious Christian university in Beijing, China. Arriving in 1929, Band established his career at Yenching, where he taught and researched the theory of relativity and quantum mechanics, pioneered the study on low-temperature superconductivity in China, founded the country's first graduate program in physics, and chaired the Physics Department for 10 years until he fled from Yenching upon hearing of the attack on Pearl Harbor. It took him two years to cross Japanese occupied areas under the escort of the Communist force; he left China in early 1945. This presentation will explore Band's motivation to work in China and his contributions to the Chinese physics research and education.

  16. Astronomers Take the Measure of Dark Matter in the universe

    NASA Astrophysics Data System (ADS)

    2001-09-01

    Using NASA's Chandra X-ray Observatory, astronomers have obtained their most accurate determination to date of the amount of dark matter in galaxy clusters, the most massive objects in the universe. The results provide an important step towards a precise measurement of the total matter density of the universe. These results were presented today by Steven W. Allen of the Institute of Astronomy in Cambridge, UK at a press conference at the `Two Years of Science with Chandra' symposium in Washington, DC. Allen and his colleagues Robert W. Schmidt and Andrew C. Fabian at the Institute of Astronomy observed a carefully chosen sample of five of the largest clusters of galaxies known, whose distances range from 1.5 to 4 billion light years. The team made temperature maps of the hot multimillion-degree gas that fills the clusters. "The temperature maps can be used to determine the mass needed to prevent the hot gas from escaping the clusters" explained Allen. "We found that the stars in the galaxies and hot gas together contribute only about 13 percent of the mass. The rest must be in the form of dark matter." The nature of the dark matter is not known, but most astronomers think that it is in the form of an as yet unknown type of elementary particle that contributes to gravity through its mass but otherwise interacts weakly with normal matter. These dark matter particles are often called WIMPs, an acronym for `weakly interacting massive particles'. Clusters of galaxies are vast concentrations of galaxies, hot gas and dark matter spanning millions of light years, held together by gravity. Because of their size, clusters of galaxies are thought to provide a fair sample of the proportion of dark matter in the universe as a whole. "The implication of our results is that we live in a low-density universe" said Allen. "The total mass-density is only about thirty percent of that needed to stop the universe from expanding forever." The result reinforces recent findings from measurements of the cosmic microwave background radiation, the large-scale distribution of galaxies, and the properties of distant supernovas. The Institute of Astronomy team minimized systematic errors in their work by placing independent constraints on the masses of the clusters using data from NASA's Hubble Space Telescope and the Canada-France-Hawaii Telescope atop Mauna Kea, HI. The new Chandra results also show how the average X-ray luminosity and temperature of the hot gas varies with the mass of a cluster. These findings should allow astronomers to use the data from large cluster catalogues, for which only X-ray luminosities are generally available, to get even more accurate measurements of the mean mass density of the universe, and to understand further the processes by which clusters form and grow. The Chandra observations were carried out using the Advanced CCD Imaging Spectrometer, which was built for NASA by the Massachusetts Institute of Technology, Cambridge, and Pennsylvania State University, University Park. NASA's Marshall Space Flight Center in Huntsville, AL, manages the Chandra program, and TRW, Inc., Redondo Beach, CA, is the prime contractor for the spacecraft. The Smithsonian's Chandra X-ray Center controls science and flight operations from Cambridge, MA.

  17. Facial expressions of emotion are not culturally universal.

    PubMed

    Jack, Rachael E; Garrod, Oliver G B; Yu, Hui; Caldara, Roberto; Schyns, Philippe G

    2012-05-01

    Since Darwin's seminal works, the universality of facial expressions of emotion has remained one of the longest standing debates in the biological and social sciences. Briefly stated, the universality hypothesis claims that all humans communicate six basic internal emotional states (happy, surprise, fear, disgust, anger, and sad) using the same facial movements by virtue of their biological and evolutionary origins [Susskind JM, et al. (2008) Nat Neurosci 11:843-850]. Here, we refute this assumed universality. Using a unique computer graphics platform that combines generative grammars [Chomsky N (1965) MIT Press, Cambridge, MA] with visual perception, we accessed the mind's eye of 30 Western and Eastern culture individuals and reconstructed their mental representations of the six basic facial expressions of emotion. Cross-cultural comparisons of the mental representations challenge universality on two separate counts. First, whereas Westerners represent each of the six basic emotions with a distinct set of facial movements common to the group, Easterners do not. Second, Easterners represent emotional intensity with distinctive dynamic eye activity. By refuting the long-standing universality hypothesis, our data highlight the powerful influence of culture on shaping basic behaviors once considered biologically hardwired. Consequently, our data open a unique nature-nurture debate across broad fields from evolutionary psychology and social neuroscience to social networking via digital avatars. PMID:22509011

  18. On the universal stellar law

    NASA Astrophysics Data System (ADS)

    Krot, Alexander

    In this work, we consider a statistical theory of gravitating spheroidal bodies to derive and develop the universal stellar law for extrasolar systems. Previously, the statistical theory for a cosmogonic body forming (so-called spheroidal body)has been proposed [1-3]. This theory starts from the conception for forming a spheroidal body inside a gas-dust protoplanetary nebula; it permits us to derive the form of distribution functions, mass density, gravitational potentials and strengths both for immovable and rotating spheroidal bodies as well as to find the distribution function of specific angular momentum[1-3]. If we start from the conception for forming a spheroidal body as a protostar (in particular, proto-Sun) inside a prestellar (presolar) nebula then the derived distribution functions of particle (as well as the mass density of an immovable spheroidal body) characterizes the first stage of evolution: from a prestellar molecular cloud (the presolar nebula) to the forming core of protostar (the proto-Sun) together with its shell as a stellar nebula (the solar nebula). This work derives the equation of state of an ideal stellar substance based on conception of gravitating spheroidal body. Using this equation, we obtain the universal stellar law (USL) for the planetary systems connecting temperature, size and mass of each of stars. This work also considers the Solar corona in the connection with USL. Then it is accounting under calculation of the ratio of temperature of the Solar corona to effective temperature of the Sun’ surfaceand modification of USL. To test justice of the modified USLfor different types of stars, the temperature of stellar corona is estimated. The prediction of parameters of stars is carrying out by means of the modified USL,as well as the Hertzsprung-Russell’s dependence [5-7]is derivedby means of USL directly. This paper also shows that knowledge of some characteristics for multi-planet extrasolar systems refines own parameters of stars. In this connection, comparison with estimations of temperatures using of the regression dependences for multi-planet extrasolar systems [8] testifies the obtained results entirely. References 1.

    With the ever-increasing instances of resistance to frontline TB drugs there is the need to develop novel strategies to fight the worldwide TB epidemic. Boosting the effect of the existing second-line antibiotic ethionamide by inhibiting the mycobacterial transcriptional repressor protein EthR is an attractive therapeutic strategy. Herein we report the use of a fragment based drug discovery approach for the structure-guided systematic merging of two fragment molecules, each binding twice to the hydrophobic cavity of EthR from M. tuberculosis. These together fill the entire binding pocket of EthR. We elaborated these fragment hits and developed small molecule inhibitors which have a 100-fold improvement of potency in vitro over the initial fragments. PMID:26806381

    Aims Establishing a balance between the benefits and harms of treatment is important among individuals with screen-detected diabetes, for whom the burden of treatment might be higher than the burden of the disease. We described the association between cardio-protective medication and health-related quality of life (HRQoL) among individuals with screen-detected diabetes. Methods 867 participants with screen-detected diabetes underwent clinical measurements at diagnosis, one and five years. General HRQoL (EQ5D) was measured at baseline, one- and five-years, and diabetes-specific HRQoL (ADDQoL-AWI) and health status (SF-36) at one and five years. Multivariable linear regression was used to quantify the association between change in HRQoL and change in cardio-protective medication. Results The median (IQR) number of prescribed cardio-protective agents was 2 (1 to 3) at diagnosis, 3 (2 to 4) at one year and 4 (3 to 5) at five years. Change in cardio-protective medication was not associated with change in HRQoL from diagnosis to one year. From one year to five years, change in cardio-protective agents was not associated with change in the SF-36 mental health score. One additional agent was associated with an increase in the SF-36 physical health score (2.1; 95%CI 0.4, 3.8) and an increase in the EQ-5D (0.05; 95%CI 0.02, 0.08). Conversely, one additional agent was associated with a decrease in the ADDQoL-AWI (?0.32; 95%CI ?0.51, ?0.13), compared to no change. Conclusions We found little evidence that increases in the number of cardio-protective medications impacted negatively on HRQoL among individuals with screen-detected diabetes over five years.

    A potent insecticidal toxin, β/δ-PrIT1, molecular mass of 5598.86 [M+H](+), was characterized from Phoneutria reidyi spider venom. Its partial amino acid sequence showed high similarity with insecticidal spider toxins from the genus Phoneutria. β/δ-PrIT1 was very toxic (LD50 = 4 nmol/g) to flies (Musca domestica), but not to mice (Mus musculus). Kinetic studies showed that (125)I-β/δ-PrIT1 binds to two distinct sites in insect sodium channels, with close affinity (Kd1 = 34.7 pM and Kd2 = 35.1 pM). Its association is rather fast (t1/2(1) = 1.4 min, t1/2(2) = 8.5 min) and its dissociation is a slower process (t1/2(1) = 5.4 min, t1/2(2) = 32.8 min). On rat brain synaptosomes β/δ-PrIT1 partially competed (∼30%) with the beta-toxin (125)I-CssIV, but did not compete with the alpha-toxin of reference (125)I-AaII, nor with the beta-toxin (125)I-TsVII. On cockroach nerve cord synaptosomes, β/δ-PrIT1 did not compete with the anti-insect toxin (125)I-LqqIT1, but it competed (IC50 = 80 pM) with the "alpha-like" toxin (125)I-BomIV. In cockroach neurons, β/δ-PrIT1 inhibited the inactivation of Nav-channels and it shifted the sodium channel activation to hyperpolarizing potentials. These results indicate two different binding sites for β/δ-PrIT1, leading to two different pharmacological responses. β/δ-PrIT1 is one of the most toxic spider toxins to insects without apparent toxicity to mammals, and provide new model for the development of insecticides.

  20. Dwarf Galaxy Gives universe A Breath of Fresh Oxygen

    NASA Astrophysics Data System (ADS)

    2002-07-01

    Astronomers have discovered that a nearby dwarf galaxy is spewing oxygen and other "heavy" elements into intergalactic space. This observation from NASA's Chandra X-ray Observatory supports the idea that dwarf galaxies may be responsible for most of the heavy elements between the galaxies. Despite comprising only a very small fraction of the mass of the universe, so-called heavy elements - everything other than hydrogen and helium -- are essential for the formation of planets and can greatly influence astronomical phenomena, including the rate at which galaxies form. A team led by Crystal Martin of the University of California, Santa Barbara, observed the dwarf galaxy NGC 1569 using Chandra. As reported in an article to be published in The Astrophysical Journal, they found that huge quantities of oxygen and other heavy elements are escaping from the galaxy in bubbles of multimillion-degree gases that are thousands of light years in diameter "Dwarf galaxies are much smaller than ordinary galaxies like our Milky Way and much more common," said Martin. "Because of their small mass, they have relatively low gravity and matter can escape more easily from dwarfs than normal galaxies. This makes them very important in understanding how the universe was seeded with various elements." Scientists have speculated that heavy elements escaping from dwarf galaxies in the early universe could play a dominant role in enriching the intergalactic gas from which other galaxies form. Enriched gas cools more quickly, so the rate and manner of formation of new galaxies in the early universe would have been strongly affected by this process. NGC 1569 X-ray/Optical Composite NGC 1569 Composite Optical/X-ray image "With Chandra it was possible to test these ideas," said Henry Kobulnicky of the University of Wisconsin, Madison, a member of the research team. "We could trace the distribution of oxygen and other elements in the galaxy and determine how much of this matter is escaping from the galaxy." NGC 1569 is a good case study because it is only about 7 million light years from Earth, and for the last 10 million to 20 million years it has been undergoing a burst of star formation and supernova explosions, perhaps triggered by a collision with a massive gas cloud. The supernovas eject oxygen and other heavy elements at high velocity into the gas in the galaxy, heating it to millions of degrees. Hot gas boils off the gaseous disk of the galaxy and expands outward at speeds of hundreds of thousands of miles per hour. The team found large hot bubbles extending above and below a disk of gas along the equator of the galaxy. The measured concentration of oxygen, neon, magnesium, and silicon showed that the elements from thousands of supernovas are evaporating out of the galaxy, carrying much of the surrounding gas with them. The astronomers estimate the bubbles are carrying away an amount of oxygen equivalent to that found in about 3 million suns. In addition to Martin and Kobulnicky, Timothy Heckman of John Hopkins University in Baltimore, was part of the team that observed NGC 1569 for 27.4 hours using the Advanced CCD Imaging Spectrometer (ACIS) on April 11, 2001.

    2005-07-01

    The cosmos is an awfully big place and there is no better guide to its vast expanse and fascinating nooks and crannies than John Barrow. A professor of mathematical sciences at Cambridge University, Barrow embodies that rare combination of highly polished writer and expert scientist. His deft touch brings together the disparate threads of human knowledge and weaves them into a tapestry as rich and interesting for the expert as it is for the layperson. The Artful Universe Expanded is an updated edition of this popular book first published in 1995. It explores the deeply profound manner in which natural law and the nature of the cosmos have moulded and shaped us, our cultures and the very form of our arts and music—a new type of `cosmic' anthropology. The main themes Barrow chooses for revealing this new anthropology are the subjects of evolution, the size of things, the heavens and the nature of music. The book is a large, eclectic repository of knowledge often unavailable to the layperson,\\endcolumn hidden in esoteric libraries around the world. It rivals The Da Vinci Code for entertainment value and insights, but this time it is Nature’s code that is revealed. It is rare indeed to find common threads drawn through topics as diverse as The Beetles, Bach and Beethoven or between Jackson Pollock, the Aztecs, Kant, Picasso, Byzantine mosaics, uranium-235 and the helix nebula. Barrow unerringly binds them together, presenting them in a stimulating, conversational style that belies the amount of time that must have gone into researching this book. Dip into it at random, or read it from cover to cover, but do read it. The Artful Universe Expanded is an entertaining antidote to the oft-lamented pressures to know more and more about less and less and the apparently inexorable march of specialization. On reading this book one can, for a short time at least, hold in one’s mind a vision that unifies science, art and culture and glimpse a universal tapestry of great beauty.

  3. Dark Energy Found Stifling Growth in Universe

    NASA Astrophysics Data System (ADS)

    2008-12-01

    WASHINGTON -- For the first time, astronomers have clearly seen the effects of "dark energy" on the most massive collapsed objects in the universe using NASA's Chandra X-ray Observatory. By tracking how dark energy has stifled the growth of galaxy clusters and combining this with previous studies, scientists have obtained the best clues yet about what dark energy is and what the destiny of the universe could be. This work, which took years to complete, is separate from other methods of dark energy research such as supernovas. These new X-ray results provide a crucial independent test of dark energy, long sought by scientists, which depends on how gravity competes with accelerated expansion in the growth of cosmic structures. Techniques based on distance measurements, such as supernova work, do not have this special sensitivity. Scientists think dark energy is a form of repulsive gravity that now dominates the universe, although they have no clear picture of what it actually is. Understanding the nature of dark energy is one of the biggest problems in science. Possibilities include the cosmological constant, which is equivalent to the energy of empty space. Other possibilities include a modification in general relativity on the largest scales, or a more general physical field. People Who Read This Also Read... Chandra Data Reveal Rapidly Whirling Black Holes Ghostly Glow Reveals a Hidden Class of Long-Wavelength Radio Emitters Powerful Nearby Supernova Caught By Web Cassiopeia A Comes Alive Across Time and Space To help decide between these options, a new way of looking at dark energy is required. It is accomplished by observing how cosmic acceleration affects the growth of galaxy clusters over time. "This result could be described as 'arrested development of the universe'," said Alexey Vikhlinin of the Smithsonian Astrophysical Observatory in Cambridge, Mass., who led the research. "Whatever is forcing the expansion of the universe to speed up is also forcing its development to slow down." Vikhlinin and his colleagues used Chandra to observe the hot gas in dozens of galaxy clusters, which are the largest collapsed objects in the universe. Some of these clusters are relatively close and others are more than halfway across the universe. The results show the increase in mass of the galaxy clusters over time aligns with a universe dominated by dark energy. It is more difficult for objects like galaxy clusters to grow when space is stretched, as caused by dark energy. Vikhlinin and his team see this effect clearly in their data. The results are remarkably consistent with those from the distance measurements, revealing general relativity applies, as expected, on large scales. "For years, scientists have wanted to start testing how gravity works on large scales and now, we finally have," said William Forman, a co-author of the study from the Smithsonian Astrophysical Observatory. "This is a test that general relativity could have failed." When combined with other clues -- supernovas, the study of the cosmic microwave background, and the distribution of galaxies -- this new X-ray result gives scientists the best insight to date on the properties of dark energy. The study strengthens the evidence that dark energy is the cosmological constant. Although it is the leading candidate to explain dark energy, theoretical work suggests it should be about 10 raised to the power of 120 times larger than observed. Therefore, alternatives to general relativity, such as theories involving hidden dimensions, are being explored. "Putting all of this data together gives us the strongest evidence yet that dark energy is the cosmological constant, or in other words, that 'nothing weighs something'," said Vikhlinin. "A lot more testing is needed, but so far Einstein's theory is looking as good as ever." These results have consequences for predicting the ultimate fate of the universe. If dark energy is explained by the cosmological constant, the expansion of the universe will continue to accelerate, and the Milky Way and its neighbor galaxy, Andromeda, never will merge with the Virgo cluster. In that case, about a hundred billion years from now, all other galaxies ultimately would disappear from the Milky Way's view and, eventually, the local superclusters of galaxies also would disintegrate. The work by Vikhlinin and his colleagues will be published in two separate papers in the Feb. 10 issue of The Astrophysical Journal. NASA's Marshall Space Flight Center in Huntsville, Ala., manages the Chandra program for NASA's Science Mission Directorate in Washington.

The context of student learning in an undergraduate midwifery programme is analysed using human activity theory [Engeström, Y., 2001. Expansive learning at work: toward an activity theoretical reconceptualization. Journal of Education and Work, 14, 133-156]. The advantages of this approach to student learning as opposed to situated learning theory and the concept of legitimate peripheral participation [Lave, J., Wenger, E., 1991. Situated Learning: Legitimate Peripheral Participation. Cambridge University Press, New York] are discussed. An activity system changes as a result of contradictions and tensions between what it purports to produce and the views of stakeholders (multi-voicedness) as well as its historical context (Historicity of activity). A focus group with students highlights their expressed need for more simulated practice experience. The views of midwifery lecturers are sought as an alternative voice on this tension in the current programme. Qualitative differences in types of simulated experience are explored and concerns about resources are raised in the analysis. Discussion considers the value of well planned simulations in encouraging the expression of tacit understanding through a group deliberative learning process [Eraut, M., 2000. Non-formal learning, implicit learning and tacit knowledge in professional work. Journal of Educational Psychology, 70, 113-136]. PMID:17689430

  11. BOOK REVIEW: Universe or Multiverse?

    NASA Astrophysics Data System (ADS)

    Trimble, Virginia

    2008-11-01

    More than 2000 years ago, Epicurus taught that there are an infinite number of other worlds, both like and unlike ours, and Aristotle taught that there are none. Neither hypothesis can currently be falsified, and this issue of potential for falsification (that is testability) goes to the heart of many of the chapters in Carr's book. All but one of the 27 chapters, provided by 27 pundits (almost but not quite a one-to-one mapping) are written versions of talks given at one of three meetings, held between 2001 and 2005 at Stanford and Cambridge Universities and partly sponsored by the Templeton Foundation. Every reader will surely find some chapters interesting and informative, some provocative, and some rather vacuous. These will not be the same chapters for all readers. Two 'conflict of interest' statements: first, I spoke at one of these meetings, but was not one of those asked to provide a chapter. And, second, the first time I suggested in a lecture for scientists that 'many universes, either in temporal succession or embedded in higher dimensional space' was a possible explanation of the habitability of ours was fall 1974, shortly after Brandon Carter's first paper on anthropic principles and explanations, but before Bernard Carr and Martin Rees's 1979 Nature paper, which presented all the anthropic arguments then known and divided them into numbers that required no additional physics beyond the four standard forces (like the number of particles in a star) and those that seemed essential for life but not calculable (like the ratio of the electromagnetic to nuclear force constant). My other three possibilities were 'G.d has been very careful' (now called intelligent design), additional physics to be learned, and shear complexity. The core multiverse concept is that our universe (the 4-dimensional spacetime with which we are or could be connected and all its contents) is one of many, perhaps infinitely many, probably with different values of the constants of nature and other physical differences, which cannot communicate with ours even in principle. Such ensembles are predicted by some versions of inflation, string and M-theory. The anthropic principle is the idea that our universe has (or even must have) the structure, physics, chemistry and all required for me to be writing this and you to be reading it (editors are optional). Both concepts have firm supporters and firm opponents among the 26 male and one female authors. The woman, M-theorist Renata Kallosh, is for, and provides hints of how one might calculate, at least, the likelihood of our universe within an ensemble (a sort of testability). Her chapter is fairly heavy going in isolation, and readers who don't normally think about antisymmetric tensor gauge fields might want to start with John Donaghue, who explains what a particle physicist means by 'naturalness' and suggests that the known spectrum of quark and lepton masses might be a signature of multiverse origins. Given the Templeton sponsorship, you might reasonably want to know the extent to which 'progress in spirituality' has conditioned the topics covered. The answer is 'somewhat', in that authors range from the avowedly atheist (Stephen Hawking) to evangelical Christian quantum cosmologist Don Page, with stop-overs among the Jesuits (William Stoeger), philosophers of religion (Robin Collins), and the (I think) teleologists Paul Davies and John Barrow. There is also among the authors strong divergence of opinion on whether Hugh Everett's version of many worlds is (just) a quantum multiverse (Tegmark), almost certainly correct and meaningful (Page), or almost certainly wrong or meaningless (Carter). And two chapters, by Smolin and Weinberg, suggest that even the classic fine-tuning required for carbon to be formed from three helium nuclei may not be anthropically essential for a habitable universe. The last word belongs to Steven Weinberg. On previous occasions, Martin Rees has said that he has enough confidence in the multiverse to bet his dog's life on it, while Andrei Linde said he would bet his own life. Weinberg concludes his contribution by saying that he has just enough confidence in the multiverse to bet the lives of both Andrei Linde and Martin Rees's dog.

    Following Aoki’s statistical mechanics methodology [Masanao Aoki, New Approaches to Macroeconomic Modeling, Cambridge University Press, 1996; Masanao Aoki, Modeling Aggregate Behaviour and Fluctuations in Economics, Cambridge University Press, 2002; Masanao Aoki, and Hiroshi Yoshikawa, Reconstructing Macroeconomics, Cambridge University Press, 2006], we provide some insights into the well-known works of [Bruce Greenwald, Joseph Stiglitz, Macroeconomic models with equity and credit rationing, in: R. Hubbard (Ed.), Information, Capital Markets and Investment, Chicago University Press, Chicago, 1990; Bruce Greenwald, Joseph Stiglitz, Financial markets imperfections and business cycles, Quarterly journal of Economics (1993)]. Specifically, we reach analytically a closed form solution of their models overcoming the aggregation problem. The key idea is to represent the economy as an evolving complex system, composed by heterogeneous interacting agents, that can be partitioned into a space of macroscopic states. This meso level of aggregation permits to adopt mean-field interaction modeling and master equation techniques.

  7. Chandra Sees Shape of Universe During Formative, Adolescent Years

    NASA Astrophysics Data System (ADS)

    2003-03-01

    Scientists using NASA's Chandra X-ray Observatory have taken a snapshot of the adolescent universe from about five billion years ago when the familiar web-like structure of galaxy chains and voids first emerged. The observation reveals distant and massive galaxies dotting the sky, clustered together under the gravitational attraction of deep, unseen pockets of dark matter. This provides important clues of how the universe matured from its chaotic beginnings to its elegant structure we see today. These results are presented today in a press conference at the meeting of the High Energy Astrophysics Division of the American Astronomical Society at Mt. Tremblant, Quebec. "Piece by piece, we are assembling a photo album of the universe through the ages," said Yuxuan Yang, a doctorate candidate at the University of Maryland, College Park, who conducted the analysis. "Last month we saw a picture of the infant universe taken with the Wilkinson Microwave Anisotropy Probe. Now we can add a snapshot of its adolescence." The Chandra observation traced a patch of sky known as the Lockman Hole in the constellation Ursa Major (containing the Big Dipper). Chandra saw a rich density of active galaxies, seven times denser than what has been detected in previous optical and radio surveys at similar distances. This provides the clearest picture yet at the large-scale structure of the universe at such distances (and age), according to Dr. Richard Mushotzky of NASA Goddard Space Flight Center in Greenbelt, Md., who led the observation. Lockman Hole JPEG, TIFF, PS An image that has been "blurred" to allow better view of the structures outlined by the X-ray sources. The color represents the spectra of the AGN. The red color indicates the sources on average radiates at longer wavelength while green and blue colors indicates the sources radiates at shorter wavelength. The Green and blue regions appear to form a wall, or shows more lumpiness than the "red" sources. If one could capture the universe in a box, scientists say that the large scale structure -- that is, galaxies, galaxy clusters and voids of seemingly empty space -- takes the appearance of a web. Galaxies and intergalactic gas are strung like pearls on unseen filaments of dark matter, which comprises over 85 percent of all matter. Galaxies are attracted to dark matter's gravitational potential. Dark matter does not shine, like ordinary matter made of atoms, and may very well be intrinsically different. Chandra's observation of distant galaxies in the Lockman Hole, spread out over several billion light years from Earth, essentially maps the distribution of dark matter. This provides clues to how the universe grew. "We are seeing the universe during its formative years," said Mushotzky. "This is billions of years after galaxies were born, during a period when the universe began to take on the trappings of an adult." The galaxies that the team saw with Chandra were either dim or altogether undetectable with optical and radio telescopes. This may be because they are enshrouded in dust and gas, which blocks radio waves and optical light. X-rays, a higher-energy form of light, can penetrate this shroud. "Chandra is the only X-ray telescope with a spatial resolution comparable to the optical telescopes," according to Dr. Amy Barger of University of Wisconsin at Madison, who led the optical follow-up with the 10-meter Keck telescope on Mauna Kea, Hawaii. "This is critical to unambiguously identify the optical counterparts of the X-ray sources and measuring distances, or redshifts. This allows scientists to create a three-dimensional image of the large-scale structure." The additive effect of future deep and long Chandra surveys over the next few years will provide an even sharper picture of the young universe. Other scientists who participated in this observation include Drs. Len Cowie and Dave Sanders of the University of Hawaii, and Ph.D. student Aaron Steffen of the University of Wisconsin at Madison. NASA's Marshall Space Flight Center in Huntsville, Ala., manages the Chandra program, and TRW, Inc., Redondo Beach, Calif., is the prime contractor for the spacecraft.

  8. A natural history of mathematics: George Peacock and the making of English algebra.

    PubMed

    Lambert, Kevin

    2013-06-01

    In a series of papers read to the Cambridge Philosophical Society through the 1820s, the Cambridge mathematician George Peacock laid the foundation for a natural history of arithmetic that would tell a story of human progress from counting to modern arithmetic. The trajectory of that history, Peacock argued, established algebraic analysis as a form of universal reasoning that used empirically warranted operations of mind to think with symbols on paper. The science of counting would suggest arithmetic, arithmetic would suggest arithmetical algebra, and, finally, arithmetical algebra would suggest symbolic algebra. This philosophy of suggestion provided the foundation for Peacock's "principle of equivalent forms," which justified the practice of nineteenth-century English symbolic algebra. Peacock's philosophy of suggestion owed a considerable debt to the early Cambridge Philosophical Society culture of natural history. The aim of this essay is to show how that culture of natural history was constitutively significant to the practice of nineteenth-century English algebra. PMID:23961689

  9. How the Weak Variance of Momentum Can Turn Out to be Negative

    NASA Astrophysics Data System (ADS)

    Feyereisen, M. R.

    2015-05-01

    Weak values are average quantities, therefore investigating their associated variance is crucial in understanding their place in quantum mechanics. We develop the concept of a position-postselected weak variance of momentum as cohesively as possible, building primarily on material from Moyal (Mathematical Proceedings of the Cambridge Philosophical Society, Cambridge University Press, Cambridge, 1949) and Sonego (Found Phys 21(10):1135, 1991) . The weak variance is defined in terms of the Wigner function, using a standard construction from probability theory. We show this corresponds to a measurable quantity, which is not itself a weak value. It also leads naturally to a connection between the imaginary part of the weak value of momentum and the quantum potential. We study how the negativity of the Wigner function causes negative weak variances, and the implications this has on a class of `subquantum' theories. We also discuss the role of weak variances in studying determinism, deriving the classical limit from a variational principle.

    2012-03-01

    The origin and development of Punnett's Square for the enumeration and display of genotypes arising in a cross in Mendelian genetics is described. Due to R. C. Punnett, the idea evolved through the work of the 'Cambridge geneticists', including Punnett's colleagues William Bateson, E. R. Saunders and R. H. Lock, soon after the rediscovery of Mendel's paper in 1900. These geneticists were thoroughly familiar with Mendel's paper, which itself contained a similar square diagram. A previously-unpublished three-factor diagram by Sir Francis Galton existing in the Bateson correspondence in Cambridge University Library is then described. Finally the connection between Punnett's Square and Venn Diagrams is emphasized, and it is pointed out that Punnett, Lock and John Venn overlapped as Fellows of Gonville and Caius College, Cambridge. Copious illustrations are given. PMID:22326091

    NASA Astrophysics Data System (ADS)

    El Abed, Mohamed

    2016-01-01

    The purpose of hot wire anemometry is to measure the speed of an air stream. The classical method is based on the measure of the value of a temperature dependant resistor inserted in a Wheatstone bridge (Lomas 1986 Fundamentals of Hot Wire Anemometry (Cambridge: Cambridge University Press)). In this paper we exhibit the physics behind this method and show that by using a wire whose resistance does not vary on the field of temperature explored (from 20 °C to 200 °C), it is however possible to make accurate measurements. Finally, limitations of the method are discussed.

  14. Most Powerful Eruption in the Universe Discovered

    NASA Astrophysics Data System (ADS)

    2005-01-01

    Astronomers have found the most powerful eruption seen in the Universe using NASA's Chandra X-ray Observatory. A supermassive black hole generated this eruption by growing at a remarkable rate. This discovery shows the enormous appetite of large black holes, and the profound impact they have on their surroundings. The huge eruption is seen in a Chandra image of the hot, X-ray emitting gas of a galaxy cluster called MS 0735.6+7421. Two vast cavities extend away from the supermassive black hole in the cluster's central galaxy. The eruption - which has lasted for 100 million years and is still going - has generated the energy equivalent to hundreds of millions of gamma-ray bursts. Animation of Eruption from Supermassive Black Hole Animation of Eruption from Supermassive Black Hole This event was caused by gravitational energy release as enormous amounts of matter fell toward a black hole. Most of the matter was swallowed, but some of it was violently ejected before being captured by the black hole. "I was stunned to find that a mass of about 300 million Suns was swallowed," said Brian McNamara of Ohio University in Athens, lead author of the study that appears in the January 6, 2005 issue of Nature. "This is almost as massive as the supermassive black hole that swallowed it." Astronomers are not sure where such large amounts of matter came from. One theory is that gas from the host galaxy catastrophically cooled and was then swallowed by the black hole. Illustration of MS 0735.6+742 Illustration of MS 0735.6+742 The energy released shows that the black hole in MS 0735 has grown very dramatically during this eruption. Previous studies suggest that other large black holes have grown very little in the recent past, and that only smaller black holes are still growing quickly. "This new result is as surprising as it is exciting", said co-author Paul Nulsen of the Harvard-Smithsonian Center of Astrophysics. "This black hole is feasting when it should be fasting." Radio emission within the cavities shows that jets from the black hole erupted to create the cavities. Gas is being pushed away from the black hole at supersonic speeds over a distance of about a million light years. The mass of the displaced gas equals about a trillion Suns, more than the mass of all the stars in the Milky Way. LA Radio & Chandra X-ray Composite of MS 0735.6+7421 VLA Radio & Chandra X-ray Composite of MS 0735.6+7421 The rapid growth of supermassive black holes is usually detected by observing very bright radiation from the centers of galaxies in the optical and X-ray wavebands, or luminous radio jets. In MS 0735 no bright central radiation is found and the radio jets are faint. Therefore, the true nature of MS 0735 is only revealed through X-ray observations of the hot cluster gas. "Until now we had no idea that this black hole was gorging itself", said co-author Michael Wise of the Massachusetts Institute of Technology. "The discovery of this eruption shows that X-ray telescopes are necessary to understand some of the most violent events in the Universe." The astronomers estimated how much energy was needed to create the cavities by calculating the density, temperature and pressure of the hot gas. By making a standard assumption, that 10% of the gravitational energy goes into launching the jets, they estimated how much material the black hole swallowed. Size Comparison of MS 0735.6+7421 & Perseus Cluster Size Comparison of MS 0735.6+7421 & Perseus Cluster Besides generating the cavities, some of the energy from this eruption should keep the hot gas around the black hole from cooling, and some of it may also generate large-scale magnetic fields in the galaxy cluster. Chandra observers have discovered other cavities in galaxy clusters, but this one is easily the largest and the most powerful. For example, the energy content here exceeds that of the Perseus cavities by 250 times, and dwarfs the cavities in M87 by a factor of 10,000.

  9. Conflict in the Cosmos: the Hoyle-Ryle clashes

    NASA Astrophysics Data System (ADS)

    Mitton, S.

    2005-08-01

    Fred Hoyle (1915-2001) made great contributions to both astrophysics and cosmology. His work in accretion theory (1939-45) and nuclear astrophysics (1946-57) continues to be admired and widely quoted. In cosmology, the field for which he is best known among the general public, his achievement is more questionable and marked by controversy. He was the first to use the expression Big Bang to describe the evolving universes of Eddington, Lemaitre, and Gamow. He named his own theory Continuous Creation, although the expression Steady State, coined by Bondi and Gold, became associated with Hoyle's model of a universe of infinite age, infinite extent, and matter creation. By 1952 the Cambridge radio astronomer Martin Ryle (1918-84) realised that his group could join the observational cosmology game. They would use counts of radio sources to discriminate between evolution and steady state. Ryle's first two surveys were inadequate and unreliable, although he did not see it that way, believing from the outset that he had proved Hoyle wrong. The third and fourth surveys did point to an evolutionary universe, but Hoyle refused to accept this, given Ryle's earlier track record in observational cosmology. The two argued passionately for a period of 20 years in a way that came to do serious harm to the standing of astronomy in the University of Cambridge. The paper examines the reasons for the failure of the two Cambridge astronomers to be more co-operative. This research was supported by St Edmund's College, Cambridge.

  3. Chandra Provides New View of Biggest Construction Sites in Universe

    NASA Astrophysics Data System (ADS)

    2003-05-01

    Images made by NASA's Chandra X-ray Observatory have revealed two distant cosmic construction sites buzzing with activity. This discovery shows how super massive black holes control the growth of massive galaxies in the distant universe. X-rays were detected from vast clouds of high-energy particles around the galaxies 3C294 and 4C41.17, which are 10 and 12 billion light years from Earth, respectively. The energetic particles were left over from past explosive events that can be traced through the X-ray and radio jets back to the super massive black holes located in the centers of the galaxies. "These galaxies are revealing an energetic phase in which a super massive black hole transfers considerable energy into the gas surrounding the galaxies," said Andrew Fabian of England's Cambridge University, lead author of a paper on 3C294 to appear in an upcoming issue of the Monthly Notices of the Royal Astronomical Society. "This appears to be crucial in explaining the puzzling properties of present-day galaxies, especially those that group together in large clusters," he said. The picture that is emerging is of a grand cosmic cycle. A dense region of intergalactic gas cools to form several smaller galaxies, which merge to form a larger galaxy with a super massive black hole. The galaxy and its central black hole continue to grow until the energy generated by jets from the vicinity of the voracious black hole stops the fall of matter into the black hole. Millions of years after the jet activity subsides, matter will resume falling into the black hole and the cycle begins anew. 4C41.17 and 3C294 4C41.17 Both 3C294 and 4C41.17 reside in regions of space containing unusually high numbers of galaxies. The gas and galaxies surrounding these galaxies will eventually collapse to form galaxy clusters, some of the most massive objects in the universe. Although 3C294 and 4C41.17 will grow to gargantuan sizes, through the accumulation of surrounding matter that forms hundreds of billions of stars, their growth does not go unchecked. "It's as if nature tries to impose a weight limit on the size of the most massive galaxies," said Caleb Scharf of Columbia University, N.Y., and lead author of a paper on 4C41.17 to be published in The Astrophysical Journal. "The Chandra observations have given us an important clue as to how this occurs. The high energy jets give the super massive black holes an extended reach to regulate the growth of these galaxies," he said. In 3C294 and 4C41.17, the hot swirling infernos around their super massive black holes have launched magnetized jets of high energy particles first identified by radio telescopes. These jets, which were also detected by Chandra, have swept up clouds of dust and gas and have helped trigger the formation of billions of new stars. The dusty, star-forming clouds of 4C41.17, the most powerful source of infrared radiation ever observed, are embedded in even larger clouds of gas. Astronomers recently used the Keck Observatory to observe these larger clouds, which have a temperature of 10,000 degree Celsius gas. These clouds are leftover material from the galaxy's formation and should have cooled rapidly by radiation in the absence of a heat source. Animation of How Supermassive Black Holes Affect the Formation of Massive Galaxies Animation of How Supermassive Black Holes Affect the Formation of Massive Galaxies "Significantly, the warm gas clouds coincide closely with the largest extent of the X-ray emission," said Michiel Reuland of Lawrence Livermore National Laboratory, Livermore, Calif., a coauthor on the 4C41.17 paper and a paper describing Keck Observatory work. "The Chandra results show that high energy particles or radiation can supply the necessary energy to light up these clouds," he said. Most of the X-rays from 4C41.17 and 3C294 are due to collisions of energetic electrons with the cosmic background of photons produced in the hot early universe. Because these galaxies are far away, their observed radiation originated when

    Summary Background Fetal growth restriction is a major determinant of adverse perinatal outcome. Screening procedures for fetal growth restriction need to identify small babies and then differentiate between those that are healthy and those that are pathologically small. We sought to determine the diagnostic effectiveness of universal ultrasonic fetal biometry in the third trimester as a screening test for small-for-gestational-age (SGA) infants, and whether the risk of morbidity associated with being small differed in the presence or absence of ultrasonic markers of fetal growth restriction. Methods The Pregnancy Outcome Prediction (POP) study was a prospective cohort study of nulliparous women with a viable singleton pregnancy at the time of the dating ultrasound scan. Women participating had clinically indicated ultrasonography in the third trimester as per routine clinical care and these results were reported as usual (selective ultrasonography). Additionally, all participants had research ultrasonography, including fetal biometry at 28 and 36 weeks' gestational age. These results were not made available to participants or treating clinicians (universal ultrasonography). We regarded SGA as a birthweight of less than the 10th percentile for gestational age and screen positive for SGA an ultrasonographic estimated fetal weight of less than the 10th percentile for gestational age. Markers of fetal growth restriction included biometric ratios, utero-placental Doppler, and fetal growth velocity. We assessed outcomes for consenting participants who attended research scans and had a livebirth at the Rosie Hospital (Cambridge, UK) after the 28 weeks' research scan. Findings Between Jan 14, 2008, and July 31, 2012, 4512 women provided written informed consent of whom 3977 (88%) were eligible for analysis. Sensitivity for detection of SGA infants was 20% (95% CI 15–24; 69 of 352 fetuses) for selective ultrasonography and 57% (51–62; 199 of 352 fetuses) for universal ultrasonography (relative sensitivity 2·9, 95% CI 2·4–3·5, p<0·0001). Of the 3977 fetuses, 562 (14·1%) were identified by universal ultrasonography with an estimated fetal weight of less than the 10th percentile and were at an increased risk of neonatal morbidity (relative risk [RR] 1·60, 95% CI 1·22–2·09, p=0·0012). However, estimated fetal weight of less than the 10th percentile was only associated with the risk of neonatal morbidity (pinteraction=0·005) if the fetal abdominal circumference growth velocity was in the lowest decile (RR 3·9, 95% CI 1·9–8·1, p=0·0001). 172 (4%) of 3977 pregnancies had both an estimated fetal weight of less than the 10th percentile and abdominal circumference growth velocity in the lowest decile, and had a relative risk of delivering an SGA infant with neonatal morbidity of 17·6 (9·2–34·0, p<0·0001). Interpretation Screening of nulliparous women with universal third trimester fetal biometry roughly tripled detection of SGA infants. Combined analysis of fetal biometry and fetal growth velocity identified a subset of SGA fetuses that were at increased risk of neonatal morbidity.

  5. HUBBLE SPACE TELESCOPE ON TRACK FOR MEASURING THE EXPANSION RATE OF THE UNIVERSE

    NASA Technical Reports Server (NTRS)

    2002-01-01

    Two international teams of astronomers, using NASA's Hubble Space Telescope, are reporting major progress in converging on an accurate measurement of the Universe's rate of expansion -- a value which has been debated for over half a century. These new results yield ranges for the age of the Universe from 9-12 billion years, and 11-14 billion years, respectively. The goal of the project is to measure the Hubble Constant to ten percent accuracy. The Hubble Space Telescope Key Project team, an international group of over 20 astronomers, is led by Wendy Freedman of Carnegie Observatories, Pasadena, CA, Robert Kennicutt, University of Arizona, Tucson, AZ, and Jeremy Mould, Mount Stromlo and Siding Springs Observatory, Australia. The group's interim results, announced at a meeting held at the Space Telescope Science Institute (STScI) in Baltimore, Maryland, are consistent with their preliminary result, announced in 1994, of 80 kilometers per second per megaparsec (km/sec/Mpc), based on observations of a galaxy in the Virgo cluster. 'We have five different ways of measuring the Hubble Constant with HST,' said Dr. Freedman. 'The results are coming in between 68 and 78 km/sec/Mpc.' (For example, at an expansion rate of 75 km/sec/Mpc, galaxies appear to be receding from us at a rate of 162,000 miles per hour for every 3.26 million light-years farther out we look). Two months ago, a second team, led by Allan Sandage, also of the Carnegie Observatories, Abhijit Saha, STScI, Gustav Tammann and Lukas Labhardt, Astronomical Institute, University of Basel, Duccio Macchetto and Nino Panagia, STScI/European Space Agency, reported a slower expansion rate of 57 km/sec/Mpc. The value of the Hubble Constant allows astronomers to calculate the expansion age of the Universe, the time elapsed since the Big Bang. Astronomers have been arguing recently whether the time since the Big Bang is consistent with the ages of the oldest stars. The ages are calculated from combining the expansion rate with an estimate of how much matter is in space. The younger age values from each team assume the Universe is at a critical density where it contains just enough matter to expand indefinitely. The higher age estimates are calculated based on a low density of matter in space. (See 'Science Background' for more information on the expanding Universe.) 'A point of great interest is whether the age of the Universe arrived at this way is really older than the independently derived ages of the oldest stars,' said Saha, an investigator on both Hubble teams. 'The numbers lean on the side that the stellar ages are a little lower, or that the hypothesis that we live in a critical density universe needs to be questioned,' said Saha. 'As further results accumulate over the next few years, we hope to tighten the constraints on these issues.' THE OBSERVATIONS The Key Project team is midway along in their three-year program to derive the expansion rate of the Universe based on precise distance measurements to galaxies. They have now measured Cepheid distances to a dozen galaxies, and are about halfway through their overall program. The Key Project team also presented a preliminary estimate of the distance to the Fornax cluster of galaxies. The estimate was obtained through the detection and measurement with the Hubble Space Telescope of pulsating stars known as Cepheid variables found in the Fornax cluster. The Fornax cluster is measured to be approximately as far away as the Virgo cluster of galaxies -- about 60 million light-years. The Key Project team member who led this effort, Caltech astronomer Barry Madore said, 'This cluster allows us to make independent estimates of the expansion rate of the Universe using a number of different techniques. All of these methods are now in excellent agreement. With Fornax we are now at turning point in this field.' The team is measuring Cepheid distances to the Virgo and Fornax clusters of galaxies as a complementary test. Their strategy is to compare and contrast expansion numbers from a variety of distance indicators. The Key Project team is systematically looking into a variety of methods for measuring distances. They are using Cepheids in a large sample to tie into five or six 'secondary methods'. One such secondary method relates the total luminosity of a galaxy to the rate at which the galaxy is spinning, the Tully-Fisher relation. Another secondary method makes use of a special class of exploding star known as a type Ia supernova. This phase of the Hubble Constant research will be completed within another two years. In contrast, the Sandage team focused on a single secondary distance indicator, one of the same indicators also used by the Key Project team, the type Ia supernova. Sandage maintains that these stars are 'standard bombs' according to theory. He suggests that when they explode they all reach exactly the same intrinsic brightness. This would make them extremely reliable 'standard candles,' (objects with a well-known intrinsic brightness) visible 1,000 times farther away than Cepheids. Since they are intrinsically brighter than any other standard candle, they offer the opportunity for an accurate measurement of the Universe's overall expansion by looking out the farthest. Although both teams are still in disagreement over the precise rate at which the Universe is expanding and on how old it is, they are optimistic that their estimates will continue to converge with further observations and analysis. * * * * Members of the Key Project team include W.

    This special issue constitutes the Proceedings of the IUTAM Symposium on Plasticity at the Micron Scale, held at the Technical University of Denmark, 21-25 May 2006. The purpose of this symposium was to gather a group of leading scientists working in areas of importance to length scale dependent plasticity. This includes work on phenomenological strain gradient plasticity models, studies making use of discrete dislocation models, and even atomic level models. Experimental investigations are central to all this, as all the models focus on developing an improved understanding of real observed phenomena. The opening lecture by Professor N A Fleck, Cambridge University, discussed experimental as well as theoretical approaches. Also, recent results for the surface roughness at grain boundaries were presented based on experiments and crystal plasticity modelling. A number of presentations focused on experiments for metals at a small length scale, e.g. using indenters or a small single crystal compression test. It was found that there are causes of the size effects other than the geometrically necessary dislocations related to strain gradients. Several lectures on scale dependent phenomenological plasticity theories discussed different methods of incorporating the characteristic material length. This included lower order plasticity theories as well as higher order theories, within standard plasticity models or crystal plasticity. Differences in the ways of incorporating higher order boundary conditions were the subject of much discussion. Various methods for discrete dislocation modelling of plastic deformation were used in some of the presentations to obtain a more detailed understanding of length scale effects in metals. This included large scale computations for dislocation dynamics as well as new statistical mechanics approaches to averaging of dislocation plasticity. Furthermore, at a somewhat larger length scale, applications of scale dependent plasticity to granular media and to cellular solids were discussed. The symposium consisted of thirty-six lectures, all of which were invited based on strong expertise in the area. Some of the lectures are not represented in this special issue, mainly because of prior commitments to publish elsewhere. The international Scientific Committee responsible for the symposium comprised the following: Professor V Tvergaard (Chairman) Denmark Professor A Benallal France Professor N A Fleck UK Professor L B Freund (IUTAM Representative) USA Professor E van der Giessen The Netherlands Professor J W Hutchinson USA Professor A Needleman USA Professor B Svendsen Germany The Committee gratefully acknowledges financial support for the symposium from the International Union of Theoretical and Applied Mechanics, from Novo Nordisk A/S and from the Villum Kann Rasmussen Foundation. In the organization of all parts of the symposium the enthusiastic participation of Dr C F Niordson and Dr P Redanz was invaluable. The smooth running of the symposium also owes much to the efforts and organizational skills of Bente Andersen.

  11. An Explosive End to Intermediate-Mass Zero-Metallicity Stars and Early Universe Nucleosynthesis

    SciTech Connect

    2008-03-11

    We use the Cambridge stellar evolution code STARS to model the evolution of 5 M{sub {center_dot}} and 7 M{sub {center_dot}} zero-metallicity stars. With enhanced resolution at the hydrogen and helium burning shell in the AGB phases, we are able to model the entire thermally pulsing asymptotic giant branch (TP-AGB) phase. The helium luminosities of the thermal pulses are significantly lower than in higher metallicity stars so there is no third dredge-up. The envelope is enriched in nitrogen by hot-bottom burning of carbon that was previously mixed in during second dredge-up. There is no s-process enrichment owing to the lack of third dredge up. The thermal pulses grow weaker as the core mass increases and they eventually cease. From then on the star enters a quiescent burning phase which lasts until carbon ignites at the centre of the star when the CO core mass is 1.36 M{sub {center_dot}}. With such a high degeneracy and a core mass so close to the Chandrasekhar mass, we expect these stars to explode as type 1.5 supernovae, very similar to Type Ia supernovae but inside a hydrogen rich envelope.

  14. Flickering Quasar Helps Chandra Measure the Expansion Rate of the universe

    NASA Astrophysics Data System (ADS)

    2000-11-01

    Astronomers using the Chandra X-ray Observatory have identified a flickering, four-way mirage image of a distant quasar. A carefully planned observation of this mirage may be used to determine the expansion rate of the universe as well as to measure the distances to extragalactic objects, arguably two of the most important pursuits in modern astronomy. quasar RX J0911.4+0551 This figure is a composite of the X-ray image of the gravitational lens RX J0911.4+551 (top panel) and the light curves of the lensed images A2 (left panel) and A1 (right panel). Credit: NASA George Chartas, senior research associate at The Pennsylvania State University (Penn State) and Marshall W. Bautz, principal research scientist at the Massachusetts Institute of Technology (MIT) Center for Space Research, present their findings today at the meeting of the High Energy Astrophysics Division of the American Astronomical Society in Honolulu, Hawaii. "With a carefully planned follow-up, the Chandra observation of quasar RX J0911.4+0551 may lead to a measurement of the Hubble constant, the expansion rate of the universe, in less than a day," said Chartas. The observation would be done not with mirrors but with mirages--four images of a single quasar that capture the quasar's light at different moments of time due to the speed of light and the location of the mirages. Quasars are extremely distant galaxies with cores that glow with the intensity of 10 trillion Suns, a phenomenon likely powered by a supermassive black hole in the heart of the galaxy. This single "point source" image of a quasar may appear as four or five sources when the quasar--from our vantage point on Earth--is behind a massive intervening deflector, such as a dim galaxy. A mirage of images form when the gravity of the intervening deflector forces light rays to bend and take different paths to reach us. The time it takes for light to reach us from the distant object will depend on which path a ray decides to take. "An intervening galaxy can act as a lens," said Bautz. "Now imagine that the distant lensed quasar suddenly became brighter. The mirage images of the quasar will brighten up at different times depending on the difference in the light travel delay." Unlike ordinary galaxies, quasars do vary greatly in their intensity, especially in the X-ray waveband, said Gordon Garmire, Evan Pugh Professor of Astronomy and Astrophysics at Penn State. This is caused by the violent and erratic flow of gas into the black hole that is powering the quasar. In quasar RX J0911.4+0551, the astronomers saw a sudden brightening of X-ray intensity that lasted for about 2,000 seconds. This was observed in one of the four mirage images. Measuring the time-delay of the 2,000-second flare--or any flare-- from mirage to mirage can provide the absolute distance to the deflector (intervening galaxy) and can thus be used to estimate the expansion rate of the universe. Sjur Refsdal first proposed this promising method in 1964. The method avoids many uncertainties associated with the classic distance-ladder technique used to measure objects and the Hubble constant. The main difficulty in measuring time-delays is that the brightness of each image has to be carefully monitored over several periods of the time-delay. Also, the quasar has to show sufficient variability over time scales smaller than the time-delay. Most attempts to measure time-delays until now have been made in the optical and radio bands. The modest variability of quasars in these wavebands, however, has made it extremely difficult to place accurate constraints on time-delays. X-ray observations of gravitationally lensed quasars, on the other hand, show strong variability over time scales of hours to days. For example, it has taken almost 20 years of optical and radio monitoring to obtain a universal accepted time-delay for the lensed quasar Q0957+561 to an accuracy of 3percent. Chandra has the potential, the team has found, to determine the time-delay in one observation. "Based on computer models developed at Penn State and MIT, we have identified about ten gravitational lens systems with time-delays of less than a day," said Chartas. "One long observation of each source with a superior X-ray telescope could provide enough data to nail down the Hubble constant in the blink of an eye." The team is planning to apply the gravitational-lens method in the near future to several of these systems using the Chandra and XMM-Newton X-ray observatories. The Chandra observations of quasar RX J0911.4+0551 were made on November 2, 1999, using the Advanced CCD Imaging Spectrometer (ACIS). The effort involved several scientists from Penn State and MIT. ACIS was conceived and developed for NASA by Penn State and MIT under Garmire's leadership. NASA's Marshall Space Flight Center in Huntsville, Alabama, manages the Chandra program. TRW, Inc., in Redondo Beach, California, is the prime contractor for the spacecraft. The Smithsonian's Chandra X-ray Center controls science and flight operations from Cambridge, Massachusetts.

  8. Reflective scientific sense-making dialogue in two languages: The science in the dialogue and the dialogue in the science

    NASA Astrophysics Data System (ADS)

    Ash, Doris

    2004-11-01

    In this paper I focus on the transition from everyday to scientific ways of reasoning, and on the intertwined roles of meaning-making dialogue and science content as they contribute to scientific literacy. I refer to views of science, and how scientific understanding is advanced dialogically, by Hurd (Science Education, 1998, 82, 402-416), Brown (The Journal of Learning Sciences, 1992, 2(2), 141-178), Bruner (Acts of Meaning, Cambridge, MA: Harvard University Press, 1990), Roth (In J. Brophy (Ed.), Social Constructivist Teaching: Affordances and Constraints (Advances in Research on Teaching Series, Vol. 9), New York: Elsevier/JAI, 2003), and Wells (Dialogic Inquiry: Towards a Sociocultural Practice and Theory of Education, New York: Cambridge University Press, 1999). I argue that family collaborative dialogues in nonschool settings can be the foundations for scientific ways of thinking. I focus on the particular reflective family dialogues at the Monterey Bay Aquarium, when family members remembered and synthesized essential biological themes, centering on adaptation, from one visit to the next, in both Spanish and English. My approach is informed by sociocultural theory, with emphasis on the negotiations of meaning in the zone of proximal development (Vygotsky, 1978), as learners engage in joint productive activity (Tharp & Gallimore, Rousing Minds to Life: Teaching, Learning and Schooling in Social Context, New York: Cambridge University Press, 1988). Over the past decades, researchers have discovered that observing social activity, conversation, and meaning-making in informal settings (Crowley & Callanan, 1997; Guberman, 2002; Rogoff, 2001; Vasquez, Pease-Alvarez, & Shannon, Pushing Boundaries: Language and Culture in a Mexicano Community, New York: Cambridge University Press, 1994) has much to teach us regarding learning in general. To date there has been little research with Spanish-speaking families in informal learning settings and virtually none that integrates the home with both formal and informal learning.

    Universe Awareness (UNAWE) is an educational programme coordinated by Leiden University that uses the beauty and grandeur of the Universe to encourage young children, particularly those from an underprivileged background, to have an interest in science and technology and foster their sense of global citizenship from the earliest age.UNAWE's twofold vision uses our Universe to inspire and motivate very young children: the excitement of the Universe provides an exciting introduction to science and technology, while the vastness and beauty of the Universe helps broaden the mind and stimulate a sense of global citizenship and tolerance. UNAWE's goals are accomplished through four main activities: the coordination of a global network of more than 1000 astronomers, teachers and educators from more than 60 countries, development of educational resources, teacher training activities and evaluation of educational activities.Between 2011 and 2013, EU-UNAWE, the European branch of UNAWE, was funded by the European Commission to implement a project in 5 EU countries and South Africa. This project has been concluded successfully. Since then, the global project Universe Awareness has continued to grow with an expanding international network, new educational resources and teacher trainings and a planned International Workshop in collaboration with ESA in October 2015, among other activities.

    These Proceedings are dedicated to our co-editor Konrad Bajer, who carried the lion's share of the work involved until his sudden and untimely death from cancer on 29th August 2014. Konrad was one of the key Organisers of the program "Topological Dynamics in the Physical and Biological Sciences" held at the Isaac Newton Institute for Mathematical Sciences in Cambridge from July to December 2012. During that time, he was on leave from the University of Warsaw, and held a Visiting Fellow Commonership at Trinity College, Cambridge. He had particular responsibility for the satellite workshop Tangled Magnetic Fields in Astro- and Plasma Physics, held at ICMS, Edinburgh, in October 2012. Konrad graduated in Physics from the University of Warsaw in 1980, and took his PhD in Fluid Dynamics at DAMTP, Cambridge, 1984-89. He was active in EUROMECH, having been a principal organiser of the European Turbulence Conference (ETC13) in Warsaw 2011, and the meeting Turbulence: the Historical Perspective that followed it. He has been equally active in IUTAM; his distinction was recognised by his very recent election to the Congress Committee of IUTAM. Konrad's research interests were in magnetohydrodynamics and vortex dynamics in classical and quantum systems; also in problems of gasifcation, in which he played a coordinating role at the University of Warsaw. He impressed all with his exceptionally warm and friendly personality, and will be greatly missed in the whole scientifc community.

  18. Beagle I and II Voyages: Charles Darwin's rocks and the quest for Mars rock; the Open University's virtual microscope has both

    Exploration is in itself a fascinating subject, and a strong draw to engaging the public in understanding science. Nearly two hundred years ago Charles Darwin took part in an exploration of the Earth, and more recently we have begun to explore the solar system and in particular the surface of Mars. The engagement is made easier if an element of exploration is involved in the public engagement, using modern internet and even mobile technologies. The Open University combines all those aspects in a series of virtual microscopes for Earth science that are freely available on the web, installed in museums, or built into its teaching material. The basis of the virtual microscope is a mosaic of several hundred microscopic images of each thin section taken in plane polarised light, between crossed polars and in reflected light, which are then assembled into three high resolution images. Rotation movies for selected points in the thin section illustrate changing optical properties such as birefringence. The user is able to pan and zoom around to explore the section, studying the mineralogy and rock texture, and view the rotation movies linked to points in the section to see the changing birefringence colours. We have created several collections of terrestrial rocks, mainly for teaching purposes, and outreach directly linked to exploration: Charles Darwin returned from the Voyage of the Beagle with a large variety of rock samples, and although thin sections were not being made at that time, they were created from his rocks in the late 19th century. The historic material is part of the "Darwin the Geologist" exhibition at the Sedgwick Museum in Cambridge. Our Darwin virtual microscope includes hand specimen illustrations and thin sections together with documentation and an interactive map allow internet users and museum visitors alike to have a close look at Darwin's rocks and study the petrology of them. Charles Darwin explored distant horizons on Earth in the 19th century; in the 20th century the Apollo astronauts set foot on the Moon, returning valuable rock samples to Earth. Through collaboration between NASA and the OU it became possible to show lunar samples as virtual thin sections. The Beagle II mission represented a new voyage, following Charles Darwin's footsteps, to horizons well beyond the Earth - on a journey to investigate the planet Mars. Although no samples have yet been returned from the red planet, we do have access to Martian meteorites. Like Moon rock samples, these meteorites are rare and very valuable. So, one way to make them accessible to the general public is via the internet using our virtual microscope technology. Within the framework of the EUROPLANET project, and in collaboration with the Natural History Museum in London we are making such meteorites freely available to all. We plan to extend this collection and make it openly accessible for teaching and outreach activities anywhere and any time. Our current microscopes are located at http://microscope.open.ac.uk.

While the Universe is evolving, there is no beginning and no end—the Universe exists forever. The early state of inflation is described in two different, but equivalent pictures. In the freeze frame the Universe emerges from an almost static state with flat geometry. After entropy production it shrinks and "thaws" slowly from a "freeze state" with extremely low temperature. The field transformation to the second "big bang picture" (Einstein frame) is singular. This "field singularity" is responsible for an apparent singularity of the big bang. Furthermore, we argue that past-incomplete geodesics do not necessarily indicate a singularity or beginning of the Universe. Proper time ceases to be a useful concept for physical time if particles become massless. We propose to define physical time by counting the number of zeros of a component of the wave function. This counting is independent of the choice of coordinates and frames, and applies to massive and massless particles alike.

  20. Plasma universe

    Traditionally the views on the cosmic environent have been based on observations in the visual octave of the electromagnetic spectrum, during the last half-century supplemented by infrared and radio observations. Space research has opened the full spectrum. Of special importance are the X-ray-gamma-ray regions, in which a number of unexpected phenomena have been discovered. Radiations in these regions are likely to originate mainly from magnetised cosmic plasmas. Such a medium may also emit synchrotron radiation which is observable in the radio region. If a model of the universe is based on the plasma phenomena mentioned it is found that the plasma universe is drastically different from the traditional visual universe. Information about the plasma universe can also be obtained by extrapolation of laboratory experiments and magnetospheric in situ measurements of plasmas. This approach is possible because it is likely that the basic properties of plasmas are the same everywhere. In order to test the usefulness of the plasma universe model it is applied to cosmogony. Such an approach seems to be rather successful. For example, the complicated structure of the Saturnian C ring can be accounted for. It is possible to reconstruct certain phenomena 4 to 5 billions of years ago with an accuracy of better than 1%.

  2. Reconsideration of contemporary U.S. drug policy.

    In their recent book Drug War Heresies: Learning From Other Vices, Times, and Places (Cambridge: Cambridge University Press, 2001), MacCoun and Reuter challenge the continuation of contemporary U.S. drug policy. Depenalization and legalization of illicit drugs are evaluated as alternatives to U.S. prohibition policy, with harm reduction (mitigation of social damages) as the criterion for guiding drug regime change. The appraisal encompasses an analysis of underlying philosophical and social mechanisms of current U.S. policy as well as drawing analogies from a comprehensive review of American vices and also Western European governmental interventions into illicit drug activities. What is apparent is that the evaluation and the available evidence entail substantial complexity and do not readily present unequivocal positions. The evaluation also strongly indicates that considerable difficulty would be encountered not only for the implementation of alternative regimes but also for the engagement in open political discussion of prohibition alternatives.

  3. Ask not what physics can do for biology—ask what biology can do for physics

    Stan Ulam, the famous mathematician, said once to Hans Frauenfelder: ‘Ask not what Physics can do for biology, ask what biology can do for physics’. The interaction between biologists and physicists is a two-way street. Biology reveals the secrets of complex systems, physics provides the physical tools and the theoretical concepts to understand the complexity. The perspective gives a personal view of the path to some of the physical concepts that are relevant for biology and physics (Frauenfelder et al 1999 Rev. Mod. Phys. 71 S419-S442). Schrödinger’s book (Schrödinger 1944 What is Life? (Cambridge: Cambridge University Press)), loved by physicists and hated by eminent biologists (Dronamraju 1999 Genetics 153 1071-6), still shows how a great physicist looked at biology well before the first protein structure was known.

  4. Stacking up against alternative conceptions: using Uno cards to introduce discourse and argumentation

    We engaged secondary science students in a teacher and student constructed Uno card game (UCG) to change their conceptual understanding of the various energy transformations. The paper outlines how we incorporated Toulmin’s argumentation pattern (Toulmin 1958 The Uses of Argument (Cambridge: Cambridge University Press)) in the UCG, using discourse (Erduran et al 2004 Sci. Educ. 88 915-33) and through a 5E learning cycle (Bybee 1997 Achieving Scientific Literacy: From Purposes to Practices (Portsmouth, NH: Heinemann Educational Books)). The activity helped students develop a deeper understanding of the energy transformation among and between different sources. Students experienced a conceptual gain in their ways of thinking, in contrast to traditional teaching and learning practices. The collaboration and interaction between teacher-student(s) and between students fostered an environment where they became co-constructors of knowledge.

    During the first half of the 20th Century, Joseph Barcroft, KBE, FRS of Cambridge University became a world leader in respiratory physiology. He determined the role of neural stimulation in the oxygen consumption of several organs, established many of the factors that regulate the binding of oxygen to haemoglobin, explored the determinants of a human's acclimatization to high altitude and developed the field of fetal cardiovascular physiology. Chair of the Cambridge Department of Physiology from 1925 to 1937, he served as a consultant and member of many UK governmental committees. During World War I, he led a British research unit exploring the effects of poisonous gases on pulmonary function and related problems. In addition to his almost 300 publications, several of his monographs are considered as classics. PMID:25929679

    Carbon Nanotubes exhibit conducting and semi-conducting behaviour depending on the tube chirality. When bundled together in ropes, tunnelling between nanotubes of different chiralities is heavily suppressed due to energy momentum conservation[1][2]. We investigate the effects of a scattering potential on the tunnelling between finite length metallic tubes of different chiralities using a Green's function method[3]. We find a large increase in inter-tube conductance due to a single vacancy and compare this with other mechanisms for loss of momentum conservation.

    This manuscript deals with the generalisation of all previous works on series solutions and linear stability of equilibrium points of the Sitnikov problem. Following Giacaglia (1967), in Sect. 2 we have derived the equation of motion of the infinitesimal mass moving along the z-axis about which the plane of motion is rotating with unit angular velocity. In Sects. 3, 4 and 5 the series solutions of the Sitnikov problem have been developed by the method of MacMillan, Lindstedt-Poincaré and iteration of Green's function respectively. In Sect. 6 the three series solutions have been compared graphically by putting N=2, 3, 4. In Sect. 7 the coordinates of equilibrium points have been calculated. In Sect. 8 the linear stability of equilibrium points has been examined by the method of Murray and Dermott (Solar System Dynamics, Cambridge University Press, Cambridge, 1999) and it was found that the equilibrium points are stable in Sitnikov problem.

    The objective of the DEBIB project (Dynamic Energy Budgets in Bivalves) was to combine the French expertise of bivalve ecophysiology and modelling with the Dutch expertise in ecology and modelling to achieve the development of a general framework based on Dynamic Energy Budgets [Kooijman, S.A.L.M., 2000. Dynamic Energy and Mass Budgets in Biological Systems. Cambridge University Press, Cambridge] for the analysis of the functioning of bivalve species (growth, reproduction) in relation to the environmental conditions (water temperature, food conditions). The collaboration has yielded promising insights for studying life strategies of different bivalve species sharing the same resources and new perspectives (i) for coupling ecophysiological models with population dynamics and ecosystem approaches and (ii) for addressing important issues such as carrying capacity, trophic interactions between bivalves and sustainability of shellfish resources. Fields for future research include improvement of parameter estimation procedures and analysis of intraspecies variability in parameters.

    In the last few decades, the exploration of our solar system has revealed fascinating details about the worlds that lie beyond our Earth. This lavishly illustrated book invites the reader on a journey through the solar system. After locating our planetary system in the Universe, Brunier describes the Sun and its planets, the large satellites, asteroids, and comets. Photographs and information taken from the latest space missions allow readers to experience spectacular scenes: the lunar plains scarred by asteroid impacts, the frozen deserts of Mars and Europa, the continuously erupting volcanoes of Io and the giant geysers of Triton, the rings of Saturn and the clouds of Venus and Titan, and the powerful crash of the comet Shoemaker-Levy into Jupiter. Inspired by the extraordinary photographs and incisive text, readers of Solar System Voyage will gain a greater appreciation of the hospitable planet we call home. Serge Brunier is chief editor of the journal Ciel et Espace, a photojournalist, and the author of many nonfiction books aimed at both specialists and the general public. His previous books include Space Odyssey (Cambridge, 2002), Glorious Eclipses with Jean-Pierre Luminet (Cambridge, 2000), and Majestic Universe (Cambridge, 1999).

    A way to separate irreducible unitary representations ? for a Lie group G by moment sets is to use an infinite-dimensional overgroup G˜ and extensions of each representation ? to a representation ?˜ of G˜, in such a manner that the moment set of ?˜ characterizes ?. In this paper we propose a universal overgroup G˜, which is an infinite-dimensional Fréchet-Lie group. We extend each ? to a Hamiltonian action ?˜ of G˜. The moment set of ?˜ characterizes ?.
