    Graphene has attracted substantial attention due to its advantageous materialistic applicability. In the present study, we tested the biocompatibility of graphene films synthesized by chemical vapor deposition with electrogenic primary adult cardiac cells (cardiomyocytes) by measuring the cell properties such as cell attachment, survival, contractility and calcium transients. The results show that the graphene films showed stable cell attachment and excellent biocompatibility with the electrogenic cardiomyocytes, suggesting their useful applications for future cell biology studies.

    Women with attachment insecurity have greater eating disorder symptoms and poorer prognosis. Socio-cultural agents, such as peers and family, are predictive of the development of body image dissatisfaction (BID). The present study examines the association of insecure attachment styles and direct and indirect social comparisons of body image to women's BID and drive to thinness. Two hundred and eighty three women aged 18-42?years completed online self-reports concerning attachment styles, body mass index (BMI), drive for thinness, body image satisfaction, the Figure Rating Scale (FRS), as well as a modified FRS comparing self to mother, to sister closest in age and to best friend. Hierarchical Linear Models reveal that anxious-ambivalent, but not avoidant attachment style, along with indirect and direct comparisons to best friend and to sister influence drive for thinness and body dissatisfaction, even after controlling for BMI and age. Of all social comparisons, feeling one's best friend is thinner than yourself is the most detrimental to body ideal. PMID:25257536

    To clarify how Borrelia miyamotoi is maintained in the environment in Hokkaido, we examined Ixodes persulcatus for its prevalence among wild rodents and its tick vector by detecting a portion of the borrelial flaB gene in rodent urinary bladder and blood samples, and from whole ticks. We compared B. miyamotoi infection rates to Borrelia garinii and Borrelia afzelii, which are human Lyme disease pathogens also carried by wild rodents, and which are transmitted by the same vector tick. Whereas B. garinii and B. afzelii showed age dependence of infection rates among wild rodents (18.4% and 9.9% among adults and 6.0% and 3.4% among sub-adults, respectively) when looking at urinary bladder samples, B. miyamotoi infection rates were not age dependent for either blood (4.2% among adults, and 7.9% among sub-adults) or urinary bladder samples (1.0% among adults, and 1.7% among sub-adults). Moreover, while B. garinii and B. afzelii infection rates showed increases across months (June, July [p<0.05] and August [p<0.01] had higher rates than in May for adult rodents with B. garinii, and July and August had higher rates than in May [p<0.01] for adult rodents with B. afzelii), B. miyamotoi infection rates did not show significant month dependence. These differences in month and age dependence led us to suspect that B. miyamotoi may not develop persistent infections in wild rodents, as B. garinii and B. afzelii are thought to. Furthermore, we examined the extent of rodent exposure to I. persulcatus nymphs and larvae throughout most of the tick's active season (May through September), and determined that B. miyamotoi infection rates in sub-adult rodents were correlated with larval burden (p<0.01), suggesting that larvae may be very important in transmission of B. miyamotoi to wild rodents.

    SDS-PAGE is one of the most powerful experimental techniques used for the separation of proteins, and most proteins are separated according to their molecular size by this technique. However, exceptional proteins showing abnormal behavior in SDS-PAGE gels are known to exist. Thermal aggregation, rarely observed with membrane proteins, is one of the exceptional behaviors of proteins during SDS-PAGE, but detailed characterization of this aggregation has not yet been achieved. In the present study, we found that a putative membrane protein, TMEM45B, very clearly showed properties of thermal aggregation when it was expressed in COS7 cells and subjected to SDS-PAGE. We dissected the region of TMEM45B responsible for this aggregation, and found that of the seven putative transmembrane domains, a region comprising the 4th to 7th ones was essential for the thermal aggregation properties. We also demonstrated that these transmembrane domains, 4th to 7th, of TMEM45B conferred thermal aggregation properties on other proteins, by fusing this amino acid sequence to target proteins. The molecular mechanism causing thermal aggregation by TMEM45B is still uncertain, but TMEM45B could be utilized as a nice model to show clear thermal aggregation in SDS-PAGE gels. PMID:21277373

  5. An attachment perspective on psychopathology

    MIKULINCER, MARIO; SHAVER, PHILIP R.

    2012-01-01

    In recent years, attachment theory, which was originally formulated to describe and explain infant-parent emotional bonding, has been applied to the study of adolescent and adult romantic relationships and then to the study of psychological processes, such as interpersonal functioning, emotion regulation, coping with stress, and mental health. In this paper, we offer a brief overview of the attachment perspective on psychopathology. Following a brief account of attachment theory, we go on to explain how the study of individual differences in adult attachment intersects with the study of psychopathology. Specifically, we review research findings showing that attachment insecurity is a major contributor to mental disorders, and that the enhancement of attachment security can facilitate amelioration of psychopathology.

    Adult attachment representations have been considered to play a role in the development and treatment of somatizing behavior. In this study, the associations between the two attachment dimensions avoidance and anxiety and dimensions of psychopathology (somatization, depression, and general anxiety) were explored. The sample consists of 202 outpatients diagnosed with a somatoform disorder. Data were collected via self-report measures. A path analysis shows that the two attachment dimensions are not directly associated with somatization. There are, however, significant indirect associations between attachment and somatization mediated by depression and general anxiety, which are more pronounced for attachment anxiety than for attachment avoidance. The findings reveal that a low level of attachment security in romantic relationships, especially an anxious stance toward the partner, comes along with poor mental health, which in turn is related to a preoccupation with somatic complaints. Implications for the treatment of somatizing patients are discussed. PMID:25594785

    2004-01-01

    Electron attachment to PSCl3 was studied in 133-Pa pressure of helium gas at temperatures from 298-550 K. Measurements of rate constants and branching fractions were made in a flowing-afterglow Langmuir-probe (FALP) apparatus. These experiments yielded an electron attachment rate constant of 5.1 x 10(-8) cm3 s(-1) that was found not to change significantly in the 298-550 K temperature range. This rate constant represents an attachment efficiency of about 14%. Attachment in 133 Pa of He gas yielded only the dissociative ion products PSCl2- and Cl-. The FALP data suggest that there is an activation energy of about 17 meV for production of PSCl2-. Attachment to PSCl3 was also studied at high pressure (9-93 kPa) of N2 in an ion mobility mass spectrometer, at 298 K. In contrast to the low-pressure data, the parent anion product channel (PSCl3-) was observed (along with the dissociative channels), and increased in importance with N2 pressure. Gaussian-3 (G3) calculations were carried out for PSCl3 and PSCl2 neutrals and anions to aid in interpretation of the experimental results. The calculations indicate that the electron affinity EA(PSCl2) is slightly smaller than EA(Cl), which may account for the observed branching fractions for PSCl2- and Cl- in the low-pressure experiments. A natural population analysis was performed to obtain the charges associated with each atom in the molecules in order to estimate how the attached electron is distributed. Comparison is made between the present study of electron attachment to PSCl3 and our earlier work on attachment to POCl3, and G3 calculations are reported here for neutral and anionic POCl2 and POCl3. In contrast to PSCl2, the calculations imply that EA(POCl2) is slightly greater than EA(Cl). For both PSCl3 and POCl3, the calculations show that the dissociative electron attachment process is close to thermoneutral. PMID:15267279

  5. The reversibility of virus attachment to mineral surfaces

    USGS Publications Warehouse

    Loveland, J.P.; Ryan, J.N.; Amy, G.L.; Harvey, R.W.

    1996-01-01

    Virus transport through groundwater is limited by attachment to mineral surfaces and inactivation. Current virus transport models do not consider the implications of the reversibility of virus attachment to minerals. To explore the reversibility of virus attachment to mineral surfaces, we attached PRD1, a bacteriophage considered to be a good model of enteric viruses, to quartz and ferric oxyhydroxide-coated quartz surfaces over a range of pH values in equilibrium 'static columns'. Following attachment, we detached the viruses by replacing the pore solution with solutions of equal and higher pH. The extent of virus attachment followed an attachment 'edge' that occurred at a pH value about 2.5-3.5 pH units above the pH(IEP) of the mineral surfaces. Viruses attached below this edge were irreversibly attached until the pH of the detachment solution exceeded the pH value of the attachment edge. Viruses attached above this edge were reversibly attached. Derjaguin-Landau-Verwey-Overbeek (DEVO) potential energy calculations showed that the attachment edge occurred at the pH at which the potential energy of the primary minimum was near zero, implying that the position of the primary minimum (attractive or repulsive) controlled the equilibrium distribution of the viruses. The results suggest that the reversibility of virus attachment must be considered in virus transport models for accurate predictions of virus travel time.

    The purposes of the present research were to examine the relationship between attachment and extradyadic sex and to investigate a mediator of this relationship. Study 1 showed that attachment avoidance was positively associated with extradyadic sex, while attachment anxiety was unrelated to it. These results were maintained after controlling for sexual satisfaction, sexual desire, gender, and age. Study 2 replicated

    A conceptual model derived from attachment theory was tested by examining adult attachment style, cognitive distortions, and both general and victim empathy in a sample of 61 paroled child molesters and 51 community controls. Results of logistic multiple regression showed that attachment anxiety, cognitive distortions, high general empathy but low victim empathy significantly increased the odds of child molester status. Findings supported theoretically based hypotheses, suggesting that attachment theory may be useful in the conceptualization and treatment of child molesters. PMID:18162640

    Attachment style is the dispositional way in which a person relates to others, and differences in attachment characteristics may offer insight into why many women do not adhere to breast screening guidelines. While mammograms involve contact with medical professionals, breast self-examination (BSE) does not, and may be preferable for women who dislike interpersonal vulnerability. As such, differences in the attachment characteristics that predict mammography versus BSE utilisation may indicate whether attachment related motivations are relevant to both interpersonal examinations and independent self-care behaviours. The current report examined how attachment dimensions predicted the frequency of mammography and BSE in a sample of 1204 ethnically diverse women from Brooklyn, New York. Participants completed measures of mammography and BSE frequency, and attachment, together with demographic, health care context and emotional predictors of screening. Multiple regressions showed that attachment dimensions predicted both mammography and BSE screening even when controlling for established predictors and emotion relevant variables. As hypothesised, fearful avoidance predicted fewer mammograms and BSEs, while preoccupation predicted more frequent BSEs. Consistent with some prior work in male cancer screening, greater attachment security also predicted fewer mammograms while degree of dismissiveness was not associated with screening frequencies. Understanding the psychosocial predictors of screening may help identify low screeners, and guide the development of targeted interventions that are better suited to the interpersonal preferences of older women.

    Continuity in attachment classification from infancy to late adolescence was examined and related to autobiographical memories of childhood, divorce, and maladjustment. Eighty-four White middle-class children (48 girls) were seen in a modified Strange Situation at 12 months and given the Adult Attachment Interview at 18 years. In addition, data were collected on 13-year-olds' childhood recollections as well as adolescent, mother, and teacher ratings of maladjustment at 13 and 18 years of age. Divorce status of parents also was obtained. Results indicated no continuity in attachment classification from 1 to 18 years of age and no relation between infant attachment status and adolescent maladjustment. Divorce was related to 13-year-olds' childhood recollections as well as to insecure attachment status at 18 years. Eighteen-year-olds with insecure attachment classification were more likely to rate themselves as maladjusted. The results support the idea of attachment as an evolving representation dependent upon the nature of the family environment as indexed by divorce. PMID:10953938

    2007-01-01

    We show how preferential attachment can emerge in an optimization framework, resolving a long-standing theoretical controversy. We also show that the preferential attachment model so obtained has two novel features, saturation and viability, which have natural interpretations in the underlying network and lead to a power-law degree distribution with exponential cutoff. Moreover, we consider a generalized version of this preferential attachment model with independent saturation and viability, leading to a broader class of power laws again with exponential cutoff. We present a collection of empirical observations from social, biological, physical, and technological networks, for which such degree distributions give excellent fits. We suggest that, in general, optimization models that give rise to preferential attachment with saturation and viability effects form a good starting point for the analysis of many networks.

    We have studied alveolar attachments to membranous bronchioles in 41 patients enrolled in the National Institutes of Health Intermittent Positive Pressure Breathing Trial who died, came to autopsy, and provided adequate tissue for examination. The patients had moderate to severe chronic airflow obstruction and, on the average, severe emphysema. We measured the number of normal attachments per membranous bronchiole per case (N), the number of normal attachments per mm of circumference per bronchiole per case (Nunit), and the ratio of abnormal to all attachments (R). All measurements correlated closely to all measurements of emphysema and to irregular shape of bronchioles (deformity index). Measurement of abnormal attachments correlated with abnormal tests of pulmonary function, including evidence of airflow obstruction and diffusing capacity for carbon monoxide (DLCO). Nunit showed the most frequent correlations, but both N and Nunit were only related independently of emphysema for Phase III of the single-breath nitrogen test. R was related to loss of DLCO. We conclude that loss of attachments is not itself a cause of airflow obstruction but rather a correlate of emphysema, which is the proximate cause of the obstruction. Loss of alveolar attachments has an effect only on the single-breath nitrogen tests independent of emphysema. PMID:1928967

    2012-01-01

    This study examined the relationship between individual differences in adult attachment and skin barrier recovery. Dating couples (N = 34) completed a self-report measure of attachment anxiety and avoidance, and during two separate laboratory visits, normal skin barrier function was disrupted using a tape-stripping procedure, followed by a 20 min discussion of personal concerns in one visit and relationship problems in the other, counterbalanced randomly across visits. Skin barrier recovery was assessed by measuring transepidermal water loss up to 2 h after skin disruption. Multilevel modeling showed that skin barrier recovery did not differ between the personal concern or relationship problem discussions. Among women, greater attachment anxiety predicted faster skin barrier recovery across the two visits, while greater attachment avoidance predicted slower skin barrier recovery. Among men, greater attachment anxiety predicted slower skin barrier recovery during the personal concern discussion only. The observed effects remained significant after controlling for transepidermal water loss in undisturbed skin, suggesting that the relationship between attachment security and skin barrier recovery was not due to other skin-related factors like sweating. Cortisol changes, self-reported emotions, stress appraisals, and supportiveness ratings were tested as potential mediators, and none explained the relationships between attachment and skin barrier recovery. These findings are the first to demonstrate associations between individual differences in attachment style and restorative biological processes in the skin, even in a sample of young dating couples in satisfied relationships.

    1969-01-01

    An analysis of 98 health visitors and district nurses attached and non-attached to general practitioners in three local authority areas showed that most of them were aged over 40 and that many had entered domiciliary work because of the convenient hours or because of its intangible attractions. Adequate preparation for attachment was considered important, particularly a clear definition of the roles of the attached staff and their relationships to other workers in the practice. Attached staff were found to be much more satisfied with the information given by the general practitioner about their patients than were unattached staff, and the former usually had access to the patients' medical records. The principal advantages of attachment were listed as access to family history; improved co-ordination within the practice and co-operation with the social services; favourable patient response; and increased mileage and work-load; the impossibility of crossing local authority boundaries; and having to deal with families registered with more than one doctor.

    Vertices of an affiliation network are linked to attributes and two vertices are declared adjacent whenever they share a common attribute. For example, two customers of an internet shop (or video-sharing website) are called adjacent if they have purchased (or downloaded) the same or similar items. Assuming that each newly arrived customer is linked preferentially to already popular items we obtain a preferred attachment affiliation network that evolves in time. We show that the fraction of customers having neighbours scales as for large . Here is the ratio between the two intensities: intensity of the flow of customers and that of the newly arriving items.

    2014-06-01

    Many types of social attachments can be observed in nature. We discuss the neurobiology of two types (1) intraspecific (with a partner) and (2) parental (with the offspring). Stimuli related to copulation facilitate the first, whereas pregnancy, parturition and lactation facilitate the second. Both types develop as consequence of cohabitation. These events seem to stimulate similar neural pathways that increase (1) social recognition, (2) motivation, reward; and (3) decrease fear/anxiety. Subregions of the amygdala and cortex facilitate social recognition and also disinhibition to decrease rejection responses. The interrelationship between MeA, BNST, LS may mediate the activation of NAcc via the mPOA to increase motivation and reward. Cortical areas such as the ACC discriminate between stimuli. The interaction between OT and D2-type receptors in NAcc shell facilitates intraspecific attachment, but D1-type appears to facilitate parental attachment. This difference may be important for maternal females to direct their attention, motivation and expression of attachment toward the appropriate target. PMID:24769402

    2014-01-01

    Background Based on Bowlby's attachment theory, Bartholomew proposed a four-category attachment typology by which individuals judged themselves and adult relationships. This explanatory model has since been used to help explain the risk of psychiatric comorbidity. Objective The current study aimed to identify attachment typologies based on Bartholomew's attachment styles in a sample of bereaved parents on dimensions of closeness/dependency and anxiety. In addition, it sought to assess the relationship between the resultant attachment typology with a range of psychological trauma variables. Method The current study was based on a sample of 445 bereaved parents who had experienced either peri- or post-natal death of an infant. Adult attachment was assessed using the Revised Adult Attachment Scale (RAAS) while reaction to trauma was assessed using the Trauma Symptom Checklist (TSC). A latent profile analysis was conducted on scores from the RAAS closeness/dependency and anxiety subscales to ascertain if there were underlying homogeneous attachment classes. Emergent classes were used to determine if these were significantly different in terms of mean scores on TSC scales. Results A four-class solution was considered the optimal based on fit statistics and interpretability of the results. Classes were labelled “Fearful,” “Preoccupied,” “Dismissing,” and “Secure.” Females were almost eight times more likely than males to be members of the fearful attachment class. This class evidenced the highest scores across all TSC scales while the secure class showed the lowest scores. Conclusions The results are consistent with Bartholomew's four-category attachment styles with classes representing secure, fearful, preoccupied, and dismissing types. While the loss of an infant is a devastating experience for any parent, securely attached individuals showed the lowest levels of psychopathology compared to fearful, preoccupied, or dismissing attachment styles. This may suggest that a secure attachment style is protective against trauma-related psychological distress. PMID:24839541

    2012-01-01

    Root climbers such as English ivy (Hedera helix) rely on specialized adventitious roots for attachment, enabling the plants to climb on a wide range of natural and artificial substrates. Despite their importance for the climbing habit, the biomechanical properties of these specialized adventitious roots compared with standard roots and their performance in the attachment to different host species or inert substrates have not been studied. Here organs and tissues involved in the attachment are characterized and their significance in regard to a broader functional and ecological aspect is discussed. Depending on the substrate, the root clusters show different types of failure modes at various frequencies, demonstrating the close interaction between the climber and its substrates. With a Young’s Modulus of 109.2?MPa, the attachment roots are relatively stiff for non-woody roots. The central cylinders of the attachment roots show a high tensile strength of 38?MPa and a very high extensibility of 34%. In host trees naturally co-distributed with English ivy, a ‘balanced’ occurrence of failure of the attachment system of the climber and the bark of the host is found, suggesting a co-evolution of climber and host. Maximum loads of root clusters normalized by the number of roots match those of individually tested attachment roots. In comparison with most subterranean roots the properties and structure of the attachment roots of English ivy show distinct differences. There exist similarities to the properties found for roots of Galium aparine, suggesting a trend in not fully self-supporting plants towards a higher extensibility. PMID:21914660

    Giardia lamblia is a protozoan parasite responsible for widespread diarrheal disease in humans and animals worldwide. Attachment to the host intestinal mucosa and resistance to peristalsis is necessary for establishing infection, but the physical basis for this attachment is poorly understood. We report results from confocal fluorescence microscopy that demonstrate that the regular beating of the posterior flagella generate a flow through the ventral disk, a suction-cup shaped structure that is against the substrate during attachment. Finite element simulations show that the negative pressure generated by the flow is consistent with the measured force of attachement between the parasite and its substrate.

    A group of sex offenders (clinical group: n = 19) was compared to a nonclinical sample matched by age, years of education, and gender (control group A: n = 19) to verify a higher incidence of insecure attachment models among sex offenders. In addition, we tested whether sex offenders were characterized by specific childhood experiences, compared to control adults (control group B: n = 19) with the same secure/insecure attachment classification. Results showed significant differences between offenders and control adults on both the AAI continuous score and the distribution of the two-way attachment classifications. Furthermore, sex offenders reported more intense experiences of rejection by the father figure and abuse in the family context during early childhood compared to not offenders subjects with the same attachment classification.

    Utada, Andrew; Gibiansky, Maxsim; Wong, Gerard

    Vibrio cholerae is a gram-negative bacterium that causes the human disease cholera. It is found natively in brackish costal waters in temperate climates, where it attaches to the surfaces of a variety of different aquatic life. V. cholerae has a single polar flagellum making it highly motile, as well as a number of different pili types, enabling it to attach to both biotic and abiotic surfaces. Using in-house built tracking software we track all surface-attaching bacteria from high-speed movies to examine the early-time attachment profile of v. cholerae onto a smooth glass surface. Similar to previous work,footnotetextLauga, E., DiLuzio, W. R., Whitesides, G. M., Stone, H. A. Biophys. J. 90, 400 (2006). we observe right-handed circular swimming trajectories near surfaces; however, in addition we see a host of distinct motility mechanisms that enable rapid exploration of the surface before forming a more permanent attachment. Using isogenic mutants we show that the motility mechanisms observed are due to a complex combination of hydrodynamics and pili-surface interactions.

    Attachment theory provides a framework for understanding individual differences in chronic interpersonal stress. Attachment anxiety, a type of relationship insecurity characterized by worry about rejection and abandonment, is a chronic interpersonal stressor. Stress impacts cellular immunity, including herpesvirus reactivation. We investigated whether attachment anxiety was related to the expression of a latent herpesvirus, Epstein-Barr virus (EBV), when individuals were being tested for breast or colon cancer and approximately 1 year later. Participants (N=183) completed a standard attachment questionnaire and provided blood to assess EBV viral capsid antigen (VCA) IgG antibody titers. Individuals with more attachment anxiety had higher EBV VCA IgG antibody titers than those with less attachment anxiety. The strength of the association between attachment anxiety and antibody titers was the same at both assessments. This study is the first to show an association between latent herpesvirus reactivation and attachment anxiety. Because elevated herpesvirus antibody titers reflect poorer cellular immune system control over the latent virus, these data suggest that high attachment anxiety is associated with cellular immune dysregulation.

    Over the last few days, the Earth has been buffeted by a geomagnetic storm caused by a major solar flare. In addition to disruptions in radio, telecommunications, and electric service, the flare may also produce a dramatic light show as it peaks tonight. Weather permitting, the aurora borealis, or northern lights, may be visible as far south as Washington, D.C. The best viewing time will be local midnight. The sun is currently at the peak of its eleven-year solar cycle, spawning flares and "coronal mass ejections" (CME), violent outbursts of gas from the sun's corona that can carry up to 10 billion tons of electrified gas traveling at speeds as high as 2000 km/s. Geomagnetic storms result when solar winds compress the magnetosphere, sometimes interfering with electric power transmission and satellites, but also creating beautiful aurorae, as many stargazers hope will occur tonight.

  3. Attachment and adolescent depression: the impact of early attachment experiences.

    PubMed

    Shaw, Samantha K; Dallos, Rudi

    2005-12-01

    Bowlby's (1969/1982) ideas of attachment as an interactional system provide the basis for an understanding of the development of adaptive and maladaptive working models of the self and other. More specifically, attachment theory can offer an in-depth understanding into the development of a depressotypic self-schema. Attachment theory is set alongside research into adolescent depression in order to illustrate the importance of the primary attachment relationship in protecting adolescents in our society from developing depressive symptomatology. Therefore, current research in adolescent depression is viewed through the lens of attachment theory. This view is complemented by an exploration of the role of culture in the production of gender differences in depression. Thus, a tripartite model of adolescent depression, including the individual, family relationships, and socio-cultural factors is offered as being of potential value for clinicians and researchers in this area.

    In the second half of the 19th century, Jean-Martin Charcot (1825-1893) became famous for the quality of his teaching and his innovative neurological discoveries, bringing many French and foreign students to Paris. A hunger for recognition, together with progressive and anticlerical ideals, led Charcot to invite writers, journalists, and politicians to his lessons, during which he presented the results of his work on hysteria. These events became public performances, for which physicians and patients were transformed into actors. Major newspapers ran accounts of these consultations, more like theatrical shows in some respects. The resultant enthusiasm prompted other physicians in Paris and throughout France to try and imitate them. We will compare the form and substance of Charcot's lessons with those given by Jules-Bernard Luys (1828-1897), Victor Dumontpallier (1826-1899), Ambroise-Auguste Liébault (1823-1904), Hippolyte Bernheim (1840-1919), Joseph Grasset (1849-1918), and Albert Pitres (1848-1928).

    The ESO Very Large Telescope Interferometer, which allows astronomers to scrutinise objects with a precision equivalent to that of a 130-m telescope, is proving itself an unequalled success every day. One of the latest instruments installed, AMBER, has led to a flurry of scientific results, an anthology of which is being published this week as special features in the research journal Astronomy & Astrophysics. ESO PR Photo 06a/07 ESO PR Photo 06a/07 The AMBER Instrument "With its unique capabilities, the VLT Interferometer (VLTI) has created itself a niche in which it provide answers to many astronomical questions, from the shape of stars, to discs around stars, to the surroundings of the supermassive black holes in active galaxies," says Jorge Melnick (ESO), the VLT Project Scientist. The VLTI has led to 55 scientific papers already and is in fact producing more than half of the interferometric results worldwide. "With the capability of AMBER to combine up to three of the 8.2-m VLT Unit Telescopes, we can really achieve what nobody else can do," added Fabien Malbet, from the LAOG (France) and the AMBER Project Scientist. Eleven articles will appear this week in Astronomy & Astrophysics' special AMBER section. Three of them describe the unique instrument, while the other eight reveal completely new results about the early and late stages in the life of stars. ESO PR Photo 06b/07 ESO PR Photo 06b/07 The Inner Winds of Eta Carinae The first results presented in this issue cover various fields of stellar and circumstellar physics. Two papers deal with very young solar-like stars, offering new information about the geometry of the surrounding discs and associated outflowing winds. Other articles are devoted to the study of hot active stars of particular interest: Alpha Arae, Kappa Canis Majoris, and CPD -57o2874. They provide new, precise information about their rotating gas envelopes. An important new result concerns the enigmatic object Eta Carinae. Using AMBER with its high spatial and spectral resolution, it was possible to zoom into the very heart of this very massive star. In this innermost region, the observations are dominated by the extremely dense stellar wind that totally obscures the underlying central star. The AMBER observations show that this dense stellar wind is not spherically symmetric, but exhibits a clearly elongated structure. Overall, the AMBER observations confirm that the extremely high mass loss of Eta Carinae's massive central star is non-spherical and much stronger along the poles than in the equatorial plane. This is in agreement with theoretical models that predict such an enhanced polar mass-loss in the case of rapidly rotating stars. ESO PR Photo 06c/07 ESO PR Photo 06c/07 RS Ophiuchi in Outburst Several papers from this special feature focus on the later stages in a star's life. One looks at the binary system Gamma 2 Velorum, which contains the closest example of a star known as a Wolf-Rayet. A single AMBER observation allowed the astronomers to separate the spectra of the two components, offering new insights in the modeling of Wolf-Rayet stars, but made it also possible to measure the separation between the two stars. This led to a new determination of the distance of the system, showing that previous estimates were incorrect. The observations also revealed information on the region where the winds from the two stars collide. The famous binary system RS Ophiuchi, an example of a recurrent nova, was observed just 5 days after it was discovered to be in outburst on 12 February 2006, an event that has been expected for 21 years. AMBER was able to detect the extension of the expanding nova emission. These observations show a complex geometry and kinematics, far from the simple interpretation of a spherical fireball in extension. AMBER has detected a high velocity jet probably perpendicular to the orbital plane of the binary system, and allowed a precise and careful study of the wind and the shockwave coming from the nova. The stream of results from the VLTI and AMBER

    Microbial attachment to drinking water pipe surfaces facilitates pathogen survival and deteriorates disinfection performance, directly threatening the safety of drinking water. Notwithstanding that the formation of biofilm has been studied for decades, the underlying mechanisms for the origins of microbial surface attachment in biofilm development in drinking water pipelines remain largely elusive. We combined experimental and mathematical methods to investigate the role of environmental stress-mediated cell motility on microbial surface attachment in chlorination-stressed drinking water distribution systems. Results show that at low levels of disinfectant (0.0-1.0 mg/L), the presence of chlorine promotes initiation of microbial surface attachment, while higher amounts of disinfectant (>1.0 mg/L) inhibit microbial attachment. The proposed mathematical model further demonstrates that chlorination stress (0.0-5.0 mg/L)-mediated microbial cell motility regulates the frequency of cell-wall collision and thereby controls initial microbial surface attachment. The results reveal that transport processes and decay patterns of chlorine in drinking water pipelines regulate microbial cell motility and, thus, control initial surface cell attachment. It provides a mechanistic understanding of microbial attachment shaped by environmental disinfection stress and leads to new insights into microbial safety protocols in water distribution systems.

  11. Stretched View Showing 'Victoria'

    [figure removed for brevity, see original site] Stretched View Showing 'Victoria'

    This pair of images from the panoramic camera on NASA's Mars Exploration Rover Opportunity served as initial confirmation that the two-year-old rover is within sight of 'Victoria Crater,' which it has been approaching for more than a year. Engineers on the rover team were unsure whether Opportunity would make it as far as Victoria, but scientists hoped for the chance to study such a large crater with their roving geologist. Victoria Crater is 800 meters (nearly half a mile) in diameter, about six times wider than 'Endurance Crater,' where Opportunity spent several months in 2004 examining rock layers affected by ancient water.

    When scientists using orbital data calculated that they should be able to detect Victoria's rim in rover images, they scrutinized frames taken in the direction of the crater by the panoramic camera. To positively characterize the subtle horizon profile of the crater and some of the features leading up to it, researchers created a vertically-stretched image (top) from a mosaic of regular frames from the panoramic camera (bottom), taken on Opportunity's 804th Martian day (April 29, 2006).

    The stretched image makes mild nearby dunes look like more threatening peaks, but that is only a result of the exaggerated vertical dimension. This vertical stretch technique was first applied to Viking Lander 2 panoramas by Philip Stooke, of the University of Western Ontario, Canada, to help locate the lander with respect to orbiter images. Vertically stretching the image allows features to be more readily identified by the Mars Exploration Rover science team.

    The bright white dot near the horizon to the right of center (barely visible without labeling or zoom-in) is thought to be a light-toned outcrop on the far wall of the crater, suggesting that the rover can see over the low rim of Victoria. In figure 1, the northeast and southeast rims are labeled in bright green. Finally, the light purple lines and arrow highlight a small crater.

    Models based on preferential attachment have had much success in reproducing the power law degree distributions which seem ubiquitous in both natural and engineered systems. Here, rather than assuming preferential attachment, we give an explanation of how it can arise from a more basic underlying mechanism of competition between opposing forces.

    This research investigated how working models of attachment are carried forward from one relationship to the next. A two-part study was conducted in which participants learned about two potential dating partners: one that was constructed to resemble a romantic partner from their past and one that resembled a partner from another participant's past. Results showed that people applied their attachment representations of past partners to both targets but did so to a greater degree when the target resembled a past partner. People also tended to feel more anxious and less avoidant toward the target that resembled their past partner. Overall, the findings were consistent with the hypothesis that working models of attachment are transferred in both general and selective ways in new relationships. PMID:16513806

    2013-01-01

    Survival of altricial infants depends on attachment to the caregiver – a process that requires infants to identify, learn, remember, and approach their attachment figure. Here we review the neurobiology of attachment in infant rats where learning about the caregiver is supported by a specialized attachment neural circuitry to promote the infant-caregiver relationship. Specifically, the attachment circuit relies on infants acquiring learned preferences to the maternal odor, and this behavior is supported by the hyper-functioning locus coeruleus and generous amounts of norepinephrine to produce experience-induced changes in the olfactory bulb and anterior piriform cortex. Infants also possess a reduced ability to acquire learned aversions or fear, and this behavior is facilitated through attenuated amygdala plasticity to block fear learning. Presumably, this attachment circuitry constrains the infant animal to express only learned preferences regardless of the quality of care received. As pups mature, and begin to travel in and out of the nest, the specialized attachment learning becomes contextually confined to when pups are with the mother. Thus, when outside the nest, these older pups show learning more typical of adult learning, presumably to prepare for independent life outside the nest. The quality of attachment can alter this circuitry, with early life stress prematurely terminating the pups’ access to the attachment system through premature functional activation of the amygdala. Overall, the attachment circuit appears to have a dual function: keeping pups close to the caregiver but also to shape pups’ behavior to match the environment and define long-term emotion and cognition.

    Monford, Leo G., Jr. (inventor)

    1992-01-01

    An electromagnetic attachment mechanism is disclosed for use as an end effector of a remote manipulator system. A pair of electromagnets, each with a U-shaped magnetic core with a pull-in coil and two holding coils, are mounted by a spring suspension system on a base plate of the mechanism housing with end pole pieces adapted to move through openings in the base plate when the attractive force of the electromagnets is exerted on a strike plate of a grapple fixture affixed to a target object. The pole pieces are spaced by an air gap from the strike plate when the mechanism first contacts the grapple fixture. An individual control circuit and power source is provided for the pull-in coil and one holding coil of each electromagnet. A back-up control circuit connected to the two power sources and a third power source is provided for the remaining holding coils. When energized, the pull-in coils overcome the suspension system and air gap and are automatically de-energized when the pole pieces move to grapple and impose a preload force across the grapple interface. A battery backup is a redundant power source for each electromagnet in each individual control circuit and is automatically connected upon failure of the primary source. A centerline mounted camera and video monitor are used in cooperation with a target pattern on the reflective surface of the strike plate to effect targeting and alignment.

    Amino functionalized multi wall carbon nanotubes (MWNT) were reacted with an inorganic Ruthenium complex, {[Ru(dcclbpy)(bpy)2](PF6)2}, in an attempt to covalently attach the Ruthenium complex to the MWNT. The covalent attachment between the Ruthenium complex and the carbon nanotubes is achieved by the formation of an amide group. Absorption and emission spectroscopy indicated that a reaction between the amino functionalized MWNT and the Ruthenium complex occurred. Atomic fore microscopy (AFM) images gave further evidence of a successful attachment of the Ruthenium complex to MWNT by showing multiple junctions between MWNT distinct from naturally occurring splitting of MWNT ropes.

    A hot melt adhesive attachment pad for releasably securing distinct elements together is described which is particularly useful in the construction industry or a spatial vacuum environment. The attachment pad consists primarily of a cloth selectively impregnated with a charge of hot melt adhesive, a thermo-foil heater, and a thermo-cooler. These components are securely mounted in a mounting assembly. In operation, the operator activates the heating cycle transforming the hot melt adhesive to a substantially liquid state, positions the pad against the attachment surface, and activates the cooling cycle solidifying the adhesive and forming a strong, releasable bond.

    The overall aim of the present study was to investigate ADHD symptoms in relation to attachment representations. We used both attachment- and non-attachment-related story stems, which allowed us to investigate whether problems with narrative production can explain the relation between ADHD symptoms and attachment representations. We also investigated the role of cognitive deficits and conduct problems in these relations. The sample consisted of 89 children (27 % girls) between 6 and 10 years old, with an oversampling of children with high levels of ADHD symptoms. ADHD symptoms and conduct problems were rated by parents and teachers. Cognitive functioning was investigated using laboratory tests of inhibition, working memory and sustained attention. Attachment representations were coded as secure, organized insecure and disorganized categories. Narrative responses to non-attachment-related story stems were coded for incoherence and negative content. Results showed that children in the disorganized attachment category had significantly higher levels of ADHD symptoms compared to those in the secure category. Both ADHD symptoms and disorganized attachment were related to incoherence and negative content. Attachment representations were not associated with ADHD symptoms when controlling for negative content in response to non-attachment-related story stems. These results suggest that the associations between attachment security and ADHD are yet to be fully understood. Importantly, a propensity to envisage negative events seems to characterize children with high levels of ADHD symptoms. PMID:24562639

    This paper examines the relations between self-reported attachment orientation at work and personality, self-esteem, trait emotional intelligence (aka emotional self-efficacy), and independently assessed career potential and job performance. Self-report data were collected from 211 managers in an international business in the hospitality industry; independent assessments of these managers' job performance and career potential were separately obtained from the organization. A self-report measure of romantic attachment was adapted for application in the work context; a two-factor solution was found for this measure. Secure/autonomous attachment orientation at work was positively related to self-esteem, trait emotional intelligence, extraversion, agreeableness, and conscientiousness, and also to job performance. Not only was secure/autonomous attachment orientation at work statistically predictive of job performance, but the new measure also made a distinct contribution, beyond conscientiousness, to this prediction.

    Past research shows that attachment security is linked to low prejudice (Hofstra, Van Oudenhoven & Bunnk, 2005; Mikulincer & Shaver, 2001). We extend this research by examining the role of attachment security in discriminatory choices and discriminatory behaviour. The current study examines the influence of primed attachment security (vs. neutral prime) on self-reported discrimination and actual discriminatory behaviour towards Muslims. Results illustrate that primed attachment security (vs. a neutral prime) significantly predicts both the choice to discriminate against Muslims and subsequent behavioural discrimination towards a Muslim. Implications for increasing attachment security as a means of reducing prejudice and discrimination are discussed. PMID:21950402

    We obtain the degree distribution for a class of growing network models on flat and curved spaces. These models evolve by preferential attachment weighted by a function of the distance between nodes. The degree distribution of these models is similar to that of the fitness model of Bianconi and Barabási, with a fitness distribution dependent on the metric and the density of nodes. We show that curvature singularities in these spaces can give rise to asymptotic Bose-Einstein condensation, but transient condensation can be observed also in smooth hyperbolic spaces with strong curvature. We provide numerical results for spaces of constant curvature (sphere, flat, and hyperbolic space) and we discuss the conditions for the breakdown of this approach and the critical points of the transition to distance-dominated attachment. Finally, we discuss the distribution of link lengths.

    2013-12-01

    The degree to which parent sensitivity and infant temperament distinguish attachment classification was examined. Multilevel modeling was used to assess the effect of parent sensitivity and infant temperament on infant-mother and infant-father attachment. Data were collected from mothers, fathers, and their infants (N = 135) when the infant was 3-, 5-, 7-, 12-, and 14-months old. Temperament was measured using the Infant Behavior Questionnaire-Revised (Gartstein & Rothbart, 2003); parent sensitivity was coded during the Still Face Paradigm (Tronick, Als, Adamson, Wise, & Brazelton, 1978); attachment was coded using the Strange Situation (Ainsworth, Blehar, Waters, & Wall, 1978). Results indicate that mothers and fathers were less sensitive with insecure-avoidant infants. Whereas only one difference was found for infant-mother attachment groups and temperament, five significant differences emerged for infant-father attachment groups, with the majority involving insecure-ambivalent attachment. Infants classified as ambivalent with fathers were higher in perceptual sensitivity and cuddliness and these infants also showed a greater increase in low-intensity pleasure over time compared with other infants. Results indicate the importance of both parent sensitivity and infant temperament, though operating in somewhat different ways, in the development of the infant-mother and infant-father attachment relationship.

    2012-04-01

    The aim of the present study was to investigate whether attachment insecurity, focusing on disorganized attachment, and the executive function (EF) component of inhibition, assessed at age 5, were longitudinally related to general externalizing problem behaviors as well as to specific symptoms of ADHD and Autism spectrum disorder (ASD), and callous-unemotional (CU) traits. General externalizing problem behaviors were also measured at age 5 to allow for a developmental analysis. Outcome variables were rated by parents and teachers. The sample consisted of 65 children with an oversampling of children with high levels of externalizing behaviors. Attachment was evaluated using a story stem attachment doll play procedure. Inhibition was measured using four different tasks. The results showed that both disorganized attachment and poor inhibition were longitudinally related to all outcome variables. Controlling for initial level of externalizing problem behavior, poor inhibition predicted ADHD symptoms and externalizing problem behaviors, independent of disorganized attachment, whereas for ASD symptoms no predictive relations remained. Disorganized attachment independently predicted CU traits. PMID:21947617

    The aim of the present study was to examine differences in anxiety and depression related to differences in attachment models of the self and of others and whether personality traits mediate this relationship. The authors assessed attachment styles, anxiety, depression, and personality traits among 274 adult volunteers. Participants were classified into 4 attachment groups (secure, preoccupied, fearful, and dismissing-avoidant) according to K. Bartholomew's (1990) model. The present authors found significant differences among attachment groups on anxiety and depressive symptoms with attachment styles involving a negative self-model showing higher scores than attachment styles characterized by a positive self-model. The authors also found that differences between attachment styles in anxiety and depression remained significant when personality factors related to attachment prototypes were entered as covariates. Results indicate that secure attachment in adults was associated with better mental health, while insecure attachment styles characterized by negative thinking about the self were associated with higher depression and anxiety scores. Our findings seem to evidence that attachment and personality are only partly overlapping and that attachment cannot be considered as redundant with personality in the explanation of psychological disease.

    This study explores the relative contribution of the overall quality of attachment to the mother, to the father and to peers (Inventory of Parent and Peer Attachment scales), the style of attachment towards peers (Attachment Questionnaire for Children scale), the social rank variables (submissive behavior and social comparison), and sex and age variables in predicting the depression score (Center of Epidemiological Studies Depression Scale) on a non-psychiatric sample of 13-18 year old adolescents (n = 225). Results of our integrated model (adjusted R-Square of .50) show that attachment variables (overall quality of attachment to the father and to the mother), social rank variables (social comparison and submissive behavior), age and sex are important in predicting depressive symptoms during adolescence. Moreover, the attachment to peers variables (quality of attachment to peers, secure and ambivalent style of attachment) and sex are mediated by the social rank variables (social comparison and submissive behavior).

    The present study explored the role of attachment insecurity in cervical screening behaviors and barriers in a sample of 257 female undergraduates. Information on attachment dimensions as well as attachment style was collected. Attachment anxiety and attachment avoidance were associated with decreased likelihood of having participated in cervical screening and positively associated with screening barriers. Screening barriers were elevated among individuals with insecure attachment styles (preoccupied, fearful, and dismissing), and dismissing participants were less likely to have engaged in screening compared to secure participants. Our findings demonstrate that attachment insecurity may be a risk factor for inadequate cervical screening and screening barriers. PMID:22933580

    The potential of microalgae biofuel has not been realized because of low productivity and high costs associated with the current cultivation systems. In this paper, an attached cultivation method was introduced, in which microalgae cells grew on the surface of vertical artificial supporting material to form algal film. Multiple of the algal films were assembled in an array fashion to dilute solar irradiation to facilitate high photosynthetic efficiency. Results showed that a broad range of microalgae species can grow with this attached method. A biomass productivity of 50-80 g m(-2) d(-1) was obtained outdoors for Scenedesmus obliquus, corresponding to the photosynthetic efficiency of 5.2-8.3% (total solar radiation). This attached method also offers lots of possible advantages over traditional open ponds, such as on water saving, harvesting, contamination controlling and scale-up. The attached cultivation represents a promising technology for economically viable production of microalgae biofuels. PMID:23131644

  3. Aspects of love: the effect of mortality salience and attachment style on romantic beliefs.

    PubMed

    Smith, Rebecca; Massey, Emma

    Two studies are reported which explore romance as a means of terror management for participants with secure and insecure attachment styles. Mikulincer and Florian (2000) have shown that while mortality salience increases the desire for intimacy in securely attached individuals, the insecurely attached use cultural world views rather than close relationships to cope with fear of death. Study 1 used the romantic belief scale to compare the effects of attachment style and mortality salience on the cultural aspects of close relationships and showed that the only the insecurely attached were more romantic following mortality salience. Study 2 replicated this effect and demonstrated that this difference was not simply due to lower self-esteem in the insecurely attached. The additional inclusion of the Relationship assessment questionnaire failed to provide any evidence that the securely attached were affected by the mortality salience manipulation, even on a more interpersonal measure.

    The objective of this article is to fully understand Internet addiction, we aimed to compare the attachment styles and psychopathologies associated with problematic Internet use with those related to alcohol use. Through the participation of 141 male participants, the present study assessed problematic Internet and alcohol use, attachment, psychopathology, and demographic data via the use of self-rating questionnaires. We explored the significant predictors among avoidant and anxious attachments, depression, anxiety, and phobia to explain problematic Internet and alcohol use. The results showed that anxious attachment, depression, and anxiety could explain problematic alcohol use. In contrast, both anxious and avoidant attachment as well as depression and phobia explained problematic Internet use. Additionally, depression moderated the effects of avoidant attachment on problematic Internet use. We demonstrated that the interaction of attachment and psychopathology predicts problematic Internet use originating from an earlier stage of life than that associated with problematic alcohol use.

    The intense, unstable interpersonal relationships characteristic of patients with borderline personality disorder (BPD) are thought to represent insecure attachment. The Reciprocal Attachment Questionnaire was used to compare the attachment styles of patients with BPD to the styles of patients with a contrasting personality disorder, obsessive-compulsive personality disorder (OCPD). The results showed that patients with BPD were more likely to exhibit angry withdrawal and compulsive care-seeking attachment patterns. Patients with BPD also scored higher on the dimensions of lack of availability of the attachment figure, feared loss of the attachment figure, lack of use of the attachment figure, and separation protest. The findings may be relevant for understanding the core interpersonal psychopathology of BPD and for managing therapeutic relationships with these patients. PMID:16397756

    Young children who have experienced early adversity are at risk for developing disorganized attachments. An intervention, Attachment and Biobehavioral Catch-up (ABC), was developed that very specifically targets nurturing, sensitive care among the parents identified as being at risk for neglecting their young children, with the aim of decreasing disorganized attachment. The ABC intervention consists of 10 parent-child sessions conducted in families’ homes. The present study assessed the efficacy of this intervention through a randomized clinical trial in which parents with Child Protective Services involvement were assigned to the experimental intervention or to a control intervention (DEF). Attachment quality was assessed for 120 children in the Strange Situation. Children in the ABC intervention showed significantly lower rates of disorganized attachment (32%) and higher rates of secure attachment (52%) relative to the control intervention (57% and 33%, respectively). These results support the efficacy of the ABC intervention in enhancing attachment quality among parents at high risk for maltreatment. PMID:22239483

  7. Dissociative electron attachment to water

    Haxton, Daniel James

    Dissociative electron attachment to water, H2O+e-? H+OH-3.27eV H2+O-3.56eV H-+OHX P2 4.35eVH+H+O-8.04e VH-+OH* S2 8.38eVH-+H+O 8.75eV 0.1 is a physical process that has been studied since 1930[1]. It may be viewed as an inherently is non-Born-Oppenheimer process, for the initial state belongs to the electronic continuum, and the final state is electronically bound. As such, it presents a particular challenge for theory. We present a first-principles theoretical treatment of this process, in which we calculate the cross sections for production of the three major atom - diatom products observed by experiment, H2 + O-, H- + OH (X 2pi), and H- + OH (2Sigma). These states comprise the bulk of the experimentally determined cross section. In the present work we employ a Born-Oppenheimer expansion of the wavefunction for nuclear and electronic motion, and treat both quantum mechanically. The adiabatic treatment of the electronic motion incorporates multiconfiguration, correlated wavefunctions and includes an explicit treatment of the electronic continuum. For the nuclear dynamics we incorporate the full dimensionality of nuclear motion, including the three internal degrees of freedom and the effect of rotation. This is the first ab initio treatment of dissociative electron attachment which incorporates more than one degree of freedom in the nuclear dynamics. The first step in our Born-Oppenheimer treatment is to calculate adiabatic potential energy surfaces for the three metastable electronic states which are involved, the 2B1, 2A1, and 2B 2 electronic Feshbach resonances. Global potential energy surfaces are defined which incorporate the results of fixed-nuclei, ab initio calculations: quantum-mechanical electron scattering calculations using the complex Kohn method are performed and augmented by the results of large-scale configuration-interaction calculations performed in a restricted Hilbert space. The global surfaces are defined by a very accurate fit combining a 35-parameter analytic function and splines. The second step in our treatment comprises the use of these potential energy surfaces to calculate the nuclear dynamics. We do so within the Local Complex Potential model, a theory which has had considerable success in describing both vibrational excitation and dissociative electron attachment in resonant electron-molecule collisions. Its applicability to the current system is, however, not assured, and we offer evidence that the experimental observations, and in particular the results on the minor arrangement channels observed at each resonance peak, may rest upon nonlocal or virtual-state effects during the dissociation. We employ the Multi-Configuration Time-Dependent Hartree method to calculate the nuclear dynamics. These dynamics, even within the Local Complex Potential model, are subject to nonadiabatic coupling among these surfaces, due to Renner-Teller coupling between the 2B1 and 2 A1, and a conical intersection between the 2 A1 and 2B2. We include these nonadiabatic effects in our treatment. The conical intersection is calculated to play a major role for dissociative attachment to water via the highest-energy, 2B2 Feshbach resonance, as we have predicted. The bulk of the present work is concerned with the calculation of the total cross sections for DEA via each of the resonance states. In the final chapter of this work, we include the results of separate calculations which examine the differential cross section for production of H- via the 2B1 resonance. We derive a new approximation, which we term the "single-eigenmode" approximation for resonant scattering, and employ it to calculate the angular distribution of the H- fragment. We reproduce the experimental result. We show how the single-eigenmode approximation breaks down in the case of hydrogen sulfide, H2S, and reproduce the previously unexplained experimental result for the angular distribution of H- ions produced from DEA to the 2B1 state of H 2S.

  8. Telephoto attachments for telecentric lenses

    NASA Astrophysics Data System (ADS)

    Weiner, David

    1995-08-01

    Many imaging applications, such as machine vision, parts inspection, and gauging, make us of telecentric lens configurations to improve measurement accuracy and reduce alignment sensitivity. CCD cameras are frequently chosen to record the final image. Although lenses can be designed to work as standalone telecentric devices, it is sometimes desireable to use a modular approach, in which a telecentric `attachment' is mated to a primary or `base' lens. This allows one to vary the object field coverage by changing attachment lenses, keeping the same primary lens. A simple attachment could consist of an achromat mounted one focal length away from the entrance pupil of the primary lens. Such arrangements can become lengthy for large fields and magnifications. Stock achromats may not meet size requirements, nor provide optimum image quality. A more complex arrangement that reduces the lens length and improves imaging can be obtained by using a telephoto lens (front-vertex-to-image/efl < 1.0) as an attachment. This paper will outline the development of a modular telecentric system and a first-order method for evaluating the suitability of lenses for use as telecentric attachments.

    2015-02-01

    Although empathy has been associated with helping behavior and relationship quality, little research has evaluated the role of parental empathy in the development of parent-child relationships. The current study (1) establishes preliminary validity of the Parental Affective and Cognitive Empathy Scale (PACES), a method for coding empathy from parents' narrative responses to the Parent Development Interview - Revised for School-Aged Children (PDI-R-SC), and (2) tests a theoretical model of empathy and attachment. Sixty caregivers and their children completed a battery of questionnaire and interview measures, including the PDI-R-SC and the Child Attachment Interview (CAI). Caregivers' interview narratives were scored for empathy using PACES. PACES showed good interrater reliability and good convergent validity with a self-report empathy measure. Parent empathy was positively related to child attachment security (using a continuous score for narrative coherence) and emotional openness on the CAI, as well as to child perceptions of parental warmth. Moreover, parent empathy mediated the relation between parents' self-reported attachment style and their children's attachment security. Implications for attachment theory and future directions for establishing scale validity are discussed. PMID:25373381

    This study explored the degree to which adult patients with Tourette syndrome (TS) exhibit particular attachment styles and the possible association between the underlying attachment dimensions and forms of aggression. Fifty-three TS patients (ages 17-72 years) and 54 matched healthy controls completed the Experiences in Close Relationships-Revised Scale (ECR-R) and the Aggression Questionnaire (AQ). The data were analysed with ANOVA F-tests, t-tests, and Pearson's correlation coefficient. TS patients showed significantly higher scores in relationship anxiety (?p < 0.001) and relationship avoidance (?p = 0.001) in the ECR-R and significantly higher aggression scores in the AQ (?p < 0.001). The total AQ score correlated significantly with the ECR-R dimension anxiety (?p < 0.001). These are the first findings on TS patients' attachment styles and anger symptoms. It remains unclear whether attachment anxiety and avoidance are risk factors for TS or whether the disorder itself induces attachment disorders. Prospective studies with detailed attachment interviews would help to explore this issue. PMID:25185020

    Thirteen-month-old maltreated infants (n = 137) and their mothers were randomly assigned to one of three conditions: child-parent psychotherapy (CPP), psychoeducational parenting intervention (PPI), or community standard (CS). A fourth group of nonmaltreated infants (n = 52) and their mothers served as a nonmaltreated comparison (NC) group. A prior investigation found that the CPP and the PPI groups demonstrated substantial increases in secure attachment at postintervention, whereas this change was not found in the CS and the NC groups. The current investigation involved the analysis of data obtained at a follow-up assessment that occurred 12 months after the completion of treatment. At follow-up, children in the CPP group had higher rates of secure and lower rates of disorganized attachment than did children in the PPI or the CS group. Rates of disorganized attachment did not differ between the CPP and the NC groups. Intention to treat analyses also showed higher rates of secure attachment at follow-up in the CPP group relative to the PPI and the CS groups. However, groups did not differ on disorganized attachment. Both primary and intention to treat analyses demonstrated that maternal-reported child behavior problems did not differ among the four groups at the follow-up assessment. This is the first investigation to demonstrate sustained attachment security in maltreated children 12 months after the completion of an attachment theory informed intervention. The findings also suggest that, although effective in the short term, parenting interventions alone may not be effective in maintaining secure attachment in children over time. PMID:24229539

  15. Enhanced electron attachment to vibrationally and electronically excited molecules

    NASA Astrophysics Data System (ADS)

    Tav, Cumali

    Electron attachment studies on vibrationally and electronically excited states have been measured. The attachment of electrons to vibrationally excited states of the ground electronic state populated via temperature increase was measured in the mean electron energy range, (?), 0.04 to 4.8 eV, over the temperature range, T, 300 to 700 K and over the total gas number density, Nt, 2.25 to 15.5 × 1019 molecules/cm3. These studies are presented in Part 1 for three technologically important molecules: Methylene Chloride (C2H2Cl2), Boron Trichloride (BCl3), and Trichlorotrifluoroethane (1,1,2-C 2Cl3F3). Electron attachment rate constants, k a((?),T), was measured as a function of mean electron energy in Ar and N2 gases at different temperatures. Using swarm unfolding technique, electron attachment cross sections, ?a(?,T), was measured as a function of electron energy by unfolding ka((?),T) at each temperature. The results of these measurements show that the dissociative electron attachment cross sections increase with the increase of vibrational energies. In the studies an electronically-excited states, the attaching electrons and the excited states of molecules were produced with a single excimer-laser pulse. The excitation of molecules to energies above the ionization potential (IP) caused the population of core-excited Rydberg states (HR). The electrons produced via photoionization were attached to the concomitantly produced highly-excited molecules leading to negative ion formation under the high-pressure environment provided by Ar or N2 gases. In these experiments two different experimental techniques were used: two- electrode arrangement and three-electrode arrangement. The two-electrode arrangement techniques provided information on the lifetimes of the excited molecules as well as estimates of various experimental parameters including the electron attachment rate constant of excited molecules. The other technique, the three- electrode arrangement, provided information about the density of charged species including electrons and negative ions and the estimation of electron attachment rate constant. These results are presented in Part II for three molecules: Benzene (C6H 6), Oxygen (O2), and Dichlorodifluoromethane (CCl2,F2). It was shown that the electron attachment to highly-excited molecules was extremely efficient process leading to enormous electron attachment cross sections, ?a, ~ 10-10 cm2, which were many orders of magnitude larger compared to the cross sections for corresponding ground electronic states.

    This study examined the mediating role of ego defense mechanisms on the relationship between attachment styles and alexithymia. Four hundred and forty-three Iranian high school students (213 boys, 230 girls) participated in this study. Participants completed Defense Styles Questionnaire (DSQ-40), Adult Attachment Inventory (AAI), and Farsi version of the Toronto Alexithymia Scale (FTAS-20). Results showed a significant negative correlation between secure attachment style and alexithymia, while avoidant and ambivalent attachment styles showed significant positive associations with alexithymia. Regression analysis indicated that defense mechanisms have a mediating role between attachment styles and alexithymia. It can be concluded that a mediation role of ego defense mechanisms on the relationship between attachment styles and alexithymia was partial. PMID:24309875

    Following an acrimonious divorce or separation, arguments are frequently presented as to why a child should not be with a nonresident parent. The custodial parent, whether a father or a mother, uses the concept of a child being attached to himself or herself and therefore this should prevent the child from having actual or reasonable contact with the absent parent.

    Insecurely attached people have less happy, unstable romantic relationships, but the quality of their relationships should depend on how their partners regulate them. Some partners find ways to buffer (emotionally and behaviorally regulate) insecurely attached individuals, which makes them feel better, behave more constructively, and improves their relationships. Understanding when and how this important interpersonal process works requires a dyad-centered approach. In this article, we describe core tenets of attachment theory and the two forms of attachment insecurity (anxiety and avoidance). We then present the Dyadic Regulation Model of Insecurity Buffering, which explains how and why certain types of buffering behaviors soothe the worries and improve the relationship perceptions and behaviors of anxious or avoidant people. We next review studies of couples trying to resolve major conflicts that illustrate some ways in which partners can successfully buffer the insecure reactions of anxious and avoidant individuals. We conclude by discussing other traits and social contexts to which our model can be applied. PMID:25214722

    Background In recent years, great attention has been given to the presence of psychological problems and psychiatric comorbidity that are also present in children affected by primary headaches. The relationship between pain and attachment has been identified, and it may be that pain perception may change in relation with specific attachment styles. The aim of the present study was to assess the prevalent attachment style and verify its putative relationship and correlation with the main characteristics of migraine attacks, in school-aged children affected by migraine without aura (MoA). Materials and methods The study population consisted of 219 children (103 males, 116 females) aged between 6 and 11 years (mean 8.96 ± 2.14 years), consecutively referred for MoA compared with 381 healthy controls (174 males, 207 females; mean age 9.01 ± 1.75 years) randomly selected from schools. All the children were classified according to the attachment typologies of the Italian modified version of the Separation Anxiety Test; monthly headache frequency and mean headache duration were assessed from daily headache diaries kept by all the children. Headache intensity was assessed on a visual analog scale. The chi-square test and t-test, where appropriate, were applied, and the Spearman rank correlation test was applied to explore the relationship between the types of attachment style and clinical aspects of MoA. Results The MoA group showed a significantly higher prevalence of type A (avoidant) attachment (P<0.001) and a significantly lower prevalence of type B (secure) attachment (P<0.001) compared with the control group. Moreover, the Spearman rank correlation analysis showed a significant relationship between MoA characteristics and the attachment style of MoA children. Conclusion The main findings of the present study were the higher prevalence among MoA children of the avoidant attachment style (type A) and the significantly lower prevalence of the secure style attachment (type B) compared with the normal controls, suggesting that the study of psychiatric comorbidity in pediatric headache may be enriched by this new aspect of analysis.

    Background and aims Sexual addiction, also known as hypersexual disorder, is associated with serious psychosocial problems for many people. Methods This study used questionnaires to investigate the effects of gender, sexual orientation and attachment (avoidance and anxiety) on sexual compulsion among 100 heterosexual and homosexual men and women. Results A positive correlation was found between anxious attachment and sexual compulsivity (r = 0.46; p < 0.01) and a positive correlation between avoidant attachment and sexual compulsivity (r = 0.39; p ? 0.01) in all participants. Secondly, an analysis of covariance showed a gender by sexual orientation interaction effect [F(1, 103) = 6.39, p < 0.01] but no attachment effect on sexual compulsivity. A follow-up comparison showed that lesbian women had higher rates of sexual compulsivity than heterosexual women [t (2, 50) = 5.08, p < 0.001] whereas there was non-significant difference in sexual compulsivity between homosexual and heterosexual men [t (2, 50) = 1.30, p = N.S.]. Discussion The results provide preliminary evidence for an association between attachment and sexual compulsivity and the effects of gender and sexual orientation on sexual compulsivity.

    Attachment theory predicts and subsequent empirical research has amply demonstrated that individual variations in patterns of early attachment behaviour are primarily influenced by differences in sensitive responsiveness of caregivers. However, meta-analyses have shown that parenting behaviour accounts for about one third of the variance in attachment security or disorganisation. The exclusively environmental explanation has been challenged by results demonstrating some,

    2015-01-01

    In recent years research on physiological response and frontal electroencephalographic (EEG) asymmetry in different patterns of infant and adult attachment has increased. We review research findings regarding associations between attachment classifications and frontal EEG asymmetry, the autonomic nervous system (ANS) and the hypothalamic-pituitary-adrenocortical axis (HPA). Studies indicate that insecure attachment is related to a heightened adrenocortical activity, heart rate and skin conductance in response to stress, which is consistent with the hypothesis that attachment insecurity leads to impaired emotion regulation. Research on frontal EEG asymmetry also shows a clear difference in the emotional arousal between the attachment groups evidenced by specific frontal asymmetry changes. Furthermore, we discuss neurophysiological evidence of attachment organization and present up-to-date findings of EEG-research with adults. Based on the overall patterns of results presented in this article we identify some major areas of interest and directions for future research. PMID:25745393

    Background: Fathers’ cooperation has been less taken into account in the process of pregnancy. The present study aimed to investigate the effect of training the fathers regarding attachment skills on maternal-fetal attachment in primigravida women in 2013. Methods: This randomized controlled trial was performed on 150 qualified pregnant women’s husbands. The intervention group took part in four 90-minute sessions of maternal-fetal attachment training held once a week. On the other hand, the control group received the routine pregnancy care. Both groups completed Spielberger’s anxiety scale and Cranley’s questionnaire before and after the intervention. Then, the data were analyzed using paired and independent t-test. Besides, P<0.05 was considered as statistically significant. Results: The intervention group’s mean score of attachment was 55.98±6.99 and 61.90±5.41 before and after the intervention, respectively. The results of paired t-test revealed a significant difference between the intervention and the control group regarding their mean scores of attachment before and one month after the intervention (P<0.001). Additionally, the results of independent t-test showed a significant difference between the two groups regarding the five dimensions of the questionnaire, namely interaction with the baby (P<0.001), acceptance of maternal role (P<0.001), differentiation between oneself and the baby (P<0.001), attribution of some features to the baby (P=0.01), and self-devotion (P=0.01). Conclusion: Training the fathers regarding the attachment behaviors and skills led to an increase in the maternal-fetal attachment scores. Thus, paternal training should be considered in pregnancy care programs. Trial Registration Number: IRCT2012091910886N1 PMID:25349869

    Attachment theorists propose that individuals' internal working models influence their social information processing. This study explored links between attachment representations and social information processing by examining adolescents' (n = 189; Mage  = 16.5 years) attachment-related memory biases. Participants completed laboratory tasks assessing memory for (a) emotionally salient childhood events, (b) adjectives describing their parents, and (c) generalized parent-related characteristics not specific to their own parents. As expected, dismissing attachment (assessed using the Adult Attachment Interview) was linked across tasks to a deactivating strategy in which memory for emotional childhood events and attachment-relevant stimuli was reduced. In contrast, evidence that preoccupied attachment was linked to a hyperactivating strategy in which memory was heightened emerged only in relation to emotional childhood events. PMID:25040922

  5. Adult attachment insecurity and hippocampal cell density

    2010-01-01

    Recent findings associate attachment insecurity (assessed as levels of attachment anxiety and avoidance) with poor emotion regulation. In turn, emotion regulation has been shown to be associated with hippocampus (HC) functioning and structure. Clinical disorders such as depression and PTSD, which have been previously associated with attachment insecurity, are also known to be linked with reduced hippocampal cell density. This suggests that attachment insecurity may also be associated with reduced hippocampal cell density. We examined this hypothesis using T1 images of 22 healthy young adults. In line with our hypothesis, attachment avoidance was associated with bilateral HC reduction, whereas attachment anxiety was significantly related to reduced cell concentration in the left HC. The findings are compatible with a neurotoxical model of stress-induced cell reduction in the HC, providing further information on emotion regulation abilities among insecurely attached individuals.

    In this study, the authors explored the relations among painful experience during sexual intercourse, attachment style, and somatization. The authors assessed these variables by self-report of dyspareunia (painful vaginal intercourse) and by completion of the Experience in Close Relationships Scale and the short version of the Brief Symptom Inventory. The sample included 110 women, 45 of whom reported painful intercourse and were defined as the dyspareunia group, and the remaining 65 were defined as the control group. The dyspareunia group showed greater incidence, compared with the control group, of insecure attachment styles defined by higher scores of anxiety and/or avoidance as well as higher somatization levels. Regression analyses revealed that increased level of somatization and higher level of avoidance predicted higher probability for dyspareunia. The authors' findings suggest that women with higher frequency of physical complaints in various body areas and insecure attachment style are more susceptible to report pain during intercourse.

  7. Enhanced electron attachment to superexcited states of saturated tertiary amines

    Electron attachment measurements on excimer-laser-excited superexcited states (SES) of saturated amine compounds, and in particular on triethylamine (TEA), have been carried out employing a new experimental technique. A rate equation analysis based on a proposed model shows that the electron attachment rate constant for the SES is several orders of magnitude larger than that for the ground electronic state. The proposed mechanism for electron attachment to SES involves the capture of a near-zero-energy electron—(produced by the same laser pulse that produces the SES)—by a superexcited molecule to form a transient parent anion which subsequently dissociates producing a stable fragment anion. The similarity of the above mechanism to an electron-excited Feshbach resonance is indicated and a scheme for the identification of molecular systems that can be excited (via resonance-enhanced multiphoton excitation) to SES is outlined.

    It is increasingly recognized that early sensitive care-giving predicts a secure attachment in infancy and early childhood.This preliminary report details the development, implementation and evaluation of a clinical programme that used a targeted prevention approach following a universally-offered screening of parent-infant interactions. The CARE-Index was used to assign dyads to low, medium and high risk groups, and interventions - featuring reflective videotape-based feedback - were tailored to each risk group in order to increase maternal sensitivity and improve infant attachment status. Results showed improved maternal sensitivity in the intervention conditions compared to comparisons. In addition, infants in the intervention conditions were significantly more likely to be classified as secure, and significantly less likely to be classified as having DMM complex attachment strategies. Methodological shortcomings, however, mean that these findings should be regarded as tentative. PMID:20603424

    This work presents the results of the attachment of Qdot 655 ITKTM amino (PEG) quantum dots (QDs) (Invitrogen) and CdTe QDs (provided by Institute of Materials Science, VAST) to HER2 (Human Epidermal growth factor Receptor 2) specific phage antibodies (Abs) (provided by Institute of Biotechnology, VAST) in solution. The QDs were attached to the phage display specific HER2 Abs to form a complex QD–Ab. The QDs and complex QD–Ab were characterized by UV-VIS spectroscopy, transmission electron microscopy (TEM) and fluorescence microscopy. The fluorescence images show the QDs conjugated to the phage. Due to the QDs attaching to the surface, the phage dimensions were amplified, so its shape could be observed by optical microscopy. The complex QD–Ab was stable and lasted for a month. The results illustrate the value of the HER2 phage–QD complex as a cancer detection platform.

    1991-01-01

    Attachment of Treponema denticola ATCC 35405 to laminin, a major basement membrane protein, and to other proteins was studied. Microdilution plates were coated with the proteins, and the attachment of T. denticola was measured by the enzyme-linked immunosorbent assay technique. Compared with bovine serum albumin (BSA), T. denticola had a high affinity to laminin, fibronectin, fibrinogen, and gelatin, as well as to type I and type IV collagens. Attachment to RGD peptide (Gly-Arg-Gly-Asp-Ser, the integrin recognition sequence) was only about 30% of that to laminin and was comparable to attachment to BSA. Tests with laminin fragments obtained through elastase digestion showed that the spirochetes attached well to an A-chain 140-kDa fragment involved in eukaryote cell attachment but did not attach to a 50-kDa fragment that includes the heparin binding site. Pretreatment of T. denticola with soluble laminin, fibronectin, gelatin, BSA, or fibrinogen had no effect on the attachment of the bacteria to laminin or fibronectin. A wide variety of compounds were tested for their possible inhibitory actions on the attachment. While most treatments of T. denticola ATCC 35405 had little or no effect on the attachment to proteins, sulfhydryl reagents p-chloromercuribenzoic acid (pCMBA) and oxidized glutathione inhibited the attachment by 70 to 99%, depending on the protein. When T. denticola was first allowed to attach to proteins, addition of pCMBA or oxidized glutathione could no longer reverse the attachment. Heat treatment of the spirochetes also markedly reduced the attachment to laminin, gelatin, and fibrinogen but not to BSA. Mixed glycosidase treatment of the spirochetes inhibited the attachment by 20 to 80%. None of the above treatments of the substrate proteins had any marked effect on the spirochete attachment. The results indicate that T. denticola has the capacity to bind to many different kinds of proteins by utilizing specific attachment mechanisms. The binding appears to involve protein SH groups and/or carbohydrate residues on the surface of T. denticola. Images PMID:1937780

    Electron attachment to trichlorotrifluoroethane (1, 1, 2-0022-3727/30/18/015/img10) was investigated in buffer gases of 0022-3727/30/18/015/img11 and Ar using a high-temperature electron swarm apparatus. The negative ion intensity was also measured as a function of electron energy using an electron beam apparatus. The electron attachment rate constant, 0022-3727/30/18/015/img12, was measured in the mean electron energy range, 0022-3727/30/18/015/img13, 0.043 to 4.7 eV and over a temperature, T, range 300 to 700 K in the electron swarm experiments. The electron attachment rate constant was found to first increase slightly with increasing temperature and subsequently decrease for 0022-3727/30/18/015/img14 K. Our room-temperature electron beam study showed that 1, 1, 2-0022-3727/30/18/015/img10 attaches electrons predominantly via dissociative negative ion states and revealed that the electron attachment cross section exhibits three main peaks: one at 0022-3727/30/18/015/img16 eV producing 0022-3727/30/18/015/img17, a second one at 0022-3727/30/18/015/img18 eV due to 0022-3727/30/18/015/img19 and a third one at 0022-3727/30/18/015/img20 eV also producing 0022-3727/30/18/015/img19. The electron attachment cross sections obtained using an electron swarm-unfolding technique show that the peak at 0022-3727/30/18/015/img16 eV observed in the electron beam study is actually composed of three peaks; one at 0022-3727/30/18/015/img16 eV and two more at higher electron energies but below 1.5 eV.

    An interpersonal model of Binge Eating Disorder (BED) posits that difficulties with social functioning precipitate negative affect, which in turn causes binge eating as a means of coping. Thus, long-term decreases in attachment insecurity may be important for women with BED. No research has assessed if long-term change in attachment insecurity is associated with sustained change in other outcomes. In the current study, we hypothesized that changes in attachment anxiety and avoidance will decrease at posttreatment and will be maintained up to 12 months after Group Psychodynamic Interpersonal Psychotherapy (GPIP). We further hypothesized that long-term stability of these changes in attachment insecurity will be related to other long-term outcomes. Women with BED (N = 102) attended 16 sessions of GPIP. Measures were completed pretreatment, posttreatment, at 6 and 12 months follow-up. Attachment anxiety, attachment avoidance, and the other outcome variables decreased significantly at 12 months posttreatment. Reductions in attachment anxiety and avoidance were significantly related to decreases in interpersonal problems up to 12 months posttreatment, and reduction in attachment anxiety was significantly related to decreases in depressive symptoms 12 months posttreatment. Further, the significant relationship between reduced attachment avoidance and decreased interpersonal problems strengthened over the long term. This is the first study to show an association between change in attachment insecurity and change in other outcomes in the long term, and to show an adaptive spiral in which greater reduction in attachment avoidance is increasingly associated with ongoing improvement of interpersonal problems.

    Research on antecedents of organized attachment has focused on the quality of caregiving received during childhood. In recent years, research has begun to examine the influence of genetic factors on quality of infant attachment. However, no published studies report on the association between specific genetic factors and adult attachment. This study examined the link between the 5-HTTLPR promoter polymorphism of the serotonin transporter gene and adult unresolved attachment assessed with the Adult Attachment Interview. Genetic material and information on attachment-related loss or trauma were available for 86 participants. Multivariate regression analyses showed an association between the short 5-HTTLPR allele and increased risk for unresolved attachment. Temperament traits and psychological symptoms did not affect the association between 5-HTTLPR and unresolved attachment. The authors hypothesize that the increased susceptibility to unresolved attachment among carriers of the short allele of 5-HTTLPR is consistent with the role of serotonin in modulation of frontal–amygdala circuitry. The findings challenge current thinking by demonstrating significant genetic influences on a phenomenon previously thought to be largely environmentally driven. PMID:19209991

    2012-01-01

    This pilot study examined the effect of five child and maternal factors on the attachment security of international adoptees at six months post adoption. Results from the sample of 22 adoptive mother-infant dyads showed that age at adoption, developmental status, length and quality of preadoption care, and maternal attachment representations were not significant predictors of child attachment status. The number of preadoption placements and the child's stress level did significantly predict attachment status, accounting for approximately 40% of the variance in attachment security. Number of preadoption placements uniquely contributed 14% of that variance (p=.007) while stress level uniquely contributed 12% (p=.01). Children who had fewer preadoption placements had higher attachment security; similarly, children who had lower stress levels had higher attachment security. Results suggest that consistency of preadoption care was more important than its length or quality. Further, the relationship between stress level and attachment security raises the possibility that a lower stress level functions as a protective factor for the developing attachment with the adoptive mother.

    When people encounter threats, their attachment systems are activated and they become motivated to seek protection and support through proximity to their attachment figures. Theoretically, therefore, mental representations of attachment figures should be associated with goals related to attaining proximity and safety. The present studies explore this idea by examining the effects of a person’s chronic attachment style and exposure to a particular attachment figure’s name on the automatic activation of attachment-related goals. Studies 1 and 2 examine effects of exposure to the name of a security-providing attachment figure on willingness to self-disclose and seek support (two behaviors related to gaining proximity). Study 3 examines how exposure to names of different relationship partners (with whom a participant has felt secure, anxious, or avoidant) affects the mental accessibility of attachment-related goal words. Taken together, the studies support the idea that mental representations of attachment figures are associated with attachment-related goals. PMID:16963608

    2010-06-01

    We examined whether accuracy of affective forecasting for significant life events was moderated by a theoretically relevant individual difference (anxious attachment), with different expected relations to predicted and actual happiness. In 3 studies (2 cross-sectional, 1 longitudinal), participants predicted what their happiness would be after entering or ending a romantic relationship. Consistent with previous research, people were generally inaccurate forecasters. However, inaccuracy for entering a relationship was significantly moderated by anxious attachment. Predictions were largely unrelated to anxious attachment, but actual happiness was negatively related to attachment anxiety. Moderation for breaking up showed a similar but less consistent pattern. These results suggest a failure to account for one's degree of anxious attachment when making affective forecasts and show how affective forecasting accuracy in important life domains may be moderated by a focally relevant individual difference, with systematically different associations between predicted and actual happiness.

    2002-01-01

    Microscopic beads or other structures are attached to nucleic acids (DNA) using a terminal transferase. The transferase adds labeled dideoxy nucleotide bases to the ends of linear strands of DNA. The labels, such as the antigens digoxigenin and biotin, bind to the antibody compounds or other appropriate complementary ligands, which are bound to the microscopic beads or other support structures. The method does not require the synthesis of a synthetic oligonucleotide probe. The method can be used to tag or label DNA even when the DNA has an unknown sequence, has blunt ends, or is a very large fragment (e.g., >500 kilobase pairs).

    We propose a preferential attachment model for network growth where new entering nodes have a partial information about the state of the network. Our main result is that the presence of bounded information modifies the degree distribution by introducing an exponential tail, while it preserves a power law behaviour over a finite small range of degrees. On the other hand, unbounded information is sufficient to let the network grow as in the standard Barabási-Albert model. Surprisingly, the latter feature holds true also when the fraction of known nodes goes asymptotically to zero. Analytical results are compared to direct simulations.

    The purpose of this resource is to show how graphs of GLOBE data over time show the interconnectedness of Earth's system components at the local level. Students visit a study site, where they observe and recall their existing knowledge of air, water, soil, and living things to make a list of interconnections among the four Earth system components. They make predictions about the effects of a change in a system, inferring ways these changes affect the characteristics of other related components.

  3. The moderating role of father's care on the onset of binge eating symptoms among female late adolescents with insecure attachment.

    2012-04-01

    The present study examined the association between quality of attachment, perception of the father's bond, and binge eating symptoms in a sample of female late adolescents. In total, 233 female students aged between 18 and 20 years completed measures on binge eating, quality of attachment and parent-child relationship. Data showed that respondents with binge symptoms reported lower scores on secure attachment and father's care, and higher scores on preoccupied and fearful attachment. Binge eating symptoms were associated with father's care, but not with father's overprotection. Also, binge symptoms were negatively associated with secure attachment styles, and positively with preoccupied and fearful attachment. The data, finally, provided evidence that at higher levels of preoccupied attachment, the impact of binge symptoms tended to be lower when father's care was high. PMID:22076662

    A completely extruded talus without any remaining soft tissue attachments is extremely rare. The present report describes treatment of a 45-year-old man who sustained a completely extruded talus injury following a rock-climbing fall. Upon admission, the extruded talus was deep-frozen in our bone bank. The open ankle joint underwent massive wound debridement and irrigation for 3 days. Four days later we performed a primary subtalar fusion between the extruded talus and the calcaneus, anticipating revascularization from the calcaneus. However, aseptic loosening and osteolysis developed around the screw and talus. At 12 months post-trauma we performed a tibiocalcaneal ankle fusion with a femoral head allograft to fill the talar defect. Follow-up at 24 months post-trauma showed the patient had midfoot motion, tibio-talar-calcaneal fusion, and was able partake in 4-hour physical activity twice per week. PMID:24765266

    Dissociative electron attachment (DEA) to acetone is studied in terms of the absolute cross section for various fragment channels in the electron energy range of 0–20 eV. H{sup ?} is found to be the most dominant fragment followed by O{sup ?} and OH{sup ?} with only one resonance peak between 8 and 9 eV. The DEA dynamics is studied by measuring the angular distribution and kinetic energy distribution of fragment anions using Velocity Slice Imaging technique. The kinetic energy and angular distribution of H{sup ?} and O{sup ?} fragments suggest a many body break-up for the lone resonance observed. The ab initio calculations show that electron is captured in the multi-centered anti-bonding molecular orbital which would lead to a many body break-up of the resonance.

    In this paper we develop a model for the evolution of multiple networks which is able to replicate the concentrated and sparse nature of world trade data. Our model is an extension of the preferential attachment growth model to the case of multiple networks. Countries trade a variety of goods of different complexity. Every country progressively evolves from trading less sophisticated to high-tech goods. The probabilities of capturing more trade opportunities at a given level of complexity and of starting to trade more complex goods are both proportional to the number of existing trade links. We provide a set of theoretical predictions and simulative results. A calibration exercise shows that our model replicates the same concentration level of world trade as well as the sparsity pattern of the trade matrix. We also discuss a set of numerical solutions to deal with large multiple networks. PMID:25215791

    1981-01-01

    A method for purifying wastewater of biodegradable organics by converting the organics to methane and carbon dioxide gases is disclosed, characterized by the use of an anaerobic attached film expanded bed reactor for the reaction process. Dilute organic waste material is initially seeded with a heterogeneous anaerobic bacteria population including a methane-producing bacteria. The seeded organic waste material is introduced into the bottom of the expanded bed reactor which includes a particulate support media coated with a polysaccharide film. A low-velocity upward flow of the organic waste material is established through the bed during which the attached bacterial film reacts with the organic material to produce methane and carbon dioxide gases, purified water, and a small amount of residual effluent material. The residual effluent material is filtered by the film as it flows upwardly through the reactor bed. In a preferred embodiment, partially treated effluent material is recycled from the top of the bed to the bottom of the bed for further treatment. The methane and carbon dioxide gases are then separated from the residual effluent material and purified water.

The low energy cross section peaks at about 10 square Angstroms between 0.1 and 0.2 eV. The energy is in agreement with Olthoff's(J.K. Olthoff, Ph.D. Dissertation, University of Maryland (1985).) unpublished relative measurements. Due to the size of this cross section, its position relative to the BCl3 vibrational excitation thresholds, and to the Ramsauer minimum in the Ar momentum transfer cross section, its effects on the drift velocities measured(D.L. Mosteller, Jr., et al.), J. Appl. Phys. 74, 2247 (1993). in Ar/BCl3 mixtures is expected to be significant.

    National Orange Show Photovoltaic Demonstration created a 400KW Photovoltaic self-generation plant at the National Orange Show Events Center (NOS). The NOS owns a 120-acre state fairground where it operates an events center and produces an annual citrus fair known as the Orange Show. The NOS governing board wanted to employ cost-saving programs for annual energy expenses. It is hoped the Photovoltaic program will result in overall savings for the NOS, help reduce the State's energy demands as relating to electrical power consumption, improve quality of life within the affected grid area as well as increase the energy efficiency of buildings at our venue. In addition, the potential to reduce operational expenses would have a tremendous effect on the ability of the NOS to service its community.

    2009-01-01

    SYNOPSIS Objective The purpose of this study to consider whether attachment security in mothers and fathers promotes more successful early coparenting adjustment, to assess the role of marital quality in amplifying or diminishing any such effects, and to examine interactive effects of maternal and paternal attachment status on coparenting. Design Eighty-five couples transitioning to new parenthood completed Main and Goldwyn’s Adult Attachment Interview (AAI) and a multimethod marital evaluation during the pregnancy’s third trimester and participated in comprehensive assessments of coparenting conflict and cohesion at 3 months postpartum. Results Maternal Insecure attachment status predicted higher levels of coparental conflict, as did father Secure status. Families with Insecure fathers exhibited lower coparental cohesion on the whole. Maternal attachment status moderated the relation between paternal attachment status and cohesion, with Insecure father/Secure mother dyads exhibiting the lowest levels of cohesion, and Secure/Secure dyads showing the highest levels. Prenatal marital quality predicted 3-month coparenting cohesion, but not conflict. Prenatal marital quality did not interact with parental attachment status in the prediction of coparenting, but relations between parents’ attachment status and coparenting maintained after controlling for marital quality. Conclusion Prenatally assessed attachment status in both mothers and fathers predicts dimensions of coparenting early in the family life cycle. The impact of attachment status differs in important ways as a function of parent gender, and security in some cases exacerbated rather than buffered the negative impact of partner insecurity on coparental functioning. Effects of parental attachment security on coparenting cannot be properly estimated without reference to contextual factors. PMID:19662107

    Network attached storage devices improve I/O performance by separating control and data paths and eliminating host intervention during the data transfer phase. Devices are attached to both a high speed network for data transfer and to a slower network for control messages. Hierarchical mass storage systems use disks to cache the most recently used files and a combination of robotic and manually mounted tapes to store the bulk of the files in the file system. This paper shows how queuing network models can be used to assess the performance of hierarchical mass storage systems that use network attached storage devices as opposed to host attached storage devices. Simulation was used to validate the model. The analytic model presented here can be used, among other things, to evaluate the protocols involved in 1/0 over network attached devices.

  14. Development of an attachment-informed measure of sexual behavior in late adolescence.

    2013-04-01

    There is considerable interest in relations between sexual behavior and romantic attachment styles in adolescence as attachment needs are increasingly met through intimate partners rather than parents. The objectives of this research were to organize a measure of sexual behavior within an attachment theory framework, and then show that this new measure uniquely predicted sexual approach styles and invasive sexual experiences. 190 18- and 19-year-old university students in late adolescence completed sexual behavior items that were provided ambivalent (anxious) and avoidant dimensions. These were systematically related to the romantic attachment dimensions of the Experiences in Close Relationships - Revised. However, even after romantic relationship style, gender, and social desirability were controlled, avoidance in sexual relationships predicted lifetime sexual partner number and negatively predicted positive sexual strategies, and ambivalence in sexual relationships predicted invasive and coercive sexual behaviors. A measure specific to sexual relationships informs the attachment and romantic context of sex in late adolescence. PMID:23414943

    2013-11-01

    Social networking sites (SNS) like Facebook can increase interpersonal connections but also intensify jealousy, envy, and surveillance behaviors. Attachment styles may help explain differences in experiencing SNS. This study investigated the role of attachment in influencing emerging adults' perceptions and feelings about SNS and their disclosures on SNS. Disorganized and anxious attachment predicted subjects' use of SNS to avoid more personal face-to-face communication, suggesting individuals with these tendencies use SNS to hold relationships at a psychological arm's distance. Anxious attachment also predicted feelings of intimacy when using SNS, perhaps reflecting online needs for comfort from others. A case narrative is presented to show how those with insecure attachment patterns may struggle to avoid interpersonal conflict when being continuously presented with ambiguous social information.

    As the optimal source of astaxanthin, Haematococcus pluvialis was cultured for commercial production of astaxanthin through two continuous phases: cell growth and astaxanthin induction. In this study, the efficiency of an attached system for producing astaxanthin from H. pluvialis was investigated and compared to that of the suspended system (bubble column bioreactor) under various conditions. Results showed that this attached system is more suitable for photoinduction of H. pluvialis than the suspended bioreactor. Under the optimal conditions, the astaxanthin productivity of the attached system was 65.8 mg m(-2)d(-1) and 2.4-fold of that in the suspended system. This attached approach also offers other advantages over suspended systems, such as, producing astaxanthin under a wide range of light intensities and temperatures, saving water, ease to harvest cells, resisting contamination. Therefore, the attached approach can be considered an economical, environmentally friendly and highly-efficient technology for producing astaxanthin from H. pluvialis. PMID:24787315

    This study examined associations between attachment insecurity and autonomic response during the Adult Attachment Interview (AAI) in a sample of 47 women with eating disorders using a new system for the synchronous acquisition of behavioral and physiological data: the Bio Dual-channel and Representation of Attachment Multimedia System (BioDReAMS; Soares, Cunha, Zhan Jian Li, Pinho, & Neves, 1998). Consistent with the emerging literature on the psychophysiology of adult attachment, insecurity was positively correlated with electrodermal reactivity during the AAI. Furthermore, relatively secure patients showed some evidence of parasympathetic withdrawal, which can be conceptualized as evidence of more effective emotion regulation. Results suggest that, even among women with diagnosed psychopathology, security is associated with moreproductive patterns of psychophysiological response to attachment-related challenges.

    This study was carried out on the moderating effect of peer attachment on the relationships between religiosity and worldview, and on how hedonistic behaviour among Malaysian undergraduate students is shaped by such influences. With regard to peer attachment, the study focused on the influences of communication, trust and alienation among youth. Bronfenbrenner's theory of human ecology and Armsden and Greenberg's attachment model were used as the framework. Drawing on a quantitative survey of 394 Malaysian university students (M age = 21.0, SD = 0.40), structural equation modelling and path analysis revealed a significant relationship between worldview and hedonistic behaviour. Peer attachment moderated the relationships between religiosity and religious worldview. The results further showed that the unique moderating effect of the lower level of attachment with peers is positively related to the hedonistic behaviour. Implications from the findings are discussed. PMID:25431513

    Rate constants for dissociative electron attachment to Cl2 have been measured from 300 to 1100 K in a high-temperature flowing-afterglow Langmuir-probe apparatus. R -matrix calculations have been carried out which compare well with the present measurements with possible deviation at the highest temperatures. The attachment rate constants do not show Arrhenius behavior. The temperature dependence of the calculated rate constants for successive vibrational levels provides insight as to this behavior. While the lowest vibrational level of Cl2 dominates attachment at low temperatures, the rate constant is not flat with temperature because of the p -wave character of the attachment process. The non-Arrhenius behavior is due to a conflict between the increase in attachment cross section with vibrational level (temperature) and the decline in the cross section with electron energy above 50 meV.

    Infants in foster care need sensitive, responsive caregivers to promote their healthy outcomes. The current study examined the effectiveness of the Attachment and Biobehavioral Catch-up Intervention, a short-term, targeted, attachment-based intervention program designed to promote sensitive caregiving behavior among foster mothers. Ninety-six foster mother–infant dyads participated in this study; 44 dyads were assigned to the Attachment and Biobehavioral Catch-up Intervention, and 52 dyads were assigned to a control intervention. Results of hierarchical linear modeling indicated that foster mothers who were assigned to the Attachment and Biobehavioral Catch-up Intervention showed greater improvements in their sensitivity from pre- to postintervention assessment time points when compared with foster mothers who were assigned to the control intervention. We conclude that a short-term, targeted, attachment-based intervention is effective in changing foster mothers’ responsiveness to their foster infants, which is critical for foster infants’ healthy socioemotional adjustment.

    2011-01-01

    We analyze whether preferential attachment in scientific coauthorship networks is different for authors with different forms of centrality. Using a complete database for the scientific specialty of research about "steel structures," we show that betweenness centrality of an existing node is a significantly better predictor of preferential attachment by new entrants than degree or closeness centrality. During the growth of a network, preferential attachment shifts from (local) degree centrality to betweenness centrality as a global measure. An interpretation is that supervisors of PhD projects and postdocs broker between new entrants and the already existing network, and thus become focal to preferential attachment. Because of this mediation, scholarly networks can be expected to develop differently from networks which are predicated on preferential attachment to nodes with high degree centrality.

  9. Effects of pitch accents in attachment ambiguity resolution

    PubMed Central

    Lee, Eun-Kyung; Watson, Duane G.

    2011-01-01

    Previous work has found that listeners prefer to attach ambiguous syntactic constituents to nouns produced with a pitch accent (Schafer et al., 1996). This study examines what factors underlie previously established accent attachment effects by testing whether these effects are driven by a preference to attach syntactic constituents to new or important information (the Syntax Hypothesis) or whether there is a bias to respond to post-sentence probe questions with an accented word (the Salience Hypothesis). One of the predictions of the Salience Hypothesis is that selection of accented words should be greater when a sentence is complex and processing resources are limited. The results from the experiments presented here show that the probability of listeners’ selecting accented words when asked about the interpretation of a relative clause varies with sentence type: listeners selected accented words more frequently in long sentences than in short sentences, consistent with the predictions of the Salience Hypothesis. Furthermore, Experiment 4 demonstrates that listeners are more likely to respond to post-sentence questions with accented words than with non-accented words, even when no ambiguity is present, and even when the response results in an incorrect answer. These findings suggest that accent-driven attachment effects found in earlier studies reflect a post-sentence selection process rather than a syntactic processing mechanism. PMID:22287815

    Clinical theorists have suggested that disturbed attachments are central to borderline personality disorder (BPD) psychopathology. This article reviews 13 empirical studies that examine the types of attachment found in individuals with this disorder or with dimensional characteristics of BPD. Comparison among the 13 studies is handicapped by the variety of measures and attachment types that these studies have employed. Nevertheless, every study concludes that there is a strong association between BPD and insecure attachment. The types of attachment found to be most characteristic of BPD subjects are unresolved, preoccupied, and fearful. In each of these attachment types, individuals demonstrate a longing for intimacy and—at the same time—concern about dependency and rejection. The high prevalence and severity of insecure attachments found in these adult samples support the central role of disturbed interpersonal relationships in clinical theories of BPD. This review concludes that these types of insecure attachment may represent phenotypic markers of vulnerability to BPD, suggesting several directions for future research. PMID:15204804

    Previous studies have implicated attachment and disturbances in romantic relationships as important indicators for Borderline Personality Disorder (BPD). The current research extends our current knowledge by examining the specific associations among attachment, romantic relationship dysfunction, and BPD, above and beyond the contribution of emotional distress and nonromantic interpersonal functioning in two distinct samples. Study 1 comprised a community sample of women (N = 58) aged 25–36. Study 2 consisted of a psychiatric sample (N = 138) aged 21–60. Results from both Study 1 and Study 2 demonstrated that (1) attachment was specifically related to BPD symptoms and romantic dysfunction, (2) BPD symptoms were specifically associated with romantic dysfunction, and (3) the association between attachment and romantic dysfunction was statistically mediated by BPD symptoms. The findings support specific associations among attachment, BPD symptoms, and romantic dysfunction. PMID:22217225

    Agrobacterium tumefaciens binds to the surfaces of inanimate objects, plants, and fungi. These bacteria are excellent colonizers of root surfaces. In addition, they also bind to soil particles and to the surface of artificial or man-made substances, such as polyesters and plastics. The mechanisms of attachment to these different surfaces have not been completely elucidated. At least two types of binding have been described unipolarpolysaccharide-dependent polar attachment and unipolar polysaccharide-independent attachment (both polar and lateral). The genes encoding the enzymes for the production of the former are located on the circular chromosome, while the genes involved in the latter have not been identified. The expression of both of these types of attachment is regulated in response to environmental signals. However, the signals to which they respond differ so that the two types of attachment are not necessarily expressed coordinately. PMID:24926300

    We address several different Casimir experiments where theory and experiment disagree. First out is the classical Casimir force measurement between two metal half spaces; here both in the form of the torsion pendulum experiment by Lamoreaux and in the form of the Casimir pressure measurement between a gold sphere and a gold plate as performed by Decca et al.; theory predicts a large negative thermal correction, absent in the high precision experiments. The third experiment is the measurement of the Casimir force between a metal plate and a laser irradiated semiconductor membrane as performed by Chen et al.; the change in force with laser intensity is larger than predicted by theory. The fourth experiment is the measurement of the Casimir force between an atom and a wall in the form of the measurement by Obrecht et al. of the change in oscillation frequency of a {sup 87}Rb Bose-Einstein condensate trapped to a fused silica wall; the change is smaller than predicted by theory. We show that saturation effects can explain the discrepancies between theory and experiment observed in all these cases.

    Recently, we reported the expression and glycosylation of avian metapneumovirus attachment glycoprotein (AMPV/C G protein) in eukaryotic cell lines by a transient-expression method. In the present study, we investigated the biosynthesis and O-linked glycosylation of the AMPV/C G protein in a baculovirus expression system. The results showed that the insect cell-produced G protein migrated more rapidly in SDS-PAGE as compared to LLC-MK2 cell-derived G proteins owing to glycosylation differences. The fully processed, mature form of G protein migrated between 78 and 86 kDa, which is smaller than the 110 kDa mature form of G expressed in LLC-MK2 cells. In addition, several immature G gene products migrating at 40-48 and 60-70 kDa were also detected by SDS-PAGE and represented glycosylated intermediates. The addition of the antibiotic tunicamycin, which blocks early steps of glycosylation, to insect cell culture resulted in the disappearance of two glycosylated forms of the G protein and identified a 38 kDa unglycosylated precursor. The maturation of the G protein was completely blocked by monensin, suggesting that the O-linked glycosylation of G initiated in the trans-Golgi compartment. The presence of O-linked sugars on the mature protein was further confirmed by lectin Arachis hypogaea binding assay. Furthermore, antigenic features of the G protein expressed in insect cells were evaluated by ELISA. PMID:20713098

    Attachment security towards parents and peers in adolescence, and romantic attachment styles and emotion regulation strategies in young adulthood, were evaluated using an eight-year longitudinal design. Fifty-six young adults completed the Inventory of Parent and Peer Attachment (IPPA) at age 14, and then, at age 22, the Experience in Close Relationships (ECR) and the Coping Inventory for Stressful Situations (CISS), an emotion regulation questionnaire concerning coping strategies, including task-oriented versus emotion-oriented foci. Results indicated that greater insecurity to parents and peers in adolescence predicted a more anxious romantic attachment style and greater use of emotion-oriented strategies in adulthood. Concurrently, anxious adult attachment style was related to more emotion-oriented strategies, whereas an avoidant attachment style was related to less support-seeking. Analyses also identified emotion-oriented coping strategies as a partial mediator of the link between adolescent attachment insecurity to parents and adult anxious attachment, and a complete mediator of the association between adolescent attachment insecurity to peers and adult anxious attachment. These findings support the core assumption of continuity in attachment theory, where relationships to parents influence close romantic relationships in adulthood. PMID:23216393

    2008-01-01

    Surfaces with nanophase compared to conventional (or nanometer smooth) topographies are known to have different properties of area, charge, and reactivity. Previously published research indicates that the attachment of certain bacteria (such as Pseudomonas fluorescens 5RL) is higher on surfaces with nanophase compared to conventional topographies, however, their effect on bacterial metabolism is unclear. Results presented here show that the adhesion of Pseudomonas fluorescens 5RL and Pseudomonas putida TVA8 was higher on nanophase than conventional titania. Importantly, in terms of metabolism, bacteria attached to the nanophase surfaces had higher bioluminescence rates than on the conventional surfaces under all nutrient conditions. Thus, the results from this study show greater select bacterial metabolism on nanometer than conventional topographies, critical results with strong consequences for the design of improved biosensors for bacteria detection.

  16. The role of attachment style in facebook use and social capital: evidence from university students and a national sample.

    PubMed

    2015-03-01

    Social networking sites (SNSs) can be beneficial tools for users to gain social capital. Although social capital consists of emotional and informational resources accumulated through interactions with strong or weak social network ties, the existing literature largely ignores attachment style in this context. This study employed attachment theory to explore individuals' attachment orientations toward Facebook usage and toward online and offline social capital. A university student sample (study 1) and a representative national sample (study 2) showed consistent results. Secure attachment was positively associated with online bonding and bridging capital and offline bridging capital. Additionally, secure attachment had an indirect effect on all capital through Facebook time. Avoidant attachment was negatively associated with online bonding capital. Anxious-ambivalent attachment had a direct association with online bonding capital and an indirect effect on all capital through Facebook. Interaction frequency with good friends on Facebook positively predicted all online and offline capital, whereas interaction frequency with average friends on Facebook positively predicted online bridging capital. Interaction frequency with acquaintances on Facebook was negatively associated with offline bonding capital. The study concludes that attachment style is a significant factor in guiding social orientation toward Facebook connections with different ties and influences online social capital. The study extends attachment theory among university students to a national sample to provide more generalizable evidence for the current literature. Additionally, this study extends attachment theory to the SNS setting with a nuanced examination of types of Facebook friends after controlling extraversion. Implications for future research are discussed. PMID:25751049

    Results from a joint experimental and theoretical study of electron attachment to chloroform (CHCl3) molecules in the gas phase are reported. In an electron swarm study involving a pulsed Townsend technique with equal gas and electron temperatures, accurate attachment rate coefficients were determined over the temperature range 295-373 K; they show an Arrhenius-type rise with increasing temperature, corresponding to an activation energy of 0.11(1) eV. In a high resolution electron beam experiment involving two versions of the laser photoelectron attachment method, the relative cross section for Cl- formation from CHCl3 over the energy range 0.001-1.25 eV at the gas temperature TG = 300 K was measured. It exhibits clear downward cusp structure at the threshold for excitation of one quantum of the vibrational symmetric deformation mode [nu]3, indicating that this mode is active in the primary attachment process. With reference to our thermal attachment rate coefficient k(T = 300 K) = 3.9(2) × 10-9 cm3 s-1, a new highly resolved absolute attachment cross section for TG = 300 K was determined. This cross section is extended to higher energies by measurements, carried out with a pulsed electron beam apparatus which also provided new data for the distinctly weaker fragment anions HCl2- and CCl2-. The resulting total absolute cross section for anion formation is used to calculate the dependence of the attachment rate coefficient k(Te;TG) on electron temperature Te over the range 50-15000 K at the fixed gas temperature TG = 300 K. In addition, we report the dependence of the relative cross section for Cl- formation on gas temperature (TG = 310-435 K). For comparison with the experimental data, R-matrix calculations have been carried out for the dominant anion channel Cl-. The results recover the main experimental observations and predict the dependence of the DEA cross section on the initial vibrational level [nu]3 and on the vibrational temperature. Our results are compared with those of previous electron beam and electron swarm experiments.

  18. NANOINDENTATION OF THE INSERTIONAL ZONES OF HUMAN MENISCAL ATTACHMENTS INTO UNDERLYING BONE

    The fibrocartilagenous knee menisci are situated between the femoral condyles and tibia plateau and are primarily anchored to the tibia by means of four attachments at the anterior and posterior horns. Strong fixation of meniscal attachments to the tibial plateau provide resistance to extruding forces of the meniscal body, allowing the menisci to assist in load transmission from the femur to the tibia. Clinically, tears and ruptures of the meniscal attachments and insertion to bone are rare. While it has been suggested that the success of a meniscal replacement is dependent on several factors, one of which is the secure fixation and firm attachment of the replacement to the tibial plateau, little is known about the material properties of meniscal attachments and the transition in material properties from the meniscus to subchondral bone. The objective of this study was to use nanoindentation to investigate the transition from meniscal attachment into underlying subchondral bone through uncalcified and calcified fibrocartilage. Nanoindentation tests were performed on both the anterior and posterior meniscal insertions to measure the instantaneous elastic modulus and elastic modulus at infinite time. The elastic moduli were found to increase in a bi-linear fashion from the external ligamentous attachment to the subchondral bone. The elastic moduli for the anterior attachments were consistently larger than those for the matching posterior attachments at similar indentation locations. These results show that there is a gradient of stiffness from the superficial zones of the insertion close to the ligamentous attachment into the deeper zones of the bone. This information will be useful in the continued development of successful meniscal replacements and understanding of fixation of the replacements to the tibial plateau. PMID:19627840

  19. Using arc voltage to locate the anode attachment in plasma arc cutting

    NASA Astrophysics Data System (ADS)

    Plasma arc cutting is a widely used industrial process in which an electric arc in the form of a high velocity plasma jet is used to melt and blow away metal. The arc attaches inside the resulting cut slot, or kerf, where it both provides a large heat flux and determines the flow dynamics of the plasma. Knowledge of the position of the arc attachment is essential for understanding the phenomena present at the work piece. This work presents a new method of measuring the location of the arc attachment in which the arc voltage is measured during the cutting of a range of work piece thicknesses. The attachment location is then interpreted from the voltages. To support the validity of this method, the kerf shape, dross particle size and dross adhesion to the work piece are also observed. While these do not conclusively give an attachment location, they show patterns which are consistent with the attachment location found from the voltage measurements. The method is demonstrated on the cutting of mild steel, where the arc attachment is found to be stationary in the upper portion of the cut slot and in reasonable agreement with existing published findings. For a process optimized for the cutting of 12.7 mm mild steel, the attachment is found at a depth of 1.5-3.4 mm. For a slower process optimized for the cutting of 25.4 mm mild steel, the attachment is found at a depth of 3.4-4.8 mm, which enhances heat transfer further down in the kerf, allowing cutting of the thicker work piece. The use of arc voltage to locate the position of the arc attachment is unique when compared with existing methods because it is entirely independent of the heat distribution and visualization techniques.

  20. Coexistence in preferential attachment networks

    Competition in markets is ubiquitous: cell-phone providers, computer manufacturers, and sport gear brands all vie for customers. Though several coexisting competitors are often observed in empirical data, many current theoretical models of competition on small-world networks predict a single winner taking over the majority of the network. We introduce a new model of product adoption that focuses on word-of-mouth recommendations to provide an explanation for this coexistence of competitors. The key property of our model is that customer choices evolve simultaneously with the network of customers. When a new node joins the network, it chooses neighbors according to preferential attachment, and then chooses its type based on the number of initial neighbors of each type. This can model a new cell-phone user choosing a cell-phone provider, a new student choosing a laptop, or a new athletic team member choosing a gear provider. We provide a detailed analysis of the new model; in particular, we determine the possibl...

    2015-01-01

    With the ubiquity of smartphones and the rising technology of 3D printing, novel devices can be developed that leverage the "computer in your pocket" and rapid prototyping technologies toward scientific, medical, engineering, and creative purposes. This paper describes such a device: a simple 3D-printed extension for Apple's iPhone that allows the sound from an off-the-shelf acoustic stethoscope to be recorded using the phone's built-in microphone. The attachment's digital 3D files can be easily shared, modified for similar phones and devices capable of recording audio, and in combination with 3D printing technology allow for fabrication of a durable device without need for an entire factory of expensive and specialized machining tools. It is hoped that by releasing this device as an open source set of printable files that can be downloaded and reproduced cheaply, others can make use of these developments where access to cost-prohibitive, specialized medical instruments are not available. Coupled with specialized smartphone software ("apps"), more sophisticated and automated diagnostics may also be possible on-site. PMID:25626549

    Most modern theories suggest that interpersonal relationships are of central importance in the development of criminal behavior. We tested the parent attachment scales of a new research and clinical measure, the Attachment and Clinical Issues Questionnaire (ACIQ). It is a 29-scale battery assessing attachments to mother, father, partner, and peers, which also includes several related clinical scales. Sixty-one (18-20 years of age) male offenders from a maximum security detention center and 131contrasts completed the ACIQ. ANOVA demonstrated that mother and father attachments displayed different patterns. The attachment scales also predicted the numbers of crimes within the population of juvenile offenders. Thus, the parent attachment scales of the ACIQ showed promise as an instrument to test dynamic systems approaches to developmental models of criminal behavior. PMID:23788289

    A reusable system is described for removably attaching a nuclear reactor fuel rod to a support member. A locking cap is secured to the fuel rod and a locking strip is fastened to the support member. The locking cap has two opposing fingers shaped to form a socket having a body portion. The locking strip has an extension shaped to rigidly attach to the socket's body portion. The locking cap's fingers are resiliently deflectable. For attachment, the locking cap is longitudinally pushed onto the locking strip causing the extension to temporarily deflect open the fingers to engage the socket's body portion. For removal, the process is reversed.

    A major concern with the Space Station Freedom (SSF) water supply system is the control of longterm microbial contamination and biofilm development in the water storage and distribution systems. These biofilms have the potential for harboring pathogens as well as microbial strains containing resistance factors that could negatively influence crew health. The proposed means for disinfecting the water system on SSF (iodine) may encourage the selection of resistant strains. In fact, biofilm bacteria were observed in water lines from the Space Shuttle Columbia (OV-102); therefore, an alternative remediation method is required to disinfect spacecraft water lines. A thorough understanding of colonization events and the physiological parameters that will influence bacteria adhesion is required. The limiting factor for development of this technology is the ability to continuously monitor adhesion events and the effects of biocides on sessile bacteria. Methods were developed to allow bacterial adhesion and subsequent biocidal treatment to be monitored continuously. This technique couples automated image analysis with a continuous flow of a bacterial suspension through an optical flow cell. A strain of Pseudomonas cepacia isolated from the water supply of the Space Shuttle Discovery (OV-103) during STS-39 was grown in a nitrogen-limited continuous culture. This culture was challenged continuously with iodine during growth, and the adhesion characteristics of this strain was measure with regard to flow rate. Various biocides (ozone, hypochlorite, and iodine) were added to the flow stream to evaluate how well each chemical removed the bacteria. After biocide treatment, a fresh bacterial suspension was introduced into the flow cell, and the attachment rate was evaluated on the previously treated surface. This secondary fouling was again treated with biocide to determine the efficacy of multiple batch chemical treatments in removing biofilm.

    The study investigated the transfer of attachment working models onto autonomous agents in a virtual social environment (VSE). Participants from a community sample (N?=?422; mean age?=?29 years; mean relationship duration?=?4.8 years) encountered three attachment-related key scenes in a VSE: a separation with a subsequent reunion, a conflict, and an illness. In these scenarios, participants gave instructions to the main character (the "protagonist"), who had a romantic relationship with one of the other agents (the "virtual spouse"). Recorded were numerous behaviors as well as emotions participants ascribed to the protagonist. Generally, participants' attachment styles correlated as predicted with their behavior toward the virtual spouse, with ?s up to.42. Thus, the study demonstrates that internal working models are transferred to the virtual relationship. This approach opens new ways to investigate attachment-related behavior by using VSEs that allow experimental variations of the virtual partner's reactions and other situational variables.

    This research was aimed at providing first evidence concerning the relationship between adults' self-reported attachment style and their performance on a standard 'theory of mind' task. Based on adult attachment theory, we hypothesized that the two dimensions of self-reported adult attachment, anxiety and avoidance, are differently related to 'theory of mind,' and that this relationship is moderated by variables concerning the 'theory of mind' stimuli. The 'Experiences in Close Relationships' questionnaire and the 'Reading the Mind in the Eyes' test were administered to 132 young women. In line with our expectations, women's attachment-related anxiety was associated with better mind reading concerning stimuli that were emotionally neutral or difficult to recognize. PMID:23529700

    NASA Glenn Research Center was contacted to provide technical support to NASA Ames Research Center in the design and analysis of an ultra high temperature ceramic (UHTC) leading edge. UHTC materials are being considered for reusable launch vehicles because their high temperature capability may allow for un-cooled sharp leading edge designs. While ceramic materials have the design benefit of allowing subcomponents to run hot, they also provide a design challenge in that they invariably must be in contact with cooler subcomponents elsewhere in the structure. NASA Glenn Research Center proposed a modification to an existing attachment design. Thermal and structural analyses of the leading edge assembly were carried out using ABAQUS finite element software. Final results showed that the proposed modifications aided in thermally isolating hot and cold subcomponents and reducing bearing stresses at the attachment location.

    Attachment to a substrate and survival of human embryonic kidney (HEK) cells have been tested in an incubator installed in the flight-deck of the Space Shuttle 'Challenger' during its eighth mission. HEK cells are producing the enzyme urokinase and are presently investigated as candidates for electrophoretic separation in an apparatus developed and manufactured by McDonnell Douglas. Attachment of HEK cells to a substrate is mandatory for survival and production of urokinase after electrophoretic separation. Analysis of the samples shows that cells adhere, spread and survive in microgravity (< 10(-3) x g) conditions as well as the ground controls at 1 x g. This result represents an important step towards further bioprocessing in space. PMID:11540837

    Connection topologies of many networked systems like human brain, biological cell, world wide web, power grids, human society and ecological food webs markedly deviate from that of completely random networks indicating the presence of organizing principles behind their evolution. The five important features that characterize such networks are scale-free topology, small average path length, high clustering, hierarchical community structure and assortative mixing. Till now the generic mechanisms underlying the existence of these properties are not well understood. Here we show that potentially a single mechanism, which we call "mediated attachment", where two nodes get connected through a mediator or common neighbor, could be responsible for the emergence of all important properties of real networks. The mediated attachment naturally unifies scale-free topology, high clustering, small world nature, hierarchical community structure and dissortative nature of networks. Further, with additional mixing by age, this...

  20. Parental bonds, attachment anxiety, media susceptibility, and body dissatisfaction: a mediation model.

    2014-08-01

    The developmental trajectory of body image dissatisfaction is unclear. Researchers have investigated sociocultural and developmental risk factors; however, the literature needs an integrative etiological model. In 2009, Cheng and Mallinckrodt proposed a dual mediation model, positing that poor-quality parental bonds, via the mechanisms of heightening romantic attachment anxiety and thin-ideal media internalization, increases body dissatisfaction. We tested 2 versions of this model, including an alternate model featuring attachment anxiety in close friendships. We recruited females ages 12-24, primarily from a mid-sized private religious university, to complete self-report measures. The participant sample was ethnically diverse, with approximately 40% endorsing minority status. Results showed that mother care and father care were negatively linked to friendship attachment anxiety and romantic attachment anxiety. Friendship and romantic attachment anxiety were positively linked to media susceptibility. Media susceptibility was positively linked to body image dissatisfaction. Mother care and father care were negatively, indirectly linked to body image dissatisfaction through the mediators of friendship attachment anxiety and media susceptibility. Mother care made a significant, albeit small, contribution to body image dissatisfaction after controlling for other variables. Overall, findings suggest that adverse parent-child relational factors may indirectly elevate body dissatisfaction, operating through attachment anxiety and susceptibility to sociocultural pressures.

    In a combined experimental and theoretical effort, we have investigated dissociative attachment and vibrational excitation in low-energy electron collisions with chlorine molecules. Using the laser photoelectron attachment method, we have measured the energy dependence of the cross section sgrDA(E) for dissociative electron attachment (Cl- formation) over the range 0-195 meV with an energy width of 1-3 meV and for Rydberg electron transfer at high principal quantum numbers (n>67). Near zero energy, the cross section shows a behaviour compatible with the threshold law for p-wave attachment via the 2Sgru+ resonance, reaches a maximum around 50 meV and declines towards higher energies. These findings are in good agreement with the results of semi-empirical R-matrix calculations. Measured rate coefficients knl for Cl- formation due to electron transfer from K**(nl) Rydberg atoms were found to be nearly constant for high principal quantum numbers (n>67) in contrast to the behaviour expected within the quasi-free electron model for p-wave attachment. The R-matrix calculations are extended to describe electron attachment through the 2Pgrg and 2Pgru resonances, and recommended absolute cross sections for dissociative attachment to chlorine molecules at room temperature are provided over the energy range 0-9 eV. Furthermore, we predict cross sections for vibrationally inelastic electron scattering through the 2Sgru+, 2Pgrg and 2Pgru resonances.

    This study examined classifications of attachment in three groups of children in Bucharest, Romania at age 42 months. The first two groups had been placed in institutions soon after birth, assessed comprehensively and then randomly assigned to either care as usual, including institutionalization (care as usual/institutional group) or to foster care (intervention group). These groups were compared to a group of family-reared children recruited from pediatric clinics (never institutionalized group). Attachment was assessed using ratings of attachment behavior in the Strange Situation Procedure at 42 months of age. Attachment classifications for children randomly assigned to foster care were markedly different from those of children who received care as usual, particularly at the extremes of the classifications (Secure and Insecure-other). Importantly, children placed in foster care before 24 months were more likely to have secure attachments with their caregivers. In addition, children placed into foster care earlier showed more likelihood of being organized in their relationships with their caregivers. Further, cognitive status predicted greater likelihood of organized attachment for children in the Care as Usual/Institution group and greater likelihood of secure attachment in the foster care group and the never institutionalized group. These findings demonstrate that foster care is an important intervention to address the effects of early adverse rearing conditions. PMID:20331663

    The present study addresses the gap in research concerning poor marital support together with insecure attachment style explaining risk for anxiety or depression in both members of a couple expecting a baby. The Attachment Style Interview (ASI) was administered separately to both members of a couple (N = 126) during the second trimester of pregnancy together with measures of state-anxiety (STAI-S) and depression (EPDS). These measures were repeated at three months postpartum. While insecure attachment style was related to higher anxiety and depression symptoms in both partners at both time periods, there was an increase of postnatal depression symptoms in women. Poor partner support contributed to anxiety symptoms only in men. When insecure attachment combinations in both members of the couple were examined, insecure styles increased anxiety and depression symptoms in both genders antenatally, but postnatal anxiety symptoms only in women. A combined effect of partner's support and attachment style on temporal changes of anxiety symptoms was observed differently for women and men. It is important to assess attachment style and partner support of both members, as well as the mutual interplay between them, to understand gendered differences in psychological adjustment of a couple expecting a baby.

  10. Investigating Attachment Behaviors of Cryptosporidium Parvum Oocysts Using Collision Efficiency in Laboratory Column Experiments

    2009-12-01

    Cryptosporidium is one of the most common enteric parasites of humans and domestic animals, and a number of outbreaks of Cryprosporidiosis, a diarrheal disease caused by Cryptosporidium have been reported worldwide. Natural porous media has been demonstrated to be an effective filter for removing Cryptosporidium parvum from contaminated water and the amount of Cryptosporidium filtered is known to be highly dependent on physical and chemical conditions of the porous media and the water. Cryptosporidium deposition in saturated porous media involves two main steps: approach and attachment. In contrast to the approach mechanisms, attachment processes have not been systematically described to predict a priori because theories that represent attachment behavior (colloid stability) such as DLVO are insufficient to explain experimental data. For this reason, attachment efficiency is calculated based on empirical data, typically experimental breakthrough curves in laboratory columns or field experiments. In this study, collision (attachment) efficiencies (?) of C. parvum oocyst were calculated to test the effect of chemical property changes on the association of oocysts with sand grains. The breakthrough curve data obtained from twelve column experiments and three models were employed to calculate single collector efficiency (?) and ?. The first ten experiments were conducted by changing ionic strength and pH, and mixing with natural sediments under the same physical properties (same ?). Our experiment results show that iron coating or clay/suspended solids mixture drastically enhanced oocyst deposition. The experiments also showed that increase in ionic strength and decrease in pH enhanced the attachment efficiency. However, the experiment with 100mM NaCl resulted in low attachment efficiency and the experiment with pH 8.5 showed similar attachment efficiency to the one at pH 7. Based on the results from two additional experiments with different flow velocities, it appears that attachment efficiency changes when the flow velocity changes, which contradicts CFT. The results prove that predicting attachment efficiency of C. parvum oocyst using ionic strength or pH is inappropriate when non-DLVO interactions are involved. A review of our results and comparison to existing data shows that it is challenging to accurately predict the attachment efficiency using single peak value of breakthrough curve data from geochemical information of porous media.

    This research investigated how spouses' attachment styles jointly contributed to their stress responses. Newlywed couples discussed relationship conflicts. Salivary cortisol indexed physiological stress; observer-rated behaviors indexed behavioral stress; self-reported distress indexed psychological stress. Multilevel modeling tested predictions that couples including 1 anxious and 1 avoidant partner or 2 anxious partners would show distinctive stress responses. As predicted, couples with anxious wives and avoidant husbands showed physiological reactivity in anticipation of conflict: Both spouses showed sharp increases in cortisol, followed by rapid declines. These couples also showed distinctive behaviors during conflict: Anxious wives had difficulty recognizing avoidant husbands' distress, and avoidant husbands had difficulty approaching anxious wives for support. Contrary to predictions, couples including 2 anxious partners did not show distinctive stress responses. Findings suggest that the fit between partners' attachment styles can improve understanding of relationships by specifying conditions under which partners' attachment characteristics jointly influence individual and relationship outcomes.

    Exposure of Salmonella to environmental stress, prior to its adherence to a food contact surface, may change the cell surface properties and consequently affect its initial attachment and biofilm formation. This study investigated the influence of temperature and pH preacclimation on the initial attachment of Salmonella Enteritidis to acrylic and stainless steel. Besides, changes in physicochemical properties of cells were examined; and their surface attachment was modeled by xDLVO theory. Results showed that control cells pre-grown at 37°C had significantly (P<0.05) higher initial attachment, followed by those pre-grown at 25, 42, and 10°C. The initial attachment of cells pre-grown at pH 5.3 or 6.3 was not significantly (P>0.05) different from control cells pre-grown at pH 7.3, but they were significantly higher compared to cells pre-grown at pH 8.3 and 9.0. No significant difference was observed between cell attachment to acrylic and stainless steel, although they had different physicochemical properties. The xDLVO theory successfully explained higher attachment for cells pre-grown at optimal condition on both contact surfaces. However, the xDLVO theory could not explain the similar attachment of cells to acrylic and stainless steel. This study elucidates that commonly used intervention technologies including cold storage, thermal treatment, and alkaline antimicrobial agents might alter the physicochemical properties of S. Enteritidis cells and result in varied initial attachment levels. PMID:25800356

    The attachment of viruses in the soil-water matrix is an important issue in environmental microbial risk assessment. The effects of different soil properties on the attachment of viruses have been studied using surrogate viruses known as bacteriophages. However, there have been few attempts to link those properties together to give an overall picture of the attachment dynamics. This study measured the attachment of bacteriophages MS2 and ØX174 to 27 natural, highly characterized soils. Statistical analysis was used to identify and rank the soil properties that facilitate virus attachment. Soil samples were mixed with artificial groundwater diluent and 1ml of bacteriophages for 3 hours. Attachment was measured by the reduction in phage titre in the supernatant (SS) relative to controls minus the soil (CS), and was presented as the ratio of SS/CS. The examined soil properties were pH, particle size distribution, moisture content, heterotrophic plate count, total nitrogen, total carbon, extractable acidity (H+) and cations (barium chloride method), and soil bulk X-ray diffraction. Spearman correlation was conducted between the SS/CS value and the tested soil properties. Where the SS/CS value was above 0.1, which showed minimum attachment of the bacteriophage to the soils, the attachment of MS2 was significantly enhanced (p<0.05) by Al (r = - 0.790) and Fe (r = - 0.573), whereas none of the tested elements could significantly enhance the attachment of ØX174. Where the SS/CS value was below 0.1, the attachment of MS2 was significantly inhibited (p<0.05) by H+ (r = 0.764), total nitrogen (r = 0.580) and total carbon (r = 0.713); whereas the attachment of ØX174 was significantly inhibited (p<0.05) only by H+ (r = 0.701).This preliminary result suggested that different bacteriophages may attach to the same soil with different efficiencies, affected by a different set of soil properties.

  6. Composition and substrate-dependent strength of the silken attachment discs in spiders.

    PubMed

    Grawe, Ingo; Wolff, Jonas O; Gorb, Stanislav N

    2014-09-01

    Araneomorph spiders have evolved different silks with dissimilar material properties, serving different purposes. The two-compound pyriform secretion is used to glue silk threads to substrates or to other threads. It is applied in distinct patterns, called attachment discs. Although ubiquitously found in spider silk applications and hypothesized to be strong and versatile at low material consumption, the performance of attachment discs on different substrates remains unknown. Here, we analyse the detachment forces and fracture mechanics of the attachment discs spun by five different species on three different substrates, by pulling on the upstream part of the attached thread. Results show that although the adhesion of the pyriform glue is heavily affected by the substrate, even on Teflon it is frequently strong enough to hold the spider's weight. As plant surfaces are often difficult to wet, they are hypothesized to be the major driving force for evolution of the pyriform secretion. PMID:25030386

  7. Cob-Weaving Spiders Design Attachment Discs Differently for Locomotion and Prey Capture

    2013-03-01

    Spiders' cobwebs ensnare both walking and flying prey. While the scaffolding silk can entangle flying insects, gumfoot silk threads pull walking prey off the ground and into the web. Therefore, scaffolding silk needs to withstand the impact of the prey, whereas gumfoot silk needs to easily detach from the substrate when contacted by prey. Here, we show that spiders accomplish these divergent demands by creating attachment discs of two distinct architectures using the same pyriform silk. A ``staple-pin'' architecture firmly attaches the scaffolding silk to the substrate and a previously unknown ``dendritic'' architecture weakly attaches the gumfoot silk to the substrate. Gumfoot discs adhere weakly, triggering a spring-loaded trap, while the strong adhesion of scaffolding discs compels the scaffolding threads to break instead of detaching. We describe the differences in adhesion for these two architectures using tape-peeling models and design synthetic attachments that reveal important design principles for controlled adhesion.

    Surface of chitosan membrane was modified with argon (Ar) and nitrogen (N) plasma immersion ion implantation (PIII) for human skin fibroblasts F1544 cell attachment. The modified surfaces were characterized by Fourier transform infrared spectroscopy (FTIR) and atomic force microscopy (AFM). Cell attachment patterns were evaluated by scanning electron microscopy (SEM). The enzyme-linked immunosorbent assay (ELISA) was used to quantify levels of focal adhesion kinase (FAK). The results showed that Ar PIII had an enhancement effect on the cell attachment while N-PIII had an inhibition effect. Filopodial analysis revealed more microfilament cytoplasmic spreading on the edge of cells attached on the Ar-treated membranes than N-treated membranes. Higher level FAK was found in Ar-treated membranes than that in N-treated membranes.

    Little is known about the links between anxiety disorders and parent-child attachment disorganization and quality of peer relationships in late adolescence. This study examined the quality of attachment and peer relationships among adolescents with and without anxiety disorders in a sample of 109 low- to moderate-income families. Psychopathology was assessed with the SCID-I. Attachment disorganization and dysfunction in peer relationships were measured using semi-structured interviews and behavioral observations. Adolescents with anxiety disorders and comorbid conditions showed higher levels of attachment disorganization across three measurement approaches, as well as higher levels of dysfunction in peer relationships than those with no Axis I diagnosis. Adolescents without anxiety disorders but with other Axis I disorders differed only in the quality of school relationships from those with no diagnoses. The pattern of results suggests that pathological anxiety, in the context of other comorbidities, may be a marker for more pervasive levels of social impairment. PMID:23247207

    2013-04-01

    A lathe attachment has been developed for an existing CNC machine (installed with rapid prototyping attachment) using conceptual design. The CNC machine operates on mechatronic controls and a computer interface called CAMSOFT, and is used as a CNC Lathe after installing the respective attachment to it. The conceptual design phase, starts from an idea and different components of the lathe are designed as attachment using CAD modelling and is followed by fabrication phase. The lathe attachment is successfully developed and is installed to the CNC machine. The working of the CNC Lathe attachment is checked by making some machining operation like turning and thread cutting. The machining operations are successfully done. The CNC machine becomes multifunctional with the presently developed lathe attachment and the existing RP (rapid prototyping) attachment, and can be used accordingly by installing the respective attachment to it. The CNC machine is useful for carrying research work in both the fields, when installed with the appropriate attachment.

    1982-01-01

    As part of the NASA Langley Research Center Storm Hazards Program, 69 thunderstorm pentrations were made in 1980 with an F-106B airplane in order to record direct strike lightning data and the associated flight conditions. Ground based weather radar measurements in conjunction with these penetrations were made by NOAA National Severe Storms Laboratory in Oklahoma and by NASA Wallops Flight Center in Virginia. In 1980, the airplane received 10 direct lightning strikes; in addition, lightning transient data were recorded from 6 nearby flashes. Following each flight, the airplane was thoroughly inspected for evidence of lightning attachment, and the individual lightning attachment points were plotted on isometric projections of the airplane to identify swept flash patterns. This report presents pilot descriptions of the direct strikes to the airplane, shows the strike attachment patterns that were found, and discusses the implications of the patterns with respect to aircraft protection design. The flight conditions are also included. Finally, the lightning strike scenarios for three U.S. Air Force F-106A airplanes which were struck during routine operations are given in the appendix to this paper.

    Within density functional theory, we have obtained the structure of $^4$He droplets doped with neutral calcium atoms. These results have been used, in conjunction with newly determined {\\it ab-initio} $^1\\Sigma$ and $^1\\Pi$ Ca-He pair potentials, to address the $4s4p$ $^1$P$_1 \\leftarrow 4s^2$ $^1$S$_0$ transition of the attached Ca atom, finding a fairly good agreement with absorption experimental data. We have studied the drop structure as a function of the position of the Ca atom with respect of the center of mass of the helium moiety. The interplay between the density oscillations arising from the helium intrinsic structure and the density oscillations produced by the impurity in its neighborhood plays a role in the determination of the equilibrium state, and hence in the solvation properties of alkaline earth atoms. In a case of study, the thermal motion of the impurity within the drop surface region has been analyzed in a semi-quantitative way. We have found that, although the atomic shift shows a sizeable dependence on the impurity location, the thermal effect is statistically small, contributing by about a 10% to the line broadening. The structure of vortices attached to the calcium atom has been also addressed, and its effect on the calcium absorption spectrum discussed. At variance with previous theoretical predictions, we conclude that spectroscopic experiments on Ca atoms attached to $^4$He drops will be likely unable to detect the presence of quantized vortices in helium nanodrops.

  13. Dissociative electron attachment on surfaces and in bulk media

    2007-07-01

    A theory of dissociative electron attachment to molecules condensed at surfaces and embedded within bulk media is developed. The theory of low-energy electron diffraction is used to obtain the width for electron-molecule resonance scattering in the condensed phase from the width for the gas phase. It is then employed for the calculation of dissociative attachment in the framework of the nonlocal complex potential theory. Specific calculations using the effective mass approximation are carried out for electron attachment to CH3Cl and CF3Cl molecules physisorbed on the surface of a Kr film. The role of image states and image-potential resonances is analyzed. The results show an increase by several orders of magnitude in the cross section for physisorbed molecules as compared with gas-phase molecules. This is in general agreement with the measured cross sections. However, the position of the peak in the cross section for CH3Cl is significantly shifted towards higher energies as compared to experiment [K. Nagesha , J. Chem. Phys. 114, 4934 (2001)], and the magnitude of the calculated cross section for CF3Cl at the surface is significantly higher than the measured value. Possible reasons for disagreements are analyzed.

According to the National Oceanic and Atmospheric Adminstration (NOAA), El Nino is "a disruption of the ocean-atmosphere system in the tropical Pacific having important consequences for weather around the globe." It is caused by a change in trade wind patterns in the central and western Pacific ocean, and causes a large volume of ocean to be warmed (typically about 20 degrees of latitude by 90 degrees of longitude). It happens at irregular intervals and has global climatic consequences (regional flooding and droughts, in particular).

  15. Aptamer-based polyvalent ligands for regulated cell attachment on the hydrogel surface.

    Natural biomolecules are often used to functionalize materials to achieve desired cell-material interactions. However, their applications can be limited owing to denaturation during the material functionalization process. Therefore, efforts have been made to develop synthetic ligands with polyvalence as alternatives to natural affinity biomolecules for the synthesis of functional materials and the control of cell-material interactions. This work was aimed at investigating the capability of a hydrogel functionalized with a novel polyvalent aptamer in inducing cell attachment in dynamic flow and releasing the attached cells in physiological conditions through a hybridization reaction. The results show that the polyvalent aptamer could induce cell attachment on the hydrogel in dynamic flow. Moreover, cell attachment on the hydrogel surface was significantly influenced by the value of shear stress. The cell density on the hydrogel was increased from 40 cells/mm(2) to nearly 700 cells/mm(2) when the shear stress was decreased from 0.05 to 0.005 Pa. After the attachment onto the hydrogel surface, approximately 95% of the cells could be triggered to detach within 20 min by using an oligonucleotide complementary sequence that displaced polyvalent aptamer strands from the hydrogel surface. While it was found that the cell activity was reduced, the live/dead staining results show that ?98% of the detached cells were viable. Therefore, this work has suggested that the polyvalent aptamer is a promising synthetic ligand for the functionalization of materials for regulated cell attachment. PMID:25789558

  16. In the eye of the beholder: Attachment style differences in emotion

    E-print Network

    Justin K. Meyer; Mcnair Scholar

    Attachment theory refers to the relationships individuals develop with caregivers or significant others in their lives. Specifically, adult attachment is concerned with the bond that develops between romantic partners, as categorized by four different adult attachment styles: Secure, Preoccupied, Dismissing, and Fearful. This study seeks to examine the role that adult attachment style might play in the perception of emotion in others, and whether there are individual differences in emotion perception accuracy among the different attachment styles in a sample of undergraduate college students. Based on previous research, the hypothesis was that Preoccupied individuals would show increased accuracy at perceiving emotions in others, while Dismissing individuals would show decreased accuracy at perceiving emotions in others. Attachment styles were determined through the use of the Experiences in Close Relationships-Revised inventory (ECR-R), and emotion perception accuracy was assessed using the Reading the Mind in the Eyes Task (RMET). Results indicated that while Preoccupied individuals did have increased accuracy and Dismissing individuals had decreased accuracy at perceiving emotions, this finding was confined to negative emotions. One proposed explanation for this finding is that a bias exists for Preoccupied and Dismissing individuals, and future research is suggested.

    While attachment research has demonstrated that parents' internal working models of attachment relationships tend to be transmitted to their children, affecting children's developmental trajectories, this study specifically examines associations between adult attachment status and observable parent, child, and dyadic behaviors among children with autism and associated neurodevelopmental disorders of relating and communicating. The Adult Attachment Interview (AAI) was employed to derive parental working models of attachment relationships. The Functional Emotional Assessment Scale (FEAS) was used to determine the quality of relational and functional behaviors in parents and their children. The sample included parents and their 4- to 16-year-old children with autism and associated neurodevelopmental disorders. Hypothesized relationships between AAI classifications and FEAS scores were supported. Significant correlations were found between AAI classification and FEAS scores, indicating that children with autism spectrum disorders whose parents demonstrated secure attachment representations were better able to initiate and respond in two-way pre-symbolic gestural communication; organize two-way social problem-solving communication; and engage in imaginative thinking, symbolic play, and verbal communication. These findings lend support to the relevance of the parent's state of mind pertaining to attachment status to child and parent relational behavior in cases wherein the child has been diagnosed with autism or an associated neurodevelopmental disorder of relating and communicating. A model emerges from these findings of conceptualizing relationships between parental internal models of attachment relationships and parent-child relational and functional levels that may aid in differentiating interventions.

  8. Parental incarceration, attachment and child psychopathology.

    PubMed

    Murray, Joseph; Murray, Lynne

    2010-07-01

    Theory and evidence relating parental incarceration, attachment, and psychopathology are reviewed. Parental incarceration is a strong risk factor for long-lasting psychopathology, including antisocial and internalizing outcomes. Parental incarceration might threaten children's attachment security because of parent-child separation, confusing communication about parental absence, restricted contact with incarcerated parents, and unstable caregiving arrangements. Parental incarceration can also cause economic strain, reduced supervision, stigma, home and school moves, and other negative life events for children. Thus, there are multiple possible mechanisms whereby parental incarceration might increase risk for child psychopathology. Maternal incarceration tends to cause more disruption for children than paternal incarceration and may lead to greater risk for insecure attachment and psychopathology. Children's prior attachment relations and other life experiences are likely to be of great importance for understanding children's reactions to parental incarceration. Several hypotheses are presented about how prior insecure attachment and social adversity might interact with parental incarceration and contribute to psychopathology. Carefully designed longitudinal studies, randomized controlled trials, and cross-national comparative research are required to test these hypotheses. PMID:20582842

    We explored the notion that adolescents possess mental secure base scripts of attachment-related events and examined, for the first time, whether these scripts were linked to adolescent attachment security. Results indicated that adolescents possessed a general script for mother and for father, and that they drew upon these scripts across different contexts. Adolescents' scripts for mother and for father were related, but only the scripts for mother predicted unique variance in adolescents' scripts for nonspecific others. Moreover, greater attachment security (as measured by the Adult Attachment Interview; AAI) was linked to greater access to and knowledge of secure base scripts for mothers, fathers, and nonspecific others. Only mother scripts, however, predicted unique variance in adolescents' AAI coherence of mind scores. Adolescents' romantic-attachment avoidance and anxiety scores (as assessed using the Experiences in Close Relationship Inventory) were linked negatively to scripts for mothers and nonspecific others, respectively.

    The aim of this investigation was to examine whether adolescent attachment representation (as assessed using the Adult Attachment Interview) is linked to the quality of adolescents' peer relations (as assessed using a standard battery of peer-report instruments tapping adolescents' social behaviors, peer victimization, social acceptance, and sociometric status). As expected, secure/autonomous adolescents were more likely than insecure/dismissing adolescents to be perceived as behaving prosocially, and less likely to be perceived as aggressive, shy-withdrawn, and victimized by peers. Other findings indicated that insecure/dismissing adolescents, compared to secure/autonomous adolescents, were less likely to be socially accepted by their peers. In addition, insecure/dismissing girls, compared to secure/autonomous girls, were more likely to be neglected; no attachment group differences emerged for boys, or for peer rejection. PMID:18773315

    1982-01-01

    A reusable system for removably attaching a nuclear reactor fuel rod (12) to a support member (14). A locking cap (22) is secured to the fuel rod (12) and a locking strip (24) is fastened to the support member (14). The locking cap (22) has two opposing fingers (24a and 24b) shaped to form a socket having a body portion (26). The locking strip has an extension (36) shaped to rigidly attach to the socket's body portion (26). The locking cap's fingers are resiliently deflectable. For attachment, the locking cap (22) is longitudinally pushed onto the locking strip (24) causing the extension (36) to temporarily deflect open the fingers (24a and 24b) to engage the socket's body portion (26). For removal, the process is reversed.

    2014-01-01

    Total talar extrusion without a soft tissue attachment is an extremely rare injury and is rarely reported. Appropriate treatment remains controversial. We describe the long-term outcomes of two patients who had complete talar extrusion without remaining soft tissue attachment treated with arthrodesis. Both of our patients had complications such as infection and progressive osteolysis. We suggest reimplantation of the extruded talus after thorough debridement as soon as possible as a reasonable option unless the talus is contaminated or missing, because an open wound may arise from inside to outside.

    2005-08-01

    We present results of effective range theory calculations of nondissociative electron attachment to SF6 molecules and CO2 clusters. The first process is strongly influenced by the SF-6 virtual state, and the second by vibrational Feshbach resonances associated with electron capture by the long-range polarization field of the cluster with simultaneous vibrational excitation of one molecular unit. We also study how both processes depend on the initial vibrational excitation of the target. We obtain a noticeable dependence of the attachment cross-section on the symmetric stretch vibration of SF6, although it does not lead to a significant temperature dependence at low electron energies.

    Several different tests are described which simulated the actual configuration of a cryogenic wind tunnel operating at pressures up to 5 atmospheres (507 kPa) and temperatures from -320 F (78K) to 120 F (322K) in order to determine compatible bolting, adequate sealing, and effective insulating materials. The evaluation of flange attachments (continuous threaded studs) considered bolting based on compatible flanges, attachment materials, and prescribed bolt elongations. Various types of seals and seal configurations were studied to determine suitability and reusability under the imposed pressure and temperature loadings. The temperature profile was established for several materials used for structural supports.

    In this article, the free field theory limit of operators dual to giant gravitons with open strings attached are studied. We introduce a graphical notation, which employs Young diagrams, for these operators. The computation of two point correlation functions is reduced to the application of three simple rules, written as graphical operations performed on the Young diagram labels of the operators. Using this technology, we have studied gravitational radiation by giant gravitons and bound states of giant gravitons, transitions between excited giant graviton states and joining of open strings attached to the giant.

    2003-05-01

    In a combined experimental and theoretical effort, we have investigated attachment and vibrational excitation in low-energy electron collisions with chlorine molecules. Using the laser photoelectron attachment method, we have measured the energy dependence of the cross section for dissociative electron attachment (Cl^- formation) over the range 0 - 195 meV with an energy width of 1-3 meV. Near zero energy, the cross section shows a behavior compatible with the threshold law for p-wawe attachment via the ^2?_u^+ resonance, reaches a maximum around 50 meV and declines towards higher energies. These findings are in very good agreement with the results of semiempirical R-matrix calculations. The latter are extended to describe attachment through the ^2?g and ^2?u resonances, and recommended absolute cross sections for dissociative attachment to chlorine molecules at room temperature are provided over the energy range 0 - 9 eV. Furthermore, we predict cross sections for vibrationally inelastic scattering through the ^2?_u^+, ^2?_g, and ^2?u resonances.

  6. The role of attachment styles in regulating the effects of dopamine on the behavior of salespersons

    2014-01-01

    Two classic strategic orientations have been found to pervade the behavior of modern salespersons: a sales orientation (SO) where salespersons use deception or guile to get customers to buy even if they do not need a product, and a customer orientation (CO) where salespersons first attempt to discover the customer's needs and adjust their product and selling approach to meet those needs. Study 1 replicates recent research and finds that the Taq A1 variant of the DRD2 gene is not related to either sales or CO, whereas the 7-repeat variant of the DRD4 gene is related to CO but not SO. Study 2 investigates gene × phenotype explanations of orientation of salespersons, drawing upon recent research in molecular genetics and biological/psychological attachment theory. The findings show that attachment style regulates the effects of DRD2 on CO, such that greater avoidant attachment styles lead to higher CO for persons with the A2/A2 variant but neither the A1/A2 nor A1/A1 variants. Likewise, attachment style regulates the effects of DRD4 on CO, such that greater avoidant attachment styles lead to higher CO for persons with the 7-repeat variant but not other variants. No effects were found on a SO, and secure and anxious attachment styles did not function as moderators. PMID:24550811

    Contamination of industrial and domestic food usage environments by the attachement of bacterial food-borne pathogen Listeria monocytogenes has public health and economic implications. Comprehensive proteomics experiments using label-free liquid chromatography/tandem mass spectrometry were used to compare the proteomes of two different L. monocytogenes strains (Siliken_1/2c and F2365_4b), which show very different capacities to attach to surfaces. Growth temperature and strain type were highly influential on the proteomes in both attached and planktonic cells. On the basis of the proteomic data, it is highly unlikely that specific surface proteins play a direct role in adherence to inanimate surfaces. Instead, strain-dependent responses related to cell envelope polymer biosynthesis and stress response regulation likely contribute to a different ability to attach and also to survive external stressors. Collectively, the divergent proteome-level responses observed define strain- and growth-temperature-dependent differences relevant to attachment efficacy, highlight relevant proteins involved in stress protection in attached cells, and suggest that strain differences and growth conditions are important in relation to environmental persistence.

    Modeling surface water Escherichia coli fate and transport requires partitioning E. coli into particle-attached and unattached fractions. Attachment is often assumed to be a constant fraction or is estimated using simple linear models. The objectives of this study were to: (i) develop statistical models for predicting E. coli attachment and virulence marker presence in fluvial systems, and (ii) relate E. coli attachment to a variety of environmental parameters. Stream water samples (n = 60) were collected at four locations in a rural, mixed-use watershed between June and October 2012, with four storm events (>20 mm rainfall) being captured. The percentage of E. coli attached to particles (>5 ?m) and the occurrences of virulence markers were modeled using water quality, particle concentration, particle size distribution, hydrology and land use factors as explanatory variables. Three types of statistical models appropriate for highly collinear, multidimensional data were compared: least angle shrinkage and selection operator (LASSO), classification and regression trees using the general, unbiased, interaction detection and estimation (GUIDE) algorithm, and multivariate adaptive regression splines (MARS). All models showed that E. coli particle attachment and the presence of E. coli virulence markers in the attached and unattached states were influenced by a combination of water quality, hydrology, land-use and particle properties. Model performance statistics indicate that MARS models outperform LASSO and GUIDE models for predicting E. coli particle attachment and virulence marker occurrence. Validating the MARS modeling approach in multiple watersheds may allow for the development of a parameterizing model to be included in watershed simulation models. PMID:24075474

    Adult attachment style refers to individual personality traits that strongly influence emotional bonds and reactions to social partners. Behavioral research has shown that adult attachment style reflects profound differences in sensitivity to social signals of support or conflict, but the neural substrates underlying such differences remain unsettled. Using functional magnetic resonance imaging (fMRI), we examined how the three classic prototypes of attachment style (secure, avoidant, anxious) modulate brain responses to facial expressions conveying either positive or negative feedback about task performance (either supportive or hostile) in a social game context. Activation of striatum and ventral tegmental area was enhanced to positive feedback signaled by a smiling face, but this was reduced in participants with avoidant attachment, indicating relative impassiveness to social reward. Conversely, a left amygdala response was evoked by angry faces associated with negative feedback, and correlated positively with anxious attachment, suggesting an increased sensitivity to social punishment. Secure attachment showed mirror effects in striatum and amygdala, but no other specific correlate. These results reveal a critical role for brain systems implicated in reward and threat processing in the biological underpinnings of adult attachment style, and provide new support to psychological models that have postulated two separate affective dimensions to explain these individual differences, centered on the ventral striatum and amygdala circuits, respectively. These findings also demonstrate that brain responses to face expressions are not driven by facial features alone but determined by the personal significance of expressions in current social context. By linking fundamental psychosocial dimensions of adult attachment with brain function, our results do not only corroborate their biological bases but also help understand their impact on behavior.

    Cartilage oligomeric matrix protein/thrombospondin 5 (COMP/TSP5) is a major component of the extracellular matrix of the musculoskeletal system. Although COMP/TSP5 abnormalities are associated with several pathological conditions, its normal function remains unclear. This study was undertaken to delineate the function(s) of COMP/TSP5 in cartilage, especially regarding its interaction with chondrocytes. We show that COMP/TSP5 can support chondrocyte attachment and that the RGD sequence in COMP/TSP5 and the integrin receptors ?5?1 and ?V?3 on the chondrocytes are involved in mediating this attachment. The interactions of COMP/TSP5 with the integrins are dependent on COMP/TSP5 conformation. Chondrocyte attachment to COMP/TSP5 in the calcium-replete conformation was inhibited by function-blocking integrin ?5 and ?1 antibodies, suggesting the involvement of the ?5?1 integrin. Under this condition, a function-blocking antibody against ?V?3 did not have any effect on cell attachment. On the other hand, chondrocyte attachment to reduced COMP/TSP5 was instead sensitive to ?V?3 function-blocking antibodies, suggesting that COMP/TSP5 mediates attachment through chondrocyte ?V?3 integrin under this condition. Cell attachment to reduced COMP/TSP5 was not inhibited by ?1 antibodies. These data indicate that COMP/TSP5 in different conformations can utilize different integrin receptors. These results are the first to demonstrate that COMP/TSP5 can mediate chondrocyte attachment through interactions with integrins. Through these interactions, COMP/TSP5 may be able to regulate cellular activities and respond to environment in the surrounding cartilage matrix. PMID:16051604

Secure adolescents reconstructed interactions with each parent more favorably over time, whereas insecure adolescents showed less favorable reconstructive memory. Likewise, mothers of secure girls reconstructed conflicts more favorably over time, whereas mothers of insecure boys showed less favorable reconstructive memory. Participant ratings were associated with observational ratings in theoretically consistent ways. Contrary to expectations, fathers showed no attachment-related memory biases. PMID:20840233

    Attachment researchers have proposed that the attachment, caregiving, and sexual behavioral systems are interrelated in adult love relationships (Mikulincer & Shaver, 2007 ). This study examined whether aspects of partners' caregiving (proximity, sensitivity, control, compulsive caregiving) mediated the association between their attachment insecurities (anxiety and avoidance) and each other's sexual satisfaction in two samples of committed couples (Study 1: 126 cohabiting or married couples from the general community; Study 2: 55 clinically distressed couples). Partners completed the Experiences in Close Relationships measure (Brennan, Clark, & Shaver, 1998 ), the Caregiving Questionnaire (Kunce & Shaver, 1994 ), and the Global Measure of Sexual Satisfaction (Lawrance & Byers, 1998 ). Path analyses based on the actor-partner interdependence model (APIM) revealed that caregiving proximity mediated the association between low attachment avoidance and partners' sexual satisfaction in distressed and nondistressed couples. Sensitivity mediated this association in nondistressed couples only. Control mediated the association between men's insecurities (attachment-related avoidance and anxiety) and their partners' low sexual satisfaction in nondistressed couples. Attachment anxiety predicted compulsive caregiving, but this caregiving dimension was not a significant mediator. These results are discussed in light of attachment theory and their implications for treating distressed couples. PMID:23659357

    Many scholars have proposed that parent-child attachment security should favor child sleep. Research has yet, however, to provide convincing support for this hypothesis. The current study used objective measures of sleep and attachment to assess the longitudinal links between mother-child attachment security and subsequent sleep, controlling for child dependency. Sixty-two middle-class families (30 girls) were met twice, when children were 15 months (Wave 1; W1) and 2 years of age (Wave 2; W2). At W1, mother-child attachment was assessed with the observer version of the Attachment Q-Sort. At W2, children wore an actigraph monitor for 72?hr. Results indicated that children more securely attached to their mothers subsequently slept more at night and had higher sleep efficiency, and these predictions were not confounded by child dependency. These findings suggest a unique role for secure attachment relationships in the development of young children's sleep regulation, while addressing methodological issues that have long precluded consensus in this literature.

    The associations between attachment representations of adopted young adults and their experiential and physiological arousal to infant crying were examined. Attachment representations were assessed with the Attachment Script Assessment (ASA), and the young adults listened to infant cries, during which ratings of cry perception were collected and physiological reactivity was measured. Secure adoptees showed a well-integrated response to infant distress: heart-rate increases and respiratory sinus arrhythmia (RSA) withdrawal were coupled with heightened perception of urgency in these individuals. In insecure adoptees RSA withdrawal was absent, and a combination of lowered perceived urgency and heightened sympathetic arousal was found, reflecting a deactivating style of emotional reactivity. Overall, our findings support the idea that internal working models of attachment explain individual differences in the way attachment-related information is processed. PMID:25460537

    The authors present an integrative account of how attachment insecurities relate to sexism. Two studies showed that attachment avoidance predisposes men to endorse hostile but to reject benevolent sexism (BS), whereas attachment anxiety predisposes men toward ambivalent (both hostile and benevolent) sexism. The authors also tested predicted mediators, finding that men's social dominance orientation (a competitive intergroup ideology) mediated the avoidance to hostile sexism link. In addition, romanticism (an idealized interpersonal ideology) mediated attachment insecurity to BS links: (a) Avoidant men tended to reject romanticism (i.e., were cynical about romance) and, in turn, were likely to reject BS, whereas (b) anxious men tended to endorse romanticism (i.e., were idealistic about romance) and, in turn, likely to endorse BS. The authors conclude that men's sexism stems in part from dispositional attachment working models, both directly and through the interpersonal and intergroup ideologies they generate. PMID:22854788

    This research examines the significance of the survivor-victim relationship in understanding grief following sudden death bereavement. Data for this study come from medical examiner's reports and mailed self-report surveys of survivors of suicide and accidental death. In general, the results show that survivor-victim attachment is more important than survivor's status in explaining grief reactions. Also, suicide survivors experience significantly less emotional distress and shock, but greater feelings of guilt/shame and rejection, than survivors of accidental death. This paper concludes by directing future research to explore more fully the importance of survivor-victim relationships in understanding grief following bereavement. PMID:1799019

    Summary The impeding effect of plant surfaces covered with three-dimensional wax on attachment and locomotion of insects has been shown previously in numerous experimental studies. The aim of this study was to examine the effect of different parameters of crystalline wax coverage on insect attachment. We performed traction experiments with the beetle Coccinella septempunctata and pull-off force measurements with artificial adhesive systems (tacky polydimethylsiloxane semi-spheres) on bioinspired wax surfaces formed by four alkanes of varying chain lengths (C36H74, C40H82, C44H90, and C50H102). All these highly hydrophobic coatings were composed of crystals having similar morphologies but differing in size and distribution/density, and exhibited different surface roughness. The crystal size (length and thickness) decreased with an increase of the chain length of the alkanes that formed these surfaces, whereas the density of the wax coverage, as well as the surface roughness, showed an opposite relationship. Traction tests demonstrated a significant, up to 30 fold, reduction of insect attachment forces on the wax surfaces when compared with the reference glass sample. Attachment of the beetles to the wax substrates probably relied solely on the performance of adhesive pads. We found no influence of the wax coatings on the subsequent attachment ability of beetles. The obtained data are explained by the reduction of the real contact between the setal tips of the insect adhesive pads and the wax surfaces due to the micro- and nanoscopic roughness introduced by wax crystals. Experiments with polydimethylsiloxane semi-spheres showed much higher forces on wax samples when compared to insect attachment forces measured on these surfaces. We explain these results by the differences in material properties between polydimethylsiloxane probes and tenent setae of C. septempunctata beetles.

    The impeding effect of plant surfaces covered with three-dimensional wax on attachment and locomotion of insects has been shown previously in numerous experimental studies. The aim of this study was to examine the effect of different parameters of crystalline wax coverage on insect attachment. We performed traction experiments with the beetle Coccinella septempunctata and pull-off force measurements with artificial adhesive systems (tacky polydimethylsiloxane semi-spheres) on bioinspired wax surfaces formed by four alkanes of varying chain lengths (C36H74, C40H82, C44H90, and C50H102). All these highly hydrophobic coatings were composed of crystals having similar morphologies but differing in size and distribution/density, and exhibited different surface roughness. The crystal size (length and thickness) decreased with an increase of the chain length of the alkanes that formed these surfaces, whereas the density of the wax coverage, as well as the surface roughness, showed an opposite relationship. Traction tests demonstrated a significant, up to 30 fold, reduction of insect attachment forces on the wax surfaces when compared with the reference glass sample. Attachment of the beetles to the wax substrates probably relied solely on the performance of adhesive pads. We found no influence of the wax coatings on the subsequent attachment ability of beetles. The obtained data are explained by the reduction of the real contact between the setal tips of the insect adhesive pads and the wax surfaces due to the micro- and nanoscopic roughness introduced by wax crystals. Experiments with polydimethylsiloxane semi-spheres showed much higher forces on wax samples when compared to insect attachment forces measured on these surfaces. We explain these results by the differences in material properties between polydimethylsiloxane probes and tenent setae of C. septempunctata beetles. Among wax surfaces, force experiments showed stronger insect attachment and higher pull-off forces of polydimethylsiloxane probes on wax surfaces having a higher density of wax coverage, created by smaller crystals.

    In a longitudinal study with 125 early adopted adolescents, we examined continuity of attachment from infancy to adolescence and the role of parental sensitive support in explaining continuity or discontinuity of attachment. Assessments of maternal sensitive support and infant attachment (Strange Situation Procedure) were completed when infants were 12 months old. When the children were 14 years old, we observed mothers' sensitive support during a conflict discussion. The adolescents' attachment representations were assessed with the Adult Attachment Interview. Mothers of secure adolescents showed significantly more sensitive support during conflicts than did mothers of insecure adolescents. Overall, no continuity of attachment from infancy to adolescence was found. However, maternal sensitive support in early childhood and adolescence predicted continuity of secure attachment from 1 to 14 years, whereas less maternal sensitive support in early childhood but more maternal sensitive support in adolescence predicted children's change from insecurity in infancy to security in adolescence. We conclude that both early and later parental sensitive support are important for continuity of attachment across the first 14 years of life. PMID:22369333

    In this paper, we present an investigation into the effects of surface topography (roughness) and hydrophobicity (contact angle measurement) on bacteria adhesion for polystyrene materials. The surfaces of polystyrene substrates were patterned using UV-laser radiation with a wavelength of 193 nm under different conditions. Various surface topographies were fabricated and were measured by an optical surface profiler and contact angle measurements were recorded. For the bacterial adhesion experiments, an assay of Escherichia coli (E. coli) was developed and used for measurements on both as-received and modified polystyrene surfaces. The method is based on the staining of attached bacterial cells with the nucleic acid-binding, green fluorescent DAPI (4?, 6-diamidino-2-phenylindole) stain. The preliminary results show that laser-assisted modification induced by laser ablation can make polystyrene substrates either more hydrophilic (with oxygen) or more hydrophobic (with air). The contact angle can be varied from 37° to 108°. The results on bacterial attachment show that the polystyrene substrates as received have no bacteria attached, indicating a good anti-bacterial performance. The treated substrates show some bacterial attachment and, in particular, the surfaces with a high contact angle have much higher numbers of bacterial cells attached. This indicates that such a laser-assisted process with air can make polystyrene surfaces more attractive to E. coli bacteria.

    Rate constants have been measured from 300 to 700 K for thermal electron attachment to F2 using two flowing afterglow-Langmuir probe apparatuses. Dissociative attachment yielding F- is observed with a rate constant of 5.0 ± 1.3 × 10-9 cm3 s-1 at 300 K, rising to 9.6 ± 2.4 × 10-9 cm3 s-1 at 700 K, well below the previously accepted values of McCorkle [D. L. McCorkle, L. G. Christophorou, A. A. Christodoulides, and L. Pichiarella, J. Chem. Phys.JCPSA60021-960610.1063/1.451139 85, 1966 (1986)]. The absolute concentration of F2 reaching the afterglow is verified by measuring the near-collisional rate constant (4.5 ± 1.5 × 10-10 cm3 s-1) for Ar+ + F2?ArF+ + F. Prior attempts to apply R-matrix calculations to the F2 + e- system have failed to explain previously reported thermal and nonthermal attachment rate constants along with high-resolution, low-energy attachment cross sections. The present results are reproduced exceptionally well by R-matrix calculations employing previously calculated resonance widths without adjustment.

    This paper suggests that the behaviours associated with the formal diagnosis of the "disinhibited" form of reactive attachment disorder (RAD) might be seen as a functional adaptation rather than a mental health problem, a facultative response enhancing the probability of survival that is triggered by certain conditions. Although disinhibited RAD is most commonly observed in institutionalised children, similar behaviours may also be a part of the emotional difficulties displayed by some fostered and adopted children (the latter includes those once institutionalised), and these may demonstrate not so much a discrete attachment disorder as either the need to fend for oneself following loss of dedicated caregiving or a lack of opportunity to build specific intimate relationships with dedicated caregivers. In many cases this may be inextricably mixed with the neurobiological and psychological seqelae of maltreatment. Indiscriminate attachment behaviour, from this proposed evolutionary perspective, is less a syndrome of mental ill-health than an astute survival manoeuvre following being orphaned, abandoned or fecklessly reared. Such a response, allied to the innate facility to access caregiving from different adults, could be expected to be initiated by specific events as are the other attachment configurations. Classing disinhibited RAD as an adaptation has implications for helping children brought up under extreme duress when their caregiving environment has changed for the better. PMID:20473797

Growth and survival of the microbial community or biofilm then depends on adaptation to a series of changing environmental milieux. Within the realm of cell—cell interaction, recent advances suggest that flagella, fimbriae and other protein receptors are essential for bacterial attachment to surfaces.

    The thermal and solvent tolerance of enzymes is highly important for their industrial use. We show here that the enzyme lipase from Rhizopus oryzae exhibits exceptionally high thermal stability and high solvent tolerance and even increased activity in acetone when immobilized onto a graphene oxide (GO) nanosupport prepared by Staudenmaier and Brodie methods. We studied various forms of immobilization of the enzyme: by physical adsorption, covalent attachment, and additional crosslinking. The activity recovery was shown to be dependent on the support type, enzyme loading and immobilization procedure. Covalently immobilized lipase showed significantly better resistance to heat inactivation (the activity recovery was 65% at 70 °C) in comparison with the soluble counterpart (the activity recovery was 65% at 40 °C). Physically adsorbed lipase achieved over 100% of the initial activity in a series of organic solvents. These findings, showing enhanced thermal stability and solvent tolerance of graphene oxide immobilized enzyme, will have a profound impact on practical industrial scale uses of enzymes for the conversion of lipids into fuels.The thermal and solvent tolerance of enzymes is highly important for their industrial use.

    Recently studies examining the colonization of Clostridial pathogens on agar and human tissue culture cells, demonstrated that (C. sporogenes ATCC 3584, C. difficile ATCC 43594 [patient isolate], C. difficile ATCC 9689 [non-clinical], C. clostridioforme [patient isolate]) bacterial spores (endospores) of the genus Clostridia have an outer membrane that becomes responsive at activation and exhibits extensions of the exosporial membrane that facilitate and maintain spore attachment to a nutritive substrate during germination and initial outgrowth of the newly developed bacterial cell. Therefore this attachment phenomenon plays an important role in insuring bacterial colonization of a surface and the initial stages of the infective process. To see if other non-clinical members of this genus also have this ability to attach to a substrate or food-source during spore germination, and how this attachment process in environmental thermophiles compares to the clinical paradigm (in relation to time sequence, exosporial membrane structure, type of attachment structures, composition of the membrane etc...), sediment samples were collected in sterile transport containers at 4 geothermal sites at Yellowstone National Park in Wyoming. Because spore forming bacteria will produce spores when conditions are unfavorable for growth, the samples were sealed and stored at 4 C. After 8 months the samples were screened for the presence of spores by light microscope examination using malachite green/safranin, and traditional endospores were identified in significant quantities from the Terrace Spring site (a 46 C lake with bacterial mats and a rapidly moving run-off channel leading to a traditional hot spring). The highest spore population was found in the top sediment and benthic water of the run-off channel, pH 8.1.

  15. The statistical behaviour of attached eddies

    NASA Astrophysics Data System (ADS)

    Woodcock, J. D.; Marusic, I.

    2015-01-01

    Townsend's attached eddy hypothesis forms the basis of an established model of the logarithmic layer in wall-bounded turbulent flows in which this inertially dominated region is characterised by a hierarchy of geometrically self-similar eddying motions that scale with their distance to the wall. The hypothesis has gained considerable support from high Reynolds number measurements of the second-order moments of the fluctuating velocities. Recently, Meneveau and Marusic ["Generalized logarithmic law for high-order moments in turbulent boundary layers," J. Fluid Mech. 719, R1 (2013)] presented experimental evidence that all even-ordered moments of the streamwise velocity will exhibit a logarithmic dependence on the distance from the wall. They demonstrated that this was consistent with the attached eddy hypothesis, so long as the velocity distribution is assumed to be Gaussian (which allows the use of the central limit theorem). In this paper, we derive this result from the attached eddy model without assuming a Gaussian velocity distribution, and find that such logarithmic behaviours are valid in the large Reynolds number limit. We also revisit the physical and mathematical basis of the attached eddy hypothesis, in order to increase rigour and minimise the assumptions required to apply the hypothesis. To this end, we have extended the proof of Campbell's theorem to apply to the velocity field corresponding to a forest of variously sized eddies that are randomly placed on the wall. This enables us to derive all moments of the velocity in the logarithmic region, including cross-correlations between different components of the velocity. By contrast, previous studies of the attached eddy hypothesis have considered only the mean velocity and its second order moments. From this, we obtain qualitatively correct skewnesses and flatnesses for the spanwise and wall-normal fluctuations. The issue of the Reynolds number dependence of von Kármán's constant is also addressed.

    1998-01-01

    Experimental analysis of the sedimentation velocity of Cryptosporidium parvum oocysts and Giardia lamblia cysts was compared with mathematical description of their sedimentation velocities by using measurements of (oo)cyst size and density and the density and viscosity of the sedimentation medium to determine if the sedimentation kinetics of freely suspended oocysts of C. parvum and cysts of G. lamblia can be described by Stokes’ law. The theoretically calculated sedimentation kinetics showed a good agreement with the experimentally observed kinetics. Both showed a decline in sedimentation velocity over time, caused primarily by variation in (oo)cyst density. The initial apparent sedimentation velocities in Hanks balanced salt solution at 23°C was 0.35 ?m · s?1 for oocysts and 1.4 ?m · s?1 for cysts. (Oo)cysts that enter the surface water environment by discharges of biologically treated sewage may be attached to sewage particles, and this will affect their sedimentation kinetics. Therefore, (oo)cysts were mixed with settled secondary effluent. (Oo)cysts readily attached to the (biological) particles in effluent; 30% of both cysts and oocysts attached during the first minutes of mixing, and this fraction increased to approximately 75% after 24 h. The sedimentation velocity of (oo)cysts attached to secondary effluent particles increased with particle size and was (already in the smallest size fraction [1 to 40 ?m]) determined by the sedimentation kinetics of the effluent particles. The observed sedimentation velocities of freely suspended (oo)cysts are probably too low to cause significant sedimentation in surface water or reservoirs. However, since a significant proportion of both cysts and oocysts attached readily to organic biological particles in secondary effluent, sedimentation of attached (oo)cysts after discharge into surface water will probably be a significant factor in the environmental ecology of C. parvum and G. lamblia. Attachment to particles influences not only sedimentation of (oo)cysts in surface water but also their behavior in drinking water treatment processes. PMID:9797307

    The primary aim of this article was to demonstrate the clinical utility of an empirically grounded perspective on the complex interplay between patients' attachment style and their ability to create, remember, and use benignly influential representations of their experiences with their therapists. We focused on 2 interrelated questions: Are there significant attachment-related differences in the thematic content of the remembrances and fantasies that patients have about therapy? And, if so, what are the implications for practice? Results of a study of individuals currently in therapy (N = 176) indicated that although all the patients with different insecure attachment styles struggled to evoke positively valenced therapist representations, the specific nature of their representational patterns varied as a function of specific attachment styles. We offer several clinical strategies that may increase insecure patients' abilities to form adaptive representations of their therapist and therapy. We illustrate our recommendations by presenting case material from the psychotherapy of a compulsively self-reliant man. PMID:25833756

    From the National Library of Canada, this entertaining site takes the user page-by-page through the creation of a picture book, Zoom Upstream, written by Tim Wynne-Jones and illustrated by Eric Beddows. Zoom Upstream is the third book chronicling the adventures of Zoom the cat; in this one he visits Egypt. The eight main sections of the site, in either French or English, trace the book's progress from idea through finding the illustrator and pictures, to printing, selling the book, and afterwards. The section on pictures, appropriately, is the most extensive, showing how the illustrator gets every detail exactly right, beginning with analyzing the text for words and concepts that need to be represented in the pictures. To get the characters to look right, Beddows made a cat model and photographed human models in scenes from the book. For backgrounds, the illustrator studied books on Egyptian architecture, and made a research trip to Egypt. Wynne-Jones, the author, does admit that writing the first Zoom book (Zoom at Sea) only took 20 minutes, but that "usually writing a story is a lot harder".

  12. Vibrio cholerae use pili and flagella synergistically to effect motility switching and conditional surface attachment

    Utada, Andrew S.; Bennett, Rachel R.; Fong, Jiunn C. N.; Gibiansky, Maxsim L.; Yildiz, Fitnat H.; Golestanian, Ramin; Wong, Gerard C. L.

    2014-09-01

    We show that Vibrio cholerae, the causative agent of cholera, use their flagella and mannose-sensitive hemagglutinin (MSHA) type IV pili synergistically to switch between two complementary motility states that together facilitate surface selection and attachment. Flagellar rotation counter-rotates the cell body, causing MSHA pili to have periodic mechanical contact with the surface for surface-skimming cells. Using tracking algorithms at 5?ms resolution we observe two motility behaviours: ‘roaming', characterized by meandering trajectories, and ‘orbiting’, characterized by repetitive high-curvature orbits. We develop a hydrodynamic model showing that these phenotypes result from a nonlinear relationship between trajectory shape and frictional forces between pili and the surface: strong pili–surface interactions generate orbiting motion, increasing the local bacterial loiter time. Time-lapse imaging reveals how only orbiting mode cells can attach irreversibly and form microcolonies. These observations suggest that MSHA pili are crucial for surface selection, irreversible attachment, and ultimately microcolony formation.

    2002-06-01

    Carboxy ion (COOH +) implantation was performed at the energy of 50 keV with fluences ranging from 1×10 14 to 1×10 15 ions/cm 2 at room temperature for polypropylene (PP). The effects of ion implantation on cells (immune macrophages, 3T3 mouse fibroblasts and human endothelial cells) were studied in vitro. Tests of cell attachment gave interesting results that the 3T3 mouse fibroblasts and human endothelial cells cultured on the surface of the implanted PP showed much better attachment and proliferation than that on pristine PP. At the same time, the COOH + ion implantation also induced low macrophage attachment with normal cellular morphology. Results of X-ray photoelectron spectroscopy (XPS) and Fourier-transform infrared (FTIR) analysis showed that COOH + ion implantation caused the rearrangement of chemical bonds and the formation of some new O-containing groups, which was responsible for the enhancement of the biocompatibility of PP.

    1990-01-01

    Vibrio cholerae serogroup O1, the causative agent of cholera, is capable of surviving in aquatic environments for extended periods and is considered an autochthonous species in estuarine and brackish waters. These environments contain numerous elements that may affect its ecology. The studies reported here examined physical interactions between V. cholerae O1 and natural plankton populations of a geographical region in Bangladesh where cholera is an endemic disease. Results showed that four of five clinical V. cholerae O1 strains and endogenous bacterial flora were attached preferentially to zooplankton molts (exuviae) rather than to whole specimens. One strain attached in approximately equal numbers to both exuviae and whole specimens. V. cholerae O1 also attached to several phytoplankton species. The results show that V. cholerae O1 can bind to diverse plankton species collected from an area where cholera is an endemic disease, with potentially significant effects on its ecology.

    Previous research suggested that 16-week old dog pups, but not wolf pups, show attachment behaviour to a human caregiver. Attachment to a caregiver in dog pups has been demonstrated by differential responding to a caregiver compared to a stranger in the Ainsworth Strange Situation Test. We show here that 3-7 week old wolf pups also show attachment-like behaviour to a human caregiver as measured by preferential proximity seeking, preferential contact, and preferential greeting to a human caregiver over a human stranger in a modified and counterbalanced version of the Ainsworth Strange Situation Test. In addition, our results show that preferential responding to a caregiver over a stranger is only apparent following brief isolation. In initial episodes, wolf pups show no differentiation between the caregiver and the stranger; however, following a 2-min separation, the pups show proximity seeking, more contact, and more greeting to the caregiver than the stranger. These results suggest intensive human socialization of a wolf can lead to attachment--like responding to a human caregiver during the first two months of a wolf pup's life. PMID:25447510

    A review was conducted of 14 studies published from 1995 to 2013 and 2 thus far unpublished studies that have used the Client Attachment to Therapist Scale (CATS) in research with help-seeking clients. Of these, meta-analyses were conducted for studies that examined the CATS subscales (Secure, Avoidant, Preoccupied) as correlates of client-rated working alliance, client pretherapy general adult attachment, or both (Total k = 13; k = 9 for each specific analysis). With regard to pretherapy adult attachment, CATS Secure was negatively associated with client Anxiety and Avoidance. For CATS Avoidant, clients' attachment avoidance and anxiety were positively associated. For CATS Preoccupied, client adult attachment Anxiety was significantly positively associated. CATS Secure was strongly positively correlated with total working alliance, CATS Avoidant was negatively correlated with total working alliance, and CATS Preoccupied was not significantly associated with working alliance. Implications for models of therapeutic change based on client gains in social competencies and capacity for secure attachment are discussed.

  17. Chiasmata Promote Monopolar Attachment of Sister Chromatids and Their Co-Segregation toward the Proper Pole during Meiosis I

    The chiasma is a structure that forms between a pair of homologous chromosomes by crossover recombination and physically links the homologous chromosomes during meiosis. Chiasmata are essential for the attachment of the homologous chromosomes to opposite spindle poles (bipolar attachment) and their subsequent segregation to the opposite poles during meiosis I. However, the overall function of chiasmata during meiosis is not fully understood. Here, we show that chiasmata also play a crucial role in the attachment of sister chromatids to the same spindle pole and in their co-segregation during meiosis I in fission yeast. Analysis of cells lacking chiasmata and the cohesin protector Sgo1 showed that loss of chiasmata causes frequent bipolar attachment of sister chromatids during anaphase. Furthermore, high time-resolution analysis of centromere dynamics in various types of chiasmate and achiasmate cells, including those lacking the DNA replication checkpoint factor Mrc1 or the meiotic centromere protein Moa1, showed the following three outcomes: (i) during the pre-anaphase stage, the bipolar attachment of sister chromatids occurs irrespective of chiasma formation; (ii) the chiasma contributes to the elimination of the pre-anaphase bipolar attachment; and (iii) when the bipolar attachment remains during anaphase, the chiasmata generate a bias toward the proper pole during poleward chromosome pulling that results in appropriate chromosome segregation. Based on these results, we propose that chiasmata play a pivotal role in the selection of proper attachments and provide a backup mechanism that promotes correct chromosome segregation when improper attachments remain during anaphase I.

    The mucosal attachment pattern of Corynosoma australe in the intestines of Arctocephalus australis is described. Normal and abnormal tissue were sampled from 32 hosts to be submitted to histological routine protocol to embedding in paraffin and permanent mounting in balsam. Corynosoma australe shows three different degrees of body depth intestinal attachment (BDINA-1-3). BDINA-1: it is exclusive of the small intestine and the parasite attaches on the villi; BDINA-2: parasite affects the Lieberkühn crypts in several depth levels and, BDINA-3: the parasite reaches the submucosa. These attachment patterns alter the mucosa by degeneration and dysfunction due to necrosis of mucosal structure, great quantities of cellular debris and significant reduction of the mucosal thickness. Other aspects are crater-like concave holes (CLCHs) as sites where C. australe could be attached-detached several times according to adult migratory processes within luminal intestine space. The submucosa shows edema probably due to the local mucosal alterations resulting in homeostatic break. There is no severe inflammatory response by host but BDINA-1 to BDINA-3 and CLCH could represent foci to secondary opportunistic infections and significant areas of malabsorption in severally infected hosts contributing to increase clinical signs of preexistent pathologies.

    2013-03-01

    Iron nanoparticles were used as a test system to explore the functionalization and attachment of magnetic nanoparticles with two different functionalities through ``click chemistry.'' Two different samples of iron nanoparticles were modified with 5-azidopentanoic acid and with 5-hexynoic acid, respectively. This modification was followed by click chemistry to change the morphology of agglomeration. A combination of density functional theory calculations, Fourier-transform infrared spectroscopy, and X-ray photoelectron spectroscopy was used to monitor each step of the process. Spectroscopies confirmed the success and completion of click reaction. Scanning electron microscopy images showed the change in size and morphology of the iron nanoparticles before and after click chemistry. Vibrating sample magnetometer study showed the majority of the magnetic properties were retained following functionalization and click reaction. Exploring similar approach for two types of materials with functionalization and attachment of hard magnetic materials and soft magnetic materials will be presented based on our initial studies of SmCo nanoparticles in a combination with iron nanoparticles.

  6. Attaching Thermocouples by Peening or Crimping

    NASA Technical Reports Server (NTRS)

    Murtland, Kevin; Cox, Robert; Immer, Christopher

    2006-01-01

    Two simple, effective techniques for attaching thermocouples to metal substrates have been devised for high-temperature applications in which attachment by such conventional means as welding, screws, epoxy, or tape would not be effective. The techniques have been used successfully to attach 0.005- in. (0.127-mm)-diameter type-S thermocouples to substrates of niobium alloy C-103 and stainless steel 416 for measuring temperatures up to 2,600 F (1,427 C). The techniques are equally applicable to other thermocouple and substrate materials. In the first technique, illustrated in the upper part of the figure, a hole slightly wider than twice the diameter of one thermocouple wire is drilled in the substrate. The thermocouple is placed in the hole, then the edge of the hole is peened in one or more places by use of a punch (see figure). The deformed material at the edge secures the thermocouple in the hole. In the second technique a hole is drilled as in the first technique, then an annular relief area is machined around the hole, resulting in structure reminiscent of a volcano in a crater. The thermocouple is placed in the hole as in the first technique, then the "volcano" material is either peened by use of a punch or crimped by use of sidecutters to secure the thermocouple in place. This second technique is preferable for very thin thermocouples [wire diameter .0.005 in. (.0.127 mm)] because standard peening poses a greater risk of clipping one or both of the thermocouple wires. These techniques offer the following advantages over prior thermocouple-attachment techniques: . Because these techniques involve drilling of very small holes, they are minimally invasive . an important advantage in that, to a first approximation, the thermal properties of surrounding areas are not appreciably affected. . These techniques do not involve introduction of any material, other than the substrate and thermocouple materials, that could cause contamination, could decompose, or oxidize at high measurement temperatures. . The simplicity of these techniques makes it possible to attach thermocouples quickly. . These techniques can be used to attach thermocouples at locations where access is somewhat restricted by the surrounding objects.

    The thermal and solvent tolerance of enzymes is highly important for their industrial use. We show here that the enzyme lipase from Rhizopus oryzae exhibits exceptionally high thermal stability and high solvent tolerance and even increased activity in acetone when immobilized onto a graphene oxide (GO) nanosupport prepared by Staudenmaier and Brodie methods. We studied various forms of immobilization of the enzyme: by physical adsorption, covalent attachment, and additional crosslinking. The activity recovery was shown to be dependent on the support type, enzyme loading and immobilization procedure. Covalently immobilized lipase showed significantly better resistance to heat inactivation (the activity recovery was 65% at 70 °C) in comparison with the soluble counterpart (the activity recovery was 65% at 40 °C). Physically adsorbed lipase achieved over 100% of the initial activity in a series of organic solvents. These findings, showing enhanced thermal stability and solvent tolerance of graphene oxide immobilized enzyme, will have a profound impact on practical industrial scale uses of enzymes for the conversion of lipids into fuels.
