In Idiopathic Calcium Oxalate Stone Formers, Unattached Stones Show Evidence of Having Originated as Attached Stones on Randall's Plaque  

PubMed Central

Objective To analyze the structure and composition of unattached stones in idiopathic calcium oxalate stone formers (ICSF) and compare them to attached stones from the same cohort in order to investigate whether more than one pathogenic mechanism exists for stone formation in ICSF. Patients and methods ICSF undergoing percutaneous nephrolithotomy or ureteroscopy for treatment of nephrolithiasis were consented for this study. All accessible renal papillae were endoscopically imaged using a digital endoscope. All stones were removed and determined by the operating surgeon to be attached or unattached to the underlying papilla. Micro-computed tomography (micro-CT), which provides three-dimensional analysis of entire stones, was used to compare the structure and composition of attached versus unattached stones. Results Of 115 stones collected from 9 patients (12 renal units), only 25 stones were found not to be attached to renal papillae. Of these 25 stones, 4 were lost and 12 showed definite morphological evidence of having been attached to tissue, probably having been knocked off of papillae during access. For the remaining 9 stones, micro-CT analysis revealed at least one internal region of calcium phosphate within each of these unattached calcium oxalate (CaOx) stones. That is, the internal structure of the unattached stones is consistent with their having originated attached to RP, and then having become detached but retained in the kidney, with new layers of CaOx eventually covering the original attachment site. Conclusions Micro CT analysis supports the hypothesis that in ICSF, both attached and unattached stones occur as a result of a common pathogenic mechanism. That is, in this type of stone former, CaOx stones—even those not showing morphology that betrays attachment—all originate attached to interstitial plaque on the renal papilla.

Borrelia miyamotoi infections among wild rodents show age and month independence and correlation with Ixodes persulcatus larval attachment in Hokkaido, Japan.  

PubMed

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.

Report of the APSAC task force on attachment therapy, reactive attachment disorder, and attachment problems.  

PubMed

Although the term attachment disorder is ambiguous, attachment therapies are increasingly used with children who are maltreated, particularly those in foster care or adoptive homes. Some children described as having attachment disorders show extreme disturbances. The needs of these children and their caretakers are real. How to meet their needs is less clear. A number of attachment-based treatment and parenting approaches purport to help children described as attachment disordered. Attachment therapy is a young and diverse field, and the benefits and risks of many treatments remain scientifically undetermined. Controversies have arisen about potentially harmful attachment therapy techniques used by a subset of attachment therapists. In this report, the Task Force reviews the controversy and makes recommendations for assessment, treatment, and practices. The report reflects American Professional Society on the Abuse of Children's (APSAC) position and also was endorsed by the American Psychological Association's Division 37 and the Division 37 Section on Child Maltreatment.

An attachment perspective on psychopathology  

PubMed Central

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.

Inhibition of fibroblast attachment.  

PubMed

Reattachment is at present an ephemeral goal. There is, therefore, much interest in clarifying the events which determine patterns of cellular repopulation of denuded cementum during periodontal healing, and thus determine the outcome of reattachment surgery. It has previously been reported that human saliva inhibits the initial attachment or subsequent locomotion of human gingival fibroblast-like cells on plastic substrata in vitro, and that this property is a function of a high molecular weight sulphated glycoprotein in saliva. Recent work reported here shows that saliva in vitro also inhibits attachment to human cementum in serum-free medium. This effect can be reversed by superficial citric acid (pH 1.0) demineralisation of saliva-treated cementum. However, demineralisation itself does not augment cell attachment to either saliva-coated or normal cementum compared with controls. It is postulated that adsorption of saliva on cementum in vivo may lead to periodontal wound healing by repair (long junctional epithelium) rather than by regeneration of ligament and cementum; a novel explanation for the previously reported efficacy of citric acid in wound healing might be related to its ability to remove adsorbed saliva from the root surface and thus permit early root colonisation by connective tissue cells.

Depression and attachment problems.  

PubMed Central

This study investigated the characteristics related to attachment of 42 depressed psychiatric patients and 42 non-depressed psychiatric controls. The depressed subjects demonstrated an anxious pattern of attachment, characterized by either intense care-seeking in relation to their attachment figure or angry withdrawal from their attachment figure when their desire for security was frustrated. The results are discussed in terms of Bowlby's attachment construct.

Attachment Without Fear  

PubMed Central

John Bowlby hypothesized an attachment system that interacts with caregiving, exploration, and fear systems in the brain, with a particular emphasis on fear. Neurobiological research confirms many of his hypotheses and also raises some new questions. A psychological model based on this neurobiological research is presented here. The model extends conventional attachment theory by describing additional attachment processes independent of fear. In this model, the attachment elements of trust, openness, and dependence interact with the caregiving elements of caring, empathy, and responsibility.

Temperament and attachment disorders.  

PubMed

Reviewed in this article is research on children with reactive attachment disorder (RAD) who exhibit specific patterns of socially aberrant behavior resulting from being maltreated or having limited opportunities to form selective attachments. There are no data explaining why 2 different patterns of the disorder, an emotionally withdrawn-inhibited pattern and an indiscriminate-disinhibited pattern, arise from similarly aberrant environments. In this article, we consider whether temperamental differences might contribute to the different manifestations of reactive attachment disorder (RAD) in the context of adverse environments. Although the association between attachment and temperament has been studied extensively and has been the subject of spirited debate within the field of child development, there are no extant data on the influence of temperament on the development of attachment disorders. We consider possible directions for research efforts designed to explore the biological underpinnings of the complex phenomenon of attachment disorders. PMID:15028539

Electron attachment to PSCl3.  

PubMed

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

A comparison of two measures to assess adult attachment.  

PubMed

The purpose of this study was to determine the relationship between two different approaches to the assessment of adult attachment. The approaches were C. Hazan and P. R. Shaver's (1987) categorization of three attachment styles and the dimensional system of the Reciprocal Attachment Questionnaire (RAQ; M. West & A. Sheldon-Keller, 1992). Participants were 196 (72 men and 124 women) respondents to a community survey. Multiple regression results showed that the three attachment groups differed significantly on three dimensions of the RAQ: feared loss of the attachment figure, perceived availability of the attachment figure, and use of the attachment figure. In addition, men and women differed significantly on use of the attachment figure, independent of their attachment style. The results indicate that the two approaches to the assessment of adult attachment are interrelated in meaningful ways. PMID:9729840

Client attachment, attachment to the therapist and client-therapist attachment match: How do they relate to change in psychodynamic psychotherapy?  

PubMed

Abstract Objective: We examined the associations between client attachment, client attachment to the therapist, and symptom change, as well as the effects of client-therapist attachment match on outcome. Clients (n = 67) and their therapists (n = 27) completed the ECR to assess attachment. Method: Clients completed also the Client Attachment to Therapist scale three times (early, middle, and late sessions) and the OQ-45 at intake and four times over the course of a year of psychodynamic psychotherapy. Results: Clients characterized by avoidant attachment and by avoidant attachment to their therapist showed the least improvement. A low-avoidant client-therapist attachment match led to a greater decrease in symptom distress than when a low-avoidant therapist treated a high-avoidant client. Conclusions: These findings suggest the importance of considering client-therapist attachment matching and the need to pay attention to the special challenges involved in treating avoidant clients in order to facilitate progress in psychotherapy.

Attachment style changes following intensive short-term group psychotherapy.  

PubMed

In this study, we examined changes in attachment style as measured by the Relationship Scales Questionnaire before and after six weeks of intensive group psychotherapy. We also investigated whether changes in attachment style were associated with changes in interpersonal functioning. Results indicated that participants showed increases in secure attachment and decreases in fearful attachment and, to a lesser degree, preoccupied attachment styles. Change was not found in the dismissive attachment style. Changes in Secure and/or Fearful (but not Preoccupied) attachment styles were related to changes in interpersonal functioning on seven of the eight subscales of the Inventory of Interpersonal Problems. Overall findings suggest intensive group psychotherapy programs show promise for reducing attachment pathology and improving interpersonal functioning. Assessing differential responsiveness to psychotherapy may help us align our interventions to better address differing attachment styles through modifications in focus and approach. PMID:23252815

Micromechanical die attachment surcharge  

DOEpatents

An attachment structure is disclosed for attaching a die to a supporting substrate without the use of adhesives or solder. The attachment structure, which can be formed by micromachining, functions purely mechanically in utilizing a plurality of shaped pillars (e.g. round, square or polygonal and solid, hollow or slotted) that are formed on one of the die or supporting substrate and which can be urged into contact with various types of mating structures including other pillars, a deformable layer or a plurality of receptacles that are formed on the other of the die or supporting substrate, thereby forming a friction bond that holds the die to the supporting substrate. The attachment structure can further include an alignment structure for precise positioning of the die and supporting substrate to facilitate mounting the die to the supporting substrate. The attachment structure has applications for mounting semiconductor die containing a microelectromechanical (MEM) device, a microsensor or an integrated circuit (IC), and can be used to form a multichip module. The attachment structure is particularly useful for mounting die containing released MEM devices since these devices are fragile and can otherwise be damaged or degraded by adhesive or solder mounting.

Attachment and early maltreatment.  

PubMed

Attachment outcomes of 31 maltreatment cases (extreme neglect or abuse) selected from a total poverty sample of 267 high-risk mothers were compared at 12 and 18 months to a subsample of 33 cases with a history of excellent care. In accordance with the Bowlby-Ainsworth hypothesis, the maltreatment group was characterized by a low proportion of secure attachment (Ainsworth's group B) at 12 months (38% compared to 75% in the excellent care group and 55% in the remaining total sample); however, differences at 18 months were not significant. Specifically, 50% of the cases with a history of neglect were in Ainsworth's group C (anxious/resistant attachment) at 12 months, compared to usual reports of approximately 10% and compared to 21% in the total poverty sample. Patterns of attachment between 12 and 18 months remained stable for the mother-infant pairs in the excellent care group, however, 52% of the mistreated infants changed classifications. For the neglect subgroup there was considerable movement toward Ainsworth's group A (anxious/avoidant attachment) at 18 months and some movement toward group B. An examination of the case histories of mother-infant pairs indicated that changes in attachment between 12 and 18 months were related to changing life events, support from family, and out-of-home care. These findings are highly tentative as were the findings which suggested that secure attachment within the maltreatment group was associated with the presence of a supportive family member, less chaotic life-style, and, in some instances, a more robust infant.

The reversibility of virus attachment to mineral surfaces  

USGS Publications Warehouse

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.

Superego: an attachment perspective.  

PubMed

With the help of attachment theory and research, the paper attempts to broaden and build on classical and current views on the superego. Attachment theory's epigenetic approach and the concept of the subliminal superego are described. The superego, it is argued, is as much concerned with safety as sex. The superego is 'heir', not just to the Oedipus complex or Klein's pre-oedipal constellation, but also to the attachment relationship. Under favourable developmental conditions a 'mature superego' emerges, facilitating, in the presence of an internal secure base, maturational boundary crossings towards adult sexuality. In the light of the above, the paper reviews Lear's updating of Strachey's model of psychic change and explores the concept of transgression in relation to the 'professional superego', its development and maturation. Theoretical arguments are illustrated with clinical examples. PMID:22014367

ENSO Page  

NSDL National Science Digital Library

ENSO PAGE, provided by the National Weather Service in the San Francisco Bay Area, is a collection of links dealing with a variety of ENSO (El Nino/Southern Oscillation) related topics such as impacts, sea surface temperature charts, indices and analyses, and background information. 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).

Internal pipe attachment mechanism  

DOEpatents

An attachment mechanism is described for repairing or extending fluid carrying pipes, casings, conduits, etc. utilizing one-way motion of spring tempered fingers to provide a mechanical connection between the attachment mechanism and the pipe. The spring tempered fingers flex to permit insertion into a pipe to a desired insertion depth. The mechanical connection is accomplished by reversing the insertion motion and the mechanical leverage in the fingers forces them outwardly against the inner wall of the pipe. A seal is generated by crushing a sealing assembly by the action of setting the mechanical connection. 6 figures.

Emergence of tempered preferential attachment from optimization  

PubMed Central

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.

Anxious attachment and relationship processes: an interactionist perspective.  

PubMed

Relationship processes in adult romantic relationships have been vastly studied under the aegis of attachment theory. Attachment theory is interactionist in nature, proposing that individual differences in levels of both attachment avoidance and anxiety predict an individual's thoughts, feelings, and behaviors in contexts that activate attachment concerns. A growing body of research is beginning to systematically test the conditions in which individual differences in attachment orientations both predict and fail to predict relationship processes. In this article, we focus on anxious attachment and review a program of research showing that the potentially destructive relationship processes typically observed in highly anxious individuals do not always appear in neutral or benign contexts, or when security needs are met. We argue that research needs to more thoroughly investigate the conditions that should, or should not, activate attachment concerns and thus result in links between individual differences in attachment orientations and relationship processes.

Attachment in the brain: adult attachment representations predict amygdala and behavioral responses to infant crying.  

PubMed

Current research found that adult attachment representations influence neural, emotional, and behavioral responses to infant crying, thus validating the Berkeley Adult Attachment Interview with functional Magnetic Resonance Imaging. This study examined amygdala activation, feelings of irritation, and the use of excessive force as indicated by grip strength using a handgrip dynamometer during exposure to infant crying and scrambled control sounds in 21 women without children. Individuals with insecure attachment representations showed heightened amygdala activation when exposed to infant crying compared to individuals with secure attachment representations. In addition, insecure individuals experienced more irritation during infant crying and used more excessive force than individuals with a secure representation. Amygdala hyperactivity might be one of the mechanisms underlying the experience of negative emotions during exposure to infant crying in insecure individuals and might explain why insecure parents respond inconsistently to infant signals or reject their infants' attachment behavior.

Attachment, skin deep? Relationships between adult attachment and skin barrier recovery  

PubMed Central

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.

Attachment behavior and mother-child conversations as predictors of attachment representations in middle childhood: a longitudinal study.  

PubMed

This study examines longitudinal links between mother-child conversations and attachment patterns in early childhood and later attachment representations. It also tests the role of conversations as mediators in the association between behavioral security and attachment representations. Mother-child conversations (snack-time) and attachment behaviors (Separation-Reunion procedure) were assessed for 83 5.5-year-olds while attachment representations (attachment narratives) were measured at 8.5 years of age. Results showed correspondence between attachment behaviors and representations for secure-confident, ambivalent-preoccupied, and disorganized/controlling-frightened groups. Affective quality of mother-child conversations predicted both child attachment behaviors and representations. Secure and confident children showed greater integration of affective information, ambivalent and preoccupied children more affect exaggeration, and disorganized/controlling and frightened children more chaotic conversations. Avoidant children tended to show more affect minimization in conversations. Finally, mother-child conversations centered on the sharing of emotions and thoughts mediated the relation between behavioral and representational attachment security, which underscores the importance of mother-child conversations in the development of attachment representations in childhood.

Adult attachment styles and the psychological response to infant bereavement  

PubMed Central

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.

Surface-attachment sequence in Vibrio Cholerae  

NASA Astrophysics Data System (ADS)

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.

In this paper, we briefly review the evidence that variation in EW morphology can influence the ecology of herbivorous insects directly, by affecting their attachment to plant surfaces, and indirectly by affecting attachment by actively foraging predatory insects to plant surfaces. We then present new data examining how EW micromorphology and chemical composition of Brassica oleracea influence attachment by the predatory beetle, Hippodamia convergens (Coccinellidae). Bioassays with genotypes of B. oleracea differing in wax characteristics, and with EW extracts from these plants applied to glass, show that wax crystals disrupt attachment. In addition, bioassays show that attachment by H. convergens differs among EW extracts prepared to have smooth surfaces without crystals. The differences in attachment under these conditions are evidently due to the chemical composition of the waxes. Bioassays with two pure wax constituents show that wax composition can significantly affect attachment by H. convergens. The study opens the way for using a similar approach to understand attachment by insects to waxy plant surfaces. PMID:21680392

Multiplex PageRank  

PubMed Central

Many complex systems can be described as multiplex networks in which the same nodes can interact with one another in different layers, thus forming a set of interacting and co-evolving networks. Examples of such multiplex systems are social networks where people are involved in different types of relationships and interact through various forms of communication media. The ranking of nodes in multiplex networks is one of the most pressing and challenging tasks that research on complex networks is currently facing. When pairs of nodes can be connected through multiple links and in multiple layers, the ranking of nodes should necessarily reflect the importance of nodes in one layer as well as their importance in other interdependent layers. In this paper, we draw on the idea of biased random walks to define the Multiplex PageRank centrality measure in which the effects of the interplay between networks on the centrality of nodes are directly taken into account. In particular, depending on the intensity of the interaction between layers, we define the Additive, Multiplicative, Combined, and Neutral versions of Multiplex PageRank, and show how each version reflects the extent to which the importance of a node in one layer affects the importance the node can gain in another layer. We discuss these measures and apply them to an online multiplex social network. Findings indicate that taking the multiplex nature of the network into account helps uncover the emergence of rankings of nodes that differ from the rankings obtained from one single layer. Results provide support in favor of the salience of multiplex centrality measures, like Multiplex PageRank, for assessing the prominence of nodes embedded in multiple interacting networks, and for shedding a new light on structural properties that would otherwise remain undetected if each of the interacting networks were analyzed in isolation.

Electromagnetic attachment mechanism  

NASA Technical Reports Server (NTRS)

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.

Social Bookmarking Induced Active Page Ranking  

NASA Astrophysics Data System (ADS)

Social bookmarking services have recently made it possible for us to register and share our own bookmarks on the web and are attracting attention. The services let us get structured data: (URL, Username, Timestamp, Tag Set). And these data represent user interest in web pages. The number of bookmarks is a barometer of web page value. Some web pages have many bookmarks, but most of those bookmarks may have been posted far in the past. Therefore, even if a web page has many bookmarks, their value is not guaranteed. If most of the bookmarks are very old, the page may be obsolete. In this paper, by focusing on the timestamp sequence of social bookmarkings on web pages, we model their activation levels representing current values. Further, we improve our previously proposed ranking method for web search by introducing the activation level concept. Finally, through experiments, we show effectiveness of the proposed ranking method.

Attachment and Adolescent Psychosocial Functioning  

PubMed Central

To explore the meaning and function of attachment organization during adolescence, its relation to multiple domains of psychosocial functioning was examined in a sample of 131 moderately at-risk adolescents. Attachment organization was assessed using the Adult Attachment Interview; multiple measures of functioning were obtained from parents, adolescents, and their peers. Seczurity displayed in adolescents' organization of discourse about attachment experiences was related to competence with peers (as reported by peers), lower levels of internalizing behaviors (as reported by adolescents), and lower levels of deviant behavior (as reported by peers and by mothers). Preoccupation with attachment experiences, seen in angry or diffuse and unfocused discussion of attachment experiences, was linked to higher levels of both internalizing and deviant behaviors. These relations generally remained even when other attachment-related constructs that had been previously related to adolescent functioning were covaried in analyses. Results are interpreted as suggesting an important role for attachment organization in a wide array of aspects of adolescent psychosocial development.

Attachment systems for mandibular implant overdentures: a systematic review  

PubMed Central

PURPOSE The aim of this systematic review was to address treatment outcome according to attachment systems for mandibular implant overdentures in terms of implant survival rate, prosthetic maintenance and complications, and patient satisfaction. MATERIALS AND METHODS A systematic literature search was conducted using PubMed and hand searching of relevant journals considering inclusion and exclusion criteria. Clinical trial studies on mandibular implant overdentures until August, 2010 were selected if more than one type of overdenture attachment was reported. Twenty four studies from 1098 studies were finally included and the data on implant survival rate, prosthetic maintenance and complications, patient satisfaction were analyzed relative to attachment systems. RESULTS Four studies presented implant survival rates (95.8 - 97.5% for bar, 96.2 - 100% for ball, 91.7% for magnet) according to attachment system. Ten other studies presented an implant survival rate ranging from 93.3% to 100% without respect to the attachment groups. Common prosthetic maintenance and complications were replacement of an assay for magnet attachments, and activation of a matrix or clip for ball or bar attachments. Prosthetic maintenance and complications most commonly occurred in the magnet groups. Conflicting findings were found on the rate of prosthetic maintenance and complications comparing ball and bar attachments. Most studies showed no significant differences in patient satisfaction depending upon attachment systems. CONCLUSION The implant survival rate of mandibular overdentures seemed to be high regardless attachment systems. The prosthetic maintenance and complications may be influenced by attachment systems. However patient satisfaction may be independent of the attachment system.

Hot melt adhesive attachment pad  

NASA Technical Reports Server (NTRS)

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.

Mental representations of attachment in eating disorders: a pilot study using the Adult Attachment Interview.  

PubMed

Mental representations of attachment in a sample of adults with Eating Disorders (ED) were assessed using the Adult Attachment Interview (AAI). Sixty subjects participated in the study: 30 non-clinical and 30 clinical. The results obtained showed a specific distribution of attachment patterns in the clinical sample: 10% Free/Autonomous (F), 47% Insecure-Dismissing (Ds), 17% Insecure-Entangled/Preoccupied (E) and about 26% disorganized (CC/U). The two samples differed in their attachment pattern distribution and were significantly different on some coding system scales. Further information was obtained by analyzing differences between the three ED subtypes considered (i.e. Anorexia Nervosa, Bulimia Nervosa and Binge Eating Disorder) and by investigating the differential role of the two parental figures in the definition of attachment representations. Results showed potential benefits in using the AAI coding system scales in addition to the main classifications in order to understand better the developmental issues involved in these disorders. Implications for developmental research and clinical nosology are discussed. PMID:19603303

Substratum interfacial energetic effects on the attachment of marine bacteria  

NASA Astrophysics Data System (ADS)

Biofilms represent an ancient, ubiquitous and influential form of life on earth. Biofilm formation is initiated by attachment of bacterial cells from an aqueous suspension onto a suitable attachment substratum. While in certain, well studied cases initial attachment and subsequent biofilm formation is mediated by specific ligand-receptor pairs on the bacteria and attachment substratum, in the open environment, including the ocean, it is assumed to be non-specific and mediated by processes similar to those that drive adsorption of colloids at the water-solid interface. Colloidal principles are studied to determine the molecular and physicochemical interactions involved in the attachment of the model marine bacterium, Cobetia marina to model self-assembled monolayer surfaces. In the simplest application of colloidal principles the wettability of attachment substrata, as measured by the advancing contact angle of water (theta AW) on the surface, is frequently used as an approximation for the surface tension. We demonstrate the applicability of this approach for attachment of C. marina and algal zoospores and extend it to the development of a means to control attachment and release of microorganisms by altering and tuning surface thetaAW. In many cases, however, thetaAW does not capture all the information necessary to model attachment of bacteria to attachment substrata; SAMs with similar thetaAW attach different number of bacteria. More advanced colloidal models of initial bacterial attachment have evolved over the last several decades, with the emergence of the model proposed by van Oss, Chaudhury and Good (VCG) as preeminent. The VCG model enables calculation of interfacial tensions by dividing these into two major interactions thought to be important at biointerfaces: apolar, Lifshitz-van der Waals and polar, Lewis acid-base (including hydrogen bonding) interactions. These interfacial tensions are combined to yield DeltaGadh, the free energy associated with attachment of bacteria to a substratum. We use VCG to model DeltaGadh and interfacial tensions as they relate to model bacterial attachment on SAMs that accumulate cells to different degrees. Even with the more complex interactions measured by VCG, surface energy of the attachment substratum alone was insufficient to predict attachment. VCG was then employed to model attachment of C. marina to a series of SAMs varying systematically in the number of ethylene glycol residues present in the molecule; an identical series has been previously shown to vary dramatically in the number of cells attached as a function of ethylene glycols present. Our results indicate that while VCG adequately models the interfacial tension between water and ethylene glycol SAMs in a manner that predicts bacterial attachment, DeltaGadh as calculated by VCG neither qualitatively nor quantitatively reflects the attachment data. The VCG model, thus, fails to capture specific information regarding the interactions between the attaching bacteria, water, and the SAM. We show that while hydrogen-bond accepting interactions are very well captured by this model, the ability for SAMs and bacteria to donate hydrogen bonds is not adequately described as the VCG model is currently applied. We also describe ways in which VCG fails to capture two specific biological aspects that may be important in bacterial attachment to surfaces:1.) specific interactions between molecules on the surface and bacteria and 2.) bacterial cell surface heterogeneities that may be important in differential attachment to different substrata.

Mechanism of Actin Network Attachment to Moving Membranes  

PubMed Central

Summary Actin filament networks exert protrusive and attachment forces on membranes and thereby drive membrane deformation and movement. Here, we show that N-WASP WH2 domains play a previously unanticipated role in vesicle movement by transiently attaching actin filament barbed ends to the membrane. To dissect the attachment mechanism, we reconstituted the propulsive motility of lipid-coated glass beads using purified soluble proteins. N-WASP WH2 mutants assembled actin comet tails and initiated movement, but the comet tails catastrophically detached from the membrane. When presented on the surface of a lipid-coated bead, WH2 domains were sufficient to maintain comet tail attachment. In v-Src-transformed fibroblasts, N-WASP WH2 mutants were severely defective in the formation of circular podosome arrays. In addition to creating an attachment force, interactions between WH2 domains and barbed ends may locally amplify signals for dendritic actin nucleation.

The Development and Neurobiology of Infant Attachment and Fear  

PubMed Central

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.

These behaviors are the result of the attachment system, a mammalian trait that exists in order to maximize the odds of survival of an infant born without the necessary maturation for immediate independence. Attachment concepts, such as attachment style, coherence, and reflective functioning,

NEUROENDOCRINE PERSPECTIVES ON SOCIAL ATTACHMENT AND LOVE  

Microsoft Academic Search

The purpose of this paper is to review existing behavioral and neuroendocrine perspectives on social attachment and love. Both love and social attachments function to facilitate reproduction, provide a sense of safety, and reduce anxiety or stress. Because social attachment is an essential component of love, understanding attachment formation is an important step toward identifying the neurobiological substrates of love.

Periodontal disease is manifested clinically by a degradation of the ligament that attaches the tooth to the bone. The most widely used diagnostic tool for assessment of periodontal diseases, measurement of periodontal attachment loss with a manual probe, may overestimate attachment loss by as much as 2 mm in untreated sites, while underestimating attachment loss by an even greater margin

An accelerated clinical chairside technique for casting overdenture attachment copings.  

PubMed

An accelerated technique for casting a direct-pattern post and core restoration for use in fixed prosthodontics has been previously described. Similar techniques for use in removable prosthodontics show potential for clinical use, specifically for the fabrication of radicular stud overdenture attachments and their corresponding copings. The procedure uses a chairside technique and readily available components to fabricate a direct, acrylic resin pattern combining the elements of a cast coping with a fixed radicular attachment. This pattern can subsequently be invested, cast, finished and polished, luted, and attached to the removable prosthesis in a single clinical appointment. PMID:22024184

Attachment of hyaluronan to metallic surfaces.  

PubMed

Metal implants are in general not compatible with the tissues of the human body, and in particular, blood exhibits a severe hemostatic response. Herein we present results of a technique to mask the surface of metals with a natural biopolymer, hyaluronan (HA). HA has minimal adverse interactions with blood and other tissues, but attachment of bioactive peptides can promote specific biological interactions. In this study, stainless steel was cleaned and then surface-modified by covalent attachment of an epoxy silane. The epoxy was subsequently converted to an aldehyde functional group and reacted with hyaluronan through an adipic dihydrazide linkage, thus covalently immobilizing the HA onto the steel surface. Fluorescent labeling of the HA showed that the surface had a fairly uniform covering of HA. When human platelet rich plasma was placed on the HA-coated surface, there was no observable adhesion of platelets. HA derivatized with a peptide containing the RGD peptide sequence was also bound to the stainless steel. The RGD-containing peptide was bioactive as exemplified by the attachment and spreading of platelets on this surface. Furthermore, when the RGD peptide was replaced with the nonsense RDG sequence, minimal adhesion of platelets was observed. This type of controlled biological activity on a metal surface has potential for modulating cell growth and cellular interactions with metallic implants, such as vascular stents, orthopedic implants, heart valve cages, and more.

Attachment in an interpersonal context.  

PubMed

Attachment theory is essentially a child-centred theory which is not readily adaptable to the relating of adults. Dependence is proposed as the adult equivalent of attachment. Both attachment and dependence have both a closeness-seeking component and an upwardly directed component. From this observation emerges a theory of relating constructed around a horizontal axis concerning closeness seeking versus distance seeking and a vertical axis concerning upwardly directed behaviour versus downwardly directed behaviour. By the insertion of four intermediate positions, an octagonal arrangement of relating objectives is created which resembles the interpersonal circle. The theory differs from orthodox interpersonal theory in the clear distinction which is drawn between positive relating and negative relating. Three classes of negative relating are described. As in attachment theory, continuities are established between the relating of animals and the relating of humans. It is tentatively shown how the 10 DSM-IV personality disorders might be accommodated within the structure of the octagon. Psychotherapy based upon interpersonal theory is described. Two instruments for measuring negative relating are described: the Person's Relating to Others Questionnaire, which is a general measure of relating, and the Couple's Relating to Each Other Questionnaire, which measures specifically interrelating within couples. The usefulness of these in measuring change in psychotherapy is illustrated. PMID:9376332

Attachment Theory and Parental Alienation

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.

Temperamental precursors of infant attachment with mothers and fathers.  

PubMed

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.

Patterns of stability in adult attachment: an empirical test of two models of continuity and change.  

PubMed

One of the core assumptions of attachment theory is that attachment representations are stable over time. Unfortunately, the data on attachment stability have been ambiguous, and as a result, alternative theoretical perspectives have evolved to explain them. The objective of the present research was to evaluate alternative models of stability by studying adults in 2 intensive longitudinal investigations. Specifically, we assessed attachment representations in 1 sample (N = 203) daily over a 30-day period and in the other sample (N = 388) weekly over a year. Analyses show that the patterns of stability that exist in adult attachment are most consistent with a prototype model--a model assuming that there is a stable factor underlying temporary variations in attachment. Moreover, although the Big Five personality traits exhibited a pattern of stability that was similar to that of attachment, they did not account for the stability observed in attachment.

Attachment styles as predictors of empathy in nursing students.  

PubMed

Previous studies have traced a relationship between the attachment styles of nurses working as in healthcare teams and their empathy which is an essential characteristic required of people concerned with managing relationships, supporting social events, and improving the of nurse-patient relationships. Since determining the effective variables in the quality of nurse-patient relationships in clinical settings is of paramount importance, current investigation is an effort to examine the relationship between attachment styles and empathy in nursing students. 260 university students (male = 130 and female = 130) were chosen as the sample of the study based upon specific inclusion criteria. All participants completed the Attachment Style Questionnaire (ASQ) and the Interpersonal Reactivity Index (IRI). Data was collected and analyzed using Pearson correlation coefficient and regression analysis with SPSS (v.18). The results showed that secure and insecure attachment styles have significant positive and negative correlation with empathy respectively. Based on the results of regression analysis, it was shown that secure attachment style is predicting 53% of the variance empathy variable, whereas insecure attachment styles are explaining up to 76% of the variance empathy variable collectively. The increase of attention to instructions that focus on empathetic relationships with patients and that are based upon the secure attachment style can result in positive changes in the area of nurse-patient relations and in increasing attention to medical ethics. Findings are consistent with prediction derived from attachment theory and add to our understanding of relationship between attachment styles with empathy in nursing students. The meaning and limitations of this study and suggestions for further research are also discussed. PMID:23908761

ADHD symptoms and attachment representations: considering the role of conduct problems, cognitive deficits and narrative responses in non-attachment-related story stems.  

PubMed

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

Attachment of hyaluronic acid to polypropylene, polystyrene, and polytetrafluoroethylene.  

PubMed

Surfaces of polypropylene (PP), polystyrene (PS) and polytetrafluoroethylene (PTFE) were activated with radio frequency plasmas Ar and NH3 to aminate the polymer surface and were subsequently reacted with hyaluronic acid (HA) in one of the three different attachment schemes. Results show that ammonia plasma treated polymers were more reactive toward HA attachment. The three chemistry schemes consisted of two distinct approaches: (1) direct attachment of the HA to the aminated surface, and (2) extending the reactive group away from the surface with succinic anhydride and then reacting the newly formed carboxylic acid group with an adipic dihydrazide modified HA (HA-ADH). The latter scheme proved to be more effective, suggesting that steric effects were involved with the reactivity of the HA with surface groups. These HA-coated polymers are a candidate for cell attachment and growth. PMID:10619676

Romantic Attachment and Subtypes/Dimensions of Jealousy  

PubMed Central

The present study explored the possible relationship between romantic attachment and jealousy in 100 healthy subjects. The romantic attachment and jealousy were evaluated by means of, respectively, the “Experiences in Close Relationships” questionnaire (ECR), and the “Questionario della Gelosia” (QUEGE). The ECR anxiety scale was related to all QUEGE dimensions, while the ECR avoidance scale to three. Individuals with the preoccupied attachment style showed higher scores than secure subjects on the obsessionality, interpersonal sensitivity and fear of loss dimensions. Fearful-avoidant individuals had higher score than secure subjects on the fear of loss dimension only, while dismissing individuals had lower scores on the self-esteem dimension. These findings suggest that romantic attachment and jealousy are intertwined.

Our chapter describes techniques which can be used to extract the mentioned information as well as tools usable in the analysis of this information. Information about communities could be used in several ways thanks to our approach. Finally, we present experiments which prove the feasibility of our approach. These experiments also show a possible way as to how to measure the similarity of Web pages and Web sites using microgenres. We define the microgenre as a building block of Web pages which is based on the social interaction.

Interpersonal Attachment and Patterns of Ideological Belief  

Microsoft Academic Search

We examine whether two general dimensions of sociopolitical belief—right-wing authori- tarianism (RWA) and social dominance orientation (SDO)—are rooted in insecure psycho- logical attachment. Based on an undergraduate sample (N = 255), we model the relations among attachment styles, general worldviews, RWA, and SDO. A structural equation model indicated that anxious attachment led to RWA but not SDO and that this

PLACE ATTACHMENT: CONCEPTUAL AND EMPIRICAL QUESTIONS  

Microsoft Academic Search

One of the limitations in the study of attachment to place has been its restriction to the spatial range of neighbourhood. Apart from some studies analysing attachment to house, there is a gap regarding other spatial environments. In this sense, we do not know to what extent people can be attached to other spatial categories, i.e., to bigger or smaller

Environmental and genetic influences on early attachment  

Microsoft Academic Search

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,

DNA attachment to support structures  

DOEpatents

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).

Comparison of problematic internet and alcohol use and attachment styles among industrial workers in Korea.  

PubMed

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.

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

PubMed

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.

Methane production by attached film  

DOEpatents

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.

Attachment styles in children affected by migraine without aura  

PubMed Central

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.

Attachment relationship experiences and childhood psychopathology.  

PubMed

Human infants form attachments to their caregivers gradually over the course of the first year of life. Qualitatively different types of attachments, which can be identified by the end of the first year, are broadly predictive of subsequent adaptive outcomes for young children. "Disorganized" patterns of attachment have the strongest links to concurrent and subsequent psychopathology, and considerable research has demonstrated both within-the-child and environmental correlates of disorganized attachment. Clinical disorders of attachment have been demonstrated to arise under conditions of social deprivation, such as institutionalization and maltreatment. An emotionally withdrawn/inhibited pattern and an indiscriminate/disinhibited pattern both have been described. Although these clinical types arise under similar conditions of environmental adversity, they tend to have different courses over time. We describe recent findings and highlight areas of emerging consensus and areas of continuing controversy regarding both disorganized patterns of attachment and clinical disorders of attachment in young children.

Attachment Insecurity and Infidelity in Marriage: Do Studies of Dating Relationships Really Inform Us about Marriage?  

PubMed Central

Attachment theory provides a useful framework for predicting marital infidelity. However, most research has examined the association between attachment and infidelity in unmarried individuals, and we are aware of no research that has examined the role of partner attachment in predicting infidelity. In contrast to research showing that attachment anxiety is unrelated to infidelity among dating couples, 2 longitudinal studies of 207 newlywed marriages demonstrated that own and partner attachment anxiety interacted to predict marital infidelity, such that spouses were more likely to perpetrate infidelity when either they or their partner was high (vs. low) in attachment anxiety. Further, and also in contrast to research on dating couples, own attachment avoidance was unrelated to infidelity whereas partner attachment avoidance was negatively associated with infidelity indicating that spouses were less likely to perpetrate infidelity when their partner was high (vs. low) in attachment avoidance. These effects emerged controlling for marital satisfaction, sexual frequency, and personality, did not differ across husbands and wives, and did not differ across the two studies, with the exception that the negative association between partner attachment avoidance and own infidelity only emerged in one of the two studies. These findings offer a more complete understanding of the implications of attachment insecurity for marital infidelity and suggest that studies of unmarried individuals may not provide complete insights into the implications of various psychological traits and processes for marriage.

Electron attachment to interstellar grains  

NASA Astrophysics Data System (ADS)

We have computed the cross-section for electron collisions with spherical grains at low energies, using both classical and quantum (wave) mechanics. The calculations were found to agree for grain radii as small as 3 × 10-6 cm and collision energies E/k= 10 K. On the other hand, the results of the classical calculations for smaller grains exceed those of wave mechanics by typically a factor of 2, owing to interference effects, which are not present in the classical limit. We suggest that the greatest uncertainty in electron attachment rates is in the value of the sticking coefficient, which may be expected to vary considerably with the composition of the grain and its mantle.

Performance of CdZnTe pixellated radiation detectors assembled by a new attachment method  

NASA Astrophysics Data System (ADS)

This paper presented a new carrier board attachment method for pixellated CdZnTe (CZT) radiation detectors by using a special type of anisotropic conductive film (ACF) based on micro-wires. This ACF has very small pitch, high vertical electrical conductivity, and strong mechanical strength. It was found to be suitable for pixellated CZT detector assembly by optimizing detector fabrication processes and attachment conditions. ACF attached detector modules showed excellent spectra responses. Long-term stability and reliability tests on these detectors showed promising results. This ACF attachment technology had been successfully used for pixellated CZT detectors with various physical dimensions and anode pixel patterns.

Completely extruded talus without soft tissue attachments.  

PubMed

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

Theoretical speculations and empirical data on the relation between attachment and moral reasoning are presented. An autonomous attachment representation was hypothesized to be an important personality dimension facilitating higher levels of moral (Type B) reasoning in adolescence. A sample of 47 U.S. college students (mean age 19.5 years) completed the Adult Attachment Interview (Main & Goldwyn, 1985-1993) and the Sociomoral Reflection Measure-Short Form (Gibbs, Basinger, & Fuller, 1992). Although the overall score for sociomoral reflection was not associated with attachment representation, moral Type B reasoning was more prevalent in respondents with an autonomous attachment representation; thus, autonomous attachment may be at the core of mature moral reasoning.

The mediating role of facebook fan pages.  

PubMed

Using the dual mediation hypothesis, this study investigates the role of interestingness (the power of attracting or holding one's attention) attitude towards the news, in the formation of Facebook Fan Page users' electronic word-of-mouth intentions. A total of 599 Facebook fan page users in Taiwan were recruited and structural equation modeling (SEM) was used to test the research hypotheses. The results show that both perceived news entertainment and informativeness positively influence interestingness attitude towards the news. Interestingness attitude towards the news subsequently influences hedonism and utilitarianism attitudes towards the Fan Page, which then influence eWOM intentions. Interestingness attitude towards the news plays a more important role than hedonism and utilitarianism attitudes in generating electronic word-of-mouth intentions. Based on the findings, the implications and future research suggestions are provided. PMID:24875695

Sine-Bar Attachment For Machine Tools  

NASA Technical Reports Server (NTRS)

Sine-bar attachment for collets, spindles, and chucks helps machinists set up quickly for precise angular cuts that require greater precision than provided by graduations of machine tools. Machinist uses attachment to index head, carriage of milling machine or lathe relative to table or turning axis of tool. Attachment accurate to 1 minute or arc depending on length of sine bar and precision of gauge blocks in setup. Attachment installs quickly and easily on almost any type of lathe or mill. Requires no special clamps or fixtures, and eliminates many trial-and-error measurements. More stable than improvised setups and not jarred out of position readily.

Tracing detached and attached care practices in nursing education.  

PubMed

The implementation of skills labs in Danish nursing education can, in itself, be viewed as a complexity. The students are expected to eventually carry out their work in a situated hospital practice, but they learn their professional skills in a different space altogether, detached and removed from the hospitals and practising on plastic dummies. Despite the apparent artificiality of the skills lab, this article will show that it is possible to analyse some of the fundamental aspects of care in nursing by ethnographically following this phenomenon of simulation-based training. These particular aspects of care are not explicated in the curriculum or textbooks; however, they surfaced once this crooked approach to studying care in a simulated practice was applied. The article start from the assertion that detached engagements are not recognized within the field of nursing education as an equal component to attachments. Yet empirical cases from the skills lab and hospitals illustrate how students sometimes felt emotionally attached to plastic dummies and how experienced nurses sometimes practised a degree of detachment in relation to human patients. Detached engagements will therefore be presented as part of care practices of nurses - rendering the ability to detach in engagement with patients a professional skill that students also need to learn. In the analysis to follow, attached and detached engagements are located on an equal plane by integrating both into the same conceptual framework, rather than imposing a priori notions about their dialectic relation. The analysis shows that it is the particular intertwinement of attachment and detachment that gives care its fundamental meaning. In conclusion, the need for a conceptual shift from a strong emphasis on attached engagement to a more balanced analytical approach to care work, as involving both attached and detached engagement within Danish nursing education, is advocated.

Attachment and the emotional unit.  

PubMed

Until recently, the mother-child relationship was assumed to be the primary relationship affecting the outcome of an individual. This resulted in the mother-child dyad being seen and studied as separate from the family system in which it is embedded. This article asserts that, in order to understand this dyad adequately, one must understand "how" the family functions as an emotional unit that is guided by processes found in evolution and in relationships between living things. It goes beyond describing the family as a system of influence and seeks to account for the universal processes that occur in natural systems. It posits that the triangle is the basic building block of the emotional unit, and proposes a new theoretical dimension for understanding how attachment extends beyond dyads (such as parent-child) to include the emotional unit as a whole. Through triangles, the parent-child relationship is continually influenced by relationship forces operating within the system as a whole. PMID:8319797

Dissociative electron attachment to triflates  

NASA Astrophysics Data System (ADS)

It is known that understanding of chemical transformations induced by low energy electrons reacting with photoresist components is crucial for effective design of chemically amplified resists in modern lithography. Therefore in present work gas phase studies on dissociative electron attachment to simple alkyl (CF3SO3CH3) and aryl (C6H5SO3CF3 and CF3SO3C6H4CH3) triflates were carried out. The fragmentation pathways under electron impact below 10 eV were identified by means of crossed electron-molecular beam mass spectrometry. Several reaction channels were observed upon an electron capture by the studied compounds, involving single or multiple bond cleavages or intramolecular rearrangement. Three main dissociation channels were observed that are C-O, S-O or C-S bond breakage in the triflate moiety leading to the formation of triflate (OTf), triflyl (Tf) or sulfonate (RSO3) anions, respectively. The results of this work can be helpful at later stage in the improvement of the image quality in post optical lithography processes.

Dissociative electron attachment to triflates  

NASA Astrophysics Data System (ADS)

Gas phase studies of dissociative electron attachment to simple alkyl (CF3SO3CH3) and aryl (C6H5SO3CF3 and CF3SO3C6H4CH3) triflates, model molecules of nonionic photoacid generators for modern lithographic applications, were performed. The fragmentation pathways under electron impact below 10 eV were identified by means of crossed electron-molecular beam mass spectrometry. Major dissociation channels involved C-O, S-O, or C-S bond scissions in the triflate moiety leading to the formation of triflate (OTf-), triflyl (Tf-), or sulfonate (RSO3-) anions, respectively. A resonance leading to C-O bond breakage and OTf- formation in alkyl triflates occurred at electron energies about 0.5 eV lower than the corresponding resonance in aryl triflates. A resonance leading to S-O bond breakage and Tf- formation in aryl triflates occurred surprisingly at the same electron energies as C-O bond breakage. In case of alkyl triflates S-O bond breakage required 1.4 eV higher electron energies to occur and proceeded with substantially lower yields than in aryl triflates. C-S bond scission occurred for all presently studied triflates at energies close to 3 eV.

Perceptual metrics and visualization tools for evaluation of page uniformity  

NASA Astrophysics Data System (ADS)

Uniformity is one of the issues of most critical concern for laser electrophotographic (EP) printers. Typically, full coverage constant-tint test pages are printed to assess uniformity. Exemplary nonuniformity defects include mottle, grain, pinholes, and "finger prints". It is a real challenge to make an overall Print Quality (PQ) assessment due to the large coverage of a letter-size, constant-tint printed test page and the variety of possible nonuniformity defects. In this paper, we propose a novel method that uses a block-based technique to analyze the page both visually and metrically. We use a grid of 150 pixels × 150 pixels ( ¼ inch × ¼ inch at 600-dpi resolution) square blocks throughout the scanned page. For each block, we examine two aspects: behavior of its pixels within the block (metrics of graininess) and behavior of the blocks within the printed page (metrics of nonuniformity). Both ?E (CIE 1976) and the L* lightness channel are employed. For an input scanned page, we create eight visual outputs, each displaying a different aspect of nonuniformity. To apply machine learning, we train scanned pages of different 100% solid colors separately with the support vector machine (SVM) algorithm. We use two metrics as features for the SVM: average dispersion of page lightness and standard deviation in dispersion of page lightness. Our results show that we can predict, with 83% to 90% accuracy, the assignment by a print quality expert of one of two grades of uniformity in the print.

Identity and intimacy during adolescence: connections among identity styles, romantic attachment and identity commitment.  

PubMed

Integration of adult attachment and psychosocial development theories suggests that adolescence is a time when capacities for romantic intimacy and identity formation are co-evolving. The current study addressed direct, indirect and moderated associations among identity and romantic attachment constructs with a diverse sample of 2178 middle adolescents. Identity styles were found to have unique and direct associations with identity commitment. Attachment anxiety showed only indirect associations and attachment avoidance had both direct and indirect associations with identity commitment. Tests of moderation revealed that gender, race and relationship status had no influence on the direct associations of identity styles or romantic attachment with identity commitment. Few differences in association strength among identity styles and romantic attachment emerged for gender or race. However, the differences found for relationship status suggested that relationship experiences adolescents bring to their exploration of identity and intimacy matter for how these two areas of development articulate.

The covalent attachment of polyamines to proteins in plant mitochondria.  

PubMed

Plant mitochondria from both potato and mung bean incorporated radioactivity into acid insoluble material when incubated with labelled polyamines (spermine, spermidine and putrescine). Extensive washing of mitochondrial precipitates with trichloroacetic acid and the excess of cold polyamine failed to remove bound radioactivity. Addition of nonradioactive polyamine stopped further incorporation of radioactivity but did not release radioactivity already bound. The radioactivity is incorporated into the membrane fraction. The labelling process has all the features of an enzymatic reaction: it is long lasting with distinctive kinetics peculiar to each polyamine, it is temperature dependent and is affected by N-ethylmaleimide. The latter inhibits the incorporation of putrescine but stimulates the incorporation of spermine and spermidine. Treatment of prelabelled mitochondria with pepsin releases bound radioactivity thus indicating protein to be the ligand for the attachment of polyamines. HPLC of mitochondrial hydrolysates revealed that the radioactivity bound to mitochondria is polyamines; traces of acetyl polyamines were also found in some samples. On autoradiograms of SDS/PAGE gels several radioactive bands of proteins were detected. Protein sequencing of labelled spots from a 2D gel gave a sequence which was 60% identical to catalase. We suggest that the attachment of polyamines to mitochondrial proteins occurs cotranslationally possibly via transglutaminases. PMID:10091605

Attachment Studies with Borderline Patients: A Review  

PubMed Central

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.

Attachment and Children's Biased Attentional Processing: Evidence for the Exclusion of Attachment-Related Information  

PubMed Central

Research in both infants and adults demonstrated that attachment expectations are associated with the attentional processing of attachment-related information. However, this research suffered from methodological issues and has not been validated across ages. Employing a more ecologically valid paradigm to measure attentional processes by virtue of eye tracking, the current study tested the defensive exclusion hypothesis in late childhood. According to this hypothesis, insecurely attached children are assumed to defensively exclude attachment-related information. We hypothesized that securely attached children process attachment- related neutral and emotional information in a more open manner compared to insecurely attached children. Sixty-two children (59.7% girls, 8–12 years) completed two different tasks, while eye movements were recorded: task one presented an array of neutral faces including mother and unfamiliar women and task two presented the same with happy and angry faces. Results indicated that more securely attached children looked longer at mother’s face regardless of the emotional expression. Also, they tend to have more maintained attention to mother’s neutral face. Furthermore, more attachment avoidance was related to a reduced total viewing time of mother’s neutral, happy, and angry face. Attachment anxiety was not consistently related to the processing of mother’s face. Findings support the theoretical assumption that securely attached children have an open manner of processing all attachment-related information.

ATTACHMENT, BORDERLINE PERSONALITY, AND ROMANTIC RELATIONSHIP DYSFUNCTION  

PubMed Central

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.

Perceived parental attachment and achievement motivation.  

PubMed

A significant amount of research in attachment theory has been devoted to factors affecting academic achievement, but less attention has been given to the role of attachment in the relation between academic achievement and achievement motivation. The current preliminary study examined the role of perceived parental attachment in achievement motivation. Self-report data obtained from the Parental Attachment Questionnaire, Achievement Goals Questionnaire, and the Performance Failure Appraisal Inventory were collected from 50 university students with a mean age of 18.8 yr. Correlation and regression analyses indicated that parental facilitation of independence correlated significantly and negatively with fear of failure. Results yielded partial support for the hypothesis that performance-oriented goals are related to a fear of failure, whereas mastery-oriented goals are not. The results also suggest that high parental attachment in the case of high-frequency religious practitioners is related to an increased chance of acquiring a more avoidance-oriented achievement motivation.

Attachment of Agrobacterium to plant surfaces  

PubMed Central

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.

Attachment, borderline personality, and romantic relationship dysfunction.  

PubMed

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

The Antimicrobial Activity of Porphyrin Attached Polymers  

NASA Astrophysics Data System (ADS)

We are interested in testing the antimicrobial activity of a porphyrin that is attached to a polymer. The porphyrin (5-(4-carboxyphenyl)-10,15,20-tris-(4-pryridyl)) was synthesized from methyl 4-formyl benzoate, 4-pyridinecarboxaldehyde, and pyrrole and attached to a copolymer of polystyrene/poly(vinyl benzyl chloride), which was synthesized by free radical polymerization. The antimicrobial activity of the polymer-attached porphyrin was then determined for gram-negative E. Coli grown to 0.80 OD. In this procedure, glass slides were coated with polymer-attached porphyrin via dip-coating, and the E. Coli bacteria were plated in Luria Broth media. The plates were subsequently exposed to light overnight before they were incubated as porphyrins act as photo-sensitizers when irradiated with light. The polymer-attached porphyrin did exhibit antimicrobial activity and parameters that affect its efficiency will be discussed.

Continuous monitoring of bacterial attachment  

NASA Technical Reports Server (NTRS)

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.

SiC Die Attach for High-Temperature Applications  

NASA Astrophysics Data System (ADS)

Eutectic solders AuIn19 and AuGe12 and nanosilver paste were investigated for SiC die attach in high-temperature (300°C) applications. The soldering or sintering conditions were optimized through die shear tests performed at room temperature. In particular, application of static pressure (3.5 MPa) during sintering resulted in greatly improved mechanical behavior of the nanosilver-based joint. Microstructural study of the eutectic solders showed formation of Au-rich grains in AuGe die attach and significant diffusion of Au and In through the Ni layer in AuIn19 die attach, which could lead to formation of intermetallic compounds. Die shear tests versus temperature showed that the behaviors of the studied die attaches are different; nevertheless they present suitable shear strengths required for high-temperature applications. The mechanical behavior of joints under various levels of thermal and mechanical stress was also studied. Creep experiments were carried out on the eutectic solders to describe the thermomechanical behavior of the complete module; only one creep mechanism was observed in the working range.

Environmental and genetic influences on early attachment  

PubMed Central

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, albeit inconclusive, evidence of the effect of infant temperament. In this paper, after reviewing briefly the well-demonstrated familial and wider environmental influences, the evidence is reviewed for genetic and gene-environment interaction effects on developing early attachment relationships. Studies investigating the interaction of genes of monoamine neurotransmission with parenting environment in the course of early relationship development suggest that children's differential susceptibility to the rearing environment depends partly on genetic differences. In addition to the overview of environmental and genetic contributions to infant attachment, and especially to disorganised attachment relevant to mental health issues, the few existing studies of gene-attachment interaction effects on development of childhood behavioural problems are also reviewed. A short account of the most important methodological problems to be overcome in molecular genetic studies of psychological and psychiatric phenotypes is also given. Finally, animal research focusing on brain-structural aspects related to early care and the new, conceptually important direction of studying environmental programming of early development through epigenetic modification of gene functioning is examined in brief.

Nuclear reactor fuel rod attachment system  

DOEpatents

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.

Homocysteine enhances cardiac neural crest cell attachment in vitro by increasing intracellular calcium levels.  

PubMed

Elevated homocysteine (Hcys) increases the risk of neurocristopathies. Previous studies show Hcys inhibits neural crest (NC) cell migration in vivo. However, the mechanisms responsible for this effect are unknown. Here, we evaluated the effect of Hcys on NC cell attachment in vitro and determined if any of the effects were due to altered Ca2+ signaling. We found Hcys enhanced NC cell attachment in a dose and substrate-dependent manner. Ionomycin mimicked the effect of Hcys while BAPTA-AM and 2-APB blocked the effect of Hcys on NC attachment. In contrast, inhibitors of plasma membrane Ca2+ channels had no effect on NC attachment. Hcys also increased the emission of the intracellular Ca2+-sensitive probe, Fluo-4. These results show Hcys alters NC attachment by triggering an increase in intracellular Ca2+ possibly by generating inositol triphosphate. Hence, the teratogenic effect ascribed to Hcys may be due to perturbation of intracellular Ca2+ signaling. PMID:18651663

Attachment of Vibrio alginolyticus to glass surfaces is dependent on swimming speed.  

PubMed

The attachment of Vibrio alginolyticus to glass surfaces was investigated with special reference to the swimming speed due to the polar flagellum. This bacterium has two types of flagella, i.e., one polar flagellum and numerous lateral flagella. The mutant YM4, which possesses only the polar flagellum, showed much faster attachment than the mutant YM18, which does not possess flagella, indicating that the polar flagellum plays an important role. The attachment of YM4 was dependent on Na+ concentration and was specifically inhibited by amiloride, an inhibitor of polar flagellum rotation. These results are quite similar to those for swimming speed obtained under the same conditions. Observations with other mutants showed that chemotaxis is not critical and that the flagellum does not act as an appendage for attachment. From these results, it is concluded that the attachment of V. alginolyticus to glass surfaces is dependent on swimming speed. PMID:9473049

Fibronectin coating of oxygenator membranes enhances endothelial cell attachment  

PubMed Central

Background Extracorporeal membrane oxygenation (ECMO) can replace the lungs’ gas exchange capacity in refractory lung failure. However, its limited hemocompatibility, the activation of the coagulation and complement system as well as plasma leakage and protein deposition hamper mid- to long-term use and have constrained the development of an implantable lung assist device. In a tissue engineering approach, lining the blood contact surfaces of the ECMO device with endothelial cells might overcome these limitations. As a first step towards this aim, we hypothesized that coating the oxygenator’s gas exchange membrane with proteins might positively influence the attachment and proliferation of arterial endothelial cells. Methods Sheets of polypropylene (PP), polyoxymethylpentene (TPX) and polydimethylsiloxane (PDMS), typical material used for oxygenator gas exchange membranes, were coated with collagen, fibrinogen, gelatin or fibronectin. Tissue culture treated well plates served as controls. Endothelial cell attachment and proliferation were analyzed for a period of 4 days by microscopic examination and computer assisted cell counting. Results Endothelial cell seeding efficiency is within range of tissue culture treated controls for fibronectin treated surfaces only. Uncoated membranes as well as all other coatings lead to lower cell attachment. A confluent endothelial cell layer develops on fibronectin coated PDMS and the control surface only. Conclusions Fibronectin increases endothelial cells’ seeding efficiency on different oxygenator membrane material. PDMS coated with fibronectin shows sustained cell attachment for a period of four days in static culture conditions.

Effects of different biotic substrata on mussel attachment.  

PubMed

Surface colonization by invertebrates can be stimulated or inhibited by cues produced by biofilms, conspecifics or other macroorganisms. To study the effects of living substrata on the attachment of the brown mussel, Perna perna, two different approaches were employed: (1) mussels were distributed in sets of Petri dishes consisting of one sterile set (controls), three sets in which marine biofilms were allowed to develop in aquaria for 1, 7 or 15 days and another set that had been immersed in a natural marine environment for 1-day. There was no significant effect of biofilms on attachment, suggesting that neither age nor the source of the biofilm influenced attachment. (2) Mussels were suspended over PVC panels (controls) and over panels on which Balanus trigonus (Crustacea), Schizoporella errata (Bryozoa), Symplegma rubra or Didemnum speciosum (Ascidiacea) were present. Attachment was significantly higher on the controls and on B. trigonus than on colonial taxa such as S. rubra, S. errata and D. speciosum, probably due to antifouling defenses of these species. The results show that the composition of the biological substratum is an important factor affecting mussel behavior. PMID:19048423

Magnetically Attached Multifunction Maintenance Rover  

NASA Technical Reports Server (NTRS)

A versatile mobile telerobot, denoted the magnetically attached multifunction maintenance rover (MAGMER), has been proposed for use in the inspection and maintenance of the surfaces of ships, tanks containing petrochemicals, and other large ferromagnetic structures. As its name suggests, this robot would utilize magnetic attraction to adhere to a structure. As it moved along the surface of the structure, the MAGMER would perform tasks that could include close-up visual inspection by use of video cameras, various sensors, and/or removal of paint by water-jet blasting, laser heating, or induction heating. The water-jet nozzles would be mounted coaxially within compressed-air-powered venturi nozzles that would collect the paint debris dislodged by the jets. The MAGMER would be deployed, powered, and controlled from a truck, to which it would be connected by hoses for water, compressed air, and collection of debris and by cables for electric power and communication (see Figure 1). The operation of the MAGMER on a typical large structure would necessitate the use of long cables and hoses, which can be heavy. To reduce the load of the hoses and cables on the MAGMER and thereby ensure its ability to adhere to vertical and overhanging surfaces, the hoses and cables would be paid out through telescopic booms that would be parts of a MAGMER support system. The MAGMER would move by use of four motorized, steerable wheels, each of which would be mounted in an assembly that would include permanent magnets and four pole pieces (see Figure 2). The wheels would protrude from between the pole pieces by only about 3 mm, so that the gap between the pole pieces and the ferromagnetic surface would be just large enough to permit motion along the surface but not so large as to reduce the magnetic attraction excessively. In addition to the wheel assemblies, the MAGMER would include magnetic adherence enhancement fixtures, which would comprise arrays of permanent magnets and pole pieces that could be adjusted to maximize or minimize the overall attractive magnetic force. Even with a paint thickness of 2 mm, a preliminary design provides a safety factor of 5 in the magnetic force in the upside- down, water-jets-operating condition, in which the total load (including the weight of the MAGMER and cables and the water-jet force) would be about 260 lb (the weight of 118 kg). Optionally, the MAGMER could carry magnetic shielding and/or could be equipped with a demagnetizing module to remove residual magnetism from the structure. The MAGMER would carry four charge-coupled-device cameras for visual inspection, monitoring of operation, navigation, and avoidance of collisions with obstacles. The control system of the MAGMER would include navigation and collision-avoidance subsystems that would utilize surface features as landmarks, in addition to direct images of obstacles.

[Affective facial behavior of patients with anxiety disorders during the adult attachment interview: a pilot study].  

PubMed

In this study we examined for the first time the difference between patients with an anxiety disorder and healthy controls in their attachment representation and facial affective behavior during the activation of the attachment system. 13 female patients und 14 healthy women were administered with the Adult Attachment Interview (AAI). Facial affective behavior during 6 selected questions of the AAI was coded using the Emotional-Facial-Action-Coding-System (EMFACS). As expected patients with an anxiety disorder, especially panic disorders, were classified significantly more often as insecure-preoccupied with a high proportion of unresolved loss. Against our assumption anxiety patients, independent of their attachment category, did not differ in their facial affective behavior from the control group. A group comparison taking into account diagnosis and attachment status showed that duchenne smile (happiness) was significantly predominant in control subjects classified as secure. Attachment security in healthy subjects, characterized by an overall valuing of positive or negative attachment experiences and coherent discourse in the AAI, was associated with positive facial affectivity. In contrast insecure anxiety patients could be characterized by showing social smile when talking e. g. about former separation experiences from their attachment figures mostly in an incoherent manner. This could be interpreted as a self-regulating defense. Limitations of the study are the small sample size and the heterogeneous clinical group of anxiety disorders. PMID:17377891

Addition of sand to shake-flask cultures seemed to induce exopolymer synthesis by a number of subsurface bacterial isolates, as revealed by optical microscopy. Several additional lines of evidence indicate that exopolymer production by attached cells (in continuous-flow, sand-packed columns) was greater than by their free-living counterparts. The mechanism by which attachment stimulated exopolymer synthesis did not involve changes of the specific growth rate, growth stage, or limiting nutrient.

Thermal electron attachment to SO3  

SciTech Connect

The rate constant for electron attachment to SO3 is 3 + or - 1 x 10(exp-9) cu cm/s at 300 K, measured in helium gas at pressures from 53 to 160 Pa (0.4 to 1.2 torr). The sole product of attachment is SO3(-) under these conditions. The same rate constant and ionic product were obtained at 400 and 505 K. The measurements were carried out using a flowing-afterglow Langmuir-probe apparatus.

Attachment of enteric viruses to bottles.  

PubMed

Storage of water that was deliberately contaminated with enteric viruses in polyethylene terephthalate (PET) bottles led to a rapid decrease of the apparent viral load, thereby hampering the development of samples for a collaborative evaluation of viral detection methods for bottled water. To determine if this decrease was due to spontaneous inactivation or to adhesion, an elution protocol was developed and combined with a rapid and sensitive real-time reverse transcription-PCR-based method to quantify adsorbed norovirus (NV), hepatitis A virus (HAV), and rotavirus (RV) on bottle walls. The NV retention on PET bottle walls after 20 and 62 days reached an average level of 85% and 95% of the recovered inoculum, respectively. HAV and RV also showed adsorption onto PET bottles, reaching 90% and 80%, respectively, after 20 days of storage. NV and RV attachment was demonstrated to be dependent on the presence of autochthonous flora, whereas HAV adsorption was independent of it. Application of the elution and viral detection protocol to 294 commercially available water bottles obtained from 25 different countries did not give any positive result, thereby providing further evidence that the sources used for this product are free from enteric viruses and support for the theory that bottled water is not a vehicle for viral diseases.

Attachment and cancer: a conceptual integration.  

PubMed

Cancer traditionally has been explained by the biomedical model; however, it is limited in comprehensively accounting for all factors in this disease. Recently, it has been suggested that a broader theoretical framework that includes psychosocial components in cancer is needed to complement the traditional approach. The purpose of this article, therefore, is to explore the utility of attachment theory as a biopsychosocial model of both development and health. Attachment, a developmental theory, explains how repeated interactions between caregiver and child in the early years establish lifelong psychosocial, physiological, affective, and cognitive patterns as well as enduring patterns of stress response to threat or illness. Despite attachment theory's biopsychosocial foundation, the application of attachment security as a factor in physical health and psychosomatic medicine is relatively recent. The current work reviews attachment theory and psychosocial literature with regard to cancer and follows with a novel attempt to conceptually integrate both bodies of literature. A concluding integrative model of attachment theory and the type C behavior pattern is provided to illustrate potential links and integrative processes that may lead to disease resilience or vulnerability.

Platinum Attachments on Iron Oxide Nanoparticle Surfaces  

SciTech Connect

Platinum nanoparticles supported on metal oxide surfaces have shown great potential as heterogeneous catalysts to accelerate electrochemical processes, such as the oxygen reduction reaction in fuel cells. Recently, the use of magnetic supports has become a promising research topic for easy separation and recovery of catalysts using magnets, such as Pt nanoparticles supported on iron oxide nanoparticles. The attachment of Pt on iron oxide nanoparticles is limited by the wetting ability of the Pt (metal) on ceramic surfaces. A study of Pt nanoparticle attachment on iron oxide nanoparticle surfaces in an organic solvent is reported, which addresses the factors that promote or inhibit such attachment. It was discovered that the Pt attachment strongly depends on the capping molecules of the iron oxide seeds and the reaction temperature. For example, the attachment of Pt nanoparticles on oleic acid coated iron oxide nanoparticles was very challenging, because of the strong binding between the carboxylic groups and iron oxide surfaces. In contrast, when nanoparticles are coated with oleic acid/tri-n-octylphosphine oxide or oleic acid/oleylamine, a significant increase in Pt attachment was observed. Electronic structure calculations were then applied to estimate the binding energies between the capping molecules and iron ions, and the modeling results strongly support the experimental observations.

Hyperelastic properties of human meniscal attachments.  

PubMed

Meniscal attachments are ligamentous tissues anchoring the menisci to the underlying subchondral bone. Currently little is known about the behavior of meniscal attachments, with only a few studies quantitatively documenting their properties. The objective of this study was to quantify and compare the tensile mechanical properties of human meniscal attachments in the transverse direction, curve fit experimental Cauchy stress-stretch data to evaluate the hyperelastic behavior, and couple these results with previously obtained longitudinal data to generate a more complete constitutive model. Meniscal attachment specimens were tested using a uniaxial tension test with the collagen fibers oriented perpendicular to the loading axis. Tests were run until failure and load-optical displacement data was recorded for each test. The medial posterior attachment was shown to have a significantly greater elastic modulus (6.42±0.78 MPa) and ultimate stress (1.73±0.32 MPa) when compared to the other three attachments. The Mooney-Rivlin material model was selected as the best fit for the transverse data and used in conjunction with the longitudinal data. A novel computational approach to determining the transition point between the toe and linear regions is presented for the hyperelastic stress-stretch curves. Results from piece-wise non-linear longitudinal curve fitting correlate well with previous linear elastic and SEM findings. These data can be used to advance the design of meniscal replacements and improve knee joint finite element models. PMID:20980006

Influence of nanophase titania topography on bacterial attachment and metabolism  

PubMed Central

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.

Play Behavior and Attachment in Toddlers with Autism  

PubMed Central

Play helps to develop social skills. Children with autism show deviances in their play behavior that may be associated with delays in their social development. In this study, we investigated manipulative, functional and symbolic play behavior of toddlers with and without autism (mean age: 26.45, SD 5.63). The results showed that the quality of interaction between the child and the caregiver was related to the development of play behavior. In particular, security of attachment was related to better play behavior. When the developmental level of the child is taken into account, the attachment relationship of the child with the caregiver at this young age is a better predictor of the level of play behavior than the child's disorder.

Brushite cement additives inhibit attachment to cell culture beads.  

PubMed

Brushite-forming calcium phosphate cements are of great interest as bone replacement materials because they are resorbable in physiological conditions. Cell-attached culture beads formed from this material could be of great use for cell therapy. Despite a significant amount of work on optimizing the physicochemical properties of these materials, there are very few studies that have evaluated the capacity of the materials to facilitate cell adhesion. In this study, we have formed resorbable calcium phosphate (brushite) culture beads and for the first time we showed that cell attachment to the surface of the brushite cement (BC) could be inhibited by the presence of an intermediate dicalcium phosphate-citrate complex, formed in the cement as a result of using citric acid, a retardant and viscosity modifier used in many cement formulations. The BC beads formed from the mixture of ?-TCP/orthophosphoric acid using citric acid did not allow cell attachment without further treatment. Ageing of BC beads in serum-free Dulbecco's Modified Eagle's Medium (DMEM) solution at 37°C for 1 week greatly enhanced the cell adhesion capacity of the material. Scanning electron microscopy, X-ray diffraction (XRD), and confocal Raman microspectrometry indicated the increased capacity for cell adhesion was due to the changes in phase composition of BC. XRD patterns collected before and after ageing in aqueous solution and a high initial mass loss, suggest the formation of a dicalcium phosphate-citrate complex within the matrix. Since compacts formed from brushite powder supported cell attachment, it was hypothesized that the dicalcium phosphate-citrate complex prevented attachment to the cement surface. PMID:23242924

Tendons attached to prostheses by tendon-bone block fixation: an experimental study in dogs.  

PubMed

To develop a method of tendon attachment to a metallic endoprosthesis, we evaluated fixation strength, clinical function of the tendon, and morphological changes in an experimental model. The canine supraspinatus tendon was removed from the greater tubercle of the humerus and attached to a titanium prosthesis. In 12 animals, the bone block underlying the tendon insertion was preserved and attached in one limb; the soft part of the tendon was attached directly to the prosthesis in the contralateral limb. Fixation strength was evaluated after 16 weeks of in vivo implantation (12 specimens) and compared with the in vitro fixation strength (12 specimens) and with intact normal controls (six specimens from cadavera). Function of the tendon in vivo was evaluated by force-plate analysis (at 3-week intervals). All specimens were evaluated histologically. Sixteen weeks after surgery, the tendon-bone block attachment was significantly stronger (mean, 16%) than the direct tendon attachment and not significantly different from the normal control, and the direct tendon attachment was significantly weaker (mean, 68%) than the normal control. There was significantly more weight-bearing on the limbs with a tendon-bone block attachment than on the limbs with a direct tendon attachment at both 3 and 6 weeks postoperatively. Both front legs showed increased weight-bearing with time, but the differences were not statistically significant. Anchorage by tissue ingrowth to the titanium prosthesis was found consistently--there was bone ingrowth in the tendon-bone block attachments and fibrous tissue ingrowth in the direct tendon attachments. When a bone block was preserved, the strength and stiffness were comparable with those of a normal tendon insertion.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7983557

Attachment site selection of ticks on roe deer, Capreolus capreolus.  

PubMed

The spatio-temporal attachment site patterns of ticks feeding on their hosts can be of significance if co-feeding transmission (i.e. from tick to tick without a systemic infection of the host) of pathogens affects the persistence of a given disease. Using tick infestation data on roe deer, we analysed preferred attachment sites and niche width of Ixodes ticks (larvae, nymphs, males, females) and investigated the degree of inter- and intrastadial aggregation. The different development stages showed rather consistent attachment site patterns and relative narrow feeding site niches. Larvae were mostly found on the head and on the front legs of roe deer, nymphs reached highest densities on the head and highest adult densities were found on the neck of roe deer. The tick stages feeding (larvae, nymphs, females) on roe deer showed high degrees of intrastadial spatial aggregation, whereas males did not. Male ticks showed large feeding site overlap with female ticks. Feeding site overlap between larval-female and larval-nymphal ticks did occur especially during the months May-August on the head and front legs of roe deer and might allow pathogen transmission via co-feeding. Tick density, niche width and niche overlap on roe deer are mainly affected by seasonality, reflecting seasonal activity and abundance patterns of ticks. Since different tick development stages occur spatially and temporally clustered on roe deer, transmission experiments of tick-borne pathogens are urgently needed. PMID:20585837

Putting up emotional (Facebook) walls? Attachment status and emerging adults' experiences of social networking sites.  

PubMed

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.

The effective photoinduction of Haematococcus pluvialis for accumulating astaxanthin with attached cultivation.  

PubMed

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 65.8mgm(-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

Helicobacter pylori attachment to gastric cells induces cytoskeletal rearrangements and tyrosine phosphorylation of host cell proteins.  

PubMed Central

The consequences of Helicobacter pylori attachment to human gastric cells were examined by transmission electron microscopy and immunofluorescence microscopy. H. pylori attachment resulted in (i) effacement of microvilli at the site of attachment, (ii) cytoskeletal rearrangement directly beneath the bacterium, and (iii) cup/pedestal formation at the site of attachment. Double-immunofluorescence studies revealed that the cytoskeletal components actin, alpha-actinin, and talin are involved in the process. Immunoblot analysis showed that binding of H. pylori to AGS cells induced tyrosine phosphorylation of two host cell proteins of 145 and 105 kDa. These results indicate that attachment of H. pylori to gastric epithelial cells resembles that of enteropathogenic Escherichia coli. Coccoid H. pylori, which are thought to be terminally differentiated bacterial forms, are capable of binding and inducing cellular changes of the same sort as spiral H. pylori, including tyrosine phosphorylation of host proteins.

Assessment of attachment of Neisseria gonorrhoeae to HeLa cells by double radiolabeling.  

PubMed Central

Attachment of Neisseria gonorrhoeae to HeLa cells was assessed by a technique using double radioisotopic labeling. Piliated, virulent bacteria from colony type 2 attached to HeLa cells to a greater extent than nonpiliated, avirulent bacteria from colony type 4. Maximal attachment rates for bacteria from both colony types occurred during the early incubation periods at 37 degrees C, and the HeLa cells appeared saturated at 4 h. Attachment was maximum at pH 6.5 and dependent upon the multiplicity of infection. Treatment of the HeLa cells with trypsin diminished the degree of attachment, but this effect substantially disappeared by 24 h after trypsin treatment. Scanning electron microscopy revealed bacteria of colony types 2 and 4 adhered to the HeLa cell surface. Thin-section transmission electron microscopy showed that bacteria were associated with the surface of the HeLa cell but not ingested. Images

Initial attachment of human oral keratinocytes cultured on zirconia or titanium.  

PubMed

Initial attachment of human oral keratinocytes (HOKs) cultured on mirror-surfaced commercially pure titanium (Ti) or yttria-stabilized tetragonal zirconia polycrystals (TZP) was investigated. Numbers of viable attached HOKs, their mRNAs and proteins expression of laminin ?2 and integrin ?4 were evaluated using the WST-1 assay, quantitative real-time PCR and enzyme-linked immunosorbent assay, respectively. Localization of laminin ?2 and integrin ?4 was observed using immunofluorescent staining. Cell spreading was evaluated by measuring the perimeter of actin on fluorescent stained images, and cell morphology was examined using scanning electron microscopy. At 1 h TZP elicited less of initial attachment than Ti in terms of mRNAs expression and proteins expression of laminin ?2 and integrin ?4 (p<0.05). However, at 48 h TZP was showed similar initial attachment in comparison to Ti. Therefore, it was suggested that TZP has a potential to form epithelial attachment like Ti. PMID:22673460

Prediction of Substrate Removal Rates of Attached Microorganisms and of Relative Contributions of Attached and Suspended Communities at Field Sites  

PubMed Central

A mathematical model composed of a direct proportionality relationship between bulk water velocities and field-determined second-order microbial transformation rate coefficients, and the relative rate coefficient of a benchmark chemical, was developed for estimating the substrate removal rates of rapidly degraded chemicals by attached organisms in shallow (<1 m deep) aquatic ecosystems. Data from 31 field experiments involving the addition of 2,4-dichlorophenoxyacetic acid methyl ester (2,4-DME) in nine field areas were used to determine a field-derived second-order rate coefficient for microbial transformation of the ester. By using 2,4-DME as a benchmark chemical, the model was used to predict microbial transformation rates of the butoxyethyl ester of 2,4-dichlorophenoxyacetic acid (2,4-DBE) at five other field sites. The predicted half-lives of 2,4-DBE varied 1,500-fold and were within about a threefold range or less of the measured half-lives. Under conditions of mass transport limitation, the contributions of attached microorganisms relative to total microbial activities at various field sites were related to the ratio of water velocity, U, and depth, D, showing that historical definitions of ecosystems according to flow and depth characteristics are also valid for describing the process-related structure of ecosystems. An equation was developed for predicting the relative contributions of attached and suspended communities with values of U and D for lotic and lentic ecosystems. On the basis of this equation, attached microorganisms were expected to be insignificant in deep lentic ecosystems and suspended microorganisms were expected to be insignificant in shallow lotic systems for the same process carried out by both populations. Neglecting epiphytic microorganisms, both suspended and attached organisms were expected to be significant in wetlands.

Increased CDK1 activity determines the timing of kinetochore-microtubule attachments in meiosis I  

PubMed Central

Chromosome segregation during cell division depends on stable attachment of kinetochores to spindle microtubules. Mitotic spindle formation and kinetochore–microtubule (K-MT) capture typically occur within minutes of nuclear envelope breakdown. In contrast, during meiosis I in mouse oocytes, formation of the acentrosomal bipolar spindle takes 3–4 h, and stabilization of K-MT attachments is delayed an additional 3–4 h. The mechanism responsible for this delay, which likely prevents stabilization of erroneous attachments during spindle formation, is unknown. Here we show that during meiosis I, attachments are regulated by CDK1 activity, which gradually increases through prometaphase and metaphase I. Partial reduction of CDK1 activity delayed formation of stable attachments, whereas a premature increase in CDK1 activity led to precocious formation of stable attachments and eventually lagging chromosomes at anaphase I. These results indicate that the slow increase in CDK1 activity in meiosis I acts as a timing mechanism to allow stable K-MT attachments only after bipolar spindle formation, thus preventing attachment errors.

Using Graphs to Show Connections  

NSDL National Science Digital Library

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.

Adolescents' paternal attachment and Internet use.  

PubMed

As children approach middle childhood and adolescence, the influence of fathers on children's behavior and development becomes more equivalent to that of mothers. The quality of father-child attachment operates as a stronger predictor of adolescents' cognitive and emotional development. During adolescence, symbolic communication by means of the Internet becomes increasingly more important than physical approximate-seeking behavior in infancy and childhood. Adolescents might regard the Internet as their new attachment figure or may seek new attachment figures through the Internet. This study was designed to address the impacts of father-adolescent attachment on adolescents' Internet use. Seven hundred twelve adolescent participants completed questionnaires to assess the associations among their paternal attachment, intensity of Internet use, and Internet services preference. The result revealed that alienation positively predicted pathological Internet use (PIU) directly and also indirectly mediated by leisure services preference. Trust predicted PIU negatively. These results help to provide parents and educators with guidance in adolescents' more appropriate Internet use. PMID:17927530

Does the attachment system towards owners change in aged dogs?  

PubMed

Changes during senescence can significantly affect both the emotional and relational needs of old individuals and the characteristics of the attachment system. In order to determine whether the emotional response of dogs is affected by old age, we compared the behavioural parameters of adult (AD <7 years of age, n=25) and aged (AG ?7 years of age, n=25) dogs in a distressing situation, which gives rise to attachment behaviour patterns (Strange Situation Test, SST). The physiological response of dogs was assessed by measurement of salivary cortisol variations in samples collected both at the dogs' homes and at the study location, before and after the SST. Both groups of dogs expressed clear-cut patterns of attachment to their owners. During the initial part of the procedure, AG dogs sought more physical contact, but behaved more passively and showed less interest in an unknown person during separation from their owners. Compared with AD dogs, AG ones showed a significant increase in salivary cortisol concentrations after the SST. The combination of physiological and behavioural data of the present study supports the hypothesis that, later in life, dogs cope less efficiently with emotional distress caused by mild social challenge.

Design and Analysis of UHTC Leading Edge Attachment  

NASA Technical Reports Server (NTRS)

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.

Less is more: removing membrane attachments stiffens the RBC cytoskeleton  

NASA Astrophysics Data System (ADS)

The polymerized network of the cytoskeleton of the red-blood cell (RBC) contains different protein components that maintain its overall integrity and attachment to the lipid bilayer. One of these key components is the band 3 ankyrin complex that attaches the spectrin filaments to the fluid bilayer. Defects in this particular component result in the shape transformation called spherocytosis, through the shedding of membrane nano-vesicles. We show here that this transition and membrane shedding can be explained through the increased stiffness of the network when the band 3 ankyrin complexes are removed. ATP-induced transient dissociations lead to network softening, which offsets the stiffening to some extent, and causes increased fragility of these mutant cells, as is observed.

Preferential attachment in the interaction between dynamically generated interdependent networks  

NASA Astrophysics Data System (ADS)

We generalize the scale-free network model of Barabási and Albert (Science, 286 (1999) 509) by proposing a class of stochastic models for scale-free interdependent networks in which interdependent nodes are not randomly connected but rather are connected via preferential attachment (PA). Each network grows through the continuous addition of new nodes, and new nodes in each network attach preferentially and simultaneously to a) well-connected nodes within the same network and b) well-connected nodes in other networks. We present analytic solutions for the power-law exponents as functions of the number of links both between networks and within networks. We show that a cross-clustering coefficient vs. size of network N follows a power law. We illustrate the models using selected examples from the Internet and finance.

Following electron attachment to CS ()  

NASA Astrophysics Data System (ADS)

Parameter-free scattering calculations are carried out for the CS () molecular target interacting with slow electrons (<10 eV) using a quantum dynamical approach in the molecular reference frame and varying the internuclear distance over a sizeable range of values. The calculations find a resonant state of in the low-energy region and the resonance is seen to stabilize as a bound CS- molecule when the bond is stretched beyond the CS equilibrium value, in agreement with existing experiments and calculations. An analysis of the excess, metastable electron is able to show that the initially occupied d -orbital of the molecular resonance evolves into a more localized p*-orbital on the sulphur fragment. The results from the calculations are related to the existing experimental data for the title system and to the information we have on the target molecule electron affinity.

Beyond the dyad: do family interactions influence children's attachment representations in middle childhood?  

PubMed

This study examines the influence of mother-child and family interactions on the development of child attachment representations in middle childhood for a sample of 49 families. Mother-child interactions were observed during a snacktime in a lab setting (Moss, Rousseau, Parent, St-Laurent, & Saintonge, 1998) when children were 5-6 years old. Three years later, children's attachment representations were assessed using a doll play narrative procedure (Solomon, George, & DeJong, 1995) in the lab setting. Within 6 months of the second lab visit, family interactions were filmed during mealtime and coded using the Mealtime Interaction Coding System (MICS; Dickstein, Hayden, Schiller, Seifer, & San Antonio, 1994). Results showed clear differences between attachment groups on quality of mother-child and family interaction with the secure/confident group showing highest and the disorganized/frightened group showing lowest quality interactions. Family interactions predicted children's attachment representations, after controlling variance explained by prior mother-child interactions. PMID:19016050

Attachment of Mycoplasma pneumoniae to respiratory epithelium.  

PubMed

The attachment of radioisotope-labeled Mycoplasma pneumoniae to hamster tracheal rings in organ culture was examined by radioautography and liquid scintillation counting. Radioautographs of individual rings exposed for 8 h to (3H) thymidine-labeled virulent M. pneumoniae revealed a dense extracellular collection of emulsion grains along the luminal surface of epithelial cells. Similar exposure of rings to isotope-labeled avirulent M. pneumoniae resulted in no accumulation of emulsion grains. The numbers of attached virulent mycoplasmas, as measured by liquid scintillation counting of infected rings, were found to increase in a nearly linear fashion over an 8-h incubation period. Viability of the mycoplasmas and metabolic integrity of the tracheal rings were important for optimal attachment. Pretreatment of rings with neuraminidase or sodium periodate significantly impaired orgainism adherence. These data suggest a specificity of interation between virulent M. pneumoniae and tracheal epithelial cells that can be further examined through the use of isotopically labeled mycoplasmas.

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.

Attaching of strain gages to substrates  

NASA Technical Reports Server (NTRS)

A method and apparatus for attaching strain gages to substrates is described. A strain gage having a backing plate is attached to a substrate by using a foil of brazing material between the backing plate and substrate. A pair of electrodes that are connected to a current source, are applied to opposite sides of the backing plate, so that heating of the structure occurs primarily along the relatively highly conductive foil of brazing material. Field installations are facilitated by utilizing a backing plate with wings extending at an upward incline from either side of the backing plate, by attaching the electrodes to the wings to perform the brazing operation, and by breaking off the wings after the brazing is completed.

Expandable pallet for space station interface attachments  

NASA Technical Reports Server (NTRS)

Described is a foldable expandable pallet for Space Station interface attachments with a basic square configuration. Each pallet consists of a series of struts joined together by node point fittings to make a rigid structure. The struts have hinge fittings which are spring loaded to permit collapse of the module for stowage transport to a Space Station in the payload bay of the Space Shuttle, and development on orbit. Dimensions of the pallet are selected to provide convenient, closely spaced attachment points between the node points of the relatively widely spaced trusses of a Space Station platform. A pallet is attached to a strut at four points: one close fitting hole, two oversize holes, and a slot to allow for thermal expansion/contraction and for manufacturing tolerances. Applications of the pallet include its use in rotary or angular joints; servicing of splints; with gridded plates; as instrument mounting bases; and as a roadbed for a Mobile Service Center (MSC).

Explaining the relationship between insecure attachment and partner abuse: the role of personality characteristics.  

PubMed

Studies have found that male batterers are more often insecurely attached as compared with nonbatterers. However, it is still not clear how insecure attachment is related to domestic violence. Many studies compared batterers and nonbatterers regarding pathological personality characteristics that are related to attachment (e.g., dependency, jealousy) and generally found that batterers report more personality characteristics. However, these studies did not investigate which role these characteristics played in the relationship between insecure attachment and battering. The first aim of this study is to test which personality characteristics are good candidates to explain the relationship between insecure attachment and domestic violence. The second aim is to test whether personality characteristics are predictive of battering over and above attachment. Seventy-two mainly court-mandated family-only males who were in group treatment for battering are allocated to a securely and an insecurely attached group and compared with 62 nonbatterers. Using questionnaires, self-esteem, dependency, general distrust, distrust in partner, jealousy, lack of empathy, separation anxiety, desire for control, and impulsivity were assessed. This was the first study that examined distrust, separation anxiety, and desire for control in relation to battering. The results show that the relationship between insecure attachment and domestic violence can be explained by separation anxiety and partner distrust. Moreover, only partner distrust increased the risk for battering over and above insecure attachment. The findings suggest the presence of two subtypes among batterers based on attachment style, which has similarities to the family-only and dysphoric-borderline subtypes suggested by Holtzworth-Munroe and Stuart. Implications of the present findings for therapy are discussed. PMID:22550146

In this study, two types of carbon nanotube (CNT) modified surfaces for the attachment of Bacillus anthracis spores were examined. Multi-walled carbon nanotube (MWCNT) forest on silicon wafer and MWCNT sheet on poly(methyl methacrylate) (PMMA) film were used. Both types of MWCNT surfaces significantly increased surface hydrophobicity (P < 0.05) and increased the attachment of spores on their surfaces compared to the uncoated substrates, respectively. However, no inhibitory effect was observed on the germination of attached spores on both types of MWCNT surfaces. MWCNT-coated surfaces showed the potential as adsorbents for removal of Bacillus spores from fluids. PMID:22888754

Here, we show that computing the page number is NP-complete; we describe an exact computation of page number, using constraint programming, and determine the page number of a collection of RNA tertiary structures, for which the topological genus is known. We describe an approximation algorithm from which it follows that ?(S) ? ?(S) ? ?(S) ?log n,where the clique number of S, ?(S), denotes the maximum number of base pairs that pairwise cross each other.

Integrin Expression Regulates Neuroblastoma Attachment and Migration1  

PubMed Central

Abstract Neuroblastoma (NBL) is the most common malignant disease of infancy, and children with bone metastasis have a mortality rate greater than 90%. Two major classes of proteins, integrins and growth factors, regulate the metastatic process. We have previously shown that tumorigenic NBL cells express higher levels of the type I insulin-like growth factor receptor (IGF-IR) and that ?1 integrin expression is inversely proportional to tumorigenic potential in NBL. In the current study, we analyze the effect of ?1 integrin and IGF-IR on NBL cell attachment and migration. Nontumorigenic S-cells express high levels of ?1 integrin, whereas tumorigenic N-cells express little ?1 integrin. Alterations in ?1 integrin are due to regulation at the protein level, as translation is decreased in N-type cells. Moreover, inhibition of protein synthesis shows that ?1 integrin is degraded more slowly in S-type cells (SHEP) than in N-type cells (SH-SY5Y and IMR32). Inhibition of ?5?1 integrin prevents SHEP (but not SH-SY5Y or IMR32) cell attachment to fibronectin and increases SHEP cell migration. Increases in IGF-IR decrease ?1 integrin expression, and enhance SHEP cell migration, potentially through increased expression of ?v?3. These data suggest that specific classes of integrins in concert with IGF-IR regulate NBL attachment and migration.

Lightning attachment patterns and flight conditions for storm hazards, 1980  

NASA Technical Reports Server (NTRS)

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.

Ultralow Energy Electron Attachment at Sub-Millielectron Volt Resolution  

NASA Technical Reports Server (NTRS)

The technique of rare-gas photoionization has been extended by use of direct laser ionization to electron energies epsilon in the range 0-100 meV, with a resolution Delta(epsilon) of 0.4-0.5 meV (FWHM). Tunable UV light at (Lambda)276 nm is produced using a pulsed Nd:YAG laser and nonlinear mixing techniques. The beam is frequency tripled in a pulsed jet of xenon. The VUV radiation, tunable at (Lambda)92 nm, is then used to photoionize Xe at its 2P(sub 1/2) threshold (single-photon ionization). The photoelectrons produced interact with admixed target gas to generate negative ions through the s-wave capture process. Recent results in electron attachment to SF(sub 6) will be reported which show resonance structure at the opening of the ground-state vibrational channels. This structure corresponds to the process of vibrational excitation + attachment, which is superimposed on the underlying s-wave (direct) capture process. It should be a general phenomenon, present in a wide variety of zero-energy electron attaching molecules.

Comparing Two Attachment Classification Methods Applied to Preschool Strange Situations  

PubMed Central

This study compared two methods for classifying preschool-age children's behavior in the Strange Situation procedure, the MacArthur (MAC) and the Preschool Assessment of Attachment (PAA), to determine whether they operationalized converging or diverging approaches to attachment theory. Strange Situations of 306 randomly selected 3-year-old children and their mothers in the NICHD Study of Early Child Care and Youth Development were classified with the MAC and PAA. The methods showed 50% agreement. A block of seven demographic, child and family predictors was unrelated to MAC classifications, but accounted for 19% of the variance in PAA classifications. The MAC and PAA each had associations with some child outcomes in grades 1-5 (ages 6-10) totalling 5% and 12% of the variance respectively, but some of the MAC associations were counter to the hypothesis. The MAC and PAA were sufficiently different to reflect both different classificatory methods and different theoretical understandings of attachment. Results are discussed in terms of limitations of the sample and measures available to compare the two methods, and clinical implications.

Assessing attachment in school-age children.  

PubMed

The School-age Assessment of Attachment (SAA) is a newly developed clinical tool to identify pattern of attachment using the Dynamic-Maturational Model of attachment and adaptation (DMM). Seven picture cards were used to elicit fantasy stories and recalled episodes. The transcribed discourse was analyzed to yield one of 13 DMM attachment classifications, together with possible unresolved traumas and losses, and modifiers (depression and intrusions). In this article, we outline the steps necessary to validate an assessment tool, describe the development of the SAA, and report data from a preliminary clinical study testing the SAA's reliability, validity, and utility. Concurrent construct, familial, and discriminant validity were evaluated in terms of mental health status and exposure to danger on a sample of 5-12-year-old children, drawn from clinical ( n = 51) and normative (n = 40) populations. The SAA (a) differentiated children referred for psychiatric diagnosis from those in the normative population; (b) accounted for 31% of the variance (46% when family variables were added); (c) identified risk children in the normative sample; and (d) suggested risk factors associated with children's psychiatric disorder.

Mechanisms of hepatocyte attachment to keratin biomaterials.  

PubMed

Keratin biomaterials support cellular adhesion, proliferation and migration, which have led to their exploitation in a variety of biomedical applications. The mechanism of cell adhesion to keratin biomaterials, however, is poorly understood. Therefore, the goal of this work was to investigate the mechanisms by which human hair keratin-based biomaterials facilitate cellular adhesion. Hepatocytes were used as a model cell type due to the abundance of published data on cell adhesion mechanisms and their relatively copious attachment to keratin substrates. The roles of ?(1)- and ?(2)-integrins and the hepatic asialoglycoprotein receptor (ASGPR) in hepatocyte adhesion to keratin substrates were studied using attachment assays with and without function blocking antibodies. Blocking of the hepatic integrin subunits did not decrease hepatocyte attachment to keratin. Furthermore, adhesion to keratin did not result in the formation of focal complexes or focal adhesions, nor did it produce an upregulation of phosphorylated-focal adhesion kinase. However, inhibition of hepatic ASGPR decreased the ability of hepatocytes to attach to keratin substrates, which is indicative of the role of this glycoprotein receptor in hepatocyte binding to keratin biomaterials.

Thermal electron attachment to F2  

NASA Astrophysics Data System (ADS)

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.

Sexuality examined through the lens of attachment theory: attachment, caregiving, and sexual satisfaction.  

PubMed

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

Children with disrupted attachment histories: Interventions and psychophysiological indices of effects  

PubMed Central

Diagnosis and treatment of children affected by disruptions of attachment (out of home placement, multiple changes of primary caregiver) is an area of considerable controversy. The possible contribution of psychobiological theories is discussed in three parts. The first part relates the attachment theoretical perspective to major psychobiological theories on the developmental associations of parent-child relationships and emotional response. The second part reviews studies of autonomic reactivity and HPA-axis activity with foster children, showing that foster children show more reactivity within physiological systems facilitating fight or flight behaviours rather than social engagement, especially foster children with atypical attachment behaviour. The third part is focused on treatment of children suffering from the consequences of disrupted attachment, based on a psychotherapy study with psychophysiological outcome measures. Implications are discussed for theory, diagnosis, and intervention.

Casimir experiments showing saturation effects

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 ; 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 ; 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 of the change in oscillation frequency of a R87b 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.

Photoemission electron attachment ion mobility spectrometry (PE-EA-IMS), with a source of photoelectrons induced by vacuum ultraviolet radiation on a metal surface, has been developed to study electron attachment reaction at atmospheric pressure using nitrogen as the buffer gas. Based on the negative ion mobility spectra, the rate constants for electron attachment to tetrachloromethane and chloroform were measured at ambient temperature as a function of the average electron energy in the range from 0.29 to 0.96 eV. The experimental results are in good agreement with the data reported in the literature.

We investigated the intermittent convective plasma transport in a attached and?or detached plasma condition of the linear divertor plasma simulator, NAGDIS-II. Images taken by a fast-imaging camera clearly show that in attached plasmas, blobs are peeled off the bulk plasma, and propagate outward with an azimuthal motion. In detached plasmas, plasma turbulence observed near the plasma recombining region drives strong intermittent radial plasma transport, which could broaden the radial density profile.

HBV infection of cell culture: evidence for multivalent and cooperative attachment  

PubMed Central

Hepadnaviruses do not infect cultured cells, therefore our knowledge of the mechanism of the early stages of virus–cell interaction is rather poor. In this study, we show that dimethylsulfoxide (DMSO)-treated HepG2 hepatoblastoma cells are infected efficiently by serum-derived hepatitis B virus (HBV) as monitored by viral gene expression and replication markers. To measure virus attachment, a variety of HBV surface proteins (HBsAgs) were conjugated to polystyrene beads and their capacity to attach cells was visualized and quantified by light microscopy at a single-cell resolution. Remarkably, DMSO increases the attachment efficiency by >200-fold. We further identify the QLDPAF sequence within preS1 as the receptor-binding viral domain epitope. Interestingly, a similar sequence is shared by several cellular, bacterial and viral proteins involved in cell adhesion, attachment and fusion. We also found that the small HBsAg contains a secondary attachment site that recognizes a distinct receptor on the cell membrane. Furthermore, we provide evidence in support of multivalent HBV attachment with synergistic interplay. Our data depict a mechanistic view of virus attachment and ingestion.

Characterization of somatic embryo attached structures in Feijoa sellowiana Berg. (Myrtaceae).  

PubMed

The presence of an attached organ to somatic embryos of angiosperms connecting the embryo to the supporting tissue has been a subject of controversy. This study shows that 67% of the morphologically normal somatic embryos of Feijoa sellowiana possess this type of organ and that its formation was not affected by culture media composition. Histological and ultrastructural analysis indicated that the attached structures of somatic embryos displayed a great morphological diversity ranging from a few cells to massive and columnar structures. This contrast with the simple suspensors observed in zygotic embryos which were only formed by five cells. As well as the suspensor of zygotic embryos, somatic embryo attached structures undergo a process of degeneration in later stages of embryo development. Other characteristic shared by zygotic suspensors and somatic embryo attached structures was the presence of thick cell walls surrounding the cells. Elongated thin filaments were often associated with the structures attached to somatic embryos, whereas in other cases, tubular cells containing starch grains connected the embryo to the supporting tissue. These characteristics associated with the presence of plasmodesmata in the cells of the attached structures seem to indicate a role on embryo nutrition. However, cell proliferation in the attached structures resulting into new somatic embryos may also suggest a more complex relationship between the embryo and the structures connecting it to the supporting tissue.

Attachment style, anxiety coping, and personality-styles in withdrawn alcohol addicted inpatients  

PubMed Central

Background Insecure early attachment experiences have been reported to play an important role in the manifestation in alcoholism. The purpose of this study was to investigate the relationship of attachment styles with anxiety, anxiety coping and dysfunctional personality styles, as well as with the prevalence of personality disorders, and adverse life-events in adolescence. Methods 59 inpatient alcohol addicted male (n=43) and female (n=16) patients were characterized by an attachment style scale (Relationships-style-questionnaire-RSQ) and completed a questionnaire battery comprising the State-Trait-Anxiety-Inventory (STAI), the Anxiety-Coping-Inventory (ABI), Temperament-and-character-inventory (TCI), Personality-system-interaction-inventory (PSI), and gave information on sociodemography, alcohol history, and adolescent adverse events. A structured interview (SKID-II) was performed to diagnose personality disorders. Results Only 33% of subjects had a secure attachment style. Insecure attachment was associated with significantly higher trait-anxiety, higher cognitive avoidance to control anxiety, and higher values on most personality style dimensions directed to the pathological pole. Conclusions Despite the limitation due to a small sample size, the results of this study show that the consideration of attachment styles is of significance in the diagnosis and therapy of alcohol addiction. Attachment may characterize different styles to control emotional aspects, anxiety cues and interpersonal relationships in individuals suffering from alcohol addiction.

Pictorial representation of attachment: measuring the parent-fetus relationship in expectant mothers and fathers  

PubMed Central

Background Over the past decades, attachment research has predominantly focused on the attachment relationship that infants develop with their parents or that adults had with their own parents. Far less is known about the development of feelings of attachment in parents towards their children. The present study examined a) whether a simple non-verbal (i.e., pictorial) measure of attachment (Pictorial Representation of Attachment Measure: PRAM) is a valid instrument to assess parental representations of the antenatal relationship with the fetus in expectant women and men and b) whether factors such as gender of the parent, parity, and age are systematically related to parental bonding during pregnancy. Methods At 26 weeks gestational age, 352 primi- or multiparous pregnant women and 268 partners from a community based sample filled in the PRAM and the M/PAAS (Maternal/Paternal Antenatal Attachment Scale, Condon, 1985/1993). Results Results show that the PRAM was significantly positively associated to a self-report questionnaire of antenatal attachment in both expectant mothers and fathers. Age and parity were both found significantly related to M/PAAS and PRAM scores. Conclusions The present findings provide support that the PRAM is as a valid, quick, and easy-to-administer instrument of parent-infant bonding. However, further research focusing on its capacity as a screening instrument (to identify parents with serious bonding problems) and its sensitivity to change (necessary for the use in evaluation of intervention studies) is needed, in order to prove its clinical value.

Placement in Foster Care Enhances Quality of Attachment Among Young Institutionalized Children  

PubMed Central

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.

Autonomic reactivity in relation to attachment and early adversity among foster children.  

PubMed

This study examined whether the quality of relationships with foster caregivers was associated with autonomic nervous system reactivity of children during separation and reunion with their foster caregiver. Moreover, effects of early adversity were examined in relation to attachment and autonomic nervous system reactivity. The sample included 60 children between 26 and 88 months of age, who participated with their primary foster caregivers in the Strange Situation. Respiratory sinus arrhythmia and preejection period were measured as indicators of parasympathetic and sympathetic nervous system reactivity, respectively. Attachment quality (ordered/disordered and secure/insecure attachment), was coded on the basis of children's behavior in the Strange Situation using the Cassidy and Marvin coding system. Children with a background of neglect and those with disordered (disorganized-controlling or insecure-other) attachment showed most sympathetic reactivity during the procedure. Moreover, children with disordered attachment showed less vagal regulation (respiratory sinus arrhythmia decreases on separation and increases on reunion) than children with ordered attachment. The findings show that the quality of relationships with current caregivers, and to a lesser extent specific experiences of neglect, may have an impact on children's abilities to regulate emotions in the context of environmental stress and challenges.

Mimas Showing False Colors #1  

NASA Technical Reports Server (NTRS)

False color images of Saturn's moon, Mimas, reveal variation in either the composition or texture across its surface.

During its approach to Mimas on Aug. 2, 2005, the Cassini spacecraft narrow-angle camera obtained multi-spectral views of the moon from a range of 228,000 kilometers (142,500 miles).

The image at the left is a narrow angle clear-filter image, which was separately processed to enhance the contrast in brightness and sharpness of visible features. The image at the right is a color composite of narrow-angle ultraviolet, green, infrared and clear filter images, which have been specially processed to accentuate subtle changes in the spectral properties of Mimas' surface materials. To create this view, three color images (ultraviolet, green and infrared) were combined into a single black and white picture that isolates and maps regional color differences. This 'color map' was then superimposed over the clear-filter image at the left.

The combination of color map and brightness image shows how the color differences across the Mimas surface materials are tied to geological features. Shades of blue and violet in the image at the right are used to identify surface materials that are bluer in color and have a weaker infrared brightness than average Mimas materials, which are represented by green.

Herschel crater, a 140-kilometer-wide (88-mile) impact feature with a prominent central peak, is visible in the upper right of each image. The unusual bluer materials are seen to broadly surround Herschel crater. However, the bluer material is not uniformly distributed in and around the crater. Instead, it appears to be concentrated on the outside of the crater and more to the west than to the north or south. The origin of the color differences is not yet understood. It may represent ejecta material that was excavated from inside Mimas when the Herschel impact occurred. The bluer color of these materials may be caused by subtle differences in the surface composition or the sizes of grains making up the icy soil.

The images were obtained when the Cassini spacecraft was above 25 degrees south, 134 degrees west latitude and longitude. The Sun-Mimas-spacecraft angle was 45 degrees and north is at the top.

The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. The Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, D.C. The Cassini orbiter and its two onboard cameras were designed, developed and assembled at JPL. The imaging operations center is based at the Space Science Institute in Boulder, Colo.

Observing attachment behavior in couples: the Adult Attachment Behavior Q-Set (AABQ).  

PubMed

Knowledge as to how attachment behavior is observable in couple interaction can be very useful to clinicians who use attachment theory or related theories to guide their work with couples. The development of the Adult Attachment Behavior Q-Set (AABQ), a 100-item Q-sort designed to be consistent with Main's Adult Attachment Interview (AAI) coding system, is described. Videotaped discussions were coded for a sample of 28 couples. The majority of the couples were married and had sought therapy for couple problems. Reliability of coding was adequate. Evidence for validity was promising, with a match of 84% between the AAI and AABQ for secure versus insecure, and 70% for the three categories of secure, dismissing, and preoccupied. Even though additional reliability and validity information are needed for the AABQ, it holds promise for providing insights into couple dynamics that could be useful in guiding interventions and in evaluating the outcome of couple therapy.

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

NASA Astrophysics Data System (ADS)

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.

Mechanisms of attachment of Mycoplasma arthritidis to host cells in vitro.  

PubMed

Although other investigators have reported that Mycoplasma arthritidis failed to attach to several types of mammalian cells in vitro, we showed that it attached well to rat synovial fibroblasts, lung cells, and skin cells but not to kidney cells, suggesting that receptor sites are unequally expressed or distributed among different rat tissues. M. arthritidis also attached poorly to canine kidney and to baby hamster kidney cells, although it did attach to human fetal lung and fetal amnion cells. Four M. arthritidis strains, two virulent and two avirulent, all attached equally well to rat lung cells. Attachment was inhibited by trypsinization, suggesting that the major adhesins are protein. Fab' fractions of rabbit antisera against four M. arthritidis strains partially inhibited adherence of both homologous and heterologous strains, although not to the same extent, indicating some degree of antigenic heterogeneity among their adhesins. A filter-cloned variant of M. arthritidis 158p10p9, designated LC1, attached poorly compared with the parent strain. Missing from this variant were two proteins migrating within the 81- to 90-kDa range by polyacrylamide gel electrophoresis; in their place was a 24-kDa antigen that may be a truncated version of one of these proteins. A monoclonal antibody that partially inhibited attachment recognized all these peptides by Western immunoblotting. An additional attachment-inhibiting monoclonal antibody recognized a 71-kDa antigen present in both low-adherence and fully adherent populations. The low-adherence variant LC1 induced slightly but significantly less arthritis in Lewis rats than did a fully adherent clone. PMID:8500906

A radio transmitter attachment technique for soras  

USGS Publications Warehouse

We modified a figure-8 leg-loop harness designed for small passerines to attach successfully 1.8-g radio transmitters over the synsacrum of migrant Soras (Porzana carolina). Because of the short caudal region of Soras, addition of a waist loop was critical to securing the transmitter while leg loops were maintained to center the package. Thin gauge (0.6-mm diameter) elastic thread proved ideal for transmitter attachment and allowed for freedom of movement and girth expansion associated with fattening during a 6-10 week stopover. Of 110 Soras radio tagged during three field seasons, only a single mortality was observed and only a single bird lost its transmitter. Migration from the study area was confirmed for 76 (69%) and suspected for another 25 birds (total 92%).

Method for forming a glove attachment  

NASA Technical Reports Server (NTRS)

An attachment principally for the palm of an astronaut glove to enhance the gripping area of the palm without detracting from the flexibility and utility of the glove is presented. The attachment is a composite construction formed from a layer of silicone rubber having an outer surface with a friction configuration and another layer of silicone rubber in which a Nomex Aramid mesh fabric is embedded prior to curing. The method of construction involves the use of a mold with a friction configuration surface. A first layer of silicone rubber or sealant is disposed in the mold and allowed to set for an hour. A second layer of silicone rubber or sealant is layered over the first layer and leveled. A Nomex Aramid mesh fabric is embedded into the second layer and the composite is permitted to cure. When cured, a configured area of the composite construction is glued or stitched to the palm area of the glove.

Expandable pallet for space station interface attachments  

NASA Technical Reports Server (NTRS)

A foldable expandable pallet having a basic square configuration is disclosed. Each pallet is comprised of a plurality of struts, joined together by node point fittings to make a rigid structure. Some of the struts have hinge fittings and are spring loaded to permit collapse of the module for stowage and transport to a space station. Dimensions of the pallet are selected to provide convenient, closely spaced attachment points between the relatively widely spaced trusses of a space station platform. A pallet is attached to a truss at four points; one close fitting hole; two oversize holes; and a slot; to allow for thermal expansion/contraction and for manufacturing tolerances. Applications of the pallet include its use in rotary or angular joints; servicing of splints; with gridded plates; as an instrument mounting bases; and as a roadbed for a Mobile Service Center (MSC).

Adolescent place attachment, social capital, and perceived safety: a comparison of 13 countries.  

PubMed

In adolescence, children become increasingly independent and autonomous, and spend more time in neighborhood settings away from home. During mid-to-late adolescence, youth often become more critical about the place they live. Their attachment to home and even community may decrease as they explore and develop new attachments to other specific places. The aim of this study is to understand how 15-year-old students from 13 countries perceive their local neighborhood area (place attachment, social capital and safety), and how these different community cognitions are interrelated. We hypothesize that their place attachment predicts safety, and that the relationship is mediated in part by social capital. Result show that, despite cross-cultural differences in neighborhood perceptions, the proposed theoretical model fits robustly across all 13 countries. PMID:19533329

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

PubMed

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

Quality of Attachment Relationships and Peer Relationship Dysfunction Among Late Adolescents With and Without Anxiety Disorders  

PubMed Central

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.

NASA Astrophysics Data System (ADS)

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.

Attachment techniques for high temperature strain  

NASA Astrophysics Data System (ADS)

Attachment methods for making resistive strain measurements to 2500 F were studied. A survey of available strain gages and attachment techniques was made, and the results are compiled for metal and carbon composite test materials. A theoretical analysis of strain transfer into a bonded strain gage was made, and the important physical parameters of the strain transfer medium, the ceramic matrix, were identified. A pull tester to measure pull-out tests on commonly used strain gage cements indicated that all cements tested displayed adequate strength for good strain transfer. Rokide flame sprayed coatings produced significantly stronger bonds than ceramic cements. An in-depth study of the flame spray process produced simplified installation procedures which also resulted in greater reliability and durability. Application procedures incorporating improvements made during this program are appended to the report. Strain gages installed on carbon composites, Rene' 41, 316 stainless steel, and TZM using attachment techniques developed during this program were successfully tested to 2500 F. Photographs of installation techniques, test procedures, and graphs of the test data are included in this report.

Closed coin holder for attachment to pager  

US Patent & Trademark Office Database

A coin holder can hold coins for use in making a telephone call or paying a toll or fare. The coin holder can be attached to any item in any suitable manner, and is quite suitable for attachment to an electronic pager on which individuals are often summoned to make phone calls. The coin holder has an interior and a cover which conceals the coin or coins held in the coin holder. The coin holder can be a piece which is attachable to any item or can be an integral part of the item itself, such as in the instance of an electronic pager, where the housing for the pager can form the interior of the coin holder and a releasably securable cover can be provided to cover that interior and conceal the coin or coins held therein. The housing surface may or may not be altered to accommodate the coin or coins. Where it is not altered, the coin or coins can simply be held against the housing surface. A latching mechanism may include an undercut and a boss member.

Heteroaggregation of Microparticles with Nanoparticles Changes the Chemical Reversibility of the Microparticles' Attachment to Planar Surfaces  

NASA Astrophysics Data System (ADS)

Detachment of homoaggregates and heteroaggregates attached on planar surfaces at primary minima during transients in solution chemistry was theoretically investigated. The homoaggregates were represented as small colloidal clusters with well-defined structures or as clusters generated by randomly packing spheres using Monte Carlo method. The heteroaggregates were modeled as microparticles coated with nanoparticles. Surface element integration technique was adopted to calculate Derjaguin-Landau-Verwey-Overbeek (DLVO) interaction energies for the homoaggregates and heteroaggregates at different ionic strengths. Results show that attached homoaggregates on the planar surface at primary minima are irreversible to reduction of solution ionic strength whether the primary spheres of the homoaggregates are nano- or micro-sized. Heteroaggregation of nanoparticles with a microparticle can cause DLVO interaction energy to decrease monotonically with separation distance at low ionic strengths (e.g., ? 0.01 M), indicating that the heteroaggregates experience repulsive forces at all separation distances. Therefore, attachment of the heteroaggregates at primary minima can be detached upon reduction of ionic strength. Additionally, we showed that the adhesive forces and torques that the aforementioned heteroaggregates experience can be significantly smaller than those experienced by the microspheres without attaching nanoparticles, thus, the heteroaggregates are readily detached via hydrodynamic drag. Results of study provide plausible explanation for the observations in the literature that attached/aggregated particles can be detached/redispersed from primary minima upon reduction of ionic strength, which challenges the common belief that attachment/aggregation of particles in primary minima is chemically irreversible.

Attachment of human primary osteoblast cells to modified polyethylene surfaces.  

PubMed

Ultra-high-molecular-weight polyethylene (UHMWPE) has a long history of use in medical devices, primarily for articulating surfaces due to its inherent low surface energy which limits tissue integration. To widen the applications of UHMWPE, the surface energy can be increased. The increase in surface energy would improve the adsorption of proteins and attachment of cells to allow tissue integration, thereby allowing UHMWPE to potentially be used for a wider range of implants. The attachment and function of human primary osteoblast-like (HOB) cells to surfaces of UHMWPE with various levels of incorporated surface oxygen have been investigated. The surface modification of the UHMWPE was produced by exposure to a UV/ozone treatment. The resulting surface chemistry was studied using X-ray photoelectron spectroscopy (XPS), and the topography and surface structure were probed by atomic force microscopy (AFM) and scanning electron microscopy (SEM), which showed an increase in surface oxygen from 11 to 26 atom % with no significant change to the surface topography. The absolute root mean square roughness of both untreated and UV/ozone-treated surfaces was within 350-450 nm, and the water contact angles decreased with increasing oxygen incorporation, i.e., showing an increase in surface hydrophilicity. Cell attachment and functionality were assessed over a 21 day period for each cell-surface combination studied; these were performed using SEM and the alamarBlue assay to study cell attachment and proliferation and energy-dispersive X-ray (EDX) analysis to confirm extracellular mineral deposits, and total protein assay to examine the intra- and extracellular protein expressed by the cells. HOB cells cultured for 21 days on the modified UHMWPE surfaces with 19 and 26 atom % oxygen incorporated showed significantly higher cell densities compared to cells cultured on tissue culture polystyrene (TCPS) from day 3 onward. This indicated that the cells attached and proliferated more readily on the UV/ozone-treated UHMWPE surfaces than on untreated UHMWPE and TCPS surfaces. Contact guidance of the cells was observed on the UHMWPE surfaces by both SEM and AFM. Scanning electron micrographs showed that the cells were confluent on the modified UHMWPE surfaces by day 10, which led to visible layering of the cells by day 21, an indicator of nodule formation. In vitro mineralization of the extracellular matrix expressed by the HOB cells on the modified UHMWPE surfaces was confirmed by SEM and EDX analysis; spherulite structures were observed near cell protrusions by day 21. EDX analysis confirmed the spherulites to contain calcium and phosphorus, the major constituents in calcium phosphate apatite, the mineral phase of bone. Overall cell attachment, functionality, and mineralization were found to be enhanced on the UV/ozone-modified UHMWPE surfaces, demonstrating the importance of optimizing the surface chemistry for primary HOB cells.

The effect of soil properties on the attachment of MS2 and ØX174 to natural soils  

NASA Astrophysics Data System (ADS)

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.

Attachment of different soil bacteria to arbuscular mycorrhizal fungal extraradical hyphae is determined by hyphal vitality and fungal species.  

PubMed

Attachment of certain bacteria to living arbuscular mycorrhizal fungal extraradical hyphae may be an important prerequisite for interactions between these microorganisms, with implications for nutrient supply and plant health. The attachment of five different strains of gfp-tagged soil bacteria (Paenibacillus brasilensis PB177 (pnf8), Bacillus cereus VA1 (pnf8), Pseudomonas fluorescens SBW25 :: gfp/lux, Arthrobacter chlorophenolicus A6G, and Paenibacillus peoriae BD62 (pnf8)) to vital and nonvital extraradical hyphae of the arbuscular mycorrhizal fungi Glomus sp. MUCL 43205 and Glomus intraradices MUCL 43194 was examined. Arthrobacter chlorophenolicus did not attach to hyphae, whereas the other bacterial strains did to a varying degree. Only P. brasilensis showed greater attachment to vital hyphae than nonvital hyphae of both Glomus species tested. Pseudomonas fluorescens showed a higher attachment to vital compared with nonvital Glomus sp. MUCL 43205 hyphae, whereas this relationship was opposite for attachment to G. intraradices. Both B. cereus and P. peoriae showed higher attachment to nonvital hyphae. This study provides novel evidence that under laboratory conditions soil bacteria differ in their ability to colonize vital and nonvital hyphae and that this can also be influenced by the arbuscular mycorrhizal fungal species involved. The significance of bacterial attachment to mycorrhizal fungal extraradical hyphae is discussed. PMID:16451176
