    Background Totally laparoscopic aortoiliac surgery has been newly developed in China.It is known as the most complex laparoscopic technique to learn because of its high-risk procedures.Analysis of the operation-related complications of this surgery is supposed to be helpful for the early success of this technique.Methods Twelve male patients (56-70 years old) with aortoiliac occlusive disease underwent totally laparoscopic aortoiliac bypass surgery (TLABS) in our institute.Clinical data and operation-related complications were retrospectively analyzed.Results Of the 12 patients,TLABS succeeded in nine and conversion to open surgery occurred in three.One of the converted patients finally died of pulmonary infection.Operation-related complications included bleeding from arterial injury,perforation from colonic injury,graft embolism,residual aortic stenosis,and hydronephrosis.Bleeding in two patients and colonic perforation in one patient resulted in three conversions to open surgery.Intraoperative graft embolectomy and postoperative aortic stenting were performed to resolve the thrombus/embolus-referring complications.Left hydronephrosis,which was thought to result from intraoperative injury and treated with ureteric intubation drainage,recovered 6 months after TLABS.Conclusions Good understanding and avoidance of operation-related complications are important to guarantee the technical success of TLABS.Immediate conversion to open surgery is necessary for saving the patient's life in case of lifethreatening complications.

  12. Dispersion relations in application to chiral two-nucleon dynamics

    Directory of Open Access Journals (Sweden)

    Gasparyan A.M.


    Full Text Available A novel scheme based on the chiral Lagrangian is applied to the nucleon-nucleon interaction close to threshold. Subthreshold partial-wave amplitudes are calculated in chiral perturbation theory and analytically extrapolated above threshold. The constraints imposed by analyticity and unitarity are used to stabilize the extrapolation. A reasonable description of the empirical phase shifts up to laboratory energies Tlab ≃ 300 MeV is obtained in terms of the parameters relevant at next-to-next-to-next-to-leading order. The convergence properties of the method and the comparison with the conventional potential approach are discussed.

  15. Chiral potential renormalized in harmonic-oscillator space

    CERN Document Server

    Yang, C -J


    We renormalize the chiral effective field theory (EFT) potential in harmonic-oscillator (HO) model space. The low energy constants (LECs) are utilized to absorb not just the ultra-violet part of the physics due to the cutoff, but also the infrared part due to the truncation of model space. We use the inverse J-matrix method to reproduce the nucleon-nucleon (NN) scattering phase shifts in the given model space. We demonstrate that by including the NLO correction, the nucleon-nucleon scattering in the continuum could be well reproduced in the truncated HO trap space up to laboratory energy $T_{lab}=100$ MeV with number of HO basis $n_{max}$ as small as 10. A perturbative power counting starts at subleading order is adopted in this work, and how to extract the perturbative contribution is demonstrated. Our work serves as the input to perform ab-initio calculations.

  16. Pion-nucleon scattering in the P11 channel (United States)

    Morioka, S.; Afnan, I. R.


    We present a parametrization of the π-N interaction in the P11 channel in which the amplitude is the sum of a pole part and a non-pole part (t=tpole+tnp) and satisfies two-body unitarity. Here tpole has both the nucleon propagator and the πNN vertex dressed. The final amplitude fits the scattering length and low energy π-N phase shifts (Tlabπ<300 MeV). We study the effect of a resonance in tnp on the phase shifts, πNN coupling constant, and the off-shell behavior of the amplitude.

  18. A Realistic Description of Nucleon-Nucleon and Hyperon-Nucleon Interactions in the SU_6 Quark Model

    CERN Document Server

    Fujiwara, Y; Kohno, M; Nakamoto, C; Suzuki, Y


    We upgrade a SU_6 quark-model description for the nucleon-nucleon and hyperon-nucleon interactions by improving the effective meson-exchange potentials acting between quarks. For the scalar- and vector-meson exchanges, the momentum-dependent higher-order term is incorporated to reduce the attractive effect of the central interaction at higher energies. The single-particle potentials of the nucleon and Lambda, predicted by the G-matrix calculation, now have proper repulsive behavior in the momentum region q_1=5 - 20 fm^-1. A moderate contribution of the spin-orbit interaction from the scalar-meson exchange is also included. As to the vector mesons, a dominant contribution is the quadratic spin-orbit force generated from the rho-meson exchange. The nucleon-nucleon phase shifts at the non-relativistic energies up to T_lab=350 MeV are greatly improved especially for the 3E states. The low-energy observables of the nucleon-nucleon and the hyperon-nucleon interactions are also reexamined. The isospin symmetry break...

    Full Text Available In the last decade, the European Union has approved and launched measures to promote Intercultural Cities, Diversity Management and the Integration of Immigrants in Europe. Despite this European framework, we are now at a crossroads between solidarity and humanity and an important restriction of refugees’ human rights across Europe. In this paper, we try to compare the international approaches to the refugee crisis in different countries in Europe. Data were extracted from Twitter. We obtained thousands of tweets about “refugees”, using this word in six different languages (English, French, German, Italian, Portuguese, and Spanish from end November 2015 to 27 February 2016 as search strings. We performed a discourse analysis, focusing on the comparison between countries. A qualitative analysis with the help of both Atlas ti and T-Lab software was performed. The results showed a diversity of current discourses in Europe about refugees and the refugee crisis (from solidary to xenophobic ones, some of them very characteristic of particular countries or of local events experienced in these countries. These results allow us to reinforce the idea that we are at a key moment for the future development of Europe, especially regarding aspects concerning living together in cities and villages.

  20. HLA class I homologous transcripts in the human embryonal carcinoma cell line Tera-2. (United States)

    Rinke de Wit, T F; Struyk, L; Vloemans, S; Glazebrook, J; Boyle, J M; Stern, P L; van den Elsen, P J


    We have used the human teratocarcinoma-derived embryonal carcinoma cell line Tera-2 cl. 13 to explore the putative expression of novel HLA class I(-like) genes. Serological analyses revealed that Tera-2 cells do not express polymorphic HLA class I (-A, -B, -C) specificities, but do express HLA class I-like antigens. These phenotypic properties parallel those of certain mouse embryonal carcinoma cells. To study the expression of HLA class I(-like) genes in the Tera-2 cells two different approaches were used. Screening of a Tera-2 cDNA library with a full-length HLA class I cDNA probe under conditions that would allow for the identification of relatively distinct HLA class I-like sequences yielded 27 positive clones, all of which were of the regular HLA-A, -B, -C type. Reverse northern hybridizations of the restriction enzyme-digested Tlab region comprising cosmids with Tera-2 cDNA as the probe resulted in the identification of several putative human genes whose equivalents map within the mouse Tla region. However, none of these genes appeared to be structurally related to HLA class I. A putative H3.3 histone gene was identified in the proximal Tla region of the C57BL/10 mouse. It is concluded that no structural homologues of mouse Qa/Tla genes are expressed in the human developmental cell line Tera-2.

  2. Lyman- photodissociation of CH3CFCl2 (HCFC-141b): Quantum yield and translational energy of hydrogen atoms

    Almuth Laeuter; Hans-Robert Volpp; Jai P Mittal; Rajesh K Vatsa


    The collision-free, room temperature gas-phase photodissociation dynamics of CH3CFCl2 (HCFC-141b) was studied using Lyman- laser radiation (121.6 nm) by the laser photolysis/laserinduced fluorescence `pump/probe’ technique. Lyman- radiation was used both to photodissociate the parent molecule and to detect the nascent H atom products via (22P → 12S) laser-induced fluorescence. Absolute H atom quantum yield, H = (0.39 ± 0.09) was determined by calibration method in which CH4 photolysis at 121.6 nm was used as a reference source of well-defined H atom concentrations. The line shapes of the measured H atom Doppler profiles indicate a Gaussian velocity distribution suggesting the presence of indirect H atom formation pathways in the Lyman- photodissociation of CH3CFCl2. The average kinetic energy of H atoms calculated from Doppler profiles was found to be T(lab) = (50 ± 3) kJ/mol. The nearly statistical translational energy together with the observed Maxwell-Boltzmann velocity distribution indicates that for CH3CFCl2 the H atom forming dissociation process comes closer to the statistical limit.

  3. Dyadic Coping in Couple Therapy Process: An Exploratory Study. (United States)

    Margola, Davide; Donato, Silvia; Accordini, Monica; Emery, Robert E; Snyder, Douglas K


    This study aimed at moving beyond previous research on couple therapy efficacy by examining moment-by-moment proximal couple and therapist interactions as well as final treatment outcomes and their reciprocal association. Seven hundred four episodes of dyadic coping within 56 early therapy sessions, taken from 28 married couples in treatment, were intensively analyzed and processed using a mixed-methods software (T-LAB). Results showed that negative dyadic coping was self-perpetuating, and therapists tended to passively observe the negative couple interaction; on the contrary, positive dyadic coping appeared to require a therapist's intervention to be maintained, and successful interventions mainly included information gathering as well as interpreting. Couples who dropped out of treatment were not actively engaged from the outset of therapy, and they used more negative dyadic coping, whereas couples who successfully completed treatment showed more positive dyadic coping very early in therapy. Results highlight the role of therapist action and control as critical to establishing rapport and credibility in couple therapy and suggest that dyadic coping patterns early in therapy may contribute to variable treatment response. © 2017 Family Process Institute.

  4. “Does Community Make Any Sense?” A Semantic Analysis of the Term “Community” Among Albanian Immigrants and Italian Majority Residents

    Directory of Open Access Journals (Sweden)

    Terri Mannarini


    Full Text Available Bridging Community Psychology and the Theory of Social Representations, the study was aimed at exploring how the concept of community and sense of belonging to various communities vary across diverse ethno-cultural groups (namely, immigrant and native-born groups and how the meanings and the experience of community affect or are affected by the relationships that each group establishes with the other group. Participants were 30 native-born Italians and 30 immigrants from Albania living in an area located in the south-east of Italy. They participated in an open-ended semi-structured interview, which was analysed using T-Lab software. Results indicated that the concept of community and sense of belonging to multiple communities do vary across diverse ethno-cultural groups and that each group is cross-cut by multiple axes of differentiation, one of which is linked to the experience of inter-cultural relations. Furthermore, the findings indicated that the functions served by the diverse communities affect the representations shared by the distinct sub-groups and that the simultaneous orientation of individuals toward multiple communities stimulate the development of a compound and even conflicting sense of attachment towards them. Implications for acculturation processes are discussed.

    CERN Document Server

    Bauer, F


    Excitation functions of the spin correlation coefficients A_{NN}(p_{lab},theta_{c.m.}), A_{SS}(p_{lab},theta_{c.m.}), and A_{SL}(p_{lab},theta_{c.m.}) have been measured with the polarized proton beam of the Cooler Synchrotron COSY and an internal polarized atomic beam target. Data were taken continuously during the acceleration for proton momenta p_{lab} ranging from 1000 to 3300 MeV/c (kinetic energies T_{lab} 450 - 2500 MeV) as well as for discrete momenta of 1430 MeV/c and above 2000 MeV/c covering angles theta_{c.m.} between 30 deg and 90 deg. The data are of high internal consistency. Whereas A_{SL}(p_{lab,}theta_{c.m.}) is small and without structures in the whole range, A_{NN} and even more A_{SS} show a pronounced energy dependence. The angular distributions for A_{SS} are at variance with predictions of existing phase shift analyses at energies beyond 800 MeV. The impact of our results on phase shift solutions is discussed. The direct reconstruction of the scattering amplitudes from all available pp...

  6. Consumption in Action. Mapping consumerism in international academic literature

    Directory of Open Access Journals (Sweden)

    Chiara Pattaro


    Full Text Available The consumer-citizen and more generally, the emergence of active forms of citizenship mediated by consumption point to a change in the relations of production, consumption and distribution. These forms of citizenship come to encompass opposite poles of consumption such as hedonism and social responsibility. When consumption choices are associated with the social and environmental issues connected to manufacturing and distribution processes, the space claimed by the active consumer comes to represents a form of social identity recognition. This ‘political’ sphere, made up of individual and/or collective claims mediated by consumer society comes in the wake of a long period of market de-politicization. On the basis of these assumptions, this article surveys and evaluates the topics related to critical consumption that are most discussed in the social sciences. Such forms of socially oriented consumption – enacted in the form of individual or collective consumer choices – represent a new form of political participation and are understood as practices of active-citizenship promotion. The findings of this article are based on data gathered from 478 peer-reviewed articles published between 2004 and 2013. The articles were selected from Scopus on the basis of their broad connection to critical consumerism and forms of socially oriented consumerism. A software-based content analysis run through T-Lab software was used to generate an analytical model of the main research axis of the most recent international literature on these arguments. The heterogeneous body of scholarly literature on socially oriented consumption reflects the rich diversity of perspectives adopted to understand the political and ethical role of consumers in contemporary societies

  7. Environmental health risk communication in the case "Terra dei Fuochi": content analysis of online newspaper articles. (United States)

    Barchitta, M; Fragapane, S; Quattrocchi, A; Consoli, M T; Giuffrida, G; Pennisi, C; Agodi, A


    The aim of the study is to evaluate the way in which information is conveyed by one of the major national newspapers, in its online version,, about health risks associated with the "Terra dei Fuochi". A retrospective systematic search in the online newspaper database was carried out for articles published from 1st January through 13th May 2014. The keyword used was "Terra dei Fuochi". A corpus, containing all articles included, was built in order to perform content analysis and text-mining using the T-LAB software, together with a critical interpretation. The co-occurrence analysis was performed using the keywords: environment, prevention, waste , risk and science. A total of 211 articles were retrieved, but only 188 articles met the inclusion criteria and were included in the analysis. The section of publication with the largest number of articles was represented by Repubblica Napoli edition with 50% of articles, whereas, only 2% of articles were included in the Environment section, and no article has been placed in the Health section. The most occurring lemmas were: waste, Naples, President, environmental - environment and health. Lemmas as disaster, drama, alarm and fear occur with medium frequency. Among the lemmas with less occurrence there were: remediation, cancer, people, information and recycle. However, terms as communication and risk management were absent. This study contributes to our understanding of how environmental health risks associated with the "Terra dei Fuochi" issue are presented by the newspapers to the public, which has implications for how the public may learn about risk management information.
