Authors: Ali H.A.M. , Ibrahim Magdy A. 
Published: June 2016

AbstractThe crystal structure of (4E)-2-amino-3-cyanobenzo[b]oxocin-6-one, denoted as 4(E)-ACBO, was analyzed using X-ray diffraction technique. The dielectric and AC electrical conductivity measurements of the bulk 4(E)-ACBO in the form of pellet were studied in the range of frequency 42 Hz to 5 MHz and the temperature range of 303 K to 373 K. The temperature and frequency dependence of dielectric constant (∊1), dielectric loss (∊2) and AC electrical conductivity (σAC) were investigated. The relaxation time (τ) for electrons to hop over a barrier of height WHwas calculated at different temperatures. The AC activation energy was determined from the temperature dependence of σACat different frequencies.
Deciphering lead and cadmium stripping peaks for porous antimony deposited electrodes
Authors: Taimoor Aqeel Ahmad 
Published: June 2016

AbstractCadmium and lead are generally taken as model heavy metal ions in water to scale the detection limit of various electrode sensors, using electrochemical sensing techniques. These ions interact with the electrochemically deposited antimony electrodes depending on the diffusion limitations. The phenomenon acts differently for thein-situandex-situdeposition as well as for porous and non-porous electrodes. A method has been adopted in this study to discourage the stripping and deposition of the working ions (antimony) to understand the principle of heavy metal ion detection. X-ray photoelectron spectroscopy (XPS) technique was used to establish the interaction between the working and dissolved ions. In addition to the distinct peaks for each analyte, researchers also observed a shoulder peak. A possible reason for the presence of this peak was provided. Different electrochemical tests were performed to ascertain the theory on the basis of the experimental observations.

Abstract Although transparent conductive oxides such as indium tin oxide (ITO) are widely employed as transparent conducting electrodes (TCEs) for applications such as touch screens and displays, new nanostructured TCEs are of interest for future applications, including emerging transparent and flexible electronics. A number of twodimensional networks of nanostructured elements have been reported, including metallic nanowire networks consisting of silver nanowires, metallic carbon nanotubes (m-CNTs), copper nanowires or gold nanowires, and metallic mesh structures. In these single-component systems, it has generally been difficult to achieve sheet resistances that are comparable to ITO at a given broadband optical transparency. A relatively new third category of TCEs consisting of networks of 1D-1D and 1D-2D nanocomposites (such as silver nanowires and CNTs, silver nanowires and polycrystalline graphene, silver nanowires and reduced graphene oxide) have demonstrated TCE performance comparable to, or better than, ITO. In such hybrid networks, copercolation between the two components can lead to relatively low sheet resistances at nanowire densities corresponding to high optical transmittance. This review provides an overview of reported hybrid networks, including a comparison of the performance regimes achievable with those of ITO and single-component nanostructured networks. The performance is compared to that expected from bulk thin films and analyzed in terms of the copercolation model. In addition, performance characteristics relevant for flexible and transparent applications are discussed. The new TCEs are promising, but significant work must be done to ensure earth abundance, stability, and reliability so that they can eventually replace traditional ITO-based transparent conductors.

Considering the Statistical Distribution of Dynamic Fracture Toughness Data and the Actual Loading Rate at Fracture Initiation When Applying ASTM E1921 at Elevated Loading Rates
Authors: Mayer U. 
Published: June 2016

Abstract
ASTM E1921-15a describes the determination of the reference temperature T0,X for the loading rate X for ferritic steels in the transition range, where X is the order of magnitude of the average loading rate of the tests evaluated. Because this rate is defined for the linear-elastic part of a test only, the definition of the loading rate, valid for tests showing not only linear-elastic but also plastic behavior, is important. In a research project investigating the correlation of dynamic crack initiation and crack arrest funded by the German government, tests at −20°C on specimens of 22 NiMoCr 3 7 steel (A 508 Cl.2) were performed with different specimen geometry and loading devices in the range from 105 MPa√m s−1 to 3 × 106 MPa√m s−1. Evaluation according to ASTM E1921 shows differences of up to 30 K in T0,X obtained from linear-elastic test series and T0,X obtained from elastic-plastic test series with comparable dK/dt. New results were obtained in the current follow-up joint IWM-MPA project from test series at a loading rate of 5 × 105 MPa√m s−1. Results from tests with 1T C(T)-specimen at various test temperatures in the transition region are presented, analyzed, and reference temperature T0,5 is evaluated. The statistical distribution of the determined dynamic fracture toughness values KId resp., KJc,d and the determination of the characteristic loading rate in the case of elastic-plastic tests is discussed. This analysis shows the need of modifications of the standard evaluation method in ASTM E1921, if used for tests at elevated loading rate. The assumed statistical distribution has to be adapted and the actual loading rate at fracture initiation has to be taken into account. Suggestions for the considerations and requirements for the evaluation of data determined at elevated loading rates are presented.
Statistical Modeling of High Cycle Fatigue with Censored Data
Authors: Harlow D. G. , Cao H. , Schmidt P. 
Published: June 2016

Abstract
Characterization and prognosis of materials subjected to very high cycle fatigue is an important aspect of life cycle design and management for structural components. This procedure is even more critical for components in devices that are implanted into humans because of the lack of opportunities for periodic inspection and the severe consequences of failure. The primary structural component of a commercially available heart valve consists of highly-resilient, cold-worked Elgiloy wire, a cobalt-chromium based alloy. In order to be assured of sufficiently high reliability for the component, an extensive high cycle fatigue testing program was conducted. According to one medical device regulatory guidance, the structural component is expected to have a fatigue life in excess of 600 million cycles under worst case physiologic conditions. Using basic principles for fatigue life evaluation, a constant lifeline for mean stress versus stress amplitude was statistically established. The fundamental model for the analysis was a generalized Weibull distribution for which the parameters were stress-dependent. The model was optimized using maximum likelihood methods and confirmed by chi-squared goodness-of-fit evaluation. The methodology used for this investigation, well established in fatigue engineering, was shown to be equally effective when applied to life science problems, with the potential for benefit to patients.
Using Barkhausen Noise and Digital Image Correlation to Investigate the Influence of Local Residual Stresses on Fatigue-Crack Propagation

Published: June 2016

Abstract
Fatigue-crack propagation is, by far, the most crucial failure mechanism of technical systems. The key to understanding microscopic processes that lead to failure lies in the knowledge of local stresses, the driving force of cracks. We present the mapping of stress and strain fields induced by a single overload on a fatigue crack and their influence on transient crack-growth retardation. In contrast to former work, in which synchrotron x-ray diffraction (XRD) was used, this investigation was performed by using a calibrated magnetic Barkhausen noise microscope in combination with digital image correlation based on in situ scanning electron microscope imaging. The underlying mechanisms, residual stress effects in front of the crack tip and plasticity-induced crack closure caused by the plastic wake, have been studied. Specifically, a crack in S960Q steel has been followed through the overload (OL) region while examining measurements at distinctive overload points: before OL, after OL, at maximum retardation, and at recovery. We observe a strong correlation of the local fatigue-crack-growth rate with the local residual stress distribution obtained from magnetic Barkhausen noise, which remains nearly unchanged after the crack has passed by. Digital image correlation results reveal the influence of these residual stresses on crack-tip opening reactions and strain fields under external loads. Although strain fields show a strong decrease because of the OL event, differences in crack opening stresses remain rather low at first, but prevail in the second part of the OL region. The applicability of new measurement methods and their results regarding the dominating retardation mechanism are discussed. These indicate that the residual stress effect on the strain fields can be associated to be more significant than plasticity-induced crack closure at maximum retardation with a change of mechanisms on reacceleration.
“Say, What is Honor?”
Authors: Kantor Jamison 
Published: June 2016

Jamison Kantor, “‘Say, What is Honor?’: Wordsworth and the Value of Honor” (pp. 1–36)
Instead of reading the poetry of William Wordsworth’s “great decade” (1798–1808) as a struggle between nature and Milton, Rousseau and Burke, or history and the imagination, this essay suggests that it can also be characterized by an internal tension within a keyword of the romantic age: honor. Romantic honor could connote hierarchy and status—which, I argue, functioned in an emerging market for “dignified” literary productions. But it could also be a progressive value of egalitarianism and equity, one that allowed poetry to appeal to the “native and naked dignity” inherent in all people regardless of their economic status. Working off of recent scholarship that considers the role of honor in modernity, this essay explores how Wordsworth’s poetry used the virtue to stage a paradox that endures within liberal society: the conflict between market distinction and social equality. Focusing on honor as a sign for both qualities might thus reveal Wordsworth’s poetry as a register for the influence—and impasses—of liberal politics on European aesthetics.
Kant with Bartleby
Authors: Yoshikuni Hiroki 
Published: June 2016

Hiroki Yoshikuni, “Kant with Bartleby: A Fate of Freedom” (pp. 37–63)
This essay explores the problem of the “unaccountable” in Herman Melville’s “Bartleby, the Scrivener” (1856) in light of the Kantian idea of freedom. The lawyer-narrator declares his own inability to tell a story of Bartleby, but by doing so he also emphasizes the scrivener’s accountableness, by which Bartleby is presented as a character of exceptional originality. Bartleby might thus appear free in the Kantian sense, because his unaccountableness suggests that the determining ground of his will is not determined by inclinations in nature but is independent from it. But, pointing out that this construction of Bartleby is based on unaccountableness that ends up in nothing but the modern notion of individualism or subjectivity, which is not freedom as such but a fantasy of freedom, I argue that Bartleby destroys precisely such subjectivity by his thing-like immobility. The lawyer cannot decide at last whether Bartleby is a human subject or a piece of furniture fixed in his office.
Politics for the Polyps
Authors: Harris Daniel 
Published: June 2016

Daniel Harris, “Politics for the Polyps: The Compound Organism as a ‘Peculiar Form of Communism’ in Charles Kingsley’s Alton Locke and The Water-Babies” (pp. 64–88)
Charles Kingsley’s novels and political writings are saturated with references to physiological processes in marine invertebrates. In particular, the forms of his novels take their inspiration from functional arrangements in colonial organisms such as corals, in which “individual” polyps are physiologically linked to their neighbors. Alton Locke (1851) and The Water-Babies (1863) attempt to explain the benefits of cooperative economic practices (e.g., the associative workshop) and the dangers of cooperative political practices (e.g., the Chartist mass meeting) by jettisoning British Enlightenment assumptions about personal identity. Instead, Kingsley’s novels use discontinuous and communal physiological processes in invertebrates, such as corals and jellyfish, as frameworks for representing psychological and political development. Ultimately, Kingsley seeks to intervene in mid-century debates about how to individuate members of the working class by suggesting that reformist measures must be grounded in a physiological understanding of individuation that contravenes psychological definitions of individuality.

Published: June 2016

Aims
Elevated sex hormone-binding globulin (SHBG) concentrations have been described in patients with type 1 diabetes mellitus (T1DM), probably due to low portal insulin concentrations. We aimed to investigate whether the route of insulin administration, continuous intraperitoneal insulin infusion (CIPII), or subcutaneous (SC), influences SHBG concentrations among T1DM patients.

Methods
Post hoc analysis of SHBG in samples derived from a randomized, open-labeled crossover trial was carried out in 20 T1DM patients: 50% males, mean age 43 (±13) years, diabetes duration 23 (±11) years, and hemoglobin A1c (HbA1c) 8.7 (±1.1) (72 (±12) mmol/mol). As secondary outcomes, testosterone, 17-β-estradiol, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) were analyzed.

Results
Estimated mean change in SHBG was −10.3nmol/L (95% CI: −17.4, −3.2) during CIPII and 3.7nmol/L (95% CI: −12.0, 4.6) during SC insulin treatment. Taking the effect of treatment order into account, the difference in SHBG between therapies was −6.6nmol/L (95% CI: −17.5, 4.3); −12.7nmol/L (95% CI: −25.1, −0.4) for males and −1.7nmol/L (95% CI: −24.6, 21.1) for females, respectively. Among males, SHBG and testosterone concentrations changed significantly during CIPII; −15.8nmol/L (95% CI: −24.2, −7.5) and −8.3nmol/L (95% CI: −14.4, −2.2), respectively. The difference between CIPII and SC insulin treatment was also significant for change in FSH 1.2U/L (95% CI: 0.1, 2.2) among males.

Conclusions
SHBG concentrations decreased significantly during CIPII treatment. Moreover, the difference in change between CIPII and SC insulin therapy was significant for SHBG and FSH among males. These findings support the hypothesis that portal insulin administration influences circulating SHBG and sex steroids.

Abstract

Background.
Subtypes of melanoma, such as mucosal, uveal, and acral, are believed to result in worse prognoses than nonacral cutaneous melanoma. After a diagnosis of distant metastatic disease, however, the overall survival of patients with mucosal, uveal, acral, nonacral cutaneous, and unknown primary melanoma has not been directly compared.

Materials and Methods.
We conducted a single-center, retrospective analysis of 3,454 patients with melanoma diagnosed with distant metastases from 2000 to 2013, identified from a prospectively maintained database. We examined melanoma subtype, date of diagnosis of distant metastases, age at diagnosis of metastasis, gender, and site of melanoma metastases.

Results.
Of the 3,454 patients (237 with mucosal, 286 with uveal, 2,292 with nonacral cutaneous, 105 with acral cutaneous, and 534 with unknown primary melanoma), 2,594 died. The median follow-up was 46.1 months. The median overall survival for those with mucosal, uveal, acral, nonacral cutaneous, and unknown primary melanoma was 9.1, 13.4, 11.4, 11.7, and 10.4 months, respectively. Patients with uveal melanoma, cutaneous melanoma (acral and nonacral), and unknown primary melanoma had similar survival, but patients with mucosal melanoma had worse survival. Patients diagnosed with metastatic melanoma in 2006–2010 and 2011–2013 had better overall survival than patients diagnosed in 2000–2005. In a multivariate model, patients with mucosal melanoma had inferior overall survival compared with patients with the other four subtypes.

Conclusion.
Additional research and advocacy are needed for patients with mucosal melanoma because of their shorter overall survival in the metastatic setting. Despite distinct tumor biology, the survival was similar for those with metastatic uveal melanoma, acral, nonacral cutaneous, and unknown primary melanoma.
¿EDUCAMOS PARA LA SOLIDARIDAD? REFLEXIONES ANTROPOEDUCATIVAS DE UN PROFESOR ENTROPIZADO.

Vivimos en el mundo del consumismo. Dilapidamos cultura, al igual que las relaciones, y los valores también se han convertido en objeto de dispendio. En la rutina educativa, el ritmo y presiones a las que se ve sometido el docente imposibilita una transformación por medio de la acción pedagógica, quedando contenidos y valores en meros compartimentos vacíos de toda cavilación. Por esta razón, se hace necesario un proceso reflexivo acerca del papel que está jugando la educación actual en la conformación de los ciudadanos del mañana, así como de sus propias señas de identidad.

En este estudio se analizan las metáforas personales y emocionales sobre el profesor y el aprendizaje del alumnado de Tecnología de una muestra de estudiantes del Máster de Secundaria de formación del profesorado de la Universidad de Extremadura (España). El procedimiento de recogida de datos fue un cuestionario abierto donde tenían que describir sus metáforas y realizar un dibujo de ellas. En la investigación realizada adaptamos las cuatro categorías de Leavy et al. (2007): conductistas-transmisivas, cognitivas-constructivistas, situadas y autorreferenciadas. Los resultados indican que en las metáforas generales en cuanto al rol del profesor, el mayor número se encuentran en la categoría conductista transmisiva seguida de las cognitiva/constructivista. Con respecto al aprendizaje de los alumnos destaca la categoría de metáforas cognitivas-constructivistas. Existe una cierta coherencia entre las relacionadas con el profesor y las del aprendizaje pero éstas presentan metáforas más negativas. En las metáforas emocionales tanto en el rol de profesor como en el aprendizaje de los alumnos, destacan las metáforas cognitivas-constructivistas seguidas de las conductistas, pero éstas reflejan emociones más negativas. Se han expresado emociones básicas y sociales, positivas, negativas y neutras.

En este estudio nos hemos propuesto analizar esta capacidad predictiva de la ira sobre la ansiedad escolar en una muestra de 1131estudiantes chilenos de Educación Secundaria, 560 chicos y 571 chicas (49,51% y 51,49%, respectivamente) todos ellos con edades comprendidas entre los 13 y los 18 años (M=15.30; DE=1.10). La expresión de la ira se midió con el State-Trait Anger Expression Inventory for Children and Adolescents (STAXI-NA) y la Ansiedad Escolar con el Inventario de Ansiedad Escolar (IAES). Los análisis de regresión logística revelaron que altas puntuaciones en sentimientos de ira, temperamento de ira, expresión interna de ira, ira-estado e ira-rasgo predicen la alta ansiedad. Estos resultados sugieren la necesidad de diseñar y desarrollar programas educativos que ayuden a los estudiantes a canalizar la expresión de la ira y disminuyan los niveles de ansiedad escolar.
