Authors: Nicol Marion , Alexandre Stéphane , Luizet Jean-Baptiste , Skogman Malena , Jouenne Thierry , Salcedo Suzana , Dé Emmanuelle
Published: January 2018

The increasing threat of Acinetobacter baumannii as a nosocomial pathogen is mainly due to the occurrence of multidrug-resistant strains that are associated with the real problem of its eradication from hospital wards. The particular ability of this pathogen to form biofilms contributes to its persistence, increases antibiotic resistance, and promotes persistent/device-related infections. We previously demonstrated that virstatin, which is a small organic compound known to decrease virulence of Vibrio cholera via an inhibition of T4-pili expression, displayed very promising activity to prevent A. baumannii biofilm development. Here, we examined the antibiofilm activity of mono-unsaturated chain fatty acids, palmitoleic (PoA), and myristoleic (MoA) acids, presenting similar action on V. cholerae virulence. We demonstrated that PoA and MoA (at 0.02 mg/mL) were able to decrease A. baumannii ATCC 17978 biofilm formation up to 38% and 24%, respectively, presented a biofilm dispersing effect and drastically reduced motility. We highlighted that these fatty acids decreased the expression of the regulator abaR from the LuxIR-type quorum sensing (QS) communication system AbaIR and consequently reduced the N-acyl-homoserine lactone production (AHL). This effect can be countered by addition of exogenous AHLs. Besides, fatty acids may have additional non-targeted effects, independent from QS. Atomic force microscopy experiments probed indeed that PoA and MoA could also act on the initial adhesion process in modifying the material interface properties. Evaluation of fatty acids effect on 22 clinical isolates showed a strain-dependent antibiofilm activity, which was not correlated to hydrophobicity or pellicle formation ability of the tested strains, and suggested a real diversity in cell-to-cell communication systems involved in A. baumannii biofilm formation.

Published: January 2018

Cutaneous squamous cell carcinomas (SCC) affecting the regions of the head and neck can be challenging to resect surgically and refractory to chemotherapy or radiation therapy. Consequently; the treatment of squamous cell carcinomas of the skin is a focus of current research. One such advancement is immunotherapy. Herein we describe clinical remission of invasive, poorly differentiated squamous cell carcinoma of the pre-auricular region with external auditory canal involvement using cetuximab, an epidermal growth factor receptor (EGFR) antibody; and nivolumab, a programmed death receptor-1 (PD-1) antibody. Such durable and comprehensive disease resolution demonstrates the therapeutic potential of cetuximab and nivolumab in surgically challenging, treatment-resistant cutaneous squamous cell carcinoma.
Achieving High Strength and Good Ductility in As-Extruded Mg–Gd–Y–Zn Alloys by Ce Micro-Alloying
Authors: Gao Zhengyuan , Hu Linsheng , Li Jinfeng , An Zhiguo , Li Jun , Huang Qiuyan
Published: January 2018

In this study, the effect of Ce additions on microstructure evolution of Mg–7Gd–3.5Y–0.3Zn (wt %) alloys during the casting, homogenization, aging and extrusion processing are investigated, and novel mechanical properties are also obtained. The results show that Ce addition promotes the formation of long period stacking ordered (LPSO) phases in the as-cast Mg–Gd–Y–Zn–Ce alloys. A high content of Ce addition would reduce the maximum solubility of Gd and Y in the Mg matrix, which leads to the higher density of Mg12Ce phases in the as-homogenized alloys. The major second phases observed in the as-extruded alloys are micron-sized bulk LPSO phases, nano-sized stripe LPSO phases, and broken Mg12Ce and Mg5RE phases. Recrystallized grain size of the as-extruded 0.2Ce, 0.5Ce and 1.0Ce alloys can be refined to ~4.3 μm, ~1.0 μm and ~8.4 μm, respectively, which is caused by the synthesized effect of both micron phases and nano phases. The strength and ductility of as-extruded samples firstly increase and then decrease with increasing Ce content. As-extruded 0.5Ce alloy exhibits optimal mechanical properties, with ultimate strength of 365 MPa and ductility of ~15% simultaneously.
Relating Topological and Electrical Properties of Fractured Porous Media: Insights into the Characterization of Rock Fracturing
Authors: Roubinet Delphine , Irving James , Pezard Philippe
Published: January 2018

Numerous laboratory and field experiments suggest that electrical properties of fractured rocks may provide critical information regarding the topological properties of the underlying fracture networks. However, a lack of numerical studies dedicated to realistic fractured media prevents us from assessing, in a systematic manner, the relationships between electrical and topological properties in complex domains for which a representative elementary volume may not exist. To address this issue, we conduct an extended numerical analysis over a large range of realistic fractured porous media with an explicit description of the fractures that takes into account the fracture–matrix interactions. Our work shows that the fracture density determines the suitability of Archie’s law for describing effective electrical properties with complex behavior associated with small fracture densities. In particular, for fracture networks at the percolation threshold surrounded by a low-porosity matrix, the effective petrophysical relationships are impacted by the assumed fracture-length distribution and the exchange of electric current between the fractures and surrounding matrix. These results help in understanding experimental observations that were difficult to explain so far, suggesting that the effective electrical properties of fractured rock may be used to obtain insights into the properties of their geological structures.

Published: January 2018

The aim of this study was the purification process of polyphenols from Aronia melanocarpa (chokeberry), and the purification parameters were optimised by adsorption and desorption tests. By comparing adsorption and desorption ability of polyphenols from chokeberry on six kinds of macroporous resin, XAD-7 resin was selected. Experiments prove that the best purification parameters of static adsorption and desorption were sample pH = 4.0 with 4 h of adsorption; and desorption solvent is 95% ethanol (pH = 7.0) with 2 h of desorption. The best dynamic parameters were 9.3 bed volume (BV) of sample loading amount at a feeding flow rate of 2 BV/h, and washing the column with 5.8 BV of water, followed by subsequent elution with an eluent volume of 5.0 mL at an elution flow rate of 2 BV/h. Next the antioxidant and antiproliferative activity of polyphenols from chokeberry, blueberries, haskap berries was studied on HepG2 human liver cancer cells. The results show that polyphenol from chokeberry has a strong antioxidant effect. Taking into account the content of polyphenols in fruit, polyphenols from chokeberry represent a very valuable natural antioxidant source with antiproliferative products.
Nitrogen Nutrition of Fruit Trees to Reconcile Productivity and Environmental Concerns
Authors: Carranca Corina , Brunetto Gustavo , Tagliavini Massimo
Published: January 2018

Although perennial fruit crops represent 1% of global agricultural land, they are of a great economic importance in world trade and in the economy of many regions. The perennial woody nature of fruit trees, their physiological stages of growth, the root distribution pattern, and the presence of herbaceous vegetation in alleys make orchard systems efficient in the use and recycling of nitrogen (N). The present paper intends to review the existing literature on N nutrition of young and mature deciduous and evergreen fruit trees with special emphasis to temperate and Mediterranean climates. There are two major sources of N contributing to vegetative tree growth and reproduction: root N uptake and internal N cycling. Optimisation of the use of external and internal N sources is important for a sustainable fruit production, as N use efficiency by young and mature fruit trees is generally lower than 55% and losses of fertilizer N may occur with the consequent economic and environmental concern. Organic alternatives to mineral N fertilizer like the application of manure, compost, mulching, and cover crops are scarcely used in perennial fruit trees, in spite of the fact that society’s expectations call for more sustainable production techniques and the demand for organic fruits is increasing.

Authors: Li Yongyan , Hu Guangwei
Published: January 2018

As a response to intensified globalization, international research collaboration has become common in the social sciences. This paper reports a study that examined what Chinese management academics and their overseas counterparts perceived to be the benefits and challenges arising from research collaboration with each other. Data collected with two parallel questionnaires administered, respectively, to 114 Chinese and 30 overseas management academics revealed a variety of perceived benefits relating mainly to Chinese and overseas academics’ complementing strengths. Analysis of the same data also identified an array of perceived challenges stemming from a combination of cultural, epistemological, ideological, linguistic, institutional, and relational differences. Our study generated insights to be drawn upon in policy-making and in the coordination of international research collaboration.
A New Localization System for Indoor Service Robots in Low Luminance and Slippery Indoor Environment Using Afocal Optical Flow Sensor Based Sensor Fusion
Authors: Yi Dong-Hoon , Lee Tae-Jae , Cho Dong-Il
Published: January 2018

In this paper, a new localization system utilizing afocal optical flow sensor (AOFS) based sensor fusion for indoor service robots in low luminance and slippery environment is proposed, where conventional localization systems do not perform well. To accurately estimate the moving distance of a robot in a slippery environment, the robot was equipped with an AOFS along with two conventional wheel encoders. To estimate the orientation of the robot, we adopted a forward-viewing mono-camera and a gyroscope. In a very low luminance environment, it is hard to conduct conventional feature extraction and matching for localization. Instead, the interior space structure from an image and robot orientation was assessed. To enhance the appearance of image boundary, rolling guidance filter was applied after the histogram equalization. The proposed system was developed to be operable on a low-cost processor and implemented on a consumer robot. Experiments were conducted in low illumination condition of 0.1 lx and carpeted environment. The robot moved for 20 times in a 1.5 × 2.0 m square trajectory. When only wheel encoders and a gyroscope were used for robot localization, the maximum position error was 10.3 m and the maximum orientation error was 15.4°. Using the proposed system, the maximum position error and orientation error were found as 0.8 m and within 1.0°, respectively.

Authors: Aranki Daniel , Peh Gao , Kurillo Gregorij , Bajcsy Ruzena
Published: January 2018

Studies have shown that about half of the injuries sustained during long-distance running involve the knee. Cadence (steps per minute) has been identified as a factor that is strongly associated with these running-related injuries, making it a worthwhile candidate for further study. As such, it is critical for long-distance runners to minimize their risk of injury by running at an appropriate running cadence. In this paper, we present the results of a study on the feasibility and usability of RunningCoach, a mobile health (mHealth) system that remotely monitors running cadence levels of runners in a continuous fashion, among other variables, and provides immediate feedback to runners in an effort to help them optimize their running cadence.
Combined Layer/Particle Approaches in Surface Molecular Imprinting of Proteins: Signal Enhancement and Competition
Authors: Phan Nam , Sussitz Hermann , Ladenhauf Eva , Pum Dietmar , Lieberzeit Peter
Published: January 2018

Herein we report novel approaches to the molecular imprinting of proteins utilizing templates sizing around 10 nm and some 100 nm. The first step comprised synthesizing nanoparticles of molecularly imprinted polymers (MIP) towards bovine serum albumin (BSA) and characterizing them according to size and binding capacity. In a second step, they were utilized as templates. Quartz crystal microbalances (QCM) coated with MIP thin films based on BSA MIP nanoparticles lead to a two-fold increase in sensor responses, compared with the case of directly using the protein as the template. This also established that individual BSA molecules exhibit different “epitopes” for molecular imprinting on their outer surfaces. In light of this knowledge, a possible MIP-based biomimetic assay format was tested by exposing QCM coated with BSA MIP thin films to mixtures of BSA and imprinted and non-imprinted polymer (NIP) nanoparticles. At high protein concentrations (1000 ppm) measurements revealed aggregation behavior, i.e., BSA binding MIP NP onto the MIP surface. This increased sensor responses by more than 30% during proof of concept measurements. At lower a BSA concentration (500 ppm), thin films and particles revealed competitive behavior.
Learning Outcomes in an Introductory Sociology Course: The Role of Learning Approach, Socio-Demographic Characteristics, Group and Teacher Effects
Authors: Miskolczi Péter , Rakovics Márton
Published: January 2018

The article discusses a study on learning outcomes in an introductory Sociology course in a higher education setting. A quantitative model similar to education production functions is hypothesized. Independent variables include socio-demographic and psychological ones, as well as others pertaining to the learning environment. Learning is measured with the binary categories of “deep” and “surface” outcomes, which are qualitatively different, and are based on the comparison of mind maps drawn by students at the beginning and end of their first semester. Questionnaire data was collected from 264 first-year students of a Social Science Faculty. Significant effects on learning outcome are found for family background, major area of study, and teacher’s gender.
Cameron, Conservatives and a Christian Britain: A Critical Exploration of Political Discourses about Religion in the Contemporary United Kingdom
Authors: Allen Chris
Published: January 2018

In the British setting, the deployment of the phrase ‘doing god’ has become increasingly common to refer to an emerging trend whereby religion has acquired an increasingly prominent role in political spaces and discourses. This was particularly prominent while David Cameron was Prime Minister and leader of the Conservative Party. While historically, religion has not had a prominent place in either the former Prime Minister David Cameron. Here, the findings from critical analyzing a series of Cameron’s public pronouncements about religion—and Christianity in particular—is set out to try and better understand his own adherence to Christianity (the personal) how this intersected with his politics and role as Prime Minister (the political), and more importantly how this shaped his views about Britain being a Christian country (the national). Contextualized within the embryonic scholarly literature relating to the phenomenon of ‘doing god’ in the contemporary British setting, this article concludes by considering alternative and analogous frames through which greater elucidation of the true motivations of his pronouncements might be understood.

Published: January 2018

Burkholderia mallei is a host-adapted Gram-negative mammalian pathogen that causes the severe disease glanders. Glanders can manifest as a rapid acute progression or a chronic debilitating syndrome primarily affecting solipeds and humans in close association with infected animals. In USA, B. mallei is classified as one of the most important bacterial biothreat agents. Presently, there is no licensed glanders vaccine available for humans or animals. In this work, outer membrane vesicles (OMVs) were isolated from three attenuated biosafe bacterial strains, Burkholderia pseudomallei Bp82, B. thailandensis E555, and B. thailandensis TxDOH and used to vaccinate mice. B. thailandensis OMVs induced significantly higher antibody responses that were investigated. B. mallei specific serum antibody responses were of higher magnitude in mice vaccinated with B. thailandensis OMVs compared to levels in mice vaccinated with B. pseudomallei OMVs. OMVs derived from biosafe strains protected mice from acute lethal glanders with vesicles from the two B. thailandensis strains affording significant protection (>90%) up to 35 days post-infection with some up to 60 days. Organ loads from 35-day survivors indicated bacteria colonization of the lungs, liver, and spleen while those from 60 days had high CFUs in the spleens. The highest antibody producing vaccine (B. thailandensis E555 OMVs) also protected C57BL/6 mice from acute inhalational glanders with evidence of full protection.
Improvement of Hydroclimatic Projections over Southeast Spain by Applying a Novel RCM Ensemble Approach
Authors: Olmos Giménez Patricia , García-Galiano Sandra , Giraldo-Osorio Juan
Published: January 2018

Climate model outputs can be used as climate forcing for hydrological models to study the impact of climate change on the water cycle. This usually propagates cumulative uncertainties, transferring the errors from the climate models to the hydrological models. Then, methodologies are needed to evaluate the impact of climate change at basin scale by reducing the uncertainties involved in the modeling chain. The paper aims to assess the impact of climate change on the runoff, considering a novel approach to build a Regional Climate Model (RCM) ensemble as climate forcing for a parsimonious spatially distributed hydrological model. A semiarid basin of southeast of Spain was selected for the study. The RCM ensembles were built based on seasonal and annual variability of rainfall and temperature. If the runoff projections for 2021–2050 are compared to the 1961–1990 observed period, a significant decrease in runoff equal to −20% (p-value t-test 0.05) was projected. However, by changing the observed period to 1971–2000, a despicable change (2.5%) is identified. This fact demonstrates that trends based on short records are very sensitive to the beginning and end dates, due to the natural variability. Special attention should be paid to the selection of the period for impact studies.
Outcome of Repair of Distal Radial and Ulnar Fractures in Dogs Weighing 4 kg or Less Using a 1.5-mm Locking Adaption Plate or 2.0-mm Limited Contact Dynamic Compression Plate
Authors: Nelson Thomas , Strom Adam
Published: January 2018

Objectives Retrospective evaluation of repairing distal radial and ulnar fractures in small breed dogs with the Synthes 1.5-mm locking Adaption plate system and compare results in a similar group of patients repaired with the Synthes 2.0-mm limited contact-dynamic compression plate (LC-DCP).

Methods Electronic medical records from one specialty referral centre were reviewed from March 21, 2010, to October 9, 2015, for patients weighing less than or equal to 4 kg that had a distal one-third radial and ulnar fracture repaired with a Synthes 1.5-mm locking adaption plate or Synthes 2.0-mm LC-DCP. Further inclusion criteria included application of the plate to the cranial surface of the radius via open reduction and internal fixation.

Results Six 1.5-mm Adaption plates and 7 2.0-mm LC-DCPs were used to repair 13 distal radial and ulnar fractures in 12 dogs. There were three major complications in the 1.5-mm adaption plate group (one plate fracture, one screw pull-out and one fracture through a distal screw hole) and one major complication in the 2.0-mm LC-DCP group due to a re-fracture. All patients without a complication had good or excellent functional outcome.

Clinical Significance The authors recommend that the 1.5-mm Adaption plate be used only when a 2.0-mm LC-DCP would not allow for a minimum of two screws in the distal segment and at the discretion of the surgeon.

Authors: Katz Erin , Scott Ruth , Thomson Christopher , Mesa Eileen , Evans Richard , Conzemius Michael
Published: January 2018

Objective To determine if environmental variables affect the average daily activity counts (AC) of dogs with osteoarthritis (OA) and/or owners’ perception of their dog’s clinical signs or quality of life.

Methods The AC and Canine Brief Pain Inventory (CBPI) owner questionnaires of 62 dogs with OA were compared with daily environmental variables including the following: average temperature (°C), high temperature (°C), low temperature (°C), relative humidity (%), total precipitation (mm), average barometric pressure (hPa) and total daylight hours.

Results Daily AC significantly correlated with average temperature and total daylight hours, but average temperature and total daylight hours accounted for less than 1% of variation in AC. No other significant relationships were found between daily AC and daily high temperature, low temperature, relative humidity, total precipitation or average barometric pressure. No statistical relationship was found between daily AC and the CBPI, nor between environmental variables and the CBPI. Canine Brief Pain Inventory scores for pain severity and pain interference decreased significantly over the test period.

Clinical Significance The relationship between daily AC and average temperature and total daylight hours was significant, but unlikely to be clinically significant. Thus, environmental variables do not appear to have a clinically relevant bias on AC or owner CBPI questionnaires. The decrease over time in CBPI pain severity and pain interference values suggests owners completing the CBPI in this study were influenced by a caregiver placebo effect.
Osteochondroma. An Osteological Study
Authors: Ferreira Arquez Humberto
Published: January 2018

Background: Osteochondroma is the most common tumor of bone, accounting for approximately one third of benign lesions in the skeleton is a broad (sessile) or narrow (pedunculated) skeletal protrusion comprised of marrow and cortical bone. Although it is benign, its biological behavior still has a malignant potential. Chondrosarcoma arising in osteochondroma has been recognized for many years. Osteochondromas might occur on any bone preformed in cartilage, they were especially seen on the long bones of the extremities, predominantly around the knee. In fact, the lower limb seemed to be at a higher risk of the tumor than the upper limb on the top two locations: distal part of the femur and proximal part of the tibia, however, the proximal humerus ranked the third place for solitary osteochondroma while the proximal fibula for multiples osteochondromas.

Methods and Findings: A total of 20 skeletons and 18 cadavers of both sex, 16 males and 2 females, with different age groups were used, this study was carried out by routine dissection classes for undergraduate medical student´s in the Morphology Laboratory of the University of Pamplona during the years 2013-2016. In only one sample was found the presence of osteochondroma. The measurement of the osseous mass was of 7 x 3.5 x 1.5 cm, attached to the posterolateral aspect of the middle third of the femur.

Conclusions: Osteochondroma is generally asymptomatic or discovered accidentally, but it can cause different symptoms depending on site of occurrence local swelling, bony deformities, fracture, bursa formation, arthritis and impingement on adjacent tendons, vascular or neurologic compromise, and dislocation The importance of correct treatment and follow-up of large osteochondromas to avoid complications such as further damage to neighboring neurovascular structures, and potential malignant degeneration. The present study describe a rare location from an osteochondroma in the femur diaphysis.

Introduction: The aim of this study was to asses the surveillance of influenza A/other respiratory viruses and risk factors in hospitalized children with the symptoms of influenza-like illness during two consecutive influenza seasons.

Methodology: All children hospitalized with adiagnosis of influenza-like illness had been investigated for Influenza A and other respiratory antigens in pharengeal/nasopharyngeal secretions.

Results: A total of 132 hospitalized children between December 2013-May 2014 and December 2014-May 2015 were enrolled in this study. At least one respiratory virus was found to be positive by RT-PCR in 78 (59%) patients, influenza A (H3N2) was detected in only 8 (6%) patients. In 54 (41%) patients samples no respiratory viral pathogen was detected and in 70 (53%) patients, one non- influenza A virus was detected. The respiratory viral pathogens detected in decreasing rates were:RSV (n = 46, 35%), HCoV (n = 10, 7.5%), adenovirüs (n = 7, 5%), rhinovirüs (n = 6, 4.5%), HMPV (n = 5, 4%), Influenza B (n = 4, 3%) ve human Bocavirus (n = 2, 1.5%). In 10 patients, coinfection was detected, however none was with H3N2. In the H3N2 (+) group, the following risk factors were identified: age older than three years (p < 0.05), asthma history (p < 0.05) and chronic lung diseases (p < 0.05).

Conclusion: Influenza A virus was detected in 6% of hospitalized patients with influenza-like illness. Viruses other then Influenza, especially RSV, can cause similar symptoms compatible with Influenza-like-illness.
Les associations au service des politiques de l’emploi : genèse du dispositif local d’accompagnement
Authors: Cottin-Marx Simon
Published: January 2018

Résumé Depuis les années 1980, le monde associatif connaît une importante salarisation. Si cette dynamique est en partie le résultat de la recomposition de l’État providence, cet article montre que les associations ont aussi bénéficié des politiques visant la résorption du chômage. En revenant sur l’histoire des politiques de l’emploi, et à travers l’étude d’un dispositif public visant la professionnalisation du monde associatif employeur, le dispositif local d’accompagnement, l’auteur observe que l’État va progressivement moins s’intéresser aux associations en raison du but d’utilité sociale qu’elles poursuivent. En revanche, son intérêt va de plus en porter sur le rôle qu’elles jouent dans l’économie, sur leur capacité à mobiliser des ressources privées et marchandes et sur leur capacité à développer de l’emploi.
Un étranger en soi. Groupe analytique en cothérapie et psychose au long cours
Authors: Toliou Anastasia
Published: January 2018

Cet article traite la question de l’étranger à travers la clinique de la psychose et la prise en charge psychothérapeutique groupale en cothérapie. Dans un premier temps l’auteur relie la notion de l’étranger à celle de l’identité soulignant les failles de la construction subjective dans le fonctionnement psychotique. Dans un deuxième temps, l’auteur interroge la fonction du groupe analytique dans la prise en charge de cette population et notamment le choix de la cothérapie en tant que dispositif. L’auteur discute la fonction défensive de ce choix tant pour le professionnel qui l’institue que pour l’institution, visant la maîtrise de ce qui cherche à rester étranger pour le sujet et la collectivité. Par la suite, l’auteur discute la fonction créative de ce choix pour le traitement des patients psychotiques en mettant en avant l’utilisation de l’analyse inter-transférentielle permettant de saisir une partie de ce qui semble étrange et étranger dans la rencontre avec le sujet psychotique.
Le concept de groupe d’appartenance et le problème de migration des concepts
Authors: Kaës René
Published: January 2018

Le concept de groupe d’appartenance occupe une place centrale dans la pensée et dans la théorie psychanalytique des groupes de J.C. Rouchy. L’article en décrit les principales dimensions, et comment il se rapproche et se différencie de l’« aire d’appartenance » (C. Neri) et du « sentiment d’appartenance » (A. Correale). L’analyse de ce concept offre un bon exemple du travail de la création conceptuelle et des problèmes épistémologiques qu’elle pose, lorsque cette création prend la forme d’une migration d’un concept créé dans une discipline (ici la sociologie et la psychologie sociale) et transféré dans une autre, en l’occurrence celui de la psychanalyse. L’attention de l’auteur se porte sur le fait que, dans les théories sociologiques et psychosociologiques des groupes, le concept de groupe d’appartenance fait couple avec celui de groupe de référence. Or il n’a pas fait l’objet d’un travail de « naturalisation » (S. Moscovici) analogue à celui qui a transformé le concept de groupe d’appartenance. Pourtant plusieurs caractéristiques de ce second concept, articulé au premier, pourraient présenter quelque intérêt s’ils étaient élaborés dans le champ de la psychanalyse des groupes.
Des dominants à la barre
Authors: Spire Alexis
Published: January 2018

Resume À partir de l'observation de quatre procès pour fraude fiscale, cette contribution montre comment les justiciables du haut de l'échelle sociale gèrent la contrainte juridique, la maîtrisent et, éventuellement, la retournent à leur profit. L'analyse de la scénographie pénale révèle que le rituel judiciaire peine à transformer ces prévenus en délinquants. Ils mettent à distance la contrainte juridique en faisant valoir leurs mérites et leurs compétences, de façon à euphémiser leur délit. L'étude des stratégies de défense révèle des variations en fonction du genre : les femmes justifient leurs actes par l'argument familial tandis que les hommes mettent en avant une compétence professionnelle ou une fibre patriotique. Dans les deux cas, l'enjeu est d'utiliser l'arme du droit pour mettre en scène la violence de l'État et se présenter comme victimes de l'arbitraire de l'administration.
Bound state inequality from the spinless Salpeter equation with the Yukawa potential
Authors: Chen Jiao-Kai
Published: January 2018

In this paper, we discuss the bound-state problem for the spinless Salpeter equation with the Yukawa potential. Due to the nonlocal term of the Hamiltonian encountered, we use the eigenfunction for the ground state of the hydrogen atom as a trial function and employ the variational method to solve the spinless Salpeter equation. We derive the upper bounds on the eigenvalues to obtain the bound state inequality. The constraint on the interaction strength α is given, (2.42m–1.32μ)μ/(2.37m2–mμ) ≤ α < 8/(3π). And the maximum of the screening parameter of the Yukawa potential μ is obtained, μmax = 1.14 m.
Investigating the “kink” plot as a signal of the onset of deconfinement
Authors: Naskręt Michał
Published: January 2018

One of the physics goals of the NA61/SHINE collaboration at the CERN Super Proton Synchrotron is to study the phase diagram of hadronic matter. To this end, a series of heavy ion collision measurements are performed. It is believed that above a certain collision energy and system size a phase transition between the hadronic matter and quark–gluon plasma occurs. A number of observables have been developed to determine which of the phases was created at the early stage of the collision. This report discusses the dependence of the ratio of the mean number of produced pions to the mean number of wounded nucleons on the Fermi energy measure. For comparison with other measurements this is often presented in the form of the “kink” plot. This plot is presented enriched with preliminary results for 40Ar+45Sc central collisions at 13A, 19A, 30A, 40A, 75A and 150A GeV/c beam momenta. The results are finally compared to data from other experiments.

La persecución inquisitorial contra los judíos no ha sido un tema abordado sistemáticamente por la historiografía, porque las investigaciones sobre la represión de los tribunales inquisitoriales en el tránsito entre los siglos XV y XVI se han centrado en el grupo judeoconverso. Y si bien es cierto que la Inquisición moderna utilizó algunos procesamientos a hebreos de manera ejemplarizante para resaltar el peligro que representaban para la comunidad cristiana, y que han sido recogidos posteriormente por los investigadores, el caso de Salomó Saporta ha sido estudiado y comentado como un caso aislado. Por esa razón quizás sea el momento de plantear la necesidad de estudiar los mecanismos coercitivos contra la comunidad judía peninsular de manera más general. Un primer paso, modesto, puede ser el análisis de la persecución que sufrió Salomó Saporta durante la segunda mitad de la década de 1480.

Com o envelhecimento da população brasileira, há um aumento da vulnerabilidade, riscos de agravos e prevalência de doenças crônicas, aumentando o número de idosos acamados, fragilizados, com elevado grau de dependência. Objetivou-se identificar os estímulos que atuam no idoso acamado, estabelecer os diagnósticos de enfermagem e intervenções que auxiliem na promoção de respostas adaptativas. Trata-se de um relato de experiência realizado durante o acompanhamento a um idoso acamado por sequelas de AVC. Utilizou-se um roteiro de levantamento de dados baseado no Modelo de Adaptação de Roy. Na avaliação de comportamentos e estímulos reconheceram-se os diagnósticos: risco da síndrome do desuso, risco de aspiração, incontinência urinária reflexa, integridade da pele prejudicada, déficit no autocuidado e conforto prejudicado. Por meio das intervenções de enfermagem, os principais resultados obtidos foram: melhora da rigidez muscular e redução do diâmetro da úlcera por pressão. O processo de enfermagem de Roy proporcionou a identificação de estímulos, possibilitando uma assistência mais específica.

Este estudo objetivou apreender potencialidades e limites da visita domiciliar para identificar e abordar mulheres em situação de violência. Trata-se de uma pesquisa participante da qual participaram 38 profissionais (enfermeiros, técnicos de enfermagem e agentes comunitários de saúde) de seis equipes da Estratégia Saúde da Família de um município localizado na região Noroeste do Rio Grande do Sul, Brasil. A produção dos dados ocorreu entre novembro de 2015 e março de 2016, a partir de seis oficinas pedagógicas. Os dados foram analisados mediante análise temática. A visita domiciliar é potencial para identificar situações de violência contra as mulheres e observar as relações conjugais e familiares no ambiente doméstico. Como limites, constatou-se a presença do agressor e de familiares, a sobrecarga de trabalho na unidade e pouco tempo para abordar a questão. Para superá-los, os profissionais apontaram a criação de uma atmosfera privada e segura como proposta a ser efetivada através da persistência e planejamento das visitas. Incluir a visita domiciliar como tecnologia leve-dura voltada às mulheres em situação de violência como rotina na Estratégia Saúde da Família possibilita aprimorá-la como técnica de abordagem do problema.

Estudo descritivo, com delineamento transversal, realizado junto a três unidades de terapia intensiva adulta de um hospital público municipal, em Cuiabá – MT. Teve como objetivo analisar a composição quantitativa e qualitativa do quadro de pessoal de enfermagem destinado à assistência em terapia intensiva, comparativamente às normas específicas do Conselho Federal de Enfermagem. Os dados foram levantados a partir das escalas dos meses de fevereiro a abril de 2016. De posse do material coletado, quando comparados com o cálculo realizado a partir da Resolução COFEN 543/2017, pode-se observar que há um distanciamento e inadequação qualiquantitativa entre a realidade empírica e o que determina a referida resolução relativa ao dimensionamento de pessoal para a assistência em terapia intensiva. No que diz respeito ao exercício profissional, evidenciou-se ainda a inadequada participação de auxiliares de enfermagem na assistência ao paciente que requer cuidados técnicos e de maior complexidade. Frente ao evidenciado, sugere-se a baixa institucionalidade das normas técnicas da enfermagem brasileira no processo de organização do trabalho da enfermagem destinado à pacientes em terapia intensiva.

Authors: Murdjito  , Rosari Maria Putri , Djatmiko Eko Budi
Published: January 2018

Evaluation is carried out on the operability of a 87,900 ton Sevan Stabilized Platform (SSP) functioned as an FPSO in the hypothetical operational site of Masela Block. This is to observe the critical conditions when side-by-side (SBS) offloading is performed between the SSP and a 35,000 DWT shuttle tanker. The first stage of analysis conducted on the moored SSP as a single floating body indicates the capability to withstand a 100-year wave, designated by the significant height of 8.0 m. Largest motions are experienced when SSP contains 75% load capacity, resulting in the mooring tension range from 2,000 kN up to 7,000 kN, portraying ample safety factors of 2.0 up to 3.0. The second stage of analysis is conducted for execution of SBS offloading from SSP to shuttle tanker, positioned in a 3.3 m distance. Observation is made when SSP is loaded with 100%, 83%, and 75% capacities correlated to the shuttle tanker loading of 10%, 60%, and 90% capacities. This reveals critical conditions arise when the wave exceeds 2.0 m in height, or the operability level of some 88.5%. Safer operation and higher operability level could be achieved by increasing the distance of SSP and shuttle tanker.

Controlling and monitoring of ship fuel treatment system is based on the needs of safety and business. Therefore, ship automatic fuel system is a support system recommended by ship classification society, engine manufacture, and shipping company. The new system may give highly efficiency operation and supervision. In this research, we developed marine diesel fuel system interface to monitor how the systems work. Main diesel engine fuel system consist of transfer system, separation system, feed system, and circulation system. The aim of this research is to control and display the shipboard fuel system. All valves, pumps, and separator units were controlled by programmable logic controller using tank level switches as input signal. We have tested this automation system with a computer simulations. As an initial step, valves, pumps, and separator units are successfully controlled and displayed. Based on program simulation, the operational leading time of settling tank and day tank are one hour and 9,8 hours, respectively. It is mean both of one settling tank or day tank are ready before the another tank empty. This system also have detection ability due to system failure.

Published: January 2018

Edge trimming process is needed for finishing CFRP components to the required accuracy and surface quality. The bouncing–back effect of CFRP components is very challenging owing to spring back of trimmed edge after cutting tool pass. Ultrasonic assisted machining (UAM) is an efficient method used to enhance the quality of CFRP parts due to the reduced contact time between the tool and workpiece. This paper experimentally investigates the effect of edge trimming variables on the cutting forces and the magnitude of the bouncing back. Diamond abrasive end mills were utilized during ultrasonic assisted edge trimming of CFRP. The processes variables include spindle speed, feed rate, radial depth of cut, fiber orientations, and up/down strategy. Statistical analysis was conducted to determine the most significant factor on performance characteristics. Regression equation was also developed to predict the value of bouncing back. The results showed that depth of cut and feed rate have a significant effect on bouncing back among the process variables.

Published: January 2018

This paper provides information on the effects of organoclay (OC) impregnation in the thermal, physical and mechanical properties of recycled composite materials. The raw material was a flexible industry trimmings from a food packaging manufacturing plant. Various material testing standards were employed to determine the properties of the recycled materials. Results showed that the recycled material has significant effect in retarding the linear rate of burning due to the yielded ρ – value equal to zero (0). The resistance factors showed that the recycled material is potential as insulation, barrier, or roofing tile. These information is an indication that impregnation of OC enhanced the recycled material to be thermal resistant, gas and water vapor barrier and as potential barrier material.
