Published: September 2018

Abstract
In many chemical engineering processes, a chemical reaction between a foreign mass and the fluid does occur. These processes find relevance in polymer production, oxidation of solid materials, ceramics or glassware manufacturing, tubular reactors, food processing, and synthesis of ceramic materials. Therefore, an exploration of homogeneous first-order chemical reaction effects on heat and mass transfer along with entropy analysis of Jeffrey liquid flow towards a stretched isothermal porous sheet is performed. Fluid is conducting electrically in the company of transverse magnetic field. Variations in heat and mass transfer mechanisms are accounted in the presence of viscous dissipation, heat source/sink and cross-diffusion aspects. The partial differential equations system governing the heat transfer of Jeffery liquid is reformed to the ordinary differential system through relevant transformations. Numerical solutions based on Runge-Kutta shooting method are obtained for the subsequent nonlinear problem. A parametric exploration is conducted to reveal the tendency of the solutions. The present study reveals that the Lorentz force due to magnetism can be used as a key parameter to control the flow fields. Entropy number is larger for higher values of Deborah and Brinkman numbers. It is also established that the concentration species field and its layer thickness of the Jeffery liquid decreases for a stronger chemical reaction aspect. To comprehend the legitimacy of numerical results a comparison with the existing results is made in this exploration and alleged an admirable agreement.

Published: September 2018

Abstract
The main theme of this paper is to investigate entropy generation analysis for unsteady three-dimensional flow of viscous (Newtonian) fluid between two horizontal parallel plates. Lower plate is porous and stretching while upper plate squeezed downward. Further effects of nonlinear thermal radiation, viscous dissipation, heat source/sink and activation energy are accounted. Entropy generation rate calculated in terms of thermal radiation, fluid diffusion and fluid friction. Transformations procedure used lead to reduction of PDE’s into ordinary ones. Built-in-Shooting technique is used for the computational analysis. Impacts of different flow variables on temperature, velocity, concentration, volumetric entropy generation and Bejan number are discussed and presented through graphs. Temperature and concentration gradient are discussed numerically. It is examined from obtained results that velocity of liquid particle decays through larger estimation of squeezing parameter. It is also examined that temperature distribution enhances for higher estimation of radiative heat flux. Moreover temperature and concentration gradient increase for larger squeezing parameter.

Abstract

Background
The association of hyperthyroidism with renal disease is very rare and the importance of timely clinical recognition cannot be overemphasized.

Case presentation
An 11-year-old girl presented with gastrointestinal symptoms while hypertension, edema and abdominal pain were noticed on clinical examination. Laboratory investigation revealed: hemoglobin 9.4 (11.5–15.5) g/dL, total white cell count 16 (4.5–12)×109/L, platelets 247 (150–450)×109/L, C-reactive protein (CRP) 31.8 (<5) mg/L, blood urea nitrogen (BUN) 126 (13–43) mg/dL, creatinine 0.98 (0.53–0.79) mg/dL, albumin 25 (35–52) g/dL, complement factor C3 0.7 (0.9–1.8) g/L, complement factor C4 0.1 (0.1–0.4) g/L, tri-iodothyronine 6.5 (2.5–5.2) pg/mL, free thyroxine 2.4 (1–1.7) ng/dL, thyroid stimulating hormone (TSH) <0.02 (0.5–4.3) mU/L. Urinalysis showed nephrotic range proteinuria. Renal function deteriorated necessitating hemodialysis (HD). A renal biopsy revealed an immune complex-mediated membranoproliferative glomerulonephritis (MPGN). Elevated thyroid hormones and suppressed TSH levels with elevated thyroperoxidase antibodies and thyroid stimulating immunoglobulins confirmed the diagnosis of Graves’ disease. Corticosteroids were commenced and eventually thiamazole was added with gradual improvement of renal function, cessation of HD and discharge from the hospital.

Conclusions
Graves’ disease complicated by MPGN is extremely rare, but can cause life-threatening complications.
Rational exponential solutions of conformable space-time fractional equal-width equations
Authors: Zafar Asim 
Published: September 2018

AbstractIn this paper, the rational exponential solutions of two space-time fractional equal-width (FEW) equations are explored in the conformable derivative sense. The way to reach explicit exact solutions is to transform the fractional order PDEs into a nonlinear ODEs of discrete order through some properties of conformable derivatives and a fractional complex transforms. The subsequent equations have been elucidated by employing theexpafunction approach. Some new exact solutions of the said equations are effectively formulated and graphically conveyed with the aid of symbolic computation in Mathematica and MATLAB respectively.
A biosemiotic reading of Michel Onfray’sCosmos: Rethinking the essence of communication from an ecocentric and scientific perspective
Authors: Moser Keith 
Published: September 2018

AbstractInCosmos, Onfray argues in favor of a (re-) conceptualization of communication based on recent scientific discoveries. Similar to many researchers in the field of biosemiotics, the controversial philosopher posits that all life forms engage in constant semiosis. As opposed to being a singular characteristic that only homo sapiens possess, Onfray contends that all organisms are endowed with semiosic faculties that enable them to exchange information in purposeful and meaningful ways. Appealing to scientific logic, the philosopher debunks the common misconception that non-human vocalizations are merely the product of an internal machinery. Onfray offers concrete examples from both the animal and plant kingdom illustrating the astounding complexity of non-human semiosis. Nonetheless, in his reflections about the advent of hyperreality, the philosopher nuances his philosophical position by underscoring what makes the human primary modelling device of “language” the most sophisticated form of semiosis that exists in the biosphere. Although all material beings communicate with each other effectively in order to survive, to relate to each other, and to reproduce, Onfray recognizes that humans appear to have a heightened predisposition for symbolic exchange. The philosopher affirms that the human Umwelt is the richest and most complex semiotic space of all. Due to the pervasive nature of human semiosis in the modern world that threatens the ability of other life forms to create, stockpile, emit, and interpret signs, the philosopher also insists that preserving the fragile semiosic diversity of the “soundscape” is the key to averting the impending, anthropogenic eco-apocalypse.
Gesetzesevaluation und Wirkungsforschung im Sozialrecht: Eine problemorientierte Betrachtung aus den Niederungen von Auftragsforschung und Wirkungsanalyse im Bereich der Arbeitsmarktpolitik
Authors: Lenhart-Roth Karin , Wagner Alexandra 
Published: September 2018

Zusammenfassung
Die Autorinnen diskutieren Anforderungen und Praxis der retrospektiven Gesetzfolgenabschätzung am Beispiel der arbeitsmarktpolitischen Wirkungsforschung in Deutschland nach Umsetzung der Arbeitsmarktreformen Anfang der 2000er Jahre (sogenannte Hartz-Gesetze). Sie bieten mit ihrem Beitrag keine umfassende wissenschaftliche Analyse dieser Wirkungsforschung, sondern stellen vielmehr vor dem Hintergrund eigener Beteiligung an mehreren Evaluationsprojekten kritische Fragen zur Auftragsforschung, die sich im Spannungsfeld zwischen der Dienstleistungserbringung für einen Akteur mit selektiven politischen Verwertungsinteressen einerseits und den Anforderungen an kritische Wissenschaft andererseits bewegt. Die Autorinnen beschreiben dieses Dilemma und entwickeln Vorschläge, wie die arbeitsmarktpolitische Wirkungsforschung durch Transparenz und Demokratisierung sowie die stärkere Einbeziehung der verantwortlich handelnden Akteure und der Betroffenen verbessert werden kann. Insbesondere sollte die Wirkungsforschung durch einen transparenten Diskurs über die Widersprüche und Interessensgegensätze begleitet werden.

Abstract
Irradiation embrittlement testing of reactor pressure vessel (RPV) steel is essential to the surveillance experiment of nuclear power plant safety and requires high precision, high reliability, high repeatability, and high stability (4-High). It is very difficult to achieve the 4-High requirements of the remote control automatic impact test device in the hot cell. This article introduces our original designs of the obverse straight transfer specimen: the direct centering of the specimen notch and solid bath furnace. Aside from the common motor and automatic release pendulum device of automatic impact testing, the original new techniques of the automatic impact test consist of only two actuators (the push specimen plate and the notch automatic centering device). This innovative technique has successfully guaranteed the 4-High test results; it has simplified the track, reduced the number of steps, minimized the number of actuators of the automatic impact test, shortened transfer specimen time, and improved the precision of temperature control and notch centering. Through the successful use of this original technique, we have replaced the usual lateral transfer specimen and indirect centering of specimen notch with the obverse straight transfer specimen and direct centering of specimen notch. By adopting only one actuator, our technique has easily resolved the difficulties of terminal rebound and the disturbance and dislocation of the specimen. The operation has combined specimen transfer and centering into one step, which has smoothly overcome the difficult problems of instant specimen transfer, notch centering, and compression so that the specimen touches the test anvil closely. In sum, these innovative techniques have streamlined the complicated and rapid process of automatic impact testing into a simple and easy process.

Published: September 2018

Abstract
To study intergranular corrosion (IGC) characteristics, two cast grades of duplex stainless steels, 5A and 5A stabilized with niobium, were produced in a vacuum induction melting furnace. The samples were tested under three different heat-treatment conditions that were selected using a property diagram generated through the TCFE8 database of the Thermo-Calc® software (Thermo-Calc Software, Solna, Sweden). A Feritscope FMP30® (Fischer Technology, Inc., Windsor, CT) was used to measure the ferrite phase content in the samples and compared with that specified in the property diagram. Metallurgical characteristics were analyzed through optical microscopy, scanning electron microscopy, energy dispersive spectroscopy, and X-ray diffractometry. Each heat-treated sample possessed a distinct texture due to the formation of various intermetallic phases in the alloy. The corrosion behavior of the samples was studied using an oxalic acid etch test. Double-loop electrochemical potentiokinetic reactivation and sulfuric acid tests were conducted on the niobium-stabilized samples, and the results demonstrated that the samples possess superior resistance to corrosion compared to those not stabilized with niobium. The addition of niobium produced a mixture of niobium compounds that suppressed the chromium depletion and reduced the degree of sensitization. This study demonstrated the potential of using niobium as a stabilizer in the duplex stainless steel alloy to considerably reduce IGC.

Published: September 2018

Abstract
Permanent magnet synchronous motors (PMSM) are used commonly in numerous industrial applications, for instance, in mechatronics, vacuum pumps, energy storage flywheels, automotive, centrifugal compressors, and robotics. Nowadays, the sensorless speed control of PMSM is getting more attention, and several studies are progressing because of its low cost and reliable features. Normally, the speed control methods in PMSM are achieved with the help of sensors for position or speed estimation and control. But, these sensors are easily prone to breakage. Also, the flexibility towards parameter variations is poor in the conventional speed control methods. So, a sensorless T-source inverter-based PMSM drive that integrates the Proportional Integral (PI) controller with an adaptive mechanism to cope with the time-varying system parameters is proposed in this article. A sensorless module, namely, a model reference adaptive system (MRAS), is employed to estimate the rotor position of PMSM based on its performance characteristics Simulation results are illustrated to investigate the performance of the proposed method with different speeds under no load and loaded conditions. Moreover, the proposed approach not only minimizes the cost and size of the motor but also maximizes the reliability and accuracy.

Published: September 2018

Objectives: This study aims to analyze the nosocomial infection factors in post–cardiac surgery extracorporeal membrane oxygenation (ECMO) supportive treatment (pCS-ECMO).
Methods: The clinical data of the pCS-ECMO patients who obtained nosocomial infections (NI) were collected and analyzed retrospectively. Among the 74 pCS-ECMO patients, 30 occurred with NI, accounting for 40.5%; a total of 38 pathogens were isolated, including 22 strains of Gram-negative bacteria (57.9%), 15 strains of Gram-positive bacteria (39.5%), and 1 fungus (2.6%).
Results: Multidrug-resistant strains were highly concentrated, among which Acinetobacter baumannii and various coagulase-negative staphylococci were the main types; NI was related to mechanical ventilation time, intensive care unit (ICU) residence, ECMO duration, and total hospital stay, and the differences were statistically significant (P < .05). The binary logistic regression analysis indicated that ECMO duration was a potential independent risk factor (OR = 0.992, P = .045, 95.0% CI = 0.984-1.000).
Conclusions: There existed significant correlations between the secondary infections of pCS-ECMO and mechanical ventilation time, ICU residence, ECMO duration, and total hospital stay; therefore, hospitals should prepare appropriate preventive measures to reduce the incidence of ECMO secondary infections.

A Review of:
McKeever, C., Bates, J., & Reilly, J. (2017). School library staff perspectives on teacher information literacy and collaboration. Journal of Information Literacy, 11(2), 51-68. https://doi.org/10.11645/11.2.2187
Abstract
Objective – Researchers sought to determine school library staff perspectives on the information literacy knowledge held by secondary school teachers, and teacher relationships with the library.
Design – Interviews analyzed with thematic and axial coding.
Setting – Secondary schools in Northern Ireland.
Subjects – 21 schools across Northern Ireland were selected as a sample, including urban, rural, integrated, grammar, and secondary schools. 16 schools ultimately participated.
Methods – Semi-structured interviews were conducted with one library staff member at each selected secondary school. Interview audio and notes were transcribed and coded thematically both manually by the researchers and using NVivo. Categories were identified by open coding, then relationships identified via axial coding.
Main Results – The majority (10 of 16) of library staff members interviewed expressed that they had not been asked about information literacy by teachers, and only one library staff member described a truly collaborative instructional relationship with teaching staff. The majority of staff expressed either that teachers were familiar with concepts related to information literacy but did not know the name for them, or, that they thought information literacy was entirely unfamiliar to teachers at their school. Staff frequently cited competing priorities (for example, standardized testing) and limited class time as potential causes for teachers not focusing on information literacy concepts.
Conclusion – Both cultural and policy changes need to be made in schools to prioritize information literacy as a core competency for both students and teachers. The researchers call for greater intra-school collaboration as a means to achieve this cultural change.

Published: September 2018

Cocoa (Theobroma cacao L.) like most tropical trees is recalcitrant in tissue culture. Somatic embryogenesis is generally efficient micropropagation technique to multiply elite material. However, Somatic embryogenesis in cocoa is difficult and this species is considered as recalcitrant. One of the factors often considered as a component of in vitro recalsitrance is a high phenolic content and oxidation of these compounds. In cocoa tissue culture accumulate large amounts of poliphenolics compounds which probably impair further development. This study was conducted to investigate the composition of phenolic compounds in cocoa flower and leaves, and their changes troughout the somatic embryogenesis process. Calli were induced in cacao floral and leaves explants on a half-strenght Murashige and Skoog medium containing 30 g/L Glucose and combination of 2,4 dichlorophenoxyacetic acid (2,4 D) with kinetin (kin). Total polyphenol content was observed on Sulawesi 1 cocoa clone. Embryogenic and non-embryogenic callus were also compared. The percentage of callus production from flower tissue is 85%, percentage of embryogenic callus 40 %, although the percentage of somatic embryo production from embryogenic callus callus is 70%. The conservation of callus into somatic embryos followed by decline in phenol content and an increase in peroxidase. The synthesis kinetics for these compounds in calli, under different somatic embryogenesis conditions, revealed a higher concentration under non-embryogenic conditions. So that, phenolic compound can influence the production of calli and an absence the phenolic compound can enhance production of somatic embryo.Kata kunci: Theobroma cacao L., polifenol, embrio somatik, kalus, flavonoid, katekin, in vitro recalcitance
