Reflections on Parallel Lines in Sociology and Linguistics
Authors: Lu Deping 
Published: May 2019

AbstractThere are two lines of development in both sociological and linguistic thought. One makes a sharp distinction between individuals and society, with an overwhelming emphasis on the role and function of society’s norms and rules. The second holds a more integrative perspective on the interaction of society and its members and sees social norms as immanent in individual conduct rather than as externally imposed on the practices of everyday life. The first developmental line reaches its highest point in Saussure’s linguistic theory, while the second one is best promoted in Erving Goffman’s dramaturgy theory. A thorough analysis of these two lines with reference to sociology and linguistics, respectively, helps further an understanding of the nature of sign. This article attempts to highlight a significant turn of semiotic thinking in Goffman’s sociological theory that has to a large extent been neglected. This semiotic turn could be formulated as characterizing the sign in terms of its more interactional function in the practices of everyday life and away from its more structural and external function of providing norms and rules for such interactions. In this approach the function of the sign is made more coherent with the social dimensions of individuals in the interactional situations of everyday life.
Knowing Is Belonging: Recognitional Deixis and Emergence of Common Ground in Religious Conversion
Authors: Khachaturyan Maria 
Published: May 2019

AbstractThis article explores the situated usage of recognitional deixis, a prominent feature of the religious register of the Catholic community of Mano, Guinea. Recognitional deixis is understood to be the marking of referents as known and recognizable by the interlocutors, typically belonging to their common ground. While deictic markers are known to reflect a specific speaker-hearer-object configuration, I suggest reversing the indexical relationship and claim that instead of indexing contextual relationships (context presupposition), deictic markers rather project them in a performative fashion (context creation). In the study in question dealing with the marking of common ground by recognitional deixis, what gets projected is a presupposition of shared knowledge. Because of the dialogic orientation of recognitional deixis, as a consequence of presupposition projection, the speaker and the addressees emerge as knowledge-sharing co-insiders. This, in turn, contributes to a performative creation of a community of co-insiders—a religious community sharing religious knowledge.
The “Tiny Hand” of Donald Trump and the Metapragmatics of Typographic Parody
Authors: Donzelli Aurora , Bugden Alexandra Powell 
Published: May 2019

AbstractSince his rise to the political stage in 2015, Donald Trump’s heterodox style of self-presentation has stirred heated metapragmatic debates within the American and international public: Was that “locker-room talk,” or abusive speech? Is his verbal irreverence an unacceptable defiance of fundamental principles of interactional ethics, or a brave attempt at reforming contemporary American speech by dismissing the epistemic inaccuracy and moral hypocrisy of political correctness? This article engages these debates by analyzing an ingenious form of typographic parody that recently appeared on digital social media. Modeled on Trump’s handwriting, the font “Tiny Hand” operates on multiple metapragmatic levels. First, the font’s childlike shapes establish an iconic connection between Trump’s hand(writing) and his brain, which, incapable of adult reasoning, generates dangerously infantile political decisions. Second, as a replica of Trump’s handwriting, the font parodies the president’s habit of correcting journalists with handwritten marginalia, thus speaking back to his attempts at silencing the press. Third, Tiny Hand works as a counter-meta-parody of the president’s political incorrectness. Finally, by evoking the parodies of Trump’s allegedly diminutive hands (and implicitly small penis) that circulated during the electoral race, the font operates as an inside joke addressed at and indexical of Trump’s counterpublic.

Abstract
The potential-driving model is used to describe the driving potential distribution and to calculate the pre-neutron emission mass distributions for different incident energies in the

reaction. The potential-driving model is implemented in Geant4 and used to calculate the fission-fragment yield distributions, kinetic energy distributions, fission neutron spectrum and the total nubar for the

reaction. Compared with the built-in G4ParaFissionModel, the calculated results from the potential-driving model are in better agreement with the experimental data and evaluated data. Given the good agreement with the experimental data, the potential-driving model in Geant4 can describe well the neutron-induced fission of actinide nuclei, which is very important for the study of neutron transmutation physics and the design of a transmutation system.

Published: May 2019

Abstract
Significant enhancements of

production at very low transverse momenta were recently observed by the ALICE and STAR collaborations in peripheral hadronic A+A collisions. The anomalous excess points to coherent photon-nucleus interactions in violent hadronic heavy-ion collisions, which were conventionally studied only in ultra-peripheral collisions. Assuming that the coherent photoproduction is the underlying mechanism responsible for the excess observed in peripheral A+A collisions, its contribution in p+p collisions with nuclear overlap, i.e. non-single-diffractive collisions, is of particular interest. In this paper, we perform a calculation of exclusive

photoproduction in non-single-diffractive p+p collisions at the RHIC and LHC energies based on the pQCD motivated parametrization using the world-wide experimental data, which could be further employed to improve the precision of the phenomenological calculations for photoproduction in A+A collisions. The differential rapidity and transverse momentum distributions of

from photoproduction are presented. In comparison with the

production from hadronic interactions, we find that the contribution of photoproduction is negligible.

Abstract
The multinucleon transfer reaction in the collisions of 40Ca+ 124Sn at

MeV is investigated using the improved quantum molecular dynamics model. The measured angular distributions and isotopic distributions of the products are reproduced reasonably well by the calculations. The multinucleon transfer reactions of 40Ca + 112Sn, 58Ni + 112Sn, 106Cd + 112Sn, and 48Ca + 112Sn are also studied. This demonstrates that the combinations of neutron-deficient projectile and target are advantageous for the production of exotic neutron-deficient nuclei near N, Z = 50. The charged particles' emission plays an important role at small impact parameters in the de-excitation processes of the system. The production cross sections of the exotic neutron-deficient nuclei in multinucleon transfer reactions are much larger than those measured in the fragmentation and fusion-evaporation reactions. Several new neutron-deficient nuclei can be produced in the 106Cd + 112Sn reaction. The corresponding production cross sections for the new neutron-deficient nuclei, 101, 112Sb, 103Te, and 106, 107I, are 2.0 nb, 4.1 nb, 6.5 nb, 0.4

Authors: Andreozzi Assunta , Brunese Luca , Iasiello Marcello , Tucci Claudio , Peter Vanoli Giuseppe 
Published: May 2019

Abstract
The investigation of bioheat transfer is a difficult issue because it entails a mixture of many mechanisms to take into account, such as thermal conduction in tissues, convection and blood perfusion, metabolic heat generation, vascular structure, changing of tissue properties depending on physiological condition and so on. This topic has a key role to predict accurately the temperature distribution in tissues, especially during biomedical applications. In this paper, different bioheat transfer models are resumed and compared. The biological tissue is modelled as a porous sphere and liver tissue properties are used. Governing equations are averaged over a Representative Elementary Volume (REV) of the living tissue. Transient bioheat equations based on models like, for example, Pennes model, Local Thermal Non-Equilibrium equations (LTNE model), are employed. In the employed equations, radiative heat transfer is also considered. Governing equations with the appropriate boundary conditions are solved with the finite-element code COMSOL Multiphysics®. The effects of hyperthermia on the living tissue are included with a source term in the tissue energy equation. Results are presented in terms of temperature profiles in the biological tissue; the aim is to appreciate differences due to the various bioheat models.

Published: May 2019

Abstract
During the last decades the CFD computer modelling of fire has increased significantly. The CFD fire simulator has been purposely developed and optimized for fire protection; nowadays they have a high reliability and ample perspectives of further development. The main drawbacks of CFD fire simulators are mainly due to the complexity of its setting. They are not user friendly and require a good competence on fires and fair competence in computing. To be able to estimate how the simulation outcome is influenced by model assumptions and simplifications, the user has to evaluate the dominating physical processes and involved empirical parameter that has an essential influence on the specific fire scenario. In this paper the Thermo-gravimetric (TGA) and Cone-calorimetric tests will be used to show in which ranges the input parameters such as reference temperature (i.e. the temperature of the released mass rate peak), thermal conductivity, pyrolysis range, specific heat, in a fire simulation with the “Fire Dynamics Simulator”, will vary based on the measurement errors, measurement uncertainty, or misinterpretation of the user. Fire simulation validated on experimental tests are used to evaluate the impact of those variant input data on the simulation. A parametric analysis has been carried out and the results are evaluated and discussed.
Experimental validation of numerical model for evaluation of local heat transfer coefficient in coiled tubes
Authors: Vocale P , Abbenante M , Bozzoli F. , Rainieri S , Pagliarini G 
Published: May 2019

Abstract
The efficiency of the enhanced heat transfer equipment was widely investigated in literature by adopting both experimental and numerical approaches. Obviously, the numerical tools allow improving the knowledge of the fundamental heat transfer mechanisms in curved geometries, since they enable to evaluate punctually the velocity and temperature distributions. On the other hand, it has to be pointed out that the numerical results can be considered reliable only if they are validated throughout the comparison with either analytical results or experimental data. The validation of numerical models is usually carried out by considering average heat transfer performances, therefore this approach does not guarantee that these models enable to evaluate the local heat transfer phenomena with the same accuracy. In the present paper a promising numerical tool for evaluating local convective heat transfer in coiled-tubes, within the laminar regime, is presented. The Navier-Stokes and energy equations are solved by means of the open-source CFD software OpenFOAM®, with second-order accurate finite-volume schemes, within the framework of the SIMPLE algorithm. The robustness of the numerical model is assessed by comparing the numerical outcomes to the local experimental data available in literature.
Simplified numerical modelling of infrared radiation effects in tomato dry peeling
Authors: Cuccurullo G , Giordano L 
Published: May 2019

Abstract
In view of the increasing interest in developing sustainable systems for tomato peeling, the unsteady thermal field in a rotating tomato exposed to an array of infrared emitters was studied. First, a predictive 3D numerical model was developed to simulate heat transfer in a rotating tomato undergoing infrared heating. Since simulations required great computational efforts, it was considered appropriate to introduce a simplified model. To this purpose, the net radiative heat flux on the tomato surface was approximated by a suitable periodic function: the related angular velocity accounted for tomato rotation, while its amplitude was linked up with view factors between the tomato and the heating source. On such basis, a 1D axisymmetric model involving radiative heating from the source regarded as a periodic II-type boundary condition was set up. It was found that temperatures predicted by the simplified model agreed well with the 3D model output. Finally, a parametric analysis was performed to investigate the effect of the position and angular velocity of the tomato samples on the rate and uniformity of IR heating. Results were pursued both by the 3D and 1D model, in the latter case obtaining faster yet accurate responses.
Low-order dynamic model of a domestic electric oven Part I: Experimental characterization of the main heating functions
Authors: Lucchi Michael , Lorenzini Marco , Di Paola Vincenzo 
Published: May 2019

Abstract
Household electric ovens can be considered as one of the most common domestic appliances and they usually represent a low-efficiency category, whose value ranges between 10% and 12%. Usually, oven energy class is determined by means of a test procedure regulated by the EN 60350-1 European standard, which moreover requires a proper control of the oven centre temperature. However, during normal operating conditions, because of the presence of the food at the centre, the temperature control within the cavity occurs on the basis of the temperature measured by a probe usually placed in the proximity of one of the cavity corners. Any analysis aimed at decreasing energy consumption must therefore be able to model in sufficient detail the thermal behaviour of the appliance, while still retaining a degree of simplicity. Lumped parameter models have proved themselves a suitable choice, but, especially for gray-box and black-box types, their parameters need to be estimated and validated through experiments. In this work, a common household oven (Electrolux) was instrumented in order to investigate the temperature distribution within the appliance as a consequence of the operating conditions adopted, with the subsequent aim to model the dynamic behaviour of the oven.
The oven was set into a cabinet normally used during the energy consumption test, in order to capture the proper thermal dynamics of the system, and the two main heating functions (forced and natural convection) were also investigated in the range 160-240
[openbullet]C. In addition to the temperature measured by the probe (a Pt500 sensor), several thermocouples were placed within the cavity in order to measure the oven centre temperature and to obtain the mean temperatures of walls and heating elements, while one thermocouple of the same type monitored the temperature of the surrounding environment. The number of thermocouples was chosen by trial and error on the basis of modelling needs. Also, four power meters were used to record the electric power consumption of each heating element and the overall electric power absorbed. Since the ultimate goal of this research activity is to create a dynamic model of the oven for control design purposes, the experimental data obtained in the campaign have subsequently been used for this purpose.

Published: May 2019

Abstract
The recent regulations about fluorinated greenhouse gases introduce a rapid phase-down of traditional, environmentally harmful refrigerants. Consequently, new working fluids are continuously appearing on the market, leading to the need of testing them to analyse their performance before making an ultimate choice. In the present paper, a test rig built to carry out experimental studies on different refrigerant in a drop-in application is described and first results for the set-up commissioning are commented. The experimental campaign was carried out in typical water-to-water heat pump operating conditions, varying the cold water temperature at evaporator inlet from 10 °C to 20 °C, with a step of 2.5 °C, and hot water temperature at condenser inlet from 30 °C to 50 °C, with a step of 10 °C and the compressor shaft rotational frequency from 30 Hz to 80 Hz, with a step of 10 Hz. The first findings demonstrate that the experimental results of some key performance parameters, namely heating capacity, COP and compressor volumetric efficiency, agree well with open literature trends, allowing to state that the experimental facility was correctly designed and can be used to deep the analysis on performance assessment of new refrigerants in a drop-in application.
Comparison of two hygroscopic materials for a solar-assisted desiccant-based air handling unit
Authors: Roselli C , Sasso M , Tariello F 
Published: May 2019

Abstract
Solar-driven air-conditioning systems are an interesting solution to reduce greenhouse gas emissions as they are essentially powered with a renewable energy source. Among the solar heating and cooling systems, desiccant-based air handling units (AHUs) are a very promising alternative as they require low temperature thermal energy for operation in cooling mode. In this paper the experimental plant of University of Sannio (Benevento, Southern Italy), consisting of an AHU with a desiccant wheel using as hygroscopic material silica gel is coupled with solar thermal collectors. This AHU has been also simulated with a different material for the desiccant wheel, the MIL101@GO-6 (MILGO). It is a composite material, consisting of graphite oxide dispersed in the MIL101 metal organic framework network structure, that shows a better dehumidification effectiveness. The energy and environmental performance of a desiccant-based solar heating and cooling system with this new material have been evaluated with respect to the conventional AHU based on cooling dehumidification. Yearly based dynamic simulations of the plant serving a university classroom located in Benevento have been performed. Furthermore, a comparison with the air-conditioning system equipped the currently adopted material (silica gel) has been carried out too. The optimal plant configuration varying collector type (flat plate and evacuated tube), tilt angle and surface has been found.

Numerical simulation of a turbulent Lead Bismuth Eutectic flow inside a 19 pin nuclear reactor bundle with a four logarithmic parameter turbulence model
Authors: Chierici Andrea , Chirco Leonardo , Da Vià Roberto , Manservisi Sandro 
Published: May 2019

Abstract
Computational Fluid Dynamic allows scientists and engineers to investigate fluid flow in complex geometries and evaluate heat transfer between a solid body and a fluid. In the present paper we study the heat transfer of a Lead Bismuth Eutectic (LBE) turbulent flow in a bare 19 pin nuclear reactor bundle. When dealing with low Prandtl number fluids, like LBE for which Pr = 0.025, proper turbulence models are needed to improve the prediction of heat transfer. We use here a four logarithmic parameter turbulence model in order to calculate Reynolds stresses and turbulent heat flux. In particular, an equation for temperature fluctuations and one for their dissipation are solved. These variables are used to model thermal characteristic time scales. The results are reported for different values of the Peclet number and a fixed value of the pitch to diameter ratio. The obtained values of the Nusselt number are compared with experimental correlations, that can be found in literature, and with the ones obtained using a Simple Eddy Diffusivity model, where the eddy thermal diffusivity is calculated as proportional to eddy viscosity through a modeled turbulent Prandtl number.
