Context. Nearby clusters of galaxies, z ≲ 0.1, are cosmic structures still under formation. Understanding the thermodynamic properties of merging clusters can provide crucial information on how they grow in the local universe.
Aims. A detailed study of the intra-cluster medium (ICM) properties of un-relaxed systems is essential to understand the fate of in-falling structures and, more generally, the virialization process.
Methods. We analyzed a mosaic of XMM-Newton observations (240 ks) of the Lyra system (z ∼ 0.067) that shows a complex dynamical state.
Results. We find the main cluster RXC J1825.3+3026 to be in a late merger phase, whereas its companion CIZA J1824.1+3029 is a relaxed cool-core cluster. We estimate a mass ratio of ∼1 : 2 for the pair. No diffuse X-ray emission is found in the region between them, indicating that these clusters are in a pre-merger phase. We found evidence of a galaxy group infalling on RXC J1825.3+3026 in an advanced state of disruption. The SG, one of the brightest galaxies in the Lyra complex, was very likely at the center of the infalling group. This galaxy has a gaseous “corona” indicating that it was able to retain some of its gas after the ram-pressure stripping of the intra-group medium. In this scenario the diffuse emission excess observed southwest of RXC J1825.3+3026 could be due to gas once belonging to the group and/or to cluster ICM dislocated by the passage of the group. Finally, we identified three high-velocity galaxies aligned between RXC J1825.3+3026 and the SG, two of these showing evidence of gas stripped from them during infall. We estimate them to be currently falling onto the main cluster at an infall velocity of ∼3000 km s−1.
Conclusions. Our study of the Lyra complex provides important clues about the processes presiding over the virialization of massive clusters in the local Universe.

Abstract
Background Fetal/neonatal alloimmune thrombocytopenia (FNAIT) results from maternal alloantibodies (abs) reacting with fetal platelets expressing paternal human platelet antigens (HPAs), mostly HPA-1a. Anti-HPA-1a abs, are the most frequent cause of severe thrombocytopenia and intracranial hemorrhage (ICH).
Objectives Titration of anti-HPA-1a in maternal serum using standard National Institute for Biological Standards and Control (NIBSC) 03/152 is one diagnostic approach to predict the severity of FNAIT. Recently, we found three anti-HPA-1a subtypes reacting with the β3 subunit independently or dependently from complexes with αIIb and αv. Endothelial cell-reactive anti-αvβ3 abs were found predominantly in cases with ICH. Our aim was to assess whether available standard material represents all anti-HPA-1a subtypes.
Materials and Methods In this study, anti-HPA-1a sera (NIBSC 03/152) and human monoclonal antibodies (moabs) against HPA-1a (moabs 26.4 and 813) were evaluated using transfected cell lines expressing αIIbβ3, αvβ3 or monomeric cβ3.
Results Flow cytometry analyses with well-characterized murine moabs recognizing αIIbβ3, αvβ3, or β3 alone demonstrated that AP3 reacts compound-independently, whereas compound-dependent moabs Gi5 and 23C6 reacted only with complexes. NIBSC 03/152, moabs 26.4, and 813 against HPA-1a reacted like AP3, same results were obtained with monomeric cβ3 in immunoblotting. Antigen capture assay targeting endothelial cells showed anti-HPA-1a reactivity disappearance after cβ3 beads adsorption. Furthermore, in contrast to anti-HPA-1a abs from ICH cases, none of NIBSC 03/152, 26.4, and 813 inhibited tube formation.
Conclusion These results suggest that current anti-HPA-1a standard material contains only the anti-β3 subtype. The absence of anti-αvβ3 makes NIBSC 03/152 less suitable as standard to predict the severity of FNAIT.
Visions of stagnation and maldistribution: monopoly capital, ‘white monopoly capital’ and new challenges to the South African Left
Authors: Aboobaker Adam 
Published: October 2019

SUMMARY
The term ‘white monopoly capital’ (WMC) has featured prominently in South Africa's recent popular economic discourse. Situating this rhetorical turn within discussion over the broader monopoly capital tradition, this piece argues for a need to move beyond the term considering problems with the idea that a concentrated market structure is driving stagnation and inequality in South Africa, but also because this conspiratorial language is harmful to South Africa’s political discourse.
Analysing logical meanings in Chinese: a discourse semantic perspective
Authors: Li Xueying 
Published: October 2019

ABSTRACT
Logical meaning, which is broadly concerned with relations between clauses, has long been of interest in linguistics. In particular, accounting for logical meanings in the language of Chinese is a continuing concern. The previous studies have taken a lexicogrammatical approach and described distinct features in terms of logical meaning in Chinese, which have caused difficulties in the analysis of logical meanings in Chinese. Against this background, this study departures from the stratum/level of lexicogrammar and sets out in the discourse semantics to introduce an alternative approach in Systemic Functional Linguistics (SFL) to analysing logical meanings in Chinese. This study will use as data from Chapter One of the Chinese novel Hong Lou Meng, and take an initial step in providing a relatively comprehensive account of logical meanings in Chinese according to the discourse semantic system of connexion. This description will explain how logical meanings in Chinese can be analysed through the dimensions of explicitness, type, and externality. It will also describe a distinct feature found to be relevant to the analysis through the three dimensions: indeterminacy of logical meanings in Chinese. It is hoped this approach can make some contributions to the field of discourse analysis so that analysts are equipped with useful linguistic tools in the discourse semantics when analysing logical meanings in Chinese.
The Feynman Path Integral to Characterize and Anticipate Bacteria Chemotaxis in a Host Healthy Body
Authors: Nieto-Chaupis Huber 
Published: October 2019

Abstract
In this paper the idea of Feynman’s path integral is introduced inside a nano biological system such as bacteria population where due to their property of chemotaxis, a stochastic modeling might be drawn to describe their mobility due essentially to electrical interactions among them as a recurrent resource to protect themselves against antibacterial agents such as macrophages. Due to composition of K+, Cl− and Na+ exists there a net charge along the internal and external phospholipid membrane of bacteria.
The model of path’s integration invented by Richard Feynman has been extensively used to tackle crucial problems in quantum mechanics for various decades essentially in atomic physics and nano physics. The idea of the path’s integral assumes a space-time pathway where the space­time bacteria displacements are governed by physics interactions that gives rise to changes of position in the space-time plane in a fully accordance to biological and physics laws. We worked out the idea of the Feynmans path integral to describe space-time dynamics of aggregations of bacteria trying to host a healthy body. We assumed that the bacteria interactions is governed by electric fields and potentials.
While the net charge is predominantly positive due to the high concentrations of Cl+, there are clearly external electric fields and potentials that might seriously affect the behavior of bacteria space-time dynamics. In this manner this phenomenology would fit the path integral theory. Therefore the change of the net charge in bacteria due to the presence of others charged nano organisms would affect their translational dynamics by being vulnerable to macrophages. Thus the knowledge of the pathway of these bacteria populations is seen as an advantage to tackle the beginning of diseases inside the framework of Internet of Bio-nano Things that targets to anticipate infections using electromagnetic pulses through advanced software-hardware interfaces. In order to assess possible advantages and disadvantages of this theory we use the Machine Learning algorithm.

Published: October 2019

Abstract
Zinc oxide nanoparticles (nano-ZnO) was used to modify carbon paste electrode (CPE) for a fast and sensitive electrochemical determination of gallic acid (GA). The study was carried out using cyclic voltammetry (CV and differential voltammetry (DPV) techniques, where the nano-ZnO-modified electrode exhibited an efficient and sensitive oxidation of GA. The cyclic voltammetric result showed a significant enhancement of the peak current from 250μA to about 410μA. The electrochemical behaviour of GA on the nano-ZnO modified carbon paste electrode was studied using DPV, showing a sensitivity of the electrode in a concentration range of 1 x 10−6 to 5.0 x 10−5 mol L−1, with a correlation coefficient R2 of 0.9968 and a limit of detection of 1.86 x 10−7 mol L−1 (S/N =3). The proposed electrode was used successfully for the determination of GA in red wine with recoveries of 103%.

Abstract
Big data in the coming days is going to become an integral part of life existing on this planet. Hence, introducing the early stage data analytics with the European Organization for Nuclear Research (CERN) and the National Center for Biotechnology Information (NCBI) would generate interest in the research community for the rapidly changing world of technology. This study is especially intended to integrate two organizations data for understanding the quantum realm computations. Generally, Quantum Computation (QC) creates the notion in the brain as Qu-bits. But here, QCs are the principles followed by the particles, atoms, molecules, and systems. Few of them are Pauli’s exclusion principle, superposition and entanglement. These principles played a vital role in the construction of proton to an atom and to higher systems. In this present work, we have collected homo-sapiens’ chromosomes data from NCBI and integrated it with CERN data to understand quantum computations. We have identified a couple of computations and communications taking place inside the genes by integrating the recent scientific results obtained at CERN. We have proposed a novel code-named peacock code (PCOC) and designed a prototype to develop a unique identity with blockchain technology. A typical correlation between CERN and NCBI datasets are integrated into this study statistically with R programming tool to understand supersymmetry and develop future computations with natural principles.

AbstractMacromolecules including macrocyclic species have been reported to have the potential to encapsulate biologically active compounds such as drugs through host-guest complexation to increase their solubility, stability and bioavailability. Here we investigate the complexation between nedaplatin, a second generation antineoplastic drug, andp-4-sulfocalix[4]arene, a macromolecule possessing a bipolar amphiphilic structure with good biocompatibility and relatively low haemolytic toxicity for potential use as a drug delivery system. Data from1H NMR, UV-Vis spectroscopy, Job’s plot analysis, HPLC, DSC and DFT calculations are detailed and suggest the formation of a 1:1 complex. The stability constant of the complex was experimentally estimated to be 3.6 × 104M−1and 2.1 × 104M−1which correspond to values of −6.2 and −5.9 kcal mol−1, respectively for the free energy of complexation while the interaction free energy is calculated to be −4.9 kcal mol−1. The formed species is shown to be stabilised in solution through hydrogen bonding between the host and the guest. The complex displayed enhanced antitumor activity against MDA-MB-231 cells compared to nedaplatin which may allow for its application in cancer therapy.

Published: October 2019

Abstract
This study presents a flow analysis on an atypical cylindrical cyclone separator with a large ratio of length to diameter. The Phase Doppler Particle Analyzer (PDPA) is used to measure the gas flow, and the numerical simulation is carried out by using the Reynolds Average Navier-Stokes (RANS) equation, the Reynolds stress model (RSM). Since the model is validated by good agreement between the numerical results and experimental data, and then the tangential velocity is analysed from the transient flow field and dynamic performance. The results showed that the tangential velocity of the transient flow field existed a non-axisymmetric phenomenon in the cross section, which was mainly presented as asymmetric distribution of the contours. The zero location of tangential velocity value was not coincided with the geometric center, where the tangential velocity was larger near the zero location. In addition, the dynamic character of tangential velocity was high-speed pulsating, with quasi-periodic characteristic. Meanwhile, a parameter of RMS was used to identify the degree of turbulence velocity deviating from mean velocity. The RMS data showed that the flow instability gradually increased with the fluid flowing into the cyclone separator from the inlet section, until reached a peak value at the position about 2.0 times the length to diameter. And then the flow instability gradually decreased, with the fluid energy dissipated.

Published: October 2019

Abstract
Low dielectric properties of BaTiO3/PVDF composites limit its application in modern microelectronics and high energy storage. In this work, three-phase composites with high dielectric properties were prepared based on the surface modification of BaTiO3(BT) ceramic. The results show that, after modification of BT, the dielectric constant of the BT/PVDF composite increased by 44%, and the dielectric loss decreased by 20% at 100Hz. Nickel powder was added to the modified composites for increasing dielectric constant, when the addition of nickel powder was 20%, the dielectric constant of composites was up to 441 and the dielectric loss of composite was only 0.057.

Published: October 2019

Abstract
The wear of heat-treated rolled carbon steels (HTRCSs) were performed under dry and wet sliding in DOT4 brake fluid is successfully investigated and reported in the study. The HTRCSs samples were obtained by heating to and soaking the as-rolled carbon steel (ARCS) at 950 °C prior to quenching or cooling in different media at different selected temperatures between (20 and 250 °C) and atmospheric conditions. The microstructures and wear track patterns of specimens were evaluated using SEM and high-resolution metallurgical microscope. The sliding wear behaviour and wear track patterns of the specimens impressed under 10N normal loads and reciprocating mode was used to assess the wear damages. The obtained wear properties were compared in air and DOT4 fluid environments using Anton Paar TRB tribometer. The results obtained showed that enhanced wear behaviours were obtained from the oil and water quenched samples as compared with the air and furnace cooled samples. The HTRCSs samples are more tolerable than as-rolled sample (ARCS) under dry sliding. However, beside the influences of the heat treatments, the lubricating effect of DOT4 is more pronounced in the results. The CoF ranges from 0.105 to 0.137 for wet sliding while higher CoF values (0.378-0.934) were obtained in the dry sliding.

Published: October 2019

Abstract
Hot-mixed asphalt (HMA) concrete has been extensively used in the concrete box-girder bridge deck pavement due to its excellent performance and driving comfort. Nevertheless, during HMA concrete construction, the high paving temperature may disturb the thermal field of the bridge, thereby causing the significant thermal response throughout the box girder. Therefore, this research aims to investigate the temperature behavior and thermal stress of a reinforced concrete box girder segment during HMA concrete paving. The transient thermal field theory and element deletion method were first adopted to establish a three-dimensional finite element model of a reinforced concrete box girder segment and simulate the dynamic paving process, respectively. Subsequently, the bridge monitoring data was used to validate the thermal field model and then the temperature distribution analysis was conducted. Finally, the thermal stress in the bridge was studied in cross-sectional area. Results demonstrate that the vertical temperature of the concrete box-girder during the paving process is declined with the increasing vertical distance to SFRC leveling layer, and its highest value occurs at 36min after starting to paving. Furthermore, in the vertical direction, the west web-plate is subjected to compressive stress at locations of two ends and tensile stress at locations of the middle. Meanwhile, the thermal stresses undergo a decline trend after short-term growth both in the box and flange slab in the transversal direction.

Authors: Tang P , Luo J C , Sun L , Li P Z 
Published: October 2019

Abstract
As the connection between the pressurizer and the main pipeline of nuclear reactor, thermal stratification occurs in the pressurizer surge line during the operation. The thermal stratification through the pipe wall increases the possibility of plastic deformation and fatigue failure in the nozzle, tee, elbow and weld. So it is of great significance to carry out research on the fracture mechanics of surge line under thermal stratification conditions. Therefore, in this paper, based on the results of finite element analysis and ASME specifications, and with the results of pipeline stress analysis under temperature and pressure transient loads, the fatigue crack growth analysis of the surge line under thermal stratification conditions is carried out, and the technical means of suppressing crack propagation is explored, which provides a reference for the safe operation of the surge line of the nuclear power plant.

Finite element study of tunable cantilever plate structure using position change
Authors: Chen L H , Chang L Q , Xue J T , Yang F H 
Published: October 2019

Abstract
In this paper, a tunable cantilever plate structure is presented, in which a box is attached to each corner of its free sides and a ball is placed in each box. Change of the balls position makes natural frequency of the structure variable, which expands working bandwidth of the structure to accommodate the complex ambient vibration. The modal analysis of the tunable cantilever plate is carried out by the finite element software-ABAQUS. Changing the balls position, it is found that there are maximum and minimum values in the natural frequency of the self-tuning structure, which forms a resonance bandwidth. Moreover, there are multiple position combinations of two balls at the same natural frequency in the range of resonance band. The paper studies the influence of mass and geometrical dimensions of boxes and balls on the natural frequency and bandwidth. While ensuring strength and stiffness of the structure, optimal material and size parameters are selected to improve the resonant bandwidth. This provides a theoretical basis for applying the tunable structure to piezoelectric energy harvester.

Abstract
This study was conducted to investigate the antimicrobial effect of Zingiber officinale var. officinale essential oil (EO), nisin, and their combination against some pathogenic and spoilage microorganisms. Minimum Inhibitory Concentration (MIC), Minimum Bactericidal Concentration (MBC), Minimum Fungicidal Concentration (MFC) and the synergism effect were assayed. The MIC values of nisin on Aspergillus niger; Eschericia coli and Pseudomonas fluorescens; Bacillus cereus; and Salmonella typhimurium and Staphylococcus aureus were 250; 500; 2000; and >2000 IU, respectively. On the other hand, MIC values of EO on E. coli; B. cereus and S. aureus; Pseudomonas fluorescens and A. niger; and Salmonella typhimurium were 0, 125; 0.25; 0.5; and 4%, respectively. 62.5 IU of nisin combined with 2% of EO could inhibit the growth of Salmonella typhimurium, S. aureus, and E. coli. In addition, the combination of nisin and EO had synergistic effect against B. cereus, A. niger, and Salmonella typhimurium. The combination of nisin and EO had no bactericidal effect against all five bacterias but it had fungicidal effect against A. niger at concentration 62.5 IU of nisin and 1% of EO. Sabinene (16.88%), Z-citral (11.25%), and camphene (10.05%) were the major components in Zingiber officinale var. officinale EO which contributed on its antimicrobial activity.
