Abstract
In the present work, the scientists were successful in obtaining a friction surfaced coating of mild steel over mild steel, mild steel over stainless steel (AISI 304) and stainless steel over stainless steel using a low-cost conventional milling machine. A 22 factorial method with three replications was used to design the experiments. The influence of variation in rotational speed (1400 rpm and 1000 rpm) and table feed rate (4.17 mm/s and 2.67 mm/s) on coating width, thickness and interface temperature of the coating and substrate was investigated. Multi-response optimization was performed and the developed model was validated by confirmatory experiments. The results showed that, with an increase in rotational speed and table feed rate, width and thickness of the coating decreases, while temperature increases. An infrared (IR) camera provided thermographs that elaborated the distinct stages of heat dissipation during the process of coating formation. The bond integrity and strength of the coating was analyzed by bend tests and Vickers micro hardness test. The results revealed that a higher hardness value was obtained at the interface of the coating as compared to coating and interface.
Chemical composition of chosen phase constituents in austempered ductile cast iron
Authors: Warmuzek Małgorzata , Polkowska Adelajda 
Published: July 2018

Abstract
A procedure a for multi-step characterization of microstructural features observed in austempered ductile cast iron (ADI), was proposed based on the results of microscopic examinations, a local X-ray microanalysis and EBSD-based crystallographic evaluation. The polyphase complex microregions having an increased content of alloying elements such as Mo, Cr, Mn in comparison with that estimated for the alloy's matrix, were observed in the examined material. As a first step, a classification of microregions was performed based on their morphology and specific distribution in the alloy's microstructure. Subsequently, by using established criteria for the selection of microanalysis data for a further microregions discrimination, several groups of particles characterized by a particular ratio of the alloying elements, were distinguished. The particles were classified based on the specific range of the carbide stabilizers concentration revealed, then were ascribed in situ to two types of carbides identified by means of EBSD analysis. Furthermore, the effect of heat treatment conditions on the evolution of the chemical composition of the microregions was examined experimentally and discussed.
Investigation of initial yielding in the small punch creep test
Authors: Çakan Betül Gülçimen , Durmuş Ali 
Published: July 2018

Abstract
Unlike the uniaxial creep test results, the interpretation of small punch (SP) test results is not straightforward due to the complex deformation behavior of SP specimens. Accordingly, the reliability of correlations of SP creep test results with corresponding uniaxial tests is still not clear. One crucial point is that the initial yielding at the beginning of an SP creep test results in the hardening of the material before creep sets in and is thought to affect the creep properties. In this study, to clarify this effect, first an accurate numerical model of the SP creep test has been developed following which this model was used to study the influence of test parameters such as specimen thickness, punch diameter and the radius of the receiving hole on the initial yielding. Varying these parameters changes the deformation mechanisms and thus has a strong effect on the deflection-time curves along with the amount of initial plastic deformation. It was observed that decreasing specimen thickness and the punch diameter increased the initial yielding. Conversely, increasing the radius of the receiving hole resulted in higher initial yielding.
Thermography using a 1D laser array – From planar to structured heating
Authors: Ziegler Mathias , Thiel Erik , Studemund Taarna 
Published: July 2018

Abstract
In the field of optically excited thermography, flash lamps (impulse-shaped planar heating) and halogen lamps (modulated planar heating) have become established for the specific regimes of impulse and lock-in thermography. Flying-spot laser thermography is implemented by means of a rasterized focused laser, e. g. for crack detection (continuous wave operation) and photothermal material characterization (high-frequency modulated). The availability of novel technologies, i. e. fast and high-resolution IR cameras, brilliant innovative light sources and high-performance data acquisition and processing technology will enable a paradigm shift from stand-alone photothermal and thermographic techniques to uniform quantitative measurement and testing technology that is faster and more precise. Similar to an LED array, but with irradiance two orders of magnitude higher, a new type of brilliant laser source, i. e. the VCSEL array (vertical-cavity surface-emitting laser), is now available. This novel optical energy source eliminates the strong limitation to the temporal dynamics of established light sources and at the same time is spectrally clearly separated from the detection wavelength. It combines the fast temporal behavior of a diode laser with the high optical irradiance and the wide illumination area of flash lamps. In addition, heating can also be carried out in a structured manner, because individual areas of the VCSEL array can be controlled independently of each other. This new degree of freedom enables the development of completely new thermographic NDT methods.

Abstract
This study focuses on the fabrication of aluminum alloy 8011 with 8 % fly ash (FA) composite (AA8011-8 % FA), using the stir casting method. The dry sliding wear characteristics of the composite were investigated at various sliding parameters. A three-level central composite design experiment was developed using response surface methodology with various parameters such as load, time, and sliding velocity and varied in the range of 5 to 15 N, 5 to 15 min, and 1.5 to 4.5 m × s−1, respectively. Dry sliding wear tests were performed as per the experimental design using a pin-on disc at room temperature. The regression result obtained indicated that the developed model performed well in relating the wear process parameters and predicted the wear behavior of the composite. The surface plot showed that the wear rate increases with increase in load, time, and sliding velocity. Moreover, the surface morphology of the worn-out composite was examined using a scanning electron microscope.

Published: July 2018

Abstract
Microstructural evolution and compressive properties of an extruded Mg-2Dy-0.5Zn (at.%) alloy sheet at 350°C were investigated. As the compressive strain increased, the volume fraction of dynamic recrystallization increased, the fine lamellar 14H long period stacking ordered phase precipitated in the dynamic recrystallization grain, and the Mg12ZnDy phase with an 18R long period stacking ordered structure gradually bent. These secondary phases not only acted as nucleation sites to promote dynamic recrystallization but also restrained grain growth by inhibiting dislocation movement and grain boundary sliding. The compressive yield strength, ultimate compressive strength, and compressive strain of the alloy sheet were 161 MPa, 212 MPa, and 12.4% at 350°C, respectively. The high compressive strengths were mainly attributed to grain refinement, kink band strengthening of the 18R long period stacking ordered phase and precipitation strengthening of the fine lamellar 14H long period stacking ordered phase in the dynamic recrystallization grain.

Published: July 2018

Abstract
The influence of minor Nd substitution on the microstructure and corrosion resistance of Mg–Zn–Y alloy were investigated. Results indicate that the partial substitution of Nd for Y can effectively refine grains but deteriorate the corrosion resistance of extruded Mg–Zn–Y alloy. The corrosion rates, measured by immersion tests in 3.5% NaCl solution at 25°C, are 12 and 19 mm · y−1 for the Mg-5.6Zn-1.4Y and Mg-5.6Zn-1.0Y-0.4Nd alloys, respectively. The negative effect of Nd is associated with enhanced microgalvanic corrosion resulting from grain refinement and higher area of second phase, as well as to a degraded protectiveness of the corrosion product layer.

The current state of the development of bioenergy in Ukraine is presented. Prospects for the production of heat from biomass by sectors of consumption until 2050 are estimated. The most important barriers to the development of the sector are analyzed, ways for their complete or partial overcoming are suggested.
The current state of the development of bioenergy in Ukraine is presented. It is shown that according to Ukraine’s energy balance for 2010-2016, the average annual growth of bioenergy is 45 % by the «production of biofuel and wastes» and 35 % by the «total primary energy supply from biofuels and wastes». Despite quite good dynamics of the development, to reach key figures of the National Renewable Energy Action Plan until 2020 it is necessary to speed up bioenergy growth. Prospects for the production of heat from biomass by sectors of consumption until 2050 are estimated. The obtained results show that the share of renewables in the total heat production may be over 57 % in 2050. At that the consumption of renewable energy sources will be about 13.8 Mtoe/yr (of which biomass accounts for over 90 %), and the respective replacement of natural gas will come to about 17 billion m3/yr. The most important barriers to the development of bioenergy sector are analyzed, and ways for their complete or partial overcoming are suggested. Ukraine has quite good legal basis for the development of renewable energy. In particular, it includes the feed-in tariff for power produced from alternative energy sources and stimulating tariff for heat produced from alternative energy sources for households and public buildings. For the wider involvement of biomass in the fuel and energy balance of Ukraine it is necessary to provide legal basis and implementation of a number of important measures.Among others, they include creating preconditions for increasing harvesting of wood in Ukraine’s forests, introduction of the electronic biofuel trade system, ensuring fair access of independentproducersofbiomassheattoheatnetworksandother.

The Dispersion and Rotation Measure of Supernova Remnants and Magnetized Stellar Winds: Application to Fast Radio Bursts
Authors: Piro Anthony L. , Gaensler B. M. 
Published: July 2018

Abstract
Recent studies of fast radio bursts (FRBs) have led to many theories associating them with young neutron stars. If this is the case, then the presence of supernova ejecta and stellar winds provides a changing dispersion measure (DM) and rotation measure (RM) that can potentially be probes of the environments of FRB progenitors. Here we summarize the scalings for the DM and RM in the cases of a constant density ambient medium and of a progenitor stellar wind. Since the amount of ionized material is controlled by the dynamics of the reverse shock, we find that the DM changes more slowly than in previous simpler work, which assumed a constant ionization fraction. Furthermore, the DM can be constant or even increasing as the supernova remnant sweeps up material, arguing that a young neutron star hypothesis for FRBs is not ruled out if the DM is not decreasing over repeated bursts. The combined DM and RM measurements for the repeating FRB 121102 are consistent with supernova ejecta with an age of ∼102–103 years expanding into a high density (∼100 cm−3) interstellar medium. This naturally explains its relatively constant DM over many years as well. Other FRBs with much lower RMs may indicate that they are especially young supernovae in wind environments or that their DMs are largely from the intergalactic medium. We therefore caution about inferring magnetic fields simply by dividing an RM by DM, because these quantities could originate from distinct regions along the path an FRB propagates.
Galactic Archeology with the AEGIS Survey: The Evolution of Carbon and Iron in the Galactic Halo

Published: July 2018

Abstract
Understanding the evolution of carbon and iron in the Milky Way’s halo is of importance because these two elements play crucial roles in constraining star formation, Galactic assembly, and chemical evolution in the early universe. Here we explore the spatial distributions of the carbonicity, [C/Fe], and metallicity, [Fe/H], of the halo system based on medium-resolution (R ∼ 1300) spectroscopy of ∼58,000 stars in the southern hemisphere from the AAOmega Evolution of Galactic Structure (AEGIS) survey. The AEGIS carbonicity map exhibits a positive gradient with distance, as similarly found for the Sloan Digital Sky Survey carbonicity map of Lee et al. The metallicity map confirms that [Fe/H] decreases with distance from the inner halo to the outer halo. We also explore the formation and chemical evolution history of the halo by considering the populations of carbon-enhanced metal-poor (CEMP) stars present in the AEGIS sample. The cumulative and differential frequency of CEMP-no stars (as classified by their characteristically lower levels of absolute carbon abundance, A(C) ≤ 7.1, for subgiants and giants) increases with decreasing metallicity and is substantially higher than previous determinations for CEMP stars as a whole. In contrast, that of CEMP-s stars (with higher A(C)) remains almost flat, at a value of ∼10% in the range −4.0 ≲ [Fe/H] ≲ −2.0. The distinctly different behaviors of the CEMP-no and CEMP-s stars relieve the tension with population synthesis models assuming a binary mass-transfer origin, which previously struggled to account for the higher reported frequencies of CEMP stars, taken as a whole, at low metallicity.
Black Hole Formation in Fallback Supernova and the Spins of LIGO Sources
Authors: Schrøder Sophie L. , Batta Aldo , Ramirez-Ruiz Enrico 
Published: July 2018

Abstract
Here we investigate within the context of field binary progenitors how the the spin of the Laser Interferometer Gravitational Wave Observatory (LIGO) sources vary when the helium star-descendant black hole (BH) is formed in a failed supernova (SN) explosion rather than by direct collapse. To this end, we make use of 3d hydrodynamical simulations of fallback supernova in close binary systems with properties designed to emulate LIGO sources. By systematically varying the explosion energy and the binary properties, we are able to explore the effects that the companion has on redistributing the angular momentum of the system. We find that, unlike the mass, the spin of the newly formed BH varies only slightly with the currently theoretically unconstrained energy of the SN and is primarily determined by the initial binary separation. In contrast, variations in the initial binary separation yield sizable changes on the resultant effective spin of the system. This implies that the formation pathways of LIGO sources leading to a particular effective spin might be far less restrictive than the standard direct collapse scenario suggests.
B Cell Defects Observed in Nod2 Knockout Mice Are a Consequence of a Dock2 Mutation Frequently Found in Inbred Strains

Published: July 2018

Abstract
Phenotypic differences among substrains of laboratory mice due to spontaneous mutations or pre-existing genetic variation confound the interpretation of targeted mutagenesis experiments and contribute to challenges with reproducibility across institutions. Notably, C57BL/6 Hsd mice and gene-targeted mice that have been backcrossed to this substrain have been reported to harbor a duplication in exons 28 and 29 of Dock2. In this study, we demonstrate the presence of this Dock2 variant in the widely used Nod2−/− mice. Nucleotide-binding oligomerization domain-containing protein 2 (NOD2) is a cytosolic innate immune receptor associated with inflammatory bowel disease susceptibility. Consistent with a role of NOD2 in an immunological disorder, Nod2−/− mice bred at our institution displayed multiple B cell defects including deficiencies in recirculating B cells, marginal zone B cells, and B1a cells in vivo, as well as defects in class switch recombination in vitro. However, we found that these effects are due to the Dock2 variant and are independent of Nod2 deletion. Despite originating from the same gene-targeted founder mice, Nod2−/− mice from another source did not harbor the Dock2 variant or B cell defects. Finally, we show that Dock2−/− mice display the same B cell defects as mice harboring the Dock2 variant, confirming that the variant is a loss-of-function mutation and is sufficient to explain the alterations to the B cell compartment observed in Nod2−/− mice. Our findings highlight the effects of confounding mutations from widely used inbred strains on gene-targeted mice and reveal new functions of DOCK2 in B cells.
