Identifying the Potential for Climate Compatible Development Efforts and the Missing Links
Authors: Kalafatis Scott
Published: September 2017

Those examining climate compatible development and triple-win policy efforts that simultaneously negotiate sustainable development, climate change mitigation, and climate change adaptation considerations are on the cutting edge of exploring why and how policymakers address complex social problems that require balancing considerations about multiple, interrelated policy issues. Enhancing understanding of factors underlying the emergence of these efforts can help strengthen incentives for action, address implementation challenges, and anticipate inequities. This paper uses survey responses from 287 cities and logistic regression analyses to explore conditions and policy actions associated with potential climate compatible development efforts when economic development, sustainability, climate change mitigation, and climate change adaptation considerations overlap. It finds evidence that potential climate compatible development efforts were present in 10% of the cities studied. Adaptation was the issue most likely to act as the missing link when each of these other issues influenced city policy actions, and mitigation was the least likely. Contextual factors associated with these efforts included budget stress, leadership from a policy entrepreneur, higher college degree attainment rates, having an environmental department or commission, and the area of the city composed of water versus land. Examining factors associated with these issues acting as missing links revealed contradictions that highlight the necessity of further exploration of processes affecting the pursuit of climate compatible development.
Core Elements for Organizational Sustainability in Global Markets: Korean Public Relations Practitioners’ Perceptions of Their Job Roles
Authors: Jeong JiYeon , Park Nohil
Published: September 2017

For the purpose of enhancing organizational sustainability in global markets, organizational public relations practitioners in international firms take roles to respond toward the global public. This study explores practitioners’ perceptions of their job roles in global public relations firms and identifies the elements that support those roles. To address these concerns, a qualitative method, specifically an in-depth interview, was conducted because it endeavors to reveal and understand what lies deep within the complexity of a little-known phenomenon. As the specific public of this research, Korean practitioners were selected, since the public relations industry in Korea has been influenced by globalization, and diverse global public relations firms have branches in Korea. Analysis of in-depth interviews suggests a typology of three newly defined roles for Korean practitioners: strategic counselor/manager role, non-strategic technician role, and business manager role for practitioners’ own firms. It also identifies nine elements affecting public relations practitioners’ roles. The important and powerful elements were chiefly attributed to culturally specific influences. This study provides critical clues for enhancing both entrepreneurial sustainability in global markets and the professionalism of public relations. Finally, public relations practitioners will be better able to make optimal decisions regarding their client organizations’ adopted strategy.

Worldwide Occurrence and Investigations of Contamination of Herbal Medicines by Tropane Alkaloids
Authors: Chan Thomas
Published: September 2017

Tropane alkaloids occur mainly in Solanaceae plants. In the present review, the main objective is to describe the worldwide occurrence and investigations of anticholinergic poisoning due to the contamination of herbal teas and herbs by tropane alkaloids. Tropane alkaloid poisoning can occur after consumption of any medicinal plant if Solanaceae plants or plant parts are present as contaminants. Globally, almost all reports in 1978–2014 involve herbal teas and one of the prescribed herbs in composite formulae. Contamination most likely occurs during harvest or processing. As for prescribed herbs, on-site inspection is necessary to exclude cross-contamination and accidental mix-up at the retail level. The diagnosis is confirmed by screening for the presence of Solanaceae species and tropane alkaloids. Herbal teas and herbs contaminated by tropane alkaloids can pose a serious health hazard because these relatively heat-stable alkaloids may exist in large quantities. The WHO repeatedly emphasises the importance of good agricultural and collection practices for medicinal plants. DNA barcoding is increasingly used to exclude the presence of contaminants (particularly toxic species) and product substitution. All suspected cases should be reported to health authorities so that investigations along the supply chain and early intervention measures to protect the public can be initiated.

Published: September 2017

Hepatocellular carcinoma (HCC) is a worldwide health threat with increasing incidence and a high mortality rate. Most HCC patients are diagnosed at an advanced stage and are unable to undergo potential curative surgery. Transcatheter arterial chemoembolization (TACE) and transcatheter arterial chemotherapy infusion (TACI) are two of the main palliative treatments for advanced HCC patients. The clinical efficacy and safety of TACE and TACI are controversial. For this reason, we conducted a systematic review and meta-analysis to summarize the current evidence. We searched for randomized controlled trials (RCTs) and cohort studies that compared the clinical outcomes and adverse effects in HCC patients who received TACE or TACI treatments. The database search was performed and last updated on November 1, 2016. Overall survival and clinical response were compared using a hazard ratio (HR) with a 95% confidence interval (CI). A total of 11 clinical studies that included 13,090 patients were included based on the inclusion/exclusion criteria, of which 9 were cohort studies and 2 were RCTs. TACE was associated with a 23% lower hazard of death compared to TACI (pooled HR = 0.77, 95% CI = 0.67‐0.88,p = 0.0002). Patients receiving TACE had a 28% higher disease control rate (DCR) and 162% higher objective response rate (ORR). Only the increase in ORR associated with TACE was statistically significant [DCR: odds ratio (OR) = 1.28, 95% CI = 0.35‐4.64,p = 0.71; ORR: OR = 2.62, 95% CI = 1.33‐5.15,p = 0.002]. TACE is associated with more favorable survival and response rate than TACI in patients with intermediate or advanced HCC.
Growth and characterization of textured well-faceted ZnO on planar Si(100), planar Si(111), and textured Si(100) substrates for solar cell applications

Published: September 2017

In this work, textured, well-faceted ZnO materials grown on planar Si(100), planar Si(111), and textured Si(100) substrates by low-pressure chemical vapor deposition (LPCVD) were analyzed by X-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), and cathode luminescence (CL) measurements. The results show that ZnO grown on planar Si(100), planar Si(111), and textured Si(100) substrates favor the growth of ZnO(110) ridge-like, ZnO(002) pyramid-like, and ZnO(101) pyramidal-tip structures, respectively. This could be attributed to the constraints of the lattice mismatch between the ZnO and Si unit cells. The average grain size of ZnO on the planar Si(100) substrate is slightly larger than that on the planar Si(111) substrate, while both of them are much larger than that on the textured Si(100) substrate. The average grain sizes (about 10–50 nm) of the ZnO grown on the different silicon substrates decreases with the increase of their strains. These results are shown to strongly correlate with the results from the SEM, AFM, and CL as well. The reflectance spectra of these three samples show that the antireflection function provided by theses samples mostly results from the nanometer-scaled texture of the ZnO films, while the micrometer-scaled texture of the Si substrate has a limited contribution. The results of this work provide important information for optimized growth of textured and well-faceted ZnO grown on wafer-based silicon solar cells and can be utilized for efficiency enhancement and optimization of device materials and structures, such as heterojunction with intrinsic thin layer (HIT) solar cells.

Published: September 2017

We present [Fe/H] and [Ca/Fe] of ∼600 red giant branch (RGB) members of the globular cluster Omega Centauri (

). We collect medium-resolution (

) spectra using the Blanco 4 m telescope at the Cerro Tololo Inter-American Observatory equipped with Hydra, the fiber-fed multi-object spectrograph. We demonstrate that blending of stellar light in optical fibers severely limits the accuracy of spectroscopic parameters in the crowded central region of the cluster. When photometric temperatures are taken in the spectroscopic analysis, our kinematically selected cluster members, excluding those that are strongly affected by flux from neighboring stars, include relatively fewer stars at intermediate metallicity (

) than seen in the previous high-resolution survey for brighter giants in Johnson & Pilachowski. As opposed to the trend of increasing [Ca/Fe] with [Fe/H] found by those authors, our [Ca/Fe] estimates, based on Ca ii H & K measurements, show essentially the same mean [Ca/Fe] for most of the metal-poor and metal-intermediate populations in this cluster, suggesting that mass- or metallicity-dependent SN II yields may not be necessary in their proposed chemical evolution scenario. Metal-rich cluster members in our sample show a large spread in [Ca/Fe], and do not exhibit a clear bimodal distribution in [Ca/Fe]. We also do not find convincing evidence for a radial metallicity gradient among RGB stars in

Published: September 2017

As a step toward completing and characterizing the census of the solar neighborhood, we present astrometric, photometric, and spectroscopic observations of 32 systems observed with the Cerro Tololo Inter-American Observatory 0.9 m and 1.5 m telescopes. Astrometry from the 0.9 m indicates that among the 17 systems that had no previous published trigonometric parallaxes, 14 are within 25 pc. In the full sample, nine systems have proper motions larger than 0.″5 yr−1, including 2MASS J02511490-0352459, which exceeds 2.″0 yr−1. VRI photometry from the 0.9 m and optical spectra from the 1.5 m indicate that the targets have V = 11–22 mag and spectral types M3.0V–L3.0V. For 2MASS J23062928-0502285 (TRAPPIST-1), we present updated astrometry and photometric variability based on over 12 years of observations. Of the nine binaries in the sample, two promise mass determinations in the next decade: LHS 6167AB, an M4.5V system for which we present an accurate parallax placing the binary at 9.7 pc, and 2MASS J23515048-2537367AB, an M8.5V system at 21.1 pc for which we present the first evidence of an unseen, low-mass companion. Most importantly, Na i and K i gravity indicators, Hα measurements, long-term photometric variability, locations on the H-R diagram, and kinematic assessments indicate that as many as 13 of the systems are young, including candidate members of young moving groups, with ages less than ∼120 Myr.
Sparse Reconstruction of the Merging A520 Cluster System
Authors: Peel Austin , Lanusse François , Starck Jean-Luc
Published: September 2017

Merging galaxy clusters present a unique opportunity to study the properties of dark matter in an astrophysical context. These are rare and extreme cosmic events in which the bulk of the baryonic matter becomes displaced from the dark matter halos of the colliding subclusters. Since all mass bends light, weak gravitational lensing is a primary tool to study the total mass distribution in such systems. Combined with X-ray and optical analyses, mass maps of cluster mergers reconstructed from weak-lensing observations have been used to constrain the self-interaction cross-section of dark matter. The dynamically complex Abell 520 (A520) cluster is an exceptional case, even among merging systems: multi-wavelength observations have revealed a surprising high mass-to-light concentration of dark mass, the interpretation of which is difficult under the standard assumption of effectively collisionless dark matter. We revisit A520 using a new sparsity-based mass-mapping algorithm to independently assess the presence of the puzzling dark core. We obtain high-resolution mass reconstructions from two separate galaxy shape catalogs derived from Hubble Space Telescope observations of the system. Our mass maps agree well overall with the results of previous studies, but we find important differences. In particular, although we are able to identify the dark core at a certain level in both data sets, it is at much lower significance than has been reported before using the same data. As we cannot confirm the detection in our analysis, we do not consider A520 as posing a significant challenge to the collisionless dark matter scenario.
Preheating of the Intergalactic Medium by Gravitational Collapse and Ultraviolet Background
Authors: Zhu Weishan , Feng Long-Long
Published: September 2017

The preheating of the intergalactic medium by structure collapse and ultraviolet background (UVB) is investigated in cosmological hydrodynamical simulations. When gravitational collapse is the sole heating mechanism, we find that (1) 60% and 45% of the IGM are heated up to S > 8 and 17 keV cm2, respectively, at z = 0, but the fractions drop rapidly to a few percent at z = 2; (2) the entropy of the circumhalo gas

is higher than the virial entropy for more than 75% of the halos with masses

since z = 2, but the fraction higher than the entropy,

, required in the preventive model of galaxy formation is only 15%–20% for halos with

at z = 0, and decreases as redshift increases; (3) assuming a metallicity of

, the fraction of halos whose circumhalo gas has a cooling time longer than the Hubble time

is merely 5%–10% at

, and even less at

for halos with

; and (4) gas in the filaments undergoes the strongest preheating. Furthermore, we show that the UVB cannot enhance the fraction of the IGM with

, but can increase the fraction of low-mass halos (

) having

to ∼70% at z = 0 and that having

to 15%–30% at

. Our results indicate that preheating due to gravitational collapse and UVB is inadequate to fulfill the needs of the preventative model, especially for halos with

Objective.

To evaluate the rate of somatic NLRP3 mosaicism in an Italian cohort of mutation-negative patients with cryopyrin-associated periodic syndrome (CAPS).

Methods.

The study enrolled 14 patients with a clinical phenotype consistent with CAPS in whom Sanger sequencing of the NLRP3 gene yielded negative results. Patients’ DNA were subjected to amplicon-based NLRP3 deep sequencing.

Results.

Low-level somatic NLRP3 mosaicism has been detected in 4 patients, 3 affected with chronic infantile neurological cutaneous and articular syndrome and 1 with Muckle-Wells syndrome. Identified nucleotide substitutions encode for 4 different amino acid exchanges, with 2 of them being novel (p.Y563C and p.G564S). In vitro functional studies confirmed the deleterious behavior of the 4 somatic NLRP3 mutations. Among the different neurological manifestations detected, 1 patient displayed mild loss of white matter volume on brain magnetic resonance imaging.

Conclusion.

The allele frequency of somatic NLRP3 mutations occurs generally under 15%, considered the threshold of detectability using the Sanger method of DNA sequencing. Consequently, routine genetic diagnostic of CAPS should be currently performed by next-generation techniques ensuring high coverage to identify also low-level mosaicism, whose actual frequency is yet unknown and probably underestimated.

Une nouvelle temporalité dans l’action sociale et médico--sociale
Authors: Jaeger Marcel
Published: September 2017

La référence de plus en plus fréquente à la notion de parcours tend à l’emporter sur la priorité donnée jusqu’à présent à la notion de projet. Elle correspond à une nouvelle façon de penser l’intervention auprès des personnes en difficulté du fait de la maladie, du handicap, de l’âge, des difficultés sociales et économiques. En effet, il ne s’agit plus seulement d’envisager l’avenir des personnes en définissant, avec ou sans elles, ce qui est censé répondre le mieux à leur intérêt, mais de tenir compte de la réalité et de la complexité de leur parcours de vie, pour mieux les accompagner, y compris dans leurs échecs et dans leurs fluctuations.

Initier une logique de parcours vers l’inclusion sociale des personnes handicapées psychiques à partir d’un foyer de vie
Authors: Simeray Isabelle
Published: September 2017

Les personnes confrontées aux manifestations psychiques chroniques sont partagées entre maladie et handicap par une réalité historique : le développement parallèle des deux mondes bien distincts de la psychiatrie et de l’action sociale, relevant de la division de notre système de protection sociale. Pourtant, chronique, variable, invisible et imprévisible, la maladie place la personne en situation de handicap social, la situant aux frontières juridiques des secteurs sanitaire et médico--social et la maintenant éloignée de la société. La création, en 2014, du premier foyer de vie accueillant exclusivement des personnes en situation de handicap psychique, dans les Alpes-de-Haute-Provence, invite les acteurs de ces deux secteurs à collaborer. Dépasser la notion sectorielle d’alternative à l’hospitalisation conduit à proposer des formes souples d’accueil qui considèrent la variabilité des troubles psychiques, dépendants de l’environnement, du traitement médical et de la relation à l’autre.

En partant de deux novateurs – Deligny et Freinet – qui furent de grands pédagogues, il est possible de réfléchir sur deux concepts : parcours et projet. Dans leur démarche, c’est la demande de la personne qui est essentielle car on ne peut concevoir de projet si l’on ne cultive pas la découverte. Aboutir à un projet, c’est organiser les éléments de sa découverte pour en faire une création nouvelle. Et la découverte et la création demandent du temps, ce que l’administration n’est guère disposée à accorder. C’est le moment de revenir à l’essentiel : faire en sorte que le parcours conduise au projet, puisque l’inverse produit bien souvent des malentendus.

Dans un monde où les technologies numériques se démocratisent, apparaissent également des œuvres immersives déployées sur de multiples supports : les transmédias de fiction.Ces œuvres transmédias semblent amener une transformation de l'usage du médium dans la création artistique. En effet, traditionnellement, chacun décide de ce que sera la concrétisation d'une idée en œuvre par rapport à ce qu'il sait faire, à l'expérience de création qu'il a acquise dans le passé, et à son médium de prédilection. Lorsqu'un peintre crée, il verra probablement mentalement avant même d'attraper un pinceau, les pigments qu'il souhaite utiliser, le grain de la toile ou l'onctuosité de ses couleurs. Dans un élan d'anticipation de sa création, il transformera le matériel en médium.Mais que voit un artiste qui est sensibilisé à la musique, aux interfaces numériques, à la peinture, aux jeux et à la vidéo ? Quel matériel choisirait cet auteur qui n'a pas d'habitude de création attachée à un médium en particulier ? Ne pourrait-il pas voir une œuvre hybride concrétisée via différents vecteurs de création, en d'autres mots, un transmédia ? Ainsi, il existerait des auteurs capables de créer sans que leur création ne soit limitée par un médium de prédilection ; des auteurs transmédias possédant une véritable palette de médium, assemblés pour porter une même œuvre.
The Effects of Digitalization on Professional and Amateur Astronomy Considered Through the Categories of Identity and Attachment
Authors: Tchalakov Ivan , Popravko Irina
Published: September 2017

Applying the notion of identity, the article analyses the role of real time observation of professional and amateur astronomers in the context of ongoing digitalization of research. Unveiling the importance of materiality and immediate relationships with instruments, we took a critical stance to the established research approaches to this subject, in particular the ethnography of profession and the actor-network theory (ANT). Bearing on of Julian Orr studies of professional culture and our own ANT notion of ‘heterogeneous coupling', an attempt was made to introduce a new language for analysing the two knowledge communities, based on the sociology of taste and attachment of Antoine Hennion and sociology of regimes of worth of Luck Boltanski, which allows to grasp both similarities and differences in the astronomers' identities.

Development of a 3D Tunneling Current Probing System for Micro- and Nano-Coordinate Metrology
Authors: Sun Zhong Yuan , Schuler Alexander , Hausotte Tino
Published: September 2017

The demands for precision measurement of three dimensional micro-and nanogeometries over a large area have rapidly increased during the last few years. To meet such requirements, many different nanometre resolving 3D capable probing sensors and corresponding 3D positioning systems to operate the sensors for 3D measurements have been developed. The mechanical contact-free, electrical work piece probing based on the scanning tunneling microscopy principle offers new possibilities for 3D micro coordinate measurements as well as for nanometre resolved topography measurements in micro-and nanometrology. This paper introduces an updated version of this probing sensor system extended with a 3D movable piezo scanner to directly detect its probing direction. With the magnitude and the direction of the contact vector forwarded to the position control of the nanopositioning and nanomeasuring machine NMM-1 all of the 3D measurement commands of NMM-1 can be utilized, allowing 3D surface scans and especially 3D free-form surface scans.
Self-Calibration of Coupling Error for 3-DOF Displacement Measurement of Planar Working Stage Based on Two Planar Gratings
Authors: Liu Yong Meng , Li Ze Lin , Du De Hao , Yuan Mao Qiang , Huang Jing Zhi , Tan Jiu Bin
Published: September 2017

A self-calibration method of coupling error is presented for 3-DOF displacement measurement of a planar moving stage based on two planar gratings. The self-calibration method using Fourier series is developed to extract the periodic systematic errors from the coupling errors. The extracted periodic systematic errors are compensated. Experiments are conducted to validate the validity of the self-calibration method and experimental results indicate that the coupling errors in x and y directions are reduced by 2 and 1.5 times respectively. It can be therefore concluded that the self-calibration method is suitable for the 3-DOF displacement measurement of a planar moving stage to improve the positioning accuracy.

This paper presents a high-resolution real-time 3D coordinate measurement system based on multi-angle intersection and cylindrical imaging. The measuring angle is detected by the linear camera equipped with cylindrical lenses, whose field of view is a 3D space rather than 2D plane. This camera has prominent advantages in precise coordinate measurement and dynamic position tracking due to the high resolution and outstanding frame rate of linear CCD. Each camera is a 1D angle measuring unit which confirms an angle thereby a plane passing through the light spot. With three cameras arrangement in front of the measurement field, the 3D coordinate of the light spot can be reconstructed by multi-angle intersection. An accurate and generic calibration method is introduced to calibrate this camera. The proposed calibration method is based on nonparametric ideas to find the mapping from incoming scene rays to photo-sensitive elements, and this method (black box calibration) is still effective even if the lens distortion is high and asymmetric. It is applicable to a central (single viewpoint) camera equipped with any lenses. The proposed calibration method is applied to the 3D coordinate measurement system. The coordinate measurement accuracy of the designed system is better than 0.49mm.

Authors: Meier Nicolas , Georgiadis Anthimos
Published: September 2017

In this work, a method for measuring the radial clearance of bearings mounted on a shaft before and after assembling in an automatically and standardized way will be described. A setup was constructed, which enables to measure the radial clearance of different types of bearings with different dimensions. Tests with roller and ball bearings with tapered bore and adapter sleeves show that the developed system provides as good or better results than the manual test method. The results are reliable, objective, independent from the user and reproducible. Based on the results, the process of assembling could be readjusted. By using a closed loop method, it will be achieved that bearings will be mounted on a shaft with the specified radial clearance which is defined by the manufacturer of the bearing.

Published: September 2017

The measurement capability of the dimensional X-ray Computed Tomography (DXCT) is studied by a computer simulation and the result was compared to the observed data obtained by the measurement of calibrated gauges of same shape that consist of simple geometric forms. The simulation showed that the measurement using polychromatic x-ray is different from that of monochromatic x-ray, but the difference was far smaller than expected from the results of observed data. These results indicated that the deviation of the measured values of geometric objects was not caused by simple origin and more causes have to be taken into consideration for the actual apparatus.

Published: September 2017

The visual measurement technology is prerequisite to implement high accuracy pose measurement tasks for space manipulator. Firstly, a Newton Downhill-Least Square (ND-LS) algorithm is presented to optimize the object’s pose in this paper. Secondly, the pose measurement error caused by the focal ratio, the principal point, image coordinates and world coordinates is analyzed separately. Finally, the performance of suggested algorithm and the results of pose error analysis are evaluated respectively by re-projection error (RPE) and mean absolute of pose error (MAPE). Experimental results validate that the ND-LS algorithm is superior than Newton method or Least Square (LS) method in pose optimization. In general, solved by ND-LS algorithm, the RPE reduces nearly 3 times contrasted to initial value, and it also reduces to half of that obtained by both Newton method and LS method. On the other hand, the results of pose error analysis indicates that the error influenced by the principal point approximately equals to the one caused by image coordinates, about 2 and 15 times higher than what caused by both focal ratio and world coordinates, respectively, to orientation error with MAPE. Moreover, the relationships above are about 2 and 20 times separately as for the position error.

Authors: Lin Jia Rui , Ren Yu , Guo Yin , Ren Yong Jie , Yang Ling Hui , Zhu Ji Gui
Published: September 2017

Large-scale coordinate measurement frequently involves unifying coordinate frames of individual measurement systems by aligning two sets of common reference points, which is called coordinate transformation. During this transformation process, some uncertainty is introduced into the final measurement results from common points. This paper studies the relationship between this introduced uncertainty and common points in order to minimize it. First, an uncertainty estimation model of coordinate transformation is developed to quantify the introduced uncertainty. Then the relationship between the introduced uncertainty and the arrangement of the common points is simulationally and experimentally investigated and some feasible and efficient arrangements are proposed in view of minimizing it.

Published: September 2017

Electrostatic-discharge (ESD) immunity measurements of different layout manners in the drain-side of HV pLDMOS devices are investigated in this paper. Here, eleven kinds of drain-side "npnpn" arranged-types of pLDMOS-SCR parasitic structure are used to evaluate the layout impacts on ESD robustness. In this study, at first the layout type of N+ region is continuous extended into the drain-side P+ cathode. Secondly, the layout type of N+ region is modulated by some discrete-distributed areas in the drain-side. From the experimental results, we can find that the ESD capability of the continuous extended and discrete distributed in the drain-side can be promoted, where all of the secondary breakdown current (It2) values can be achieved 7 A. However, the discrete-distributed layout type has higher breakdown voltage (VBK) than that of the reference group (the pure none modulated pLDMOS-SCR npnpn-type structure). Therefore, the discrete-distributed layout types show good electrical properties and reliability immunities.

The paper reports electro-contact welding on Hardox 450 steel with С-V-Cr-Nb-W flux-cored wire. Supplementary irradiation by intense pulsed electron beam was carried out to improve mechanical properties. Micro-and nanohardness, Young modulus and tribological parameters of the modified surface were tested mechanically. It is pointed at the significant increase in the friction coefficient because the surface layer fractures and particles of the surfaced layer are involved in the process of friction. Using the methods of optical and scanning microscopy a great number of micro-pores were detected both on the irradiated surface and through the surfaced layer modified by intense pulsed electron beam. It is demonstrated that electron-beam processing of the deposited layer surface is the reason for occurrence of multi-layer structure. According to measurements it was determined that the modified (surface and transition) layers are 0.3 to 0.5 μm on overage. It was also found out that irradiation of the surfaced metal leads to significant refining of structural elements because of ultrahigh speeds of crystallization and further cooling down of the modified layer. The phase composition of the surfaced metal modified by pulsed electron beam is explored. Niobium carbide (NbC) is reported to form in the surface layer.

Experimental research has been carried out to determine quantitative content of solid and gas component of welding aerosol in mechanized gas-shielded welding with constant and pulsewise electrode wire supply. As a result, it has been established that the pulsewise electrode wire supply reduces the release of harmful components of welding aerosol (welding dust СО and SiO2) by 20-25% thanks to lower energy characteristics (the transfer frequency of electrode metal droplets and the time of their exposure to critical temperatures at a short-circuit).
