Background: The concept of banking sector development is multi-dimensional, and it is difficult to establish a single description for it because it is an interconnected process that encompasses increases in the number and quality of financial services.
Objectives: The objective of the study is to examine the impact of macroeconomic determinants on banking sector development in Nepal.
Methods: The study applied the vector error correction model (VECM) approach technique with economic time series data ranging from 1995 to 2020. The study employed the VECM model to avoid the spurious regression problem in the construction of contemporary time series econometrics. The co-integration analysis is used in the study to determine the long-run equilibrium relationship between the macroeconomic variable and the banking sector development of the model. Banking sector development is measured by the arithmetic average of the normalized values of banking depth, banking efficiency, and banking stability.
Result: This study reveals that per capita GDP and remittances have a positive and significant impact on the banking sector development. Similarly, government expenditure and stock market capitalization have positive and statistically significant roles to explain banking sector development in Nepal. In addition, it demonstrates that trade openness and inflation have a marginally negative but insignificant impact on banking sector development.
Conclusion: There is a long-term equilibrium relationship between macroeconomic variables and banking sector development. Macroeconomic policies and institutional quality play an important role in the banking sector development.
Implications: For policymakers since it clarifies the significance of sound macroeconomic policies in the development of the banking industry while taking into account the quality of the existing institutional infrastructure.

Authors: Zaari H. , Ouassoul K. , Mezzat F. , Elyahyaoui F. , El Kenz A. , Benyoussef A.
Published: January 2023

This paper aims to present a group of compounds Dy2M2O7 (with M = Hf, Ce and Zr) which could be an alternative having the same function as TiO2. Based on our studies and those reported in the literature, we will discuss in detail the roles and the functional mechanism of the catalysts. The results show that Zr2Dy2O7 is the best candidate to be a photo-catalyst: it has a band gap close to 2.2 eV, and a good absorption in visible range compared to the other compound having absorption in UV. The quantum efficiency of Zr2Dy2O7   reaches up to 3%, and the limit of conduction band and valence band are localized in potential redox zone. Doping with Cerium gives another energy level, which allows having other optical transitions and improving the absorption and reaching the quantum efficiency to 4% in a visible range.
Tradiciones peruanas, el tratamiento de la diégesis y su relación con los relatos populares
Authors: Huarag Álvarez Eduardo
Published: January 2023

En el presente ensayo empezamos por una necesaria información del contexto cultural en el que se difundieron las tradiciones. Luego, hacemos una breve exposición de la metodología que décadas atrás utilizara Vladimir Propp al analizar los relatos populares. Ciertamente, las Tradiciones peruanas de Ricardo Palma conservan ciertas estructuras funcionales del relato popular, pero el narrador aborda diversos modos de contar lo que revela su inagotable creatividad. Hemos escogido varias tradiciones para el análisis, unos más cercanos a la crónica histórica, y otros, más vinculados al relato ficcional maravilloso. Y aunque no dejamos de advertir los vínculos derelatos semejantes que se difundieron con anterioridad, lo concreto es que Palma marca la distinción con su estilo, su humor, y ese apego a las costumbres y creencias que se mantienen en la memoria de la cultura oral.
Cuando el “Príncipe de las tinieblas” asoma en las páginas de las Tradiciones de Palma
Authors: Adriazola Silva Juan Carlos
Published: January 2023

Desde tiempos inmemoriales en la cultura occidental la figura del demonio, diablo, Lucifer, Satanás, “Príncipe de las Tinieblas”… ha sido uno de los personajes centrales en la teología cristiano católica que ha servido para explicar el origen del mundo y la creación del hombre, la presencia del bien y del mal sobre la tierra, y porqué los seres vivientes pueden estar a veces en estado de gracia o de pecado. La literatura universal y la literatura peruana no han estado exentas de la presencia de este ser espiritual en las páginas deun sinnúmero de obras escritas. La influencia que el demonio ha ejercido sobre hombres y mujeres a lo largo de la historia, se ha hecho evidente mediante una serie de actitudes, comportamientos y características que los vinculan al actuar propio del Maligno. Las Tradiciones peruanas, no han estado ajenas a este personaje teológico, que, en la pluma de don Ricardo Palma, toma ribetes particulares, pues a veces encarna el mal en absoluto, en otros momentos puede convertirse en un ser humorístico o jocoso y, en no pocas veces, se le presenta como un ser burlado y castigado por la astucia del hombre. ¿El demonio es realmente un personaje recurrente de las Tradiciones peruanas? ¿Cómo caracteriza Palma a este personaje que habita en el inframundo y sale constantemente de sus dominios para tentar a hombres y mujeres por igual? Las respuestas a estas interrogantes y otras más son el objetivo del presente artículo.
Residual Stress Measurement of Cold Sprayed Metallic and Ceramic Coating During Spraying
Authors: Watanabe Yuta , Yamada Motohiro , Fukumoto Masahiro
Published: January 2023

Cold spraying is a promising process for fabricating functional coatings. Because of the solid-state particle deposition, the electrical and chemical properties of the coatings are similar to those of the bulk materials. Mechanical properties, on the other hand, differ from those of bulk materials due to severe plastic deformation of the particles. Residual stress may thus be an important variable to track during cold spraying although the formation mechanism is not entirely clear. In this study, the residual stress of metallic (copper) and ceramic (titania) coatings is measured during the cold spray process. The results are presented and discussed.
Control of Arc Motion in a dc Plasma Spray Torch with a Cascaded Anode
Authors: Zhukovskii Rodion , Chazelas Christophe , Vardelle Armelle , Rat Vincent
Published: January 2023

Two common concerns in dc plasma torches are stability of plasma jet and anode erosion. The challenge is how to get a stable plasma jet with minimal anode erosion. This study tackles this question by using an external axial magnetic field applied to a cascaded plasma torch. A 3D, time-dependent model of the torch is used to predict the value of the magnetic field and its effect on heat flux to the anode as well as plasma jet stability. The model couples the gas phase and electrodes, making it possible to follow anode temperature evolution. For specific operating conditions, the model predicts an azimuthal self-magnetic field induced by electric arcing and the subsequent effect of an external field on arc attachment and anode wall temperature. This approach is expected to provide a better understanding of arc behavior in dc plasma torches and facilitate the control of anode erosion.

Published: January 2023

In this study, different sets of plasma-sprayed YSZ thermal barrier coatings were deposited via Ar/H2 and N2/H2 plasmas and compared based on deposition efficiency (DE), thermal conductivity (TC), and furnace cycle testing (FCT). The top-performing coatings exhibited equivalent FCT lifetimes with TC values in the range of 1.15-1.25 W/mK at 1200 °C, but the deposition efficiency of those produced with N2/H2 plasma was twice as high, resulting in a 55% reduction in production costs.

Published: January 2023

A wide range of properties can be achieved in intermetallic coatings applied by gas detonation spraying (GDS). The properties of Fe-40at%Al GDS layers, however, may change when exposed to temperatures exceeding a threshold level. To characterize such changes, Fe-40at%Al GDS coatings were subjected to systematic dilatometric studies in which temperatures were cycled from room temperature to 1180 °C. The investigation revealed both irreversible and reversible phase transitions as described in the paper. Dilatometry measurements obtained from sintered samples made from the same powder are presented for comparison.

Published: January 2023

Cold spraying is a semi-empirical method in that spray parameters must be optimized experimentally in regard to coating quality and deposition efficiency. In this work, porosity and deposition efficiency are the key parameters in the optimization of corrosion-resistant zinc coatings produced by high-pressure cold spraying. The deposition process is described along with the tests used to assess the morphology, adhesion, and anticorrosion properties of the coatings obtained.

Published: January 2023

The objective of this study is to assess the wear resistance, hardness, and porosity of HVOF-sprayed Cr3C2-25NiCr coatings applied using different oxygen and C3H8 flow rates. In the experiments, six coating samples were prepared and subjected to various tests. The sample deposited with the highest oxygen flow rate and lowest fuel-oxygen ratio exhibited the lowest porosity and highest microhardness. In general, the higher the surface hardness, the better the erosion and cavitation wear resistance. The most intense wear occurred during the erosion test conducted with an impingement angle of 60°.

Published: January 2023

This study assesses the erosive wear performance of hard-phase-reinforced coatings developed for use on hammer drills employed in mining operations. Several laser-clad coatings consisting of a nickel matrix with various tungsten carbides were evaluated along with two Fe-based alloys, FeCrBSi and FeCrNiBSi, and a WC-CoCr reference layer deposited by HVOF spraying. Erosion tests were conducted in 15° steps up to an angle of 90° and coating performance was determined based on volume loss obtained by 3D profilometry. At low angles, the more brittle materials lost significantly less volume, but at 90°, wear-resistant steel performs almost as well as a hard-phase loaded coating. Laser-clad layers with spherical fused tungsten carbides (FTC) performed better overall than coatings with regular (angular) FTC.

Published: January 2023

This study investigates the microstructure and efficiency of coating-based heating elements produced by deposition of various powders, including aluminum oxide (Al2O3), alumina-titania (Al2O3-TiO2), nickel-chromium (NiCr), and copper, using flame spraying, suspension plasma spraying, high-velocity oxyfuel (HVOF) spraying, and cold spraying techniques. The main goals are to assess the dielectric strength of flame and plasma sprayed alumina, compare the electrical resistivity of HVOF and flame sprayed NiCr, and obtain coating cross-sectional images to shed light on the challenges and potential of different heating element designs. The Al2O3 layer produced by suspension plasma spraying appeared to be more reliable due to its cauliflower-like structure, corundum content, and hygroscopic properties. Resistivity was found to be higher in the flame sprayed NiCr than in the HVOF deposit mainly due to discontinuities and imperfections such as cracks, pores, and oxygen content. The micrographs taken from sample cross-sections show penetration of flame-sprayed NiCr into the flame-sprayed Al2O3 and Al2O3-TiO2 layers, which decreases the effective thickness of the dielectric. However, interlocking between NiCr and Al2O3-TiO2 coatings can be beneficial when cohesion is a concern.

Published: January 2023

This study investigates the effect of incorporating different reinforcing particles on the microstructure, electrical resistance, and heating efficiency of flame-sprayed nickel-based coatings. Feedstock powders were prepared by adding Al2O3, TiO2, and WC particles to NiCrAlY powder, and the various combinations were applied to alumina-coated carbon steel substrates. A number of Joule heating experiments were conducted by creating voltage differences across the coatings and measuring temperature changes due to induced electron flow and associated resistive heating. It was found that the electrical properties of the ceramic particles have a major effect on heat generation and that there is considerable room for improvement.

Published: January 2023

Single component tin coatings have been successfully cold-sprayed onto carbon fiber reinforced polymers. Coatings with mixed metal powders have also been sprayed to improve conductivity for lightning strike protection purposes. Test results indicate a noticeable improvement in deposition efficiency with the addition of a secondary metallic powder. This study examines the effect of aluminum powder additions in tin coatings. Following cold spraying of various Sn-Al mixtures over a wide range of gas pressures, unusual coating morphologies were observed. The study of these morphologies reveals two distinct deposition phases depending on spray pressure. The presence of submicron particles also supports the occurrence of a powder melting phenomenon during the spraying process.

Published: January 2023

Knowledge of thermal interactions between the substrate and deposited particles during cold spraying can shed light on coating formation and bonding mechanisms. In this study, a mathematical model based on the differential quadrature method was used to solve the hyperbolic heat conduction problem to predict the transient thermal evolution associated with the impact of a single particle. In addition, a 2D finite element model was developed to simulate the thermal and dynamic behavior of particle impact. The two models showed good agreement in predicting the maximum temperature at the particle-substrate interface. It was concluded that the proposed mathematical model could be used to predict the transient temperature of metallic and nonmetallic particle-substrate interfaces during cold spray deposition.
Suspension High Velocity Oxy-Fuel Spray of Graphene Nanoplatelets for Low-Friction Wear Protective Film Elements
Authors: Venturi F. , Hussain T.
Published: January 2023

In this work, suspension high-velocity oxyfuel spraying (SHVOF) with radial injection is shown to be a suitable technique for depositing graphene nanoplatelet layers on stainless steel substrates. The effect of feedstock injection parameters such as flowrate, injection angle, and position are investigated at different flame powers by means of high-speed imaging. In dry sliding wear tests, graphene layers on stainless steel exhibited a friction coefficient of around 0.1 after 1000 cycles and less than 0.3 after 2000 cycles. Compared to uncoated stainless steel, this is an order of magnitude improvement.

Published: January 2023

In this study, pure rutile TiO2 coatings are deposited on stainless steel substrates by very low-pressure plasma spraying (VLPPS). The spraying system was used in the reactive mode, injecting both titanium powder and oxygen gas to achieve nanosize particles. Optical emission spectroscopy showed that the interaction between Ti particles and O2 occurred in flight. Coating microstructure and phase composition were characterized at the surface and in the bulk with respect to operating parameters. Coating surfaces show typical cauliflower microstructure with many nanoparticles, while the microstructure below was found to change from binary to columnar as spraying distance increases.

Published: January 2023

The agglomeration process plays an important role in suspension plasma spraying (SPS), affecting the state of particles prior to impact and consequently the mechanical properties of the coated substrate. This paper presents the results of an investigation on the agglomeration of submicron YSZ particles sprayed from a water suspension. The shape and surface morphology of transient and final agglomerate structures was studied by injecting YSZ suspensions with a nebulizer into an inductively coupled plasma torch. It was found that particle agglomeration occurs in successive stages identified as cup or doughnut shaped agglomerates, polycrystalline particles, and amorphous or partially molten particles.
A Study of the Mixed Powders Interaction Behavior Upon Impact in Cold Spray
Authors: Chu Xin , Yue Stephen , Vo Phuong
Published: January 2023

In this study, two sizes of iron and stainless steel powders were binarily mixed into four groups with different weight percent fractions and the various mixtures and single-component powders were cold sprayed onto aluminum substrates. The deposition efficiencies (DE) of the powder mixtures and single-component powders were measured and are compared. The results show that the four binary mixtures exhibit different DE characteristics as a function of stainless steel wt% and that the small size mixtures have higher DE relative to the single-component iron powder. The difference is explained by particle-particle interactions (tamping and retention) that occur upon impact and only in the small size mixtures. The study also finds that changing spray parameters, such as feed rate, stand-off distance, gun travel speed, and gas temperature and pressure, has no effect on particle-particle interactions.

In this work, a 2D axisymmetric model of gas atomization at unsteady state that accounts for break-up and solidification is used to simulate laser melting of gas atomized powder. With an optimal nozzle width of 0.6-1 mm and a nozzle angle of 30-32°, the yield of fine 15-45 μm stainless steel powder, suitable for selective laser melting, is shown to increase from 20% to 35%. The effect of laser power on the melting channel width, microstructure, and mechanical properties of the sample is also investigated.
