Abstract – Advances in internet-based communication and information technology, in the digital era bring major changes in various aspects of life, so that agribusiness actors are also competing to create a digital marketing system in order to maintain or improve the sustainability of their business. This study aims to analyze the factors that influence the use of e-marketing on consumer satisfaction at Hartanimart.com. The research approach is descriptive quantitative, through survey activities with descriptive tabulation methods and PLS-SEM data analysis processed with the help of Excel 2010 software and Smart PLS software version 3.2.1. The findings show that of the 3 hypotheses tested there are 3 accepted/proven hypotheses based on the value (t-test > 1.96) and value (p-value < 0.05), namely H1 = usefulness, H2 = ease of use, H4 = norm subjective influence significantly on the use of e-marketing on online transaction activities at Hartani Farm. Other hypotheses were rejected such as H3 = attitude of use has a significant effect on the use of e-marketing on online transaction activities at Hartani Farm and H5 = factors of e-marketing users have a direct and indirect effect on the level of consumer satisfaction on online transaction activities at Hartani Farm. This indicates that Hartani Farm consumers directly or indirectly do not feel satisfaction from the factor of using e-marketing. While the subjective norm factor has a direct influence on consumer satisfaction. For this reason, the management of the Hartani Farm company must be more creative in finding other ways or breakthroughs in its marketing program activities so that more consumers buy their products and win business competition in the future.Keywords : Customer Satisfaction, Use of e-marketing

Authors: Sabir Samina , Suleria Sagher , Sibghatullah Amena , Shamshir Musarrat
Published: September 2022

This paper explores the effect of human capital and technology on economic growth in Asian countries while considering economic development. The paper expands the Solow Growth model by further incorporating the import of machinery and equipment reflecting total factor productivity. Panel data for 30 Asian countries has been used over 1995-2015. Due to the endogeneity problem in human capital and other variables, the System Generalized Method of Moment (GMM) is used to address this problem. Empirical results reveal that human capital and technology have increased economic growth in the total sample of Asian countries. Furthermore, the sample has been disaggregated into high-income (HI) and low-income (LI) Asian countries. Our findings determine that human capital and technology are reflecting a positive and statistically significant role in enhancing economic growth in both samples of countries. However, the magnitude of the impact is high in HI Asian countries relative to LI Asian countries, respectively. When the import of machinery and equipment are replaced with patents, a positive and insignificant results are obtained for LI countries because these countries have lacked legal systems, but a positive and statistically significant relationship is observed for HI Asian countries.

Published: September 2022

The construction industry has experienced a dramatic boom in theeconomy over the last two years, due to the significance of CPEC in Pakistan. In the project’s performance, the role and concept of Institutional Environment have been extensively studied in previous literature. However, the analysis of these strategic constructs in construction firms has been minimal. Still, a gap exists in institutional factors concerning project performance. This paper aims to address this gap posits that Institutional Environmental Factors (IEFs) may impact the performance of the construction projects; also, there may be some factors that can impede or promote the performance of these projects. Data were collected from a sample of some construction firms’ management teams through semi-structured interviews. Study results suggested that coercive & normative factors of the institutional environment have a significant impact on the project performance concerning time delays and cost escalation. However, mimetic factors have less impact. This study also tries to assimilate the importance of institutional factors with the policy-making aspects of construction firms which can affect the performance of the projects. Future implications and limitations of the study are also discussed.

Creating Public Value Through Reputation Management
Authors: Irfan Asmara , Sami Abdul
Published: September 2022

The central idea of this research is to find out how reputation management creates public value. The value system of an institution is very much important for its reputation. Reputation is associated with an institution’s ability to assure its employee’s requirements. An institution’s reputation explains its members’ opinion aboutits institution’s proficiency to create values comparative to its opponents. Universities do not give attention to managing their reputation in the long run. Public value can be considered a new thought for public sector organisations to manage their reputation. The public value of universities includes those ethics of an organisation that offer quality services to its students. To remain in the competition, universities have to handle their reputation by fulfilling their students’ demands. Reputation management is much argued in the business sector, and public value is discussed in different public organisations. Few researchers have discussed the relationship between reputation management and public value in the education sector. This study uses proportional random sampling. The sample for this study includes five public universities in Pakistan. To evaluate the collected data Partial Least Squares Structural Equation Modeling was used. The findings of this study confirm that there is a positive relationship between university reputation and public value.

Authors: Shaikh Sadia , Sultan Faisal , Asim Muhammad
Published: September 2022

Big-data analytics are treated as the future of technology andessential for the retail sector. The technology is especially beneficial for optimising daily operations and supply chain practices. However, there is a wide gap in the related literature in developing and Asian countries on this subject. On the other hand, retailing is one of the fastest-growing industries globally. Therefore, this study is specifically designed to understand the role of big data concerning the organised retail sector of Pakistan. The study’s primary objective is to assess the significance of technology in augmenting assortment strategies. However, the mediation of advanced algorithms and moderation of skilled data scientists are included in the research construct to increase research relevance to the pragmatic world. Results were determined by applying Partial least square structured equation modeling (PLS-SEM). The findings indicated that big data is a prolific constituent to optimise assortment in the retail sector of Pakistan. However, the technology would not produce the desired results without applying advanced algorithms. This study accentuates the actuality that advanced algorithms are essential to be analysed to use big-data most effectively to retrieve new information. Further studies may also be conducted in devising a comprehensive model which includes all the potent variables associated with store-layout design

Authors: Qurat ul Ain  , Ellahi Abida
Published: September 2022

This study explores how perceived crowding affects customers in the service sector. A Semi-structured interview guideline was developed to assemble data from forty customers of banks and telecom franchises. Analysis of the research was carried out by using qualitative research software Atlas. The findings suggest that perceived crowding, including social and spatial crowding, impacts customers behaviour emotionally and psychologically. They demonstrate altered behaviour when present in a crowded environment. Further, it was also found that certain elements helped customers tolerate the effects of spatial and social crowding; either types of customers, environment/infrastructure, or Frontline Service Employees behaviour during service attainment. Additionally, following the assumptions of the theory of psychological reactance, this study proposed a research model for future empirical studies. Findings also suggest that top management must consider the impact that perceived crowding produces on customers. Limitations and future research directions and theoretical and practical implications are also discussed.
Workplace Bullying and Organizational Deviance : Does Gratitude Matter?
Authors: Ashraf Fatima , Khan Muhammad Asif
Published: September 2022

Two objectives guide this study: first, to examine whether organizational deviance is a consequence of workplace bullying, and second, to investigate a possible moderating effect of gratitude on the relationship between workplace bullying and organizational deviance. Variables were tapped using the Negative Acts Questionnaire, Organisational Deviance Measure, and Gratitude Questionnaire (GQ6). This study uses a correlation-causal design; data were drawn from a sample of 215 workers employed in telecom organizations and higher education institutes and universities based in Islamabad and Rawalpindi. Linear and hierarchical regression techniques were used to test the hypothesized direct and moderating effects. Results confirmed both hypotheses, implying that workplace bullying offsets organizational deviance in bullied employees and that gratitude moderates the relationship. Theoretically, the study contributes to the current literature by signifying that workplace bullying triggers deviance in employees and that gratitude is an important variable that lessens the undesirable triggering of workplace deviance in bullied employees. Managers should create awareness about bullying and deviant acts at work and assert gratitude within the organizational environment through training and workshops to lessen bullying incidents and offset unwanted bullying outcomes. They are also advised to minimize bullying and its subsequent effects by establishing clarity in work design.

High End Hard Metal Coatings for the Toughest Demand in Paper Industry
Authors: Jungklaus H. , Blutmager A.
Published: September 2022

Raising demands in industry lead to the request of different and better paper quality. New paper types like e.g., liquid food packaging (lfp) will replace former solutions like Tetrapak, magazine papers will be produced much cheaper on different machine designs. Since certain paper properties like roughness, printability, … still remain or step up in quality level. One machine component influencing the paper properties strongly is the calender with its extremely hard, coated roll surfaces. The hard metal coating on the calender rolls can determine the later paper quality significantly. The current work describes investigations on certain WC based HVOF coatings, which later will be in contact with the paper under high temperatures, extremely high load, and steam environment. Coating design from carbide particle size, metal matrix and other factors like apparent density and sintering grade were studied under real life influences. The various coating versions were compared in a slurry test using the same fines as added in the paper production process for increasing brightness and tear strength. Interesting results are discussed on technical, but also economical basis.

Published: September 2022

Carbides are interesting materials for many wear resistant and high temperature applications, however, the production of coatings with these materials represents a significant challenge as they tend to oxidise or decompose into gaseous phases when they are exposed to extreme thermal spray conditions. An innovative method merging suspension and solution precursors was developed to allow the production of carbide composite coatings. Suspensions of carbides and borides were modified with the addition of oxide precursors to obtain composite coatings by high-velocity oxy-fuel (HVOF) thermal spray. The transformation of these oxides precursors and their subsequent melting during spraying contribute to protect the carbides from oxidising conditions, avoid their degradation during the spray process and support the development of dense coatings, as it was demonstrated by dispersive X-ray spectroscopy and X-ray diffraction analysis. The relationships between processing and microstructure were studied in terms of porosity phase distribution and mechanical properties, proving that this novel approach could be applied to obtain coatings of materials that are prone to decompose during thermal spraying.
Perspective of 3D Near-Net-Shape Additive Manufacturing by Cold Spraying: An Empirical Study Using Pure Al Powders
Authors: Sokore M. , Wu H. , Li W. , Raoelison R.-N. , Deng S. , Liao H.
Published: September 2022

Cold Spray is a solid-state Additive Manufacturing process of 3D near-net-shape parts which requires the implementation of a good spraying strategy and the choice of the right operating parameters. This paper is the result of empirical studies on the determination of the optimal processing conditions (spraying and kinematics) for the Cold Spray Additive Manufacturing (CSAM) of pure aluminum powder using a stable layers building strategy. Vertical 3D deposits (thick walls) with a height and thickness of 13-100 mm and 5-11 mm, respectively, were obtained through a series of tests that consider an effect of some kinematic parameters. The visual analysis of the deposits shows that the nozzle traverse speed as well as middle/edge pass number ratio constitute the two most influential parameters on the final shape of the deposits (flatness and straightness). All these results prove the potential of the Cold Spray Additive Manufacturing (CSAM) process as fast 3D additive method using micron sized powders, and particularly for Al powder.
A Physics Based Model for Ultrahigh Strain Rates in Cold Spray

Published: September 2022

Thermal spray technology keeps attracting several industries in both the manufacturing and repair sectors, thanks to its practicability and its reasonable processing time. Moreover, different kinds of materials can be successfully deposited to form coatings with potential excellent thermo-electro-mechanical properties. The resultant coating microstructure is completely different from the wrought powder material before the deposition process. In the case of metallic materials, the thermomechanical characteristics are quite dependent on the deposition conditions monitored from the spraying setup. One can mention gas temperature, impact velocity and angle, material combination, surface state, particles size, etc. Hence, one major factor which influences the final coating microstructural state is kinetic energy. In fact, in such processes where high velocity deposition is observed, intense grain refinement and sharp increase of the dislocation density are an outcome that is tightly related to high temperature and severe plastic deformation. Prediction of the mechanical properties of the produced coating is usually carried out using phenomenological models that describe very well the relationship between stress and strain under different conditions of temperature and strain rates. Most of these models fail, however, to describe the effect of the deformation mechanisms observed at ultra-high strain rates such as the viscous drag regime of dislocations or further the weak shock load regime, scenarios commonly observed in such processes. In the present paper, we present an enhanced physics-based model to describe the stress strengthening of metals upon impact and associated microstructure changes. We show that the model can accurately represent the desired effect of the dislocation drag. Modelling of the impact of a single copper particle onto a copper substrate is carried out to show the capability of the model to predict grain refinement and dislocation network modification.

Thermally sprayed WC-based hardmetal coatings offer high hardness, good sliding wear and abrasion performance and find large applications in mechanical engineering, valve construction, or offshore applications. WC-Co coatings are mainly produced by high-velocity oxy-fuel spraying (HVOF) from conventional spray feedstock powders. In our previous work, the potential of the suspension-HVOF spraying (S-HVOF) to produce dense-structured WC-12Co coatings has been shown. Significant work was devoted to the development of appropriate aqueous hardmetal suspensions starting from commercially available fine WC and Co raw powders feedstock. This contribution proposes a step forward in the development of the S-HVOF WC-12Co coatings and evaluation of their microstructural and tribological properties. Suspension spraying trials were carried out using gas-fuelled HVOF TopGun system. For comparison purposes, liquid-fuelled HVOF K2 was employed to spray WC-12Co coatings starting from commercial available spray powder. Microstructural characterization, X-Ray diffraction and microhardness of the coatings were evaluated. Oscillating sliding wear tests were conducted against sintered Al2O3 and WC-6Co balls. The sliding wear performances of the WC-Co sprayed coatings were discussed in term of the microstructure, phase composition and coating-ball test couples.

Authors: Venturoli A. , Conoscenti G. , Chiesa R.
Published: September 2022

The aim of this work is to study the effects of the titanium plasma spray (TPS) coating process on the fatigue resistance of a titanium-6Al-4V substrate. The combination of TPS processes and Ti alloy substrate is widely applied on components intended for cementless total hip replacement (THR). In order to understand the coating process mechanism behind the implants’ fatigue resistance decrease, one air-developed coating (Ti-APS) and one controlled atmosphere developed coating (Ti-CAPS) were considered. The effects of the most representative parameters of the plasma spray process on the fatigue resistance were analysed: the sandblasting process, the plasma and the coating powder. Fatigue resistance studies were performed by means of rotating bending fatigue testing. After fatigue failure specimens underwent morphological analyses both on the primary crack surface and on the cross-sectional area complemented by of the metallographic analyses of the coating. The titanium substrate fatigue resistance decreased after being blasted with direct relationship with the grain size. Ti-CAPS process showed a relatively limited further influence on the fatigue resistance reduction with respect to only sandblasted samples. By contrary a remarkable fatigue limit decreased was seen for Ti-APS coated samples against Ti-CAPS and simply sandblasted samples. The experiment pointed out the critical importance of cracks oxidation as a fatigue failure driving factor.

Published: September 2022

When compared with conventional thermal spraying processes, thermal spraying of suspensions allows to produce coatings with outstanding properties in terms of microstructure, surface topography, and phase compositions, as well as mechanical, electrical or tribological requirements. The use of suspensions as feedstock results in an almost unlimited flexibility in terms of chemical composition of the sprayed coatings. Moreover, thermal spraying of suspensions is a promising technique for processing expensive raw materials. Zn2TiO4 coatings are only one example where the high costs of blended oxide powders as feedstock material hinders the market introduction, whereas outstanding electrical properties and photocatalytic activity of thermally sprayed Zn2TiO4 coatings are of great interest for various industrial applications. In this work, single oxide ZnO and TiO2 raw materials as well as a Zn2TiO4 feedstock powder were used to develop tailored aqueous suspensions suitable for thermal spraying. To follow the formation of the compositions in the system ZnO-TiO2, differential thermal analysis (DTA) and thermal gravimetry (TG) measurements were performed. Preparation routes of stable suspensions with low sedimentation rates, low viscosity and good flowability are discussed. Exemplary microstructures and phase compositions of sprayed coatings are shown. In all sprayed coatings, the Zn2TiO4 phase has been formed during Suspension High Velocity Oxygen Fuel Spraying (S-HVOF). This work demonstrates the potential to develop appropriate cost-efficient suspension feedstocks from single oxide raw materials to obtain Zn2TiO4 coatings.

Authors: Vackel A. , Peleg E. , Varga J. , Blea M. , Schmidt C. , Gildersleeve E.
Published: September 2022

This paper presents the results of two metals coatings, molybdenum and tantalum, prepared by Controlled Atmosphere Plasma Spray (CAPS) onto Al 6061 substrates that were thermal cycled to calculate the effective coating modulus. Traditional uniaxial tensile testing samples were prepared from thicker duplicate coatings for comparison, as well as to measure thermal expansion properties and oxygen and nitrogen content. The molybdenum samples cut from thicker coatings were un-able to be tensile tested due to their fragility. Thermal cycle testing of molybdenum on an Al 6061 substrate was found to have a modulus approximately 18 to 19% of literature values for bulk molybdenum using the bi-layer beam thermal cycling method. Additionally, non-linear modulus behaviour was observed in the molybdenum sample when enough thermal strain was induced to shift the coating from a compressive to tensile stress state. The tantalum coating was found to have a modulus approximately 42 to 46% of literature values for bulk tantalum using the bi-layer thermal cycling method. Traditional tensile testing measured a modulus approximately 44 to 46% of bulk, which shows good agreement between the two methods and supports that the bi-layer thermal cycling method is valid for plasma sprayed refractory metal coatings.

Published: September 2022

Deposition of hybrid plasma-sprayed coatings employing both dry powder and liquid feedstocks enables preparation of innovative coating architectures. Using this technique, miniature domains of additional (secondary) material may be introduced via the liquid feedstock route into the more conventional powder-deposited coating, providing potential benefits for the coating functionality. In this contribution, we have explored the tribological properties of hybrid coatings sprayed from alumina powder with additions of chromia (Cr2O3), zirconia (ZrO2), yttria-stabilized zirconia (YSZ), and titania (TiO2) delivered from liquid feedstocks. The coatings were subjected to dry sliding wear testing and a subsequent analysis of the wear tracks to determine their wear resistance and coefficient of friction, as well as a qualitative assessment of the wear mechanisms. The hybrid coating doped with the chromia addition matched the remarkable wear resistance of highly-dense suspension-sprayed coatings. This is a significant result, especially when considering the order of magnitude better production efficiency of the hybrid coatings.

Authors: Yu P. , Fan N. , Yin S. , Lupoi R.
Published: September 2022

High entropy alloys, as a novel alloy system, demonstrated excellent mechanical performance. However, despite its excellent mechanical performance, the strength-ductility trade-off effect still limit its performance. In recent decades, it has been found that heterogenous or gradient microstructure can efficiently solve the conflict. Cold spray is a promising method to create heterogenous microstructure with high efficiency and low cost. In this work, equiatomic FeCoNiCrMn HEA was deposited by cold spray and the microstructure was systematically investigated by transmission electron microscopy (TEM) and transmission Kikuchi diffraction (TKD). In cold spray, a gradient microstructure was formed and segregated Ni and Mn in starting particle were also redistributed. Moreover, twinning in ultra-fine nanograins were detected in the region close to the impact interface. Compared with severe deformation of other low SFE metals, for FeCoNiCrMn HEA, twinning in nanograins also highly related to the grain size.

Published: September 2022

The HVOF sprayed WC-CoCr coatings are widely spread due to their excellent resistance against wear and corrosion. These coatings are one of the most suitable alternatives for hard chromium in many applications. Within the research project, the most suitable hard chromium alternative for hydraulic devices in aircraft is being developed and tested. This application is highly demanding not only on the functional properties of applied coatings but also on the surface quality. Grinding and polishing of the coating are not sufficient, to achieve the necessary surface properties. This study aims to optimize the superfinishing process of HVOF sprayed WC-CoCr coating. The achieved surface quality is primarily measured using profilometry. With optimized surface preparation, the tested parts for aircraft hydraulic parts are treated and tested for leakage of operating fluids and high cyclic lifespan.
