Condensates of stearic (St), palmitic (Pa) or myristic (My) acids with polyethylene glycols (PEG) 300, 400, 600, 2000 or 6000, are utilized as emulsifiers for kerosene ∓ in ∓ water pigment printing pastes. Pastes based on condensates of PEG 300 or 400 are unstable while the others are stable. Rheology of stable pastes, aside from those based on a commercial emulsifier, are of a non ∓ Newtonian, shear thinning ∓ thixotropic flow. The order of the flow properties of pastes enhanced are found. Cotton pigment prints using the nine pastes are sharp and of comparable handle, colour strength and color fastness to those based on a paste of either a commercial emulsifier or synthetic thickener (except for Pa∓6000). The pigment prints of 65/35 cotton/polyester are sharp only upon using pastes of commercial emulsifier, synthetic thickener, St∓600, St∓2000, St∓6000 and My∓2000. After 7 days of storing, all pastes are stable with increased apparent viscosities and induced color strength on both cotton and blended fabrics.

Optimal conditions for condensation of equimolar ratios of stearic acid (St) and polyethylene glycol (PEG) 400, i.e. 180°C, 8hrs and H₂SO₄, 4g/kg (reactants mixture), were utilized to condensate the equimolar ratio of stearic (St), palmitic (Pa) or myristic (My) acid with PEG 300, 400, 600, 2000 or 6000. Each of the fifteen condensates was formed by total conversion (83.5 to 84.1 %). Monoester–diester ratios of the condensates ranged from 4:1 to 49:1. FT – IR spectroscopy and hydrophilic lipohilic balances (HLB) of the condensates were also examined. The condensates had softening and hydrophilic properties of cotton fabric with no yellowing at concentrations of 30 and 50g/l in the presence or absence of DMDHEU (50g/l). The presence of DMDHEU improved the fabric resiliency.

However, the softening and hydrophilic properties of the fabric were inferior in the presence of DMDHEU rather than the absence. In comparison with a commercial softener, PEG 2000- or 6000-based condensates were higher in fabric wettability and pliability but lower in smoothness. Regarding CRA, only My-2000 was comparable to that of the commercial softener in terms of effect.

The inclusion of softeners (20 g/l), namely, Siligen VN (silicon based), Basosoft SWK (cationic), or Leomin NI (nonionic), in a dimethyloldihydroxy ethylene urea (DMDHEU, 50 g/l) finishing formulation of 65/35 cotton/polyester blended fabric, enhances the resiliency of the fabric, which is expressed as the dry wrinkle recovery angle (WRA). The fabric acquires the ability to keep a rose oil fragrance upon storage up to 3 months. Improving the WRA and acquiring the ability to keep the fragrance can be descendingly arranged as follows: Siligen VN>Basosoft SWK>Leomin NI. Increasing the Siligen VN concentration (0-30 g/l) in the finishing formulation is accompanied by a small increase in the WRA, and a noticeable enhancement in the ability to keep the rose oil fragrance upon storage. By increasing the rose oil concentration (100-300 g/l) in a perfumed bath of cross-linked/Siligen VN, the softened fabric is accompanied by a slight drop in the WRA, and a decreasing ability to keep the fragrance up to 3 months.

However, the extent of the fragrance is higher at higher rose oil concentrations, regardless of the storage time. The ability of the fabric to keep the fragrance can be attributed to solubilization and/or encapsulation of the perfume in the oleophilic segments of the softener, and its slow release with time, so that the smell can be sensed. This ability decreases after increasing the storage time up to 3 months, and depending on the type of perfume oil used, is descendingly arranged as follows: jasmine oil > rose oil > sandal oil.

This paper aims to present nonlinear numerical simulations using the versatile finite element (FE) analysis tool ANSYS and theoretical analysis based on code provisions to assess the load-carrying capacity of reinforced concrete (RC) beams under two-point monotonic static loadings.

Four quarter-size FE models with load and geometry symmetry conditions were constructed, the load-bearing capacity and associated mid-span deflections at critical points are verified against the full-scale experimental RC beams available in the literature. These developed FE models incorporated the tension stiffening effects and bond–slip behaviour. Theoretical analyses based on Indian standard code IS: 456–2000 and ACI 318–19 were also carried to verify the experimental and numerical predicted moments at critical loading points.

The load-deflection curves predicted through FE models exhibit closer corroboration with the experimental curves throughout the loading history. The contour plots for deflections, concrete principal stresses, reinforcement yield stresses are satisfactorily predicted by the FE models, which reveal the complete information of nonlinear behaviour of RC beams. The developed model well captured the initial and progressive crack patterns at each load increments.

The FE modelling is an efficient, valid and economical tool that is an alternative to the expensive experimental program and can be used to explore, analyse and fully understand the nonlinear response of RC beams under static loadings.

The ultimate moment capacity evaluated based on ACI 318–19 code provision show a better correlation with the experimental data as compared to the IS: 456–2000 code provision. The ultimate loads and associated centre-span deflections predicted by RN-2, RN-3, RB-12 and RB-16 FE model show a discrepancy of 1.66 and –0.49%, –4.68 and –0.60%, –9.38 and –14.53% and –4.37 and 4.21%, respectively, against the experimental results, which reveals that the developed ANSYS FE models predict consistent results and achieved a reasonable agreement with the experimental data.

Although the academic literature provides extensive insight into the motivations for the unethical use of information technology in online classes, little is known about how perceived justice, the opportunity to cheat and spiritual legitimacy mitigate unethical behavior among young academics. The purposes of this study are two folds: first, to determine how perceived lecturers’ justice and opportunity to cheat may mitigate academic misconduct in online classes, and second, to evaluate the moderating effect of spiritual power on the relationship between perceived lecturers’ justice and opportunity to cheat and academic misconduct.

This research was conducted at universities in three Southeast Asia countries, including Indonesia, Malaysia and Thailand, with a total of 339 respondents. The research questionnaire was distributed using Google Forms. The analytical method used to test the research hypothesis is moderated regression analysis (MRA).

The findings of this study reveal that spirituality moderates the relationship between lecturer justice and the opportunity to cheat online. Even though the justice level of the lecturer is low, individuals with relatively high spirituality will show much less cheating behavior than when there is a low level of lecturer justice and a low level of student spirituality, and vice versa.

Cheating occurs when students develop an intention to cheat, which leads to actual involvement in cheating, meaning that theoretically, the findings extend the fraud triangle theory. In addition, the practical implications of this research are that lecturers need to conduct fair teaching, such as transparency of exam conditions, assessment, the right to an opinion and supervision during exams, consequently, the students cannot cheat. Spirituality is also an essential factor that can reduce online cheating, so instilling spirituality in specific courses is a fruitful solution.

The contributions of this study are twofold. First, this study gives testable theories on how spiritual help works. Second, this study offers tailored and more humanistic assistance, such as a mechanism that adjusts to the academic world’s usage of more positive technologies. This study contributes to the literature on online cheating in higher education across three Southeast Asian nations (Indonesia, Malaysia and Thailand).

The study scrutinizes the direct and indirect association between absorptive capacity as the independent variable and green innovation adoption and sustainable performance as the dependent variables. Similarly, the study assessed the mediating role of green innovation adoption between absorptive capacity and sustainable performance. The research also evaluates green organizational culture and environmental regulation as moderators.

The current study applied partial least squares structural equation modeling (PLS-SEM) and administered a questionnaire to general managers and department directors in 4- and 5-star hotels. Quantitative research was employed as the chosen method.

The PLS-SEM analysis revealed that absorptive capacity has a positive impact on the adoption of green innovation. Furthermore, each sub-dimension of sustainable performance acts as a partial mediator in this relationship. Also, our study showed that environmental regulations and green organizational culture moderate the link between absorptive capacity and the adoption of green innovation.

The research primarily emphasizes that Oman’s hotel business may limit its applicability to other nations with distinct cultures, economies, legal frameworks for the environment and cultural norms.

To build an integrative and a comprehensive framework, the present work combines resource-based view (RBV) theory, dynamic capabilities (DC) theory and triple bottom line (TBL) theory. This method aims to improve understanding by combining several points of view on resource management, skills, and environmental sustainability.

A wide range of clays are presently available in Egypt. These clays are potentially economic substances as they contain minerals such as montmorillonite, kaolinite and illite. The x‐ray flourescence and the thermal gravimetric analysis (TGA) were calculated for the clay sample under consideration. The modification of the clay surface was achieved by using two different organic substances such as stearic acid and poly (methacrylic acid) solutions. It was found that the modification process improved the pigmentary properties of this clay.

We had just got over the shock of seeing the demise of the well respected name of “Berger Industrial Coatings”, now trading as Herberts (see this page, September 1987), when the parent company Hoechst made its announcement just before Christmas that Berger, Jenson & Nicholson Ltd is being sold to Williams Holdings Plc.

The aim of the study is to test the relationship between academic backgrounds, parents’ involvement and absorption capacity with academic performance through the mediation effect of appreciation culture.

The study was conducted on university students from Pakistan. Data were collected through personal visits using self-administered questionnaires. A total of 394 students participated in this study. The data analysis for this study was conducted using Smart-PLS 4.

The findings of the study confirmed a significant association between academic backgrounds, parents’ involvement and absorption capacity with academic performance. Results also confirmed a significant mediation of appreciation culture between independent variables’ academic backgrounds, parents’ involvement and absorption capacity with dependent variable academic performance.

Presently, there is a shortage of comprehensive studies that investigate the collective influence of appreciating culture, academic backgrounds, parental involvement and absorption capacity on academic performance. Moreover, there is a lack of exploration of the implementation of the theory of reasoned action (TRA) along with the theory of academic performance (TAP) in this particular setting. This research aims to fill these gaps by investigating these aspects within an integrated framework, providing significant insights into the existing body of literature.

The purpose of this paper is to investigate the influencing factors of generation Z (Gen Z) consumers’ revisit intentions to robotic restaurants in the post-pandemic times.

Using a sample of Gen Z consumers with dining experiences in an Indian restaurant using service robots, the study empirically tests a research framework based on stimulus–organism–response theory.

The study explains how Gen Z consumer’s perceptions of functional attributes (i.e. perceived usefulness and perceived ease of use), socio-emotional attribute (i.e. perceived safety) and relational attribute (i.e. trust) shape their attitude, which in turn leads to their evaluations of performance outcomes and intention to revisit the robotic restaurants. The findings also indicate that perceived risk reduction of viral infection moderates the impact of performance outcomes on revisit intention.

Due to the outbreak of COVID-19 pandemic, the changing preferences of consumers have resulted in an increase in demand for restaurants offering robotic services. To support the long-term viability of service robots in restaurant services, the current study investigates what elements of service robots can determine consumers’ intentions to revisit the robotic restaurants during post-pandemic times.
