This study aims to conduct a systematic literature review to investigate the mental health problems during COVID-19 and the role of nutrition in minimizing mental and health-related issues during COVID-19.

A literature search was done electronically on April–May 2022 in the databases Google Scholar, PubMed and Cochrane Library, reviewing all the articles published in English. There were no limitations for the study (such as study design, region or any time frame). The quality assessment was done. The beginning database search picked out a total of 654 articles, 47 in PubMed, 575 in Google Scholar, 22 in Cochrane Library and 10 records from other sources. A total of 565 (duplicates found 89) were found after removing the duplicated articles, after reading the title and abstracts were further decreased to 88 full-text articles. These 88 studies went for full-text analysis, which excluded 56 studies and generated a final 32 articles for systemic analysis. The quality of the included study for the systematic review was assessed in two ways: one is evidence-based and another one on the JBI checklist.

People in social isolation and home quarantine suffer from severe anxiety, stress, depression, loneliness, anger and panic attack. During COVID-19, the vital role of diet and nutrients in mental health has been acknowledged and helps mitigate COVID-19 infection. Many studies showed stress and anxiety due to increased unhealthy eating and lifestyle practices.

This review will explain the interlink between diet and mental health because what we eat and think is interconnected with the gut–brain axis. The dietary elements and psychobiotic help in improving the immune system and psychological distress during the pandemic. This paper describes the role of different nutrients, psychobiotics and phytochemicals, to minimize mental and health issues during the COVID-19 pandemic. This paper also contains a balanced diet plan to withstand COVID-19.

The purpose of the study is to analytically as well as numerically investigate the weight of throughflow on the onset of Casson nanofluid layer in a permeable matrix. This study examines both the marginal and over stable kind of convective movement in the system.

A double-phase model is used for Casson nanofluid, which integrates the impacts of thermophoresis and Brownian wave, whereas for flow in the porous matrix the altered Darcy model is occupied under the statement that nanoparticle flux is disappear on the boundaries. The resultant eigenvalue problem is resolved analytically as well as numerically with the help of Galerkin process with the Casson nanofluid Rayleigh–Darcy number as the eigenvalue.

The findings revealed that the throughflow factor postpones the arrival of convective flow and reduces the extent of convective cells, whereas the Casson factor, the Casson nanoparticle Rayleigh–Darcy number and the reformed diffusivity ratio promote convective motion and also decrease the extent of convective cells.

Controlling the convective movement in heat transfer systems that generate high heat flux is a real mechanical challenge. The proposed framework proved that the use of throughflow is one of the most important ways to control the convective movement in Casson nanofluid. To the best of the authors’ knowledge, no inspection has been established in the literature that studies the outcome of throughflow on the Casson nanofluid convective flow in a porous medium layer. However, the convective flow of Casson nanofluid finds many applications in improving heat transmission and energy efficiency in a range of thermal systems, such as the cooling of heat-generating elements in electronic devices, heat exchangers, pharmaceutical practices and hybrid-powered engines, where throughflow can play a significant role in controlling the convective motion.

The purpose of this study is to examine the influence of rotation and varying gravitational strength on the onset of thermal convection in a porous medium layer numerically. The porous layer is acted to uniform rotation and inconsistent downward gravitational field which changing with depth from the layer. The authors presented three categories of gravitational strength deviancy, namely, linear, parabolic and exponential.

The higher-terms Galerkin weighted residual procedure is applied to get the eigenvalue of the problem.

The results illustrate that both rotation parameter and gravity variation parameter suspend the arrival of convection. The measurement of the convection cells decreases on enhancing the rotation parameter and gravity variation parameter.

It is also found that the scheme is more stable for category exponential, whereas it is more unstable for category parabolic.

Generating meaningful employment has become a major concern for countries across the globe to break the vicious circle of poverty. Employment creation becomes more intricate in a developing economy like India where the population is at an incessant rise, without a simultaneous increase in the employment generation. In the event of situations of mounting unemployment, micro small and medium enterprises (MSMEs) being largely labour-intensive have been claimed as a significant contributor in an economy’s development to induce employment generation. The study at hand is an attempt to gauge the overall contributions of MSMEs in employment creation in Assam, a developing region of the Indian sub-continent. However, most importantly, the purpose of this paper is to determine if men and women are differently employed in the sample MSMEs and if the pattern of employment creation is different across male and female-owned sample MSMEs.

The study is based on a uniquely large sample of 320 MSME entrepreneurs with an equal representation of 160 each from male and female entrepreneurs. Secondary data sources were also consulted. Study areas comprising Kamrup-Metropolitan and Kamrup-Rural, depicting both urban and rural Assam, respectively. The choice of activities undertaken by the entrepreneurs includes a wide variety of 12 activities pertaining to all the MSME entrepreneurs in general and certain gender-specific in particular. The two hypotheses (H01 and H02) formulated were tested using the Chi-square test and the Mann-Whitney U test. Furthermore, the growth rate of employment generation in Assam along with the growth rate of the number of MSMEs established and investment made by the MSMEs were computed.

The calculated growth rate of employment creation, capital investment and MSMEs established were found to be positive. Based on the results of the Chi-Square test and Cramer’s V test, this paper establishes a strong association between the MSMEs and the total employment generation by the sample entrepreneurs (H01). The primary data suggested that 320 MSMEs are Employing 2,766 people in the study area with an average of 8 people per unit. Employment in the service sector is higher than the manufacturing units with an average of 4 people per unit. Another vital finding of the study professed that the women-owned MSMEs have a relatively lesser number of people (32.2%) employed than their male counterparts (67.8%). The mean rank of male entrepreneurs is considerably higher (211.49) testifying a higher employment creation by the male-owned MSMEs than the women-owned (H02). Moreover, women (33.4%) are thinly employed than men (66.5%). Women entrepreneurs were seen to have mostly limited themselves in micro-units followed by small-units. In terms of the nature of employment, full-time employees (81.8%) supersede part-time employees (6.6%). The pattern of self-employment is equal (5.8%) across both male and women entrepreneurs. MSMEs have been well identified as an impeccable answer to mitigate the problem of mounting unemployment.

The novelty of the study lies in its meticulous and explicit understanding of the employment scenario in Assam by the MSMEs. Empirical works on employment creation by the MSMEs in Assam were fundamentally based on secondary data sources. The study fills in the gap by providing a holistic picture of employment creation based on both primary and secondary data, but prominently on the primary. The study accounts details about the nature of MSME employment, the gender of the MSME employees, employment creation by male and female MSME entrepreneurs, the growth rate of MSME employment and self-employment to name a few

The purpose of this study is to explore the impact of advertising, brand-related-stimuli, on the dimensions of sensory, emotional and intellectual brand experience.

The study is divided into two parts. In the first part, the objective is to examine antecedents to brand experience dimensions for umbrella brand and product brand using an experimental study; in the second part, the relationship among brand experience dimensions, brand experience evaluation and brand loyalty was examined using structural equation modeling by incorporating the measures after exposure to advertisement for both types of brands.

Based on a 2 × 2 factorial design, the results confirm that the main effect of advertisement exists on sensory, emotional and intellectual brand experience. For product brand, brand experience evaluation was mediator between both intellectual brand experience and emotional brand experience with brand loyalty. The effect of interaction between branding strategy and advertisement was not significant. For an umbrella brand, brand experience evaluation acted as a mediator between emotional brand experience dimension and brand loyalty. For product brand, brand experience evaluation acted as a mediator between both intellectual brand experience and emotional brand experience dimension with brand loyalty.

The research has implications with regard to the antecedents and consequences of brand experience and offers implications for branding strategy.

The present study is integrated and comprehensive, as it covers various facets of brand experience.

This study aims to synthesize two different benzoxazines (Bz) monomers using bio-based and petroleum-based primary amines, respectively, and they have been compared to study their thermal and mechanical performances.

A bio-based bisphenol, Divanillin (DiVa), was formed by reacting two moles of vanillin with one mole of ethylenediamine (EDA) which was then reacted firstly with paraformaldehyde and EDA to form the benzoxazine DiVa-EDA-Bz, and secondly with paraformaldehyde and furfuryl amine (FFA) to form the benzoxazine DiVa-FFA-Bz. The molecular structure and thermal properties of the benzoxazines were characterized by fourier transform infrared spectroscopy and nuclear magnetic resonance (1H,13C) spectroscopies, differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA), respectively. The benzoxazines were further coated on mild steel panels to evaluate their mechanical properties and chemical resistance.

The DSC results of DiVa-FFA-Bz showed two exothermic peaks related to crosslinking compared to the one in DiVa-EDA-Bz. The DiVa-FFA-Bz also showed a higher heat of polymerization than DiVa-EDA-Bz. The TGA results showed that DiVa-FFA-Bz exhibited higher thermal stability with a residual char of 54.10% than 43.24% for DiVa-EDA-Bz. The chemical resistance test results showed that DiVa-FFA-Bz showed better chemical resistance and mechanical properties due to its higher crosslinking density.

This study shows the use of bio-based materials, vanillin and FFA, for synthesizing a benzoxazine resin and its application at high temperatures.

The objective of the paper is to explore the relationship among perceived quality value, hedonic value, social value, price value, customer engagement and customer-based brand equity using stimulus-organism-response (S-O-R), customer engagement and customer-perceived value theories for digital payment apps. In addition, the study examines the mediating role of customer engagement between customer value dimensions and customer-based brand equity and analyzes the moderating role of age.

Partial least squares-based structural equation modeling was used to test the proposed hypotheses through a sample of 316 respondents who used digital payment apps.

The findings indicate that customer engagement mediates the relationship between customer value dimensions and customer-based brand equity. Age does not moderate the relationship between customer value dimensions and customer engagement. The study confirmed the pronounced effect of specific paths for various age groups.

This study contributes novel insight to S-O-R, customer engagement, and customer value research.

This study aims to examine the impact of customer brand value dimensions on relationship marketing dimensions through consumer hope in the context of digital payment applications (apps) services. The study considers the role of consumer engagement using a moderated mediation, and applies customer perceived value, affect theory of social exchange and relationship marketing theories.

The study is based on data collected from 301 digital payment app users. Structural equation modeling results were analyzed using Smart PLS. The authors performed moderated mediation, with different levels of customer engagement as a moderating variable, using Model 8 of PROCESS. The authors considered customer perceived value dimensions, digital quality value, perceived value, hedonic value and social value as antecedents to consumer hope and explored the role of trust, commitment and continued usage as a consequence of consumer hope.

Three levels of perceived consumer value, digital quality, price value and social value, positively influenced consumer hope, which has positively influenced trust, commitment and continuance usage. Using moderated mediation analysis, consumer hope influenced continuance usage through trust at different levels of engagement, but consumer hope did not influence continuance usage through commitment at different levels of engagement.

The study highlights the role of consumer hope in linking customer value dimensions with relationship marketing dimensions. The study can guide managers to ensure continued usage of digital payment apps, which is a strategic objective. The results are relevant for the digital setting.
