Abstract

Purpose

The purpose of this study is to evaluate and compare the mechanical performance of FFF parts when subjected to post processing thermal treatment. Therefore, a study of the annealing treatment influence on the mechanical properties was performed. For this, two different types of Nylon (PA12) were used, FX256 and CF15, being the second a short fibre reinforcement version of the first one.

Design/methodology/approach

In this study, tensile and flexural properties of specimens produced via FFF were determined after being annealed at temperatures of 135°C, 150°C or 165°C during 3, 6, 12 or 18 h and compared with the non-treated conditions. Differential scanning calorimetry (DSC) was performed to determine the degree of crystallinity. To evaluate the annealing parameters’ influence on the mechanical properties, a full factorial design of experiments was developed, followed by an analysis of variance, as well as post hoc comparisons, to determine the most significative intervening factors and their effect on the results.

Findings

The results indicate that CF15 increased its tensile modulus, strength, flexural modulus and flexural strength around 11%, while FX256 presented similar values for tensile properties, doubling for flexural results. Flexural strain presented an improvement, indicating an increased interlayer behaviour. Concerning to the DSC analysis, an increase in the degree of crystallinity for all the annealed parts.

Originality/value

Overall, the annealing treatment process cause a significant improvement in the mechanical performance of the material, with the exception of 165°C annealed specimens, in which a decrease of the mechanical properties was observed, resultant of material degradation.

Abstract

Purpose

The purpose of this paper is to introduce the idea of green atmospherics and propose a conceptual framework for green service environment factors and a typology for green consumers.

Design/methodology/approach

This paper takes the form of a conceptual piece. and offers a new approach to green consumerism. Green atmospherics goes beyond many of the typical factors explored in previous service environment studies. The paper examines how many terms commonplace in the design and architectural literature can be translated into the marketing arena. Factors such as daylighting, recycling, offgassing, insulation, optimal energy performance and design for the environment are discussed.

Findings

The paper proposes that “going green” goes beyond having recyclable or even sustainable products, to an ideology that incorporates improving worker morale and retention, and giving back to the communities they are located in. Additionally, the paper makes a case for classifying green consumers based on a psychographic segmentation approach compared to the more traditional socioeconomic classification.

Originality/value

This paper offers a conceptual framework for assessing green atmospherics within service environments and proposes a green consumer typology that references “stimuli” versus “socio‐demographics” for categorization. A new categorization is proposed and the importance of this topic to consumers, practitioners and researchers are discussed.

Abstract

Shortly before the Second World War, a woman who had never accepted her orphan status, Gabrielle Bonheur Chanel, nicknamed ‘Little Coco’ by her father and known as ‘Coco’ to her relatives, became the first women in history to build a world-class industrial empire. By 1935, Coco, a fashion designer and industry captain, was employing more than 4,000 workers and had sold more than 28,000 dresses, tailored jackets and women's suits. Born into a poor family and raised in an orphanage, she enjoyed an intense social life in Paris in the 1920s, rubbing shoulders with artists, creators and the rising stars of her time.

Thanks to her entrepreneurial skills, she was able to innovate in her methods and in her trendsetting approach to fashion design and promotion. Coco Chanel was committed and creative, had the soul of an entrepreneur and went on to become a world leader in a brand new sector combining fashion, accessories and perfumes that she would help shape. By the end of her life, she had redefined French elegance and revolutionized the way people dressed.

Abstract

Purpose

The purpose of this paper is to examine the relationship between consumers' satisfaction with their health insurance and quality of life (QoL), the mediating role of perceived financial burden in this relationship, as well as the moderating effect of external locus of control (LoC) on the relationship between perceived financial burden and QoL among cancer patients.

Design/methodology/approach

A cross-sectional design was employed in order to collect quantitative data by means of a self-administrated questionnaire. Participants consisted of 387 conveniently selected consumers diagnosed with cancer in Iran. Furthermore, the questionnaire was translated into Persian using a forward–backward method. The model was tested using partial least squares structural equation modeling (PLS-SEM).

Findings

The results indicate that the more satisfied patients are with their health insurance, the higher QoL they experience, and this relationship is explained through reducing perceived financial burden in terms of direct and indirect costs of the disease. Although external LoC belief is negatively related to QoL, it buffers the negative association between financial burden and QoL.

Practical implications

Reducing the disparity between consumers' expectation and perception of the comprehensiveness of health insurance policies may relieve consumers' anxiety stemming from financial worries.

Originality/value

This paper fills a gap in the literature where consumers' perception about quality of insurance and its relationship with their QoL has received little attention so far.

Abstract

Purpose

The interruption of on-campus teaching and learning, due to the COVID-19 pandemic, forced universities around the globe to rethink their pedagogical models and adopt innovative strategies and approaches that enabled continuity of learning. Engineering schools and faculties were faced with the challenge of how to continue to engage students with the practical component of coursework, especially in terms of lab work and experimentation, which are mandatory requirements for degree awards.

Design/methodology/approach

This study documents how the Faculty of Engineering in a university in Oman engaged students with the practical component of their course during the pandemic by launching the remote DoIt@Home Lab. The DoIt@Home Lab approach included the design and development of video recorded labs, virtual labs, simulation exercises and DoIt@Home experiments which were provided to students as teaching tools and guides to conducting home experiments remotely.

Findings

This study presents the DoIt@Home Lab approach introduced to Year 2 Chemistry for engineering students. Students' grades improved by 11% over the previous year when the course was delivered face-to-face. Failure rates dropped by 8% while the number of students earning a 3.25 grade point average (GPA) or higher increased by 18%.

Originality/value

The DoIt@Home Lab for engineering courses could enhance students' learning experience and create an effective remote learning environment. While the DoIt@Home Lab was created to supplement on-campus activity in the event of a temporary disruption, it can also be used to supplement regular face-to-face program delivery.

Abstract

Purpose

This paper aims to study five vegetables extracts as possible additives to control bacterial growth on indoor waterborne paints. The extracts were obtained from the weeds Raphanus sativus, Rapistrum rugosum, Sinapis arvensis, Nicotiana longiflora and Dipsacus fullonum, used in traditional medicine as antimicrobial compounds.

Design/methodology/approach

Weeds extracts were characterized by Fourier transform infrared spectroscopy and UV–Vis spectrophotometry. Their antibacterial activity against Escherichia coli and Staphylococcus aureus was also determined. Afterward, selected extracts were incorporated in waterborne paint formulations. The paints’ antimicrobial activity was assessed against S. aureus, monitoring biofilm formation by environmental scanning electron microscopy.

Findings

As a general rule, results showed that tested paints were efficient in inhibiting biofilm formation, especially that formulated with Nicotiana longiflora.

Practical implications

The tested paints can be used to protect walls from microbial colonization, which shortened coatings’ useful life by discoloration and/or degradation. Concomitantly, indoor microbial colonization by aerosols could be also diminished. This is especially important in places that should have high standards of environmental hygiene, as in the food industry, health-care and sanitary centers.

Originality/value

The main value of this research was to study the antimicrobial activity of weeds extracts and to incorporate them in waterborne paints to diminish bacterial biofilm formation. This biofilm discolors and degrades the paint, and causes health problems. The use of natural compounds in coatings is increasing because of the convenience of using renewable sources, such as natural antimicrobials, in paint formulations.
