Abstract

Purpose

The aim of this study was to prepare antibacterial capsules and transfer them to cotton fabrics using the impregnation method.

Design/methodology/approach

For this purpose, helichrysum oil was encapsulated by ß-cyclodextrin (ß-CD) using the kneading method at three different molar ratios. The products were then applied to 100% cotton fabric through the impregnation method.

Findings

Morphological assessment showed that the inclusion complex had smooth surfaces and spherical shapes. Fourier transform infrared spectroscopy and differential scanning calorimeter analysis results confirmed the formation of the inclusion complex between ß-CD and the active agent at mole ratios of 1:1, 1:2 and 1:3 for helichrysum oil. According to the analyses, it was determined that the highest complexing rate was between 9.72% and 1:2 in capsules containing ß-CD:helichrysum oil and the sizes of particles which is 1:2 are determined to be between 2 and 25 µm. The presence of capsules on the fabrics was determined after 5 washing cycles. Antibacterial activity was evaluated against Staphylococcus aureus and Escherichia coli bacteria. The antibacterial analysis results showed that the inclusion complex provided a reduction of over 96% against both S. aureus and E. coli bacteria, and the fabrics exhibited antibacterial effects even after 5 washing cycles. The major constituents of the oil were decreased after 5 washes, but significant peaks were remained according to the gas chromatography analyses. These results indicate that helichrysum oil can be used for its antibacterial properties, and it has been observed that this activity continues up to 5 washes when transferred to the fabric in the form of an inclusion complex.

Originality/value

Although helichrysum oil is widely used in cosmetics, there is a lack of studies on its application in textiles. Therefore, this study investigated the potential use of helichrysum oil, which has a wide range of applications, in textiles for its antibacterial properties through molecular encapsulation. The use of naturally sourced substances such as helichrysum oil in the textile industry can offer an environmental and sustainable alternative. This study can be considered as a step toward the development of innovative and naturally sourced antibacterial products in the textile industry.

Abstract

Purpose

The study aims to find potential method to enhance the stability and antioxidant activity of vitamins.

Design/methodology/approach

Vitamin E (VE) and β-cyclodextrin (CD) were used to prepare the VE-β-CD inclusion complex via a solution method. The yielded VE-β-CD obtained from optimal experimental conditions was characterized. The mechanism of complex formation and the properties of the complex was investigated by steady-state and time-resolved fluorescence techniques. The antioxidant activity of VE-β-CD was evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH) and compared with pure VE.

Findings

Three experimental factors – reaction temperature (T), molar ratio of VE to β-CD (rm) and inclusion time (t) – were studied for the preparation of VE-β-CD. At experimental conditions of T = 60°C, rm = 1:3 and t = 3 h, a maximum inclusion rate of VE (78.62%) was obtained. The Fourier-transform infrared spectroscopy (FTIR) shows that VE molecule was physically encapsulated by β-CD in the yielded product. Subsequentially, the steady-state fluorescence intensity of VE was found to increase upon encapsulation by β-CD due to the hindrance of fluorescence quenching of VE molecules inside the hydrophobic cavity of β-CD, and an inclusion constant K was determined to equal 3.58 × 103 L/mol from the fluorescence results. The fluorescent observation was confirmed by time-resolved fluorescence experiment as the lifetime of VE increased with an increase in β-CD concentration.

Originality/value

The ability of removing radicals by VE was significantly enhanced after the formation of inclusion complex with β-CD.

Abstract

Purpose

The purpose of this study is to quantify the impact of the variation of microstructural features on macroscopic and microscopic fields. The application of multi-scale methods in the context of constitutive modeling of microheterogeneous materials requires the choice of a representative volume element (RVE) of the considered microstructure, which may be based on some idealized assumptions and/or on experimental observations. In any case, a realistic microstructure within the RVE is either computationally too expensive or not fully accessible by experimental measurement techniques, which introduces some uncertainty regarding the microstructural features.

Design/methodology/approach

In this paper, a systematical variation of microstructural parameters controlling the morphology of an RVE with an idealized microstructure is conducted and the impact on macroscopic quantities of interest as well as microstructural fields and their statistics is investigated. The study is carried out under macroscopically homogeneous deformation states using the direct micro-macro scale transition approach.

Findings

The variation of microstructural parameters, such as inclusion volume fraction, aspect ratio and orientation of the inclusion with respect to the overall loading, influences the macroscopic behavior, especially the micromechanical fields significantly.

Originality/value

The systematic assessment of the impact of microstructural parameters on both macroscopic quantities and statistics of the micromechanical fields allows for a quantitative comparison of different microstructure morphologies and a reliable identification of microstructural parameters that promote failure initialization in microheterogeneous materials.

Abstract

Purpose

The purpose of this study was to provide contemporary scientific knowledge on the functionality of edible lipids, sources, health benefits, and a special emphasis on different encapsulation strategies to enhance their dietary application and boost the market value.

Design/methodology/approach

Novel technologies overcoming these issues are in great demand. Given that, several novel encapsulation techniques have been established aiming at most of the aspects of functional lipids. In addition, these techniques have been designed to enhance the storage stability and controlled release of lipids in food systems.

Findings

Plant and marine oils are one of the richest sources of functional lipids but are attached with limitations. Currently, alternative sources, such as different types of algae and microorganisms are gaining attention in terms of sustainable production systems. Advances in various encapsulation techniques have helped to overcome the dispersibility and stability problems of lipids encapsulation. Refinement in physicochemical interaction, colloidal dispersion and core-shell modules between wall and core matrix protect dietary lipids during processing have been implemented. Liposomes, micro/nanoemulsions and micro/nanocapsules are found most suitable for food application by improving the fatty acid profile, stability and sensorial properties.

Originality/value

Functional lipids offer numerous health benefits (i.e., simple health-promoting properties to complex disease preventive and curative effects). However, these functional lipids are associated with several disadvantages, such as region-specific availability, vulnerability to oxidation depending on the level of unsaturation, degradation/hydrolysis on processing, low bioavailability, confined storage stability, and others.

Abstract

Purpose

The purpose of this paper is to propose a theoretical framework for democratize inclusively through participatory and deliberative apparatus.

Design/methodology/approach

The paper draws on literature from inclusion in deliberation, gender in participation and intersectionality to critically analyze the democratic deepening. By bringing into dialogue with one another “the norm of parity of participation” (Fraser, 2006), “communicative democracy” (Young, 1993) and the “matrix of domination” (Collins, 1990) a response to one of the questions that has been put to European and North American thought in democracy since the 1960s is proposed: how is it possible to democratize inclusively?

Findings

The reproduction of domination through apparatuses for the extension of democracy is both possible and probable. So, to democratize inclusively, it is necessary to bring the theories on vertical and horizontal inclusion into dialogue with each other. With the aim of establishing a dialogue between the two, it is necessary to export complex thought regarding oppression and inequality into the design of deliberative and participatory apparatuses. For that, consider that designing democratization processes based on the fact that the intersectional experience of oppression is not an exception but rather an everyday occurrence allows participatory procedures to be made more inclusive.

Practical implications

This paper proposes a tool designed with a focus on dialogue among the norm of parity of participation, communicative democracy and the matrix of oppression, based on 11 direct questions for the inclusive design of deliberative or participatory procedures. Facilitators, experts and social agents involved in deliberative or participatory processes will be able to use this question-based instrument in their work.

Originality/value

This paper has applied value because it offers a conceptual key to the design of and thought about participatory inclusive processes. The originality of this approach lies in its shift away from partial analyses of horizontal and vertical inclusion. It is of use both to facilitators of participatory processes and educators and researchers concerned with democratization. It offers an instrument for working on reflexivity with regard to inclusion in democratic extension, based on a series of key questions that can be used as a checklist. In comparison with other forms of considering inclusion in democracy, the proposal considered includes complex thought on oppression based on the critique of simple identity, as well as on an intersectional perspective.

Abstract

Purpose

The purpose of this paper is to create a textile material which shows antibacterial activity with resistance to environmental conditions by using volatile active agent inclusion complex and self-assembly method.

Design/methodology/approach

An inclusion complex of carvacrol and β-CD is generated by kneading method and deposited on the cotton fabrics by using a nanofabrication method named as layer-by-layer (LbL) deposition method. Three different concentration of CD and CD:Car aqueous solutions were deposited on cotton fabrics. Attenuated total reflectance Fourier transform infrared spectroscopy (FTIR-ATR), scanning electron microscopy (SEM), antimicrobial efficacy test of fabrics against washing and some physical tests (water vapor permeability, air permeability) were performed on the fabrics before and after the treatment with CD to evaluate the effect of the LbL process on cotton fabric properties.

Findings

The results showed that the coated fabrics with CD/CD:Car multilayer films enhanced the antimicrobial efficacy of cotton fabrics against to Klebsiella pneumonia and Staphylococus aureus bacteria. Air and water vapor permeability properties of the cotton fabric effected after the LbL deposition process sure enough. With SEM and FTIR-ATR analysis the CD:Car complex presence were verified. The durability of antibacterial properties were analyzed after one and ten washing (40°C and 30 min) cycles.

Originality/value

This work provides a novel and simple method for CD and inclusion complex of carvacrol film deposition by self-assembly method on cotton fabrics and their application onto cotton fabrics to gain antibacterial property.

Abstract

Sensory analysis shows that the addition of 0.4 per cent (w/v) of the macrocyclic β‐cyclodextrin (βCD) to goat’s milk improves the flavour and reduces its goaty taste, due to encapsulation of molecules responsible of this flavour. In vitro studies of the inclusion of formed complexes between βCD and short‐chain fatty acids, caprylic (C8...) and capric acid (C10...), were carried out by differential scanning calorimetry (DSC) and proton magnetic resonance (...1HNMR). Complex formation was confirmed by DSC, through the disappearance of the signs due to melting of C10 and C8 after the encapsulation process. The 1H NMR technique shows that C10... is included in the βCD cavity. The results suggest that βCD can encapsulate short‐chain fatty acids, making possible its use for masking of these compounds in goat’s milk and derivatives.

Abstract

There has been a policy for including pupils with severe, profound and multiple learning difficulties in mainstream schools in England since the 1980s. However, effective inclusive education has proved to be very difficult to achieve in practice. Currently, there is a mixed economy of special and mainstream schools offering inclusive education, and we argue that the place of education is less important than the quality of that education. Ideally, pupils with S/PMLD would be educated in their own local communities, alongside their non-disabled peers, but this situation is not yet established in English schools.

Abstract

In contrast to the MDGs' top-down approach, the SDGs took the bottom-up approach of participants, creating an open space for soliciting their aspirations, efforts, creativity, and commitment. Inclusive business (IB), identified as the key means to alleviate poverty and inequality in developing countries, undeniably struggles in this space to find new ways of thinking and management to achieve a suitable balance between serving social needs and achieving business sustainability. However, multinational corporations have not yet made significant achievements, due to a biased orientation of including the poor into their system of developed countries' institutions. From a neutral position, not asking who includes or yields to whom, this research project proposes to use the concept of institutional interconnections and its various analytical factors to examine how diverse partners are interconnected to overcome institutional differences. Differences in interconnections are hypothesized to differentiate IB's socioeconomic effects and poverty alleviation.

Abstract

Purpose

The purpose of this paper is to explore the challenges and opportunities created for inclusion by the election and installation of Donald Trump as the 45th President of the USA.

Design/methodology/approach

The paper uses the author’s personal and professional experience and perspectives to raise and address questions about the limits of inclusion, alternative perspectives on inclusion, and approaches for sustaining attention to and continuing to foster inclusion.

Findings

Although inclusion can be conceptualized in different ways, a nuanced and complex view that incorporates limits to tolerance of behavior that undermines inclusion along with clear rules of engagement, civility, and respect may be most useful and productive.

Originality/value

The paper applies a paradoxical perspective to understanding the implications of a Trump administration for the practice of inclusion, including those particularly relevant for organizational diversity and inclusion practitioners.
