Looks at the eighth published year of the ITCRR and the research, from far and near, involved in this. Muses on the fact that, though all the usual processes are to the fore, the downside part of the industry is garment making which is the least developed side. Posits that the manufacture of clothing needs to become more technologically advanced as does retailing. Closes by emphasising support for the community in all its efforts.

Discusses the 6th ITCRR, its breadth of textile and clothing research activity, plus the encouragement given to workers in this field and its related areas. States that, within the newer research areas under the microscope of the community involved, technical textiles focuses on new, ‘smart’ garments and the initiatives in this field in both the UK and the international community at large. Covers this subject at length.

The aim of the paper is to apply a numerical dosimetry procedure to a biological tissue with an embedded discrete vascularisation in order to evaluate the temperature increase produced by radio‐frequency (RF) exposure.

The blood temperature inside thin vessels is analysed by a 1D finite difference procedure to solve the convection‐dominated heat problem. The tissue temperature inside the remaining 3D domain governed by the heat diffusion equation is calculated by the finite element method. Then, the two separate numerical methods are coupled by an iterative time domain procedure.

The main advantage of the proposed hybrid method is found to be the considerable reduction of the number of unknowns respect to other traditional numerical techniques.

In this paper, only the numerical model of the new hybrid procedure has been proposed. In future work realistic biological regions will be examined and the proposed model will be improved by considering the artery/vein coupled structure.

The originality of the proposed method regards the solution of the bio‐heat equation by means of a new hybrid finite element/finite difference procedure. This procedure is applied inside a vascularized region considering a discrete blood vessel structure.

The preponderance of studies that rely on self-report for both independent (e.g. stressors) and dependent (e.g. well-being) variables is often deplored, as it creates problems of common method variance, which may lead to inflated, or even spurious, correlations and predictions. It is sometimes suggested that alternative measures should yield more “objective” information on the phenomena under investigation. We discuss this issue with regard to: (a) observational measures of working conditions; (b) physiological measures of strain; and (c) event-based “self-observation” on a micro-level. We argue that these methods are not necessarily “objective.” Like self-report, they are influenced by a plethora of factors; and measurement artifacts can easily be produced. All this can make their interpretation quite difficult, and the conclusion that lack of convergence with self-report automatically invalidates self-report is not necessarily warranted. Especially with regard to physiological measures, one has to keep in mind that they refer to a different response level that follows its own laws and is only loosely coupled with psychological responses. Therefore, replacement is not a promising way to get more reliable estimates of stressor-strain relationships. We argue instead that each method contains both substantive and error variance, and that a combination of various methods seems more auspicious. After discussing advantages and pitfalls of observational, physiological, and self-observational measures, respectively, we report empirical examples from our own research on each of these methods, which are meant to illustrate both the advantages and the problems associated with them. They strengthen the overall conclusion that there is no “substitute” for self-report (which often is necessary to be able to interpret data from other methods, most notably physiological ones). They also illustrate that collecting such data is quite cumbersome, and that a number of conditions have to be carefully considered before using them, and we report some problems we encountered in this research. Altogether, we conclude that self-report measures, if carefully constructed, are better than their reputation, but that the optimal way is to complement them with other measures.

This paper aims to consider the heat transportation together with irreversibility analysis for the flow of couple stress hybrid nanofluid past over a stretching surface. The innovative characteristics of this paper include electro-magnetohydrodynamic (EMHD) term, viscous dissipation, Joule heating and heat absorption\omission. The hybrid nanofluid is prepared due to the suspension of the solid nanoparticles of the single wall and multi-wall carbon nanotubes (SWCNTs and MWCNTs) in the blood for the testing purpose of heat transfer and drug deliveries. The experimental value of the Prandtl number used for the blood is 21 from the available literature and very large as compared to the Prandtl number of the other base fluids. Appropriate transformations are incorporated to convert the modeled partial differential equations into the nonlinear ordinary differential equations. The homotopy analysis method (HAM) is used to obtain the solution. The explanation for velocity, energy and entropy are exposed under the influence of various parameters such as E, M, k, Q, S and Ec. The numerical values are calculated and summarized for dimensionless Cf and Nu.

The explanation for velocity, energy and entropy are exposed and the flow against various influential factors is discussed graphically. The numerical values are calculated and summarized for dimensionless In addition, the current study is compared for various values of to that published literature and an impressive agreement in terms of finding is reported. It has also been noticed that the and factors retards the hybrid nanofluid flow, while the temperature of fluid becomes upsurges by the rise in these factors.

This is examined while evaluating the previously discussed publications that study on EMHD aspects of magnetized Casson type hybrid nanofluid via entropy generation research is innovative but also acknowledging that the couple stress model challenged bilaterally on stretching surface has not yet been studied. So, there is an ongoing attempt to bridge such a space.

Performing physical activity and sports generates a wide range of physiological alterations and adaptations. Several different textiles can help to improve some of these processes. The purpose of this paper is to review the literature addressing the physiological effects of textiles with bioceramic materials in physical activity and sports.

A search was carried out in the scientific literature available in Web of Science, Scopus, PubMed and SportDiscus. In total, 295 records were identified through the database search; after removing duplicates and reading the title and abstract, only 4 articles fulfilled the inclusion criteria. These were thus included in the qualitative synthesis.

The use of bioceramic garments affects thermoregulation, helps to reduce body temperature during physical activity, provide better sweat evacuation and lower bacterial growth, improves performance, and facilitates recovery after exercise.

There are few scientific studies that analyse the use of bioceramic garments; however, it is difficult to demonstrate the validity of this type of garment. Therefore, future studies are necessary to analyse their suitability in this area.

For many developing country citizens, traditional herbal medicines offer affordable alternatives to expensive orthodox options. Consumers learn about them from different sources including the packaging, which by regulatory demands must provide certain information. In countries such as Ghana, many herbal medicine brands combine packaging information with radio presenter mentions (PMs) as the primary modes of advertising. The purpose of this study is to compare radio PMs of herbal medicines to their packaging information to see how consistent they are in providing credible information to consumers.

The study uses comparative qualitative content analysis to compare information about disease indications, directions for use and warnings/cautions as provided on the packaging and in PMs to gauge the extent of their congruence.

Findings show that there are substantial cross-channel message differences. These differences range from under-representation to sometimes, blatant misinformation, suggesting the possibility that audiences will have difficulty relying on them for decisions.

This study only addressed issues with the manifest content of herbal drugs’ packaging and PMs. It does not include any interviews with consumers to gauge the extent of their consciousness of the lapses identified, and how they are affected by such. In addition, the study sample is context-specific. Ghana presents an interesting setting for the study but it is none-the-less only one country, denying us the power to generalize the findings.

The study points to a need to pay closer attention to message salience and consistency where multiple channels are used in promoting herbal medicinal products. Due to their historically traditional context of consumption in many developing countries, regulatory frameworks on herbal medicine markets are often lax. This study calls attention to a need for better policing on how herbal medicinal products promote themselves, particularly where they use multiple media channels that introduce variations into their messages.

The study calls attention to the credibility of cross-channel messages in supporting consumers of medicinal products. Secondly, because of the predominance of the normative view in medical advertising, channels such as PMs that accommodate message variation and improvisation have eluded critical analysis. By its focus on the presenter mention advertising format, the study also draws attention of health communication scholars to begin to include emerging modes of medical advertising in their analysis.

This paper presents an evaluation of a commercially available intelligent search agent for the Internet. Search robots and search engines can be of great help in finding information on the Internet, but their different features and sometimes their unfriendly interfaces can be confusing. Some expect that intelligent search agents could solve these problems. But most of these applications are not yet on the market, and the few that are: do they really perform? One of the few commercially available search agents is Autonomy, from Autonomy Corporation. Its concept is promising to professional users: the natural language processing of the query, the take‐over of repetitive jobs, an integrated interface for searching and managing information, and the sharing of knowledge with other users. The test in this article, however, reveals that the product is not yet ready to challenge the Internet search indexes which, in the test cases, perform better than Autonomy does with regard to recall and precision of information retrieval. Moreover, Autonomy does not give enough feedback to control the search action.
