Advancements in material science have driven the development of the textile industry. Chitosan has inherent advantages, such as biodegradability, nontoxicity, and antibacterial and wound acceleration properties. It has been applied in the textile industry as a coating on fabrics. Nevertheless, research on single-component chitosan fibers is scant. The advantages of single-component chitosan fibers include improved comfort, laundry durability, abrasion resistance, and structural flexibility. To fill the mentioned research gap, this study developed an industrial-manufacturing-based method for testing and analyzing chitosan fibers. This method was demonstrated by studying the physical and biological performance of commercial chitosan fibers. Studying the characteristics of the chitosan fibers revealed the influence of the fiber structure on their performance. Although chitosan fibers with a higher degree of deacetylation had a shorter molecular chain, they exhibited higher strength. Moreover, the molecular weight and deacetylation degree influenced biological performance. Chitosan fibers with higher deacetylation degree chitosan had better antimicroorganism performance on Staphylococcus aureus, Escherichia coli, and Candida albicans; however, no such relationship was observed for the solution form of chitosan. These results imply a difference in antimicroorganism mechanisms between the fiber (solid) form and solution form of chitosan.

The Relationship

Chitosan has been widely studied for use in many areas, such as for its applications in the biomedical, engineering and pharmaceutical fields, as well as in industry, because of its unique properties, including biodegradability, antimicrobial activity, polycationic nature and biocompatibility. Thanks to the rapid development of materials science, chitosan applications are now possible in textiles. However, there are still many limitations of chitosan fibers in terms of their high electrostaticity, poor mechanical properties and high cost, which are obstacles that inhibit potential applications of chitosan fiber in the industry. Generally, in order to achieve the best performance with chitosan and enhance its commercial value, chitosan fibers are usually blended with long cotton fibers in the textile industry. Therefore, based on preliminary experiments and feedback from the industry, this study was carried out to further investigate the relationship between fiber length, fiber interaction and yarn performance. The results of this study would therefore help to reduce the production cost of yarns with the blending parameters used and also expand the utilization and applications beyond medical applications to fashion-based functional wear. The sliver-blending method offers better tensile properties of yarn samples, while the fiber-blending method offers higher uniformity of fiber distribution. This study would help to reduce the production cost of yarns by blending and also to expand the utilization and application not limited to fashion-based functional wear.

Technological advancements in the information technology domain such as cloud computing, industrial internet of things (IIoT), machine to machine (M2M) communication, artificial intelligence (AI), etc. have started to profoundly impact and challenge not only the ISA95 compliant traditional (ISA95-CTS) but also the smart manufacturing systems (SMMS). Our literature survey pinpoints that systems scalability, interoperability, information security, and data quality domains are among those where many challenges occur. Blockchain technology (BCT) is a new breed of technology characterized by decentralized verifiability, transparency, data privacy, integrity, high availability, and data protection properties. Although many researchers leveraged BCT to empower various aspects of industrial manufacturing systems, there is no study dedicated to addressing the challenges impacting the manufacturing systems compliant with the ISA95 standard. Thereby, our study aims to fill the identified research gap systematically. This paper thoroughly analyzes the challenges hampering the ISA95-CTS and SMMS and methodically addresses them with corresponding BCT capabilities. Furthermore, this paper also discusses various aspects, including the weaknesses, of BCT convergence to ISA95-CTS and SMMS.

Heart Of Darkness

The Industrial Revolution was a time of great age throughout the world. It represented major change from 1760 to the period 1820-1840. The movement originated in Great Britain and affected everything from industrial manufacturing processes to the daily life of the average citizen. The main industry at the time was the textile industry. It had the most employees, output value, and invested capital. It was the first to take on new modern production methods. The effects caused by the industrial revolution which has mentioned above, can lead to another impact such as the emergence of where the industry must obtain the availability of raw materials, and the next impact is where the result of the raw material processess by the industry will be marketed. For colonialism itself, generally it is the direct and overall domination of one country by another on the basis of state power being in the hands of a foreign power. Spesifically colonialism has two objectives, they are political domination and the second one is to make possible the exploitation of colonized country. This research aims to find out the colonialisms traits of the characters perform in their respective position, and to reveal the impacts of colonialism on characters.

Biomimetics is an area of research in which the analysis of structures and functions of natural materials provide a source of inspiration for design and processing concepts for novel synthetic materials. Through biomimetics, it may be possible to establish structural control on a continuous length scale, resulting in superior structures able to withstand the requirements placed upon advanced materials. It is well recognized that biological systems efficiently produce complex and hierarchical structures on the molecular, micrometer, and macro scales with unique properties, and with greater structural control than is possible with synthetic materials. The dynamism of these systems allows the collection and transport of constituents; the nucleation, configuration, and growth of new structures by self-assembly; and the repair and replacement of old and damaged components. These materials include all-organic components such as spider webs and insect cuticles (Fig. 1); inorganic-organic composites, such as seashells (Fig. 2) and bones; all-ceramic composites, such as sea urchin teeth, spines, and other skeletal units (Fig. 3); and inorganic ultrafine magnetic and semiconducting particles produced by bacteria and algae, respectively (Fig. 4).

Depth Interviews

This paper proposes a new conceptual framework in understanding the dynamics within the Kurdish and Turkish (KT) owned firms in London by utilising Charles Tilly’s work concerning collective resource mobilisation. Drawing on 60 in-depth interviews with restaurant, off-licence, kebab-shop, coffee-shop, supermarket, wholesaler owners and various community organisations, the paper sheds light upon the questions of why and how the KT communities in London moved into, and are over represented and why Turkish Cypriots are absent in small business ownership. The re-search illustrates that members of the KT communities aligned in their interests to become small business owners after the demise of textile industry in the midst of 1990s in London. The interest alignment in small business ownership required activation of various forms of capital and transposition of social, cultural and economic capital into one another.

The Impact

Purpose- The primary purpose of the study is to determine the impact of organizational justice (OJ) on employee sustainability. Along with that, it also describes how organizational commitment mediates this direct relationship. This study includes all dimensions of OJ which are distributive, procedural and interactional (interpersonal & informational) within the context of a developing country (Pakistan). Design/Methodology- This study has considered employees working in the banking sector of Pakistan. Two hundred ten questionnaires were received back from employees. Regression analysis was used to analyze direct relationships between variables, while smart partial least squares (PLS) were used for mediation analysis. Findings- Results demonstrated that all hypothesis were accepted and it was also confirmed that organizational commitment (OC) mediates the direct relationship between OJ and employee sustainability (ES). Originality/value- Multidimensional construct of organizational justice was tested in this study, in the context of a developing country (Pakistan), to address the research gap.
