Abstract
Purpose
In this research project, electrical conductive yarns were knitted together with 100 per cent cotton yarns to create knitted fabrics that would be used as electromagnetic (EM) shielding materials. The paper aims to discuss these issues.
Design/methodology/approach
1×1 plain fabrics knitted on double-bed hand knitting machines of five and seven gauges. Several strands of the cotton yarns were used together in order to knit samples with good handling properties. The electrical conductive yarn has six plies and each ply has 29 filaments with Naño-coating of silver and having an electrical resistance of 4 Ohms per 100 mm and a count of 96 Tex. The knitted fabrics have similar texture but vary in term of specific weight, fabric density, loop length, Tex, tightness factor, thickness and electrical conductivity. These variations affected the properties of the fabrics, determining factors of a good shielding or not. A special designed Faraday cage was built to measure the EMSE of each knitted fabrics. The EM waves were sent through the signal generator at different frequencies as from 400 to 1,100 MHz and with three different power inputs of 10, 20 and 30 dBm. EMSE measurements were also carried out after the knitted samples were rotated clockwise.
Findings
Good EMSE shielding results were achieved with the knitted samples, however in this study it was found that different knitted fabrics shielded better at specific frequencies and power inputs.
Practical implications
Knitted fabrics can be used to develop comfortable garments that can be used to shield EM waves and protect the wearer.
Originality/value
The choice of using the conductive yarns is exclusive. In addition the EMSE were measured with fabrics knitted in the same structure but on different knitting machine gauge. Three different power inputs were considered and EMSE measurements were taken using frequencies as from 400 to 1,100 MHz. A new method for measuring the electrical resistance on the knitted fabrics and the method used for measuring the EMSE for each knitted fabric were considered.

Abstract
This chapter provides the multifaceted ways of how the institution has been supporting teaching and learning (T&L) with the use of technology and how it is equipping the younger generation with the skills required to face a changing job market. The prevailing status of use of Fourth Industrial Revolution (4th IR) in T&L was evaluated through: (i) outcomes of a survey approved by the institution undertaken with academics and students for its external audit in 2018; (ii) the continuous support being provided by the Center for Lifelong Learning for fully online programs through the Moodle Platform; and (iii) use of Google Classroom, smartphones, and tablets in faculty-based teaching by the information and communication technologies (ICT) department. This study aimed to identify gaps with a view to enhance the quality of blended/online learning. Findings of the survey reveal that 59.2% of academics who responded were satisfied with the applications of ICT in their teaching, with 42% indicating that there is a need for improvement. Similarly, 55.1% of students who responded indicated that they were satisfied with the use of technology in the classroom. The case studies support the surveys and provide indications of ongoing advancement in the use of ICT following the external audit. The advent of the pandemic has further accelerated our plans in the digital transformation process, leaving us with no choice but to innovate with the use of ICT in the classroom.

Abstract
The role of information and communication technology (ICT) in education is increasingly gaining importance in institutions of higher education. Operationally, ICT has helped to cut costs and speed up transactions by streamlining and automating processes. Pedagogically, it has enabled online, hybrid, and technology enhanced learning as well as a host of other capabilities, from learning management systems to student information system, and from student affairs to academic affairs. ICT is now embedded in every aspect of university life. The role of ICT is found to increase the value of classroom delivery, it has helped in the growth of research, expanding horizons for students mainly with limited accessibility to education and it has created an overall positive impact in the teaching–learning environment in general. There are always two sides to the coin and in this case inaccessibility, economic disparity, and ineffective implementation of ICT has also created impediments for effectively adopting and diffusing integration of ICT into pedagogy. This volume is a collection of interventions and collaborative practices across the world that showcases the multifaceted ways of how various institutions have been engaged in supporting teaching and learning with the use of technology and how it is equipping our future generation with the skills required to face a changing job market.
