Production and applications of multi-layer 3D fabrics

In this paper, 3D textile structures, their types and applications have been discussed. Woven structures especially multi-layer woven structures are discussed in detail. A simple and quick method to produce 3D textile woven preforms on conventional looms is also given at the end of this paper. 3D textile fabrics give composite structures weight reduction with improved mechanical properties in comparison to traditionally used materials.

A network analysis of IT governance practices : a case study of an IT centralisation project

Information technology governance (ITG) practices rely on both human and nonhuman actors to support the creation of business value in organisations. The role of nonhuman actors in shaping the ITG practices has been given limited attention within the ITG literature. In proposing a model of ITG, this paper highlights the interplay of human and technological artefacts in shaping the ITG practices. Using a case study approach, this paper explores the relationship and interaction between ITG arrangements and IT infrastructure in an IT centralisation project conducted over a number of years in a university. The analysis from this study highlights how problems in aligning actors’ interests and lack of appropriate strategies lead to a failure in establishing a stable ITG network.

Fundamentals and applications of Maldi-Tof MS

MALDI was developed for the ionisation of relatively large polypeptides and proteins but its application has widened to incorporate glycoproteins, oligonucleotides and complex carbohydrates. A great advantage of MALDI TOF MS is that the process of soft-ionisation causes little or no fragmentation of analytes, allowing the molecular ions of analytes to be identified, even within mixtures. MALDI TOF MS analysis is sensitive and very rapid as once the sample has been mixed with a 'matrix' on a MALDI target, a spectrum can be generated within seconds. Hence, the majority of protein and oligonucleotide analysis in the context of high throughput proteomics and genomics is carried out by MALDI TOF mass spectrometry.

Offshoring of IT services : survey of literature and research agenda

Although international outsourcing or offshoring of information technology services by advanced industrialised countries from less developed countries is a relatively new phenomenon, a plethora of research exists on the subject. And, given the multidisciplinary nature of the subject, the literature on offshoring is often disparate and subject to confusion. This paper surveys the developments in the empirical literature on offshoring over the 1992-2007 period and identifies potential areas for future research. The main findings are that while the intensity of research on the subject has increased rapidly over a short period of time, research efforts to date have focussed mostly on offshoring decision and offshoring management particularly from the perspective of the offshorer. Future research opportunities exist in the area of offshoring strategy and performance relationship, the behaviour and performance of offshore service providers particularly within the context of firms from less developed countries competing globally, and the nature of competition among offshore service providers both within and among countries.

The role of human resource practices in developing knowledge and learning capabilities for innovation : a study of IT service providers in India

This paper examines the role of human resource practices in the development of knowledge and learning capabilities for innovation for information technology service providers (ITSP) in India. Developing knowledge and learning capabilities for innovation has been the subject of much attention from industry, governments and researchers. However, the questions surrounding how human resource practices influence the development of knowledge and learning capabilities that lead to organizational innovation remains unclear; particularly for knowledge intensive firms in developing countries. The study draws from the experience of 11 of the largest ITSPs in India and based on in-depth interviews. The findings suggest that while traditional human resource practices are important, senior executives should take a strategic approach in developing human resource practices with knowledge and learning capabilities as central piece for organizational innovation.

Further applications of doppler radar for non-contact respiratory assessment

This paper further investigates the use of Doppler radar for detecting and identifying certain human respiratory characteristics from observed frequency and phase modulations. Specifically, we show how breathing frequencies can be determined from the demodulated signal leading to identifying abnormalities of breathing patterns using signal derivatives, optimal filtering and standard statistical measures. Specifically, we report results on a robust method for distinguishing cessation of the normal breathing cycle. The proposed approach can have potential application in the management of sudden infant death syndrome(SIDS) and sleep apnea.

Fabrication and applications of ultrafine powder from cashmere guard hair

Cashmere guard hair, an industrial animal protein fibre waste material has been very first time converted into ultra-fine powder particles. The work also demonstrates potential of the newly developed particles in high value technical applications such as toxic heavy metal ion separation and surface functionalization of textile fabrics.
