Changes in proximate composition, colour and textural characteristics of ozone-processed shrimp as affected by combined effects of increasing ozone exposures and iced storage were investigated and for the first time. Whilst proximate composition comprised of fat, moisture, and protein contents and colour comprised of L*, a*, b* and metric chroma (C), the texture comprised of adhesiveness, fract...

In this paper we discuss the usage of Collaborative Virtual Environments (CVE) in educational settings. In particular we discuss the role that these systems can play in supporting learning communities. The focus of the paper is on the representation of space that underlies these systems. We present and compare different spatial metaphors presented in the literature and analyze how they support ...

Presence in Collaborative Virtual Environments (CVEs) can be classified into personal presence and co-presence. Personal presence is having a feeling of “being there” in the CVE yourself. Co-presence is having a feeling that one is in the same place as the other participants, and that one is collaborating with real people. In this paper we describe an experiment used to investigate the effects ...

This study investigated 2-wheeler exposures to CO and PM10 along six standardized arterial main road stretches in Bangalore city in India during morning peak (9:00-11:00) and afternoon non-peak hours (13:00-15:00) using personal samplers. Background levels on a local street carrying no traffic and away from main roads were also monitored to determine the actual contributions of vehicular traffi...

The feasibility of predicting the fracture behavior of surface cracks from shallow cracked bend specimens was investigated. The material studied was a high-strength steel stress relief embrittled to various levels of Charpy-V notch impact toughness. Material toughness was quantified in terms of the J-intergral at total specimen failure (-/„,,), using both deeply notched and shallow-notched bend...

Analysis of banks’ r isk exposures is important both for management within banks and for bank supervisors. Two major sources of risk for banks are credit risk (the risk that loans will not be repaid) and market risk (the risk of losses arising from adverse movements in market prices). This article focuses on the analysis and management of market risk, an area that has received increasing attent...

We argue that a conceptual framework is required to support the practical evaluation of collaborative virtual environments. We propose such a framework based on an extended, three level concept of affordance. The application of the framework is illustrated by way of a case study. We conclude with some reflection on the framework’s effectiveness and identify areas where further tools or conceptu...
