It has often been stated or implied that grazing is an important factor in the land degradation process, a suggestion supported by various research projects, and this study investigated the effect of livestock grazing on stem height, crowncover, production, basal diameter, stem biomass, litter, leaf-stem index (leaf to stem weight) , root diameter and weight and seed production per individual o...

Due to initiatives such as the clean development mechanism (CDM), reducing greenhouse gas emissions for a developing country can offer an important route to attracting investment in a variety of qualifying project areas, including waste management. To date CDM projects have been largely confined to schemes that control emission from landfill, but projects that avoid landfilling are beginning to...

ET ANOTHER SPECIAL ISSUE regarding interand transdisciplinarity may seem annoying to those readers who have followed the discussions about these issues in science policy circles. Interand transdisciplinarity have become buzzwords: their political prestige and ongoing fascination among researchers, notably in the domain of environmental or health issues, seem to rest on the impression that going...

Metaphors, such as the Cathedral and Bazaar, used to describe the organization of FLOSS projects typically place them in sharp contrast to proprietary development by emphasizing FLOSS’s distinctive social and communications structures. But what do we really know about the communication patterns of FLOSS projects? How generalizable are the projects that have been studied? Is there consistency ac...

Though recent advancements in media and computing technologies have fostered greater instructor adoption of student media assignments, few studies have examined the role these projects play in the development of student media production skill sets. This study surveyed 12 first year college students in a postsecondary education class, each responsible for producing a digital story project commun...

This paper summarizes R&D activities and progress at NORAM Engineering and the University of British Columbia (UBC) on preparation and testing of thin palladium-based membranes and their applications. Most of these activities were carried out internally at NORAM, some jointly with UBC and their spin-off company, Membrane Reactor Technology (MRT) through a wide range of projects. Key results out...
