A series of chemical penetrants are employed to
investigate the chemical characteristics of size bonds in
different sizing systems. The bonding strength has been
proved to be determined by the type of bonding. In rosinalum
size the size bond is an indirect coordinate bond,
which is vulnerable to the attack...
Soil respiration has been identified as one of the largest natural sources of CO₂ to the global carbon cycle. Small alterations in the magnitude of soil respiration can have potentially large effects on concentrations of atmospheric CO₂ , making the rate at which respiration occurs of great scientific interest (Martin...
In an age of increasing complexity, simple answers no longer suffice, but the demand for greater sophistication
is itself at odds with an era of growing specialization. Researchers must thus incorporate information from specialists in
other fields. This trend in interdisciplinary research contains hidden challenges, however, including a necessary familiarity...
In developing countries the framework for institutional engagement in small-scale fishing communities needs to consider the regional, social, economic and environmental complexities of informal resource-based economies. The combination of socio-economic trajectory of artisanal fisherfolks, their relationship with the environment, the economic pressures and the public policy framework, which often regarded...
Fisheries management is more of human management than fish management. This is evidenced by the many fishing regulation that are developed world-wide and imposed on the fishers who harvest the fish resources. A number of fisheries management regimes have been devised and implemented to sustainably manage the world fisheries but...
In recent years, considerable attention has been given to the effects of removing trade restrictions on natural resource utilization and on poverty, especially in developing countries. Our paper adds to the growing body of conceptual work to show conditions under which a developing country that, in isolation, is unable to...
Marine ecosystems are generally more extensive and complex than terrestrial ecosystems. Our understanding of the ecological relationships and biological processes within marine ecosystems is rudimentary but improving. In addition, our appreciation of the range of goods and services available from the marine environment and demand for competing economic uses of...
In 2002, the offshore and coastal fisheries only account for 19.9% and 7.3%, respectively, of the total landing value. Since 1978, the offshore harvests follows a downward trend, but the number of fishing vessels, the total vessel tonnage, and the total horsepower of vessels follow an steady increasing trend until...
The International Food Policy Research Institute (IFPRI), the World Fish Center (ICLARM), and the Food and Agriculture Organization (FAO), are collaborating to incorporate fish into IMPACT, a global model of food supply and demand that estimates market-clearing prices for 28 commodities in 36 regions. Results of the projections to 2020...
