Despite the general understanding that land degradation is a threat to agricultural productivity, very few studies have been done to quantify the extent, rate and process of soil fertility depletion under different land uses and management practices in the country (Elias 2002).
Due to human activities to a greater extent and natural processes to some extent, a large number of organic chemical substances such as petroleum hydrocarbons, halogenated and nitroaromatic compounds, phthalate esters, solvents and pesticides pollute the soil and aquatic environments.
The research results also indicate that the GPR method is effective, nondestructive, and convenient for evaluating the spatiotemporal extent and development processes of the freeze thaw states of pipeline foundation soils and the underlying permafrost.
Autophagy and apoptosis are mutually inhibitory to some extent, and both processes may be competing in a stressed cell (Mauiri et al. 2007).
Glacial erosion has created distinctive types of landscapes reflecting the extent, duration, and processes of the parent glaciers.
According to this model we study to which extent the structure and process of care and patient factors affect the quality of life during the last days of life and quality of dying in the hospital [ 45, 47].
Following knowledge accumulation during commercial production, PAT may be removed or reduced under certain circumstances based on consideration of extent of product and process understanding, nature and role of the PAT, complexity of the product and process, availability, and life cycle cost of instrumentation.
In this study, we grouped beneficiaries based on spatial extent and bio-economic process to be consistent with the beneficiaries' concept in the System of National Accounts SNAA).
The action research approach adopted for the study aimed to bring about change as well as produce information about the nature, extent and costs of process and impact [ 12].
This paper attempts to fill this gap by presenting a conceptual framework and method for determining the extent of service product and process attribute standardization versus customization in these settings.
The present paper addresses how well we have been able to predict complex changes during our initial analysis, and how and to what extent the process to elicit and assess the impact of such changes might be improved.
