• Most failures of engineering systems result from the gradual and irreversible accumulation of damage: – A process known as Degradation • We examine degradation processes that can be monitored using sensor technology and that result in – Degradation Signals • We focus on – Modeling degradation signals under time-varying environmental conditions. – Computing the distribution of residual life un...

management of the forest resources and related activities has significant effects on the environment. applying the environmental impact assessment (eia) provides a basis for improving forest management plans. however, in the developing countries such as iran, there have been so far no serious endeavors and research to undertake the eia of the various practices affecting the forest resources, de...

abstract the study examines the growth effects of foreign direct investment on environmental quality in nigeria between 1970 and 2013. variables like per capita income, environmental degradation, foreign direct investment, human capital, inflation, trade openness, interest rate, and the interaction term between foreign direct investment and carbon emission were employed in the study. a long run...

Background: This study focused on isolation and identification of a Phenanthrene (Phe) degrader bacterium and optimization of environmental conditions for Phe degradation. Materials and Methods: Enrichment technique was used for isolation and the most effective isolate; named AP was selected based on its Phe biodegradation abilities. The isolate was identified using morphological and biochem...

Rich-poor interactions complicate the search for a stable Environmental Kuznets Curve (an ‘inverted U’ relationship between income per-capita and environmental degradation). We show that aid from richer to poorer countries to support investments in environment, in either of two forms, alters the income-environment relationships that otherwise exist, lowering levels of degradation in the poorer ...

Environmental effects on health are associated with several factors: absent or inadequate environmental health services, such as water supply, sanitation, solid and hazardous waste management and shelter; environmental degradation, such as pollution of air, water and soil, and food contamination; global environmental problems, such as reduction of biodiversity and degradation of ecosystems thro...

The organophosphate pesticide, Ethion, remains a major environmental contaminant in rural Australia and poses a significant threat to environmental and public health. The aerobic degradation of Ethion by mesophilic bacteria isolated from contaminated soils surrounding disused cattle dip sites was investigated. Two isolates, identified as Pseudomonas and Azospirillum species, were capable of bio...

This paper contributes to the ongoing debate on the poverty environment nexus. The interface between poverty and environment has seen an endless debate in Africa. Connection between poverty and environmental degradation with contested concepts. While some scholars place the blame of unsustainable development on the poor, others also ascribe it to the non complex link between economic status and...
