Agriculture is an economic activity that contributes significantly to the gross national product of a country, securing at the same time the viability of the rural sector and the social coherence. On the other hand, it can generate an environmental externality, especially concerning water resources...

Organophoshorous pesticides are widely used in agriculture, because most of them are high effective and low persistent. Yet their increased usage has elicited extensive research into pesticide effects on non-target organisms, such as algae. Algae are of vital importance in the primary production of...

The European Water Framework Directive 2000/60 has established a new legislation for sustainable management of water resources and protection of their relevant eco-systems. The primary objective of the Directive which is the achievement of acceptable water quality through the implementation of...

Slurry seal is applied for low-cost paving and surface maintenance. The principal materials used to create slurry seal are aggregates, asphalt emulsion, water and fillers like Portland cement (mainly), lime and other materials. This paper presents the use of alternative fillers instead of expensive...

Life Cycle Analysis (LCA) is a procedure used as an analytical tool for the evaluation of the environmental impact caused by a material, a manufacturing process or product. For an end product, LCA requires both the identification and quantification of materials and energy used in all stages of the...

A pioneer effort is made in this study to carry out an experimental determination of shrinkage characteristics of neem (Azadirachta indica A. Juss) wood on its linear, volumetric, and coefficient values with the hope of ascertaining its utilization potential as timber. Three study locations were...

The present study focuses on the exploitation of sweet sorghum biomass as a source for hydrogen in continuous and batch systems. Sweet sorghum is an annual C4 plant of tropical origin, well-adapted to sub-tropical and temperate regions and highly productive in biomass. Sweet sorghum biomass is rich...

Undoubtedly, sun is the cleanest energy source. Specific systems are needed however for the collection and transformation of solar energy and the manufacturing processes of such systems, as well as the production of the raw materials required, are associated with impacts to the environment. As a...
