impact of biobased industrial products in the twenty-first century. The priorities for research and commercialization were described in terms of agriculture expanding into health, energy, chemicals and materials. Agriculture is now armed with new biotechnology and bioprocessing tools, and is going back to reclaim the markets it lost to the petrochemical industry after the 1930s. This paper will...
In recent decades, the use of nitrogen fertilizers has increased irrespective of their effects on soil properties, agricultural products and, particularly, on environmental pollution. Nitrate easily leaches from soils into groundwater. The objective of this study was to determine temporal and spatial nitrate concentrations in groundwater in agricultural, industrial and urban regions in some par...
1.2 The title of the session is “Industrial Archaeology”; however, given that industry, technology and trade have been considered in detail in the other period seminars for the Regional Research Frameworks process this paper will consider the archaeology of the industrial period. The broad period band for the industrial period is 1750 to the present day. The major emphasis is upon the process o...
It is being argued that there will exist high reliance upon agriculture lands and resources as a provider of food for population in coming decades.

However, the utilization of soil, water, forest and pasture are geared toward extensive an...
abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...
During the last decade, arrays of exploratory experiments conducted to gauge the solid impact of nanotechnology have comparatively proved its efficiency. Nanoparticles (Nps) are solid particles with dimensions between 1 to 100 nm. At present, Copper (Cu) nanoparticles find wide applications in agricultural, industrial engineering and technological fields. In agriculture much effort has been mad...
objective(s): particularly in developing countries, selenium and/or iodine deficiencies are encountered and use of pesticides in agriculture are not well-controlled. fenvalerate is a pyrethroid insectide used in agriculture and has applications against a wide range of pests. this study was designed to evaluate the effects of fenvalerate on hepatic and cerebral xenobiotic metabolizing enzyme act...
India is an agriculture based developing country. Information dissemination to the knowledge intensive agriculture sector is upgraded by mobile-enabled information services and rapid growth of mobile telephony. It bridge the gap between the availability of agricultural input and delivery of agricultural outputs and agriculture infrastructure. Mobile computing, cloud computing, machine learning ...
Conservation agriculture (CA) integrates ecological management with scientific agricultural production. CA promotes minimal disturbance of the soil by tillage (zero tillage), balanced application of chemical inputs (only as required for improved soil quality and healthy crop and animal production), and careful management of residues and wastes. CA Promotes application of fertilizers, pesticides...
