Simulation Of Barley Grain Yield Using Artificial Neural Networks And Multiple Linear Regression Models, Omar Maghawri Ibrahim Hassan
Simulation Of Barley Grain Yield Using Artificial Neural Networks And Multiple Linear Regression Models, Omar Maghawri Ibrahim Hassan
Dr. Omar Maghawri Ibrahim
Developing models for simulation of barley grain yield is important for making early prediction. To simulate barley grain yield, a simple and advanced modeling techniques were used based on a field experiment that was conducted using 40 foreign barley genetic resources from 2007/08 to 2008/09 winter seasons at Kalubia Governorate, Egypt. The barley genotypes were imported from International Center for Agricultural Research in Dry Areas (ICARDA), Syria. Artificial neural network (ANN) and multiple linear regression (MLR) models were developed to simulate barley grain yield. The models were constructed using the first year of field data and validated with the second …
Super Efficient Irrigation With Buried Clay Pots, David A. Bainbridge
Super Efficient Irrigation With Buried Clay Pots, David A. Bainbridge
David A Bainbridge
Buried clay pot irrigation was first described in an agricultural extension bulletin in China more than 2000 years ago. The clay pot provides demand responsive irrigation at very high efficiency. Clay pot irrigation can be 5-10 times more efficient than conventional irrigation. It is being used more widely in Asia, Africa, Latin American and the US.
Pyrite. History, Chemistry, And Metallurgy, Fathi Habashi
Pyrite. History, Chemistry, And Metallurgy, Fathi Habashi
Fathi Habashi
The Book covers the history of pyrite - - how it was a strategic mineral necessary for the production of elemental sulfur needed for making gunpowder for military purposes and for the production of SO2 needed for making sulfuric acid for the chemical industry. Now its presence is a nuisance in tailings ponds. The book also covers the processing of pyrite containing gold, its chemistry and technology, the processing of pyrite cinder for the production of a variety of metals, and its behaviour towards autotrophic microorganisms.
