An expert system for planning and designing dairy farms in hot climates CIGR Journal
Mohamed Samer; Cairo University, Faculty of Agriculture, Department of Agricultural Engineering; Mohamed Hatem; Hartmut Grimm; Reiner Doluschitz; Thomas Jungbluth.
Eleven simulation models were developed to plan and design several dairy farm facilities.  Subsequently, an electronic spark map (decision tree) was developed for each simulation model, and then the simulation models were integrated into the relevant spark maps.  Afterwards, C# language (C Sharp), which is an object-oriented programming language, was used to develop an expert system via the simulation models and the electronic spark maps.  The developed expert system is able to plan and design several dairy farm facilities, e.g. housing system (corrals system), shade structure and roof material, concrete base, cooling system, milking parlour, forage storage, and manure handling system.  Subsequently, it plans the farmstead layout, and it leads to implement...

Emissions inventory of greenhouse gases and ammonia from livestock housing and manure management CIGR Journal
Mohamed Samer; Cairo University, Faculty of Agriculture, Department of Agricultural Engineering.
An emission inventory is a database on the amount of pollutants released into the atmosphere.  The anthropogenic emissions of air pollutants and greenhouse gases are detrimental to the environment and the ecosystems.  Therefore, reducing emissions is crucial. One key issue is to inventory these emissions, and consequently databases on anthropogenic emissions will be available for making decisions on implementing suitable mitigation strategies.  Such investigations aim at developing national emissions inventory for domestic livestock and to identify possible abatement techniques in order to reduce these emissions.  Therefore, the objectives of this study are to introduce and define the emissions inventories, review the emission inventory guides, introduce...

Towards the implementation of the Green Building concept in agricultural buildings: a literature review CIGR Journal
Mohamed Samer; Cairo University, Faculty of Agriculture, Department of Agricultural Engineering.
The “Green Building” is an interdisciplinary theme, where the green building concept includes a multitude of elements, components and procedures which diverge to several subtopics that intertwined to form the green building concept.  Generally, the green building is considered to be an environmental component, as the green building materials are manufactured from local eco-sources, i.e. environmentally friendly materials, which are then used to make an eco-construction subject to an eco-design that provides a healthy habitat built on the cultural and architectural heritage in construction while ensuring conservation of natural resources.  This ensures disassembling the building components and materials, after a determined building lifetime, to...
