Abstract The aim of this work is to set up the methodologies of experimentation on industrial shelves in order to study their mechanical behaviors. This derives from the necessity to support the planning with realistic data, that furnish more certain and suitable safety coefficients. We have concentrated the experimentation on a particular typology of shelf: the Door-Pallet. The examined modular elements are constituted by different typologies of columns and different beams (shape and dimensions) but not for technologies of realization: elements obtained by different thickness metallic plates subjected to cold workmanships like cutting, perforation, folding and welding. The column/crossbeam connection has been made by means a particular system of hookup.
Keywords buckling, crippling, steel sheets, numerical modelling, stiffness

Abstract In the coming decades accelerating population growth, surface water pollution, and climate change together may produce a drastic decline in fresh water supply. Keeping the above factors in view, the quantification and conservation of surface water resource is needed for ensuring livelihood. The study area chosen is Kabini command area spread in Mysore and Chamrajnagar districts, Karnataka. The objective of the study is to assess the capability of land for agriculture in order to make the land more profitable and also to determine the best suitable areas for the crops viz,. Paddy, Sugarcane and Cereals. For LCC, slope, soil depth, texture and land use/ land cover conditions are assessed through remote sensing and GIS environment. The analysis reveals that 5 classes I, II, III, IV and V are present in the command area. The evaluation of land in terms of the suitability classes is based on the method as described in FAO guideline for land evaluation for rainfed agriculture. A land unit resulting from the overlay process of the selected theme layers has unique information of land qualities for which the suitability is based on. The selected theme layers includes soil texture, soil depth, land use/ land cover, rainfall, slope, aspect, pH, erosion, drainage density and temperature which are overlaiyed in ArcGIS using Analytical Heirchical Process (AHP). It reveals that 4 classes has been identified as highly suitable (S1), moderately suitable (S2), less suitable (S3) and not suitable (N).
Keywords Agriculture, AHP, GIS, land capability classification, land suitability, RS.

Abstract The accelerated urbanization process in Morocco has steadily increased the amount of energy consumed in buildings over the last years. Thermal insulation is one of the effective ways to reduce the energy demand and to improve the energy efficiency. Therefore, in the present paper, optimum insulation thickness of three different insulation materials is investigated for six locations in Morocco and four heating energy sources. Likewise, the potential of abatement of fuel consumption and emissions achieved by introducing optimal thickness is analyzed. The overall results show that the optimum thickness is in the range of 0.013-0.077 m, the energy cost saving in the range of 1.77-38.70$/m² and the payback period in the range of 6.06-13.67 years, depending on the city, the energy source and the insulation material. Furthermore, it was demonstrated that applying optimized thickness for proper insulation material leads to a significant mitigation in fuel consumption and greenhouse gas emissions.
Keywords Building, Morocco, Optimum insulation thickness, Energy cost saving, Fuel consumption and emissions.

Title Increased Absorption Capacity of Organokaolin Adsorbents in Absorb Metals Using Microwave Technology

Abstract This research is about the absorption of iron and magnesium metal ions in water using many kaolin adsorbents in nature. Kaolin absorption is still very low so it is necessary to modify kaolin using acyl sulfonate (ABS) surfactant which is an organic compound. The aim is to increase the absorption capacity of kaolin in absorbing metal ions contained in water using modified kaolin to get effective absorption results in absorbing metal ions, especially iron, this research was carried out by varying microwave irradiation time 5, 15, 30, 50 and 80 minutes using surfactant kaolin modification and without surfactant modification, the waste used was artificial waste with an initial concentration of 100 mg / l. The samples were analyzed using Atomic Absortion Spectrophotometers (AAS), while the characteristics used were Fourier Transform Infrared Sectroscopy (FTIR) and Scaning Electron Microscope (SEM). Kaolin modification with microwave use in the adsorption process results in a decrease in artificial Fe waste at 3 minutes irradiation time on modification of efficiency reduction of 72% and Mg waste at 30 minutes decreased by 61%.
Keywords adsorption, adsorbent, metal ion, kaolin, microwave, surfactant
