Research ArticleOpen accessIn the keywordsOptimization of the Geometrical Parameters of a Solar Bubble Pump for Absorption-Diffusion Cooling SystemsN. Dammak, B. Chaouachi, S. Gabsi, M. BourouisProblem statement: The objective of this study was to optimize the geometrical parameters of a bubble pump integrated in a solar flat plate collector. Approach: This solar bubble pump was part of an ammonia/water/helium (NH3/H2O/He) absorption-diffusion cooling system. Results: An empirical model was developed on the basis of momentum, mass, material equations and energy balances. The mathematical model was solved … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 5 Nov 2010 · 8,371 accessesView PDF Cite

EditorialOpen accessIn the abstractThe Timeless Contribution of Rootstocks towards Successful Horticultural Farming: From Ancient Times to the Climate Change EraIoannis E. PapadakisGrafting is a horticultural practice by which living vegetative plant organs (root, stem and/or buds) of either the same genotype or, usually, different genotypes belonging to the same species, genus, subfamily and/or family, are tightly connected to each other to form a double-compound plant. In fact, it is a method of asexual (clonal-vegetative) propagation of plants. The basal part of … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 4 · 16 Dec 2016 · 9,521 accessesView PDF Cite

Research ArticleOpen accessIn the abstractDesign and Simulation of an Absorption Diffusion Solar Refrigeration UnitB. Chaouachi, S. GabsiThe purpose of this study was the design and the simulation of an absorption diffusion refrigerator using solar as source of energy, for domestic use. The design holds account about the climatic conditions and the unit cost due to technical constraints imposed by the technology of the various components of the installation such as the solar generator, the condenser, the … …American Journal of Applied Sciences, Vol. 4, Issue 2 · 28 Feb 2007 · 7,677 accessesView PDF Cite
