Advances in Engineering Research. Volume 20 begins by analyzing the extraction and separation protocols documented for the saponins from family caryophyllaceae during the period 1967-2014. Analyses of applied extraction and separation protocols of saponins were carried out to determine the most practiced protocols in the study period and to identify eventual trends between protocols, plant material and structural traits of saponins. Next, the authors discuss a 2-D analytical modeling and simulation of Permanent Magnet Induction Generator which is used widely in renewable energy sources such as wind turbines, microhydro plants, and geothermal plants. The aim of the integrated spatial technology is discussed, and identified by the authors as, to combine remote sensing, geographical information systems and life cycle assessment, to ascertain the component or system within the agricultural production cycle, generating the most greenhouse gases. A subsequent chapter deals with modeling of a slip-ring induction motor, and includes two appendixes. The first appendix presents the inversing algorithm of the matrix which consists of four submatrices, and the second presents the algorithm of the inductance inverted matrix determination. The book goes on to discuss the entropy concept as it is applied to uncertainty analysis of systems whose services can be presented by random events. Next, the authors report on a thermo-fluid-dynamic analysis of the internal and external flowfield for a general aviation airplane nacelle, equipped with a small pusher turbine engine, with the purpose of determining the thermal field on the nacelle surface. This compilation attempts to identify the possible performance bottlenecks in the integration solution which deals with the UNIJUI University process of re-enrollment, so that they can be minimized before the solution implementation
