A detailed study of a soil in every country is of a paramount importance, because it determines an entire economic strategy. The mineralogical properties of soils have been studied in the world for more than 100 years by various characterization techniques, X-ray diffraction being the most prominent. The main difficulty in most of employed techniques is the dominance of the majority phases in the response or the measured signal from the sample that becloud minority phases preventing their identification. The application of methods of phases'separation would provide the possibility to discern minority phases in soils. This work presents a phase separation method that employs a combination of two phenomena based on principles of fluid dynamics: flotation and sedimentation. Different characterization methods were used to analyse the produced soil samples. The methodology employed for separation of phases allowed the complete separation of clay phase from heavier mineral phases. This result makes it possible to discern minority mineral phases of soils that are difficult to detect. A more accurate determination of the mineralogical composition of a soil becomes feasible. |

This paper describes the core of an object-oriented simulation framework (SF), implemented in C++, to support hierarchical dynamic systems simulators development. The simulation framework (SF) presented herein arose from the need for a tool to facilitate and standardize the development of process-based simulation models in research projects at Embrapa (Brazilian Agricultural Research Corporation). This SF targeted modularity and simplicity of code to facilitate model development by multidisciplinary research teams and implementation by high turnover groups of student trainees. Model components, typically developed by teams of experts in specific processes, can be developed independently and later connected, sequentially or aggregated in a hierarchical way. The SF allows compiling simulators as libraries and provides a general interface to allow simulations to be carried out by client applications, e.g. graphical user interfaces, databases, statistical or mathematical packages. In contrast to other existing frameworks, this SF does not store the trajectories of the variables but allows the client application to get the values of the outputs along the simulation through the use of callbacks. The client application can store the variables trajectories in the most convenient way for its specific purpose. The SF supports continuous, discrete-event and hybrid simulations. An example application is provided. |
