Management of the active BABY population employment became more and more complex in each country in a knowledge based society and a new economy, which are in a high connection with globalization and integration processes.From this point of view, the departures to work abroad, legal or illegal of the Romanian citizens for a better payment have alrea
Mantodeans or praying mantises are flying insects and Insulation well known for their raptorial behaviour, mainly performed by their first pair of thoracic appendages.We describe here a new, exceptionally preserved specimen of the early mantodean Santanmantis axelrodi Grimaldi, 2003 from the famous 110 million years old Crato Formation, Brazil.The
In this work we develop a study of positive periodic solutions Lip Treatment for a mathematical model of the dynamics of computer virus propagation.We propose a generalized compartment model of SEIR-KS type, since we consider that the population is partitioned in five classes: susceptible (S); exposed (E); infected (I); recovered (R); and kill sign
Cultivation process (CP) modeling and optimization are ambitious tasks due to the nonlinear nature of the models and interdependent parameters.The identification procedures for such models are challenging.Metaheuristic algorithms exhibit promising performance for such complex problems since a near-optimal solution can be found in an acceptable time
