International Journal of Polymer Science, Volume 2018, Issue 1, 2018., 2018 Essential oils (EO) are complex mixtures of biosynthesized chemicals basically by plants, which provide them their characteristic aroma. Many have biologically recognized activities as antioxidants and anti‐inflammatory among others, and many of them are employed as cosmetic actives. Very often, these properties are not fully exploited because of their

Generation and Control of Basic Geometric Trajectories for a Robot Manipulator Using CompactRIO®
Journal of Robotics, Volume 2017, Issue 1, 2017., 2017 The utility of a robot manipulator focuses on the ability to locate its end effector in a position with a determined orientation following a specified trajectory. For this, algorithms were used in order to generate and control the movements joints of robot in a synchronized way.

Asymptotic behavior of solutions of the damped Boussinesq equation in two space dimensions
International Journal of Mathematics and Mathematical Sciences, Volume 22, Issue 1, Page 131-145, 1999., 1999 The Cauchy problem for the damped Boussinesq equation with small initial data is considered in two space dimensions. Existence and uniqueness of its classical solution is proved and the solution is constructed in the form of a series. The major term of its long‐time asymptotics is calculated explicitly and a uniform in space estimate of the residual ...
