5. Estrategia para la optimización de un compuesto de caucho con aceite de soja utilizando diseños de experimentos
ABSTRACT When a rubber component is made, is necessary to start from a “rubber compound” which may be composed of one or more polymers and various additives or fillers. The development of an elastomer mixture to produce a compound with a specific end-use is complicated in the field of rubber technology. Therefore, the successful development of a compound

6. Manufacturing and Characterization of Jute/PP Thermoplastic Commingled Composite
The commingled technology is a promising technique for the manufacture of composites reinforced with natural fibers. This study presents the development, processing and basic characterization of a long fiber Jute/Polypropylene (Jute/PP) commingled composite. The Jute/PP fabric was produced in a handloom and the composite was consolidated by compression moldi

7. Production and characterization of nanocapsules encapsulated linalool by ionic gelation method using chitosan as wall material
Abstract Linalool has been extensively applied in various fields, such as flavoring agent, perfumes, cosmetics and medical science. However, linalool is unstable, volatile and readily oxidizable. A sensitive substance can be encapsulated in a capsule, so encapsulation technology can solve these problems. In this paper, linalool-loaded nanocapsules (Lin-nanoc

8. Design of high gain and wide band EBG resonator antenna with dual layers of same dielectric superstrate at X-bands
Abstract A wide band EBG resonator antenna with two layer of dielectric superstrates of the same material is design which is operating in X band. The EBG superstrates act as Partially Reflective Surfaces (PRS) having positive reflection phase curve which are suspended above a double sided dipole patch antenna fed by a coaxial cable pass through ground plane.

11. Synthesis and characterization of Ni-Mo filler brazing alloy for Mo-W joining for microwave tube technology
A brazing process based on Ni-Mo alloy was developed to join porous tungsten cathode bottom and dense molybdenum cathode body for microwave tubes manufacture. The Ni-Mo alloy was obtained by mixing and milling powders in the eutectic composition, and applied on the surface of the components. The brazing was made at 1400 °C by using induction heating in hydr
