The ubiquity and wide deployment of wireless local area networks (WLAN) have increased the inherent risk of interference. Numerous studies have shown that power control is an efficient alternative to deal with interference and an outstanding framework for modeling scenarios in which user equipments perform power control is game theory. However, the research in this field has focused on the theoretical analysis and system-level simulations given the complexity of implementing power control in a real environment. This paper shows the implementation of a power control algorithm for WLAN based on game theory (GT), specifically, the IEEE 802.11.a standard using software defined radio (SDR) platforms and reconfigurable hardware. The results show that the algorithm significantly increases the energy savings and energy efficiency of the stations (STA) and decreases the interference. The interference reduction improves the overall network performance, decreasing the FER, and increasing the throughput. [ABSTRACT FROM AUTHOR]

This paper describes the design and implementation of a teaching strategy for teaching the phenomena of light's interference and diffraction, aimed at high school students from a public institution in Bogotá, Colombia. The strategy developed is composed of six activities using the Active Learning Methodology (ALM), which aims to promote the construction of concepts through the development of simple experimental practices with low cost material and easy local achievement. This strategy improved the understanding of said phenomena, which was evidenced by analyzing the performance of the same in the diagnosis and final tests, using as a measuring instrument normalized gain Hake, this showed that 46% of students presented a gain of high learning, 50% showed average 4% gain and low gain obtained.

The present paper is a proposal of classification of transfer errors from a pedagogical point of view. It is also a proposal to work with transfer errors, since, thanks to the use of the monitor model, you can activate the autocorrection so that these errors can be easily avoided.

Validation of viral clearence capacity in biological manufacturing process is neces sary to offer a final product with an appropiated accurancy level and in this procedure should be ajusted the conditions that allow the precision of the study. The aim of this paper was to stablish the procedure of processing samples and to demostrate the feasibility of using viral models in validation of SURFACEN® production process. The samples of the production steps were diluted 1:5 and 1:10 in buffer solution. Serial dilution were made and it was selected the dilution which citotoxicity was moderate. Five viral models were diluted 1:10 in pulmonary washes in order to determine the interference. It was taken an initial sample and a second one after one hour. None interference was consider when the difference between viral tittles was less than 2 log. Morphology of cells showed from light to high changes in 1:5 dilution, whereas in 1:10 dilution variation was minimun to moderate during the citotoxicity study. The last one dilution was selected to process the samples. The viral models tittles in presence of pulmonary washes decrease lower than 2 log, without significant differences. These results allowed to stablish the methodology for processing samples and showed the feasibility of viral models in the validation of viral clearence capacity of the SURFACEN® production process.

Combined vaccines have a higher level of acceptance in the population because fewer immunisations are required for protection against infectious diseases. Nevertheless, new challenges have appeared due to the report of some interference among the antigens included in such vaccines. The aim of this paper was to evaluate whole-cell Pertussis (wP) interference in potency tests with other antigens like tetanus, Haemophilus influenzae type b (Hib) and hepatitis B. For that purpose, we evaluated combined vaccines and compared them with the respective monovalent vaccines. Likewise, we prepared experimental formulations with different antigen combinations to evaluate the extent and nature of the interference caused by wP. We obtained a significant increase of the tetanus and Hib biological activities when both antigens are combined with wP, although it depended on the animal model and the experimental design used. On the other hand, wP decreased both the in vivo and in vitro potency of HB in a non-significant way. [ABSTRACT FROM AUTHOR]
