38. FD MAC Protocol Design for Co-Existing WLANs in 5G Cellular Networks
Abstract In this paper, we design full-duplex (FD) medium access control (MAC) protocol for co-existing wireless local area networks (WLANs) in 5G cellular networks (WCFD-MAC). Our design considers some significant features of 5G networks, exceptionally, beamforming and FD capabilities at both, the base station and user equipment. FD communications may gener

39. Comparison Between Three- and Four-coil Wireless Power Transfer Systems with Resonant Coils
Abstract In this paper, it is demonstrated that the efficiency and ability to transfer power to the load in three-coil wireless power transfer (WPT) systems are always higher than in equivalent four-coil ones. On the other hand, it is shown that there are features attainable in four-coil WPT system that are not in three-coil ones. For instance, in a four-coi

41. Identification of Two Additional Behaviorally Active Gland Constituents of Female Diatraea saccharalis (Fabricius) (Lepidoptera: Crambidae)
The sugarcane borer, Diatraea saccharalis (Fabricius), is the major pest insect attacking sugarcane crops in Brazil. Population control by insecticide treatment is not efficient due to simultaneous presence of all developmental stages of the insect throughout the year, and alternative control methods are needed. Two female-produced sex pheromone components,

42. Risk perception related to food
Abstract There is no human activity that is risk free, including those most trivial and essential for survival, such as eating. Various factors impact the risk perception of a population, such as whether the risk is voluntary, known, brings some benefits or whether the information about the risk is provided by sources seen as trusted. Furthermore, regional a

45. Double Patch Antenna Array for Communication and Out-of-band RF Energy Harvesting
Abstract This paper presents a patch antenna array topology for Simultaneous Wireless Information and Power Transfer (SWIPT) applications. The resulting Double Patch Antenna Array (DPA) is composed of two patch antennas operating at different frequencies and fabricated on a unique substrate. One of the patches operates at the 1.8 GHz mobile communication ban

46. ESTRATÉGIAS DE ESCRITA PARA ABORDAGEM DA COMUNICAÇÃO PÚBLICA DA CIÊNCIA NA EDUCAÇÃO EM QUÍMICA
Although the impacts of science discoveries are relevant to society, awareness of this intellectual output is still minimal. Much of this communicative failure between researchers and the general public lies in the disclosure, which contributes to the superficiality and misinterpretations of the content served. Strategies need to be found to improve science

47. Should ethanol be considered a treatment for COVID-19?
Abstract This paper describes the analysis of the effects of a frequency selective surface (FSS) on the characteristics of a microstrip line fed antenna with a bow-tie slot in the ground plane for operation in the frequency range 1 to 10 GHz. The use of the FSS is proposed to miniaturize the antenna structure and increase the number of resonance frequencies
