Opis:
The extreme right hate speech propagated currently in Brazil addresses a broad social spectrum, from feminist movements to traditional communities. The academic community and higher education institutions are also targets, as they are identified as poles of democratic resistance. Specific hate speech towards academy in Brazil is the subject of this paper. The persecution of academic community and knowledge itself occurs through the discursive dispute especially on social networks, and thus in this analytical exercise, we looked up at Facebook’s largest bolsonarista’s group – the “Jair Bolsonaro Presidency Support Group”, which brings together 317,000 members. We analyzed the memetic discourse on the page, focusing memes that were published between April and June 2019, thematizing higher public education, and presenting a bimodal verb-visual composition. These criteria led to the collection of 115 memes analyzed with the support of a QDA package. Analysis reveals the disqualification of university institutions and their actors through ironies, negative associations including stereotypes, simplification of debate to the shallower. Students are often associated with nudity as immorality, professors of indoctrination and ridicule, protesters of ignorance, or bad character. Political debate is reduced to extreme left-right polarization, with the criminalization of the left.

Opis:
In this article, a novel ultra wideband (UWB) small antennas based on the composite right/left-handed transmission lines structures are proposed. The antennas are pre- sented with best in size, bandwidth and radiation patterns. Their physical size and the operational frequency depend on the unit cell size and the equivalent transmission line model parameters of the CRLH-TL. To realize characteristics of frst proposed model, Q-shaped gaps printed into rectangular radiation patches are used. The antenna based on composite right/left-handed transmission lines is composed of two unit cells, each of which occupies only 10.8 x 8.6 mm and covers the 2.7{9.3 GHz bandwidth for VSWR < 2. The peak gain and radiation effciency, are 5.78 dBi and 42.1% 9.3 GHz, respectively. Moreover, the second designed antenna has the same size and enhancement bandwidth, gain and radiation effciency than the rst proposed antenna with similar design procedure. It is constructed of the printed Q-shaped four unit cells. The length, width and height are 21.6, 8.6 and 1.6 mm, respectively, and it covers 4.1{11.7 GHz bandwidth for VSWR < 2 having highest gain (7.18 dBi) and radiation effciency (92.69%) at 4.1 GHz.
