The genus Atriplex Linnaeus (1753: 1052) (Chenopodiaceae Vent.; placed in Amaranthaceae Juss. s. l. in APG IV 2016) comprises about 300 species distributed mainly in subtropical, temperate, and subarctic regions of the world and is mostly adapted to dry conditions on often saline soils (Sukhorukov & Danin 2009, Kadereit et al. 2010, Iamonico 2013, APG IV 2016). The genus is highly diverse in Eurasia, Australia and North America. South America is another centre of diversity with ca. 55 species, 45 of which are considered as native (Brignone et al. 2016). A recent and exhaustive taxonomical synopsis of Atriplex for South America was published by Brignone et al. (2016), but there are also regional taxonomic revisions, e.g., for Chile by Rosas (1989), or Argentina by Múlgura de Romero (1981, 1982 & 1984).

This paper considers the characteristics of satellite television transmission in the world. An overview of the development of satellite television is given through the following characteristics: broadcasting systems - analog and digital (SDTV, HDTV, UHDTV), frequency band (C, Ku, Ka), broadcasting standards (DVB-S, DVB-S2, DigiCipher, DSS), as well as the availability of TV services Free-To-Air TV (FTA) and PAY TV. All of these characteristics were considered both at the global and at the regional level: North America, South America, Europe, Africa, Russia, Asia, and Australia. The gathered data are presented in tabular form and presented graphically for the period from 1996 to 2018. Based on the presented results, an analysis of the development of satellite television transmission was carried out in accordance with the characteristics of the broadcast.

A novel coronavirus first reported from China has resulted in a formidable outbreak globally threatening millions of human lives with unprecedented challenges. Society needs effective information source to combat this pandemic. Academic institutions would play an important role in disseminating science-based information and planning pandemic crisis. This study aims to examine how academic institutions around the world have been working in combating COVID-19 pandemic. Two hundred and thirty three high ranking universities representing 44 countries from six continents, viz. Africa, Asia, Europe, North America, South America, and Oceania were selected and their websites visited. Any information on COVID-19 updated in the websites were noted and classified. Universities from developed world (North America, Europe) and Oceania were found to be actively disseminating up-to-date information on COVID-19 with compared to those from developing world. All universities in Oceania, 96.66% universities in North America, 96.55% in Europe, 83% in South America, 61.25% in Asia, and 56% in Africa had information regarding COVID-19 in their websites. The high income coutries were facing high casulaties of the disease, and majority of their universities (85.71%) were disseminating up-to-date information through their websites. There exists a gap between the universities of developed and developing world in disseminating COVID-19 pandemic information.
