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.

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).

Abstract Novel Coronavirus (2019-nCoV [SARS-COV-2]) was detected in humans during the last week of December 2019 at Wuhan city in China, and caused 24 554 cases in 27 countries and territories as of 5 February 2020. The objective of this study was to estimate the risk of transmission of 2019-nCoV through human passenger air flight from four major cities of China (Wuhan, Beijing, Shanghai and Guangzhou) to the passengers' destination countries. We extracted the weekly simulated passengers' end destination data for the period of 1–31 January 2020 from FLIRT, an online air travel dataset that uses information from 800 airlines to show the direct flight and passengers' end destination. We estimated a risk index of 2019-nCoV transmission based on the number of travellers to destination countries, weighted by the number of confirmed cases of the departed city reported by the World Health Organization (WHO). We ranked each country based on the risk index in four quantiles (4th quantile being the highest risk and 1st quantile being the lowest risk). During the period, 388 287 passengers were destined for 1297 airports in 168 countries or territories across the world. The risk index of 2019-nCoV among the countries had a very high correlation with the WHO-reported confirmed cases (0.97). According to our risk score classification, of the countries that reported at least one Coronavirus-infected pneumonia (COVID-19) case as of 5 February 2020, 24 countries were in the 4th quantile of the risk index, two in the 3rd quantile, one in the 2nd quantile and none in the 1st quantile. Outside China, countries with a higher risk of 2019-nCoV transmission are Thailand, Cambodia, Malaysia, Canada and the USA, all of which reported at least one case. In pan-Europe, UK, France, Russia, Germany and Italy; in North America, USA and Canada; in Oceania, Australia had high risk, all of them reported at least one case. In Africa and South America, the risk of transmission is very low with Ethiopia, South Africa, Egypt, Mauritius and Brazil showing a similar risk of transmission compared to the risk of any of the countries where at least one case is detected. The risk of transmission on 31 January 2020 was very high in neighbouring Asian countries, followed by Europe (UK, France, Russia and Germany), Oceania (Australia) and North America (USA and Canada). Increased public health response including early case recognition, isolation of identified case, contract tracing and targeted airport screening, public awareness and vigilance of health workers will help mitigate the force of further spread to naïve countries.

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.

Insight Into

AbstractTo gain more insight into evidentiality, the grammatical marking of information source, it is worth studying the category in its relation to other grammatical categories. This study explores tensed evidentials, morphemes in which tense and evidentiality are fused, in 36 languages from four macro-areas (North America, South America, Eurasia, and Papunesia). The study reveals several interactions between tense values and evidential values. As opposed to what has been claimed, firsthand future evidentials seem to exist. Visual and non-visual evidentials occur equally with present and past, whereas mental activity evidentials and reportative evidentials are much more limited to the past. These findings conform to the logic of tense: every type of evidentiality can be gathered in the past, whereas some are less suited for present or future. As a result, we find exceptionless implicational hierarchies of the form

On December 31, 2019, WHO was informed of cases of pneumonia of unknown cause in Wuhan City, China. A novel coronavirus was identified as the cause by Chinese authorities on January 7, 2020 and was provisionally named "2019-nCoV". This new Coronavirus causes a clinical picture which has received now the name COVID-19. The virus has spread subsequently worldwide and was explained on the 11th of March, 2020 by the World Health Organization to the pandemic.

Podosphaera Leucotricha

Abstract A description is provided for Podosphaera leucotricha. Information is included on the disease caused by the organism, its transmission, geographical distribution, and hosts. HOSTS: On Malus spp., chiefly on M. pumila (apple), peach (Prunus persica), quince (Cydonia ualgaris) and Photinia spp. also attacked (Hirata, 1966). Also reported on almond fruit (43, 2544). DISEASE: Powdery mildew of apple. GEOGRAPHICAL DISTRIBUTION: Africa (? Kenya, Rhodaia, South Africa, Tanzania); Asia (China, India, Israel, Japan, U.S.S.R.); Australia and New Zealand, Europe (widely distributed) North America (Canada and U.S.A.); South America (Argentina, Brazil, Chile, Colombia, Peru). (CMI map 118). TRANSMISSION: Overwinters on host as dormant mycdium in blossom buds. The role of deistothecia in overwintering is doubtful. Spread by wind-borne conidia (Anderson, 1956).
