ABSTRACT
ABSTRACT Some psyllids transmit 'Candidatus Liberibacter solanacearum' (Lso), the causal agent of devastating plant diseases of cultivated Solanaceae and Apiaceae. The recent detection of Bactericera cockerelli and Lso in Ecuador seriously threatens these crops in South America. There, neither the role of native psyllids in the Lso epidemiology nor the psyllid fauna of vegetables are known. With the aim to identify potential vectors and risk scenarios for the spread of Lso in South America, a survey of the psyllid fauna of Solanaceae and Apiaceae crops and associated weeds was conducted in Brazil. Samples were taken at 29 localities in four states. A total of 2857 specimens were sampled, representing at least 37 species of 23 genera and seven families. The most frequent species on carrot, chilli pepper and potato were Russelliana solanicola, R. capsici and Isogonoceraia divergipennis, respectively. Immatures of R. capsici were found on chilli pepper and of R. solanicola on carrot and potato, confirming these plants as hosts. The two psyllid species have been suspected previously to transmit plant pathogens of unknown identity. Russelliana solanicola is one of the few polyphagous species. Here the species is reported for the first time from carrot. Recent collections in Rio Grande do Sul suggest that Solanum laxum represents the original host of R. capsici, which subsequently shifted to chilli pepper. Both, adaptation to agricultural crops and the possibility of ability to transmit pathogens, make the two Russelliana species dangerous potential vectors of Lso and other plant pathogens in South America.
ABSTRACT
A fundamentally new direction in the theory and practice of quantum nonlinear phenomena in non-ideal and very close to non-degenerate plasma has been developed, for the first time the existence of a new state of matter-imperfect plasma-quantum plasma condensate, combining the properties of ordinary liquid and ionized plasma, has been theoretically predicted and confirmed. The quantum non-ideality of non-degenerate plasma and the exchange interaction of electrons in it, leading to effective energy release in the plasma process under study, were investigated. The directions of use of this energy have been determined: for heating, lighting, conversion by means of photocells or MHD-movements into electrical, for obtaining energy in the ultraviolet range. Particular attention in the work is paid to one of the most popular applications of quantum non-ideal plasma - for heating, at which its plasma combustion occurs, and the generation of electrical energy based on the use of a quantum plasma-MHD generator with plasma delamination. Detection of this kind of phase state of non-ideal non-degenerate plasma and its use in engineering and technology will create a fundamentally new effective energy system corresponding to the Sixth Technological Order on a global scale. This source of energy is the only environmentally friendly, not destroying or polluting our planet, and its use cleanses our ecosphere. The paper shows that the use of existing energy undermines people's health, reduces their immunity and resistance to coronaviruses. Measures have been proposed to end coronavirus pandemics on Earth. Information is provided on the technical capabilities of the proposed fundamentally new structures - Universal Modules of Industrial Disintegrators / Activators, which allow to implement grandiose, payback state projects on the basis of the developed nanotechnologies, representing the work of tens of millions of people
ABSTRACT
O presente artigo aborda os propósitos de regionalização da rede hospitalar portuguesa durante o regime ditatorial do Estado Novo (1933-1974), lançados no após Segunda Guerra Mundial. Almejando um sistema hospitalar coordenado com base regional, o governo português limitou-se a comparticipar a construção e a remodelação de edifícios, relegando as múltiplas tarefas envolvidas no funcionamento hospitalar para instituições particulares, o que dificultou o desenvolvimento e o acesso a cuidados de saúde a uma parte significativa da população. Com base na análise de viagens de estudo realizadas por administradores hospitalares e engenheiros sanitários nas décadas de 1940 e 1950, sobretudo a países europeus como Itália, França e Inglaterra, pondera-se acerca da importância dos contatos com redes internacionais de especialistas e da influência exercida pelos exemplos estrangeiros sobre as medidas de organização da assistência hospitalar em Portugal estabelecidas nos anos seguintes.

This article analyzes the regionalization of Portugal's hospital network during the "New State" dictatorial regime (1933-1974), launched after the second world war. In an attempt to create a regionally-based hospital system, the Portuguese government limited itself to subsidizing the construction and refurbishment of buildings, relegating the multiple tasks involved in hospital management to private organizations, hampering access to health care for a significant part of the population. Through the analysis of study trips made by hospital administrators and sanitary engineers in the 1940s and 1950s, mainly to European countries such as Italy, France and England, this article reflects on the importance of contacts with international networks of experts and influence of foreign experiences on the approach to the organization of hospital care in Portugal adopted in subsequent years.

A list of aquatic and semiaquatic Heteroptera from a collecting trip to Pitinga, a village in a mining area in the County of Presidente Figueiredo in the Central Amazon is presented. Identified were fifty five species of Heteroptera, distributed in 13 families. Among the insects collected, some are new records for this Amazonian region and in addition 3 apparently undescribed species of Microvelia and one of Paravelia remain for further study.
Uma lista de heterópteros aquáticos e semi-aquáticos coletados durante uma viagem a Pitinga, uma área de mineração no município de Presidente Figueiredo, na Amazônia Central, é apresentada. Foram coletadas 55 espécies de Heteroptera, distribuídas em 13 famílias. Entre os insetos coletados, alguns são registros novos para essa região amazônica.
