    Abstract The 2018 LUCAS (Land Use and Coverage Area frame Survey) Soil Pesticides survey provides a European Union (EU)-scale assessment of 118 pesticide residues in more than 3473 soil sites. This study responds to the policy need to develop risk-based indicators for pesticides in the environment. Two mixture risk indicators are presented for soil based, respectively, on the lowest and the median of available No Observed Effect Concentration (NOEC

    Abstract This paper builds a narrative on the early work of Robert E. Lucas Jr., in the late 1960's, which culminated in the modeling and testing of the natural rate of unemployment hypothesis. Lucas's modeling and testing of the natural rate can be found, respectively, in two papers: "Expectations and the Neutrality of Money" (Lucas, 1972a) and "Econometric Testing of the Natural Rate Hypothesis" (Lucas, 1972b). These papers are the synthesis of the two branches of Lucas's research at that time; one on labor market behavior and other on optimal investment by firms. This synthesis changed the way in which the natural rate of unemployment was originally elaborated by Friedman (1968a) and Phelps (1967, 1968), by modeling it in a general equilibrium framework with rational expectations and giving it a proper test. Lucas's research agenda synthesis in the late 1960's was the result of his close interaction with Phelps and Prescott, backed up by his pragmatic equilibrium approach to economics, concerning modeling, econometric estimation and testing. Phelps explicitly suggested a general equilibrium approach to Lucas's labor market modeling, while Prescott helped him in dealing with the rational expectations hypothesis.

    Abstract Estudou-se a Capacidade Predatória de Euborellia annulipes sobre Spodoptera frugiperda em laboratório. O estudo foi conduzido no Laboratório de Entomologia do Setor de Fitossanidade da Universidade Federal da Paraíba (UFPB) à temperatura de 25 ± 1ºC, umidade relativa de 70 + 10% e fotofase de 12h. Notou-se consumo crescente de ovos,podendo ser observado consumo diário médio de 11,06, 49,02, 122,7, 148,09 e 374,9 ovos, do 1° ao 5° instar, respectivamente. A capacidade predatória sobre lagartas de 1° instar de S. frugiperda aumentou de acordo com o seu desenvolvimento, com aumento de,aproximadamente, 14,3 vezes do 1° ao 5° instar, nos dez dias de consumo, sendo que, o 4° e o 5° instares apresentaram consumo diário médio de 25,5 e 26,6, respectivamente, bem superior em comparação aos demais instares; o maior consumo de lagartas de 2º instar pelopredador, ocorreu no 4º e 5º instar, que apresentaram consumo diário médio de 12,8 e 15,1, respectivamente. Verifica-se que E. annulipes demonstra ser predador potencial de ovos e lagartas de S. frugiperda, chegando um adulto a consumir 1.481,2; 89,20 e 48,6 ovos e lagartasde 1º e 2º instares, respectivamente, nos dez dias de consumo. The predatory capacity of Euborellia annulipes on Spodopterafrugiperda was studied in a laboratory setting. The study was conducted in the Laboratory of Entomology of the Division of Plant Protection, Federal University of Paraíba (UFPB) at a temperature of 25 ± 1°C, relative humidity of 70 + 10% and a 12-hour photophase. Thestudy detected growing egg intake, with an average daily consumption of 11.06, 49.02, 122.7, 148.09 and 374.9 eggs, from the first to the fifth instars, respectively. A predatory capacity of fist-instar larvae of S. frugiperda increased in line with its development, with an increase of approximately 14.3 times from the first to the fifth instar, in the 10 days of consumption, whereas the fourth and fifth instars presented an average daily consumption of 25.5 and 26.6, respectively – higher as compared to other instars. The greatestconsumption of second-instar larvae by the predator took place in the fourth and fifth instars, which featured an average daily consumption of 12.8 and 15.1, respectively. It appears that E. annulipes is a potential predator of eggs and larvae of S. frugiperda, with anadult consuming 1,481.2; 89.20 and 48.6 eggs and larvae of first- and second-instars, respectively, during the ten days of monitored consumption.

    Abstract Objetivo: Neste estudo avaliamos o registro de determinados segmentos do exame físico realizado por acadêmicos do 6º ano e médicos residentes em pacientes internados na unidade de Medicina Interna no Hospital São Lucas da PUCRS. Métodos: Seguindo um protocolo previamente estabelecido, foram avaliados retrospectivamente 120 prontuários escolhidos de forma aleatória, entre o período de janeiro de 2000 a março de 2002. Resultados: Embora alguns segmentos do exame são registrados em mais de 90% dos casos (exame cardiovascular, pulmonar e abdominal), o exame é incompleto em todos os prontuários. O exame neurológico exemplifica um problema particularmente sé- rio que identificamos nesta avaliação. Mesmo em pacientes que apresentam sintomas ou queixas neuroló- gicas o exame não é realizado ou registrado adequadamente. Alguns segmentos específicos como exame de linfonodos, tireóide, fundoscopia, otoscopia, toque retal, testículos ou mamas são registrados somente numa minoria absoluta dos casos. Conclusão: Entendemos que a falta de modelo e orientação por parte do corpo de professores é o principal motivo que explica esta situação. A necessidade de reverter esta realidade, desenvolvendo estratégias eficazes é imperativa

    Abstract Microbes are traditionally regarded as planktonic organisms, individual cells that live independently from each other. Although this is true, microbes in nature mostly live within large multi-species communities forming complex ecosystems. In these communities, microbial cells are held together and organised spatially by an extracellular matrix (ECM). Unlike the ECM from the tissues of higher eukaryotes, microbial ECM, mostly that of yeasts, is still poorly studied. However, microbial biofilms are a serious cause for concern, for being responsible for the development of nosocomial infections by pharmacological drugs-resistant strains of pathogens, or for critically threatening plant health and food security under climate change. Understanding the organization and behaviour of cells in biofilms or other communities is therefore of extreme importance. Within colonies or biofilms, extremely large numbers of individual microbial cells adhere to inert surfaces or living tissues, differentiate, die or multiply and invade adjacent space, often following a 3D architectural programme genetically determined. For all this, cells depend on the production and secretion of ECM, which might, as in higher eukaryotes, actively participate in the regulation of the group behaviour. This work presents an overview of the state-of-the-art on the composition and structure of the ECM produced by yeasts, and the inherent physicochemical properties so often undermined, as well as the available information on its production and delivery pathways.

    Abstract Layered Double Hydroxides (LDH) are synthetic materials nanostructured in two dimensions that present positively charged layers with interspersed anions for charge and structure balancing. Being recognized as a promising material for various applications, a complete exploration of its possible attractive properties and its synthesis process is essential. However, drying, a necessary step in the process, is still little studied. This work aimed to produce MgAl-CO
