On the Impossibility of an Exact Imperfect Monitoring Folk Theorem

It is shown that, for almost every two-player game with imperfect monitoring, the conclusions of the classical folk theorem are false. So, even though these games admit a well-known approximate folk theorem, an exact folk theorem may only be obtained for a measure zero set of games. A complete characterization of the efficient equilibria of almost every such game is also given, along with an inefficiency result on the imperfect monitoring prisoner s dilemma.

Studies on the constituents of a Brazilian folk infusion. Isolation and structure elucidation of new triterpene saponins from Ilex amara leaves

The isolation of three new triterpene saponins 3beta-O-beta-D-glucopyranosyl-(1-->3)-alpha-L-2-O-acetylara-binopyranosylolean-12-en-28-oic acid 28-O-beta-D-glucopyranosyl ester (2), 3beta-O-beta-D-glucopyranosyl-(1-->2)-alpha-L-O-arabinopyranosylurs-12-en-28-oic acid (3), and 3beta-O-beta-D-glucopyranosyl-(1-->2)-beta-D-O-galactopyranosylurs-12-en-28-oic acid (4) together with five known saponins and one flavonoid glycoside from the aqueous infusion of flex amara (Vellozo) Loes. leaves is reported. All structures were elucidated by spectroscopic methods, including the concerted application of one-dimensional (H-1, TOCSY, C-13, and C-13 DEPT NMR) and two-dimensional NMR techniques (DQF-COSY, HSQC, and HMBC).

Espécies de uso medicinal popular nativas e introduzidas cultivadas em cinco municípios do estado do amazonas

The objective if this work was a survey of medicinal plants plus commonly cultivated in quintais in Amazon State, Brazil. The work was carried out in five counties at the Solimões/Amazonas and Negro Rivers, by questionnaires, interviews and collections of botanical materials, using the literature to define the geographic origins. It was showed 105 species of medicinal plants, with average of 13 per house. The Amazonian plants, in general wood plants, meaning 10,9 percent of the total of species that was survey, with predominance of the American continent plants out of Amazonian (38,2 per cent). The major group was herbaceous or shrubs exotic plants, aromatics. In general, the peoples unknown the origin of the species of medicinal plants that use day after day.

Biomass production and chemical composition of essential oil of Piper callosum as affected by spacing in Manaus, Amazonas State, Brazil

The family Piperaceae contains nearly 2000 species, most of them distributed in two genera, Piper and Peperomia. In Brazil circa 170 Piper species are found, mainly in tropical areas Their use ranges from flavoring and culinary to raw material for pharmaceutical and cosmetic industry. One of these species, Piper callosum, is used in folk medicine in the Amazon area. The objective of this study was to evaluate the production of biomass (aerial parts) as well as yield and composition of the essential oil from the leaves, according to different spacing between cultivated plants at Embrapa Western Amazon, in Manaus, State of Amazonas, Brazil. The experimental design was randomized blocks, with four treatments and seven replicates with six plants. Biomass production was inversely proportional to the spatial arrangements, with the greatest biomass production (1034.93 kg/ha) in the shortest spacing (E1), although no statistical difference was verified between E3 and E4. The same response was observed for the production of essential oil. The chemical composition of the oil was not affected by spacing, and major compounds found were safrole (59.1%), beta-pinene (8.3%), alpha-pinene (6.5%), methyl eugenol (6.3%) and 1,8-cineole (4.1).

Por uma história do livro e da leitura no Pará: o caso da Guajarina, editora de folhetos de cordel (1922-1949)

A presente dissertação analisa a atuação da editora Guajarina na divulgação da literatura de cordel no Pará a partir de uma história do livro e da leitura, tendo como recorte o período de 1922 a 1949. Nesse sentido, procuramos explorar algumas questões relacionadas ao cordel que não se reduzem aos textos, tais como: a problematização da associação entre cordel, cultura popular e folclore; a produção e circulação dos folhetos; e as representações e estratégias dos poetas nas histórias de crimes. Desse modo, a análise da Guajarina e de seus folhetos nos permite entender alguns significados das múltiplas práticas de leitura da sociedade no contexto da primeira metade do século XX. Além dos folhetos, também são utilizadas fontes como jornais, revistas e coleções encadernadas de modinhas.

Milton a poem in 2 books: influência e afluência na linguagem poético-visual de William Blake

Sob a influência de seu predecessor mais forte, John Milton, o poeta, pintor e gravurista William Blake reage a essa influência incorporando-a dinamicamente à sua poesia. Porém, a reação à influência poética é mais abrangente que a incorporação do Paradise Lost, de John Milton, ao seu poema Milton: a Poem in Two Books e conduz o autor a criar uma linguagem poética na qual as referências extratextuais verbais e visuais são transferidas, por meio de metalinguagem, para o interior do próprio poema. Sem referências claras para ajudá-lo, o leitor é induzido a criar suas referências subjetivas e dar sentido ao texto, transformando-se, assim, de leitor passivo, em leitor/criador ativo. Palavras-chave: William Blake; iluminuras; John Milton; influência; reação; sistema verbal/visual.

Reproductive toxicology and clastogenic evaluation in mice of a phytotherapeutic formulation obtained from Cinchona calisaya Weddel (Rubiaceae) used in Brazilian folk medicine as female fertility stimulant

Ethnopharmacological relevance: In Brazil, a phytotherapeutic preparation produced from a standardized tincture of Cinchona calisaya Weddel such that each mL of product contains 400 mu g of quinine, known in Portuguese as Agua Inglesa (R) (English water), is indicated by the manufacturer as a tonic, appetite stimulant, and digestive. However, this preparation has long been used in folk medicine as a female fertility stimulant. Despite its widespread use in folk medicine to stimulate female fertility, no study has been undertaken to assess the potential teratogenic and genotoxic effects of this phytotherapeutic preparation. The aim of the present study was to investigate possible toxic reproductive effects in mice caused by exposure to Agua Inglesa (R), either before mating or during the pre- and post-embryo implantation periods. The genotoxic potential was evaluated using the micronucleus assay.Material, Methods, and Results: Virgin female mice, with at least one estrous cycle evidenced by vaginal cytology, were divided into five groups of 15 individuals each (Group I - control, Group II - treated with ethanol solution at 16%, Groups III, IV and V treated with phytotherapeutic preparation at 1.5 mL/kg/day, 3.0 mL/kg/day and 4.5 mL/kg/day, respectively). After the first 28 days of treatment, females were caged individually with adult fertile males. Pregnant females continued to receive treatment for seven days (preimplantation period). Body weight was recorded weekly during treatment. Signs of toxicity (weight loss, food intake, piloerection, apathy, prostration, diarrhea, seizures, behavioral changes, and locomotion) were also observed. The females were sacrificed on the 15th day of pregnancy, uterine horns were evaluated for implantation, and the placental index was recorded. In the micronucleus test, 2000 polychromatic erythrocytes (PCE) per animal, obtained from bone marrow, were scored. Results The results showed that exposure of the females during the pre- and post-implantation periods did not significantly alter the reproductive capacity (p < 0.05); however, in higher dose (three times human dose)reduction of fetal weight was observed. There was no difference between the control and phytotherapeutic preparation (p > 0.05) in terms of the average number of micronucleated polychromatic erythrocytes.Conclusions: Although folk medicine suggests that the Agua Inglesa (R) preparation is useful as a female fertility stimulant, no such effect was confirmed in mice.
