Dois novos metabólitos, 2,4-diidroxi-5,6-dimetil benzoato de etila (1) e phomopsilactona (2) foram isolados de Phomopsis cassiae, um fungo endofítico de Cassia spectabilis. As estruturas destes compostos foram elucidadas por dados espectrométricos de 1D e 2D RMN, EM e IV. As substâncias 1 e 2 exibiram forte atividade antifúngica contra os fungos fitopatogênicos Cladosporium cladosporioides e C....

Abstract We generalize the greedy and lazy $\beta $ -transformations for a real base to setting of alternate bases ${\boldsymbol {\beta }}=(\beta _0,\ldots ,\beta _{p-1})$ , which were recently introduced by first second authors as particular case Cantor bases. As in case, these new transformations, denoted $T_{{\boldsymbol }}}$ $L_{{\boldsymbol respectively, can be iterated order generate digi...

To investigate neural coding characteristics in the human primary somatosensory cortices, the cortical representation of two fingers with different levels of functional skill has been focused (the thumb –high dexterous– and the little finger –low dexterous–). The finger dexterity was scored by the Fingertip writing test. In the two hemispheres, dynamic neural synchronization was analysed in the...

We find radial and nonradial solutions to the following nonlocal problem $$-\Delta u +\omega u= \big(I_\alpha\ast F(u)\big)f(u)-\big(I_\beta\ast G(u)\big)g(u) \text{ in } \mathbb{R}^N$$ under general assumptions, spirit of Berestycki Lions, imposed on $f$ $g$, where $N\geq 3$, $0\leq \beta \leq \alpha<N$, $\omega\geq 0$, $f,g:\mathbb{R}\to \mathbb{R}$ are continuous functions with corresponding...

Using a mobile-phone-based experience-sampling technology in a sample of 378 individuals ranging from 14 to 86 years of age, we investigated age differences in how people want to influence their feelings in their daily lives. Contra-hedonic motivations of wanting either to maintain or enhance negative affect or to dampen positive affect were most prevalent in adolescence, whereas prohedonic mot...

Use of the Web brought 32% (8/25) increase in performance Experiments Coping with five kinds of anaphoric expressions (see paper) Invoking PALAVRAS, a broad-coverage parser for Portuguese [Bick 2000] Dealing with sentence arguments (object, subject, etc.) as candidates Shallow reference resolution algorithm: 71% accuracy in general (over 122 questions) Producing several questions from the origi...

Introduction: Breast cancer is one of the most common known cancers in women all around the world. It is the most common cause of death in women after lung cancer. Radiotherapy is a method for therapy of cancer in which certain dose of high energy radiations is used to destruct cancer cells. Radiotherapy is designed so that radiation of eartain does to the target area in body i...
