13. THE DEVELOPMENT OF LANGUAGE AND ITS INTERACTION WITH OTHER ASPECTS OF COGNITION: THE CASE OF MEDIAL WH-QUESTIONS IN ENGLISH AND IN BRAZILIAN PORTUGUESE
Abstract Preschool children acquiring English and Brazilian Portuguese display a peculiar behavior when prompted to produce multi-clause wh-questions. In elicited production tasks, structures with an extra wh-element in medial position are sometimes produced. Such medial questions are impossible in the adult languages being acquired. Following a hypothesis p

14. O Que Faz um Artigo ser Mais Citado?
Abstract The Guacuí and Batatal lineaments in the southern region of the state of Espírito Santo (southeastern Brazil) can be traced from satellite images for tens of kilometers. They are considered shear zones associated to the final tectonic stages of the Araçuaí-West Congo (A-WC) Orogen during the Ediacaran-Cambrian period. In order to understand thei

16. Evaluation of autolysis induced histologic alterations in skeletal muscle tissue of non-traditional meat animals
Abstract Raw meat is characterized by various natural cellular processes that lead to its chemical content alteration. The purpose of the present study is to evaluate autolysis induced histologic alterations in skeletal muscle tissue of cow elk. In this study the authors used skeletal muscle tissue of 2-year-old cow elk. The tissue was sampled from m. quadri

17. ALTERNATIVES TO ESTIMATE THE VOLUME OF INDIVIDUAL TREES IN FOREST FORMATIONS IN THE STATE OF MINAS GERAIS, BRAZIL
ABSTRACT The objective of this study was to compare different alternatives to estimate the stem volume of individual trees in four different forest formations in the Minas Gerais state, Brazil. The data were obtained in a forest inventory procedure performed by the Minas Gerais Technological Center Foundation. The stem volumes were computed by the Smalian ex

18. Crystallographic Changes Accompanying the Verwey Transition in a Magnetite from Steatite
The crystallographic structural analysis of the magnetite of a steatite rock at 298 K, (saturation magnetization, σ = 95.0 J T-1 kg-1) showed two cubic networks and, below Verwey temperature (TV ca.120 K) a monoclinic structure, basing on their cell dimensions and different transitional behaviors when reducing the temperature. A monoclinic structure was ide

19. Pesquisa em doenças inflamatórias intestinais no Brasil: um passo à frente rumo ao cuidado dos pacientes
Maytenus distichophylla is a medicinal species used in Northeast of Brazil. The hexane (HE), chloroform (CE), ethyl acetate (EAE) and methanol (ME) extracts and compounds from its roots were evaluated for their protective activity against Staphylococcus aureus and Candida albicans. The cytotoxicity for chronic myeloid leukemia (K562), acute monocytic leukemi

22. DOIS NOVOS ALCALOIDES AZAFENANTRENO DE Anaxagorea dolichocarpa Sprague & Sandwith
A chemical investigation of Anaxagorea dolichocarpa Sprague & Sandwith, a member of Annonaceae family, was carried out. The ethanolic extract from the roots of this plant led, by chromatography tecniches, to isolation of the new azaphenanthrene alkaloids dolichocarpine (1) and 9-methoxyeupolauramine (2), besides the known alkaloids eupolauramine (3), 3-metho

23. Crystal Structure and 1H NMR Experimental and Theoretical Study of Conformers of 5-Methyl-1-(4’-methylphenylsulfonylamino)-1H-[1,2,3]-triazole-4-carboxylic Acid Ethyl Ester and 5-Methyl-1-(phenylsulfonylamino)-1H-[1,2,3]-triazole-4-carboxylic Acid Ethyl Ester
We reported experimental and theoretical investigation of conformers of 1,2,3-triazole derivatives, substances of exclusively synthetic origin, subject of extensive studies, because of several biological properties, such as antiviral, antimicrobial and antileishmaniasis. We reported molecular/supramolecular X-ray structures of antiophidian compounds I and II

24. 3-Aminofurostane Alkaloids from Solanum paniculatum (“Jurubeba Verdadeira”) Roots
The roots of Solanum paniculatum (Solanaceae) have extensively been used in folk medicine to treat liver infections and as a diuretic. Ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS/MS) were used for the profiling and structural characterization of alkaloids from the roots of S. paniculatum.
