13. Sensitivity of caloric test and video head impulse as screening test for chronic vestibular complaints
OBJECTIVE: This study compared the results of the caloric test with those of the video head impulse test obtained during the same session and evaluated whether the former can be used to screen for non-acute vestibular dysfunction. METHODS: A total of 157 participants complaining of dizziness with vestibular characteristics of varying durations and clinical

14. Breeze Potential Along the Brazilian Northern and Northeastern Coast
ABSTRACT The breeze potential along the Brazilian northern and northeastern coast was studied using wind data from the Climate Forecast System Reanalysis for the period between 1980 and 2010. March and September were considered, which are representative of the rainy and dry (or less rainy) periods, respectively. The Brazilian northern and northeastern coast

15. Biological characterization of compounds from Rhinella schneideri poison that act on the complement system
Background The skin secretions of toads of the family Bufonidae contain biogenic amines, alkaloids, steroids (bufotoxins), bufodienolides (bufogenin), peptides and proteins. The poison of Rhinella schneideri, formerly classified as Bufo paracnemis, presents components that act on different biological systems, including the complement system. The aim of this

16. Bothrops snake venoms and their isolated toxins, an L-amino acid oxidase and a serine protease, modulate human complement system pathways
Background Activation of the complement system plays an important role in the regulation of immune and inflammatory reactions, and contributes to inflammatory responses triggered by envenomation provoked byBothrops snakes. The present study aimed to assess whether Bothrops jararacussuand Bothrops pirajai crude venoms and their isolated toxins, namely serine

17. Purification procedure for the isolation of a P-I metalloprotease and an acidic phospholipase A 2 fromBothrops atrox snake venom
Background Snake venoms are complex mixtures of inorganic and organic components, mainly proteins and peptides. Standardization of methods for isolating bioactive molecules from snake venoms is extremely difficult due to the complex and highly variable composition of venoms, which can be influenced by factors such as age and geographic location of the specim

18. Less or More Intensive Crop Arable Systems of Alentejo Region of Portugal: what is the sustainable option?
Competitiveness of traditional arable crop system of Alentejo region of Portugal has been questioned for long. Discussion and research on the sustainability of the system has evolved on two contrasted alternative options for production technologies to traditional system. On the one hand reduced and no tillage systems aim to more extensive technical operation

19. La comunicación científica en Uruguay: estudio de las publicaciones de los investigadores activos del Sistema Nacional de Investigadores (2009-2010)
Scholarly communication in Uruguay was studied considering the publications reported in the researchers' curricula vitae from the National System of Researchers of the National Agency for Research and Innovation of Uruguay. An ad-hoc database was developed, where data relative to variables such as field of knowledge, kind of publication, type of responsibili

20. Genetic diversity and antimicrobial resistance in Streptococcus agalactiae strains recovered from female carriers in the Bucharest area
For the first time, we used multilocus sequence typing (MLST) to understand how Romanian group B streptococcus (GBS) strains fit into the global GBS population structure. Colonising isolates recovered from adult human females were tested for antibiotic resistance, were molecularly serotyped based on the capsular polysaccharide synthesis (cps) gene cluster an

21. Automatic evaluation and data generation for analytical chemistry instrumental analysis exercises
In general, laboratory activities are costly in terms of time, space, and money. As such, the ability to provide realistically simulated laboratory data that enables students to practice data analysis techniques as a complementary activity would be expected to reduce these costs while opening up very interesting possibilities. In the present work, a novel me

22. Using value-focused thinking in Brazil
Value-Focused Thinking (VFT) provides a systematic approach to structure complex decisions for subsequent analysis. It is a powerful complement to decision analysis and its application has been growing in recent years. This paper discusses the application of VFT in Brazil to three problems in different contexts: water management, information system/informati

23. Técnica de realidade virtual para manipulação e deformação de superfícies NURBS
The Virtual Reality (VR) mainly deals with the creation of three-dimensional environments generated in real time and made available for multisensory interaction with different devices. A high processing capacity and modeling environments is required for applications of this nature. These applications currently extend to various productive sectors such as ind

24. Integração entre redes heterogêneas de ativos digitais: modelo híbrido de metadados baseado em meta-modelos dinâmicos
The increased production of digital assets in enterprise environments makes digital asset management an increasingly complex task, since we must make use of well-defined metadata, so that you can easily find and use assets from different repositories. However, obtaining a standardized model that cover the peculiarities of all involved, is usually a highly co
