14. Draft genome sequence of Bradyrhizobium manausense strain BR 3351T, an effective symbiont isolated from Amazon rainforest
ABSTRACT The strain BR 3351T (Bradyrhizobium manausense) was obtained from nodules of cowpea (Vigna unguiculata L. Walp) growing in soil collected from Amazon rainforest. Furthermore, it was observed that the strain has high capacity to fix nitrogen symbiotically in symbioses with cowpea. We report here the draft genome sequence of strain BR 3351T. The infor

16. DEVELOPMENT OF A SECOND TYPE ELECTRODE BASED ON THE SILVER/SILVER IBUPROFENATE PAIR FOR IBUPROFEN QUANTIFICATION IN PHARMACEUTICAL SAMPLES
Ibuprofen is a widely used pharmaceutical because of its therapeutic properties; it is considered a safe medicament, thus it does not require medical prescription to be sold. However, in order to ensure consumer's health it is indispensable that the pharmaceutical industry relies on analytic methods for its quantification. Potentiometry has proven to be a su

18. Adsorption of remazol brilliant blue on an orange peel adsorbent
A novel orange peel adsorbent developed from an agricultural waste material was characterised and utilised for the removal of Remazol Brilliant Blue from an artificial textile-dye effluent. The adsorption thermodynamics of this dye-adsorbent pair was studied in a series of equilibrium experiments. The time to reach equilibrium was 15 h for the concentration

19. Human rhinovirus infections in symptomatic and asymptomatic subjects
The role of rhinovirus asymptomatic infections in the transmission among close contacts subjects is unknown. We tested health care workers, a pair of one child and a family member and immunocompromised patients (n =191). HRV were detected on 22.9% symptomatic and 3.6% asymptomatic cases suggesting lower transmission among contacts.

20. Assessment of inter- and intra-cultivar variations in olive using SSR markers
Olive (Olea europaea L.) production in the world has been made by using many cultivars, and the genetic uniformity of commercial cultivars is important for standard olive oil and table olive production. The genetic variation among and within commonly cultivated olive cultivars in Turkey was analyzed using SSR markers. A total of 135 leaf samples were collect

21. Studies on the development of spectrophotometric method for the determination of haloperidol in pharmaceutical preparations
A spectrophotometric method based on the formation of ion-pair complex between haloperidol and eriochrome black T (EBT) at pH 1.85 has been described. The formed complex was extracted quantitatively into chloroform and measured at 510 nm. Infra red (IR) studies were performed to confirm the formation of ion-pair complex. Beer's law was obeyed in the concentr

22. Integrated experimental biophysics and molecular dynamics simulations of biomolecules in solution - the interaction of nuclear receptors with DNA response elements and the inter-domain dynamics of Cellobiohydrolase I / Estudos por modelagem e dinâmica molecular integradas a técnicas físicas para biomoléculas em solução - interação de receptores nucleares a elementos responsivos no DNA e dinâmica inter-domínios da celobiohidrolase I
Collective motions play a fundamental role in solution biomolecule dynamics and energetics. These movements can couple very distant regions in the protein structures affection, for instance, allosteric mechanisms, the establishment of macromolecular complexes, and on the integrated function of multidomain proteins as molecullar machines. In this thesis, we p

23. Desenvolvimento de procedimentos eletroanalíticos para a determinação de antioxidantes e corantes em produtos alimentícios empregando um eletrodo de diamante dopado com boro / Development of electroanalytical procedures for the determination of antioxidants and colorants in food samples using a boron-doped diamond electrode
The following topics were investigated in this thesis: a) the electrochemical response of a boron-doped diamond electrode, after different electrochemical pretreatments, for two antioxidants (butylated hydroxyanisole BHA and butylated hydroxytoluene BHT) and three food colorants (tartrazine TT, sunset yellow SY, and brilliant blue BB); b) the development of

24. Avaliação das guias condilar e incisal em função da curva de compensação e da altura das cúspides - Releitura das Leis de Articulação de Hanau / Evaluation of condylar guidance and incisal guidance according to the compensating curve and cusp heights. A review of Hanaus laws of articulation
The objective of this in vitro study was to evaluate the variation of the saggital guidances (condylar guidance and incisal guidance) according to plane of orientation (prominence and inclination) and cusp heights during mandibular protrusive movements. The relationship between afore mentioned factors were assessed through both analogical and digital methods
