2. A comparative study between two different conventional working electrodes for detection of Δ9-tetrahydrocannabinol using square-wave voltammetry: a new sensitive method for forensic analysis
A maconha é uma das drogas ilícitas mais consumidas no mundo. Sendo assim, os traficantes têm procurado novos meios para mascarar o teste preliminar (colorimétrico) atualmente utilizado. Este trabalho descreve uma metodologia para detecção de delta-9-tetraidrocanabinol (Δ9-THC) por voltametria de onda quadrada (SWV) em meio orgânico N,N-dimetilformam

3. Correlação entre densidade de fibras nervosas em biópsia de pele e teste de quantificação da sensibilidade térmica em pacientes com hanseníase
It is known that, in lesions of leprosy, loss of tactile sensitivity, mediated by thick myelinated A-beta type nerve fibers, is preceded by the loss of thermal sensitivity, mediated by thin myelinated A-delta type and thin unmyelinated C type thin fibers, which makes the evaluation of the thermal sensitivity of a suspicious lesion a fundamental criterion for

4. Espectroscopia de cavidade ressonante tipo Ring-DOWN supercontinuum resolvida no tempo para detecção de multicomponentes gasosos / Supercontinuum Cavity Ring-Down Spectroscopy For Simultaneous Detection Of Multicomponent Gases
In this work, we present a variation of the technique CRDS (Cavity Ring-Down Spectroscopy) to obtain simultaneously a multicomponent absorption spectrum in a broad visible range. This new approach uses the Supercontinuum (SC) spectrum (resulting from irradiation of nonlinear media by femtosecond lasers, or simply generated by compact sources) as a light sour

5. Aspectos epidemiológicos da infecção pelo vírus da hepatite c e coinfecções com os vírus b e delta no estado do Acre, Amazônia ocidental brasileira
Background. Viral hepatitis are leading complex public health issue worldwide,particularly chronic hepatitis B, C and D because of the risk for cirrhosis andhepatocellular carcinoma development. Amazon basin is for long recognized ashyperendemic for B and D virus but originally supposed to be indene for HCV, althoughits introduction into remote Amazon commun

6. DESENVOLVIMENTO DE MÉTODOS ANALÍTICOS ESPECTROLUMINESCENTES E ELETROFORÉTICOS PARA A DETERMINAÇÃO DE ALCALOIDES (BETA-CARBOLINAS, CAMPTOTECINA E DERIVADOS) DE INTERESSE FARMACOLÓGICO / DEVELOPMENT OF ANALYTICAL METHODS BASED ON LUMINESCENCE AND ELECTROPHORESIS FOR THE DETERMINATION OF ALKALOIDS (BETA-CARBOLINES, CAMPTOTHECIN AND DERIVATIVES) OF PHARMACOLOGICAL INTEREST
Analytical methods were developed for the selective determination of alkaloids of pharmacological interest. Aiming the selective determination of camptothecin (CPT) in irinotecan (CPT-11) or topotecan (TPT) based pharmaceutical formulations, two spectrofluorimetric methods and one electrophoretic method with absorciometic detection were proposed. The spectro

7. DESENVOLVIMENTO DE MÉTODOS ANALÍTICOS CROMATOGRÁFICOS, ESPECTROFLUORIMÉTRICOS E ELETROFORÉTICOS PARA A DETERMINAÇÃO DE AZAARENOS BÁSICOS EM QUEROSENE DE AVIAÇÃO / DEVELOPMENT OF ANALYTICAL METHODS BASED ON CHROMATOGRAPHY, FLUORESCENCE AND ELECTROPHORESIS FOR THE DETERMINATION OF BASIC AZAARENES IN JET FUEL SAMPLES
In this work, analytical methods were developed for the selective determination of basic azaarenes. Solid phase extraction (SPE) in combination with high performance liquid chromatography with fluorescence detection (HPLCFD) has been used for the sensitive method determination of six basic azaarenes (7,8-benzoquinoline - 78BQ, 7,9-dimethylbenz[c]acridine - 7

8. Tratamento de conflitos e detecção de deltas em atualização através de visões XML / Conflict resolution and difference detection in updates through XML views
A linguagem XML tem se tornado um padrão no intercâmbio de informações naWeb. No entanto, a maioria das organizações continua a armazenar seus dados em bancos de dados relacionais. Diante deste ambiente, surge a necessidade de se construir aplicações que permitam às empresas o intercâmbio de informações via XML, mas sem que estas empresas tenham

9. Investigation of a novel Bacillus thuringiensis toxin
The aim of the present work was to investigate the toxicity, biochemical characteristics, gene and protein contents, and the mechanism of action of toxins from the Brazilian Bacillus thuringiensis (Bt) strain S725. This strain has been reported as toxic against the cotton boll weevil (Anthonomus grandis), a severe pest of cotton crops in America, which is co

10. Standardization of the PCR technique for the detection of delta toxin in Staphylococcus spp.
Coagulase-negative staphylococci (CNS), components of the normal flora of neonates, have emerged as important opportunistic pathogens of nosocomial infections that occur in neonatal intensive care units. Some authors have reported the ability of some CNS strains, particularly Staphylococcus epidermidis, to produce a toxin similar to S. aureus delta toxin. Th

11. Detection of somatic mutations of the PIG-A gene in Brazilian patients with paroxysmal nocturnal hemoglobinuria
Paroxysmal nocturnal hemoglobinuria (PNH) is an acquired clonal syndrome characterized by intravascular hemolysis mediated by complement, thrombotic events and alterations in hematopoiesis. Basically, the molecular events which underlie the complexity of the syndrome consist of the absence of the glycosylphosphatidylinositol (GPI) anchor as a consequence of

12. Detecção e diagnostico de falhas em sistemas de processos quimicos. Importancia do conhecimento de estados intermediarios de processos dinamicos. Desenvolvimento de uma metodologia baseada em redes neurais
Artificial Neural Networks (ANN) have demonstrated excellent performance in automatic fault detection and diagnosis in many engineering applications. The great problem when using neural networks, is that neural networks perform only as robustly as the data from which they are trained. This means that is necessary to use as much data as possible in order to c
