1. Bond strength of a calcium silicate-based sealer tested in bulk or with different main core materials
The aim of this study was to evaluate the influence of a calcium silicate-based sealer (iRoot SP), with or without a core material, on bond strength to radicular dentin, in comparison with various contemporary root filling systems. Root canals of freshly extracted single-rooted teeth (n = 60) were instrumented using rotary instruments. The roots were randoml

2. Prevalence, risk factors and genotypes of hepatitis B infection among HIV-infected patients in the State of MS, Central Brazil
Objectives: A cross-sectional study on prevalence of HBV and HDV infection, risk factors and genotype distribution of HBV infection was conducted among 848 HIV-infected patients in Mato Grosso do Sul, Central Brazil. Methods: Serum samples of 848 participants were tested for hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBc) and hep

3. Fast test for assessing the susceptibility of Mycobacterium tuberculosis to isoniazid and rifampin by real-time PCR
Mycobacterium tuberculosis is the bacterium that causes tuberculosis (TB), a leading cause of death from infectious disease worldwide. Rapid diagnosis of resistant strains is important for the control of TB. Real-time polymerase chain reaction (RT-PCR) assays may detect all of the mutations that occur in the M. tuberculosis 81-bp core region of the rpoB gene

4. Aplicação de métodos não destrutivos para qualificação de combustíveis tipo dispersão de U308-Al e U3Si2-Al no reator IEA-R1 / Application of non-destructive methods for qualification of the U3O8-Al and U3Si2-Al dispersion fuels in the IEA-R1 Reactor
IPEN/CNEN-SP manufactures fuels to be used in its nuclear research reactor the IEA-R1. To qualify those fuels, it is necessary to check if they have a good performance under irradiation. As Brazil doesnt have nuclear research reactors with high neutron fluxes, or suitable hot cells for carrying out post-irradiation examination of nuclear fuels, IPEN/CNEN-SP

5. Study on the usability evaluation of prosthetic leg products based on ergonomics
The prosthetic leg (PL) is a typical human-machine system in which the dynamic interaction between the human body and PL (machine) determines a high requirement of ergonomics design for PL and consequently needs to consider an indicator of usability indicating the performance of gait biomechanics. How to evaluate the indexes of usability for PL products is c

6. Constraint-driven test scheduling for NoC-based systems
On-chip integrated network, the so-called networkon- chip (NoC), is becoming a promising communication paradigm for the next-generation embedded core-based system chips. The reuse of the on-chip network as test access mechanism has been recently proposed to handle the growing complexity of testing NoC-based systems. However, the NoC reuse is limited by the o

7. In silico analysis of alpha1-antitrypsin variants: the effects of a novel mutation
Alpha1-antitrypsin (AAT) is a highly polymorphic protein with more than 120 variants that are classified as normal (normal protein secretion), deficient (reduced circulating AAT level caused by defective secretion) or null (no protein secretion). Alpha1-antitrypsin deficiency, one of the most common genetic disorders, predisposes adults to pulmonary emphysem

8. Análise mecânica de retentores intra-radiculares / Mechanical analysis of endodontic post
The fiber-reinforcement composite (FRC) posts introduced the new concept of restorative system, in which the various components of the reconstruction: post, cement, filling material and dentin have now become a complex mechanically homogeneous. The knowledge of the structure, composition and physical properties of these fiber posts systems is important in or

9. A straightforward multiallelic significance test for the Hardy-Weinberg equilibrium law
Much forensic inference based upon DNA evidence is made assuming Hardy-Weinberg Equilibrium (HWE) for the genetic loci being used. Several statistical tests to detect and measure deviation from HWE have been devised, and their limitations become more obvious when testing for deviation within multiallelic DNA loci. The most popular methods-Chi-square and Like

10. Lógica e escalonamento de teste para sistemas com redes intra-chip baseadas em topologia de malha
Com o avanço da tecnologia de fabricação de chips o atraso em fios globais será maior que o atraso em portas lógicas. Além disso, fios globais longos são mais suscetíveis a problemas de integridade como crosstalk. Uma proposta recente de interconnecção global chamada redes intra-chip reduz essas limitações referentes a fios longos. Além dessas v

11. Influência da extensão e tipo de retentor intra-radicular na deformacão e resistência à fratura de dentes tratados endodonticamente
Studies concerning the effects of different post systems insertion depth on the strain and fracture resistance of endodontically treated teeth remain controversial. The purpose of this study was to investigate in vitro the effects of different post systems and depth of post insertion on the strain and fracture resistance of endodontically treated bovine inci

12. Estudo laboratorial dos danos causados pelo broqueamento e retificaÃÃo em corpos-de-prova testemunhos
It is normal in engineer practice to use core testing to determine the inplace compressive strength of concrete in a structure. Generally, cores are obtained to: Asses whether suspect concrete in a new structure complies with strength-based acceptance criteria; or determine in-place concrete strengths in an existing structure for the evaluation of structural
