Fracture probability and fragment size distribution of fired Iron ore pellets by impact

Luís Marcelo Tavares, Pedro P. Cavalcanti, Rodrigo M. de Carvalho, Marcus W. da Silveira, more

Powder Technology > 2018 > 336 > C > 546-554

Degradation that results from transportation and handling can have an important economic impact in steelmaking materials, given the lower value of the finer material that is generated. In spite of their higher strength when compared to lump iron ores, fired iron ore pellets also undergo some degradation, which increases with severity of the handling operations that occur from the pelletizing plant...

Fluid hydration to prevent post-ERCP pancreatitis in average- to high-risk patients receiving prophylactic rectal NSAIDs (FLUYT trial): study protocol for a randomized controlled trial

Xavier J. N. M. Smeets, David W. da Costa, Paul Fockens, Chris J. J. Mulder, more

Trials > 2018 > 19 > 1 > 1-9

Background Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is the most common complication of ERCP and may run a severe course. Evidence suggests that vigorous periprocedural hydration can prevent PEP, but studies to date have significant methodological drawbacks. Importantly, evidence for its added value in patients already receiving prophylactic rectal non-steroidal...

Last glacial and Holocene stable isotope record of fossil dripwater from subtropical Brazil based on analysis of fluid inclusions in stalagmites

Christian Millo, Nicolás M. Strikis, Hubert B. Vonhof, Michael Deininger, more

Chemical Geology > 2017 > 468 > C > 84-96

The stable isotope composition of fossil dripwater preserved in stalagmites fluid inclusions is a promising tool to reconstruct paleopluviosity in the tropics and subtropics. Here we present δD and δ¹⁸O records of fossil dripwater from two stalagmites collected in Botuverá Cave (subtropical Brazil), covering the last glacial period and the Holocene. The observed millennial-scale variability of fossil...

Sequential state inference of engineering systems through the particle move-reweighting algorithm

R. Marques, W. Da Silva, R. Hoffmann, J. Dutra, more

Computational and Applied Mathematics > 2018 > 37 > 1 > 220-236

Intractable sequential inference arises in several applications in the physical engineering process. One of the most successful and efficient stochastic simulation techniques that is appropriate to perform the Bayesian inference (inversion decision) in complex dynamic models is the sequential Monte Carlo (SMC) methods. Although, these methods have become widely accepted among researchers and practitioners,...

Cost‐effectiveness of same‐admission versus interval cholecystectomy after mild gallstone pancreatitis in the PONCHO trial

D. W. da Costa, L. M. Dijksman, S. A. Bouwense, N. J. Schepers, more

British Journal of Surgery > 103 > 12 > 1695 - 1703

Background Same‐admission cholecystectomy is indicated after gallstone pancreatitis to reduce the risk of recurrent disease or other gallstone‐related complications, but its impact on overall costs is unclear. This study analysed the cost‐effectiveness of same‐admission versus interval cholecystectomy after mild gallstone pancreatitis. Methods In a multicentre RCT (Pancreatitis of biliary Origin:...

Ulceration in bladder cancer associates with extravesical disease, independent of cell cycle, or hypoxia pathways status

Luciana Schultz, Samuel J.T. Spagnul, Gilcy R. Damm, Isabela W. da Cunha, more

Urologic Oncology: Seminars and Original Investigations > 2016 > 34 > 11 > 484.e9-484.e17

Ulceration is common in bladder tumors, but its prognostic role, although intuitive, is not established. We aim to explore the presence of gross ulceration and its relationship with other morphological and biological features classically associated with extravesical disease, in patients submitted to radical cystectomy.Tumor size and morphology were noted on 101 cystectomy patients (2000–2010). Papillary,...

Effect of the thickness reduction on the structural, surface and magnetic properties of α-Fe2O3 thin films

Fermin F.H. Aragón, José D. Ardisson, Juan C.R. Aquino, Ismael Gonzalez, more

Thin Solid Films > 2016 > 607 > C > 50-54

Hematite (α-Fe₂O₃) polycrystalline thin films of different thicknesses were produced by thermal oxidation in air atmosphere from Fe metallic thin-films deposited by radio frequency (RF) sputtering technique. X-ray diffraction (XRD) patterns confirm the formation of hematite phase in all samples and indicate that the mean grain size decreases as the film thickness becomes thinner. Conversion electron...

Liver injury attenuation by curcumin in a rat NASH model: an Nrf2 activation-mediated effect?

B. Li, L. Wang, Q. Lu, W. Da

Irish Journal of Medical Science ( 01971 -) > 2016 > 185 > 1 > 93-100

Aim Nuclear factor-erythroid 2-related factor-2 (Nrf2) acts as a defense system in the development of nonalcoholic steatohepatitis (NASH). Curcumin is a phenolic compound with lipid regulatory, anti-oxidative, anti-inflammatory and anti-tumorigenic properties that is beneficial in defending against NASH and was recently proved to be an Nrf2 activator. The aim of this study was to evaluate whether...

Issues related to waste sewage sludge drying under superheated steam

I. Hamawand, W. da Silva Pereira, F. Eberhard, D. L. Antille

Polish Journal of Chemical Technology > 2015 > Vol. 17, nr 4 > 5--14

Sewage sludge was dried in a rotary drum dryer under superheated steam. Particle size and moisture content were shown to have significant influences on sticking and agglomeration of the materials. Pouring partially dried sludge (70–80% moisture content, wet basis) directly into the screw feeder of the drum dryer resulted in a significant sticking to the surface of the drum and the final particle size...

2015 IEEE PES Innovative Smart Grid Technologies Latin America (ISGT LATAM) > 411 - 416

2015 IEEE PES Innovative Smart Grid Technologies Latin America (ISGT LATAM)

This paper presents a new technical approach based on mixed integer nonlinear mathematical formulation for the automatic restoration problem of distribution networks with distributed generation (DG), using node-depth encoding (NDE) and tabu search (TS) metaheuristic. The mathematical model considers the possibility of DG isolated operation and two principal objectives of restoration problem, that...

Same-admission versus interval cholecystectomy for mild gallstone pancreatitis (PONCHO): a multicentre randomised controlled trial

David W da Costa, Stefan A Bouwense, Nicolien J Schepers, Marc G Besselink, more

The Lancet > 2015 > 386 > 10000 > 1261-1268

In patients with mild gallstone pancreatitis, cholecystectomy during the same hospital admission might reduce the risk of recurrent gallstone-related complications, compared with the more commonly used strategy of interval cholecystectomy. However, evidence to support same-admission cholecystectomy is poor, and concerns exist about an increased risk of cholecystectomy-related complications with this...

SOD2 immunoexpression predicts lymph node metastasis in penile cancer

Lara Termini, José H Fregnani, Enrique Boccardo, Walter H da Costa, more

BMC Clinical Pathology > 2015 > 15 > 1 > 1-8

Background Superoxide dismutase-2 (SOD2) is considered one of the most important antioxidant enzymes that regulate cellular redox state in normal and tumorigenic cells. Overexpression of this enzyme in lung, gastric, colorectal, breast cancer and cervical cancer malignant tumors has been observed. Its relationship with inguinal lymph node metastasis in penile cancer is unknown. Methods ...

Measurement of the electron structure function F2e at LEP energies

J. Abdallah, P. Abreu, W. Adam, P. Adzic, more

Physics Letters B > 2014 > 737 > C > 39-47

The hadronic part of the electron structure function F2e has been measured for the first time, using e+e− data collected by the DELPHI experiment at LEP, at centre-of-mass energies of s=91.2–209.5 GeV. The data analysis is simpler than that of the measurement of the photon structure function. The electron structure function F2e data are compared to predictions of phenomenological models based on the...

Modified glassy carbon electrode with AuNPs using cis-[RuCl(dppb)(bipy)(4-vpy)]+ as crossed linking agent

Vanessa F. Ferreira, Cássio R.A. Do Prado, Carolina M. Rodrigues, Larissa Otubo, more

Polyhedron > 2014 > 78 > Complete > 46-53

This work links aspects of non-covalent interaction among gold nanoparticles (AuNPs) and ruthenium complexes, which were used to modify the surface of the glassy carbon electrode (GCE), without the necessity of a sulfur substrate with a covalent bond between gold–sulfur (Au–S), to keep the AuNPs onto the surface of the electrode. The AuNPs were synthesized by the method of encapsulation by citrate...
