Effect of additives on the cloud points of aqueous solutions of ethylene oxide-propylene oxide-ethylene oxide block copolymers
(Academic Press IncSan DiegoEUA, 1998)
Nanostructured epoxies based on the self-assembly of block copolymers: A new miscible block that can be tailored to different epoxy formulations
(American Chemical Society, 2007-02)
Nanostructured thermosets may be obtained by the self-assembly of amphiphilic block copolymers (BCP) in a reactive solvent and fixation of the resulting morphologies by the cross-linking reaction. Nanostructuration requires ...
Structure and texture filling-in of missing image blocks in wireless transmission and compression
(UR. FING, 2002)
An approach for filling-in blocks of missing data in wireless image transmission is presented in this paper. When compression algorithms such as JPEG are used as part of the wireless transmission process, images are first ...

(Elsevier, 2020)
Study objective: Comparison of ultrasound-guided lumbar plexus block (LPB) and suprainguinal fascia iliaca block (SIFIB) in patients undergoing total hip arthroplasty (THA).
Design: Randomized equivalence trial.
Setting: ...
Block copolymers in the synthesis of gold nanoparticles. Two new approaches: Copolymer aggregates as reductants and stabilizers and simultaneous formation of copolymer aggregates and gold nanoparticles
(John Wiley and Sons Inc., 2014)
© 2014 Wiley Periodicals, Inc.In this article, innovative applications of amphiphilic triblock and pentablock copolymers in the synthesis of gold nanoparticles are reported. The synthesis of gold nanoparticles is performed ...
Acceptability of a herd immunity-focused, transmission-blocking malaria vaccine in malaria-endemic communities in the Peruvian Amazon: an exploratory study
(BioMed Central, 2018)
BACKGROUND: A transmission-blocking vaccine (TBV) to prevent malaria-infected humans from infecting mosquitoes has been increasingly considered as a tool for malaria control and elimination. This study tested the hypothesis ...
Perinatal outcome of fetal atrioventricular block - One-hundred-sixteen cases from a single institution
(LIPPINCOTT WILLIAMS & WILKINS, 2008)
Background-Fetal atrioventricular (AV) block is an uncommon lesion with significant mortality. Because of the rarity of this disorder, the natural course, extensive evaluation of untreated fetuses, and late follow-up remain ...
Grinding performance by applying MQL technique: an approach of the wheel cleaning jet compared with wheel cleaning Teflon and Alumina block
(Springer, 2020-04-27)
Characterized by the high heat generation, grinding has great difficulty in dry machining. As an alternative, it is proposed to apply abundant cutting fluid (conventional method) or a minimum amount of lubrication, which ...
