Abstract In this study, we experimentally investigated the effects of chemically enhanced oil recovery methods containing hydrolyzed polyacrylamide (HPAM), surfactant–hydrolyzed (SHPAM), surfactant nanofluids (SNF), that is, coupled with carbon dioxide (CO 2 ) and water chase injection to measure in a sandstone reservoir. To proceed experiments, performed four flooding tests at simulated reserv...

Streptococcal inhibitor of complement (Sic) is a highly polymorphic extracellular protein made by serotype M1 group A Streptococcus strains that contributes to bacterial persistence in the mammalian upper respiratory tract. New variants of the Sic protein arise very rapidly by positive selection in human populations during M1 epidemics. The human antibody response to Sic was analyzed. Of 636 pe...

OBJECTIVES To determine the proportion of hospitals distributing free infant formula sample packs in 21 eastern states and the District of Columbia, to investigate any regional trends or timelines associated with discontinuation of formula pack distribution, and to catalog in 2 states the take-home items given to new mothers in addition to, or instead of, formula sample packs. DESIGN Data wer...

OBJECTIVES To compare Telfa with the Rapid Rhino Riemann nasal pack for use following endoscopic sinus surgery. DESIGN Prospective, randomized, double-blind, paired trial. SETTING Tertiary otolaryngology hospital. PARTICIPANTS Forty-five adult patients undergoing bilateral endoscopic sinus surgery for either chronic rhinosinusitis or nasal polyps. MAIN OUTCOME MEASURES A visual analogue...

A novel composite photocatalyst was synthesized by loading 5 wt % of platinum cobalt alloy on 3C-SiC nanowires and powder (Pt-Co-SiC) respectively via a simple polyol reduction method. Pt-Co-SiC were comprehensively characterized by SEM, HRTEM, XRD, PL, and XPS. The results indicated that Pt-Co nanoparticles in the size of 2-5 nm were dispersed homogeneously in the SiC nanowires and powders. Th...

BACKGROUND It is illegal in the EU for tobacco packaging to suggest that some cigarettes are safer than others. This study examined consumer perceptions of cigarette packs in the UK, including perceptions of 'plain packaging', in which colour and other design elements are removed, whilst retaining the brand name. METHODS 516 adult smokers and 806 youth aged 11-17 participated in an online sur...

BACKGROUND AND PURPOSE The aims of this study are to evaluate the risk factors for symptomatic ischemic complication (symptomatic ischemic complication [SIC], transient ischemic attack, or stroke) and microembolisms detected as MR diffusion-weighted imaging (MR-DWI)-positive (DWI(+)) lesions, and the relationship between DWI(+) and SIC after coiling of unruptured intracranial aneurysm. METHOD...

In recent years, much attention has been paid to the behavior of passive microwave sea ice concentration (SIC) products for marginal ice zones. Based on the definition of ice edges from ship observations, we identified pseudo-ship observations (PSO) and generated PSO ice edges from twelve cloud-free moderate-resolution imaging spectroradiometer (MODIS) images. Two SIC products of the advanced m...

Silicon carbide (SiC) is a particularly interesting species of presolar grain because it is known to form on the order of a hundred different polytypes in the laboratory, and the formation of a particular polytype is sensitive to growth conditions. Astronomical evidence for the formation of SiC in expanding circumstellar atmospheres of asymptotic giant branch (AGB) carbon stars is provided by i...

P ower electronics fabricated on the Silicon Carbide (SiC) platform can operate at higher temperatures, higher frequencies, and can delive higher circuit efficiencies as compared to traditional Si-based technologies [1]. The SiC transistors are especially attractive at 1.2 kV-10 kV ratings, particularly for medium and high-frequency applications [2]. Though SiC-based Schottky diodes were readil...
