    Abstract Plastic pollution poses a significant environmental challenge, necessitating the investigation of bioplastics with reduced end-of-life impact. This study systematically characterizes four promising bioplastics-polybutylene adipate terephthalate (PBAT), polybutylene succinate (PBS), poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), and polylactic acid (PLA). Through a comprehensive analysis of their chemical, thermal, and mechanical properties, we elucidate their structural intricacies, processing behaviors, and potential morphologies. Employing an environmentally friendly process utilizing supercritical carbon dioxide, we successfully produced porous materials with microcellular structures. PBAT, PBS, and PLA exhibit closed-cell morphologies, while PHBV presents open cells, reflecting their distinct overall properties. Notably, PBAT foam demonstrated an average porous area of 1030.86 μm

    Title translation Da reformulação discursiva a uma práxis da cultura científica: reflexões sobre a divulgação científica.
    Abstract This article addresses the main interpretations employed to understand science communication as a discursive reformulation of scientific discourse and as a genre of discourse of its own. Both these interpretations are analyzed critically, since the characteristics of the discourse of science communication are not equivalent to translation parameters nor compatible with criteria to understanding them as a component of their own discursive genre. Finally, it is emphasized that science communication should be understood as praxis objectified through activities developed amidst diverse spheres of ideological creation.

    Abstract Wireless communication technologies, particularly radio frequency (RF), have been widely explored for wearable electronics with secure and user-friendly information transmission. By exploiting the operational principle of chemically actuated resonant devices (CARDs) and the electrical response observed in chemiresistive materials, we propose a simple and hands-on alternative to design and manufacture RF tags that function as CARDs for wireless sensing of meat freshness. Specifically, the RF antennas were meticulously designed and fabricated by lithography onto a flexible substrate with conductive tape, and the RF signal was characterized in terms of amplitude and peak resonant frequency. Subsequently, a single-walled carbon nanotube (SWCNT)/MoS

    Abstract A total femoral approach for fenestrated-branched endovascular aortic aneurysm repair has been increasingly favored to minimize risks of aortic arch manipulation. We describe a novel technique to support the advancement of endovascular devices into a target vessel. Following catheterization of the intended target artery and deployment of the diameter-reducing ties, a Coda semi-compliant balloon (Cook Medical) is advanced and inflated immediately above the target artery. It is used as a support as the wire, catheter, or sheath "bounces" on the balloon, stabilizing the support wire to advance stent grafts, balloons, or sheaths into the downward renal or mesenteric vessels.

    Abstract Background and objectives: The preferred osmotic agent used for brain relaxation during craniotomies remains unclear, either mannitol (MAN) or hypertonic saline (HTS). Hence, we sought to compare these solutions in this population.
    Methods: MEDLINE, Embase, and Cochrane databases were systematically searched until August 02, 2023. Data were examined using the Mantel-Haenszel method and 95% CIs. Heterogeneity was assessed using I2 statistics. Meta-regression analysis was conducted to evaluate a possible link between Brain Relaxation Score and tumor volume. R, version 4.2.3, was used for statistical analysis.
    Results: A total of 16 randomized controlled trials and 1031 patients were included, of whom 631 (61%) underwent surgery for supratentorial tumor resection. Compared with MAN, HTS achieved better rates of brain relaxation (80% vs 71%; odds ratio [OR] 1.68; 95% CI 1.22-2.33; P = .001; I2 = 0%), which was also demonstrated in the subgroup analysis of patients with supratentorial brain tumor (78% vs 65%; OR 2.02; 95% CI 1.36-2.99; P = .0005; I2 = 0%); a minor number of patients requiring a second dose of osmotic agent (14% vs 28%; OR 0.43; 95% CI 0.27-0.69; P = .0003; I2 = 0%); a lower fluid intake (mean difference -475.9341 mL; 95% CI -818.8952 to -132.9730; P = .007; I2 = 88%); and lower urine output (mean difference -462.0941 mL; 95% CI -585.3020 to -338.8862; P = <.001; I2 = 96%). Hospital length of stay and focal neurological deficits did not reach a statistically significant difference between groups.
    Conclusion: In this updated meta-analysis, consistent results suggest that HTS is associated with more beneficial outcomes than MAN in patients undergoing craniotomy.

    Abstract Lutzomyia itambe sp. n. is described as a new species of neotropical cavernicolous phlebotomine sand fly based on specimens of males and females collected in the Gruta do Itambé, Altinópolis municipality, São Paulo State. In addition to this, we describe the male of Lutzomyia fonsecai (Costa Lima, 1932) collected near their type-locality in Bolivia. These descriptions are supported by illustrations that detail the morphological and morphometrical characteristics of the specimens. Lutzomyia itambe sp. n., L. fonsecai, along with L. dispar Martins & Silva, 1963, comprise the already named "Fonsecai complex". Both sex present parallel labial sutures, not forked, and males can be differentiated by parameral characters, while in females the distinction is made by characters of the palpi and spermathecae.

    Abstract The increasing demand for natural gas as a clean energy source has emphasized the need for efficient gas separation technologies. Metal-organic frameworks (MOFs) have emerged as a promising class of materials for gas separation, with anion-pillared MOFs (APMOFs) gaining attention for their fine-tuned pore design and shape/size selectivity. In this study, we investigate the dynamical and electronic properties of three APMOFs, SIFSIX-3-Cu, SIFSIX-2-Cu-i, and SIFSIX-2-Cu, for the separation of methane from ethane, ethene, propane, propene, and N using computational simulations. Our simulations employ Grand Canonical Monte Carlo (GCMC) and Molecular Dynamics (MD) techniques combined with Density Functional Theory (DFT) calculations. We find that that all three APMOFs exhibit promising separation capabilities for methane from propane and propene based on both thermodynamics and kinetics parameters. In addition, we use Noncovalent Interaction (NCI) analysis to investigate intermolecular interactions and find that the fluorine atoms in the MOF can polarize gas molecules and establish electrostatic interactions with hydrogen atoms in the molecule. Finally, we show that SIFSIX-2-Cu-i is a potential candidate for separating N
