FORMAÇÃO DE PROFESSORES: A IMAGEM DO MATRIX COMO RECURSO EDUCATIVO
Authors: Barros Daniela Melaré Vieira 
Published: July 2014

A imagem na atualidade transformou-se numa potencialização de informação maior do que a linguagem escrita. Na seqüência, a informação transformou-se numa hipermídia de amplos e diversificados contextos. Essa hipermídia trouxe, a partir da indústria da cultura de massa, imagens reais ou, melhor dizendo, simuladas, que condicionaram a percepção humana à recepção de imagens sem muitas reflexões ou análises críticas. Nesta construção entre imagem e informação, como repensar as informações da linguagem no processo de ensino e aprendizagem? Pode-se afirmar que a falta de interesse dos aprendizes, a motivação e as dificuldades de assimilação, bem como as reflexões aprofundadas nos conhecimentos e informações, advêm dessa reestruturação da imagem e da informação no contexto atual. Pensar nessa perspectiva significa ter como referência a imagem que aqui será abordada com o filme Matrix e seus elementos. Para tanto os fundamentos teóricos para esta análise são Lévy (1999), Moran (2000) e Irwin (2003). O uso do Matrix tem como meta análises transdisciplinares que auxiliem o aluno a ler e compreender a conexão das tecnologias com o mundo atual. O uso do filme nos possibilita desenvolver os conteúdos conceituais das tecnologias em sua dimensão filosófica e científica.
Emotion, Cognition, and the Value of Literature: The Case of Nietzsche's Genealogy
Authors: Aumann Antony 
Published: July 2014

ABSTRACT
One striking feature of On the Genealogy of Morals is how it is written. Nietzsche employs a literary style that provokes his readers' emotions. In Beyond Selflessness, Christopher Janaway argues that such a literary approach is integral to Nietzsche's philosophical goals. Feeling the emotions Nietzsche's style arouses is necessary for understanding the views he defends. I argue that Janaway's position is mistaken. The evidence at our disposal fails to establish that emotion is ever necessary for cognition. However, I maintain that we do have good evidence for a slightly weaker claim. The emotionally sensitive person is epistemically better off than the cold and dispassionate person. There are some truths he or she will be more likely to believe and will have better reasons for believing. I conclude that Janaway is right to defend the philosophical importance of Nietzsche's literary writing style. His error is simply that he overstates the case.

Quantum-chemical ab initio and time-dependent density functional theory (TD-DFT) calculations employing various basis sets were used to elucidate the spatial as well as the electronic structure of C5H5Al () and C5H5Ga (2) (ala- and galabenzene). The lowest closed shell singlet states of both compounds were found to have a non-planar structure of C
S symmetry with C-X-C bond angles of about 116° (MP2/6-311++G**) and 125° (CCSD/aug-cc-pVDZ). At approximately 103°, the corresponding angles of the lowest triplets are significantly smaller. The lowest triplet state of alabenzene is also non-planar (C
S) at the MP2 level while optimization with the CCSD and the CASPT2 method resulted in planar structures with C
2v symmetry. The corresponding state of galabenzene has C
2v symmetry at all levels of optimization. The relative stability of the lowest closed shell singlet and the lowest triplet (ΔE(T
1-S
0)) state is small and its sign even strongly method-dependent. However, according to the highest levels of theory applied in this study the singlet states of both molecules are slightly lower in energy than the corresponding triplets with singlet/triplet gaps between about 0.5 and 5.8 kcal/mol in favour of the singlet states. Most of the applied methods give a slightly smaller splitting for ala- than for galabenzene. Independent of the applied method (TD-DFT/CAM-B3LYP/6-311++G(3df,3pd)//MP2/6- 311++G** or SAC-CI/6-31++G(3df,3pd)//MP2/6-311++G**), the general shape of the calculated UV/VIS spectral curves are quite similar for the lowest singlet states of ala- and galabenzene, and the same applies to the spectra of the normal modes. The calculated UV/VIS spectra of C5H5Al and C5H5Ga are featured by long wavelength bands of moderate intensity around 900 nm at the TD-DFT and between 1300 and 1500 nm at the SAC-CI level. According to both methods these bands are predominantly due to HOMO(π)→LUMO(σ*) transitions. The results of isodesmic bond separation reactions for the singlet states indicate some degree of stabilization due to delocalization in both of the title compounds. With our best values between 29 and 32 kcal/mol this stabilization appears to be only slightly less than the previously reported value for borabenzene (∼38 kcal/mol).

Abstract
A study was carried out to determine the efficacy of the Soleris® Direct Yeast and Mold (DYM) automated growth-based method for semiquantitative detection of yeast and mold in a variety of food products. A probability of detection (POD) statistical model was used to compare Soleris results at multiple test thresholds (dilutions) with plate counts determined using the U.S. Food and Drug Administration Bacteriological Analytical Manual, Chapter 18, dilution plating procedure. Fourteen naturally contaminated food products were tested, with Soleris testing performed at three or more threshold levels for each food. Using the POD model, the majority of Soleris test results were in statistical agreement with the reference plating procedures. The exceptions included a single threshold level in yogurt, black pepper, dried fruit, and dry pet food, and two levels in nonfat dry milk and saw palmetto powder. In all but one of these instances, the exception being pet food, the statistical disagreement was due to Soleris estimating a higher level of contamination than the reference method. Results of ruggedness testing showed that the Soleris method produced accurate results even when significant variances in a critical operating parameter, incubation temperature, were introduced. Results of the internal and independent laboratory validation studies showed that the Soleris DYM method can be used as an accurate alternative to conventional dilution plating procedures for evaluation of yeast and mold counts at threshold levels, while saving as much as 72 h in analysis time.
Re-evaluation of the Retention Time Prediction “Polarity” Model in the Context of the Development of a Stationary Phase Variable
Authors: Karpiński Adam , Mikiciuk-Olasik Elżbieta , Szymański Paweł 
Published: July 2014

Abstract
The Abraham–Carr retention time prediction model was reviewed and developed in the context of the introduction of a new stationary phase variable. The new variable consists of a binary mixture dielectric constant and a stationary phase descriptor that was derived from the Snyder–Dolan column descriptors theory. In this work, data reported by Torres–Lapasio were investigated (in-silico) in the context of the linearity behavior of the Abraham–Carr theorem logk = ƒ(PNm). This proposed model has been replaced by several experiments that have shown that the stationary phase constant PNS, which is represented by a variable, does not require laboratory experiments. The new model, which contains stationary and mobile phase variables, shows an improved correlation for the majority of the Torres–Lapasio compounds between logk and ΔPN (mobile and stationary phase variables expression). The discussion regarding the model's behavior in the presence of secondary interactions led to research using a polar column and “bulky” compounds as reported by Szymański. Newly developed tacrine 4-fluorobenzoic acid derivatives, potential drugs in Alzheimer's disease treatment, are homologs and were found problematic to separate using regular C18 sorbent. The obtained results show that in the range of 30–70% acetonitrile, a single retention model using Agilent Zorbax SB-cyano sorbent is present, which is confirmed by two investigated models (R2 &gt; 0.95).

Abstract
The SASTM Molecular Tests method for detection of Salmonella spp. in various food matrixes has been certified by the AOAC Research Institute and designated Performance Tested MethodSM No. 021202. The current method modification includes the optional immunomagnetic separation (IMS) to enrich the bacteria as well as optional visual fluorescence readout without the use of a turbidimeter. The modifications were validated against the U.S. Department of Agriculture/Food Safety and Inspection Service Microbiology Laboratory Guidebook (MLG) and the U.S. Food and Drug Administration Bacteriological Analytical Manual (BAM) reference methods. Food matrixes (chicken carcass rinse, beef trim, and spinach) were inoculated with low levels of Salmonella spp. (0.2–2 CFU/test portion) to generate fractional positives (5–15) in 20 inoculated samples. Samples were enriched with SAS Enrichment medium and incubated at 42 ± 1°C. Enrichments were tested directly and subjected to anti-Salmonella IMS prior to the SAS Molecular Tests. Results were determined via visual fluorescence and via turbidity using a turbidimeter. All replicates were confirmed using the MLG or BAM reference method procedures, regardless of presumptive result. The SAS Molecular Tests Salmonella Detection modified methods were determined to be equivalent to the reference methods for the detection of Salmonella in chicken carcass rinse, beef trim, and fresh spinach. The inclusion of IMS in the modified method improved the detection rate of Salmonella in chicken carcass rinses and spinach. The optional use of visual fluorescent reagent and heat block either with IMS or without IMS produced results that were comparable to the results obtained from using a real-time turbidimeter.

Abstract

Human induced pluripotent stem cell (hiPSC) lines have a great potential for therapeutics because customized cells and organs can be induced from such cells. Assessment of the residual reprogramming factors after the generation of hiPSC lines is required, but an ideal system has been lacking. Here, we generated hiPSC lines from normal human dermal fibroblasts with piggyBac transposon bearing reprogramming transgenes followed by removal of the transposon by the transposase. Under this condition, we compared the phenotypes of transgene-residual and -free hiPSCs of the same genetic background. The transgene-residual hiPSCs, in which the transcription levels of the reprogramming transgenes were eventually suppressed, were quite similar to the transgene-free hiPSCs in a pluripotent state. However, after differentiation into keratinocytes, clear differences were observed. Morphological, functional, and molecular analyses including single-cell gene expression profiling revealed that keratinocytes from transgene-free hiPSC lines were more similar to normal human keratinocytes than those from transgene-residual hiPSC lines, which may be partly explained by reactivation of residual transgenes upon induction of keratinocyte differentiation. These results suggest that transgene-free hiPSC lines should be chosen for therapeutic purposes.
Son organisé, partition sonore, ordre musical : la pensée et la pratique cinématographiques d’Edgard Varèse et de Michel Fano
Authors: Dallaire Frédéric 
Published: July 2014

Cet article suit le développement d’une sensibilité musicale au cinéma à travers les écrits et les oeuvres d’Edgard Varèse et de Michel Fano. Varèse pose les bases d’un nouveau paradigme en décrivant les transformations de la musique au contact des images et en inscrivant les sons dans le dispositif « d’enregistrement/montage/diffusion cinématographique ». Les notions de son organisé et de partition sonore sont pour lui les outils qui permettent de penser et de travailler la musicalité filmique. À partir des années 60, Fano s’inspire des idées de Varèse et les éprouve en composant plusieurs partitions sonores (notamment pour les films d’Alain Robbe-Grillet). En intégrant tous les sons (parole, bruit, musique) dans sa démarche musicale, le compositeur produit une écoute et une conscience singulière de la musique au cinéma : les sons (et les images) se divisent en formants, et le compositeur met en relation ces éléments afin de produire des affects musicaux et signifiants. Les notions de continuum sonore, d’ordre musical et de formant dynamisent et enrichissent alors le champ compositionnel imaginé par Varèse. En définitive, la réflexion sur le son organisé au cinéma a pour fondement le processus de construction réciproque du dispositif sonore, de la pensée compositionnelle cinématographique et des formes esthétiques. Le compositeur travaille à la surface d’un plan continu, la partition sonore, dont il doit façonner les matériaux et organiser les interactions. Le compositeur met en relation les sons et érige un « réseau », un « carrefour », un complexe audio-visuel constitué de formants. Cet espace sonore processuel fait de tensions, de consonances, de dissonances, de confrontations énergétiques et sémantiques modifie durablement notre façon de penser la musique au cinéma.

Published: August 2024

AbstractSolid oxide cells (SOCs) hold considerable promise as devices for efficient, reversible conversion between chemical and electrical energy, facilitating a global shift toward renewable energy. Electrode performance is critical for SOC efficiency and durability and composite materials are key to developing high‐performance electrode catalysts. However, conventional mechanical mixing and infiltration methods often lead to large particle sizes, uneven distribution, and weak interfacial interactions, thus limiting electrochemical activity and longevity. Recent advancements have produced powerful new strategies for creating composite materials. These include metal exsolution and oxide segregation for fuel electrodes and one‐pot synthesis, segregation, phase reaction, and dynamic cation exchange for air electrodes. These techniques yield highly active, uniform nano‐catalysts and robust multi–phase interfacial contacts, significantly improving electrochemical activity and durability. This work reviews these advanced strategies and their applications in SOCs. It provides valuable insights for designing and optimizing SOC catalyst materials, accelerating the development of this vital energy conversion technology.

AbstractRoom‐temperature liquid metal droplets (LMDs) are a promising material for various applications in soft robotics, active droplets, and biomedical devices. However, controllable and high‐throughput production of LMDs remains challenging due to their high surface tension and density. Here, a novel strategy is presented to produce LMDs by combining electric field‐induced electrocapillary flow with an external flow field. The basic mechanism is that the electrocapillary flow induced at the LMD/electrolyte interface forms a vortex ring in the electrolyte, creating a hurricane‐like effect in the tube, which in turn causes the liquid metal to deform and eventually pinch off into small droplets. It is demonstrated that droplet size and generation frequency can be controlled precisely by adjusting the applied electric current, flow rate, and surfactant concentration, establishing a relationship between radius and experimental parameters through dimensionless analysis. More importantly, this strategy can handle pendant droplets and facilitate programmable droplet patterning. Leveraging established relationships, flexible control over droplet size and spacing during patterning is attained. Furthermore, an iontronic pressure‐sensitive device based on LMDs and hydrogel is developed to showcase the versatility of the approach. This technique opens up new opportunities for fabricating soft circuits, composite materials, and other functional devices with LMDs.

AbstractExploring photothermal nanomaterials is essential for new energy and biomedical applications; however, preparing materials with intense absorption, highly efficient light‐to‐heat conversion, and enhanced photostability still faces the enduring challenge. Herein, the study synthesizes atomic‐thin (≈1.6 nm) 2D copper sulfide (AT‐CuS) plasmonic nanocrystals and find its extraordinary photothermal conversion efficiency (PCE) reaching up to 94.3% at the second near‐infrared (NIR‐II) window. Photophysical mechanism studies reveal that the strong localized surface plasmon resonance (LSPR) and out‐of‐plane size effect of AT‐CuS induce strong optical absorption and non‐equilibrium carrier scattering, resulting in a significant carrier‐phonon coupling (7.18 × 1017 J K−1 s−1 m−3), ultimately enhancing the heat generation. Such a photothermal nanomaterial demonstrates at leastmes stronger NIR‐II photoacoustic (PA) signal intensity than that of most commonly used miniature gold nanorods, together with greater biocompatibility and photo‐/thermal‐stability, enabling noninvasive PA imaging of brain microvascular in living animals. This work provides an insight into the rational exploration of superb NIR‐II photothermal and photoacoustic agents for future practical utilizations.

Published: August 2024

AbstractGallium‐based liquid metals with outstanding electrical conductivity and fluidity are widely used in wearable electronics for wireless communication, human–machine interaction, and smart textiles. However, their fluidity makes them easily leak from the embedded conductive circuits under repeatable stretching, mechanical damage, or exposure to acidic and alkaline environments, limiting their reliability in practical use. Here, highly stable LM–polymer composites are shown with the ability to endure significant mechanical or chemical stresses, maintaining low resistance changes (R/R0 = 3.3 and 2.4) after 10 times of standard washing and 24 h of storage in corrosive solutions. The use of fluoropolymer, providing robust interfacial binding with the gallium oxide layer, effectively serves as a barrier layer to withstand mechanical and chemical damage through the synergistic effect of adaptive dipole–dipole interactions among composites and enhanced hydrophobicity. The as‐prepared composites can be readily hot pressed onto commercial fabrics to develop electronic textiles with outstanding conductivity (10214 S m−1), high air permeability (148.6 mm s−1), and moisture permeability (30.3 g m−2). Taking advantage of their excellent stability and permeability, e‐textiles are demonstrated as washable thermal therapy patches and skin‐interfaced electrodes for epidermal biopotential recording.

AbstractElectrocatalytic N2 reduction reaction (eNRR) has been deemed as an alternative approach to the Haber‐Bosch (H‐B) process for ammonia (NH3) production, but it remains a huge challenge. Here jet plasma oxidation of N2 is reported in air into NOx and subsequently NO2− coupling with electrochemical NO2− reduction reaction (pN2─eNO2−RR) over PdNi alloying nanoparticles on N‐doped carbon nanotubes (PdNi/N‐CNTs) for NH3 synthesis. The results demonstrate that the jet plasma reactor possesses excellent gas reforming capacity to achieve the largest NO2− yield rate of 30.46 mmol h−1 with a low energy consumption of 2.66 kWh molN−1. For subsequent eNO2−RR, PdNi/N‐CNTs can afford an NH3 yield of 34.96 mg h−1 mgcat.−1 and a faradaic efficiency (FE) of 98.21% at −0.38 and 0.02 V (vs RHE), respectively. In situ spectroscopic characterizations combined with theoretical calculations unveil that PdNi/N‐CNTs provide Pd and Ni dual active sites, enabling NO2− activation on the Ni site and active H* provision on the Pd site to facilitate eNO2−RR. A cascade pN2‐eNO2−RR system is constructed for sustainable NH3 production, achieving a stable NH3 yield rate of 25.56 mmol h−1, an average FE >85%, as well as NOx to NH3 conversion efficiency of 44.62% at constant ampere‐level current with finally collection of gram‐level (NH4) 2SO4 product.

AbstractThe precise manipulation of the porous structure of the nanofiltration membrane is critical for unlocking enhanced separation efficiencies across various liquids and solutes. Ultrathin films of crosslinked macrocycles, specifically cyclodextrins (CDs), have drawn considerable attention in this area owing to their ability to facilitate precise molecular separation with high liquid permeance for both polar and non‐polar liquids, resembling Janus membranes. However, the functional role of the intrinsic cavity of CD in liquid transport remains inadequately understood, demanding immediate attention in designing nanofiltration membranes. Here, the synthesis of polyester nanofilms derived from crosslinked β‐CD, demonstrating remarkable Na2SO4 rejection (≈92 – 99.5%), high water permeance (≈4.4 – 37.4 Lm−2h−1bar−1), extremely low hexane permeance (<1 Lm−2h−1bar−1), and extremely high ratio (α > 500) of permeances for polar and non‐polar liquids, is reported. Molecular simulations support the findings, indicating that neither the polar nor the non‐polar liquids flow through the β‐CD cavity in the nanofilm. Instead, liquid transport predominantly occurs through the 2.2 nm hydrophilic aggregate pores. This challenges the presumed functional role of macrocyclic cavities in liquid transport and raises questions about the existence of the Janus structure in nanofiltration membranes produced from the macrocyclic monomers.
