Published: August 2024

Em vista dos muitos problemas ambientais que perpassam a humanidade, bem como da necessidade de se ater a um debate aguçado sobre o mesmo, é que o presente trabalho apresenta uma sequência didática para nortear tal compreensão, do mesmo modo que aponta para um caminho visando abordar o presente tema na educação. Assim, o foco se destina, em aprimorar uma discussão sobre o tema envolvendo aquecimento global, este que se caracteriza por inúmeras controvérsias que vão além do fenômeno em si, principalmente quando a atenção recai nas mudanças climáticas. Nesta perspectiva, o presente trabalho inclina-se para uma proposta em forma de sequência didática direcionada ao Ensino Médio buscando conscientizar sobre aspectos do fenômeno e auxiliar na formação crítica dos alunos quanto às informações difundidas por reportagens e a mídia em geral. Apresentada na disciplina Tópicos Atuais em Ciência e Tecnologia, ministrada em 2021 pelo Programa de Pós Graduação em Educação Científica e Tecnológica, da Universidade Federal de Santa Catarina, tal atividade foi desenvolvida como critério avaliativo da disciplina, cuja proposta consistia em nortear e aprofundar o debate sobre as mudanças climáticas e suas possíveis consequências, por meio da obra O que falta descobrir por John Maddox (1999).
Entropia em sistemas vivos: uma proposta de ensino de Física não tradicional
Authors: Moura Tiago Martins , Moura Cristiane de Carvalho Ferreira Lima 
Published: August 2024

Freire (1987) discorre sobre a necessidade de um ensino contextualizado e real que possa ser internalizado e, quando possível, utilizado em prol da sociedade. O conceito de entropia talvez seja um dos mais abstratos da Física, mas vital ao desenvolvimento da vida e da ciência. Visto essa necessidade, este artigo tem o objetivo de materializar uma proposta de ensino de Física não tradicional para a temática entropia em sistemas vivos para docentes aplicarem a discentes do ensino médio. Para tanto, utiliza-se de metodologia de natureza qualitativa, baseada em pesquisa bibliográfica. O referencial teórico constitui-se na proposição de situações problemáticas abertas que os alunos possam considerar de interesse, conforme Gil-Pérez (1993) e o livro "What Is Life? & Mind and Matter" (O que é a vida? O aspecto físico da célula viva) de Schrödinger (1944). Espera-se que esta proposta contribua para minimizar as dificuldades tanto no processo de ensino docente quanto no de aprendizagem discente, possibilitando novas perspectivas de ambos sobre a temática abordada, oportunizando um ensino de Física mais colaborativo, integrador, reflexivo de modo a viabilizar o desenvolvimento de competências e habilidades conforme preconizado na Base Nacional Comum Curricular (BNCC).

The aim of this study was to evaluate the effect of starvation and refeeding on the growth and food intake of gilthead seabream (Sparus aurata) and seabass (Dicentrarchus labrax) and on the growth and nitrogen uptake of glasswort (Salicornia europaea) in a polyculture aquaponic system under 12 ppt salinity for 75 days. Nine small-scale autonomous aquaponic systems were used, each containing 10 gilthead seabreams (average weight of 6.33 ± 0.73 g and average length of 5.73 ± 0.72 cm) and 10 seabasses (5.82 ± 0.77 g and 6.35 ± 0.45 cm), as well as five glasswort plants. Three fish feeding treatments were performed, a control (A), in which fish were fed daily until satiation, and two fasting treatments for 4 (B) and 7 days (C). Fish growth performance was significantly lower (p < 0.05) in the C treatment for both species compared to treatments A and B. Food consumption (FC) and feed conversion ratio (FCR) were significantly higher (p < 0.05) in treatment C. Glasswort growth performance was significantly higher in treatment C (p < 0.05). The results showed that the 4-day food-deprived fish were similar to the control fish by achieving partial compensatory growth. The more extended fasting period (7 days) resulted in significantly lower growth performance. The lipid and nitrogen retention levels in both species were significantly lower in food-deprived fish than in the control fish both before and during compensatory growth. The results suggest that a feeding schedule involving starvation–refeeding cycles is a promising feed management option for these species in polyculture aquaponic systems. The effect of food deprivation was also significantly beneficial (p < 0.05) for the growth performance of glasswort compared to the control treatment.

The ideal leaf area is essential for optimizing photosynthesis and resource distribution, which improves both yield and quality. Leaf retention is a cultural practice that involves maintaining definite number of leaves above the bunch to optimize photosynthetic efficiency and fruit quality. The experiment was conducted at the ICAR-National Research Centre for Grapes with different treatments of number of leaves above the bunch (10, 12, 14, 16 and >16 leaves). The parameters measured included leaf area, photosynthetic rate, stomatal conductance, transpiration rate, bunch weight, berry quality and raisin recovery. The results revealed that retaining 14 leaves above bunch with leaf area of 1066.33 cm2 resulted in maximum bunch weight (365.00 g), 50-berry weight (123.31 g), yield/vine (23.72 kg) and raisin recovery (26.54 %) while, minimum bunch weight (300.00 g), 50-berry weight (103.48 g), yield/vine (19.20 kg) and raisin recovery (24.35 %) were observed in more than16 leaves above the bunch. However, the leaf area/shoot (2888.00 cm2), leaf area/vine (69312.00 cm2), leaf area/bunch (1066.33 cm2) and leaf area/g berry weight (2.92 cm2/g) were found sufficient for high quality grape and raisin production in a vine spaced at 9 X 5 feet distance which was achieved through 14 leaves above the bunch in Manjari Kishmish grape. It is therefore recommended to maintain approximately 14 leaves above the bunch in Manjari Kishmish that will help to maximize photosynthetic efficiency, enhance leaf area distribution and support higher yield, raisin and better berry quality.
Propagation of Pi2 pulsations in a dipole model of the magnetosphere

Published: December 2014

AbstractLocalized fast flows that impinge on the inner magnetosphere from the plasma sheet are observed to oscillate on time scales of minutes. The compression ahead of these flows will launch fast mode waves, while the velocity shears at the edges of these flows directly excite shear Alfvén waves. These waves, which are coupled by gradients in the Alfvén speed, have been suggested as a source for the Pi1 and Pi2 waves that are observed at both high and low latitudes in the ionosphere. A new three‐dimensional simulation of the propagation of ULF waves in the dipolar region of the magnetosphere has been developed to study these coupled wave modes. This model includes a height‐resolved ionospheric conductivity so that ionospheric fields can be more realistically determined, as well as a direct calculation of ground magnetic fields to compare with ground magnetometers using an inductive ionosphere model. Results from this model show that a plasmaspheric resonance can be set up by waves with periods about 1 min and that field line resonances can be excited both inside and outside the plasmasphere. The use of the inductive ionosphere model leads to the conclusion that even a uniform Hall conductivity can break the dawn‐dusk symmetry of the convection pattern. Waves from a source at 10 Earth radii reach the ionosphere with time delays between high and low latitudes of tens of seconds, with implications for the timing of substorm phenomena observed by spacecraft and by ground magnetometers and radars.
Mesoscale eddies cases study at Xisha waters in the South China Sea in 2009/2010

Published: December 2014

AbstractAnalyzing the observed currents at Xisha (110.3899°E, 17.1038°N) during May 2009 to May 2010, it is found that the kinetic energy has significant mesoscale variability, and each peak responds to large positive/negative ocean surface current curl caused by mesoscale eddies. Compared the kinetic energy with the wind stress work and the pressure work, it is also found that the barotropic pressure work which is mainly contributed by the sea surface height (SSH) corresponding to the mesoscale eddies behaves like the kinetic energy. The contribution of the mesoscale eddies to the kinetic energy can be up to 90% sometimes and reach deep level every time. Using the satellite altimeter data, the paths of mesoscale eddies contributing to the kinetic energy variability are traced back. In the winter half of the year, the mesoscale eddies propagating along the northern South China Sea shelf or across the basin from the west of the Philippines toward Xisha arrive at Xisha, influencing the kinetic energy. In the summer half of the year, the mesoscale eddies are mainly from the south, which were shed from the Vietnam coast current. And the cause for eddy shedding may be related to the relaxation of the Ekman transport anomalies.
Atmospheric circulation processes contributing to a multidecadal variation in reconstructed and modeled Indian monsoon precipitation
Authors: Wu Qianru , Hu Qi 
Published: December 2014

AbstractAn analysis of the recently reconstructed gridded May–September total precipitation in the Indian monsoon region for the past half millennium discloses significant variations at multidecadal timescales. Meanwhile, paleo‐climate modeling outputs from the National Center for Atmospheric Research Community Climate System Model 4.0 show similar multidecadal variations in the monsoon precipitation. One of those variations at the frequency of 40–50 years per cycle is examined in this study. Major results show that this variation is a product of the processes in that the meridional gradient of the atmospheric enthalpy is strengthened by radiation loss in the high‐latitude and polar region. Driven by this gradient and associated baroclinicity in the atmosphere, more heat/energy is generated in the tropical and subtropical (monsoon) region and transported poleward. This transport relaxes the meridional enthalpy gradient and, subsequently, the need for heat production in the monsoon region. The multidecadal timescale of these processes results from atmospheric circulation‐radiation interactions and the inefficiency in generation of kinetic energy from the potential energy in the atmosphere to drive the eddies that transport heat poleward. This inefficiency creates a time delay between the meridional gradient of the enthalpy and the poleward transport. The monsoon precipitation variation lags that in the meridional gradient of enthalpy but leads that of the poleward heat transport. This phase relationship, and underlining chasing process by the transport of heat to the need for it driven by the meridional enthalpy gradient, sustains this multidecadal variation. This mechanism suggests that atmospheric circulation processes can contribute to multidecadal timescale variations. Interactions of these processes with other forcing, such as sea surface temperature or solar irradiance anomalies, can result in resonant or suppressed variations in the Indian monsoon precipitation.

Published: December 2014

AbstractA new Mars Global Ionosphere‐Thermosphere Model (M‐GITM) is presented that combines the terrestrial GITM framework with Mars fundamental physical parameters, ion‐neutral chemistry, and key radiative processes in order to capture the basic observed features of the thermal, compositional, and dynamical structure of the Mars atmosphere from the ground to the exosphere (0–250 km). Lower, middle, and upper atmosphere processes are included, based in part upon formulations used in previous lower and upper atmosphere Mars GCMs. This enables the M‐GITM code to be run for various seasonal, solar cycle, and dust conditions. M‐GITM validation studies have focused upon simulations for a range of solar and seasonal conditions. Key upper atmosphere measurements are selected for comparison to corresponding M‐GITM neutral temperatures and neutral‐ion densities. In addition, simulated lower atmosphere temperatures are compared with observations in order to provide a first‐order confirmation of a realistic lower atmosphere. M‐GITM captures solar cycle and seasonal trends in the upper atmosphere that are consistent with observations, yielding significant periodic changes in the temperature structure, the species density distributions, and the large‐scale global wind system. For instance, mid afternoon temperatures near ∼200 km are predicted to vary from ∼210 to 350 K (equinox) and ∼190 to 390 k (aphelion to perihelion) over the solar cycle. These simulations will serve as a benchmark against which to compare episodic variations (e.g., due to solar flares and dust storms) in future M‐GITM studies. Additionally, M‐GITM will be used to support MAVEN mission activities (2014–2016).

Published: December 2014

AbstractCyclic peptides are important natural products and hold great promise for the identification of new bioactive molecules. The split‐intein‐mediated SICLOPPS technology provides a generic access to fully genetically encoded head‐to‐tail cyclized peptides and large libraries thereof (SICLOPPS=split‐intein circular ligation of peptides and proteins). However, owing to the spontaneous protein splicing reaction, product formation occurs inside cells, making peptide isolation inconvenient and precluding traditional in vitro assays for inhibitor discovery. The design of a genetically encoded, light‐dependent intein using the photocaged tyrosine derivative ortho‐nitrobenzyltyrosine incorporated at an internal, non‐catalytic position is now reported. Stable intein precursors were purified from the E. coli expression host and subsequently subjected to light activation in vitro for both the regular protein splicing format and cyclic peptide production, including the natural product segetalin H as an example. The activity of the intein could also be triggered in living cells.
Fabrication of thermoresponsive, core‐crosslinked micelles based on poly[N‐isopropyl acrylamide‐co‐3‐(trimethoxysilyl)propylmethacrylate]‐b‐poly{N‐[3‐(dimethylamino)propyl]methacrylamide} for the codelivery of doxorubicin and nucleic acid

ABSTRACTThermoresponsive amphiphilic copolymer, poly[N‐isopropyl acrylamide‐co‐3‐(trimethoxysilyl)propylmethacrylate]‐b‐poly{N‐[3‐(dimethylamino)propyl]methacrylamide} with a branched structure was designed and synthesized by consecutive reversible addition–fragmentation chain‐transfer polymerization. The further hydrolysis of trimethoxysilyl functions in 3‐(trimethoxysilyl) propyl methacrylate units led to the fabrication of core‐crosslinked (CCL) micelles with silica crosslinks at temperatures above the lower critical solution temperature of the poly(N‐isopropyl acrylamide) block. The thermally induced structural and morphological changes of the CCL micelles in aqueous solution were investigated by transmission electron microscopy and 1H‐NMR analyses. The resulting CCL micelles were further explored as nanocarriers for the codelivery of an anticancer drug and nucleic acid for enhanced therapeutic efficacy. The CCL micelles effectively condensed the nucleic acid and mediated higher gene transfer in the presence of serum than in serum‐free transduction. A cytotoxicity study revealed that whereas the pure CCL micelles exhibited unapparent cytotoxicity, the codelivery of p53 and doxorubicin with the CCL micelle formulation resulted in better treatment efficiency than sole chemotherapy. © 2014 Wiley Periodicals, Inc.

Published: December 2014

ABSTRACTHydrophobic and nanoporous chitosan–silica composite aerogels with low density, high porosity, and superior oil absorbency were successfully prepared by a typical sol–gel method and a two‐step hydrophobic treatment. The morphologies, porosity characteristics, mechanical properties, thermal stability, hydrophobicity, and oil absorbencies of the composite aerogels were systematically investigated. The nitrogen physisorption analysis showed that composite aerogels had large specific surface areas and uniform nanoporous structures. In addition, the composite aerogels could support 7000 times its own weight; this indicated the role of the supporting skeleton played by chitosan. The hydrophobicity and lipophilicity was demonstrated with a water contact angle of 137° and an oil contact angle of 0°. Importantly, the composite aerogel with 20 wt % chitosan had a relatively high oil absorbency of 30 g/g and could be reused up to 10 times. Therefore, the chitosan–silica composite aerogels in this study had a broad prospect to be used as efficient and recyclable oil absorbents. © 2014 Wiley Periodicals, Inc. J. Appl. Polym.

Published: December 2014

AbstractAmyloidogenic proteins share a propensity to convert to the β‐structure‐rich amyloid state that is associated with the progression of several protein‐misfolding disorders. Here we show that a single engineered β‐hairpin‐binding protein, the β‐wrapin AS10, binds monomers of three different amyloidogenic proteins, that is, amyloid‐β peptide, α‐synuclein, and islet amyloid polypeptide, with sub‐micromolar affinity. AS10 binding inhibits the aggregation and toxicity of all three proteins. The results demonstrate common conformational preferences and related binding sites in a subset of the amyloidogenic proteins. These commonalities enable the generation of multispecific monomer‐binding agents.
