APRENDER A APRENDER - NEOLIBERAL? - (2013)

O texto mostra que “aprender a aprender”, como toda temática naturalmente ambígua, pode ser usada para inúmeros fins e oportunismos, mas igualmente para propostas bem fundamentadas. Num primeiro momento sinaliza as tiradas neoliberais e questiona a noção de “aprender a aprender”, destaca que a escola é lugar da aprendizagem do professor e do aluno, da garantia do direito de todos de aprender bem e reconhecer que é fundamental aprender a vida toda do que preferir arruinar o termo porque seria neoliberal. Não ser neoliberal é importante, mas não a preço do despreparo. Na continuidade, as dinâmicas válidas do aprender a aprender, sinalizam o duplo horizonte entre o direito constitucional de aprender bem e, a percepção de que aprender bem implica captar a necessidade de continuar aprendendo a vida toda. Entende que sejam sinalizações neoliberais flagrantes nessas esquerdas da direita: alfabetizar em três anos, ciclos e promoção automática, Ideb, planos conservadores de educação, escola “integral”, aposta no sistema, novas tecnologias, assistências e assistencialismos e nivelamentos por baixo. No último capitulo discute sobre os grafiteiros e os pichadores, afirmando que há muitos “revolucionários” de plantão, contudo o importante é ter abertura solícita e respeitosa a pontos de vista contrários para aprender a aprender. Assim, nada combate melhor o neoliberalismo que a aprendizagem bem feita na escola e por toda a vida, uma educação capaz de aprender a aprender pode contribuir à medida que instiga um tipo de cidadania sempre aberta, crítica e autocrítica, e capaz de conviver com visões divergentes.
Human Exposure to Electromagnetic Fields from Parallel Wireless Power Transfer Systems (2017)

The scenario of multiple wireless power transfer (WPT) systems working closely, synchronously or asynchronously with phase difference often occurs in power supply for household appliances and electric vehicles in parking lots. Magnetic field leakage from the WPT systems is also varied due to unpredictable asynchronous working conditions. In this study, the magnetic field leakage from parallel WPT systems working with phase difference is predicted, and the induced electric field and specific absorption rate (SAR) in a human body standing in the vicinity are also evaluated. Computational results are compared with the restrictions prescribed in the regulations established to limit human exposure to time-varying electromagnetic fields (EMFs). The results show that the middle region between the two WPT coils is safer for the two WPT systems working in-phase, and the peripheral regions are safer around the WPT systems working anti-phase. Thin metallic plates larger than the WPT coils can shield the magnetic field leakage well, while smaller ones may worsen the situation. The orientation of the human body will influence the maximum magnitude of induced electric field and its distribution within the human body. The induced electric field centralizes in the trunk, groin, and genitals with only one exception: when the human body is standing right at the middle of the two WPT coils working in-phase, the induced electric field focuses on lower limbs. The SAR value in the lungs always seems to be greater than in other organs, while the value in the liver is minimal. Human exposure to EMFs meets the guidelines of the International Committee on Non-Ionizing Radiation Protection (ICNIRP), specifically reference levels with respect to magnetic field and basic restrictions on induced electric fields and SAR, as the charging power is lower than 3.1 kW and 55.5 kW, respectively. These results are positive with respect to the safe applications of parallel WPT systems working simultaneously.
Isolation and nucleotide sequence analysis of the ferredoxin I gene from the cyanobacterium Anacystis nidulans R2 (1986)

Two mixed oligonucleotide probes derived from conserved regions of the Synechocystis sp. strain PCC 6714 ferredoxin amino acid sequence were utilized to isolate an Anacystis nidulans R2 clone containing the ferredoxin I gene. Nucleotide sequence analysis revealed a 297-base-pair (bp) open reading frame with a deduced amino acid sequence having high homology to other cyanobacterial ferredoxins. Assuming proteolytic cleavage of the initial methionine residue, the molecular weight of the mature A. nidulans R2 ferredoxin was 10,370. The initial methionine residue was preceded by a probable ribosome-binding site sequence, AGGA. Northern hybridization analysis with the cloned ferredoxin gene indicated an RNA transcript of approximately 450 bp. S1 nuclease mapping localized the transcription start site to a position 64 bases upstream from the initial methionine residue. The nucleotide sequence 14 to 8 bp preceding the transcription start site resembled a typical Escherichia coli promoter, but the sequence in the -35 region did not. Southern hybridization detected only a single copy of the ferredoxin sequence in the A. nidulans R2 genome.
“Turn-On” Protein Fluorescence: In Situ Formation of Cyanine Dyes (2014)

Protein reengineering of cellular retinoic acid binding protein II (CRABPII) has yielded a genetically addressable system, capable of binding a profluorophoric chromophore that results in fluorescent protein/chromophore complexes. These complexes exhibit far-red emission, with high quantum efficiencies and brightness and also exhibit excellent pH stability spanning the range of 2-11. In the course of this study, it became evident that single mutations of L121E and R59W were most effective in improving the fluorescent characteristics of CRABPII mutants as well as the kinetics of complex formation. The readily crystallizable nature of these proteins was invaluable to provide clues for the observed spectroscopic behavior that results from single mutation of key residues.
Reactivity of free thiol groups in type-I inositol trisphosphate receptors (2005)

The IP3R (inositol 1,4,5-trisphosphate receptor) Ca2+-release channel is known to be sensitive to thiol redox state. The present study was undertaken to characterize the number and location of reactive thiol groups in the type-I IP3R. Using the fluorescent thiol-reactive compound monobromobimane we found that approx. 70% of the 60 cysteine residues in the type-I IP3R are maintained in the reduced state. The accessibility of these residues was assessed by covalently tagging the IP3R in membranes with a 5 kDa or 20 kDa MPEG [methoxypoly(ethylene glycol) maleimide]. MPEG reaction caused a shift in the mobility of IP3R on SDS/PAGE that was blocked by pretreatment of the membranes with dithiothreitol, N-ethylmaleimide, mersalyl or thimerosal, indicating that MPEG reactivity was specific to thiol groups on the IP3R. Trypsin cleavage of the type-I IP3R generates five defined domains. In cerebellum membranes, MPEG reacted over a 5 min interval with tryptic fragment I and fragment III, but not fragments II, IV or V. Fragment I appears as a doublet in cerebellum membranes, corresponding to the presence and absence of the SI splice site in this region (SI is a spliced domain corresponding to amino acids 318-332). Only the fragment I band corresponding to the SI(+) splice form shifted after reaction with MPEG. Expression of SI(+) and SI(-) spliced forms in COS cell microsomes confirmed this result. The MPEG-induced shift was not prevented when the cysteine residue present in the SI splice domain (C326A) or the remaining seven cysteine residues in fragment I were individually mutated. Of the combination mutations screened, only the mutation of C206/214/326A blocked MPEG reactivity in fragment I. We conclude that a set of highly reactive cysteine residues in fragment I are differentially accessible in the SI(+) and SI(-) splice variants of the type-I IP3R.
Electric field induced anisotropy in electrostrictive Pb(Mg<sub>1/3</sub>Nb<sub>2/3</sub>)O<sub>3</sub>-PbTiO<sub>3</sub>crystals (1998)

Abstract The electrostrictive behavior in single crystals of Pb(Mg1/3Nb2/3)O3 (PMN) and 0.93Pb(Mg1/3Nb2/3)O3 - 0.07PbTiO3(PMN-7%PT) was investigated as a function of crystallographic direction. The pseudocubic nature of these materials became highly anisotropic at relatively high electric fields. The observed anisotropy was believed to be associated with an electric field induced rhombohedral symmetry. Strain values were found to be larger for (001) oriented crystals though larger polarization values were measured in (111) oriented crystals, a consequence of larger electrostrictive coefficients (Qij ). The electrostrictive coefficient Qij of the induced phase was found to be independent of composition. Though the crystals exhibited a high degree of anisotropy, no apparent improvement in induced polarization or strain was found when compared with polycrystalline counterparts.
A Survey of Urban Reconstruction (2012)

This paper provides a comprehensive overview of urban reconstruction. While there exists a considerable body of literature, this topic is still under very active research. The work reviewed in this survey stems from the following three research communities: computer graphics, computer vision, and photogrammetry and remote sensing. Our goal is to provide a survey that will help researchers to better position their own work in the context of existing solutions, and to help newcomers and practitioners in computer graphics to quickly gain an overview of this vast field. Further, we would like to bring the mentioned research communities to even more interdisciplinary work, since the reconstruction problem itself is by far not solved.
Ethical Issues of Psychological and Psychotherapeutic Means of Behavior Control (1973)

n sharp contrast to psychosurgery and, to a lesser degree, to scientific psychopharmacology, psychological and psychotherapeutic methods of behavior control are an ancient phenomenon. They have been described, studied, understood (and misunderstood) since man has thought about his world. We are not, in my opinion, here faced with explosions of new knowledge or new techniques of applying that knowledge. Nevertheless, our understanding of behavior and our ability to influence it by psychological means are slowly growing, and the social and ethical implications of this knowledge are so immense as to dwarf even the importance of our understanding of the physical world. A second difference between psychological means of control and surgical or chemical means relates to the distribution of the knowledge and skill required to exercise the control. Few of us are equipped to intrude physically into nervous systems of our fellow man. Many more
Transition‐State Stabilization by a Secondary Substrate–Ligand Interaction: A New Design Principle for Highly Efficient Transition‐Metal Catalysis (2010)

A library of monodentate phosphane ligands, each bearing a guanidine receptor unit for carboxylates, was designed. Screening of the library gave some excellent catalysts for regioselective hydroformylation of beta,gamma-unsaturated carboxylic acids. A terminal alkene, but-3-enoic acid, was hydroformylated with a linear/branched (l/b) regioselectivity up to 41. An internal alkene, pent-3-enoic acid was hydroformylated with regioselectivity up to 18:1. Further substrate selectivity (e.g., acid vs. methyl ester) and reaction site selectivity (monofunctionalization of 2-vinylhept-2-enoic acid) were also achieved. Exploration of the structure-activity relationship and a practical and theoretical mechanistic study gave us an insight into the nature of the supramolecular guanidinium-carboxylate interaction within the catalytic system. This allowed us to identify a selective transition-state stabilization by a secondary substrate-ligand interaction as the basis for catalyst activity and selectivity.
A Machine Learning Approach for Predicting Execution Time of Spark Jobs (2018)

Spark has gained growing attention in the past couple of years as an in-memory cloud computing platform. It supports execution of various types of workloads such as SQL queries and machine learning applications. Currently, many enterprises use Spark to exploit its fast in-memory processing of large scale data. Additionally, speeding up the execution in Spark is an important problem for many real-time applications. This can be achieved by improving the scheduling approaches employed by Spark, optimizing the execution plans generated by Spark for various applications, and selecting the best cluster configuration to run an input workload. A first step for all these optimization approaches is to predict the execution time of an input Spark application. In this paper, we present a new platform that predicts with high accuracy the execution time of SQL queries and machine learning applications executed by Spark. We evaluate our proposed platform by measuring the accuracy of predicting execution time of various types of Spark jobs including TPC-H queries and machine learning classification/clustering applications. The evaluation experiments show that we are able to predict the execution time of Spark jobs using our proposed platform with accuracy greater than 90% for SQL queries and greater than 75% for machine learning jobs.

The combination of in situ hybridization and immunohistochemical analysis: an evaluation of Her2/neu expression in paraffin-embedded breast carcinomas and adjacent normal-appearing breast epithelium. (1997)

The combination of in situ hybridization and immunohistochemical techniques can successfully identify viral DNA/RNA in specific subsets of cellular populations. We recently modified this method to evaluate amplification of the oncogene Her2/neu and overexpression of its protein c-erbB-2 in a series of 15 breast carcinomas. This combination allows the simultaneous evaluation of the oncogene and its corresponding protein expression in single cells and specific cellular populations in histologic tissue sections. Double staining demonstrated heterogeneity within breast carcinomas. In addition, both nuclear and cytoplasmic signals were often detected in morphologically normal-appearing adjacent breast epithelium. The ability to view both the oncogene and its corresponding protein in single cells offers a unique look at the biology of c-erbB-2.
Amplification and expression of the HMGIC gene in a benign endometrial polyp (1998)

Polymerization of Naturally Renewable Methylene Butyrolactones by Half-Sandwich Indenyl Rare Earth Metal Dialkyls with Exceptional Activity (2010)

Four discrete half-sandwich dialkyl rare earth metal (REM) complexes incorporating a disilylated indenyl ligand, (1,3-(SiMe3)2C9H5)M(CH2SiMe3)2(THF) (M = Sc, Y, Dy, Lu), have been investigated for the coordination−addition polymerization of naturally renewable methylene butyrolactones, α-methylene-γ-butyrolactone (MBL) and γ-methyl-α-methylene-γ-butyrolactone (MMBL). Initial screening for the polymerization of methyl methacrylate highlighted several differences in catalytic behavior between these half-sandwich REM catalysts and well-studied sandwich REM catalysts in terms of reactivity trend, polymer tacticity, and solvent dependence. Most significantly, all four catalysts herein exhibit exceptional activity for polymerization of MMBL in DMF, achieving quantitative monomer conversion in <1 min with a 0.20 mol % catalyst loading and giving a high turnover frequency of >30 000 h−1. Slower polymerizations occur in CH2Cl2, allowing for establishment of the activity trend within this REM series, which follows: Dy (largest ion) ≥ Y > Lu > Sc (smallest ion). The most active and effective Dy catalyst has been examined in detail, demonstrating its ability to control the polymerization for producing PMMBL with high Tg (221 °C) and with molecular weight ranging from a medium Mn of 1.89 × 104 Da to a high Mn of 1.63 × 105 Da, programmed by the [MMBL]/[Dy] ratio. Kinetic experiments have revealed a first-order dependence on [monomer] and a second-order dependence on [REM]. These kinetic results, coupled to catalyst efficiencies, NMR studies, as well as with chain-end group analysis by MALDI-TOF mass spectrometry, have yielded a chain initiation mechanism that involves both alkyl groups on each metal center and a bimolecular chain propagation that involves two metal centers in the rate-limiting C−C bond forming step. The Dy catalyst response to enolizable organo acids, externally added as chain-transfer agents, has also been examined.

d-(−)-Lactic acid production from cellobiose and cellulose by Lactobacillus lactis mutant RM2-24 (2010)

Lactobacillus lactis mutant RM2-24 utilizes cellobiose efficiently, converting it into D-(−)-lactic acid. Cellobiose-degrading enzyme activities were determined for whole cells, cell extracts and disrupted cells. Aryl-β-glucosidase activity was detected in whole cells and disrupted cells, suggesting that these activities are confined to the cells. The mutant produced 80 g l−1 of lactic acid from 100 g l−1 of cellobiose with 1.66 g l−1 h−1 productivity. Production of D-lactic acid from different cellulose samples was also studied. The cellulose samples at high concentration (10%) were hydrolyzed by cellulase enzyme preparation (10 FPU g−1 cellulose) derived from Penicillium janthinellum mutant EU1 generated in our own laboratory. We obtained a maximum 72% hydrolysis, yielding glucose and cellobiose as the main end products. Lactic acid was produced from these cellulose samples by simultaneous saccharification and fermentation (SSF) in a media containing a cellulase enzyme preparation derived from Penicillium janthinellum mutant EU1 and cellobiose utilizing Lactobacillus lactis mutant RM2-24. A maximum lactic acid concentration of 73 g l−1 was produced from a concentration of 100 g l−1 of bagasse-derived cellulose, the highest productivity and yield being 1.52 g l−1 h−1 and 0.73 g g−1, respectively. Considering that bagasse is a waste material available in abundance, we propose to use this biomass to produce cellulose and then sugars, which can be fermented to valuable products such as ethanol and lactic acid.
Crystallographic characterization of epitaxial Pb(Zr,Ti)O3 films with different Zr/Ti ratio grown by radio-frequency-magnetron sputtering (2003)

Crystallographic structure of as-grown epitaxial Pb(Zr,Ti)O3 (PZT) films was investigated with regard to the Zr/Ti ratio and crystalline orientation. PZT films with (001) and (111) orientation were epitaxially grown on (100) and (111)SrTiO3 substrates respectively using radio-frequency (rf) sputtering. Four circle x-ray diffraction measurements revealed that the crystallographic dependence on Zr/Ti composition in PZT films was much different from bulk PZT. In particular, (001)-oriented PZT films showed tetragonal structure even in the Zr/Ti composition of 70/30 where the bulk PZT ceramics are rhombohedral phase. In addition, although (001)-oriented PZT films with Zr/Ti ratio of 53/47 and 70/30 showed tetragonal structure, (111)-oriented PZT films with the same Zr/Ti ratio were identified as the rhombohedral structure. The cell volume of the PZT films with both orientations increased, suggesting the excess Pb atoms in the films due to the impinging energetic sputtered particles induces the anomalous crystalline structure of the PZT films. Dielectric properties of the PZT films exhibited stable value independent of Zr/Ti ratio and characteristic increase of dielectric constant near Zr/Ti=53/47 could not be observed. These results suggest that the internal stress due to the sputter deposition plays an important roll in the unique characteristics of crystallographic and electrical properties of the epitaxial PZT films.
