Este estudo analisa teses e dissertações produzidas nos últimos 20 anos com o objetivo de compreender as relações da música no contexto da formação acadêmico-profissional dos cursos de Licenciatura em Pedagogia. Foram mapeadas 33 pesquisas defendidas em programas brasileiros de pós-graduação, tendo sido agrupadas em dois blocos: formação continuada com 18 trabalhos e formação acadêmico-profissional com 15. Em ambos foram descritos e analisados temas, objetivos, referenciais teóricos, procedimentos metodológicos e resultados. O segundo grupo de pesquisas recebeu um tratamento de dados mais detalhado e os resultados demonstram que: as temáticas mais estudadas referem-se à estrutura dos cursos, identidades das estudantes, processos da docência e o lugar da música na Pedagogia; o estudo de caso foi a metodologia adotada por 40% dos pesquisadores; os emissores do discurso sobre pedagogia e educação musical são autores nacionais e estrangeiros; a legislação educacional é mencionada na maioria dos trabalhos; programas de Pós-Graduação em Educação produzem mais pesquisas na temática em questão do que os de música; a carga horária nos cursos não é suficiente para a aprendizagem de um conhecimento específico em música; as parcerias entre professoras de referências e professoras especialistas têm sido uma alternativa de atuação para as egressas; entre outros. Para dar continuidade às investigações, aponta-se, por um lado, a necessidade de estudos em todas as regiões e in loco e, por outro, a inclusão das músicas do cotidiano das crianças na formação das pedagogas.
Evidence of the Existence of Three Types of Species at the Quartz−Aqueous Solution Interface at pH 0−10: XPS Surface Group Quantification and Surface Complexation Modeling (2002)

The surface composition of a quartz surface reacted with various aqueous solutions of pH 0−10 was qualitatively and quantitatively evaluated using X-ray photoelectron spectroscopy (XPS). The positions and intensities of the recorded Si 2p and O 1s lines change depending on solution conditions. The O 1s line, where the position varies more significantly, was analyzed in detail showing three components corresponding to three surface species: >SiOH2+, >SiOH0, and >SiO- (where > represents the bulk quartz). The changes in the Si 2p spectra support these findings. The atomic ratio between the surface oxygen and silicon atoms was found to be 1.8. These data allow proposing a two-step deprotonation model of the quartz surface where two surface oxygen atoms are bonded to one silicon surface atom and where the most deprotonated surface sites show the SiO- configuration. Physisorbed water in the amount of around 10% of the monolayer was also found on all samples under spectroscopic investigation. The density of the >SiO- group increases significantly with an increase of pH, whereas the surface concentration of the >SiOH2+ group is the highest at pH 0. The maximum of the neutral >SiOH0 group is observed at pH 6. These results indicate immediately the validity of a 2-pK model of protonation of quartz/electrolyte interface versus a 1-pK model. The 2-pK surface capacitance model of the electric double layer having pK1 = − 1.0 and pK2 = 4.0 was derived from the XPS data. The new surface stability constants allow a quantitative description of quartz surface charge and dissolution kinetics in neutral to alkaline solutions and explicitly account for an increase of quartz dissolution rate at pH < 2 due to significant increase of the concentration of the >SiOH2+ surface species. These results provide, for the first time, direct atomic level spectroscopic evidence of the validity of the chemical surface speciation approach, notably the existence of the charged >SiOH2+ and >SiO- species at the quartz surface and their relative densities in acidic and alkaline solutions.
Optimal outpatient appointment scheduling (2007)

In this paper optimal outpatient appointment scheduling is studied. A local search procedure is derived that converges to the optimal schedule with a weighted average of expected waiting times of patients, idle time of the doctor and tardiness (lateness) as objective. No-shows are allowed to happen. For certain combinations of parameters the well-known Bailey-Welch rule is found to be the optimal appointment schedule.
Noncontact Thermal and Vibrotactile Display Using Focused Airborne Ultrasound (2020)

In a typical mid-air haptics system, focused airborne ultrasound provides vibrotactile sensations to localized areas on a bare skin. Herein, a method for displaying thermal sensations to hands where mesh fabric gloves are worn is proposed. The gloves employed in this study are commercially available mesh fabric gloves with sound absorption characteristics, such as cotton work gloves without any additional devices such as Peltier elements. The method proposed in this study can also provide vibrotactile sensations by changing the ultrasonic irradiation pattern. In this paper, we report basic experimental investigations on the proposed method. By performing thermal measurements, we evaluate the local heat generation on the surfaces of both the glove and the skin by focused airborne ultrasound irradiation. In addition, we performed perceptual experiments, thereby confirming that the proposed method produced both thermal and vibrotactile sensations. Furthermore, these sensations were selectively provided to a certain extent by changing the ultrasonic irradiation pattern. These results validate the effectiveness of our method and its feasibility in mid-air haptics applications.
Public Policy Issues in the Marketing of Seals of Approval for Food (1993)

Seals of approval have been part of the competitive environment for decades and, properly used, aid consumers by substituting unbiased professional expertise for consumers' lack of knowledge regarding product claims. This paper analyzes use of seals of approval as fund‐raising and competitive devices to determine if seals of approval for food offer the same public good as product endorsements. The authors conclude that seals of approval for food, as exemplified by the American Heart Association's HeartGuide Seal, may not be in the best interests of consumers.
EHANCEMENT OF WIRELESS POWER TRANSMISSION INTO BIOLOGICAL TISSUES USING A HIGH SURFACE IMPEDANCE GROUND PLANE (2013)

The system which enhances wireless power transmission efficiency for bio-medical applications has been proposed in this report. The system that operates at giga-hertz ranges is based on an inductive coupling between a transmitter coil and a receiver coil. A magnetic current source was modeled to a magnetic dipole with magnetic dipole moment m. To increase wireless power transmission efficiency, a high surface impedance ground plane was used and reflection from the ground plane is responsible for constructive interference. For this system, a theoretical study has been performed in this report by solving Sommerfeld integrals. Compared with the result of a system without a ground plane, the system with a high surface impedance ground plane showed enhancement of received power at a given transmitted power.
A public-key infrastructure for key distribution in TinyOS based on elliptic curve cryptography (2005)

We present the first known implementation of elliptic curve cryptography over F/sub 2p/ for sensor networks based on the 8-bit, 7.3828-MHz MICA2 mote. Through instrumentation of UC Berkeley's TinySec module, we argue that, although secret-key cryptography has been tractable in this domain for some time, there has remained a need for an efficient, secure mechanism for distribution of secret keys among nodes. Although public-key infrastructure has been thought impractical, we argue, through analysis of our own implementation for TinyOS of multiplication of points on elliptic curves, that public-key infrastructure is, in fact, viable for TinySec keys' distribution, even on the MICA2. We demonstrate that public keys can be generated within 34 seconds, and that shared secrets can be distributed among nodes in a sensor network within the same, using just over 1 kilobyte of SRAM and 34 kilobytes of ROM.
Macromodeling and Optimization of Digital MOS VLSI Circuits (1986)

Power consumption and signal delay are crucial to the design of high-performance VLSI circuits. This paper presents CAD tools for modeling and optimizing digital MOS designs. The tools determine the transistor sizes that minimize circuit power consumption subject to constraints on signal path delays. Computational efficiency is obtained through macromodeling techniques and a specialized optimization algorithm. The macromodels are based on device equations, and encapsulate logic gate behavior in a set of simple yet accurate formulas. The optimization algorithm exploits properties of the digital MOS domain to convert the primal optimization problem into a dual form which is much easier to solve. The result is a pair of CAD tools that can optimize a circuit in roughly the amount of time needed to perform a transistor-level simulation of the circuit.
NNZ-2566, a Glypromate Analog, Attenuates Brain Ischemia-Induced Non-Convulsive Seizures in Rats (2009)

Ischemic and traumatic brain injuries often induce non-convulsive seizures (NCSs), which likely contribute to the worsening of neurological outcomes. Here, we evaluated the effect of glycyl-L-methylprolyl-L-glutamic acid (NNZ-2566) to lessen the severity of NCSs caused by permanent middle cerebral artery occlusion (pMCAo). Continuous electroencephalographic recordings were performed in rats during pMCAo. Glycyl-L-methylprolyl-L-glutamic acid (3, 10, or 100 mg/kg bolus followed by an infusion of a fixed dose of 3 mg/kg per hour for 12 h) was delivered at 20 mins after pMCAo (before the first NCS event) or delayed until immediately after the first NCS event occurred. Control rats received pMCAo and saline treatment. The results revealed that 91% of the saline-treated animals had NCSs (23 episodes per rat and 1238 secs per rat) with an onset latency of 35 mins after injury. When NNZ-2566 was administered before the NCS events, it dose-dependently reduced the NCS incidence to 36%-80%, decreased NCS frequency to 5-16 episodes per rat, and shortened the total duration of NCS to 251-706 secs per rat. The two high doses significantly reduced the infarct volume by 28%-30%. Delayed treatment also attenuated NCS duration but had no effect on the infarct volume. Results indicate that NNZ-2566 possesses a unique therapeutic potential as a safe prophylactic agent that synergistically provides neuroprotection and reduces injury-induced seizures.
Development and Application of an Integrated Dew Point and Glass Temperature Sensor (2001)

<div class="htmlview paragraph">With the optimization of HVAC system controls for comfort, air quality and energy efficiency the potential for fogging the glass has increased. To maintain occupant safety, a method to predict when such fogging conditions exist is necessary to be able to execute proactive control corrections to prevent fogging. Windshield fog conditions are predicated on windshield surface temperature, cabin relative humidity and the reference temperature of the humidity sensor. This has driven a joint development project between Delphi Automotive Systems divisions to develop an Integrated Dew Point and Glass Temperature (IDGT) sensor. This sensor is a combination of three elements: a glass temperature sensor, a relative humidity sensor, and a humidity reference temperature sensor. Using this sensor package, the cabin dew point is calculated from the relative humidity and humidity reference temperature for comparison with the windshield glass temperature. When the windshield glass temperature drops to or is below the cabin dew point temperature, fog will form on the windshield. Utilizing this information, a proactive automatic climate control system implements corrections before the occurrence of fogging.</div> <div class="htmlview paragraph">This paper discusses the following issues concerning this new technology:</div> <div class="htmlview paragraph"> <ul class="list disc"> <li class="list-item"><div class="htmlview paragraph">Sensor design and development.</div></li> <li class="list-item"><div class="htmlview paragraph">A comparison between the existing technologies and the new sensor design.</div></li> <li class="list-item"><div class="htmlview paragraph">Vehicle / system integration of the sensor.</div></li> </ul> </div>

Coal-clay waste slurries were dewatered in laboratory- and small-scale continuous tests by the Bureau of Mines using polyethylene oxide (PEO) as a flocculant.
Development in Lithium/Sulfur Secondary Batteries (2011)

This paper reviews different modification methods to cathode, anode and electrolyte materials in view of their electrochemical properties for application in lithium/sulfur batteries. In the sulfur electrode, carbonaceous materials, conductive polymer materials, and metal oxide adsorbing materials are employed to enhance conductivity and reduce polysulfide dissolution. The effects of anodes and novel electrolytes, such as gel polymer, solid polymer and solid ceramic electrolytes, are reviewed.
Rac1 mediates laminar shear stress-induced vascular endothelial cell migration (2013)

The migration of endothelial cells (ECs) plays an important role in vascular remodeling and regeneration. ECs are constantly subjected to shear stress resulting from blood flow and are able to convert mechanical stimuli into intracellular signals that affect cellular behaviors and functions. The aim of this study is to elucidate the effects of Rac1, which is the member of small G protein family, on EC migration under different laminar shear stress (5.56, 10.02, and 15.27 dyn/cm(2)). The cell migration distance under laminar shear stress increased significantly than that under the static culture condition. Especially, under relative high shear stress (15.27 dyn/cm(2)) there was a higher difference at 8 h (P<0.01) and 2 h (P<0.05) compared with static controls. RT-PCR results further showed increasing mRNA expression of Rac1 in ECs exposed to laminar shear stress than that exposed to static culture. Using plasmids encoding the wild-type (WT), an activated mutant (Q61L), and a dominant-negative mutant (T17N), plasmids encoding Rac1 were transfected into EA.hy 926 cells. The average net migration distance of Rac1Q61L group increased significantly, while Rac1T17N group decreased significantly in comparison with the static controls. These results indicated that Rac1 mediated shear stress-induced EC migration. Our findings conduce to elucidate the molecular mechanisms of EC migration induced by shear stress, which is expected to understand the pathophysiological basis of wound healing in health and diseases.

The I-BAR protein Ivy1 is an effector of the Rab7 GTPase Ypt7 involved in vacuole membrane homeostasis (2015)

Membrane fusion at the vacuole depends on a conserved machinery that includes SNAREs, the Rab7 homolog Ypt7 and its effector HOPS. Here, we demonstrate that Ypt7 has an unexpected additional function by controlling membrane homeostasis and nutrient-dependent signaling on the vacuole surface. We show that Ivy1, the yeast homolog of mammalian missing-in-metastasis (MIM), is a vacuolar effector of Ypt7-GTP and interacts with the EGO/ragulator complex, an activator of the target of rapamycin kinase complex 1 (TORC1) on vacuoles. Loss of Ivy1 does not affect EGO vacuolar localization and function. In combination with the deletion of individual subunits of the V-ATPase, however, we observed reduced TORC1 activity and massive enlargement of the vacuole surface. Consistent with this, Ivy1 localizes to invaginations at the vacuole surface and on liposomes in a phosphoinositide- and Ypt7-GTP-controlled manner, which suggests a role in microautophagy. Our data, thus, reveal that Ivy1 is a novel regulator of vacuole membrane homeostasis with connections to TORC1 signaling.
Fake news game confers psychological resistance against online misinformation (2019)

Abstract The spread of online misinformation poses serious challenges to societies worldwide. In a novel attempt to address this issue, we designed a psychological intervention in the form of an online browser game. In the game, players take on the role of a fake news producer and learn to master six documented techniques commonly used in the production of misinformation: polarisation, invoking emotions, spreading conspiracy theories, trolling people online, deflecting blame, and impersonating fake accounts. The game draws on an inoculation metaphor, where preemptively exposing, warning, and familiarising people with the strategies used in the production of fake news helps confer cognitive immunity when exposed to real misinformation. We conducted a large-scale evaluation of the game with N = 15,000 participants in a pre-post gameplay design. We provide initial evidence that people’s ability to spot and resist misinformation improves after gameplay, irrespective of education, age, political ideology, and cognitive style.
An agent version of a cluster server (2003)

Agent-oriented software engineering is promising substantial improvements especially for the design of distributed systems. But currently, there is a substantial gap between the massive number of publications advocating advantages of agents and the relatively small number of successful large applications. We present an agent-based cluster server application together with the analysis of advantages and disadvantages of the agent-based version compared to the non agent-based version of functionally similar cluster server application. Obtained experience is analyzed from the viewpoints of designers, developers and users. Observations confirm several previously published advantages of the agent-based approach and implementation: yet reveal some less familiar disadvantages as well. Overall, we argue that agents provide reasonable benefits already at this stage, while we lack further agent-based research.
THE ROLE OF INTERLEUKIN 1 IN ACUTE PHASE SERUM AMYLOID A (SAA) AND SERUM AMYLOID P (SAP) BIOSYNTHESIS* (1982)

The acute phase SAA and SAP profiles have been compared for localized and endotoxin induced inflammation in LPS responder and nonresponder strains of mice. The SAP profile can reflect a delay with respect to the start of the increase. Its maximum is on the order of ten times the nonacute phase concentration and elevated concentrations are sustained 24 to 48 hours after SAA concentration is rapidly decreasing to normal. The role of Interleukin 1, known to have an essential role in SAA production, was investigated for SAP production. Purified mouse IL 1 and rabbit IL 1 produced a minimal elevation of SAP concentration above normal values, especially when compared with their effects on SAA concentration. BCG infection was shown to synergistically augment SAA induction by LPS and was shown to enhance IL 1 production by macrophages in response to LPS. Unlike SAA synthesis, BCG-preinfection fails to synergistically augment the LPS-induced SAP response. BCG infection alone produced highly elevated and sustained increases in SAP concentration, whereas, the effect on SAA concentration was minimal. Macrophages appear to play an important role in SAP acute phase elevation, but the mechanism in different from that of SAA elevation.
Několik úvah o české historiografii po roce 1989 (2022)

Článek se zabývá stavem historického bádání v Československu (České republice) po roce 1989, v komparativní regionální perspektivě. První část textu pojednává fenomén relativního opoždění české diskuse o dopadech komunistického režimu na historiografii. Autor shrnovaného článku zastává názor, že vzhledem k tomuto časovému posunu dospěla česká historiografie k daleko sofistikovanější a metodologicky propracovanější debatě než na počátku 90. let 20. století dosáhli v obdobných diskusích polští, němečtí a slovenští historici. Druhá část článku se věnuje hlavním výzkumným tématům soudobé české historiografie, počínaje husitským hnutím, přes národní obrození k problému odsunu německého obyvatelstva z Československa po roce 1945. Podle autora dokazují nedávné kritické hlasy vůči tradiční interpretaci imanentně demokratického, mírového a jedinečného charakteru meziválečného Československa přesvědčivěji demokratičnost a profesní kvality současné české historické vědy než „patriotická“ obrana národních hodnot.
In Vivo Human Somitogenesis Guides Somite Development from hPSCs (2017)

Somites form during embryonic development and give rise to unique cell and tissue types, such as skeletal muscles and bones and cartilage of the vertebrae. Using somitogenesis-stage human embryos, we performed transcriptomic profiling of human presomitic mesoderm as well as nascent and developed somites. In addition to conserved pathways such as WNT-β-catenin, we also identified BMP and transforming growth factor β (TGF-β) signaling as major regulators unique to human somitogenesis. This information enabled us to develop an efficient protocol to derive somite cells in vitro from human pluripotent stem cells (hPSCs). Importantly, the in-vitro-differentiating cells progressively expressed markers of the distinct developmental stages that are known to occur during in vivo somitogenesis. Furthermore, when subjected to lineage-specific differentiation conditions, the hPSC-derived somite cells were multipotent in generating somite derivatives, including skeletal myocytes, osteocytes, and chondrocytes. This work improves our understanding of human somitogenesis and may enhance our ability to treat diseases affecting somite derivatives.

Size and dose dependent effects of silver nanoparticle exposure on intestinal permeability in an in vitro model of the human gut epithelium (2016)

The results of this study show that small-size AgNP have significant effects on intestinal permeability in an in vitro model of the human gastrointestinal epithelium. Such effects have the potential to compromise the integrity of the intestinal epithelium and this disruption of barrier function could have health consequences for the gastrointestinal tract.
Lung mucus: a clinician's view (1997)

Respiratory mucus represents the products derived from secretion of the submucosal glands and the goblet cells. Accumulation of mucus in the airway tree may be caused by an increased volume of mucus produced, and also by decreased clearance due to defects in the ciliary clearance apparatus. Hypersecretion of mucus contributes to the morbidity of airway diseases by predisposing patients to respiratory infections, and contributing to airflow obstruction and to patients' discomfort. There is a significant association between chronic production of mucus and an increased risk of mortality. Also the degree of airway obstruction is related to the physical properties of the sputum. Observation of chronic bronchitic sputum can reveal important clinical information concerning the type and level of the inflammatory process, the physical properties of the material, the extent of bronchial mucosal damage, and the identification of pathogenic microorganisms that may be present. The management of mucous hypersecretion can be undertaken in two main ways: firstly, improved clearance by physical methods; and, secondly, by pharmacological methods.
