Auger electron spectroscopy study of semiconductor surfaces: Effect of cleaning in inert atmosphere
Authors: Debehets Jolien , Miranda Sérgio M. C. , Homm Pía , Houssa Michel , Seefeldt Marc , Locquet Jean-Pierre , Seo Jin Won
Published: July 2016

In this paper, the authors demonstrate that Auger electron spectroscopy (AES) is an effective characterization tool in the analysis of the cleaning of semiconductor surfaces under different atmospheres. AES has several advantages for this purpose: it is nondestructive, surface specific {the analysis depth is only 4–50 Å [Childs et al., Handbook of Auger Electron Spectroscopy (Physical Electronics, Eden Prairie, MN, 1995)]}, and very sensitive to common contaminants such as carbon and oxygen. Furthermore, the authors have proven that AES allows us to describe the effectiveness of surface cleaning in a quantitative manner by comparing the peak-to-peak height of the oxygen signal for different samples. In this work, the surface cleaning of five semiconductors, namely, Si, Ge, GaAs, In0.5Ga0.5As, and In0.5Al0.5As, was investigated. The same standard HF cleaning procedure was applied in two different atmospheres, air or nitrogen. The latter was used to prevent reoxidation after cleaning. The authors found that for most of these semiconductors, the atmosphere in which the cleaning is performed has a significant influence on the results, reducing the oxygen peak-to-peak height with an extra 11.18% (average of all the semiconductors investigated) when comparing cleaning in N2 to cleaning in air. Complementary characterization of the effectiveness of the cleaning procedure was accomplished by in situ AES, atomic force microscopy, and reflection high-energy electron diffraction for GaAs samples.
Scattering reduction of an acoustically hard cylinder covered with layered pentamode metamaterials
Authors: Boisvert Jeffrey E. , Scandrett Clyde L. , Howarth Thomas R.
Published: July 2016

Transformational acoustics offers the theoretical possibility of cloaking obstacles within fluids, provided metamaterials having continuously varying bulk moduli and densities can be found or constructed. Realistically, materials with the proper, continuously varying anisotropies do not presently exist. However, discretely layered cloaks having constant material parameters within each layer may be a viable alternative in practice. The present work considers a range of cloaks, from those comprised of fluid layers that are isotropic in bulk moduli with anisotropic density (inertial cloaks) to those having anisotropic bulk moduli and isotropic density (pentamode cloaks). In this paper an analytical solution is obtained for the case of plane wave scattering from a submerged rigid cylinder covered with a multilayered cylindrical cloak composed of discrete anisotropic fluid layers. An investigation of the parameter space defining such cloaks is undertaken with the goal of minimizing the far-field scattered pressure, using layer constituent anisotropic properties (density and bulk modulus) constrained to lie within reasonable ranges relative to those of water.
Acoustic performance of boundaries having constant phase gradient
Authors: Wang Xu , Wang Xiaonan , Yu Wuzhou , Jiang Zaixiu , Mao Dongxing
Published: July 2016

In this paper, inhomogeneous boundaries having constant phase gradient are investigated. In principle, such a theoretically proposed boundary is dispersionless. In practice, however, when the boundary is realized by a subwavelength-structured tubes array, the impedance discretization brings about sub-reflections at high frequencies. Moreover, determined by the longest duct in the array, a realized boundary is impractically thick. Therefore, a finite-thickness boundary is further proposed by truncating and periodizing the tubes in the array. In this paper, the theoretical analysis agrees well with the numerical simulations. By appropriately choosing its phase gradient and target frequency, the finite-thickness boundaries have potential applications in noise control.
The Relationship Between Hip Kinematics and Iliotibial Band Syndrome (ITBS) in Long Distance Runners: A Critically Appraised Topic
Authors: Loudon Janice K. , Swift Marcie
Published: July 2016

Clinical Question:

Is there evidence to suggest that runners with a history of ITBS demonstrate altered lower extremity kinematics compared with runners without a history of ITBS?

Clinical Bottom Line:

There is moderate evidence suggesting that hip kinematics differ between runners with a history of ITBS compared with healthy runners. Results are contradictory related to the plane of movement and direction of the kinematic change. In addition, assessing hip kinematics following an exhaustive run may be beneficial to detect change.
Sex-specific responses to climate change in plants alter population sex ratio and performance

Changing sex ratios

Climate-warming temperatures might be expected to affect the sex ratio of species if sex determination is temperature-dependent. Petry
et al.
show that indirect climate effects could also alter sex ratios in species in which sex is genetically determined and damage reproductive fitness (see the Perspective by Etterson and Mazer). Over four decades, sex ratios in populations of a dioecious alpine plant have shifted toward females as a result of the different water needs of the male and female plants. The lack of males has reduced the reproductive success and fitness of the females. Similar subtle differences between sexes in environmental sensitivities could eventually lead to population declines.

Submaximal fitness and mortality risk reduction in coronary heart disease: a retrospective cohort study of community-based exercise rehabilitation
Authors: Taylor Claire , Tsakirides Costas , Moxon James , Moxon James William , Dudfield Michael , Witte Klaus K , Ingle Lee , Carroll Sean
Published: July 2016

Objectives

To examine the association between submaximal cardiorespiratory fitness (sCRF) and all-cause mortality in a cardiac rehabilitation (CR) cohort.

Design

Retrospective cohort study of participants entering CR between 26 May 1993 and 16 October 2006, followed up to 1 November 2013 (median 14 years, range 1.2–19.4 years).

Setting

A community-based CR exercise programme in Leeds, West Yorkshire, UK.

Participants

A cohort of 534 men (76%) and 136 women with a clinical diagnosis of coronary heart disease (CHD), aged 22–82 years, attending CR were evaluated for the association between baseline sCRF and all-cause mortality. 416 participants with an exercise test following CR (median 14 weeks) were examined for changes in sCRF and all-cause mortality.

Main outcome measures

All-cause mortality and change in sCRF expressed in estimated metabolic equivalents (METs).

Results

Baseline sCRF was a strong predictor of all-cause mortality; compared to the lowest sCRF group (<5 METs for women and <6 METs for men), mortality risk was 41% lower in those with moderate sCRF (HR 0.59; 95% CI 0.42 to 0.83) and 60% lower (HR 0.40; 95% CI 0.25 to 0.64) in those with higher sCRF levels (≥7 METs women and ≥8 METs for men). Although improvement in sCRF at 14 weeks was not associated with a significant mortality risk reduction (HR 0.91; 95% CI 0.79 to 1.06) for the whole cohort, in those with the lowest sCRF (and highest all-cause mortality) at baseline, each 1-MET improvement was associated with a 27% age-adjusted reduction in mortality risk (HR 0.73; 95% CI 0.57 to 0.94).

Conclusions

Higher baseline sCRF is associated with a reduced risk of all-cause mortality over 14 years in adults with CHD. Improving fitness through exercise-based CR is associated with significant risk reduction for the least fit.
Efficacy and safety of bevacizumab plus erlotinib versus bevacizumab or erlotinib alone in the treatment of non-small-cell lung cancer: a systematic review and meta-analysis
Authors: Zhang Shu , Mao Xiao-dong , Wang Hai-tao , Cai Feng , Xu Jing
Published: July 2016

Objectives

Bevacizumab and erlotinib inhibit different tumour growth pathways, and both exhibit beneficial effects in the treatment of non-small-cell lung cancer (NSCLC). However, the efficacy of bevacizumab in combination with erlotinib remains controversial. Therefore, we conducted a meta-analysis to compare combination treatment with bevacizumab and erlotinib to bevacizumab or erlotinib monotherapy in the treatment of NSCLC.

Methods

Randomised controlled trials (RCTs) published in PubMed, Web of Science and EMBASE were systematically reviewed. The main outcome measures included overall survival (OS), progression-free survival (PFS), overall response rate (ORR) and adverse events. Results were expressed as HRs or risk ratios (RRs) with 95% CIs.

Results

5 RCTs involving a total of 1736 patients were included in this meta-analysis. The combination of bevacizumab and erlotinib significantly improved PFS (HR=0.63, 95% CI 0.53 to 0.75; p=0.000) and the ORR (RR=1.91, 95% CI 1.19 to 3.06; p=0.007) in the second-line treatment of NSCLC compared with bevacizumab or erlotinib alone. However, no significant difference in OS was observed between the combination and monotherapy groups (HR=0.96, 95% CI 0.83 to 1.11; p=0.573). A subgroup analysis has shown that the greatest PFS benefit was associated with an age of <65 years(HR=0.74, 95% CI 0.57 to 0.96; p=0.026), Asian/Pacific Islander ethnicity (HR=0.23, 95% CI 0.10 to 0.54; p=0.001), Eastern Cooperative Oncology Group performance status (ECOG PS) 1 (HR=0.82, 95% CI 0.68 to 0.98; p=0.033), stage IIIB or IV disease (HR=0.68, 95% CI 0.57 to 0.82; p=0.000) and no history of smoking (HR=0.48, 95% CI 0.32 to 0.71; p=0.000). The incidence of grade 3/4 adverse events such as rash and diarrhoea was higher in the combination group than in the monotherapy group.

Conclusions

The addition of bevacizumab to erlotinib can significantly improve PFS and the ORR in the second-line treatment of NSCLC with an acceptable and manageable risk of rash and diarrhoea. Further well-conducted, large-scale trials are needed to validate these findings.
Investigating the relationship between substance use and sexual behaviour in young people in Britain: findings from a national probability survey
Authors: Khadr S N , Jones K G , Mann S , Hale D R , Johnson A M , Viner R M , Mercer C H , Wellings K
Published: July 2016

Background

Health risk behaviours are prominent in late adolescence and young adulthood, yet UK population-level research examining the relationship between drug or alcohol use and sexual health and behaviour among young people is scarce, despite public health calls for an integrated approach to health improvement. Our objective was to further our understanding of the scale of and nature of any such relationship, using contemporary data from Britain's third National Survey of Sexual Attitudes and Lifestyles (Natsal-3).

Methods

Analyses of data from Natsal-3, a stratified probability survey of 15 162 men and women (3869 aged 16–24 years), undertaken in 2010–2012, using computer-assisted personal interviewing, were carried out. Logistic regression was used to explore associations between reporting (1) frequent binge drinking (≥weekly), (2) recent drug use (within past 4 weeks) or (3) multiple (both types of) substance use, and key sexual risk behaviours and adverse sexual health outcomes. We then examined the sociodemographic profile, health behaviours and attitudes reported by ‘risky’ young people, defined as those reporting ≥1 type of substance use plus non-condom use at first sex with ≥1 new partner(s), last year.

Results

Men and women reporting frequent binge drinking or recent drug use were more likely to report: unprotected first sex with ≥1 new partner(s), last year; first sex with their last partner after only recently meeting; emergency contraception use (last year) and sexually transmitted infection diagnosis/es (past 5 years). Associations with sexual risk were frequently stronger for those reporting multiple substance use, particularly among men. The profile of ‘risky’ young people differed from that of other 16–24 years old.

Conclusions

In this nationally representative study, substance use was strongly associated with sexual risk and adverse sexual health outcomes among young people. Qualitative or event-level research is needed to examine the context and motivations behind these associations to inform joined-up interventions to address these inter-related behaviours.

The sodium–calcium exchanger (NCX) is considered as the major transmembrane transport mechanism that controls Ca2+ homeostasis. Its contribution to the cardiac repolarization has not yet been directly studied due to lack of specific inhibitors, so that an urgent need for more selective compounds. In this study, the electrophysiological effects of GYKB-6635, a novel NCX inhibitor, on the NCX, L-type calcium, and main repolarizing potassium currents as well as action potential (AP) parameters were investigated. Ion currents and AP recordings were investigated by applying the whole-cell patch clamp and standard microelectrode techniques in canine heart at 37 °C. Effects of GYKB-6635 were studied in ouabain-induced arrhythmias in isolated guinea-pig hearts. At a concentration of 1 μmol/L, GYKB significantly reduced both the inward and outward NCX currents (57% and 58%, respectively). Even at a high concentration (10 μmol/L), GYKB-6635 did not change the ICaL, the maximum rate of depolarization (dV/dtmax), the main repolarizing K+ currents, and the main AP parameters. GYKB-6635 pre-treatment significantly delayed the time to the development of ventricular fibrillation (by about 18%). It is concluded that GYKB-6635 is a potent and highly selective inhibitor of the cardiac NCX and, in addition, it is suggested to also contribute to the prevention of DAD-based arrhythmias.
Radar cross-section reduction based on an iterative fast Fourier transform optimized metasurface
Authors: Song Yi-Chuan , Ding Jun , Guo Chen-Jiang , Ren Yu-Hui , Zhang Jia-Kai
Published: July 2016

A novel polarization insensitive metasurface with over 25 dB monostatic radar cross-section (RCS) reduction is introduced. The proposed metasurface is comprised of carefully arranged unit cells with spatially varied dimension, which enables approximate uniform diffusion of incoming electromagnetic (EM) energy and reduces the threat from bistatic radar system. An iterative fast Fourier transform (FFT) method for conventional antenna array pattern synthesis is innovatively applied to find the best unit cell geometry parameter arrangement. Finally, a metasurface sample is fabricated and tested to validate RCS reduction behavior predicted by full wave simulation software Ansys HFSS[Formula: see text] and marvelous agreement is observed.
FIRST-PRINCIPLE INVESTIGATION ON THE BONDING MECHANISM OF THE SILICON PARTICLES ON THE COPPER FOIL IN COLD SPRAYING
Authors: SONG JUN , LIU JUANFANG , CHEN QINGHUA
Published: July 2016

For lithium–ion batteries, the composite silicon-based electrodes can prevent from losing electrical contact and hence retain the capacity over many cycles. To uncover the adhesion mechanism on the interface formed by the copper foil and the thin silicon coatings during the cold gas dynamic spraying (CGDS) at the microscopic level, the first-principle calculations are performed to investigate the interface properties between them. The ideal work of adhesion, fracture toughness and the interface electronic properties are analyzed. It is found that all the atoms on the interface have vertical displacements, and covalent and ionic bonds are formed between the interfacial Cu and Si atoms which increases the bonding strength. However, the ideal work of adhesion on the interface is lower than one of the Cu bulk and Si bulk, so that fracture would be easier to take place on the interface.

We also develop hypergeometric point count formulas for all odd primes using McCarthy’s [Formula: see text]-adic hypergeometric function. Furthermore, we investigate the relationship between certain period integrals of these surfaces and the trace of Frobenius over finite fields. We extend this work to higher dimensional Dwork hypersurfaces.
Towards a nationwide geological survey in nineteenth century Mexico
Authors: Azuela Luz Fernanda
Published: July 2016

Throughout the nineteenth century, geological research in Mexico was conducted by various actors, including scientific travellers, mining entrepreneurs, civil servants, scientists and amateur geologists. They explored vast swaths of Mexican territory, producing maps and writing articles and books about its geological constitution. However, it was not until the last third of the nineteenth century that any official attempt was made to put together a national geological survey. The French Expedition (1864–67) was the first to assert the need for a general geological map. Later, the Mexican Geological Commission was established in 1888 during the Porfirio Díaz administration. A couple of years later, the first general geological map was finally ready. Research then continued to grow and prosper under the auspices of the National Geological Institute, founded in 1891.
Anticancer Activities of Protopanaxadiol‐ and Protopanaxatriol‐Type Ginsenosides and Their Metabolites
Authors: Chen Xiao-Jia , Zhang Xiao-Jing , Shui Yan-Mei , Wan Jian-Bo , Gao Jian-Li
Published: July 2016

Recently, most anticancer drugs are derived from natural resources such as marine, microbial, and botanical sources, but the low success rates of chemotherapies and the development of multidrug resistance emphasize the importance of discovering new compounds that are both safe and effective against cancer. Ginseng types, including Asian ginseng, American ginseng, and notoginseng, have been used traditionally to treat various diseases, due to their immunomodulatory, neuroprotective, antioxidative, and antitumor activities. Accumulating reports have shown that ginsenosides, the major active component of ginseng, were helpful for tumor treatment. 20(S)‐Protopanaxadiol (PDS) and 20(S)‐protopanaxatriol saponins (PTS) are two characteristic types of triterpenoid saponins in ginsenosides. PTS holds capacity to interfere with crucial metabolism, while PDS could affect cell cycle distribution and prodeath signaling. This review aims at providing an overview of PTS and PDS, as well as their metabolites, regarding their different anticancer effects with the proposal that these compounds might be potent additions to the current chemotherapeutic strategy against cancer.
Absence of Basal Cell Carcinoma in Irradiated Childhood Cancer Survivors of Black Race: A Report from the St. Jude Lifetime Cohort Study
Authors: Ehrhardt Matthew J. , Bhakta Nickhill , Liu Qi , Yasui Yutaka , Krasin Matthew J. , Mulrooney Daniel A. , Hudson Melissa M. , Robison Leslie L.
Published: July 2016

Background: Cancer survivors exposed to therapeutic radiation are at increased risk for basal cell carcinoma (BCC). Despite the notable influence of race on rates of BCC in the general population, the same is not clearly defined in previously irradiated cancer survivors. We investigated the influence of race on the development of BCC in adult survivors of childhood cancer.

Methods: Using a retrospective cohort study, outcomes were collected through June 30, 2015, for 1,746 irradiated childhood cancer survivors participating in the St. Jude Lifetime Cohort Study (SJLIFE), comprising a total of 33,147 person-years of follow-up. Subsequent neoplasms identified in survivors through self-report and prospective clinical assessment were validated by pathology reports. Expected numbers of each type of radiation-associated neoplasm, including BCC, were calculated for irradiated black survivors based on rates in irradiated white survivors, accounting for primary cancer diagnosis, diagnosis year, attained age, and sex.

Results: On the basis of the rate of BCC in previously irradiated white survivors, 56.1 BCCs were expected among 237 black survivors, yet none observed. In contrast, the observed-to-expected ratio of non-BCC radiation-associated neoplasms (melanoma, brain, breast, thyroid cancer) was 0.88 (30 observed/34.2 expected, 95% confidence interval, 0.59–1.25).

Conclusions: We identified an unexpected absence of BCC in irradiated black survivors in SJLIFE. We observe a similar absence of BCC in black individuals among two additional cohorts treated with irradiation for childhood cancer.

Impact: Black survivors are at a substantially reduced or absent risk for BCC from therapeutic radiation for reasons not yet fully understood. Cancer Epidemiol Biomarkers Prev; 25(9); 1356–60. ©2016 AACR.

A Overlapping Carrier Based SPWM for a 5-Level Cascaded H-bridge Multilevel Inverter
Authors: D. Teryima Kureve , Y. Nentawe Goshwe , O. David Agbo
Published: July 2016

This paper proposes a switching control for a cascaded H-bridge inverter structure with reduced switches which is used to improve the THD performance of a single phase five level CHB MLI. The multi level inverter is simulated for the conventional carrier overlapping APOD and the proposed carrier overlapping APOD Pulse Width Modulation (PWM) switching control technique. The total harmonic distortion (THD) of the output voltages are observed for both PWM control techniques. The performance of the symmetric CHB MLI is simulated using MATLAB-SIMULINK. It is observed that the proposed carrier overlapping APODPWM provides output with relatively low THD as compared to the conventional carrier overlapping APODPWM.

Published: July 2016

This paper presents the simulation and experimental of Class-E power amplifier which consists of a load network and a single transistor. The transistor is operated as a switch at the carrier frequency of the output signal. In general, Class-E power amplifier is often used in designing a high frequency ac power source because of its ability to satisfy the zero voltage switching (ZVS) conditions efficiently even when working at high frequencies with significant reduction in switching losses. In this paper, a 10W Class-E power amplifier is designed, constructed, and tested in the laboratory. SK40C microcontroller board with PIC16F877A is used to generate a pulse width modulation (PWM) switching signal to drive the IRF510 MOSFET. To be specific, in this paper, the effect on switching and performance at 1MHz frequency are studied in order to understand the Class-E inverter behavior. Performance parameters relationships were observed and analysed in respect to the load and duty cycle. Theoretical calculations, simulation and experimental results for optimum operation using selected component values are then compared and presented.

Harmonics Reduction in a Current Source Fed Quasi-Resonant Inverter Based Induction Heater
Authors: Chakraborty Avijit , Nag Titas Kumar , Sadhu Pradip Kumar , Pal Nitai
Published: July 2016

This paper investigates an approach to reduce the injection of unwanted harmonics from the input side power source. The proposed work finds an application of a suitably designed Low Pass Filter (LPF) for harmonics reduction. The Low Pass Filter is incorporated in between the input power source and high frequency current source fed single switch parallel quasi-resonant inverter of a domestic Induction Heater. The inverter has an Insulated Gate Bipolar Junction Transistor (IGBT) switch. Undesirable harmonics injection to the input power source makes voltage and current waveforms non-sinusoidal. Fast Fourier Transform (FFT) analysis has been applied to study the effect of harmonics in frequency domain. The entire system is realized in Power System Simulator (PSIM) environment. It is finally proved that the proposed filter reduces the Total Harmonic Distortion (THD) and the Distortion Factor (DF) of the input current. It is also proved that the proposed Low Pass Filter can make the input power factor closer to unity.
A Novel High Gain SEPIC Converter with the Tapped Inductor Model Operating in Discontinuous Conduction Mode for Power Factor Correction
Authors: S Sathiyamoorthy , M Gopinath
Published: July 2016

Power Factor Correction (PFC) has become one of the most active research areas in the field of power electronics due to the surplus power required for various industrial applications around the world. In this work, a novel SEPIC converter with the Tapped Inductor model operating in Discontinuous Conduction Mode (TI-SEPIC- DCM) is proposed for PFC. The proposed TI-SEPIC-DCM improves the voltage gain through voltage multiplier cell and charge pump circuit. The voltage multiplier cell also helps in attaining the Zero-Voltage Switching (ZVS) and Zero-Current Switching (ZCS), which results in higher switching frequency and size reduction. Moreover, a third order harmonic reduction control loop has been proposed for better harmonic mitigation. The proposed work has been simulated in MATLAB and the results are obtained to validate the significance of the proposed TI-SEPIC- DCM with near unity power factor and reduced harmonics.

Published: July 2016

Wireless power transfer (WPT) is a non-contact power transfer within a distance.  With the advantage of not-contact concept, WPT enhances the flexibility movement of the devices.  Basically, there are three types of the WPT which are inductive power transfer (IPT), Capacitive Power Transfer (CPT) and Acoustic Power Transfer (APT).  Among these, capacitive power transfer (CPT) has the advantages of confining electric field between coupled plates, metal penetration ability and also the simplicity in circuit topologies.  Therefore, we focus on the capacitive method in this paper.  To be specific, this paper aims to develop a wireless mouse charging system using capacitive based method. This method enables wireless power transmission from mouse pad to a wireless mouse.  Hence, no battery requires to power up the mouse.  In this paper, a high efficiency Class-E converter is described in details to convert the DC source to AC and the compensation circuit of resonant tank is also proposed at the transmitter side in order to improve the efficiency. In the end, a prototype is developed to prove the developed method.  The performances analysis of the developed prototype is discussed and the future recommendation of this technique is also presented.

It consisted of a PMSG, a DFIG, and a converter and should be operated in the off-grid configuration. In a previous research, the DFIG stator voltages couldn’t be controlled. In this paper, the novel control algorithm that is able to maintain the DFIG stator voltages of the autonomous micro hydro power plant in the off-grid configuration is proposed. The control algorithm was proposed to use the actual DFIG stator voltages and currents as feedback signals. The controller was tested by varying three input signals, i.e. the DC-link voltage, the DFIG stator voltage reference, and the external stator load which simulated the off-grid configuration. The result of the simulation showed that the DFIG stator voltages could be controlled and were always in accordance with the reference.

O artigo aproxima dois materiais - o filmes Os inconfidentes, de Joaquim Pedro de Andrade, de 1972 e o livro K., relato de uma busca, de Bernardo Kucinski, de 2014 - ao redor de uma ideia de escritura do trauma. Filme e livro, cada um a seu modo e em um tempo histórico distinto, lidam com a escritura possível de uma época traumática, a ditadura civil-militar brasileira.
Luís Saia, arquiteto (1911-1975): a descoberta, estudo e restauro das “moradas paulistas”
Authors: Trindade Jaelson Bitran
Published: July 2016

Em 1939, o arquiteto Luís Saia iniciou no Brasil os primeiros restauros completos de edifícios: construções em taipa de pilão, raros remanescentes do século XVII e princípios do XVIII na região de São Paulo. Suas realizações nesse campo têm marcas do “restauro reconstrutivo” e posicionamentos aproximados às formulações dos italianos Gustavo Giovannoni, Roberto Pane e Cesare Brandi. Saia se destacou no Instituto do Patrimônio Histórico e Artístico Nacional (criado em 1937), pelo rigor teórico e metodológico, visão global e crítica e dedicação aos estudos históricos. Este artigo foca nos seus estudos e intervenções de restauro e nas inconsistências das críticas feitas a ele ulteriormente.

A partir de 1944, o ainda estudante Luís Saia, ocupando o cargo oficialmente de Assistente Técnico da 6o Região do Sphan, inicia uma fase profissional de intensa produção prática e teórica relacionada a um grupo de casas rurais então conhecidas como “casas grandes dos arredores de São Paulo”. Neste processo, destaque para o início das intervenções na capela do sítio Santo Antônio no município de São Roque – São Paulo, e a elaboração do artigo “Notas sobre a arquitetura rural paulista do segundo século”, trabalhos que, através de uma análise específica, nos apontarão sutis imprecisões.

O desenvolvimento neuropsicomotor (DNPM) envolve as áreas motoras e cognitivas e é influenciado por questões do ambiente e da tarefa, o que numa visão ampliada de saúde pode ser classificado por meio da Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF). O objetivo deste estudo foi avaliar o DNPM de escolares e classificá-los de acordo com a CIF. Participaram do estudo 22 pré-adolescentes (10 a 12 anos) de ambos os sexos, na região metropolitana de Curitiba, avaliados por meio da Bateria Psicomotora de Fonseca, Medida da independência funcional, entrevista semiestruturada e check-list da CIF para crianças e jovens (CIF-CJ). Observou-se que a maioria dos estudantes não apresentou alterações no DNPM, e que o auto-relato identificou: mudança no modelo familiar, poucas possibilidades para esporte e lazer, preferência pelas brincadeiras como entretenimento, escola como ambiente predominante, boa autopercepção de saúde, dificuldade de acessibilidade. Além disso, identificou-se uma criança com atraso em fatores psicomotores isolados, mas com bom desempenho psicomotor geral. A utilização do modelo proposto pelos autores respondeu às dimensões da CIF, indicando sua aplicabilidade e possibilidades de uso em ambiente escolar.
Intervenção domiciliar com ênfase no autocuidado para idosos usuários de um Centro de Saúde Escola do Município de São Paulo
Authors: Almeida Maria Helena Morgani de , Batista Marina Picazzio Perez
Published: July 2016

Introdução: Segundo a Organização Mundial da Saúde, riscos para declínio de saúde, funcionalidade e morte de idosos incluem ser mulher solteira ou viúva, ter 80 anos ou mais, estar isolado, ter limitações em atividades diárias básicas. Objetivo: Descrever e analisar intervenção de terapia ocupacional a idosos sob dois ou mais riscos.  Método: Pesquisa intervenção desenvolvida em 2008/2009 em três etapas: avaliação com o Instrumento de Classificação de Idosos quanto à Capacidade para o Autocuidado; orientações para funcionalidade, universo ocupacional e interação social; reavaliação. Critérios de inclusão: ser idoso; sob risco demográfico (por ter 80 anos ou mais e/ou ser mulher solteira ou viúva), e social e/ou funcional (segundo pesquisa de 2006/2008); usuário do Centro de Saúde Escola Geraldo Paula Souza da FSP/USP. Resultados: Participaram 58 idosos que adotavam práticas de autocuidado, mas não efetivas. Esses foram orientados quanto a modificações nas atividades e no ambiente e a ampliarem da rede de suporte; 25,9% ampliaram universo ocupacional, 32,8% aumentaram rede, e houve discreta melhora funcional. Um maior número de idosos com dificuldades funcionais passou a morar com alguém e a contar com ajuda.  Conclusão: A intervenção foi benéfica para ampliar atividades, rede de suporte e melhorar funcionalidade.
A INTERFACE INSTITUCIONAL ENTRE A ANS E O PODER JUDICIÁRIO: ANÁLISE DE ACÓRDÃOS SOBRE A COBERTURA DE EMERGÊNCIAS MÉDICAS EM PLANOS DE SAÚDE
Authors: Ramalho Bruno Araujo
Published: July 2016

O presente artigo dedica-se a analisar o controle judicial da norma regulatória atualmente adotada pela Agência Nacional de Saúde Suplementar (ANS) para a cobertura de urgências e emergências médicas em planos de assistência à saúde. Para tanto, foi feita uma revisão jurisprudencial de acórdãos dos tribunais de São Paulo, Rio de Janeiro e Minas Gerais que versavam sobre o tema e, ao final, verificou-se que a norma regulatória tem sido considerada ilegal pela maioria dos integrantes desses tribunais (com exceção de uma Câmara Cível específica do Tribunal de São Paulo). Os resultados da revisão jurisprudencial foram discutidos tomando-se por base o grau de vinculação à juridicidade e destacando-se os problemas epistêmicos existentes atualmente para a caracterização de uma urgência médica, bem como para a definição do alcance a ser dado na cobertura desta natureza. Na conclusão da pesquisa, demonstrou-se haver a necessidade de um melhor paradigma regulatório e de uma harmoniosa interface institucional entre a agência reguladora e o Poder Judiciário.

Um espectro ronda a selva: história, antropologia e práxis
Authors: Velloso Gustavo
Published: July 2016

(primeiro parágrafo da resenha)O livro Marx Selvagem, de Jean Tible, reconduz para a arena das ciências humanas um horizonte analítico que vinha sendo desdenhado há décadas, depois de ter se beneficiado do contexto teórico e político particularmente favorável do início do século XX até os anos 1980, em todo o mundo. Trata-se do aproveitamento do materialismo histórico, enquanto tradição de análises e reflexões, para o estudo de formações sociais diferentes daquela que constituiu o eixo central das preocupações de seus primeiros pensadores, isto é, a sociedade capitalista em seu clássico formato industrial. No caso, as populações indígenas do continente americano são o foco da reflexão.
Em plena guerra: imprensa, catolicismo e política nas duas primeiras décadas do século XX
Authors: Almeida Claudio Aguiar
Published: July 2016

Nas duas primeiras décadas do século XX, impedidos de criar um partido inspirado no Deutsche Zemtrumspartei, os católicos de Vozes de Petrópolis e do Centro da Boa Imprensa investiram na criação de periódicos e instituições culturais que contribuíssem para a “recristianização” do Estado brasileiro. Este artigo aborda um momento decisivo do processo de construção desse projeto analisando, dentre outras fontes, a revista Vozes de Petrópolis e os ensaios A caricatura na imprensa brasileira e Em plena guerra de frei Pedro Sinzig.
Living in a Japanese onsen: field observations and physiological measurements of hot spring amphibian tadpoles, Buergeria japonica
Authors: Komaki Shohei , Lau Quintin , Igawa Takeshi
Published: July 2016

The Japanese stream tree frog,Buergeria japonica, is widely distributed across the southern islands of Japan and Taiwan. While the species is known to inhabit hot springs, this has only been reported in Taiwan. To further understand the utilization of hot springs byB. japonica, we conducted field observations of tadpoles from a hot spring on Kuchinoshima Island, a tiny volcanic island of southwestern Japan. We found that tadpoles on Kuchinoshima Island inhabited hot spring pools with extremely high temperatures that exceeded temperatures in which any other amphibians have been found. In addition, we conducted thermal tolerance measurements and found that the thermal tolerance ofB. japonicatadpoles was high. These findings suggest that high thermal tolerance ofB. japonicais maintained even at the northern tip of its distribution, and this has allowed them to widen their available niche and inhabit a hot spring on the tiny island of Kuchinoshima.
Serbia’s Action against Transnational Organised Crime
Authors: Obokata Tom , Boskovic Aleksandar , Radovic Nenad
Published: July 2016

This article examines the extent to which Serbia has implemented relevant international standards on action against transnational organised crime contained in the United Nations Convention against Transnational Organised Crime 2000. The first part explores key obligations with particular reference to prohibition of substantive offences, intelligence-led law enforcement (special investigative techniques), confiscation of criminal proceeds, as well as international law enforcement cooperation. The second part of the article analyses how these obligations are implemented by Serbia in reality by examining legislative frameworks as well as law enforcement practices. The main conclusion is that, while Serbia has taken some steps to implement international standards with a view to enhancing individual and collective actions against transnational organised crime, effective law enforcement is hampered by issues such as corruption and a lack of expertise, experience and resources.
A Behind-the-Scenes Glimpse into the Princeps Edition of Colóquios dos simples (Goa, 1563)
Authors: Nobre de Carvalho Teresa
Published: July 2016

Considered by many to be the most learned Portuguese physician who lived in Goa during the sixteenth century, Garcia de Orta (c. 1500–1568) was the author of Colóquios dos Simples, e Drogas he cousas mediçinais da India [Colloquies on the Simples and Drugs of India] (Goa, 1563). Devoted entirely to the description of Asian natural resources, very little is known about how this treatise came into existence. Published at the edges of the Portuguese empire, and a hostage to technical, structural and human constraints, the princeps edition had a limited circulation. The diffusion around Europe of the novelties described in Colóquios dos Simples owed in part to the efforts of Clusius (1526–1609), one of the leading botanists of the time. This scholar promptly published Aromatum et Simplicium (Antwerp, 1567), a Latin epitome of Colóquios dos Simples. This complete reframing of Orta’s treatise guaranteed the wide dissemination of the new knowledge about Asian plants, fruits and drugs validated by the Portuguese physician on the periphery of the empire. 

In this essay I analyse the background to the publication of the Portuguese treatise and demonstrate that, especially due to structural constraints, the princeps edition had a limited circulation. I show that the wide diffusion of the novelties about the natural resources of the Indies was dependent on the technical equipment, artistic skills and editorial criteria dictated and managed by European academics, artists and printers. I propose that the appropriation of local knowledge collected and validated in the Iberian Empires by imperial agents challenged European academics and typographers to create innovative treatises about the Indies’ natural resources that assured the widespread circulation of an entirely new natural knowledge.
