Objetivo: Apreender as práticas comumente desenvolvidas na estratégia saúde da família durante o pré-natal e quais os profissionais envolvidos nessa dinâmica. Métodos: Realizou-se uma revisão integrativa da literatura com abrangência temporal entre os anos de 2001 e 2012, nas bases de dados SciELO e no Portal de Periódicos CAPES a partir dos descritores: saúde da mulher, cuidado pré-natal e pessoal de saúde. Resultados: Observou-se que alguns artigos enfatizam o trabalho do enfermeiro em detrimento ao trabalho multidisciplinar o que desvela a dificuldade na integração das práticas em equipe e que o foco da assistência é quase exclusivamente de caráter técnico, sendo demonstrado que os aspectos mais relevantes para a qualidade das ações durante o pré-natal são referentes ao número de consultas, exames e vacinas. Conclusão: É imprescindível que os profissionais de saúde trabalhem na perspectiva da multidisciplinaridade, na qual o cuidado prestado a gestante aconteça de forma integral e complementar.

Objetivo: identificar as taxas de geração de resíduos do serviço de saúde (kg.leito-1.dia-1) para os grupos de resíduos A, B, D (incluindo os recicláveis) e E, verificar a influência da sazonalidade na geração de resíduos. Metodologia: os dados foram coletados através de pesagens desses resíduos, durante sete dias consecutivos, em quatro semanas, sendo que cada semana contemplou uma estação do ano. Resultados: a taxa de geração de resíduos apresentou os seguintes valores em kg.leito-1.dia-1 para cada grupo: A: 0,831, B: 0,088, D: 2,607, D-Recicláveis: 0,525 e E: 0,102. Através do teste ANOVA nã5o foram encontradas evidências de que haja influência da sazonalidade na geração dos resíduos. Conclusões: hospitais com número de leitos semelhantes apresentam taxas de geração de resíduos diferentes, portanto não foi possível utilizar uma taxa de geração de referência para comparação com outros hospitais. Ainda, o teste ANOVA não indicou que a sazonalidade influencia a geração de resíduos.
Subducted sediment thickness and Mw 9 earthquakes
Authors: Seno Tetsuzo 
Published: January 2017

AbstractI measure the thickness of subducted sediment (Δss) beneath the décollement in the fore‐arc wedge and show that the average value of Δss over a subduction zone segment (
) is greater than 1.3 km in segments where Mw ≥ 9 earthquakes have occurred and less than 1.2 km in segments without such large earthquakes. In a previous study, I showed that the stress drop (Δσ) of large earthquakes (Mw ≥ 7) averaged over a subduction zone segment (
) is larger in segments where Mw ≥ 9 earthquakes have occurred than in segments without such an event. It has also been shown that
is linearly related to 1 − λ (λ = the pore fluid pressure ratio in the interplate megathrust). In this study, I revise the previous estimates of
and λ and show that there is a positive correlation between
,
, and 1 − λ. I present a model that relates Δss to 1 − λ based on the porous flow of H2O in the subducted sediments, which gives a theoretical basis for the correlation between
and
. The combination of these parameters thus provides a better indicator for identifying segments where Mw ≥ 9 earthquakes may occur. Based on this, I propose that the tectonic environments where such huge events are likely to occur are (1) near collision zones, (2) near subduction of spreading centers, and (3) erosive margins with compressional fore arcs. Near the Japanese islands, SE Hokkaido is prone to such an event, but the Nankai Trough is not.
Direct estimates of friction factors for a mobile rippled bed
Authors: Rodríguez‐Abudo S. , Foster D. L. 
Published: January 2017

AbstractNew friction factor estimates are computed from the total momentum transfer applied to a rippled sediment bed. The total time‐dependent momentum flux is achieved by implementing the double‐averaged horizontal momentum equation on the nearbed flow field collected with PIV. Time‐independent friction factors are obtained by regressing the total momentum flux to the common quadratic stress law given by. The resulting friction factors compare favorably with available analysis techniques including energy dissipation, vertical turbulence intensity, and maximum shear stress, but can be 2‐6 times smaller than estimates determined with the model byMadsen (1994)and the formula ofSwart (1974)using the ripple roughness.
Construction of Tertiary Amides: NiII‐Catalyzed N‐Arylation of Secondary Acyclic Amides (2‐Picolinamides) with Aryl Halides
Authors: Sankar Rathinam , Babu Srinivasarao Arulananda 
Published: January 2017

AbstractNiII‐catalyzed C−N cross‐coupling reaction of secondary acyclic amides (2‐picolinamides, which were derived from 2‐picolinic acid and amines) and aryl halides for the construction of tertiary amides has been reported. Relatively inexpensive NiCl2 was used as the catalyst for the N‐arylation of various 2‐picolinamides (secondary acyclic amides), in which the 2‐picolinamide unit plausibly served as an internal ligand.

Published: January 2017

AbstractMetal–amine solutions provide a unique arena in which to study electrons in solution, and to tune the electron density from the extremes of electrolytic through to true metallic behavior. The existence and structure of a new class of concentrated metal‐amine liquid, Li–NH3–MeNH2, is presented in which the mixed solvent produces a novel type of electron solvation and delocalization that is fundamentally different from either of the constituent systems. NMR, ESR, and neutron diffraction allow the environment of the solvated electron and liquid structure to be precisely interrogated. Unexpectedly it was found that the solution is truly homogeneous and metallic. Equally surprising was the observation of strong longer‐range order in this mixed solvent system. This is despite the heterogeneity of the cation solvation, and it is concluded that the solvated electron itself acts as a structural template. This is a quite remarkable observation, given that the liquid is metallic.
A Vesicle‐to‐Worm Transition Provides a New High‐Temperature Oil Thickening Mechanism
Authors: Derry Matthew J. , Mykhaylyk Oleksandr O. , Armes Steven P. 
Published: January 2017

AbstractDiblock copolymer vesicles are prepared via RAFT dispersion polymerization directly in mineral oil. Such vesicles undergo a vesicle‐to‐worm transition on heating to 150 °C, as judged by TEM and SAXS. Variable‐temperature 1H NMR spectroscopy indicates that this transition is the result of surface plasticization of the membrane‐forming block by hot solvent, effectively increasing the volume fraction of the stabilizer block and so reducing the packing parameter for the copolymer chains. The rheological behavior of a 10 % w/w copolymer dispersion in mineral oil is strongly temperature‐dependent: the storage modulus increases by five orders of magnitude on heating above the critical gelation temperature of 135 °C, as the non‐interacting vesicles are converted into weakly interacting worms. SAXS studies indicate that, on average, three worms are formed per vesicle. Such vesicle‐to‐worm transitions offer an interesting new mechanism for the high‐temperature thickening of oils.

AbstractFive hexanuclear lanthanide clusters of composition [Ln6(μ4‐O)2(HCOO)2L4(HL′)2(dmf)2] [Ln=Dy (1), Er (2), Ho (3), Tb (4), Gd (5); H2L=2‐{[2‐(hydroxymethyl)phenylimino]methyl}‐6‐methoxyphenol; H3L′=3‐{[2‐(hydroxymethyl)phenylimino]methyl}benzene‐1,2‐diol; H3L′ was derived in situ from the H2L ligand] were prepared under solvothermal conditions. The [Ln6] cores of 1–5 possess an unprecedented motif, namely, two tetrahedron Ln4 units sharing an edge and two vertices. The six LnIII ions of 1–5 are connected through two μ4‐O anions. Magnetic susceptibility studies reveal that complex 1 exhibits frequency dependence of the alternating current susceptibility typical of single‐molecule magnets. Complex 1 possesses a relatively large energy barrier of 85 K among all of the reported Dy6 single‐molecule magnets.

Published: January 2017

AbstractSignificant progress has been made on the synthesis and application of mesoporous γ‐alumina. To date, little attention has been paid to the synthesis of microporous crystalline alumina. Here, fabrication of microporous crystalline γ‐alumina using a microporous covalent triazine framework (CTF‐1) as a template is described. Microporous crystalline γ‐alumina with a micro‐meso binary pore system was replicated by infiltration of aluminum nitrate into the micropores of the CTF‐1 template through a NH3/water‐vapor‐induced internal hydrolysis method, followed by thermal treatment, and subsequent removal of the CTF‐1 template with a 30 % H2O2 aqueous solution. The obtained crystalline γ‐alumina material exhibits a large surface area (349 m2 g−1) with micropore distribution centered at about 1.27 nm. Ru supported on microporous γ‐Al2O3 can be employed as catalyst for hydrolytic dehydrogenation of ammonia borane, and it exhibits high catalytic activity and good durability. This finding provides a new benchmark for preparing well‐defined crystalline microporous alumina materials by a template method, which can be applied in a wide range of fields.

Vibrational Spectrum of an Excited State and Huang–Rhys Factors by Coherent Wave Packets in Time‐Resolved Fluorescence Spectroscopy
Authors: Lee Gyeongjin , Kim Junwoo , Kim So Young , Kim Dong Eon , Joo Taiha 
Published: January 2017

AbstractCoherent nuclear wave packet motions in an electronic excited state of a molecule are measured directly by time‐resolved spontaneous fluorescence spectroscopy with an unprecedented time resolution by using two‐photon absorption excitation and fluorescence upconversion by noncollinear sum frequency generation. With an estimated time resolution of approximately 25 fs, wave packet motions of vibrational modes up to 1600 cm−1 are recorded for coumarin 153 in ethanol. Two‐color transient absorption at 13 fs time resolution are measured to confirm the result. Vibrational displacements between the ground and excited states and Huang–Rhys factors (HRFs) are calculated by quantum mechanical methods and are compared with the experimental results. HRFs calculated by density functional theory (DFT) and time‐dependent DFT reproduce the experiment adequately. This fluorescence‐based method provides a unique and direct way to obtain the vibrational spectrum of a molecule in an electronic excited state and the HRFs, as well as the dynamics of excited states, and it might provide information on the structure of an excited state through the HRFs.
Environmental and Excitation Power Effects on the Ratiometric Upconversion Luminescence Based Temperature Sensing Using Nanocrystalline NaYF4:Yb3+,Er3+

Published: January 2017

AbstractThe luminescence intensity ratio (LIR) of the green emissions of the near‐infrared excited NaYF4:Yb3+,Er3+ nanocrystals is a promising method for temperature sensing. Here, the influence of excitation power density, excitation pulse length, excitation wavelength, silica shell, and solvent on the LIR and its temperature response is reported. The primary objective is to study the LIR mechanism and the impact of measurement and environmental parameters on the calibration and precision of the LIR. The LIR value is demonstrated to be unaffected by the excitation intensity in the studied range. This result is essential, considering the application feasibility of the LIR method as temperature sensor, where the effective excitation power density depends on the sample matrix and the distance excitation light travels in the sample. The pulsed excitation, however, results in an increase in the LIR value upon short pulse width. Silanization of bare nanocrystals has no effect on the LIR values, but the local warming of H2O samples under laser exposure results in slightly increased LIR values compared to other solvents; D2O, oleic acid, and dimethyl sulfoxide. The thermal quenching of luminescence lifetimes of Er3+ emission is proved to be too weak for sensing applications.

Solvent‐Adaptive Behavior of Oligospirobifluorenes at the Surface of Quartz Crystal Microbalances—A Conformational Process
Authors: Pyka Isabella , Lubczyk Daniel , Saiju Mandira D. S. , Salbeck Josef , Waldvogel Siegfried R. 
Published: January 2017

AbstractOligospirobifluorenes represent promising building blocks for the generation of microporous sensor materials based on their restricted flexibility. The contact with specific solvents leads to a change of the three‐dimensional spirobifluorene structure. The single fluorene moieties unfold to an open structure with an increased volume due to intermolecular interactions with the solvent, detectable by NMR spectroscopy. The induced microporosity was further investigated by affinity comparisons of aromatic analytes with high fundamental frequency quartz crystal microbalances.

Published: January 2017

AbstractSynthesis of asymmetrical organic carbonates from the renewable and inexpensive CO2 is of great importance but also challenging, especially at ambient conditions. Herein, we found that some metal salt/ionic liquid catalyst systems were highly active for the synthesis of asymmetrical organic carbonates from CO2, propargylic alcohols, and primary alcohols. Especially, the AgCl/1‐butyl‐3‐methylimidazolium acetate ([Bmim][OAc]) system was very efficient for the reactions of a wide range of substrates at room temperature and atmospheric pressure, and the yields of the asymmetrical organic carbonates could approach 100 %. The catalyst system could be reused at least five times without changing its catalytic performance, and could be easily recovered and reused. A detailed study indicated that AgCl and [Bmim][OAc] catalyzed the reactions cooperatively, resulting in unique catalytic performance.

Published: January 2017

SummaryLactation may protect women with previous gestational diabetes mellitus (GDM) from developing type 2 diabetes mellitus, but the results of existing studies are inconsistent, ranging from null to beneficial. We aimed to conduct a systematic review to gather available evidence. Databases MEDLINE, CINAHL, PubMed, and EMBASE were searched on December 15, 2015, without restriction of language or publication year. A manual search was also conducted. We included observational studies (cross‐sectional, case‐control, and cohort study) with information on lactation and type 2 diabetes mellitus incidence among women with previous GDM. We excluded case studies without control data. Data synthesis was conducted by random‐effect meta‐analysis. Fourteen reports of 9 studies were included. Overall risk of bias using RoBANS ranged from low to unclear. Longer lactation for more than 4 to 12 weeks postpartum had risk reduction of type 2 diabetes mellitus compared with shorter lactation (OR 0.77, 95% CI 0.01‐55.86; OR 0.56, 95% CI 0.35‐0.89; OR 0.22, 95% CI 0.13‐0.36; type 2 diabetes mellitus evaluation time < 2 y, 2‐5 y, and >5 y, respectively). Exclusive lactation for more than 6 to 9 weeks postpartum also had lower risk of type 2 diabetes mellitus compared with exclusive formula (OR 0.42, 95% CI 0.22‐0.81). The findings support the evidence that longer and exclusive lactation may be beneficial for type 2 diabetes mellitus prevention in women with previous GDM. However, the evidence relies only on observational studies. Therefore, further studies are required to address the true causal effect.
Liana effects on biomass dynamics strengthen during secondary forest succession

Published: January 2017

AbstractSecondary forests are important carbon sinks, but their biomass dynamics vary markedly within and across landscapes. The biotic and abiotic drivers of this variation are still not well understood. We tested the effects of soil resource availability and competition by lianas on the biomass dynamics of young secondary tropical forests in Panama and assessed the extent to which liana effects were mediated by soil resource availability. Over a five‐year period, growth, mortality, and recruitment of woody plants of ≥1 cm diameter were monitored in 84 plots in 3–30‐year‐old secondary forests across the Agua Salud site in central Panama. Biomass dynamics and the effects of lianas and soil resources were examined using (generalized) linear mixed‐effect models and a model averaging approach. There was strong spatial and temporal variation in liana biomass within and across the plots. The relative biomass of lianas had a strong negative effect on overall tree growth, growth of understory trees decreased with soil fertility and dry season soil water content, and the effect of lianas on tree mortality varied with soil fertility. Tree recruitment was not associated with any of the predictor variables. Our model indicates that tree biomass growth across our landscape was reduced with 22% due to competition with lianas, and that the effect of lianas increased during succession, from 19% after five years to 32% after 30 years. The projected liana‐induced growth reduction after 60 years was 47%, which was consistent with data from a nearby site. Our study shows that the observed liana proliferation across tropical forests may reduce the sequestration and storage of carbon in young secondary forests, with important implications for the carbon balance of tropical forest landscapes and consequently for global climate change. Our study highlights the need to incorporate lianas and soil variables in research on the biomass dynamics of secondary forest across tropical landscapes, and the need for well‐replicated longitudinal studies to cover landscape‐level variability in the relevant abiotic and biotic components.
Assimilation of historical head data to estimate spatial distributions of stream bed and aquifer hydraulic conductivity fields
Authors: Alzraiee Ayman H. , Bailey Ryan , Bau Domenico 
Published: January 2017

AbstractManagement of water resources in alluvial aquifers relies mainly on understanding interactions between hydraulically connected streams and aquifers. Numerical models that simulate this interaction often are used as decision support tools for water resource management. However, the accuracy of numerical predictions relies heavily on unknown system parameters (e.g., streambed conductivity and aquifer hydraulic conductivity), which are spatially heterogeneous and difficult to measure directly. This paper employs an ensemble smoother to invert groundwater level measurements to jointly estimate spatially varying streambed and alluvial aquifer hydraulic conductivity along a 35.6‐km segment of the South Platte River in Northeastern Colorado. The accuracy of the inversion procedure is evaluated using a synthetic experiment and historical groundwater level measurements, with the latter constituting the novelty of this study in the inversion and validation of high‐resolution fields of streambed and aquifer conductivities. Results show that the estimated streambed conductivity field and aquifer conductivity field produce an acceptable agreement between observed and simulated groundwater levels and stream flow rates. The estimated parameter fields are also used to simulate the spatially varying flow exchange between the alluvial aquifer and the stream, which exhibits high spatial variability along the river reach with a maximum average monthly aquifer gain of about 2.3 m3/day and a maximum average monthly aquifer loss of 2.8 m3/day, per unit area of streambed (m2). These results demonstrate that data assimilation inversion provides a reliable and computationally affordable tool to estimate the spatial variability of streambed and aquifer conductivities at high resolution in real‐world systems.
