New insights on stellar evolution and stellar interior physics are being made possible by asteroseismology. Throughout the course of the Kepler mission, asteroseismology has also played an important role in the characterization of exoplanet-host stars and their planetary systems. The upcoming NASA Transiting Exoplanet Survey Satellite (TESS) will be performing a near all-sky survey for planets that transit bright nearby stars. In addition, its excellent photometric precision, combined with its fine time sampling and long intervals of uninterrupted observations, will enable asteroseismology of solar-type and red-giant stars. Here we develop a simple test to estimate the detectability of solar-like oscillations in TESS photometry of any given star. Based on an all-sky stellar and planetary synthetic population, we go on to predict the asteroseismic yield of the TESS mission, placing emphasis on the yield of exoplanet-host stars for which we expect to detect solar-like oscillations. This is done for both the target stars (observed at a 2-minute cadence) and the full-frame-image stars (observed at a 30-minute cadence). A similar exercise is also conducted based on a compilation of known host stars. We predict that TESS will detect solar-like oscillations in a few dozen target hosts (mainly subgiant stars but also in a smaller number of F dwarfs), in up to 200 low-luminosity red-giant hosts, and in over 100 solar-type and red-giant known hosts, thereby leading to a threefold improvement in the asteroseismic yield of exoplanet-host stars when compared to Kepler's.

We present multi-epoch mid-infrared (IR) photometry and the optical discovery observations of the “impostor” supernova (SN) 2010da in NGC 300 using new and archival Spitzer
Space Telescope images and ground-based observatories. The mid-infrared counterpart of SN 2010da was detected as Spitzer Infrared Intensive Transient Survey (SPIRITS) 14bme in the SPIRITS, an ongoing systematic search for IR transients. Before erupting on 2010 May 24, the SN 2010da progenitor exhibited a constant mid-IR flux at 3.6 and only a slight ∼10% decrease at 4.5 μm between 2003 November and 2007 December. A sharp increase in the 3.6 μm flux followed by a rapid decrease measured ∼150 days before and ∼80 days after the initial outburst, respectively, reveal a mid-IR counterpart to the coincident optical and high luminosity X-ray outbursts. At late times, after the outburst (∼2000 days), the 3.6 and 4.5 μm emission increased to over a factor of two times the progenitor flux and is currently observed (as of 2016 Feb) to be fading, but still above the progenitor flux. We attribute the re-brightening mid-IR emission to continued dust production and increasing luminosity of the surviving system associated with SN 2010da. We analyze the evolution of the dust temperature (T
d ∼ 700–1000 K), mass (M
d ∼ 0.5–3.8 × 10−7
M
⊙), luminosity (L
IR ∼ 1.3–3.5 × 104
L
⊙), and the equilibrium temperature radius (R
eq ∼ 6.4–12.2 au) in order to resolve the nature of SN 2010da. We address the leading interpretation of SN 2010da as an eruption from a luminous blue variable high-mass X-ray binary (HMXB) system. We propose that SN 2010da is instead a supergiant (sg)B[e]-HMXB based on similar luminosities and dust masses exhibited by two other known sgB[e]-HMXB systems. Additionally, the SN 2010da progenitor occupies a similar region on a mid-IR color–magnitude diagram (CMD) with known sgB[e] stars in the Large Magellanic Cloud. The lower limit estimated for the orbital eccentricity of the sgB[e]-HMXB (e > 0.82) from X-ray luminosity measurements is high compared to known sgHMXBs and supports the claim that SN 2010da may be associated with a newly formed HMXB system.

The millimeter transient sky is largely unexplored, with measurements limited to follow-up of objects detected at other wavelengths. High-angular-resolution telescopes, designed for measurement of the cosmic microwave background (CMB), offer the possibility to discover new, unknown transient sources in this band—particularly the afterglows of unobserved gamma-ray bursts (GRBs). Here, we use the 10 m millimeter-wave South Pole Telescope, designed for the primary purpose of observing the CMB at arcminute and larger angular scales, to conduct a search for such objects. During the 2012–2013 season, the telescope was used to continuously observe a 100 deg2 patch of sky centered at R.A. 23h30m and decl. −55° using the polarization-sensitive SPTpol camera in two bands centered at 95 and 150 GHz. These 6000 hr of observations provided continuous monitoring for day- to month-scale millimeter-wave transient sources at the 10 mJy level. One candidate object was observed with properties broadly consistent with a GRB afterglow, but at a statistical significance too low (p = 0.01) to confirm detection.

We have conducted a near-infrared (NIR) proper motion survey, the Sondage Infrarouge de Mouvement Propre, in order to discover field ultracool dwarfs (UCD) in the solar neighborhood. The survey was conducted by imaging ∼28% of the sky with the Caméra PAnoramique Proche-InfraRouge both in the southern hemisphere at the Cerro Tololo Inter-American Observatory 1.5 m telescope, and in the northern hemisphere at the Observatoire du Mont-Mégantic 1.6 m telescope and comparing the source positions from these observations with the Two Micron All-Sky Survey Point Source Catalog (2MASS PSC). Additional color criteria were used to further discriminate unwanted astrophysical sources. We present the results of an NIR spectroscopic follow-up of 169 M, L, and T dwarfs. Among the sources discovered are 2 young field brown dwarfs, 6 unusually red M and L dwarfs, 25 unusually blue M and L dwarfs, 2 candidate unresolved L+T binaries, and 24 peculiar UCDs. Additionally, we add 9 L/T transition dwarfs (L6–T4.5) to the already known objects.
VISIBLE ABSORPTIONS OF POTENTIAL DIFFUSE ISM HYDROCARBONS: C9H9 AND C9H5 RADICALS
Authors: Steglich M. , Maity S. , Maier J. P.
Published: October 2016

The laboratory detection of previously unobserved resonance-stabilized C9H5 and C9H9 radicals in the supersonic expansion of a hydrocarbon discharge source is reported. The radicals are tentatively assigned as acetylenic-substituted cyclopentadienyl C9H5 and vinyl-substituted benzyl C9H9 species. They are found to feature visible absorption bands that coincide with a few very weak diffuse interstellar bands toward HD183143 and HD204827.

Investigation of the lunar crustal magnetic anomalies offers a comprehensive long-term data set of observations of small-scale magnetic fields and their interaction with the solar wind. In this paper a review of the observations of lunar mini-magnetospheres is compared quantifiably with theoretical kinetic-scale plasma physics and 3D particle-in-cell simulations. The aim of this paper is to provide a complete picture of all the aspects of the phenomena and to show how the observations from all the different and international missions interrelate. The analysis shows that the simulations are consistent with the formation of miniature (smaller than the ion Larmor orbit) collisionless shocks and miniature magnetospheric cavities, which has not been demonstrated previously. The simulations reproduce the finesse and form of the differential proton patterns that are believed to be responsible for the creation of both the “lunar swirls” and “dark lanes.” Using a mature plasma physics code like OSIRIS allows us, for the first time, to make a side-by-side comparison between model and space observations. This is shown for all of the key plasma parameters observed to date by spacecraft, including the spectral imaging data of the lunar swirls. The analysis of miniature magnetic structures offers insight into multi-scale mechanisms and kinetic-scale aspects of planetary magnetospheres.
COMPRESSIBLE FLOW IN FRONT OF AN AXISYMMETRIC BLUNT OBJECT: ANALYTIC APPROXIMATION AND ASTROPHYSICAL IMPLICATIONS
Authors: Keshet Uri , Naor Yossi
Published: October 2016

Compressible flows around blunt objects have diverse applications, but current analytic treatments are inaccurate and limited to narrow parameter regimes. We show that the gas-dynamic flow in front of an axisymmetric blunt body is accurately derived analytically using a low order expansion of the perpendicular gradients in terms of the parallel velocity. This reproduces both subsonic and supersonic flows measured and simulated for a sphere, including the transonic regime and the bow shock properties. Some astrophysical implications are outlined, in particular for planets in the solar wind and for clumps and bubbles in the intergalactic medium. The bow shock standoff distance normalized by the obstacle curvature is

in the strong shock limit, where g is the compression ratio. For a subsonic Mach number M approaching unity, the thickness δ of an initially weak, draped magnetic layer is a few times larger than in the incompressible limit, with amplification

Published: October 2016

Hip preservation surgery encompasses various surgical procedures that have the goal of decreasing the progression of osteoarthritis, preserving normal hip function, and delaying the need for arthroplasty. These procedures can encompass arthroscopic, open, and combined techniques. This study investigated the trends and complications associated with open hip preservation surgery performed by candidates undergoing Part II of the American Board of Orthopaedic Surgery examination. The American Board of Orthopaedic Surgery Part II surgeon case database was queried from the years 2003 to 2013 for Current Procedural Terminology (CPT) codes related to open hip preservation surgery in patients 10 years and older. Patient demographics, fellowship training, geographic location, and complications were extracted from the database. These data were analyzed to determine the incidence by year of individual procedures and complications. During the study period, 644 cases (352 male, 292 female; mean age, 29.7 years) and 730 CPT codes were reported. The most commonly reported fellowship was pediatric orthopedics. No trend was observed in the overall incidence of these surgeries, but there was an increase in the number of cases performed in the Midwest. There were 212 reported complications, with a rate of 33% per case, or 29% per CPT code (range, 12.5%–100% per CPT code). Complications reported ranged from infection to death. The incidence of complications over time showed no discernible trend. Based on the results of this study, the yearly incidence and complications associated with open hip preservation surgery performed by surgeons undergoing board certification should continue at a predictable rate.

Published: October 2016

Is there a correlation between increased posterior-inferior tibial slope angle and noncontact anterior cruciate ligament (ACL) injury? Does increasing the posterior-inferior tibial slope angle increase the risk of bilateral ACL injury? A computerized relational database (Access 2007; Microsoft Inc, Redmond, Washington) was used to conduct a retrospective review of patients undergoing bilateral or unilateral ACL reconstruction surgery or treatment by a single surgeon between 1995 and 2013. Included in the study were patients with bilateral and unilateral ACL injuries and patellofemoral pain syndrome with no associated ACL deficiency. Exclusion criteria included concomitant ligament injury, previous ACL reconstruction, and previous knee surgery. Also excluded were patients who did not have plain lateral radiographs. Fifty patients were randomly selected from each group. After controlling for age and Tegner activity level, the authors found that the posterior-inferior tibial slope angle was a significant predictor (
P
=.002) of noncontact ACL injury. Mean posterior-inferior tibial slope angle for the bilateral, unilateral, and control groups was 11.8°±2.3°, 9.3°±2.4°, and 7.5°±2.3°, respectively. In the group with unilateral ACL injury vs the group without ACL deficiency, a 1° increase in posterior-inferior tibial slope angle (
P
=.03) was associated with a 20% increase in unilateral ACL injury. In those with bilateral ACL injury vs those without ACL deficiency, a 1° increase in posterior-inferior tibial slope angle (
P
=.001) increased bilateral knee injury by 34%. The difference between the mean angles of the control group without ACL deficiency and both the bilateral injury and unilateral injury cohorts was statistically significant (
P
=.003). Increased posterior-inferior tibial slope angle is associated with an increased risk of noncontact bilateral and unilateral ACL injury. [

Published: October 2016

The purpose was to investigate the amount of skeletal and dentoalveolar changes after early treatment of Class II, Division 1 malocclusion with bionator appliance in prepubertal growing patients. Forty Class II patients were divided in two groups. Treated group consisted of 20 subjects treated consecutively with bionator. Mean age at the start of treatment (T0) was 9.1 years, while it was 10.6 years at the end of treatment (T1). Mean treatment time was 17.7 months. Pretreatment and post-treatment cephalometric records of treated group were evaluated and compared with a control group consisted of 20 patients with untreated Class II malocclusion. Intergroup comparisons were performed using Student’s t-tests and chi-square test with Yates’ correction at a significance level of 5 per cent. Bionator appliance was effective in generating differential growth between the jaws. Cephalometric skeletal measurements ANB, WITS, Lafh, Co-A and dental L6-Mp, U1.Pp, IsIi, OB, OJ showed statistically significantly different from the control. Bionator induced more dentoalveolar changes than skeletal during treatment in prepubertal stage.

Published: October 2016

To evaluate the equilibrium and flexibility of elderly people submitted to a training program involving physical therapy exercises. Six elderly people were selected, average age 69.66 years. Wells’s Bench and the Functional Reach Test (FRT) plus Timed Up and Go Test (TUG) were employed respectively to assess muscle flexibility and balance analysis. Tests were performed before and after the exercise program which consisted of thirty-five 50 min physical therapy group sessions, twice a week, with stretching exercises, gait training, active exercises, postural correction exercises and breathing exercises. Statistical analysis was done with Sigma-Stat® 3.5. Assessments occurred before and after sessions, and the final test was undertaken after 35 sessions. There was a statistically significant increase in the flexibility of the posterior muscle chain. In the TUG test, the group achieved a shorter time after treatment, with statistical significance between tests. There was a statistically significant increase in the average FRT after the sessions. Current study showed better results in the execution of tests evaluated after the program of physiotherapy activities, contributing towards the improvement of muscle flexibility and balance of elderly people.

This study assessed the main determinants of sexual and reproductive health of Brazilian youth. It was approved by the Ethics Committee of the Medicine Faculty of the University of Brasília, and it received support from Paho and Brazilian Ministry of Health. 1.208 youngsters (18 to 29 years old) in 15 states and Federal District were interviewed at their residences, during the second semester of 2011. Margin of error, adjusted regional and nationally, was 2.8% (CI: 95%), regarding the assessed sample. A KAP scale (knowledge, attitudes, and practices) with 17 questions (-17 to +17 points) was generated. A questionnaire was pre-tested for consistency and validity analysis was performed. KAP scale was used as dependent variable in adjusted linear regression models. Mean KAP score was 5.65 points. Gaps in KAP were: 70% of the youth do not know when the fertility period of a woman is. 42% of youth do not recognize condoms as a method to prevent unwanted pregnancy and STDs. The main factors associated to explaining variances in KAP are gender, education, religion, access to health services, having had sexual intercourse in the last 12 months, and having friends as the main personal reference (p < 0.05). Youngsters with higher education, women, non-Protestant, who claim to know where to find health services have better KAP level of reproductive health. Studies are necessary to support public policies that increase the KAP levels in sexual and reproductive health of the most vulnerable groups, such as the segment comprising low education, men and Protestants.
Water-in-Oil–Only Adjuvants Selectively Promote T Follicular Helper Cell Polarization through a Type I IFN and IL-6–Dependent Pathway

Published: October 2016

T follicular helper (Tfh) cells are a subset of CD4+ T lymphocytes that promote the development of humoral immunity. Although the triggers required for the differentiation of the other major Th subsets are well defined, those responsible for Tfh cell responses are still poorly understood. We determined that mice immunized with peptide or protein Ags emulsified in IFA or related water-in-oil adjuvants develop a highly polarized response in which the majority of the Ag-specific CD4+ T cells are germinal center–homing CXCR5+Bcl6+ Tfh cells. Despite the absence of exogenous microbial pathogen-associated molecular patterns, the Tfh cell responses observed were dependent, in part, on MyD88. Importantly, in addition to IL-6, T cell–intrinsic type I IFN signaling is required for optimal Tfh cell polarization. These findings suggest that water-in-oil adjuvants promote Tfh cell–dominated responses by triggering endogenous alarm signals that, in turn, induce type I IFN–dependent differentiation pathway functioning in T cells.

Published: October 2016

Abstract Background: Hyperhemolytic Syndrome or Hyperhemolytic Transfusion Reaction (HHTR), a life-threatening subset of Delayed Hemolytic Transfusion Reaction (DHTR) is characterized by destruction of both transfused and autologous erythrocytes evidenced by a fall in post transfusion hemoglobin below the pre-transfusion level.Case report: We describe a case of DHTR due to anti-P1 alloimmunization manifesting with hyperhemolysis in a 30-year-old Greek Pomak woman with thalassemia intermedia (HbO-Arab/β-thalassemia), during the11th week of her first gestation. She was successfully managed with avoidance of further transfusions and administration of IVIG and corticosteroids.Conclusion: A high index of suspicion for HHTR is of vital importance among clinicians especially since optimal methods for its prevention and treatment remain yet to be defined. Early recognition of HHTR leading to prompt cessation of additional transfusions and initiation of immunosuppressive treatment can be life-saving, especially in clinical settings where limited therapeutic options are available, such as in pregnancy.
Panpsychism, pan-consciousness and the non-human turn: Rethinking being as conscious matter
Authors: Du Toit Cornel
Published: October 2016

It is not surprising that in a time of intensified ecological awareness a new appreciation of nature and the inanimate world arises. Two examples are panpsychism (the extension of consciousness to the cosmos) and deep incarnation (the idea that God was not only incarnated in human form but also in the non-human world). Consciousness studies flourish and are related to nature, the animal world and inorganic nature. A metaphysics of consciousness emerges, of which panpsychism is a good example. Panpsychism or panconsciousness or speculative realism endows all matter with a form of consciousness, energy and experience. The consciousness question is increasingly linked to the quantum world, which offers some option in bridging mind and reality, consciousness and matter. In this regard Kauffman’s notion of ‘triad’ is referred to as well as the implied idea of cosmic mind. This is related to the notion of ‘deep incarnation’ as introduced by Gregersen. Some analogical links are made between panpsychism and deep incarnation.
Hoist by our own petard: Backing slowly out of religion and development advocacy
Authors: Olivier Jill
Published: October 2016

There has been a massive advocacy movement over the last 15 years that has sought to advance the case of religion into view of decision-makers in the international development sector. This advocacy effort has been dispersed and not centrally organised, and is made up of the efforts of multiple development actors, religious institutions, researchers and others. This article shows how this advocacy approach has been highly successful in increasing acceptance of the fact that religion is relevant to development, and religious communities and institutions make contributions to the development effort – and this acceptance can now be seen at the highest levels. However, the article highlights several challenges that have come with this advocacy approach. It therefore supports urgent reflection on the direction of this advocacy going forward and suggests that major and uncomfortable adaptations might now be required.
Thomas F. Torrance: Theology and mission in practice
Authors: Seed Caroline G, , Lioy Daniel , Fick Rikus
Published: October 2016

This article proposes that scholarship needs to take into account the intensely missional and practical nature of T.F. Torrance’s life and work. Using primary sources, it isolates mission to the Qiang in China as the area in which personal mission practice and theology coincide. It shows that Torrance’s theology of divine-human communion is rooted in the missio Dei, expressed in the nature of the perichoretic interrelations of the ontological Trinity and the mission of the economic Trinity in the world through the covenant history of Israel. This concept is illustrated practically in the mission history of the Qiang. A holistic concept of mission and theology is therefore at the heart of both Torrance’s biography and theology.

This article investigates a statement by Dr Koot Vorster, at that stage a leading figure and church politician in the Dutch Reformed Church (DRC), in which he mentions that the proposed church order for the Dutch Reformed Church of 1962 was in essence the Order of Dordtrecht of 1619, adapted to suit the situation of the church in the 1960s. The Dutch Reformed Church’s affinity with the Church Order of Dordt over the years is highlighted and the content of the order of 1962 is studied for the influence of, and similarities with the Order of Dordt.
Role of demographic and job-related variables in determining work-related quality of life of hospital employees
Authors: Shukla K , Shahane S , D’Souza W
Published: October 2016

Background:

Considering a huge working population in health sector faced with stressful work life, limited autonomy in work and declining work contentment calls for an overemphasis on evaluating and monitoring their satisfaction associated with work-related quality of life (WRQoL). This study evaluates WRQoL of hospital employees and validates the bilingual (English and Marathi) version of WRQoL scale.

Methods:

The study was conducted during March–April’2014 on employees of a corporate hospital of Pune, India after ethical approval and informed consent from employees. The bilingual WRQoL scale has been tested for reliability and validity, and WRQoL scores have been reported.

Results:

A total of 132 hospital employees (mean age 31 [±8] years, 55% males) who participated in the study reported overall moderate WRQoL scores. The scale showed high internal consistency (Cronbach's alpha = 0.82, P < 0.0001) and moderate to high validity. WRQoL did not significantly vary across marital status, family size, and gender. “Stress at work” score of WRQoL increased with age of employees. Higher work experience, employment at higher positions and those working in clinical and diagnostic departments reported a higher WRQoL.

Conclusion:

WRQoL scale is a reliable and valid instrument. Better WRQoL in employees placed in higher organizational positions indicates a need for focused measures to enhance WRQoL of employees in lower hierarchical levels, especially in control at work and home life interface domains. WRQoL needs regular monitoring for employees in lower positions and aging employees.
On Gibbs Measures and Spectra of Ruelle Transfer Operators

Published: October 2016

We prove a comprehensive version of the Ruelle–Perron–Frobenius Theorem with explicit estimates of the spectral radius of the Ruelle transfer operator and various other quantities related to spectral properties of this operator. The novelty here is that the Hölder constant of the function generating the operator appears only polynomially, not exponentially as in previously known estimates.

Published: October 2016

Acute liver failure is an atypical manifestation of dengue with a high mortality. We performed a retrospective cohort study at the Hospital for Tropical Diseases, Bangkok, Thailand. In total, 1,926 patients with serologically confirmed dengue were enrolled in the study from 2011 to 2015. Of these, six patients presented with acute liver failure, four died, and two survived. The incidence of dengue-associated acute liver failure was 0.31%. Dengue-associated acute liver failure was most common among young adults (median age, 29 years). The median duration from onset of fever to development of acute liver failure was 7.5 days. Patients with the severe stage of dengue had a higher risk of developing acute liver failure (P < 0.001). The baseline risk factors associated with the development of acute liver failure were an age of ≤ 40 years (odds ratio [OR] = 1.5, 95% confidence interval [CI] = 1.1–2.0, P < 0.05), a > 10% ratio of atypical lymphocytes (OR = 2.3, 95% CI = 1.8–3.0, P < 0.001), and a platelet count of < 50,000 mm3 (OR = 2.8, 95% CI = 2.2–3.6, P < 0.001). The incidence of acute liver failure in patients with dengue was quite low, but its impact on morbidity, mortality, and poor clinical outcomes was significant. In summary, this study indicates that various baseline risk factors are associated with acute liver failure in patients with dengue.

O presente estudo foi realizado com o objetivo de avaliar a degradação térmica da madeira e a liberação de gases condensáveis e não condensáveis em sua carbonização. Utilizou-se madeira de Eucalyptus spp. com aproximadamente 7 anos de idade, proveniente de um teste clonal de uma empresa florestal, localizado em Divinésia, MG. Foram realizadas a análise termogravimétrica da madeira (TG/DTG) e carbonizações em mufla a fim de determinar o comportamento térmico da madeira e o fator de emissão dos gases não condensáveis e condensáveis (CO, CO2, CH4, H2, e licor pirolenhoso). Instalou-se o experimento a fim de se descrever as médias das emissões de gases não condensáveis e condensáveis. A degradação térmica da madeira seguiu comportamento inverso às emissões de dióxido de carbono, monóxido de carbono, metano, hidrogênio e de líquido condensável. Pode-se concluir que a utilização de faixas teóricas de degradação da madeira na condução da carbonização, mesclando as curvas TG/DTG com a evolução de emissão dos gases da carbonização até temperaturas finais do processo pode contribuir para a redução da emissão de metano (principal gás de efeito estufa), por promover o controle da temperatura e aumentar o rendimento gravimétrico em carvão vegetal.

Em toda região da Floresta Ombrófila Mista, parte do Bioma Mata Atlântica, o corte seletivo e pastoreio são atividades muito comuns. Com o objetivo de relacionar a composição e estrutura com o histórico de uso, foram avaliados os indivíduos arbóreos adultos e juvenis de 12 fragmentos em Santa Catarina. Os fragmentos com menor impacto antrópico apresentaram, para o estrato adulto, maior riqueza e amplitude diamétrica, e menor densidade e frequência de múltiplos fustes, apesar da área basal não diferir entre os fragmentos. Quanto ao estrato juvenil, os fragmentos com maior impacto apresentaram maior riqueza e menor densidade. Os resultados demonstram que o impacto antrópico sobre a comunidade arbórea foi de tal magnitude, que, mesmo passadas algumas décadas, diferenças florísticas e estruturais permanecem evidentes, com tendência a se manterem por longo período.

O objetivo deste estudo foi comparar o desempenho de dois modelos não-lineares e o sistema de equações simultâneas de Clutter na progrnose do volume de madeira em povoamentos clonais e superestoocados de Eucalyptus spp no Espírito Santo, Brasil. Para fins de avaliação da qualidade dos ajustes e comparação dos modelos, foi utilizado o Erro Padrão da Média Percentual, os Critérios de Informação de Akaike e Bayesiano, complementados pela análise gráfica dos resíduos padronizados. A inclusão das covariáveis, sítio e área basal, nos sistemas não-lineares de projeção em volume garantiram uma melhoria expressiva na acurácia das estimativas para a função logística com erros reduzidos em até quatro vezes. Verificou-se ainda que a função logística com inclusão de variáveis foi altamente superior a sua forma original de ajuste e mais coerente quando comparada ao sistema de equações simultâneas de Clutter. Os resultados permitiram inferir ainda sobre a superioridade do sistema não-linear de modelagem indicando valores de incremento médio anual máximos próximos a 5 anos, o que o torna condizente com a realidade das plantações florestais de eucalipto para produção de biomassa no Brasil.

Seed dormancy is a phenomenon observed in several tropical species. This condition causes low and non-uniform germination. The present study was designed to identify an efficient method of breaking seed dormancy in Stryphnodendron pulcherrimum. Seeds of four mother plants were subjected to the following treatments: immersion in sulfuric acid for 2, 4, 6, 8, 10 and 12 min and scarification on 150-grit sandpaper. Seeds were sown on substrate containing sand and sawdust (1:1). It was evaluate the days to onset seedlings emergence, seedlings emergence (SE), emergence speed index (ESI), germination (G), hard seeds (HS), dead seeds (DS), dormant seeds (DMS), abnormal seedlings (AS) and dry mass of aerial part (DMAP) and roots (DMR). The experimental design was completely randomized with four replications of 25 seeds for each treatment. Data were subjected to analysis of variance and means compared by Tukey's test (p < 0.05). Significant differences among treatments were observed for ESI, SE, G, HS, DMAP and DMR. Highest HS was observed in control treatment (85%). Highest G was observed in seeds scarified with sulfuric acid for 10 min (82%) and 12 min (74%). These treatments also showed highest ESI, DMAP and DMR, indicating that these scarification treatments were the most efficient in overcoming dormancy.
La iglesia de Sainte-Bernadette en Nevers. ¿Conclusión expresiva o principio oblicuo?
Authors: Fullaondo Buigas de Dalmau Diego
Published: October 2016

Claude Parent y Paul Virilo concibieron La Fonction Oblique entre 1963 y 1966. Su encargo edifi catorio más significativo fue la Iglesia de Sainte Bernadette en Nevers que se presentó como la materialización de la teoría. Sin embargo, más que un proyecto sobre la oblicuidad, Nevers es un ejercicio de traducción de una antigua obsesión de Virilio, los bunkers alemanes de la Guerra Mundial, y una conclusión plástica de Parent a su experimentación previa entorno al informalismo arquitectónico. Esta falta de concordancia ha provocado un cierto desconcierto tanto con respecto a La Fonctión Oblique como al proyecto de Nevers.

Abstract. There exists observational evidence that gaseous elemental mercury (GEM) can be readily removed from the atmosphere via chemical oxidation followed by deposition in the polar and sub-polar regions, free troposphere, lower stratosphere, and marine boundary layer under specific environmental conditions. Here we report GEM depletions in a temperate mixed forest at Mt. Changbai, Northeast China. The strong depletions occurred predominantly at night during the leaf-growing season and in the absence of gaseous oxidized mercury (GOM) enrichment (GOM  <  3 pg m−3). Vertical gradients of decreasing GEM concentrations from layers above to under forest canopy suggest in situ loss of GEM to forest canopy at Mt. Changbai. Foliar GEM flux measurements showed that the foliage of two predominant tree species is a net sink of GEM at night, with a mean flux of −1.8 ± 0.3 ng m2 h−1 over Fraxinus mandshurica (deciduous tree species) and −0.1 ± 0.2 ng m2 h−1 over Pinus Koraiensis (evergreen tree species). Daily integrated GEM δ202Hg, Δ199Hg, and Δ200Hg at Mt. Changbai during 8–18 July 2013 ranged from −0.34 to 0.91 ‰, from −0.11 to −0.04 ‰ and from −0.06 to 0.01 ‰, respectively. A large positive shift in GEM δ202Hg occurred during the strong GEM depletion events, whereas Δ199Hg and Δ200Hg remained essentially unchanged. The observational findings and box model results show that uptake of GEM by forest canopy plays a predominant role in the GEM depletion at Mt. Changbai forest. Such depletion events of GEM are likely to be a widespread phenomenon, suggesting that the forest ecosystem represents one of the largest sinks ( ∼ 1930 Mg) of atmospheric Hg on a global scale.
Formation of secondary organic aerosols from the ozonolysis of dihydrofurans

Abstract. In this work we report the study of the ozonolysis of 2,5-dihydrofuran and 2,3-dihydrofuran and the reaction conditions leading to the formation of secondary organic aerosols. The reactions have been carried out in a Teflon chamber filled with synthetic air mixtures at atmospheric pressure and room temperature. The ozonolysis only produced particles in the presence of SO2. Water vapour has no effect on the production of secondary organic aerosol in the case of 2,5-dihydrofuran while it reduces the particle number and particle mass concentrations from the 2,3-dihydrofuran ozonolysis. The water and SO2 rate constants ratio for the 2,3-dihydrofuran Criegee intermediate was derived from the SOA yields in experiments with different relative humidity values, kH2O/kSO2 = (9.8 ± 3.7) ×10−5. The experimental results show that SO3 is not an intermediate in the formation or growth of new particles in contrast to the data reported for other Criegee intermediates/SO2 reactions. For the studied reactions, SO2 behaves as a catalyst in the production of condensable products. Computational calculations show that the stabilised Criegee intermediates from the ozonolysis reaction of both 2,5-dihydrofuran and 2,3-dihydrofuran may react with SO2 resulting in the regeneration of SO2 and the formation of organic acids.
MAX-DOAS retrieval of aerosol extinction properties in Madrid, Spain
Authors: Wang Shanshan , Cuevas Carlos A. , Frieß Udo , Saiz-Lopez Alfonso
Published: October 2016

Abstract. Multi-axis differential optical absorption spectroscopy (MAX-DOAS) measurements were performed in the urban environment of Madrid, Spain, from March to September 2015. The O4 absorption in the ultraviolet (UV) spectral region was used to retrieve the aerosol extinction profile using an inversion algorithm. The results show a good agreement between the hourly retrieved aerosol optical depth (AOD) and the correlative Aerosol Robotic Network (AERONET) product, with a correlation coefficient of R =  0.87. Higher AODs are found in the summer season due to the more frequent occurrence of Saharan dust intrusions. The surface aerosol extinction coefficient as retrieved by the MAX-DOAS measurements was also compared to in situ PM2.5 concentrations. The level of agreement between both measurements indicates that the MAX-DOAS retrieval has the ability to characterize the extinction of aerosol particles near the surface. The retrieval algorithm was also used to study a case of severe dust intrusion on 12 May 2015. The capability of the MAX-DOAS retrieval to recognize the dust event including an elevated particle layer is investigated along with air mass back-trajectory analysis.
The impacts of data constraints on the predictive performance of a
general process-based crop model (PeakN-crop v1.0)

Abstract. Improving international food security under a changing climate and increasing human population will be greatly aided by improving our ability to modify, understand and predict crop growth. What we predominantly have at our disposal are either process based models of crop physiology or statistical analyses of yield datasets, both of which suffer from various sources of error. In the current paper we present a generic process based crop model which we parametrise using a Bayesian model ﬁtting algorithm to three different sources of data – space based vegetation indices, eddy covariance productivity measurements and regional crop yields. We show that the model parametrised without data, based on prior knowledge of the parameters can largely capture the observed behaviour but the data constrained model greatly improves both the model ﬁt and reduces prediction uncertainty. We investigate the extent to which each dataset contributes to the model performance and show that while all data improves on the prior model ﬁt, the satellite based data and crop yield estimates are particularly important for reducing model error and uncertainty. Despite these improvements, we conclude that there are still signiﬁcant knowledge10 gaps, in terms of available data for model parametrisation, but our study can help indicate the necessary data collection steps for improvement in our predictions of crop yields and crop responses to environmental changes.
DEVELOPMENT OF HIGH PERFORMANCE RUBBER COMPOSITES FROM ALKOXIDE-BASED SILICA AND SOLUTION STYRENE–BUTADIENE RUBBER

The solution SBR and silica-based composites are prepared by hydrolysis of tetraethylorthosilicate in the presence of an organic solution of SBR and n-butylamine as catalyst. Further addition of bis[3-(triethoxysilyl)propyl]tetrasulfide, a silane coupling agent, improves the performance and properties of the composites. All the results are compared with commercial precipitated silica at similar loading conditions. The generated silica particles from this alkoxide route resulted in lower Mooney viscosity of the compound and showed less filler flocculation compared with standard commercial precipitated silica in reference compounds. A detailed dynamic mechanical study also indicated that alkoxide silica in model tire compounds could offer a lower rolling resistance and a higher wet skid resistance compared to the reference. Other properties such as heat build-up, rebound resilience, and hysteresis loss were found to be very promising for alkoxide silica composites, too. The silica particles (aggregated) developed by the alkoxide method were relatively large (∼150–200 nm) compared with the primary particles of precipitated commercial silica. The synthesis of sol–gel silica particles in presence of the polymer allowed for the trapping of some polymer molecules inside the filler aggregates and therefore offers exceptional mechanical reinforcement of the rubber.
Educational Model for Self-Healing: Eliminating a Chronic Migraine with Electromyography, Autogenic Training, Posture, and Mindfulness
Authors: Peper Erik , Miceli Brandy , Harvey Richard
Published: October 2016

An educational approach is often different from a clinical treatment approach to promote healing. Using an educational approach, 80% of university students who are enrolled in a holistic health course report that both acute and chronic disorders can be ameliorated or eliminated when they engage in daily self-practice of autogenic training, biofeedback self-regulation practices, and/or somatic posture awareness. This process of reducing health problems is illustrated by a case report of a 20-year-old female student who experienced three migraines per week for the past 6 years. After practicing self-regulation and body awareness techniques such as autogenic training, surface electromyography–assisted muscle awareness, diaphragmatic breathing, and postural changes, the frequency of her headaches decreased to zero. Being mindful without judgment and continuously interrupting her “chained behavior” patterns were major components for improving health. At 20-month follow-up, the student continued to be headache free. This type of integrated self-healing educational approach is recommended for students, patients, and anyone who wants to create lasting health changes.

Objetivou-se analisar a tendência temporal das internações por hipertensão arterial e diabetes entre idosos residentes no Estado do Paraná, no período de 2001 a 2013. Estudo ecológico, de séries temporais com dados secundários do Sistema de Informação do Sistema Único de Saúde, referentes às taxas de hospitalizações por hipertensão e diabetes em idosos, coletados em abril de 2014 e analisados segundo estatística descritiva e regressão polinomial. Foram registradas 59.481 internações por diabetes e 39.637 por hipertensão. A tendência de internação por diabetes foi crescente para homens (r2=0,85; p<0,001), nas faixas etárias de 60 a 69 e maiores de 80 anos (r2=0,66; p<0,042 e r2=0,69; p<0,002 respectivamente). Para hipertensão, a tendência foi decrescente entre mulheres e homens (r2=0,91; p<0,001 e r2=0,82; p<0,001 respectivamente). Os resultados mostraram-se similares a outros estudos, reforçando a necessidade do uso de sistemas de informação como fonte no planejamento das ações em saúde voltadas a população idosa.
