Authors: Martínez Tornero Carlos A.
Published: September 2016

En este trabajo pretendemos reconstruir el estado en el que se encontraba la Provincia jesuítica de Aragón entre dos fechas de gran importancia, como fueron el momento de la expulsión (1767) y el año siguiente al de su extinción canónica (1774). Asimismo, aportaremos información sobre cuestiones como la de los jesuitas secularizados, los que quedaron depositados en España, los novicios que comenzaron a cobrar la pensión vitalicia, etc., para obtener, con todo ello, un retrato aproximado sobre la que fuera Provincia jesuita de Aragón en 1774.
Characteristics of citations in postgraduate theses of sociology and economics: a comparative study
Authors: Gunasekera Chamani
Published: September 2016

This study analyses the sources cited in 32 post graduate (Master and PhD) theses in sociology and economics at University of Peradeniya submitted between 1996 and 2014. The objectives of this citation analysis were to find out the types of cited documents, the chronological distribution and authorship pattern of cited documents in the fields of sociology and economics, and to compare them. Citations were chosen from the title pages and the lists of references of each dissertation were examined. Data included the year of submission of thesis, source of citations, age of materials cited and types of authorship. Citations to journals were further analyzed to examine their authorship pattern, research collaboration, geographical location and check the applicability to Bradford Law of scattering. Results revealed that both sociology and economics authors cited mostly books, which proved previous studies that found social science disciplines cited books mostly than science disciplines. Citations in both sociology and economics were almost entirely of English language sources. Economics scholars cited latest materials than sociology scholars did. The results indicated that sociology literature is scattered among various subjects than economics. There is no significant difference between the citation behavior of sociology and economics scholars of University of Peradeniya except some differences in chronological distribution and research collaboration. Understanding the citation behavior of sociology and economics scholars will help librarians to formulate pragmatic policies and making decisions on collection development.
Imaging in spinal posterior epidural space lesions: A pictorial essay
Authors: Gala Foram B , Aswani Yashant
Published: September 2016

Spinal epidural space is a real anatomic space located outside the dura mater and within the spinal canal extending from foramen magnum to sacrum. Important contents of this space are epidural fat, spinal nerves, epidural veins and arteries. Due to close proximity of posterior epidural space to spinal cord and spinal nerves, the lesions present with symptoms of radiculopathy and/or myelopathy. In this pictorial essay, detailed anatomy of the posterior epidural space, pathologies affecting it along with imaging pearls to accurately diagnose them are discussed. Various pathologies affecting the posterior epidural space either arising from the space itself or occurring secondary to vertebral/intervertebral disc pathologies. Primary spinal bone tumors affecting the posterior epidural space have been excluded. The etiological spectrum affecting the posterior epidural space ranges from degenerative, infective, neoplastic - benign or malignant to miscellaneous pathologies. MRI is the modality of choice in evaluation of these lesions with CT scan mainly helpful in detecting calcification. Due to its excellent soft tissue contrast, Magnetic Resonance Imaging is extremely useful in assessing the pathologies of posterior epidural space, to know their entire extent, characterize them and along with clinical history and laboratory data, arrive at a specific diagnosis and guide the referring clinician. It is important to diagnose these lesions early so as to prevent permanent neurological complication.

Persistent ductus venosus as a cause of cholestatic jaundice is very rare. Treatment varies, but is usually reserved for infants in whom complications develop. We report a 5-week-old female infant with cholestatic jaundice caused by a patent ductus venosus and subsequent successful treatment via a transcatheter occlusion using a vascular plug device.
Transmural coil embolization—alternative technique for management of arterial perforation during subintimal angioplasty
Authors: Damodharan Karthikeyan , Bolia Amman
Published: September 2016

Subintimal angioplasty of lower limb arterial occlusion carries a relatively higher risk of vessel perforation compared to transluminal angioplasty. Vessel perforation is a potentially life threatening complication which requires prompt recognition and management. They are usually managed by endovascular techniques such as low-pressure balloon tamponade, covered stents, and coil embolization of the ruptured artery. We describe a technique of treating vessel perforation following balloon angioplasty. Patient developed a large perforation of the proximal superficial femoral artery (SFA) after balloon inflation during subintimal angioplasty of complete SFA occlusion. Following failure of balloon tamponade in sealing the perforation, we successfully treated it by deploying an embolization coil at the site of perforation through the vessel wall followed by balloon tamponade. Our technique could be a useful relatively inexpensive alternative treatment option in the management of vessel perforation compared to covered stents.
Sclerosing liposarcoma of epididymis: Role of chemical shift magnetic resonance imaging
Authors: Ramanathan Subramaniyan , Raghu Vineetha , Kumar Devendra , Sempiege Venkata R P
Published: September 2016

Sclerosing liposarcoma of epididymis is a rare extratesticular scrotal tumor with variable prognosis. Ultrasonography is the initial imaging modality of choice for the evaluation of scrotal mass and helps to differentiate testicular and extratesticular masses, thereby narrowing down the differential diagnosis. Magnetic resonance imaging with its excellent soft tissue resolution can help in the further characterization of the nature of the tumor. In this case report, we highlight the role of chemical shift imaging in making a confident preoperative diagnosis of liposarcoma thereby guiding optimal and timely management.
CT manifestations of small bowel ischemia due to impaired venous drainage-with a correlation of pathologic findings
Authors: Chou Chung Kuao
Published: September 2016

Acute abdominal pain may result from a wide variety of medical and surgical diseases. One of these diseases is small bowel ischemia, which may result in a catastrophic outcome if not recognized and treated promptly. Computed tomography (CT) by its faster image acquisition, thinner collimation, high resolution, and multiplanar reformatted images has become the most important imaging modality in evaluating the acute abdominal conditions. In this article, the author presents a description of the histology of the small bowel, pathophysiology of small bowel change, and a correlation of the pathologic and CT findings of the small bowel injuries due to impaired venous drainage. A convincing correlation of the microscopic mucosal condition with the enhancement pattern of the thickened small bowel wall on CT is useful in definitely describing the mucosal viability.
Acquired Hemophilia a may be Associated with Ticagrelor Therapy in a 52-Year-Old Man after a Recent Percutaneous Transluminal Coronary Angioplasty
Authors: Pasquino Paola , Canaparo Roberto , Capello Tiziana , Deorsola Barbara , Perazzolo Laura , Marengo Claudio , Serpe Loredana
Published: September 2016

We present a case report of a 52-year-old man who was hospitalized for right leg pain due to a relevant hemorrhagic effusion. He was on dual antiplatelet therapy (DAPT): acetylsalicylic acid and ticagrelor, a reversible P2Y12 receptor antagonist. Signs, symptoms, and laboratory blood tests led to the diagnosis of acquired hemophilia A (AHA). Ticagrelor therapy-associated AHA was hypothesized due to the fact that, before adding this drug, all laboratory and clinical examinations were repeatedly normal. Prednisone and cyclophosphamide treatment was started without DAPT interruption due to the high risk of stent thrombosis. After 10 days, prolonged activated partial thromboplastin time dropped from 107 to 49 seconds, the patient's factor VIII (FVIII) levels gradually normalized over the following few weeks, and FVIII inhibitor titer was negative. Recently, some reports have established a link between the development of AHA and treatment with clopidogrel, an irreversible P2Y12 receptor antagonist. However, to the best of our knowledge, this is the first time that a link between AHA and ticagrelor has been reported.
Regular colored graphs of positive degree

Regular colored graphs are dual representations of pure colored

D

-dimensional complexes. These graphs can be classified with respect to a positive integer, their degree, much like maps are characterized by the genus. We analyze the structure of regular colored graphs of fixed degree and perform their exact and asymptotic enumeration. In particular we show that the generating function of the family of graphs of fixed degree is an algebraic series with a positive radius of convergence, independent of the degree. We describe the singular behavior of this series near its dominant singularity, and use the results to establish the double scaling limit of colored tensor models: interestingly the behavior is qualitatively very different for

Abstract. The major volcanic eruption of Mount Pinatubo in 1991 has been shown to have significant effects on stratospheric chemistry and ozone depletion even at mid-latitudes. Since then, only "moderate" but recurrent volcanic eruptions have modulated the stratospheric aerosol loading such as the eruption of the mid-latitude Sarychev volcano which injected 0.9 Tg of sulfur dioxide (about 20 times less than Pinatubo) in June 2009. In this study, we investigate the chemical impacts of the enhanced liquid sulfate aerosol loading resulting from this moderate eruption using data from a balloon campaign conducted in northern Sweden (Kiruna-Esrange, 67.5° N, 21.0° E) in August-September 2009. Balloon-borne observations of NO2, HNO3 and BrO from infrared and UV-visible spectrometers are compared with the outputs of a three-dimensional (3-D) Chemistry-Transport Model (CTM). It is shown that differences between observations and model outputs are not due to transport calculation issues but rather reflect the chemical impact of the volcanic plume below 19 km in altitude. Good measurement-model agreement is obtained when the CTM is driven by volcanic aerosol loadings derived from in situ or space-borne data. As a result of enhanced N2O5 hydrolysis in the Sarychev volcanic aerosol conditions, the model calculates reductions of ~ 45 % and increases of ~ 11 % in NO2 and HNO3 amounts respectively over the summer 2009 period. The decrease in NOx abundances is limited due to the expected saturation effect for high aerosol loadings. The links between the various chemical catalytic cycles involving chlorine, bromine, nitrogen and HOx compounds in the lower stratosphere are discussed. The increased BrO amounts (~ 22 %) compare rather well with the balloon-borne observations when volcanic aerosol levels are accounted for in the CTM and appear to be mainly controlled by the coupling with nitrogen chemistry rather than by enhanced BrONO2 hydrolysis. Simulated effects of the Sarychev eruption on chlorine activation and partitioning are very limited in the high temperature conditions in the stratosphere at the period considered, inhibiting the effect of ClONO2 hydrolysis. As a consequence, the simulated ozone loss due to the Sarychev aerosols is low with a reduction of 1.1 % of the ozone budget at 16.5 km. Some comparisons with the reported Pinatubo chemical impacts are also provided and overall the Sarychev aerosols have led to less chemical effects than the Pinatubo event.
Inter-comparison of NIOSH and IMPROVE protocols for OC and EC determination:
implications for inter-protocol data conversion
Authors: Wu Cheng , Huang X. H. Hilda , Ng Wai Man , Griffith Stephen M. , Yu Jian Zhen
Published: September 2016

Abstract. Organic carbon (OC) and elemental carbon (EC) are operationally defined by analytical methods. As a result, OC and EC measurements are protocol dependent, leading to uncertainties in their quantification. In this study, more than 1300 Hong Kong samples were analyzed using both National Institute for Occupational Safety and Health (NIOSH) thermal optical transmittance (TOT) and Interagency Monitoring of Protected Visual Environment (IMPROVE) thermal optical reflectance (TOR) protocols to explore the cause of EC disagreement between the two protocols. EC discrepancy mainly (83 %) arises from a difference in peak inert mode temperature, which determines the allocation of OC4NSH, while the rest (17 %) is attributed to a difference in the optical method (transmittance vs. reflectance) applied for the charring correction. Evidence shows that the magnitude of the EC discrepancy is positively correlated with the intensity of the biomass burning signal, whereby biomass burning increases the fraction of OC4NSH and widens the disagreement in the inter-protocol EC determination. It is also found that the EC discrepancy is positively correlated with the abundance of metal oxide in the samples. Two approaches (M1 and M2) that translate NIOSH TOT OC and EC data into IMPROVE TOR OC and EC data are proposed. M1 uses direct relationship between ECNSH_TOT and ECIMP_TOR for reconstruction: M1 : ECIMP_TOR = a × ECNSH_TOT + b;  while M2 deconstructs ECIMP_TOR into several terms based on analysis principles and applies regression only on the unknown terms: M2  : ECIMP_TOR =  AECNSH + OC4NSH − (a × PCNSH_TOR + b),  where AECNSH, apparent EC by the NIOSH protocol, is the carbon that evolves in the He–O2 analysis stage, OC4NSH is the carbon that evolves at the fourth temperature step of the pure helium analysis stage of NIOSH, and PCNSH_TOR is the pyrolyzed carbon as determined by the NIOSH protocol. The implementation of M1 to all urban site data (without considering seasonal specificity) yields the following equation: M1(urban data) : ECIMP_TOR = 2.20 × ECNSH_TOT − 0.05. While both M1 and M2 are acceptable, M2 with site-specific parameters provides the best reconstruction performance. Secondary OC (SOC) estimation using OC and EC by the two protocols is compared. An analysis of the usability of reconstructed ECIMP_TOR and OCIMP_TOR suggests that the reconstructed values are not suitable for SOC estimation due to the poor reconstruction of the OC / EC ratio.
MATRIX-VBS: implementing an evolving organic aerosol volatility in an aerosol microphysics model
Authors: Gao Chloe Y. , Tsigaridis Kostas , Bauer Susanne E.
Published: September 2016

Abstract. We have implemented an existing aerosol microphysics scheme into a box model framework and extended it to represent gas-particle partitioning and chemical ageing of semi-volatile organic aerosols. We then applied this new research tool to investigate the effects of semi-volatile organic species on the growth, composition and mixing state of aerosol particles in case studies representing several different environments. The volatility-basis set (VBS) framework is implemented into the aerosol microphysical scheme MATRIX (Multiconfiguration Aerosol TRacker of mIXing state), which resolves mass and number aerosol concentrations and in multiple mixing-state classes. The new scheme, MATRIX-VBS, has the potential to significantly advance the representation of organic aerosols in Earth system models by improving upon the conventional representation as non-volatile particulate organic matter, often with also an assumed fixed size distribution. We present results from idealized cases representing Beijing, Mexico City, a Finnish and a Southeast U.S. forest, and investigate the evolution of mass concentrations and volatility distributions for organic species across the gas and particle phases, as well as assessing their mixing state among aerosol populations. Emitted semi-volatile primary organic aerosols evaporate almost completely in the high volatile range, while they remain in the particle phase in the low volatility range. Their volatility distribution depends on the applied emission factors, oxidation by OH radicals, and temperature. We also compare against parallel simulations with the original scheme, which represented only the particulate and non-volatile component of the organic aerosol, examining how differently the condensed phase organic matter is distributed across the mixing states in the model. The results demonstrate the importance of representing organic aerosol as a semi-volatile aerosol, and explicitly calculating the partitioning of organic species between the gas and particulate phases.

Abstract. We present an overview of state-of-the-art chemistry-climate and -transport models that are used within the Chemistry-Climate Model Initiative (CCMI). CCMI aims to conduct a detailed evaluation of participating models using process-oriented diagnostics derived from observations in order to gain confidence in the models' projections of the stratospheric ozone layer, air quality, where applicable global climate change, and the interactions between them. Interpretation of these diagnostics requires detailed knowledge of the radiative, chemical, dynamical, and physical processes incorporated in the models. Also an understanding of the degree to which CCMI recommendations for simulations have been followed is necessary to understand model response to anthropogenic and natural forcing and also to explain inter-model differences. This becomes even more important given the ongoing development and the ever-growing complexity of these models. This paper also provides an overview of the available CCMI simulations with the aim to inform CCMI data users.

Abstract. We evaluate the capability of the global atmospheric transport model TM5 to simulate the boundary layer dynamics and associated variability of trace gases close to the surface, using radon (222Rn). Focusing on the European scale, we compare the boundary layer height (BLH) in the TM5 model with observations from the National Oceanic and Atmospheric Admnistration (NOAA) Integrated Global Radiosonde Archive (IGRA) and also with ceilometer and lidar (light detection and ranging) BLH retrievals at two stations. Furthermore, we compare TM5 simulations of 222Rn activity concentrations, using a novel, process-based 222Rn flux map over Europe (Karstens et al., 2015), with harmonised 222Rn measurements at 10 stations. The TM5 model reproduces relatively well the daytime BLH (within 10–20 % for most of the stations), except for coastal sites, for which differences are usually larger due to model representation errors. During night, however, TM5 overestimates the shallow nocturnal BLHs, especially for the very low observed BLHs (< 100 m) during summer. The 222Rn activity concentration simulations based on the new 222Rn flux map show significant improvements especially regarding the average seasonal variability, compared to simulations using constant 222Rn fluxes. Nevertheless, the (relative) differences between simulated and observed daytime minimum 222Rn activity concentrations are larger for several stations (on the order of 50 %) than the (relative) differences between simulated and observed BLH at noon. Although the nocturnal BLH is often higher in the model than observed, simulated 222Rn nighttime maxima are actually larger at several continental stations. This counterintuitive behaviour points to potential deficiencies of TM5 to correctly simulate the vertical gradients within the nocturnal boundary layer, limitations of the 222Rn flux map, or issues related to the definition of the nocturnal BLH. At several stations the simulated decrease of 222Rn activity concentrations in the morning is faster than observed. In addition, simulated vertical 222Rn activity concentration gradients at Cabauw decrease faster than observations during the morning transition period, and are in general lower than observed gradients during daytime. Although these effects may be partially due to the slow response time of the radon detectors, they clearly point to too fast vertical mixing in the TM5 boundary layer during daytime. Furthermore, the capability of the TM5 model to simulate the diurnal BLH cycle is limited by the current coarse temporal resolution (3 h/6 h) of the TM5 input meteorology.
Determinants of modelling choices for 1-D free-surface flow and
morphodynamics in hydrology and hydraulics: a review
Authors: Cheviron Bruno , Moussa Roger
Published: September 2016

Abstract. This review paper investigates the determinants of modelling choices, for numerous applications of 1-D free-surface flow and morphodynamic equations in hydrology and hydraulics, across multiple spatiotemporal scales. We aim to characterize each case study by its signature composed of model refinement (Navier–Stokes: NS; Reynolds-averaged Navier–Stokes: RANS; Saint-Venant: SV; or approximations to Saint-Venant: ASV), spatiotemporal scales and subscales (domain length: L from 1 cm to 1000 km; temporal scale: T from 1 s to 1 year; flow depth: H from 1 mm to 10 m; spatial step for modelling: δL; temporal step: δT), flow typology (Overland: O; High gradient: Hg; Bedforms: B; Fluvial: F), and dimensionless numbers (dimensionless time period T*, Reynolds number Re, Froude number Fr, slope S, inundation ratio Λz, Shields number θ). The determinants of modelling choices are therefore sought in the interplay between flow characteristics and cross-scale and scale-independent views. The influence of spatiotemporal scales on modelling choices is first quantified through the expected correlation between increasing scales and decreasing model refinements (though modelling objectives also show through the chosen spatial and temporal subscales). Then flow typology appears a secondary but important determinant in the choice of model refinement. This finding is confirmed by the discriminating values of several dimensionless numbers, which prove preferential associations between model refinements and flow typologies. This review is intended to help modellers in positioning their choices with respect to the most frequent practices, within a generic, normative procedure possibly enriched by the community for a larger, comprehensive and updated image of modelling strategies.
After some 350 years – zero declination again in Paris
Authors: Mandea Mioara , Le Mouël Jean-Louis
Published: September 2016

Abstract. The main part of the geomagnetic field – produced by a dynamo process in the Earth's outer core – changes its direction and strength in time, over timescales from months to centuries, even millennia. Its temporal variations, known as secular variation and secular acceleration, are crucial ingredients for understanding the physics of the deep Earth. Very long series of measurements therefore play an important role. Here, we provide an updated series of geomagnetic declination in Paris, shortly after a very special occasion: its value has reached zero after some 350 years of westerly values. Indeed, during October and November 2013, the declination at the Chambon la Forêt geomagnetic observatory changed from westerly to easterly values, the agonic line then passing through this place. We take this occasion to emphasize the importance of long series of continuous measurements.
An integrated methodology to develop a standard for landslide early warning
systems
Authors: Fathani Teuku Faisal , Karnawati Dwikorita , Wilopo Wahyu
Published: September 2016

Abstract. Landslides are one of the most widespread and commonly occurring natural hazards. In regions of high vulnerability, these complex hazards can cause significant negative social and economic impacts. Considering the worldwide susceptibility to landslides, it is necessary to establish a standard for early warning systems specific to landslide disaster risk reduction. This standard would provide guidance in conducting landslide detection, prediction, interpretation, and response. This paper proposes a new standard consisting of seven sub-systems for landslide early warning. These include risk assessment and mapping, dissemination and communication, establishment of the disaster preparedness and response team, development of an evacuation map, standardized operating procedures, installation of monitoring and warning services, and the building of local commitment to the operation and maintenance of the entire program. This paper details the global standard with an example of its application from Central Java, one of 20 landslide-prone provinces in Indonesia that have used this standard since 2012.

Published: September 2016

Abstract. The microstructure and density of ice layers in snowpacks is poorly quantified. Here we present a new field method for measuring the density of ice layers caused by melt or rain-on-snow events. The method was used on 87 ice layer samples taken from natural and artificial ice layers in the Canadian Arctic and mid-latitudes. Mean measured ice layer density was 909 ± 28 kg m−3 with a standard deviation of 23 kg m−3, significantly higher than values typically used in the literature.

The Effectiveness of Acceptance and Commitment Therapy (ACT) on Self-Efficacy, Perceived Stress and Resiliency in Type II Diabetes Patients
Authors: Khashouei Masoumeh Mohammadi , Ghorbani Maryam , Tabatabaei Fatemeh
Published: September 2016

INTRODUCTION: The prevalence of diabetes, especially type II diabetes, is increasing in the world. It seems that psycho-cognitive factors such as perceived-stress and resiliency can play an important role in diabetes care. The aim of the present study is examining the effect of Acceptance and Commitment Therapy (ACT) on self-efficacy, perceived stress and resiliency in type II diabetes patients.

METHODS: The method of this research was quasi-experimental (pre- test, post -test) with follow-up stages. The population includes women with type II diabetes that refer to Endocrine and Metabolism Research center, Isfahan university of Medical Sciences in 2014. Thirty two patients were selected by convenience sampling and they were randomly divided into two groups, namely experimental and control group (n1 =16, n2 = 16) and the follow-up stage was performed 3 months after the post test. Research tools consisted of questionnaires of self-efficacy (Sherer et al., 1982), perceived-stress (Cohen, Kamarck, & Mermelstein, 1983) and resiliency (Connor & Davidson, 2003). Term of ACT treatment was 8 sessions with one session every week in the experimental group and follow-up stage was performed three months after the post test.

RESULTS: Results showed that after the treatment, the scores of self-efficacy and perceived-stress was reduced significantly compared to the control group (p<0.05) in all stages, but in resiliency they did not show any significant differences with each other in post test stage. However, in follow-up stage, the scores were reduced significantly compared to the scores in the control group (p<0.05).

CONCLUSION: The results show that ACT can be useful for psycho-cognitive function in type II diabetes patients.
Notch-Expanded Murine Hematopoietic Stem and Progenitor Cells Mitigate Death from Lethal Radiation and Convey Immune Tolerance in Mismatched Recipients

Published: September 2016

The hematopoietic syndrome of acute radiation syndrome (h-ARS) is characterized by severe bone marrow aplasia, resulting in a significant risk for bleeding, infections, and death. To date, clinical management of h-ARS is limited to supportive care dictated by the level of radiation exposure, with a high incidence of mortality in those exposed to high radiation doses. The ideal therapeutic agent would be an immediately available, easily distributable single-agent therapy capable of rapid in vivo hematopoietic reconstitution until recovery of autologous hematopoiesis occurs. Using a murine model of h-ARS, we herein demonstrate that infusion of ex vivo expanded murine hematopoietic stem and progenitor cells (HSPCs) into major histocompatibility complex mismatched recipient mice exposed to a lethal dose of ionizing radiation (IR) led to rapid myeloid recovery and improved survival. Survival benefit was significant in a dose-dependent manner even when infusion of the expanded cell therapy was delayed 3 days after lethal IR exposure. Most surviving mice (80%) demonstrated long-term in vivo persistence of donor T cells at low levels, and none had evidence of graft versus host disease. Furthermore, survival of donor-derived skin grafts was significantly prolonged in recipients rescued from h-ARS by infusion of the mismatched expanded cell product. These findings provide evidence that ex vivo expanded mismatched HSPCs can provide rapid, high-level hematopoietic reconstitution, mitigate IR-induced mortality, and convey donor-specific immune tolerance in a murine h-ARS model.
Structural insights into the molecular mechanism of the m6A writer complex
Authors: Śledź Paweł , Jinek Martin
Published: September 2016

Methylation of adenosines at the N6 position (m6A) is a dynamic and abundant epitranscriptomic mark that regulates critical aspects of eukaryotic RNA metabolism in numerous biological processes. The RNA methyltransferases METTL3 and METTL14 are components of a multisubunit m6A writer complex whose enzymatic activity is substantially higher than the activities of METTL3 or METTL14 alone. The molecular mechanism underpinning this synergistic effect is poorly understood. Here we report the crystal structure of the catalytic core of the human m6A writer complex comprising METTL3 and METTL14. The structure reveals the heterodimeric architecture of the complex and donor substrate binding by METTL3. Structure-guided mutagenesis indicates that METTL3 is the catalytic subunit of the complex, whereas METTL14 has a degenerate active site and plays non-catalytic roles in maintaining complex integrity and substrate RNA binding. These studies illuminate the molecular mechanism and evolutionary history of eukaryotic m6A modification in post-transcriptional genome regulation.

We show theoretically that a locally embedded Rashba interaction acts as a strong pinning center for current-driven domain walls and demonstrate efficient capturing and depinning of the wall using a weak Rashba interaction of the order of 0.01 eV Å. Our discovery is expected to be useful for highly reliable control of domain walls in racetrack memories.
Metaproteomics of saliva identifies human protein markers specific for individuals with periodontitis and dental caries compared to orally healthy controls

Published: September 2016

Background

The composition of the salivary microbiota has been reported to differentiate between patients with periodontitis, dental caries and orally healthy individuals. To identify characteristics of diseased and healthy saliva we thus wanted to compare saliva metaproteomes from patients with periodontitis and dental caries to healthy individuals.

Methods

Stimulated saliva samples were collected from 10 patients with periodontitis, 10 patients with dental caries and 10 orally healthy individuals. The proteins in the saliva samples were subjected to denaturing buffer and digested enzymatically with LysC and trypsin. The resulting peptide mixtures were cleaned up by solid-phase extraction and separated online with 2 h gradients by nano-scale C18reversed-phase chromatography connected to a mass spectrometer through an electrospray source. The eluting peptides were analyzed on a tandem mass spectrometer operated in data-dependent acquisition mode.

Results

We identified a total of 35,664 unique peptides from 4,161 different proteins, of which 1,946 and 2,090 were of bacterial and human origin, respectively. The human protein profiles displayed significant overexpression of the complement system and inflammatory markers in periodontitis and dental caries compared to healthy controls. Bacterial proteome profiles and functional annotation were very similar in health and disease.

Conclusions

Overexpression of proteins related to the complement system and inflammation seems to correlate with oral disease status. Similar bacterial proteomes in healthy and diseased individuals suggests that the salivary microbiota predominantly thrives in a planktonic state expressing no disease-associated characteristics of metabolic activity.

Published: September 2016

A conscientização quanto às questões ambientais tem influenciado a decisão de compra e os padrões de consumo que podem indicar a disposição em adquirir um produto com características ecológicas. Este estudo de caso pretende averiguar se investimentos em características ecológicas seriam capazes de trazer retornos financeiros positivos para uma indústria de água mineral de 510 ml. Para tal verificação as análises são feitas com base no modelo proposto por Bertolini (2009), que consistiu em identificar as características ecológicas mais percebidas pelos consumidores, avaliar a disponibilidade em adquirir o produto com tais características, analisar a viabilidade econômica do projeto, além de realizar cruzamentos entre as variáveis. Apurou-se que o fator preço ainda se sobrepõe à conscientização ecológica, e que o consumidor está disposto a pagar o mesmo preço tanto para produto ecológico, quanto para produto convencional. Mesmo diante dessas condições, pode-se dizer que a utilização da ferramenta de análise foi capaz de apontar viabilidade para investimentos em características ecológicas para o produto água mineral de 510 ml.

A literatura define projeto complexo como aquele que atende a determinadas e específicas características. Outro fator que pode levar um projeto a ser considerado complexo é a forma eficaz de gerenciar os riscos existentes, atividade esta que requer do gestor do projeto ações que vão além daquelas analíticas e simples. Este trabalho objetiva estudar a evolução do conhecimento científico sobre projetos complexos no período de 2003 a 2013. Para a realização deste trabalho foi realizado estudo através de documentação secundária, onde definiu-se o período a ser estudado, selecionadas as bases de dados a serem exploradas, identificados os periódicos com relevância para o tema projetos complexos, e identificados os artigos através do uso de palavras-chave. Os resultados sugerem que o tema projetos complexos ainda é incipiente, com publicações predominantemente efetuadas nos últimos cinco anos, em periódicos internacionais, concentradas em um pequeno grupo de autores que geraram a maior parte das citações.

A prática de coletar informações do meio evoluiu ao longo do tempo, e o advento tecnológico dos últimos anos gerou mudanças substanciais neste processo. A utilização de tecnologias cada vez menores e mais sofisticadas  para fins de vigilância, prevenção e militarização do espaço urbano é parte deste processo, e constitui a chamada smartsurveillance. No Brasil, o exemplo mais recente e de maiores proporções deste tipo de aplicação é a criação dos CICCs - Centros Integrados de Comando e Controle - para a Copa do Mundo FIFA 2014. Neste contexto, a presente pesquisa questiona de que forma ocorreram os processos de smartsurveillance implementados em cidades brasileiras na ocasião.  Objetiva-se identificar de que modo o aparato tecnológico para vigilância instalado vem sendo utilizado nas cidades de Recife e Curitiba, no sentido de aproveitar o legado do evento esportivo e de contribuir  para a gestão tecnológica do espaço urbano e para a  redução da criminalidade. A escolha dos estudos de caso ocorreu devido a critérios populacionais, de similaridade no número de jogos recebidos e de aproximações em rankings que medem índice de criminalidade urbana. A metodologia aplicada envolveu teoria e análise de discurso Laclau & Mouffe (1985), e critérios de caracterização da vigilância eletrônica Bruno (2012). Os resultados indicaram que em ambas as cidades, a implantação dos CICCs se assemelha a um tipo moderno de panóptico, o qual está baseado no discurso do combate aos problemas sociais e à violência urbana, além da relativa isenção da liberdade e do anonimato.

Regiões metropolitanas em nível mundial vêm enfrentando mudanças significativas em seus processos de uso e ocupação do solo tornando-as palco de conflitos socioambientais crescentes. Considerando que esses embates vêm ganhando expressão em regiões densamente ocupadas em nosso país, se delineou como objetivo desse estudo verificar as suas origens e formas de manifestação na Região Metropolitana de São Paulo (RMSP) com vistas a entendê-los, classificá-los e analisá-los. A questão norteadora da pesquisa foi: quais as origens dos principais conflitos socioambientais que se manifestam na Região Metropolitana de São Paulo e como eles podem ser classificados e analisados à luz da literatura existente? Como metodologia, este trabalho baseou-se em revisão bibliográfica e análise documental. Como resultado, constatou-se cinco origens ou formas de manifestação mais comuns, por vezes sobrepostas, relacionadas a: (i) urbanização periférica e desigual; (ii) operação urbana; (iii) ocupação irregular em áreas protegidas; (iv) danos e passivos ambientais; e (v) degradação de recursos hídricos. Observou-se que, não raro, suas origens e manifestações relacionam-se a deficiências na aplicação e gestão de políticas públicas. Além disso, constatou-se também uma diversidade considerável de abordagem desses conflitos, o que impõe desafios para organizar esta temática de acordo com um ou mais princípios teóricos.
Autoria científica: por que tanta polêmica?
Authors: L. Volpato Gilson
Published: September 2016

Os critérios para autoria científica ainda carecem de consenso entre cientistas, dando margem a especulações que, algumas vezes, apenas justificam o injustificável. Neste texto, meu foco é na ciência empírica e eu proponho que participações em coleta de dados (CD) ou fornecimento de recursos materiais (RM) para a pesquisa não são condições suficientes, nem necessárias, para se atribuir autoria em textos científicos. Após apresentar as bases teóricas dessa proposta, mostro dados que indicam que essas bases têm sido usadas em magnitude ampla na ciência internacional, o que torna o debate ainda mais relevante. Ao final proponho separar as participações na pesquisa científica em autoria, colaboração e agradecimento, de forma a valorizar cada grupo de atuação, sem perder suas peculiaridades. São elas: autoria, colaboração e agradecimento. Scientific authorship: why so much controversy?Criteria for scientific authorship still lack of universal consensus among scientists, thus rising speculations that, sometimes, only justify the unjustifiable. In this text, my focus is the empirical science and I propose that participation in data collection (DC) or provision of material resources (MR) for the research are neither sufficient, nor necessary, conditions to warrant authorship in scientific texts. After presenting the main theoretical bases of my argument, I show some data supporting that such participations (DC and/or MR) have been largely used for assignment of scientific authorship in the international literature, thus making this debate more relevant. Finally, I propose separate the participation in a scientific study in three classes: authorship, collaboration and acknowledgements, thus valorizing each of these participations, but not contradicting its peculiarities in the process of building scientific knowledge. keywords: Authorship; Scientific Publication; Scientific Knowledge.
The crustal structure beneath Mauritius from teleseismic P receiver functions: Oceanic or continental?
Authors: Singh Manvendra , Kaviani Ayoub , Rümpker Georg
Published: September 2016

It has recently been suggested that the volcanic island of Mauritius may be underlain by a remnant of continental origin termed “Mauritia.” To constrain the crustal thickness beneath Mauritius, we analyzed data from 11 land stations, 10 of which were deployed recently by the RHUM‐RUM project. From the recordings, we obtained 382 P receiver functions (RFs). By applying the H‐κ stacking technique, we derive crustal thicknesses of approximately 10–15 km. We observe a considerable variation in the Vp/Vs ratio caused by a lack of clear multiples. Using forward modeling of RFs, we show that the lack of clear multiples can be explained by a transitional Moho, where the velocity increases gradually. The modeling further indicates that the thickness of this gradient zone is estimated to be approximately 10 km. We argue that our findings suggest oceanic crust thickened by crustal underplating due to the mantle plume currently located beneath La Réunion.
Conjugate observations of a remarkable quasiperiodic event by the low‐altitude DEMETER spacecraft and ground‐based instruments

Published: September 2016

We present a detailed analysis of a long‐lasting quasiperiodic (QP) event observed simultaneously by the low‐altitude DEMETER spacecraft and on the ground by the instrumentation of the Sodankylä Geophysical Observatory, Finland. The event was observed on 26 February 2008. It lasted for several hours, and it was detected both in the Northern and Southern Hemispheres. The time intervals when the event was observed on board the satellite and/or on the ground provide us with an estimate of the event dimensions. When the event is detected simultaneously by the satellite and on the ground, the observed frequency‐time structure is generally the same. However, the ratio of detected intensities varies significantly as a function of the spacecraft latitude, indicating the wave guiding along the plasmapause. Moreover, there is a delay as large as about 13 s between the times when individual QP elements are detected by the spacecraft and on the ground. This appears to be related to the azimuthal separation of the instruments, and it is highly relevant to the identification of a possible source mechanism. We suggest that it is due to an azimuthally propagating ULF wave which periodically modulates the azimuthally extended source region. Finally, we find that at the times when the intensity of the QP event suddenly increases, there is a distinct increase of the amplitude of Alfvénic ULF pulsations measured on the ground at high latitudes. This might indicate that the source region is located at L shells larger than about 7.1.
Stability of magnetotail equilibria with a tailward Bz gradient
Authors: Merkin V. G. , Sitnov M. I.
Published: September 2016

Analytical properties of two‐dimensional magnetotail equilibria with a region of magnetic flux accumulation (a “Bz hump”) are considered with respect to tearing and interchange stability. Since the former mode does not initially involve a change in topology, we denote it the Magnetic Flux Release Instability (MFRI). The region earthward of the Bz peak is found most unstable to both modes due to the presence of a tailward Bz gradient there. Stability is studied as a function of proximity of the Bz accumulation region to Earth. Interchange is found more difficult to stabilize closer to Earth as the level of the background pressure required for stabilization is higher there. At the same time, the kinetic MFR mode has the largest potential for destabilization farther in the tail as long as the current sheet is sufficiently thin to allow Landau dissipation, while the tearing (MFRI) Cd parameter is sufficiently large. An MHD analog of the kinetic MFR mode is allowed still farther from Earth, and the regions of kinetic and MHD instability may overlap dependent on the parameters of the equilibrium. We provide analytical results describing the MFR stability as a function of a number of key parameters, including the level of current sheet stretching and its length, as well as the amplitude and the scale size of the Bz gradient.
