Abstract
Cancer patients face an increased risk of arterial thromboembolism; however, it is uncertain when this excess risk begins. This study evaluated the risk of arterial thromboembolism before cancer diagnosis. Using the population-based Surveillance Epidemiology and End Results-Medicare linked dataset, we identified 374 331 patients ≥67 years of age with a new primary diagnosis of breast, lung, prostate, colorectal, bladder, uterine, pancreatic, gastric cancer, or non-Hodgkin lymphoma from 2005 through 2013. Cancer patients were individually matched by demographics and comorbidities to Medicare beneficiaries without cancer, who served as controls. Validated diagnosis codes were used to identify arterial thromboembolic events, defined as a composite of myocardial infarction or ischemic stroke. The Mantel-Haenszel estimator was used to compare risks of arterial thromboembolic events between cancer and noncancer groups during 30-day periods in the 360 days before date of cancer diagnosis. From 360 to 151 days before cancer diagnosis, the 30-day interval risks of arterial thromboembolic events were similar between cancer patients and matched controls. From 150 to 1 day before cancer diagnosis, the interval 30-day risks of arterial thromboembolic events were higher in cancer patients vs matched controls, progressively increasing as the cancer diagnosis date approached and peaking during the 30 days immediately before cancer diagnosis, when 2313 (0.62%) cancer patients were diagnosed with an arterial thromboembolic event vs 413 (0.11%) controls (odds ratio, 5.63; 95% confidence interval, 5.07-6.25). In conclusion, the risk of arterial thromboembolic events begins to increase 150 days before the date of cancer diagnosis in older persons and peaks in the 30 days before.

Published: December 2018

BackgroundTrauma and traumatic bereavement have well-known consequences for mental health, but little is known about long-term adjustment, particularly with respect to health-protective factors.AimsTo assess the levels of anxiety/depression and perceived social support among the survivors and the bereaved 26 years after the Scandinavian Star ferry disaster compared with expected levels from the general population.MethodAnxiety/depression and social support were assessed in face-to-face interviews with the survivors and the bereaved (N= 165, response rate 58%). Expected scores were calculated for each participant based on the means and proportions for each age and gender combination from a general population sample. We computed the ratio between expected and observed scores, standardised mean differences with 95% confidence intervals and standardised effect sizes.ResultsWe found an elevated level of anxiety/depression symptoms in the victims (Mdiff= 0.28, 95% CI 0.18, 0.38; effect size 0.43, 95% CI 0.31, 0.55) and a significant excess of individuals with a clinically significant level of symptoms. The observed level of perceived social support was significantly lower than that expected (Mdiff= −0.57, 95% CI −0.70, −0.44; effect size −0.73, 95% CI −0.89, −0.57). This was the case for both survivors and those who were bereaved and for both men and women.ConclusionsThis study reveals that disaster survivors and the bereaved reported elevated levels of anxiety and depression symptoms 26 years after the event. They also reported a markedly reduced level of social support. Traumas and post-traumatic responses may thus cause lasting harm to interpersonal relationships.Declaration of interestNone.
Theoretical Study on the Transition-Metal-Catalyzed Cycloadditions of 2H-Azirines with Alkynes: Implication of Carbenoid Intermediates
Authors: Yamamoto Yoshihiko 
Published: December 2018

Abstract
The ruthenium-catalyzed cycloadditions of 2,3-diphenyl-2H-azirine with dipropargyl ether or methyl 2-butynoate were investigated by performing density functional theory (DFT) calculations, and plausible mechanisms were proposed for each reaction. As the initial step, the oxidative coupling of dipropargyl ether and the oxidative addition of the 2H-azirine were first examined in order to explain the experimentally observed [3+2+2] vs. [3+2] selectivity. Subsequently, each step including the [3+2+2] and [3+2] cycloadditions was examined to determine the feasibility of these catalytic reactions. Moreover, the related gold-catalyzed [3+2] cycloaddition of an ynamide with 3-phenyl-2H-azirine was also evaluated using DFT calculations for comparison with the ruthenium-catalyzed [3+2] cycloaddition.

Published: December 2018

Abstract
Thiolate (SR)-protected metal clusters have been extensively studied by using various structural analysis methods since the start of research into these clusters. We have also studied these clusters based on common analysis methods used by many other research groups. However, we also have actively worked towards efficient application of high-performance liquid chromatography (HPLC) to study these clusters. Consequently, we have achieved high-resolution separations of several SR-protected gold and alloy clusters. By realizing such high-resolution separations, we have achieved a deeper understanding of a number of issues, including: 1) the transition size from bulk to non-bulk behavior in dodecanethiolate-protected gold clusters; 2) heteroatom substitution effects on the electronic structures and the dependence of isomer distributions on experimental conditions in hydrophobic SR-protected alloy clusters; 3) the mechanism of ligand-exchange reactions in hydrophobic metal clusters; and 4) the chemical composition of products in hydrophilic metal clusters. These results have clearly demonstrated that HPLC separation and analysis are extremely effective in helping to understand the fundamental properties of SR-protected metal clusters.

Published: December 2018

Abstract. Piophila casei (Linneus), known as the cheese skipper fly, is a sarcosaprophagous dipteran, meaning it has a wide range of feeding habits: proteins, decaying animal and vegetable matter, and feces. The biological aspects of P. casei are relevant to several fields, including forensic entomology and human and veterinary medicine. This work presents the ultrastructure characteristics of P. casei, compares the structures present during its development using light microscopy and Scanning Electron Microscopy (SEM) and reports the development time of eggs, larvae and pupae under controlled laboratory conditions (23°C, 60% relative humidity and 12 h of light). Colony of adults previously maintained in the laboratory (third generation) was used in this study. The morphology of the insect and of structures such as the cephalopharyngeal skeleton, the anterior and posterior spiracles and the structures and organs of the head, thorax and abdomen of the first, second and third instar larvae were characterized. The total development time of the egg from laying until the emergence of the adult was 448 hours (18.66 days); this included 8 hours for embrionary development, 248 hours for larval development and 192 hours for pupal development.Ultraestrutura e tempo de desenvolvimento de estágios imaturos de Piophila casei (Linneus)Resumo.

Study of Weakly nonlinear Mass transport in Newtonian Fluid with Applied Magnetic Field under Concentration/Gravity modulation
Authors: Keshri Om Prakash , Gupta Vinod K. , Kumar Anand 
Published: December 2018

AbstractIn the present paper, a weakly nonlinear stability analysis is used to analyze the effect of time-periodic concentration/gravity modulation on mass transport. We have considered an infinite horizontal fluid layer with constant appliedmagnetic flux salted from above, subjected to an imposed time-periodic boundary concentration (ITBC) or gravity modulation (ITGM). In the case of ITBC, the concentration gradient between the plates of the fluid layer consists of a steady part and a time-dependent oscillatory part. The concentration of both walls is modulated. In the case of ITGM, the gravity fleld consists of two parts: a constant part and an externally imposed time periodic part, which can be realized by oscillating the fluid layer. We have expanded the infinitesimal disturbances in terms of power series of an amplitude of modulation, which is assumed to be small. Ginzburg-Landau equation is derived for dinding the rate of mass transfer. Effect of various parameters on the mass transport is also discussed. It is found that the mass transport can be controlled by suitably adjusting the frequency and amplitude of modulation.
Steady Fully Developed Mixed Convection Flow in a Vertical Channel with Heat and Mass Transfer and Temperature-Dependent Viscosity: An Exact Solution
Authors: Jha Basant K. , Oni Michael O. 
Published: December 2018

Abstract
An exact solution for mixed convection flow with temperature-dependent viscosity in a vertical channel subject to wall asymmetric heating and concentration is obtained. The momentum, concentration, and energy equations governing the flow configuration are derived and solved exactly by incorporating the variable viscosity term, which is assumed to exponentially decrease/increase with temperature difference into the momentum equation. The roles of governing parameters are depicted with the aid of tables and line graphs. Results show that buoyancy ratio parameter can bring about the occurrence of flow reversal at the walls. It is also found that heat transfer, total species rate, skin friction, and reverse flow occurrence are enhanced in the presence of temperature-dependent viscosity.

Abstract
The presence of heavy metals in water causes serious problems and their treatment before incorporating into the water body is a challenge for researchers. The present study was conducted to compare the sorption study of Ni (II) using silica gel, amberlite IR-120 and sawdust of mulberry wood in batch system under the influence of pH, initial Ni (II) concentration and contact time. It was observed that sorption process was depending upon pH and maximum sorption was achieved at pH 7.0. Kinetic data were well fitted into pseudo-second order kinetic model due to high R2 values and closeness of experimental sorption capacity and calculated sorption capacity of pseudo-second order. Isotherms study showed that Langmuir is one of the most suitable choices to explain sorption data due to high R2 values. The monolayer sorption capacities of silica gel, amberlite IR-120 and sawdust were found to be 33.33, 25.19, and 33.67 mg g−1, respectively. Desorption study revealed that NaCl is one of the most appropriate desorbent. It may be concluded from this study that sawdust is a suitable sorbent due to low cost, abundant availability and recycling of the materials for further study.

Diálogos entre Teoria e Literatura: A escrita de Freud
Authors: Rodrigues Larissa de Assis Pimenta 
Published: December 2018

Este artigo investiga as possibilidades de uma escrita da história com abordagem interdisciplinar, explorando a categoria de escrita cunhada por Sigmund Freud como “Ficção Teórica”. Esta modalidade de escrita é encontrada nos escritos de Freud principalmente ao relatar casos clínicos nos quais ele lançava mão de recursos literários para compor verdadeiros contos que articulavam ficção e teoria psicanalítica. Tal escrita suscita interpretações para além do que foi pretendido transmitir, como traços culturais ou aspectos subjetivos da época e dos indivíduos. Isto é, ela seria capaz de revelar elementos de um inconsciente coletivo, através de vocábulos usados, escolha de temas, valores morais, etc. Portanto, a ficção teórica não é uma nova forma de teorização, mas suscita interpretações e produz sentidos que seriam imprevistos pela teoria pura. Palavras-chave: Ficção teórica, literatura, psicanálise. AbstractThis article intends to investigate the the writing of History with an interdisciplinary approach, exploring the category of writing coined by Sigmund Freud as "Theoretical Fiction". This kind of writing is found in Freud's reports of his clinical cases, in which he used literary resources to compose true tales articulating fiction and psychoanalytic theory. This writing raises interpretations beyond what was intended to convey, such as cultural traits or subjective aspects from the periods and its individuals. That is, it would be able to reveal elements of a collective unconscious through used words, choice of themes, moral values, etc. Therefore, Theoretical Fiction is not a new form of theorizing but it raises interpretations and produces meanings that would be unforeseen by pure theory.Keywords: Theoretical Fiction, literature, psychoanalysis.
A Noisy Analog-to-Digital Converter Connects Cytosolic Calcium Bursts to Transcription Factor Nuclear Localization Pulses in Yeast
Authors: Hsu Ian S , Strome Bob , Plotnikov Sergey , Moses Alan M 
Published: December 2018

Abstract
Several examples of transcription factors that show stochastic, unsynchronized pulses of nuclear localization have been described. Here we show that under constant calcium stress, nuclear localization pulses of the transcription factor Crz1 follow stochastic variations in cytosolic calcium concentration. We find that the size of the stochastic calcium bursts is positively correlated with the number of subsequent Crz1 pulses. Based on our observations, we propose a simple stochastic model of how the signaling pathway converts a constant external calcium concentration into a digital number of Crz1 pulses in the nucleus, due to the time delay from nuclear transport and the stochastic decoherence of individual Crz1 molecule dynamics. We find support for several additional predictions of the model and suggest that stochastic input to nuclear transport may produce noisy digital responses to analog signals in other signaling systems.

La hidroxiapatita sintética es un biomaterial ampliamente utilizado en los procedimientos de regeneración ósea guiada. Objetivo: Sintetizar hidroxiapatita sintética a partir de la cáscara de huevo bajo distintos precipitados de ácido nítrico. Métodos: Estudio experimental que obtuvo CaCO3 a partir de la pulverización de la cáscara de huevo (Gallus gallus). El carbonato fue titulado con tres concentraciones de ácido nítrico (5, 10 y 15%) y fosfato de amonio. De las mezclas se realizaron pruebas a distintas temperaturas de calcinación (150, 600, 700, 800 y 900 °C) y tiempos de calcinación (2, 4, 8 y 12 h). Se utilizó el análisis de difracción de rayos X para caracterizar la presencia de carbonato de calcio e hidroxiapatita. Resultados: De las distintas rutas de síntesis, la vía de precipitación de ácido nítrico por exceso al 15% más el carbonato de calcio calcinado a 700 °C durante 8 h ofreció los resultados más similares a la hidroxiapatita sintética al ser comparado con el patrón estándar comercial. Los picos de intensidad correspondieron a los ángulos 2θ: 20, 26, 33, 34, 40, 48 y 50 Conclusiones: El método de síntesis por precipitación utilizando como sustrato el carbonato de calcio proveniente de la cáscara de huevo más nitrato de calcio y ácido nítrico, evidenció ser adecuado y práctico para la síntesis de hidroxiapatita. Su uso puede ser replicado para los estudios de caracterización y respuesta toxicológica en modelos experimentales pre clínicos.
“I am Mother to my Plants”
Authors: Fallon Breann 
Published: December 2018

The tree stands as a sacred symbol in many faith traditions. Unsurprisingly, nature-based new religious movements are no exception. This article considers the manifestation of sacred trees in a number of religious traditions, including Australian Aboriginal and Torres Strait Islander spirituality, Abrahamic traditions, Ancient Egyptian religion, Buddhism, Hinduism, Norse mythology, the Shinto faith, and nature-based new religious movements. After this initial section, I present the findings of a fieldwork project undertaken in 2016. Using the survey as a tool, this project enquired into the use of trees, plants, and private gardens among practitioners from nature-based new religious movements. This survey makes use of both quantitative and qualitative survey methods, having been distributed to various nature-based new religious movements in New Zealand, Australia, Europe, the United States, and the United Kingdom. Despite extensive tree lore, these survey results present the tree as a peripheral plant in the practitioners' everyday practice, with the garden as a whole being more critical than any single variety of vegetation.

En el presente artículo se reconstruyen históricamente los territorios periurbanos de Córdoba, con foco en los destinados a la producción hortícola para suministro de la ciudad, sistematizando investigaciones y cartografía histórica del período. Se definen las condiciones que emergieron durante este –que incluyen procesos de ocupación, invasión y despojo– y se analiza cómo estas lo estructuran hasta hoy. Como resultado, se visibiliza el territorio periurbano como esencial para la ciudad, en cuanto a producción de alimentos y patrimonio paisajístico, humano y productivo. Se sistematiza una nueva cartografía de cada coyuntura histórica detectada en la investigación.
Abstract
The article makes a historical reconstruction of the peri-urban territories of Córdoba, with focus on those intended for the city’s food supply, systematizing research and historical cartography of the period. This allows us to define the structural conditions that emerged during this period, which include processes of occupation, invasion and dispossession that structure the territory until today. As a result, we see the peri-urban territory as essential for the city, in terms of food production and landscape, human and productive heritage. In addition, we provide a new cartography of each historical juncture detected.
