Background: Whole body vibration (WBV) exercise has been used in health sciences. Authors have reported that
changes on the concentration of plasma biomarkers could be associated with the WBV effects. The aim of this
investigation is to assess the consequences of exposition of 25 Hz mechanical vibration generated in
oscillating/vibratory platform (OVP) on the concentration of some plasma biomarkers and on the weight of rats.
Materials and Methods: Wistar rats were divided into two groups. The animals of the Experimental Group (EG) were
submitted to vibration (25 Hz) generated in an OVP with four bouts of 30 seconds with rest time of 60 seconds between
the bouts. This procedure was performed daily for 12 days. The animals of the control group (CG) were not exposed to
vibration.
Results: Our findings show that the WBV exercise at 25 Hz was not capable to alter significantly (p
Multilevel method to compute the lambda modes of the neutron diffusion equation

Published: July 2017

Abstract
Determination of the reactor kinetic characteristics is very important for the design and development of a new reactor system. In this sense, the computation of lambda modes associated to a nuclear power reactor has interest since these modes can be used to analyze the reactor criticality and to develop modal methods to analyze transient situations in the reactor. In this paper, the lambda problem has been discretized using a high order finite element method to obtain a generalized algebraic eigenvalue problem. A multilevel method is proposed to solve this generalized eigenvalue problem combining a hierarchy of meshes with a Modified Block Newton method. The Krylov-Schur method is used to compare the efficiency of the multilevel method solving several benchmark problems.
A Phase-Behavior Study for n-Hexane/Bitumen and n-Octane/Bitumen Mixtures

Published: July 2017

Summary
Steam/solvent coinjection has been studied as a potential method to improve the efficiency of conventional steam-assisted gravity drainage (SAGD) for bitumen recovery. This research is part of an experimental program for phase behavior of Athabasca-bitumen/solvent mixtures.
This paper presents a new set of experimental data for phase equilibrium, viscosity, density, and asphaltene precipitation for 11 mixtures of Athabasca bitumen with n-hexane and 10 mixtures of the same bitumen with n-octane. Phase-boundary measurements were conducted at temperatures up to 160°C and pressures up to 10 MPa. The bitumen sample used in this research was studied in our previous research, in which the same bitumen was not effectively diluted by n-butane because of the coexistence of a butane-rich liquid with a bitumen-rich liquid phase.
In this research, the liquid/liquid separation of hydrocarbons was not observed for n-hexane/bitumen (HB) and n-octane/bitumen (OB) mixtures for the range of temperatures and pressures tested, even at solvent concentrations higher than 90 mol%. This observation indicates that the amount of solvent available near the edge of a steam chamber is expected to be entirely used for bitumen dilution beyond the chamber edge in coinjection of steam with heavier hydrocarbon solvents, such as n-hexane and n-octane.
Experiments for asphaltene precipitation at atmospheric pressure showed a larger amount of precipitates with n-hexane than with n-octane at a given solvent concentration higher than 50 wt%. For solvent concentrations less than 50 wt%, no asphaltene precipitation was observed for both solvents with the bitumen sample tested in this research.

Penggunaan rumus perhitungan faktor kompressibilitas gas alam secara manual dan hanya menggunakan satu parameter saja yaitu tekanan (Pa) oleh pihak penjual gas untuk pelanggan rumah tangga mengakibatkan adanya ketidaknyamanan dan pertanyaan dari masyarakat sebagai pelanggan gas terhadap keakuratan, keabsahan dan kehandalan rumus tersebut dikarenakan seharusnya faktor kompressibilitas gas alam dipengaruhi juga oleh suhu (Ta). Penelitian ini dilakukan di badan metrologi gas jakarta yang mempunyai standar internasional yaitu EN 12405 dan AGA NX19. Data yang didapat kemudian diolah dan dianalisa menggunakan program SPSS versi 16. Berdasarkan hasil pengolahan data dan analisa tersebut didapat bahwa suhu (Ta) juga mempunyai pengaruh terhadap faktor kompressibilitas (Zb/Zm) akan tetapi karena nilainya sangat kecil sekali maka pengaruh ini dapat diabaikan.
Nonthermal Particle Acceleration in 3D Relativistic Magnetic Reconnection in Pair Plasma
Authors: Werner Gregory R. , Uzdensky Dmitri A. 
Published: July 2017

Abstract
As a fundamental process converting magnetic to plasma energy in high-energy astrophysical plasmas, relativistic magnetic reconnection is a leading explanation for the acceleration of particles to the ultrarelativistic energies that are necessary to power nonthermal emission (especially X-rays and gamma-rays) in pulsar magnetospheres and pulsar wind nebulae, coronae and jets of accreting black holes, and gamma-ray bursts. An important objective of plasma astrophysics is therefore the characterization of nonthermal particle acceleration (NTPA) effected by reconnection. Reconnection-powered NTPA has been demonstrated over a wide range of physical conditions using large 2D kinetic simulations. However, its robustness in realistic 3D reconnection—in particular, whether the 3D relativistic drift-kink instability (RDKI) disrupts NTPA—has not been systematically investigated, although pioneering 3D simulations have observed NTPA in isolated cases. Here, we present the first comprehensive study of NTPA in 3D relativistic reconnection in collisionless electron–positron plasmas, characterizing NTPA as the strength of 3D effects is varied systematically via the length in the third dimension and the strength of the guide magnetic field. We find that, while the RDKI prominently perturbs 3D reconnecting current sheets, it does not suppress particle acceleration, even for zero guide field; fully 3D reconnection robustly and efficiently produces nonthermal power-law particle spectra closely resembling those obtained in 2D. This finding provides strong support for reconnection as the key mechanism powering high-energy flares in various astrophysical systems. We also show that strong guide fields significantly inhibit NTPA, slowing reconnection and limiting the energy available for plasma energization, yielding steeper and shorter power-law spectra.
A Flaring Magnetar in FRB 121102?
Authors: Beloborodov Andrei M. 
Published: July 2017

Abstract
The persistent radio counterpart of fast radio burst (FRB) 121102 is estimated to have

particles, energy

erg, and size

cm. The source can be nebula inflated and heated by an intermittent outflow from a magnetar—a neutron star powered by its magnetic (rather than rotational) energy. The object is young and frequently liberating energy in magnetic flares driven by accelerated ambipolar diffusion in the neutron star core, feeding the nebula and producing bright millisecond bursts. The particle number in the nebula is consistent with ion ejecta from giant flares. The nebula may also contain the freeze-out of electron–positron pairs

created months after the neutron star birth; the same mechanism offers an explanation for

in the Crab Nebula. The persistent source around FRB 121102 is likely heated by magnetic dissipation and internal waves excited by the magnetar ejecta. The volumetric heating by waves explains the nebula’s enormous efficiency in producing radio emission. The repeating radio bursts are suggested to occur much closer to the magnetar, as a result of ultrarelativistic internal shocks in the magnetar wind, which are launched by the magnetospheric flares. The shocks are mediated by Larmor rotation, which forms a GHz maser with the observed ms duration. Furthermore, the flare ejecta can become charge-starved and then convert to electromagnetic waves.

Published: July 2017

Os cães e os gatos convivem próximos aos seres humanos a aproximadamente 12 mil e 4 mil anos atrás, respectivamente. Nessa relação inúmeros benefícios são relatados para a saúde física e psicológica de ambas as partes, demonstrando auxiliar desde a redução do estresse e da pressão sanguínea até facilitar o contato social entre pessoas, diminuindo assim gastos com a saúde e melhorando aspectos do bem estar humano e animal. Porém, quando essa relação não é acompanhada pelo correto conhecimento sobre cuidados básicos e sobre o comportamento natural ou alterado dos cães e gatos, problemas sérios podem surgir como àqueles relacionados aos agravos causados por animais, por exemplo, que geram ferimentos e/ou que, podem facilitar a transmissão de zoonoses, importantes para a saúde pública. Assim, destaca-se a importância do estudo do comportamento de animais de estimação, em especial os cães e os gatos, na tentativa de auxiliar a amenizar essas situações indesejadas. Também busca-se inserir o médico veterinário neste contexto, por ser um profissional que possui habilitação para transmitir informações sobre o comportamento de cães e gatos e guarda responsável desses animais. A integração entre os serviços médicos e médicos veterinários deve ser um elo importante nesse trabalho, na tentativa de auxiliar nos trabalhos da Vigiliância Epidemiológica e também na promoção da saúde pública.
Benefits and principles of the Biological Survey of Canada: a model for scientific cooperation
Authors: Danks H.V. 
Published: July 2017

AbstractFor 40 years, the Biological Survey of Canada (BSC) has encouraged and organised studies of the arthropod fauna of Canada, through the wide involvement of the scientific community and the leadership of an expert steering committee. The benefits of the BSC to science include the completion of major cooperative projects to acquire and synthesise knowledge (documenting faunas in the Yukon, Canadian grasslands, and other significant regions and habitats), the assembly and organisation of information and specimens, and improved communication among entomologists. Its efforts have led to valuable monographs, scientific briefs, newsletters, and other products summarised here, including documents that are also useful to those outside entomology. Key operating principles of the BSC are identified. In particular, decisions come from broadly based scientific considerations, an approach to understanding the fauna that guarantees the scientific relevance of the work and is not offset by political or other influences. Core work is planned over the long term to ensure collaboration, focus, efficiency, integrity, quality, productivity, and delivery. The achievements of the BSC over many years confirm the effectiveness of this model for scientific cooperation.

Published: July 2017

Introduction: We report a rare cause of keratitis, due to Cylindrocarpon lichenicola, in a farmer with keratomycosis. Despite the acknowledged virulence of this fungus, a suitable antifungal for its management was not accessible.Case presentation: A 67-year-old farmer presented with a two-week history of pain, mucopurulent discharge, redness and a corneal ulcer with a visual acuity of hand movement in the right eye. With a working diagnosis of infective keratitis, corneal scrapings were taken under a slit lamp biomicroscope for microbiological testing. Direct lactophenol cotton blue mounts revealed septate fungal hyphae, while fungal culture on Sabouraud dextrose agar at room temperature grew woolly mould phenotypically consistent with C. lichenicola.Management and outcome: The patient was started on hourly topical natamycin (5%), ciprofloxacin (0.3%), two-hourly instillation of tobramycin (0.3%) and atropine (1%) twice daily for three months following the isolation of the fungus. The eye healed with a corneal scar and no improvements in visual acuity.Discussion: This infection was difficult to manage due to the inaccessibility of a suitable antifungal, namely, voriconazole in our setting. Hence, there is a need for prompt identification and early institution of suitable antifungals in any patient with suspected keratomycosis.

Aim of study: This paper objective focuses on the contribution of multifunctional natural forest silviculture, incorporating both private and public product managements, to forest and woodland economics.Area of study: Spain and California (USA).Material and methods: This conceptual article has developed a critical revision of the existing literature on the main economic issues for multifunctional natural forest silviculture in the last decades.Main results: Multifunctional natural silviculture has secular roots as a local practice, but as a science of the natural environment applied to the economic management of forest lands it is still in the process of maturation. Timber silviculture remains the central concern of forest economics investment in scientific publications. By contrast, silvicultural modeling of the natural growth of firewood, browse and other non-timber forest products from trees and shrubs receives scant attention in scientific journals. Even rarer are publications on multifunctional natural silviculture for forest and woodland managements, including environmental services geared to people’s active and passive consumption. Under this umbrella, private environmental self-consumption is represented by the amenities enjoyed by private non-industrial landowners. As for environmental public products, the most relevant are carbon, water, mushrooms, recreation, landscape and threatened biodiversity.Research highlights: This paper is a good example for the conceptual research on forestry techniques and economic concepts applied to multifunctional silviculture in Mediterranean areas of Spain and California. The combination of technical knowledge and private and public economic behaviors definitively contributes to the multifunctional management of natural forest systems.
