TINGKAT SERANGAN HAMA Phyllocnistis near citrella (LEPIDOPTERA: PHYLLOCNISTIDAE) PADA PERKEBUNAN MANGGIS DI DESA KARACAK, KECAMATAN LEUWILIANG, KABUPATEN BOGOR
Authors: Sari Wilna - 
Published: June 2017

<p><em>Phyllocnistis </em>near <em>citrella </em>atau hama pengorok daun merupakan salah satu hama yang dapat menyerang tanaman manggis, terutama pada masa <em>flush</em>. Hama ini mempunyai gejala serangan khas berupa liang korokan yang berlekuk-lekuk pada bagian daun yang lama kelamaan akan mengering. Salah satu dampak dari serangan hama ini adalah rendahnya kemampuan daun berfotosintesis, sehingga menyebabkan daun berkembang tidak sempurna. Penelitian ini dilakukan pada perkebunan manggis milik petani di Desa Karacak, Kabupaten Bogor yang banyak ditemukan serangan hama ini meski relatif rendah. Penelitian diutamakan pada bibit manggis yang berumur ± 2 tahun dan pohon manggis berumur 7-9 tahun. Penelitian bertujuan mengetahui tingkat serangan hama pengorok daun pada bibit dan pohon manggis. Selain itu juga mengetahui bentuk jaringan daun bekas korokan hama. Metode penelitian secara survey dan menentukan sampel tanaman yang akan diamati lalu dihitung tingkat serangan hama pada tanaman selama tiga kali masa <em>flush </em> di minggu ke dua dan empat. Berdasarkan penelitian tersebut diketahui bahwa hama merusak jaringan spons pada daun. Serangan <em>P.</em>near <em>citrella </em>di bibit manggis meningkat pada masa <em>flush </em>ke-1 dan 2 secara nyata pada minggu ke dua dan ke empat. Demikian juga halnya pada pohon manggis, dimana serangan hama meningkat nyata pada masa <em>flush </em>ke-1 dan 2 pada minggu ke dua dan ke empat, sedangkan pada masa <em>flush </em>ke -3 tidak berbeda nyata karena dipengaruhi oleh faktor hujan. </p>

Esta investigación es la segunda parte del artículo “Prestadores de Servicios de apoyo a la exportación en la Comarca Lagunera”, publicado en la Revista Iberoamericana de Contaduría, Economía y Administración, vol.5, núm.10, donde se hace un recuento de los prestadores del servicio logístico.El éxito, la reduc­ción de costes y la satisfacción de los clientes de una organización depen­den de un sistema logístico bien gestiona­do, integrado y flexible, controlado en tiempo real y donde fluye la información de manera eficiente (IDE-CESEM, 2017).El objetivo de esta investigación es medir la calidad de los servicios logísticos en la Comarca Lagunera de acuerdo a tres dimensiones: conformidad, desempeño y confiabilidad, las cuales a su vez se desglosan en tres áreas: transporte, oficinas gubernamentales e instituciones financieras.Los principales resultados fueron: 35 % de las empresas encuestadas realiza tanto exportaciones como importaciones, 36 % solamente exporta y 29 % importa; asimismo, 54 % realiza operaciones de comercio exterior con una frecuencia semanal y el restante 46 % de manera mensual.Los empresarios señalan que las áreas donde más les afecta la falta de confiabilidad y el desempeño de sus prestadores de servicio son el transporte y la distribución de los productos. Su dificultad para manejar niveles adecuados en el almacén proviene de la incertidumbre con respecto al transporte y los tiempos de recepción de la materia prima.En términos generales, la oportunidad de mejorar la calidad de los servicios asciende a 57 %, mientras que las áreas de transporte aéreo y servicios financieros alcanzaron la calificación más baja. Por otro lado, 37 % de los exportadores e importadores considera que el precio que pagan por el transporte es elevado dada la contraprestación que reciben. Otro resultado importante es que 56 % de las empresas encuestadas afirma que no conoce fuentes de financiamiento para la exportación y/o importación, dato confirmado con el ITEM 14 (¿Conoce los servicios que ofrece Bancomext, Pro México?), el cual arrojó que 4 de cada 10 empresas no conocen la gama de servicios que ofrecen estas instituciones.
Cuentas de orden

Published: June 2017

El tema de las cuentas en orden debería ser estudiado con mayor amplitud y aunque la bibliografía específica no abunda, dada la importancia que reviste, el presente trabajo tiene como propósito realizar un acercamiento que contribuya al desarrollo de la disciplina. Partimos del reconocimiento de la contabilidad como un lenguaje, teniendo como base el surgimiento del paradigma de utilidad, y la revelación como prioridad, se planeta como las cuentas de orden tienen la posibilidad de complementar la información a terceros; reconociendo aquellos hechos que si bien no afectan la situación financiera del ente económico, pueden afectarlo en el futuro. En consecuencia, las cuentas de orden, forman parte de la estrategia de revelación plena, concebida en el ordenamiento colombiano. Y si no son de obligatoria utilización, es prudente que los contadores públicos las conozcan y reconozcan su aplicación. Se busca por tanto dar soporte teórico, jurídico e ilustrar brevemente su aplicación.
Distal demonstratives licensed by culturally-familiar scenarios
Authors: Doran Ryan , Ward Gregory 
Published: June 2017

Previous work on English demonstratives (Gundel et al. 1993, Diessel 1999) has shown that distal demonstratives may be used to indicate information status. In this paper, we investigate a use of distal demonstratives that is licensed by (presumed) shared knowledge of culturally-familiar scenarios, rather than by private shared knowledge of particular entities, as exemplified in (1):(1) I’m not really fit to talk in the morning until I’ve had that first cup of coffee. [corpus]Here, the entity specified by the demonstrative NP stands proxy for the familiar routine of beginning’s one day and no specific cup of coffee is being referred to. We show that, by using the demonstrative in this way, the speaker presumes that the hearer is a member of community in which the relevant scenario is familiar.

Abstract
The summit of the Antarctic plateau, Dome A, is proving to be an excellent site for optical, near-infrared, and terahertz astronomical observations. Gattini is a wide-field camera installed on the PLATO instrument module as part of the Chinese-led traverse to Dome A in 2009 January. We present here the measurements of sky brightness with the Gattini ultra-large field of view (

) in the photometric B-, V-, and R-bands; cloud cover statistics measured during the 2009 winter season; and an estimate of the sky transparency. A cumulative probability distribution indicates that the darkest 10% of the nights at Dome A have sky brightness of S

B
= 22.98, S

V
= 21.86, and S

R
= 21.68 mag arcsec−2. These values were obtained during the year 2009 with minimum aurora, and they are comparable to the faintest sky brightness at Maunakea and the best sites of northern Chile. Since every filter includes strong auroral lines that effectively contaminate the sky brightness measurements, for instruments working around the auroral lines, either with custom filters or with high spectral resolution instruments, these values could be easily obtained on a more routine basis. In addition, we present example light curves for bright targets to emphasize the unprecedented observational window function available from this ground-based site. These light curves will be published in a future paper.
The O2 A-Band in the Fluxes and Polarization of Starlight Reflected by Earth-Like Exoplanets
Authors: Fauchez Thomas , Rossi Loic , Stam Daphne M. 
Published: June 2017

Abstract
Earth-like, potentially habitable exoplanets are prime targets in the search for extraterrestrial life. Information about their atmospheres and surfaces can be derived by analyzing the light of the parent star reflected by the planet. We investigate the influence of the surface albedo A
s, the optical thickness b
cloud, the altitude of water clouds, and the mixing ratio of biosignature O2 on the strength of the O2 A-band (around 760 nm) in the flux and polarization spectra of starlight reflected by Earth-like exoplanets. Our computations for horizontally homogeneous planets show that small mixing ratios (η < 0.4) will yield moderately deep bands in flux and moderate-to-small band strengths in polarization, and that clouds will usually decrease the band depth in flux and the band strength in polarization. However, cloud influence will be strongly dependent on properties such as optical thickness, top altitude, particle phase, coverage fraction, and horizontal distribution. Depending on the surface albedo and cloud properties, different O2 mixing ratios η can give similar absorption-band depths in flux and band strengths in polarization, especially if the clouds have moderate-to-high optical thicknesses. Measuring both the flux and the polarization is essential to reduce the degeneracies, although it will not solve them, especially not for horizontally inhomogeneous planets. Observations at a wide range of phase angles and with a high temporal resolution could help to derive cloud properties and, once those are known, the mixing ratio of O2 or any other absorbing gas.

Published: June 2017

Abstract
How the solar corona is heated to high temperatures remains an unsolved mystery in solar physics. In the present study we analyze observations of 50 whole active region loops taken with the Extreme-ultraviolet Imaging Spectrometer on board the Hinode satellite. Eleven loops were classified as cool loops (<1 MK) and 39 as warm loops (1–2 MK). We study their plasma parameters, such as densities, temperatures, filling factors, nonthermal velocities, and Doppler velocities. We combine spectroscopic analysis with linear force-free magnetic field extrapolation to derive the 3D structure and positioning of the loops, their lengths and heights, and the magnetic field strength along the loops. We use density-sensitive line pairs from Fe xii, Fe xiii, Si x, and Mg vii ions to obtain electron densities by taking special care of intensity background subtraction. The emission measure loci method is used to obtain the loop temperatures. We find that the loops are nearly isothermal along the line of sight. Their filling factors are between 8% and 89%. We also compare the observed parameters with the theoretical Rosner–Tucker–Vaiana (RTV) scaling law. We find that most of the loops are in an overpressure state relative to the RTV predictions. In a follow-up study, we will report a heating model of a parallel-cascade-based mechanism and will compare the model parameters with the loop plasma and structural parameters derived here.
Stratified Simulations of Collisionless Accretion Disks
Authors: Hirabayashi Kota , Hoshino Masahiro 
Published: June 2017

Abstract
This paper presents a series of stratified-shearing-box simulations of collisionless accretion disks in the recently developed framework of kinetic magnetohydrodynamics (MHD), which can handle finite non-gyrotropy of a pressure tensor. Although a fully kinetic simulation predicted a more efficient angular-momentum transport in collisionless disks than in the standard MHD regime, the enhanced transport has not been observed in past kinetic-MHD approaches to gyrotropic pressure anisotropy. For the purpose of investigating this missing link between the fully kinetic and MHD treatments, this paper explores the role of non-gyrotropic pressure and makes the first attempt to incorporate certain collisionless effects into disk-scale, stratified disk simulations. When the timescale of gyrotropization was longer than, or comparable to, the disk-rotation frequency of the orbit, we found that the finite non-gyrotropy selectively remaining in the vicinity of current sheets contributes to suppressing magnetic reconnection in the shearing-box system. This leads to increases both in the saturated amplitude of the MHD turbulence driven by magnetorotational instabilities and in the resultant efficiency of angular-momentum transport. Our results seem to favor the fast advection of magnetic fields toward the rotation axis of a central object, which is required to launch an ultra-relativistic jet from a black hole accretion system in, for example, a magnetically arrested disk state.
Lensing of Fast Radio Bursts by Plasma Structures in Host Galaxies

Published: June 2017

Abstract
The amplitudes of fast radio bursts (FRBs) can be strongly modulated by plasma lenses in their host galaxies, including that of the repeating FRB 121102 at ∼1 Gpc luminosity distance. Caustics require the lens’ dispersion measure depth (

), scale size (a), and distance from the source (

) to satisfy

. Caustics produce strong magnifications (

) on short timescales (

hours to days) that appear as narrow spectral peaks (0.1–1 GHz). They also suppress the flux density in longer-duration (∼months) troughs. Multiply imaged bursts will arrive differentially by

to tens of ms with different apparent dispersion measures,

pc cm−3. When differing by less than the burst width, interference effects in dynamic spectra will be seen. Larger arrival time perturbations may mask any underlying periodicity with period

. Strong lensing requires sources smaller than

, which includes compact objects such as neutron star magnetospheres but excludes active galactic nuclei. We discuss constraints on densities, magnetic fields, and locations of plasma lenses related to the conditions needed for lensing to occur. Much of the phenomenology of the repeating FRB source FRB 121102 can be accounted for in this picture, which can be tested by obtaining wideband spectra of bursts (from

to 10 GHz and possibly higher) that will also help characterize the plasma environment near FRB sources. A rich variety of phenomena is expected from an ensemble of lenses near an FRB source.
Les titres fonciers autour de Bamako : modes d’accès et impacts sur les usages
Authors: Camara Fatoumata 
Published: June 2017

Dans les communes environnantes de Bamako, les ressources naturelles, particulièrement les terres agricoles, sont soumises à une forte pression. Celle-ci se manifeste par une augmentation croissante du nombre de titres fonciers (TF) pendant ces dernières années. Les communes périurbaines de Bamako comptaient en décembre 2010 43 694 TF avec une superficie de 56 164 hectares, 83 ares et 59 centiares. L’augmentation significative des TF profite peu ou pas à la production agricole. Les usages de la terre étant constamment modifiés, les terres acquises par les nouveaux acquéreurs (les Bamakois) sont utilisées dans la plupart des cas comme un moyen de thésaurisation foncière pour de futurs terrains d’habitations. C’est ainsi qu’environ 70 % des TF ont vocation d’habitation. L’approvisionnement des populations bamakoises en céréales et légumes, que les paysans assuraient tant bien que mal, se détériore, anéantissant les effets bénéfiques d’une sécurisation foncière par voie d’immatriculation.
An assessment of consumers’ subconscious responses to frontline employees’ attractiveness in a service failure and recovery situation
Authors: Boshoff Christo 
Published: June 2017

Background: Initial analyses of the impact of physical attractiveness in a business context have supported the ‘what is beautiful is good’ contention. However, in circumstances characterised by negative emotions, duress and stress, very little is known about how human beings respond at the subconscious level to the attractiveness of frontline service providers.Aim: The purpose of this study was to assess whether consumers who complain to a frontline service provider about a service failure respond differently at the subconscious level when the service provider involved in the service encounter is attractive compared with one who is less attractive.Method: Forty respondents were exposed to a video clip of a service failure and service recovery situation. While viewing the hypothetical scenario, two neuro-physiological measurements were used to collect data at the subconscious level, namely galvanic skin response (GSR) and electroencephalography (EEG).Results: The results suggest that, at the subconscious level, customers respond differently to the service recovery efforts depending on the attractiveness of the frontline service provider who attempts to rectify the service failure.Conclusion: The results seem to suggest that the physical attractiveness of a frontline service provider moderates (or softens) the negative emotions that a complaining customer might experience during a service failure and complaint situation – consistent with the ‘what is beautiful is good’ contention.

This study is a contribution to the development of adsorption techniques for the removal of fluoride in natural waters. The work is carried out on a laboratory scale using local geo-materials sorbents, on the one hand the residues from the treatment of natural phosphorite of Hahotoé-Kpogamé and on the other hand the attapulgite clay mineral from the costal basin of Togo. The work carried out concerns the adsorption of fluoride on those sorbents. The following parameters are batch tested on synthetic fluoride solutions: time, solution pH, geo-material dose and fluoride concentration. The fluoride is analyzed by absorption spectrometry. The adsorption yields on the phosphorite treatment residues for aqueous fluoride solutions at an initial concentration of 10 mg/L and an adsorbent concentration of 10 g/L are 49 % at pH 6.5 and 66 % at pH 4.0. In the same experimental conditions, the yields on clay minerals are 28.2 % and 36.3 %. These yields are logically improved by increasing the adsorbent dosage (from 2 to 30 g/L). Additional tests are carried out on natural water at an initial fluoride concentration of 3.76 mg/L.
Cette étude est une contribution au développement de techniques d’adsorption pour l’élimination du fluor dans les eaux naturelles. Les travaux ont été réalisés à l’échelle du laboratoire en utilisant comme sorbants des géo-matériaux locaux, d’une part les résidus du traitement des phosphates naturels de Hahotoé-Kpogamé et d’autre part l’argilite feuilletée du bassin sédimentaire côtier du Togo. Les travaux réalisés concernent l’adsorption du fluor sur les sorbants considérés. Les paramètres suivants ont été testés en batch sur des solutions synthétiques de fluor : le temps, le pH de la solution, la dose du géo-matériau et la concentration du fluor. Le fluor a été dosé par spectromètrie d’absorption. Les rendements d’adsorption sur les résidus de traitement des phosphates pour des solutions aqueuses de fluor à concentration initiale de 10 mg/L et une concentration en adsorbant de 10 g/L ont été de 49 % à pH 6,5 et 66 % à pH de 4,0. Dans les mêmes conditions expérimentales, les rendements sur les argilites ont été de 28,2 % et 36,3 %. Ces rendements ont logiquement été améliorés en augmentant le dosage en adsorbant (de 2 à 30 g/L). Des essais complémentaires ont été réalisés sur une eau naturelle à une concentration initiale en fluor de 3,76 mg/L.

Published: June 2017

The dredging of the French harbors generates every year between 25 and 40 million tons of sediments, however few adapted treatment and valorization systems exist. Consequently, numerous research programs emerged such as SEDiGEST, which envisaged a scenario of backfill of the careers by treated marine sediments.The objective of this article is to assess results of the marine sediment terrestrial valorization systems in order to better identify the most impacting part of the systems. The assessment has been performed following the life cycle assessment (LCA) methodology via the GaBi 6 software, EcoInvent v2.2 databases with the characterization method ReCiPe.In the backfill scenario, the comparative study of the two treatments within the same terrestrial valorization system concluded that the addition of the stabilization step with hydraulic binders seems not to be beneficial and do not reduce the potential environmental impacts.
Le dragage des ports français génère chaque année entre 25 et 40 millions de tonnes de sédiments, cependant peu de filières de traitement et de valorisation adaptées existent. Par conséquence, de nombreux programmes de recherche ont émergé tel que le programme SEDiGEST qui envisageait un scénario de remblaiement des carrières par des sédiments marins traités.L’objectif de cet article est d’évaluer les impacts environnementaux de cette filière de valorisation terrestre de sédiments marins afin de mieux identifier les processus les plus pénalisants. L’évaluation a été réalisée en utilisant une Analyse de Cycle de Vie (ACV) via l’outil GaBi 6, la base de données Ecoinvent v2.2 et la méthode de caractérisation ReCiPe.Dans le scénario de remblaiement de carrière, l’étude comparative de deux alternatives au sein d’une même filière de valorisation terrestre a ainsi permis de conclure que l’ajout d’une étape de stabilisation par des liants hydrauliques ne semble pas bénéfique et ne permet pas de réduire les impacts environnementaux potentiels.
