A new Sillago species, the black-banded sillago, Sillago nigrofasciatasp. nov., is described based on 302 specimens sampled from the southern coast of China. Morphological comparisons have been conducted between the new species and ten other Sillago species. The results show that the new species is characterized by a black mid-lateral band below the lateral line when fresh; other characteristics are similar to those of Sillago sihama but subtle differences exist on the swim bladder between Sillago nigrofasciata sp. nov. and S. sihama. A detailed description and illustrations are provided for the new species. The validity of this new species is also supported by a genetic comparison using sequences of the mitochondrial cytochrome c oxidase subunit I (COI) gene.

This writing is on the subject of “Pedestal bowl” and mainly focused on categorizing objects regarding shape-related differences, changes of those objects in timeline and the locations of Silla pottery in different historical periods. Pedestal bowl is Bowl with Pedestal attached to it, and it is recognized in two different sorts: Handle pedestal bowl, if it has Handle and Pedestal bowl, if it doesn t have Handle. In detailed categorization, Pedestal bowl can be called differently: Notched band with Pedestal bowl, if its body has Notched band and Patternless- bowl of heels if its body doesn t have Notched band. In other Silla pottery researches previously done, the term of Pedestal bowl is mixedly used with words such as Handle- cup and Pedestal dish, which contributes more difficulties to a recognition of changes of Silla pottery in a time frame. Sometimes, errors were encountered by researchers from Chronology of Pedestal dish because Silla pottery was mistakenly put in the same category with Pedestal dish. In those reasons, each specific sorts of Pedestal bowl need to be correctly recognized and examined along with Pedestal bowl, Long-neck jar, Short-neck jar as a sub-class sort of Silla pottery. In this review, the subjects are discussed as the following order. First, Pedestal bowl and Pedestal dish are put in different groups through the exact definition of terms, and Pedestal bowl is sub-categorized through comparisons of its shapes. Moreover, changes which can be observed from objects are reviewed in regards of time and marked in period terms, chronically. Finally, Pedestal bowl is studied in terms of its changes in a time frame, the specifics of which are based on chronical records of each sort, and tried to be located in the specific time slot in a larger category of Silla pottery. In the process of this study, I recognized that Notched band with Pedestal bowl and Patternless-bowl of heels are normally not discovered together in many cases. Moreover, Handle Pedestal bowl was considered to have gone through some periods of its changes in shapes which were similar to Notched band with Pedestal bowl, and those changes were accompanied by its decrease in size. Also, it was also seen that Pedestal dish and Long-neck jar were not normally buried together, and uncategorized middle or small sized tombs can be recognized chronically through studies of its Pedestal bowl.

A sample was selected from the IRAS Point Source Catalogue based on the following selection criteria: very red (“cold”) IRAS-colours: roughly F25/F12 > 2.5 and F60/F25 < 1.2; and low IR-variability: VAR < 30. These non-variable IR-sources may be stars that have evolved beyond the AGB (Asymptotic Giant Branch); a large fraction (40%) is associated with known planetary nebulae (Van der Veen and Habing, 1987, Astron. Astrophys., in press). To determine the nature of the other 60% additional observations were made mainly in the infrared: 1–13 μm, during 4 observing runs: ESO (La Silla, Chile) in July 1986 and June 1987; UKIRT (Hawaii) in August 1986 and June 1987. A total number of 58 sources was observed. A summary of the observations: -IR broad band photometry at 1.2, 1.6, 2.2, 3.8 and 4,6 μm for all 58 sources. -IR broad band photometry at 8.4, 9.7 and 12.8 μm for 19 sources. -IR small band photometry for 4 sources in the ranges 2–2.5 μm and 3–3.5 μm. -IR spectroscopy for 10 sources in the ranges 2–2.5 μm and 3–3.5 μm, -V, R, I observations (0.55, 0.7 and 0.9 μm) for 5 sources associated with a star of visual magnitude 8–9. These observations were carried out by D. de Winter (Amsterdam) with the 0.5-m ESO telescope at La Silla (Chile). -Walraven photometry (0.32, 0.36, 0.38, 0.43 and 0.54 μm) for 21 stars brighter than V = 15 and within 10“ from the IRAS position. These observations were carried out by M. van Haarlem (Leiden) with the 0.9-m Dutch telescope at La Silla (Chile).

In July 660, Silla-Tang allied forces destroyed Baekje. In 661, the Tang launched an attack on Goguryeo. The battle between Goguryeo and Tang from 661 to 662 was called the Second Go-Tang War. The Second Go-Tang War ended with the Battle of the Sasu in 662. In this study, the military base of the Tang army was specifically determined, and based on this, the defense battle was reconstructed. It is believed that the Sasu is located in the west, not east of Pyongyang Castle. The Tang army formed four camps to surround Pyongyang Castle. Bang Hyo-tae's troops were stationed in the west of Pyongyang Castle, installing a barrier along the shooter. Yoo Baek-young's unit was stationed on the left side of Bang Hyo-tae's unit, and Im Ah-sang and Jo Gye-sook's unit were stationed on the right side. And So Jeong-Bang is believed to have been stationed in the area of Maeup-san. Goguryeo troops first attacked Im Ah-sang's troops with weak defense facilities. When Im Ah-sang's unit was defeated, Bang Hyo-tae's unit was isolated and annihilated. As a result, the Tang army's siege of Pyongyang could no longer be maintained. In addition, the cold and food shortages were further aggravated by heavy snow at the time. In the end, the party forces, which received the military supplies supported by Silla, were relieved of the siege of Pyongyang and stepped down.

En los siglos XVI y XVII, el acondicionamiento interior de las iglesias parroquiales parisinas muestra una fuerte apropiación de las familias burguesas que tienen ahí su sepultura familiar y su banca privada. Los testadores indican el lugar preciso en el que desean ser inhumados y dan instrucciones para la organización de su funeral (Chaunu). En el siglo XVIII, las fábricas limitan los entierros bajo el pavimento, antes de que se construyan fosas colectivas destinadas a recibir los cuerpos de todos los feligreses burgueses y también reemplazan las bancas familiares por sillas. Los testamentos se vuelven lacónicos, porque, a partir de ese momento, el lugar de inhumación se impone de acuerdo con el rango social, así como con el tipo y monto de los gastos funerarios. Se instaura un conformismo funerario y la inhumación se convierte en una ceremonia familiar independiente de las cualidades personales del difunto.Abstract: In the XVI-XVIIth centuries, the interior fittings of Parisian parish churches show a strong ownership by the middle-class families, who have their graves and their pews in there. The testators specify where they wish to be buried and give instructions to organize their funerals (Chaunu). In the XVIIIth century, churchwardens restrict burials under the pavement before constructing large cellars to receive the corpses of the bourgeois; they also replace pews by chairs. Wills become brief because the burial site is now imposed both by social rank and the type and amount of funeral expenses. A funeral standard is established, burial becomes a family event independent of personal qualities of the deceased.Résumé : Aux XVIe-XVIIe siècles, l’aménagement intérieur des églises paroissiales parisiennes témoigne d’une forte appropriation par les familles bourgeoises qui y ont leur sépulture familiale et leur banc clos.

Un conformisme funéraire s’instaure, l’inhumation devient une cérémonie familiale indépendante des qualités personnelles du défunt.

A bipolar Herbig-Haro jet system associated with the emission-line object Th 28 has been discovered from direct CCD-imaging, long-slit spectroscopy, and broadband infrared observations. The observations were carried out using the facilities of the European Southern Observatory, La Silla, Chile. A direct CCD-image taken through a narrow band Hα interference filter is shown in Figure 1.

AbstractThe X-ray transient source XTE J1818–245 went through an outburst in 2005 that was observed during a multi-wavelength campaign from radio to soft γ-rays. We performed new optical observations with the ESO/NTT telescope at La Silla. The broad-band spectral energy distribution revealed that the outer parts of the accretion disc had to be irradiated by its inner parts to explain the optical emission.

AbstractHigh-angular resolution observations were acquired for a sample of F-G and K nearby orbital binaries, making use of the ADONIS instrument mounted at the 3.6m ESO telescope from La Silla observatory. The aim is to derive broad-band near-infrared colours for the individual components of those binaries which do not fit well the mean mass-luminosity relation, but which have accurate parallaxes (from the Hipparcos satellite) and high-quality orbits, thanks to many previous efforts. Such colour determinations allow component temperatures and photometric mass ratios to be derived.

High resolution (0.°25 × 0.°25) surface brightness distribution in V of the southern Milky Way over an area of 200° ≤ l ≤ 60° and of −30° ≤ b ≤ +30° was obtained by photographic plates, taken at La Silla, Chile, with the super-wide-angle camera with spherical mirror of the Astronomisches Institut der Ruhr-Universität Bochum (Schmidt-Kaler et al. 1983). Schmidt-Kaler et al. (1983) and Seidensticker, Schmidt-Kaler, and Schlosser (1982) carried out an analysis of these plates. However, these studies used only a fraction of the whole plate; interesting parts of the sky were chosen near the plate centers, thus minimizing various errors. The plates are now all scanned over the whole field of view with a PDS with a diaphragm of 50 × 50 μm = 0.°12 × 0.° 12 on the sky. The image size is 1201 × 1201 pixels per plate. The mean deviation during the scan time was less than 0.1%. Through the identification of about 50 stars and by using their l, b and x, y coordinates, the equations of the plates were solved with eight geometric parameters. The standard deviation of all parameters was less than 0.3 pixels on all plates.

La morphologie et la structure interne du banc de sillage de la Horaine sont décrites à partir de donnéesobtenues par sondeur multifaisceaux et sismique réflexion haute résolution, couplées à des données de vibrocarottage et datations au radiocarbone. La structure interne du banc révèle 4 unités sismiques (U1-U4) sur un socle protérozoïque (U0). L'unité basale U1 est interprétée comme des sédiments fluviatiles de bas niveau marin remaniés pour remplir les micro-incisions du socle protérozoïque lors la transgression holocène. Cette unité est recouverte par l’unité U2, mise en place par dérive littorale à la manière des flèches sableuses, dans un contexte de remontée rapide du niveau marin. L'unité U3 progradante est interprétée comme des dépôts d'inondation marine en continuité avec l'unité U2. L'unité U4 est caractérisée par des réflecteurs obliques orientés dans 2 directions opposées. Cette dernière unité, datée entre 3800 et 3500 ans BP, correspond à des dunes migrantes surimposées au banc et observables également à partir des données bathymétriques. La forte corrélation entre les courants tidaux et la direction apparente de migration des dunes dans le sens horaire, suggère la présence d'un gyre tidal contrôlant la dynamique actuelle de la plupart des dunes associées au banc. Un comblement important de fond de baie par migration de barres sableuses (~100m/an), et régime de flux dispersif est observé grâce de l’imagerie satellitaire et photogrammétrie SfM par drone. Le recoupement avec l’analyse exploratoire des données climatiques ERA5 du programme Copernicus a permis de préciser qu’à moyen terme (échelle décennale), la migration des barres est contrôlée par la dynamique tidale (puissance hydraulique, temps d’immersion des barres) et à court terme (échelle saisonnière) le contrôle de la dynamique intertidale semble être assuré par la houle, et les tempêtes. Cette étude propose une nouvelle approche intégrée (mer-terre) pour le suivi de la dynamique de baie
The morphology and internal structure of the Horaine banner bank are described using multibeam and high- resolution seismic reflection data, coupled with vibro-coring and radiocarbon dating. The internal structure of the bank reveals 4 seismic units (U1-U4) on a proterozoic basement (U0). The basal unit U1 is interpreted as reworked lowstand fluvial sediments those infilled micro incised valleys during a rise in sea level. This unit is overlain by paleo-coastal barrier sand-spit (U2) whose development was controlled by swell in the context of a rapid rise in sea level. The successive prograding unit (U3) is interpreted as flooding deposits in continuity with unit U2. The unit U4 is characterized by oblique reflectors oriented in two opposite directions. This last unit, dated between 3800 and 3500 yr. BP, corresponds to migrating dunes superimposed on the bank and observable in the high-resolution bathymetric data. The strong correlation between tidal currents and the apparent clockwise migration of dune crests suggests the presence of a tidal gyre controlling the present- day dynamics of most of the Horaine bank dunes. A significant filling of the bay intern part by sand bar migration (100m/year on average), and dispersive flood regime is observed thanks to satellite imagery and UAV SfM photogrammetry. The cross-check with the exploratory analysis of the ERA5 climate data of the Copernicus program allowed to specify that in the medium term (decadal scale), the migration of the bars is controlled by the tidal dynamics (hydraulic power, immersion time of the bars) and in the short term (seasonal scale) the control of the intertidal dynamics seems to be ensured by the swell, and the storms. This study proposes a new integrated approach (sea-land) for monitoring bay dynamics
