Monochromatic Long-Period Seismicity Prior to the 2012 Earthquake Swarm at Little Sitkin Volcano, Alaska

2021

Detection of the earliest stages of unrest is one of the most challenging and yet critically needed aspects of volcano monitoring. We investigate a sequence of five unusual long-period (LP) earthquakes that occurred in the days prior to the onset of a months-long volcano-tectonic (VT) earthquake swarm beneath Little Sitkin volcano in the Aleutian Islands during late 2012. The long-period earthquakes had two distinctive characteristics: their signals were dominated by a monochromatic spectral peak at approximately 0.57 Hz and they had impulsive P and S-wave arrivals on a seismometer located on Amchitka Island 80 km to the southeast of the volcano. In each case, the monochromatic earthquakes …

Cervical necrotizing fasciitis and descending necrotizing mediastinitis in a patient affected by neglected peritonsillar abscess: a case of medical n…

2007

Abstract We report a case of fatal cervical necrotizing fasciitis (CNF) and descending necrotizing mediastinitis (DNM) due to primary peritonsillar abscess in 60-year-old male patient with no history or evidence of immunocompromising disorders. The patient was treated with antibiotic and corticosteroid drugs but he developed mediastinitis and septic shock and died of multiple organ failure six days later from recovery in hospital. After a clinical, diagnostic and therapeutical consideration of the cervical necrotizing fasciitis and some related risks of a delayed diagnosis and treatment, the authors analysed the clinical history of the patient and of the medical conduct pointing out profess…

Tonalite sill emplacement at an oblique plate boundary: northeastern margin of the Bohemian Massif

1997

Abstract A tonalitic sill has been examined at the Variscan transpressive boundary of the Lugian and Silesian plates at the NE margin of the Bohemian Massif. A structural, petrological and geochronological study reveals that it was emplaced syn-tectonically with major ductile shearing in lower crustal rocks. Magmatic and pre-rheological critical melt percentage (RCMP) fabrics are concordant with the hanging wall structures but discordant with those of the footwall. The AMS study shows the predominance of flattening strain at the margins and plane strain fabrics in the core. Numerical modelling of AMS fabrics is in good agreement with the hypothesis of magma flow and deformation in oblique t…

Green conditions for the Suzuki reaction using microwave irradiation and a new HNT- supported ionic liquid-like phase (HNT-SILLP) catalyst

2014

A new catalytic system based on modified halloysite nanotubes was employed in the Suzuki reaction under microwave irradi- ation. A set of solvents, times and bases was screened and the best experimental conditions were obtained when the reactions were carried out for 10 min in water–ethanol at 120 °C in presence of K2CO3 as base. Good recyclability was observed. The new catalytic system was employed using either 1 mol% or 0.1 mol%. The palladium catalyst displayed good activity, allowing the synthesis of several biphenyl compounds in high yield working with only 0.1 mol% palladium loading. The application of mi- crowave irradiation decreased the reaction time and also improved conversion wi…

L’image des légumes

2017

Au sein du vaste champ de recherche qu’est l’alimentation, les légumes et les représentations qu'en ont les mangeurs ont été délaissés malgré la place importante qu'ils occupent dans les discours officiels depuis la mise en place en 2001 du PNNS. Dans un contexte de stagnation de leur consommation, il semble judicieux de tenter de comprendre quels en sont les freins. Notre hypothèse veut que les discours médiatiques sur le sujet, dans la lignée du discours des autorités publiques, présentent les légumes avant tout comme un aliment fonctionnel, dans un pays où le goût et le plaisir restent pourtant des piliers de la culture alimentaire. Pour mettre à l’épreuve ce postulat, notamment à traver…

Sensory biology of Phalangida harvestmen (Arachnida, Opiliones): a review, with new morphological data on 18 species

2009

Sensory biology of Phalangida harvestmen (Arachnida, Opiliones): a review, with new morphological data on 18 species. 2014Acta Zoologica (Stockholm) 90: 2092013227 Phalangida includes three of the four suborders of Opiliones (Arachnida): Eupnoi, Dyspnoi and Laniatores. We review the literature on the sensory structures and capabilities of Phalangida, provide new morphological data for 18 species and discuss the 11 sensory structures that have been described in the group. Based on the published data encompassing both behaviour and morphology, three conclusions are apparent: (1) species of Phala…

Development of antennal sensilla during moulting inNeomysis integer (Leach) (Crustacea, Mysidacea)

1980

The sensilla are associated with 6 enveloping cells. The innermost enveloping cell (e 1) secretes the dendritic sheath (=thecogen cell). All other enveloping cells are involved in the formation of the outer cuticular apparatus in secreting the cuticle of a definite region of the new hair shaft. The development of the new sensilla begins when an exuvial space expands between old cuticle and epithelium. The newly forming hair shafts lie folded back in an invagination of the epidermal tissue. Only a distal shaft part projects into the free exuvial space. The cuticle of the distal and middle shaft region is secreted by the three middle enveloping cells (e 2–e 4) (=trichogen cells), which are ar…
