Chitinozoan biozonation and new lithostratigraphical data in the upper Ordovician of the Fauquez and Aquempont areas (Brabant Massif, Belgium)

A chitinozoan biozonation is established for the Upper Ordovician rocks of the Sennette valley in the Fauquez area and the Asquempont area, revising the existing chitinozoan biozonation of the Brabant Massif. The chitinozoans of five formations (the Ittre, Bornival, Huet, Fauquez and Madot formations) are studied from 70 samples. The chitinozoan biozonation is correlated with Baltoscandia and the Avalonian Upper Ordovician type sections in the U.K. This correlation provides an accurate dating of the studied formations. A megaslumping event, affecting a part of the Ittre and Bornival Formation and causing the overturning of a pile of sediments estimated at minimum 200 m thick, may be placed in the mid Oandu (Cheneyan, middle Caradoc, early Stage 6"?). The volcanic rocks in the Fauquez area, formally thought to be restricted to the Ashgill, are confined to the late Caradoc - early Ashgill timespan. In addition to this, this paper presents new lithostratigraphical data on the Ittre Formation and the lower member of the Bornival Formation

The stratigraphy of the type locality of the ?Late Wenlock/Early Ludlow Mont Godart formation and the Early Ludlow Ronquières formation, Brabant Massif

The Silurian of the Brabant Massif crops out in the Sennette valley, near Ronquières. From these outcrops, the Mont Godart Formation is defined and the formerly poorly defined Ronquières Formation is redescribed in detail. Seven informal units, four of them divided into subunits, are distinguished in the Ronquières Formation. Based on Chitinozoa and graptolites, the age of the Mont Godart Formation is estimated possibly latest Homerian (Wenlock) or earliest Gorstian (Ludlow) and that of the Ronquières Formation as Gorstian (Ludlow). Four sedimentological facies occur: mud-grade turbidites predominate and are interbedded in anoxic laminated hemipelagites. Oxic bioturbated hemipelagites and metabentonites occur rarely. The palaeoenvironment of the sedimentary basin is interpreted as a turbiditic fan system directed to the east in a E-W trending trough with apparently northward directed currents. A major megacycle spans both formations. Relatively high energy sediments are present in the bottom of the Mont Godart Formation and in the top of the Ronquières Formation. Less energetic sediments, indicating a deeper sea environment, are found in between. A similar cycle of deepening and shallowing has also been observed in the late Wenlock and early Ludlow of the Welsh Borderland and of Gotland on the Baltic platform

Contemporary management of primary parapharyngeal space tumors

The parapharyngeal space is a complex anatomical area. Primary parapharyngeal tumors are rare tumors and 80% of them are benign. A variety of tumor types can develop in this location; most common are salivary gland neoplasm and neurogenic tumors. The management of these tumors has improved greatly owing to the developments in imaging techniques, surgery, and radiotherapy. Most tumors can be removed with a low rate of complications and recurrence. The transcervical approach is the most frequently used. In some cases, minimally invasive approaches may be used alone or in combination with a limited transcervical route, allowing large tumors to be removed by reducing morbidity of expanded approaches. An adequate knowledge of the anatomy and a careful surgical plan is essential to tailor management according to the patient and the tumor. The purpose of the present review was to update current aspects of knowledge related to this more challenging area of tumor occurrence.Peer reviewe

Many Labs 2: Investigating Variation in Replicability Across Samples and Settings

We conducted preregistered replications of 28 classic and contemporary published findings, with protocols that were peer reviewed in advance, to examine variation in effect magnitudes across samples and settings. Each protocol was administered to approximately half of 125 samples that comprised 15,305 participants from 36 countries and territories. Using the conventional criterion of statistical significance (p < .05), we found that 15 (54%) of the replications provided evidence of a statistically significant effect in the same direction as the original finding. With a strict significance criterion (p < .0001), 14 (50%) of the replications still provided such evidence, a reflection of the extremely highpowered design. Seven (25%) of the replications yielded effect sizes larger than the original ones, and 21 (75%) yielded effect sizes smaller than the original ones. The median comparable Cohen’s ds were 0.60 for the original findings and 0.15 for the replications. The effect sizes were small (< 0.20) in 16 of the replications (57%), and 9 effects (32%) were in the direction opposite the direction of the original effect. Across settings, the Q statistic indicated significant heterogeneity in 11 (39%) of the replication effects, and most of those were among the findings with the largest overall effect sizes; only 1 effect that was near zero in the aggregate showed significant heterogeneity according to this measure. Only 1 effect had a tau value greater than .20, an indication of moderate heterogeneity. Eight others had tau values near or slightly above .10, an indication of slight heterogeneity. Moderation tests indicated that very little heterogeneity was attributable to the order in which the tasks were performed or whether the tasks were administered in lab versus online. Exploratory comparisons revealed little heterogeneity between Western, educated, industrialized, rich, and democratic (WEIRD) cultures and less WEIRD cultures (i.e., cultures with relatively high and low WEIRDness scores, respectively). Cumulatively, variability in the observed effect sizes was attributable more to the effect being studied than to the sample or setting in which it was studied.UCR::Vicerrectoría de Investigación::Unidades de Investigación::Ciencias Sociales::Instituto de Investigaciones Psicológicas (IIP

Accumulation des métaux lourds d'origine autoroutière (Fe, Pb, Cu, Zn) dans les bassins d'orage

Lors d'une étude sur l'amélioration de la capacité épuratrice des bassins d'orage autoroutiers, des analyses de concentration en métaux lourds (fer, plomb, zinc et cuivre) ont été réalisées dans les eaux, les sédiments, la végétation et les macro-invertébrés
