Monthly Bonaire coral Sr/Ca and oxygen isotope data from 118 kyr ago (coral BON-5-D)
2015
The end of the last interglacial period, ~118 kyr ago, was characterized by substantial ocean circulation and climate perturbations resulting from instabilities of polar ice sheets. These perturbations are crucial for a better understanding of future climate change. The seasonal temperature changes of the tropical ocean, however, which play an important role in seasonal climate extremes such as hurricanes, floods and droughts at the present day, are not well known for this period that led into the last glacial. Here we present a monthly resolved snapshot of reconstructed sea surface temperature in the tropical North Atlantic Ocean for 117.7±0.8 kyr ago, using coral Sr/Ca and d18O records. W…
Boundary value steady solutions of a class of hydrodynamic models for vehicular traffic flow
2003
This paper deals with the solution of a boundary value problem related to a steady nonuniform description of a class of traffic flow models. The models are obtained by the closure of the mass conservation equation with a phenomenological relation linking the local mass velocity to the local density. The analysis is addressed to define the proper framework toward the identification of the parameter characterizing the model. The last part of the paper develops a critical analysis also addressed to the design of new traffic flow models.
The ladybird homeobox genes are essential for the specification of a subpopulation of neural cells
2004
AbstractIn Drosophila, neurons and glial cells are produced by neural precursor cells called neuroblasts (NBs), which can be individually identified. Each NB generates a characteristic cell lineage specified by a precise spatiotemporal control of gene expression within the NB and its progeny. Here we show that the homeobox genes ladybird early and ladybird late are expressed in subsets of cells deriving from neuroblasts NB 5-3 and NB 5-6 and are essential for their correct development. Our analysis revealed that ladybird in Drosophila, like their vertebrate orthologous Lbx1 genes, play an important role in cell fate specification processes. Among those cells that express ladybird are NB 5-6…

Olej w obrzędach inicjacji chrześcijańskiej w syro-orientalnej tradycji liturgicznej
2021
Olej należy do najważniejszych elementów naturalnych, jakie weszły do liturgii Kościoła. Chociaż używa się go w różnych obrzędach sakramentalnych i pozasakramentalnych, to jednak najbogatszą wymowę teologiczną zyskał w obrzędach chrześcijańskiej inicjacji. Niniejsze studium stanowi refleksję nad rolą i znaczeniem oleju w liturgii chrzcielnej w tradycji syro-orientalnej. W pierwszej kolejności przypomniana została nomenklatura związana z namaszczeniami w tradycjach syryjskich. Następnie czytelnik może zapoznać się z symboliką oleju i namaszczeń, jaką spotykamy w twórczości najważniejszych Ojców syryjskich. W ostatniej części zaprezentowane zostały namaszczenia w liturgicznym obrzędzie chrzci…
Aerobic granular sludge treating shipboard slop: Analysis of total petroleum hydrocarbons loading rates on performances and stability
2018
Abstract The work focuses on the feasibility of treating slop with aerobic granular sludge. For this purpose, a 3.5 L granular sequencing batch reactor was activated and it was monitored for 156 days. The experimental campaign was divided into two periods, named Period I (100 days) and Period II (56 days). Total Petroleum Hydrocarbon (TPH) concentration in the slop was, on average, equal to 6.8 ± 1.5 mg L−1 and 13 ± 1.5 mg L−1 in Period I and Period II respectively. The obtained results during the first experimental period indicated that about 80 days were required to reach steady state with mature granules, when TPHs removal efficiency was approximately 90%. The results indicated that both…
New method to determine the true transmissibilities and permeabilities of oxygen in hydrogel membranes
1999
In the present paper, an electrochemical method to obtain the true transmissibilities and permeabilities of hydrogels to oxygen is proposed. The method involves the measurement of the electric current arising from the flow of oxygen through a potentiostat cell integrated by a top water layer, the hydrogel membrane, and a thin water layer between the membrane and the cathode, where the oxygen is reduced. Varying the thickness of the top water layer, the true permeation characteristics of the hydrogels are obtained. A parallel study was carried out in which the transmissibilities and permeation coefficients were obtained from the variation of the steady state current with the thickness of the…

La didactique clinique comme mode d’accès aux savoirs des enseignants en ÉPS : le cas de l’enseignement du judo
2018
Cette étude à visée exploratoire et compréhensive met en évidence les savoirs personnels des enseignants transmis en cours d’ÉPS. La recherche présente trois vignettes didactiques cliniques d’enseignants spécialistes de judo. Les résultats montrent que ces savoirs personnels se sont construits pendant la pratique sportive du judo lorsque ceux-ci étaient de jeunes pratiquants. Le rôle du « déjà-là expérientiel » et ses effets sur les conceptions des professeurs sont mis en avant, en lien avec les savoirs personnels. Compte tenu des effets déterminants des « déjà-là expérientiels et conceptuels », nous proposons quelques pistes de travail pour la formation initiale des enseignants d’ÉPS.
Phytoplankton equilibrium phases during thermal stratification in a deep subtropical reservoir
2008
SUMMARY 1. Equilibrium and non-equilibrium hypotheses have often been used to explain observations in community ecology. Published case studies have demonstrated that steady state phytoplankton assemblages are more likely to occur in deep lakes than in shallow mixed ones. 2. Phytoplankton seasonal succession was studied by weekly sampling in Faxinal Reservoir (S Brazil), a subtropical deep, clear, warm monomictic and slightly eutrophic reservoir. This study demonstrated an alternation of steady and non-steady state phases of phytoplankton assemblages with different dominant species during the steady states. 3. During the studied period, three steady states were identified with different dom…
