Influència del sexe i l'edat en el raonament moral prosocial dels estudiants de secundària
2008
Aquest treball presenta una aproximació a l'estudi del raonament moral prosocial i de les variables que infl ueixen en el seu desenvolupament. L'objectiu principal és determinar en quina mesura la variable sexe i la variable edat infl ueixen en el raonament moral prosocial dels adolescents. L'estudi es realitza amb una mostra d'estudiants de secundària (n=114), homes i dones. Els resultats indiquen que les dues variables analitzades (sexe i edat) tenen un efecte signifi catiu sobre el raonament moral prosocial. Les dones, davant una situació d'ajudar o no l'altre, justifi quen la decisió en raons més abstractes i internalitzades, enfront dels homes, que se centren en l'aprovació i acceptaci…
SINDROME DA ATTIVAZIONE MACROFAGICA SECONDARIA AD IMMUNODEFICIT
2018
Introduzione: la sindrome da attivazione macrofagica (SAM) è una condizione clinica rara, di cui esistono forme primitive (es. deficit di perforine) e secondarie ad infezioni, farmaci, immunodeficit; nel 10% dei casi rappresenta una complicanza dell'artrite idiopatica giovanile sistemica (AIG). Criteri diagnostici: febbre, epatosplenomegalia, citopenia bilineare, aumento di ferritina, transaminasi, ipertrigliceridemia ed ipofibrinogenemia con segni di emofagocitosi all'aspirato midollare. Terapia: metilprednisolone a 30 mg/Kg/die ev e terapia della patologia di base; nei no-responders trova impiego l'uso dei farmaci immunosoppressori come ciclosporina, Anakinra per forme secondarie ad AIG, …
PLANT SUCCESSION ON SICILIAN TERRACES
2007
189 phytosociological relevés have been made in five areas of Sicily, three on volcanic substrates and two on limestones, to study plant community succession trends within abandoned terraced vineyards and cereal fields. Disturbance status and abandonment age was recorded for each sample plot. DCA of these relevés suggests that four are the most important factors driving succession, i.e. geological substrate, bioclimate, age of abandonment and disturbance. In most cases - if there are some dispersal centres near the old fields - undisturbed and less disturbed terraces evolve quite rapidly towards the local potential “climax” community. Different tren…
FTIR spectroscopy studies of high pressure-induced changes in pork macromolecular structure
2019
Abstract High pressure processing (HPP) allows to extend the shelf life of meat and meat products by pressurization of microorganisms. At the same time, HPP can induce changes of the protein structure. Vacuum-packed pork chops were HPP-treated at 300, 600 MPa for 1 or 15 min. Samples of raw, cooked and HPP-treated meat muscles and juice were analysed to evaluate the structure of macromolecules. HPP caused visible discolouration of pork chops; hence, the colour of pork meat surface was tested. The lightness (colour component L*) was directly proportional to the applied pressure, probably due to the increased protein denaturation by high pressure. Pork meat muscle and juice samples were analy…
Les scolarités de la maternelle au lycée. Etapes et processus dans la production des inégalités sociales
1993
Marie Duru-Bellat, Jean-Pierre Jarousse, Alain Mingat : Die Schullaufbahnen von der Vorschule bis zum Gymnasium. Etappen und Prozesse in der Entstehung der sozialen Ungleichheit. Die Daten der Schuldemographie zeigen wichtige soziale Unterscheidungen beim Zugang zu identifizierten Schullaufbahnebenen wie Abitur oder Hochschule. Zwar ist dièse transversale Perspektive nützlich, sie ist jedoch unzureichend, um festzulegen, nach welchem "Kalender" und durch welche Mechanismen diese Unterscheidungen nach und nach entstehen. Dieser Artikel möchte die verschiedenen Rollen jeder dieser Unterrichtsebenen bewerten und dabei unterscheiden, was auf soziale Erfolgsunterschiede zuruckzufiihren ist, und …

Acoustic doppler velocity profiler for velocity and turbulence measurements in a large amplitude meandering flume
2008
Flow over deformed bed of a meandering laboratory channel is experimentally investigated. The velocity components have been obtained using an Ultrasonic Doppler Profiler (DOP2000) that measures the instantaneous flow velocity profile along the probe direction. In this work, some results obtained in peculiar sections along the channel are reported. A refined mesh of the measurement points has been used for each considered cross-section. The analysis of the collected data essentially confirms that when the aspect ratio is small the secondary circulation assumes great importance and, in accordance with previous findings, a second counter-rotating secondary circulation cell appears near the fre…
L'enseignement des langues vivantes à l'école élémentaire : éléments d'évaluation des effets au collège
1997
This evaluation is based on a longitudinal survey carried out over two years concerning 1 500 pupils who started secondary school. Some of them were initiated in English in the last two grades of Primary school (experimentation launched by the Ministry of Education), the other pupils had started learning English at Secondary School. Two kinds of results were obtained : first, we described a certain number of factors that influence pupils' acquisitions in English ; second, we tried to show the extent to which the outcome of early initiation explains the differences between pupils during the secondary school. It appears finally that the impact of English initiation at the Primary school seems…
L’acquisizione delle categorie morfologiche in apprendenti adulti analfabeti o bassamente scolarizzati: un’indagine sperimentale.
2016
L’incremento dei flussi immigratori verso l’Europa ha da qualche anno riportato alla ribalta il tema dell’analfabetismo. Molte realtà (tra queste, alcune universitarie) impegnate nella didattica dell’italiano a stranieri sono chiamate a raccogliere la sfida posta dalla presenza di apprendenti adulti analfabeti (in lingua madre) o bassamente scolarizzati. L’alfabetizzazione di apprendenti scarsamente scolarizzati costituisce un nuovo campo d’intervento didattico, che ha alle spalle un orizzonte teorico piuttosto consistente (cfr. LESLLA). La ricerca acquisizionale suggerisce non solo che le abilità orali e di scrittura si condizionano vicendevolmente (per esempio, le capacità astrattive conn…
Aeration tank and secondary clarifier as one system. in "Activated Sludge Separation Problems: Theory, Control Measures, Practical Experieces. Eds. R…
2017
Traditionally the activated sludge process is treated as two stage process. The first stage (aeration basin) is described in terms of biological processes while the description of the second stage concentrates on processes of biomass separation and thickening. The modern approach to the activated sludge process looks at both the biological and the separation stage as one system. The aim of this chapter is to explain the interactions between the two parts of the activated sludge system.
