MATEMATICA(MENTE) POSSIBILE. I SERVIZI EROGATI AGLI STUDNETI CON DSA PRESSO L'UNIVERSITA' DEGLI STUDI DI MODENA E REGGIO EMILIA
No full textIndagini recenti indicano come oggi in Italia sia crescente il numero degli studenti di ogni ordine e grado scolastico che incontrano problemi nell'apprendimento del sistema dei numeri, manifestando difficoltà relative a: riconoscimento e denominazione dei singoli numerici, scrittura dei numeri, associazione del simbolo numerico alla quantità corrispondente, numerazione in ordine crescente e decrescente, risoluzione di situazioni problematiche, sintomatiche della discalculia. Il contributo rende noti i serviz erogati agli studenti con DSA presso l'Università degli Studi di Modena e Reggio Emilia
POLLEN DEVELOPMENT IN LIRIODENDRON-TULIPIFERA - SOME UNUSUAL FEATURES
No full textPollen development in Liriodendron tulipifera has some unusual features. Two arrangements in tetrads could be detected: isobilateral and decussate types. The occurrence of one or the other pattern seems to be random. The sulcus position is marked early by an exine fold forming at the beginning of wall deposition at the distal pole of tetrad cells. During increasing microspore volume, the exine outgrowth is unfolded, then stretched and finally broken up, thus exposing the intine below. Plastids are usually excluded from the generative cell, indicating that their inheritance is predominantly maternal. Nevertheless our cytological results give evidence of a trace paternal transmission of plastids. Some evolutionary considerations are mad
I SERVIZI A FAVORE DEGLI STUDENTI CON DSA PRESSO L'UNIVERSITAì DEGLI STUDI DI MODENA E REGGIO EMILIA
No full textCon la pubblicazione nella "gazzetta ufficiale" della Legge n. 170 del'8 Ottobre 2010, nuove norme in materia di disturbi specifici di apprendimento in ambito scolastico, la difficoltà di apprendimento ha ottenuto un suo riconoscimento anche a livello normativo. La Legge 170 e le successive Linee Guida allegate chiariscono, prendendo in considerazione specificatamente ogni ordine e grado scolastico, quali siano le misure dispensative e gli strumenti compensativi a disposizione dei soggetti con DSA. L'articolo descrive in maniera concisa la moltitudine di misure e di strumenti previsti ed ad oggi utilizzati in ambito sia scolastiche che clinico-riabilitativo al fine di favorire una sempre più efficiente acquisizione di conoscenze individuali. Il fine ultimo di questo articolo è quello di conoscere e quindi riconoscere all'interno delle indicazioni cliniche formulate per ogni soggetto con DSA i servizi che potrebbero essergli erogati in ambito accademico

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
FDPS finish line design and tooth preparation technique
No full textThe purpose of this research is to perform and verify the modified 50° preparation suggested by the authors. This procedure was performed with a scrupulous standardization of the tooths preparation and then of the laboratory techniques to produce a metal-ceramic crown, and the same for the crown cementation technique of on the preparation of the original sample. After the esthetic evaluations, the obtained sample was included in EPON resin and sectioned in the lingual-vestibular sense. The sections were then observed with an optical microscope in different magnifications for the final evaluations. The geometric design proposed presents the advantages of two great preparation techniques: 50° preparation and circumferential shoulder. The 50° bevel designed in first phase of preparation and the second phase of the circumferential 27° shoulder, together allowed to satisfy the following requirements: aesthetic, marginal accuracy, periodontal compliance, conservation and stability. However, this type of prosthetic preparation is not the only one, but it is one of the marginal designs in prosthetic dentistry
MEDICAGO TRUNCATULA ROOTS OVEREXPRESSING THE NSLTP N5 DISPLAY MODIFICATIONS IN THE LIPID PROFILE AND CHANGES IN THE EXPRESSION OF GENES INVOLVED IN LIPID METABOLISM AFTER SINORHIZOBIUM MELILOTI INFECTION
No full textTo shed light on the of MtN5 during early symbiotic events, we investigated the metabolic pathways for lipid production associated with the MtN5overespression. We carried out a comparative transcriptomic analysis of MtN5overexpressing (MtN5ox) and wild type roots after 72h of Sinorhizobium meliloti inoculation; in the same experimental conditions, we assayed the effects of MtN5 overexpression on the root lipid profile. In MtN5ox roots, we identified a quite relevant number of differential expressed genes involved in lipid transport and metabolism. The major changes were detected in genes implicated in phopholipid signalling pathways such as myo-inositol 1-phosphate synthases, phosphatidylinositolspecific phospholipase, phosphatidylinositol kinases, phosphatidylinositol transfer protein, inositol mono-phosphatase. All these transcripts were down-regulated in inoculated MtN5ox roots. Interestingly we demonstrated that MtN5 functioning is dependent on phospholipase D but not on phospholipase C activity (Pii et al., 2012). The analysis of the root lipid fraction revealed that MtN5 overexpressing roots displayed a general increase in the lipid content, that was especially relevant for galactolipids that are component of plastid and symbiosome membranes
