Complete 1H and 13C NMR assignments of clerodane diterpenoids of Salvia splendens.
2006
Unambiguous and complete assignments of 1H and 13C NMR chemical shifts for five clerodane diterpenes, four of them isolated from Salvia splendens (salviarin, splendidin and splenolides A and B) and one obtained by acetylation of splenolide A, are presented. The assignments are based on 2D shift-correlated [1H,1H–COSY, 1H,13C-gHSQC–1J(C,H) and 1H,13C-gHMBC-nJ(C,H) (n = 2 and 3)] and nuclear Overhauser effect (NOE) experiments. The conformation of the rings of these compounds is supported by the 3J(H,H) values and NOE results. Copyright © 2006 John Wiley & Sons, Ltd.
Usage assignment of the residence in the cases of familiar crises: commentary on the article 6 Valencian Law of familiar relations
2015
En este trabajo se analiza la regulación valenciana respecto a la atribución del uso de la vivienda familiar, tomando en consideración las sentencias dictadas en aplicación del art. 6 de la Ley de relaciones familiares. In this paper we study the Valencian regulation with regard to the assignment of the usage of the familiar residence, taking in consideration the judgments dictated in application of the article 6 law of familiar relations.
Multilevel Bandwidth and Radio Labelings of Graphs
2008
This paper introduces a generalization of the graph bandwidth parameter: for a graph G and an integer k ≤ diam(G), the k-level bandwidth Bk(G)of G is defined by Bk(G) = minγ max{|γ(x)-γ(y)|-d(x, y)+1 : x, y ∈ V (G), d(x, y) ≤ k}, the minimum being taken among all proper numberings γ of the vertices of G. We present general bounds on Bk(G) along with more specific results for k = 2 and the exact value for k = diam(G). We also exhibit relations between the k-level bandwidth and radio k-labelings of graphs from which we derive a upper bound for the radio number of an arbitrary graph.
Students’ Redesign of Mandatory Assignments in Teacher Education
2017
This article explores specific aspects of literacy practices in teacher education in Norway, building upon data collected within the research project Digital literacy and use of learning resources in teacher education in Norway (DigiGLU). Our main aim is to explore how teachers in different subject courses in teacher education (TE) design mandatory assignments, and how students respond to these designs. After the extensive TE-reform in 2010, in revised plans and documents guiding professional training, mandatory assignments (both form and content) were considered more important for the students’ learning process. In our investigation, the concepts of design for learning and design in learni…
Il provvedimento di assegnazione della casa familiare su un immobile ipotecato: quando le ragioni creditorie prevalgono su quelle della famiglia
2018
L'articolo, partendo dall'analisi di una sentenza del Tribunale di Bari, si occupa del provvedimento di assegnazione della casa familiare e della relativa opponibilità al creditore ipotecario che abbia acquistato il suo diritto in base ad atto iscritto anteriormente alla emissione o trascrizione del provvedimento stesso The article, starting from the analysis of a sentence of the Court of Bari, deals with the provision of assignment of the family home and its enforceability to the mortgage lender who has acquired his right on the basis of an act written before the issuance or transcription of the provision same
Multidimensional scaling and stock location assignment in a warehouse: an application
1999
By means of an application, in the present paper, the suitability of a multivariate statistical methodology, as multidimensional scaling (MDS), to solve an optimization problem is shown. In particular, considering the stock location assignment problem in the warehouse of a supermarket chain, the solution gained by applying MDS to a set of seven variables is compared with the one obtainable by considering the usual techniques applied in this context. A wide discussion of results is reported.
Effects of environment and genotype on dispersal differ across departure, transfer and settlement in a butterfly metapopulation
2022
Active dispersal is driven by extrinsic and intrinsic factors at the three stages of departure, transfer and settlement. Most empirical studies capture only one stage of this complex process, and knowledge of how much can be generalized from one stage to another remains unknown. Here we use genetic assignment tests to reconstruct dispersal across 5 years and 232 habitat patches of a Glanville fritillary butterfly ( Melitaea cinxia ) metapopulation. We link individual dispersal events to weather, landscape structure, size and quality of habitat patches, and individual genotype to identify the factors that influence the three stages of dispersal and post-settlement survival. We found that ne…
Il ruolo dell'informazione contestuale e delle componenti sillabico-accentuali nella decodifica del testo scritto: un confronto tra dislessici evolut…
2010
L'esperimento qui presentato si propone di valutare l'importanza che assume, per un dislessico evolutivo rispetto ad un normolettore, la presenza di indizi che suggeriscano il significato del testo scritto (informazioni contestuali), nonché l'influenza di determinate caratteristiche sillabico-accentuali nelle prestazioni di lettura. Lo studio è stato condotto attraverso la somministrazione di frasi in ognuna delle quali è stata inserita una parola target secondo criteri relativi alla posizione (dislocazione a sinistra e dislocazione a destra) al fine di valutare l'influenza esercitata dall'informazione contestuale durante la decifrazione del testo. Le parole selezionate sono state accuratam…
A note on rank 2 diagonals
2020
<p>We solve two questions regarding spaces with a (G<sub>δ</sub>)-diagonal of rank 2. One is a question of Basile, Bella and Ridderbos about weakly Lindelöf spaces with a G<sub>δ</sub>-diagonal of rank 2 and the other is a question of Arhangel’skii and Bella asking whether every space with a diagonal of rank 2 and cellularity continuum has cardinality at most continuum.</p>
An Exact Algorithm for the Quadratic Assignment Problem on a Tree
1989
The Tree QAP is a special case of the Quadratic Assignment Problem (QAP) where the nonzero flows form a tree. No condition is required for the distance matrix. This problem is NP-complete and is also a generalization of the Traveling Salesman Problem. In this paper, we present a branch-and-bound algorithm for the exact solution of the Tree QAP based on an integer programming formulation of the problem. The bounds are computed using a Lagrangian relaxation of this formulation. To solve the relaxed problem, we present a Dynamic Programming algorithm which is polynomially bounded. The obtained lower bound is very sharp and equals the optimum in many cases. This fact allows us to employ a redu…
