The nasus gland: A new gland in soldiers of Angularitermes (Termitidae, Nasutitermitinae)

2015

Termites have developed many exocrine glands, generally dedicated to defence or communication. Although a few of these glands occur in all termite species, or represent synapomorphies of larger clades, others are morphological innovations of a single species, or a few related species. Here, we describe the nasus gland, a new gland occurring at the base of the nasus of Angularitermes soldiers. The nasus gland is composed of class 1, 2, and 3 secretory cells, a rare combination that is only shared by the sternal and tergal glands of some termites and cockroaches. The ultrastructural observations suggest that the secretion is produced by class 2 and 3 secretory cells, and released mostly by cl…

EFFICACIA TEMPORALE DEL PERMESSO DI COSTRUIRE NELLA DISCIPLINA URBANISTICA DELLA REGIONE SICILIANA

2016

L’efficacia temporale del provvedimento di permesso a costruire prevede un termine d’inizio dei lavori, non superiore ad un anno dal rilascio del titolo, e un termine di ultimazione dell’opera da completarsi entro un periodo di tre anni dall’inizio dell’attività.Il permesso di costruire decade, inoltre, con l’entrata in vigore di contrastanti previsioni urbanistiche, salvo che i lavori siano già iniziati e vengano completati entro il termine di tre anni dalla data di inizio.al fine di affrontare la grave crisi economico-finanziaria, nell'ambito di disposizioni urgenti per il rilancio dell’economia (c.d. “decreto del fare”), si è previsto che “salva diversa disciplina regionale, previa comun…

Les exercices gradués dans la méthode du Grammalessico francese a uso degl’italiani d’Arminio Wurmbrand Bianchi

2020

L’article se propose d’analyser les exercices du manuel d’Arminio Wurmbrand Bianchi, Grammalessico francese a uso degl’italiani, qui ont une forme et une structure que l’on retrouve dans de nombreux manuels s’inspirant des méthodes dites « synthétiques ». Wurmbrand, en effet, introduit dans son manuel une nouveauté pour pourvoir au caractère incomplet de la méthode synthétique : il propose, ainsi, avant chaque exercice, la traduction des seuls termes « radicalement dissemblables » des deux langues « similaires à l’origine » qui caractérisent la langue française et la langue italienne. Le but est de fournir aux élèves la maîtrise lexicale de la langue française avec une attention toute parti…

The fine structure of colleterial glands in two cockroaches and three termites, including a detailed study of Cryptocercus punctulatus (Blattaria, Cr…

2007

1873-5495 (Electronic) Journal Article Research Support, U.S. Gov't, Non-P.H.S.; The colleterial glands of insects are organs associated with the female genital apparatus. In cockroaches, these glands produce secretions that cover two parallel rows of eggs during oviposition, and in oviparous species, these secretions become the tanned, sculpted, rigid outer casing of the ootheca. The goal of this study was to compare the gross anatomy of the colleterial glands and the ultrastructure of their component tubules in the phylogenetically significant genera Cryptocercus (Blattaria) and Mastotermes (Isoptera). Recent studies indicate that cockroaches in the genus Cryptocercus are the sister group…

Enseñanza de E/LE y fraseología: algunas consideraciones teórico-prácticas para la enseñanza de fraseología a aprendices germano-hablantes (I)

2012

El aprendizaje de unidades fraseológicas (UFS) en clase de español como lengua extranjera ha ido cobrando protagonismo en los últimos años. Dado el alto índice de frecuencia de aparición y el carácter coloquial de muchas de estas, un gran número de autores creen indispensable aproximar al alumno, desde niveles iniciales, al conocimiento de ciertas combinaciones fijas de palabras cuya significación no suele ser composicional, esto es, que el alumno no puede descifrar su significado partiendo del vocabulario que conoce. Pero, ¿qué tipo de UFS y en qué cursos resulta más rentable enseñar al aprendiz de E/LE? ¿Y qué variedad, en el caso de una lengua claramente policéntrica como el español: pen…

Effects of juvenile hormone analogues upon soldier differentiation in the termite Reticulitermes santonensis (Rhinotermitidae, Heterotermitinae).

2018

Under the influence of juvenile hormone analogues (JHAs), termite workers are induced to differentiate into soldiers. In Reticulitermes santonensis, such induced differentiation is often incomplete, resulting in intercaste production. The morphology of the structures most affected during differentiation was analyzed descriptively and biometrically in normal workers, presoldiers, and soldiers, and in experimental intercastes. We observed that intercastes form a morphological and biometrical continuum between workers and presoldiers (presoldier intercastes), and between presoldiers and soldiers (soldier intercastes). We also compared the biochemistry of the normal individuals and of the inter…
