A binary system of complementizers in Cimbrian relative clauses

The system of Cimbrian relative clauses manifests itself in a complex scenario: two different complementizers occur in this context: i) the ‘autochthonous’ (Germanic) bo, cognate of Southern German wo, and ii) the ‘allochthonous’ ke, borrowed from Italian (che), which is gradually spreading. In our paper we provide empirical evidence for a crucial specialization of both complementizers: the former shows up only in restrictive relative clauses, the latter in both restrictive and non-restrictive relatives, giving rise to a binary system. In our analysis we aim to explain the binary system of Cimbrian relative complementizers directly addressing the general discussion about relative clauses, showing once more the relevance of both linguistic contact and microvariation for the theory of grammar

Hierarchical Poly Tree Configurations for the Solution of Dynamically Refined Finte Element Models

This paper demonstrates how a multilevel substructuring technique, called the Hierarchical Poly Tree (HPT), can be used to integrate a localized mesh refinement into the original finite element model more efficiently. The optimal HPT configurations for solving isoparametrically square h-, p-, and hp-extensions on single and multiprocessor computers is derived. In addition, the reduced number of stiffness matrix elements that must be stored when employing this type of solution strategy is quantified. Moreover, the HPT inherently provides localize 'error-trapping' and a logical, efficient means with which to isolate physically anomalous and analytically singular behavior

Finite element for rotor/stator interactive forces in general engine dynamic simulation. Part 1: Development of bearing damper element

A general purpose squeeze-film damper interactive force element was developed, coded into a software package (module) and debugged. This software package was applied to nonliner dynamic analyses of some simple rotor systems. Results for pressure distributions show that the long bearing (end sealed) is a stronger bearing as compared to the short bearing as expected. Results of the nonlinear dynamic analysis, using a four degree of freedom simulation model, showed that the orbit of the rotating shaft increases nonlinearity to fill the bearing clearance as the unbalanced weight increases

Analysis and optimization of PCM enhanced storage tanks for Solar Domestic Hot Water systems

A storage device is a fundamental component to enhance the efficiency of the Solar Domestic Hot Water plants. The efficiency of the storage tanks has been investigated through simulation and optimization tools. A PCM model has been implemented in ESP-r and a new plant component has been inserted in the software database. For the type of components/plants analyzed, the improvement provided by the PCM insertion is not dramaticDipartimento di aggregazione: Dipartimento di Ingegneria ed Architettura dell'Università degli studi di TriesteopenDottorato di ricerca in Tecnologie chimiche ed energeticheembargoed_20151115Padovan, Robert

Soluble CD40 ligand can replace the normal T cell-derived CD40 ligand signal to B cells in T cell-dependent activation

We have constructed a soluble chimeric fusion protein between the mouse CD8 alpha chain and the mouse CD40 T cell ligand. This protein binds to both human and mouse B cells. By itself it induced a modest degree of B cell proliferation, but together with anti-immunoglobulin (anti-Ig) antibody it greatly stimulated B cell proliferation, as determined by both [3H]thymidine uptake and increase in cell numbers. These data are evidence that the CD40 ligand on T cells provides a signal that drives B cell proliferation. This signal is synergistic with that delivered by anti-Ig antibody
